Patent document 1: japanese laid-open patent publication No. 2002-119634

Disclosure of Invention

Problems to be solved by the invention

However, when the operation of the pin elevator is accelerated in order to quickly arrange the pins at a predetermined position on the lane, there is a high possibility that the pins arranged on the lane will fall down due to an inertial force acting on the pins when the pin elevator is stopped, a shock when the pin elevator is operated, or the like.

In view of the above, the present invention is directed to preventing a pin disposed on a lane from falling down.

Means for solving the problems

In order to achieve the above object, a first aspect of the present invention is a bowling pin setter for applying to a bowling game apparatus in which a player rolls a ball onto a plurality of pins arranged upright on a lane to thereby topple the plurality of pins arranged upright, the pin setter including pins arranged at predetermined positions on the lane, the bowling pin setter including: a bottle lifter for lifting the pins in the vertical state to the lane; a pin guide for preventing pins raised to the lane from falling down on the lane; and a retracting mechanism for retracting the pin guide from the lane.

Thus, in the first aspect of the present invention, the pins disposed on the lane can be prevented from falling down.

In a second aspect of the present invention, the bottle lifter includes a plurality of cylindrical cylinders for loading the pins in an upright state, and a lifting mechanism for lifting the cylinders, and a loading port for loading the pins is provided in a side surface of the cylinders.

Thus, in the second aspect of the present invention, the jar can be filled with the pins in a short time.

That is, in the present invention, since the cylinder portion is raised and the pins are arranged on the lane, if the filling port is provided at the upper portion of the cylinder portion as described in japanese patent application laid-open No. 2002-119634, the next ball filling pin must be kept on standby at a standby position that is shifted from the filling port in order to prevent interference between the pins (next ball filling pin) to be filled into the cylinder portion when the cylinder portion is raised.

Therefore, in the invention disclosed in japanese patent application laid-open No. 2002-119634, when the ball bottle is loaded into the cylinder portion, the ball bottle for the next loading must be moved from the standby position to the loading port, and therefore, the ball bottle cannot be directly loaded into the cylinder portion even if the cylinder portion is lowered.

In contrast, in the second aspect of the present invention, since the filling port is provided on the side surface of the cylinder portion, the next filling pins to be ready for the next filling operation do not have to wait at a position shifted from the filling port.

Therefore, at the next filling operation, the pins do not need to be moved from the standby position to the filling port, and the pins can be filled into the cylinder portion substantially simultaneously with the lowering of the cylinder portion, so that the pins can be filled into the cylinder portion in a short time.

In the third aspect of the present invention, a piston portion displaceable in the cylinder portion is provided in the cylinder portion, and after the cylinder portion and the piston portion are integrally raised by a predetermined amount, only the piston portion is raised, and the pins are pushed up onto the ball way from a hole portion provided in the ball way.

Thus, the pins can be raised to the vicinity of the lane while being prevented from falling down by the cylinder portion, and then only the pins can be raised to the lane by the piston portion.

Further, the hole portion of the ball path is preferably closed by the piston portion as described in the fourth aspect of the present invention.

In addition, in a fifth aspect of the present invention, a piston portion includes: a base part which contacts with the ball bottle and closes the hole part; and a first elastic deformation portion that transmits the lifting force of the lifting mechanism to the base portion and is elastically deformable in the displacement direction of the piston portion.

Thus, dimensional variations in the lifting mechanism and the base portion, dimensional variations in assembly, and the like can be absorbed by the first elastically deformable portion.

Further, as described in the sixth aspect of the present invention, the pin guide preferably includes a holding portion for holding the pin.

Further, as described in the seventh aspect of the present invention, the pin guide is preferably provided with a detection device for detecting the presence or absence of a pin.

In the eighth aspect of the present invention, the escape mechanism switches between a case where the pins are prevented from falling down by the pin guide and a case where the pin guide is evacuated from the lane by displacing the pin guide in the vertical direction, and further includes a second elastic deformation portion that connects the escape mechanism side and the pin guide and is elastically deformable in the vertical direction.

Thus, in the eighth aspect of the present invention, the vial guide can be reliably displaced in the vertical direction.

That is, when the pin guide descends in a state where the pins are tilted, the pin guide interferes with the tilted pins, and the pin guide cannot be completely lowered, thereby adversely affecting the lowering operation of the other pin guide.

In contrast, in the eighth aspect of the present invention, even if the toppled pins interfere with the pin guide, the second elastically deforming portion can absorb the interference, and thus the lowering operation of the other pin guide can be prevented from being adversely affected.

In addition, the bowling game apparatus may have the following features.

First, the number of parts of the bottle setting machine can be reduced to realize a simple configuration.

Therefore, the bowling game apparatus adapted to allow a player to roll a ball toward a plurality of pins arranged upright on a lane and to tilt the plurality of pins arranged upright is used for a pin setter for arranging the pins at a predetermined position, and preferably includes a dispenser for guiding the pins to the predetermined position while sliding down the pins.

Thus, since the dispenser guides the pins to the predetermined position while sliding down, the number of parts of the pin setter is reduced and the structure can be simplified as compared with a structure in which the pins are arranged at the predetermined position one by an arm that expands and contracts while swinging.

Preferably, the ball supply device further includes a supply device for supplying the same number of the dispensers as the number of the bottles arranged upright on the lane, and the supply device is capable of simultaneously supplying the bottles to the plurality of the dispensers.

Thus, since a plurality of pins can be arranged in a short time, the processing speed of the pin setter can be increased.

As a specific structure capable of simultaneously supplying the pins to the plurality of dispensers, it is preferable that the pin supply ports of the plurality of dispensers are arranged substantially on a straight line, and the supply device supplies the pins to the plurality of supply ports, respectively, in a state where the plurality of pins are arranged substantially on a straight line, as in the present embodiment.

Further, it is preferable to reduce the number of parts of the collecting mechanism for collecting the pins and balls, and to form a simple structure.

Therefore, the collecting mechanism for collecting the pins and the balls has the following structure.

The recovery mechanism is suitable for a bowling game device in which a player rolls a ball to a plurality of pins vertically arranged on a ball path to tilt the plurality of pins vertically arranged, and is used for recovering the pins and the ball, and comprises: a pin recovery mechanism having a rotating body that rotates, and configured to recover pins by rotation of the rotating body; and a conveyor for conveying the pins that have reached the terminal end side of the lane and the pins that have been swept out at the terminal end side of the lane to the pin collection mechanism, wherein a pin transfer portion for transferring the pins and a ball transfer portion for transferring the balls are provided on the rotating body.

Thus, the number of parts of a ball collecting mechanism for collecting the pins and balls can be reduced, and a simple structure can be realized.

Preferably, the rotating body is formed in a substantially plate shape, and a side surface perpendicular to a rotation axis of the rotating body intersects with a horizontal surface, the pin transfer portion is provided on an outer peripheral side of the ball transfer portion in the rotating body, a distance between an end portion of the transporting device on the pin collecting mechanism side and the rotating body is set to be smaller than a diameter of the ball and larger than a maximum diameter of the pin, and the end portion of the transporting device on the pin collecting mechanism side is set to be located higher than an upper end of the pin transfer portion and lower than the upper end of the ball transfer portion in a vertical direction.

Thus, the pins fall from the gap between the pin transfer device and the pin collection mechanism and are stored in the pin transfer unit, and the balls are not dropped from the gap but are stored in the ball transfer unit.

Therefore, even if the pins and the balls are conveyed to the pin collection mechanism in a mixed state, the pins and the balls can be collected separately.

The phrase "the side surface perpendicular to the rotation axis intersects the horizontal plane" also includes any of the case where the side surface of the rotating body is made vertical and the case where the side surface is inclined with respect to the horizontal plane.

The ball transfer part is preferably formed of a concave portion that is recessed from a side surface of the rotating body in a direction parallel to the rotation axis, and the side surface is inclined with respect to a horizontal plane such that an opening of the concave portion is open upward.

Thus, the bottom and inner peripheral side surfaces of the recess can hold the ball. On the other hand, if the side surface of the rotating body is vertical, the ball needs to be held only by the inner peripheral side surface of the recess, and therefore the depth (depth) of the recess needs to be increased.

Therefore, the thickness of the rotating body can be reduced as compared with the case where the side surface of the rotating body is vertical.

A ball collecting part for taking out the balls filled in the concave part is arranged on the upper side of the lowest part of the rotating body.

Preferably, the recess is formed by a through hole penetrating the rotating body, a fixing plate for closing the through hole constituting the recess is provided, and the fixing plate is provided with a hole forming the ball collecting portion.

In addition, a pin recovery mechanism capable of recovering pins at high speed can be provided.

Therefore, the recovery mechanism may have the following configuration.

The collecting mechanism is suitable for a bowling game device in which a player rolls a ball to a plurality of pins arranged upright on a lane and topples over the plurality of pins arranged upright, and the collecting mechanism collects the pins and conveys the pins to a pin setter for arranging the collected pins at a predetermined position, and the collecting mechanism includes: a first conveying device for conveying the pins swept out to the terminal side of the lane; a rotating body, which is provided with a ball bag part for containing the ball bottles conveyed by the first conveying device on the outer circumference side, and the rotating shaft of the rotating body is inclined relative to the horizontal direction; a fixed plate which closes the ball bag portion from a portion side of the rotating body facing downward and is provided with a long-hole shaped irregular slit extending in a rotating direction of the rotating body on an upper side; and a second conveying device for conveying the pins dropped from the irregular slit to the pin setter, wherein a dimension in a short diameter direction of the first hole portion on a retreating side in a rotational direction in the irregular slit is larger than a dimension in a diameter direction of the small diameter portion of the pin and smaller than a dimension in a diameter direction of the large diameter portion of the pin, and a dimension in a short diameter direction of the second hole portion on an advancing side in the rotational direction in the irregular slit is larger than a dimension in a diameter direction of the large diameter portion of the pin.

Thus, when the pin reaches the irregular slit in a state where the small diameter portion side of the pin is located on the forward side in the rotational direction of the rotating body, the small diameter portion reaches the first hole portion and falls from the first hole portion in a state where the large diameter portion is engaged with the first hole portion, so that the small diameter portion descends and the large diameter portion ascends to rotate the pin.

That is, in a state where the pins are accommodated in the pocket portions, the pins are conveyed to the side of the irregular slit in a state where their central axes are inclined with respect to an imaginary contact surface that connects the contact portion of the large diameter portion and the inner wall of the pocket portion and the contact portion of the small diameter portion and the inner wall of the pocket portion. When the tip of the ball pin reaches the irregular slit, the wall supporting the small diameter portion disappears, and the small diameter portion reaches the first hole portion and drops from the first hole portion at about the same time, so that the small diameter portion faces downward and the large diameter portion faces upward, and the ball pin rotates.

At this time, the first hole portion, that is, the irregular slit is fixed by the fixing plate, and a force (braking force) for preventing the movement of the pins together with the rotating body is generated at a contact portion between the large diameter portion and the first hole portion (hereinafter, this contact portion is referred to as a braking point).

On the other hand, the bottom portion of the pin is pressed by the rotating body, and the bottom portion of the pin is rotated to the forward side in the rotational direction with the braking point as the rotational center, and the large diameter portion is positioned on the forward side in the rotational direction of the braking point. That is, the large diameter portion is positioned on the forward side in the rotation direction than the small diameter portion.

At this time, the pins receive a force in the forward direction from the rotating body at a position away from the braking point toward the bottom side, and move to the second hole portion in a state where the braking point receives a force in the backward direction from the rotating body (hereinafter, this state is referred to as a drop preparation state), and therefore the large diameter portion reaches the second hole portion earlier than the small diameter portion.

Therefore, when the large diameter portion reaches the second hole portion, the bulb is rotated such that the large diameter portion faces downward and the small diameter portion faces upward and falls.

On the other hand, when the pin reaches the irregular slit in a state where the large diameter portion side of the pin is located at the forward side position in the rotational direction of the rotating body, only the small diameter portion falls from the first hole, and the pin is in a fall ready state and moves to the second hole. Therefore, when the large diameter portion reaches the second hole portion, the large diameter portion of the bottle is directed downward and the small diameter portion is directed upward and falls as described above.

In this way, the moving direction of the pins is not reversed, and the pins are rotated and aligned in the same direction, so that the problem that the pins pass through the irregular slit due to the inertial force acting on the pins does not occur in principle.

Therefore, the recovery rate of the pins is not deteriorated, and the recovery rate of the pins can be increased.

Further, in the case where the small diameter portion is located on the forward side in the rotational direction and the pins are conveyed, the pins are moved to the second hole portion while the first hole portion is rotated to be in the drop ready state, and therefore, in the case where the small diameter portion is located on the forward side in the rotational direction and the pins are conveyed, the timing at which the pins drop from the second hole portion is almost the same as in the case where the large diameter portion is located on the forward side in the rotational direction and the pins are conveyed.

Therefore, in the first embodiment of the present invention, since the variation in timing when the pins collected by the pin collecting mechanism are conveyed to the pin setter can be reduced, malfunction of the pin setter can be prevented.

Preferably, a gap is provided between the rotating body and a portion of the fixed plate where the irregular slit is provided.

Accordingly, the distance between the braking point and the portion of the contact portion between the pins and the rotating body that receives the force for moving the pins can be increased, and therefore the torque required to rotate the pins to the drop-ready state can be increased in a state where the smaller diameter portion of the pins is located on the forward side in the rotational direction of the rotating body.

Therefore, since the pins are moved to the second hole portion in a state where the pins are surely in the drop ready state, the recovery rate of the pins is not deteriorated, and the recovery rate of the pins can be increased.

Preferably, the ball bottle further includes a blocking means for blocking the movement of the tip end side of the ball bottle dropped from the first hole portion in accordance with the rotation of the rotating body.

Thus, the tip end of the ball bottle can be reliably prevented from moving together with the rotating body, and the ball bottle can be reliably rotated to be in the drop ready state.

Preferably, in a state where the tip end side of the ball pin is dropped from the first hole, the upper outer edge portion of the first hole contacts the ball pin, and the lower outer edge portion of the first hole is in a non-contact state with the ball pin.

Thus, the upper pins contact the upper outer edge of the first hole with the center axis of the pins, the lower pins contact the rotary body with the center axis, and the contact portion with the rotary body is located closer to the bottom side than the braking point (the contact portion between the outer edge of the first hole and the pins).

Therefore, the pins in the ready-to-drop state can be prevented from dropping to the side opposite to the direction in which the pins should originally drop, that is, the side opposite to the fixed plate with the rotating body interposed therebetween, and therefore the pins can be reliably moved to the second hole in the ready-to-drop state. Therefore, the recovery rate of the pins is not deteriorated, and the recovery rate of the pins can be increased.

Further, although the present invention and various features related thereto have been described, when a combination of problems corresponding to these features occurs, the problems can be solved by combining a plurality of features.

In the following description, the pin transfer mechanism 200 and the pin setter 300 are distinguished as different mechanisms, and this is for ease of understanding the bowling game apparatus 1 according to the present embodiment.

That is, the classification of the mechanisms constituting the bowling game device 1 is not limited to the following description, and for example, the pin conveying mechanism 200 and the pin setter 300 may be classified into one mechanism (pin setter).

As shown in fig. 24, the operations of the collection mechanism 100, the vial conveying mechanism 200, the vial placing machine 300, and the sweeping mechanism 400 are controlled by a control circuit 500, and the control circuit 500 is formed by a microcomputer including a CPU, a ROM, a RAM, and the like. Then, the control circuit 500 controls the recovery mechanism 100 and the like in accordance with a program stored in a nonvolatile storage device such as a ROM.

3. Recovery mechanism 100

As shown in fig. 1, the collecting mechanism 100 is a pin collecting mechanism that simultaneously collects the toppled pins P and the balls B that have reached the terminal end side of the lane 3. The pins P collected by the collection mechanism 100 are conveyed to the pin placing machine 300 via the pin conveying mechanism 200, and the balls B are conveyed to one end side of the lane 3 via the return projector 106 provided on the lower side of the lane 3.

The collecting mechanism 100 includes a collecting unit 110 formed of a rotating body 111 or the like, a conveyor 101 disposed between the collecting unit 110 and the lane 3, a pin projector 103 that guides collected pins P to the pin conveying mechanism 200, and a ball projector 105 that guides collected balls B to a return projector 106 (see fig. 3).

The conveyor 101 is a device that conveys the balls B that have reached the terminal end side of the lane 3 and the pins P that have been swept out to the terminal end side of the lane 3 to the recovery mechanism 100 by an endless belt that is rotationally driven by an electric motor.

The pin projector 103, the ball projector 105, and the return projector 106 are guide devices that guide the pins P or the balls B to predetermined positions by sliding the pins P or the balls B down by the difference in height.

The ball shooter 103 is a flexible tube and is constituted by a flexible tube or a flexible guide groove, and the ball shooter 105 and the return shooter 106 may be flexible tubes, rigid tubes, flexible guide grooves, or rigid guide grooves.

The impact plate 107 is an impact member that causes the rolled ball B to impact and drop down onto the conveyor 101, the sweep plate 401 is a member that sweeps the pins P and the ball B toward the conveyor 101, and the sweep plate 401 is moved from the right side to the left side in fig. 1 by the sweep mechanism 400.

3.1 recovery section

As shown in fig. 2, the collecting unit 110 includes a rotating body 111 that rotates, a fixed plate 120 fixed to a frame (not shown) of the bowling game device 1, a housing 130 covering a lower end side of the rotating body 111, a motor 140 (see fig. 9 a) that rotates the rotating body 111, and the like.

The rotating body 111 is formed in a substantially plate shape as shown in fig. 9a, and a side surface 111B perpendicular to the rotation axis 111A is inclined so as to intersect with a horizontal plane, and on the outer peripheral side thereof, as shown in fig. 2, a plurality of protrusions 112 are provided at equal intervals in the circumferential direction so as to protrude radially outward.

A pin transfer portion (hereinafter, the recess 112A is referred to as a ball pocket portion 112A) for receiving the pins P conveyed by the conveyor 101 is configured by the recesses 112A formed between the protrusions 112, and the pins P are transferred to a deformed slit 121 described later by rotation of the rotating body 111 in a state where the pins P are received in the ball pocket portion 112A.

As shown in fig. 9a, a through hole 113 is provided in the rotating body 111 on the inner peripheral side with respect to the pocket 112A, and is recessed from the side surface 111B of the rotating body 111 in a direction parallel to the rotation axis 111A so as to penetrate the rotating body 111, and the opening of the through hole 113, which opens downward, is closed by the fixing plate 120.

On the other hand, the opening of the through-hole 113 that opens upward is open at the terminal end side of the conveyor belt 101, and the through-hole 113 is a concave portion whose lower side is closed. Therefore, the ball B conveyed by the conveyor 101 falls down to the through-hole 113 (hereinafter, the through-hole 113 is referred to as a concave portion 113) and is accommodated in the concave portion 113 (see fig. 9B).

Therefore, when the rotating body 111 rotates, the ball B accommodated in the recess 113 is transferred together with the pins P accommodated in the pocket portion 112A. That is, the concave portion 113 functions as a ball transfer portion for transferring balls.

As shown in fig. 9a, a guide plate 131 protruding from the housing 130 toward the conveyor belt 101 is provided between the conveyor belt 101 and the rotating body 111, and a gap between the guide plate 131 and the conveyor belt 101 is set to a size that does not interfere with the conveyor belt 101 when the belt 101 is operated.

Therefore, the pins P and the balls B conveyed by the conveyor 101 slide on the guide plate 131 and reach the pocket 112A or the recess 113. In the present embodiment, the conveyor 101 and the guide plate 131 constitute a conveying device that conveys the ball B that has reached the terminal end side of the lane 3 and the pins P that have been swept out to the terminal end side of the lane 3 to the collecting mechanism 100.

The distance W between the end 101A of the guide plate 131 on the recovery portion 100 side and the rotating body 111 is set to be smaller than the diameter of the ball B and larger than the maximum diameter of the pin P. The end 101A of the guide plate 131 is set higher than the upper end 112B of the pocket 112A and lower than the upper end 113A of the recess 113 in the vertical (up-down) direction.

As shown in fig. 2, the cover 130 covers only the pocket portion 112A located at least on the lowermost end side from the conveyor 101 side, and the pocket portion 112A located on the lowermost end side is a pocket open from the upper side.

The cover 130 prevents the pins P falling from the conveyor 101 to the pocket 112A from falling off from the pocket 112A, and prevents a plurality of pins P from entering one pocket 112A.

Further, since the cover 130 completely covers only the pocket 112A and the recess 113 is not completely covered by the cover 130, the ball B carried by the conveyor 101 slides on the guide plate 131 and is accommodated in the recess 113 without entering the pocket 112A.

In the present embodiment, as shown in fig. 2, 4a and 4b, a ring-shaped cover ring 132 covering the outer periphery of the rotating body 111 is integrally formed on the cover 130, and the cover ring 132 prevents the pins P accommodated in the pocket portions 112A from being projected in the radial direction by the inertial force (centrifugal force) of the rotation of the rotating body 111

In the present embodiment, the guide plate 131 is assembled as another component to the upper end portion 130A of the housing 130 (see fig. 4a and 4 b), but the present embodiment is not limited thereto, and the guide plate 131 may be integrally formed with the housing 130.

The fixing plate 120 is disposed on the lower surface side of the rotating body 111 to close the pocket 112A, and a long-hole shaped irregular slit 121 extending in the rotation direction of the rotating body 111 is provided on the upper side of the fixing plate 120, as shown in fig. 2.

The irregular slit 121 has a shape in which two kinds of long holes having different sizes in the short-diameter direction are connected in the long-diameter direction, as shown in fig. 8 a. Specifically, the short-diameter dimension a of the first hole 121A on the rotationally retreating side (right side in fig. 8 a) of the shaped slit 121 is set to be larger than the diameter dimension D1 (see fig. 8 b) of the small-diameter portion P1 of the pin P and smaller than the diameter dimension D2 (see fig. 8 b) of the large-diameter portion P2 of the pin P.

On the other hand, the short radial dimension B of the second hole 121B on the forward side in the rotational direction (left side in fig. 8 a) of the shaped slit 121 is set to be larger than the diameter dimension D2 of the large diameter P2 of the pin P. Therefore, only the small diameter portion P1 of the pin P can pass through the shaped slit 121 in the first hole 121A, the large diameter portion P2 is locked in the first hole 121A, and the entire pin P can pass through the shaped slit 121 in the second hole 121B.

Further, in the fixed plate 120, as shown in fig. 6, a gap 122 is provided at least between a portion where the irregular slit 121 is provided and the rotating body 111, and on the other hand, a funnel-shaped guide member 123 is provided on the fixed plate 120 on the side opposite to the gap 122, and the pins P dropped from the irregular slit 121 are guided to the pin shooter 103.

As shown in fig. 5, the guide member 123 has a receiving surface 123A provided in a portion corresponding to the first hole 121A, receives the pin P by coming into contact with the tip end side (the small diameter portion P1 side) of the pin P passing through the first hole 121A, and has an inclined guide surface 123B provided in a portion corresponding to the second hole 121B and inclined so as to descend downward toward the forward side (the right side in fig. 5) in the rotational direction of the rotating body 111.

The discharge port 123C communicating with the pin projector 103 is provided at the lowest position of the inclined guide surface 123B. In the present embodiment, as viewed in the horizontal direction, center line L1 of discharge port 123C is shifted toward the forward side in the rotational direction (the right side in fig. 5) with reference to curvature center O1 on the forward end side in the rotational direction of second hole 121B.

The receiving surface 123A is formed on a flat surface extending in the horizontal direction, and an abutting body 123D having a wall surface substantially parallel to the rotation direction of the rotating body 111 is provided on the boundary portion side between the receiving surface 123A and the inclined guide surface 123B.

Therefore, the distal end side of the vial P dropped from the first hole 121A engages with the resisting body 123D as shown in fig. 6. That is, the resisting body 123D serves as an obstacle means for preventing the distal end side of the pins P falling from the first hole 121A from moving integrally with the rotation of the rotating body 111.

As shown in fig. 6, in the arrangement relationship of the first hole 121A, the pocket portion 112A, and the receiving surface 123A, when the tip end side of the pin P is dropped from the first hole 121A, the upper outer edge 121C of the first hole 121A contacts the pin P, and the lower outer edge 121D of the first hole 121A and the pin P are in a non-contact state.

Therefore, in a state where the tip end side of the pin P is dropped from the first hole 121A, the upper pin P contacts the outer edge 121C of the first hole 121A via the center axis line L2 of the pin P, the lower pin P contacts the rotor 111 via the center axis line L2, and the contact portion 111C contacting the rotor 111 is located closer to the bottom side of the pin P than the contact portion 121E of the outer edge of the first hole 121A and the pin P.

As shown in fig. 11, a cover 124 for closing the shaped slit 121 is provided on the guide member 123 side of the shaped slit 121, and the cover 124 is driven to be opened and closed by a motor 124B via a link mechanism 124A.

As shown in fig. 8a, a long hole-shaped recovery hole 125 is provided in the fixed plate 120 at a position higher than the lowermost portion of the rotating body 111 and lower than the irregular slit 121, and the ball B received in the concave portion 113 and transferred is taken out from the lower surface side of the rotating body 111, and a ball recovery portion is formed by the recovery hole 125. The ball projector 105 (see fig. 1) is mounted on the fixing plate 120 at a position corresponding to the recovery hole 125.

4. Ball bottle conveying mechanism

As shown in fig. 1, the pin transfer mechanism 200 includes a distribution mechanism 210 configured to distribute pins P in a horizontal direction by 10 pins in a group, a transfer unit 230 configured to transfer pins P aligned by the distribution mechanism 210 to a distributor 250, and the distributor 250 configured to guide and transfer the pins P to a predetermined position of a pin setter 300 described later.

4.1 dispensing mechanism 210

The distributing mechanism 210 is a mechanism for arranging the pins P in a straight line on the conveyor belt 231 of the conveyor unit 230 by reciprocating in the horizontal direction on the outlet side of the pin shooter 103.

Specifically, as shown in fig. 14a and 14b, the projector includes a projector fixing section 201 to which the outlet side of the pin projector 103 is fixed, a mounting nozzle 202 for mounting the pins P discharged from the pin projector 103 on a conveyor belt 231, a rail 203 for supporting the projector fixing section 201 and the mounting nozzle 202 in a parallel movable manner, a drive belt 204 for connecting the projector fixing section 201 and the mounting nozzle 202, and a motor 205 for rotating the drive belt 204.

The mounting nozzle 202 is provided with a sensor (not shown) for detecting whether or not the pin P passes through the nozzle 202, and when the sensor detects the passage of the pin P, the motor 205 rotates the drive belt 204 to move the projector fixing section 201 and the mounting nozzle 202 in parallel.

In the present embodiment, the inlet side (guide member 123 side) of the pin projector 103 is fixed to the guide member 123 without movement, whereas the outlet side of the pin projector 103 reciprocates in the longitudinal direction of the rail 203.

On the other hand, since the 10 pins P placed on the conveyor belt 231 must be placed in parallel with the conveying direction of the conveyor belt 231 with their tips located downward, it is preferable that the outlet of the placing nozzle 202 always be oriented in parallel with the conveying direction of the conveyor belt 231.

Here, in the present embodiment, the placement nozzle 202 moves on the rail 203 with its outlet direction always oriented in a direction parallel to the conveying direction of the conveyor belt 231, and the projector fixing section 201 can move on the rail 203 while swinging about the swing fulcrum 201A as a swing center, and the dimension a of the placement nozzle 202 on the inlet side is larger than the dimension C of the bottle projector 103 on the outlet side.

The dimension a of the inlet side of the mounting nozzle 202 is larger than the dimension B of the outlet side of the mounting nozzle 202, in addition to (in consideration of) the dimension C of the outlet side of the pin projector 103, by the swing dimension of the projector fixing section 201.

In the present embodiment, the discharge direction of the pins P discharged from the pin shooter 103 is smoothly diverted and made parallel to the conveying direction of the conveyor belt 231 by smoothly reducing the size of the space between the inner walls from the inlet side to the outlet side of the placement nozzle 202.

4.2 transport Unit

The conveying unit 230 is a supply device that conveys 10 pins P aligned in a horizontal direction orthogonal to the conveying direction (the rotation direction of the conveying belt 231) to the upper side by rotating the conveying belt 231, and then supplies the pins P to the dispenser 250.

As shown in fig. 15, engagement protrusions 232 protruding outward are provided at a plurality of positions on the outer peripheral surface side of the conveyor belt 231, and the pins P placed on the conveyor belt 231 by the distribution mechanism 210 are conveyed upward in an engaged state by the engagement protrusions 232 (see fig. 1).

Further, as shown in fig. 16, a plurality of guide pieces 233 are provided on the upper surface side of the conveying unit 230 so as to prevent the pins P during conveyance from being excessively inclined with respect to the conveying direction, and these guide pieces 233 extend from one end side to the other end side in the longitudinal direction of the conveying unit 230 as shown in fig. 15.

On the other end side (right end side in fig. 15) in the longitudinal direction of the guide piece 233, a guide portion 234 is provided, which is curved along the outer peripheral surface of the driven roller 235 and guides the conveyed pins P to the pin supply port 251 of the dispenser 250.

The driving roller 236 rotates the conveying belt 231, and the driving roller 236 is rotated by a driving force from a motor 237 via a power transmission device such as a belt or a chain.

On the other hand, the driven roller 235 rotates with the rotation of the conveyor belt 231, the driven roller 235 is rotatably mounted on a tension lever 238, and the tension lever 238 is swingably mounted on the frame. Thus, the tension of the conveyor belt 231 is adjusted by the tension lever 238.

5. Bottle placing machine

The pin setter 300 is a mechanism for disposing a plurality of pins P conveyed by the pin conveying mechanism 200 at predetermined positions on the lane 3. Specifically, as shown in fig. 1, the dispenser 250, the bottle lifter 301, the bottle guide lifting mechanism 350, and the like are included.

5.1 liter bottle device

The bottle lifter 301 is a device for lifting the standing pins P up to the lane 3, as shown in fig. 1. Specifically, the device includes a plurality of cylindrical cylinder portions 302 for filling the bottles P in an upright state, a raising mechanism 340 for raising the cylinder portions 302, and the like.

5.1.1 lifting mechanism

The lifting mechanism 340 includes a lifting plate 341 to which 10 cylinders 302 arranged in a triangular (pyramid) shape are fixed, a chain 342 for lifting and lowering the lifting plate 341, a pulling-up machine 343 for pulling up the chain 342, and the like.

The chain 342 has one end fixed to the lifting plate 341 and the other end fixed to a fixed member such as the pulling-up unit 343, and the pulling-up unit 343 is provided with an arm 344 rotationally driven by a motor (not shown), a movable sprocket 345 rotatably attached to the tip end of the arm 344 and meshing with the chain 342, and the like.

The pair of idler sprockets 346 are rotatably fixed to a fixing member such as the upper puller 343, which imparts a predetermined tension to the chain 342 in order to prevent the chain 342 from falling off the movable sprocket 345.

The arm 344 rotates, the movable sprocket 345 moves in the direction of a → b → c → d → a or the opposite direction to that of fig. 1, and the rising plate 341 rises and falls at a speed 2 times as fast as the rotation of the arm 344, thereby raising and lowering the cylinder portion 302.

5.1.2 jar parts

As shown in fig. 17a, the cylinder portion 302 includes a first cylinder 303 that moves up and down together with a lifting plate 341, a second cylinder 304 that is disposed coaxially with the first cylinder 303 on the upper end side of the first cylinder 303 and is fixed to a fixing member such as a frame, and a piston portion 320 that displaces in the longitudinal direction of the first cylinder 303 in the first cylinder 303.

As shown in fig. 18, a first protrusion 305 protruding inward is provided on the inner wall of the first cylinder 303, and the upper end side of the first coil spring 306 engages with the first protrusion 305. On the other hand, the lower end side of the first coil spring 306 is fixed to the rising plate 341. Therefore, the first cylinder 303 is connected to the rising plate 341 in a state supported by the rising plate 341 via the first coil spring 306.

The piston portion 320 includes a base portion 321 that contacts the bottom of the ball pin P to support the ball pin P from below, a push rod 322 that is fixed by being attached to the rising plate 341, and an elastically deformable second coil spring 323 that is disposed between the push rod 322 and the base portion 321.

The holding member 324 is a member detachably attached and fixed to the upper end side of the push rod 322 via a coupling member such as a bolt 324B, and the base portion 321 is connected to the push rod 322 via a bolt 325 movably inserted through a through hole 324A provided in the holding member 324.

Therefore, when the push rod 322 is raised, the rising displacement (rising force) of the push rod 322 (rising plate 341) is transmitted to the base portion 321 via the second coil spring 323, and conversely, when the push rod 322 is lowered, the lowering displacement (lowering force) of the push rod 322 (rising plate 341) is transmitted to the base portion 321 via the bolt 325.

As shown in fig. 17a, a second protrusion 307 protruding outward is provided on the outer wall of the lower end side of the first cylinder 303, and a stopper 308 is provided on the lower end of the second cylinder 304, so that when the first cylinder 303 is lifted, the lifting of the first cylinder 303 is mechanically restricted by the impact of the second protrusion 307.

A charging port 309 is provided on a side surface of the second cylinder 304, and is used for charging the first cylinder 303 (cylinder portion 302) with the pins P guided to the cylinder portion 302 via the dispenser 250, and the pins P charged into the cylinder portion 302 from the charging port 309 are accommodated in the first cylinder 303 in a state of standing on the base portion 321.

On the terminal side of the ball way 3, a hole portion 3A for pressing the pin P upward is provided at a portion corresponding to each cylinder portion 302 as shown in fig. 17b, and when the pin P is pushed up to the ball way 3, the hole portion 3A is closed by the base portion 321 as shown in fig. 17 c.

That is, when the first cylinder 303 is lifted from the lowered state (the state shown in fig. 17 a) to the lifting plate 341, the first coil spring 306 and the rod 322 are lifted at the same time, and the second protrusion 307 and the stopper 308 collide with each other as shown in fig. 17b, so that the first cylinder 303 and the piston portion 302 are lifted integrally with each other

When the second protrusion 307 strikes 8 against the stopper 30, the first coil spring 306 contracts and deforms, and the first cylinder 303 stops rising, whereas the plunger 322 rises integrally with the rising plate 341, and as shown in fig. 17c, the piston 320 rises in conjunction with the rising plate 341, and the base 321 fills the hole 3A.

At this time, although the dimensions of the respective portions are set such that the rising plate 341 stops rising in a state where the base portion 321 is filled in the hole portion 3A, there is a possibility that the rising plate 341 continues rising after the base portion 321 is filled in the hole portion 3A due to dimensional variations within the dimensional tolerance.

However, in the present embodiment, when the rising plate 341 continues to rise, this portion is absorbed by the second coil spring 323 (see fig. 17 d), and excessive rising force is prevented from acting on the ball path 3 by the piston portion 320

5.2 Dispenser

The dispenser 250 is a dispensing device that drops 10 pins P conveyed by the conveying unit 230 and dispenses the dropped pins P to the filling ports 309 of the cylinder portion 302.

That is, as shown in fig. 13, the dispenser 250 has a structure in which 10 vial supply ports 251 arranged in a straight line are connected to 10 filling ports 309 arranged at positions lower than the vial supply ports 251 in a triangular manner, and in the present embodiment, the dispenser 250 is formed of a flexible tube or a rigid member having a groove shape.

The 10 pins P are conveyed to the supply port 251 by the conveyance unit 230 while being aligned, and thus the 10 pins P are supplied to the pin supply port 251 (distributor 250) substantially simultaneously.

5.3 guide lifting mechanism for ball bottle

As shown in fig. 19a and 19b, the pin guide raising/lowering mechanism 350 includes a pin guide 351 for preventing the pins P raised to the lane 3 from falling down on the lane 3, and a retracting mechanism 360 for retracting the pin guide 351 from the lane 3 (see fig. 1).

5.3.1 balloon guide

The pin guide 351 is a cup-shaped object covering the pin P from the tip end thereof as shown in fig. 19a, and includes a holding rod 352 for holding the pin P by pressing the pin P against the inner wall of the pin guide 351 and a pin sensor 358 as a detection means for detecting the presence or absence of the pin P by displacement due to contact with the tip end of the pin P.

As shown in fig. 22, the 10 pin bottle guide 351 is mounted in a triangular shape on a substantially pentagonal elevating plate 353.

That is, as shown in fig. 19B, the ring-shaped fixture 356 is fixed to the raising plate 353 by a bolt 356A, and the vial guide 351 is slidably inserted into the fixture 356 from above, and is engaged with the upper end surface 356B of the fixture 356 by a stepped projection 351A provided on the outer peripheral portion of the fixture 356.

The upper end side of the vial guide 351 is always pulled toward the lift plate 353 by the pair of coil springs 357.

Therefore, normally, the lift plate 353 and the vial guide 351 are lifted and lowered integrally as shown in fig. 21a, and when the vial P falls and the vial P is not filled in the vial guide 351 but interferes with the vial guide 351, the vial guide 351 is separated from the lift plate 353 and the vial guide 351 and the lift plate 353 are lowered, respectively, as shown in fig. 21 b.

A movable plate 354 movable in parallel with respect to the rising plate 353 is attached to the rising plate 353, an actuator 355 for displacing the movable plate 354 with respect to the rising plate 353 is attached to the rising plate 353, and each clamping rod 352 is connected to the movable plate 354.

When the movable plate 354 is displaced to the left side in fig. 22 with respect to the rising plate 353, the gripping lever 352 is separated from the vial P to release the gripping of the vial P as shown in fig. 23b, while when the movable plate 354 is displaced to the right side in fig. 22 with respect to the rising plate 353, the gripping lever 352 presses the vial P as shown in fig. 23a, and thus the vial P is gripped by the vial guide 351.

5.3.2 Ejection mechanism

The retraction mechanism 360 is a mechanism for raising and lowering the 10 pin guides 351. As shown in fig. 20, the pair of lift guides 361 are fixed to the lift plate 353 at their lower end sides, and as shown in fig. 21, guide sheaths 362 that slidably contact the outer periphery of the lift guides 361 and guide the lift of the lift guides 361 are fixed to the frame 4 at the upper side of the lift plate 353.

The upper end sides of the pair of elevating guides 361 are connected by a beam 363, and when the elevating guides 361 are elevated by the beam 363, the dimension between the pair of elevating guides 361 is maintained constant, and the elevating guides 361 are smoothly elevated.

One end side of the chain 364 is coupled to the raising plate 353 (see fig. 21), and the other end side of the chain 364 is fixed to the frame 4 (see fig. 1). The elevation plate 353 is elevated in the same manner as the elevation mechanism 340 described above.

6. General operation of bowling game device (ビリボ I (registered trademark))

Pins P and balls B knocked down by balls B rolled by the player or pins P and balls B swept out by the sweeping-out mechanism 400 are conveyed to the collecting mechanism 100 by the conveyor 101 as shown in fig. 9a to 9c and fig. 10a to 10c, and then the balls B and pins P are collected by the collecting mechanism 100.

The collected pins P are aligned in the same direction as when they fall from the irregular slit 121, and then guided to the carrying unit 230 via the pin projector 103, while the collected balls B rise to a position higher than the lowermost portion of the rotating body 111, and then guided to the return projector 106 via the ball projector 105.

The pins P supplied from the transfer unit 230 to the dispenser 250 are loaded in the first cylinder 303 and then raised above the lane 3. At this time, the pin guide 351 descends on the lane 3, and the raised pins P are loaded into the pin guide 351 from the lower side and are set on the lane 3.

When the hole 3A of the lane 3 is closed by the base part 31, the pin guide 351 is retracted upward from above the lane 3, and a game is again enabled.

7. Features of the bowling game device of the present embodiment

In the present embodiment, since the ball pocket portion 112A serving as a bottle transfer portion for transferring the pins P and the concave portion 113 serving as a ball transfer portion for transferring the balls B are provided in the rotating body 111, the number of components of the collecting mechanism 100 for collecting the pins P and the balls B can be reduced, and a simple structure can be provided.

In the present embodiment, the distance between the end 101A of the guide piece 131 of the conveying device that conveys the ball B that has reached the terminal end side of the lane 3 and the pin P that has been swept out to the terminal end side of the lane 3 to the collecting mechanism 100 and the rotating body 111 is smaller than the diameter of the ball B and larger than the maximum diameter of the pin P as shown in fig. 9 a.

Further, since the end portion 101A of the guide piece 131 is set at a position higher than the upper end 112B of the pocket portion 112A and lower than the upper end 113A of the recess 113 in the vertical direction, the pins P fall through the gap between the guide piece 131 and the recovery mechanism 100 (the rotating body 111) and are accommodated in the pocket portion 112A as shown in fig. 10a to 10c, while the balls B are accommodated in the recess 113 without falling through the gap as shown in fig. 9a to 9 c.

Therefore, even if the pins P and the balls B are conveyed to the collection mechanism 100 in a mixed state, the pins P and the balls B can be separated and easily collected.

In the present embodiment, as shown in fig. 9B, the recess 113 is formed of a recess recessed from the side surface 111B of the rotating body 111 in a direction parallel to the rotation axis 111A, and the side surface 111B is inclined with respect to the horizontal direction so that the opening of the recess 113 is opened upward, and therefore the ball B is held by the bottom portion 113B and the inner peripheral side surface 113C of the recess 113.

On the other hand, if the side surface 111B of the rotating body 111 is vertical, the ball B needs to be held only by the inner peripheral side surface 113C of the recess 113, and therefore the depth of the recess 113 has to be increased.

Therefore, in the present embodiment, the thickness of the rotating body 111 can be made thinner than in the case where the side surface 111B of the rotating body 111 is vertical.

In the present embodiment, the dimension a in the short diameter direction of the first hole portion 121A on the rotationally retreating side in the shaped slit 121 is set to be larger than the diameter dimension of the small diameter portion P1 of the pin P and smaller than the diameter dimension of the large diameter portion P2 of the pin P, and the dimension B in the short diameter direction of the second hole portion 121B on the rotationally advancing side in the shaped slit 121 is set to be larger than the diameter dimension of the large diameter portion P2.

Thus, in the present embodiment, when the pin P reaches the irregular slit 121 in a state where the side of the small diameter portion P1 of the pin P is positioned on the forward side in the rotational direction of the rotating body 111, as shown in fig. 5, the small diameter portion P1 reaches the first hole 121A, and the small diameter portion P1 falls from the first hole 121A in a state where the large diameter portion P2 is engaged with the first hole 121A, and therefore the small diameter portion P1 descends and the large diameter portion P2 ascends to rotate the pin P.

That is, in a state where the pins P are housed in the pocket 112A, as shown in fig. 25, the pins P are conveyed to the side of the irregular slit 121 in a state where the center axis L2 of the pins P is inclined with respect to a virtual contact surface S3 formed by connecting the contact portion S1 of the large diameter portion P2 and the inner wall of the pocket 112A and the contact portion S2 of the small diameter portion P1 and the inner wall of the pocket 112A.

In this state, when the tip of the pin P reaches the irregular slit 121, the wall supporting the small diameter portion P1 disappears, and as shown in fig. 5 and 6, the small diameter portion P1 reaches the first hole portion 121A substantially simultaneously with the small diameter portion P1 dropping from the first hole portion 121A, and therefore the small diameter portion P1 descends, the large diameter portion P2 ascends, and the pin P rotates.

At this time, since the first hole 121A, that is, the irregular slit 121 is provided in the fixed plate 120 without movement, a force (braking force) for preventing the pins P from moving together with the rotating body 111 is generated at a contact portion (braking point) between the large diameter portion P2 and the first hole.

On the other hand, since the bottom portion side of the pin P is pressed by the rotating body 111, the bottom portion of the pin P rotates to the forward side in the rotating direction with the above-mentioned braking point as the rotation center, and the large diameter portion P2 is located on the forward side in the rotating direction from the braking point. That is, the large diameter portion P2 is located on the forward side in the rotational direction with respect to the small diameter portion P1.

At this time, the pins P are located at positions shifted from the braking points toward the bottom side, and the pins P receive a force advancing in the rotational direction from the rotating body 111, and move to the second hole portion 121B in a state where the pins receive a force in the rotational direction retracting direction at the braking points (the drop preparation state), and therefore the large diameter portion P2 reaches the second hole portion earlier than the small diameter portion P1.

Therefore, when the large diameter portion P2 reaches the second hole 121B, the large diameter portion P2 of the pins P descends, the small diameter portion P1 ascends, and the pins rotate and fall.

On the other hand, when the pin P reaches the irregular slit 121 in a state where the large diameter portion P2 side of the pin P is located on the forward side in the rotational direction of the rotating body 111, only the small diameter portion P1 falls from the first hole 121A, and the pin P moves to the second hole 121B in the above-described drop preparation state. Therefore, when the large diameter portion P2 reaches the second hole portion 121B, the large diameter portion P2 of the pin P descends and the small diameter portion P1 ascends as described above, and the pin P falls.

As described above, in the present embodiment, the problem that the pins P pass through the irregular slit 121 due to the inertial force acting on the pins P is basically not caused because the moving direction of the pins P is not reversed and the pins P are aligned in the same direction by rotating the pins P.

Therefore, in the present embodiment, the recovery rate of the pins P can be increased without deteriorating the recovery rate of the pins P.

For example, in the invention described in japanese patent application laid-open No. 11-333044, when the small diameter portion P1 is located on the forward side in the rotational direction and the pins P are conveyed, the pins P fall down after the conveyance direction is reversed.

On the other hand, in the case where the large diameter portion P2 is located on the forward side in the rotational direction and the pins P are conveyed, the pins P fall down without reversing their conveyance direction, and even if the rotational speed of the rotary body 111 is constant, the period (timing) at which the pins P fall from the drop hole depends on the state of the pins P conveyed to the drop hole in the invention disclosed in japanese patent application laid-open No. 11-333044.

That is, in the invention disclosed in japanese patent application laid-open No. h 11-333044, when the small diameter portion P1 is located on the forward side in the rotational direction and the pins P are conveyed, the timing at which the pins P fall from the drop holes is later than when the large diameter portion P2 is located on the forward side in the rotational direction and the pins P are conveyed.

Therefore, in the invention disclosed in japanese unexamined patent application publication No. h 11-333044, the timing at which the pins P collected by the collection mechanism 100 are conveyed to the pin setter 300 varies, and therefore, malfunction of the pin setter 300 is likely to occur.

In contrast, in the present embodiment, when the small diameter portion P1 is positioned on the rotational direction forward side and the pins P are conveyed, the pins P rotate in the first hole 121A and are ready to fall, and the pins P move to the second hole 121B, so that the timing of dropping the pins P from the second hole 121B is almost the same when the small diameter portion P1 is positioned on the rotational direction forward side and the pins P are conveyed when the large diameter portion P2 is positioned on the rotational direction forward side.

Therefore, in the present embodiment, since the timing fluctuation when the pins P collected by the collection mechanism 100 are conveyed to the pin setter 300 is small, malfunction of the pin setter 300 can be prevented.

In the present embodiment, since the gap 122 is provided between the portion of the fixed plate 120 where the irregular slit 121 is provided and the rotating body 111, the distance between the portion of the contact portion between the pins P and the rotating body 111, which receives the force for moving the pins P, and the braking point can be increased.

Therefore, the moment required to rotate the pin P from the state in which the small diameter portion P1 side of the pin P is positioned on the forward side in the rotational direction of the rotating body 111 to the state ready for dropping becomes large, and the pin P is reliably moved to the second hole portion 121B in the state ready for dropping. Therefore, in the present embodiment, the recovery rate of the pins P is not deteriorated, and the recovery rate of the pins P can be increased.

In the present embodiment, since the resisting body 123D as a stopping member for stopping the movement of the tip end of the pin P falling from the first hole 121A is provided on the tip end side of the pin P as the rotating body 111 rotates, the tip end of the pin P can be reliably stopped from moving together with the rotating body 111, and the pin P can be reliably rotated to the state ready for falling.

In the present embodiment, in a state where the tip end side of the pin P is dropped from the first hole 121A, as shown in fig. 6, the pin P is brought into contact with the upper outer edge 121C of the first hole 121A on the upper side through the center axis L2 of the pin P, the pin P is brought into contact with the rotary body 111 on the lower side through the center axis L2 of the pin P, and the contact portion with the rotary body 111 is located closer to the bottom side of the pin P than the braking point (the contact portion between the outer edge of the first hole 121A and the pin P).

Therefore, the pins P in the ready-to-drop state can be prevented from dropping to the opposite side of the direction in which the pins P should drop, that is, to the opposite side of the fixed plate 120 across the rotating body 111, and therefore the pins P can be reliably moved to the second hole portions 121B in the ready-to-drop state. Therefore, the recovery rate of the pins P is not deteriorated, and the recovery rate of the pins P can be increased.

In the present embodiment, since the pins P are dropped from the dispenser 250 and guided to the predetermined position, that is, the triangular filling port 309 is arranged, the number of parts of the pin setter 300 can be reduced and the structure can be simplified, compared to the invention disclosed in japanese patent application laid-open No. 11-333044 in which the pins P are supplied to the predetermined position in a one-by-one manner by a swinging and expanding arm.

In the present embodiment, since the transfer unit 230 serving as a supply device for supplying the pins P to the dispenser 250 can simultaneously supply the pins P to the plurality of dispensers 250, a plurality of pins P can be supplied and arranged in a short time, and the processing speed of the pin setter 300 can be increased.

In the present embodiment, the pin guide 351 that prevents the pins P that have risen to the lane 3 from falling down on the lane 3 is provided, so that the pins P disposed on the lane 3 can be prevented from falling down.

In the present embodiment, since the filling port 309 for filling the pins P in the side surface of the cylinder portion 302 (second cylinder 304) is provided, the pins P can be filled in the cylinder portion 302 (first cylinder 303) in a short time.

That is, in the present embodiment, since the first cylinder 303 is raised and the pins P are arranged on the lane 3, if the filling port is located at the upper portion of the cylinder portion as described in japanese patent application laid-open No. 2002-119634, the next filling pin must wait at a standby position that is shifted from the filling port in order to prevent the pins (next filling pins) to be filled next in the cylinder portion from interfering with the cylinder portion when the cylinder portion is raised.

Therefore, in the invention disclosed in japanese patent application laid-open No. 2002-119634, when the ball bottle is loaded into the cylinder portion, the next ball bottle for loading must be moved from the standby position to the loading port, and therefore, even if the cylinder portion is lowered, the ball bottle cannot be loaded into the cylinder portion immediately.

In contrast, in the present embodiment, since the filling port 309 is provided on the side surface of the second cylinder 304, it is not necessary to wait for the next filling pins P to be positioned at a position offset from the filling port in preparation for the next filling operation of the pins P.

Therefore, in the next filling operation, it is not necessary to move the pins P from the standby position to the filling port 309, and the pins P for the next filling can be filled in the cylinder portion 302 (first cylinder 303) substantially at the same time as the first cylinder 303 is lowered, so that the pins P can be filled in the cylinder portion 302 in a short time.

In the present embodiment, since the first cylinder 303 is raised by a predetermined amount integrally with the piston 320, and then the piston 320 is operated to raise the pins P to push the pins P from the holes 3A provided in the lane 3 to the lane 3, the pins P are raised to the vicinity of the lane 3 while the pins P are prevented from falling down by the first cylinder 303, and then only the pins P are raised to the lane 3 by the piston 320.

In the present embodiment, since the second coil spring 323 as the elastic deformation portion is provided between the base portion 321 and the push rod 322, dimensional variations of the lifting mechanism 340 and the base portion 321, dimensional variations of assembly, and the like can be absorbed by the second coil spring 323.

In the present embodiment, the coil spring 357 is provided, and serves as an elastic deformation portion that can be elastically deformed in the vertical direction while connecting the retraction mechanism 360 side and the vial guide 351, so that the vial guide 351 can be reliably displaced in the vertical direction.

That is, when the pin guide 351 is lowered in a state where the pins P are tilted, the tilted pins do not interfere with the pin guide 351, so that the pin guide 351 cannot be completely lowered, and the lowering operation of the other pin guide 351 is adversely affected.

In contrast, in the present embodiment, as shown in fig. 21b, even if the toppled pins P interfere with the pin guide 351, the coil spring 357 can absorb the interference, thereby preventing the lowering operation of the other pin guide 351 from being adversely affected.

In the present embodiment, the pull-up mechanism 343 configured to raise and lower the rising plate 341 and the retracting mechanism 360 configured to raise and lower the rising plate 353 are configured by a crank mechanism utilizing the rotation of the arm, and therefore the displacement speed at the start and end of the displacement is reduced.

Therefore, at the start and end of the deformation, the large inertial force can be suppressed from acting on the rising plate 341 and the rising plate 353, and therefore the rising plate 341 and the rising plate 353 can be displaced smoothly.

(second embodiment)

In the first embodiment, the cover ring 132 is integrated with the cover 130, but in the present embodiment, the cover ring 132 is integrated with the rotating body 111 and has a shape that closes the outer peripheral side of the pouch portion 112A.

Thus, in the present embodiment, when the rotating body 111 rotates, the pins P stored in the pocket portion 112A are prevented from being transferred to the side of the irregular slit 121 while being wiped by the cover ring 132, so that noise generated when transferring the pins P can be reduced, and abrasion of the pins P and the cover ring 132 can be suppressed.

This embodiment can further improve the recovery rate of the pins in the recovery unit 110, and will be described below together with the drawings.

1. Characteristic structure of bowling game device of the present embodiment

In the present embodiment, as shown in fig. 26, the rotation center O1 side of the shaped slit 121 is enlarged beyond the bottom portion 112C of the pocket 112A to the rotation center O1 side, whereby the short radial direction dimension A, B (see fig. 27) of the shaped slit 121 is made larger than that of the above-described embodiment, and as shown in fig. 31b, a portion of the cover ring 132 corresponding to the shaped slit 121 is notched.

In the present embodiment, the substantial short-diameter direction dimension a1 (see fig. 26) of the first hole 121A formed by the rotating body 111 and the shaped slits 121 is about 0.9 times the diameter dimension D2 (see fig. 8B) of the large-diameter portion P2 of the pin P, and the substantial short-diameter direction dimension B1 (see fig. 26) of the second hole 121B formed by the rotating body 111 and the shaped slits 121 is about 1.1 times the diameter dimension D2 of the large-diameter portion P2 of the pin P.

As shown in fig. 28, the depth of the pocket 112A, i.e., the distance from the outer peripheral surface of the rotor 111 to the bottom 112C, is set so that the depth d1 on the forward side in the direction of rotation of the rotor 111 is greater than the depth d2 on the rear end side in the direction of rotation.

Therefore, in the present embodiment, of the side walls of the pocket portion 112A, the side wall 112D on the rotationally retreating side extends in a substantially parallel manner in the radial direction from the rotational center O1, while the side wall 112E on the rotationally advancing side extends in a substantially parallel manner in a direction substantially orthogonal to the bottom portion 112C.

As shown in fig. 29a and 29b, a recess 112F is provided in the side wall 112D on the retreating side in the rotational direction on the side of the fixed plate 120 on the side of the outer cover ring 132, and the recess 112F is set to a size that allows only the tip end portion of the pin P to be inserted.

That is, when the pin P is accommodated in the ball pocket portion 112A and the tip end side of the pin P is brought into contact with the side wall 112D on the retreating side in the rotational direction as shown in fig. 37a, the pin P is transferred to the irregular slit 121 in a state where the tip end side of the pin P is filled in the concave portion 112F as shown in fig. 37 b.

On the other hand, the bottom of the pin P contacts the side wall 112D on the backward side in the rotational direction, and when the pin P is stored in the pocket portion 112A, the bottom of the pin P is transferred to the irregular slit 121 without being filled in the recess 112F as shown in fig. 32.

As shown in fig. 30, a chamfered portion 113D is provided on the edge of the recess 113 for transferring the ball B on the opposite side of the fixed plate 120, and the substantial depth D3 of the recess 113 is made smaller than the thickness H of the rotating body 111 by the chamfered portion 113D. The substantial depth d3 of the concave portion 113 is a dimension of a portion of the inner peripheral side surface 113C of the concave portion 113 that acts on the retaining ball B.

As shown in fig. 40, a projection 120A projecting from the rotating body 111 is provided at a position of the fixing plate 120 corresponding to the pocket 112A and closer to the backward side in the rotating direction than the irregular slit 121, and in the present embodiment, the projection 120A is configured by attaching a bolt having a curved head such as a P-bolt to the fixing plate 120.

As shown in fig. 41, a stirring section 111D for stirring the plurality of pins P retained on the lower end side of the rotating body 111 is provided on the rotating body 111 on the opposite side of the fixed plate 120 from the fixed plate 120.

2. Features of the bowling game device of the present embodiment

In the present embodiment, since the substantial short-diameter direction dimension a1 of the first hole portion 121A constituted by the rotating body 111 and the irregularly shaped slit 121 is enlarged to about 0.9 times the diameter dimension D2 of the large-diameter portion P2 of the pin P, even when the bottom portion of the pin P is located on the backward side in the rotational direction and is accommodated in the pocket portion 112A, the pin P is transferred to the irregularly shaped slit 121, and the pin P is dropped in a state where the large-diameter portion P2 of the pin P is lowered to a position not more than the small-diameter portion P1.

That is, the bottom side of the pins P, which are located on the rotationally retreating side and housed in the pocket portion 112A, are transferred to the position where the irregular slit 121 is provided as shown in fig. 32 to 33a, and when the small diameter portion P1 of the pin P reaches the first hole portion 121A, the tip side of the pin P drops from the irregular slit 121 to the guide member 123 side and drops as shown in fig. 33 b.

At this time, the gap dimension a1 is enlarged to about 0.9 times the dimension D2 of the large diameter portion P2 of the pin P, and when the tip end side of the pin P starts to fall from the irregular slit 121 to the guide member 123 side, the pin P turns upside down with the large diameter portion P2 and the small diameter portion P1 becoming downside due to the gravity acting on the pin P, as shown in fig. 34a and 34 b.

When the rotor 111 is rotated in this state, a moment acts on the pins P, which is a moment that causes the large diameter portion P2 side of the pins P to be positioned on the forward side in the rotational direction than the small diameter portion P1 side, as shown in fig. 35a and 35b, due to the frictional force generated by the outer edge portion of the first hole 121A and the contact portion 121E (see fig. 34 b) with the pins P and the rotational force of the rotor 111.

Therefore, when the large diameter portion P2 of the pin P is transferred to the second hole 121B with the rotor 111 engaged with the outer edge of the first hole 121A and the large diameter portion P2 reaches the second hole 121B, the entire pin P drops from the irregular slit 121 to the guide member 123 and the large diameter portion P2 is located below the small diameter portion P1 and slides into the pin projector 103 as shown in fig. 36a and 36B.

Therefore, even if the pins P are transferred to the irregular slit 121 in a state where the bottom portions of the pins P are positioned on the rotationally retreating side and accommodated in the pocket portions 112A, the pins P can be reliably dropped in a state where the large diameter portions P2 of the pins P are positioned below the small diameter portions P1.

In a state where the tip end side of the pin P is positioned on the backward side in the rotation direction and is accommodated in the pocket portion 112A, as shown in fig. 37a and 37b, the pin P is transferred to the irregular slit 121 in a state where the tip end side of the pin P is filled in the concave portion 112F.

At this time, the tip end side of the pin P is fitted into the recess 112F provided on the cover ring 132 side in the side wall 112D on the backward side in the rotational direction, and the tip end side of the pin P is slidingly deformed to a portion deviated from the irregular slit 121 as shown in fig. 38.

Therefore, the small diameter portion P1 side of the pin P does not fall from the irregular slit 121 to the guide member 123 side, and when the large diameter portion P2 reaches the second hole portion 121B when the entire pin P moves along with the rotation of the rotating body 111, as shown in fig. 39a and 39B, the entire pin P falls from the irregular slit 121 to the guide member 123, and the large diameter portion P2 is located below the small diameter portion P1 and slides down in the pin shooter 103.

When the pins P are transferred to the irregular slit 121 in a state where the bottom side of the pins P is located on the backward side in the rotational direction and housed in the pocket portion 112A, the large diameter portion P2 of the pins P is located on the upper side and the small diameter portion P1 is located on the lower side as described above, but since the rotating body 111 is rotated all the time, the pins P jump and may vibrate in the arrow direction in a state where the tip side of the pins P drops to the first hole portion 121A as shown in fig. 34 b.

When the pins P bounce and vibrate, the cover ring 132 collides with the large diameter portion P2 of the pins P, and the pins P cannot reliably fall down to the guide member 123.

In contrast, in the present embodiment, since the cover ring 132 is cut out with a notch at a portion corresponding to the irregularly shaped slit 121, the cover ring 132 does not collide with the large diameter portion P2 of the pins P, and the pins P can be reliably dropped into the guide member 123.

In the present embodiment, since the cover ring 132 is prevented from colliding with the large diameter portion P2 of the pins P, the portion of the cover ring 132 corresponding to the shaped slit 121 is not notched, and the portion of the cover ring 132 corresponding to the shaped slit 121 is formed in a shape that is separated from the rotating body 111 and expands radially outward.

In the present embodiment, since the recess 112F into which the tip end of the pin P is inserted is provided in the side wall 112D on the retreating side in the rotational direction on the side of the fixing plate 120, the pin P can be stored in the pocket 112A in a stable state.

That is, as shown in fig. 8b, since the diameter of the pins P decreases from the large diameter portion P2 toward the bottom, when the force F acts on the bottom side from the large diameter portion P2 as shown in fig. 42, the tip end portions of the pins P float up from the state shown by the solid line to the state shown by the broken line.

Therefore, when another pin P strikes the bottom side of the large diameter portion P2 of the pin P stored in the pocket portion 112A, the tip end side of the stored pin P floats up from the fixed plate 120.

At this time, when the pins are accommodated in the pockets 112A and the tips of the pins P are positioned on the backward side in the rotational direction (see fig. 37a and b), since the pins P are supported on the tips of the pins P, the accommodated pins P fall from the pockets 112A when the tips of the pins P float from the fixed plate 120, and the recovery rate of the pins P decreases.

In contrast, in the present embodiment, since the concave portion 112F into which the tip end portion of the pin P is inserted is provided on the fixing plate 120 side in the side wall 112D on the backward rotation direction side, even if the other pins P are located closer to the bottom side than the large diameter portion P2, the tip end side of the pin P is prevented from floating from the fixing plate 120. Therefore, the stored pins P can be prevented from falling from the pocket portion 112A, and the lowering of the recovery rate of the pins P can be avoided.

Further, in a state where the bottom portion side of the pin P is positioned on the backward side in the rotational direction because the pin P is housed in the pocket portion 112A, even if the position of the impact of the other pin P is closer to the bottom portion side than the large diameter portion P2, the pin P hardly drops from the pocket portion 112A because the state of the pin P is stable.

If the depth of the concave portion 113 is sufficiently large, the pins P may be filled in the concave portion 113 and transferred. Here, in the present embodiment, since the chamfered portion 113D is provided on the edge of the recess 113 on the opposite side of the fixed plate 120, the substantial depth D3 of the recess 113 is smaller than the thickness H of the rotator 111, and the pins P can be prevented from being loaded into the recess 113 and transferred.

When the thickness H of the rotating body 111 is small, the chamfered portion 113D is not necessarily provided, but when the thickness H of the rotating body 111 is small, the pins P easily fall from the pocket portion 112A, and the pins P cannot be transferred to the irregular slit 121, so that the recovery rate of the pins P is lowered.

In contrast, although the problem can be solved by using the rotating body 111 having the thickness H on the outer peripheral side (bag portion 112A side) of the rotating body 111 different from the thickness H on the recess 113 side, in this solving method, the shape of the rotating body 111 becomes complicated, which leads to an increase in the manufacturing cost of the rotating body 111.

However, in the present embodiment, since the chamfered portion 113D is provided on the opposite side of the fixed plate 120 in the edge portion of the recess 113, the pins P can be prevented from being loaded into the recess 113 and transferred, and from falling from the pocket portion 112A, while suppressing an increase in the manufacturing price of the rotating body 111.

Even if the pins P stored in the incomplete state in the pocket portion 112A are transferred to the irregular slit 121, the pins P do not fall down from the irregular slit 121 as described above, and the pins P cannot be normally collected, resulting in a decrease in pin collection rate.

In contrast, in the present embodiment, since the fixing plate 120 is provided with the projection 120A at a position corresponding to the pocket 112A and is located on the retreating side in the rotational direction from the abnormal-shaped slit 121, the pins P stored in the pocket 112A in an incomplete state can be actively dropped from the pocket 112A before being transferred to the abnormal-shaped slit 112, and the recovery rate of the pins P can be improved.

That is, the pins P accommodated in the pocket part 112A in the complete state are in contact with the fixing plate 120 at two positions of the small diameter part P1 and the large diameter part P2. On the other hand, the pin P accommodated in the pocket part 112A in the incomplete state means a state in which only one of the small diameter part P1 and the large diameter part P2 of the pin P is in contact with the fixing plate 120.

Therefore, the pin P stored in the pocket portion 112A in an incomplete state has a high possibility that, for example, the tip end side of the pin P protrudes from the rotating body 111 to the opposite side (hereinafter referred to as the front side) of the fixed plate 120, and therefore, even when the pin P is transferred to the irregular slit 121, the pin P is highly likely not to fall from the irregular slit 121 as described above.

In contrast, in the present embodiment, since the projection 120A is provided, the pin P is pressed toward the front side by the projection 120A before the pin P reaches the irregularly shaped slit 121. Therefore, the pins P stored in the pocket part 112A in an incomplete state can be prevented from being sent to the irregular slit 121, and the recovery rate of the pins P can be improved.

Further, although the pins P stored in the pocket portion 112A in the complete state are also pressed toward the front surface side by the projection 120A, the pins P stored in the pocket portion 112A in the complete state are not dropped from the pocket portion 112A because they are in contact with the fixing plate 120 at two locations, i.e., the small diameter portion P1 and the large diameter portion P2.

When a plurality of pins P retained on the lower end side of the rotating body 111 are aligned, the retained pins P are less likely to enter the pocket portion 112A, and therefore the recovery rate of the pins P is lowered.

In contrast, in the present embodiment, since the stirring section 111D is provided on the front surface side of the rotating body 111, the plurality of pins P retained on the lower end side of the rotating body 111 are stirred by the stirring section 111D. Therefore, the plurality of pins P retained on the lower end side of the rotating body 111 can be prevented from being aligned in order, and the recovery rate of the pins P can be prevented from being lowered.

(fourth embodiment)

The present embodiment relates to a mounting structure of a holder for mounting various members to a bowling game device 1. Hereinafter, the present embodiment will be described by taking a case where the support 600 is attached to the side surface of the lane 3 in the bowling game device 1 as an example.

Fig. 43 is an external side view of the bowling game device 1. Fig. 44 is a cross-sectional view of the side frame 610 (fig. 43, a cross-sectional view taken along line 44-44). Fig. 45a is a front view of the bracket 600, fig. 45b is a side view of the bracket 600, and fig. 45c is a rear view of the bracket 600. Fig. 46 is an explanatory view of mounting of the bracket 600. Fig. 47 is a sectional view of the bracket 600 attached to the side frame 610, and is a sectional view taken along line 47-47 in fig. 43.

In the bowling game device 1, as shown in fig. 43, a side frame 610 extending in parallel with the longitudinal direction of the lane 3 is provided on the side surface of the lane 3, and as shown in fig. 44, a pair of opposing groove portions 611, 612 are provided at a predetermined interval from each other at a portion where the side frame 610 is attached to the holder 600.

In the present embodiment, the pair of groove portions 611 and 612 also extend in the same direction as the side frame 610, and both the groove portions 611 and 612 and the side frame 610 are integrally formed by performing extrusion processing or drawing processing on a metal material such as aluminum.

As shown in fig. 45a, the holder 600 includes a mounting portion 601 to which various members are mounted, and a fitting plate 602 which is fitted into the pair of grooves 611 and 612 and on which the mounting portion 601 is provided.

A dimension W2 between portions of the groove portions 611 and 612 fitted to the fitting plate 602 (hereinafter referred to as a height dimension) is set to be slightly smaller than a dimension W1 between the pair of groove portions 611 and 612 (see fig. 44), and as shown in fig. 45c, a chamfer 603 having a diagonal dimension W3 substantially equal to the height dimension W2 is provided at a diagonal portion of the fitting plate 602.

Therefore, when the holder 600 is attached to the side frame 610, as shown in fig. 46, the holder 600 is rotated from the tilted state (the state shown by the broken line) to the state shown by the solid line, and the chamfer 603 is made substantially parallel to the groove portions 611 and 612, whereby the fitting plate 602 can be fitted into the groove portions 611 and 612.

In the present embodiment, since the height W2 of the fitting plate 602 is set slightly smaller than the dimension W1 between the pair of groove portions 611 and 612, the holder 600 can move in the longitudinal direction thereof along the groove portions 611 and 612.

Here, in the present embodiment, as shown in fig. 43, on both sides of the bracket 600 attached to the side frames 610, the restriction plates 630 that restrict the movement of the bracket 600 in the longitudinal direction of the side frames 610 are filled between the pair of groove portions 611, 612.

Further, since the regulating plate 630 also serves as a positioning member of the bracket 600, after the regulating plate 630 is filled in the groove portions 611 and 612, the bracket 600 is preferably filled in the groove portions 611 and 612, but since the regulating plate 630 of the present embodiment is formed of an elastically deformable member such as resin, the regulating plate 630 can be filled between the pair of groove portions 611 and 612 even after the bracket 600 is attached to the side frame 610.

(fifth embodiment)

In the present embodiment, as shown in fig. 48, the discharge port 123C of the guide member 123 is disposed at a substantially center in the width direction (horizontal direction), and the opening direction of the discharge port 123C substantially coincides with the vertical direction (vertical direction) when viewed from the rear side.

That is, in the above embodiment, as shown in fig. 12, the opening direction of the discharge port 123C does not coincide with the vertical direction (vertical direction) when viewed from the rear side, but in the present embodiment, the opening direction of the discharge port 123C substantially coincides with the vertical direction (vertical direction).

Thus, in the present embodiment, the pins P can be smoothly dropped to the distributing mechanism 210 because unnecessary deformation of the pin projector 103 can be prevented.

Further, since the opening direction of the discharge port 123C coincides with the vertical direction (vertical direction), the mold for forming the guide member 123 can be divided up and down when the guide member 123 is molded by the mold, so that the mold structure can be simplified and the productivity of the guide member 123 can be improved.

(sixth embodiment)

In the present embodiment, as shown in fig. 49, a projector vibration damping plate 201B is provided on the projector fixing portion 201 to forcibly damp the vibration of the pin projector 103, and a kick-up vibration damping plate 202A is provided on the upper portion of the outlet side on which the nozzle 202 is placed to suppress the kick-up of the pin P.

As described above, in the present embodiment, the projector vibration control plate 201B prevents the bottle projector 103 from generating excessive vibration, and thus, the occurrence of a problem that the bottle P stops in the bottle projector 103 can be suppressed.

Since the upper bounce damper plate 202A is provided on the upper portion of the outlet side of the mounting nozzle 202, unnecessary vibration such as bouncing of the pins P can be prevented when the pins P fall down to the carrying unit 230.

In the present embodiment, the projector vibration control plate 201B is formed so that a metal plate is in contact with the lower surface side of the ball and socket projector 103, and the rebound vibration control plate 202A is formed so that a plate member made of an elastic member such as rubber is assembled to the upper portion of the outlet side on which the nozzle 202 is mounted, but the structures of the vibration control plates 201B and 202A are not limited thereto.

(seventh embodiment)

In the present embodiment, as shown in fig. 50a and 50b, a pin vibration suppressing member 239 for preventing the pins P from jumping off the conveyor belt 231 is provided in the conveyor unit 230. The vibration suppressing member 239 of the present embodiment is formed of an elastic member such as a string-like rubber extending in a direction orthogonal to the conveying direction of the pins P.

Fig. 50a is a view of the conveying unit 230 viewed from the upper surface side, fig. 50B is a cross-sectional view taken along line 50B-50B of fig. 50a, and fig. 51 is a view of the conveying belt 231 viewed from the arrow F direction of fig. 50 a.

Thus, in the present embodiment, as shown in fig. 51, even if the pins P discharged from the mounting nozzle 202 hit the conveyor belt 231, the pins P are prevented from jumping in the conveyor unit 230, and the pins P can be stably conveyed.

(eighth embodiment)

In the present embodiment, the speed at which the belt of the conveyor 101 is displaced to the backward side in the conveying direction is higher than the speed at which the belt is displaced to the forward side in the conveying direction while reciprocating in the conveying direction without rotating.

That is, fig. 52 is a top view of the conveyor belt 101 of the present embodiment, fig. 53 is a side view of the conveyor belt 101 of the present embodiment, and fig. 54 is an operation principle diagram of the reciprocating mechanism.

As shown in fig. 52 and 53, the conveyor belt 101 includes an endless belt 101A, a tension roller 101B for applying a predetermined tension to the belt 101A, a drive roller 101C for applying a driving force to the belt 101A, a drive mechanism 101D for swinging the drive roller 101C, and the like. In the present embodiment, the belt 101A is fixed to the driving roller 101C by a fixing member such as a bolt 101L (see fig. 53).

The tension roller 101B is displaceable to the frame 101E via the tensioner 101F, and the spring 101G of the tensioner 101F acts a force that separates the tension roller 101B from the drive roller 101C on the tension roller 101B via the tensioner 101F. The driving roller 101C is rotatably assembled in a state of being immovable with respect to the frame 101E.

As shown in fig. 53, the driving mechanism 101D includes an electric motor 101H that generates a rotational force, a crank 101J that rotates (revolves) around the rotational center of the electric motor 101H while being rotated by the electric motor 101H, a slide bar 101K that converts the rotational motion of the crank 101J into a swinging motion and transmits the swinging motion to the driving roller 101C, and the like.

In the rotation range indicated by "downstream" in fig. 54, the drive roller 101C moves to the forward side in the conveyance direction, and in the rotation range indicated by "upstream", the drive roller 101C moves to the backward side in the conveyance direction. In the present embodiment, the electric motor 101H rotates leftward (counterclockwise) as indicated by the arrow in fig. 54.

At this time, since the crank portion 101J rotates at a constant angular velocity, the speed at which the backward moving belt 101A is displaced in the carrying direction is higher than the speed at which the forward moving belt 101A is displaced in the carrying direction, and the pins P can be carried while preventing the belt 101A from being inclined.

That is, in general, when the belt has a dimension in the conveying direction of 2/3 or less which is the dimension in the width direction (the axial direction of the drive roller 101C or the like), the belt is inclined, and thus the conveyor belt cannot be configured in many cases.

In contrast, in the present embodiment, since the belt 101A is reciprocated in the conveying direction without being rotated, the pins P cannot be conveyed even if only the belt 101A reciprocates, although the belt 101A is not inclined in principle.

That is, in the present embodiment, when the belt 101A is displaced toward the forward side in the conveying direction, the pins P are advanced integrally with the belt 101A because the displacement speed of the belt 101A is relatively small.

On the other hand, when the belt 101A is displaced in the backward direction in the conveying direction, the inertial force acting on the pins P exceeds the frictional force generated at the contact portion between the belt and the pins P, and the pins P are stopped at this point by their inertial mass, and only the belt 101A is retracted.

That is, in the present embodiment, when the belt 101A is displaced to the forward side in the conveying direction, the pins P are displaced in accordance with the displacement of the belt 101A, and when the belt 101A is displaced to the backward side in the conveying direction, since only the belt 101A is displaced to the backward side, the pins P can be conveyed while preventing the belt 101A from being inclined.

If the belt 101A is provided with the tilt prevention function, the pins P can be conveyed if the belt 101A is simply rotated without reciprocating, but if the diameter of the tension roller 101B is reduced as in the present embodiment, it is difficult to provide the tilt prevention function on the belt 101A. Therefore, the present embodiment is particularly suitable for a conveyor belt having small diameter dimensions of the tension roller 101B and the drive roller 101C.

In the present embodiment, the belt 101A is a linear body with respect to a center line connecting the center of the tension roller 101B and the center of the drive roller 101C, and therefore, dynamic balance of the belt 101A during reciprocating movement can be achieved. Therefore, an excessive increase in the load of the electric motor 101H that drives the drive roller 101C can be suppressed.

In the present embodiment, the belt 101A is fixed to the driving roller 101C, but is not limited to the present embodiment, and may be fixed to at least one of the tension roller 101B and the driving roller 101C, or may be removed from a fixing member due to a sufficiently large frictional force generated by a contact surface between the belt 101A and the driving roller 101C.
