Patent Document 1: Japanese Unexamined Patent Publication No. 2010-147223

SUMMARY OF THE INVENTION

The technical problem to be solved by the invention

However, since the tape feeder of Patent Document 1 includes two systems of tape insertion paths for introducing the tape, it is necessary to provide two motors, which is disadvantageous in terms of cost.

The present invention has been made in view of the above technical problems, and an object of the present invention is to provide a technique capable of configuring a tape feeder including a plurality of tape insertion paths for introducing an inserted tape while suppressing an increase in cost.

Solutions for technical problems

In order to achieve the above objects, a tape feeder according to the present invention includes: a feeder main body having a plurality of tape insertion paths through which a tape containing components is inserted, and guiding the tape inserted along the tape insertion path to a component supply position. ; and a tape introduction mechanism having a single motor, which introduces the tape to the component supply position by transmitting the driving force generated by the motor to the tape inserted into the tape insertion path. The driving force generated by the motor is transmitted to the belt of one belt insertion path, and the belt insertion path for carrying out the introduction of the tape can be switched between a plurality of belt insertion paths.

The component mounting machine which concerns on this invention is equipped with the said tape feeder, and the mounting head which mounts the component supplied from the tape feeder on a board|substrate.

The present invention (tape feeder, component mounting machine) thus constituted includes a tape introduction mechanism for introducing a tape by transmitting a driving force generated by a single motor to the tape inserted into the tape insertion path. Furthermore, the tape introduction mechanism can switch the tape for carrying out tape introduction between the plurality of tape insertion paths by transmitting the driving force of the motor to the tape inserted into one of the tape insertion paths selected from the plurality of tape insertion paths. Insert road. That is, by alternately switching the transmission destination of the driving force generated by the single motor among the plurality of tape insertion paths, even a single motor is configured to be able to introduce the tape through the plurality of tape insertion paths. Accordingly, the number of motors can be suppressed, and a tape feeder including a plurality of tape insertion paths for introducing an inserted tape can be configured while suppressing an increase in cost.

In addition, the tape feeder may be configured such that the main body of the feeder has two tape insertion paths as a plurality of tape insertion paths, and the tape introduction mechanism further includes a driving roller disposed between the two tape insertion paths. And rotate by the driving force of the motor, by making the belt inserted in the first belt insertion path of the two belt insertion paths and the peripheral surface of the driving roller press contact while the driving roller is rotated in the first direction, utilizing the force acting on the belt. The belt is introduced into the first belt insertion path by the friction force between the peripheral surface of the drive roller and the second belt insertion path different from the first belt insertion path while being inserted into the two belt insertion paths. While the belt is pressed against the peripheral surface of the driving roller, the driving roller is rotated in a second direction opposite to the first direction, and the second belt is inserted into the belt in the path by utilizing the frictional force acting between the belt and the peripheral surface of the driving roller. import.

In this structure, a drive roller is provided between the two tape insertion paths (that is, the first tape insertion path and the second tape insertion path). Furthermore, introduction of the tape inserted into the first tape insertion path can be performed by rotating the drive roller in the first direction while bringing the peripheral surface of the drive roller into pressure contact with the tape. In addition, introduction of the tape inserted into the second tape insertion path can be performed by rotating the drive roller in the second direction while pressing the peripheral surface of the drive roller against the tape. That is, the driving roller used for introducing the tape can be shared by the first tape insertion path and the second tape insertion path. Thereby, the number of objects of a drive roller can be suppressed, and cost increase can be suppressed more effectively.

In addition, the tape feeder may be configured such that the tape introduction mechanism restricts the movement of the tape inserted into the second tape insertion path due to the frictional force with the peripheral surface of the driving roller while the driving roller is rotating in the first direction. , while the driving roller rotates in the second direction, the belt introduction mechanism restricts the movement of the belt inserted into the first belt insertion path according to the frictional force with the peripheral surface of the driving roller. This configuration can suppress the introduction of the tape in the first tape insertion way from affecting the tape in the second tape insertion way, and can prevent the introduction of the tape in the execution of the second tape insertion way from affecting the tape in the first tape insertion way. , is preferred.

Specifically, the tape feeder can be configured such that the tape introduction mechanism has a first one-way roller facing the drive roller across the first tape insertion path, and press-contacting the tape inserted into the first tape insertion path. on the driving roller; and the second one-way roller, facing the driving roller across the second belt insertion path, so that the belt inserted into the second belt insertion path is pressed against the driving roller, and the first one-way roller is driven by the The driving roller rotating in the first direction rotates, allowing the belt inserted into the first belt insertion path to move according to the frictional force with the peripheral surface of the driving roller. On the other hand, while the driving roller rotates in the second direction, the second A one-way roller supports the belt inserted into the first belt insertion path by overcoming the frictional force acting between the belt and the driving roller, restricts the movement of the belt according to the frictional force with the peripheral surface of the driving roller, and the second one-way roller The direction roller rotates by being driven by the driving roller rotating in the second direction, allowing the belt inserted into the second belt insertion path to move according to the frictional force with the peripheral surface of the driving roller. During rotation in the first direction, the second one-way roller supports the belt inserted into the second belt insertion path by overcoming the frictional force acting between the belt and the driving roller, restricting the belt according to the friction with the peripheral surface of the driving roller. force to move. Thus, it is possible to suppress the influence of the lead-in of the tape in the execution of the first tape insertion way on the tape of the second tape insertion way, and it is possible to suppress the influence of the lead-in of the tape in execution of the second tape insertion way on the tape of the first tape insertion way. influences.

In addition, various specific configurations for realizing switching of the rotation direction of the drive motor between the first direction and the second direction are conceivable. For example, the tape feeder may be configured such that the tape introduction mechanism switches the rotation direction of the drive roller between the first direction and the second direction by switching the rotation direction of the motor. Alternatively, the tape feeder may be configured such that the tape introduction mechanism has: a first rotating member that is rotated by a motor that rotates in a predetermined direction to rotate the drive roller in the first direction; The rotating member is rotated by receiving the driving force of the motor rotating in a predetermined direction to rotate the driving roller in the second direction, and the transmission destination of the driving force of the motor is switched between the first rotating member and the second rotating member. Switching of the rotational direction of the drive roller between the first direction and the second direction is performed.

In addition, the tape feeder may be configured such that the tape introduction mechanism has: a first urging member for urging the first one-way roller toward the drive roller; and a second urging member for pushing the second one-way roller to The rollers apply force pushing against the drive rollers. In this way, the belt can be brought into pressure contact with the drive roller by passing the first one-way roller and the second one-way roller with a simple structure of the first urging member and the second urging member.

In addition, the tape feeder may be configured such that the tape introduction mechanism includes: a first driven roller that faces the drive roller across the first tape insertion path; and a second driven roller that is inserted through the second tape. The first driven roller is driven to rotate by driving the roller while pressing the belt inserted into the first belt insertion path against the driving roller rotating in the first direction, allowing the belt to be inserted into the first belt. On the other hand, during the rotation of the driving roller in the second direction, the first driven roller releases the pressure contact of the belt inserted into the second belt insertion path to the driving roller, and restricts the belt from being connected to the driving roller. The frictional force between the peripheral surfaces of the belt moves, and the second driven roller rotates by being driven by the driving roller while pressing the belt inserted into the second belt insertion path against the driving roller rotating in the second direction, allowing the insertion The movement of the belt to the second belt insertion path, on the other hand, during the rotation of the driving roller in the first direction, the second driven roller restricts the belt inserted in the first belt insertion path by releasing the pressure contact of the driving roller. Moves by friction with the peripheral surface of the drive roller. Thus, it is possible to suppress the influence of the lead-in of the tape in the execution of the first tape insertion way on the tape of the second tape insertion way, and it is possible to suppress the influence of the lead-in of the tape in execution of the second tape insertion way on the tape of the first tape insertion way. influences.

In addition, the tape feeder may be configured such that the motor is disposed between the first tape insertion path and the second tape insertion path. This structure can effectively utilize the space between the first tape insertion path and the second tape insertion path to arrange the motor, which is advantageous for realizing miniaturization of the tape feeder.

In addition, the tape feeder may be configured such that the tape introduction mechanism has a structure in which a speed reducer is disposed between the first tape insertion path and the second tape insertion path, and the speed reducer reduces the driving force of the motor to drive the tape feeder. Roll pass. This structure can effectively utilize the space between the first tape insertion path and the second tape insertion path to arrange the speed reducer, which is advantageous for realizing miniaturization of the tape feeder.

Detailed ways

FIG. 1 is a plan view showing a schematic configuration of a surface mounter equipped with a tape feeder according to the present invention. In addition, in this figure, the XYZ rectangular coordinate axis|shaft which makes a vertical direction into Z direction is shown. In the surface mounter 1 , a board transport mechanism 2 is disposed on a base 11 , and can transport a board 3 in a predetermined transport direction X. More specifically, the substrate transfer mechanism 2 includes a pair of conveyors 21 , 21 for transferring the substrate 3 from the right side to the left side in FIG. 1 on the base 11 . The conveyors 21 and 21 stop the loaded substrate 3 at a predetermined mounting work position (the position of the substrate 3 shown in the figure). Then, the substrate 3 conveyed in this way is fixedly held by a holding device (not shown). Next, the electronic components (not shown) supplied from the tape feeder 5 of the component storage section 4 are transferred by the head unit 6 to the substrate 3 fixedly held at the mounting operation position. When the head unit 6 reciprocates between above the component accommodating portion 4 and above the substrate 3 multiple times in this way to complete the mounting process of all the components to be mounted on the substrate 3 , the substrate transport mechanism 2 unloads the substrate 3 .

On both sides of the substrate conveyance mechanism 2, the above-mentioned component storage portions 4 are arranged. These components storage parts 4 have the structure which arranged the some tape feeder 5 along the X direction. In addition, a tape reel (not shown) on which a tape storing and holding electronic components is wound is disposed on each tape feeder 5 , and the tape pulled out from the tape reel is attached to the tape feeder 5 . Then, the tape feeder 5 intermittently supplies the electronic components in the tape to the component supply position L by sending out the mounted tape to the component supply position L provided at the front end portion on the head unit 6 side. Thereby, the head unit 6 can pick up a component at the component supply position L using the suction nozzle 61 . In addition, the tape feeder 5 will be described in detail later.

In addition, in this embodiment, a head drive mechanism 7 is provided in addition to the substrate conveyance mechanism 2 . The head drive mechanism 7 is a mechanism for moving the head unit 6 in the X-axis direction and the Y-axis direction (directions perpendicular to the X-axis and Z-axis directions) within a predetermined range of the base 11 . Then, the electronic component sucked by the suction nozzle 61 is conveyed from the position above the component housing portion 4 to the position above the substrate 3 by the movement of the head unit 6 . That is, the head driving mechanism 7 has a head support member 71 extending in the X-axis direction, and the head support member 71 supports the head unit 6 so as to be movable along the X-axis. In addition, the head supporting member 71 is supported by fixed rails 72 in the Y-axis direction with both ends above the substrate transfer mechanism 2 , and the head supporting member 71 is movable in the Y-axis direction along the fixed rails 72 . Furthermore, the head drive mechanism 7 has an X-axis servo motor 73 as a drive source for driving the head unit 6 in the X-axis direction, and a Y-axis servo motor 74 as a drive source for driving the head unit 6 in the Y-axis direction. The motor 73 is connected to the ball screw 75 , and by operating the motor 73 , the head unit 6 is driven in the X-axis direction via the ball screw 75 . On the other hand, the motor 74 is connected to the ball screw 76 , and by operating the motor 74 , the head support member 71 is driven in the Y-axis direction via the ball screw 76 .

The head unit 6 conveys the electronic component to the board|substrate 3 in the state suction-held by the suction nozzle by the head drive mechanism 7, and transfers it to a predetermined position. That is, in the head unit 6, eight head units (not shown) are arranged in a row at equal intervals along the X-axis direction (the direction in which the substrate 3 is conveyed by the substrate conveyance mechanism 2) and are arranged to extend in the vertical direction Z and freely move up and down. the mounting head shown. Suction nozzles 61 are attached to the front ends of the respective mounting heads. Then, the head unit 6 is moved upwards of the component storage part 4 by the head drive mechanism 7, and the tip part of the suction nozzle 61 abuts on the electronic component supplied from the component storage part 4 in an appropriate posture, and sucks and holds it. At this time, after the suction nozzle 61 descends to the electronic component, it suctions the electronic component and then ascends. In this manner, the head unit 6 is conveyed above the substrate 3 with the electronic components sucked and held by the suction nozzles 61 , and the electronic components are transferred to the substrate 3 at a predetermined position.

The above is the outline of the overall structure of the surface mounting machine 1 . Next, the tape feeder 5 will be described in detail. FIG. 2 is a partial side view schematically showing a first embodiment of the tape feeder 5 . In this figure and the figures shown later, the delivery direction D and the vertical direction Z in which the tape feeder 5 sends out the tape TP are appropriately shown, and the parts hidden by other members are appropriately shown by dotted lines. In addition, let the side of the arrow in the delivery direction D be the front side, and let the side opposite to the arrow in the delivery direction D be the rear side. Furthermore, below, expressions such as "clockwise" and "counterclockwise" in the side views referred to are used appropriately to indicate the rotational direction of the components.

The tape feeder 5 is provided with the feeder main body 50 long along the Y direction. In the feeder main body 50, two tape insertion paths P1 and P2 into which the tape TP can be inserted are provided along the delivery direction D. As shown in FIG. That is, at the rear end of the feeding direction D of the feeder main body 50, two insertion ports A1 and A2 are arranged vertically in the vertical direction Z and are vacant. The tape insertion path P1 extends linearly from the insertion port A1 to a junction J ahead of the insertion port A1 in the feeding direction D, and the tape insertion path P1 extends from the insertion port A2 to the junction J while bending upward halfway. The tape insertion paths P1 and P2 merge at the confluence point J to become the tape supply path P0 and extend linearly in the delivery direction D to reach the discharge port A0 provided at the front end of the feeder main body 50 in the delivery direction D.

And, the operator can insert the tape TP into the feeder main body 50 from the insertion ports A1, A2 of the tape feeder 5 mounted on the surface mounter 1 along the tape insertion paths P1, P2. On the other hand, a tape introduction mechanism 51 is arranged near the insertion ports A1 and A2 in the feeder main body 50, and the tape TP inserted into the tape insertion paths P1 and P2 is guided toward the component supply position L by the tape introduction mechanism 51. into the feeder body 50.

The tape introduction mechanism 51 has: a driving roller 52 having a smooth circumferential surface; a single introduction motor 53 disposed at a position ahead of the driving roller 52 in the delivery direction D; The generated driving force is decelerated and transmitted to the driving roller 52 . The speed reducer 54 has a driven gear 540 that is coaxial with the drive roller 52 and integrated with the drive roller 52 (that is, rotates integrally). 540 to transmit the driving force introduced into the motor 53 to the driven gear 540 .

Further, the tape introduction mechanism 51 has: a one-way sprocket 55a facing the drive roller 52 from above across the tape insertion path P1; and a one-way sprocket 55b facing the drive roller 52 from below across the tape insertion path P2. . A one-way clutch (not shown) that can only rotate counterclockwise in FIG. 2 and cannot rotate clockwise is attached to the rotation shaft of the one-way sprocket 55a. Therefore, the one-way sprocket 55a can only rotate counterclockwise and cannot rotate clockwise. On the other hand, a one-way clutch (not shown) that can only rotate clockwise and cannot rotate counterclockwise is attached to the rotation shaft of the one-way sprocket 55b. Therefore, the one-way sprocket 55b can only rotate clockwise and cannot rotate counterclockwise.

On the peripheral surface of each one-way sprocket 55a, 55b, a plurality of protrusions 551 are arranged along the circumferential direction. These protrusions 551 are provided at the same pitch as the arrangement pitch of the plurality of holes provided in the tape TP, and can be engaged with the holes of the tape TP inserted into the tape insertion paths P1 and P2. In addition, the height of the protrusion 551 is formed slightly shallower than the depth of the TP hole, and the tip of the protrusion 551 does not protrude from the TP hole when the protrusion 551 is engaged with the TP hole.

Moreover, the belt introduction mechanism 51 has the lever 561 and the urging member 562 (elastic member, such as a spring) corresponding to each one-way sprocket 55a, 55b. One end of the rod 561 is pivotally supported by the feeder main body 50 so as to be free to swing, and the other end of the rod 561 is attached to the feeder main body 50 via a biasing member 562 . As a result, the central portion (that is, the portion between one end and the other end) of the lever 561 is biased toward the driving roller 52 side. And each one-way sprocket 55a, 55b is attached to the center part of the corresponding lever 561, and is biased toward the drive roller 52 side.

The tape introduction mechanism 51 having such a structure sandwiches the tape TP inserted from the insertion port A1 along the tape insertion path P1 between the peripheral surface of the one-way sprocket 55 a and the peripheral surface of the driving roller 52 . The one-way sprocket 55 a presses (that is, abuts) the belt TP of the belt insertion path P1 against the peripheral surface of the driving roller 52 by the urging force of the urging member 562 . As a result, frictional force is generated between the belt TP and the peripheral surface of the driving roller 52 . Thus, when the driving roller 52 is rotated in the forward direction R1 (clockwise) by the driving force of the lead-in motor 53 rotating in the forward direction, the belt TP in the belt insertion path P1 passes through friction with the peripheral surface of the driving roller 52 . Force is introduced into the feeder main body 50 in the delivery direction D. FIG. At this time, the one-way sprocket 55a is driven by the drive roller 52 and rotates counterclockwise. That is, the one-way sprocket 55a acts on the protrusions 551 sequentially engaged with a plurality of holes provided on the tape TP by the friction force between the one-way sprocket 55a and the tape TP introduced into the feeder main body 50 in the feeding direction D. On the other hand, driven by the driving roller 52 rotating in the forward direction R1 , the tape TP inserted into the tape insertion path P1 is allowed to be introduced in the delivery direction D by the frictional force with the peripheral surface of the driving roller 52 .

On the other hand, the tape introduction mechanism 51 sandwiches the tape TP inserted from the insertion port A2 along the tape insertion path P2 between the peripheral surface of the one-way sprocket 55 b and the peripheral surface of the drive roller 52 . The one-way sprocket 55b press-contacts the belt TP of the belt insertion path P2 to the peripheral surface of the driving roller 52 by the urging force of the urging member 562 . As a result, frictional force is generated between the belt TP and the peripheral surface of the driving roller 52 . Thus, when the driving roller 52 is rotated in the reverse direction (counterclockwise) by the driving force of the lead-in motor 53 rotating in the negative direction (reverse to the above-mentioned positive direction), the belt TP on the belt insertion path P2 passes through the driving roller 52 The frictional force between the peripheral surfaces is introduced into the feeder main body 50 toward the delivery direction D. At this time, the one-way sprocket 55b acts on the protrusions 551 sequentially engaged with the plurality of holes provided on the tape TP by the frictional force between the one-way sprocket 55b and the tape TP introduced into the feeder main body 50 in the delivery direction D. The force is driven by the driving roller 52 to rotate clockwise. That is, the one-way sprocket 55b rotates driven by the drive roller 52 rotating in the reverse direction, whereby the tape TP inserted into the tape insertion path P2 is allowed to be sent out toward the Direction D import.

However, it is also assumed that the tape TP exists in the tape insertion path P2 when the drive roller 52 is rotated in the forward direction R1 to introduce the tape TP in the tape insertion path P1. In this case, it is preferable to suppress movement of the tape TP in the tape insertion path P2 in the direction opposite to the delivery direction D due to the frictional force with the driving roller 52 . Therefore, as described above, the one-way sprocket 55b is configured so as not to rotate counterclockwise. That is, while the drive roller 52 is rotating in the forward direction R1, the one-way sprocket 55b engages with the hole of the tape TP inserted into the tape insertion path P2 through the protrusion 551, and overcomes the friction acting between the tape TP and the drive roller 52. The belt TP is supported by force. Accordingly, the one-way sprocket 55b can restrict the movement of the tape TP in the tape insertion path P2 in the direction opposite to the delivery direction D due to the frictional force with the driving roller 52 rotating in the forward direction R1.

For the same reason, the one-way sprocket 55a is configured so as not to rotate clockwise. That is, while the drive roller 52 is rotating in the reverse direction, the one-way sprocket 55a engages with the hole of the tape TP inserted into the tape insertion path P1 through the protrusion 551, and overcomes the frictional force acting between the tape TP and the drive roller 52. And support the belt TP. Thus, the one-way sprocket 55a can restrict the movement of the tape TP in the tape insertion path P1 in the direction opposite to the delivery direction D by the frictional force with the drive roller 52 rotating in the reverse direction.

The tape TP introduced along the tape insertion path P1, P2 is driven by the tape introduction mechanism 51 and further enters from the tape insertion path P1, P2 to the tape supply path P0 or in the state where there is no tape TP already introduced in the tape supply path P0. Arrive at belt supply road P0. On the other hand, in the feeder main body 50, the supply sprocket 57 is arrange|positioned facing the tape supply path P0. On the peripheral surface of the supply sprocket 57, a plurality of protrusions 571 are arranged along the circumferential direction. The protrusions 571 are set at the same pitch as the arrangement pitch of the plurality of holes provided in the tape TP. Thereby, the protrusion 571 of the supply sprocket 57 engages with the hole of the tape TP which entered the tape supply path P0 and reached the supply sprocket 57 . And the supply sprocket 57 is rotated clockwise by the supply motor (not shown) built into the feeder main body 50, and the tape TP is sent out to the delivery direction D by this. Thus, the tape TP is discharged from the discharge port A0 toward the outside of the feeder main body 50 after passing the component supply position L, and is discarded to a waste box (not shown) arranged below the discharge port A0.

However, the tape TP is composed of a carrier tape and a cover tape attached to the carrier tape. The carrier tape has recesses opening upward at constant intervals, and components are accommodated in the recesses. In addition, a plurality of holes engaged with the respective sprockets 55a, 55b, and 57 are provided on one side in the width direction of the carrier tape so as to be aligned in the longitudinal direction (feeding direction D). On the other hand, the cover tape is bonded to the upper surface of the carrier tape at both sides in the width direction to continuously cover the opening of the carrier tape. In this way, the components housed in the tape TP are held in the concave portion of the carrier tape in a state covered by the cover tape.

Therefore, in order to pick up a component at the component supply position L, the suction nozzle 61 needs to expose the component accommodated in the tape TP before reaching the component supply position L. As a method of exposing the element, various known methods can be used. Specifically, in a state where one side of the cover tape in the width direction is adhered to the carrier tape, the other side of the cover tape in the width direction is peeled from the carrier tape in the feeding direction D and rolled up, so that components exposed. Alternatively, the center of the width direction of the cover tape may be torn in the delivery direction D and the tear line may be rolled up to both sides to expose the element. In the case of these methods, after the component is picked up at the component supply position L, the cover tape is discharged from the discharge port A0 together with the carrier tape, and is discarded in a discard box.

Furthermore, in order to control each part of the tape feeder 5, various sensors I1, I2, O1, O2 and the control apparatus 500 are provided in the feeder main body 50. As shown in FIG. The control device 500 is a computer composed of a CPU (Central Processing Unit: central processing unit) and a memory, and collectively controls the operation of each part constituting the tape feeder 5 . The tape insertion sensor I1 is disposed between the insertion port A1 and the driving roller 52 so as to face the tape insertion path P1, and detects the presence or absence of the tape TP in the vicinity of the insertion port A1 of the tape insertion path P1. The tape insertion sensor I2 is arranged between the insertion port A2 and the driving roller 52 so as to face the tape insertion path P2, and detects the presence or absence of the tape TP in the vicinity of the insertion port A2 of the tape insertion path P2. The tape end sensor O1 is disposed between the drive roller 52 and the junction J so as to face the tape insertion path P1, and detects the presence or absence of the tape TP in the vicinity of the junction J of the tape insertion path P1. The tape end sensor O2 is disposed so as to face the tape insertion path P2 between the drive roller 52 and the junction J, and detects the presence or absence of the tape TP in the vicinity of the junction J of the tape insertion path P2. The various sensors I1, I2, O1, and O2 are composed of optical sensors, for example, and output a high-level signal to the control device 500 when a tape TP is detected, and output a low-level signal when a tape TP is not detected. The flat signal is output to the control device 500 . Furthermore, the control device 500 controls the motor connected to the drive roller 52 and the supply sprocket 57 based on the detection results of various sensors I1, I2, O1, and O2 to control feeding out of the tape TP as shown in FIG. 3 , for example.

FIG. 3 is a diagram showing an example of operations performed by the tape feeder. In this figure, the operation of functional parts such as sensors I1 , I2 , O1 , O2 , driving roller 52 , and supply sprocket 57 is shown corresponding to each state. Incidentally, in this figure, an underline indicates that the operation of each functional unit changes with state transition. In addition, a symbol "◯" indicates a case where the output signal of the sensor is at a high level, and a symbol "×" indicates a case where the output signal of the sensor is at a low level.

In FIG. 3 , the tape TP is inserted into the tape insertion path P1 from a state in which the tape TP is not inserted in any of the tape insertion paths P1 and P2 of the tape feeder 5 mounted on the surface mounter 1 and then inserted into the tape insertion path P1. The operation when the tape feeder 5 is equipped with the tape TP is shown in association with states 1 to 6 . Initially, no tape TP is inserted into the two tape insertion paths P1, P2, the output signals of the sensors I1, I2, O1, and O2 are all at low level, and the driving roller 52 and the supply sprocket 57 are both stopped (closed) (state 1) . When the operator inserts the tape TP into the tape insertion path P1 from the state 1, the tape insertion sensor I1 detects the tape TP of the tape insertion path P1, and outputs a high-level signal (state 2).

Next, when the operator turns on the operation switch 501 provided on the upper surface of the tape feeder 5, the driving roller 52 starts to rotate in the forward direction R1 (state 3). Thereby, the tape TP inserted into the tape insertion path P1 is introduced toward the delivery direction D along the tape insertion path P1. When the leading end of the tape TP reaches the opposite position of the tape end sensor O1, the output signal of the tape end sensor O1 changes to high level (state 4). At this time, the drive roller 52 rotates at a fast-forward speed higher than the normal speed during the state 3 , and after transitioning to the state 4 , the rotation speed is reduced to rotate at the normal speed.

When time T1 has elapsed since the output signal of the tape end sensor O1 changed to high level and the leading end of the tape TP reaches the vicinity of the supply sprocket 57, the supply sprocket 57 starts to rotate clockwise (state 5). Then, when the time T2 elapses and the leading end of the tape TP engages with the supply sprocket 57, the rotation of the drive roller 52 stops (state 6).

Incidentally, a configuration may be adopted in which after the leading end of the tape TP is engaged with the supply sprocket 57, the supply sprocket 57 also rotates clockwise, and the operator performs the step of peeling off the cover tape. In this structure, when the front end of the tape TP stops in front of the part where the components are exposed, or the tape feeder 5 has a mechanism for automatically exposing the components, the front end of the tape TP passes through the part where the parts are exposed. , the exposed tip of the component reaches the vicinity of the component supply position L, and the supply sprocket 57 stops.

In this way, attachment of the tape TP inserted toward the tape insertion path P1 to the tape feeder 5 is completed. In addition, the sending out of the tape TP in the sending direction D after the front end of the tape TP is engaged with the supply sprocket 57 is mainly carried out by the supply sprocket 57 . Incidentally, the one-way sprocket 55 a rotates counterclockwise while being pulled by the supply sprocket 57 via the tape TP, allowing the tape TP to be sent out in the delivery direction D by the supply sprocket 57 .

Next, in FIG. 3 , actions and states 7 to 11 when the tape TP is inserted into the tape insertion path P2 from the state where the tape TP is inserted only into the tape insertion path P1 and the tape TP is attached to the tape feeder 5 are described. Connect and express. That is, when the operator inserts the tape TP into the tape insertion path P2, the tape insertion sensor I2 detects the tape TP of the tape insertion path P2, and outputs a high-level signal (state 7). Then, when the rear end of the tape TP previously mounted on the tape insertion path P1 passes the tape insertion sensor I1, and the output signal of the tape insertion sensor I1 changes to a low level, it is judged that the tape is near the end of the tape in the tape insertion path P1, and the roller is driven. 52 Start the rotation towards reverse at fast forward speed (state 8). Thereby, the tape TP inserted into the tape insertion path P2 is introduced toward the delivery direction D along the tape insertion path P2.

Incidentally, at the moment when the driving roller 52 starts rotating in the reverse direction, the belt TP is sandwiched between the one-way sprocket 55 a of the belt insertion path P1 and the driving roller 52 . However, since the one-way sprocket 55a supports the tape TP of the tape insertion path P1 against the frictional force with the driving roller 52 rotating in the reverse direction through the protrusion engaged with the hole of the tape TP of the tape insertion path P1, The tape TP is sent out in the sending direction D by the supply sprocket 57 without moving in the direction opposite to the sending direction D.

Then, when the leading end of the tape TP inserted into the tape insertion path P2 reaches the tape end sensor O2 and the output signal of the tape end sensor O2 becomes high, the reverse rotation of the drive roller 52 stops (state 9). In this way, the tape TP inserted into the tape insertion path P2 is on standby at the position where it has entered the tape end sensor O2.

When the rear end of the tape TP in the tape insertion path P1 passes the tape end sensor O1 and the output signal of the tape end sensor O1 changes to low level (in other words, when it is detected that the tape TP previously mounted on the tape insertion path P1 is about to be used up). end), the driving roller 52 starts to rotate toward the reverse direction R2 at a normal speed in synchronization with the tape feeding of the tape insertion path P1 by the supply sprocket 57 (state 9). As a result, the tape TP waiting in the tape insertion path P2 is further introduced in the delivery direction D toward the supply sprocket 57 , following the tape TP in the tape insertion path P1 moving in the delivery direction D. Then, when the time T3 elapses and the leading end of the tape TP engages with the protrusion 571 of the supply sprocket 57, the rotation of the driving roller 52 stops (state 11). In this way, attachment of the tape TP inserted toward the tape insertion path P2 to the tape feeder 5 is completed.

Next, in FIG. 3 , actions and states 12 to 16 when the tape TP is inserted into the tape insertion path P1 from the state where the tape TP is inserted only into the tape insertion path P2 and the tape TP is attached to the tape feeder 5 are shown. Connect and express. Attachment of this tape TP can be performed by performing the same operation|movement as the operation|movement performed to the tape insertion path P2 in states 7-11 to the tape insertion path P1. And after that, by alternately executing the processing of states 7 to 11 and the processing of states 12 to 16, the tape TP can be attached to the tape feeder 5 sequentially.

In this way, in the example of FIG. 3, the control device 500 selects one of the tape insertion paths P1, P2, the corresponding tape insertion sensors I1, I2 whose signal levels change from low to high, as the execution tape insertion path. TP's imported object. At this time, the operator assumes that the signal levels of the tape insertion sensors I1 and I2 are simultaneously switched to high for reasons such as simultaneously inserting the tape TP into the tape insertion paths P1 and P2 . On the other hand, in this case, the control device 500 may be configured such that any one of the tape insertion paths P1 and P2 (for example, the tape insertion path P1 ) is preferentially selected.

As described above, the tape feeder 5 of the first embodiment includes the tape introduction mechanism 51 that transmits the drive of the single introduction motor 53 to the tape TP inserted into the tape insertion path P1, P2. Force while importing with TP. Furthermore, the tape introduction mechanism 51 can transmit the driving force of the driving roller 52 to the tape TP inserted into one of the tape insertion paths P1, P2 selected from the plurality of tape insertion paths P1, P2, so that Alternately switch the tape insertion way to execute import with TP. Specifically, in the above-mentioned example of FIG. 3 , in states 1 to 6, tape insertion way P1 is selected as the tape insertion way to execute tape TP lead-in, and in states 7 to 11, tape insertion way P2 is selected as Execute import with TP with insert. That is, it is configured to switch the transmission destination of the driving force generated by the single lead-in motor 53 between the multiple tape insertion paths P1 and P2, so that even a single lead-in motor 53 can be used in multiple tape insertion paths. Import with TP is executed in P1 and P2. Thereby, the number of objects of the introduction motor 53 can be suppressed, and the tape feeder 5 provided with the several tape insertion paths P1 and P2 for introducing the inserted tape TP can be comprised, suppressing cost increase.

Moreover, the drive roller 52 arrange|positioned between two tape insertion paths P1 and P2 is provided in the tape feeder 5 of 1st Example. Furthermore, introduction of the tape TP inserted into the tape insertion path P1 can be performed by rotating the drive roller 52 in the forward direction R1 while pressing the peripheral surface of the drive roller 52 against the tape TP. In addition, introduction of the tape TP inserted into the tape insertion path P2 can be performed by rotating the driving roller 52 in the reverse direction while pressing the peripheral surface of the driving roller 52 against the tape TP. That is, the driving roller 52 used for introducing the tape TP can be shared by the tape insertion path P1 and the tape insertion path P2. Thereby, the number of objects of the drive roller 52 can be suppressed, and cost increase can be suppressed more effectively.

In addition, while the drive roller 52 rotates in the forward direction R1, the tape introduction mechanism 51 restricts the movement of the tape TP inserted into the tape insertion path P2 due to the frictional force with the peripheral surface of the drive roller 52, and when the drive roller 52 rotates in the reverse direction. During the rotation, the tape introduction mechanism 51 restricts the movement of the tape TP inserted into the tape insertion path P1 according to the frictional force with the peripheral surface of the driving roller 52 . This structure can suppress the influence of the lead-in of the tape TP in the execution of the tape insertion way P1 on the tape TP of the tape insertion way P2, and can suppress the influence of the introduction of the tape TP in the execution of the tape insertion way P2 on the tape TP of the tape insertion way P1. , is preferred.

Incidentally, in order to accurately feed out the tape TP by utilizing the frictional force between the driving roller 52 and the tape TP, it is important to bring the tape TP into pressure contact with the driving roller 52 . On the other hand, the belt introduction mechanism 51 has the urging member 562 which urges the one-way sprocket 55a, 55b to the drive roller 52. As shown in FIG. In this way, the pressure contact of the belt TP formed by the one-way sprockets 55a and 55b to the driving roller 52 is realized by the simple structure of the urging member 562 .

In addition, the lead-in motor 53 is arranged between the tape insertion path P1 and the tape insertion path P2. This configuration can effectively utilize the space between the tape insertion path P1 and the tape insertion path P2 to arrange the lead-in motor 53 , which is advantageous for downsizing the tape feeder 5 .

Also, a speed reducer 54 that decelerates the driving force of the introduction motor 53 and transmits it to the driving roller 52 is disposed between the tape insertion path P1 and the tape insertion path P2. This configuration can effectively utilize the space between the tape insertion path P1 and the tape insertion path P2 to arrange the speed reducer 54 , which is advantageous for downsizing the tape feeder 5 .

Fig. 4 is a partial side view schematically showing a second embodiment of the tape feeder. Fig. 5 is a diagram schematically showing the structure of a clutch included in the tape feeder of Fig. 4 . The second embodiment differs from the first embodiment mainly in the structure for transmitting the driving force introduced into the motor 53 to the driving roller 52, and the first embodiment is the same as the second embodiment in other structures. In this regard, the following description will focus on the points of difference from the first embodiment, and the description of the points in common with the first embodiment will be appropriately omitted. In addition, it goes without saying that the same effect can be exerted by having the same structure as that of the first embodiment.

The tape feeder 5 of the first embodiment performs switching of the rotation direction of the driving roller 52 between the forward direction R1 and the reverse direction R2 by switching the rotation direction of the introduction motor 53 between the positive direction and the negative direction. On the other hand, the tape feeder 5 of 2nd Example has the structure which switches the rotation direction of the drive roller 52 between forward direction R1 and reverse direction R2, without switching the rotation direction of the introduction motor 53.

The speed reducer 54 with the introduction mechanism 51 has two clutches C1 and C2 adjacent to the driven gear 540 integrally attached to the drive roller 52 . Furthermore, the speed reducer 54 has a gear 541 which is rotated by receiving the driving force of the introduction motor 53 , and a gear 542 which meshes with the gear 541 and rotates in a direction opposite to the gear 541 . Furthermore, the clutch C1 meshes with the gear 541 and the driven gear 540 between them, and transmits/blocks the force from the gear 541 to the driven gear 540 . On the other hand, the clutch C2 meshes with the gear 542 and the driven gear 540 between them, and transmits/blocks the force from the gear 542 to the driven gear 540 . Transmission and disengagement of the clutches C1 and C2 are performed by solenoids S54 respectively provided in the clutches C1 and C2. Details of the structure and operation of the clutches C1 and C2 are shown in FIG. 5 .

The clutch C1 has a gear 582 rotatably supported by a bearing 581 attached to the feeder main body 50 , and a gear 584 rotatably supported by a bearing 583 attached to the feeder main body 50 . The gear 582 meshes with the gear 541 constituting the speed reducer 54 and rotates along with the gear 541 . The gear 584 meshes with the driven gear 540 to rotate the driven gear 540 . The gear 582 and the gear 584 face each other in the axial direction, and are biased toward each other in the direction of separating in the axial direction by an elastic member (spring or the like) not shown in the figure.

The gear 582 is approached or separated from the gear 584 by the solenoid S54. That is, the shaft Ss of the solenoid S54 can move forward and backward with respect to the projection of the gear 582 . In addition, as shown in the "cut state" of FIG. 5 , in the state where the shaft Ss is retracted, the shaft Ss comes into contact with the protrusion of the gear 582 through the thin portion provided at the front end, and the gear 582 is separated from the gear 584 in the axial direction. , the engaging claw 582a of the gear 582 is axially separated from the engaging hole 584a of the gear 584 . In this state, force cannot be transmitted from the gear 582 to the gear 584 (that is, the clutch C1 is disengaged), and the driving force transmitted from the lead-in motor 53 to the gear 541 is not transmitted to the driven gear 540 . On the other hand, as shown in the "transmission state" of Fig. 5, in the state where the shaft Ss advances, the shaft Ss contacts the protrusion of the gear 582 through the thick part, and the gear 582 is directed toward the gear 582 in the axial direction against the acting force. The gear 584 side is pressed in. Accordingly, the engaging claw 582 a of the gear 582 engages with the engaging hole 584 a of the gear 584 . As a result, force can be transmitted from the gear 582 to the gear 584 (that is, the clutch C1 is engaged), and the driving force transmitted from the lead-in motor 53 to the gear 541 is transmitted to the driven gear 540 to rotate the driving roller 52 .

Clutch C2 also has the same structure as clutch C1. However, gear 582 of clutch C2 meshes with gear 542 instead of gear 541 . Thus, when the clutch C2 is disengaged, the transmission of force from the gear 542 to the driven gear 540 is cut off. On the other hand, when the clutch C2 is engaged, power can be transmitted from the gear 542 to the driven gear 540 , and the drive force transmitted from the lead-in motor 53 to the gear 542 is transmitted to the driven gear 540 to rotate the drive roller 52 .

In this configuration, the rotation direction of the driving roller 52 can be switched by switching the clutches to be engaged between the clutches C1 and C2. That is, as described above, the rotation directions of the gear 541 engaged with the clutch C1 and the gear 542 engaged with the clutch C2 are opposite. Therefore, the rotation direction of the drive roller 52 is switched between the case where the clutch C1 is engaged and the case where the clutch C2 is engaged. Specifically, the drive roller 52 rotates in the forward direction R1 when the clutch C1 is engaged, and the drive roller 52 rotates in the reverse direction when the clutch C2 is engaged.

Thus, the tape introduction mechanism 51 of the tape feeder 5 of 2nd Embodiment has two clutches C1, C2. The gear 584 (first rotating member) of the clutch C1 is rotated by the driving force of the lead-in motor 53 rotating in the normal direction, thereby rotating the driving roller 52 in the forward direction R1. On the other hand, the gear 584 (second rotating member) of the clutch C2 is rotated by the driving force of the lead-in motor 53 rotating in the forward direction, thereby causing the drive roller 52 to rotate in the reverse direction. And, switching of the rotation direction of the drive roller 52 between the forward direction R1 and the reverse direction R2 is performed by switching the transmission destination of the driving force introduced into the motor 53 between the gear 584 of the clutch C1 and the gear 584 of the clutch C2 .

The tape feeder 5 of the second embodiment also includes a tape introduction mechanism 51 that introduces the tape by transmitting the driving force generated by the single introduction motor 53 to the tape TP inserted into the tape insertion path P1, P2. TP. Furthermore, the tape introduction mechanism 51 can transmit the driving force of the driving roller 52 to the tape TP inserted into one of the tape insertion paths P1, P2 selected from the plurality of tape insertion paths P1, P2, so that it can pass between the plurality of tape insertion paths P1, P2. Alternately switch the tape insertion way to execute import with TP. Thereby, the number of objects of the introduction motor 53 can be suppressed, and the tape feeder 5 provided with the several tape insertion paths P1 and P2 for introducing the inserted tape TP can be comprised, suppressing cost increase.

Fig. 6 is a partial side view schematically showing a third embodiment of the tape feeder. The difference between the third embodiment and the first embodiment is mainly that the one-way sprockets 55a, 55b are set as a structure that can be approached or separated from the driving roller 52, and other structures are the same in the first embodiment and the third embodiment. . Therefore, the following description will focus on the points of difference from the first embodiment, and the description of the points in common with the first embodiment will be appropriately omitted. In addition, it goes without saying that the same effect can be exerted by having the same structure as that of the first embodiment.

In the tape feeder 5 of the third embodiment, solenoids S561 are respectively provided on the rod 561 that axially supports the one-way sprocket 55a and the rod 561 that axially supports the one-way sprocket 55b. The shaft Ss of each solenoid S561 is connected to the corresponding rod 561 . Further, each solenoid S561 can move the shaft Ss forward and backward to swing the lever 561 , thereby allowing the corresponding one-way sprockets 55 a and 55 b to approach or separate from the drive roller 52 .

Specifically, each solenoid S561 advances the shaft Ss to bring the corresponding one-way sprockets 55 a and 55 b close to the driving roller 52 , and can bring the belt TP into pressure contact with the driving roller 52 . In addition, each solenoid S561 can release the pressure contact of the belt TP to the driving roller 52 by moving the shaft Ss backward to separate the corresponding one-way sprockets 55 a and 55 b from the driving roller 52 .

And, in the case where the introduction of the tape TP is performed in the tape insertion path P1, the one-way sprocket 55a (first driven roller) is separated from the drive roller 52 while the one-way sprocket 55a (first driven roller) ) close to the drive roller 52. As a result, the belt TP is brought into pressure contact with the driving roller 52 to generate a frictional force between the driving roller 52 and the belt TP. When the driving roller 52 is rotated in the forward direction R1 in this state, the one-way sprocket 55 a is driven to rotate by the driving roller 52 and allows the movement of the tape TP in the tape insertion path P1 in the delivery direction D. In this way, the lead-in of the tape TP is executed in the tape insertion way P1.

In addition, since the one-way sprocket 55b is separated from the driving roller 52, even if the tape TP exists in the tape insertion path P2, frictional force cannot be ensured between the belt TP and the driving roller 52. Therefore, the tape TP in the tape insertion path P2 does not follow the rotation of the drive roller 52 . In this way, by releasing the pressure contact of the driving roller 52 of the belt TP in the belt insertion path P2 , the movement of the belt TP by the frictional force with the peripheral surface of the driving roller 52 is restricted. Thereby, the introduction of the tape TP in the tape insertion path P1 can be performed while suppressing the influence on the tape TP of the tape insertion path P2.

On the other hand, when the introduction of the tape TP is performed in the tape insertion path P2, the one-way sprocket 55b is brought close to the drive roller 52 while separating the one-way sprocket 55a from the drive roller 52, and the drive roller 52 is reversed. Just spin it. In this way, the introduction of the tape TP in the tape insertion path P2 can be performed while suppressing the influence on the tape TP of the tape insertion path P1.

Incidentally, in the third embodiment, the one-way sprockets 55 a , 55 b of the tape insertion path that do not introduce the tape TP are separated from the drive roller 52 . Therefore, even if sprockets rotatable in both directions are used instead of the one-way sprockets 55a and 55b, the movement of the belt TP can be appropriately restricted.

The tape feeder 5 of the third embodiment also includes a tape introduction mechanism 51 for introducing a tape by transmitting the driving force generated by a single introduction motor 53 to the tape TP inserted into the tape insertion path P1, P2. TP. Furthermore, the tape introduction mechanism 51 can transmit the driving force of the driving roller 52 to the tape TP inserted into one of the tape insertion paths P1, P2 selected from the plurality of tape insertion paths P1, P2, so that it can pass between the plurality of tape insertion paths P1, P2. Alternately switch the tape insertion way to execute import with TP. Thereby, the number of objects of the introduction motor 53 can be suppressed, and the tape feeder 5 provided with the several tape insertion paths P1 and P2 for introducing the inserted tape TP can be comprised, suppressing cost increase.

In addition, this invention is not limited to the said embodiment, Without deviating from the summary, various changes can be added to the said structure. For example, in the above-mentioned embodiment, the single tape introduction mechanism 51 is provided in the feeder main body 50 . However, a plurality of tape introduction mechanisms 51 may be provided in the feeder main body 50 , and the number of tape insertion paths twice the number of tape introduction mechanisms 51 may be provided accordingly. Even in this structure, in each tape introduction mechanism 51, by transmitting the driving force of the drive roller 52 to the tape TP inserted into one tape insertion path selected from the plurality of tape insertion paths P1, P2, it is possible to perform multiple The tape insertion way to perform the lead-in of the tape TP is switched alternately between the stripe insertion ways P1 and P2. Thereby, the number of objects of the introduction motor 53 can be suppressed, and the tape feeder 5 provided with the several tape insertion paths P1 and P2 for introducing the inserted tape TP can be comprised, suppressing cost increase.

In addition, in the above-described embodiment, the single drive roller 52 is commonly provided in the tape insertion paths P1, P2. However, the driving rollers 52 may be provided on the tape insertion paths P1 and P2 respectively.

In addition, the number of tape insertion paths P1 and P2 provided in the tape introduction mechanism 51 is not limited to the above example. Accordingly, three or more tape insertion paths may be provided in the tape introduction mechanism 51 .

In addition, the tape feeder 5 of the said example discharges a cover tape together with a carrier tape from discharge port A0, and discards it to the disposal box. However, for example, as in the tape feeder described in Japanese Patent Application Laid-Open No. 2000-91790, the cover tape may be peeled off from the carrier tape, separated from the carrier tape, and wound separately from the carrier tape at a place near the component supply position L. The tape feeder 5 is formed by winding the cover tape. When attaching the tape TP to the tape feeder 5, the front end of the tape TP may be automatically sent out to the position where the carrier tape is peeled off from the cover tape, and then the operator may peel off the cover tape at the front end of the tape TP and attach it. Winder for cover tape.
