Description

Rod Item Feeder

technical field

The present invention relates to a feeder for supplying rod-shaped articles such as filters used in manufacturing filter cigarettes to a consumption device.

Background technique

As disclosed in JP 60-177109 and JP 8-58972, the feeder is equipped with grooved rollers arranged up and down at the bottom of the hopper. And Japanese Patent Application Laid-Open No. 7-147963 discloses a single type feeder, which only has a grooved roller at the bottom of the hopper. In addition, filters which are stick-shaped articles are stored in the hopper.

Both forms of feeding machines take out the filter tips one by one from the hopper through the rotation of the grooved roller, and the removed filter tips are transferred on the grooved roller. In the subsequent transfer process, the filter is subjected to the discharge pressure of compressed air, discharged from the feeder into the transfer pipe, and then supplied to the filter cigarette making machine as a consumption device together with the compressed air flow through the transfer pipe.

More specifically, a plurality of extraction grooves are formed on the outer peripheral surface of the grooved cylinder, and these extraction grooves are arranged at equal intervals in the circumferential direction of the grooved cylinder. Along with the rotation of the grooved drum, each take-out groove enters the outlet of the hopper to receive the filter tip, and the received filter tip is taken out from the hopper. Then, when the take-out chute passes a predetermined corner position in the rotational direction of the grooved drum, a discharge pressure of compressed air is supplied to the take-out chute, and the discharge pressure discharges the filter in the take-out chute into the transfer pipe. That is, the discharge pressure of the compressed air continues to be supplied to the grooved drum. In addition, in the case of a compound feeder, the grooved roll to which the pressure is supplied and discharged is the lower grooved roll.

In recent years, as the operating speed of filter cigarette manufacturing machines has been increased, it has been demanded that the feeding speed of the filters of such feeding machines be increased even further.

In order to increase the speed of the feeder, it is first necessary to increase the peripheral speed of the grooved drum and at the same time increase the discharge pressure of the filter to a high pressure.

However, when the peripheral speed of the grooved drum is high, the removal of the filter tip from the hopper becomes unstable. In more detail, once the peripheral speed of the grooved drum becomes high, the moving speed of the taking-out groove also becomes faster, and for this moving speed, the speed at which the filter tip falls into the taking-out groove cannot keep up. As a result, the receiving filter of the take-out tank fails and leaves the outlet of the hopper in an empty state.

For eliminating above-mentioned bad situation, on the feeder disclosed in Japanese Unexamined Publication No. 60-177109, the jet hole that sprays compressed air toward the outer peripheral surface of the grooved drum is equipped with, and this jet hole is contained on the sidewall of hopper one side. Here, the side wall on one side refers to the side wall located upstream in the direction of rotation of the grooved drum among the two side walls of the hopper.

When the compressed air is ejected from the above-mentioned jet holes, the compressed air flow will forcefully push the filter tip in the hopper to the grooved drum, that is, the take-out groove thereon. Though this pushing down to filter tip has accelerated the falling speed of filter tip to taking-out groove, only rely on to utilize compressed air to improve falling speed and not be enough to deal with the high-speed rotation of band grooved cylinder.

More specifically, in the case of the above-mentioned feeder, the lower portion of the side wall on one side of the hopper is inclined toward the grooved roller, and the slope of the lower portion is relatively gentle. Specifically, the lower portion of one side wall is inclined at an angle of 30° relative to the horizontal plane. Therefore, the row of filters contacting the lower part of one side wall is actually supported by the lower part of one side wall, and bears the entire weight of the filters stacked on the upper part. Therefore, even if the ejection pressure of the above-mentioned compressed air is applied to a row of filter tips, the flow rate of the filter tips to the take-out groove cannot be very fast.

On the other hand, even if the filter tip is received by the take-out groove, the receiving posture of the filter tip is unstable due to the high-speed rotation of the grooved drum. That is, the filter tip is easily received by the take-out groove in an inclined state.

Once the filter tip is tilted in the take-out tank, in the case of the aforementioned compound feeder, the transfer of the filter tip from the upper grooved drum to the lower grooved drum is unstable, and in the case of a single feeder, Then the filter tip cannot allow its end face to receive the ejection pressure of the compressed air correctly in the axial direction of the filter tip. As a result, the filter cannot be discharged stably, and clogging of the filter is likely to occur between the extraction tank and the transfer pipe.

And the known feeder no matter what kind of form, has all adopted the device that reduces the rotational resistance of band grooved drum, has adopted the structure that band grooved drum is non-contact state support to box body, and this support structure ensures that the two end faces of band grooved drum There are gaps between the box body and the outer peripheral surface of the grooved roller and the box body.

In the support structure of the grooved roller, the size of the above-mentioned respective gaps is greatly affected by the machining accuracy and assembly accuracy of parts, and it is very difficult to accurately maintain the respective gaps at desired sizes. Therefore, when high-pressure discharge pressure is intermittently supplied to the grooved roll, high-pressure compressed air leaks intermittently through the above-mentioned gap, and this leakage causes the grooved roll to vibrate in its radial direction and axial direction. The vibration of the grooved roller causes interference between the grooved roller and the housing, possibly making the grooved roller unable to rotate.

Contents of the invention

An object of the present invention is to provide a rod-shaped article feeder capable of maintaining stable take-out of the rod-shaped article from a hopper and stably discharging the rod-shaped article while increasing the supply speed of the rod-shaped article.

In order to achieve the above object, the rod-shaped article feeding machine of the present invention includes as a premise: a hopper for storing the rod-shaped articles; an upper roller having an outer peripheral surface capable of closing the outlet of the hopper and rotating in one direction, and on the outer peripheral surface of the upper roller, along the There are multiple take-out grooves arranged at equal intervals in the circumferential direction of the upper roller. These take-out grooves follow the rotation of the upper roller and pass through the outlet of the hopper. The lower drum is set adjacent to the upper drum, and its rotation direction is opposite to that of the upper drum. On the outer peripheral surface of the lower drum, there are multiple transfer grooves arranged at equal intervals along the circumferential direction of the lower drum. These transfer grooves follow the The rotation of the lower roller is aligned with the take-out groove of the upper roller in sequence, and the rod-shaped articles are received from the take-out groove and transferred; the box is arranged outside the lower roller to support the lower roller and make it rotate freely. There is a discharge port on the top, and the discharge port can be connected with one end of the transfer trough in sequence with the rotation of the lower roller; the transfer pipe is connected with the discharge port and is the transfer guide for rod-shaped objects; the compressed air injection device is connected between the transfer trough and the discharge port. When the outlet is connected, the compressed air is sprayed to the other end of the transfer tank, and the rod-shaped objects in the transfer tank are discharged into the transfer pipe through the discharge port.

That is, the present invention is applied to the aforementioned multiple feeder, and has various features described below.

The feeder of the present invention includes a device capable of forming a row of rod-shaped articles flowing down toward the outer periphery of the upper drum in the hopper, and increasing the flow-down speed of the row.

Specifically, the hopper has a side wall located on the upstream side according to the rotation direction of the upper drum. At this time, the above-mentioned device includes: a lower inclined part, which forms the lower part of one side wall, and the lower inclined part maintains a first oblique angle with the outer peripheral surface of the upper drum and extends upward. The first oblique angle is between 1/2 and Within the range of 3/4 right angle; the upper inclined part, which forms the upper part of one side wall and is directly or indirectly connected with the lower inclined part, and the upper inclined part has a second inclined angle, which ranges between the right angle and the first inclined angle; The jet hole is located on one side wall, and jets compressed air toward the outer peripheral surface of the upper drum along the lower slope.

In the above feeder, since the first inclination angle of the lower inclined portion of one side wall is set within the range of 1/2 to 3/4 right angle, the inclination of the lower inclined portion is relatively sharp. Therefore, the row of rod-shaped articles in contact with the lower inclined portion flows down rapidly along the lower inclined portion, and the flow-down speed of the row is increased. Furthermore, since the column of rod-shaped articles receives the compressed air ejected from the air injection hole, the flow-down velocity of the column is further accelerated. Therefore, along with the rotation of the upper drum, as soon as each extraction slot of the upper drum enters the outlet of the hopper, the bar-shaped article at the lowest position in the aforementioned row is immediately attracted by the extraction slot, and is quickly accepted into the extraction slot.

Moreover, the second bevel angle of the upper slant portion of one side wall is sharper than the first bevel angle of the lower slant portion, so the stick-shaped article in contact with the upper slant portion can not only flow down the lower slant portion rapidly, but also flow down The direction does not deviate greatly from the lower sloped portion either. Therefore, the stick-shaped articles in the hopper flow smoothly toward the lower inclined portion, and stably form a row of stick-shaped articles along the lower inclined portion.

As a result, the rod-shaped articles in the hopper are reliably received by the take-out grooves of the upper drum, so that the rotation speed of the upper drum can be increased.

In the feeder of the present invention, each take-out groove of the upper drum may have a suction hole for sucking rod-shaped articles only in the center of the groove direction. At this time, even if the rod-shaped article is received by the take-out groove in an unstable posture, the rod-shaped article is only sucked by the center (attraction hole) in the groove direction in the take-out groove. Therefore, after that, during the movement of the rod-shaped items in the outlet of the hopper together with the extraction tank, the rod-shaped items will completely fall into the extraction tank by rotating around the adsorption position as the center due to contact with other rod-shaped items in the hopper. The pose is accepted by the removal slot.

As a result, even if the receiving posture of the rod-shaped article is unstable, the receiving posture can be corrected, so high-speed rotation of the upper drum becomes possible.

In the feeder of the present invention, the box body may include: an outer peripheral guide that surrounds the outer periphery of the lower roller; a pair of end walls that are arranged to hold both ends of the lower roller; The upper part supports the roller shafts of the lower roller respectively, and allows the lower roller to move along its axial direction; the pressing device pushes the lower roller to one side of the axial direction; the adjusting device resists the pushing force of the pressing device to make the lower roller Move to the other side of the axial direction to adjust the gap between one end wall and the lower drum located on the other side of the axial direction. In addition, the compressed air injection device may include: a cylindrical member fitted in the other end wall and kept airtight It rotates integrally with the lower roller, and the cylindrical member can move along its axis relative to the other end wall; the communication holes are formed in the cylindrical member and communicate with the transfer grooves of the lower roller respectively, and each communication hole has The opening opened on the outer peripheral surface of the cylinder member; the supply port, formed on the other end wall, communicates with the openings of the communication holes sequentially with the rotation of the lower drum, and receives the supply of compressed air.

In the above box, since the lower roller can move along the axial direction, the gap between one end wall of the box and the lower roller can be most properly adjusted by the adjusting device.

The lower drum is in a thrust state due to the pressure device, so the bearing device, specifically the deep groove ball bearing, gives firm support to the drum shaft of the lower drum in the axial direction and in the radial direction.

On the other hand, in the above-mentioned compressed air spraying device, the cylindrical member is located at the other end wall of the box body and is airtightly fitted in the other end wall, so there is no compression in the path connecting the supply port and the transfer tank. Gap for air leaks. Therefore, even if the compressed air intermittently injected into each transfer tank through the supply port is at high pressure, the leakage of the compressed air is greatly reduced. As a result, vibration of the lower drum is suppressed, and high-speed rotation of the lower drum becomes possible.

In the feeder of the present invention, the hopper further includes: the other side wall is located on the downstream side according to the rotation direction of the upper drum; Rotate in the same direction; adjust the device to adjust the gap between the upper roller and the lifting roller. At this time, with the rotation of the upper drum, when the take-out trough leaves the outlet of the hopper, the pull-up roller pushes other stick-like items adjacent to the stick-like items in the take-out trough upward, so that the take-out of the stick-like items from the hopper is smooth. Moreover, the gap between the pick-up roller and the upper cylinder can be adjusted according to the diameter of the rod-shaped article, avoiding the contact of the rod-like article in the take-out groove with the pick-up roller, and preventing the stick-like article from being bitten between the pick-up roller and the take-out groove. In this way, the high-speed rotation of the upper drum becomes possible since the stable removal of the rod-shaped articles is ensured.

In the feeder of the present invention, the groove depth and spacing of the take-out chute should be set according to the rod-shaped articles in the hopper that have been accepted by the take-out chute to prevent other rod-shaped articles in the hopper from contacting the upper roller. In this way, even if the rotation speed of the upper drum is increased, the upper drum will not damage the rod-shaped article due to contact with the rod-shaped article, which also contributes to the high-speed rotation of the upper drum.

Detailed ways

Fig. 1 shows a filter cigarette manufacturing system equipped with a feeding machine of the present invention. The manufacturing system includes: a plurality of filter cigarette manufacturing machines, so-called filter attachments 2 ; filter feeders 4 ; Each feeder 4 supplies a filter into the filter hopper of the corresponding filter attachment 2 through the transfer pipe 6 .

Here, the filter attachment 2 receives not only the filters supplied from the corresponding supply machine 4 but also the supplied cigarette rods manufactured by the cigarette manufacturing machine, and manufactures these cigarette rods and filters into filter cigarettes.

As shown in FIG. 2 , the feeder 4 is equipped with a hopper 8 storing a plurality of filter tips F (hereinafter, simply referred to as sticks F). The lower end of the hopper 8 has an outlet, which is blocked by the upper drum 10 . The upper drum 10 is a grooved drum, and a plurality of extraction grooves 12 are provided on the outer peripheral surface of the upper drum 10 . The take-out grooves 12 are arranged at regular intervals in the circumferential direction of the upper drum 10 .

The upper drum 10 rotates counterclockwise as shown by arrow A in FIG. 2 . Therefore, with the rotation of the upper drum 10, the take-out chute 12 enters into the outlet of the hopper 8 and can receive the filter tips F in the hopper 8 one by one.

The hopper 8 has: a side wall 14 positioned at the turning-in side when the upper drum 10 rotates, that is, located at the upstream side for the rotation direction of the upper drum 10; a side wall 16 positioned at the turning-out side when the upper drum 10 rotates , that is, located on the downstream side of the upper drum 10 . The outlet width of the hopper 8 , that is, the outlet width along the rotation direction of the upper drum 10 is limited by the lower ends of the side walls 14 , 16 .

The inner wall surface of the side wall 14 has a lower inclined portion 18 from the upper drum 10 , a vertical portion 20 , and an upper inclined portion 22 . The lower inclined portion 18 has a first inclination angle θ ₁ in the range of 1/2˜3/4 right angle to _the horizontal plane. Specifically, the first bevel angle θ ₁ is, for example, 60°.

The _upper sloped portion 22 has a second slope angle θ ₂ that is larger than the first slope angle θ ₁ . For example, the second oblique angle _θ2 is an angle between 90° and the first oblique angle _θ1 , specifically, 76°.

The vertical part 20 is then arranged as required. Therefore, no vertical portion 20 is required. At this time, the upper inclined portion 22 is directly connected to the lower inclined portion 18 .

In addition, there is no special requirement on the slope of the inner wall surface of the side wall 16 . However, the inner wall surface of the side wall 16 preferably has the same inclination as the first inclination angle _θ1 of the lower inclined portion 18.

Also, the vertical portion 20 has a plurality of air injection holes 24 arranged at predetermined intervals in the depth direction of the hopper 8 , that is, in the axial direction of the rods F in the hopper 8 . Each air injection hole 24 communicates with an air supply passage 26 , and the air supply passage 26 extends inside the side wall 14 . The air supply passage 26 is connected with the air pressure source outside the hopper 8 . As clearly shown in FIG. 2, each gas injection hole 24 is inclined at the same inclination as that of the lower inclined portion 18. As shown in FIG. Therefore, the compressed air injected from each air injection hole 24 flows along the lower inclined portion 18 .

Simultaneously, hopper 8 has a plurality of pick up rollers 28, and these pick up rollers 28 are blocked between the lower end of side wall 16 and the outer periphery of upper drum 10 with a part of its outer peripheral surface, and with upper drum 10 same direction, promptly according to figure 2 in the counterclockwise direction.

The pick-up roller 28 can move towards the direction approaching the upper drum 10 and the direction away from the upper drum 10 . The movement of this pick-up roller 28 can adjust the gap between the pick-up roller 28 and the upper drum 10, in other words, it can adjust the gap E between the pick-up roller 28 and the filter tip F that has been accepted by the take-out groove 12, the gap E Adjust according to the diameter of rod F. Specifically, when the diameter of the rod F is 8 mm, the gap E is preferably set to about 1.8 mm.

Figure 3 shows the adjustment mechanism for the gap E.

As shown in FIG. 3, the pick-up rollers 28 are mounted on roller shafts 30 at regular intervals. One end of the roller shaft 30, that is, the left end of the roller shaft 30 in FIG. For this reason, there is a hole 34 that can accommodate the roller shaft 30 to pass through on the frame 32 , and a required annular gap is ensured between the inner circular surface of the hole 34 and the roller shaft 30 .

The mounting plate 38 is fastened to the frame 32 by a plurality of mounting bolts 40 . More specifically, there are insertion holes 42 on the mounting plate 38 that can accommodate the mounting bolts 40 , and these insertion holes 42 are distributed in an arc shape along the circumferential direction of the mounting plate 38 . Therefore, each mounting bolt 40 is screwed into the frame 32 through the insertion hole 42 on the mounting plate 38 .

In addition, the other end of the roller shaft 30 is connected to one end of the drive shaft 46 through a coupling 44 . The drive shaft 46 extends through a hollow shaft 48 . Both ends of the hollow shaft 48 support the drive shaft 46 through bearings 50 to allow it to rotate freely. The hollow shaft 48 itself is rotatably supported on the frame 32 , the outer circumference of the hollow shaft 48 is eccentrically facing the drive shaft 46 .

The other end of the drive shaft 46 is provided with a pulley 52 . The pulley 52 is connected to a drive pulley (not shown) through an endless belt 56 , and the drive pulley is mounted on the output shaft of the variable speed motor 54 . Thereby, once motor 54 is driven, the driving force of motor 54 is just transmitted on the respective pick-up rollers 28 by drive shaft 46 and roller shaft 30, thus, these pick-up rollers 28 are with the same direction with upper cylinder 10 by the prescribed speed. turn. Specifically, the peripheral speed of the pick-up roller 28 is adjusted according to the diameter of the rod F. This adjustment is performed by varying the rotational speed of the motor 54 .

Rotate the hollow shaft 48 in the state where the fastening of the aforementioned mounting plate 38 is released, then since the outer peripheral surface of the hollow shaft 48 is eccentric with respect to the drive shaft 46, as shown in FIG. displacement along its radial direction. As a result, the gap E between each lifting roller 28 and the upper roller 10 is adjusted.

In addition, in FIG. 2 , the extraction grooves 12 of the upper drum 10 are seen to be continuous in the axial direction of the upper drum 10 . However, when seen from the vertical cross-sectional view of the upper drum 10 shown in FIG.

At the center of the upper drum 10 is mounted a drum shaft 58 . The roller shaft 58 penetrates the upper roller 10 and is integrally connected with the upper roller 10 by a key 59 . The key 59 is mounted on one end of the upper drum 10 .

The two ends of the drum shaft 58 are supported on the frame 32 through bearings 60 and are free to rotate. One end of the drum shaft 58 is equipped with a gear 62, and the drum shaft 58 can receive a driving force from the other end. Therefore, when a driving force is input to the other end of the drum shaft 58, the upper drum 10 rotates at a predetermined speed, that is, a predetermined peripheral speed.

The bottom of the central portion 12b of each extraction groove 12 has a suction hole 64 which communicates with an axial hole 66 in the upper drum 10 . More specifically, as shown in FIG. The open ends of the axial holes 66 are equally spaced on the same distribution circle.

The other end surface of the upper drum 10 is provided with a control ring 68 which has a contact surface in airtight contact with the upper drum 10 . A control ring 68 surrounds the drum shaft 58 and is fixed to the frame 32 . That is, when the upper drum 10 rotates, the other end surface of the upper drum 10 is in relative sliding contact with the control ring 68 .

An arc-shaped suction groove 70 is formed on the contact surface of the control ring 68 as shown in FIG. 7 . The suction groove 70 has about the same radius of curvature as the distribution circumference of the aforementioned axial holes 66 and extends approximately half the circumference of the control ring 68 . Therefore, when the upper drum 10 rotates, the opening ends of the axial holes 66 communicate with the suction grooves 70 in sequence.

The suction groove 70 communicates with an axial hole 72 in the control ring 68 . The axial hole 72 is connected to an external suction pipe 76 through an internal passage (not shown) in the connecting ring 74, and the suction pipe 76 is connected to a negative pressure source. The connection ring 74 is disposed adjacent to the control ring 68 and is a fixing member similarly to the control ring 68 .

Accordingly, the negative pressure source continuously supplies a predetermined suction pressure into the suction groove 70 of the control ring 68 . When the suction groove 70 is in the state where the axial hole 66 of the upper drum 10 communicates with the suction groove 70, in other words, when the axial hole 66 is in the suction area S (referring to FIGS. Suction pressure is supplied to the suction hole 64 of the corresponding extraction tank 12 .

Here, as shown in FIG. 2 , the suction area S is the region beyond the outlet of the hopper 8 from the position in front of the side wall 14 of the hopper 8 according to the rotation direction of the upper drum 10 , that is, it extends about half a circle of the upper drum 10 .

The bottom of upper drum 10 is equipped with lower drum 78, which can be switched with upper drum 10. The lower drum 78 can rotate clockwise as shown by arrow B in FIG. 2 in the opposite direction to the upper drum 10 .

A plurality of transfer grooves 80 are provided on the outer periphery of the lower drum 78 , and these transfer grooves 80 are arranged at equal intervals in the circumferential direction of the lower drum 78 . When the upper drum 10 and the lower drum 78 rotated together, the take-out groove 12 and the transfer groove 80 were aligned with each other at the switching positions of the upper drum 10 and the lower drum 78 .

The outer side of the lower drum 78 is equipped with a casing 82, which wraps the lower drum 78 from three directions. More specifically, the box body 82 includes: a peripheral guide 84 partially covering the peripheral surface of the lower drum 78 ; end walls 88 , 90 respectively covering both ends of the lower drum 78 as shown in FIG. 5 . These end walls 80, 90 support the roller shaft 86 of the lower roller 78, and the roller shaft 86 is free to rotate. The outer peripheral guide 84 covers the lower half of the lower roller 78 , and a predetermined gap is secured between the outer peripheral guide 84 and the lower roller 78 . Therefore, there is no sliding contact between the rotation of the lower roller 78 and the outer peripheral guide 84 .

As shown in FIG. 8 , the outer peripheral guide 84 is composed of half a hollow cylinder, and the two ends of the outer peripheral guide 84 are respectively provided with end walls, and these end walls are used to support the outer peripheral guide 84 on the frame 32 . Specifically, one end wall of the outer peripheral guide 84 is connected to the end wall 88 , and the other end wall of the outer peripheral guide 84 is supported on the frame 32 .

End wall 88 supports one end of roller shaft 86 via deep groove ball bearing 92, allowing it to rotate freely. Here, the deep groove ball bearing 92 is fixed to the drum shaft 86 and not fixed to the end wall 88 . The deep groove ball bearing 92 is thus slidable with the roller shaft 86 relative to the end wall 88 in the axial direction of the roller shaft 86 .

One end of the roller shaft 86 protrudes from the end wall 88 . Hollow shaft 96 is contained in an end of drum shaft 86 by key 94, and gear 98 is arranged on this hollow shaft 96. The gear 98 meshes with the gear 62 of the upper drum 10 , whereby the lower drum 78 receives the driving force from the upper drum 10 and rotates in conjunction with the rotation of the upper drum 10 .

Spacers 100 are mounted in end wall 88 via mounting plate 99 . The gasket 100 is wave-shaped as shown in FIG. 9 , and is mounted on the same shaft as the deep groove ball bearing 92 . And between the gasket 100 and the deep groove ball bearing 92, an extruded sleeve 102 is arranged. The spacer 100 presses the deep groove ball bearing 92 against one end face of the lower roller 78 by pressing the sleeve 102 . Therefore, the lower roller 78 is constantly pushed toward the other side end wall 90 by the spacer 100 .

An annular hole 103 is also formed on the end wall 88 , and the annular hole 103 has an opening facing one end surface of the lower drum 78 . An air flange 104 is embedded in the annular hole 103 . More specifically, the air flange 104 is cup-shaped, and is composed of an open end fitted into the annular hole 103 and an end wall in contact with one end surface of the lower roller 78 . The end wall of the air flange 104 is fixed on one end surface of the lower drum 78 , so the air flange 104 and the lower drum 78 rotate integrally. When the air flange 104 rotates, the outer peripheral surface of the air flange 104 is in airtight sliding contact with the large-diameter inner peripheral surface of the annular hole 103 , and the air flange 104 can move freely along the axial direction of the annular hole 103 .

As can be seen from FIG. 10 , a plurality of communication holes 106 are formed in the peripheral wall of the air flange 104 , and these communication holes 106 are arranged at equal intervals in the circumferential direction of the air flange 104 . These communicating holes 106 penetrate through the end wall of the air flange 104 and always communicate with the corresponding transfer grooves 80 of the lower roller 74 .

A plurality of input ports 108 are opened on the outer peripheral surface of the air flange 104 . These input ports 108 are arranged at equal intervals in the circumferential direction of the air flange 104 and communicate with corresponding communication holes 106 .

On the other hand, a supply port 110 is formed in the end wall 88 . As the lower roller 78 rotates, when each transfer chute 80 passes a predetermined corner position, that is, a discharge position, the supply port 110 communicates with the input port 108 and the communication hole 106 corresponding to the transfer chute 80 .

As is clear from FIG. 2 , the supply port 110 is located in a region where the lower roller 78 is covered by the aforementioned outer peripheral guide 84 in terms of the circumferential direction of the lower roller 78 . The supply port 110 is connected to a compressed air supply pipe 114 through a joint 112 which is fixed on the outside of the end wall 88 . The compressed air supply pipe 114 is connected to a compressed air source through a solenoid valve 116 .

As shown in FIG. 5 , the end wall 90 includes a cylinder head 118 , and the cylinder head 118 is arc-shaped. That is, as shown in FIG. 11 , the cylinder head 118 has an arcuate shape opened upward, and is supported by the above-mentioned frame 32 .

A bearing seat 120 is housed in the cylinder head 118, and the bearing seat 120 starts from the lower roller 78, that is, from one end surface thereof, accommodates a needle roller bearing 124, a deep groove ball bearing 126 and an extruding plate 130 in sequence. The needle bearing 124 rotatably supports the roller shaft 86 in a state that allows the roller shaft 86 to move in the axial direction. The deep groove ball bearing 126 is the same as the aforementioned deep groove ball bearing 92 , fixed on the drum shaft 86 , but not fixed with respect to the bearing housing 120 . Therefore, the deep groove ball bearing 126 can slide in the axial direction of the bearing housing 120 . The extrusion disc 130 can freely slide along the axial direction of the roller shaft 86 in the bearing housing 120 .

The other end of the bearing housing 120 is screwed with an adjusting bolt 128 arranged on the same axis as the drum shaft 86 . One end of the adjusting bolt 128 protrudes from the bearing seat 120 , and squeezes the deep groove ball bearing 126 through the pressing disc 130 . Thus, the adjusting bolt 128 can push the lower roller 78 back against the pushing force of the aforementioned washer 100 on the lower roller 78 .

To elaborate on this point, just after the feeder 4 is assembled, the lower roller 78 receives the thrust generated from the gasket 100, so the other end surface of the lower roller 78 is in contact with the end wall 90, that is, with the cylinder head 118 and the bearing. A state in which one end surface of the seat 120 is in close contact. Such a close contact state increases the rotational resistance of the lower roller 78 , which is disadvantageous in increasing the rotational speed of the lower roller 78 .

However, afterwards, the adjustment bolt 128 is further screwed in, and when the lower roller 78 is pushed back through the squeeze plate 130 and the deep groove ball bearing 126, the other end surface of the lower roller 78 and the cylinder head 118 and the bearing seat 120, in other words, The desired gap G is ensured between the lower roller 78 and the end wall 90 accurately and easily. Here, the gap G does not increase the rotational resistance of the lower drum 78 , and a sufficient gas seal is established between the lower drum 78 and the end wall 90 .

As shown in FIG. 11 , an arc-shaped discharge port 132 is formed at the lower portion of the cylinder head 118 . The discharge port 132 extends a predetermined length in the circumferential direction of the lower drum 78 and communicates with the discharge port 132 when the transfer chute 80 of the lower drum 78 passes through the aforementioned discharge position.

A connection nozzle 134 is connected to the other end surface of the cylinder head 118 . As shown in FIG. 12 , the connection nozzle 134 has the same arc shape as the cylinder head 118 and has an arc-shaped long hole 136 . The circular arc long hole 136 coincides with the discharge port 132 . The circular arc long hole 136 is connected to a nozzle portion 138 having a flat funnel shape, one end overlapping with the circular arc long hole 136 and the other end connected to the transfer pipe 6 .

Referring again to FIG. 2 , the outer side of the lower drum 78 is provided with a transition guide 140 . The transition guide 140 extends toward the upper drum 10 from the upper end 84a of the outer peripheral guide 84 on the upstream side in terms of the rotation direction of the lower drum 78 . The base of the transition guide 140 constitutes an extension of the outer peripheral guide 84 and covers the outer peripheral surface of the lower drum 78 . Moreover, the top end of the transition guide 140 is comb-shaped, and the teeth on the top end are sandwiched between the slots of the take-out slots 12 of the upper drum 10 . More specifically, as shown in FIG. 13, the top end of the transition guide 140 has four teeth 140a, and these teeth 140a are symmetrically arranged around the central groove portion 12b of the extraction groove 12, that is, the suction position X of the rod F. And the transition guide piece 140 is fixed on the outer peripheral guide piece 84 .

In addition, a transition guide 142 is also arranged on the outer side of the upper drum 10. According to the rotation direction of the upper drum 10, the transition guide 142 starts from the downstream end of the aforementioned suction area S toward the lower drum 78 and along the upper drum 78. The outer circumference of the drum 10 extends.

Next, the operation and function of the above-mentioned feeder 4 will be described.

Fig. 14～Fig. 16 has represented in turn along with the rotation of top drum 10, and its one empty take-out groove 12 enters the process till entering in the outlet of hopper 8 completely from beginning to enter.

As can be seen from FIG. 16 , as soon as the empty take-out tank 12 enters the outlet of the hopper 8 completely, the take-out tank 12 immediately accepts the stick F in the hopper 8, and the stick F is adsorbed by the adsorption hole 64 of the take-out tank 12 . The sticks F then exit from the outlet of the hopper 8 together with the take-out chute 12 and are transferred to the lower drum 78 .

Here, when the compressed air is sprayed from the air injection hole 24 of the side wall 14 of the hopper 8 along the lower inclined portion 18 of the side wall 14, the compressed air forces the rod row of the rods F in contact with the lower inclined portion 18 upwardly. The outer peripheral surface of the drum 10 flows down.

On the other hand, since suction pressure is supplied to the suction hole 64 of the extraction groove 12 immediately entering the outlet of the hopper 8, the extraction groove 12 attracts the lowest rod F in the row of rods. Accordingly, the lowest rod F is given a speed of rapidly flowing down to the extraction groove 12 . As a result, the rod F at the lowest position is quickly received by the take-out groove 12 and is reliably adsorbed by the suction hole 64 , that is, the take-out groove 12 .

And because the first inclination angle θ ₁ of the lower inclined portion 18 is within the 1/2～3/4 right angle range as mentioned above, that is, it is set to 60°, so the aforementioned rod row and stacked on the rod row The weight of the lowest stick F does not have an excessive influence on the lowest stick F. As a result, the row of rods is jetted by the compressed air from the air jet hole 24 to flow down the take-out groove 12 of the upper drum 10 smoothly and quickly.

Since the upper inclined portion 22 also has a second inclined angle θ ₂ , even if the rods F in the hopper 8 are piled up until the upper inclined portion 22 is fully charged, the upper inclined portion 22 can also support the upper inclined portion 22 to a certain extent. The weight of the upper stacked rods of the upper stack, which will not have an undue influence on the aforementioned row of rods.

And because the inclination of the second oblique angle θ ₂ of the upper inclined portion 22 is between the right angle and the first oblique angle θ ₁ , that is, there is a steeper inclination than the first oblique angle θ ₁ , so the above-mentioned upper stacking rod The flow down direction does not go away from the lower inclined portion 18 .

Therefore, during the process in which each rod F in the aforementioned row of rods is sequentially received by the take-out groove 12, the upper stacked rods are smoothly guided to the lower inclined portion 18 and stably form the aforementioned row of rods along the lower inclined portion 18.

As a result, even if the rotational speed of the upper drum 10 is increased, the take-out trough 12 can reliably receive the rod F immediately after entering the outlet of the hopper 8 . Therefore, all the take-out slots 12 that have entered the outlet of the hopper 8 leave the outlet of the hopper 8 in the state that the rods F have been received, so the removal of the rods F from the hopper 8 is stable.

Since only one suction hole 64 is provided in the center of each extraction groove 12, even if the rod F is adsorbed by the extraction groove 12 in an oblique posture, the rod F can rotate around the suction position. Therefore, the unstable posture of the rod F received by the take-out groove 12 in an unstable posture is corrected due to contact with other rods F in the hopper 8 in the subsequent transfer process until it leaves the hopper outlet, and is reliably recovered. Take out slot 12 accepted.

In addition, when the stick F is taken out from the outlet of the hopper together with the take-out groove 12, the pull-up roller 28 of the hopper 8 pushes other sticks F adjacent to the stick F in the take-out groove 12 upward, so that the stick F can be taken out smoothly. At this time, due to ensuring the specified gap E between the rod F in the roller 28 and the take-out groove 12, interference can not occur between the rod F and the roller 28. That is, even if the cross-section of the rod F is not a perfect circle, the rod F will not be bitten between the pick-up roller 28 and the take-out groove 12, so that the rod F can be taken out stably.

Furthermore, as shown in FIG. 17 , when the take-out groove 12 moves in the outlet of the hopper 8 , the rods F in the take-out groove 12 prevent other rods F in the hopper 8 from contacting the outer periphery of the upper drum 10 .

That is, the groove depth and the pitch interval of the extraction groove 12 are set appropriately, and the contact between the aforementioned other rods F and the outer periphery of the upper drum 10 is prevented. For example, in order to reduce the diameter of the upper cylinder 10 and set the pitch interval of the extraction groove 12, that is, when setting the interval between the extraction grooves 12 according to the radius of the rod F, the groove depth of the extraction groove 12 is 55-55% of the diameter of the rod F. 60% setting, like this just can reliably prevent the contact between aforementioned other bar F and the outer periphery of upper drum 10.

As shown by the two-dot chain line in FIG. 17, if the groove depth of the extraction groove 12 becomes deeper, the aforementioned other rods F may come into contact with the outer periphery of the upper drum 10. As shown in FIG. Such contact will increase the contact damage of the rod F with the upper drum 10 as the rotation speed of the upper drum 10 increases. However, in this embodiment, since the contact between the rod F and the upper drum 10 is avoided, the rod F will not be damaged.

The rod F taken out from the hopper 8 as described above advances with the rotation of the upper drum 10 and is transferred to the lower drum 78 . Thereafter, when the rod F leaves the above-mentioned suction area S, the suction pressure is not supplied to the suction hole 64 of the extraction groove 12 of the rod F, and at this point, the suction to the rod F is released. But at this time, since the transition guide 142 is arranged on the outer side of the upper drum 10 , the rod F does not fall off from the take-out groove 12 , but is transferred toward the lower drum 78 .

When the rod F arrives at the lower roller 78 and the removal groove 12 of the rod F is aligned with the transfer groove 80 of the lower roller 78, the rod F moves from the removal groove 12 to the transfer groove 80 while being guided by the transition guide 140, and then, along with the lower With the rotation of the drum 78, the rod F is continuously transferred.

As described above, the tip of the transition guide 140 has a comb shape that is bilaterally symmetrical about the suction position of the rod F. Therefore, the transition guide 140 stabilizes the transfer of the rod F from the extraction tank 12 to the transfer tank 80 .

Afterwards, when the transfer chute 80 that received the rod F reaches the aforementioned discharge position, the inlet 108 of the air flange 104 that is paired with the transfer chute 80 of the rod F communicates with the supply port 110 of the end wall 88 . At this time, the solenoid valve 116 is opened, and high-pressure compressed air is supplied into the compressed air supply pipe 114 . Accordingly, high-pressure compressed air is ejected into the transfer tank 80 located at the discharge position through the communication hole 106 of the air flange 104 . The compressed air discharges the rods F in the transfer tank 80 into the transfer pipe 6 through the discharge port 132 of the cylinder head 118 and the connecting nozzle 134, and then, the discharged rods F are transferred together with the compressed air flow to the corresponding cylinder through the transfer pipe 6. Filter attachment 2.

Here, as mentioned above, the lower roller 78 is thrust along its axis due to the pressure of the gasket 10, and the deep groove ball bearings 92, 126 on both sides of the lower roller 78 hold the roller shaft 86 in its axial direction and radial direction. firmly supported in both directions.

Moreover, the lower roller 78 can move along its axial direction, and the axial position of the lower roller 78 can be adjusted by the screw-in amount of the aforementioned adjusting bolt 128 . Therefore, the gap G between the lower roller 78 and the end wall 90 can be properly set, so that even if high-pressure compressed air is sprayed into the transfer tank 80, the high-pressure compressed air will not leak a large amount from the aforementioned gap G. Moreover, since the end wall 90 does not contact the lower roller 78 , the end wall 90 will not greatly increase the rotational resistance of the lower roller 78 .

The lower roller 78 is supported on the end wall 88 through the cylindrical air flange 104 and can rotate freely, so the end wall 88 will not increase the rotational resistance of the lower roller 78 . As a result, it becomes possible to rotate the lower drum 78 at a high speed. Furthermore, the air flange 104 can easily establish an airtight seal between the end wall 88 and the lower drum 78 .

And the gap between the lower roller 78 and the outer peripheral guide 84 can be set to a required value by adjusting the shaft cores of the lower roller 78 and the outer peripheral guide 84, and the lower roller 78 does not contact the outer peripheral guide 84.

As a result, as described above, both the upper drum 10 and the lower drum 78 can rotate at a high speed, so that the feeding speed of the rods F of the feeding machine 4 can be increased.

In addition, even if high-pressure compressed air is sprayed intermittently into each transfer groove 80 of the lower drum 78 , there is little leakage of the high-pressure compressed air from the lower drum 78 . The consumption of compressed air is thus reduced. Moreover, the roller shaft 86 of the lower roller 78 is firmly supported by the deep groove ball bearings 92, 126 in a thrust-bearing state, so the intermittent ejection of compressed air will not cause the lower roller 78 to vibrate back and forth, left and right.

The jetting of high-pressure compressed air shortens the time required for the sticks F to be discharged from the lower drum 78 to the cylinder head 118 . Therefore, not only the clogging of the rod F between the lower roller 78 and the cylinder head 118 is reliably prevented, but also the transfer distance of the rod F from the feeder 4 is significantly extended.

Although the present invention has been described as a feeder suitable for supplying the filter F to the filter attachment 2, it can be similarly applied to other stick-shaped article feeders other than filters.

In addition, the illustrated embodiment is only an example for carrying out the present invention, and various changes can be made to the feeder of the present invention without departing from the gist thereof.
