Description

  The present invention relates to a roll winding auxiliary device that can be mounted on a winding device that winds a sheet material to manufacture a roll product and realizes stable production of the roll product.

  FIG. 6 shows a known multi-axis turret type winding device 30. The winding device 30 winds the sheet material 5 supplied from the left side in the drawing around one winding shaft 4 (left side in the drawing) that is rotationally driven, and the sheet material 5 wound around the one winding shaft 4 is a predetermined one. Assuming that the length has been reached, the turret 3 is swung while the sheet material 5 continues to be wound around the one winding shaft 4, so that the position of the one winding shaft 4 and the other winding shaft 4 can be mutually adjusted. replace. That is, one winding shaft 4 moves to the right in the drawing, and the other winding shaft 4 moves to the left in the drawing.

  In this state, the sheet material 5 extends from the other winding shaft 4 (left in the figure) toward one winding shaft 4 (right in the drawing). This extended portion is cut by a cutter 21 disposed below the other winding shaft 4. At the same time, the vicinity of the cut edge of the sheet material 5 is pressed against the other winding shaft 4 that is rotationally driven by the touch roller 22, so that the sheet material 5 starts to be wound around the other winding shaft 4 as it is. By repeating the above operation, the sheet material 5 is alternately wound around the two winding shafts 4. Further, the sheet material 5 wound around the two winding shafts 4 is detached from the winding shaft 4 and becomes a roll product. Techniques relating to the multi-axis turret type winding device are disclosed in the following patent documents.

Japanese Patent Laid-Open No. 11-106098

  However, the winding device 30 described above immediately after the sheet material 5 extending from the other winding shaft 4 (right in the drawing) toward the one winding shaft 4 (left in the drawing) is cut by the cutter 21. However, as indicated by reference numeral 51 in the figure, the roll-shaped sheet material 5 wound around one winding shaft 4 may hang downward. There is a problem that the sheet material 51 that hangs down is damaged by rubbing against the base plate 23 of the apparatus 20 or is slightly soiled by dust or the like that has accumulated on the base plate 23. Further, immediately before the roll-shaped sheet material 5 is removed from the one winding shaft 4, the one winding shaft 4 is disconnected from a driving source for rotationally driving it, and can be freely rotated. For this reason, the one winding shaft 4 is inadvertently reversed in the direction opposite to the winding direction, the roll-shaped sheet material 5 is unwound, and the above problem occurs.

  An object of the present invention is to provide a roll winding assist device that can prevent damage or contamination of a sheet material.

  The present invention supports a plurality of winding shafts in a horizontal posture on a turret that can turn around a horizontal axis, and turns the turret while winding a sheet material around one winding shaft of the plurality of winding shafts. Thus, the one winding shaft and another winding shaft positioned horizontally apart from the one winding shaft are replaced with each other, and the sheet material is allowed to pass in the vicinity of the other winding shaft and A roll winding auxiliary device attached to a multi-axis turret type winding device that cuts the sheet material in the vicinity of the other winding shaft in the process of winding on one winding shaft, Roller contact is possible between a guide roller that is provided between the other winding shaft and receives the sheet material wound around the one winding shaft, and a body portion of the sheet material wound around the one winding shaft. The touch roller, the guide roller and the touch roller Characterized in that it comprises an elevating support means for raising and lowering a plurality of in and out of the trajectory of the winding shaft that moves with the pivot of Tsu and.

  Furthermore, the roll winding assist device according to the present invention is characterized in that the touch roller is provided with a reverse rotation preventing means for allowing only the rotation in the forward rotation direction in which the touch roller is in rolling contact with the body portion. Further, the guide roller may be provided with a reverse rotation preventing means that allows only rotation in the same direction as the forward rotation direction.

  Furthermore, in the roll winding assist device according to the present invention, the touch roller or the guide roller includes a support shaft, the elevating support means includes a bracket for supporting the support shaft, and the reverse rotation prevention means includes the support shaft. A claw wheel connected to a shaft to form a plurality of check pawls, and when the claw wheel rotates in the forward rotation direction, the claw wheel is detached from the check pawls and reverses in a direction in which the claw wheel reverses in the forward rotation direction. And a latching piece for latching the non-return claw.

  Further, in the roll winding assist device according to the present invention, the elevating support means includes a first support body having a base end that is pin-bonded below the turret and a front end that is pivotable around the base end, A second support body having a posture in which one end is pin-bonded to the front end of one support body and the other end extends in a horizontal direction; and the front end of the first support body is swung by rotating the first support body. A drive source that moves up and down, and a four-bar crank mechanism that interlocks with the first support and maintains the posture of the second support, and supports the guide roller at one end of the second support, The touch roller is supported on the other end of the second support.

  According to the roll winding assist device of the present invention, one winding shaft that continues to wind up the sheet material by turning the turret while winding the sheet material on one winding shaft of the plurality of winding shafts, and Since the other winding shaft that is separated from the one winding shaft in the horizontal direction and stands by can be replaced, the sheet material passes through the vicinity of the other winding shaft and is wound around the one winding shaft. On the other hand, in the process of turning the turret, the elevating support means can lower the guide roller and the touch roller so that the guide roller and the touch roller do not block the trajectories of the plurality of winding shafts that move with the turret. . Then, as described above, in the process in which the sheet material passes through the vicinity of the other winding shaft and is wound on one winding shaft, the lifting support means raises the guide roller and the touch roller. Thus, immediately after the sheet material is cut in the vicinity of another winding shaft, the sheet material is received by the guide roller and the touch roller.

  Accordingly, since the sheet material does not hang down below one winding shaft, the sheet material is not rubbed and damaged by the base plate of the winding device, and dust or the like does not adhere to the sheet material. In addition, the touch roller is in rolling contact with the body of the sheet material wound around one winding shaft, so that it does not prevent the one winding shaft from still rotating after the sheet material is cut. In addition, it is possible to prevent the portion near the cut edge of the sheet material cut as described above from being peeled off or warped immediately after being wound around one winding shaft.

  Further, according to the roll winding assist device according to the present invention, the forward rotation direction when the touch roller is in rolling contact with the body portion of the sheet material wound around one winding shaft is defined by the reverse rotation preventing means, The touch roller can be rotated only in the forward direction. For this reason, immediately before the sheet material wound in a roll shape is removed from the one winding shaft, the one winding shaft is cut from a drive source or the like that rotationally drives it, and can be freely rotated. Even if the shaft is inadvertently reversed in the direction opposite to its winding direction, this can be prevented by the reverse rotation preventing means. Therefore, it is possible to reliably prevent the conventional problem from being induced by unraveling of the sheet material already wound in a roll shape on one winding shaft or unraveling of the sheet material.

  Further, the roll winding assist device according to the present invention is provided with the reverse rotation preventing means for allowing only the rotation in the same direction as the normal rotation direction to the guide roller, so that the sheet cut near the other winding shaft It is possible to prevent a situation in which the vicinity of the cut end of the material is reversed toward the other winding axis due to the reverse rotation of the one winding axis as described above immediately before being wound on the one winding axis. Therefore, if the reverse rotation preventing means is provided for both the guide roller and the touch roller, the problem that the sheet material already wound in a roll shape can be surely prevented.

  Further, the reverse rotation preventing means applied to the roll winding assist device according to the present invention includes a claw wheel connected to the support shaft and formed with a plurality of check claws, and a check claw when the claw wheel rotates in the forward rotation direction. This is a so-called ratchet mechanism provided with a latching piece for latching the check pawl when the claw wheel is reversely moved in the direction reverse to the normal rotation direction. For this reason, in addition to the structure of the reverse rotation preventing means being extremely simple and reliable, the manufacturing cost of the reverse rotation preventing means is extremely low. Therefore, while achieving a remarkable effect by preventing the reverse rotation, the reliability of the apparatus is improved, the maintenance is simplified, and the manufacturing cost is reduced.

  Further, the lifting support means applied to the roll winding assist device according to the present invention is such that the base end of the first support is pin-joined below the turret, and the second support is at the tip of the first support. Even if one end of the first support is pin-joined and the first support is swung around its base end by a driving source, the second support is linked to the first support by a chain of four-bar crank mechanisms. Retained by the action of Therefore, the guide roller supported on one end of the second support that moves up and down (up and down) as the first support rotates and the touch roller supported on the other end of the support are horizontal. It is possible to move up and down with almost no change in the direction interval. For this reason, even if the diameter of the body portion of the sheet material wound around one winding shaft changes and the height at which the touch roller rolls into contact with the body portion changes, the horizontal direction between the guide roller and the touch roller changes. Since the interval is substantially constant, the above-described effects of the guide roller and the touch roller can be stably achieved regardless of the diameter of the body of the touch roller.

  The roll winding assist device according to the present embodiment will be described. Constituent elements already described as well-known techniques will be denoted by the same reference numerals and detailed description thereof will be omitted.

  FIG. 1 shows an example in which the roll winding auxiliary device 1 is attached to a multi-axis turret type winding device 30. The winding device 30 supports a plurality of winding shafts 4 in a horizontal posture on a turret 3 that can be swiveled around a horizontal shaft 2, and is mounted on one winding shaft 4 (left in the drawing) of the plurality of winding shafts 4. By turning the turret 3 while winding the sheet material 5, one winding shaft 4 and another winding shaft 4 (right side in the figure) positioned away from the one winding shaft 4 in the horizontal direction are placed. Are mutually replaced. In the state replaced in this way, the winding device 30 passes the vicinity of the other winding shaft 4 (left in the drawing) and winds the sheet material 5 on one winding shaft 4 (right in the drawing). In this process, the sheet material 5 is cut by the cutter 21 in the vicinity of the other winding shaft 4 at the timing when one winding shaft becomes full.

  The roll winding auxiliary device 1 includes a guide roller 6 that is provided between one winding shaft 4 and another winding shaft 4 and receives a sheet material 5 that is wound on one winding shaft 4, and rolls on one winding shaft 4. Touch roller 7 that rolls into contact with the body portion 50 of the sheet material 5 wound in a shape, and the inside and outside of the circular orbit 40 of the plurality of winding shafts 4 that move the guide roller 6 and the touch roller 7 as the turret 3 turns. And elevating support means 8 for elevating and lowering.

  Furthermore, the roll winding assist device 1 allows only the rotation in the forward rotation direction in which the touch roller 7 is in rolling contact with the body portion 50, and prevents reverse rotation, which is the rotation in the reverse direction, as shown in FIG. It is desirable to provide the reverse reversal prevention means 9. It is desirable that the same reverse rotation preventing means 9 is provided on the guide roller 6 so that the guide roller 6 only allows rotation in the same direction as the normal rotation direction. First, an example of the reverse rotation prevention means 9 will be described below.

  That is, FIG. 2 shows that the touch roller 7 includes the support shaft 10 as a pivot, while the below-described lifting support means 8 includes a bracket 11 for supporting the support shaft 10 while bearing it. The reverse rotation prevention means 9 includes a claw wheel 13 that is connected to the support shaft 10 and has a plurality of check pawls 12, and a latch piece 14 that is a small piece that is pin-joined to the bracket 11. The latching piece 14 is detached from the non-return pawl 12 when the ratchet wheel 13 rotates in the forward rotation direction indicated by the arrow C in the figure, and reverse when the hook wheel 13 reverses in the direction reverse to the forward rotation direction. The pawl 12 is hooked. The advantages of the so-called ratchet mechanism as described above are that the structure is extremely simple and the operation is reliable, and the manufacturing cost is extremely low. Further, it is desirable that a material having a relatively large friction coefficient such as rubber is attached to the tread surface of the touch roller 7 as the anti-slip 70. The guide roller 6 is essentially the same as the touch roller 7 except for the position where the guide roller 6 is attached to the elevating support means 8, and the description thereof is omitted.

  Next, as shown in FIGS. 1, 3 (a), and 3 (b), the lifting support means 8 is joined to the base plate 23 below the turret 3 via the pin P and the distal end 16 is joined to the proximal end. A first support member 17 that can pivot around the first support member 17, and a second support member 17 that is joined to the tip end 16 of the first support member 17 via a pin P <b> 1 and the other end 19 extends substantially horizontally. And a four-bar crank mechanism 22 that interlocks with the first support 17 and maintains the posture of the second support 20 according to the principle described later. Further, although not shown in the drawings, the lifting support means 8 includes a drive source that turns the first support 17 and moves the tip 16 of the first support 17 up and down (lifts). Since the four-bar crank mechanism 22 is housed in the first support 17 and does not appear as an external appearance, only this operating principle is separately shown in FIG.

  The four-bar crank mechanism 22 has a pair of parallel nodes extending along the first support 17 through the slide P2 at both ends of the fixed node 220 housed in the base end 15 of the first support 17, respectively. The lower end of 221 is connected, and both ends of the movable node 222 are connected to the upper ends of the pair of parallel nodes 221 via the sliding nodes P3. The movable node 222 maintains a posture parallel to the fixed node 220 regardless of the turning angle of the pair of parallel nodes 221. Therefore, if the second support 20 is fixed to the fixed node 220 in a desired posture, for example, a substantially horizontal posture with the other end 19 slightly lowered as shown in the figure, the turning angle of the first support 17 Regardless, the posture of the second support 20 can be maintained.

  The second support 20 supports the guide roller 6 at one end 18 through the bracket 11 described above, and supports the touch roller 7 at the other end 19 through the bracket 11. The bracket 11 does not need to be a component attached to the second support 20, and as shown in the figure, the support shaft 10 is directly supported by the second support 20, and the second support 20 itself is the bracket. You may take a role. In this case, the pin P1 may be shared as the support shaft of the guide roller 6.

  The same lift support means 8 as described above are arranged so as to overlap in the figure, and the pair of lift support means 8 are in agreement with each other and operate as follows. That is, in the process of turning the turret 3, the elevating support means 8 includes the guide rollers 6 and 6 so that the guide rollers 6 and the touch rollers 7 do not block the circular orbits 40 of the plurality of winding shafts 4 that move with the turret 3. The touch roller 7 can be lowered. In this lowering process, the guide roller 6 supported by one end 18 of the second support 20 that moves up and down (up and down) as the first support 17 turns, and the other end of the second support 20 The touch roller 7 supported by 19 can be moved up and down without changing the horizontal distance between them. Therefore, even if the diameter of the body portion 50 of the sheet material 5 wound around one winding shaft 4 changes and the height at which the touch roller 7 rolls into contact with the body portion 50 changes, the guide roller 6 and the touch roller The horizontal distance from 7 is constant.

  Further, when the sheet material 5 passes through the vicinity of the other winding shaft 4 and is wound around the one winding shaft 4 as described above, the lifting support means 8 raises the guide roller 6 and the touch roller 7. The sheet material 5 is received by the guide roller 6 and the touch roller 7 immediately after the sheet material 5 is cut in the vicinity of the other winding shaft 4. Accordingly, since the sheet material 5 does not hang down below one winding shaft 4, the sheet material 5 may be damaged by rubbing against the base plate 23 of the winding device 30, or dust or the like may adhere to the sheet material 5. Absent. Moreover, since the touch roller 7 is in rolling contact with the body portion 50 of the sheet material 5 wound around the one winding shaft 4, the one winding shaft 4 is still driven to rotate after the sheet material 5 is cut. It will not prevent you. In addition, the touch roller 7 presses a portion near the cut edge of the sheet material 5 cut as described above, and this portion is peeled off from the body portion 50 immediately after being wound around the one winding shaft 4. Or warping back.

  Furthermore, according to the roll winding assist device 1, since the reverse rotation preventing means 9 can prevent the touch roller 7 from rotating reversely as described above, the sheet material 5 wound in a roll shape is removed from the single winding shaft 4. Immediately before, the one winding shaft 4 is cut off from a drive source or the like that rotationally drives it so that it can freely rotate. However, the one winding shaft 4 tries to inadvertently reverse in the direction opposite to its winding direction. However, this can be prevented by the reverse rotation preventing means 9. Therefore, it is possible to surely prevent the conventional problem from being caused by the unraveling of the sheet material 5 already wound in a roll shape on one winding shaft 4 and the unraveling of the sheet material 5. Moreover, in the case where the guide roller 6 is provided with the reverse rotation preventing means 9, the above-described vicinity of the cut end of the sheet material 5 cut in the vicinity of the other winding shaft 4 is immediately before the winding shaft 4 is wound up. It is possible to prevent a situation in which a reverse movement toward the other winding shaft 4 due to the reverse rotation of the one winding shaft 4 occurs.

  It should be noted that the present invention can be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, a brake device that loosely brakes the guide roller 6 or the touch roller 7 may be used as the reverse rotation preventing means 9.

  Further, instead of the lifting support means 8, a lifting support means 80 as shown in FIG. 4 may be applied. The lifting support means 80 is a pantograph mechanism in which a pair of parallel nodes 81 and 82 are joined to each other via pins P4 and P5. Although not shown, the pin P5 that connects the parallel node 81 and the parallel node 82 is formed with a female screw that penetrates these pins in the horizontal direction, and one feed screw is screwed to each female screw. Yes. When the feed screw is rotated by a driving source such as a motor, the pins P5 are moved closer to or away from each other, and the touch roller 7 supported on the upper ends of the pair of parallel nodes 82 is moved up and down. Similarly, the guide roller 6 may be moved up and down.

  Alternatively, instead of the lifting support means 8, a lifting support means 83 as shown in FIG. 5 may be applied. The lifting support means 83 is installed with a pneumatic or hydraulic cylinder 84 standing upright on the base plate 23 below the turret 3, and supports the touch roller 7 via the bracket 11 on the upper end of the operating rod 85 protruding from the upper end of the cylinder 84. It is a thing. When air pressure or hydraulic pressure is supplied to the cylinder 84, the operating rod 85 moves back and forth in the vertical direction, and the touch roller 7 moves up and down accordingly. Similarly, the guide roller 6 may be moved up and down.

  In the present invention, a roll product obtained by winding a sheet material into a roll with a winding device is removed from the winding device and carried out to other places. Or problems such as fouling can be prevented. Therefore, the occurrence of defects due to the above problems can be eradicated at the manufacturing site.
