Description

  The present invention includes a common touch roller that can contact a winding roll of a plurality of divided sheets formed on a winding shaft, and a plurality of individual touch rollers that can individually contact the winding roll. The present invention relates to an individual touch roller support device that detachably supports an individual touch roller along a common touch roller.

  Conventionally, in the individual touch roller support device as described above, a support shaft supported near the common touch roller by a support arm that supports the common touch roller, one end is mounted on the end of the individual touch roller, and the other A swing arm having a hook portion formed in a hook shape at one end, and a cylindrical slide body for each swing arm, which is mounted on the outer peripheral surface of the support shaft so as to be positioned in the longitudinal direction of the support shaft. is there. An annular groove is formed on the outer peripheral surface of the slide body, and the individual touch roller is supported so that it can swing around the support shaft by hooking the hook-like hooking part of the swinging arm into the groove. Is done. The individual touch roller supported by the support shaft generates a pressing force against the divided sheet take-up roll by gravity acting on itself and the swing arm (see Patent Document 1 below).

  However, the winding conditions such as the material and thickness of the divided sheet to be wound in the sheet split winding device as described above, the width of the split sheet, and the like are diversified. Accordingly, it is required to adjust the contact pressure between the individual touch roller and the take-up roll to an appropriate size by making the pressing force of the take-up roll by the individual touch roller an optimum magnitude. Yes.

  However, since the touch roller support device described above cannot apply a rotational force other than the rotational force based on gravity to the swing arm of the individual touch roller, the magnitude of the pressing force of the individual touch roller to the winding roll is small. Regulation depends only on gravity. Therefore, in the above-described sheet split winding device, when the winding conditions are variously changed, it becomes impossible to apply the optimum contact pressure from the individual touch roller to the winding roll. Therefore, there is a problem that it is impossible to improve the quality of the winding roll corresponding to various winding conditions.

  Further, in the conventional sheet split winding device, in order to be able to change the pressing force of the take-up roll by the individual touch roller, a support shaft provided in parallel and rotatable with the individual touch roller, and a support shaft are provided. A fluid pressure cylinder device that applies the required rotational force, a support arm that swingably attaches to the support shaft, and supports the individual touch roller, and a rotation of the support shaft relative to the support arm provided between the support shaft and the support arm. Some have a spring device that resiliently resists force (see Patent Document 2 below).

  However, in this sheet split winding device, the support arms of the individual touch rollers are mounted in a state of penetrating the outer peripheral surfaces of both end portions of the movable member through which the support shafts supported at both ends by the machine frames on both sides penetrate. Therefore, unless the support shaft is removed from the machine frame, the individual touch roller cannot be replaced with one having a different length. Therefore, when the divided sheet width is changed, in order to use the individual touch roller having an appropriate length according to the width of the divided sheet, it is necessary to replace the individual touch roller which is troublesome and takes a long time. The above-described spring device includes a compression coil spring provided between a lateral member fixed to a pair of arm members and an arm member fixed to the movable member, and the compression coil springs are fixed to the pair of arm members. Since it is penetrated and held by the bolt attached to the horizontal member and the arm member fixed to the movable member, it is necessary to increase the distance between the support shaft and the touch roller, and a large occupied space is required. Therefore, the above-described spring device is employed when the installation space is limited and small, such as when the individual touch roller and the common touch roller are close to each other and the support shaft and the common touch roller are close to each other. Even if it can not be used, the operability when adjusting the displacement amount of the compression coil spring to set the magnitude of the pressing force of the individual touch roller, or when replacing the compression coil spring with a different spring constant Causes the problem of worsening.

The common touch roller 3 may selectively perform two types of operations of touch winding and clearance winding, or the common touch roller 3 may perform only one type of operation of touch winding or clearance winding. . In the case of touch winding, the common touch roller 3 separates from the winding shaft 2 according to the winding thickness of the winding roll R while pressing the winding roll R with a predetermined pressing force. The roller 3 is separated from the winding shaft 2 in a state where a predetermined gap is maintained between the outer peripheral surface of the roller 3 and the outer peripheral surface of the winding roll R.

  FIG. 2 is a front view of the individual touch roller support device according to the embodiment of the present invention, and FIG. 3 is a side view of the same. The individual touch roller support device 6 has a support shaft 9 supported at both ends by a pair of support arms 4 near the common touch roller 3, one end mounted on the end of the individual touch roller 5, and the other end in FIG. 3. As shown in the drawing, the support shaft has a swinging arm 10 provided for each individual touch roller 5 having a hooking portion 10a formed in a bowl shape, and a hooked portion 11a corresponding to the hooking portion 10a of the swinging arm.

The hooking portion 10 a has an inner peripheral surface that matches the outer peripheral surface 9 a of the support shaft 9. That is, the radius on the inner peripheral side of the hook-shaped hooking portion 10 a is the same as the radius of the support shaft 9. Therefore, the outer peripheral radius of the hooking portion 10a and the outer diameter of the cylinder 11 can be reduced, which is convenient for reducing the distance between the support shaft 9 and the individual touch roller 5 as much as possible.

  When the hooking portion 10a of the swing arm 10 is attached to the hooked portion 11a of the cylindrical body 11, the individual touch roller 5 is supported by the support shaft 9 so as to be swingable around it, and the common touch roller 3 is touched. In either case of winding or clearance winding, the winding roll R can be individually contacted during winding of the divided sheet S. Further, by removing the individual touch roller 5 from the support shaft 9, it is possible to perform touch winding or clearance winding using only the common touch roller 3.

  As shown in FIGS. 4 to 6, in the individual touch roller support device 6 of the present invention, in order to adjust the pressing force of the individual touch roller 5 to the winding roll, A rotating wheel 13 is rotatably mounted on the outer peripheral surface 11b of the portion adjacent to the portion 11a, and is a portion of the cylindrical body 11 adjacent to the portion on which the rotating wheel 13 is mounted, on the opposite side to the attached portion 11a. A rotating force setting wheel 14 is rotatably mounted on the outer peripheral surface 11c of the portion, and a coil spring 15 having one end connected to the rotating wheel 13 and the other end connected to the rotating force setting wheel 14 is connected to the rotating wheel 13 and the rotating force setting wheel. 14 is arranged along the outer periphery of the cylindrical body 11, the protrusion 16 is fixed on the outer peripheral surface of the rotating wheel 13, and the rotational force setting wheel 14 is fixed to the cylindrical body 11 by fixing the rotational force setting wheel 14. Means 17 is provided, and an engaging body 18 that can be engaged with the protrusion 16 is fixed to the side surface of the swing arm 10. That.

  In this embodiment, the fixing means 17 for fixing the rotational force setting wheel 14 to the cylindrical body 11 includes a set screw screwed to the rotational force setting wheel 14. Both sides of the hooked portion 11a of the cylindrical body 11 are hook-shaped on both sides with respect to the outer peripheral surface 11b. The rotating wheel 13 is loosely fitted to the outer peripheral surface 11b of the cylindrical body 11, and the rotational force setting wheel 14 Are fitted on the outer peripheral surface 11c of the cylindrical body 11, respectively. In order to restrain the rotational force setting wheel 14 from moving in the width direction when the set screw 17 is loosened, the fixed wheel 20 is loosely fitted to the outer peripheral surface of the end portion of the cylindrical body 11, and the fixed wheel 20 is stopped. It is fixed to the cylinder 11 with a screw 21.

  The coil spring 15 is a tension coil spring, and one end of the coil spring 15 projects toward the rotating wheel 13 and the other end projects toward the rotating force setting wheel 14 in order to connect the other end to the rotating wheel 13. The pin 22 (shown by a solid line in FIG. 5) is fastened, and the pin 23 (shown by a two-dot chain line in FIG. 5) is fastened to the rotational force setting wheel 14 so that the tip protrudes toward the rotating wheel 13. As shown in FIG. 6, one end of the coil spring 15 is hung on the pin 22 and the other end is hung on the pin 23.

  The cylindrical body 11 is fitted into the outer peripheral surface of the support shaft 9 and has a set screw 24 for fixing at a required position on the support shaft. A key groove 25 extending in the longitudinal direction is formed on the outer peripheral surface of the support shaft 9. The set screw 24 penetrates the fixed ring 20 and is screwed into the cylindrical body 11, and the distal end portion of the set screw 24 protruding from the inner peripheral surface of the cylindrical body 11 is fitted in the key groove 25. Therefore, after moving the cylinder 11 to a required position on the support shaft 9, the cylinder 11 can be positioned by tightening the set screw 24 and fixing the cylinder 11. At this time, the cylinder 11 cannot rotate with respect to the support shaft 9.

  As shown in FIG. 2, a scale 26 corresponding to the rotational force of the swing arm 10 is provided on the outer peripheral surface of the rotating wheel 13, and a pointer 27 for the scale 26 is provided on the outer peripheral surface of the rotational force setting wheel 14. is there. If necessary, the scale 26 may be provided on the outer peripheral surface of the rotational force setting wheel 14 and the pointer 27 may be provided on the outer peripheral surface of the rotating wheel 13.

  In the individual touch roller support device 6 configured as described above, in order to mount the individual touch roller 5 at a required position of the support shaft 9, a pair of swing arms when the individual touch roller 5 is disposed at the required position. The pair of cylinders 11 are positioned at positions corresponding to 10, and then the hooking portions 10 a of the swing arm 10 attached to both ends of the individual touch roller 5 are placed on the hooked portions 11 a of the cylinder 11. Hang on. At this time, as shown in FIG. 3, the engaging body 18 of the swing arm 10 is disposed on the front side of the protrusion 16 in the direction indicated by the arrow E. When the positional relationship between the protrusion 16 and the engaging member 18 is reversed, the rotating wheel 13 is rotated by hand in the direction opposite to the direction indicated by the arrow E in FIG. After that, the swing arm 10 is attached.

  When the hooking portion 10 a of the swing arm 10 of the individual touch roller 5 is hooked on the hooked portion 11 b of the cylinder 10, the swing arm 10 can swing around the support shaft 9, and the rotating wheel 13 rotates. The force is transmitted to the swing arm 10 through the protrusion 16 and the engagement body 18 and is applied to the individual touch roller 5 as a pressing force to the winding roll R.

  When the coil spring 15 expands and contracts, an expansion / contraction force is generated to return to the original state, and the rotation force of the coil spring 15 generates a rotation force on the rotating wheel 13. On the other hand, in FIG. 1, the support shaft 9 separates from the outer peripheral surface of the winding roll together with the common touch roller 3 according to the winding thickness of the winding roll R during winding of the divided sheet S. The rotation angle with respect to the cylinder 11 hardly changes, and therefore the rotation angle of the rotating wheel 13 with respect to the cylinder 11 hardly changes. Therefore, the rotational force applied to the rotating wheel 13 is set by the rotational force setting wheel. That is, in order to expand and contract the coil spring 15 in advance so that a necessary rotational force is generated in the rotating wheel 13, the rotational force setting wheel 14 is rotated with respect to the cylindrical body 11 by a required rotational angle, and the cylindrical body by the set screw 17. 11 is fixed. In FIG. 6, when the rotational force setting wheel 14 is rotated counterclockwise with respect to the cylindrical body 15, the coil spring extends and the rotational force applied to the pin 22 of the rotating wheel 13 increases.

  When the pressing force of the individual touch roller 5 against the take-up roll R is excessive or insufficient, the set screw 17 is loosened, and the cylindrical body of the rotational force setting wheel 14 so that an appropriate rotational force is applied to the rotational wheel 13. 11 is changed. When it is necessary to increase the pressing force of the individual touch roller 5 on the winding roll, the rotational force setting wheel 14 is rotated in the direction of arrow E in FIG. By fixing the rotational force setting wheel 14 to the cylinder 11 with a screw, it is possible to increase the extension of the coil spring 15 and apply a large rotational force to the rotating wheel 13. On the other hand, when it is necessary to reduce the pressing force of the individual touch roller 5 on the winding roll, the rotational force setting wheel 14 is moved in the direction opposite to the direction indicated by the arrow E in FIG. Rotate.

  If the rotational force required for the rotating wheel 13 cannot be obtained because the spring constant of the coil spring 15 is small, the coil spring 15 is replaced with one having a large spring constant. In order to replace the coil spring 15, in order to allow the coil spring 15 to be attached and detached, the set screw 24 is removed and the set screw 21 is loosened, and the fixed ring 20 is extracted from the cylinder 11 to the left in FIG. The rotational force setting wheel 14 is loosened and moved to the left in FIG. One end and the other end of the coil spring 15 are removed from the pin 22 and the pin 23, respectively. Instead, one end and the other end of the coil spring 15 having different spring constants are attached to the pin 22 and the pin 23, respectively. Thereafter, the rotational force setting wheel 14 and the fixed wheel 20 are returned to the normal positions shown in FIG. 5, the set screw 24 is attached to the cylindrical body 11 to fix the cylindrical body 11, and the rotational force setting wheel 14 is attached to the cylindrical body 11. On the other hand, it is rotated by a required angle and fixed with a set screw 21. The replacement of the coil spring 15 is simple because it can be performed without removing the cylindrical body 11 from the support shaft 3, and the replacement time is short.

  Embodiments of the present invention can vary widely as needed. For example, the cylinder 11 shown in FIG. 5 may be changed as shown in FIG. 8 includes a groove formed in the circumferential direction on the outer peripheral surface of the cylinder 11, and the width of the groove 11a matches the width of the hooking part 10a of the swing arm 10. The bottom surface of the groove 11 a is adapted to the inner peripheral surface of the hook-shaped hooking portion 10 a of the swing arm 10. Further, instead of the fixed wheel 20 shown in FIG. 5, a retaining ring 20 attached to a circumferential groove formed on the outer peripheral surface near the other end of the cylinder 11 is provided as a restraining means for the rotational force setting wheel 14. . Further, a fixing means (set screw) 24 for fixing the cylindrical body 11 to the support shaft 9 is disposed on the flange portion 11 d on one end side of the cylindrical body 11.
