Description

  The present invention relates to a slitter device that cuts a sheet-like material to be cut into a plurality of strip-shaped materials having a predetermined width, and more particularly to a slitter device that can easily adjust the clearance between an upper blade and a lower blade.
  In general, as shown in FIG. 7, the conventional slitter device includes a first and a second stand bodies 2 and 3 fixed on a base 1, and a plurality of them that are rotatably supported between them. The ring-shaped upper blade 4 and lower blade 5 are attached to a cylindrical upper shaft 6 and a lower shaft 7.
  Here, the first stand main body 2 is provided on a rail mount 8 provided on the base 1 so as to be movable in the axial direction.
  The first and second stand main bodies 2 and 3 are formed with two through holes 5 spaced in the vertical direction, and an upper shaft 6 and a lower shaft 7 are formed in the through holes 5. The bearings 9 are rotatably fixed to each other.
  The upper blades 4 adjacent to each other on the upper shaft 6 are adjusted to have an interval so as to cut the material to be cut with a predetermined width by interposing a ring-shaped spacer 10. A clearance adjusting spacer 50 for adjusting the clearance is disposed at the end on the second stand main body 3 side.
  Further, the adjacent lower blades 5 of the lower shaft 7 are also adjusted to the same interval as the upper blade 4 by interposing a spacer 11 having the same width as that used for the upper blade 4, and A clearance adjusting spacer 51 for adjusting the clearance is disposed at the end of the lower shaft 7 on the second stand main body 3 side.
  As shown in FIG. 9, the slitter device having the above configuration adjusts the horizontal clearance and the vertical lap of the upper blade 4 and the lower blade 5, and then rotates the upper shaft 6 and the lower shaft 7 around the axis. The material to be cut fed between the upper shaft 6 and the lower shaft 7 is cut by a shearing force.
  By the way, the conventional slitter device changes the distance between the upper blade 4 and the lower blade 5, that is, the width of the spacers 10 and 11 each time the width dimension of the belt-like material changes, so that the upper blade 4 and the lower blade 5 are attached. Therefore, it was necessary to adjust the horizontal clearance accordingly.
  In the conventional slitter device, the horizontal clearance adjustment method for the upper blade 4 and the lower blade 5 is as follows. First, the first stand main body 2 is moved by the rail mount 8 to move the upper stand 4 from the first stand main body 2. Remove the shaft 6 and the lower shaft 7.
  Then, the cutter clamping nut 12 attached to the other end of the upper shaft 6 shown in FIG. 8 and pressing the upper blade 4 is removed, and then the upper blade 4, the spacer 10, and the clearance adjusting spacer 50 are removed.
  Next, again, a plurality of upper blades 4 are disposed on the upper shaft 6, and a plurality of spacers 10 having a width corresponding to the cutting width of the material to be cut are disposed between the upper blades 4. The clearance adjustment spacer 50 is disposed on the blade assembly.
  After that, the cutter clamping nut 12 is attached to the other end portion of the upper shaft 6 and tightened to press the upper blade 4, the spacer 10, and the clearance adjusting spacer 50, and the upper blade 4, the spacer 10, and the clearance are pressed. The adjustment spacer 50 is fixed.
  Next, similarly, the cutter tightening nut 12 attached to the other end of the lower shaft 7 is removed, and then the lower blade 5, the spacer 11, and the clearance adjusting spacer 51 are removed.
  Then, again, a plurality of lower blades 5 are disposed on the lower shaft 7, and a plurality of spacers 11 having the same width as the spacer 10 used for the upper blade 4 are disposed between the lower blades 5. A clearance adjustment spacer 51 having a width narrower than that of the clearance adjustment spacer 50 is arranged on one end side of the clearance 7 to perform blade assembly. That is, the upper blade shown in FIG. 8B is obtained by shifting the arrangement of all the lower blades 5 by the clearance by the clearance adjustment spacer 51 of the lower shaft 7 in the direction of the other end by the clearance. The clearance between 4 and the lower blade 5 is adjusted.
  Next, the lower end blade 5, the spacer 11, and the clearance adjusting spacer 51 are pressed by attaching and tightening the cutter tightening nut 12 to the other end portion side of the lower shaft 7, thereby lowering the lower blade 5, the spacer 11, and the clearance. The adjustment spacer 51 is fixed.
  Thereafter, the first stand main body 2 is moved by the rail mount 8, the upper shaft 6 and the lower shaft 7 are attached from the first stand main body 2, and then the upper shaft 6 is moved up and down, whereby FIG. The vertical lap of the upper shaft 6 and the lower shaft 7 shown in FIG.
  However, in the conventional method for adjusting the horizontal clearance of the upper blade 4 and the lower blade 5, the upper blade 4, the lower blade 5, the spacers 10 and 11, and the clearance adjusting spacers 50 and 51 are heavy. In addition, replacement work is very difficult, workability is very poor, and preparation takes time.
  For this problem, without using spacers and clearance adjustment spacers, place a flat gauge between the cutting surfaces of the upper and lower blades after setting the upper and lower blades at a predetermined interval. A slitter device has been proposed that adjusts the clearance between the upper blade and the lower blade by removing the flat gauge after the upper blade and the lower blade are fixed to the upper shaft and the lower shaft.
  In this slitter device, the clearance between the upper and lower blades is adjusted by first adjusting the distance between the upper blades attached to the upper shaft to a predetermined width by using a caliper to cut the material to be cut into a predetermined width. The upper blade is fixed to the upper shaft by expanding the diameter of the upper shaft composed of the expansion / contraction shaft by hydraulic expansion / contraction.
  Then, the above flat gauge for adjusting the clearance is selected and pressed against the cutting surface of the upper blade fixed to the upper shaft, and further, the cutting surface of the lower blade attached to the lower shaft is pressed against the flat gauge. After the contact, the diameter of the lower shaft made up of the hydraulic expansion / contraction shaft is expanded by hydraulic expansion / contraction, thereby fixing the lower blade to the lower shaft and removing the flat gauge.
  However, the slitter device adjusts the distance between the upper blades 4 by positioning a plurality of conventional spacers 10 and 11 shown in FIG. 7 because the distance between the upper blades is adjusted using a caliper. This method has a problem that the gap between the upper blades tends to vary.
  In addition, the clearance between the upper and lower blades varies depending on how the flat gauge is applied to the cutting surfaces of the upper and lower blades, so there is also variation in the clearance between the upper and lower blades. There was a problem that it was likely to occur.
  The present invention has been made to solve the problems of the prior art, and provides a slitter device capable of adjusting the clearance between a plurality of upper blades and lower blades efficiently and accurately. It is.
  In order to solve the above-mentioned problem, the present invention according to claim 1 is provided on the outer periphery of the upper shaft and the lower shaft supported in parallel in the horizontal direction by bearings provided on a pair of stand bodies fixed on the base. Along each of the upper and lower blades having convex shapes, the horizontal and vertical laps of the upper and lower blades are adjusted, and the upper and lower shafts are rotated around the axis. In the slitter device for cutting the sheet-like material to be cut fed between the upper shaft and the lower shaft by a shearing force, the lower shaft is provided to be movable in the axial direction, and at one end of the lower shaft. An axial slide mechanism for moving the lower shaft in the axial direction is provided.
  According to a second aspect of the present invention, the axial slide mechanism includes a drive shaft that is fixed on the same axis as the lower shaft and has a male screw portion formed on the outer periphery, covers the drive shaft, A drive cylinder body that is provided with a female screw portion that meshes with the male screw portion formed on the outer periphery of the drive shaft and that is rotatable around the axis line while being prevented from moving in the axial direction. And a drive means for rotating the drive cylinder.
  Further, according to the third aspect of the present invention, a through hole that penetrates the lower shaft is formed in the stand main body on the one end side of the lower shaft, and the lower shaft has a through hole formed in the through hole. It is characterized by comprising a bearing cover that can move integrally with movement in the axial direction, and the bearing that is fixed to the bearing cover and rotatably supports the lower shaft. .
  According to the first to third aspects of the present invention, the lower shaft is provided so as to be movable in the axial direction, and an axial direction slide mechanism for moving the lower shaft in the axial direction is provided at one end of the lower shaft. Therefore, as the lower shaft moves in the axial direction, the plurality of lower blades fixed to the lower shaft also move in the axial direction at the same time. For this reason, once the upper blade is adjusted to an interval so as to cut the material to be cut into a predetermined width, and the lower blade is moved and brought into contact with the upper blade, The horizontal clearance of the plurality of upper and lower blades is adjusted simultaneously by adjusting the interval to cut to a predetermined width and then moving the lower shaft in the axial direction by the axial slide mechanism. Is possible. As a result, it is possible to adjust the horizontal clearances of the plurality of upper blades and lower blades efficiently and accurately.
  In particular, according to the second aspect of the present invention, the axial slide mechanism includes a female screw portion formed on the inner periphery of the drive cylinder while the drive shaft is fixed on the same axis as the lower shaft. The male screw portion formed on the outer periphery of the drive shaft meshes, and the drive shaft is moved in the axial direction by rotating the drive cylinder by the drive means. Accordingly, since the driving force that moves in the axial direction of the lower shaft acts on the axis of the lower shaft, the lower shaft can be moved in the axial direction with high accuracy.
  By the way, when only the lower shaft is moved in the axial direction by the axial slide mechanism, friction is generated at a contact portion between the bearing supporting the lower shaft and the lower shaft. That is, a load in the axial direction is applied to the contact portion between the lower shaft and the bearing. As a result, the contact portion between the lower shaft and the bearing gradually wears to create a gap between the lower shaft and the bearing, and the moving direction of the lower shaft deviates from the axial direction. There is a possibility that the cutting material cannot be cut to a predetermined width.
  According to the third aspect of the present invention, the stand main body on the one end side of the lower shaft is formed with a through hole that penetrates the lower shaft. A bearing cover that can move integrally with the movement of the lower shaft in the axial direction, and the bearing that is fixed to the bearing cover and rotatably supports the lower shaft. For each of the bearings fixed to the cover, the lower shaft can be moved in the axial direction. As a result, the load is not applied to the contact portion between the lower shaft and the bearing, so that the lower shaft moves reliably in the axial direction. As a result, the material to be cut can be reliably cut into a predetermined width.

The hydraulic cylinder 48 is moved.
  Next, the adjustment method of the horizontal clearance of the upper blade 32 and the lower blade 33 of the slitter apparatus of this embodiment is demonstrated.
  First, a plurality of blade holders 34 having the upper blade 32 of the upper shaft 13 are arranged in width dimensions corresponding to the cutting width of the material to be cut by the automatic positioning devices 38 provided at both ends of the upper shaft 13. .
  Next, by applying hydraulic pressure to the upper shaft 13 via the rotary joint 35 provided on the one end side of the upper shaft 13, the diameter of the upper shaft 13 is expanded and a plurality of blade holders 34 having the upper blades 32 are provided. , And fixed to the upper shaft 13 respectively.
Then, as shown in FIG. 6A, the vertical wraps of the upper blade 32 and the lower blade 33 are adjusted by the height adjusting mechanism 56 provided on the upper portions of the first and second stand bodies 18 and 24. To do.
  Next, as shown in FIG. 6 (b), the plurality of blade holders 34 having the lower blades 33 of the lower shaft 14 are brought into contact with the cutting surfaces of the lower blades 33 and the upper blades 32 of the upper shaft 13, respectively. Move to touching position.
  Then, by applying hydraulic pressure to the lower shaft 14 through the rotary joint 35 provided on the one end side of the lower shaft 14, the diameter of the lower shaft 14 is expanded by hydraulic expansion and contraction, and a plurality of blades having the lower blade 33. The holders 34 are fixed to the lower shaft 14 respectively.
    Next, the servomotor 41 of the axial slide mechanism 15 provided at one end of the lower shaft 14 is activated. Then, the driving force of the servo motor 41 is transmitted to the worm gear 46 via the timing belt 52, and the worm gear 46 rotates. As a result, the drive cylinder 40 rotates around the axis by the worm gear 45 of the drive cylinder 40 meshed with the worm gear 46, and the female screw portion 44 and the drive shaft 39 formed on the inner periphery of the drive cylinder 40. The drive shaft 39 is moved in the axial direction by the male screw portion 42 formed in FIG.
  Then, the driving force in the axial direction of the drive shaft 39 is transmitted to the joint case 36 via the contact plate 43 attached to the drive shaft 39. The driving force is further transmitted to the support plate 29 in contact with the joint case 36, and then transmitted to the axis cover 27 in contact with the support plate 29, whereby the axis cover 27 is The lower shaft 14 and the bearing 21 move in the axial direction.
  As a result, the lower shaft 14 is once moved forward to the first stand main body 18 side, then moved back to the second stand main body 24 side, the origin of the lower shaft 14 is determined, and this position is set to the upper blade. 32 and the lower blade 33 are set to the 0 position of the clearance.
  Next, the axial slide mechanism 15 provided at one end of the lower shaft 14 is activated again, the drive shaft 39 is moved in the axial direction, and the lower shaft 14 is moved backward toward the second stand body 24 side. Thus, when the clearance between the upper blade 32 and the lower blade 33 is adjusted to a predetermined clearance to cut the material to be cut into a predetermined width, the servo motor 41 is stopped.
  Thereafter, the drive shaft 39 is fixed by the fixed shaft 47 by applying hydraulic pressure to the hydraulic cylinder 48 of the lower shaft positioning mechanism 16.
  In the slitter device having the above configuration, the lower shaft 14 is provided so as to be movable in the axial direction, and an axial slide mechanism 15 for moving the lower shaft 14 in the axial direction is provided at one end of the lower shaft 14. In addition, as the lower shaft 14 moves in the axial direction, the plurality of lower blades 33 fixed to the lower shaft 14 also move in the axial direction at the same time. For this reason, once the upper blade 32 is adjusted to an interval so as to cut the material to be cut into a predetermined width, and the lower blade 33 is moved and brought into contact with the upper blade 32, the lower blade 33 is covered. By adjusting the interval to cut the cutting material to a predetermined width, and then moving the lower shaft 14 in the axial direction by the axial slide mechanism 15, the horizontal clearance between the plurality of upper blades 32 and the lower blades 33 is reduced. It becomes possible to adjust all at once. As a result, it is possible to adjust the horizontal clearance of the plurality of upper blades 32 and lower blades 33 efficiently and accurately.
  The axial slide mechanism 15 includes a drive shaft 39 fixed on the same axis as the lower shaft 14, a female screw portion 44 formed on the inner periphery of the drive cylinder 40, and an outer periphery of the drive shaft 39. The formed male screw portion 42 meshes, and the drive cylinder 39 is moved in the axial direction by rotating the drive cylinder 40 by the servo motor 41. Thereby, since the driving force that moves in the axial direction of the lower shaft 14 acts on the axis of the lower shaft 14, the lower shaft 14 can be moved in the axial direction with high accuracy.
  Further, the second stand main body 24 is formed with a through hole 20 that allows the lower shaft 14 to pass therethrough, and can move integrally in the through hole 20 as the lower shaft 14 moves in the axial direction. Since the bearing cover 27 and the bearing 21 fixed to the bearing cover 27 and rotatably supporting the lower shaft 14 are provided, the lower shaft 14 and the bearing 21 fixed to the bearing cover 27 are combined. It is possible to move in the axial direction. As a result, no load is applied to the contact portion between the lower shaft 14 and the bearing 21, so that the lower shaft 14 moves reliably in the axial direction. As a result, the material to be cut can be reliably cut into a predetermined width.
  Further, in the previous stage of adjusting the clearance between the upper blade 32 and the lower blade 33, the second shaft main body 24 side is moved to the first stand main body 18 side after advancement toward the first stand main body 18 side in order to find the origin of the lower shaft 14. By moving backward, the rattling between the female screw portion 44 formed on the inner periphery of the drive cylinder 40 and the male screw portion 42 formed on the outer periphery of the drive shaft 39 can be prevented. It becomes.
  Since the lower shaft 14 is retracted toward the second stand body 24 and the clearance between the upper blade 32 and the lower blade 33 is adjusted, the drive shaft 39 is fixed by the lower shaft positioning mechanism 16, so that the cutting is performed. Shaking of the lower shaft 14 in the axial direction that occurs at times can be prevented. Thereby, the lower shaft 14. Since it is difficult for a load to be applied to the bearing 21 and the bearing cover 27, durability can be improved.
