On the other hand, there is one provided with attaching / detaching means for attaching / detaching the counter cylinder (for example, see Patent Document 1). In addition, there is a type in which the processing cylinder is supported by two eccentric bearings of an inner eccentric bearing and an outer eccentric bearing, and the eccentricity of the processing cylinder is attached and detached and the printing pressure is adjusted by rotating each of the eccentric bearings. (For example, refer to Patent Document 2).
JP 2003-291303 (paragraphs [0029] to [0031], FIG. 1) Japanese Utility Model Publication No. 54-118201 (2 pages 17 lines to 3 pages 9 lines, Fig. 2)

Among the conventional processing apparatuses described above, the former apparatus is not provided with means for adjusting the distance between the processing cylinder and the counter cylinder, so that it is not possible to adjust the pressing force of the processing plate on the material to be processed. There was a problem. In the latter apparatus, since the processing cylinder is supported by a so-called double eccentric bearing that supports the two eccentric bearings, the frame, one eccentric bearing, one eccentric bearing, the other eccentric bearing, and the other eccentric Since there is a clearance required for rotation or rotation between the bearing and the end shaft, the amount of free movement of the processing cylinder with respect to the frame increases. Therefore, when the processing cylinder is provided above the counter cylinder, when the processing cylinder is lifted within the clearance range against the dead weight by the sheet-like material passing between the processing cylinder and the counter cylinder, Since the amount of movement increases, there is a problem in that the accuracy of the pressing force applied to the sheet-like material by the processing cylinder is lowered and processing failure occurs.

The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a processing apparatus that improves the accuracy of the pressing force of the processing cylinder against the material to be processed and prevents processing defects caused by the processing cylinder. There is a place to do.

  In order to achieve this object, the invention according to claim 1 comprises a processing cylinder for processing a sheet-like material facing the counter cylinder, and an attaching / detaching means for attaching / detaching the processing cylinder to / from the counter cylinder. The processing apparatus includes an adjusting means for moving and adjusting the counter cylinder disposed above or below the processing cylinder in a perspective direction with respect to the processing cylinder, and the counter cylinder holds the sheet-like material. It has a nail.

The invention according to claim 2 is the invention according to claim 1, wherein the adjusting means includes a pair of eccentric eccentric bearings for supporting both ends of the counter cylinder, and the attaching / detaching means supports both ends of the processing cylinder. And a pair of detachable eccentric bearings.

The invention according to claim 3 is the invention according to claim 2, characterized in that the adjusting means includes drive transmission means for transmitting the drive of the motor to the pair of eccentric bearings for adjustment.

The invention according to a fourth aspect is the invention according to the third aspect, wherein the adjusting means is connected to each of a connecting shaft that is drivingly connected to the motor and a pair of the eccentric bearings for adjustment, and each of the adjusting shafts is connected to the connecting shaft. And a connecting means for driving and connecting.

According to a fifth aspect of the present invention, in the first aspect of the invention, the adjusting unit includes a motor that moves the counter cylinder in a perspective direction with respect to the processing cylinder, and sets the motor as an input value of the adjustment amount input unit. And a control device that performs control based on the control device.

  According to the present invention, the processing cylinder is attached to and detached from the counter cylinder, and the counter cylinder is moved in the perspective direction with respect to the processing cylinder in order to adjust the pressing force by the processing cylinder. The clearance between the bearing and the end shaft is divided between the processing cylinder and the counter cylinder. Therefore, when the sheet-like object passes between the counter cylinder and the process cylinder arranged above or below the process cylinder, the counter cylinder having the gripping claw for holding the sheet-like object and the process cylinder above The cylinder located is moved upward within a clearance range provided between the frame and the bearing and between the bearing and the end shaft. This is because there is room for upward movement because the upper body side clearance is located above due to its own weight, but the lower body side clearance is due to its own weight. Even if the sheet-like material passes between the two cylinders, the lower cylinder is pressed downward without clearance. There is no play. For this reason, a frame, one eccentric bearing, and one eccentric bearing in a so-called double eccentric support structure in which a cylinder positioned above is supported by an eccentric bearing for attachment and detachment and an eccentric bearing for adjusting the push-in amount as in the prior art. Compared to the other eccentric bearing and the clearance between the other eccentric bearing and the end shaft, the clearance on the upper cylinder side in the present invention can be reduced, and as a result, the sheet-like material is processed. The amount of movement of the upper cylinder can be minimized. Therefore, it is possible to prevent processing defects caused by the processing cylinder with respect to the sheet-like material and improve processing accuracy.

According to the third aspect of the present invention, it is not necessary to individually adjust the operation amounts of the pair of eccentric eccentric bearings by using a single motor as the driving source for the adjusting means, and therefore the adjustment work is facilitated. Adjustment accuracy is improved.

According to the fifth aspect of the present invention, it is possible to automatically adjust the pressing force by the processing cylinder on the material to be processed automatically only by inputting the input value to the adjustment amount input means.

The connecting means 139B described above includes a worm 156B, a worm wheel 155B, a rotating cylinder 154B, a drive shaft 157B, a rod 158B, and a lever 131B. As shown in FIG. 11, a worm 156A is pivotally attached to the end of the connecting shaft 138 protruding from the frame 86A.

Rotate clockwise. By this rotation, the drive shaft 157 in which the screw portion 157a is screwed into the screw hole 154b of the rotary cylinder 154B.
Since B moves in the direction of arrow C in FIG. 10, the rod 158B also moves in the direction of arrow C.

Since the rotation of the connecting shaft 138 rotates the worm 156A on the frame 86A side, the rotating cylinder 154B rotates in the clockwise direction in FIG. 11 via the worm wheel 155A engaged therewith. Therefore, the rod 158A on the frame 86A side moves in the direction of arrow C through the drive shaft 157A by the same distance as the rod 158B on the frame 86B side.

By moving these rods 158A, 158B in the direction of arrow C, levers 131A, 13

As a result, the counter cylinder 27 moves away from the processing cylinder 26.

On the other hand, when the adjustment motor 136 is driven in the reverse direction and the connecting shaft 138 is rotated via the gear 142 and the gear 144, the rotating cylinder 154B is rotated counterclockwise in FIG. 11 via the worm 156B and the worm wheel 155B.

Since the drive shaft 157B in which the screw portion 157a is screwed into the screw hole 154b of 54B moves in the arrow B direction in FIG. 10, the rod 158B also moves in the arrow B direction.

Since the rotation of the connecting shaft 138 rotates the worm 156A on the frame 86A side, the rotating cylinder 154B rotates counterclockwise in FIG. 11 via the worm wheel 155A engaged therewith. Therefore, the rod 158A on the frame 86A side moves in the direction of arrow B through the drive shaft 157A by the same distance as the rod 158B on the frame 86B side.

By moving these rods 158A, 158B in the direction of arrow B, the levers 131A, 13

6 is activated.

Reference numeral 168 denotes a gap amount input means as an adjustment amount input means. As shown in FIG. The gap amount t with the mounted plate 38 is input. This gap amount t is an amount obtained by subtracting the thickness of the paper 2 from the pressing amount of the pressing blade 172a with respect to the paper 2, that is, the thickness remaining without being cut by the pressing blade 172a. When a positive number of gaps is input to the gap input unit 168, the value is a thickness that is not cut by the pressing blade 172a. When a negative number of gaps is input to the gap input unit 168, the pressing blade 172a It penetrates the paper 2 and bites into the plate 38 attached to the counter cylinder 27.

This gap amount input means 168 can also be referred to as a pressing amount input means because it adjusts the pressing amount of the pressing blade 172a by inputting a thickness that is not pressed by the pressing blade 172a. Reference numeral 169 denotes adjustment amount input means for inputting the height T of the pressing blade 172a of the pressing blade plate 172 mounted on the processing cylinder 26, and is blade height input means as reference value input means. Here, the height T of the pressing blade 172a is the distance from the back surface of the pressing blade plate 172 to the tip of the pressing blade 172a, that is, the distance from the outer peripheral surface of the processing cylinder 26 to which the pressing blade plate 172 is mounted to the tip of the pressing blade 172a. It is. Reference numeral 170 denotes a control device that controls the adjustment motor 136 based on the adjustment amount input to the gap input means 168, the reference value input to the blade height input means 169, and the detection result of the counter barrel potentiometer 151. .

Next, in the processing apparatus configured as described above, the plate 3 is placed on the outer peripheral surface of the counter cylinder 27.
The operation of mounting 8 will be described. Air cylinders 88A, 88 for attaching / detaching the pressure roller in advance
By deactivating B, the pressing roller 87 is positioned at the retracted position separated from the outer peripheral surface of the counter cylinder 27. By rotating the operation portion 57a of the plate fixing shaft 57 and engaging the engaging surface 63a of the engaging body 63 with the stopper surface 61b of the bracket 60, the non-pressing portion 57d of the plate fixing shaft 57 is moved to the claw base. It is made to oppose the recessed part 45b of the bar 45. FIG. In this state, the insertion groove 46 between the claw base bar 45 and the wall surface 35a of the notch 35 is formed in FIG.
As shown in FIG. 4, the holding side end portion 38a of the plate 38 is inserted.

Next, the operation portion 57a of the plate fixing shaft 57 is rotated by a hexagon wrench with a hole or the like, and the engagement surface 63a of the engagement body 63 is engaged with the stopper surface 61a of the bracket 60 as shown in FIG. 4A, the pressing portion 57c of the plate fixing shaft 57 is opposed to the concave portion 45b of the claw base bar 45 as shown in FIG. Accordingly, the holding side end portion 38a of the plate 38 is formed into a concave portion 45b by the elastic force of the disc spring 66 as shown in FIG.
And the pressing portion 57c.

Thus, by providing the stopper surface 61a with which the engaging surface 63a of the engaging body 63 is engaged, the plate fixing shaft is held at a position where the holding side end portion 38a of the plate 38 is sandwiched between the recessed portion 45b and the pressing portion 57c. Since the rotation of 57 stops, the grip side end portion 38a is formed in the recess 4
It can be reliably supported by the 5b and the pressing portion 57c, and the operability is improved.
Further, the opposite sides of the neck portion 57e of the plate fixing shaft 57 are clamped by the tip portions 58a and 58a of the spring 58, so that the plate fixing shaft 5 is fixed.
7 can be held at the predetermined rotation position, so that the holding-side end 38a can be reliably supported by the recess 45b and the pressing portion 57c.

Next, the air cylinders 88A and 88B for attaching / detaching the pressure roller are operated, and the rods 89a and 8a are operated.
By retreating 9 a, the outer peripheral surface of the pressing roller 87 is positioned at the pressing position facing the outer peripheral surface of the counter barrel 27. In this state, the counter cylinder 27 is rotated counterclockwise in FIG. 2, so that the plate 38 is moved from the holding side end 38 a side of the plate 38 to the counter cylinder 2.
7 is attached to the outer peripheral surface. At this time, since the pressing roller 87 is positioned at the pressing position, the plate 38 is mounted while being pressed against the outer peripheral surface of the counter barrel 27 by the pressing roller 87. For this reason, the plate 38 is mounted in a state in which the plate 38 is in close contact without being lifted from the outer peripheral surface of the counter cylinder 27.

When the butt end 38b of the plate 38 is positioned on the butt end plate support means 40, the counter cylinder 27 stops rotating. In this state, the butt end 38b is inserted between the attachment surface 70a of the winding shaft 70 and the presser bar 72 as shown in FIG.
As a result, the bottom end 38b is sandwiched and supported between the presser bar 72 and the mounting surface 70a.

Next, the operating portion 77a of the operating shaft 77 is rotated with a hexagon socket wrench or the like, and the worm wheel 81 is rotated counterclockwise in FIG. 4 Turn clockwise. By this rotation, the plate 38
Since the bottom end portion 38b of the counter is wound around the winding shaft 70, the plate 38 is pulled in the circumferential direction of the counter cylinder 27 and attached to the outer peripheral surface of the counter cylinder 27.

Before the winding operation of the winding shaft 70, the entire plate 38 is already in close contact with the outer peripheral surface of the counter cylinder 27 by the pressing roller 87, so that the entire plate 38 is not lifted from the outer peripheral surface of the counter cylinder 27. Mounted in close contact. In particular, the angle of the bent portion of the holding side end portion 38 a matches the angle formed by the wall surface 35 a of the counter cylinder 27 and the effective surface, and the vicinity of the bent portion is in close contact with the effective surface of the counter cylinder 27. For this reason, since the holding side end portion 38a does not partially lift from the outer peripheral surface of the counter barrel 27 as in the prior art, the registration accuracy of the plate 38 in the vertical direction can be improved. In addition, since the processing by the processing cylinder 26 facing the counter cylinder 27 can be performed uniformly, the processing quality can be improved.

Next, an operation of processing the paper 2 conveyed by the counter cylinder 27 with the processing cylinder 26 in a state where the plate 38 is mounted on the counter cylinder 27 will be described. In advance, air is supplied to the pipe 100 from an air supply source (not shown), and the air supplied to the pipe 100 is supplied to the first air blowing nozzle 106 a of the first air blowing nozzle 106 and the second air blowing of the second air blowing nozzle 107. It blows out from the mouth 107a.

In this state, the paper 2 transferred from the gripping claw of the transfer cylinder 21F to the gripping claw 37 of the counter cylinder 27 and conveyed by the counter cylinder 27 passes through the first and the first before passing through the contact position A with the processing cylinder 26. Air blown from the first and second air blowing ports 106a and 107a of the second air blowing nozzles 106 and 107 is blown.

Therefore, even if the paper 2 transported by the counter cylinder 27 is fluttered, the first and second air blowing ports 106a and 107a of the first and second air blowing nozzles 106 and 107 are blown out. The fluttered air is corrected before the paper 2 conveyed to the counter cylinder 27 passes through the contact position A in contact with the processing cylinder 26. For this reason, since the processing accuracy by the processing cylinder 26 does not decrease and the registration accuracy in the vertical direction of the paper 2 does not decrease, the processing quality is improved.

The second air blowing port 107 a of the second air blowing nozzle 107 is provided upstream of the first air blowing port 106 a in the paper conveyance direction, and is directed to the paper 2 side conveyed by the counter cylinder 27. Therefore, even if the paper 2 transported by the counter cylinder 27 is blown larger than the fluttering, the paper 2 is blown by the air blown out from the second air blowing port 107a blown in the paper surface direction of the paper 2. And the synergistic effect with the air blown out from the first air blow-out port 106a improves the adhesion effect of the paper 2 to the plate 38 by the air. That is, a relatively large blow is first corrected by the air blown out from the second air outlet 107a. Next, since the first air blowing nozzle 106 having the first air blowing port 106a directed upstream in the paper conveyance direction further corrects the blow of the paper 2 in which the relatively large blow is corrected, the paper 2 Is processed by the processing cylinder 26 while being securely attached to the outer peripheral surface of the counter cylinder 27, the processing quality is further improved.

Next, the movement of the counter cylinder 27 to the reference position with respect to the processing cylinder 26 and the operation of changing the pressing amount by the pressing blade 172a of the pressing blade plate 172 attached to the processing cylinder 26 will be described. First, based on the height T of the pressing blade 172a of the pressing blade plate 172 attached to the processing cylinder 26 input to the blade height input means 169 in FIG. 12, the control device 170 moves the counter cylinder 27 to the cutting blade plate 172. A reference value corresponding to the reference position corresponding to the position at which the tip of the pressing blade 172a contacts the plate 38 mounted on the outer peripheral surface of the counter cylinder 27 is calculated.
Then, the adjustment value input to the gap amount input means 168 is added to or subtracted from this reference value to calculate a target value, and the detected value of the counter cylinder potentiometer 151 is compared with this target value,
If not, the adjustment motor 136 is driven in the forward or reverse direction until the detected value of the counter cylinder potentiometer 151 matches the target value, and the counter cylinder 27 is positioned at the set position.

That is, when the existing position of the counter cylinder 27 is closer to the processing cylinder 26 than the set position, the controller 170 drives the adjustment motor 136 in the positive direction. The rotation of the connecting shaft 138 that is rotated by this drive moves the rods 158A and 158B in the direction of arrow C in FIG. 10, so that the adjusting eccentric bearings 130A and 130B rotate in the counterclockwise direction in FIG. 9A ( FIG. 9A shows one adjusting eccentric bearing 130B (not shown).

By this rotation, the shaft core G3 of the counter cylinder 27 moves around the shaft core G4 of the adjusting eccentric bearings 130A and 130B. As a result, the counter cylinder 27 moves away from the process cylinder 26. The position of the counter cylinder 27 is detected by the counter cylinder potentiometer 151, and when this matches the target value calculated by the control apparatus 170, the control apparatus 170.
Stops driving the adjusting motor 136.

On the other hand, when the existing position of the counter cylinder 27 is located farther from the processing cylinder 26 than the set position, the controller 170 drives the adjustment motor 136 in the reverse direction. The rotation of the connecting shaft 138 that is rotated by this drive moves the rods 158A and 158B in the direction of arrow B in FIG. 10, so that the adjusting eccentric bearings 130A and 130B rotate in the clockwise direction in FIG. 9 (A) shows one adjusting eccentric bearing 130B).

By this rotation, the axis G3 of the counter cylinder 27 moves around the axis G4 of the adjusting eccentric bearings 130A and 130B. As a result, the counter cylinder 27 moves in a direction approaching the processing cylinder 26. The position of the counter cylinder 27 is detected by the counter cylinder potentiometer 151, and when this coincides with the target value calculated by the controller 170, the controller 170 stops the driving of the adjustment motor 136.

After the counter cylinder 27 is positioned at the set position, the processing of the paper 2 by the processing device 7, that is, punching by the pressing plate 172 of the processing cylinder 26 is performed. The operator inspects the paper 2 processed by the processing device 7 and inputs the gap amount to the gap amount input means 168 when the pressing amount needs to be changed. For example, if the amount of paper 2 to be cut is insufficient in the process of pushing the paper 2 with the pressing blade 172a, a negative gap amount is input to the gap input means 168 to further increase the push amount. In addition, if the amount of stamping is insufficient in the process of pressing off the sealing material and the adhesive layer that are stuck to the stripping agent without performing the stamping on the stripping agent, such as processing such as adhesive seals, in order to further increase the amount of pushing A gap amount which is a positive value but smaller than the currently inputted gap amount is input to the gap amount input means 168. Based on the changed gap amount and the reference value input to blade height input means 169, control device 170 calculates the changed target value and drives adjustment motor 136 in the reverse direction.

By driving the adjusting motor 136 in the reverse direction, the connecting shaft 138 and the rods 158A, 1
The eccentric bearings 130A and 130B for adjustment are rotated in the clockwise direction in FIG.
In FIG. 9A, one of the adjusting eccentric bearings 130B is not shown), and the shaft core G3 of the counter cylinder 27 is shown.
Moves around the axis G4 of the adjusting eccentric bearings 130A, 130B. As a result,
The counter cylinder 27 moves in a direction approaching the processing cylinder 26. The position of the counter cylinder 27 is detected by the counter cylinder potentiometer 151, and when this coincides with the changed target value, the control device 170 stops the driving of the adjustment motor 136.

Further, when the pressing amount of the pressing blade 172a is large, the gap amount input means 1 is used to reduce the pressing amount.
A gap amount larger than the gap amount input in 68 is input. Based on the changed gap amount and the reference value input to the blade height input means 169, the control device 170 calculates the changed target value and drives the adjustment motor 136 in the forward direction.

By driving the adjustment motor 136 in the positive direction, the connecting shaft 138 and the rods 158A, 1
The eccentric eccentric bearings 130A and 130B are rotated counterclockwise in FIG. 9A via 58B or the like (one of the eccentric eccentric bearings 130B is not shown in FIG. 9A). Shaft core G
3 moves around the axis G4 of the eccentric bearings 130A and 130B for adjustment. As a result, the counter cylinder 27 moves away from the process cylinder 26. The position of the counter cylinder 27 is detected by the counter cylinder potentiometer 151, and when this coincides with the changed target value, the control device 170 stops the driving of the adjustment motor 136.

In this way, the processing cylinder 26 is attached to and detached from the counter cylinder 27 on the processing cylinder 26 side, and the adjustment of the pressing force by the processing cylinder 26 on the paper 2 is performed on the counter cylinder 27 side.
A clearance provided between the frame and the bearing and between the bearing and the end shaft is shared by each of the cylinders 26 and 27.

Therefore, when the paper 2 passes between the counter cylinder 27 and the processing cylinder 26, the processing cylinder 26 moves upward within a clearance range provided between the frame and the bearing and between the bearing and the end shaft. This is because the clearance on the side of the processing cylinder 26 exists above due to the weight of the processing cylinder 26, so that there is room for upward movement, but the counter cylinder 27 disposed below the processing cylinder 26.
The clearance on the side exists above due to the weight of the counter cylinder 27, and even if the paper 2 passes between the counter cylinder 27 and the processing cylinder 26, the counter cylinder 27 is pressed downward with no clearance. Therefore, there is no play of the counter cylinder 27 due to the passage of the paper 2.

For this reason, the frame, one eccentric bearing, one eccentric bearing, and the other in a so-called double eccentric support structure in which the processing cylinder 26 is supported by an eccentric bearing for attachment and detachment and an eccentric bearing for adjusting the pushing amount as in the prior art. Compared with the clearance provided between the eccentric bearing and the other eccentric bearing and the end shaft, the clearance on the processing cylinder 26 side can be reduced, and as a result, the paper 2
This makes it possible to minimize the amount of movement of the processing cylinder 26 caused by the above processing. Therefore, it is possible to prevent a processing defect caused by the processing cylinder 26 on the paper 2 and improve the processing accuracy.

Further, the adjustment means 135 is adjusted by one adjustment motor 136 by moving the pair of left and right adjustment eccentric bearings 130A and 130B by the same amount simultaneously by the connecting shaft 138.
By doing so, it is not necessary to individually adjust the operation amounts of the pair of eccentric eccentric bearings 130A and 130B, so that the adjustment can be easily performed with high accuracy. Further, the control device 170 automatically adjusts the pressing force of the processing cylinder 26 on the paper 2 accurately by only inputting an input value to the gap amount input means 168 and / or the blade height input means 169 as the adjustment amount input means. can do.

When the processing cylinder 26 is removed from the counter cylinder 27, based on the machine phase detected by the rotary encoder 167, the controller 170 opens the processing cylinder attaching / detaching electromagnetic valve 166, and the processing cylinder attaching / detaching air cylinder 121. The rod 121a is retreated. With this retreat,
The detachable eccentric bearings 124A and 124B (one of the detachable eccentric bearings 124B is not shown) rotates counterclockwise in the drawing through the lever 123, so that the shaft core G1 of the processing cylinder 26 is attached to the detachable eccentric bearing. It moves around the axis G2 of 124A. As a result, a gap is formed between the outer peripheral surface of the counter cylinder 27 and the outer peripheral surface of the processing cylinder 26, and the cylinder is removed.

In this embodiment, the example in which the processing cylinder 26 is provided above the counter cylinder 27 has been described. However, the processing cylinder 26 may be provided below the counter cylinder 27, and in this case, the paper 2 is the processing cylinder. 2
When the counter cylinder 27 passes between the counter cylinder 27 and the counter cylinder 27, the counter cylinder 27 resists its own weight.
7 is lifted and moved by the clearance between the bearing and the end shaft. Accordingly, in this case as well, the amount of play of the counter cylinder 27 can be reduced as compared with the conventional double eccentric support structure, so that the accuracy of the pressing force by the processing cylinder 26 against the paper 2 can be improved, so that the processing cylinder. Therefore, it is possible to prevent a processing failure due to H.26.

Further, in the present embodiment, only the plate having the press cutting blade formed on the outer peripheral surface of the processing cylinder 26 has been described, but the press cutting blade, the crease blade, and the embossing die are provided, and the paper is punched and creased. It is good also as a processing plate which performs processing and embossing, and a plate material used for printing and coating. In this embodiment, the material to be processed by the plate mounted on the outer peripheral surface of the processing cylinder 26 is the paper 2, but it may be a film-like sheet or an aluminum plate formed in a thin plate shape. Moreover, it is good also as not only a sheet-like thing but a web.
