(Rotating mechanism)
The rotary receiving blade 751 is provided so as to rotate together with the drive shaft 64. The rotary sewing machine blade 701 is provided so as to rotate together with the rotary receiving blade 751 along with the conveyed paper at a position close to the rotary receiving blade 751.

(Width direction moving mechanism)
FIG. 11 is a perspective view of the upper body 71 as viewed from the upstream side. A screw shaft 61A is screwed into the upper protrusion 702 of the upper body 71, and the upper body 71 moves in the width direction (arrow W direction) along the guide shaft 63 when the screw shaft 61A rotates. It has become. The width direction is a direction orthogonal to the transport direction. Similarly, a screw shaft 66A is screwed into a lower protrusion 752 (see FIG. 9) of the lower body 75, and the lower body 75 moves in the width direction along the guide shaft 65A when the screw shaft 66A rotates.

(Up / down direction moving mechanism (contact / separation direction moving mechanism))
As shown in FIG. 9, the upper body 71 includes a cam member 721 and a swing lever 722. The cam member 721 is provided so as to rotate together with the cam rotation shaft 62. The swing lever 722 is interlocked with the cam member 721 located in the vicinity of the one end portion 7221 so that the other end portion (swing end portion) 7222 swings in the vertical direction (contact / separation direction) around the fulcrum 7223. It has become. A rotating sewing blade 701 is rotatably supported on the other end portion 7222. The other end portion 7222 is biased downward toward the receiving member (contact member) 7225 by the spring 7224 (biasing member), and thereby the one end portion 7221 is biased toward the cam member 721. ing. That is, when the cam member 721 rotates, the other end portion 7222 of the swing lever 722 swings in the vertical direction, whereby the rotary sewing blade 701 moves in the vertical direction, and thus the rotary sewing blade 701 is rotated by the rotary receiving blade. Moves toward and away from 751. FIG. 9 shows a state where the rotary sewing blade 701 is in an approach position with respect to the rotary receiving blade 751, and FIG. 12 shows a state where the rotary sewing blade 701 is in a separated position away from the rotary receiving blade 751.

  On the other hand, as shown in FIG. 7 showing the left side plate 513, a detection unit 723 is provided in the vicinity of one end of the cam rotation shaft 62. The detection unit 723 includes a light shielding plate 7231 that rotates together with the cam rotation shaft 62, and an optical sensor 7232 that detects switching between light transmission and light shielding by the light shielding plate 7231. The light shielding plate 7231 switches from light transmission to light shielding when the small diameter portion of the cam member 721 faces the one end portion 7221, and switches from light shielding to light transmission when the large diameter portion of the cam member 721 contacts the one end portion 7221. Or, it is set to switch to the reverse of these. When the small diameter portion of the cam member 721 faces the one end portion 7221, the height position of the other end portion 7222, that is, the rotary sewing machine blade 701, is the lowest position, that is, the approach position (see FIG. 9), and the large diameter portion of the cam member 721 is When abutting against the one end 7221, the height of the other end 7222, that is, the rotary sewing machine blade 701, is the uppermost position, that is, the separated position (see FIG. 12).

  The vertical direction moving mechanism of the perforated portion 7A is configured as described above. The up-and-down direction moving mechanism of the perforation processing portion 7B is similarly configured. The detection unit 723 is shared by the perforation processing units 7A and 7B.

(Adjustment mechanism)
A rod 725 is screwed into the upper portion 711 of the upper body 71 in the vertical direction. A receiving member 7225 is fixed to the lowermost end of the rod 725. A flange 7226 is fixed to the lower exposed portion of the rod 725 at a predetermined interval from the receiving member 7225, and a spring 7224 is disposed between the receiving member 7225 and the flange 7226. Therefore, when the other end portion 7222 is in contact with the receiving member 7225, that is, when the rotary sewing machine blade 701 is in the approach position, the spring 7224 is always maintained at a constant length. The other end portion 7222, that is, the rotary sewing machine blade 701 is urged with the same strength. A knob 7227 is provided at the upper end of the rod 725. When the knob 7227 is turned, the rod 725 moves up and down, whereby the height position of the receiving member 7225 is adjusted.

(Drive part)
The processing machine main body 10 is provided with a conveyance drive unit, a rotation drive unit, a width movement drive unit, and a vertical movement drive unit (contact / separation movement drive unit). Note that none of the driving units is shown. Therefore, the vertical movement drive unit is provided outside the perforation machining unit 51, that is, outside the movement region in the width direction of the perforation machining units 7A and 7B. Each of these driving units uses a motor. Further, the width movement drive unit uses a motor for the perforation processing unit 7A and a motor for the perforation processing unit 7B. These motors are preferably shared if they can be shared.

  When the perforation processing unit 51 is attached to the receiving portion 52, the rotation drive unit, the width movement drive unit, and the vertical movement drive unit are connected to the rotation mechanism, the width direction movement mechanism, and the vertical direction movement mechanism, respectively. It has become. This will be described with reference to FIGS. The rotation drive unit is connected to the gear 81. When the gear 81 rotates, the gears 82 and 83 connected to the gear 81 rotate. When the gear 83 rotates, the conveying roller 681 rotates, and the conveying roller 682 rotates following the rotation. On the other hand, as shown in FIG. 7, a pulley 891 is attached to the shaft end of the conveying roller 681, and a pulley 892 is attached to the end of the drive shaft 64. Both pulleys 891 and 892 are timings. The belts 893 are connected. Therefore, when the transport roller 681 rotates, the drive shaft 64 rotates through the pulley 891, the timing belt 893, and the pulley 892, and the rotary receiving blade 751 rotates. The gear ratio between the pulley 891 and the pulley 892 is set so that the peripheral speed of the transport roller 681 and the peripheral speed of the rotary receiving blade 751 are substantially equal. The width movement drive unit is connected to the gears 84A and 84B, respectively. When the gear 84A rotates, the screw shaft 61A rotates, and the screw shaft 66A connected by the annular belt 85A also rotates, thereby moving the perforated portion 7A in the width direction. When the gear 84B is rotated, the screw shaft 61B is rotated, and the screw shaft 66B connected by the annular belt 85B is also rotated, whereby the perforated portion 7B is moved in the width direction. The vertical movement drive unit is connected to the gear 86. When the gear 86 rotates, the cam rotation shaft 62 connected by the annular belt 87 rotates.

(Control part)
The control unit 6 controls the width movement driving unit and the vertical movement driving unit in accordance with the specified processing content. The rotation drive unit is always operated together with the pair of conveyance rollers 681 and 682 while the sheet is conveyed in the perforation processing unit 51. For example, in the case of machining contents as shown in FIG. 13, the control unit 6 performs the following control. The processing content shown in FIG. 13 is that the perforated portion M1 having the length L1 is formed at the first width position W1 and the second width position W2 of the sheet, and then the non-perforation having the length L2. A portion (a portion where no perforation is formed) N1 is placed, and a perforation portion M2 having a length L1 is further formed.

(A) When the width position for forming the perforation is designated, the control unit 6 controls the width movement driving unit. That is, when the first width position W1 and the second width position W2 that form the perforation are designated, the control unit 6 drives the motor for the perforation processing unit 7A by the first rotation speed R1, and the perforation. The motor for the processing unit 7B is driven by the second rotational speed R2. The first rotational speed R1 is set to a value necessary for rotating the screw shaft 61A and the screw shaft 66A to move the perforated portion 7A to the first width position W1. The second rotational speed R2 is set to a value necessary for rotating the screw shaft 61B and the screw shaft 66B to move the perforated portion 7B to the second width position W2.

(B) When the pattern for forming the perforation is designated, the control unit 6 controls the vertical movement driving unit. That is, it is designated that the control unit 6 forms the perforated portion M1 having the length L1, then places the non-perforated portion N1 having the length L2, and further forms the perforated portion M2 having the length L1. Then, the vertical movement drive unit is controlled as follows.

(b-1) When forming the perforated portion M1 having the length L1:
The control unit 6 drives the motor of the vertical movement drive unit. As a result, the cam member 721 rotates together with the cam rotation shaft 62, the other end portion 7222 of the swing lever 722 moves downward, and accordingly, the rotary sewing blade 701 moves downward and the rotation receiving blade 751. Approaching. When the detection unit 723 detects that the small diameter portion of the cam member 721 faces the one end portion 7221 of the swing lever 722, the control unit 6 stops driving the motor. As a result, the rotary sewing machine blade 701 moves to the lowest position (approach position). As a result, the rotary sewing blade 701 is taken with the conveyed paper and rotates together with the rotary receiving blade 751 to form a perforation. The control unit 6 maintains this state for the first time T1. The first time T1 is a time required for the perforation to be formed by the length L1.

(b-2) When placing a non-perforated portion N1 of length L2:
The control unit 6 drives the motor of the vertical movement drive unit when the first time T1 has elapsed. As a result, the cam member 721 rotates together with the cam rotation shaft 62, the other end portion 7222 of the swing lever 722 moves upward, and accordingly, the rotary sewing blade 701 moves upward and the rotation receiving blade 751. Get away from. When the detection unit 723 detects when the large diameter portion of the cam member 721 contacts the one end portion 7221 of the swing lever 722, the control unit 6 stops driving the motor. As a result, the rotary sewing blade 701 moves to the uppermost position (separated position). Thereby, the rotary perforation blade 701 does not rotate, and therefore no perforation is formed. The control unit 6 maintains this state for the second time T2. The second time T2 is a time required for the perforation not to be formed by the length L2.

(b-3) When forming the perforated portion M2 having the length L1:
When the second time T2 has elapsed, the control unit 6 drives the motor of the vertical movement drive unit. As a result, the cam member 721 rotates together with the cam rotation shaft 62, the other end portion 7222 of the swing lever 722 moves downward, and accordingly, the rotary sewing blade 701 moves downward and the rotation receiving blade 751. Approaching. When the detection unit 723 detects that the small diameter portion of the cam member 721 faces the one end portion 7221 of the swing lever 722, the control unit 6 stops driving the motor. As a result, the rotary sewing machine blade 701 moves to the lowest position (approach position). As a result, the rotary sewing blade 701 is taken with the conveyed paper and rotates together with the rotary receiving blade 751 to form a perforation. The control unit 6 maintains this state for the first time T1.

[Operation]
In the paper processing machine 1, the paper in the paper supply unit 11 is transported on the transport path 20 in accordance with control by the control unit 6, while the first processing device 3, the second processing device 4, and the third processing device (perforation processing). In the apparatus 5, the sheets are sequentially processed and discharged to the paper discharge unit 12.

  At that time, the perforation processing device 5 operates as follows.

(Before operation)
Processing contents for perforation formation on the paper are designated in advance. This designation is normally performed by the operator via the operation panel. The processing content is as shown in FIG. 13 described above. In addition, the initial state of the vertical movement mechanism in the perforation processing portions 7A and 7B is a state in which the rotary perforation blade 701 is in an approach position with respect to the rotary receiving blade 751.

  The control unit 6 controls the width movement driving unit as described above. As a result, the perforated portion 7A moves to the first width position W1, and the perforated portion 7B moves to the second width position W2.

(In operation)
(1) When the sheet is conveyed, the control unit 6 drives the motor of the rotation driving unit for the first time T1. When the motor of the rotation drive unit is driven, the drive shaft 64 rotates in the perforation processing units 7A and 7B, and the rotary perforation blade 701 is rotated along with the rotary receiving blade 751 along with the conveyed paper. Thereby, the perforation part M1 of length L1 is formed.

(2) When the first time T1 has elapsed, the control unit 6 drives the motor of the vertical movement drive unit. When the motor of the vertical movement drive unit is driven, the cam rotation shaft 62 rotates in the perforation processing units 7A and 7B, the cam member 721 rotates, and the other end portion 7222 of the swing lever 722 moves upward (separating direction). ) And the rotary sewing blade 701 moves away from the rotary receiving blade 751. Thereby, no perforation is formed. When the detection unit 723 detects when the large-diameter portion of the cam member 721 contacts the one end portion 7221, the control unit 6 stops driving the motor. Thereby, the rotary sewing machine blade 70 is in the uppermost position. The control unit 6 maintains this state for the second time T2. Thereby, a non-perforated portion N1 having a length L2 is formed.

(3) When the second time T2 has elapsed, the control unit 6 drives the motor of the vertical movement drive unit. When the motor of the vertical movement drive unit is driven, the cam rotation shaft 62 rotates in the perforation processing units 7A and 7B, the cam member 721 rotates, and the other end portion 7222 of the swing lever 722 moves downward (approach direction). ) And the rotary sewing machine blade 701 approaches the rotary receiving blade 751. When the detection unit 6 detects when the small diameter portion of the cam member 721 faces the one end portion 7221, the control unit 6 stops driving the motor. As a result, the rotary sewing blade 701 becomes the lowermost position, that is, the approach position with respect to the rotary receiving blade 751. The control unit 6 maintains this state for the first time T1. As a result, a perforated portion M2 having a length L1 is formed.

[Function and effect]
The perforation processing device 5 configured as described above can exhibit the following operational effects.

(A) Since the vertical movement mechanism and the vertical movement drive unit are provided, the rotary sewing machine blade 701 can be brought into contact with and separated from the rotary receiving blade 751 that is rotationally driven. A perforation is formed when the rotary sewing blade 701 is in an approach position with respect to the rotary receiving blade 751, and a perforation is not formed when the rotary sewing blade 701 is in a separated position away from the rotary receiving blade 751. Therefore, the perforation is not always formed on the paper, and the perforation can be formed or not formed.

(B) The vertical movement mechanism is composed of a cam rotation shaft 62, a cam member 721 provided on the upper body 71, a swing lever 722, and the like. That is, it is provided outside the perforation processing unit 51, that is, outside the movement region in the width direction of the perforation processing portions 7A and 7B. Therefore, it is possible to solve the problems that the conventional solenoid mechanism has. That is, problems such as high cost, large equipment, and complicated structure can be solved.

(C) By changing the shape of the cam member 721, the swing characteristic of the swing lever 722 can be easily changed.

(D) Since the height position of the receiving member 7225 can be adjusted by the adjusting mechanism, the lowest position of the rotary sewing machine blade 701 can be adjusted. Therefore, the pushing amount of the perforation can be adjusted.

(E) When the rotary sewing machine blade 701 is at the lowest position, the spring 7224 always has a constant length. . Therefore, when the perforation is formed at the lowest position, the rotary sewing blade 701 can always be brought into contact with the paper with the same strength. Therefore, the perforation can be formed accurately.

(F) The rotation driving unit always operates together with the pair of conveyance rollers 681 and 682 while the sheet is conveyed in the perforation processing unit 51. That is, the paper is also conveyed when the rotary sewing blade 701 is brought into contact with and separated from. Therefore, processing for forming perforations can be performed in a short time.

  The paper processing machine 1 configured as described above can exhibit the following operational effects.

(F) Since the perforation processing unit 51 is detachable from the processing machine main body 10, it is easy to handle. For example, when a jam occurs, it can be easily handled. Also, it can be easily replaced with another processing unit.

(G) Since the drive unit, that is, the rotation drive unit, the width movement drive unit, the vertical movement drive unit, and the like are provided in the processing machine body 10, the following effects can be exhibited.
(g-1) It is possible to reduce the vibration caused by the drive unit from being transmitted to the rotation mechanism, the width direction movement mechanism, the vertical direction movement mechanism, and the like by the solid processing machine body 10. Therefore, the operation of each mechanism can be executed stably, and accurate perforation can be realized.
(g-2) Noise due to vibration can be reduced, and therefore a good working environment can be realized.
(g-3) The drive unit can be shared with other processing units, and therefore the paper processing machine 1 can be configured in a compact and inexpensive manner.

[Modification]
(First variant)
A one-way clutch (not shown) is provided between the cam rotation shaft 62 and the cam member 721 in the perforation processing portions 7A and 7B. The one-way clutch of the perforated portion 7A and the one-way clutch of the perforated portion 7B are set so as to perform rotation control in opposite directions. Others are the same as the above-mentioned embodiment.

  According to the above configuration, by rotating the cam rotation shaft 62 in one direction, only the cam member 721 of the perforated portion 7A can be rotated, and by rotating the cam rotation shaft 62 in the other direction. Only the cam member 721 of the perforated portion 7B can be rotated. Therefore, the one cam rotation shaft 62, that is, one vertical movement drive unit, makes the perforation operation of the rotary perforation blade 701 of the perforation machining portion 7A to the rotary receiving blade 751, and the rotation perforation blade of the perforation machining portion 7B. The contact / separation operation with respect to the rotary receiving blade 751 of 701 can be performed separately. Therefore, it is possible to freely form or not form the perforation at each perforation processing portion 7A, 7B, and increase the degree of freedom of the perforation formation pattern.

  The reason why the one-way clutch can be used in this way is that, in the up-and-down direction moving mechanism, the cam member 721 is configured to operate regardless of which of the two directions rotates.

  In addition, according to the above configuration, the vertical movement mechanism capable of separately executing the contact / separation operations can be realized by the single cam rotating shaft 62, so that the performance of the apparatus can be improved at a low cost.

(Second modification)
FIG. 14 and FIG. 15 are a right perspective view and a left perspective view of the perforation processing unit of the present modification as seen from the upstream side. In the machining unit 51, two cam rotation shafts 62A and 62B are provided in parallel. Further, the guide shaft 63 is not provided. Others are the same as the above-mentioned embodiment. 14 and 15, the top plate 511 and the bottom frame 514 are not shown.

  One cam rotation shaft 62A is provided so as to rotate together with the cam member 721 of the perforation machining portion 7A, and the other cam rotation shaft 62B is provided so as to rotate together with the cam member 721 of the perforation machining portion 7B. It has been. The two cam rotation shafts 62A and 62B are each independently driven by a vertical movement drive unit. The vertical movement drive unit is connected to the gear 88A to rotate one cam rotation shaft 62A, and is connected to the gear 88B to rotate the other cam rotation shaft 62B.

  According to the above configuration, the contacting / separating operation of the rotary perforation blade 701 with respect to the rotary receiving blade 751 of the perforation machining portion 7A and the contacting / separating operation of the rotary perforation blade 701 with respect to the rotary receiving blade 751 of the perforation processing portion 7B are completely performed. For example, can be performed separately at the same time. Therefore, it is possible to freely form or not form the perforation in each perforation processed portion 7A, 7B, and the degree of freedom of the perforation formation pattern can be further increased.

(Third variant)
As shown in FIG. 16, the sponge roller 91 is juxtaposed with the rotary sewing machine blade 701. The sponge roller 91 is provided so as to rotate integrally with the rotary sewing machine blade 701. The sponge roller 91 has an outer diameter that is slightly larger than the outer diameter of the rotary sewing machine blade 701. Others are the same as the above-mentioned embodiment.

  The outer diameter of the sponge roller 91 is preferably about 2 mm larger than the outer diameter of the rotary sewing blade 701. The material of the sponge roller 91 is preferably silicon rubber, and in particular, Asker C having a hardness of about 35 is preferable.

  According to the above configuration, since the sponge roller 91 presses the paper before the rotary sewing blade 701 is pushed into the paper, the perforation can be formed cleanly even when the paper is thin. Further, even when the rotary sewing blade 701 moves away from the paper, the sponge roller 91 still holds the paper, so that the rotary sewing blade 701 can be reliably pulled away from the paper without drawing the paper.

  The sponge rollers 91 are preferably provided on both sides of the rotary sewing blade 701. However, even in the case of FIG. 16 provided only on one side of the rotary sewing blade 701, the above-described effects can be sufficiently exhibited.

  Conventionally, a guide member has been used to reliably pull the rotary sewing blade 701 away from the paper. However, according to this modification, since the sponge roller 91 is used, a guide member is unnecessary, and the apparatus configuration can be simplified. However, the sponge roller 91 may be used in combination with a guide member.

(Other variations)
(1) The perforation processing apparatus may be configured to have three or more perforation processing portions.

(2) The perforation device may be configured to drive the rotary receiving blade 751 and the conveying roller 681 separately. Further, when the rotary sewing machine blade 701 operates to contact and separate, the drive of the rotary receiving blade 751 and the conveyance roller 681 may be stopped. According to this, since the paper is stopped when the rotary sewing blade 701 is brought into contact with and separated from, the accuracy of the start position and the end position of the formed perforation can be improved.

(3) The perforation processing device 5 of the above embodiment is configured such that the contact / separation direction is the vertical direction. However, the perforation processing apparatus may be configured such that the contact / separation direction is a horizontal direction or an oblique direction.

(4) The perforation processing device 5 of the above embodiment is configured such that the rotary receiving blade 751 is rotationally driven. However, the perforation device may be configured such that both the rotary perforation blade 701 and the rotary receiving blade 751 are not rotationally driven. In this case, the two blades are rotated with the conveyed paper.

(5) The detection unit of the perforation device may be configured to detect the approach position and the separation position of the rotary perforation blade 701 by measuring the number of rotations (rotation amount) of the motor of the vertical movement drive unit. Good.

(6) The receiving member (contact member) 7225 of the perforation processing device 5 of the embodiment is in contact with the other end portion 7222 of the swing lever 722 from below. However, such a contact member may be provided so as to contact from any direction as long as the downward movement of the other end portion 7222 of the swing lever 722 can be restricted.

  Since the perforation processing device of the present invention can solve the problems of the conventional solenoid mechanism, the industrial utility value is great.
