Description

  The present invention relates to a paper processing apparatus for cutting continuous paper that is being conveyed.

  Conventionally, continuous paper capable of handling a large amount of paper (also called cut paper) in the form of roll paper or the like has been used for a large amount of high-speed printing. In this continuous paper processing system, a continuous paper supply device and a post-processing device which are printed and wound in a roll form from a continuous paper supply device via a printing machine and a printer device (including a rotary press and a digital printer) are installed. By combining them, post-processing such as paper cutting, bookbinding, binding, insertion, sealing, etc., can be performed on the printed matter according to the purpose.

  In the cutting unit that performs continuous paper cutting, the continuous paper is cut in the length direction (conveyance direction) and the width direction (direction orthogonal to the conveyance direction) of the continuous paper, and processing to match a predetermined paper size is performed. A waste paper storage box called purge is provided downstream of the cutting unit in the continuous paper conveyance direction, and unnecessary cut pieces (unnecessary parts) cut by the cutting unit are placed therein. On the other hand, the paper in the print job is conveyed to a post-processing machine downstream of the cutting unit, or is guided to a predetermined stacker by switching the paper conveyance path for each application.

  In these processes on continuous paper, it is required to cut the continuous paper to a required size while transporting the continuous paper at a high speed and transport it to a necessary processing unit.

  For this reason, the cutting along the conveyance direction of the continuous paper is generally performed by a slitter having a tooth surface protruding on the conveyance surface. On the other hand, the continuous paper width direction cutting is not a movable cutter type that can be easily accommodated to any size with the continuous paper stopped, as used in a relatively low speed paper cutting mechanism such as CAD and facsimile. A rotary cutter is often used that has cutter teeth over the entire width of the continuous paper, and can rotate the entire width of the continuous paper at the same time by rotating the cutter teeth arranged in a shaft (for example, patents). Reference 1).

  However, since the cutting mechanism cuts the entire width of the continuous paper in a batch with the rotary cutter shaft, a cutting operation that changes the dimension in the width direction of the continuous paper to be cut cannot be performed. Even if the slitter cuts along the conveying direction of the continuous paper, the entire width is cut at once by the rotary cutter, so if the cutting pitch is different for each cut continuous paper, cutting by the slitter After the processing, it is necessary to largely separate the conveyance positions of the respective continuous sheets, and to convey one continuous sheet to another sheet cutting means via a different sheet conveyance path for processing.

  Even in the continuous paper processing system described above, there is an increasing demand for variable post-processing machines that process a large amount of each different but at a high speed, especially for DM printing and invoices, such as the issuance of a small number of printed materials on demand. Yes.

  Among these, there is a requirement to process forms with different paper sizes at once, but the continuous paper processing system is not easy to switch paper sizes compared to cut papers due to the form of the paper, and it is faster. It was difficult to carry out continuous paper cutting in a variable and high-speed manner in correspondence with various print outputs while maintaining the same.

  For example, different form forms cannot be processed together, and the setup work required between jobs due to frequent paper size changes not only causes a significant decrease in total performance, Replacement and setup led to wasted paper consumption.

  In particular, when paper is cut in a variable manner, various various sizes are sent continuously at high speed, so accurate sorting is required for post-processing such as folding, binding, and binding for each paper size after cutting. However, at present, papers with different paper sizes cannot be sorted accurately while maintaining high speed, so if the size is changed, the process is temporarily suspended and the settings can be changed or the continuous paper can be switched. Had to do.

  When the continuous paper is cut to a variable position in the direction of transporting the continuous paper or in the width direction of the continuous paper, it is necessary to control the sorting portion to be variable. In addition, if a paper jam occurs in the sorting portion, in addition to removing or replacing the paper. Therefore, reprinting (recovery) including editing of an unpost-processed printed page including a jam page is required. For this reason, not only the total performance declines, but also a fatal error output such as missing pages or duplication. Therefore, when the paper size is changed, the sorting part is cut to the boundary part of the sorting flapper. Although a large margin distance is required between the paper edges, it has not been easy to ensure this.

  Here, there is a system that uses cut paper as a system that sorts paper at an arbitrary size. However, since cut paper is stored in a paper feed cassette or the like, the paper size is known at the time of paper transport, In addition, the individual sheets are spaced apart from each other by a predetermined distance in the conveyance direction, and a plurality of sheets are not simultaneously subjected to different processes in a direction orthogonal to the sheet conveyance direction.

  However, a processing system that uses continuous paper meets the demand for high speed that cannot be handled by cut paper, and processing a plurality of processes simultaneously is indispensable in order to maximize the advantages.

  Conventionally, in order to switch the paper size in the width direction of the continuous paper, it is necessary to change the continuous paper itself or to adjust the position of the teeth of the cutter mechanism, which takes a long time and impairs the high speed. In addition, a large amount of paper is required for position adjustment, and a continuous paper joint sometimes causes a problem in the downstream post-processing machine.

  In addition, even when switching the size in the conveyance direction of continuous paper, it is cut in a batch with a rotary cutter etc. adopted for high speed correspondence, and it can not be cut into different sizes with a single device, The system becomes much more complicated and expensive as the processing becomes more complicated, such as separating and transporting paper cut in the continuous paper transport direction to different post-processing machines and cutting it with a separate cutting device. Not only that, there was a significant decline in operating efficiency.

  Here, in order to cut the continuous paper in a variable manner while maintaining high speed, cutting information for cutting with a variable paper size is required. However, continuous paper processing systems also have post-processor systems that are generally faster than printing systems, and in order to ensure versatility of installation and operation, once printed output paper is wound up into a roll, and the printing device In general, a post-processing machine system that has been cut off is cut into a required paper size and the subsequent post-processing is performed. In the case of such an operation method, it is impossible to transmit paper size information from the print output device through an interface or the like and control cutting of the continuous paper according to the information.

  Therefore, in the conventional high-speed continuous paper processing system, the cutting position along the conveyance direction of the continuous paper is fixed, and the cutting position in the width direction of the continuous paper is marked with paper cutting information according to the paper size at the time of printing, The paper was cut accordingly. For this reason, it has not been possible to cope with a condition in which the paper size changes to be variable.

Also, some low-speed plotters, facsimile machines, and the like are low-speed and can stop paper conveyance, so that some cutting positions are indicated by marks and the paper is cut at the designated location. However, since the paper sizes used in these devices are determined in advance such as A-series and B-series and are integrated with the output device, the paper size information and cutting information from the output device are interfaced. It is controlled by transmitting via. Although a method of designating a cutting position with a bar code is also disclosed (Patent Document 2), a method of performing cutting position control for variable paper cutting is not considered.

[First Embodiment]
The sheet processing apparatus according to the first embodiment will be described below.

<Paper handling device>
Here, the sheet processing apparatus 10 will be described.

  As shown in FIG. 1 to FIG. 3A and FIG. 3B, the sheet processing apparatus 10 has a slitter unit (first portion) that cuts the continuous paper P along the conveyance direction of the continuous paper P on the upstream side. Cutting means) 20 is provided. A cutter unit (second cutting unit) 22 that cuts the continuous paper P along a direction (width direction of the continuous paper P) orthogonal to the conveyance direction of the continuous paper P is disposed on the downstream side of the slitter unit 20. ing.

(Slitter part)
As shown in FIGS. 2 and 3, the slitter unit 20 includes slitters 32, 34 disposed along the width direction of the continuous paper P to be conveyed on the upstream side in the frame 30 of the paper processing apparatus 10. 36, each of the slitters 32, 34, 36 has a substantially disk shape, and the blade portion protrudes from the conveying surface of the continuous paper P. A plurality of transport rollers are disposed on the transport surface along the transport direction of the continuous paper P, but the illustration is omitted.

  For convenience of explanation, the slitters 32 and 34 disposed on both ends in the width direction of the continuous paper P to be conveyed are referred to as side slitters 32 and 34, and the slitter 36 disposed in the center in the width direction of the continuous paper P. Is called a center slitter 36. Although three slitters are provided here, only the center slitter 36 may be provided, or two center slitters 36 may be provided.

  On the support plate 30 </ b> A located on the upstream side of the frame body 30, a pair of shaft support plates 38 and 40 extend along the conveyance direction of the continuous paper P on both ends of the continuous paper P to be conveyed. A pair of shaft support plates 42 are disposed between the shaft support plate 38 and the shaft support plate 40. The shaft support plates 42 are provided on a support 44 of the cutter unit 22 described later. Will be described later.

  A shaft 46 passes through the shaft support plates 38, 42, and 40, and is rotatable with respect to the shaft support plates 38, 42, and 40. Side slitters 32 and 34 fixed to a shaft 46 are provided between the shaft support plate 38 and the shaft support plate 38 and between the shaft support plate 40 and the shaft support plate 40, respectively. Between the support plates 42, a center slitter 36 (which will be described later) that is prevented from rotating by a shaft 46 is provided.

  A pulley 48 is provided at one end of the shaft 46, and a drive belt 50 is wound around the pulley 48. The drive belt 50 is wound around a pulley 54 connected to a drive motor 52 provided on the frame 30, and the drive force from the drive motor 52 is passed through the pulley 54, the drive belt 50 and the pulley 48. To the shaft 46. As the shaft 46 rotates, the side slitters 32 and 34 and the center slitter 36 rotate.

  Then, both end portions in the width direction of the continuous paper P are cut off by the side slitters 32 and 34, but the cut-off area is stored in the waste paper storage box 58 (see FIG. 1) as an unnecessary portion 56 shown in FIG. The Further, the continuous paper P is divided into continuous papers A and B (two in this case) in the width direction by the center slitter 36 and conveyed to the cutter unit 22 side.

  Here, the unnecessary portion 56 is accommodated in the waste paper storage box 58 on the upstream side of the cutter portion 22, but the unnecessary portion 56 is accommodated in the waste paper storage box 58 on the downstream side of the cutter portion 22. You may make it do. Although the unnecessary part 56 accommodated on the upstream side of the cutter part 22 is continuous, the unnecessary part 56 accommodated on the downstream side of the cutter part 22 has a chip shape.

  Further, although not shown, the shaft 46 (see FIG. 2) is composed of a plurality of pieces and is connected to each other by an electromagnetic coupling 47 (see FIG. 5). The coupling 47 is connected to a control unit 88 (see FIG. 5) that controls the paper processing system 12. When the coupling 47 is in a conductive state, the shafts are coupled to each other via the coupling 47. Is not connected so that the driving force from the drive motor 52 is not transmitted.

  On the other hand, the side slitter 34 is provided so as to be retractable with respect to the transport surface of the continuous paper P to be transported, and can be retracted by a solenoid 35 (see FIG. 5) connected to the control unit 88.

  Specifically, when the solenoid 35 is in an OFF state, the side slitter 34 is in a cut state and is positioned below (on the conveyance surface side of the continuous paper P to be conveyed) and continuously conveyed when the coupling 47 is in a conductive state. The paper P is cut, but when the coupling 47 is in a non-conductive state and the solenoid 35 is turned on, the side slitter 34 moves upward, and a gap is provided between the continuous paper P being conveyed and the non-cut state. It is said.

  For example, there is a case where it is not necessary to cut the continuous paper P by the side slitter 34, such as when the unnecessary portion 56 is formed from the cutting position of the center slitter 36 of the continuous paper P to one end side (see FIG. 8). In this case, the side slitter 34 is not cut.

  However, when both ends of the continuous paper P are surely cut, the side slitter 34 is not necessarily removed even if the continuous paper P from the cutting position of the center slitter 36 to the one end side becomes the unnecessary portion 56. It is not necessary to be in a disconnected state. In this case, a device such as a solenoid 35 for moving the side slitter 34 up and down is unnecessary.

  Here, only the side slitter 34 can be switched to the cut state or the non-cut state. However, all slitters may be switched to the cut state or the non-cut state.

  Furthermore, although the shaft 46 is composed of a plurality of shafts and can be connected to each other by an electromagnetic coupling 47, a driving means such as a motor is provided for each of the side slitters 32 and 34 and the center slitter 36 to make them independent from each other. You may make it drive in the state.

(Cutter part)
As shown in FIG. 2 and FIG. 3, the cutter unit 22 is provided with a frame-shaped support body 44, and a pair of surfaces provided to face each other along the width direction of the continuous paper P to be conveyed. Support plates 44A and 44B and support plates 44C and 44D for connecting both ends of the support plates 44A and 44B are provided.

  One shaft 60 passes through the support plates 44C and 44D and is fixed to the side wall 30B of the frame 30. As an example, the support plates 44C and 44D have a shaft hole 62 portion through which the shaft 60 passes and can be divided in the vertical direction. After the shaft 60 is supported on the lower side of the shaft hole 62, the support plates 44C and 44D The upper side of the shaft hole 62 of 44D is fixed to the lower side.

  On the other hand, the cutter unit 22 includes a plurality of cutting units 64 and 66 (two in this embodiment) along the width direction of the continuous paper P. The cutting portions 64 and 66 have a substantially cylindrical shape having the same length, and blade portions 64A and 66A are formed along the axial direction of the outer peripheral surfaces of the cutting portions 64 and 66, respectively.

  The blade portions 64A and 66A are slightly inclined along the axial direction. This is to reduce the load applied by the blade portions 64A and 66A when the continuous paper P is cut. The angle is larger than the actual angle.

  The cutting portions 64 and 66 are inserted through the shaft 60, respectively. As shown in FIG. 6 (FIG. 6 is a cross-sectional view showing the periphery of the shaft 60 of the cutter unit 22), the cutting parts 64 and 66 are interposed via bearings 68 and 70 disposed on the shaft 60. Each of the shafts 60 is rotatable. Small diameter portions 72 and 74 are provided outside the cutting portions 64 and 66, respectively, and pulleys 76 and 78 are provided at end portions of the small diameter portions 72 and 74, respectively.

  Here, since the pulleys 76 and 78 are disposed outside the support plate 44B, the small diameter portions 72 and 74 are pivotally supported by the support plates 44C and 44D. For this reason, a bearing 80 is provided in the shaft hole 62 of the support plates 44C and 44D, and the cutting portions 64 and 66 can be rotated with respect to the shaft hole 62 via the bearing 80, respectively.

  As shown in FIGS. 2 and 3, a driving belt 82 is wound around the pulley 76, and the driving belt 82 is connected to a pulley 86 connected to a driving motor 84 provided on the support plate 44C. The driving force from the driving motor 84 is transmitted to the cutting portion 64 via the pulley 86, the driving belt 82 and the pulley 76.

  The drive motor 84 is connected to a control unit 88 (see FIG. 5) that controls the paper processing system 12, and is driven according to an instruction from the control unit 88. When the drive motor 84 is driven, the cutting portion 64 is rotated via the pulley 86, the drive belt 82, and the pulley 76. By this rotation, the continuous paper P conveyed under the cutting unit 64 is cut by the blade part 64A of the cutting part 64 (rotary cutter).

  On the other hand, a driving belt 90 is wound around the pulley 78, and the driving belt 90 is wound around a pulley 102 connected to a driving motor 100 provided on the support plate 44D. The force is transmitted to the cutting part 66 through the pulley 102, the drive belt 90 and the pulley 78.

  Similarly to the drive motor 84, the drive motor 100 is connected to the control unit 88 of the paper processing system 12 and is driven according to an instruction from the control unit 88. When the drive motor 100 is driven, the cutting unit 66 is rotated via the pulley 102, the drive belt 90, and the pulley 78. By this rotation, the continuous paper P is cut by the blade part 66A of the cutting part 66 (rotary cutter).

  That is, the cutting parts 64 and 66 are individually provided with drive motors 84 and 100 for driving the cutting parts 64 and 66, respectively, so that the cutting parts 64 and 66 can be rotated independently. The drive motors 84 and 100 can be synchronized with each other, and can cut the entire width of the continuous paper P that is conveyed with the cutting portions 64 and 66 integrated.

  On the other hand, the support body 44 is provided so as to be movable along the width direction of the continuous paper P being conveyed. Specifically, a connecting portion (not shown) is provided on the outer surface of the support plate 44B, and the driving belt 104 disposed along the width direction of the continuous paper P conveyed with the connecting portion is: Are connected to each other.

  The drive belt 104 is wound around pulleys 106 and 108 disposed at both ends in the width direction of the continuous paper P. When the stepping motor 110 connected to the pulley 106 is driven, the drive belt 104 is passed through the pulleys 106 and 108. Thus, the connecting portion of the drive belt 104 moves a predetermined amount along the width direction of the continuous paper P to be conveyed (see FIGS. 7A and 7B).

  And the support body 44 moves along the width direction of the continuous paper P conveyed through this connection part. Here, the stepping motor 110 is connected to the control unit 88 (see FIG. 5) of the paper processing system 12 and is driven in accordance with an instruction from the control unit 88.

  Here, an unnecessary portion 57 (see FIGS. 10A and 10B) is formed on the continuous paper P by an instruction from the control portion 88, and the support body 44 is moved within the region of the unnecessary portion 57. That is, in the continuous paper P, the support body 44 moves while the unnecessary portion 57 passes. The unnecessary portion 57 is accommodated in the waste paper storage box 58 (see FIG. 1). However, when printing is performed on the upstream side of the slitter portion 20, the unnecessary portion 57 performs printing according to an instruction from the control portion 88. It is not done and it becomes the state of a blank paper.

  In this case, the pulleys 106 and 108 and the driving belt 104 are used to move the support body 44. However, there is no particular limitation as long as the support body 44 can be moved. For example, a sprocket and a chain may be used instead of the pulleys 106 and 108 and the driving belt 104, or a mechanism using a pinion and a rack may be used.

  On the other hand, at the center of the outer surface of the support plate 44 </ b> A, a pair of shaft support plates 42 extend along the conveyance direction of the continuous paper P. A center slitter 36 of the slitter unit 20 is rotatably supported on the shaft support plate 42. For this reason, when the support body 44 moves, the position of the center slitter 36 also changes via the shaft support plate 42.

  Therefore, when the position of the center slitter 36 of the slitter unit 20 and the position of the boundary part P of the cutting unit 64 and the cutting unit 66 of the cutter unit 22 are first matched, the position of the center slitter 36, the cutting unit 64, and the cutting unit 66 always coincides with the position of the boundary P.

  Here, on the outer peripheral surface of the shaft 46 of the center slitter 36, a groove portion (not shown) is formed along the axial direction of the shaft 46, and the center slitter 36 has a protrusion that fits with the groove portion. When the shaft 46 rotates, the center slitter 36 rotates integrally with the shaft 46 through the groove and the protrusion. When the center slitter 36 moves, the protrusion moves in the groove, and the center slitter 36 moves in the axial direction of the shaft 46. The position can be changed.

  Further, on the outer side of the shaft support plate 42, a feeding roller (feeding) disposed obliquely on the downstream side of the slitter unit 20 so as to go outward from the upstream side to the downstream side of the conveyed continuous paper P. Means) 112 are respectively arranged so as to come into contact with the continuous paper P cut by the center slitter 36 and to feed the continuous paper P away from each other. The delivery roller 112 is also provided integrally with the support body 44, and moves with the movement of the support body 44.

  As described above, the sheets a and b cut to a predetermined size by the slitter unit 20 and the cutter unit 22 of the sheet processing apparatus 10 are transferred by the sheet guide apparatus 24 disposed on the downstream side of the sheet processing apparatus 10. Guided to the paper stacks 26 and 28, respectively.

<Paper guide device>
As shown in FIG. 2, the sheet guide device 24 is provided with guide members 114 and 116 corresponding to the respective sheets a and b divided in the width direction by the slitter unit 20, and the slitter unit 20. Then, the sheets a and b cut to a predetermined size by the cutter unit 22 are respectively guided to the sheet stacks 26 and 28 disposed on the downstream side.

  The guide members 114 and 116 are formed in a plate shape, and the upstream side of the guide members 114 and 116 in the transport direction of the sheets a and b is inclined downward, and the leading ends of the transported sheets a and b. The part is not caught. Further, on the downstream side of the guide members 114 and 116 in the conveyance direction of the sheets a and b, shaft portions 118 are provided along the width direction of the guide members 114 and 116 (width direction of the continuous paper P being conveyed), respectively. It has been.

  A shaft hole 120 passes through the shaft portion 118, and one shaft 122 fixed to a shaft support plate (not shown) is inserted into the shaft hole 120, and guide members 114 and 116 are inserted into the shaft 122. Is rotatable. From the side end surfaces of the guide members 114 and 116 on the free end side, pressing pieces 124 and 126 project along the width direction of the guide members 114 and 116.

  Racks 115 and 117 are provided on the shaft 118 side of the guide members 114 and 116, respectively, and the pinions 119 and 121 mesh with the racks 115 and 117, respectively. The pinions 119 and 121 are connected to drive motors 123 and 125, respectively. When the drive motors 123 and 125 are driven, the pinions 119 and 121 rotate and are guided by the pinions 119 and 121 through the racks 115 and 117, respectively. The members 114 and 116 move along the width direction of the sheets a and b being conveyed.

  The drive motors 123 and 125 are connected to the control unit 88 (see FIG. 5) of the paper processing system 12 and are driven in accordance with instructions from the control unit 88. By synchronizing the drive motors 123 and 125 so that the guide member 114 and the guide member 116 are always moved at the same speed, the end surface of the guide member 114 and the end surface of the guide member 116 are always in contact with each other. It is possible to prevent a gap from being formed between the guide member 116 and the guide member 116. The boundary Q between the guide member 114 and the guide member 116 can be adjusted to the position of the center slitter 36 by the movement of the guide member 114 and the guide member 116.

  Here, the guide member 114 and the guide member 116 are provided with moving means (racks 115 and 117, pinions 119 and 121 and drive motors 123 and 125), respectively, but the guide member 114 and the guide member 116 are always together. In order to move, the guide member 114 and the guide member 116 may be moved via the guide member 114 (or the guide member 116) using power transmission means such as a pulley and a belt.

  On the other hand, the tip portions of the plungers 130 and 131 of the solenoids 128 and 129 come into contact with the upper surfaces of the pressing pieces 124 and 126 protruding from the side end surfaces of the guide members 114 and 116 on the free end side. The solenoids 128 and 129 are connected to the control unit 88 (see FIG. 5) of the paper processing system 12 and are driven according to instructions from the control unit 88.

  The guide member 114 (or the guide member 116) is urged upward by a biasing means (not shown), and when the solenoid 128 (or solenoid 129) is OFF, the guide member 114 (or guide). The member 116) is kept horizontal and guides the conveyed paper a (or paper b) horizontally.

  On the other hand, when the solenoid 128 (or the solenoid 129) is turned ON, the plunger 130 (or the plunger 131) moves upward, and the guide member 114 (or the guide member 116) around the shaft 122 by the biasing force of the biasing means. ) Of the free end is flipped up. As a result, the conveyed paper a (or paper b) is guided downward.

  Since some sheets may be bound, bound, or the like after being cut, these post-processing devices may be arranged on the downstream side of the paper processing device 10. Depending on whether the sheets are accommodated in the stacks 26 and 28, the transport path for the sheets a and b is selected. In some cases, the paper is once stored in the paper stack when the paper is conveyed to the post-processing apparatus.

  Further, although the solenoids 128 and 129 are used here, it is only necessary that the inclination of the guide members 114 and 116 can be changed. For example, although not shown, an eccentric cam may be used to change the inclination of the guide members 114 and 116 depending on the rotation angle of the eccentric cam.

  Next, the operation of the sheet processing apparatus 10 will be described.

  As shown in FIG. 1, the continuous paper P supplied from the continuous paper supply device 14 is conveyed to the paper buffer mechanism 16 and is conveyed to the paper processing device 10 while adjusting the tension applied to the continuous paper P. In the paper processing apparatus 10, the continuous paper P is cut into a desired paper size by the slitter unit 20 and the cutter unit 22 in accordance with the size of the continuous paper P to be conveyed.

  As shown in FIG. 4, when two continuous sheets A and B are obtained in the width direction of the conveyed continuous sheet P, if the lengths of the sheet a and the sheet b are the same, the full width of the continuous sheet P is increased. Although there is no problem if the paper is cut by the cutter unit 22, as shown in FIG. 8, when the lengths of the paper a and the paper b are different, the full width of the continuous paper P cannot be cut by the cutter unit 22.

  Therefore, in the embodiment of the present invention, the cutter unit 22 includes a plurality of cutting units 64 and 66 along the width direction of the continuous paper P, and drive motors 84 and 100 that drive the cutting units 64 and 66, respectively. Are provided individually, and the cutting portions 64 and 66 can be rotated in an independent state. And according to the instruction | indication from the control part 88 (refer FIG. 5), the drive motors 84 and 100 shown in FIG. 2 are each rotated by predetermined rotation speed, and the cutting | disconnection parts 64 and 66 are rotated individually.

  Thus, the continuous paper A is cut along the width direction by the cutting unit 64, and the continuous paper B is cut along the width direction by the cutting unit 66. In other words, the continuous sheets A and B are continuously cut by one cutting device even though the desired sheet sizes (sheets a and b) are different between the conveyed continuous sheets A and B.

  For example, there is a difference in the amount of information required for each customer, or different forms are processed together, such as paper setup of different sizes without complicated post-processing machines, etc. The continuous papers A and B can be changed to the desired paper sizes (papers a and b) while preventing wasteful consumption of the continuous papers A and B due to the deterioration of the total performance and the switching and setup of the continuous papers A and B. Can be cut continuously.

  The sheets a and b cut to a desired size are each conveyed to a sheet guide device 24 located on the downstream side of the cutter unit 22. In the sheet guiding device 24, the conveying paths of the sheets a and b to be conveyed are switched by the guide members 114 and 116 to guide the sheets a and b to the sheet stacks 26 and 28, respectively.

  In addition, the continuous paper A and B have substantially the same widthwise dimensions here, but the width of the continuous papers A and B can be changed as shown in FIG. In this case, although the position of the center slitter 36 is changed, the support body 44 provided with the shaft support plate 42 for supporting the center slitter 36 shown in FIG. 2 is moved.

  The control unit 88 (see FIG. 5) gives an instruction to rotate the stepping motor 110 by a predetermined angle. As a result, the stepping motor 110 rotates by a predetermined angle, and the support 44 moves along the width direction of the conveyed continuous paper P via the drive belt 104 and the connecting portion.

  Accordingly, in the cutter unit 22, the position of the boundary portion P between the cutting unit 64 and the cutting unit 66 is shifted, and the position of the center slitter 36 is shifted. Thus, by providing the center slitter 36 integrally with the support body 44, the position of the center slitter 36 and the position of the boundary portion P between the cutting portion 64 and the cutting portion 66 are always matched.

  Further, the position of the boundary portion Q between the guide member 114 and the guide member 116 is also adjusted to the position of the center slitter 36. Accordingly, the papers a and b cut by the cutter unit 22 can be reliably guided to the predetermined transport path by the guide members 114 and 116, and the paper jam where the paper a and the paper b overlap is suppressed. it can.

  Here, regarding the movement of the support 44, the unnecessary portion 56 is configured on the continuous paper P by an instruction from the control unit 88, and the support 44 is moved while the unnecessary portion 56 passes, There is no need to stop the sheet processing apparatus 10.

  By the way, as described above, the continuous paper P conveyed by an instruction from the control unit 88 is cut into a desired paper size by the slitter unit 20 and the cutter unit 22 and guided to a predetermined conveyance path. As shown in FIG. 9, barcodes (cutting instruction information) 132 indicating the cutting position of the continuous paper P are recorded in advance at both ends in the width direction of the continuous paper P being conveyed. Since the barcode 132 is recorded in an area corresponding to the unnecessary portion 56 shown in FIG. 4, the barcode 132 does not remain on the cut paper.

  As shown in FIG. 1, a line sensor that reads information on barcodes 140 and 141 (see FIGS. 10A and 10B) to be described later on the upstream side of the sheet processing apparatus 10 in the conveyance direction of the continuous paper P. Read sensors 134 and 136 are arranged.

  The reading sensors 134 and 136 (the reading sensor 134 is arranged on the front side of the drawing in FIG. 1 and the reading sensor 136 is arranged on the back side of the drawing) are connected to the control unit 88 as shown in FIG. The information read by the reading sensors 134 and 136 is input to the control unit 88.

  For example, in the barcode 132 shown in FIG. 9, “0-3-12.5” is recorded from the upstream side to the downstream side in the transport direction of the continuous paper P. Here, “0” is A block information, and “3” is B block information. “12.5” is C block information.

  That is, here, the cutting control information in the conveyance direction of the continuous paper P is (A-0), and the range from the designated end to 12.5 inches (C) is cut along the width direction of the continuous paper P. (B-3: cutting range by the cutter unit 22), which is information indicating the cutting position in the conveyance direction and the width direction of the continuous paper P.

  Here, no symbol is added after 12.5. However, when alphabets such as A, B, and C are added, this is information of the D block, and the paper transport destination (paper Stacks 26, 28, etc.) are shown. Further, purging means so-called disposal processing and is guided to a disposal paper storage box 58 (see FIG. 1).

  Here, in order to obtain a sheet of a predetermined size, a center slitter 36 (sometimes referred to as a “side slitter 34”) needs to be disposed at a position 12.5 inches from the designated end (hereinafter referred to as “predetermined position”). However, the boundary portion P between the cutting portion 64 and the cutting portion 66 of the cutter portion 22 also needs to be adjusted to the predetermined position.

  For this reason, the stepping motor 110 is driven by the controller 88, and the support 44 is moved along the width direction of the conveyed continuous paper P via the pulleys 106 and 108 and the drive belt 104 (FIG. 7A). (See (B)). Thereby, the cutting part 64 of the cutter part 22, the boundary part P of the cutting part 66, and the center slitter 36 are aligned at predetermined positions.

  In order to guide the cut sheets a and b to the stack 26 or 28, it is necessary to match the position of the boundary portion Q between the guide member 114 and the guide member 116 with the position of the center slitter 36. For this reason, it is necessary to drive the drive motors (moving means) 123 and 125, but the drive motors 123 and 125 are controlled by the control unit 88 based on the information (cutting position) of the cutting range by the cutter unit 22.

  Accordingly, the stepping motor 110 is driven and the cutter unit 22 and the center slitter 36 are aligned at predetermined positions, and the drive motors 123 and 125 are driven and the guide member 114 and the guide member 116 are aligned at predetermined positions.

  As described above, in the case of the barcode 132 as described above, cutting information is instructed in detail, and the barcode 132 is generally recorded for each sheet. In this embodiment, for example, FIG. As shown in (A) to (C), when the repetitive operation continues (the cutting position is the same), the barcodes 140 and 141 indicating the information of the cutting position are recorded at the start position and the end position of the repetitive operation. ing. Here, FIG. 10A shows a case where there is one center slitter 36, but FIG. 10B shows an example where two center slitters are used (not shown).

  Here, barcodes 140 and 141 are recorded on both ends in the width direction of the continuous paper P to be conveyed, and a mark (hereinafter referred to as a horizontal line) shown in FIG. The “start mark” instructs the start of the paper size change, and the mark with five horizontal lines drawn in the white corner (hereinafter referred to as the “end mark”) instructs the end of the paper size change. To do.

  Further, a mark (first cutting position mark; hereinafter referred to as “position mark”) in which one vertical line is drawn in a white corner is a cutting position (the position of the center slitter 36) at the end in the width direction of the conveyed continuous paper P. Alternatively, it indicates a cutting range by the cutter unit 22, and a black square mark (second cutting position mark; hereinafter referred to as “cutting mark”) indicates a cutting position (cutting timing).

  As shown in FIGS. 10A and 10B, when the same paper size continues along the conveyance direction of the continuous paper P, the upstream side from the downstream side in the conveyance direction of the continuous paper P before the paper size is changed. A start mark, a position mark, and a cutting mark are recorded in order, and only a cutting mark for performing a cutting instruction is recorded on each sheet until the next paper size is changed. . Then, before changing the paper size next time, an end mark and a position mark are recorded.

  Basically, the barcodes 140 and 141 are recorded on both ends in the width direction of the conveyed continuous paper P. As shown in FIG. 10A, the width direction of the continuous paper P is recorded. In the case of the sheets A and B having only different dimensions, the dimensions of the continuous paper P in the transport direction are the same between the paper A and the paper B, so the bar codes 140 and 141 are recorded only at one end in the width direction of the continuous paper P. May be.

  Here, the position mark recorded on the upstream side of the end mark does not necessarily need to be recorded because the paper size does not change from the start mark to the end mark, but the cutting start position and the cutting end position are not necessarily recorded. The occurrence of errors can be suppressed by checking whether or not the numerical values indicating the cutting positions at the edges in the width direction of the continuous paper P being conveyed are the same.

  As described above, when the repetitive operation continues, the barcodes 140 and 141 indicating the cut position are recorded at the start position and the end position of the repetitive operation, so that the waste of recording the cut position on the continuous paper P can be saved. .

  In addition, if the cutting instruction information is recorded on each of the sheets a and b and the cutting instruction information is individually read in spite of the repetition operation, if a reading error occurs, the error target sheet is specified. Difficult to do. However, in this embodiment, even if a reading error occurs, the error occurs in a predetermined area, and it is easy to specify the error target sheet.

  Here, when the paper size is changed, as described above, the stepping motor 110 is driven by the instruction from the control unit 88 so that the cutter unit 22 and the center slitter 36 are adjusted to predetermined positions, or the driving motors 123 and 125 are set. It is necessary to drive the guide member 114 and the guide member 116 to a predetermined position.

  On the other hand, after the end mark, until the next start mark, the cutting instruction is not given. This area is regarded as an unnecessary portion 57 and is discarded, but the movement of the cutter portion 22, the center slitter 36, the guide member 114, and the guide member 116 is ended while the unnecessary portion 57 passes through. .

  Further, the barcodes 140 and 141 have a square shape (including a straight line) along the width direction of the continuous paper P to be conveyed. However, as shown in FIG. A shape in which two trapezoidal marks 142A and 142B having different lengths at the positions in the direction are combined upside down may be included.

  Here, since the reading sensors 134 and 136 use line sensors, when the misregistration detection mark 142 is read, the misregistration detection mark 142 depends on the position in the width direction of the continuous paper P being conveyed. The length of the black part along the conveyance direction is different.

  For this reason, the misalignment detection mark 142 is used not only as a reference position in the transport direction of the continuous paper P but also as a reference position in the width direction of the continuous paper P with respect to the reference position in the width direction of the continuous paper P. The amount of misalignment can be calculated by the control unit 88. Then, by correcting the cutting position by the slitter unit 20 and the cutter unit 22 based on this positional deviation amount, it is possible to correct the positional deviation amount of the conveyed continuous paper P.

  On the other hand, when the cutter unit 22 is driven independently by the cutting unit 64 and the cutting unit 66, the cutting pitch can be changed between the cutting unit 64 and the cutting unit 66. For this reason, as shown in FIGS. 10A and 10B, the positions of the start and end of cutting of the center slitter 36 and the cutting section 64 (or cutting section 66) can be made coincident with each other. Thus, the so-called L-shaped control (P section) and horizontal T-shaped control (Q section) can be performed by making the cutting section 64 (or the cutting section 66) orthogonal.

[Second Embodiment]
Hereinafter, a sheet processing apparatus according to the second embodiment will be described. Note that a description of substantially the same contents as in the first embodiment will be omitted.

(Slitter part)
FIG. 12 is a schematic plan view of the sheet processing apparatus 150 according to the present embodiment. Here, the slitter unit 152 is provided with a substantially rectangular parallelepiped holding member 154 supported by a support body (not shown) constituting the sheet processing apparatus 150, and the width direction of the conveyed continuous paper P is provided. Are arranged obliquely (arrangement angle: θ).

  The holding member 154 is provided with laser cutters 156, 158, and 160 that emit laser light in the same straight line along the longitudinal direction of the holding member 154, and each has a predetermined length along the longitudinal direction of the holding member 154. Sliding movement (reciprocating movement) is possible within the section. The continuous paper P to be conveyed is cut by the laser beams of the laser cutters 156, 158, and 160.

  The laser cutters 156, 158, and 160 are slidable by driving means such as linear motors 161, 162, and 163 connected to the control unit 155 shown in FIG. 13, and slide along the longitudinal direction of the holding member 154. By moving, it is skewed along the width direction of the continuous paper P being conveyed.

  Here, since each laser cutter 156, 158, 160 cuts the continuous paper P along the conveyance direction of the continuous paper P, the linear motors 161, 162, 163 slide when the continuous paper P is cut. Are stopped, and laser beams are emitted from the laser cutters 156, 158, and 160, respectively.

  Here, the holding member 154 is disposed obliquely with respect to the width direction of the continuous paper P to be conveyed. However, the laser cutters 156, 158, and 160 provided on the holding member 154 cut the continuous paper P. The holding member 154 may be disposed along the width direction of the conveyed continuous paper P because it does not slide.

(Cutter part)
As shown in FIG. 12, the cutter unit 153 has a substantially rectangular parallelepiped holding member 164 disposed obliquely (arrangement angle: θ) with respect to the width direction of the conveyed continuous paper P, similarly to the slitter unit 152. Is provided. The holding member 164 is provided with a laser cutter 166, and can be slid (reciprocated) by a driving means such as a linear motor 168 connected to the control unit 155 (see FIG. 13).

  The laser cutter 166 is slid along the longitudinal direction of the holding member 154 (reciprocating), so that the laser cutter 166 is skewed along the width direction of the conveyed continuous paper P. In order to cut the continuous paper P along the width direction of the continuous paper P by the laser cutter 166, the continuous paper P is cut by emitting laser light while sliding the laser cutter 166 by the linear motor 168.

Here, the linear motor 168 reads the information by the barcodes 140 and 141 of the continuous paper P conveyed by the reading sensors 134 and 136 and then, in the control unit 155, the conveyance speed (V _P ), the arrangement angle (θ) of the holding member 154, and the cutting range of the laser cutter 166 (H: (0 ≦ H ≦ full width dimension of the continuous paper P)), the moving speed (V _C ) of the laser cutter 166 is calculated. The laser cutter 166 is moved. Here, the holding member 154 can change the arrangement angle, and the arrangement angle can be changed according to the conveyance speed of the continuous paper P.

  14 and 15 show the operation of each laser cutter 156, 158, 158, 166. FIG. A solid line indicates a state in which laser light is emitted, and a wavy line indicates a state in which laser light is not emitted. As shown in FIGS. 12 and 14, when obtaining sheets a, b, c, d, and e having different sizes (note that sheets d and e are so-called unnecessary portions), as shown in FIGS. The laser cutters 156, 158, and 160 emit laser light at the same position (solid line), and cut the continuous paper P that is conveyed (cut lines A, B, and C).

  On the other hand, the laser cutter 166 emits laser light while moving from point D to point E, and cuts the cut continuous paper along the width direction. The laser cutter 166 does not emit laser light from point E to point F. When reaching the point F, the laser cutter 166 emits laser light while moving until reaching point G. As a result, the sheet a is cut. Next, the laser cutter 166 does not emit laser light from point G to point H, and when it reaches point H, it emits laser light while moving until it reaches point I. Thereby, the unnecessary part d, the paper b, the paper c, and the unnecessary part e are cut.

  Here, only one laser cutter 166 for cutting the width direction of the continuous paper P to be conveyed is used, but a plurality of laser cutters 166 may be used. In this case, a plurality of laser cutters may be arranged on one holding member 164 so as to be movable in parallel, or a holding member may be provided for each laser cutter.

  It is needless to say that the above embodiment is merely an example, and can be appropriately changed without departing from the gist of the present invention.
