  2. Description of the Related Art Conventionally, a processing apparatus that processes a conveyed sheet with a processing member is known. Japanese Patent Application Laid-Open No. 2004-228561 describes a technique for cutting a sheet with a pair of cutter blades that are spaced apart from each other via a sheet conveyance path. The upper cutter blade is inclined with respect to the lower cutter blade, and a sensor is formed at one end of the upper cutter blade to form a gap through which the sheet can pass between the lower cutter blade and the lower cutter blade. When detected, the conveyance of the sheet is resumed.

Japanese Patent No. 5536505

In Patent Document 1, the conveyance of the sheet is resumed until the upper cutter blade reaches the upper limit position. Thus, the time required for sheet processing can be shortened. However, since the conveyance of the sheet is resumed at the same timing both when the sheet size is large and when the sheet size is small, the sheet cannot be processed efficiently.

  The objective of this invention is providing the processing apparatus which can perform the processing of a sheet | seat more efficiently.

  In order to solve the above problems, the processing apparatus of the present invention is provided with a transport unit that transports a sheet, a processing member that processes the sheet transported by the transport unit, and a moving unit that moves the processing member. A processing unit, and a control unit configured to stop the conveyance by the conveyance unit and control the sheet conveyance process to be resumed after the sheet is processed by moving the processing member by the moving unit. Based on the size, at least one of a timing at which the conveyance of the sheet is resumed by the conveyance unit and a movement of the processing member when the sheet is conveyed to the installation position of the processing member by the moving unit is controlled.

Further, in the above configuration, the control unit is configured to reduce the time required for sheet processing when the length is shorter than when the length in the crossing direction intersecting the sheet transporting direction is long. Control at least one of the following.

In each of the above configurations, the processing member includes a pair of processing molds that sandwich and process the sheet, and the moving unit includes an contacting / separating unit that moves the pair of processing molds in the contacting / separating direction, The control unit controls the contact / separation unit to separate the pair of processing dies after the sheet is sandwiched and processed by the pair of processing dies.

Further, in each configuration, the control unit controls at least one of the conveying unit and the moving unit based on whether a distance between the pair of processing dies is equal to or greater than a predetermined value that can pass through the sheet.

Further, in each of the above configurations, the pair of processing dies are arranged so as to face each other via a sheet conveying surface and extend along a crossing direction intersecting the sheet conveying direction, and the control unit is configured to process the sheet Before and after the processing, the timing at which the pair of processing dies are brought into contact with and separated from each other in the intersecting direction, and the conveyance position in the width direction orthogonal to the sheet conveyance direction is set at a location where the timing at which the pair of processing dies are separated from each other is early Control is performed so that the sheet is conveyed with priority over the later part.

Further, in each of the above-described configurations, the moving unit moves the processing member in the intersecting direction that intersects the sheet conveyance direction.

Further, in each of the above configurations, a slitter processing unit that cuts the sheet along the transport direction is provided at a position upstream of the processing unit in the transport direction of the sheet by the transport unit.

According to the present invention, the control unit determines the timing of resuming the conveyance of the sheet by the conveyance unit and the movement of the processing member when the sheet is conveyed to the installation position of the processing member by the moving unit based on the size of the sheet. Since at least one of them is controlled, the sheet can be conveyed or the processing member can be moved at a timing suitable for the size of the sheet, and the processing time of the sheet can be shortened.

In addition, the control unit is configured to reduce at least one of the conveyance unit and the movement unit so that the time required for the sheet processing process is shortened when the length in the crossing direction intersecting the sheet conveyance direction is long. In the case of controlling the sheet, the sheet processing efficiency can be improved.

Furthermore, the control unit controls between at least one of the conveying unit and the moving unit based on whether the distance between the pair of processing dies is equal to or greater than a predetermined value that can pass through the sheet. In this case, the sheet can be processed more efficiently as compared with the case where the sheet is conveyed while the distance is set to a certain amount or more regardless of the size of the sheet.

Further, the pair of processing dies are arranged so as to face each other via a sheet conveying surface and extend along a crossing direction intersecting a sheet conveying direction, and the control unit is arranged before and after the sheet processing process, The timing of contacting and separating the pair of processing dies is different in the intersecting direction, and the feeding position in the width direction orthogonal to the sheet feeding direction is given priority over a location where the timing of separating the pair of processing dies is earlier than a later location. When controlling to convey the sheet, the processing time when the size of the sheet is small can be made shorter than when the sheet is large.

Furthermore, when the moving member moves the processing member in the crossing direction that intersects the sheet transporting direction, it resumes sheet transport when the processing member is out of the sheet transporting range, or is processed near the edge of the sheet. The member can be positioned and waited.

When a slitter processing unit for cutting the sheet along the transport direction is provided at a position upstream of the processing unit by the transport unit in the sheet transport direction, the processing unit is configured to process the sheet by the slitter processing unit. If the length in the crossing direction of the sheet leading to is shorter than that before the processing, the processing can be performed more efficiently.

Form.

[Cutter Mechanism 22] The cutter mechanism 22 constitutes a processing unit. The processing unit is provided with a processing member 51 that processes the sheet S conveyed by the conveyance unit 4 and a moving unit 54 that moves the processing member 51. The processing member 51 includes a pair of processing dies 52 that sandwich and process the sheet S. The pair of processing dies 52 are disposed to face each other with the conveyance surface of the sheet S interposed therebetween. The processing die 52 in the cutter mechanism 22 is constituted by a pair of cutting blades 55. The pair of cutting blades 55 can be constituted by, for example, an upper blade 57 and a lower blade 58.

FIG. 2 shows a specific example of the cutter mechanism 22. In the figure, the cutter mechanism 22 is viewed from the downstream side in the conveyance direction of the sheet S. The pair of processing dies 52 are arranged so as to face each other via the conveyance surface 6 of the sheet S and extend along a crossing direction intersecting the conveyance direction F of the sheet S. In particular, the upper blade 57 and the lower blade 58 as the pair of processing dies 52 according to the present embodiment are configured to extend along the width direction W orthogonal to the conveyance direction F of the sheet S.

The upper blade 57 is inclined with respect to a horizontal plane so that the left side is high and the right side is low in the drawing. The upper blade 57 is configured as a movable blade that can be moved by the moving unit 54. The lower blade 58 faces the upper blade 57 and is disposed substantially horizontally so as to extend in the width direction W. The lower blade 58 is configured as a fixed blade fixed to the lower blade base 59.

The pair of parallel link mechanisms 64 are provided on both sides of the upper blade 57 in the width direction W, respectively. The parallel link mechanism 64 oscillates about the two oscillating shaft centers 641 and 642 as axes.

The upper end portion of the arm 65 is connected to the end portion of the upper blade 57 shown on the right side in FIG. The lower end of the arm 65 is connected to the disc surface of the crank gear 67. The crank gear 67 is connected to a contact / separation drive unit 70 such as a motor via a power transmission mechanism 68 including a plurality of gears and a belt.

When the contact / separation drive unit 70 is driven, the crank gear 67 rotates through the power transmission mechanism 68 and moves the upper end of the arm 65 so as to draw a substantially elliptical orbit. Accordingly, the right end portion of the upper blade 57 in FIG. 2 is moved so as to draw a substantially elliptical orbit. The upper blade 57 is swung in the vertical direction while maintaining the inclined posture, and is in contact with and separated from the lower blade 58. When the upper blade 57 descends, the blade edge 571 of the upper blade 57 sequentially contacts the blade edge 581 of the lower blade 58 in the width direction W from the right end portion to the left end portion, and the sheet S between the upper blade 57 and the lower blade 58 is moved. Cut in the width direction W sequentially from the right end portion to the left end portion along the width direction W.

Then, after the cutting process of the sheet S, the upper blade 57 is moved upward while maintaining the inclined posture and separated from the lower blade 58. At this time, the blade edge 571 of the upper blade 57 is gradually expanded in the width direction W from the left end portion to the right end portion in the non-contact manner with respect to the blade edge 581 of the lower blade 58 contrary to the descending state. As described above, the upper blade 57 and the lower blade 58 as the pair of processing dies 52 are installed so that the timing of contacting and separating the pair of processing dies 52 before and after the processing of the sheet S is different in the crossing direction. ing.

The position detection unit 72 detects the position of the upper blade 57. The position detection unit 72 includes two optical sensors 721 and 722 and a light shielding plate 723. The detection result of the position detection unit 72 is transmitted to the control unit 45.

[Sheet processed product arrangement pattern]
FIG. 3 is a plan view showing an example of the processing pattern of the sheet S. FIG. In the processing pattern shown in the figure, a plurality of processed products Q are manufactured from one sheet S1. A plurality of cutting lines T1 to T4 extending in parallel with the transport direction F and a plurality of cutting lines K1 to K10 extending in the width direction W are set. A plurality of cutting lines K1 to K10 extending in the width direction W are used to process the sheet S1 by moving the upper blade 57 as the processing member 51 in the contact / separation direction with respect to the lower blade 58 by the contact / separation portion 61 as the moving portion 54. The processing line obtained in this way is configured.

The first and fourth cutting lines T1 and T4 shown at the right end and the left end in FIG. 3 can be formed by the pair of rotary blades 36 in which the upper blade 361 and the lower blade 362 are installed in the slitter mechanism 20 one by one. The second and third cutting lines T2 and T3 formed between the first cutting line T1 and the fourth cutting line T4 use a rotary blade pair 36 in which one upper blade 361 and one lower blade 362 are installed, or The blade edge of either the upper blade 361 or the lower blade 362 can be formed using a rotating blade pair 36 in which the other blade edge contacts from both sides.

Further, the cutting line K along the width direction W indicates that the sheet S1 has a cutting line T in the slitter mechanism 20 installed at the upstream side in the conveyance direction F of the sheet S1 by the conveyance unit 4 from the cutter mechanism 22 as the processing unit. After cutting along the conveying direction F, the long chips J cut out from the sheet S1 are removed, so that a plurality of belt-like strips are arranged and separated by a predetermined amount in the width direction W. The sheet Sw is formed by being simultaneously cut.

In the processing pattern of the sheet S1 shown in FIG. 3, the fold line by the fold line forming mechanism 21 is not set. Therefore, in the processing apparatus 100 illustrated in FIG. 1, the fold line forming mechanism 21 is received by the receiving portion 29. The fold line forming process is not performed, the fold line forming process is not performed, or a conveyance processing mechanism (not shown) is replaced, or the fold line forming mechanism 21 is detached and used in an empty state.

[Control Unit 45] The control unit 45 incorporates a program for processing the sheet S. FIG. 4 shows a control flow when the sheet S is processed. In step 101 of FIG. 4, the processing information of the sheet S is acquired. In step 102, a preparation operation for processing the sheet S is performed. In step 103, the processing operation of the sheet S is executed.

Further, the following program is incorporated in the control unit 45 with respect to processing in the cutter mechanism 22. The control unit 45 stops the conveyance of the sheet S by the conveyance unit 4 in the cutter mechanism 22 as the processing unit, moves the upper blade 57 as the processing member 51 by the moving unit 54, and moves the lower blade 58 through the sheet S. After the sheet S is processed, the conveyance unit 4 controls to resume conveyance of the sheet S. At that time, the control unit 45 controls the timing for resuming the conveyance of the sheet S by the conveyance unit 4 based on the size of the sheet S.

Further, the control unit 45 controls the conveyance unit 4 so that the time required for the sheet S processing is shortened when the length in the crossing direction that intersects the conveyance direction F of the sheet S is long. It is good. The control unit 45 may control the contact / separation unit 61 so as to separate the pair of processing dies 52 after the sheet S is sandwiched and processed by the pair of processing dies 52. Further, the control unit 45 may control the conveyance unit 4 based on whether or not the distance between the pair of processing dies 51 is equal to or greater than a predetermined value that can pass through the sheet S. Further, the control unit 4 varies the timing of contacting and separating the pair of processing dies 52 before and after the processing of the sheet S in the intersecting direction, and sets the transport position in the width direction W orthogonal to the transport direction F of the sheet S. The sheet S may be controlled so that the position where the pair of processing dies 52 are separated is given priority over the position where the timing is late.

The control unit 45 has a length Lw in the width direction W of the sheet S and a length Lj in the width direction W of the chip Ja at the right end of the sheet S that is cut out by the slitter mechanism 20 and discharged downward from the conveyance path 5. A length Lx from the reference position B of the sheet S that passes between the pair of processing dies 52 of the cutter mechanism 22 as the processing unit is calculated based on the information on the size of S and the processing. Then, the length Lx from the calculated reference position B is referred to a table stored in advance in the storage device, so that the sheet is processed after the processing along the width direction W in the cutter mechanism 22 as a processing unit. The timing for resuming the conveyance of S is acquired.

Table 1 below is an example of a table relating to the timing at which the conveyance of the sheet S stored in advance in the storage device is resumed.

In Table 1, the length from the reference position means that the sheet S is conveyed along one side edge of the sheet S on the side wall 18 erected on the conveying path 5, and the processing is executed by each processing mechanism. When the sheet S is conveyed up to 22, it means the length from the side wall 18 as the reference position B to the other side edge of the sheet S on the conveyance path 5. In the processing pattern shown in FIG. 3, the left edge SL of the sheet S corresponds to the reference position B. In the slitter mechanism 20, when the sheet S is cut by the first to fourth cutting lines T1 to T4 and unnecessary chips J are removed, the length Lx from the reference position B of the sheet S reaching the cutter mechanism 22 is processed. This is the length Lx from the left edge SL of the sheet S before processing to the fourth cutting line T4.

As described above, when the slitter mechanism 20 for cutting the sheet S along the transport direction F is provided at the upstream side in the transport direction F of the sheet S by the transport unit 4 from the cutter mechanism 22 as the processing unit, the reference The length Lx from the position B may be shorter than the length Lw in the width direction W of the sheet S before processing. The length Lj in the width direction W of the chip Ja set on the other side edge SR side facing the reference position B of the sheet S is subtracted from the length Lw in the width direction W of the sheet S before processing. The length is the length Lx from the reference position B.

The waiting time shown in Table 1 is a waiting time until the conveyance of the sheet S is resumed after the sheet S is processed. In the cutter mechanism 22, the upper blade 57 descends to reach the lower limit position, and the cutting process in the width direction W of the sheet S is completed. Thereafter, the upper blade 57 blocking the conveyance path 5 is raised by the contact / separation portion 61 until the distance between the upper blade 57 and the lower blade 58 reaches a predetermined length through which the sheet S after cutting can pass. Then, the conveyance unit 4 waits for the conveyance of the sheet S to resume. The waiting time is the waiting time described in Table 1.

The fact that the upper blade 57 is in the lower limit position means that the control unit 45 starts driving the contact / separation driving unit 70 in a state where the upper blade 57 is in the upper limit position, and measures the elapsed time to calculate this elapsed time. It can be judged on the basis. Further, it may be detected using the lower limit sensor 722 that the upper blade 57 is in the lower limit position. When the upper blade 57 is at the lower limit position, the light shielding plate 723 is detached from the lower limit sensor 722. The control unit 45 can use the time when the lower limit sensor 722 changes between light transmission and light shielding as the time when the upper blade 57 reaches the lower limit position and the processing is completed.

Regarding the standby time exemplified in Table 1, when the length of the sheet S from the reference position B is less than 200 mm, the standby time is set to 30 msec. In this case, the control unit 45 cuts the sheet S and drives at least the transport drive units 43 and 44 before and after the cutter mechanism 22 when 30 msec has elapsed from the time when it is detected that the upper blade 57 has reached the lower limit position. Then, the conveyance of the sheet S is resumed. At this time, the conveyance driving units 41 and 42 that rotate the conveyance rollers 9 and 10 installed on the upstream side of the cutter mechanism 22 are configured to convey the conveyance roller pairs 11, 12, and 13 that rotate before and after the cutter mechanism 22. Driving may be started at the same timing as the driving units 43 and 44, or may be activated or stopped at different timings.

In Table 1, when the length of the sheet S from the reference position B is 200 mm or more and less than 300 mm, the standby time after the processing is set to 40 msec. In this case, the control unit 45 resumes driving of the conveyance driving units 43 and 44 after 40 msec has elapsed from the processing time longer than when the length of the sheet S from the reference position B is less than 200 mm.

When the length of the sheet S from the reference position B is 300 mm or more, the standby time after the processing is set to 50 msec. Therefore, the control unit 45 resumes driving of the transport driving units 43 and 44 after 50 msec has elapsed from the processing time.

FIG. 5 shows a control flow when executing a cutting process as a processing process in the cutter mechanism 22 as a processing unit. In step 11 of FIG. 11, the control unit 45 conveys the sheet S by the conveyance unit 4 to the processing unit. In step 12, when the processing position of the sheet S reaches between the processing dies 52, the control unit 45 stops the conveyance of the sheet S. In step 13, the control unit 45 starts a machining operation.

In step 14, the control unit 45 determines whether or not it has been detected that the machining die 52 has reached the lower limit position. Step 14 is continued until step 14 is satisfied. When the control unit 45 detects that the machining die 52 has reached the lower limit position, step 14 is satisfied and the process proceeds to step 15. In step 15, measurement of the standby time for resuming the conveyance of the sheet S is started. When the standby time at which measurement is started in step 15 reaches a predetermined standby time corresponding to the length Lx from the reference position B shown in Table 1, step 16 is satisfied and the routine proceeds to step 17. In step 17, the control unit 45 resumes the conveyance of the sheet S.

In step 18, it is determined whether it is detected that the machining die 52 has reached the upper limit position. When it is detected that the upper blade 57 has reached the upper limit position, Step 18 is satisfied, and the process proceeds to Step 19 where the control unit 45 stops the movement of the upper blade 57.

In step 20, the control unit 45 determines whether or not the next processing position to be processed by the processing unit is set. If the next machining position is set, the process returns to step 12. When the next processing position is not set, the process proceeds to step 21 where the control unit 45 stops the conveyance of the sheet S at a predetermined timing when the sheet S reaches the paper receiving unit 2.

Next, the operation of the processing apparatus 100 will be described. In step 101 of FIG. 4, the control unit 45 acquires processing information of the sheet S. The processing information is acquired from the operation panel 46 shown in FIG. 1 when the user inputs various work setting information regarding the size and type of the sheet S, the arrangement, number and dimensions of the processed product Q, the processing line formation position, and the like. Is done. Instead of this manual input or in cooperation with the manual input, various work setting information including the processing information of the sheet S may be automatically input by reading the barcode M2 or the like by the reading means 26. it can. Further, the processing information of the sheet S can be acquired by calling the work setting information stored in the storage device.

The control unit 45 calculates the amount of movement of each rotary blade pair 36 from the home position in the width direction W from information regarding the cutting position along the conveyance direction F among the acquired processing information of the sheet S. Further, the conveyance amount by the conveyance unit 4 from the front edge Sa of the sheet S to each processing line K is calculated from the information regarding the cutting position along the width direction W in the cutter mechanism 22.

Further, the control unit 45 corresponds to the processing information of the sheet S, in particular, the length Lw in the width direction W of the sheet S and the side edge of the sheet S farthest from the reference position B on the conveyance path 5 in FIG. The length Lx from the reference position B of the sheet S passing between the upper blade 57 and the lower blade 58 of the cutter mechanism 22 is calculated from the information regarding the cutting position indicated by the fourth cutting line T4. And the control part 45 refers to the table memorize | stored in the memory | storage device, The conveyance restart by the conveyance part 4 after cutting along the width direction W with the upper blade 57 and the lower blade 58 as the process type | mold 52 is restarted. Get the timing.

Next, in step 102 in FIG. 4, a preparation operation for processing the sheet S is performed. For this reason, in the paper feed unit 3, the lifting / lowering means is driven to move the paper feed table 31 to the paper feed position to the conveyance path 5 of the sheet S. Then, the blower 34 is driven and the sheets S are rolled one by one by the air flow. In the slitter mechanism 20, the rotary blade pair 36 is temporarily moved to the home position. Based on the processing information acquired in step 101, the sheet is moved by a predetermined amount in the width direction W to the cutting position. In the cutter mechanism 22, the contact / separation drive unit 70 is driven so as to move the upper blade 57 to the upper limit position. Accordingly, both the upper limit sensor 721 and the lower limit sensor 722 shown in FIG. 2 are in a state where light from the light emitting element is blocked by the light shielding plate 723. In the transport unit 4, excitation of the transport drive units 41 to 44 is started.

Then, in step 103 in FIG. 4, the processing operation for the sheet S is executed. At that time, first, a plurality of sheets S stacked on the sheet feeding table 31 of the sheet feeding unit 3 in FIG. 1 are fed one by one from the uppermost sheet S by the suction conveyance belt mechanism 32 and the sheet feeding roller pair 33. Supplied to the transport path 5.

The reading unit 26 reads the position mark M1 of the sheet S and the barcode M2 as necessary, and acquires various work setting information including processing information to be applied to the sheet S.

In the reject mechanism 25, if reading by the reading unit 26 is impossible and the processing conditions are unknown, the reject mechanism 25 operates on the sheet S, drops the unreadable sheet S, and collects it in the collection tray 38. to recover.

In the slitter mechanism 20, the sheet S is cut along a plurality of cutting lines T parallel to the transport direction F.

In the chip dropping mechanism 27, the chip J generated by being cut by the slitter mechanism 20 is dropped to the chip box 23.

In the fold line forming mechanism 21, according to the processing information of the sheet S, when a fold line in the width direction W is set, the convex portion of the upper mold 211 is inserted into the concave groove of the lower mold 212 and the fold line along the width direction W is set. Is formed.

In the cutter mechanism 22, the conveyance of the sheet S is stopped at the cutting line K forming position along the width direction W, and the sheet S is cut by the pair of processing members.

  FIG. 6 is a schematic diagram for explaining the operation of the processing for forming the cutting line K along the width direction W in the cutter mechanism 22. FIG. 2A shows a state before the sheet S is cut. Prior to cutting, the upper blade 57 is located at the upper limit position. When the upper blade 57 is in the upper limit position, both the upper limit sensor 721 and the lower limit sensor 722 have the light shielding plate 723 positioned between the light emitting element and the light receiving element, and both are shielded from light.

 When the cutting line K forming position of the sheet S reaches between the upper blade 57 and the lower blade 58 in step 12 in FIG. 5, the control unit 45 stops the conveyance of the sheet S by the conveyance unit 4. In step 13, the control unit 45 drives the contact / separation driving unit 70, moves the upper blade 57 from the upper limit position to the lower limit position, and starts a processing operation. When the contact / separation driving unit 70 starts driving, the crank gear 67 is rotated by a predetermined amount clockwise in FIG. 6 through the power transmission mechanism 68 as shown in FIG. 6B. As the crank gear 67 rotates, the connecting portion of the arm 65 to the crank gear 67 is moved to the right in FIG. The upper blade 57 descends in conjunction with the movement of the arm 65. At this time, the upper blade 57 is lowered by the left and right parallel link mechanisms 64 while tilting slightly to the right in FIG. 6B with the pivot shafts 641 and 642 as the shaft centers.

Due to the lowering of the upper blade 57, the blade edge of the upper blade 57 is brought into sliding contact with the blade edge of the lower blade 58 sequentially from the right end in FIG. The sheet S on the lower blade 58 is sequentially cut from the right end to the left end in FIG. 6 by contact with the lower blade 58 of the upper blade 57. The light shielding plate 723 descends in conjunction with the movement of the arm 65 while drawing an arc counterclockwise in FIG. 6 with the upper swing axis 641 as the axis. While the upper blade 57 reaches the lower limit position from the upper limit position, the light shielding plate 723 is separated from the upper limit sensor 721 and allows the upper limit sensor 721 to pass through.

In the stage shown in FIG. 6B, the upper limit sensor 721 is light-transmitting and the lower limit sensor 722 is light-shielding. Thereafter, the state that the upper limit sensor 721 transmits light and the lower limit sensor 722 blocks light is continued for a predetermined time until the upper blade 57 reaches the lower limit position.

FIG. 6C shows a state where the upper blade 57 has reached the lower limit position. At this time, the upper blade 57 and the lower blade 58 are in contact with each other in the entire range in the width direction W, and the sheet S is cut in the entire range in the width direction W. In a state where the upper blade 57 is at the lower limit position, the light shielding plate 723 is detached from both the upper limit sensor 721 and the lower limit sensor 722, and both sensors are light-transmitting. In step 14 of FIG. 5, the detection that the upper blade 57 has reached the lower limit position can be made when the lower limit sensor 722 changes from light blocking to light passing.

In step 14 of FIG. 5, when detecting that the upper blade 57 has reached the lower limit position, the control unit 45 can use the time point when the lower limit sensor 722 becomes light-transmitted from light shielding. When it is detected that the upper blade 57 has reached the lower limit position, the process proceeds to step 15 and measurement of the standby time for resuming the conveyance of the sheet S is started.

When the control unit 45 continues to drive the contact / separation drive unit 70 after the lower limit sensor 722 has passed light, the crank gear 67 further rotates clockwise in FIG. 6 and the upper blade 57 starts to rise. As the upper blade 57 rises, the light shielding plate 723 swings clockwise in FIG. And the front-end | tip part of the light shielding plate 723 reaches the installation position of the lower limit sensor 722, and changes the lower limit sensor 722 from light to light shielding. The control unit 45 can determine that the upper blade 57 has started to rise when the lower limit sensor 722 changes from light passing to light blocking.

As described above, the control unit 45 may detect that the upper blade 57 of Step 14 in FIG. 5 has reached the lower limit position when the lower limit sensor 722 changes from light shielding to light shielding. Instead, the lower limit sensor 722 may be blocked from light passing. By using the time when the lower limit sensor 722 is blocked from light passing after the upper blade 57 starts to rise is used to determine whether or not the upper blade 57 has reached the lower limit position in step 14, the conveyance of the sheet S is resumed. The waiting time to be measured can be shortened. As a result, when the upper blade 57 moves, the rotational speed of the motors constituting the contact / separation drive unit 70 varies among the individual motors, so that the amount of movement of the upper blade 57 varies, and the upper blade 57 of the upper blade 57 at the time when the conveyance is resumed The amount of displacement can be reduced. The conveyance of the processed sheet S can be resumed at a more accurate timing.

FIG. 6D shows a state between the upper blade 57 starting from the lower limit position and reaching the upper limit position. When the upper blade 57 reaches the upper limit position from the lower limit position, the upper blade 57 is sequentially separated from the lower blade 58 from the left end to the right end in FIG. During this time, the upper limit sensor 721 continues to pass light and the lower limit sensor 722 is shielded from light for a predetermined time.

When the standby time at which measurement is started in step 15 in FIG. 5 reaches a predetermined standby time corresponding to the length Lx from the reference position B shown in Table 1, step 16 is satisfied and the routine proceeds to step 17. In step 17, the control unit 45 drives the conveyance unit 4 to resume conveyance of the sheet S.

In the present embodiment, the upper blade 57 is inclined at a predetermined angle with respect to the horizontal direction, and the distance between the upper blade 57 and the lower blade 58 as the pair of processing dies 52 is in the conveyance direction F of the sheet S. It differs in the width direction W as the intersecting direction. Then, the upper blade 57 comes in contact with and separates from the lower blade 58 as the upper blade 57 moves up and down. When the upper blade 57 rises, the blade edge of the upper blade 57 is sequentially separated from the blade edge of the lower blade 58 from the left end portion to the right end portion in FIG. The timing at which the upper blade 57 and the lower blade 58 as the pair of processing dies 52 are separated after the processing of the sheet S by the control unit 45 driving the contact / separation driving unit 70 is the width direction W as an intersecting direction. Will be different. In FIG. 6, the left end portion of the upper blade 57 is separated from the lower blade 58 earlier than the right end portion.

The control unit 45 conveys the sheet S along the side wall 18 installed in the vicinity of the left end position of the upper and lower processing molds 52. The contact surface of the side wall 18 with the sheet S is a reference position B for conveying the sheet S. Even when the length Lw in the width direction W is different, the sheet S is conveyed at a position where the left edge SL of the unprocessed sheet S contacts the side wall 18. When the length of the sheet S in the width direction W is short, the sheet S is conveyed at a position biased to the left in FIG. 6 of the upper and lower processing dies 52 closer to the reference position B than when the sheet S is long.

FIG. 7 is an explanatory diagram when the sheets S2 and S3 having different lengths in the width direction W are conveyed in the cutter mechanism 22. FIG. FIG. 4A shows a sheet S2 having a long length L2 in the width direction W of the sheet S2, and FIG. 4B shows a short sheet S3. In the case of FIG. 2A, the length L2 of the sheet S2 in the width direction W extends to the vicinity of both ends of the processing mold 52 over substantially the entire length of the processing mold 52 in the width direction W. The conveyance position of the sheet S <b> 2 is a position where the left edge SL contacts the side wall 18.

As shown in FIG. 6A, when the length L2 of the sheet S2 in the width direction W is long, the upper blade 57 is sufficient to allow the sheet S2 to pass between the upper blade 57 and the lower blade 58. When it rises. Therefore, the control unit 45 needs to restart the conveyance of the sheet S2 when the upper blade 57 reaches the upper limit position or a position in the vicinity thereof.

As shown in FIG. 7, when the blade edge of the upper blade 57 is inclined with respect to the conveyance surface of the sheet S, in order for the sheet S <b> 2 to pass between the upper blade 57 and the lower blade 58, FIG. 7, the distance D <b> 2 between the upper blade 57 and the lower blade 58 needs to be equal to or greater than a predetermined value longer than the thickness of the sheet S.

On the other hand, in FIG. 7B, the length L3 of the sheet S3 in the width direction W is shorter than the sheet S2 of FIG. Even in this case (B), the conveyance position in the width direction W of the sheet S3 is a position where the left edge SL contacts the side wall 18. Since the length L3 of the sheet S3 is short, the conveyance position of the sheet S3 is not the center position in the width direction W of the processing die 52 but a position biased to the left in FIG.

In FIG. 7B, the timing at which the conveyance of the sheet S3 is resumed after the processing is during the ascending of the upper blade 57, and the distance D3 between the central portions in the width direction W of the upper blade 57 and the lower blade 58 is It can be set when it becomes more than the predetermined value which can pass S3. The length L3 of the sheet S3 in the width direction W is shorter than the length of the processing die 52. The sheet S does not reach the right end portion of the processing die 52 but only reaches the central portion of the processing die 52. Therefore, if the central portions of both the upper blade 57 and the lower blade 58 are separated by a distance D3 that can pass through the sheet S3, the conveyance of the sheet S can be resumed. The sheet S can be resumed before the upper blade 57 is completely moved upward and reaches the upper limit position.

Then, as shown in FIG. 7B, the right end portion of the upper blade 57 at the time of resuming the conveyance may not be separated from the lower blade 58 and may remain in contact. Even if a part of the upper blade 57 is in contact with the lower blade 58, the distance D3 between the upper blade 57 and the lower blade 58 is the sheet S3 on the left side, which is the range in which the sheet S3 passes in the width direction W. It is sufficient that the value is equal to or greater than a predetermined value that can be passed. In this case, the sheet S3 is properly conveyed without being obstructed by the upper blade 57 in the downstream conveyance.

Regarding the conveyance position of the sheet S in the width direction W, the control unit 45 gives priority to the left end portion in FIGS. 6 and 7 where the upper blade 57 as the pair of processing dies 52 is separated from the lower blade 58 earlier than the slower right end portion. By transporting the sheet S, the time required for processing the sheet S can be shortened.

Conventionally, regardless of the size of the sheet, the conveyance of the sheet is resumed when the distance between the upper blade and the lower blade reaches a predetermined value or more through which the sheet can pass as a whole. In this embodiment, since the timing at which the conveyance of the sheet S is resumed is controlled according to the size of the sheet S, the sheet S3 having a short length L3 in the width direction W as shown in FIG. 7B is processed. In this case, the conveyance can be resumed earlier than before, and the processing time can be shortened.

Further, when the sheet S is cut along the conveyance direction F by the slitter mechanism 20 installed on the upstream side in the conveyance direction F and unnecessary chips J are removed, the sheet on the conveyance path 5 leading to the cutter mechanism 22 is obtained. The length Lx from the reference position B of S may be shorter than the length Lw in the width direction W of the sheet S before processing. As described above, the control unit 45 controls the timing of resuming the conveyance after the processing by the cutter mechanism 22 according to the processing state of the sheet S. Therefore, when the right end of the upper blade is separated from the lower blade by a gap that allows passage of the maximum length Lw in the width direction of the sheet before processing, regardless of processing information, as in the past. The processing time of the sheet S can be shortened as compared with the case where the conveyance of the sheet is resumed.

For example, when the slit Ja is cut and removed from the sheet S by the slitter mechanism 20 and reaches the cutter mechanism 22, the length Lx from the reference position B of the sheet S1 shown in FIG. 3 is 195 mm. In the conventional processing apparatus, the conveyance of the sheet is resumed when the upper blade reaches the upper limit position regardless of the size of the sheet. In this case, the waiting time from the table 1 to the resumption of conveyance after the processing in the cutter mechanism 22 is 50 msec.

In contrast, in the first embodiment, when the length Lx from the reference position B is 195 mm, the waiting time after processing in the cutter mechanism 22 is 30 msec from Table 1. With one cutting process, the waiting time can be reduced by 20 msec as compared with the prior art, and in the single sheet S1 shown in FIG. 3, since ten cutting lines K are set along the width direction W, the waiting time is reduced by 200 msec. .

In step 18 of FIG. 5, the control unit 45 determines whether or not the upper limit sensor 721 has changed from light transmission to light shielding by the light shielding plate 723 in order to detect that the upper blade 57 has reached the upper limit position. When the upper blade 57 reaches the upper limit position and the upper limit sensor 721 changes to light shielding, step 18 is satisfied and the routine proceeds to step 19. In step 19, the control unit 45 stops the contact / separation driving unit 70 and holds the upper blade 57 at the upper limit position. Proceeding to step 20, it is determined whether or not the next cutting line K is set according to the processing information.

If the next cutting line K is set, the process returns to step 12. Steps 12 to 20 are repeated until all the cutting lines K of the set number of sheets S are formed.

The chip J generated by the cutting process by the cutter mechanism 22 falls downward and is stored in the chip box 23. When all of the set number of sheets S are processed and the final cutting line K is formed, the process proceeds to step 21 in FIG. 5, and after the processed product Q is discharged to the paper receiving unit 3, the control unit 45 drives the conveyance. The parts 41 to 44 are stopped. The processed product Q conveyed to the paper receiver 2 is loaded on the paper receiver 222. And the driving | operation of the set processing operation is complete | finished.

(Second Embodiment)
In the first embodiment, when the cutter mechanism 22 starts the cutting process of the sheet S, the upper blade 57 as the processing member 51 is waiting at the upper limit position. After the sheet S conveyed to the cutter mechanism 22 was stopped at the cutting position, the upper blade 57 at the upper limit position was lowered and contacted with the lower blade 58 to cut the sheet S. In the second embodiment, instead of this, before the processing of the sheet S, the upper blade 57 as the processing member 51 is moved from the upper limit position to the standby position corresponding to the size of the sheet S. For this reason, the control unit 45 stores a program for controlling the movement operation of the processing member 51 by the moving unit 54 when the sheet S is conveyed to the installation position of the processing member 51 based on the size of the sheet S. Has been.

The standby position is a position where the upper blade 57 is closer to the lower blade 58 than when the length in the width direction W of the sheet S is short. As shown in FIG. 7, the upper blade 57 is inclined with respect to the lower blade 58, and the conveying position in the width direction W of the sheet S is the longitudinal direction of the upper blade 57 and the lower blade 58 as the processing die 52. In the case where the left side edge 18 of the sheet S is conveyed along the left side wall 18 shown in the left side in FIG. 7, the width of the sheet S3 shown in FIG. When the length L3 in the direction W is short, the lower position where the upper blade 57 is closer to the lower blade 58 is positioned as a standby position than when the length L2 in the width direction S of the sheet S shown in FIG. Even in this case, the sheet S can be passed between the upper blade 57 and the lower blade 58.

When the upper blade 57 is lowered for the cutting process, the distance that the upper blade 57 moves to the lower limit position is shorter when the upper blade 57 is in the standby position than when the upper blade 57 is in the upper limit position. Therefore, the time required for the sheet S cutting process can be shortened.

For this reason, before the cutting position of the sheet S reaches the cutter mechanism 22, the control unit 45 moves the upper blade 57 from the upper limit position to the standby position corresponding to the size of the sheet S and waits at the standby position. When the cutting line K forming position of the sheet S reaches the processing mold 51 installation position, the control unit 45 lowers the upper blade 57 at the standby position and performs cutting processing.

The storage device of the control unit 45 stores a table related to the time for driving the contact / separation driving unit 70 to move the processing member 51 to the standby position based on the size of the sheet S. Table 2 below is an example of a table relating to a movement time which is a time during which the control unit 45 drives the contact / separation driving unit 70 to move the upper blade 57 to the standby position.

In Table 2, the length Lx from the reference position B is the same as that in the first embodiment. The moving time shown in Table 2 is the time for the controller 45 to drive the contact / separation driving unit 70 when the upper blade 57 is moved from the upper limit position to the standby position. When the control unit 45 drives the contact / separation driving unit 70 for a predetermined movement time corresponding to the size of the sheet S before the processing of the sheet S, the upper blade 57 is moved from the upper limit position to the standby position.

The standby position may be such that the right end portion of the upper blade 57 is in contact with the lower blade 58 as shown in FIG. Even if a part of the upper blade 57 is in contact with the lower blade 58, the distance between the upper blade 57 and the lower blade 58 within the range in which the sheet S passes between the upper blade 57 and the lower blade 58 in the width direction W. It is only necessary that D3 is equal to or greater than a predetermined value through which the sheet S3 can pass. In this case, the sheet S3 is properly conveyed without being obstructed by the upper blade 57 in the downstream conveyance.

For the conveyance position of the sheet S in the width direction W, the control unit 45 sets the left end portion of FIG. 7 where the upper blade 57 as the pair of processing dies 52 contacts the lower blade 58 via the sheet S as the right end portion as shown in FIG. The sheet S is conveyed with higher priority. Thus, the standby position of the upper blade 57 can be set to a lower position, and the time required for the upper blade 57 to reach the lower limit position and cut the sheet S can be shortened.

It is detected by using the upper limit sensor 721 that the upper blade 57 is in the upper limit position. When the upper blade 57 is at the upper limit position, the upper limit sensor 721 is shielded by the light shielding plate 723. The control unit 45 uses any time point when the upper limit sensor 721 changes from light passing to light blocking or after that changes from light blocking to light passing to determine whether the upper blade 57 is in the upper limit position. it can.

Regarding the movement time illustrated in Table 2, when the length of the sheet S from the reference position B is less than 200 mm, the movement time is set to 30 msec. In this case, the control unit 45 stops the contact / separation drive unit 70 after 30 msec from the time when the upper limit sensor 721 detects that the upper blade 57 is at the upper limit position in a state where the contact / separation drive unit 70 is driven. . Then, at this standby position, the upper blade 57 is made to wait until the sheet S is conveyed to the cutter mechanism 22.

Also, from Table 2, when the length of the sheet S from the reference position B is 200 mm or more and less than 300 mm, the moving time is set to 20 msec. In this case, the contact / separation drive unit 70 is driven for 20 msec from the time when the upper blade 57 is at the upper limit position, and moves to the standby position. This standby position is a position higher than the standby position when the length of the sheet S from the reference position B is less than 200 mm, and the distance between the left end portions of both the upper blade 57 and the lower blade 58 in FIGS. , A more distant position.

When the length of the sheet S from the reference position B is 300 mm or more, the moving time is set to 10 msec. In this case, the control unit 45 drives the contact / separation driving unit 70 for 10 msec by moving the upper blade 57 at the upper limit position to the standby position. This standby position is the highest in comparison with other standby positions whose length from the reference position B of the sheet S is less than 300, and is slightly lower than the upper limit position.

In the second embodiment, processing information is acquired in step 101 during the control flow of the processing apparatus 100 shown in FIG. 4 as in the first embodiment. Then, the control unit 45 calculates the length Lx from the reference position B of the sheet S when the sheet S reaching the cutter mechanism 22 passes between the upper blade 57 and the lower blade 58. In the second embodiment, the control unit 45 further refers to the table exemplified in Table 2 of the storage device, and relates to the movement amount when the upper blade 57 as the processing member 51 is moved to the standby position. To get.

At the time of the processing preparation operation in step 102 in FIG. 4, the control unit 45 drives the contact / separation drive unit 70 to first move the upper blade 57 to the upper limit position. When the upper limit sensor 721 is blocked by the light shielding plate 723, the control unit 45 can determine that the upper blade 57 has reached the upper limit position. Alternatively, the control unit 45 continues to drive the contact / separation driving unit 70 even after the upper limit sensor 721 becomes light shielded, so that the upper limit sensor 721 changes from light shielding to light passing. In this way, the control unit 45 can also determine that the upper blade 57 is in the upper limit position when the upper limit sensor 721 has changed from light shielding to light passing.

By determining that the upper blade 57 is in the upper limit position when the upper limit sensor 721 changes from light blocking to light passing, the movement time when moving the upper blade 57 from the upper limit position to the standby position can be shortened, and the amount of movement can be reduced. Less. Thus, even when the control unit 45 drives the contact / separation drive unit 70 for the same drive time, the amount of movement of the upper blade 57 is the calculated value because the rotational speed varies due to individual differences in the motor. The amount by which the standby position shifts with slightly different values can be reduced. The upper blade 57 can be waited at a more accurate position.

When the control unit 45 detects that the upper blade 57 has reached the upper limit position, the control unit 45 starts measuring the movement time according to the size of the sheet S. And the control part 45 stops the contact / separation drive part 70, when predetermined | prescribed movement time passes. Thus, the upper blade 57 is moved from the upper limit position to the standby position, and waits for cutting processing at the standby position.

In step 103 in FIG. 4, the control unit 45 executes the processing of the sheet S. FIG. 8 shows a control flow when executing the cutting process as the processing process in the cutter mechanism 22 of the processing apparatus 100 according to the second embodiment. At step 31 in the figure, the control unit 45 conveys the sheet S by the conveyance unit 4, and when the cutting line K forming position of the sheet S reaches between the upper blade 57 and the lower blade 58 at step 32, the control is performed. The unit 45 stops the conveyance of the sheet S by the conveyance unit 4. In step 33, the control unit 45 drives the contact / separation drive unit 70 to start the processing operation. The upper blade 57 waiting at the standby position is moved downward by driving of the contact / separation driving unit 70.

In step 33, when the upper blade 57 starts to move from the standby position toward the lower limit position, the light shielding plate 723 has already been removed from the upper limit sensor 721, and the upper limit sensor 721 is light-transmitted. When the upper blade 57 reaches the lower limit position, the light shielding plate 723 is detached from the lower limit sensor 722, and both the upper limit sensor 721 and the lower limit sensor 722 are made to transmit light.

If it is detected in step 34 that the upper blade 57 has reached the lower limit position, step 34 is satisfied and the routine proceeds to step 35. In step 35, measurement of the standby time for resuming the conveyance of the sheet S is started. When the standby time reaches a predetermined standby time corresponding to the length Lx from the reference position B, step 36 is satisfied and the routine proceeds to step 37. In step 37, the control unit 45 drives the conveyance unit 4 to resume conveyance of the sheet S.

In step 38, when the control unit 45 detects that the upper blade 57 has reached the upper limit position, the control unit 45 proceeds to step 39 and starts measuring the movement time. Here, the detection of the upper limit position of the upper blade 57 may use either a change from light passing through the upper limit sensor 721 to light blocking or a change from light blocking to light passing. Further, instead of the detection result of the upper limit sensor 721, a predetermined time may elapse from another time such as detection of the lower limit position by a timer. When a predetermined moving time has elapsed in step 40, the process proceeds to step 41, where the control unit 45 stops the contact / separation driving unit 70, stops the movement of the upper blade 57 as the machining die 52, and moves the upper blade 57 to the standby position. Wait. In step 42, it is determined whether the next cutting line K is set according to the processing information.

If the next cutting line K is set, the process returns to step 32, and steps 32 to 42 are repeated until all the cutting lines K for the set number of sheets S are formed. When the cutting of the set number of sheets S is completed, the process proceeds to step 43, and after the workpiece Q is discharged to the paper receiving unit 2, the control unit 45 stops the conveying unit 4.

Thus, after the conveyance of the sheet S is stopped for the processing operation, the time for the upper blade 57 to move to the lower limit position can be shortened.

In the first and second embodiments, the processing unit is the cutter mechanism 22; however, the processing unit according to the present invention is not limited to this, and other processing processes such as a fold line forming mechanism and a perforation forming mechanism. You may comprise by the mechanism which performs. In addition, the processing member 51 includes a pair of processing dies 52 that sandwich and process the sheet S, and the pair of processing dies 52 includes an upper blade 57 and a lower blade 58. It may be a crease type consisting of a convex type provided with a convex part and a concave type provided with a concave groove, a perforated type forming a perforation on a sheet, a slitter type consisting of a round blade, a chamfering or punching die of a predetermined shape, etc. The structure may be such that the sheet is only brought into contact with one side without sandwiching the sheet.

Further, the control unit 45 controls at least one of the timing at which the conveyance of the sheet S is resumed by the conveyance unit 4 and the movement operation by the moving unit of the processing member when the sheet S is conveyed to the installation position of the processing member. At this time, the time from the time point detected by the upper limit sensor 721 or the lower limit sensor 722 is managed by the timer, but instead of this, the standby time or the movement time may be managed by the number of pulses of the encoder or the stepping motor. Further, instead of management by time and pulses, the timing of resuming the conveyance and the movement operation of the processed member before the processing may be controlled from the position, moving amount, moving speed, etc. of the processed member.

Further, the pair of processing members 51 is installed along the width direction W orthogonal to the conveyance direction F, but is not limited thereto, and may be installed along the conveyance direction like a rotary blade of a slitter mechanism, You may install along the crossing direction which inclines a predetermined angle with respect to a conveyance direction. When the processing member is installed along the conveyance direction, for example, when forming a perforation or a fold line in a part of the conveyance direction of the sheet, the control unit is based on the length of the conveyance direction of the sheet. After stopping the conveyance and moving the processing member by the moving unit to process the sheet, the timing when the conveyance unit resumes the conveyance of the sheet, and the processing member at the time when the sheet is conveyed to the installation position of the processing member It is possible to control at least one of the moving operations by the moving unit.

In addition, the moving unit 54 includes a contact / separation unit 61 that moves the pair of processing dies 52 in the contact / separation direction, but instead of this, the crossing direction intersecting the sheet conveyance direction including the width direction, the conveyance direction, and the like are predetermined. The processing member may be moved in the direction to process the sheet. Further, after processing the pair of processing dies 52 through the sheet S, the contact / separation portion 61 was controlled so as to separate the pair of processing dies 52. In addition, the processing time is adjusted based on whether the distance between the pair of processing dies 52 is equal to or greater than a predetermined value that can pass through the sheet S, but the round blade passes through the sheet along the concave groove or crosses the conveying direction. The sheet may be processed while rotating along the intersecting direction, such as processing the sheet, so that the pair of processing dies are not brought into and out of contact with each other and the distance between them is not changed.

Further, although the size of the sheet S is the length Lw, L1, L2 in the width direction W of the sheet S, the conveyance of the sheet is resumed based on the thickness of the sheet or the length in the conveyance direction. The processing time may be adjusted by controlling at least one of the movement of the processing member by the moving unit at the time when the sheet is conveyed to the installation position of the processing member. For example, when the sheet is thin, the conveyance of the sheet may be resumed at a predetermined timing when the distance between the pair of processing members is shorter than when the sheet is thick. When a processing member that can partially form either a cutting line, a fold line, or a perforation line along the conveyance direction is processed to come into contact with or separate from the sheet, the processing member is long when the length in the conveyance direction of the sheet is short. From time to time, the conveyance of the sheet may be resumed at a predetermined timing when the distance between the sheet and the processing member is short.

Further, the control unit 45 controls the timing at which the conveyance of the sheet S is resumed based on the size of the sheet S, or the timing at which the conveyance of the sheet S is resumed and the installation position of the processing member 51 Although the case where both the movements of the processing member 51 by the moving unit 54 at the time of conveyance are controlled is shown, the timing at which the conveyance of the sheet is resumed is constant regardless of the size of the sheet, and the processing member 51 is set to the installation position. The movement by the moving part of the processing member at the time when the sheet is conveyed may be controlled based on the size of the sheet.

Further, when controlling the movement of the processing member 51 when the sheet S is conveyed to the installation position of the processing member 51 by the moving unit 54, the upper blade 57 as the processing member 51 is moved to the upper limit position during the processing preparation operation. Although the case where the sheet S is moved to the standby position corresponding to the size of the sheet S and waits at this standby position until the processing is performed is shown, the processing member is moved when the sheet S is conveyed to the installation position of the processing member 51. 51 may be positioned at a predetermined standby position, for example, when the sheet conveyed to the processing unit is stopped for processing, the timing is adjusted so that the processing member is positioned at the standby position, You may adjust the drive start time of a moving part. In this case, the processing member may be stopped for a while at the standby position, or the moving operation may be continued without stopping. Therefore, for example, the control unit 45 starts driving the contact / separation driving unit 70 after a predetermined time has elapsed after the fourth detection unit 94 of FIG. 1 detects the front edge Sf of the sheet S, and the upper blade without stopping at the standby position. 57 may be lowered and processed.

Further, the control unit 45 causes the conveyance unit 4 and the movement unit 54 to shorten the time required for the processing of the sheet S when the length is shorter than when the length in the intersecting direction intersecting the conveyance direction of the sheet S is long. However, the sheet processing time may be controlled to be shortened when the length is longer than when the length in the intersecting direction intersecting the sheet conveyance direction is shorter.

Further, the timing at which the pair of processing dies 51 are separated before and after the processing of the sheet S is made different in the width direction W, and the transport position in the width direction W perpendicular to the transport direction of the sheet S is set by the pair of processing dies 51. The sheet is conveyed by giving priority to the place where the separation timing is early over the place where the separation is late, but the pair of processing members are configured to extend along the horizontal direction, for example, so that the pair of processing members extends in the cross direction including the width direction. The case where the timing which a process member separates may be the same. Moreover, although the case where one end portion of the upper blade 57 as the processing member 51 is separated earlier than the other end portion is shown, when the central portion in the longitudinal direction of the processing member is separated earlier than both end portions, By transporting the sheet with priority given to the central position in the width direction, a sheet having a short length in the width direction can be processed faster than a long sheet, and the processing time can be shortened.

Although the slitter mechanism as a slitter processing unit for cutting the sheet along the conveying direction is provided on the upstream side of the cutter mechanism, the slitter mechanism may not be provided on the upstream side.

Further, the arrangement pattern of the sheets S1 and S4 is not limited to the one illustrated in FIG. 3, and various other patterns can be set for the number and position of the cutting lines T and K and the broken lines.

Moreover, although the conveyance part 4 was comprised by a pair of upper and lower conveyance rollers, it may replace with a conveyance roller and may use a belt. Moreover, although the control part 45 driven the some conveyance drive parts 41-44 synchronously, you may drive individually, without synchronizing. Then, the conveyance of the sheet S by the conveyance unit 4 is started and stopped in the entire apparatus, but the conveyance state is continued for each processing unit such as continuing conveyance at another place while the conveyance is stopped at one place in the apparatus. May be different.

Various processing information is manually set by the user from the operation panel 46 or automatically input by reading the barcode M2 by the reading unit 26, but is set by communicating with an external information processing apparatus such as a personal computer. May be. Alternatively, a plurality of sheet arrangement patterns may be stored in advance in the storage means by manual input from the operation panel, and each pattern may be called and set by a number or the like.
