Hereinafter, exemplary embodiments of a component supply device according to the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the specific configurations of the following embodiments, and configurations based on similar technical ideas are included in the present disclosure.
Hereinafter, an embodiment of the present disclosure will be described with reference to
[Overall Configuration of Sheet Processing System 1]
A sheet processing system 1 of the present embodiment includes a printing device 8, a sheet feeding device 10, a first machining device 20, a cross conveyor device 30, an insertion unit 40, a second machining device 50, and a conveyor stacker device 60 in this order from the upstream side in the conveyance direction. Furthermore, the sheet processing system 1 includes a device for generating processing job 70 that generates a processing job having contents to be processed by the first machining device 20 and the second machining device 50.
In recent years, the maximum printable sheet size in a general-purpose printing machine tends to increase, and for example, printing sizes exceeding B3 size are also becoming possible in many cases. The present sheet processing system 1 performs processing of receiving a sheet Sh having a size equal to or larger than a certain size printed by the printing device 8, creating an intermediate sheet Sh1 by cutting a margin portion of the printed sheet Sh by the first machining device 20, and leaving only a product P which is a printed portion by the second machining device 50. Note that the first machining device 20 may cut off the margin portion Sh2 on the front end side from the sheet Sh.
The second machining device 50 is a general-purpose sheet cutting device generally used in the market in the related art, and the maximum sheet size that can be processed is, for example, B3 size. Furthermore, the first machining device 20 can process a sheet having a size larger than that of the second machining device 50, and can process a size exceeding B3 size, for example. The present sheet processing system 1 is configured to perform cutting processing to a sheet size that can be received by the second machining device 50 by the first machining device 20, and then deliver the processed sheet to the second machining device 50.
The printing device 8 prints the product P on the sheet Sh based on the layout information. The printed sheet Sh is conveyed to the sheet feeding device 10, and is conveyed to the first machining device 20 as it is or stored in the sheet feeding device 10. Furthermore, the printing device 8 may not be connected to the sheet feeding device 10, and in this case, the printed sheet Sh is conveyed to the sheet feeding device 10 by the operator.
In the present embodiment, the sheet feeding device 10 is configured to be able to feed a sheet having a maximum B2 size. The sheet feeding device 10 conveys the sheet Sh to the first machining device 20, and a driving roller 23 of the first machining device 20 conveys the sheet Sh in the first direction. The first machining device 20 processes the sheet Sh based on the timing at which the front end of the sheet Sh reaches the front end detection sensor 21 of the first machining device 20.
The first machining device 20 is installed to perform cutting processing (primary processing) in advance to a sheet size that can be received by the general-purpose second machining device 50, and includes a front end detection sensor 21 (21a, 21b) that detects that a front end of the sheet Sh conveyed from the sheet feeding device 10 has reached, and a laser sensor 27 (27a, 27b) that detects positions of the front end of the sheet Sh and a register mark provided on the sheet Sh in advance, and detects an inclination angle of the print image with respect to the sheet conveyance direction. Note that the front end detection sensor 21 and the laser sensor 27 are disposed at two locations in the width direction orthogonal to the sheet conveyance direction.
Furthermore, the first machining device 20 includes an angle adjuster capable of adjusting the angle of the cutting mechanism 20a of the cross-cut portion to be perpendicular to the conveyance direction of the print image based on the inclination angle of the print image detected by the laser sensor 27. After stopping the sheet Sh at a preset cutting position, the cutting mechanism 20a cuts the sheet Sh by moving a pair of upper and lower rotary blades 20aa in a width direction orthogonal to a direction in which the sheet Sh is conveyed. The pair of upper and lower rotary blades 20aa of the movable blade unit are disposed to face each other on the upper side and the lower side via a path through which the sheet Sh is conveyed. In this manner, the first machining device 20 cuts the conveyed sheet Sh at the cutting position according to the processing job to separate the sheet Sh into the intermediate sheet Sh1 and the unnecessary margin portion Sh2. The unnecessary margin portion Sh2 that does not include the product P is discharged from the conveying path and discarded. The cutting position is a cutting line on the sheet Sh where the sheet Sh is cut by the first machining device 20, and may be one or a plurality of cutting positions.
The intermediate sheet Sh1 after the cutting is discharged to the cross conveyor device 30 by a pair of conveying rollers. The discharge of the intermediate sheet Sh1 is detected by a discharge sensor (not illustrated). Note that, in a case where a guillotine type cutting blade is used as a cutting blade for preliminarily cutting (primary processing) a large-sized sheet Sh, a blade long in the width direction of the sheet is required, which causes problems of warpage and distortion. On the other hand, when a pair of upper and lower rotary blades movable in the sheet conveyance direction is used, the problems of warpage and distortion are solved, which is suitable for the first machining device 20.
The cross conveyor device 30 receives the intermediate sheet Sh1 cut by the first machining device 20 and conveyed in the first direction, conveys the intermediate sheet Sh1 in the second direction intersecting the first direction, and sends the intermediate sheet Sh1 to the second machining device 50. Note that the cross conveyor device 30 is disposed at a subsequent stage of the first machining device 20, and includes an oblique conveying unit that receives the intermediate sheet Sh1 discharged from the first machining device 20 on the endless belt 31 (single belt having a predetermined width), and conveys the intermediate sheet Sh1 toward the downstream side in the conveyance direction while conveying the intermediate sheet Sh1 obliquely toward the guide wall 32 such that an end edge of the received intermediate sheet Sh1 is along the guide wall 32. An insertion unit 40 that delivers the intermediate sheet Sh1 discharged from the cross conveyor device 30 to a sheet feed port of the second machining device 50 is disposed at a subsequent stage of the cross conveyor device 30. Note that the insertion unit 40 includes an oblique conveyance unit that conveys the received intermediate sheet Sh1 toward the downstream side in the conveyance direction while conveying the intermediate sheet Sh1 by air suction obliquely toward the guide wall 41 so that the end edge of the received intermediate sheet Sh1 is along the guide wall 41.
The second machining device 50 is a sheet cutting device that is conventionally and widely used in the market. The intermediate sheet Sh1 cut (primarily processed) in advance into a sheet size that can be received by the second machining device 50 by the first machining device 20 is delivered from the insertion unit 40 to the sheet feed port of the second machining device 50. Thereafter, a driving roller 51 of the second machining device 50 feeds the intermediate sheets Sh1 one by one in the sheet conveyance direction, i.e. in the second direction. The second machining device 50 cuts the fed intermediate sheets Sh1 while conveying the intermediate sheets Sh1 by the device body based on the content of the processing job sent from the device for generating processing job 70, and discharges the product P after the cutting from the device body. The second machining device 50 includes a guillotine type blade 50a that stops the intermediate sheet Sh1 conveyed in the second direction and cuts the intermediate sheet Sh1 in the first direction, and a rotary blade 50b that cuts the intermediate sheet Sh1 in the second direction while conveying the intermediate sheet Sh1 in the second direction. The sheet Sh needs to be cut by the rotary blade 20aa of the first machining device 20 so as to be equal to or smaller than the maximum size of the intermediate sheet Sh that can be processed by the second machining device 50. At the time of cutting, the rotary blade 20aa of the first machining device 20 stops the conveyance of the sheet Sh and then moves the rotary blade 20aa in the second direction to cut the sheet Sh, so that processing by the rotary blade 20aa takes time. On the other hand, the position of the rotary blade 50b of the second machining device 50 can be adjusted in the first direction, and the rotary blade 50b can cut the intermediate sheet Sh1 while conveying the intermediate sheet Sh1 in the second direction, so that the processing time can be shortened. Therefore, the processing time can be shortened when the cutting of the sheet Sh in the second direction is performed in the second machining device 50 rather than in the first machining device 20.
The second machining device 50 may perform, for example, perforation processing, vertical folding die processing, horizontal folding die processing, rounding processing, embossing processing, die cutting processing, vertical folding processing, horizontal folding processing, simulated adhesion, adhesion, binding processing, or the like on the intermediate sheet Sh1 in addition to processing into the product P by vertical cutting and horizontal cutting processing. The product P is a product obtained as a result of processing the sheet Sh by the sheet processing system 1, and includes, for example, a ticket with a banknote and a flier with a banknote.
The conveyor stacker device 60 may be coupled to the discharge side of the second machining device 50. The conveyor stacker device 60 is a device that conveys the product P after the cutting process discharged from the second machining device 50 slowly by a belt conveyor, and stacks the unit cards in a state of being obliquely erected on a stacker 61 provided at an end portion thereof.
[Device for Generating Processing Job]
Next, the device for generating processing job 70 will be described in more detail with reference to
The layout information creation unit 71 creates the first layout information 81 in which the product P is disposed on the sheet Sh according to a predetermined procedure based on the size in the longitudinal direction and the size in the lateral direction of the product P and the size of the sheet Sh on which the product P is to be printed. The layout information creation unit 71 duplicates the product P, performs imposition by setting the position of the duplicated product P based on the size of the product P, and creates the first layout information 81. For example, as illustrated in
When imposing the product P, the layout information creation unit 71 sets the sheet front edge margin width Aw1 from the front end of the sheet Sh to the front end of the contour Pa of the product P to be equal to or larger than the minimum front end cut width Cw1 and equal to or smaller than the maximum size that can be discharged by the first machining device 20. The sheet front edge margin width Aw1 is a length of the margin region Ar1 on the front end side between the contour SL1 of the sheet Sh and the contour Pa of the product P in the first direction. The minimum front end cut width Cw1 is, for example, 15 mm. Here, the contour Pa of the product P is a contour of a region including a plurality of products P in a case where the plurality of products P are arranged on the sheet Sh. Note that the minimum front end cut width Cw1 refers to the minimum front end cut width of the sheet Sh that can be cut by the first machining device 20.
When imposing the product P, the layout information creation unit 71 sets the sheet rear edge margin width Aw2 from the rear end of the sheet Sh to the rear end of the contour Pa of the product P to be equal to or larger than the minimum rear end cut width Cw2 and equal to or smaller than the maximum size that can be discharged by the first machining device 20. The sheet rear edge margin width Aw2 is a length of the margin region Ar2 on the rear end side between the contour SL1 of the sheet Sh and the contour Pa of the product P in the first direction. Each of the margin region Ar1 and the margin region Ar2 corresponds to a first margin region. The minimum rear end cut width Cw2 is, for example, 10 mm. Furthermore, the layout information creation unit 71 sets the margin widths Mw1 to Mw3 between the respective products P arranged in the first direction. The number of margin widths is smaller by one than the imposition number. Note that the minimum rear end cut width Cw2 refers to the minimum rear end cut width of the sheet Sh that can be cut by the first machining device 20.
The layout information creation unit 71 also generates the second layout information 82 after the sheet Sh of the first layout information 81 is cut by the first machining device 20. The second layout information 82 is information regarding the position of the product P disposed on the intermediate sheet Sh1. In the second layout information 82, the size Sz3 of the intermediate sheet Sh1 in the first direction is set to a size within a range between the maximum size and the minimum size that can be conveyed by the cross conveyor device 30 and the second machining device 50, and is set to, for example, 190 to 370 mm.
In the second layout information 82, the layout information creation unit 71 sets the sheet front edge margin width Aw3 from the front end of the intermediate sheet Sh1 to the front end of the contour Pb of the product P and the sheet rear edge margin width Aw4 from the rear end of the intermediate sheet Sh1 to the rear end of the contour Pb of the product P within the range of the processable width Cw3. The sheet front edge margin width Aw3 is a length of the margin region Ar3 on the front end side in the first direction between the contour SL2 of the intermediate sheet Sh1 and the contour Pb of the product P. The sheet rear edge margin width Aw4 is a length of a margin region Ar4 on the rear end side in the first direction between the contour SL2 of the intermediate sheet Sh1 and the contour Pb of the product P. The margin region Ar3 and the margin region Ar4 each correspond to a second margin region. The processable width Cw3 is an allowable range of the margin lengths of the upstream end and the downstream end of the intermediate sheet Sh1 in the conveyance direction of the first machining device 20 after being cut by the first machining device 20 on the upstream side. In a case where the sheet front edge margin width Aw3 on the upstream side and the sheet rear edge margin width Aw4 on the downstream side of the intermediate sheet Sh1 in the first direction exceed the range of the processable width Cw3, the intermediate sheet Sh1 cannot be processed by the second machining device 50. The processable width Cw3 has a minimum value and a maximum value, and a range thereof is, for example, 4.2 to 55 mm. Here, the contour Pb of the product P is a contour of a region including a plurality of products P in a case where the plurality of products P are arranged on the intermediate sheet Sh1.
In the second layout information 82, the layout information creation unit 71 sets the margin width Dw3 in the first direction of the margin region Ar5 between the respective products P arranged in the first direction within the range of the processable width Mw5. The margin region Ar5 corresponds to a third margin region. The processable width Mw5 is an allowable range of the margin length between the products P that can be processed by the second machining device 50. The processable width Mw5 has a minimum value and a maximum value, and a range thereof is, for example, 5 to 15 mm. As described above, the margin length between the products P in the first direction may be different from the allowable range of the margin length at the upstream end and the downstream end of the intermediate sheet Sh1.
In the second layout information 82, the imposition number of the intermediate sheet Sh1 in the first direction is changed according to the performance of the second machining device 50. The number of impositions of the intermediate sheet Sh1 in the first direction is set to, for example, one to five. For example, the number of impositions of the intermediate sheet Sh1 in
The layout information creation unit 71 may create the layout information again after searching for cutting position candidates of the processing position search unit 73.
The processing position search unit 73 includes a cutting position candidate search unit 73a that searches for a candidate for a cutting position to be cut by the first machining device 20, and a cutting position candidate selection unit 73b that selects an appropriate candidate from the searched cutting position candidates.
As illustrated in
The cutting position candidate search unit 73a further generates combination candidates of cutting position candidates based on the sheet size in the first direction that can be conveyed by the second machining device 50.
The cutting position candidate selection unit 73b erases an inappropriate candidate from the candidates searched by the cutting position candidate search unit 73a. For example, as illustrated in
Furthermore, as illustrated in
The cutting position candidate selection unit 73b may further select an appropriate cutting position from the combination candidates of the cutting positions on the basis of a predetermined candidate setting rule. For example, as illustrated in
Furthermore, the number of imposition divisions may be set as a rule. In
The determination unit 75 determines whether or not the first machining device 20 can cut with the cutting position candidates searched by the processing position search unit 73. Furthermore, it is determined whether or not the intermediate sheet Sh1 cut and divided at the cutting position can be conveyed by the second machining device 50. The determination unit 75 determines that the searched candidate can be processed in a case where both determination results are possible, and determines that the searched candidate cannot be processed in a case where at least one of both determination results is not possible.
The processing job generation unit 77 generates a processing job to be processed by the first machining device 20 and the second machining device 50 on the basis of the cutting position candidates determined to be processable by the determination unit 75.
The processing job includes information such as the size and type of the sheet, the size and arrangement of the product on the sheet, and the position, type, number, and dimension of processing performed on the sheet. That is, the information included in the processing job may be only the information of the processing position, a combination of the processing position and the processing type, a combination of the processing position and the arrangement of the product, or a combination of the processing position, the processing type, and the arrangement of the product.
The storage unit 79 includes a non-transitory storage medium that stores a program, data, or the like necessary for the device for generating processing job 70 to generate a processing job, and includes, for example, at least one of a ROM, an HDD, and an SSD. The storage unit 79 also includes a temporary storage medium such as a RAM. The information on the product to be printed on the sheet Sh is stored in, for example, the storage unit 79 or an external device (not illustrated). The external device is, for example, a personal computer, a smartphone, or a tablet PC, and is connected to the device for generating processing job 70 via a communication network.
The device for generating processing job 70 including the layout information creation unit 71, the processing position search unit 73, the determination unit 75, and the processing job generation unit 77 includes a processor of one or a plurality of integrated circuits, for example, a microcomputer, a CPU, an MPU, a GPU, a DSP, an FPGA, or an ASIC, and each function is implemented by the integrated circuit reading data and programs stored in the storage unit 79 and performing various arithmetic processing. The function of the device for generating processing job 70 may be configured only by hardware or may be realized by combining hardware and software.
Next, a flow in which the device for generating processing job 70 reads a program stored in the storage unit 79 and generates a processing job will be described with reference to
In step S1, in the device for generating processing job 70, when an instruction of processing job generation is input from the user, the layout information creation unit 71 generates and acquires the first layout information 81 according to a predetermined method on the basis of the size of the intermediate sheet Sh1 and the size of the product P. Note that the device for generating processing job 70 may acquire the first layout information 81 from the storage unit 79 or an external device (not illustrated) instead of generating the first layout information 81.
In step S2, as described above, the cutting position candidate search unit 73a of the processing position search unit 73 searches for cutting position candidates in the first layout information 81.
In step S3, as described above, the cutting position candidate selection unit 73b of the processing position search unit 73 selects an appropriate candidate from among the plurality of searched cutting position candidates. Note that selection of a candidate will be described in more detail with reference to
The cutting position candidate selection unit 73b uses the sheet front edge margin width Aw1 and the margin width Dw1 between the products P in which the cutting position candidate Cp is set to select the cutting position candidate based on the selection condition 1 including the following fourth to sixth conditions.
Fourth condition: sheet front edge margin width Aw1<(margin width Dw1 between products P)/2
Fifth condition: The sheet skew feeding correction function in the first machining device 20 is set to OFF.
In a case where all of the fourth condition and the fifth condition are satisfied, a candidate in which the candidate Cp1 for the cutting position is not set in the sheet front edge margin width Aw1 is selected.
Sixth condition: sheet rear edge margin width Aw2<maximum value of processable width Cw3
In a case where the sixth condition is satisfied, a candidate in which the candidate Cp5 for the cutting position is not set in the sheet rear edge margin width Aw2 is selected.
Therefore, in a case where the selection condition 1 is satisfied, only the cutting position candidate Cp3 illustrated in
In step S4, the determination unit 75 determines whether or not processing with the cutting position candidate selected in step S3 can be performed. The determination unit 75 determines whether or not the processing content is within the range of the specification. For example, as illustrated in
In
In a case where the determination unit 75 determines that the processing based on the selected processing position candidate cannot be performed (No in step S4) and in a case where the candidate cannot be selected under the selection condition 1 in step S3, the layout information creation unit 71 creates new third layout information in step S6.
As illustrated in
In step S7, the determination unit 75 determines whether the new third layout information 83 and the fourth layout information 84 cut by the cutting position candidates Cp1 and Cp3 of the third layout information 83 are executable. The determination criterion is the same as that in step S4, but in a case where the sheet rear edge margin width Aw2a is larger than a predetermined threshold, it may be determined that the sheet rear edge margin width Aw2a is not executable. Here, the fourth layout information 84 is information regarding the position of the product P disposed on the intermediate sheet Sh1 generated by cutting the sheet Sh with the candidate Cp of the cutting position set in the third layout information 83. In the determination by the determination unit 75, the new third layout information 83 and the new fourth layout information 84 are selected on the basis of the maximum size and the minimum size of the intermediate sheet Sh1 in the first direction, which can be conveyed by the second machining device 50, and the size of the product P.
When the determination unit 75 determines that the processing based on the new third layout information 83 and the fourth layout information 84 can be performed (Yes in step S7), steps S2 and S3 are performed based on the newly created third layout information 83. That is, based on the newly created third layout information 83, the cutting position candidate search unit 73a of the processing position search unit 73 again searches the third layout information 83 for cutting position candidates, and the cutting position candidate selection unit 73b of the processing position search unit 73 selects an appropriate candidate from among the plurality of searched cutting position candidates. Thereafter, in step S5, the processing job generation unit 77 generates a processing job by adopting the newly created third layout information 83 and fourth layout information 84.
In a case where the determination unit 75 determines that the processing based on the new third layout information 83 and the fourth layout information 84 cannot be performed (No in step S7) and in a case where the third layout information 83 cannot be created in step S6, the layout information creation unit 71 creates the new fifth layout information 85 in step S8.
For example, as illustrated in
In such a case, in step S8, the layout information creation unit 71 creates new fifth layout information 85 as illustrated in
The layout information creation unit 71 sets the distance Cr1 from the front end of the sheet Sh to the candidate Cp1 for the cutting position at the position closest to the front end of the sheet Sh to a width that can be processed by the first machining device 20, but sets the distance Cr1 to the minimum front end cut width Cw1 in this example. As the margin width Dw1b between the products P in which the candidate Cp3 for the cutting position is set, for example, a value obtained by dividing the sum of the sheet rear edge margin width Aw2 in the first layout information 81 of
Dw1b=(Aw2+Dw1+(Aw1−Cr1))/N
Note that, in the example of
The sheet front edge margin width Aw1b in the fifth layout information 85 is calculated by, for example, the sum of the distance Cr1 and the half value of the margin width Dw1b between the products P. That is, it is set by the following equation.
Aw1b=Cr1+(Dw1b/2)
The sheet rear edge margin width Aw2b in the fifth layout information 85 is calculated by subtracting a difference K3 between the sheet front edge margin width Aw1b and the sheet front edge margin width Aw1 in
Aw2b=Aw2−(Aw1b−Aw1)−(Dw1b-Dw1)
In the fifth layout information 85 illustrated in
The layout information creation unit 71 sets the margin widths Dw3a and Dw3b in the first direction of the margin regions Ar5a and Ar5b between the respective products P arranged in the first direction on the respective intermediate sheets Sh1a and Sh1b within the range of the processable width Mw5 within the range of the maximum size and the minimum size that can be processed by the second machining device 50. The sheet front edge margin width Aw3a of the intermediate sheet Sh1a and the sheet front edge margin width Aw3b of the intermediate sheet Sh1b have the same length, and the sheet rear edge margin width Aw4a of the intermediate sheet Shia and the sheet rear edge margin width Aw4b of the intermediate sheet Sh1b have the same length. Furthermore, the margin width Dw3a between the products P of the intermediate sheet Shia and the margin width Dw3b between the products P of the intermediate sheet Sh1b are both equal to the margin width Dw2 between the products P of the sheet Sh in
Note that steps S2 and S3 may be performed based on the newly created fifth layout information 85. That is, based on the newly created fifth layout information 85, in the processing position search unit 73, the cutting position candidate search unit 73a again searches the first layout information 81 for cutting position candidates, and the cutting position candidate selection unit 73b of the processing position search unit 73 selects an appropriate candidate from among the plurality of searched cutting position candidates.
In step S10, similarly to step S4, the determination unit 75 determines whether the new fifth layout information 85 and the sixth layout information 86 cut by the cutting position candidates Cp1 and Cp3 of the fifth layout information 85 are executable. Here, the sixth layout information 86 is information regarding the position of the product P disposed on the intermediate sheets Sh1a and Sh1b generated by cutting the sheet Sh with the cutting position candidates Cp1 and Cp3 set in the fifth layout information 85.
When the determination unit 75 determines that the processing based on the new fifth layout information 85 and the new sixth layout information 86 can be performed (Yes in step S10), in step S5, the processing job generation unit 77 generates a processing job by adopting the newly created fifth layout information 85 and sixth layout information 86.
In a case where the determination unit 75 determines that the processing based on the new fifth layout information 85 and the sixth layout information 86 cannot be performed (No in step S10) and in a case where the fifth layout information 85 cannot be created in step S8, the process proceeds to step S11.
In step S11, as illustrated in
Seventh condition: In a case where there are two candidates for the cutting position (Cp1, Cp6) within the sheet front edge margin width Aw1, the position of the candidate Cp1 for the cutting position closer to the product P is changed to the front end side. In this case, the size from the position of the candidate Cp1 for the cutting position in the first direction to the front end of the sheet Sh is Sz3d. In a case where the position of the candidate Cp1 after the change is the candidate Cp1a, the size from the position of the candidate Cp1a of the cutting position in the first direction to the front end of the sheet Sh is Sz3da. This size Sz3da is less than the maximum discharge size that can be discharged by the first machining device 20. The maximum discharge size is, for example, 190 mm.
Eighth condition: In a case where there are two candidates for the cutting position within the sheet rear edge margin width Aw2 (Cp5, Cp7), the position of the candidate Cp5 for the cutting position closer to the product P is changed to the rear end side. In this case, the size from the position of the candidate Cp5 for the cutting position in the first direction to the rear end of the sheet Sh is Sz3e. In a case where the position of the candidate Cp5 after the change is the candidate Cp5a, the size from the position of the candidate Cp5a of the cutting position in the first direction to the rear end of the sheet Sh is Sz3ea. This size Sz3ea is less than the maximum discharge size that can be discharged by the first machining device 20. At this time, the distance La between the candidate Cp1 a for the cutting position and the contour Pa of the product P (corresponding to the length of the margin region Ar3 of the intermediate sheet Sh1) and the distance Lb between the candidate Cp5a for the cutting position and the contour Pa of the product P (corresponding to the length of the margin region Ar4 of the intermediate sheet Sh1) must be within the range of the processable width Cw3, and is, for example, 4.2 to 55 mm. Furthermore, the size from the candidate Cp1 a to the candidate Cp5a of the cutting position in the first direction is set within the range of the maximum size and the minimum size in the first direction of the intermediate sheet Sh1 that can be conveyed by the second machining device 50.
In a case where the seventh condition is satisfied, as illustrated in
In step S13, the determination unit 75 determines whether or not the second layout information cut by the new cutting position candidates Cp1a and Cp5a and the cutting position candidates Cp1a and Cp5a in the first layout information 81 can be implemented by the first machining device 20 and the second machining device 50, respectively.
When the determination unit 75 determines that the processing with the new cutting position candidate can be performed (Yes in step S13), in step S5, the processing job generation unit 77 generates a processing job by adopting the newly set cutting position candidates Cp1a and Cp5a. In a case where there are a plurality of types of possible new cutting position candidates, the determination unit 75 selects a candidate having a small number of cutting positions.
In a case where the determination unit 75 determines that the process using the new cutting position candidates cannot be performed (No in step S13) or in a case where the cutting position candidates Cp1a and Cp5a cannot be set in step S11 (No in step S12), a candidate having the smallest number of cutting position candidates is selected from the candidates searched in step S2, and a processing job is generated and terminated.
As described above, the sheet processing system 1 according to the embodiment includes the first machining device 20, the second machining device 50, and the device for generating processing job 70. The first machining device 20 conveys the sheet Sh on which at least one product P is disposed in a first direction that is a conveyance direction of the first machining device, cuts the sheet Sh at at least one cutting position according to the processing job in a state where the sheet Sh is stopped, and discharges the intermediate sheet Sh1. The second machining device 50 processes the intermediate sheet Sh1 discharged from the first machining device 20 according to the processing job, and discharges the product P. The device for generating processing job 70 instructs processing contents to be performed by each of the first machining device 20 and the second machining device 50. The device for generating processing job 70 searches for at least one cutting position candidate Cp on the basis of the first layout information 81 that is information regarding the position of the product P disposed on the sheet Sh, selects, from among the candidates Cp for the cutting position, a candidate having a small number of cutting positions that can be processed by the first machining device 20 and the second machining device 50 on the basis of the maximum sizes of the sheet front edge margin width Aw1 and the sheet rear edge margin width Aw2 of the margin regions Ar1 and Ar2 between the contour SL1 of the sheet Sh and the contour Pa of the product P in the first direction, which can be discharged by the first machining device 20, and the maximum size and the minimum size of the intermediate sheet Sh1 in the first direction, which can be conveyed by the second machining device 50, and generates a processing job for performing processing at the selected cutting position.
Furthermore, the processing job generation program according to the embodiment causes, for example, the processing job generation unit 77 including an integrated circuit to generate, in the sheet processing system 1, a processing job that gives an instruction on processing contents to be performed by each of the first machining device 20 and the second machining device 50. According to the processing job generation program, for example, the processing job generation unit 77 including an integrated circuit acquires the first layout information 81 that is information regarding a position of the product P disposed on the sheet Sh, searches for at least one candidate Cp for a cutting position on the basis of the first layout information 81, selects, from among the candidates Cp for the cutting position, a candidate having a small number of cutting positions that can be processed by the first machining device 20 and the second machining device 50 on the basis of the maximum sizes of the sheet front edge margin width Aw1 and the sheet rear edge margin width Aw2 of the margin regions Ar1 and Ar2 between the contour SL1 of the sheet Sh and the contour Pa of the product P in the first direction, which can be discharged by the first machining device 20, and the maximum size and the minimum size of the intermediate sheet Sh1 in the first direction, which can be conveyed by the second machining device 50, and generates a processing job for performing processing at the selected cutting position.
By reducing the number of times of cutting by stopping the sheet Sh in the first machining device 20, the time required for processing of the entire sheet processing system 1 can be shortened, and wear of the rotary blade 20aa of the first machining device 20 that cuts the sheet Sh can be suppressed.
In a case where the sheet Sh is divided into the plurality of intermediate sheets Sh1a and Sh1b in the first machining device 20, the device for generating processing job 70 creates new fifth layout information 85 on the basis of the given first layout information 81 that is information regarding the position of the product P disposed on the sheet Sh, the maximum size and the minimum size of the intermediate sheets Sh1 a and Sh1b in the first direction that can be conveyed by the second machining device 50, the maximum size and the minimum size of the margin regions Ar3a, Ar4a, Ar3b, and Ar4b in the first direction between the contours SL2a and SL2b of the intermediate sheets Sh1a and Sh1b that can be processed by the second machining device 50 and the contours Pba and Pbb of the product P, and the size of the product P. The device for generating processing job 70 searches for at least one candidate Cp for the cutting position on the basis of the new fifth layout information 85 instead of the first layout information 81, selects, from among the candidates Cp for the cutting position, a candidate having a small number of cutting positions that can be processed by the first machining device 20 and the second machining device 50 on the basis of the maximum sizes of the sheet front edge margin width Aw1b and the sheet rear edge margin width Aw2b of the margin regions Ar1b and Ar2b between the contour SL1 of the sheet Sh and the contour Pa of the product P in the first direction, which can be discharged by the first machining device 20, and the maximum size and the minimum size of the intermediate sheet Sh1 in the first direction, which can be conveyed by the second machining device 50, and generates a processing job for performing processing at the selected cutting position.
The device for generating processing job 70 creates new sixth layout information 85 such that a layout of each of products P on the plurality of intermediate sheets Sh1a and Sh1b becomes the same among the plurality of intermediate sheets Sh1 a and Sh1b.
On the basis of, in addition to the maximum size in the first direction that can be discharged by the first machining device 20 and the maximum size and the minimum size in the first direction of the intermediate sheet Sh1 that can be conveyed by the second machining device 50, the maximum size and the minimum size in the first direction of the margin regions Ar3 and Ar4 between the contour SL2 of the intermediate sheet Sh1 that can be processed by the second machining device 50 and the contour Pb of the product P, the device for generating processing job 70 corrects candidates for the cutting position Cp and selects a candidate that can be processed by the first machining device 20 and the second machining device 50 and has a small number of cutting positions from among the candidates for the cutting position Cp.
In a case where the sheet Sh is divided into the plurality of intermediate sheets Sh1 a and Sh1b in the first machining device 20, the device for generating processing job 70 creates new fifth layout information 85 on the basis of the given first layout information 81 that is information regarding the position of the product P disposed on the sheet Sh, the maximum size and the minimum size of the intermediate sheets Sh1 a and Sh1b in the first direction that can be conveyed by the second machining device 50, the maximum size and the minimum size of the margin regions Ar3a, Ar4a, Ar3b, and Ar4b in the first direction of the intermediate sheets Sh1 a and Sh1b that can be processed by the second machining device 50, the maximum size and the minimum size in the first direction of the margin regions Ar5a, Ar5b between the products P disposed on one of the intermediate sheets Sh1 a and Sh1b that can be processed by the second machining device 50 and disposed at adjacent positions, and the size of the products P. The device for generating processing job 70 searches for at least one candidate Cp for the cutting position on the basis of new fifth layout information 85 instead of the first layout information 81, selects, from among the candidates Cp for the cutting position, a candidate having a small number of cutting positions that can be processed by the first machining device 20 and the second machining device 50 on the basis of the maximum sizes of the sheet front edge margin width Aw1b and the sheet rear edge margin width Aw2b of the margin regions Ar1b and Ar2b between the contour SL1 of the sheet Sh and the contour Pa of the product P in the first direction, which can be discharged by the first machining device 20, and the maximum size and the minimum size of the intermediate sheet Sh1 in the first direction, which can be conveyed by the second machining device 50, and generates a processing job for performing processing at the selected cutting position.
The device for generating processing job 70 generates a processing job in which a cutting position is set between the front end of the sheet Sh and the product P on the most front end side in the first direction. The device for generating processing job 70 can correct skew feeding of the sheet Sh or skew feeding of a print image printed on the sheet Sh by setting the cutting position within the sheet front edge margin width Aw1.
