[Technical field]

[0001] The present invention relates to a sheet processing system that cuts out a product, such as a ticket, printed on a sheet and extracts it from the sheet. [Background technology]

[0002] Conventionally, deliverables such as tickets printed on sheets are cut out from the sheets. There are known sheet processing systems. For example, Patent Document 1 describes a device in which a large-sized sheet on which multiple deliverables (single sheets) are printed is cut by a first processing device (first sheet cutting device), and the reduced-sized processed sheet is cut into individual deliverables by a second processing device (second sheet cutting device). Also, Patent Document 2 discloses a paper stacking device that stacks the usable paper parts cut by a paper cutting device in an aligned state and allows an operator to easily remove them. Specifically, the paper stacking device is equipped with a paper sorting device, and the paper sorting device is configured to determine the position of the paper in the conveying direction by a partition plate and a side plate, and to determine the position perpendicular to the conveying direction by a stopper plate, so that the sorted multiple rows of usable paper parts can be stacked in an aligned state in a predetermined location in sequence.

[0004] For example, in a case where a large-sized sheet on which a product is printed is cut by a first processing device and the reduced-sized processed sheet (at least one intermediate sheet) is cut into individual products by a second processing device, as disclosed in Patent Document 1, in order to sort and stack the cut products in an aligned state, a paper stacking device equipped with a paper sorting device as disclosed in Patent Document 2 is connected to the rear of the device in which the smaller-sized processed sheet (at least one intermediate sheet) is cut into individual products, as disclosed in Patent Document 2, the products discharged from the second processing device are not discharged in the same position relative to the sorting position of the paper stacking device (paper sorting device) between the multiple intermediate sheets created, and it becomes necessary to move the width direction positions of the partition board and side board of the paper sorting device during the work, which is considered to reduce work efficiency. Also, if the products are the same size but are not discharged in the same position relative to the sorting position, it is considered that it is not possible to move while holding the ones already loaded.

Effect of the Invention

[0013] According to the invention described in claim 1, a sheet sorting device that receives single sheets of paper continuously discharged in one or more rows and stacks them in sorting units is connected downstream of the device in which the sheets after cutting processing by the first processing device are cut into individual products by the second processing device, so that the products after cutting processing can be sorted and stacked in an aligned state.

[Figure 9] 11 is a diagram showing processes in a first processing device 320 and the second processing device 350. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a plan view showing an overall configuration of a sheet processing system 1 in the embodiment.

[0022] [Overall configuration of sheet processing system 1] The sheet processing system 1 of this embodiment includes, in order from the upstream side in the conveying direction, a printing device 308, a paper feeding device 310, a first processing device 320, a cross conveyor device 330, an insertion unit 340, a second processing device 350, and a paper sorting device 320. The sheet processing system 1 also includes a processing job generation device 370 that generates processing jobs that are the contents to be processed by the first processing device 320 and the second processing device 350.

[0023] In recent years, the maximum printable sheet size of general-purpose printing machines has tended to become larger. For example, it is becoming increasingly possible to print sizes larger than B3 size. This sheet processing system 1 is configured to accept a sheet S of a certain size or larger that has been printed by a printing device 308, and have the first processing device 20 cut and process the sheet to a sheet size that can be accepted by the second processing device 350, and then hand over the processed sheet to the second processing device 50.

[0024] The second processing device 350 is a general-purpose sheet cutting device that has been commonly used in the market for some time, and the maximum sheet size that can be processed is, for example, B3 size. The first processing device 320 can process sheets of a larger size than the second processing device 350, and can also process sizes exceeding B3 size.

[0025] The printing device 308 prints a product Q on a sheet S based on the layout information. The printed sheet S is transported to the paper feeder 310, and is either transported directly to the first processing device 320 or stored in the paper feeder 310. The printing device 308 is not connected to the paper feeder 310, and the printed sheet S may be transported to the paper feeder 310 by an operator.

[0026] In this embodiment, the sheet feeding device 310 is configured to be able to feed sheets up to a maximum size of B2. The sheet feeding device 310 conveys the sheet S to the first processing device 320, and the sheet S is processed in the first processing device 320 based on the timing when the leading edge of the sheet S reaches the leading edge detection sensor 321 of the first processing device 320.

[0027] The first processing device 320 is installed to perform pre-cutting (primary processing) to a sheet size acceptable to the general-purpose second processing device 350, and has a leading edge detection sensor 321 (321a, 321b) that detects the arrival of the leading edge of the sheet S transported from the sheet feeder 310, and laser sensors 327 (327a, 327b) that detect the leading edge of the sheet S and the position of a registration mark previously given to the sheet S, and detect the inclination angle of the printed image with respect to the sheet transport direction. The leading edge detection sensor 321 and the laser sensor 327 are each disposed at two locations in the width direction perpendicular to the sheet transport direction.

[0028] The first processing device 320 also has an angle adjustment means capable of adjusting the angle of the cutting mechanism 320a of the cross-cut section so that it is perpendicular to the conveying direction of the printed image based on the inclination angle of the printed image detected by the laser sensor 327. The cutting mechanism 320a stops the sheet S at a pre-set cutting position, and then cuts the sheet S by moving a pair of upper and lower rotary blades 320aa in the width direction perpendicular to the conveying direction of the sheet S. The pair of upper and lower rotary blades 320aa of the moving blade unit are arranged opposite to each other on the upper and lower sides via the path along which the sheet S is conveyed. In this way, for example, the first processing device 320 separates the conveyed sheet S into two sheets, an intermediate sheet S1 and an intermediate sheet S2, by cutting the conveyed sheet S at the first cutting position according to the processing job. The two intermediate sheets S1 and S2 are conveyed to the second processing device 350 in a line up front and back. The intermediate sheet S2 may be discharged from the conveying path as an unnecessary margin and discarded. The first cutting position is a cutting line on the sheet S along which the sheet S is cut by the first processing device 320, and may be one or more.

[0029] The cut intermediate sheet S1 is discharged onto the cross conveyor device 330 by a pair of conveying rollers. The discharge of the intermediate sheet S1 is detected by a discharge sensor (not shown). When a guillotine-type cutting blade is used as the cutting blade for pre-cutting (primary processing) the large-sized sheet S, a blade that is long in the width direction of the sheet is required, which can cause problems with warping and distortion. In contrast, if a pair of upper and lower rotary blades that move in the sheet transport direction are used, the problems of warping and distortion are solved, making it suitable for the first processing device 320.

[0030] The cross conveyor device 330 receives the intermediate sheet S1 that has been cut and processed by the first processing device 320 and transported in the first direction, transports it in a second direction intersecting the first direction, and sends it to the second processing device 350. The cross conveyor device 330 is disposed in the rear stage of the first processing device 320, and includes an oblique transport means that receives the intermediate sheet S1 discharged from the first processing device 320 onto an endless belt 331 (a single belt having a predetermined width), and transports the intermediate sheet S1 obliquely toward the guide wall 332 so that the edge of the received intermediate sheet S1 is aligned with the guide wall 332, while transporting the intermediate sheet S1 downstream in the transport direction.

[0031] An insertion unit 340 is disposed downstream of the cross conveyor device 330, which delivers the intermediate sheet S1 discharged from the cross conveyor device 330 to a paper feed port of the second processing device 350. The insertion unit 340 includes an oblique conveying means for conveying the intermediate sheet S1 received by the insertion unit 340 downstream in the conveying direction while conveying the intermediate sheet S1 obliquely toward the guide wall 341 by air suction so that the edge of the intermediate sheet S1 is aligned with the guide wall 341.

[0032] The second processing device 350 is a sheet cutting device that has been widely used in the market for a long time, and the intermediate sheet S1 that has been cut (primarily processed) by the first processing device 320 to a sheet size that the second processing device 350 can accept is delivered from the insertion unit 340 to the paper feed port of the second processing device 350. The intermediate sheet S1 is then sent out in the sheet conveying direction, and the sent out intermediate sheet S1 is cut while being conveyed in the device body based on the contents of the processing job sent from the processing job generating device 370, and the product Q after cutting is discharged from the device body. The second processing device 350 includes a pair of cutting blades 69 (guillotine type blades) that stop the intermediate sheet S1 conveyed in the second direction and cut it in the first direction, and a pair of cutting blades 36 (rotary blades) that cut the intermediate sheet S1 in the second direction while conveying it in the second direction. The sheet S needs to be cut by the rotary blade 320aa of the first processing device 320 so that the intermediate sheet S is equal to or smaller than the maximum size that can be processed by the second processing device 350. When cutting, the rotary blade 320aa of the first processing device 320 stops conveying the sheet S and then moves the rotary blade 320aa in the second direction to cut the sheet S, so processing by the rotary blade 320aa takes time. In contrast, the position of the rotary blade 20 of the second processing device 350 is adjustable in the first direction, and the rotary blade 20 can cut the intermediate sheet S1 while conveying it in the second direction, so that the processing time can be shortened. Therefore, the cutting of the sheet S in the second direction can be shortened by performing it in the second processing device 350 rather than by performing it in the first processing device 320.

[0033] The second processing device 350 performs processing on the intermediate sheet S1, such as perforation, vertical folding, horizontal folding, rolling, etc., in addition to processing the intermediate sheet S1 into the product Q by vertical cutting and horizontal cutting. , embossing, die cutting, vertical folding, horizontal folding, pseudo gluing, bonding or binding The product Q is the product of the sheet S processed by the sheet processing system 1. The result is a single sheet of paper (deliverable), and examples of the result include a ticket with a stub and a flyer with a ticket stub.

[0034] As shown in FIG. 1, the paper sorting device 2 is composed of an accumulation / transport section 91 and a stacker section 92, which are driven independently of each other. The accumulation / transport section 91 receives processed single sheets Q continuously discharged from the second processing device on a placement section 95, stacks them in classification units, and then continuously transfers each of the stacked stacked single sheets Q' downstream. The stacker section 92 is disposed downstream of the accumulation / transport section 91, and continuously stacks the stacked single sheets Q' transferred from the accumulation / transport section 91 at different positions on the placement surface in the conveying direction. The abutment guide 93 regulates the front end of processed single sheets Q discharged in the conveying direction F from the main body of the second processing device 350, so that the front edges of the single sheets Q are aligned when they are loaded on the placement section 95. At that time, the left and right edges in the width direction W perpendicular to the conveying direction F can be aligned using the side guides 961-964. In the embodiment, three rows of processed slip paper Q shown in FIG. 1 are discharged from the device body 1 of the second processing device 350 and received by the placement unit 95.

[0035] [Specific Configuration of Second Processing Device 350] A specific configuration of the second processing device 350 according to the present invention will be described with reference to the drawings. In the following description, the direction perpendicular to the conveying direction F of the conveying section 4 that conveys the sheet S is referred to as the width direction W, and the right side when viewed from the upstream side to the downstream side in the conveying direction F is referred to as the right side of the device, and the left side is referred to as the left side of the device. FIG. 2 is a schematic vertical cross-sectional view of the second processing device 350 according to the present invention. In FIG. 2, the processing device D includes a supply section 3 at the upstream end of the device body of the second processing device 350 in the conveying direction F of the sheet S, and a paper sorting device 2 on which cut-sheet paper Q is placed as a product after processing at the downstream end of the conveying direction F, and a substantially horizontal conveying path 5 is configured between the supply section 3 and the paper sorting device 2.

[0036] The conveying path 5 is provided with a conveying section 4 in which a plurality of pairs of upper and lower conveying rollers 9-17 are installed. The conveying rollers 9-17 are arranged at intervals in the conveying direction F. The conveying rollers 9-17 constituting the conveying section 4 are respectively connected to conveying drive units 41-44 via power transmission mechanisms (not shown), and the conveying drive units 41-44 are electrically connected to a control unit 45.

[0037] The control unit 45 has a built-in CPU and storage devices such as RAM and ROM, and an operation panel 46 and the reading unit 26 are electrically connected to an interface of the control unit 45. The operation panel 46 functions as both a setting unit for setting various processing information including information related to the cutting process of the sheet S, and a display unit. The reading unit 26 also constitutes the setting unit.

[0038] A processing section 24 that processes the sheet S being conveyed is provided on the conveying path 5. In Fig. 2, the processing section 24 includes a cutting section 19 and a crease processing section 21 that forms creases perpendicular to the conveying direction F. The cutting section 19 is composed of three slitter processing sections 20 and a cutter processing section 22.

[0039] The slitter processing section 20, the crease processing section 21, and the cutter processing section 22 are each configured as a detachable unit, and are structured so that they can be attached and detached to desired positions in the device body 1 using a cassette system. Therefore, depending on the type of processing, the arrangement order of the processing sections 20, 21, and 22 can be changed, or they can be replaced with or added to other processing sections 24, such as a mechanism for performing crease processing along the conveying direction F, a chamfering mechanism, or a perforation forming mechanism.

[0040] A reading unit 26 and a reject mechanism 25 are disposed upstream of the slitter processing unit 20, and a trimmings dropping mechanism 27 is disposed downstream of the slitter processing unit 20. In addition, a trimmings collecting unit 23 is disposed at the bottom within the device body 1 of the second processing device 350.

[0041] The conveying path 5 is further provided with a plurality of light-transmitting detectors 31-35 for detecting the leading edge (downstream edge) Sf or trailing edge (upstream edge) Sr of the sheet S, each of which is electrically connected to an interface of the control unit 45. The first detector 31, which is the most upstream detector in the conveying direction F of the sheet S, is disposed between the suction conveying unit 62 of the supply unit 3 and the supply roller 8, the next second detector 32 is disposed near the upstream side of the slitter processing unit 20, the next third detector 33 is disposed midway through the slitter processing unit 20, the next fourth detector 34 is disposed near the upstream side of the crease processing unit 21, and the fifth detector 35, which is the most downstream detector, is disposed near the upstream side of the stacker unit 2.

[0042] The first detection unit 31 detects the leading edge Sf of the sheet S before it is gripped by the supply roller 8 after being suction-conveyed by the suction-conveying unit 62 of the supply unit 3, or the trailing edge Sr of the sheet S after it has been gripped and transported by the supply roller 8, and is used to calculate the position of the sheet S being subsequently transported on the transport path 5 based on the detected position of the sheet S as a reference.

[0043] The second detection unit 32 and the third detection unit 33 detect a jam of the sheet S during processing. The fourth detection unit 34 is installed as an auxiliary unit to correct the sheet position information obtained by the first detection unit 31 to make the sheet position information more accurate in case the transport path 5 becomes longer and a positional deviation (transport error) accumulates in the transport direction F of the sheet S during processing on the transport path 5. The fifth detection unit 35 detects the discharge of the cut slip Q after processing to the paper sorting device 2. The fifth detection unit 35 also detects a jam of the cut slip Q in the paper sorting device 2.

[0044] (Supply section 3) The supply unit 3 includes a supply table 61, supply rollers 8, a suction conveying unit 62, and a separation air blowing unit 63. The supply table 61 is provided to receive sheets S and to supply the sheets S to the conveying path 5. The supply table 61 can be raised and lowered by a lifting means (not shown). When the sheets S are supplied, the lifting means raises the supply table 61 from the standby position to a supply position at a predetermined height where the uppermost sheet S is suction-conveyed by the suction conveying unit 62 and can be supplied to the conveying path 5. Thus, the supply table 61 can move between the standby position and the supply position.

[0045] A pair of upper and lower supply rollers 8 are provided. The suction conveying unit 62 includes a suction fan 67, a conveying belt 64, and a belt roller 65. In the supplying unit 3, a predetermined number of sheets S stacked on a supply table 61 are supplied to the conveying path 5 one by one from the top using the suction conveying unit 62 and the pair of upper and lower supply rollers 8.

[0046] The separation and blowing section 63 blows air toward the leading edge Sf of the sheet S on the supply table 61 using a fan (not shown), separates the uppermost sheet S from the stacked sheets S, and adsorbs and conveys it to the suction conveying section 62. One of the belt rollers 65 and the lower supply roller 81 of the supply rollers 8 are connected to the paper feed drive section 47. The separation and blowing section 63, the suction fan 67, and the paper feed drive section 47 are electrically connected to the control section 45.

[0047] (Reading unit 26) The reading unit 26 reads an image of a position mark M1 printed on the leading corner of the sheet S as shown in Fig. 3, and detects the reference position for processing in the conveying direction F of the sheet S and in the width direction W perpendicular to the conveying direction F. The reading unit 26 can also be configured as a setting unit that automatically reads and sets processing information, separate from the manual input of various processing information through the operation panel 46. Specifically, the reading unit 26 reads an image of a barcode M2 ​​printed on the leading edge of the sheet S as shown in Fig. 3, and obtains various processing information to be applied to the sheet S. The reading unit 26 is configured with a CCD sensor or the like.

[0048] (Reject mechanism 25) The reject mechanism 25 in FIG. 2 is activated when the position mark M1 or barcode M2 ​​printed on the sheet S is unclear and cannot be read by the reading unit 26, causing the unreadable sheet S to fall and be collected in the tray 25a.

[0049] (Slitter processing section 20) The slitter processing section 20 has three units arranged in the conveying direction F, and each unit has two sets of cutting blades 36 consisting of upper and lower rotary cutting blades arranged at an interval in the width direction W. The cutting blades 36 are installed movably in a direction intersecting the conveying direction F of the conveying section 4, and constitute processing members that perform a predetermined processing at a predetermined position of the conveyed sheet S. The driving force of the rotation driving section 48, which serves as a processing member driving section that drives the processing members, rotates either the upper or lower cutting blade 36 on the conveying path 5, and the other cutting blade 36 is driven to rotate, thereby cutting the sheet S along the conveying direction F by the conveying section 4 and forming a cutting line T on the sheet S.

[0050] (Crease processing section 21) The crease processing unit 21 includes a lower die 39 having a concave portion at the upper end and an upper die 38 having a convex portion at the lower end that fits into the concave portion, and the upper die 38 is connected to a folding die drive unit 49 such as a motor via a power transmission mechanism. That is, the upper die 38 is lowered by the driving force of the folding die drive unit 49 to form a crease in the sheet S in the width direction W perpendicular to the conveying direction F.

[0051] (Cutter processing section 22) The cutter processing section 22 extends in the width direction W and includes a pair of opposing cutting blades 69. One cutting blade 69 is composed of an upper movable blade 71, and the other cutting blade 69 is composed of a lower fixed blade 73. The upper movable blade 71 comes into contact with and separates from the lower fixed blade 73 to cut the sheet S in the width direction W perpendicular to the conveying direction F, and form a cutting line K on the sheet S. The upper movable blade 71 is connected to a cutting drive section 50 such as a motor via a power transmission mechanism.

[0052] (Cutting waste collection section 23) The trimmings collection section 23 includes a trimmings storage box 54 and guides 59, 60. The trimmings storage box 54 is formed in a rectangular parallelepiped shape with an opening at the top. The trimmings storage box 54 collects and stores the trimmings J that have been cut off in the cutting section 19 and are no longer needed. The guides 59, 60 guide the trimmings J that have been cut off in the cutting section 19 and fall to the trimmings storage box 54.

[0053] (Paper sorting device 2) The paper sorting device 2 is composed of an accumulation / transport section 91 and a stacker section 92. The accumulation / transport section 91 receives the cut sheets Q as the product of the processing process continuously discharged from the main body of the second processing device 350, stacks them in classification units, and then continuously transports each of the stacked cut sheets Q' downstream. The cut sheets Q stacked in classification units are hereinafter referred to as the stacked cut sheets Q'. The stacker section 92 is disposed downstream of the accumulation / transport section 91, and continuously stacks the stacked cut sheets Q' transferred from the accumulation / transport section 91 at different positions on the loading surface in the transport direction. More specifically, the accumulation / transport section 91 is provided with transport rollers that load the stacked cut sheets Q' on a plurality of rotating rollers 94 (drive rollers). The stacker section 92 is provided with a loading section 83 that can load the stacked cut sheets Q' at different positions on the loading surface. The placement section 83 is provided with a belt conveyor 86 that places the stacked cut sheets Q' on a circulating belt 85. The stacked cut sheets Q' transferred from the accumulation transfer section 91 are placed on the belt conveyor 86 while being conveyed.

[0054] The accumulation / transport section 91 and the stacker section 92 are driven independently of each other to transport the loaded single-sheet paper Q'. The roller drive section 40 is electrically connected to the control section 45, and the control section 45 controls the drive amount of the roller drive section 40, thereby adjusting the rollers 94 to run at a predetermined speed. In addition, the conveyor drive section 51 is electrically connected to the control section 45, and the control section 45 controls the drive amount of the conveyor drive section 51, thereby adjusting the belt conveyor 86 to run at a predetermined speed.

[0055] The specific configuration and operation of the paper sorting device 2 will be described later.

[0056] (Control unit 45) The control unit 45 controls the overall operation of the second processing device 350. The control unit 45 acquires information from the detection units 31 to 35, and controls the driving of the supply unit 3, the conveyance unit 4, the paper sorting device 2, and each processing unit 24 based on processing information for the sheet S set by the operation panel 46 or the reading unit 26, thereby processing the sheet S. When the second processing device 350 is incorporated in the sheet processing system 1, processing is performed based on a generated processing job, which will be described later.

[0057] [Sheet processing pattern] 3 is a plan view showing an example of a processing pattern for a sheet S. The processing pattern shown in the figure is for producing a plurality of cut sheets Q from one sheet S. Cutting lines T as a plurality of processing lines extending parallel to the conveying direction F and cutting lines K as a plurality of processing lines extending in the width direction W perpendicular to the conveying direction F are set.

[0058] The first cutting lines T1 and T6 shown at the right and left ends in FIG. 3 are formed by the unit 20a installed at the most upstream of the slitter processing unit 20 on the conveying path 5 in FIG. 2. The second and fifth cutting lines T2 and T5 formed on the inside of the first cutting line T1 and the sixth cutting line T6, respectively, are formed by the central unit 20b in the conveying direction F. The third and fourth cutting lines T3 and T4 formed further inside the second cutting line T2 and the fifth cutting line T5 are formed by the unit 20c installed at the most downstream in the conveying direction F. The unnecessary strip-shaped cutting waste Jb between the second cutting line T2 and the third cutting line T3 and between the fourth cutting line T4 and the fifth cutting line T5 is guided downward by the cutting waste dropping mechanism 27 shown in FIG. 2 and collected by the cutting waste collecting unit 23.

[0059] In addition, the cutting line K is formed by cutting the sheet S parallel to the conveying direction F at cutting lines T1 to T6 and removing the long cutting scraps J cut from the sheet S, thereby simultaneously performing multiple cutting processes on multiple strip-shaped cut pieces aligned in the width direction W.

[0060] In the processing pattern of the sheet S shown in Figure 3, since no fold lines are set by the crease processing unit 21, in the processing unit 24 illustrated in Figure 2, the crease processing unit 21 is left received in the receiving unit 6 and is not functioning, so that crease processing is not performed, or it is replaced with a conveying processing unit not shown, or the crease processing unit 21 is detached from the receiving unit 6 and used in an empty state.

[0061] Various processing information to be applied to sheets S for the arrangement pattern of cut slips Q after such processing is set by the user using operation panel 46 or recorded in barcode M2 ​​of sheet S. This various processing information includes information about sheet S itself, such as the length in specific directions such as the transport direction length and width direction length of sheet S, thickness, type, etc.; information about cut slips Q, such as the arrangement, number and dimensions of cut slips Q, and information about the processing of sheets S, such as the size and number of unnecessary cutting scraps J to be cut from sheet S and information about the sorting of cut slips Q. The information about sorting includes sorting necessity information about whether or not to perform sorting in paper sorting device 2, sorting timing information about when to perform sorting, sorting distance information about the distance between cut slips Q sorted one after the other in stacking section 83, sorting stacking information about the stacking method of cut slips Q to be sorted, such as the overlap length between preceding and succeeding cut slips Q, and sorting notification information about whether to notify by light or sound when sorting.

[0062] Once the setting of the processing information has been completed, it can be stored in the storage device of the control unit 45. By assigning a number, a processing name, a name, etc. to each of a plurality of different processing information such as the arrangement pattern of cut slips Q after processing of sheets S and storing them in the storage device, the user can operate the operation panel 46 as the operation unit to call up the processing information relating to the required processing content from the storage device and process sheets S.

[0063] [Configuration of Paper Separator 2] Next, a specific configuration of the paper sorting device 2 will be described with reference to FIG.

[0064] As shown in FIG. 4, the paper sorting device 2 is composed of an accumulation / transport section 91 and a stacker section 92, which are driven independently of each other. The accumulation / transport section 91 receives processed cut sheets Q continuously discharged from the main body of the second processing device 350 at a placement section 95, stacks the processed cut sheets Q in classification units, and then continuously transfers each of the stacked cut sheets Q' downstream. The stacker section 92 is disposed downstream of the accumulation / transport section 91, and continuously stacks the stacked cut sheets Q' transferred from the accumulation / transport section 91 at different positions on the placement surface in the conveying direction. More specifically, the accumulation / transport section 91 is provided with conveying rollers that load the cut sheets Q' on a plurality of rotating rollers 94 (drive rollers). The stacker section 92 is provided with a placement section 83 that can load the stacked cut sheets Q' at different positions on the placement surface. The placement section 83 is provided with a belt conveyor 86 that places the stacked cut sheets Q' on a circulating belt 85. The stacked cut sheets Q' transferred from the accumulation transfer section 91 are placed on the belt conveyor 86 while being conveyed.

[0065] The belt conveyor 86 in the stacker unit 92 includes an endless belt 85, conveyor rollers 87, and a conveyor drive unit 51. The conveyor rollers 87 are installed at three locations spaced a predetermined distance apart in the discharge direction of the stacked cut sheets Q', which is the same direction as the conveyance direction F of the sheets S, and the belt 85 is stretched over the conveyor rollers 87. The conveyor drive unit 51 is a drive mechanism for rotating the endless belt 85 to transport the stacked cut sheets Q' after sorting processing downstream in the paper conveyance direction F, and includes a drive motor 101 that functions as a drive means, a pulley 511 attached to the rotating shaft of the drive motor 101, a pulley 512 attached to the rotating shaft 513 of the conveyor roller 87, and a timing belt 514 stretched between these pulleys 511 and 512. When the drive motor 101 is driven to rotate, the driving force is transmitted to the rotary shaft 513 of the conveyor roller 87 via the pulleys 511 and 512, so that the conveyor roller 87 rotates, causing the endless belt 85 to rotate.

[0066] Next, a description will be given of the configuration of the accumulation / transport section 91. As shown in Fig. 4, the accumulation / transport section 91 is made up of a placement section 95 that receives processed slips Q that are continuously discharged from the device main body 1 (processing section), and a plurality of rollers 94 (drive rollers) that serve as transport rollers that stack the received slips Q in sections in the transport width direction and then continuously transport them to the stacker section 92.

[0067] The abutment guide 93 and side guides 961-964 in the placement section 95 are driven by a guide drive section 52, and the multiple rollers 94 are driven by a roller drive section 40. Both drive sections are electrically connected to a control section 45, which controls the drive amount to adjust each guide position. The guide drive section 52 includes a motor 103 for driving the abutment guide 93 in the up-down direction, a motor 102 for driving it in the front-rear direction in the conveying direction F, and motors 104-105 for driving the side guides 961-964 in the left-right direction in the conveying width direction. The roller drive section 40 includes a motor 108 for driving the multiple rollers 94 to rotate.

[0068] The abutment guide 93 regulates the leading edge of processed slips Q that are discharged in the transport direction F from the device body of the second processing section 350, so that the leading edges of the slips Q are aligned when stacked on the stacking section 95. At that time, the side guides 961-964 can be used to align the left and right edges in the width direction W perpendicular to the transport direction F. Note that the embodiment illustrates a case in which three rows of processed slips Q shown in Figure 3 are discharged from the device body 1 and received by the stacking section 95.

[0069] FIG. 4 shows a state in which the abutment guide 93 advances downward relative to the transport path when the cut sheets Q are stacked, and when the stacked stack of cut sheets Q' is transported downstream, the abutment guide 93 retreats upward relative to the transport path.

[0070] [Sorting operation of paper sorting device 2]

[0071] The paper sorting device 2 is composed of an accumulation / transport section 91 and a stacker section 92, and the processed single slips Q discharged from the second processing device 350 are first received by the loading section 95 of the accumulation / transport section 91 and stacked in sorting units, and then each stacked stack of single slips Q' is continuously transported to the stacker section 92 located downstream. In this embodiment, the accumulation / transport section 91 is provided with transport rollers that load the stack of single slips Q' on a plurality of rotating rollers 94. Note that the accumulation / transport section 91 may be configured to be provided with a belt conveyor 88 that loads the stack of single slips Q' on a circulating belt, instead of the plurality of rollers 94.

[0072] The stacker unit 92 continuously stacks the loaded single cut paper Q' transferred from the accumulation and transfer unit 91 at different positions on the placement surface 83. The control unit 45 controls the loading of single cut paper Q' transferred to the stacker unit 92 by the accumulation and transfer unit 91 so that a specified gap is formed between the loaded single cut paper Q' transferred first and the succeeding loaded single cut paper Q'. The stacker unit is provided with a belt conveyor 86 that loads the loaded single cut paper Q' on a circulating belt.

[0073] The accumulation and transfer section 91 is capable of loading multiple single slip papers Q' in the transport direction, and in the accumulation and transfer section 91, the control section 45 at least receives the single slip papers Q in a stopped transport state when the single slip papers Q are stacked, stacks them in sections, and then accumulates the stacked single slip papers Q' in stages while shifting and transferring them while stopping along the way, and controls the accumulated stack of single slip papers Q' to be transferred in stages from the accumulated stack of single slip papers Q' to the stacker section 92.

[0074] According to the above, the efficiency of the sorting operation can be improved.

[0075] Next, a specific embodiment will be given to explain the sorting operation of the paper sorting device 2. Figures 5 and 6 are schematic diagrams showing the sorting operation of the paper sorting device 2. Note that side guides 961 to 964 are omitted in Figures 5 and 6.

[0076] The sorting operation of the paper sorting device 2 in this embodiment describes a series of sorting operations in the conveying direction when a sheet S having the processing pattern shown in Figure 3 is discharged from the second processing device 350 as a single sheet of paper Q after processing.

[0077] (1) As shown in Figure 5(a), processed slips Q are continuously discharged from the transport rollers 17 of the second processing device 350 toward the loading section 95 of the accumulation and transfer section 91, and the slips Q are stacked in a state where they are aligned by the abutment guide 93 and side guides 961-964. The number of slips Q discharged from the device body 1 is counted by the fifth detection section 35.

[0078] (2) Next, after the number of cut sheets Q loaded on the loading section 95 reaches the sorting number (sorting unit), as shown in Figure 5(b), the abutment guide 93 is retracted upward, and then the roller drive section 40 rotates the multiple rollers 94 to move the stacked cut sheets Q'1 downstream a predetermined distance (roughly the length of the cut sheets Q in the transport direction plus the thickness of the abutment guide 93), and the rotation is stopped. At this time, the discharge of cut sheets Q from the transport rollers 17 of the device body 1 is stopped.

[0079] (3) Next, as shown in FIG. 5(c), after the abutment guide 93 has again advanced downward relative to the conveyance path, the discharge of the cut sheets Q from the conveyance rollers 17 of the device body 1 is resumed.

[0080] (4) Next, after the number of cut sheets Q loaded on the loading section 95 reaches the division number (division unit), 5(d), after the abutment guide 93 is retracted upward, the roller drive unit 40 rotates the rollers 94 to move the stacked cut sheets Q'1, Q'2 downstream a predetermined distance, and the rotation is stopped. At this time, the discharge of cut sheets Q from the transport rollers 17 of the second processing device 350 is stopped.

[0081] (5) Next, as shown in FIG. 6(e), after the abutment guide 93 again advances downward relative to the conveying path, the discharge of the cut sheets Q from the conveying rollers 17 of the second processing device 350 is resumed.

[0082] (6) Next, after the number of cut sheets Q loaded on the loading section 95 reaches the division number (division unit), As shown in FIG. 6(f), after the abutment guide 93 is retracted upward, the roller drive unit 40 drives and rotates the rollers 94 to transfer the stacked single slips Q'1, Q'2, and Q'3 downstream a predetermined distance, and then the rotation is stopped. At this time, only Q'1 is delivered from the accumulation and transfer unit 91 to the placement unit 83 (belt conveyor 86) of the stacker unit 92. The conveyor drive unit 51 drives and rotates the belt conveyor 86 when transferring the stacked single slips Q'1, Q'2, and Q'3, and stops after delivering the stacked single slips Q'1 from the accumulation and transfer unit 91 to the stacker unit 92. At this time, the discharge of single slips Q from the transport rollers 17 of the device main body 1 is stopped.

[0083] (7) Next, as shown in FIG. 6(g), after the abutment guide 93 again advances downward relative to the conveying path, the discharge of the cut sheets Q from the conveying rollers 17 of the second processing device 350 is resumed.

[0084] (8) Next, after the number of cut sheets Q loaded on the loading section 95 reaches the division number (division unit), As shown in FIG. 6(h), after the abutment guide 93 is retracted upward, the roller drive unit 40 drives and rotates the rollers 94 to transfer the stacked single slips Q'2, Q'3, and Q'4 downstream a predetermined distance, and then stops the rotation. At this time, only Q'2 is delivered from the accumulation and transfer unit 91 to the placement unit 83 (belt conveyor 86) of the stacker unit 92. The conveyor drive unit 51 drives and rotates the belt conveyor 86 while transferring the stacked single slips Q'2, Q'3, and Q'4, and stops after delivering the stacked single slips Q'2 from the accumulation and transfer unit 91 to the stacker unit 92. At this time, the discharge of single slips Q from the transport rollers 17 of the second processing device 350 is stopped.

[0085] The integrated transfer unit 91 and the stacker unit 92 are configured to be independently driven from each other. The gap X1 between the single-sheet papers Q' stacked on the integrated transfer unit 91 and the gap X2 between the single-sheet papers Q' stacked on the stacker unit 92 are specially controlled by the roller drive unit 40 and the conveyor drive unit 51 via the control unit 45. Regarding X1, it is generally a gap obtained by adding a margin for the smooth forward and backward movement of the abutting guide 93 to the thickness of the abutting guide 93, and a gap of about 10 mm may be sufficient. Regarding X2, it is a gap necessary for easy extraction when the operator takes out the single-sheet papers stacked on the belt conveyor, and a gap of about 20 mm to 50 mm is a guideline. The two have a relationship of X1 < X2, and the conveyance speeds V1 and V2 of the single-sheet papers Q' stacked on the integrated transfer unit 91 and the stacker unit 92 also have a relationship of V1 < V2. That is, when delivering (shifting and transferring) the single-sheet papers Q' from the integrated transfer unit 91 to the stacker unit 92, control is performed to accelerate the conveyance speed and widen the gap from X1 to X2. In the embodiment, the number of single-sheet papers Q' arranged on the integrated transfer unit 91 has been described as three, but it is not limited to this, and it may be one or three or more. Also, the number of single-sheet papers Q' arranged on the stacker unit 92 has been described as two, but it is not limited to this, and it may be one or two or more.

[0086] [Configuration of the processing job generation device 370] Next, the processing job generation device 370 will be described in detail with reference to FIG. 7. The processing job generation device 370 includes a layout information creation unit 371, a processing position search unit 373, a determination unit 375, a processing job generation unit 377, and a storage unit 379.

[0087] The layout information creation unit 371 divides the layout of the sheet S into one or more intermediate sheets according to a predetermined procedure based on the respective longitudinal and lateral sizes of the product Q, the size of the sheet S on which the product Q is printed, and processing conditions such as the number of impositions and margin settings, and creates layout information that arranges the product Q. When creating the layout information, the arrangement of the product Q takes into consideration the sorting position in the sheet sorting device, and the product Q discharged to the same sorting position is arranged so that the distance from the cutting line of the intermediate sheet to the product is the same.

[0088] The layout information creating unit 371 copies the result Q, and sets the position of the copied result Q based on the size of the result Q, thereby imposing the result Q and creating layout information.

[0089] The processing position search unit 373 has a cutting position candidate search unit 373a that searches for candidates for the first cutting position where cutting is performed by the first processing device 320, and a cutting position candidate selection unit 373b that selects an appropriate candidate from the searched cutting position candidates.

[0090] The cutting position candidate searching unit 373a searches for candidates for the first cutting position where cutting is performed by the first processing device 320 based on the layout information, under the following conditions.

[0091] The determination unit 375 determines whether the first processing device 320 can cut at the candidate for the first cutting position searched for by the processing position search unit 373. Also, the determination unit 375 determines whether the intermediate sheet S1 cut and divided at the first cutting position can be transported by the second processing device 350. If both of the determination results are possible, the determination unit 375 determines that the searched candidate is processable, and if at least one of the both determination results is not possible, the determination unit 375 determines that the searched candidate is not processable.

[0092] The processing job generating unit 377 generates processing jobs for processing by the first processing device 320 and the second processing device 350, based on the candidates for the first cutting position that the determining unit 375 has determined to be processable.

[0093] The output unit of the processing job generating unit 377 has a data output unit (not shown). The data output unit outputs data of the processing job generated by the processing job generating unit 377 to the first processing device 320 and the second processing device 350. Since the data of the processing job generated by the processing job generating unit 377 is composed of processing data for the first processing device 320 and processing data for the second processing device 350, the data output unit outputs the processing data for the first processing device 320 to the first processing device 320 and the processing data for the second processing device 350 to the second processing device 350.

[0094] The processing job includes the size and type of sheet, the size of the deliverables and the number of sheets on the sheet. This information includes the layout, position, type, number and dimensions of the processing applied to the sheet. The information included in the work job may be only the information on the processing position, or may be the information on the processing position and the processing It may be a combination of types, a combination of processing positions and arrangement of products, or a combination of processing It may be a combination of information on the process location, the process type, and the layout of the deliverables.

[0095] The storage unit 379 is composed of at least one of a ROM, a RAM, a HDD, and an SSD, and stores programs or data required for generating a processing job. Information on the product to be printed is stored, for example, in the storage unit 379 or an external device (not shown). The external device is, for example, a personal computer, a smartphone, or a tablet PC. The processing job generating device 370 is connected to the processing job generating device 370 via a network.

[0096] The layout information creation unit 371, the processing position search unit 373, the judgment unit 375, and the processing job generation unit 377 are each composed of one or more integrated circuits, for example, a CPU or an FPGA, and each function is realized by the integrated circuits reading out data and programs stored in the memory unit 379 and performing various arithmetic processing.

[0097] [Operation of the modification job generating device 370] Next, the operation of the above-mentioned modification job generating device 370 will be described with reference to the flowchart of FIG.

[0098] First, a user inputs processing conditions through a processing condition input unit (not shown) (step 1). The processing conditions include the size of the sheet S, the size of the product Q, and the types of processing in the first processing device and the second processing device.

[0099] Next, the layout information creation unit 371 creates layout information based on the input processing conditions (step 2). The layout information includes information regarding the position of the product Q to be placed on the sheet and the following cutting position information, and the product Q is placed on the divided intermediate sheet. Since the sheet processing system 1 is configured such that the first processing device 320 cuts the sheet to a sheet size (e.g., B3 size) that the second processing device 350 can accept, and then passes the processed sheet to the second processing device 350, multiple intermediate sheets are generated by cutting at least one first cutting position.

[0100] In addition, the layout information is created based on the type of product Q for each section divided in the placement section 95 so that the product Q discharged from the second processing device 350 is discharged to the same dividing position (951, 952, 953) on the placement section 95.

[0101] In addition, the layout information is created on the assumption that when processing the resultant product Q, processing will be carried out continuously between multiple intermediate sheets without changing the installation position of the cutting means in the second processing device 350 and the widthwise position of the side guides.

[0102] Also, as shown in FIG. 9, cutting processing lines 1 and 2 corresponding to the sheet transport reference line in the second processing device 350 are set for each of the multiple intermediate sheets to be divided in the layout information, and the cutting processing lines are set to be the same (X1=X2) so that at least the distances X1 and X2 to one end of the first product closest to the cutting processing lines are positioned at the first division position (951) of the loading section 95.

[0103] Next, based on the layout information, the cutting position candidate searching unit 373a in the processing position searching unit 373 searches for candidates for the first cutting position where cutting is performed by the first processing device 320. Then, the cutting position candidate selecting unit 373b selects an appropriate candidate from the searched cutting position candidates (step 3).

[0104] Next, the determination unit 375 determines whether the first processing device 320 can cut at the candidate for the first cutting position searched for by the processing position search unit 373. It also determines whether the intermediate sheets S1, S2 cut and divided at the first cutting position can be transported by the second processing device 350. If at least one of the two determination results is not possible (step 4; N), it determines that the searched candidate is not processable, and returns to step 3 to select another candidate. Note that if it is determined that all candidates are not processable, the process may be configured to return to step 1. Furthermore, if both judgment results are possible (step 4; Y), the judgment unit 375 judges that the searched candidates can be processed, and the processing job generation unit 377 generates a processing job to be processed by the first processing device 320 and the second processing device 350 based on the candidate for the first cutting position (layout information) that the judgment unit 375 judges to be processable (step 5).

[0105] Next, an output unit (not shown) of the processing job generating unit 377 outputs the processing data generated by the processing job generating unit 377 for the first processing device 1320 to the first processing device 320, and outputs the processing data for the second processing device 350 to the second processing device 350 (step 6). At the same time, the position of the side guide is moved by the guide driving unit based on the processing data.

[0106] [Cutting process of sheet processing system 1] For example, a sheet S on which layout information as shown in FIG. 9(a) is printed is processed in the first processing device 320 and the second processing device 350 as follows, based on a processing job.

[0107] In the first processing device 320, the sheet S is first cut by the processing machine 320a along a cutting processing line 2 corresponding to the sheet conveyance reference line in the second processing device 350, and a margin portion S3 is discarded. Next, the sheet S is cut by the processing machine 320a along a cutting processing line 1 corresponding to the sheet conveyance reference line in the second processing device 350, and two intermediate sheet pieces S1 and S2 are obtained. This is because, as described above, the first processing device 320 cuts the sheet S to a sheet size acceptable to the second processing device 350, and then the processed sheet is handed over to the second processing device 350.

[0108] At that time, as shown in FIG. 9(a), the first products (the product Q1 row in the sheet piece S1 and the product Q1 row in the sheet piece S2) adjacent to the cutting process line 1 and the cutting process line 2, respectively, are processed so that the distances to one end of each are equal to each other (X1=X2), and the two sheet pieces S1 and S2 as intermediate sheets are lined up front and back and sequentially transported to the second processing device 350.

[0109] At the same time, the cutting process lines 1 and 2 are set so that at least the distance (X1, X2) to one end of the first product adjacent to each of the cutting process lines 1 and 2 is positioned at the first sorting position 951 of the placement unit 95 in the paper sorting device 2. When there is a row of second products (Q2) following the row of first products (Q1), such as the sheet S2, the interval between the row of first products (Q1) and the row of second products (Q2) is set by the layout information so that they are positioned at the second sorting position (952) of the placement unit 95. The same applies to the case where there is a row of third products (Q3). The number of sorting positions is not limited to three in the embodiment and may be increased as appropriate.

[0110] Before and after the preceding sheet piece S1 reaches the second processing device 350, the second processing device 350 performs preparations for processing the sheet piece S1 (intermediate sheet). Specifically, the cutting section 19 (slitter processing section 20) of the second processing device 350 is moved to a processing position, and the side guide of the stacking section 95 of the sheet sorting device 2 is moved to a processing position for the sheet piece S1 by the guide driving section 52. At the same time, the stacking section side guide of the sheet sorting device 2 may be moved to a processing position for the sheet piece S2. Also, the processing position of the cutting section 19 (slitter processing section 20) of the second processing device 350 for the sheet piece S2 may be moved to a processing position that is not affected by the processing of the sheet piece S1.

[0111] Next, as shown in FIG. 9(c), in the second processing device 350, the sheet piece S1 is cut along lines 3, 3 by the cutting section 19 (slitter processing section 20), and cut along lines 5, 6, 7, 8, 9, 10 by the cutter processing section 22, and the row of products Q1 is discharged from the second sheet processing device 3 to the loading section 95 of the paper sorting device 2, and loaded on the loading section (951) based on the type of product for each section.

[0112] Before the succeeding sheet piece S2 reaches the second processing device 350, preparations for processing the sheet piece S2 (intermediate sheet) are made in the second processing device 350. Specifically, the cutting means of the second processing device 350 is moved to the processing position, and the side guide of the loading section 95 of the sheet sorting device 2 is moved by the guide driving section 52 to the processing position for the sheet piece S2.

[0113] Next, as shown in Fig. 9(b), the sheet piece S2 is similarly cut by the cutting section 19 (slitter processing section 20) along lines 3, 3, and 4, 4 in the second processing device 350, and cut by the cutter processing section 22 along lines 5, 6, 7, 8, 9, and 10, and the rows of deliverables Q1 and Q2 are discharged from the second processing device 350 to the placement sections (951, 952) of the paper sorting device 2, and are sorted and stacked on the placement sections based on the types of deliverables (Q1, Q2) for each section (951, 952). That is, the row of deliverables Q1 is stacked on the placement section (951), and the row of deliverables Q2 is stacked on the placement section (952).

[0114] According to the above, when a sheet is divided into a plurality of intermediate sheets, the processing job generation device 370 creates layout information based on the type of product for each section divided on the loading unit 95 so that the product Q discharged from the second processing device 350 is discharged to the same sorting position as the sorting position of the loading unit 95, and the guide position control means adjusts the position of the side guide based on the layout information, so that the product types can be sorted and stacked in an aligned state in sorting units regardless of the type of intermediate sheet.

[0115] In addition, the layout information is created on the assumption that the intermediate sheets will be continuously processed without changing the installation position of the cutting means in the second processing device and the width direction position of the side guides during processing of the finished product, so that the processing can be continuously performed based on the layout information, thereby improving the work efficiency.

[0116] In addition, a cutting line corresponding to the sheet conveyance reference line in the second processing device 350 is set for each of the intermediate sheets to be divided in the layout information, and the cutting line is set so that at least the distance to one end of the first product adjacent to the cutting line is positioned at the first division position of the placement unit, so that processing can be performed continuously based on the layout information.
