Description

  The present invention relates to a sheet processing apparatus.

  For a large amount of high-speed printing, continuous paper wound up in a roll is used. In this continuous paper processing system, a continuous paper is supplied from a supply device to a printing machine or a printer (including a rotary press or a digital printer), and the printed continuous paper is conveyed to a paper processing device to be a predetermined paper size. Or a continuous paper printed by a printing machine or printer device once rolled into a roll and then fed (conveyed) to the paper processing device and cut into a predetermined paper size and so on.

In a paper processing apparatus that performs cutting processing of continuous paper, the continuous paper is cut in a transport direction and a width direction (a direction orthogonal to the transport direction) to obtain a predetermined paper size. Cutting continuous paper requires cutting the paper to a predetermined size while transporting the continuous paper at a high speed, so the paper is cut along the transport direction of the continuous paper with a slitter to cut the continuous paper in the width direction. There is an apparatus (for example, patent document 1 etc.) which performs this with a rotary cutter. However, since the rotary cutter cuts continuous paper at full width, it cannot be used when cutting continuous paper partially in the width direction. For this reason, when partially cutting the continuous paper in the width direction, it is necessary to temporarily stop the conveyance of the continuous paper and insert a slitter from the end of the continuous paper in the width direction.

(First embodiment)
Hereinafter, a first embodiment as an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall configuration diagram of a sheet processing system 12 to which the sheet processing apparatus 150 of the first embodiment is applied. The paper processing device 150 is a device that performs a desired process on the continuous paper P being conveyed.

  On the upstream side of the paper processing system 12 in the conveyance direction (arrow E direction) of the continuous paper P (hereinafter, sometimes simply referred to as “upstream side”), the continuous paper P wound in a roll is sequentially unwound. A paper supply device 14 is provided.

  On the downstream side of the continuous paper feeding device 14 in the transport direction E of the continuous paper P (hereinafter sometimes simply referred to as “downstream side”), a paper buffer mechanism 16 is provided, which is alternately arranged up and down. The continuous paper P is conveyed in a state where the continuous paper P is wound around the roller 18 provided.

  The roller 18 positioned below the paper buffer mechanism 16 is movable up and down. Thereby, the tension applied to the continuous paper P is adjusted, and the trouble that the continuous paper P is pulled and cut or the continuous paper P is loosened and bent is prevented.

  A paper processing device 150, which will be described in detail later, is disposed on the downstream side of the paper buffer mechanism 16, and performs desired processing on the conveyed continuous paper P. Note that one of the processes performed on the continuous paper P by the paper processing apparatus 150 is a cutting process for cutting the continuous paper P. For this reason, the continuous paper P can be cut into a desired paper size.

  On the downstream side of the paper processing device 150, a paper guide device 24 for guiding the cut paper P 'to the paper stack 26, the paper stack 28, etc. is provided. Also, a waste paper storage box (not shown) is provided between the paper processing device 150 and the paper guide device 24 for storing unnecessary portions when the continuous paper P is cut when the continuous paper P is cut. . As a result, an unnecessary portion that appears when the continuous paper P is cut is stored in the waste paper storage box, and the cut paper P ′ is guided to the paper stack 26 and the paper stack 28 by the paper guide device 24. In this embodiment, two paper stacks are provided. However, the present invention is not limited to this structure, and three or more paper stacks may be provided.

<Paper handling device>
Next, the sheet processing apparatus 150 will be described in detail. As shown in FIGS. 1 and 2, the sheet processing apparatus 150 includes a drum 160 as a cylindrical body on the conveyance path of the continuous paper P. The drum 160 passes through a rotating shaft 164 supported at both ends by a shaft plate. The drum 160 is rotated by rotating the rotating shaft 164 by a driving force (rotational force) of a driving motor 162 as a driving means. Further, the continuous paper P fed from the nipping and conveying roller 30 provided on the upstream side in the conveyance direction E from the drum 160 is wound around the outer peripheral surface 160A and conveyed to the drum 160 on the downstream side in the conveyance direction E. It has come to be.

  Although details will be described later, a cutting machine 210 for cutting the continuous paper P, a crease line forming machine 220 for forming (processing) a crease line on the continuous paper P, and punch holes in the continuous paper P (processing). ) And a perforation forming machine 240 for forming (processing) perforations on the continuous paper P are accommodated inside the drum 160 in a state of being installed on the rotary shaft 164.

  Further, slits 166 extending along the rotation axis direction of drum 160 (direction orthogonal to the conveyance direction of continuous paper P) are spaced apart in the circumferential direction (circumferential direction of drum 160) on outer peripheral surface 160A of drum 160. Is provided. The slit 166 is set such that the length in the direction orthogonal to the transport direction (slit width) is longer than the length in the width direction of the continuous paper P (width of the continuous paper P). In the present embodiment, four slits 166 are provided at equal intervals in the circumferential direction of the drum 160 (hereinafter referred to as slits 166A, 166B, 166C, and 166D). As shown in FIGS. 1 to 3, the width of the slit 166 </ b> A described above is large enough to pass a cutting blade 212 (details will be described later) of the cutting machine 210, and the width of the slit 166 </ b> B is a crease line. The width of the slit 166C is large enough to pass the punch hole blade 232 (details will be described later) of the punching machine 230. The width of the slit 166D is large enough to pass a perforation blade 242 (details will be described later) of the perforation forming machine 240.

(Cutting machine)
As shown in FIGS. 4 and 5, the cutting machine 210 includes a trapezoidal screw 213 extending along the rotation axis direction of the drum 160. The trapezoidal screw 213 is rotatably supported by a bearing 214 having one end 213A provided in the drum 160 and fixed to the rotary shaft 164. Further, the other end 213 </ b> B of the trapezoidal screw 213 is connected to a rotary movement motor 215 provided inside the drum 160 and fixed to the rotary shaft 164. When the rotational movement motor 215 is driven (rotated), the trapezoidal screw 213 is also rotated. Further, a support block 216 formed with a female screw portion 216A corresponding to the male screw portion 213C is screwed into the male screw portion 213C of the trapezoidal screw 213. A columnar guide bar 217 that is arranged in parallel to the trapezoidal screw 213 and has both ends fixed to the rotation shaft passes through the base of the support block 216. For this reason, when the rotational movement motor 215 is driven, the trapezoidal screw 213 rotates and the support block 216 moves along the guide bar 217. Note that the moving direction of the support block 216 is switched depending on the rotation direction of the trapezoidal screw 213.

  The support block 216 is provided with a solenoid 218. The solenoid 218 includes a solenoid coil (not shown) and an iron core 218A that reciprocates around the center of the solenoid coil. When the solenoid 218 (solenoid coil) is energized, the iron core 218A is pushed out of the solenoid coil (ON state). The direction in which the iron core 218A is pushed out is a direction toward the slit 166A. 4 and 5, the energized state (ON state) of the solenoid 218 is indicated by a two-dot chain line, and the non-energized state (OFF state) is indicated by a solid line.

  A support member 219 having a pair of arm portions 219A that rotatably supports the cutting blade 212 described above is attached to the tip of the iron core 218A. Here, the cutting blade 212 has a disk shape, and the peripheral edge (blade edge) 212A has a sharp shape (pointed shape). Further, a shaft portion 212B is formed at the center of the cutting blade 212 so as to protrude on both sides in the central axis direction. The cutting blade 212 is sandwiched from both surfaces by a pair of arm portions 219A, and a shaft portion 212B is inserted into a through hole (not shown) formed in each arm portion 219A. As shown in FIG. 5, a rotating motor 212C is provided on the outer wall surface (upper surface in FIG. 5) of one arm portion 219A, and the rotational force of the rotating motor 212C is cut by a cutting blade via a transmission belt 212D. It is transmitted to the shaft part 212B of 212. Accordingly, the cutting blade 212 is pressed against the continuous paper P while rotating.

  As shown in FIG. 4, the rotational movement motor 215, the solenoid 218, and the rotation motor 212 </ b> C are controlled by the controller 250. The controller 250 is a rotary movement motor based on processing information of the continuous paper P read from a barcode 185 printed on the continuous paper P by a reading sensor 180 (described later) provided upstream of the drum 160 in the transport direction. 215 controls the rotation speed (that is, the movement speed of the support block 216 (the cutting blade 212)) and the rotation amount (that is, the movement amount of the support block 216 (the cutting blade 212)), and turns ON / OFF the solenoid 218; ON / OFF of the rotary motor 212C is controlled. Therefore, when the continuous paper P is cut in full width by the cutting machine 210, the rotary blade 212 is rotated by driving the rotary motor 212C in a state where the solenoid 218 is operated and the cutting blade 212 is pushed out from the slit 166A. Then, the continuous paper P is cut in the width direction W by driving the rotational movement motor 215 of the cutting machine 210 and moving the cutting blade 212 along the guide bar 217 (see FIG. 3).

  Further, the controller 250 detects the mark M provided on the continuous paper P detected by an optical sensor 260 (described later) provided between the drum 160 and the reading sensor 180 (after detecting the mark M, the next time. The time until the mark M is detected) is calculated, and the rotation speed of the drive motor 162 is set so that the conveyance speed of the continuous paper P is equal to the peripheral speed of the outer peripheral surface 160A of the drum 160. Control (voltage control in this embodiment) is performed.

  The crease line forming machine 220, the punching machine 230, and the perforation forming machine 240 are obtained by replacing the cutting blade 212 of the cutting machine 210 with a crease tool 222, a punch hole opening blade 232, and a perforation blade 242, respectively. . For this reason, description of structures other than the folding tool 222, the punch hole opening blade 232, and the perforation blade 242 is omitted.

  The crease tool 222 has the same disk shape as the cutting blade 212 (including the shaft portion 212B), and the peripheral edge is rounded. For this reason, when the crease tool 222 is pressed against the continuous paper P and moved in the width direction of the continuous paper P, streaks along the peripheral edge of the crease tool 222 are formed on the continuous paper P. These lines (grooves) serve as marks when the continuous paper P is folded, and also serve as a guide during folding.

  The punch hole blade 232 has the same disk shape as that of the cutting blade 212 (including the shaft portion 212B), and a plurality of cylindrical protrusions are formed on the peripheral portion with a gap in the circumferential direction. The tip of the cylindrical protrusion has a sharp cutting edge, and by pressing the cutting edge against the continuous paper P, a hole having the same shape as the cross-sectional shape of the cylindrical protrusion is formed in the continuous paper P. For this reason, when the punched blade 232 is pressed against the continuous paper P and moved in the width direction of the continuous paper P, a plurality of holes are formed in the continuous paper P along the width direction.

  The perforation blade 242 has the same disk shape as that of the cutting blade 212 (including the shaft portion 212B), and a plurality of needle-like protrusions are formed on the peripheral portion at intervals in the circumferential direction. By pressing the needle-like protrusions on the continuous paper P, holes having the same shape as the cross-sectional shape of the needle-like protrusions are formed on the continuous paper P. For this reason, when the perforation blade 242 is pressed against the continuous paper P and moved in the width direction of the continuous paper P, a plurality of holes are formed in the continuous paper P along the width direction.

  Note that the crease line forming machine 220, the punching machine 230, and the perforation forming machine 240 are all controlled by the controller 250 as in the cutting machine 210, as shown in FIG. The controller 250 selects a processing machine having a processing tool to be used based on processing information of the continuous paper P (information read by the reading sensor 180).

  As shown in FIG. 2, on the upstream side of the conveyance direction from the drum 160, barcodes 185 printed on both ends in the width direction W of the continuous paper P (barcodes on which processing information on the continuous paper P is recorded). The reading sensor 180 is provided for reading the details of which will be described later. The reading sensor 180 is connected to the controller 250 and sequentially transmits processing information read from the barcode 185 to the controller 250.

  An optical sensor 260 is disposed between the drum 160 and the reading sensor 180. This optical sensor 260 detects marks M (for example, holes, printing, etc.) provided at regular intervals in the transport direction at both ends in the width direction W of the continuous paper P in the same manner as the barcode 185 described above. Sequentially transmitted to 250 (see FIG. 8).

  A platen belt device 310 as a support member is provided outside the drum 160. The platen belt device 310 includes a rotating roller 312, a driven roller 314, and a platen belt 316 that is wound around the rotating roller 312 and the driven roller 314 and wider than the continuous paper P. The rotation roller 312 is connected to a belt motor 318 and receives a driving force (rotational force) from the belt motor 318 to rotate the platen belt 316. The rotation direction of the platen belt 316 is the conveyance direction of the continuous paper P. The rotation speed of the belt motor 318 is controlled by the controller 250 so that the conveyance speed of the continuous paper P is equal to the peripheral speed of the platen belt 316.

  At the rear of the platen belt device 310, a moving device 320 that rotatably supports the rotating roller 312 and the driven roller 314 is provided. The moving device 320 is configured to move the platen belt device 310 in the direction in which the platen belt device 310 approaches the drum 160 (Z direction) and in the direction in which the platen belt device 310 moves away (Z ′ direction). The mechanism for moving the platen belt device 310 includes a solenoid (not shown) as a drive source for moving the platen belt device 310 and a slide for guiding the platen belt device 310 pushed by the solenoid from the Z direction to the Z ′ direction. It is comprised by the rail (illustration omitted). As shown in FIG. 2, when the platen belt device 310 is moved in the Z direction by the moving device 320, the surface 316 </ b> A of the platen belt 316 is pressed against the outer peripheral surface 160 </ b> A of the drum 160. At this time, the continuous paper P is sandwiched between the outer peripheral surface 160A and the platen belt 316. Here, as described above, since the controller 250 controls the peripheral speed of the platen belt 316 to be equal to the transport speed of the continuous paper P, the transport of the continuous paper P is not hindered. The platen belt 316 has a back surface (a surface that does not come into contact with the outer peripheral surface 160A) of the continuous paper P when the cutting blade 212, the crease tool 222, the punch hole opening blade 232, and the perforation blade 242 are pressed against the continuous paper P. ) With an appropriate force (because the platen belt 316 is bent, it becomes an appropriate force). As a result, the continuous paper P can be processed effectively. That is, the continuous paper P can be cut reliably, a hole can be made reliably, and a crease line can be formed reliably (that is, processing accuracy is improved).

  When the platen belt device 310 is not used, the moving device 320 moves the platen belt device 310 in the Z ′ direction. The timing for separating the platen belt device 310 is determined by the controller 250.

  As shown in FIGS. 2 and 3, a disc-shaped slitter 360 (cut forming member) having a blade edge 360 </ b> A directed in the transport direction E will be described later on the downstream side in the transport direction E from the platen belt device 310. The moving device 362 is rotatably supported. When the slitter 360 is used, the blade edge 360 </ b> A contacts the outer peripheral surface 160 </ b> A of the drum 160 and rotates in a direction opposite to the rotation direction of the drum 160. Thus, the continuous paper P wound around the outer peripheral surface 160A is cut along the transport direction E by the slitter 360. Further, a moving device 362 is provided behind the slitter 360. The moving device 362 can be moved in a direction in which the slitter 360 approaches the drum 160 (Y direction) and a direction in which the slitter 360 moves away (Y ′ direction). The mechanism for moving the slitter 360 from the Y direction to the Y ′ direction guides a solenoid (not shown) as a drive source for moving the slitter 360 and the slitter 360 pushed out by the solenoid from the Y direction to the Y ′ direction. A slide rail (not shown) is used. Further, the moving device 362 can move the slitter 360 in a direction orthogonal to the transport direction E. The mechanism for moving the slitter 360 in a direction orthogonal to the transport direction E is a belt (not shown) to which the moving device 362 is fixed, a pair of pulleys (not shown) around which the belt is wound, and one pulley. And a guide rail (not shown) for guiding the moving device 362 in a direction orthogonal to the transport direction E. The timing at which the slitter 360 is separated is determined by the controller 250.

  As shown in FIG. 2, a peeling guide 370 having a substantially triangular cross-sectional shape for peeling the paper P ′ wound around the outer peripheral surface 160A of the drum 160 is provided downstream of the slitter 360 in the transport direction. ing. The leading end 370A of the peeling guide 370 is in contact with the outer peripheral surface 160A of the drum 160, and the end portion (front end portion in the transport direction) of the paper P ′, in which the continuous paper P is cut in the width direction by the cutting blade 212, is drummed. The outer peripheral surface 160A of 160 is peeled off. In addition, an inclined surface 370 </ b> B extending obliquely from the tip 370 </ b> A of the peeling guide 370 is a guide surface that guides the peeled paper P ′ to the nipping and conveying roller 32.

  The sheet P ′ separated by the separation guide 370 is nipped and conveyed by the nipping and conveying roller 32 and guided to the sheet guiding device 24. Further, a stopper 372 is provided on the upstream side of the peeling guide 370 in the transport direction to prevent the paper P ′ from coming off the transport path when the paper P ′ is peeled off by the peeling guide 370. . As a result, the sheet P ′ peeled off from the outer peripheral surface 160 </ b> A is conveyed to the nipping / conveying roller 32 without being removed from the conveying path.

  Further, the sheet processing apparatus 150 is provided with a vacuum device 390 that reduces the internal pressure of the drum 160 to a lower pressure than the outside (in this embodiment, a negative pressure rather than an atmospheric pressure). The vacuum device 390 sucks the air inside the drum 160 through a suction passage 392 that passes through the inside of the rotating shaft 164 to make it a negative pressure. A plurality of fine holes (not shown) are formed in the outer peripheral surface 160A of the drum 160. For this reason, when the inside of the drum 160 is set to a negative pressure by the vacuum device 390, an air flow from the outside to the inside is generated through a minute hole formed in the outer peripheral surface. That is, the drum 160 sucks outside air into the inside through a fine hole. Accordingly, when the continuous paper P is wound around the outer peripheral surface 160A of the drum 160 having a negative pressure inside, the continuous paper P is attracted to the outer peripheral surface 160A. Thereby, when the continuous paper P is wound around the outer peripheral surface 160 </ b> A of the drum 160, the continuous paper P is restrained from being shifted in the width direction. That is, meandering conveyance of the continuous paper P in the width direction is suppressed. Further, in the vacuum device 390, the suction force (differential pressure between the drum 160 and the outside) is controlled by the controller 250. The controller 250 controls to increase the suction force when the continuous paper P is processed, and to reduce the suction force so that the paper P ′ can be peeled by the peeling guide 370 when the continuous paper P is not processed. As a result, the continuous paper P is less likely to be displaced in the width direction W during processing, and the paper P ′ is effectively peeled off by the peeling guide 370.

  Next, an example of the barcode 185 described above will be described. The bar code 185 is a bar code on which a cutting instruction (cutting information) for the continuous paper P is recorded. In the barcode 185 shown in FIG. 8, “0-3-12.5” is recorded from the upstream side to the downstream side in the transport direction E. Here, “0” is A block information, and “3” is B block information. “12.5” is C block information.

  The bar code 185 indicates that (A-0) is cutting control information in the transport direction E of the continuous paper P, and (B-3) is information for cutting the continuous paper P along the width direction W. (C) is information indicating a range of 12.5 inches from the designated end. These are information indicating the cutting positions in the conveyance direction E and the width direction W of the continuous paper P.

  In this example, no symbol is added after 12.5. However, when alphabets such as A, B, and C are added, this is D block information, and the paper transport destination ( Paper stacks 26, 28, etc.). Further, (D-C) means purging, so-called discarding processing, and unnecessary portions that appear when cutting out continuous paper or cutting are guided to a waste paper storage box (not shown).

  Further, the barcode 185 shown in FIG. 8 records processing information for cutting the continuous paper P, but the present invention is not limited to this configuration, and the barcode forms a crease line on the continuous paper P. Processing information for punching holes and forming perforations may be recorded.

  Next, the operation of the sheet processing apparatus 150 will be described. As shown in FIG. 1, the continuous paper P supplied from the continuous paper supply device 14 is conveyed to the paper buffer mechanism 16 and is conveyed to the paper processing device 150 while adjusting the tension applied to the continuous paper P. In the paper processing apparatus 150, first, processing information is read from the barcode 185 printed on both ends of the continuous paper P in the width direction W by the reading sensor 180, and the processing information is transmitted to the controller 250. In addition, the marks M provided at both ends of the continuous paper P in the width direction W are detected by the optical sensor 260 and transmitted to the controller 250. Then, the drum 160 rotates and the leading end side of the continuous paper P is wound around the outer peripheral surface 160 </ b> A of the drum 160. At this time, the vacuum device 390 operates. For this reason, the continuous paper P is adsorbed to the outer peripheral surface 160A because the inside of the drum 160 has a negative pressure from the outside. Hereinafter, a case where the continuous paper P is cut along the virtual lines A to E as illustrated in FIG. 9 will be described.

  First, the controller 250 uses the moving device 362 to adjust the position in the width direction W so that the blade edge 360A of the slitter 360 overlaps the virtual line A in order to cut the continuous paper P along the virtual line A shown in FIG. To do. Next, the cutting edge of the slitter 360 is pressed against the continuous paper P and rotated in the direction opposite to the transport direction. By performing this pressing state up to the position of the imaginary line E, cutting along the imaginary line A is performed.

  Next, in order to cut the continuous paper P along the virtual line B shown in FIG. 9, the controller 250 increases the rotation speed of the drum 160 so that the peripheral edge 212 </ b> A of the cutting blade 212 of the cutting machine 210 overlaps the virtual line B. adjust. Then, after the peripheral portion 212A and the virtual line B overlap, the rotational speed of the drum 160 is adjusted so that the peripheral speed of the outer peripheral surface 160A of the drum 160 is equal to the transport speed of the continuous paper P. Next, as shown in FIG. 6, the cutting blade 212 is pushed out from the slit 166 and rotated to rotate along the imaginary line B from the width direction end portion (the lower end portion 40 in FIG. 6) of the continuous paper P. In the embodiment, it is moved along the width direction W). The continuous paper P is cut along the virtual line B by moving the cutting blade 212 along the virtual line B to a position overlapping the virtual line A. At this time, the controller 250 increases the suction force by the vacuum device 390 simultaneously with the function of the cutting blade 212, moves the platen belt device 310 in the Z direction, and sandwiches the continuous paper P between the outer peripheral surface 160A and the platen belt 316. The peripheral speed of the surface 310A of the platen belt 316 is controlled to be the transport speed of the continuous paper P. As a result, the continuous paper P is accurately cut along the imaginary line B without stopping the conveyance of the continuous paper P and without shifting the continuous paper P to form the paper P′1.

  Next, in order to cut the continuous paper P along the virtual line C shown in FIG. 9, the controller 250 increases the rotation speed of the drum 160 so that the peripheral edge 212 </ b> A of the cutting blade 212 of the cutting machine 210 overlaps the virtual line C. adjust. At this time, the controller 250 sets the suction force by the vacuum device 390 to be low, and moves the platen belt device 310 in the Z ′ direction to separate the platen belt 316 from the outer peripheral surface 160 </ b> A of the drum 160. After the peripheral portion 212A and the imaginary line C overlap, the rotational speed of the drum 160 is adjusted so that the peripheral speed of the outer peripheral surface 160A of the drum 160 is equal to the transport speed of the continuous paper P. Next, as shown in FIGS. 6 and 7, the cutting blade 212 is pushed out from the outer peripheral surface 160 </ b> A through the slit 166 and rotated, and is rotated from the end in the width direction of the continuous paper P (upper end 42 in FIG. 6). It is moved along the line C (in the present embodiment, along the width direction W). The continuous paper P is cut along the virtual line C by moving the cutting blade 212 along the virtual line C to a position overlapping the virtual line A. At this time, the controller 250 increases the suction force by the vacuum device 390 at the same time as the cutting blade 212 functions, and moves the platen belt device 310 in the Z direction to sandwich the continuous paper P between the outer peripheral surface 160A and the platen belt 316 and The peripheral speed of the belt 316 is controlled so as to be the conveyance speed of the continuous paper P. Thereby, the continuous paper P is accurately cut along the virtual line C without stopping the conveyance of the continuous paper P, without stopping the conveyance of the continuous paper P, and without shifting the continuous paper P. '2 is formed.

  Similarly, the controller 250 controls the cutting machine 210, the rotation of the drum 160, the platen belt device 310, and the vacuum device 390 in order to cut the continuous paper P along the virtual line D. As a result, the continuous paper P is accurately cut along the virtual line D without being displaced, and the paper P′3 is formed.

  The controller 250 then rotates the cutting machine 210, the drum 160, and the platen belt device 310 so as to cut the continuous paper P along the virtual line E (cut from the width direction end 40 to the width direction end 42 of the continuous paper P). And the vacuum device 390 is controlled. Thereby, the continuous paper P is accurately cut along the virtual line E without stopping the conveyance of the continuous paper P, and the paper P′4 (upper paper in the drawing) and the paper P′5 are cut. (The lower sheet in the figure) is formed. Further, when the blade edge 360 </ b> A of the slitter 360 reaches the imaginary line E, the slitter 360 is separated from the drum 160. That is, the slitter 360 is moved in the Z ′ direction by the moving device 320 controlled by the controller 250.

  After cutting the imaginary line E, the controller 250 sets the suction force by the vacuum device 390 to be low, and moves the platen belt device 310 in the Z ′ direction to separate the platen belt 316 from the outer peripheral surface 160A of the drum 160. Then, until the next processing information is transmitted from the reading sensor 180, the peripheral speed of the drum 160 is controlled to be equal to the conveying speed of the continuous paper P.

  The width direction end portion of the continuous paper P on which the bar code 185 and the mark for detecting the conveyance speed are formed is cut along the conveyance direction by a slitter (not shown) fixed in the paper processing apparatus 150. Then, it is conveyed to a waste paper storage box as an unnecessary part. Here, the width direction end portions 40 and 42 of the continuous paper P shown in FIG. 9 are imaginary lines showing portions cut by a fixed slitter.

  In the first embodiment, the continuous paper P is cut along the imaginary lines A to E shown in FIG. 9. For example, a crease line may be formed along the imaginary line A. A plurality of punch holes may be formed along the perforations, and perforations may be formed along the imaginary line C.

  In the first embodiment, the continuous paper P is configured to be processed into a shape as shown in FIG. 9. However, when the continuous paper P is processed into a shape as shown in FIG. 10, a slitter 360 is used. It suffices to provide a plurality. When processing the continuous paper P into a shape as shown in FIG. 10, the virtual line A, the virtual line B, the virtual line C, the virtual line D, the virtual line E, the virtual line F, and the virtual line G are cut in this order. As a result, sheets P′1, P′2, P′3, P′4, P′5, and P′6 are formed.

  In the above-described embodiment, the printed continuous paper P is processed by the paper processing device 150. However, the present invention is not limited to this configuration, and an image can be formed between the paper buffer mechanism 16 and the paper processing device 150. A simple printing device may be provided, and the continuous paper P may be processed by the paper processing device 150 while printing by the printing device.

  Further, in the above-described embodiment, the continuous paper P is cut in the width direction by rotating the disk-shaped cutting blade 212 and moving it in the width direction of the continuous paper P. However, the present invention is limited to this configuration. The shape of the cutting blade may be any shape as long as the continuous paper P can be cut in a direction intersecting the transport direction E. For example, a plurality of plate-shaped cutting blades may be continuous with the continuous paper P. Alternatively, the continuous paper P may be cut. Of course, the same applies to the folding tool 222, the punch hole blade 232, and the perforation blade 242, and any shape can be used as long as the desired processing can be applied to the continuous paper P in the direction intersecting the transport direction E. Alternatively, the continuous paper P may be processed by continuously driving a plurality of plate-like crease tools (or rod-shaped punch hole blades or plate-like perforation blades) onto the continuous paper P.

  Furthermore, in the above-described embodiment, the vacuum device 390 has a configuration in which the inside of the drum 160 is set to a negative pressure from the outside to adsorb the continuous paper P to the outer peripheral surface 160A. However, the present invention is not necessarily limited to this configuration. Alternatively, the polarity of the outer peripheral surface 160A of the drum 160 and the polarity of the continuous paper P may be reversed so that the continuous paper P is electrostatically attracted to the outer peripheral surface 160A. In this case, it is necessary to provide a drum charging device that sets the polarity of the outer peripheral surface of the drum 160 and a paper charging device that sets the polarity of the continuous paper P in the paper processing device.

  In the above-described embodiment, the cutting machine 210, the crease line forming machine 220, the punching machine 230, and the perforation forming machine 240 are accommodated in the drum 160. However, the present invention is limited to this configuration. It is not necessary to have a configuration in which at least one of these processing machines is accommodated.

  In the above-described embodiment, the rotational movement motor 215, the trapezoidal screw 213, and the bearing 214 are used to move the cutting blade 212, the crease tool 222, the punch hole opening blade 232, and the perforation blade 242 in the direction intersecting the transport direction E. The slide mechanism including the support block 216 and the guide bar 217 is used. However, the present invention is not limited to this configuration, and the cutting blade 212, the crease tool 222, the punch hole opening blade 232, and the perforation blade 242 are used. Any mechanism may be used as long as it can be moved in a direction crossing the transport direction E. As an example of the mechanism, as shown in FIG. 11 (showing the cutting machine 210), a belt 404 is wound around a pair of pulleys 402, and a support block 406 (corresponding to the support block 216) is fixed on the belt 404. The guide bar 408 (corresponding to the guide bar 217) guides the movement direction of the support block 406, and the driving force from the rotational movement motor 410 (corresponding to the rotational movement motor 215) connected to one of the pair of pulleys 402 A configuration in which the cutting blade 212 (fold tool 222, punch hole opening blade 232, or perforation blade 242) supported by the support block 406 is moved in a direction intersecting the conveying direction E by rotating the belt 404 with (rotational force). It is good.

  In the above-described embodiment, the rotational speed of the drum 160 is controlled so that the peripheral speed of the drum 160 rotated by the controller 250 and the conveyance speed of the continuous paper P are equal to each other. It is not necessary to be limited to this configuration, and as shown in FIG. 12, a cutting machine 210, a crease line forming machine 220, and a punching machine 230 are placed in a box-shaped moving body 422 that moves on the conveyance path of the continuous paper P. The perforating machine 240 is accommodated, and the moving speed of the moving body 422 in the transport direction is set to a speed equivalent to the transport speed of the continuous paper P to be transported. It is good also as a structure to give. In the paper processing apparatus 420 shown in FIG. 12, the paper processing apparatus 420 is provided with a trapezoidal screw 424 extending along the conveyance direction E of the continuous paper P, and the moving body 422 is formed on the male screw of the trapezoidal screw 424. The formed female screw is screwed. The trapezoidal screw 424 has one end connected to a motor 426 fixed to the inner wall of the paper processing apparatus 420 and the other end rotatably supported by a bearing 428 fixed to the inner wall of the paper processing apparatus 420. . Furthermore, a guide rail 430 is provided below the trapezoidal screw 422 in parallel to the trapezoidal screw 422, and the moving body 422 is slidably supported by the guide rail 430. Accordingly, when the motor 426 rotates and the trapezoidal screw 424 rotates, the moving body 422 moves in the transport direction E along the guide rail 430. The platen belt device 310 is also moved in the transport direction E together with the moving body 422 by the moving device 320.
