Description

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

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

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

  In these processes for continuous paper, it is required to cut the paper to a required size without delay while transporting the paper at high speed and transport it to a required processing unit.

  For this reason, the cutting along the paper transport direction is generally performed by a slitter having a tooth surface protruding on the paper transport surface. On the other hand, cutting in the direction orthogonal to the paper transport direction (paper width direction) can be easily accommodated to any size while the paper is stopped as used in a relatively low speed paper cutting mechanism such as CAD or facsimile. Instead of a movable cutter type that can be used, a rotary cutter is often used that has cutter teeth at a predetermined full width of the paper and can rotate the full width of the paper at the same time by rotating the cutter teeth arranged in a shaft shape ( For example, Patent Document 1).

  However, since the entire cutting width of the rotary cutter shaft is cut by the above cutting mechanism, a cutting operation that changes the width in the direction orthogonal to the conveyance of the paper to be cut cannot be performed. Even if the slitter cuts along the paper transport direction, the entire width is cut at once by the rotary cutter. After the processing, it is necessary to largely separate the respective paper transport positions and transport one paper to another paper cutting means via a different paper transport path for processing.

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

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

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

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

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

In addition, the paper cutter by moving the cutter teeth used in the above-mentioned CAD plotter can cut the paper vertically and horizontally at any size and position, but it is necessary to stop the paper at the time of cutting, Not only can the continuous paper not be cut accurately in the width direction of the continuous paper while the continuous paper is being conveyed at high speed, but also the performance of the paper processing system itself is greatly reduced as the continuous paper stops ( For example, Patent Documents 2 and 3).

  FIG. 1 is an overall configuration diagram of a sheet processing system 12 to which a sheet processing apparatus 150 according to the present embodiment is applied. The paper processing device 150 is a device that forms part of the paper processing system 12 and cuts the conveyed continuous paper P into a predetermined size.

  On the upstream side of the paper processing system 12 in the conveying direction of the continuous paper P (hereinafter, sometimes simply referred to as “upstream side”), the continuous paper supply device 14 that sequentially unwinds the continuous paper P wound in advance in a roll shape. Is provided.

  A paper buffer mechanism 16 is provided on the downstream side of the continuous paper supply device 14 in the conveyance direction of the continuous paper P (hereinafter, also simply referred to as “downstream side”), and is alternately provided in the vertical direction. The continuous paper P is conveyed in a state where the continuous paper P is wound around the roller 18.

  The roller 18 positioned below the paper buffer mechanism 16 is movable up and down, and thereby, the tension applied to the continuous paper P is adjusted, and the continuous paper P is pulled or cut, or the continuous paper P is removed. Prevents problems such as loosening and bending.

  A paper processing apparatus 150 according to the present embodiment is disposed on the downstream side of the paper buffer mechanism 16 and cuts the continuous paper P into a predetermined size. In addition, although arrange | positioned here at the upper part of the continuous paper P conveyed, you may arrange | position at the lower part of the continuous paper P conveyed. Although not shown, a printing device capable of forming an image is disposed between the paper buffer mechanism 16 and the paper processing device 150, and the continuous paper P on which image formation has been performed is reduced to a predetermined size by the paper processing device 150. You may make it cut | disconnect.

<Paper handling device>
Here, the sheet processing apparatus 150 will be described.

  As shown in FIG. 1, the sheet processing apparatus 150 is provided with a slitter unit (first cutting unit) 152 that cuts the continuous paper P along the conveyance direction of the continuous paper P on the upstream side. A cutter unit (second cutting unit) 153 that cuts the continuous paper P along a direction orthogonal to the conveying direction of the continuous paper P (width direction of the continuous paper P) is disposed on the downstream side of the slitter unit 152. ing.

(Slitter part)
As shown in FIG. 2, the slitter unit 152 is disposed obliquely with respect to the width direction of the continuous paper P supported and conveyed by a frame (not shown) constituting the paper processing apparatus 150 (arrangement angle: θ). The substantially rectangular parallelepiped holding member 154 is provided.

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

  The laser cutters 156, 158, and 160 are slidable by driving means such as linear motors 161, 162, and 163 connected to the control unit 155 shown in FIG. 3, and slide along the longitudinal direction of the holding member 154. By moving, it is skewed along the width direction of the continuous paper P being conveyed.

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

  Both ends of the continuous paper P in the width direction are cut off by the laser cutters 156 and 160, but the cut-off area is stored in the waste paper storage box 58 (see FIG. 1) as an unnecessary portion 56. Further, the continuous paper P is divided into continuous papers A and B (two in this case) in the width direction by the laser cutter 158 and conveyed to the cutter unit 153 side.

  Here, the unnecessary portion 56 is accommodated in the waste paper storage box 58 on the upstream side of the cutter portion 153, but the unnecessary portion 56 is accommodated in the waste paper storage box 58 on the downstream side of the cutter portion 153. You may make it do. Although the unnecessary part 56 accommodated on the upstream side of the cutter part 153 is continuous, the unnecessary part 56 accommodated on the downstream side of the cutter part 153 has a chip shape.

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

(Cutter part)
As shown in FIG. 2, the cutter unit 153 has a substantially rectangular parallelepiped holding member 164 disposed obliquely (arrangement angle: θ) with respect to the width direction of the continuous paper P to be conveyed, like the slitter unit 152. Is provided. The holding member 164 is provided with a laser cutter 166 and can be slid by a driving means such as a linear motor 168 connected to the control unit 155 (see FIG. 3).

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

  Here, bar codes 132 (see FIG. 4), which will be described later, are recorded at both ends in the width direction of the conveyed continuous paper P. As shown in FIG. 1, the continuous paper P of the paper processing apparatus 150 is recorded. On the upstream side in the transport direction, read sensors 134 and 136 such as a line sensor for reading the cutting position information by the bar code 132 (the read sensor 134 on the front side of the drawing in FIG. 1 and the reading sensor 136 on the back side of the drawing) are arranged. It is installed.

  Information read by the reading sensors 134 and 136 is input to the control unit 155. Then, the linear motor 168 is driven by the control unit 155 based on the cutting position information by the barcode 132, and the laser cutter 166 moves.

Specifically, after the linear motor 168 reads the information by the barcode 132 of the continuous paper P conveyed by the reading sensors 134 and 136, the control unit 155 controls the linear motor 168 of the continuous paper P conveyed in FIG. From the conveyance speed (V _P ), the arrangement angle (θ) of the holding member 154, and the cutting range of the laser cutter 166 (H: (0 ≦ H ≦ full width dimension of continuous paper P)), the moving speed (V _C of the laser cutter 166). ) And the laser cutter 166 is moved. Here, the holding member 154 can change the arrangement angle, and the arrangement angle can be changed according to the conveyance speed of the continuous paper P.

  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, the continuous paper P is cut into a desired paper size by the slitter unit 152 and the cutter unit 153 according to the size of the continuous paper P to be conveyed.

  By the way, as described above, the continuous paper P conveyed by an instruction from the control unit 155 is cut into a desired paper size by the slitter unit 152 and the cutter unit 153 and guided to a predetermined conveyance path. As shown in FIG. 4, barcodes (cutting instruction information) 132 indicating the cutting position of the continuous paper P are recorded in advance at both ends in the width direction of the continuous paper P being conveyed. Since the barcode 132 is recorded in an area corresponding to the unnecessary portion 56 shown in FIG. 4, the barcode 132 does not remain on the cut paper.

  Here, the barcode 132 will be described.

  As shown in FIG. 4, the barcode 132 is recorded as “0-3-12.5” from the upstream side to the downstream side in the conveyance direction of the continuous paper P. Here, “0” is A block information, and “3” is B block information. “12.5” is C block information.

  That is, here, the cutting control information in the conveyance direction of the continuous paper P is (A-0), and the range from the designated end to 12.5 inches (C) is cut along the width direction of the continuous paper P. (B-3: cutting range by the cutter unit 153), which is information indicating the cutting position of the continuous paper P in the transport direction and the width direction.

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

  Based on the cutting position information by the bar code 132, the laser cutter 166 moves. Here, FIGS. 5 and 6 show the operations of the laser cutters 156, 158, 158 and 166. A solid line indicates a state in which laser light is emitted, and a wavy line indicates a state in which laser light is not emitted.

  As shown in FIGS. 2 and 5, when cutting sheets a, b, c, d having different sizes and unnecessary portions e, the laser cutters 156, 158, 160 are the same as shown in FIGS. Laser light is emitted at the position (solid line), and the continuous paper P being conveyed is cut (cut lines A, B, and C).

  On the other hand, the laser cutter 166 emits laser light while moving from point D to point E, and cuts the cut continuous paper along the width direction. The laser cutter 166 does not emit laser light from point E to point F. When reaching the point F, the laser cutter 166 emits laser light while moving until reaching point G. As a result, the sheet a is cut.

  Next, the laser cutter 166 does not emit laser light from point G to point H, and when it reaches point H, it emits laser light while moving until it reaches point I. Thereby, the unnecessary part d, the paper b, the paper c, and the unnecessary part e are cut.

  Thus, the sheets a, b, and c cut to a predetermined size by the laser cutters 156, 158, and 160 of the slitter unit 152 and the laser cutter 166 of the cutter unit 153 are disposed on the downstream side of the sheet processing apparatus 150. The sheet guide device 24 is guided to the sheet stacks 26, 28 and the like. Unnecessary portions d and e are guided to a waste paper storage box 58 (see FIG. 1).

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

  For example, as shown in FIG. 7, a holding member 170 arranged in parallel with the holding member 164 is provided between the holding member 154 and the holding member 164, and a plurality of laser cutters 172 and 174 are provided on the holding member 170. The movement axes are different from each other.

  With the laser cutters 156, 158, 160, 172, 174, 166, as shown in FIG. 7 and FIG. 8A, sheets a, b, c, d, e, f, g, h, i of different sizes are used. , J, k and unnecessary portions l, m are cut.

  FIG. 8B shows the operation of each laser cutter 156, 158, 160, 172, 174, 166. Similarly to the above, the laser cutters 156, 158, and 160 emit laser light at the same position (solid line), and cut the continuous paper P that is conveyed (cut lines A, B, and C).

  The two-dot chain line indicates the locus of the laser cutter 166 on the continuous paper P, the one-dot chain line with a small interval is the locus of the laser cutter 172 on the continuous paper P, and the one-dot chain line with a larger interval than the laser cutter 172 is continuous. The locus of the laser cutter 174 on the paper P is shown. Each dark line indicates a state in which laser light is emitted, and a thin line indicates a state in which laser light is not emitted.

  9A is an explanatory diagram for explaining the operation of the laser cutter 166, and dotted lines A, B, and C indicate cutting lines by the laser cutters 156, 158, and 160, respectively (FIG. 9 ( The same applies to B) and (C)), and the solid line is a cutting line by the laser cutter 166. According to this, it can be seen that the sheets a and b are cut by the laser cutters 156, 158 and 166.

  Next, FIG. 9B shows an explanatory diagram for explaining the operation of the laser cutter 172. The solid line is a cutting line by the laser cutter 172, and the laser cutter 166 shown in FIG. A part of the cutting line is indicated by a one-dot chain line. According to this, it is understood that the sheets g and h are cut by the laser cutters 156, 158, 166, and 172.

  FIG. 9C is an explanatory diagram for explaining the operation of the laser cutter 174. The solid line is a cutting line by the laser cutter 174, and the laser cutter 166 shown in FIG. 9A is cut. A part of the line is indicated by a one-dot chain line. According to this, it is understood that the papers c, d, e, f, i, j, k and unnecessary portions l, m are cut by the laser cutters 156, 158, 160, 166, 174.

  In this way, by making it possible to cut the width direction of the continuous paper P conveyed using the laser cutter 166 or the like, for example, there is a difference in the amount of information required for each customer, or different form forms are processed together. For example, continuous paper A can be used for different sizes of paper, such as by reducing the total performance due to paper setup between jobs without changing the post-processing machine, and by changing or setting up continuous paper A and B. , B can be continuously cut to a desired paper size in a variable manner while preventing wasteful consumption of B.

  Further, the cutting line cut along the conveyance direction of the continuous paper P and the cutting line cut along the width direction of the continuous paper P are orthogonal to each other, and the orthogonal portion is set as a cutting start position or a cutting end position. (So-called horizontal T-shaped control (region Q shown in FIG. 9), L-shaped control, + -shaped control, crank-type control).

  In this embodiment, as shown in FIGS. 9B and 9C, the movements of the laser cutters 172 and 174 are stopped during the conveyance of the continuous paper P, and the conveyed continuous paper P is cut along the conveyance direction. However, the laser cutters 156, 158, and 160 may be skewed while the continuous paper P is being transported, and cut along the width direction of the continuous paper P being transported.

  Further, here, as shown in FIG. 8B, the continuous paper P conveyed using the laser cutters 166, 172, and 174 can be cut in the width direction, but these laser cutters 166, 172, An auxiliary cutter 167 may be provided separately for the purpose of assisting 174. When the movement of the laser cutters 166, 172, 174 is not in time for the conveyance speed of the continuous paper P, the auxiliary cutter 167 can be used for cutting. The auxiliary cutter 167 stands by so that the holding member that holds the auxiliary cutter can move from the upstream side to the downstream side of the conveyed continuous paper P.

  Furthermore, although the laser cutters 166, 172, and 174 are used here, the present invention is not limited to this as long as continuous paper conveyed at high speed can be cut. For example, the continuous paper may be cut by applying a liquid such as water to the continuous paper conveyed by being jetted at a high pressure. Alternatively, the continuous paper may be cut by fine vibration by applying ultrasonic waves to a cutter tooth having a substantially conical cutting edge (which may be shaped like a needle).

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