  By the way, the paper processed by the above-described processing apparatus or the like is usually subjected to some printing before processing. In many cases, a sheet printed by a printer using an electrophotographic method using a charged image has a size smaller than that before printing due to heating and cooling in the printing process. In addition, some printing presses are equipped with a humidifier to cope with the heating operation, and the printed paper may have an enlarged size. Further, the printed paper may be enlarged depending on the ambient environment of the printing machine, for example, the humidity. Therefore, if such a reduced or enlarged sheet is processed at the same processing position as that of a sheet having a predetermined size, there is a possibility that the processing cannot be performed at an appropriate position.

  Therefore, in the paper processing apparatus disclosed in Patent Document 1, the actual size of the reduced or enlarged paper is measured, and input for correcting the processing position in the processing information may be performed. However, there was a problem that it took time and effort.

  In the cutting apparatus of Patent Document 2, since the cutting position is determined based on the actual length of the paper, even a reduced or enlarged paper is cut at an appropriate position. However, cutting at an appropriate position is limited only to the position in the conveyance direction, and the position in the other direction is not guaranteed.

  In the cutting system of Patent Document 3, an actual measurement size is obtained by photographing a registration mark with a line sensor camera, so even a reduced or enlarged sheet is cut at an accurate position. However, since the registration mark needs to be printed accurately, if the printing accuracy of the paper is not good, there is a possibility that cutting at an accurate position cannot be performed. Further, since it is necessary to shoot with a camera, there is a problem that the apparatus is complicated and expensive.

  Next, the operation of the sheet processing apparatus 1 will be described in the following (1) to (5).

(1) First, processing information which is a series of processing contents for a sheet is set. This setting is performed, for example, by a user inputting from an operation panel (not shown). As a result, the processing content is set, and the processing position setting means 860 is activated to set the processing position based on the default size of the paper, for example, 297 mm × 211 mm for A4 size paper. The

  The processing information may be registered and set at the manufacturing stage of the apparatus. According to this, the labor of inputting can be omitted.

(2) Next, processing information to be executed is designated.
4-6 has shown an example of the machining information to implement. As shown in FIG. 4, a position mark (register mark) 102 and a barcode 103 are printed on the paper 100 to be processed together with the main printing unit 101. In this case, since the processing information is automatically specified by the barcode 103, it is not necessary to specify it here. When the barcode 103 is not used, the processing information is designated by the operator inputting from the operation panel. As shown in FIG. 5, the processing information is obtained by first cutting the paper 100 along the solid lines A1 and A2 by the first cutting device unit 4A, and then by the second cutting device unit 4B. The cutting process along B1 and B2 is performed, then the cutting process along the solid lines C1 and C2 is performed by the third cutting apparatus unit 4C, and then the solid lines D1, D2, and D3 are performed by the fourth cutting apparatus unit 4D. A sheet having a folding mold 210 as shown in FIG. 6 is then subjected to folding processing along the alternate long and short dash lines E1 and E2 in this order by the folding mold forming unit 5. To get eight 200. Here, the positions of the solid lines A1, B1, C1, C2, B2, and A2 to be subjected to the cutting process, that is, the processing positions are indicated by the distances W1, W2, W3, W4, W5, and W6 from one vertical side of the paper 100. The positions of the solid lines D1, D2, and D3 to be subjected to the cutting process, that is, the processing positions are indicated by the distances L1, L3, and L5 from the front lateral side, and are indicated by the alternate long and short dashed lines E1 to be subjected to the folding mold forming process. The position of E2, that is, the processing position, is indicated by distances L2 and L4 from the front side, the entire width of the paper is indicated by a distance W7, and the total length of the paper is indicated by a distance L6. . These distances are determined on the assumption that the paper 100 has a predetermined size.

(3) However, in reality, the paper 100 may have a size that is reduced or enlarged compared to a predetermined size due to printing. Such a case is shown in FIG. W1 'etc. and L1' etc. in FIG. 7 correspond to W1 etc. and L1 etc. in FIG. 5, but are smaller or larger than them.

  Therefore, the sheet 100 is placed on the sheet placing table 111 of the sheet feeding unit 11, and the actual total length L 6 ′ and total width W 7 ′ of the sheet 100 are measured by the scales 112 and 113. And the measured actual dimension is input by the actual dimension input means 871, for example, the numeric keypad of the operation panel. These are performed by the operator.

(4) When the actual dimension is input, the correction means 880 is activated. That is, first, the following calculation is performed to obtain L1 ′ to L5 ′ and W1 ′ to W6 ′. Then, L1 to L5 and W1 to W6 set by the machining position setting means 860 are replaced with L1 ′ to L5 ′ and W1 ′ to W6 ′. That is, L1 to L5 and W1 to W6 are corrected to L1 ′ to L5 ′ and W1 ′ to W6 ′.
L1 ′ = L1 × (L6 ′ / L6)
L2 ′ = L2 × (L6 ′ / L6)
L3 ′ = L3 × (L6 ′ / L6)
L4 ′ = L4 × (L6 ′ / L6)
L5 ′ = L5 × (L6 ′ / L6)
W1 ′ = W1 × (W7 ′ / W7)
W2 ′ = W2 × (W7 ′ / W7)
W3 ′ = W3 × (W7 ′ / W7)
W4 ′ = W4 × (W7 ′ / W7)
W5 ′ = W5 × (W7 ′ / W7)
W6 ′ = W6 × (W7 ′ / W7)

(5) Then, at the processing positions D1, E1, D2, E2, D3 and the processing positions A1, B1, C1, C2, B2, A2 indicated by the corrected distances L1 ′ to L5 ′ and W1 ′ to W6 ′, Processing is performed as shown in (5-1) to (5-7) below.

(5-1) First, the sheets 100 are sent one by one from the bundle of sheets 100 placed on the sheet feeding unit 11 to the conveyance path 20 and enter the conveyance correction unit 803. If the fed paper 100 is slanted, the conveyance correction unit 803 straightens it. Further, if two or more sheets 100 that have been sent overlap, the conveyance correction unit 803 detects that and stops conveyance of the sheet 100. If the sheet 100 is straight and one sheet, it is transported to the next.

(5-2) The paper 100 conveyed next enters the information reading unit 804 after the leading edge is detected by the paper leading edge sensor 201. The information reading unit 804 reads the position mark 102 and the barcode 103 on the paper 100 by the CCD sensor 805. This read information is sent to the control means 800. The control means 800 stores the read information and controls each subsequent means based on the read information. Note that the paper 100 whose information cannot be read by the information reading unit 804 is determined to be unclear, and is dropped to the lower disposal tray 802 by the next rejection unit 806.

(5-3) The paper 100 that has passed the reject means 806 enters the first cutting device section 4A after the leading edge is detected by the paper leading edge sensor 202. The first cutting device unit 4A is ON-controlled by the processing control means 852 of the control means 800, and at the same time, the positions of the two solid lines A1 and A2, that is, the distances W1 ′ and W6 ′ by the position control means 851 of the control means 800. (FIG. 7) is controlled so that the two cutting cutters are positioned respectively. Therefore, the sheet 100 is cut along the solid lines A1 and A2, that is, in the transport direction by the first cutting device unit 4A. As a result, the sheet 100 is conveyed to the next second cutting device unit 4B in the form of FIG. The unnecessary part X1 is dropped into the trash box 801.

(5-4) The second cutting device section 4B is turned on by the machining control means 852 of the control means 800, and the position of the two solid lines B1, B2 by the position control means 851 of the control means 800, that is, the distance Two cutting cutters are controlled to be positioned at W2 ′ and W5 ′ (FIG. 7), respectively. Accordingly, the sheet 100 in FIG. 8A is cut along the solid lines B1 and B2, that is, in the transport direction by the second cutting device unit 4B. As a result, the sheet 100 is conveyed to the next third cutting device unit 4C in the form shown in FIG. 8B.

(5-5) The third cutting device section 4C is turned on by the processing control means 852 of the control means 800, and the position of the two solid lines C1, C2 by the position control means 851 of the control means 800, that is, the distance Two cutting cutters are controlled to be positioned at W3 ′ and W4 ′ (FIG. 7), respectively. Accordingly, the paper 100 in FIG. 8B is cut along the solid lines C1 and C2, that is, in the transport direction by the third cutting device unit 4C. Thereby, the paper 100 is conveyed to the fourth cutting device unit 4D in the form of FIG. The unnecessary part X2 is dropped into the trash box 801 by the next-stage chip dropping means 807.

  Note that the leading edge of the paper 100 in FIG. 8C is detected by the paper leading edge sensor 203 before entering the fourth cutting device unit 4D.

(5-6) The fourth cutting device section 4D is on-controlled by the processing control means 852 of the control means 800. In the fourth cutting device unit 4D, the paper 100 of FIG. 8C is cut by three solid lines D1, D2, and D3, that is, a distance L1 ′, whenever the cut position is detected by the cut position sensor 204. Stop at L3 ′ and L5 ′ (FIG. 7). Each time the sheet 100 is stopped, the pair of cutting cutters 41 are cut along the solid line D1 or the like, that is, in a direction orthogonal to the transport direction. As a result, the sheet 100 is conveyed to the folding mold forming unit 5 in the form shown in FIG. The unnecessary portion X3 falls to the trash box 801.

(5-7) The folding mold forming unit 5 is on-controlled by the processing control means 852 of the control means 800. In the folding mold forming unit 5, the folding position indicated by two alternate long and short dash lines E1 and E2, that is, distances L2 ′ and L4, is detected each time the folding position sensor 205 detects the folding position of the sheet 100 in FIG. Stop at '(Fig. 7). Whenever the sheet 100 is stopped, the folding mold 201 is formed along the alternate long and short dash line E1 by the pair of folding mold forming pressing dies 51, that is, in the direction orthogonal to the transport direction. As a result, the paper 100 is sent to the paper discharge means 12 in the form shown in FIG.

  As described above, in the paper processing apparatus 1 of the present embodiment, the processing position set based on the default value is corrected based on the actual dimensions of the paper to be processed, here, the paper reduced or enlarged by printing. Then, processing is performed based on the corrected processing position. Therefore, according to the paper processing apparatus 1 of the present embodiment, it is possible to perform processing at an appropriate position even on paper that is reduced or enlarged by printing.

  Moreover, the operation for obtaining the above-described effects can be easily performed because the actual dimensions are simply measured by the scales 112 and 113 and the measured values are input by the actual dimension input means 871.

  Further, since the above-described operation and effect can be realized by the scales 112 and 113 for measuring the actual dimension, the actual dimension input means 871 that can be realized by the operation panel, the correction means 880 that performs simple calculation, and the like, the configuration is simple. It can be realized at low cost.

  In the sheet processing apparatus 1, a sheet feeding unit 11 shown in FIG. 9 may be used. The paper feeding means 11 has a known paper size detecting means 114. The paper size detection unit 114 includes a rear guide plate 115 and a side guide plate 116 (paper guide) provided on the paper placement table 111, and a rear guide is provided at the rear edge of the paper 100 placed on the paper placement table 111. By sliding the plate 115 and the side guide plate 116 against the side edges, the length and width of the paper are automatically detected. Therefore, the paper size detection unit 114 also functions as the actual size input unit 871.

  In addition, when printing with a printer using electrophotography, reduction printing and enlargement printing are often performed, but at that time, depending on the printing machine, the specific area of the paper is small but different from others. It may become a reduced size or an enlarged size. This is referred to as the “癖” of the printing press. Therefore, in order to deal with such “癖”, in addition to the correction unit 880 described above, a unit for dividing the sheet surface area and setting the correction condition of the processing position for the specific division may be employed. Thereby, the processing position corresponding to the different reduction or enlargement in the specific area can be corrected.
