In the paper processing apparatus 1 according to the present invention, in addition to the control method for various processing jobs set and registered as the normal mode, there are two modes: an "autocut mode" and a "layout review mode" for reviewing the settings. It has a control mode.

(Overview of auto cut mode)
6, when the front and rear margin portions 15c and 15d of the product 14 on the paper 100 are wide, the front and rear margin portions 15c and 15d are divided into a plurality of portions 15cc and 15dd, and are cut into predetermined portions. Cut finely in the following narrow widths. As shown in FIG. 3, the cut piece on the leading edge side of the paper falls from between the upper and lower blades 34a and 34b of the cutting blade 34 and the downstream transport roller 5b as indicated by an arrow 82, and is placed under the drop space. are collected in the collection box 11. Similarly, the cut pieces on the rear end side of the paper fall from between the upper and lower blades 34a and 34b of the cutting blade 34 and the upstream transport roller 5a as indicated by an arrow 80, and are collected in a collection box located below the drop space. Collected at 11. Whether or not the front and rear margin portions 15c and 15d in the transport direction are to be divided and cut depends on the dimensions A1 and A2 of the margin portions 15c and 15d in the transport direction calculated based on the total length L of the paper 100 and the cut position data, and the cut pieces. are compared with the dimensions X, X in the conveying direction F of the falling spaces 71, 73, and are automatically finely cut into narrow widths equal to or less than a predetermined width so that A1≤X and A2≤X. For example, when the dimension X in the conveying direction of the space in which the cut pieces fall is 15 mm, the dimension to be divided and cut is controlled in units of 10 to 15 mm.

In the present embodiment, the dimensions of the cut piece drop space 71 and the drop space 73 in the conveying direction F are the same size X, but they may be different sizes X1 and X2, respectively. In this case, the shorter dimension of X1 and X2 may be set to X and compared with A1 and A2.

The margins 15a and 15b can be processed by, for example, using two vertical cutting units described above to simultaneously cut the paper 100 in the transport direction.

(layout review mode)
In the layout review mode, a sheet of paper to be cut based on cutting information such as cutting conditions, crease conditions, slit conditions, optional processing conditions (formation of chamfers and formation of perforations), etc. When there is a margin portion having a transport direction dimension to be executed in the auto cut mode such that the transport direction dimension (A)>the transport direction dimension (X) of the drop space of the margin portion, division in the auto cut mode is performed. A mode in which the distribution of the transport direction dimensions of each margin portion excluding the product is reviewed as a whole while the dimensions of the product in the cutting information remain unchanged so as to reduce the number of times of cutting, After the review, if there are still objects to be subjected to the autocut mode, the division cutting (autocut mode) is performed for that portion.

According to the above configuration, since the number of times the margin portion of the paper is divided and cut into short widths is kept to a necessary minimum, processing time longer than necessary is not required.

A specific embodiment of the autocut mode and layout "review mode" will be described later.

(Basic operation of paper processing apparatus 1)
Next, basic operations of the paper processing apparatus 1 will be described with reference to FIG.

In the paper processing apparatus 1 of FIG. 1, cutting conditions are set and registered using the operation panel based on individual cutting information regarding various processing jobs. Instead of the manual setting registration, or in cooperation with the manual setting registration, information regarding various processing jobs may be automatically set and registered by reading a bar code or the like with a CCD sensor.

When the operator presses the start button on the operation panel, a series of sheet processing operations are started, and a plurality of sheets 100 stacked on the sheet feeding table 30 of the sheet feeding unit 3 shown in FIG. 7, the sheets are supplied to the paper transport path 10 one by one from the top.

In the first processing unit 20 and the second processing unit 21, a plurality of slit lines, perforations, and folds parallel to the paper transport direction T are formed on the paper 100, and perforations extending in the horizontal direction orthogonal to the paper transport direction T are formed. and creases are formed in the paper 100 .

In the cutting section 5, the paper 100 is conveyed toward the cutting blade 34 by the upstream roller pair 5a, and the paper 100 is nipped by at least one of the upstream roller pair 5a and the downstream roller pair 5b. The paper 100 is cut in the horizontal direction orthogonal to the paper transport direction T at predetermined cutting positions in order from the downstream side. In the cutting section 5, the cut product (printed portion) is transported downstream by the downstream roller pair 5b and collected on the discharge tray 19, while the cut margins and small fragments are collected. , is discharged to the trash can 11 below.

Next, a procedure for registering processing jobs (cutting conditions) in the sheet processing apparatus 1 will be described with reference to FIGS. 7 and 8. FIG.

In FIG. 7, the controller 6 temporarily registers the size P of the paper 100 in the paper transport direction T in the RAM (step S10). Next, the control unit 6 temporarily registers in the RAM cutting conditions, crease conditions, slit conditions, optional processing conditions (formation of chamfering and formation of perforations) based on the cutting information (step S12). As shown in FIG. 8, in the cutting condition registration job, the cutting conditions are input (step S20), the control section 6 determines the cutting conditions (step S22), and ends the cutting condition registration job.

The cutting conditions to be input include, for example, the total width and length of the paper, its characteristics (thickness, hardness, etc.), the dimensions of the margins, the number of horizontal and vertical divisions of the area left after the main printing area is printed, and the like. It is a combination of individual cutting information.

According to the above configuration, the cutting information input means is provided, and by inputting the cutting information, it is possible to cut the paper to a desired size according to the paper. It is also possible to appropriately correct the cutting conditions while viewing the cutting state on the preview display.

Another configuration preferably includes cutting condition display reading means for reading the cutting condition display printed on the paper as to how the paper is to be cut. The control means controls the operations of the conveying means and the cutting means based on the cutting conditions read by the cutting condition display reading means.

The cutting condition display printed on the paper can be composed of, for example, a bar code, an array of symbols, or the like. The cutting condition display reading means includes, for example, an imaging sensor that captures an image of the cutting condition display, an optical sensor that determines the brightness, color, position, size, etc. of the cutting condition display, as well as printing using ink containing a magnetic component. If so, a magnetic sensor or the like that detects magnetism can be used.

According to the above configuration, it is possible to cut the paper based on the cutting condition display pre-printed on the paper, saving the trouble of inputting the cutting information.

Next, the cutting condition determination job in step S22 of FIG. 8 will be described in detail with reference to FIGS.

First, the control unit 6 determines that the dimension A (A1) of the margin portion 15c in the transport direction and the dimension A (A2) of the margin portion 15d in the transport direction are equal to or less than the dimension X in the transport direction F of the falling space for the cut pieces. It is determined whether or not (step S30). If both the dimension A (A1) of the margin portion 15c in the transport direction and the dimension A (A2) of the margin portion 15d in the transport direction are equal to or less than the dimension X in the transport direction F of the falling space of the shredded pieces, the controller 6 determines the cutting conditions for the deliverable 14;
If at least one of the dimension A (A1) of the margin portion 15c in the conveying direction and the dimension A (A2) of the margin portion 15d in the conveying direction is larger than the dimension X in the conveying direction F of the falling space for the cut pieces , in step S32, the "review mode" is executed, and the control unit 6 determines cutting conditions for the product 14. FIG.

(Layout "Review Mode 1")
In FIG. 9, "review mode 1" will be described as one specific example when execution of "review mode" is selected (step S32).

In FIGS. 6 and 10, for example, when the dimension A (A1) in the transport direction of the margin portion 15c is larger than the dimension X in the transport direction F of the falling space of the cut pieces, the dimension A in the transport direction of the margin portion 15c (A1) is larger than the dimension X in the transport direction F of the falling space of the cut pieces, so the transport direction dimension A (A1, A2) of each margin portion (15c, 15d) excluding the product is distributed. is notified to the operator to review (step S40).

According to the above configuration, the operator is given an opportunity to re-examine the layout of the margin portion where division cutting is performed by resetting by manual input, and depending on the contents of the resetting, the processing time of the autocut mode can be shortened. can. Incidentally, at the time of notification, a warning may be displayed on the operation panel, or a warning sound such as a buzzer may be emitted.

Reviewing the distribution of the dimensions in the transport direction of each margin portion excluding the product means that the dimensions of the product in the cutting information are kept as they are so as to reduce the number of divisional cuts in the auto-cut mode. This refers to the overall review of the distribution of the transport direction dimensions of each margin portion excluding objects.

Specifically, in FIG. 6, for example, in the layout before the review, when the product 14 is shifted to one side of the paper transport direction and A1≦X and A2>X, the margin portion 15d Auto cut mode will be executed only for . The processing time required for cutting is increased by the processing time of the auto-cut mode for the margin portion 15d.
However, as for the layout after review, for example, when the product 14 is arranged in the center of the paper transport direction and A1≦X and A2≦X, both the margin portions 15c and 15d are auto-cut. As a mode, no division cutting is performed. According to the above configuration, the processing time required for the cutting process is the shortest.

In step S42, if the operator does not review the layout in response to the question "Review the layout?"

If the layout is to be reviewed in step S42, the operator re-inputs the cutting conditions with a layout that satisfies A1≤X and A2≤X as much as possible in step S44, and terminates the layout "review mode 1".

(Layout "Review Mode 2")
In FIG. 9, "review mode 2" will be described as another specific example when execution of "review mode" is selected (step S32).

In FIGS. 4A and 11, for example, if the dimension A (A2) of the margin portion 18b in the transport direction is larger than the dimension X in the transport direction F of the falling space of the cut pieces, the dimension A of the margin portion 18b in the transport direction The transfer direction dimensions A (A1, A2, A3) of the margins (18a, 18b, 18c) are automatically sorted so that (A2) is equal to or less than the dimension X in the transfer direction F of the falling space of the cut pieces. Review to According to the above configuration, it is possible to reduce the size of the paper processing apparatus as a whole, and to minimize the number of times of dividing and cutting the margin portion of the paper so as not to require an excessive processing time.

Reviewing the allocation of the dimensions in the transport direction of each margin portion excluding the product means that the dimensions of the product (16, 17) in the cutting information are left as they are so as to reduce the number of divisional cuts in the autocut mode. In this state, the distribution of the transport direction dimensions of the margins excluding the product is wholly reviewed.

Specifically, in FIG. 4A, for example, in the layout before review, the deliverables 16 and 17 are located near both ends of the paper, and A1≦X, A2>X, and A3≦X. , the control unit 6 makes the dimensions A (A1, A2, A3) of the margins 18a, 18b, 18c in the conveying direction as far as possible less than or equal to the dimension X in the conveying direction F of the falling space of the shredded pieces. automatically review the layout of each margin (step S50). For example, in FIG. 4B, the distribution is performed so that the dimension of the margin portion in the transport direction is A1′=A2′=A3′=1/3×(A1+A2+A3) (step S52).

The control unit 6 automatically re-inputs the reviewed data (A1', A2', A3') as the cutting conditions, and terminates the "review mode 2".

When A1′≦X, A2′≦X, and A3′≦X are satisfied as the layout after the review, the margin portions 18a, 18b, and 18c are set to the auto-cut mode, and division cutting is not performed at all. Therefore, processing time can be shortened.

(Layout "Review Mode 3")
In FIG. 9, "review mode 3" will be described as another concrete example when execution of "review mode" is selected (step S32).

4A and 12, for example, when the dimension A (A2) in the transport direction of the margin portion 18b is larger than the dimension X in the transport direction F of the falling space of the shredded pieces, the dimension A in the transport direction of the margin portion 18b The transfer direction dimensions A (A1, A2, A3) of the margins (18a, 18b, 18c) are automatically sorted so that (A2) is equal to or less than the dimension X in the transfer direction F of the falling space of the cut pieces. Review to

Reviewing the allocation of the dimensions in the transport direction of each margin portion excluding the product means that the dimensions of the product (16, 17) in the cutting information are left as they are so as to reduce the number of divisional cuts in the autocut mode. In this state, the distribution of the transport direction dimensions of the margins excluding the product is wholly reviewed.

Specifically, in FIG. 4A, for example, in the layout before review, the deliverables 16 and 17 are located near both ends of the paper, and A1≦X, A2>X, and A3≦X. teeth,
The control unit 6 controls the dimension A (A1, A2, A3) of the margins 18a, 18b, 18c in the conveying direction to be equal to or less than the dimension X in the conveying direction F of the falling space of the cut pieces as much as possible. , the layout of each margin portion (18a, 18b, 18c) is automatically reviewed so as to reduce the total number of times of division cutting (step S60). For example, compared to the case where the number of divisional cuts of each margin before review is A1=1 time, A2=3 times, and A3=0 times (total of 4 times), the number of times of divisional cutting after review is A1. The layout of each margin portion (18a, 18b, 18c) is reviewed so that '=1 time, A2'=1 time, and A3'=1 time (3 times in total). According to the above configuration, the processing time can be shortened more efficiently.

In FIG. 4B, the control unit 6 automatically re-inputs the reviewed data (A1', A2', A3') as the cutting conditions (step S60), and ends the "review mode 3".
(Layout "review mode 4")
In FIG. 9, "review mode 4" will be described as another concrete example when execution of "review mode" is selected (step S32).

5A and 13, for example, if the dimension A (A2) of the margin portion 28b in the conveying direction is larger than the dimension X of the space in which the shredded pieces are dropped in the conveying direction F, the control portion 6 controls each margin portion ( 28a, 28b, 28c, 28d) are set to predetermined values such that A≤X, and the dimensions of the products (25, 26, 27) are left as they are, the layout is automatically reviewed so as to shift the entire product to the downstream side in the conveying direction (step S70). According to the above configuration, it is easy for the operator to understand the content of the processing.

For example, in FIG. 5A, when the dimension X in the transport direction of the falling space of the cut pieces is 15 mm, the transport direction dimensions A (A1, A2, A3, A4) of the margins (28a, 28b, 28c, 28d) are set to , the predetermined value=10 mm.

In FIG. 5B, the control unit 6 automatically re-inputs the reviewed transport direction dimensions A1′=A2′=A3′=A4′=10 mm as the cutting conditions (step S72), and ends the “review mode 4”. . Regarding the processing of the rearmost margin portion 29, the transport direction dimension (A5) of the rearmost margin portion 29 is the inter-roller distance (X+X=2X) between the upstream roller pair and the downstream roller pair in the paper transport direction. ), it may be configured so that it is discharged from the same discharge route as the product (25, 26, 27) without being cut. According to the above configuration, the processing time can be shortened more efficiently. Alternatively, the operator may perform cutting using a separate cutting tool before or after the fact.

(Auto cut mode control)
After executing the layout "review mode" shown in FIGS. 10 to 13, next, in FIG. are not all A≤X), the auto-cut mode (divisional cutting) is executed only for the margin portions where A>X (step S82).

In step S80, if all the margins satisfy A.ltoreq.X, the autocut mode is terminated.
