Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printed matter cutting device that performs cutting corresponding to the picture feathers of printed matter.

[Prior art] In order to create a paper box or the like from printed materials such as proofs, cardboard, corrugated cardboard, or the like with a pattern already printed on it is set in a sheet cutting device, the paper box is cut out into a flat shape, and the paper box is assembled. Normally, this sheet cutting device is equipped with a flat table and a cutting head that moves on the table in the X and Y directions to cut the sheet, and separates the sheet placed on the table. It is configured to cut based on the created cutting data. In this case, alignment is required in order to match the cutting line to be output with a cutting line corresponding to a pattern that has already been formed. Conventionally, in order to accomplish this task, first, before cutting based on the cutting line, another sheet was placed on the same table and the same line as the cutting line was output on a plotter to estimate the approximate position. After that, printed sheets such as proofs were placed to fit the position and the cutting was done.

[Problems to be solved by the invention] However, in the above-mentioned work, positioning work etc. is left to the senses of the operator, so it is not only impossible to achieve high accuracy, but also cutting errors may occur. This occurs in many cases, and trial and error is required, resulting in poor workability.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problem, and in a printed matter cutting device that performs cutting corresponding to the pattern of printed matter, the mechanical origin of the cutting device is means for storing cutting data expressed in a coordinate system with the origin as the origin; a table having ruled lines formed vertically and horizontally at regular intervals and on which printed matter to be cut is placed;
Positioning the printed matter according to one of the ruled lines and placing it on the table, moving the origin of the cutting data by a distance from the machine origin of the ruled line used for positioning, and moving the origin of the cutting data by the distance from the machine origin of the ruled line used for positioning; This is a printed matter cutting device characterized by comprising means for cutting printed matter by driving a cutting head having a cutter blade based on cutting data.

[Operation] With the above-described configuration, when generating a cutting line corresponding to the pattern of a printed matter, it is possible to output it to a desired position.

[Example 1] Figures 1 and 2 are a plan view and a side view of a cutting device according to the present invention.

1 is a table on which a sheet to be cut is placed, and a mat 2 is placed on the surface of the table so that it will not be damaged even if a cutter blade, which will be described later, comes into contact with the table. The mat 2 has ruled lines 14 on a grid for positioning at regular intervals (for example, 10 cm), and small holes (
(not shown) is provided.

Y-axis seal 11.
11 is installed, and one X-axis seal 12 is temporarily installed on this Y-axis line 11.11. X-axis seal 1
A cutting head 3 is attached to 2. X
The shaft seal is movable on the Y-axis seal by the Y-axis motor, and the head 3 is movable along the X-axis by the drive of the X-axis motor.As a result, the head 8 moves on the table in the XY direction. It is possible to move to. Further, reference numeral 13 is an operation key for instructing the start and end of an operation, inputting numerical values, etc.

The cutting head 3 includes a cutter blade 4, a drawing pen 5,
and a creasing blade 6 for shaping the bending line, each of which can be selectively operated.

Next, the data processing circuit of the cutting device according to the present invention will be explained based on FIG. FIG. .beta. is a block diagram of the processing circuit, in which the CPU 22 performs arithmetic processing on data based on the program stored in the ROM 23 and controls the operation. The RAM 24 stores data for arithmetic processing, and is used by the CPU 22 .
The ROM 23 and RAM 24 are connected to the pass line 21 along with the operation keys 13 described above. In addition, the above-mentioned
The axis motor 26 and the Y-axis motor 26 are connected to the pass line 21 via a motor driver 27, and in order to know the position of the cutting head, the Pulse signals from the encoder 28 and Y-axis encoder 29 are input to counters 30 and 31, and signals from the counters are input to the pass line 21 as coordinate information.

Furthermore, in this embodiment, a machine origin return button is used as an input device to cause the cutter to execute the return of the gunting head to the mechanical origin, and a machine origin return button is used to determine the origin of the coordinate system of the cutting data (hereinafter referred to as program origin 41). It is assumed that a program origin movement button is provided as an input device for this purpose. In this case, the position of the program origin 41 in the absolute coordinate system is determined by inputting the amount of relative movement from the previous program origin.

FIG. 4 is a diagram showing the difference between a coordinate system (hereinafter referred to as an absolute coordinate system) whose origin is the machine origin on the table of the cutter and a coordinate system possessed by cutting data.

The ROM 23 also stores a program for moving the origin shown as a flowchart in FIG.

Note that the initial setting value may be changed to another value depending on convenience.

The case where the origin movement operation shown in FIG. 5 is performed based on this program will be explained using FIG. 6. First, press the program origin movement button and enter X = 100 and Y = 50 as the relative movement amount, then the program origin 41 will be (X, Y) = (100,
50).

Next, press the program origin movement button again and set the relative movement amount to X=50. If Y = 100 is input, the program original J:L41 will move by that amount, and as a result, the value of (X, Y) = (150, 150) will be obtained in the absolute coordinate system. When pressed, program origin 41
is forcibly returned to the machine origin 40. In addition, in this case, the coordinate values of the program origin 41 in the absolute coordinate system are stored in the RAM 24.
When outputting cutting data, the stored X is stored in the cutting data.

Just add the value of Y.

Next, a method of cutting a printed matter according to its pattern using the cutting device having the above-mentioned configuration will be described in accordance with the flowchart shown in FIG. 11. As seen in FIG. 7, a white mat 2 is laid out on the cutter table l as described above, and ruled lines 45 are drawn at regular intervals (100 mm in this example) in the vertical and horizontal directions on this mat. There is. Also, the machine origin 40 is set to be at the lower leftmost position. Further, as shown in FIG. 8, registration cross marks 63, 64 are provided on the paper 50 on which the pattern 51 is printed to determine the program origin 41 in advance and to align the vertical and horizontal directions.
．． 65 and 66 are printed, and the intersection P of straight lines 63-65 and 64-66 is set to coincide with the program origin of this cutting data. In addition, there is a circular hole 53 in the center of the cross mark 63, 64, 65, 66.
．． 54. 55. In the figure with 5 degrees 6 open, the dashed line 52 indicates the line to be cut.Next, as shown in Figure 9, the paper 50 as described above is placed on the mat on table l. For the holes 53.55, the horizontal lines of the cross marks 63.65 and the horizontal ruled lines on the mat 2 are aligned, and for the holes 54.56, the vertical lines are similarly aligned. .

Figure 9 (DtL is the case where X=300.Y=200 (7) is aligned with the ruled line, so the coordinate value of point P in the absolute coordinate system is (X, Y) = (300, 200
), and since point P is the starting point that should be the program origin of the data to be output from now on, and the one program origin of the current data matches the initial setting value, that is, the machine origin, it corresponds to this printed matter. To output cutting data, perform the program origin movement described above.
In this example, press the program origin movement button, then
Input =300, Y=200. Next, based on this cutting data, the head 3 is driven to perform cutting.

This enables highly accurate cutting that corresponds to the pattern.

[Effects of the Invention] According to the invention as described above, highly accurate cutting corresponding to the pattern of printed matter can be performed with a simple operation.
