Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control method for cutting an image-forming roll paper for each drawing area in an automatic drafting machine equipped with a cutting device.

[Conventional technology]

The roll paper is rotatably supported on one side of the table, the roll paper feeding means is provided on the other side of the table, the paper cutting means is provided on the paper feeding side of the feeding means, and the roll paper feeding means is driven to drive the table. In an automatic drafting machine that supplies roll paper to the top, after drawing is completed in the drawing area of the roll paper, the roll paper is separated from the other end of the drawing area and the cutting position 2 as shown in FIG. M
The roll paper 4 is moved in the feeding direction by a distance corresponding to, and the roll paper is cut at the moving position. Therefore, as is clear from FIG. 5, dead spaces C and D in which printing is not performed are formed on the cut paper, and the spaces C and D
D is manually disconnected.

[Problems to be solved by the invention]

As described above, when the roll paper is fed by the distance M, a dead space is formed in the cut paper, and this space has to be cut manually.

The present invention aims to eliminate the above defects.

[Means for solving problems]

In order to achieve the above object, the present invention rotatably supports roll paper on one side of a table, provides roll paper feed means on the other side of the table, and provides paper cutting means on the paper feed side of the feed means. An automatic drafting machine in which roll paper is supplied onto a table by driving the roll paper feeding means and is drawn by a drawing head that moves in XY directions relative to the paper on the table. After the paper is drawn in the drawing area, the roll paper is moved in the feeding direction by a distance corresponding to the distance A between the one end of the drawing area on the paper feeding direction side and the paper cutting position, and the one end of the drawing area and the paper cutting are cut. The step of matching the positions, the step of cutting one end of the drawing area, and the roll paper to a value obtained by subtracting the above A from the total length 1 of the drawing area in the feeding direction. Feed moves in a direction only those to a distance B,
And a step of setting a next drawing area on the table.

[Action]

When the drawing in one step is completed, the roll paper moves in the feeding direction by the distance A, whereby one end of the drawing area of the roll paper reaches the cutting position and one end of the drawing area is cut.

Next, when the sheet is moved by the distance B in the feeding direction, the other end of the drawing area of the paper coincides with one end of the drawing area of the automatic drafting machine. As a result, no dead space is formed between the roll paper drawing area and the next drawing area.

〔Example〕

Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

In FIG. 4, 10 is the table of the automatic drafting machine,
Shafts 16 and 18 for detachably supporting a core body 14 on which roll paper is wound are rotatably supported by the machine body 12 on one side. A tension shaft 20 is rotatably supported by the machine body 12, and a guide shaft (not shown) is rotatably supported below the tension shaft in contact with the shaft 20. Reference numeral 22 denotes a feed drive roller rotatably supported by a machine body 24 on the other side of the table 10, and a pinch roller shaft having a pinch roller 26 fixedly mounted on the machine body 24 is rotatably supported by the drive drive roller 22. ing. The roller 22 is linked to the output shaft of a motor 28. The rollers 22 and 26 and the motor 28 constitute a paper feeding means. A cutting device 30 is composed of a rotary cutter rotatably arranged on the machine body 24, and is linked to a drive motor 32. Reference numeral 34 is a Y rail, and 36 is an image forming head, which are driven in the XY directions on the table 10 by an XY motor 38.

The XY motor 38, the cutter drive motor 32, the paper feed motor 28, and the writing tool lifting solenoid 40 built in the head 36 are connected to the output end of a controller 42 composed of a microcomputer, and drawing data is input to the input end of the controller 42. Output host computer 44
Are connected. A sheet feed control program, which will be described later, is written in the ROM of the controller 42.

In the above-described configuration, first, the roll paper is manually fed out from the core body 14 and placed on the table 10 through the tension shaft 20 and the guide shaft, and the leading end of the roll paper is inserted between the rollers 22 and 26. And then these rollers 2
The roll paper 46 is held between the sheets 2 and 26 (Fig. 1A).

Next, the controller 42 is started to perform a predetermined drawing on the drawing area of the paper 46 on the table 10.
After the completion of the first drawing, the controller 42 drives the motor 2 based on the paper feeding program written in the ROM.
8 is driven to move the roll paper 46 by A mm in the feeding direction (FIG. 1B). As a result, the one end side 46 a of the first drawing area of the paper 46 is located on the cutting execution line 48.
Next, the controller 42 determines whether or not the automatic drafting machine is an option with a cutter, and if it is with a cutter, cuts the paper 46, then moves Bmm and stops (FIG. 1C). This completes one sheet feeding process. Next, a predetermined drawing is performed on the second drawing area of the paper 46. When this drawing process is completed, the paper first moves in the Amm feed direction by the same operation as the above process (first
(D) After cutting the paper, move in the Bmm feed direction and stop. The above Amm is the distance between the sheet feeding direction side end 50 of the drawing area of the automatic drafting machine and the paper cutting execution position 48, and the above Bmm is the total length of the drawing area, that is, one sheet of paper after cutting. When the total length is 1 mm, (1 mm
-Amm), and these values A and B are stored in the RAM of the controller.

〔effect〕

As described above, according to the present invention, the roll paper is cut for each drawing area, so that the paper can be effectively and economically used.
