Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control method for cutting roll paper for drawing into drawing areas in an automatic drawing machine equipped with a cutting device.

[Conventional technology]

A roll paper is rotatably supported on one side of the table, a roll paper feeding means is provided on the other side of the table, a paper cutting means is provided on the paper feeding side of the feeding means, and the roll paper feeding means is driven. In an automatic drawing machine that feeds roll paper at the top, after completing drawing on the drawing area of the roll paper, the distance between the other end of the drawing area and cutting position 2 is determined by cutting the roll paper as shown in Figure 5. 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 6. Therefore, as is clear from FIG. is formed, and this space C,
D is cut manually.

[Problem that the invention seeks to solve]

As mentioned above, if the roll paper is sent a distance M.

A dead space is formed in the paper after cutting, and this space must be manually cut, which is a hassle.

The present invention aims to eliminate the above-mentioned defects.

[Means to solve problems]

In order to achieve the above object, the present invention rotatably supports a roll paper on one side of the table 1.

In this apparatus, a roll paper feeding means is provided on the other side of the table, a paper cutting means is provided on the paper feeding side of the feeding means, and the rolled paper is fed onto the table by driving the roll paper feeding means. , After completion of drawing in the drawing area of the roll paper on the table, move the roll paper in the feeding direction by a distance corresponding to the distance A between one end of the drawing area on the paper feeding direction side and the paper cutting position, and complete the drawing. After cutting one end of the area, the roll paper is
The drawing area is moved in the feeding direction by a distance B corresponding to the value obtained by subtracting the above A from the total length in the feeding direction.

[Effect]

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

One end of the drawing area is cut off.

Next, when the sheet is moved by a 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. This prevents dead space from being formed between the drawing area of the roll paper and the next drawing area.

〔Example〕

The structure of the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

In FIG. 4, 10 is a table of an automatic drafting machine,
On one of these bodies 12, shaft bodies 16 and 18 for removably supporting a core body 14 around which a roll paper is wound are rotatably supported. A tension shaft 20 is rotatably supported by the body 12, and a guide shaft (not shown) is rotatably supported below this in contact with the shaft 20. 22 is a feed drive roller rotatably supported by a body 24 on the other side of the table 10, and in contact with this, a pinch roller shaft having a pinch roller 26 fixed thereon is rotatably supported by the body 24. ing. The roller 22 is linked to the output shaft of a motor 28. The rollers 22, 26 and the motor 28 constitute paper feeding means. 30 is a cutting device consisting of a rotary cutter rotatably disposed on the body 24, and linked to the drive motor 32. 34 is a Y rail, and 36 is a drawing head, which are driven by an XY motor 38 in the XY directions on the table 10.

The above-mentioned XY motor 38, power, twine drive motor 32, paper feed motor 28, and writing instrument lifting solenoid 40 built into the head 36 are connected to the output end of a controller 42 consisting of a microcomputer, and the input end of the controller 42 is connected to the input end of the controller 42. Host computer 4 that outputs data
4 is connected. A paper feed control program, which will be described later, is written in the ROM of the controller 42.

In the above configuration, first, the roll paper is manually fed out from the core body 14, passed between the tension shaft 20 and the guide shaft, and placed on the table 10, and the leading end of the roll paper is inserted between the rollers 22 and 26. These rollers 22
26 to hold the roll paper 46 (FIG. 1A).

Next, the controller 42 is started and a predetermined drawing is performed in the drawing area on the table 10 of the paper 46.

After the first drawing is completed, the controller 42 controls the motor 2 based on the paper feeding program written in the ROM.
8 to move the roll paper 46 by Am, m in the feeding direction (as shown in Figure 1). As a result, when one end side 46a of the first drawing area of the paper 46 is located on the cutting line 48, the controller 42 determines whether the automatic drafting machine is an option with a cutter and If so, after cutting the paper 46, it moves Bmm and stops (Fig. 1C). This completes one step of paper feeding. Next, draw the prescribed drawing in the second drawing area of the paper 46. Enforce.

When this drawing process is completed, the paper is first moved in the Amm feeding direction (FIG. 1-2) by the same operation as the above process, and after cutting the paper, it is moved in the Bmm feeding direction and then stopped. The above Amm is the distance between the paper feeding direction side end 50 of the drawing area of the automatic drafting machine and the paper cutting position 48, and the above Bmm is the total length of the drawing area, that is, the length of one sheet of paper after cutting. When the total length is J, mm, (im
m-Amm), and these values A and B are stored in the RAM of the controller.

〔effect〕

As described above, in the present invention, since the roll paper is cut for each drawing area, there is an effect that the paper can be used effectively and economically.
