JPH0761630B2 - Paper cutting method and device for XY plotter - Google Patents

Description

The present invention relates to a sheet cutting method and apparatus for a sheet driving type XY plotter.

[Conventional technology]

In a paper-driven XY plotter, a special cutter unit is installed or a manual cutter is used to manually cut the paper at a predetermined position.

[Problems to be solved by the invention]

When the dedicated cutter unit is used, there is a defect that the control of the paper feeding becomes complicated and the structure of the dedicated cutter unit is complicated and expensive, and the manual operation has a defect that the work is troublesome.

The present invention aims to eliminate the above defects.

[Means for solving problems]

In order to achieve the above object, the present invention is a paper-driven XY plotter, in which the writing tool-type cutting tool held in the writing tool holding section of the writing tool stocker is held by the writing tool holding section of the drawing head when the paper is cut. The drawing head is moved in the direction traversing the paper, and the paper is cut by the cutting tool held by the writing tool holder of the drawing head.

[Action]

With the above configuration, the paper can be automatically cut without using a dedicated cutter unit, and the paper is cut along the movement locus of the image forming head, so that the positioning control of the cut portion of the paper can be performed. It can be done with simple control.

〔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. 5, reference numeral 2 denotes a machine body of a paper drive type XY plotter, in which a Y rail 6 is fixedly mounted on the paper placing plate 4 and horizontally to the machine. Both sides of the sheet 8 on the placing plate 4 are supported by a pinch roller mechanism composed of a driving roller 7 (see FIG. 1) and a pressing roller 9 arranged on both sides of the placing plate 4, and driven by an X motor. Drive roller 7
The paper 8 on the mounting plate 4 is moved back and forth (+ -direction) by rotating the
Sent to. An image forming head 10 is attached to the Y rail 6 so as to move along the Y rail 6 by driving a Y motor. Reference numeral 12 is a known writing tool holding portion provided on the drawing head 10, and the holding portion holds the drawing head 10
The pen is connected to a well-known pen lifting mechanism. A box 14 is provided on one end side of the Y rail 6, and a known rotary writing implement stocker (carousel) 16 is provided in the box 14. The writing instrument stocker 16
Is linked to an output shaft of a motor 18 with a speed reducer fixedly mounted on the box 14 as shown in FIG. This motor 18 is connected to a controller controlled by a computer. Writing tool holders 20 are formed at regular intervals on the horizontal portion of the stocker 16 which is composed of a pair of disks 16a and 16b.
A writing tool 24 is provided on the outer peripheral portion of the disks 16a and 16b of the stocker 16.
A groove for fitting and holding the peripheral surface of the pen is formed, and a pen stopper 25 is fixedly provided in the middle of the upper and lower grooves. A rotating arm 26 is rotatably supported by a shaft 28 on the disks 16a and 16b and is urged by a spring in one direction. The disc 16a,
The groove 16b, the pen stopper 25, and the rotating arm 26 constitute the writing tool holder 20. The writing tool 24 has its half-circumferential surface abutted against the wall surfaces of the grooves of the disks 16a and 16b and the wall surface of the pen stopper 24.
The flange portion of the writing instrument 24 is detachably fitted between the upper end of the pen stopper 25 and the lower surface of the disc 16a while being elastically contacted with the side surface of Has been done. A desired one of the writing tool holders 20 of the writing tool stocker 16 and the writing tool holder 12 of the drawing head 10 are configured so that the writing tools 24 can be automatically exchanged with each other. There is. still,
Since the structure for automatically changing the writing instrument is known, its detailed description is omitted.

In the above-described structure, the paper 8 is fed in the left-right direction in FIG. 1, that is, in the + -X direction, and the image forming head 10 is moved in the direction perpendicular to the paper surface in FIG. In the −Y direction, the writing tool 24 is brought into contact with the leading end of the writing tool 24 from above the paper 8 to a known drawing roller 30.
24 is fed along the drawing roller 30 in the + -Y direction by the feeding of the drawing head 10. As a result, predetermined drawing is performed on the paper 8.

In FIG. 1, reference numeral 32 is a writing instrument-type cutting instrument, and the writing portion 24 for the XY plotter has a flange 32a formed on the upper portion thereof.
It is set to have the same shape as that of the collar portion forming portion. On the upper end of the cutting tool 32, a rectangular angle regulation member 34 is fixed. At the lower end of the cutting tool 32, a paper pressing roller is
36 is rotatably supported, and the holder 38 of the paper pressing roller 36 is urged downward by a spring 40. The cutting tool 32 is provided with a stopper (not shown) that regulates the downward movement end of the holder 38. A cutter 42 is fixed to the cutting tool 32 at the side of the paper pressing roller 36 and in parallel with the paper pressing roller 36.
The cutting direction of 42 and the traveling direction of the paper pressing roller 36 are
The settings are the same. A cutter groove 44 is parallel to the longitudinal direction of the Y rail 6 and is longer than the lateral width of the paper 8 and is formed on the paper placing plate 4. An angle regulating member 46, which is located above the writing instrument holder 12 and has a concave portion that can be fitted into the angle regulating member 34, is attached to the elevating mechanism of the drawing head 10.

Next, the operation of this embodiment will be described.

Usually, the cutting tool 32 is the writing tool holder of the writing tool stocker 16.
Held at 20. When it is desired to cut the paper 8, the drawing head 10 holds the writing tool 24 held by the drawing head 10 in the writing tool stocker.
Then, the writing tool holder 12 of the drawing head 10 holds the cutting tool 32 held by the writing tool holder 20 of the writing tool stocker 16. At this time, the angle regulation member 34 of the cutting tool 32 is fitted to the angle regulation member 46 on the side of the imaging head 10,
The cutting direction of the cutter 42 is set parallel to the Y rail 6. The drawing head 10 is moved so that the cutter 42 is positioned directly above one end of the cutter groove 44, and the cutting tool 32 is placed at that position.
When is lowered, the cutter 42 fits into the cutter groove 44. Next, when the drawing head 10 is moved along the Y rail 6, the paper 8 is cut by the cutter 42 along the cutter groove 44. After the paper 8 is cut, the cutting tool 32 is lifted up, and then the cutting tool 32 is returned to the predetermined writing tool holding portion 20 of the writing tool stocker 16 and then the drawing operation is started.

[Effect] Since the present invention is configured as described above, there is an effect that the paper cutting operation can be performed with simple control and mechanism.
