JP2508343Y2 - Paper guide in flatbed type automatic drafting machine - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a paper guide in a flat bed type automatic drafting machine.

[Conventional technology]

In a flat bed type automatic drafting machine that supports paper on a table with a flat paper support surface, moves the pen head in parallel in the XY directions on the table surface, and prints on the paper on the table. It is known to use both cut paper and roll paper, in which the paper is developed on a table and drawn on the roll paper.

[Problems to be solved by the invention]

When drawing on a roll paper, the roll paper is supplied onto the table from a roll paper supply means arranged facing one side of the table, and a roll paper winding arranged opposite the other side of the table. It is taken up by the take-up means. The roll paper is spread all over the table in the longitudinal direction. Therefore, when an object protruding from the table surface is placed on the table,
The roll paper rides on this object and rises above the table surface. On the other hand, a flat bed type automatic drafting machine may support a cut sheet on a table and perform drawing on the cut sheet. The cut sheet needs to be set accurately at a predetermined position on the table. When the cut paper is aligned with the predetermined position on the table, it is not possible to provide the paper guide protruding on the table as described above. Therefore, a line for aligning the paper is provided at the predetermined position on the table. The only way to align the corners of the cut paper with the line was. However, according to this method, it was difficult to align the cut sheet with the alignment line. The present invention is intended to eliminate the above defects.

[Means for solving problems]

In order to achieve the above object, the present invention forms a groove 22 parallel to the XY coordinate axes on the table 4 at a reference position outside the drawing range of the table 4, and forms a paper guide plate 24 in the groove 22.
It is made to project from 22 and is detachably fitted.

[Action]

By bringing the cut paper into contact with the paper guide plate 24 protruding from the table 4, the cut paper can be easily adjusted to the reference position on the table 4, and when the roll paper is spread on the table 4. The paper guide plate 24 can be removed from the groove 22.

〔Example〕

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

Reference numeral 2 denotes a flat bed type automatic drafting machine, in which a known electrostatic adsorption type table 4 is fixedly mounted on the machine body, and a movable rail 6 is provided on the upper and lower edges of the table 4 via a rail guide mechanism (not shown). Both ends of the are linked to the X drive system and are slidably supported. A pen head 8 is movably attached to the movable rail 6 in association with a Y drive system. Reference numeral 10 is a roll paper supply means disposed adjacent to one side of the table 4, and includes roll paper support shafts 12 and 14 for rotatably supporting a core of the roll paper, and a guide shaft 16. ing. On the other side of the table 4, a roll paper winding means 20 having a roll paper winding shaft 18 linked to a drive system is disposed adjacent to the other side of the table 4. Positioning grooves 22 are formed in an L shape in plan view at the front edge portion and the left side edge portion of the table 4 which are located outside the effective drawing area. The groove 22 formed along the front edge of the table 4 is set parallel to the X coordinate axis set on the table 4, and the groove 22 formed along the left side edge of the table 4 is , Is set parallel to the Y coordinate axis set on the table 4. The wall surface of the groove 22 is made of a magnetic material. A paper guide plate 24 made of a thin L-shaped strip having a magnetic force is detachably fitted into the groove 22 so as to slightly protrude from the groove 22, and is closely attached by the magnetic force. The orthogonal portion 24a of the guide plate 24 constitutes a paper placement reference point. The wall side of the groove 22 of the table 4 may be made of a magnet, and the paper guide plate 24 may be made of a magnetic material.

In the above configuration, when setting the cut sheet 26 on the table 4, the cut sheet 26 can be easily placed on the table 4 by aligning the corner of the cut sheet 26 on the alignment side with the orthogonal portion 24a of the guide plate 24. It can be accurately set at a predetermined setting position. When performing drawing work using roll paper, remove the guide plate 24 from the groove 22 and remove the guide plate 24 from the roll paper placement path so that the guide plate 24 does not interfere with the roll paper placement. .

〔effect〕

As described above, according to the present invention, the paper guide plate for aligning the paper can be removably arranged on the table, so that the cut paper can be easily aligned on the table. When using the roll paper, there is an effect that the paper guide plate is removed from the table, thereby preventing the roll paper from riding on the paper guide plate and floating from the table surface.
