Abstract

(57) [Summary] [Purpose] The sheet material is firmly fixed to the seat support surface so that it does not shift during drawing or cutting. [Structure] The upper horizontal portion of the conveyor belt 22 constitutes a sheet supporting surface 22a, on which a sheet material 28 is placed. The head 12 moves in the XY coordinate axis directions with respect to the sheet material 28 on the sheet supporting surface 22a, and the pen 14 or the cutter 16 draws or cuts the sheet material 28. The sheet supporting surface 22a is provided with a sheet fixing portion 30 composed of an adhesive application surface or a sandpaper-like granular convex convex surface, and by the sheet fixing portion 30,
Both sides of the sheet material 28 are fixed to the sheet supporting surface 22a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plotter for drawing or cutting a sheet material, and more particularly to a plotter capable of fixing the sheet material on a sheet supporting surface so as not to shift.

[0002]

[Prior art]

 BACKGROUND ART A plotter that fixes a sheet material to a sheet supporting surface by a vacuum force when drawing or cutting the sheet material is conventionally known. It is also known to cover the cloth with an airtight sheet of vinyl or the like for the purpose of enhancing the vacuum force, especially in the case of cutting the cloth.

[0003]

[Problems to be solved by the device]

 In a plotter in which a sheet material is fixed on the sheet support surface by a vacuum force and drawing or cutting is performed on this sheet material, the vacuum force acting on the sheet material is higher in the central portion of the sheet material than in the end portion. . Therefore, if drawing or cutting is performed on the edge of the sheet material, the sheet material may be displaced due to the pen pressure of the pen or the cutter. This shift phenomenon is likely to occur when cutting a soft cloth. The present invention aims to eliminate the above defects.

[0004]

[Means for solving problems]

 In order to achieve the above-mentioned object, the present invention controls the relative movement of the head in the XY coordinate axes on the sheet supporting surface, and draws or cuts on the sheet material on the sheet supporting surface with a pen or a cutter provided on the head. In the plotter configured to perform the above, a sheet fixing portion for adhering the sheet material to the sheet supporting surface is provided at a portion of the sheet supporting surface that supports at least both sides of the sheet material.

[0005]

When the sheet material is placed on the seat supporting surface, both side ends of the sheet material are fixed to the seat fixing portion provided on the seat supporting surface. As a result, when drawing or cutting is performed on the sheet material, the sheet material does not shift from the sheet supporting surface.

【Example】

 Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. Numeral 2 is a plotter for drawing and cutting, and X rails 6, 8 are fixedly installed on both sides of the machine body 4, and Y rails 10 are movably installed in parallel on the merails 6, 8. A head 12 is movably attached to the Y rail 10, and a pen 14 and a cutter 16 are supported by the head 12.

Belt support rollers 18, 20 are rotatably supported at the front and rear of the machine body 4, and a rubber conveyor belt 22 is stretched between the rollers 18, 20. The upper horizontal portion of the conveyor belt 22 constitutes a sheet supporting surface, and a known vacuum table 24 is arranged below the upper horizontal portion.

In order to exert the vacuum force of the vacuum table 24 on the sheet material on the conveyor belt 22, the sheet supporting surface 22 a of the conveyor belt 22 is provided with a large number of small vent holes (not shown). A paper feed roller 26 is rotatably provided in front of the machine body 4, and a roll portion 28a of a sheet material 28 is supported by the paper feed roller 26. The Y rail 10 is connected to an X driving device (not shown), and the head 12 is connected to a Y driving device.

The XY drive device, the pen lift drive device, the cutter lift drive device, the cutter rotation control device, the conveyor belt drive device, the vacuum drive device, etc. are connected to a controller and are configured to be controlled by the controller. There is. Sheet fixing portions 30 are provided on both sides of the conveyor belt 22 over a predetermined range.

The sheet fixing portion 30 is formed by applying a non-migrating adhesive to a predetermined range on both sides of the sheet supporting surface 22 a of the conveyor belt 22. The sheet fixing portion 30 may be any one as long as it prevents the sheet material (paper, cloth, etc.) from being displaced, and may have a high friction granular uneven surface such as sandpaper, in addition to the adhesive application surface.

In the above-described structure, the sheet material 28 pulled out from the paper feed roller 26 onto the upper horizontal portion of the conveyor belt 22 and placed on the sheet material 28 is pulled by the suction force of the vacuum table 24. The sheet material 28 is fixed on the sheet support surface 22a, and both side ends of the sheet material 28 are firmly fixed on both sides of the sheet support surface 22a by the sheet fixing portions 30 of the sheet support surface 22a.

The sheet material 28 on the conveyor belt 22 is drawn or cut by the pen 14 or the cutter 16. After drawing or cutting, the conveyor belt 22 is driven to feed the sheet material 28 onto the new sheet supporting surface 22a.

In the above embodiment, the present invention is applied to a plotter that draws or cuts on one sheet material. As shown in FIG. 4, the present invention is applied to a cloth 32 and a carbon paper 34. It is also possible to apply three sheets of the pattern paper 36 to each other and spread them on the conveyor belt 22 to fix them on the conveyor belt 22, and apply them to a sheeting plotter for drawing and cutting.

Further, the sheet fixing portion on the conveyor belt 22 does not necessarily have to be the both end portions of the conveyor belt, and the sheet fixing portion 30 may be provided at the central portion of the conveyor belt 22 as shown in FIG. .

As shown in FIG. 5, by providing a plurality of sheet fixing portions 30 in the central portion of the conveyor belt 22, it is possible to deal with sheet materials 28 having different width sizes. Further, the entire surface of the conveyor belt may be used as the sheet fixing portion, but in that case, it is necessary to use a weakly adhesive adhesive or to form an uneven sandpaper surface that does not affect drawing or cutting.

In implementing the present invention, the sheet material may be fixed on the conveyor belt only by the fixing force of the sheet fixing portion without using the vacuum table.

[0015]

【effect】

 Since the present invention is configured as described above, it is possible to prevent deviation of the sheet material and perform good drawing or cutting. It is especially suitable for sheeting plotters that cut and draw on cloth.
