Abstract

PURPOSE:To impart to a synthetic resin film an adhesive strength corresponding to the material and surface state of a base board and the material to be worked by forming a structure that different suction forces manifest at one face side and the other face side. CONSTITUTION:A precise coated face on which logarithmic fine suction holes are precisel distributed is formed by a coating agent having the logarithmic fine suction holes at one face 3a side of a synthetic resin film 3. Moreover, a compressional coated face on which this fine suction holes are compressionally distributed is formed by the coating agent having a lot of fine suction holes at the other face 3b side of this film 3. Thus different suction forces are manifested at the one face 3a side and the other face 3b side, and a desired material to be worked (a cutting sheet for instance) fixing film is obtained. Namely, this one face 3a is fixed to a base board with its adhesion and the cutting sheet is fixed to the other face 3b.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a film used for securing workpiece materials, such as canting sheets, to processing equipment, such as computer-controlled sheet cutting equipment.

[Prior Art] For example, in a sheet cutting device that automatically performs sheet canting under computer control, the following methods are available for fixing a canting sheet as a workpiece material onto a baseboard.

■ Items that use magnets: Place a canting sheet on top of a magnetic baseboard or baseboard, and then press the cutting sheet around the canting sheet with a paper guide to attach the cutting sheet to the baseboard. How to fix it.

■ Using electrostatic adsorption: A method of fixing the canting sheet by generating adhesion force due to static electricity on the baseboard surface.

- Using adhesive: A method in which the baseboard and the cutting sheet placed on this surface can be temporarily bonded and fixed using a removable adhesive.

■ Using double-sided tape: A method of adhesively fixing the cutting sheet placed on the surface of the baseboard using double-sided tape.

[The issue that the issue is trying to solve]

However, each of the above-mentioned means has the following problems.

■ Items using magnets: The canting sheet tends to lift up from the magnetic sheet or magnetic baseboard, resulting in poor fixation performance. When the cutting sheet is lifted, the tip of the canting ben that should be kept away from the cutting sheet may come into contact with the raised cutting sheet, and if the paper guide is placed incorrectly, the tip of the cutting pen may touch the raised cutting sheet. You may end up getting off the ground, which may narrow your work area.

Also, since 2 to 4 paper guides are required,
It takes time and effort to fix the cutting sheet, and it is unavoidable that the operation procedure becomes difficult when attaching and detaching the canting sheet.

■Those using electrostatic adsorption: When the physical properties of the cutting sheet change depending on the type of cutting sheet, it may not be possible to secure the sheet sufficiently depending on the range of the change or the thickness of the cutting sheet. Furthermore, when the temperature or humidity decreases (below 5°C or about 20%), the adsorption performance decreases.

■ Using an adhesive: With this method, after the canting sheet is peeled off from the baseboard, the canting sheet may curl or stretch due to the adhesive.

Furthermore, if this method is used repeatedly, the adhesive transfers from the base board to the cutting sheet, resulting in deterioration of the fixing performance, and if dust adheres to the fixing surface, it is difficult to restore the adhesive strength.

■ Using double-sided tape: Because it is difficult to remove double-sided tape from the canting sheet, double-sided tape cannot be used repeatedly.

[Means to solve the problem]

Therefore, in order to solve the above-mentioned problems, the present invention provides a fixing sheet that is interposed between a baseboard and a workpiece material in order to fix the workpiece material on the baseboard of a processing device. A coating agent having a large number of fine suction cup holes on one side of the resin film forms a dense coating surface in which the fine suction cup holes are densely distributed, and a coating material having a large number of fine suction cup holes on the other side forms a dense coating surface. Provided is a film for fixing a workpiece material, characterized in that the adhesive forms a coarsely and densely coated surface in which fine suction holes are distributed densely, thereby exerting different suction forces on one side and on multiple sides. It is something to do.

It should be noted that the densely coated surface and the coarsely coated surface formed on both sides of the synthetic resin film are determined by the difference in coating density of the coating agent having a large number of fine sucker holes or the number of fine sucker holes contained in the coating agent. Preferably, it is formed by. Further, it is also preferable that the formation is caused by a difference in the coating density of the coating agent having a large number of fine sucker holes, as well as the number of fine sucker holes contained in the coating agent.

Furthermore, it is also preferable that the densely coated surface and the coarsely coated surface formed on both surfaces of the synthetic resin film are formed by applying the coating agent to different positions on both surfaces.

[Effect]

In the synthetic resin film of the present invention, for example, polyester or the like can be used as a base film, and a urethane resin coating agent, which forms a large number of fine suction holes, is applied to both the front and back sides of the base film. . When these fine suction holes are pressed against the baseboard or the material to be processed, they exhibit a suction effect, resulting in close contact and adhesion to the baseboard or the material to be processed. The adhesion of these fine suction holes to the pressed smooth surface is very good, and the strength when pulled horizontally to the adhesive surface is very strong, but on the other hand, when pulled in the direction perpendicular to the adhesive surface, It peels off easily and there is no transfer of adhesive.

In the present invention, the strength of the adhesive force can be freely adjusted by applying a coating agent containing a large number of fine suction cup holes to both sides of the synthetic resin film so that the distribution density of the fine suction cup holes is different. , it is possible to impart different adhesion forces to the front and back surfaces of the synthetic resin film when it is used. This synthetic resin sheet is adhesively fixed in advance to the baseboard of the processing equipment with the densely coated surface where fine suction cup holes are densely distributed, that is, the surface to which a relatively strong adhesive force is applied, and then the material to be processed is attached. If it is attached to a coarsely coated surface with a dense distribution of minute suction holes, that is, a surface with a relatively weak adhesive force, the material to be processed will be fixed to the baseboard via the synthetic resin film and will not slide. Definitely prevented. Moreover, even if the material to be processed is pulled and peeled off from the baseboard, the synthetic resin film will not be peeled off from the baseboard, and only the material to be processed can be easily attached to and removed from the baseboard.

Also, when applying the adhesive to both sides of the synthetic resin film, if you apply the adhesive to different positions on both sides, the adhesive will not make the film thicker in some areas, allowing you to fix thin paper. You can work smoothly without creating any unevenness on the work surface.

The adhesive used in the present invention is bonded by the suction effect of the fine suction cup holes, so the adhesive does not transfer from the synthetic resin film to the baseboard or workpiece material when peeled off, and the adhesive surface is repeatedly Can be used. Moreover, if the adhesion force decreases due to sweat, dust, etc., the adhesion force can be restored by wiping it with a wet cloth.

〔Example〕

Next, a specific embodiment of the present invention will be described with reference to the drawings.

What is shown in FIG. 1 is a flat-head type cutter 1 as a processing device, in which the fixing film of the present invention is applied to fix a cutting sheet as a workpiece material. . As shown in FIG. 2, this cassotting pronotator 1 has a synthetic resin film 3 formed by applying a urethane resin adhesive having fine suction cup holes on both the front and back surfaces on a base hoard 2. Canting sheet 4 fixed by interposing
On the other hand, a Ben carriage 5 holds a cutting pen 6 and cuts out figures and characters under computer control.

As shown in FIGS. 3(a) and 3(b), dots of a coating agent are applied to both the front and back surfaces of the synthetic resin film 3, which is the fixing film of the present invention, by a technique such as silk screen printing. It is coated, and the adhesion is imparted by the adsorption action of fine suction holes contained in the coating agent. In addition,
The coating density of the coating agent is adjusted by the number of tondoors, and the distribution density of the fine sucker holes is different on both sides.

Of both sides of the synthetic resin film 3, FIG.
A surface 3a to be adhesively fixed to the spode 2 is shown, and a large number of dots 7 are applied, fine suction holes are densely distributed, and a relatively strong adhesive force is imparted.

FIG. 3(b) shows the surface 3b on which the cutting sheet 4 is fixed.
, the number of applied dots 7 is small, the fine suction holes are distributed densely, and a relatively weak adhesive force is imparted.

By interposing the synthetic resin film 3 of the present invention having different adhesion strengths on both sides, it is possible to reliably prevent the cutting sheet 4 from sliding, and also to prevent the cutting sheet 4 from sliding when pulled from the baseboard 2. Even if it is peeled off, the synthetic resin film 3 will not peel off from the baseboard 2, and the cutting sheet 4 can be easily removed.
can be attached to and detached from the baseboard 2.

The distribution density of the fine sucker holes that causes the difference in adhesive strength as described above can be easily achieved by the coating density of the coating agent, the number of fine sucker holes contained in the coating agent, or a combination of these. In other words, the coating density of the coating agent can be adjusted by simply changing the silk screen original plate, and the fine suction holes contained in the coating agent can be adjusted by diluting the coating agent to the desired concentration with a solvent. The adhesive force can be easily selected depending on the material and surface condition of the canting sheet.

In the fixing film of the present invention, the material to be processed, such as a canting sheet, is fixed to the baseboard by the adsorption action of the fine suction holes contained in the coating agent, so there is no transfer of the coating agent even if it is peeled off, and it can be repeated. Even with attachment and detachment, there is almost no decrease in adsorption power.

Furthermore, even if the tip of the cutting ben were to pierce the canting sheet depending on the processing method, since the synthetic resin film is interposed, it will not reach the baseboard and damage the baseboard.

In this example, the adhesive was applied to the synthetic resin film in a dot shape, but if it could be applied uniformly to the film surface, the adhesive would be applied as shown in Figures 4(a), (b), and (c). As shown in the figure, the adhesive 8 is applied to the synthetic resin film 3 in a grid pattern
It may be applied in a), striped form (b), random form (C), or the entire surface.

Furthermore, in this example, we have explained how to fix a cutting sheet (which is made up of two layers and is relatively thick), but when using it for fixing thin paper, etc. When the adhesive is regularly applied, an intermittent tensile force is applied to the paper during the gaps in which the paper is peeled, and the paper may be creased in a direction perpendicular to the peeling direction. However, this problem can be easily solved by applying the coating agent 8 in a random manner as shown in FIG. 4(C).

Furthermore, if a coating agent is applied to the same position on both the front and back sides of a synthetic resin film, the film may become partially thick, resulting in unevenness on the work surface. Such cases are particularly likely to occur when gluing thin paper, and in order to make smooth drawings, it is desirable to apply the adhesive to different positions on the front and back sides to make the thickness of the film uniform. .

〔Effect of the invention〕

Adjustment of the adhesive applied to both sides of the synthetic resin film interposed between the workpiece material and the baseboard of the processing equipment as a sheet for fixing the workpiece material according to the present invention can control the application density of the adhesive. This can be easily done, for example, by using a silk screen printing method, or by selecting the concentration of the coating agent to increase or decrease the amount of fine suction holes contained in the coating agent. Therefore, it is possible to impart adhesive strength to the synthetic resin film that corresponds to the material and surface condition of the baseboard or workpiece material.

Therefore, it is applicable not only to sheet bodies but also to three-dimensional workpiece materials.

In addition, since the adhesive strength is due to the suction effect of the fine suction cup holes, there is no transfer of the adhesive even when peeled off, and it can be used repeatedly, making it more economical than magnetic nods or electrostatic adsorption methods. Excellent in sex.

Furthermore, as mentioned above, even if the tip of the cutting ben were to pierce the cutting sheet, the presence of the synthetic resin film would prevent damage to the baseboard.
