Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is widely used in the sewing industry, for example, Gerber Garment (USA)
CAM (Computer Aided Manu)
The present invention relates to a film for enhancing the vacuum suction force of an automatic cutting machine such as a factory.

[0002]

2. Description of the Related Art In an automatic cutting machine using CAM manufactured by Gerber Garment Co., a stack to be cut is first placed on the bed of the apparatus, a vinyl sheet is placed on the stack, and vacuum suction is performed vertically downward. , The stack is fixed to the bed and the knife is moved or the bed is moved to cut.

When the stack is fixed to the bed by this vacuum suction, the bed is made of upright bristles, and the bed is divided into a plurality of pieces due to the mechanism of the apparatus. The power spreads,
There was a problem of misalignment during cutting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and its purpose is to uniformly and effectively downward in the vertical direction without diffusing the vacuum suction force. To act on.

[0005]

That is, the present invention relates to a film for enhancing the vacuum suction force of an automatic cutting machine. More specifically, the present invention relates to a film in which a pressure-sensitive adhesive is applied parallel to the winding direction of a long film. The present invention relates to a film for enhancing vacuum suction force of an automatic cutting machine, characterized by being processed on only one side and one side of a film so as to have a width of 1/3 to 1/4 of the width of the film.

[0006]

In the above structure, a PET (polyethylene terephthalate) film is a typical example of the long film constituting the present invention because of its excellent mechanical properties and low cost. The thickness of the film is sufficient if it is strong enough to withstand vacuum suction. If the strength is too high, the knife for cutting may be scratched. Therefore, the film thickness is preferably 50 to 100 μm, more preferably about 75 μm. Things are good.

Next, the adhesive constituting the present invention is used so that the film of the present invention is used between the beds of an automatic cutting machine, and the film does not slip or drop from the bed when the bed rotates. The purpose of this is not to require peeling strength, and a general pressure-sensitive adhesive can be sufficiently used. Further, in order to process such an adhesive into a film, a treatment such as coating or coating can be exemplified.

Further, the processing width of the pressure-sensitive adhesive is set to 1 of the film width.
The reason for limiting it to / 3 to 1/4 is that if the entire surface of the film is processed with an adhesive during cutting, the adhesive adheres to the knife to make it less sharp and the adhesive cuts from the knife to the cut product. Because it is transcribed. That is, by limiting the width of the adhesive to 1/3 to 1/4 of the width of the film, the adhesive of the film of the present invention and the knife do not come into direct contact with each other.
Further, the film of the present invention is preferably a roll in which the adhesive is protected by release paper, but since it does not require peeling strength so much, it is a long film in which the adhesive is not protected by the release paper. It may be a roll that is directly wound like a cellophane tape.

The structure and application of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing the configuration of the present invention. That is, the present invention comprises a film 1, a pressure sensitive adhesive 2 and a release liner 3. When used in an automatic cutting machine, the release liner 3 is peeled off to use the film 1 and the pressure sensitive adhesive 2.

FIG. 2 is a partially cutaway perspective view in which a part of the automatic cutting machine manufactured by Gerber Garment Co. is omitted, and the bed 4 is arranged in a vertical direction so that it can be rotated like a belt conveyor. The bed is of a split type, and each bed is composed of upright bristles 7.
The holes 5 are present on the entire surface of the support at the bottom of the bed 4, and a suction force acts vertically downward by vacuum suction. A vacuum chamber 6 exists below the bed 4.

FIG. 3 is a partially cutaway perspective view of the film 8 of the present invention when it is stuck between the beds in a direction perpendicular to the longitudinal direction. That is, in this application example, the film 1 is
It is a PET film having a width of 50 mm, a length of 2 m and a thickness of 75 μm. The PET film is coated with the adhesive 2 having a width of 15 mm on one side and only one side. First, the film 8 of the present invention is cut into a length of 2 m. Next, the release paper 3 is peeled off and the adhesive 2 is attached between all the beds so that the adhesive 2 is on the lower side, so that the film 8 of the present invention acts as a partition between the beds. Therefore, the suction force does not diffuse between the beds made of the upright bristles 7 and effectively acts downward in the vertical direction, so that the stack to be cut can be firmly fixed.

In this application example, the vacuum suction force is better than that in the conventional method, and the stack body to be cut is placed on the bed 4, and a vinyl sheet is further covered on the bed body to perform the vacuum suction, whereby the stack body is collected. Was firmly fixed to the bed 4, and even if it was cut with a knife while keeping this state, there was no problem such as displacement.

[0013]

As described above, the present invention relates to a film for enhancing the vacuum suction force of an automatic cutting machine. By using the film of the present invention in an automatic cutting machine, a vacuum for cutting is obtained. The suction force can be effectively acted downward in the vertical direction without diffusing, and a problem such as positional deviation of cutting does not occur. Further, since the film of the present invention is in a roll shape, it is possible to easily obtain a film having a required length by cutting it into an appropriate size.
