Abstract

(57) [Summary] [Purpose] To be able to reliably cut sheet materials that are thin and have low rigidity. Attach the two blades 6 and 7 to each support member 3 and 4 so that the intersection part (A) of the blade tips is at the cutting position, and
is configured to guide the sheet-like material 20 to the cutting position (A).

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention cuts sheet materials such as synthetic resin films, metal foils, and paper in the width direction while traveling. This relates to a device for cutting.

0002

[Conventional technology]

Generally, sheet materials such as synthetic resin films, metal foils, and paper are cut in the width direction while traveling. For example, as described in Japanese Patent Publication No. 63-20678, A cutter whose cutting edge is gradually tilted away from the film surface in the forward direction. and a spatula that moves with the cutter and supports the film surface from the opposite side of the cutter. and a driving means for moving the cutter and spatula over the entire width of the film. A cutting device consisting of:

0003 This kind of cutting machine consists of one cutter and one spatula that supports the film. When cutting thin films with low rigidity using a cutting device, , even if the film is supported by a spatula and introduced into the cutting position of the cutter, the film will not cut. The cutter is not cut by the cutter because the cutter is only pressed toward the spatula, and the cutter and spatula are If a buildup occurs at the intersection and the film breaks or the cutter is damaged, There was a problem.

0004

[Problem that the idea aims to solve]

The problem with this invention was when cutting a film that was thin and had low rigidity. , even if the film is supported by a spatula and introduced into the cutting position of the cutter, the film will not cut. The cutter is not cut by the cutter because the cutter is only pressed toward the spatula, and the cutter and spatula are This is because the film may break or the cutter may be damaged due to accumulation at the intersection.

[0005] Ru.

[Means to solve the problem]

In order to solve the above problem, the cutting edge opens in a V-shape toward the entry side of the sheet material. Attach the two blades to the support member so that the opening and the intersection of the blade edges are at the cutting position. The supporting member is formed to guide the sheet-like object to the cutting position. It is set as.

【Example】

FIG. 1 is a front view showing one embodiment of the sheet cutting device of the present invention, and FIG. FIG. In the figure, 1 is a seam along the rail formed on the machine base (not shown). It is a running member that moves in a direction perpendicular to the running direction of the tortoise 20. 2 is the running part It is the main support member attached to the material 1, and the upper support member 3 and the lower support member 4 are attached to the bolt 5. It is installed by. The upper support member 3 gradually becomes sheet-like in the traveling direction. A guide surface 3a that is inclined in a direction away from the top surface of the object 20 and a guide surface 3a that is parallel to the surface of the sheet-like object. An inner surface 3b is formed, and an upper cutter 6 is attached by an upper pressing member 8. Further, the lower support member 4 gradually moves away from the lower surface of the sheet-like object 20 in the traveling direction. A guide surface 4a that is inclined in the direction of The lower cutter 7 is attached by a lower pressing member 9. The blades 6 and 7 have cutting edges. You can use double-edged ones, but use single-edged ones, and each knife has blades 6 and 7. It can also be arranged so that the first flat side is in contact with it. The above-mentioned upper blade 6 and lower blade Item 7 has a blade edge opening in a V-shape in the forward direction and is arranged so that there is no gap. The intersection (A) is the cutting position of the sheet-like material. Also, the upper support part material 3 and lower support member 4, the sheet-like material 20 does not come into contact with each guide surface 3b, 4b, and Adjust the interval dimension (H) so that the sheet-like material 20 is guided to the cutting position (A). . The main support member 2 or the upper support The mounting hole in either the member 3 or the lower support member 4 is made into a long hole.

[0007] The guide surface of the sheet-like material 20 formed on each of the above-mentioned supporting members 3 and 4 is formed on each of the pressing members 8, 9 can also be formed.

[0008] The sheet-like material cutting device of the present invention has a cutting mechanism in which the cutting edge is shaped like a V-shape in the direction of travel. Attach the two blades 6 and 7 to each support member 3 and 4 so that they open at the intersection of the blade edges ( A) is in the cutting position, and each support member 3, 4 is placed in the sheet-like material 20. Since the sheet material is shaped to guide it to the cutting position (A), the sheet material moves up and down. The sheet material can be reliably guided to the cutting position without coming into contact with the cutting tool. Wear. Also, the sheet material 20 is cut by the intersection point (A) of the two blades 6 and 7. This makes it possible to reliably cut even thin and non-rigid sheet materials. can be done.

[0009]

[Effect of the idea]

The sheet-shaped material cutting device of the present invention has a blade edge that opens in a V-shape in the direction of travel. Attach the two blades to the support member so that the intersection of the blade edges is at the cutting position, and Since the member is formed to guide the sheet material to the cutting position, the sheet material Even if the sheet-like object moves up and down, it will not come into contact with the blade, and the sheet-like object will be securely in the cutting position. I can guide you. In addition, the cutting part formed at the intersection of two blades Since it is designed to cut sheet-like materials, it is possible to cut thin, non-rigid sheet-like materials. Even objects can be cut reliably.
