Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material cutting apparatus which is used as a printer or a ticket vending machine as a seed and which can be arbitrarily selected from perforation processing or full width cutting.

[0002]

2. Description of the Related Art In recent years, along with the multifunctionalization of various printers and ticket vending machines, the sheet material cutting device mounted on these machines is also required to be multifunctional. It has become necessary to equip a piece of paper with a multifunctional cutting device capable of both perforating and full-width cutting. In order to meet this requirement, Jitsuko Sho 54-45276 (Act Kai 52-1625)
No. 90) gazette uses a type of cutter commonly known as a guillotine type, and the movable blade of this cutter is provided with a saw-toothed blade edge, and perforation processing or full-width cutting is performed by controlling the stroke of the movable blade. There is disclosed a cutting device for arbitrarily performing. In addition, actual public Sho 59-3840 (actual development Sho 58-59594)
In the publication, a rotary cutter is used, and a rotary blade is provided with a continuous blade edge for full width cutting and an intermittent blade edge for perforation processing, and one of the blade edges is pressed against a fixed blade. Then, a cutting device which performs perforation processing or full width cutting is disclosed.

[0003]

Conventionally, there has been no cutting device capable of performing perforation processing or full-width cutting arbitrarily with one cutter. Therefore, especially for paper which is a sheet material to be handled by a ticket vending machine, a perforation machine is previously used. The eyes had to be processed and the work such as printing and winding had to be performed. In this case, the process for perforation processing is indispensable, and the sheet material must be handled carefully. Therefore, in order to solve the above problems, a guillotine-type cutting device having a saw blade-like movable blade disclosed in Japanese Utility Model Publication No. 54-45276 was developed as described above.
However, the guillotine-type cutting device is generally tall because the thin plate-shaped movable blade operates in a direction substantially perpendicular to the pass line of the sheet material, and thus the space for the cutting device becomes large. There is. For this reason, it has been attempted to install two rotary cutters for perforation processing and full-width cutting side by side, and to perform the intended processing or cutting with either of the two, but with this method, Extra space is required in the direction parallel to the sheet material pass line.

Therefore, as one apparatus for solving the above-mentioned problems, Japanese Utility Model Publication No. 59-3840 discloses a rotary type perforating machine and a cutting machine capable of performing full width cutting. However, in this device, since the movable blade is provided with the cutting edges for perforation processing and full-width cutting, it is necessary to release the pressure contact with the fixed blade on one of the unnecessary movable blades. There is a problem that the cost becomes high. An object of the present invention is to solve the above problems and to provide a rotary type sheet material cutting device which occupies a small space, is small and lightweight, and can perform perforation processing and full-width cutting by one unit.

[0005]

The inventor of the present application has conducted a study to solve the above-mentioned various problems, and as a result, has found that the position substantially symmetrical with respect to the axis of one movable blade that rotates or swings. It is found that a fixed blade can be press-contacted to each of these two cutting edges by providing a cutting edge on the one cutting edge, one fixed blade is formed with a saw blade for perforation processing, and the other fixed blade is formed on the fixed blade. The present invention has been completed by forming a straight blade for full-width cutting, and pressing an arbitrary fixed blade against a movable blade so that perforation processing and full-width cutting can be freely selected. That is, as a schematic structure, a fixed blade is pressed against the rotary blade from the left and right with respect to one rotary blade, and perforation processing and full-width cutting can be arbitrarily selected. Specifically, the invention of the present application is such that both ends thereof are rotatably or swingably supported, and a movable blade having a blade edge at a position substantially symmetrical with respect to an axis of rotation or oscillation, and a blade edge of the movable blade intermittently. It is composed of a saw blade fixed blade having a saw-toothed blade edge in pressure contact and a straight blade having a straight blade edge continuously in pressure contact with a movable blade. The saw blade fixed blade and the straight fixed blade are arranged so as to face each other on the left and right of the axis of rotation or swing of the movable blade.

In this type of cutting device, it is natural that the cutting edges of the movable blade and the fixed blade form a shear angle and a biting angle with each other. To form a shear angle, the blade edge of the movable blade is inclined with respect to the axis of the movable blade itself, the axis of the movable blade is inclined with respect to the blade edge of the fixed blade, and the blade edge of the rotary blade is fixed. Various methods are known, such as a method of tilting the blade and installing the blade. Further, the formation of the biting angle is mainly performed by pressing one end of the fixed blade against a ring provided at one end of the movable blade and causing the other end of the fixed blade to interfere with the movable blade. Various methods are known, such as a method of inclining a wire with respect to the axis of the movable blade to cause interference,
In the present invention, the shear angle and the biting angle may be formed by appropriately selecting the above method.

[0007]

[Function] When the sheet material is passed through the gap formed by the movable blade edge and the two fixed blade edges and perforation processing is required,
The movable blade is rotated or swung in a direction in which the movable blade and the saw blade fixed blade are in pressure contact with each other, and the movable blade and the saw blade fixed blade cooperate to process perforations on the sheet material. Next, when full-width cutting is required, the saw blade fixed blade and the straight fixed blade are arranged at positions facing the axis of the movable blade. Rotate or oscillate to cut the entire width of the sheet material and separate it. In this way, the movable blade is moved to the intended fixed blade side for arbitrary processing or cutting depending on the purpose of perforation processing and full-width cutting.

[0008]

Next, the present invention will be described in detail with reference to examples and the drawings. 1 and 2 show an embodiment of the cutting device according to the present invention. The rotary blade 3 was swingably supported at both ends by bearings on the A side plate 5 and the B side plate 6.
The saw blade fixed blade 1 and the straight blade 2 were pressed against each other by a leaf spring 4 attached to a bottom plate 7 from both sides so as to sandwich the rotary blade 3. By using the leaf spring 4, it is possible to support the two fixed blades and press-contact the movable blade, which is advantageous in terms of cost. The saw blade fixed blade 1 is notched on the blade edge portion to form a saw blade-shaped blade edge.
Machined a straight cutting edge. When the movable blade and the fixed blade of the saw blade move by pressing, the cutting edge of the movable blade meshes with the crest of the fixed blade of the saw blade and cuts, then the cutting edge of the movable blade moves to the valley of the fixed blade of the saw blade and cuts. The contact between the movable blade and the saw blade fixed blade becomes intermittent. In the present embodiment, the above-mentioned shear angle is formed by inclining the cutting edge line of the movable blade with respect to the axis of the movable blade itself as shown in FIG. 1, and the biting angle is provided at one end of the movable blade. One end of the fixed blade was pressed against the ring and the leaf spring was adjusted so that the other end of the fixed blade interfered with the tip of the rotary blade.

Using the sheet material cutting device manufactured in this way, perforation processing and cutting test were performed on paper.
The sheet of paper is passed through a gap formed by the blade edge of the movable blade 3 and the blade edges of the two fixed blades 1 and 2, and the movable blade 3 is swung in the direction of the saw blade fixed blade 1 to move the movable blade 3 When one of the blade edges and the blade edge of the saw blade fixed blade 1 were pressed against each other to form perforations on the paper, normal perforations could be processed without difficulty.
Next, the movable blade 3 is swung in the direction opposite to the perforation to the straight fixed blade 2 side, and the other blade edge of the movable blade 3 and the blade edge of the straight fixed blade 2 are pressed to cut the entire width of the paper. Then, I was able to cut with a normal smooth cut edge. In the sheet material cutting device having such a structure, when the inner side of the rolled curl of the paper is the fixed blade side, the front end of the paper is the second fixed blade in the traveling direction of the paper. It is easy to get caught in the paper, causing paper jams.
Therefore, as shown in FIG. 3, a guide A is provided at an intermediate position between two opposing fixed blades to guide the paper and prevent the occurrence of paper jam. In FIG. 4, the leaf spring is elongated and the tip thereof is bent into an L shape to form a guide B, and it is not necessary to install another member for supporting the guide. In the present embodiment, the fixed blade is supported and pressure-contacted by using a leaf spring, and the leaf spring has a structure in which both movements of supporting the fixed blade and pressure-contacting the movable blade are combined, but shafts are provided at both ends of the fixed blade. It is also possible to have a structure in which it is swingably supported and pressed against by a compression coil spring or a tension coil spring.
