Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a device for cutting materials into predetermined dimensions, and is particularly capable of cutting relatively short and thin materials such as disposable chopsticks at a predetermined cutting angle. The present invention relates to a material cutting device.

[Prior art]

Traditionally, decorative cases with excellent designs have been made by assembling thin square materials such as disposable chopsticks into parallel grid shapes, stacking them vertically, and slightly shifting the position of the corners of each parallel grid in the circumferential direction. It is known that it can be done.

By the way, when making such a decorative case using, for example, disposable chopsticks, it is necessary to cut the disposable chopsticks to a certain size in advance, and the cut surface is not only a flat surface perpendicular to the axis, but also an oblique surface. It is preferable that it can be cut into a cut or a chevron cut.

However, in the past, there was no suitable material cutting equipment, so the method was to measure the length using a tape measure, mark the specified position, and then cut using a knife, etc. However, this method was not easy to perform and was difficult to measure. There is a drawback that the length of each material varies due to errors. In particular, when cutting the ends of materials diagonally or in a chevron shape, it is almost impossible to make the lengths and end shapes of each material the same.

[Purpose of invention]

The present invention was devised in view of the current situation, and provides a material cutting device that can accurately and easily cut relatively thin materials to a set length, and can also accurately perform diagonal cuts and chevron cuts. The purpose is to

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an example of a material cutting device according to the present invention, and FIG. 2 is a similar plan view, and in both figures, reference numeral 1 denotes a rectangular plate-shaped pedestal. At one end in the longitudinal direction of the upper surface of the pedestal 1, a pair of rising pieces 2, 2 facing each other at a required interval in the width direction are erected, and one end of the cutter arm 3 is fitted between the two rising pieces 2, 2. , is attached via a male-threaded support shaft 4 so as to be able to swing vertically.

This cutter arm 3 is a rectangular bar-shaped arm body that can swing up and down as shown in Figures 1 to 3.
3a, a rectangular concave notch 5 is provided on one end of the arm body 3a on the support shaft 4 side, and a presser plate 3b is fitted into the concave notch 5.
The blade 7 is detachably held via a screw 6 that fastens the arm body 3a and the presser plate 3b. The blade 7 is formed of a slightly thick single-edged safety razor blade, and can be moved, reversed, and replaced by detachment by loosening the screw 6. Further, as shown in FIGS. 1 and 3, cutouts 8 are provided in the arm body 3a and the presser plate 3b at positions directly below the screws 6, which are cut in an arcuate shape upward from the lower end surface. Consideration is given so that the arm main body 3a and the presser plate 3b do not get in the way during cutting.

In addition, a first
As shown in the figure and FIG. 2, a rod-shaped material guide member 9 is arranged perpendicular to the extending direction of the blade 7.
This material guide member 9 is rotatable in the horizontal direction using a screw 10 screwed from the lower surface side of the pedestal 1 as a fulcrum, and
By tightening the screw 10, it is temporarily fixed at a required rotational position.

The upper surface of the material guide member 9 is formed with a material placement portion 9a having a scale 11 marked according to the distance from the blade 7 as shown in Figs. 1 and 2, and a guide portion 9b which is integrally formed at one end of the material guide member 9 in the width direction and rises in a stepped shape from the material placement portion 9a.
The vertical surface formed between the first and second guide portions 9b and 9c serves as a guide surface 9c for the material.
As shown in the figure, the scale 1 on the material placement portion 9a
A number of screw holes 12 are provided in accordance with the stopper 1, and set screws 4 for fixing the position of a stopper 13 are screwed into the screw holes 12.

As shown in FIGS. 1 and 2, this stopper 13 has an L-shaped plate shape that can be slid along the stepped portion on the upper surface of the material guide member 9, and the stopper 13 has a
4 passes through an elongated hole 15 provided in the stopper 13 and is screwed into the screw hole 12, so that the stopper 13 can be finely adjusted within the range of this elongated hole 15.

In addition, in the center of the end surface of the material guiding member 9 on the guide portion 9b side, there is provided a circular arc surface located on the base 1 and having an outer edge centered at the position of the screw 10, as shown in FIGS. 1 and 2. A moving angle confirmation plate 16 is integrally provided, and between the outer edge of the rotation angle confirmation plate 16 forming an arcuate surface and the top surface of the pedestal 1, it is possible to visually read the intersecting angle of the material guide member 9 with respect to the blade 7. Possible scale 1
7 is provided.

In the above configuration, when cutting a material, the screw 10 is first tightened so that the material guiding member 9 can be rotated about the screw 10 position as a fulcrum. Then, the rotation position of the material guide member 9 is determined while visually reading the scale 17, and then the material guide member 9 is fixed in position by tightening the screw 10.

Next, remove the set screw 14, loosely insert the set screw 14 into the screw hole 12 at an appropriate dimension position, finely adjust the stopper 13 within the range of the elongated hole 15, and then tighten the set screw 14 to fix the stopper 13. do.

Next, the material is placed on the material guide member 9, and the end surface of the material is brought into contact with the stopper 13 while the side surface is in contact with the guide surface 9c. At this time, the stopper 13 is fixed in position according to the scale 11, and the scale 11 is attached according to the distance from the blade 7, so simply by bringing the end surface of the material into contact with the stopper 13, the cutting length can be adjusted. Uniquely determined.
Therefore, the cutter arm 3 is swung from the solid line position to the chain line position as shown in FIG. This results in
The material is cut by the blade 7.

If the required number of materials are cut and the blade 7 at the notch 8 position is damaged, the position of the blade 7 is moved or reversed to position the unused portion of the blade 7 in the notch 8. Thereby, the entire length of the blade 7 can be used evenly. If the blade 7 is damaged over its entire length, replace it with a new one.

Therefore, by simply placing the material on the material guide member 9 and cutting it, it is possible to cut the material to a specified size extremely easily. Further, since the material guide member 9 can arbitrarily adjust its intersecting angle with respect to the blade 7, it is possible to easily cut not only at right angles but also at an angle. It's easy. Furthermore, by cutting the material multiple times while rotating the material in the diagonal cut state at a required rotation angle around the axis, it is possible to cut not only flat surfaces but also chevron-shaped cuts, conical cuts, etc.

Further, since the blade 7 for cutting the material is a single-edged safety razor blade, an extremely good cutting surface can be obtained and it is also easily available. Further, by moving the position of the blade 7 in the extending direction or reversing it, the cutting location of the blade 7 can be adjusted, thereby making it possible to use the entire blade 7 evenly to extend its life. In addition, most of the blade 7 is held between the arm body 3a and the presser plate 3b from both sides, and only the notch 8 is exposed, so that the blade 7 is securely supported and extremely safe.

Also, the stopper 13 is connected to the screw hole 1 of the set screw 14.
The fixing position can be changed by changing the attachment position to 2, and fine adjustment can be made using the elongated hole 15, so the required material length can be easily obtained.

FIG. 4 shows another embodiment of the present invention, in which the material guide member 9 can be temporarily fixed at a required rotation position from the upper surface side of the pedestal 1, and the rotation range of the material guide member 9 is The aim is to expand the

That is, as shown in FIG. 4, the rotation angle confirmation plate 16 integral with the material guide member 9 is provided with an arcuate elongated hole 18 centered at the screw 10 position, and this arcuate elongated hole 18 has a tip end. A butterfly bolt 19 that is screwed into the pedestal 1 passes through it. And the material guide member 9 is
By loosening the butterfly bolt 19, it rotates in the horizontal direction about the screw 10 position, and by tightening the butterfly bolt 19, it is temporarily fixed at a desired rotational position. Further, as shown in FIG. 4, a cut face 20 is provided at the corner of the rising piece 2 which supports the cutter arm 3 so as to be able to swing up and down via the support shaft 4, as shown in FIG. As a result, the rotation range of the material guide member 9 is expanded.

However, by configuring the lever, it is possible to fix the material guide member 9 at a required rotation position from the top side, and while visually checking the scale 17, the material guide member 9 can be moved to the required rotation position. Can be easily fixed. Furthermore, the cutting surface 20 provided on the rising piece 2 expands the rotation range of the material guide member 9, making it possible to cut materials in a greater variety of ways.

Although not particularly explained in the above embodiments,
The screw members that need to be operated when using the screws 6, 10 and the set screw 14 may all be screw members that can be operated by hand, such as butterfly bolts, thereby eliminating the need for tools such as a screwdriver and further improving operability. I can do it.
