Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device, and more particularly to a rubber-like elastic rubber product such as waste belt or waste rubber, or a paper product such as newsprint, printing paper, gravure paper, art paper, or a lumber product. Various products such as wood such as wood and plywood, resin products such as synthetic resin, control panels, slate, other building materials, and resin products such as synthetic resin.The shape is a thick plate or a circular or polygonal cross section. The present invention relates to a cutting device for cutting materials having various shapes such as a rotatable shape such as a roll shape and the like.

[0002]

2. Description of the Related Art For example, as an example of a rubber product among the above-mentioned various materials, a conveyor belt used in an iron mill has a thickness of 180 mm and a width of 2 m, and this conveyor belt is a consumable product. There is a need to finely cut or crush the rubber-like elastic material of the conveyor belt, which is a waste material, whether it is buried, incinerated or recycled. Since the rubber-like elastic body is extremely difficult to cut unlike other materials, it is presently difficult to cut a rubber-like elastic body having a large thickness and a large shape as described above.

[0003] Conventionally, it is conventionally possible to cut a particularly thick and large rubber-like elastic material using a known cutting device, for example, a cutting device such as a grinder, a chain saw, or a shearing device that shears with a hundred-ton press. Attempts have been made, but no cutting device has been found that can cut efficiently.

[0004]

For example, when a thick rubber plate is cut with a conventional chainsaw, the rubber melts due to frictional heat generated by the chainsaw blade, and is welded between the chainsaw blades to clog the blades. As a result, there is a problem in that the sharpness of the chainsaw deteriorates and cutting cannot be performed efficiently.

Further, even when a grinder is used, there is another problem that the cutting cannot be performed efficiently.

When a rubber plate is cut by press shearing of hundreds of tons, the thickness that can be cut varies depending on the magnitude of the load of the press. Has a limitation, and it is difficult to cut even a rubber plate having a thickness of about 80 mm.

Further, there is a problem that such a large press shearing as described above is expensive.

[0008] The above problems with rubber products are as follows.
The same problem applies to other materials.For example, even in a resin product such as a synthetic resin, a resin, particularly a thermoplastic resin, is also used due to frictional heat generated by a cutting blade such as a chain saw and a grinder. There was a problem of melting. Also, paper products have a problem that the sharpness is poor and the product is burnt by the frictional heat, so that the value of the product is reduced or the product is defective.

Further, in the conventional cutting apparatus, a thick and large-sized rubber-like elastic body is not easy to handle.
In addition, it is difficult to successfully cope with objects having different shapes such as a so-called thick plate having a shape such as a flat plate or a corrugated plate, and a shape having a rotatable cross-sectional shape such as a thick cylinder. There was a point. For example, in shearing, it is impossible to cut an object having a rotatable cross-sectional shape such as a thick cylindrical shape, and after cutting a thick plate-shaped object into a strip, This operation is not easy because it is necessary to turn the band-shaped object to be turned 90 degrees and then feed it into the shearing in the longitudinal direction to cut it finely.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to particularly easily and efficiently cut a thick-shaped object to be cut, and further to form a thick plate or a thick cylindrical object.

It has a disk shape of m, has a shaft hole 71 at the center thereof, which is mounted on the cutter rotating shaft of the cutting device, and has a total of 36 blades provided at equal angular intervals around the entire circumference. In FIG. 6, when the cutter 60 is mounted on the cutting device, the direction of rotation of the cutter 60 is counterclockwise, and each blade has a tip at the front end in the direction of rotation of the cutter 60 (hereinafter simply referred to as “rotation direction”). 72 (the cutting edge) is fixed by brazing. 36
Of the total number of blades, nine predetermined numbers are set as one blade group, and the total number of 36 blades is divided into four blade groups. Of the nine blades in this one blade group, the blade located at the head in the rotation direction is defined as a reference (hereinafter, this reference blade is referred to as a “reference blade”), and the reference blade 61 is a cutter as shown in FIG. It is located on the width center line L.

The second blade 62, which is located behind the reference blade 61 in the rotational direction, is bent rightward with respect to the center line L of the cutter width from the base of the blade. One side edge 62a (hereinafter, referred to as “outside edge of the blade edge”) located on the outer side from the cutter width center line L among the side edges of the blade tip 72 in the width direction is the right side of the cutter width center line L in the rotation direction. Located in. In the present specification, as described above, bending from the base of the blade to the left or right with respect to the cutter width center line L in the rotation direction is referred to as “set bending”, and the set bending angle is referred to as “set angle”. The bent blade is called a "set blade".

[0066] Thus, 62 will be referred to as "first right clams blade" blade outer edges 62a of the first right clam blade 62 is positioned at a distance S ₁ on the right side from the cutter width center line L. The distance S ₁ is about 2 mm.

The third blade 63 is a “first left set blade”.
Thus, the blade is bent from the base of the blade to the left with respect to the cutter width center line L, and the outer edge 63a of the blade tip is located on the right side of the cutter width center line L in the rotation direction. Blade outer edge 63a is located at a distance S ₁ on the left side from the cutter width center line L. That is, from the cutter width center line L, the first
It is the same size as the distance of the cutting edge outer edge 62a of the right set blade 62.

The second right set blade 64 is bent more to the right than the first right set blade 62, and the outer edge 6 of the second right set blade 64 is cut.
4a is a cutting edge outer edge 62a of the first right set blade 62 described above.
It located from positions to the right, at a distance of S ₂ from the cutter width center line L on the right. That distance S ₂ is the distance S ₁ is greater than value.

The fifth blade 65 is an "escape blade" and is located on the cutter width center line L similarly to the reference blade 61. This blade is located between the escape blade 65 described later, and is provided with a so-called blade play. It is not always necessary to provide a blade of this kind, but after cutting with the blade in the front in the rotation direction, When the rubber-like elastic body, which is an object, is released from the compressive force of the blade at the time of cutting and the cut wall surface of the object to be cut is about to protrude, the cut wall surface is provided with a space to escape and the protruding portion is formed by this escape blade It is considered that this is effective in making the cutting with the following set blade and making it easy to cut with the subsequent set blade. Further, the relief blade 65 is located between the above-mentioned "second right set blade" and the later-described "second left set blade" in the rotation direction, and these two set blades are the outer edge of the blade tip. The distance between the edge and the cutter width center line L has substantially the same size on the left side and the right side, respectively, and there may be a case where the space between the two set blades is large and cannot be cut off. It has the effect as an auxiliary blade in that the part is cut by the escape blade 65.

The sixth blade 66 is a “second left set blade”.
The left edge of the second left set blade 66 is bent more greatly than the first left set blade 63, and the outer edge 6 of the second left set blade 66 is bent.
6a is a cutting edge outer edge 63a of the first left setting blade 63;

It located from positions to the right, at a distance of S ₃ from the cutter width center line L on the right. That distance S ₃ is the distance S ₂ is greater than numbers.

The eighth blade 68 is a “relief blade” and is located on the cutter width center line L, similarly to the reference blade 61. This is located between a third left set blade 69 described later, and its operation is the same as that of the above-described escape blade 65.

The ninth blade 69 is a “third left set blade”
The left edge of the third set blade 69 is bent more than the second left set blade 66 to the left.
9a is a cutting edge outer edge 66a of the second left setting blade 66
Located from positions to the left, at a distance of S ₃ from the cutter width center line L to the left. That distance S ₃ is the distance S ₂ is greater than numbers.

One blade group has the above configuration, and the other three blade groups have the same configuration.

The cutter 60 of the present invention is not limited, and may be more or at least more than the number of blades in the present embodiment. Further, the number of blade groups for dividing the total number of blades of the cutter 60 into blade groups is not limited to four. Further, the number and arrangement of the set blades and the escape blades constituting each blade group are not necessarily the same, and the number of blades in one blade group is not limited.

In each blade group, each set blade positioned rearward in the rotation direction with respect to the reference blade 61 is a set blade bent alternately left and right of the cutter width center line L in the rotation direction. This is one feature. As each set blade is positioned rearward in the rotational direction with the reference blade 61 at the front, the distance between the outer edge of the blade edge of each set blade and the cutter width center line L gradually increases. It is characterized by being formed as follows. That is, when the blade groups on the entire circumference of the cutter are developed in a plane, each set blade of each blade group has an arrowhead shape as a whole in the rotational direction as shown in FIG. The arrow-shaped blade group is repeatedly formed on the entire circumference of the cutter from the first blade group to the fourth blade group.

In each blade group, all other blades positioned rearward in the rotation direction from the reference blade 61 are not provided with the above-mentioned “escape blades”, and the left side of the cutter width center line L in the rotation direction is not provided. "Left set blade" bent alternately to the right and to the right
And a "right set blade".

As described above, the distance between the outer edge of the cutting edge of each of the two set blades and the center line L of the cutter width is substantially the same on the left and right sides. Forming the "left set blade" and the "right set blade" is desirable in order to achieve a uniform cutting effect on both side edges in the width direction of the cutter 60, and constitutes one excellent feature of the present invention. It is.

As the above-mentioned "escape blade", the distance between the outer edge of the edge of the two set blades and the center line L of the cutter width is substantially the same on the left and right sides, respectively. "And" right set blade "are effective in that, as described above, a portion that is not cut by an object to be cut due to a large interval between the two set blades is cut by a relief blade. .

The cutter 60 of FIG. 6 is mounted on the cutting device,
As a result of cutting the rubber-like elastic body, it was possible to cut very well. A rubber plate having a size of 2m x 2m in a plane is cut with a cutter 60.
2 and FIG. 3, the cutting operation was completed in about 2 minutes. At this time, the cutter 60
Thread-like cuttings were generated from the vicinity of both side edges of the sample, showing excellent cutting properties. Incidentally, when an object to be cut having the same size as the rubber-like elastic body was cut by a conventional grinder, the cutting operation was completed in about two hours.

The cutter 60 has excellent cutting properties as described above. To explain the operation, as shown in FIG.
First, the cut portion A enters the cutter width center line L by the reference blade 61, and the cut portion A is closed by the elastic force of the rubber-like elastic body itself.
To cut off the right wall surface of the cut portion A in the rotation direction. When the cutting force of the first right set blade 62 is applied to the rubber-like elastic body, the cut portion B is formed. However, since the rubber-like elastic body escapes due to its own elasticity, a portion that is not separated from the wall surface occurs.

Next, the first left set blade 63 is cut in such a manner that the left wall surface of the cut portion A is cut off in the rotation direction to form a cut portion C. However, the first
As in the case of the cutting with the right set blade 62, there is a portion that is not separated from the wall surface.

Next, the second right set blade 64 is cut in such a manner as to cut off the right side wall surface of the cut portion B in the rotation direction to form a cut portion D. Some parts are not separated from the wall.

The relief blade 65 is not directly related to the cutting of each wall surface, but performs auxiliary cutting such as an overhanging portion from the cutting wall surface or an uncut portion located on the cutter width center line L as described above. It is.

Next, the second left set blade 66 is cut in such a manner that the left wall surface of the cut portion B is scraped off in the rotation direction to form a cut portion E. Some parts are not separated from the wall.

Thereafter, in the same manner as described above, the third right set blade 6
The cut portion F is formed by scraping off the right wall surface of the cut portion D in the rotation direction by 7 and the left wall surface of the cut portion E is cut by the third left set blade 69 in the rotation direction. A notch G is formed.

Following the cutting by the blade of one blade group, the cutting by the blade of the next blade group is performed, and the same cutting action is sequentially repeated by the blades of the following blade group.

The cut B, the cut D, and the cut F are continuous, while the cut C, the cut E, and the cut G are continuous, and the cut pieces of the cut object are connected. Thread-like chips are produced. Therefore, each blade has a small contact area with the wall surface of the object to be cut, and hence the resistance applied to the blade is small. Therefore, the frictional resistance between the cutter and the object to be cut is small, so that the generated frictional heat is low. As a result, the problem that the object to be cut welds to the blade as in the related art is considered to be solved. In addition, since the cut object becomes a thread-like chip, it is possible to avoid a situation in which fine chips remain between the blades and melt due to frictional heat and adhere to the blades. .

In the above-described embodiment, the rubber-like elastic body is particularly described as the object to be cut W. However, the cutting device of the present invention can be applied to newsprint, printing paper, gravure paper, art paper in addition to rubber products. Paper products such as paper sleeves, wood products such as lumber products and plywood, or resin products such as synthetic resins,
Since it is effective for cutting various products such as control panels, slate, other building materials, and resin products such as synthetic resins, the cut object is not limited to the rubber-like elastic body.

FIG. 11 shows another embodiment of the present invention.
, And the same components as those in the above-described embodiment are denoted by the same reference numerals to simplify the description.

This embodiment is configured by adding the following apparatus to the cutting apparatus of the above-described embodiment.

A handle support member 56 is erected at one end of the guide arm 12 on the worker side, and a cutter support table feed handle 55 is journaled on the upper end of the handle support member 56. On the other hand, a bracket (not shown) protrudes from the lower surface of the movable base 13, and the bracket is provided with a screw portion (not shown, female screw) whose horizontal direction is the horizontal direction. A spindle 48 screwed to the screw portion is supported on the upper surface of the guide arm 12 along the longitudinal direction of the guide arm 12. One end of the guide arm 12 is provided so that the rotation of the cutter support feed handle 55 is transmitted to the axis of the cutter support feed handle 55 by a rotation transmitting means such as a sprocket, a chain, or a gear.

Therefore, when the operator rotates the cutter support base feed handle 55 in the clockwise direction toward the cutter side, the rotation of the cutter support base feed handle 55 is transmitted through rotation transmission means (not shown), and the spindle is rotated. When the spindle 48 meshes with a screw portion (not shown), the movable table 13 moves forward in the Y direction as viewed from the operator, while rotating the cutter support table feed handle 55 in the counterclockwise direction. By doing so, the movable base 13 moves rearward in the Y direction as viewed from the operator.

Reference numeral 57 denotes an operation panel, more specifically, the rotation / stop of the cutter and the roller 2 of the roller rotation driving means.
The operation panel 7a is rotated and stopped, and is fixed at substantially the eye level via an operation panel support member 58 erected on the cutter support base 16. The entire operation panel 57 is an operation panel support member 58. The upper part is provided so as to be freely rotatable in the horizontal direction. The operator grips the handle 49, rotates the operation panel 57 to a desired position where it can be easily operated, and fixes the operation panel 57 by the operation panel fixing means 59.

Can be cut. On the other hand, with respect to an object to be cut whose cross section can be rotated, such as a thick cylinder, by rotating the object mounting table of the thick plate, the cross section of the thick cylinder or the like is rotated. The object to be cut is easily opened on the worktable having a rotatable shape, and then the work with a rotatable cross section such as a thick cylinder is placed on the worktable. The object to be cut can be mounted and rotated by the object mounting table to be cut finely by the cutting means. Therefore, it is possible to easily and efficiently cut a workpiece having different shapes such as a thick flat workpiece and a thick cylindrical workpiece capable of rotating in cross section.

As the cutting means, a movable table is movably disposed, an arm is pivotally supported on the movable table so as to be able to move up and down, a cutter is mounted on the arm, and the cutter is driven by a motor. Therefore, by turning the cutter rotated by the motor up and down, the thick plate-shaped object can be easily and efficiently cut into a rectangular shape, and the cross-sectional shape of a thick cylindrical shape having a different size can be rotated. An object to be cut having a movable shape can be easily and efficiently cut into small pieces in the axial direction.

Further, a guide arm is provided above the moving table of the cutting means. A movable table is provided movably on the guide arm, and the arm is provided on this movable table so as to be able to move up and down. Therefore, by fixing the movable table at a desired position and moving the movable table along the guide arm, a thick plate-shaped workpiece can be easily cut with a cutter,
In addition, the cutter can be easily brought close to the outer peripheral surface of an object to be cut whose cross-sectional shape is rotatable, such as a thick cylinder of a different size. The object to be cut, which rotates on the object mounting table having a rotatable cross-sectional shape such as a shape, can be easily cut inward from the outer peripheral surface.

In the present invention, the cutting means includes:

Because the cutting means can be stopped by grasping together, even if an emergency occurs during the cutting work,
The cutting means can be immediately stopped, and safety can be improved.

Further, the cutter is formed in a disk shape, and the blade formed on the entire circumference of the cutter is divided into a plurality of blade groups formed by a plurality of blades. Since the set angle of each blade has an arrowhead shape as a whole in the direction of rotation as a whole, the cutting position of each blade constituting each blade group is particularly different with respect to an object to be cut of a rubber-like elastic body. There is an effect that the cut wall surface is cut so as to be scraped off by a subsequent blade, and as a result, it can be cut efficiently and easily. Therefore, the cutter is an effective cutter for an object to be cut of a rubber-like elastic body, and is also an effective cutter for an object to be cut of another material such as a resin product, a paper product, and wood.
