Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extremely wide variety of industrial goods, old materials, whether soft or hard,
Industrial waste cutting device that cuts finely into industrial waste such as household furniture such as old furniture so that it is extremely difficult to cut soft materials, which is extremely difficult, and its cutting Regarding the method.

[0002]

2. Description of the Related Art In recent years, industrial waste has come into a very wide range of types, and there are industrial goods, old materials, daily necessities such as old furniture, etc., and these are being discarded in large quantities.
In order to dispose of these industrial wastes efficiently, it is necessary to cut them into several fine parts. Various types of cutting devices have been developed to cut industrial waste into small pieces, but most of them are for cutting relatively hard waste. For example, it can be said that a plate material for construction has a stable shape and is easily cut. Further, it is possible to relatively easily cut a synthetic resin product such as plastic. Even with a particularly hard material to be cut, the cutting work can be performed extremely efficiently by improving the strength of the cutting blade.

[0003]

As described above, the cutting of the synthetic resin such as the plastic material and the relatively hard waste such as the metal material should be performed because the shape is stable. Can be done easily. However, many industrial wastes are composed of soft materials. For example, it is made of vinyl, rubber material, glass wool, asbestos, etc., and includes hoses, industrial sheets, industrial nets, tires and the like. As described above, the materials to be cut are roughly classified into hard and thick materials, hard and thin materials, soft and thick materials, and soft and thin materials. It can be said that the hard and thick material described above is the easiest to cut as described above.

The hard and thick materials include thick plates, wall boards, furniture and the like. The hard and thin material is manufactured from a thin plate metal material, and there are lockers, cabinets, and the like. These are made of a thin plate metal material and are not cut during the cutting work, but only bent so as to have substantially the same outer shape as the cutting blade.
The soft and thick material is a heat insulating material such as a rubber plate and a glass wool material, and the soft and thin material is a net, a sheet and the like.

It can be said that the above items 1 and 2 are difficult to cut. This is because a soft object (or a hard object, but a thin object) is likely to be deformed into a shape substantially the same as the outer shape of the cutting blade during the cutting work, and is likely to cling to the cutting blade. Therefore, the industrial waste made of soft material is
It is a very difficult material to cut. Then, while the waste of such soft material is being cut, the uncut soft material adheres or entangles with the cutting blade of the cutting device one after another, and this cutting material eventually covers the cutting blade. In the worst case, the cutting operation may not be able to continue. An object of the present invention is to prevent a situation in which cutting ability is deteriorated due to sticking or entanglement with a cutting blade in the cutting operation of waste material made of such a soft material.

[0006]

Therefore, as a result of earnest studies to solve the above problems, the inventor has found that the present invention provides a movable cutting body having a straight blade and a movable cutting body. A fixed jaw having a groove portion through which the linear blade portion penetrates, and a blade receiving member that is mounted in the groove portion and that abuts on a blade edge of the linear blade portion that penetrates the groove portion. With the industrial waste cutting device and the cutting method, the product cuts finely into pieces so as to make it easier to dispose of the waste regardless of whether it is soft or hard. The above problems have been solved by making the work extremely efficient.

When the movable cutting body B moves, the fixed cutter portion 13a and the movable cutter portion The portion 13b intersects with each other and cuts a reinforcing bar, a steel frame, or the like.

Next, the linear blade portion 6 is formed as shown in FIGS.
As shown in (A) and the like, it is formed so as to project toward the fixed jaw A side, and is a portion that penetrates into the groove portion 2 as described above. The blade edge 6t of the linear blade portion 6 is formed so that the thickness gradually decreases toward the blade edge, but the shape of the blade edge 6t, that is, the tip end portion, is a cross-sectional shape orthogonal to the blade crossing direction. Is formed to have a substantially semicircular shape.

The two cutting edge surfaces 6t ₁ and 6t ₁ forming both surfaces in the thickness direction of the cutting edge 6t are shown in FIGS. 4 (A) and 4 (B).
As shown in FIG. 7, the blades are formed so as to have the same inclination angle, and the angle θ formed by the two cutting edge surfaces 6t ₁ and 6t ₁ is set to about 20 degrees to about 40 degrees. More specifically, the edge angle θ is preferably 30 degrees. Further, in a state where the fixed jaw A and the movable cutting body B are closed, the linear blade portion 6 has the groove portion 2
And the vicinity of the outer end in the blade crossing direction penetrates into the notch groove 4a of the fixed tip blade 4.

The linear blade portion 6 has a plurality of types of shapes, and the first type is the horizontal linear blade portion 6a. Specifically, the blade edge 6t is formed in a straight line along the blade crossing direction (longitudinal direction of the blade) [Fig.
(A), FIG. 3 (B), etc.]. When this type of linear blade portion 6 penetrates the groove portion 2, the linear blade portion 6 is accommodated in a substantially horizontal shape with respect to the opening portion of the groove portion 2.

Next, the second type of the linear blade portion 6 is, as shown in FIGS. 11 (A) and 11 (B), gradually moved from the tip of the movable cutting body B toward the swing center side. The blade is formed so as to have a high height, which is referred to as an outward linear blade portion 6b. The outward linear blade portion 6b penetrates the groove portion 2 from the side of the fixed jaw A and the movable cutting body B closer to the pivotal support portion S ₁ , and particularly when the material W to be cut is concentrated on the pivotal support portion S _1. It is effective for cutting.

The third type of linear blade portion 6 is shown in FIG.
As shown in FIGS. 2 (A) and 2 (B), it is formed such that the blade height gradually decreases from the tip of the movable cutting body B toward the swing center side. Blade part 6c

Since the cutting edge 6t is gradually lowered toward the pivotal support S ₁ , the material W to be cut is less likely to drop from the fixed jaw A and the movable cutting body B when the material W is cut.

Here, the relationship between the dimensions of the linear blade portion 6 and the groove portion 2 will be described. Regarding the inner dimension in the width direction of the groove portion 2, the thickest portion of the linear blade portion 6 has an appropriate margin. It has such a degree that it can be penetrated. To show specific dimensions, for example, the plate thickness of the linear blade portion 6 is about 60
Assuming mm, the inner dimension in the width direction of the groove 2 is about 70 mm. This dimensional relationship is determined on the basis of the thickness of the linear blade portion 6, and if the thickness of the linear blade portion 6 changes, the inner dimension of the groove portion 2 in the width direction can be properly adjusted. It changes.

Here, regarding the operation of the linear blade portion 6 penetrating into the groove portion 2, the blade edge 6t of the linear blade portion 6 enters so as to reach the middle of the groove portion 2 in the depth direction, and the groove portion 2 It comes into contact with or bites into the blade receiving member 3 mounted therein (see FIG. 1B, etc.).

It is mounted and fixed by means such as press fitting. Further, it is preferable that the blade receiving material 3 has voids in an appropriate ratio. This porosity indicates the ease of compression when an external load such as pressure is applied to the material. As a result, when the blade receiving member 3 has an appropriate porosity when performing the cutting operation, when the linear blade portion 6 penetrates the blade receiving member 3 in the groove portion 2 to some extent, The increase rate of the reaction force R becomes large. The porosity is usually preferably about 3% to 30%.

Such materials include paper, plastic sheets and cloth. The blade receiving material 3 having such a property is flexibly deformed with respect to the biting of the linear blade portion 6, and is not further deformed where the linear blade portion 6 is press-fitted to some extent. (See FIG. 10) Since the shearing force F from the linear blade portion 6 is received and the material W to be cut is cut, the cutting work can be performed extremely efficiently.

In particular, it is preferable that the blade receiving material 3 specifically has a large friction coefficient. Further, by using a sheet-shaped member, various shapes can be formed, which is suitable for mounting by being packed in the groove 2.
Further, the blade receiving material 3 is designed so as not to easily fall off in the state of being attached inside the groove portion 2. Such materials include rubber, synthetic resin materials such as vinyl, cloth, paper, wood and the like.

Next, a method for cutting industrial waste (material to be cut) by the industrial waste cutting device of the present invention will be described with reference to FIG. First, the industrial waste cutting device is attached to the tip of the boom 22 of a construction vehicle such as a hydraulic excavator. The swinging operation of the movable cutting body B with respect to the fixed jaw A can be operated by a worker from a construction vehicle. First, the case of cutting a soft and thick industrial waste (material to be cut) made of a material such as a sheet material, a hose, a net, a glass wool mat, and a rubber material will be described.

First, the material W to be cut is sandwiched between the fixed jaw A and the movable cutting body B, the movable cutting body B is swung, and closed toward the fixed jaw A side (FIG. 6 (A)). reference〕.
The material W to be cut receives the reaction force R from the blade receiving material 3 on the blade receiving material 3 in the groove portion 2 by the linear blade portion 6, and the material W to be cut is cut. . Specifically, when the linear blade portion 6 enters the groove portion 2, the blade receiving material 3 in the groove portion 2
The reaction force R also increases with respect to the shearing force F, and friction acts between the blade receiving material 3 in the groove 2 and the material W to be cut (to be cut). The tensile force acts on.

As a result, the edge 6t of the linear blade 6 is
The shearing force F is concentrated on the material W to be cut,
Can be compressed and cut [Fig. 6 (B), (C)]
reference〕. The reaction force from the material W to be cut on the blade receiving member 3 of the groove portion 2 with respect to the shearing force F of the linear blade portion 6 acts as a distributed load r, r, ... Around the blade edge 6t. However, the reaction force R is shown as if these distributed loads r, r, ... Concentrate on the cutting edge 6t.

The material W to be cut is cut by the linear blade portion 6 and the blade receiving member 3 so that the linear blade portion 6 bites into the blade receiving material 3 to some extent, and the stress generated at each portion causes the linear blade portion 6 to move. The cutting edge 6t is applied with a compressive stress intensively on the new material W to be cut. Regarding the cutting action, the material W to be cut is described as being soft and thick.
Even if the material W to be cut is soft and thin, the cutting process is almost the same. That is, the shearing force F of the linear blade portion 6 is concentrated on the cutting edge 6t, and the material to be cut is compressed by the compressive stress due to the reaction force R between the cutting edge 6t and the blade receiving member 3 of the groove 2. It cuts W.

Next, the material W to be cut is a metal material, a synthetic resin,
Manufactured from hard rubber, for example, plate material,

The blade receiving material 3 is attached to the. The blade receiving material 3 receives the blade edge 6t so as to come into contact with the blade edge 6t of the linear blade portion 6. With such a structure, the material W to be cut is sandwiched between the fixed jaw A and the movable cutting body B, and the movable cutting body B is operated so as to be closed in the direction of the fixed jaw A. When cutting the material W to be cut, when the linear blade portion 6 reaches the blade receiving material 3, the linear blade portion 6 contacts the blade receiving material 3 so that There is no uncut portion, and reliable and complete cutting is possible.

This cutting structure is extremely suitable for cutting the material W to be cut, which is particularly soft and elastic and has an appropriate thickness. That is, when the material W to be cut is soft and elastic and has an appropriate thickness, the material W to be cut is normally used.
When the linear blade portion 6 digs into a certain depth, friction is generated between the two and the linear blade portion 6 is dragged by the movement of the linear blade portion 6, and the periphery of the cutting point of the workpiece W also moves with the linear blade portion 6. As a result, a connection part remains in a part of the cut part, resulting in poor cutting.

However, according to the present invention, even when the cutting operation of the linear blade portion 6 is moved so that the cutting point of the workpiece W is dragged, the blade receiving material 3 is straightened at the final stage of cutting. Since the blade edge 6t of the shaped blade portion 6 is received so as to be in contact with the edge portion 6t, there is no place to escape at the cutting portion of the material W to be cut, and reliable cutting can be performed.

As described above, even if the material W to be cut is a soft material and is difficult to cut, the blade receiving material 3 mounted in the groove portion 2 receives the linear blade portion 6 when cutting. It serves as a base, and the work of cutting the material W to be cut can be favorably performed. If the material W to be cut is made of a hard material, its shape is stable, and therefore the linear blade portion 6
It can be cut by ordinary cutting.
As described above, according to the present invention, it can be applied to the cutting of almost any kind of industrial waste, and good workability can be exhibited. Furthermore, since the blade edge 6t is linear along the blade crossing direction, the shape of the linear blade portion 6 is extremely simple, and the blade edge has durability.
There is also an advantage that maintenance and management of the cutting edge can be made extremely easy.

According to a second aspect of the invention, in the first aspect, the cutting work surface 1a of the fixed jaw A and the portion corresponding to the position of the linear blade portion 6 of the movable cutting body B are formed to be substantially flat. By using the industrial waste cutting device as described above, the groove portion 2 is formed in the flat surface 1a ₁ thereof, and the blade receiving material 3 is attached to the groove portion 2, so that the groove portion 2 and the blade receiving material 3 etc. Also has a shape almost equal to the shape of the cutting edge of the linear blade portion 6, and the contact between the blade receiving member 3 and the linear blade portion 6 is uniform at any position. A uniform cutting force can be applied at any position along the direction, and the cutting efficiency of the workpiece W can be further improved.

According to a third aspect of the present invention, in the first or second aspect, the blade receiving member 3 is an industrial waste cutting device formed of a material having elasticity. When the blade edge of the blade portion 6 comes into contact with the pressed state, the blade edge 6t of the linear blade portion 6 can slightly bite into the blade receiving material 3 side. This ensures reliable cutting, and also protects the cutting edge of the linear blade portion 6 during cutting work. Also,
There is also an advantage that the blade edge of the linear blade portion 6 can be protected when it is not used.

According to a fourth aspect of the present invention, in the first, second or third aspect, the blade receiving member 3 is an industrial waste cutting device which is detachably fixed to the groove portion 2. Since the material 3 is detachably fixed to the groove portion 2, when the blade receiving material 3 is damaged or worn due to long-term cutting work, the blade receiving material 3
Can be easily replaced with a new one. Further, by making the blade receiving material 3 detachable, if the blade receiving material 3 is turned over and used after one side thereof is used, the blade receiving material 3 can be used for a longer period of time.

According to a fifth aspect of the present invention, in the first, second, third, or fourth aspect, the cross-sectional shape of the blade edge 6t of the linear blade portion 6 is such that the width-direction both blade edges 6t ₁ , 6t ₁ have the same inclination angle. A sharp cutting edge is formed, and the surface of the blade receiving member 3 is formed to be substantially equal to the shape of the cutting edge of the linear blade portion 6 along the longitudinal direction. Not only W, but also the hard material W to be cut can be efficiently cut.

The invention of claim 6 is based on claims 1, 2, 3, 4
In 5 or 5, the movable cutting body B and the fixed jaw A are provided with the auxiliary cutters 13 in the vicinity of the pivotal support portions thereof, so that the industrial waste cutting device is provided. You can cut anything. For example, it is possible to cut a relatively hard workpiece W such as a reinforcing bar or a small steel frame.
