Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is intended to cut a wide range of industrial wastes, whether soft or hard, into industrial wastes such as industrial supplies, old materials, household furniture and other household items, and to cut them into small pieces. Also, the present invention relates to an industrial waste cutting apparatus and a cutting method thereof capable of extremely efficiently performing a cutting operation of a soft material.

[0002]

[Prior art]

 In recent years, industrial waste has become a very wide variety, and there are industrial goods, old materials, household goods such as old furniture, etc., and these are being disposed of in large quantities. In order to dispose of these industrial wastes efficiently, it is necessary to cut them into several small parts. Various types of cutting equipment have been developed to cut industrial waste into fine pieces, but most of them cut relatively hard waste. For example, plate materials for construction can be said to be stable in shape and easy to cut. In addition, cutting of synthetic resin products such as plastics can be relatively easily performed. Particularly, even with a hard material to be cut, the cutting operation can be performed very efficiently by improving the strength of the cutting blade.

[0003]

[Problems to be solved by the invention]

 As described above, the cutting of relatively hard waste such as synthetic resin such as plastic material or metal material can be easily performed because the shape is stable. However, some industrial waste is composed of soft materials. For example, hoses, industrial sheets, industrial nets, tires, etc. are made of vinyl, rubber, glass wool, asbestos, and the like. As described above, the material to be cut can be roughly classified into a hard and thick material, a hard and thin material, a soft and thick material, and a soft and thin material. The hard and thick material described above can be said to be most easily cut as described above.

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

[0005] It can be said that objects belonging to the above and are difficult to cut. This is because a soft object (or a thin object even if it is hard) is easily deformed into the same shape as the outer shape of the cutting blade during the cutting operation, and is easily clung to the cutting blade. Therefore, industrial wastes made of soft materials are extremely difficult to cut. During the cutting of such soft material waste, uncut soft material adheres or becomes entangled with the cutting blade of the cutting device one after another, and the cut 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 the cutting ability of the soft material waste is reduced by being attached to or entangled with the cutting blade in the cutting operation of the waste material.

[0006]

[Means for Solving the Problems]

 Therefore, the inventor of the present invention has conducted intensive studies to solve the above-mentioned problems. As a result, the present inventor has determined that the present invention includes a fixed jaw having a penetrating portion, a mountain-shaped blade portion penetrating into the penetrating portion, An industrial waste cutting machine comprising a movable cutting body that is swingable with respect to a fixed jaw, and a part of the cut material cut by the penetration of the mountain-shaped blade portion can be stuck to the penetrating portion. The equipment is used to cut waste into small pieces, regardless of whether it is soft or hard, so that the waste can be easily disposed.Especially, the cutting work of soft materials can be performed very efficiently. It is a solution to the problem.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the present invention mainly includes a fixed jaw A, a movable cutting body B, and a drive unit casing C, as shown in FIGS. The fixed jaw A is connected to the drive unit housing C, and the movable cut body B is pivotally supported by the drive unit housing C so as to swing freely, and the movable cut body B opens and closes on the fixed jaw A. It has a flexible structure. The power source for the swinging operation of the movable cutting body B is a hydraulic cylinder 12 mounted in the drive housing C, and the tip of the piston rod 12b of the hydraulic cylinder 12 is connected to the movable cutting body B. [See FIG. 1 (B)].

The industrial waste cutting device is mounted on the tip of a boom 22 of a construction vehicle such as a hydraulic shovel and operated. Here, industrial waste refers not only to waste generated from manufacturing sites such as factories or construction sites, but also to large-sized waste such as electrical appliances and furniture from general households and general offices. included. Examples include wall paper, plumbing hoses, insulation, carpets, nets, wires, tires, tatami, tinplate, and glass wool.

First, the fixed jaw A mainly includes a jaw 1 and a penetrating portion 2. The shape of the jaw 1 is formed such that the cross-sectional area gradually becomes smaller and narrower as it goes from the connection side with the drive unit housing C to the tip. The surface of the jaw 1 that faces the movable cutting body B, that is, the surface that cuts the workpiece W together with the movable cutting body B is referred to as a cutting work surface 1a (see FIG. 3A).

Next, the penetrating portion 2 is formed in a long hole or a slot shape along the longitudinal direction of the jaw 1, and more specifically, a substantially rectangular shape extending in the longitudinal direction of the jaw 1. When the movable cutting body B described later is in a closed state, the mountain-shaped blade 6 penetrates. The inner surfaces on both sides in the width direction of the penetrating portion 2 are referred to as inner wall surfaces 2a, 2a as shown in FIG. The inner wall surfaces 2a, 2a are parallel surfaces, and the chevron blade 6 enters between the inner wall surfaces 2a, 2a (see FIG. 4A).

There is an embodiment in which resistance surfaces 2a ₁ , 2a ₁ are formed on both inner wall surfaces 2a, 2a, respectively. The resistance surfaces 2a ₁ , 2a ₁ are formed so that when a material to be cut W, W,..., Which will be described later, is packed in the penetrating portion 2, the resistance is increased so that the material to be cut W can easily stay in the penetrating portion 2. The purpose is to prevent the material to be cut W from falling off from the penetrating portion 2 easily. The resistance surfaces 2a ₁ , 2a ₁ may have a cross-sectional shape formed of a large number of continuous triangular mountain shapes (see FIG. 16A) or may have a saw-tooth shape [FIG. (B)). Or, the inner walls surfaces 2a, 2a plate pieces is fixed to also present embodiment to the resistor surface 2a ₁ a cross-sectional shape of the inner wall surface 2a as uneven [see FIG. 16 (C)].

Cutting support members 3 are formed on the cutting work surface 1 a and on both sides in the width direction of the penetrating portion 2. The cutting support members 3 have a length substantially equal to the length of the penetrating portion 2 along the longitudinal direction of the penetrating portion 2. The cutting support members 3, 3 bite into the workpiece W when the cutting operation is performed by closing the fixed jaw A and the movable cutting body B, and the workpiece W shifts or moves unexpectedly. This makes it difficult to make cutting. The center of each of the cutting support members 3, 3 is recessed in a flat, substantially arcuate shape along the longitudinal direction. The opposing surfaces of the cutting support members 3, 3 are the inner wall surfaces 2a, 2a.

Further, a fixed tip blade 4 is formed at the tip of the jaw 1. The fixed tip blade 4 is a plate-like material mounted substantially orthogonally to the longitudinal direction of the jaw 1, and its center in the width direction is cut into a substantially V-shape toward the movable cutting body B side. A notched groove 4a is formed (see FIG. 3A). The vicinity of the top of the fixed tip blade 4 is sharply pointed [see FIGS. 1 (A) and 3 (A)]. The fixed tip blade 4 prevents the workpiece W from spilling from between the fixed jaw A and the movable cut body B when performing the cutting operation with the fixed jaw A and the movable cut body B. It is.

Next, as shown in FIG. 1, FIG. 2, and FIG. 3B, the movable cutting body B includes a cutting body 5, a mountain-shaped blade 6, an auxiliary blade 7, a swing frame 8, and the like. It is composed of The cutting body 5 may be formed as a reinforcing portion by forming a flat groove-shaped recess in the thickness direction, or a reinforcing material such as a rib may be formed as necessary. The cutting main body 5 is formed integrally and continuously with a mountain-shaped blade 6 and an auxiliary blade 7, thereby constituting a part that plays a role of cutting. The outer peripheral portion of the cutting main body 5 is surrounded by the frame main body 8 a of the swing frame 8. The oscillating frame 8 is formed extremely rigidly so as to sufficiently withstand the cutting operation, and the oscillating base 8b formed on the oscillating frame 8 is pivotally connected to the drive unit casing C. . The pivot支箇plant called pivot portion S ₁ [FIG. 1 (A), (B) refer to Fig.

The swing frame 8 is formed with a cylinder connecting portion 8c. The cylinder connecting portion 8c is pivotally connected to the hydraulic cylinder 12, and the movable cutting body is driven by using the hydraulic cylinder 12 as a drive source. B is rocked. The connection portion between the cylinder connecting portion 8c and the hydraulic Cylinders 12 referred to as pivot portion S _2. Further, a tip claw 8d is formed at a free tip of the swinging frame 8, and the workpiece W falls off between the fixed jaw A and the movable cutting body B during the cutting operation by the tip claw 8d. To prevent

As shown in FIGS. 17 (A) and 17 (B), an auxiliary cutter 13 is attached to a pivotal support portion S ₁ between the fixed jaw A and the movable cutting body B, and a rigid member such as a reinforcing bar is provided. The material can be cut. The auxiliary cutter 13 includes a fixed cutter portion 13a formed on the fixed jaw A side and a swing cutter portion 13b formed on the movable cut body B side, and is fixed by swinging the movable cut body B. The cutter section 13a and the swinging cutter section 13b intersect to cut a reinforcing bar, a steel frame and the like.

Next, as shown in FIGS. 1A and 2A, the mountain-shaped blade portion 6 is formed so as to protrude toward the fixed jaw A side, and as described above. As described above. The blade edge 6t of the mountain-shaped blade portion 6 is formed so that the thickness gradually decreases toward the blade edge, and the shape of the blade edge 6t, that is, the shape of the tip portion, is a cross section orthogonal to the blade extending direction. It is formed so as to have a substantially semicircular shape.

The double-edged crest 6t ₁ constituting the both surfaces in the thickness direction of the blade edge 6t locations, 6t ₁ is formed to have the same inclination angle, the angle of both facets 6t _1, 6t ₁ θ ranges from about 20 degrees to about 40 degrees. More specifically, the cutting edge angle θ is preferably 30 degrees. When the fixed jaw A and the movable cutting body B are closed, the mountain-shaped blade portion 6 penetrates into the penetrating portion 2, and the vicinity of the outer end in the blade crossing direction is a notch groove of the fixed tip blade 4. 4a.

The mountain-shaped blade 6 has a plurality of types in shape, and the first type is an arc-shaped mountain-shaped blade 6a having an arc shape. Specifically, it is formed in a flattened arc shape so that the central portion thereof is swelled most along the blade extending direction (longitudinal direction of the blade) (see FIGS. 1A and 3B). This type of mountain-shaped blade portion 6 has an arc shape along the blade length direction, so that there is no corner along the blade length direction, and the shear force is uniform at any point in the blade length direction. .

Next, as shown in FIGS. 17A and 17B, the second type of the shape of the mountain-shaped blade portion 6 is a polygonal mountain-shaped blade portion 6b formed in a substantially half-moon polygonal shape. . The polygonal mountain-shaped blade portion 6b is formed by a plurality of continuous linear blade tips having different inclinations. Mountain shape blade portion of the type 6 is to straight cutting edge 6b _1, 6b ₁ adjacent to continuous at an appropriate angle. In the illustrated embodiment, four straight cutting edges 6b ₁ , 6b ₁ ,... Are formed continuously, and there are three corners between each adjacent straight cutting edges 6b ₁ , 6b ₁ . The polygonal chevron shaped blade unit 6b, a plurality of linear cutting edge 6b _1, 6b _1, ... and, by arrangement of a plurality of corner portions which they form a row Umono cutting of workpiece W.

Next, the third type of the mountain-shaped blade portion 6 is a triangular mountain-shaped blade portion 6c formed in a substantially triangular shape as shown in FIGS. 18A and 18B. It is. The Mikadoyama shaped blade portion 6c is Ri Contact become blade edge 6t is the most sharp at the apex angle 6c ₁ place, the blade edge 6t of the apex angle 6c ₁ place, chevron-shaped blade portion of the other two types 6 is easier to cut into the workpiece W.

Here, the relationship between the size of the mountain-shaped blade portion 6 and the size of the through portion 2 will be described. It is enough to penetrate with some margin. Specifically, assuming that the thickness of the chevron blade 6 is 60 mm, the inner dimension in the width direction of the penetrating portion 2 is approximately 70 mm. The relationship between the dimensions is determined based on the thickness of the mountain-shaped blade portion 6. If the thickness of the mountain-shaped blade portion 6 changes, the inner dimension of the through portion 2 in the width direction also increases. It changes appropriately.

Here, the operation of the mountain-shaped blade portion 6 penetrating into the penetrating portion 2 is such that the blade edge 6t of the mountain-shaped blade portion 6 enters the penetrating portion 2 halfway in the depth direction. Are cut into the workpieces W, W,... Adhered in a clogged state (see FIG. 1B and the like). However, depending on the type and situation of the industrial waste to be handled, the structure may be such that the blade edge 6t of the mountain-shaped blade portion 6 reaches the vicinity of the opening on the outside of the fixed jaw A of the penetrating portion 2.

The cutting main body 5 is formed with an auxiliary blade 7 at a position adjacent to the mountain-shaped blade 6 and near the swing center side of the movable cutting body B together with the mountain-shaped blade 6. I have. The auxiliary blade portion 7 has a straight blade edge along the cutting direction and does not penetrate the movable cutting body B, but is provided at a position other than the penetrating portion 2 on the cutting work surface 1a. The protruding workpiece W is cut.

Next, the drive unit housing C includes a housing unit 9 and a connecting unit 10. A hydraulic cylinder 12 is mounted in the housing 9. The connecting portion 10 serves to be attached to the tip of a construction vehicle boom 22 such as a hydraulic shovel. The swing operation of the movable cutting body B with respect to the fixed jaw A is performed by the hydraulic cylinder 12. Specifically, it is pivotally connected at the cylinder portion 12a TogaYura dynamic freely pivot portion S ₁ of the hydraulic cylinder 12 to the drive unit housing C. Further, the Pisutonro head 12b of the cylinder connecting portion 8c formed on the swing frame 8 of the movable cutting member B is the hydraulic cylinder 12 is pivotally connected at pivot portion S _2, the cylinder portion 1 of the hydraulic cylinder 12 When the piston rod 12b protrudes from 2a, the movable cutting body B swings with respect to the fixed jaw A (see FIGS. 1A and 1B).

Next, a method for cutting the workpiece W by the industrial waste cutting apparatus of the present invention will be described with reference to FIGS. First, an industrial waste cutting device is installed at the end of the boom of construction vehicles such as hydraulic excavators. The swing operation of the movable cutting body B with respect to the fixed jaw A can be operated by an operator from the construction vehicle. First, a description will be given of an operation for cutting a soft and thick industrial waste material W made of a material such as a sheet material, a hose, a net, a glass wool mat, and a rubber material.

First, the workpiece W is sandwiched between the fixed jaw A and the movable cutting body B, and the movable cutting body B is swung to close toward the fixed jaw A side. First, the material to be cut W is packed into the penetrating portion 2 without being cut so as to be entangled with the chevron blade 6, and the material to be cut W adheres to the inner wall surfaces 2a, 2a of the penetrating portion 2. (See FIGS. 5 and 6). At this time, when the resistance surfaces 2a ₁ , 2a ₁ are formed on both the inner wall surfaces 2a, 2a, the workpiece W can be firmly adhered to both the resistance surfaces 2a ₁ , 2a ₁ .

Further, the next cut material W (the cut material W different from the cut material W already packed in the penetrating portion 2) is sandwiched between the fixed jaw A and the movable cut body B, and the movable cut is performed. The body B is rocked, closed toward the fixed jaw A, and the next cut material W is packed into the penetrating portion 2 in which the front cut material W is packed. In this way, the next cut material W is packed and adhered to the through portion 2 together with the front cut material W (see FIG. 7). Further, the next cut material W is packed into the penetrating portion 2, and this is repeated several times, so that the inside of the penetrating portion 2 is eventually filled with the packed cut material W, W,. It will be full (see Figure 8).

The workpiece W in the through portion 2, W, ... are in a state of clogged full, sandwiched between the fixed jaw A and the movable cutting member B a workpiece W _n A New, the movable cutting member B Closed to the fixed jaw A side, when the material W to be cut is to be cut by the mountain-shaped blade 6 with the shearing force F, the material W, W,. A force R is generated (see FIGS. 9 and 10). Further, when the mountain-shaped blade portion 6 enters the penetrating portion 2, the reaction force R increases with respect to the shearing force F, and the workpieces W, W,. about to be cut) a new acts friction between the workpiece W _n, tensile force T acts on a new workpiece W _n. Thereby, chevron-shaped blade portion 6 blade edge 6t of may shearing force F is concentrated against a New workpiece W _n, to compress the workpiece W _n A New, cutting (FIG. 11 , See FIG. 12). The reaction force from the workpieces W, W,... Clogged in the penetrating portion 2 with respect to the shearing force F of the mountain-shaped blade portion 6 is distributed load r, r, around the blade edge 6t. , The reaction force R is illustrated assuming that these distributed loads r, r,... Are concentrated on the cutting edge 6t.

[0031] Then, in the cutting operation described above, each time to cut the workpiece W _n A New, workpiece W present in the state clogging in the through portion 2, W, ... are chevron-shaped blade portion 6 of the By the pressing by the shearing force F, the liquid is gradually discharged from the penetrating portion 2 to the outside of the fixed jaw A. Therefore, even if the cutting operation is continued, the clogging of the workpieces W, W,... In the penetrating portion 2 does not increase by a certain amount or more, and the workpieces W, W,. The state is maintained.

As shown in FIGS. 14A and 14B, the penetrating portion 2 is gradually widened toward the lower part of the fixed jaw A, so that the clogged state of the penetrating portion 2 is increased. The cutting materials W, W,... Can be easily discharged, and the shearing force F by the mountain-shaped blade portion 6 can be slightly reduced. Further, as shown in FIGS. 15A and 15B, the width of the cut material W, W,... It is also possible to suppress the discharge, increase the reaction force R against the shearing force F by the mountain-shaped blade 6, and thereby slightly increase the shearing force F.

The material W, W,... To be cut into the penetrating portion 2 is condensed too much and condensed and hardened, and the mountain-shaped blade portion 6 cannot penetrate into the penetrating portion 2. it is to prevent the cutting of the cutting material W _n becomes impossible. As described above, the amount of the workpieces W, W,... That are clogged in the penetrating portion 2 is always kept constant because the penetrating portion 2 is moved from the cutting work surface 1a of the fixed jaw A to the fixed jaw. This is because the shape was penetrated toward the outside of A.

FIG. 13 shows an outline of a cutting structure using the mountain-shaped blade portion 6 and the workpieces W, W,. That is, this drawing discloses that the workpieces W, W,..., Which are clogged in the penetrating portion 2, serve as a cutting base in the cutting operation of the mountain-shaped blade portion 6. but a work for diagram describing the stress state and each part at the time of shearing the workpiece W _n a new Yamagata shaped blade portion 6.

[0035] In FIG. 13 (A), the by a New workpiece W _n chevron shaped blade portion 6, when a cut so, workpiece W in the state clogging in the through portion 2, W, ... to narrowing eat some extent, FIG. 13 at (B), the stress generated in each part reaches the blade edge 6 t chevron shaped blade portion 6 is cut over intensively compressive stress in the workpiece W _n a new Is the thing.

Although the cutting operation has been described for the case where the material to be cut W is soft and thick, the cutting process is substantially the same for the case where the material to be cut W is soft and thin. That is, as shown in FIG. 15 (B), the shearing force F of the mountain-shaped blade portion 6 is concentrated on the blade edge 6t, and the workpieces W, W clogged in the blade edge 6t and the penetrating portion 2. , ... by the compression stress caused by the reaction force R between, it is intended to cut the a new workpiece W _n to be cut.

Next, when the material to be cut W is manufactured from a metal material, a synthetic resin, a hard rubber, or the like, and is, for example, a plate material, furniture, a home appliance, or a fold, the material to be cut W is compared with the material to be cut. Since it has a stable shape that is hard and not easily deformed, it can be cut in a stable state without entanglement with the mountain-shaped blade 6 in the cutting work. You can go.

[0038]
