Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a technique that is effective when applied to a cutting processing device, for example, a technique that is particularly effective when applied to cutting processing of empty cans. .

[Prior Art] Conventionally, empty cans have been processed in the following manner, for example.

That is, a large number of empty cans collected in one place by a non-combustible material collection vehicle are pressed into several lumps, which are then melted in an electric furnace or the like and recycled into five cans, etc.

[Problems to be Solved by the Invention] However, this method has the following problems.

That is, since empty cans have a hollow cylindrical shape and are light, they are more difficult to handle when collected than ordinary trash. Additionally, in addition to melting the empty can after it has been turned into a lump by pressing, the paint on the surface of the empty can peels off during the pressing and enters the hollow part of the empty can, and during melting, the paint generates gas inside the empty can. This resulted in poor heat circulation, leading to a deterioration in combustion efficiency.

Similar problems arise with other workpieces.

The present invention was made in view of this point, and includes a workpiece,
In particular, it is an object of the present invention to provide a cutting device that can facilitate the handling of empty cans and also facilitate the melting of objects to be treated.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

[Means for Solving the Problems] Representative inventions disclosed in this application will be summarized as follows.

That is, the cutting apparatus of the present invention includes a workpiece deforming means for deforming the workpiece, and a workpiece cutting means for cutting the workpiece deformed by the workpiece deformation means.

[Operation] According to the above means, the workpiece is deformed into a shape that is easy to cut by the workpiece deforming means, and the workpiece thus deformed is cut by the workpiece cutting means. Therefore, the workpiece is cut into small pieces, which makes handling of the workpiece and I8F! ! It is possible to facilitate A.

[Example code] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic vertical sectional view of a first embodiment of a cutting device according to the present invention.

In the figure, 1 represents a frame, and this frame 1
In the upper, middle, and lower tiers, processing object deforming means 2,
A first workpiece cutting means 3 and a second workpiece cutting means 4 are provided. Furthermore, a hopper 5 for charging the workpiece is connected above the workpiece deforming means 2 . Then, in this cutting processing apparatus, the workpiece put into the hopper 5 is first transformed into a shape that is easy to cut by the workpiece transforming means 2, and then the workpiece is transformed by the workpiece transforming means 2. The workpiece is cut by the first workpiece cutting means 3 and further finely cut by the second workpiece cutting means 4.

Incidentally, here, the above-mentioned object deforming means 2. Since the configurations of the first workpiece cutting means 3 and the second workpiece cutting means 4 are approximately the same, only the workpiece deforming means 2 will be described in detail, and the first workpiece cutting means 3 and the second workpiece cutting means 4 will be described in detail. Regarding the configurations of the means 3 and the second workpiece cutting means 4, only the members different from the workpiece deforming means 2 will be explained.
The other members are given the same reference numerals and the explanation thereof will be omitted.

First, the object deforming means 2 will be explained.

The object deforming means 2 is constructed as follows.

That is, the object deforming means 2 includes a pair of rotary cutters 6.7, as shown in FIG. This rotary cutter 6.7 has blades 10.7 mounted on two shafts 8, 9, which are horizontally suspended in parallel to the frame 1, in the circumferential direction.
11 (FIG. 3) (this disk 12 will be explained in detail later) and a collar 13 having a smaller diameter than the disk 12 are alternately fitted and supported. The rotary cutter 6.7 is installed so that the disks 12 and the collars 13 face each other, and a gap of, for example, about 3 ann is formed between the cutting edges of the opposing disks 12.12. It is designed so that

In addition, spur gears 14 and 15 that mesh with each other are attached to one ends of shafts 8 and 9 that project outward from the frame l, so that the shafts 8 and 9 rotate in opposite directions. . On the other hand, Hurray! ,
A motor (rotary drive device) 17 is connected to the other end of the shirt 1 - 8 that protrudes outward from the shirt 1 through a gear mechanism 16 . As this motor 17, for example, one that can selectively rotate the disk 12 in the forward direction (the direction of the arrow in figure ff53) and the reverse direction is used.

The motor 17 also includes a load detection device 18 that detects the load (current value, although not particularly limited) applied to the disk 12, and a load detection device 18 that controls the motor 17 according to a signal from the load detection device 18 to A control device 19 for changing the direction of rotation of the rotor is connected.

In addition, at a position outside the rotary cutter 6.7 in the frame t11, there is a comb-shaped fixed blade 20 in contact with the rotary cutter 6.7.
．． 20 are provided. Further, a cylindrical metal 21 is provided in contact with the bearings of the shafts 8 and 9. Here, the cylindrical metal 21 has a function of supplementing the bearing action of the bearing, and also has a function of preventing dust and the like from adhering to the bearing.

Next, the disk 1 of the cutting processing device configured as described above will be described.
2 will be explained in more detail.

FIG. 3 shows a schematic configuration of the disk 12. As shown in FIG. To explain the outline based on FIG. 3, blades 10 with a small cutting surface 10a and blades 11 with a large cutting surface 11a are alternately arranged on the outer periphery of the disk 12. There is. That is, in the disk 12 of the embodiment, the central angle at which the blades 10°11 stand is changed (θ
1. θ2), therefore, the rear surface 10b of the blade 10
is larger than the rear surface 11b of the blade 11. In addition, in this disk 12, the cutting edge surface is formed so as to be the radial surface of the disk 12, and on the other hand, the rear surface (conveyance surface) is continuous with the cutting edge surface and defines the blade. The cutting surfaces of the blades are converged on the proximal ends of the cutting surfaces of adjacent blades.

The first and second object cutting means 3.4 are constructed as follows.

First, the first workpiece cutting means 3 (FIG. 4) will be explained. As mentioned above, this workpiece cutting means 3 has substantially the same structure as the workpiece deforming means 2 described above. , is different from this processing object deforming means 2 in that the rotary cutter 6.7 is formed so that the thickness of the disk 12 and the thickness of the collar 13 are equal, and the disk 12 and the opposing collar 13 are opposed to each other. The second point is that a gap of, for example, about 1 inch is formed between the cutting edge of the opposing disk 12 and the outer peripheral surface of the collar 13. In this first workpiece cutting means 3, the disk 12 is moved in the direction shown by the arrow in FIG.
．． 12 rotates and cutting is performed in such a manner that the workpiece is drawn between the disks 12.12.

On the other hand, if we explain the second workpiece cutting means 4 (FIG. 5), as described above, this workpiece cutting means 4 has approximately the same structure as the workpiece deforming means 2 described above. The difference from this processing object deforming means 2 is that the one-turn cutter 6.7 is formed so that the height of the disk 12 and the thickness of the collar 13 are equal, and the five-turn cutter 6.7 is formed so that the height of the disk 12 and the thickness of the collar 13 are equal. The collars 13 of the discs 12 and 13 are placed in opposing positions, the cutting edge of the opposing disc 12 is in contact with the outer circumferential surface of the collar 13, and the mounting direction of the discs is reversed. The object to be processed is cut between the cutter 6.7 and a comb-like fixed blade 21.21 disposed outside the cutter 6.7.

Next, the operation of the cutting device configured as described above will be explained.

When an empty can, for example, is put into the hopper 5 as an object to be processed, the empty can is drawn between the disks 12.12 by the disk 12.12 of the object transforming means 2, and the empty can is crushed by the disk 12.12. transformed into a state.

In this case, as mentioned above, the cutting surface 10 of the blade 10.11
a, 11. Since the sizes of a are different, empty cans of different sizes can be easily drawn between the disks. That is, according to this processing object deforming means 2.

The empty can is cut into the motor 1 by the cutting surface 10a of the blade 10.
Large empty cans or deformed empty cans that cannot be pulled in by the rear surface 10a of the blade 10 because they are floating are pulled in by the other blade 11.
is easily drawn into the disc 12.12 by the cutting surface 11a.

Next, the deformed empty can is sent to the first processing object cutting device 3 at the next stage. Then, it is cut to a certain size. In this first workpiece cutting device 3 as well, the cutting surface 10 of the blade 10.11 is
Since the sizes of a and lla are different, deformed empty cans of different sizes are easily drawn between the disks and cut.

Next, the empty cans cut in this way are sent to the second processing object cutting device 4 in the lower stage. And here,
It is further cut into smaller pieces. In this second workpiece cutting device 4 as well, the sizes of the cutting surfaces 10a and lla of the blades 10.11 are made to be different as described above, so deformed empty cans of large and small sizes can easily be placed between the disks. It is pulled in and cut off.

Further, during such processing, the level of the drive current of the motor 17 is detected by the load detection device 18. Then, when the level of this drive current exceeds a predetermined level (for example, the rated current level) (for example, when an empty can becomes clogged), a control signal is issued from the control device 19, and the motor 17 is turned in the reverse direction. be rotated. As a result, the clogged empty can is temporarily pushed back upwards. As a result, the blockage is cleared, the current level of the motor 17 drops below a predetermined level, and the control device! The motor 17 is rotated in the forward direction by the signal from i19, and the empty can is deformed and cut again. In this case, although there is no particular restriction, if the - motor 17 is stopped and reversed, all the motors 17 disposed above it are stopped and reversed.

According to the cutting apparatus of the embodiment configured as described above, the following effects can be obtained.

That is, since the empty cans are cut after being deformed by the object deforming means 2, the empty cans can be easily cut into pieces, making it easier to handle and melt the empty cans after cutting. .

In addition, the level of the drive current of the motor 17 is constantly detected,
Since the rotation direction of the motor 17 is changed according to this detection result, it is possible to prevent empty cans from clogging in advance or to quickly relieve the clogging after the fact, thereby reducing the load on the motor 17. Empty cans can be efficiently deformed and cut without being overspent.

Furthermore, since this embodiment uses a disk 12 having two types of blades 10 and 11 of different sizes in the circumferential direction, it is possible to efficiently handle large and small or deformed empty cans without placing any load on the motor or shaft. It can be easily deformed and cut without applying any stress.

In addition, the second workpiece cutting means 4 includes a rotary cutter 6.
Since the empty can is cut between the blade 7 and the fixed blade 20, the empty can is cut into smaller pieces than when cutting only with a pair of rotating power vines.
Its handling and melting becomes easier.

Although the invention made by the present inventor has been specifically explained above based on Examples, it goes without saying that the present invention is not limited to the above Examples and can be modified in various ways without departing from the gist thereof. Nor. For example, a claw may also be provided around the collar 13 to prevent empty cans from clogging. Further, a press machine may be used as the processing object deforming means 2. Further, a disk having blades with a uniform cutting surface size may be used, or a disk having three or more types of blades with different cutting surfaces may be used.

Furthermore, depending on the case, either the first or second object cutting means may be omitted.

In the above explanation, the invention made by the present inventor was mainly applied to the processing of empty cans, which is the background of the invention, but it is not limited thereto.For example, it can also be used for processing empty bottles or plastics, etc. .

[Effects of the Invention] The effects obtained by typical inventions disclosed in this application are briefly explained below.

That is, since the object to be processed is once deformed and then cut, the object to be processed can be easily cut into pieces, making handling, melting, etc. of the object to be processed easier.

Incidentally, the cutting device of the present invention can be easily installed in the city or on non-combustible material collection vehicles.
