[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting line device for cutting old tires into small pieces for convenience of transportation.

[0002]

[Prior Art]

 Today, the treatment of used tires has become a major environmental problem, and its use as fuel is expected as one of the countermeasures for this treatment. The cost is slightly lower than that of heavy oil or coal, and the combustion efficiency is never bad, but it is not possible to use a large tire in its original shape, and it is not necessary to transport or store the tire as it is. Since it is difficult to cut, it must be cut into small pieces. If it becomes finer, it will be possible to handle it like transportation and storage of coal, and it will be convenient to use the above-mentioned spent tire as fuel. A "cutting machine for rubber tires and other solid materials" according to Japanese Utility Model Laid-Open No. 57-101022 is a typical example of the prior art.

By the way, a large tire can be finely cut by using the above cutting machine. However, a large number of blades radially arranged and attached to the lower surface of the blade base are pressed against the tire. There is. The pressing of the blade is performed by the operation of the hydraulic cylinder, and its cutting ability is very large. However, since the cutting machine cuts the tire as it is in this cutting machine, the size of the cutting piece becomes large, and if the blade descends during cutting, the tire is deformed into strain and the cutting piece is cut. Shape collapses and its variation expands. Even if the cut pieces used as fuel are as uniform as possible, they not only make handling convenient but also affect combustion efficiency.

Further, if it becomes a tire for a large vehicle such as a truck, it is not easy to carry it into the cutting machine, and an upper main body provided with a hydraulic cylinder and a blade base having a blade fixed thereto are attached to the hydraulic cylinder. It is difficult to fit a large tire into the lower housing of the middle body, and it requires a very large capacity to cut such a large tire, resulting in a large device body.

[0005]

[Problems to be solved by the present invention]

 As described above, the conventional old tire cutting device has the above problems. The problems to be solved by the present invention are these problems.Easy to carry in and out of the device, the tire cut pieces are finer and more uniform, and the device body is relatively compact, so that the work can be performed. A cutting line device that can be easily performed is provided.

[0006]

[Means for Solving the Problems]

 The old tire cutting line device of the present invention is roughly divided into a cutting device, a wheel-slicing device, a loading device, and an unloading device. The basic structure of the cutting device is similar to that of the conventional device.A blade is attached to the lower surface of the blade base to press the tire at the time of cutting and to extract the cut tire cutting pieces from the blade. A stripper is installed, and the blade base moves up and down in conjunction with the hydraulic cylinder. Further, in the present invention, the tire housing portion is provided below the blade base, the base of the housing portion is extended to the left and right (front and rear) thereof, and the chain conveyor running along the base is arranged. The chain conveyor attaches the feeding member, and the feeding member slides on the base, and the feeding member feeds the tire piece placed on the loading side base to the accommodating unit base, where the tire piece is cut by the blade. Then, the cut pieces are sent again by the sending member and fall from the carrying-out side base to the carrying-out device. This carry-out device is also a kind of conveyor.

On the other hand, the wheel-slicing device is a device that cuts into two parts by making a notch on the outer circumference of the tire, and a disk-shaped cutter is provided at the main shaft end, and a support roller that supports the tire is attached to the outer circumference of the support roller. A groove is formed at a position where the cutter meshes with the shaft, and a shaft for mounting the supporting roller is provided so as to be able to move up and down. Then, anti-slip rollers having an uneven outer periphery are provided on both sides of the cutter, and guide rollers are arranged near the cutter on the left and right sides of the cutter as a center. Further, the carry-in device is installed between the wheel-slicing device and the cutting device, but the specific means is not limited. For example, it has a table that moves up and down and a loading arm, and while the table is kept horizontal (substantially horizontal) by the parallel link machine groove, it rises to the height of the loading base of the cutting device, and the loading arm is slidably attached. The tire pieces that have been lifted on the table are pulled into the loading base. Any means may be used for driving the table ascending / descending movement and the loading arm slide. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0014]

[Effect of the device]

 Since the cutting line device of the present invention has a wheel-slicing device and cuts the tire in a state of wheel-slicing, the cutting can be performed without distortion even if the blade bites during cutting. Therefore, the size of the cut pieces becomes substantially uniform. Then, the tire pieces that have been sliced into pieces are simply placed on the table of the carry-in device, and thereafter, the tire pieces are automatically transferred to the base of the cutting device and can be sent to the accommodating section for cutting. Since the cut tire pieces are carried out by the carry-out device, even large tires can be operated without carrying them. In addition, by providing a wheel-slicing device, even if it is a particularly large tire, the ability of the cutting device to be small can be achieved by cutting each tire piece that has been sliced into two parts. In other words, even a large tire that cannot be cut by the conventional device can be cut into pieces.
