[Industrial applications]

 The present invention relates to a cutting line device for cutting old tires into small pieces for convenience of transportation and a wheel cutting device for cutting the tires into pieces before starting a cutting process.

[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 variability expands. Even if the cut piece used as fuel is as uniform as possible, it not only facilitates handling but also affects the 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 cutting device, the tire cut pieces are finer and more uniform, and the workability is high, and the device itself is relatively large. Provided are a compact cutting line device and a ring cutting device.

[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. If the size of the old tire to be cut here is small, the above-mentioned loading device can be omitted, and the tire pieces cut by the wheel-cutting device can be lifted by hand and placed on the base of the cutting device.

By the way, in the above-mentioned wheel-slicing device, a swing arm is attached, a cutter is horizontally attached to the tip of the arm, and a tire drum is rotatably supported on both sides of the cutter. A groove is formed on the outer periphery of the tire drum, and a support board is provided below the tire drum, and the height of the support board (the distance from the tire drum) can be adjusted. If the tire to be sliced is placed on a support plate and pressed against the tire while rotating the cutter, the tire rotates with the cutter and is torn. Since the tire drums are provided in two places, while one is used for wheel-slicing, another tire is placed on the support board and prepared, and when the wheel-slicing process is completed, the wheel-slicing on the opposite side is started. The torn tire pieces are then placed on the base of the cutting device.

The basic structure of the cutting device has a part common to the conventional device, in order to attach the blade to the lower surface of the blade base, press the tire at the time of cutting, and remove the cut tire cut piece from the blade. A stripper is provided, and the blade base moves up and down in conjunction with the hydraulic cylinder. A tire accommodating portion is provided below the blade base body, and the base of the accommodating portion is extended to the left and right (front and rear) thereof, and a chain conveyor running along the base is arranged. The chain conveyor attaches the feed member, and the feed member slides on the base, and the feed 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. The cut pieces are sent again by the sending member and fall from the unloading side base to the unloading device. This unloading device is also a kind of conveyor.

By the way, a carrying-in device may be installed in the cutting line device of the present invention as needed, and the carrying-in device is provided between the wheel-slicing device and the cutting device. This device has a table that moves up and down and a carry-in arm. The table is raised by the parallel link mechanism to the level of the carry-in base of the cutting device while keeping it horizontal (substantially horizontal). The loading arm is slidably attached, and the tire piece lifted on the table is drawn into the loading base. Here, the raising / lowering movement of the table and the slide means of the carry-in arm do not matter.
