BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel-slicing device for cutting an outer peripheral portion of a tire in a circumferential direction to separate the tire into two.

[0002]

2. Description of the Related Art In today's car society, the amount of tires of old cars is enormous, and these old tires are generally incinerated. Of course, in order to incinerate the tire, an incinerator having a special structure must be used, and the old tire is transported to such an incinerator. By the way, the old tires are collected at an appropriate place such as a car repair shop or a dismantling factory, or at another collection place, and transported from these places by truck to the incinerator. Since many old tires are piled up and left alone, rainwater collects in each old tire. Then, a bow hula or the like springs in the accumulated water, and mosquitoes are generated from the bow hula, which becomes unsanitary. A tire that is opened on the inner peripheral side because it is mounted on a wheel will accumulate water inside regardless of how it is placed. Further, when an old tire having a hollow inside is transported by a truck, it is very bulky and cannot be loaded with many old tires, and the stability when loaded is not good. Therefore, we handle tires in a sliced state.

On the other hand, since the combustion efficiency of the tire as it is when incinerated is poor, old tires are finely cut and used as fuels to replace coal and petroleum. Also in this case, if the tire is cut without trimming, the tire becomes distorted and the size of each cut piece is not uniform, which affects the combustion efficiency.

By the way, the conventional tire wheel-slicing device is of a vertical type and has a disk-shaped cutter arranged at the upper end thereof, and a tire drum is hung on a tire drum provided below to raise and rotate the tire drum. Press on the cutter. A concentric cutter drum is formed in the cutter, and the tire drum and the cutter drum can perform a wheel-slicing process while rotating the tire. However, since the wheel-slicing device is vertical, the work of hanging the tires on the tire drums is extremely heavy work, and in some cases, even with large tires, it is not possible for one operator to do so. Further, although guide rollers are arranged on the left and right of the cutter so that the wheels can be properly and evenly sliced, only two guide rollers are not sufficient, and the evenly sliced cannot be performed.

[0005]

As described above, the conventional wheel-slicing device has the above-mentioned problems. The problems to be solved by the present invention are these problems, and provide a horizontal type wheel-slicing device that can work without lifting a large tire and can accurately perform a wheel-slicing process regardless of the tire size. .

[0006]

In order to solve the above problems, the wheel-slicing device of the present invention has the following features. The wheel-slicing device of the present invention is configured as a horizontal type, and the tire to be wheel-sliced is laid down on the base plate. The base plate can move up and down, and an opening through which the tire drum appears and disappears and an arc groove are formed in the center of the base plate. The tire drum is pivotally supported by a column protruding upward from the tip of an arm pivotally supported by the main body, and a hydraulic cylinder for pivoting the arm is attached. A disk cutter is horizontally provided on the apparatus body side, and a cutter drum is formed on the upper and lower surfaces of the disk cutter. Further, a guide roller for guiding the tire stands upright on the base plate.

[0007]

Function: A tire to be sliced is placed on a horizontally arranged base plate. Any means may be used to mount the tire here, but the base plate is in a raised position and the tire drum is submerged below the base plate. Therefore, when the tire is placed on the base plate, the tire drum does not become an obstacle. As the tire mounted on the base plate descends, the tire drum projects into the center hole of the tire and stops at the position where the tire is sliced. Since the height of the cutter and the height of the tire drum are set at the same position, the arm is oscillated while rotating the cutter and the tire drum presses the tire against the cutter to cut the wheel.

In this case, the tire drum and the cutter drum clamp the outer peripheral wall of the tire to rotate the tire.
The hydraulic circuit controls the pressing force so that the tire is not distorted by optimizing the pressing force of the tire drum. That is, when the cutter bites into the tire, the pressing force is high, and once the cutter bites, the pressing force is controlled to decrease. Then, when the tire is sliced, the tire drum is returned to its original position, the base plate is lifted, and the sliced tire pieces are removed from the base plate. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show an embodiment of a tire wheel cutting device of the present invention. In the figure, 1 is a base plate, 2 is a tire drum, 3 is a cutter, and 4 is a cutter drum. The base plate 1 is held horizontally, a circular arc groove 5 is formed in the center thereof, and an opening 6 is provided at an intermediate portion of the circular arc groove 5. The base plate 1 is vertically supported by an elevating device 7. It is fixed to the upper end of 8 ... The lifting device 7 uses a pantograph mechanism to operate the cylinder to operate the base plate 1
Although it can be moved up and down, the lifting device 7 is not limited in the present invention. Although the base plate 1 shown in FIG. 2 is in the lowered position and in the wheel-cutting state, the base plate 1 rises and is positioned at least above the tire drum 2 when the tire is loaded or unloaded.

The tire drum 2 is rotatably attached to a column 11 protruding upward at the tip of an arm 10 which is pivotally supported by a main body 9 and can swing. Body 9
The piston rod 13 of the hydraulic cylinder 12 attached to the above is connected to the arm 10, and the operation of the hydraulic cylinder 12 allows the arm 10 to swing in the same horizontal plane. If the arm 10 swings, the tire drum 2 will move, but the pillar 1 that supports the tire drum 2
1 moves along the circular arc groove 5 and approaches the cutter 3.

The arcuate groove 5 is a groove in which the column 11 moves,
The opening 6 is a space through which the tire drum 2 passes when the base plate 1 moves up and down. Therefore, the base plate 1 is above
The position of the arm 10 is determined so that the tire drum 2 can pass through the opening 6 when moving downward. A motor 14 is attached to the main body 9, and the motor 14
The cutter 3 is rotated by this to cut the tire pressed by the tire drum 2, and the cutter drums 4 and 4 are formed on the upper and lower surfaces of the cutter 3 and are integrated with the cutter 3. . Also cutter 3
Is provided at the same position as the tire drum 2.

FIG. 3 is a schematic view showing a wheel-slicing process of the tire 15, but the tire 15 is placed on the ascending base plate 1. It is difficult to lift the tires from the floor and place them, but tires on the same height stand are
It is also possible to slide it in as it is and pull it in. In this case, since the tire drum 2 does not project from the base plate 1, there is no obstacle. The tire 15 mounted on the base plate 1 is arranged so that the center hole is located at the opening 6, and the base plate 1 descends so that the tire drum 2 passes through the opening 6 and comes to the position of the center hole of the lying tire. By the way, stop. Here, the stop height of the base plate 1 can be freely set according to the tire size.

When the arm 10 in the A position swings and moves to the B position, the tire drum 2 drags the tire 15a and presses it against the cutter 3, and the tire 15b has two guide rollers 16,16. While being guided by, rotate and cut into slices. The ring-slicing process is the same as in the case of the conventional device, in which the outer peripheral wall of the tire 15 is held between the cutter drum 4 and the tire drum 2 to rotate the tire 15, but the pressing force of the tire drum 2 is appropriately controlled. So that the tire 15 does not become distorted. That is, if the cutter 3 becomes a large tire, the force with which the cutter 3 bites into the tire 15 becomes about 10 tons, and if this force is maintained and pressed as it is, the outer peripheral wall of the tire is deformed by compression and the entire tire 15 is distorted. Become. Therefore, if the cutter 3 is caught and enters the stationary wheel cutting process, the pressing force is reduced by switching the pressure adjusting valve.

Then, the wheel cutting process is completed and the tire 15
Is divided into two tire pieces, the arm 10 returns to its original position, and in order to move the tire piece to the position of the tire 15a at the time of loading, the arm 10 swings to the C position and then Return to position A. When returning to the position A, the base plate 1 rises, the tire drum 2 passes through the opening 6 and is sunk below the base plate 1, and the tire pieces that have been sliced are carried out. The carrying-out means of the tire piece is not limited to the carrying-in means as well, but if any carrying device is used,
It is necessary to correctly position the tire pieces that have been sliced. Therefore, a guide roller or the like for guiding the tire piece when the arm 10 moves to the C position may be installed at the edge of the base plate.

The tire pieces thus cut into rings may be sent to a tire cutting device for further cutting, and may be moved to another place for storage or loaded on a truck. There are various uses of the piece. As described above, the tire wheel-slicing device of the present invention is provided with the base plate that moves up and down, and the tire drum is pivotally supported on the pillar standing up at the tip of the arm swinging in the same horizontal plane, and the cutter drum is attached to the main body side. It is a horizontal type wheel-slicing device equipped with a cutter provided on the upper and lower surfaces, and the following effects can be obtained.

[0016]

[Effects of the Invention] Since the wheel-slicing device of the present invention is a horizontal type,
The tire is laid on the base plate in a tilted manner, and is subjected to the ring-slicing process while being guided by the guide rollers, so that the tire is stable and can be sliced correctly. In addition, by moving the base plate up and down, it is possible to deal with tires of all sizes, and when loading and unloading tires, the tire drum will sink below the base plate. The tire drum is not an obstacle. Further, since the pressing force of the tire drum that presses the tire is appropriately adjusted, the tire is properly sliced without being distorted during the trimming process.
