Description

[Detailed description of the invention] This invention relates to a waste tire alignment and supply device, and its purpose is to
There is a particularly large amount of waste such as automobile tires, and among a large number of waste tires with different diameters, waste tires with a specified diameter or less are automatically sorted and arranged in a transfer position, and then sent to the waste tire processing equipment according to the diameter. An object of the present invention is to provide a waste tire alignment and supply device that is convenient for supplying waste tires according to supply amount or destination.

The present invention will be explained below with reference to the drawings.

A rectangular frame 9 made of H-shaped steel struts 1, horizontal members 2 to 8, etc. are joined as appropriate, and the main frame 1a and the auxiliary frame 1b are bolted to each other at the flange 10. The waste tire receiving container 11 is fixedly supported.

The container 11 has side plates 12 in contact with the inside of the frame 9, a front wall plate 13 inclined at an angle of about 10 degrees with respect to the vertical, and a front wall plate 13 inclined at an angle of about 2 degrees with respect to the vertical.
It is formed by joining together the rear wall plate 14 inclined at 0° and the bottom plate 16 that continues to the lower curved part 15 of the rear wall plate 14, and the inner corners of both sides of the rear wall plate 14, the curved part 15, and a part of the bottom plate 16 A rail 17 is fixed to the front wall plate 13, and a curved plate 18 is fixed to the lower part of the front wall plate 13 higher than the bottom plate 16, and its central part is supported by a vertical support plate 19.

A frame 21 having columns 20 is mounted on the main frame 1a, and a support member 22 whose upper part is vertical is fixed to the frame 21. 2
The upper extension portions of the side plates 12 and the rear wall plate 14 are fixed to the third or the like to form a vertical path 24 that is smoothly continuous on one side in the rear wall plate 14.

The width a of the vertical path 24 is set to a size that allows the scrap tires T to be aligned and supplied to pass through in a vertical position, and the width of the lower part of the vertical path 24 expands downward, and the rail 17 extends from the expanded portion to the vertical path. Extend to the top of 24.

A rotating shaft 27 to which a pair of sprockets 26 is fixed is supported by left and right take-ups 25 provided on the frame 21, and l pairs of sprockets 28 and 29 are respectively fixed to the frame 9 below the container 11. The shaft 30, 31 is supported, and the upper part of the sprocket 28 is exposed in the container 11 through the cutout part 32 of the bottom plate 16,
Sprockets} 26, 28, and 29 are hung with two endless upward feeding chains 33.

Both ends of a flexible band 34 made of slats or wire mesh that can be bent in the transport direction are attached to the links of the chain, and a large number of scraping plates are attached to the chain links or the slats at a pitch slightly larger than the outer diameter of the waste tire T. Fix both ends of 35.

The chain 33 includes the bottom plate 16, the curved part 15, and the rear wall plate 14.
It is guided and supported by rails 17 in the horizontal movement portion and the inclined upward movement portion along.

The rotating shaft 30 extends outside the frame 9, and a gear 36 with a built-in one-way clutch is fixed to the extended portion, and a rack 37 that meshes with the gear is reciprocated by a hydraulic cylinder 38, thereby keeping the chain 33 constant in the direction of the arrow. Move intermittently.

When various types of waste tires with different diameters are put into the container 11,
The chain 33 curves and moves parallel to the inner surface of the container 11 due to the weight of the tire, and the scraping plate 35 pushes the waste tire upward from the curved portion 15.

In this case, the scrap tire T that has completely entered the gap between the scraping plates 35 is transported upward in a stable inclined position with its side surface in contact with the flexible band 34; As shown in the figure, the waste tire T1 with the outer diameter assumes an unstable position away from the flexible band 34 and falls from the scraper 35.

The width of the scraping plate 35, the angle of attachment to the chain, the inclination angle of the rear wall plate 14, etc. are appropriately determined according to the size, shape, etc. of the waste tire so as to ensure the above-mentioned falling.

In this way, only the tires that fall within the spacing between the scraping plates 35 are transported onto the vertical path 24.

In this embodiment, a traversing device 39 is provided on the frame 21 above the vertical path 24, which allows up to three scrap tires T of the largest diameter to be simultaneously lifted by one scraping plate 35.

The cross-transfer device 39 includes a side plate 40 that guides the side surface of the waste tire T, a pair of horizontal rails 41 supported above the side plate 40, a truck 42 that moves on the rails, a hydraulic motor 43 mounted on the truck, and A small gear 45 having a rack 44 and fixed to the output shaft of a motor 43 meshes with the rack 44 to cause the cart 42 to reciprocate.

The timing of this reciprocating movement is adjusted so that it is carried out during a period during which the chain 33 is stopped moving when the scraping plate 35 substantially coincides with a predetermined level of the traversing device 39 and stops.

When the chain 33 is moving, the truck 42 is stopped on the left end extension 46 of the rail 41 in FIG.
A pushing plate 47 attached to the trolley 42 is stopped on the left side of the waste tire T that has risen from the vertical path 24.

The pushing plate 47 has a structure in which a large number of rollers 49 are pivotally supported on a frame 48 whose lower part is curved forward so as to press downward from the center of the waste tire T, and when the waste tire T is pushed by the pushing plate 47, it smoothly moves. Transfer.

When the chain 33 stops, the truck 42 starts moving to the right, and the pushing plate 47 pushes the waste tires T into the chute 50 in one line.

When the cart 42 returns to its original position after extrusion, the chain 33 is activated again to feed the next waste tire into the traversing device 39.

The chute 50 is supported by a frame 51 and tilts downward, and has a width for holding and transferring the waste tires T in one row, and a cross-transfer device 3.
It has a length that can store more waste tires T than are pushed out at one time from 9, and has a gate 52 at the end of the chute.

A waste tire diameter detecting device 53 is provided on the shoe 50 at a position in front of the gate 52 by a storage interval of one waste tire of approximately the maximum diameter.

The diameter detection device 53 has a rotary arm 54 that projects into the chute 50, and when the arm 54 engages with the waste tire T and rotates counterclockwise, it reaches a rotation angle corresponding to the tire diameter. Generates a corresponding signal.

This signal controls the opening time of the gate 52 to adjust the amount of waste tires supplied to the waste tire processing device, or
It is used for control such as selectively opening and closing a plurality of gates provided downstream from 2 to sort waste tires by diameter.

The present invention has the above-mentioned structure, and automatically sorts out only those with a predetermined diameter from among the various waste tires placed in a container.
In addition to being able to be discharged in an upright position, it is advantageous in controlling the supply amount to a waste tire processing device or controlling the supply of tires by diameter.
