Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a hopper for continuous tire extraction.
For continuous tire extraction, used to automatically supply tires continuously and quantitatively, especially when supplying used tires to a pyrolysis furnace or putting them into a hopper for reuse as fuel etc. Regarding Hotupa.

[Prior art] As a conventional technology of this kind, which takes out old tires that are casually put into a hopper one by one and supplies them to a processing process, there is a method disclosed in Japanese Utility Model Application Publication No. 56-73571 and Japanese Patent Application Laid-Open No.
There is a technique described in Japanese Patent No. 52-111977.

In the prior art described in the above-mentioned Japanese Utility Model Publication No. 56-73571, a slat is provided in the endless chain, a scraper plate is fixed diagonally to the slat, and the scraper plate is fixed between adjacent scrapers in the length direction of the endless chain. The old tires are put in and conveyed to a discharge port provided at a vertically set position, and are discharged from the discharge port through a guide plate and a chute.

In addition, in the prior art described in the above-mentioned Japanese Utility Model Publication No. 52-111977, a rotating body having a locking pin is installed at one end of a water tank into which used tires are placed, and the back side of this rotating body is A cam surface is provided to make the locking pin appear and retract, and a chute and a belt conveyor are installed to move the old tire that has come off the locking pin to another position corresponding to the position where the locking pin retracts, and a belt conveyor is installed. A slat conveyor is provided from the other end to the bottom. Then, the old tires put into the water tank, which is a hopper, are transported to the rotating area of the rotating body using a slat conveyor, and then the old tires are hooked with a locking pin, and the rotating body is rotated and carried to a predetermined position. The locking pin is retracted by the cam surface, the old tire is removed from the locking pin, and the old tire is transferred to the belt conveyor via the chute.

[Problem to be solved by the invention] However, in the prior art described in the above-mentioned Japanese Utility Model Application Publication No. 56-73571, the old tire casually placed in the hopper is removed from the scraping board adjacent to the lengthwise direction of the endless chain. There is no guarantee that the old tires will necessarily fit into the space formed between them, and therefore it is not always possible to take out and transport old tires continuously and quantitatively, and there is a problem in that reliability is low in this respect.

On the other hand, the conventional technique described in the above-mentioned Japanese Patent Application Laid-Open No. 52-111977 has a problem in that the overall structure of the device is complicated and the device is large-scale.

By the way, if the conveyor on the tire import side and the conveyor on the tire output side are combined in a V-shape,
It is possible to downsize the entire device. However, if the conveyor on the tire input side and the conveyor on the tire output side are simply combined in a V-shape, the tires will overlap and stagnate at the bottom of the V-shape, and the conveyor on the tire input side will move from the conveyor on the tire output side to the tire output side. There is a risk that tires may not be transferred to the conveyor.

The purpose of this invention is to be able to continuously and quantitatively take out and supply tires to be processed, one by one, which have been casually thrown into a hopper in large quantities, and to make the entire device smaller, lighter, and simpler in structure. An object of the present invention is to provide a hopper for continuous tire extraction that can achieve the following.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a roller conveyor arranged at a downward slope at the bottom of the tire input slot, a tire hooking pawl, and an upward slope. A hydraulic cylinder is provided at the bottom of the roller conveyor, and a hydraulic cylinder is fitted into the cylinder and is capable of protruding from the tire conveying surface through between the rollers of the roller conveyor. Furthermore, a tire push-up device is provided to help the tires slide off the roller conveyor and transfer to the chain conveyor.

[Operation] In the present invention, a large amount of tires to be processed are casually thrown into the hopper.

The tires placed in the hopper slide down on a roller conveyor arranged at a downward slope.
While sliding on this roller conveyor, most of the tires are placed on their sides and are carried to the bottom of the roller conveyor.

The tires that have reached the lower part of the roller conveyor are hooked by tire hooking claws provided on the chain conveyor at the lower part of the chain conveyor, and are transferred to the chain conveyor one by one and transported.

In the present invention, a tire thrusting device consisting of a fluid pressure cylinder and a piston rod fitted into the cylinder is provided at the bottom of the roller conveyor. This tire push-up device uses a hydraulic cylinder to intermittently project a piston rod from the conveying surface of a roller conveyor, and the piston rod pushes up the tire to help the tire slide off the roller conveyor. assists in transferring tires to the chain conveyor.
As a result, in a device that combines a roller conveyor, which is a conveyor on the tire import side, and a chain conveyor, which is a conveyor on the tire output side, in an almost V-shape, the tires overlap and stagnate at the bottom of the V-shape. It is possible to eliminate problems such as preventing tires from sliding off the roller conveyor or preventing tires from transferring to the chain conveyor.

The tire that is caught on the claw provided on the chain conveyor and transferred to the chain conveyor is conveyed to the upper part of this chain conveyor,
It is sent to the processing stage from the top of the chain conveyor.

As described above, in the present invention, a large number of tires casually placed in a hopper are automatically slid down from the upper part to the lower part of the hopper by a roller conveyor arranged downwardly at the lower part of the hopper. A push-up device installed near the bottom of the conveyor helps the tires slide down, and also helps them transfer to the chain conveyor placed upwards. Tires are hooked at the bottom of the chain conveyor using a chain conveyor, transported to the top, and then sent to the processing process. It can be continuously and quantitatively taken out and supplied to the treatment process.

In addition, in this invention, the roller conveyor on the tire loading side and the chain conveyor on the tire loading side are approximately VV.
Since they are combined in a shape, the entire device can be made compact, and all that is required is to provide a lifting device at the bottom of the roller conveyor and a hook for hooking tires to the chain conveyor. Therefore, it is possible to simplify the structure and reduce the weight of the entire device.

Further, since the tire thrusting device is composed of a fluid pressure cylinder and a piston rod fitted into the hydraulic cylinder, it is possible to reliably help the tire slip off and transfer with a simple structure.

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

Figure 1 is a plan view showing one embodiment of the present invention;
The figure is a longitudinal sectional front view of the same.

In the embodiment shown in these figures, a tire input port 1 which is a hopper, a roller conveyor 2 disposed below the tire input port 1, a tire pushing device 3 disposed below the roller conveyor 2, and a tire pulling device 3 are provided. The chain conveyor 4 includes a chain conveyor 4 having hooks, and side guide rollers 6 and a fluid pressure cylinder 5 arranged on the delivery side of the chain conveyor 4.

In the embodiment shown in the drawings, the roller conveyors 2 are arranged in three rows, as shown in FIG. 1, and each row is arranged with a downward inclination. As shown in FIG. 2, the inclination angle of the roller conveyor 2 is set in the range of 15 to 75 degrees, preferably about 30 degrees with respect to the horizontal plane.

As shown in FIG. 2, the tire thrusting device 3 includes a fluid pressure cylinder 3a fixed to a conveyor frame, etc., and a piston rod 3 fitted into the fluid pressure cylinder 3a.
It is composed of b. The fluid pressure cylinder 3a
causes the piston rod 3b to protrude intermittently.
As a result, the piston rod 3b passes between the rollers of the roller conveyor 2 and protrudes from the conveying surface of the tire 10, pushes up the tire 10, helps the tire 10 slide off from the roller conveyor 2, and also transfers the tire 10 to the chain conveyor 4. It is designed to help people transition.

In this embodiment, as shown in FIG. 1, the chain conveyor 4 has three conveyor elements that are long in the carry-out direction, and one line that is short in the carry-out direction and arranged on both sides of the three conveyor element rows. It consists of a conveyor element. Each conveyor element is provided with tire hooking pawls at equal intervals. In addition, as shown in FIG.
Preferably, it is set at about +45°.

As can be seen from FIG. 1, the roller conveyor 2 on the tire carry-in side and the chain conveyor 4 on the tire carry-out side are combined in a substantially V-shape.

A plurality of side guide rollers 6 are arranged on both sides in the horizontal direction on the delivery side of the chain conveyor 4, and gradually gather the tires 10 toward the center on the delivery side of the chain conveyor 4, thereby controlling the supply of the tires 10. It is designed to limit the location and control the supply amount.

The fluid pressure cylinder 5 intermittently moves the side guide roller 6 in the horizontal direction, and limits the supply position of the tire 10 via the side guide roller 6.
and control of the amount of supply. Note that this fluid pressure cylinder 5 directly pumps the tire 10.
The supply position may be limited and the supply amount may be controlled.

In the hopper for continuous tire extraction of the above embodiment,
A large amount of tires 10 to be processed are casually put into a tire input port 1 which is a hopper using a tire shovel or the like.

Tire 10 inserted into the tire input port 1
The roller conveyor 2 automatically slides down from the upper part of the roller conveyor 2, which is arranged in a downwardly inclined manner at the lower part of the tire input port 1, and reaches the lower part of the roller conveyor 2 while falling sideways.

Incidentally, in this embodiment, the roller conveyor 2 and the chain conveyor 4 are combined in a substantially V-shape, thereby reducing the size of the entire apparatus. the result,
The tires 10 overlap and stagnate at the bottom of the V-shape, and the tires 10 no longer slide off the roller conveyor 2, or the tires 10 overlap the chain conveyor 4.
There is a risk that it will not be transferred and may be transferred. Therefore, in this embodiment, at the bottom of the roller conveyor 2,
A tire thrusting device 3 is provided which includes a fluid pressure cylinder 3a and a piston rod 3b fitted into the fluid pressure cylinder 3a. In this tire thrusting device 3, a piston rod 3b is intermittently projected by a fluid pressure cylinder 3a. As a result, the piston rod 3b
is the tire 1 passing between the rollers of the roller conveyor 2.
0 protrudes from the conveyance surface, pushes up the tire 10,
This helps the tire 10 slide off from the roller conveyor 2 and also helps the tire 10 transfer to the chain conveyor 4.

In the chain conveyor 4, the tires 10 are hooked by claws at the lower part of the chain conveyor 4. The tire 10 hooked on the claw is conveyed from the bottom to the top by the chain conveyor 4. The tire 10, which has been hooked on the claws and conveyed to the upper part of the chain conveyor 4, is moved by a side guide roller 6, which is intermittently moved in the horizontal direction by a hydraulic cylinder 5, on the discharge side of the chain conveyor 4. Alternatively, the fluid is gradually collected directly in the center of the chain conveyor 4 by the fluid pressure cylinder 5, and after the supply position is limited and the supply amount is controlled, it is sent to a processing step such as a pyrolysis furnace.

In this way, a large amount of tires 10 that have been casually thrown into the tire input port 1 are transported by sliding down from the upper part to the lower part by the roller conveyor 2, and the tires 10 are pushed up by the tire pushing up device 3, and the tires 10 are pushed up from the roller conveyor 2. to help the tires 10 slip off and transfer to the chain conveyor 4,
Since the tires 10 are hooked on the lower part of the chain conveyor 4 by the tire hooking claws and conveyed to the upper part to be sent to the processing process, the tires 10 to be processed are casually placed in the tire input port 1. Even if a large amount of tires are input, the tires 10 can be continuously and quantitatively taken out one by one and supplied to the processing process.

[Effects of the invention] As explained above, according to the invention, a large number of tires randomly placed in a hopper are automatically transferred from the upper part to the lower part of the hopper by a roller conveyor arranged downwardly at the bottom of the hopper. A tire push-up device installed at the bottom of the roller conveyor helps the tire slide down, and also helps the tire transfer to the chain conveyor placed upwards. Since the tires are hooked at the bottom of the chain conveyor using a tire hook provided on the chain conveyor and conveyed to the top, the tires are then sent to the processing process. This has the advantage that the tires to be treated can be taken out one by one continuously and in fixed quantities and supplied to the treatment process.

In addition, according to the present invention, the roller conveyor on the tire loading side and the chain conveyor on the tire loading side are combined in an almost V-shape, which has the effect of reducing the size of the entire device. It is sufficient to provide a tire lifting device at the lower part of the conveyor and a tire hooking claw on the chain conveyor, which has the effect of simplifying the structure and reducing the weight of the entire device.

Furthermore, in the present invention, the tire thrusting device is composed of a fluid pressure cylinder and a piston rod that is fitted into the fluid pressure cylinder and can be projected from the tire conveyance surface through between the rollers of the roller conveyor. In a compact device that combines a chain conveyor and a roller conveyor in an almost V-shape, the tires overlap the bottom of the V-shape and become stagnant, making it impossible for the tires to slide off the roller conveyor or causing the tires to reach the chain conveyor. This has the effect of reliably resolving the problem of non-carrying tires with a simple tire thrusting device.
