DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rubber tire lift device suitable for use when transporting automobile tires to high places.

For example, when old tires are lifted to a high location using appropriate lift means and dropped into a cement firing kiln as fuel, the tires cannot be burned efficiently unless the tires are introduced quantitatively. .

The purpose of the present invention is to provide a tire lift device capable of quantitatively and efficiently lifting the above-mentioned rubber tires, and its features include a lift means for sequentially transporting the rubber tires upward; , a rubber tire lifting device comprising a rubber tire positioning means provided with a base of the lifting means, and a feeding means for feeding a predetermined number of the rubber tires to the positioning means, the lifting means having a rubber tire positioned at a predetermined interval. Place the hook,
The positioning means is provided with means for moving the rubber tire toward the hook when the hook moves to a position where it can engage with the rubber tire, and the bottom of the positioning means is moved from both sides in the tire feeding direction toward the center. a plurality of guide rollers are arranged in a vertical direction along the tire feeding direction on the rear side of the positioning means;
The hook of the lifting means is engaged with the inner circumference of the rubber tire sent into the positioning means by the feeding means, and the rubber tire is lifted and transported.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 1 conceptually and partially shows an embodiment of a lift device according to the present invention configured to lift and transport tires. The provided tire 5 positioning means 3 is configured to position the tire 5 on the positioning means 2.
Feed means 4 is a conveyor adjacent to the feed means 3, which is disposed on the side of the positioning means 2 to feed the pieces one by one.

The lift means 1 is made up of support columns 1 on both sides, which are inclined at an appropriate angle, as shown in FIG.
a and an endless body 1b such as a chain wrapped around the support 1a at the intermediate portion of the support 1a.
and a plurality of hooks 1c attached to the endless body 1b at regular intervals from each other, the endless body 1b being configured so as to be movable in the direction of the arrow at an appropriate speed by an electric motor or the like (not shown). The hooks 1c are supported by guide rails 1d shown in FIG. 1 so that their tips protrude an appropriate length forward, i.e., toward the positioning means 2.

The positioning means 2 includes a bottom part 2b formed by arranging a large number of rollers 2a, and pillars 1 of the lifting means on the front side and rear side of the bottom part 2b, respectively.
Guide rollers 2 arranged substantially parallel to a
c and 2d, a wheel 2f attached to the pedestal 2e of each of the above components, a rail 2g having a U-shaped cross section provided to guide the wheel 2f toward the lift means 1 side or away from the means 1, and the above-mentioned It consists of a hydraulic device 2h provided to move the pedestal 2e a predetermined distance along the rail 2g, and the roller group 2a constituting the bottom 2b moves the bottom 2b downward from both sides toward the center ( (see FIG. 1), and are arranged so as to be substantially orthogonal to the support column 1a of the lifting means 1 (see FIG. 2).

6 is a sensor that detects when the hook 1c passes near the base of the column of the lift means 1;
7 further includes a sensor for detecting whether or not the tire 5 is present in the positioning means 2;
2 indicates sensors for confirming that the tire 5 has completely come out of the positioning means 2.

On the other hand, the feeding device 3 includes a pedestal 3a whose upper surface has a dogleg shape in longitudinal section;
The pedestal 3a is normally positioned as shown by the solid line.

Next, the configuration of the top portion of the lift means 1 and the conveyance path following the top portion will be explained. As shown in FIG. 4, an accelerating roller 1e (the driving means thereof is not shown) is suitably mounted on the top of the lift means 1, which rotates so that the tire 5 can be fed at a faster speed than the hook 1b. They are arranged over the interval. A transport path 8 of a predetermined length is provided in the lateral direction from the end of the acceleration roller 1e, and a drop path 10 for the tires 5 is provided between the end of the transport path 8 and the cement baking kiln 9. There is.

At one end of the conveyance path 8, the acceleration roller 1
Rollers 8a for posture control are arranged at sequentially changing arrangement angles so that the tires 5, which are thrown in diagonally vertically by e, are positioned almost horizontally, and the tires 5 are placed at the other end of the descending path 10. Posture control rollers 8b whose arrangement angles are adjusted so as to be introduced into the conveyance path 8 in a substantially vertical direction are provided, and guide rollers 8c are provided on both sides of the conveyance path 8. Note that this conveyance path 8 constitutes a conveyor with rollers 8d disposed at its bottom, and this conveyor is driven to convey the tires 5, but the tires 5 are not moved toward the descent path 10 side due to their own weight. The bottom surface may be inclined at an appropriate angle to facilitate conveyance. On the other hand, in the descending path 10, rollers 10a are arranged along the conveying path similarly to the conveying path 8, and guide rollers 10b are arranged on both sides thereof.

The belt conveyor 4 shown in FIG. 1 is a so-called accumulation conveyor, and each roller constituting it is tilted at an appropriate angle in the same manner as the roller 2a constituting the bottom portion 2b of the positioning means 2. I have let you. Although not shown, guide rollers as shown in the positioning means 2 are also provided on both sides of the conveyor 4 and the feeding means 3.

The lift device according to the present invention having the above configuration operates as follows. That is, when used tires 5 as conveyed items are placed one after another on the conveyor 4 shown in FIG. 1, the preceding tires 5 are transferred from the terminal end of the conveyor 4 onto the feeding means 3 in the manner shown in the figure. At this time, since the tip of the pedestal 3a of the feeding means 3 projects obliquely upward, the tire 5 is not sent toward the positioning means 2 from the pedestal 3a.
However, when the sensor 7 shown in FIG. 2 detects that no tire is present in the positioning means 2, the hydraulic system 3b
c to rotate the pedestal 3a to the position shown by the broken line, thereby rotating the tire 5 on the pedestal 3a.
is sent into the positioning means 2. Note that the pedestal 3a immediately returns to its original position after the rotational operation.
Place the next tire 5 on the pedestal 3a.

Since the bottom part 2b of the means 2 is inclined, the tire 5 that has entered the positioning means 2 is placed in the second
As shown in the figure, it is positioned leaning against the roller 2d. In this state, when the hook 1c of the lift means passes near the sensor 6, the sensor 6 outputs a signal to start the timer means 11, and the timer means starts measuring time. This timer means can set the time arbitrarily, and in this device, it measures the time from the time when the hook 1c passes near the sensor 6 to the time when it moves to the position indicated by the hatch in FIG. It is set like this. Therefore, when the hook 1c moves to the position indicated by the hatch, a signal is output from the timer means 11, and this signal operates the hydraulic system 2h.
As a result, the positioning device 2 is moved to the lift means 1 by the hydraulic device 2h as shown in FIG.
moved to the side. When the hook 1c rises in the state shown in FIG. and then moved upward. When the tire 5 has completely come out of the positioning device, the sensor 12 detects this, and the signal from the sensor 12 resets the timer means 11. This causes the hydraulic system 2h to return to its original position and move the positioning means 2 to its original position as shown in FIG. At this point, there is no tire 5 in the positioning means, so the feeding means 3 rotates again to feed the next tire 15 into the positioning means 2, and the next tire 15 is then rotated in the same order as above. 5 is suspended from the hook 1c.

Although the timing operations among the lift means 1, positioning means 2, and feeding means 3 are performed more strictly in practice, they have been explained in principle here. Furthermore, the sequence for performing the above-mentioned timing operation is omitted because it can be constructed using a conventional circuit.

The tires 5, which have been successively suspended from the hooks 1c of the lift means 1 as described above, are accelerated by the acceleration roller 1e at the top of the lift means 1, and are thereby removed from the hooks 1c and placed on the transport path 8. is inserted into one end of the and the roller 8
After its attitude is corrected to almost horizontal by the roller 8a, it moves along the conveyance path 8, and at the other end of the path 8, it is thrown into the descending path 10 while changing its attitude vertically by the roller 8b. be done. The fuel is then guided downward along the descent path 10, and is introduced into the cement kiln 9 from the lower end of the path 10 as fuel. In the above embodiment, the rubber tires are fed into the positioning means 2 one by one, but it is of course possible to feed a plurality of rubber tires into the positioning means 2 by the feeding means 3. . In that case, the plurality of rubber tires fed into the positioning means may be suspended one by one from the hook 1c, or all of them may be suspended from the hook 1c, but in either case, the rubber tires may be suspended from the hook 1c. This can be easily achieved by appropriately setting the length of and the movement stroke of the positioning means.

In the rubber tire lift device according to the present invention, hooks are disposed at predetermined intervals on the lift means, and when the positioning means moves to a position where the hook can engage with the rubber tire, the rubber tire is lifted. In addition to providing means for moving the position to the side, the bottom part of the positioning means is formed so as to descend from both sides in the tire feeding direction toward the center, and a plurality of guide rollers are provided on the rear side of the positioning means in the tire feeding direction. arranged vertically along the
The hook of the lift means is engaged with the inner circumferential portion of the rubber tire fed into the positioning means by the feed means, and the rubber tire is pulled up and transported. The slope on the bottom and the guide rollers on the rear side ensure smooth movement and accurate positioning.
In this way, a large number of rubber tires can be efficiently and reliably installed in the hoisting standby position one after another, and the rubber tires can be quantitatively and efficiently hoisted. For example, as shown in the embodiment, if this device is used when old tires are used as fuel to be transported into a cement firing kiln, the tires can be quantitatively transported into the kiln. That is, if the old tire is simply conveyed to the base of the lift means by the belt conveyor and then lifted by the lift means, depending on the position of the hook of the lift means, the hook may act to push the tire away. As a result, problems occur such as the tire being overturned or the hook passing by without hanging the tire.However, with the device of the present invention, such problems do not occur, so the old tires can be efficiently and quantitatively removed. It can be transported by ship. In addition, it has the advantage that it can be applied to tires of various diameters.

Note that the device of the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, instead of the feeding means shown in the above embodiment, a stopper means for temporarily storing the rubber tires may be provided on the accumulation conveyor, and this may be operated at the same timing as the feeding device. . It is also possible to lift the rubber tires while periodically feeding the hooks of the lift means from a predetermined number by appropriately setting the set time of the timer means, and in this way, the feeding speed of the lift means can be adjusted. It is possible to adjust the lift amount without changing it.
