The normal rotation sorter 17 can be switched between a horizontal position shown in FIG. 3 and a vertical position (not shown). For example, when the tire receiving frame 19 receives the front tire in the vertical position, the tire receiving frame 19 is switched to the horizontal position by the forward rotation machine 20 and holds the tire on the roller 21 in the horizontal direction. Further, when the pair of conveyor belts 23 are raised and switched to perform the conveying operation, the tires are fed out in a direction different from the feeding direction of the inclined rollers 18 and the rollers 21 by 90 degrees, that is, toward the tire assembly stacking device 10. On the other hand, if the tire receiving frame 19 receives the spare tire in the vertical position, the tire receiving frame 19 is switched to the horizontal position by the normal rotating machine 20 and holds the tire on the roller 21 in the horizontal direction. Then, the roller 21 is operated so that the spare tire can be fed toward the spare tire feed roller 22. After that, the spare tire reaches the direction changer 70 having the same structure as the roller 21 and the pair of conveyor belts 23 in the forward distribution machine 17, and is supplied to the second-stage stacking process section 15 where the spare tire is spared. Only tires are stacked in 4 layers.

When the gripping cylinder 51 is switched from the non-actuated position to the actuated position, the gripping means 35 can grip the tire by bringing the pair of movable gripping members 34, 34 closest to each other. In this case, the sandwiching interval is appropriately adjusted according to the tire diameter processed by this device. During the adjustment, the length of the front lever 552 and the downward lever 54 can be increased or decreased to easily adjust the holding interval.

As shown in FIGS. 1 and 2, the tire deviation correcting means 60 is capable of abutting against the tires of the conveyance path R during operation so as not to interfere with the conveyance rollers 30 forming the conveyance path R.

The movable stopper 31, the lifter 33, and the holding means 35 are controlled to achieve the mode.

That is, the controller 36 switches the movable stopper 31 from the retracted position hb to the stopper position ha before each tire reaches the stacking position P1 while receiving the supply of two front tires and two rear tires. .. When the tire reaches the stacking position P1, the shift correction cylinder 65 is driven to align the tire with the stacking position P1. Subsequently, the holding cylinder 51 is driven to hold the tire by the pair of movable holding members 34, 34. Further, the lifter lift cylinder 45 is driven to switch the lift table 32 to the upper position H2 from the lower value H1 to raise the tire by the lift stroke S only. After this, the controller waits for the next tire to be delivered. When the next tire is fed, the shift correction cylinder 65 corrects the tire by shifting it to the stacking position P1, and the holding means 35 is opened to place the tire being held on the next tire.

After that, the lifter 33 descends and reaches the lower value H2. Here, the pinching means 35 enters the pinching operation to pinch the next tire. After that, the lifter 33 again reaches the upper position H2, holds the two stacked tires, and waits for the next tire to be fed to the lower value H1. In this way, when the stacking mode is repeated and the controller 36 completes the stacking of the two front tires and the two rear tires, the movable stopper 31 is switched from the stopper position ha to the retracted position hb, and the transport roller 30 is moved. The feeding operation is performed, and the four stacked tires are fed to the conveying roller 30 and the inclined roller 24 on the downstream side thereof.
