, 45 rotatably support support rods 47 and 48, and a hoop 46 is attached to the support rods 47 and 48 to support the hoop 46 with its installation plane horizontal.

The hoop 46 is formed into a circular shape with a diameter slightly smaller than the outer diameter of the green tire so that the green tire can be placed on it.

A crankshaft 50 is provided at the tip of one of the support rods 47 in parallel with the support rod 47 via a crank arm 49 bent at right angles to the installation plane of the hoop 46. This roller 52 is inserted into the guide groove of an oblong roller guide 54 attached around the chain guide 64 by the support frame 17 of the stand 16.

As shown in FIG. 3, the roller guide 54 is located at a position O1 which is a distance t (the axial distance between the roller 52 and the support rod 47) above the axis of the horizontal shaft 18 and a distance t from the axis of the horizontal axis -20. The straight line portion 54 a between the straight line portion 54 a and the chain guide 64 is equal to the horizontal distance between the axis of the support rod 47 and the center line of the chain 60 . Further, the circular arc portions 54b and 54C above and below the 0 and 02 positions of the roller guide 54 are machined on the horizontal axis 18 with their center lines at the centers of 01 and Oz'f, respectively.

A plurality of green tires placed on two hoops 46 can be sequentially and continuously supplied to the vulcanizer.

The hoop 46 does not necessarily need to be transported by an endless chain 60, 62 as in the previous embodiment, but a timing belt or other endless conveyor may be used.

In addition to the motor with a speed reducer of the above-mentioned embodiment, a rotary cylinder, an air cylinder, or the like may be used as a drive source for a drive device for a hoop transfer chain or other endless conveyance body.

As described above, the present invention has a plurality of hoops mounted on a movable truck, supported by a support rod having an extended crankshaft, and an endless support rod rotatably supporting the support rod. The structure includes a device that transports the hoop by guiding a roller that is attached to the conveyor and fitted onto the crankshaft of the support rod using an oblong roller guide. It is possible to transport the tires while maintaining a horizontal state even in the arcuate portion of the roller guide, and the cart has two functions: transporting a plurality of green tires and supplying the green tires to the vulcanizer. In addition, this invention has a structure in which the cart is positioned and determined in the vulcanizer, and the endless conveyor for hoop transfer is driven by the drive device on the vulcanizer side, so that the conventional manual work is not required. It becomes possible to automatically supply green tires without having to transfer the green tires.

Therefore, according to this invention, it is possible to increase the number of vulcanization machines per person by five workers, which not only greatly improves work efficiency, but also allows the trolley itself to temporarily store green tires. Coupled with the fact that raw tires can be stacked on top of each other, the floor space per individual tire is reduced, and the weight can be reduced as there is no drive source per truck. Therefore, there is an effect that an inexpensive green tire supplying device can be obtained as a whole.
