It is composed of a storage means for the raw tire receiving tray 2 including a chain 4 and a sprocket 5. Frame 1
The outer frame surface is made of a substantially box-shaped steel skeleton, and forms a stock area in which 12 raw tire receiving trays 2 are stored. Wheels 6 are attached to the bottom surface of the frame 1, and the carriage D is movable. A large number of sprockets 5 are rotatably mounted inside the left and right sides of the frame 1, and the left and right chain chains 4 which are closed orbits are engaged with these left and right sprockets 5 and are driven to circulate by a motor 3. Twelve raw tire receiving trays 2 are attached at equal intervals. The motor 3 drives the chain 4 so that the raw tire receiving tray 2 circulates in the direction of arrow A by the supply of a power source such as a battery (not shown) mounted on the carriage D itself or an external power source. . The raw tire receiving tray 2 is pitch-fed by the motor 3 at regular intervals attached to the chain, and always stops at the fixed position P. This fixed position P is set to a position that enables loading by an automatic loader of a molding machine and picking up by a vertical loader of a vulcanizer. At this fixed position P, the raw tire T is placed on the raw tire receiving tray 2. Acceptance and removal are carried out.

Next, details of the raw tire receiving tray 2 will be described with reference to FIG. As shown in FIG. 3, a fixing member 8 is fixed to the chain 4 that engages with the left and right sprockets 5, and a pin 7 is fitted to the fixing member 8. The raw tire receiving tray 2 has the pin 7 at the top of itself.
It is suspended rotatably by. Since the center of gravity of the raw tire receiving tray 2 is below the position of the pin 7, the raw tire receiving tray 2 draws a locus such that the chain 4 meanders through the many sprockets 5 by the driving of the motor 3.

Thus, when the raw tire T is loaded horizontally on the raw tire receiving tray 2 with the center line C as the core, a relatively small raw tire is supported by the eight-sided flared surface of the centering cone 9 and relatively. Large green tire has ring 1 on the outer peripheral surface
Supported by 0. Therefore, the raw tire receiving tray 2 can receive raw tires of many different sizes without requiring adjustment for each size, and can maintain the same horizontal state as the core when loaded.

Next, a series of operations for continuously receiving, storing, and unloading the raw tire T by the carriage D will be described. As shown by the chain double-dashed line in FIG.
Is held in a horizontal state by a raw tire automatic loading / unloading device R similar to the automatic loader of the molding machine or the vertical loader of the vulcanizer. The dolly D makes the empty raw tire receiving tray 2 stand by at the fixed position P, and automatically adjusts the center position of the fixed position P of itself (the position of the center line C of the raw tire receiving tray 2 at the fixed position P) to the automatic raw tires. The loading / unloading device R is arranged so as to coincide with the center thereof. In this state, the raw tire T is supplied onto the raw tire receiving tray 2 by the raw tire automatic loading / unloading device R. The raw tire receiving tray 2 that has received the raw tire T is pitch-fed by the motor 3 in the direction of the arrow A and stored in the stock area, and at the same time, the empty raw tire receiving tray 2 waits to move to the fixed position P. By repeating the same operation, 12 raw tires are received and stored one after another. Next, the raw tire receiving tray 2 on which the raw tires T are placed for carrying out is made to stand by at a fixed position P. Then, the raw tire automatic loading / unloading device R carries out the unloading. The empty raw tire receiving tray 2 is pitch-fed in the same direction as the arrow A when it is received by the motor 3, and the raw tire receiving tray 2 on which the next raw tire is placed moves from the stock area to the fixed position P. Be waited for. The raw tires thus received are carried out one after another. As described above, since the raw tire receiving tray 2 maintains the same core and horizontal state as when the raw tire T is received, it is in the same state as when the raw tire automatic loading and unloading device R is loaded. Can be loaded and unloaded.

In the above embodiment, twelve raw tire receiving trays 2 are arranged, but the number can be further increased by extending the frame. The motor 3 as a driving device may be replaced by an air cylinder, the chain 4 may be replaced by a belt, and the sprocket 5 may be replaced by a belt pulley. The raw tire receiving trays 2 are arranged at equal intervals, but they may not be arranged at equal intervals as long as the raw tire receiving trays 2 are controlled so as to accurately stop at the fixed position P. Since the dolly D only needs to have a movable structure, it does not have to have wheels on its own as long as it can be moved by another carrier or forklift. In addition, it may have the function of an automated guided vehicle itself.

Next, an embodiment of an automatic raw tire feeding and feeding system during molding and vulcanization according to claim 4 will be described with reference to FIG. In FIG. 4, reference numeral S is a molding machine,

1 has a structure similar to that of the vertical loader K1 and holds the raw tire T in a horizontal state with the center line C1 as a center and vertically moves up and down to load and unload the raw tire T. You can do it. An area for waiting an empty truck is provided on the upstream side of the loading position of the raw tire T by the automatic loader S1 of the molding machine S, and an area for waiting the finished truck is provided on the downstream side. The automated guided vehicle J is an unmanned guided vehicle that is embedded in the floor or can travel along a route drawn on the floor according to a command from a computer device (not shown).
In the present embodiment, the low floor type is a car D
Although a type that lifts up and transports is used, a lift car type or the like may be used. First, the automated guided vehicle J places the empty raw tire truck D at the loading position of the raw tire T from the standby area. That is, the center of the fixed position P for receiving the raw tire of the truck D is arranged at a position that coincides with the position of the center line C1 of the automatic loader S1. The raw tire T is picked up by the vertical loader K1 as it is to the automatic loader S1, and the vulcanizer K is used.
It is horizontally gripped in a state in which the release agent coating process on the inner surface and the circumferential alignment have been completed in advance so that the vulcanization process can be performed by inserting into the inside. Next, the raw tires T are loaded on the raw tire receiving tray 2 of the truck D by the automatic loader S1. The dolly D stores the raw tire receiving tray 2 in the stock area by its own storing means, and moves the next empty raw tire receiving tray 2 to a fixed position for standby. The automatic loader S1 grips the next raw tire and sequentially loads the raw tire T on the carriage D. During this time, a battery (not shown), which is the power source of the motor 3 of the carriage D, is automatically charged. At the time when the predetermined number has been stacked, the automated guided vehicle J moves the carriage D to the actual carriage standby position. And before the next green tire is molded,
The trolley D that has been waiting at the standby position of the empty trolley in advance is placed at the fixed loading position. Next, the automatic carrier J
The actual carriage D is automatically conveyed from a standby position to a front of a predetermined vulcanizer K according to a command from a computer (not shown), and a position where it can be picked up by the vertical loader K1, that is, a center of a fixed position P of the carriage D is set. The vertical loader K1 is arranged at a position corresponding to the position of the center line C2. Then, the raw tire receiving tray 2 on which the raw tires T have been placed is brought to a standby position at a fixed position P for unloading. Already a raw tire T
Is loaded in a state where it can be immediately vulcanized by the automatic loader S1, and therefore the vertical loader K1 picks up the raw tire T while keeping the same state as when it was loaded by the automatic loader S1, and directly in the vulcanizer. Can be inserted into. In this way, the raw tire T
When the trolley D is emptied and the trolley D is emptied, the trolley D is automatically conveyed again to the standby position of the vacant trolley of the predetermined molding machine S by the automatic conveyance vehicle J, and is circulated and used. As described above, the raw tire can be automatically conveyed and supplied from the molding machine to the vulcanizer.
