A dog 14 provided at the lower part of the trolley 11 is engaged with the chain 11, and the endless chain 13 is driven to reciprocate on the rail 10 using a forward/reverse rotating motor M1 as a drive source.

As shown in FIGS. 2 and 3, the unmanned transfer vehicle B consists of a cart 21 mounted on a pair of rails 20 laid on the same plane as the rails 10 of the unmanned transport vehicle A. The wrap L is equipped with a pair of support rods 22 that support both ends of the wrap rod R (rod inserted through the core of the wrap), and the upper part of the support rod has a pair of mounting rods attached to a rotatably supported horizontal shaft 23. A swinging member 28 is fixed to a shaft that is connected to a piston rod of a pair of hydraulic cylinders 25 supported on a member 24 and has a fan-shaped gear 27 fixed thereon that meshes with a pinion 26 fixed to one end of a horizontal shaft 23.
One end of the swinging section is connected to a piston rod of another hydraulic cylinder 29, and the pair of support rods 22 are raised and lowered by the operation of the pair of hydraulic cylinders 25, and are made to swing by the operation of the hydraulic cylinder 29. . A dog 31 attached to the lower part of the truck 21 is engaged with the endless chain 30, and the endless chain 30 is driven using the forward and reverse rotation motor M2 as a drive source, thereby causing the rail 21 to travel back and forth. The endless lap stopper C has a large number of chain wheels 4 as shown in Figs. 4, 5, and 6.
It is composed of a pair of endless chains 41 extending in a three-dimensional meandering manner around the 0, and uses a forward and reverse rotation motor M3 as a drive source to drive the pair of endless chains 41.
It is provided with a receiving member 42 on which both ends of are placed, and this receiving member is connected by a connecting rod 43. The wrap L stored in the endless wrap stocker is taken out from the opposite side of the storage side.

(Action of invention) Next, the operation of the method of the present invention will be explained.

The lap L formed by the lap machine 1 is transferred to a lap weighing machine H, where it is weighed and recorded by type.
After this work is completed, the measuring device H is rotated as shown by the chain line in FIG. 2, and the lap L is transferred onto the lap receiving tray 12 of the unmanned carrier A. After this transfer operation, the lap is surrounded with a sheet that has been placed on the tray in advance.

Next, a start signal is sent to the unmanned transport vehicle A following a key-in by the operator to a computer in which the type of lap L and the arrangement number of the endless lap stocker C in which the lap is stored are set in advance. In synchronization with this signal, the empty transfer unmanned carrier B waiting at one end of the line Y is started and temporarily stopped at the line X position of the unmanned carrier vehicle on which the lap L has been moved. Then, a transfer operation is performed to transfer the lap L on the unmanned carrier A to the transfer unmanned carrier B. In this transfer operation, as shown in FIG.
6 to swing the pair of support rods 22 counterclockwise on a line connecting the center of the wrap L on the automatic guided vehicle A and the center of the horizontal shaft 23, and then operate the pair of hydraulic cylinders 25. The support rod 22, which is in the lowered state, is raised to bring the recess provided at its tip into contact with both ends of the rod rod R. Thereafter, the hydraulic cylinder 29 is operated again to return to its swinging position in the clockwise direction, and the pair of hydraulic cylinders 25
With this operation, the support rod 22 carrying the wrap L is lowered.

After the transfer operation of the lap L mentioned above is completed, the empty unmanned transport vehicle A returns to the standby position, and the unmanned transport vehicle B that transferred the lap moves to the command number position of the endless lap stocker C. and stop.

Next, the wrap L on the unmanned transfer vehicle B is transferred and stored in the endless lap stocker C. This action is to transfer the lap L from the unmanned transfer vehicle A to the unmanned transfer vehicle B. This is performed by operating a pair of hydraulic cylinders 25 and another hydraulic cylinder 29 in the same way as the above operation. First, the pair of support rods 22 supporting the lap L are swung up and raised in the clockwise direction, that is, on the line connecting the receiving member 42 provided on the endless lap stocker C and the horizontal shaft 23. Place the lap rod R of the lowering lap L on the receiving member 42 of the endless lap stocker C. After the wrap L is transferred to the receiving member 42, the pair of support rods 22 are lowered again and swung back to their original positions. Then, the empty transfer unmanned carrier B is returned to the standby position.

The series of operations described above are performed fully automatically in response to command signals from a computer, and a description of this electric circuit will be omitted.

The endless lap stocker C that has transferred the lap L is operated by an endless chain 41 and stops in a position to transfer the next lap.

In the present invention, the above-described operation is repeated each time a lap is formed, and each formed lap is transported and stored in an endless lap stocker selected from a plurality of lap stockers in sequence.
