From the state where 4'corresponds to the bottom of the mobile storage rack F,
When the one-step base frames 14 and 14 'are moved up, the carrier B and the carrier E rotate about the shaft 2 by a predetermined angle. For this reason,
The shaft 3 at the other end of the transfer device B (similarly to the transfer device E) draws an arc around the shaft 2, and the shaft 3 is the attachment end of the string belt b of the transfer device B and the string belt 45 on the base frame 14. The base frame
Since the cord-shaped belt 45 on 14 can slide back and forth on the base frame 14 by the U-shaped sliding frame 15, it can be moved to the shaft 2 side via the shaft 3.

In this way, when the base frames 14 and 14 'are raised, the cord-shaped belt 45 is sequentially moved to the rotation center shaft 2 side via the U-shaped sliding frame 15, and the base frames 14 and 14' are moved. At the time of descending, the string belt 45 is sequentially moved through the U-shaped sliding frame 15 in the direction away from the rotation center shaft 2, regardless of whether the base frames 14 and 14 'are moved up and down.
The transfer devices B and E are rotated so that the transfer of the molded product can be performed without any trouble.

Further, even if the cord-shaped belt 45 slides back and forth on the base frames 14 and 14 ', the cord-shaped belt provided orthogonal to the cord-shaped belt 45.
In 50, it is necessary to carry the molded product into the moving storage rack F at a predetermined position on the base frames 14 and 14 ', or to carry the molded product out of the moving storage rack F. Therefore, at the position of the string belt 50, Corresponding cord-shaped belt 45 is a guide roller 51, 52, 52, which is directly fixed to the base frame 14.
A concave portion is formed by 53, and the position of the string belt 50 is held at a predetermined position regardless of the sliding of the string belt 45.

The molded product that has been cured and pushed out of the mobile storage rack F is
On the base frame 14 'of the carry-out station D, the cord-shaped belt 5
The cord-shaped belt 45 ′ driven in the direction of the conveying device E from 0 ′ is placed on the cord-shaped belt b of the conveying device E and sent to the molded product takeout part G.

In the molded product take-out section G, the molded product on the pallet is pulled up by the vacuum suction means and taken out on the adjacent molded product accompaniment path 74 'by the action of the air cylinder. on the other hand,
The pallet collides with a stop member 77 provided at the end of the transport path 74, and a machine frame provided with cord belts 79, 79 of the transport device H that sends the pallet to the compression molding machine A side by operating a switch. The pallet is lifted, and is placed on the cord belts 79, 79 of the conveyance device H from the cord belt on the conveyance path 74 and sent to the compression molding machine A side.
