so that the sequential operation continues until the cylinder is pushed out and returned to its original position, and then the hydraulic cylinders 14, 15, 16 of the lifting device 9 are pushed up and returned to its original position again. It is equipped with a known sequence circuit.

Next, the operation of the raw rubber plate cooling device will be explained.

Cooling water containing an anti-adhesive agent is placed in the water tank 2, and as shown in FIG. A predetermined number of receiving frames 1 are stacked diagonally on top of the support claws 11a and 13 in the unloading section 2B, and only the top two receiving frames 1 are stacked on the support claws 11b at the front of the upper stage. It is supported and placed horizontally.

In this state, the kneaded and rolled raw rubber plate is placed on the uppermost receiving frame 1 of the loading section 2A of the water tank 2, and the starting switch is turned on. Then, first, the fluid pressure cylinder 5 at the bottom performs an extrusion operation, and the extrusion frame 6
is horizontally moved to the left in FIG. 1, that is, to the carry-out section 2B, and only the lowermost receiving frame 1 placed on the extrusion frame 6 is horizontally moved to the left carry-out section 2B on the guide rail 7. At this time, the extrusion frame 6 is moved and the chain 4f is driven to simultaneously move the unloading section 2B.
A push tool 4d provided on the upper horizontal movement device 4 moves to the right together with the chain 4c, and this push tool 4d
, the uppermost receiving frame 1 of the carrying-out section 2B is horizontally moved to the uppermost section of the carrying-in section 2A.

Next, after the above fluid pressure cylinder 5 is pulled back, the three fluid pressure cylinders 11, 1 of the lifting device 9
4 and 15 each perform a push-up operation by a predetermined stroke. At this time, the rear lifting frame 9a
raises the support claw 9e at the lower end to a position slightly above the support claw 11a fixed to the column 10a, and similarly raises the support claw 9d at the upper end to a position slightly above the support claw 11b. frame 9b,
9c rises so as to lift the support claw 9f at its lower end to a position slightly above the support claw 13 fixed to the support column 10b. As a result, the receiving frame 1 on the lowermost guide rail 7 of the carry-out section 2B is lifted obliquely as shown in FIG. 1, and is supported by the support claw 11a on the left side and the support claw 13 on the right side. In addition, when the uppermost support frame 1 of the oblique stacking support frame 1 that has been supported on the support claws 11a and 13 becomes higher than the support claw 9d, it will be supported by the support claw 9d, but the rear lifting When the frame 9a rises, this support claw 9d also reaches a little above the support claw 11b fixed at the uppermost position, so that the uppermost receiving frame 1 is at a position where it is supported by the support claw 11b, that is, from the top of the carrying-out part 2B. Lifted up second.

On the other hand, when the pressing frame 6 for horizontal extrusion is pushed out to the forward end, the operating rod 8c of the support claw actuating device 8 is moved to the left, the upper support claw 8b retracts, and the lower support claw 8a protrudes. Loading section 2A
The lowest receiving frame 1 is lowered to the position of this support claw 8a. When the extrusion frame 6 returns to its original position, the operating rod 8c of the support claw actuating device 8 moves in the opposite direction again, causing the upper support claw 8b to protrude and the lower support claw 8a to retract. The receiving frame 1 is placed on the extruded frame 6, that is, on the guide rail 7, and all the receiving frames 1 above this are placed on the upper supporting claws 8.
Supported by b.

Each time such an operation is repeated, the lowest receiving frame 1 of the carrying-in section 2A moves to the carrying-out section 2B, and the highest receiving frame 1 of the carrying-out section 2B moves to the highest position of the carrying-in section 2A, so that each receiving frame 1 The raw rubber plate is gradually immersed in the cooling water in the water tank 1 by circulating the device power and placing the raw rubber plate on the receiving frame 1 at the top of the carry-in section 2A each time. When the above operation has been performed a predetermined number of times, the raw rubber plate is transferred to the unloading section 2.
It advances to B, where it is pulled up from the water tank 1 while being well drained in an inclined state, and reaches the top level. When the receiving frame 1 carrying the raw rubber plate moves horizontally in the cooling water, the front edge of the receiving frame pushes up the water and causes it to flow backward, thereby preventing the raw rubber plate from floating up. The raw rubber plates cooled in this way are taken out one by one from the top of the carry-out section 2B, and untreated raw rubber plates are placed on the empty receiving frame 1, allowing the cooling operation of a large number of raw rubber plates to be carried out efficiently. It is done.

As explained above, since the raw rubber plate cooling device of this invention is constructed as described above, the device can be significantly miniaturized compared to the conventional one, and requires only one operator and fewer man-hours. Cooling work of raw rubber plates can be carried out efficiently. Furthermore, since the structure of the device is small and relatively simple, it can be easily used even in small businesses that process rubber on a small scale. Furthermore, since it is small, it can be easily moved by attaching casters to the bottom of the device, allowing for effective use of space.
