In this state, the upper parts of the carts 20 and 21 are inclined tables 57 and 58, so the guide claws 2 at the front
It will stop in the state where it is in contact with 2 and 23.
Therefore, by extending the cylinders attached to the bases on both sides of the rails 18 and 19, the operating rod 67
is pushed and moved, the front stopper 65 comes into contact with the pressing ring 61 of the guide pawls 22, 23, and the rear stopper 66 comes into contact with the guide tube 64, moving the carts 20, 21 along the rails 18, 19. We will move forward. It is assumed here that the cylinders are provided with synchronized valves and their movements are completely synchronized.

When the cylinder is further contracted in this state, the stopper 65 comes into contact with the guide cylinder 64, and the carriages 20, 21, which are integrated with the guide cylinder 64, move backward. Here, the guide claws 22 and 23 that are rotatably attached to the front ends of the carts 20 and 21 are in a state where the guide rollers 71 attached to the guide claws 22 and 23 are in contact with the front ends of the rails 18 and 19. By retreating, the guide claws 22 and 23 stand up, and in this state they move to the rear of the rails 18 and 19.
