[0013]

Next, the operation of the device of the present invention will be described. First, the side mold 3 in which the bottom plate 4 is housed in advance by the method described below.
The raw material is supplied from the hopper to the inside of the container, and press molding is performed by the upper mold 1. When the side mold 3 is also lifted by a mechanism (not shown) after the upper mold 1 is lifted, the bottom plate 4 and the compact W placed on the bottom plate 4 are left on the lower mold 2.

In this state, the take-out head 20 of the transfer device 15 descends from the side of the lower mold 2 and enters toward the lower mold 2. At this time, the chuck bar 23 of the take-out head 20 is in the open position, and the frame 2 of the take-out head 20 is
1 enters a position lower than the upper surface of the lower mold 2 and rises vertically. In this way, while the take-out head 20 moves up, the chuck bar 23 chucks the lower mold 2 from both sides and lifts the bottom plate 4 and the compact W. In this way, the lifting cylinder 21 is raised while raising the entire take-out head 20.
The bottom plate 4 and the molded body W are relatively raised by a toward the receiving plate 29 that is horizontally supported by the receiving plate support tool 28 at the upper position, and the receiving plate 29 hits the upper surface of the molded body W. Be able to push up. When the upper and lower cylinders 24 are operated in this state to slightly lower the pressing tool 27 with the spring 26, the receiving plate 29 comes into close contact with the upper surface of the molded body W at a predetermined pressure. At the same time, the take-out head 20 rises to a position above the lower mold 2.

The take-out head 20 chucking the bottom plate 4 and the compact W moves horizontally from this state onto the conveyor 14, and the take-out head 20 is moved around the bearing 18 by 18
Rotate 0 °. As a result, the molded body W is turned upside down and is placed on the receiving plate 29, so that the take-out head 20 is lowered and the receiving plate 29 is placed on the conveyor 14. In this way, the compact W having low strength can be taken out onto the conveyor 14 without losing its shape.

Thus, when the molded body W is placed on the conveyor 14 together with the receiving plate 29, the chuck bar 23 keeps chucking the bottom plate 4. Therefore, the take-out head 20 is turned upside down again in the route opposite to the above,
With the bottom plate 4 chucked, it returns to the top of the lifting device 11.
Then, the elevating plate 13 rises to move the frame 2 of the take-out head 20.
Enter into 1 and receive the bottom plate 4. When the chuck bar 23 of the take-out head 20 is opened in this state, the bottom plate 4 is placed on the elevating plate 13.

At this time, the returning device 5 is located immediately above the elevating device 11 as shown by the solid line in FIG. 1, and the bottom plate 4 that has been lowered on the elevating plate 13 is the chuck bar 1 of the returning device 5.
Chuck by 0. After the elevating plate 13 is completely lowered, the returning device 5 moves horizontally, and the U-shaped arms 7 enter both sides of the lower mold 2 of the molding machine as shown by an imaginary line in FIG. When the elevating cylinder 8 is lowered slightly in this state, the bottom plate 4 is placed on the upper surface of the lower mold 2. After the bottom plate 4 is returned in this way, the side mold 3 that has been raised descends toward the lower mold 2, and the bottom plate 4 is stored inside the side mold 3 again. During this time, a new receiving plate 29 is supplied onto the receiving plate support 28 of the take-out head 20 to complete one cycle.

When the return device 5 receives the bottom plate 4 from the take-out head 20, the brushing head 30 shown in FIG. 2 can be moved by the cylinder 31 to brush the upper surface of the bottom plate 4. By doing so, the surface of the bottom plate 4 can be always cleaned and then returned to the molding machine. The above description was made following the movement of the specific bottom plate 4, but in reality, when the take-out head 20 moves above the lower mold 2, the return device 5 immediately advances in the direction of the lower mold 2 and moves the bottom plate 4 into the lower mold. It is designed to supply to the upper two.
Then, when the take-out head 20 is located directly above the conveyor 14, the next press molding is performed.
