And a moving unit 50 for moving to 80 (see FIG. 7).

When the metal panel required for the blocking process is supplied from the coil material supply unit 2, the coil material is stretched into a panel shape while passing through the leveler 4, and a blanking process is performed while passing through the mold part 6 where continuous work is performed. You lose.

The intermediate material discharged from the mold part 6 due to the blanking process is moved along the supply part 8 to be supplied to the reverse part 10, and the upper and lower surfaces of the intermediate material change while passing through the reverse part 10. The work is in progress.

The reversing operation is a task for converting the intermediate material in the direction required in the next process. When the intermediate material is not supplied with the reversing operation, the reversing part 10 is moved to maintain a distance from the line where the intermediate material moves.

The intermediate material that has passed through the reversal part 10 is laminated on the temporary pallet 31, and when the intermediate material is laminated by the set number, the intermediate material laminated on the temporary pallet 31 by the driving unit 50 is driven. The transfer pallet 80 is moved.

Therefore, the intermediate materials stacked on the transfer pallet 80 are moved to the next process, and the intermediate materials stacked in the direction required by the process are supplied one by one.

Figure 4 is a perspective view of the reverse portion of the intermediate material transfer apparatus according to an embodiment of the present invention, Figure 5 is an operating state diagram showing the reverse portion of the intermediate material transfer apparatus according to an embodiment of the present invention.

3 to 5, the reversal unit 10 is mounted on the belt conveyor 11 for transferring the intermediate material moved by the supply unit 8, and the intermediate material moving along the belt conveyor 11. After the conversion of the mounting portion 12 for seating the intermediate material on the belt conveyor 11, the reverse drive unit 13 for moving the mounting portion 12 to the belt conveyor 11 side, and inputs the information of the intermediate material The operation unit 14 (see FIG. 12) and the control unit 15 (see FIG. 12) for transmitting an operation signal to the reverse drive unit in accordance with data input from the operation unit 14.

If the operator inputs data of the intermediate material produced by the blanking process through the operation unit 14 before the blanking process is started, the controller 15 determines whether the reverse operation is necessary.

At this time, the tongs 55 may be caught on the bottom surface of the intermediate material laminated on the temporary pallet 31, so that the plurality of stacked intermediate materials can be easily raised.

In addition, since the plurality of passing grooves 31b are formed in the protruding rail 31a, when the tongs 55 are moved in a direction orthogonal to the protruding rails 31a, the ends of the tongs 55 pass through the through holes 31b. Since it is inserted into the bottom of the intermediate material through the lower end of the tongs 55 can be caught on the bottom of the intermediate material.

Since the pressing panel 37 is formed with a pressing protrusion 37a for pressing the side surface of the intermediate material through the passage groove portion 31b, the pressing protrusion 37a is disposed at a lower side than the intermediate material disposed at the bottom of the stacked intermediate materials. Therefore, the intermediate material disposed at the bottom can also be easily pressed to align.

The elevating part 32 is rotatably installed on the main body 33 and has a support rod 34 having a thread formed on its circumferential surface. The lifting unit 32 is installed to be elevated along the main body 33, and the support rod 34 penetrates.
