The arrangement relationship with the grip member 53 is shown. When the second gripper 5 rises in the above assembly, the plate material 7 introduced between the step surface 50b of the first guide 50 and the step surface 51b of the second guide 51 becomes the first clamp member 52 and the second clamp member 52. The clamp member 53 is clamped between the second guide 51 and the second clamp member 53, and the positional relationship between the second guide 51 and the second clamp member 53 is shown in FIG.

That is, in the state of FIG. 2, the strip portion 53a of the second clamp member 53 has the space 51e of the second guide 51.
Is located at the upstream end position of the
It is located in c '. From this state, the first gripper 4
When the second gripper 5 and the second gripper 5 are transferred in the plate material 7 transfer direction A, the second grip member 53 gradually moves in the plate material 7 transfer direction with respect to the second guide 51, and the second grip member 53 of FIG. Then, as shown in FIG. 4, the strip portion 53a becomes a space 51.
e to the downstream end and the sawtooth projection 53c is formed in the gap 51.
The state of being inserted into d'is completed and one transfer of the plate material 7 is completed.

As can be seen from FIGS. 2 to 4, the second grip member 53 is moved to the second guide 5 while the plate 7 is being transferred.
1 moves smoothly inside the plate 1, and the movement is not hindered by each part of the second guide 51, and at each time when the state of FIG. 2 shifts to the state of FIG. The lower surface of the portion not clamped by the grip members 52 and 53 is the upper surface 51 of the second guide 51.
