Accordingly, the movable plate 124 and the fixed piece 123 of the finger portion 122 are close to each other, while the forming plate 20 is separated from the finger portion 122 by the elastic biasing force of the elastic member 126. Can be gripped with minimal force without deformation.

Through the above process, the forming plate 20 is transported to the loading unit by the lifting means 140 and the horizontal movement means 150 in a gripped state. Molding plate 20 transferred as described above is released from the holding means 120 in the loading portion, for this purpose, to turn on the operation of the cylinder 134 provided in the drive means (130). Accordingly, the cylinder rod 136 is extended, and the movable pieces 124 sequentially connected through the cylinder rod 136, the movable beam 133, the connecting member 132, and the moving member 131 are eventually connected. The cylinder rod 136 is moved in the extending direction. That is, each of the movable pieces 124 is moved in the direction opposite to the direction in which the elastic force of the elastic member 126 is biased toward the stationary piece 123 disposed with the elastic member 126 therebetween, and thus, the ping As the space between the movable piece 124 and the stationary piece 123 of the rejection 122 is separated, each forming plate 20 can be cancelled. By going through the above process, the forming plates 20 released from the finger portions 122 of the gripping means 120 can be loaded on the loading portion.
