In this embodiment, a protective cover 83 made of sheet metal for protecting the device from dust and the like is provided around the outer periphery of the entire device so as not to interfere with its operation.

The apparatus of this embodiment described in detail above operates as follows.

First, the origin waiting state is when the fluid pressure cylinder 19 is operated and the rod-shaped sliding member 7 is stopped in the state shown in FIG. 3, which is positioned on the right side.

First, the auxiliary fluid pressure cylinder 79 is actuated to drive the operating rod 71 to the right against the bullet 77, and the bell cranks 73 and 75 swing counterclockwise to move the stopper block 37 to the bullet 35. The horizontal base 2 was pushed down against the pressure and attached to the post 27.
9 is lowered and the roller 4 is attached to the drive member 43.
5 descends between the yoke-like protrusions 47, and the round bar 39,
The left and right guide blocks 31, 33, etc. are lowered as one unit. Therefore, the rod-shaped sliding member 7, material gripping portion 9, and vacuum cup 11 shown in FIG. 2 can be lowered to adsorb and hold the material.

Next, when the auxiliary fluid pressure cylinder 79 is released, the operating rod 71 moves to the left in FIG.

Next, when the fluid pressure cylinder 19 is actuated to extend the piston rod 51 to the left, the spring receiving plate 63 fixed to the piston rod 51 moves to the left and is biased to the left by the bullet 65. The protrusion 53 remains in contact with the locking member 61 fixed to the left end of the piston rod 51.
The shifter sliding member 49 moves to the left while maintaining the gap α shown in FIGS. 3 and 4.

The material is thus moved horizontally in the raised position. When approaching the end point of the material feeding action, the left base 21
The stopper 59 and the protrusion 57 of the shifter sliding member 49 come into contact with each other, and the leftward movement of the shifter sliding member 49 is prevented and stopped. Next, as the piston rod 51 continues to extend to the left, the locking member 61 at the left end of the piston rod 51 moves the shift pin 67 to the left, and the actuating rod 7 is moved through the link 69.
1 moves to the right against the projectile 77, rotates the two bell cranks 73 and 75 counterclockwise to push down the stopper block 37, and all related to the horizontal base 29 via the post 27. Lower the member.

Accordingly, the material is transported horizontally a required distance and then lowered vertically to the processing position of the press or onto the conveyor for delivery and released.

Next, when the operating direction of the fluid pressure cylinder 19 is reversed and the piston rod 51 is driven to contract, the locking member 6 at the left end of the piston rod 51 is first moved.
1 moves to the right, the shift pin 67 begins to move to the right due to the accumulated force of the ammunition 77, and the operating rod 71 simultaneously moves to the left, causing the bell cranks 73 and 75 to swing clockwise. Then, the stopper block 37 is raised by the ammunition 35,
The horizontal base 29 and all the members supported on the horizontal base rise.

Next, as the piston rod 51 moves rightward, the locking member 61 at the left end of the piston rod comes into contact with the left end wall of the rod hole of the shifter sliding member 49, causing the shifter sliding member 49 to move rightward.

Therefore, the yoke-like projection 4 of the shifter sliding member 49
The rolling wheels 45 and drive member 43, which are regulated by The plate material supply and transfer device returned to its standby state for the next operation.

As can be understood from the above description of this embodiment, in short, the present invention provides C in the press 5.

A first actuating device 19 for reciprocating movement is provided inside the machine frame 6, and a second actuating device 79 for moving the sliding member 39 up and down.
is provided in the machine frame 6, and each of the first and second actuating devices 1
9 and 79 are provided so as to be able to operate independently and separately.

As is clear from the above configuration, in the present invention, the first actuating device 19 for reciprocating the sliding member 39 provided with the material holding part 9 in the left-right direction and the first actuating device 19 for vertically moving the sliding member 39 Second actuator 79
are separately provided and independently and separately operable.

Therefore, according to the present invention, for example, only the first actuating device 19 is actuated to reciprocate the sliding member 39 only in the left-right direction, and only the second actuating device 79 is actuated to cause the sliding member 39 to slide. It is possible to move only the vertical movement of the sliding member 39, and by combining the operations of the first and second actuating devices 19 and 79, the horizontal movement and vertical movement of the sliding member 39 can be made in an appropriate trajectory. It is operable. In other words, by operating the first and second actuating devices 19 and 79, it is possible to move the sliding member 39 from side to side after it has been raised to the highest level, or to start movement from side to side before it has been raised to the highest level. This makes it possible to improve the efficiency of material supply.

Furthermore, since the first and second actuating devices are provided inside the machine frame 6, the overall configuration can be made more compact, and the problems of the prior art can be solved.
