As shown in FIG. 4, a rotating member 61 is spline-coupled to the rear of the shaft 58, and the rear end of the shaft 58 is connected to the rod of an air cylinder 63 by a rotatable joint 62. The positioning plates 59 are connected laterally to the forks 17 and operated by an air cylinder 65 to rotate the positioning plates 59 all at once from the forward position of the fork 17 to a lateral position that does not impede its forward movement.

Further, each fork 17 is provided with a detection rod 66 urged to a forward protruding position by a spring, and configured to operate a micro switch (not shown) or other known proximity detection signal generator when the detection rod 66 is pushed in. .

Next, in order to load the laminated plate 8 onto a container 69 such as a pallet 68 or a wooden box placed on a table 67 in front of the apparatus using the apparatus of the present invention, the following adjustments are first made.

The pallet 68 has a horizontal mounting surface and a vertical groove 70 provided on the surface into which the forks 17 are inserted.
The traveling body 18 is placed on a platform 67 in line with the path of the pallet 7, and has a front wall 71 at the front that tilts and supports the stacked laminated plates 8. The link 42 is adjusted horizontally and is moved by the air cylinder 53 so that the laminated plate 8 supported by the fork 17 and the roller 56 of the back-up rod 44 has a predetermined upright angle of 80 degrees, as will be described later. Adjust the upright angle.

Further, when using the container 69, since the container itself is tilted forward and placed on the mounting table 72, the mounting surface inside the container is also tilted. Therefore, the hydraulic cylinder 29 is used to tilt the traveling body 18 forward and downward so as to be parallel to the mounting surface, and at the same time, the air cylinder 53 is used to adjust the link 42 to the predetermined upright angle.

After the adjustment, the support base 12 is initially
The upper support surface of 5 is horizontal, and the back up rod 4
4 is lying down below the support surface (FIG. 1).

(1) When the laminated plate-like body 8 transferred by the conveyor 6 comes into contact with the stopper 16, the conveyor 6 stops, and the hydraulic cylinder 14 is shortened to rotate the support base 12, so that the laminated plate-like body 8 is almost The support stand 12 stops when it becomes vertical. This rotational stop causes the air cylinder 65 to operate and rotate the positioning plate 59 upward, and then the air cylinder 63 operates to move the positioning plate 59 backward and into contact with the front surface of the laminated plate body 1.

Next, the air cylinder 35 is shortened to raise the fork 17 along the cushioning material 60 of the positioning plate 59, and the laminated plate-like body 8 is transferred onto the fork 17 with its front surface aligned with the tip of the fork 17. At the same time, compressed air is injected into the bellows 40 to fix the longitudinal position of the fork 17.

Next, the air cylinder 48 is extended to rotate the backup rod 44 to a predetermined upright angle, and the rear surface of the laminated plate 8 is supported by the roller 56.

(2) When the above operation is completed, the air cylinders 63, 6
5 operates in reverse and moves the positioning plate 59 to the fork 17.
rotate out of the path of the Then hydraulic cylinder 3
1 extends to advance the traveling body 118, the fork 17 advances through the vertical groove 70, and the detection rod 6
6 reaches the unloading position where it hits the pallet front wall 71 or the laminated plates 8a already stacked on the pallet 68, the detection signal is generated and the traveling body 1
8 is stopped, and at the same time, the air cylinder 35 is operated in reverse to lower the fork 17, and the laminated plate 8 is
is transferred from the fork 17 onto the pallet 68. Then, the air cylinder 55 is extended, and the back-up lever 44 is tilted forward together with the link 42, so that the laminated plate-like body 8 is leaning against the front wall 71 or the laminated plate-like body 8a without any gap. Note that the support stand 12 returns to its original position while the traveling body 18 is moving forward.

(3) After the stacked plate-shaped body 8 has been propped up, the air cylinders 48 and 55 are shortened and the back-up rod 4
4 and link 42 to their original positions. Next, the traveling body 18 is moved backward by the hydraulic cylinder 31 to return the fork 17 to its original position, and the bellows 40 is vented to release the fork 17, which is returned to its original position by the spring 39.

Even when the container 69 is used, stacking is performed by the sequential operations (1) to (3). However, the mounting surface of the container 69 is also provided with a vertical groove 70a into which the fork 17 enters.

By repeating the operations (1) to (3) above, the laminated plate bodies 8 are successively stacked on the pallet 68 or container 69. A control device that repeatedly performs the above-mentioned sequential operations can be easily assembled with a well-known circuit configuration using ordinary devices such as limit switches and relays, so a detailed explanation thereof will be omitted.

The present invention has the above-mentioned configuration, and can stack the laminated plates on either pallets or containers, and can do so reliably, safely and quickly without creating gaps between the laminated plates due to the pressure of the back-up rod. It has the effect of allowing you to build up.

In addition, as a drive source in the present invention, in addition to a hydraulic cylinder and an air cylinder, various known actuators and electric motors can be used.
