38b is provided to regulate the position of the plate material P when clamped on the fixed clamp member 32 to a fixed position.
That is, these position restriction stoppers 38a, 38b are movable back and forth between a restriction position corresponding to the front end of the fixed clamp member 32 with a predetermined positional relationship and a retracted position rearward of this position restriction position. It is installed. Therefore, the position restricting stoppers 38a and 38b are composed of members extending in the vertical direction, which are set in parallel with each other.
It is swingably connected to the mounting frame 24 via a plurality of pairs of connecting arms 40a, 40b which are vertically separated from each other.

Here, the mounting frame 24 has a hollow inside, and each pair of connecting arms 40a, 40a.
b are connected via a connecting shaft 42 so as to rotate integrally with each other. A slit 24a extending in the vertical direction is formed in the rear end surface of the mounting frame 24 in a state of penetrating in the thickness direction.
A swing arm 44 for swing-driving the connecting arms 40a, 40b is taken into the mounting frame 24 via the, and is fixed to the central portion of the connecting shaft 42. The rear end of the swing arm 44 is taken out behind the movable frame 26 through the slit opening 26a of the movable frame 26.

In order to swing and drive the swing arm 44, a third hydraulic cylinder 48 is attached to the upper portion 24a of the attachment frame 24 in a suspended state via an attachment stay 46. Hydraulic cylinder 48
The lower end of the piston rod 50 is rotatably connected to the rear end of the swing arm 44 located at the uppermost position. With such a configuration, the hydraulic cylinder 48 is connected to the piston rod 5

In the plate material transfer device 10 configured as described above, the plate material P is taken out from the storage shelf 12 and inserted into the predetermined processing space 18 of the hot press device 14 from the side (right side in the drawing). 3 to FIG.
Will be described with reference to. It should be noted that, in FIGS. 3 to 7, for the sake of clarity of explanation, only one plate P and one mounting shelf 12 for mounting it or one processing space 18 into which it is inserted are drawn. However, as is clear from the above description, many of them are arranged in the vertical direction.

First, when an instruction to start the transfer operation of the plate P from the storage rack 12 to the hot press device 14 is issued from a control unit (not shown), the first hydraulic cylinder 28 is activated and the mounting frame 24 is moved forward. Move it to the left in the figure. As a result, as shown in FIG. 3, the fixed clamp member 32 fixed to the mounting frame 24 is attached to the storage shelf 1.

Push down. As a result, the plate material P is clamped (clamped) by the fixed clamp member 32 and the movable clamp members 34a and 34b at the rear end thereof, and is brought into a state of being integrated with the plate material transfer device 10.

Next, the third hydraulic cylinder 48 is activated to push down and drive the piston rod 50. As a result, the swing arm 44 rotates clockwise in the drawing, and accordingly,
The uppermost connecting arms 40a and 40b integrally connected to the swing arm 44 also rotate clockwise in the drawing. As a result, the position regulating stoppers 38a, 3 rotatably connected to the uppermost connecting arms 40a, 40b, respectively.
As shown in FIG. 5, 8b is pulled into the standby position behind the regulation position.

Then, the above-mentioned first hydraulic cylinder 28
By continuing to drive, the plate material P integrated with the fixed clamp members 32 and the movable clamp members 34a and 34b of the upper and lower pairs is pushed forward from the storage rack 12 (left in the drawing), and the corresponding action is taken. The rear end is clamped by only the fixed clamp member 34 and the movable clamp members 34a and 34b. After that, by further continuing the drive of the first hydraulic cylinder 28, the plate material P clamped by the plate material transfer device 10 is
It will be inserted into the corresponding processing space 18 from the side (right in the figure).

Here, as described above, the total thickness of the front end portion of the fixed clamp member 32, the movable clamp, and the plate material P at the clamp position is determined by the distance between the pair of upper and lower heat plates 20 in the processing space 18. The distance is set to be smaller than the gap height. As a result, the insertion operation of the plate material P is not interrupted at all, and the insertion operation is continued until the plate material P is completely housed in the corresponding processing space 18, as shown in FIG. .

After that, the second hydraulic cylinder 30 is activated in the reverse direction to pull up the movable frame 26 to release the pressing force of the movable clamp members 34a and 34b, and as a result, the plate material P is fixed. The clamped state by the clamp member 34 and the movable clamp members 34a and 34b is released. As a result, the plate material P is placed on the lower hot plate 20 except at least the portion supported on the front end portion of the fixed clamp member 32. Then, by activating the first hydraulic cylinder 28 in the reverse direction and retracting the mounting frame 24 rearward, the front end portion of the fixed clamp member 32 is pulled out from the lower surface of the rear end portion of the plate material P, and this plate material The P is placed entirely on the lower heating plate 20. Further, by further driving the first hydraulic cylinder 28 in the reverse direction, the fixed clamp member 3
2 and the movable clamp members 34a and 34b are the processing space 1
8 is pulled out backward, and thus the hot pressing operation on the plate material P becomes possible.

As described above in detail, in this embodiment, the total thickness of the front end portion of the fixed clamp member 32, the movable clamp, and the plate material P at the clamp position is the same as the above-mentioned pair of upper and lower working spaces 18. The separation distance of the heat plate 20, that is,
It is set smaller than the gap height. As a result, the inserting operation of the plate material P is continued without any interruption until the plate material P is completely housed in the corresponding processing space 18. As a result, the working time is surely shortened and the working efficiency is improved as compared with the case of using the conventional pusher member for the plate.

The present invention is not limited to the configuration of the above-described embodiment, but can be variously modified without departing from the gist of the present invention.

For example, in the above-described embodiment, the plate material transfer device 10 is described as being configured to insert the plate material P into the processing space 18 of the hot press device 14, but the present invention is not limited to this. Without being limited to such a configuration,
Any material can be applied as long as the plate material P is inserted laterally into the processing space.
