Repeat withdrawal.

When the forklift 14 is positioned at a position that is just right with respect to the material pallet 11, the lifter 16 on which the material T as the packing material is moved up and down, and the forklift 14 is moved to the material pallet. The material T is abutted against the reference pin 12 while approaching and separating from the reference pin 11 again.

However, it is difficult for the worker 15 to obstruct the front view due to being blocked by the lifter 16 which moves up and down and the material T thereon, so that it is difficult to strike the material T against the reference pin 12. is there.

As a result, it is apparent that the time for loading the material T on the material pallet 11 is delayed, and it takes a long time to carry the material T into the plate material processing machine 10 (FIG. 7), and the carrying efficiency is obviously reduced. .

It is an object of the present invention to provide a material loading apparatus in which a material is aligned with a reference line during loading of the material into a plate material processing machine, thereby eliminating a material loading reference pin and simplifying the material loading operation. provide.

(F) shows exactly the same operation on the left and right sides, but FIG. 6 (E) shows different operations on the left and right sides for convenience of explanation.

(1) Descent of the vacuum hanger 4 (FIG. 6)
(A) left figure).

First, as shown in the left diagram of FIG. 6A, the vertical cylinder 402 is operated to lower the entire vacuum hanger 4.

In this case, the moving table 2 is on standby on the loading clamp 3 side (the left diagram in FIG. 6A).

The loading clamp 3 is waiting behind the moving table 2 (the right figure in FIG. 6A). In this state, the blank T is loaded with one blank T taken from the vacuum hanger 4 side. The operation is continued until the moving table 2 returns to the loading clamp 3 side (left diagram in FIG. 6D) (right diagrams in FIGS. 6A to 6D).

(2) One sheet of material T and moving table 2
To the vacuum hanger 4 side (the left figure in FIG. 6B).

Next, as shown in the left diagram of FIG. 6B, after one material T is taken out through the vacuum hanger 4, the vacuum hanger 4 is raised by operating the upper / lower cylinder 402. Then, the moving table 2 is moved from the loading clamp 3 side, and is stopped below the one-piece material T.

Then, before taking one sheet of the material T, the vacuum pads 403A and 404A of the vacuum hanger X403 and the vacuum hanger Y404 are previously stroked, for example, by 200 mm as shown in FIG. And TY are detected by the end face detection sensors S1 and S2, so that one sheet separating device (for example, a magnet floater or the like) hits the end faces TX and TY of the material T, and the uppermost material T is separated.

(3) Placing the material T on the moving table 2 (left diagram in FIG. 6C).

Next, as shown in the left diagram of FIG.
The single material T is released and placed on the moving table 2 from the vacuum hanger 4.

(4) The moving table 2 is returned to the loading clamp 3 side (the left figure in FIG. 6D).

Next, as shown in the left diagram of FIG. 6 (D), the moving table 2 on which the blank T is taken is moved and returned from the vacuum hanger 4 side to the loading clamp 3 side.

(5) Align the material T with the reference line (FIG. 6)
(E) on the left, and (E) on the right).

After returning the moving table 2 on which the blank T is taken to the loading clamp 3 side (FIG. 6).
As shown in the left diagram of FIG. 6D and the left diagram of FIG. 6E, the reference cylinder 5 is lowered by operating the upper and lower cylinders 502.

Then, the moving table 2 is lowered and moved toward the reference stopper 5, whereby the material T thereon is brought into contact with the reference stopper 5.

Thus, the end face of the material T can be aligned with the reference line in the Y-axis direction.

Next, as shown in the right diagram of FIG. 6E, the loading clamp 3 is moved, and when the end face detection sensor S3 detects the end face of the material T, the loading clamp 3 is temporarily stopped. Then, the material T on the moving table 2 is gripped.

Thus, the end face of the material T can be aligned with the reference line in the X-axis direction.

(6) Loading of the material T (FIG. 6 (F)).

Finally, the material T is carried into the turret punch press 1 by further advancing the loading clamp 3 while holding the material T aligned with the reference line with the loading clamp 3 (FIG. 6 (F)). ).

[0068]

As described above, according to the present invention, by providing the reference stopper between the loading clamp and the vacuum hanger, the material loaded on the material pallet on the vacuum hanger side can be processed by the plate material via the loading clamp. This material can be aligned with the reference line by this reference stopper while being loaded into the machine, and there is no need to hit the reference pin when loading the material.
There is an effect that the reference pin for loading the material is eliminated and the loading operation of the material is simplified.

Further, by providing the moving table,
While the previous material is being processed by the plate material processing machine, the next material can be received by this moving table and aligned with the reference line, so that it can stand by reliably, compared to the case where the next material is received by the vacuum pad and waiting There is also an effect that there is no fear that the material will fall due to vacuum leakage.
