DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work transfer device, and more particularly to a work transfer device for preventing a product adsorbed from drooping in a lateral direction due to its own weight.

[0002]

2. Description of the Related Art Conventionally, a work transfer device that takes out a product processed by a plate processing machine such as a turret punch press and conveys the product in the air has a stretch 1 shown in FIG.
It has 0.

[0003] This stretch 10, as shown in the figure,
The product pallet 3 is provided with a suction pad 11, sucks the product S processed by the suction pad 11, conveys the product S in the longitudinal direction (X-axis direction), and transfers the product S to the work discharge means 3 (FIG. 1).
01.

In this case, the stretch 10 is formed longer in the X-axis direction and shorter in the Y-axis direction (FIG. 6).

[0005] Accordingly, when the workpiece movement positioning device such as the clamp 100 (FIG. 1) holding the product S immediately after processing is a tool (for example, a turret punch press, the punch P
(FIG. 1) and a die composed of a die D, and a suction pad 11 in which the stretch 10 shown in FIG. The product S can be surely adsorbed.

When the product 10 is returned to the work unloading means 3 (FIG. 1) in a state where the product S is sucked by the suction pad 11 disposed long in the X-axis direction, the product S is transferred to the product pallet 301 (FIG. 1). 1) On the upper side, it can be carried out and accumulated at an arbitrary position in the X-axis direction.

[0007]

However, when the product S to which the stretch 10 (FIG. 6) is adsorbed is a thin sheet product having a thickness of, for example, about 0.6 mm, the sheet S is stretched in the Y-axis direction. The product S may drop.

That is, as shown in FIG. 6A, when the distance A from the center line L in the X-axis direction of the stretch 10 to the end of the sheet-like product S is large, the stretch 10 becomes short in the Y-axis direction. Therefore, only the suction pads 11 arranged in two rows on both sides of the center line L as shown in FIG.
The whole sheet-shaped product S cannot be adsorbed.

Therefore, in the conventional work transfer device, the sheet-like product S is held by the suction pad 11 of the stretch 10.
When the sheet is sucked, the sheet-like product S hangs down in the Y-axis direction.

As a result, while the sheet-shaped product S hanging in the Y-axis direction is being transported in the air, adverse effects such as bending of the sheet-shaped product S occur, and the value of the product is lost.

Further, as shown in FIG.
Also, when the sheet-shaped product S separated from the above is sucked and taken out by the suction pad 11 of the conventional stretch 10, the sheet-shaped product S hangs down in the Y-axis direction as described above.

For this reason, the hanging portion of the sheet-like product S is caught by the separating portion 13 of the base material 12 (reference numeral B), and cannot be taken out smoothly while being sucked by the suction pad 11.

As described above, conventionally, the stretch 10 is X
Since it is formed long in the axial direction and short in the Y-axis direction (FIG. 6), when a sheet-shaped product S having a large dimension in the Y-axis direction is sucked, the sheet-shaped product S hangs down in the Y-axis direction, When removing the sheet-like product S from the base material 12,
The sheet-shaped product S cannot be transported smoothly because it is caught on the base material 12, and when the sheet-shaped product S is transported in the air, it breaks down and loses its value as a product.

An object of the present invention is to prevent a product from being taken down from a base material by preventing the product from being pulled down in the horizontal direction due to its own weight, and to eliminate the buckling during aerial conveyance, thereby improving the processing efficiency of the workpiece. Provided is a work transfer device that is improved.

[0015]

According to the present invention, as shown in FIGS. 1 to 5, according to the present invention, a loader 302 for moving between a plate processing machine 1 and a product pallet 301 is provided.
Suction means 30 for sucking a work on the stretch 304
There is provided a work transfer apparatus characterized in that a plurality of the suction means 308 and 309 are provided, and some of the suction means 308 are mounted so as to be able to rise in the longitudinal direction more than the remaining suction means 309.

Therefore, according to the structure of the present invention, the processed product S is attached to the lifting plate 305 by operating, for example, the lifting cylinder 311 while the processed product S is being sucked by the suction means 308 and 309 (FIG. 5A). By raising only the sucking means 308 in the longitudinal direction (FIG. 5 (B)), the product S can be temporarily deformed in the longitudinal direction. Sagging is prevented (FIG. 5B).

For this reason, the suction means 308, 30 of the present invention is used.
9, the product S temporarily deformed along the longitudinal direction (FIG. 5)
(B)) In addition to being able to be smoothly taken out of the base material, breakage of the hips during air conveyance is eliminated, and the processing efficiency of the work is improved.

(B)), the remaining 18 suction pads 309 are fixed to the stretch 304.

The operation of the present invention having the above configuration will be described below.

(1) Operation from loading of material T to processing. When one material T is picked up by the suction pad 202 of the work loading means 2 (FIG. 1) and loaded into the turret punch press 1, the material T gripped by the clamp 100 is positioned at the processing position, and the ram striker 105 punches the material T. When P is beaten, punching such as punching is performed on the material T by cooperation of the punch P and the die D.

(2) Suction operation of the sheet-like product S. When the processing is completed, the stretch 304 of the work transfer device according to the present invention, which has been waiting near the processing position, (see FIG. 5).
(A)), it descends by the cooperation of the vertical cylinder 306 and the vertical guide 307, and sucks the processed sheet-like product S by the suction pads 308 and 309.

At this time, the sheet-shaped product S has a large dimension in the Y-axis direction and hangs down in the Y-axis direction (FIG. 5).
(A)).

Then, as shown in FIG. 5B, when the lifting cylinder 311 is actuated, the piston rod 312 is pushed out and pushes the contact portion 314A, whereby the lifting plate 305 is pivoted on the shaft 310 as a fulcrum. Turn upward.

As a result, the bellows-shaped suction pad 308 attached to the lifting plate 305 rises in the longitudinal direction (X-axis direction) above the suction pad 309 fixed to the other stretch 304.

As a result, the sheet-shaped product S is temporarily deformed in the longitudinal direction, and the sagging in the horizontal direction due to the weight of the product is eliminated (FIG. 5B).

Thereafter, by operating the upper and lower cylinders 306 again, the stretch 304 is raised, and the sheet-like product S is taken out from the base material 12 (FIG. 6B).
In this case, since the sheet-like product S is temporarily deformed along the longitudinal direction, it can be smoothly taken out from the base material.

(3) Unloading operation of the sheet-like product S. In a state where the sheet-shaped product S temporarily deformed along the longitudinal direction is sucked by the suction pads 308 and 309 (FIG. 5B),
When the driving motor 302B (FIG. 3) built in the loader 302 is rotated, the loader 302
The vehicle travels along the direction 00 and travels toward the work unloading means 3.

In this case, as described above, the suction pad 3
09 and the bellows-like suction pad 30 raised above
The sheet-like product S adsorbed on 8 is temporarily deformed along the longitudinal direction (FIG. 5B), so that it does not break while being transported in the air, and retains its value as a product.

When the loader 302 reaches the position above the product pallet 301 of the work unloading means 3 (FIG. 1), the upper and lower cylinders 306 are operated again to lower the stretch 304.

As a result, when the sheet-like product S is released from the suction pads 308 and 309, the temporary deformation state (FIG. 5 (B)) along the longitudinal direction is also released and returns to the original flat state, and the product already exists. It can be placed on the flat sheet-like product S accumulated on the pallet 301.

In this embodiment, the case where the suction means 308 on the side remote from the turret punch press 1 (FIG. 1) is attached to the lifting plate 305 is described in detail. However, the present invention is not limited to this, and the present invention is not limited to this. The same effect is obtained when the suction means 309 on the side close to the punch press 1 is attached to the lifting plate 305.

In this embodiment, the case where the present invention is applied to a turret punch press has been described in detail. However, the present invention is not limited to this, and may be applied to other plate processing machines such as a laser processing machine. Of course, the same effect can be obtained.
