Is cut and the product S is quickly separated from the material T to shorten the overall processing time.

[0013]

[Problems to be solved by the invention]

(1) Problems of the first prior art (FIG. 5). In FIG. 5, the unloader clamp 21 grips the end face of the product S because of its structure. For example, when the material T includes a plurality of small products S (FIG. 5), the small product S Can only be carried out while connected to

Therefore, after the small product S is carried out by the unloader clamp 21, it is necessary to separate the small product S from the material T in a separate step, and the processing efficiency is obviously reduced.

(2) Problems of the second prior art (FIG. 6). In the case of FIG. 6, if the position on the contour L where the product S is finally separated from the material T is on the side not gripped by the clamp 13 as shown in the figure (upper view in FIG. 6), the separation is performed. During processing, the material T is unstable, and the product S cannot be cut off with high accuracy.

The material T is moved by moving the carriage base 16 together with the side tables 11 and 18 in the Y-axis direction (lower view in FIG. 6) and moving the carriage 15 on the carriage base 16 in the X-axis direction. Is positioned at a predetermined position so that the position on the contour L where the product S is finally separated from the material T is on the side gripped by the clamp 13 (lower view in FIG. 6), and the material T is stabilized. .

However, if the product S is separated from the material T at such a position, the separated product S may enter the turret 14 (lower view in FIG. 6). Cannot be adsorbed, and the product S cannot be carried out.

(3) Problems of the third prior art (FIG. 7).

Further, in the case of FIG. 7, the installation of the sub-punch 19 increases the cost, and the take-out loader 30
It is not preferable to use in combination with the turret punch press 10 to which the sub-cylinder 19 is added in consideration of cost.

That is, the first prior art (FIG. 5) is a small product S
Requires a separate process to separate the two, and the third prior art (FIG. 7) is costly and is not preferred.

In this regard, the second prior art (FIG. 6)
Unlike the prior art (FIG. 5), even the small product S is attracted to the upper surface by the vacuum pad 31, so that the small product S
Can be carried out one by one, and a separate process for separating from the material T is not required. Unlike the third conventional technique (FIG. 7), the mold P, Since the product S is separated and carried out only with D, the cost does not increase.

However, according to the second prior art (FIG. 6), as described above, the product S separated from the material T
If the product S enters the inside (lower view of FIG. 6), the product S cannot be carried out.

The details of the takeout loader 30 used in the second prior art are as shown in FIG. 8, for example. A slider 33 which can travel along a guide rail 32 is provided with an upper and lower cylinder 38 and an upper and lower guide 39. The hanger 34 is attached via the intermediary.

The hanger 34 has a shaft 3
Vacuum pads 31 are attached via the respective vacuum pads 6, and each of the vacuum pads 31 is connected to a pneumatic device unit 35 by an air tube (air pipe) 37.

However, the overall height h (FIG. 8) of the hanger, which is the distance from the shaft 36 to the vacuum pad 31, is large, and the vacuum pad 31 is connected to the common pneumatic equipment unit 35 by one pipe 37. , The path of the pipe 37 is not compactly arranged, but is large as a whole.

Therefore, the conventional takeout loader 30
, The hanger 34 cannot enter the turret 14 (FIG. 6), and the product S (lower view in FIG. 6) in the turret 14 cannot be carried out.

An object of the present invention is such that when a product is cut off from a material using a mold in the turret in a turret punch press, the product can be taken out and taken out by entering the turret. Provide a product unloading device.

[0029]

According to the present invention, to solve the above-mentioned problems, as shown in FIGS.
