As shown in FIG. 3, the thin plate take-out portion 9 is held by a holding column 30 standing on the upper surface of the base 7, and an upper end surface of the holding column 30 with a horizontal axis through a holder 31. Further, a first air cylinder 32 is provided by extending the drive shaft 32a above the cylinder 14, and a circular thin plate suction portion 33 provided on the tip end surface of the drive shaft 32a of the first air cylinder 32. Consists of.

The circular thin plate suction portion 33 is formed by the drive shaft 3 described above.
L-shaped first provided with a vertical side fixed to the tip of 2a
And a second air cylinder 35 provided on the upper surface of the horizontal side of the first bracket 34 with the axis vertical and the drive shaft 35a extending downward from the lower surface of the horizontal side. The second air cylinder 35 includes a suction pad 37 as a suction means provided on the lower end of the drive shaft 35a via a second bracket 36.

As shown in FIG. 1, the second bracket 36 and the suction pad 37 are formed in such a size that they can enter the cylinder 14, and the suction pad 37 is not shown via a connecting pipe 38. It is connected to a vacuum device. The suction pad 37 can hold the circular thin plate 1 by suction by operating the vacuum device. Next, the operation of the take-out device 5 will be described.

First of all, the worker is a group of circular thin plates 1 ... Shown in FIG.
Is set in the cylinder 14. Then, the cylinder 14 is attached to the movable member 12 of the take-out device 5.

Next, as shown in FIG. 4, the take-out device 5 slides the movable member 12 to position the arbitrary cylinder 14 at a position facing the thin plate take-out portion 9. The push-up means 15 uses the circular thin plate group 1 based on the detection signals of the first and second sensors 26 and 27.
The circular thin plate group 1 is pushed up so that the uppermost surface of the ... reaches the height (A surface) of the first sensor 26, and is held at that height. Further, this operation is performed every time the height of the uppermost surface of the circular thin plate group 1 becomes less than the B surface.

Then, the take-out device 5 operates the first air cylinder 32 to position the suction pad 37 above the cylinder 14 so as to face it. Then, the second air cylinder 35 is operated to operate the suction pad 37.
Is inserted into the cylinder 14, and a vacuum device (not shown) is operated to suck and hold the top circular thin plate 1 of the circular thin plate group 1.

Next, the take-out device 5 drives the suction pad 37 to move upward to take out the suction-held circular thin plate 1 from the inside of the cylinder 14 through the passage 24a and upward. Then, the first air cylinder 32 is driven in the extending direction, the circular thin plate 1 is positioned on the working surface 2a of the press device 2 so as to face it, and is placed on the upper surface of the working surface 2a. Next, the operation when two or more circular thin plates 1 are stuck together will be described with reference to FIG.

In the state where the circular thin plates 1 are stacked and held, as described in the section of the conventional example, two or more sheets may be stuck to each other in a vacuum contact state. in this case,
As shown in FIG.
The circular thin plates 1 ... Are adsorbed and held.

Next, the suction pad 37 is driven upward while holding the two circular thin plates 1 and 1. As a result, the peripheral edge of the circular thin plate 1 successively contacts the tops of the saw blade-shaped projections 25 formed in the passage 24a, and rises while being caught.

As a result, the circular thin plate 1 is repeatedly bent and restored to its original state. By such an operation, a gap is created between the two circular thin plates 1 and 1 that are stuck together, and these are separated. Such separation usually occurs at the third to fourth projections from the lower end of the projection 25, and the circular thin plate 1 stuck to the lower side from this height separates and is shown by a two-dot chain line in FIG. Thus, it falls into the cylinder 14 from the passage 24a. As a result, the take-out device 5 can take out the circular thin plates 1 one by one from the circular thin plate group 1.

According to such a structure, even if the circular thin plates 1 ...
The work efficiency can be improved by separating the sheets one by one without the operator's hand, and the product yield can be improved because the two sheets are not accidentally conveyed to the press device 6 in a state of being stuck to each other. improves.

Further, since it is not necessary to detect whether or not two or more sheets are stuck to each other by the sensor, the structure can be simplified accordingly. Further, even in the case of the celluloid circular thin plate 1 that cannot be detected by such a sensor, it is effective because the individual thin plates can be effectively separated.

On the other hand, the height difference h between the surface to be separated (the third to fourth protrusions from the bottom of the protrusion 25) and the surface B is adjusted to be smaller than the outer diameter d of the circular thin plate. Therefore, the separated circular thin plate 1 is prevented from being turned upside down to the back side, and it is not accidentally pressed in a state of being turned upside down. It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified without changing the gist of the invention.

For example, the protrusion 25 is formed in the passage 24.
Although it was provided in four places on the inner wall surface of a, it may be two or three places, or five or more places,
Further, it may be a short projection instead of the saw-tooth shape.

Further, the use of the circular thin plate 1 was a diaphragm in the above-mentioned embodiment, but it is not limited to this. That is, this take-out device 5 can be applied in any process as long as it is a step of taking out from the stacked state the two thin plate members 1 ... Which may stick to each other for whatever purpose.

Further, in the above-described embodiment, the suction pad 37 holding the circular thin plate 1 by suction is the separator 24.
Although it only rises in the passage 24a, it may be moved up and down in the passage 24a to ensure the separation.
