DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a suction cup according to the present invention is shown in FIGS.
Explained by.

Reference numeral 1 designates a suction plate made of a hollow disk body, the lower surface of which is a suction surface 2 having a convex curved surface in one direction, and a large number of suction holes 3 are provided on the entire surface thereof.

The suction plate 1 is attached to a lower end of a piston rod 6 of an air cylinder mechanism 5 attached to a movable member 4 so that the suction plate 1 can be moved up and down at any time. The suction surface 2 is made to communicate with the suction source, and by its downward movement, the suction surface 2 is closely opposed to the upper surface of the plate material stack A to suck and peel off the uppermost plate material a, and then the suction plate 1 is moved upward, and then the movable member 4 is moved.
Was moved in the direction of the arrow shown in FIG. 1B to take out the peeled plate material a.

In the peeling operation by the downward movement of the suction cup 1 in the above embodiment, the convex curved suction surface 2 on the lower surface is brought into contact with the middle portion of the middle height of the suction surface 2, or a small interval without contacting the plate surface a. However, since both ends of the suction surface 2 having a convex curved surface form a large gap between the surface a and the plate material a due to the convex curved surface shape, in this embodiment, Attach elastic material 8 such as rubber to the entire periphery,
The lower end of the entire circumference is projected from the lower surface of the suction plate 1, and the lower edge of the elastic member 8 is brought into contact with the surface a of the plate material as shown in FIG.
As shown in, the entire circumference of the space 9 between the suction surface 2 and the plate a is sealed.

In the above-mentioned state, if the suction plate 1 is made to communicate with the intake source so as to have a negative pressure, the suction action of FIG.
As indicated by a phantom line in (b), the uppermost plate material a is first attracted to both end portions of the suction surface 2 by its both end portions, and then the center portion thereof is attracted to the central convex portion of the suction surface 2 in close proximity. Therefore, the uppermost plate material a is easily separated from the lower surface plate material from both ends in sequence and is adsorbed and separated along the adsorption surface 2.

Next, in another embodiment shown in FIGS. 3 and 4, the suction disc 1 is divided at both ends into appropriate lengths, and the upper and lower split portions 1a, 1a are supported on the main body of the suction disc 1 by a shaft support portion. 10, the two divided portions 1a, 1a are respectively connected to the air cylinder mechanism 1
The free ends are moved up and down by means of 1 and 11, and by the upward movement, the suction surfaces of the suction disk body 1 and the divided portions 1a and 1a are refracted, and the suction surfaces 2, 2a and 2a of the respective lower surfaces are bent, so that the suction surface of the suction disk 1 Has a convex curved surface shape.

In this embodiment, the suction plate 1 is connected to the piston 6 rod of the cylinder mechanism 5 via the support member 1b, and the suction plate 1 is moved from the standby position moved upward as shown in FIG.
Is moved downward and brought into contact with or close to the upper surface of the laminate A as indicated by a phantom line in the figure, and then a suction action is applied, the uppermost plate material a is suction-adhered to the suction surface 2, and When tilting both split parts 1a, 1a upward, the adsorbed plate material a also bends along the adsorbing surface 2 into a convex curved surface as shown by a phantom line in FIG. 4, and both ends of the plate material a are easily bent. It can be peeled from the lower plate material surface, and in this state, the suction plate 1 is moved upward to take out the plate materials a one by one from the laminate A as in the previous embodiment.

The convex curved surface shape of the lower suction surface 2 of the suction disk 1 is not limited to the arc shape ((a) of FIG. 6) and the trapezoid ((c) of FIG. 6) shown in the above-mentioned two embodiments. For example, it is arbitrary to form another convex curved surface as shown in (b) and (d) of FIG.

Further, in the above embodiment, the suction surface 2 of the suction plate 1 is
I have described the one-direction middle-high convex curved surface,
The surface perpendicular to this also has a convex pyramid shape, or a quadrangular pyramid shape, or the suction plate 1 has a circular shape and the lower suction surface 2 has a conical shape, which is also effective.

As described above, in the peeling operation by the suction plate 1,
Inevitably 1 when adsorbing due to the bonding relationship between the plate materials
It is not always sucked one by one, but two sheets may be sucked at the same time. In order to prevent this, in the present invention, an appropriate number of vibrators 12 are attached to the suction plate 1 at appropriate places, and two plates are simultaneously moved by the vibration. Adsorption was prevented in advance to ensure the peeling process one by one.

It is preferable that the vibrator 12 is provided as close to the end edge of the suction plate 1 as possible for the purpose of its operation. For example, as shown in FIG. 3, the upper corners of the disc body 1 or the suction plate as shown in FIG. It is desirable to attach it to the side end of 1.

[0018]

According to the present invention, since the lower suction surface of the peeling suction plate is formed in the shape of a convex curved surface of medium height, when the plate material is sucked by the suction surface, the plate material has an edge portion of a central portion. It can be peeled off very easily like peeling the peripheral edge from the lower plate material centering on the middle height part, and since a suitable number of vibrators are attached to the suction plate, it is attached to the lower surface and sucked by the vibration action. It has an effect that the plate material can be shaken off and the plate material can be surely sucked and separated one by one.
