Abstract

PURPOSE: To provide such a thin plate sucking device as ensuring separation of upper and lower thin plates by elevating a sucker which sucks both edges on either longitudinal or cross side of the thin plate and then elevating a sucker which sucks both edges on the other side to reduce an area in face contact of the upper and lower thin plates. CONSTITUTION: A thin plate separating device to separate stacked flexible thin plates after separation one by one from the lower thin plates has suckers to suck the peripheral edges of the thin plates 1 and a frame 5 formed with a lateral frame 3 and a vertical 4 to support the suckers in an elevatable manner. The lateral frame 3 is constructed by right and left frame elements 3a, 3b pivotally mounted at the center in a rotationally movable manner.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin plate separating device for separating stacked stacked flexible rectangular thin plates one by one and separating them from a lower thin plate. The present invention relates to a thin plate separating device which is useful for lifting metal foil and prepreg from a stacked body one by one.

[0002]

2. Description of the Related Art Flexible thin plates such as metal foils and prepregs used for manufacturing laminated plates are rectangular thin plates cut into a predetermined size and stored in a stacked state. It is common practice to lift the thin plates one by one from the top and transfer them to a predetermined position. In order to lift the thin plates one by one, it is necessary to first separate the uppermost thin plate from the lower one. Thus, in order to separate the thin plates, the peripheral edges of the thin plates are vacuum-sucked by the suction plates, and the suction plates that adsorb the vertical or horizontal edges of the thin plates are raised to bend the thin plates in an arc shape with respect to the lower thin plates. The method of separation is adopted. However, even if it is curved in an arcuate shape, it cannot be curved so as to lose its restoring force, and there is a limit to the curvature. That is, the upper and lower thin plates cannot be curved until they are in line contact with each other, and it is unavoidable to keep them in surface contact. Therefore, the uppermost thin plate cannot be reliably separated from the lower thin plate, which causes a major trouble in the thin plate transfer process. In order to eliminate such troubles, after raising the suction plate that adsorbs both vertical edges of the thin plate, release the suction force of this suction plate to return the thin plate to its original state, When the suction plate for sucking the parts is raised, the surface contact area between the upper and lower thin plates decreases, so that the separation between the lower thin plate and the uppermost thin plate becomes more reliable and improved.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to raise a suction plate for adsorbing either one of the vertical and horizontal edges of a thin plate, and then to raise another suction plate for the other edge. (EN) Provided is a thin plate separating device capable of more reliably separating upper and lower thin plates by raising the surface area of the upper and lower thin plates in contact with each other.

[0004]

A thin plate separating apparatus according to a first aspect of the present invention is a thin plate separating device for separating a stacked rectangular thin plate from a lower thin plate. The separating apparatus is provided with a plurality of suction plates 2 for sucking the peripheral edge of the thin plate 1, and a rectangular frame body 5 composed of a horizontal frame 3 and a vertical frame 4 for supporting the suction plates 2 so as to be movable up and down. It is characterized in that it is composed of left and right frame members 3a, 3b that are pivotally attached at the center.

[0005]

The thin plate separating apparatus according to claim 1 of the present invention is a rectangular frame body composed of a horizontal frame 3 and a vertical frame 4 for vertically supporting a plurality of suction plates 2 for suctioning the peripheral edge of the thin plate 1. Equipped with 5,
Since the horizontal frame 3 is composed of the left and right frame members 3a pivotally pivoted at the center, the suction plate 2 is raised and curved in an arc shape, and then the left and right pivotally pivoted at the center. When the frame members 3a, 3b of the horizontal frame 3 composed of the frame members 3a, 3b are rotated upward, the surface contact area between the uppermost thin plate 1 and the lower thin plate 1 is reduced, so that the separation is more reliable.

[0006]

1, 2 and 3 relate to an embodiment of the present invention. FIG. 1 is a top view showing a use state, FIG. 2 is a front view and FIG. 3 is a side view.

As shown in the figure, the thin plate separating apparatus of the present invention comprises a plurality of suction plates 2 for sucking the peripheral edge of the thin plate 1.
The suction plate 2 is connected to an intake pipe 10, and the intake pipe 10 is inserted into a through hole 11 that is formed in the frame 5 and penetrates vertically. The frame body 5 has a rectangular planar shape in which the horizontal frame 3 and the vertical frame 4 are joined, and is substantially in a facing relationship with the peripheral edge of the thin plate 1. The horizontal frame 3 is composed of left and right frame members 3a and 3b pivotally attached at the center, and vertical frames 4 and 4 sandwiching the horizontal frame 3 from both sides are frames centered on a pivot 12 of the frame members 3a and 3b. It reciprocates in a circular orbit having radiuses 3a and 3b. That is, the frame body 5 has a structure in which the vertical frame 4 and the horizontal frame 3 are in the same plane.
State, and pivoting upward about the pivot 12 to V
The frame elements 3a and 3b displaced in a V shape and the vertical frame 4 repeatedly reciprocate between the states shown in FIG. 2 in the two planes of the V shape.

The intake pipe 10 inserted into the through hole 11 of the frame body 5 is vertically and vertically movable through the through hole 11, and a plurality of suction cups 2 are provided on the vertical frame 4 and the horizontal frame 3. 1 repeatedly held reciprocally between the state shown in FIG. 1 in which it is held equidistantly and the state shown in FIG. 2 in which the suction plate 2 mounted vertically on the horizontal frame 3 via the intake pipe 10 is raised. That is, in the step shown in FIG. 2, when the left and right frame elements 3a, 3b rotate upward about the pivot 12 and stop when the frame elements 3a, 3b are tilted at a certain angle, they are attached to the vertical frame 4. Both sides of the thin plate 1 attracted by the suction plate 2 peeled off from the lower thin plate 1, and the uppermost thin plate 1 is curved in a bow shape as a whole.
When the suspension shaft 13 attached to the center of the frame body 5 is raised at this stage, the uppermost thin plate 1 leaves a portion in which the lower thin plate is in close contact, so that the uppermost thin plate 1 and the lower thin plate 1 are joined together. Also causes problems. Therefore,
The step moves from the step of FIG. 2 to the step of FIG. That is,
As shown in FIG. 3, the left and right frame members 3a and 3b rotate downward about the pivot 12 to form a horizontal frame 3 including the frame members 3a and 3b.
And the vertical frame 4 are displaced in the same plane. The intake pipe 10 mounted on the horizontal frame 3 of the frame body 4 displaced in the same plane and the intake pipe 10 of the vertical frame 4 aligned on the same line as the intake pipe 10.
Rises as shown by the arrow, and with this operation, the suction plate 2 connected to these intake pipes 10 rises,
Peel off both sides of the adsorbed thin plate 1 from the lower thin plate 1,
The uppermost thin plate 1 is bowed as a whole. When the suspension shaft 13 is lifted after stepping through this step, the uppermost thin plate 1 can be lifted separately from the lower thin plate 1. That is, since the surface contact area between the uppermost thin plate 1 and the lower thin plate 1 is reduced by the steps 1 and 2, the separation is more reliable.

[0009]

In the thin plate separating apparatus according to the first aspect of the present invention, the surface contact area between the uppermost thin plate 1 and the lower thin plate 1 is reduced, so that the separation is more reliable.
