The first and second vacuum adsorbers 60 and 70 are provided in plural number in pairs in the carrier 50 at predetermined intervals.

At least one second vacuum absorber 70 is disposed between the first vacuum absorber 60 or at least one first vacuum absorber 60 is disposed between the second vacuum absorber 70. do.

Preferably, in the panel transport apparatus, the first vacuum adsorber 60 and the second vacuum adsorber 70 are alternately arranged.

The first vacuum absorber 60 is provided with a first attachment cup 62 having a first suction cup 61 adsorbed to the panel P at one end thereof and the other end connected to the carrier 50. do.

The first vacuum cup 61 is connected to a vacuum hose 80 in which a vacuum flow path is formed, and the vacuum hose 80 is a pneumatic pump for inducing the generation of a vacuum state to the first vacuum cup 61 (not shown). ).

The first vacuum cup 61 has a shape in which a plurality of ends are folded in order to increase elasticity.

The first attachment rod 62 is configured to have a predetermined fixed length.

The second vacuum adsorber 70 has a second attachment cup 71 adsorbed on the panel P and a second attachment rod to which the second support cup 71 is mounted and connected to the carrier 50. 72 and a length variable step 73 provided on the second attachment rod 72 to change the length of the second attachment rod 72.

The second vacuum absorber 70 is installed to have a length longer than the first vacuum absorber 60 by the variable length 73.

The second vacuum cup 72 is connected to a vacuum hose 80 in which a vacuum flow path is formed, and the vacuum hose 80 is a pneumatic pump (not shown) to induce the generation of a vacuum state in the second vacuum cup 71. ).

The second vacuum cup 71 has a shape in which a plurality of ends are folded in order to increase elasticity.

When the second attachment rod 72 is described in detail, the second attachment rod 72 has one end connected to the upper attachment rod 72a connected to the carrier 50 and one end of the second burr. It consists of a lower attachment rod 72b equipped with a cup.

The length variable end 73 is provided between the other end of the upper attachment rod 72a and the other end of the lower attachment rod 72b, so that the upper attachment rod 72a and the lower attachment It comprises an elastic member 73a for elastically supporting the rod 72b.

In addition, the other end of the upper attachment rod (72a) is provided with a first projection (73c) is provided with one side of the elastic member (73a), the other end of the lower attachment rod (72b) The 2nd protrusion part 73d in which the other side of 73a is provided is provided.

The length variable stage 73 is provided with an upper insertion hole h1 into which the upper attachment rod 72a is inserted and a lower insertion hole h2 into which the lower attachment rod is inserted. A housing 73b formed to surround the 72c and the second projection 72d is provided.

The housing 73b is configured to restrict the movement of at least one of the upper attachment rod 72a or the lower attachment rod 72b by the restoring force of the elastic member 73a. ) Is smaller than the first protrusion 72c, and the diameter of the second insertion hole h2 is smaller than the second protrusion 72d.

Looking at the operation of the present invention configured as described above are as follows.

After the carrier 50 is moved to the place where the panel is integrated to transport the panel P, the carrier is lowered toward the panel P.

Since the second vacuum suction unit 70 connected to the carrier 50 has a length longer than that of the first vacuum suction unit 60, the second vacuum cup 71 of the second vacuum suction unit first has the panel P. Will be in contact with.

Thereafter, when the carrier 50 continues to descend, the lower attachment rod 72b of the second vacuum absorber 70 compresses the elastic member 73a and moves toward the carrier 50. .

When the first vacuum cup 61 of the first vacuum absorber 60 contacts the surface of the panel P by the lowering of the carrier, the carrier 50 stops the lowering.

Subsequently, a vacuum state is induced in the first vacuum cup 61 and the second vacuum cup 71 by the operation of the pneumatic pump so that the panel P is connected to the first vacuum cup and the second vacuum cup 61, 71. ) Will be adsorbed.

When the carrier 50 is raised, the second vacuum absorber 70 is restored by the elastic force of the elastic member 73a.

By the restoring force of the elastic member, the elastic member 73a pushes the second protrusion 72d of the lower attachment rod 72b to move the lower attachment rod 72b downward.

Therefore, bending occurs in the panel P due to the difference in length between the first vacuum absorber 60 and the second vacuum absorber 70.

Here, in order to bend the panel P, the portion of the panel P adsorbed on the fixed length first vacuum adsorber 60 should be bent downward in a small amount.

Since the first vacuum cup 61 of the first vacuum absorber 60 is folded in an elastic multistage, the panel P adsorbed to the first vacuum absorber 60 may be provided with a margin for bending. .

After the carrier is raised to a predetermined height, the panel P is moved to the work place for press molding by the movement of the carrier 50 in a state where no sag occurs.

The panel transfer apparatus according to the present invention configured as described above is composed of a fixed length vacuum adsorber and a variable length vacuum suction device, such that bending occurs in the panel during transport so that the panel does not sag. To prevent interference between the panel and the work equipment, the work efficiency is high, and the scratches generated on the surface of the panel are prevented, thereby improving the quality.
