[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the construction of a suction transporting device for a long plate according to the present invention.

In the suction transfer device 1, a plurality of suction pads 3 are arranged in the apparatus main body 2 in the longitudinal direction of the long plate W at predetermined intervals, and each suction pad 3 is communicated with the vacuum generator 4. There is.

More specifically, the apparatus main body 2 is vertically movable by an elevating means (not shown), and is movable left and right, front and rear, or both by a conveying means (not shown).

Each suction pad 3 has a pad portion 31.
Is hung from the apparatus main body 2 through two guide rods 32.

The pad portion 31 is formed to have a shape and size suitable for the long plate W to be adsorbed. In the present embodiment, the pad portion 31 is formed as a hollow rectangular parallelepiped and has a suction hole (not shown) on the bottom surface. It is provided.

The upper ends of the two guide rods 32 are penetratingly arranged in the apparatus main body 2 through a bush 33 so as to be movable up and down, and an end plate 34 is provided at the upper end. 34 is supported by the apparatus main body 2 so as to suspend each guide rod 32 via a collar 35 for level adjustment.

The lengths of the two collars 35 that are interposed between the left and right guide rods 32 that support one pad portion 31 are different. Therefore, the left and right guide rods 32
Have different lengths projecting downward from the apparatus main body 2, and the pad portion 31 is connected to the lower ends thereof.

As a result, each pad portion 31 is supported by the left and right guide rods 32 in an inclined state, and
The adjacent pad portions 31 are arranged so as to be inclined by the collar 35 in opposite directions.

The level may be adjusted by interposing a nut or the like in place of the collar 35.

The pad portion 31 of each guide rod 32
Springs 36 are respectively interposed between and the device main body 2, and the urging force of the springs 36 pushes the pad portion 31 downward. Further, when the pad portion 31 adsorbs the long plate body W, the pad portion 31 moves upward through the guide rod 32 against the biasing force of the spring 36, so that the pad portion 31 moves. Stable adsorption to W is made.

Then, one end of each hose 41 is connected to each pad portion 31 thus supported by the apparatus main body 2, and the other end of each hose 41 is connected to the vacuum generator 4. . A valve 42 is provided at the confluence of each hose 41, and the valve 42 is turned on / off.
Thus, the long plate W is sucked and released by the suction pad 3.

Next, the case where the long plates W stacked in layers by the suction transfer device 1 described above are transferred will be described.

First, the suction pad 3 is placed above the uppermost long plate W by the movement of the apparatus main body 2, and each pad portion 3 is placed.
While bringing 1 into contact with the uppermost long plate W, the valve 42 is turned on to cause the vacuum generating device 4 to adsorb each pad portion 31 to the uppermost long plate W.

At this time, the uppermost long plate W is attracted to the pad portions 31 in a wavy state as a whole because the pad portions 31 are inclined. As a result, even if the long plate bodies W are stacked in a perfectly overlapping state, when the uppermost long plate body W is adsorbed, air is generated between the long plate bodies W below it. It is possible to enter and adsorb and lift only the uppermost long plate W.

When the uppermost long plate W is lifted as described above, the apparatus main body 2 is moved to transfer the long plate W to a predetermined place, and then the valve 42 is turned off. By stopping the suction by the vacuum generating device 4, the long plate W is separated from the suction pad 3. By repeating this operation, the stacked long plate bodies W are sequentially transferred from the uppermost stage to a predetermined place.

As a result, it is possible to reliably prevent the long plate W underneath the uppermost plate W from being stuck to the upper plate W and being conveyed together, thereby preventing the occurrence of troubles. be able to. In particular, the thinner the long plate W is, the more effective it is.

The strength of the urging force of each spring 36, the inclination angle of the pad portion 31 and the like are taken into consideration so as to obtain a stable suction by taking into consideration the material of the long plate W to be sucked and transferred. It may be set appropriately.

FIG. 2 shows another embodiment of the adsorption transfer device for a long plate according to the present invention. The same members as those of the adsorption transfer device for the long plate described above are designated by the same reference numerals, and the description thereof will be omitted.

The suction transfer device 1 includes the guide rods 3
The pad portions 37 each having a substantially conical shape are individually provided on the pad 2, and the vacuum generator 4 is connected to the pad portions 37 through a hose 41.

The pad portion 37 of each suction pad 3 is
The height positions of the collars 35 having different lengths are different from each other. Therefore, when the long plate W is adsorbed by each pad portion 31, the long plate W is adsorbed in a wavy state as a whole as in the above, whereby the above-described long length is absorbed. It is possible to obtain the same effect as that of the adsorption transfer device for the scale plate.

[0033]

As described above, according to the adsorption transfer device for a long plate of the present invention, the long plate is adsorbed by the adsorbing means in a wavy state in the longitudinal direction. ,
Even if the long plates are stacked in a perfectly stacked condition, only the top long plate can be adsorbed and lifted, and the top long plate below It is possible to reliably prevent the plate body from being stuck and transported together.
It is possible to prevent the occurrence of troubles due to this. Particularly, it is more effective that the long plate is a thin plate.
