There is a problem that occurs. Also, as shown in FIG. 11, even if the suction position is adjusted so that only the lip portion 2A of the suction pad 2 contacts the surface of the plate glass 4 so that the actuator thrust does not act directly, the suction pad 2 is evacuated. At this time, the volume of air in the adsorption pad 2 decreases, and the adsorption direction variation (a slight lift amount) occurs in the plate glass 4 adsorbed by the adsorption pad 2 (see FIG. 12), causing plate cracking or the like in the plate glass 4. There's a problem. In particular, this problem remarkably appears when the plate glass 4 is cut.

A vacuum space 16A is formed in the suction pad 16.
The vacuum space 16A is connected to a vacuum device (not shown) via the flow path 16B and the flexible pipe 26. A suction deformation preventing member 30 is provided in the suction pad 16. As shown in FIG. 2, the suction deformation preventing member 30 has a hardness of 6
It is formed of urethane rubber of about 0 in a rectangular shape, and the suction deformation preventing member 30 is attached to the suction pad 16 radially at predetermined intervals around the central axis of the suction pad 16.

When adsorbing the sheet glass 32, the inside of the adsorption pad 16 is in a vacuum state and a force for adsorbing the sheet glass 32 acts, so that the sheet glass 32 is sucked up. In this case, since the lip of the suction pad 16 is formed of a soft elastic member, it is pushed up by the plate glass 32 and elastically deforms upward by the S dimension. Then, the plate glass 32 sucked up is attached to the suction deformation preventing member 3
0, 30 ... (see FIG. 3). Therefore, the deformation of the plate glass 32 due to the suction force of the suction pad 16 is prevented by the suction deformation preventing members 30, 30 ..., It is possible to prevent the plate glass 32 from cracking.

に有効である。The operation of the plate glass adsorbing apparatus according to the present invention having the above-described structure will be described. First, the lifting cylinder 12
The support pad 14 is lifted to lift the suction pad to the standby position. Next, when the adhering plate glass 32 is conveyed to a predetermined position, the rod portion 12B of the elevating cylinder 12 is extended downward and the supporting member 14 is lowered. As a result, the suction pad 16 follows the lowering of the support member 14 and moves down to the suction position where the suction pad 16 contacts the surface of the plate glass 32 by its own weight. In this case, the lifting cylinder 12
Since the thrust of the suction pad 16 is separated from the suction pad 16, only the own weight of the suction pad 16 or the like acts on the plate glass 32.
Therefore, since the load acting on the plate glass 32 is reduced,
It is possible to prevent the plate glass 32 from cracking. In particular, this effect is effective when the cut glass 32 is a thin plate.

Is adsorbed on the adsorption pad 16. In this case, the suction pad 16 is made of a material having a soft lip and elastically deformable, and the suction deformation preventing member 3 is provided in the suction pad 16.
0, 30 ... Are provided at positions higher than the lip position of the suction pad 16 by S dimension.

Touch 30 ... Thereby, the deformation of the plate glass 32 due to the suction force of the suction pad 16 can be suppressed to a predetermined amount or less. Further, since the shaft 20 is not fixed to the support member 14, when the suction pad 16 is evacuated and the volume of the suction pad 16 is reduced during the suction, the suction pad 16 will not move.
Descends with. This prevents the plate glass 32 from being lifted during adsorption.

い。Thus, the suction deformation preventing members 30, 30
By suppressing the amount of deformation of the plate glass 32 and further preventing the plate glass 32 from being lifted by freeing the suction pad 16, it is possible to prevent the plate glass 32 from cracking. In particular, this effect works effectively when the plate glass 32 is a thin plate glass having a cut line. Further, when the suction device 10 sucks the plate glass 32 with the suction pad 16,
The suction pad 16 is lowered to the surface of the plate glass 32 by its own weight to adsorb the plate glass 32. As described above, when adsorbing the plate glass 32, it is not necessary to fix the adsorption pad 16 to the adsorption position. Therefore, even when the plate glass 32 changes from the thick plate t 1 shown in FIG. 4 to the thin plate t 2 shown in FIG. It is not necessary to adjust the suction position of the suction pad 16 according to the change in plate thickness.

In the case of the thick plate t 1 shown in FIG. 8, when the air cylinder 12 is extended to the suction position, the suction pad 16 stops above and the spring 40 is fully extended. Therefore, the weight of the shaft 20 and the suction pad 16 acts on the plate glass 32 of the thick plate t 1 . On the other hand, in the case where the plate glass 32 is the thin plate t 2 shown in FIG. 9, when the air cylinder 12 is extended to the suction position, the suction pad 16 descends to a lower level than in FIG. As a result, the spring 40 is maintained in a compressed state, and the weight of the shaft 20 and the suction pad 16 is reduced by the urging force of the spring 40. Thus, as the plate thickness of the plate glass 32 becomes thinner, the shaft 2
0 and the amount of relaxation of the weight of the suction pad 16 are large, so that the plate glass 32 is not cracked when the air cylinder 12 is extended to the suction position.

れ等が発生することを防止できる。As described above, according to the plate glass suction device of the present invention, when the support member is lowered, the thrust of the actuator is separated from the suction pad, and the suction pad follows the lowering of the support member. Then, it descends to the suction position by its own weight. As a result, the thrust of the actuator is not transmitted to the plate glass via the suction pad, so that the plate glass can be prevented from being cracked or the like.

る。Further, according to the present invention, the suction deformation preventing member is provided in the suction pad. The plate glass comes into contact with the suction deformation preventing member before the plate glass sucked by the suction pad is deformed by the suction force of the suction pad. As a result, the plate glass adsorbed on the adsorption pad is not deformed by the adsorbing force of the adsorption pad, so that the plate glass can be prevented from being cracked or the like. Further, even if the plate thickness of the plate glass changes, the height adjustment is unnecessary.

Therefore, when the suction pad descends by its own weight and contacts the plate glass, the weight acting on the shaft acting on the plate glass and the plate glass of the suction pad is relieved by the elastic member.
In this way, by reducing the weight applied to the plate glass such as the suction pad and the shaft, it is possible to adsorb the plate glass without causing plate cracks or the like in the plate glass.
