Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an apparatus in which a number of vacuum pads are attached to the same surface to attract objects.

(Prior art) As shown in FIG. 2, a shaft cylinder 2 with a vacuum pad 1 fixed to its tip is inserted into a plurality of through holes 3a formed in a vacuum housing 3, and the base of the vacuum pad 1 and the outer periphery of the lower end of the through hole 3a are inserted. A large number of vacuum pads 1 are accurately mounted on the same plane with springs 4 arranged between them, and the entire interior of the vacuum casing 3 is suctioned through a common piping, and a large number of vacuum pads 1 are used to simultaneously remove objects 5.
Although devices for adsorbing the air are known, they have the disadvantage that air leaks from the gap between the shaft tube 2 and the through hole 3a, reducing the vacuum pressure and reducing the adsorption force.
In order to eliminate this drawback, an O-ring or the like is used to eliminate air leakage, but there is a problem in that the sliding resistance increases.

Further, as shown in FIG. 3, the shaft tubes 2 of the vacuum pad 1 are inserted into a plurality of through holes 3a' formed in the mounting plate 3', and the tubes 6 are directly connected to each shaft tube 2 for suction. It was also considered to do so, but since it requires a large number of tubes, it would take up a lot of space, and it would be extremely difficult to use it in places with size restrictions. There was a problem that warping occurred in the parts, making the operation unsmooth.

(Purpose) The object of the present invention is to provide a common piping adsorption device using a vacuum pad that has less sliding resistance, no air leakage, and is more compact than direct piping.

(Structure) In order to achieve the above object, the present invention has a shaft cylinder with a vacuum pad fixed to the tip thereof slidably inserted into a plurality of through holes formed in the vacuum chamber housing, and a shaft cylinder at the rear of each vacuum pad. The base of the elastic pad is fixed so that the opening of the flap-like pad faces in the opposite direction to the vacuum pad, and the pad opening is pressure-sealed to the lower surface of the vacuum chamber casing around the lower end of the through-hole. It is something to do.

Hereinafter, a detailed description will be given based on examples. A shaft cylinder 11 with a vacuum pad 10 fixed to its tip is slidably inserted into a plurality of through holes 12a formed in the vacuum chamber housing 12, and each vacuum pad 10 is
The base of a pad 13 made of an elastic body is fixed to the rear shaft cylinder 11, and the opening 13a of the pad 13 is fixed.
Lower surface 12 of the vacuum chamber casing 12 on the outer periphery of the lower end of the through hole 12a
B is pressure-sealed. 14 is a vacuum chamber housing 12
It is a suction tube that sucks the air inside.

Next, the effect will be explained. A plurality of vacuum pads 10 arranged in a plane 15
When pressed against the surface, the shaft cylinder 11 retreats and the opening 13a of the pad 13 is slightly deformed, and when the suction tube 14 is connected to the suction device, the entire air inside the vacuum chamber housing 12 is suctioned, and each vacuum pad 10 A suction force acts on the object 15 to attract it. At this time, the opening 13a of the pad 13 is pressed and sealed against the lower surface 12b of the vacuum chamber casing 12 on the outer periphery of the lower end of the through hole 12a, so that no air leaks from the through hole 12a.

(Effects) According to the present invention, a shaft cylinder with a vacuum pad fixed to the tip thereof is slidably inserted into a plurality of through holes formed in the vacuum chamber housing, and a rubber pad made of an elastic material is attached to the shaft cylinder at the rear of each vacuum pad. The base is fixed with the opening of the shaped pad facing in the opposite direction to the vacuum pad, and the opening of the pad is pressure-sealed to the bottom surface of the vacuum chamber casing around the lower end of the hole, so objects can be reliably attracted. It is possible to provide a common piping adsorption device using a vacuum pad that can be transported, has low sliding resistance of the vacuum pad, does not have air leakage, and is more compact than direct piping.
