DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer suction hand having a simple structure which can be applied to a load which is difficult to transfer by suction, such as a load packed in a cardboard box.

[0002]

2. Description of the Related Art As shown in FIG. 3, while a suction pad 2 is in contact with a load 1, air in the pad is exhausted by a vacuum pump 7 through a port 3 and a hose 5 through a port 3. Exhaust through mouth 8. Therefore, the luggage 1 can be suctioned and conveyed by the hanging bracket 4. However, in this method, if the surface of the package 1 is not smooth, a vacuum pressure is not generated in the pad 2, so that the transport target is limited.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a suction hand having a simple structure which can cope with various forms of a suction surface.

[0004]

SUMMARY OF THE INVENTION A chuck body 12 and a thin seal or film material 23 provided with a number of cuts 23a in the radial direction are attached to the outer periphery of the chuck body 12, and the thin seal material or film material 23 is provided. The cut 23 outside the mounting portion of
A multi-piece elastic pressing plate member 24 having a diameter smaller than that of the seal thin member or the film member 23 is provided at a position covering “a”.

Further, the chuck body is connected to an air source via a flexible hose and an electromagnetic valve to make the chuck body approach the baggage, and first, air is fed into the chuck body so that a thin material or a film material is put on the surface of the baggage. After that, the vacuum pressure was applied to absorb the luggage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given with reference to FIGS. Reference numeral 11 denotes a load having a non-smooth surface, and reference numeral 12 denotes a bowl-shaped chuck body which is attracted to the load 11. A lifting bracket 13 is fixed to the chuck body 12, and a lifting tool 15 is mounted via a ball joint 14. In the example shown in the figure, the chuck body is bowl-shaped, but the planar shape may of course be rectangular or other shapes other than round.

The chuck body 12 is a flexible hose 1
At 6, it is connected to an air source 18 via a solenoid valve 17. The air source 18 needs to be excellent in both exhaust performance and intake performance such as a turbo fan. 21 is a valve exhaust port.

Reference numeral 23 denotes a multi-piece seal thin or film material which is attached to the outer periphery of the chuck body 12 and has a plurality of cuts 23a in the radial direction. Reference numeral 24 denotes a multi-piece elastic pressing plate member, which is annularly disposed outside the mounting portion of the seal thin material 23 or the film material 23. Reference numeral 22 denotes a seal / elastic receiving member which is similarly annularly disposed on the inner peripheral surface of the seal thin material or the film material 23.

[0009]

[Operation] First, the chuck body 12 is brought close to the surface of the baggage 1 and the air source 1 is introduced into a space surrounded by a thin material or a film material 23.
Air is allowed to flow in through the flexible hose 16 from the nozzle 8. Then, the thin seal material 23 slightly floats above the surface of the load 1 and its tip is almost parallel along the uneven surface of the load. Next, the supply of air from the air source 18 is stopped.
Then, the air which has floated the seal thin material 23 until now disappears, and the seal thin material 23 is pressed toward the surface of the load 1 by the action of the atmospheric pressure toward the air source 18. In this case, the seal thin material 2
Since there is a radial cut 23a around the outside of 3
The degree of adhesion between the surface irregularities and the seal thin material 23 is increased. Thus, the thin seal material fits the luggage surface and the cut 23a
Is pressed down while the elastic holding plate 24 covers. Although a little air flows into the gap 23a, the air that has flowed in from the gap 23a is always exhausted by the air source 18, and an appropriate low vacuum pressure required for suction is obtained, so that the suction can be carried.

[0010]

[Effect] A seal thin material or a film material provided with a number of cuts in the radial direction is attached to an outer peripheral portion of a bowl-shaped chuck main body, and a position covering the cut outside the mounting portion of the seal thin material or the film material. To
A multi-piece elastic pressing plate member smaller in diameter than the seal thin material or the film material was provided.

[0011] With such a configuration, the seal thin material or the film material having the cut is well adapted to the surface of the load, and there is no large air leakage. In particular, since air flows in moderately and on average from the many cuts during suction, a stepped ball box or the like having a weak surface can be gently sucked and conveyed.

Since the holding plate is attached to the outside of the thin material or the film material at a position covering the cut, the stiffness of the thin material or the film material is reinforced and air leakage from the cut can be properly held.
