BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device used for suctioning a wall of a wall-walking robot or handling an architectural board.

[0002]

2. Description of the Prior Art Conventionally, as shown in FIGS. 6 and 7, a suction plate of this kind is connected to a suction plate 2 having a plurality of suction holes 1 and connected to a negative pressure generating device 3 as shown in FIGS. Manifold 5 communicating with each suction hole 1 through communication hole 4
In the suction holes 1, the air is urged in the direction of closing the communication holes 4 by the flow of air through the communication holes 4, and a slight air leak occurs when the communication holes 4 are closed, and the air flows in the opening direction due to elastic force. An arrangement with an energized valve 6 was considered.

When the suction device is sucked to the suction surface 7 such as a wall surface or a building board, the suction device 2 is operated while the suction plate 2 is pressed against the suction surface 7. The air in the suction holes 1 is exhausted from the manifold 5 to the outside through the communication holes 4, and the pressure in the suction holes 1 becomes negative and the same as that in the manifold 5, so that the valve 6 is kept open. Then, the suction plate 2 is attracted to the attracted surface 7.

At this time, if a part of the suction surface 7 has irregularities or the like, a part of the suction plate 2 does not adhere to the suction surface 7, and the inside of some suction holes 1 does not become negative pressure, The flow of air passing through the communication hole 4 increases, and the differential pressure between the suction hole 1 and the manifold 5 causes the valve 6 to be closed so that the communication hole 4 is closed.
Therefore, the negative pressure generating action of the other suction hole 1 is prevented from lowering, and a sufficient suction force is exhibited as a suction device. Further, even if the valve 6 is closed, the communication hole is not opened. 4
Was not completely closed, and air slightly leaked from the suction hole 1 to the manifold 5 side. Therefore, the suction plate 2 was separated from the suction surface 7 and moved to another suction surface 7 having no irregularities. At this time, the suction plate 2 comes into close contact with the surface 7 to be sucked,
The air in the suction hole 1 is exhausted from the slight gap between the valve 6 and the communication hole 4 through the manifold 5, and the pressure in the suction hole 1 and the inside of the manifold 5 become the same, and the valve 6 in the suction hole 1 is resilient. When opened, the suction hole 1 is maintained at a negative pressure, and suction is performed.

[0005]

However, in the suction device as described above, the valves 6 are required by the number of the suction holes 1, and at the time of manufacture, each valve 6 must be attached one by one. The valve 6 is troublesome, and each of the valves 6 is vulnerable to an external force. In many cases, the valve 6 is bent or broken at the time of manufacture or use.

The present invention has been made in view of the above circumstances and aims to provide a suction device which can easily and collectively mount valves, and which is strong in strength and is not easily deformed or damaged during manufacture or use. Things.

[0007]

According to the present invention, a suction plate having a plurality of suction holes is provided with a manifold connected to a negative pressure generator and connected to the suction holes through communication holes. In each of the suction holes, a valve is provided which is urged in the direction of closing the communication hole by the flow of air in the communication hole and generates a small amount of air leakage when the communication hole is closed, and is urged in the opening direction by elastic force. In the suction device described above, a single thin plate having an outer shape substantially equal to the suction plate and having a punched hole formed at a position corresponding to each suction hole so as to form a valve body movably supported by a support piece is formed. The valve is constituted by being interposed between a suction plate and a manifold.

[0008]

Accordingly, one thin plate having a substantially same outer shape as the suction plate and having a punched hole formed at a position corresponding to each suction hole so as to form a valve body movably supported by a support piece is formed. Since the valve is constructed by interposing it between the suction plate and the manifold, the valve can be easily installed in a lump, and the valve body is supported by the support piece. And it is less likely to bend or break during manufacture or use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of the present invention.
In the drawings, the portions denoted by the same reference numerals as those in FIGS. 6 and 7 represent the same components, and the basic configuration is the same as that of the conventional one shown in FIGS. Where
As shown in FIGS. 1 to 5, punching holes 9 are collectively punched by a press or the like at a position corresponding to each sucker hole 1 of one thin plate 8 substantially matching the outer shape of the sucker plate 2. By forming a valve body 11 movably supported by 10 and interposing the one thin plate 8 between the suction plate 2 and the manifold 5, the communication hole 4 is closed by the flow of air in the communication hole 4. That is, the valve 6 is urged in the opening direction and generates a slight air leak when the communication hole 4 is closed, and is urged in the opening direction by elastic force.

In FIG. 4, reference numeral 12 denotes a seal member made of rubber or the like adhered to the manifold 5 side of each valve element 11, and 13 denotes a communication hole in a normal state where no air force acts on each valve element 11. 4 is a large-diameter portion formed on the valve body 11 side of the communication hole 4 so as to be held in an open state.

In the present embodiment, when the suction device is to be sucked to the suction surface 7 such as a wall surface or a building board, the negative pressure generating device 3 is operated while the suction plate 2 is pressed against the suction surface 7. When actuated, the air in each suction hole 1 becomes
Is exhausted from the manifold 5 to the outside through the suction port, and the inside of each suction hole 1 becomes negative pressure and becomes the same pressure as the inside of the manifold 5, so that the valve element 11 supported by the support piece 10 of the valve 6 maintains the open state. Then, the suction plate 2 is attracted to the surface 7 to be attracted,
At this time, a part of the suction surface 7 has irregularities and the like, and a part of the sucker plate 2 does not adhere to the suction surface 7 and some of the suction holes 1
If the pressure in the inside does not become a negative pressure, the flow of air passing through the communication hole 4 increases, and the differential pressure between the suction hole 1 and the manifold 5 causes the valve body 11 to be sucked to the communication hole 4 side and the valve 6 to be closed. In this state, the communication hole 4 is closed, so that the negative pressure generating action of the other suction holes 1 is prevented from being reduced, and a sufficient suction force is exhibited as a suction device. In addition, even if the valve 6 is closed, Since the communication hole 4 is not completely closed and air is slightly leaked from the suction hole 1 to the manifold 5 side, the suction plate 2 is separated from the suction surface 7 and the suction surface 2 is moved to another suction surface 7 having no irregularities. When the suction plate 2 is moved, the suction plate 2 comes into close contact with the suctioned surface 7, and the air in the suction hole 1 is exhausted from the slight gap between the valve 6 and the communication hole 4 through the manifold 5. 5 has the same pressure, the valve 6 in the suction hole 1 is opened by elastic force, Inner is held at a negative pressure, the adsorption is carried out.

Further, in the case of the present embodiment, the punching holes 9 are formed so as to form a valve body 11 which has an outer shape substantially equal to that of the suction cup plate 2 and is movably supported by a support piece 10 at a position corresponding to each suction hole 1. A single thin plate 8 is formed between the suction plate 2 and the manifold 5 to form the valve 6, so that the mounting of the valve 6 can be performed easily and collectively. Since the valve element 11 is supported by the support piece 10, the valve element 11 is strong against external force, and is less likely to bend or break during manufacture or use.

Incidentally, the adsorption apparatus of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.

[0015]

As described above, according to the suction device of the present invention, the mounting of the valve can be easily performed in a lump, and the valve body is supported by the supporting piece, so that the strength is increased. An excellent effect that deformation and breakage during use or use can be suppressed.
