Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a suction device used for suctioning a wall of a wall-walking robot or for handling a building board or the like.

[0002]

[Prior Art]

 As a suction device of this type, conventionally, as shown in FIGS. 6 and 7, a suction plate 2 having a plurality of suction holes 1 is connected to a negative pressure generating device 3 and the suction holes 1 and A manifold 5 communicating through the communication hole 4 is attached, and the suction holes 1 are urged by the flow of air in the communication hole 4 in a direction to close the communication hole 4 and some air flows when the communication hole 4 is closed. It has been considered that the valve 6 is provided, which causes leakage of air and is biased in the opening direction by the elastic force.

When the suction device is sucked onto the suction surface 7 such as a wall surface or a construction board, when the suction plate 2 is pressed against the suction surface 7, the negative pressure generating device 3 is operated. The air in each sucker hole 1 is exhausted to the outside from the manifold 5 through each communicating hole 4, and the inside of each sucker hole 1 becomes a negative pressure and becomes the same pressure as the inside of the manifold 5, so that the valve 6 is opened. The sucker plate 2 is held, and the sucked surface 7 sucks the sucked surface 7.

At this time, if there is unevenness in a part of the sucked surface 7 and a part of the suction plate 2 does not come into close contact with the sucked surface 7 and some of the suction holes 1 do not have a negative pressure. Since the flow of air passing through the communication hole 4 increases, the valve 6 is closed due to the pressure difference between the suction hole 1 and the manifold 5, and the communication hole 4 is closed. The pressure generating action is prevented from being lowered, and a sufficient suction force is exerted as an adsorption device. Further, even when the valve 6 is in the closed state, the communication hole 4 is not completely blocked and the suction hole 1 Since air is slightly leaking from the suction surface to the manifold 5 side, when the suction plate 2 is separated from the suction surface 7 and moved to another suction surface 7 having no unevenness, the suction plate 2 will 7, so that the air in the sucker hole 1 can be easily removed from the manifold 6 through the slight gap between the valve 6 and the communication hole 4. After being exhausted through 5, the inside of the suction cup hole 1 and the inside of the manifold 5 have the same pressure, the valve 6 inside the suction cup hole 1 is opened by the elastic force, and the inside of the suction cup hole 1 is kept at a negative pressure, so that adsorption is performed. ing.

[0005]

[Problems to be solved by the device]

 However, the adsorption device as described above requires as many valves 6 as the number of suction cup holes 1, and each valve 6 must be attached one by one at the time of manufacture, which is very time-consuming and each valve 6 has to be installed. It was weak against external forces, and it was often bent or broken during its manufacture or use.

In view of the above situation, the present invention intends to provide an adsorption device that allows the valves to be easily attached in a lump and is also strong in strength and is unlikely to be deformed or damaged during manufacture or during use. It is a thing.

[0007]

[Means for Solving the Problems]

 According to the present invention, a suction plate having a plurality of suction holes is provided with a manifold which is connected to a negative pressure generator and communicates with the suction holes through communication holes. In a suction device equipped with a valve that is urged in the direction of closing the communication hole by the flow of air in the communication hole and causes a slight air leakage when the communication hole is closed and is urged in the opening direction by the elastic force. The suction plate and the manifold are a single thin plate having an outer shape substantially equal to that of the plate and having punched holes formed at the corresponding positions of the suction cup holes so that a valve element movably supported by the support pieces is formed. It is characterized in that the valve is constituted by being interposed between the valve and the valve.

[0008]

[Action]

 Therefore, a single thin plate having an outer shape substantially equal to that of the suction plate and punching holes formed at the positions corresponding to the suction holes so that a valve element movably supported by the support piece is formed, Since the valve is constructed by interposing it between the valve and the manifold, the valves can be easily mounted all at once, and the valve element is supported by the support piece, so It is stronger and less likely to bend or break during its manufacture or use.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 5 show an embodiment of the present invention. In the drawings, the parts denoted by the same reference numerals as those in FIGS. 6 and 7 represent the same things, and the basic configuration is shown in FIG. Although it is similar to the conventional one shown in FIG. 7, the feature of the present embodiment is that, as shown in FIGS. 1 to 5, one thin plate 8 is made to substantially match the outer shape of the suction plate 2. A punching hole 9 is collectively formed at a position corresponding to each sucker hole 1 by a press or the like, and a valve element 11 movably supported by a support piece 10 is formed. The one thin plate 8 is attached to the sucker plate 2 And the manifold 5 are urged in the direction of closing the communication hole 4 by the air flow of the communication hole 4 and at the time of closing the communication hole 4, some air leaks and the elastic force causes the opening direction. The point is that the valve 6 that is biased to is configured.

In FIG. 4, 12 is a seal member made of rubber or the like attached to the manifold 5 side of each valve body 11, and 13 is a normal state in which no air force acts on each valve body 11. Is a large diameter portion formed on the valve body 11 side of the communication hole 4 so that the communication hole 4 is held in an open state.

In this embodiment, when the suction device is sucked onto the suction surface 7 such as a wall surface or a building board, the negative pressure generating device 3 is pressed while the suction plate 2 is pressed against the suction surface 7. When operated, the air in each suction cup hole 1 is exhausted to the outside from the manifold 5 through each communication hole 4, and the inside of each suction cup hole 1 becomes a negative pressure and becomes the same pressure as the inside of the manifold 5, so that the valve The valve element 11 supported by the support piece 10 of 6 maintains the open state, and the suction plate 2 is adsorbed to the adsorbed surface 7, and at this time, the adsorbed surface 7 has irregularities on a part thereof. If a part of the suction plate 2 does not come into close contact with the attracted surface 7 and a part of the suction holes 1 does not have a negative pressure, the air flow through the communication holes 4 increases and the suction holes 1 and Due to the differential pressure in the manifold 5, the valve body 11 is sucked toward the communication hole 4 side and the valve 6 is closed. Since the communication hole 4 is closed, the negative pressure generating action of the other suction cup holes 1 is prevented from decreasing, and a sufficient suction force is exhibited as the suction device. Further, even if the valve 6 is closed, the communication hole 4 is closed. Since air is slightly leaked from the suction cup hole 1 to the manifold 5 side without completely closing the suction cup plate 2, the suction cup plate 2 is separated from the suction surface 7 and moved to another suction surface 7 having no unevenness. At this time, the sucker plate 2 comes into close contact with the attracted surface 7, and the air in the sucker hole 1 is exhausted through the manifold 5 from the slight gap between the valve 6 and the communication hole 4, and the sucker hole 1 and the manifold 5 Becomes the same pressure, the valve 6 in the suction cup hole 1 is opened by the elastic force, the inside of the suction cup hole 1 is held at a negative pressure, and adsorption is performed.

Further, in the case of this embodiment, a punching hole is formed so that a valve body 11 having an outer shape substantially equal to that of the suction plate 2 and movably supported by the support piece 10 is formed at a position corresponding to each suction hole 1. Since a single thin plate 8 formed by drilling 9 is interposed between the suction plate 2 and the manifold 5 to form the valve 6, the valves 6 can be easily mounted collectively. At the same time, since the valve element 11 is supported by the support piece 10, the valve element 11 is strong against the force from the outside and is less likely to bend or break during its manufacture or use.

It should be noted that the adsorption device of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the scope of the present invention.
