Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a suction device, and particularly to an improvement of a suction device suitable for attaching a wireless vehicle identification number reading device, a so-called transponder, to a vehicle outer panel. It is.

In addition to transponders, we also temporarily attach various kanbans and leaflets to the exterior panels of automobiles, attach light display boards to the exterior panels of buses, and attach type indicators such as local and express trains on trains. This invention relates to an improvement of a suction device suitable for installation.

[Conventional technology]

Traditionally, in vehicle assembly factories, when kanbans and other signs for indicating production quantities and contents were simply attached to vehicles, they were hung with hook-like objects, pasted with adhesive tape, or attached with rubber magnets.

[Problem that the invention seeks to solve]

However, conventional attachment methods have problems such as being prone to scratches on the vehicle, insufficient fixing force during attachment, and time-consuming removal.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to strongly secure small items to a vehicle while preventing the vehicle from being scratched, and to also enable easy removal.

[Means for solving problems]

Therefore, in the adsorption device according to the present invention, a support member is interposed on the non-magnetized side of a plate-shaped rubber magnet to fix the mounting plate, and the magnetized side of the rubber magnet is covered with a film. It is characterized by:

Specifically, in the first aspect of the present invention, through a support member □ provided on a part of one side of the mounting plate,

This is an adsorption device characterized by the following.

A second invention also provides a flexible plate magnet attached to the attachment plate via a support member provided on a part of one side of the attachment plate, and a plate to which the attachment plate is attached. a film that covers the entire other side of the plate-shaped magnet; and a film that is connected to the end of the plate-shaped magnet;
The suction device is characterized by comprising a slide member slidably attached to an end of the attachment plate.

Furthermore, a third invention provides a flexible plate magnet attached to the attachment plate via a support member provided on a part of one side of the attachment plate, and a plate to which the attachment plate is attached. An attraction characterized by comprising a film that covers the entire other side of the plate-shaped magnet, and a film support member that is attached to the end of the mounting plate, to which the end of the plate-shaped magnet is fixed and a tension wire is connected. It is a device.

[Effect]

To explain in detail the present invention according to the above configuration, first,
When the adsorption device is placed on an iron plate, which is the object to be adsorbed, the plate-shaped magnet attracts the iron plate due to magnetic force, sandwiching the film.

In this state, if force is applied to the attachment plate to pull the suction device away from the iron plate, the central portion of the plate-shaped magnet will bend, creating a vacuum inside.

As a result, the suction device attracts the iron plate with a strong force due to the magnetic force of the plate magnet and the suction cup action of the curved plate magnet and film.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

(First Embodiment) FIG. 1 is a perspective view showing the first embodiment of the suction device according to the present invention, FIG. 2 is a sectional view showing the suction state of the suction device, and FIG.
The figure is a sectional view showing a state in which the suction device is removed. Fourth
The figure is a sectional view showing a preparation state for removing dust adhering to the suction device, and FIG. 5 is a perspective view showing a state in which dust adhering to the suction device is being removed using a near blower.

The suction bag f&I is composed of a mounting plate 2, a support member 4, a plate-shaped magnet 6, and a film 8.

The mounting plate 2 is used to mount a kanban board, small device, etc. with bolts or the like, and is made of a rigid material.

A plate-shaped magnet 6 is fixed approximately at the center of the back surface of the mounting plate 2 with a support member 4 interposed therebetween. The support member 4 may be made of any material as long as it has the strength to fix the plate magnet 6 in a small area.

The plate magnet 6 is a rubber magnet whose surface that comes into contact with the iron plate 100 to be attracted is magnetized.

The film 8 loosely covers the entire back surface of the plate magnet 6. The ends of the film 8 are fixed to the ends of the mounting plate 2.

Although it is preferable not to use a material that slips easily for the film 8, basically any material other than ferromagnetic material may be used.

The operation of the first embodiment related to the above configuration will be explained as follows.
First, when the attraction device 1 is placed on the iron plate 100, which is the object to be attracted, the plate-shaped magnet 6 attracts the iron plate 100 by magnetic force, and the film 8 is sandwiched therebetween.

Next, when a force is applied to the mounting plate 2 in the direction of arrow A in this state, the center portion 62 of the plate magnet 6 is bent and the space between it and the iron plate 100 approaches a vacuum state.

As a result, the plate magnet 6 is strongly attracted to the iron plate 100 by the suction cup action in addition to the magnetic force action. This attraction force is several times more than the attraction force exerted by the rubber magnet alone.

However, the rubber magnet used for the plate magnet 6 here is simply for preventing air from flowing in from the end of the plate magnet 6, and the magnetic force does not need to be particularly strong.

Further, the end of the plate magnet 6 is pressed against the iron plate 100 by magnetic force, and since the square plate magnet 6 is formed in a flat shape, there is no need to forcefully press it to expel the air inside the suction cup during installation.

Furthermore, when no force is applied to the mounting plate 2 in the direction of the arrow, the suction device 1 does not exhibit suction cup action and is suctioned only by the magnetic force of the rubber magnet, so the suction cup performance may deteriorate even after long-term suction. There isn't.

Next, when removing the suction device 1 from the iron plate 100, first pull the film 8 fixed to the end portion 22 of the mounting plate 2 upward a little with the finger 110.

Accordingly, the vicinity of the end 62 of the plate magnet 6 is pulled upward, and air flows into the suction cup through the gap between the film 8 and the iron plate 100, so that the suction device 1 can be easily removed from the iron plate 100.

Next, a method for removing dust attached to the suction device 1 will be explained. First, as shown in FIG. 4, when the suction bag WL1 is lifted by hand, the film 8 hangs down from the plate magnet 6, A gap 84 is created between them.

In this state, as shown in FIG. 5, air is blown from the side using the near blower 14. As a result, film 8
Dust such as iron powder adhering to the outside of the plate magnet 6 easily falls off because the influence of the magnetic force of the plate magnet 6 is weakened.

Further, dust that has entered the gap 84 between the plate magnet 6 and the film 8 is attracted to the plate magnet 6 made of a rubber magnet and cannot be easily removed.

However, such dust does not damage the surface of the iron plate 100 because there is a film 8 on the outside thereof.

As explained above, the film 8 plays two roles: releasing suction and removing dust.

In the first embodiment, one support member 4 is provided, but two support members 4 may be provided as shown as 42 and 44 in FIG.

In this way, many small suction cups can be formed, and the stability after suction can be improved.

(Second Embodiment) FIG. 7 is a sectional view partially showing an adsorption device according to a second embodiment of the present invention, and FIG. 8 is a sectional view partially showing a state in which adsorption by the adsorption device is released. It is.

In the second embodiment, parts that are the same as those in the first embodiment will be described with the same numbers, and only parts that are different from the first embodiment will be described.

The second embodiment differs from the first embodiment in that the end portion 8 of the film 8
2 is fixed to a ring member 25 slidably attached to the outside of the end 22 of the mounting plate 2.

To explain the operation of the second embodiment of the above configuration, when the ring member 25 is moved with a finger (not shown) in the direction of arrow B in FIG. 8, the end 62 of the plate magnet 6 is pulled upward. Adsorption can be canceled.

(Third Embodiment) FIG. 9 is a sectional view of an adsorption device according to a third embodiment of the present invention.

In the third embodiment as well, parts that are the same as those in the first and second embodiments will be described using the same numbers, and only parts that are different from the first and second embodiments will be described.

That is, the third embodiment differs from the first and second embodiments in that a film support member 27 is provided around the outer periphery of the end 22 of the mounting plate 2, and the end 82 of the film 8 is fixed to this. The film support members 27 are connected to each other by wires 29.

To explain the operation of the third embodiment having the above configuration, by pulling the wire 29 upward, the film 8 can be lifted and the suction can be released.

Although specific embodiments of the present invention have been described above, the present invention is not limited thereto, and various other embodiments that can be implemented by those skilled in the art are possible within the scope of the claims.

For example, in the above embodiments, rubber magnets were used as the plate magnets, but instead of rubber magnets, plastic magnets may be used.

Further, although one or two supporting members are provided, a larger number may be provided.

〔Effect of the invention〕

As explained above, the adsorption device according to the present invention fixes the mounting plate to the non-magnetized side of the plate-shaped rubber magnet by interposing the support member, and fixes the mounting plate to the non-magnetized side of the plate-shaped rubber magnet. Because it is covered with a film, small items can be securely attached to the vehicle with one touch.

In addition, there is no deterioration in performance even during long-term adsorption, and
Removal can be easily performed with little force.

Further, since the film loosely covers the surface of the plate-shaped magnet, attached dust can be easily removed by vibrating the film or blowing air.

Moreover, this can effectively prevent scratches on objects to be attracted, such as vehicles.

Furthermore, since the adsorption force is exerted in accordance with the magnitude of external force during adsorption, it has an excellent effect of being resistant to fluctuations in external force.
