Description

Vacuum adsorption device {VACUUM SUCTION APPARATUS}

The present invention relates to a vacuum adsorption device, and more particularly, to a vacuum adsorption device capable of stably transporting by adsorbing a glass plate, etc. by forming a vacuum inside the suction line.

Generally, an adsorber is used to fix a towel rack, a small storage container, etc. to glass, tiles, etc. which have a relatively smooth surface by forming a vacuum in a suction plate.

The vacuum adsorber is usually made of a material having flexibility such as rubber, silicone, urethane, etc., and is provided with an adsorbent plate having a space formed on the center thereof. In use, the adsorbent plate is pressurized by pressing the center portion of the adsorption plate against a plane such as a glass plate or a tile. The air present on the center of the gas is discharged to the outside of the adsorption plate to make the space between the glass plate and the adsorption plate into a vacuum state, whereby the adsorption plate is fixed.

In general, the vacuum suction machine discharges the air in the suction plate to the outside by the pressing force to make the space between the glass plate and the suction plate into a vacuum state, thereby fixing the suction plate. There was a problem with insufficient adsorption power.

In the case of adsorbing and transporting a glass panel by weight, such as a glass panel manufacturing process, a vacuum suction pad connected to a vacuum suction line is used.

In this patent application and related patents, Korean Utility Model Registration No. 0483004 has been proposed a vacuum adsorption pad that can remove the cup phenomenon on the surface of the absorbent article.

However, Korea Utility Model Registration No. 0483004 'Vacuum adsorption pad that can remove the cup phenomenon on the surface of the adsorption article' does not secure an area that is sufficiently adhered to the adsorption plate because only the tip of the adsorption plate contacts the surface of the article when the adsorption plate is adsorbed. In case of the article, the adsorption force is weak, and there is a problem that may cause an accident of falling of the conveyed material during transport.

In addition, when transporting the heavy chain goods because the rigidity of the adsorption plate was not secured during the adsorption, there was a risk that the accident of dropping the goods without enduring the weight of the heavy chain goods.

In particular, in the process of polishing the cut surface during the manufacturing process of the glass plate, when the glass plate cleaned with water is adsorbed and transferred to the vacuum adsorption pad, adsorption failure may occur due to water, and the dry glass plate is adsorbed with the vacuum adsorption pad. In the case of transfer, the adsorption defect is caused by the silicon component remaining on the product surface of the glass plate, which causes a problem of frequent accidents during the transfer.

On the other hand, Figure 5 is an enlarged cross-sectional view showing another embodiment of the vacuum adsorption apparatus according to the present invention, referring to Figure 5 the vacuum generating unit 300 of the vacuum pump 310, the vacuum suction line unit 200 Located in the middle may include a liquid storage tank 320 for separating and storing the liquid sucked through the vacuum suction line unit 200.

More specifically, the vacuum suction line unit 200 connects the first vacuum hose 210 and the liquid storage tank 320 and the vacuum pump 310 to connect the liquid storage tank 320 and the suction pad member 100. It may include a second vacuum hose 220.

The positions of the suction disc part 130 and the pressurizing cone part 120 are fixed by the magnetic force of the electromagnet part 142 and the magnetic body 150, so that the suction disc part 130 is lifted even if the weight object to be absorbed 10 is lifted. And the gap between the pressing cone portion 120 is firmly fixed without opening.

Therefore, the lowering of the adsorption force of the adsorption pad member 100 is prevented, and the adsorption disc portion 130 is firmly adsorbed on the surface of the object to be adsorbed so that the adsorption force can be stably maintained during transport.

While the adsorption area is positioned as wide as possible on the surface of (10), the positions of the adsorption disc part 130 and the pressurizing cone part 120 are fixed by the magnetic force of the electromagnet part 142 and the magnetic body 150, and the object to be adsorbed by the weight body. Even if the article 10 is lifted, the gap between the adsorptive disk portion 130 and the pressurizing cone portion 120 is firmly fixed, so that the vacuum pressure in the vacuum space is independent of the weight of the article to be adsorbed, which is a weight body. It can be kept stable.
