Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum suction device used to suction a product using a vacuum device, and use its suction force to lift, transport, take out, or insert the product. It is.

BACKGROUND OF THE INVENTION In recent years, vacuum suction devices have been used to transport, take out, or insert products that have complex shapes and cannot be grasped mechanically, or products that are extremely sensitive to damage.

A conventional vacuum suction device will be described below with reference to the drawings.

FIG. 3a shows a vacuum cup which is a suction part of a conventional vacuum suction device.A cup 1 made of an elastic material such as rubber is connected to an air suction hole 3 of a connector 2 connected to the top of the cup 1. Air is expelled and adsorbs the product.

FIG. 3 shows the state in which the cup 1 has absorbed the product 6. As shown, a suction force acts on the cup 1 and the cup 1 expands along the surface of the product 6 until an equilibrium state is reached.

Problems to be Solved by the Invention However, with the above configuration, when the cup sucks the product, the cup slides on the surface of the product and expands to attract the product. For this reason, if there is dirt or dust on the surface of the product, it will cause scratches, and depending on the material of the cup, the cup will spread due to the suction force, causing scratches on the slippery part of the cup.So-called cup marks have been applied to the product. Therefore, if the surface of the product is easily damaged, such as a painted surface, plastic, or aluminum plate, it is necessary to be very careful about the material and shape of the cup 1.

In view of the above-mentioned problems, the present invention provides a vacuum suction device that does not leave cup marks on the product and prevents damage to the surface by not rubbing the surface even when there is dirt or dust.

Means for Solving the Problems In order to solve the above problems, the vacuum suction device of the present invention has the following features:
A plate-shaped body having a through-hole is placed on the surface of the article to be sucked, and the cup is pressed against the surface of the article through the plate-shaped body so that the through-hole is located inside the cup, and suction is applied to the surface of the article.

According to the above structure, the cup expands along the surface of the plate during the vacuum suction operation, and only the suction force acts on the surface of the article through the through hole. Therefore, the conventional cup spreads along the surface of the article. The objective is to provide a product that is free from damage such as cup marks and scratches that occur due to spreading along the surface.

EXAMPLE Hereinafter, a vacuum suction device according to an example of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, in which a shows the state before the suction operation, and b shows the state in which an article is suctioned. In FIG. 1, 1, 2.3 are a cup, a connector, and an air suction hole, respectively, and have the same structure as the conventional one. 4 is a box-shaped slide plate made of a slightly flexible material such as rubber, synthetic resin, paper, etc. The bottom plate and the top plate each have a slide plate with a diameter smaller than the outer diameter of the tip of the cup 1. diameter first and second through holes5.
7 is provided. Then, as shown in FIG. 1, the cup 1 is inserted into the box-like body through the through hole 6 in FIG. 1 by utilizing its elastic deformation, and moves integrally with the movement of the cup 1. It is configured like this. In the above configuration, when an article is to be suctioned, the cup 1 is pressed against the surface of the article 6 via the bottom plate of the slide plate 4, as shown in FIG. 1, and the article is suctioned. During this suction operation, the cup 1 deforms as in the conventional case, but the article 6 and the slide plate 4 remain as they are, and the cup 1 spreads along the bottom plate of the slide plate 4. Therefore, if the material and surface properties of the slide plate 4 are taken into consideration to ensure sufficient airtightness between the slide plate 4 and the surface of the article 6 and between the slide plate and the cup, the suction force will be It acts directly on the article 6 through the through hole 6 of No. 1.

FIG. 2 shows another embodiment in which the slide plate 4 is made of a rigid body with strong mechanical strength, and the contact surface is made of rubber in order to obtain airtightness between the slide plate 4 and the surface of the article 6. , a soft material layer 8 made of synthetic resin or the like is formed. Further, in the above-mentioned embodiment, the slide plate 4 is formed into a box shape and is configured to move up and down together with the cup 1, but the slide plate 4 is simply a flat plate, and the flat slide plate is placed on the surface of the article. It may also be suctioned with the cap 1 after being placed on the holder.

Effects of the Invention As described above, in the present invention, since a slide plate is interposed between one cup and the surface of the article, there is no fear of cup marks or scratches on the surface of the article.
