JPS59212328A - Device to separately pick up doughnut-shaped thin plate with hole - Google Patents

Abstract

PURPOSE:To prevent more than one plate from being picked up simultaneously by blowing air into the core part of piled doughnut-shaped thin plates with a hole so that each of them is separated from the other. CONSTITUTION:When a pick-up main body 4 is pushed onto piled doughnut- shaped thin plates 3 with pressure in order to suck up the plates through a vacuum-suction port 6, air from an air blowing port 10 is blown into a recessed chamber 5. Then the air is supplied to an air space 9, which is formed between piled thin plates 3 and a core shaft 2, in order to ease separation of one plate 3 from the other 3. With this contrivance, difficulty in separation of piled thin plates can be solved, while picking up of more than one plate at the same time can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to an improvement in a device for separating and taking out thin plates with donut-shaped holes stored in a stacked state in a thin plate holder. A conventional device of this kind, which is the object of the improvement of the present invention, will be described with reference to FIGS. 1 and 2. FIG.

Reference numeral 1 denotes a base of a thin plate holder, which has a core shaft 2 in its center, and a large number of thin plates 5 with donut-shaped holes are fitted into the core shaft 2 and held in a stacked manner. Reference numeral 4 denotes a main body of a device for separating and extracting a thin plate 6 with a donut-shaped hole, which has a cylindrical shape and has a recessed hole 5 in the center into which the core shaft 2 penetrates, and the main body 4 around the recessed hole 5 has a cylindrical shape. A vacuum suction hole 6 is provided in a ring shape on the end face. A vacuum suction port 7 communicates with the vacuum suction hole 6, and is replaced by a vacuum pump and a hose 8 (not shown). The thin plate 6 with a donut-shaped hole held in the thin plate holder is assembled into a thin plate holder by pressing the end surface of the main body 4 against the thin plate 5 and applying vacuum suction. You can separate and take out 91 sheets at a time.

By the way, in the above-mentioned conventional device, separation is performed by the weight of the thin plate 6, so when the uppermost thin plate 5 is pulled up by suction, the second thin plate comes into close contact with the uppermost thin plate, resulting in separation. This is not done and the two thin plates are pulled up at the same time.
, sometimes. When a plurality of thin plates are in close contact with each other, one to several thin plates are pulled up at the same time.

Is there a hole in the donut hole where there is no possibility of the phenomenon occurring according to the present invention? The object of the present invention is to provide an Ilf plate separation and extraction device.

The device for separating and extracting thin plates with donut-shaped holes of the present invention includes a base, a blood-stained core shaft, and a large number of donut-shaped holes stacked and held on a similar thin plate holder. In a device that separates and takes out f-boards one by one, the core shaft has a broken-circuit oval shape, forms a space between it and the thin plate, and is in pressure contact with the thin plate at the center of the main body of the device. A recessed hole into which the core shaft enters is provided in the part, a wall suction hole is provided in the end face of the main body around the recessed hole, and a sudden air blowing hole that opens into the recessed hole is provided in the main body. It is characterized by

An embodiment of the present invention will be explained with reference to FIGS. 6 and 4. In the figure, numerals 1 to 8 indicate the same things as in FIG. The thin plate holder of the present invention has a cylindrical circumference 1 of a core shaft 2.
A part of 111 is removed from both sides to form a disconnected elliptical shape, and a space 9 is formed between it and the thin plate 6 with a donut-shaped hole. On the other hand, the main body 4 of the separating and extracting device is provided with an air blowing hole 10 that opens into the recessed hole 5.

Reference numeral 11 denotes a hose for feeding air into the air blowing hole 10.

[Effects of the Invention] Since the present invention has the above-described structure, when the main body 4 is pressed onto the stacked donut-shaped thin plate 5 with holes and suction is carried out by the vacuum suction hole B, the concave air is removed from the air blowing hole 10. By blowing air into the holes 5 and supplying air to the space 9 formed between the laminated thin plates 6 and the core shaft 2, the thin plates 6 can be easily separated.

(Thus, the difficulty in separating thin plates, which was a problem in the conventional apparatus shown in FIG. 1, is eliminated.) This has the effect of achieving the object of the invention stated at the beginning.
