Description

Sheet separator {SHEET SEPARATING MACHINE}

The present invention relates to a sheet separator, and more particularly, to a sheet separator for separating and aligning the sheets (Sheet) remaining in the processing line of the thin plate such as glass substrate.

As is well known, glass substrates used in the manufacture of flat panel displays, such as thin film transistor-liquid crystal displays (TFT-LCDs), plasma display panels (PDPs), and electro luminescent (EL), After dissolving the glass in the glass melting furnace, it is supplied to the melting molding machine to make a glass substrate, cut to meet the primary standard, coated with a protective film on the surface of the glass substrate, and transported to the processing line of the glass substrate. .

On the other hand, in the processing line of the glass substrate, the protective film is removed from the glass substrate, and the glass substrate is cut again to a size that meets the standard of the flat panel display. In the subsequent coating process, an ITO (Indium tin oxide) film is coated on the surface of the glass substrate by, for example, a silica (SiO ₂ ) film as an insulating film and a conductive film. Glass substrates are laminated by transporting several sheets on a cart or other transportation means. In order to prevent the generation of static electricity due to friction of the glass substrates, the glass substrates are laminated between sheets made of natural pulp. Doing. Therefore, after loading one stacked glass substrate into the processing line, the sheets remaining in the processing line must be removed from the glass substrate by the sheet separator.

In general, the sheet is removed from the glass substrate by blowing the compressed air by an air blower, but the sheet is not easily recycled due to the deformation and damage of the sheet, and there is a problem of increasing the disposal cost of the sheet. In particular, by blowing compressed air, dust and particles falling off from the sheet are generated, which hinders the working environment and contaminates the surface of the glass substrate. In the detachment apparatus of Korean Patent Laid-Open Publication No. 2000-47466, a technique is disclosed in which air is sucked through a rotary nozzle to remove the sheet from the glass substrate, and the sheet is removed in a box. However, this technology involves the problem that it is not possible to recycle it because it is collected and disposed of.

On the other hand, in the separator of thin plate and paper of Japanese Patent Laid-Open No. 11-59927, thin plates and paper such as metal sheets are alternately laminated. Disclosed is a technique for separating a thin plate by the operation of the thin plate separator, and removing the remaining paper so as to be easily absorbed and disposed of by the paper removing unit. In the injector of JP-A-11-91964, a technique of adsorbing and removing a protective sheet of a printed circuit board by a separating device is disclosed. However, these techniques are very inadequate for applications where the sheets remaining in the processing line can be separated and recycled without deformation and damage.

The present invention has been made to solve the various problems of the prior art as described above, the object of the present invention is to separate and align without strain and damage so as to enable the recycling of the sheets remaining in the processing line, such as glass substrate. It is to provide a sheet separator that can be.

Another object of the present invention is to provide a sheet separator capable of quickly and accurately separating sheets without interfering with the processing line.

It is still another object of the present invention to provide a sheet extraction and separating device which can perform a very simple and efficient conversion to a flexible production system by a structure capable of separating sheets of various sizes.

A feature of the present invention for achieving the above object is a frame having a table on which sheets can be stacked; A first carriage installed to move in the Y-axis direction with respect to the frame; A second carriage installed to move in the Y-axis direction in parallel with the movement of the first carriage; A third carriage installed to move in the Z-axis direction with respect to the second carriage; A vacuum suction means installed in the third carriage, the vacuum suction means having a vacuum suction tube capable of absorbing one sheet from the sheet separating position for separating the sheet and moving the sheet to a table of the frame; There is provided a sheet separator comprising rotary drive means for rotating the vacuum suction tube of the vacuum suction means.
