Description

Paper automatic supply system {A SYSTEM FOR SUPPLING PAPER AUTOMATICALLY}

The present invention relates to an automatic paper supply system capable of automatically supplying paper, and more particularly, by automatically supplying paper used as a separator when loading a glass substrate to cut and measure the length.

In general, flat panel displays such as PDP, LCD, and OLED can be found in various places in the form of various devices such as TVs and outdoor billboards.

These flat panel displays are implemented by forming an electronic circuit pattern on a glass substrate.

After completing the process of forming the electronic circuit pattern on the glass substrate, the glass substrate is loaded and stored on a pallet for transporting the glass substrate or transported to a desired destination using various transportation means.

On the other hand, the manufactured glass substrate is loaded on a pallet or the like for transport and storage, and interleaving paper is used for preventing direct contact between the glass substrates and for stable loading, storage and transport.

Conventionally, when loading a manufactured glass substrate on a pallet, etc., the paper is supplied by releasing the paper from the paper roll, cut to a predetermined length, and overlapped with the transferred glass substrate so that the paper is positioned between the loaded glass substrates.

On the other hand, since the paper applied to the large glass substrate is large, the replacement operation is very cumbersome because the paper roll for supplying the paper is large and heavy.

Conventionally, since workers manually replace these paper rolls, there are problems such as taking a long time for the replacement operation and causing a safety accident during the replacement operation.

In addition, paper must be supplied from a paper roll and cut to a desired length according to the size of the glass substrate. There may be a difference in the length of the , so there is a problem that defects frequently occur.
