Description

Paper feeder {Apparatus for supplying cardboard}

The present invention relates to a paper sheet feeding apparatus, and more particularly, to a paper sheet feeding apparatus that can maintain a good productivity with the reliability of the operation of transferring the box-forming cardboard sheet to the subsequent process one by one.

Typically, the cardboard packaging box is subjected to the process of printing on the surface of the original paper, then cut into a developed view form and the molding is completed in a predetermined standardized form. Each of these major processes can be automated, but the feeding process from the printing process to the cutting and molding process is largely dependent on manual labor. As a result, the feeding position of the corrugated cardboard is not maintained accurately, resulting in a defect in the subsequent process.

According to Korean Patent No. 0431632, “The corrugated paper that has passed through the moving roller moves through the leaf spring, and when the rear end of the corrugated paper reaches the leaf spring, the rear portion of the leading corrugated paper is lifted by the elastic force and the tail The corrugated cardboard of the corrugated cardboard is inserted into the rear part of the leading corrugated sheet and is inserted downward while being advanced. And a structure capable of repeatedly moving the corrugated cardboard into the molding machine.

Korean Registered Patent No.0504999, “The primary corrugated cardboard conveying means (B) which is installed on the lower side of the corrugated cardboard receiving means (A) and conveys the corrugated cardboard which has received a predetermined amount of corrugated cardboard from the corrugated cardboard receiving means (A) and ; Corrugated cardboard rising means (C) is installed on one side of the primary cardboard conveying means (B) and for raising the corrugated cardboard supplied from the primary corrugated cardboard conveying means (B); Secondary corrugated cardboard conveying means (D) installed at an upper side of the corrugated cardboard raising means (C) and conveying the corrugated cardboard which has been raised from the corrugated cardboard raising means (C) and supplied to the corrugated cardboard dropping means; And a cardboard drop means (E) for dropping and supplying the corrugated cardboard conveyed from the secondary cardboard transfer means (D) to the rotary (R).

The aforementioned patents refer to ensuring safety and minimizing installation space while greatly increasing the accuracy of the work. However, the former is a method of transporting the corrugated cardboard while operating the thickness adjusting slide 20 up and down, and the reliability of the operation of conveying the cardboard one by one is somewhat insufficient. The latter is based on the method of dropping, rising, and falling cardboard, but it has a limitation in productivity due to the complicated process.
