{Packing box manufacturing system}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a packaging box manufacturing system, and more particularly to a packaging box manufacturing system that includes a folding process for regularly bending a corrugated cardboard sheet, a binding process for binding the end portions of the folded corrugated cardboard sheets, The present invention relates to a packaging box manufacturing system for continuously performing a series of processes in accordance with the molding of a packaging box including a discharging process of stacking the packaging boxes in a unit amount and discharging the packaging boxes.

As is well known, a box used for storing and transporting fruits and products is generally manufactured by connecting one side of a pair of box members and the other side of the box member.

In detail, the manufacturing process of the box is such that one side of a pair of box members is superimposed on each other, and then one side of the overlapped box member is mutually bound through an iron core, and both sides of the box member are folded inward to overlap each other And then connecting the other sides overlapped with each other through the iron core.

Conventionally, a dedicated device capable of automatically performing a series of processes according to the above-mentioned box production has not been proposed. The worker directly connects one end of a pair of box members with an iron core, And the other side is connected to each other by iron core, labor productivity is remarkably reduced and an additional cost due to manufacturing is excessively generated, and it is pointed out that the uniformity of quality is hard to be secured.

In order to solve this problem, the inventor of the present invention has proposed a process of supplying a pair of box members through Korean Patent Registration No. 10-0801110, a process of overlapping one side of the pair of box members, A process of joining mutually opposite sides of the box member, a process of folding both sides of the box member inward to mutually overlap each other, and a process of joining the other overlapped ends through the iron core, A box manufacturing apparatus has been proposed.

With the spread of such a manufacturing apparatus, it has become possible to automate manufacturing of a box which was previously dependent on manual work.

However, if a long corrugated cardboard is inserted into the system, it is difficult to form a uniform bend because it is not bent.

In addition, since the molded packaging boxes are discharged one by one, the worker must align and pack the discharged packaging boxes by putting them into the binder apparatus through the post-operation. Therefore, It is pointed out that the problem is demanding hard labor.

In order to solve the above problems, an object of the present invention is to provide a method of manufacturing a corrugated cardboard, comprising: a folding step of bending a corrugated cardboard to form a folded corrugated cardboard; And a discharging step of stacking the packed boxes in a unit amount and discharging the packed boxes, in a stepwise manner.
