[0001] APPARATUS FOR MANUFACTURING BOXES [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box manufacturing field, and more particularly, to a box manufacturing method and a carton manufacturing method, and more particularly, to a carton box for reliably cutting a corrugated cardboard for continuous manufacture of a large number of carton boxes, Manufacturing apparatus.

A corrugated cardboard refers to a cardboard with wavy corrugated paper between one or two sheets of cardboard. Such corrugated cardboard is commonly used for packaging articles due to the buffering action of the cardboard itself and the wavy paper inserted between them.

A packaging box, which is generally manufactured using corrugated cardboard, is composed of, for example, a rectangular plate having a rectangular parallelepiped corresponding to a main body for containing an article, and a wing plate formed to extend to the upper and lower portions of the vertical plate.

Conventionally, when manufacturing a box using such corrugated cardboard, a single or a plurality of corrugated cardboard sheets are stacked to form each blade plate extending from the vertical plate, Respectively.

However, in order to partially cut corrugated paper such as the former, a large amount of labor is required to partially cut the corrugated object, and a plurality of corrugated sheets are stacked as in the latter case, and then the corrugated cardboard is squeezed using a press with a blade, There is a problem that it is difficult to obtain a reliable partial incision site as well as a problem of damaging the blade.

In order to solve such a problem, Korean Unexamined Patent Publication No. 10-2011-0098391 (published on Sep. 1, 2011, entitled " Method of Manufacturing RFID Mounted Box Using Corrugated Board ", Patent Document 1) And then cutting the corrugated cardboard into unit corrugated paper, then printing the information related to the inner wrapped product on the outside of the corrugated cardboard, and cutting the upper and lower wings of the corrugated cardboard continuously.

Nevertheless, the method of cutting the upper and lower wings of corrugated cardboard is not specified in this patent document.

Moreover, no public patent or patent document published so far discloses a method for lowering the defect rate when cutting the upper and lower wings of corrugated cardboard.

Korean Patent Laid-Open No. 10-2011-0098391 (published on Sep. 1, 2011, entitled "Method of Manufacturing RFID Mounted Box Using Corrugated Board Paper")

Here, the sensor is an optical sensor. A representative example of the optical sensor may be an infrared sensor or a photocoupler.

In the present invention, the corrugated cardboard feeder may include: a corrugated cardboard stacker for stacking a plurality of boxes; A sliding operation body for forcibly transferring the lowermost corrugated cardboard sheet among the corrugated boardboards stacked on the corrugated board stacking unit; And a corrugated cardboard insert assembly for cutting off additional supply of corrugated cardboard forcibly supplied by the sliding operation part.

In the present invention, the cutting roller set includes an upper roller having a cutting edge formed in a conveying direction of the corrugated cardboard, and a lower roller having a groove formed at an outer circumferential surface corresponding to at least a cutting edge of the upper roller. And a blade inserted into a groove formed in the lower roller to separate a portion cut from the corrugated cardboard from the groove.

Further, in the present invention, a conveyor belt for conveying the corrugated board formed with the wing plate is formed at the rear end of the controller. The conveyor belt includes a first conveyor belt having a bottom penetrated to convey the corrugated board and to separate the cut-away groove portions separated from the wing plate; And a second conveyor belt for conveying the corrugated cardboard conveyed from the first conveyor belt and dropping the corrugated cardboard at the end by gravity to load the corrugated cardboard.

According to the present invention, the unit corrugated cardboard is supplied, printed, and cut continuously one by one, so that an advantageous effect of manufacturing a box of good quality compared to the conventional one in which the processes are performed all at once is provided.

Further, according to the present invention, it is possible to remarkably reduce the defective rate due to malfunction of the apparatus by judging and displaying whether or not the cutting grooves are uniformly formed from the corrugated cardboard by the controller during the process.

In addition, according to the present invention, since the conveyor belt is installed at the rear end of the apparatus in a double structure, the conveyance of the corrugated cardboard due to the residue of the incision groove coming from the corrugated cardboard can be smoothly loaded without being hindered.
