The present invention relates to a roller for cutting a packaging box disc, and more particularly, to perform a cutting operation while advancing the packaging box disc in a longitudinal direction, and including a cutting process and a layout configuration of a pre-process and a post-process. The overall layout can be efficiently constructed, and the separate cutter means can be used, and the position can be adjusted in the circumferential direction on the roller, so that the same width of the original box can be used without changing the cutter means. The case of the original case of the packaging box relates to a roller for cutting the packaging box disc that can be used to easily replace only the separate cutter means so that a product of superior quality can be produced and the overall productivity and workability can be improved. .

In general, various types of packaging means are used to prevent damage and damage in the distribution of goods.Because of the advantages of light weight and easy handling of these packaging means, the corrugated cardboard type flat box is made by bending the original disc Packaging boxes are used a lot.

Such a packaging box is a step of supplying a predetermined amount of packaging box discs one by one in a loaded state, printing a predetermined phrase on the packaging box disc, cutting at least six places of the packaging box disc for bending into a cube, It is common to produce a complete packaging box through a process of bending into a cube that is actually used.

Most of the manufacturing process of the packing box is also a generalized automated process.In the initial stage of the process, the original packaging box is supplied at the same time, and the printing process is performed on the original packaging box. The process of bending the original box of the packaging box for the final product is bent at the same time, and a roller for cutting the original box of the packaging box is required for such a post process.

6 and 7 show various embodiments of the conventional cutting box disc cutting roller.

As shown in FIG. 6, the roller 10 includes a plurality of cutter fixing discs 11 and roller shafts 12, and is disposed in accordance with the cutting position of the packing box disc while being attached to the cutter fixing discs 11. Each cutter having a fixed cutter 13 and a cutter groove 14 for accommodating the cutter 13 during the cutting operation and at the same time installed side by side with the roller 10 roller for the cutting operation ( An auxiliary roller 15a serving as a counterpart of 10 is provided.

Accordingly, when the original packaging box passes between the roller 10 and the auxiliary roller 15a, cutouts for bending are formed in the original packaging box discs by the individual cutters 13 of the rollers 10 that are continuously rotating. do.

However, since the roller for cutting the packaging box disc as described above employs an individual cutter 13 that is widely disposed in the longitudinal direction with respect to the packaging box disc proceeding in the width direction, a large-scale equipment including the roller 10 is provided. There are disadvantages that are required, and if the size is changed according to the specifications of the original packaging box, the position of some single cutters 13 can be varied, but most of the rollers 10 and the auxiliary rollers 15a are replaced. There was an inefficiency that had to be done.

In particular, when cutting work, the individual cutter 13 is inserted into the cutter groove 14 while cutting the original packaging box with the packaging box disc in between. There was this.

As shown in FIG. 7, a cylindrical roller 10 including a roller shaft 12, a wooden board 16 for cutter setting attached to the entire circumference of the outer circumferential surface of the roller 10, and the wooden board ( 16) is installed using the integrated cutter 17 to maintain the cutting portion and the outer shape of the original box of the packaging box, and the urethane surface to be in contact with the integrated cutter 17 during the cutting operation and at the same time parallel to the roller 10 The auxiliary roller 15b serving as a counterpart of the roller 10 for cutting operation is provided.

Accordingly, when the original case of the packing box passes between the roller 10 and the auxiliary roller 15b, a cutout for bending is formed on the original box of the packing box by the integrated cutters 17 of the roller 10 that are continuously rotating. .

The cutting box disc cutting roller employing the integrated cutter 17 cuts the packing box disc in such a manner that the integrated cutter 17 contacts with the urethane surface of the auxiliary roller 15b. Has an excellent advantage.

However, the rollers for cutting the box discs as well as the case described above employ an integrated cutter 17 which is widely disposed in the longitudinal direction with respect to the box discs running in the width direction. There is a disadvantage in that the equipment is required, and above all, there is a disadvantage in terms of economics because the integrated cutter 17 and the wooden board 16 surrounding the entire outer circumferential surface of the roller 10 to fix it are expensive. If the size is changed according to the specifications of the original packaging box due to such disadvantages, it is mostly applied only to the packaging box original having one kind of size due to the burden of replacing the expensive integrated cutter 17 and the wooden board 16. There was an easy limit.

Therefore, the present invention has been devised in view of the above, and basically adopts a method of fixing a cutter using a wooden board and a method of cutting the original box of a packaging box in combination with an auxiliary roller on a urethane surface, thereby providing excellent quality. While maintaining its advantages, it adopts a cutter support means that combines a plurality of ring-type drums and a separate cutter means that can be separated and adjusted in each unit. Therefore, the overall size of the equipment can be greatly reduced, and efficient linkage configuration related to the arrangement between front and rear processes is possible, and when it is applied to the original box of the same width box by adopting the detachable cutter means that can be separated and positioned. Can be used as it is without adjusting the cutter means In case of applying to the box with different width and width, it is possible to easily replace only the separate cutter means so that the overall productivity and workability related to the manufacture of the box can be improved. The purpose is to provide.
