Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The packaging box 100 shown in Fig. 1 is manufactured using a wrapping paper in the form of a sheet having a developed view as shown in Fig. The wrapping paper 100 'includes a rectangular upper plate 1, a lower plate 3 having the same shape as the upper plate 1, outer plates 5 and 7 projecting from respective sides of the upper plate 1 and the lower plate 3, 9, 11, 13, 15); An inner plate 17 provided between the upper plate 1 and the lower plate 3 in the same shape as the outer plates 5, 7, 9, 11, 13, 15; A first wing plate 19 protruding from both sides of the inner plate 17; And a second wing plate 21 protruding from both sides of one of the outer plates 5, 7, 9, 11, 13, 15 provided on the side surface of the lower plate 3. The packaging box has a hexagonal shape with a low height and a wide area. Therefore, the upper plate 1 and the lower plate 3 are formed in a quadrilateral shape having a similar horizontal length and vertical length, and the side plates 5, 7, 9, 11, 13, 15,

An insertion hole 50 is formed at a corner of the upper plate 1 and the outer plate 9 and the insertion hole 50 is formed by inserting a finger to load the wrapping paper 100, So that it is easy to use.

Since the present invention relates to a method for manufacturing a packaging box, the present invention will be described below.

The wrapping paper 100 'has a corrugated cardboard structure formed by vertically adhering the surface fingers 27 and 29 with the corrugated paper 25 bent in a corrugated shape as the center as shown in the enlarged view of FIG. It is a well-known fact that the corrugated paper 25 has a bone direction. When folding a corrugated cardboard, corrugated cardboard folds easily when the corrugation direction (W) and the folding line are the same. Conversely, when the corrugation direction W and the folding line are staggered, the corrugated cardboard is not easily folded.

A plurality of support protrusions 22 are formed on the upper and lower surfaces of the surface fingers 27 and 29 at regular intervals on the inner surface and the outer surface of the corrugated paper 25 provided in a zigzag manner.

The support protrusions are closely contacted with the longitudinal direction of the corrugation to reduce the load transmitted to the upper plate 1 and the lower plate 3 to minimize deflection of the upper plate 1 and the lower plate 3.

In the automatic packaging process of the present invention, the wrapping paper is supplied to the system in a folded state as shown in Fig. 4 (a) for efficiency of the logistics. Therefore, in order to insert the product P, a force F is applied to the packaging box 100, which is supplied in a folded state, and the packaging box 100 is unfolded through a process as shown in FIGS. 4 (b) and 4 (c). In the process of unfolding the package box, it receives vertical force (F ') to bend its middle part.

4, the packing box 100 can be easily folded, which poses a serious problem in the automatic packaging system. Therefore, the present invention eliminates the problem of folding the corrugation as shown by the dashed line in Fig. Here, the left and right directions refer to directions in which the direction W of the corrugation of the wrapping paper is the same as the direction in which the wrapping paper or the product is fed.

According to another aspect of the present invention, the outer plates (5, 7, 9, 11, 13, 15), the inner plate (17), and the first and second blade plates (19, 21) This is for the purpose of eliminating the problem that the wing plates 19 and 21 protrude from the side surface of the packaging box when the perpendicular angle is not correct in the process of expanding and bonding the wrapping paper. The outer plates 5, 7, 9, 11, 13, 15, the inner plate 17 and the first and second wing plates 19, 21 are formed in a rhombus shape in consideration of the error. The angle K of the longitudinal sides of the outer plates 5, 7, 9, 11, 13 and 15, the inner plate 17 and the first and second blade plates 19 and 21 is preferably 7 to 15 degrees.

According to another aspect of the present invention, the folding is applied to the outer surface (1a) of the wrapping paper in whole or in part by pulling along the folding line on the developed drawing, The bending portion 31 of the first embodiment can be provided. According to the bent portion, even if folded as shown by the one-dot chain line in Fig. 5, the problem of being torn by the tensile force applied to the outer surface 1a can be eliminated.

According to another aspect of the present invention, sheath 37 (sewing) can be formed entirely or partly in a dotted line along the fold line on the developed view. This is to make sure that it can be folded mechanically during the folding process. The folded packaging box must be able to be unfolded stably in accordance with the procedure of FIG. 4 even in various situations, and can not be easily removed if a place is pressed, absorbed water, or impurities. Therefore, in this case, a sheath (sewing) is made along the folding line so that it can be easily removed,

The packaging box of the present invention is fed one by one by a suction type supply device 33 as shown in Fig. 3 and next to the conveyor to which the product P is supplied. In this process, the packaging box is unfolded through the process shown in FIG. The product is poured into the packaging box and then wrapped using hot melt adhesive. The product and the packaging box are fed along the direction indicated by the arrow (Y) and subjected to the insertion and adhesion process.

According to the embodiment of the present invention, as shown in FIG. 6, the hot melt is sprayed to the upper surface of the lower side plate 11 through the injection nozzle 35 while the upper side plate 13 is first folded. That is, by spraying the hot melt 36 in the downward direction, the peripheral equipment is prevented from being contaminated by the hot melt 36.

This will be described below with reference to Fig. 7 is a diagram showing a process of folding the second wing plate 21 inside the box in the process of removing the wrapping paper in a plan view. The packaging box is transported in the direction indicated by the arrow and the push bar 41 is rotated about its own hinge axis 43 and strikes the outer surface of the second wing plate 21 to be folded as shown by the dashed line . Then, the guide 45 guides the second blade 21 in a folded state.

Here, the length L of the second wing plate 45 will vary depending on the size of the packaging box. When the length L is changed, the push bars 41 to 45 must be set again. Otherwise, if the length L is long, the second wing plate 21 is hooked on the guide 45 and is not folded. It is very troublesome to set the push bars 41 to 45 each time according to the packaging box 100 to be manufactured. According to the present invention, the length L of the second wing plate 21 is set to a specific length, for example, 40 to 50 mm. Therefore, it is possible to eliminate the inconvenience of re-setting the push bars 41 to 45 even when using any packing box. Since the second wing plate 21 is the same as the first wing plate 19, the first wing plate 19 can be designed with a certain restriction similarly to the second wing plate 21.

The packaging box according to the present invention is mechanically subjected to a removing process and must be accurately unfolded or folded without any error. If it is infested or crushed during the packaging and transportation process, it may be difficult to put it into the automation system. Therefore, when transporting the folded packing box for removing the packing box, it is preferable to load the pallet in the vertical position and then carry it lightly tied with the wrap without being strongly tied with the banding. This makes it possible to eliminate the problem that a large load is applied to the wrapping paper to be pressed. When loading horizontally, the packing box at the bottom may be subject to a great pressure and may be difficult to remove. As described above, the packaging box for applying the present invention receives careful care from the delivery.

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
