Auto folding device for packing box

The present invention relates to a box folding automation device that can quickly fold a series of flat box integrally provided to accommodate objects such as relatively heavy fruits without manual work, and more particularly, a folding process of a flat box that is continuously supplied. In addition to providing more accurate and accurate working requirements by inducing full automation, the improvement of this method of work can prevent the folding failure that can frequently occur during the folding process, thus maximizing productivity and the loss of raw materials. And it relates to a box folding automation device that can omit a separate additional process.

In general, paper boxes using thick cardboard (corrugated cardboard) are mainly used to package and transport the goods. Conventionally, wooden or plastic packaging containers have been used in consideration of the safety of packaging, but using these packaging containers not only increases the logistics cost due to the weight of the packaging container, but also bears a significant portion of the manufacturing cost. In addition, there have been problems of deforestation caused by the use of wood and environmental pollution caused by the use of plastic materials.

Therefore, most products manufactured in industrial fields today use paper boxes made of thick corrugated paper as packaging containers except for special cases for their packaging and transportation.

The paper box mainly used today is formed by cutting the corrugated cardboard to form a bottom surface at the center portion thereof, and by forming the front, rear, left and right wall surfaces in the vertical direction based on the bottom surface, and forming the front and rear wall surfaces. Or by forming a lid extending from the left, right wall surface to form a packaging container of the cube as a whole, it was to be able to accommodate a variety of products therein.

However, such a conventional paper box is a paper fabric made of a thick corrugated paper that can withstand a small impact from the outside to some extent, but for the storage and transportation of the packaged products individually packaged paper box It builds up on top of each other from the bottom. In this case, the packaged product placed on the bottom receives the load of all packaged products placed on the upper side, and the load is applied to the side wall of the packaging container. The packaging container itself is frequently crushed.

This phenomenon occurs more prominently when the product packaged inside the paper box is a heavy item, which is the most serious problem in the field of packaging of electronic products such as LCD panel and PDP panel which are the most competitive in Korea. Is appearing.

At present, the industrial site uses a method of additionally embedding a separate corrugated cardboard reinforcement wall to withstand the upper pressure in a conventional paper box in order to overcome the dent caused by the compression of such packaging containers, and using two corrugated cardboards 1 As a corrugated sheet of paper, another corrugated reinforcing wall surface is formed, and as another corrugated sheet, a conventional paper box is used.

However, the former reinforcing wall surface addition method has a disadvantage of having to go through a number of work processes for its packaging, the latter method of forming a separate reinforcement wall surface is used to double the raw material (corrugated cardboard) and also a large number of operations There is a disadvantage to go through the process.

For example, according to the Republic of Korea Utility Model Registration No. 20-319372 "packaging box for storing and transporting goods", in order to be able to withstand the load of the upper side, cardboard paper fabric vertically inside both sides of the packaging container (paper box) It forms a side extension that allows it to stand. The side extensions are attached to each side by applying an adhesive on their ends, and form a small triangular accommodating space therebetween.

However, in the case of the Republic of Korea Utility Model Registration No. 20-319372, it provides effective reinforcement to withstand the load from the side extension portion to some extent, so that the items stored therein, such as pizza, are light articles. Although it can be used, in the case of a heavy article such as an LCD panel or a PDP panel, it is still impossible to overcome the distortion caused by the upper load.

In addition, when the object of the present invention can be applied to the object such as fruit, such problems are more pronounced, in consideration of the property that requires absolute protection from damage to the product in the case of giving a double paper such as protective paper, the assembly process is There is another problem that is not smooth and there is a need to improve it.

On the other hand, the feeder packaging box supplied in a flat form consists of a main body and the airfoil auxiliary plate and the opening and closing cover extending from the main body, such a packaging box is used to fold into a three-dimensional packaging box at the production site, the packaging box made in the field The folding process is to push the main body of the packing box on both sides to take a rectangular shape → the process of bending the airfoil auxiliary plate formed on the back of the main body to push it horizontally with the main body → opening and closing the cover formed on the rear of the main body in 2 steps Bending process → is made to be divided into the process of pushing the coupling plate formed in the opening and closing cover to the main body, the packaging box completed through the above process takes the shape of a three-dimensional rectangular enclosure with the front open.

For example, there is Utility Model Registration No. 0280443, "Automatic Folding Device for Packaging Box," which is designed to automatically carry out folding work of a packaging box, which was performed by hand, and folding of the packaging box that was made manually by the technical idea. By automatically proceeding the work, the desired purpose of eliminating manpower shortages and improving productivity per hour could be achieved. However, in the process of finishing the sequential folding process for the packing box, the folding work and the main body and the joining plate formed on the opening and closing cover were completed. Often, the combination operation of is not done correctly.

In particular, since the unfinished folding process has to be manually performed by the worker, productivity not only decreases, but also causes inconvenience in the process, and in some cases, the opening and closing cover of the packaging box is damaged during the folding process, causing economic loss. The problem could not be solved.

The present invention was created in order to more actively solve the above problems, and proposes to fold a thick paper box in an automated manner without manual work, as well as the occurrence of errors and defect rate that can occur during the folding process The main purpose is to significantly reduce the mass production of packaging boxes with higher product value.

It is characterized by continuing the cycle of.

Here, the paper box applicable to the box-folding automation device of the present invention by way of example is as follows, but the technical concept of the paper box to be described later is 10-2013-0039527 "folding" Paper box structure that is easy to handle and an assembly method using the same.

As shown in Figure 21, the structure of the paper box applied to the present invention is largely the bottom plate 10; Electric plates; It is made of a mutual combination of the side plate, and the front plate and the side plate adopts a double structure, respectively, for convenience of description, divided into the upper front plate 21 and the lower front plate 22, the upper side plate 31 and the lower side plate 32 It was.

In detail, each front plate and side plate are provided to correspond to each other with respect to the slope direction starting from the square bottom plate 10, the front plate and the side plate are respectively the upper front plate 21 and the lower front plate 22, It includes that is divided into the upper side plate 31 and the lower side plate (32). Here, the reinforcement paper 23 may be further adopted at both ends of the lower front plate 22 in the longitudinal direction, and the mounting edges 24 having the length longer than those of the reinforcement paper may be additionally employed at both ends of the upper front plate 21. To achieve the desired purpose.

In addition, the lower front plate 22 and the lower side plate 32 are partitioned by a fold line from the bottom plate 10. The fold line, which is a boundary area between the lower side plate and the bottom plate, drills the oval-shaped fitting holes 40 spaced apart from each other in the direction of the bottom plate on the fold line, and the boundary between the lower side plate and the bottom plate in the space between the plurality of fitting holes. It can be configured by additionally drilling the gripping hole (41) divided into two from the central region of the fold line as an area.

The fitting hole 40 is for fixing and restraining the fitting piece 34 of the upper side plate to be described later, it must be accompanied essentially for the solid maintenance of the assembled state when assembling the paper box of the present invention. At this time, the formation position of the fitting hole is preferably drilled in the space biased to the bottom plate on the boundary line between the lower side plate and the bottom plate, and eventually the substantially hollow space in the state where one side of the fitting hole is engaged on the fold line which is the boundary between the lower side plate and the bottom plate. Is formed in the bottom plate 10 region. This structure allows the binding force of the fitting piece 34 to be most increased while considering the corresponding thickness surface of the double fold line in the process of folding the upper side plate 31 and the lower side plate 32 by the double fold line. To do this.

The gripping hole 41 is for providing convenience to the user when the paper box is moved or handled, and is possible by allowing the user's hand to be positioned by a hollow space formed by the gripping hole.

In other words, the depression 35 is one means for excluding the hollow part of the gripping hole perforated in the lower side plate area when the box is folded. In other words, the assembled box is covered with all the gripping holes separated by the upper side plate end lower plate 32, if you want to disassemble the assembled box according to the situation by lifting the upper side plate 31 upwards The process of separating the fitting piece 34 from the fitting hole 40 may be difficult. Thus, by forming a recessed portion 35 at the end of the upper side plate 31 as one way to solve this, it is possible to expect more efficient operation by preventing the upper side plate does not completely cover the gripping hole 41 even during assembly.

The upper front plate 21 and the lower front plate 22 may also be divided and knitted by a double fold line like the upper side plate and the lower side plate. In addition, in the space between the mounting blades 24 and the reinforcing paper 23 provided at both ends of the upper plate and the lower plate, an inclined surface 33 having an inverse gradient from the lower plate to the upper plate is knitted, and thus the slope is completed. A fold line for the division of the upper plate and the mounting base is adopted. Formation of the inclined surface 33 in the above is accompanied for a more complete sealing of the joint portion of the corresponding component, and thoroughly prevents the exposed space (holes, etc.) resulting from the round shape or other specific shape to prevent the inside of the external foreign matter, etc. It is to prevent inflow.
