Description

How to pack cotton containers into a carton

The present invention relates to a method and apparatus for packaging a plurality of normal and narrow cotton containers in a cardboard box for receiving instant food such as a bowl surface, and more particularly, to the load of the cotton containers loaded in the box. The present invention relates to a packaging method and apparatus for preventing deformation and damage caused by the same, and minimizing the amount of space accommodated, thereby reducing the size of the packaging box and reducing the logistics costs such as transportation, storage, and loading of raw materials.

In general, companies that manufacture instant noodles, such as instant foods, have difficulties in productivity improvement, cost reduction, and supply and demand of workers.In order to solve this problem, factories that pack food containers, such as bowl noodles, in boxes Is automating the packaging process.

A conventional method of automatically packing a bowl side container in a box is shown in Figs.

First, FIG. 6 illustrates a state in which a cotton container 1 is packaged in a packaging box 100 by a conventional packaging apparatus and method. The packaging method includes a supplying step of supplying cotton containers in two rows, and It consists of a sorting step of repeating the transfer and stop operation to package the cotton container supplied in two rows, and a packaging step of absorbing and putting in a box when the cotton container is stopped after moving, the conventional cotton container produced conventionally (1) is somewhat different in height and size, but all of them are manufactured in a shape where the upper part of opening the container is wide and the bottom surface is narrow.

In addition, after the noodles and soup in the cotton container (1), the supply is automatically made to the transport line (conveyor) to package in the packaging box 100 in the state of individually packaging. At this time, the packaging unit is suitable for the packaging method of 12 pieces, 16 pieces and 24 pieces, and is made by a supply step of supplying the cotton container (1) in two rows to increase the efficiency of the packaging.

All the surface containers (1) supplied in two rows through the supplying step reaches an alignment step in which the bottom surface is in contact with the transfer line in the upright state, and the feeding and stopping are repeatedly performed. Two rows of X 3-4 pieces are adsorbed and placed in the packing box 100 in the air, and the cardboard 101 is placed thereon. Then, when the cotton container 1 is stopped after the transfer, the two rows of X 3 ~ 3 are added to the adsorber again. 4 boxes are adsorbed and placed in the cardboard 101 on the cotton container 1 already contained in the packaging box 100 to make two stages. Get

In addition, the cardboard box 102 is placed in a state in which 16 pieces are put in the packing box 100, and the two-stage X 4 pieces of two rows X 4 adsorbed to the adsorber are stopped again while the cotton container 1 is transported and stopped. When placed in the cardboard 102 on the surface container 1 contained in the three stages to make a total of 24 cotton containers (1) are packed in the cross-sectional shape shown in FIG.

FIG. 7 is a view illustrating a state in which a cotton container 1 is packaged in a packaging box 100 by another conventional packaging method of improving the method of FIG. 6, wherein the packaging method supplies two rows of cotton containers. A supplying step, an inverting step of vertically placing the cotton containers 1 supplied in the second row, an alignment step of repeating a transfer and stop operation to package the cotton containers supplied in the second row, and the cotton container It is made of a packing step of the process of adsorbing and packing in the box when it is stopped after moving.

The packaging method is the same as the method of packaging in the state of Figure 6 between the cotton container (1) is placed in two rows of two to three stages in the state of the cardboard container 101 or cardboard 102 is inserted The process of being packed and packaged in the packing box 100 is the same, but in order to reduce the size of the packing box 100, there is an inversion step between the feeding step and the sorting step.

The reversal step is a step for reducing the space in the longitudinal direction of the packing box 100, by inverting the cotton container (1) to be transferred in two rows through the supplying step so that the top and bottom are mutually reversed after the packing of the container ( 1) The top and bottom of the contact with each other is made to shrink the space.

However, in the two conventional packaging methods described above, the surface containers 1 loaded in two to three stages are in contact with each other because their upper and lower surfaces are in contact with each other, so that the load applied to the packaging box 100 during transportation and storage of the warehouse. When the cotton containers (1) in the packing box is pressed by, the bottom surface of the cotton containers (1) is pressed to the upper lid to cause breakage and deformation to lose the value of the goods, the surface to be placed Bars are packed by sandwiching the hard cardboard (101,102) between the containers (1), thereby increasing the packaging cost of the product, there is a problem that the weight of the packaging box is also heavy.

Moreover, the first packaging method described above, the length of the packaging box 100 because the surface container 1 contained in the packaging box 100 is packaged in a state in which the wide lid portions are in contact with each other, as shown in FIGS. 6 and 8. The direction and the width are inevitably made large, so that the manufacturing cost of the packing box 100 is increased, and there is a lot of empty space inside the packing box 100, so when a large amount of packing box 100 is loaded, the goods may also be loaded by the load. And there is a problem that the packaging box is deformed or broken.

In addition, in the second packaging method, as shown in Figs. 7 and 8, the surface containers 1 contained in the packaging box 100 are arranged so that the top and bottom are alternately arranged in a line direction lined with the front and rear, so that the space of the length is narrowed, but the width is narrow. In the direction of the wide lid portion is also faced with the forward and reverse packaging is inevitably made wider than the longitudinal direction of the packaging box 100, the manufacturing cost of the packaging box 100 is raised, the packaging box 100 When there is a lot of empty space inside the packaging box 100, there is a problem that the product and the packaging box is deformed or damaged by the load.

Therefore, all of the above packaging methods, there is a problem that the use of cardboard to prevent deformation or breakage, and the enormous loss of the raw material of the packaging box is made large, and enormous due to the storage or transportation of bulky packaging box There was an uneconomical problem in which the logistics costs were spent.

The present invention is to solve the conventional problems as described above, the object of the present invention is that the surface containers loaded in the packaging box in the row (row line) direction and five (a pair of front and back) up, down, left and right. Minimize the space accommodated so that the right side is interchanged with each other, and to provide a packaging method and apparatus to prevent the deformation and breakage by the lid and the bottom surface contact each other to prevent the deformation and breakage.

Another object of the present invention is to provide a packaging method and apparatus for obtaining a reduction effect of the raw materials of the packaging box, thereby reducing the logistics cost of transportation, storage, loading and the like.
