Description

Arrangement of corrugated cardboard for packing box {Apparatus For Reversing Packing Papers}

The present invention relates to a packaging apparatus, and more specifically, for the packaging box for restoring the packaging sheet sheets stacked so that the front and back sides alternately to rise on the top and back to prevent the occurrence of distortion. It relates to a cardboard alignment device.

The wrapping paper for packaging a product will be determined according to the type of the product, and thus a wide variety of wrapping papers are used for each kind of product. Typically, the wrapper is assembled in three-dimensional form. To this end, a process of cutting, pasting and bending sheet-shaped cardboard is performed.

Corrugated cardboard for packing boxes, which are widely used, can increase the rigidity of the box and cushion the impact, and use the corrugated cardboard which is advantageous for reducing the pulp consumption and the weight of the box. Corrugated cardboard is made by adhering corrugating medium of corrugated medium to a liner. Corrugated map may be classified into single faced corrugated fiberboard, double faced, single wall, double wall, triple wall, and triple wall depending on the arrangement of the original cardboard and the corrugated core.

Outer discs, which are located on the outside of packaging boxes, provide resistance against physical shocks or climatic conditions, and at the same time, manila paper with smooth surfaces may be used in consideration of aesthetics, or coated paper may be used. In this case, the properties of the front and back of the cardboard can be different.

As such, the packaging paper provided for the manufacture of the packaging box is often different from each other in the front and back surface, in this case, if only one direction is laminated corrugated cardboard is accelerated bowing. Therefore, in order to solve this problem, the supplier of corrugated cardboard is loaded so that the front and the back are alternately raised upwards, wrapped in a wrap, etc. and then supplied to the user of the packaging box at a predetermined quantity. By canceling the force to bend like a bow to maintain the flatness of the cardboard packaging box is to avoid the problem.

Although it is good for the box maker to have no problems with the quality of the wrapping paper, especially flatness, additional processing is required because the sides of the box must be matched. In other words, the inverted part should be flipped back to its original state so that a certain side always comes up.
