Description

How to glue label paper to cardboard {adhering method of a label sheet on the corrugated cardboard and its adhering roller}

The present invention relates to a method of adhering label paper to corrugated cardboard, and more particularly, to a method of attaching a label coated with a yub to a large cardboard packaging box, and to increasing productivity and reducing a defective rate, and a paper roll used therefor. .

In particular, the present invention was developed to meet the era of globalization in accordance with the era of distribution revolution, and related to a technology for manufacturing a large-sized color box that could not be made cleanly and effectively due to the limitations of conventional offset printing and lamination and processes. will be

In general, a corrugated cardboard packaging box displays various kinds of goods on the outer surface of the packaging box in order to display a product packaged therein and to advertise. Corrugated packaging box is made of a rough surface of the corrugated cardboard itself is difficult to form a beautiful printing surface when printing on the upper surface of the corrugated cardboard. In addition, for this reason, it is impossible to apply a U.V (U.V) coating having the best friction resistance in the case of the conventional case.

Therefore, in order to make the packaging cardboard box more luxurious, it is attached to the cardboard using a coated sheet paper (label) on the outer surface of the cardboard box, in this case, the labeling paper is very thin and difficult to attach the work.

In particular, in the case of a large box, the offset printing, coating, and laminating work have limitations in specifications and methods, and in order to make one corrugated box, the corrugated box is manufactured in two separate forms, and each of the separated cardboard boxes The productivity is extremely low since the water-based or oil-coated maniard cardboard printout is attached to the front surface (not partially laminated) and then semi-automatically attached to each other to form a single cardboard box. .

As described above, when manufacturing a large cardboard box capable of offset printing and conventional lamination, it is separated into two and printed and coated on a thick manila cardboard within a limited size that can be printed or laminated, and then laminated on the front of the cardboard. Since there was only a method, a large amount of pasting, that is, a lot of moisture, after the laminated packaging box was dried, deformation, that is, warping occurred. Therefore, additional steps are required to recalibrate it when the consumer uses it, and the yield rate of defective boxes is high.

In addition, when the moisture content is high and warpage occurs, the compressive strength of the corrugated cardboard is lowered, and thus the performance of the corrugated cardboard itself is lowered.

In addition, in order to manufacture a large box, when preparing two separate pieces of paper, because the two sheets of non-standard size is prepared, not only the specification is incorrect, but also the position of the paper is not accurate, two sheets of cardboard produced separately Frequent mixing often increases the defective rate

The present invention has been invented to solve the above problems and the other problems described below, to make a high-quality corrugated cardboard packaging box is formed on the corrugated cardboard coating, and previously offset art printing and lamination When printing large sized boxes that were impossible to produce at the same time by iron or glued together, two printed labels were attached together on a single corrugated cardboard at the same time, thereby improving productivity.

The main configuration of the method for adhering the label to the cardboard according to the invention, the step of preparing a label (3); Supplying the prepared label (3) to the paper roll (1) in which the intake hole (2) is formed on the outer surface of the cylinder; Sucking the supplied label paper (3) through the intake hole (2) and attaching it to the outer surface of the paper roll (1); Rotating and conveying the lamination roll 1 to which the label paper 3 is attached; Applying an adhesive to the transferred label paper (3); It characterized in that it comprises the step of laminating the cardboard (10) and the labeling paper (3) coated with an adhesive, wherein the labeling paper (3) is supplied at the same time two sheets to the paper roll (1), the labeling paper (3) The cardboard 10 to be laminated is characterized in that one piece, the labeling paper 3 is characterized in that the label is formed on the UV coating (UV), the labeling paper 3 is characterized in that the printed art paper In addition, the lamination apparatus used in the lamination apparatus for supplying the yube-coated label paper to the lamination roll and the cardboard, the lamination roll (1) is formed in the intake hole (2), the lamination paper supplied Suction attached to the roll (1) to transfer it characterized in that it is configured to be laminated with cardboard.

According to the present invention, it is possible to inexpensively manufacture a large corrugated cardboard box exceeding the limits of conventional offset printing and front lamination with a high-quality color box.

In addition, according to the present invention, by preparing and manufacturing a single-board corrugated cardboard box instead of two sheets of non-standard sheet iron as in the prior art, it is possible to prevent the mixing of two sheets of corrugated cardboard produced separately, there is no defective cardboard box It is possible to complete

In addition, according to the present invention, since the label paper 3 is attached to the roller using inhalation air and transported, the label paper 3 is not pushed or moved in the transfer process by the lamination roll 1, and thus, the corrugated paper to be attached ( 10) can be attached to the exact position of the corrugated cardboard can be reduced as much as possible.

In addition, according to the present invention, because it uses a label coated with a yube can use an adhesive with a small moisture content, and also by partially laminating into one or two sheets, thereby improving the compressive strength of the packaging box.

In addition, since the corrugated cardboard box is manufactured first, the productivity of the corrugated cardboard can be reduced and the manufacturing process can be drastically reduced compared to the conventional two-sheet corrugated fabrics. The reason why the amount of corrugated cardboard can be reduced is that if the two pieces are manufactured to make one packaging box as in the prior art, more parts are cut unnecessarily according to each of the pieces.

In addition, the cardboard box coated with UV coated paper is beautiful in appearance, so that the display advertisement effect of the product is excellent and the quality of the packaged product can be further enhanced.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is explained in full detail based on an accompanying drawing.

1 is a view for explaining the configuration of the apparatus according to the present invention.

As shown, a large number of intake holes 2 are formed in the paper roll 1.

The intake hole 2 is configured to suck in the air of the outside air.

On the other hand, the label sheets 3 stacked on one side of the paper roll 1 are automatically supplied one by one in the direction of the paper roll 1. The label 1 is a label on which a U.V coating is formed.

For example, the label preparation may be performed with high precision printing on art paper having excellent smoothness, and then processed into a UV coating having the best gloss, friction resistance, and waterproofness, and cut in four directions to complete the label preparation. When the UV coated label 3 is used, the surface smoothness and the like are excellent, and the amount of paste to be laminated at the time of lamination to the corrugated cardboard is extremely good at least.

The supplied label paper 3 draws in air through the intake hole 2 of the paper roll 1, and pulls the supplied label paper 3 to the intake air, thereby circulating the paper roll 1 to the paper roll 1 circumference. It is transferred to the right side of the drawing by attaching to. Then, the adhesive is applied by the adhesive roller 7 to the adhesive supply unit 12 and rotates together with the paper roll 1. In the adhesive supply unit 12, an adhesive is accommodated, and the doctor roller 9 receives the adhesive and transfers the adhesive to the adhesive roller 7, and in the doctor blade 5, the adhesive is scraped off so as to properly adjust the amount of adhesive applied. Allow to be applied. The adhesive supply unit 12 is a well-known technique, and is merely shown as an example, and can be configured to control the amount of adhesive applied by various other devices or structures.

The label paper 3 to which the adhesive is applied is laminated with the corrugated cardboard 10 fed one by one below. In the figure, the paper is laminated at the bottom of the paper roll 1, that is, at the paper sheet 32.

FIG. 2 is a diagram showing the ease of understanding on the basis of the operation of FIG. 1 for laminating two sheets of label paper 3 simultaneously on one sheet of large cardboard 10.

As shown, the paper roll 1 is a cylindrical roll whose length is sufficiently long so that two sheets of label paper 3 can be supplied with respect to the length surface 21 thereof. Since the adhesive coating operation and the like after supplying the label paper 3 are the same as those of FIG. 1, illustration thereof is omitted.

Thus, according to the intake of the paper roll 1, since the two sheets of the coated papers 3 and 3 coated with the yuv can be closely supplied and simultaneously supplied, the adhesive is simultaneously adhered to the upper surface of the corrugated cardboard 10 manufactured in a large size. It is possible

For reference, as described above, in the conventional case, the cardboard 10 itself is manufactured in half of the size of FIG. 2, and each piece of label paper 3 is attached to each of the two pieces of corrugated cardboard, and the classification is again performed. The cardboard boxes were joined together to form a large cardboard box.

The reason why the paper roll 1 is sufficiently long and the two large labels 3 can be attached at the same time as in the present invention is that a plurality of intake holes 2 are formed in the paper roll 1, and the label paper 3 is laminated. This is because the roll 1 can be brought into close contact with the intake air sufficiently. In addition, since the label paper 3 is not pushed or moved in the transfer process by the lamination roll 1 due to the transfer by the intake air, it is possible to attach the correct position to the cardboard 10 to be attached.

The label paper 3 may be made into one large sheet as needed, but in this case, since it is attached to a large area with respect to the corrugated cardboard 10, the amount of adhesive applied increases, so that a lot of moisture may enter and deformation may occur. It is superior in all functional aspects such as the strength of corrugated cardboard than the conventional case

As described above, the laminated cardboard 30 having two labels 3 attached to the cardboard 10 enters the next process and undergoes the necessary processing, that is, a partial cutting and iron or adhesive process for making a cardboard box, and the like. Cardboard box is completed

In addition, if necessary, the flexible cardboard box with flexographic printing is first produced in an inline machine, and after completion, the label may be laminated on only one side to improve productivity and reduce cost. The manufactured cardboard box is the same as the known ones that the packaging box is completed only by folding, so the detailed description and configuration thereof will be omitted.
