Description

[0001] The present invention relates to a packing adhesive of a pressing device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressing apparatus for a packaging box bonding machine in which a packing box on which an adhesive is applied is conveyed to a conveyor, So that the adhesive can be adhered to the surface of the packaging box without leaving a mark on the surface of the packaging box.

Generally, the packaging box is manufactured by using automation equipment. The process of manufacturing the packaging box includes a process of printing a pattern or stationery on the surface of raw paper, a process of coating the surface of raw paper, a packaging box A step of cutting the original paper in accordance with the developed view of the original, and a step of bending and bonding the cut original paper.

In the process described above, a bonding machine is used for bending and bonding the cut paper.

The bonding machine comprises a feeding device for automatically feeding the paper, a coating device for applying the adhesive, a folding device for folding the paper, a pressing device for pressing the folded packing box, and the like. The processes such as adhesive application, bending, pressing, and stacking are sequentially and automatically carried out, and the packaging box is manufactured through an automated line.

The pressing device of the adhesive machine presses the folded upper and lower sides of the folded paper in a state where the adhesive is applied to the adhesive surface of the paper, so that the bonding partner of the packaging box has a firm bonding force. In order to increase the compressive strength, press it with high pressure.

In particular, packaging boxes used for packaging of expensive electronic products or cosmetic products where aesthetics are important are made of high-quality paper, and since the high-quality paper is made of a high-grade coating on the surface thereof, adhesion by the adhesive is not properly performed. Because various printing techniques are used to prevent the surface of the packaging box from being damaged or discolored, many kinds of paints are applied, which prevents them from adhering to the surface of the packaging box. .

In addition, when the packing boxes are individually pressed in the pressing apparatus, productivity is lowered. Therefore, when a certain unit (for example, 10 sheets) is collected, the sensor recognizes and transports them to the conveyor while a plurality of packing boxes are stacked Thereby enabling mass production.

However, in this case, when the upper and lower portions are pressed in a state in which a plurality of boxes are stacked, a pressed mark is generated on the surface of the box while being adhered to each other by the adhesion surfaces of the adjacent boxes. Especially, in the case of high-quality paper, pressing force is required to be pressed with a strong pressure, so that the pressing mark is more clearly generated, which significantly reduces the product value of the packaging box using high-quality paper.

In addition, if marks are formed on the surface of the packaging box, it is determined to be defective and a loss is incurred, and the amount of waste due to defective appearance is considerably increased in packaging the product using the packaging box.

In addition, a cylinder for adjusting the compressive strength is mounted on the lower end of the conveyor of the pressing apparatus so that the roller has a compressive strength. If the compressive strength of the roller is lower than the reference pressure, In this case, it is necessary to apply pressure to the box located at the upper and lower part of the stacked box, where the pressure is directly transmitted by the conveyor, As a result, pressing marks are formed on the surface of the box.

Therefore, in the case of adhering high-quality paper on the spot, most of the pressing force of the pressing device is subtracted from the pressure of the pressing device, so that the packaging box is pressed by the upper and lower intervals of the conveyor.

However, this results in poor adhesion of the packaging box and eventually leads to product defects.

The buffering means 130 and 230 padded to the belts 120 and 220 are for pressurizing the packaging box, more specifically, for pressing the folded portion after the adhesive is applied in the packaging box, The sponge pads 132 and 232 having high elastic modulus can be attached and attached.

The sponge pads 132 and 232 can uniformly distribute the pressure while buffering the packing box by using a material having a relatively higher elastic modulus than the elastic modulus of the belts 120 and 220, The width of the elastic deformation caused by the pressure can be increased by making the thickness of the belt 120 relatively thicker than the thickness of the belts 120 and 220.

The buffering means 130 and 230 may be configured such that the thickness of the sponge pad 132 padded on the belt 120 of the first conveyor 100 and the thickness of the sponge pad 232 padded on the belt 220 of the second conveyor 200 are So that the pressure transmitted from the first conveyor 100 and the second conveyor 200 to the upper and lower portions of the packaging box is transmitted at the same pressure.

The buffering means 130 and 230 may be formed to have the same width as that of the belts 120 and 220 mounted on the respective conveyors or may be formed only with a part of the entire width of the belts 120 and 220.

The buffering means 230 mounted on the second conveyor may be composed of a plurality of units so as to increase the compatibility with the size of the workpiece corresponding to the standard of the packaging box.

The pressing apparatus of the packaging box binder of the present invention further comprises a pressing device 300 for adjusting the compressive strength of the packing box by adjusting the widths of the upper and lower spaces of the spaces between the first conveyor 100 and the second conveyor 200 And the like.

The pressurizing device 300 is configured such that the cylinder device 310 is connected to the roller 110 of the first conveyor 100 to pull the belt 120 upwardly and the cylinder device 310 is constituted of a plurality of It is possible to apply a pressing force to the belt 120 by pulling the arranged rollers 110 upward.

The cylinder device 310 can adjust the pressure by the operation of the controller, so that the compression strength of the packaging box can be set, and the compression strength can be set differently according to the quantity of the packaging box to be stacked or the thickness of the packaging box.

The compressive strength can be changed according to the time taken out through the space between the first conveyor 100 and the second conveyor 200. For example, when the conveying length of the conveyor is shortened or the rotation speed of the conveyor is increased The compression strength can be relatively increased, so that the packaging box can be bonded with a strong pressure.

The inlet unit 400 may further include an inlet unit 400 in which the first conveyor 100 and the second conveyor 200 face each other.

The dispenser 400 senses the quantity of the folded material after the adhesive is applied to the raw paper for making the packaging box, and when the dispenser 400 reaches the set quantity, the dispenser 400 is operated, 2 conveyor 200 can be inserted into the space.

The buffering means 130 mounted on the first conveyor 100 may further include a tension adjusting means 134.

The tension adjusting means 134 is caused to perform the path guidance by the plurality of auxiliary rollers 134a so that the sponge pad 132 is branched from the belt 120 of the first conveyor 100. [

The auxiliary roller 134a may be constituted by one or more rollers. When the auxiliary roller 134a is constituted by one roller, the tension of the buffer means 130 can be adjusted by varying the position of the auxiliary roller 134a itself, When a plurality of auxiliary rollers 134a are formed as shown in FIG. 10, the position of the other one of the auxiliary rollers 134a is changed with one of the auxiliary rollers 134a as a basic axis, It is possible to adjust the tension of the belt.

The tension adjusting means 134 is mounted on the auxiliary roller 134a so as to support both ends of the lift means 230 and the guide disc 134b is detachably assembled and supported on the auxiliary roller 134a The position of the guide disk 134b can be varied.

The second conveyor 200 is preferably configured such that the sponge pads 232 are formed with only a part of the width of the entire belt 220. The sponge pads 232 can be adjusted by the position adjusting means 234 .

The position adjustment means 234 is disposed at a position where the first conveyor 100 and the second conveyor 200 are opposed to each other and the packing box is put in close proximity to the charging device 400 so that the position of the sponge pad 232 is arbitrarily set The conveyor can be operated in a state in which the adhesive surface of the stacked packaging box is accurately brought into close contact with the sponge pad 232 of the second conveyor 200 while being prevented from moving.

Hereinafter, the operation and effect of the pressing apparatus of the packaging box binder according to the present invention will be described in detail.

First, the pressing device of the packaging machine of the packing box presses the adhesive to be applied to the raw paper after folding and then presses it at a certain pressure to attach the packaging box. When the packing box supplied to the pressing device is accumulated in a certain quantity, And is introduced into the spacing space between the first conveyor 100 and the second conveyor 200 by the putter 400 positioned therein.

The packing box inserted into the spacing space between the first conveyor 100 and the second conveyor 200 is conveyed along the belt 120 by the driving force of the first conveyor 100 located at the lower part, The second conveyor 200 is pressed to press the upper part of the packed box, and the packed box is compressed with the set compressive strength.

Since the buffering means 130 and 230 are composed of the sponge pads 132 and 232 having high elastic modulus, the shape of the sponge pads 132 and 232 is deformed between the stacked packing box and the belt so that the pressure deviation is corrected. Dispersed evenly.

At this time, the thicknesses of the sponge pads 132 and 232 mounted on the first conveyor 100 and the second conveyor 200 are made equal to each other, so that the pressure is prevented from leaning upward or downward, Can be uniformly delivered to the packaging box.

The buffering means 130 and 230 attached to the first conveyor 100 and the second conveyor 200 can be formed at a low cost by forming the sponge pad 232 only at a part of the width of the entire belt 220, In addition, it is possible to selectively press only a portion to be compressed so that bonding can be performed.

Therefore, by concentrating the portion of the stacked packaging box where the adhesive surface is formed, pressure can not be dispersed throughout the packaging box, so that the adhesive surface can be pressed with a stronger force, and the packaging box is more closely adhered.

At this time, the sponge pad 232 is continuously rotated together with the belt 220 of the second conveyor 200 while the sponge pad 232 is fixed in position by the position adjusting means 234, The adjusting means 234 can maintain the mounting position of the sponge pad 232 as it is.

In addition, since the buffering means 230 is composed of a plurality of packing boxes, it is possible to increase the compatibility with the sizes of the workpieces in accordance with the specifications of the various packing boxes, so that it is not necessary to re- .

When the tension of the sponge pad 132 is loosened or excessively tensioned by using the tension adjusting means 134 formed on the buffering means 130 of the first conveyor 100, The tension of the sponge pad 132 can be easily adjusted by changing the position of the auxiliary roller 134a.

The buffer means 130 attached to the belt 120 of the first conveyor 100 may be formed only in a part of the width of the entire belt 120 corresponding to the width of the packaging box. The sponge pad 132 is supported at both ends by the guide disk 134b mounted on the auxiliary roller 134a so that the sponge pad 132 can be stably rotated along with the belt 120 .

When the guide disk 134b assembled to the auxiliary roller 134a is separated, the position of the buffering means 130 can be adjusted. After the position of the buffering means 130 is reset, the guide disk 134b The auxiliary roller 134a of the tension adjusting means 134 may be changed in position so that the tension of the sponge pad 132 is loosened, It is preferable to move the mounting position of the arm 132.

Accordingly, since the position of the buffering means 130 can be easily shifted as needed, the utilization efficiency is further increased. Further, the buffering means 130 is divided into two lines in a single pressing apparatus so as to perform a pressing operation It is possible.
