The present invention relates to a packaging cushioning material used in a variety of packaging, in particular, after repeatedly cutting the incision groove in the longitudinal direction on the surface of the cardboard having a constant angle bending process so that these incisions protrude to a constant height with respect to the vertical direction The surface protection sheet is laminated on the surface to maintain shape and soft surface, and absorbs the shock from the outside to the package effectively, and has a buffer effect to keep the packaged contents safer. An improved high strength buffer sheet forming apparatus and method are provided.

In general, shocks transmitted in a box together with a rigid box are used to package glass products having relatively low durability such as expensive cosmetics, electronic products vulnerable to shock resistance such as TVs, and other items requiring considerable care in handling. There has been an urgent need for the use of auxiliary buffer materials to absorb these.

Such cushioning auxiliary materials are mainly composed of styropoles molded in the form of articles or earths configured to be fixed or folded in a fixed form.

However, in the case of the cushion material formed of styropol, its use is gradually avoided despite the advantages of easy molding and mass production, which causes static electricity along with a problem that some of the packaging materials are easily damaged and contaminate the surroundings. It is not used for the packaging of products that must maintain precision, and furthermore, it shows a disintegration that shortens the life of the product, and thus is only limited to a limited field.

On the other hand, the cushioning material formed by folding the paper into a certain form may cause side effects such as mass production is impossible, durability is weak, and a stake occurs during assembly to affect the life of the product.

Therefore, in recent years, a packaging material that forms a package case using a pulp mold has been developed and used. However, even if a small amount is produced, a separate individual mold is required, and thus requires a skilled technique. In addition to difficulties in manufacturing, manufacturing costs are rising.

In addition, in recent years, as the importance of environmental preservation is recognized, much attention has been focused on the processing of used packaging materials. This means that packaging materials using Schiropol or plastic cannot be recycled, and the separation work is cumbersome and discarded. This is because it causes serious natural ecosystem destruction along with pollution. Due to such factors, the necessity of nature preservation is increasing day by day, and the demand of many kinds of packaging materials, which are made of materials that cause environmental pollution, such as synthetic resins, is gradually decreasing, especially for some interested consumers.

It is a longitudinal cross-sectional view.

The packaging shock absorber molding apparatus of the present invention includes a paper sheet supply device 10 that continuously supplies the corrugated sheet paper 50 wound on the collected cardboard or roll in one direction.

The paper sheet 50 supplied through the paper sheet supplying device 10 is smoothly unfolded to be guided to the processing unit side so that the paper sheet 50 can be cut to the desired width of the product. The width cutting cutter 12 is installed on one side.

The base paper 50 cut to a predetermined width while passing through the width cutting cutter 12 has a cut groove formed to cut the cut grooves 52 at regular intervals on the cut paper 50 again. Pass through the cutter 14, the cutter 14 for forming the incision grooves are to be controlled to hold a plurality of blades 15 to drive up and down independently.

In other words, the blades 15 are arranged at regular intervals in the cutter support 16 installed at a position orthogonal to the direction in which the paper is fed, and these are independent drive means 17 so that the vertical movement can be freely performed. For example, the hydraulic cylinder (pneumatic) to hold the cylinder, such a driving means 17, the operation time is each through a separate numerical control device according to the position and size of the cut groove 52 to be processed on the paper 50 To be determined.

However, the base paper 50 cut in the longitudinal direction by the cutting groove forming cutter 14 as illustrated in FIG. 3 is spaced apart from each other by the respective cutting grooves 52 so as not to be separated from each other. It is required to form the cutout portion 53 having a relatively short length. This short cut 53 is to play an important role in maintaining the strength and durability of the corrugated base paper (50).

The base paper 50 which has passed through the cut groove forming cutter 14 is supplied between the pair of wave forming rollers 18 which regularly protrude the ridge 19 on the surface.

The base paper 50 supplied in this way continues the wave having a predetermined height while the cut portion 52 is pressed by the ridge 19 while passing through the wave-forming roller 18 having a pair of upper and lower structures. Will be bent.

Such a cutting groove forming cutter 14 may be configured integrally with the wave forming roller 18 protruding the ridge 19 so that the desired cutting portion may be formed at the same time during wave processing.

That is, by supplying the supplied paper 50 to the wave-forming roller 18 having a pair of upper and lower structures, predetermined cutouts 52 may be formed prior to wave formation by the roller ridge 19. The wave may be formed as a structure in which the wave repeatedly crosses up and down along the cutout 52.

The wave forming roller 18 is a pair of unit assemblies having different heights of the protrusions, and when configured to form a cassette, the wave forming roller 18 may be easily replaced according to the shape and size of the wave formed on the workpiece. . The height of the wave to be processed on the base paper 50 can be adjusted according to the weight or strength of the packaged contents, the height adjusting guider 20 on the output side of the wave forming roller 18 so that the height of the wave can be arbitrarily adjusted. ) Are installed adjacent to each other.

The height adjusting guider 20 presses waves formed at a tight interval through the wave forming rollers 18 at a predetermined pressure on both upper and lower sides to distribute the density horizontally, which is processed paper 50 Will have a direct impact on the durability and cushioning of

In this way, the wave is formed on the base paper 50 to maintain the desired height, and then the surface protection sheets 61 and 62 can be softly finished on the upper and lower surfaces of the base paper 50 at the same time. )).

The sheets 61 and 62, which are partially bonded to upper and lower surfaces of the base paper 50 having a predetermined wave to protect the surface of the package, are installed in a section supplied from the sheet winding roller 22 to form a sheet ( 61, 62 is subjected to an adhesive applying device 24 for applying a certain amount of adhesive on.

The adhesive waveguide device 24 for applying a certain amount of adhesive on the product surface protection sheets 61 and 62 is formed in the adhesive storage tank 25 and the sheets 61 and 62 as shown in FIG. By immersing the transition rollers 26 installed adjacent to each other, it is desirable to configure the adhesive contained in the storage tank 25 so that the adhesives can be quickly transferred to the sheets 61 and 62 through the transition rollers 26. will be.

However, in configuring the adhesive applying device 24, the nozzle is configured to arrange a plurality of nozzles in a row but selectively open only a part of the nozzles according to the shape of the workpiece so as to arbitrarily adjust the width and range of the applied adhesive. It is a plate-type structure of an attachment type, or a separate immersion roller (not shown) is immersed in the adhesive storage tank 25, and a transition roller 26 is installed in contact with the immersion roller to provide a transition roller on the surface of the base 50. It will also be possible to configure the adhesive supplied via 26 to be applied at a uniform and uniform thickness.

As described above, the surface protective sheets 61 and 62 and the base paper 50 coated with the adhesive are configured to pass through a pair of ground rollers 28 provided in both the upper and lower directions of the processed paper 51. In this configuration, the sheets 61 and 62 and the base paper 50 are sufficiently pressurized by the ground roller 28 to exhibit a firm adhesive state.

The ground roller 28 is installed in conjunction with the height adjusting guider 20 so that the distance of the position of the guider 20 is variable.

The processing base 51 which grounds a pair of upper and lower surface protection sheets 61 and 62, respectively, may further include a curvature molding machine 30 provided outside the ground roller 28 so as to maintain a predetermined curvature. Passing through the drying device 32, which is installed on the output side to quickly dry the bent portion in order to prevent the sheets 61 and 62 from being separated during transportation, and cutting these continuous molded semi-finished products 34 As a result, a high-strength buffer sheet having excellent durability is completed through a process of cutting to a predetermined length.

According to the present invention constituted as described above, first, the recycled cardboard or the corrugated cardboard 50 wound in a rolled state is supplied through the paper supply device 10.

Thus, the supplied paper 50 is inserted into the width cutting cutter 12 and cut to a predetermined width in accordance with the specification of the product to be molded, and then the cut paper 50 is cut to form the cut groove 14. It is to be processed so that the cutting groove 52 of a constant interval on the surface by using a continuous cut.

It is also possible to perforate the article inserting portion 58 so that the projecting portion of the package can be fitted on the sheet of paper 50 during the processing of the cut groove 52, the post-processing of the sheet of paper 50 during the processing of the article inserting portion 58 In consideration of the folding in the longitudinal direction according to the pressing the size of the insert somewhat relaxed.

After the cutting is completed as described above, the cut groove 52 passes through the processed paper 50 between the pair of wave-forming rollers 18 in which the ridges 19 protrude from the surface.

The base paper 50 supplied between the wave-forming rollers 18 is bent by the ridges 19 of the rollers 18 to be divided by the respective cutting grooves 52. 50) can be repeatedly formed to cross the wave having a predetermined height in the vertical direction.

After the wave molding, the base 50 formed with the wave is passed through the height adjusting guider 20 in order to adjust the height of the wave formed on the base 50.

The height of the wave adjusted by the height adjusting guider 20 may be expressed as the density of the wave with respect to the unit length. When the height of the wave is lowered, the gap of the wave is loosened, so that the shock absorbency is somewhat lowered, but is suitable for storing lightweight items. When the wave is made high, the spacing of the wave becomes dense, so that excellent buffering property can be secured, so that heavy items can be effectively and safely stored.

The density of the wave can be selectively determined according to the characteristics of the packaged article, which can be usefully used to provide various elastic buffer pads.

After determining the density of the wave as described above, the sheet fixing sheet 61 and the product fixing sheet 61 (coated with the adhesive guided through a separate feeder on the upper and lower sides of the base paper 50 on which the predetermined wave is formed) ( Ground 62) separately.

Since the surface protection sheets 61 and 62 grounded on the base paper 50 are selectively bonded to the tip of the wave processed on the base paper 50, the upper and lower sheets 61 and 62 eventually prevent the deformation of the wave. At the same time, the desired elastic space formed between the wave and the sheet is preserved so that it can be maintained continuously.

In addition, if the high-strength buffer sheet formed as described above is to be processed in a desired curved shape to use for corner protection, the processing base 51 grounding a pair of surface protection sheets 61 and 62 may be used as a curvature forming section. Guide them so that the grounded paper can be shaped into a curved shape.

The processing base 51 with a pair of sheets 61 and 62 grounded in this way is rapidly dried to undergo a drying process after curvature so that the adhesive portion can be firmly maintained. It is possible to provide inexpensively various buffer pads 60 of various types having a predetermined cushioning space 57 on the inner surface by cutting with a zoom.

In the above embodiment, as a preferred embodiment of the present invention, a structure in which the wave-shaped elastic space processed on the base paper 50 is illustrated and described as a single layer can be used for preservation of a small article having a relatively high impact resistance. As another embodiment of the present invention, as shown in FIG. 6 (b), a wave is formed at a predetermined height on the processing base 51 to which the pair of sheets 61 and 62 is grounded. Of course, it is also possible to stack the other processing paper 51a and the upper sheet 65 so that the buffering force is doubled.

At this time, the upper sheet (61, 65) that is adhesively fixed on the processing paper (51) (52a), the article size of the size that can cover the article inserting portion 58 that is selectively punched in the processing paper (51) (51a) By installing the fixed groove 64, the article can be more securely supported by the cut article fixing groove 64 cut.

In addition, the embodiments of the present invention, in addition to the above-described embodiments, can be expressed in various forms that are not enough to achieve the objects of the present invention within the scope of the technical spirit without departing from the scope of the claims to be described later. .

As described in detail through the above embodiments, the incision grooves are repeatedly cut in the longitudinal direction on the surface of the base paper having a certain strength, but these incisions are bent to protrude to a constant height with respect to the up and down direction, and the shape is fixed on the surface.
