Description

Corrugated cardboard forming apparatus for wood with increased burst strength and method

The present invention relates to a corrugated cardboard used in various packaging, in particular, because the use of recycled paper as the main raw material in consideration of the characteristics of the corrugated cardboard relatively vulnerable to the impact strength, the upper and lower adhered to the center around the core core located in the center Corrugated cardboard forming apparatus and method for replacing wood by coating another surface protection sheet on the outside of the surface paper so as to be used as a wood replacement means by remarkably improving the bursting strength as well as the vertical compressive strength of the cardboard will be.

Generally, in order to pack glass products such as cosmetics, which are relatively durable, electronic products vulnerable to impact resistance, such as TVs, and other items that require considerable attention to handling, they absorb a shock delivered to the box together with a rigid box. There has been an urgent need for the use of auxiliary cushioning materials to give.

Such cushioning auxiliary materials include styrofoam molded in the form of articles or corrugated boards configured to be fixed by folding or cutting them in a certain form. In the case of a package having a heavy weight such as a refrigerator, external impact Along with the cushioning resistance, durability to support the weight with sufficient force is also required, and wooden pallets are widely used.

In addition, in the near future, instead of expensive natural pulp or wood, which is almost entirely dependent on imports, the recycling and recycling movement using waste resources is actively carried out in the environment of raw material supply and the environmental protection. Although the strength is somewhat reduced by the use of waste resources, corrugated materials, which have both durability and cushioning properties, are used in various forms in a wide range of fields.

Such a corrugated material, while maintaining excellent buffering properties and stable vertical compressive strength, has a large density of tissues, so that the perforated strength is generally very weak.

Therefore, as a way to compensate for this weakness of the corrugated material, in the case of a box for packaging an advanced product such as a special product, a separate manila cardboard (SC cardboard) printed by offset printing is laminated on the surface of the corrugated cardboard. In some cases, a method of reinforcing the thickness of the surface sheet may be used. However, this also involves the process of laminating the smooth liner on one side of the molded corrugated sheet, which makes the process difficult and makes mass production impossible due to the multi-process production method, and the production cost is also increased significantly. Various problems are shown.

The above problems are also never solved simply by simply reinforcing the thickness of the corrugated liner. This is because, when using a thick liner to increase the burst strength of the corrugated cardboard, the workability of the corrugated material is very poor due to the increase in weight. This is because the production is showing a problem that is significantly reduced.

The present invention has been proposed in order to solve such a conventional problem, to provide a corrugated material of improved structure that can be usefully used as a wood replacement means by significantly improving the burst strength in addition to the vertical compressive strength of the cardboard Is there.

Particularly, the present invention is to coat each other with another surface protection liner overlapping the outer surface of the upper and lower surface paper bonded to the outer center around the core core located in the center, the liner coating operation is sequentially performed by a series of processes for forming the cardboard Its main purpose is to enable automated production.

Another object of the present invention is to allow such a high value-added corrugated material to greatly contribute to the reduction of production costs through the process of mass production.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall process diagram schematically illustrating a corrugated sheet forming process of the present invention, the corrugated material forming apparatus of the present invention, as shown, heats two liners 11, 12 wound in a roll state The back liner lamination means 100 which is laminated is provided.

Such a back liner lamination means 100 is a thing which continuously laminates two liners 11 and 12 respectively supplied from the liner winding rolls 110 and 120 provided in the left and right sides, and guider 101 and 102. A pair of guide tension rolls 103 and 104 are provided on both left and right sides so that each liner 11 and 12 supplied through the (1) can be guided in a fully unfolded state.

And the press roll 105 composed of a pair of upper and lower pairs so that the liners 11 and 12 continuously guided through these guide tension rolls 103 and 104 can be laminated while facing each other in a sufficiently supported state. ) And a heating lamination roll 106, and an inner liner 11 supplied to surround the heating lamination roll 106 and an outer liner 12 supplied to be laminated thereon from above. The press press belts 107 are installed adjacent to each other so that their adhesion can be made more efficiently by tightly touching them.

The pressing press belt 107 is installed in a form surrounding a portion of the upper side of the heating paper roll 106, which is sufficiently supported by a pair of drive rolls 108 are spaced left and right, the heating paper On one side of the roll 106, by applying a certain amount of adhesive to the surface of the back inner liner 11 which is guided around the heating paper roll 106, the back outer liner 12 laminated thereon can be stably bonded to each other. Adhesive application means 130 is laid so that.

Such adhesive applying means 130, as shown in Figure 2, the structure of the transfer roller 132 is installed in the adhesive storage tank 131 adjacent to the inner liner 11, so as to immerse it in the storage tank It may be desirable to configure the adhesive 20 enclosed in 131 to be quickly transferred to the liner 11 through the transfer roller 132 for applying the adhesive.

In the transfer roller 132 for applying the adhesive, the adhesive 20 may be accommodated in a predetermined thickness so that the halftone transition of the adhesive 20 is possible on the surface of the liner 11, as shown in FIG. 3. The adhesive liquid receiving hole 134 is continuously molded to a predetermined depth.

In configuring the adhesive applying means 130, a separate dipping roller 133 is immersed in the adhesive storage tank 131, and a transition roller 132 for applying the adhesive is installed in contact with the dipping roller 133. It is also possible to configure the adhesive 20 supplied through the transition roller 132 to the surface of the liner 11 to be applied with a uniform and constant thickness.

The inner liner 11 guided through the lower tension roll 103 is a heating lamination roll which is installed in contact with the press roll 105 of the liner lamination means 100 and an upper side thereof, as shown in FIG. 2. 106).

The inner liner 11 guided between the press roll 105 and the heating lamination roll 106 is also guided to surround the heating lamination roll 106 and is installed outside the heating lamination roll 106. Since the appropriate amount of adhesive 20 is uniformly applied to the exposed surface by the adhesive applying means 130, the press provided on the upper side along with another liner 12 guided through the tension roll 104 on the other side When passing through the belt 107, a firm adhesion is achieved.

To this end, the heat-resistant film 116 is coated on the surface of the heating lamination roll 106 so as to stably maintain the feeding speed of the liner 11 to be supplied. In the outer circumference of the heating lamination roll 106, a plurality of air adsorption holes 112 are also drilled, and inside the heating lamination roll 106, air may be adsorbed or ejected through the adsorption holes 112. Two air nozzles 114 are installed with different intervals so as to be installed.

That is, the inner liner 11 of the two back liners 11 and 12 continuously supplied to the liner laminating means 100 passes through the heating lamination roll 106 before and after the adhesive coating section. It is in close contact with the roll surface by air adsorption of the adsorption hole 112 perforated on the outer periphery of the), out of the adhesive application section to the section to be guided to the press belt 107 to the heating lamination roll 106 Air adsorption of the perforated adsorption hole 112 is converted to air ejection to maintain the press pressure to the maximum.

In this case, as the adhesive 20 applied to the contact surfaces of the liners 11 and 12, a starch-based adhesive that generates adhesive strength while ripening starch grains may be usefully used. This is because it has a gelatinization temperature of 60 to 120 ℃, it is inconvenient to use it as an adhesive because it has a very high viscosity at low concentration in the state of heating and decomposition, while fluidity is very excellent in the state of unheated starch mixture, such starch This is because the adhesive also has the advantage of being sufficiently luxurious to exhibit strong adhesive force when appropriate heat is applied in the process of laminating the two liners.

It is not preferable that the adhesive 20 applied to the contact surfaces of the liners 11 and 12 form a continuous coating film with a uniform thickness. Since the adhesive 20 applied between the two liners 11 and 12 is to be kept closed by the liners 11 and 12, it takes a long time to dry, and thus is not sufficiently dried. When the heat lamination roll 106 is left in an unsatisfactory state, the undried adhesive liquid existing between the two liners 11 and 12 causes a single layer movement of the liner, and thus the laminated liner 13 is bridged. This is because it is difficult to maintain the smoothness of the product by bringing the closed end dried in the bent state when passing (124), which can act as a serious defect of the product.

Therefore, in order to allow sufficient drying in the minimum drying section, the adhesive 20 applied to the bonding surface of the paper liner 13 should be uniformly applied to an appropriate size to form a dot, and through such a dot gap In addition, as shown in FIG. 4, the lattice-shaped water passage 22 may be secured in the adhesive surface of the laminated liner 13 so that the air permeability may be maintained.

In front of such liner liner lamination means 100, a preheating means 122 is provided to be provided so that the liner 12 supplied can be preheated to a sufficient temperature for adhesion. On the output side of the liner laminating means 100 having the 110 and 120, the single-sided corrugated cardboard 15 is formed by attaching a corrugated core 15 having a predetermined wave on the upper side of the laminated back liner 13. 17 is provided with a one-sided corrugated cardboard forming apparatus 200 to provide.

The one-sided corrugated cardboard forming apparatus 200, as shown through the structure of the corrugator forming the corrugated cardboard getter shown in Figure 5 for guiding the corrugated liner 14 to form a predetermined wave for the upper and lower pairs of bone forming Roller 205 and 206, and the adhesive applying roller 232 for uniformly applying the adhesive 20 to the surface of the core core 15, which is laid and processed on one side of the upper bone forming roller 206, and the Of the bone forming rollers 205 and 206 to pass the pair of bone forming rollers 205 and 206 to closely contact the corrugated core 15 having a wave formed therein and the paper liner 13 supplied from the other side. The laminated liner 13, which is composed of a press belt 207 and a belt driving roll 208 installed on the upper side, is supplied to the pair of roller forming rollers 205 and 206 for speed adjustment. Supporting the acceleration roll 203 and the guide tension roll 204, respectively. It is configured to me.

The bone forming rollers 205 and 206 for forming a predetermined wave on the guided corrugated liner 14 are formed in a pair of upper and lower structures which are arranged so as to continuously form a regular and various curvature. By installing a plurality of adsorption holes (not shown) along the groove of the roller on the surface of the roller forming roller 206, the corrugated core 15 to be bonded to the laminated liner 13 is a bone forming roller 205 ( It is configured to maintain a desired wave in close contact with the curved surface of the upper roller 206 by air adsorption through the adsorption holes when passing between the 206.

In other words, the adsorption hole damages the shape of the bone until the moment when the corrugated core 15 forming the desired wave meets the lamination liner 13 while passing between the bone forming rollers 205 and 206. In order to maintain the same as it is, the adsorption force is removed when the corrugated medium 15 reaches the position where it is in contact with the liner 13 guided along the surface of the press belt 207, which It can be seen that the structure of the heating lamination roll 106 and the roller surface of the above-described liner lamination means 100 are different from each other, and take the same structure.

The bone forming rollers 205 and 206 for processing the corrugated liner 14 supplied from the corrugated liner supply roll 140 to a predetermined pitch and height are preferably installed as replaceable cartridges. However, this is to enable the desired work through the exchange of some of the configuration of the liner laminating means (100). That is, the one-sided corrugated cardboard forming means 200 can be dedicated to its role and function through the replacement of the rollers 105 and 106 provided in the cartridge type as compared with the above-described configuration of the liner laminating means 100. To construct.

On the other hand, the adhesive coating roller 232 which is attached to one side of the upper bone forming roller 206 to uniformly apply the adhesive 20 to the surface of the bone core 15, the core core (in the adhesive storage tank 231) It takes the structure of transition roller which is installed adjacent to 14).

In front of such single-sided corrugated sheet forming means 200, similar to the surface paper 12 guided by the liner laminating means 100, the lamination liner 13 supplied to pass through the preheating means 222 is required for adhesion. It is configured to be preheated.

The single-sided corrugated cardboard 17 and each of the surface liners 18 and 19 are supplied between the hot plate 410 and the pressure belt 420 and pressurized at a constant pressure to form a high-quality corrugated material required by the present invention. will be.

According to the present invention configured as described above, first, the two liners 11 and 12 are respectively supplied from the left and right liner supply rolls 110 and 120 using the liner laminating means 100 installed on the outermost side. Continuous bonding with a smooth sheet of laminated liner 13, but the adhesive 20 is bonded to their adhesive surface to form a solid liner (13) that retains breathability by adhering.

And this is to pass through the press belt 107 is installed in a form surrounding the pair of belt drive roll 108 consisting of two left and right, so that the lower portion of the belt to sufficiently press the upper surface of the heating lamination roll 106 It is possible to effectively prevent the formation of the press roll mark on the surface of the liner 13 to be molded.

In this case, the innermost liner 12 of the two back liners 11 and 12 supplied to the heating and laminating means 100 may be selectively used for heterogeneous sheets in consideration of moistureproof and insulation functions. will be.

Then, the laminated liner 13, which is to be bonded to the two liners 11 and 12, is supplied to the single-sided corrugated cardboard forming means 200, and the corrugated cores 15 are stacked on the single-sided corrugated cardboard 17 so as to overlap the single-sided corrugated cardboard 17. Processing.

The one-sided corrugated cardboard 17 to which the corrugated cardboard 15 is bonded is guided to the tapered guide 300 so that the supply speed of the corrugated cardboard can be controlled, and the single-sided corrugated cardboard 17 continuously supplied has a constant tension. At the same time, the tension roll 310 and the preheating means 320 are passed to sufficiently preheat these surfaces.

The lower end of the single-sided corrugated cardboard 17, which is supplied via the paper guide 300, is to supply the liners 18 and 19 parallel to the surface of the corrugated material again, and the core end portion of the single-sided corrugated cardboard 17 to be guided and After a certain amount of adhesive is continuously applied on the opposite side of the corrugated end of the liner 18 supplied inside, the single-sided corrugated cardboard 17 and the liners 18 and 19 to which the adhesive is applied are transferred to the hot plate 410.
