The present invention relates to a method for manufacturing a paper angle and a chanel based on paper, and a device thereof, and particularly, in the manufacture of a paper angle and a chanel using an inexpensive sodium silicate as an adhesive, which is very slow to set. It provides a technology that can produce a large amount of paper angle at high speed while preventing the right angled paper angles from bending or deforming to a circular shape, thereby reducing the defect rate during manufacturing, and in particular, it is inexpensive and condensation. Manufacturing method of paper angle and chanel made of soda silicate adhesive which can reduce cost and improve production by increasing mass production at high speed by using slow soda silicate as adhesive and To provide the device.

In general, angles are used as corner members for packaging. Conventional angles are made of metal such as iron, wood, aluminum, or synthetic resin, and the manufacturing method is extrusion molding or sheet metal bending. It has been developed for the purpose, but wood is also suitable for the frame material that fits well with a wooden box or paper box.

However, the wood frame is not expensive because of the scarcity of materials and the manufacturing process is difficult to meet the variety of modern packaging technology, because there is no standard product made of angle materials, and the wood frame is connected to the reasons for preventing environmental pollution during disposal Due to the inconvenience of having to perform a separate operation of separating the metal material, there is an urgent need for the development of a substitute for the wood frame.

Therefore, the environmentally friendly, easy-to-use and easy-to-use papermaking angle developed in accordance with the above requirements and its apparatus have been used in the prior art, and as an embodiment, Japanese Patent Publication No. 59-31453 (1984.08.02) As can be seen also in the supply step 10 (not shown) for supplying a plurality of winding paper, and the immersion for immersing the adhesive liquid of the waterproof liquid tank 3 in the winding paper (1) supplied by the supply process 10 The process 20 is carried out.

After the immersion process 20 is carried out as described above, the immersion process (30) through the lamination process 30 to form a paper (2) by matching the immersed, the lamination process 30 is shown in FIG. As described above, after the plurality of sheets of paper 1 are matched by a guide in multiple stages, each of the sheets of paper 1 is bent by 90 ° to perform a bending process 40 having a cross-sectional shape as an angle 4. After the multi-stage lamination process 30 and the bending process 40 are performed, as the angle 4 is formed, the pressing process 50 to press both sides of the bent angle 4 is performed.

Therefore, the lamination process 30 performs the bending step 40 and the pressing step 50 for each lamination step and the lamination step 30-1, 30-2 and 30-3 of the multi-step lamination process. Press the angle 4 to form a finished product as a complete angle.

In addition, by applying the conventional technique described above, mass production was achieved by the conventional technique in which a heating drying step or a cutting step is added.

However, the conventional paper angle is a problem that increases the cost of production by using expensive water-soluble vinyl acetate resin, PVA, sodium nitrate, urea resin, meta-face resin, acrylic adhesive, modified starch, etc. as an adhesive. In order to reduce the production cost, when the paper angle is produced by the conventional manufacturing method using an inexpensive adhesive, for example, an adhesive based on soda silicate, the right angle of the paper angle is completed. As this time progresses, it becomes gradually obtuse, and it does not maintain the roundness of the right angle, and deforms or bends, resulting in a problem of increasing the defective rate and degrading the merchandise.To overcome this, a low speed of 1-2M (meter) per minute Since paper angles must be produced, it is impossible to achieve mass production, which causes another problem of reduced productivity. Let's go.

The present invention devised to solve the above problems is possible to produce a high speed even at the same time using a low-speed but low-agglomerate adhesive, such as an adhesive based on soda silicate, and at the same time complete the paper angle at a right angle After molding, it is possible to preserve the original form without deforming or bending it at an obtuse angle, thereby ultimately reducing production costs, minimizing defect rate, and supplying cheaper paper angles to consumers. Serve the purpose of doing so.

In order to achieve the above object, the present invention may include a rapid cooling process that allows the non-condensing adhesive of the paper-angle angle cut to a predetermined length by the cutting process and at the same time to rapidly congeal the tissue.

And, a conveyor for conveying a paper material angle of a predetermined length cut in the cutter, a blower fan remotely disposed from the upper portion of the conveyor for blowing and drying the paper material angle, and paper material transferred and blown to the conveyor A quick cooling tower may be included to rapidly cool the angle.

Hereinafter, the configuration of the present invention will be described in FIG.

At the same time as the paper roll 102 of the paper roll 101 is terminated, the paper feed step S1 for supplying the paper material by changing the direction with the direction change roll and the respective paper materials supplied from the paper feed step S1. Dividing step (S2) for immersing the adhesive of the pool tub 105 by separating the squeezing step, and the lip matching step of laminating the pressure of the plurality of paper materials in which the adhesive penetrated to one side or both sides in the immersion step (S2) (S3), the primary hot air drying step (S4) for hot-air drying the adhesive of the paper material laminated in the late displacement matching step (S3), and the paper 102c passed through the hot air drying step (S4) to pressurize A crimping step (S5) to allow a plurality of paper materials to be mutually compressed, a first bending step (S6) for the primary bending of the laminated paper 102c pressed through the pressing step (S5) at an obtuse angle, and the first bending The obtuse angle formed in step (S6) is bent at a right angle. Orthogonal bending step (S7), the pressing step (S8) for pressing both sides of the paper angle angle bent at right angles by the right angle bending step (S7), and the paper angle angle pressed in the pressing step (S8) Heating for drying the heat through the heating plate 210 when the paper ash angle passing through the secondary hot air drying step (S9) and the secondary hot air drying step (S9) is guided to the guide roller. Detects the paper angle passing through the shaping step (S11), the shaping step (S11) and the shaping step (S11) at right angles to form the paper angle through the heating drying step (S10) at a right angle. Paper which has passed through the cutting step (S12) for cutting by cutting, the rapid cooling step (S13) for rapidly cooling the paper material angle cut in a predetermined length in the cutting step (S12), and the rapid cooling step (S13). Finishing shaping process (S14) for finishing the angle at a complete angle.

Each process described above is described with reference to the flowchart of FIG.

First, in the sheet feeding step S1, the sheet 102 of the sheet roll 101 is terminated, and at the same time, the paper sheet is switched by changing the direction of the sheet of paper supplied to the turning roll 103 for easy operation in the next step. Supply to the process.

In the immersion step (S2), each paper material supplied from the sheet feeding step (S1) is separated to immerse the adhesive of the pull tub 105, and the bottom surface of the upper surface paper 102a adhered to the uppermost side. The adhesive is applied and the adhesive is applied to the upper surface of the bottom surface paper 102b to be bonded to the lowermost side.

In the limb matching step S3, since the limbs of the paper material are slightly shifted from each other, both limbs are arranged so that the paper 102c can be laminated. At this time, the adhesive applied and penetrated into the paper material is guided by the guide roller 104, and at the same time, the adhesive is partially removed so that only an appropriate amount of adhesive remains.

In the primary hot air drying step (S4), the adhesive material is increased by hot air drying the adhesive of the paper material (102c) in the latent matching step (S3), thereby increasing the adhesive force, while the paper material laminated in the paper pressing step (S5) described later is pressed. It allows a plurality of paper materials to be strongly bonded to each other.

In addition, in the paper pressing step (S5), as described above, the paper passed through the primary hot air drying step (S4) is pressurized with a pressure roller to be pressed up and down to increase complete adhesion and rigidity.

And, in the first bending process (S6) to first bend the paper (102c) made from the displacement matching process (S3) at an obtuse angle, this step is a plurality of sheets of compressed paper (102c) at a right angle at a time bending It is preferable to bend in advance at an obtuse angle because wrinkles are generated or abnormal stresses occur inside the overlapped laminated paper.

Further, in the rectangular bending step (S7), a circular shape of the initial angle is formed by bending the obtuse angle formed in the initial bending step (S6) at right angles, and in the pressing step (S8), the rectangular bending step is performed by the rectangular bending step (S7). By pressing both sides of the paper angle, the paper eliminates abnormal stress that may occur during right angle bending and both sides can be compressed to uniform density.

In the secondary hot air drying step S9 and the heating drying step S10, the top and bottom surfaces of the paper angles passed through the pressing step S8 are heated by a heater to dry the undried adhesive.

In addition, in the shaping step (S11), the heat-drying of the previous step (S9, S10) by shaping the paper material angle of the adhesive dried once again at right angles via the secondary hot air drying step (S9) and the heating drying step (S10). When the adhesive is dried, the density change between the adhesive and the paper material is uniformed again to prevent warpage or deformation, and the paper material angle is transferred to the cutting step S12. In the cutting step S12, the predetermined length is changed. Sensing and cutting the paper angle with the cutting blade.

If the paper material angle cut to a predetermined length in the cutting process (S12) as described above is left as it is or stored at room temperature, since the tissue of the adhesive based on sodium silicate is not completely condensed, the adhesive force is easily released and thus the adhesive force is alleviated. The paper ash angle is cut and transferred to the rapid cooling process (S13).

Therefore, in the rapid cooling step (S13), the adhesive is rapidly cooled to allow the tissue to harden in a condensed state in a short time. That is, the adhesive once the tissue is condensed does not change the tissue or weaken the adhesion even at room temperature.

Therefore, even if the paper angle is produced at a high speed by using an adhesive based on sodium silicate, the cross section of the paper angle can be preserved and used as it is.

Even after the adhesive is completely dry and condensed as described above, the paper angle and the chanel are completed by performing a finishing forming process (S14) to pass the finishing forming machine 301 to finish the paper angle at a perfect angle.

On the other hand, in the conventional paper angle manufacturing apparatus,

Conveyor 203 for conveying the paper material angle 110 of a predetermined length cut by the cutting machine 202, and is disposed remotely from the top of the conveyor 203 for blowing air to dry the paper material angle 110 A fan 204 and a rapid cooling tower 205 for rapidly cooling the paper material angle 110 is blown and dried on the conveyor 203.

Therefore, the paper material angle 110 cut from the cutter 202 to a predetermined length is transferred to the rapid cooling tower 205 by the conveyor 203. In this case, the paper angle 110 cut from the cutter 202 is transferred from the upper portion of the conveyor 203. The heat of the paper material angle S10 heated in the secondary hot air drying step S9 and the heating drying step S10 by the blowing fan 204 disposed to have a separation space is first reduced in temperature, and the rapid cooling tower 205 When the paper angle 110 enters, the adhesive of the paper angle 110 is rapidly cooled by a rapid cooling device (not shown).

As described above, when the adhesive is rapidly cooled, the tissue of the adhesive is rapidly condensed as described above. Thus, even if the paper angle 110 is preserved at room temperature, the paper angle 110 having a right angle in cross section is formed. The circle will not be deformed.

In addition, the product is completed by passing through the finishing machine 301 as shown in Figure 2 in order to finish the paper angle of the angle 110 via the rapid cooling tower 205 at right angles.

As described above, the present invention has a very low price, but has a very low condensation rate at room temperature, so that paper angles cannot be produced at high speed. Thus, in order to overcome the drawback of not producing a mass production, an adhesive based on sodium silicate is used. By rapidly cooling the paper angle passed through the cutting process in the rapid cooling process, the tissue can be quickly condensed, thereby reducing the production cost by using adhesives based on low-cost sodium silicate. It is possible to achieve the same mass production as using expensive adhesives, so that the competitiveness can be strengthened, and in the case of using the expensive adhesives (adhesives with high setting speeds) conventionally used in the above manufacturing process, they are faster than the existing production speed. It has the effect of minimizing the defective rate The invention is very excellent.
