TECHNICAL FIELD The present invention relates to a hollow hollow cushioning material made of Fuji, which is smooth without any step and excellent in strength, and an apparatus capable of continuously manufacturing the buffering material.

Styrofoam is widely known as a cushioning material used for the safety of packaged products. However, as environmental issues have emerged as social issues, they have been developed into legally regulated subjects. As a result, they have to replace styrofoam buffers.

One such alternative is paper buffer. In the case of the paper buffer material, a cardboard is given priority. Corrugated cushioning material is made by stacking several sheets of corrugated paper cut to design dimensions and bending them into an angle shape, and finishing by post-processing by uneven processing or grooves to suit the product. You can't help but lift it.

What is proposed in order to supplement the buffer material laminated | stacked the some corrugated board is the buffer material which laminated | stacked and laminated several layers of Fuji. The buffer material made of Fuji is a spiral wound of paper tape, which tends to luster due to low bending stress of the bent portion (inverted portion). In the hollow cushioning material made in Fuji, such luster is particularly unstable because the greater the weight of the product, the greater the likelihood that the product will stumble during handling, such as transportation, loading and unloading, and transportation. In addition, the compressive strength is low. Because of this weakness, the cushioning material of corrugated cardboard is low in product value as the weight of the product is insufficient.

A further development of corrugated buffer was the Fuji buffer. Fuji buffer is a hollow cushioning material that is formed by bending a jointed pipe while spirally wrapping a long strip of paper. The buffering role is insufficient due to its low strength of lamination and the luster of the bent portion. In addition, the consumption of the material is excessively economical compared to the buffering role, and the paper tube tends to be partially damaged in the process of forming the spiral paper tube into a predetermined shape later, which makes it difficult to maintain quality and high manufacturing costs (see Patent No. 373490). .

Because branch tubes are limited in length, they cannot produce longer branch tubes as well as buffer buffers.

In addition, the spiral-wound paper-based buffering material is seemingly unsightly due to the layers of the paper strips pitched diagonally, and tends to stumble when the cushioning material is manufactured from the material by the step thickness of the material Fuji.

On the other hand, the conventional cushioning material 1, whether corrugated or Fuji, is joined to overlap the ends as shown in Fig. 1, so the joint step 2 is inevitable. When the junction step 2 reaches the bottom of the packing box, the entire package, including the product, is not only shaken, but also the packing space is increased, the design dimension of the box is increased, and the cost burden is increased.

In addition, the conventional Fuji control buffer material is made of a paper tube with a constant length first, then molded and cut to the required length, or the ready-made product completed through the pre-cut post-molding process is purchased by the buffer material manufacturer and cut and processed to the size desired by another consumer. There is a lot of stub occurrence. From the standpoint of the manufacturer of the cushioning material, it is clear that the economic loss will be as large as the scrap. In order to overcome the shortcomings of the corrugated cardboard and Fuji buffer buffers, it is important to strengthen the cushioning role to protect the product by increasing the strength and resilience, and to eliminate the bonding step.

At the same time, the hollow cushioning material made of Fuji, which can exert excellent product protection function with high restoring force (elasticity) by continuously molding the cushioning material in the shape reflected in the design at the same time as the steel making, is produced continuously by the long material longer than the conventional paper pipe. It is also necessary to provide an apparatus for manufacturing to increase the processing economics by reducing the waste generated when processing the cushioning material by providing to the.

Accordingly, an object of the present invention is to overcome the disadvantages of the corrugated cardboard and Fuji buffer, and to provide a smooth hollow hollow cushioning material having excellent cushioning function due to high laminated bonding strength and bending stress and no joint step.

Another object of the present invention to provide a Fuji hollow hollow cushioning material manufacturing apparatus that can efficiently manufacture the above-described hollow hollow cushioning material without being limited in length.

The first task is to laminate a plurality of Fujis having a constant width with a constant margin in the width direction to form a laminate having female and male joints formed on both sides in the width direction, and the female and water joint ends of the joints each other. The hollow cushioning material having an arbitrary cross-sectional shape can be achieved by bending in the width direction so that there is no manna step.

The second object of the present invention is a paper feed section for loading and supplying a plurality of roll-shaped Fujis at equidistant distances so as to be released with a certain margin at both ends in the width direction, and on one side of the roll-shaped Fuji released in a direction where the subsequent process proceeds. The adhesive coating unit for applying the adhesive, the bonding portion for pressing and bonding the adhesives coated with high strength, and the jointing portion for deforming the paper into tubular through a sequential bending process, press the female and water joint end of the paper The shock absorber molded parts that are molded to have an arbitrary cross-sectional shape while joining are arranged in a line along the direction of the process, so that the hollow buffer material can be continuously manufactured with high strength, excellent restoring force, and no joint step in the joint. It can be achieved by a Fuji hollow cushioning material manufacturing apparatus.

With reference to the accompanying drawings of Fig. 2 made based on a preferred embodiment of the present invention will be described in more detail.

Figure 2 illustrates a cross section of the paper 10, which is the base of the hollow hollow cushioning material made of Fuji.

The paper 10 is laminated with a long width (roll-shaped Fuji) of constant width so that a constant margin in the width direction is laminated and pressed to join so that a stepped female joint 11 and a male joint 12 are formed on the side. It is. The paper 10 is based on the premise that the number of laminations is adjusted accordingly according to the design of the hollow cushioning material having this fabric.

After bending the paper 10 in the width direction and joining the female and male joint ends (11, 12) to match, or while the bonding apparatus having a core having an arbitrary shape and pressing means corresponding to the core is provided It is molded to obtain a hollow cushioning material 20 made in Fuji as shown in FIG.

When laminating a plurality of Fujis and joining the female and male joint ends 11 and 12, an adhesive is applied over the entire one side of each Fuji, and then hardened by pressing the core and pressing means before hardening. When laminating and joining, if the adhesive applied over the whole of one side of each Fuji is hard to start the adhesive force, the adhesive may be applied to the female and male joint ends 11 and 12 separately and joined in the above-described manner.

The Fuji hollow cushioning material 20 is not easily deformed due to its strength is very high compared to the conventional Fuji hollow hollow cushioning material, which is joined by using only a spiral winding force, that is, a winding force, to be joined to form multiple layers. The road goes long. Also, as illustrated in FIG. 3, the buffer member having the bent portion 21 also has the same strength as that of the bent portion 21 and has excellent restoring force. Thus, the buffering role is also superior to that of the spiral winding type buffer member.

In addition, the parts where the female and male joints 11 and 12 meet and join are joined together with the female and male joints 11 and 12 given by Fuji, facing each other, as if the bricks are alternately stacked. As the bonding strength is maintained, the bonding step is maintained while the bonding step disappears, and the space occupied in the packing box is reduced, thereby reducing the packaging volume.

The following is a description of an apparatus capable of efficiently manufacturing the above-described hollow hollow cushioning material. In the following description, reference numerals not shown in FIGS. 4 and 5 refer to those of FIGS. 2 and 3.

In FIG. 4, the Fuji-type hollow cushioning material manufacturing apparatus 30 of the present invention includes a paper feeding part 31, an adhesive applying part 32, a lamination part 33, a pipe forming part 34, and a cushioning material molding part 35. It is composed.

The paper feeding unit 31 unwinds the plurality of roll-shaped Fujis 31a to 31n so that a certain margin remains in the width direction thereof, and then stacks the stepped arms and water joints on both sides of the width direction so as to form the stepped Fuji. It is arranged to be fed at an equidistant distance.

The adhesive application part 32 applies an adhesive (housing) over one side (the bottom face of Fuji in the drawing) when each roll-shaped fuji 31a to 31n of the paper feeding part 31 is released. It is a normal adhesive agent application part made up, and it is more efficient to arrange the number of Fuji 31a-31n and the same number at equal intervals up and down, and to make application | coating work efficiency and apparatus simple.

The lamination part 33 presses the FUJI 31a-31n to which an adhesive agent is apply | coated at once, and joins and laminates high strength, leaving both female and water joint ends 11 and 12 on both sides, and presses the upper and lower press rolls 33a and b. It is composed of

The conduit guide portion 34 is to bend only to the extent that the female, male joint end (11, 12) is not bonded to the bonding paper 10 to be joined to the buffer material forming part 35, a universal metal pipe manufacturing apparatus It is the same as the structure of the canning section of the pipe.

The shock absorbing material forming part 35 is formed by the shock absorbing material 20 having a desired hollow cross section while forcibly joining the female and water welding ends 11 and 12, and immediately before the female and water welding ends 11 and 12 meet. The core 35a made in the hollow cross-sectional shape of the cushioning material 20 to be obtained at the position is placed to support the inside, and the outer surface is pressed by a pressure roll 35b having a shape corresponding to the core 35a. The shock absorbing material is completed by joining the ends 11 and 12 with high strength.

In the sheet feeding section 31, a plurality of rolled-type Fujis 31a to 31n are attached to the adhesive applying portion 32, the laminating portion 33, the pipe forming guide portion 34, and the cushioning material forming portion 35, leaving a constant margin at both ends in the width direction. Loosen and load the fuel cell by way of) and operate the apparatus so that the traction force is exerted on the cushioning material at the end side (a).

The adhesives 31a to 31n, which are released from the paper feeding part 31 with a certain margin in the width direction, are uniformly coated on one side while passing through the adhesive applying part 32. After the adhesive is applied, it is pressed by force while passing through the lamination section 33 to be laminated. At this time, the marginal portions of the respective Fujis 31a to 31n are not laminated and remain as stepped arms and water joints 11 and 12. The paper is then bent to the extent that the female and male joint ends 11 and 12 do not stick to each other while passing through the canal guide portion 34 and are deformed into an unfinished canned tube.

Referring to FIG. 6, the unfinished steel pipe is supported by the core 35a while being folded into the shock-absorbing material forming part 35, and is crushed by the pressure roll 35b while being folded by the female and water-bonded end ( 11 and 12 are press-bonded in the form of overlapping two stairways to form a buffer material 20 having a hollow as the cross section of the core 35a, and bent at a right angle using the auxiliary pressing roll 35c. It is molded into a cushioning material of the same aspect. The manufacture of this series of Fuji hollow cushioning materials is continued without interruption until the rolled-type Fujis 31a to 31n loaded in the paper feeding section 31 are exhausted.

In order to change the cross-sectional shape of the hollow hollow cushioning material having no joint step as described above, the core 35a of the cushioning material forming part 35 is replaced with a core having a desired cross section, and the pressure roll 35b is also mounted on the core 35a. Replace it with a compatible one.

Of the pressure rolls bound to the lamination part 33, the tube forming part 34, and the buffer material forming part 35, the upper or lower pressure roll is the driving side, and the pressure roll corresponding thereto is at the terminal end (a). A series of manufacturing processes can be carried out smoothly from supply of Fuji to molding out of the cushioning material without installing a separate traction device.

As described above, the Fuji hollow cushioning material according to the present invention is smooth because there is no joining step, and thus the quality is outstanding, and the strength is higher than that of the spiral winding-bonded Fuji hollow buffer material, and thus the life of the laminated state is long. In addition, even in the case of the buffer member having the bent portion, since the strength is large, the restoring force is excellent, so the buffering role does not change.

And the said manufacturing apparatus can manufacture the said hollow hollow buffer material efficiently.
