Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a paper cushioning material, and is used to insert unused advertising materials such as paper or newspapers, old newspapers and used newspapers. Use a single or multiple sheets of processed paper material consisting of old paper such as printed paper, used cardboard, etc., made of copy paper, OA equipment, etc., and cut them into multiple rows of narrow and intermittent bands, and cut them. After putting the processed paper material through the narrow passage semi-forcefully, the entire narrow band is formed into a corrugated shape, and each unit of the narrow band is also finely crimped to form a conveyed object and various cushions It is an object of the present invention to make it possible to use a large-sized non-standard paper to be processed at a predetermined width and at the same time to cut off an excessive portion, while allowing the paper to be used to be processed without any modification. 2. Description of the Related Art For example, in order to prevent damage to a packaged conveyed article and a box between the conveyed article and the box, the cushion is made of paper instead of synthetic resin due to pollution problems. Things are known. The simplest one is one in which newsprint is rolled, or a paper material is cut into shreds and then rolled to form a paper mass, or, depending on the application, a cardboard is cut and interposed. Alternatively, there is known a kraft paper in which short cuts and connecting portions are formed by press working on strong kraft paper, and the paper material is spread to form a small substantially honeycomb-shaped mesh. [0003] However, among the above-mentioned paper cushions, the former, which is made of rolled up newspaper, is cumbersome to work and varies in quality. Also, although the shredded paper mass may be soft, it is easy to disperse and workability is poor because each one is independent, and it is difficult to use it as it is, so it is used in a paper bag or plastic bag, If the bag is torn, a shredded piece of paper will protrude from the torn portion, which is not preferable. The cut cardboard has a constant thickness, but is not very preferable as a cushion because it is hard itself. In the latter, a small honeycomb-shaped mesh is formed when the sheet is expanded by the notch and the connecting portion, and when this is rounded, a somewhat fluffy feel is obtained. There is a limitation on the processing size of a plurality of sheets, and a plurality of sheets cannot be processed at the same time. [0004] Since the processed mesh is small, it has a low elongation when it is pulled in the lateral direction, and when it is rolled, it has a low proportion of air and has a short joint, so that it must be a strong paper material. When stretched to the side, the joint is easy to cut. Further, since it is a fine mesh, it is a thin paper material, and it can be formed only for each single sheet. Also,
In the case of large non-standard paper to be processed, it cannot be applied to the processing roller. For this reason, there is a problem in that a large non-standard paper to be processed must be cut one by one with another cutter so as to meet the standard. [0005] Accordingly, the present invention is to solve the problems of the conventional paper cushion and to provide the object of the invention. That is, the present invention
In the apparatus for manufacturing a cushioning material made of paper, an uneven groove having a constant width is formed on a pair of horizontally long roller bodies, and a peripheral edge of the circumferential surface of the convex is defined as a cutting blade, and one of the opposing circumferential surfaces of each convex groove is formed.

When the processed paper material passes, the passage 5 is compressed and contracted by the narrow passage to advance against the weight body, and the passage gradually expands to form a wave a at the height h of the passage. While discharging.
In this case, the waves alternately undulate in the concave and convex grooves of the roller bodies 1 and 2 (that is, when the paper material of the lower roller body undulates upward, the paper material of the adjacent upper roller body undulates downward), and Fine shrinkage b is also formed in the strip body for each unit. 20 is a casing which covers the roller body 1, 2, axis 1 ₁ of the roller body 1, second outer position in the bearing portion 20 ₁ integral with the casing
- 2 ₁ while bearing, it is formed an opening 21 for the processed sheet material to the casing portion passes. 2
Reference numerals 3 and 24 denote convex grooves which are not provided with the cutouts 6 located outside the convex grooves 3 and 4 of the roller bodies 1 and 2 and are integrally formed at the same diameter as the convex grooves 3 and 4 of the roller body. It has been molded. Reference numeral 25 denotes a reinforcing member provided on the processing paper material discharge side of the opening-side casing, and stabilizes the opening of the opening by providing the opening 21 with a cantilever type. Next, specific steps of the present invention will be described. That is, in the embodiment shown in FIGS. 1 to 4, a pair of horizontally long roller bodies 1 and 2 are provided with concave and convex strips 1 ′ and 2 ′ having a fixed width.
And a notch 6 formed in the same direction on the circumferential surface R, and the concave and convex groove blades of both the roller bodies 1 and 2 are engaged with each other. When the paper material P 'is inserted, a cut 7 along the blades 1' and 2 'of the concave and convex grooves and a connecting portion (7 ₁ 7 ₂ ...) are inserted into the paper material.
... 7n) is 7 and one connecting portion cuts of one column relative to narrow band body 11, 12 of the two rows are alternately formed ₍₇ 1, _{7 2} ......
7n) is formed. Then, the processed paper material that has passed through the roller bodies 1 and 2 will be wound around the circumferential surface of each roller body as it is, and the degree of winding of the paper material in the concave groove is particularly high, by the work sheet material to be Makitsuko convex pieces 17 ₁ of weed body 17 made of uneven pieces discharged in a linear direction, it is inserted into the wave shaping guide 16 which is continuous to the weed body. At this time, when the paper material on the concave groove side of the lower roller body is peeled off by the lower scrap remover 17, the paper material on the concave roller side of the upper roller body moves upward, and the paper material on the concave groove side of the upper roller body is removed from the upper scrap body. When peeled off by the body 17, it proceeds downward. The wave a of the entire narrow band and its one unit of narrowness are reduced within the height h of the guide passage 5 while being compressed toward the front of the guide passage 5 narrowed by the weight body 18 at the distal end portion of the upper suppressing member. A fine crimp b is formed in the band, and the upper suppressing member 1 is opposed to the weight.
6 ₁ is discharged from the outlet of the wave shaped guide 16 while expanding the passage 5 by moving upward through a hinge 19 (FIG. 7). In addition, the cut of the processed paper material formed by the roller bodies 1 and 2 is formed by connecting the cut 7 along the concave and convex groove blade 1 ′ to the paper material (7 ₁ .7 ₂ ...).
.. 7n) are alternately formed, and three rows of narrow strips 11, 12,.
13, two notches 7 and two connecting portions (7 _1.
7 ₁ , 7 ₂ 7 ₂ ... 7n 7n) are formed. Then, pulling in the direction perpendicular to the length direction of the cut,
A mesh 7 'having a size as shown in FIG. 6 is formed. And
If the width of the processed paper material P 'is larger than the standard, it is inserted into the roller bodies 1 and 2, and the processed paper material is processed by the concave and convex grooves 3 and 4, and at the same time, the roller at the outer position is processed. Excess portions that protrude in the lateral direction due to the engagement of the ridges of the body with each other are cut. At this time, the reinforcing member is provided on the processed paper material discharge side of the casing 20.
Before reaching the reinforcing member 25, the surplus portion is cut by the convex grooves 23 and 24 without the notch 6 located outside the roller body, so that the processed paper material P and the surplus portion may hit the reinforcing member 25. There is no problem in discharging the processed paper material. Since the present invention has the above-mentioned structure, it does not fall apart when cutting various kinds of paper materials, there is no fear of scattering the surroundings, and it is necessary for the cushion packing. Since no paper cushioning material is used, there is no need to worry about pollution. In addition, since a pair of horizontally long roller bodies can be cut so as not to fall apart. ・ By a normal processed paper material, for example, an unused paper material or a folded advertisement billboard such as a newspaper, an old newspaper, a used copy paper, and an OA device. Using a single piece of printed paper, used cardboard, etc., or a stack of multiple pieces, making cuts in multiple rows of narrow widths in an intermittent band shape, and further forming a wave on the cut-out processed paper material as it is You can use it as an action immediately. When the paper is cut by the roller body and then discharged, the processed paper material tends to wind around the roller surface. Particularly, the narrow band located in the concave groove is almost wound around the roller body without the scraping body. Can be peeled off by the scrap removing body. When the cut-out paper material is expanded, a large mesh is formed as shown in FIG. 6. When the paper material is rolled from this state, a softer cushion containing a large amount of air can be obtained. Furthermore, since the notched cut processed paper material is formed into a wave and a fine shrinkage of each unit is formed, a considerable height is also formed in the bite thickness direction of the processed paper material. An effective cushion can be obtained without expanding and without any modification. Furthermore, according to the present invention, even if the paper material to be processed has a width larger than the standard, when this is inserted into the roller body,
While processing the paper material to be processed with the concave and convex grooves, at the same time, it is cut into an excess portion that protrudes in the lateral direction due to meshing between the convex grooves of the roller body located at the outer position, so that paper of irregular size and irregular size Materials can also be processed.
