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 includes a folded advertisement billboard for unused paper or newspaper, an old newspaper and a used newspaper. Use a single or multiple sheets of processed paper material, such as used paper, such as printed paper and used corrugated cardboard, made of copy paper, OA equipment, etc., and cut them into intermittent strips in multiple rows of narrow widths. A fine wrinkle is formed in the intermittent part where the notch does not enter, and after making a cut, the processed paper material is semi-forced through a narrow passage to form a wavy wrinkle throughout the narrow band body, and one unit of the narrow band body is formed. It also forms fine wrinkles so that it can be used immediately as a conveyed product or various cushions without any modification. And an object that it has to be excluded by. 2. Description of the Related Art For example, cushions to be packed between a boxed conveyed object and a box so as not to damage the boxed conveyed object are made of paper instead of synthetic resin due to pollution problems. Things are known. The simplest one is one in which newspaper is rolled, or a paper material is cut into shreds and then rounded to form a paper mass, or, depending on the application, 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 a strong kraft paper, and the paper material is spread to form a small honeycomb-shaped mesh. [0003] However, among the above-mentioned paper cushions, the former, which is made by rolling newsprint, is troublesome in work and has a variation in quality.
Also, the shredded paper chunks may be soft, but since each one is independent, it is easy to scatter and the workability is poor, 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. Further, 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-like mesh is formed by the notch and the connecting portion when the sheet is expanded, and when this is rounded, a somewhat fluffy feel can be obtained. There is a limitation on the processing size of the above, and it is not possible to process a plurality of sheets at the same time. And since the processed mesh is small, the elongation rate when pulling it in the horizontal direction is small, and when it is rolled, the ratio of containing air is small, and the connecting part is short, so it must be stretched horizontally unless it is made of strong paper material The joint is easy to cut when It is a thin paper material because it is a finer mesh,
This can also be formed only for each single sheet. Moreover, a wave is applied at the same time when the cut is made, and no shrinkage chicks are formed. Also, in the case of a large non-standard paper material 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. [0004] Therefore, the present invention is provided to solve the problems of the conventional paper cushion and to achieve the object of the invention. A first aspect of the present invention is a paper cushioning material manufacturing apparatus, in which a pair of horizontally long roller bodies are formed with a concave and convex groove having a constant width, and a peripheral edge of a circumferential surface of the convex groove is used as a cutting blade, A notch recess into which the paper material to be processed enters over the entire width of the convex groove is formed in a part of the opposed circumferential surface of each convex groove, and the concave and convex grooves of both roller bodies are engaged with each other, and A concave and convex piece of the scrap removing body is fitted to the concave and convex groove on the discharge side of the body, and a scrap removing body having upper and lower convex pieces for scraping out the processed paper material in the concave groove and forming a wrinkle.

The wave a of the entire narrow band and its one unit of narrow band 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. body frizz forming wrinkles b fine, the upper suppression member 16 ₁ against the weight body 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 P formed by the roller bodies 1 and 2 is such that the cut 7 along the concave and convex grooved blade 1 'and the connecting portion (7 ₁ , 7 ₂ ... 7 n) are alternately formed in the paper material. are formed on, 7 and two connecting portions two rows of cuts _{(7 1 · 7 1, 7} 2 · 7 2 ...... 7n · 7n) is formed for fine strip member 11, 12, 13 of three rows . Next, when the wire is pulled in a direction perpendicular to the length direction of the cut, a mesh 7 'having a size as shown in FIG. 6 is formed. The processed paper material that has entered the cutout recesses 6 in the width direction of the narrow band body forming the mesh forms creases c formed by the cutout recesses and a wave forming guide 16.
The wave a and the wrinkle b are formed on the wave. When the width of the paper material P 'is larger than the standard, the paper material P' is inserted into the roller bodies 1 and 2, and the paper material is simultaneously processed at the outer position while being processed by the concave and convex grooves 3 and 4. Excess portions that protrude in the lateral direction due to the engagement of the ridges 4 of the roller body 4 are cut. At this time, the reinforcing member 25 is provided on the processed paper material discharge side of the casing 20, but before reaching the reinforcing member 25, the protruding groove 23.
Since the surplus portion is cut by 24, the processed paper P and the surplus portion do not hit the reinforcing member 25, and there is no problem in discharging the processed paper material. Since the present invention has the above-described configuration, it does not fall apart when cutting various kinds of paper materials, there is no fear of scattering the surroundings, and the cushion and packing are required. Since paper cushioning does not use any chemicals, there is no need to worry about pollution. In addition, since cutting can be performed by a pair of horizontally long roller bodies so as not to be separated, a normal processed paper material, for example, a folded paper billboard of unused paper material or newspaper, an old newspaper, a used copy paper, and an OA device. Using printed paper, used cardboard, etc. on a single sheet or on multiple sheets, making cuts in multiple rows of narrow widths in an intermittent band shape, and further forming a wave on the cut cut processed paper material as it is And can be used immediately as an action. When the paper is cut by the roller and discharged, the strip of paper in which the processed paper material fits into the concave groove of each roller is almost wrapped around the roller if there is no debris formed by a convex piece. However, it is possible to form fine wrinkles while peeling off with the scrap removing body. Therefore, a relatively large wave and a thin band such as the wave are mixed with fine wrinkles without any modification, so that a softer cushion containing a large amount of air can be obtained. Further, a wave is formed through the notched processed paper material through the wave forming guide over the entire narrow band,
By forming fine wrinkles perpendicular to the length direction also on the unit strip, a considerable height is also formed in the paper thickness direction of the processed paper material, so this is not expanded An effective cushion can be obtained without any change in the state as it is. Further, according to the present invention, even if the paper material to be processed is wider 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, the excess portion that protrudes in the lateral direction due to the engagement of the convex grooves of the roller body located at the outer position is cut, so that the irregular size is irregular and irregular. It can also be processed with paper.
