Description

  The present invention relates to an apparatus for producing a paper cushioning material that is used by being packed in the space between a container and an article, for example, when transporting the article.

  When an article is accommodated and transported in a container such as a cardboard box, movement of the article in the container may damage or break the article. Therefore, cushioning materials are used to fill the space between the article and the container and to absorb the impact applied to the article. One of such cushioning materials is a paper cushioning material having a cushioning property, such as kraft paper or the like, which is made of a slightly thick soft paper with a crease.

  Such a shock absorbing material is produced by pulling out the paper from a roll on which the material paper is wound, putting a crease by pulling the paper to make it into a rod-like shape, and then cutting it into an appropriate length. Patent Document 1 describes a device that electrically performs this, in which a roll of paper is drawn by a motor driven roller and both ends are provided between the raw paper roll and the draw-out roller. The bar is crimped by passing it through a forming bar and a narrow opening for curving.

  Patent Document 2 describes a manual type. This shock absorbing material manufacturing apparatus includes a holding portion for holding a roll on which a paper material is wound, a pair of side plates whose width is narrowed with distance from the holding portion, and a connecting plate provided with an opening at the tip of both side plates. The frame which consists of is accommodated in a box container. A corrugated shape is formed on the periphery of the opening, and the paper material is pulled out of the roll, narrowed in width by a pair of side plates, and then pulled out through the opening of the frame and box container to make a paper shock absorbing material Is made.

  The motorized type as described in Patent Document 1 requires a motor, so that reduction in size and weight is difficult, and when it is used continuously for a long time, a power source is required and the use place is limited. Therefore, although the manual type is excellent for easily producing a paper shock absorbing material, the shock absorbing material manufacturing apparatus of Patent Document 2 is composed of a double structure of a frame and a box container, and is complicated because it is complicated. take time. Moreover, when replacing the roll, it is necessary to take out the frame from the box container, which takes time and effort. In addition, when the paper material remains on the roll, even if it is attempted to take out the frame from the box container, the paper material is caught by the opening of the frame and the box container and is difficult to take out.

  The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a paper shock absorbing material manufacturing apparatus having a structure that is easy to assemble and that it is easy to replace rolls wound with paper material. It is.

The present invention made to solve the above-mentioned problems is a paper shock absorber manufacturing apparatus for manufacturing a paper shock absorber from a roll on which a long raw paper material is wound,
a) A main body portion comprising a front plate and a back plate which are two opposing substantially identical trapezoidal plates, and two side plates connecting both oblique sides of the front plate and the back plate;
b) It has a roll holding portion provided on the long bottom side of the trapezoidal shape of the main body portion, which holds both ends of the axis of the roll disposed parallel to the long bottom rotatably.

  The usage method of the paper shock absorbing material manufacturing apparatus according to the present invention is as follows. First, the user pulls out the raw paper material from the roll, squeezes the tip by hand, and pulls it out of the opening of the main body portion formed on the short bottom side of the trapezoid of the main body portion. Then, both ends of the roll shaft are held by the roll holding unit. At this time, although the long paper material has some wrinkles in the longitudinal direction in the main body, there is no problem. Thereafter, when the paper material being drawn out from the opening is further drawn out, the longitudinal crease in the main body portion is extended, and thereafter, the paper material is unrolled from the roll, and is spread by the side plates of the main body portion. The loose paper is pulled out of the opening. The paper material can be used as a shock absorbing material by manually tearing it with an appropriate length or cutting it with scissors or the like. If the raw paper material has perforations, cut it at that point.

  It is desirable that the main body portion be manufactured by bending a sheet material such as a cardboard, a thick paper, a plastic or the like. This facilitates manufacture and can reduce the weight. Among these, corrugated cardboard or cardboard is desirable in that it does not burden the environment upon disposal.

  In that case, it is preferable that the roll holding portion be formed by bending a sheet material inward from a side sandwiched by the two long bottoms of the side plate. Thus, the roll holding portion can be integrally formed of the same sheet material as the main body portion, which contributes to weight reduction.

  Preferably, a lid is provided on the roll holding portion side of the main body portion. It is desirable that the lid be formed by extending the sheet material from the long bottom as described above.

  The paper shock absorbing material manufacturing apparatus according to the present invention comprises a front plate and a back plate, which are two substantially opposite trapezoidal shaped plates, and two sheets connecting the two oblique sides of the front plate and the back plate. It has a simple configuration in which the roll holding portion is provided on the long bottom side of the trapezoidal shape, and therefore, it is compact and lightweight, and the assembly operation is easy. In addition, since the power source is unnecessary, the place of use is not limited, and it can be taken and used at any site where a paper shock absorbing material is required.

  And in the paper shock absorbing material manufacturing apparatus according to the present invention, a long raw paper material roll, which is a raw material of the paper shock absorbing material, can be easily set in the roll holding portion. Even if it remains, it is possible to easily remove the raw material paper material roll from the roll holding portion and attach another raw material paper material roll to the roll holding portion. For this reason, the paper-made shock absorbing material of the required kind can be switched and manufactured in a short time.

  The paper shock absorber manufacturing apparatus according to the present invention may be provided (sold) in a form in which a roll on which a raw paper material is wound is set in advance in the roll holding unit.
