Description

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

  When an article moves in the container when the article is accommodated in a container such as a cardboard box, the article is damaged or damaged. Therefore, a cushioning material is used to fill a space between the article and the container and absorb an impact applied to the article. One such cushioning material is a paper cushioning material in which a slightly thick soft paper such as kraft paper is creased to give cushioning properties.

  Such a cushioning material is manufactured by pulling out paper from a roll around which the paper to be used as a raw material is wound, making the shape close to a rod shape by attaching a flange, and then cutting it into an appropriate length. Patent Document 1 describes an apparatus that performs this electrically. The paper wound in a roll shape is drawn out by a roller driven by a motor, and both ends provided between the raw paper roll and the drawing roller. The wrinkles are made by passing through a forming bar and a narrow opening for curving.

  Patent Document 2 describes a manual type. The shock absorber manufacturing apparatus includes a holding unit that holds a roll around which a paper material is wound, a pair of side plates that become narrower as the distance from the holding unit, and a connection plate that has an opening provided at the ends of both side plates. A frame made of is housed in a box container. A wave shape for gathering is formed at the periphery of the opening. After the paper material is pulled out from the roll and narrowed by a pair of side plates, the paper cushioning material is pulled out through the opening of the frame and box container. Is produced.

  Since the electric type as described in Patent Document 1 requires a motor, it is difficult to reduce the size and weight, and when it is used continuously for a long time, a power source is required, so the place of use is limited. Therefore, the manual type is excellent for easily producing a paper cushioning material, but the cushioning material manufacturing apparatus of Patent Document 2 is composed of a double structure of a frame and a box container, and is complicated so that it can be assembled. take time. Also, when replacing the roll, it is necessary to take out the frame from the box container, which is troublesome. In addition, when paper material remains on the roll, even if it is attempted to take out the frame from the box container, it is difficult for the paper material to be caught by the opening of the frame and the box container.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a paper cushioning material manufacturing apparatus having a structure in which an assembling operation is easy and a roll around which a paper material is wound can be easily replaced. That is.

The present invention made to solve the above problems is a paper cushioning material manufacturing apparatus for manufacturing a paper cushioning material from a roll wound with a long raw paper material,
a) a main body composed of two opposing substantially trapezoidal front and back plates, and two side plates connecting the oblique sides of the front and back plates;
b) A roll holding portion provided on the long bottom side of the trapezoid of the main body portion and rotatably holding both ends of the shaft of the roll disposed in parallel with the long bottom.

  The method of using the paper cushioning 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 of the paper by hand, and pulls it out from the opening of the main body formed on the short bottom side of the trapezoid of the main body. Then, both ends of the shaft of the roll are held by the roll holding unit. At this time, the long paper material is slightly wrinkled in the longitudinal direction within the main body, but there is no problem. Thereafter, when the paper material pulled out from the opening is further pulled out, the longitudinal wrinkles in the main body portion are extended, and then the paper material is unwound from the roll and is brought closer by the both side plates of the main body portion. The paper material that has stopped is pulled out from the opening. The paper material can be used as a cushioning material by tearing the paper material by hand or cutting with scissors or the like at an appropriate length. If the raw paper is perforated, cut it at that point.

  The main body is preferably made by bending a sheet of cardboard, cardboard, plastic or the like. Thereby, manufacture becomes easy and it can reduce in weight. Among these, corrugated cardboard or cardboard is desirable in that it does not give a load to the environment at the time of disposal.

  In that case, it is preferable that the roll holding portion is formed by bending a sheet material inward from a side sandwiched between the two long bottoms of the side plate. Thereby, a roll holding | maintenance part can also be integrally formed with the same sheet material as a main-body part, and it contributes to weight reduction.

  Moreover, it is desirable to provide a lid on the roll holding part side of the main body part. As in the above case, the lid is preferably formed by extending a sheet material from the long bottom.

  The paper cushioning material manufacturing apparatus according to the present invention includes a front plate and a back plate whose main body portions are two opposing substantially trapezoidal trapezoidal plates, and two oblique sides of the front plate and the back plate that are connected to each other. Since the roll holding portion is provided on the long bottom side of the trapezoidal shape, it is small and lightweight, and the assembly work is easy. Moreover, since a power source is unnecessary, the place of use is not limited, and it can be taken and used in any site where a paper cushioning material is required.

  In the paper cushioning material manufacturing apparatus according to the present invention, it is possible to easily set a long raw material paper roll, which is a raw material of the paper cushioning material, to the roll holding unit. Can easily remove the raw paper roll from the roll holder and attach another raw paper roll to the roll holder. For this reason, the required type of paper cushioning material can be manufactured by switching in a short time.

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