2. Description of the Related Art FIGS. 3A and 3B are structural explanatory views of a conventional example of a cushioning material molding machine, and FIG. 4 is an explanatory view of an example of the shape of a cushioning material that has been conventionally used. There are various types of cushioning materials used as filling materials for crevices when delivering vegetables, fruits, electrical parts, mechanical parts, ceramics, etc. For example, a styrene foam, urethane, vinyl chloride or the like is compressed between an upper mold and a lower mold by a compression molding machine 12 as shown in FIG. Alternatively, the finely cut paper 14 by the shredder 13 shown in FIG. 3 (b) is used as it is, or it is packed in a bag made of polyethylene or the like.

However, the above-mentioned styrofoam used as a raw material has a high production cost, and there are problems that the incinerator is burned out at the time of final incineration and the like, and a harmful gas that causes pollution is generated. In order to solve the problem, a cushioning material using a large amount of waste paper generated in office buildings etc. as an alternative raw material has come to be created, but the same molding method and the same molding method as when using a chemical product such as Styrofoam as a raw material The current situation is that the usage is adopted.

[0004]

However, the cushioning material made of recycled recycled paper has the drawback of not being versatile and poor in elasticity when compression-molded, and when using cut paper pieces as they are. There is a problem in that it easily scatters during packing / unpacking, and when the paper pieces are packed into bags, the bag cost and labor and time are required. In order to deal with these problems, the waste paper is cut into a predetermined size and then formed into a rope.
A molding machine has been proposed in which used papers are appropriately matched, such as by knitting in a string shape or a net shape, as a cushioning material.

The object of the present invention is to solve the above-mentioned problems, and in the process of using waste paper as a material, cutting it, and molding it, appropriately select the finished shape and strength, diameter, length, etc. By doing so, it is possible to provide a molding machine that can supply a large amount of a highly versatile cushioning material that can meet the specifications of a wide variety of products to be packed at low cost.

After cutting and completion of molding, the completed cushioning material 11 is discharged to the product container 8. The container is filled with the completed cushioning material 11 and the molding machine is stopped.

In this molding machine, by selecting the model of the braid knitting machine 5, it is possible to form a cushioning material having various shapes such as a rope-like shape, a string-like shape, and a net-like shape. In addition, the diameter of the string can be arbitrarily set by increasing or decreasing the amount of cut paper pieces to be twisted together, and the hardness, stiffness, etc. can be arbitrarily set by changing the cutting length or the degree of strength. It is possible to continuously form a large amount of cushioning material having properties corresponding to the specifications of products to be packed and delivered.

Even if the raw material is waste paper that requires confidentiality, it is cut into a fine width, so there is no risk of leaking secrets, and after being used as a cushioning material for packaging, it is recycled to recycled paper or trays. It is also possible. In addition, since only used papers are used as raw materials and no chemical products are used, there is a feature that secondary pollution does not occur even when finally incinerated.
