Abstract

(57) [Abstract] [Purpose] To produce a cushioning frame for packaging, which is mainly used for transporting equipment such as color printers, by using pulp fiber waste material, to improve productivity and to reduce cost. is there. [Composition] Molded and manufactured from waste pulp fiber material, and the molded product is formed with a concave-convex shell that conforms to the concave-convex shape of the adherend equipment. A cushioning frame for packaging that is configured to have a convex shape and a concave shape that fit with each other when shrinking to reduce the overall surface in a plane.

Description

[Detailed description of the device] [The purpose of the device] [Industrial applications]

The present invention mainly relates to a cushioning frame for packaging used for transporting a device such as a color printer to prevent damage, and is intended to improve productivity and contribute to cost reduction.

[Prior art]

A conventional cushioning frame used for transporting a color printer of this type has a rectangular box shape in order to be mounted on both ends of the color printer, and has an uneven shape on both ends of the color printer. -Symmetrical uneven shapes were provided to match. A conventional packaging cushion frame of this type has been manufactured by the following manufacturing method. That is, the manufacturing method is called wet molding method, and natural fibers (especially newspaper, magazine, corrugated cardboard, cardboard, etc.) such as waste paper, waste pulp, tree bark and meat are chopped into water. The mixture is mixed and dispersed to form a slurry, and the pulp fiber cut product slurry (hereinafter referred to as pulp slurry) is adsorbed by a suction dehydration to a mold having a water-permeable micropore surface of a required shape (hereinafter referred to as pulp fiber cut product). A fiber cut product (referred to as a fiber cut product) is formed, and then the fiber cut product is released from the mold and dried to produce a molded product.

[Problems to be solved by the device]

As described above, in the conventional technology, the shape of the target molded product is a rectangular box shape, and the flat area of the molding die is currently limited. I was only able to "take one" or "take two". This has the drawback of low productivity and high cost. The present invention achieves multiple times such as "two-piece" or "four-piece" with the same mold in one molding process without reducing the function as a cushioning frame for packaging, and high production. The purpose is to obtain the property and cost reduction.

[Constitution of device] [Means for Solving the Problems]

The present invention requires a pulp fiber shredded material slurry (hereinafter referred to as pulp slurry) prepared by dispersing pulp fiber shredded material (hereinafter referred to as fiber shredded material) such as waste paper and waste pulp material in water. When manufacturing a molded product of a substantially box-shaped buffer frame by suction dehydration in a mold with a water-permeable micro-pore surface, the buffer frame molded product conforms to the irregular shape of the adherend device Forming a concave-convex shell to form a buffer frame, and forming a set of a plurality of buffer frames so that a convex shape is formed on one side and a concave shape where the convex shape fits on the other side is formed in a planar state. It is constructed by forming on one side of each of the molded parts of the frame.

The most important configuration in the present invention is a plane shape of a molded product (hereinafter referred to as a molded product) of a buffer frame which is made by a wet molding method using pulp slurry as a material. One example thereof will be described in detail below with reference to the drawings. That is, in manufacturing a molded product, two molded products are made into a set, one is a molded product A, and the other is a molded product B. Each molded product A is shown in FIGS. 1 to 3. The molded product B is shown in FIGS. 4 to 6.

Both the molded product A and the molded product B have a substantially rectangular box shape as a whole, and form a concave-convex shell 1 that can be fitted to a buffer-required portion of a device as an adherend.

Then, when the molded product A and the molded product B are arranged in a planar state, a truncated pyramidal protrusion 2 is formed on the molded product A so that they are fitted and adjacent to each other. Creates a truncated pyramid-shaped concave shape 3.

In the process of molding, as shown in FIG. 7, the convex shape 2 of the molded product A and the concave shape 3 of the molded product B are fitted into each other, and the molded product C is placed so as to be juxtaposed in parallel with each other. Form. After molding, as shown in FIG. 8, the molded product A and the molded product B are separately used as a buffer frame. In addition, in the embodiment, the convex shape 2 and the concave shape 3 which are fitted to each other are each formed into a truncated pyramid shape, but the shape is not limited to this shape and may be a rectangle. As long as the side surface is flat and the area is small, the same effect can be obtained with any shape. In the embodiment, the molded product C is assumed to be a set of two pieces, but it may be a set of three pieces, a set of four pieces, or a plurality of pieces in short, but it may be a plurality of pieces. The object of the present invention can be achieved if it has the shape 2 and the entire plane area is as small as possible.

[Effect of device]

As described above, since the present invention has the convex shape and the concave shape that can be fitted to each other of the individual molded products to be manufactured, the flat area of the assembly is reduced, and the molded product can be molded in that state. By designing the molding die, the number of products produced in one step can be increased. For example, the molding die D shown in FIG. 9 has almost the same molding area as the molding die C shown in FIG. 7, but the molding E has no means for fitting with each other and reducing the area. There is no choice but to manufacture only product E. As described above, according to the present invention, even if the molding die has the same molding area as the conventional one, the number of productions in one process can be increased, so that the production efficiency is improved, the high productivity can be achieved, and the cost is significantly increased. It is possible to reduce the amount, and it is extremely effective in practical use.
