Description

[Detailed Description of the Invention] The present invention relates to a cushioning partition material for packaging used when stacking equipment.

Conventionally, when transporting a large number of equipment or parts, one or several of them are secured with styrofoam or pulp mold to provide cushioning, each is packed in a cardboard box, and then stacked in several stages on a pallet. The method used is to use a heat-shrinkable plastic film to integrate and fix the whole thing by its shrinkage force, and then cover it with an outer box and then shrink the band. However, in such cases, it takes a lot of labor and time to wrap the equipment in cushioning materials and cardboard boxes, which increases packaging costs. It used to take a lot of trouble to open the cardboard box.

The present invention was proposed in order to overcome the drawbacks of conventional packaging for this type of equipment.
Next, this will be explained with reference to the embodiment shown in the drawings.
A is a cushioning partition material for packaging, which is manufactured from pulp mold material (used paper such as newspapers, magazines, cardboard scraps, etc.) or a slurry stock solution made from pulp using a wet method using a paper mold with a paper screen and then dried. It consists of a substrate a having a downward facing edge e on the outer periphery, and a plate-shaped reinforcing plate c made of double-sided cardboard, plywood, etc., adhered to the lower side of the substrate via urethane resin b, etc. , the board a is provided with a recess 2 (FIGS. 2 and 4) formed on the upper side so that the equipment to be packaged B, for example, the lower end frame 1 of a motor, can be placed therein, and the lower side opposite to this is provided with a recess 2 (see FIGS. Concave and convex shaped parts 4 and 5 formed so as to be covered in a saddle shape on the body 3 of the motor m which is separate from the device, that is, the motor m.
(Figures 3 and 5) A large number of buffer units d... each made of pulp mold with protrusions are provided at appropriate intervals. The reinforcing plate c is bonded to the lower side of the substrate a through a urethane resin b or the like, except for the uneven portions 4 and 5 of the buffer unit d formed on the substrate a. As shown in the drawings (FIGS. 4 and 5), the shaped portions 4 and 5 protrude downward from the punched holes c' of the punched reinforcing plate c.

The equipment to be packaged B is not limited to the motor m, but may be any other equipment, and the recessed portion 2 and uneven portions 4 and 5 of each buffering unit d of the partition material A may vary depending on the external shape of the equipment. It may be changed as appropriate. The board a shown in Fig. 1 has a buffer unit d.
For example, nine pieces are provided, but as shown in FIG. 10, these pieces can be further connected to increase the number of pieces.

In the embodiment shown in the drawings, the pulp mold substrate a has a downward edge e around its outer periphery. Of course, the plate-shaped reinforcing body c may be directly bonded.

The plate-shaped reinforcing plate c used in the present invention is
Any plate-shaped material such as fiberboard, plywood, particle board, plastic board, or corrugated sheet may be used as long as it supports the pulp mold, is light, and provides the rigidity of the packaging partition material of the present invention as a whole. Adhesives are used to bond and integrate the above-mentioned pulp mold and plate-shaped reinforcing material, and there are two types of adhesives: planar adhesives and three-dimensional adhesives. Planar adhesives adhere only to the applied surface, whereas three-dimensional adhesives foam to form a foam and adhere three-dimensionally. Planar adhesives include natural products such as starch and casein, thermoplastic resins such as vinyl acetate resin and polyvinyl alcohol, thermosetting resins such as epoxy and phenolic resins, elastomers such as butadiene, styrene, and neoprene, and phenolic vinyl butyral. Resin, mixed resin such as phenolic neoprene, etc. can be used. As the three-dimensional adhesive, polyurethane foam, polyisocyanurate foam, urea foam, etc. are used.

In the present invention constructed as described above, when packing equipment to be packaged using this as a cushioning partition material for packaging, the pallet P is placed at the lowest position as shown in Fig. 11.
A partition material that has only a concave portion 2 on the upper side for placing a packaged device, such as a motor stand 1, and lacks uneven portions 4 and 5 that cover the lower motor body in a saddle shape.
A' is placed on the partition material A', and a first row of equipment to be packaged, such as a motor m, is placed on top of the partition material A'. Another second row of packaged equipment motor m is placed in the recess 2 above it, and the partition material A is further placed on top of it in the same manner as before. Separate the motors in several rows one after the other, stack a plate-like material C such as strong fiberboard or plywood on top, and cover the entire material with a sheath box H made of cardboard, etc., and then tighten this with a band. Either it is packed for land transport, or the packaged equipment motors m, etc. are stacked in several tiers as described above via the partition material A, and the whole is shrink-wrapped with heat-shrinkable film, and then the whole is made into a sheath box made of cardboard or the like. After wrapping H, it may be sealed with a metal band or wire and packaged for overseas export.

Therefore, the shock-absorbing unit d of each partition material A is made of pulp mold, so it has extremely high shock-absorbing properties, and the reinforcing plate c is also relatively light, allowing the equipment to be packaged to be fixed and packed without shaking, and moreover, compared to conventional methods. This method has the effect that a large number of devices can be packaged and transported extremely economically and inexpensively without requiring the laborious labor and time required.
