Description

  The present invention relates to a packing material for efficiently storing a ring-shaped part such as a handle for an automobile.

Conventionally, a ring-shaped part such as a handle for an automobile has a large space inside the part, and is very easy to be wasted in terms of packaging space, and is difficult to package. In the case of such a handle having a hub portion or the like protruding in the center, the handle is generally arranged in a vertically arranged manner.
However, in the case of packing by placing vertically, in order to pack so that the ring-shaped parts do not come into contact with each other, it is necessary to have a large gap between the parts at the time of packing work. For example, Patent Document 1 discloses an example in which the handle portion is overlapped in a plan view and stored horizontally to improve storage efficiency.

  In Patent Document 1, a plurality of buffer packaging materials (packaging materials), which are entirely made of a synthetic resin foam, are arranged in parallel at intervals in a container forming an outer case, and are shaped like a handle or the like. The arc rim part (handle body) of a part is accommodated in the left and right shock-absorbing packaging materials, and is supported so that one adjacent arc rim part overlaps the other arc rim part. The buffer wrapping material having a configuration that can increase the number of components arranged in the container and increase the storage efficiency is disclosed.

However, the conventional packaging of ring-shaped parts such as handles has the following problems.
That is, in the case of packing vertically, there is a problem that the part is damaged in a considerable amount, such as a dent in the support part, in order to support the weight of the part at the circular part on the outer periphery. And in order to reduce the damage received in the circular part of a ring-shaped part, the operation | work which packs a bag for every part generate | occur | produced, and the effort and time concerning packing were required.

Also, in Patent Document 1 which is a flat packaging, if the handle main bodies are stored in a stacked state in consideration of the storage efficiency, the load of each part is borne by the handle main body. Sometimes damage such as scratches occurs on the outer peripheral part (handle body) exposed on the surface, making it difficult to stack a large number of parts in a stacked manner.
Therefore, there is a need for a packaging material that can achieve a good balance between preventing damage to the ring-shaped component and improving the storage efficiency, and there is room for improvement in that respect.

  The present invention has been made in view of the above-described problems, and can perform packaging with improved storage efficiency without damaging the parts to be packaged, and also reduces labor and time during packaging. It is an object of the present invention to provide a packaging material capable of achieving the above.

In order to achieve the above object, in the packing material according to the present invention, the shaft body is connected to one end portion of the shaft body via the connecting body, and is stretched in a direction perpendicular to the axial direction so as to surround the shaft body. A plate-shaped packing material in which a plurality of parts to be packed having a protruding portion are packed flat in a posture in which the axial direction is in the vertical direction and stacked in the vertical direction, and at least a shaft is provided on the upper surface side. a plurality of accommodating portions for accommodating the part of the body, and the lower surface side downward protrusion is provided protruding downward at a position corresponding to the accommodating portion of the upper surface, a plurality of accommodating portions, overhanging the object to be packaged parts The parts are not accommodated, and the overhanging portions of adjacent packaged parts are overlapped with each other in plan view, and the overhanging parts of adjacent packaged parts are formed in a position that maintains a non-contact state. The parts are housed in the housing part and are formed by downward convex parts provided in the upper stage. Retained, ChoIzurubu is on the same circumference are continuously or partially configured, housing part to be packed components are accommodated, projecting portion of the object to be packed parts adjacent housed in the housing portion the distance between the centers of is characterized Rukoto the shorter position than the diameter of the circle formed by the projecting portion, and are formed at positions displaced from each other in the vertical direction.

In the present invention, adjacent parts to be packed housed in each of the plurality of housing portions are in a state where the overhanging portions overlap each other in a plan view, and the overhanging portions are kept in a non-contact state. It can be accommodated without contact. And since the shaft of the packaged part accommodated in the lower packaging material is supported by the downward convex portion of the stacked upper packaging material, the load of the packaging material containing the upper packaging component Is to be borne by the shaft body of the lower packaged part, and the projecting portion projecting in the direction orthogonal to the axial direction so as to surround the shaft body can be packed without damage. Therefore, for example, when the part to be packed is an automobile handle or the like, even if it is a ring-shaped part where the handle body (overhanging portion) of the outer peripheral portion is exposed on the surface when the vehicle body is mounted, Excellent packing can be performed without damaging the handle without applying a load.
Moreover, since it can be stored flatly and adjacent overhang | overhang parts can be stored, storage efficiency can be improved and the accommodation quantity of to-be-packaged parts can be increased.

In addition, in the state where the overhang portions of the parts to be packaged are overlapped in plan view, the overhang portions have different heights in the vertical direction, so that there is a step between them, so that they are accommodated without contacting each other. be able to.

Further, in the packing material according to the present invention, the shaft body is a bottomed cylindrical body whose one end is open and the other end is closed, and the downward convex portion is fitted inside the cylindrical body. preferable.
With such a feature, since the downward convex portion of the upper packaging material is fitted inside the cylindrical body that forms the shaft of the lower packaged part, a horizontal displacement occurs between the two. And maintain a stable posture.

Moreover, in the packing material which concerns on this invention, it is preferable that the lower surface of a downward convex part is a shape along the uneven | corrugated shape of the upper surface of a shaft body.
In the present invention, since the lower surface of the downward convex portion and the upper surface of the shaft body of the packaged part are securely in contact with each other without any gap, the load applied to the stacked packaging material on the upper stage side is lowered via the downward convex portion. It is possible to reliably bear the burden on the upper surface of the shaft body of the part to be packed housed in the side packing material.

Moreover, in the packaging material which concerns on this invention, it is preferable that the accommodating part is formed with the recessed part for fitting the bottom face of a shaft.
In this case, since the bottom surface of the shaft body of the packaged part is accommodated in a state of being fitted into the recessed part of the accommodating part, the lateral displacement is prevented and the holding state of the packaged part is stabilized. The position of the packaging component is not shifted and does not come into contact with the surrounding area of the packaging material, so that more reliable packaging can be realized.
In addition, since the top surface of the recessed portion and the bottom surface of the packaged part are in contact with each other, the packaged component accommodates the load of the stacked upper packaging material in the lower recessed portion via the downward convex portion. When received on the upper surface of the shaft body, the load can be transmitted from the bottom surface of the packaged part to the lower packaging material.

Moreover, in the packing material which concerns on this invention, it is preferable that a support | pillar part is further provided between several downward convex parts, and when a packing material is accumulated, a packing material is supported by a support | pillar part.
