DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer tray set and a transfer packing set, and more particularly, to a transfer tray set and a transfer tray set for packing conveyed articles such as electric product parts, automobile parts, and machine parts. Regarding the packing set.

[0002]

2. Description of the Related Art Conventionally, electric parts such as cathode ray tubes (CRTs) for displays such as televisions and personal computers, and automobile parts have been housed in wooden boxes or steel cases for transportation. However, if a wooden box or the like is used, a buffering and fixing material such as styrene foam for holding the conveyed article is additionally required, and the cost is high. Therefore, packing materials made of cardboard or styrene foam have recently been used. These packing materials include a box-shaped material for storing the goods therein and a tray-like material for packing the goods in a stacked state by using the compressive strength of the goods. For example, as a packaging material for a cathode ray tube, a package has been proposed in which a cathode ray tube is sandwiched from above and below by a cardboard pad or tray, and these are stacked and conveyed (Japanese Patent Laid-Open No. Sho 6).
0-158075, JP-A-61-60484, and JP-B-56-42222). The conveyed goods packed by such a packing material are loaded on a pallet made of metal or another material and transported by a transportation means such as a wagon.

[0003]

In the above-mentioned packing material made of styrene foam or corrugated cardboard, there is a possibility that shavings of styrofoam or paper dust of corrugated cardboard may adhere to a conveyed material such as a cathode ray tube, thereby deteriorating the quality. In addition, since these packing materials are one-way disposables, waste is generated every time the conveyed goods are conveyed to the destination, so that there is a problem that disposal processing is troublesome and costs are increased. . To solve such disposal problems,
Although it is conceivable to repeatedly use the packing material, when returning the package in an empty state after the conveyance, the packing material such as a cardboard is bulky and the transportation efficiency is poor. In particular, Styrofoam packaging materials are formed thick to ensure strength enough to withstand transportation, so the stacking height increases both when transporting conveyed items and when returning the packaging materials, resulting in increased transport efficiency. Was bad.

Further, when a conveyed product packed with a packing material made of cardboard or styrofoam is loaded on an existing resin pallet, it is slippery and sufficient stability cannot be obtained. In addition, metal pallets are heavy and are difficult to handle. If a pallet made of corrugated cardboard or a wooden pallet is used, paper debris or wood debris may adhere to the conveyed material, leading to a deterioration in quality.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transport tray set that can reliably maintain the quality of a transported product, can solve the waste disposal problem, and can ensure excellent transport efficiency. Another object of the present invention is to provide a transport packing set that can reliably maintain the quality of a conveyed product, can eliminate waste disposal problems, ensure excellent transport efficiency, and can transport conveyed products in a stable state. It is in.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a transport tray set for sandwiching and holding a transported object from above and below,
It is provided with a holding recess for fitting the upper part of the conveyed object, and a resin upper tray capable of being stacked with the holding recesses fitted to each other, and a holding concave for fitting the lower part of the conveyed article, and A lower tray made of a resin that can be stacked with the holding recesses fitted to each other, and the upper tray and the lower tray are formed by molding a molten resin into a uniform shape using a male and female mold. It is characterized by being.

[0007] In the present invention, the lower part of the conveyed article is inserted into the holding recess of the lower tray, the upper tray is disposed on the conveyed article, and the holding recess is inserted into the upper part of the conveyed article. Is clamped from above and below. In this way, the tray packages in which the transported material is sandwiched between the lower tray and the upper tray are stacked in a desired number of stages as necessary. That is, on the upper tray constituting the lower tray package, another lower tray is arranged, and in the same manner as the lower tray package,
The transported article and the upper tray are arranged on the lower tray, and the transported article is sandwiched between a pair of trays to form an upper tray package. Such a tray package is transported to the destination by means of a freight car or the like, but the transported articles are fitted into the holding recesses of the upper tray and the lower tray, so that a stable posture is maintained in a predetermined posture. Transported by.

In addition, since the upper tray and the lower tray are made of resin, no waste such as paper dust or shavings is generated, so that the quality of the conveyed material due to the adhesion of the waste can be reliably prevented. Further, the resin tray can sufficiently secure the strength enough to withstand transportation even if the tray is not as thick as the styrene foam tray, so that the transport space required for the tray can be reduced, so that excellent transport efficiency can be secured.

After the conveyed goods are conveyed to the destination, the upper trays and the lower trays are stacked by fitting the holding recesses of each other, and are returned by various transportation means in that state, and are again conveyed. Used for packaging. As described above, the upper tray and the lower tray made of resin have excellent durability that can withstand repeated use, so that it is not necessary to discard each time the sheet is transported, so that the problem of tray disposal can be solved. Further, since the upper tray and the lower tray are stacked with the holding recesses fitted, the stacking height, that is, the nesting height can be reduced, and the space required for the trays is reduced, so that the transportation at the time of return is performed. Efficiency can be significantly improved and space is not required during storage.

In addition, since the upper tray and the lower tray are formed by molding a molten resin into a fixed shape using male and female molds, excellent dimensional accuracy can be obtained. Since the control can be performed, it is possible to reliably prevent the load from being shifted. Further, since the thickness of the squeezed and deformed portion is not reduced as in the case of a vacuum formed product, a sufficient strength that can withstand repeated use can be secured.

The shapes of the holding recesses of the upper tray and the lower tray may be appropriately set in accordance with the shapes of the upper and lower portions of the conveyed product. The upper and lower trays are
Desirably, they have substantially the same shape as each other, and are formed so that they can be stacked in a state where the respective holding recesses are fitted to each other. If the upper tray and the lower tray can be stacked with the holding recesses fitted to each other, the space for transporting and storing the trays can be further reduced.

Further, each of the upper tray and the lower tray has a reinforcing frame portion along the outer periphery, and the reinforcing frame portion preferably has a shape that can be fitted to each other when the trays are stacked. By providing a reinforcing frame along the outer periphery of each tray, the rigidity of the tray can be increased, and the deformation of the tray, especially the deformation of the tray due to the load of the load, can be prevented. Excellent stability can be secured. Further, when stacking the trays, the upper and lower trays can fit the reinforcing frame portions with each other, so that the nesting height of the trays can be reduced.

It is desirable that each of the upper tray and the lower tray has a hand-held portion. In this way, excellent handling properties can be obtained when carrying or stacking the trays.

[0014] It is desirable that the upper tray and the lower tray are provided with engaging portions that can be engaged with each other on the surface opposite to the surface on the holding concave side. In this case, when stacking a plurality of tray packages consisting of an upper tray, a conveyed product, and a lower tray, specifically,
When the lower tray with the holding concave side facing up is placed on the upper tray with the holding concave side facing down, the engaging portions of the upper tray and the lower tray are The engagement prevents these trays from being displaced from each other, thereby ensuring excellent stability.

Further, it is preferable that an elastically deformable protrusion for receiving a conveyed material is formed at the bottom of each holding recess of the upper tray and the lower tray. If such a protrusion is provided, even if the conveyed object falls while being sandwiched by the upper tray and the lower tray, the shock due to the fall can be absorbed by the elastic deformation of the protrusion, so that the shock is directly conveyed. It can be prevented from being transmitted to the object, and the conveyed object can be reliably protected. In any case, since the tray is molded from a molten resin into a fixed shape using male and female molds,
The shape and thickness of each part including the holding concave part and the protruding part can be freely designed, and the dimensional accuracy can be improved.

On the other hand, the present invention is a transport packaging set for holding a transported object sandwiched from above and below, provided with a holding recess for fitting the upper or lower part of the transported article, and the holding recesses are fitted to each other. The tray includes a resin tray that can be stacked in a stacked state, and a resin pallet with a holding recess approximately the same as the tray on the top surface. Molded product,

If necessary, another tray is placed on the pallet package in which the conveyed material is sandwiched between the pallets and trays, that is, on the tray, and the lower part of the conveyed product is inserted into the holding recess. Then, the holding recess of another tray is fitted into the upper portion of the conveyed object. In this way, a desired number of layers of the tray package in which the conveyed material is sandwiched between the pair of trays are stacked on the pallet package described above, and a package unit is assembled. The package units in which the tray packages are stacked on the pallet package are stacked in a desired number of stages during transportation or storage. Such a package unit is transported to the destination by a transportation means such as a freight car, but the transported product is fitted into each holding recess of the pallet and the tray, or each holding recess of the pair of trays, It is transported in a stable state with the predetermined posture.

Further, since the tray and the pallet are made of resin, no waste such as paper dust and shavings is generated, so that the quality of the conveyed product due to the adhesion of the waste can be reliably prevented. Furthermore, resin trays and pallets can secure sufficient strength to withstand transportation even if they are not as thick as those made of styrofoam.Thus, transport space required for trays and pallets is reduced, ensuring excellent transport efficiency. it can. In addition, since the pallet directly holds the conveyed object by the holding concave portion, the conveyed object is securely held without slipping, so that the pallet can be transported in a stable state.

After the conveyed goods are conveyed to the destination, the trays are stacked on the pallet, and the holding recesses are fitted to each other. In this state, the conveyed goods are returned by various transportation means and used again for packing the conveyed goods. . As described above, the resin tray and the pallet have excellent durability that can withstand repeated use, so that they do not have to be discarded every time they are conveyed, so that the disposal problem can be solved and resources can be saved. In addition, resin pallets can be made lighter than existing metal pallets, so that excellent handling properties can be obtained. further,
Since the trays and pallets are stacked with the holding recesses fitted together, the stacking height, that is, the nesting height, can be reduced, and the space required for the trays and pallets is reduced. It can be significantly improved and does not take up space during storage.

The lower surface of the pallet described above may be formed flat, but it is preferable that the pallet has the same holding recess as the upper surface on the lower surface. When the holding recess is formed on the lower surface of the pallet, when stacking the package units including the pallet package and the tray package described above, the pallet of the upper package unit is placed in the uppermost tray of the lower package unit. Can be used for In other words, the uppermost tray of the lower packing unit is fitted with the holding recess on the lower surface of the pallet located at the lowermost layer of the upper packing unit, so that the uppermost tray of the lower packing unit is inserted into the upper part of the uppermost conveyed product of the lower packing unit. In addition to being omitted, it is possible to prevent displacement of the package units. Furthermore, since the upper and lower surfaces of the pallet have the same holding recess, the upper and lower parts of the pallet can be molded separately and integrated using the same male and female molds to simplify the pallet. It can be manufactured at low cost.
