Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a corrugated board packaging structure applied to collect and package a plurality of equipment parts such as a pump unit of a compressor for transportation.

[Prior Art] Generally, when relatively heavy equipment parts such as a compressor are stacked and stored in an outer box of a corrugated board for collective packing, the weight of the upper equipment parts is usually added to the lower equipment parts. The vertical compressive load must be supported inside the package to prevent

Conventionally, in this type of corrugated cardboard packaging, an intermediate partition plate made of wood, styrofoam, corrugated cardboard, or the like is used as a support structure for supporting the vertical compressive load of equipment parts. There is a device having a structure in which the device parts are stacked so that the device parts are packaged so as to receive a vertical compressive load.

[Problems to be Solved by the Invention] However, in such a conventional corrugated board packaging structure, sufficient compressive strength cannot be obtained if the inner partition plate is formed of styrofoam or one thin corrugated board.
It cannot support the compressive load due to the weight of equipment parts,
Stacking becomes unstable.

In addition, as a device part, for example, when a compressor pump unit is stacked and packed in a corrugated cardboard outer box in multiple stages, a rotating shaft portion protruding vertically above and below the center portion of the cylinder block that is the main body portion of the pump unit is used. If the package is packaged in contact with the rotating shafts of the adjacent pump units or in contact with the partition plate, the accuracy of the rotating shafts is likely to be incorrect due to vibration or shock during transportation.

Moreover, it is necessary to devise to prevent the load from being directly applied to the rotating shaft part, etc., in the case of equipment parts that have a unique shape with a large diameter main body part with the rotating shaft part inserted in the center of the cylinder block. In addition, the height of the entire outer box is bulky and it is difficult to pack and store it in a compact size.In addition, when the outer box is bound by a band, the strength of the top corrugated board holding plate is small, There is a problem that the central portion is lifted up by the tightening force of, and in particular, an external force acts on the uppermost stacked device components to easily damage them.

[Object of the Invention] The object of the present invention is to compactly pack and store the equipment parts for stable stacking and transportation, and to maintain the accuracy of the shaft protruding from the main body of the equipment parts and to tie them together with a band. An object of the present invention is to provide a corrugated board packaging structure capable of reliably preventing the equipment components stacked in the uppermost stage from floating.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention stacks a plurality of corrugated cardboard middle trays in a corrugated cardboard outer box, and a corrugated board partition plate in each middle tray. In the upper and lower storage space sections, which are divided into a plurality of two upper and lower stages, the top-shaped device parts with the shaft portions protruding vertically in the central portion of the main body section are laterally displaced from each other by a half pitch, and By vertically stacking the device parts upside down and holding the body part of the device part by the upper and lower partition plates, the shaft part protruding from the body part is placed and stored in a levitationally supported state. On the other hand, on the upper part of the partition plate divided into the uppermost middle tray, an upper presser plate for pressing the main body of each upper erect device component from above is incorporated, and the upper presser plate While placing the top plate on the top, A corrugated cardboard reinforcing plate is provided at a central portion between the top plate and the upper pressing plate, and the cardboard reinforcing plate which forms the upper pressing plate is adhesively held and interposed.

[Operation] That is, according to the present invention, by adopting the above-mentioned structure, the strength of the partition plate made of corrugated board, the middle tray and the outer box can be improved, so that an external load is not applied to the device parts. The whole is compact and easy to pack and store, which enables stable transportation.

Further, since the shaft portion protruding from the main body of the equipment component is accommodated in a floating support state, the shaft portion of the equipment component comes into contact with the shaft portion of another adjacent equipment component or contacts the partition plate. As a result, it is possible to prevent the accuracy of the shaft portion of the device component from being deviated due to vibration or shock during transportation as in the past.

Further, since the corrugated board reinforcing plate is arranged in the center between the top plate and the upper pressing plate, the tightening force of the band when binding the outer box acts on the center part and the average is applied to the whole. Therefore, it is possible to prevent the floating of the central portion as in the conventional case.
