Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a corrugated cardboard packaging structure that is applied to packaging and transporting equipment parts such as compressors, for example.

[Prior Art] Generally, when relatively rough equipment parts such as compressors are stacked and stored in a cardboard outer box for collective packaging, the equipment parts on the lower tier are usually stacked with the equipment parts on the upper tier. The compressive load in the vertical direction must be supported inside the package to prevent stacking.

Conventionally, in this type of cardboard packaging, a partition plate made of wood, styrofoam, or cardboard is used as a support structure to support the vertical compressive load of one device component, and this partition plate is attached to an outer cardboard box. Some devices have a structure in which a single device component is packed in such a way that it receives a compressive load in the vertical direction by being placed on top of device components stacked in a container.

[Problems to be Solved by the Invention] However, in such conventional cardboard packaging structures, if the partition plates are made of styrene foam or a single thin piece of cardboard, sufficient compressive strength cannot be obtained. , it is not possible to support the compressive load due to the weight of the equipment parts, and the stacking becomes unstable.In particular, the accuracy is easily lost due to shocks such as compressor pump units, and the center of the cylinder block For equipment parts that have a unique top-shaped head with a large diameter through which the rotating shaft is inserted, it is necessary to take measures to prevent loads from being applied directly to the rotating shaft, etc. The overall height is bulky, making it difficult to pack and store compactly.

In addition, if wood is used in combination with the partition board, if it is transported or stored for a long period of time, the moisture contained in the wood may impregnate the outer cardboard box, inner tray, or other cardboard holding members. Not only is there a risk of reducing the strength of the cardboard itself, but if the packaged product is easily rusted,
There was a problem that the equipment parts were easily rusted.

[Object of the Invention] The present invention has been made under the above circumstances, and its purpose is to provide a method that allows equipment parts to be packed and stored in a compact manner for stable stacking and transportation, and to provide a reliable method. An object of the present invention is to provide a corrugated cardboard packaging structure in which rust prevention measures can be taken.

C Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention stacks a plurality of cardboard inner trays in a corrugated cardboard outer box, and installs a corrugated cardboard partitioning plate in each of the inner trays. In each of the upper and lower storage spaces, which are partitioned into two upper and lower levels through the intermediary, top-shaped equipment parts each having a large diameter main body are alternately stacked vertically upside down and shifted by a half pitch in the lateral direction. An intermediate presser is installed and stored in a supported state on the rl, and is placed on the upper part of the assembly partition plate partitioned into each of the middle trays except for the uppermost middle tray, and presses down the main body of each of the upper stage equipment components from above. It has a structure that incorporates a plate.

In this case, the upper and lower two-stage partition plates assembled in each middle tray except the top middle tray are assembled with a flat horizontal partition plate and are assembled perpendicularly to the horizontal partition plate and are mutually connected. U-shaped vertical partition plates of different heights on opposing walls are formed and stacked at two different heights, and each of the horizontal partition plates is inserted into each of these vertical partition plates from above, and assembled, In addition, the horizontal partition plate is inserted from below into the vertical partition plate that forms the upper partition plate in the middle tray of the top tier, and the horizontal partition plate is inserted into the tall inner wall side of the vertical partition plate. It is preferable to assemble a reinforcing partition plate.

As the intermediate holding plate, rod-shaped holding members made of foamed synthetic resin are placed in parallel at a predetermined interval apart from the center of the main body of the device component and adhered to the back side of the corrugated board. As a presser plate, rod-shaped presser members made by folding cardboard into the lower surface of the corrugated pole board are removed from the center of the main body of the device component, arranged in parallel at a predetermined interval, and glued together. It is preferable to use one formed by adhering a cushioning material made of synthetic resin.

In addition, when storing equipment parts in each middle tray, it is preferable to cover each equipment part stored through a partition plate with a waterproof material, and to wrap these equipment parts as a whole in an aluminum sheet. .

[Function] That is, the present invention has the above configuration,
Because the strength of the cardboard partition board, inner tray, and outer box is improved, the entire device can be easily packed and stored in a compact manner so that external loads are not applied to the equipment components, which allows for stable transportation. becomes possible.

In addition, each device component is wrapped in waterproof material, and the entire device component stored in the middle tray of each tier is wrapped in an aluminum sheet, which prevents the device components from rusting. can be done reliably.

At the same time as being placed and stored, on the upper part of the assembly partition plate partitioned into each of the middle trays except for the uppermost middle tray.

While incorporating an intermediate holding plate that presses the main body of each equipment component on the upper tier from above, the main body of each equipment component on the uppermost tier is attached to the upper part of the assembly partition plate partitioned in the middle tray of the uppermost tier. The structure incorporates an upper presser plate that presses from above, which improves the strength of the partition plate, inner tray, and outer box made of one corrugated cardboard, and prevents external loads from being applied to the equipment parts. Since the entire container can be packaged as a compact I-, stable transportation can be carried out.

In addition, individual equipment parts are wrapped in waterproof material, and the entire equipment part stored in the middle tray of each tier is wrapped in an aluminum sheet. This has the excellent effect of reliably preventing sticking.
