Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a cardboard packing structure applied to packing packed articles such as compressors.

[Prior Art] Generally, for example, when a relatively heavy packaged product such as a compressor is stacked and stored in an outer box of a corrugated cardboard for packaging, the upper packaged product is usually added to a part of the lower packaged product. The vertical compression load must be evenly distributed and supported inside the package so that the weight of the load is not biasedly applied, or this load must be released by packing material.

On the other hand, in this way, when packing and storing packed products such as compressors that are comparatively heavy and have a high center of gravity and have a small bottom area, the packed products can be laterally or longitudinally packed. In order to prevent movement or tilting, a lateral shake prevention plate is interposed as necessary.

Conventionally, a corrugated cardboard packing structure of this type, in particular, a lateral shake prevention plate used to prevent the packed articles from moving or tilting in the lateral direction or the front-rear direction,
Some have a configuration as shown in the figure.

Such a conventional lateral shake prevention plate (20) is formed of a flat plate material (21) such as styrofoam.
In the present situation, 1) is provided with a number of punched holes (22) into which packaged items are fitted, and the strength is maintained by giving a certain thickness.

[Problems to be Solved by the Invention] However, in the lateral shake prevention plate (20) used in the above-described conventional cardboard packing structure, the contact area of the peripheral end surface (21a) that contacts the inner surface of the outer box of the cardboard Is small, and because many punched holes (22) are not formed, sufficient strength cannot be obtained, so not only the workability of assembling at the time of packing or unpacking is poor, but also the packaged product is not affected by the inertial force received during transportation. When rocked, the peripheral parts of the lateral shake prevention plate (20) may be bent due to the effects of loads such as compression, tension, bending, etc., and if there is no stopper on the inner surface of the packaged product or outer box, vibration during transportation will occur. For example, it is easily displaced and is not fixed at a predetermined built-in position, which makes the inside of the package unstable during transportation.

On the other hand, when wood is used to prevent rolling and slippage, not only is it costly to dispose of the waste material after unpacking, but if it is transported or stored for a long period of time, the moisture content in the wood will be lost. There is a risk that the strength of the cardboard will be reduced by impregnating it into the box or other partitioning material of the cardboard, and in order to prevent this, a wood drying process is required in advance, resulting in high costs. Become.

Further, it is possible to increase the thickness of the base material in order to increase the strength of the lateral shake prevention plate (20), but this causes a problem that the material cost becomes high and the cost becomes high.

[Object of the Invention] The present invention has been made under the circumstances described above. The purpose of the present invention is to prevent a horizontal shake and a shift of a packaged product and to support a vertical compression load. It is an object of the present invention to provide a cardboard packing structure that is inexpensive and surely fixes the inside of the packing so that transportation can be performed stably by devising means.

[Means for Solving Problems] In order to solve the above-mentioned problems, the present invention interposes a lateral shake prevention plate in a cardboard outer box in which the packaged products are stored, which prevents lateral vibration of the packaged products. In the cardboard packaging structure described above, the lateral vibration preventing plate is formed of a cardboard member, and a peripheral edge portion of the cardboard member that abuts the inner surface of the cardboard outer box is bent to have an L-shaped cross section, and at the storage portion of the packaged item, The pad is formed by incorporating a columnar pad as a dummy of the packaged product, and the pad is formed by winding a single-sided cardboard member in a spiral shape to form a columnar shape, and a flute of the single-sided cardboard member. The direction of is the axial direction of the cylinder.

[Operation] That is, according to the present invention, with the above configuration,
Since the lateral shake prevention plate is formed by bending the peripheral edge portion of the cardboard member, which abuts against the inner surface of the cardboard outer box, to have an L-shaped cross section, the lateral shake prevention plate has a U-shaped cross section, so that the strength against bending is increased. Since it is possible to improve the workability of assembling at the time of packing or unpacking and can reduce the thickness of the cardboard,
The material cost can be reduced, and the cost can be reduced.

Further, since the contact area of the peripheral end surface of the lateral shake prevention plate with the inner surface of the cardboard outer box can be increased, when the packaged product swings due to the inertial force received during transportation, each of compression, tension, bending, etc. Even if a load is applied, it is possible to prevent bending of the peripheral portion of the package and to prevent displacement due to vibration during transportation, etc. As a result, the inside of the package is securely fixed and stable transportation is achieved. It becomes possible to do.

Furthermore, since a cylindrical pad as a dummy for the packaged product is installed in the storage part of the packaged product, the vertical compression load of the packaged product during packing is supported by the padding, and the horizontal shake Together with the prevention plate, it is possible to prevent deviation due to vibration during transportation, etc., and the inside of the package can be more securely fixed and stable transportation can be performed.

Furthermore, since the pad is formed into a columnar shape by spirally winding it with a single-sided cardboard member, and the flute direction of the single-sided cardboard member is in the axial direction of the cylinder, the pads on the upper and lower surfaces relative to the mating member are Large contact area,
Large compressive strength can be obtained without using metal, wood, etc., and the basis weight of the liner and the core, the height of the flute or the inner and outer diameters can be easily changed according to the required compressive strength. Optimum design of cost and strength is possible.

Moreover, the material cost of the pad is reduced by using the single-sided cardboard member, and the pad can be easily manufactured, and the assembling work at the time of packing and the waste material disposal work after unpacking can be performed without trouble.

[Embodiment] Hereinafter, the present invention will be described in detail with reference to an embodiment shown in FIGS. 1 to 6.

FIG. 1 schematically shows a cardboard packing structure according to the present invention, in which (1) is a packing body. This packing body (1) includes, for example, a pallet (2) that serves as a pedestal that facilitates loading and unloading work by a forklift truck, a tray (3) placed on the pallet (2), and the tray (3). ) And an outer box (4) loaded on the upper part of the outer box, and inside the outer box (4), as shown in FIG. A plurality of relatively heavy packages (A), such as compressors stacked in layers ...
Are stored and packaged, and the upper part of each of the upper and lower packaged products (A) has a horizontal shake prevention plate (7).
On the other hand, a pad (8) which also functions as a horizontal shake prevention plate is laid at the bottom of each packaged product (A) while being held by
These pallets (2), trays (3), exterior boxes (4),
The intermediate partition plates (5) and (6), the lateral shake prevention plate (7), and the pad (8) are all made of cardboard bonded to each other in a plurality of layers.

Further, (9) in the figure is the packaged product between the upper and lower intermediate partition plates (5) and (6), which is held by a pair of upper and lower horizontal shake prevention plates (7) and (8) as a dummy of the packaged product (A). It is a pad arranged in a plurality of places in the storage part of (A).

Each of the pads (9), as shown in FIG. 3, which has a obtained by forming into a cylindrical shape by winding bonded to one side cardboard member (10) in a spiral like configuration, one side thereof cardboard member (10 ) The direction of the flute is set to the axial direction of the cylinder, so that even if the quantity of packed items does not reach a certain number, it is biased to a part of the lower packed item (A) ... The vertical compression load is evenly supported by the members inside the package and the packaged product so that the weight of the packaged product (A) ... Is not applied.

Each pad (9) described above has a contact surface that increases according to the compressive strength of the mating material that contacts the upper and lower liners, that is, the upper and lower partition plates (5) and (6) made of cardboard. The corrugated cardboard member (10) is wound so that the spiral winding width becomes dense from the inner diameter to the outer diameter,
By limiting the directionality to only the top and bottom, the assembly work during packing can be done easily, and the basis weight of the liner and core and the flute height can be adjusted according to the required compression strength. Alternatively, it is possible to easily change the inner and outer diameters, which enables optimal design of cost and strength.

Furthermore, the above-mentioned lateral shake prevention plate (7) is interposed to prevent the stacked packaged products (A) from moving or tilting in the lateral direction or the front-rear direction. As shown in FIG. 5 and FIG. 5, for example, the peripheral portion (71a) of a rectangular cardboard member (71) is bent into an L-shaped cross section, and the bent portion is fixed with staples (72), so that the entire cross section is It is configured to have a letter shape, and its flat surface portion is provided with a large number of punched holes (73) into which packaged products are fitted.

That is, according to the above configuration, when the packaged articles (A) are stacked and stored in the outer box (4), the lateral shake prevention plate (7) is incorporated into the outer box (4) and punched out. By fitting the upper part of the packaged product (A) into the hole (73),
The package product (A) is prevented from lateral vibration, and as shown in FIG. 6, the contact area between the bent peripheral end surface of the lateral vibration prevention plate (7) and the inner surface of the outer box (4) is increased. As a result, when the packaged product (A) swings due to the inertial force received during transportation, even if loads such as compression, tension, and bending act on the packaged product (A), bending of its peripheral portion and vibration during transportation occur. It is possible to prevent the shift due to the above.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
