Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for laminated packaging of articles using partition plates having plate-like rigidity in integrated packaging of equipment, glass containers, container-filled products, etc., and shipping packaging. Regarding. This packaging method is particularly effective in cushioning and fixing the packaged items, and can be used in a wide range of applications for unit load cargo.

[Conventional technology]

With the increase in logistics, integrated packaging formats have been adopted from the perspective of rationalizing transportation and reducing costs, and progress has also progressed to the mechanization of cargo handling using unit load systems. These methods stack the products on a loading platform to package them as a whole, and then package the products together into a unit. Even for irregularly shaped or fragile products, this can be done in multiple stages. Packaging is done in a stacked manner. Figure 1 (a), (b), and (c) show this situation. After the goods are stacked on the pallet through partition plates for cushioning and fixing, and a protective plate such as plywood is placed on the top layer. ,
The whole is fixed together using heat-shrinkable plastic film, etc., and the band is tightened after covering with the outer box. It is also common practice to line up multiple stacks of items in rows or months next to these items to form a single box.

It is necessary to provide a recess that fits the shape of the article in the partition plate for buffering and fixing used in such integrated packaging.
Conventionally, two types of pulp molds molded into the upper and lower shapes of the article are used as such partition plates, as shown in FIG. 1 (a), and a cardboard box is used between each pulp mold, or a As shown in Figure 1 (opening), plastics such as urethane foam are used between two types of cardboard processed into the upper and lower shapes of the product.Furthermore, materials such as wood and metal are used. Molded and processed products are also used.

When using these molded partition materials, the cost of the partition material itself is high, and the packaging and packaging must be done manually, resulting in poor efficiency. Also, when disposing of used partition materials, urethane Plastics such as foam have drawbacks such as problems with incineration.

[Problems to be solved by the invention]

The product of the present invention eliminates the drawbacks found in the above conventional partition materials,
Among the functions required of partition materials, in particular, it enables work on packaging lines equipped with automated systems to streamline packaging and packing operations, and also improves efficiency in unpacking, reduces waste disposal, etc. Describe what you want to improve.

[Means for Solving the Problems] The present invention provides a package for cushioning and fixing, in which front and back members made of corrugated cardboard are handled to match the shape of the product to be packaged, and are bonded in a laminated manner with a mount as a core material. The present invention provides a method for laminated packaging of articles using partition plates.

That is, in the method of the present invention, as shown in FIG. 1(c), instead of molding the partition material, front and back members that match the shape of the packaged item are produced by punching out a cardboard material.
A rigid plate-shaped partition plate is used in which one or more of these are bonded to the top and bottom of a mount serving as a core material. Therefore, the recesses for cushioning and fixing the packaged items are present in the thickness direction of the partition plate, and the surface is flat without any unevenness.

[Effect]

The cardboard used as the front and back members of the partition plate used in the present invention can be single-sided, double-sided, double-sided, or double-sided, and the liner and medium paper are each JIS P2902.
, A class, B class, 0 as defined in JIS P3904
grade can be used. Further, as the mount serving as the core material, general paperboard for folding cartons, such as white paperboard, paperboard, and chipboard, can be used.

After punching the cardboard according to the product shape as mentioned above,
A sheet or a plurality of sheets are pasted together from above and below a mount using an adhesive to form a rigid planar plate. In some cases, the mount may also be molded to fit the shape of the product. However, for the partition plate for the bottom tier that touches the pallet, do not attach the corrugated cardboard to the bottom of the mount, and for the partition plate for the top tier, do not attach the corrugated cardboard to the bottom of the mount. Attach the pole directly to the plywood and do not use a backing paper.

As mentioned above, the packaging partition plate used in the laminated packaging of the present invention has a flat plate-like appearance because the recesses for cushioning and fixing the packaged items are formed toward the inside of the partition plate. ing. This planar shape makes it possible to arrange the items to be packaged and to simplify and simplify the partition material supply mechanism, which helps improve suitability for automation. A similar effect can be expected when removing the partition plate when unpacking.

Furthermore, when the partitioning material is composed only of paper materials such as corrugated poles and paperboard, the used bonds can be easily disposed of by incineration, and furthermore, they can be reused as waste paper as a raw material for paper pulp. In order to give the partition material even higher rigidity, it is also possible to use solid fiber bond as a mount, but in this case it cannot be reused as waste paper and must be incinerated.

Furthermore, the cost of the partitioning material can be reduced by freely selecting the quality and type of paper such as corrugated cardboard, paperboard, etc., which functions as a buffer and fixing material, depending on the item to be packaged.

〔Example〕

Examples will be described below with reference to figures.

FIGS. 2(a), 2(b), and 2(c) are schematic diagrams of the structure of partition plates for a unit load system used in the lowest stage, middle part, and top stage, respectively. In the figure, each plate is separated to make the configuration clear, but in reality, they are glued together.

The dimensions of the cardboard and mount are 1126s++X 102
0 m, the cardboard is provided with two types of shock-absorbing recesses in 6 rows x 5 columns and a diameter of 30 [Q] that are adapted to the top and bottom shapes of the packaged items. The center of each recess in the first row is 110M from the front edge of the cardboard, and the center of each of the four parts in the sixth row is 8M from the rear edge of the cardboard.
It is set at 5m. The bottom shelf partition plate (Figure 2 (a)) consists of three cardboard boxes and one mount, and is placed on the pallet.Then, fit the lower part of the item into each recess to separate the first part of the item. A layer is formed, and a partition plate for the middle section (Fig. 2 (b)) consisting of 3 sheets of waste cardboard, 1 sheet of backing paper, and 3 sheets of handling cardboard is placed on top of the layer, and the upper part of the item to be packaged is fitted into each recess. Com.

In the same manner, the second layer, third layer, etc. of the article are formed, and finally a top layer partition plate made of one plywood board and three pieces of cardboard is placed to cover each recess. Fit the top of the package. The thus-completed assembly is fixed by shrink-wrapping it with a plastic film using a known method, and finally it is covered with an outer box and tightened with a band.

〔Effect of the invention〕

According to the integrated packaging method of the present invention as described above, since the packaging can be carried out by the machine that is to be used for packaging, manual labor is not required and automation is possible, which contributes to streamlining packaging and packing operations and reducing costs. There is something big.
