  By the way, in recent years, for example, home appliances such as indoor units of air conditioners are produced at a first base where the main part of the unit is inexpensive in terms of materials and processing costs, and the semi-finished products thus produced are supplied to the second base. It is increasingly transported, assembled at a second location, and shipped as a finished product. At this time, the semi-finished products are collected and packaged at the first base and transported, and the finished products are shipped from the second base by individual packaging.

  FIG. 4 is a perspective view showing a corrugated cardboard side pad that holds both ends of an object to be packed in collective packaging, and FIG. 5 is an explanatory view of the collective packaging method. As shown in FIGS. 4 and 5, in the transport mode of the semi-finished product A, the left and right ends of the main body of the semi-finished product A are stacked on the paper pallet 100 in a state where they are held by the buffer side pads 101. The collected package is wound around the stretch film 103 to form a collective package. In this case, stretch packaging is performed in a state where the four corners of the packaged object are reinforced by the L-shaped reinforcement angles 104 so that the stacked packaged articles (semi-finished products) A are not displaced.

  However, the cushioning side pad 101 used in such a semi-finished product transportation system is either disposable or collected and reused as a cushioning material for collective packaging. The emergence of usage systems is desired.

In view of the above, an object of the present invention is to provide a packing material such as a side pad that can be effectively used for collective packaging and individual packaging .

In order to achieve the above-described object, the present invention provides a method for stacking packages to be packaged in which both left and right ends are held by the packaging material on a pallet and unitized as one large cargo. It can be used as a packaging material that holds both left and right ends, and it can also be used as an interior cushioning material that is housed in an individual packaging case and holds both left and right ends of the packaged item. is formed in a rectangular solid shape suitable for instrumentation, a packing material holding recess left and right ends can be fitted and held to the left and right ends appearance object to be packed in accordance with the shape of the object to be packed has been recessed in the inner surface, set In order to prevent the displacement of the packaging material when packaging, a convex portion for preventing the deviation is formed on the top surface, and a concave portion is formed on the bottom surface corresponding to the convex portion, and when the objects to be packed are collectively packaged The protrusion and the recess of the upper packing material Fasten deviation is performed, also in a state of accommodating the packaging material into individual packaging case when the individual packaging, both protrusions of the packaging material facing each other in the lateral direction is fitted and held to the left and right ends of the object to be packed can accommodate accessories case during, and as accessories case can secure a positionable intervals in the left-right direction, at the same intervals as the length in the horizontal direction of the accessory case, the projection forming position is set It is characterized by that.

  According to the said structure, since the packaging material for buffer for collective packaging can be reused as it is as an interior cushioning material for individual packaging, the packaging material can be used effectively.

  Here, collective packaging is a packaging method that makes it easy to handle and transport a plurality of items to be packaged into a single large cargo, which can be handled and transported by a machine. Hold fixed. Further, individual packaging means that the items to be packed are not packaged together but packaged individually.

  In such a packing material, a convex portion for preventing slippage is formed on the top surface, a concave portion is formed on the bottom surface of the packing material, and the convex portion and the concave portion of the upper packing material are formed when collectively packaging the items to be packed. Can be engaged with each other to prevent slippage. With a simple structure such as a concave / convex portion for preventing slippage, it is possible to easily prevent slippage at the time of collective wrapping, and the reinforcement angles used for the four corner portions at the time of collective wrapping become unnecessary.

  The packaged items at this time can be finished products in both collective packaging and individual packaging, but the packaged items to be packaged together are semi-finished products, and the packaged items individually packaged are the finished products. can do.

  With this configuration, even if the production area (first base) of the main part (semi-finished product) of the packaged goods and the assembly place (second base) as a finished product are in different regions, The packing material at the time of collective packaging of the finished product and the cushioning material at the time of individual packaging of the finished product can be made the same member, and the material cost can be reduced.

  In addition, the convex portions of the packing material at both ends of the packaged item are arranged so that the accessory case can be accommodated between the opposing convex portions, and an interval in which the accessory case can be positioned can be secured. A convex portion forming position can be set.

  According to the said structure, an accessory case can be mounted on it using the convex part of the top | upper surface of a packing material, and it can position so that an accessory case may not move. Therefore, it is not necessary to set the size of the accessory case to be the same as the size of the inner surface of the individual packaging case, and the accessory case can be reduced in size.

  In addition, the indoor unit of an air conditioner can be illustrated as a to-be-packaged item. This type of indoor unit is particularly effective because its main parts are produced overseas and are often subjected to final assembly, electrical inspection, etc. after transportation to the country. In addition, the accessory case includes, for example, an installation plate, a remote controller, a construction-related part, an instruction manual, and the like when the object to be packed is an indoor unit of an air conditioner. Furthermore, the material of the packing material may be either foamed resin or paper made of cardboard or the like.

In addition, the packing material is not limited to the both ends in the front-rear direction and the left-right direction as long as it holds both ends of the object to be packed. If this is applied, it effectively acts as a stopper for shifting the object to be packed or for positioning the accessory case.

  As described above, according to the present invention, in the packing device that collects and packs the packed objects that are held by the packing material at both ends on the pallet, when individually packing the packed objects in the individual packaging case, Since the packaging material is accommodated in the individual packaging case and reused as a cushioning material for the interior that holds both ends of the packaged item, the material cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a side pad used in a packaging device according to an embodiment of the present invention, FIG. 2 is an explanatory diagram of a collective packaging method, and FIG. 3 is an explanatory diagram when individually packaging indoor units of an air conditioner. .
