Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended for packaging a cube-shaped packaged body, particularly a large number of plate-shaped packaged bodies, using an A-1 type packaging box. A preferred packaging device.

[Conventional technology]

As a packaging device for packaging a cube, the actual machine is Sho 61-117.
Japanese Patent No. 164 discloses a cushioning material 23 as shown in FIG. The cushioning material 23 has a plurality of parallel folding ruled lines a ', b', c'for folding the cushioning material 23 in a flat state in a deployed state and winding it around the cubical packaged article 21. .E'.f'.g'.h 'and holes 27 for inserting and engaging a part (corner) 21a of the packaged body 21 are formed.
When it is wrapped around the packaged body 21 as shown in FIG. 6 and then the packaged body 21 is put into the packaging box 22, a predetermined position in the packaged body 22 (see FIG. 7). It is designed to be buffered and fixed at the solid line position).

[Problems to be solved by the device]

However, when the cushioning material 23 as described above is used to buffer one packaged object 21 as shown in FIG. 6 and package it in the packaging box 22, the work is performed in the above order. Since it suffices to perform it, that is, since the cushioning material 23 is wrapped around the packaged object 21 outside the packaging box 22, and then the cushioning material 23 is put into the packaging box 22, there is no particular problem. With the cushioning material of No. 3, it is necessary to provide an appropriate space between the objects to be packaged, and to buffer and fix a plurality of objects to be packaged (for example, a plurality of plate-like objects) in one packaging box. When doing so, the following problems occur. That is, a. Outside the packaging box 22, the cushioning material 23 is freely bendable along a large number of folding ruled lines (a ′ to h ′). The plate-like packaged objects are kept in an upright state in which the packaged objects are provided in parallel with each other at appropriate intervals, and a part of each of the object to be packaged (corner or the like) is provided in the cushioning material 23 at appropriate intervals. It is very difficult to wind the cushioning material around all of the objects to be packaged by inserting the cushioning material into the holes formed in the required number.

b. In the packaging box 22, the cushioning material 23 is not only bendable along a large number of folding ruled lines (a ′ to h ′), but also the bending angle at each folding ruled line is very unstable. , Because it is difficult to identify this,
It is extremely difficult to put only such cushioning material 23 in the packaging box 22 and maintain its cross-sectional shape in the correct shape as shown by the solid line in FIG. 7. That is, the cross-sectional shape of the cushioning material 23 is likely to be a distorted shape as shown by a chain line in the figure.

Therefore, the packaging box 2 which is likely to be in such a distorted state
It is extremely difficult to insert the packaged body into the packaging box by inserting a predetermined portion of the packaged body (not shown) into the hole (not shown) of the cushioning material 23 in 2 later. .

There was such a problem.
