DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method and an apparatus for packaging an object to be packaged in a pillow packaging bag having shape retention.

[0002]

2. Description of the Related Art A method for improving the commercial value of a packaged item contained in a pillow packaging bag and protecting the packaged item.
As one means, it has been conventionally known that an article to be packaged is placed on a tray made of a material such as cardboard, plastic, or styrene foam, and then pillow-packed with a horizontal bag making and filling machine. That is, the packaging bag is given a shape-retaining property by the tray to improve and protect the commercial value of the article to be packaged.

[0003]

In the case of using the tray to pack an article to be packaged by a horizontal bag making / filling / packaging machine, the tray is supplied on a supply means for the article to be packaged which is connected to the packaging machine. A separate tray supply device, an alignment supply device for placing the articles to be packaged on the tray in a state of being arranged, and the like are required separately, and there has been a problem that the equipment cost increases. Also, when using a tray, the material cost of the tray itself is added to the manufacturing cost (packing cost) of the product as compared with the packaging of only the packaging material, so the selling price of the product increases and the burden on consumers increases A flaw is pointed out. Furthermore, in view of environmental problems such as garbage disposal, the drawback of excessive packaging using a tray has been pointed out, and there is a need for a packaging form that can maintain shape and improve commercial value without using a tray.

[Modification] In the first embodiment, the release paper 54 and the label 22 fed from one supply roll 55 are replaced by two.
Although the configuration of cutting into two pieces has been described, the present invention is not limited to this. For example, two supply rolls 5 in advance
5, 55 are provided, and the labels 22 attached to the release paper 54 fed from the respective supply rolls 55 are separately adhered between the pair of lines 53, 53 of the strip film 24. You may. Also in the second embodiment, two supply rolls 64, 64 are provided and each supply roll 6 is provided.
The band-shaped label 63 fed out from 4 is cut into predetermined dimensions,
The cut labels 22 can be separately heat-sealed between the pair of lines 53 of the strip film 24. Further, in the third embodiment, the release paper and the label fed from one supply roll are cut into two,
The configuration may be such that each release paper is guided to the corresponding location and the label is attached to the tubular film.

The width of the label 22 is determined by
If it is not larger than the interval of 53, it may be slightly shorter than the interval. It is preferable that the length of the label 22 is such that the ends do not intervene in the gusset folds 30a, 30a. The dimension may exist in the portion 30a.

Further, the constitutions of the label supply and sticking means, the label sealing means, the streaking means, the horizontal bag making and filling machine, the vertical bag making and filling machine and the like are not limited to those of the embodiment. Other known configurations and methods can be appropriately adopted.

[0046]

As described above, according to the packaging method and apparatus according to the present invention, the packaging bag can be kept in the shape of a rectangular tube without using a tray. Thus, a packaging bag capable of effectively protecting the packaged object is obtained. Further, since a tray supply device and a device for arranging and supplying articles to be packaged are not required, equipment costs can be reduced and packaging costs can be reduced. Furthermore, since the packaging form does not use a tray, there is an advantage that a packaging bag suitable for environmental problems such as garbage disposal can be provided.
