BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow wrapping method and a pillow wrapping machine for wrapping a package by applying a vertical seal and a horizontal seal to a cylindrical packaging film on which the package is placed.

[0002]

2. Description of the Related Art Conventionally, as one of packages, in addition to a package to be originally packed, an accessory related to the package is enclosed in the same bag. For example, in a package in which food is packaged, a freshness maintaining agent for maintaining the freshness of the food is enclosed in the package. As an example of the freshness preserving agent, there is a deoxidizing agent that absorbs oxygen contained in the air inside the bag to create an anoxic state inside the packaging bag, thereby preventing quality deterioration due to food oxidation. In addition to oxygen scavengers,
Examples of the freshness maintaining agent include a moisture absorbent that absorbs moisture, a deodorant that absorbs odor, and a preservative that volatilizes alcohol components. In addition, when packaging food, other accessories other than the freshness preservative include soy sauce, sauces, hot peppers, chili oil, sachets containing seasonings and spices, and small printed materials that explain the contents of the package. is there.

[0003] When the package is a food, the freshness-maintaining agent may be mistaken for an ingredient, seasoning or spice added to the food, and may be directly eaten or processed or cooked together with the food. And may inadvertently eat. In order to eliminate the possibility of such accidental eating, when packaging is packaged in a bag formed from a packaging film, an accessory is attached to the inner surface of the packaging film, for example, using a double-sided tape. . For example, Japanese Patent Application Laid-Open Nos. 1-1111606 and 1-113930 relate to bag making and filling of food.
There is one disclosed in Japanese Patent Publication No. 3 (JP-A) No. 3 (1999). In this publication, a plurality of attached bags are automatically fed out one by one, and a double-sided adhesive tape, an adhesive or an adhesive is applied to one side of the pulled out attached bags. An adhesive layer or a pressure-sensitive adhesive layer is formed on the inner surface of the bag other than the bag seal portion corresponding to one bag of the heat-adhesive sheet-like packaging material transferred to the bag-making and filling means. The layered attachment bag is automatically attached via the adhesive layer or the pressure-sensitive adhesive layer to form a sheet packaging material with the attachment bag, and the sheet packaging material with the attachment bag is positioned inside the attachment bag. Automatic bag making so that
Food is filled in the bag made, sealed, and packed. Even if the food inside is taken out of the packaging bag, the additional bag remains inside the packaging bag, thereby preventing the inedible drug from being accidentally eaten. This publication discloses a regular pillow packaging machine as a bag making and filling machine.

Further, before the band-shaped packaging film unwound from the raw film roll is hung on a former, it is adhered by a suitable method to a position near the edge of the packaging film and at a position other than the position where the horizontal sealing is performed. Japanese Patent Publication No. 7-110649 discloses a vertical bag-making filling and packaging method in which a small bag is inserted into a product dropping cylinder through a small bag inlet. Since the small bag is sealed in the vertical seal portion and accommodated in the bonded state on the rear surface of the bag, the small bag remains in the packaging bag even when the bag is opened, and there is no danger of mixing into food or accidental eating. Also, when trying to view the package inside the bag from the transparent portion on the front of the bag, the small bag does not become an obstacle and the package can be seen with the eyes.

Since the present invention is configured as described above, it has the following effects. That is, according to the pillow packaging method and the pillow packaging machine of the present invention, even in a small-scale production in which packages and accessories are manually supplied,
Even when the package and the accessory are automatically supplied, the package and the accessory are supplied to the packaging position in a state where the package and the accessory are stacked.
The accessory of the package can be supplied to the package accurately and reliably at low cost. Even if the width of the packaging film or the ratio of the width of the accessory to the width of the package is relatively large, the accessory can be properly attached to the inside of the packaging film constituting the package. Since the accessory is not attached to the packaging film before being formed by the former, the accessory does not peel off from the packaging film when passing through the former. In addition, since the position of the accessory with respect to the package is predetermined at a position overlapping the package, there is no variation in the attachment position when the package is formed. As a result, the attachment position of the attachment to the packaging film is stabilized, so that even if the attachment has a hard edge, the attachment is enclosed in a predetermined position inside the package and the attachment is attached. The displacement does not damage the packaging film or impair the sealing performance of the bag package. Further, by attaching the accessory to the side of the package where the back-sticking seal portion is formed, the accessory can be securely attached on the back side of the package. The packaging film is often printed on the design, product name, product content, etc.
It is also commonly employed to make a portion of the packaging film transparent so that the package inside can be identified through the packaging film. Since the accessory is not attached to the front side of the bag package, even when the bag package is displayed as a commodity at a store, the consumer does not see the package because of the accessory.
