Description

The present invention relates to a two-chamber packaging bag supply device that supplies a two-chamber packaging bag in which a bag is divided into two compartments by a divided sheet to a bag supply packaging device.

2. Description of the Related Art Conventionally, a two-chamber packaging bag in which the inside of a general synthetic resin packaging bag is partitioned by a divided sheet is known. That is, it is a packaging bag for packaging food and two types of articles to be packaged, such as an oxygen scavenger and a desiccant, together. The purpose of the two-compartment packaging bag is to avoid direct contact between food and articles other than food, and to prevent accidental ingestion and accidental eating when both are mixed at the time of opening.

In the case where the packing material is filled into the two-chamber packaging bag by the filling device, it is necessary to surely fill each chamber in the bag divided into two chambers by the divided sheet. In particular, when the packaged product is a packaged product other than food, such as a food and an oxygen scavenger, prevention of erroneous filling thereof may be strictly required. However, since such a packaging bag is made of a soft thin sheet made of a synthetic resin, it may be difficult to expect certainty in the opening of the bag mouths of the two chambers when the object to be packaged is filled. .

In order to solve such a problem, various methods have been conventionally considered. For example, a suction port is opened in the bag mouth, and the bag mouth is selectively opened by selectively sucking the divided sheet from the suction port (Patent Document 1), or a suction force from the suction port provided in the bag mouth. The opening of the bag is selectively opened by providing a difference in the strength of the bag (Patent Document 2). Also, a suction port is provided in one sheet of the bag mouth, the divided sheet is suctioned from this suction port, one chamber is opened, the object to be packaged is filled and spot sealed, and then the other chamber is opened. It has also been proposed to eliminate erroneous filling by filling an article to be packaged (Patent Documents 3 and 4).

However, the techniques described in the above prior art documents have the following problems. That is,
(1) Since the opening of each chamber of the packaging bag partitioned by the split sheet of the two-chamber packaging bag is on the same end side of the bag, by mistakenly opening each chamber partitioned by the split sheet, for example, In addition, there is a problem that there is a possibility that erroneous filling of the food as the first package and the small bag of the oxygen scavenger as the second package may occur.
(2) In the case of automatically filling a two-chamber packaging bag with an object to be packaged by, for example, a rotary bag supply packaging machine, the opening of the bag mouth, the filling of the object to be packed, and the sealing of the bag mouth are continuously performed. Since it is necessary to repeat the process, the probability of occurrence of a packaging error increases.
(3) The conventional two-chamber packaging bag has a problem that the appearance of the packaging bag is poor because the suction port must be formed on the front and back surfaces or any one of the sheet surfaces of the sheet at the bag opening.
