Description

Description: TECHNICAL FIELD The present invention relates to a method and a filling device for filling two different fillings with a partition film in a packaging bag that divides the inside into two parts by a partition film. Is.

[Prior Art] Conventionally, foods such as sprinkles have been sold in a packaging bag made of a transparent synthetic resin film. A desiccant, an antioxidant, an insect repellent, etc. (hereinafter referred to as a desiccant, etc.) were enclosed in each one. However, when vibration is applied, the desiccant floats on the upper surface, and in this state the appearance of the desiccant through the packaging bag is transparent and the appearance is not good, and the product value is reduced, and the desiccant etc. are filled. Since it comes into direct contact with existing food, there is a problem in that it is not good for hygiene.

Therefore, as a packaging bag that can solve such problems,
As described in Japanese Utility Model Application Laid-Open No. 61-30630, there is already known a structure in which the inside is divided into two on the front and back sides by one partitioning film and two accommodating portions are connected to each other. In this packaging bag, foods such as sprinkles and the like may be separated from the desiccant and the like, and the foods such as sprinkles may be packed in one of the compartments partitioned by a partition film, and the desiccant or the like may be stored in the other compartment. .

[Problems to be Solved by the Invention] However, since such a packaging bag is unstable because the partition film does not stop at a fixed position when the bag is opened,
With a conventional filling device that automatically fills a packaging bag having only one storage section, it is impossible to automatically fill foods such as sprinkles and desiccant into different storage sections.
This must be done manually, but this is problematic in terms of workability and productivity.

Therefore, an object of the present invention is to automatically move the partition film in the middle of filling different kinds of packings in the packaging bags having two kinds of storage portions, so that the filling of food, desiccant, etc. can be performed easily and easily. The object is to provide a method and an apparatus that enable speedy operation.

The interior of the packaging bag is divided into two by a partition film, and the packaging bag having two accommodating parts is vertically opened with the opening facing upward. Hold it, open the opening and blow air from diagonally upward toward the opening, push the partition film to one side and inflate the accommodation part, fill a predetermined amount of filling, and then approach the partition film of the opening. Air is blown from the upper side toward the same side of the opening, the partition film is pushed to the opposite side, and the other accommodation part is inflated to fill another filling material.

In addition, the second filling device divides the inside into two by a partition film and vertically holds the packaging bag having two accommodation parts with the opening facing upward, and continuously stops and transfers one step at a time in the horizontal plane. A support device is provided on the machine base, a second air blowing nozzle that positions the ejection port obliquely above the opening and faces the opening, and a supply hopper that positions the discharge port directly above the opening and fills the accommodation portion with filling material. And a third air blowing nozzle for directing the ejection port above the side of the opening closer to the partition film, and directing the third air blowing nozzle to the same side of the opening, one for each step of the supporting device. Consists of.

[Operation] A partitioning film divides the inside into two parts on the front and back sides, and holds the packaging bag having two accommodation parts vertically with the opening facing upward in the supporting device. Then, in this state, the packaging bag is transferred to the next step, air is blown from the second air blowing nozzle toward the opening, the partition film is pushed to one side, and the air is blown into the accommodation portion to inflate. Further, it is transferred to the next step, and a predetermined amount of filling material is filled from the supply hopper. Furthermore,
It is transferred to the next step, and air is blown toward the same side of the opening by the third air blowing nozzle from above the side of the opening of the packaging bag which is close to the partition film, and the partition film is pressed to the opposite side and the other side is accommodated. Blows air into the area to inflate. Then, the other filling is filled.
