Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method and a filling device for filling two different fillings into a packaging bag whose interior is divided into front and back parts by a partition film, with a partition film separating the bag. It is.

[Prior art] Traditionally, foods such as furikake were packed and sold in packaging bags made of transparent synthetic resin film. Each package contained desiccant, antioxidant, insect repellent, etc. (hereinafter referred to as desiccant, etc.). However, when vibrations are applied, the desiccant floats to the top surface, and in this state, the desiccant etc. inside can be seen through the packaging bag, giving an unsightly appearance and lowering the product value. There was a problem in that it was not sanitary because it came into direct contact with food.

Therefore, as a packaging bag that can solve these problems, -
A structure in which the interior is divided into front and back halves by a sheet of partition film and has two accommodating portions that communicate with each other is already known as described in Japanese Utility Model Publication No. 61-30630. In this packaging bag, in order to separate food such as furikake and desiccant, etc., food such as furikake may be placed in one storage section separated by a partition film, and desiccant, etc. may be placed in the other storage section. .

[Problems to be Solved by the Invention] However, in such packaging bags, when the bag is opened, the partition film does not stay in a fixed position and is unstable. With conventional filling devices, it has been impossible to automatically fill food such as furikake and desiccant into separate storage sections. To force this process, it must be done manually, but this poses problems in terms of workability and productivity.

Therefore, an object of the present invention is to automatically move the partition film in the middle when filling a packaging bag with two storage sections with different fillings, thereby making it easier and easier to fill the packaging bag with food, desiccant, etc. The object of the present invention is to provide a method and a device that can be carried out quickly.

[Means for Solving the Problem] A method of filling the first packaging bag with stuffing is to divide the inside into two sides with a partition film and vertically hold the packaging bag with two storage parts with the opening facing upward. Hold the opening, open the opening, blow air toward the opening from diagonally above, push the partition film to one side and inflate the container, fill it with a predetermined amount of stuffing, and then close the partition film of the opening. Air is blown from above toward the same side of the opening to push the partition film to the opposite side and inflate the other container to fill it with another filling.

In addition, the second filling device divides the interior into two, front and back, using a partition film, holds the packaging bag vertically with the opening facing upward, and continuously stops and transfers the bag one step at a time in a horizontal plane. A support device is provided on the machine base, a second air blowing nozzle having a spout located diagonally above the opening and directed toward the opening, and a supply hopper having a discharge port located directly above the opening and filling the storage portion with stuffing. and a third air blowing nozzle whose jetting port is positioned above the side of the opening where the partition film is located and faces the same side of the opening, one for each step of the support device. It becomes more.

[Operation: A packaging bag whose interior is divided into two, front and back, with a partition film and which has two accommodating parts, is held vertically on a support device with the opening facing upward. Then, the packaging bag is transferred to the next step in this state, and air is blown toward the opening from the second air blowing nozzle to push the partition film to one side and blow air into the storage section to inflate it. Further, it is transferred to the next process and filled with a predetermined amount of filler from the supply hopper. Furthermore, the packaging bag is transferred to the next step, and a third air blowing nozzle blows air from above the opening of the packaging bag toward the same side of the opening to which the partitioning film is located, thereby pressing the partitioning film to the opposite side and pressing the partitioning film to the other side. Blow air into the housing to inflate it. Then fill with other fillings.
