Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic packaging device for frozen confectionery, and more specifically, after the frozen confectionery is put into a packaging bag, the opening is sealed and the device is automatically placed on a product conveying device. This invention relates to an automatic packaging device for frozen confectionery.

Conventional bags for packaging stick-shaped frozen sweets are made by folding thin sheets of paper into a gusset, then partially overlapping two opposing sides and one of the other two opposing sides, and applying adhesive or the paper. It was formed by heat-pressing a synthetic resin film that was coated on one side of the leaf.

However, when such a conventional bag is folded into a gusset, the width of the fold is the same, so the folded bag is automatically removed from the supply cartridge using the ejecting claw and inserted into the bag from the ejecting opening. When blowing air into the folded bag to inflate it, it is difficult to attach the ejecting claw to the folded part, so automatic feeding using a feeding cartridge is difficult.
Depending on the folding condition and amount of the bag inside the IJ, it is not reliable, and the bag must be removed manually.

This invention improves the bag for packaging frozen confectionery so that the product can be packed into the bag and the opening of the bag can be purposefully sealed, thereby overcoming the drawbacks of the conventional bag. This includes a product take-out means that automatically takes out delivered products one by one, carries them at a predetermined position 1, and drops them, and a gusset-folded packaging bag having a rear part wider than the front part. a packaging bag storage case containing a large number of the packaging bags with their narrow front faces facing the delivery direction; means for locking the wide rear parts of the packaging bags at the case packaging bag delivery port; means for inflating the folded bag by autonomously sending out an air flow to the opening of the foremost zero-packed bag that is locked by the locking means; It consists of a means for autonomously sealing the opening of the packaged packaging bag, a means for autonomously discharging the packaged product onto a conveying means, and a driving means for autonomously operating each of the above-mentioned parts. The present invention provides a packaging device for frozen confectionery.

The packaging device of the present invention will be described in detail below.

FIGS. 1 to 3 show the structure of a current bag body that has been improved in putting the loading device of the present invention into practical use.

Figure 1 is an exploded view of the packaging bag.The bag material is made of a synthetic resin, such as a polyolefin resin film, that does not become brittle at low temperatures on both sides of the paper sheet, or one side of the synthetic resin film. Current bag material 1 coated with metal such as aluminum
Cut into a roughly square shape and make two folds parallel to two opposite sides of one side.
Joining part 3a and s3b to make the single leaf bag material into a cylinder shape with a and 2b, and join the front parts 5a and 5b on the left and right of the crease 4 where the current bag material of the old octopus was folded in half. The rear parts 6a and 6b which are wider than the front part are in contact with the front part, and the fold 7a p1b~ is made between the front part and the rear part (7)M.
9a and 9b are provided and the folding portions 10a and 1 are narrow on the front side.

1b as shown in FIG.
After folding into a V-shape between g and 6b, the joint part 12 is sealed by applying an adhesive or applying a coated synthetic resin film and applying heat and pressure. The bag body 14 is completed.

As shown in FIG.
The total width length t2 of the rear surface portions 6a and 6b is compared to the total width length t1 of b.
Since the length is long, as will be described later, when taking out the bag from the bag storage case and inserting the stick-shaped frozen sweets from the opening 13, air is blown into the folded bag. When the guide rail-m of the cartridge is housed in the folded fold part so as to hold the rear parts 6a and 6b,
The bag itself can be inflated by hooking a claw to open the opening 13 of the folded packaging bag 14 on the front part 5ay sb and pulling it toward you. The packaging bag 14 is constructed so that when air is blown into the bag 13, the packaging bag 14 can be expanded into a casing so that there is no problem in inserting the frozen confectionery.
