Description

Flattening device for bag packaging products {FLATTENING DEVICE FOR BAGGED PACKAGING PRODUCTS}

The present invention relates to a flattening device for bag packaging products that flattens the surface of the bag packaging product during the conveyor transfer process so that the surface of the bag packaging product becomes flat. More specifically, the present invention relates to a device for flattening the bag packaging product so that the surface of the bag packaging product becomes flat during the transfer process of the conveyor. It relates to a flattening device for bag packaging products that can gradually flatten the surface of the bag packaging product by applying an external force to the surface of the bag packaging product during the process of transporting the bag packaging product through a conveyor to alleviate the problem.

In general, an airtight plastic packaging bag is a bag in which a space is formed inside by heat-sealing the edges of two or three sheets of various known vinyl compounds such as PP (polypropylene) and PE (polyethylene).

These sealed plastic packaging bags are divided into various types such as pouches and self-standing sealed plastic packaging bags, depending on their use, and are used to package liquid or gel-type fillers such as beverages, detergents, fabric softeners, soybean paste, and red pepper paste in the inner space. Used for storage.

In addition, sealed plastic packaging bags are easy to carry and have low packaging costs, so they are used as refillable containers, replacing glass bottles, cans, and plastic containers. In particular, airtight plastic packaging bags are used as packaging materials for frozen food such as dumplings.

However, when packaging frozen food in an airtight plastic bag, the frozen food is not placed evenly inside the airtight plastic bag during the process of being put into the airtight plastic bag, and the frozen food is lumped in some spaces. Problems with maintaining may arise.

In addition, if the bag packaging product, which consists of frozen food packaged in an airtight plastic packaging bag, has a bumpy appearance due to the frozen food clumped together, the process of flattening the bag packaging product in order to pack the bag packaging product by laminating it inside the box is necessary. It becomes necessary.

Figure 1 is a schematic diagram schematically showing a conventional automatic packaging system.

Referring to Figure 1, the conventional automatic packaging system includes a flattening part 10 that flattens the bag packaging products, a gap adjustment part 20 that adjusts the gap between the bag packaging products, and a stacking of the bag packaging products in two or three pieces. Includes a laminated part (30).

The spacing adjusting part 20 consists of a primary spacing adjusting part (20A), a secondary spacing adjusting part (20B), and a connection part (20C), and is adjusted to an appropriate distance through the primary and secondary spacing adjusting parts (20A, 20B). Bag-packaged products with adjusted intervals are transferred to the laminated part 30 through the conveyor belt 23 that constitutes the connection portion 20C.

In this way, the laminated bag packaging products (P1, P2) must be kept in a stable laminated state without being disturbed until they are placed inside the box. However, if a bend is formed in the bag packaging product, the raised product (P1) will slip and not be stable. Due to deviation from the position, problems may occur where the alignment of the laminated products becomes worse even before box packaging.

Since this misalignment leads to poor box packaging, there is a problem that it inevitably becomes a factor that greatly deteriorates the automation efficiency of box packaging.

Republic of Korea Patent No. 10-2499404 (announced on February 10, 2023) Republic of Korea Patent No. 10-2127496 (announced on June 26, 2020) Republic of Korea Patent Publication No. 10-2022-0129232 (published on September 23, 2022) Republic of Korea Patent No. 10-1224846 (announced on February 5, 2013)
