Description

{AUTOMATIC ZIPPER BAG FOLDING APPARATUS}

This invention relates to an automatic zipper bag folding device, and more particularly, to an automatic zipper bag folding device which enables easy packaging work by stacking multiple zipper bags supplied in an unfolded state from a zipper bag supply section, and then folding the middle of the multiple stacked zipper bags and stacking them in a stacking basket.

Generally, vinyl bags are made of synthetic resins such as polyvinyl chloride and polyethylene through inflation extrusion, and are equipped with cut lines and heat-sealed sections so that items can be stored inside.

In food stores such as large discount stores and department stores where plastic bags are used in large quantities, roll bags with plastic bags are mainly used. These are made by forming multiple fused sections for sealing and easy-to-cut sections at regular intervals along the length, and then wrapping them in film form.

Meanwhile, disposable plastic bags other than rollbacks are packaged in a form in which multiple plastic bags are folded to be stacked and placed in a paper box or pack so that they can be used one by one.

In the case of vinyl bags that are laminated in this way, the lamination process is done automatically rather than manually, but the alignment of the vinyl bags in each layer is not consistent during the lamination process, making automatic packaging difficult. In addition, when the vinyl bags are packaged and used, there is a problem in that it is difficult to easily take out vinyl bags that are not aligned.

In addition, since the process of stacking and then removing the products is not sequential, the stacking state becomes disordered, making packaging difficult.

And even if the plastic bags are folded during the lamination process, there is a problem in that the plastic bags that were laminated become disordered due to the surrounding air caused by the movement of various devices.

With such prior art, a folding and laminating method and device for a continuously formed vinyl bag were proposed in Patent Publication No. 10-0605477 (July 20, 2006), and the proposed folding and laminating method and device were packaged so that the continuously formed vinyl bags could be pulled out one by one from inside a packaging box and used like tissues that are pulled out one by one. However, there was a problem that it was difficult to apply in the case of a zipper bag composed of discontinuous individual sheets, and there was a cumbersome problem in the process of folding the middle of a zipper bag laminated with multiple sheets.

Meanwhile, another conventional technology, a vinyl bag folding and stacking device, as designated by Patent Publication No. 10-0937893 (January 13, 2010), has been proposed. The proposed folding and stacking device sequentially folds vinyl bags having a heat-sealing section and a cutting section formed therein and stacks them on a stacking conveyor, and when a certain amount of vinyl bags are stacked on the stacking conveyor, the stacked vinyl bags are discharged by being loaded onto a discharge conveyor through a take-out pressure section. However, this device also had difficulty in folding and stacking zipper bags.
