Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging device that can fill and package items in three formats: a tray case, a wrap-around case, and a set-up case using a single packaging machine.

Packaging not only protects the contents, but also must be able to be displayed at stores and lead to promotions. Therefore, we use three types of packaging depending on the product: tray case, wrap-round case, and set-up case. form is used.

The shape of the tray case and the wrap-round case before packaging is a flat flag, whereas the shape of the packaging mJ of the set-up case is glued in a river direction shape.
In addition, since it is folded flat, the packaging procedure is different, and conventionally one packaging machine could not package three different shapes.

For this reason, the packaging machines for tray cases and wrap-round cases and the packaging machines for set-up cases are separate, and it is necessary to use different machines depending on the items to be packaged.

This invention solves the above-mentioned drawbacks by making it possible to perform three types of packaging, such as a tray case, a wrap-around case, and a set-up case, with one packaging machine. The purpose is to reduce line space.

This invention works to raise the side wall of the packaging material in the endless running body at the same pitch as the intermittent running pitch, and also stops the running body at the tail of the running body using a shape-retaining member gold film that prevents the side wall from collapsing. Supplying the packaging material taken out from the magazine to the shape-retaining member, and shaping it into a state into which an item can be inserted,
And between the reeds that reach the head of the running body, are the items from the side? Insert the inner flap into that area using the folding device, then fold the outer flap using the λth folding device and glue the overlapping surfaces. To provide a packaging device for folding W and adhering adhesive.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
