The stacking rib is configured so that when stacked, it is placed on the flange of the lower tray and a stacking rib is formed to project outward so that a constant gap is formed between the upper and lower flanges. Four screws are arranged at the four corners of the bent tray provided above, where the flanges of the bottom tray are placed. When the screw is rotated, the flange of the bottom tray meshes with it depending on the direction of rotation, and a screw groove is engraved to move this tray downward and separate it.The above four screws are separated in the tray separation direction. It is configured to include a rotation drive mechanism for rotating.

[0007]

According to the above-mentioned structure, a continuous food / drink continuous package which is transferred while being vacuum-adsorbed by, for example, an intermittent feed drum as the intermittent feed means is separated one by one by the cutter means, and the film-packaged food / beverage tools are separated. It is said that

Adhesive glue is transferred to the film surface of the film-packed food and drink by the adhesive transfer means by the adhesive transfer means. The film-packaged food and drink to which the glue has been transferred is transferred from the drum surface, which is vacuum-adsorbed, to the lunch tray on the conveyor by the food and drink applicator, and is pasted.

Further, in the tray feeding means, when the four screws are rotated by the rotation driving mechanism, the flanges of the lowermost tray are engaged with the screw grooves and are transferred downward, so that the trays stacked up to the highest position. The lower trays can be sequentially separated and fed to the conveyor means.
