Claims

[Scope of utility model registration request]

A large number of trays arranged at equal intervals within a tube-shaped film are transported together with the film in a vertical direction, and a cutting mechanism cuts the film between each tray, and the cutting mechanism cuts the film between each tray in the tray transport direction. In a tray packaging machine, the end of the cut film is suctioned and held in a first suction pipe installed on the front side, and the film end is bent onto the lower surface of the tray by the conveying force of the tray, above the first suction pipe. A fixed roll 16 and a movable roll 17 are arranged in parallel, and the shaft of the movable roll 17 is pivotally supported on a lever 26, and a third gear 33 provided on the support shaft 25 of the lever is connected to the shaft of the movable roll. Fixed 4th
While meshing with the gear 34, the first gear 31 fixed to the shaft of the fixed roll is connected to the idle second gear 3.
2a and 32b, the film folding device for a tray packaging machine is provided with an actuation mechanism that engages with the third gear 33 through gears 2a and 32b and operates the lever in accordance with the movement of the cutting mechanism.
