Description
Rotating Arm wrapping machine
The rotating arm wrapping machine AV1620 and AV630 are designed for applications with high production rates. The rotating arm wrapping system and a stationary pallet allows the wrapping of unstable or light loads.
The variable arm rotation and film-carrier traverse speeds allow the amount of film overlap on the pack to be adjusted to suit the wrapping needs. The film-carrier incorporates a powered film pre-stretching unit.
The powered pre-stretching assembly on which the film reel is mounted stretches the film before it is applied to the pallet which takes advantages of the high elongation qualities of some stretch films. this system reduces the pressure on the edges of the light or delicate packs and considerably reduces film consumption. A sensing system detects the stretching ability of the film and automatically controls the amount of stretch being applied in accordance with the rectangular shape of the pallet load.
At the end of the wrapping cycle, the film is cut mechanically with a blade and the film end is held in a gripper ready for the start of the next cycle. a brush assembly presses the loose film end against the pallet and a hot pad unit moves forward to fix the film end to the wrapped pallet by welding. On irregular packs, a modified retractable arm carries the welding pad to the pallet and the welding is performed against a metal backing plate in cases where the film is not in direct contact with the pallet load surface.
The model AV 630 top sheet rotating arm machine, incorporates an automatic top-sheet film dispensing unit which applies a top sheet to the top of the pallet before wrapping, which covers five sides of the pallet load for greater protection. The top-sheet dispenser automatically detects the height of the pallets and can operate with a variety of pallet heights.
Applications: Bags, Cardboard, Construction, Paper, Plastic
