Abstract
A bagging machine for automatically covering a loaded pallet with a bag formed from a tubing of resilient film. The tubing is fed by drive rollers down into the machine where vacuum heads grasp the sides of the tubing and spread it open. Fingers are then inserted and when an appropriate length of tubing is fed onto the fingers, a cut-and-seal mechanism cuts the tubing and seals the end of the bag. The fingers retract to further open and stretch the bag. The carriage in which the fingers are mounted is then lowered and the bag is fed onto the load.
Claims20
An improved bagging machine for covering a load with a bag formed from tubing of the type having
- means for feeding tubing to a work area for receiving the tubing,
- means for gripping the tubing, and spreading the tubing to an open position,
- fingers which are insertable into the tubing which has been spread open,
- means for severing the tubing and forming the bag therefrom, the bag being collected on the fingers,
- and means for providing relative vertical movement between the fingers and the load to cover the load with the bag collected on the fingers, wherein the improvement comprises:
- means for retracting the fingers simultaneously along mutually perpendicular horizontal components so that after the fingers have been inserted into the tubing, the tubing may be spread open outward to a position which will encompass the load.

- fingers which are insertable into the bag which has been spread open, and
- means for effecting relative vertical movement between the fingers and the load to cover the load with the bag collected on the fingers, wherein the improvement comprises:
- means for retracting the fingers outward along a first horizontal component;
- means for retracting the fingers outward along a second horizontal component, wherein the first and second horizontal components are mutually perpendicular, so that after the fingers have been inserted into the bag, the bag may be selectively spread open to a position which will encompass the load.
