Abstract
A continuous motion in line sealer assembly includes a sealer star wheel which is coordinated with a plurality of rotatable and receiprocable vacuum heads. Each vacuum head obtains a flexible foil sealing disk from a point of supply and positions the disk atop a container. The vacuum head and container then pass through an induction tunnel to activate a heatable adhesive. A pair of stationary cam plates control both the reciprocal motion of the vacuum head as well as providing it with a dwell time which momentarily interrupts its continuous motion to facilitate sealing disk acquisition.
Claims20
A continuous motion, in-line sealer assembly useable to apply a flexible foil sealing disk to the mouth of a container, said sealer assembly comprising:
- an infeed means for continuously supplying containers to be sealed;
- a continuously rotatable sealer star wheel having a plurality of sealer star wheel pockets, each said sealer star wheel pocket being sized to receive a container from said infeed means;
- a reciprocable vacuum head positioned above each said sealer star wheel pocket;
- means to vertically reciprocate each said vacuum head;
- means to rotate each said vacuum head in coordination with a cooperating one of said sealer star wheel pockets;
- supply means for supplying said flexible foil sealing disks to a supply point;
- dwell means for causing each said vacuum head to dwell mometarily at said supply point;
- means for activating an adhesive layer of said sealing disk when said disk has been brought into contact with a container to be sealed;
- and
- outfeed means for transferring sealed containers away from said sealer assembly.
