ABSTRACT:
Bag pick up and feed assembles pick up a flat folded bag from a magazine and direct the picked up bag to a bag positioner assembly, the feed assembly including a first set of rollers moved away from a second set before the bag is moved therebetween and thence together to feed the bag. The positioner assembly moves the bag to extend vertically for top edge portions being clampingly engaged by a carriage assembly and thereby forwardly conveyed to beneath a hopper spout. Bag top side wall portions of the clamped bags are spread by vacuum cups of the carriage assembly. Power operated linkage mechanism moves closed spout jaws downwardly between the spread side wall portions and thence open the jaws to spread the bag side walls as product is discharged through opening jaws to open the clamped bag. The carriage assembly includes clamp plates mounting bag top clamps, vacuum cup mounting members and mechanical linkage interconnecting the clamp plates and vacuum cup mounting members to move the clamp plates toward one another as the opening spout jaws force the cup mounting plates apart. A shaker subassembly mounts a saddle subassembly for vertical movement while the saddle subassembly includes a bag bottom support member that is reciprocate for shaking a bag during filling.
