Abstract: A bag detection apparatus (50) for sensing the position and seam integrity of a deformable bag (24) and bag transfer apparatus (53) for gripping and maintaining positive control of the edges (25) of the bag (24) during transfer from a bag filling station to a bag closure station. The bag positioning and seam integrity detecting apparatus (50) includes pneumatic conduits (60-67) mounted on the bag distending assembly (23) of a bag filling apparatus (20) and coupled to pressure switches (68). A controller (101), monitoring increases in pressure at each pressure switch (68), determines the position and condition of the mounted bag (24). The transfer apparatus (52) includes a pair of elongated arms (80) having hook-shaped gripping fingers (82) formed to engage and cooperate with clamping members (83) to grip the bag proximate the upper edge (25). A bag detection method also is provided.

Abstract: An apparatus for mechanically bagging relatively fragile, leafy vegetables including a bag distending assembly, a sleeve-like inserter, a barrier movably mounted inside the inserter, and a drive assembly coupled to displace the inserter into the bag. The drive assembly includes two pneumatic cylinders so that the barrier can be controlled independently of the inserter and maintained in position inside the bag while the inserter is withdrawn. The inserter carries the leaves inside the bag without substantially compresssing or crushing and bruising the leaves, and the barrier permits inserter withdrawal without leaf damage. A process for inserting fragile leafy vegetables into a bag also is disclosed.
