A wicket post mounting in a bag stacking machine includes a base unit bolted to a conveyor plate. The base unit includes an upstanding wall with a plurality of machined, vertical post receptacles or openings. Each receptacle is identical to receive and physically support one post in precise accurate relation to a longitudinal location on the station plate of a second post. The spacing of the receptacles and posts is selected to receive bags with spaced holes. A releasable latch pin is secured to each receptacle. The pin projects into an appropriate opening in the post and locks the post in the receptacle. The base unit may include a pair of post mounting bases each having an offset edge wall abutting the station plate to accurately locate the base. Bolts pass through the mounting base into threaded holes in the station. Each base has two spaced receptacles, providing for post spacing of 4, 5 and 6 inches. The receptacles tilt the post slightly outwardly and each receptacle has a back slot of a circumferential width less than that of the post and each post has an aligned back recess. Alternately, a single base is slightly greater in length than maximum post spacing. A plurality of finished receptacles are in the one mounting wall.
A wicket indexed unit for sequentially aligning individual bag stacking units with a bag transfer unit for stacking plastic bags having spaced holes along a given edge portion of each bag, the plastic bags being formed with different hole-to-hole spacing, said bag stacking units each having spaced post aligned with said holes for retaining of the bags onto stacking units, said stacking units being secured to a conveyor, the improvement in said stacking units for mounting said spaced posts at each stacking unit, comprising a base unit having means for fixedly securing said stacking unit to said conveyor, said base unit being constructed with a plurality of longitudinally spaced post supports defining a plurality of different center-to-center locations to correspond to different spacing of the spaced holes in bags, each of said spaced post supports being an accurately finished support and said post supports being located on precise spaced centers of equal increments, a plurality of at least two stacking posts for each stacking unit, each of said posts having a mounting base portion complementing said post support for releasable attachment to said post supports for accurately locating said posts with precise center-to-center spacing corresponding to the holes in said plastic bags upon connection of said base portions to said post supports, and wherein said finished post supports constitute the sole means for precisely locating said posts on different center-to-center spacing.
A wicketing apparatus including an indexing conveyor and means to move said conveyor in predetermined equal steps for sequentially aligning stacking stations with a bag transfer unit for stacking bags having at least a pair of spaced holes and different bags having differently spaced holes with the spacing being in equal increments, comprising
A mounting apparatus for a wicket indexing unit including a plurality of like support structures longitudinally spaced and moveable into a bag receiving station for receiving a stack of bags, each bag having at least a pair of spaced holes, first bags having holes spaced a precise distance defining a minimum hole location and second bags having holes spaced a precise distance different than said first bag by a predetermined increment and defining an intermediate hole location and third bags having holes spaced a precise distance different than said second bag by a distance equal to the increment of change in distance between said first and second bags and defining a maximum hole location, the improvement in said mounting apparatus for mounting of wicket posts to said support structures for processing a stream of either said first, second or third bags,
