A pattern former for assembling wrapped bakery products into predetermined patterns includes a vacuum turntable comprising a perforated plate which is driven by a belt extending around the periphery of the vacuum turntable and actuated by a motor. A first transfer apparatus includes a pusher plate which moves groups of wrapped bakery products onto the vacuum turntable and which retracts to facilitate the formation of a subsequent group of wrapped bakery products as a previous group is being transferred to the vacuum turntable. A second transfer apparatus includes a pusher plate which moves assembled patterns of wrapped bakery products from the vacuum turntable into bakery trays and which is retractable to facilitate the assembly of a subsequent pattern of wrapped bakery products as a previous pattern is being transferred to a bakery tray.

An in-line pattern forming apparatus includes a windowed endless roller conveyor disposed in a longitudinal system path for sequentially receiving sets of articles. A friction shoe shifts the set of articles through the conveyor window to an underlying turntable which is rotatable for selectively reorienting the set, whereupon the lead roller at the end of the window pushes the set off the turntable to a staging support which sequentially receives a plurality of sets to form a pattern. The pattern is then swept as a unit from the staging support to a container loader or other associated apparatus in the system path. Means may be provided for selectively shifting sets of articles on the staging support laterally of the path to facilitate formation of certain patterns.

A stacker/unstacker for receptacles such as bread pans or baskets or the like includes a pair of laterally spaced-apart endless chains having receptacle carriers mounted therebetween for conveying receptacles between an infeed-outfeed conveyor and the top of a receptacle stack. The conveyor chains are horizontally spaced-apart in a direction perpendicular to the lateral direction with the carriers mounted for rotation about two spaced-apart axes which are respectively fixed with respect to the chains so that the carriers are stably held in a predetermined orientation and undergo only translational movement along the conveyor path. The path has a transfer portion at the top of the stack wherein the carriers and carried receptacles remain stationary for a time during which the carriers are moved between support and release conditions to pick up or deposit receptacles at the top of the stack. Indexing mechanism moves the transfer portion vertically to keep it at the top of the stack as the stack height changes. Magnetic and non-magnetic carriers are disclosed, as well as several arrangements of the infeed-outfeed conveyor with respect to the stack, and an automatic storage system using the stacker/unstacker.

A system for loading groups of articles into containers includes an infeed conveyor which groups the articles into subgroups which are then selectively reoriented by a turntable-type orienting device. The oriented subgroups are then conveyed to a transfer area where they are accumulated into elements of a predetermined pattern of articles. A pusher sequentially pushes the pattern elements onto the lower reach of a window conveyor disposed at a loading station. A container conveyor runs beneath the window conveyor to deliver an empty container to the loading station, a lifter assembly then raising the empty container to a loading position immediately beneath the support reach. The window conveyor is then operated to drop the pattern of articles through the window thereof into the container. As the window conveyor continues its movement a pusher on the leading end of the conveyor section thereof pushes the loaded container onto a discharge slide assembly which then tilts downwardly to allow the filled container to the slide onto an outfeed conveyor which may convey loaded containers to downstream apparatus, such as a bottom-up stacking mechanism.

摘要:
An apparatus for accumulating into a group a series of spaced-apart loaves of bread in a bakery conveying line comprises an entry conveyor and an exit conveyor each including a driven belt of interconnected free rollers. Upon the arrival of the first loaf at the exit end of the exit conveyor, the exit conveyor is stopped, with succeeding loaves accumulating behind the first loaf under the continued action of the entry conveyor to form a contiguous group which fills first the exit conveyor and then successive zones of the entry conveyor. As each zone is filled, a corresponding shoe is moved into engagement with the rollers passing through that zone for rotating them to counteract the movement of the entry conveyor belt and relieve pressure on the accumulated loaves. When downstream equipment calls for more loaves, the exit conveyor is restarted and the shoes are removed from the rollers in all but the last zone, and simultaneously another shoe momentarily engages those rollers to stop the counter-rotation thereof and the accumulated group is conveyed from the accumulator. Subsequently the shoe in the last zone is disengaged to restart the cycle.
