Abstract: 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.

Abstract: A pattern former for assembling wrapped bakery products into predetermined patterns comprises a perforated vacuum turntable. Vacuum is applied to the vacuum turntable while bakery products are loaded thereon and positioned in a predetermined pattern. Once the bakery products are positioned on the turntable in the predetermined pattern, an air assist is applied to the vacuum turntable while the bakery products are unloaded therefrom. The air assist eliminates contact between the wrappers of the wrapped bakery product and the upper surface of the turntable thereby eliminating disorientation of the bakery products within the wrappers.

Abstract: A pattern former for assembling wrapped bakery products into predetermined patterns includes a vacuum turntable. A first transfer apparatus moves groups of wrapped bakery products onto the vacuum turntable and a second transfer apparatus moves assembled patterns of wrapped bakery products from the vacuum turntable into bakery trays. A bakery tray loading system receives unfilled bakery trays and sequentially delivers unfilled bakery trays to a bakery tray loading station adjacent to the vacuum turntable. A conveyor assembly within the bakery tray loading station supports the bakery tray while being filled and thereafter conveys the loaded bakery tray onto an out-feed conveyor for further processing.

Abstract: A conveyor system for use in a continuous proofing and baking apparatus. The system has a conveyor chain, having a plurality of links, which moves along a track. Each link supports a product supporting grid, which has four circular rings. Pole pieces are located in at least some of the rings. Each pole piece has a conical section and can move horizontally relative to the grid. A magnet in each pole piece attaches the pole piece to a product pan.

Abstract: An apparatus for continuous bakery products includes a carriage having opposed sealing jaws. Upper and lower webs of wrapping material extend between the jaws of the carriage along a bakery product path. Bakery products to be wrapped are advanced along the bakery product path between the webs of wrapping material and between the initially open jaws of the carriage. The jaws of the carriage are then closed to form transverse seals at the trailing edge of a leading package of bakery products and at the leading edge of a trailing package of bakery products. The carriage is advanced along the bakery product path during the sealing operation so that sealing of the bakery product packages is carried out on a continuous basis.

Abstract: In an automated commercial baking system, a bakery utensil storage system is provided for automatically receiving baking utensils from a continuous conveyor of the baking system and immediately directing the utensils over a selectively positionable curved conveyor for engagement with a predetermined one of a series of table top conveyors from where they are immediately returned to the baking system or lifted by and stored in elevators associated with the table top conveyors. When needed, the utensils are lowered by the elevators for engagement with the table top conveyors from where they are carried to a selectively positionable curved conveyor for return to the continuous conveyor of the baking system.

Abstract: An article sorting switch comprising a plurality of pallet support members and means for moving pallet support members through a predetermined closed course. Pallets are slideably supported on the pallet support members in abutting relationship and have switch engaging members depending therefrom. The pallets have lower arcuate side portions that allow the pallets to remain in continuous sequential contact as the pallets pass through arcuate portions of the closed course. A switching mechanism is provided for selectively directing the pallets to one of several diverging article conveying paths. The article conveying paths are defined by sorting guide members, and return guide members are provided for realigning the pallets to a central location corresponding to the switching mechanism. Knife edge conveyors are provided to load and unload the article sorting switch without subjecting the articles to any substantial vertical drop.

Abstract: An oven (20) includes an oven enclosure (24) having a conveyor (40) mounted therein for transporting food products through the oven. A plurality of ribbon burners (100) are mounted within the oven interior (32) adjacent the path of the conveyor to heat the interior of the oven. Heated gases generated by operation of the ribbon burners are received through inlet plenums (140) under operation of a circulation fan (146) and are discharged through discharge tubes (154) extending adjacent portions of the conveyor (40) remote from the locations of the ribbon burners (100). Exhaust gases are removed from the oven interior through discharge ports (180) by exhaust blower assemblies (184) which are operated to remove exhaust gases from the oven interior at a rate proportional to the flow rate of combustion air and gaseous fuel into the ribbon burners.

Abstract: A conveyor system (28-30) includes a track (110) and a conveyor chain (70) for movement along the track. The conveyor chain comprises a plurality of identical links (72) each including a first connection member (74), spaced, parallel, longitudinally extending plates (76) and a second connection member (78). The plates are connected to the connection members for pivotal movement about vertical axes, and the connection member of adjacent links are connected to each other for pivotal movement about horizontal axes thereby accommodating horizontal and vertical flexure of the conveyor chain. The conveyor chain (70) is actuated by a drive mechanism (180) including a drive chain (198) and chain engaging members (206) carried thereby which engage the conveyor chain along an arc having a substantial radius, thereby propelling the conveyor chain through the track (110) without subjecting the conveyor chain to periods of high acceleration.
