Patent number: 5628614Abstract: A continuous motion stacking apparatus (10) is disclosed including a positive drive device (14) which places abutting products on a conveyor (12). When the leading series of products is detected to have reached a predetermined position by a sensor (94), the series of products are pushed from the conveyor (12) by a pusher plate (32) which has a first movement component equal to the conveying speed parallel to the conveyor (12) and a second movement component perpendicular to the conveyor (12). The series of products are pushed onto a shelf (30) simultaneously moving perpendicular to the conveyor (12) with the pusher plate (32). When the shelf (30) retracts, the products fall onto a vertically, movable platform (24) or products supported thereon. A guide (34) moves forward at the conveying speed parallel to the conveyor (12) to keep the remaining products on the conveyor (12) and to keep the last product of the series being pushed from the conveyor (12) parallel to the conveyor (12).Type: GrantFiled: March 16, 1995Date of Patent: May 13, 1997Assignee: Douglas Machine Limited Liability CompanyInventors: Irvan L.

Patent number: 5558614Abstract: Apparatus (200) for opening the closure flaps (22-25) of a carton (12), for presenting the carton (12) for loading, and for closing the closure flaps (22-25) is disclosed including a carrier (202) which initially receives the carton (12). The carrier (202) carries the carton (12) into a carriage (226), with the carton (12) sandwiched therebetween. The closure flaps (22-25) are opened by a device (242) including fingers (254-257) which are pivoted to an expanded position after their insertion through an opening (27) in the closure flaps (22-25). An elevator (212) raises the carton (12) in the carriage (226) while the carton (12) is still under compression, with suction cups (56,171-173) then being attached to the closure flaps (22-25). The carriage (226) can then be moved to a loading position and back where the closure flaps (22-25) of the loaded carton (12) are fan folded by a device (120). The elevator (212) can then be lowered where the closed carton (12) can be pushed therefrom.Type: GrantFiled: February 18, 1994Date of Patent: September 24, 1996Assignee: Douglas Machine Limited Liability CompanyInventors: David L.

Patent number: 4779715Abstract: A lane divider for automatically dividing a single row of objects into a plurality of rows is shown in its preferred form as including a diverting conveyor having an outfeed end movable between a plurality of lane positions. The diverting conveyor includes belts located on the faces of first and second elongated pivot bars to form an object passage channel. The elongated pivot bars are pivotally mounted in a parallelogram arrangement about fixed axes adjacent the infeed end and about axes adjacent the outfeed end which are reciproated. Opposite point deflection between the belts is minimized by changing the relative length of the drive chain between the drive shafts of the belts in response to the pivoting of the elongated pivot bars by pivotally interrelating the elongated pivot bars to a plate pivotally mounting idler sprockets on opposite sides of one of the drive shafts.Type: GrantFiled: October 7, 1987Date of Patent: October 25, 1988Assignee: APV Douglas Machine CorporationInventor: Irvan L.
