  • Patent number: 11905052
    Abstract: A system for forming retained container groups from an arrayed container group (ACG) via application of an adapted retainer blank to the ACG is generally provided. The system is advantageously characterized by a container conveyance apparatus for conveying arrayed container groups, a supply of retainer blanks from which retainer blanks are dispensable, and a processing station characterized by a segment of the container conveyance apparatus, a die block, for receipt of a dispensed retainer blank from the supply of retainer blanks, and a robotic arm equipped with an end of arm tool (EOAT).
    Type: Grant
    Filed: April 13, 2022
    Date of Patent: February 20, 2024
    Assignee: Douglas Machine Inc.

  • Patent number: 8647247
    Abstract: Among other things, a case forming system is provided. The system includes a conveyance apparatus for conveying case precursors along a conveyance path and a case set-up apparatus characterized by a case forming member. Upstream case precursors are conveyed along the conveyance path for operation thereupon by the case forming member. A case forming mandrel of a mandrel assembly is movably mounted in relation to the conveyance apparatus for continuous motion with respect thereto. The continuous motion is delimited by travel of the case forming mandrel between an upstream locus and a downstream locus of the conveyance path, and reversible extension of the case forming mandrel towards case precursors during travel between the upstream locus and the downstream locus of the conveyance path.

  • Patent number: 5628614
    Abstract: 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).
