Abstract: A vertical form fill and seal apparatus, for packaging particulates, includes a package sealing assembly that has opposed sealing jaws operatively coupled to each other by mechanical connection at a common pivot point. A first jaw actuator is mechanically coupled to the opposed sealing jaws to pivot the jaws in a controlled manner about the common pivot point. A second actuator is mechanically coupled to the package sealing assembly and is configured to impart controlled reciprocating motion to the package sealing assembly. A controller is configured to control the first actuator and to control the second actuator thereby causing the jaws to describe a preset locus of travel, allowing flexibility of type of bag being made without change-out of jaws. The packaging film may move continuously, or may optionally be controlled to move intermittently through the VFFS.

Abstract: An article accumulation pattern building load plate assembly is provided. The assembly includes a deck for support of patterned articles, a stop for retaining deck supported articles, and spaced apart guides adjustably positionable in relation to the deck so as to transversely guide articles thereacross towards the stop. Articles of the patterned articles are received at an ingress portion of the assembly from a metered article source, the articles extendable at least across a width of the deck in a direction transverse to an article ingress direction. The stop is adjacent the deck, extending in a direction transverse to the article ingress direction, the stop delimiting an egress portion of the assembly.

Abstract: A vacuum table (18) includes an introduction section (102) in fluid communication with a vacuum chamber (120) and a compartment (139) dividable by an adjustment partition (156) into primary and secondary vacuum chambers (139a, 139b). Adjustment plates (130) having adjustment apertures (138) are positionable over apertures (128) of the conveying surface (100) of the vacuum table (18) generally perpendicular to the conveying direction. Film (20) extends from between the nip of pinch rollers (12, 13) to the conveying surface (100) and is tensioned therebetween to be cut in excess of 105 cuts per minute by a servo motor controlled rotary cutter (30) which stops after each cut. The shaft (32) of the rotary cutter (30) includes a bore (310) extending from the idle end to provide servo-control loop stability.

Abstract: An article metering system is generally provided. The system is primarily comprised of a conveyor section, for receipt of a bulk flow of articles and conveyance of spaced apart metered article groups downstream of an ingress portion thereof, and an article metering station characterized by an article metering apparatus characterized by a drive assembly and a driven member driven thereby. The driven member includes an end effector for select positioning between adjacent articles of articles of the bulk flow of articles received by the conveyor section in furtherance of delimiting a downstream spaced apart metered article group characterized by a select number of columns. The drive assembly includes cooperatively driven servo drives to effectuate travel of the end effector in either of a downstream article flow direction or an upstream article flow direction, and an up/down direction in relation to articles of the bulk flow of articles received by the conveyor section.
