Patent number: 6497084Abstract: There is provided transport apparatus for carton blanks 11. The blanks are delivered to a pair of rotating nip rollers 17 by using a segment wheel 15 and a swinging suction arm 16. The nip rollers 17 are drive at a predetermined speed so as to deliver the blanks 11 between two pairs of endless belts 18, 19 which are driven at the same speed as each other, the speed of the belts being slower than that of the nip rollers 17. The blanks 11 are, therefore, received by the nip rollers 17 in a pitched manner but the relative speeds ensures that the blanks are transported by the endless belts 18, 19 in an unpitched, end to end relationship.Type: GrantFiled: July 9, 1999Date of Patent: December 24, 2002Assignee: Riverwood International CorporationInventor: Johannes Jänen

Patent number: 6381927Abstract: A flap folding assembly for engaging a work piece, such as a paperboard carton flap, and moving that flap into a desired position. The flap folding apparatus can be used in a continuous motion packaging machine to engage a sleeve type carton flap as the carton is transported downstream through the package machine. The apparatus is operated in timed relationship with the machine's carton conveyor either by mechanically interlinking the apparatus to the main machine drive, or by the use of a servo drive operated from and controlled by the packaging machine's main controller. The flap folding apparatus includes a vacuum cup driven in a circular path by a drive mechanism comprised of two spaced gears which are driven in the same direction of rotation.Type: GrantFiled: October 25, 1999Date of Patent: May 7, 2002Assignee: Riverwood International CorporationInventors: Frank Moncrief, Jeff Disrud, Timothy Wayne Hendricks

Patent number: 6371287Abstract: The present invention relates to a basket carrier that provides full protection for the bottles being carried, and which can be glued on a straight-line gluer. The provision of nicks (i.e., temporary bridges) between the handle panels and the side walls serves to keep the handle panels in proper alignment during the folding and gluing operation on the gluer. These nicks are easily broken when the carrier is opened to receive bottles in the bottling plant. The present invention also utilizes nicks between the partition panel and the handle ply to hold them in contact but yet prevent bunching of paperboard during the folding and gluing process.Type: GrantFiled: October 3, 2000Date of Patent: April 16, 2002Assignee: Riverwood International CorporationInventors: Marty Jones, Robert L. Sutherland, Jean-Manuel Gomez

Patent number: 6341689Abstract: This invention relates to carriers that have partition panels attached to one or both ends of the carrier via an end flap. All of the outside panels of these carriers are folded about lines that are parallel to the longitudinal direction of the gluer on which the carrier is folded and glued. All of these carriers have multi-ply handles in which none of the plies are foldably attached to each other at their top edges. Nicks may be provided between the handle panels and the side and end flaps to hold the carrier in proper position during the folding and gluing operation. This invention also relates to a method of folding and gluing the carriers on a straight-line gluer.Type: GrantFiled: September 15, 2000Date of Patent: January 29, 2002Assignee: Riverwood International CorporationInventor: Marty Jones

Patent number: 6315111Abstract: A basket-style carrier which includes a top panel. The end panels are comprised of two separate sections, each of which is connected to a center panel, and are spaced from the top panel. The top panel is foldably connected to the side panels and includes a handle. Vertical folds in the end panels allow the end panels to follow the contour of adjacent packaged bottles. In three embodiments the top panel includes bottle neck openings. In a fourth embodiment partial upper end panels connected to the top panel are spaced from the lower end panels. Gusset panels connected to upper end panel flaps and to glue flaps connected to the side panels automatically cause the upper end panel elements to fold into place during the carrier forming operation.Type: GrantFiled: November 13, 1997Date of Patent: November 13, 2001Assignee: Riverwood International CorporationInventor: Robert L. Sutherland

Patent number: 6311457Abstract: A carton feeder for a continuous motion packaging machine includes a speed compensation controller and a solenoid dual valve assembly, which enable the feeder to operate at higher speeds. The dual valve assembly includes a vacuum valve coupled to an air pressure valve which is controlled by an electronic controller. The speed compensation assembly is electronically connected to the valve controller, and includes an encoder driven by the feeder and a programmable limit switch for receiving data from the encoder and transmitting control signals to the valve controller. The method of operation includes detecting the position of the selector and transmitting position data to the limit switch. The limit switch calculates optimum valve actuation timing based upon both programmed information and data from the encoder, and transmits the control signals to the valve controller.Type: GrantFiled: August 3, 1999Date of Patent: November 6, 2001Assignee: Riverwood International CorporationInventors: Kevin May, James W. McCoy

Patent number: 6308502Abstract: A loader arm assembly for use in a packaging system, comprising an arm, a housing, and a load jam detector. The housing is operably connected to at least one motive mechanism, and is adapted for moving the arm to load product into a package. The arm has both a latched state and a released state with respect to the housing. The arm normally is in the latched state to load product into the package, and enters the released state to relieve pressure upon detecting the load jam condition. The arm includes a base plate and a loading head. The housing is formed with a guide passage that is adapted for receiving the base plate. The load jam detector preferably includes at least one detent adapted for holding the base plate with respect to the housing in the latched state. The detent preferably is formed by a tip of at least one plug extending through the housing to the guide passage. The tip is adapted for applying a holding force against the base plate.Type: GrantFiled: December 29, 1999Date of Patent: October 30, 2001Assignee: Riverwood International CorporationInventors: Allen Olson, Gerald Geisenhof
