  • Patent number: 6550608
    Abstract: A carton feeding system for feeding cartons into a packaging machine is disclosed. The carton feeding system includes a frame in which a carton feeder is rotatably mounted and a carton guide assembly. The carton guide assembly includes a pair of spaced guide tracks along which guide chains are moved to engage and urge the cartons along the carton feeding system toward a drop point overlying a series of products passing therebeneath. A pair of spaced chute plates receive and support the ends of the cartons as the cartons are released by the carton feeder and are urged by the guide chains along a feed path toward the drop point and engagement with a series of products passing through the product-packaging machine.

  • Patent number: 6497084
    Abstract: 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.

  • Patent number: 6381927
    Abstract: 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.

  • Patent number: 6371287
    Abstract: 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.

  • Patent number: 6341689
    Abstract: 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.

  • Patent number: 6315111
    Abstract: 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.

  • Patent number: 6311457
    Abstract: 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.

  • Patent number: 6308502
    Abstract: 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.

  • Patent number: 6273242
    Abstract: A rotary transfer apparatus, comprising: a frame structure; a rotatable main shaft supported by the frame structure; a primary body connected to the main shaft; at least one first planetary shaft rotatably connected to the primary body and rotating in relation to the main shaft; a secondary body connected to each first planetary shaft; a second planetary shaft rotatably connected to each secondary body and rotating in relation to the first planetary shaft; an article transfer mechanism connected to each second planetary shaft; and an in-line cam mechanism. The article transfer mechanism is adapted for picking and placing articles, and has at least one stem connected to the second planetary shaft. Each stem has a distal end whose motion defines a product path about the main shaft. The product path has at least one apex at which point the distal end of the stem moves in an in-line motion. The in-line cam mechanism is adapted for extending the in-line motion at the apex(es) of the product path.

  • Patent number: 6240707
    Abstract: A carton opening assembly for a continuous motion packaging machine directs opposed carton engaging plates perpendicular to opposite side walls of a collapsed carton moving through the opening assembly. A vacuum is applied to the opposed carton side walls when the assemblies engage the carton. One or both of the opposed carton engaging assemblies are retracted to filly open the carton, which is then transferred to a conveyor that transports the carton to the next workstation of the packaging machine. The carton opening operation is accomplished while tracking the carton movement through the carton opening assembly.
