PACKAGING MACHINE

WIPO Patent Application WO2005085071

A3

A packaging machine (10) includes a grouper section (14) having changeable lane sizes and a dual servo grouper (110) that separates product into product sets and allow the product sets to accelerate to the lane chain speed in a controlled manner. The grouper section (14) further includes disappearing lugs (60) that pivot into the lanes via a cam (64) surface provided in the lanes. The product rides upon a raised surface of the cam surface as the lug (60) pushes the product set together down the lane, thus ensuring that no gaps are provided between product set members. A gripper/grid section (16) of the packaging machine (10) includes a bars (420) that travel about a carousel with a gripper head assembly (200) and a grid assembly (300) pair moving up and down the bars (420) as defined by cam surfaces within the gripper/grid section (16). The grid section (300) is presented below the product (20) set such that the product set is fed through the grid section (300) in a one-way trip into a case (12). The gripper head assembly (200) cam device and the case feed section (18) both include height adjustment assemblies (500).
