Abstract

A packaging machine includes a grouper section having changeable lane sizes and a dual servo grouper 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 further includes disappearing lugs that pivot into the lanes via a cam surface provided in the lanes. The product rides upon a raised surface of the cam surface as the lug pushes the product set together down the lane, thus ensuring that no gaps are provided between product set members. A gripper/grid section of the packaging machine includes a bars that travel about a carousel with a gripper head assembly and a grid assembly pair moving up and down the bars as defined by cam surfaces within the gripper/grid section. The grid section is presented below the product set such that the product set is fed through the grid section in a one-way trip into a case. The gripper head assembly cam device and the case feed section both include height adjustment assemblies.
