ABSTRACT:
An automatic packaging machine transports an object over a path having a freedom for both horizontal and vertical movement. Horizontal rails support a pair of guide blocks positioned to slide over the rails. Each of the guide blocks has a pair of spaced parallel slots with a T-shaped cross-section confronting individually associated one of the rails. A replaceable wear resistant track is slidably captured within each of the T-shaped slots, to slide over an individually associated one of the rails. A vertical support bar interconnects the second guide blocks. An upper and a lower U-shaped block is attached to the vertical support bar at vertically spaced locations. A keeper is secured over the open space of each of the U-shaped blocks. A block of wear resistant material is positioned in a recess in each of four interior surfaces of the U-shaped block and keeper, a slidable vertical bar being captured and sliding within the embrace of the U-shaped blocks. There is enough play within the sleeve member for the slidable vertical bar to swing out of a sleeve member having a keeper removed while the other keeper remains in place, to enable the wear blocks to be replaced. The slidable vertical bar carrys the object over the path.
