<p>A load compactor for compacting cornpressible loads of a carton loading machine is provided with compactor members which reciprocate vertically and are located directly above the load as it is driven through the loading station. The compactor members are mounted on a compactor conveyor which consists of a pair of endless chains. A plurality of carriers are mounted on the endless chains at spaced intervals. Carriages are slidably mounted on each carrier and have a compactor head at their lower end which bears against the compressibie load. A guide track is provided for guiding the movement of the carriages toward and away from the load. The guide track has a forward run which is vertically spaced from its return run so that the heads of the compactors are vertically spaced from one another during the forward run and the return run and overlap one another to achieve a compact lateral configuration. The guide rails also include an elevator rail which extends along the forward run and an elevator mechanism for elevating the elevator rail so as to raise the compacting heads out of engagement with their associated load to clear a jam or the like.</p> |
