ABSTRACT:
If the next charge to be stuffed into the baling chamber has not yet reached the desired size and density by the time the stuffing fork and compacting plunger are ready to begin their next operating cycles, the plunger and the fork are temporarily deactivated until the charge reaches full size and density. Thereupon, the fork stuffs the entire charge into the baling chamber in a single cycle of operation for compaction by the plunger. The baler is loaded from the bottom of the baling chamber through an upwardly curved duct that serves both as an accumulating chamber and as a precompression area into which the charge is progressively packed by a rotating, retractable finger drum at the lower end of the duct. The plunger closes the top of the duct during such accumulation and pre-compression, and in order to provide ample time for the plunger to retract from the duct when the stuffing cycle commences, the fork moves slowly at first but then quite rapidly once the plunger has retracted. Actuation of the plunger and stuffing fork occurs automatically in response to obtaining the predetermined density of the accumulated charge as sensed by a pressure-sensitive device on the loading duct.
