Abstract:
In combination with a waste compaction device wherein the compaction device includes:a receiver having an opening for receiving paper waste crowded into the opening; a chute having a bottom, two parallel sides and an open top to receive waste material and extending from the opening of the receiver away from the receiver to define a volume to be compacted, the chute ending at the opening of the receiver; a platen extending between the two parallel sides of the chute and moveable along the chute over the bottom of the chute for crowding material placed into the open top of the chute into the receiver; an expandable ram fixed relative to the chute away from the opening of the receiver and expandable along the chute for moving the platen during crowding of the waste material from the chute into the receiver; and, a plate for sealing the open top of the chute behind the platen and over the expandable ram when the platen is moved forward along the chute to crowd material into the receiver; an improvement to the compaction device comprising: a first bin formed overlying the chute having a first bin bottom occupying less than a full area of the open top of the chute; the first bin communicated to a pneumatic waste transport system; a first electric eye for actuating the platen when the first bin is filled with material sufficient to permit compaction and to retain in the first bin a remainder of material; a second bin formed overlying the chute having a second bin bottom occupying a remainder of an area of the open top of the chute; the second bin communicated to a mechanical waste transport system; a second electric eye for actuating the platen when the second bin is filled with material sufficient to permit compaction and retain in the second bin a remainder of material whereby upon retraction of the platen, the chute is opened to receive material from either the first bin or the second bin for crowding into the receiver there remains respectively in the second bin or the first bin a sufficient remainder of material to prevent pneumatically induced escape of waste material.
