Abstract: Disclosed is a double-motor double-station screw press, comprising two sets of screw pair mechanisms on both sides thereof, i.e., first and second screw pair mechanisms, where in the first screw pair mechanism, a first lead screw is driven by a resultant movement synthesized by first and second motors through a first differential gear train; in the second screw pair mechanism, a second lead screw is driven by a resultant movement synthesized by the first and second motors through a second differential gear train; a first slider and a second slider in the press work symmetrically; a transmission mode between the second motor and the second differential gear train is switched by controlling a steering switching apparatus, such that the second motor can assist the first motor during a single-cylinder pressing process to increase the output pressure, but also it is convenient to adjust a relative positions of two cylinders.

Abstract: A compactor/baler for compacting materials includes a frame defining a compacting chamber, a platen movably mounted to the frame, a loading gate movably mounted to the frame and a control panel including a biometric reader having a biometric scanner. The platen is movable within the compacting chamber and the loading gate is movable from a closed position blocking access to the compacting chamber and an open position exposing the compacting chamber. The control panel is actuable between a locked configuration and an operational configuration. The biometric reader is designed to accept a biometric attribute of a user and to actuate the controller between the locked and operational configurations. The biometric reader actuates the controller to the operational configuration if the biometric attribute matches a stored biometric attribute. The control panel prevents the loading gate from moving to the open position when the controller is in the locked configuration.

Abstract: A reciprocating press for forming workpieces includes a tilting table that supports the workpiece and positions it with respect to the press tooling as the press closes, and then is pivoted upward into an inclined orientation as the press opens so that the finished workpiece falls down the table and is automatically discharged from the press. A preferred embodiment has a lifting arm attached to an upper reciprocating press member that carries an upper forming tool such as a punch. The lower end of the lifting arm engages the tilting table such that the table is pivoted about a horizontal axis in concert with the upward and downward movement of the reciprocating press member. The press preferably also includes a safety door that is automatically closed before the press fully closes and is opened again as the press opens such that operator access to the moving press parts is prevented by the door during a press cycle.

Abstract: A refuse compactor has a housing for containing a garbage receptacle, and a compression unit for compacting the refuse in the compaction unit from time to time. The compactor has a sensor for sensing the approach of persons wishing to deposit garbage. This sensor causes the opening of an inlet door. It has a second sensor, for gauging the level of refuse in the receptacle. When a sufficient bulk is collected, then the compression unit operates to compact the refuse. The compression unit is subject to three limiting conditions, the first being a “receptacle full” limit, the second being a load limit, and the third being a stroke limit. The compaction unit used is a scissors mechanism having one side of the scissors mechanism held in one plane.

Abstract: A compacting system including a double action vertical ram pivotally mounted within a container. The container includes a front wall, a rear wall, a pair of side walls, a floor and a lid. An opening in the front wall allows refuse or other material to be deposited into the container. A hingedly mounted door covers the opening. The ram includes a pivotally mounted compression plate and a cylinder mounted to one of the side walls with one end thereof mounted above said plate. A shaft extends from a housing of the cylinder and is attached within the container to the plate. In a compaction cycle, the compression plate can travel from a "vertical" position to a substantially "horizontal" position, and compacts the refuse between a lower surface of the compression plate and the floor. A power unit located outside the container provides power to actuate the cylinder. A magnetic safety switch and a door interlock device provide safety features for the compacting system.
