  • Patent number: 6367377
    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.

  • Patent number: 6041699
    Abstract: A ram driving device for a press machine having: a ram; a horizontal drive axle (33) rotatably provided horizontally in a frame (3) of the press machine; a motion converting mechanism (35, 63, 83) associated with the horizontal drive axle, for converting a rotational motion of the horizontal drive axle into up-and-down motion of the ram (29); and a plurality of servomotors (43, 47) linked with the horizontal drive axle, for rotating the horizontal drive axle in synchronism with each other, to drive the ram up and down. The motion converting mechanism is a connecting rod (35); and a link mechanism (63) driven by a ball screw (61) and a nut member (77); and an eccentric ring cam (33) and a cam follower (91). Since the ram can be driven by a plurality of the servomotors synchronously, the device can generate a large press power of various moving stroke and various moving speed freely, without increasing the maintenance cost thereof.

  • Patent number: 5025719
    Abstract: A trash compactor includes a receptacle with a receptacle opening, a closure member, and a collapsible compacting mechanism mounted in the closure member. The closure member is adapted to be secured over the receptacle opening in a compacting position. With the closure member in the compacting position, the compacting mechanism is adapted to be operated, preferably driven by an electric drive motor, so as to extend a compacting head into the receptacle through the receptacle opening to compact trash received therein. The compacting mechanism is also adapted to retract the compacting head substantially from the trash receptacle. A drive motor control system controls the operation of the drive motor in driving the compacting mechanism. Once the compacting head is retracted from the receptacle the closure member is adapted to be released from the compacting position thereby exposing the receptacle opening so that more trash may be deposited into the receptacle for compacting.

  • Patent number: 5024151
    Abstract: Disclosed is a refuse compactor particularly designed for aircrafts, which comprises a compaction chamber having a movable wall panel that extends parallel to one of the side wall of the compaction chamber, and can be moved away from this side wall through a very simple mechanism which is operated either directly by a hand-lever or indirectly through the service door of the compactor cabinet when this service door is closed for refuse compaction into a container. In both cases, the very purpose of this lateral motion of the movable wall panel relative to the adjacent side wall is to release the pressure of the refuse container inside the compaction chamber after completion of the compaction, and thus makes this container easily discardable into a storage chamber if any, or out of the compactor. The operation of the movable wall panel is exclusively mechanical and is therefore very simple and reliable.

  • Patent number: 5001977
    Abstract: A removable, self-powered trash compactor particularly suited for aircraft tray carts. The compactor includes a rechargeable battery to power a motor that drives a screw drive connected with a scissor type extension linkage attached to a platen designed to permit the passage of liquids around said platen to minimize pressure exerted on walls and floor of container, carts and carriers. The food service tray guides support a plastic or fiberboard sheet to restrain resilient waste matter from returning to its original shape and permitting a disposable flexible liner to interfold underneath the compactor and surround the compactor until the first cycle wherein the liner unfolds and encompasses the cart, carrier or container space, thereby obtaining the compactor to support the disposable liner and permitting the fitting of an interfolded cover over the entire compactor inside the liner to permit the compactor to compress waste and keep waste matter from contact with the compactor mechanisms.

  • Patent number: 4548132
    Abstract: A refuse compactor of the type having a receptacle drawer removably contained within a cabinet wherein refuse is compacted by a ram to a fraction of its normal volume. The ram includes a refuse-compressing platen actuated through a toggle linkage to which force is applied by a single screw driven by an electric motor coupled to the screw through a reduction drive. The screw, motor and drive train are carried as a unit by the toggle linkage and move bodily therewith. Improvements are provided in the cabinet, receptacle drawer, compacting mechanism and mounting framework for the same which embody many structural and operational simplification features greatly reducing the size, weight and cost of the compactor.

  • Patent number: 4100850
    Abstract: A trash compactor has a rotatable lead screw and stationary nut for raising and lowering the compacting ram by rotation of the screw. A housing surrounds the nut for preventing rotation of the nut with respect to the screw while permitting limited pivotal movement of the nut with respect to the housing responsive to eccentric compaction forces applied to the compacting ram. The housing is distortable for the same reason and to permit absorption of shocks arising from compaction. The nut may be formed of a self-lubricating plastic. The drive mechanism may be used in a trash compactor having an extensible linkage of the scissors jack or lazy tongs type in which the lead screw is journalled in one of the intermediate junction points of the linkage. The housing containing the nut is located at the other of the junction points so that rotation of the screw extends and retracts the linkage.

  • Patent number: 4024806
    Abstract: A trash compactor has a compacting head supported by two sets of links, each set having a pair of links pivotally interconnected by a member common to both pairs and spacing the two sets of links apart. Corresponding ends of the links are pivotally connected to the head and means connect the other ends of the links to the compactor in a manner enabling the linkage to be unfolded to extend the head into a compacting position or retracted therefrom. Vertical screws, rotated by a reversible drive are threaded through the pivot member to effect such folding and unfolding of the linkage. The ends of the pivot member are within vertical guides and the linkage includes stabilizing links connected to the head.

    Abstract: The trash compactor has a throat above the chamber in which the trash receiving unit is located. The trash receiving unit consists of a pan and a container, both dimensioned so that their walls are shielded by the throat. The pan fits the chamber with its walls spaced from the walls of the housing and receives a trash bag within it. The container is open at the top and bottom with its walls upwardly and inwardly tapering with its lower end fitting within the bag and holding it bottomed against the pan. Both the pan and the container are of a plastic having a good memory and they are detachably interconnected. A carrying strap enables the unit or the pan with the bag therein and with the container removed, to be carried to a pick-up or disposal site.
