  • Patent number: 6068133
    Abstract: A system for separating non-magnetizable metals from a mixture of solid with a feed device; an endless conveyor belt with belt drums supported on a frame, of which the head drum at the discharge end is provided with a driven, eccentrically mounted and adjustable magnet rotor; and a separation area downstream of the head drum. To improve the degree of separation achieved, the system is provided with a vibrating channel (2) with an additional slope; means for adjusting the speed of the conveyor belt (3); means for generating a variable force of repulsion (Fvar); a controlled rotational speed adjustment unit (nvar) for the magnet rotor (3.4); and adjustable separating elements (4.1, 4.2, 4.3), each of which is located between two adjacent throwing parabolas of the separated fractions.

  • Patent number: 4588003
    Abstract: A refuse packaging assembly of the kind comprising a refuse press having a pressing plunger which is axially movable in a pressing box, and a container which is adapted to be connected to the outlet end of the pressing box in order to be filled with refuse by the plunger, the container having a closure plug which is uncoupled from the container and coupled to the plunger for movement therewith when the container is connected to the press. The container carries at least one spring loaded pin which is biased into a coupling aperture in the closure plug to couple the two together, and the plunger carries at least one weaker spring loaded pin which aligns with the coupling aperture when the container is moved into position for connection to the press and the plunger is moved to a coupling position.

  • Patent number: 4466345
    Abstract: A machine for pressing and binding bales (6) of refuse with wire is provided with a binding mechanism comprising a wire cutting device (14), a wire twisting device (13) and a binding needle (19) which is movable across a rear face of the bale for forming a wire loop (8a, 8b), a part of which is joined by the twisting device (13) to the tail end (8c) of a previously formed loop of wire to form a band extending around the bale. In order to avoid waste of wire occurring in the binding of overlength bales and to ensure functionally reliable and trouble-free binding of the bales, the binding needle (19) together with the wire loop (8a 8b) are capable of being transported parallel to the pressing direction (P) until they are adjacent the position adoped by the twisting device (13).

  • Patent number: 4279557
    Abstract: A method of loading bales of refuse from a horizontally acting baling press on to a transport vehicle without the use of a separate loading machine such as a fork-lift truck comprises aligning the transport vehicle with a discharge from the press; moving each bale as it is discharged from the press on to a transverse table; moving some of the bales laterally so that the bales are formed into two or more rows side by side aligned with the transport vehicle and moving the two rows of bales progressively forwards as successive bales are discharged from the press so that the rows are moved from the transverse table on to the vehicle and the rows are built up on the vehicle until the vehicle is fully loaded.

  • Patent number: 4125068
    Abstract: A baling press for the production of bound bales of scrap material such as refuse is of the kind which comprises a press box, a press plunger which is movable through the press box to compress refuse fed to the box from a hopper the outlet of which is closed by the plunger as the plunger moves through the press box in a pressing stroke, a press channel which forms an extension of the press box and into which the pressed bales are pushed by the plunger and a binding mechanism disposed between the press box and the press channel for binding the bales as they are pushed into the channel. The press is provided with a separator slide which is movable transversely to the direction of movement of the press plunger and is disposed between the press box and the press channel just upstream of the binding mechanism considered in relation to the direction of pressing movement of the plunger. The slide is movable between an operative position in the path of the plunger and a retracted position clear of this path.
