  • Patent number: 7905356
    Abstract: A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid. The components are exposed to a first essentially horizontal force (P1) in a first direction (D1) enforced by a flow of the liquid in the fractionation vessel and to a second essentially horizontal force (P2) in a second direction (D2), which is substantially different from the first direction (D1). The combined impact of the forces (P1; P2) on the components spreads the components and leads them to at least two collection areas. Products of varying buoyancy may thus be treated separately.

The classification system is made of a hopper having an inlet, including a spillway opening defining a lowermost portion of the hopper inlet, and an outlet formed along a lower portion of the hopper and contained in a plane at an angle of about 50 degrees from horizontal. A conveyor covering the outlet includes substantially rigid cleats extending into the hopper for agitating the debris and for transporting heavy material, such as glass bottles, out of the hopper outlet. Agitation of the debris causes the heavy material to drift to the lower portion of the hopper and the light material to rise to the top portion and flow over the spillway. A second conveyor positioned beneath the spillway catches the light material and carries it to another location.

    Abstract: Apparatus and method for performing multiple level sortation operations upon a number of randomly ordered garments. The garments are identified by unique identification data, which can be scanned and entered into a computer. The computer remembers the order in which garment identification data has been. The garments are then transferred in their entered order to a first sortation assembly in which a rotating wheel assembly accepts and selectively releases garments during indexed rotation of the wheel at one of a number of stop points. Each stop point has associated with it a receiving rail, where each rail represents a different group within a first sortation level. The computer recognizes which receiving rail is the correct rail for each garment according to the first sortation criteria and signals the release of the garment at the correct stop point. The garments collected on each receiving rail comprise a group of first sorted garments according to the first sortation criteria.
