  • Patent number: 7823718
    Abstract: A conveyance device is configured to carry a product. The conveyance device includes a first path configured to carry the product in a first direction, a second path configured to carry the product in a second direction, and a transfer assembly positioned adjacent to a portion of the first path to facilitate transfer of the product from the first path to the second path. The conveyance device also includes a guide system configured to move the transfer assembly along the first path. The guide system includes a base positioned proximate the first path and the second path and an arm coupled to the base and extending above a portion of the first path and a portion of the second path. The arm is configured to move in a first manner and a second manner relative to the base. The transfer assembly is movably coupled to the arm.

  • Patent number: 5556041
    Abstract: Disclosure is made of baled material disintegrator, or debaler or pull apart apparatus having a bale conveyor and conveyor chute and at the outlet of the conveyor, a multi picker wheel debaler cartridge suspended on a swing shaft or axle, and hydraulic piston means connected to the debaler cartridge to swing the cartridge to and from the bale to be disintegrated or debaled, and further disclosure is made of removal from a bale of material such as paper, the bale binding wire scrap on breaking of the wire by action of debaler cartridge picker wheels, and a scraper bar with tooth segments extending to the tooth wheel shafts and the teeth of the scraper bar straddle the picker tooth wheels to remove the scrap wire from the shafts of the picker cartridge and collection of the cut bale binding wire on a magnet mount bank, set on an incline at the outlet of the debaler cartridge, and the magnet bank overlaid by an endless conveyor belt, and removal of the binding wire scrap, or other tramp iron from the disintegrat

  • Patent number: 5324389
    Abstract: A method of pulping baled waste material includes breaking up the bale and applying the broken bale to a fluffer or shredder to form a fluffed waste paper product containing heavy and light contaminants. This product is applied to an air separator from which heavier non-paper contaminant fraction is removed, and the remaining product is applied to the inlet of a vortex separator which removes a light reject fraction. A second accepts fraction is then water soaked and applied to the inlet of a series of drum-type pulpers. The invention further includes a drum-type pulper in which an axial shaft has radially-extending arms or buckets which dip into a pool of stock from waste paper in which the buckets sweep the interior of the drum, lift a quantity of the mixture from the pool, and allow the same to drop back into the pool. Vanes on the buckets cause the mixture to move axially in the drum from an inlet to an outlet.
