  • Patent number: 6799684
    Abstract: A counting and portioning system which counts discrete articles that conform to predetermined specifications into lots having a predetermined number of articles or a target volume. The system includes at least one portioning bin positioned to receive articles from a conveyor. The at least one bin has at least first and second outlet gates for emptying articles into separate respective first and second locations. A scanner detects and maintains a count of articles that are received in the at least one portioning bin and fall within the predetermined specification. The detector unit generates an out-of-specification signal when an article or group of articles received in the at least one portioning bin falls outside the predetermined specification. A control unit causes the first outlet gate to open when the count or volume of articles is equal to the predetermined number and causes the second outlet gate to open in response to receipt of an out-of-specification signal.

  • Patent number: 6629611
    Abstract: A reciprocating rod of the ejector is borne in a non-sliding state by permanent magnets on the reciprocating rod and permanent magnets surrounding the reciprocating rod. The reciprocating rod linearly projects out and retracts by the reciprocating components which cause the reciprocating rod to reciprocate by the driving signals from the driver circuit. A slanted surface is provided at the foremost end of the reciprocating rod. When the granular objects to be ejected flow-in continuously, the projecting-out action takes place correspondingly with the leading granular object to be ejected and, after the following granular object(s) to be ejected has been ejected, the retracting action takes place.

  • Patent number: 5562214
    Abstract: An apparatus for optically sorting small objects such as beans has an annular analysis head with an opening through which the objects fall. Three sets of optical fibers are positioned around the analysis head opening. A first set receives radiant light reflected from the falling objects. This reflected light is digitized and input to a comparator where the reflected light is compared to a reference value and a determination as to the quality of the object is made based on color. The second set of fibers is connected to an infrared light source and transmits a curtain of light across the opening, intercepting the travel of the objects. The third set of fibers receives the infrared light and is connected to a light detector which detects when objects pass through the curtain of light. The curtain of light is preferably wider than the objects. The light detector outputs a signal having peaks caused by the widest portions of objects passing through the light curtain.

  • Patent number: 5448363
    Abstract: In a machine for sorting food pieces such as potatoes the pieces are dropped one at a time through scanned laser beams that sequentially scan over its surface on all sides. Detectors measure laser light reflected from the food as the beam scans over the surface; variations indicate bad spots. To determine when the beam is not shining directly onto the food piece, a ribbon-like direct light detector is circumferentially deployed about the test zone. The reflected light is changed to electric signals and is analyzed by the microprocessor to decide if the food piece is to be deflected by an air jet. When the direct-light detector registers an un-interrupted laser beam, the microprocessor ignores the reflected light signals; that is, the direct light signal gates the reflected light signal. The reflected-light detector may be a bundle of up to 50 optical fibers having the fiber ends regularly disposed about the ring, so as to detect the light intensity at various evenly-spaced angles around the test zone.

  • Patent number: 5339965
    Abstract: A sorter for sorting transversely-spaced articles moving along a direction of travel employs an array of fluid nozzles aligned transversely to the direction of travel for separating some of the articles from others, according to differences in their physical characteristics, by selectively directing respective streams of fluid toward some of the articles to deflect them from the direction of travel. The nozzles are arranged in a substantially linear transverse alignment relative to the direction of travel, each nozzle being connected to a respective selectively operable fluid supply valve. The valves are arranged in a nonlinear array in a common plane extending generally in the direction of alignment of the nozzles, and are connected to the respective nozzles by flexible tubes of equal length which interface the nonlinear array of valves with the linear transverse array of nozzles. The tubes are embedded in a hardened polymeric material which also forms the nozzles.

  • Patent number: 5092470
    Abstract: In a method and apparatus for grading objects according to their size, the objects are advanced along a broad, flat and divided conveyer path. Image data relating to the size of respective objects is obtained with the aid of a camera scanning against a light source. At the correct moment in time, control signals are transmitted to finger groups, preferably four, which function to guide ten or more objects simultaneously in mutually different directions, in accordance with the respective sizes of the objects. In one embodiment, the lowest fingers are replaced with triangular-shaped guidance blocks. A large number of objects can be sorted gently and effectively from the transport path into mutually different, individually selective sizes.

  • Patent number: 5090574
    Abstract: Apparatus (1) for removing detected tramp material (TM) in a flow of material (M) moving along a primary flow path (P). The tramp material is deflected into one of two deflection paths (P1, P2) which are located of opposite sides of the material flow path. A scoop (29) is responsive to the detection of tramp material to deflect it into one of the deflection paths. The scoop is transported over rails (45, 47) between the deflection paths and across the primary flow path by a carriage (43) driven by a penumatic cylinder and rope and pulley unit (65). An actuator unit (91) repositions the scoop after each traversal of the flow path so it can deflect tramp material on its next traverse of the primary flow path.
