  • Patent number: 7281361
    Abstract: A method for detecting and discriminating articles that are within a predetermined range of a specification into lots feeds a plurality of articles into an article portioning system having a counting head assembly that includes an article detecting unit located above and cooperatively controlling through generated signals an upper diverting gate and lower outlet gate which control the passage and/or accumulation of articles in adjacent channels to permit filling of article containers with predetermined article portions as containers are placed beneath, and removed from, the assembly outlet. The method for portioning discrete articles by feeding the articles and generating signals controlling the gates is suited for a combined plurality of such assemblies to provide high speed continuous container filling operations for simultaneous filling of groups of containers.

  • Patent number: 6836527
    Abstract: An improved method for counting irregular or unsymmetrical shaped articles that allows greater precision and provides enhanced features over current counting devices and methods. The method improves upon current devices and methods by providing a more precise volume for each article by using actual cross sectional areas of articles. The improved method also allows the user to count broken or incomplete articles as “partial” volumes. These partial volumes may be added to one another to give a precise total batch volume. The actual cross sectional areas may also be used to allow the user to display three dimensional adaptations of each article counted. Because this information is stored, the articles may be displayed at any time after the articles are scanned. The improved method also allows a user to determine the distance between articles, by using the counting device, and, using this information, adjust the feed rate of the device to an optimum feed rate.

  • 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: 6563901
    Abstract: A counter unit counts discrete articles that are within a predetermined size range into lots having a predetermined number of articles. The counter unit includes (1) a first conveyor that delivers a flow of articles separated at discrete intervals; and (2) at least one bin positioned to receive articles from the 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 detector unit detects and maintains a count of articles that are received in the at least one bin and fall within said predetermined size range. The detector unit generates an out-of-size signal when an article received in the at least one bin falls outside said predetermined size range. A control unit causes the first outlet gate to open when the count of articles is equal to said predetermined number and causes the second outlet gate to open in response to receipt of an out-of-size signal.

  • Patent number: 5804772
    Abstract: Apparatus and a method for aggregating a desired number of articles without individually counting out each article to achieve the desired number. A stream of the articles is discharged into a weigh hopper until substantially a predetermined weight of articles is in the hopper. The number of articles in the hopper is determined from the total weight of the hopper and the weight of a single article. Additional articles are caused to enter the hopper one-by-one until the desired total number of articles is contained in the hopper. The contents of the hopper are then packaged for distribution.
