摘要： A method for operating a weighing apparatus and system contemplates that the system is operated in a ratio of two modes of operation, including a first, non-sampling mode, and a second, sampling mode. Operating in the first mode, wherein verification of a dose weight is not effected, promotes high cycle rates. Operation in the second, sampling mode requires operation at a slower cycle rate, but permits optimization of the accuracy of the overall weighing process. Operation in the two modes of operation, and adjustment of the ratio of the modes of operation, promotes optimization of weighing accuracy and cycle speeds.

摘要： A method for controlling an amount of material delivered during a material transfer. This method includes the steps of inputting a target amount for a material to be delivered from a source location to a target location, updating the target amount during the delivery of the material using a predictive model-based algorithm, and updating the predictive model-based algorithm based on process performance data using a recursive least-squares procedure. An adaptive selection algorithm which is used to determine whether at least one previous predictive model-based algorithm parameter should be replaced with at least one new predictive model-based algorithm parameter in order to adapt the predictive model-based algorithm in response to a process change. A method for overlapping a delivery of at least one independently measured material with a delivery of a main material during a material transfer process.

摘要： Bulk materials are supplied on to a conveyor one after another with the supply port filled with the material. Since the pressure applied to the conveyor surface by the material is constant, what is called the fall error is eliminated. In one embodiment the conveyor is moved while in another embodiment the material is carried by scrapers secured to a chain conveyor.

摘要： A method for cyclically weighing flowable bulk solid material as part of a dispensing process which includes the steps of supplying the material from a continuously operating controllable delivery feed arrangement to a weigh-pan; generating a signal indicative of the amount of material in the weigh-pan; terminating supply of the material from the feed arrangement when the signal indicates a predetermined amount of material in the weigh-pan; causing the weigh-pan, after receiving and weighing all the materials supplied by the feed arrangement up to such termination of the supply, to deliver its contents; preparing the weigh-pan for the next cycle; predetermining a rate of delivery from the weigh-pan in accordance with the requirements of the dispensing process in terms of the average amount delivered per cycle in a cycling frequency; supplying from the feed arrangement material to the weigh-pan through a valve mechanism in which the material accumulates when the weigh-pan is not receiving material from the valve mechanism; and controlling the controllable feed arrangement to supply the materials substantially at the predetermined rate. An apparatus for performing the above-noted method is also disclosed.

摘要： Flowable food is fed by a vibrator unit to a weighing platform which is carried by a weighing support which moves downwardly as the food builds up on the platform, the weighing support and vibrator being temporarily stopped by stops at a location prior to a point corresponding to a preselected weight and thereafter being allowed to continue its weighing movement or discharge food therefrom as the case may be.
