Abstract: A method for weighing sliced products to generate product batches of a pre-determined weight. A slicer slices products which are disposed onto a slice scale located beneath the output end of the slicer. An intermediate weight is measured at a pre-determined point in the slicing process. The intermediate weight information is used to calculate the minimum number of completion slices, based on thicknesses of the slices, needed to meet the target weight. The competed draft is transferred to a check sale where a final draft weight is measured and compared to a sum of the intermediate weight and the weight of the completion slices. Comparison of the weight is used to adjust slicing parameters for more precise targeting of the desired weight of the next draft. Completion slices may be adjusted in thickness to minimize the giveaway weight.

Abstract: The accuracy of the output feed rate or output feed quantity of a differential dosing scale is increased by eliminating from the respective feed rate signal or output quantity signal measuring disturbance that can adversely influence the output accuracy. For this purpose, the size of the output signal variations or of the feed rate variations are processed in a fuzzy logic circuit (9) which allocates the respective signals to fuzzy sets, e.g. "small", "medium", "large" in accordance with type and size of the disturbance or interference. The fuzzy logic circuit (9) forms a filter control signal that corresponds to a filtering degree or filter factor. The filtering control signal controls the time constant of a time variable filter (6) through which the differentiated signal coming from the dosing scale load cells is passed prior to processing in the fuzzy logic circuit (9).

Abstract: The precision of a closed loop control system, for example of a loss-in-weight feeder, having a controlled operating section and a closed loop controlling section, is improved by adjusting the closed loop controlling section with regard to at least two stochastic precision disturbing signals. One such signal may represent disturbances that affect a sensor for ascertaining the actual weight of the scale. The other value may represent estimated bulk material density variations or disturbances. A model generator (7) provides spectra representing these disturbing values. A noise parameter estimator (17) selects those spectra most closely resembling the spectra of the disturbing values for producing an adjusting signal that is used to adapt the closed loop controlling section (5) to an optimal control. The closed loop controlling section (5) has connected thereto an evaluating circuit (14) including the model generator (7) for performing the correction or adjustment.
