The present invention deals with a filling device (1) and a weighing device, wherein at least one 3D sensor (2) is provided to capture at least a partial area of the transport surface, virtually dividing the detected area into a plurality of sectors (3) and zones (4). The at least one sensor (2) is adapted to determine a distance to the measuring point as well as a respective angle of incidence at which the measuring point of the detected surface is measured, The filling device (1) is adapted to make a division into sectors (3) and zones (4) dynamically as a function of at least one influencing variable (E) to derive relevant information for the regulation of the control parameters therefrom in order to achieve a controlled product distribution.

Systems and methods for control of the delivery of contaminates are provided. A conveyor moves contaminate particles from a hopper into an airflow. The contents of a hopper at multiple time points within a sliding window of time are weighted with a scale. A processor applies linear regression to a data set comprising the time points as an independent variable and the weight measurements as a dependent variable, resulting in a determination of a line fitting the data set. A processor determines a current mass flow rate of the contaminate particles from the slope of the line. The processor determines an estimated change in the conveyor motor speed needed to achieve the target mass flow rate, the estimated change determined from a predetermined mapping of flow rates to motor speeds, the estimated change based on the current mass flow rate, the target mass flow rate, and a predetermined fraction.

An article inspection apparatus includes a measuring unit 11 that outputs a measuring signal of weight within a required measurement time from a weight application time, when the weight of an article W is applied, a determination unit 16 that inspects the article W based on the measuring signal, an electromagnetic coil 84 that applies a diagnostic load to the measuring unit 11, and a performance diagnosis unit 18 that causes the diagnostic load to be applied from the electromagnetic coil 84 to the measuring unit 11, within a predetermined diagnosable time longer than the required measurement time from the weight application time, when the weight of the article W is applied to the measuring unit 11, and diagnoses the performance of the measuring unit 11, based on the measuring signal when the diagnostic load is applied.

Method for weighing an object transported on a mover of an electromagnetic conveyor and electromagnetic conveyor. Method includes lifting object off the mover with a lifting device; setting down object onto at least one transport plane of a weighing station arranged at a weighing region of the track and arranged on at least one weigh cell. The transport plane extends in the direction of movement to support the object when in the weighing station. The method also includes actively driving object while lifted off from the mover and while supported on the transport plane with the mover as it moves along the track through a weighing region; weighing object with at least one weigh cell while the object is supported by the transport plane; and setting down object on the mover after weighing in the weighing station for onward movement of object along the track with the mover.

A method and a system measure interfering influences on a checkweighing device. In the method, external interference data are obtained, as are interference data from the checkweighing device itself and interference data from an object being weighed, by calculating or mapping the weighing error data in the stationary state, in the operating state, and in the weighing state. The system for measuring the interference uses a meter and a processing apparatus. The meter and the processing apparatus perform an interference measurement and a compensation method. The amount of interference in the checkweighing device in each state and the amount of influence of the interference on the weighing performance is obtained, thereby facilitating the production, debugging, maintenance, and use of a checkweighing device.
