A plant for conveying material for the production of structural concrete comprises a first container configured to contain a first amount of material, a first detection member configured to detect a variation in the first amount of material and first release members configured to enable and/or disable release of the first amount of material towards a mixing area of the first amount of material. The plant further comprises a second container configured to contain a second amount of material varying between a second minimum and a second maximum reference amount, a second detection member configured to detect a variation in the second amount of material and second release members configured to enable and/or disable release of the second amount of material towards a mixing area. In particular, an unloading opening of the second container is connected to the mixing area, whereas an unloading opening of the first container is connected to a loading opening of the second container or to a mixing area. A control unit is configured at least to enable said release members to release the first amount of material when the second detection member detects the reaching of the second minimum reference amount in the second container. The present invention also relates to a process for conveying material for the production of structural concrete.

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).

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.

A sensor assembly for determining yield of grain harvested by a harvesting machine during harvesting operations. The sensor assembly includes a sensor housing, a displaceable sensor member and a displacement sensor. The sensor housing is mounted to the grain elevator housing above an upper sprocket of a conveyor disposed within the grain elevator housing. The sensor member is displaceably supported via the sensor housing within the elevator housing above the upper sprocket and along a direction of travel of the grain piles thrown by the conveyor flights rotating around the upper sprocket. The thrown grain piles produce a grain force on the sensor member causing a displacement of the sensor member in relation to the grain force. The displacement sensor generates a grain force signal corresponding to the displacement of the sensor member.

The system includes a scale and a plurality of sensors that work together to automate numerous functions that are typically performed manually. For example, the present invention discloses a system that automatically records the amount of material loaded or unloaded by continuously monitoring the load on a scale and the RPMs of a power take-off shaft that drives a conveyor.

In a method and apparatus for length measurement of a flat good in a goods processing system having first and second stations, each having a sensor in the transport direction of the flat good, a control processor implements a path control and counts encoder pulses of an encoder in the first station. An event is determined by the sensor of the second station, and an associated numerical value Z1 of the encoder pulses is stored in the control processor, as is a numerical value Z2 for a distance between the two sensors is also stored. An additional event is determined by the sensor of the first station, and an associated numerical value Z3 of the encoder pulses is stored. As soon as both events are present, Z2 and the difference Δ=Z3−Z1 are added by the control processor, and the sum is used to designate the length.
