Abstract
A continuously moving load is conveyed through a plurality of weighing load cell assemblies during a weighing operation to obtain a predetermined number of repetitive weight measurements fed to a data processor for providing an error corrected readout. Individual weight measurements are monitored to identify load cell assemblies from which erroneous readings are derived and to remove such erroneous readings from the data processing operation.
Claims18
In combination with a conveyor from which a plurality of load supporting shackles are suspended during continuous movement along a conveyor path, a system for weighing loads carried by the shackles during said movement thereof, comprising a predetermined number of load sensing devices, means mounting said load sensing devices at locations spaced along the conveyor path for successive loading by each of the loads carried on the shackles during said movement thereof, means connected to said load sensing devices for transmitting repetitive measurement data therefrom with respect to each of the loads, and data processing means connected to the data transmitting means for transforming the repetitive measurement data from the load sensing devices into an error corrected readout with respect to each of the loads.
In combination with a conveyor continuously moving a load along a predetermined path, a system for weighing said continuously moving load comprising, a plurality of load sensing devices spaced along said path for successive loading by said load during a weighing operation, signal transmitting means connected to the load sensing devices for receiving a plurality of repetitive inputs therefrom in response to said successive loading thereof by the load during the weighing operation and data processing means connected to the signal transmitting means for transforming the repetitive inputs received during said weighing operation into a weight measurement of the load.
In combination with a conveyor continuously moving spaced load carriers along a conveyor path and a plurality of load sensing devices engageable by the load carriers during said movement thereof for weighing loads supported thereon, a method of obtaining an accurate weight measurement for each of the loads, including the steps of:
- successively conveying each load carrier past a predetermined number of said load sensing devices along the conveyor path to obtain repetitive weight measurements therefrom during a single weighing operation;
- and averaging said repetitive weight measurements to obtain an error corrected weight measurement for said load upon completion of the weighing operation.
A method of accurately weighing a load continuously moving along a path, by means of load detecting devices from which weight measurements are obtained, including the steps of:
- conveying said moving load successively through said load detecting devices during a weighing operation to obtain a plurality of said weight measurements therefrom;
- applying a data processing operation to said weight measurements to produce a corrected weight readout;
- monitoring the respective weight measurements to detect excessive deviation thereof from the corrected weight readout;
- and removing the detected weight measurements from the data processing operation.
