Abstract

The conveyor systems are popular applications for continuously transporting objects in both industrial and agricultural sectors. For the current system used, the producers cannot inspect the objects inside the packages while being transported. In so doing, the transporting system has to be stopped for package weighing periodically. As a result, this system decreases the speed of transportation and wastes the sensor equipment. This article proposes a new investigation method that estimates the weight of an object being transported on the belt conveyor. When an object is being transported, its weight will affect the load torque of the motor. The load torque variable can be estimated by using observer and adaptive compensator. This variable is used in algorithmic verification which conduces to inspect objects inside the packages on the belt conveyor.
