A rotary bag-feeding machine with an external screw feeder shows no signal. Common causes are sensor faults, mechanical faults, electrical faults, program errors, and incorrect operation.
Sensor fault
Check whether the sensor is working. Clean the sensing area and reset the parameters.
Mechanical fault
Inspect the rotary bag feeder and screw feeder for mechanical problems. Clear jams and tighten loose parts.
Electrical fault
Check the electrical control system. This includes wiring connections, power supply, and the controller.
Program error
Check the program settings. Confirm the control logic and motion parameters match the machine setup.
Incorrect operation
Check that the operator follows the standard procedure. This covers material loading and machine start-up.
If replacement sensors, couplings, or screw feeder parts are needed, Hansheng Automation can machine them from customer drawings in single pieces or small batches.
