Common Faults and Cause Analysis of Automatic Checkweighers in the Application Process

Issue Time:2022/01/11
he common faults of checkweighers in operation and the corresponding reasons,
If there are some abnormalities in the use of the automatic checkweigher, it means that there are some faults in the equipment itself. At this time, in order to ensure the normal operation of the production line, we need to analyze the reasons in time and carry out the targeted treatment. In order to help you find the fault point more quickly, Syndar has sorted out the following common faults and the corresponding reasons for you.

The automatic checkweigher is powered on, and the flashing screen does not flash when touched

(1) Check whether the power supply is normal, and check whether the power switch is damaged;

(2) Whether the leakage switch in the electric box has tripped;

(3) Check whether the switching power supply itself is damaged;

(4) Check whether the 24V circuit is short-circuited and whether the fuse is burned out;

(5) Whether there is a quality problem with the splash screen itself.

All three belts of the conveyor line do not roll

(1) Check whether the 24V voltage output by the switching power supply is normal;

(2) Check whether the communication between the splash screen and the PLC is normal (there is a "PLC-IO port" option in the "System Fault" of the "Main Menu" of the splash screen, you can check whether the communication is faulty).

The belt of the conveyor line does not work in a single section

(1) Check whether the synchronization belt is stuck or damaged;

(2) Check that the conveyor belt is not jammed by foreign objects;

(3) Check whether the connecting terminal of the motor is loose or dropped;

(4) Select the replacement method, and adjust the motor drive and the motor to see if it is a driver problem or a motor failure.

Automatic checkweigher cannot eliminate substandard products

(1) If the rejection is not in place, check whether the system's removal output delay and removal hold time are set accurately;

(2) Check whether the air pressure of the air compressor is normal, and check the pressure gauge;

(3) Check whether the solenoid valve is faulty, check the solenoid valve by hand to see if there is any response;

(4) Check whether the cylinder is malfunctioning;

(5) Check whether the solid-state relay response is normal;

(6) Check whether the IO controller part of the automatic checkweigher is burned out.

Automatic checkweigher results are not accurate

(1) Check whether the parameter setting has been artificially changed;

(2) Whether the vibration of the workshop environment is relatively large or the airflow is large;

(3) Whether the feeding distance is the same as the original one;

(4) Whether the weighing platform is clean and whether there is foreign matter sticking to it;

(5) Whether the weighing platform conveyor belt and the other two conveyor belts are touching;

(6) Whether the screw maintained by the sensor touches the edge of the weighing platform;

(7) Whether the sensor has been damaged or deformed by man-made heavy pressure;

(8) Whether the sensor wire and motor wire are loose or pulled too tightly;

(9) Whether the position of the photoelectric switch is adjusted accurately (especially when the measured object is a special-shaped part).

The conveyor belt is off track and cannot be adjusted

(1) The belt has been used for too long, and the wear is severe, deformed, and elongated, consider replacing the belt;

(2) The roller has been used for a long time, and the wear is severe. Consider replacing the new roller.
