Automatic grading scale, also known as high-efficiency intelligent grading scale, automatic multihead weigher, automatic multihead weigher, etc., is used for non-sticky granular materials. The equipment has standard communication interface and various recording functions, printing real-time reports and various records. It can output data information reports such as shift production, daily production, monthly production, etc., which is easy to operate. The use of automatic grading scales has become very popular in production workshops now, so what are the common problems of automatic grading scales? How do we deal with these problems? Let's take a look below! Summary of common faults of automatic grading scales: When the automatic grading scale is powered on, the touch screen does not display Solutions: 1. Check whether the power supply is normal and see if the switch of the power supply 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 the touch screen itself has quality problems. The three belts of the conveyor line do not rotate. 2. Check whether the communication between the display screen and the PLC is normal (in the display screen“main menu”of“system error”there is a“PLC-IO port”Option, it tests the communication between the display screen and the PLC, and can check whether the communication is faulty) The belt of the conveyor line does not run in a single segment Solution: 1. Check that the synchronous belt is not stuck or damaged 2. Check The conveyor belt is not stuck by foreign objects. 3. Check whether the connection terminals of the motor are loose or fall off. 4. Use the replacement method to switch the motor drive and motor to see if it is a drive problem or a motor failure. The automatic grading scale shows that the detected product is unqualified , but the rejection device does not reject or the rejection is not in place Solution: 1. The rejection is not in place, check whether the rejection output delay and rejection holding time of the system are set accurately 2. Check whether the air pressure of the air compressor is normal, check the pressure gauge 3. Check the electromagnetic Whether the valve is faulty, test the solenoid valve by hand to see if there is any response 4. Check whether the cylinder is faulty 5. Test whether the solid state relay response is normal Inaccurate or large deviation from the target value Solution: 1. Check whether the parameter settings have been artificially changed 2. Whether the workshop environment is relatively vibrated or the airflow is large 3. Whether the spacing of incoming materials is the same as the original 4. Whether the weighing platform Clean, whether there are foreign objects stuck 5. Whether the conveyor belt of the weighing platform and the other two conveyor belts are touching 6. Whether the screw protected by the sensor touches the edge of the weighing platform 7. Whether the sensor is damaged and deformed by artificial pressure 8. The sensor wire and Whether the motor wire is loose or pulled too tight 9. Whether the position of the photoelectric switch is adjusted accurately (especially when the object to be measured is a special-shaped part), the conveyor belt is deviated and cannot be adjusted. Elongate, consider replacing the belt; 2. The roller has been used for a long time and is seriously worn, and consider replacing the new roller.
The above is a summary of the common problems of automatic grading scales brought by Zhongshan Smart weigh for everyone, and related articles on how to deal with problems with automatic grading scales. I hope it will be helpful to everyone.
