Summary of common problems of automatic grading scale, how to deal with problems with automatic grading scale
Automatic grading scales are also called high-efficiency intelligent grading scales, automatic checkweighing scales, automatic sorting scales, etc., which are used for non-sticky granular materials. The equipment has standard communication interfaces and multiple recording functions, printing real-time reports and multiple recording. It can output data information reports such as shift production, daily production, monthly production, etc., which is easy to operate. Nowadays, the use of automatic grading scales in production workshops has become very popular, so what are the common problems of automatic grading scales? How should we deal with these problems? Let's take a look! Summary of common faults of automatic grading scale: When the automatic grading scale is powered on, the touch screen does not display. Solution: 1. Check whether the power supply is normal, and see if the power switch is damaged. 2. Whether the leakage switch in the electric box has tripped 3 4. Check whether the switching power supply itself is damaged. 4. Check whether the 24V circuit is short-circuited and whether the fuse has been burned. 5. Whether the touch screen has a quality problem. The three belts of the conveyor line do not rotate. Solution: 1. Test the output of the switching power supply 2. Check whether the communication between the display screen and the PLC is normal (there is a PLC-IO port option in the system failure of the main menu of the display screen, which is to test the communication between the display screen and the PLC. You can check whether the communication is faulty.) The belt of the conveyor line does not run in a single section. Solutions: 1. Check that the synchronization belt is not jammed or damaged. 2. Check that the conveyor belt is not jammed by foreign objects. 3. Check that the connection terminals of the motor are there. There is no looseness or falling off 4. Use the replacement method to reverse the motor drive and the 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. Reject If it 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 compressor pressure is normal. Check the pressure gauge. 3. Check whether the solenoid valve is faulty. Test the solenoid valve by hand to see if there is any response. 4. Check whether the cylinder is malfunctioning. 5. Test whether the solid state relay responds normally. 6. Check whether the IO controller part of the automatic grading scale is burnt. The automatic grading scale suddenly appears inaccurate or deviates from the target value. Solution: 1. Check the parameters Whether the setting has been changed manually. 2. Whether the workshop environment is vibrated or the air flow is large. 3. Whether the distance between incoming materials is the same as the original. 4. Whether the weighing platform is clean and whether foreign matter is stuck. 5. The weighing platform conveyor belt and the other two Whether the conveyor belt is touching 6. Whether the screw protected by the sensor touches the edge of the weighing platform 7. Whether the sensor is damaged or deformed by artificial pressure 8. Whether the sensor wire and the motor wire are loose or pulled too tightly 9. Whether the position of the photoelectric switch is adjusted Accurate (especially when the measured object is a special-shaped part) The conveyor belt is off-track and cannot be adjusted. Solutions: 1. The belt has been used for too long, and the wear is severely deformed and elongated. Consider replacing the belt; 2. The roller has been used for a long time and is worn Seriously, consider replacing the roller with a new one.
