Check weigher is a kind of non-standard customized equipment, which is the dynamic detection of product weight on the production line. According to the weight of the product, detection accuracy, per minute detection speed for customized check weigher, can quickly reject the unqualified products. Next is the introduction of the common failures and precautions for the use of check weighers.
Here is the content list:
l Common faults
l Precautions for use
There are many common failures of check weighers, and the next is to introduce you to the direction of inspection of these three failures.
The weighing machine shows that the detected products are not qualified, but the rejecting device does not reject or rejects not in place
If the reject is not in place, check whether the reject output delay and reject hold time of the system are set accurately. Check whether the air pressure of the compressor is normal, check the pressure gauge. Test the cylinder for failure and the solenoid valve for failure. Test the solenoid valve by hand to see if there is any response. Check whether the IO controller part of the check weigher is burnt out. Test if the solid-state relay reacts normally.
The belt of the conveyor line does not run in a single section
Check whether the synchronous belt is stuck or damaged. Check whether the conveyor belt is stuck by foreign objects. Check whether the connection terminal of the check weigher's motor is loose or off. Use the replacement method to adjust the motor drive and motor to see if it is a drive problem or motor failure.
Check weigher suddenly appears inaccurate, or deviate from the target value is large
Check whether the parameter settings have been artificially changed. Whether the workshop environment vibration is relatively large or airflow is great, and whether the spacing of incoming materials is as even as the original. Whether the position of the photoelectric switch is adjusted accurately (especially when the object to be measured is a shaped piece). Whether the scale platform of the check weigher is clean, whether foreign objects are sticking to it, whether the conveyor belt and the other two conveyor belts are touching. Whether the sensor wire and motor wire are loose or pulled too tight. Whether the sensor protection screw touches the edge of the check weigher platform, whether there is no artificial heavy pressure damage deformation.
Work before opening the check weigher should check whether the belt is in good condition, whether there are problems should be replaced in time. Before weighing, turn on the machine to set various parameters and ask for sorting. If the equipment does not show the weight during operation, it may be light in height and the height of the photoelectric sensor should be adjusted. Make sure the check weigher is stable during operation, if it is not smooth, it may lead to data deviation. If the check weighing process is light in quantity can be solved by compensating the quantity. Keep a certain distance between the production line equipment to avoid mutual influence.
Foshan High-Tech Machinery Equipment Co., Ltd reminds you that when the check weigher breaks down, don't panic, you can check yourself by the above ways.
