Method for Troubleshooting Minor Faults of Automatic Weighing Machine

Aug. 24, 2020

Checkweigher equipment does not transport a large number of products and objects intermittently every day, and it runs non-stop for several hours. It is inevitable that there will always be some small failures during use. The the X-ray inspection system manufacturer summarizes some targeted troubleshooting methods for the minor faults that occur in the online weight inspection opportunities for reference by the majority of users.

1. The zero point is too high

Solution: It is necessary to regularly maintain the online weight detection system and clean up the zero adjustment operation.

2. Large measurement error

Solution: Check whether the solid structure of the assembly line weighing equipment is firmly installed, correct the position of the conveyor belt, measure whether the distance of the weighing bridge is appropriate, whether the instantaneous flow is normal, etc.

3. Load without cumulative value

Solution: Clean up the dust in the material box on the conveyor belt scale body and keep the surface of the weighing conveyor belt clean.

4. The instantaneous flow fluctuates greatly

Solution: Align the conveyor belt with the center line of the pallet.

5. Poor repeatability during calibration

Solution: If the speed signal of the online weight detector is abnormal, it indicates that the weighing signal is unstable. Check whether the load cell terminal is in good contact.

6. The output value fluctuates frequently

Solution: Need to align the belt with the center line of the pallet, and then re-calibrate.

In addition, do the following two things regularly:

First, level correction

Check whether the horizontal position of the scale body of the online weight detector is balanced. If the position is tilted, please adjust the feet of the scale so that the blisters are in the center position.

Second, clean the scale body

The specific method is to cut off the power supply and unplug the power cord. Soak the gauze and wring it dry, then dip a little neutral cleaning liquid, and use it to clean the weight sorting scale tray, display filter and the surface part of the sorting scale body.
