What should be done if the weighing of the sorting scale is unstable?

What should we do if the Sorting scale has unstable weighing? The weather is getting colder and colder. First of all, I remind all friends to pay attention to keeping warm. Secondly, recently, some units using Sorting scales have called to consult about what to do if the weighing of the sorting scale is unstable. The editor took time to summarize for everyone how to deal with it:

1. Levelness check

The sorting scale must be installed on a horizontal ground. Otherwise, the weighing accuracy will be affected. Use a spirit level to check the levelness of the equipment. If it is found to be not level, adjust the anchor bolts of the equipment to make it reach a horizontal state.

Ensure that the equipment is firmly installed without shaking or loosening. Check whether all parts of the equipment are tightly connected. If there is looseness, tighten it in time.

2. Environmental factors

Avoid installing the sorting scale in places with vibration, electromagnetic interference or large temperature changes. These factors will affect the performance of the weighing sensor and lead to unstable weighing.

If the influence of environmental factors cannot be avoided, some measures can be taken to reduce its influence, such as installing shock absorbers and shielding electromagnetic interference.

3. Sensor failure

The weighing sensor is the core component of the sorting scale. If the sensor fails, it will directly lead to unstable weighing. Check whether the appearance of the sensor is damaged or deformed. If there is a problem, a new sensor needs to be replaced.

Use tools such as a multimeter to check whether the output signal of the sensor is normal. If the signal is abnormal, there may be a problem with the internal circuit of the sensor and it needs to be repaired or replaced.

4. Sensor installation

Ensure that the weighing sensor is installed correctly without loosening or shifting. Check whether the installation position of the sensor meets the design requirements of the equipment. If necessary, the sensor can be reinstalled.

The connection line of the sensor also needs to be checked to ensure that the line is firmly connected without short circuit or open circuit.

5. Software settings

Check whether the software settings of the control system of the sorting scale are correct. For example, check whether the settings such as weighing parameters, sorting range, and alarm threshold meet actual needs.

If the software settings are incorrect, it may lead to unstable weighing or misjudgment. Adjust the software settings according to the actual situation to ensure the normal operation of the equipment.

6. Hardware failure

Hardware failures in the control system may also lead to unstable weighing. Check whether hardware devices such as controllers, displays, and keyboards are working properly. If there is a problem, it needs to be repaired or replaced.

Ensure that the power supply of the control system is stable without voltage fluctuations or interference. A stabilized power supply or filter can be used to improve the stability of the power supply.

7. Clean the equipment

Regularly clean all parts of the sorting scale, especially the weighing sensor and conveyor belt. Impurities such as dust and dirt will affect the performance of the sensor and lead to unstable weighing.

Wipe the equipment with a clean damp cloth or cleaner. Be careful not to let water or cleaner enter the equipment.

8. Maintenance

Perform regular maintenance according to the equipment's operation manual, such as replacing worn parts and adding lubricating oil.

Calibrate and debug the equipment to ensure the accuracy and stability of weighing. A standard weight can be used for calibration, or a professional technician can be invited for debugging.

When the sorting scale has unstable weighing, we should take timely measures to check and solve the problem. By checking equipment installation, weighing sensors, control systems, and performing cleaning and maintenance methods, the weighing stability of the sorting scale can be effectively improved to ensure the smooth progress of production.
