Compared with ordinary motors, advantages of servo motors in auger filler are obvious, so many filling opportunities give priority to servo motors. The servo motor can control the speed and position accuracy very precisely, and can convert the voltage signal into torque and speed to drive the control object. In addition to being commonly used in manipulators and robots, servo motors are also widely used in filling machinery, including food and pharmaceutical filling machinery. When filling, the servo motor controls the screw to rotate and discharge, and the rotation angle of the screw determines the amount of each discharge, so as to accurately control the filling volume.
10 Advantages of Servo Motors in Auger Filler
1. Precise Control:
The servo motor controls the speed and position of the screw with high precision. Regardless of the type of material, the servo motor can precisely control the speed and position of the screw, and its accuracy can reach 0.001mm. And the spiral turns only when there is a control command and stops when there is no command. If there is a sudden power failure, it will stop immediately and will not continue to rotate due to inertia. This enables accurate measurement and distribution of products during the filling process.
2. Flexibility:
Servo motors can adjust parameters such as speed, torque, and direction of rotation. Whether for free-flowing or non-flowing materials, the servo motor can automatically adjust the parameters to accurately control the filling volume according to its weight. And its control and flexibility are more reliable, enabling the machine to handle various product types, sizes, and weights. Because of its high precision, it is suitable for filling food, cosmetics, daily chemicals, agriculture, and especially the pharmaceutical industry.
3. Repeatable Accuracy:
Servo motors provide excellent repeatability, ensuring consistent fill volumes with minimal variation. Servo motor control with repeatable accuracy is critical for filling biological products and food. The maximum allowable error of each filling is controlled within 1% or even lower, which can easily reach the national allowable maximum error range. This is critical to maintaining product quality and meeting regulatory standards.
4. Speed and Efficiency:
Servo motors can deliver high-speed and smooth operation. It only takes 200-400 milliseconds to accelerate from a standstill to a working speed. It can be used in control occasions that require fast start and stop. Now the output density of the servo motor has exceeded 1.2kW/kg, and the efficiency has reached 90%-97%, thus improving the productivity and throughput of the filling machine. In recent years, motors’ output density has increased by increasing the speed of small motors, using high-performance magnetic materials, and adopting high-efficiency cooling methods, which can also quickly respond to changes in filling requirements and optimize the overall efficiency of the process.
5. Quick changeover:
Using servo motor technology, switching between different products or fill volumes is easier. For different materials, whether it is solid, liquid, or paste, it can adjust the filling stroke at any time; at the same time, the filling method is also compatible with various bottle types and can be switched between different filling volumes. Programmability allows quick adjustments without mechanical changes, reducing downtime when changing lines.
6. Error Detection and Correction:
Servo motors can incorporate feedback mechanisms such as encoders or sensors to monitor the filling process in real time. This enables the machine to detect errors or inconsistencies and make immediate corrections, ensuring accurate filling. This is an indispensable existence in the modern pharmaceutical industry. If the filling of medicines is not properly controlled, it is easy to cause excessive losses and affect the quality of medicines. However, servo motors can precisely control the filling of medicines, thus effectively solving these problems.
7. Energy Efficiency:
Servo motors are designed to consume energy only when needed. It adopts frequency conversion speed regulation, electromagnetic braking is used when decelerating, the braking energy can be stored and recovered, and it can also reduce the power consumption during idle or low load, so it has not only high efficiency but also has low loss, thus saving energy and reducing costs.
8. Durability and Reliability:
Servo motors are designed to withstand harsh industrial environments. It uses high-quality materials and components, has good anti-seismic, anti-vibration, and anti-interference capabilities, and can adapt to harsh working environments. And it’s also known for its robust construction, long service life, and minimal maintenance requirements, making it a solid choice for auger fillers.
9. Integration with control systems:
Servo motors can be easily integrated into advanced control systems, enabling seamless communication and coordination with other machine components. It can receive control commands from other machine components, which enhances its automation and data acquisition capabilities. At the same time, it is very easy to use, greatly improves the system’s performance, and saves users a lot of time.
10. Safety Features:
Servo motors have multiple safety guarantees. The servo motor has a built-in overheat protection device. When the temperature of the servo motor is too high, it has an overheat protection function to prevent equipment failure; when the power supply is suddenly interrupted, the servo motor can activate the power-off protection device; when the rated load is exceeded, the servo motor activates overload protection The device prevents equipment damage; when the position deviates, the servo motor turns on the built-in position protection device. These features help prevent damage to the machine, protect the operator, and ensure overall operating safety.
Conclusion
Nowadays, servo motors are widely used in filling machines, including food and pharmaceutical filling machines. The correct use of servo motors can promote the development of many industries. It is hoped that servo motors can be used in more industries to continuously promote economic development.
