INVT PLC HMI Servo System Applied for Auger Filler in India

Abstract: India people consume lots of small pack food, snacks, spices, tobacco, and flavor every day. The packing industry is very strong. Auger filler machine is a basic machine for powder packing. This paper mainly introduced auger filler machine control systems, and INVT products.

Keywords: INVT, PLC HMI Servo, Auger Filler

1.Application introduction

In Auger filler machine, one VFD is used on paper pulling and length is set by the on time timer, after that vertical sealing, horizontal sealing, coding, printing, nitrogen and batch cutter is run and controlled by the on delay time and on time timer. Filling is done with the help of servo and calibration of servo is done with the help of PLC and HMI by manually for one rotation after that they set the gram in one rotation.

For eye-mark they used sensor and for corrections they use on time for the same. There is a batch cutter to cut the product in a no of batch set in the HMI. Un-winder is used to unwind the paper so that paper is run smooth and cut on eye-mark.

3.5 System advantages
Attractive HMI graphics designs

PLC timer design to calibrate the signals:

After apply INVT solution, production efficiency and accuracy improved, it’s more user friendly and easy to maintain.
High speed, high efficiency, powder filling at 25 bags per minutes at 1 kg.
Weight calibration function, can done by customer itself
High accuracy, weight variation is very small approx. +/- 1%.

4.Conclusion

INVT PLC, HMI, Servo and vfd drive solution is successfully used for auger filler which is the basic and popular packing machine. It improves the production efficiency and accuracy, and user friendly design, simplifies the maintenance. It’s worth to promote all over India.
