Technical Systems approached HmT Mechatronics to assist them in the re-design and retrofit of one of their five auger machines. Although mechanically the machine was still in a good condition, the electrical control system’s lifetime has come to an end and needed to be replaced with a more advanced and accurate control system.
Raw material from a bobbin is fed into the auger machine by a series of SEW gearboxes connected via belt drives onto a 15kW AC motor. This motor’s speed and torque is controlled by an equivalent Yaskawa VSD. The head motor (also Yaskawa) allows the operator to change the produced auger’s pitch and diameter by the forward and backwards movement of it. The produced product is then fed into a pipe system containing two sensors calculating the ratio between the raw material used and product produced. The system caters for; recipe selection, alarm list, user setup, total production and service intervals.
