There are two different versions of Auger Filler: A/C Motor with clutch / brake system and D/C Servomotor. In both cases the fill dose is pre-set in a counter of the touch screen. When using a clutch / brake unit the count is made by the impulses of a transductor through a fast count input of the PLC. This system is more economic but it needs periodic maintenance in the clutch / brake and it is not possible to adjust the speed of the screw. Accuracy is around +/- 1'5 % for most products. When using a servo-motor, the accuracy and the stop position is always exact, (with no inertias). This system does not require any maintenance and permits to adjust the speed and the acceleration / deacceleration curves of the screw. The link with the PLC is made through a port of communication RS 485.Accuracy is around +/- 1 % for most products. The auger fillers are available in simplex, duplex, triplex or quadruplex versions. |
