Servo-controlled apparatus for filling containers |
摘要 |
An apparatus for filling containers includes a food product fill pump having a valve member and pump piston operated by respective cam drives. A servo-controlled drive motor drives the cams, whereby the speed of the pump operation can be controlled independently of an associated container conveyor. Significantly, the servo-control of the apparatus permits the pump piston of the food pump to be operated during its container-filling advancing stroke at a substantially constant speed, while the pumping cycle time is selectively varied by selectively varying the speed of the piston retraction stroke.
