MEAT EMULSION PUMP CONTROL SYSTEM FOR MEAT ENCASING MACHINE AND METHOD OF USE THEREOF

摘要

A meat encasing machine has a looper horn (12), linking chain (24) and conveyor (14) which, prior to production, have home positions which are determined. A pulsed signal is generated as the looper horn (12) rotates and is transmitted to an amplifier (36) from an encoder (34) on the servo motor (32) for the looper horn (12) and the conveyor (14). The output pulse signal is then reduced in frequency so that it can be read by a PLC (40). The PLC (40) counts the pulses in the signal and can determine the relative position of the looper horn (12) based on the count and can therefore minimize the rotation of the looper horn (12) in the home position at the beginning of each new cycle. The meat encasing machine may also be controlled such that the linking chain (24), looper (12), and conveyor (14) have no direct mechanical or electrical interaction between each other. By driving the components with separate servo motors (26, 32), each can be precisely controlled in the desired ratios with respect to each other.
