CONTROL DEVICE FOR EXTRUDER AND EXTRUDER APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce the work load of an operator and to stabilize production efficiency and quality. SOLUTION: When an operator inputs the new command value Qs of feed quantity Q or the new command value Ns of a rotational speed Ns from a keyboard 11, a control device for an extruder 10 calculates other new command value automatically to set an intermediate command value and controls feeders 1, 2 and an extruder 3 so as to achieve the intermediate command value by one stage to stepwise transfer the same to the new command values Qs, Nss. By this constitution, the work load of the operator can be reduced to a large extent. A work mistake becomes hard to generate and production efficiency or quality can be stabilized.
