Title:
OPERATION CONTROL SYSTEM FOR PINNING MACHINE
Document Type and Number:
Japanese Patent JPH06127824
Kind Code:
A
Abstract:

PURPOSE: To operate a spinning machine always in the optimum operating state by measuring the operating state of the spinning machine, and at the time of the measured data being out of the set range, changing an operating condition so as to return the measured data into the set range.

CONSTITUTION: Yarn Y released from a yarn supply bobbin is wound onto a package through a variable tension device 14, a slab catcher 15, and the like. During this winding, the actual value data of a tension release factor is compared with the set value of a release factor setter 40 by a second comparing part 41. When an abnormal state out of a specified range is judged, a signal to the effect of changing the target value of the tension release factor is sent out to a third comparing part 42 from the second comparing part 41, and the changed target value is sent out to a reference input converting part 1 from the third comparing part 42. A changed reference input signal is then sent out to a first comparing part 2 from the reference input converting part 1, and a control action signal generated in the first comparing part 2 is sent to a yarn tension control part 4 to put the variable tension device 14 in action.
