Title: Ring spinner or twister spindle speed control - has monitors at specific spindles with control to apply corrections to all the spindles
Inventor: ANDEREGG PETER
IPC: D01H1/34
Filed: 1992-04-07
Abstract: To control the speeds of the spindles in a ring spinning or twisting machine, measurement values (2a,2b) are taken from specific spindles (12) in the assembly. The values are taken to modify a spindle rotary speed program (5) so that the measured values can be aligned at least generally with set nominal values. Also claimed is an appts. with sensors (13,14) at nominated spindles (12). The control units (1) passes setting values for the rotary speed program (5) not only to the drives (10) of the spindles (12) used for measurement, but also to the drives (10) of adjacent spindles (11). One measured value (2a) is either the frequency of the yarn (7) winder and/or harmonic of this frequency, or a frequency band for the yarn noise. The frequencies are filtered out of a sensor signal and the level is measured of the frequency, frequencies or frequency band. One measured value (2b) is the operating temp. of the test spindle (12). The yarn tension monitor registers the yarn tension, and transmits tension values to the control (1). USE/ADVANTAGE - The system is for the operation of a ring spinner or twister, with control to set the required spindle rotary speeds. The monitoring and measurement system is simpler, and incurs a lower installation coat, while capturing the actual performance rate and applying any necessary corrections.
