Title: Changing supply bobbins on spinning machine - has detector sensing quantity of yarn remaining to predict change over time, for improving efficiency of manual or automatic piecing
Inventor: CITTERIO GIORGIO
IPC: D01H9/00
Filed: 1991-12-16
Abstract: Changeover time of supply bobbins, esp. on a spinning machine, is predicted by using the take-off rate to calculate the elapsed time since the previous changeover. The take-off rate is pref. measured against the amt. of material left on the bobbin and the rate of processing. Appropriate signals can be provided for operators or automatic piecing robots. Reflectors (10a,10b) are pref. mounted above the supply bobbins (2,3) and optical sensors (13,14) monitor the reflected light beam (15). The reflector (10a) is smaller in dia. than the full bobbin so that the signal is interrupted when the bobbin is loaded. The beam is only detected when the bobbin has been unwound to the smaller dia. (d). The time when a bobnbin change will be required can be calculated from the feed rate at the feed roller and the quantity of feed yarn left on the supply bobbin. USE/ADVANTAGE - The invention provides advance warning of supply bobbins running out and improves efficiency of manual or automatic piecing.
