Abstract
A spinning frame is connected to the winder through a delivery passage comprising conveyor belts, rotary disc and the like to form a closed loop. Cops are inserted independently on trays arranged on the delivery passage and are circulated along said closed loop in the state where they are vertically inserted. When the residual yarn-retaining bobbin is detected, the bobbin is re-circulated after required processes such as a pick finding operation.
Claims6
A cop delivery system for automatically delivering cops from a spinning frame to a winder and empty bobbins from the winder to the spinning frame, the winder having an entrance and an exit opening, the system comprising:
- a cop delivery conveyor connecting a spinning frame to a winder and forming a closed loop therebetween, said delivery conveyor including a discharge conveyor for moving empty bobbins to the spinning frame and a supply conveyor for moving cops to the winder;
- a plurality of trays, each having a cop carried independently thereon, said trays being arranged on the delivery conveyor to convey cops;
- pick finding means for performing a pick finding operation on each cop which is carried on a tray;
- transfer means for moving a tray carrying a cop into and out of a winding position in the winder;
- and
- detection means for (a) monitoring bobbins after the winding operation to detect any residual yarn-retaining bobbin and (b) delivering each bobbin to either the supply conveyor or the discharge conveyor as a function of the monitoring operation.
