Abstract

An automatic spool-changing system for textile machines with an array of high-speed winding heads, for example of the type having a spool revolver and a lossless thread transfer device. The system has a conveyor moving along the machine front and a spool changer with a gripper movable between the conveyor and a spool holder in a spool-changing position. The conveyor is located below and in generally the same vertical plane with the spool holder, and the gripper, which is arranged for both rotation and axial translation, is mounted for movement along a three-legged spool doffing and spool-donning path extending forwardly of the machine front. Two embodiments are shown. In the first, a separate empty-spool magazine is provided and the conveyor merely serves to carry away the empty spools. In the second, the conveyor serves for the transportation both of full spools and empty spools; in this case the gripper has two angularly displaced heads so that it can execute a spool-doffing and spool-donning operation simultaneously. Controls for the spool-changing system are also disclosed.
