Abstract: A bobbin sorting device including a color sensor for distinguishing trays on which different kinds of bobbins are conveyed, characterized in that a metal plate is attached to each tray having one of different colors, and a detector is provided near the color sensor for detecting the metal plate.

Abstract: In a tray conveyor for conveying trays carrying spinning bobbins and the like thereon, an elastic member of convex cross section is mounted on the opposite side of a surface of a conveyor belt for conveying trays vertically, extending in the direction of travel of the conveyor.

Abstract: A bobbin discharge apparatus having a device for detecting a remaining yarn of a bobbin. A non-contact type sensor such as a photo sensor for detecting the presence or absence of the remaining yarn on a bobbin is arranged on a carrier passage of bobbins, and the bobbin and the sensor are provided relatively movably.

Abstract: A method for winding a fixed length of yarn on a yarn-supply package in an apparatus connecting an automatic winder or an innovation spinning machine having a winder with a two-for-one twister. The method comprises dividing a single yarn-supply package transferred from a winder side to form a plurality of twist-yarn packages on the two-for-one twister side.

Abstract: A system of controlling the winding operation of an automatic winder which includes a yarn joining device and a yarn cutting device disposed along the yarn running passage between a package and a spinning bobbin, comprising steps of cutting the yarn in response to a full-package signal, executing a yarn joining operation, and providing a doffing signal to instruct the relevant mechanism to execute doffing operation.

Abstract: A take-up tube supply system for use in an automatic winder having a plurality of individual winding units arranged into several winding sections with each section taking up a different kind of yarn. The take-up tube supply system includes a plurality of tube supply stations disposed at the ends of each of the winding sections and a doffing truck which moves through each of the various winding sections. A plurality of take-up tube stockers are provided, each respectively associated with one of the respective winding sections. The stockers are adapted to be alternatingly detachable coupled to either the doffing truck or the associated tube supply stations.

Abstract: A paper tube supply apparatus to an automatic winder. A paper tube releasing apparatus comprises a paper tube releasing section, a paper tube stock section, and a magazine driver section. The magazine driving device of the present invention includes a paper tube detecting mechanism for detecting the presence of absence of a paper tube in a releasing position and a clutch mechanism for allowing a rotational driving of the magazine to supply paper tubes stored in the successive cylinder.
