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.

Bobbin sorting device

A supply yarn fitting device and a reserving section are provided in a supply section, and either the supply yarn fitting device is constituted such that it can fit supply yarns such as packages from a plurality of reserving locations or the reserving section is constituted as a supply yarn reserving device having a function of supplementing supply yarns to a reserving location in response to operation of the supply yarn fitting device so that supply yarns may be supplied automatically onto a transport passage in the yarn supply section.

Yarn supply device for automatic winder

A conveyor device for transporting a peg tray carrying a bobbin thereon without being inclined during the transportation thereof. In a conveyor device in which a belt is arranged upright with respect to the direction of width thereof and a peg tray carrying a bobbin thereon is mounted on the edge portion of the belts to be transported by the belt, two belts are provided and arranged in such a way that they are in parallel with each other and the peg tray is mounted on each of the edge portions of the two belts.

Conveyor device for transporting peg trays

According to the method of the present invention, when the package is supplied to the winder while being fitted on the tray, a yarn end released from the package is processed to be positioned at substantially central portion of one end face of the package from which the yarn is drawn, and then the package is fed at the predetermined winding position of the winder. The yarn end which is positioned at the central portion of the end face of the package may be wound around the extremity end of a peg of the tray or a head part of a take-up tube of the package by several times and the such processed package is fed to a rewinding step.

Method and apparatus for processing yarn end of package

A yarn end finding device for a spinning bobbin produced in a spinning frame. A bobbin rotating and driving device and a bobbin discriminating device are provided on a bobbin processing station in a yarn end finding device, and the rotating direction of the bobbin rotating and driving device is switched by a signal for detecting a kind of bobbins according to the discriminating device.

Yarn end finding device

A positive dobby in which a pair of cam plates for moving each heald frame positively vertically are provided separately on the first cam shaft and on the second cam shaft parallel to the first cam shaft, whereby the dobby is constituted without enlarging the pitch between the cam plates corresponding to each heald frame.

Positive dobby

A bobbin removing apparatus for an automatic winding system comprising a running belt and a bobbin guide member confronting with the belt, the apparatus being so constructed that a bobbin is tightly caught between the belt and the guide member and removed from a bobbin conveying medium by utilization of the motion of the belt.

Bobbin removing apparatus

A yarn end finding apparatus having a vertically movable hollow member which can be raised to allow positioning of a bobbin thereunder and then lowered onto the bobbin. The hollow member includes a device for releasing the end of the yarn from the bobbin. A vertical flow of air through the hollow member directs the released yarn away from the bobbin past a yarn clamping device and a blade which cuts the yarn at a predetermined distance from the clamping device. A reverse flow of air directs the remaining length of yarn into the hollow bobbin core for subsequent processing.

Yarn end finding apparatus

Improvements in a cop supplying apparatus comprising a cop supplying truck which runs along individual winding units of an automatic winding machine and feeds cops into magazines of the winding units without stopping. The cop supplying truck is provided with a guide and a pair of rollers for positively feeding the yarn end which is arranged under a long hole for placing cops through so that the yarn end of the cop held on a cop container is positively taken off from the cop container.
