Abstract: An unwinding assisting device for an automatic winder. The automatic winder has a winding position at which a cop of yarn is unwound from a take-up tube supported on a tray. A lifting mechanism raises the tray at the winding position as the cop of yarn is unwound from the take-up tube. A tubular member receives the take-up tube therein. The tubular member has an inside diameter that is smaller than the outside diameter of the cop and larger than the outside diameter of the take-up tube.

Abstract: A conveyor system for carrying various kinds of bobbins which can easily and reliably discriminate a wrong combination of a tray with a specific mark and a color bobbin of specific color, wherein a spinning bobbin wound on a color bobbin of specific color is inserted on a tray having a specific mark; the tray having the specific mark is selected by a tray selector from a main conveyor line on which two or more kinds of trays are transported together, being distributed to delivery lines and of specific winding unit groups. In the delivery lines, color sensors are mounted for discriminating color bobbins of specific color.

A indicia is formed in either the carrying medium or the guide member at the side of the conveying passage and a device for discriminating or detecting the discrimination indicia is disposed at a position to corresponding to the indicia.

Abstract: A bobbin transfer system consisting of a pair of conveyors, one to carry the spinning bobbins and the other to carry the empty bobbins, each installed at a top portion of a spinning machine to run along the spindle row. The spinning machine and a winder may be connected with each other by the conveyors.

Abstract: A yarn kind changing process for a spinning winder which comprises the steps of stopping winding of a bobbin being wound on a spinning spindle after a yarn kind changing instruction, cutting a sliver which extends between a draft part of a spinnig frame and a yarn supply station and joining a supply side sliver of a different kind to the sliver remaining on the draft part, starting the spindle again to wind yarn of the new kind on a layer of the yarn of the preceding kind on a winding bobbin, and removing the yarn of the new kind wound on the yarn of the preceding kind before the fully wound bobbin doffed from the spindle is subsequently supplied to a winder.

Abstract: In an automatic winder comprising plural winding units, a preset yarn quantity per lot and a residual quantity of yarn to be taken up are grasped upon generation of a full-loaded signal, then the number of operating winding units is decreased gradually, allowing operation of only winding unit or units of a number corresponding to the residual quantity of yarn to be taken up.

Abstract: A bobbin conveying system comprising a spinning frame, a winder and a bobbin conveyance line which interconnects the spinning frame and the winder and is laid above bases of the machines.A bobbin is independently erected on a tray and carried on the conveyance line and a transfer device for lifting or lowering the bobbin is disposed in a bobbin transfer position between the spinning frame and the conveying line and also in a bobbin transfer position between the winder and the conveying line.

Abstract: A device for sorting and transporting a plurality of different kinds of articles comprises three belt conveyors disposed in adjacent parallel relationship to each other, two of the belt conveyors moving in a direction opposite to each other, guide members for dividing transporting faces of the two oppositely moving belt conveyors into some areas, and a sorting device for identifying and sorting articles transported on the belt conveyor to the respective areas.

Abstract: A cop selecting and conveying apparatus for an automatic winder is disclosed in which winding units are divided into a plurality of winding sections and different kinds of cops carried on carrying mediums are transferred on the conveying passage to each winding sections. A discrimination indicator is formed in either the carrying medium or the guide member at the side of the conveying passage and a device for discriminating or detecting the discrimination indicator is disposed at a position to corresponding to the indicator.

Abstract: A cop supplying system for an automatic winder in which a plurality of cops from which yarns are to be unwound by winding units are always held in full stock conditions in stand-by positions of the winding units. New cops are successively carried into cop stand-by positions by way of a cop transporting passage and surplus cops are recirculated from a last one to a first one of the winding units by way of a surplus cop recirculating passage.

Abstract: A full bobbin supply and an empty bobbin ejecting device for an automatic winder disposed between a full bobbin feeding conveyor and an empty bobbin ejecting conveyor. A full bobbin doffed from a spinning frame is fitted on a peg erected on a bobbin carrier and conveyed. The bobbin carrier with the bobbin is stopped at the stand-by position by a first stopper, and then supplied to a yarn running position of the winding unit.

Abstract: A cop transporting system for an automatic winder in which a single automatic winder can wind a plurality of different kinds of yarn at a time. A winder including a number of winding units therein is divided into a plurality of sections each including a plurality of winding units therein as a group, each of the sections having a specific cop supplying passage provided therein along the winding units. Each of the sections have a cop supply device provided therefor and cops fed out from the cop supply devices are transported to the specific supplying passage of the sections corresponding to the cop supply devices.

Abstract: A system for transporting and supplying different kinds of cops to an automatic winder. The system includes a cop feeding passages disposed on one side of the winding units of the winder, a bobbin ejecting passage disposed on the other side of the winding units and dividing devices provided in the cop feeding passage and bobbin ejecting passage which can divide the passages at any desired positions in the direction along the unit so that the automatic winder can be divided into a plurality of sections.

Abstract: A system for transporting various kinds of cops to an automatic winder which includes a number of winding units. The winding units are divided into a plurality of winding sections, whereby a kind of cops from a spinning frame are supplied to and unwound on one of the sections. A cop supplying passage and an empty bobbin returning passage are provided between the sections and the spinning frame so as to form a closed loop.

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.
