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.
Claims18
A cop transporting system for an automatic yarn winder including a number of winding units, comprising:
- means for dividing said automatic winder into a plurality of sections, each section including a plurality of said winding units, each of said sections being adapted to wind a different type of yarn;
- a plurality of cop supplying passages, in like number as the plurality of sections, each of said cop supplying passages being formed along said winding units so as to supply a differing section of the automatic winder;
- a plurality of cop supply devices, in like number as the plurality of sections;
- a plurality, in like number as the plurality of sections, of means for transporting cops fed out from said cop supply devices to the cop supply passages;
- said plurality of means for transporting cops corresponding to said plurality of cop supply devices, to said plurality of cop supplying passages, and to said plurality of sections, in a specific one-to-one correspondence such that different kinds of yarns may be wound in the respective sections of the winder;
- and
- a plurality of hollow disk-formed trays for transporting cops, each of said trays including a hollow peg formed uprightly at the center of said tray, said pegs being adapted to removably fit within and support hollow wooden bobbins forming cores of said cops;
- whereby said trays are transported on said means for transporting cops such that said bobbins are substantially vertically oriented.

A cop transporting system for an automatic winder including a number of winding units, comprising:
- means for dividing said automatic winder into a plurality of sections each including a plurality of said winding units;
- a plurality, in like number as the plurality of said sections, of cop loops, each cop loop comprising a cop circulating conveyor, configured to provide each winding unit of its corresponding section with cops, such that surplus cops circulate around said cop loop until accepted by one of the winding units of said section;
- a plurality, in like number as the plurality of said sections, of cop supplying conveyors, each being adapted to convey cops of a specific type to the cop circulating conveyor associated therewith;
- a device for finding a loose yarn end of a cop and for locating said loose yarn end within the hollow bobbin supporting said cop;
- means for selectively distributing cops supplied from said device for finding a loose yarn end of a cop and for locating said loose yarn end within the bobbin of said cop, by said specific types, to said plurality of cop supplying conveyors;
- a plurality of, in like number as the plurality of said sections, of cop feeding conveyors, each of said conveyors providing cops of the specific type required by an associated one of said sections;
- and
- means for selectively supplying said device for finding a loose yarn end and for locating said yarn end within the hollow bobbin of its cop, by controlled quantities, with each specific type of cop from said cop feeding conveyors.

A cop transporting system for an automatic winder including a number of winding units, comprising:
- means for dividing said number of winding units into a plurality of sections of said automatic winder, each including a plurality of said winding units;
- a plurality, in like number as said plurality of sections, of cop supplying passages, one such passage formed for each section along said winding units thereof;
- a single cop supplying conveyor;
- a plurality, in like number as said plurality of sections, of conveyors communicating from said cop supplying conveyor to each section, respectively;
- a single empty bobbin discharging conveyor, capable of accepting empty bobbins from each winding unit of each of said sections;
- a single empty bobbin unloading device;
- a single cop feeding conveyor, providing cops of a plurality of types from an external source;
- a single device for finding a loose yarn end of a cop and for locating said loose yarn end within the bobbin of the cop;
- a cop storage device, adapted to provide segregated storage areas for a plurality of cops of each type;
- means for sensing the number of cops of each type discharged via said empty bobbin discharging conveyor;
- means for segregating each type of cop into the appropriate one of the storage areas of the cop storage device;
- means for directing a specific type of cop from said cop supplying conveyor to the appropriate one of said cop supplying passages through the appropriate one of said plurality of conveyors communicating therebetween;
- and
- a counter unit for controlling the release of cops of a specific type from said cop storage device;
- said elements cooperating such that cops of all of said plurality of types of cops are provided by said cop feeding conveyor to said device for finding a loose yarn end of a cop and for locating said loose yarn end within the bobbin of the cop, from whence the cops are segregated into specific storage areas, by type, of said cop storage device, whereat they are retained until released by type under the control of said counter unit to proceed along said cop supplying conveyor, from which the cops of a specific type are controllably directed to the specific cop supplying passage of the section of the automatic winder adapted for winding cops of said specific type, whereat one of the plurality of winding units of said section performs a winding operation of said cops such that its empty bobbin is conveyed via said empty bobbin discharging conveyor past said means for sensing the number of cops of each type discharged, to said empty bobbin unloading device.
