Claims
- 1. A device for automatically delivering cops from a spinning frame to a plurality of winding units and for automatically delivering empty bobbins from the winding units to the spinning frame, each cop including a bobbin having an opening extending from the bottom of the bobbin and a length of yearn wound about the outer surface of the bobbin, each winding unit including unwinding means for unwinding yarn from a cop, the spinning frame including means for winding yarn about an empty bobbin, said device comprising:
- conveyor means for carrying cops from the spinning frame to the winding units and bobbins from the winding units to the spinning frame;
- a plurality of cop and bobbin supporting trays for independently supporting a cop or bobbin in a vertically upright spaced apart position, the cop and bobbin supporting trays being unconnected to the conveyor means and being carried on the conveyor means so that the trays are circulated on the path of the conveyor means between the winding units and spinning frame, the cops and bobbins carried on the conveyor means being carried by a supporting tray; and
- cop transfer means for automatically moving a tray carrying a cop from the conveyor means into and out of a winding position on the winder,
- wherein the conveyor means, the cop transfer means, the spinning frame and the winding units form a closed loop.
- 2. A device for automatically delivering cops from a spinning frame to a plurality of winding units and for automatically delivering empty bobbins from the winding units to the spinning frame according to claim 1 wherein each suporting tray includes a disk-shaped base and a protrusion extending perpendicularly from the base, the protrusion being insertable into a single bobbin.
- 3. A device for delivering cops to a winding unit and bobbins to a spinning frame, the winding unit having a first side by which cops to be unwound in the winding unit pass and a second side by which bobbins having been unwound in the winding unit pass, the device comprising:
- a plurality of bobbin holding elements for independently supporting a single bobbin or a single cop in a vertical configuration such that material wound about one bobbin supported by one bobbin holding element does not touch material wound about another bobbin supported by another bobbin holding element;
- conveyor means for transporting the bobbins and cops supported by the bobbin holding elements, the bobbin holding elements being detached from the conveyor means, the conveyor means moving adjacent to both the spinning frame and the winding unit; and
- cop transfer means for moving a bobbin holding element from the conveyor means into and out of a winding position on the winder,
- wherein an empty bobbin supported by a bobbin holding element passes by the second side of the winding unit onto the conveyor means and is carried on the conveyor means in a vertically upright position to the spinning frame, and wherein a cop supported by a bobbin holding element is delivered from the spinning frame to the conveyor means and is carried on the conveyor means in a vertically upright position by the first side of said winding unit; and
- wherein the conveyor means, the cop transfer means, the spinning frame and the winding unit form a closed loop.
