Method and apparatus for transporting roving bobbins in a spinning factory
First Claim
1. A method for transporting a plurality of roving bobbins between a floor at which a plurality of roving frames are installed and places for carrying out a roving bobbin exchanging operation before ring spinning frames installed on another floor, said method being applied in a spinning factory wherein roving frames and ring spinning frames are installed on different floors respectively, and bobbin carriages provided with a plurality of bobbin hangers can be transported to said places for carrying out said roving bobbin exchanging operation by means of a guide rail system arranged on a ceiling of said floor on which said ring spinning frames are installed, comprising the steps of:
- forming a transporting passage for transporting roving bobbins from specified positions on said floor on which said roving frames are installed to corresponding positions for transferring roving bobbins on said guide rail system,transporting a plurality of full packaged roving bobbins doffed from roving frames from said transferring positions to said places for carrying out said roving bobbin exchanging operation by displacing said bobbin carriages along said guide rail system, after completion of an operation of transferring full packaged roving bobbins doffed from said roving frames, by displacing said full packaged roving bobbins through said transporting passage,transporting a plurality of empty roving bobbins created by said roving bobbin exchanging operation from a place whereat said operation was carried out to a desired transferring position by displacing said bobbin carriages along said guide rail system, and then transferring said empty roving bobbins from said bobbin hangers of said bobbin carriages carried to said floor on which said roving frames are installed by transporting said empty roving bobbins taken from respective bobbin hangers of said bobbin carriages carried to said transfer position through said transporting passage,said transportation of said full packaged roving bobbins through said transportation passage comprising sequential stepwise unit lifting operations of lifting a plurality of pairs of full packaged roving bobbins towards corresponding transfer positions on said guide rail system from corresponding specified positions, with a predetermined identical interval (a) between adjacent pairs of full packaged roving bobbins being longer than a length of said roving bobbin, while maintaining a constant axial distance between each pair of full packaged roving bobbins,said transportation of empty roving bobbins through said transportation passage downwards comprising sequential stepwise unit operations of displacing said empty roving bobbins downwards, with an interval identical to said interval of said upward transportation of full package roving bobbins, with an axial interval of said pair of empty bobbins being identical to said axial interval of said pair of full packaged roving bobbins during said upward transportation of full packaged roving bobbins.

Abstract
A method and apparatus for transporting roving bobbins in a spinning factory utilizing a factory building having several floors for the installation of spinning machines such as roving frames and ring spinning frames, between specified positions on a floor where roving frames are installed and positions for carrying out a roving bobbin exchanging operation for ring spinning frames, wherein a guide rail system for displaying a plurality of bobbin carriers provided with a plurality of bobbin hangers is suspended from the ceiling of the floor on which the ring spinning frames are installed and transporting passages, provided with apparatus for displacing a plurality of pairs of roving bobbins by successive unit cycle operations composed of a first upwards displacing operation and a second downwards displacing operation, is arranged between each of the above-mentioned specified positions and a corresponding transfer position for the bobbin carriages at which the roving bobbins can be transferred thereto and therefrom at the uppermost position thereof, and capable of transferring roving bobbins between the above-mentioned specified position and the displacing means at the lowermost position of the transporting passage.

1. A method for transporting a plurality of roving bobbins between a floor at which a plurality of roving frames are installed and places for carrying out a roving bobbin exchanging operation before ring spinning frames installed on another floor, said method being applied in a spinning factory wherein roving frames and ring spinning frames are installed on different floors respectively, and bobbin carriages provided with a plurality of bobbin hangers can be transported to said places for carrying out said roving bobbin exchanging operation by means of a guide rail system arranged on a ceiling of said floor on which said ring spinning frames are installed, comprising the steps of:
-
forming a transporting passage for transporting roving bobbins from specified positions on said floor on which said roving frames are installed to corresponding positions for transferring roving bobbins on said guide rail system, transporting a plurality of full packaged roving bobbins doffed from roving frames from said transferring positions to said places for carrying out said roving bobbin exchanging operation by displacing said bobbin carriages along said guide rail system, after completion of an operation of transferring full packaged roving bobbins doffed from said roving frames, by displacing said full packaged roving bobbins through said transporting passage, transporting a plurality of empty roving bobbins created by said roving bobbin exchanging operation from a place whereat said operation was carried out to a desired transferring position by displacing said bobbin carriages along said guide rail system, and then transferring said empty roving bobbins from said bobbin hangers of said bobbin carriages carried to said floor on which said roving frames are installed by transporting said empty roving bobbins taken from respective bobbin hangers of said bobbin carriages carried to said transfer position through said transporting passage, said transportation of said full packaged roving bobbins through said transportation passage comprising sequential stepwise unit lifting operations of lifting a plurality of pairs of full packaged roving bobbins towards corresponding transfer positions on said guide rail system from corresponding specified positions, with a predetermined identical interval (a) between adjacent pairs of full packaged roving bobbins being longer than a length of said roving bobbin, while maintaining a constant axial distance between each pair of full packaged roving bobbins, said transportation of empty roving bobbins through said transportation passage downwards comprising sequential stepwise unit operations of displacing said empty roving bobbins downwards, with an interval identical to said interval of said upward transportation of full package roving bobbins, with an axial interval of said pair of empty bobbins being identical to said axial interval of said pair of full packaged roving bobbins during said upward transportation of full packaged roving bobbins. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. An apparatus for transporting a plurality of roving bobbins between a floor at which a plurality of roving frames are installed and places for carrying out a roving bobbin exchange operation before ring spinning frames installed on another floor, said apparatus being applied in a spinning factory wherein roving frames and ring spinning frames are installed on different floors respectively, and bobbin carriages provided with a plurality of bobbin hangers, aligned with an identical pitch, can be transported to said places for carrying out said roving bobbin exchanging operation by means of a guide rail system arranged on a ceiling of said floor on which said ring spinning frames are installed, comprising,
at least one lifting means for stepwisely displacing of pairs of pegs, which are capable of temporarily holding roving bobbins respectively, between specified positions on said floor wherein a plurality of roving frames are installed and said guide rail system of said floor wherein a plurality of ring spinning frames are installed, at at least one guide rail of said guide rail system, provided with first transfer positions for carrying out a transfer operation of said roving bobbins from said pegs to corresponding bobbin hangers of said bobbin carriage positioned thereat, and vice versa, each of said lifting means being provided with a second transfer position adjacent to a lower end portion thereof.
