Abstract
A method, of and apparatus for, creeling bobbins into a working position on a ring spinning machine wherein rails are arranged above the ring spinning machine, these rails extending substantially parallel to the longitudinal axis of the ring spinning machine. The rails accommodate trolleys movable therealong and carrying bobbins placed thereon. Connecting means serve to connect the rails to a rail arrangement leading to the ring spinning machine. In operation, the trolleys are transported onto the rails above the ring spinning machine and the full bobbins are brought into their working position.
Claims25
An apparatus for creeling bobbins into a working position at a ring spinning machine, comprising rail means arranged above the ring spinning machine, said rail means extending substantially parallel to the longitudinal axis of the ring spinning machine and comprising input rails, creel rails and exit rails, wherein said creel rails are arranged at a lower height than the input rails and exit rails, each of said creel rails having operatively associated therewith one of said input rails and one of said exit rails, each of said creel rails including a pivotable input section and a pivotable exit section, each of the creel rails being connected via its pivotable input section with its associated input rail and via its pivotable exit section with its associated exit rail, trolleys movable on said rail means for carrying bobbins placed thereon, means for selectively pivoting each input section from a first position into a second position connecting the associated input rail with its creel rail for transferring trolleys carrying full bobbins from such input rail to such creel rail into a bobbin working position, means for selectively pivoting each exit section from a first position into a second position for transferring trolleys with empty bobbins from the associated creel rail to the associated exit rail, each input section and its associated exit section when assuming their respective first positions disconnecting the associated creel rail from the associated input rail and exit rail to prevent transfer of trolleys from the associated input rail to the associated creel rail and from the latter to the associated exit rail in order to maintain the trolleys on the associated creel rail in said bobbin working position, a rail arrangement operatively associated with the ring spinning machine and connecting means for operatively connecting the rail means with the rail arrangement.
An apparatus for creeling bobbins into a working position at a ring spinning machine, comprising rail means arranged above the ring spinning machine, said rail means extending substantially parallel to the longitudinal axis of the ring spinning machine and comprising input rails, creel rails and exit rails, wherein said creel rails are arranged at a lower height than the input rails and exit rails, said creel rails including a pivotable input section and a pivotable exit section, the creel rails being connected via the pivotable input section with the input rails and via the pivotable exit section with the exit rails, trolleys movable on said rail means for carrying bobbins placed thereon, a rail arrangement operatively associated with the ring spinning machine and connecting means for operatively connecting the rail means with the rail arrangement, said exit section being provided with means defining a roll-back stop device for impeding the rolling back of the trolleys and with stop latch means acting in the direction of transport of bobbin tubes, said input section being provided with means defining a roll-back stop device for impeding the rolling-back of the trolleys, and wherein the roll-back stop device of the input section and the stop latch means of the exit section are arranged in such a manner that they secure the trolleys disposed therebetween against horizontal displacement and thus maintain the bobbins suspended from the trolleys in their working position at the ring spinning machine.
A method of creeling bobbins into a working position at a ring spinning machine by means of a transporting rail arrangement forming a closed loop for transporting trolleys carrying full bobbins from spinning preparatory machines and trolleys carrying empty bobbins back again to the spinning preparatory machines, comprising the steps of transporting trolleys onto a rail arrangement provided above the ring spinning machine, moving the trolleys carrying full bobbins via a sloped input section of the rail arrangement above the ring spinning machine as they move onto the rail arrangement above the spinning machine and owing to the overweight of the full bobbin trolleys, the trolleys carrying the empty tubes are pushed-off the rail arrangement above the ring spinning machine onto the transporting rail arrangement, thus bringing the full bobbins into their working positions at the ring spinning machine at such rail arrangement.
