Abstract
A method and apparatus for changing bobbins in a flyer spinning frame which includes a bobbin rail for supporting bobbins adjacent the flyers movable both vertically and tiltably, the bobbin rail being moved sequentially from an upper bobbin winding position, a lower horizontal position, a forwardly tipped position, then upwardly in the tilted position into a comfortable bobbin doffing position, downwardly into the lower position, back into a horizontal position while in the lower position then finally upwardly into the upper bobbin winding position.
Claims8
An apparatus for changing bobbins in flyer spinning frames having locally stationary, rotatably suspended flyers, a bobbin rail having spindles supported on said frame for both tilting and up and down movements and bobbins rotatably supported on said tiltable bobbin rail, reversible drive means for moving said bobbin rail up and down, means for tipping said bobbin rail outwardly from said frame, control means for reversing the driving direction of said drive means, a plurality of switching devices operatively associated with said drive means, said plurality of switching devices including a switching device actuatable in a position for tipping said bobbin rail outwardly of said spinning frame for operatively conditioning said drive means to raise said bobbin rail, a switching device actuatable in a position of said bobbin rail for removal of said bobbins and for operatively conditioning said drive means to stop further movement of said bobbin rail, and a manually operative switching device actuated by an operator after the removal of the filled bobbins and placing the empty tubes on the spindles for operatively conditioning said drive means to lower said bobbin rail.
A method of changing bobbins in flyer spinning frames having a head and locally stationary, rotatable suspended flyers, a bobbin rail having spindles supported on said frame for both tilting and up and down movements and bobbins rotatably supported on said tiltable bobbin rail, comprising the steps of:
- moving said bobbin rail down by a reversibly driving means, when said bobbins are filled,
- selectively actuating a plurality of switching devices for tilting said bobbin rail outwardly of said spinning frame and for operatively conditioning said drive means to raise said bobbin rail,
- tilting said bobbin rail outwardly from said frame by a bobbin rail tilting means,
- moving said bobbin rail up by said reversibly driving means,
- actuating a switching device in a position of said bobbin rail for removal of said bobbins and for operatively conditioning said drive means to stop further movement of said bobbin rail,
- removing the filled bobbins and placing empty bobbins on the spindles,
- actuating a manually switching device for operatively conditioning said drive means to lower said bobbin rail,
- tilting said bobbin rail inwardly to said frame by said bobbin rail tilting means,
- moving said bobbin rail up to a starting position by said reversibly driving means.
