Device for storage of empty bobbins for a spinning frame
First Claim
1. Empty bobbin storage device in a spinning frame comprising conveyor means mounted above the spinning frame and adapted for restoration to the spinning frame of empty bobbins discharged from a winder associated with the spinning frame, said bobbins having predetermined length and width dimensions and the length dimension being greater than the width dimension, guiding means having a passage for guiding the thus returned empty bobbins to empty-bobbin supply sections associated with automatic bobbin change means annexed to the spinning frame, said passage having an input end adjacent said conveyor and an output end and having a branch point intermediate said input end and said output end to provide left and right passage sections extending from said branch point towards left and right sides of the spinning frame, and distributing means associated with said branch point for selectively distributing the empty bobbins into one or the other of said passage sections, characterized in that, said left and right passage sections have, below said branch point, storage sections for storing a plurality of said empty bobbins, said storage sections, in a cross-section transverse to the direction of movement of the bobbins from said branch point to said output end, having a passage width dimension at least equal to the length dimension of a bobbin and a dimension transverse to said passage width dimension at least equal to the width dimension of a bobbin but less than the passage width dimension whereby each of the bobbins is stored in said storage sections with its length dimension extending in the horizontal direction.

Abstract
The spinning frame of the invention comprises a passage through which empty bobbins returned by conveyor means provided above the spinning frame are guided towards empty bobbin supply sections associated with automatic bobbin changer annexed to the spinning frame. Halfway in the guide passage are a branch point for branching the guide passage into left and right side sections and a distributer for distributing empty bobbins. Below said branch point and halfway in the left and right side sections are storage sections for storing the empty bobbins in horizontal position.

- 8. Empty bobbin storage device in a spinning frame comprising conveyor means mounted above the spinning frame and adapted for restoration to the spinning frame of empty bobbins discharged from a winder associated with the spinning frame, and a passage for guiding the thus returned empty bobbins to empty-bobbin supply sections associated with automatic bobbin change means annexed to the spinning frame characterized in that, halfway in said passage, there are provided a branch point for branching said passage towards left and right sides of the spinning frame for providing two guide passage sections, and means associated with said branch point for selectively distributing the empty bobbins into one or the other of said guide passage sections, and in that, halfway in the left and right guide passage sections, and below said branch point, there are provided storage sections for storing said empty bobbins in horizontal position, said storage sections being zigzag-shaped conduits and each said storage section comprising an upper limit senser for empty bobbins, a lower limit senser for empty bobbins, and separation and forwarding means for empty bobbins extending downwardly of said upper and lower limit sensers.
