Definitions

  • a feeding roller for feeding fibrous sliver in a textile machine has an axial hollow into which an end portion of a driven shaft of the machine extends.
  • a circumferential surface portion of the shaft defines with a corresponding portion bounding the hollow of the roller a circumferentially extending gap which tapers or converges in both circumferential directions.
  • Located in a recess at the widest point of this gap is a cylindrical coupling member which extends into the gap so that, when relative angular displacement of roller and shaft occur, the coupling member will become wedged, in oneor the other narrow end of the gap and thus connect the roller and shaft for joint rotation.
  • the present invention relates generally to textile machines, and more particularly to an improved device for feeding fibrous material in textile machines, particularly open-end spinning machines.
  • the feeding is usually effected by means of a feeding roller which engages the fibrous material and, in response to rotation of the feeding roller, conveys it to the other parts of the textile machine.
  • the feeding roller is conventionally mounted on a shaft of the textile machine driving system or on a suitably driven shaft in general, and the mounting is usually effected either by means of a threaded connection, a pin connection or a wedge connection.
  • the sliver which is fed by the feed roller of course passes about the circumference of the latter, and as a result the impurities in the sliver and yielded to the ambient air, frequently clog the space above the feed roller and adhere to the edges of the openings or surfaces provided for engagement of the spanners or similar tools.
  • impurities Once impurities have thus clogged the space and formed an accumulation, they are eventually entrained by the fibers advancing over and past the feed roller and are finally carried along into the spinning machine, for instance into the spinning system of the same, causing either a marked deterioration of the yarn being spun due to the formation of knots or the like, or resulting in breakage of the yarn which would necessitate shut-down of at least parts of the machine.
  • a further object of the invention is to provide such an arrangement which not only reduces or eliminates the aforementioned disadvantages but also provides a firm and readily release connection of the feed roller with the drive shaft.
  • Still another object of the invention is to provide such an arrangement in which the manufacture, installation and servicing are greatly facilitated, and in which under certain circumstances, the connection between the feed roller and the shaft can even be released during the machine operation.
  • one feature of the invention resides in a textile machine, particularly in an open-end spinning machine, in a combination of a feeding roller for feeding fibrous sliver, having an axial hollow provided with a bottom wall, and driven shaft means having a portion located in the hollow and provided with a transverse flange and with limiting surface means.
  • coupling means which engages the limiting surface means for releasably coupling the shaft means and the roller for joint rotation, with the axial position of the roller on the shaft means being determined by cooperation of the bottom wall, flange and coupling means.
  • the particular advantage of the construction according to the present invention is its simplicity, enabling ready mounting and dismounting of the feed roller even during operation of the machine, without requiring special tools for this purpose.
  • the construction is not only simple but it is inexpensive and reliable in operation.
  • the opposite axial end face of the feed roller from that in which the hollow is formed, that is the end face facing away from the drive shaft can be smooth and uninterrupted so that it is impossible for impurities or fibers to become accummulated on this surface or to adhere thereto.
  • a feed roller for fibrous sliver is identified with reference numeral 1. It is to be mounted replaceably on the shaft 2 which is driven in suitable manner and constitutes a part of a textile machine, for instance an open-end spinning machine.
  • the feed roller 1 is to be rotatable with the shaft 2, and an adjustment member or coupling member 3 of cylindrical configuration is provided for effecting such releasable engagement between the feed roller 1 and the shaft 2.
  • one axial end face of the feed roller 1 is provided with a cylindrical hollow 4 having a bottom wall 5 and being provided in its inner circumferential wall with a recess 7.
  • the cylindrical member 3 is located in this recess being partly accommodated therein and partly projecting inwardly beyond the surface 6.
  • the longitudinal axis of the cylindrical member 3 extends in parallelism with the axis of rotation of the feed roller 1 and thus of the shaft 2 which, as FIG. 1 shows particularly clearly, is in part inserted into the hollow 4.
  • the end portion of the shaft 2 is the part which is inserted into the hollow 4 as FIG. 1 shows, and this end portion is cylindrical in configuration and merges into an eccentric step 8 terminating at a flange 9 the axial front face or end face 10 of which is adapted to bear against the bottom wall 5 of the hollow 4.
  • the end face 10, together with the surface 11 of the flange 9, will determine the axial position of feed roller 1 with reference to the shaft 2.
  • the flange 9 is relieved, for instance on a line 91 which passes tangentially to the cylindrical surface of the eccentric step 8, to obtain the illustrated clearance.
  • the cylindrical surface of the step 8 in turn constitutes a limiting surface 12 which defines with the inner circumferential surface 6 bounding the hollow 4 a gap tapering in both circumferentialdirections, with the member 3 extending partly into this gap.
  • the limiting surface 12 together with the cylindrical wall 13 bounding the recess 7 determines the position of the cylindrical member 3 which is assumed by the latter upon relative angular displacement of the shaft 2 and feed roller 1 in either one or the opposite circumferential direction, at which point a firm wedging connection is achieved between the member 3, the roller 1 and the shaft 2.
  • this connection is obtained when the feed roller 1 and the shaft 2 are angularly displaced with referenceto one another into one of the two extreme positions that is in one or the other circumferential direction determined by the point at which the limiting surface 12 approaches the wall 13 of the recess 7, whereupon a self-locking connection is achieved at two points 14 with the cylindrical surface of the member 3.
  • the surface 12 need not be cylindrical as illustrated but may also be rounded off or straight in part, and that the important consideration is that the limiting surface 12 constitutes in cooperation with the wall 13 of the recess 7 the aforementioned two self-locking points 14 defining the position of the cylindrical member 3 in the gap between roller 1 and shaft 2 when the two elements are firmly connected with one another by means of the member 3 upon relative angular displacement.
  • a feeding roller for feeding fibrous sliver, said feeding roller having an axial hollow provided with a bottom wall; a driven shaft means which is to be removable from said feeding roller, said shaft means having a portion located in said hollow and provided with a transverse flange and with a limiting surface means; and coupling means engaging said, limiting surface means and coupling said shaft means and said roller for joint rotation, the axial position of said roller on said shaft means being determined by cooperation of said bottom wall, flange and coupling means, and said coupling means being disengageable for permitting removal of said shaft means and roller from one another.
  • said limiting surface means is a peripheral limiting surface portion defining with an inner circumferential surface bounding said hollow a clearance which tapers in both circumferential directions, and wherein said coupling means comprises a coupling member located partially in said clearance.
  • said coupling member being cylindrical and having a longitudinal axis which parallels the longitudinal axis of said shaft means.
  • said roller having a recess provided in said inner circumferential surface; and wherein said cylindrical coupling member is located partially in said recess.
  • said shaft means having an eccentric stepped section and said limiting surface portion being a cylindrical circumferential surface of said section.
