Definitions

  • the invention relates to clamping devices in general, and more particularly to clamping devices for supporting bobbins in textile machines.
  • Another object of the invention is to provide such a clamping device which requires relatively little space.
  • a concomitant object of the invention is to provide a clamping device as set forth which is highly reliable in its operation.
  • a tubular bobbin-core member whose axial length exceeds the lesser distance between the two projecting elements, can be releasably secured to the support structure by being inserted into the gap transversely of the direction of movement of the one projecting element, causing the same to be temporarily deflected to the second position thereof.
  • FIG. 2 is a sectional detail view of an embodiment of the present invention.
  • the opposite ends of the arms 4 are arranged to engage a bobbin 7 which is to be supported between these arms and it will be evident that the spacing of the arms 4 by the traverse member 6 is dictated by the axial length of the bobbins 7 which are to be clamped between the arms.
  • the bobbins 7 consist of a yarn package and a bobbin tube 20 onto which the yarn package is wound, for instance by means of cross-winding as indicated in FIG. 2. It is the tubes 20 which are to be supplied in empty condition to the novel clamping device so as to be secured thereto, and the fully wound bobbin is subsequently to be removed from the clamping device.
  • FIG. 2 shows that the free ends of the arms 4 each comprise an inwardly extending pivot portion '8. These pivot portions extend in the direction toward one another, as is clearly evident from FIG. 2.
  • a bearing 9 surrounds and is supported by each of the pivot portions 8, and in turn each of the bearings 9 supports a disc-like inner collar 10 which is rotatable with the respective bearing 9.
  • the collars 10 are provided with an edge face which tapers in the direction away from the gap defined between the free ends of the arms 4, that is in the direction towards the associated arm 4. This edge face is identified with reference numeral 11.
  • the collars 10 are radially recessed axially inwardly of the edge faces 11 to provide an annular wall 12 of smaller overall diameter than the diameter of the collar 10 measured across the edge faces 11.
  • the collar 14 has a second wall portion which tapers conically in the direction towards the gap defined between the respective arms 4 and which thus forms with the tapering edge face 11 of the collar '10 and with the abutment collar 13 a channel-shaped annular space 16 which is open on the side facing the gap between the arms 4 and which conically tapers in the direction towards this open side.
  • annular carrier 17 is received in this space 16 audit will be seen that the carrier 17 has a cross-section corresponding to the frustum of a cone.
  • a suitable biasing means such as a spring 18, is inserted into the space 16 and bears against the collar 13 on the one hand and against the interior surface of the annular carrier 17 on the other hand to thereby urge the carrier 17 to its outermost position in which it extends partially across the gap between the arms 4.
  • FIG. 2 a bobbin 7 including a bobbin-core tube 20 is shown secured to the clamping device and it will be evident that, when this is to be removed, it is simply necessary to exert pressure on the bobbin 7 in the direction transversely of the gap, that is transversely of the movement of the carriers 17.
  • the novel clamping device set forth herein in an exemplary embodiment is particularly suitable, on the one hand, for applications in which minimum floor space is available and in which it is not tolerable that the arms 4 perform movements of considerable magnitude, and on the other hand lends itself admirably to the automation of the tube inserting and bobbin removing process.
  • An automatic bobbin changing device which is well adapted for utilizing the clamping device set forth herein is disclosed in the copending application to which reference has been had in the introductory comments to this specification.
  • Such an arrangement can be stationary and the swinging movement of the arms 4 about the axis 3 can cause the bobbin 7 to bear against the arrangement so as to thereby be ejected, and in turn a further swinging movement of the arms 4 can cause the carriers 17 to bear against a suitably located and held empty bobbin-core tube 20 which will thereby be inserted into the novel clamping device.
  • any such general arrangement will result in simple and highly reliable automation of the bobbin changing process and will thus considerably speed this process which heretofore has always constituted a bottleneck in the high speed yarn manufacturing and winding industry.
  • a clamping device particularly for supporting bobbins in a textile machine, comprising a support structure defining a gap; projecting means carried by said support structure and comprising two projecting elements arranged at opposite sides of said gap; and compressible biasing means serving in compressed condition as sole support for at least one of said elements and mounting the same for frictionless movement transversely of said said gap between a first and a second position in which it is spaced from the other element by a lesser and a greater distance, respectively, said biasing means being operative for permanently biasing said one element to said first position, whereby a tubular bobbin-core member whose axial length exceeds the lesser distance between said elements, can be releasably secured to said support structure by being inserted into said gap transversely of the direction of movement of said one element, causing the same to be temporarily deflected to said second position.
  • said support structure comprises two parallel arms rigidly connected to one another and having respective end portions defining said gap.
  • each of said annular members is circumferentially complete and tapers in one axial direction so as to have a substantially frustoconical cross-sectional configuration, said annular members being coaxial with one another.
  • annular members are so carried by said arms that their axial tapers face one another across said gap.
  • a clamping device particularly for supporting bobbins in a textile machine, comprising a support structure including two parallel arms rigid with one another and having respective end portions defining a gap; projecting means carried by said support structure and comprising a pair of channel-shaped annular carriers each mounted on one of said end portions of said arms and having an open side facing said gap, and a pair of coaxial annular members each having a substantially frustoconical crosssection and being received in one of said carriers with their respective axial tapers facing one another across said gap and with the tapering portions extending outwardly through the respective open side and the bores retained within the respective carrier, at least one of said annular members being movable transversely of said gap between a first and a second position in which it is spaced from the other annular member by a lesser and a greater distance; and biasing means operatively connected with said one annular member for permanently biasing the same to said first position, whereby a tubular bobbin-core member whose axial lentgh exceeds the lesser distance between
  • said biasing means comprising spring means located within the respective carrier and biasing the associated annular member in outward direction.
  • said carriers each include a radially outer annular peripheral member, an inner circular member coaxial with said inner member and defining therewith an annular channel whose cross-section diverges inwardly of said open side, and an annular base member secured to said annular peripheral member and said inner circular member opposite said open side and constituting a bottom wall of said channel.
  • annular peripheral member has a tubular first wall portion and a radially inwardly tapering second wall portion facing said gap.
