Definitions

  • the invention relates to bobbins for receiving a package of roving in a roving frame, and to the bobbin support structure for receiving and rotating such bobbins in a frame.
  • the invention is intended particularly, but not exclusively, for use in a roving frame with an automatic doffer.
  • a roving frame with a bobbin support structure in the form of a spindle mounted upright in a spindle bolster and provided at or near the bolster with a pedestal fitted with a drive dog or detent mechanism to engage and drive a bobbin mounted over the spindle and supported by the pedestal - see for example Swiss Patent No. 236 212 and Japanese Utility Model Published before Examination No. 53/ 41414.
  • Figure 1 shows a hollow metal spindle 10 and a small part only of a conventional spindle bolster 12 in which the spindle is mounted by suitable bearings including rollers 14. Below this bolster, the spindle is provided in known fashion with a drive whorl for rotating it, but since this is conventional and forms no part of the invention, it is not illustrated.
  • the bolster is mounted in known fashion in a spindle carrying beam of a spinning preparatory machine for preparing textile fibre for a spinning frame, e.g. a roving frame.
  • a spinning frame e.g. a roving frame.
  • the present invention is not limited to use with such frames.
  • Spindle 10 is mounted with its axis 16 upright and it receives in use over its upper end a hollow bobbin 18.
  • the bobbin is passed down over the spindle until a frusto-conical shoulder 20 on the bobbin engages a frusto-conical end surface 22 on the upper end of the spindle.
  • the bobbin rests on the surface 22 alone.
  • Surface 22 is formed on an endcap 24 having a shank 26 screw-threaded into the open upper end of the spindle.
  • the material of this endcap may be different from that of the remainder of the spindle, being suitably hardened if required to form an accurate resting surface for the bobbin.
  • the spindle has two diametrically opposite grooves 28 passing completely through its wall. Secured to the shank 26 are two leaf springs 30 projecting through respective grooves 28 so that portions of the springs extend radially outwardly beyond the external surface of the spindle.
  • the outwardly extending portions of the springs pass into grooves formed between longitudinal, internal ribs 32 in the interior of the bobbin and form a positive driving connection with the bobbin - as seen on the left hand side of Fig. 1. Should the springs be initially aligned with ribs instead of grooves, they will be pressed inwardly against their own resilience (as seen on the right hand side of Fig.
  • the internal diameter of the bobbin is larger than the external diameter of the spindle, and a centralising ring 34 is provided on the spindle below the centre of gravity of the bobbin.
  • the spindle has an annular member 36 of trough section secured thereto, the open side of the trough facing upwardly and receiving the lower end of the bobbin.
  • the inner wall 38 of the trough both secures it to the spindle and acts as a centering ring for the bobbin.
  • the outer wall 40 of the trough has an inwardly projecting lip provided by a resilient ring 42 secured to wall 40 in any convenient manner.
  • the ring presents a resilient socket to receive the lower end of the bobbin.
  • a roving tail suitably presented to the bobbin and support structure can be clamped between the outer cylindrical surface of the bobbin and the resilient lip 42 and is thereby secured to the bobbin for winding of a package 44 thereon.
  • Waste material can collect in the trough, which thereby protects the bearings in the bolster 12.
  • the lower end face, that is the axially facing surface, 46 of the bobbin does not contact the bottom wall 48 of the trough so that the portion of the bobbin below shoulder 20 is dependent from the shoulder and does not provide support for the weight of the bobbin or package.
  • accumulated waste in the trough does not adversely affect the disposition of the bobbin.
  • the lower end of the bobbin is provided by an array of teeth 50 which are evenly distributed around the full periphery of the bobbin.
  • the roving tail passes into one of the gaps between the teeth when the bobbin first engages the ring 42, and the roving tail is thereby gathered together and supported and held in good condition for clamping. It will be noted that since clamping occurs between the lip 42 and an outwardly facing surface on the bobbin, i.e. a surface which does not produce any substantial force component supporting the bobbin, there is again no risk of disturbance of the disposition of the bobbin due to accumulated waste on the clamping surfaces.
  • the head portion of the bobbin projects above the spindle and comprises a chamber 52 between the shoulder 20 and a second internal shoulder 54 which also faces the dependent end of the bobbin.
  • the mouth of the bobbin bore at the head thereof is formed with an inwardly convergent frusto-conical surface 56.
  • the head thus formed facilitates automatic doffing of the bobbin with a completed package, since a doffer element with spring or gravity loaded, radially outwardly projecting fingers can push into the bobbin head so that the fingers can engage under the shoulder 54 and lift the bobbin off the spindle.
  • a so-called Casablanca connector e.g. as disclosed in US-A-3 331 567 is suitable for this purpose.
  • the bobbin is made of synthetic plastics material.
  • the outer wall of the bobbin is made as a generally uniform section tube (but formed with the ribs 32) and the shoulders at the head are provided by an additional part inserted into the outer wall and welded thereto.
  • the bobbin support surface in the support structure may be on an element separate from the spindle which is required to hold the bobbin upright. However, it is clearly simpler to integrate the support and alignment functions in the one element.
  • the internal shoulder which rests on the spindle is not necessarily continuous around the inner periphery of the bobbin. It could, for example, be provided by an array of sub-shoulders formed on the individual ribs 32, which can extend further upwards into the chamber 52.
  • the position of the shoulder along the length of the bobbin can be varied, but preferably it is such as to enable use of the upper end of the spindle as the bobbin supporting surface thereon.
  • the holder for the lip 42 is not necessarily formed as a trough, but it preferably has an undersurface protecting the bolster bearings. This can provide a labyrinth seal as seen at 58 in Figure 1.
  • Figure 2 illustrates the preferred form of the teeth 50, although this form is also not essential.
  • the teeth have flanks disposed at an angle a, preferably about 60 degrees although 50 to 70 degrees is acceptable.
  • Each tooth is short- about 3 mm is preferred, but 2 to 5 mm is acceptable.
  • the spacing of the teeth at the lower edge of the bobbin may be about 5 mm, although 4 to 7 mm is acceptable.
  • the outside of. each tooth is preferably chamfered, as indicated at B in Figure 2, to facilitate insertion into the lip clamp.
  • a chamfer angle B of about 6 degrees is preferred although 4 to 8 degrees is acceptable.
  • the overall dimensions of the bobbin will depend upon the size of package to be produced, the dimensions of the roving machine, the design of automatic doffer and a variety of other factors.
  • An important feature is the selection of the length of the dependent portion of the bobbin, i.e. the distance between the shoulder 20 and the end surface 46 of the teeth 50, so that this portion will hang from the endcap 24 and will not rest on the base of the trough 36.
