Definitions

  • the invention relates to a bobbin changing device on a spinning device, according to the preamble of claim 1.
  • a spinning device of the type specified is known, for example, from document CH-A-643 308.
  • the extension which can be attached to the free end of the spindle or the bobbin serves to wind up a short piece of yarn next to the bobbin before it is removed from the spindle.
  • the extension is needed especially when it is not possible to place the short piece of yarn next to the other end of the spool e.g. to wind on the spindle, for example because the full bobbin no longer fits in the same place due to the limited dimensions of the bell-shaped thread guide member.
  • the object of the invention is to provide a bobbin changing device which can carry out a bobbin change on a spinning device of the type specified completely automatically and in a simple manner.
  • the spinning device shown has in the usual way a spindle 1 which is rotatable about its axis and which is carried on a spindle bench 2.
  • the spindle drive (not shown) for the spindle 1, usually a belt, is accommodated in the spindle bank 2.
  • the spindle bench 2 is guided vertically displaceably on columns 4 standing on a base 3.
  • the sliding drive for the spindle bench 2, e.g. Chains running over drivable sprockets are also not shown.
  • a console 5 is arranged, in which a bell-shaped thread guide member 6 coaxial with the spindle 1 is rotatably mounted.
  • the console 5 also contains a drive and / or braking device (not shown) for the thread guide element 6.
  • the thread 7 coming from a drafting system enters the same at the top in the axis of the thread guide element 6 and then runs inside the thread guide element 6 up to its lower edge . At this lower edge, the thread passes through a guide opening 6.1 (only shown in FIG. 2) and is then wound onto a bobbin tube 8 arranged on the spindle 1.
  • an extension 9 is detachably plugged onto which a piece of yarn of limited length is wound before a bobbin change.
  • the bobbin change is carried out by an automatically operating bobbin changing device, the essential elements of which are the following: a bobbin holding element 10, a first supporting element 11 and a second supporting element 12.
  • the bobbin holding element 10 and the supporting elements 11 and 12 are each driven transversely to the axis, not shown the spindle 1 is movable.
  • the coil holding element 10 can for example have the shape of an elastic pin which can be inserted into the upper end of a coil sleeve 8 in order to hold the coil sleeve or coil.
  • the first support element 11 can be a fork-shaped element which can be pushed between flanges 9.1 and 9.2 (FIG. 2) of the extension 9 in order to hold the extension 9 against axial displacement.
  • the second support element 12 can also be a fork-shaped element which can be pushed under a coil former to hold it against axial displacement.
  • a transport device for empty bobbin tubes 8 and full bobbins is arranged on the base 3, for example in the form of a band 14 running in a rail 13 perpendicular to the plane of the drawing, on which pins 15 are each carried for fitting a bobbin or a bobbin tube.
  • an automatically operating control device (not shown) is available, which controls the following with reference to FIG. 4 to 21 described movements of the parts described causes.
  • the spindle bank 2 Before switching off the spinning device (ie the rotary drives of the spindle 1 and the bell-shaped thread guide member 6), the spindle bank 2 is set to the height shown in FIG. 4, so that the extension 9 on the upper end of the full bobbin 8.1 on the lower edge of the Thread guide member 6 is aligned. A piece of yarn of limited length is wound onto the extension 9. Then the spinning device is turned off.
  • the spindle bench 2 is then lowered to the height shown in FIG. 5 in order to align the extension 9 to the height of the first support element 11. In this position, the parts are also shown in Fig. 2.
  • the first support element 11 is then moved to a location in the continuation of the spindle axis, so that the first support element 11 now carries the extension 9 and holds it against further axial displacement.
  • the coil holding element 10 is moved to a location above the coil 8.1 in the continuation of the spindle axis.
  • the spindle bench 2 is then raised again somewhat, so that the coil holding element 10, as shown in FIG. 9, enters the upper end of the coil 8.1 in order to hold it in place.
  • the second support element 12 is pushed under the coil 8.1 in order to hold it against axial displacement downwards.
  • the second support element 12 is particularly necessary when the spindle 1 and the coil sleeve 8 are somewhat conical and therefore adhere firmly to one another.
  • the spindle bank 2 is then lowered all the way down to the position shown in FIG. 11 in order to pull the spindle 1 out of the coil 8.1 held by the coil holding element 10 and by the second support element 12.
  • the second support element 12 is then pulled back into its starting position next to the spindle.
  • the coil holding element 10 with the coil 8.1 is then moved into the position shown in FIG. 12 over an empty pin 15 of the conveyor belt 14.
  • the bobbin holding element 10 places the bobbin 8.1 on the mentioned pin 15 of the conveyor belt 14 and then withdraws upward out of the bobbin 8.1, as shown in FIG. 13. (The pin 15 of the conveyor belt holds the spool 8.1 with a greater force than the spool holding element 10.)
  • the bobbin holding element 10 then enters the bobbin tube 8 at the top and pulls it off its conveyor pin 15.1, see FIG. 15. (The pin 15.1 holds the bobbin tube 8 less strongly than the bobbin holding element 10.)
  • the spindle bench 2 is then raised, so that the spindle 1 enters the coil sleeve 8 as shown in FIG. 17 and is clamped in it.
  • the spindle bank 2 is then lowered again somewhat with the coil sleeve 8 according to FIG. 18 in order to detach the coil sleeve from the coil holding element 10.
  • the first support element 11 can now be pulled back from the extension 9, FIG. 20.
  • the spindle bench 2 is then raised further, and the spinning device starts again as soon as the extension 9 with the short piece of yarn wound thereon enters the bell-shaped thread guide member 6.
  • 21 shows the position with the spindle bank 2 fully raised, in which the formation of the new winding on the lower end of the bobbin tube 8 is started.
