Definitions

  • the invention relates to a method for changing roving bobbins on a ring spinning machine according to the preamble of claim 1.
  • the invention also relates to a device for carrying out this method according to the preamble of claim 4.
  • the present invention aims to teach this CH patent application (the purpose of which was the disadvantages of CH-PS 555902 and the DE-OS 3034477 and manual re-plugging of the bobbins and to enable a simple, more cost-effective system, faster changing of the bobbins, avoiding work peaks during the bobbin or sliver change, manual as well as automated operation and a more reliable spool change) develop and in particular to enable practically complete automation and to make the material flow easier and faster.
  • the ring spinning or twisted textile machine 2 fully shown in FIG. 1 and partially shown in FIG. 2 has a 6-row creel for roving bobbins, consisting of three creel longitudinal rows per machine longitudinal side, namely from a first longitudinal row 4.1 of work positions adjacent to the machine longitudinal center plane 3, a second Working position longitudinal row 4.2 and a third longitudinal row as a spare row 4.3.
  • a means of transport in the form of an endless drive belt 6 that runs upright (a chain would also be possible) is stretched horizontally around the machine 2 by means of deflection rollers 7.
  • At the lower end of the drive belt 6, at least one pushing element or tappet or conveying means or driving means 8 is fastened, which can be moved in opposite guide rails 11 by means of sliding shoes 10.
  • a feed ring track 14 formed by baffles 12 is arranged below the pair of rails 11.
  • the baffles 12 form a pair of rails running on both sides of a longitudinal opening 13, the longitudinal openings 13 of the transverse entry tracks 16 opening into an identical longitudinal opening 13.1 of the discharge track 15.
  • a straight path lying in the longitudinal plane 3 of the machine and at the same height as the feed path 14 serves as the discharge path 15, which is formed by identical guide plates 12.
  • Path branches 16 inclined at an angle of 90 degrees to the machine center plane 3 (the same path branch or transverse entry path has been shown twice in FIG. 2) connect the feed path 14 to the discharge path 15.
  • the empty bobbin or sleeve 20 has a circular protective plate 23 made of a rebound-free plastic, the outer diameter 24 of which is slightly larger than the diameter 25 of a largest or full yarn package 26, but is slightly smaller than the outer diameter 27 of the support disk 17. Differences of a few millimeters are sufficient.
  • bobbins 20.1 in the first longitudinal row 4.1 all with the same yarn package, for example 1/4 of the full yarn package 26, while all the bobbins 20.2 in the second longitudinal row 4.2 3 / 4 yarn package and all reserve bobbins 20.3 serving alternatively for bobbins 20.1 and bobbins 20.2 have been wound up in the 3rd longitudinal row 4.3 4/4 yarn package (FIG. 2, left).
  • one spool 20.1, one spool 20.2 and one spool 20.3 are located on a path branch 16 leading beyond the working positions of the spools 20.1 and 20.2 and also beyond the intended reserve position of the spool 20.3 in the gate.
  • the path branch 16 points near the feed path 14 as Soft input blocking means 30 and near the removal path 15 an output blocking means 31, which blocking means 30, 31 essentially hold together the three provided supports 18 of the coils 20.1, 20.2 and 20.3 (it does not matter a few millimeters).
  • the distance between the two locking means 30, 31 can vary depending on the locking means 30, 31 cooperate with the support disks 17 or the guides 19 of the carrier 18.
  • the sliver deflecting rod 33 has three helical turns or grooves 35.1, 35.2 and 35.3, which are advantageously designed to be continuous.
  • the fuse 34.1 of the bobbin 20.1 runs through the groove 35.1, also called the end of the sliver position, which is closest to the path branch 16, to the corresponding drafting system.
  • the fuse 34.2 runs through the groove 35.2 and also to the corresponding drafting system.
  • the fuse 34.3 of the reserve spool 20.3 lies in the groove 35.3 located furthest from the path branch 16, also referred to as the match start position, and is held in a ready position, for example in a changeover condenser 37.
  • a sensor 38 which indicates the match end of the match 34.1 gives a signal 39 to the match guide rod 33, to the two blocking means 30, 31 and to the changeover condenser 37.
  • the blocking means 31, here advantageously in the form of the guide plates 12 arranged and cooperating with the guide 19 of the carrier 18 pivot flap removes from the locked position by pivoting away.
  • a longitudinal leg 41 of the switch 30 swings open (FIG.
  • the match deflecting rod 33 makes a rotation, as a result of which the matches 34.2 and 34.3 are guided to the left towards the path junction 16. This frees the groove 35.3 for the new fuse of the coil 20.4.
  • a continuous crossmember 43 is advantageously provided.
  • each carrier 18 is continuously conveyed in one direction 42 by an individual tappet 8. However, it is also possible to push a whole group of carriers 18 in front of one another with a plunger 8. To reduce friction, the surfaces of the support disks 17 that come into contact with the guide plates 12 can be provided with embedded balls.
  • the plunger 8 has a tapered shape that is flattened conically in the running direction, one of the side surfaces 48 supports or terminates the change in direction of the carrier 18, initiated by the longitudinal leg 41, onto the web junction 16.
  • a common transport lane 15 serving two machine longitudinal sides can be used, in particular if a risk of collision is avoided by staggering over time.
  • the machine longitudinal plane 3 there is a conveyor belt 52 running above deflection rollers 50 and having only a single kidney-shaped conveyor belt 51 on its outer surface, which can be brought into engagement with the circumferential surface of the support disks 17, above the conveyor path 15.
  • the carriers 18 can be on a feed path 55 from the flyer and a discharge line 56 to the flyer can be conveyed smoothly by a carrier tape transport device of a known type.
  • the transfer stations of the transport systems are identified by reference number 57.
  • the discharge path 56 crosses the drive belt 6 by means of an incline. Therefore, it may be necessary to adjust the edge of the protective plate 23 accordingly.
  • the bobbins have an approximate winding time of 3 hours, after which a transport train or a transport thrust of, for example, 96 bobbins can be conveyed to a ring spinning machine with, for example, 960 spinning positions. Since the bobbins of the first longitudinal row 4.1 become empty at about the same time, it can be assumed that adjacent spinning stations are operated with two transport trains 192. The supply of reserve bobbins for the entire ring spinning machine therefore takes about 30 hours. Since the bobbins have an approximate unwinding time of 60 hours, In this case, the bobbins in the first longitudinal row 4.1 in the starting position have wound up a 1/2 package of yarn.
  • the removal belt 52 can only be set in motion after an entire transport train has been changed, so that the empty spools can be conveyed back to the flyer in a closed transport train. Under certain circumstances, no buffer trains are necessary.
  • a plurality of sliders 51 can be provided, the guide plates 12 can be formed by angle irons, the yarn packs in the second longitudinal row 4.2 in the starting position can have a maximum size, instead of the plunger 8 shown, a movable chain can be provided under a guide plate 12
  • Driving pins are used, to reduce the outer diameter 27 of the support disks 17 and thus the width of the transport tracks 14, 15, intermediate disks can be used without coils, changes in the inclination of the track branches 16 would be readily possible, the discharge section 56 can be passed under the drive belt 6, which Carrier disks 17 can be hollow or provided with reinforcing ribs, etc.
  • the feed section 55 and the discharge section 56 can also be combined to form a common transport path running between the flyer and the ring spinning machine.
  • a transport train that can be lowered by a trolley can have support rails on which the supports 18 are carried, the supports 18 being brought to the transport track 14 in the transfer station 57.
