Definitions

  • This invention relates to automatic lap-winding machines for use in the preparatory operations of spinning, and more particularly to lapwinding machines having automatically raised racks and associated with cotton scutchers, said lap-winding machine being of the kind in which after the finished lap has attained a certain length an empty lap roller is automatically substituted therefor.
  • the invention substantially consists in connecting the racks to the lap ejecting and supplying device in such a manner that during the raising and lowering of the racks firstly the finished lap is thrown out by the ejector and. then an empty lap roller being in a position in which it is ready for use is caught by the supplying device and guided tothe driving rollers.
  • the ejecting and supplying device is controlled by the racks oris arranged on the racks themselves.
  • One object of the invention is to render the ejecting and supplying device simple in construction and easy to handle, by leaving out the system of rods, eccentrics and the like, which in the known machines are connected to a cam shaft extending through the whole machine and thus being very long, as well as difficult to mount.
  • a further advantage of the invention is that the cam shaft, if not entirely left out, may be considerably shortened.
  • the ejector substantially consists of a guide extending underneath the lap and doffing the same if the rack is raised, the supplying device for the empty lap rollers substantially consisting of a guide fastened on and inclined towards the rack, and of a frame cooperating with the latter and adapted to receive several lap rollers simultaneously, one of which is led from time to time into the oblique guide at the raising and lowering of the racks.
  • the device according to the invention operates continuously, there is sufiicient time for weighing each lap after having been ejected, which is not the case with known machines.
  • the finished laps are carried away by a conveyor which for a certain period stores these laps, thus affording a continuous operation.
  • a further object of the invention is to stop the machine automatically, if the weight of the produced lap is not within fixed limits, with the result that a reliable automatic control is attained.
  • This stopping of the machine is effected by scales which electrically act upon the stopping device of the machine.
  • Fig. l is a side view of the lap machine in the braked position of the racks and during lapping.

  • FIG. 3 is an empty lap roller (Fig. 1) at the ends of which there are pivots 9, over which on either side a rack grips.
  • the lap 2 approaches the lap roller 3 in the direction of the arrow, passing through the series of compression rollers l and. over the two driving rollers 4 and 5 placed at a given distance from each other, against which, at the beginning, the lap roller 3 is pressed by the weight of the racks bearing on its pivots.
  • rollers l and 8 against which the pivots 9 bear.
  • the wrapping on of the lap 2 on the roller 3 is efiected in a well known manner by ahalf-cylin-drical cover It (Fig. 3) whose edge facing the entering lap 2 is bent up.
  • This cover is suspended by a pivot l3 which may slide in a longitudinal slot of the arm l2 which swings under the control of a spring H.
  • a spring controlled lever M of the rack 6 pressing against the pivot l3, keeps the arm I2 in the position shown in Fig. 2.
  • the cover l0 causes the lap 2 to lie against the circumference of lap roller 3.
  • theroller 3 and the racks 6 are lifted in relation to the rollers 4 and 5; thus, after a short movement, the arm I6 of lever I4 engages with a looking finger I1, so that the lever I4 swings away and frees the pivot I3, as well as the arm I2.
  • this arm swings upwards into the position shown in Fig. 4 taking with it the cover II), which has already performed its function of laying the lap on the roller.
  • the automatic stop motion I9 stops the compression rollers I in a well known manner and, according to the invention, starts simultaneously a device which automatically removes the finished lap from its situation under the racks 6, and conveys a fresh empty lap roller in place thereof.
  • the stop motion counter I9 (Fig. 1) swings the lever 2 I around pin 23, which lever in turn swings in the usual wayan arm 23 around pivot 22 from its engaged position by shifting the pin 240, so that the gear wheel 24 disengages from gear 25 fixed .on the shaft of the undermost press roller I.
  • the press rollers I stop, but driving rollers 4 and 5 continue to rotate the finished lap, breaking the layer 2 of the lap.
  • lever 23 actuates by rod 25 the two armed lever 28, which can be a laminated spring swinging aboutpivot 2T, lifting throughits arm 29 the rod 30 so that the two armed lever 32 swings around pivot 3
  • Gear wheel 34 is constantly driven in the direction of the arrow.
  • Cam shaft 35 by toothed segment 31 andgear wheel 38, rotates shaft 39, which by means of gear wheels and 4
  • a lateral L-shaped guide 45 the downward move ment thereof being limited by a stop, said guide following the upward motionof the racks, presses against pivots 9 and freesthe finished lap, which rolls along guide 45 coming into the oblique position shown in Fig. 4.
  • the lap rolls down into a trough 46, which may be a part of a weighing device, as set forth below.
  • the guide 45 In certain cases it is difficult to arrange the guide 45 as low as shown in Fig. 1. In these cases the embodiment shown in Figs. 15 and 16 is preferable.
  • the pivot 44 is in the desired high position and is within a slot
  • the guide 48 must, of course, also be able to come into a high position, which is made possible by connecting this guide to the rack by means of a link H2 pivoted to the rack byapin H3 andto the guide byapin III. Thus if the guide 45 is lifted in the position shown in Fig. 16, it keeps also guide 48 in an elevated situation.
  • a brake shoe 49 (Fig. 1) lies against the friction pulley 50 fixed on shaft 39, thus braking the fall of the racks.

  • the brake shoe 49 is fixed on the shorter armof a lever 54 the longer arm of which'bears a weight 54', the free end of this arm being connected to the adjacent end of'lever 52, which carries the roller 53.
  • weight 54' acts upon brake shoe 49, whichtakes place before the rack has attained its lowest position.
  • the braking becomes momentarily interrupted by cam 56, after which, at the recess '51, the complete braking takes place.
  • by the cam 56 has the advantage that if the racks are stopped by braking .inconsequence of the action of recess 55 before attaining-their lowest position, the releasing of the brake by cam 56 results in the racks finishing their sinking movement. Should the racks reach theinlowermost position before the cam 56 engages roller 53, the momentary releasing of the brake has .no effect.

  • a cord or wire rope 61 is attached to the rackhead and led around a roller 65 pivoted on the frame of the machine, then within a sleeve 95 to an eccentric disc 66, to which it is secured.
  • Another cord 89 is fixed to a roller 69 keyed to the shaft 68 of disc 66, this cord being led through another sleeve 95 to the cover I0.
  • the cover I0 is provided with means I60 adapted to cut the lap when the cover is lowered into its position shown in this figure.
  • These means advantageously consist of sharp elongations or teeth pressing the lap to the driving roller 5 and thus separating the part of the lap which is to be rolled up on the empty lap roller, from the part belonging to the finished roller.
  • the gear 24 is not pivoted in the lever arm 23 as shown in Figs. 1 and 4, but its bearings are fixed and mounted independently from this arm, so that when this arm is swung in a clockwise direction, gear 24 does not move and. rollers I continue their rotation.
  • the layer of the lap 2 is not broken when the finished lap is ejected, as the supplying of the lap is continued by the rollers I.
  • This arrangement makes it necessary to continue the rotation of the lap after its ejection, so that instead of the trough 46 of the foregoing forms, the lap is doffed onto two rollers I6I and I62, constantly driven in one and the same direction for instance by cam shaft 35.
  • rollers I6I and I62 these rollers driving the lap advantageously somewhat faster than rollers 4 and 5, causing a slight tensioning of the lap 2.

  • the pivots 9 of the lap roll down on the oblique guide 14 in the direction of the arrow and fall between claws or paws 16 of a well known conveyor which carries the finished laps away and lays them down at any desired place.
  • the laps may also be taken out of the conveyor by hand.
  • the conveyor 15 extends around two cylinders 11, only one of which is shown in Fig. 8. This conveyor enables the machine to operate continuously, as the doffed laps are raised up making place for the following one.
  • the trough 46 forms part of a weighing device showing the weight of the finished laps on the scale provided on plate 19.
  • the laps dofied directly into the claws of the conveyor, for which purpose for instance the guide 14 is made somewhat longer to take up the ejected lap and to lead it to the conveyor.
  • the laps doffed into the trough of the weighing device I19 are taken out of said trough directly by the claws of the conveyor 15, sothat a swinging or raising of the trough is not necessary.
