Definitions

  • the present invention relates to a device at knitting machines for holding a yarn reserve ready for the immediate yarn need in knitting machines such that the yarn is fed with a very small practically constant tension to the knitting place irrespective of the remaining quantity of yarn on the yarn cone.
  • the different feeders on knitting machines draw off the yarn from the cones in the quantities needed.
  • the diameter of the yarncones decreases and thereby also the angle enclosed by the yarn running off and the axis of the yarn cone.
  • these changes are sufiicient to cause notable changes in the article manufactured.
  • the purpose of the present invention is to provide a device which render possible a knitting with a low and constant yarn tension also at intermittent and varying yarn consumption (Cotton-machines, flat knitting machines and pattern knitting machines of all kinds).
  • Another purpose of the invention is to maintain a controlled (correct) yarn supply or reserve such that a sudden stop of the machine may be avoided and to make the yarn guards superfluous and thus to render possible a lower construction of the machine such that the yarn will be available at any place for the hands of a person of normal height.
  • the method involves practically that all the yarn is rewound before they knitting in such a way that the spool always has a constant diameter and a constant height and is kept in reserve immediately before the knitting place in such a way that bows are eliminated, such bows increasing the tension and eliminating stop devices.
  • Proposals have been made to use a device situated between the yarn bobbin and the knitting place, said device comprising a spool body on which the yarn is wound so as to form a yarn supply and means for controlling the winding on of yarn under the influence of the quantity of yarn wound on the spool body.
  • a certain quantity of yarn is kept as a supply for the immediate need of stitching and the yarn is wound on the spool body-which preferably is cylindrical-perpendicularly to the axis of the spool body and is pulled off essentially in the direction of said axis.
  • the yarn is wound on the spool body which by means of impulses is brought to rotate, in windings situated close to each other which are displaced in direction towards the drawing off place.
  • the windings will be situated loosely close to each other and they could therefor easily be tangled.
  • the yarn quantity kept as a supply on the spool body is controlled thereby that by means of a sensing device for the yarn quantity the rotation of the spool body is controlled in such a way that when the yarn on the spool body is reduced to a predetermined minimum quantity, the spool body is brought to rotate and when the yarn supply at such a rotation is increased to a predetermined maximum quantity, the rotation of the spool body is interrupted.
  • a device provided with a photoelectric cell which is delicate has been used as a sensing device which renders the machine complicated.
  • the invention relates to an improved device for the purpose explained in the aforegoing.
  • the main feature of the invention is to be seen therein that the means for controlling the quantity of yarn wound onto the spool comprises a disk provided wih arms, said disk jou-rnalled in the spool body and its arms extend out through slots in the spool body in such a way that a change in the yarn quantity wound onto the spool body causes a change in the position of the disk, the latter adapted by means of its position change to interrupt or to start the winding of yarn onto the spool body.
  • the arms on the disk cause the yarn during the winding to be situated in windings close to each other and the windings are displaced by means of a sliding along the spool body by swinging the disk towards the discharge end of the spool body when the yarn supply on the spool body approaches the predetermined minimum value. At this swinging of the disk and displacement of the yarn windings on the spool body the yarn winding onto the spool body is restarted.
  • the disk with the arms functions as a sensing device and ensures at the same time that the yarn windings are placed close to each other on the spool body.
  • FIG. 1 shows a device according to the invention
  • FIG. 2 shows a section through an embodiment of the device according to the invention.
  • FIG. 3 is a view on the line IIIIII in FIG. 2.
  • FIG. 1 there is shown an arm 1 which forms a holder for a yarn cone 2.
  • a knitting machine may be provided with e.g., twelve such arms.
  • the yarn 3, as shown by the arrows is drawn off from the cone 2 in upward direction and runs through a yarn eye 4 and then through a slotted or hollow arm 5 down to a yarn spanner -6. From the yarn spanner 6, the yarn runs through a stopper with eyes 7 to a winding device which as a unit has been denoted 8 and which is shown in detail in FIGS. 2 and 3.
  • the yarn 3 is drawn off from the device 8 and runs thereafter via a further guiding eye 9 to the knitting place in the knitting machine (not shown).
  • FIG. 2 a cross section through a preferred embodiment of the winding device 8 according to the invention.
  • This device comprises a cylindric spool body 10 which is carried on a vertical shaft 11. At its upper portion, the spool body 10 is provided with slots 12. There is in the upper portion of the spool body 10 on ball bearings 13 carried a disk 14 having arms 15 which extend out through the slots 12.
  • the cylindric spool body 10 forms the rotor of an electric motor 16 housed in the interior of the spool body, said motor 16 through conduits 17 fed from a current source under the guidance of a micro switch 18.
  • the latter is influenced by the disk 14 which is journalled on a pin 19 for being apt to be swung, said pin 19 extending thnough the shaft 11.
  • the spool body 10 is at its lower end provided with a flange 19" of the same cross section shape as a rail of a railway.
  • a C-shaped ring 20 is adapted to run on the flange 19 for guiding the yarn at its drawing off.
  • the device according to the invention operates in the following way.
  • the yarn 3 is put through the eye 4 and the arm 5, the spanner device 6 and the yarn eyes 7 and is then laid some turns around the spool body 10, put through the running ring 20, through the yarn eye 9 and is then led to the knitting place of the machine.
  • the disk 14 inclines the most and the micro switch 18 is closed so that electric current is fed to the electric motor 16.
  • the spool body 10 will rotate so that that yarn is wound on a surface free of yarn on the spool body.
  • the disk 14 moves the freshly and the previously wound yarn turns (to a certain limit) downwards on the spool body.
  • the disk 14 When at the drawing ofif the yarn reserve 21 decreases, the disk 14 is swung slowly about the pin 19 in such a way that the micro switch 18 at a certain minimum value of the yarn reserve closes the current circuit and the motor 16 restarts for winding a further quantity of yarn on the spool body 10.
  • the yarn reserve then increasing will finally swing the disk 14 in such a way that at a predetermined maximum value of the yarn reserve 21, the disk 14 is brought to a position for interrupting the feeding of current to the motor 16 so that the spool body 10 ceases to rotate.
  • the yarn 3 is always kept ready for being fed to the knitting place with a constant tension and without jerks.
  • a yarn break during the drawing off of the yarn from the cone 2 whereat the knitting machine is to be stopped which requires a certain time, there is always a sufficient quantity of yarn kept in reserve for a careful stop of the machine without any risk of errors in the knitted article.
  • the most important advantage of the present invention is however that with machines having varying or intermittent yarn consumption there is rendered possible a knitting with a constant and a very low yarn tension.
  • the invention has been described in the aforegoing for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims. It is thus possible to use photo electric as well as pneumatic devices for scanning the yarn reserve on the spool body 10 instead of the shown disk 14. Further, the spool body may be shaped somewhat conical or essentially cylindrical and conical only at one end. The motor for driving the spool body at its rotation may be arranged at other places than in the interior of the spool body 10. Another device than the ring 20 is also possible for guiding the drawing off of the yarn.
  • a yarn feeder for textile machines comprising a spool body having slots on which yarn is wound for forming a yarn supply, means for rotating said spool body, means for controlling the winding of yarn on said body by the yarn wound on said spool comprising a pivotally mounted disk provided with arms extending out of said slots so that a change in the yarn quantity on said spool body causes a change in the position of said disk and means controlled by the position of said disk for interrupting or starting said means for rotating said spool body for interrupting or winding yarn on said spool body.
  • a device as set forth in claim 1 wherein means are arranged for starting or stopping the feed of the yarn at its winding on said spool body by adjusting the position of said disk.
  • a device as set forth in claim 1 wherein said means for rotating said spool body is an electric motor and a switch cooperating with said disk controls said electric motor.
  • a device as set forth in claim 1 wherein a track is provided upon said spool body and means are provided cooperating with said track for guiding the yarn during its unwinding from said spool body.
