Definitions

  • a motor-driven shaft which is common to all bobbin locations or winding units, and to which shaft each of the winding bobbins is operatively connected in a manner permitting for uncoupling or disengagement. If the thread is not present at a bobbin location or winding unit, for example in consequence of yarn or thread breakage, this condition is determined by a suitable sensing member, for example a fceler which cooperates with the thread, and thereafter the relevant drive spindle for the winding unit is disengaged and braked. Then a mechanism which advantageously automatically remedies the thread breakage sucks in the ends of the threads to be knotted together and knots them.
  • the present invention has as one of its prime objects to provide an improved control device which eifectively overcomes the disadvantages of the prior known devices.
  • the present invention is generally characterized by the fact that means are provided for achieving a forward running of each winding bobbin upon completion of the knotting operation at a reduced rotational speed with respect to the normal rotational speed, and further that control means are provided which upon determination of the renewed presence of the thread or yarn permit of a switching of the relevant winding unit from its for- 3,224,693 Patented Dec. 21, 1965 "ice ward running at the aforesaid reduced rotational speed to the normal forward running speed.
  • Another important object of the present invention is to provide an improved control device for the winding units of a winding machine permitting of effective braking of the relevant winding unit when the thread is no longer being wound onto the winding bobbin thereof, then suitably reverses rotation of the winding bobbin in a manner enabling execution of a thread locating and knotting operation, and upon completion of the aforesaid knotting operation rotates the winding bobbin at a reduced forward running speed with respect to the normal forward running speed until it has been determined that the thread has again been knotted and is present for renewed winding, whereupon the winding bobbin is then brought from the reduced running speed up to said normal running speed.
  • a further object of the present invention is to provide an improved control mechanism for a winding machine which first determines after thread breakage has occurred whether the supposedly knotted thread is again intact and in a condition for further winding before placing the relevant winding unit into its normal operating condition.
  • Still another important object of this invention is the provision of an improved control mechanism for winding machines and the like which substantially prevents or minimizes the danger that a broken thread or yarn end will become imbedded in the yarn package of the winding bobbin.
  • Yet a further important object of the present invention is the provision of an improved control mechanism for winding machines and the like permitting braking of the winding unit directly at the winding bobbin when thread breakage or exhaustion occurs, to thereby prevent or considerably minimize the danger that a broken thread or yarn end will become imbedded in the yarn package of the winding bobbin of said winding unit.
  • This drive motor 72 drives via a belt drive 73 a winding bobbin 74 provided with a grooved drum 74a, as is known to the art.
  • a thread or yarn 75 supplied to the winding bobbin 74 is thus capable of being wound upon such winding bobbin 74 to form a yarn package.
  • an electronic yarn feeler or sensing unit 77 which checks for the presence of the thread or yarn 75. Yarn sensing means suitable for this purpose are well known to the art, so that a further description thereof is not believed to be necessary.
  • a suitable electronic motor regulating device 78 is electrically coupled with the drive motor 72 by means of which this motor may be adjusted in a stepless or continuous manner to a predetermined normal or operating rotational speed and in a predetermined rotational sense, for example in accommodation of the different yarn qualities or properties being processed by the crosswinder.
  • the regulating device 78 is thus so constructed that it can adjust the drive motor 72 in response to appropriate externally delivered signals for forward travel of the winding bobbin 74 at the desired normal rotational speed, for return or reverse movement or forward movement, at a smaller rotational speed than the normal forward rotational speed.
  • This regulating device 78 comprises a controllable rectifier circuit wherein the controllable elements are, for example, silicon controlled rectifiers.
  • Regulating devices for motors employing silicon controlled rectifiers suitable for the purposes of the present invention are described in the pamphlet entitled Power Seminar Papers, of Texas Instruments Incorporated. Furthermore, a regulating device of the type suitable for use in the present invention can be obtained from the company Transistor AG. of Zurich, Switzerland.
  • the electric signals for actuating or switching the motor regulating device 78 are transmitted from switch members associated with a control unit or device 79 provided for correcting yarn breakage, whereby one switch member 80 is provided for the normal forward movement, a switch member 81 for the forward movement at reduced rotational speed, and a switch member 32 for the reverse movement of the drive motor 72.
  • the switch members 80, 81 and 82 are actuatable by means of a control shaft 85 driven by a motor 83.
  • the control shaft 85 is provided with mechanical, movable elements 84 provided for carrying out the knotting operation.
  • the switch member 80 for the normal forward running of the drive motor 72 is closed and transmits a continuous signal to the regulating device 78, by means of which said regu- 'lating device maintains the drive motor 72 at its proper normal forward running speed.
  • the electronic yarn feeler 77 during operation of the winding machine determines the absence of the yarn 75, in consequence of yarn breakage for example, then such yarn feeler 77 transmits a suitable signal to an electronic switch 86 which couples-in an electromagnetic relay 87.
  • This relay 87 interrupts the signal for influencing normal forward running of the drive motor 72 and the winding bobbin 74 transmitted via a relay contact 87a, by opening such contact, whereby the drive motor 72 is stopped via the regulating device 78.
  • the spindle of such winding bobbin 74 is advantageously provided with an electromagnetic brake 88 which during the normal winding operation is connected in parallel with the drive motor 72, and which then becomes operative when there is present an interruption of the voltage for shutting-off the drive motor 72.
  • the release or switching-off of the electromagnetic brake 88 occurs parallel with the switching-off of the drive motor 72 by means of the contact 87c of the relay 87.
  • a relay contact 87b is simultaneously closed when the relay contacts 87a and 870 are opened, whereby the control motor 83 is switched-in and the control shaft 85 is brought into rotational movement.
  • the switch member 82 is then initially actuated by the control shaft 85 which then delivers a suitable signal to the motor regulating device 78 which influences a reverse movement of the bobbin drive motor 72, necessary for the knotting operation.
  • the latter is switched-in during the predetermined time provided for such reverse movement via a switch member 89 likewise actuated by the control shaft 85.
  • the signal influencing such reverse movement as well as the signal for the brake 88 is again interrupted, whereupon the winding unit is again brought into its rest condition.
  • the switch member 81 actuated by the control shaft 85 transmits an appropriate signal to the regulating device 78, by means of which such regulating device 78 switches the drive motor 72 to the slower forward speed, whereby again at the same time the brake 88 has applied thereto a voltage via the switch member 89 and, thus, releases the winding bobbin 74.
  • the yarn feeler 77 detects the renewed presence of the yarn 75, then it again transmits a signal to the electronic switch 86 whereupon said electronic switch switches back the relay 87. Consequently, the relay switch or contact 87a is closed, as shown, and transmits to the electronic regulating device 78 the signal for the normal forward running of the drive motor 72 delivered from the switch actuated by the control shaft 85, the latter of which in the meantime has returned into its starting position and, thereby, by opening of the switch member 81 arrests the slower forward movement. As a result, the winding bobbin 74 winds the yarn with a normal forward rotational speed. Simultaneous with the closing of the contact 87a the contact 870 is closed and thereby the brake 88 raised and the contact 87b opened, whereby the control motor 83 is shut-off.
  • a time relay 90 which, after the elapse of a predetermined period of time corresponding to a number of repeated knotting operations, switches-off the control motor 83 and switches-in an optical signal 91, or an acoustical signal or otherwise in order to indicate in an appropriate manner the rest condition of the winding unit 71.
  • the movable elements 84 e.g. cams exactly in the starting position, that is, in order to cut-out the time relay the latter is bridged by a switch 90a actuated by the control shaft 85 via the cam 85a and rod 85b.
  • This switch 90a when the time relay 90 is switched-out allows the motor 83 to rotate further until the starting position of the control shaft 85 is again reached.
  • the illustrated devices permit a braking of the grooved drum and eventually the winding bobbin not only in the presence of yarn breakage, but rather also upon completion of the reverse rotational movement. In this manner it is possible to prevent the danger of winding onto the grooved drum the yarn unwound from the winding bobbin.
  • the aforedescribed electronic operating control device has the advantage in comparison with a mechanical operating variant, that it works practically Without inertia.
  • the relatively long cut-off time from the moment of yarn rupture up to arresting of the winding unit-owing to the inertia of the mechanical starting means and the larger moved masses to be braked, as for example that of the grooved drum and the drive means can be considerably shortened, whereby the danger of pressing-on or imbedding the yarn end in the yarn windings on the winding bobbin can be still further minimized.
  • each winding unit including a winding bobbin adapted to be rotatably driven to wind a yarn package thereon, a supply cop for each winding unit for delivering yarn to its associated winding unit to be wound thereon in a package, a control mechanism for each winding unit comprising drive means for driving the winding bobbin of an associated winding unit at a predetermined normal speed in a first direction of rotation for normally winding yarn into a package, at a speed slower than said predetermined normal speed also in said first direction of rotation for winding yarn into a package upon said winding bobbin to take up the slack in the yarn between its supply cop and said winding unit produced by a knotting operation, and at a speed slower than said predetermined normal speed in a second direction of rotation opposite said first direction
