Definitions

  • the invention relates to an automatic winding machine and the method of operation of the automatic winding machine.
  • the automatic winding machine includes machinery for an automatic change of the supply and take-up spools, and for winding cross-wound coils or cheeses at a plurality of winding stations.
  • any supply spool which runs out at just that time, a thread break occurring in the thread cleaner or elsewhere, or an interruption of the thread on the supply spool, may cause an interruption of the thread connection between the supply spool and the takeup spool. ln all-the aforedescribed cases, the take-up spool exchange device is no longer in a position to automatically start up a new empty spool.
  • the aforedescribed problem is solved by a machine and a method of operating the machine according to which prior to the exchange of take-up spools, the presense of an uninterrupted thread from the supply spool to the take-up spool is ascertained, the thread connection is restored in case the thread is missing and the change of take-up coils is subsequently initiated.
  • a preferred embodiment of the machine of the invention includes a switching member which activates the take-up spool changing device upon reaching a predetermined diameter of the take-up spool.
  • Theswitching member is connected to the take-up spool changing device via a sensing element which ascertains the presence of an uninterrupted thread and controls the takeup spool changing device.
  • each winding station is provided with a thread monitor which is positioned in the path of the thread and senses the thread, the thread tension decreases steadily when the takeup spool runs out.
  • each tension orvelocity dependent thread monitor signals, despite the presence of the thread, an actually non-existent thread break and can therefore initiate an unnecessary knotting operation
  • the thread monitor has been blocked immediately when the winding station was stopped in order to exchange take-up spools.
  • the presence of an uninterrupted thread from the supply spool to the take-up spool is ascertained. That is, either the existing or an additional sensing element remains connected during the entire running-out time of the full take-up spool, or is temporarily connected after the runningout process is completed, but before the take-up spool changing operation is initiated.
  • the exchangeof take-up spools is initiated and undertaken. If the sensing element, however, detects an interruption in the thread, the take-up spool changing procedure is blocked and the thread connection between the supply spool and the take-up spool is first re-establised by a thread tying device. Toaccomplish this, the start of the thread of a new and ready supply spool can be tied to the end of the thread of the take-up spool, or a broken thread end still in the thread tensioner may be foundandreknotted'. After the thread connection is re-established, the exchanging or changing of the spools may be initiated. At this point, it may be advantageous to briefly start upthe take-up spool again prior to the exchange.
  • the automatic winding machine of the invention and the method of the invention therefore eliminate the need for intervention by the operator during the exchange of the take-up spools.
  • FIG. 1 is a schematic diagram, partly in section, of a winding station of an embodiment of the automatic winding machine of the invention.
  • FIG. 2 is a schematic diagram, partly in section, of a modification of the embodiment of FIG. 1*.
  • a take-up spool 1 is driven by a thread guiding drum 2 in the direction. of an arrow 3 for the winding of a thread F on said take-up spool.
  • the takeup spool 1 is rotatably supported in a spoolfi'ame 4.
  • a rod 5 is movably linked to the spool frame 4.
  • the rod 5 has a stop 6 against which a segment-shaped lever 9 rests. The rod 5 adjusts the diameter of the take-up spool 1.
  • a lever 11 executes a swinging motion.
  • a latch 10 permits the interruption of the movement of the lever 11.
  • the lever 11 may be arrested by a pin 12.
  • the swinging motion of the lever 11 is imparted to said lever from a rocking shaft 13 via a lever 14, a rod 15 and a support lever 16, and is transmitted to an angular lever 18 via another rod 17.
  • a friction roller 19 is' linked to the angular lever 18 and produces an intermittent drive between the thread guiding drum 2 and a drive roller 20.
  • the friction roller l9 is also kept away from the drive roller 20 and the drive for the thread guiding drum 2 and for the take-up spool 1 is thereby interrupted.
  • the takeup spool 1 comes to a standstill.
  • a contact 21 is actuated simultaneously with the rocking of the lever 8, and a circuit including another contact 22 and a delay relay 23 is closed.
  • the delay relay 23 is adjustable corresponding to the running-out time for a take-up spool, and after the take-up spool 1 has come to a standstill, said delay relay switches on or actuates a pull magnet 24, causing a latch 25 to release a lever 27.
  • a switching element 29 may then be pushed into the track of a take-up spool changing device via a tie rod 26 and a double lever 28.
  • the take-up spool changing device is known per se and travels along the winding stations, but is not shown in the FIGS. The take-up spool changing device may then be brought to a stop and the take-up spools are exchanged.
  • An example of a take-up spool changing device is disclosed, for example, in U. S. Pat.
  • a sensing element 31 is deflected in the direction of an arrow 32 and a segmentshaped lever 33 is moved under a support projection 34 of the continuously oscillating support lever 16.
  • the lever 11 may therefore be pivotted, rotated or swung into a position in which a latch lever 36 slides off a seat 37 of the lever 11.
  • a switching element 39 is pushed via a rod 38 into the path of a known thread tying device which continuously travels back and forth on a support tube 40.
  • the thread tyingdevice is not shown in the drawing, in order to maintain the clarity of illustration.
  • the thread tying device either reestablishes only the thread connection between the supply spool 30 and the take-up spool l, or first puts a new supply spool in place and then makes a thread connection to the takeup spool in the known manner. Simultaneously with the sliding off of the latch lever 36, the lever 8 is returned to its initial position via a roller 35 and the contact 21 is opened in the process. Since the sensing element 31 returns behind the passing thread F, the contact 22 is also opened. The circuit of the delay relay 23 is thereby interrupted again. The relay 23 is switched .to zero or deenergized.
  • the mechanical thread sensing element 31 may be replaced by electronic monitoring elements, which deliver a suitable switching pulse.
  • the switching pulse may be used to bring the thread tying device into operation.
  • An existing thead may, however, also be checked by a device and the presence of the thread may be ascertained after the running-out process of the take-up spool l is terminated.
  • Another switching pulse may be used to bring the take-up spool changing device into operation and to initiate the spool changing operation.
  • the running out or stopping of the take-up spool l and the thread guiding drum 2 may be monitered directly, by a tachometer generator, for example, instead by the delay relay 23, which must be adjusted to the running-out time of the take-up spool l and the thread guiding drum 2.
  • a tension spring 45 returns the braking sensor 41 to a stop 46.
  • the contact 44 is thereby closed.
  • the pulling magnet 24 is energized and pulls up the latch 25 and releases the lever 27, so that the take-up spool changing device is brought into operation, as in the embodiment of FIG. 1, and may go into operation. If the thread connection is interrupted, the aforedescribed control steps are followed as described with reference to FIG. 1.
  • An automatic winding machine having supply and take-up spools and automatic exchange means for automatically exchanging the take-up spools, the winding machine comprising means for rotating said take-up spool to wind thread thereon, take-up spool diameter sensing means for stopping rotation of said take-up spool and initiating operation of said exchange means upon said take-up spool attaining a predetermined diameter, thread sensing means for indicating the presence or absence of a thread between the supply spool and take-up spool, actuating rneans responsive to said thread sensing means indicating an absence of a thread after said diameter sensing means has stopped rotation of said take-up spool for preventing operation of the exchange means prior to exchange of said take-up spool, thread tying means for tying thread ends extending from said supply spool and said take-up spool, and operable means controlled by said sensing means to initiate operation of said tying means to tie the thread ends when the thread sensing means senses an absence of thread, where
  • said diameter sensing means including a switching element for actuating the exchange means when a specific diameter of the take-up spool is reached and sensed by the diameter sensing means.
  • a method of operating an automatic winding machine having supply and take-up spools and automatic exchange means for automatically exchanging the takeup spool comprising the steps of rotating said take-up spool to wind thread thereon, sensing the diameter of the thread, stopping rotation of said takeup spool and initiating operation of the exchange means upon said take-up spool attaining a predetermined diameter, sensing the presence or absence of a thread between the supply spool and take-up spool, preventing operation of the exchange means prior to exchange of the take-up spool and after stopping rotation of said take-up spool in the event of an absence of tying the thread ends, whereby exchange of the take-up spool is preformed only when a thread is present between the supply spool and take-up spool.
