Definitions

  • One prior art device for detecting thread breaks involves a mercury switch having a feeler riding on the thread being fed to the cable unit. Whenever a break occurs, the feeler drops, activating the mercury switch which signals a timing relay to stop the binder drive.
  • An important disadvantage of this method is that the tension applied to the thread by the feeler is one cause of the very breaks the device is designed to detect.
  • Another prior art detector includes an A.C. generator having its rotor connected to the thread supply spool and its stator' connected to the binding head. As the thread is drawn of, the spool being of either larger or smaller diameter rotates at a different speed than the head thereby producing an A.C. signal related to the speed differential. The signal is present as long as the thread is being payed off the spool, but if the thread should break, the spool which is mounted within the head comes to the same speed as the head, eliminating the speed differential between stator and rotor which generated the signal. The signal failure is then used to turn off the binder.
  • One disadvantage of this detector is its inability to provide a rapid positive indication of thread breakage.
  • a further prior art detector employs a phototransistor mounted within a rotating head to sense the presence of a thread as it enters or leaves the head.
  • the phototransistor is connected to a transmitter which emits a signal as long as a thread is being detected.
  • a receiver mounted on a stationary guard closes a switch to turn off the binder when the signal fails indicating a thread break.
  • the transmitter on each head is tuned to a different frequency to lessen interference from the other heads and to permit positive identification of the particular inoperative binder head. Nevertheless, the possibility of frequency interference still exists and may provide faulty indications.
  • the thread tends to Whip near the head ICC and thus might not be in front of the phototransistor to provide an indication of thread presence and remounting of the detectors is required if the thread is to be wound in the opposite direction.
  • the detecting apparatus of the present invention possesses numerous advantages over the aforementioned prior art detectors.
  • the apparatus may be used in one embodiment to detect the presence of two threads, positioned 18() degrees apart, at a high-speed binder head despite relatively wide variations in thread position which make it difficult to detect the threads on a time basis.
  • the apparatus will detect, in this instance, if either one or both threads break.
  • the detector provides an instantaneous signal when a thread breaks without the possibility of interference which may occur when a different frequency is used for each head in a speed-differential type generator detector and without the delayed response or intermittent tension placed on the thread by conventional electro-mechanical detectors.
  • an object of this invention is to detect the presence of a thread being fed from a rotating binding head despite deviations from a normal thread position.
  • Another object of this invention is to sense the presence of a flamentary material rotating at high speed about a fixed axis.
  • Another object of this invention is to detect one or more threads being fed from a wire binding head which rotates within a wide speed range.
  • a further object of this invention is a rapid functioning gating circuit switching between a high and low input impedance condition.
  • a more specific object of this invention is to detect the presence of one or more threads which may vary from a normal position at each rotating binder head of a multi-unit binder and provide a signal to stop the binding operation if a thread should break.
  • the invention in its broader aspects, comprises a thread or strand break detector for a cable binding operation including means for feeding a strand and detecting means synchronized with the strand feeding means and periodically operable to sense the presence or absence of the strand in a time slot variable with the speed of the feeding means. If a thread is absent, means responsive to the operation of the detecting means stop the operation of the feeding means.
  • the detecting apparatus embodied herein provides a means for preventing runs of unbound cable units or cores by detecting broken binder threads and thereupon stopping the operation of the cable line until the trouble has been corrected.
  • a binder head rotates within the broad speed range of 5()y to 5000 ⁇ r.p.m.
  • a phototransistor gate circuit mounted on a stationary guard is intermittently operated by changes in the light reflected from the rotating head.
  • the detector provides a time slot which is synchronized with the binder head and Varies in width or time duration with the speed of rotation of the binder head.
  • One or more phototransistor detecting circuits sense a designated binder thread in a predetermined sequence as the head rotates and supply a signal through the phototransistor gate.
  • the gated outputs from the detector circuits operate a relay controlling the binder head drive.
  • the apparatus can be used with a single binder thread by inactivating the gate circuit or if several binder threads are required additional channels may be readily added to the circuit.
  • a feature of the circuit is its ability to detect the presence of threads despite variations in thread position of up to in the case of each of two threads.
  • the gate signal from the phototransistor gate circuit is amplied, squared and fed to a first transistorized driver which functions as an A.C. switch to pass signals in a predetermined sequence from one or more detecting circuits to a ip-flop circuit.
  • the thread detecting circuits each comprise a phototransistor, alinear amplifier and a squaring amplifier which sense a designated binder thread as the head rotates. When the required threads are present, i.e. no threads are broken, the outputs from the squaring amplifiers of the detecting circuits are alternately gated to a second driver through the flip-Hop circuit and a one-shot multi-vibrator.
  • the second driver is coupled to a relay control circuit for the binder which holds in as long as pulses are supplied from the detecting circuits. If a thread breaks or is not present because the supply is exhausted, the dip-flop circuit is not activated by pulses from the detecting' channels and the motor control relay circuit drops out stopping the binding operation.

  • the present arrangement of detectors 20 and 30 is designed to detect a pair of threads 40 which are positioned approximately apart but which may vary within plus or minus 20 of their normal position at wrapping speeds of 50 to 5000 r.p.m.
  • the invention in one embodiment comprises a gate circuit 10 and a pair of detector circuits or channels 20 and 30 which alternately sense a designated binder thread 40 which is being fed from a rotating head 65 and wrapped about an advancing cable unit 70 in a helical coniiguration.

  • the control relay 55 in the circuit 50 remains operated as long as a thread 40 is being sensed by the detectors 20 and 30 but when a thread 40 breaks, the relay 55 drops out interrupting the signal to motor control 56, stopping the binder 60 and operating an alarm.
  • the present detecting apparatus would function equally well to detect a plurality of binder threads 40 at each head 65 by merely providing additional detector channels and associated circuits as shown in FIG. 2.
  • the apparatus can also be used to detect a single binder thread 40 by inactivating the gate 10 so that a continuous signal is provided when the channels 20 and 30 detect the presence of the rather fine binder thread 40.
  • the .gate circuit 10 includes a linear amplifier 13 which receives an intermittent signal from the phototransistor 12 representative of a predetermined gating interval and feeds the signal to a squaring amplifier 14 which shapes the wave form to provide positive on-oii signals.

  • the flipflop output is fed to a one-shot multi-vibrator 17 which triggers for a fixed time interval every time it receives a pulse. While the length of the multi-vibrator output pulses is substantially constant, the interval between the input pulses varies in relation to the binder speed and gating interval. Consequently, the one-shot circuit 17 maintains the relay 55 ope-rational over a wide speed range by providing a relatively stable output.
