Definitions

  • the invention relates to an electronic interrogation device for monitoring a multiplicity of thread running points on a textile machine according to the preamble of claim 1.
  • An interrogation device for monitoring a running sequence of workplaces of a textile machine, for example a ring spinning machine, for thread breakage with a probe passed by the workplaces for contactless recording of electrical signals which are generated when the thread is running correctly and fail when the thread is missing, is from the CH- PS 601 093 and DE-AS 2731 019 known.
  • the probe is guided along the work stations on a guide rail by means of a drawstring.
  • DE 23 13 959 describes a thread break detector according to the preamble of claim 1.
  • This has a collecting electrode, which is influenced by the electric charges carried by the thread, an evaluation circuit connected to the latter, which supplies a control signal for a display or control device, as well as a state connected between the collecting electrode and the display or control device and controlled by a clock generator during the scanning pauses
  • the display or control device maintains the storage device, with the one connecting point of the parallel connection of a charging capacitor and a high-resistance resistor and, on the other hand, the input terminal of a switching path controlled by the clock generator of a sampling switch being directly connected to the collecting electrode, the output terminal of the switching path being connected to the tap of a DC-supplied voltage divider , whose base is connected to the other connection point of the parallel connection mentioned, and the said tap via a capacitor with two is used as a DC voltage / pulse shaper NAND gates, the output of which is led to one input of a flip-flop serving as a memory, the other
  • the invention has for its object to provide an electronic interrogation device of the latter type, which works without mechanical devices and without probe guided along the measuring points and in which no temporary storage of error signals, in this case thread breakage signals, is required.
  • a measuring head M1 to Mn is arranged at each thread run point, for example a ring spinning machine or a flyer.
  • This provides an analog thread running signal as long as the thread is running at the relevant running point.
  • the thread running signal then has a positive value up to, for example, + 5 V and becomes zero if the thread breaks or the thread stops.
  • n bistable control means F1 to Fn Parallel to the measuring heads M1 to Mn, a series connection of n bistable control means F1 to Fn is provided, each of which is assigned to one of the measuring heads.
  • the outputs of each measuring head, such as M1, and the associated bistable control means, such as F1 are connected to the two inputs of a switching means, e.g. B. an electronic switch, such as S1 connected.
  • the output of each switch S1 to Sn is connected to a common signal line SL.
  • the switches S1 to Sn can also be replaced with the aid of an AND gate G1 to Gn and a diode D1 to Dn, as shown in FIG. 6. Further arrangements are also possible which fulfill the same function; for example a resistor R1 to Rn with two diodes D1 to Dn, and d1 to dn (Fig. 7).
  • a clock generator CL which controls the clock inputs C1 to Cn of the bistable control means F1 to Fn via a clock line C.
  • the clock generator CL preferably delivers pulses of a high repetition frequency in the range of several kHz, for example 10 kHz. But you can also work very slowly, for example at 10 Hz.
  • a first AND gate A1 with a negated and a non-negated input forms the output stage of the interrogation device.
  • the negated input is connected to the signal line SL, the other input to the clock line C.
  • the output line or display line of the first AND gate A1 is designated A.
  • a reset AND gate A3 with a negated input is also provided.
  • the negated inputs of the AND gates A2 and A3 are connected to the clock line C.
  • the other input of the AND gate A2 or A3 is connected to the output of the first bistable control means F1 or the nth bistable control means Fn.
  • the negated output Q of the bistable control means F7 controls the data input E1 of the first bistable control means F1, while the output of the reset AND gate A3 is connected to the reset input of the bistable control means F7.
  • the output line of the reset AND gate A3 is denoted by R.
  • a switching stage SS is connected to the display line A, which switches off the machine or only the affected thread runner if a thread break occurs.
  • An indicator stage JS is connected to lines A, C and R, as will be described in more detail in connection with FIGS. 3 and 4.
  • C and C mean the series of clock pulses or negated clock pulses, F1 to Fn the output signals of the bistable control means F1 to Fn; the other output signals are identified by the same designation as the switching elements producing them or the lines assigned to them.
  • All logical switching elements shown in FIG. 1 and the clock generator CL are intended to carry dual H signals or L signals at their outputs.
  • all bistable control means F1 to Fn should be in the idle state, that is to say carry an L output signal; the output signal Q of the bistable control means F7 is then an H signal.
  • the following bistable control means F2 etc. to Fn are set and reset in each case during the period of a clock pulse C.
  • the measuring heads M1, M3 to Mn generate a thread running signal of a positive value, while the measuring head M2 delivers a signal of zero value due to thread breakage.
  • Fig. 2 only the signals F1, F2, Fn and S1, S2, Sn are shown. All F signals are only shifted by one clock; in the case of the S signals, the signal S2 fails, while all the other S signals are simultaneous with the corresponding F signals.
  • the signal line SL now carries the sum of all S signals; that is, the sum signal is an H signal for the duration of all S signals with the exception of the signal S2: during the duration of this signal, the sum signal on the signal line SL has the value L.
  • the logical addition of the negated sum signal SL and the clock pulse in AND gate A1 supplies the output signal A; this has the value L when all measuring heads M1, M3 to Mn are interrogated with the running thread intact, but has the value H when interrogating the measuring head M2 with defective thread.
  • the last four lines of FIG. 2 relate to the pulses formed in the starting circuit A2, F7 and in the resetting circuit A3. Row C of the inverted clock pulses is also shown here, which are decisive for the clock control of these circuits.
  • the output signal on the display line A can be processed in an effective stage SS or JS, FIG. 1, in various ways. It can be used in a known manner to switch off the machine or the thread run point at which a thread break has occurred by means of a switching stage SS. Indicator levels JS for displaying or counting thread breaks are to be explained with reference to FIGS. 3 and 5.
  • FIG 3 shows, as the first embodiment of the indicator circuit JS, a counting stage which registers the thread breaks occurring on the individual measuring heads M1 to Mn in separate counters Z1 to Zn.
  • This indicator circle can be used advantageously on ring spinning machines.
  • This counter stage contains an n-digit shift register SR with a data input connected to the display line A and a shift input which is connected to the clock line C with the interposition of a delay element V.
  • a reset input of the shift register SR is connected to the reset line R.
  • the outputs of the individual cells of the shift register SR are each connected via an AND gate to a counter Z1 to Zn; a second input of each AND gate is connected to a counting line ZL, on which a counting pulse appears at the end of each polling cycle. This counts the H signal contained in a cell in the event of a thread break into the associated counter, in the present case Z2.
  • the shift register SR is reset by a reset pulse on line R.
  • the order of the counters Z1 to Zn is from the back to the front, since the signal on the display line A, which is assigned to the first thread monitor, appears in the rearmost cell of the shift register SR at the time of the counting pulse ZL.
  • the associated spinning position must be stopped via the switching stage SS, FIG. 1; Furthermore, the counting must be interrupted, for example, by opening a switching means (not shown) arranged in the clock line C. After the thread break has been eliminated, the spinning position and the counting are started again by hand.
  • FIG. 4 again shows the signal on the display line A from FIG. 1 and the delayed clock pulse V in the first line.
  • the value of the display signal A which occurs at the same time is inserted into the shift register SR; this is the value H of signal A that occurs simultaneously with the second clock pulse.
  • FIG. 5 shows a simple indicator circuit for displaying a thread running point at which a thread break has occurred.
  • the bistable control means F8 is in the idle state, that is to say carries an L signal at its output.
  • the clock pulses on the clock line C can pass the AND gate A5 via its negated input; they are counted into the counter Z as numbers 1 to n in each polling cycle.
  • the bistable control means F8 is set by a thread break and the H signal thus occurring on the display line A.
  • the AND gate A5 is blocked for the clock pulses, and the counter Z stops and shows the number of the thread runner with the thread break. This number is stored in the memory SP; it can be deleted manually by pressing a key, not shown.
  • the indicator circuit described above is advantageously used for displaying broken fuses on a flyer.
  • switches S1 to Sn can be replaced by an AND gate G1 to Gn and a diode D1 to Dn.
  • the thread monitor M1 and the bistable control means F1 each send an H signal to the AND gate, its output also becomes H. This H signal then goes to the signal line SL via the diode D1.
  • the diodes D1 to Dn serve for decoupling.
  • Fig. 7 shows another embodiment of the switches S1 to Sn, each of which is replaced by a resistor R1 to Rn and two diodes D1 to Dn and d1 to dn.
