Definitions

  • ABSTRACT A method and apparatus for assessing the running be havior of textile machines wherein a yarn monitor detects a characteristic at each spindle and a counter is provided at each spindle to count the number of 0ccurrences at detection of the prescribed characteristic so that an evaluating unit receiving the indications from the counter can provide a signal indicating when a prescribed limit has been reached.
  • An object of the invention is to remedy this situation by providing a method of assessing the running behavior of a textile machine comprising a plurality of spindles wherein operational characteristics are counted at each individual spindle, and a signal is generated in the immediate proximity of each spindle when the number or duration of the characteristics exceeds and/or does not reach a predetermined value.
  • This invention also provides an apparatus for assessing the running behavior of a textile machine having a plurality of spindles comprising a yarn monitor, a counter for recording impulses in consequence of a particular characteristic of each spindle, a nominal value pickup for determining the permitted number or duration of characteristics per spindle and a signal generator for indicating when the number or duration of the operational characteristics exceeds the predetermined nominal value and/or does not reach another predetermined value.
  • the predetermined nominal value can be calculated in accordance with the laws of statistics. It is of particular advantage to form the sum of all yarn breakages in the machine in question. in which case the sum and the probability for a certain number of characteristics in the operation of an individual spindle are in a direct mathematical relationship to one another.
  • Yarn monitors advantageously of the kind which function without contact, are used on the spindles for detecting the occurrence of a yarn breakage. releasing a different signal to indicate that the yarn is or is not traveling, depending upon the circuitry used. These signal changes indicate clearly the occurence of yarn breakages.
  • measures have to be taken to ensure that, when the machine is taken out of operation, counting of the yarn breakages is also interrupted because otherwise changes from a traveling yarn to a stationary yarn will occur in the absence of a yarn breakage.
  • FIG. I diagrammatically illustrates a spinning station with the elements associated with it.
  • FIG. 2 shows several spinning stations of the kind shown in FIG. I arranged adjacent one another.
  • FIG. I shows in simplified form part of a ring spinning machine.
  • Untwisted yarn 10 leaves a drawing zone, diagrammatically indicated by a pair of front cylinders II and 12, and passes through a yarn guide 13.
  • the twist required for the strength of the yarn is then imparted to the yarn by means of a traveler I4 in known manner, i.e., by the bobbin 16 rotating on its mounting I7 and by the traveler l4 traveling around the ring IS.
  • the bottom 16 is uniformly wound with the spun yarns, through reciprocating vertical travel of the ring rail 18.
  • a yarn monitor in the form of a detector 20 of known construction is arranged, for example, in the zone between the front cylinders 11 and 12 and the yarn guide 13, its function being to transmit different signals along a line 21 to a counter 22, depending upon whether the yarn I0 is traveling or stationary.
  • the yarn breakages can be derived from this signal and their number stored in counters.
  • electrical stores which are known in various different forms. as the counters.
  • a counter 22 bistable multivibrators with which it is possible to count up to 3.
  • the corresponding circuit has to be such that. when the third yarn break occurs at the spindle in question, a signal lamp 24 is illuminated and. through internal connections, it is ensured that no further counting impulses reach the input of the counter because. on the arrival of the next impulse, the counter would be set back to zero.
  • Another advantage of electrical counters is that they can be set back to zero from a central unit with the result that an evaluation period can begin at the same time for all the bobbins.
  • a machine containing. for example, 200 spindles By means of a busbar 26 to which the counter 22 is connected by means of a line 25, it is possible to determine the sums of the yarn breakages of all the spindles 16 in a central evaluating unit 27. which may typically include a summing circuit for summing the signals received on bus 26 and a level detector for determining when the value in the summing circuit reaches a given level. When these sums are reached, it is possible for example to suppress all further counting.
  • FIG. 1 also shows a switch 29 in the connecting line 21 through which, when the machine as a whole is stopped, the counting impulses are also interrupted by actuating a contactor 30. Stoppage of the yarn as de tected by the yarn monitor because of stoppage of the machine should not, of course, be evaluated as a yarn break.
  • a spindle remains stationary for example for 30 minutes, it follows that thirty impulses are counted by the second counter.
  • the installation can be such that the indicating instrument at the individual spindles responds on reaching a certain number of impulses.
  • Flip-flops can again be used as the second counters. lf for example six flipflops are used. It is possible to count up to 63 (2 l lt is of particular advantage to fix the counting value at which the indicating instrument responds. and to vary the time interval between the impulses. So far as the present example is concerned. the indicating instrument would therefore respond after 63 minutes with an interval between impulses of one minute. if the interval between impulses is 2 minutes. a total stoppage time of l26 minutes would elapse before indication.
  • the cut count of electronic yarn cleaners is another example of operational characteristics.
  • An electronic yarn cleaner normally has a certain average cut count at a certain spindle. Excessive or inadequate impulse counts can be obtained both as a result of disturbances affecting the machine and also as a result of incorrect sensitivity of the yarn cleaner. in this case, it is advisable both to indicate when a certain impulse count has been exceeded and also to indicate if a certain cut count has not been reached after a certain time. These two indications can, of course, be combined into a single indication.
  • a method of assessing the running behavior of a textile machine including a plurality of spindles com prising the steps of detecting operational characteristics at each individual spindle, counting the detected operational characteristics at each spindle, summing the detected operational characteristics from all of said spindles and generating a signal in the immediate proximity of each spindle when the number or duration of the characteristics detected at the given spindle reaches a predetermined value in excess of the average number of detected operational characteristics of the plural spindles prior to detection of a predetermined total number of operational characteristics from all of said spindles.
  • An apparatus for assessing the running behavior of a textile machine having a plurality of spindles comprising yarn monitor means for providing an impulse upon detecting a particular characteristic of the running behavior at each spindle. a counter connected to receive the output of said yarn monitor means at each spindle for counting said impulses representing the occurrences of the detected characteristic at the respective spindle. evaluating means connected to the output of each counter for resetting said counters upon detection of a predetermined total of detected occurrences of the particular characteristic at all of said spindles and signal generator means at each spindle responsive to said counter for indicating when the counter reaches a predetermined count.
  • said yarn monitor means includes at least one yarn detector which tests the yarn for travel without contact therewith.
