Definitions

  • the invention relates to a method and a device for determining maintenance intervals on a spinning machine, which contains at least one work organ performing work cycles.
  • the object of the invention is to create a method and a device of the type mentioned at the outset by which the determination of maintenance intervals is improved.
  • This object is achieved in that a maintenance requirement is determined, for which purpose a number of work cycles is defined as a limit for at least one work organ, after which a maintenance operation is to be carried out, the work cycles of the at least one work organ are paid, and that after the work cycle has been reached A signal indicating the need for maintenance is set.
  • the operating speeds of spinning machines depend heavily on the respective spinning parameters. For example, the spindle speeds of cotton ring spinning machines are often between 12,000 and 18,000 rpm, depending on the material, fineness, rotation, ring diameter, etc. If maintenance intervals were determined using an operating hours counter, this would result in, for example, after an operating time of 1,000 hours between 0.7 x 109 - at a spindle speed of 12,000 min ⁇ 1 - and 1.1 x 109 - at a spindle speed of 18 000 min ⁇ 1 - spindle revolutions can be achieved. In contrast, the invention determines a need for maintenance which is adapted to the actual load conditions due to the operating speeds.
  • the predetermined number of work cycles of the work organ, according to which a maintenance operation is to be carried out is corrected taking into account the working speeds of the spinning machines and the duration of the respective presence of a working speed in such a way that the higher the working speed, the predetermined number of Working cycles are reduced and increased at low working speed.
  • Higher operating speeds lead to a much greater load on the working elements of a spinning machine.
  • the configuration makes it possible to weight high operating speeds by means of a corresponding correction in such a way that the shortening of the maintenance interval goes beyond the extent of a linear dependence between the maintenance interval and the operating speed difference.
  • means are provided for detecting the number of work games carried out, which are connected to an evaluation device which contains a comparator for comparing the number of work games carried out with a predetermined limit value of work games and which is connected to a signal transmitter indicating a need for maintenance.
  • the evaluation device is provided with means for detecting the speed with which the work cycles ran and run, and with means for forming a correction signal which is dependent on these speeds and the duration of the presence of the respective speed and with which the Work cycles of the work organ representative signal or the signal representing the predetermined limit value can be corrected.
  • all movable elements reflecting the operating speed of a spinning machine are, for example ring spindles on ring spinning machines, stretching rollers on ring spinning machines or draw frames, wings or spindles on flyers, traversing thread guides on OE spinning machines, as well as ring banks on ring spinning machines, etc. see below.
  • the working cycles are thus defined as the number of revolutions for rotating elements and as corresponding periods for elements with linear motion trajectories.
  • a frequency generator (3) controls the individual motors (2), the frequency (f) applied to the individual motors (2) being permanently assigned to the speed (n spi ) of the ring spindle (4).
  • the frequency (f) generated by the frequency generator (3) is thus a measure of the spindle speed (n spi ) and thus of the working speed of the entire ring spinning machine .
  • a ring spinning machine is operated at different spinning speeds, which are then available over certain periods of time.
  • the ring spindles run, for example, for a certain period of time (t1) with a low spindle speed (n spi1 ) of 12,000 min admir1 for a period (t2) with an average spindle speed (n spi2 ) of 15,000 min ⁇ 1 and for a third period (t3) with a high spindle speed (n spi3 ) of 18,000 min ⁇ 1.
  • a maintenance interval is not simply determined via the operating time of the machine. Rather, the need for maintenance is determined, taking into account the operating conditions during the operating time.
  • the spindle speeds (n spi1 , n spi2 , n spi3 ) correspond to frequencies (f1, f2, f3) of the frequency generator (3).
  • the number of spindle revolutions results that the spindles have performed at the spindle speed (n spi ) during the time period (t).
  • a monitoring device (1) of FIG. 1, which is shown enlarged in FIG. 2, has a computer (5), to which the spindle speeds (n spi ) or the corresponding frequencies (f) plus the respective time period (t) are applied. during which the frequencies (f) are present and available be tested.
  • computer (5) the products are formed from spindle speeds (n spi ) and time period (t).
  • these products are fed to a summator (6) into which they are added up.
  • these products are fed to a computer (7) which is connected to a data input unit (11) and a data input unit (12).
  • a limit value for a certain number of spindle revolutions is entered via the data input unit (12), at which a maintenance operation is to take place.
  • This limit value is based on empirical values, with an average spindle speed being assumed, for example.
  • Exponents (p) are entered via the data input unit (11) and correct the limit value entered by the data input unit (12) in the computer (7).
  • the level of the exponents to be assigned to the limit value (p) is based on the level of the products supplied from the spindle speed and the time period. For example, a supplied product is assigned in computer (7) a specific exponent (p) which is linked to the limit value. The limit value is thus changed depending on the number and amount of the products supplied, the limit value also being assigned a high exponent for a high product.
  • the computer (7) thus acts as a limit value generator, the corrected limit value in each case being fed to a comparator (8) in which it is compared with the summed up products of the sumnator (6). If the corrected limit value and the product sum of the summator (6) match, the signal generator (10) indicates that maintenance is required.
  • the summator (6) also continues to add up if there is already a need for maintenance to indicate the extent to which the maintenance interval has been exceeded.
  • the summator (6) is only deleted during the actual maintenance process.
  • FIG. 3 shows a further embodiment of the monitoring unit (1), which is also connected to the frequency generator (3) of the individual motors (2) of the ring spinning machine.
  • the frequency (f) is determined at certain periodic time intervals ( ⁇ t) detected. These time intervals ( ⁇ t) are calculated in minutes or hours.
  • the feed frequency (f) is detected and linked in a computer (13) with an exponent (p) which determines the frequency (f) and multiplied by the time interval ( ⁇ t).
  • the exponents (p) are entered via a data input unit (11 '), which is connected to the computer (13).
  • each frequency is assigned a different exponent (p), the exponent (p) assuming values greater than 1 at higher and higher frequencies (f) and increasing with the frequency level.
  • the computer (13) is connected to a summator (14) in which the load quanta ( ⁇ b) are added up.
  • a data input unit (12 ') is connected to a comparator (8'), by means of which a predetermined limit value (B limit ), which specifies the number of spindle revolutions after which a maintenance operation is to be carried out, is entered.
  • the limit value (B limit ) is compared with the load quanta added up in the summator (14) and, if there is a match on the signal generator (10'), maintenance requirements are displayed.
  • B limit a predetermined limit value
  • the signal generator (10 ') is then a display, on which the type and / or the location of the maintenance work is then specified, the need for which was determined.
  • an exponent (p) was used to correct the maintenance intervals, which has led to an exponential dependency between maintenance intervals and working speed.
  • Other mathematical relationships are also conceivable, through which mathematical functions between working speeds, working times and predetermined limit values are achieved.
  • a proportional dependency is achieved.
