Definitions

  • the present invention relates to a method and a device for monitoring the belt tension of the drive belt of a ring spinning machine, which has a large number of spinning positions whose spindles are frictionally driven during the spinning operation by a circulating tangential belt.
  • spinning machines have been known for a long time that have a large number of spinning positions, the spindles of which are driven in a frictionally engaged manner by a rotating tangential belt.
  • Such multipoint spinning machines e.g.
  • the individual work stations are each equipped, for example, with a freely rotatably mounted spindle, with a machine-long, circulating tangential belt usually being used as the drive means for the numerous spindles.
  • the tangential belt runs over the drive wheel of a spindle drive, which is arranged approximately in the middle of the machine and is connected to a frequency converter, and is guided over a deflection roller at each corner of the textile machine.
  • the machine-long tangential belt should always have a sufficiently high belt tension, since if the belt tension is too low, there is a risk that so-called creep spindles will occur. This means that if the belt tension is too low, the contact pressure of the tangential belt, which ensures proper frictional entrainment of the spindle, is too low on the drive whorl of the spindle, with the result that the speed of these spindles falls below a specified speed level of the ring spinning machine.
  • a manually operable tensioning device in the area of the circulating tangential belt of a ring spinning machine.
  • Such manually operable tensioning devices are usually operated by the operator either whenever the operator believes that the belt tension of the tangential belt has dropped somewhat, or the tensioning device is operated routinely according to a predetermined schedule.
  • the JP S62 250231A and the CN 205 839 224 U disclose spinning machines with drive belts whose belt tension is regulated. This means the belt tension is automatically adjusted to stay within a specified range.
  • the DE 2 109 888 A1 discloses a tangential belt drive for spindles of spinning and twisting machines.
  • a pressure gauge controls a visual and/or audible alarm that alerts operators to the need to adjust the belt tension. The machine is shut down when the belt tension falls below a minimum.
  • the object of the invention is to develop a method and a device that ensures reliable monitoring of the belt tension of the machine-long tangential belt in a simple manner and makes it visible to the operating personnel during the entire operating time of a ring spinning machine.
  • the belt tension of the tangential belt is monitored by a sensor device which is connected to a machine controller of the ring spinning machine, the belt tension data determined by the sensor device being processed in the machine controller and visualized on a display and the display based on a curve shows how the belt tension has developed over a specific period of time in the past.
  • the method according to the invention not only has the advantage that the operating personnel is informed at all times about the current belt tension data of the ring spinning machine and, taking into account the information visible on the display, can ensure that the belt tension data is always kept within a definable range that is optimal for proper spinning cop production if necessary, the operating personnel can also subsequently determine at any time which belt tension data was available on the ring spinning machine at a specific point in time. This means that the operating personnel can, if there is a risk that the specified belt tension data on the ring spinning machine can no longer be maintained in the foreseeable future, because e.g. B. the tangential belt is lengthened due to age, initiate a tangential belt change in good time. In addition, if necessary, conclusions can be drawn about possibly faulty spinning cops from the belt tension data stored in the machine control.
  • the machine controller initiates a reaction when it is determined that the belt tension data of the tangential belt are in danger of reaching predefinable minimum or predefinable maximum values. This means that the machine control ensures that a warning device that the operating personnel can perceive is triggered.
  • the machine control shows e.g. B. based on an optical signal, e.g. by a relatively conspicuous flashing light, that an intervention by the operating personnel is advised.
  • the warning can also be in the form of an acoustic signal, which is also understood by the operating personnel as a sign that manual intervention should take place as quickly as possible. This means that the operating personnel are instructed by a warning signal to tighten the tangential belt a little more, for example by means of a belt tensioning device.
  • Such belt tensioning devices usually have a slidably mounted pulley that can be positioned in a defined manner either manually or by means of an electric actuator.
  • Belt tensioning devices of this type which are known per se, are characterized not only by high reliability, but also by excellent functionality.
  • the machine control automatically ensures that the ring spinning machine is automatically switched off immediately if necessary. In such a case, it is reliably ensured that the ring spinning machine is only ever operated with the correct belt tension of its tangential belt.
  • the machine controller records the belt tension data both during the spinning operation and during the doffing process of the ring spinning machine. In this way, it is easily possible for the operating personnel, if necessary, to trace back the belt tension data of the tangential belt without gaps over the entire service life of the tangential belt and, in doing so, e.g. B. can draw conclusions about the operation of subsequent tangential belts.
  • the maximum, minimum and average belt tension values of the tangential belt and the positions of the ring rail of the ring spinning machine are shown on the machine control display during the spinning operation of the ring spinning machine. This means that the operating personnel can use the belt tension values shown on the display to draw conclusions about the running behavior of the tangential belt at any time and, if necessary, to correct the belt tension immediately.
  • the ring spinning machine for carrying out the method according to the invention has a sensor device that monitors the belt tension of the tangential belt of the ring spinning machine and is connected to a machine controller of the ring spinning machine that processes the determined belt tension data and a display has, on which the belt tension data of the tangential belt can be visualized, and wherein the display has a display which shows, on the basis of a curve, how the belt tension has progressed during a certain past period of time.
  • the operating staff is informed at all times about the current belt tension data of the ring spinning machine and, taking into account the information visible on the display, can not only always immediately ensure that the belt tension data is always kept in a definable range that is optimal for proper spinning cop production, but can if there is a risk that the specified belt tension data on the ring spinning machine can no longer be maintained in the foreseeable future, e.g. B. the tangential belt is lengthened due to age, also ensure a tangential belt change in good time. Furthermore, the operating personnel can also determine retrospectively which belt tension data was available on the ring spinning machines at a certain point in time and, from this belt tension data stored in the machine control, draw conclusions about possibly faulty spinning bobbins.
  • the sensor device has a movably mounted deflection roller, which corresponds to a pressure cell. That is, during the spinning operation the movably mounted deflection roller is positioned depending on the respective belt tension of the tangential belt of the ring spinning machine, which is registered by the pressure cell and converted into corresponding signals that are forwarded to the machine control of the ring spinning machine.
  • a measured value amplifier is connected to the pressure cell and connected to the machine control of the ring spinning machine. This means that the signals initiated by the pressure cell are first processed in the measured value amplifier in such a way that the signals are forwarded to the downstream machine control of the ring spinning machine, which is equipped with a display, and can be properly processed there.
  • the belt tension values determined by the pressure cell are made visible to the operating personnel on the machine control display.
  • the 1 shows a highly schematic plan view of a ring spinning machine 1, the spindles 2 of which are driven by a rotating tangential belt 3 by friction.
  • Ring spinning machines 1 of this type have a large number of work stations on both longitudinal sides of the machine, each of which is equipped with such a spindle 2 .
  • so-called ring spinning bobbins are produced on these spindles 2, which have relatively little yarn material and are therefore wound into cross-wound bobbins in a downstream production step, on so-called cross-winding machines.
  • the spindles 2 of such ring spinning machines 1 are mounted so as to be freely rotatable and are driven by friction by the circulating tangential belt 3, which in each case acts on a drive whorl of the spindles 2.
  • so-called pressure rollers 4 are usually also provided between the spindles 2, which, preferably arranged in pairs on a spring element 19, bear with some pressure on the circulating tangential belt 3.
  • a machine-long tangential belt 3 runs during one revolution over four deflection rollers 5, each arranged at the machine corner, a drive wheel 7 arranged on the motor shaft of a spindle drive 6, and over a belt pulley 8 of a belt tensioning device 27.
  • the belt pulley 8 is linearly adjustable and can either be adjusted manually by the operator, or, as shown in the present embodiment, via an actuator 10, which is preferably designed as an electric motor drive 11.
  • the belt pulley 8 is connected to the electric motor drive 11 via a screw drive 9, for example.
  • the actuator 10 of the belt tensioning device 27 is then also connected to the machine controller 13 of the ring spinning machine 1 via a control line 20 .
  • a sensor device 12 equipped with a pressure cell 15 is also provided, which is also connected via a signal line 21 to the machine controller 13 of the ring spinning machine 1 , which, as can be seen, has a display 23 .
  • the in 1 The positioning of the sensor device 12 shown represents only one possible exemplary embodiment. This means that the sensor device 12 does not have to be, as in 1 shown, be arranged in the area of the right, upper deflection corner of the tangential belt 3, but can also be positioned in the area of one of the other deflection corners of the tangential belt 3 without any problems.
  • the sensor device 12 with which the belt tension of the tangential belt 3 is monitored, is shown on a larger scale.
  • the sensor device 12 which has a holding plate 18 and fastening devices 14, e.g. B. bolts, is connected to a (not shown) spindle bank of the ring spinning machine 1, a movably mounted deflection roller 5, which corresponds to a pressure cell 15.
  • the pressure cell 15 is connected to the machine control 13 of the ring spinning machine 1 via a signal line 21, in which a measured value amplifier 22 is switched on.
  • the deflection roller 5 is arranged on a holder 16 which in turn is mounted so that it can rotate to a limited extent about an axis 17 .
  • the deflection roller 5 is constantly acted upon by the circulating tangential belt 3, which is provided with a specific belt tension, in the direction of the pressure cell 15, which the pressure cell 15 registers and converts into corresponding electrical signals S.
  • the pressure cell 15 is designed in such a way that it registers changes in the belt tension of the tangential belt 3 immediately, regardless of the running direction of the tangential belt 3 . This means that the belt tension of the tangential belt 3 is always reliably monitored with the pressure cell 15, regardless of whether ring spinning cops are manufactured with an S or a Z twist.
  • the electrical signals S of the pressure cell 15 are first processed in the measured value amplifier 22 before they are forwarded to the machine control 13 of the ring spinning machine 1 via the signal line 21 .
  • the machine control 13 has a display 23 on which the belt tension data of the tangential belt 3 registered by the pressure cell 15 and processed in the machine control 13, as follows with reference to FIG Figures 3 , 4 and 5 explained in more detail, can be visualized in different ways.
  • a first visualization option for data is shown on the display 23 of the machine controller 13 .
  • the display 23 shows, among other things, the object used for monitoring the belt tension of the tangential belt 3.
  • z. B an image of the sensor device 12 is shown.
  • On the left are various, e.g. B.
  • Setting values of the tangential belt 3 relevant digital displays 40 - 43 are shown, while on the right digital displays 44 - 47 are shown which relate to the limit values of the belt tension.
  • a bar chart 24 is shown, which is divided into different measuring ranges 28 - 32 , one above the other in the present exemplary embodiment, which relate to the belt tension of the tangential belt 3 .
  • belt tension values are documented that are clearly too high, i.e. belt tension values which, when reached, the machine control 13 immediately switches off the ring spinning machine 1, e.g. also to avoid consequential damage.
  • the measurement area below it, marked 29, represents a so-called warning area.
  • the belt tension values listed in measurement area 29 are also somewhat too high.
  • the machine control 13 of the ring spinning machine 1 triggers an alarm when the belt tension values fall within this measuring range 29 .
  • the middle measurement area 30 shows proper belt tension values, that is, belt tension values that the tangential belt 3 should have during the spinning operation.
  • the measuring area 31 below represents a warning area again.
  • the belt tension values listed in measuring area 31 are a bit too low.
  • the machine control 13 of the ring spinning machine 1 therefore triggers an alarm if the belt tension values fall within the measuring range 31 .
  • the lower end of the bar graph 24 is formed by the measuring range 32, which shows significantly lower belt tension values, ie belt tension values at which proper operation of the ring spinning machine 1 is no longer possible.
  • the machine control 13 therefore switches the ring spinning machine 1 off immediately.
  • the display 40 shown on the left-hand side of the display shows the instantaneous belt tension value in digital form, shown analogously on the bar graph 24 using the arrow 25 .
  • the display 41 uses a curve to show how the belt tension has progressed over a specific past period of time.
  • the digital displays 42, 43 each reveal an advantageous correction factor or indicate a specific calibration value.
  • the digital displays 44-47 shown in the area of the bar graph 24 show various limit values of the belt tension of the tangential belt 3, ie belt tension values at which a specific reaction of the machine control 13 takes place.
  • the Figures 4 and 5 disclose further visualization possibilities of the display 23 of the machine control 13.
  • the 4 shows the display 23 with the depiction of a diagram 33 on which the course of various belt tension values of the tangential belt 3 is illustrated over a specific period of time during the spinning process.
  • the diagram 33 has a horizontally arranged X-axis and a vertically arranged Y-axis.
  • the X-axis shows the chronological sequence of the spinning process in days, while the vertical Y-axis shows the belt tension values of the tangential belt 3 in N and the height of the ring rail of the ring spinning machine 1 in mm.
  • the curve 34 marked with the reference number 34 reveals the profile of the respective maximum belt tension values, while the curve 35 shows the profile of the respective minimum belt tension values of the tangential belt 3 .
  • the curve 36 shows the progression of the mean belt tension values of the tangential belt 3 in each case.
  • the curve 37 also shows the progression of the positions of the ring rail of the ring spinning machine 1 during the spinning process.
