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 plurality of spinning stations, the spindles of which are frictionally driven by a rotating tangential belt during the spinning operation.
Such multi-point spinning machines for example, ring spinning machines, generally have a plurality of identical jobs, which are arranged side by side on both sides of the machine longitudinal axis and their working organs are driven together by machine-length, continuous Endloszugstoff.
the individual jobs are, for example, each equipped with a freely rotatably mounted spindle, as a drive means for the numerous spindles usually a machine-long, circumferential tangential belt is used.
the tangential belt runs over the drive wheel of an eg. Machine centrally arranged, connected to a frequency converter spindle drive and is guided at the corners of the textile machine in each case via a pulley.
the machine-length tangential belt should, for example, always have a sufficiently high belt tension, because if the belt tension is too low, there is a risk of so-called dobby spindles occurring. That is, if the belt tension is too low, the abutment pressure of the tangential belt, which provides for proper frictional entrainment of the spindle, is too low at the drive whirl of the spindle, with the result that the speed of these spindles falls below a predetermined speed level of the ring spinning machine.
a manually operated clamping device in the area of the rotating tangential belt of a ring spinning machine.
Such manually operable jigs are usually operated by the operator either whenever the operator considers that the belt tension of the tangential belt has dropped somewhat, or the jig is operated routinely according to a predetermined schedule.
the patent does not contain any indications as to whether the determined warp tension values are in any way made visible to the operating personnel.
the work stations are assigned signalers that emit appropriate error signals when errors occur.
the signal transmitters are connected to the machine control of the spinning machines, which has a display device which is connected to a so-called error signal evaluation device.
the error signal evaluation device initiates, depending on the error signal, a specific control process, for example a regular shutdown program of the spinning machine or an emergency shutdown program.
the present invention seeks to develop a method and a device that ensures the reliable monitoring of the belt tension of the machine-long tangential belt during the entire operating time of a ring spinning machine in a simple manner and makes it visible to the operator.
This object is achieved in that the monitoring of the belt tension of the tangential by a sensor device which is connected to a machine control of the ring spinning machine, wherein the determined by the sensor device belt tension data processed in the machine control and visualized via a display.
the method according to the invention not only has the advantage that the operating personnel are informed at all times about the instantaneous belt tension data of the ring spinning machine and, taking account of the display visible on the display, can ensure that the belt tension data is always kept within a predefinable range which is optimal for proper spinning cop production If necessary, the operating personnel can at any time subsequently determine which belt tension data were present at the ring spinning machines at a specific point in time. That is, 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 z. B. the Tangentialriemen is age-related, in time to initiate a Tangentialriemen grill. In addition, if necessary from the belt tension data stored in the machine control, conclusions can also be drawn about any defective spinning cops.
the machine control when it is determined that the belt tension data of the tangential belt threaten to reach predetermined minimum or predefinable maximum values, initiates a reaction. That is, the machine control ensures that a perceptible for the operator warning device is triggered.
the machine control z. B. on the basis of an optical signal, for example.
an optical signal for example.
the warning can also be in the form of an acoustic signal, which is also understood by the operator as a sign that a manual intervention should be done as quickly as possible. That is, the operator is stopped by a warning signal, the tangential belt, for example. By means of a belt tensioning device to stretch a little more.
Such belt tensioners usually have a slidably mounted pulley, which can be positioned either manually or by means of an electric actuator defined.
Such, known per se belt tensioning device are characterized not only by a high reliability, but also by an excellent functionality.
the machine control system 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 always operated only with a proper belt tension of its tangential belt.
the machine control 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 that the operator if necessary, trace the belt tension data of the tangential seamlessly over its entire life of the tangential and thereby z. B. draw conclusions on the operation of subsequent tangential belt.
the device for carrying out the method according to the invention has a sensor device which monitors the belt tension of the tangential belt of the ring spinning machine and is connected to a machine control of the ring spinning machine, which processes the belt tension data determined and has a display on which the belt tension data of the tangential belt can be visualized.
the sensor device has a movably mounted deflection roller which corresponds to a pressure measuring cell. That is, during the spinning operation the movably mounted deflection roller is positioned as a function of 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, which are forwarded to the machine control of the ring spinning machine.
a measuring amplifier is connected to the pressure cell and this connected to the machine control of the ring spinning machine. This means that the signals initiated by the pressure cell are initially processed in the measured value amplifier in such a way that the signals can be forwarded to the downstream machine control of the ring spinning machine equipped with a display and processed properly there. On the display of the machine control system, the belt tension values determined by the load cell are made visible to the operating personnel.
the Fig. 1 shows in plan view, very schematically, a ring spinning machine 1, the spindles 2 are frictionally driven by a rotating tangential belt 3.
Such ring spinning machines 1 have on both longitudinal sides of the machine a plurality of jobs, which are each equipped with such a spindle 2.
so-called ring spinning cops are produced, which have relatively little yarn material and are therefore wound in a downstream production process, on so-called cross-winding machines, into cross-wound bobbins.
the spindles 2 such ring spinning machines 1 are freely rotatably mounted and are frictionally driven by the rotating tangential belt 3, each of which acts on a Antriebswirtel the spindles 2.
so-called pressure rollers 4 are usually provided between the spindles 2, which preferably arranged in pairs on a spring element 19, with some pressure on the rotating tangential 3.
a machine-long tangential 3 runs during a cycle on four, each machine corner arranged pulleys 5, arranged on the motor shaft of a spindle drive 6 drive wheel 7 and a pulley 8 a belt tensioning device 27.
the pulley 8 is mounted 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 pulley 8 is, for example, connected via a screw drive 9 to the electric motor drive 11.
the actuator 10 of the belt tensioning device 27 is then also connected in such a case via a control line 20 to the machine control 13 of the ring spinning machine 1.
a sensor device 12 equipped with a pressure measuring cell 15 is furthermore provided, which is likewise connected to the machine control 13 of the ring spinning machine 1 via a signal line 21, which, as can be seen, has a display 23.
Fig. 1 shown positioning of the sensor device 12 is only one possible embodiment. That is, the sensor device 12 by no means, as in Fig. 1 can be arranged in the region of the right upper Umlenkecke the tangential 3, but can also be easily positioned in the region of one of the other Umlenkecken the tangential 3.
Fig. 2 is the sensor device 12, with which the belt tension of the tangential belt 3 is monitored, on a larger scale.
the sensor device 12 via a holding plate 18 and fastening means 14, z. B. bolts, is connected to a (not shown) spindle bank of the ring spinning machine 1, a movably mounted guide 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 turned on.
the deflection roller 5 is arranged on a holder 16, which in turn is limited rotatably mounted about an axis 17.
the guide roller 5 is constantly acted upon by the rotating, provided with a certain belt tension tangential 3 in the direction of the pressure cell 15, which registers the pressure cell 15 and converts into corresponding electrical signals S.
the pressure cell 15 is designed so that it, regardless of the direction of the tangential belt 3, registered changes in the belt tension of the tangential 3 immediately. That is, with the pressure cell 15, the belt tension of the tangential belt 3 is always reliably monitored regardless of whether ring spinning cops are made with S or Z rotation.
the electrical signals S of the pressure cell 15 are first processed in the measured value amplifier 22, before they are forwarded via the signal line 21 to the machine control 13 of the ring spinning machine 1.
the machine controller 13 has a display 23 on which the registered by the load cell 15 and processed in the machine control 13 belt tension data of the tangential belt 3, as described below with reference to Figures 3 . 4 and 5 explained in more detail, visualized in different ways.
a first visualization option of data on the display 23 of the machine controller 13 is shown.
the display 23 shows, inter alia, the object used to monitor the belt tension of the tangential belt 3.
an image of the sensor device 12 is shown in the middle of the display z.
On the left side are different, z.
setting values of the tangential belt 3 are shown in relation to digital displays 40-43, while digital displays 44-47, which concern the limit values of the belt tension, are shown on the right.
a bar diagram 24 is shown, which is divided into different, in the present exemplary embodiment, five superimposed measuring ranges 28 - 32, which relate to the belt tension of the tangential belt 3.
belt tension values which, when reached, the machine controller 13 immediately deactivates the ring spinning machine 1, for example also to avoid consequential damage, are documented in the upper measuring range denoted by reference numeral 28.
the underlying measuring range marked 29 represents a so-called warning range. Also the belt tension values listed in measuring range 29 are a bit too high. The machine control 13 of the ring spinning machine 1 triggers alarm when the belt tension values fall into this measuring range 29.
the middle measurement range 30 shows proper belt tension values, that is, belt tension values that the tangential belt 3 should have during spinning operation.
the underlying measuring range 31 again represents a warning range.
the belt tension values listed in the measuring range 31 are somewhat too low.
the machine control 13 of the ring spinning machine 1 therefore triggers an alarm when the belt tension values fall into the measuring range 31.
the lower end of the bar graph 24 is formed by the measuring area 32, which still shows significantly lower belt tension values, that is, belt tension values at which proper operation of the ring spinning machine 1 is no longer possible in any case. Upon reaching the measuring range 32, the machine control 13 therefore switches off the ring spinning machine 1 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 chart 24 with reference to the arrow 25.
the display 41 shows by means of a curve how the belt tension has run during a certain, 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, as already indicated above, various limit values of the belt tension of the tangential belt 3, that is, belt tension values at which a specific reaction of the machine control 13 takes place.
the 4 and 5 reveal further visualization possibilities of the display 23 of the machine control 13.
the Fig. 4 shows the display 23 with the representation of a diagram 33, on which the course of different belt tension values of the tangential belt 3 is clarified during the spinning process over a certain period of time.
the diagram 33 has a horizontal X-axis and a vertically arranged Y-axis.
the time sequence of the spinning process in days is shown on the X axis, while the values of the belt tensions of the tangential belt 3 in N and the height of the ring rail of the ring spinning machine 1 in mm are indicated on the vertical Y axis.
the curve 34 identified by the reference numeral 34 reveals the profile of the respective maximum belt tension values, while the curve 35 illustrates the course of the respective minimum belt tension values of the tangential belt 3.
Curve 36 accordingly shows the progression of the mean belt tension values of tangential belt 3.
Curve 37 also shows the course of the positions of the ring rail of ring spinning machine 1 during the spinning process.
the Fig. 5 shows the display 23 with the representation of a diagram 33, on which the course of the belt tension during a Doffvorganges the ring spinning machine 1 is illustrated.
the diagram 33 has a horizontal X-axis and a vertically arranged Y-axis.
On the X-axis is the time sequence of a Doffvorganges in min. while the values of the belt tensions are displayed in N on the vertical Y axis.
the curve 34 shows the course of the belt tension values during a doffing process.
