Description
Technical field
The present invention relates to a kind of weaving loom, especially a kind of carding machine, drawing frame or combing machine, at least comprise two motorized motions, their rotating speed is coordinated mutually in this function aspects of main functionality of driving device parts especially fibrous material drafting unit, measurement component, transmission part and/or memory unit, has a measurement mechanism that is used for the actual value of definite driving and/or fibrous material correlation measure at least.
Background technology
In textile industry, disperse to drive or utilizing of single driving known for everyonely had for a long time.For example disclose drafting system that a kind of dependence has the paired roller that can be regulated by frequency divider by the rotation speed ratio of independent electrical motor driven among DE 29 41 612 C2 and merged drawing frame with the drawn fiber bar.The fibre weight of the ribbon that continuous calculating of CPU is passed through also shows the rolling target speed that different rollers are right.The same with other known weaving loom that single driving is arranged in this machine, master-slave principle is employed.Term " single driving " is understood that here several drivings are provided, and each in them drives one or several axle.According to master-slave principle, the motor reel of a reality is restricted to main shaft, and the axle of other motorized motions is being followed the determined rotation speed ratio of main shaft thus.Alternatively, the main shaft of a void is provided to produce desired value, this desired value and theoretic desirable form without any deviation.On-stream, all from the clock signal of axle by empty main shaft synchronous with one scan moment.Real main shaft the same with empty main shaft between on-stream period in the inquiry of the time interval of rule from driving (so-called poll), resulting thus data are transmitted by bus line as a rule.
Shortcoming in these weaving looms is that the utilization of known master-slave principle can not guarantee that all drivings are each other with the run-in synchronism of the best.
Summary of the invention
The objective of the invention is to improve the weaving loom that utilizes several drivings and especially have the drawing-off precision in the spinning machine of drafting system.
This purpose is reached in the weaving loom of the type that beginning is mentioned, by change main at least one control and/or the regulon that drives function by the actual value effect.
Advantage of the present invention in fact especially is the suitable design of machine, can change in main functionality under the function of precondition.Thereby might the function of tonic chord be assigned to one or several driving at once by (at least one) control and/or regulon.Empty main shaft also can be at interval the speed of demonstration motor.This may cause different drivings the different time as main shaft.Therefore the function of tonic chord can rely on current main form to be transmitted, and also might be transferred to virtual main shaft.
Actual value is preferably to be transferred to central authorities or to evacuate the control and/or the regulon of design, and at this moment it determine main shaft based on these values.This unit is the corresponding new rolling target speed that drives of indication easily also, can consider to take the parameter of adding if desired.Have in the weaving loom of regulating drafting system at one, about the measured value of strip cross section, the especially calculating of the rolling target speed that produces from drafting system.On the one hand being determining of main functionality, is that the indication of new rolling target speed may be distributed by plurality of units on the other hand.
Most of ground preferably are each supposes the role that the most weak current driving is a main shaft in order to avoid surpass load powered, or under the situation of regulating drawing frame, realizes continuous good bar protonatomic mass.
May be that fix or variable limit value advantageously to several or all measurement mechanism regulations, be higher or lower than this limit value, obtain the actual value (or be derived from these actual values or by the pretreated signal of these actual values) of moment according to the control of the present invention operation and/or regulon from corresponding measurement mechanism.Thus, rolling target speed is used for other immediately and drive calculates (at the drawing frame of an adjusting especially when considering the cross section fluctuation of current strip) and be transferred to these drivings.
The indication of limit value is useful because for instance, when measure current as driven motor current draw in the practical range of values of certain driving function, there is no need it is changed to main the driving.Have only the current drain when the measurement component that drives signal to surpass when using limit value, this driving can not be satisfied current needs, can own subsequently imitation to such an extent as to therefore receive other driving of the function of tonic chord effectively.
According to the present invention, preferably, fixing inquiry and the irregular inquiry relevant with control recited above and/or regulon is not performed.As long as in the principal and subordinate distributes, do not need to change, that is to say, as long as current principal and subordinate distributes the needs that satisfy when front wheel driving, be exactly unnecessary by control and/or the such inquiry of regulon.When currency exceeded the scope of predetermined value, the current actual value of measured unit record (may prepare after) preferably only was transmitted.
Yet such situation also is possible, wherein, actual value by one, several or all constant transmission of measurement mechanism so that controlled and/or regulon consider.By this way, for example a kind of known basis is structured in the functional distribution of main driving and assists.
Actual value (or deriving from signal) is transferred to determines that the main different measured value that drives functional control and/or regulon can be measured by suitable measurement mechanism.Like this, the measurement mechanism of measurement that is used for the change of the rotating speed of driving shaft or rotating speed is provided especially.As selecting or in addition, the temperature of the phase transition of rotating torque, drive electric motor electric current, driving and/or phase angle, rotating speed or their in good time derivation and motor also can be measured.As selecting or in addition, such as thick point and/or fibrous material performance are measured by measurement mechanism or sensor.For example, if about the fiber skein cross section (term of fiber skein quality, fiber skein thickness or fiber skein volume also are known) scanning roller signal measured, signal can be used to scan roller to determine empty main shaft under the situation of the very big point of thickness, and it can be integral and cause entire machine to turn round to guarantee stretching accurately under lower transmission speed with slower speed with control and/or regulon.Also might measure drafting force drafted on the fiber skein.Summarize, be merely able to measured about driving or fibrous material or stretching actual as measured value.
All be implemented by the present invention about all big flexibilities that drive, because with respect to prior art, constant does not rely on same main the driving or empty main the driving from driving.The present invention may realize the adjusting of the desired value that determines with the isopleth error, and thus, main drive controlling function can be converted along with situation.This for example takes place in a preferred embodiment, and the conversion master is driven into current especially weak driving.
The present invention can be applied to weaving loom, especially has the spinning machine of drafting system, wherein has at least two drivings to be provided.These drive independent or several parts.Such driving especially can be provided for drawing frame, give the traction roller of drafting system input, the input roller of drafting system, central authorities' roller and/or output or transmission roller, the traction roller that is used for drafting system output place, be used for the rotating disc that install bar tube top, and be used to rotate or the supporting surface of the memory stick tube that traverses to fill.Mentioned above considering, above several parts of being mentioned also can be by an independent Motor Drive.Motor can be used to such as delivery roller to and calender roller to the downstream of (traction roller to).Second motor can drive a pair of scanning roller and a pair of delivery roller and a pair of central roller that is positioned at the upstream of aforesaid drafting system.Three-motor can be as traction drive, and this driving is particularly useful for drawing strip from the bar tube thus.The moving rotating disc that drives of 4 wheel driven, for example, and the supporting surface of bar tube.The different variation of this design is possible.
In regulating drawing frame, advantageously, the value of the strip cross section of being surveyed before the drafting system is transferred to an adjusting calculator, and its calculating is used for setting value or the desired value that drafting system drives.According to the present invention, these desired values then are transferred to be controlled and/or regulon, and it is regulated these rolling target speed and transmit the rolling target speed that may revise according to current actual value (just current main the driving) and arrives this driving if desired.Here control and/or regulon supposition is synchronous with driving.Rely on design, also can during regulating calculator, take place based on the adjusting of strip fluctuation from the rolling target speed of calculated with actual values.
Operation according to control of the present invention and/or regulon can be designed to a central location.Depend on the actual value of one or several measurement mechanism that is provided to central authorities control and/or regulon, when considering that when being used for setting value that drafting system drives or desired value, the desired value of all drivings is determined and is assigned to all drivings.
As selecting or in addition, an independent driving or each driving can be assigned with control and/or regulon, also under the appointment of " action control ", preferablyly be designed to a storage programming Control (SPS).Store the actual value that programming Control is responsible for receiving the different measuring device for one in the preferred case, the calculating of new actual speed desired value is based on the rotating speed desired value of being calculated by the adjusting calculator that is used for the drafting system driving and be used for transmitting to corresponding driving.The differentiation of these functions also can be provided in several Control.Also might be used for receiving and computing function and one transfer function being passed to other storage programming Control.In a variation, central authorities control and/or regulon can transmit these tasks to the control and/or the regulon that are assigned to other driving with flexible way.All designs of mentioning increase diversity and independently control and/or regulate responsibility.
In an advantageous embodiments, at least one control and/or regulon can limit the new rolling target speed of all drivings, comprise current main the driving, surpass instantaneous required degree, machine can temporarily or with lower power be driven for a long time like this.This situation can be explained in framework of the present invention that the most weak current driving is temporary transient to be driven as main, and other driving must be followed.If rotating speed further reduces, the main function that drives can be taken over by main driving of void.The duration of low power can be followed the current minimum driving degree that for example overloads.The power of machine is quite high when the rolling target speed of all drivings is adjusted on the contrary, and like this, the transmission speed of leaving drawing frame of ribbon often changes, but the result is a high yield.
In the preferred embodiment, be connected generation by bus between the independent driving and/or with contact between central authorities control and/or the adjustment unit.In this case, advantageously, use parallel or continuous bus system, serial bus, side are propped up bus or contact bus.As selection, the independent connection between measurement mechanism and at least one control and/or the regulon is provided, and these can be made into the form of numeral or simulation pipeline.
Below, the example of several application of the present invention will be presented.For example, if the stable loading of limit value of drive electric motor electric current or driving shaft limits reach, this driving can be born the main function that drives, so other rotating speed will be coordinated mutually with described qualification.Suppose that a motor overload or mechanical axis overload, this drives preferably bears the main function that drives, so remaining driving reduces for the synchronous possibility according to them that keeps rotating speed.Suppose power failure and cause the machine costing, the change that main driving can be further different several times, thus, this change is advantageously kept to determine by the energy of the part of drive machines separately.
Further advantageously, if drive functional assignment and occur in and start and/or when stopping machine according to the present invention is main.For example, one in the driving can be designated as the main function that drives, when machine reaches the transmission speed of given drawn fiber strip or reaches predetermined current by this driving running when consuming, thus in normal operation thereafter, surrender main drive functional to another driving or empty main the driving.
In the example of Another application, weaving loom by two connect in succession machine module form, it is set up separately or is combined in the frame, such as carding machine and drawing frame.In this case, functional can the driving from an of module of main driving changes the not driving of another module.In the example of carding machine and drawing frame combination, suppose to arrive the velocity perturbation of fiber skein of the transmission of the fibrous material of combing input or combing output place, mainly drive the functional subordinate that can be assigned to combing output place of carding machine and drive.
Advantageously, the user can change and drives or the empty main main time that drives function of bearing that drives.This especially can be by specifying the described actual value that is used for measurement mechanism the qualification or the limiting value of transmission realize.Advantageously, can be when when some actual value reaches, reaching such as a transmission speed of drawing frame one by one the master drive changing function and specify operation process.
Further preferred current main the driving is shown to the user on an optical pickups.
The present invention further favourable development is to be described by dependent claims.

Fig. 1 shows the schematic side view of adjustable drawing frame of first embodiment;
Fig. 2 shows the schematic side view of adjustable drawing frame of second embodiment;
Fig. 3 shows the schematic side view of adjustable drawing frame of the 3rd embodiment.
The specific embodiment
Fig. 1 shows adjustable side view as the drawing frame of the drafting system 2 of the example of weaving loom according to the present invention that has, and drafting system comprises a pair of input roller 6, a pair of center roller 7, and a pair of delivery roller 8.The upstream of drafting system 2 is a pair of being used for from the traction roller 3 of unshowned tube traction one or a few ribbon of traction (FB) here.The strip transvers section measuring device 5 that the upstream has an a pair of scanning roller form of collection funnel 4 is installed in drafting system 2 and traction roller between 3, and the signal about the cross section of at least one one ribbon (FB) is provided.It also is possible replacing other transvers section measuring device 5 of a pair of scanning roller, for instance, and microwave acoustic resonator, capacitance sensor, ultrasonic sensor or the like.Ribbon (FB) is drafted under the effect of roller to 6,7,8 different rotating speeds in known manner.The center roller to 7 and delivery roller to 8 between, pressure rod 9 is provided for the guiding that improves the fiber that floats.After delivery roller and then is to 8 is a deflection roller 10, it makes a pair of calender roller 12 of the fiber web deflection of drawing-off towards fiber web guiding device 11 and downstream, its compacting fiber net is to ribbon, it can be by the design while is used to control the cross section of final ribbon (FB) as the measurement mechanism 12 of a cross section in known manner.As selection, other measuring method microwave, electric capacity or the like can be used.Ribbon (FB) then is directed in the bar subchannel of rotating disc 13 of rotation, and places the bar tube 14 on the bar tube stayed surface 15 of also rotation to pile up with annular one.As selection, ribbon (FB) can be stacked on and can come and go in the rectangular strip tube that moves front and back.
To the roller 3a below 3, an independent driving 30 is provided for traction roller, and it comprises an adjuster 31, a motor 32 and an analog or digital actual value indicator 33 (such as a tachogenerator).Another driving 40 that contains adjuster 41, motor 42 and actual value indicator 43 (such as a tachogenerator) be used to the driven sweep roller to 5 and the input roller to the center roller to following roller 6a, 7a.The driving (not shown) of top roller separately also is possible certainly.In this embodiment, the input roller to 6 and the preliminary drawing-off zone of center roller between to 7 set up a constant preliminary stretching.Containing the 3rd of adjuster 51, motor 52 and actual value indicator 53 (such as a tachogenerator) drives 50 and is provided for and drives the right bottom roll 8a of delivery roller and calender roller to 12.The 4 wheel driven moving 60 that contains adjuster 61, motor 62 and actual value indicator 63 (such as a tachogenerator) at last drives rotating disk 13 and bar tube supporting surface 15.
32, the regulating circuit that all passes through a sealing of each motor in 42,52,62 is regulated.The desired value of the current measured value of motor and the transvers section measuring device before drafting system 25 determines based on the cross section desired destination value of the ribbon of drawing-off that at first this value is transferred to adjusting computer 18 by conduit 22.Consider the running time of ribbon from the measurement point to the drawing point, in the function in present technique field, regulate computer 18 then calculate draft device motor 42 and/or 52 desired value.By conduit 27, utilize signal to be transferred to adjusting computer (18) by the transmission of cross section monitoring device, the quality of final ribbon can be determined and show.
For clear, several common known machine units for example machine center, maintenance unit, visualization (panel etc.) at Fig. 1 or other is not shown.
In framework of the present invention, actual value indicator 33,43,53,63 with the signal of a corresponding rotary electric motor speed not only be delivered to attached adjuster 31,41,51,61 also by bus 70 to central authorities' control and/or regulon 19, it is combined into a unit 20 in the illustrated embodiment.One of determine driving in 30,40,50,60 based on these signals of control and/or regulon 19 is main the driving, and other driving is as from driving thus.As selection, the main driving of a void can designatedly be used for the intermediate specification of rolling target speed.Main drive functional can be transmitted before and after in driving 30,40,50,60 and possible virtual main drivings by control and/or regulon 19.
In the embodiment shown in fig. 1, control and/or regulon 19 are handled the desired value that is used for drafting system driving 40 and/or 50 that adjusting calculator 18 calculated on the one hand, also handle the actual value of actual value indicator 33,43,53,63 on the other hand and think that driving 32,42,52,62 specifies the rolling target value---and may be according to current main driving modification.In an alternate embodiments, the actual value of actual value indicator 33,43,53,63 is transferred to adjusting calculator 18 (seeing the double-head arrow of regulating between calculator 18 and the unit 19) and is used at that by control and/or regulon 19, with the measured value of transvers section measuring device 5, the rolling target speed of calculating motor 32,42,52,62.Control and/or regulon 19 also can transmit mainly short message based on actual value to regulating calculator 18, such as the truth of entire machine, such as because the excess load of motor (current main the driving) can only be received a new signal up to regulating calculator 18 by control and/or regulon 19 with 80% running of the transmission speed set.The calculating of the rolling target speed of motor 32,42,52,62 actual appointments is then stayed fully regulates calculator 18, and control and/or regulon 19 are at first served so that drive 30,40 thus, and 50,60 is synchronous.
A specific driving routine business moves as main the driving, thisly under special operating condition thus functionally can be passed to other in driving, thus former main just drive as from drive and afterwards normal running be used as main the driving again.
Advantageously, the actual value corresponding to the voltage signal of motor speed is not to be transferred to control and/or regulon 19 by the constant actual value indicator that passes through.Have only when being below or above the predetermined limit definite value of these signals, above-mentioned actual value is the unit 19 that is transferred to preferably.If for example motor is not because overload reaches the indicated predetermined target velocity of control and/or regulon 19, current rotating speed is transferred to unit 19 by bus 70.Unit 19 reacts and further handles the rolling target speed that adjusting calculator 18 calculated to all drivings 30,40,50,60, especially reduces by suitable mode, specifies them by bus 70 for these drive.
For example, if find the motor overload, thereby the rolling target speed of motor 32,42,52,62 can be reduced, and high-quality like this fiber skein still can be obtained.If for example relatively poor relatively fiber skein quality is recorded, machine also can be with the running of lower speed, perhaps for output, rotating speed do not have or almost undiminished situation under accept the fiber skein quality of this difference.
Machine may be with high power or low power running in this connection.In the previous case, the current main current actual value that drives is considered, yet under second kind of situation, rotating speed is reduced when exceeding the scope of current needs.The driving that overloads under latter event is at first considered, drives as the main of void subsequently before control and/or regulon 19, and reduces the long-time effective level of rolling target speed to an appointment, and it is lower than about the actual required scope of moment overload.
Rely on actual value also might provide complete closing machine.
In the embodiment shown in fig. 1, all driving 30,40,50,60 has the measurement mechanism of actual value indicator 33,43,53,63 forms.In other design, have only one or some drivings to be assigned with and to transmit the measurement mechanism of actual value to control and/or regulon 19.This recognizes that advantageously its bigger possibility that departs from normal running of this driving is relatively large, and like this, if desired, main driving is functional can be passed to these drivings.
Replace or remove rotary electric motor speed (such as surveying by tachogenerator) or the equivalent amount, actual value can be used to distribute outside main driving functional or equal quantity except other measured value.Preferably, the current consumption of one or several in the motor 32,42,52,62 is measured by suitable measurement component, and this measurement component may be integral with corresponding adjuster 31,41,51,61.When reaching overload restriction or limit restriction for one in the motor 32,42,52,62, it can be used as main the driving.
Replace suitably the bus 70 parallel or continuous buses of design, serial bus, side is propped up bus, contact bus etc., the connection of analog or digital signal also can be used between different measurement mechanisms and control and/or the regulon 19.Figure 2 illustrates such situation.The calculating of rotating speed of target is based on the measured value of strip transvers section measuring device 5 that rely on to regulate calculator 18, and based on do not change by embodiment with respect to Fig. 1 the quality-monitoring of transvers section measuring device 12.
The embodiment of Fig. 2 further points out: the measurement mechanism of record different measuring is assigned to four each that drive in 30,40,50,60.Temperature sensor 34 is measured the temperature of the motor 32 of first driving 30 and is also passed through line 21 transmission---with analog or digital form---to controlling and/or regulon 19.In the selectable variable of this embodiment, a limit value can be pointed out when being lower than this limit value, do not have temperature value to be transferred to unit 19.If for example motor 32 overheats, unit 19 drives function to driving 30 based on the information distribution master who receives, when considering the fluctuation of strip cross section, give all drivings 30,40,50,60 regulations new target velocity, give the less pressure of motor like this and make its operating temperature descend, may distribute the main function that drives to another driving in case normal situation is rebuilt.
Among the embodiment according to Fig. 2, signal can further be used to determine current main the driving by line 22a from the signal that strip transvers section measuring device 5 is transferred to unit 19.For instance, if to such an extent as to can not evenly stretch by best quilt in the several quite thick normal speed runnings of somes quilt record in succession at drafting system 2 before the device, the main driving of a void can cause entire machine with a lower speed running.The main driving of this void is preferably to be realized in the situation of central authorities' control and/or regulon 19.
Pressure rod 9 among the embodiment of Fig. 2 is manufactured with known drafting force measurement component form, and it uses signal to control and/or regulon 19 by line 23 transmission.These signals also can be used to the interim main distribution that drives.
In addition, being used to measure the 3rd measurement component 54 that drives the power consumption of 50 motor 52 is provided, for instance, can arrive control and/or regulon 19 by the signal that line 24 transmission are correlated with when excessive overload, control and/or regulon 19 then work and assign main driving of driving 50 conducts.
At last, among the embodiment according to Fig. 2, actual value indicator 63 is measured the rotating speed of engines 62, and by line 25 serially or the actual value that transmission is relevant when the limiting value that is below or above regulation or the limit value that can be prescribed to controlling and/or regulon 19.
Opposite with the embodiment of Fig. 1, be not provided among the embodiment of Fig. 2 and bus from control and/or regulon 19 transmission signals.
Among Fig. 2, in order to prove the various possible excursion of circuit, the actual value of actual value indicator 63 can be transferred to control and/or regulon 19 or the selectable or additional direct line 26 that passes through by adjuster 61 and be shown in broken lines.
In order to illustrate, the measurement mechanism 34,5,9,54,63 of the embodiment shown in Fig. 2 is selected so that difference mutually.In the measurement mechanism some are assigned to specific driving ( measurement mechanism 34,54,63), and other (measurement mechanism 5,9) then is independent of them.Only determine that the actual value (see figure 1) relevant with one or two measured value is definitely possible, for instance, the just energy consumption of one or several in the motor.Be used to change the main measurement mechanism that drives functional distribution if only provide one, its actual value can be used to the main interim appointment that drives.When in a single day actual value drops under the limit value, can bear the main function that drives again with driving or a virtual main driving that standard mode is default.
Usually, in normal drafting system operation, be favourable if there is an interim unusual or interference need change main drive functional by the transmission of disturbing the actual value that produces.
Replace the central authorities' control and/or the regulon 19 that provide among the embodiment of Fig. 1 and 2 for example, control and/or the function of regulating also can be arranged in driving 30,40,50,60 one.Such situation has been shown among Fig. 3.According to this embodiment, drive each adjuster 131,141,151,161 designated conduct control and/or regulon of 30,40,50,60, preferably to store the form of programming Control (SPS).Independent control and/or regulon 131,141,151,161 are connected by bus system 170 each other, and stable execution control preferably and/or any task of regulating.Control and/or adjusting are transferred in control and/or the regulon 131,141,151,161 usually.If control and/or the functional of adjusting are failed in relevant driving, advantageously, this function can be by an adapter in other control and/or the regulon 131,141,151,161.
The measured value of transvers section measuring device 5,12 is sequentially transferred to regulates calculator (18).Regulate calculator 18 and link to each other with bus 170 and transmit drafting system and drive 40 and/or 60 desired value (rolling target value) to control and/or the regulon 131,141,151 or 161 being responsible for control and/or regulating, it considers that according to selected main the driving these desired values indicate rolling target speed to all drivings.
Among the embodiment according to Fig. 3, attached control and/or regulon 131,141,151 or 161 also can be supposed the main function that drives of an interim void.
According to the different embodiment of Fig. 1 to 3, the task of control that might be different and/or regulon 19,131,141,151,161 is assigned with between different unit.Thereby the actual value from measurement mechanism can be transferred to first module, and main driving can be specified by Unit second, and the new target velocity of different driving can be specified by Unit the 3rd." control and/or the regulon " mentioned no matter where, and such task distributes to fall within the scope of the invention.
The present invention is not limited to described specific embodiment.Different variations also is possible.For example, there is no need all drivings of spinning machine and all be designed to bear the main function that drives.And the distribution of the driving among Fig. 1 to 3 also is an example.The driving of different arrangements and/or different quantity also is possible certainly.
The present invention not only can make to drive and keep synchronously.Because other deceleration can take place in the peak value of seldom expection, peak value operation and shaft-driven operation maintenance are lowered.
The present invention can be used in a lot of textile machineries usually.It may comprise ungoverned drafting system in drawing frame.
