Description
Technical field
The present invention relates to a kind of technology, band with the unit length of determining the yarn band (Faserband) on the spinning preparation machine (spinnereivorberitungsm-aschine) is heavy, a section (Strecke) particularly, wherein the yarn band is unfolded (abgelegt) after leaving spinning preparation machine, and corresponding spinning preparation machine has the outlet of at least one yarn band and the control device of a control spinning preparation machine.
Background technology
Spinning preparation machine, particularly section is installed in other (machines), so that yarn band as far as possible uniformly to be provided from the textile raw material that provides before.Usually has a most adjustable drafting system for this purpose spinning preparation machine, the textile raw material that this drafting system provides before being used to stretch.For this reason, this drafting system self has row's stretching utensil, for example has the right shape of a plurality of continuously arranged cylinders, and textile raw material is sandwiched in the horizontal of band along each described terminal line (Klemmlinien) between it.Be different from the peripheral speed that the direction of advance at band increases because cylinder has, the textile raw material that produces from one or more yarn band will be stretched and be simultaneously homogenized therein.
For control with stretching device and adjusting device are set, the band of unit length of yarn band that must determine to leave spinning preparation machine as far as possible accurately is heavy, has possibility because this measured value makes about the TENSILE STRENGTH and the main conclusions of regulating intensity.For example the sensor on the spinning preparation machine entrance and exit is verified to this, and sensor only also only allows about the heavy conclusion of the band of unit length thus indirectly according to corresponding measuring principle work.Therefore the transducing signal that is determined for calibration must be implemented a basic coupling.Therefore must continue monitored of signal and if needed sensor must recalibrate.Therefore heavy the fixing on really in the laboratory of the band of actual unit length realized by the mode that the test product band of obtaining is before weighed usually., also to obtain except determining that the measurement mechanism of accurate yarn strip length obtains accordingly in this necessary measurement accuracy, thereby must obtain a plurality of test product bands and study by the method for Statistics Application by the sky of using pinpoint accuracy is gentle.Must use corresponding laboratory installation for this reason.Be similarly and obtain test product and want the breaks in production process inevitably, in addition, wherein the result of test product analysis is subjected to the time and goes up and the restriction of limited product section (Ausschnitt) quantitatively.
Summary of the invention
Therefore the objective of the invention is to, a kind of technology or spinning preparation machine are provided, weigh with the band of this unit length that realizes reliably determining the yarn band on the spinning preparation machine with short as far as possible time cost and the least possible expense cost.
This purpose realizes by the feature of independent claims.
According to the invention provides, promptly determine the weight of the yarn band that is unfolded and length and determine that thus the band of yarn tape unit length is heavy.In this way unit length be with heavy can directly calculating by these two described values, and need not consider other parameter at this.The length of the yarn band that calculating is unfolded can be determined by the length-measuring appliance that for example has been installed on the spinning preparation machine at this.Both can use direct measuring method also can use indirect measuring method at this.For example for spinning preparation machine, it uses in yarn band exit and extracts cylinder or extract disk, and the length of yarn band can be determined by the increase of extracting cylinder or extraction disk revolution.Same touchless sensor, for example the method that microwave remote sensor or ultrasonic sensor can above-mentioned associations is used.
Particularly preferably be at this, when yarn band that reception is unfolded, use at least one storage device (Ablagevorrichtung).This type of device is used to collect the yarn band that leaves spinning preparation machine.When the yarn band is sent to other spinning machine, for example during rotor spinning machine, storage device is installed usually, and the yarn band must be sent to spinning machine from spinning preparation machine simultaneously.
In this association preferably, container case, the arrow-necked bottle (Spinnkanne) that particularly spins uses as storage device.However, same possible is that the yarn band launches on plate shaped storage device.Yet the container case in the reality proves that such as rectangular or rounded substantially spinning arrow-necked bottle the yarn band is unfolded therein usually point-blank or rotatably.
Particularly preferably be, the weight of yarn band is by the net weight of storage device and comprise that the difference between the gross weight of storage device of the yarn band that is unfolded determines.Do not need other calculating thus and need not introduce other parameter, generate the gross weight of the yarn band that is unfolded in direct mode.
Particularly preferably be the net weight of storage device and/or comprise that the gross weight of the storage device of the yarn band that is unfolded to determine by weighing at this.This on spinning preparation machine, preferably in its yarn is taken the zone of mouth out of, is installed a balance, and its measured value can directly or indirectly be transferred in control corresponding device and/or the memory (Speichereinrichtung).
Equally preferably, when before the yarn band is unfolded, determine the net weight of storage device.Can improve the accuracy of the method in this way effectively, because the weight difference between thus can the single storage device of balance.This difference results from, self the trickle weight difference that for example causes by the manufacturing between the single storage device, but equally also result from line material and/or spot, it is before the storing process of reality Already in the storage device or on the storage device and influence its weight thus.Weight by directly definite storage device before launching at the yarn band is considered this difference, thereby can realize determining yarn band weight with extra high accuracy.
Preferably, the net weight of storage device and/or comprise that the gross weight of the storage device of the yarn band that is unfolded is determined in the zone of spinning preparation machine, the yarn band is unfolded on the spinning preparation machine zone.Therefore, the transmission of storage device (entfallen) (separat) position that falls a separation.Thereby determining of weight can directly realization after launching the yarn band, and measured value can use as far as possible rapidly thus, and for example can be introduced into and be used to control spinning machine.
Equally preferably, the gross weight that comprises the storage device of the yarn band that is unfolded periodically is determined.For example feasiblely in this association be, in storing process the weight of yarn band and obviously the length under it determine to determine in the good spacing in short-term in advance.Same feasible be, the yarn band fully be deployed in the storage device or on the storage device and the weight of the yarn band that is launched fully and length after each expansion process, be determined.Final mode of operation provides the band of the unit length of the yarn band that is unfolded accordingly to weigh for each storage device, can be replaced by new, empty storage device after storage device fills up in the reality.With respect to the method for sample mode, the accessible degree of accuracy with the percentage form has been obtained the raising of essence by a large amount of good materials according to prior art.Apparently, can determine the mean value of the yarn band weight of more storage device thus equally, thereby the heavy mean value of the band of unit length can be subjected to the influence of only fluctuating in short-term equally hardly.
Yet the gross weight that equally preferably, comprises the storage device of the yarn band that is unfolded is determined constantly.Therefore the band of the unit length of determining is heavy may produce bigger fluctuation.But can obtain successive measurements by this way, thereby can discern the heavy variation of band of unit length of the yarn band of production more quickly, and directly apply to control spinning machine.
Particularly preferably be, the band of application units' length is heavy with monitoring and/or spinning preparation machine is set, because these numerical value provide quality about the yarn band of having produced, the direct conclusion of the uniformity of the yarn band particularly produced.When finding the variation of these numerical value timeliness, so this is also indicated, must intervene machine parameter, wherein, the band value heavily that can introduce fixed unit length is as the basis of adjusting relevant parameter.
Preferably, the band of unit length is heavy compares with at least one theoretical value, and uses this difference to monitor and/or to be provided with spinning preparation machine.This theoretical value particularly draws from the unit length band is heavy, and the yarn band of having produced should possess this theoretical value, and may be in considering (value) the corresponding lower limit and the upper limit.
Equally preferably, spinning preparation machine has the stretching device and/or the adjusting device of yarn band.Can make the band of the unit length of the yarn band that passes spinning preparation machine heavily change to value desired when spinning machine is terminal from the initial value when spinning machine enters the mouth by these two kinds of technologies.With respect to elongation default and yarn band that continue usually takes place on stretching device, this elongation adapts to the intensity (Beschaffenheit) at the yarn band at the entrance and exit place of spinning preparation machine constantly on adjusting device.Spinning preparation machine has a lot of sensors usually for this reason, and its measured value is used for adjusting constantly stretching.
Preferably, the difference between the band of unit length weight and its corresponding theory value is in order to monitoring and/or stretching device and/or adjusting device are set in this association.As indicated above, the band of unit length has heavily reflected the basic reference value of drawing process and adjustment process, thereby the deviation between these values and the theoretical value allows the direct conclusion of the correct working method of (zulassen) spinning preparation machine.When monitoring deviation, the rapider intervention of the control device of spinning machine and adjusting device has been guaranteed reliable correction, the rotating speed of the cylinder that for example stretches or the feed speed of yarn band of the corresponding procedure parameter of spinning machine.When unit length surpass a definite value with the difference between the heavy and default theoretical value time, same possible is, the whole shutdown of spinning machine is to avoid waste product or to determining damage of elements.
Equally preferably, this deviation is used for monitoring and/or sensor is set, and it is used for control stretching device and/or adjusting device.Conventional spinning preparation machine has a plurality of corresponding sensors usually, the processing step that its monitoring is single.At this sensor of the tachometric survey of feed roller, tensile roller, bending roller (Umlenkwalzen) and/or calender roller for example, perhaps determine the sensor of yarn band quality (Faserbandmasse), yarn tape thickness and/or yarn strip length.When the heavy deviation theory value of the band of the unit length of the yarn band of producing, it can point out fault on corresponding sensor.This sensor can based on the band of the unit length that is determined heavily be recalibrated or be replaced when damaged subsequently.
According to the present invention, its outstanding part of spinning preparation machine is, first weighing device promptly is installed thereon at least, and weighing is for the weight of the fitting device of the yarn band that leaves spinning preparation machine.Wherein can use a plurality of known weighing devices in principle, for example standard balance or balance are laid thereon hangingly for the fitting device of yarn band.
At this preferably, in the zone of spinning preparation machine outlet, at least one weighing device is installed.Special thus promptly definite yarn band weight is feasible, thereby when with theoretical value deviation being arranged, promptly influences the relevant parameters of spinning preparation machine.Obviously same feasible is to comprise that the fitting device of the yarn band that is unfolded is weighed in the position that is away from this.For example preferably, when a weighing device was installed on a plurality of spinning machines, wherein weighing device was installed in middle position in this case, and storage device is sent to middle position after filling up.
Equally preferably, spinning preparation machine is equipped with the mouth substituting device of replacing the fitting device in the zone of its outlet.It has been realized after the yarn band quantity that storage pre-defines or (bzw.) has reached definite compactedness controlled replacement of draw-out device afterwards.
Preferably, alternative has for the supply area of fitting device and extracts zone (Entnahmebereich).Wherein the supply area provides interim storage especially for the fitting device of sky, thereby has fitting device new, sky to use after the fitting device is filled at any time.Fitting device after this fills is transferred to the spinning machine that extracts the zone and can be transferred to other subsequently by corresponding transmitting device, for example working region of rotor spinning machine by alternative.
Particularly preferably be in this association, first weighing device be installed on the supply area and second weighing device be installed extracting on the zone.Realize the storage of approximately continuous yarn band thus.Promptly when only using a weighing device and can continue to store the yarn band then, the storage device after filling takes that port area is removed out of and the net weight of next storage device when being determined from yarn, can be implemented in the definite net weight supply area in.When filling the back storage device when being transferred to yarn and taken out of port area by mouth substituting device, the net weight of storage device determines, thereby can the directly storage of continuation yarn band replacement process after.Common applied spring in storage device, it presses to memory plane with the yarn raw material that is unfolded, and the neat storage that is unfolded the yarn band with generation is shielded, and its yarn band for the high-quality quality is necessary.The spring of packing into has very big tolerance, and perhaps it can have a negative impact to the result of weighing process.So particularly preferably, before yarn band expanded position and the weighing device of respectively packing into afterwards, because can eliminate the tolerance of elastic force thus fully and reach necessary certainty of measurement.
In particularly preferred design, weighing device is connected with the control device of spinning preparation machine.Realize the quick collection and the processing of the measured value be determined thus.Can be applied to and/or also store the inspection and the setting of the single parameter of spinning preparation machine subsequently.Weighing device can directly for example be connected with spinning machine by cable and/or radio communication in addition.And round-about way is feasible equally, for example has the equipment of the storage device of RFID chip, can store the net weight of corresponding storage device therein.
Equally preferably, spinning preparation machine has at least one stretch zones with the stretch yarn tape.Special the band of the unit length of the yarn band of producing has heavily reflected the judgement parameter in the spinning preparation machine of this type of design, to judge the correct mode of operation of spinning preparation machine.Therefore the monitoring of these parameters is very meaningful in this spinning machine especially, thereby according to the present invention the definite of these parameters has not only been simplified its monitoring that relates to significantly but also simplified adjusting device and control device significantly.
Equally preferably, stretch zones is adjustable.Stretch round a coefficient incessantly at this yarn band.At the lasting monitoring and the setting of drawing coefficient, additionally consider the physical quantity of different yarn bands, the band of special yarn tape unit length is heavy, thereby can produce yarn band especially uniformly.
Preferably, control device is connected with an element of spinning preparation machine at least.For example can be drafting system tensile roller, spinning machine the inlet cylinder to and/or the outlet cylinder to or can be particularly preferred corresponding driving device.Can realize that thus directly affact the assembly of spinning machine on the heavy basis of the band of the unit length that the yarn band that launches is determined, it directly influences these parameters.Thereby opened up a kind of possibility of simplification, so controlled and regulate spinning preparation machine, promptly the band readaptation of the unit length of determining in the exit is in each predetermined theoretical value.
Preferably verified in addition, control device is connected with a sensor of spinning preparation machine at least.Therefore except that the control device and/or adjusting device of above-mentioned spinning preparation machine discrete component, realized the monitoring and the calibration of each sensor of spinning machine equally, wherein the band recast of unit length is that fundamental quantity is introduced into.
Wherein sensor is preferably as determining yarn tape thickness, yarn band quality, yarn strip length, the TENSILE STRENGTH of stretch zones, the adjusting intensity of stretch zones and/or the feed speed (Liefergeschwindigkeit) of spinning preparation machine.Because these parameters reflect the band of the unit length of the yarn band of producing and weigh that this tittle can be introduced into, to check or to calibrate described sensor.
Description of drawings
The present invention sets forth according to the following drawings.Wherein
Fig. 1 illustrates the side view according to the section of prior art;
Fig. 2 section of illustrating is together with the vertical view of the weighing device of installing;
Fig. 3 section of illustrating connects the vertical view of same mouth substituting device and two weighing devices.
The specific embodiment
Fig. 1 illustrates according to the section 1 of prior art as the spinning preparation machine example.
6 independent yarn rope (Faserstraenge) FS are arranged in that the section shown in the summary is placed side by side on 1.Yarn rope FS illustrates visibly from top, and its stage casing 1 is so shown in the side view.
Inlet in section 1 is equipped with funnel 2, and its yarn rope compression (verdichten) becomes single yarn band FB.After passing first measurement mechanism 3, it produces the first measuring-signal S1, for example measuring-signal is explained the quality of the length characteristic of the yarn band FB that sends into, and the yarn band FB that compresses now is sent in the drafting system 4, and drafting system is formed the core component (kernstueck) of section 1.
Drafting system 4 has the inlet cylinder to 5a, and 5b, middle cylinder be to 6a, 6b, outlet cylinder to or be also referred to as feed roller to 7a, 7b, peripheral speed rotation to raise one by one in formation.The different peripheral speed yarn band FB right by cylinder is unfolded in drafting system 4 the nonwoven fabric shape, is stretched corresponding to the ratio of peripheral speed.
The inlet cylinder is to 5a, and the cylinder of 5b and centre is to 6a, and 6b constitutes described predraft zone, and middle cylinder is to 6a, and 6b and feed roller are to 7a, and 7b constitutes described main stretch zones.In the drawing process, not only predraft but also main the stretching are constant at uncontrollable section 1 li.Otherwise in adjustable section 1, stretch highly realization to the adjusting of the quality fluctuation of yarn band FB by change.Main in addition stretching is normally changeable, because the master stretches greater than predraft usually, thereby can realize the adjusting more accurately to the thickness fluctuation of yarn band FB.
Yarn band FB is turned to and provide better yarn to carry thus at the additional pressure bar of installing 8 of main stretch zones.The yarn band FB that stretched then is by turning to cylinder 9 to turn to and be with shaped device 10 to transmit.Band shaped device 10 is configured to funnel type and as the compression of yarn band FB.In the outlet of funnel other measurement mechanism 11 is installed, it has measuring chamber 12, the quality of the yarn band FB that sends in this collection.Quality or thickness are converted to measuring-signal S2 by a unshowned sensing equipment.
The yarn band FB that measures at last by calender roller to 13a, the 13b polishing also transmits to jar bucket storage device (Kannenablage) 14.Jar bucket storage device 14 has the rotary table feeder 15 that rotates round its vertical pivot and together with tape track (Bandkanal) 16 yarn band FB is stored in the spinning arrow-necked bottle 17.Spinning arrow-necked bottle 17 self by unshowned mode perhaps with rectangle spinning arrow-necked bottle point-blank, perhaps move with respect to fixing rotary table feeder 15 with circle spinning arrow-necked bottle rotatably.Therefore spinning arrow-necked bottle 17 whole inner spaces can be by the yarn band FB filling that launches.When spinning after arrow-necked bottle 17 fully fills up, it can manually or by the alternative shown in the summary 18 only be replaced by empty spinning arrow-necked bottle 17 by the operator.
First measurement mechanism 3 comprises a measuring chamber 23 and two disk scanners 24,25, and wherein disk scanner 24 fixed installations and disk scanner 25 are pressed towards disk scanner 24 by pressure and can vertically move to its rotating shaft.At this, the mobile of disk scanner 25 is the yardstick of the quality of yarn band FB.This moves by for example unshowned inductive pick-up collection, and this sensor produces measuring-signal S1.Measuring-signal S1 is by predraft and/or main stretch of control device 19 introducings to change drafting system 4 then.Therefore can regulate the fluctuation of the quality of yarn band FB.This type of method also is known as the open loop control of drafting system 4.
Measurement mechanism 11 in drafting system 4 exits comprises measuring chamber 12, sends into yarn band FB and contactlessly measures yarn band FB by measuring chamber.It is preferred especially to use touchless sensor at this, because the speed of the yarn band FB that advances in drafting system 4 exits significantly is higher than its entrance side naturally.Measuring-signal S2, it is produced by unshowned sensing equipment by measurement mechanism 11, analyzes by Quality Monitoring Control System 22.Gather the mean intensity of yarn band FB especially and remaining inhomogeneities on yarn band FB.When the quality of the yarn band FB that exports can not meet the demands, for example Quality Monitoring Control System 22 can transmit a signal to the control device 19 and the machine that stops.For example can be implemented to operator's information equally by output unit 21-.
Measuring-signal S2 at the measurement mechanism 11 in drafting system 4 exits equally often directly is transferred to control device 19.Thereby for example because defective quality can independently realize closing of spinning preparation machine by control device 19.Same feasible is promptly to introduce the stretching of measuring-signal S2 with control drafting system 4.So the closed-loop control that realizes is particularly suitable for long-term bias adjustment to the theoretical value direction.
In a word, when measurement mechanism 3 and measurement mechanism 11 at this measuring-signal S1, S2 that is introduced into enough accurately the time, the best of the yarn band fluctuation of advancing is regulated just possible.The measuring-signal S2 that same effectively quality collection only has corresponding accurate measurement mechanism 11 is just possible.
Measurement mechanism at this spinning preparation machine is harmonized and calibration with expensive manual methods.Therefore manually showing the reference gauge with known thickness and the measuring-signal of corresponding measurement mechanism in the measurement mechanism of mechanical type sampling compares with the theoretical value on the corresponding theory curve.These realize that by the reference gauge of a plurality of different-thickness thickness covers whole measurement categorys of each measurement mechanism usually.Each measurement mechanism is aligned and recalibrates after manually implementing this type of detection order.The measurement result of measurement mechanism is checked in laboratory extraly in the heed contacted measure system.Be changed in the step that repeats if any the deviation sensor characteristic, obtain corresponding consistent up to the measurement result of sensor and the measurement result of laboratory.
Because high relatively expense, this type of calibration steps are merely able to carry out in the long relatively time interval.And the distortion (Verfaelschung) that fast-changing in short-term influence factor can not gather and limit thus on corresponding measuring-signal can not be revised.The wherein particularly distortion of measuring-signal in addition, its variations in temperature by measurement mechanism is caused.The distortion of same measurement result is produced by the filth of adhering in measurement mechanism.Distortion by temperature effect or the filthy measurement result that produces more or less occurs in all known measuring methods significantly.
The synoptic diagram of Fig. 2 section of illustrating 1 is taken mouthful 26 places out of at its yarn weighing device 27 is installed.It is used for determining the weight of yarn band FB, aforesaid yarn band, in the section of leaving 1 afterwards by rotary table feeder 15 in storage device, the form of the arrow-necked bottle 17 that for example spins is unfolded (see figure 1).
30 be transferred to weighing device 27 at the spinning arrow-necked bottle 17 of this sky from the supply area, weighing device is used for determining the net weight of spinning arrow-necked bottle 17.When spinning arrow-necked bottle 17 was filled into predetermined compactedness by yarn band FB, storage device was weighed again.Subsequently from the net weight of spinning arrow-necked bottle 17 and the arrow-necked bottle 17 that spins together with the weight that draws the yarn band FB that is unfolded the difference between the gross weight of the yarn band FB that is unfolded therein.
The band that obtains unit length subsequently from be deployed in spinning arrow-necked bottle 17 in the length that is determined of yarn band FB and the weight under it is heavy.For example the direct control device 19 by section 1 of this value calculates and is used for, and as described below, checks and/or be provided with spinning preparation machine, particularly at the drafting system shown in Fig. 14.To this, for example weighing device 27 is connected with control device 19 by corresponding cabling 28.
With respect to the length of yarn band FB and the weight of yarn band FB, its each after spinning arrow-necked bottle 17 is by complete filling, can be determined, obviously same feasible is that these two values are determined in expansion process continuously or only at a fixed time.
Fig. 3 is the vertical view of the section of illustrating 1 equally, and it has a mouth substituting device 18 shown in the summary, and for example it can have turnstile 29, and spinning arrow-necked bottle 17 can pass through its motion.Alternative 18 has supply area 30 in addition, to store empty spinning arrow-necked bottle 17 and to extract zone 31 for the spinning arrow-necked bottle 17 of being filled by yarn band FB.
Not only weighing device 27 respectively is installed at this in supply area 30 but also on extraction zone 31.It preferably promptly arrives before section 1 yarns take mouthful 26 zones out of at spinning arrow-necked bottle 17, and the net weight of spinning arrow-necked bottle 17 can be determined.In case empty spinning arrow-necked bottle 17 is moved to this zone for filling by alternative 18, net weight storing process known and yarn band FB can directly continue to carry out behind the replacement process of spinning arrow-necked bottle 17.The spinning arrow-necked bottle 17 of being filled by yarn band FB is weighed again by second weighing device 27 in the extraction zone 31 of alternative 18 subsequently, thereby from the net weight of spinning arrow-necked bottle 17 with comprise the actual weight that can determine the yarn band FB that is unfolded the difference between the weight of spinning arrow-necked bottle of the yarn band FB that is unfolded.
Preferably be connected at this this two weighing devices 27, thereby can directly analyze the value that is determined with the control device 19 of section 1.After calibrating, value and known theoretical value then can intervene the important machine parameter of section 1 and the important machine parameter of corresponding drafting system 4 by control device 19.
For example can regulate in this way the inlet cylinder to the rotating speed of 5a, 5b, middle cylinder to the rotating speed of 6a, 6b, feed roller to the rotating speed of 7a, 7b and/or calender roller rotating speed to 13a, 13b, thereby can so regulate the stretching and the adjusting device of drafting system 4, the heavy final its corresponding theory value that is fit to of the band of the unit length that promptly is determined.The heavy conclusion of the band of same unit length is transferred to high-effect (Funktionstuechtigkeit) of the sensor shown in Fig. 1, and for example the disk scanner 24,25 of section 1 porch also or the measurement mechanism 11 in its exit.Calibration based on the band sensor heavily of unit length is feasible equally in addition, thereby these values can be as the general basic reference value for whole parameters of determining by each sensor.
The band of the yarn band FB unit length of being determined by foundation the present invention re-generates basic reference value in a word, and introducing basic reference value not only can be for regulating and control and can and calibrate each driven element on the sensor shown in Fig. 1, measurement mechanism 3,11 and/or spinning preparation machine for monitoring.
Foregoing invention specifies according to embodiment.Variation of the present invention undoubtedly is in the claim scope, and wherein the feature of all mentioning in specification and the diagram can both realize clearly with mutual combination arbitrarily, is significant and feasible on the whole.Thereby this defines the not only section of comprising by spinning preparation machine, and comprises whole spinning preparation machines, and the band of yarn tape unit length reflects that heavily important parameters is to be used for control and/or monitoring spinning preparation machine thereon.
