Description
Invention field
Preamble according to independent claims, the present invention relates to the spinning field, relate in particular to the field of in spinning or the winder process yarn being monitored, the invention still further relates to a kind of weaving loom (as spinning machine or bobbin-winding machine etc.), a kind of yarn monitoring equipment and a kind of yarn monitoring system that is used for above-mentioned weaving loom, and relate to a kind of method that the yarn at spinning machine workstation place is monitored.
Background technology
The equipment and the method that are used for monitoring the weaving loom yarn are known.The purpose of yarn monitoring is in order to ensure the yarn qualities that obtains expecting.For example, the time response of the yarn parameters such as quality in reply per unit length and/or the diameter is collected.This collection generally uses electric capacity, optics and/or other sensor to finish.
By suitable estimation make can from the time response of the yarn parameter collected, know by inference and given value between bad deviation.Such defective may take place randomly or periodically.According to the assessment result of these defectives, trigger different actions automatically.When class-one defect takes place very when, can interrupt spinning and the winder operation to eliminate the defective in the yarn, also can send alerting signal.Test result can be collected in the statistical system, and this statistical system can provide the information about yarn qualities.
For many years conventional way is: each workstation (as spinning workstation or winder workstation etc.) at weaving loom locates to be provided with respectively a yarn monitoring equipment, passes in the process of workstation at suspicious yarn, and described equipment can be monitored this suspicious yarn continuously.For example, in GB-638365, describe an example of this yarn monitoring equipment, be also referred to as the clearing machine.Yarn monitoring equipment generally includes a simple local assessment unit, is used for the estimated sensor signal.This estimated result is used for determining whether cutting off yarn; Under aforementioned circumstances, estimation unit can send shutoff signal to the cut-out equipment that is fixed on the workstation.
Usually, a plurality of yarn monitoring equipment link to each other with a clearing machine check unit, and described clearing machine check unit is used for monitoring on the one hand and controls above-mentioned yarn monitoring equipment, are used for registration on the other hand and estimate that yarn cuts off and yarn cuts off incidents such as triggering.This clearing machine check unit can carry out communication with the weaving loom control unit in the weaving loom.Being connected by data line between yarn monitoring equipment and clearing machine check unit realize, and described data line is preferably data bus, and described like this clearing machine check unit and a plurality of yarn monitoring equipment can be connected in this data bus simultaneously.DE-3928831 A1 and DE-19548667 A1 have mentioned about the possible structure of data bus and the example of necessary basis facility thereof; But the data bus that will mention of there is used to realize the communication between workstation and weaving loom control unit, so it doesn't matter with yarn monitoring.And for the yarn of rapid movement and a plurality of yarn monitoring equipment that link to each other with clearing machine check unit, owing to can accumulate mass data at short notice, therefore the management meeting to these data proposes higher requirement to the electronics package in each yarn monitoring equipment, data bus, clearing machine check unit and relevant interface.
Except the parameter of being correlated with yarn, the method for collecting other parameter that has nothing to do with yarn by metological method also is known.Thereby, the method that the removable cone frequency converter that utilizes in the bobbin-winding machine comes the mass parameter of collection cone is disclosed in EP-0650915 A1.For example, described mass parameter can be cone diameter, winder density, pyramidal tract to or axial distortion etc.Collection to above-mentioned parameter is comparatively simple, monitors described cone and can realize by fix an image pick-up device on described cone frequency converter.Like this, except data, also need accumulate many other data, and these data must be transmitted and be handled too about yarn monitoring equipment.Therefore, the additional function of cone monitoring makes bobbin-winding machine become more expensive and complicated.
Several years ago, can't accomplish almost that technically the data relevant with single yarn that yarn monitoring equipment is collected transmit continuously.For this reason, according to US3885232, yarn monitoring equipment need be equipped with memory device, and these memory devices are visited in clearing machine check unit (one by one promptly) periodically according to the order of sequence.US-4137699 A1 discloses similar scheme, however its be not by electrical lead with data transmission in the fixed clearing machine check unit.But clearing machine unit is arranged on one movably on the joint vehicle frame, and this joint vehicle frame can be near each spinning unit.Therefore, can with the not contacted situation in clearing machine check unit under transmit collecting from the data that are provided with the spinning unit of joint vehicle frame.Above-mentioned serial data transmission system has following remarkable shortcoming: promptly when critical defect takes place, can't in time intervene.
Recently, technical development realized and can will be transferred to clearing machine check unit from the data sync of a plurality of workstations (promptly continuously and simultaneously), and in described clearing machine check unit it estimated and handle.For example, in US-4984749 A, this is described.Yet, still need complex mechanical construction owing to will carry out synchronous data transmission, finally make price comparatively expensive.Electronics package in each yarn monitoring equipment is comparatively complicated, and must lay many expensive parallel bus and be used as data line, thereby make and on all yarn monitoring equipment and clearing machine check unit, suitable and expensive interface must be installed successively.
The purpose of DE-19907684 A1 is control and the information system of improving in the weaving loom, especially will reduce its manufacturing cost.This can realize that this treater also can be used for estimated sensing signal and the cleaning of control yarn by the treater in the given workstation except the described workstation of may command.Communication between workstation and weaving loom control unit then is to use shared data bus to finish.
DE-19505023 A1 has proposed by the weaving loom control unit being placed in the method for thoroughly saving data bus on the joint vehicle frame.Data link on the control convenience of this weaving loom control unit and each workstation, all is equipped with, between described weaving loom control unit and each control convenience, to carry out bidirectional data exchange.In case the joint vehicle frame navigates to each control station front, and data exchange will take place.Data exchange unit on the one hand can be with the quantitative data input workstation control convenience relevant with workstation, yarn bag or yarn qualities, on the other hand, also can be with the yarn qualities quantitative data input weaving loom control unit that measures by this data link, to make report about yarn qualities.
Sensor and estimating apparatus on the joint vehicle frame, be equipped with according to DE-10159153 A1,, to be used to monitor yarn qualities.Use this sensor and estimating apparatus, can collect the yarn qualities scale value, and can this yarn qualities scale value be transferred to suitable workstation via the weaving loom control unit of weaving loom by appropriate data bus.Use this scale value that the clearing machine is calibrated.When all clearing machines have all been carried out calibration with said method after, just can guarantee that to the measurement that yarn qualities carries out be equal, and for all workstations, above-mentioned measurement all is repeatably on time and space.

Fig. 1 and Fig. 2 are the schematic block diagram of two embodiment of spinning machine of the present invention;
The diagram of circuit of an embodiment of Fig. 3 the method for the invention.
The specific embodiment
Fig. 1 is the block diagram of a plurality of assemblies in the described spinning machine 1 of basic invention.Elongated machine frame 11 is supported with a plurality of spinning units 3.1,3.2 ..., 3.n.New-type spinning machine comprises into hundred this spinning units, and these spinning units are that unit is merged into parts 12.1,12.2 with every n spinning unit ..., 12.m.M and n are natural number, generally get m ≈ 16, n ≈ 20.Unless otherwise noted, following will only the explanation in detail to parts 12.1.Certainly, the extraordinary circumstances when these spinning units also can be applicable to m=1 promptly do not have the spinning machine of parts; And can do necessary the modification to other parts under the more general situation.For simplicity, this figure also only schematically shows in this scope, and the spinning unit 3.1,3.2 that also only draws in the figure ... m, 3.n are arranged in an end of machine frame 11 one by one; Yet under normal conditions, spinning unit is answered the two ends of preferred arrangement at machine frame 11.
Preferably, each spinning unit 3.1-3.n comprises gauge head 30.1-30.n, and described gauge head is used to collect the temporal characteristics of each at least one characteristic of yarn (not shown).For realizing this purpose, each gauge head includes the sensor of capacitive, optical profile type and/or other types at least.Provided an example of this gauge head among the EP-924513 A1 with capacitance-type sensor.Through suitable estimation, from the temporal characteristics of at least one yarn property of having collected, can know by inference and given value between bad deviation.Should take adequate measures according to the type of deviation, these measures can comprise interrupt the spinning operation, eliminate defective in the yarn, on bobbin-winding machine, cut off yarn, send alerting signal, action such as collect statistics.
And spinning machine 1 comprises parts inspection unit 13.1-13.m at least, and preferably, described parts inspection unit 13.1-13.m corresponds respectively to each parts 12.1-12.m.Each parts inspection unit 13.1-13.m is used for cross-check sum and controls a plurality of spinning unit 3.1-3.n.For realizing this purpose, in parts 12.1, parts inspection unit 13.1 links to each other with each spinning unit 3.1-3.n by appropriate data link (as element bus etc.); Yet succinct for the accompanying drawing picture, these data links do not draw in Fig. 1.And on the other hand, for the present invention, parallel data transmitting device 5.1-5.n outbalance is used to be implemented in 13.1 functions of carrying out data transmission of each gauge head 30.1-30.n and parts inspection unit.
Target of the present invention is to reduce the purchase cost of spinning machine 1, and simplifies spinning machine 1 and yarn monitoring system thereof.For above-mentioned reason, the present invention starts with from following these a large amount of assemblies that exist: i.e. spinning unit 3.1-3.n and parallel data transmitting device 5.1-5.n.By being reduced to MIN method, its function simplifies said modules.In particular, this is meant that the data that will be obtained by the gauge head 30.1-30.n among the spinning unit 3.1-3.n are divided into following two kinds of data types at least:
(i) time critical data can force the spinning operation is intervened fast.For example, this time critical data can be used for the spinning operation in suspicious spinning unit place operation triggered and closes or action such as interruption.These data comprise with yarn per unit length or thickness in the relevant details of quality, especially yarn node, thick partially point or partially Bao Dian etc. locate in per unit length or the thickness quality respectively and the deviation between certain given value.The time critical data is that (promptly continuous) is transferred to the parts inspection unit 13.1 from each spinning unit 3.1-3.n synchronously, and can intervene the spinning operation immediately in case of necessity.Thereby having guaranteed can residually not have bad defective in yarn.
(ii) non-critical data of time can not force the spinning operation is intervened fast.Non-critical data of this time can comprise a large amount of take off data of gauge head 30.3 records or only comprise wherein partial data.Preferably, these data packets contain the details such as quality in yarn per unit length or the thickness, refer in particular to per unit length or thickness endoplasm quantitative statistics distribution situation, thereby the yarn qualities information about suspicious spinning unit 3.3 is provided, and/or the systematic error information in the spinning operation.Non-critical data of this time only can be serially, and (promptly intermittent and asynchronous) is transferred to the parts detector 13.1 from all spinning unit 3.1-3.n.By this method, data to be transmitted amount and desired data transmission rate have been reduced.
Parallel data transmitting device 5.1-5.n is used for the transmission time critical data.Why say that to state device be " walking abreast ", be because they help in continuous with synchronous mode in 13.1 transmission of each gauge head 30.1-30.n and parts inspection unit data relevant with suspicious yarn, and be not all gauge heads that must refer in the spinning machine about the statement of " each gauge head " wherein, also all gauge head 30.1-30.n in the finger part 12.1 or refer to have the gauge head of other labels only.Described parallel data transmitting device 5.1-5.n can be designed comparatively simply and cheap, preferably it can be designed to simple electrical lead.Therefore, the interface between described parallel data transmitting device 5.1-5.n and spinning unit 3.1-3.n and processor unit 2 is also comparatively simple and cheap respectively.Preferably, described concurrency data link 5.1-5.n is set to the one-way data transmission to parts inspection unit 13.1 by each gauge head 5.1-5.n.The time critical data can transmit for the form of the binary signal of " 0 " or " 1 " by value.As an example, described time critical data can provide following three types signal:
(a) short signal that representative " is lacked thick point and closed the spinning operation ";
(b) the long signal that representative " is grown thick point and closed the spinning operation ";
The continuous signal of (c) representative " emission is reported to the police ".
The second, serial data transmission device 6 has the function of non-critical data of transmission time.Why saying that to state device be " serial ", is because their only can be in 4 transmission of a selected spinning unit 3.3 and removable module data relevant with suspicious yarn.In case after this data transfer is finished, will select another spinning unit, and removable module 4 can move to this another spinning unit place, data will be in this another spinning unit and 4 transmission of removable module then.Suspicious spinning unit 3.3 can be selected from all spinning unit 3.1-3.n of spinning machine 1, also can only select from one group of spinning unit (for example spinning unit 3.1-3.n of parts 12.1).The selection of suspicious spinning unit 3.3 can be a ccasual, can be target by specific criteria also.This serial data transmission device 6 can use light wave, infrared waves, radiowave, electromagnetic induction or electrical lead to wait and realize data transmission.
If removable module 4 is installed on the joint vehicle frame of spinning machine 1, be selected to the spinning unit 3.3 that carries out serial data transmission so and should be preferably at that time joint vehicle frame 40 and must carry out that spinning unit of joint operation, or be adjacent spinning unit 3.2 or 3.4 it.Data link
Preferably, should be the estimation unit 43 that described removable module 4 outfits one are used for non-critical data estimated time.In the embodiment shown in fig. 1, this estimation unit 43 is fixed with respect to machine frame 11.At first, provide an additional data transmission device 61, be used for this second kind of data set is transferred to estimation unit 43 from removable module 4.Estimation unit 43 can link together with machine control unit 2 by the second additional data transmission device 62, but also can not link together with described machine control unit 2.Described additional data transmission device 61,62 is preferably used data line, but also can be contactless.Machine control unit 2 links together by the parts inspection unit 13.1-13.n in suitable machine data link 21 and the spinning machine 1, and wherein machine data transmitting device 21 can be the machine bus, also can be simple data line.
At first, serial data transmission device 6 can be used for via removable module 4 to non-critical take off data of 43 transmission times of estimation unit, non-critical take off data of these times is relevant with the yarn of weaving in selected spinning unit 3.3, and is recorded by the gauge head 30.3 on this selected spinning unit 3.3.Preferably, each gauge head 30.1-30.n all disposes (and non-registered have) has memory storage, non-critical data of the time of collecting can be kept at earlier in these memory storages, elected in behind the spinning unit 3.3, by serial data transmission device 6 these data are read again.
Secondly, serial data transmission device 6 also can be used for to selected spinning unit 3.3 transmission data.Can the structured data etc. of gauge head 30.3 to the data of selected spinning unit 3.3 transmission.These data can be divided into static structure data and dynamic structure data.The static structure data are thick-and-thin absolute reference dividing values, and for meeting specific quality loop, these parameter dividing values can not be exceeded, and for instance, the length that is departed from can not depart from mutually with the given value of yarn thickness exactly.The dynamic structure data are relative datas, can change along with the time, for example, are the aviation value of yarn parameter (as yarn thickness etc.) in all spinning unit 3.1-3.n or the one group of spinning unit.Sometimes, the dynamic structure data are very useful in the operation in spinning, for example can be used for determining that threshed material changes after, whether wrong yarn counting has taken place.
For the data transmission of being undertaken,, removable unit 4 is good if can intermittently staying at selected spinning unit 3.3 places by serial data transmission device 6.If removable module 4 is installed on the joint vehicle frame 40, generally all can adopt aforesaid way.But might not realize like this, especially for removable module 4 in when motion, can produce the situation of non-contact data transmission.Therefore, as for the mobile fan on the bobbin-winding machine, just can use this not with the data transfer mode of pause.
And, preferably, in each parts 12.1-12.m, include feeding mechanism 14.1-14.m respectively, be used for supplying energy to gauge head 30.1-30.n.For instance, this supply can be via energy bus 15.1 or is provided via independent supply line alternatively.
Fig. 2 schematically illustrates an embodiment of spinning machine 1 of the present invention, and wherein removable module 4 itself is equipped with removable gauge head 41 at least.This removable gauge head 41 is used to collect at least one characteristic of suspicious yarn, as the quality in per unit length or the thickness.Removable gauge head 41 can add on described removable module 4 or the removable service aid 40 by gauge head arm 42.Preferably, described gauge head arm 42 moves as follows: can make coupled removable gauge head 41 move to suspicious yarn place on the one hand and implement to measure; Also can not hinder removable module 4 and removable service aid 40 to move to other spinning units on the other hand from a spinning unit 3.3.That gauge head arm 42 can be designed to pivoting or type of extension.When being joint vehicle frame 40, preferably, removable gauge head 41 should add on the described joint vehicle frame 40 as follows: promptly should make removable gauge head 41 implement at selected spinning unit 3.3 places to measure, and this spinning unit 3.3 is adjacent to the current spinning unit 3.2 of carrying out the spinning operation.On removable module 4, also can fix a plurality of gauge head arms, and each gauge head arm has one or more removable gauge heads respectively.Use serial data transmission device 6 to carry out data transmission at removable gauge head 41 and 4 of removable modules; For example, in order to realize this purpose, serial data transmission device 6 can use infrared waves or radiowave.
Further difference between embodiment illustrated in figures 1 and 2 is: in Fig. 2, estimation unit 43 is integrated in removable service aid 40 inside or links together with this removable service aid 40 at least, so that this estimation unit 43 can move with removable module 4.In the embodiment shown in Figure 2, there is not annexation at estimation unit 43 and 2 of machine control unit.Therefore, removable module 4 can be described as independently.Estimation unit 43 is independently selected suitable spinning unit 3.3, and the data of obtaining at these spinning unit 3.3 places are estimated.
Fig. 3 has schematically shown an embodiment of the method for the invention in a flowchart.By gauge head 30.3 temporal characteristics of at least one yarn property is measured 101 continuously.In suspicious gauge head 30.3, take off data is estimated 102 continuously.Based on above-mentioned estimated result, judge that in gauge head 30.3 103 these take off data are that the time critical data still is non-critical data of time.With respect to traditional clearing machine, this criterion comes down to known, and also has a detailed description in as US-3577854 A, CH-678173 A5 or EP-0877108 A1.For instance, this standard can be: whether exceed the clearing dividing value or be reduced to below the clearing dividing value.Wait action 105 for spinning unit 3.3 being triggered close, use parallel data transmitting device 5.3 that parts inspection unit 13.1 is arrived in 104 instantaneous transmission 106 of time critical data.Then, more described time critical data is preserved in 108 the memory storages in the gauge head 30.3.And on the other hand,, only can preserve 108 to it for non-critical data 107 of time, and trigger action immediately not.Constantly carry out above-mentioned steps, up to satisfying in the condition that gauge head 30.3 and 4 of removable modules carry out data transmission.Whether just in its vicinity gauge head 30.3 constantly checks removable module 4.If removable module 4 in its vicinity, just the data transmission 110 that will preserve by serial data transmission device 6 is in removable module 4.The data of having preserved then, just can be transferred to the estimation unit 43 to treat further use from removable module 4.
