Abstract
Electronic control device to discriminate the false contacts and to signal the temporary contacts in a warp stop motion device of a loom. Said control device allows to discriminate the temporary closing of the electric circuits of the banks determined by electrostatic phenomena, from those determined by temporary contacts of the drop wires, detecting the presence or absence, for a predetermined number of successive cycles, of the electric signals existing on the circuits of the banks, by means of a high-frequency synchronous time sampling.
Description
The present invention relates to be used for distinguishing and touch and a kind of electronic-controlled installation that temporarily contacts with signal indication in the Warp stop motions misconnection of loom.Especially; the present invention relates to be used for a kind of electronic-controlled installation of the operation of Warp stop motions; it allows to distinguish (the touching hereinafter referred to as misconnection) that determined by electrostatic phenomenon and the temporary transient temporary transient closure that contacts the circuit of (hereinafter referred to as the temporary transient contact) bank that is determined by menopause tablet; and therefore allow; in first kind of situation, prevent any loom shutdown of not expecting; with in second kind of situation, the operator finds these related warp thread districts of temporary transient contact rapidly.
Experienced in the prior art personnel know that Warp stop motions is a kind of lasting integrality and successional device that is used at every warp of loom control.Said apparatus generally includes one or many contact rods, is called " bank ", crosses that warp thread is placed or on warp thread.Each bank is made up of the U-shaped housing of an outside and the core of an inside, all is metal, is separated by one deck thin insualting material.Each bank has a plurality of menopause tablets, i.e. foil, each menopause tablet comprise a groove-permission it is inserted on the bank-and the hole below that a warp thread is inserted in wherein.
In the loom operation, the housing of each bank and core are connected on the terminal on an electrical resistivity survey survey time road, and menopause tablet is lifted at the top of bank by pulling up of the yarn in the hole of passing it.When a warp thread disconnected or relaxes, corresponding menopause tablet was no longer mentioned by this yarn, dropped on bank, produced a metal bridge between the outer shell-and-core of this bank, and the therefore closed circuit that is connected to the there.The closure of the circuit of one of bank causes starting an automated procedure and stops loom and send fault-signal to the operator.Even this warning generally include a signal roughly or common-normally be positioned on the loom turntable signal lamp or acoustic signal-it make the operator outside certain distance, also can determine the signal that loom has been shut down and accurate or special--normally being positioned at a signal lamp of an end of each bank--it make the operator infer the warp thread broken string of which bank at once.
Recently, people have proposed to make the bank that has a special construction, because this structure, accurately signal can not only be indicated the bank that relates to the warp thread broken string, and can indicate broken string to occur in the concrete zone of this bank, make the operator can find broken yarn quickly like this.These improved recoil simulators also comprise signal lamp or the display that is easy to indicate warp thread broken string position, because they are along the special position of bank, or owing to represent broken yarn point and a reference " zero " point, the initiating terminal of common corresponding bank, between a digital demonstration of distance.
Yet in the real achievement of braiding operation, some exceptions of those states that in the circuit of bank, only are in stable disconnection (promptly not having yarn to fall) or closed (at least one one thread falls) of described up to now theoretical case-be-meet.In other words, frequent state is that the closure of bank circuit occurred in a bit of time, so the off-state of circuit is recovered immediately.As the concise and to the point narration of above institute, this of short duration closure state of bank circuit can more corresponding different states of weaving cotton cloth.
At first, have some special electric reasons: in fact, the motion that warp thread passes thousands of menopause tablet produces an accumulation of static electricity, and it may be discharged to the bank circuit interimly, has determined the of short duration closure of circuit.This state is commonly called " misconnection is touched " in this section.
May also have some mechanical reasons in addition: in fact, braiding in service may produce special malfunction-quilt in the prior art the veteran be called " temporarily contact "-wherein warp thread pine, reach the degree that corresponding menopause tablet is contacted with bank, thereby its signal circuit of closure, but very fast this root warp thread partly recovers its tension force, therefore mention menopause tablet again on bank, and recovered the off-state of this bank circuit.Yet, the malfunction that this is special or determined by warp thread of short duration lax-wherein, also may in fabric, not produce flaw-or conversely, can be by real the determining of warp thread with fracture completely, but it stumbles adjacent yarn, and therefore corresponding menopause tablet is lifted on the bank.This a kind of state in back is quite serious certainly, because it will be formed with the fabric of major defect; In any case therefore the operator need carry out control accurately on warp thread, even also should be like this when " temporary transient contact ".
On the other hand; owing to can not distinguish " misconnection is touched " and " temporarily contacting " to the Warp stop motions that adopts prior art; thereby each Warp stop motions detects one of these contacts; in any case loom needs hard stop; and the roughly signal demand that previously described indication loom is shut down is light yellow still, to remind the supply existing problems of operator's warp thread.Otherwise for stopping that misconnection is touched or temporarily contacted, previously described accurate signal disappears immediately, only because the electric contact that this accurate signal is directly produced on corresponding bank from menopause tablet.Therefore, as long as contact is not lasting, the operator is forced to or checks the whole warp thread-in order to find the yarn that is temporarily contacted potential impact organized, and, repair if desired it-or conclude that all warp thread are in normal position, and to draw this be that a misconnection is touched.Find out obviously that from above this operation not only spends the considerable time, and need the workman who is skilled in technique, promptly determine and in the acceptable time restriction, can detect the existence or the disappearance of fault in the warp thread, the auxiliary signal of any kind was lost efficacy.
Target of the present invention provides a kind of control device, and it allows, and at first, differentiates misconnection and touches and temporarily contact, and prevents the loom shutdown when giving birth to when misconnection triggers.Another target of the present invention provides a kind of signaling arrangement, it allows the operator, be similar to and dropping at last by an one thread, under the guiding of the signal that said apparatus was sent when the yarn that drops thus contacted lastingly with bank, can find the position of decision yarn of temporary transient contact on Warp stop motions rapidly.
According to the present invention, above-mentioned target is comprised by control electronics realization-this type of the Warp stop motions of loom: a plurality of banks side by side, inserting a plurality of menopause tablets above each, menopause tablet by the tension force of the corresponding warp thread of the hole of passing it or groove be lifted at bank above; The device that the control loom is shut down; It comprises an electronic loop that is easy to probe current signal in the circuit of each bank of Warp stop motions to indicate the bank of the one thread that drops on it or the signaling arrangement in its district-it is characterized in that, with one be easy to control above-mentioned electronic loop and thereby handle the Signal Processing unit that sends, its is differentiated because the misconnection that static discharge on the bank or other electric transient phenomenon cause is touched and dropping owing to menopause tablet on the bank, even temporarily, and the true contact that causes, and just in case true contact takes place, stop the operation of loom and send relating to above-mentioned bank, or the caution signal first time of bank part.
According to a feature of the present invention, above-mentioned processing unit after inferring a true contact, is further handled coherent signal, checks that whether this true contact is or becomes a temporary transient contact, and second kind of situation, sends caution signal for the second time.
In one the of the present invention embodiment that selects the superior, the above-mentioned current signal in the circuit of each bank of Warp stop motions is converted to data signal at this signal of transmission to above-mentioned processing unit.
A feature according to this embodiment that selects the superior of the present invention, in order to distinguish that the misconnection that causes owing to static discharge on the bank or other electric transient phenomenon is touched and because the dropping of menopause tablet on the bank, even temporarily, and the true contact that causes, processing unit is carried out following operation to above-mentioned signal:
--with a time sampling, detect the existence of each bank or the current signal in the bank circuit partly of Warp stop motions, or do not exist;
--to each sampling circulation and each bank or bank part, in an adder, for any sampling circulation that detects the signal existence increases a value that presets;
--for detecting the non-existent any sampling circulation of signal, from above-described adder, deduct the identical value that presets, perhaps cancel the value that all have added;
--the total value of more above-mentioned adder and predetermined threshold value (n, p); And
--to the total value and the signal that above-mentioned threshold value equates of above-mentioned adder, be inferred as a signal of the true contact of menopause tablet on the indication bank.
According to another feature of the present invention, in order to check the true contact of having been inferred whether to be or to become a temporary transient contact, processing unit is carried out following operation to above-mentioned signal:
--with a time sampling, at the bank that true contact is taking place, or on the circuit of bank part, continue the existence of sensed current signal or do not exist;
--to each sampling circulation and each bank or bank part, in an adder, increase a value that presets for detecting the non-existent any sampling circulation of signal;
--for detecting any sampling circulation that signal exists, from above-described adder, deduct the identical value that presets, perhaps cancel the value that all have added;
--the total value of more above-mentioned adder and predetermined threshold value (m, q); And
--the total value and the signal that above-mentioned initial value equates of above-mentioned adder are inferred as a signal of indicating the temporary transient contact of menopause tablet on the bank.
According to another feature of the present invention, above-mentioned second interrupted signal lamp is relevant with above-mentioned first continuous signal lamp, or replaces it.
The present invention is with reference now to accompanying drawing, and details are as follows:
Fig. 1 is the block diagram of expression according to the general method of operation of the control electronics of loom Warp stop motions of the present invention; With
Fig. 2 is the flow chart of the order of the inner performed logic operation of this electronic-controlled installation processing unit of expression.
According to the present invention, the control electronics of loom Warp stop motions is characterized as-compares with the control electronics of known type-integrated by the microprocessor in the signal detection electronic loop known per se.By suitable algorithm, may be according to the sequential processes signal of logic operation in above-mentioned microprocessor, it allows to differentiate misconnection and touches and truly contact, and, in true contact, send signal in a different manner with respect to lasting contact for temporary transient contact.
Therefore the block diagram of Fig. 1 does not represent to be used to detect and handle the loop standard drawing of the signal of telecommunication on the circuit that appears at completely normal Warp stop motions G bank.Above-mentioned normal signal detects and handle electronic loop to be represented by module E, and comprises a voltage generating unit and a Digital to Analog Converter.The operation of module E is controlled by processing unit C, and this processing unit C comprises a microprocessor of for example being made by Motorola and selling with code 68HC705J1A.Processing unit C also controls first caution signal A and second caution signal B, and equipment S stops the main motor of loom.
Reference flowchart Fig. 2 is described in the performed logic operation order of processing unit C among first embodiment of the present invention now.In order to simplify narration, hereinafter with reference to the circuit of the independent bank of Warp stop motions; But significantly, be present in bank or controlled bank part in this device for all, by opening their corresponding signal lamps, operation is hereinafter described repeated in identical mode by unit C.Therefore unit C send first ask request module E carry out bank (module 1) go up shown in a time sampling of signal, response receives indication signal on this bank and exists or non-existent data signal.Best, sample of signal length is than short many of sampling period, and like this, many misconnections with short length are touched and are not detected or are detected with the number of the reduction of sampling period.For example, sample of signal length is the microsecond level, and the sampling period is 1/10th Milliseconds, and its wheel synchronization type preferably.
Formerly checked after a caution sign (module 5) has activated, and shown to exist or do not exist the data signal of a signal of telecommunication to be checked (module 2) by unit C then on the bank circuit.The operation of narrating unit C under the condition that caution sign is not activated now, and the operation of unit C under opposite condition will be narrated subsequently.
After checking caution sign not to be activated, above-mentioned data signal is examined, and infers whether its shows on bank circuit to have (value 1) or do not have (value 0) signal of telecommunication.If this signal equals 1, this value is added into a special counter (module 3); Do to equal 0 if it changes, it is 0 that the accumulator of counter is reset.
Therefore this signal controlling process continues circulation, is detected one up to unit C and presets, and wherein exists to circulate continuously n time of this signal, and promptly the accumulator of counter reaches this value n really.The value n according to service condition, fabric type, the increase of static discharge or minimizing, or the like be provided with experimentally.
In the work-based logic according to the device of first embodiment of the invention, the control that signal exists in the continuous synchronization circulation of abundant quantity is actually in order to differentiate misconnection to be touched and truly contacts.From the angle of statistics, the static discharge on the possibility bank, or other electric transient phenomenon in fact hardly can produce n the sampling circulation that continuous length is very short constantly regularly.Therefore clearly, have n circulation continuously if counter total has reached signal, so necessarily have a true contact, promptly an one thread drops on bank, even may be temporary transient.
In fact it should be noted that the selected enough height of numerical value n energy touch in order to differentiate misconnection in true contact, and enough low temporary transient contact in order to menopause tablet on the resolution bank.Because in fact, temporarily dropping of yarn is a phenomenon machinery rather than electric, yet no matter lacks more, it will continue a hop count magnitude is the time of signa.In contact time, therefore unit C is in and carries out enough position of the signal detection of high numerical value at this section.Detect from first experiment, have been found that numerical value n advantageously is located between 2 and 20, is located between 3 and 10 best according to device of the present invention.
Sum shown in the counter (module 3) is detected by the detector of the state of emergency (module 4), and detector just sends arresting stop S and first caution signal A that control signal is given loom in case infer the threshold value n that the accumulator at counter presets and reached.Before the value of caution sign (module 5)-it is carried out on counter (module 3), checked by signal existence inspection (module 2)-change to 1 from 0 simultaneously.
In fact, when above-mentioned control signal when the detector of the state of emergency (module 4) has sent, loom has been stopped thus, and the value of caution sign (module 5) has been changed to 1, the logic that there is inspection (module 2) in signal is by following change:
If--the existence of a signal is detected, and does not then carry out further operation;
--on the other hand, if not existing of signal is detected, then second caution signal B is issued, or alternatively, already present caution signal A is modified.
Existed inspection (module 2) detected signal not exist by signal, in fact corresponding to a temporary transient state of contact, second caution signal B makes the operator thus, know that not only the trouble that has taken place goes out in what position (the signal A that this information always is in state of activation offers him), and know trouble which kind of type takes place (that is, a temporary transient contact rather than lasting contact).
If since yarn drop on bank-this phenomenon can produce, even when the lasting contact reality of menopause tablet has produced, temporary transient signal do not exist-and produce any oscillation phenomenon, or the slow decay of concussion, the extra function that has the ability to anticipate (being quite analogous to the function that is presented in module 3 and 4), it only provides not exist at signal and is detected m and just sends second caution signal B after the circulation continuously, wherein m is greater than 0, the required time of concussion after being longer than yarn on the decay bank and dropping.
Best, second caution signal B is the form with an interrupted signal lamp.In this case, the work by changing it is from a continuous signal lamp to an interrupted signal lamp, and it can comprise easily and be used for the identical signal lamp of first caution signal A.In this last a kind of situation, clearly, when a lasting contact took place, corresponding thus signal lamp was a continuous type, in case the operator mentions yarn on bank the time, above-mentioned signal lamp will be transformed into a discontinuous signal lamp suddenly; The change of sort signal lamp does not finally produce inconvenience to the operator, and in fact the operator receives that one is further confirmed in this case, the actual menopause tablet that sends of decision caution signal A is operated.
Work as the operator, under the guiding of foregoing indication, finished the reparation of any warp thread that may disconnect or relax, and loom starts again, automatically provide counter (module 3) accumulator and the effectively zero setting of the value of caution sign (module 5) according to electronic-controlled installation of the present invention, said apparatus is set at the state that restarts foregoing action type thus.
The device that not same work-based logic is arranged is provided in according to second embodiment of the invention; this embodiment can successfully be applied to loom; wherein owing to drop on bank, menopause tablet should show high oscillation phenomenon usually, or concussion decay very slowly.In this example, in fact, even the true contact of menopause tablet occurs, very likely signal exist to check that (module 2) find that really the above-mentioned continuous synchronization period n that is enough to stop loom is too late, that is, and and when the cloth of defectiveness during by braiding.So for diverse ways of these situations is studied, and, identical situation is discussed below with reference to the flow chart identical with Fig. 2.
According to this method, exist to check (module 2) when signal and infer that when having a signal of telecommunication (this digital signal value is 1) on the bank, a numerical value 1 is increased to counter; On the contrary, when inferring the signal of telecommunication when it and not having (this digital signal value is 0), a numerical value 1 is deducted from counter (module 3).Therefore above-described signal controlling process continues to reach a predetermined value p up to the accumulator of counter, has promptly detected the number of the circulation of signal existence up to unit C, as above-mentioned value p, is higher than the number of the non-existent circulation of signal that detects.Preferably counter (module 3) resets to zero by the time interval of rule, and preventing numerical value p by the static discharge on any bank, or other electric transient phenomenon has a strong impact on.
The above method is based on following, through verification on the statistics, suppose.At first, a true contact of menopause tablet, even the oscillatory occurences of being subjected to or the influence of oscillatory extinction very slowly also produce, from the contact that begins most, the number that records the sampling circulation of signal existence is higher than the number that records the non-existent sampling circulation of signal.The second, the static discharge on the bank, or other electric transient phenomenon provides, at least in an enough short time range, the number that records the sampling circulation that signal exists is lower than the number that records the non-existent sampling circulation of signal.
Experiment is adjusted the misconnection that numerical value p is easy to differentiate menopause tablet and is touched and truly contact.The selected enough height of numerical value p energy touch in order to differentiate misconnection in true contact, and enough low in order to comprise the temporary transient contact of menopause tablet on the bank.Because in fact, temporarily dropping of yarn is a phenomenon machinery rather than electric, yet no matter lacks more, it will continue, and as what seen, a hop count magnitude is the time of signa.In contact time, therefore unit C is in and carries out enough position of the signal detection of high numerical value at this section.Detect from first experiment according to device of the present invention, have been found that numerical value p is located between 0 and 15 easily, be located at best between 2 and 12, yet signal exists or does not exist the scope that is counted the time wherein not limited especially, and depends on the special state of weaving cotton cloth of loom.In normal the application, above-mentioned time range is made as tens of Milliseconds effectively, easily between 30 to 70 milliseconds, and is preferably between 40 to 60 milliseconds.From above-described, should know the end of scope at any time, as previously defined, if counter (module 3) does not also reach preset value p, it is reset is zero, and is begun in the new counting time range below.
Numeral shown in the accumulator of counter (module 3) is usually by the check of a detector (module 4) of the state of emergency, in case it infers that the threshold value p that presets reaches, it just sends control signal and gives loom arresting stop S and first caution signal A.In a preferred type device, when threshold value p was reached, the accumulator of counter (module 3) was changed to a predetermined counter total head q suddenly, and for example 100 or higher, and signal exists and detects (module 2) and continue to carry out previous function, promptly
Be detected if-signal exists, be increased numerical value 1 in the counter (module 3), but be no more than foregoing full scale value; With
--if signal does not exist and is detected, and is deducted numerical value 1 in the counter (module 3).
Only when counter is returned null value, just send second caution signal B, or already present caution signal A is changed.In fact the range value of counter is determined as the required so high value of complete attenuation that will obtain the menopause tablet vibration in corresponding sample time in the length.The non-existent detection of any signal still continues after counter returns null value, thereby means that without doubt the true contact that detects has at first changed temporary transient contact into, therefore is warned signal B and correctly signals.
Best, second caution signal is the form with an interrupted signal lamp.In this case,, the work by changing it is from a continuous signal lamp to an interrupted signal lamp, and it can comprise easily and be used for the identical signal lamp of first caution signal A.
Work as the operator, under the guiding of foregoing indication, finished the reparation of any warp thread that may disconnect or relax, and loom starts again, automatically provide zero setting to the accumulator of counter (module 3) according to electronic-controlled installation of the present invention, said apparatus is set at the state that restarts foregoing action type thus.
Function in the superincumbent narration in the module 3 has been described as a counter.Yet this function also can be finished by the adder of any kind.For example, in fact a time integral device can be used easily, is preferably in each sampling circulation, and its accumulator is added or deduct one period that is equal to the sampling period.In this situation, when a true contact of menopause tablet had been detected, the full scale value of this integrator can be used directly as a control signal delivering to loom arresting gear S.
It seems clearly how fully to reach its predetermined target from above narration according to device of the present invention.In fact it allow to differentiate definitely the misconnection that is determined by electrostatic phenomenon is touched and since yarn drop on bank, even temporary transient, and the true contact that causes.Said apparatus also allows, even under the situation of temporary transient contact, also can obtain one about the top bank that trouble has taken place, or the indication accurately of bank part, makes it possible to reduce greatly loom downtime and operator's working time.
