Display 47, can be related by action state with yarn clearer 15 etc. by the display of text, symbol, figure etc. Information is notified to operator.The display content of display 47 is controlled by yarn clearer control unit 50.

Cutter 16 has cutter blades as described above, and cutter blades are for example in directly solenoid-activated.Cutter 16 is electrically connected In yarn clearer control unit 50, and it is configured to the shutoff signal cutting continuous strand 10 exported based on yarn clearer control unit 50.

Compressed air solenoid valve 48 is configured at the supply source of compressed air (not shown) (for example, Yarn winding apparatus has Air blower) and above-mentioned first discharge port 151 and the second outlet 152 between path.Compressed air solenoid valve 48 It is electrically connected to yarn clearer control unit 50, and the injection signal valve opening stipulated time exported based on yarn clearer control unit 50, so as to It is enough to spray air from first discharge port 151 and the second outlet 152.By the first discharge port 151, the second outlet 152, with And compressed air solenoid valve 48 constitutes the foreign substance removing apparatus that foreign matter is removed from detection zone 36.

In the present embodiment, the control of yarn clearer control unit 50 recycles to start the above-mentioned yarn that connects in unit control unit 30 Afterwards, compressed air solenoid valve 48 is opened immediately, and sprays air from first discharge port 151 and the second outlet 152.Start The initial yarn 10 for connecing yarn circulation is not imported into detection zone 36, therefore by spraying air at the moment, can prevent yarn The case where flowing of 10 obstruction air.Therefore, it can effectively blow and fly to be present in the foreign matter of detection zone 36 and be removed.

In addition, yarn clearer control unit 50 will according to when yarn 10 does not exist in detection zone 36 institute of sensor unit 35 it is defeated Detected value out and the evaluation acquired is stored in aftermentioned data store 57 with a reference value.The yarn that yarn clearer control unit 50 has The evaluation by being evaluated the state of (measurement) yarn 10 by linear state evaluation section 53 with a reference value compared with detected value.

Next, the electric structure to yarn clearer control unit 50 is illustrated.Yarn clearer control unit 50, which has yarn conditions, to be commented Valence portion (evaluation section) 53, adjustment section (light projector adjustment section) 54, acquisition unit 55, yarn whether there is or not determination unit 56, data store 57, set Determine portion 58 and foreign matter reply processing unit 59.Specifically, yarn clearer control unit 50 is configured to have CPU, ROM, RAM etc. firmly The computer of part is stored with the softwares such as control program in above-mentioned ROM.Moreover, above-mentioned hardware and software collaboration act, so as to Enough making yarn clearer control unit 50 as yarn conditions evaluation section 53, adjustment section 54, acquisition unit 55, yarn, whether there is or not determination units 56, number Processing unit 59 etc. should be acted according to storage unit 57, configuration part 58 and foreign matter.

The above-mentioned yarn circulation that connects starts, and is spraying sky from first discharge port 151 and the second outlet 152 as described above After gas, adjustment section 54 is being adjusted processing (light projector adjustment processing) after a little time.So-called adjustment processing is in yarn 10 do not exist in the state of the detection zone 36 of yarn clearer 15, and adjustment is applied to light-projecting portion 41 in the sensor unit 35 Driving voltage, so that the detected value (specifically, being output voltage) that sensor unit 35 exports becomes defined adjustment and uses base The processing of quasi- value.

Acquisition unit 55 is measured processing.So-called measurement processing refers to: not existing in the detection of yarn clearer 15 in yarn 10 In the state of region 36, sensor unit 35 is controlled in such a way that adjusted processing voltage adjusted is applied to light-projecting portion 41, To obtain the processing of the detected value of 35 reality output of sensor unit.Thus obtained detected value is (specifically, be sensor The output voltage of unit 35) ought to become with the roughly the same value of adjustment a reference value in above-mentioned adjustment processing, but there is also Such as become the value deviated from adjustment a reference value because of the influence of the intrusion of temperature variation, Soft flocks etc. (foreign matter), disengaging etc. The case where.The detected value that acquisition unit 55 obtains is stored in aftermentioned data store 57.

The yarn detected value that whether there is or not determination units 56 to be obtained based on acquisition unit 55 determines that yarn 10 whether there is in yarn clearer 15 Detection zone 36 (in particular, yarn path in detection zone 36) and whether to detection zone 36 (in particular, detection zone Yarn path in domain 36) import yarn 10.Specifically, for yarn whether there is or not for determination unit 56, if sensor unit 35 output voltage is defined threshold value (whether there is or not decision thresholds for yarn) or more, then is determined as that yarn 10 is present in yarn path (having yarn) is determined as that yarn 10 does not exist in yarn path (no yarn) if being far from it.In addition, detection zone 36 be with The space of prescribed level.Yarn path in detection zone 36 can show as the position mobile for yarn 10, that is, upper and lower The position (being the position of some when vertical view: specified position) that a pair of of yarn path guiding piece 131,132 limits.

In the case where being determined as has yarn, whether there is or not determination units 56 (yarn clearer control unit 50) by the signal of the purport for yarn (having yarn signal) exports to unit control unit 30.Whether unit control unit 30 is using from yarn clearer control unit 50 having had input yarn Line signal judges whether yarn 10 by the above-mentioned yarn circulation that connects normally is placed in detection zone 36.But it also deposits The case where yarn has not exported yarn signal whether there is or not determination unit 56, it is described in detail later.

Data store 57 has the storage region for capableing of more new content, for example, the volatibility or non-by that can rewrite Memory (such as RAM, EEPROM) of volatibility etc. is realized.The data store 57 can be stored for controlling yarn clearer 15 Various parameters etc..

Specifically, multiple measured values obtained by acquisition unit 55 can be stored in advance in data store 57.That is, acquisition unit 55 not instead of only implement primary above-mentioned measurement processing, the yarn in the detection zone 36 for importing yarn clearer 15 up to yarn 10 It is anti-every predetermined time interval during (position of yarn 10 determination in yarn path: positioning) of line passage Implement multiple measurement processing again, and obtains detected value every time.Data store 57 being capable of chronologically sequential storage stipulated number Candidate value of the data of detected value as aftermentioned evaluation a reference value.

In addition, data store 57 can store foreign matter determination range and become the base reference of reference of the foreign matter determination range Value, wherein foreign matter determination range is in the case where yarn 10 does not exist in detection zone 36 of yarn clearer 15 to detect fibre Tie up the range that (foreign matters) such as bits is determined relative to intrusion and the disengaging of detection zone.In addition, foreign matter determination range etc. is at it It is explained in detail afterwards using the chart of Fig. 6 etc..

In addition, data store 57 can store the upper limit value and lower limit value of normal range (NR), wherein normal range (NR) indicates The range that detected value usually should be locating in the case where yarn 10 does not exist in detection zone 36 of yarn clearer 15.The normal model The upper limit value and lower limit value enclosed are the threshold value being preset, and normal range (NR) is by the threshold definitions.The normal range (NR) is with its width The mode bigger than the amplitude of foreign matter determination range is spent to be determined.

In addition, data store 57 can store as yarn whether there is or not determination unit 56 determine the presence or absence of yarn 10 boundary and Whether there is or not decision thresholds for the threshold value that is, yarn used.As the yarn, whether there is or not decision thresholds, set the upper limit than normal range (NR) It is worth big value.

In addition, data store 57 can also store the setting of the evaluation a reference value determined by aftermentioned configuration part 58 Value.Above-mentioned yarn conditions evaluation section 53 is by compared with the evaluation a reference value, to evaluate the state of yarn 10.Specifically, The voltage that is set as evaluation a reference value in the state of detection zone 36 for entering yarn clearer 15 in yarn 10 from biography The average value for the difference in voltage that sensor cell 35 obtains, by the monitoring of yarn 10 (for example, based on the average boldness of yarn 10 It calculates).

Configuration part 58 is based on detected value (the evaluation a reference value for being obtained by acquisition unit 55 and being stored in data store 57 Candidate value) in satisfaction as defined in condition detected value come determine (calculating) evaluation use a reference value value, using the result as newly Setting value be stored in data store 57.In the present embodiment, the setting value of new evaluation a reference value is stored again It is known as " benchmark amendment " in the case where data store 57.

Next, the yarn evaluation precision (yarn monitoring precision) for the sensor unit 35 for making present embodiment is reduced Two principal elements are illustrated.One in two principal elements is temperature variation etc. with LED used by light-projecting portion 41 For the variation of the environment of representative, remaining one is the foreign matter for invading detection zone 36.

Hereinafter, explaining in detail.As shown in the embodiment, having adjustment section 54, acquisition unit 55, Yi Jishe Determine in the yarn clearer 15 in portion 58, before the evaluation for starting yarn 10, usually carries out following such preparation work.That is, firstly, adjusting Whole 54 accurately adjust sensor list by above-mentioned adjustment processing in the state that yarn 10 does not exist in detection zone 36 The value for the projection quantity of the light-projecting portion 41 of member 35.Then, acquisition unit 55 obtains biography in the state that yarn 10 does not exist in detection zone 36 The detected value of sensor cell 35, configuration part 58 are based on the detected value and set evaluation a reference value.

After above-mentioned preparation work, yarn 10 is imported to detection zone 36, yarn winding unit 1 starts to wind, from And the state of yarn 10 is evaluated by yarn conditions evaluation section 53.At this point, light-projecting portion 41 is just past above-mentioned preparation work The driving voltage of adjustment is driven, in addition, the benchmark of the evaluation as yarn 10, is able to use and sets in above-mentioned preparation work Fixed evaluation a reference value.By above such control, the precision when state of evaluation yarn 10 can be improved.

But detection zone is imported to by 10 reality of yarn in the stage for being adjusted processing and setting evaluation a reference value During 36, a possibility that there is also the environmental changes such as temperature, humidity.In particular, the yarn clearer 15 of present embodiment is optics The yarn monitoring device of formula, light-projecting portion 41 are made of LED.Thus, for example after powering on to yarn clearer 15, During at the time of importing detection zone 36 to yarn 10 at the time of being adjusted processing and set evaluation a reference value, exist The temperature of LED rises, the feelings changed so as to cause the light quantity irradiated from light-projecting portion 41 by the temperature variation of the LED (thermal change is dynamic) Condition.

Even if being adjusted processing and further setting evaluation a reference value, detected after setting up to yarn 10 imports The light quantity of light-projecting portion 41 also changes during region 36, then error correspondingly is generated in the evaluation of the state of yarn 10, So not preferably.Accordingly, it is considered to not instead of adjustment processing after, yarn 10 import detection zone 36 it is tight preceding at the time of take It must be used to determine the detected value of evaluation a reference value.So, the influence that can reduce temperature variation etc., thus allows for Accurate yarn evaluation.

However there are following situations, it may be assumed that although can by the decisive time for setting evaluation a reference value as described above Reduce the influence of temperature variation etc., but effect and insufficient.That is, it needs to consider that Soft flocks generated in Yarn winding apparatus etc. are different Object invades a possibility that detection zone 36.

For example, sensor unit 35 is different after being adjusted processing and in the case where foreign matter invades detection zone 36 Influence of the detected value exported after object intrusion by the foreign matter, therefore can not accurately evaluate the state of yarn 10.In addition, working as Foreign matter comes into the state of detection zone 36 be adjusted processing in the case where, if foreign matter is de- from detection zone 36 later From then the detected value of sensor unit 35 is affected, therefore still can not accurately evaluate the state of yarn 10.

In this aspect, in the yarn clearer 15 of present embodiment, it is configured to from processing is adjusted up to yarn 10 imports Detection zone 36, detection foreign matter relative to intrusion, the intrusion of detection zone 36 foreign matter from the disengaging of detection zone 36, and carry out Various processing (hereinafter, often referred to as foreign matter reply is handled).

In addition, the case where foreign matter invades detection zone 36, in the case that foreign matter is detached from from detection zone 36, detected value ratio More sharp change.On the other hand, in the case where the light quantity of light-projecting portion 41 is reduced because of temperature variation, detected value is slower Ground changes.The yarn clearer 15 of present embodiment utilizes the situation, can by the variation (intrusion/disengaging) of the intrusion state of foreign matter and Temperature variation is clearly distinguished and is detected.

Then, the control referring to the chart of Fig. 6~Figure 10 to the yarn clearer control unit 50 of the present embodiment of various situations It is described in detail.

As described above, until detecting that yarn 10 imports detection zone 36, being obtained after adjustment section 54 is adjusted processing Portion 55 obtains detected value repeatedly at desired intervals.The chart of Fig. 6 is shown using horizontal axis as the time, is detection with the longitudinal axis Value, and the detected value obtained respectively at t1~t25 moment.In addition, the chart of Fig. 6 shows foreign matter determination range, normal together Whether there is or not decision thresholds for range, yarn.

Acquisition unit 55 the t1 moment, the t2 moment ... obtain detected value repeatedly.Detected value obtained is as evaluation base The candidate value of quasi- value is successively stored in data store 57.

In addition, the initial detected value for obtaining moment that is, t1 acquirement in adjustment after treatment is aftermentioned as determining The a reference value of foreign matter determination range is stored in data store 57.

Then, foreign matter reply processing unit 59 is based on a reference value, and setting the detected value that next (t2 moment) obtains should fall The range that is, foreign matter determination range entered.The foreign matter determination range is in order to detect foreign matter intrusion detection zone 36 and from detection Region 36 is detached from and the range of setting, and above-mentioned a reference value is determined as median.

Then, when acquisition unit 55 is when obtaining detected value at the t2 moment, foreign matter reply processing unit 59 determines the inspection specifically obtained Whether measured value enters above-mentioned foreign matter determination range.In the example of fig. 6, the detected value at the t2 moment becomes with the inspection at t1 moment More than the lower limit value of the foreign matter determination range on the basis of measured value (a reference value) and below upper limit value.Therefore, foreign matter copes with processing unit 59 are specifically stored in data store 57 using the detected value at t2 moment as a reference value again, and again based on new a reference value Secondary setting foreign matter determination range, therefore, it is determined that whether the detected value at t3 moment enters the foreign matter determination range.At above judgement Reason the t4 moment, the t5 moment ... repeatedly, along with this, foreign matter determination range is also updated successively.

In addition, being directed to each detected value, the judgement based on above-mentioned foreign matter determination range is not only carried out, is also carried out other Determine.Specifically, adjustment section 54 judges whether the detected value enters in yarn 10 relative to the detected value obtained at each moment The normal model predetermined in the state of detection zone 36 as the range of detected value that usually should be locating is not existed in It encloses.In addition, whether there is or not determination units 56 relative to the detected value obtained at each moment for yarn, judge whether the detected value become as defined in Whether there is or not more than decision threshold for yarn.In addition, above-mentioned normal range (NR), which is typically set at, judges model comprising above-mentioned foreign matter in inside The case where enclosing, but exceeding there is also foreign matter determination range from normal range (NR).In addition, whether there is or not decision thresholds to be set as above-mentioned yarn The value being detached from from above-mentioned foreign matter determination range.

Finally, since yarn 10 has imported detection zone 36, therefore at the t25 moment, the detected value that acquisition unit 55 obtains is big Width increases.It is more than that whether there is or not decision thresholds for yarn, therefore whether there is or not determination units 56 to be determined as yarn for yarn in the detected value that the t25 moment obtains Line 10 has imported detection zone 36 (having yarn).At this point, configuration part 58 will obtain before tight at the time of being determined as has yarn Detected value (in the example of fig. 6, being the detected value at t24 moment) is set as evaluation a reference value.Benchmark amendment is carried out as a result, If then yarn 10 starts to move, yarn conditions evaluation section 53 evaluates yarn 10 based on the evaluation being set a reference value.

In addition, in the example of fig. 6, because of the influence of the temperature variation of above-mentioned light-projecting portion 41, being detached from shown in fig. 6 normal The case where range, is simultaneously less intense, but detected value shows slow increase trend.Because of the influence, when treated for adjustment Carve that is, the detected value at the place t1 be judged to having yarn it is tight preceding at the time of that is, the detected value of t24 etc. in, generation is to a certain degree Deviate from.In this aspect, the configuration part 58 of present embodiment uses the inspection with the t24 moment close at the time of being judged to having yarn Measured value can reduce the influence of above-mentioned temperature variation as evaluation a reference value, so as to be commented by yarn conditions Accurately evaluate yarn 10 in valence portion 53.

But about evaluation a reference value, it is not limited to use the detected value at t24 moment as described above.For example, can be with Use from detected value at the time of tracing defined difference at the time of being judged to having yarn as evaluation a reference value, in addition, Average value can be calculated based on multiple detected values and the average value is set as evaluation a reference value.

Next, the case where elapsing as shown in Figure 7 to detected value is illustrated.In the example of fig. 7, t1~t3 moment How detected value does not show variation, but during t3~t4, and foreign matter invades above-mentioned detection zone 36, as a result, the t4 moment Detected value suddenly increases a little, more than the upper limit value of the foreign matter determination range of the detected value (a reference value) based on the t3 moment.

Even if in the case of fig. 7, acquisition unit 55 is also identicallyly as Fig. 6, the t1 moment, the t2 moment ... obtain repeatedly Detected value obtained is successively stored in data store 57 by detected value.In addition, base The update of quasi- value and foreign matter determination range also with Fig. 6 the case where carry out identically.

But the detected value at t4 moment is more than the upper limit value of foreign matter determination range, therefore foreign matter reply processing unit 59 stops The update of a reference value and foreign matter determination range.Therefore, determining whether the detected value at next t5 moment enters not is with t4 But the foreign matter determination range on the basis of the detected value at t3 moment (a reference value).

In addition, the detected value is not used as and comments in the case where detected value is detached from as the t4 moment from foreign matter determination range The candidate Value Data of valence a reference value and be stored in storage unit 57, therefore will not will as evaluation a reference value and by It uses.Therefore, the irregular detected value using above-mentioned cataclysm is reliably prevented from as evaluation a reference value.

Foreign matter continues to be stranded in detection zone 36, therefore the detected value of the detected value and t4 at the t5 moment also and less becomes Change, or more than the upper limit value of the foreign matter determination range based on the detected value (a reference value) at the t3 moment, later the t6 moment, The t7 moment ... it is all the same.Foreign matter copes with t22 of the processing unit 59 after the state continues the defined time (foreign matter judges the time) Moment is judged as that foreign matter has invaded (a possibility that correctness of yarn evaluation is reduced because of the influence of the foreign matter increasing of detection zone 36 It is high).

Then, yarn 10 imports detection zone 36, and with Fig. 6 the case where is identical, and detected value is dramatically increased at the t25 moment And as yarn, whether there is or not more than decision threshold.Whether there is or not determination units 56 to be judged as having yarn for yarn, but is judged as allotrylic different Object reply processing unit 59 prevents yarn, and whether there is or not the outputs of determination unit 56 yarn signal.As a result, whether there is or not 56 (clearings of determination unit for yarn Device control unit 50) do not export yarn signal.

Herein, the first yarn capture device 12 and the second yarn capture device 13 is made to turn to Fig. 3's from the state of Fig. 1 The unit control unit 30 of state is constituted are as follows: based on having yarn signal confirmation yarn 10 to import clearly from yarn clearer control unit 50 The detection zone 36 of yarn device 15.Specifically, even if practical yarn 10 has imported detection zone 36, foreign matter reply processing unit 59 does not also make Whether there is or not the outputs of determination unit 56 to have yarn signal (that is, yarn 10 is not being imported detection zone by yarn clearer control unit 50 just for yarn It is acted when 36).

Even if the standby stipulated time, will not input from yarn clearer control unit 50 has yarn signal, because of this element control unit 30 are judged as that the first yarn capture device 12, the second yarn capture device 13 capture unsuccessfully etc. yarn 10, and make 10 phase of yarn Importing failure for the detection zone 36 of yarn clearer 15.Therefore, unit control unit 30 is without connecing based on yarn splicing device 14 Yarn operation and stop, make the first yarn capture device 12 and the second yarn capture device 13 returning briefly to the state of Fig. 1, and again Secondary re-start connects yarn circulation.Thereby, it is possible to avoid accurately carrying out yarn evaluation because of the influence of foreign matter in yarn clearer 15 In the state of start yarn 10 winding.

At the initial stage for connecing yarn circulation re-started, the driving compressed air solenoid valve 48 of yarn clearer control unit 50, and into Exercise the processing (foreign matter removing processing) that air is sprayed from first discharge port 151 and the second outlet 152.Therefore, intrusion inspection The foreign matter for surveying region 36 is blown that a possibility that winged is higher by air, therefore can expect not the adjustment processing to next time, evaluation base The setting of quasi- value, which is given, to be negatively affected.

After spraying air in a manner of the foreign matter to remove detection zone 36, in yarn clearer control unit 50, adjustment section 54 It is adjusted processing again, then, acquisition unit 55 obtains the detected value of sensor unit 35 repeatedly again.At this point, for example examining In the case that measured value elapses as shown in Figure 6 and yarn 10 is imported detection zone 36, evaluation is determined as described above with a reference value, To which yarn conditions evaluation section 53 evaluates yarn 10 with a reference value using the evaluation.

As described above, in the yarn clearer of present embodiment 15, foreign matter copes with processing unit 59 and is being based on sensor unit The variation of the detected values of 35 outputs and in the case where being judged as that foreign matter has invaded detection zone 36, carry out the following processing that (foreign matter is answered To processing), it may be assumed that preventing yarn, whether there is or not determination units 56 to be judged to there is yarn and exporting having yarn signal therewith.As a result, along with It re-starts and connects yarn circulation, carry out detection zone 36 and spraying air from first discharge port 151 and the second outlet 152 Cleaning and the adjustment again (therefore, also re-start benchmark amendment) of value for the projection quantity is carried out by adjusting portion 54.

Therefore, foreign matter reply processing unit 59 also can be actually by spraying from first discharge port 151 and the second outlet 152 Out air and carry out the removing of foreign matter, and carry out the adjustment again of value for the projection quantity.As a result, it is possible to be adjusted in value for the projection quantity, benchmark When amendment, prevent bring due to foreign matter from negatively affecting well, therefore yarn conditions evaluation section 53 can accurately evaluate yarn The state of line 10.

Next, the case where elapsing as shown in Figure 8 to detected value is illustrated.The example of Fig. 8 shows the inspection at t4 moment Measured value suddenly increase a little, the detected value of the detected value that the t5 moment is roughly the same with the t4 moment, but t6 moment reduce to t3 Roughly the same value.The situation shows foreign matter and invades detection zone 36 during t3~t4, but the foreign matter is not detained for a long time, And it is detached from during t5~t6.

If being illustrated with the relationship with foreign matter determination range to the passage of above-mentioned detected value, the detected value at t4 moment More than the upper limit value of the foreign matter determination range determined on the basis of the detected value at t3 moment, the detected value at t5 moment is also in the same manner More than the upper limit value of the foreign matter determination range determined on the basis of the detected value at t3 moment, but the detected value at t6 moment becomes different More than the lower limit value of object determination range and below upper limit value.That is, continuing to exceed the time of the upper limit value of foreign matter determination range than upper The foreign matter stated judges that the time (referring to Fig. 7) is short.Therefore, in this case, foreign matter reply processing unit 59 is not judged as that foreign matter invades (accuracy of yarn evaluation increases because of a possibility that influence of foreign matter reduces).

As described above, the detected value at t6 moment becomes the defined foreign matter on the basis of the detected value (a reference value) at t3 moment More than the lower limit value of determination range and below upper limit value.Therefore, it is new that foreign matter, which copes with processing unit 59 with the detected value at the t6 moment, A reference value, and determine foreign matter determination range again in such a way that a reference value becomes benchmark, and update and a reference value and different The storage content of the related data store 57 of object determination range.In addition, the detected value at t4 and t5 moment is detached from foreign matter judgement Range, therefore it is stored in data store 57 not as the candidate value of evaluation a reference value, but return to foreign matter in detected value and sentence T6 moment in disconnected range, the detected value are stored in data store 57.After, foreign matter reply processing unit 59 monitors whether again The secondary sharply variation (that is, the variation for being detached from foreign matter determination range) for detected value occur.

In the example of fig. 8, after the t6 moment, until during yarn 10 imports before detection zone 36, the non-table of detected value Reveal biggish variation.If yarn 10 imports detection zone 36, detected value is significantly increased at the t25 moment and whether there is or not sentence as yarn Determine threshold value or more, then whether there is or not determination units 56 to be judged to having yarn for yarn.Foreign matter reply processing unit 59 is not determined as that foreign matter invades, because This yarn exports as usual whether there is or not determination unit 56 yarn signal, so that configuration part 58 sets the detected value at t24 moment For evaluation a reference value.Then, yarn conditions evaluation section 53 starts along with the winding of yarn 10 and monitors yarn 10.

As above, although being considered as that there is no different in the case where being detached from foreign matter temporarily intrusion 36 short time of detection zone The intrusion of object, therefore without the foreign matter reply processing based on foreign matter reply processing unit 59, and carry out usually such processing.Cause This, can prevent from carrying out meaningless foreign matter reply processing, to improve the efficiency of Yarn winding apparatus.

In addition, detected value temporarily sharp increases but is possible to the phenomenon that recovery in a short time by foreign matter as shown in Figure 8 Principal element in addition causes.For example, there are following situations: when carrying out above-mentioned doffing operation, no matter doffing operation itself Whether it is normally carried out, the detected value of sensor unit 35 is highly unstable, and is temporarily disengaged from above-mentioned foreign matter determination range.So And in the case where doffing operation, above-mentioned variation, which judges the time more closer to above-mentioned foreign matter, chronically to be continued, and becomes Dynamic detected value usually restores in a short time.Therefore, it can prevent from carrying out unnecessary foreign matter in common doffing operation Reply processing, therefore also can be improved the efficiency of Yarn winding apparatus in the sense that.

Next, the case where elapsing as shown in Figure 9 to detected value is illustrated.The example of Fig. 9, which is shown, to be strongly suggested that The case where influence of the temperature variation of light-projecting portion 41, and after adjustment processing, with Fig. 6 the case where compared with detected value show strongly Increase tendency.But each incrementss of detected value are in above-mentioned foreign matter determination range.

The upper limit value that the detected value increased eventually exceeds normal range (NR) is obtained every time.It detects and obtains at the t19 moment Detected value is more than that the adjustment section 54 of the upper limit value of normal range (NR) is adjusted processing again.In addition, along with this, measurement processing with And benchmark amendment re-starts after adjustment is handled.

It can be by adjusting portion 54 again in the case where generating the temperature variation that can not be allowed by above-mentioned processing It is adjusted processing.That is, the influence of temperature variation is forcefully excluded by the driving voltage for adjusting light-projecting portion 41 again, from And it can accurately evaluate the state of yarn 10.

In addition, in the above example, in detected value even in the case where being once more than the upper limit value of normal range (NR), also again It is secondary to be adjusted processing.However, replacing, judge time in the continuous defined adjustment of detected value (light projector adjustment judges the time) In the case where upper limit value more than normal range (NR), also it is configured to adjustment section 54 and is adjusted processing again.In this case, It can prevent from for example causing to carry out unnecessary adjustment processing because of the noise that detected value is showed.

However, because of caused by temperature variation shown in Fig. 9 detected value increase, and invade because of Fig. 7, foreign matter shown in Fig. 8 The increase of detected value caused by entering has different characteristics.That is, the case where detected value increases because of the influence of temperature variation Under, it is relatively small compared with allotrylic situation relative to the incrementss of the detected value at moment last time and gentle, as long as therefore Fully shorten the time interval for obtaining detected value, is then extremely hard to the case where discovery is detached from above-mentioned foreign matter determination range.It is real On border, in the example of figure 9, each detected value of the detected value before the t19 moment is more than the upper limit value of normal range (NR) is once Without departing from foreign matter determination range, therefore foreign matter reply processing unit 59 is not judged as that foreign matter invades.Accordingly, at without foreign matter reply It manages (processing that prevention has the output of yarn signal).

As above, in the present embodiment, it is configured to work as and variation sharply, and the shape after the variation is temporarily presented in detected value In the case that state has continued the stipulated time, foreign matter should be judged as that the intrusion state of foreign matter changes and carries out different to processing unit 59 Object reply processing.Therefore, it can prevent the influence for being for example mistakenly judged as temperature variation from carrying out depending on foreign matter unnecessary Foreign matter cope with processing the case where.

Next, the case where elapsing as shown in Figure 10 to detected value is illustrated.In the example of Figure 10 and the case where Fig. 7 On the contrary, lower limit value of the detected value at t4 moment lower than the foreign matter determination range on the basis of the detected value (a reference value) of t3, and Continue during the situation is long.The situation is thought of as being adjusted processing in the state that foreign matter invades detection zone 36, then, different Object is stranded in detection zone 36 before the t3 moment but is detached from during t3~t4.

In this case, foreign matter should carry out the processing roughly the same with the case where Fig. 7 to processing unit 59.Specifically, t4 The detected value at moment is lower than the lower limit value of the foreign matter determination range of the detected value (a reference value) based on the t3 moment, therefore foreign matter is coped with The update of the stopping foreign matter determination range of processing unit 59.Accordingly, with respect to the detected value at next t5 moment, determine whether to enter The foreign matter determination range of the detected value (a reference value) at t3 moment.

In the example of Figure 10, the foreign matter determination range of the detected value at t5 moment also below the detected value based on the t3 moment Lower limit value, the state the t6 moment, the t7 moment ... continue.It is (different in the state continuous stipulated time that foreign matter copes with processing unit 59 Object judges the time) after the t22 moment, be judged as foreign matter from detection zone 36 be detached from.Therefore, foreign matter reply processing unit 59 and judgement The case where for allotrylic Fig. 7, is identical, even if yarn 10 is imported detection zone 36, also preventing yarn, whether there is or not determination unit 56 is defeated There is yarn signal out, connects yarn circulation to promote to re-start.Thereby, it is possible to adjustment is re-started in the state that foreign matter is detached from Processing, benchmark amendment, therefore yarn conditions evaluation section 53 can accurately evaluate the state of yarn 10.

Next, referring to Fig.1 1 flow chart to the adjustment section 54 of yarn clearer control unit 50, acquisition unit 55, whether there is or not sentence for yarn The specific processing of the progress such as processing unit 59 should be illustrated by determining portion 56, configuration part 58 and foreign matter.

Other than carrying out adjustment processing and measurement processing etc. shown in Figure 11 when the power supply of yarn clearer 15 is connected, whenever Yarn 10 disappears from the detection zone 36 of yarn clearer 15 due to certain situations are broken and carries out above-mentioned connecing when yarn recycles and also execute Adjustment processing and measurement processing etc. shown in Figure 11.It is monitored in addition, the case where so-called yarn 10 is broken is included in yarn clearer 15 The case where finding above-mentioned yarn defect when yarn and utilizing 16 cutting continuous strand 10 of cutter, package 20 become full volume and utilize cutter The case where the case where 16 cutting continuous strand 10 and generation broken yarn.

As above be continually adjusted processing and measurement processing, thus even if there are the variation of ambient enviroment, dirt to The attachment etc. of the light-projecting portion 41 of yarn clearer 15, acceptance part 42 etc., also can steadily carry out the monitoring of yarn 10.In addition, as above It is described, at the initial stage for connecing yarn circulation, air is sprayed from first discharge port 151 and the second outlet 152, thus starts Figure 11's Processing, therefore can prevent from being adjusted processing and measurement processing etc. in the state that foreign matter invades detection zone 36.

In the state that yarn 10 does not exist in detection zone 36 of yarn clearer 15, if starting the processing of Figure 11, first The adjustment processing based on adjustment section 54 is carried out, to adjust the driving voltage of the light-projecting portion 41 of sensor unit 35 as described above (step S101).If processing terminate for adjustment, foreign matter intrusion change flag is initialized as 0 processing (step S102). Then, the processing of acquirement repeatedly (step S103~S110) of the detected value based on acquisition unit 55 is immediately begun to.

Specifically, the control in such a way that adjusted processing driving voltage adjusted is applied to light-projecting portion 41 of acquisition unit 55 Sensor unit 35 processed, to obtain the detected value (above-mentioned measurement processing, step S103) of 35 reality output of sensor unit. Then, yarn whether there is or not determination unit 56 determine detected value that acquisition unit 55 obtains whether become above-mentioned yarn whether there is or not decision threshold with Upper (step S104).Detected value lower than yarn whether there is or not in the case where decision threshold, adjustment section 54 determine the detected value whether into Enter normal range (NR), i.e. whether detected value is more than the lower limit value of normal range (NR) and is less than upper limit value (step S105).It is in detected value In the case where more than the upper limit value of normal range (NR), it is contemplated that generate the temperature variation that can not be allowed, therefore return step S101.Its As a result, adjustment section 54 carries out adjusting again and re-starting later processing for value for the projection quantity.

In the judgement of step S105, in the case where detected value is more than the lower limit value of normal range (NR) and is less than upper limit value, Foreign matter copes with processing unit 59 and determines the foreign matter determination range whether detected value determines in the detected value (a reference value) based on last time Interior (step S106).In the case where detected value is in foreign matter determination range (that is, more than the lower limit value for foreign matter determination range And in upper limit value situation below), the detected value specifically obtained is set as a reference value and is stored in number by foreign matter reply processing unit 59 Foreign matter determination range is determined again and is stored in 57 (step of data store according to storage unit 57, and based on a reference value S107).Also, acquisition unit 55 is using the detected value specifically obtained as the candidate value for being used to evaluate with the setting of a reference value, and with Said reference value is individually stored in data store 57 (step S108).

In the judgement of step S106, in the case where being judged to being detached from foreign matter determination range (that is, judging lower than foreign matter The lower limit value of range, or more than in the case where upper limit value), foreign matter copes with processing unit 59 and further determines to be detached from step S109 Whether the state of the foreign matter determination range continues the stipulated time (that is, above-mentioned foreign matter judges the time).Model is judged being detached from foreign matter The state enclosed has continued in the case that foreign matter judges the time, and foreign matter reply processing unit 59, which is judged as, produces foreign matter intrusion or de- From, and foreign matter intrusion change flag is set as 1 (step S110), return step S103.In the judgement of step S109, de- In the case that the time that the state of divorced object determination range continues judges the time less than foreign matter, keep foreign matter invading change flag Remain 0 state (skip and foreign matter is invaded into the step S110 that change flag is set as 1), return step S103.

In the judgement of step S104, detected value be yarn whether there is or not more than decision threshold in the case where, investigation foreign matter invade Enter the state (step S111) of change flag.In the case where foreign matter intrusion change flag is 0, it is meant that not by foreign matter reply Reason portion 59, which is judged as, produces intrusion/disengaging of foreign matter.Therefore, in this case, configuration part 58 is based on acquisition unit 55 in step The detected value of data store 57 is stored in S108 to set evaluation a reference value (step S112).Specifically, configuration part 58 by it is in multiple detected values of the column sequential storage on time in data store 57, be judged to having yarn at the time of it is tight before take The newest detected value obtained, is set as evaluation a reference value, and be stored in data store 57.Then, whether there is or not determination units for yarn 56 outputs have yarn signal (step S113).Input has the unit control unit 30 of yarn signal to carry out being based on connecing as needed immediately Yarn feeding device 14 connects yarn operation, then, starts based on the winding of the yarn 10 of winder 18.Yarn conditions evaluation section 53 is based on new The value of evaluation a reference value evaluated (step S114) in the mobile yarn 10 of detection zone 36.

In the judgement of step S111, in the case where foreign matter intrusion change flag is 1, it is meant that handled by foreign matter reply Portion 59, which is judged as, produces intrusion/disengaging of foreign matter.Therefore, whether there is or not the outputs of determination unit 56 for foreign matter reply processing unit 59 prevention yarn What should usually be exported has yarn signal, stops (step S115) in this state.As a result, even if being actually placed with yarn 10 And yarn 10 is made to be present in and (be located at) detection zone 36, yarn clearer 15 also acts in such a way that yarn 10 is not present.Unit control Even if the standby stipulated time of portion 30, also not inputted yarn signal, it is accordingly regarded as the detection zone for making yarn 10 import yarn clearer 15 Domain 36 fails, and connects yarn circulation to re-start.At the initial stage for connecing yarn circulation newly started, from first discharge port 151 and the Two outlets 152 spray air, therefore can be blown foreign matter invades detection zone 36 and fly and remove.Then, from most Just re-start processing shown in the process of Figure 11.

By above processing, the yarn conditions evaluation section 53 of yarn clearer control unit 50 can exclude invading for foreign matter well The influence of the temperature variation of the influence and light-projecting portion 41 that enter/be detached from etc., so as to accurately evaluate the state of yarn 10.

In addition, at the time of foreign matter intrusion change flag is set as 1 (step S110), or do not exported yarn signal and At the time of stopping (step S115), controls and produce intrusion/disengaging of foreign matter for display lamp 46, the display of display 47.As a result, can Enough exceptions for notifying operator understandablely because of detected value caused by foreign matter.

In addition, describing judge whether detected value enters foreign matter and judge model in step s 106 in the flow chart of Figure 11 It encloses, but in fact, judges whether detected value is more than the upper limit value of foreign matter determination range, the lower limit for whether being less than foreign matter determination range Whether value is the lower limit value of foreign matter determination range or more and upper limit value or less.Moreover, being configured to judge in detected value more than foreign matter In the case where the upper limit value of range, allotrylic purport is shown in display 47, is less than foreign matter determination range in detected value Lower limit value in the case where, by foreign matter be detached from purport be shown in display 47.Therefore, it can clearly notify that operator is It is abnormal because of caused by the intrusion of foreign matter, or because abnormal caused by being detached from.

In addition, foreign matter foreign matter that processing unit 59 carries out in the present embodiment reply processing should directly be prevented yarn whether there is or not The output of determination unit 56 has yarn signal, thus realized by the output that prevention has yarn signal from first discharge port 151 and The air of second outlet 152 sprays, the adjustment again of value for the projection quantity (therefore, in above-mentioned foreign matter reply processing, will not be defeated Foreign body detection signal as foreign matter intrusion signal/foreign matter separating signal out).However, even if being above-mentioned structure, foreign matter reply Processing unit 59 also can actually grasp the ejection for carrying out air or carry out the adjustment again of value for the projection quantity.Certainly, at foreign matter reply The foreign matter reply processing that reason portion 59 (yarn clearer control unit 50) carries out may be the signal that air will be sprayed to detection zone 36 The processing that (foreign matter removes and requires signal) exports to compressed air solenoid valve 48.In addition, can also be in foreign matter reply processing Comprising after removing foreign matter in a manner of making adjustment section 54 be adjusted processing again direct output signal processing.

In addition, should handle the foreign matter reply that processing unit 59 carries out as foreign matter, in addition to preventing yarn, whether there is or not determination units 56 Output has except yarn signal, or on this basis, can also be changed to export above-mentioned foreign body detection signal.For example, energy It is enough to consider that being configured to foreign matter reply processing unit 59 is sent to unit control unit 30 for foreign matter intrusion signal/foreign matter separating signal, connects The unit control unit 30 for receiving the signal makes to be re-started based on the connecing yarn job abort of yarn splicing device 14 and connect yarn circulation (that is, resistance Only winding restores).

The foreign matter reply that processing unit 59 carries out should be handled as foreign matter, in addition to this also there are various considerations, for example, can The winding for considering that output prevents the winding of winder 18 from starting prevents signal.In addition, when the yarn signal that connects that request connects yarn is connecing yarn In the case that the midway of circulation is entered, in the Component units control unit 30 in a manner of being re-started since initially and connect yarn circulation Afterwards, foreign matter, which should can also carry out processing unit 59 this connecing processing that yarn signal is exported to unit control unit 30 as foreign matter, copes with Processing.Thereby, it is possible to the intrusion relative to foreign matter/disengagings to carry out various replies.

In addition, as shown in figure 12, can also be determined as the range that foreign matter determination range becomes fixed.In the chart of Figure 12 In example, foreign matter determination range is defined as on the basis of the adjustment a reference value of above-mentioned adjustment processing, has defined width. In the variation, even if the detected value that acquisition unit 55 obtains changes, foreign matter determination range does not also change and constant.In addition, In the example of Figure 12, above-mentioned normal range (NR) is set as including foreign matter determination range, and wider than the foreign matter determination range.

In the example for the Figure 12 for being determined as that foreign matter determination range is made to become fixed range, it becomes difficult to distinguish detect temperature in ground Change intrusion/disengaging with foreign matter.But in the unquestioned situation of temperature variation, for example, being connect to yarn clearer 15 Under the case where energization source passes through the time, the case where using high performance LED as light-projecting portion 41 etc., even if by foreign matter Determination range be determined as be it is fixed, can also detect intrusion/disengaging of foreign matter well.

As shown above, the yarn clearer 15 of present embodiment has light-projecting portion 41, acceptance part 42 and yarn clearer control unit 50.Light-projecting portion 41 to can be mobile for yarn 10 36 projection light of detection zone.The receiving of acceptance part 42 is projected from light-projecting portion 41 Light, and export electric signal corresponding with light income.Have in the input of yarn clearer control unit 50 corresponding with the light income of acceptance part 42 Detected value.Yarn clearer control unit 50 has yarn conditions evaluation section 53, adjustment section 54 and foreign matter reply processing unit 59.Yarn State evaluation portion 53 is present in the state of the yarn 10 of detection zone 36 based on detected value evaluation.Adjustment section 54 is not deposited in yarn 10 It is in the state of detection zone 36, carries out the driving controlling value for adjusting light-projecting portion 41 in such a way that detected value becomes specified value Adjustment processing.Foreign matter copes with processing unit 59 in the state that yarn 10 does not exist in detection zone 36, and continuous in detected value In the case that defined foreign matter judges that the time is detached from defined foreign matter determination range, foreign matter reply processing is carried out.Adjustment section 54 exists Yarn 10 does not exist in the state of detection zone, and is detached from above-mentioned detected value with wider than the width of foreign matter determination range Width the range of detected value that is preset of mode that is, normal range (NR) in the case where, be adjusted processing again.

The detected value that if yarn 10 does not exist in the state of detection zone 36 as a result, continuously as defined in foreign matter judge the time It is detached from foreign matter determination range, then is judged as that the intrusion state of foreign matter has variation, and carries out defined foreign matter judgement processing, therefore Intrusion/disengaging of foreign matter can be dealt adequately with.In addition, with detected value, continuously defined foreign matter judges that the time is detached from foreign matter judgement Range is condition, therefore for example, even if in common doffing operation input yarn clearer control unit 50 detected value it is unstable, It can prevent from being mistakenly judged as that foreign matter invades state change.

In addition, being also configured to adjustment section 54 in the yarn clearer 15 of present embodiment in yarn 10 and not existing in inspection Survey in the state of region 36, and in the case that the adjustment as defined in detected value is continuous judge time disengaging normal range (NR), again into Row adjustment processing.

In this case, it can prevent from for example causing to carry out at unnecessary adjustment by noise that detected value is showed The case where reason.

In addition, the yarn clearer 15 of present embodiment is present in the foreign matter of detection zone 36 and has and be configured to wrap to remove Foreign substance removing apparatus containing first discharge port 151, the second outlet 152 and compressed air solenoid valve 48.At foreign matter reply Processing of the foreign matter reply processing that reason portion 59 carries out comprising making above-mentioned foreign substance removing apparatus movement.

Thereby, it is possible to remove the foreign matter of detection zone 36, to form the state for being suitable for adjustment processing etc..

In addition, foreign substance removing apparatus is and blowing air to detection zone 36 in the yarn clearer 15 of present embodiment Remove foreign matter.

Thereby, it is possible to remove the foreign matter for being present in detection zone 36 by simple structure.

In addition, should be wrapped to the foreign matter reply processing that processing unit 59 carries out in the yarn clearer 15 of present embodiment in foreign matter Containing the processing for making adjustment section 54 be adjusted processing again.

It is adjusted processing, again as a result, so as to effectively exclude influence of the foreign matter relative to detected value.

In addition, the yarn clearer 15 of present embodiment have determine yarn 10 whether there is in detection zone 36 yarn whether there is or not Determination unit 56.Foreign matter should even if comprising yarn, whether there is or not determination units 56 to be determined as yarn to the foreign matter reply processing that processing unit 59 carries out Line 10 is present in detection zone 36, the processing also acted in such a way that yarn 10 is not present in detection zone 36.

That is, in the case where foreign matter reply processing unit 59 is judged as foreign matter intrusion or is detached from, in yarn clearer 15 because of foreign matter Influence and can not accurately evaluate the state of yarn 10, therefore be not suitable for starting to wind in Yarn winding apparatus.Therefore, at this In the case of, by make yarn clearer 15 acted when not placing yarn 10 be reliably prevented from after start to wind.

In addition, whether there is or not determination units 56 to determine that yarn 10 whether there is in inspection for yarn in the yarn clearer 15 of present embodiment Survey the yarn path in region 36.

Yarn clearer 15 can reliably detect yarn 10 and whether there is in yarn path as a result,.In addition, at foreign matter reply In the case that reason portion 59 is judged as foreign matter intrusion or is detached from, yarn clearer 15 can be made when yarn 10 does not exist in yarn path Movement.

But it is also possible to should include the place for exporting foreign matter signal to the foreign matter reply processing that processing unit 59 carries out in foreign matter The winding that reason, output prevent the winding of the yarn 10 based on winder 18 from starting prevents the processing of signal and output from making to connect yarn Device connect in the processing for connecing yarn signal of yarn at least any one.

Thereby, it is possible to carry out various foreign matter reply processing.

In addition, the yarn clearer 15 of present embodiment has display lamp 46 and display 47.Moreover, display lamp 46 and aobvious Show that device 47 judges that the time is detached from foreign matter and sentences in the state that yarn 10 does not exist in detection zone 36, and in the continuous foreign matter of detected value In the case where disconnected range, reported.

The operator for operating Yarn winding apparatus (yarn winding unit 1) as a result, can be by display lamp 46 and display Device 47 grasps intrusion, disengaging of the foreign matter relative to detection zone 36.In addition, operator can manually stop yarn by notification The winding of line up- coiler.

In addition, the display 47 reported to operator is configured in the yarn clearer 15 of present embodiment Show at least what one display device in text, symbol and figure.

In addition, the display lamp 46 reported to operator is configured in the yarn clearer 15 of present embodiment The lamp lighted.

It can also be reported in simple structure to operator as a result,.In addition, can be reported under the illuminating state of lamp Know situation related with foreign matter, even if therefore operator from televiewing also be easy confirmation foreign matter intrusion/disengaging.

In addition, foreign matter copes with processing unit 59 and does not exist in detection zone in yarn 10 in the yarn clearer 15 of present embodiment In the state of domain 36, as shown in fig. 7, being more than the upper limit value of foreign matter determination range and from the foreign matter determination range in above-mentioned detected value In the case that the state of disengaging continues the stipulated time (specifically, judging the time for foreign matter), it is judged as that foreign matter has invaded detection Region 36.In addition, foreign matter copes with processing unit 59 in the state that yarn does not exist in detection zone 36, as shown in Figure 10, upper It states lower limit value of the detected value more than foreign matter determination range and the state being detached from from the foreign matter determination range continues the stipulated time (specifically For, foreign matter judges the time) in the case where, it is judged as that foreign matter is detached from from detection zone 36.

Foreign matter reply processing unit 59 can distinctively judge intrusion and disengaging of the foreign matter relative to detection zone 36 as a result,.

In addition, in the yarn clearer 15 of present embodiment, foreign matter determination range is using a reference value as past detected value On the basis of relatively determine.Moreover, foreign matter cope with processing unit 59 detected value be foreign matter determination range lower limit value more than and on In limit value situation below, in the judgement of next time, the new above-mentioned foreign matter that the detected value is determined as to said reference value is used Determination range.

Foreign matter reply processing unit 59 can rest in the state of foreign matter intrusion detection zone 36 as a result, with higher precision is It is no to there is variation.

But foreign matter determination range can also be determined as being fixed as shown in the example of Figure 12.

In addition, the yarn clearer 15 of present embodiment have determine yarn 10 whether there is in detection zone 36 yarn whether there is or not Determination unit 56.Yarn whether there is or not determination unit 56 detected value be defined yarn whether there is or not more than decision threshold in the case where, be judged as Yarn 10 is present in detection zone 36.Yarn is set as the value being detached from from foreign matter determination range whether there is or not decision threshold.

Yarn clearer 15 can grasp the foreign matters such as Soft flocks with the presence of yarn 10 in which distinguish as a result,.

More than, though the preferred embodiments of the present invention is illustrated, above-mentioned structural example such as can be as following It changes like that.

It can also be judged as the case where foreign matter invades detection zone 36 and be judged as what foreign matter was detached from from detection zone 36 In the case of, keep foreign matter different to the foreign matter reply processing that processing unit 59 carries out.For example, in the case where allotrylic Fig. 7, In order to remove foreign matter, and air is sprayed from first discharge port 151 and the second outlet 152, on the other hand, is detached from foreign matter It, can be without the injection of above-mentioned air in the case where Figure 10.

Structure for blowing from air to detection zone 36 is not limited to above-mentioned structure.For example, it is also possible to omit first Any of outlet 151 and the second outlet 152.Alternatively, it is also possible to the ejiction opening of air is not formed in shell 37, And air nozzle is formed in the front end for being set to external piping appropriate, and spray sky from the air nozzle relative to recess portion 38 Gas.

In addition, also foreign matter can be removed without using air, the insertion of thinner brush is formed in for example, it is also possible to have The recess portion 38 of the shell 37 of yarn clearer 15 is come the foreign substance removing apparatus that is cleaned.

Alternatively, it is also possible to be configured to omit the structure for removing foreign matter, and promote to grasp using display lamp 46, display 47 Foreign matter is removed from recess portion 38 with making personnel's manual working.It can also be not provided with display 47.

In the above-described embodiment, it is formed and is irradiated using receiving from light-projecting portion 41 towards yarn 10, and passed through yarn 10 Light that is, through light acceptance part 42, to judge intrusion/disengaging structure of the foreign matter relative to detection zone 36.However, It can also be formed and be irradiated using receiving from light-projecting portion 41 towards yarn 10 and in the light reflected of yarn 10 that is, the light of reflected light Portion, to judge intrusion/disengaging structure of foreign matter.

In the above-described embodiment, it forms yarn clearer 15 and has cutter 16, so as to the case where detecting yarn defect The structure of lower cutting continuous strand 10.It may, however, also be not having the yarn monitoring device of cutter 16.That is, yarn of the invention Monitoring arrangement is also possible to only monitor the device of the state of yarn.

In the above-described embodiment, reversion processing is carried out by being configured at the amplifier 43 of the back segment of acceptance part 42, therefore The light income of acceptance part 42 is bigger, and the output voltage of amplifier 43 is smaller.However, it is also possible to without using carrying out at above-mentioned reversion The amplifier of reason.In this case, therefore the longitudinal axis of chart shown in Fig. 6~Figure 10, Figure 12 with foreign matter up and down on the contrary, invade Enter/be detached from, in the related judgement of the presence or absence of normal range (NR) and yarn, the size relation of detected value inverts.

Yarn winding apparatus is not limited to spinning machine, automatic bobbin winder, or the Yarn winding apparatus of other structures.
