Description
Technical field
The present invention relates to the method for a kind of monitoring quality of yarn of longitudinal movement on the station of the textile machine of making cross winding bobbin; In said method; By means of device; With the diameter deviation of yarn and longitudinal length is estimated relevantly and the yarn of classifying in the yarn defect, this realizes through determined deviation and predetermined clearing threshold value (Reinigungsgrenze) are compared.
Background technology
EP 0 877 108 B1 disclose a kind of method of monitoring the quality of yarn of longitudinal movement.Making yarn or during the after-combustion yarn, detecting measurable characteristic of yarn, wherein, define yarn defect to be removed according to this method, confirm in view of the above which yarn defect must be eliminated and which need not be removed through the clearing threshold value that can set.Method according to EP 0 877 108 B1 stipulates that also the clearing threshold value can adapt to the situation of the variation on station or textile machine.Begin from predetermined clearing threshold value, recomputate and adjust this clearing threshold value according to the shearing frequency with hypothesis of reality.For example, reduce, then adjust the clearing threshold value, so that the yarn defect of previous tolerance also was eliminated if cause shearing frequency owing to yarn qualities is higher.This way has hindered the capacity rating of textile machine usually.
Summary of the invention
Therefore task of the present invention is to provide a kind of method, and it makes can keep the yarn qualities selected when capacity rating is best.
The present invention has stipulated the method for a kind of monitoring quality of yarn of longitudinal movement on the station of the textile machine of making cross winding bobbin; In said method, relevantly estimate yarn defect in said yarn with evaluating apparatus with the diameter deviation and the longitudinal length of said yarn by means of testing fixture, wherein; Compare with longitudinal length diameter deviation of estimating relatively and the clearing threshold value that is arranged in the system of axes with diameter deviation coordinate and yarn defect length coordinate determined; And removing is in those deviations on the said clearing threshold value, and said method is characterised in that, stipulates a width in said system of axes, for the position of said clearing threshold value; Said width limits through the lower limit and the upper limit; Wherein, the diameter fluctuation under said lower limit is not be evaluated as the yarn defect, and each the yarn defect on the said upper limit all is eliminated; And the each given yarn qualities of foundation on said station; Said clearing threshold value so changes within said width; Therefore that is, between said clearing threshold value and said lower limit and be retained in the predetermined yarn defect quantity per unit length flat fabric, that depend on quality that the quantity of the yarn defect in the yarn is no more than the per unit length yarn or is processed by this yarn.
The present invention's first invention suggestion; At first give location definition one width of the clearing threshold value in the system of axes; This width limits through the lower limit and the upper limit, and the diameter fluctuation under lower limit is not be evaluated as the yarn defect, and each the yarn defect on the upper limit all is eliminated; And under the situation of corresponding given yarn qualities on the station; The clearing threshold value so changes within said width,, between clearing threshold value and lower limit, also therefore is retained in the predetermined yarn defect quantity per unit length flat fabric, that depend on desirable minimum quality that the yarn defect quantity in the yarn is no more than the per unit length yarn or is processed by this yarn that is.Thereby, can under the situation of optimum productivity, guarantee minimum winding quality and build guality.Within the width of setting through the upper and lower bound of confirming according to selected yarn qualities, under the coiling condition or the situation about changing of creating conditions, on textile machine, adjust the clearing threshold value flexible automaticly.
Along with the minimizing of not removing yarn defect quantity, the clearing threshold value can move towards the direction of the upper limit like this; And along with the increase of not removing yarn defect quantity, the clearing threshold value can move towards the direction of lower limit.This mode mainly is from the consideration to following situation; Wherein, Under the situation that the clearing threshold value remains unchanged, with regard to certain section length of yarn or a perhaps area of a length of the flat fabric of just processing, compare with the situation of having used a period of time and then having had a corresponding worn spinning rotor by it; Under the situation of the new spinning equipment of application examples as new spinning rotor, the quantity of the yarn defect that is not eliminated in the yarn still less.Therefore, make those can be retained on the yarn based on the yarn defect that the setting of clearing threshold value can be eliminated originally through move the clearing threshold value towards the upper limit.Move the clearing threshold value like this and reduced yarn clearer shearing number of times, thereby improved capacity rating once more.Under reverse situation, when the spinning equipment wearing and tearing increased, the yarn defect quantity of reservation was also increasing, and therefore moves the clearing threshold value towards lower limit.Increased yarn clearer thus and sheared number of times, and can not run counter to quality criteria, said quality criteria is the permission quantity of not removing the yarn defect in yarn.
The clearing threshold value preferably can be moved in the part within a width.In this case, this for example moves and treats that along being preferably in the normal perpendicular to the upper limit or lower limit extension carries out within the moving area.Can in certain segment length scope, eliminate the yarn defect thus significantly or permit the yarn defect significantly and exist.
In addition, the clearing threshold value can within this width, be parallel to lower limit and/or the upper limit moves, and always keeps uniform distances along clearance curve with respect to the upper limit or lower limit thus, that is to say, has obtained the yarn cleaning characteristic (Renigungsprofil) that remains unchanged.
Alternatively, the clearing threshold value can be parallel to abscissa and moves.
Same clearing threshold value also can be parallel to ordinate and move.
Move under the situation of clearing threshold value in the part when needed, should be only this clearing threshold value be moved to a bit intersecting for the first time with the upper limit or lower limit of this clearing threshold value till.Can avoid the clearing threshold value to be positioned at regard to quality and capacity rating in this manner outside the tolerable width, is positioned at the scrubber that can cause outside the tolerable width occurring not expecting and shears number of times or can cause surpassing the quantity that the yarn that limits according to selected quality loop is not removed the yarn defect.
In addition,, can one group of clearing threshold curve be stored in the memory device, when the clearing threshold value changes according to the present invention, from this memory device, select and the different clearing threshold value of using before this of clearing threshold value according to alternative means.
Description of drawings
Embodiment below in conjunction with shown in the accompanying drawing further describes the present invention.
In the accompanying drawing:
Fig. 1 illustrates the scheme drawing of spinning position;
Fig. 2 to Fig. 5 is respectively at the various curves of the threshold value of clearing shown in the rectangular coordinate system.
The specific embodiment
Set forth according to the method for the invention below in conjunction with rotor spinner, this method also can be applied to other textile machine certainly, in these textile machines, is provided with testing fixture and/or control monitor unit for the quality of yarn of controlling longitudinal movement.
In the spinning position 1 of open-end spinning machine shown in Figure 1, yarn 19 is wound to cross winding bobbin 4 via unwinding yarn pipe 2 from spinning box 3.Yarn 19 through being used for the yarn clearer 5 of quality monitoring, passes through thread eye 9 subsequently between unwinding pipe 2 and cross winding bobbin 4, wherein, yarn clearer 5 comprises measuring head 6, shear 7 and treater 8.Head roll 10 drives cross winding bobbin 4 by means of frictional fit in winding process.Motor 11 makes head roll 10 carry out the required rotational motion of winding process.
Yarn clearer 5 is used for monitoring constantly at manufacturing process the quality of the yarn 19 that advances.Measure the diameter of the yarn 19 that advances for this reason by means of yarn clearer 5, and compare with the predetermined diameter value.For the quilt of measuring diameter (measuring thickness in other words) and yarn 19 measures the longitudinal length of diameter deviation, used known optical sensor arrangement and/or capacitive sensor means itself.The yarn clearer of for this reason using 5 comprises the measuring head 6 based on the one combination of optics and/or electric capacity work.For the take off data that processing and detecting arrives, yarn clearer 5 is connected with some other device by means of circuit 12, and other these devices are used to control, data storage, analysis and driving spinning position other element of rotor spinner in other words.If it is excessive or too small that yarn clearer 5 identifies the diameter of yarn 19, then detect the length of this yarn defect through control setup 13.If detect unallowed yarn defect, then suspend ribbon is delivered to the fibre-opening unit having in the spinning box 3, and remove this yarn defect according to the exemplary predetermined clearing threshold value 14 that illustrates of Fig. 2 to Fig. 5.
Fig. 2 is in the example plot of the clearing threshold value 14 that can be scheduled to shown in the rectangular coordinate system, and abscissa is represented the yarn defect length of yarn 19 in this system of axes, and ordinate is represented the diameter deviation of yarn 19.But but clearing threshold value 14 is extended between predetermined lower limit 15 and preset upper limit 16.The lower limit 15 representatives diameter fluctuation relevant with longitudinal length, wherein, the diameter deviation under lower limit 15 is not be evaluated as the yarn defect.On the contrary, each diameter deviation on the upper limit 16 all is eliminated as the yarn defect.
Between the lower limit 15 and the upper limit 16, form width 18; Within width 18; The curve of clearing threshold value 14 can be moved in the part at least; And without prejudice to predetermined quality criteria, this quality criteria be in per unit length yarn or the per unit length flat fabric processed by yarn subsequently, allow the yarn defect quantity that is not eliminated.According to the current actual spinning conditions at least one spinning position 1, move clearing threshold value 14 partly or fully.When causing necessary yarn clearer to shear the number of times minimizing owing to diameter fluctuation number of times (this diameter fluctuation is the diameter fluctuation between clearing threshold value 14 and lower limit 15) minimizing, clearing threshold value 14 moves towards the lower setting of sensitivity towards the direction of the upper limit 16.This situation for example is when improving the quality of the yarn of making through rotor spinning 19 owing to the spinning equipment of changing spinning position 1, and this moment, yarn defect quantity reduced.Under reverse situation, if the yarn defect quantity that remains surpasses the quantity that allows, then clearing threshold value 14 moves towards the direction of lower limit 15.Here, clearing threshold value 14 changes with the mode that does not exceed the lower limit 15 or the upper limit 16 within width 18.Guaranteed in this manner; Under the big as far as possible situation of the capacity rating of spinning position 1; The yarn 19 of manufacturing has desirable minimum quality, that is to say, the not removing yarn defect in the flat fabric that yarn is perhaps processed by it does not subsequently have a predetermined level is exceeded.
As shown in Figure 2, clearing threshold value 14 changes towards the direction of the lower limit 15 or the upper limit 16 with the mode perpendicular to clearing threshold value 14 curves, and this is through representing along moving of straight line 17.In the embodiment shown, straight line 17 is plotted as angular bisector, and this angular bisector extends perpendicular to these clearing threshold value 14 ground at the joining place of itself and clearing threshold value 14.Said moving can be parallel to lower limit 15 or the upper limit 16 ground realization (the clearing threshold value 14 after for example in Fig. 2, representing by a dotted line to move '), perhaps through realizing around the straight line 17 and joining rotation clearing threshold value 14 ground of clearing threshold value 14.
Fig. 3 illustrates a kind of variant; Wherein, only move the regional area of clearing threshold value 14, its implementation is that straight line 17 is arranged in the regional area that need move; So that only the regional area of clearing threshold value 14 is moved (be represented by dotted lines among the figure after moving clearing threshold value 14 ') along straight line 17; Wherein, perpendicular to this clearing threshold value 14, this moment, clearing threshold value 14 remainder did not move straight line 17 at the joining place of itself and clearing threshold value 14.
Fig. 4 and Fig. 5 illustrate clearing threshold value 14 respectively in another alternate embodiments that within the width 18 between the lower limit 15 and the upper limit 16, moves.
According to Fig. 4, clearing threshold value 14 is parallel to ordinate and moves, the clearing threshold value 14 after the dotted line among the figure is represented to move '.And according to Fig. 5, clearing threshold value 14 is parallel to abscissa and moves, the clearing threshold value 14 after the dotted line among the figure is represented to move '.In Fig. 4 and embodiment shown in Figure 5, only moving clearing threshold value 14 in the part also is feasible.The something in common that moves all modes of texturing of clearing threshold value 14 is, when a bit the intersecting with the lower limit 15 or the upper limit 16 of clearing threshold value 14, just can not proceed to move.The lower limit 15 or the upper limit 16 have only constituted threshold value with regard to waiting to make or treating with regard to capacity rating and the quality of yarn 19 of after-combustion.
