Description
Technical field
The present invention relates to be used for the apparatus and method that the exact measurement automatic winder is wound up into the length of yarn on the yarn tube.The present invention's reference yarn in this article is wound up on the taper pipe and forms yarn cone and describe, yarn cone is along with the live roll with straight drum moves together, but should know that the present invention also is applicable to the cylindrical shape yarn tube that formation is straight, described straight cylindrical shape yarn tube rotatablely moves on tapered roller.
Background technology
Bobbin-winding machine generally comprises a series of doff head or winder units of arranging along the front portion of machine, and be equipped with and be used for public actuating device that they are managed, these doff heads or winder unit are all separate, and therefore the yarn tube that is forming can have different progresses in their winding process.Referring to the scheme of Fig. 1, Fig. 1 illustrates the collection part of the yarn of coiling simply, and yarn tube 10 is by 11 clampings of creel arm, and described creel arm 11 has two dead points 12,13, and described two dead points 12,13 engage with taper pipe 14 at the place, bottom of yarn tube.The yarn cone 10 that is forming leans against on the live roll or collection cylinder 16 that is driven by motor M.Above-mentioned collection cylinder is equipped with the guide groove 17 that traverses, and described guide groove 17 usefulness of traversing axially seesaw yarn 18 is distributed on the surface of yarn tube 10, and swing roller transmits the necessary torque of reeling.The quantity that is positioned at the spiral that traverses on the driving drum 16 of yarn tube according to Yarn count with yarn tube density to be obtained and different; The general revolution of driving drum has 1.5-2-2.5-3 spiral.The pitch of spiral can be constant or variable.
Little by little increase size and weight at the yarn tube 10 that forms.Yarn tube having a significant impact on its collection cylinder 16 against the density of pressure to yarn tube self.In Fig. 1, yarn tube 10 is shown near its final size.
The length of yarn that is wound up on each yarn tube has an actual value, and described actual value has remarkable change between each winder unit that constitutes bobbin-winding machine.This depends primarily on the surface of yarn tube 10 and drives slippage between its surface of roller 16.Many reasons that cause slippage are arranged.At first, the geometric configuration reason is arranged, because lean against the tapering difference of the yarn tube 10 on straight transmission or the collection cylinder 16.The yarn tube lean against on its cylinder against the single shaft of line in coordinate, one " neutrality " point is arranged, at described " neutrality " some place, the surface of yarn tube has the linearity identical with cylinder surface (or tangential) speed.Against other some place of line slippage is arranged at the yarn tube: with less or relevant than major diameter, towards the tip direction, tangential velocity is lower, and towards bottom direction, tangential velocity is higher.Therefore the speed of returning of yarn have pulsation trend.At the whole coiling of yarn tube in the cycle, the axial coordinate of " neutrality " point is not changeless, above-mentioned axial coordinate can change with controlled mode and non-mode, and above-mentioned controlled mode is used to adjust the yarn tube and acts on the speed in the displacement to axial between creel arm and the driving drum.
Because the yarn tube is in the fluctuation of flattening phenomenon on the cylinder or because the parallelism defective between cylinder and the yarn tube, and the location defect between structure defective or the each several part, it is unfavorable perhaps to keep in repair, so even cylindrical shape yarn tube also has slippage, although not too remarkable.Because temperature or moisture fluctuation, yarn waxdip, because the fluctuation of the dead point bearing slip that dirt or lubrication deficiencies cause, the fluctuation that all may produce friction coefficient between the different yarn tube winder units.All of these factors taken together all causes the slippage between the different winder units, and this causes the difference of length between the produced simultaneously yarn tube, and described difference can reach 2-3%.
In the use subsequently of these yarn tubes, for example in weaving, different yarn tubes is used for the parallel yarn feeding of uniform machinery simultaneously, when the yarn tube that will at first use up uses up, all yarn tubes must unload, and replace with new yarn tube: in industrial practical application, the residual yarn that is wound up on other unexhausted yarn tube has all been wasted.Especially when working with high-quality yarn, no matter be that residual yarn is reclaimed or abandons, these unexhausted yarns all bring sizable cost burden.
The average slip that takes place on bobbin-winding machine is in 1.5% magnitude.In practical application at present, with the average overall correction of determined theoretical length, promptly the correction factor K that adopts at present introduces in the control unit of machine, and above-mentioned correction factor K will compensate the average slip of yarn tube.When the aviation value of yarn tube reaches desirable length, just obtain correction effect, yet the yarn tube that some is arranged is because the result that slippage disperses, have than actual length ± the littler or bigger length of aviation value of 2% gaussian shaped profile.
In known technology, when every batch operation begins, following definite correction factor K.On the control unit of machine, set the final lengths MF that wishes to get.Start the operation winder unit of some: it is preferred starting entire machine.Originally supposition, each yarn tube all are to be spurred by its cylinder under the situation of slippage not having.To each winder unit N
cAll measure the revolution of the cylinder 16 that is started,, then each of cylinder is transferred the length M of the yarn of coiling if the diameter of cylinder is known
cJust known.In each yarn tube winder unit, as product N
cM
cValue when equaling MF, the yarn tube is reeled and is stopped.When the yarn tube is finished, they are weighed or unwinding and measurement, effective final lengths value is compared with the theoretical value MF that is set up.Their ratio is corresponding to correction factor K, and described correction factor K will be incorporated in the control unit of machine, so that revise the MF of yarn tube subsequently.If the theoretical value MF that is set up for example is each yarn tube 1kg yarn, and the actual mean value that records on sample yarn tube is 0.984kg, then correction factor K equals 1/0.984.
Then, use the revised final theoretical length data M F of the correction factor K that is found, the operation of whole bobbin-winding machine is set by each yarn tube is introduced.Production afterwards, correction factor are sample control formulas, can and rebulid correction factor in the control unit adjusted.Each different operation is disclosed and classification correction factor K, for possible re-using.
This length detection method is not considered the following fact, and promptly spiral winding becomes to have the axial length component to yarn because it is distributed in the cross motion on the yarn tube.
Recently, for example in U.S. Pat 5652509, the length that some alternative systems are used for determining according to the speed that detects the coiling yarn yarn tube has been proposed.According to this prior art, system is based on the accurate and less Yarn senser that comprises two yarn properties (for example figure warp thread picture) reader, and described reader is arranged on the distance L place.If yarn has frequent identification and significant irregularity, then space/the time relationship between the image that is shown in order by two readers can be determined the conversion rates of yarn at any time.
Not only as when having pulsating speed under the situation of yarn cone, and when yarn rule or compact, i.e. when its basic irregularity was covered in its twisting, these systems were all having any problem aspect preparation and the work.If distance at interval in the L yarn might rotate around himself, have further measurement to disperse between then from the winder unit to the winder unit.Therefore, such sensor is insensitive to the slippage between yarn tube and the cylinder, and other relate to the difficulty of calibration at short notice and suitable computation ability.

f
The discrete measurement of each of the length of reeling can equal time gap at interval simply, for example, implements one-shot measurement by per 2 seconds kinds, then the length that records is added and.These are not necessarily mutually the same at interval.
According to the preferred embodiments of the present invention, time reference is not adopted in each discrete measurement at interval, but is reference with the revolution that increases progressively of head roll when the yarn tube begins, for example cylinder each hundred change.Like this, the branch length that at every turn records has just eliminated because the interruption of yarn and being connected subsequently, for the coiling adjustment of avoiding the entanglement on the yarn tube or owing to the influence of caused swing circles such as cycle under variable bit rate of any former thereby temporary transient motion of causing.In addition, the advantage of simplification being arranged is that first addend of formula (g) is the fixterm that needn't at every turn determine.
According to the preferred embodiments of the present invention, the measurement of the true diameter of yarn tube be with rang sensor 20 for example the reflector laser sensor implement in fixing geometric position, above-mentioned rang sensor 20 integral type as shown in Figure 2 is assembled on the creel arm 11, and it is positioned to be used to measure the surface of yarn tube and the distance between the projector, this measurement preferably according to the axes intersect of yarn tube 21 and perpendicular and axial coordinate value be that the straight line 22 of a is measured.Like this, because the geometric configuration of arm is fixed and arm moves along with ever-increasing yarn tube is whole, so the measurement that reduces gradually apart from the distance of yarn tube also just provides the measurement to the radius of ever-increasing yarn tube.The distortion on yarn tube surface does not influence the measurement of diameter in cylinder upper support line, because measurement point is positioned at suitably apart from the suitable distance of above-mentioned line, as shown in Figure 2.Illustrate in the drawings in the size of starting stage that the yarn tube is in its formation.
Under the situation of yarn cone, the decision of the axial location of sensor 20 realizes the axial coordinate of diameter measurement, and influences the observed reading of the φ that is obtained in this coordinate.In case the tapering of above-mentioned axial coordinate and yarn tube is known, then readily appreciate that the diameter of yarn tube in each axial coordinate.Referring to the scheme drawing of Fig. 3, under certain progress of yarn tube, by measuring diameter phi at axial coordinate a place yarn tube

In case the geometric configuration of yarn tube is known, then according to linear law (linear law), if cylinder has the plug helix (helix cavity) with invariable pitch, if perhaps have variable-pitch, then measure the diameter that just can calculate the spiral of reeling with the corresponding yarn tube of a certain axial coordinate diameter at each axial coordinate place of yarn tube bus according to the above-mentioned spiral of weight law.
As described so far, comprise following parts according to the yarn length measurement device that is wound up on the yarn tube of the present invention:
-be used for the yarn tube head roll increase progressively revolution-meter 30;
-be used for the yarn tube increase progressively revolution-meter 31;
Above-mentioned revolution-meter can be made with different technology.For example, revolution-meter can be made for rotating part to be become single-piece disk-for example and becomes integral body with the fixing dish 30 (keyeddisk) of key, the described dish of fixing with key 30 is inserted in Fig. 1 on the axis of head roll 16, or be inserted on the bearing of creel arm axle-above-mentioned disk has the outside face that has magnetic pole N-S, and the Hall effect probe is suitably located to show passing through of above-mentioned rotary pole.Each sensor just produces electric pulse by N (perhaps opposite S) utmost point dilation, and described electric pulse is sent to control unit with circuit 33.Because the number of magnetic poles that is arranged on the magnetic plate circumference is known, so can determine the revolution implemented by the count pulse number.If (rule and fitfull) duplicate measurements down at known interval then can be determined the speed of rotation of disk like this, so can determine the speed of rotation of cylinder or yarn tube.Possible alternative plan obtains in the following manner, promptly, can be applied to by the gear integral body that ferromagnetic material is made on the described rotating part and obtain with the control of induction type probe, perhaps the band N hole by being covered fork (blockage fork) (projector+receptor) control by optics or the wheel of tooth obtain or obtain by the reflecting disc of controlling with optical reflection sensor that has opaque " otch " on circumference;
The measurer 20 of the diameter of-yarn tube 10, described measurer 20 preferably is arranged on the creel arm securely.It can be made with various technologies.In order directly to measure diameter, can use reflection laser or so-called " flight time " laser, above-mentioned reflection laser is by the distance between triangulation technique calculating sensor and the object, and above-mentioned " flight time " laser is measured the time shifting between light of being launched and the light that is reflected: distance is big more, and then displacement/delay will be big more.Alternatively, when the geometric configuration of creel arm is known, detects described arm and obtain yarn tube diameter with respect to the geometric position energy measurement of head roll.Above-mentioned detection can for example use angle potentiometer (angular potentionmeter) to implement, the measurement that described angle potentiometer provides the creel arm to rise with respect to head roll: when the geometric configuration of assembly is known, can determine the diameter of yarn tube.Similarly, utilize induction or magnetic or optical pickocff to measure and become the single-piece point with respect to the distance that becomes single-piece point with drum assembly, can obtain the diameter of the yarn tube in formation with the creel arm.
Form the reflector laser sensor of one of them preferred embodiment of the present invention, can be easy to for example accurately be assemblied on the creel arm 11, thereby can drop on these type sensors and accurately measure in the desired dimension limit of yarn tube diameter by means of location template (template).
Compare with the yarn tube length degree measuring system of known technology, have sizable advantage according to method of measurement of the present invention and device, wherein following advantage is worth mentioning.Measurement is insensitive to slippage, because velocity measurement directly implements on the yarn tube, and measures also insensitive to the slippage fluctuation and the environmental factor of bearing.Measure also higher or insensitive to the yarn tube, because the measurement of yarn tube diameter can be implemented not flattened in the zone that influences by the yarn tube than lower density.The type of reading and yarn and number are irrelevant, and above-mentioned yarn can be single thread, twist yarn, regular or irregular, smooth or hair shape.
Length calculation is simple, does not need high computing power or high processing speed.The application of apparatus of the present invention does not hinder the yarn running, and is in the protected position that prevents accidental impact or contact.
