Description
Technical field
The present invention relates to a kind of method of on the actuation unit of rotor spinner, carrying out the single thread repiece, wherein, at first on the buoyance lift bobbin, detect the termination of yarn with hand, go out to carry out the length of the required yarn of described spinning-in process with hand measurement, after forming the termination of yarn, the termination of the yarn that bears is imported in the carrier pipe of spinning rotor.
The invention still further relates to a kind of device that is used on free-end spinning machine, implementing described method, described each actuation unit comprises that has a spinning apparatus of feeding strip device, a spinning rotor (spinning rotor), and yarn carrier pipe, at this above yarn carrier pipe, transport at described yarn a draw-off mechanism is housed on the passage, this mechanism comprises a pulling roll, and pressure roll that is installed on the swing depression bar, a yarn distribution mechanism and a Yarn winding apparatus structure, a bobbin is housed on the arm of this winding mechanism, also comprises a control device that is connected with described hello strip device.
Background technology
The spinning apparatus of rotor spinner comprises a fabric fibre bar feeding unit, be a filamentization (fiber singling-out) device subsequently, the fiber of single fiberization is drawn the inner space of this device and importing spinning rotor by negative pressure, and here collect on the feeder, and because the rotation of spinning rotor is converted into fibre bundle.By an efferent duct yarn in the production process is drawn described spinning rotor, carry out tractive, and be wound on the bobbin by pulling roll.By the existence of the yarn of a sensing device detection between described efferent duct and coiler device, when yarn breakage, send a signal by this checkout gear, stop the described strip device of feeding at least with indication.
Be called as the yarn repiece spinning process restart may further comprise the steps: along in the opposite direction described yarn end being imported the outlet of this spinning apparatus with the side of the outlet of yarn being sent into spinning apparatus, this yarn end is rested on the feeder of described rotary spinning rotor, before this, recovered the conveying of fiber in this feeder already, and on the feeder of spinning rotor, formed fibre bundle already single fiberization.After being connected to described yarn end on the described fibre bundle, having recovered traction action, and produced yarn by described fibre bundle to this yarn.
Described repiece process can adopt for this reason and one of well-known device of producing by manual or finish automatically.
When after yarn breakage, carrying out manual repiece, the operator at first tilts described bobbin, it is broken away from and the contacting of its live-roller, detect the yarn end on the described bobbin, the length of yarn that debatching needs, then this yarn end is imported the outlet of described spinning apparatus, described yarn end is sucked described outlet by the negative pressure that is present in the described spinning rotor.After described yarn end was imported the outlet of described spinning apparatus, the operator tilted to its operating position with the bobbin in the described coiler device, and at this moment, this bobbin contacts with described live-roller.Between this moving period, the operator has recovered the fiber of single fiberization is fed described spinning rotor.
In case described yarn end arrives the feeder of described spinning rotor, the fiber of described fibre bundle begins to combine with it, the bobbin that contact with its live-roller at present begins to rotate, and the yarn of new generation begins from described spinning rotor tractive and is wound up on the described bobbin in process of production.The operator can not influence the time interval that the fibre bundle of described regeneration is connected with described yarn end.In operation subsequently, the operator puts into described yarn between each pulling roll of draw rate during the decision spinning.
Described manual repiece can successfully be applied on the rotor spinner, this spinning machine is in process of production with very low yarn draw rate work, with regard to its output that improves this spinning machine, this all is disadvantageous for the producer of this rotor spinner and user.With after its live-roller contacts, need a period of time to make it accelerate to the peripheral speed that is equivalent to the yarn draw rate at interval at described bobbin.The described time interval increases along with the increase of draw rate and tube quality.Because described bobbin is started working, when described yarn end arrives the feeder of described spinning rotor, the transient motion speed of this yarn is lower than this yarn work draw rate in process of production, therefore, (abutment of described yarn end and described fibre bundle) adds the fiber that twisting count is different from the some that adds twisting count of adjacent yarn part and is deposited in its joint.Described joint can form the thread segment of the chap that can with the naked eye perceive in further processing, the part of this chap can cause serious aesthetic drawback, and this defective does not exist only on the described yarn, but also is present on the product of being produced by this yarn.
In view of above defective, manual repiece method is progressively replaced by automatic repiece method, automatically the repiece method mainly develops along both direction, promptly by the mechanism of actuation unit or the device that adds by employing, this attachment device is applicable to along described spinning machine and moves and rest on selected any actuation unit place.
The repiece automation that mechanism by described actuation unit realizes, for example be proved too complexity and cost prohibitive disclosed in the Czech patents CZ200910, because it requires to stop the conveying of yarn after yarn breakage, making the termination of yarn still rest on described carrier pipe the inside, is impossible obtain high yarn draw rate like this.
The automation repiece of being undertaken by an attachment device is the method for carrying out automation yarn repiece that adopts on rotor spinner the most at large at present.For example, as disclosed in the Czech patents application CZ2694-95, after yarn ruptured on rotor spinner, first step was, at first by the yarn end on the detection of negative pressure described buoyance lift bobbin, and it is sucked one detects in the shower nozzle.Second step, the yarn repiece length that debatching needs from the described bobbin, described yarn moved to described spinning apparatus and make it to be subjected to the effect of described attachment device, pass through all the additional actuation units except described yarn distribution mechanism so that guarantee movement locus.Formed the repiece of described yarn at the end of the length of yarn that is measured, this repiece imports in the described spinning rotor by negative pressure is local in a first step.Then, described yarn is subjected to the effect of the arrangement for deflecting of the attachment device between the draw-off mechanism of described spinning apparatus and described spinning machine additional manipulation unit, when above-mentioned effect finishes, the yarn end that is generated arrives on the feeder of described spinning rotor, and here be created on this feeder in the fiber of fibre bundle engage continuously.Then, this yarn is subjected to the effect of actuation unit, so that tractive, detection and this yarn of reeling, then this yarn is transferred to from described attachment device on the distribution apparatus of additional manipulation unit of described spinning machine again.Can repeat to obtain the joint of equal in quality and size like this.Even also can obtain high-quality, small-sized joint during with the work of high draw rate at rotor spinner.
The raising that the defective of above-mentioned repiece method has caused the technical quality to the operator to require, so that can correctly regulate described attachment device, therefore, although can enough this repiece systems produce quality yarns with high productivity ratio by described rotor spinner, but this point is difficult to accomplish, particularly is difficult to be realized by the lower labour of technical merit.
The principle of the invention
Alleviated or eliminated fully the above-mentioned defective of prior art already by method of the present invention.The principle of this method is, before repiece, described yarn imported the passage that transports of the actuation unit that is arranged in rotor spinner, and by a draw-off mechanism, promptly between the pressure roll by a pulling roll and relative this pulling roll inclination, by the described distribution mechanism outside time, at least one arrangement for deflecting of actuation unit by described spinning machine makes this yarn depart from it and transports passage, unclamp described arrangement for deflecting then, and therefore make the repiece end of described yarn arrive on the feeder of described spinning rotor, on this feeder, formed fibre bundle before this, begin then this yarn end is bonded on the described fibre bundle, on the feeder of the described spinning rotor of the terminal arrival of the repiece of described yarn and after through the preset time interval, the draw-off mechanism of the actuation unit of described spinning machine begins the described yarn of tractive, and the winding mechanism of the actuation unit of described spinning machine begins the yarn of reeling.
This method can improve the quality of described joint, and therefore improves the quality of yarn of being produced, and quality of yarn mainly is the influence that is subjected to the quality of described joint.This can also improve described repiece efficiency of operation and reliability, meanwhile, has also reduced operator's technical merit and the requirement of working time.
Preferably, before the yarn repiece, make described yarn depart from the outlet opening that it transports passage and passes through described carrier pipe in described distribution mechanism front, equal the distance between the feeder of described repiece yarn end and described spinning rotor at the offset distance on the described carrier pipe outlet opening, after described repiece process finishes, eliminate the deflecting action above the outlet opening of described carrier pipe.
Like this, the reliability of described repiece still is improved, because can not be subjected to the obstruction of other device when sucking described yarn in the described rotor, and the distance between the outlet opening of described inflexion point and described carrier pipe is reduced to minimum.
Can further improve said method by eliminating the yarn deflection of carrying out previously in described distribution mechanism, described elimination process only be get around at the yarn tractive that is undertaken by draw-off mechanism with by the reel for yarn that winding mechanism carries out the beginning after enforcement, thereby described yarn is transferred to described distribution mechanism and prevent the danger that it is broken by described distribution mechanism in the repiece process.
In a kind of economical modification of the inventive method, described yarn only departs from described distribution apparatus, and, described deflection elimination process realizes by two steps, first step wherein is to carry out before repiece, and the yarn end of repiece is sent back on the feeder of spinning rotor, and second step is carried out at the beginning tractive with after reeling, discharge described yarn, so that distribute by described distribution mechanism.
Advantageously, detect the existence of yarn between the outlet of described carrier pipe and estimate its quality, and when lacking yarn or detecting bad quality, stop described actuation unit.
The principle that is used for the device of enforcement said method on a free-end spinning machine is, the arm of described coiler device is connected with a control electromagnet with the depression bar of described draw-off mechanism, this electromagnet is connected with a control device, described control device also is connected with a yarn deflection piece, so that departing from it, described yarn transports passage, described yarn before the described repiece process and during be arranged in it and transport passage, this transports passage in the pulling roll of described draw-off mechanism with between the pressure roll that this pulling roll tilts relatively.
If can make described deflection piece will be favourable as a deflection piece that is positioned at described carrier pipe outlet opening top.
In another embodiment, described deflection piece is as described distribution deflection piece.
Consider from the reliability angle of described repiece process, it will be favourable contacting with described yarn simultaneously if described deflection piece is suitable for picking up two privileged sites, more properly say, a position is the position that maximum deflection was arranged before repiece, and another is the position that has during repiece than primary deflector.
In order to improve described quality of yarn, utilize a yarn existence and mass sensor to measure the quality and the size of described joint, and this sensor is connected with described control device, so that when the yarn of bad quality occurring or when described joint is between the outlet opening of described carrier pipe and described winding mechanism, stop described actuation unit.By being installed in, described sensor can detect the optimum quality of described yarn in process of production on the described position.
It is favourable for described control device a switch being installed, and this switch is installed in the scope that the operator can get on the actuation unit of described spinning machine.

Deflection yarn distribution electromagnet 101 moves to the deflection distribution part 10 of yarn 32 on its inflection point.
When on an actuation unit yarn breakage taking place, the operator clears up spinning rotor 14, checks the yarn end on the bobbin 92, and begins to make yarn 32 unwindings.At unspooling operation, the operator imports by buoyance lift bobbin 92 yarn 32 and detects the sensor 7 that yarn 32 exists by deflection yarn distribution part 10, yarn is inserted described draw-off mechanism, promptly insert between the pulling roll 41 of pressure roll 43 and these pressure roll 43 inclinations relatively, yarn is imported the sensor 6 that is used for detecting yarn 32 existence and quality, yarn is flowed to measurement mechanism M or cutter sweep, yarn is prescinded the needed length of repiece, thereby the yarn 32 in unwinding from bobbin 92 forms the termination that is generated, this termination is inserted in the outlet opening of yarn carrier pipe 15 by the operator then, enter after this outlet opening, owing to existing negative pressure in the spinning rotor 14 is attracted it.
In this stage, the sensor 7 of yarn 32 existence drawn, is used to detect by the guiding process of deflection yarn distribution part by yarn 32 from bobbin 92, pass through draw-off mechanism 4, promptly pass through from rotation pulling roll 41 with between the pressure roll 43 that this roller tilts relatively, through being used to detect the quality of yarn 32 and the sensor 6 of existence, and enter carrier pipe 15 towards spinning rotor 14 motions, but, can not arrive feeder 141 as far as spinning rotor 14.The feeding unit 11 of strip 3 is shut down, and spinning rotor 14 rotates, and additional actuation unit performs the preparation of carrying out the repiece operation.At this moment, yarn 32 be arranged in its normal spinning transport passage different transport passage, its difference only is to hold it in by deflection yarn distribution part 10 outside of yarn distribution mechanism 8.
The repiece process preferably by the operator only switch S by the control device A that closes start, described control device engages clutch 111, the feeding roller of feeding unit 11 is rotated, thereby begin that strip 3 is transported to the single fiber makeup and put 12, transport passage 13 by transhipment described fiber is put the importing spinning rotor 14 from this single fiber makeup, on this feeder 141, convert it into fibre bundle 31 at spinning rotor 14.Before generating described fibre bundle 31, this control device A starts deflection yarn distribution electromagnet 101, discharge the deflection yarn distribution part 10 of yarn 32 by this electromagnet, yarn 32 discharges from deflection distribution part 10, and the repiece end of yarn is inhaled in the spinning rotor 14, here it can arrive as far as feeder 141, and on this feeder, the repiece end of yarn engages with fibre bundle 31 in a known way to form yarn 32.At fibre bundle 31 with after yarn 32 is connected, by described control device start-up control electromagnet 5, this control electromagnet starts the first control tie-rod 51, so that rotate depression bar 44, make it get back to described pressure roll and described rotation pulling roll 41 position contacting, clamp yarn 32 and from spinning rotor 14, it is carried out tractive.Meanwhile, control electromagnet 5 makes the arm 94 of winding mechanism 9 begin to tilt to such position by second control tie-rod 52: wherein said bobbin 92 is positioned on the driving drum 91, and yarn 32 begins to be wound on the bobbin 92.When draw-off mechanism 4 was started working, control device A started the quality of yarn 32 and has sensor 6 and the sensor 7 of yarn 32 existence, perhaps begins to handle the signal that is sent by described sensor 6,7.Therefore, also to measure the repiece of yarn 32 terminal with the abutment of fibre bundle 31, the i.e. quality of so-called " joint ", subsequently, the yarn qualities in the mensuration production process.The existence of each the sensor yarn 32 in two sensors 6,7.
In fact can not influence the quality of described joint by the manual repiece process of finishing of operator because described repiece operation preferably actuation unit by spinning machine carry out.Therefore, this machine can be by only possessing very low technical ability, untrained operator's management.
If before repiece, yarn 32 discharges from deflection yarn distribution part 10 fully, just exists the danger that yarn 32 is hooked by yarn distribution mechanism 8 before repiece finishes.In order to eliminate this danger, in another embodiment, deflection yarn distribution part 10 has a specific string-up position ZP, to guarantee that yarn 32 equals the distance between the feeder 141 of the terminal and spinning rotor 14 of the repiece of yarn 32 in carrier pipe 15 via the length difference of deflection yarn distribution part 10 by its inflection point VP and its string-up position ZP, as shown in Figure 2.Therefore, before repiece, deflection yarn distribution part 10 moves to string-up position ZP by inflection point VP, and thus, the repiece end of yarn 32 moves on the feeder 141 of spinning rotor 14, and here it begins to engage with fibre bundle 31.Have only after control device A has sent tractive, coiling and the detection instruction that recovers yarn 32, this control device A just can start deflection yarn distribution electromagnet 101 deflection yarn distribution part 10 is moved into place the off-position of transporting the passage outside in yarn 32.After discharging deflection yarn distribution part 10, yarn 32 is clamped by yarn distribution mechanism 8, so that cross winding is on bobbin 92.
In embodiment shown in Figure 3, its repiece process is similar, different is, the yarn 32 that keeps in order to carry out repiece is realized by starting deflection yarn distribution part 20, and described deflection yarn distribution part is the instruction startup of deflection yarn distribution electromagnet 201 according to control device A.
Deflection yarn distribution electromagnet 201 and deflection yarn distribution electromagnet 101 can be used such as other suitable known devices such as cylinder, stepper motors and replace.
