Description
Technical field
The present invention relates to the method for the station for operating the weaving loom producing cross winding bobbin, wherein said station is provided with for being wound around the doff device of described cross winding bobbin and the suction nozzle by independent direct motor drive, described suction nozzle is positioned at the end of a thread receiving position, for being received in doff the yarn of having no progeny and advancing on the surface of described cross winding bobbin, described position has preset distance from the opening of described suction nozzle to the surface of described cross winding bobbin.Described suction nozzle relies on its individual driver pivotable to leave the initial position that sensor detects, and after predetermined increment, stopping at described the end of a thread receiving position.In addition, the present invention relates to the station of the weaving loom producing cross winding bobbin, it is for implementing according to method of the present invention.
Background technology
The station producing the weaving loom of cross winding bobbin is public domain in for a long time, and in a large amount of patent documentations, there is details to describe, it comprises and is wound around the doff device of cross winding bobbin and the suction nozzle for being received in doff the yarn of advancing on the surface of cross winding bobbin of having no progeny, particularly with intersect wire coiling machine and be connected.
Such as in DE10150590A1, describe a kind of station, it comprises suction nozzle, suction nozzle can receive so-called upside yarn, on the upside of this, yarn is advanced after yarn breakage or after being cut off by yarn clearer on the surface of cross winding bobbin, and upside yarn is placed in the yarn splicing device of pneumatic mode operation by suction nozzle, then upside yarn is engaged to the downside yarn provided by so-called clamp in yarn splicing device.
Suction nozzle can move between Support Position, two ends, and exerted pressure by tension spring simultaneously and prop up the so-called bending disk bending disk bag, this bending disk bag is connected to again the center driver of relative stations.
By driving the relevant rotation of station actuator and bending disk bag that suction nozzle can be made to be switched to the end of a thread receiving position, in this position, the opening of suction nozzle is positioned in the region on the surface of the cross winding bobbin be installed in bobbin framework.
At described the end of a thread receiving position, suction nozzle supports against so-called suction nozzle backstop, relies on this backstop, can regulate and receive during the end of a thread from the opening of suction nozzle to the optimum distance between the surface of the cross winding bobbin rotated along unreeling direction.
In order to ensure the starting point (namely when little cross winding bobbin) in bobbin movement and this optimum distance can be ensured at the terminal of the bobbin movement of large cross winding bobbin, the lever system being connected to bobbin framework is relied on to carry out automatic tracing suction nozzle backstop, that is will according to the diameter of bobbin.
The mechanical type suction nozzle backstop of the automatic guide of the type has proved it is actv. in principle, but still has some shortcomings.
Such as, if there is problem at the reception period of yarn ends in these known devices, this need calibrate suction nozzle opening to cross winding bobbin surface between distance, then first need the adjustment of some relative efforts.
This means, on said device, each status requirement operating personal changing suction nozzle backstop carries out manpower intervention consuming time.
In practice, often delay the aligning again of suction nozzle backstop, because when receiving the end of a thread, error rate can increase, this significantly reduces the usefulness of relevant weaving loom.
With regard to cross-winding bobbin winder, prior art also comprises the suction nozzle driving station respectively with corresponding individual drive, and wherein stepper motor is often used as individual drive.
In EP0717001B1, such as describe a kind of station intersecting coil winder, wherein clamp, suction nozzle and yarn splicing device are all by independent direct motor drive.Actuator relevant is in this case connected on the station that controlled by electric apparatus, which ensure that the proper operation of equipment.
In EP0717001B1, do not comprise such details: such as at the reception period of the end of a thread, how to guarantee that the opening of suction nozzle is always positioned at and has predetermined optimum distance place with the surface of the cross winding bobbin rotated along unreeling direction.
A kind of method is described in DE102006026548A1, for operating the station of the weaving loom producing cross winding bobbin, wherein be pivoted into predetermined the end of a thread receiving position accurately by the suction nozzle of independent direct motor drive, after being received in yarn breakage or controlled yarn cut off after the yarn of having advanced on the surface of cross winding bobbin.
Therefore, make suction nozzle leave by pivotable the fixed position detected by sensor by its actuator and enter the end of a thread receiving position, this actuator performs the control step of predetermined quantity, on this end of a thread receiving position, between the opening of suction nozzle and the surface of cross winding bobbin, there is the optimum distance precisely limited.
Therefore, move the period adjustable number of steps being preferably designed for the suction nozzle actuator of stepper motor at bobbin, and will each change of the surface location of the cross winding bobbin determined by diameter increase be considered.
This means the respective diameters according to cross winding bobbin, the opening of suction nozzle is positioned at different the end of a thread receiving positions respectively.
The method described in DE102006026548A1 has been proved to be very effective in practice, like this, in the station using described method, relatively for a long time or during relatively a large amount of the end of a thread receives and attempt, it is very high that the end of a thread receives the successful quantity of attempting.
But, what shown is, the method even known to all has risk, namely, the end of a thread receives the successful quantity of attempting and declines along with the time, such as, this is because the opening of suction nozzle can change in the location of predetermined the end of a thread receiving position, this can not by operating personal identification or few identification.This means, once unsuccessfully cause the validity of relevant weaving loom to reduce due to trial increasing in the end of a thread receiving course, generally just can only identify subideal the end of a thread receiving position of the opening of suction nozzle in practice.
It is envisaged that except the distance of suction nozzle, acceptance rate reduces and also has other reasons, the such as fluctuation of suction pipe negative pressure, and bobbin structure, variable waxes, the yarn tension etc. of change.Therefore change in practice is also only the method for mistake by the decline suction nozzle position that causes of verification and measurement ratio.
Summary of the invention
Based on above-mentioned prior art, basic goal of the present invention is a kind of method of exploitation or the station for performing the method, can guarantee the end of a thread reception period at the yarn of having advanced on the surface of cross winding bobbin in a straightforward manner by the method, the opening being responsible for the suction nozzle receiving the end of a thread is always accurately positioned at predetermined the end of a thread receiving position.
Described object is realized by such method according to the present invention, the pivotable of namely calibrating suction nozzle moves, and makes to have no progeny in doff, first performs and connects yarn program, yarn is fixed in yarn tensioner by this, and relies on the cross winding bobbin along winding direction pressurization to carry out tensioning yarn.After this, its individual driver is relied on to leave suction nozzle pivotable by the reference position of zero position sensor definition and enter control position, in this control position, the yarn of the suction hose contact tensioning of suction nozzle, wherein relies on yarn tensile strength sensor to detect the position of suction hose on the yarn of tensioning.In addition, during suction nozzle pivotable, when suction nozzle pivotable is left reference position that sensor detects and is entered the control position of yarn of suction hose contact tensioning of suction nozzle, determine the quantity increment of process.Then, the quantity increment determined compares with the indicatrix quantity of the increment determined in the same fashion, and relatively sets up calibration variables based on this, can consider this calibration variables at the follow-up location of the suction nozzle being arranged in the end of a thread receiving position.
Especially possess such advantage according to method of the present invention, the reduction because of the yarn ends verification and measurement ratio caused by the mechanical misalignment between suction nozzle actuator and nozzle head can be avoided by described method.This means can during the end of a thread check processing of station, prevent nozzle openings from arriving the less desirable change of bobbin distance between the surface by this method.
By using according to method of the present invention, during calibration process, suction nozzle does not need to be applied to fixed datum, and this not only often has problems when stepper motor is used as actuating device but also because of the rdativery sensitive design of suction nozzle.
This means often there is such risk when suction nozzle being moved to fixed datum, namely may have unobservable mis-aligned in the region of nozzle structure or in the region of actuator, this mis-aligned has very adverse influence for alignment method.
In an advantageous embodiment, increment counter is relied on to determine the quantity of the increment of the suction nozzle process when suction nozzle is pivoted to the control position between the flank and the signal of yarn tensile strength sensor of zero position sensor.
In this way, the pivoting angle that suction nozzle arrival control position has to pass through can be determined quickly and accurately.
This means, if the quantity increment such as determined at the installed position of suction nozzle is different from predetermined value, then can directly calibrate.
Preferably, rely on its individual driver, the reference position detected from sensor to be positioned at the control position the yarn of tensioning to nozzle openings, and pivotable is for several times continuously for suction nozzle.
Enter the pivotable of its control position by repeating suction nozzle, can reliably prevent single slight error, this mistake has adverse effect for the result of a measurement that will consider.
In an advantageous embodiment, the calibration of the pivoting action of suction nozzle is automatically carried out in specific period, and wherein the type in cycle can have different selections.
Such as, the first selects to be that the pivotable that suction nozzle automatically calibrates suction nozzle moves after the end of a thread receives trial pre-determined number.
In another Advantageous variants, the pivotable of always calibrating suction nozzle with predetermined time interval moves.
Also possible that, once produce the cross winding bobbin of predetermined quantity, the calibration of the pivotable movement of suction nozzle will have been carried out.
Above-mentioned three embodiments have been proved to be very favorable in practice, and thus after predetermined quantity has been attempted in the end of a thread reception of suction nozzle, automatic calibration mainly considers the actual stress on suction nozzle, therefore seems the most favourable.
In another Advantageous variants, it is only calibrate when being necessary that the pivotable of suction nozzle moves.
This means, when the end of a thread acceptance rate reduces, first to perform calibration process according to the present invention to get rid of the following fact: the reason that the end of a thread verification and measurement ratio reduces is the mis-aligned of suction nozzle.
Only have when yarn verification and measurement ratio is unsatisfactory even after calibration, just need to check relative stations for every other possible cause, the fluctuation of such as negative pressure, bobbin structure, the variable yarn tension etc. of waxing, changing, the above-mentioned reason that also can become the end of a thread verification and measurement ratio and reduce.
Even if the pivotable only can calibrating suction nozzle in principle where necessary moves, but it is favourable for regularly carrying out calibrating, because reliably can prevent the reduction of yarn verification and measurement ratio in such a way.
In a further advantageous embodiment, rely on increment counter determine suction nozzle pivotable move period suction nozzle the increment of process, it is static that increment counter is arranged in the region of the actuating device of suction nozzle.Rely on this state type increment counter, reliably can determine the quantity being arranged in the increment on sensor element in the drive area of suction nozzle, this sensor element is installed relative to suction nozzle pivotable.This means, when suction nozzle pivotable leaves the control position of the suction hose contact tensioning yarn being entered suction nozzle by the reference position of zero position sensor definition, sensor element is along with suction nozzle pivotable.
In first embodiment, the station producing the weaving loom of cross winding bobbin is provided with: for being wound around the doff device of cross winding bobbin; By the suction nozzle of independent direct motor drive, described suction nozzle is in order to the yarn receiving and advanced on the surface of cross winding bobbin of having no progeny in doff; And also having control setup, control setup is such as the station computing machine be connected with zero position sensor, increment counter and yarn tensile strength sensor, relies on this station to perform according to method of the present invention.
The reference position of zero position sensor determination suction nozzle, yarn tensile strength sensor detects the suction nozzle loaded by individual driver and when is being tangential on by its suction hose the yarn be stretched between yarn tensioner and doff driven roller simultaneously.
The pivotable that state type increment counter can utilize increment to detect suction nozzle extremely accurately moves, and described increment is arranged on the sensor element with suction nozzle pivotable.
In another embodiment, station is provided with the individual driver being designed to stepper motor, is provided with increment and with the sensor element of suction nozzle pivotable and corresponding state type increment counter to replace.Thus stepper motor is provided with the device for automatic detecting step number.

In shown example embodiment, during doff process, the cross winding bobbin 5 rotatably installed is arranged in bobbin framework 8, and the surface 35 of cross winding bobbin 5 is positioned on bobbin driven roller 9, and relies on wipe contact to be transmitted by bobbin driven roller 9.
In fact, the bobbin driven roller 9 that another bobbin actuating device carrys out alternative this friction operation also can be set.
Such as cross winding bobbin 5 also can comprise direct driver.In this case, such as actuator will be arranged in the region of the shaft of bobbin that cross winding bobbin is rotated.
Independent of the type of the actuator of cross winding bobbin, the yarn 16 of advancing from textile tubes 3 to cross winding bobbin 5 in doff process is also by Yarn lateral-movement device 10 traversing, such as this Yarn lateral-movement device 10 comprises the finger-like thread-carrier 13 loaded by single electric motor actuator 14, between the both end sides of cross winding bobbin 5.
This Yarn lateral-movement device 10 is long known in weaving loom industry, such as, in DE19858548A1, have detailed description.
In region after doff device 4, be provided with the cross winding bobbin feedway 7 removed by the cross winding bobbin 5 produced.
Also as shown in Figure 1, each station 2 also comprises the suction nozzle 24 of pivotable installation and the clamp 25 of pivotable installation.
Suction nozzle 24 is mounted to rotate around S. A. 23 in a limited manner, and can be positioned on different operating positions, it has individual driver 15, and this individual driver 15 is connected to station computing machine 31 via control line 36.
Such as, independent actuator 15 can be designed to electrical motor or stepper motor.
In the exemplary embodiments, suction nozzle 24 also comprises and can be used in checking that whether successfully trial suction nozzle 24 receive the end of a thread Yarn senser 41.
In conventional Winding operations, suction nozzle 24 is usually located at the reference position I place of Sensor monitoring.
Have no progeny in doff, the suction nozzle 24 for receiving the end of a thread of advancing on the surface 35 of cross winding bobbin 5 moves 21 along pivotable to carry out pivotable and enters the end of a thread receiving position II shown in Fig. 1.
In addition, suction nozzle 24 can pivotable move for the pivotable of calibrating it and entering control position III, carries out more detailed explanation below this position by with particular reference to Fig. 3.
When the individual driver 15 of suction nozzle 24 is in motorjbrm, sensor device is needed suction nozzle 24 to be accurately positioned at its various different operating position.This means that the sensor device 43 that two fixed sensor devices 40,44 and pivotable are installed is arranged in the region of the actuating device of suction nozzle 24.
According to this example embodiment, so-called increment counter 40 and so-called zero position sensor 44 are used as fixed sensor parts.These two fixed sensors 40,44 correspond to sensor element 43, and sensor element 43 has multiple increment 45 and is therefore fixed on suction nozzle 24, and make during suction nozzle 24 pivotable, increment 45 is with suction nozzle 24 pivotable.
This means to rely on fixed type zero position sensor 44 and fixed type increment counter 40 and be provided with the pivotable installing type sensor element 43 of increment 45, reliably can determine reference position I and the end of a thread receiving position II of suction nozzle 24 if necessary.
In order to accurately determine the control position III of suction nozzle 24, the signal ii of yarn tensile strength sensor 29 is necessary, when suction nozzle 24 to be tangential on its suction hose yarn 16 be namely stretched in yarn tensioner 30 and yarn between the cross winding bobbin 5 loaded along winding direction time, this signal ii is provided.
As mentioned above, rely on individual driver 15 when needed suction nozzle 24 can be pivoted to the end of a thread receiving position II from reference position I, on the II of position, the opening of suction nozzle 24 has separated with the surface 35 of the cross winding bobbin 5 rotated along unreeling direction 37 at this time point the optimum distance a limited, and such as a is 5mm.
Describe in the introduction of specification sheets as above-mentioned, be subject in the station of the cross-winding bobbin winder of a large amount of stress during doff, often inevitably, be subject to heavily stressed parts and no longer aim at along with the time can become.
Particularly through Long-Time Service, in the region of relative sensitive, suction nozzle departs from from reference position is inevitable.
This means, if after during specific operation or after a large amount of changeover program, the installation site of inspection suction nozzle, and just carry out if necessary resetting or resetting, this optimum operation for this station is very favorable.
In suction nozzle 24; have no progeny in doff and receive the end of a thread of the so-called upside yarn of having advanced on the surface 35 of cross winding bobbin 5; and be sent to yarn splicing device 26; the risk that such as can exist here is; distance a important between trial period is received as at the end of a thread; distance a defines the distance between the opening of suction nozzle 24 and the surface 35 of cross winding bobbin 5, and this distance will change a little, and this can increase usually attempts failed quantity when receiving the end of a thread.
Unsuccessfully attempt in order to avoid this, use according to alignment method of the present invention from the beginning, the method below referring to figs. 2 and 3 in carry out more detailed explanation.
According to method of the present invention:
During batch variation occurs the machine 1 producing cross winding bobbin, usually before the actual doff process of beginning, first perform and operation is set at least one times: suction nozzle 24 is positioned at the end of a thread receiving position II best for this batch.
This means, run duration is set at this, produce the cross winding bobbin 5 of diameter such as between 130mm and 150mm.Described cross winding bobbin 5 is used as regulate bobbin and insert in bobbin framework.Then its reference position I upwards pivotable that suction nozzle 24 detects from sensor by its individual driver 15 is relied on, the sensor element 43 such as installed relative to suction nozzle 24 pivotable is exerted pressure to zero position sensor 44 at this position I, the suction hose of suction nozzle 24 moves 21 along pivotable and moves thus, and locate preferably by use mechanical separation device (not shown), make the opening of suction nozzle 24 as shown in Figure 1 relative to regulating the surface 35 of bobbin or different cross winding bobbin 5 and there is the optimum distance a detected for yarn.
In this step, rely on increment counter 43 and there is the sensor element 43 of designated increments 45, determining when suction nozzle 24 pivotable leaves the quantity of the increment 45 of suction nozzle 24 processes when the reference position I limited by zero position sensor 44 enters the end of a thread receiving position II.
So the quantity of determined increment 45 is as the indicatrix of operating position, this indicatrix is kept in the control setup of station 2, is preferably kept in station computing machine 31.
If exist and have employed desired data, this adjustment can be avoided.
Afterwards, perform and connect yarn process, then by its individual driver 15, suction nozzle 24 pivotable left the reference position I shown in Fig. 2 and enter control position III, at this position I, zero position sensor 44 is by sensor element 43 action.
When the suction hose of suction nozzle 24 is tangential on the yarn 16 between the cross winding bobbin 5 being stretched in yarn tensioner 30 and load along winding direction, arrive the described control position III shown in Fig. 3, this add immediately by yarn tensile strength sensor 29 current detection to the tension force of yarn 16.
As shown in the figure, yarn tensile strength sensor 29 sends corresponding yarn tension signal ii to station computing machine 31 through signal wire (SW) 46, and this stopped the actuator 15 of suction nozzle 24 immediately.
During suction nozzle 24 forward pivotable, the sensor element 43 be connected with suction nozzle 24 is removed from zero position sensor 44, and increment counter 40 also reads the increment 45 be arranged on sensor element 43.This means, increment counter 40 determine since suction nozzle 24 left its reference position I limited by zero position sensor 44 and sensor element 43 play enter control position III the quantity of increment 45 of process.
The controlling valu determined in such a way represents calibration reference value, and this reference value is also preferably kept in station computing machine 31.
In the time after a while, namely when new lot has run certain hour section, perform connecing yarn process or after the cross winding bobbin 5 producing predetermined quantity, then performing calibration by suction nozzle 24 qualified of specific quantity.
Suction nozzle 24 pivotable is left its reference position I of being determined by sensor and is entered control position III thus.
In addition in described calibration qualified period, rely on increment counter 40 to determine the quantity of increment 45 of process, and set up the actual alignment value that can limit the current adjustment state of suction nozzle 24.
By more described actual alignment value and the calibration reference value previously determined, set up a calibration variables, the pivotable of the suction nozzle 24 that described variable can be used between the reference position I of sensor detection and the end of a thread receiving position II moves in the subsequent calibrations of 21.
This means, this calibration can check whether the angle of suction nozzle 24 there occurs movement relative to the original angle position of suction nozzle, and then the words of necessity calibrate it.
When using according to method of the present invention, generally can detect the change of the optimum distance a between the opening of suction nozzle 24 and the surface 35 of cross winding bobbin 5 in a single stage, in this stage, the end of a thread verification and measurement ratio of reduction not yet makes a significant impact.
In this case, it is envisaged that except incorrect the end of a thread receiving position of suction nozzle, the verification and measurement ratio of reduction also can be caused by the fluctuation of such as negative pressure, line barrel structure, yarn tension etc.
But, the opening at least can eliminating suction nozzle according to the present invention to cross winding bobbin surface between the cause of incorrect distance.
Finally, especially should be mentioned in that, can also perform according to method of the present invention by the embodiment of the station revised slightly.
Replace as suction nozzle 24 and fixed sensor device 40,44 (corresponding to be provided with increment 45 and with the sensor element 43 of suction nozzle 24 pivotable) the electrical motor of individual driver 15, such as, stepper motor also can be used as the individual driver 15 of suction nozzle 24, and can arrange control setup 31, control setup 31 is configured to the number of times determining the switch step performed by stepper motor during pivotable process.
