Description
Technical field
The present invention relates to a kind of equipment that is used to prepare bobbin (spool), described bobbin will be supplied to sutomatic winding machine.
Background technology
The widely used technology of the yarn of production is arranged in the industry, at F/s is spinning (the being typically ring spinning) stage of producing the bobbin of yarn, it is second winding portion thereupon, at second winding portion, with yarn unwinding from its bobbin, eliminate its defective and be wound up into again on the reeling frame (reel), described reeling frame comprises more substantial yarn and corresponding with the basic quantity of processed bobbin.Winding process is more faster than spinning process, and the production of a large amount of spinning units of thousands of units magnitude can be handled in a small amount of winder unit of tens of thus units magnitude or the station of reeling.
In full yarn axis to the empty cop (empty quill) of up-coiler and bobbin to the conversion between two operations of spinning machine, promptly pass through the chest (trolley boxes) of belt wheel or in so-called " line weaving up-coiler (thread spin-winder) ", understand a large amount of generations by directly and separately described bobbin being transferred to described up-coiler.Generally speaking, make package (package) that the end of their line is wound on bobbin with the revolution of setting or be wound on the base portion of the cop of bobbin on every side from the bobbin of spinning machine.
Before the station of reeling in being supplied to the coiling station that forms sutomatic winding machine, must prepare to treat the bobbin of unwinding by the operation of carrying out with many stages.Yarn must discharge from the base portion of cop or from the body of bobbin in the end on the bobbin and unwinding certain-length from the outside face of bobbin.Subsequently, the very little upper end of shearing yarn and being assembled to the bobbin cop of hindsight, when the described new bobbin unwinding of having supplied with began, described coiling station can be extracted yarn from described upper end, yarn is connected, also begins again coiling with obtainable strand end (skein-end) on the bobbin (bobbin).Not only at from the new bobbin of spinning machine and also at not fully the bobbin of unwinding all require this preparation, in sutomatic winding machine, described not fully the bobbin of unwinding regained substantially and recirculation, thereby the leftover yarn that will still be wound on them uses up.
Usually, the preparation machine of bobbin is arranged on the sutomatic winding machine, and prepare on-cycle and carry out and controlled by a control unit in its special control unit, this control unit receives from the signal of sensor (described sensor is present in the various piece that forms described equipment) continuously and sends the order that is used to carry out the various operations of described on-cycle.
The operation of this preparation bobbin before bobbin being supplied to the station of reeling is generally undertaken by keeping bobbin to be in vertical position in the set up procedure of conveying and bobbin, as for example in same applicant's patent EP 463695 and EP 1932793A1.
Not only in course of conveying but also in described preparation and unwinding operation, made bobbin keep the regulation of vertical position and do not contacted actually thus and shifted under the situation of bobbin and handle bobbin, and can avoid bobbin to expose and dirty or cause dirt via contacting with machine mechanism.In the sutomatic winding machine of more designs recently, usually the technology that adopts is, be arranged in load-transfer device or similar bolt dish (peg tray) cover keep lever in the machine servo motion mechanism by employing, whole bobbins and empty cop are moved, between spinning machine and up-coiler, move to make described bobbin and cop respectively.
As what in same applicant's aforementioned patent applications EP 1932793A1, illustrated, the F/s of bobbin beamhouse operation comprises catches the line strand end (thread skein-end) that is wound on the bobbin, and this is below with reference to being illustrated with its most wide in range term in the specification sheets of Fig. 1.
At control position, bobbin 1 to be prepared is kept upright on its bolt dish 2, and on vertical position with tailstock 3 centerings that are arranged in front of bobbin self top.
Be used to make the electric roller 5 of bobbin rotation described to be prepared to be set in front of the base portion of the bolt dish 2 that keeps bobbin 1, keep bobbin to be held and to utilize centering body (for example opposed roller 6) centering.
At described workstation, the bobbin 1 that the next-door neighbour is preparing has fixing suction nozzle with battery unit 10, fixing suction nozzle with battery unit 10 is equipped with slit 11 in the bus near bobbin 1 at it, slit 11 extends to the curved top portion 12 of suction nozzle with battery unit from the base portion of suction nozzle with battery unit, curved top portion 12 is connected in pipeline 13 with suction nozzle with battery unit, and pipeline 13 is used to be connected to concentrated aspirator; Begin to locate to insert the valve 14 that is used to realize that part flows at described pipeline 13.Preferred embodiment according to suction nozzle with battery unit 10, the vertical part that bobbin described to be prepared 1 is placed in the described suction nozzle with battery unit of front manufactures the spill cross-sectional plane that has as in the amplification details of Figure 1A, in Figure 1A, can see being provided for bobbin and comprising the part of slit 11 of described suction nozzle with battery unit, it has at the coiling portion of bobbin and causes that the strand end of bobbin is linked in the mouth 10.
In order to catch the strand end, open at valve 14 under the situation of maximum aspiration flow, supply with mouth 10 maximum aspiration negative pressure (depression) by pipeline 13.Generally speaking, keep the required negative pressure value of strand end to be in the 3500-5000 handkerchief.By making bobbin 1 along being arranged in around the bobbin or, activating electric roller 5 at the unreeling direction rotation pre-determined number of the residue line of bobbin base portion.By being applied to the strong swabbing action in the mouth 10, slit 11 has the remarkable swabbing action towards the line strand end of the bobbin of just handling, and the line strand is held from bobbin from being withdrawn in the mouth 10 on one's body.
Usually, in order successfully to catch the strand end, pumping efficiency is conclusive.Yet, the operation of finding and catching the strand end by suction often comes auxiliary by the instrument of being convenient to the strand end is separated from bobbin (for example brush unit or nail element), described instrument can be placed in the described bus front of bobbin and can vertically slide, separate with interception wire loop (loops of thread) and with wire loop, but will make bobbin 11 along one or another sense of motion rotation.This processing stage, the line that the strong suction in the mouth 10 does not allow to be sucked comes out from the slit 11 of the curve 12 of mouth 10.Have sensor in the end of mouth 10, the line that described sensor indication is sucked is present in the described mouth and strand is held successfully seizure.In case described line is captured and detects, valve 14 apertures are diminished, flow with " part " of keeping low discharge and lower negative pressure, and bobbin 1 is stopped the rotation.
Because this lower negative pressure suction, line 18 is in tension still, and can from the slit 11 of the curve 12 of mouth 10, come out (as shown in Figure 1) and enter into the opening of maintaining body 19, from this, the follow-up new field of technical activity that is used for ready strand end is fixed on the device on the described cop will begin.Generally speaking, the value of lower negative pressure that is enough to that line is come out and obtains the controlled release (in other words, line 18 still is delivered to tensioning maintaining body 19) of line from slit 11 is in the scope of 200-500 handkerchief.
Have the sensor that is used for described line in the maintaining body 19, line 18 transmission have taken place to the control unit indication of the preparation machine of bobbin in described sensor.For example, carry out the described follow-up phase of the operation of preparation bobbin can provide in same applicant's above-mentioned patent application EP1932793A1.
On the other hand, strand end sensor in being arranged at mouth 10 ends is not indicated when the first seizure stage finished and is existed under the situation of described line, under the order of the described control unit of described preparation machine, preferably keep the step of strand end, can repeat this seizure stage pre-determined number by progressive adjustment.If this repetition successfully, then described bobbin is dropped and/or manually prepares by the workman.
Under any circumstance, the seizure stage that repeats to twist end has lost quite a lot of time and has been used to prepare twist the capacity rating of the described equipment of end, thereby require parallel a plurality of bobbin preparatory unit of arranging are installed in the up-coiler that comprises high quantity winder unit, thereby guarantee to supply with required bobbin to described winder unit.
Generally speaking, in described preparation machine, the handling rate of bobbin is corresponding to being no more than the 3-5 total processing time of second at each bobbin.
Thus, exist such demand, promptly guarantee to find, separate and catch the initial operation efficient maximum of strand end, thereby when attempting for the first time, just realize keeping the strand end.Generally speaking, separating and catching in the described line, maximum difficulty comes from yarn extremely crinosity or twisting, and the adjustment of described step not only relates to the mode of bobbin 1 rotation but also relates to and be provided with mode and the suction method that helps to make the described instrument that line separates.
In the prior art, according to reference scheme drawing shown in Figure 1, described suction source is from being equipped with collective's aspiration manifold of giving up-coiler, and described collective aspiration manifold is connected with pipeline 13, and utilizes valve 14 to adjust the negative pressure that is incorporated into the suction in the mouth 10.The described suction that is derived from utility does not allow high capturing efficiency, because can not increase obtainable suction negative pressure value when valve 14 is opened; On the contrary, when other mechanism of up-coiler required the suction service simultaneously, described suction was subjected to negative effect, caused this negative pressure value to reduce.The defective that described public collective aspiration manifold also exists is that the volume of oneself is quite big, and thus at having sizable inertia with the needed negative pressure variation of its bonded assembly individual unit.
