Abstract
The invention relates to such a method in which, in the course of a thread-connecting cycle, the drive device of the thread-connecting device executes a closed movement run-off of the time-coupled sequence. The object is to develop further such a method, so that the effectiveness of the splicing as a whole is increased. This object is achieved, according to the invention, in that the release of the splicing air is suppressed if the conditions necessary for a successful splicing operation are not present within the time-coupled sequence at the moment of release of the splicing air. These conditions can be the feed of the thread end located on the run-off bobbin side or run-on bobbin side, the presence of the necessary splicing pressure or of the necessary splicing temperature at a thermal splicer. In addition to the air used directly for splicing, under the conditions mentioned the opening air necessary for preparing the thread ends can also be suppressed.
Description
The present invention relates to a kind of method of carrying out the yarn connection with splicer.
At present, be arranged in the automatic winder of delegation mutually by many winder ingots position, generally all there is a Yarn twisting device each ingot position.Make comparisons with employed knotter of past, Yarn connecting almost only uses knotless loose thread to splice now.The step of splicing of this yarn, must regularly go to finish in the program of combination at one and look for the loose thread that two need connect, this loose thread makes its mutual twisted through prescinding, prepare and be incorporated in the head of splicing with the air of splicing, and restarts the original position of winder until arrival.One cover stepping program of whole Yarn splicing circulation generally is a course of action of carrying out sealing with a common transmission device.When a Yarn splicing loop ends, all of device of splicer participate in the assembly of yarn connection and get back to its original position or zero-bit again.
In addition, in a Yarn splicing cyclic process, detect the known for everyone and popularization of feeding of two loose threads.For this reason, use the yarn clearer on each cone winding position, two loose threads that successively enter yarn clearer are detected.If determine to lack the loose thread of winding bobbin this moment, then when not restarting the winder process, carry out the adjusting of Yarn splicing period.When reaching predetermined Yarn splicing period, the output fault-signal, operating personnel know that promptly a certain ingot position needs repairing.When not having the loose thread of unwinding cop, show that cop uses up, should carry out the replacing of cop.
A kind of for example method described in DE 38 24 837 C2 or DE 39 37 824 A1, basic difference between these two files is, the latter is described opposite with the former, the loose thread feeding of unwinding cop was detected before splicing, and therefore can also carry out the transposing of cop in the Yarn splicing circulation.What two kinds of methods needed jointly is for the step that repeats to stipulate, at first to close running Yarn splicing circulation, and successfully go to finish the process of splicing again in a Yarn splicing circulation thereafter.Under such and such situation, when not possessing for the step conditions needed of splicing of a success, just can't splice or just one splicing of fault arranged.For a such Yarn splicing circulation, whole energy that common Yarn splicing process is consumed are enough.
Task of the present invention is, further develops this method, and the Yarn splicing process is rationalized more.
According to the present invention, this task is so to solve, at a Yarn splicing circulation time, the transmission device of Yarn twisting device is carried out the course of action of a sealing by the stepping program that regularly engages, it is characterized in that, in the stepping program that regularly engages,, then do not discharge the air of splicing if the air of splicing discharges the step conditions needed of splicing that does not possess a success constantly.
Use method of the present invention,, can save splice air and energy fully for the sort of Yarn splicing circulation that can not obtain the effect of well splicing.In addition, by this as can be known the unsuccessful trial of splicing in advance, moment, compressed-air actuated management was not affected.If the winder ingot position of a specified quantity needs the air of splicing simultaneously, this more can embody significance.In the case, adopt the present invention's needed air pressure that can prevent to splice to drop to below the limiting value.
The present invention has done favourable expansion by the feature of claim 2 to 7.
When this side of unwinding cop lacks yarn, connect number of attempt according to the yarn of being regulated, relevant winder ingot position is saved the air of splicing once more.
As described in DE 39 37 824 A1, it is before the air of splicing discharges constantly that the feeding of unwinding cop detects, and so just can prevent unnecessary compressed air consumption when not having the cop feeding.Unwinding is intact because cop usually after for the first time unsuccessful feeding is attempted, promptly shows storage yarn on the cop, is just carrying out a cop transposing therebetween, this moment the Yarn splicing cycle interruption.In the case, after the cop transposing, a yarn of feeding does not promptly play the input action of closing the air of splicing.
With such scheme to some extent difference be, connect circulation time at a yarn, only carry out the loose thread feeding of a cop and attempt, when not having this cop to feed, must carry out tube changng in the circulation of yarn connection next time, this circulation comprises the waiting time of the new unwinding cop of feeding.According to the present invention, detect the yarn feeding of cop, be before the air of splicing discharges constantly, also can connect the release of the air that suppresses in the circulation to splice at for the first time this yarn.
New type auto bobbin winder is normally taked centralized Control pressure to the compressed air piping of supplying with each ingot position, and when pressure was lower than rated value, new yarn connection procedure starting all stopped, and the yarn Connection Step that has so begun can not interrupt.But in this case, this this section yarn strength of splicing is very low.If this yarn of splicing is unrecognized, or broken end occurs, this low quality yarn section of splicing is wound up on the bobbin, just produces in the process after inferior and breaks end.According to the inventive method, in such cases, do not supply with the air of splicing, do not produce the action of splicing, connect trial and must repeat yarn.In addition, in this case, in the Yarn splicing circulation, also saved the air of splicing.
When using a hot splicer, as when departing from the temperature margin of tolerance of regulation, above-mentioned similar situation can appear also.
If lack the success desired condition of step of splicing, can not or should not form Yarn splicing, then the backtwisting air also obtains saving as the air of splicing.Can further reduce the compressed air total flow like this.
In addition, aspect the save compressed air consumption, may also extend into the saving inspiratory capacity, if before discharging suction air, can determine to lack a certain condition of once successfully splicing in the process.In the case, when seeking the loose thread of winding bobbin, can also reduce the stress of winding bobbin.
By means of an embodiment the present invention is done detailed explanation below.Appended two figure of this paper are:
Fig. 1 is the side view of a winder ingot position of band Yarn twisting device,
The circuit diagram of the primary clustering of the Yarn twisting device that Fig. 2 system is relevant with the present invention.
At first with ingot position shown in Figure 1, contact the present invention explain the Yarn splicing method.
On an automatic winder, be arranged with the winder ingot position 1 of a specified quantity.Each ingot position 1 has a bobbin cradle 2 that supports all component.Moving two conveyer belts 8 and 9 along the ingot position.Conveyer belt 8 is carried unwinding cheese in zone, ingot position, promptly cop 4, and this cop is perpendicular to be inserted in the Caddy formula and to transport on the little pallet 3.
Little pallet 3 partly is placed on the conveyer belt with 8 of conveyer belts when it transports, this be since the width of conveyer belt less than little tray substrate width.Transport the guide plate 8 that little pallet 3 relies on avris ', it transport on conveyer belt 8, in delivering to conveyer belt 6 zones of laterally moving mutually with conveyer belt 8, just be aligned on each ingot position.
Conveyer belt 6 turns to guide roller 10 and 11, and presses the operation of arrow 7 directions.The transmission of conveyer belt 6 can be carrying out independent or grouping.This transmission also can for example be born by straining pulley and bevel gear directly by conveyer belt 8 or 9.
If before cop unwinding position, there are three little pallets 3 of transportation to be blocked on the conveyer belt 6, then just can not reach on the conveyer belt 6, because they guide in the past from the base plate limit of the little pallet 3 of the transportation that is blocked at last at the little pallet 3 of the transportation of passing through on the conveyer belt 8.Situation shown in Figure 1 is come from conveyer belt 8 conveyings with the little pallet 3 of the transportation of cop 4, and the conveyer belt 6 of being run is fast caught, and is sent in the by-path of winder ingot position 1.
A squirting bottle 17 is installed in cop unwinding position, and this bottle vertically separates, and is made up of the cage 18 that divide half-and-half two front and back.The front and back cage 18 of squirting bottle 17 can leave the supply line zone of being made up of conveyer belt 6 successively or simultaneously by liquid cylinder 13 and 19.Liquid cylinder 13 and 19 is fixed on column 12 and 20.After the cage of the squirting bottle of being handled by liquid cylinder 13 17 is pulled, on the little pallet 3 of transportation that conveyer belt 6 will be inserted with bare bobbin 5 is transported to conveyer belt 9 with avris guide plate 9 ' relative from squirting bottle 17.Conveyer belt 9 is sent to bobbin 5 and reclaims the local of bobbin 5 or directly deliver to a fine spining machine from its little pallet 3.
Then, back half cage 18 of squirting bottle 17 moves by conveyer belt 6, and retracts preceding half cage 18 of squirting bottle 17 by liquid cylinder 19.So the next little pallet of waiting for 3 of the transportation that has cop transfers to squirting bottle 17.Then, close preceding half cage 18 once more.In principle, two cage that can divide half-and-half 18 opening and closing simultaneously, this process is feasible basically.Can shorten the time-delay that causes because of the transposing cop like this.
Before air nozzle 14 and 16 up blew loose thread, one resembled scissors-like snarling back-off assembly 21 with operating means 22 unlatchings, makes loose thread can unhinderedly arrive suction nozzle 25.Under a stable condition, can install a balloon breaker 43 additional in the squirting bottle 17.At yarn feeding device 24 or in its suction nozzle 25, also can add among the figure the not grip device of expression, can maintain the loose thread that has been held when yarn feeding device 24 gyration next time with it.In addition, suction nozzle 25 can make the yarn fluffing, and yarn is unlikely like this slides out from yarn feeding device 24.
In loose thread was inserted blowing one stipulated time of back, yarn feeding device 24 was done upwards revolution, and promptly suction nozzle 25 reaches the extreme higher position shown in its figure along swing distance 33.At this moment yarn 32 is incorporated into a thread tension device 23 and a yarn clearer 27, and is incorporated into when needed and cuts off in the clamper 28.So the cop loose thread of feeding is subjected to the detection of yarn clearer.If cop is not supplied with loose thread, then above-mentioned cop should be changed.For this reason, yarn feeding device 24 is rotated down again, until suction nozzle 25 enter ready position 25 ' till.This stylish loose thread is held, and is incorporated into again as described above in the yarn clearer 27, detects this loose thread of feeding.
Certainly, when yarn feeding device again before the revolution of its extreme higher position, a suction pipe 34 is drawn the bobbin yarns from a cross winding bobbin 38, and is incorporated into yarn clearer and detects.Suction pipe 34 occupy a home position 34 ', 36 revolutions from this position along swinging track are so that draw the yarn of winding bobbin.
During beginning, when bobbin turns round, learn lack the yarn 32 that passes through after, promptly stop the rotation toward two-start screw guide axle 37, the cross winding bobbin 38 that is driven by its also stops.When the suction pipe 34 of band suction nozzle when being turned back to cross winding bobbin 38 next doors, be switched at a slow speed the backhaul shelves toward two-start screw guide axle 37 on, make the loose thread that is positioned on the winding bobbin 38 be admitted and to suck by suction pipe.After a stipulated time, suction pipe 34 be turned back to again his home position 34 '.Therefore the winding bobbin loose thread is held, and is introduced in like that in the yarn clearer 27 as described above, and is incorporated into where necessary and cuts off clamper 28.Behind the transposing cop, the cop yarn of feeding is also introduced yarn clearer 27 equally, and two loose threads of the feeding of yarn clearer identification at this moment resemble a two yarn.If fail to realize the static two yarn signals of identification with existing electronic yarn clearer or its computational analysis circuit, suction nozzle 34 can also be again distance revolution and carrying the loose thread that grips and rotating simultaneously in accordance with regulations.At this moment, the yarn of cop is introduced separately in the yarn clearer 27.By transmission device 44(Fig. 2) by the stepping program that regularly engages, carry out the course of action of a sealing, this one thread that just can detect in the yarn clearer 27 is from the loose thread of cop or the loose thread of winding bobbin.In addition, be provided with InfoLine 44 ", it is after transmission device 44 startings, and constantly each phase information with the Yarn splicing circulation is sent to winder ingot bit machine 42.
By above-mentioned technology, yarn feeding device 24 has two reciprocating traverses, and it is driven by transmission device 44 like that with the remaining part of Yarn twisting device.Even whole Yarn splicing prolongs slightly than a traverse circulation timei, the loose thread feeding of learning not have cop in a Yarn splicing circulation in this way can also directly link to each other with the transposing cop.But, so in a word, change a cop than carrying out twice Yarn splicing cycle saving time because transposing cop number of times is comparatively frequent.
When 1 operation of winder ingot position, electronic yarn clearer 27 receives a dynamic yarn signal.Yarn clearer carries out the identification of slubbing, details or two yarns.When the yarn measurement identifies two yarn or during the out-of-size limit, electronic yarn clearer 27 is a release signal, cuts off clamper 28 and promptly devotes oneself to work.So yarn is cut off, the lower end of yarn is held.This loose thread can not lose, and therefore the Yarn splicing step of then carrying out is out of question.
Usually after two loose thread feedings, promptly carry out normal Yarn splicing.At this moment two one threads be incorporated into the splicer guide depression bar 26 of a device of splicer 26 ' in.The device of splicer of this form is the known for everyone of representative as DE 31 32 895 A1.Loose thread is earlier cut short and is drawn into the yarn that is loaded on the splicing chamber upper and lower and prepared in the pipe 52 (referring to Fig. 2), carries out the loose thread backtwisting and is subjected to the traction of guide depression bar in the splicer by opposite direction, and the loose thread that produces a regulation is overlapping.Then with one or many compressed air blast splicer guide depression bar 26 ' in finish the process of splicing.
Splice finish after, yarn 32 affranchises again and is detected by yarn clearer 27 and twists with the fingers the knot quality.Tieing is in the margin of tolerance of regulation if this is spliced, and then normal winder process is proceeded.
Yarn is from upright cop 4 unwinding positions, through a balloon breaker 43 and/or a snarling back-off assembly 21, this device generally only is in so-called accelerating phase, closes when promptly winder begins, and opens in normal winder process; Yarn is again through a yarn tensioner 23, and electronic yarn clearer 27 cuts off clamper 28, then through catching yarn mouth 29 next doors, pass a yarn guiding ring 35 enter into toward two-start screw yarn guiding trough tube 37 also cross winding to tapered bobbin 38.Its sleeve of bobbin 38 usefulness remains on the bobbin cradle 39, and bobbin cradle 39 then is fixed on the balance staff 40.Can open bobbin cradle 39 by a bobbin cradle all-or-nothing piece 41 when needing.With 39 ' represent that bobbin cradle 39 is in transposing bobbin 38 back position occupied.
Catching yarn mouth 29 also links with the air-breathing horizontal pipe along whole bobbin winder installing with a suction arm 30.
Specially Yarn splicing circulation of the present invention is elaborated according to Fig. 2 below.
Each ingot position 1 of automatic winder is equipped with a control module, a winder ingot bit machine 42.The information that all winder ingot positions produce, the information of special electronic yarn clearer 27 is all received by computer 42 basically, and control signal corresponding is sent to each functional unit of winder ingot position.Winder ingot bit machine 42 be by a BDB Bi-directional Data Bus 51 ', 51 " with a central control unit, a bobbin winder computer 51 is connected.
This bobbin winder computer 51 connects circuit 50 ' monitoring by one and is configured in compressed air line 53 '/53 " on pressure monitor device 50.Pressure air source 53 as shown in the figure, compressed-air line 53 ' the air-flow terminal.
If pressure monitor device 50 demonstrates the minimum that air pressure is lower than regulation, at this moment by the bi-directional data circuit, i.e. instruction circuit 51 ' information is sent to all winder ingot bit machines 42 from the bobbin winder computer.Each winder ingot bit machine 42 is given the transmission device 44 of Yarn splicing step by control circuit 44 ' do not export starting order.When the pressure on the pressure monitor device 50 rises to again when being higher than minimum, by command link 51 ' no longer block the starting orders of Yarn splicing step to winder ingot bit machine 42.For the fault of splicing that prevents to cause because of the pressure of splicing is too for a short time, this measure is very much necessary.Really have only by above-mentioned instruction contact, could stop the starting of Yarn splicing step.The Yarn splicing step of having started is proceeded, and the parts of transmission device 44 and the Yarn twisting device handled by its are necessary for next yarn and carry and connect step and get back to zero-bit, thereby can restart a complete Yarn splicing process.From supplying with all compressed-air actuated trunk lines 53 in winder ingot position ", pick out a compressed air branch pipe(tube) 45 ', arm " is connected with device of splicer 26 with another compressed air piping 26 by valve 45.Compressed air piping 26 " air admission hole that leads to one or more passages of splicing, as popular device of splicer such.
This valve 45 is by transmission device 44 controls, and for the sake of assurance, the air of splicing should accurately provide in the moment that two loose threads are ready to splice.Also has second control circuit 45 ' " directly receive valve 45 from winder ingot bit machine 42." send when discharging the compressed air signal, can pass through control circuit 45 ' " operation of inhibition valve 45 when control circuit 45.Do not discharge compressed air, just when the more desired conditions of the process of successfully splicing do not possess, just do not carry out.
These above-mentioned conditions may relate to the details that exemplifies below:
-electronic yarn clearer 27 by a circuit 27 ', the loose thread information that the end is fed cheese or cop sends winder ingot bit machine 42 to;
-when pressure monitor device 50 shows that deviation appears in the compressed air values, he promptly by InfoLine 50 ', bobbin winder computer 51 and command link 51 ' transmission information are given winder ingot bit machine 42;
-when pressure monitor device 50 showed that deviation appears in the compressed air value, he was promptly by InfoLine 50 ", bobbin winder computer 51 and command link 51 ' transmission information are given winder ingot bit machine 42;
-when pressure monitor device 54 shows that deviation appears in the values of bleeding, he promptly passes through InfoLine 54 ", bobbin winder computer 51 and command link 51 ' transmission winder ingot bit machine 42;
-when adopting hot splicer, the splice head and/or the air applications heater heating of splicing, when the temperature excursion scope occurring, this information promptly by a temperature sensor 49 by InfoLine 49 ', send winder ingot bit machine 42 too to.
The air of splicing is discharged into splicer, guide depression bar 26 ' splice in the passage and to be discharged into device of splicer 26 similar fully, same for the air of splicing, the backtwisting air is input to be carried yarn that tipping puts and prepares to manage 52 and also be controlled.Be drawn into this yarn through the loose thread after shearing and prepare in the pipe 52, at this place's backtwisting, then loose thread mechanically, promptly among the Ben Wentu not the yarn feeding device of expression be incorporated in the passage of splicing of the head of splicing.The relevant process details of splicing is related to German patent DE 31 32 895 A1 that quoted once more.Prepare pipe 52 near two yarns that the channel end of splicing is settled, in Fig. 2, represented for wherein one with symbol, their required compressed air, be by the compressed air Trunk Line 53 of supplying with all network ingot positions 1 " branch pipe(tube) of telling 48 ', and through valve 48 and another root compressed air piping 52 ' supply.This compressed air flow into yarn downwards from the avris tangential direction and prepares the pipe 52, produces one at this tubule place for sucking loose thread and preparing the swirling eddy that loose thread is spliced.Valve 48 generally " is regulated by the control circuit 48 of transmission control device 44.But when the required condition of the step of splicing of success when not possessing, at this moment winder ingot bit machine 42 is also by preparation air that control circuit 48 ' " will not discharge by control circuit 48 " controlled.
Concerning winder ingot bit machine 42 and bobbin winder computer 51, except above-mentioned information and control circuit, also be provided with circuit with uncorrelated other additional function of the present invention.Also be to draw a series of other control circuits from transmission device 44, for example control yarn feeding device 24, the motion of the bar of the motion of suction nozzle 34 and loose thread operational processes, the separating device of two loose threads is possible and cuts out the lid that splice passage and supply yarn feeding device 24 and suction nozzle 34 air draughts are used.
Controlled the air draught of yarn feeding device 24 supplies with by control circuit 47 ' operable valve 47.In the time of need catching yarn, this valve is promptly connected the air-suction duct 31 that links to each other along the air draught transverse tube 31 of whole bobbin winder ", be communicated with simultaneously the air-suction duct 24 of yarn feeding device 24 '.
Control circuit 46 ' one of control is the valve 46 that suction nozzle 34 discharges air draught.When discharging air draught, from air draught horizontal pipe 31 connect the air-suction duct 31 that ' with the air-suction duct 34 ' connection of suction nozzle 34.
The suction air volume of air draught horizontal pipe 31 also is to test with the pressure monitor device 54 of pipeline 54 ' link to each other with air draught transverse tube 31.If when air draught pressure exceeded the margin of tolerance of a regulation, then an InfoLine 54 by pressure monitor device 54 " sent information to bobbin winder computer 51.This bobbin winder computer continues to send pressure monitor device 50 relevant compressed air information to winder ingot bit machine 42 in the same manner.So computer 42 is by the starting of command link 44 ' blockade transmission device 44.
In order to cooperate the Yarn splicing circulation of just carrying out here, valve-off 45 and 48 promptly suppresses the unlatching by each valve of transmission device 44 controls.Like this, except that the save compressed air, also reached the saving air draught.Certainly, only before each valve discharges compressed air, determined not have or do not possessed at least, can obtain above-mentioned saving for the desired condition of once successfully splicing.In order to stop the release of air draught, control circuit 46 " and 47 " is by- pass valve control 46 and 47 respectively.
The transmission device of illustrating as cam pack or camshaft among Fig. 2 44 is normally used form aspect Yarn twisting device.Certainly, within the scope of the present invention, also available other a kind of transmissions of this device substitute.In a word, for the stepping program that the timing that reaches the Yarn splicing step engages, must carry out the course of action of a sealing.
Can affirm that because the save compressed air, the total energy consumption of bobbin winder reduces.In addition, can avoid the sort of be wound in the bobbin subtle go out, and up to back process cause the breaking end fault tieing yarn of fault.
