Supply position M2 is the position when bare bobbin 17 is supplied with reel cage arms 18, and at this moment, reel cage arm 18 is to accept on the C4 of position.And reel cage arm 18 is pushed by reel cage motion arm 40, makes the reel cage arm 18 that is in starting position C1 or completely rolls up position C2 when cop extracting position C3 topples over, and reel cage motion arm 40 is moved to extracting position M3 through supplying with position M2.Here, when bare bobbin 17 is supplied with reel cage arms 18, supply with on the M2 of position, reel cage motion arm 40 also opens to the reel cage arm 18 that moves axially, makes of fulcrum shaft 61, form by bobbin anchor clamps 30 carry out can be with bare bobbin 17 to reel cage arm 18 condition of supplying.In course of action is doffed in execution, make reel cage arm 18 when cop extracting position C3 topples over, when supplying with position M2, reel cage motion arm 40 does not make reel cage arm 18 open at reel cage motion arm 40.
Extracting position M3 is in course of action is doffed in execution, pushes reel cage arm 18 and the position of reel cage motion arm 40 when making it swing to cop extracting position C3 by reel cage motion arm 40.On extracting position M3, reel cage motion arm 40 also opens to the reel cage arm 18 that moves axially, makes of fulcrum shaft 61, the coiling package 6 that will remain on the full volume on the reel cage arm 18 is taken out.Reel cage motion arm 40 is opened just at reel cage motion arm 40 reel cage arm 18 to be in when supplying with position M2 and extracting position M3, on other positions, reel cage arm 18 is being held blocking.
As shown in Figure 3, being arranged on three drive member such as suction arm 20 on the doffing device 3, bobbin anchor clamps 30, reel cage motion arm 40 is to accept to be arranged on the transmission of power of the single motor 70 on the doffing device 3 and drive in linkage.The output shaft of motor 70 is connected with main drive shaft 71, with power branch, drives suction arm 20, bobbin anchor clamps 30, reel cage motion arm 40 by this main drive shaft respectively.This motor 70 is that make can be just/despun, and make main drive shaft 71 just change, reverse as required, make the driving direction of suction arm 20, bobbin anchor clamps 30, reel cage motion arm 40 just change, reverse.
And, on the power transfer path of each drive member, the driven member of cam and this cam is being provided with from motor 70 in contact as drive source, above-mentioned cam be by connecting rod can transferring power ground be connected with motor 70, above-mentioned driven member is to connect into the energy transferring power with each drive member.In power transfer path suction cam 72, suction driven member 29 are being set from motor 70 to suction arm 20.Specifically, this suction is the members that are configured in the end of the connecting rod that suction arm 20 is supported and driven or arm midway etc. with driven member 29.In power transfer path anchor clamps cam 73, anchor clamps driven member 39 are being set from motor 70 to bobbin anchor clamps 30.In power transfer path motion arm cam 74 and motion arm driven member 49 are being set from motor 70 to reel cage motion arm 40.
And suction arm 20, bobbin anchor clamps 30, reel cage motion arm 40 utilize cam and can drive off and on, are driven in linkage mutually, and the actual driving moment or driven time-amplitude are different mutually.
Here, bobbin anchor clamps 30 and reel cage motion arm 40 are the structures that make motor 70 drivings that only are configured drive source.Relative therewith, on suction arm 20,, on above-mentioned motor 70 bases, cylinder 75 is being set also as its drive source.This cylinder 75 accepts to be arranged on driving as air compressor 76 gas supplied of gas supply source on the doffing device 3, and the leading section of suction arm 20 is controlled to respect to rearward end can advance and retreat (the front end arrival that makes suction arm 20 is the distant place).And air compressor 76 also can become the drive source of the suction pipe 21 that is arranged on the suction arm 20.
Above-mentioned main drive shaft 71 is fixed on suction with on the cam 72, is revolved by main drive shaft 71 and turns around, makes suction to revolve with cam 72 to turn around.Revolve with cam 72 by suction that the driving of turning around to suction arm 20 means in the action of doffing, the driving in 1 cycle of suction arm 20.Equally, also making to be revolved by main drive shaft 71 turns around, can make anchor clamps to revolve the structure that turns around with cam 74 with cam 73 or motion arm.And, form to revolve to turn around and make the doff driving in 1 cycle in the action of bobbin anchor clamps 30 or reel cage motion arm 40 by main drive shaft 71.
As mentioned above, main drive shaft 71 is to revolve and turn around in the action of doffing each time, still, and in the action of once doffing, main drive shaft 71 has situation about repeatedly temporarily stopping, and makes main drive shaft 71 self become the structure that is intermittently driven.So-called this occasion that stops mainly is that cop is when taking out reel cage and opening, when yarn takes out action.Owing to when cop takes out reel cage and opens and yarn when taking out action, in the external device (ED) of doffing device 3, will carry out the action of spended time, thereby main drive shaft 71 is stopped itself, to obtain the activity duration.And, on the position of rotation of main drive shaft 71, the position in when beginning action of will doffing position of rotation R1 during as standby, position of rotation R2 when take out as cop the position when cop is taken out reel cage and opens, the position of rotation R3 when yarn is taken out position of rotation when moving and takes out as yarn.
So-called cop takes out and is meant following occasion when reel cage is opened.Reel cage arm 18 when being in the cop extracting position C3 that the coiling package 6 of carrying out full volume takes out and carry out that new bare bobbin 17 supplies with accept position C4 the time be opened for twice.Specifically, reel cage arm 18 be in full volume position C2 originally, be in will full volume the state that keeps of coiling package 6, then move it cop extracting position C3 and the cop that carries out the coiling package 6 of full volume takes out.After this, when turning back to starting position C1, the supply of accepting to accept on the C4 of position bare bobbin 17 in the front.That is to say, during the taking-up of the coiling package 6 of the full volume among so-called cop takes out twice of being meant reel cage arm 18 when reel cage is opened when opening (cop extracting position C3).(accepting position C4) is when opening as the Cylinder feeder reel cage during with the accepting of the bobbin 17 of sky.
Because cop takes out reel cage when opening, carry out the transfer operation of the coiling package 6 of full volume by the shifting apparatus that not have expression among the figure, during with the bobbin 17 of supplying with skies by bobbin anchor clamps 30 (when the Cylinder feeder reel cage is opened) compare, more time-consuming.Therefore make such structure, promptly, also long when opening than Cylinder feeder reel cage when cop takes out reel cage and opens, can main drive shaft 71 be stopped itself the open mode of reel cage arm 18, with the activity duration of guaranteeing to be undertaken by above-mentioned shifting apparatus with keeping.
Time when opening with respect to cop taking-up reel cage in the present embodiment, is that the time about 4.5sec (second), when the Cylinder feeder reel cage is opened is about 3.5sec (second).Promptly, both difference is the time about 1sec (second), and is suitable with the dwell time of main drive shaft 71.
And so-called yarn to be suction arm 20 when taking out action be in yarn catch position S2, when catching from the spun spinning 5 of the spinning device of air type 8 by suction pipe 21.Dwell time when yarn takes out action is about 1.5～3.0sec (second) in the present embodiment.
On above-mentioned doffing device 3, be provided with: catch the acquisition equipment 20, bobbin shifting apparatus 30, reel cage operating means 40 of the yarn that is taken out by yarn and whether above-mentioned yarn acquisition equipment 20 is caught the yarn detecting sensor 23 that the yarn that is removed detects, also be provided with the control device that does not have expression among the figure, it is when this yarn detecting sensor 23 does not detect yarn, is controlled to and does not carry out the later action of above-mentioned bobbin move loading action and revert to original state immediately.
Below, carry out the explanation of summary with reference to Fig. 4, to the method for automatic doffing operation in the present embodiment.This method for automatic doffing operation is in order, takes out that operation step 1000, yarn are taken out operation step 2000, repiece operation step 3000 and the cyclic process that revert to original state again through cop.That is to say that it is consistent that the state that makes repiece operation step finish time and cop take out the state of the zero hour of operation step.In this method for automatic doffing operation, taking out operation step at yarn has when improper, carries out the recurrence to original state (cop takes out the zero hour of operation step) without the repiece operation step.Carry out the above-mentioned operation that returns to original state and be called counter-rotating recurrence operation 4000.Here, being called counter-rotating is that the direction of rotation of the main drive shaft 71 (motor 70) of each drive member (suction arm 20 etc.) of driving doffing device 3 is inverted because return in the operation 4000 in this counter-rotating.
And, for whether end repiece operation step 3000, the judgement that returns operation 4000 of reversing is to be undertaken by the two-stage.Earlier after yarn takes out operation step 2000, judge that yarn takes out whether success of action.Take out when having moved successfully at yarn, still in statu quo enter into repiece operation step 3000.When yarn has taken out baulk, judge whether the frequency of failure reaches predetermined repeatedly (being 2 times in the present embodiment).Under the occasion of the 1st failure, carry out yarn again and take out operation step 2000.Under the occasion of the 2nd failure, enter into counter-rotating and return operation 4000.
Below, with reference to Fig. 5 and Fig. 6～Fig. 8, explain the order of the action of doffing.Fig. 5 describes the flow process of the action of doffing, and Fig. 6, Fig. 7 are described in the appearance of the doffing device 3 of the particular moment in the progress of moving of doffing.Here, making progress each accompanying drawings such as Fig. 6～Fig. 8 of corresponding state with reference to Fig. 5 and expression and flow process moves to doffing and describes.
Doffing device 3 be make can walking between many weaving units 2, be parked in the weaving unit 2 that sends the action request of doffing the front, and this weaving unit 2 between the action of doffing.This doff action request certain the weaving unit 2 in, send when coiling package 6 becomes full volume.
Fig. 6 is the doff appearance of doffing device 3 in when beginning action of expression.At this moment, suction arm 20 is in that position of readiness S1, bobbin anchor clamps 30 are in position of readiness B1, reel cage motion arm 40 is in position of readiness M1.This action of doffing is (step 101 of Fig. 5) that the control part by spinning machinery 1 will doff and begin when the action commencing signal sends to the control part of doffing device 3.
Before this doffs action beginning, yarn takes out action (spinning spinning 5 from the spinning device 8 of air type) in case finish, that weaving unit 2 of the action of then doffing just is in the state that stops operation.
Fig. 7 is the appearance that the expression yarn takes out the doffing device 3 when moving.From state shown in Figure 6 proceed to till the state shown in Figure 7 during this period of time in, carry out the action of from step 102 to step 110 (Overall Steps numbering therebetween).
When above-mentioned control part receives when doffing action commencing signal (step 101), makes above-mentioned main drive shaft 71 rotations drive (step 102).During above-mentioned cop took out action, main drive shaft 71 was rotated, position of rotation R1 (step 101) during from standby, when taking out through cop position of rotation R2 (step 103) and when yarn takes out position of rotation R3 (step 106).Corresponding, begin to drive suction arm 20, bobbin anchor clamps 30, reel cage motion arm 40.
From the rotation (step 102) of main drive shaft 71, suction arm 20 is driven to yarn catch position S2.Temporarily the stopping (step 103) of main drive shaft 71 before arriving yarn catch position S2, when corresponding above-mentioned cop takes out reel cage and opens and temporarily stopping, and begin (step 104), make suction arm 20 accept the operation of being stretched by the driving of said cylinder 75.Through after step 103 or the step 104, make suction arm 20 arrive yarn catch position S2 (step 105), become to former state yarn and take out the holding state (step 106) that moves.Position of rotation R3 when at this moment (step 106) main drive shaft 71 is in yarn and takes out, its rotation are stopped temporarily.
Bobbin anchor clamps 30 are that the rotation at main drive shaft 71 begins (step 102) back, stops (step 103) at main drive shaft 71 temporarily and begin to drive, arrive bobbin extracting position B2 (step 107) afterwards.
Reel cage motion arm 40 is to be driven after the rotation of main drive shaft 71 begins (step 102), arrives extracting position M3 (step 108) from position of readiness M1 through supplying with position M2.Corresponding main drive shaft 71 stop (step 103) temporarily, reel cage motion arm 40 is in extracting position M3 ground continuation halted state as before.As mentioned above, under reel cage motion arm 40 is in the state of extracting position M3, reel cage arm 18 becomes open mode.And, continuation time of this open mode is added carry out longways temporarily the stopping of main drive shaft 71 (step 103), so that do not hinder the taking-up when opening (above-mentioned cop takes out reel cage) of full volume package 6.
And the side of unit 2 that weaves, the rotation of corresponding main drive shaft 71 begins, carries out yarn and takes out warming-up exercise (step 110).This yarn take out warming-up exercise specifically be meant in the spinning device 8 of air type, for spinning 5 the operations of being undertaken by aerojet such as nozzle cleaning that are equipped with that spin.
In a single day position of rotation R3, this rotation are stopped (step 106) temporarily when main drive shaft 71 arrives the yarn taking-up, just become and can take out the state that action is shifted to yarn.Under this state, carry out yarn and take out action, promptly, spin spinning 5 and catch above-mentioned spinning 5 by suction pipe 21 from the spinning device 8 of air type.
This yarn takes out action to be in the action of once doffing, to carry out secondary at most.The first time yarn take out in the action, do not having under the occasion of undesirable condition, promptly, successfully carry out yarn when catching, just do not carry out secondary yarn and take out and move by suction pipe 21.And when the second time, yarn taking-up action was also failed, the recurrence to original state (holding state) was interrupted, is carried out in the action of will doffing.
Arrive this, in the spinning device 8 of air type, earlier carry out (step 111) for the first time yarn take out action (spinning of spinning 5).At this moment, catch spinning 5, carry out air attraction with the suction arm 20 that is in yarn catch position S2 with suction pipe 21.
On suction pipe 21, setting up yarn detecting sensor 23, can detect yarn with this yarn detecting sensor 23 (Fig. 3) and whether attracted in the suction pipe 21.
By yarn detecting sensor 23 according to the first time yarn take out action, judge that suction pipe 21 in whether yarn detects successful (step 112).Be judged to be yarn when taking out successfully, entering into the processing of step 113; Be judged to be yarn when taking out failure, entering into the processing of step 114.
Here, so-called in suction pipe 21 yarn detect and successfully be meant spinning operation or all being that success is carried out of the spinning 5 undertaken by the spinning device 8 of air type by will being caught of carrying out of suction pipe 21 by the yarn of spun spinning 5.Also be to mean, be suitable for spinning 5 to bobbin 17 repieces undesirable condition such as not to be cut off halfway, to attracted in the suction pipe 21.On the other hand, so-called suction pipe 21 in yarn to detect the occasion of failing be to be equivalent to spin 5 the occasion that operation failure or yarn are caught failure that spins.
When yarn detected successfully, main drive shaft 71 rotations of position of rotation R3 drove (step 113) in the time of will being in yarn and taking out, and turned back to position of rotation R1 (step 115) when being the standby of position of original state.At step 101, the main drive shaft 71 of position of rotation R1 when being in standby,, carried out the release of once rotating, doff in the moment of step 115.
The direction of rotation of the main drive shaft 71 when moving problem does not take place doffing here, is taken as positive veer.So-called problematic occasion is meant for example, in the occasion that yarn takes out in the action, yarn detects final (carrying out secondary in the present embodiment) failure, do not carry out the occasion of repiece action.The direction of rotation of the direction of rotation of the main drive shaft 71 during therefore, from step 102 to step 106 or the main drive shaft 71 during from step 113 to step 115 all is positive veer.
The appearance of the doffing device 3 when Fig. 8 is the action of expression repiece.The action of this repiece in step 113 to carrying out between the step 115, promptly, carry out during position of rotation R1 when position of rotation R3 turns back to standby when yarn takes out at main drive shaft 71.
In this repiece action, carry out operation as described below.Reel cage motion arm 40 was returned to from extracting position M3 and supplied with position M2 before this, will be in the reel cage arm 18 of accepting position C4 and open.Along with bobbin anchor clamps 30 are supplied with bare bobbins 17 near reel cage arm 18 and are maintained on the reel cage arm 18.But also make suction arm 20, and the bobbin 17 that is maintained on the reel cage arm 18 of accepting position C4 is carried out the repiece operation near reel cage arm 18.This repiece operation utilization is arranged on coiling device 22, the bobbin 17 that remains on the reel cage arm 18 is rotated carry out by being arranged on friction roller (not have expression among the figure) on the doffing device 3 on the suction arm 20.
After the repiece that newly remains on the bobbin 17 on the reel cage arm 18 finished, position of rotation R1 when the standby returned, makes suction arm 20, bobbin anchor clamps 30 and reel cage motion arm 40 turn back to position of readiness S1, B1, M1 respectively along with main drive shaft 71.Suction arm 20 to the recurrence of position of readiness S1 be finish the back in repiece, stop the driving of said cylinder 75, the state that is contracted with suction arm 20 carries out.And, along with reel cage motion arm 40 to the recurrence of position of readiness M1, make reel cage arm 18 revert to starting position C1.Finish to doff action as described above.
Below, illustrate in the occasion of judging that yarn takes out in the action success or not (step 112) for the first time, yarn detects failure.At this moment, carrying out for the second time, yarn takes out action, the time interval suitable with this time of implementation is held in the state that is still in position of rotation when yarn takes out with main drive shaft 71, similarly carries out yarn with above-mentioned steps 110 and takes out warming-up exercise (step 114).
Then, carrying out for the second time, yarn takes out action (spinning of spinning 5) (step 116).It is with step 111 in the yarn first time take out the same operation of action.
According to the second time yarn take out action, judge similarly that with the judgement of step 112 whether yarn detects successful (step 117) suction pipe 21 in.Be judged to be yarn when taking out successfully, entering into the processing of step 113; Be judged to be yarn when taking out baulk, entering into the processing of step 118.When the processing that enters into step 113, use with above-mentioned same order, carry out yarn repiece action and finish to doff action.
When the second time, yarn took out baulk, in the action of doffing specifically, with repiece operation reduction, make doffing device 3 revert to original state.Promptly, make the main drive shaft 71 of position of rotation R3 when being in the yarn taking-up reverse (step 118) position of rotation R1 (step 115) when turning back to standby.At this moment, the direction of rotation of main drive shaft 71, the direction of rotation when moving with respect to doff out of questionly, when carrying out the action of yarn repiece are opposite.
When just changeing in the present embodiment,, the rotation amount of main drive shaft 71 position of rotation R1 position of rotation R3 when yarn takes out during from standby is the degree of rotation 1/3 circle.
Therefore, take out baulk at yarn, do not carry out the repiece action and when doffing device 3 being revert to doff the holding state of action, the rotation amount that makes the side that the main drive shaft 71 of position of rotation R3 when being in yarn and taking out reversally returns is than just changeing lacking of returning, being that efficient is higher.In the spinning machinery 1 that carries out at a high speed weaving, the missionary society that returns needed several seconds produces bigger difference.
And, when making main drive shaft 71 just change, make doffing device 3 to revert to doff the holding state of action, need not carry out the order that yarn takes out action.So whether cotton sewing thread on cop taking-up action is not failed, by bobbin anchor clamps 30 bare bobbin is supplied to batching apparatus 10, when doffing action in the back again, must carry out so-called operation of bare bobbin 17 being removed from batching apparatus 10.This is because when this bare bobbin 17 not being removed, and when doffing action in the back again, this bare bobbin 17 will similarly be transferred with the conveying of the coiling package 6 of common full volume.
Even when making main drive shaft 71 counter-rotating, if position of rotation R1 (step 115) when main drive shaft 71 arrives standbies, then suction arm 20, bobbin anchor clamps 30 and reel cage motion arm 40 etc. also turn back to position of readiness S1, B1 and M1 separately.And reel cage arm 18 also revert on the C1 of starting position.And doffing device 3 revert to original state.
Below, with reference to Fig. 9 illustrate by the success of the action of doffing/unsuccessful determine in case of necessity between difference.Fig. 9 (a) is that for the first time yarn takes out and moves successfully and the time diagram when moving successfully of doffing, under the occasion of present embodiment, suppose with yarn take out the needed time of action get into 2.0sec (second), then this doffs, and to move needed be 13sec (second) between in case of necessity.As mentioned above, the action of doffing is made of cop taking-up action, yarn taking-up action, repiece action, and wherein, cop taking-up action wants 4.5sec (second), yarn taking-up action to want 2.0sec (second), repiece action to want 6.5sec (second).
Fig. 9 (b) is that yarn takes out the time diagram that moves successfully, doffs when moving successfully, when yarn takes out baulk for the first time for the second time.Under the occasion of present embodiment, take out action with yarn for the second time and making and doff when move successfully, this doffs, and to move needed time be 15sec (second).Wherein, the cop taking-up is moved and is wanted 4.5sec (second), yarn takes out to move and wants 2.5sec (second), the yarn taking-up action second time to want 2.0sec (second), repiece action to want 6.5sec (second) for the first time.Promptly, yarn takes out action and must carry out once more, just making doff the desired necessary time ratio of action by the first time yarn take out action and making the successful occasion of the action of doffing also grow that a yarn taking-up to move desired time.
Fig. 9 (c) is the occasion of baulk of doffing, and yarn takes out the time diagram of the occasion that action all fails promptly, for the first time and for the second time.Under the occasion of present embodiment, when doffing baulk, revert to original state (holding state) desired in case of necessity between for 12sec (second).Wherein, cop takes out that 4.5sec (second) is wanted in action, yarn takes out action to want 2.0sec (second), yarn taking-up for the second time to move and want 2.0sec (second), revert to the desired time of original state be 3.5sec (second) for the first time.Though make simply and above-mentionedly revert to desired time of original state and cop to take out the desired time of action consistent, but because in the present embodiment, cop takes out in the action and comprising the time that main drive shaft 71 is stopped, thereby the desired time of above-mentioned recurrence just becomes shorter.As mentioned above, guarantee when cop taking-up reel cage is opened, the activity duration with the full coiling package of rolling up 6 taking-up usefulness, to be provided with the time that main drive shaft 71 is stopped especially.
Can be clear that as described below some from the comparison of above-mentioned three time diagrams.At first, under the occasion (Fig. 9 (c)) of failure of doffing, because in doffing device 3, do not carry out repiece action, make main drive shaft 71 reversally revert to original state, thereby just move occasion (Fig. 9 (the b)) weak point that makes the success of doffing in case of necessity than taking out with cop for the second time.If the occasion of reversally not carrying out repiece action with main drive shaft 71 similarly, make main drive shaft 71 revert to the occasion of original state with just changeing, when then doffing baulk the desired time just with by the second time cop take out to move and equate when making doffs moves successfully.Promptly, shortened between in case of necessity repiece move the desired time and return by the counter steer original state of main drive shaft 71 the desired time difference that partly.
And, under the occasion of present embodiment, with doff relevant each of action in case of necessity between on the length relation of (cop takes out the necessary time of action etc.), the occasion of the baulk of doffing (Fig. 9 (c)) the desired time (12sec) than by the first time yarn take out action the successful desired time of occasion (13sec) of the action of doffing also lacked.
