The bolt dish 12 of full bobbin or ceases to be busy axle of having been chosen moves to the position corresponding with ceases to be busy axle supply unit then, and the ceases to be busy axle is installed on the bolt 12b.Then, bolt dish 12 that the ceases to be busy axle is installed is moved to the position corresponding with turntable 31.The bolt dish 12 that becomes the state that engages with turntable 31 is transferred energetically by the rotation of turntable 31, is moved to the position with bolt dish 12 butts of transferring earlier.
Below, equally, control device C input is confirmed submerging and outstanding state of two- piston bar 21a, 22a from the detection signal of each sensor S1a, S2a, S1b, S2b, make cylinder 21,22 actions, so that two cylinders 21,22 make transfer track 15 toward moving and reversing respectively.Thereby the bolt dish 12 on the transfer track 15 of the 2nd transfer device T2 is transported on the 2nd connecting portion 14 by each 4 ground.In addition, successively bolt dish 12 each 4 ground are supplied on the transfer track 15 of the 1st transfer device T1 from the 2nd connecting portion 14, and the bolt dish 12 that full bobbin or ceases to be busy axle will be installed is transferred to each 4 ground of the 2nd transfer device T2 from the 1st transfer device T1 successively via the 1st connecting portion 13.And, dispose both moment of determined number on two transfer device T1, T2 at the bolt dish 12 that the ceases to be busy axle has been installed, full bobbin send and the ceases to be busy axle send into end.
Then, according to the flow chart of Fig. 3, the setting that action time started under the situation that makes cylinder 21,22 action, cylinder 21 and the poor t1 of the action time started of cylinder 22 be described in proper order.
Control device C begins the drive controlling of cylinder 21,22 in step S1, the feeding of beginning bolt dish 12.The initial value Tinit that control device C will differ from t1 is set near the space part of the bolt dish 12 of bolt dish 12 turntable 31 of the 2nd connecting portion 14 and moves needed time, for example 0.6 second with common speed, and Tin and Tout is set at the identical time (for example 4 seconds).Then, control device C in step S2, the reciprocating motion of the cylinder 21,22 in 10 times under identical condition to electromagnetic valve 32,33 output driving command.In addition, based on the output signal computing of sensor S1a, S1b and sensor S2a, S2b time T in and time Tout from the stroke of each time of 1 time to 10 times.And, if 10 times stroke finishes, then control device C 10 times the mean value Tin of Tin and the time Tout of operation time respectively (N1, N10), Tout (N1, N10) after, advance to step S3.In addition, mean value Tin (N1, N10), Tout (N1, N10) be mean value under the situation of 10 times initial strokes from the 1st time to the 10th time, be later on 10 times after 10 additions number of times, promptly from the 11st time to the 20th time, from the 21st time to the 30th time ... from (10 * n-9) inferior to (10 * n) inferior mean values (wherein, n is a natural number).
The mean value Tin of control device C judgement time Tin in step S3 (N1, N10) whether be time T out mean value Tout (N1, N10) more than.If control device C mean value Tin (N1, N10) be mean value Tout (N1, N10) more than, then in step S4, will be set at initial value Tinit since the poor t1 of next time after, advance to step S5.In addition, if control device C mean value Tin (N1, N10) less than mean value Tout (N1, N10), then in step S6, will be set at since the poor t1 of next time from time T out and initial value Tinit and deduct value behind the time T in, advance to step S5 then.
Control device C in step S5, carry out from time T out deduct behind the poor t1 value whether comparison time Tin multiply by after 180/300 value greatly, promptly whether the cylinder 21 of the 1st transfer device T1 has moved the judgement more than the 180mm before the feeding of the cylinder 22 of the 2nd transfer device T2 finishes.Then, if made affirmative determination in step S5, then control device C advances to step S7.If made negative evaluation in step S5, then control device C will differ from t1 and be set at time T out and time T in be multiply by the poor of value after 180/300 in step S8, then, advance to step S7.In addition, the 180/300th, the value after the space that does not have bolt dish 12 (180mm) of the turning part of the 2nd connecting portion 14 removed with the stroke (300mm) of cylinder 21,22.
Control device C in step S7, differ from t1 whether comparison time Tout multiply by after 180/300 value greatly, judgement that promptly whether the cylinder 21 of the 1st transfer device T1 starts before the cylinder 22 of the 2nd transfer device T2 has moved 180mm.Then, if made affirmative determination in step S7, then control device C advances to step S9.If made negative evaluation in step S7, then control device C will differ from t1 and be set at time T out be multiply by value after 180/300 in step S10, then, advance to step S9.
Control device C differs from t1 in step S9 and whether difference t2 is zero above judgement, if difference t1 and difference t2 are more than zero, then advances to step S11, if difference t1 and poor t2 non-vanishing more than, then advance to step S12.Control device C advances to step S11 carried out wrong demonstration in step S12 after.So-called wrong the demonstration is to instigate for example not shown emergency warning lamp to be lighted or show error message etc. on not shown display part.In addition, even shown error message, produce obstacle can directly for the action of the 1st and the 2nd transfer device T1, T2, so the action of two transfer device T1, T2 continues yet.
Control device C has both judged whether to carry the bolt dish 12 of determined number in step S11, promptly whether the reciprocating number of times of two cylinders 21,22 has reached set number of times.And if the reciprocating number of times of two cylinders 21,22 has reached set number of times, then control device C finishes the conveying operation of bolt dish 12.If do not reach set number of times, then control device C gets back to step S2.
By above control, to electromagnetic valve 32,33 output instruction signals, so that from the action of the 1st time to the 10th time cylinder 21,22 time T in and time Tout is identical, difference t1 becomes initial value Tinit (0.6 second) like that shown in Fig. 4 A.And, the 11st time later from each (10 * n-9) inferior to (10 * n) inferior, if 10 times mean value Tin (N1 of this front, N10) be mean value Tout (N1, N10) more than, then shown in Fig. 4 B, differing under the former state state that t1 is initial value Tinit electromagnetic valve 32,33 output instruction signals.Because mean value Tin (N1, N10) be mean value Tout (N1, N10) more than, Tinit is big for ratio t1=initial value so difference t2 becomes as a result.In addition, if 10 times mean value Tin (N1 of this front, N10) less than mean value Tout (N1, N10), then shown in Fig. 4 C, to electromagnetic valve 32,33 output instruction signals, so that difference t1 becomes the (N1 from mean value Tout, N10) with initial value Tinit and deduct mean value Tin (N1, N10) value after, be that t2 becomes initial value Tinit.The result, under the situation about sending into of the sending of the full bobbin after doffing, ceases to be busy axle, even send side and the load variations of sending into side, the bolt dish 12 that does not also have the 1st transfer device T1 side can be carried bobbin via the obstacle of the bolt dish 12 of the 1st connecting portion 13 pushings the 2nd transfer device T2 side.
In addition, when stopping, the running of spinning frame board 11 carries out the adjusting of speed control 37.
In this embodiment, can access following advantage.
(1) in each cylinder 21,22, independent electromagnetic valve 32,33 is set, and controls so that the action time started of cylinder 21 postponed than action time started of cylinder 22 by control device C.Be provided with the 1st and the 2nd test section actuation time (sensor S1a, S1b and sensor S2a, S2b) of the actuation time of detecting two cylinders 21,22 respectively.Then, control device C according to by two actuation time test section detected actuation time of Tin, Tout change, revise action time started poor of two cylinders 21,22, so that the bolt dish 12 on the 1st transfer device T1 can not apply pushing force to the bolt dish 12 on the 2nd transfer device T2.Thereby, utilizing the bolt dish that moves back and forth handover 12 by transfer track 15 to carry out even send side and the load variations of sending into side, also can carrying bobbin without barrier under the situation about sending into of the sending of full bobbin, ceases to be busy axle.
(2) control device C controls two electromagnetic valves 32,33 when the driving of bobbin conveying apparatus begins, so that the poor t1 of the action time started of two cylinders 21,22 is identical with the poor t2 of action dwell time.Then, based on (being 10 times in this embodiment) each cylinder 21,22 repeatedly toward moving needed time T in, Tout, calculate the mean value toward the moving needed time of at least two cylinders 21,22, based on this value set make follow repeatedly in 21 reciprocating action time starteds of cylinder of each time.Thereby, to change the situation of the operation condition of two cylinders 21,22 with per 1 time and compare, control becomes easy.In addition, even in the operating state of each time of two cylinders 21,22, have deviation, also can become suitable condition.
(3) control device C will be repeatedly cylinder 21 the mean value toward the moving time T in that needs, with cylinder 22 toward the mean value of the moving time T out that needs relatively, set the poor t1 of the action time started of two cylinders 21,22.Under the common operating condition of spinning frame, the past moving time of cylinder 21 becomes shorter than the past moving time of cylinder 22.But, under the situation of such special operating condition of only weaving in order to reduce output, have the past moving time of cylinder 21 to become than the situation toward moving time length of cylinder 22 by one-sided spindle.In this embodiment, also can tackle for such situation.
(4) 1 stroke of the transfer track 15 that bolt dish 12 both moved off and at every turn will be set at than 4 times bigger of spindle spacing values determining deviation, will move with making bolt dish 12 each 4 times of spindle spacings.Thereby, to full bobbin send and the action frequency that makes the cylinder 21,22 of transfer track 15 reciprocating actions till the end of sending into of ceases to be busy axle becomes 1/4 of the device that moves with making bolt dish 12 each spindle spacings, the time of delivery of per 1 bolt dish 12 is shortened significantly.
(5) the guide path 27 of the 2nd connecting portion 14 dispose turntable 31 midway, thereby, by the rotation of turntable 31, in the roughly space of two sizes more than the amount (180mm) that forms bolt dish 12 midway energetically of guide path 27.Thereby, the transfer track 15 of the 2nd transfer device T2 when moving, 4 bolt dishes 12 on the transfer track 15 are sent on the 2nd connecting portion 14 smoothly.
(6) control device C will be before the feeding of cylinder 22 finishes cylinder 21 move more than the above-mentioned space 180mm and cylinder 22 move 180mm before cylinder 21 situation about starting be judged as normally, under abnormal situation, carry out the mistake demonstration.Thereby the operator can confirm wrong the demonstration and repair abnormality earlier.
Then, with reference to Fig. 5 the 2nd embodiment is described.In addition, in the 2nd embodiment, make the setting of poor t1 of action time started under the situation of cylinder 21,22 action, cylinder 21,22 in proper order different with the 1st embodiment by control device C, other structures and the 1st embodiment are same.Therefore, give identical Reference numeral and omit its detailed explanation for same part.
Control device C controls two electromagnetic valves 32,33 when the driving of the two the 1st and the 2nd transfer device T1, T2 begins, so that the poor t2 of the action dwell time of the action dwell time of the poor t1 of the action time started of cylinder 21 and the action time started of cylinder 22 and cylinder 21 and cylinder 22 is identical.Control device C based on each cylinder 21,22 of repeatedly (being 10 times in this embodiment) toward moving time T in, the Tout that needs, calculate the mean value toward moving needed time T in, Tout of two cylinders 21,22.In addition, calculate action time started of cylinder 21 repeatedly and cylinder 22 the action time started poor t1 mean value t1 (N1, N10) and the mean value t2 of the poor t2 of the action dwell time of the action dwell time of cylinder 21 and cylinder 22 (N1, N10).Then, set repeatedly each then time make cylinder 21 toward moving time the time, set so that poor t1 become mean value t1 (N1, N10) and mean value t2 (N1, simple average N10).
Shown in the flow chart of Fig. 5, control device C begins the drive controlling of the cylinder 21,22 of the 1st and the 2nd transfer device T1, T2 in step S21, the feeding of beginning bolt dish 12.The initial value Tinit that control device C will differ from t1 is set at for example 0.6 second, and Tin and Tout is set at the identical time (for example 4 seconds).Then, control device C in step S22,10 reciprocating motions with interior cylinder 21,22 under identical condition to electromagnetic valve 32,33 output driving command.In addition, based on time T in, time T out, difference t1 and the difference t2 of the stroke of each time of output signal computing of sensor S1a, S1b and sensor S2a, S2b.Then, if 10 times stroke finishes, then at 10 times the mean value Tin (N1 of operation time Tin and time Tout, N10), Tout (N1, N10) and the mean value t1 (N1 of the poor t1 of the action time started of cylinder 21,22, N10) with the action dwell time poor t2 mean value t2 (N1, N10) after, advance to step S23.
Control device C sets 10 times poor t1 then in step S23 so that its become 10 times poor t1 of front mean value t1 (N1, N10) and differ from mean value t2 (N1, simple average N10) of t2.Then, whether big than initial value Tinit control device C differ from the whether difference of big and time T out and difference t1 the judgement than initial value Tinit of t1 in step S24.Then, if made affirmative determination in step S24, then control device C advances to step S25, if made negative evaluation in step S24, then control device C advances to step S26.Control device C advances to step S25 carried out wrong demonstration in step S26 after.So-called wrong the demonstration, be meant not shown emergency warning lamp is lighted or on not shown display part, to be shown error message.
Control device C has both judged whether to carry the bolt dish 12 of determined number in step S25, promptly whether the reciprocating number of times of two cylinders 21,22 has reached set number of times.Then,, then finish the conveying operation of bolt dish 12,, then get back to step S22 if do not reach set number of times if the reciprocating number of times of two cylinders 21,22 has reached set number of times.
Thereby, according to this embodiment, except with the same advantage in (1), (2), (4), (5) of the 1st embodiment, can also obtain following advantage.
(7) control device C based on repeatedly each cylinder 21,22 toward moving needed time T in, Tout, except the mean value of time that needs in moving of two cylinders 21,22, also calculate the mean value t1 (N1 of difference of the action time started of cylinder 21,22 repeatedly, N10) and the action dwell time difference mean value t2 (N1, N10).And, setting makes cylinder 21 reciprocating actions during the time started in repeatedly each of following, set so that the poor t1 of the action time started of cylinder 21,22 becomes above-mentioned mean value t1 (N1, N10), mean value t2 (N1, N10) simple average { t1 (N1, N10)+t2 (N1, N10) }/2.Thereby the setting logic of difference t1 becomes simple.
Then, with reference to Fig. 6～Fig. 9 the 3rd embodiment is described.In addition, in the 3rd embodiment, make the setting of poor t1 of action time started under the situation of cylinder 21,22 action, cylinder 21,22 in proper order different with the 1st embodiment by control device C, other structures and the 1st embodiment are same, so give identical Reference numeral and omit its detailed explanation for same part.
In Fig. 6, show the time diagram of expression from the relation of the detection signal of the action command of control device C and sensor S1a, S1b and sensor S2a, S2b.
Shown in the time diagram of Fig. 6, control device C output action instruction is so that action time started of cylinder 22 of sending side is than Zao Δ t1 of the action time started of the cylinder 21 of sending into side and to send the action dwell time of cylinder 22 of side more Zao than the action dwell time of the cylinder 22 of sending into side.Say that at length the output action instruction is so that the time started of feed motion is identical in both in time started and the dwell time of sending side Δ t1 morning, return action.Obstruction for fear of the bolt dish 12 of the 1st connecting portion 13 of the terminal GE of gear need have poor Δ t2 (＞0) in the action dwell time of two cylinders 21,22.In addition, be because the action ratio of the piston rod 22a of cylinder 22 finished in the end of output time of instructing through the feeding of setting behind the given time from the output time started in advance ly evening detection time of the concluding time ratio sensor S2a that feeding is instructed in sending the side action command.
Along with full sending of bobbin and sending into of ceases to be busy axle, act on the load change on the cylinder 21,22.And under most situation, the load of duty factor cylinder 22 sides of cylinder 21 sides is little.Control device C is via the action time started of electromagnetic valve 32,33 control cylinders 21,22, and the action dwell time of cylinder 22 of side is more Zao than the action dwell time of the cylinder 22 of sending into side, promptly poor Δ t2 is just (＞0) so that send.
At bolt dish 12 is in the test running of empty state, the compressed-air actuated feed speed of governing speed controller 37 so that send into reciprocal time of 1 stroke of the cylinder 21 of side become 6.6 seconds, reciprocal time of 1 stroke of sending the cylinder 22 of side becomes 6 seconds.And, control device C as full bobbin sending and the ceases to be busy axle send into beginning the time the initial value Δ t1 (0) of poor Δ t1 of action time started of cylinder 21,22, be set at bolt dish 12 with mobile needed time, 0.6 second near the space part (180mm) of the bolt dish 12 of the common speed turntable 31 of the 2nd connecting portion 14.
Then, control device C full bobbin send and the ceases to be busy axle send into beginning after, to making 21,22 reciprocating motions of two cylinders repeatedly till (being 10 times in this embodiment), setting value Δ t1 (N1 with the poor Δ t1 of action time started of two cylinders 21,22 of each time, N2) be set at initial value Δ t1 (0), come control cylinder 21,22.Then, per obtaining for 10 times from the mean value Δ t2 (N1 of the difference of the action dwell time of 10 times the cylinder 21,22 before 11 times before 20 times, N2), with mean value Δ t2 (N1, poor Δ t2 ' N2) from the difference of the action dwell time of 10 times the cylinder 21,22 before 1 time before 10 times.Then, based on difference Δ t2 ' whether than zero big judgement set difference Δ t1 (N1, N2).But, at the poor Δ t1 (N1 that sets from the 11st time to the 20th time, N2) under the situation, promptly when finishing for the 10th time, set 10 times poor Δ t1 (N1 then, N2) under the situation and since do not have the front from the data before 11 times before 20 times, so from the 1st time to the 20th time with Δ t1 (N1, N2) be set at initial value Δ t1 (0), control cylinder 21,22.
Below, according to Fig. 7 and flow chart shown in Figure 8, poor Δ t1 (N1, establishing method N2) of the action time started of two cylinders 21,22 is described.
Control device C begins the drive controlling of cylinder 21,22 in step S31, the feeding of beginning bolt dish 12.The initial value Δ t1 (0) that control device C will differ from Δ t1 is set at for example 0.6 second, and is set at, and makes the feeding instruction output time started of sending side than the Zao Δ t1 output of the feeding instruction output time started of sending into side.
Then, control device C in step S32,20 reciprocating motions with interior cylinder 21,22 under identical condition to electromagnetic valve 32,33 output driving command.In addition, based on the time T out and the difference t2 of the stroke of each time of output signal computing of sensor S1a, S1b and sensor S2a, S2b.If the release of the cylinder 21,22 till the 20th time, then control device C advances to step S33, obtain from the mean value Δ t2 (1 of the difference of the action dwell time of 10 times the cylinder 21,22 before 11 times before 20 times, 10), with poor Δ t2 ' from the mean value Δ t2 (11,20) of the difference of the action dwell time of 10 times the cylinder 21,22 before 1 time before 10 times.
Then, whether control device C differs from Δ t2 ' than zero big judgement in step S34.If difference Δ t2 ' ratio zero is big, then the poor Δ t1 (21,30) of action time started of 10 times in step S35, will following of control device C be made as initial value Δ t1 (0) and poor Δ t2's ' and after, advance to step S36.If difference Δ t2 ' is that then control device C advances to step S37 below zero, the poor Δ t1 (21,30) of action time started of 10 times following is made as initial value Δ t1 (0) after, advance to step S36.
