The correction front target location instruction Pt of crank motion thread-carrier 61 be used to indicate when crank motion thread-carrier 61 moves back and forth through time displacement.The correction front target location instruction Pt of crank motion thread-carrier 61 carries out predetermined set for each rotative speed Bv of bobbin B.The correction front target location instruction Pt of crank motion thread-carrier 61, utilize the crank motion control part 81 playing function as target location instruction determination section, be always updated to the correction corresponding with the rotative speed Bv of bobbin B front target location instruction Pt in the position control cycle of each crank motion thread-carrier 61.
In addition, as shown in Figure 2 A, the correction front target location instruction Pt of crank motion thread-carrier 61 is configured to, and when the rotative speed Bv of bobbin B increases, the traversing speed of crank motion thread-carrier 61 also increases.The correction front target location instruction Pt of crank motion thread-carrier 61 is configured to, and describes roughly sinuous track reciprocal between an end Be of bobbin B (package P) and the other end Be centered by initial point O.
According to such structure, as shown in Figure 2 A and 2 B, when the rotative speed Bv of bobbin B increases, the crank motion thread-carrier 61 traversing speed that often makes a round trip all increases.When the rotative speed Bv of bobbin B is constant, crank motion thread-carrier 61 is constantly driven with the traversing speed of regulation.
Instruction Ps in target location after the correction of crank motion thread-carrier 61, when indicating crank motion thread-carrier 61 crank motion obtained according to the correction of crank motion thread-carrier 61 front target location instruction Pt and target location correction Cp through time displacement.In other words, instruction Ps in target location after the correction of crank motion thread-carrier 61 is the instruction using the correction of target location correction Cp to this crank motion thread-carrier 61 front target location instruction Pt to revise.
As shown in Figure 2 A, after the correction of crank motion thread-carrier 61, target location instruction Ps is configured to, the state of phase deviation relative to the correction of this crank motion thread-carrier 61 front target location instruction Pt.Thus, the track revised represented by rear target location instruction Ps followed by crank motion thread-carrier 61 as target, thus the operating lag amount etc. of crank motion thread-carrier drive division 62 of can cancelling out each other.
But even the Yarn reeling device 100 formed like this, the skew of the actual position Pr and target location Pi that also there is crank motion thread-carrier 61 as shown in Figure 3 becomes larger situation.
Herein, the major cause that the actual position Pr of crank motion thread-carrier 61 offsets from target location Pi is described.
As the first major cause, following reason can be enumerated: at bobbin B just from after halted state transfers to slew mode, because the rotative speed Bv of bobbin B is low, so be difficult to detect this rotative speed Bv exactly.Specifically, the cycle that rotative speed test section 73 is had to when the rotative speed Bv of bobbin B is low to obtain detection signal by pulse disc concavo-convex, the rotative speed of pulse disc lengthens detection signal time low.Its result, period is batched in the acceleration of package P, even if the rotative speed Bv of bobbin B increases, because the interval of the detection signal exported to unit controls portion 80 and crank motion control part 81 from rotative speed test section 73 is long, so unit controls portions 80 etc. cannot detect that the rotative speed Bv of bobbin B is in increase.That is, batch period in the acceleration of package P, there is the situation of rotative speed Bv lower than the rotative speed Bv of the bobbin B of reality of the bobbin B that unit controls portion 80 grade calculates.Therefore, crank motion control part 81, according to the correction front target location instruction Pt corresponding with the value of the rotative speed Bv being different from actual bobbin B, controls crank motion thread-carrier drive division 62.Its result, the situation that the actual position Pr that there is crank motion thread-carrier 61 offsets from target location Pi.
As the second major cause, the operating lag amount of this crank motion thread-carrier drive division 62 when supplying to crank motion thread-carrier drive division 62 electric power generated based on calculating result from crank motion control part 81 can be enumerated.Specifically, the electric power suitable with the correction front target location instruction Pt of the rotative speed Bv corresponding to bobbin B supplies to crank motion thread-carrier drive division 62 by crank motion control part 81.But if upgrade the control signal of the front target location instruction Pt of correction etc. and change traversing speed, then the operating lag amount of crank motion thread-carrier drive division 62 changes.Therefore, if traversing speed increases along with the increase of the rotative speed Bv of bobbin B, then the operating lag amount of crank motion thread-carrier drive division 62 increases, therefore, and the situation that the actual position Pr that there is crank motion thread-carrier 61 offsets from target location Pi.
Then, the reason that the Yarn reeling device 100 related to the first embodiment of the present invention batches in the acceleration of package P the skew that period can reduce between the actual position Pr of crank motion thread-carrier 61 and target location Pi is specifically described.
Fig. 4 A is the figure representing the correction of crank motion thread-carrier 61 front target location instruction Pt, revise the relation between rear target location instruction Ps and actual position Pr.Fig. 4 B is the figure of the rotative speed Bv representing bobbin B.Fig. 5 A is the figure of the relation between the actual position Pr of the crank motion thread-carrier 61 represented in Yarn reeling device 100 and target location Pi.Fig. 5 B is the figure of the rotative speed Bv representing bobbin B.
First, as the crank motion control part 81 of target location instruction determination section, the rotative speed Bv of bobbin B is obtained based on the detection signal from rotative speed test section 73.Specifically, crank motion control part 81 is configured to, and obtains the rotative speed Bv of bobbin B in each position control cycle (in figure Δ t) of crank motion thread-carrier 61.(with reference to Fig. 4 B).
Crank motion control part 81 predicts that the testing lag amount of the rotative speed Bv of bobbin B and the operating lag amount of crank motion thread-carrier drive division 62 decide target location correction Cp, and calculates the rear target location instruction Ps of correction based on this target location correction Cp.Crank motion control part 81 controlled crank motion thread-carrier drive division 62 based on the rear target location instruction Ps of correction in each position control cycle (in figure Δ t).
In addition, in Yarn reeling device 100 of the present embodiment, the testing lag amount of the rotative speed Bv of bobbin B reduces gradually along with the increase of the rotative speed Bv of bobbin B.This is because, as shown in Figure 3 A and Figure 3 B, grasp bobbin B in advance by crank motion control part 81 and shift from halted state towards slew mode and the time tr of rotative speed Bvr that arrives regulation, this testing lag amount can be predicted.Specifically, as shown in Figure 4 B, if the testing lag amount of the rotative speed Bv1 of bobbin B is defined as R1, the testing lag amount that later rotative speed detects period is defined as R2, R3, R4, then can represents in the following manner.
Testing lag amount R1 > testing lag amount R2 > testing lag amount R3 > testing lag amount R4
The testing lag amount R1 of the rotative speed Bv of bobbin B, R2, R3, R4, reduce gradually along with the increase of the rotative speed Bv of bobbin B.Crank motion control part 81 calculates instruction Ps in target location after the best correction of crank motion thread-carrier 61 by utilizing this characteristic, thus the control of the driving of the thread-carrier drive division 62 that can move back and forth.Its result, Yarn reeling device 100 of the present embodiment, can reduce the actual position Pr of crank motion thread-carrier 61 and the skew of target location Pi and prevent the generation of the cross winding disorder of package P.
In Yarn reeling device 100 of the present embodiment, the operating lag amount of crank motion thread-carrier drive division 62, increases gradually along with the increase of the rotative speed Bv of bobbin B.As shown in Figure 3 A and Figure 3 B, grasp bobbin B in advance by crank motion control part 81 and shift from halted state towards slew mode and the time tr of rotative speed Bvr that arrives regulation, this operating lag amount can be predicted.Specifically, as shown in Figure 4 A, if the operating lag amount of the crank motion thread-carrier drive division 62 corresponding with the rotative speed Bv1 of bobbin B is defined as r1, later operating lag amount is defined as r2, r3, r4, then can represents in the following manner.
Operating lag amount r1 < operating lag amount r2 < operating lag amount r3 < operating lag amount r4
The operating lag amount r1 of crank motion thread-carrier drive division 62, r2, r3, r4, increase gradually along with the increase of the rotative speed Bv of bobbin B.Crank motion control part 81 calculates instruction Ps in target location after the best correction of crank motion thread-carrier 61 by utilizing this characteristic, thus the control of the driving of the thread-carrier drive division 62 that can move back and forth.Specifically, crank motion control part 81 can to make the operating lag amount r1 of crank motion thread-carrier drive division 62, r2, r3, r4 become the constant driving of mode to this crank motion thread-carrier drive division 62 and control.Its result, Yarn reeling device 100 of the present embodiment, can reduce the actual position Pr of crank motion thread-carrier 61 and the skew of target location Pi and prevent the generation of the cross winding disorder of package P.
According to the above, as fig. 5 a and fig. 5b, in Yarn reeling device 100 of the present embodiment, even if the rotative speed Bv of bobbin B changes, also can prevent the actual position Pr of crank motion thread-carrier 61 from producing large skew from target location Pi.
In addition, Yarn reeling device 100 of the present embodiment, only when the rotative speed Bv of bobbin B increases, after calculating the correction of crank motion thread-carrier 61, instruction Ps in target location is to the control of the driving of the thread-carrier drive division 62 that moves back and forth.This is because, when the rotative speed Bv of bobbin B increases, the tendency that the skew of the actual position Pr and target location Pi that there is crank motion thread-carrier 61 increases.Thus, in Yarn reeling device 100 of the present embodiment, the actual position Pr of crank motion thread-carrier 61 and the skew of target location Pi can be reduced, the generation of the cross winding disorder of package P can be prevented.
Yarn reeling device 100 of the present embodiment, when the rotative speed Bv of bobbin B is constant or reduce, do not calculate instruction Ps in target location after the correction of crank motion thread-carrier 61, but to move back and forth the control of driving of thread-carrier drive division 62 based on revising front target location instruction Pt.This is because, when the rotative speed Bv of bobbin B is constant or reduce, the tendency that the skew of the actual position Pr and target location Pi that there is crank motion thread-carrier 61 does not increase.Thereby, it is possible to simplify the control structure of Yarn reeling device 100.
Then, in the Yarn reeling device 200 that the second embodiment of the present invention relates to, the reason of the skew of the actual position Pr and target location Pi that can reduce crank motion thread-carrier 61 is specifically described.The difference of the Yarn reeling device 100 that Yarn reeling device 200 of the present embodiment and the first embodiment relate to is, be not instruction crank motion thread-carrier 61 through time displacement but instruction traversing speed.But the structure identical to the Yarn reeling device 100 with above-mentioned marks identical symbol, is described around different parts.
Fig. 6 A is target velocity instruction Vt before the correction representing crank motion thread-carrier 61, revise after the figure of relation between target velocity instruction Vs and actual speed Vr.Fig. 6 B is the figure of the rotative speed Bv representing bobbin B.Fig. 7 A is the figure of the relation between the actual position Pr of the crank motion thread-carrier 61 represented in Yarn reeling device 200 and target location Pi.Fig. 7 B is the figure of the rotative speed Bv representing bobbin B.In addition, the front target location instruction Pt of correction is described in fig. 6 in order to reference and instruction Ps in target location after revising.
First, as the crank motion control part 81 of target velocity instruction determination section, the rotative speed Bv of bobbin B is obtained based on the detection signal from rotative speed test section 73.Specifically, crank motion control part 81 is configured to, and obtains the rotative speed Bv of bobbin B at each velocity control period (in figure Δ t) of crank motion thread-carrier 61.(with reference to Fig. 6 B).
Crank motion control part 81 predicts that the testing lag amount of the rotative speed Bv of bobbin B and the operating lag amount of crank motion thread-carrier drive division 62 decide target velocity correction Cv, and calculates the rear target velocity instruction Vs of correction based on this target velocity correction Cv.Crank motion control part 81 target velocity instruction Vs after each velocity control period (in figure Δ t) is based on correction controls crank motion thread-carrier drive division 62.
In addition, in Yarn reeling device 200 of the present embodiment, the testing lag amount of the rotative speed Bv of bobbin B reduces gradually along with the increase of the rotative speed Bv of bobbin B.As shown in Figure 3 A and Figure 3 B, grasp bobbin B in advance by crank motion control part 81 and shift from halted state towards slew mode and the time tr of rotative speed Bvr that arrives regulation, this testing lag amount can be predicted.Specifically, as shown in Figure 6B, if the testing lag amount of the rotative speed Bv1 of bobbin B is defined as R1, later testing lag amount is defined as R2, R3, R4, then can represents in the following manner.
Testing lag amount R1 > testing lag amount R2 > testing lag amount R3 > testing lag amount R4
The testing lag amount R1 of the rotative speed Bv of bobbin B, R2, R3, R4, reduce gradually along with the increase of the rotative speed Bv of bobbin B.Crank motion control part 81 calculates target velocity instruction Vs after the best correction of crank motion thread-carrier 61 by utilizing this characteristic, thus the control of the driving of the thread-carrier drive division 62 that can move back and forth.Its result, Yarn reeling device 200 of the present embodiment, can reduce the actual position Pr of crank motion thread-carrier 61 and the skew of target location Pi and prevent the generation of the cross winding disorder of package P.
In Yarn reeling device 200 of the present embodiment, the operating lag amount of crank motion thread-carrier drive division 62 increases gradually along with the increase of the rotative speed Bv of bobbin B.As shown in Figure 3 A and Figure 3 B, grasp bobbin B in advance by crank motion control part 81 and shift from halted state towards slew mode and the time tr of rotative speed Bvr that arrives regulation, this operating lag amount can be predicted.Specifically, as shown in Figure 6A, if the operating lag amount of the crank motion thread-carrier drive division 62 corresponding with the rotative speed Bv1 of bobbin B is defined as r1, later operating lag amount is defined as r2, r3, r4, then can represents in the following manner.
Operating lag amount r1 < operating lag amount r2 < operating lag amount r3 < operating lag amount r4
The operating lag amount r1 of crank motion thread-carrier drive division 62, r2, r3, r4, increase gradually along with the increase of the rotative speed Bv of bobbin B.Crank motion control part 81 calculates target velocity instruction Vs after the best correction of crank motion thread-carrier 61 by utilizing this characteristic, thus the control of the driving of the thread-carrier drive division 62 that can move back and forth.Specifically, can to make the operating lag amount r1 of crank motion thread-carrier drive division 62, r2, r3, r4 become the constant driving of mode to this crank motion thread-carrier drive division 62 and control.Its result, Yarn reeling device 200 of the present embodiment, can reduce the actual position Pr of crank motion thread-carrier 61 and the skew of target location Pi and prevent the generation of the cross winding disorder of package P.
According to the above, as shown in figures 7 a and 7b, in Yarn reeling device 200 of the present embodiment, even if the rotative speed Bv of bobbin B changes, also can prevent the actual position Pr of crank motion thread-carrier 61 from producing large skew from target location Pi.
In addition, Yarn reeling device 200 of the present embodiment, only when the rotative speed Bv of bobbin B increases, after calculating the correction of crank motion thread-carrier 61, target velocity instruction Vs is to the control of the driving of the thread-carrier drive division 62 that moves back and forth.This is because, when the rotative speed Bv of bobbin B increases, the tendency that the skew of the actual position Pr and target location Pi that there is crank motion thread-carrier 61 increases.Thus, in Yarn reeling device 200 of the present embodiment, the actual position Pr of crank motion thread-carrier 61 and the skew of target location Pi can be reduced and prevent the generation of the cross winding disorder of package P.
