DETAILED DESCRIPTION OF THE PREFERRED
With reference to the accompanying drawings embodiments of the invention are described, Fig. 1 is the calcspar according to motor control assembly in the one embodiment of the invention weaving loom.
Weaving loom shown in Fig. 1 is the friction-type Yarn winder and the godet device that is arranged at this Yarn winder upstream side that are used for the winding synthetic threads yarn.This friction-type Yarn winder is by force to drive a friction roller of describing later 127 and drive and rotate a bobbin group that is positioned on the bobbin retainer 123,124.With reference to Fig. 1, the synthetic filaments reel for yarn system for winding with friction-type Yarn winder and godet device is described.
Synthetic filaments reel for yarn system for winding is the combination of godet device 101 and Yarn winder 102.Godet device 101 comprises first godet 111 and second godet 112 that is driven by synchronous machine M2 that are driven by synchronous machine M1.First godet 111 and second godet 112 are provided with in proper order along people's yarn throughput direction.Go out a plurality of synthetic filaments yarns (yarn only is shown Fig. 1) from a spinning-drawing machine (not shown) melt spinning.These yarns form one group of yarns Y of arranging from left to right, and enter in first godet 111.These yarns Y are sent to yarns Y around first godet, 111 coiling several times with actuating force.This group yarns Y of leaving first godet 111 enters in second godet 112.Yarns Y is sent to yarns Y around second godet, 112 coiling several times with actuating force.Leave the axis direction expansion of this group yarns Y of second godet 112, and be wound in each package by Yarn winder 102 at godet.
On bobbin retainer 123,124, be respectively equipped with four to six bobbin B (for ease of diagram, a bobbin B only being shown among Fig. 1).One in the bobbin retainer 123,124 is arranged on a winding position (a), and another in the bobbin retainer 123,124 is arranged on a position of readiness (b).Reel for yarn is on the bobbin B that is positioned at winding position (a).Each when bobbin B becomes full bobbin, capstan head disk 122 Rotate 180 degree, yarn begin to be wound on the ceases to be busy axle B who newly is positioned on the winding position (a).
Below in above-mentioned Yarn winder 102, making brief description from the motion of full bobbin B yarn when a ceases to be busy axle B transmits yarn.When transmitting yarn, the bobbin that will contact with friction roller 127 switches to another bobbin from a bobbin.
When the bobbin B that is positioned at winding position (a) became full bobbin, capstan head disk 122 Rotate 180 degree, and the position of switching bobbin retainer 123,124 made full bobbin B be positioned at position of readiness (b) and ceases to be busy axle B is positioned at winding position (a).But when each bobbin B laid respectively at a reposition, the yarn of being supplied still connected with the full bobbin B that is positioned at position of readiness (b).Yarn is caught by the slit 117 of ceases to be busy axle B.End transmits yarn from full bobbin B to ceases to be busy axle B.In other words, at yarn because the co-operation of top yarn transfer device 118 and bottom yarn conveyer 129 and when being caught by slit 117, the yarn that connects with full bobbin B is disconnected by the yarn tension that the rotation owing to ceases to be busy axle B produces, and yarn newly is wound up on the ceases to be busy axle B.Fig. 1 illustrates at once a state before yarn is sent to the ceases to be busy axle from full bobbin.
In above-mentioned yarn transfer operation process, because full bobbin B leaves from the state of expiring bobbin B contact friction roller 127, friction roller 127 has the rotation of load ground.Simultaneously, when ceases to be busy axle B contact friction roller 127, on friction roller 127, apply a load.As mentioned above, owing in yarn transfer operation process (bobbin switch step) load fluctuation is arranged, high pulling torque becomes necessary.Therefore the boost phase that begins to rotate to friction roller 127 is similar with the decelerating phase that friction roller 127 stops the rotation, the bobbin switch step, just the bobbin that will contact with friction roller 127 switches to time period of another bobbin from a bobbin, thinks the unsettled operational phase equally.
Synchronous machine M1, M2, M3 drive the roller 111,112,127 of coiling and threading yarn respectively.
Described below bobbin switch step or when Yarn winder began to operate, induction machine M4, M5 drove 123,124 1 periods short time of bobbin retainer respectively.
The frequency and the voltage of each driver (phase convertor) DR1, DR2, DR3 conversion AC power.Each driver (phase convertor) DR1, DR2, DR3 comprise a control unit (V-F figure modifier) 21, and this control unit output makes output voltage and output frequency become the setting of figure up to specification.According to the output from control unit 21, output voltage converts an assigned voltage to, and output frequency is controlled so as to an assigned frequency.
According to from the figure selecting of main control unit 2 instruction f2, control unit 21 selects to be stored in the V-F figure 1,2 among the memory cell 21a.According to speed command f1, on selected V-F circular foundation, form a signal then according to output frequency and output voltage from main control unit 2.Then from the output frequency of a regulation of driver (phase convertor) output and the output voltage of a regulation.As mentioned above, control unit 21 is as the modifier that changes output voltage-output frequency figure (relationship expression of output voltage and output frequency).V-F figure modifier 21 is not arranged among driver (phase convertor) DR4, the DR5, but a fixing V-F figure is set in driver DR4, DR5.
Driver (phase convertor) DR1, DR2, DR3, DR4, DR5 that main control unit 2 will be used for synchronous machine M1, M2, M3 and induction machine M4, M5 integrate, and control the driving of whole synthetic filaments reel for yarn system for winding.For integrated control, for with predetermined circumference speed and moment of torsion rotation roller 111,112,127, main control unit 2 is determined at mode of operation on the basis of device 2a speed command f1 and figure selecting instruction f2 to be outputed to each driver (phase convertor) DR1, DR2, the DR3 with V-F figure modifier 21.The speed command f1 and the figure selecting instruction f2 that output to each driver DR1, DR2, DR3 are independent instructions for each driver.Main control unit 2 is also to the independent speed command f1 of driver DR4, DR5 output that does not have V-F figure modifier.
Because the whole synthetic filaments reel for yarn system for winding of main control unit 2 controls, mode of operation are determined device 2a and are determined that the mode of operation of Yarn winder and godet device is stable operation stage or unstable operational phase.Particularly, mode of operation determines that device 2a is according to determining from the signal of each switch or each transducer.Mode of operation when needing high pulling torque is the unstable operational phase, and other mode of operation is the stable operation stage.All need high pulling torque owing to be used to start the decelerating phase that the boost phase and being used to of the operation of Yarn winder and godet stops the operation of Yarn winder and godet, it is the unstable operational phase.Operational phase when in Yarn winder, stably reeling and by the godet device stably the operational phase of delivered yarn is the stable operation stage.The stable operation stage is the long time period than unstable big hundred times of operational phase.
As shown in Figure 3, the boost phase that is used to start is to begin along with the operation of starting Yarn winder, finishes through an official hour section t1 afterwards along with rotation quantity arrives a specified quantity.Initial threading operation is carried out at boost phase, up to process official hour section t1.Threading operation is such operation, with the synthetic filaments yarn through on each roller 111,112,127, the synthetic filaments yarn that is transferred with an air-breathing rifle attraction simultaneously.Mode of operation determines that device 2a determines to be in the unstable operational phase at boost phase.Then, mode of operation determines that control unit 21 outputs of device 2a each in driver DR1 to DR3 are used to select the instruction f2 of high pulling torque V-F figure 1.
When the threading operation finished for each roller 111,112,127, operation advanced to the operating winding stage, determines it is in the stable operation stage.Determine device 2a when mode of operation and determine to be in stable operation during the stage that control unit 21 outputs of each in each driver DR1 to DR3 are used to select the instruction f2 of little moment of torsion V-F figure 2.
Bobbin shown in Fig. 3 switches, and to be the bobbin that will contact with friction roller 123 switch to time period of another bobbin from a bobbin, in this stage (bobbin switch step), produces load fluctuation in friction roller 123.Therefore under the situation of friction-driven type Yarn winder, the boost phase during except starting and the decelerating phase when stopping, the time period when bobbin is automaticallyed switch is the unstable operational phase equally.Main control unit 2 grasps bobbin switch step (being used to transmit the yarn transfer phase of yarn).Mode of operation determines that device 2a determines to be in the unstable operational phase for the motor M 3 of friction roller 123 at the yarn transfer phase.Then, mode of operation determines that device 2a is used to select the instruction f2 of high pulling torque V-F figure 1 to control unit 21 outputs of the driver DR3 of the motor M 3 that is used for friction roller 123.At the yarn transfer phase owing in godet 111,112, do not produce big load fluctuation, mode of operation determine device 2a uncertain be to be in the unstable operational phase for the motor M 1 of godet 111 and the motor M 2 of godet 112.Therefore be not used to select the instruction of V-F figure 1 to control unit 21 outputs of driver DR1, the DR2 of the motor M 1 that is used for godet 111,112, M2.
Below with reference to Fig. 1 to Fig. 3 the operation of motor control assembly 1 is described.
When the operation starting of Yarn winder, godet 111,112 and friction roller 127 accelerate to a peripheral speed that satisfies the synthetic filaments yarn speed of service.At this moment, the mode of operation of main control unit 2 determines that device 2a determines that it is the unstable mode of operation of boost phase.Then, mode of operation determines that device 2a is used for selecting the instruction f2 of Fig. 2 V-F figure 1 respectively to control unit 21 outputs of each driver DR1, DR2, DR3.Therefore, each synchronous machine M1, M2, M3 quicken each roller 111,112,127 with high moment of torsion respectively, and the roller 111,112,127 with big inertia can start in the official hour section.After each roller 111,112,127 arrived a regulation rotating speed, up to having passed through official hour section t1 by timer settings etc., mode of operation determined that device 2a determines to be in unstable mode of operation, and selects the V-F figure 1 among Fig. 2.
Finish initial threading operation at boost phase.In addition, at short boost phase, in order to reduce the vibrations when the bobbin retainer that is positioned at winding position (a) contacts with friction roller, drive the motor of the bobbin retainer that is positioned at winding position (a), and after being positioned at the bobbin retainer contact friction roller of winding position (a), stop.
Behind the threading EO, process advances to operating winding, and wherein the synthetic filaments yarn of threading on each roller 111,112,127 moves along each roller with the constant speed of a regulation.Then, the mode of operation of main control unit 2 determines that device 2a determines to be in the steady state operation of winding portion.Then, mode of operation determines that device 2a is used for selecting the instruction f2 of Fig. 2 V-F figure 2 to control unit 21 outputs of each driver DR1, DR2, DR3.Therefore, each synchronous machine M1, M2, M3 are with each roller 111,112,127 of little torque drive, with a predetermined circumference speed drive roller 111,112,127.In winding process, owing to selected to have the V-F figure of little moment of torsion, the efficient of synchronous machine M1, M2, M3 is improved.As a result, cpable of lowering power consumption can suppress that the motor feels hot, and can prolong the service time of bearing.Because the output current of each driver (phase convertor) DR1, DR2, DR3 reduces, also can prolong the duration of driver.Because winding portion continues long time period, can save power greatly, and can prolong the duration of bearing and driver greatly.
When from full bobbin when the ceases to be busy axle transmits yarn automatically, the mode of operation of main control unit 2 determines that it is the unstable mode of operation of yarn transfer phase that device 2a determines.Then, mode of operation determines that device 2a is used for selecting the instruction f2 of Fig. 2 V-F figure 1 to control unit 21 outputs of the driver DR3 of friction roller 127.Therefore, synchronous machine M3 keeps synchronous regime with high torque drive friction roller 127 when synchronous machine M3 is driven, and the bobbin that will contact with friction roller 127 switches to another bobbin from a bobbin simultaneously.After yarn transfer phase t3 finished, the mode of operation of main control unit 2 determined that device 2a determines to be in the steady state operation of winding portion.Then, mode of operation determines that device 2a is used for selecting the instruction f2 of Fig. 2 V-F figure 2 to control unit 21 outputs of driver DR3.Therefore high efficiency drive synchronous machine M3 once more.
In addition, in above-mentioned yarn transfer operation process, produce fluctuation in yarn tension, this fluctuation is sent to the godet 111,112 that is positioned at upstream side.But when the synthetic filaments yarn is that the fluctuation of yarn tension is less when being used for the common yarn of clothes.Therefore for godet 111,112, even also determine to be in steady state operation at above-mentioned yarn transfer phase.
When promptly stopping or normally stopping the operation of Yarn winder, the mode of operation of main control unit 2 determines that device 2a determines to be in unstable mode of operation, and is used for selecting the instruction f2 of Fig. 2 V-F figure 2 to control unit 21 outputs of each driver DR1, DR2, DR3.Therefore, each synchronous machine M1, M2, M3 quicken each roller 111,112,127 with high moment of torsion, and can be in an official hour section rotation of stop roller 111,112,127.
