Description

Button Driven Textile Machines {INDIVIDUAL-SPINDLE-DRIVE TYPE TEXTILE MACHINE}

The present invention relates to a button-driven textile machine configured to be provided with a plurality of additional side by side, to install a spindle drive motor in each weight, and to drive-control the plurality of drive motors by the rotation speed control device. .

Conventional multi-twist machines include a plurality of multi-twisting units having a spindle device 301a and a winding-up device 301b, as shown in FIG. 13, and the multi-twisting unit includes a winding drum 306 and The drive mechanism 310 which drives the traverse guide 307 and the spindle 303 is provided. The spindle device 301a twists the thread by transmitting the driving force of the drive motor 313 to the spindle 303 by the belt 304. In addition, the winding device 301b is wound around the winding package 105 while traversing the yarn twisted by the spindle device 301a by the traverse guide 307 via the feed roller 308.

The drive mechanism 310 mainly includes a drive motor 313, a plurality of pulleys 311, 312, 315, 316, 317, and 319, and belts 304 and 318, and a winding drum 306 and traverse. The guide 307 and the spindle 303 are driven by one drive motor 313. In addition, the spindle 303 has an output of the driving motor 313 via the output shaft 314, the third pulley 315, the belt 318, the fifth pulley 317, and the first pulley 311. And to drive. In addition, the winding drum 306, the output of the drive motor 313 is the output shaft 314, the fourth pulley 316, belt 320, the sixth pulley 319, the transmission belt device 350, the reduction box ( 323 and the belt 330 are transmitted and driven. In addition, the traverse guide 307 is rotated by the support shaft 326 via the belt 334 to the grooved drum 337, the cam shoe 339 is grooved by the rotation of the grooved drum 337. By moving along 338, the reciprocating motion is performed.

However, when the spindle apparatus 301a and the winding apparatus 301b are driven by one drive motor 313 as in the conventional multi-twist twister, a plurality of pulleys are rotated by the belts 304 and 320, so that the mechanical In addition to high losses and excessive power consumption, each spindle may not be maintained at a precisely predetermined number of revolutions. Therefore, the spindle drive system and the winding drum drive system are driven by separate motors, and each spindle unit has a spindle drive motor. Button-driven multi-burst machine has been developed to install and drive independently. However, in the multiple twister for driving the spindle drive system and the winding drum drive system by separate motors, when each motor stops (braking each motor) during a power failure, the moment of inertia of the spindle drive system is compared with that of the winding drive system. Because of their very large size, the motor of the spindle drive system inertia rotates for a while even after the winding drum drive system stops, resulting in a new problem that results in a tight twist and break of the twist.

Therefore, at the time of power failure, a multi-twist machine has been developed that can prevent the break of twist by stopping and decelerating while synchronizing the spindle drive motor and the drum drive system motor.

However, since the multi-burst machine drives the winding drum and the traverse device by separate motors, it is necessary to completely synchronize the winding drum, the traverse device, and the spindle drive system in order to prevent the traverse deviation and winding. There is a problem that requires a high degree of control.

Therefore, the present invention has been made in view of the above problems, and a first object is to provide a button-driven fiber machine capable of decelerating and stopping while synchronizing the spindle drive system and the drum drive motor by simple control at the time of power failure.

In addition, since the button drive multiple twister is provided with a spindle drive motor on each spindle, when a plurality of winding units are arranged, there is a problem that a voltage drop of the power supply bus may occur. That is, the conventional button-driven fiber machine which has a drive motor for every spindle for twisting thread, for example, may generate a voltage drop, and cannot perform rotation drive of each spindle stably, There was a problem that there is a case where the imparted twist is not stable.

Therefore, the present invention has been made in view of the above problems, and a second object is to provide a button driven fiber machine which can prevent voltage drops even when a plurality of winding units are arranged in an arrangement.

In order to achieve the first object, the invention as set forth in claim 1 is a button-driven textile machine which drives a plurality of spindle drive motors and a plurality of winding drum drive motors in common for each spindle by a rotation speed control device, When a voltage equal to or more than a predetermined voltage drops, power failure detection means for detecting power failure, stop command means for outputting a stop command to each rotation speed control device at the time of power failure detection, and for each of the motors at a preset stop time based on the stop command. And stop means for executing feedback control to stop.

Thus, after detecting the power failure due to a decrease in the power supply voltage by a predetermined time or more, the feedback control is executed while detecting the rotation speed of each motor independently for each rotation speed control device until each motor stops, The number of rotational speed signals and the external rotational speed command means to each rotational speed control device can be made unnecessary between each rotational speed control device, and the speed reduction can be stopped while synchronizing each motor by simple control.

And a central control unit which transmits a stop command all at once via the control signal line to the apparatus.

As a result, when the power failure is detected, the respective speed controllers decelerate and stop at the same stop time at the same stop time by receiving the stop command from the central controller, so that the central controller only transmits a stop command to the respective speed controllers. The motor can be decelerated and stopped while synchronizing each motor by simple control. In addition, a battery, a battery, or the like for controlling the central control device can be made unnecessary during the electrostatic treatment.

Auxiliary power supply including a DC power supply means for arranging a common control power supply line in a plurality of speed control devices belonging to the rotation speed control device group, and for forming a control system voltage on the control power supply line from the voltage on the DC bus. An apparatus is provided.

Thereby, in the deceleration period after a power failure detection, the regenerative power from each spindle drive motor obtained through the power supply power line can be converted into a suitable voltage and used as the control system voltage of each rotation speed control device group. In addition, since the DC transformer means is formed for each rotation speed control device group, the wiring can be simplified and the voltage drop can be prevented, and the deceleration control of each rotation speed control device can be surely performed.

In addition to the structure of the invention of Claim 5, invention of Claim 6 has the central control apparatus with a communication function, and the repeater which integrates each rotation speed control apparatus for the said drive motors for every said said units, The central control unit and each of the rotational speed control units are connected by a communication line via the repeater.

Thereby, the parameter setting regarding control of each motor can be performed collectively from a central control apparatus with respect to many rotation speed control apparatuses. Even if the number of weights installed side by side is increased, motor control by each rotation speed control device can be reliably performed.

In addition to the configuration of the invention according to claim 5 or 6, the invention described in claim 7 makes each unit equal to the number of the rotation speed control device connected to one DC transformer means and one repeater. It is done.

As shown in FIG. 3, the control system 7 also serves as an electrostatic treatment device 7 in addition to the control of the spindle device 2 and the winding device 3. The electrostatic processor 7 has a main body control device 48 and a plurality of unit control units 9 for controlling the respective spindle devices 2, and when the voltage of the AC power supply 36 decreases for a predetermined time, The electrostatic processing is performed. The main body control device 48 includes a converter 41 for converting the voltage of the AC power supply 36, a host CPU 35 (central control device) constituting the stop command means, and an electrostatic detector constituting the power failure detection means. (34) and an inverter 42 constituting a stop means for the winding drum drive motor, and instructing the unit control unit 9 constituting the stop means and the inverter 42 for the take-up drum drive motor at the same time. To output

The blackout detector 34 is connected to the host CPU 35, and when it detects that the voltage of the AC power supply 36 has fallen for a predetermined time or more, it transmits a blackout detection signal to the host CPU 35. When the host CPU 35 receives the power failure detection signal, the host CPU 35 simultaneously transmits a stop command to each unit control unit 9 and the winding drum drive motor inverter 42 directly via the control signal line 53.

The host CPU 35 is connected to the DC / DC converter 41b, and the DC / DC converter 41b is configured to convert the DC voltage into a voltage of 24V for use as the control system voltage of the host CPU 35. have.

Each unit control unit 9 has 32 inverters 45 for the spindle drive motor, one repeater 44, and one auxiliary power supply 43, and a communication line ( It is connected in parallel via 46). 32 inverters 45 are connected to the repeater 44 in parallel via the communication line 51.

In addition, the repeater 44 receives the rotation speed of the spindle drive motor 6 and the command value for the spindle drive motor 6 output from each inverter 45, and receives the host CPU 35 via the communication line 46. Command) is sent.

The 32 inverters 45 constituting each unit control unit 9 are connected in series via a control power supply line 49, a control signal line 50, and a communication line 51. A relay connector board 52 is interposed between the 32 inverter groups and the auxiliary power supply 43, and the control power supply line 49 passes from the auxiliary power supply 43 through the relay connector board 52. And a repeater 44. Similarly to the DC bus 47, the control signal line 50 arranged along the base from the host CPU 35 is connected to the inverter group and the repeater 44 via the relay connector board 52. have. In addition, two spindle drive motors 2 are connected to each inverter 45. Each inverter 45 has a regenerative circuit, and outputs the regenerative electric power generated by rapidly decelerating the spindle drive motor 6 at the time of power failure to the DC bus 47 which is a power supply line for power. Each inverter 45 has a predetermined stop time set in advance.

The regenerative power is generated because the inertia (moment of inertia) is large at the time of power failure and the spindle drive motor 6 is rapidly decelerated, so that the regenerative power is operated as a so-called generator.

One auxiliary power supply 43 is provided for each unit control unit 9 and is connected in parallel via a DC bus 47. In addition, the auxiliary power supply 43 has a DC transformer 43a, which is required to control the spindle drive motor 6 with the DC voltage supplied via the DC bus 47 during normal operation and power failure. It converts into control system voltage of and supplies it to inverter group. The control inverter voltage of 24 V is supplied to each of the inverters 45 via the control power supply line 49 to the 32 inverters 45.

In addition, the inverter 42 for the winding drum drive motor receives the stop command via the control signal line 53, and then is driven by the DC voltage of the DC bus 47 secured by the regenerative power from the motor 6. The winding drum drive motor 4 is feedback-controlled independently, and the winding drum drive motor 4 is decelerated and stopped at a predetermined predetermined stop time. That is, each inverter 42, 45 is made to decelerate and stop each motor 4, 6 separately, respectively. In addition, the inverter 42 for the winding drum drive motor has a direct current transformer (not shown) for forming a control system voltage therein.

As described above, in the electrostatic treatment device 7 according to the present embodiment, the main body control device 48 takes in the rotational speed of the spindle drive motor 6 and the rotational speed of the winding drum drive motor 4 so that both motors ( Rather than controlling 4, 6 to synchronize, it is to control each motor 4, 6 separately. Therefore, the number of rotations of the spindle drive motor 6 and the number of revolutions of the winding drum drive motor 4 is not required, the wiring can be simplified, and high level control is not required.

In the above configuration, the operation of the button-type multiple twister 1 will be described with reference to the drawings. As shown in Fig. 1, when electric power is supplied from the AC power supply 36 to the inverter 45 for the spindle drive motor via the converter 41 and the DC bus 47, the spindle drive motor 6 is driven. Each rotating disk 33 rotates at the same rotational speed as each spindle drive motor 6. When each rotating disk 33 is rotated, the thread Y released from the processing chamber package 8 enters the tension device 32, is twisted once while applying tension, and twisted once again to the balloon guide 37. Swell.

On the other hand, when electric power is supplied to the inverter 42 for the winding drum drive motor via the DC bus 47, the winding drum drive motor 4 is driven, and the output thereof is each pulley 10, 12, 16, 19, 22, 24, belts 13, 20, 25, reducer 11, continuously variable transmission 17 and cam box 27 are transmitted to each support shaft 18, 23 and reciprocating rod 18, The winding drum 21 and the feed roller 26 of each weight rotate, and the traverse guide 29 of each weight reciprocates.

And when the winding drum 21 and the feed roller 26 of each weight rotate, and the traverse guide 29 of each weight reciprocates, the thread Y twisted twice by the spindle apparatus 2 While being traversed by the traverse guide 29, it is wound up by the winding package P. FIG. In traverse, the traverse angle is corrected by the continuously variable transmission 17.

In this manner, while the seal Y is wound in the winding package P, as shown in FIG. 4, when the electrostatic detector 34 detects a drop in the power supply voltage (S1, YES), the host CPU 35 Determines whether it has been lowered for a predetermined period (for example, 1 msec) or more (S2). In the case of less than a predetermined period (for example, 1 msec) (S2, NO), the power failure time is short, so that each device 2, 3 executes a predetermined return operation without any problem in the operation of the multi-burst machine 1. (S3), normal operation is continued.

On the other hand, in S2, when the predetermined period (for example, 1 msec) or more (S2, YES), the stop command is passed through the control signal line 53 by the host CPU 35 via the winding drum drive motor inverter 42 and It is transmitted to the relay connector board 52 formed in each unit control part 9 simultaneously. The stop command is transmitted from the relay connector boards 52 to the respective inverters 45 through the control signal line 50 at once (S4). After the inverters 42 and 45 receive the stop command, the power supply from the AC power supply 36 to the spindle drive motor 6 and the winding drum drive motor 4 is stopped.

Since the inertia is large even when the power supply is stopped, the spindle drive motor 6 is decelerated rapidly to stop at the predetermined stop time, thereby operating as a generator, thereby generating regenerative power. This regenerative power is output from the regenerative circuit of each inverter 45 to the DC bus 47 which is a power supply line, and a part of the regenerative power is driven by the spindle via the auxiliary power supply 43 and the control power supply line 49. It is supplied to each inverter 45 as a control system voltage of the motor 6. The other regenerative power is supplied as a control system voltage from a direct current bus 47, which is a power supply line, to a direct current transformer (not shown) inside the inverter 42 for the winding drum drive motor.

Thereby, each inverter 45 is built in the stator part arranged around the rotor, and based on the rotation speed detected by the built-in hall sensor for detecting the rotational position of the rotor, the inverter 45 is connected to the spindle drive motor 6. Respectively independently decelerate and stop the spindle drive motor 6 at a predetermined stop time. In addition, the inverter 42 for the winding drum drive motor takes the rotational speed of the winding drum drive motor 4 from the pulse generator 30 provided separately from the winding drum drive motor 4, While independently controlling feedback, the winding drum drive motor 4 is decelerated and stopped at a predetermined stop time (S5). Then, each spindle drive motor 6 and the winding drum drive motor 4 are decelerated while being synchronized, and stop at the same time after a predetermined stop time has elapsed (S6).

In addition, the control power supply line 49 of the multiple twister 1 which concerns on a present Example is for supplying the control system voltage 24V for controlling the spindle drive motor 6 to each inverter 45. As shown in FIG. In addition, the control signal lines 50 and 53 are for transmitting a stop command to all the inverters 42 and 45 at the time of a power failure detection, and are for transmitting the simultaneous start or simultaneous stop signal of normal expectation. In addition, the communication lines 46 and 51 monitor the rotation speed of each motor 6, the command value for each motor 6, etc. by the host CPU 35, or each inverter 42, from the host CPU 35. 45) is for setting parameters for controlling.

Further, in the multiple twister 1 according to the present embodiment, the winding drum 21 and the traverse mechanisms 28 and 29 are mechanically connected by the cam box 27, and they have a common winding drum drive motor 4. It is supposed to be driven by.

A second embodiment of a button driven fiber machine according to the present invention will be described below with reference to Figs. As shown in Fig. 5, the button-driven multi-twist twisting machine 101 is configured by arranging thread winding units U of 80 to 308 weights. The one thread winding unit U has the spindle apparatus 102 and the winding apparatus 103 provided in succession, and wound up the thread of the single feeding chamber package 108 to the winding package P. As shown in FIG.

The spindle device 102 has a supply chamber package 108, a stop plate 131, a tension device 132, a rotating disk 133, and a spindle drive motor (drive motor) 106. The seal Y is twisted by the drive motor 106. The DC brushless motor BLM is used for this spindle drive motor 106, and the rotating disk 133 is provided in the output shaft. In addition, the rotating disk 133 is provided with a stop plate 131, and one feeding chamber package 108 can be mounted on the stop plate 131. Moreover, the tension device 132 is provided in the upper part of the processing chamber package 108, and the tension apparatus 132 is provided so that the predetermined tension may be given to the thread Y loosened from the processing chamber package 108. FIG.

As a result, the spindle device 102 rotates the rotating disk 133 at high speed by the spindle drive motor 106 while applying tension to the tension device 132 by putting the thread Y released from the processing chamber package 108 into the tension device 132.

As shown in Figs. 9 and 11, the inverter 244 for the spindle drive motor has a start control unit 244a and a release control unit 244b, and the start and solenoid valves of the spindle drive motor 206 [ SV 208 is controlled to open and close. When the spindle control motor 244a drives the spindle drive motors 206 together, the spindle control motor 206 controls each spindle drive motor 206 so as to smoothly start the vehicle in about 15 seconds to 20 seconds while the other weight (spindle) is being wound up. In the case of driving any of the spindle drive motors 206, the spindle drive motor 206 is controlled to start rapidly in about 10 seconds.

Further, when the release control unit 224b drives any spindle drive motor 206 during winding of another weight (spindle), after a predetermined time (2 seconds) has elapsed after starting any spindle drive motor 206. The solenoid valve SV 248 is controlled to release the winding package brake 230.

Moreover, when the start switch 250 which comprises an operation means is connected to each said inverter 244 for spindle drive, and drives the arbitrary spindle drive motor 206 during the winding of another weight (spindle), When the start switch 250 is turned ON, the spindle drive motor 206 is started.

In the above configuration, the operation of the button-driven multi-twist machine 201 will be described with reference to the drawings. 9 and 11, a DC voltage of 24 V is applied to each inverter 244 from the AC power supply 234 via the converter 235, the DC bus 247, and the DC transformer 243 for the spindle device. Supplied. In addition, a start command is transmitted from the host CPU 236 via the control signal line 257 to each relay connector board 256, and the spindle drive from each relay connector board 256 via the control signal line 258. It is transmitted to the inverter 244 for motors simultaneously. Each spindle drive motor 206 starts driving at the same time based on the command of the start control part 244a of each inverter 244, and each rotating disk 233 also rotates with the same rotation speed as each spindle drive motor 206. Initiate. Each spindle manual motor 206 then reaches a predetermined rotational speed about 15 seconds from the start of rotation. When each of the rotating disks 233 rotates, the thread Y released from the processing chamber package 208 enters the tensioning device 232, is twisted once while applying tension, and twisted once again to give a balloon guide ( Up to 237).

On the other hand, a DC voltage of 290 V is supplied from the AC power supply 234 to the inverter 241 for the winding drum drive motor via the converter 235 and the DC bus line 247, and a start command is supplied to the host CPU 236. From the control signal line 257 to the inverter 241. The winding drum drive motor 204 is driven based on the command of the inverter 241, the output of each of the pulleys 210, 212, 216, 219, 222, 224, belts 211, 214, 220, 225, It is transmitted to each of the support shafts 218 and 223 and the reciprocating rod 228 via the reducer 217, the cam box 227, and the winding drum 221 and the feed roller 226 of each weight rotate, The traverse guide 229 of each weight reciprocates.

And when the winding drum 221 of each weight and the feed roller 226 rotate, and the traverse guide 229 of each weight reciprocates, the thread Y twisted twice by the spindle apparatus 202 is carried out. Is wound by the traverse guide 229 and is wound up by the winding package P. As shown in FIG. In traverse, the traverse angle is corrected by the reducer 217.

As described above, when thread cutting occurs while the yarn Y is wound on the winding package P, a thread cutting sensor (not shown) transmits a motor stop signal to the inverter 244 for the spindle drive motor. When the inverter 244 for the spindle drive motor receives the motor stop signal, it stops the spindle drive motor 206 and transmits an opening / closing signal to the solenoid valve SV 248. The solenoid valve SV 248 opens the valve to send air to the cylinder 253 and to rotate the link arm 252. Thereby, since the link arm 252 contacts between the winding package P and the winding drum 221, the winding package P will be in a brake state. At this time, the winding drum 221 which is common to all the weights continues to rotate at the usual winding speed.

Then, when the thread is connected by a thread connecting device or the like not shown in the figure, and the coiling state is possible, the operator turns ON the start switch 250 of the spindle drive motor 206 which is stopped as shown in FIG. Rotate the spindle drive motor 206 again. When the start switch 250 is turned ON, the start control section 244a starts the spindle start motor 206 rapidly in about 10 seconds. As a result, the yarn Y can be shaped while the winding package P is stopped and the yarn Y is not running, so that the yarn Y can be prevented from being wound around the winding package P while being loosely twisted. have.

The release control part 244b transmits an opening / closing signal to the solenoid valve (SV 248) approximately 2 seconds after the start of the spindle drive motor 206. The solenoid valve SV 248 closes the valve to lower the pressure in the cylinder 253 and rotate the link arm 252. As a result, the link arm 252 is separated from the take-up package P and the take-up drum 221 approximately two seconds after the start of the spindle drive motor 206, so that the brake state of the take-up package P is released. do.

When the brake state is released, the winding package P again contacts the winding drum 221 which is rotating at the usual winding speed, and thus starts rotation. When about 8 seconds have elapsed since the start of rotation of the winding package P, the winding package P reaches the rotation speed in normal operation. On the other hand, the spindle drive motor 206 reaches the rotation speed in normal operation about 10 seconds from the start of rotation. In this manner, about 10 seconds after the start switch 250 is turned ON, the spindle drive motor 206 and the winding package P return to the rotation speed during normal operation.

In addition, the control power supply line 249 of the multiple twister 1 which concerns on a present Example is for supplying the control system voltage 24V for controlling the spindle drive motor 206 to each inverter 244. As shown in FIG. In addition, the control signal lines 257 and 258 are for transmitting a start command or a stop command to all the inverters 241 and 244 at the time of a power failure detection, and are for transmitting the simultaneous start or simultaneous stop signal of normal expectation. In addition, the communication lines 246 and 251 monitor the rotation speed of each motor 206, the command value for each motor 206, etc. by the host CPU 236, or each inverter 241, from the host CPU 236. 244) for setting parameters for control.

In addition, in the button-driven multiple twister 1 according to the present embodiment, when the spindle drive motors 206 are simultaneously started, the start of each spindle drive motor 206 simultaneously with the winding drum 221 common to all the weights is performed. Since it starts and accelerates smoothly at the same ratio, the slip of the winding drum 221 and the winding package P can be prevented, and the thread cutting at the time of starting can be prevented. In addition, as an operation | movement at the time of simultaneous starting, when the power supply is first turned on, the package brake 230 is released and the package P and the winding drum 221 contact. Thereafter, upon start-up, rotation of the spindle device 202 together with the winding drum 221 is started.

In addition, in this embodiment, although the release control part 244b controlled to release the winding package brake 230 after the predetermined time (2 second) passed, it is not limited to this, The rotation detector 255 (refer FIG. 11). Based on the rotational speed from), when the spindle drive motor 206 reaches the predetermined rotational speed, the winding package brake 230 may be released to release. Thereby, the release of the winding package brake 230 can be performed at a more accurate timing.

In addition, when the spindle drive motors 206 are started simultaneously, the start time is set to about 15 to 20 seconds, but is not limited thereto. In addition, when starting the spindle drive motor 206 of arbitrary weights, the starting time was demonstrated to be about 10 second, However, it is not limited to this.

In the present embodiment, the inverter 244 for the spindle drive motor constitutes each unit control unit 209 for each 32 units, but the number of the inverters 244 is not limited to 32 units. In addition, although it was demonstrated that two spindle drive motors 206 are connected to the inverter 244 for spindle drive motors, the number of spindle drive motors is not limited to two. In addition, although the case where the single feed chamber package 208 is formed in each thread winding unit U was demonstrated, it is not limited to this and may be formed in multiple numbers. The DC brushless motor has a rotation speed detector 255 for detecting the rotation speed.

In the third embodiment, in the button-driven multi-burst machine that drives the plurality of spindle drive motors 206 provided for each spindle 103 by the speed control device 44, the speed control device 44 is a motor. In the case of driving 206 and the case in which many motors 6 are driven simultaneously, control is performed so that the time from the start of the operation until reaching a predetermined speed is different. That is, the rotation speed control device 44 is equipped with the starting control means which starts rapidly, when each drive, and starts normally (slower than each case) when it drives simultaneously. As a result, it is possible to prevent loose twisting due to sudden driving, and to suppress the increase of the current value in the control system even though the driving is performed simultaneously by the gentle driving.

Each drive can be performed by operating the operation means (start switch) 50 for each weight, and the simultaneous drive can be performed by operating the main body control device 42. In addition, in the third embodiment, the plurality of winding package brakes 30 which prevent the winding to the winding package and the brake state of the winding package brake 30 are released at a predetermined timing with respect to the rotation of the motor 206. Since it has a release control means for making it, it can drive automatically, without using the pedal type brake for preventing a winding package like conventionally, and can prevent loose twisting.

In addition, in the first to third embodiments, a double twister for applying two twists to the yarn Y by one rotation of the spindle device has been described as an example of the button-driven multiple twister. Or a quadruple twister.
