Abstract
The utility model relates to an electric control device for a cotton spinning machine, more specifically a synchronous parking control device when multiple motors suddenly fail power. The utility model is suitable for synchronous parking control when multiple motors on a roving machine without cone pulleys are in sudden power cut. The utility model comprises a controller and a plurality of motors, wherein, a plurality of motors are connected with the same three-phase alternating-current power supply by frequency converters. The utility model has the structural characteristics that direct-current terminals on the frequency changers are connected in parallel, and the two direct-current terminals are connected by a capacitor. An uninterrupted power supply is connected among the controller, the three-phase alternating-current power supply and an input terminal of the frequency changer.
Description
Technical field
The utility model relates to the cotton spinning machine electrical control gear.Synchronous shutoff control unit when specifically, being the unexpected power down of multiple electric motors.Be applicable to the synchronous parking control of multiple electric motors when having a power failure suddenly on the no cone pulley Speed frames.The utility model comprises
Background technology
The reeling roving of no cone pulley Speed frames is that rove enters in the flier revoliving arm, passes and is wound up on the bobbin from flyer presser, by means of moving up and down of down rail rove is wrapped on the bobbin round and round by the front roller rove that spues equably.This shows that the regular coiling of rove is cooperated synchronously and could be realized by front roller motion, flier motion and down rail elevating movement three aspects, and above-mentioned three move greatly respectively by one independently motor drive.And the operation of motor is controlled by frequency converter.Under the normal power supply situation, use this device can realize the rule coiling of rove.But when unexpected power-off condition occurring, because the uncontrollable motor of frequency converter dead electricity, machinery inertial free parking is separately pressed in above-mentioned three big athletic meeting, and three motors can not stop synchronously, will cause breaking of rove.So, the hundreds of ingot rove on Speed frames needs repiece again, not only bothers, increased working strength of workers, has also reduced production efficiency and product quality.
Summary of the invention
The purpose of this utility model is to provide a kind of many motor synchronous shutoff control unit.Use this device, can realize the synchronous parking of multiple electric motors, can avoid not only that rove is broken, the trouble of repiece again, also can reduce working strength of workers.And, improve production efficiency and product quality greatly.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Many motor synchronous shutoff control unit of the present utility model comprises controller and several motors, all is connected to frequency converter between some motors wherein and same three-phase alternating-current supply.Its design feature is that the dc terminal on the said frequency converter is in parallel, and is connected to capacitor between two dc terminals.Be connected to uninterrupted power source between said controller and above-mentioned three-phase alternating-current supply and frequency converter input terminal.
Adopt such scheme, have the following advantages:
Owing to be connected to uninterrupted power source between controller and power supply and frequency converter input terminal, when the unexpected power down of external power source, uninterrupted power source can provide a stabilized power source to make its energy operate as normal to controller.Meanwhile, after controller receives power-off signal, call the Synchronization Control subprogram of unexpected power down immediately, send the control signal of synchronous parking to frequency converter.
Because the dc terminal on a plurality of frequency converters is in parallel, and be connected to the capacitor that energy storage is used between two dc terminals again, when electricity is arranged, the capacitor energy reserve.During power down, capacitor releases energy and to frequency converter it is worked on, thereby the control motor stops fast.In docking process, equipment itself also has portion of energy can feed back to frequency converter, and frequency converter becomes direct current to be put in its DC terminal this part power conversion, and the electric energy that is used from frequency converter with the direct current one of capacitor stores is supplied with.The many motor synchronous that like this, finally realized outside unexpected power down are stopped.Not only avoid rove to be broken, needed the trouble of repiece again, also can reduce labour intensity, improve production efficiency and product quality.
Description of drawings
Accompanying drawing is many motor synchronous shutoff control unit schematic diagram of the present utility model.
The specific embodiment
As shown in drawings, many motor synchronous shutoff control unit of the present utility model comprises controller 2 and three motors 7.Three motors 7 wherein move greatly by front roller, flier revolution and down rail lifting three that it removes to drag Speed frames.The input of three motors 7 all joins by the lead-out terminal 8 of lead and corresponding three frequency converters 9, and the input terminal 4 of three frequency converters 9 all is connected with a three-phase alternating-current supply 1.Two dc terminals 5 are all arranged on three frequency converters 9, be connected to a capacitor 6 that is used for energy storage between these two dc terminals.5 of dc terminals on three frequency converters 9 are in parallel, and promptly adopt the common DC bus form.
Be connected to uninterrupted power source 3 between said controller 2 and single phase poaer supply.Single phase poaer supply wherein is the line voltage in the described three phase mains 1.
