본 발명은 제직기의 저속 및 고속제어장치에 관한 것으로서 상세히는 간단한 구성을 구비하는 제직기에 있어서의 저속 및 고속변환운전을 제어하는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low speed and high speed control apparatus for a weaving machine, and more particularly, to an apparatus for controlling a low speed and high speed conversion operation in a weaving machine having a simple configuration.

종래에 제직기 구동용 모우터의 경우 속도를 변환시키기 위하여서는 사용주파수대 0-20㎐의 주파수변환 장치인 인버터(Inverter)를 사용하여 모우터의 회전 속도를 변환시킴으로서 제직기의 구동속도를 변환하였다.Conventionally, in order to convert the speed of the loom driving motor, the drive speed of the weaving machine is changed by converting the rotational speed of the motor by using an inverter (Inverter) which is a frequency conversion device of a frequency band of 0-20 Hz. .

그러나, 상기와 같이 종래의 인버터를 사용하는 방식의 제직기의 저속 및 고속제어 장치에 있어서는 하기와 같은 문제점을 가지고 있었다.However, the low speed and high speed control apparatus of the weaving machine using the conventional inverter as mentioned above had the following problems.

즉, 인버터 자체의 가격이 상당한 고가이고 주파수변환이 빈번하게 필요한 경우에는 고장이 다발하여 그 유지, 보수비용 또한 다대하여 직기가동의 부가적인 경비발생의 큰 비중을 차지하였다.In other words, if the price of the inverter itself is considerably high and frequency conversion is frequently required, the number of failures is high, and the maintenance and repair costs are also large, accounting for a large portion of the additional expense of loom operation.

또한 인버터의 고장의 경우, 전체 직기의 가동이 불가능하여 수리기간동안 직기를 휴지시켜야 하기 때문에 기회비용의 상실 또한 다대하였던 것이다.In the case of an inverter failure, the loss of the opportunity cost was also great because the whole loom cannot be operated and the loom must be stopped during the repair period.

상기와 같은 문제점을 해결하기 위하여 고안된 다른 하나의 통상적인 방법은 기어와 전자클러치를 구비하여 기계적인 변속을 도모하고 있으나 이러한 방식 역시 설치 원가가 높고 전자클러치의 고장시는 상기의 주파수변환에서와 같은 문제점이 발생하는 폐단이 있었다.Another conventional method devised to solve the above problems is to provide a mechanical shift with a gear and an electronic clutch, but this method also has high installation cost and failure of the electronic clutch as in the above frequency conversion. There was a problem that caused the problem.

이상과 같은 문제점을 감안하여 본 발명의 제직기의 저속 및 고속제어장치에서는 새로운 속도제어방법을 제공하는 것을 목적으로 한다.In view of the above problems, it is an object of the present invention to provide a new speed control method in the low speed and high speed control apparatus of the weaving machine of the present invention.

상기의 목적을 달성하기 위하여 본 발명에서는 극수변환에 의한 변속장치를 제공하는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized by providing a transmission by pole number conversion.

이하의 부수된 도면과 함께 본 발명의 제직기의 저속 및 고속제어장치를 더욱 상세하게 설명한다.The low speed and high speed control apparatus of the weaving machine of the present invention together with the accompanying drawings will be described in more detail.

제1도는 본 발명의 제직기용 모우터의 결선가능한 내부결선도, 제1도는 본 발명의 제직기용 모우터의 외부결선도, 제3도는 본 발명의 제직기용 모우터의 제어회로도로서 함께 설명한다.1 is a diagram illustrating the internal connection of the motor for a weaving machine of the present invention, FIG. 1 is an external connection diagram of the motor for the weaving machine of the present invention, and FIG. 3 is a control circuit diagram of the motor for the weaving machine of the present invention.

본 발명에서는 통상적인 극수전환방식을 제직기의 가동모우터에 구현하는 것을 기술적인 특징으로 한다.In the present invention, a technical feature is to implement a conventional pole number switching method in the moving motor of the weaving machine.

제직기가 정지하였을 경우 스타어레이(Star Array : Y폴결선) 기동용 전자접촉기(MSS)는 동작을 한다. 정지상태에서 푸쉬보턴(PF 또는 PR)을 동작할 때 정회전전자접촉기(MSF 또는 MSR)가 동작하여 모우터 리드선 7, 8, 9선 즉, Y폴결선의 스피드(S2)로 정회전 또는 역회전이 이루어진다.When the weaving machine is stopped, the magnetic contactor (MSS) for starting the star array (Y pole connection) is activated. When the pushbutton (PF or PR) is operated in the stopped state, the forward rotating magnetic contactor (MSF or MSR) is operated to rotate forward or reverse at the speed S2 of the motor lead wires 7, 8, and 9, that is, the Y-pole connection. Rotation takes place.

다음에 푸쉬보턴(PA)동작 다음에 푸쉬보턴(PF)을 순차적으로 동작할 때 고속기동용 전자접촉기(MSH)가 동작하여 중앙제어장치(C.P.U)의 명령에 따라서 델타(Delta)기동용 전자 접촉기(MSD)가 지정된 시간동안 동작하여 기동토오크를 소정의 값(예를들면 18배) 상승시키고 지정된 소정의 시간이 지나면 스트레이 기동(Y폴결선)용 전자접촉기가 동작하여 제직기는 정지 명령이전까지 운전한다.Next, when push button PF is operated in sequence, high-speed starting magnetic contactor MSH operates, and the Delta starting magnetic contactor is operated according to the command of central control unit (CPU). (MSD) operates for the specified time and increases the starting torque by a predetermined value (e.g. 18 times), and after the specified time passes, the magnetic contactor for stray start (Y-pole connection) operates and the weaving machine operates until the stop command. do.

고속기동용 전자접촉기(MSH)가 동작시는 X폴결선의 속도(S1)가 유지된다. 고속기동용전자접촉기(MSH)의 동작지령이 없을 경우 기계의 저속동작(슬로우동작 : Y폴결선)로서 역 1회전 촌동(Inching)이 정방향 또는 역방향으로 시행되는 것이다.When the high speed starting magnetic contactor MSH operates, the speed S1 of the X-pole connection is maintained. When there is no operation command of high speed starting magnetic contactor (MSH), low speed operation (slow operation: Y-pole connection) of the machine is performed in reverse or reverse rotation.

이상에서 각 결선은 전자접촉기의 선택적인 개폐에 의하여 이루어 결선구성이 이루어지는 것이며 전자접촉기는 통상의 광센서를 사용하는 방식이나 접점식등의 다양한 구성의 스위치가 사용될 수 있다.As described above, each connection is made by selective opening and closing of the magnetic contactor, and the connection configuration is made. The magnetic contactor may use a switch having various configurations such as a conventional optical sensor or a contact type.

이상과 같은 구성의 본 발명에 의하여 기존의 인버터 또는 기어방식에 비하여 각종의 추가부품이 대폭 줄어들게 되고 상당한 경비절감이 가능하며 제직기의 구조 또한 간단하게 구성되어 주모우터 1대로서 2가지의 가동속도를 구현할 수 있을 뿐만 아니라 고장 또한 적은 모우터의 변속장치를 제공하는 유용한 발명인 것이다.According to the present invention having the above-described configuration, various additional parts are greatly reduced and considerable cost reduction is possible, compared to the existing inverter or gear system, and the structure of the weaving machine is also simple and consists of two main speeds as one main motor. It is a useful invention that can provide a transmission of not only a fault but also a motor with fewer failures.
