본 발명은 공작기계의 절전제어장치에 광한 것이다. 종래의 공작기계의 제어장치의 일례를 제 1 도 내지제 3 도에 나타내었으며 그것은 운전준비", "비상정지및 "싸이클 스타트(Cycle Start)둥의 기능을 제어하는 것이머, 프로그램 제어부에 입력되는 신호에 따라 미리 프로그램되어있는 출력신호가 나타나 상기 기능을 행하도록햐는 것이다. .The present invention is broad in the power saving control device of the machine tool. An example of a control device of a conventional machine tool is shown in FIGS. 1 to 3, which control the functions of the operation preparation, the emergency stop, and the cycle start cycle, which are input to the program control unit. According to the signal, a pre-programmed output signal appears to perform the above function.

종래의 이러한 장치에서는 작업자가 공작기계를 가동하고자 운전준비용 누름스위치(PB1)를 누톤 다음 싸이클 스타트 누름스위치(PB2)를 누르면 가공을 시작할 수 있게되고 가공이 끝나면 기계는 "운전준비"상태에 있게되며 이때 작업자가 비상정지용 누름스위치(MPB1)를 눌러야만 기계가 정지하게 되는데 작업자는 보통 다음 작업태까지 계속해서 기계를 "운전준비" 상태로 유지시키는 경우가 많다. 그런데 공작기계를 이러함"운전준비"상태로 공운전시킨다면 전력소모는 매우커지게 되며, 이러한 전력소모를 방지하기위해 가공작업이 끝날때마다 정지용 누름스위치를 누른다면 상기 문제점을 해결할수 있으나 이것 또한 번거로움이 뒤따르는 문제점이 있는 것이다.In such a conventional apparatus, when the operator presses the operation preparation push switch (PB 1 ) and then cycle start push switch (PB 2 ) to start the machine tool, the machining can be started and the machine is in the state of "ready to operate" In this case, the machine stops only when the operator presses the emergency stop push switch (MPB 1 ). The operator usually keeps the machine "ready to run" until the next working state. However, if the machine tool is operated in such a state as "ready to operate", the power consumption becomes very large. To prevent such power consumption, the above problem can be solved by pressing the stop push switch at the end of the machining operation. There is a problem that follows.

본 발명은 종래의 이러함 문제점을 해결하기 위한 방책의 일환으로 절전 제어장치를 이용하여 일정시간이 지나도 작업을 시작하지 않으면 기계를 자동으로 정지시키케한 것으로서 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention as a part of the measures for solving the conventional problems as described above in detail based on the accompanying drawings as to stop the machine automatically if the operation does not start even after a certain time using the power saving control device as follows. same.

본 발명은 제 4 도에 나타낸 바와같이 공작기계의 프로그램 제어부(10)의 입력단(X0-X5)에 각각 교류전원에 연결된 운전준비용 누름스위치(PB1), 비상정지용 누름스위치(MPB1), 싸이클 스타트용 누름스위치(PB2), 자동 및 수동 모드 누름스위치(SS1)와 기계정지용 타이머의 접점(t0)을 연결하고 출력단(Y0-Y5)중 세개의 출력단(Y0,Y1,Y3)에 각각 교류 전원에 연결된 운전준비 표시등(PL1), 싸이클 스타트 표시등(PL2)과 기계정지용 타이머(T0)를 연결함을 특징으로 한다.As shown in FIG. 4, the operation preparation press switch PB 1 and the emergency stop push switch MPB 1 connected to AC power at input terminals X 0 to X 5 of the program control unit 10 of the machine tool, respectively, as shown in FIG. , Connect the cycle start push switch (PB 2 ), the automatic and manual mode push switch (SS 1 ), and the machine stop timer contact (t 0 ), and the three output stages (Y 0 , Y 0 -Y 5 ). Y 1 and Y 3 ) are connected to the AC ready power indicator (PL 1 ), cycle start indicator (PL 2 ) and the machine stop timer (T 0 ), respectively.

제 4 도의 프로그램 제어부 입력/출력 다이아그램에서 운전준비용 누름스위치(PB1)를 누르면 "비상정지" 상태가 아닐 경우 기계는 "운전준비"상태로 되며 동시에 운전준비 표시등(PL1)이 점등된다.The fourth degree program control input / output by pressing the preparation for the operation push switch (PB 1) for in a diagram If it is not an "emergency stop" state machine "ready for operation", and the state light is at the same time driving the ready light (PL 1) do.

"비상정지"상태라 함은 비상정지용 누름스위치(MPBl)가 오프되어 기계가 정지되어 있는 상태를 뜻한다. 상기 :운전준비" 상태에서 가공소재를 가공하기위해 싸이클 스타트용 누름스위치(PB2)를 누르면 싸이클스타트 표시둥(PL2)이 점등되며 기계는 가공하기 시작한다."Emergency stop" means that the emergency stop push switch (MPBl) is off and the machine is stopped. When the cycle start push switch (PB 2 ) is pressed to process the workpiece in the "Ready to run" state, the cycle start indicator (PL 2 ) lights up and the machine starts to process.

가공이 완료된 후 일정시간이 지나도 싸이클 스타트용 누름스위치(PB2)를 누르지 않으면 기계정지용 타이머(To)의 합시접점(t0)이 오프되어 기계는 정지하게 되는 것이다.If the cycle start push switch (PB 2 ) is not pressed even after a certain time has passed after the machining is completed, the time contact point t 0 of the machine stop timer (To) is turned off and the machine is stopped.

상기 타이머의 작동시간은 작업자가 편리하게 조정될수 있는 것이다.The operating time of the timer can be conveniently adjusted by the operator.

이상에서와 같이 본 발명은 한 소재의 가공이 끝난후 일정시간이 지나도 작업을 시작하지 않으면 기계를 정지시켜 기계의 공운전을 최소화 하므로써 절전 효과가 큰 유용한 발명인 것이다.As described above, the present invention is a useful invention having a great power saving effect by minimizing the idle operation of the machine by stopping the machine if the work is not started even after a certain time after the processing of one material.
