인쇄기의 3축변위 제어장치{APPARATUS FOR CONTROLLING DISPLACEMENT OF THREE-AXES IN PRINTING MACHINE}Three-axis displacement control device of printing machine {APPARATUS FOR CONTROLLING DISPLACEMENT OF THREE-AXES IN PRINTING MACHINE}

본 발명은 잉크인쇄기의 3축변위 제어장치에 관한 것으로, 더욱 상세하게는 인쇄기에 있어서 잉크롤과 인쇄롤의 x,y,z축변위를 정확히 제어하는 인쇄기의 3축변위 제어장치에 관한 것이다.The present invention relates to a three-axis displacement control device of an ink printer, and more particularly, to a three-axis displacement control device of a printer for accurately controlling the x, y, z axis displacement of the ink roll and the printing roll in the printing machine.

일반적으로, 인쇄기는 잉크분사노즐판에서 잉크롤의 외주면에 잉크를 분사하여 도포하게 되면 잉크롤과 접촉하는 인쇄롤의 외주면에 잉크가 도포되고, 인쇄롤의 잉크를 이용하여 인쇄롤과 안내롤 사이로 진행되는 인쇄물에 인쇄가 이루어지게 된다.In general, when a printer sprays ink onto an outer circumferential surface of an ink roll from an ink spray nozzle plate, ink is applied to an outer circumferential surface of a printing roll in contact with the ink roll, and between the printing roll and the guide roll using the ink of the printing roll. Printing is performed on the printed matter in progress.

이때, 잉크분사노즐판과 잉크롤, 잉크롤과 인쇄롤, 인쇄롤과 안내롤의 간격은 인쇄의 선명도에 절대적인 영향을 미치게 되고, 이 간격은 x,y,z축에 대해 이루어지게 된다.At this time, the interval between the ink jetting nozzle plate and the ink roll, the ink roll and the printing roll, the printing roll and the guide roll has an absolute influence on the sharpness of the printing, and this interval is made about the x, y, z axis.

그러나, 종래의 인쇄기에서는 잉크분사노즐판과 잉크롤, 잉크롤과 인쇄롤, 인쇄롤과 안내롤의 간격을 조정함에 있어 먼저 스탭핑모터를 이용하여 어느정도 조정한 다음, 정밀한 조정은 작업자가 수동으로 행하게 된다.However, in the conventional printing press, in adjusting the interval between the ink jetting nozzle plate and the ink roll, the ink roll and the printing roll, the printing roll and the guide roll, first adjust the degree to some extent by using a stepping motor, and then perform precise adjustment by the operator manually. Will be done.

이처럼, 종래에는 잉크인쇄기의 잉크분사노즐판과 잉크롤, 잉크롤과 인쇄롤, 인쇄롤과 안내롤의 간격을 작업자가 육안으로 수동 조정함으로써 정확성이 떨어질 뿐만 아니라 이로 인해 인쇄의 정확성 및 선명도가 저하되는 문제가 야기된다.As such, in the related art, the operator manually adjusts the distance between the ink jetting nozzle plate and the ink roll, the ink roll and the printing roll, the printing roll and the guide roll of the ink printer, and the accuracy is not only lowered, thereby reducing the accuracy and sharpness of the printing. Problem is caused.

본 발명은 이러한 종래의 문제를 개선하기 위하여 안출된 것으로, 인쇄기에 있어서 잉크롤과 인쇄롤의 x,y,z축변위를 정확히 제어함으로써 인쇄의 선명도 및 생산성을 높이게 되는 잉크인쇄기의 3축변위 제어장치를 제공함에 그 목적이 있다.The present invention has been made to solve such a conventional problem, the three-axis displacement control of the ink printer to increase the sharpness and productivity of printing by accurately controlling the x, y, z axis displacement of the ink roll and the printing roll in the printing press The object is to provide a device.
