본 고안은 고정체와 이동체를 갖고 한 방향으로만 이동하여 특정제품을 무인으로 자동반입 및 반출하는 용접 시스템용 무인반송대차의 제어장치에 관한 것으로서, 특히 광모뎀을 사용하여 정밀 제어를 할 수 있도록 하는 무인반송대차의 제어장치에 관한 것이다.The present invention relates to a control device for an unmanned transfer truck for welding systems that has a fixed body and a moving body moving in only one direction and automatically carries and unloads a specific product. In particular, the optical modem can be used for precise control. It relates to a control device of the unmanned transfer truck.
일반적으로 용접시스템용 무인반송대차는 고정체와 이동체를 갖고 있으며 일정한 거리를 한 방향으로만 왕복 주행하여 특정제품을 지정된 위치에 반입 또는 반출하는 장치이다.In general, the unmanned transfer trolley for welding systems is a device that has a fixed body and a moving body, and carries or exports a specific product to a designated location by reciprocating a certain distance only in one direction.
일반적으로 무인반송대차의 이동시스템은 중장비의 일부품을 로보트에서 용접을 실시하면 반송대차가 용접완료된 제품을 지정된 장소로 반출하거나 용접위치로 반입하게 되며 무인으로 제어하도록 구성되어 있다.In general, the unmanned transfer truck's mobile system is configured to carry out unmanned conveyance of the heavy equipment in the robot and to carry out the welded product to the designated place or to the welding position.
이와같이 기존 사용되는 무인반송대차는 케이블 베어를 통해 신호송, 수신용 케이블을 설치하여 사용함으로써 무인반송대차의 이동거리가 멀거나 이동속도가 빠른 경우 케이블 베어를 설치할 수 없는 여건이 되어 무인반송대차의 원만한 기능을 수행할 수 없게 되는 문제점이 발생하게 된다.In this way, the unmanned transport truck used in the past is installed by using cables for signal transmission and reception through cable bears, so if the moving distance of the unmanned transport truck is long or the speed is high, the cable bear cannot be installed. There is a problem that can not perform a smooth function.
본 고안은 상기와 같은 문제점을 해소하기 위한 것으로써 본 고안의 목적은 무인반송대차의 고정체와 이동체에 적외선 광모뎀을 설치하여 광통신에 의해 프로그래머블 로직 콘트롤러(Programable Logic Controller : 이하 "PLC"라 함)에서 광신호를 판독하여 무인반송대차를 제어함으로써 고정체와 이동체간의 정밀제어가 가능하도록 하는 무인 반송대차의 제어장치를 제공하는데 있다.The present invention is intended to solve the above problems, and the object of the present invention is to install an infrared optical modem in the fixed body and the mobile body of the unmanned transport truck, and by the optical communication programmable logic controller (hereinafter referred to as "PLC") The present invention provides a control device for an unmanned transfer truck that enables precise control between a stationary body and a moving body by controlling an unmanned transfer truck by reading an optical signal.
상기와 같은 목적을 달성하기 위한 본 고안의 특징은, 고정체와 이동체를 구비하고, 상기 고정체와 이동체 사이에 신호를 송수신하여 이동체의 제어를 행하는 무인방송대차의 제어장치에 있어서, 상기 이동체의 소정위치에 적외선 신호를 주고받을 수 있는 적외선 신호 송수신수단 ; 상기 고정체에 장착된 컴퓨터로부터 제어신호를 수신하여, 그 수신된 신호를 상기 적외선 송수신 수단을 통하여 제어하는 프로그램 로직 컨트롤러; 상기 이동체의 적외선 송수신수단과 적외선 신호를 주고받을 수 있는 고정체의 적외선 송수신 수단 ; 및 상기 고정체의 적외선 송수신 수단의 신호를 멀티플렉싱하여 고정체의 메인콘트롤러인 컴퓨터에 보내는 멀티플렉서로 구성된 무인반송대차의 제어장치에 있다.Features of the present invention for achieving the above object, in the control device of the unmanned broadcasting bogie comprising a stationary body and a mobile body, and controls the moving body by transmitting and receiving a signal between the fixed body and the mobile body, Infrared signal transmission and reception means for transmitting and receiving an infrared signal at a predetermined position; A program logic controller which receives a control signal from a computer mounted on the fixed body and controls the received signal through the infrared transmitting and receiving means; Infrared transmitting and receiving means of a fixed body capable of transmitting and receiving infrared signals with the infrared transmitting and receiving means of the moving object; And a multiplexer which multiplexes the signal of the infrared transmitting / receiving means of the stationary body and sends the signal to a computer which is the main controller of the stationary body.
제1도는 본 고안의 일실시예를 나타낸 준장비 특정부품의 용접 및 용접 완료된 제품을 반입 또는 반출하는 무인반송대차의 개략도이고, 제2도는 본 고안에 따른 무인반송대차의 제어장치의 블럭도이다.FIG. 1 is a schematic diagram of an unmanned transfer truck for carrying in or carrying out a welded or welded product of a semi-equipment specific part showing an embodiment of the present invention, and FIG. 2 is a block diagram of a control device for an unmanned transfer truck according to the present invention. .
제1도 및 제2도를 참조하여 설명하면, 이동체(10)(무인반송대차)가 반입스토크(18)에 있는 제품을 싣고 이동하여 용접로봇(13-16)에 로딩시켜주고, 용접 완료된 제품을 이동체(10)가 싣고 반출 스토크(17)에 로딩시켜주는 동작을 반복하게 된다.Referring to FIG. 1 and FIG. 2, the moving body 10 (unmanned transfer truck) loads and moves the product in the carrying stock 18, loads it on the welding robot 13-16, and welds the finished product. It repeats the operation to load the moving body 10 to the carrying out stoke 17.
이때 이동체(10)는 반입스토크(17')와 4대의 용접로봇(13-16) 그리고 4대의 리프트 스토크(20-30)와 연동동작이 되어야 하고, 이를 제어하는 제2내지 제6 PLC(1)(6-9)와 연동동작이 되어야 하므로 상기 제2내지 제6PLC(1)(6-9)와 이동체(10)에 탑재되어 있는 제1 PLC(18)와의 신호전송이 제1 및 제2광모뎀(3), (4)을 통하여 연동작동에 필요한 신호를 송수신하게 된다.At this time, the moving body 10 should be interlocked with the carry-in stoke 17 ', four welding robots 13-16 and four lift stokes 20-30, and control the second to sixth PLC (1). (6-9), so the signal transmission between the second to sixth PLC (1) (6-9) and the first PLC (18) mounted on the moving object 10 is the first and second Through the optical modem (3), (4) to transmit and receive the signals necessary for the interlocking operation.
즉, 이동체(10)의 제1 PLC(18)에서 제1광모뎀(3)으로부터 송신되는 신호 고정체에 설치된 제2광모뎀(4)에 수신되며, 이의 수신신호는 멀티 플렉서(19)를 통해 제2 내지 제6 PLC(1)(6-9)에 수신된 정보를 판독하여 그에 상응하는 제어신호를 상기 제2 내지 제6 PLC(1)(6-9)로 보내게 되고, 이는 다시 멀티플렉서(19) 및 제2광모뎀(3)을 통해 이동체(10)의 제1광모뎀(3)으로 송출하게 된다.That is, the second optical modem 4 installed in the signal fixture transmitted from the first optical modem 3 by the first PLC 18 of the moving object 10 is received by the multiplexer 19. Through reading the information received by the second to sixth PLC (1) (6-9) through the corresponding control signal to the second to sixth PLC (1) (6-9), which is The multiplexer 19 and the second optical modem 3 transmit the same to the first optical modem 3 of the moving object 10.
따라서 이동체(10)의 제1 PLC(18)는 컴퓨터(5)에서 명령한 제어 테이타를 판독하여 특정 물품을 지정된 위치에 반입 및 반출하기 위해 설정된 거리를 자동왕복운행하게 되는 것이다.Therefore, the first PLC 18 of the moving object 10 automatically reads the control data commanded by the computer 5 to automatically reciprocate the set distance for carrying in and taking out a specific article to a designated position.
이상에서 상술한 바와 같이 본 고안은 무인반송대차의 고정체와 이동체에 광모뎀을 설치하여 광통신에 의해 컴퓨터 및 프로그래머블 로직 콘트롤러에서 광신호를 판독하여 무인반송대차를 제어함으로써 신호 전송용 송수신케이블 설치가 불가능한 고정체와 이동체간의 정밀제어가 이루어질 수 있게 되는 것이다.As described above, the present invention installs an optical modem on a fixed body and a mobile body of an unmanned transport vehicle, reads an optical signal from a computer and a programmable logic controller by optical communication, and controls an unmanned transport vehicle to install a transmission / reception cable for signal transmission. It is possible to achieve precise control between the stationary body and the movable body.
