본 발명은 자동차 조립용 공구의 이송장치에 관한 것으로, 더욱 상세하게는 자동차 엔진등의 조립공정이 이루어지는 자동이송라인에 설치되며, 엔진의 장착시 엔진룸의 정위치에 놓인 엔진을 용이하게 조립할 수 있도록 하기 위해서 엔진 조립용 공구가 놓인 이송장치가 자동차의 자동이송 리프트를 따라 이동되도록 한 자동차 조립용 공구의 자동이송장치에 관한 것이다.The present invention relates to a transfer device for a vehicle assembly tool, and more particularly, is installed in an automatic transfer line in which an assembling process such as an automobile engine is performed, and when an engine is mounted, an engine placed at a proper position in an engine room can be easily assembled. The present invention relates to an automatic transport device for an automobile assembly tool, in which a transport device on which an engine assembly tool is placed is moved along an automatic transport lift of a vehicle.

일반적으로 자동차의 생산라인은 자동으로 이루어지고 자동이송장비에 의해 자동차가 이동되며, 이동중인 자동차에 작업자도 같이 따라 움직이면서 각종 부품을 체결하는 작업을 하는 바, 특히 자동차의 엔진조립작업은 엔진룸에 엔진을 정위치에 올려놓은 상태에서 볼트체결 작업장으로 자동이송 리프트를 이송시키게 되는데, 이때 작업자는 자동이송 리프트에 의해 이송되는 자동차를 따라 같이 움직이면서 엔진을 차체에 볼트체결을 해야 했다. 따라서 엔진을 조립하기 위한 토오크렌치와 같은 공구도 같이 휴대하거나 근접되는 위치에 놓고 먼저 볼트를 임시적으로 끼워넣은 상태에서 토오크렌치를 들고와 볼트를 체결하여 엔진조립을 완료하던지 두명의 작업자가 각각 볼트를 끼우는 작업과 토오크렌치로 체결하는 작업으로 분리하여 작업을 해야 했다.In general, the production line of the car is made automatically and the car is moved by the automatic transfer equipment, and the worker moves along with the moving car to fasten the various parts, especially the engine assembly work of the car in the engine room. With the engine in place, the automatic transfer lift is transferred to the bolting workshop, where the operator had to bolt the engine to the body while moving along with the vehicle being transported by the automatic transfer lift. Therefore, a tool such as a torque wrench for assembling the engine should also be carried or placed in close proximity, and the engine should be completed by first holding the torque wrench and tightening the bolt with the bolt temporarily inserted. The work had to be separated into the work of fitting and tightening with a torque wrench.

특히, 작업시 작업자는 자동이송 리프트에 올라가 작업을 해야 하는데 작업이 완료되면 다시 내려와 대기하다가 다음 자동이송 리프트에 의해 자동차가 이송되면 다시 작업자는 자동이송 리프트에 올라가서 엔진을 볼트체결해야 했기에, 중량체인 볼트체결용 토오크렌치를 작업자가 들고 자동이송 리프트에 올라갔다 내려오는 과정을 되풀이해야 하므로 작업자에게는 피로가 가중되고 어떤 경우에는 중량체인 토오크렌치를 놓쳐 안전 사고가 발생되는 문제점이 있었다.Particularly, the worker should go up to the automatic transfer lift to work, but when the work is completed, he will come back down and wait, and when the car is transported by the next automatic transfer lift, the worker should climb to the automatic transfer lift and bolt the engine, As the worker tightens the bolt tightening torque wrench up and down on the automatic transfer lift, the worker is fatigued, and in some cases, there is a problem that a safety accident occurs due to the weight chain torque wrench being missed.

즉, 작업자는 중량이 큰 토오크렌치 등의 공구를 들고 자동이송 리프트에 올라가 자동차의 엔진 등을 조립해야 했기에 피로가 가중되었고, 토오크렌치를 한명의 작업자가 들고 다니면서 이송라인에 올라갔다 내려오는 반복동작을 해야 했기에 안전사고의 발생위험도 있었는 등 매우 번거롭고 불편하였다.In other words, the worker had to carry a tool such as a heavy torque wrench and climb the automatic transfer lift to assemble the engine of the car. It was very cumbersome and inconvenient, because there was a risk of a safety accident.

본 발명은 이와 같은 종래의 문제점을 감안하여 안출한 것으로, 자동이송되는 자동차 리프트에 나란히 근접되게 설치되어 리프트와 같은 속도로 이송되는 이송장치를 설치하고, 이 이송장치에 토오크렌치 등의 공구를 장착시켜 작업시 이들 공구를 꺼내어 사용할 수 있도록 하고, 작업이 완료되면 자동으로 후진되어 엔진 조립 등을 하기 위해 이송되는 다음 자동차의 리프트 일측으로 이송되도록 한 자동차 조립용 공구의 자동이송장치를 제공하므로서, 작업완료후 작업이동시 중량이 큰 공구를 작업자가 들고 다니는데 따른 피로감이 줄어들게 될 뿐만 아니라, 작업시 공구를 놓치므로 인해 발생되는 안전사고의 위험도 제거되도록 하는데 있다.The present invention has been made in view of the above-described conventional problems, and installed in parallel with a car lift that is automatically transported to install a transport device that is transported at the same speed as the lift, and a tool such as a torque wrench is mounted on the transport device. It is possible to take out these tools during work and use them, and when the work is completed, it provides an automatic transfer device for the vehicle assembly tool which is automatically retracted to be transported to one side of the lift of the next car which is transported for assembly of the engine. When the work is moved after completion, the fatigue caused by carrying a heavy tool is not only reduced, but also the risk of a safety accident caused by missing a tool during work is eliminated.

이와 같은 본 발명의 목적은 자동차의 조립공정이 이루어지는 자동이송 리프트의 측면에 위치되게 설치한 레일을 따라 로울러가 모우터에 의해 구동되게 하고 상기한 모우터가 일단에 장착한 리미트스위치의 접점에 의해 역회전되게 하며, 타단에 장착한 리미트스위치의 접점에 모우터가 정지되게 하고, 외측에 원통형의 체결구를 형성하여 상기한 체결구에 엔진 조립작업 등에 사용되는 각종 공구를 끼워 넣으므로써 달성될 수 있는 것이다.The object of the present invention is to allow a roller to be driven by a motor along a rail installed on the side of an automatic transfer lift in which an automobile assembly process is performed, and by the contact of a limit switch mounted at one end of the motor. It can be achieved by reverse rotation, stop the motor at the contact point of the limit switch mounted on the other end, and form a cylindrical fastener on the outside to insert various tools used for engine assembly work in the fastener. It is.

한편, 상기한 연결수단(50)은 상기 구동로울러(31)와 모우터(40)에 장착한 기어(51)와, 상기 기어(51)에 체결시킨 체인(52)으로 구성한 것이다.On the other hand, the connecting means 50 is composed of a gear 51 mounted to the drive roller 31 and the motor 40, and a chain 52 fastened to the gear 51.

이하, 본 발명의 작용·효과를 설명하면 다음과 같다.Hereinafter, the operation and effect of the present invention will be described.

제3도는 본 발명의 사용상태를 보인 개략도로서, 엔진룸에 엔진(3)을 정위치시킨 상태에서 자동차(1)를 이송시켜 엔진(3)을 고정시키는 작업까지의 과정을 설명하면 다음과 같다.3 is a schematic view showing a state of use of the present invention. The process up to the operation of fixing the engine 3 by transporting the vehicle 1 in the state in which the engine 3 is positioned in the engine room is as follows. .

엔진(3)이 정위치에 탑재된 자동차(1)가 자동이송 리프트(12)에 의해 볼트체결 작업장으로 이송되면, 대기중인 작업자는 리프트(2)에 올라간 상태에서 이송장치(100)의 체결구(80)에 놓인 토오크렌치(4)를 꺼내면서 구동스위치(60)를 접점시켜 모우터(40)를 구동시키고, 꺼낸 토오크렌치(4)로 엔진(3)을 자동차(1)에 볼트체결하면 되는데 이때, 자동차(1)가 올려있는 리프트(2)와 토오크렌치(4)(5)가 놓여있는 이송장치(100)는 같은 속도로 이송되고 있으므로, 작업자는 필요에 따라 다른 크기의 토오크렌치(5)를 꺼내어 엔진(3)를 볼트체결할 수 있고, 체결작업이 완료되면 토오크렌치(5)를 체결구(80)에 끼워 넣고 자동이송 리프트(2)에서 내려와 다음에 이송된 자동차(1)를 대기하면 되는 것이다.When the vehicle 1 on which the engine 3 is mounted in the home position is transferred to the bolting work place by the automatic transfer lift 12, the waiting worker is fastened to the lift device 2 in the state where the worker 3 is on the lift 2. When the torque wrench 4 placed in the 80 is removed, the drive switch 60 is contacted to drive the motor 40, and the engine 3 is bolted to the vehicle 1 with the removed torque wrench 4. At this time, since the lift device 2 on which the vehicle 1 is placed and the conveying device 100 on which the torque wrenches 4 and 5 are placed are being transported at the same speed, the worker may have different torque wrenches having different sizes as needed. 5) take out and bolt the engine (3), and when the tightening operation is completed, insert the torque wrench (5) into the fastener (80) and descend from the automatic transfer lift (2) and then transported the car (1) Wait for it.

한편, 이송장치(100)가 이동되는 레일(10)의 길이는 엔진(3)의 볼트체결 작업시간에 대한 이동되는 거리를 계산하여 정해놓은 것으로 체결작업이 완료되면 이송장치(100)도 레일(10)의 끝단에 위치하게 되는데 이때, 역동리미트스위치(71)가 레일(10) 일단의 스톱퍼(11)에 의해 스위칭접점되어 모우터(40)는 역회전하여 원래의 위치로 돌아오게 되며, 이때에도 제동리미트스위치(72)가 원래의 출발위치에 돌설시킨 스톱퍼(12)에 의해 접점되면서 모우터(40)의 전원이 단전되어 이송장치(100)가 원래의 위치에서 정지하게 되는 것이다.On the other hand, the length of the rail 10 to which the conveying device 100 is moved is determined by calculating the moving distance with respect to the bolting work time of the engine 3, and when the fastening work is completed, the conveying device 100 is also a rail ( 10), the reverse limit switch 71 is switched by the stopper 11 at one end of the rail 10 so that the motor 40 is rotated back to its original position. Edo braking limit switch 72 is contacted by the stopper 12 protruding to the original starting position, the power of the motor 40 is cut off so that the transfer device 100 is stopped at the original position.

이와 같이 원래의 위치로 복귀된 이송장치(100)는 구동스위치(60)의 조작으로 다시 리프트(2)와 같은 속도로 이송되어 작업자에게 토오크렌치(4)(5)는 물론 공구 및 부품을 제공하게 되는 것으로, 이에 따라 자동차의 조립작업이 용이하게 이루어지고 작업자의 작업반경이 최소화되어 작업능률이 향상되는 것이다.In this way, the conveying apparatus 100 returned to its original position is conveyed again at the same speed as the lift 2 by the operation of the drive switch 60 to provide the worker with the torque wrench 4 and 5 as well as tools and parts. As a result, the assembly of the vehicle is made easy and the work radius of the worker is minimized to improve the work efficiency.
