Description
본 발명은 취출기의 스텝 구동장치에 관한 것으로, 더욱 상세하게는 취출기를 1스텝씩 전진 또는 후진으로 조작되게 하여 그 동작 및 위치를 용이하게 점검할 수 있도록 한 것이다.The present invention relates to a step driving apparatus of a take-out machine, and more particularly, to allow the take-out machine to be operated forward or backward step by step so that the operation and position thereof can be easily checked.
주지하다시피, 사출기는 금형에 수지를 사출하여 자동차 범퍼, 전화기 케이스, 모니터 케이스와 같은 사출 성형품을 만드는 기기로서, 사출기로부터 사출된 성형품은 매우 뜨겁고, 사출기 자체가 매우 위험하기 때문에 통상 취출로봇과 같은 취출기를 통해 흡착패드로 흡착하거나, 척으로 파지하여 사출성형품을 취출하게 된다.As is well known, an injection molding machine is a device for making injection molded products such as automobile bumpers, phone cases, and monitor cases by injecting resin into a mold, and molded products injected from the injection machine are very hot, and the injection machine itself is very dangerous. The injection molded product is taken out by the suction pad or by the chuck through the blower.
이러한 취출기는 취출기 본체와 이를 구동하는 컨트롤러로 구성되는데, 컨트롤러에는 취출기 본체의 파지기구부 및 이동기구부를 구동하기 위한 프로그램이 내장되어 있어 이러한 프로그램에 따라 취출기 본체를 자동으로 구동할 수도 있고, 수동조작용 리모콘을 조작하여 수동으로 구동할 수도 있다.The extractor is composed of a main body of the ejector and a controller for driving the same. The controller includes a program for driving the gripping mechanism and the moving mechanism of the main body of the ejector. Manual operation You can also operate the remote control manually.
취출기의 구성 및 이를 자동으로 조작할 때의 기본동작과 신호흐름을 도 1을 참조하여 설명하면 다음과 같다.The configuration of the extractor and the basic operation and signal flow when automatically operating the same will be described with reference to FIG. 1 as follows.
먼저, 취출기(1)의 파지기구부(2)가 대기위치에 있는 상태에서 사출이 완료되어 사출신호가 오프되고 이와 동시에 안전도어가 온 되면 사출기(4)의 금형(5)을 형개시키며, 형개폐장치를 오프시켜 사출기(4)의 금형(5)이 닫히지 않도록 한 후 컨트롤러(미도시)의 명령에 따라 이동기구부(3)를 조작하여 파지기구부(2)를 하강위치로 이동시키게 되고, 파지기구부(2)의 하강이 완료되면 진공장치를 구동하여 흡착패드에 흡착력을 부여하면서 취출위치로 전진시키게 되며, 그 후에 지연시간을 갖고, 사출기(4)의 에젝터 구동장치를 전진시키게 된다.First, when injection is completed while the holding mechanism 2 of the ejector 1 is in the standby position, the injection signal is turned off and at the same time the safety door is turned on, the mold 5 of the injection machine 4 is opened. The switch 5 is turned off so that the mold 5 of the injection molding machine 4 does not close, and then the moving mechanism part 3 is operated by the controller (not shown) to move the holding mechanism part 2 to the lowered position. When the lowering of the mechanism part 2 is completed, the vacuum device is driven to advance to the take-out position while applying the suction force to the suction pad, after which the ejector driving device of the injection machine 4 is advanced.
에젝터가 전진완료되면 에젝터를 작동시켜 사출성형품을 밀어주게 되고, 지연시간을 가진 후 척크 또는 흡착패드, 제품집게를 작동시켜 성형품을 파지하게 되며, 이후 지연시간을 갖고 파지기구부(2)를 후진시켜 인발위치로 이동시키게 되며, 제품후진이 완료되면 지연시간을 갖고 파지기구부(2)를 상승시켜 제품을 상승시키게 되고, 제품 상승이 완료되면 에젝터 구동장치를 후진시킨 후 형개폐 구동장치를 온시켜 사출기(4)의 금형(5)이 닫힐 수 있도록 하며, 전자동을 온시켜 사출기(4)가 사출을 할 수 있도록 한다.When the ejector is completed, the ejector is operated to push the injection molded product, and after having the delay time, the chuck, the suction pad, and the tongs are operated to hold the molded product. It moves back to the drawing position, and when the product reverse is completed, it raises the product by raising the holding mechanism part 2 with a delay time, and when the product rise is completed, the ejector drive device is reversed and the mold opening and closing drive device is operated. By turning on the mold 5 of the injection molding machine 4 to be closed, and by turning on the fully automatic injection machine 4 to allow the injection.
그 후에 지연시간을 갖고, 주행위치로 파지기구부(2)를 이송하며, 주행이 완료된 후에는 지연시간을 갖고 회전시키게 되며, 회전이 완료되면 제 2하강위치로 파지기구부(2)를 하강시킨 후 지연시간을 갖고 흡착패드 또는 척크를 오프, 해제하여 사출 성형품을 놓은 후 흡착 오프인 흡착해제신호, 척크 오프인 척크해제신호를 받게 된다.After that, it has a delay time, transfers the holding mechanism part 2 to the traveling position, and after the driving is completed, it rotates with a delay time, and when the rotation is completed, lowers the holding mechanism part 2 to the second lowering position. With the delay time, the suction pad or the chuck is turned off and off to release the injection molded article, and then the suction off signal and the chuck off signal are received.
그 후에 내부지연시간을 갖고 제품측을 상승시키게 되며, 제품측 상승이 완료되면 컨베이어를 온시키면서 회전을 오프시키게 되고, 주행 복귀를 하여 최초 대기위치에 위치됨으로써 모든 동작이 완료된다.After that, the product side is raised with the internal delay time, and when the product side rise is completed, the rotation is turned off while turning on the conveyor, and the driving returns to the initial standby position, thereby completing all operations.
이러한 취출기는 사출기로부터 생산되는 제품에 따라 취출을 위한 동작 및 위치가 달라지게 되므로 이럴 경우 본 출원인의 선출원인 특허출원 제 2002-10528 호에 따른 취출기의 동작 설정방법 및 장치에 따라 새로이 동작 및 위치를 설정해 주어야 하며, 동작 및 위치가 설정된 후에는 실제 운전에 앞서 변경된 동작 및 위치의 설정을 1사이클운전을 통해 확인하게 된다.Since the ejector is different from the operation and position for ejection according to the product produced from the injection machine, in this case, the operation and position of the ejector according to the method and apparatus for setting the operation of the ejector according to the patent application No. 2002-10528, the applicant of the present applicant After the operation and position are set, the changed operation and position setting is confirmed through one cycle operation before the actual operation.
그런데, 이와 같은 1사이클 운전은 사출기가 생산한 제품을 취출하여 적재하는 전 과정을 1회 수행하는 것을 의미하므로 개략적인 동작 및 위치의 설정을 파악하는 것은 가능할지 모르나 각 동작을 구분지어 관찰할 수 없는 관계로 정확한 동작설정여부, 정확한 위치설정 여부를 판단하기가 매우 어려우며, 한 동작에 대해 다시 관찰하기 위해서는 전 공정을 처음부터 다시 수행해야만 하였으므로 전체 장치로 보아 매우 비효율적이며 불합리한 것이라 할 수 있다.However, such a one-cycle operation means that the entire process of taking out and loading the product produced by the injection molding machine is performed once, so it may be possible to grasp the rough operation and the setting of the position, but each operation can be observed separately. It is very difficult to determine whether the correct operation is set or not, since it is difficult to determine the correct operation position, and in order to observe the operation again, the entire process has to be performed from the beginning, which is very inefficient and unreasonable.
본 발명은 이러한 점을 감안하여 제안된 것으로, 취출기를 1사이클 운전하지 않고 한 동작씩 전진시키면서 동작시키거나 한 동작씩 역순으로 동작시켜 각 단계별로 취출기의 동작 및 위치를 구분지어 관찰할 수 있게 함으로써 정확한 동작 및 위치설정을 가능하게 하는 취출기의 스텝 구동장치를 제공하고자 하는 것이다.The present invention has been proposed in view of the above, and it is possible to operate the ejector by moving forward one by one operation without operating one cycle, or by operating in reverse order by one operation so that the operation and position of the ejector can be distinguished and observed at each step. It is therefore an object of the present invention to provide a step driving apparatus of a take-out machine which enables accurate operation and positioning.
