Description
본 발명은 순차 이송되는 가공품의 정위치 여부를 감지하여 오작동을 방지토록 한 순차 이송 프레스기의 가공품 정위치 감지장치에 관한 것이다.The present invention relates to a workpiece position detection device of a sequential transfer press machine to detect whether the workpiece is sequentially transported in order to prevent malfunction.
종래에 순차 이송 프레스기는 첫피치에서 가공품의 불필요한 부분에 돌부를 절곡형성하여 순자척 이송시 하부금형의 측부에 설치 고정되는 텃치 스위치나 또는 투수광식 광센서 등이 이송된 가공품의 정위치 여부를 감지토록 한 것으로서, 이러한 경우 금형의 제조후 가공품이 갖는 순차적인 이송거리 내지는 가공품에 돌출형성된 돌부의 돌출 지점 등에 따라 위치를 지정하여 해당 위치에 오차없이 정확하게 설치 고정해 주어야 하므로 셋팅 작업이 매우 까다롭고 시간이 많이 소요되며, 또한 가공품은 순차적인 프레싱작업으로 인하여 이송시 갈수록 큰 폭의 떨림이 주어지게 되므로 이러한 떨림시에는 센서가 신호를 받지 못해 애러가 발생된다.또한 일본공개특허 평2-197398호와 같이 정규이송위치의 파일롯구멍과 대향하는 검출핀을 구동장치에 의해 파일롯구멍 내에 진출시켜 그 검출핀이 가공품과 접촉하는지 아닌지에 따른 다른 변화전압으로 검출되도록 한 것이 있으나 이는 복잡한 구성으로 제조경비가 과다소요되고, 잦은 고장을 유발시키게 되며 검출을 위한 별도의 시간을 필요로 하므로 작업능률이 저하되는등 많은 문제점들이 있는 것이다.Conventionally, the sequential transfer press machine detects the correct position of the workpiece to which the quench switch or the light transmitting optical sensor, etc., which is installed and fixed to the side of the lower mold during the forward chuck transfer, is formed by bending the protrusion on the unnecessary part of the workpiece at the first pitch. In this case, the setting work is very difficult and time consuming because it is necessary to designate the position according to the sequential transfer distance of the processed product after the manufacture of the mold or the protruding point of the protrusion formed on the processed product. In addition, the workpiece is subjected to a tremendous tremor as it is transported due to the sequential pressing operation, and thus the sensor does not receive a signal during this tremor, resulting in an error. Likewise, the detection pin opposing the pilot hole at the normal feed position is There is a way to penetrate into the pilot hole so that the detection pin can be detected by a different change voltage depending on whether or not the detection pin is in contact with the workpiece, but this is a complicated configuration, which requires excessive manufacturing costs, causes frequent failures, and requires additional time for detection. There are many problems such as lowering the work efficiency.
본 발명은 상술한 종래에 제반 문제점들을 해결하고자 금형 설계시부터 지정되는 위치에 센서를 간단한 설치 고정해 주면 셋팅작업이 완료되고 또한 감지능력이 우수하며, 간단한 구조로 제조경비와 오작동을 줄일 수 있고, 작업능률을 향상시켜 줄수가 있는 순차 이송 프레스기의 가공품 정위치 감지장치를 제공함에 그 목적이 있다.The present invention is to solve the above-mentioned problems in the prior art, if the simple installation and fixing the sensor at the designated position from the mold design is completed, the setting work is completed, and also excellent detection ability, simple structure can reduce the manufacturing cost and malfunction The object of the present invention is to provide a workpiece position detection device of a sequential transfer press which can improve work efficiency.
상기한 목적달성을 위하여 본 발명은 금형 설계시 파일럿핀(pilot pin)을 고정하기 위하여 하부금형이 갖는 다수의 금형홀 중 어느 한 금형홀에 고정핀을 통하여 제어기와 접속되는 센서를 부설하여 가공품의 순차이송시 상기 가공품의 핀공을 통하여 정확한 이송여부를 감지토록 한 것이다.In order to achieve the above object, the present invention is to install a sensor connected to the controller through a fixing pin in any one of the plurality of mold holes of the lower mold in order to fix the pilot pin in the mold design of the workpiece During the sequential transfer, it is to detect whether the correct transfer through the pin hole of the workpiece.

본 발명은 다수의 리프트가이드(2)를 따라 순차적으로 이송되는 가공품(4)의 핀공(6)과 대향되는 위치에 파일럿핀(pilot pin)(8)을 연결고정하기 위하여 금형설계시 하부금형(10)에 형성되는 여러개의 금형홀 중 첫 피치의 금형홀을 제외한 어느 한 금형홀에 파일럿핀(8)을 대신하여 내측에는 나선이 형성된 지지관 (12)을 강제 삽입 고정하고, 상기 지지관(12)에는 그 상부로부터 센서(14)가 내설되고 상기 센서(14)는 통공을 통하여 직상부로 노출되게 한 고정핀(16)을 나사결합고정한다.The present invention provides a lower mold during mold design to connect the pilot pin (8) to a position opposite to the pin hole (6) of the workpiece (4) sequentially transported along the plurality of lift guides (2) 10) Force insertion and fixation of a support tube 12 having a spiral formed therein in place of the pilot pin 8 in any one of the plurality of mold holes formed in the mold hole except for the first pitch. 12, the sensor 14 is built in from the top and the sensor 14 is screwed to the fixing pin 16 to be exposed to the upper portion through the through hole.
상기에 있어 하부금형이 갖는 다수의 금형홀 중 첫피치의 초기 금형홀에는 핀공(6)을 천공하기 위한 펀치가 연결고정되므로 초기 금형홀에는 센서(14)를 갖도록 할 수가 없고, 또 가공품(4)은 이송중 갈수록 큰 폭으로 떨림이 주어지게 되므로 고정핀(16)은 가급적 초기 금형홀 인근의 금형홀에 설치고정해 주는 것이 바람직하다.In the above, since the punch for drilling the pin hole 6 is fixed to the initial mold hole of the first pitch among the plurality of mold holes of the lower mold, the initial mold hole cannot have the sensor 14, and the workpiece (4) Since tremors are given with a greater width during transport, the fixing pin 16 is preferably fixed to the mold hole near the initial mold hole.
또한 센서(14)가 내설된 고정핀(16)은 가급적 일반 파일럿핀(8)과 같은 외형으로 형성하여 파일럿핀으로서의 역할을 겸할 수 있도록 한다.In addition, the fixing pin 16 in which the sensor 14 is built is preferably formed in the same shape as the general pilot pin 8 so as to serve as a pilot pin.
미 설명부호 (18)은 세트볼트, (20)은 커넥터이다.Reference numeral 18 is a set bolt, and 20 is a connector.
본 발명은 금형설계시 금형홀을 갖게 되고 또 선택된 금형홀에 파일럿핀을 대신하여 센서(14)가 내설된 고정핀(16)을 지지관(12)에 체결고정해 주면 되므로 가공품(14)이 갖는 순차적인 이송거리에 따른 별도의 위치 선정없이 간단하고 신속하게 설치해 줄 수가 있다.The present invention is to have a mold hole in the mold design, and in addition to the pilot pin in the selected mold hole, the fixing pin 16 in which the sensor 14 is built is fastened and fixed to the support tube 12, so that the workpiece 14 is It can be installed simply and quickly without selecting a separate position according to the sequential transfer distance.
또한 프레싱작업시 피더에 의해 순차적으로 이송되는 가공품의 이송거리가 피치 간격과 일치할 경우 어느 한 파일럿핀을 대신하는 고정핀(16)의 센서(14)는 통공을 통하여 그 직상부에 위치하는 가공품(4)의 핀공(6)에 의해 입광 상태가 되므로 정상적인 프레싱작업이 순차적으로 이루어지게 된다.In addition, the sensor 14 of the fixed pin 16 to replace any one of the pilot pin when the conveying distance of the workpiece sequentially conveyed by the feeder during the pressing operation coincides with the pitch interval, the workpiece located directly above the through Since the light enters the light state by the pin hole 6 in (4), the normal pressing operation is performed sequentially.
그러나 피더에 의한 가공물의 이송시 그 이송거리가 주어진 피치간격과 일치하지 못할 경우 피치간격과 같은 간격을 갖는 가공품(4)의 각 핀공(6)은 파일럿핀(8)과는 물론 센서(14)가 내설된 고정핀(16)과도 어긋나 가공품(4)이 센서(14)를 차광하게 되므로, 이를 감지한 제어기는 기계작동을 정지시켜 주게 된다.However, when the feed distance of the workpiece by the feeder does not coincide with the given pitch interval, each pin hole 6 of the workpiece 4 having the same interval as the pitch interval is not only the pilot pin 8 but also the sensor 14. Since the workpiece 4 is blocked by the fixed pin 16, which is built-in, and the sensor 14 blocks the sensor 14, the controller that detects this stops the operation of the machine.
따라서 파일럿핀(8)을 연결고정해 주기 위하여 금형설계시 하부 금형(10)이 필수적으로 갖는 금형홀 중 어느 한 금형홀에 파일럿핀을 대신하여 센서(14)를 갖도록 하므로서 금형설계시 금형홀의 위치 선정이 잘못 되거나 또 다른 외적인 문제가 없는 이상 상시 정확한 감지능력을 발휘하게 된다.Therefore, in order to secure the connection of the pilot pin 8, the position of the mold hole during the mold design is provided by having the sensor 14 in place of the pilot pin in any one of the mold holes that the lower mold 10 essentially requires during the mold design. As long as there is no wrong selection or other external problem, accurate detection will be performed at all times.
이상과 같이 본 발명은 하부금형의 설계시 필수적으로 갖는 여러개의 금형홀 중 어느 한 금형홀에 파일럿핀을 대신하여 설치해 주면 되므로 설치시 별다른 번거로움이나 어려움없이 간단하고 신속하게 설치해 줄 수가 있고, 또 금형홀에 강제삽입되는 지지관(12)과, 상기 지지관(12)에 체결고정되는 고정핀(16) 및 센서(14)로 구성되므로 구조가 간단하여 제조경비를 절감할 수가 있고 고장발생을 줄일수가 있으며, 프레싱작업시에도 가공물(4)이 이송되어온 순간 오작동 여부를 곧바로 감지하게 되므로 작업능률이 향상되고 피치간격에 따라 갖는 여러 개의 파일럿핀 중 어느 한 파일럿핀을 대신하여 위치하게 되므로 상시 오작동의 우려없이 정확한 감지능력을 발휘할 수가 있는 유용한 발명인 것이다.As described above, the present invention may be installed in place of a pilot pin in any one of a plurality of mold holes that are essential in designing a lower mold, so that the installation can be easily and quickly installed without any hassle or difficulty. It consists of a support tube 12 forcibly inserted into a mold hole, a fixing pin 16 and a sensor 14 fastened to and fixed to the support tube 12, so that the structure is simple, so that manufacturing cost can be reduced and failure occurs. In the pressing operation, the workpiece 4 is immediately detected whether or not a malfunction occurs at the time of conveying, thus improving work efficiency and always malfunctioning because it is located in place of one of several pilot pins according to the pitch interval. It is a useful invention that can exhibit accurate sensing ability without concern.
