Description

금속 시트재 절단장치 및 그 절단방법Metal sheet cutting device and its cutting method

본 발명은 금속 시트재 절단장치 및 그 절단방법에 관한 것으로, 보다 상세하게는 인코더와 딥센서를 이용한 자동연산처리장치를 설치하여 절단유효면의 간격이 다른 금속 시트재(제품)를 크기가 동일하게 한 장씩 정밀하게 절단하고 이송속도의 자동조정, 이중절단을 방지하여 생산성을 높일 수 있는 금속 시트재 절단장치에 관한 것이다.The present invention relates to a metal sheet material cutting device and a cutting method thereof, and more particularly, by installing an automatic operation processing device using an encoder and a dip sensor, the size of the metal sheet material (product) having different cutting effective surfaces is the same. The present invention relates to a metal sheet cutting device that can increase productivity by cutting precisely one by one, automatically adjusting the feed rate, and preventing double cutting.

도 1은 종래의 금속 시트재인 섀도우 마스크의 절단장치를 개략적으로 나타낸 개략도, 도 2는 섀도우 마스크(10)의 절단공정을 나타낸 설명도이다. 이 도면을 참조하면, 에칭 가공처리의 연속된 섀도우 마스크(10)를 반출시키는 반출롤러(20)와, 이 반출롤러(20)에 의하여 반출된 섀도우 마스크(10)를 이송시키는 모터(72)를 가지는 이송롤러(70)와, 섀도우 마스크 제품과 제품 사이의 절단 유효면(12)을 감지하여 절단위치를 결정하는 절단감지 센서를 포함하는 절단감지부(30), 절단시 반송되는 섀도우 마스크(10)를 축적하는 딥바를 가지는 딥부(40), 철판 처짐에 의한 딥바 상승, 하강시 이송을 제어하는 상/하한 감지부(52),(54), 이송 정지된 섀도우 마스크(10)의 절단 유효면(12)을 절단하는 절단칼날을 가지는 절단부(60)로 구성된다.1 is a schematic diagram schematically showing a cutting device of a shadow mask which is a conventional metal sheet material, and FIG. 2 is an explanatory view showing a cutting process of the shadow mask 10. Referring to this figure, the carrying out roller 20 which carries out the continuous shadow mask 10 of an etching process, and the motor 72 which conveys the shadow mask 10 carried out by this carrying roller 20 are conveyed. The branch detecting portion 30 includes a feed roller 70, a cutting detection sensor for detecting a cutting effective surface 12 between the shadow mask product and the product, and determining a cutting position, and the shadow mask 10 conveyed during cutting. Cutting effective surface of the dip part 40 having a deep bar that accumulates), the upper / lower limit detection parts 52 and 54 that control the transfer of the dip bar due to deflection of the steel plate, and the transfer when descending. It consists of the cutting part 60 which has the cutting blade which cuts (12).

이와 같이 구성된 종래의 섀도우 마스크의 절단장치에 의한 절단방법은 다음과 같다.The cutting method of the conventional shadow mask cutting device configured as described above is as follows.

도 3은 종래의 금속 시트재 절단장치의 절단공정의 흐름을 나타낸 흐름도이다. 도 1의 반출롤러(20)에 의해 반출된 연속된 섀도우 마스크(10)가 이송롤러(70)에 의해 이송되면 절단감지부(30)의 절단감지 센서가 도 2의 절단 유효면(12), 즉 비투광부를 감지하고, 설정된 일정 시간 후 절단부(60)의 절단칼날이 작동하여 금속소재를 절단하므로서 절단된 섀도우 마스크(100)가 만들어진다.3 is a flowchart showing a flow of a cutting process of a conventional metal sheet cutting device. When the continuous shadow mask 10 carried out by the transport roller 20 of FIG. 1 is transported by the transport roller 70, the cutting detection sensor of the cutting detection unit 30 is cut effective surface 12 of FIG. 2. That is, after detecting a non-transmissive part, the cutting blade of the cutting part 60 is operated to cut the metal material by the cut shadow mask 100 is made.

절단 완료후 철판은 재이송되어 위의 동작을 되풀이하고, 횟수가 거듭하면서 딥부(40)의 딥바가 상승하면 상한감지센서(52)가 작동하여 철판 이송이 정지된다.After the cutting is completed, the iron plate is re-transmitted to repeat the above operation, and if the number of times the dip bar of the dip unit 40 rises, the upper limit detection sensor 52 is activated to stop the iron plate transfer.

그 후 철판이 처짐에 따라 딥바를 하강하면 하한 감지센서(54)가 작동하여 철판 이송이 재개되어 위의 동작이 반복된다.Then, when the dip bar is lowered as the iron plate sag, the lower limit sensor 54 is operated to resume the transfer of the iron plate, and the above operation is repeated.

그런데, 상기 구조로 된 종래의 금속 시트재 절단장치 및 그 절단방법은, 연속된 섀도우 마스크(10)가 상기 이송롤러(70)에 의해 이송되면 절단칼날에 의해 절단되는방식을 채택하고 있고, 절단감지부(30) 상의 고정된 절단 감지센서가 절단 유효면(12)을 감지하면 섀도우 마스크(10)의 이송이 정지되고 절단을 하는 데, 도 2와 같이 절단 유효면(12)의 넓이가 다를 경우 절단된 섀도우 마스크(100)의 크기가 달라져서 적재될 때 긁힘, 꺽임이 발생되어 불량이 된다.By the way, the conventional metal sheet material cutting device and the cutting method having the above structure adopts a method in which the continuous shadow mask 10 is cut by a cutting blade when transferred by the feed roller 70, and cutting When the fixed cutting detection sensor on the sensing unit 30 detects the cutting effective surface 12, the transfer of the shadow mask 10 is stopped and the cutting is performed. As shown in FIG. 2, the width of the cutting effective surface 12 is different. In this case, when the size of the cut shadow mask 100 is changed and is loaded, scratches and bending occur and become a defect.

또한 도 1에서 절단이 되풀이되면서 반출속도보다 이송되는 속도가 빠르므로 섀도우 마스크(10)의 처짐이 감소하여 딥부(40)의 딥바가 상승, 상한 감지센서(52)가 작동하여 이송이 정지한다. 이 때, 절단부(60)의 절단 감지센서와 동시 작동하게 될 경우 그 중 절단이 발생하여 제품 절단 유효면이 아닌 제품을 절단하여 불량이 발생한다.In addition, since the cutting is repeated in FIG. 1 and the feeding speed is faster than the discharging speed, deflection of the shadow mask 10 is reduced, the dip bar of the dip part 40 is raised, and the upper limit detection sensor 52 is operated to stop the feeding. At this time, when it is operated simultaneously with the cutting detection sensor of the cutting unit 60, the cutting occurs among them to cut the product, not the effective cutting surface of the product occurs.

따라서, 본 발명의 목적은 인코더와 딥센서를 채택하여 금속소재의 절단 유효면의 간격이 다른 금속시트재를 크기가 동일하게 절단하고 이송속도를 자동으로 조정하며 2중절단을 방지하여 절단공정의 효율화를 기할 수 있는 금속 시트재 절단장치를 제공함에 있다.Therefore, an object of the present invention is to adopt an encoder and a dip sensor to cut the metal sheet material having different intervals of the effective surface of the metal material in the same size, to adjust the feed rate automatically and to prevent the double cutting of the cutting process An object of the present invention is to provide a metal sheet cutting device capable of improving efficiency.

또, 본 발명의 다른 목적은 인코더와 딥센서를 채택하여 금속소재의 절단 유효면의 간격이 다른 금속시트재를 크기가 동일하게 절단하고 이송속도를 자동으로 조정하며 2중절단을 방지하여 절단공정의 효율화를 기할 수 있는 금속 시트재 절단방법을 제공함에 있다.In addition, another object of the present invention is to adopt an encoder and a dip sensor to cut the metal sheet material having different intervals of the effective surface of the metal material in the same size, to adjust the feed rate automatically and to prevent the double cutting cutting process It is to provide a metal sheet material cutting method that can improve the efficiency.

It is a flow chart.

본 발명에서는 종래의 장치에 절단 유효면(12)의 중간을 절단하도록 이송거리 감지용 인코더(80)를 설치하고, 이중절단을 방지하기 위하여 항상 일정한 딥을 유지하게 하는 딥 센서(90)를 설치하고 있다.In the present invention, the feed distance sensing encoder 80 is installed to cut the middle of the cutting effective surface 12 in the conventional apparatus, and the dip sensor 90 is installed to always maintain a constant dip to prevent double cutting. Doing.

상기 구성을 가지는 본 발명의 금속 시트재 절단장치의 동작은 다음과 같다. 도 5의 흐름도를 참조하면, 먼저 전원을 ON하고, 이송 속도를 설정후 이송 모터를 ON하면 철판 이송이 실행된다, 이 때, 도 3의 절단부(60)의 절단 감지센서와 이송거리 감지용 인코더(80)에 의해 절단 유효면(12)의 간격을 측정하여 기억부에 저장한다. 그리고, 절단부(60)의 절단 감지센서와 이송거리 감지용 인코더(80)에 의해 제품부(투광부)를 감지하여 미리 설정된 거리(L1), 절단 유효면의 간격(L2)의 1/2값을 더한 값(L0), 즉 L1+L2/2=L0를 산출하여 L0 지점에서 이송을 정지하여 절단한다.Operation of the metal sheet material cutting device of the present invention having the above configuration is as follows. Referring to the flowchart of FIG. 5, first, the power is turned on, the feed rate is set, and then the feed motor is turned on to perform the plate feeding. At this time, the cut detection sensor and the feed distance sensing encoder of the cutting unit 60 of FIG. The distance between the cut effective surfaces 12 is measured by 80 and stored in the storage unit. Then, the product detection part (transmitting part) is detected by the cutting detection sensor of the cutting part 60 and the encoder 80 for detecting the distance, and thus the 1/2 value of the distance L1 set in advance and the interval L2 of the effective cutting surface.
