Relates to a device.

제1도는 종래 스트립(strip)의 두께편차를 측정하는 방법을 보여주는 도면, 제2도는 종래의 라인정지 회로도로서, 도면부호 1은 페이오프릴(pay off reel), 2와 10은 핀치롤, 3은 압연롤을 각각 나타내고, 4는 주엑스레이 표시판넬이며, 5는 엑스레이 두께검출기이다. 또한 도면부호 6, 7은 각각 절단기, 보조 엑스레이 표시판넬이고, 8은 종합운전판넬이며, 9은 프린터이다. 그리고 도면 부호 11은 권취릴, 12은 스트립을 각각 나타낸다.1 is a view showing a method of measuring thickness deviation of a conventional strip, and FIG. 2 is a conventional line stop circuit diagram, in which reference numeral 1 denotes a pay off reel, 2 and 10 pinch rolls, and FIG. Silver rolls are respectively shown, 4 is a main X-ray display panel, and 5 is an X-ray thickness detector. Reference numerals 6 and 7 denote cutters and auxiliary X-ray display panels, 8 denotes general operation panels, and 9 denotes printers. Reference numeral 11 denotes a winding reel and 12 denotes a strip.

제1도 및 제2도에 도시한 종래방법에 의한 스트립의 두께편차 측정은 먼저 수요자가 요구하는 스트립의 두께한계치를 보조엑스레이 표시판넬(7)에 있는 버턴(BN)을 조작하여 셋팅한 후 스트립(12)의 두께를 측정하게되고, 스트립(12)의 두께가 엑스레이 두께검출기(5)에서 측정되어 수요자가 요구하는 두께한계치를 벗어나게 되면, 보조엑스레이 표시판넬(7)에 있는 램프(L/P)가 점등됨과 공시에 부저(B/Z)가 울리도록 되어 있다. 따라서 램프(L/P)가 점등되고 부저(B/Z)가 울리면 스트립(12)의 두께불량으로 판정하여 종합운전판넬(8)에 있는 라인정지스위치(SW)를 조작 라인을 정지시키고 다음 작업순서(두께불량부분의 절단 및 재작업)로 연결되게 되나, 일반적으로 주엑스레이 표시판넬(4)은 주운전실에 설치되고 있어서 작업자로부터 멀리 떨어져 있고, 주운전실이 무인화되어 있으며, 보조엑스레이 표시판넬(7)도 작업자로부터 멀리 떨어져 있어서, 통장적으로는 작업자(검사자)가 소재투입후 엑스레이 두께검출기(5)를 통과한 스트립을 권취릴(11)에 권취하면서 외관검사(표면, 폭, 두께, 귀불량등)를 눈과 귀로서 행하게 된다. 이러한 시각과 청각에 의한 검사에서 스트립의 두께가 수요자가 요구하는 허용치를 벗어날 때에 검사자는 라인을 수동으로 정지스위치를 조작하여 정지시키고 스트립의 불량발생지점을 절단기(6)까지 후진시켜 절단처리하게 되며, 절단이 불가능한 것은 재작업하게 된다.To measure the thickness deviation of the strip by the conventional method shown in FIGS. 1 and 2, first, the thickness limit of the strip required by the consumer is set by manipulating the button BN on the auxiliary X-ray display panel 7 and then the strip. When the thickness of the strip 12 is measured and the thickness of the strip 12 is measured by the X-ray thickness detector 5 to deviate from the thickness limit required by the consumer, a lamp (L / P) on the auxiliary X-ray display panel 7 is displayed. ) Lights up and buzzer (B / Z) sounds at the time of publication. Therefore, when the lamp (L / P) lights up and the buzzer (B / Z) rings, it is determined that the thickness of the strip 12 is poor, and the line stop switch (SW) in the overall operation panel (8) stops the operation line and the next operation. The main x-ray display panel 4 is installed in the main cab and is far from the operator, the main cab is unmanned, and the auxiliary x-ray display panel ( 7) is also far from the operator, and in general, the operator (inspector) wounds the strip passing through the X-ray thickness detector 5 after the material is inserted into the winding reel 11 to inspect the appearance (surface, width, thickness, ear). Defects) as eyes and ears. When the thickness of the strip is beyond the tolerance required by the consumer in the visual and audit inspection, the inspector stops the line by manually operating the stop switch, and reverses and cuts the spot where the defect occurs to the cutter 6. If it is impossible to cut, it will be reworked.

이와 같이 종래 스트립의 두께검사는 검사자의 시각과 청각에 의해 이루어지기 때문에 불량발생시 라인의 정지가 지연되어 시간이 많이 소요되는 결점이 있고, 두께불량이 조기발견이 불가능하여 스트립의 후진 량이 많을 뿐만 아니라 재작업으로 인한 이중작업이 많아 작업시간의 낭비가 심하다고 하는 결점이 있었다.As described above, the thickness test of the conventional strip is performed by the inspector's vision and hearing, and thus, the defect of the line is delayed when the defect occurs, which takes a long time. There was a drawback that a lot of double work due to rework was a waste of working time.

또한 검사자의 부주의로 두께불량을 확인하지 못하게 되면, 두께가 불량한 제품이 그대로 수요자에게 공급되게 되어 수요자의 불만사항으로 되고 심한 경우 크레임(claim)처리되는 문제점도 있었다.In addition, when the thickness failure due to careless inspection of the inspector, the poor thickness of the product is supplied to the consumer as it is a complaint of the consumer, and in severe cases, there was a problem (claim).

본 고안은 상기한 종래 스트립의 두께검사가 갖는 제반 문제점을 해결하고 결점들을 제거하고자 안출한 것으로, 스트립의 두께편차를 자동으로 측정하여 두께가 불량한 지점을 자동으로 검출함으로써 짧은 시간에 많은 제품의 두께를 검사처리할 수 있는 두께편차를 자동측정장치를 제공함에 그 목적이 있다.The present invention solves all the problems of the thickness test of the conventional strip and solves the defects, and automatically measures the thickness deviation of the strip and automatically detects the point where the thickness is poor, thereby reducing the thickness of many products in a short time. The purpose is to provide an automatic measuring device for the thickness deviation that can be inspected.

상기한 목적을 달성하기 위한 본 고안 두께편차 자동측정장치는 전원공급부(PS)에 리미트스위치(K2, K3)를 병렬로 연결하고, 리미트스위치(K2, K3)에 릴레이(K1)를 연결함과 더불어 타일릴레이(Tm)를 연결구성하여 스트립(strip)의 두께 불량시점에서 릴레이(K1)의 동작에 의한 릴레이스위치(SWk1)의 오픈 라인을 자동으로 정지시키고, 타임릴레이(Tm)에 의한 카운터회로의 동작으로 릴레이 스위치(SWk1)오프후 스트립의 진행량이 카운트되므로 스트립의 두께불량지점을 정확하게 자동으로 측정할 수 있음을 특징으로 한다.In order to achieve the above object, the present invention has an automatic thickness deviation measuring device. The limit switches K 2 and K 3 are connected in parallel to the power supply unit PS, and the relay K 1 is connected to the limit switches K 2 and K 3 . ) And the tile relay (Tm) connected to automatically stop the open line of the relay switch (SW k1 ) by the operation of the relay (K 1 ) at the time of the thickness of the strip (strip), the time relay By the operation of the counter circuit (Tm), the amount of progress of the strip is counted after the relay switch SW k1 is turned off, so that the thickness defect point of the strip can be accurately and automatically measured.

이하, 첨부도면을 참조하여 본 고안의 작용 및 효과를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the operation and effect of the present invention.

제3도는 본 고안 두께편차 자동측정장치를 사용하여 스트립의 두께편차를 측정하는 과정을 나타내 보인 도면으로서, 제1도와 상이한 점은 주엑스레이 표시판넬(4)과 보조엑스레이 표시판넬(7)에 램프(L/P)와 부저(B/Z)가 없고 대신에 릴레이(K1)와 타임릴레이(Tm)가 설치되어 있는 점과 종합운전판넬(8)에 카운터기(B1)가 설치되어 있다는 점이다.3 is a view showing a process of measuring the thickness deviation of the strip by using the thickness deviation automatic measuring device of the present invention, the difference between the first and the primary X-ray display panel 4 and the auxiliary X-ray display panel (7) There is no (L / P) and buzzer (B / Z), instead relay (K 1 ) and time relay (Tm) are installed, and counter machine (B 1 ) is installed in the integrated operation panel (8). to be.

따라서 스트립(12)의 두께측정시 스트립(12)의 두께가 엑스레이 두께검출기(5)에서 측정되어 미리 셋팅되어 있는 수요자가 요구하는 두께 한계치를 벗어나게 되면, 종래와 같이 종합운전판넬(8)의 라인정지스위치버턴(SW)를 조작하지 않아도 자동으로 라인이 정지할 수 있도록 주엑스레이 표시판넬(4)에 전원공급부(PS)를 설치함과 더불어 리미트 스위치(K2, K3)와 릴레이(K1) 및 타임릴레이(Tm)를 제4도에 도시한 바와 같은 회로도를 구성하여 내장시키고 약 30m거리의 종합운전판넬(8)의 자동정지 조작용 스위치판(B2)까지 배관을 이용한 배선을 매설하여 연결시켜서 이루어진 본 고안 두께 편차 자동측정장치로 스트립의 두께편차 측정시 엑스레이 두께 검출기(5)에서 측정된 스트립(12)의 두께가 버턴(BN)의 조작으로 미리 셋팅되어 있는 수요자가 요구하는 두께를 벗어나게 되면, 제4도에 도시한 리미트스위치(K2, K3)중 어느 하나가 온(ON)되게 되므로 릴레이(K1)가 동작하게 되고, 릴레이(K1)의 동작으로 릴레이스위치(SWk1)가 오프되어 라인에 인가되는 전원이 차단되게 되므로 제3도에 도시한 라인의 운행이 정지하게 된다.Therefore, when the thickness of the strip 12 is measured in the X-ray thickness detector 5 when the thickness of the strip 12 is out of the thickness limit required by the user who is set in advance, the line of the general operation panel 8 as in the prior art The power supply unit PS is installed on the main display panel 4 so that the line can be automatically stopped without operating the stop switch button SW. In addition, the limit switch (K 2 , K 3 ) and the relay (K 1) ) And time relay (Tm) by constructing a circuit diagram as shown in FIG. 4 and embedding wiring using piping to the switch plate (B 2 ) for automatic stop operation of the total operation panel (8) at a distance of about 30m. When the thickness deviation of the strip is measured, the thickness of the strip 12 measured by the X-ray thickness detector 5 is preset by the operation of the button BN. When causing a departure from the to the, the fourth diagram the limit switch shown in (K 2, K 3) of the so either be one-on (ON) and to a relay (K 1) operation, the relay switch to the operation of the relay (K 1) (SW k1 ) is turned off and the power applied to the line is cut off, so that the operation of the line shown in FIG. 3 is stopped.

그러나 릴레이스위치(SWk1)가 오프되어 라인에 인가되는 전원이 차단되어도 라인스피드(linek speed)즉, 스트립(12)의 진행속도가 고속(300m/min)인 관계로 스트립(12)은 즉시 정지할 수 없다. 그런데 본 고안은 리미트스위치(K2, K3)중 어느 하나가 온(ON)되게 되면, 릴레이(K1)와 타임릴레이(Tm)가 동시에 동작하게 되므로 타임릴레이(Tm)의 동작으로 제6도에 도시한 카운터회로가 동작하여 라인정지동작 후 진행한 스트립(12)의 거리를 카운트하여 종합운전판넬(8)상의 카운터기(B1)에 제5(b)도에 나타낸 바와 같이 나타내게 된다.However, even if the relay switch SW k1 is turned off and the power applied to the line is cut off, the strip 12 immediately stops due to the line speed, that is, the moving speed of the strip 12 is 300 m / min. Can not. However, according to the present invention, when one of the limit switches K 2 and K 3 is turned on, the relay K 1 and the time relay Tm are operated at the same time, and thus the sixth operation is performed by the time relay Tm. The counter circuit shown in FIG. 10 operates to count the distance of the strip 12 that has progressed after the line stop operation, and is shown in the counter machine B 1 on the general operation panel 8 as shown in FIG. 5 (b).

따라서 카운트양 만큼 스트립(12)을 후진시키는 방법으로 스트립(12)의 두께불량 부위를 단시간에 정확하게 알 수 있게 되므로 두께불량을 부위를 절단처리 하거나 제작업을 손쉽게 할 수 있다.Therefore, the thickness 12 of the strip 12 can be accurately known in a short time by a method of reversing the strip 12 by the count amount, so that the thickness can be easily cut or processed.

한편, 카운터기(B1)에는 리셋트 스위치(RS)를 설치하여 카운트양을 필요에 따라 리셋트시킬 수 있고. 종합운전판넬(8)상에는 제5(c)도에 나타낸 바와 같이 자동·수동스위치와 부저스위치등으로 이루어진 자동정리 조작용 스위치판(B2)을 설치하여 종합운전이 가능하며, 보조엑스레이 표시판넬(7)에 잡음방지필터(NF)를 설치하여 신호처리의 설비에 대한 잡음을 제거할 수 있으므로 제4도 및 제6도에 도시한 회로가 정확하게 동작하게 된다.On the other hand, a counter switch B 1 is provided with a reset switch RS to reset the count amount as necessary. On the integrated operation panel 8, as shown in FIG. 5 (c), a comprehensive operation is possible by installing a switch panel B 2 for automatic clearance operation, which consists of automatic and manual switches, a buzzer switch, and the like. The noise suppression filter (NF) can be installed at (7) to remove the noise of the equipment for signal processing, so that the circuits shown in FIGS. 4 and 6 operate correctly.

상기한 바와 같이 작용하는 본 고안 두께편차 자동측정장치는 검출된 스트립의 두께값이 요구공차를 벗어날때 운전자가 수동으로 라인을 정지시키지 않아도 라인이 자동으로 정지되며, 라인의 정지동작 후 라인이 완전히 정지할 때까지 진행한 스트립의 양이 카운터에 의해 자동으로 카운팅되어 스트립의 두께불량 부위를 짧은 시간에 정확하게 알 수 있으므로, 두께불량 부위를 찾기 위하여 프린트챠트지를 확인하거나 재검사하는 등 시간적인 낭비와 인건비를 줄일 수 있는 장점을 갖는다.The thickness deviation automatic measuring device of the present invention, which operates as described above, automatically stops the line even if the driver does not stop the line manually when the detected thickness value of the strip exceeds the required tolerance. The amount of strip progressed until the stop is automatically counted by the counter, so that you can accurately know the thickness of the strip in a short time. Has the advantage of reducing.
