본 고안은 가스용기의 중량을 측정하도록 고안된 것으로서, 특히, 방진효과가 우수하고 정확성이 있도록 하는 가스용기 전용의 측정기에 관한 것이다.The present invention is designed to measure the weight of a gas container, and in particular, relates to a gas container-only measuring device that is excellent in accuracy and accurate in dustproof.
일반적으로, 내용물이 충전된 가스용기와 같은 중량체는 공개특허 83-2224호와 같은 로드셀을 이용한 장치가 사용되고 있다.In general, as a weight body such as a gas container filled with contents, an apparatus using a load cell such as Korean Patent Laid-Open No. 83-2224 is used.
그러나 이러한 장치에서는 다량으로 계속 계측하게 되면 장기간 사용후에는 정밀도가 저하될 우려가 많다.However, in such a device, if the measurement is continued in large quantities, the precision may be degraded after long-term use.
더구나, 가스용기는 금속재이며 인력으로 취급하게 되면 그 하증을 이기지 못하여 부드럽게 다룰수 없다는 것이 문제이다.In addition, the gas container is a metal material and when handled with a manpower is a problem that can not be overcome smoothly because it does not overcome the lower.
즉, 가스용기를 측정기위에 충격적으로 내려 놓거나 또는 끌고다니거나 충돌등이 빈번히 발생되어 중량측 정기의 정밀한 계측도를 떨어트리게 되고 더 나아가서는 관련 부품등을 손상시키는 사례가 잦았던 것이다.In other words, the gas container is shocked to drop or dragged around the measuring device, or the collision occurs frequently, which causes the precision measurement of the weight measuring device to drop, and moreover, the related parts are often damaged.
그러나, 무수한 가스용기를 취급함에 있어서는 위와 같은 거칠게 다루어질 수 밖에 없는 상태이므로 오히려 중량측정기의 대응수단을 생각하게 되는 것이다.However, when dealing with a myriad of gas containers it is a condition that can not be handled roughly as above, rather the countermeasure of the weighing instrument is to be considered.
본 고안은 1. 충전가스용기가 그 하중에 의하여 거칠게 다루어진다는 점.The present invention 1. The filling gas container is roughly handled by the load.
2. 정밀, 정확하게 계측되어야 한다는 점을 중점적으로 고려하여 위의 조건에 부응될 수 있는 합리적 인중량 측정기를 제공하려는데 주목적이 있는 것이다.2. The main objective is to provide a reasonable weighing machine that can meet the above conditions, with the emphasis on precise and accurate measurement.
본 고안의 특징은, 충격을 흡수할 수 있는 방진효과를 갖으며, 측정대와 표시기를 별도로 구분설치하여 가스 용기의 간섭이나 장해를 받지않게 하려는 것으로서 브리지 회로를 사용하여 직류증폭시키고 아나로그신호를 디지탈신호로 바꾸어 컴퓨터에 입력시켜 자동프로그램 전산화처리 시스템으로 할수 있도록 한 증량측정기이다.The feature of the present invention is to have a dust-proof effect that can absorb shocks, and to separately install the measuring table and the indicator so as not to interfere with the gas container by interference and obstacles. It is a weight increaser that converts a digital signal into a computer and inputs it to a computerized automatic program processing system.
이하, 본 고안의 구조 및 작용효과 등을 첨부된 도면과 관련하여 구체적으로 기술하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the structure and effect of the present invention in detail as follows.
제1도는 본 고안의 사시도로서 프레임(F)의 상부에 3단의 로울런 프레이트가 설치된다.FIG. 1 is a perspective view of the present invention, in which three rows of roller run plates are installed on the upper portion of the frame F. As shown in FIG.
즉, 전,후에는 각각 가이드롤러 플레이트(P)(P')가 위치되고 중량에는 게측용 롤러플레이트(R)가 위치된다.That is, the guide roller plate (P) (P ') is positioned before and after, respectively, and the crab side roller plate (R) is positioned in the weight.
상기의 롤러플레이트(R)는 양변의 레일에 다수의 로울러(r)가 평활한 면으로 축 설치되어 있고 이러한 단위를 이루는 전,후 플레이트(P)(P')는, 중앙의 계측플레이트(P)에 비하여 약간 짧은 형태로 되어있다.In the roller plate R, a plurality of rollers r are axially installed on the rails on both sides, and the front and rear plates P and P 'forming such a unit are the central measurement plate P. It is slightly shorter than).
계측플레이트(R)의 저부에는 받침판(Q)이 부착되고 내부의 중앙지점에 로드셋(LOAD CFLL)이 위치되며, 지지판(K)상에 놓여져 있다.The base plate Q is attached to the bottom of the measurement plate R, and the load set LOAD CFLL is located at the center of the inside, and is placed on the support plate K.
지지판(K)은 탄성고무재로 된 마운트(M)에 의하여 받쳐지게 되며, 마운트(M)는 지지판(K)과 프레임(F)에 나사로 고정된다.The support plate K is supported by a mount M made of an elastic rubber material, and the mount M is fixed to the support plate K and the frame F with screws.
로드셋(LCe)은 별도로 취부되는 디지탈표시기(D)와 연결하며, 미세한 신호를 증폭시키는 교류증폭기 회로(1)와, R.C검파회로(3) 및 직류증폭기회로(5)와 A/D컨버터(6)를 연결하되, 로드셋(LCe)에 연결된 발런스회로와 브리지증폭기 전압회로(2) 및 발진기(4)를 상기 R.C검파회로(3)에 연결한다.The load set LCe is connected to a separately mounted digital display D, an AC amplifier circuit 1 for amplifying minute signals, an RC detector circuit 3, a DC amplifier circuit 5, and an A / D converter ( 6), but the balance circuit connected to the load set LCe, the bridge amplifier voltage circuit 2 and the oscillator 4 are connected to the RC detection circuit (3).
A/D컨버터(6)는 마이크로컴퓨터(7)에 연결하고, 인터페이스(8)를 통해 비교기(9)와 콘트롤출력부(10)에 연결하며, 마이크로컴퓨터(7)의 상단은 디지탈클럭부(11)와 프로그램기억식 계산기(12) 및 선형연산기(13)를 연결하고, 하단은 메모리(14)와 표시기(15) 및 키보드(16)를 연결하여 구성한다.The A / D converter 6 is connected to the microcomputer 7, and is connected to the comparator 9 and the control output unit 10 through the interface 8, and the upper end of the microcomputer 7 has a digital clock unit ( 11) and the program memory calculator 12 and the linear operator 13 are connected, and the lower end is configured by connecting the memory 14, the indicator 15 and the keyboard 16.
이와 같이 구성된 본 고안은 도면 제2도와 같이 프레임(F)을 지면에 고정, 착설하여 로울러플레이트(P)(P')(R)가 수평을 유지하도록 하여 가스용기(G)의 중량을 측정하게 되는 것이다.The present invention configured as described above is fixed to the ground (F) on the ground as shown in Figure 2 so that the roller plate (P) (P ') (R) to maintain the horizontal to measure the weight of the gas container (G) Will be.
즉, 가스용기(G)를 전방의 가이드 로울러프레이트(P')에 내려놓으면 최초의 충격을 여기에서 받게되며 그후 가스용기를 이동시키면 로울러(r)에 안내되어 계측용 롤러플레이트(R)에 얹어지게 되면서 하중이 받침판(Q)및 로그셋(LCe)에 전달되고 로드셀(LCe)에 감지된 하중은 별도의 디지탈표시기(D)에 문자로 나타내게 되는 것이다.That is, when the gas container (G) is lowered on the front guide roller plate (P '), the first impact is received here, and when the gas container is moved thereafter, the gas container (G) is guided to the roller (r) and placed on the measuring roller plate (R). As the load is transferred to the support plate Q and the log set LCe, the load sensed by the load cell LCe is displayed on a separate digital display D in letters.
다시말해서, 계측롤러플레이트(R)의 저부에 받침판(Q)이 부착되고, 내부 중앙지점의 로드셋(LCe)에 의해 하중을 받으면 R.C발런스회로에 균형이 깨져 발진기(4)에서 브리지증폭기 전압회로(2)를 통해 공급된 신호에 의해 평형된 상태만큼의 값을 교류증폭기회로(1)로 보내 교류증폭시키고, 증폭된 변위량이 저항검파회로(3)와 발진기(4)의 신호와 믹서되어 검파시켜 다시 직류증폭기회로(5)와 입력되어 증폭시키고 증폭된 아나로그 신호를 마이크로 컴퓨터(7)에 의해 자동프로그램 전산화시스템으로 제어하기 위해 디지탈 신호로 바꾸어주는 A/D컨버터(6)에 입력된다.In other words, when the support plate Q is attached to the bottom of the measurement roller plate R, and the load is applied by the rod set LCe at the internal center point, the RC balance circuit is unbalanced and the bridge amplifier voltage circuit at the oscillator 4 is broken. (2) sends the value equal to the state equilibrated by the signal supplied through the AC amplifier circuit (1) to AC amplification, and the amplified displacement is mixed with the signals of the resistance detection circuit (3) and the oscillator (4) and detected. The A / D converter 6 converts the amplified and amplified analog signal into a digital signal for control by an automatic program computerized system by the microcomputer 7.
입력된 아나로그 신호는 디지탈신호로 바뀌어 마이크로 컴퓨터(7)에 입력되면서 디지탈클럭부(11)와 선형연산기(13)에 의해 프로그램 기억식 계산기(12)로 카운터를 실행하게, 되고 또한 메모리(14)와 표시기(15)로 나타내며, 키보드(16)에 의해 자동화 연산처리가 된다.The input analog signal is converted into a digital signal and input to the microcomputer 7 so as to execute a counter by the program storage calculator 12 by the digital clock unit 11 and the linear operator 13, and the memory 14 ) And an indicator 15, and the keyboard 16 performs automated arithmetic processing.
이때 마이크 컴퓨터(7)는 인터페이스(8)를 통한 비교기(9)에 의해 대응값을 산출함과 동시에 콘톨롤출력부(10)로 신호를 출력하게 제어한다.At this time, the microphone computer 7 controls to output a signal to the control output unit 10 while calculating a corresponding value by the comparator 9 through the interface 8.
이상과 같은 본 고안은 가스용기의 충격이 가이드롤러 플레이트(P')에서 최초로 흡수되고 이동시의 진동은 탄성재의 마운트(M)에서 흡수하게 되므로 로드셋(LCe)에 무리한 충격 및 강압력이 예방되어 계측기의 수명을 배가시킬 수 있는 것이며 특히, 로드셋을 이용한 브리지회로를 전자석으로 디지탈화하여, 중량에 대해 정밀도를 높혀 정확도를 유지하게 되어 결국 중량이 무거운 가스용기(G)로 부터 계측기가 보호되는 가운데 높은 계측효과를 달성할 수 있는 것이다.The present invention as described above is because the shock of the gas container is first absorbed in the guide roller plate (P ') and the vibration during movement is absorbed in the mount (M) of the elastic material, which prevents excessive impact and strong pressure on the rod set (LCe) In particular, it is possible to double the life of the instrument.In particular, the bridge circuit using the rod set is digitalized with an electromagnet, and the accuracy of the weight is increased to maintain the accuracy, while the instrument is protected from the heavy gas container (G). High measuring effect can be achieved.
