Abstract

본 발명은 크레인 저울의 중량감지에 의한 경보음 발생방법 및 그 장치에 관한 것으로 특히, 기존의 크레인 저울에 경보음 발생기를 부가시키고, 마이컴내에는 1회주탕중량, 상한중량, 하한중량 및 예비설정중량등을 설정기억시켜 연속주탕 주입작업과 같이 임의로 설정한 계량치 만큼이 순차적으로 감소될때 자동감산 되도록 함과 동시에 매 주탕주입시마다 동일한 예비설정중량치에서 경보음 발생기를 작동시키는 프로그램을 입력시켜 주므로서 주탕작업시 작업자가 용탕의 중량 변화를 시각 및 청각을 통해 인식할 수 있어 주탕주입량을 서서히 줄여주므로서 과다한 주입에 의한 제품의 생산원가 상승이 방지되고, 동시에 매 주입시마다 동일한 예비설정중량에서 경보음이 발생되어 1회주탕중량이 되면 정지되므로서 제품의 생산성이 향상되어 질 좋은 주형제품을 다량으로 생산해낼 수 있는 것이다.The present invention relates to a method and a device for generating an alarm sound by detecting the weight of a crane scale, and in particular, adding an alarm sound generator to an existing crane scale, a single pouring weight, an upper limit weight, a lower limit weight and a preset setting in the microcomputer. Since the weight is set, the program automatically operates when the weight is set to decrease automatically, such as continuous pouring, and the alarm sound generator is operated at the same preset weight at every pouring. During the pouring operation, the operator can recognize the weight change of the molten metal by sight and hearing, and gradually reduce the pouring amount, thereby preventing the increase in production cost of the product due to excessive injection, and at the same time, alarming at the same preset weight at each injection When sound is generated and stops at the weight of one pouring, the productivity of the product can be improved. Is that you can pull off a production mold products in large quantities.
