用维尼龙袋装物料时,利用气压检测袋口是否打开到应有的程度。在将一定量的糖果等物装入袋子时,要一面由旋转台移动,一面按照以下的顺序进行作业,即取出袋子,打开袋子,填充物料和扎紧袋口等。在这一连续作业中,用气压传感器 FPD 检测维尼龙袋子的开口度。调节器使一定压力的空气从气压传感器的环状喷咀喷出,如果维尼龙袋打开到规定的位置,便使压缩空气反射,并通过检测口输出,然后输入到读出器。在读出器中,被输入的气压信号变换成电信号,这个信号使物料填充器的阀打开,往袋子
When bagged with vinylon, use the air pressure to check if the pocket is open to the extent it is due. When a certain amount of candy and the like is loaded into the bag, the bag is removed by moving the rotary table while removing the bag, opening the bag, filling the material, fastening the bag, and the like, in the following order. In this continuous operation, the opening of the vinylon bag is detected by the air pressure sensor FPD. Regulator to a certain pressure of air from the pressure sensor ring nozzle spout, if the walnut bag opened to the prescribed position, the compressed air is reflected and output through the test port, and then enter the reader. In the reader, the pressure signal is converted into an electrical signal, which signals the material filler valve open to the bag
