The online infrared pneumatic ordered arrangement for capsules in aluminum-plastic packaging machine

According to the technique of infrared non-contact detection and pneumatic control, the online ordered arrangement system for capsule packaging is self-designed. Collecting and recognizing the partial image characteristics of the capsule body and its cap, the capsule arrangement online detection and capsule direction turning are realized in capsule aluminum-plastic packaging machine. Considering the inaccuracy and pretermission caused by the jumpiness or incline of capsules, the capsule image characteristics collected by two pairs of infrared photoelectric sensor are processed by added and differential operations, the analogue signal that describes the dimension difference between capsule body and cap is transferred into digital signal. And the accuracy and anti-interference for signal detection are improved. Based on the theory of the sticky wall effect on fluidics, the accelerating and pneumatic overturn mechanism with streamlined slipway for capsules is designed. Utilizing the pulse wide, the velocity and acceleration of capsule are achieved, and the start moment of pneumatic turnover mechanism for any speed of capsule is provided advanced. The capsule is accelerated and turned by the entrainment effect of air fluidics, which improve the accuracy and efficiency of turning, and realize the arrangement of capsule direction.
