Can Integrity Inspection Machine

In this paper, a can integrity inspection machine is presented. This machine is a fusion of different technologies such as Image processing, programmable logic controller (PLC), Human machine interface (HMI) and Actuators with other types of sensors. The electrical and mechanical design of the machine and plc program is illustrated in detail. Generally, inspection of raw materials or products at any stage in production or manufacturing or assembly industries may be done manually using eyes, measuring instruments, or by machines based on laser sensor technology, using probes, weighing scales, etc. Manual process is too slow and meant to test only few batches out of the entire lot which is less effective. Dedicated machines are usually confined to a single type of raw material considering specific property of the component. This option can be expensive when several different raw materials and product at any stage are to be tested at in-feed line. The proposed quality inspection machine is designed and implemented in the PLC lab at KOSEN KMUTT Thailand. The outcomes of the project reveal the feasibility of effectively inspecting the quality of cans. However, occasional shortcomings were observed, attributed to the challenge of detecting minor dents that might evade camera detection.
