Machine Vision Inspection System The inspection machines manufactured by P&S Technology are installed on the production line for inspecting preforms using for PET PET bottles. The inspection and ejection process of machines is automatic and there are variety of machine speed suitable for customer‘s production line speed. Especially PS-21GP series 3 recently having a good sales results provides lots of advantages for custo- mers. The machine‘s maximum speed is 48,000PPH and there is no need to change parts as per changing preform‘s body size because gripper neck handling type is applied to preform handling equipment. Mold number reading or gate cutting device could be equipped as an option inside of inspection system. We say it is two in one system., so customer can save cost and space. This inspection system is mainly designed for rotary type. This system intensively inspect not only preform body but also particle and defect of preform neck ex- ternal. It use the patented ‚mirror tracking system‘ for the bottle body inspected, so customer can inspect whole surface of preform body without blind spot. P&S have another solution to inspect preform. PS- 21PSI Series 1 is haven’t mirror tracking system but applied “line scan camera” technology overcome the limitation by refraction of light of inspection scope. The whole surface of body inspection is guaranteed by 3 line scan cameras located 120 degree each without rotation. The gripper neck handling type on this series is applied to preform handling equipment, so there is no need to change parts.
