Cap inspection apparatus

摘要

A cap inspection apparatus has an inspection stand and sorter for sorting defectively capped bottles from properly capped bottles. The inspection stand has a nozzle with a rearward flat bottom surface and a front inclined bottom surface inclined upwardly from the rear bottom surface. An air passage extends through the rear bottom surface. A low pressure air stream is operably connected to the air passage and passes through the nozzle. A pressure sensitive switch means is operably connected to the low pressure air stream. A solenoid valve is operably attached to the pressure sensitive switch means and controls a high pressure air stream operably connected to an air operated cylinder and rod. An ejection block is mounted at the end of the extendible rod for pushing defectively capped bottles.
