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.

Cap inspection apparatus

A bottle inspection apparatus has an inspection stand and sorter for sorting defective plastic bottles from conforming bottles. The inspection stand has an extendible rod. A conical shaped nozzle is mounted at the end of the rod. The conical nozzle seals itself against a bottle aperture when extended for a predetermined amount of time. A low pressure air stream is operably connected to the nozzle and passes through the nozzle and into the inspected bottle. A pressure sensitive switch means is operably connected to the low pressure air stream. A blocking solenoid valve is operably attached to the pressure sensitive switch means and controls a high pressure air stream sorter. The pressure switch is actuated when a sufficiently high pressure is built up within the bottle within the predetermined limited amount of time the conical nozzle is sealing the bottle aperture. The blocking solenoid is deactivated when the pressure sensitive switch means is actuated. The high pressure air stream passes through the solenoid valve when the solenoid valve is deactivated. The air stream sorter, when activated, directs a conforming bottle onto a conveyor. A holding relay is operably attached to the solenoid valve circuit to maintain required information concerning the pressure build-up in an inspected bottle until the bottle is sorted by the high pressure air stream sorter.
