ABSTRACT:
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.
