Abstract: A nozzle management device includes a plurality of pallets, each of the pallets configured to house a plurality of nozzles; a pallet storage device configured to store the pallets; and a pallet moving device configured to move the pallets.

Abstract: Before using a load cell to measure a load (nozzle load) arising during relative movement between a suction tube and a pipe of a suction nozzle, the suction nozzle and a metal contact tool are moved towards each other by a set load with the metal contact tool contacting the tip section of the suction tube. When the suction tube and the pipe has moved relatively by set amount due to the suction nozzle and metal contact tool being moved towards each other, the nozzle load of the suction nozzle is measured using the load cell. Nozzle load is measured only for a suction nozzle for which relative movement of the suction tube and the pipe has been confirmed, and nozzle load is measured appropriately without damaging the load sensor.

Abstract: An inspection method of a suction nozzle. Air flow rates that flow in multiple reference pipes that have different sectional areas are measured. A proportionality factor between air flow rates and sectional areas of the reference pipes is calculated based on the measured air flow rates of the multiple reference pipes, and the sectional areas of the multiple reference pipes. An air flow rate in a suction nozzle that is an inspection target is measured. The sectional area of the suction nozzle is calculated based on the air flow rate of the suction nozzle and the calculated proportionality factor. The sectional area of the suction nozzle calculated in this manner is substantially fixed even when the pressure of air supplied from an air source fluctuates. The sectional area of the suction nozzle is proportional to the air flow rate that flows in an inner portion of the suction nozzle.
