PROBLEM TO BE SOLVED: To provide a container conveyor unit capable of more surely detecting an abnormality of ejection pressure of a nozzle.SOLUTION: A container transfer device 11 includes: a star wheel 11A rotating while holding a plurality of bottles 18 on an outer circumferential part thereof; a plurality of nozzles 20 moving in synchronism with the bottles 18 to inject a fluid into the bottles 18; a pressure sensor 30 located opposed to the outer circumferential part of the star wheel 11A to measure the fluid ejection pressure of the nozzles 20; and nozzle ejection state detecting means 45 to detect the abnormality in ejection pressure on the basis of values measured by the pressure sensor 30. The nozzle ejection state detecting means 45 includes: a moving average processing unit 451 for performing moving average processing of the measured values; and a determination unit 452 for determining whether the ejection pressure of the nozzle 20 is normal or abnormal on the basis of the processing result by the moving average processing unit 451. |
