AIR CONSUMPTION CALCULATING DEVICE, SPINNING MACHINE, SPINNING SYSTEM, AND METHOD FOR CALCULATING AIR CONSUMPTION

摘要

A collective control unit (air consumption calculating device) 93 includes an obtaining unit 93b and a calculating unit 93c, and executes a method for calculating an air consumption. The obtaining unit 93b obtains operation information of an air spinning device 9 configured to inject air through a spinning nozzle to generate a swirling airflow to produce a spun yarn from a fiber bundle, the operation information including a time period in which the air is injected from the spinning nozzle. The calculating unit 93c calculates an air consumption of a spinning machine 1 that includes the air spinning device 9, based on the operation information of the air spinning device 9 obtained by the obtaining unit 93b.
