Problems solved by technology
[0004] However, in the above-mentioned configuration, the above-mentioned threshold must be set for each pressure sensor, and the work is complicated.
Therefore, it is difficult to collectively change the threshold value in a plurality of spinning units, or to appropriately set the threshold value in consideration of the individual differences of the units, etc., to improve the quality of the product.
In addition, in the configuration of the above-mentioned patent document, it is impossible to perform unified management of the entire device including the change history and state grasping of the detected value of the pressure sensor.
In addition, each pressure sensor (each spinning unit) needs a configuration for setting the above-mentioned threshold value and detecting the state of fiber accumulation, so the number of components in the entire device is large and the cost is high.

The present invention provides a spinning apparatus that collectively manages pressures in a plurality of air spinning units. A spinning machine includes a plurality of spinning units, and a unit controller and a frame control device which serve as a pressure collective management device. Each of the air spinning units includes a whirling flow generating chamber and a pressure sensor. The whirlingflow generating chamber internally generates a whirling air flow to twist fibers. The pressure sensor detects pressure inside the whirling flow generating chamber. The unit controller includes a receiving section and a pressure abnormality determining section. The receiving section can receive a pressure value signal from each of the pressure sensors. The pressure abnormality determining sectioncompares the pressure value with a predetermined threshold value to determine whether or not the pressure in each of the air spinning units is abnormal.
Description
technical field [0001] The present invention relates to a spinning device including a plurality of air spinning units. Background technique [0002] Japanese Patent Application Laid-Open No. 2006-132035 discloses a configuration in which, in a spinning device (spinning machine) that twists fibers by a whirling airflow generated by an air spinning nozzle, a pressure sensor detects and uses The pressure of the space for exhaust that communicates with the hollow chamber of spinning. In the spinning device of the above-mentioned patent document, when the detected value of the pressure exceeds the threshold value preset in the pressure sensor, it is judged to be in the state of fiber accumulation and the spinning operation is stopped. With this configuration, it is possible to easily detect a state that is likely to cause defects in the spun yarn. [0003] The spinning device of the above patent document includes a plurality of air spinning units, and each air spinning unit inc...
