  • Publication number: 20240399647
    Abstract: Control closely based on sets of winding data of a fiber bundle is performed even if at least one set of the winding data is skipped. A controller includes a data conversion unit, a reference data setting unit, a transfer unit, and a selector. The data conversion unit converts sets of first winding data generated based on winding conditions into sets of second winding data in which a processing order number is associated with information of a state of a winder. The reference data setting unit sets some of the second winding data as sets of reference data in advance. The transfer unit transfers a selected set of the second winding data to the winder, each time a unit time elapses. The selector is able to set an override value that is used for determining a skip number.

  • Publication number: 20240400342
    Abstract: It is possible to suppress damage to a yarn path guide mechanism and a textile machine. There is a first supporter which makes contact with a supporting shaft supporting a roller, a second supporter which is capable of making contact with the supporting shaft, and a biasing member which biases the second supporter in a direction in which the supporting shaft is sandwiched between the second supporter and the first supporter. When a virtual straight line which passes through a winding center and a rotation center is a first virtual straight line whereas a virtual straight line which extends in a direction orthogonal to the first virtual straight line and passes through the rotation center is a second virtual straight line, the second supporter makes contact with a part of the supporting shaft, which is positionally opposite to the winding center over the second virtual straight line.
