The invention relates to a method of controlling a sensor (3) of physical quantities and/or an optical signalling means (7) on a textile machine, especially a yarn manufacturing machine, in which the sensor (3) of physical quantities is primarily intended to detect the state at a workstation and the optical signalling means (7) is primarily intended to provide visual information about the state of a workstation, group of workstations or machine. The sensor (3) of physical quantities and/or the optical signalling means (7) is deliberately switched to the secondary operating mode other than the primary purpose of the sensor (3) and/or the signalling means (7), working operations are performed in this secondary operating mode and subsequently the sensor (3) of physical quantities and/or the optical signalling means (7) targetedly switches back to the primary operating mode.

In addition, the invention relates to a textile machine, especially a yarn manufacturing machine, having at least one row of workstations comprising at least one sensor (3) of physical quantities and/or one optical signalling means (7), whereby the sensor (3) of physical quantities is primarily intended to detect the state at a workstation and the optical signalling means (7) is primarily intended to provide visual information about the state of a workstation, group of workstations or machine and the sensor (3) of physical quantities and/or the optical signalling means (7) are connected to a control and evaluation device (6). The control and evaluation device (6) comprises means for targetedly switching the sensor (3) of physical quantities and/or the optical signalling means (7) to the secondary operating mode in which the sensor (3) of physical quantities and/or the optical signalling means (7) is used in the same place for at least one purpose other than its primary purpose.

A detection device is disclosed for detecting an abnormal object in a printing path. The detection device includes a first frame body, a first rotation shaft, two flexible portions and a detection module. The first rotation shaft is pivotally connected to the first frame body and has a first central axis. The two flexible portions are disposed at two opposite ends of the first rotation shaft along the first central axis, to provide an initial torque. Each flexible portion is connected between the first rotation shaft and the first frame body. The detection module includes a detection plate connected to the first rotation shaft. When the detection plate is forced by the abnormal object, the detection plate drives the first rotation shaft against the initial torque to rotate around the first central axis, so that the detection module detects the rotation of the first rotation shaft and the detection plate.

A textile machine for producing cross-wound packages, which has a plurality of workstations on the two longitudinal sides of the machine and is equipped with a tube magazine arranged at an end of the machine, the tube magazine having a plurality of empty-tube transport rows, driven by electric motor and loaded with empty tubes of different yarn lots. In order to avoid the fixed division of the empty-tube transport rows that hitherto was defined by the construction of the tube magazine and thus to avoid limited variations in the yarn lot management, the invention provides for the empty-tube transport rows to be equipped with electric drives, which are connected to a control unit of the textile machine, the machine control system being designed in such a way that different lot management programs are set by software.

The apparatus and methods disclosed herein are directed to detecting the presence of a whipping tail when using a fiber winding system to wind a fiber onto a rotating spool. The fiber is guided onto the rotating spool through a containment region between the spool and a whip shield to create the wound fiber. The whipping tail outwardly extends from the wound fiber and periodically or quasi-periodically passes through a light beam to create a series intensity dips in the light beam, thereby forming a modulated light beam. The modulated light beam is converted into a digital electrical signal made up of electrical pulses having a timing defined by the intensity dips. The measured timing of the electrical pulses is compared to an estimated timing based on the rotating spool to ascertain the presence of a whipping tail.

The present disclosure refers to a method and a system for tracking cable drums and length of cable on the drum. A method includes attaching a tracker device with a tracker identifier to a cable drum with a drum identifier, said drum identifier being associated in a database with drum dimensions and with cable dimensions of a cable stored on the drum. The method includes associating in the database the drum identifier also with the tracker identifier. The method includes when an event comprising at least a shock and/or a number of rotations of the cable drum around a longitudinal axis occurs, activating a first electronic circuit of the tracker device including a sensing device that detects at least the event, storing the detected event in a local memory of the tracker device and switching the first electronic circuit to standby mode after the detected event is stored.
