METHOD FOR MONITORING YARN AT A WORKSTATION OF A TEXTILE MACHINE AND A TEXTILE MACHINE FOR PERFORMING THE METHOD

摘要

The invention relates to a method for monitoring yarn (3) at a workstation of a textile machine having a row of workstations arranged next to each other, in which the yarn (3) being produced is during its production monitored by a yarn quality sensor (9), yarn defects are detected (3), the quality of yarn is evaluated (3) and the data is transmitted to a control device (8), which makes decisions about the subsequent processes at the workstation. The control device (8) transmits to the yarn quality sensor (9) online and real-time information about the current operating conditions of the workstation and the yarn quality sensor (9) accordingly adjusts the processes of monitoring the yarn (3) and evaluating the yarn parameters (3), whereupon the results of the thus adjusted process of monitoring the quality of the yarn (3) are sent to the control device (8) so that decisions can be made about further processes at the workstation. The invention also relates to a textile machine with a device for monitoring yarn (3) at the workstation, which comprises a row of workstations arranged next to each other, where each workstation comprises a yarn quality sensor (9), which is aligned with the working path of yarn (3) and which is connected to a control device (8) provided with means for making decisions about the yarn (3) parameters being detected and about the steps to follow at the workstation after detecting undesirable yarn (3) parameters. The yarn quality sensor (9) and the control device (8) are interconnected by a means (11) for online and real-time bidirectional transmission of the information about the parameters of the yarn (3) being produced and/or about changing conditions at the workstation.
