The invention relates to a method of and a service device of a textile machine, especially of the spinning machine, searching the yarn end on bobbin (1) of a textile machine, especially of the spinning machine with individual drive of the live roller (3) of a bobbin (1) being wound, wherein the method is characterized in that during the course of renewal of the winding process, on the working station of the textile machine, the searching nozzle (4) on a service device approaches the bobbin (1) and due to the action of vacuum, the yarn end is sucked from the rotating bobbin (1) into the searching nozzle (4). The method and device consist in that the vertical position of longitudinal axis of the bobbin (1) is detected by means of a leveling element (20) and a sensor (42) at the first movement of the searching nozzle (4) after detection of which the first movement is stopped, through which the mouth (41) of the searching nozzle (4) is set in the original position for shifting towards the bobbin (1), after which as a result of the in advance determined distance of the mouth (41) of the searching nozzle (4) in the searching position from surface of the bobbin (1) from the vertical position of longitudinal axis of the bobbin (1) still laying on the live roller (3), the searching position of the mouth (41) of the searching nozzle (4) is determined and which advances into this position by a second movement of the searching nozzle (4); in a different direction when compared with the first movement, through which the mouth (41) of the searching nozzle (4) approaches the perimeter of the bobbin (1) to the in advance determined distance at whatever diameter of the bobbin (1) without necessity to measure continuously the diameter of the bobbin (1). The invention also relates to a textile machine service device, particularly that of the spinning machine. |
