Problems solved by technology

Drawbacks of this arrangement are the relatively low reliability of the detection process for more robust packages, such as those produced on ring spinning machines, and the risk of damage to the package through contact with the excitation surface
Another disadvantage is the relatively large amount of suction air required to suck the excited yarn end from the surface of the bobbin to the suction nozzle

Embodiment Construction

[0026] A method for detecting a yarn end on a bobbin in a textile machine and a device for performing the method will be described with reference to an example of embodiment in a spinning machine for producing yarn 1, said yarn being It is wound onto a rotating bobbin 2 which is rotatably mounted in the machine structure of the textile machine. The wound yarn 1 forms a package 3 with a surface 4 on a bobbin 2 . The method and device can also be used in a textile machine for processing yarn 1 .

[0027] exist figure 1 and figure 2 In the example of embodiment, the movable mechanism 6 is manufactured as an endless movable belt wound around at least two guide pulleys 16, at least one of which is connected to a rotary drive. In a not shown example of embodiment, the system of pulleys 16 is provided with tensioning means to ensure that the required tension is maintained in the movable mechanism 6 .

Abstract

The invention relates to a method and a device for detecting the end of a yarn on a bobbin (2) in a textile machine for producing or processing yarn, especially after the winding has been interrupted due to a break of the yarn (1), when after the break , the bobbin (2) is approached by a suction nozzle (11) into which the yarn (1) end is sucked from the rotating bobbin. A rod (8) and a movable mechanism (6) with a carrying surface (5) approach the surface (4) of the package (3) on said bobbin (2). The movable mechanism (6) is moving in a different direction than the rotating bobbin (2), wherein the end of the yarn (1) is captured by the movement of the movable mechanism (6) and released from the bobbin (2) is retrieved and the yarn (1) end is carried to the suction nozzle (11).

Description

technical field [0001] The present invention relates to a method and a device for detecting the end of a yarn on a bobbin in a textile machine for producing or processing yarn, especially after the winding has been interrupted due to a yarn break, when the bobbin is formed by A suction nozzle is approached into which the yarn end is sucked from the rotating bobbin. Background technique [0002] In yarn manufacture or processing, yarn is wound onto bobbins for further processing. Due to different circumferences, irregularities, etc., yarn breakages occur during winding of the yarn onto bobbins. After a yarn break, the yarn end is wound onto the bobbin, and for further manipulations on the machine, such as restoring the winding of the yarn, it is necessary to detect the yarn end on the bobbin, to catch the yarn end and introduce it into a suitable working mechanism of the textile machine, which performs further operations to restore the yarn winding. In principle, this coul...
