Embodiment Construction

[0026] figure 1 The combination of a ring spinning machine and an automatic cross-winding winder is shown in schematic top view. Here, the ring spinning machine is marked 1, while the automatic cross-winding machine is marked 2. As is known per se and is therefore only indicated schematically with arrows, the two textile machines are connected via a bobbin / empty tube conveyor system 30 . The conveying sections of the bobbin / empty bobbin conveying system 30, arranged in the area of ​​the automatic cross-winding winder, are the bobbin conveying section 3, the bobbin return section 4, the reversibly driven storage section 5 and the delivery to the winding station The lateral conveying section 6. Furthermore, at least one so-called pretreatment section 7 is connected to the bobbin delivery section 3 , the ends of which are connected via branches 8 and 9 to the storage section 5 or again to the bobbin delivery section 3 .

[0027] In the region of the pretreatment section 7, a p...

Abstract

The invention relates to a method of preprocessing bobbin made in a spinning machine to be rewound in an automatic cross-wound machine. Herein, the yarn preprocessing device comprises a yarn start station for starting a yarn and a yarn taking station for taking and setting the yarn at a preprocessing position. Activating mechanism for activating the bobbin to rotate around the longitudinal axle is provided at the yarn starting station and the yarn taking station respectively. The yarn taking station has a sensor for detecting taking the yarn successfully. According to the invention the numberof revolution of each bobbin (16) is counted and reported to the controller (15) before the sensor (17) detects the yarn is taken successfully in the yarn taking station (12). An average value (MW) of bobbins (16) average revolutions in the yarn taking station (12) is calculated in the controller (15), and the top number of revolution is adjusted referring to MV. The subsequent bobbin (16)in the yarn taking station (12) will rotate with the top number of revolution when the yarn is not taken in successfully.

Description

technical field [0001] The invention relates to a method for the pretreatment of bobbins produced on a spinning machine for subsequent rewinding on an automatic cross-winding winder, and a device for carrying out the method. Background technique [0002] Bobbins, especially those produced on ring spinning machines, often have so-called back wrapping yarns determined by the way this textile machine works. This means that such a bobbin is placed in such a way that it is not possible to receive the end of the thread at the winding station of the automatic cross-winding winder and, accordingly, it is not possible to transfer the end of the thread to the winding station without special measures being taken beforehand yarn supply mechanism. [0003] For this reason, the bobbin is usually passed through a so-called pretreatment device on its way from the ring spinning machine to the winding station of the automatic cross-winding winder, in which the bobbin yarn is It is drawn out...
