Embodiment Construction

[0025] figure 1 Shown is a schematic sectional view of a station 2 of a textile machine 1 . Station 2 is equipped with spinning equipment 3 for producing yarn 4 in a conventional manner. The yarn drawing device is composed of two yarn drawing rollers 5, and the yarn 4 is extracted from the spinning device 3 through the yarn drawing device, and sent to the winding device 6, and the yarn is wound on the bobbin 7 through the yarn conveyor 11. For this purpose, the winding device 6 comprises a drive device 8, which, in the above-mentioned normal driving situation, pushes the bobbin in normal rotation in the normal direction of rotation DR (see arrow). Like the direction of rotation DR, the normal withdrawal direction AR of the yarn 4 is also marked with an arrow. The yarn 4 can also be connected to other devices between the draw-off roller 5 and the winding device 6, for example a waxing device 13 (Paraffiniereinrichtung) can be installed.

Abstract

The invention discloses a method for automatically applying a thread (4) to a works station (2) of a textile machine (1). In the method, a nozzle (10) sucks an end (4a) of the thread (4) on a surfaceof a bobbin (7); the thread (4) is released and sucked into the nozzle (10) from the bobbin (7) in the opposite direction to the normal drawing direction (AR); the bobbin (7) is reversely (RR) rotatedby a driving device (8); a thread loop (4b) formed by tensioning the thread (4) through the delivery action of a thread feeding member (9) is transmitted to a connection member (12); the bobbin (7) is also driven in the reverse direction (RR) during the tensioning of the thread loop (4b); and the thread (4) is loosened from the bobbin (7) and the reversal speed of the bobbin (7) is adjusted according to the delivery action of the thread feeding member (9). The invention also discloses a textile machine (1) with at least one station (2) comprising: a nozzle (10) for finding an end (4a) of a thread (4) from the surface of a bobbin (7) and sucks the thread (4); a driving device (8) that drives the bobbin (7) such that the thread (4) is released from the bobbin (7) in a direction opposite tothe normal drawing direction (AR); a connection member (12) which automatically completes connection of the thread (4); a thread feeding member (9) which tensions the thread (4) to form a thread loop(4b) and transmits the thread loop (4b) to the connection member (12); and a controller (15), wherein the driving device (8) drives the bobbin (7) accordingly.

Description

technical field [0001] The invention relates to an automatic wiring method (or yarn processing method) used in a textile machine station, wherein, the suction nozzle sucks the end of the yarn on the surface of the bobbin, and the yarn is drawn in the direction opposite to the normal drawing direction. Released from the bobbin and sucked into the suction nozzle; the bobbin is reversely driven by the driving device; the yarn loop formed by the yarn is tightened by the feeding action of the yarn feeding part and delivered to the splicing part. In addition, the present invention also relates to a textile machine, which has at least one station, and the textile machine comprises: a suction nozzle, which is used to search for the end of the yarn on the surface of the bobbin and suck the yarn; a drive device, which uses It is used to drive the bobbin so that the yarn is released from the bobbin in the direction opposite to the normal drawing direction. In addition, the textile machi...
