Spinning Point of a Spinning Machine and Method for the Operation of the Same

摘要

The invention relates to a spinning point (1) of a spinning machine, whereas the spinning point (1) includes a spinning unit (5), a drawing-off device (6) for the yarn (2) downstream of the spinning unit (5) in the direction of transport (T) and a yarn accumulator (7) downstream of the drawing-off device (6) for the intermediate accumulation of a section of yarn, whereas the yarn accumulator (7) is allocated a sensor system (8) for monitoring the filling level of the yarn accumulator (7), whereas the spinning point includes a spooling device (9) for the yarn (2) downstream of the yarn accumulator (7), along with a return unit (10), with the assistance of which an end of the yarn (11), which is found within the yarn accumulator (7) after a yarn break, is able to be returned in the area of the spinning point (1). What is also proposed is a method for the operation of a spinning point (1), characterized in that its spooling device (9) is stopped in such a manner that, after the stop of the spooling device (9), an end section of the yarn (2) remains within the yarn accumulator (7), that, subsequent to this, a part of the yarn (2) is separated with the assistance of a yarn separation unit (17) internal to the spinning point, and that the end of the yarn (11) that newly arises in this manner is returned with the assistance of a return unit (10) internal to the spinning point in the area of the spinning point (1), and that a spinning process is then carried out.

主权项

1. Spinning point of a spinning machine, which serves the purpose of producing a yarn (2) from a fiber composite (4) supplied to the spinning point (1) in a direction of transport (T), whereas the spinning point (1) includes at least the following:
a spinning unit (5) with tools for the production of the yarn (2), a drawing-off device (6) downstream of the spinning unit (5) in the direction of transport (T) for the drawing off of the yarn (2) from the spinning unit (5), a yarn accumulator (7) downstream of the drawing-off device (6) for the intermediate accumulation of a section of yarn, whereas the yarn accumulator (7) is allocated a sensor system (8) for monitoring the filling level of the yarn accumulator (7), a spooling device (9) downstream of the yarn accumulator (7) for rewinding the yarn (2), along with a return unit (10), with the assistance of which an end of the yarn (11), which is found within the yarn accumulator (7) after a yarn break, is able to be returned in the area of the spinning point (1).
