Embodiment Construction

[0015] figure 1 The air spinning machine 1 shown has a plurality of work stations 4 between the end positions 2 and 3, which are arranged on both longitudinal sides of the spinning machine. The workstations 4 , which in each case include the weaving and winding mechanisms, are maintained by four maintenance units 5 , 5A, 5B, 5C. The maintenance units 5 , 5A, 5B, 5C are movable along the machine side on the guide rail structure 6 . One of the maintenance units 5, 5A, 5B, 5C works automatically if a yarn break occurs at one of the workstations 4 or a bobbin needs to be replaced. The air spinning machine 1 further comprises a cross-winding bobbin conveying device 7 and a bobbin feeding device 8 arranged between the workstations 4, the cross-winding bobbin conveying device 7 is used for conveying the completed cross-winding bobbins. The bobbin supply device 8 (in this example) comprises a central bobbin magazine 9 arranged at the end of the machine, a bobbin distribution device ...

Abstract

The invention relates to a rotor spinning machine comprising a plurality of working stations and a bobbin supplying device extending along the machine. At least two service units supplying the working stations with bobbins are supplied with bobbins by the supply device. A control device (14) for controlling the service units (5, SA, SB, SC) is embodied in such a way that it prevents a subsequent request for bobbins from the second service unit (5A) during a request for bobbins from the first service unit (5) positioned downstream in relation to the transport direction of the supply device, until the previous bobbin request has been fulfilled. In this way, unnecessary downtime of the working stations and unnecessary waiting time for the service units (5, 5A, 5B, SC) is avoided.

Description

technical field [0001] The invention relates to an air spinning machine according to the preamble of claim 1 . Background technique [0002] A maintenance unit is used on the air spinning machine and is movable on guide rails on the longitudinal sides of the air spinning machine. The function of the maintenance device is to start spinning after a yarn break and to supply the bobbins to the spinning station of the rotor spinning machine. In order to keep the downtime of the spinning station as short as possible in the event of a yarn break or bobbin change, several maintenance units are used on the rotor spinning machine, for example two on each longitudinal side of the spinning machine. [0003] DE 199 05 856 A1 describes an air spinning machine with a plurality of workstations between its end frames, which are arranged on both longitudinal sides of the spinning machine. Each of these workstations has a spinning mechanism and a downstream winding mechanism, and is supplied...
