Abstract

Filatoio, in particolare filatoio ad anelli con almeno un gruppo di punti filatura, nei quali rispettivamente durante intervalli di tempo principali tubetti vuoti vengono bobinati con filato e durante intervalli di tempo intermedi, i quali si trovano fra gli intervalli di tempo principali, i tubetti piani bobinati vengono sostituiti da un dispositivo per il cambio di tubetti con barra di levata, con tubetti vuoti. Esso è dotato di almeno un dispositivo di trasporto di tubetti, per mezzo del quale tubetti vuoti o rispettivamente pieni vengono alimentati verso i punti di filatura o rispettivamente asportati da essi. Il filatoio è corredato di almeno un motore principale, il quale serve all'azionamento dei fusi, applicati ai punti di filatura, durante gli intervalli di tempo principali, il quale/i quali motore/i principale/i viene/vengono alimentato/i da convertitori di frequenza principali con corrente di alimentazione di frequenza regolabile, e con almeno un motore supplementare per l'azionamento del dispositivo per il cambio di tubetti durante gli intervalli di tempo intermedi. In questo caso almeno uno dei due convertitori di frequenza principali è commutabile negli intervalli di tempo intermedi su almeno un motore supplementare per la alimentazione del o dei motore/i concernente/i con corrente di alimentazione di frequenza regolabile. Il motore supplementare per il dispositivo per il cambio di tubetti è azionabile anche durante gli intervalli di tempo principali.Spinning machine, in particular ring spinning machine with at least a group of spinning points, where respectively during main time intervals empty tubes are spooled with yarn and during intermediate time intervals, which are located between the main time intervals, the flat tubes reels are replaced by a device for changing tubes with a lifting bar, with empty tubes. It is equipped with at least one tube transport device, by means of which empty or respectively filled tubes are fed to or respectively removed from the spinning points. The spinning machine is equipped with at least one main motor, which is used to drive the spindles, applied to the spinning points, during the main time intervals, which the main motor (s) is / are powered by main frequency converters with adjustable frequency supply current, and with at least one additional motor for operating the device for changing tubes during intermediate time intervals. In this case, at least one of the two main frequency converters is switchable in the intermediate time intervals on at least one additional motor for supplying the motor (s) relating to the adjustable frequency supply current. The additional motor for the tube change device can also be operated during the main time intervals.
