<p>A device and a process for the regulation of the drive means which drive the various operating steps of the individual collection station of a winding machine, e.g., an automatic coner machine, wherein each collection station is equipped with a drive source. More particularly, said device comprises: - a three-phase motor driving the drive roll by means of a positive transmission, such as a toothed belt; - a variable-frequency inverter, which feeds and pilots the drive source, in conformity with the signals coming from a central control unit, which in its turn processes the working parameters coming from the winding station, together with the monitored data coming, in feedback, from the speed monitoring probe-wheel; - a speed monitoring probe-wheel keyed on the drive shaft, capable of measuring the speed and the length of the thread being collected, according to preestablished sequences and operating cycles; - a fully-reversible power circuit capable of making electric power flow both from the power supply distribution system to the drive source, and from this latter to the other drive sources of the operating front; or towards the same power supply distribution system.</p> |
