Description
Technical Field
The subject of the invention is a ring spinning machine (ring spinning machine) of a spinning line to obtain bobbins of yarn from bobbins of roving (generally originating from the roving machine).
Background
It is known that, after drafting and twisting (twist) the roving, the spinning machine is able to process the bobbins of roving to obtain bobbins of yarn therefrom.
To this end, the spinning machine comprises a frame (gap) extending along a longitudinal axis, on which bobbins of roving are suspended, a drawing device (drawing device) placed below the frame, comprising a set of cylinders with longitudinal extension, between which the roving passes for drawing, and a creel (bank) carrying a row of spindles along the longitudinal axis, the spindles rotating about the vertical axis of the spindles, the drawn and twisted yarn being wound on the spindles.
In order to increase the productivity of the spinning machine, there are generally two opposite creels, each provided with a row of spindles.
The spindles are rotated about a vertical axis by a belt drive in which the belt is driven by an electric motor and engages the spindles of the two creels.
There are many solutions related to driving devices for spinning machines.
Examples are described in international applications WO-A1-2009/040734 and WO-A1-2009/040839, published EP-A1-0400260, italian patent application No. 10 2018 000 009 103, all in the name of the applicant. Other solutions are described in documents US 5,590,514, US 4,944,144, WO-A1-2007/039260 and DE 2125597.
However, the current trend in this field is to provide creels with a very high number of spindles in order to increase the productivity of the spinning line.
However, the applicant has found that increasing the number of spindles causes drawbacks to occur, both in relation to the operation of the spinning machine and in relation to further aspects, such as the execution of maintenance operations.
For example, it has been found that maintaining optimal synchronization of the RPM of the motor controlling the rotation of the spindle is particularly difficult when the number of spindles is very large (e.g. over 1900) with further technical drawbacks.
