Abstract
Described is a control and programming system and method for producing a ball of thread having a plurality of stretches with different colors along the longitudinal direction with a ball winding machine comprising: a device for acquiring the chromatic characteristics of the thread connected to a respective control unit, a device for moving the thread towards the ball winding machine and a device for cutting the thread.
Claims20
A control and programming system for producing a ball of thread for a ball winding machine, the thread having a plurality of stretches with different colours along the relative longitudinal direction, characterised in that it comprises:
- a device for continuously acquiring the chromatic characteristics of the thread connected to a respective control unit,
- a device for moving the thread towards the ball winding machine and
- a device located downstream at least of the acquisition device.
A method for controlling and programming the production of a ball of thread having stretches of different colours along the longitudinal direction comprising the following operating steps:
- programming a system in such a way as to learn, by means of an acquisition device, the type of stretch of colour selected as initial colour of the ball, and the interval of operation after which to activate a cutting device,
- preparing the thread in a winding head of a ball winding machine located downstream of the system in such a way that the colour is the first to be wound on the ball,
- activating the winding head,
- activating the cutting device after the predetermined operating interval and when the selected point of the next stretch of colour is located at the cutting device.
