Definitions
- the latter is arranged on a frame 23 (fig. 1), and is associated with a conventional automatic replacement mechanism, not shown in the figure.
- the reel 15 is made to rotate, in a conventional manner, by means of a roller 24 associated with an electric motor 25 which, for the functions that will be described hereafter, is commanded by a command unit 26.
- the accumulation cylinder 11 is driven by an electric motor 16 which, in this case, is arranged coaxial inside the cylinder 11 itself and is mounted on a support 27.
- the motor 16 of the motorized cylinder 11 is governed by the measurement made by the detector 13, and its speed of rotation is controlled so as to keep this value substantially constant.
- Two guide eyelets 28 are arranged one between said sensor 22 and the unwinding element 12, and the other between the tension detector 13 and the positioning device 14; their function is to guide the thread 30.
- the functioning of the device 10 provides a normal working step, a step to accumulate the reserve and a transition step.
- the accumulation step entails a rotation of the unwinder 12, together with the accumulation cylinder 11, since the unwinder 12 is no longer held, or rather drawn in the opposite direction to the rotation of the cylinder 11 by the thread 30 which exits in order to wind onto the reel 15.
- the number of revolutions that the cylinder 11, together with the unwinder 12, performs during the formation of the reserve can therefore be detected by the encoder 17 and memorized in the command unit 26, substantially quantifying the quantity of thread accumulated during the lifting operation.
- the step of accumulating the thread 30 on the cylinder 11 is stopped as soon as a new cop has been located in the frame 23 and the collection operation can be restarted.
- the command unit 26 restores control of the angular position of the unwinder 12, so as to progressively return the speed of rotation of the reel 15 in synchrony with that of the accumulation cylinder 11. Moreover, the support 19 of the positioning device 14 is commanded to rise, displacing the reserve of thread 30 progressively towards the top of the cylinder 11, that is, to the normal working position.
- the cylinder 11 can be of the replaceable type, for example by others of a different height or diameter, according to the times required for the lifting operations and hence in relation to the quantity of thread that has to be temporarily accumulated.
- the step-by-step motor of the positioning device 14 can be replaced by a linear motor with controlled drive, or by any type of motor, possibly with feedback control.
- other sensors or detectors may be provided, to control the tension and/or the presence of the thread at other points in the path of said thread.
