Problems solved by technology

This spool must then be recovered by the machine after the spinning frame, the spooler who must unwind the spool recovers the yarn consisting of single strands and eliminates it, which wastes material and time
There is no sensor known in the art that detects the presence of these two yarns in an efficient manner

Embodiment Construction

[0059] Figure 2A A schematic sectional view of elements of a spinning frame including the control device 2000 is shown. Figure 2B show Figure 2A Schematic front view of the spinning frame and elements of the control device 2000.

[0060] The spinning frame may basically correspond to the spinning frame 1000 , the sensor 1300 is omitted, and the function of the sensor 1300 is replaced and improved by the control device 2000 . More generally, however, the control device 2000 can be installed on several types of spinning frames even different from those described here.

[0061] The control device 2000 may be positioned near the last pair of drafting rollers 1105-1106, possibly below the suction tube 1400 when provided, or in some cases above the suction tube 1400. In some embodiments, the control device 2000 may be mounted at a distance of about 10 mm below the suction tube 1400 and / or at a distance of about 30 mm below the last pair of rollers 1105-1106. More generally, i...

Abstract

The invention is a control device (5000, 7000) for a spinning frame (1000) comprising a drafting device configured to draft a roving (1201) and thereby obtain a first yarn (1211, 1216, 1218) Stretching rollers (1101‑1106); the control device includes an optical movement sensor (5801), a frequency meter (5802), wherein the optical movement sensor (5801) is configured to measure the movement of the yarn (1211, 1216, 1218), wherein the frequency The meter (5802) is configured to receive the signal measured by the optical movement sensor (5801) and measure at least one oscillation frequency (Fmax_int) of the yarn (1211, 1216, 1218).

Description

technical field [0001] The invention relates to a control device for a spinning frame. Background technique [0002] Figure 1A A schematic cross-sectional view of elements of a spinning frame 1000 known in the art is shown. Figure 1B A schematic front view of elements of the spinning frame 1000 is shown. [0003] The spinning frame 1000 basically comprises a main body 1107 on which a plurality of spindles are positioned. The number of spindles can be very large, in fact spinning frames equipped with more than 1800 spindles are known. Each spindle includes a plurality of drafting rollers 1101 - 1106 , typically three pairs 1101 and 1102 , 1103 and 1104 , 1105 and 1106 , which draft rovings 1201 arriving from bobbins 1202 . The drafting process is performed by rotating three pairs of drafting rollers 1101-1106 at different speeds. In particular, it is sufficient that at least one first pair, such as rollers 1101-1102, rotates at a lower speed than a second pair, such as ...
