Embodiment Construction

[0032]The detection operation is carried out as follows. The stop device 2 is activated and stops the arriving plate 10 conveyed by the conveyor belt 1 on which the bobbins to be inspected are located. The plate 10 is stopped in a position in which the bobbin 6 is detected, which is located between the optical sensor 4 and the lighting panel 5 which can be powered on continuously or only in the presence of the plate . The lighting panel can be made with a light-emitting opaque surface or, according to a preferred embodiment of the invention, a panel comprising a series of light-emitting points such as light-emitting diodes distributed over the surface of the panel (led). The LED panel is charged with a low DC voltage, it doesn't require much maintenance and can be plugged in only for photography moments.

[0033] The size of the illuminated panel preferably exceeds the size of the main bobbin 6 to be identified and differentiated, so that it stands out particularly against ...

Abstract

Device and process for recognizing and distinguishing the spools carried by plates at the outlet of a bobbin-winding station on the basis of their yarn content, its image being taken by a photocamera used with the diascopic technique, the photocamera bidimensionally processing the image taken to distinguish the spools and giving a signal to suitably direct the plate on the basis of the observation effected.

Description

technical field [0001] The present invention relates to a device and method for moving and controlling a bobbin circulating in an automatic winder. In the yarn production technique widely used in industrial practice, a first spinning step - usually ring spinning, which produces yarn on bobbins - is followed by a second winding step, in Said second winding step unwinds the yarn from its bobbin, corrects its defects and rewinds it onto the bobbin. The winding operation is carried out in a bobbin winder located downstream of the spinning machine. Background technique [0002] In the recently conceived bobbins, the technique of moving bobbins and bobbins is widely prevalent, while using plate supports to be placed on conveyor belts or similar mobile service mechanisms of the machine to transport said bobbins or bobbins individually to the winder. The yarn unit and delivery from the winding unit support said bobbins and bobbins in an upright position on their plates during thei...
