Embodiment Construction

[0052] figure 1 A winding machine 1 according to the invention is shown. A plurality of winding stations 2 are arranged between the end frames 5 , 6 . In the winding station 2, the spinning package 9 in the unwinding position 10 is rewound into a large package cross-winding package. The winder 1 shown comprises a transport system 3 for spinning bobbins 9 and spinning bobbin tubes 4 .

[0053] The spinning bobbin 9 and the spinning bobbin tube 4 are vertically arranged on the conveying disc 8 . The delivery tray 8 with the full package of spinning packages 9 is transported from the rear side of the winder 1 to the winding station 2 for unwinding. The spinning package 9 is then already in the erect position required for unwinding. On the front of the winding machine 1, a bobbin tube return section 7 is arranged. The empty spinning bobbins 4 discharged from the winding station 2 after unwinding are always conveyed vertically to the end frame 5 via the bobbin return section 7...

Abstract

The invention relates to a winding machine with a conveying system for spinning bobbins and spinning bobbins and a device for recognizing spinning yarn being discharged along the conveying path of the spinning bobbins and to a device for detecting remaining yarn. Device for residual yarn on a bobbin, and relates to a device for identifying residual yarn on a spinning bobbin, having a light source designed for illuminating the spinning bobbin with infrared light, for creating a spinning bobbin An image acquisition unit for the digital image and an analysis unit for analyzing the digital image to determine the remaining yarn. Provision is made to improve the detection of infrared-absorbing residual yarns on spinning bobbins in which the light source is spaced laterally from the spinning bobbin and the analysis unit is designed to detect Contrast difference between lines.

Description

technical field [0001] The invention relates to a device for identifying remaining yarn on a spinning bobbin, with a light source designed to illuminate the spinning bobbin with infrared light, an image acquisition unit for creating a digital image of the spinning bobbin and for analyzing the digital image to determine the analytical unit of the remaining yarn. The invention also relates to a winding machine with a conveying system for spinning bobbins and spinning bobbins and a device for detecting residual yarn on the spinning bobbins. Background technique [0002] Spinning packages with relatively small amounts of yarn are produced on ring spinning machines. The spinning bobbin is rewound on the winder into a large package cross-wound bobbin. The winder can have a delivery system for the spinning bobbins and spinning bobbins. The conveyor system automatically feeds the spinning packages to the individual winding stations of the winder. The conveying of the spinning bo...
