Embodiment Construction

[0039] FIG. 1 schematically shows a device for carrying out the method according to the invention. The device mainly comprises a CCD camera 1 connected to an image processing device 4 via a signal line 6 .

[0040] The memory 3 is also connected to the image processing device 4 , for example via a signal line 7 , and the display device 5 is also connected to the image processing device 4 via a signal line 8 .

[0041] In addition, a light source 16 is preferably provided in order to properly illuminate the bobbin 2 to be identified, which light source 16 is preferably a constant diffuse light source. As shown in FIG. 1 , the CCD camera 1 is preferably arranged at an angle α with respect to the bobbin axis 17 of the bobbin 2 to be detected, so that in the area of ​​the bobbin 2 the viewing field (blickfeld) that can be detected by the camera 1 includes the bobbin at least half the length.

[0042] However, the image processing means 4 and the associated memory 3 and display m...

Abstract

The present invention relates to a method and a device for the automated identification of bobbin tubes, wherein the bobbin tube is used at a workstation for producing textile machine for cross winding bobbin, and the method and the device is capable of automatically identifying the bobbin tube using the special characteristic of the bobbin tube during a multi-batch operation process of the textile machine. According to the invention, the method involves comparing actually recorded image information of the bobbin tube with image information of an already classified bobbin tube. The bobbin tube (2) is identified when a fixable match of the bobbin tube (2) with the already classified bobbin tube is obtained using a pattern matching process or a color matching process.

Description

technical field [0001] The invention relates to a method and a device for the automatic identification of bobbins used at a workstation of a textile machine producing cross-wound bobbins, in particular in the multi-batch operation of such a textile machine (Mehrpartienbetrieb ) process using the specific characteristics of the bobbin to automatically identify the bobbin. Background technique [0002] It has long been known in the textile machine industry to mark bobbins in different colors so that operators can identify different yarn batches. It is known to identify roving bobbins by means of colored reusable bobbins, and it is also known to wind worsted bobbins on colored and likewise reusable bobbins. Such reusable tubes are usually made of a stable plastic material and are dyed in a single colour. [0003] For example, DE 19749,024 A1 describes a roving bobbin transport system which connects a roving frame, a so-called flyer roving frame, to a ring spinning frame arran...
