Problems solved by technology

[0006] In known leather quality inspections, it has proven to be disadvantageous that only very experienced workers who have inspected a large number of genuine hides can carry out a visual final inspection
Furthermore, the visual final inspection is very time consuming and even though objective evaluation criteria have been achieved by developing a leather characteristics catalog, a subjective decision remains in the end

Embodiment Construction

[0022] figure 1 A schematic representation of Cow 1 is shown, in which the location of a typical epidermal lesion is drawn. On the neck there are epidermal lesions 2 due to hedge and barbed wire lacerations 2 and epidermal lesions 3 due to mites. Moss in the fur causes skin damage 4, excrement site (Dungstelle) causes skin damage 5, brush damage (Striegelverletzung) causes skin damage 6, horn collision (Hornst??) causes skin damage 7 and drives away spines (Treibstachel) and Gabelstiche causes epidermal damage8.

[0023] This is only an excerpt classified in the so-called leather profile with regard to its shape (area, typical size, depth into the leather) and position.

[0024] can continue to be processed in figure 2 The genuine leather 9 shown in is intended for many different uses (leather sofas, leather coats, leather steering wheels...). Different quality grades of genuine leather are processed according to the purpose of use, the expected requirements and the price...

Abstract

The invention relates to a test device (10) for determining the quality of leather (9) in leather production, wherein the test device (10) is designed for testing a quality category of the leather (9) and for outputting a quality value identifying the leather (9) with respect to the quality category, wherein the test device (10) comprises fluoroscopy equipment (16) for testing the homogeneity of the leather (9), by means of which at least partial areas (22, 23, 24, 27, 29) of the leather (9) can be fluoroscopically examined and that are designed for outputting fluoroscopy data (D) to analysis means (19), and the analysis means (19) are designed for comparing the fluoroscopy data (D) to characteristic data typical for skin damage or inhomogeneity in leather (9) and for categorizing detected skin damage of tested partial areas (22, 23, 24, 27, 29) of the leather, and display means (20), and are designed for displaying the categorized skin damage or the quality value of the leather (9), preferably for each partial area (22, 23, 24, 27, 29) of the leather (9).

Description

technical field [0001] The invention relates to a testing device for determining the quality of leather during the manufacture of leather, wherein the testing device is configured for testing the quality grade (Qualitätskategorie) of the leather and for giving a quality value indicating the quality grade of the leather . Background technique [0002] In leather manufacture, the finished leather (Lederhaut) is produced from animal hides in a sequence of mechanical and chemical treatments. Since leather is used in different applications, the quality of genuine leather must be determined before or after a treatment step during leather manufacture in order to determine for which application the genuine leather or parts of genuine leather are suitable. Also basically the value of the leather is reflected by the quality of the finished leather. [0003] In the quality control of leather, a number of different testing devices can be used for testing different quality standards. ...
