Problems solved by technology
[0009] It will therefore be appreciated that in production lines for leather skins and / or the like, how continuous detection has hitherto been particularly difficult and generally unreliable, since quite frequently the detected color change is not actually present in the sample , but due to variations in the texture of the sample hide itself, and / or due to the presence of wrinkles or surface defects, variations in the actual detected color are derived from unrealistic detection

Embodiment Construction
[0027] As shown in the figure, the device 2 for detecting the color of leather skin and / or the like according to the present invention, including a light sensor 4, is arranged to capture the light radiation reflected from the leather skin 6, which is placed on The color of the leather skin is to be detected on the support surface 7, which is composed of a workbench or a conveyor belt 8 of a machine 10 or equipment 12, which is used to process and / or manage the leather skin.
[0028] It should be understood that "leather hide and / or the like" herein means a two-dimensional object made of natural and / or synthetic leather hides or made of other synthetic materials, such as plastics, It has characteristics similar to or at least in common with leather, and generally speaking, refers to a two-dimensional object used in the leather goods industry. Preferably, an article made of leather and / or the like whose color is to be tested is related to a finished or substantially finished articl...

A device (2) for detecting the color of leather hides and / or the like, which is installable on machines (10) and / or in plants (12) for processing and / or managing leather hides and the like, characterized in that it comprises: a surface (7) for supporting at least one leather hide (6) of which the color is to be detected, a light source (18) prepared to emit a light radiation of known spectral composition onto the leather hide (6) supported on said surface (7), an optical sensor (4) prepared to capture the light radiation which is emitted from said light source (18) and is reflected from said leather hide (6), means (16) positioned at said optical sensor (4), for keeping the distance constant between said optical sensor (4) and said leather hide (6) supported on said surface (7), optical filtration means (20) associated with said optical sensor (4) to extract the values of the chromatic components of said light radiation captured by said optical sensor (4), a processing unit (28) whichreceives the values of said chromatic components and is configured to compare them with preset reference values and / or to calculate and identify the corresponding color.
Description
Technical field [0001] The present invention relates to a device for detecting the color of leather skin or the like, which is installed on a machine and / or equipment for processing and / or managing leather skin or the like. Background technique [0002] In the case of processing leather, the final color of the leather itself is a particularly important parameter for judging the quality and repeatability of the dyeing process. In particular, the effect of repeatability is to give the basic color of the leather skin, and it is done by spraying an atomized liquid, usually a dye, or by applying a pigment or fixing agent. In particular, the color is required to be uniformly applied to the entire surface of the leather skin. [0003] In such occasions, it is also required that the leather skins to be processed belong to the same batch or two different batches have the same initial color scale. [0004] In the current situation, to detect the color of leather, a colorimeter is used, which...
