Description

DESCRIPTION of the invention entitled: “Management system for a leather or similar processing plant” of GER ELETTRONICA Srl in Montecchio Maggiore (Vicenza) 5 filed on September 11, 2024 at the Italian Patent and Trademark Office. * * * * * * * FIELD OF TECHNOLOGY The present invention relates to a management system for a 10 plant for the treatment of leather or similar products. The present invention also relates to a treatment plant for skins, or similar, which includes the aforementioned management system. Therefore, the present invention finds advantageous use in the sector leather or similar treatment technician, particularly in the processing of 15 transform raw hides into finished hides. STATE OF THE ART As is known, the process of treating skins to go from skin from raw to finished leather involves a number of intermediate leather processing steps same, such as splitting, tanning, shaving, pressing, drying, 20 sanding, painting, ironing, etc. These intermediate processes can be carried out in sequence at the same establishment managed by a single entity, or they can be carried out in sequence at geographically distinct locations but always managed by the same subject, or they can be carried out in sequence 25 from different subjects at their respective offices. The leather treatment process lasts several days (on average it can last about 20 days) and also for this reason, currently, it is rather 801.1246 complex to follow the batches of hides during the various processes foreseen in the treatment process. Generally, finished hides are stored or sold according to certain criteria and, in particular, before tanning, semi-finished leathers 5 are assigned to a specific type of product that you want to obtain at end of the process. One drawback of traditional solutions is the lack of traceability of information relating to the processing carried out on the hides. More in details, currently, are not properly documented in a 10 detailed the processes, not even those carried out within the same factory or tannery, nor is it possible to effectively monitor and track the batches of skins. This compromises the quality of the final product, leading to customer dissatisfaction, economic losses and increases in costs production. 15 Another drawback of traditional solutions is the fact that The packaging of the skins does not take into account the accumulated information during the treatment process. Packaging is often conducted based solely on data collected in the final phase, such as the quality grade attributed to the skins, neglecting data collected in previous processing phases or the 20 specific characteristics of the batches. This makes the process inefficient and heavily dependent on manual operations which inevitably rely on incomplete information. PURPOSES OF THE INVENTION The purpose of this invention is to propose a management system 25 for a leather or similar treatment plant, which exceeds - at least in part - the the aforementioned drawbacks present in currently known solutions. Another purpose of the invention is to trace the skins during the subsequent processes involved in the leather treatment process, and this is for 801.1246 processes carried out in the same plant as well as processes carried out in separate establishments, possibly even managed by different entities. Another purpose of the invention is to collect information on the skins during the subsequent processes foreseen in the treatment process, and this is 5 for processes carried out in the same plant as well as for processes carried out in separate establishments, possibly even managed by different entities. Another aim of the invention is to be able to control in real time the leather treatment process. Another aim of the invention is to promptly optimize the process of 10 skin treatment. Another aim of the present invention is to propose a system which is highly automated. Another aim of the invention is to propose a system that is implementable easily, quickly and at low cost. 15 Another aim of the invention is to propose a system that improves and / or alternative to traditional ones. Another aim of the invention is to propose a system with a alternative characterization, both in functional and implementation terms, compared to traditional ones. 20 SUMMARY OF THE INVENTION All these purposes - whether considered individually or in any their combination - and others that will result from the following description are achieved, according to the invention, with a management system for a plant treatment of leather or similar having the characteristics indicated in the claim 25 1.
