The present invention operates in the field of industrial processes of washing and re-certification of garments, such as high visibility garments for operators who perform high-risk jobs on roads and highways. In particular, the present invention regards a new and innovative method for identifying the garment and for certifying the same through a completely automatic system that allows a quick adaptation to the current laws or specific requests of the client.
Safety laws are continuously evolving. In particular, in order to protect the safety of some worker categories, predetermined clothing is obligatory. Often, in fact, it is possible to see firemen, mailmen, employees of the highway management company, road police agents, etc. who wear fluorescent garments with reflector bands. In this manner, even in foggy or rainy conditions, or in any case in poor visibility conditions, wearers present on the road will always be identifiable by drivers who drive in proximity thereto.
It is obvious that each high visibility garment must have parameters predetermined by local or company law in order to be worn by this category of workers.
After each wash, therefore, it is necessary that the garment be newly certified, i.e. the subject who performs the industrial washing must verify that the fabric still has the minimal characteristics in order to have the aforesaid parameters of colorimetry and reflectance.
The 1999 patent EP 1 004 879 has framed the problem and proposed some effective solutions. The object of this patent is a system for acquiring the image of the garment after washing and its comparison with an approved specimen. A dedicated software, at this point, compares each pixel of the two images (that of the specimen and that of the garment under examination) and, in the end, gives feedback on whether the garments comply with the legal parameters.
Such procedure, even if much improved with respect to the preceding re-certification practices, has critical issues that the present patent intends to remedy.
First of all, the patented system obliges the constant presence of an operator at the site of the image acquisition, since an automated system is not provided for sorting the garments deemed suitable from those which do not comply with the parameters. From the colorimetric and spectrophotometric analysis, the system is able to calculate the total surface corresponding to specific parameter characteristics, and in the case of the law 20471, certify the conformity thereof.
Secondly, there is absolutely no system that allows the identification of the garment in its entirety. In many cases, in fact, the wearer must wear both a vest or jacket and pants. The possibility to associate the two garments, during acquisition and processing of the image, would allow being able to control that the entire outfit is in accordance with parameters required by possible modifications to the law and that the sum of the acceptable areas of both garments comply with possible new law requirements. In the case of developments of current law—and without the possibility to sum the garments—with the systems known at the state of the art, many garments could be uselessly discarded.
The analysis of the single garment, without the possibility of identifying it and associating it with other garments simultaneously worn by the wearer, still allows controlling the compliance of small-size garments (S-XS-XXS) with legal parameters, the limited surface of such garments making them more easily positionable at the lower parameter limits. The analysis of the complete outfit of the wearer—currently not existing—would lead to a higher lifetime of the garments, preventing the useless discarding and/or destruction thereof.
Finally, among the critical issues of the systems currently in use, there is no possibility to adjust the parameters according to which a garment is approved or rejected. National and company laws are continuously evolving and they pursue increasingly high safety standards. With the current systems, a change of the law would require resetting and re-installing the software on which the operation of the entire control and/or recertification plant is based. The object of the present patent is therefore that of overcoming these and other critical issues existing in the systems currently used for controlling and/or recertifying garments or accessories.
According to the present invention, a system is attained for analyzing several particular types of garments, in particular high visibility garments, effectively resolving the abovementioned problems.
In addition, the present invention is effectively applied to any type of garment that requires a colorimetric analysis and a calculation of the total surface.
Among the main advantages of the present invention, it should be underlined that the current modes of measuring colorimetric and reflecting characteristics are surpassed; up to now, these have been carried out with instruments such as retroreflectometers and spectrophotometers, through thousands of single measurements for the calculation of the compliant surface.
Advantageously, the present invention makes use of a dedicated software which is adapted to analyze the morphological, metrical and colorimetric state of a garment or an accessory. More in detail, said software, unlike those known up to now, is suitable to overall assess the colorimetric aspects of the garment being analyzed. As global assessment, moreover, it is intended its analysis associated with the size of the garment and with other garments that are worn by the same user. In the case of a work uniform including jacket and pants, it is in fact possible that the single garments are not suitable according to the parameters to be respected—if they are taken separately—while an analysis associated with the other garment could lead to a positive test result.
Said analysis is carried out inside a tunnel, provided with a power supply source and with at least one pair of image capturing devices.
Advantageously, the light source can be constituted by a lamp or a plurality of lamps of any type, such as halogen lamps, LED lamps, UV or IR illuminators, laser lights or the like.
Also the image capturing devices, advantageously, are constituted by cameras or video cameras available on the market, such as CCD video cameras, CMOS video cameras, IR or UV sensors, laser sensors or the like. Said image capturing devices, more specifically, are at least one pair including a front device and a rear device adapted to respectively take a photograph of the front part and a photograph of the rear part of the garment to be analyzed and to send said photographs to the software for the processing thereof.
For the purpose of ensuring that the analysis reaches maximum reliability levels, advantageously, a common automatic gripping mechanism is arranged inside said tunnel. At the time of entry of the garment in the tunnel, said mechanism grips several pre-established strips of the garment to be analyzed and places the latter in a spread configuration. In this manner, substantially the entire surface of the garment to be analyzed is hit by the light of the light source and is visible by said image capturing devices. Of course, at the end of the image capture, said automatic gripping device is adapted to release the gripped strips, returning the garment to the initial configuration.
Advantageously, said tunnel is constituted by a fixed or removable structure in which each garment or the plurality of garments worn by the same wearer remain for a period of time necessary for capturing the images. In some cases, said tunnel can be made in a manner so as to constitute an actual darkroom, in which the light of the outside environment does not at all filter into said tunnel.
In the latter case, advantageously, in order to preserve the functionality of all the components thereof, at least one temperature sensor, preferably a plurality of temperature sensors is placed at the interior of said tunnel. These communicate the interior temperature of the tunnel to the software which, upon exceeding a predetermined threshold value, automatically and reversibly activates a forced ventilation system within the tunnel.
In a preferred embodiment, said tunnel is at its interior also provided with an exposure meter and/or a luxmeter, adapted to monitor the interior brightness in said tunnel in order to control the suitability of the internal light source. Said exposure meter and/or said luxmeter are advantageously also adapted to ensure the absence of light interferences from one image capture step to the next.
The garments to be analyzed, within the system that is the object of the present invention, are moved by a common mechanical movement system advantageously constituted by an entry track, which introduce the garments to the interior of the tunnel, a track inside said tunnel, which the garments remain for the time necessary for capturing the images, and by a pair of exit tracks. In this manner, advantageously, the garments which have been approved in assessment step are sorted from those which have been rejected in assessment step by means of two different channels.
Advantageously, each garment is provided with an identification device, preferably constituted by common barcode readers or RFID readers. Outside or inside the tunnel, a corresponding identification sensor is advantageously placed that is adapted to recognize the garment or the plurality of garments corresponding to the same wearer for a global assessment.
The assessment of the garments takes place according to the following steps:
Advantageously, in a preferred version of the present invention, the system is also provided with at least one common display, preferably touch-screen, which acts as a communication interface between the software and the operator for managing and/or controlling the system. Some functionalities offered by the display can be, by way of a non-limiting example, the display of the images that are the object of analysis, the graphic image of which surfaces are deemed suitable and which are not with respect to the analysis parameters, etc.
Advantageously, due to its characteristics, the present system allows complete operative autonomy without any operator having to be physically present during the operation thereof. One of the main characteristics that makes the use of the present system particularly advantageous, also in terms of possible future uses, lies in the possibility to modify the parameters according to which a garment is approved or rejected. This will be possible due to a simple knob arranged inside or in proximity to the tunnel or, even more advantageously, through any one adjustment system integrated in the display just described and in said software.
A more complete embodiment of the present invention, with accessories, provides for supplying an App for electronic devices downloadable by all wearers, which allows them to identify their own garment (through said identification device) and to have access to the data present in a memory regarding at least the most recent assessment obtained from the garment identified by the dedicated software.
Possibly, said App may advantageously enable the display of the chronology of the garment images captured in the various image acquisition steps conducted, of the chronology of the assessments of said identified garment and the position at every instant of such garment in the production process.
The advantages offered by the present invention are evident in light of the description set forth up to now and will be even clearer from the enclosed figures and relative detailed description.
The invention will be described hereinbelow in at least one preferred embodiment by way of a non-limiting example with the aid of the enclosed figures, in which:
The present invention will now be illustrated merely by way of a non-limiting or non-constraining example, with the aid of the figures which illustrate several embodiments with regard to the present inventive concept.
With reference to
The represented garment is a jacket, but the system described in detail hereinbelow is suitable to analyze and to assess any type of garment, even special garments, especially suitable for high visibility such as vests, jackets, pants, gloves, hats or any other garment suitable to instantly identify a wearer even in poor visibility conditions.
The garments are transported inside the tunnel 100 by a common movement system 40, preferably configured with tracks. In particular, as better represented in
Returning to the technical specifications of the plant according to the present invention, said tunnel 100 can be constituted by a fixed or disassemblable structure and, if the situation required it, it can be completely closed, or made as an actual darkroom in which the light of the external environment cannot in any manner filter inside.
In this particular embodiment, in order to preserve the correct operation of all the components of the system inside the tunnel 100, at least one temperature sensor 90 is adapted, upon exceeding a predetermined temperature inside the tunnel 100, to reversibly activate a common forced ventilation system 91. As an addition to this embodiment, in order to ensure the constant brightness intensity at the time of acquisition of the images and/or detection of the measurements, the internal space of said tunnel 100 is provided with at least one exposure meter and/or luxmeter, which by interfacing the detected data with said software 70, is used for monitoring the light intensity inside the tunnel 100 and adjusting it through suitable potentiometers.
The equipment inside the tunnel 100, which allows the correct performance of all the steps necessary for the assessment, includes apparatuses commonly available on the market: said light source 10 is constituted by at least one, preferably two or in any case a plurality of common lamps available on the market, such as halogen lamps, LED lamps led, UV or IR illuminators, laser lights or the like. The image capturing devices 20-20′ must be positioned in a manner such that at least one front image capturing device 20 is suitable to take a photograph of the front part of the garment and at least one rear image capturing device 20′ is suitable to take a photograph of the rear part of the garment. Also with reference to these devices, they are constituted by common CCD video cameras, CMOS video cameras, IR or UV sensors, laser sensors or the like.
Still inside said tunnel 100, a common automatic gripping mechanism is arranged which is suitable to grip several strips of the garment to be analyzed in order to reversibly arrange it in a spread configuration, in which substantially the entire surface of said garment to be analyzed is exposed to the light of said light source 10, and it can be photographed by said image capturing devices 20-20′. In this manner, the availability of the garment to be analyzed by the image capturing devices 20-20′ and hence by the dedicated software 70 is improved, consequently improving the reliability of the assessment.
As represented in
Often, such high visibility garments are worn in a manner associated with other garments (jacket-pants outfit or in association with gloves or hat). In this case, the identification system will be suitably configured to ensure that the identification sensor 31 is able to associate the garments worn by the same wearer. In this case, their analysis and assessment could also be carried out at the same time.
The procedure of assessment of a garment or of a plurality of garments corresponding to the same wearer are:
Still with reference to
In addition, said display 50 can be suitable to enable the display of the images captured in said image acquisition step (C) and to provide a scheme of which surfaces of said garment, or of said plurality of garments corresponding to the same wearer, correspond to said pre-set parameters.
The knob or any other adjustment device 60, finally, has a fundamental role in managing the analysis. Indeed, it is adapted to adjust the colorimetry parameters according to which a garment is approved or rejected, thus making the system extremely flexible and personalizable.
An additional item that the present invention offers in its preferred embodiment, to all wearers provided with an electronic device such as a smartphone or a tablet, is the possibility to download an App.
Through this application (App), the recognition of each garment is enabled through said recognition device 30 and the access to the memory 80 regarding the identified garment is also enabled. Among the data that the wearer will be able to consult, by way of a non-limiting example, is that regarding the most recent assessment obtained from the identified garment, the chronology of the images of the garment and of the assessments thereof and the position at every instant of the wearer's garment in the production process.
Finally, it is clear that modifications, additions or variations can be made to the invention described up to now that are obvious for a man skilled in the art, without departing from the protective scope provided by the enclosed claims.
