El pegado corte-suela en un zapato es, sin duda, una de las operaciones más problemáticas dentro del proceso de fabricación del calzado. Tanto es así que constituye la causa principal de devoluciones, representando un 25% del total, por lo que este proceso adquiere suma importancia para todos lo fabricantes de calzado.The glued cut-sole on a shoe is undoubtedly one of the most problematic operations within of the shoe manufacturing process. So much so that it constitutes the main cause of returns, representing 25% of the total, so this process acquires great importance for all shoe manufacturers.
En el proceso de fabricación del calzado, es necesario eliminar la parte más superficial de la piel con que se va a fabricar el zapato en aquellas zonas donde ha de realizarse el pegado con el material de piso (suela). El objetivo es alcanzar una capa interna, con suficiente resistencia mecánica y un aspecto superficial (rugosidad) tal, que fortalezca el anclaje con el adhesivo, asegurando una suficiente fuerza de cohesión con la suela. Por tanto, la deficiente realización del lijado genera importantes fallos en la calidad final del zapato, lo que a corto plazo se traduce en pérdidas económicas y de imagen de la empresa.In the shoe manufacturing process, it is it is necessary to remove the most superficial part of the skin with which it leaves to manufacture the shoe in those areas where the glued with the floor material (sole). The goal is to reach a inner layer, with sufficient mechanical strength and an appearance surface (roughness) such that it strengthens the anchor with the adhesive, ensuring sufficient cohesion force with the sole. Therefore, poor sanding performance generates significant failures in the final quality of the shoe, which in the short term is translates into economic losses and image of the company.
Por extensión, el método aquí descrito se puede utilizar para comprobar el grado y regularidad de la preparación por lijado, cardado o similar, de cualquier material que necesita esta preparación antes de cualquier operación (encolado, pegado, acabado, etc.).By extension, the method described here can be use to check the degree and regularity of the preparation by sanding, carded or similar, of any material that needs this Preparation before any operation (gluing, gluing, finishing, etc.).
La presente invención se refiere a un sistema para evaluar el grado de lijado de pieles y o materiales basado en medir la temperatura de la superficie y comprobar la diferencia de temperatura entre las zonas lijadas o cardadas y las no tratadas, cuando la piel o el material es sometido a un calentamiento.The present invention relates to a system to evaluate the degree of sanding of skins and materials based on measure the surface temperature and check the difference of temperature between sanded or carded and untreated areas, when the skin or the material is subjected to heating.
El diverso comportamiento de un material frente a la exposición al calor, dependiendo de su estado superficial, permite diferenciar si ha sido previamente lijado o no. Por tanto, es posible la caracterización de la calidad del lijado usando técnicas basadas en la temperatura superficial.The different behavior of a material versus to exposure to heat, depending on its surface state, it allows to differentiate if it has been previously sanded or not. So, It is possible to characterize sanding quality using techniques based on surface temperature.
En razón de lo anterior, el sistema que la presente invención propone, se basa por tanto en un método diferencial basado en la caracterización térmica de la superficie de un material expuesto a una fuente de calor controlada. Así, se somete el materia a una fuente de calor y se obtiene una imagen térmica del material en su estado inicial, y posteriormente, se obtiene una segunda imagen térmica del mismo material tras el proceso de lijado (o cardado), y sometido a la misma fuente de calor, pudiendo determinarse las diferencias entre ambas imágenes.Because of the above, the system that the The present invention proposes, therefore based on a method differential based on the thermal characterization of the surface of a material exposed to a controlled heat source. Thus subject the matter to a heat source and obtain an image thermal of the material in its initial state, and subsequently, it obtains a second thermal image of the same material after the sanding process (or carding), and subjected to the same source of heat, being able to determine the differences between the two images.
Ello se produce debido a que el proceso de lijado altera las características superficiales, tales como el color, la rugosidad, el grosor, la conductividad, etc., y junto con ellas la distribución de temperaturas alcanzadas en la mencionada superficie. La comparación de ambas imágenes a modo de mapa de temperaturas permite determinar las zonas afectadas por el lijado e, incluso, de forma cualitativa, establecer una gradación de éste.This occurs because the process of sanding alters surface characteristics, such as the color, roughness, thickness, conductivity, etc., and together with they the distribution of temperatures reached in the mentioned surface. The comparison of both images as a map of temperatures allow to determine the areas affected by sanding and, even qualitatively establish a gradation of East.
Para ello, se debe realizar un trabajo previo de caracterización de los materiales implicados en el proceso de producción, de modo que se aporte al sistema informático los datos precisos para decidir sobre la calidad del producto. Se trata de "enseñar" al sistema la diferencia entre cada material en estado original y correctamente preparado (lijado, cardado, etc.) generando un patrón térmico para cada caso, en el que se incluirán las tolerancias que sean precisas.For this, a previous work of characterization of the materials involved in the process of production, so that data is contributed to the computer system precise to decide on the quality of the product. Is about "teach" the system the difference between each material in original state and properly prepared (sanding, carding, etc.) generating a thermal pattern for each case, which will be included the tolerances that are precise.
El método de control de calidad propuesto consiste pues en capturar la imagen térmica del producto antes y después del proceso de preparación. La comparación de ambas imágenes evaluará varios factores decisivos para la determinación de la calidad final:The proposed quality control method It consists in capturing the thermal image of the product before and After the preparation process. The comparison of both images evaluate several decisive factors for the determination of the final quality:
- \bullet?
- Detección de la zona lijada y su ubicación en la superficie total del objeto.Detection of the sanded area and its location on the total surface of the object.
- \bullet?
- Determinación de la profundidad/calidad del lijado atendiendo al patrón correspondiente previamente establecido.Determination of depth / quality of sanding according to the corresponding pattern previously established.
Se trata de determinar si se ha lijado toda la zona implicada en el posterior proceso (pegado, acabado, etc.) y si la calidad del lijado en toda esta superficie se adecua a las especificaciones dadas para el/los material/materiales implicados.It is about determining if all the zone involved in the subsequent process (gluing, finishing, etc.) and if The quality of sanding on this entire surface is adapted to the specifications given for the material / materials involved
Además, se tiene la posibilidad de conocer la temperatura alcanzada en cualquier zona de la superficie y así se puede establecer una comparación más precisa que la simplemente visual.In addition, you have the possibility of knowing the temperature reached in any area of the surface and thus you can establish a more accurate comparison than simply visual.
Por tanto, el sistema para evaluar el grado de lijado de pieles basado en la medida sin contacto de la temperatura superficial, que la presente invención propone, consiste en un conjunto a de dispositivos que permiten aplicar el método de análisis diferencial de imágenes térmicas descrito.Therefore, the system to assess the degree of sanding of skins based on non-contact temperature measurement surface, which the present invention proposes, consists of a set of devices that allow applying the method of differential thermal image analysis described.

La figura 1 representa el diagrama de bloques del sistema según la invención.Figure 1 represents the block diagram of the system according to the invention.
El modo de realización preferente del sistema para evaluar el grado de lijado de pieles basado en la medida sin contacto de la temperatura superficial que la presente invención propone, es el siguiente.The preferred embodiment of the system to evaluate the degree of sanding of skins based on the measurement without surface temperature contact than the present invention proposes, is the following.
En primer lugar con el sistema descrito ensamblado y en posición de funcionamiento, se sitúa la superficie del material a analizar (6) sobre el área de trabajo quedando a una distancia determinada del conjunto calefactor/sensor, por lo que debe disponerse una superficie plana, fija.First with the system described assembled and in operating position, the surface is placed of the material to be analyzed (6) on the work area being at a determined distance of the heater / sensor assembly, so a flat, fixed surface must be provided.
Una vez situado el material (6), el primer paso exige un importante aporte de calor al material (6) a analizar, para lo cual se dispone de una fuente de calor (4) rica en rayos infrarrojos, por ejemplo, unos focos halógenos situados a pocos centímetros de la superficie (6). Se enciende la fuente calorífica (4) y, de manera simultánea, se acciona el motor (2) del sistema de desplazamiento (1) de la propia fuente de calor (4) y del sensor de infrarrojos (3) sobre la superficie (6) del elemento que se desea evaluar.Once the material (6) is located, the first step it requires an important contribution of heat to the material (6) to analyze, for which a heat source (4) rich in lightning is available infrared, for example, halogen bulbs located a few centimeters of the surface (6). The heat source is turned on (4) and, simultaneously, the motor (2) of the power system is driven displacement (1) of the heat source itself (4) and of the sensor infrared (3) on the surface (6) of the desired element evaluate.
Para garantizar el calentamiento de toda la superficie (6) objeto del análisis, se dota de movimiento al elemento calefactor, en el eje horizontal (1), con la ayuda de una guía lineal gobernada por un motor (2) paso a paso. Este motor (2) depende de un microcontrolador (9) previamente programado y que es encargado de determinar la velocidad, el número de pasos y el sentido de giro.To guarantee the heating of all the surface (6) object of the analysis, movement is provided heating element, on the horizontal axis (1), with the help of a linear guide governed by a stepper motor (2). This engine (2) it depends on a previously programmed microcontroller (9) and that is responsible for determining the speed, the number of steps and the turning sense.
El conjunto formado por el calefactor (4) y el sensor pirométrico (3), se montan solidariamente sobre una guía lineal (1) accionada por el motor (2), de tal forma que dicho conjunto se desplace a lo largo de la zona de trabajo. Entre el calefactor (4) y el sensor (3) debe existir un decalaje en el eje longitudinal del movimiento, de manera que se asegure el calentamiento previo de la zona a analizar. El sensor pirométrico (3), situado unos centímetros por encima de la fuente calorífica (4), pero no en la misma vertical, recoge la energía reflejada a través de una óptica de focalización (5) y esta captura de los rayos infrarrojos que emite la superficie (6) de la piel, obteniendo una lectura prácticamente simultánea al calentamiento producido con la fuente de calor.The assembly formed by the heater (4) and the pyrometric sensor (3), are mounted in solidarity on a guide linear (1) driven by the motor (2), such that said set moves along the work area. Between heater (4) and sensor (3) there should be a offset in the shaft longitudinal movement, so as to ensure the preheating of the area to be analyzed. The pyrometric sensor (3), located a few centimeters above the heat source (4), but not in the same vertical, collect the energy reflected to through a focusing optics (5) and this capture of the infrared rays emitted by the surface (6) of the skin, obtaining a reading practically simultaneous to the heating Produced with heat source.
El aporte de calor y el inicio del desplazamiento se controlan desde el dispositivo informático (8) a la vez que el elemento sensor (3) y el control electrónico (9) realizan la lectura y acondicionamiento de señales sobre la zona previamente calentada y la envían al propio dispositivo informático.The heat input and the beginning of displacement are controlled from the computing device (8) to the same time as the sensor element (3) and the electronic control (9) perform the reading and conditioning of signals on the area previously heated and sent to the device itself Person who is dedicated to computer science.
La siguiente fase supone la medición del calor radiado por la propia superficie (6). Para ello, el sistema incluye un sensor de línea pirométrico (3) insertado en un circuito de acondicionamiento, todo ello contenido en una caja metálica provista de una lente de focalización (5) específica para radiación infrarroja, con capacidad de enfoque manual. Este sensor (3) junto con su circuito de acondicionamiento está situado unos centímetros por encima de la fuente calorífica (4), pero no en la misma vertical, sino retrasada de esta fuente escasos centímetros respecto al sentido del barrido y además el conjunto compuesto por el sensor de infrarrojos (3), junto con su circuito de acondicionamiento y la fuente de calor (4), se desplazan solidariamente.The next phase involves the measurement of heat radiated by the surface itself (6). For this, the system includes a pyrometric line sensor (3) inserted in a circuit of conditioning, all contained in a metal box provided of a focusing lens (5) specific for radiation infrared, with manual focus capability. This sensor (3) together with its conditioning circuit is located a few centimeters above the heat source (4), but not in it vertical, but delayed from this source a few centimeters regarding the direction of the scan and also the set consisting of the infrared sensor (3), together with its circuit of conditioning and heat source (4), move in solidarity.
Esta disposición permite, por un lado que el sensor (3) no se vea afectado por la radiación emitida directamente por la fuente de calor (4), sino que captura la que emiten los materiales (6) sometidos al control y por otro permite una lectura prácticamente simultánea al calentamiento producido con la fuente de calor, lo que favorece la aparición de diferencias más extremas de temperatura muy útiles para el objetivo final; de otra manera, si transcurre más tiempo entre el calentamiento y la lectura por parte del sensor, se corre el peligro de que se produzca una homogeneización de la temperatura en la superficie de modo que la diferencia de temperaturas no llega a ser tan apreciable.This arrangement allows, on the one hand that the sensor (3) is not affected by directly emitted radiation by the heat source (4), but captures the one emitted by materials (6) under control and on the other allows a reading practically simultaneous to the heating produced with the source of heat, which favors the appearance of more extreme differences of temperature very useful for the final objective; otherwise, if more time elapses between heating and reading by part of the sensor, there is a danger of a homogenization of the surface temperature so that the temperature difference does not become so appreciable.
Los datos obtenidos por el circuito electrónico del sensor (3), convenientemente pre-tratados, se transfieren vía serie a un dispositivo informático (8) PC+software diseñado al efecto, que construye la imagen térmica (7) basándose en una escala de color escalable que permite trabajar en distintos rangos de temperatura, y se visualizan las zonas de la superficie dónde la temperatura ha alcanzado diferentes valores, permitiendo así la comparación de la imagen de las muestras con una imagen considerada como "patrón".The data obtained by the electronic circuit of the sensor (3), conveniently pre-treated, is transfer via serial to a computer device (8) PC + software designed for this purpose, which builds the thermal image (7) based in a scalable color scale that allows you to work in different temperature ranges, and surface areas are displayed where the temperature has reached different values, allowing So the comparison of the image of the samples with an image considered as "patron".
El elemento sensor (3) y el control electrónico (9) realizan la lectura y acondicionamiento de señales sobre la zona previamente calentada y la envían al propio dispositivo informático.The sensor element (3) and the electronic control (9) perform the reading and conditioning of signals on the previously heated area and send it to the device itself Person who is dedicated to computer science.
Al finalizar el recorrido programado se procede al apagado de la fuente de calor (4) y el retorno del conjunto fuente-sensor (4) y (3) al punto de origen, para así poder realizar una nueva evaluación.At the end of the scheduled tour, proceed when the heat source is turned off (4) and the return of the assembly source-sensor (4) and (3) to the point of origin, so Be able to perform a new evaluation.
Alternativamente, puede montarse el conjunto calefactor/sensor sobre un bastidor fijo, de manera que sea la superficie de apoyo de los elementos a analizar la que se desplace, en forma de cinta transportadora o similar.Alternatively, the assembly can be mounted heater / sensor on a fixed frame, so that it is the surface of support of the elements to analyze the one that moves, in the form of a conveyor belt or similar.
