DESCRIPCIONDESCRIPTION
Procedimiento para unir bordes de paneles de mueblesProcedure to join edges of furniture panels
La presente invencion se refiere a un procedimiento de acuerdo con la reivindicacion 1 para el encolado de bordes de paneles de muebles aplicables a muebles vitrinas.The present invention relates to a process according to claim 1 for gluing edges of furniture panels applicable to display cabinets.
Los muebles vitrina consisten en un conjunto de paneles de muebles, que constituyen las paredes y frentes del mueble, acopladores, es decir, tornillos o vastagos y varios otros elementos, tales como sujeciones o patas.The showcase furniture consists of a set of furniture panels, which constitute the walls and fronts of the furniture, couplers, that is, screws or stems and several other elements, such as fasteners or legs.
Los paneles de muebles de muebles vitrina se fabrican a partir de paneles de aglomerado (paneles de partfculas) del tipo MDF o HDF. Las principales areas frontales de los paneles de aglomerado se cubren con un material de revestimiento tal como chapa de madera, laminado de madera o lamina de metal. Los paneles de aglomerado se cortan para coincidir con las dimensiones requeridas del panel de mueble final, y los bordes de los paneles de muebles se unen con una cubierta de borde tal como cinta o lamina de metal. La cubierta de borde se une con el panel mediante una cola adecuado, que se calienta normalmente cuando se aplica sobre la superficie del borde. Un ejemplo del procedimiento del estado de la tecnica se proporciona en el documento DE 196 15 879.Furniture showcase furniture panels are manufactured from chipboard panels (particle panels) of the MDF or HDF type. The main front areas of the agglomerate panels are covered with a cladding material such as wood veneer, wood laminate or metal sheet. The agglomerate panels are cut to match the required dimensions of the final furniture panel, and the edges of the furniture panels are joined with an edge cover such as tape or sheet metal. The edge cover is attached to the panel by a suitable glue, which is usually heated when applied to the edge surface. An example of the prior art procedure is provided in DE 196 15 879.
En la produccion de gran volumen de paneles de muebles, en la que los paneles se unen a altas velocidades, se pueden producir defectos de fabricacion, tales como el encolado impreciso de los bordes por el material de cubierta o una cantidad excesiva de cola en la region del borde. Los defectos de fabricacion son causados por la diversa calidad de la materia prima de la capa interior del panel de aglomerado.In the production of large volume of furniture panels, in which the panels are joined at high speeds, manufacturing defects can occur, such as inaccurate gluing of the edges by the cover material or an excessive amount of glue in the edge region. Manufacturing defects are caused by the different quality of the raw material of the inner layer of the chipboard panel.
Por ejemplo, los paneles fabricados de comfera tienen propiedades ffsicas diferentes de los paneles a base de madera dura. Si la capa interior de paneles de muebles se fabrica de material reciclado, los paneles del mismo lote de produccion pueden tener diferentes propiedades.For example, panels made of comfera have physical properties different from hardwood-based panels. If the inner layer of furniture panels is made of recycled material, the panels of the same production lot may have different properties.
El objetivo de presente invencion es desarrollar un procedimiento para encolar bordes de paneles de muebles, que proporcione una alta precision de acabado en los bordes de paneles de muebles con diferentes propiedades de la capa interior, proporcionando un uso optimo de la cola.The aim of the present invention is to develop a method for gluing edges of furniture panels, which provides a high precision of finishing at the edges of furniture panels with different properties of the inner layer, providing optimum use of the glue.
El objeto de la presente invencion es un procedimiento para encolar bordes de paneles de muebles que comprenden una capa interior de virutas, en el que una cubierta de borde se une con el panel de mueble por medio de una cola calentado a una cierta temperatura, en el que el volumen y la temperatura de la cola se ajustan individualmente para cada borde encolado, dependiendo de los parametros de la materia prima de la capa interior de virutas determinados por un analizador de la imagen de la capa interior de virutas.The object of the present invention is a method for gluing edges of furniture panels comprising an inner layer of shavings, in which an edge cover joins with the furniture panel by means of a glue heated to a certain temperature, in that the volume and temperature of the glue are adjusted individually for each glued edge, depending on the parameters of the raw material of the inner layer of chips determined by an image analyzer of the inner layer of chips.
Preferentemente, la imagen del borde de la capa interior de virutas que se va a encolar se compara mediante el analizador de la imagen de la capa interior de virutas con un conjunto de imagenes de referencia almacenadas en una base de datos de referencia, en la que la imagen que es mas similar a la imagen del borde del mueble que se va a encolar se selecciona, y, posteriormente, el volumen de cola y su temperatura se ajustan de acuerdo a los datos especificados para la imagen de referencia seleccionada.Preferably, the image of the edge of the inner chip layer to be glued is compared by the image analyzer of the inner chip layer with a set of reference images stored in a reference database, in which The image that is more similar to the image of the edge of the piece of furniture to be glued is selected, and subsequently, the volume of the tail and its temperature are adjusted according to the data specified for the selected reference image.
Preferentemente, por medio del analizador de la capa interior de virutas se determina al menos un parametro de la imagen del borde de la capa interior de virutas, seleccionada de un grupo que contiene: brillo medio de las virutas, tamano medio de las virutas, variaciones en el brillo y tamano de las virutas particulares, distribucion del tamano de las virutas, tamano de los espacios vados entre virutas.Preferably, at least one parameter of the image of the edge of the inner layer of chips is selected by means of the analyzer of the inner chip layer, selected from a group containing: average chip brightness, average chip size, variations in the brightness and size of the particular chips, distribution of the size of the chips, size of the empty spaces between chips.

La Figura 3 presenta un diagrama de una lmea de procedimiento para el encolado de bordes de paneles muebles de acuerdo con la invencion. Los paneles se alimentan desde el puesto 201 mediante un transportador hasta un puesto 202 de corte y fresado, en el que los paneles de panel de aglomerado se cortan para coincidir con las dimensiones requeridas del panel de mueble, y los bordes de los paneles se forman adecuadamente. A continuacion, los parametros de la materia prima de la capa interior se determinan en el puesto 203 de analisis de la capa interior.Figure 3 presents a diagram of a process line for gluing edges of movable panels according to the invention. The panels are fed from post 201 by a conveyor to a cutting and milling station 202, in which the agglomerate panel panels are cut to match the required dimensions of the furniture panel, and the edges of the panels are formed adequately. Next, the parameters of the raw material of the inner layer are determined at position 203 of analysis of the inner layer.
El puesto 203 de analisis esta equipado con una camara, que captura una imagen del borde del panel alimentado por el transportador. Los parametros del material de la capa interior se pueden determinar mediante dos procedimientos.The analysis station 203 is equipped with a camera, which captures an image of the edge of the panel fed by the conveyor. The parameters of the inner layer material can be determined by two procedures.
El primer procedimiento se realiza mediante la comparacion de la imagen del borde del panel de mueble que se va a encolar con imagenes de una base 204 de datos de referencia. Por ejemplo, la base 204 de datos puede almacenar, para cada materia prima a analizar, un conjunto de imagenes que ilustran el aspecto del panel, pre-determinadas por un operario del sistema. El puesto 203 de analisis, que utiliza algoritmos para la comparacion de la imagen y para determinar la similitud de imagen, determina la imagen de la base 204 de datos de referencia, que es mas similar a la imagen el panel alimentado por el transportador y determina, por tanto, el tipo de la materia prima.The first procedure is performed by comparing the image of the edge of the furniture panel to be glued with images of a reference database 204. For example, database 204 may store, for each raw material to be analyzed, a set of images illustrating the appearance of the panel, pre-determined by a system operator. The analysis station 203, which uses algorithms for the comparison of the image and to determine the image similarity, determines the image of the reference database 204, which is more similar to the image the panel fed by the conveyor and determines , therefore, the type of the raw material.
En el otro procedimiento, el analisis de la imagen se realiza mediante la definicion de los parametros de imagen, tal como el brillo medio de las virutas, el tamano medio de las virutas, variaciones en brillo y tamano de las virutas particulares, la distribucion de tamano de las virutas, espacios vados entre virutas, etc. Tales parametros se utilizan para definir el material de la capa interior del panel, el nivel de compactacion, el contenido de material reciclado y otros parametros, que son necesarios para determinar los parametros del procedimiento para el encolado de los bordes de paneles de muebles.In the other procedure, the image analysis is performed by defining the image parameters, such as the average brightness of the chips, the average size of the chips, variations in brightness and size of the particular chips, the distribution of chip size, empty spaces between chips, etc. Such parameters are used to define the material of the inner layer of the panel, the level of compaction, the content of recycled material and other parameters, which are necessary to determine the parameters of the process for gluing the edges of furniture panels.
El conocimiento de los parametros del material de la capa interior permite determinar los parametros del procedimiento de encolado de la cubierta de borde, que se realiza en el puesto 205, en el que dos bordes paralelos se someten al procedimiento de encolado. Allf se ajusta, al menos, el volumen de la cola que se alimenta por el alimentador 206 de cola y el punto de fusion de la cola que se calienta con el calentador 207. Por ejemplo, para encolar los bordes de panel con una lamina de metal que tiene un espesor de 0,4 mm por medio de la difusion de cola de fusion, granulado, una cola ejemplar es MELT EB 1756 fabricado por Follmann & Co, Minden, Alemania se puede utilizar con los siguientes parametros de procedimiento:The knowledge of the parameters of the material of the inner layer makes it possible to determine the parameters of the gluing procedure of the edge cover, which is carried out at position 205, in which two parallel edges are subjected to the gluing procedure. There, at least, the volume of the tail that is fed by the tail feeder 206 and the melting point of the tail that is heated with the heater 207 are adjusted. For example, to glue the panel edges with a sheet of Metal having a thickness of 0.4 mm by means of the diffusion of fusion tail, granulated, an exemplary tail is MELT EB 1756 manufactured by Follmann & Co, Minden, Germany can be used with the following process parameters:
- para la capa interior que se muestra en la Figura 2E y en la Figura 2B: la temperatura de la cola debera ser de 195 a 200°C y el volumen de cola debera ser de 100-115 g/m2- for the inner layer shown in Figure 2E and Figure 2B: the tail temperature should be 195 to 200 ° C and the tail volume should be 100-115 g / m2
- para la capa interior que se muestra en la Figura 2F la temperatura de la cola debera ser de 190-195°C y el volumen de cola debera ser de 100-115 g/m2- for the inner layer shown in Figure 2F, the temperature of the glue should be 190-195 ° C and the volume of the glue should be 100-115 g / m2
- para la capa interior que se muestra en la Figura 2D la temperatura de la cola debera ser de 200-205°C y el volumen de cola debera ser de 85-90 g/m2- for the inner layer shown in Figure 2D, the temperature of the glue should be 200-205 ° C and the volume of the glue should be 85-90 g / m2
- para la capa interior que se muestra en la Figura 2A y Figura 2C la temperatura de la cola debera ser de 190- 195°C y el volumen de cola debera ser de 85-90 g/m2- for the inner layer shown in Figure 2A and Figure 2C the tail temperature should be 190-195 ° C and the tail volume should be 85-90 g / m2
El panel se transporta con una mesa 208 giratoria, que lo hace girar en un angulo de 90°, hasta el proximo puesto 209 de corte y fresado para procesar los dos bordes restantes del panel, en la misma forma que en el puesto 202. Despues, los bordes se unen en un puesto 210 de encolado equipado con un alimentador 211 de cola y un calentador 212, para lo que los parametros del procedimiento se definen en la misma forma que para los puestos 205-207. Los paneles encolados se recogen en un puesto 213 de recogida.The panel is transported with a rotary table 208, which rotates it at a 90 ° angle, to the next cutting and milling position 209 to process the two remaining edges of the panel, in the same way as at position 202. Then , the edges are joined in a gluing station 210 equipped with a tail feeder 211 and a heater 212, for which the process parameters are defined in the same way as for positions 205-207. The glued panels are collected at a collection station 213.
El procedimiento de la presente invencion permite la supervision continua del procedimiento de encolado de bordes de paneles y el ajuste de los parametros del procedimiento para una materia prima particular de la capa interior de virutas de paneles de muebles. Por lo tanto, el volumen de cola utilizado en el procedimiento y la energfa suministrada para calentar la cola se optimiza, lo que da como resultado la reduccion de los costes de produccion, la reduccion de cantidad de sustancias nocivas (cola) contenidas en las paneles fabricados y la buena calidad del encolado de borde, asf como la prevencion de fugas de cola en los bordes de paneles.The process of the present invention allows continuous supervision of the method of gluing panel edges and the adjustment of the process parameters for a particular raw material of the interior layer of furniture panel chips. Therefore, the volume of glue used in the procedure and the energy supplied to heat the glue is optimized, which results in the reduction of production costs, the reduction of the amount of harmful substances (glue) contained in the panels manufactured and the good quality of edge gluing, as well as the prevention of tail leaks at the edges of panels.
