Procedimiento de proteccion de bordes de paneles de muebles y panel de mueble con bordes protegidosEdge protection procedure for furniture panels and furniture panel with protected edges
La presente invencion se refiere a un procedimiento de acuerdo con la reivindicacion 1 para proteger bordes de paneles de muebles aplicables a muebles vitrina, y a un panel de mueble de acuerdo con la reivindicacion 3.The present invention relates to a method according to claim 1 for protecting edges of furniture panels applicable to display cabinet furniture, and to a furniture panel according to claim 3.
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 partmulas) 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 encolan con una cubierta de borde tal como cinta o lamina de metal. La cubierta de borde se encola con el panel mediante una cola adecuada, 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 glued with an edge cover such as tape or sheet metal. The edge cover is glued to the panel by a suitable glue, which is normally 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 encolan 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. 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. Los paneles con bordes encolados defectuosos son considerados como defectuosos y, por tanto, no estan a la venta. La cubierta de borde se tiende a separar cuando se utiliza muy poco de cola para encolar la cubierta. Sin embargo, un exceso de cola da como resultado una apariencia antiestetica del panel final, lo que es inaceptable por los clientes.In the production of large volume of furniture panels, in which the panels are glued 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. 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. Panels with defective glued edges are considered defective and, therefore, are not for sale. The edge cover tends to separate when too little glue is used to glue the cover. However, an excess of glue results in an unsightly appearance of the final panel, which is unacceptable by customers.
El objetivo de la presente invencion es proporcionar un procedimiento para proteger bordes de paneles de muebles, que proporcione una alta precision de la proteccion de todos los bordes de paneles de muebles ofrecidos a los clientes.The aim of the present invention is to provide a method for protecting edges of furniture panels, which provides a high precision of the protection of all the edges of furniture panels offered to customers.

La Figura 3 presenta esquematicamente un diagrama de la lmea de procedimiento para la proteccion de los bordes de paneles de muebles con el procedimiento de acuerdo con la invencion. Por medio del puesto 301 de alimentacion, una panel de gran dimension, por ejemplo, de 5600x2180 mm, revestido con las capas exteriores de lamina de metal, se transporta por el transportador 302 de rodillos hasta el puesto 303 de aserrado transversal, en el que la panel se corta para hacerlo coincidir con las dimensiones requeridas del panel final, que tiene una longitud igual a un multiplo de la longitud estandar de los paneles. El panel se transporta a continuacion hasta un puesto 305 de aserrado longitudinal mediante un transportador 304 de rodillos, para cortar el panel en tiras que tienen una anchura de una anchura bruta del panel de mueble deseado y una longitud igual a un multiplo de la longitud del panel de mueble que se va a producir. Las tiras de panel se transportan por un transportador 306 de entrada hasta un puesto 307 de encolado y formateo en dos lados, en el que el panel se corta para hacerlo coincidir con las dimensiones requeridas del panel final, y se forma el borde del panel. Despues, los bordes del panel se encolan con la cubierta de borde utilizando cola con adicion de un agente fluorescente.Figure 3 schematically presents a diagram of the process line for the protection of the edges of furniture panels with the method according to the invention. By means of the feeding post 301, a large panel, for example, 5600x2180 mm, coated with the outer layers of metal foil, is transported by roller conveyor 302 to the cross-sawing post 303, in which The panel is cut to match the required dimensions of the final panel, which has a length equal to a multiple of the standard length of the panels. The panel is then transported to a longitudinal sawing station 305 by means of a roller conveyor 304, to cut the panel into strips that have a width of a gross width of the desired furniture panel and a length equal to a multiple of the length of the furniture panel to be produced. The panel strips are transported by an input conveyor 306 to a gluing and formatting station 307 on two sides, in which the panel is cut to match the required dimensions of the final panel, and the edge of the panel is formed. Then, the edges of the panel are glued with the edge cover using glue with the addition of a fluorescent agent.
Por ejemplo, para pegar la cubierta de borde se puede utilizar adhesivo de fusion en caliente granulado, por ejemplo MELT EB 1756 fabricado por Folloman & Co, Minden, Alemania, con la adicion del 1% en peso de polvo de fluorescema.For example, to bond the edge cover, granulated hot melt adhesive can be used, for example MELT EB 1756 manufactured by Folloman & Co, Minden, Germany, with the addition of 1% by weight of fluorescema powder.
Las placas con bordes protegidos se inspeccionan por un analizador 308 de la lmea de encolado, que esta equipado con una camara, un sistema de procesamiento de imagenes y una lampara 309 UV, que se intensifica la visibilidad de las lmeas de encolado que se extienden mas alla de los bordes del panel entre la capa de borde y la capa exterior. El sistema de procesamiento de imagenes analiza la imagen capturada por la camara y comprueba despues la uniformidad de la lmea de encolado a lo largo de los bordes del panel. Cuando se nota una desviacion de la lmea 201 de encolado a partir de una lmea recta, es decir, la desaparicion parcial de la lmea de encolado en los bordes 203 del panel como se muestra en la Figura 2B o salidas de la cola como se muestra en la Figura 2C, el analizador 308 indica una inconsistencia en el rendimiento de la lmea de encolado del borde. El panel con bordes protegidos defectuosos se somete a un re-procesamiento y no se lleva al cliente final.The plates with protected edges are inspected by an analyzer 308 of the glue line, which is equipped with a camera, an image processing system and a 309 UV lamp, which intensifies the visibility of the glue lines that extend further beyond the edges of the panel between the edge layer and the outer layer. The image processing system analyzes the image captured by the camera and then checks the uniformity of the gluing line along the edges of the panel. When a deviation of the sizing line 201 is noticed from a straight line, that is, the partial disappearance of the sizing line at the edges 203 of the panel as shown in Figure 2B or tail exits as shown In Figure 2C, the analyzer 308 indicates an inconsistency in the performance of the edge sizing line. The panel with faulty protected edges undergoes reprocessing and is not taken to the end customer.
Los paneles encolados se transportan por un transportador 310 de salida, que puede ordenar los paneles como encolados correcta o incorrectamente. Los paneles encolados correctamente se transportan a un puesto 311 de embalaje, en el que los embalajes se cortan con una sierra 3012 transversal de embalajes a la longitud del elemento de mueble final, y se apilan a continuacion en un puesto 312 de apilamiento y recogida.The glued panels are transported by an exit conveyor 310, which can order the panels as glued correctly or incorrectly. The correctly glued panels are transported to a packing station 311, in which the packages are cut with a cross-sectional saw 3012 from the length of the final piece of furniture, and then stacked in a stacking and collection station 312.
