Definitions
- the present invention relates to a tool allowing the realization of flooring by fixing straight boards or curved on a support by providing a space between the boards to make a joint.
- This tooling allows curvature and thickness adjustments to produce products whose curvature and thickness conform to a pre-established measurement.
- the press is designed in such a way that it can be used at any load between empty press and at full load thanks to the bracing between the pads (f) without damage to its structure and while maintaining a quality of optimal bonding with a sufficient pressing pressure, determined according to the characteristics of the products to be bonded and the adhesives used. Extraction can be facilitated ( fig 6) (fig7 ) by overpressurizing an area (s) in the platen (b) of the press so that the upper part of the platen of the press (j) is lifted ( fig 7 ) while the pads (f), fixed to the lower part of the plate (b) remain fixed, this causing the release of the boards (c) and the plate of the press.
- the holding and spacing parts (I) (m) are set in motion in the guides (k) by the action of systems allowing a controlled thrust such as, for example, pneumatic or hydraulic cylinders (g).
- a simplified variant of the press for bending can be manufactured keeping exactly the same principle of operation but simplifying its implementation.
- the press no longer has two trays (a) (b) facing each other but only one plate (a) on which is positioned the support (d) on which the boards (c) must be fixed by example by gluing.
- This press is provided with a device for maintaining or constraining the boards to the desired position or curvature for the time necessary for their fixing on the support (d).
- the guiding of the boards (c) parallel to the support (d) on which the boards (c) must be fixed, during the bending phase and the pressing of the boards (c) on the support (d) for fixing after the bending phase is made by rails arranged opposite the plate (a).
- the devices for actuating the rails may be for example cylinders, cams or also a device for evacuation of air from the area between the plate (a) and the rails.
- These rails are in sufficient number to allow a uniform pressure on the boards (c) to allow proper fixing on the support.
- These rails will generally be arranged in a transverse or radial axis relative to the longitudinal axis of the boards (c) but may if necessary be arranged in any axis parallel to the plate (a).
- the rails (k) may or may not carry carriages (h) (i) as previously described to ensure the spacing of the boards. If the rails do not carry carriages provided with spacing studs, the constant spacing during the entire bending phase can be obtained by arranging wedges calibrated between the boards. These spacer blocks can then be removed once the fixing of the boards on the support made.
- the bending can be achieved by any means for generating a force in the bending plane for example one or pneumatic cylinders, hydraulic or screw.
- the cylinders can be carried by the pressing rails.
- the plate (a) and the portion of the press supporting the rails for guiding and pressing can be made integral and maintained during the bending phase of the boards (c) by the depression of a zone ( r), either at the periphery (r) of the plate (a), or at the lengths of the plate (a) perpendicular to the axis of displacement of the boards.
- the rails allowing the guiding and pressing of the boards can be maintained in relation to the plate (a).
- the force generated by the depression is sufficient to allow the implementation in good conditions mechanisms for bending and pressing.

Abstract
Description
La présente invention concerne un outillage permettant la réalisation de planchéiage par fixation de planches droites ou courbées sur un support en ménageant un espace entre les planches pour réaliser un joint. Cet outillage permet des réglages de courbure et d'épaisseur afin d'obtenir des produits dont la courbure et l'épaisseur sont conformes à une mesure préétablie.The present invention relates to a tool allowing the realization of flooring by fixing straight boards or curved on a support by providing a space between the boards to make a joint. This tooling allows curvature and thickness adjustments to produce products whose curvature and thickness conform to a pre-established measurement.
Ces produits sont habituellement réalisés planche après planche, ou grâce à des outillages dédiés à chaque type de réalisation, comme c'est le cas dans le brevet déposé par la société Moody où un moule spécifique à chaque produit permet la mise en place des planches et leur maintient le temps nécessaire au collage sur un support sur la face inférieure du planchéiage. Le défaut de ces systèmes est un temps de mise en place des planches important et pour le deuxième un coût important des moules et une mise en oeuvre très contraignante.These products are usually made plank after board, or with tools dedicated to each type of embodiment, as is the case in the patent filed by the company Moody where a mold specific to each product allows the establishment of boards and maintains the time required for gluing on a support on the underside of the flooring. The lack of these systems is a time of implementation of boards important and for the second a significant cost of the molds and a very restrictive implementation.
Des presses pour le collage de planches ou panneaux sont divulguées, par exemple, dans
Le système d'outillage selon l'invention se présente comme une presse composée de deux plateaux (a)(b) en vis-à-vis. L'un des plateaux (a) porte le support (d) sur lequel les planches (c) doivent être collées, l'autre plateau (b) porte les planches (c) et permet si nécessaire de les cintrer à un galbe prédéfini. Le plateau (a) qui presse sur le support (d) peut être doté d'un système à dépression permettant le transport du support (d) avant collage et l'extraction du support (d) et des planches (c) une fois le collage réalisé, ainsi que le déplacement du résultat du collage. Le plateau (a) qui presse sur le support (d) peut recevoir sur sa face inférieure des entretoises amovibles (e), par exemple des feuillards métalliques, disposées sur le support (d) au dessus de la face qui doit être collée sur les planches (c) et permettant pendant la première phase du pressage la translation des planches (c) sous le support (d) sans qu'il y ait de friction entre les planches (c) et le support (d). De la sorte les planches (c) peuvent être cintrées sous le plateau (a) et maintenues par la pression du plateau (a) sur les entretoises (e) sans que le support (d) sur lequel les planches (c) doivent être collées ne soit altéré par friction pendant la phase de cintrage. Dans la deuxième phase du pressage, les entretoises (e) sont enlevés, par enroulement par exemple, et le pressage permet alors de réaliser la jonction entre le support (d) et les planches (c). Pour faciliter l'extraction des entretoises (e), le plateau supérieur (a) peut être doté de zones rigides au dessus des zones où sont situés les entretoises (e) ainsi que de cavités (q) dans les autres zones de sorte que la variation de pression dans les cavités (q) permette, soit, par dépression (
- Ils optimisent la position des planches (c) en fonction de leurs défauts de rectitude et de calibrage au fur et à mesure du pressage.
- Ils facilitent l'extraction, puisque après collage, dés que la pression de la presse se relâche et que les plateaux (a)(b) sont séparés mécaniquement, le dégagement est facilité par la distance qui augmente entre les plots (f) et les planches (c) et ce dés le début de l'extraction.
- Ils limitent, par leur nombre leur hauteur et leur positionnement, les déformations des plateaux (a)(b) lorsque le pressage est réalisé alors que la presse n'est pas à sa charge totale (définie comme la totalité de la surface opérationnelle utilisée).
- They optimize the position of the boards (c) according to their straightness and calibration defects as and when the pressing.
- They facilitate the extraction, since after sticking, as soon as the pressure of the press is released and the trays (a) (b) are separated mechanically, the clearance is facilitated by the distance which increases between the pads (f) and the boards (c) and this dice the beginning of the extraction.
- They limit, by their number their height and their positioning, the deformations of the plates (a) (b) when the pressing is carried out while the press is not at its total load (defined as the totality of the operational surface used) .
La presse est donc conçue de telle manière qu'elle puisse être utilisée à une charge quelconque comprise entre presse vide et à pleine charge grâce à l'entretoisement réalisé entre les plots (f) sans dommage pour sa structure et tout en conservant une qualité de collage optimale réalisée avec une pression de pressage suffisante, déterminée en fonction des caractéristiques des produits à coller et des colles utilisées. L'extraction peut être facilitée (
Soit le plateau (b) porte des guides (k) (rails) dans lesquels se déplacent des chariots (h)(i) indépendants aussi nombreux qu'il y a de planches (c) à cintrer. Les chariots portent des parties (1)(m) permettant le positionnement et le maintien des planches (c). Les rails (k) sont disposés dans un axe tel que le mouvement des plots (1)(m) fixés sur les chariots (h)(i) qui coulissent sur les rails (k), alors que les planches (c) sont en position dans la presse, entraîne les planches (c) dans un mouvement parallèle aux plateaux (a)(b) de la presse et provoque un cintrage dans le plan des plateaux (a)(b) jusqu'à une forme préétablie. Les pièces de maintien et d'espacement (I)(m) sont de deux sortes (
- les unes (I) sont dotés de surfaces de contact avec les planches (c) aussi importantes et rugueuses que possible de telle sorte que lorsque la presse est en charge, les planches (c) soient maintenues dans le sens longitudinal les unes relativement aux autres par l'action de ces pièces(l).
- les autres pièces de maintien et d'espacement sont cylindriques ou tronconiques (m) permettant soit par glissement sur les planches (c) soit par déplacement des planches (c) autour de la pièce de maintien et d'espacement (m) un mouvement relatif des planches (c) entre elles pendant le cintrage sans modifier la distance entre les planches (c) du fait de la constance du diamètre de la pièce de maintien et d'espacement (m) et ce quelle que soit la courbure des planches (c).
- the ones (I) are provided with contact surfaces with the boards (c) which are as large and rough as possible so that when the press is in load, the boards (c) are held longitudinally relative to each other by the action of these pieces (l).
- the other holding and spacing pieces are cylindrical or frustoconical (m) allowing either sliding on the boards (c) or by moving the boards (c) around the holding and spacing piece (m) a relative movement boards (c) between them during bending without changing the distance between the boards (c) due to the constancy of the diameter of the holding part and spacing (m) and whatever the curvature of the boards (c) ).
Les pièces de maintien et d'espacement (I) (m) sont mises en mouvement dans les guides (k) par l'action de systèmes permettant une poussée maîtrisée comme, par exemple, des vérins (g) pneumatiques ou hydrauliques.The holding and spacing parts (I) (m) are set in motion in the guides (k) by the action of systems allowing a controlled thrust such as, for example, pneumatic or hydraulic cylinders (g).
Dans le cas ou des vérins (g) seraient utilisés, les tiges des vérins (n) auraient deux fonctions :
- La poussée pour obtenir le cintrage.
- Le maintien des plateaux (a)(b) de la presse afin d'éviter une déformation excessive des plateaux (a)(b) lors de la phase de pressage pour collage, dans les zones entre les plateaux (a)(b) de la presse qui ne sont pas en contact pour l'une avec les planches (c) et pour l'autre avec le support (d), la combinaison des deux constituant un entretoisement. Le pressage entre les deux plateaux (a) (b) peut être réalisé par tout moyen mécanique connu et maîtrisé (vis, vérin, came...). Il peut aussi être réalisé par la mise en dépression de la zone située entre les plateaux (a)(b). Dans ce cas une zone étanche peut être prévue soit en périphérie (r) d'un des plateaux soit sur les longueurs du plateau perpendiculairement à l'axe de déplacement des planches (c). Cette zone (r) permettant de maintenir par dépression les plateaux (a)(b) l'un par rapport à l'autre indépendamment de la pression au niveau de la zone sous laquelle les planches (c) sont mises en mouvement et cintrées. Dans le cas ou une déformation serait induite par les forces résultant du cintrage des planches (c) sur les plateaux (a) (b) et tendrait à écarter les plateaux (a) (b) et à dégager les planches (c) des guides (I) (m), des palpeurs peuvent être installés pour mesurer la déformation des plateaux (a) (b) de la presse. En fonction des indications obtenues de ces palpeurs, la zone entre les plateaux (a) (b) de la presse peut être mise en dépression ou surpression jusqu'à obtenir à nouveau une distance correcte des plateaux (a) (b) l'un relativement à l'autre sans que cette force ne nuise pour autant trop au mouvement des planches (c). La pression entre les plateaux (a) (b) peut être modifiée pour maintenir une distance optimale entre les plateaux (a) (b) pendant la phase de déplacement et de cintrage. Le mouvement des planches (c) entre les plateaux (a) (b) est limité par des butées (p) disposées de telle manière que la forme finale souhaitée est obtenue lorsque le déplacement des planches (c) par le mécanisme de poussée est tel que le système est arrêté dans son mouvement par l'ensemble des butées (p). Ces butées (p) peuvent être réalisées, entre autres méthodes, par des tiges (p) circulant dans les rails (k). Dans ce cas, les tiges (p) peuvent circuler poussées par les chariots (h)(i) et être limitées en mouvement par des butées fixes extérieures à la zone de pressage ou maintenues fixes avant le début du cintrage à une position déterminée en fonction de la forme finale souhaitée par un système de blocage (o). Dans les deux cas, lorsque les planches (c) sont mises à la forme finale souhaitée et pendant la phase de pressage pour collage, les tiges de butée (p) remplissent la même fonction que les tiges de vérin (n) en limitant la déformation des (c) et le support (d) ne font pas fonction d'entretoise.
- The push to get the bend.
- Maintaining trays (a) (b) of the press to avoid excessive deformation of trays (a) (b) during the pressing phase for gluing, in the areas between the plates (a) (b) of the press which are not in contact for one with the boards (c) and for the other with the support (d) ), the combination of the two constituting a bridging. The pressing between the two plates (a) (b) can be achieved by any known and controlled mechanical means (screw, cylinder, cam ...). It can also be achieved by depressurizing the area between the trays (a) (b). In this case a sealed zone may be provided either at the periphery (r) of one of the trays or on the lengths of the plate perpendicular to the axis of displacement of the boards (c). This zone (r) makes it possible to maintain the trays (a) (b) relative to each other independently of the pressure at the level of the zone under which the boards (c) are set in motion and bent. In the case where a deformation would be induced by the forces resulting from the bending of the boards (c) on the trays (a) (b) and tend to spread the trays (a) (b) and to clear the boards (c) of the guides (I) (m), probes can be installed to measure the deformation of the plates (a) (b) of the press. Depending on the indications obtained from these feelers, the area between the plates (a) (b) of the press can be put under vacuum or overpressure until again obtaining a correct distance from the plates (a) (b) one relatively to the other without this force does too much harm to the movement of the boards (c). The pressure between the trays (a) (b) can be varied to maintain an optimum distance between the trays (a) (b) during the moving and bending phase. The movement of the boards (c) between the plates (a) (b) is limited by stops (p) arranged in such a way that the desired final shape is obtained when the displacement of the boards (c) by the thrust mechanism is such that the system is stopped in its movement by all the stops (p). These stops (p) can be realized, among other methods, by rods (p) flowing in the rails (k). In this case, the rods (p) can circulate pushed by the carriages (h) (i) and be limited in motion by fixed abutments external to the pressing zone or kept fixed before the beginning of bending at a position determined according to of the desired final shape by a locking system (o). In both cases, when the boards (c) are put into the desired final shape and during the gluing stage, the stop rods (p) fulfill the same function as the cylinder rods (n) by limiting the deformation (c) and the support (d) do not act as spacers.
Une variante simplifiée de la presse permettant le cintrage peut être fabriquée en conservant exactement le même principe de fonctionnement mais en simplifiant sa réalisation. Dans ce cas, la presse ne comporte plus deux plateaux (a)(b) en vis-à-vis mais un seul plateau (a) sur lequel est positionné le support (d) sur lequel les planches (c) doivent être fixées par exemple par collage. Cette presse est munie d'un dispositif pour maintenir ou contraindre les planches à la position ou à la courbure souhaitée pendant le temps nécessaire à leur fixation sur le support (d). Le guidage des planches (c) parallèlement au support (d) sur lequel les planches (c) doivent être fixées, durant la phase de cintrage et le pressage des planches (c) sur le support (d) pour fixation après la phase de cintrage est réalisé par des rails disposées en vis à vis du plateau (a). Ils agissent indépendamment ou sont solidarisés entre eux et sont actionnés par un ou plusieurs dispositifs permettant de faire varier la distance entre les rails et le plateau (a) pour régler cette distance et assurer le pressage. Les dispositifs permettant d'actionner les rails peuvent être par exemple des vérins, des cames ou aussi un dispositif permettant la mise sous vide d'air de la zone comprise entre le plateau (a) et les rails. Ces rails sont en nombre suffisant pour permettre une pression homogène sur les planches (c) afin d'en permettre la fixation correcte sur le support. Ces rails seront généralement disposés dans un axe transversal ou radial par rapport à l'axe longitudinal des planches (c) mais peuvent si nécessaire être disposés dans tout axe parallèle au plateau (a). Les rails (k) peuvent ou non porter des chariots (h) (i) tels que décrits précédemment pour assurer l'espacement des planches. Si les rails ne portent pas de chariots munis de plots d'espacement, l'espacement constant pendant toute la phase de cintrage peut être obtenu en disposant des cales calibrées entre les planches. Ces cales d'espacement pourront ensuite être retirées une fois la fixation des planches sur le support réalisée. Le cintrage peut être réalisé par tout moyen permettant de générer un effort dans le plan de cintrage par exemple un ou des vérins pneumatiques, hydrauliques ou à vis. Les vérins peuvent être portés par les rails de pressage.A simplified variant of the press for bending can be manufactured keeping exactly the same principle of operation but simplifying its implementation. In this case, the press no longer has two trays (a) (b) facing each other but only one plate (a) on which is positioned the support (d) on which the boards (c) must be fixed by example by gluing. This press is provided with a device for maintaining or constraining the boards to the desired position or curvature for the time necessary for their fixing on the support (d). The guiding of the boards (c) parallel to the support (d) on which the boards (c) must be fixed, during the bending phase and the pressing of the boards (c) on the support (d) for fixing after the bending phase is made by rails arranged opposite the plate (a). They act independently or are interconnected and are actuated by one or more devices for varying the distance between the rails and the plate (a) to adjust this distance and ensure the pressing. The devices for actuating the rails may be for example cylinders, cams or also a device for evacuation of air from the area between the plate (a) and the rails. These rails are in sufficient number to allow a uniform pressure on the boards (c) to allow proper fixing on the support. These rails will generally be arranged in a transverse or radial axis relative to the longitudinal axis of the boards (c) but may if necessary be arranged in any axis parallel to the plate (a). The rails (k) may or may not carry carriages (h) (i) as previously described to ensure the spacing of the boards. If the rails do not carry carriages provided with spacing studs, the constant spacing during the entire bending phase can be obtained by arranging wedges calibrated between the boards. These spacer blocks can then be removed once the fixing of the boards on the support made. The bending can be achieved by any means for generating a force in the bending plane for example one or pneumatic cylinders, hydraulic or screw. The cylinders can be carried by the pressing rails.
Dans cet appareil, le plateau (a) et la partie de la presse supportant les rails permettant le guidage et le pressage peuvent être rendus solidaires et maintenus pendant la phase de cintrage des planches (c) par la mise en dépression d'une zone (r), soit en périphérie (r) du plateau (a), soit sur les longueurs du plateau (a) perpendiculairement à l'axe de déplacement des planches. De la sorte les rails permettant le guidage et le pressage des planches peuvent être maintenus en vis-à-vis du plateau (a). La force générée par la dépression est suffisante pour autoriser la mise en oeuvre dans de bonnes conditions des mécanismes permettant le cintrage et le pressage.In this apparatus, the plate (a) and the portion of the press supporting the rails for guiding and pressing can be made integral and maintained during the bending phase of the boards (c) by the depression of a zone ( r), either at the periphery (r) of the plate (a), or at the lengths of the plate (a) perpendicular to the axis of displacement of the boards. In this way the rails allowing the guiding and pressing of the boards can be maintained in relation to the plate (a). The force generated by the depression is sufficient to allow the implementation in good conditions mechanisms for bending and pressing.
