Abstract

The invention relates to a method for horizontally using the diagonal 1-2 of a polygonal working table 3 which can be inclined and adjusted for height by virtue of two journals 8, with respect to the ground 4-5 in order to make use of gravity on a skewed work surface. Under this effect, and according to the example set forth, the components 11-12-16 and 17 are stopped before they fall in the desired position by pegs 9-10-13 and 14 judiciously embedded in the working table 3. This method applies to the manufacture of handling pallets, to that of the panels making up containers (bottoms, lids, walls) and, in general, to any activity consisting in combining various elements made from wood or similar materials, in an accurate way before assembly.

Description

DESCRIPTION
Le procédé de l'invention concerne - La fabrication de palettes de manutention (à 2 ou 4 entrées ; avec
plancher supérieur ou inférieur, débordant ou pas ; à simple ou double
face) - La fabrication de panneaux (fonds, côtés, couvercles) constituant les
conteneurs de manutention - D'une façon générale, toute activité devant associer des éléments divers,
en bois ou en matières similaires, de manière précise avant lê=r
assemblage - La production de petite et moyenne séries.DESCRIPTION
The method of the invention relates to - The manufacture of handling pallets (with 2 or 4 inlets; with
upper or lower floor, overflowing or not; single or double
front) - The manufacture of panels (bottoms, sides, covers) constituting the
handling containers - Generally, any activity that must combine various elements,
of wood or the like, precisely before lê = r
assembly - Production of small and medium series.

Les brevets déposés antérieurement n'utilisent, au mieux, qu'un seul plan incliné. Cette situation implique le maintien par divers artifices (ressorts, butées élastiques, goulottes, vérins,...) des éléments constitutifs (dés, chevrons, planches, ...). Pour dégager l'oeuvre, l'opérateur dispose d'une manette ou d'une pédale agissant sur un système de dégagement. Le changement de production est une opération longue et délicate qui fait appel à un personnel compétent. De plus l'entretien doit en être régulier avec comme conséquences, dues à ces techniques, un coût important qui se repporte sur le prix de revient final.Patents previously filed use, at best, only one inclined plane. This situation involves the maintenance by various devices (springs, elastic stops, chutes, jacks, ...) of the constituent elements (dice, rafters, boards, ...). To release the work, the operator has a joystick or a pedal acting on a release system. The change of production is a long and delicate operation which requires competent personnel. In addition, maintenance must be regular with the consequences, due to these techniques, of a significant cost which is carried over to the final cost price.

Autres inconvénients des diverses solutions en présence viennent du fait qu'un élément trop long ou trop large ne rentre pas à sa place, et que si il est trop court ou trop étroit il nage dans son logement, entraînant donc des rebuts et des pertes de temps.Other drawbacks of the various solutions present come from the fact that an element that is too long or too wide does not fit in its place, and that if it is too short or too narrow it swims in its housing, thus causing waste and loss of time.

Les progrès apportés par le présent procédé objet de l'invention consistent en - Suppression des réglages lors des changements de production, des visites
périodiques d'entretien, des pièces de rechange d'où allègement de la
charge du personnel et diminution des immobilisations - Grande facilité de dégagement du produit fini ou semi-fini due à la
position particulière du plan de travail et à l'absence de tout maintien; - Investissement minime grâce à la simplicité du principe et à la
possibilité d'effectuer une production à partir du même poste de travail,
lequel est adaptable à la morphologie de l'opérateur (taille, longueur des
membres, gaucher ou droitier).The progress made by the present process which is the subject of the invention consists of - Deleting settings during production changes, visits
periodic maintenance, spare parts, hence reducing the
staff costs and reduction in fixed assets - Great ease of release of the finished or semi-finished product due to the
particular position of the work plan and the absence of any maintenance; - Minimal investment thanks to the simplicity of the principle and the
possibility of producing from the same workstation,
which is adaptable to the operator's morphology (size, length of
members, left or right handed).

La particularité essentielle de l'invention réside dans le fait que la diagonale horizontale (1-2) du plan de travail (3) de forme hexagonale ou rectangulaire pivote, s'incline et se règle en hauteur de façon combinée jouant ainsi avec la gravité sur un plan gauche.The essential characteristic of the invention lies in the fact that the horizontal diagonal (1-2) of the work surface (3) of hexagonal or rectangular shape pivots, tilts and adjusts in height in a combined manner thus playing with gravity on a left plane.

Dans ces conditions, 2 pions (9) suffisent à situer précisément un élément cubique, tel un dé (11), et 3 pions (10)(13)(14) sont nécessaires pour des éléments fins et longs, tels des planches (12)(16)(17).La hauteur de ces pions est toujours inférieure à la hauteur des élémer s à retenir. Leur implantation associe autant de fonctions possibles afin d'en limiter le nombre au strict minimum. Sur les figures 4 et 7, de l'exemple choisi et défini ci-après, la totalité des pions utiles est représentée ; par contre sur les figures 4, 5, 8, 9 et 10 seuls ceux actifs dans la phase de travail concernée sont dessinés.Under these conditions, 2 pawns (9) are sufficient to precisely locate a cubic element, such as a die (11), and 3 pawns (10) (13) (14) are necessary for thin and long elements, such as planks (12 ) (16) (17) .The height of these pawns is always less than the height of the elements to be retained. Their establishment combines as many possible functions in order to limit the number to the strict minimum. In FIGS. 4 and 7, of the example chosen and defined below, all of the useful pins are shown; on the other hand in FIGS. 4, 5, 8, 9 and 10 only those active in the work phase concerned are drawn.

L'invention étant un procédé de fabrication, l'exemple décrit à travers les figures jointes est un cas particulier simple et nullement exhaustif d'une palette constituée de - 9 dés intercallaires (11) - 3 planches longitudinales inférieures (12) - 3 planches transversales supérieures (16) - 5 planches longitudinales supérieures débordantes (17).The invention being a manufacturing process, the example described through the attached figures is a simple and in no way exhaustive particular case of a pallet consisting of - 9 interlayer dice (11) - 3 lower longitudinal boards (12) - 3 boards transverse upper (16) - 5 overhanging upper longitudinal boards (17).

Dans les figures annexées, se trouve en - 1, Poste de travail, vu de face - 2, Poste de travail, vu de gauche, en position 3A - 3, Poste de travail, vu de droite, en position 3B - 4, Table, vue de face, en position 3A - 5, 6, Phases de constitution de fonds de palettes - 7, Table, vue de face, en position 3B - 8, 9, 10, Phases de finitions de la palette - 11, Table rectangulaire, vue de face - 12, Table hexagonale disposée pour gaucher, vue de face - 13, Table rectangulaire disposer pour gaucher, vue de face.In the appended figures, is in - 1, Workstation, seen from the front - 2, Workstation, seen from the left, in position 3A - 3, Workstation, seen from the right, in position 3B - 4, Table , front view, in position 3A - 5, 6, Phases of creation of pallet bottoms - 7, Table, front view, in position 3B - 8, 9, 10, Phases of finishing of the pallet - 11, Rectangular table , front view - 12, Hexagonal table arranged for left-handed, front view - 13, Rectangular table arranged for left-handed, front view.

Ne sont pas représentés sur les figures les systèmes de blocage en rotation et de réglage en hauteur de la table (3) ; de même que le sous ensemble constituant le support. De plus sur les figures 11, 12 et 13 aucun repère n'est pratiquement porté afin de faciliter la compréhension du présent descriptif.Are not shown in the figures the rotation blocking and height adjustment systems of the table (3); as well as the sub-assembly constituting the support. In addition, in FIGS. 11, 12 and 13, no benchmark is practically worn in order to facilitate understanding of this description.

Pour réaliser l'exemple précité, l'opérateur choisit son angle de travail en inclinant la table (3) par rapport à l'axe (1-2), le pivotement s'effectue grâce aux 2 tourbillons (8) solidaires de la table (3), puis il bloque celle-ci une fois l'angle souhaité atteint. Enfin il règle la hauteur de son travail par rapport au sol (4-5) en faisant varier le niveau des 2 tourbillons (8) le long de l'axe vertical (6-7).To carry out the above example, the operator chooses his working angle by tilting the table (3) relative to the axis (1-2), the pivoting takes place thanks to the 2 vortices (8) integral with the table (3), then it blocks it once the desired angle is reached. Finally he adjusts the height of his work in relation to the ground (4-5) by varying the level of the 2 vortices (8) along the vertical axis (6-7).

Ainsi l'opérateur peut maintenant placer sur la face (3A) de la table (3) les 18 dés (11) puis les 6 planches (12). Les 18 pions courts (9) et les 18 pions plus longs (10) accueilleront ces éléments suivant les figures 5 et;6. Thus the operator can now place on the face (3A) of the table (3) the 18 dice (11) then the 6 boards (12). The 18 short pawns (9) and the 18 longer pawns (10) will accommodate these elements according to Figures 5 and; 6.

Arrivé au stade de la figure 6, l'assemblage, par des moyens traditionnels, des planches (12) sur les dés (11) est effectué. Sont obtenus 6 fonds (11+12), soit l'ébauche de 2 palettes.Arrived at the stage of figure 6, the assembly, by traditional means, of the boards (12) on the dice (11) is carried out. Are obtained 6 funds (11 + 12), the draft of 2 pallets.

La série de fonds terminée, la table (3) est retournée, l'inclinaison retrouvée et bloquée à nouveau en position (3B).When the series of funds is finished, the table (3) is turned over, the tilt found and locked again in position (3B).

L'opérateur poursuit en installant 3 fonds (11+12), dés (11) en l'air, puis les 3 planches (16) et les 5 planches (17). Ces éléments sont arrêtés par 15 pions longs (13) et 4 pions moins hauts (14). Au droit des croisements de planches (16 et 17) où aucun dé (11) n'est présent, sont implantés sur la face (3B) 6 réhausses de rivetage (15) de hauteur égale à celle des fonds (11+12).The operator continues by installing 3 funds (11 + 12), dice (11) in the air, then the 3 boards (16) and the 5 boards (17). These elements are stopped by 15 long pawns (13) and 4 less high pawns (14). In line with the crossings of planks (16 and 17) where no die (11) is present, 6 riveting risers (15) of height equal to that of the bottoms (11 + 12) are located on the face (3B).

Dés le dernier élément posé, l'assemblage final est entrepris pour aboutir à l'achèvement du produit recherché.As soon as the last element is installed, the final assembly is undertaken to lead to the completion of the desired product.

En ce qui concerne la petite série, il est évident qu'une seule table (3) suffit en l'utilisant sur ses 2 faces (3A et 3B) avec un seul opérateur.With regard to the small series, it is obvious that a single table (3) is sufficient by using it on its 2 faces (3A and 3B) with a single operator.

Pour une série plus importante, 2 tables (3) complètes et 2 opérateurs sont employés avec la possibilité de fabriquer 2 produits différents (l'un sur les 2 faces (3A) et l'autre sur les 2 faces (3B), par exemple). Si par contre un seul produit est souhaité à cette cadence la table peut être réduite à un rectangle (Fig.11) utilisé pareillement à un hexagone.For a larger series, 2 complete tables (3) and 2 operators are used with the possibility of manufacturing 2 different products (one on the 2 sides (3A) and the other on the 2 sides (3B), for example ). If, on the other hand, only one product is desired at this rate, the table can be reduced to a rectangle (Fig. 11) used similarly to a hexagon.

Dans le cas d'opérateur gaucher, le poste est adaptable en choisissant une implantation inverse des pions sur l'hexagone (3B') de la figure 12 ou en utilisant la deuxième diagonale du rectangle selon la figure 13.In the case of left-handed operator, the station is adaptable by choosing a reverse implantation of the pins on the hexagon (3B ') of figure 12 or by using the second diagonal of the rectangle according to figure 13.

En cas de productions multiples, un changement de programme se réduit à ne remplacer que la table (3) ; le reste (support de l'ensemble, systèmes de réglages et de blocage, etc) étant réutilisé aux mêmes fins qu'auparavant. In the case of multiple productions, a change of program is reduced to replacing only the table (3); the rest (support for the assembly, adjustment and blocking systems, etc.) being reused for the same purposes as before.
