Description
APPAREIL POUR LE VISSAGE, SEMI-AUTOMATIQUE, D'ELEMENTS DE FIXATION.APPARATUS FOR THE SEMI-AUTOMATIC CUTTING OF FIXING ELEMENTS
La présente invention concerne un appareil pour le vissage, semi-automatique, d'éléments de fixation réalisés en au moins deux parties préassemblées dont l'une est constituée par une pièce d'appui et/ou de fixation, tandis que l'autre comporte une vis préengagée dans un orifice de la première partie.The present invention relates to an apparatus for the semi-automatic screwing of fastening elements made of at least two preassembled parts, one of which is constituted by a support and / or fixing piece, while the other comprises a screw preengaged in a hole of the first part.
Elle s'applique notamment, mais non exclusivement, à la fixation de panneaux isolants sur une structure support au moyen d'éléments de fixation comprenant un fut tabulaire de diamètre intérieur au moins égal à celui de la tête de la vis utilisée, dont une extrémité est munie d'un collet de retenue par exemple circulaire ou rectangulaire qui s'étend sensiblement radialement et dont l'autre extrémité, habituellement de forme pointue, présente un rétrécissement d'alésage de diamètre inférieur à celui de la tête de la vis.It applies in particular, but not exclusively, to the fixing of insulating panels on a support structure by means of fasteners comprising a tabular futon of internal diameter at least equal to that of the head of the screw used, one end of which is provided with a retaining collar, for example circular or rectangular, which extends substantially radially and whose other end, usually of pointed shape, has a bore narrowing of diameter smaller than that of the head of the screw.
On sait que pour faciliter une telle fixation et pour réduire le temps de son exécution, on utilise de plus en plus souvent des appareils de vissage comprenant un magasin dans lequel est stockée une pluralité d'éléments de fixation de ce type, un distributeur permettant d'amener un à un les éléments de fixation dans une zone de vissage et des moyens de vissage aptes à effectuer un vissage de la vis.It is known that to facilitate such fixing and to reduce the time of its execution, it is more and more often used screwing devices comprising a magazine in which is stored a plurality of fasteners of this type, a dispenser for bring one by one the fastening elements in a screwing zone and screwing means capable of screwing the screw.
Ainsi, on a déjà proposé dans le brevet FR No 99 09830 déposé au nom de RLB, un appareil permettant le vissage d'éléments de fixation sur lesquels sont prévissées des vis de tailles différentes, le magasin de cet appareil étant alimenté par des éléments de fixation éventuellement portés par une bande. Une fois les éléments de fixation engagés dans le magasin, cette bande est extraite en effectuant une traction axée perpendiculairement aux éléments de guidage.Thus, it has already been proposed in patent FR No. 99 09830 filed in the name of RLB, an apparatus for screwing fasteners on which are Screws of different sizes are provided, the magazine of this apparatus being powered by fasteners possibly carried by a band. Once the fasteners engaged in the magazine, this band is extracted by making a traction oriented perpendicularly to the guide elements.
D'une façon plus précise, cet appareil comprend un magasin constitué par un dispositif de guidage comportant deux guides profilés parallèles présentant deux concavités respectives en forme de gorge situées en regard l'une de l'autre de manière à délimiter un espace sensiblement cruciforme comprenant deux branches fermées dans lesquelles les éléments de fixation peuvent s'engager et être guidés par les bordures latérales des collets et deux branches ouvertes dans lesquelles les vis préengagées dans les éléments de fixation et/ou les fûts peuvent passer.More precisely, this apparatus comprises a magazine constituted by a guiding device comprising two parallel profiled guides having two respective concavities in the form of grooves facing each other so as to delimit a substantially cruciform space comprising two closed branches in which the fasteners can engage and be guided by the side edges of the collars and two open branches in which the screws pre-engaged in the fasteners and / or drums can pass.
Dans cet appareil, le distributeur servant à délivrer un à un les éléments de fixation contenus dans le magasin comprend un pignon épaulé monté rotatif au voisinage du dispositif de guidage selon un axe orienté parallèlement aux vis et/ou aux fûts des éléments de fixation contenus dans le magasin. Ce pignon épaulé comprend une cavité axialement traversante dont le fond présente une forme hémicylindrique coaxiale et qui débouche du côté opposé au fond, au niveau de la périphérie du pignon. Cette cavité est dimensionnée de manière à ce que la vis et/ou le fût d'un élément de fixation puisse s'y engager. Ce pignon est entraîné en rotation par une crémaillère solidaire du mouvement de translation de la visseuse de manière à prendre :In this apparatus, the dispenser serving to deliver one by one the fasteners contained in the magazine comprises a stepped pinion rotatably mounted in the vicinity of the guide device along an axis oriented parallel to the screws and / or drums of the fasteners contained in the shop. This stepped pinion comprises an axially through cavity whose bottom has a coaxial hemicylindrical shape and which opens on the opposite side to the bottom, at the periphery of the pinion. This cavity is dimensioned so that the screw and / or the barrel of a fastener can engage. This pinion is rotated by a rack integral with the translational movement of the screwdriver so as to take:
- une position dans laquelle la cavité est orientée vers le magasin de manière à pouvoir recevoir la vis et/ou le fût d'un élément de fixation contenu dans le magasin, - une position à 180° de la précédente, dans laquelle la cavité orientée à l'opposé du magasin permet l'extraction dudit élément de fixation. Cette solution qui permet d'obtenir d'excellents résultats, présente néanmoins les inconvénients :a position in which the cavity is oriented towards the magazine so as to be able to receive the screw and / or the barrel of a fixing element contained in the magazine, a position 180 ° from the previous one, in which the cavity oriented opposite the magazine allows extraction of said fastener. This solution, which makes it possible to obtain excellent results, nevertheless has the disadvantages:
- de ne pouvoir utiliser qu'un seul type d'éléments de fixation présentant un collet de dimensions et de forme déterminées, - de faire intervenir un mécanisme relativement complexe et donc coûteux.- Can only use a single type of fasteners having a neck of specified size and shape, - to involve a relatively complex mechanism and therefore expensive.
L'invention a donc plus particulièrement pour but de supprimer ces inconvénients.The object of the invention is therefore more particularly to eliminate these disadvantages.
A cet effet, elle propose un appareil présentant une structure générale similaire à celle précédemment décrite, mais dans lequel :For this purpose, it proposes an apparatus having a general structure similar to that previously described, but in which:
« Le magasin comprend deux guides latéraux parallèles écartés l'un de l'autre d'une distance légèrement supérieure au diamètre d'un fût mais inférieure à la largeur ou au diamètre d'un collet et un guide central qui s'étend en regard des guides latéraux dans un plan parallèle au plan desdits guides latéraux, à une distance de ce plan légèrement supérieure à l'épaisseur maximum du collet."The magazine has two parallel lateral guides spaced from each other by a distance slightly greater than the diameter of a drum but smaller than the width or diameter of a collar and a central guide which extends opposite lateral guides in a plane parallel to the plane of said lateral guides, at a distance from this plane slightly greater than the maximum thickness of the collar.
• Les deux guides latéraux sont prolongés au-delà du distributeur par une portion recourbée destinée à amener les éléments de fixation au droit d'un puits de vissage dans l'axe duquel est disposée une visseuse mobile parallèlement audit axe.• The two lateral guides are extended beyond the distributor by a curved portion for bringing the fasteners to the right of a screw well in the axis of which is disposed a movable screwdriver parallel to said axis.
• Le distributeur comprend un tiroir mobile parallèlement au plan des guides latéraux selon un axe de déplacement perpendiculaire à ces derniers, ce tiroir comprenant, dans sa partie supérieure, une fourche apte à chevaucher les deux guides latéraux et, dans sa partie inférieure, une pièce d'appui située à l'opposé de la fourche, l'écart de hauteur entre la fourche et la pièce d'appui étant au moins égal à la somme du rayon (ou de la demi-largeur) du collet et du rayon de la surface extérieure du tut. Ce distributeur est actionné de manière à ce que le tiroir puisse occuper : - une première position dans laquelle la fourche chevauche les deux guides latéraux de manière à retenir par son fût l'élément de fixation situé en bas de la pile contenue dans le magasin, et la pièce d'appui se trouve latéralement décalée par rapport à l'intervalle des deux guides latéraux de manière à libérer le passage de l'élément de fixation qui se trouve compris entre la fourche et l'élément de fixation, - une deuxième position dans laquelle la fourche se trouve latéralement décalée vis-à-vis des deux guides pour laisser le passage de l'élément de fixation situé en bas de la pile tandis que la pièce d'appui est disposée en regard de l'intervalle compris entre les deux guides de manière à retenir par son fût cet élément de fixation.• The dispenser comprises a movable drawer parallel to the plane of the lateral guides along an axis of displacement perpendicular to the latter, this drawer comprising, in its upper part, a fork adapted to overlap the two lateral guides and, in its lower part, a piece on the opposite side of the fork, the difference in height between the fork and the workpiece of support being at least equal to the sum of the radius (or half-width) of the collar and the radius of the outer surface of the tut. This dispenser is actuated so that the drawer can occupy: a first position in which the fork overlaps the two lateral guides so as to retain by its barrel the fixing element located at the bottom of the stack contained in the store, and the support piece is laterally offset with respect to the interval of the two lateral guides so as to release the passage of the fastening element which is between the fork and the fixing element, - a second position wherein the fork is laterally offset with respect to both guides to allow the passage of the fastener located at the bottom of the stack while the support piece is disposed opposite the gap between the two guides so as to retain by its barrel this fastener.
Avantageusement, les déplacements du tiroir sont commandés par les déplacements de la visseuse/dévisseuse grâce à un dispositif de conversion translation verticale/translation horizontale.Advantageously, the movements of the drawer are controlled by the movements of the screwdriver / unscrewing through a conversion device vertical translation / horizontal translation.
Un élément de guidage supplémentaire pourra être associé aux guides latéraux en aval du distributeur pour maintenir les éléments de fixation dont les collets présentent des formes rectangulaires orientées parallèlement à l'axe des guides latéraux. Dans ce cas, un élément de butée pourra être prévu au niveau du distributeur de manière à ce que les collets polygonaux ou oblongs se disposent selon cette orientation dans l'intervalle entre la fourche et la pièce d'appui du tiroir.An additional guide member may be associated with the lateral guides downstream of the distributor to hold the fasteners whose collars have rectangular shapes oriented parallel to the axis of the lateral guides. In this case, a stop element may be provided at the distributor so that the polygonal or oblong collars are arranged in this direction in the gap between the fork and the support part of the drawer.
De préférence, le puits de vissage présente une hauteur supérieure à la hauteur maximale que peut avoir un élément de fixation, depuis le collet jusqu'à la pointe de la vis. Dans sa partie supérieure, le puits comprend des moyens de rétention escamotables destinés à retenir les collets des éléments de fixation jusqu'à ce que la tige de vissage de la visseuse/dévisseuse s'engage dans le fût de l'élément de fixation qui se trouve retenu et vienne en prise sur la tête de la vis, ces moyens de rétention s'escamotant ensuite sous l'effet de la pression exercée vers le bas par la tige de vissage sur l'élément de fixation.Preferably, the screw well has a height greater than the maximum height that can have a fastener, from the collar to the tip of the screw. In its upper part, the well comprises retractable retention means for retaining the collars of the fasteners until the screwing rod of the screwdriver / stripper engages in the barrel of the fastener which is is retained and comes into engagement with the head of the screw, these retention means then retracting under the effect of the pressure exerted downwards by the screw rod on the fastener.
A l'intérieur du puits de vissage, les collets des éléments de fixation sont guidés par deux plaques sensiblement verticales de profil légèrement concave disposées l'une en regard de l'autre, l'une de ces deux plaques étant articulée dans sa partie inférieure et étant sollicitée par des moyens élastiques en direction de l'autre plaque vers une position dans laquelle ces deux plaques sont écartées l'une de l'autre d'une distance minimum prédéterminée.Inside the screw well, the collars of the fasteners are guided by two substantially vertical plates of slightly concave profile arranged one facing the other, one of these two plates being hinged in its lower part. and being biased by elastic means towards the other plate to a position in which these two plates are spaced from each other by a predetermined minimum distance.
Grâce à ces dispositions, l'appareil selon l'invention présente une structure relativement simple, peu coûteuse et permet néanmoins un fonctionnement particulièrement fiable pour des éléments de fixation pouvant présenter des formes et des dimensions différentes.Thanks to these arrangements, the apparatus according to the invention has a relatively simple structure, inexpensive and nevertheless allows a particularly reliable operation for fasteners that can have different shapes and dimensions.

Comme précédemment mentionnée, le dispositif selon l'invention s'applique à la pose d'un élément de fixation 1 comprenant un fût tabulaire 2 dont une extrémité est munie d'un collet de retenue 3 tandis que l'autre extrémité, de forme sensiblement tronconique, présente un rétrécissement d'alésage 4. Usuellement, cet élément est réalisé en matière plastique moulée de manière à éviter tout pont de conduction thermique.As previously mentioned, the device according to the invention applies to the installation of a fastening element 1 comprising a tubular shaft 2, one end of which is provided with a retaining collar 3 while the other end, of substantially This frustoconical element has a boring narrowing 4. Usually, this element is made of plastic molded so as to avoid any thermal conduction bridge.
Bien entendu, l'invention ne se limite pas à la matière plastique, d'autres matériaux pouvant également être utilisés pour éviter la création de ponts theraiiques. L'élément 1 coopère avec une vis 5 qui s'engage dans l'alésage 6 du fut 2 et passe au travers du rétrécissement d'alésage 4.Of course, the invention is not limited to plastic, other materials can also be used to avoid the creation of bridges theraiiques. The element 1 cooperates with a screw 5 which engages in the bore 6 of the barrel 2 and passes through the bore narrowing 4.
La tête 7 de la vis 5 présente un diamètre sensiblement égal au diamètre de l'alésage 6. De ce fait, elle se trouve guidée par cet alésage. En fin de vissage, cette tête 7 vient en butée contre le palier effectuant la transition entre l'alésage 6 et le rétrécissement d'alésage 4.The head 7 of the screw 5 has a diameter substantially equal to the diameter of the bore 6. As a result, it is guided by this bore. At the end of screwing, this head 7 abuts against the bearing making the transition between the bore 6 and the bore narrowing 4.
Pour assurer l'imperdabilité de la vis 5 ainsi que la protection de l'opérateur, l'alésage 6 du fût 2 est muni d'une ou plusieurs protubérances 8 que la tête de la vis doit franchir, à force, en provoquant une légère déformation élastique du fût 2. Cette opération peut s'effectuer en usine lors du prémontage de la vis, à l'aide d'un outil spécial. Elle peut également s'effectuer in situ, par l'opérateur.To ensure the imperceptibility of the screw 5 and the protection of the operator, the bore 6 of the barrel 2 is provided with one or more protuberances 8 that the head of the screw must cross, forcibly, causing a slight elastic deformation of the drum 2. This operation can be carried out at the factory during the pre-assembly of the screw, using a special tool. It can also be done in situ, by the operator.
A cet effet, le rétrécissement d'alésage 4 est lui-même muni d'une ou plusieurs protubérances axiales destinées à permettre l'obtention d'un effet de vissage de la vis 5. Grâce à cette disposition, le passage en force de la vis 5 par les protubérances 8 du fût 2 peut être obtenu grâce à cet effet de vissage.For this purpose, the bore narrowing 4 is itself provided with one or more axial protuberances intended to allow to obtain a screwing effect of the screw 5. Thanks to this arrangement, the passage in force of the screw 5 by the protuberances 8 of the barrel 2 can be obtained thanks to this screwing effect.
Les formes et les dimensions des éléments de fixation utilisables par l'appareil selon l'invention peuvent être très différentes et correspondre aux gammes d'éléments de fixation de ce genre actuellement disponibles sur le marché.The shapes and dimensions of the fasteners usable by the apparatus according to the invention can be very different and correspond to the ranges of fasteners of this kind currently available on the market.
En particulier, les collets de ces éléments de fixation peuvent par exemple être circulaires (figure 2), oblongs, polygonaux (figure 3) ou présenter une combinaison de ces formes. Les fûts 2 et les vis 5 peuvent présenter des longueurs différentes de manière à ce que, pour une application donnée, l'utilisateur puisse associer un fût et une vis présentant des longueurs les mieux appropriées pour cette application.In particular, the collars of these fasteners may for example be circular (Figure 2), oblong, polygonal (Figure 3) or have a combination of these forms. The drums 2 and the screws 5 may have different lengths so that, for a given application, the user can associate a drum and a screw having the most appropriate lengths for this application.
Tel qu'illustré sur les figures 4 et 5, l'appareil de vissage comprend un châssis 11 comprenant une embase 12 renforcée par des traverses 15, 16. Cette embase 12 est montée sur deux paires de roues 17, 17' sensiblement coaxiales à la traverse d'extrémité 16.As illustrated in FIGS. 4 and 5, the screwing apparatus comprises a frame 11 comprising a base 12 reinforced by crosspieces 15, 16. This base 12 is mounted on two pairs of wheels 17, 17 'substantially coaxial with the end cross member 16.
Cette embase 12 porte deux colonnes parallèles 18, 19 sensiblement verticales sur lesquelles coulisse un chariot 20 portant une visseuse/dévisseuse 21, ce chariot 20 étant muni de deux poignées 22, 23 servant à assurer les déplacements par roulage de l'appareil et à imprimer un mouvement de translation vertical à la visseuse 21. Le chariot est par ailleurs soumis à une force de rappel vers le haut exercée par des ressorts hélicoïdaux logés dans les colonnes 18, 19.This base 12 carries two parallel columns 18, 19 substantially vertical on which slides a carriage 20 carrying a screwdriver / unscrewer 21, this carriage 20 being provided with two handles 22, 23 used to ensure the movement of the rolling device and to print vertical translation movement to the screwdriver 21. The carriage is also subject to an upward biasing force exerted by helical springs housed in the columns 18, 19.
Par ailleurs, ces deux colonnes 18, 19 sont reliées entre elles par trois entretoises, à savoir :Moreover, these two columns 18, 19 are interconnected by three spacers, namely:
- une entretoise supérieure 24 sensiblement en forme de C qui relie leurs extrémités supérieures,a substantially C-shaped upper spacer 24 which connects their upper ends,
- une entretoise inférieure 25, de forme droite, munie de trois évidements verticaux, à savoir (figure 9) : deux perçages extérieurs 26, 27 dans lesquels passent et viennent se fixer les colonnes 18, 19 et un évidement central 28, en forme de losange à angles incurvés qui est ouvert au niveau de l'un de ses sommets grâce à une fente 29 axée perpendiculairement au plan des deux colonnes 18, 19, cet évidement central 28 présentant une section appropriée pour laisser le passage, dans un puits de vissage PV, de collets 3 de tous les éléments de fixation 1 que l'on peut envisager de fixer grâce à l'appareil (la fente 29 permettant le passage des fûts 2 et l'extrémité des vis), et- a lower spacer 25, of straight shape, provided with three vertical recesses, namely (Figure 9): two external holes 26, 27 in which pass and are fixed the columns 18, 19 and a central recess 28, in the form of diamond with curved angles which is open at one of its vertices thanks to a slot 29 oriented perpendicularly to the plane of the two columns 18, 19, this central recess 28 having a section suitable for allowing the passage, in a screwing well PV, collars 3 of all fasteners 1 that can be considered to fix thanks to the device (the slot 29 allowing the passage of drums 2 and the end of the screws), and
- une entretoise intermédiaire 30 présentant, dans le plan des colonnes 18, 19, une forme en Ω de concavité orientée vers le bas, cette entretoise comprenant, au niveau de ses ailes latérales, deux perçages latéraux respectifs dans lesquels passent et viennent se fixer les colonnes 18, 19 et un perçage central destiné à assurer le passage de la tige de vissage 31 entraînée par la visseuse/dévisseuse 21.an intermediate spacer 30 having, in the plane of the columns 18, 19, a downwardly concave shape of Ω, this spacer comprising, at its lateral wings, two respective lateral holes in which the columns 18, 19 and a central bore for ensuring the passage of the screwing rod 31 driven by the screwdriver 21.
Cette entretoise intermédiaire coopère avec une butée réglable consistant en deux manchons tubulaires se vissant l'un dans l'autre, par lesquels passe la colonne 19. L'un de ces manchons est solidarisé à la colonne 19 en un emplacement réglable.This intermediate spacer cooperates with an adjustable stop consisting of two tubular sleeves screwing into each other, through which the column 19. One of these sleeves is secured to the column 19 in an adjustable position.
Les entretoises supérieure et intermédiaire sont reliées entre elles par une tige de guidage verticale 32 sur laquelle coulisse un tube d'entraînement 33.The upper and intermediate spacers are interconnected by a vertical guide rod 32 on which slides a drive tube 33.
Les entretoises supérieure 24 et inférieure 25 supportent un magasin M d'éléments de fixation comprenant deux guides latéraux parallèles cylindriques 34, 35 écartés l'un de l'autre d'une distance légèrement supérieure au diamètre d'un fût 2 mais inférieure à la largeur (ou au diamètre) maximale d'un collet 3 et un guide central constitué par une bande 36 qui s'étend en regard des guides latéraux 34, 35 dans un plan parallèle au plan des guides, à une distance de ce plan légèrement supérieure à l'épaisseur maximum du collet 3.The upper and lower spacers 25 support a fastener magazine M comprising two parallel cylindrical lateral guides 34, spaced from each other by a distance slightly greater than the diameter of a drum 2 but smaller than the maximum width (or diameter) of a collar 3 and a central guide constituted by a strip 36 which extends opposite the lateral guides 34, 35 in a plane parallel to the plane of the guides, at a distance from this plane slightly greater at the maximum thickness of the collar 3.
Dans la partie qui constitue le magasin (entre l'entretoise supérieure et l'entretoise intermédiaire) les deux guides 34, 35 et la bande 36 s'étendent sensiblement parallèlement à la tige de vissage.In the portion constituting the magazine (between the upper spacer and the intermediate spacer) the two guides 34, 35 and the strip 36 extend substantially parallel to the screw rod.
Les deux guides latéraux 34, 35 sont prolongés entre l'entretoise intermédiaire 30 et l'entretoise inférieure 25 par une portion recourbée 37 venant se fixer par son extrémité inférieure de part et d'autre de la fente 29.The two lateral guides 34, 35 are extended between the intermediate spacer 30 and the lower spacer 25 by a bent portion 37 which is fixed by its lower end on either side of the slot 29.
L'entretoise intermédiaire 30 supporte un distributeur D, par l'intermédiaire d'une pièce de support de forme en U5 40 dont l'âme 41 est fixée sur un prolongement vertical de l'âme de l'entretoise 30. Cette pièce de support 40 (figure 6) comprend une aile 41' portant un axe horizontal 42' sur lequel pivote un levier 42 qui bascule dans un plan vertical. L'un des deux bras 43 de ce levier 42 porte une tige 44 qui s'étend dans l'aire de passage d'une butée 47 portée par le chariot 20. Le deuxième bras 48 de ce levier 42 coopère avec l'un des deux bras 49 d'un deuxième levier 50 monté oscillant autour d'un axe vertical 51 qui s'étend dans un évidement réalisé dans l'aile 41'. Le deuxième bras 52 de ce deuxième levier 50 est articulé à un tiroir 53 monté coulissant sur la deuxième aile 41" de la pièce de support 40 de manière à assurer ses déplacements en translation. Ce mécanisme assure donc une conversion du mouvement de translation verticale du chariot 20 (dans sa portion de course dans laquelle la butée 47 vient au contact de la tige 44) en un mouvement de translation horizontale du tiroir 53.The intermediate spacer 30 supports a dispenser D, through a shaped support piece U 5 40, the core 41 is fastened to a vertical extension of the core of the spacer 30. This support piece 40 (Figure 6) comprises a wing 41 'carrying a horizontal axis 42' on which pivots a lever 42 which tilts in a vertical plane. One of the two arms 43 of this lever 42 carries a rod 44 which extends in the area of passage of a stop 47 carried by the carriage 20. The second arm 48 of this lever 42 cooperates with one of the two arms 49 of a second lever 50 mounted oscillating about a vertical axis 51 which extends into a recess formed in the wing 41 '. The second arm 52 of this second lever 50 is articulated to a slide valve 53 slidably mounted on the second wing 41 "of the support piece 40 so as to ensure its displacement in translation, which mechanism thus ensures a conversion of the vertical translation movement of the trolley 20 (in its stroke portion in which the stop 47 comes into contact with the rod 44) in a horizontal translational movement of the slide 53.
Dans cet exemple, le tiroir 53 (figure 8) est constitué par un tronçon tabulaire de section rectangulaire dont l'une des parois principales 54 coulisse dans une glissière portée par l'aile 41 " de la pièce de support 40.In this example, the drawer 53 (FIG. 8) is constituted by a tubular section of rectangular section of which one of the main walls 54 slides in a slideway carried by the flange 41 "of the support piece 40.
L'autre paroi principale 55, parallèle à la première 54, s'étend parallèlement et à faible distance du plan des guides latéraux 34, 35, au niveau de l'extrémité inférieure du magasin M.The other main wall 55, parallel to the first wall 54, extends parallel and at a short distance from the plane of the lateral guides 34, 35, at the lower end of the magazine M.
Cette paroi 55 est fendue par une découpe oblique 56 (sensiblement en forme de S comportant une région centrale horizontale et deux ailes obliques).This wall 55 is slotted by an oblique cutout 56 (substantially S-shaped having a horizontal central region and two oblique wings).
Cette découpe délimite d'un côté une languette supérieure 57 qui est doublée par une pièce en forme de Z, 58 pour former une fourche destinée à chevaucher les deux guides latéraux 34, 35 et, de l'autre côté, dans sa partie inférieure, une languette inférieure 59 qui constitue une pièce d'appui située à l'opposé de la fourche 57-58. L'écart entre le bord supérieur de la fourche 57- 58 et le bord supérieur de la languette 59 est au moins égal à la somme du rayon (ou de la semi-largeur) du collet 3 et du rayon de la surface extérieure du fût 2.This cutout defines on one side an upper tongue 57 which is doubled by a Z-shaped piece, 58 to form a fork intended to overlap the two lateral guides 34, 35 and, on the other side, in its lower part, a lower tongue 59 which constitutes a support piece located opposite the fork 57-58. The gap between the upper edge of the fork 57- 58 and the upper edge of the tongue 59 is at least equal to the sum of the radius (or semi-width) of the collar 3 and the radius of the outer surface of the barrel 2.
L'actionnement du distributeur D par le chariot 20 est conçu de manière à ce que :The actuation of the distributor D by the carriage 20 is designed so that:
- Lorsque le chariot 20 est en position haute, la fourche 57-58 chevauche les deux guides latéraux 34, 35 de manière à retenir par son tut 2 l'élément de fixation 1 situé au bas de la pile contenue dans le magasin M. La languette 59 se trouve alors en dehors de la zone de passage délimitée par les deux guides latéraux 34, 35 de manière à libérer l'élément de fixation 1 qui se trouvait préalablement retenu dans le tiroir 53 et à permettre à cet élément de fixation 1 de descendre le long des guides 34, 35 pour se placer à l'entrée du puits de vissage PV.- When the carriage 20 is in the up position, the fork 57-58 overlaps the two lateral guides 34, 35 so as to retain by its head 2 the fastener 1 at the bottom of the stack contained in the store M. La tongue 59 is then outside the passage zone delimited by the two lateral guides 34, 35 so as to release the fixing element 1 which was previously retained in the drawer 53 and to allow this fixing element 1 to down along the guides 34, 35 to be placed at the entrance of the PV screwing well.
- Lorsque le chariot 20 est déplacé dans le bas en vue d'effectuer le vissage de l'élément de fixation 1 présent à l'entrée du puits de vissage PV, grâce à l'action de la butée 47 sur le dispositif de conversion constitué par les leviers 42, 50, la fourche 57-58 se décale latéralement pour laisser le passage de l'élément de fixation 1 situé en bas de la pile tandis que la languette 59 se dispose en regard de l'intervalle compris entre les deux guides latéraux 34, 35 de manière à retenir cet élément de fixation 1.- When the carriage 20 is moved in the bottom to perform the screwing of the fastener 1 present at the input of the screwing well PV, thanks to the action of the stop 47 on the conversion device constituted by by the levers 42, 50, the fork 57-58 shifts laterally to allow the passage of the fastener 1 at the bottom of the stack while the tongue 59 is arranged opposite the gap between the two guides laterally 34, 35 so as to retain this fastening element 1.
- Le distributeur D demeure dans cette position pendant la course de vissage de l'élément de fixation 1 présent dans le puits PV.- The dispenser D remains in this position during the screwing stroke of the fastener 1 present in the PV well.
- Il est ensuite ramené à sa position initiale lorsque le chariot 20 remonte ensuite vers sa position haute, après vissage dudit élément, grâce à une butée 60 solidaire du tube 33. Dans cet exemple, cette butée 60 consiste en une rondelle montée soudée sur le tube 33. L'entraînement du tube 33 par le chariot 20 s'effectue grâce à une butée 61 axialement réglable prévue à la partie supérieure du tube 33, sur laquelle le chariot 20 vient prendre appui en fin de course vers le haut.- It is then returned to its initial position when the carriage 20 then rises to its upper position, after screwing said element, thanks to a stop 60 integral with the tube 33. In this example, this stop 60 consists of a washer mounted welded to the tube 33. The drive of the tube 33 by the carriage 20 is effected by means of an axially adjustable stop 61 provided for in FIG. upper part of the tube 33, on which the carriage 20 is supported at the end of the race upwards.
- Lors du retour du distributeur D en position initiale, la fourche 57-58 vient à nouveau chevaucher les deux guides latéraux 34, 35 pour retenir l'élément de fixation 1 se trouvant en bas de la pile tandis que l'élément 1 qui était retenu précédemment par la languette 59 est libéré et est aiguillé vers le puits de vissage PV. Au départ de son trajet vers le puits de vissage PV, l'élément de fixation (dans le cas où son collet 3 est de forme polygonale) est orienté convenablement grâce à une butée fixe B portée par la glissière constituée par l'aile 41" de la pièce de support 40.- When returning the distributor D to the initial position, the fork 57-58 is again overlapping the two lateral guides 34, 35 to retain the fixing element 1 at the bottom of the stack while the element 1 which was previously retained by the tongue 59 is released and is switched to the PV screwing well. At the start of its path towards the screwdriving well PV, the fixing element (in the case where its collar 3 is of polygonal shape) is oriented appropriately thanks to a fixed abutment B carried by the slide constituted by the wing 41 " of the support piece 40.
Comme précédemment mentionné, le puits de vissage PV comprend (figure 10), dans sa partie supérieure, des volets escamotables, articulés sur l'entretoise inférieure 25 et rappelés par ressort en position d'obturation. Ces volets 63 servent à retenir temporairement les éléments de fixation 1 par leurs collets 3 jusqu'à ce que la tige de la visseuse 21 exerce sur l'élément de fixation 1 un effort vers le bas pour provoquer l'escamotage. Pour pouvoir l'adapter à la longueur des éléments de fixation, la tige de vissage comprend des embouts interchangeables de longueur appropriée à celle des fûts desdits éléments.As previously mentioned, the PV screwing well comprises (FIG. 10), in its upper part, retractable flaps hinged to the lower spacer 25 and spring-loaded in the closed position. These flaps 63 serve to temporarily retain the fasteners 1 by their collars 3 until the rod of the screwdriver 21 exerts on the fastener 1 a downward force to cause the retraction. In order to adapt it to the length of the fastening elements, the screwing rod comprises interchangeable tips of appropriate length to that of the drums of said elements.
Ce puits de vissage PV comprend deux plaques de guidage 64, 65 sensiblement verticales, de profil légèrement concave (appropriées aux formes des collets 3) disposées l'une en regard de l'autre. L'une de ces deux plaques 65 est articulée dans sa partie inférieure (articulation 66). Les deux plaques 64, 65 présentent dans leurs parties supérieures, des portions obliques 67, 68 formant un évasement. La plaque 65 est sollicitée par des moyens élastiques (ressorts 69) en direction de l'autre plaque 64. Ces deux plaques 64, 65 servent ainsi à assurer un guidage avec autocentrage des éléments de fixation préalablement et pendant le vissage.This PV screwing well comprises two guide plates 64, 65 substantially vertical, slightly concave profile (suitable for the shapes of the collars 3) arranged one facing the other. One of these two plates 65 is articulated in its lower part (articulation 66). The two plates 64, 65 have in their upper parts, oblique portions 67, 68 forming a flare. The plate 65 is biased by resilient means (springs 69) towards the other plate 64. These two plates 64, 65 thus serve to provide guidance with self-centering of the fasteners before and during the screwing.
Avantageusement, pour faciliter leur insertion dans le magasin de l'appareil, les éléments de fixation 1 pourront être préalablement conditionnés de la façon décrite dans la demande de brevet FR No 04 07498 déposée le 6 juillet 2004 au nom de la Demanderesse, grâce à un profilé de support souple présentant au moins en partie la forme d'une bande dont une bordure latérale est munie d'une succession d'encoches débouchant latéralement à l'extérieur par une ouverture rétrécie de largeur inférieure au diamètre des fûts de manière à ce que les fûts puissent s'y engager et y être maintenus par clipsage Z1.Advantageously, to facilitate their insertion into the magazine of the device, the fastening elements 1 may be previously packaged in the manner described in the patent application FR No. 04 07498 filed on July 6, 2004 in the name of the Applicant, thanks to a flexible support profile having at least partly the shape of a band whose side edge is provided with a succession of notches opening laterally outwards through a narrowed opening of width less than the diameter of the barrels so that the drums can engage there and be maintained by clipping Z 1 .
Bien entendu, une fois que les éléments de fixation portés par la bande sont engagés dans le magasin, la bande doit être ôtée. Cette opération est obtenue par une simple traction effectuée au niveau de l'extrémité supérieure de la bande de manière à provoquer un désengagement successif des fûts hors des encoches.Of course, once the fasteners carried by the band are engaged in the magazine, the band must be removed. This operation is obtained by a simple traction performed at the upper end of the strip so as to cause successive disengagement of the barrels out of the notches.
Dans la variante d'exécution illustrée sur les figures 11 à 13, l'appareil de vissage comprend une pluralité de magasins verticaux (ici quatre) M1, M2, M3,In the variant embodiment illustrated in FIGS. 11 to 13, the screwing device comprises a plurality of vertical magazines (here four) M 1 , M 2 , M 3 ,
M4 du type de celui visible sur les figures 4 et 5 et comportant chacun deux guides latéraux parallèles 70, 71 et un guide central 72, ces trois guides 70 àM 4 of the type shown in Figures 4 and 5 and each having two parallel lateral guides 70, 71 and a central guide 72, these three guides 70 to
72 étant reliés sur quatre niveaux (inférieur, supérieur + 2 niveaux intermédiaires) par des brides B1 à B4 constituées par des bandes de métal repliées, en forme de C.72 being connected on four levels (lower, upper + 2 intermediate levels) by flanges B 1 to B 4 consist of folded metal strips, C-shaped.
Les brides B4 du niveau inférieur et celles du niveau intermédiaire supérieur B '2 sont reliées ensemble par deux pièces de liaison respectives 73, 74 de forme circulaire qui s'étendent sur environ 60°. La pièce de liaison 73 située au niveau intermédiaire supérieur présente une section sensiblement en forme de U. Elle est supportée par une platine de support 75 à bord circulaire, de même rayon de courbure que la pièce 74, qui s'étend sur environ 120°.The flanges B 4 of the lower level and those of the upper intermediate level B '2 are connected together by two respective connecting pieces 73, 74 of circular shape which extend over approximately 60 °. The connecting piece 73 located at the upper intermediate level has a substantially U-shaped section. It is supported by a support plate 75 with a circular edge, with the same radius of curvature as the piece 74, which extends over approximately 120 ° .
Cette platine 75 qui s'engage dans la cavité de la pièce de liaison 73 est fixée au sommet des colonnes 18, 19 grâce à deux vis coaxiales V1, V2. Cet assemblage permet un coulissement circulaire de la pièce de liaison 73 sur la platine 75. A cet effet, un système de roulement à billes est prévu entre l'aile supérieure de la pièce de liaison supérieure 73 et la face supérieure de la platine 75. Ce roulement fait intervenir des billes qui s'engagent dans une gorge circulaire coaxiale 76 de la platine 75.This plate 75 which engages in the cavity of the connecting piece 73 is fixed to the top of the columns 18, 19 by means of two coaxial screws V 1 , V 2 . This assembly allows a circular sliding of the connecting piece 73 on the plate 75. For this purpose, a ball bearing system is provided between the upper flange of the upper connecting piece 73 and the upper face of the plate 75. This bearing involves balls that engage in a coaxial circular groove 76 of the plate 75.
Grâce à ces dispositions, il est possible de faire pivoter la structure rotative comprenant les magasins M1 à M4 et les pièces de liaison 73, 74 de manière à amener successivement l'orifice inférieur de chacun des magasins au droit du distributeur D. (Ce distributeur D, de même que la partie inférieure de l'appareil est similaire à celle de l'appareil précédemment décrit en regard des figures 1 à 10 et ne sera donc pas décrit à nouveau.)Thanks to these arrangements, it is possible to rotate the rotary structure comprising the magazines M 1 to M 4 and the connecting pieces 73, 74 so as successively to bring the lower orifice of each of the magazines to the distributor D. This distributor D, as well as the lower part of the apparatus is similar to that of the apparatus previously described with reference to Figures 1 to 10 and will not be described again.)
L'orifice inférieur de chacun des magasins M1 à M4 est équipé d'un obturateur O1 à O4 faisant intervenir deux broches radiales 77, 78 passant au travers de deux passages respectifs prévus dans l'âme de la bride B4 du magasin et solidaire d'une pièce d'actionnement 79 montée coulissante avec rappel par ressort 80 sur une tige radiale 81, solidaire de la bride B4, qui s'étend à l'opposé des broches 77, 78.The lower orifice of each of the magazines M 1 to M 4 is equipped with a shutter O 1 to O 4 involving two radial pins 77, 78 passing through two respective passages provided in the web of the flange B 4 of the store and secured to an actuating piece 79 mounted sliding with spring return 80 on a radial rod 81, integral with the flange B 4 , which extends opposite the pins 77, 78.
Cette pièce d'actionnement 79 est quant à elle munie d'un doigt vertical 82 destiné à coopérer avec un profil de came 82' d'une pièce d'actionnement fixe 83 solidaire de la structure du distributeur D. Grâce à ces dispositions lorsqu'un magasin M1 à M4 n'est pas dans l'axe du distributeur D la pièce d'actionnement 79 de l'obturateur O1 à O4 est repoussée par le ressort 80 de manière à ce que les broches 77, 78 s'engagent en travers de la section de passage du magasin et retienne les éléments de fixation contenus dans ce magasin.This actuating piece 79 is itself provided with a vertical finger 82 intended to cooperate with a cam profile 82 'of a fixed actuating part 83 integral with the structure of the distributor D. Thanks to these provisions when a magazine M 1 to M 4 is not in the axis of the distributor D the actuating part 79 of the shutter O 1 to O 4 is pushed by the spring 80 so that the pins 77, 78 engage across the magazine passage section and retain the fasteners contained in this magazine.
Lorsque ce magasin est amené dans l'axe du distributeur D, le doigt 82 sollicité par le profil de came 82' provoque un retrait de la pièce d'actionnement 19, contre l'action du ressort 80, et en conséquence un retrait des broches 77, 78. Lorsque le magasin est exactement dans l'axe du distributeur D, les broches 77, 78 se trouvent en dehors de la section de passage des éléments de fixation et, de ce fait, ces éléments de fixation descendent dans le distributeur D par simple gravité.When this magazine is brought into the axis of the distributor D, the finger 82 urged by the cam profile 82 'causes a withdrawal of the actuating part 19, against the action of the spring 80, and consequently a removal of the pins 77, 78. When the magazine is exactly in the axis of the dispenser D, the pins 77, 78 are outside the passage section of the fasteners and, therefore, these fasteners descend into the dispenser D by simple gravity.
Avantageusement, le profil de came 82' pourra comprendre une encoche servant à marquer le passage du magasin au droit du distributeur D et de le maintenir temporairement dans cette position (à la façon d'un cliquet).Advantageously, the cam profile 82 'may comprise a notch used to mark the passage of the magazine to the right of the distributor D and temporarily hold it in this position (in the manner of a pawl).
Grâce à ces dispositions, lorsque l'opérateur a vidé un magasin M1 à M4, par une simple rotation de la structure rotative, il met en service le magasin suivant. Il dispose ainsi d'un nombre important d'éléments de fixation.Thanks to these arrangements, when the operator has emptied a magazine M 1 to M 4 , by a simple rotation of the rotary structure, it puts into service the next store. It thus has a large number of fasteners.
Par ailleurs, comme ceci est visible sur la figure 11, la visseuse/dévisseuse 21 n'est pas montée directement sur le chariot 20 mais sur un coulisseau 95 réglable en hauteur sur le chariot 20. A cet effet, le coulisseau 95 comprend deux profilés latéraux de guidage 96, 91 qui s'engagent sur deux languettes latérales de guidage 83, 84 solidaires du chariot 20. Le positionnement axial du coulisseau 95 le long de ces languettes 83, 84 est assuré par un mécanisme de verrouillage faisant intervenir :Furthermore, as can be seen in FIG. 11, the screwdriver 21 is not mounted directly on the carriage 20 but on a slide 95 that is adjustable in height on the carriage 20. For this purpose, the slide 95 comprises two profiles lateral guiding 96, 91 which engage on two lateral guide tabs 83, 84 secured to the carriage 20. The axial positioning of the slide 95 along these tongues 83, 84 is provided by a locking mechanism involving:
- une série de perçages 85 réalisés sur la languette 83, - un pointeau monté coulissant dans l'une des ailes du profilé latéral 96, perpendiculairement au plan des languettes 83, 84, et sollicité vers celles-ci par un ressort. L'actionnement de ce pointeau est assuré au moyen d'une poignée 86.a series of holes 85 made on tongue 83, - A needle mounted slidably in one of the wings of the lateral section 96, perpendicular to the plane of the tongues 83, 84, and biased towards them by a spring. The actuation of this needle is provided by means of a handle 86.
Grâce à ces dispositions, pour régler la position du coulisseau 95, dans un premier temps on effectue une traction sur le pointeau grâce à la poignée 86, de manière à le désassembler du perçage 85 de la languette 83 dans lequel il se trouvait engagé puis on déplace le coulisseau 95 jusqu'à ce qu'il se trouve dans la position souhaitée. On relâche alors le pointeau de manière à ce qu'il puisse s'engager dans un perçage 85 de la languette 83 correspondant à cette position.With these provisions, to adjust the position of the slide 95, in a first step is performed a traction on the needle through the handle 86, so as to disassemble the hole 85 of the tongue 83 in which it was engaged then moves the slider 95 until it is in the desired position. The needle is then released so that it can engage in a hole 85 of the tongue 83 corresponding to this position.
Ce réglage en hauteur de la visseuse/dévisseuse 21 permet d'utiliser des éléments de fixation de tailles différentes sans avoir à modifier la longueur de la tige de vissage 31. La position des trous 85 pourra avantageusement mais non exclusivement correspondre à la hauteur des principaux éléments de fixation disponibles dans le commerce.This height adjustment of the screwdriver 21 makes it possible to use fasteners of different sizes without having to modify the length of the screwing rod 31. The position of the holes 85 may advantageously but not exclusively correspond to the height of the main fasteners available commercially.
Dans cette variante d'exécution la tige de vissage 31 est disposée à l'intérieur d'un élément tubulaire coaxial ET, mobile axialement (verticalement). Cet élément tubulaire ET comprend un tronçon inférieur 87 de diamètre intérieur légèrement supérieur au diamètre de la tige 31 et un tronçon supérieur 88 de diamètre intérieur légèrement supérieur au diamètre de la partie extrême 89 du nez de la visseuse/dévisseuse 21.In this variant embodiment, the screwing rod 31 is disposed inside a coaxial tubular element ET, axially movable (vertically). This tubular element ET comprises a lower section 87 of inner diameter slightly greater than the diameter of the rod 31 and an upper section 88 of inside diameter slightly greater than the diameter of the end portion 89 of the nose of the screwdriver 21.
Le tronçon inférieur 87 coulisse dans un perçage 98 réalisé dans une entretoise 90 reliant les deux glissières latérales de guidage des éléments de fixation, à l'extrémité de la position recourbée 37 s'étendant au-dessus du puits de vissage. Le tronçon 88 comprend une collerette supérieure évasée 91. Il coulisse dans un perçage réalisé dans le fond d'un puits 92 solidaire d'une pièce de liaison 93 du chariot 20.The lower section 87 slides in a bore 98 made in a spacer 90 connecting the two lateral guide rails of the fasteners, at the end of the curved position 37 extending above the screw well. The section 88 comprises a flared upper flange 91. It slides in a hole made in the bottom of a well 92 secured to a connecting piece 93 of the carriage 20.
Une rondelle de butée 94 est disposée au niveau de la jonction entre les deux tronçons 87, 88.A thrust washer 94 is disposed at the junction between the two sections 87, 88.
L'élément tabulaire ET sert à exercer une pression sur le collet 3 de l'élément de fixation 1 au cours de son vissage.The tabular element ET serves to exert pressure on the collar 3 of the fixing element 1 during its screwing.
Lorsque le chariot 20 est en position haute, l'élément tabulaire ET est suspendu en position haute par le fond du puits 92 grâce à la collerette 91.When the carriage 20 is in the high position, the tabular element ET is suspended in the high position by the bottom of the well 92 thanks to the flange 91.
Lorsque le chariot 20 est abaissé, l'extrémité inférieure de l'élément ET vient porter sur le collet 3 de l'élément de fixation 1 présent dans le puits de vissage PV en même temps que l'extrémité de la tige de vissage vient en prise avec la tête de vis 5.When the carriage 20 is lowered, the lower end of the element ET comes to bear on the collar 3 of the fastening element 1 present in the PV screwing well at the same time that the end of the screwing rod comes into taken with the screw head 5.
Au cours de la phase de vissage, l'extrémité de l'élément tabulaire ET repousse le collet 3 jusqu'à la fin du vissage. During the screwing phase, the end of the tabular element ET pushes the collar 3 until the end of the screwing.
