Description Description
Titre : OUTIL DE VISSAGE COMPRENANT UN MOYEN D’ABRASION Title: TIGHTENING TOOL COMPRISING AN ABRASION MEANS
Le domaine de la présente invention est celui de l’outillage pour vissage, notamment utilisé dans le secteur du bâtiment et de la construction. La présente invention trouve une application particulièrement intéressante aux panneaux de construction utilisés, par exemple, pour réaliser des cloisons, des murs, des sols ou des plafonds ou pour habiller tout ou partie de telles surfaces. The field of the present invention is that of tooling for screwing, in particular used in the building and construction sector. The present invention finds a particularly interesting application to building panels used, for example, to make partitions, walls, floors or ceilings or to cover all or part of such surfaces.
Les panneaux de construction sont des plaques faites d’un matériau choisi en fonction de son emploi. A titre indicatif, on peut citer des panneaux de construction comprenant du plâtre, du ciment, du bois ou des particules de bois, des matériaux synthétiques, des fibres mélangées, des particules minérales, ou un mélange de ces matériaux, ces panneaux de construction pouvant en outre être recouverts d’un revêtement de surface en une matière distincte du matériau choisi. Construction panels are plates made of a material chosen according to its use. As an indication, mention may be made of construction panels comprising plaster, cement, wood or wood particles, synthetic materials, mixed fibers, mineral particles, or a mixture of these materials, these construction panels being able to furthermore be covered with a surface coating of a material distinct from the material chosen.
Les panneaux de construction sont fixés sur un support. Cette fixation, réalisée au moyen de vis de fixation insérées dans le support à travers le panneau de construction, assure que chaque panneau de construction est solidaire du support. Typiquement, les vis de fixation traversent le panneau de construction et sont vissées, puis serrées, dans le support, de telle manière qu'une tête des vis de fixation se trouve insérée dans l'épaisseur du panneau de construction, et affleure à la surface de ce dernier. The construction panels are fixed on a support. This fixing, carried out by means of fixing screws inserted into the support through the construction panel, ensures that each construction panel is integral with the support. Typically, the fixing screws pass through the construction panel and are screwed, then tightened, in the support, so that a head of the fixing screws is inserted into the thickness of the construction panel, and is flush with the surface. of the last.
Les opérations de vissage des vis de fixation dans un support d'un panneau de construction, et de serrage de ce panneau de construction contre le support, peuvent parfois s'accompagner de défauts, notamment esthétiques, qui nuisent à l'aspect visuel de la finition ultérieure, par exemple lors de l’application d'un enduit et/ou d’une peinture qui viennent couvrir au moins en partie le panneau de construction considéré. The operations of screwing the fixing screws into a support of a construction panel, and of tightening this construction panel against the support, can sometimes be accompanied by defects, in particular aesthetic, which adversely affect the visual appearance of the subsequent finishing, for example during the application of a coating and / or a paint which at least partially covers the construction panel considered.
Le problème technique auquel la présente invention propose d'apporter une solution est celui d'un défaut visuel désigné sous l'appellation de "larmes de papier". Un tel défaut se produit par exemple sur un panneau de construction tel qu'une plaque de plâtre formée d'une couche de plâtre interposée entre deux feuilles de parement, généralement en carton. Un tel défaut visuel se rapporte à un cas dans lequel, lorsque la tête d'une vis de fixation pénètre dans l'épaisseur du panneau de construction, il peut se produire un arrachement partiel et discontinu de la matière formant la feuille de parement. Cet arrachement forme une matière solide qui, si il n’est pas totalement retiré de la surface du panneau de construction, se mêle à l’enduit ou à la peinture et dégrade l’état de surface final de la couche de finition. The technical problem to which the present invention proposes to provide a solution is that of a visual defect designated under the name of "tears of paper". Such a defect occurs for example on a construction panel such as a plate of plaster formed of a layer of plaster interposed between two facing sheets, generally made of cardboard. Such a visual defect relates to a case in which, when the head of a fixing screw penetrates into the thickness of the building panel, there may occur a partial and discontinuous tearing of the material forming the facing sheet. This tearing forms a solid material which, if it is not completely removed from the surface of the construction panel, mixes with the plaster or paint and degrades the final surface condition of the top coat.
L'invention a pour but de proposer une solution permettant d’éviter l’apparition d’un tel défaut de finition, tout en garantissant une fixation fiable et reproductible des panneaux de construction sur leur support. Pour ce faire, l’invention met en œuvre un nettoyage par frottement d’une zone périphérique à la tête de vis de fixation, pendant l’étape de serrage de celle-ci. The object of the invention is to propose a solution making it possible to avoid the appearance of such a defect in finishing, while guaranteeing a reliable and reproducible fixing of the construction panels on their support. To do this, the invention implements a friction cleaning of a peripheral zone to the head of the fixing screw, during the tightening step thereof.
Dans ce but, l'invention a pour objet un outil de vissage configuré pour transmettre une rotation à une vis de fixation d'un panneau de construction sur un support, l'outil de vissage comprenant au moins un embout de vissage configuré pour coopérer avec une tête de la vis de fixation, caractérisé en ce que l’embout de vissage porte un moyen d'abrasion amovible configuré pour frotter sur le panneau de construction dans lequel la vis de fixation est logée. To this end, the subject of the invention is a screwing tool configured to transmit a rotation to a screw for fixing a construction panel on a support, the screwing tool comprising at least one screwing tip configured to cooperate with a head of the fixing screw, characterized in that the screwing piece carries a removable abrasion means configured to rub on the construction panel in which the fixing screw is housed.
Le moyen d’abrasion est agencé par rapport à l’embout de vissage de façon à frotter le panneau de construction au moins lorsque la tête de la vis de fixation se trouve en contact avec le panneau de construction. L’embout de vissage comprend ainsi une portion distale utile conformée pour coopérer avec la tête de la vis de fixation, et le moyen d’abrasion surmonte ou entoure au moins partiellement ladite portion utile, de façon à venir en contact avec le panneau de construction au moins lorsque la tête de la vis de fixation est en contact avec ce panneau de construction. The abrading means is arranged relative to the screw-in end so as to rub the construction panel at least when the head of the fixing screw is in contact with the construction panel. The screwing tip thus comprises a useful distal portion shaped to cooperate with the head of the fixing screw, and the abrasion means at least partially overcomes or surrounds said useful portion, so as to come into contact with the construction panel. at least when the head of the fixing screw is in contact with this building panel.
Selon un aspect de l’invention, le moyen d’abrasion est mécaniquement lié à l’embout de vissage. Ce lien mécanique est un blocage mécanique qui interdit toute rotation entre le moyen d'abrasion et l’embout de vissage. De manière complémentaire, ce lien mécanique est un blocage mécanique qui interdit toute translation entre le moyen d'abrasion et l’embout de vissage, le long de l’outil de vissage, au moins dans un sens qui tend à éloigner le moyen d’abrasion de la portion distale de l’embout de vissage qui est destinée à coopérer avec la tête de la vis de fixation. According to one aspect of the invention, the abrasion means is mechanically linked to the screwing tip. This mechanical link is a mechanical blocking which prevents any rotation between the abrasion means and the screwdriver bit. In addition, this mechanical link is a mechanical block which prevents any translation between the means abrasion and the screwdriver bit, along the screwing tool, at least in one direction which tends to move the abrasion means away from the distal portion of the screwdriver bit which is intended to cooperate with the fixing screw head.
Le terme de vissage désigne génériquement ici, ainsi que dans ce qui suit, les opérations successives de vissage et de blocage d'une vis de fixation qui conduisent à la fixation d'un panneau de construction sur un support de celui-ci. The term screwing generically designates here, as well as in what follows, the successive operations of screwing and blocking a fixing screw which lead to the fixing of a construction panel on a support thereof.
Une vis de fixation d'un panneau de construction sur un support à laquelle s’applique l’outil de vissage selon l’invention comprend une partie filetée et une tête de forme extérieure conique. La partie filetée est sensiblement cylindrique et elle se termine, à l'une de ses extrémités selon sa direction principale d'extension, par une portion formant une pointe. A son extrémité opposée selon la direction principale d'extension précitée, la partie filetée de la vis de fixation est rattachée à la tête précédemment évoquée. Cette dernière présente avantageusement une forme de révolution évasée, coaxiale avec l'axe de révolution de la partie filetée de la vis de fixation. A screw for fixing a building panel to a support to which the screwing tool according to the invention is applied comprises a threaded part and a conically shaped head. The threaded part is substantially cylindrical and it ends, at one of its ends in its main direction of extension, by a portion forming a point. At its opposite end in the aforementioned main direction of extension, the threaded part of the fixing screw is attached to the head mentioned above. The latter advantageously has a flared form of revolution, coaxial with the axis of revolution of the threaded part of the fixing screw.
Avantageusement, une surface supérieure de la tête de la vis de fixation est sensiblement plane. Selon différents exemples, la surface supérieure de la tête de vis de fixation peut comporter une empreinte femelle, ou elle peut comporter une forme mâle. Dans un tel cas, l’embout de vissage présente une forme complémentaire à la forme de l’empreinte que la tête de la vis de fixation comporte. Advantageously, an upper surface of the head of the fixing screw is substantially planar. According to different examples, the upper surface of the head of the fixing screw can have a female imprint, or it can have a male shape. In such a case, the screwing tip has a shape complementary to the shape of the imprint that the head of the fixing screw has.
Pour réaliser la fixation d'un panneau de construction sur un support, une vis de fixation telle que décrite ci-dessus est positionnée sur une face principale du panneau de construction, sensiblement perpendiculairement à celle-ci, la pointe étant placée en contact avec la face principale précitée. La vis de fixation est ensuite vissée pour, successivement, perforer la face principale précitée, puis traverser l'épaisseur du panneau de construction, puis perforer le support, et, enfin, être bloquée par serrage dans le support. Lorsque l'opération de fixation du panneau de construction sur le support est terminée, la surface supérieure de la tête de la vis de fixation affleure la face principale du panneau de construction. En d'autres termes, à l'issue de l'opération de fixation du panneau de construction sur le support, la surface supérieure d'une vis de fixation telle que précédemment évoquée est coplanaire avec la face exposée du panneau de construction. To fix a building panel to a support, a fixing screw as described above is positioned on a main face of the building panel, substantially perpendicular to it, the point being placed in contact with the main face mentioned above. The fixing screw is then screwed in order to successively perforate the aforementioned main face, then pass through the thickness of the construction panel, then perforate the support, and finally be locked by clamping in the support. When the operation of fixing the construction panel to the support is complete, the upper surface of the head of the fixing screw is flush with the main face of the construction panel. In other words, at the end of the operation of fixing the construction panel to the support, the upper surface of a fixing screw such that previously mentioned is coplanar with the exposed face of the construction panel.
L’embout de vissage d'un outil de vissage selon l'invention présente une forme allongée selon un axe principal d'allongement qui est également axe de révolution pour l’embout de vissage et pour l'outil de vissage selon l'invention. A l'une de ses extrémités selon sa direction principale d'allongement, l’embout de vissage présente une forme configurée pour coopérer avec la surface supérieure de la vis de fixation précédemment décrite. Selon un exemple, cette forme comprend une partie mâle configurée pour s'insérer dans une empreinte femelle agencée dans la surface supérieure de la tête de la vis de fixation. Selon un autre exemple, l’embout de vissage comprend une empreinte femelle configurée pour recevoir une partie mâle agencée à la surface supérieure de la tête de la vis de fixation. Dans un tel cas, la partie mâle est enterrée dans la tête de la vis de fixation. The screwing tip of a screwing tool according to the invention has an elongated shape along a main elongation axis which is also axis of revolution for the screwing tip and for the screwing tool according to the invention. At one of its ends in its main direction of elongation, the screwing tip has a shape configured to cooperate with the upper surface of the previously described fixing screw. According to an example, this form comprises a male part configured to fit into a female imprint arranged in the upper surface of the head of the fixing screw. In another example, the screwdriver bit comprises a female imprint configured to receive a male part arranged on the upper surface of the head of the fixing screw. In such a case, the male part is buried in the head of the fixing screw.
Lors d'une opération de fixation d'un panneau de construction sur un support, l'outil de vissage est placé de telle manière que l'axe de révolution de l’embout de vissage est sensiblement confondu avec l'axe de révolution de la vis de fixation. Entraîné en rotation autour de l'axe de révolution de l’embout de vissage, l'outil de vissage entraîne alors à son tour la vis de fixation en rotation autour de son axe de révolution, grâce à la coopération de la forme d'extrémité de l’embout de vissage avec la surface supérieure de la tête de la vis de fixation. During an operation of fixing a construction panel to a support, the screwing tool is placed in such a way that the axis of revolution of the screwing bit is substantially coincident with the axis of revolution of the screw. Rotated around the axis of revolution of the screwdriver bit, the screwing tool then in turn drives the fixing screw in rotation around its axis of revolution, thanks to the cooperation of the end shape of the screwdriver bit with the upper surface of the head of the fixing screw.
Selon l'invention, un moyen d'abrasion est configuré pour frotter sur le panneau de construction dans lequel la vis de fixation est insérée. Plus précisément, en référence aux dénominations précédemment définies, le moyen d'abrasion de l'outil de vissage selon l'invention comprend une face configurée pour frotter contre la face exposée du panneau de construction considéré. Par convention, la face du moyen d'abrasion configurée pour frotter contre la face exposée du panneau de construction sera désignée dans ce qui suit comme surface de frottement. Il s’agit de la face active du moyen d'abrasion. Avantageusement, cette surface de frottement est sensiblement plane, et elle est sensiblement perpendiculaire à l'axe de révolution de l’embout de vissage. De manière avantageuse, le moyen d’abrasion est disposé de manière à frotter seulement la face exposée du panneau. Ce frottement est réalisé autour de la vis de fixation, une fois celle-ci en place. According to the invention, an abrasion means is configured to rub on the construction panel in which the fixing screw is inserted. More specifically, with reference to the previously defined names, the means of abrasion of the screwing tool according to the invention comprises a face configured to rub against the exposed face of the construction panel considered. By convention, the face of the abrasion means configured to rub against the exposed face of the building panel will be designated in the following as a friction surface. This is the active side of the abrasion medium. Advantageously, this friction surface is substantially planar, and it is substantially perpendicular to the axis of revolution of the screwing tip. Advantageously, the abrasion means is arranged so as to rub only the exposed face of the panel. This friction is produced around the fixing screw, once the latter in place.
Selon un aspect, l'invention prévoit que le moyen d'abrasion est lié en rotation avec l’embout de vissage. Un tel lien est par exemple mécanique, par collage, montage à force ou complémentarité de formes. En d'autres termes, le moyen d'abrasion et l’embout de vissage sont configurés pour être simultanément entraînés en rotation. Il s'ensuit que le frottement du moyen d'abrasion sur le panneau de construction et le vissage de la vis de fixation s'effectuent simultanément. According to one aspect, the invention provides that the abrasion means is linked in rotation with the screwdriver bit. Such a link is for example mechanical, by gluing, force fitting or complementary shapes. In other words, the abrasion means and the screwing tip are configured to be simultaneously rotated. It follows that the friction of the abrasion means on the construction panel and the screwing of the fixing screw are carried out simultaneously.
Selon un aspect avantageux de l'invention, le moyen d'abrasion est coaxial avec l’embout de vissage. Il en résulte que le frottement du moyen d'abrasion contre la face exposée du panneau de construction est réalisé sur une surface centrée sur l'axe de l’embout de vissage, c’est-à-dire dans la zone où les défauts peuvent apparaître. According to an advantageous aspect of the invention, the abrasion means is coaxial with the screwdriver bit. As a result, the friction of the abrasion means against the exposed face of the construction panel is carried out on a surface centered on the axis of the screwdriver bit, that is to say in the zone where the defects can appear.
Selon un exemple de réalisation de l'invention, le moyen d'abrasion est amovible par rapport à l’outil de vissage. Il peut, par exemple, être enfilé sur l’embout de vissage, en étant par exemple emboîté sur celui-ci. Dans ce cas, le moyen d’abrasion peut être considéré comme un élément d'usure de l'outil de vissage selon l'invention et il peut être facilement remplacé si ses propriétés abrasives diminuent. According to an exemplary embodiment of the invention, the abrasion means is removable relative to the screwing tool. It can, for example, be threaded onto the screwdriver bit, for example by being fitted on it. In this case, the abrasion means can be considered as a wear element of the screwing tool according to the invention and it can be easily replaced if its abrasive properties decrease.
Selon un exemple de réalisation de l'invention, le moyen d'abrasion est une pièce solidaire et indémontable de l’embout de vissage sans destruction, par exemple par collage ou encore par insertion en force, autour de la tête de l'outil de vissage. According to an exemplary embodiment of the invention, the abrasion means is an integral and non-removable part of the screwdriver bit without destruction, for example by gluing or by force insertion, around the head of the tool. screwing.
Quel que soit le mode de liaison mécanique entre le moyen d'abrasion et l’embout de vissage, l'invention prévoit que la surface de frottement du moyen d'abrasion s'étend sensiblement dans un plan compris entre une extrémité de l’embout de vissage porteuse de la forme configurée pour coopérer avec la surface supérieure d'une vis de fixation et une extrémité opposée de l’embout de vissage, selon la direction principale d'allongement de ce dernier. Plus précisément, une distance, mesurée selon la direction principale d'allongement de l’embout de vissage, entre l'extrémité de l’embout de vissage destinée à coopérer avec la vis de fixation et la surface de frottement du moyen d'abrasion est non nulle. Autrement dit, selon la direction de l'axe de révolution de l’embout de vissage, l'extrémité de l’embout de vissage qui coopère avec la vis de fixation émerge du moyen d'abrasion. Whatever the mode of mechanical connection between the abrasion means and the screwing tip, the invention provides that the friction surface of the abrasion means extends substantially in a plane between one end of the tip screwing carrier of the shape configured to cooperate with the upper surface of a fixing screw and an opposite end of the screwing tip, in the main direction of elongation of the latter. More precisely, a distance, measured along the main direction of elongation of the screwing tip, between the end of the screwing tip intended to cooperate with the fixing screw and the friction surface of the abrasion means is no nothing. In other words, according to the direction of the axis of revolution of the screwing tip, the end of the screwing tip which cooperates with the fixing screw emerges from the abrasion means.
Selon un exemple de réalisation, le moyen d'abrasion comprend au moins une pièce d’abrasion réalisée dans un matériau abrasif. Il faut comprendre ici que la pièce précitée est une pièce massive, par exemple une pièce cylindrique coaxiale avec l’embout de vissage de l'outil selon l'invention. A titre d'exemples non exhaustifs, la pièce d’abrasion peut être une gomme réalisée, par exemple, dans un matériau élastomère, ou il peut être formé d’un substrat porteur de grains de matériaux céramiques ou siliciques inclus dans une résine polymère. Le moyen d'abrasion peut également être formé d'une couche d'un matériau abrasif rapportée sur un support. According to an exemplary embodiment, the abrasion means comprises at least one abrasion piece made of an abrasive material. It should be understood here that the aforementioned part is a solid part, for example a cylindrical part coaxial with the screwing end of the tool according to the invention. By way of non-exhaustive examples, the abrasion piece can be a rubber made, for example, from an elastomeric material, or it can be formed from a substrate carrying grains of ceramic or silicic materials included in a polymer resin. The abrasion means can also be formed from a layer of abrasive material attached to a support.
De manière alternative au caractère massif de la pièce d’abrasion, l’invention couvre également une situation où le moyen d’abrasion comprend une pluralité de pièces d’abrasion sous forme de sections angulaires séparées les unes des autres et faites d’un matériau abrasif. As an alternative to the massive nature of the abrasion piece, the invention also covers a situation where the abrasion means comprises a plurality of abrasion pieces in the form of angular sections separated from each other and made of a material abrasive.
Selon un exemple, le moyen d’abrasion comporte des moyens, notamment élastiques, destinés à solliciter la et les pièces d’abrasion en direction de l’extrémité distale de l’embout de vissage. According to one example, the abrasion means comprises means, in particular elastic means, intended to urge the and the abrasion pieces towards the distal end of the screwdriver bit.
Le moyen d'abrasion comprend, selon un aspect de l'invention, au moins un organe élastique configuré pour maintenir la ou les pièces d'abrasion plaquées contre le panneau de construction. Il faut comprendre ici que l’organe élastique est configuré pour exercer une force de pression sur la ou les pièces d'abrasion, en direction de l'extrémité de l’embout de vissage destinée à coopérer avec la vis de fixation. L’organe élastique précité est ainsi configuré pour compenser une usure éventuelle de la ou des pièces d'abrasion, afin de maintenir un contact mécanique entre cette pièce d’abrasion et la face exposée du panneau de construction contre laquelle la ou les pièces d'abrasion frottent. The abrasion means comprises, according to one aspect of the invention, at least one elastic member configured to hold the abrasion piece or pieces pressed against the construction panel. It should be understood here that the elastic member is configured to exert a pressing force on the abrasion piece or pieces, in the direction of the end of the screwing tip intended to cooperate with the fixing screw. The aforementioned elastic member is thus configured to compensate for possible wear of the abrasion piece or pieces, in order to maintain mechanical contact between this abrasion piece and the exposed face of the building panel against which the piece or pieces of abrasion rub.
Selon un aspect de l'invention, l'outil de vissage comporte une paroi solidaire de l’embout de vissage et formant butée pour l’organe élastique précité. Selon un exemple avantageux, la paroi formant butée comporte au moins une portion se présentant sous la forme d'un disque coaxial avec l’embout de vissage et sensiblement perpendiculaire à l'axe de révolution de cette dernière. L'invention prévoit que, en l'absence d'usure de la ou des pièces d'abrasion, l’organe élastique précédemment défini est comprimé entre cette dernière et la paroi formant butée. According to one aspect of the invention, the screwing tool comprises a wall integral with the screwing tip and forming a stop for the above-mentioned elastic member. According to an advantageous example, the wall forming a stop comprises at least one portion appearing under the form of a coaxial disc with the screwing tip and substantially perpendicular to the axis of revolution of the latter. The invention provides that, in the absence of wear of the abrasion part or parts, the elastic member previously defined is compressed between the latter and the wall forming a stop.
Selon un autre aspect de l'invention, la paroi formant butée forme, avec une bague, une cloche qui reçoit l’organe élastique et au moins une partie de la ou des pièces d’abrasion. La paroi et la bague délimitent une cavité de réception de l’organe élastique précédemment évoqué, cavité dans laquelle s'étend également tout ou partie de la ou des pièces d'abrasion. Selon un exemple, la cloche est sensiblement cylindrique et coaxiale avec l'axe de révolution de l’embout de vissage, cloche qui encapuchonné l’organe élastique et au moins une partie de la ou des pièces d'abrasion. According to another aspect of the invention, the wall forming a stop forms, with a ring, a bell which receives the elastic member and at least part of the abrasion piece or pieces. The wall and the ring delimit a cavity for receiving the elastic member previously mentioned, a cavity in which also extends all or part of the abrasion part or parts. According to one example, the bell is substantially cylindrical and coaxial with the axis of revolution of the screwdriver bit, a bell which encapsulates the elastic member and at least part of the abrasion piece or pieces.
Selon un autre exemple de réalisation, le moyen d'abrasion comprend une brosse. Selon cet exemple, des poils de la brosse se présentent sous la forme de brins flexibles dont la direction principale d'extension est sensiblement parallèle à l'axe de révolution de l’embout de vissage. According to another exemplary embodiment, the abrasion means comprises a brush. In this example, bristles of the brush are in the form of flexible strands whose main direction of extension is substantially parallel to the axis of revolution of the screwdriver bit.
A titre d'exemples non exhaustifs, les poils de la brosse peuvent être réalisés dans un matériau synthétique, dans un matériau métallique ou dans un matériau synthétique recouvert d'une couche métallique. Avantageusement, l'invention prévoit que les poils d'une telle brosse sont fixés sur une base sensiblement annulaire placée perpendiculairement à la direction principale d'allongement de l’embout de vissage. Chaque poil de la brosse constituant le moyen d'abrasion comporte donc une extrémité par laquelle il est fixé à la base précitée et une extrémité libre par laquelle il peut frotter contre la face exposée d'un panneau de construction. La surface de frottement du moyen d'abrasion, précédemment définie, est alors définie par l'ensemble des extrémités libres des poils de la brosse. By way of non-exhaustive examples, the bristles of the brush can be made from a synthetic material, from a metallic material or from a synthetic material covered with a metallic layer. Advantageously, the invention provides that the bristles of such a brush are fixed on a substantially annular base placed perpendicular to the main direction of elongation of the screwdriver bit. Each bristle of the brush constituting the abrasion means therefore has one end by which it is fixed to the aforementioned base and a free end by which it can rub against the exposed face of a building panel. The friction surface of the abrading means, previously defined, is then defined by all of the free ends of the bristles of the brush.
Une telle configuration permet de faciliter l'évacuation, entre les poils de la brosse, des poussières générées par l'abrasion de la face exposée du panneau de construction. Such a configuration makes it possible to facilitate the evacuation, between the bristles of the brush, of the dust generated by abrasion of the exposed face of the construction panel.
Selon un exemple, les poils de la brosse précitée présentent tous la même dimension selon leur direction principale d'extension. Avantageusement, et de manière analogue à l'exemple dans lequel le moyen d'abrasion comprend une ou plusieurs pièces d'abrasion, cette dimension est définie de telle manière qu'une distance, mesurée selon la direction principale d'allongement de l’embout de vissage, entre l'extrémité de l’embout de vissage destinée à coopérer avec la vis de fixation, et la surface de frottement du moyen d'abrasion définie par les extrémités libres des poils de la brosse, est non nulle. According to one example, the bristles of the aforementioned brush all have the same dimension according to their main direction of extension. Advantageously, and similarly to the example in which the abrading means comprises one or more abrading pieces, this dimension is defined in such a way that a distance, measured along the main direction of elongation of the screwing tip, between the end of the screwing tip intended to cooperate with the fixing screw, and the friction surface of the abrasion means defined by the free ends of the bristles of the brush, is not zero.
L'invention, telle qu'elle vient d'être décrite, propose donc de réunir, dans un même outil de vissage, des composants ayant une fonction de fixation d'un panneau de construction sur un support de celui-ci, et des composants ayant une fonction de pré finition d'une face exposée d'un tel panneau de construction. Plus précisément, l'invention permet, grâce à un outil de vissage tel qu'il vient d'être décrit, d'évacuer de la face exposée du panneau de construction d'éventuelles particules arrachées à cette face, et de réaliser cette évacuation dans le même temps que l'opération de vissage. The invention, as just described, therefore proposes to bring together, in the same screwing tool, components having a function of fixing a construction panel to a support thereof, and components having a function of pre-finishing an exposed face of such a construction panel. More specifically, the invention makes it possible, thanks to a screwing tool as just described, to evacuate from the exposed face of the construction panel any particles torn from this face, and to carry out this evacuation in the same time as the screwing operation.
Par la mise en œuvre de moyens simples et peu coûteux, l'invention atteint donc bien le but qu'elle s'était fixé en permettant de supprimer d’une part des défauts visuels de vissage tels que ceux connus sous l'appellation de "larmes de papier" et d’autre part les conséquences que ces défauts peuvent avoir pour la finition de la face exposée. Il est à noter que si l'invention trouve une application privilégiée à la fixation de panneaux de construction tels que des plaques de plâtre, elle s'applique de manière non limitative à tout type de panneau de construction. By implementing simple and inexpensive means, the invention therefore achieves the goal it set for itself by allowing on the one hand to remove visual defects in screwing such as those known under the name of " tears of paper "and on the other hand the consequences that these defects can have for the finish of the exposed face. It should be noted that if the invention finds a preferred application for fixing construction panels such as plasterboard, it applies in a nonlimiting manner to any type of construction panel.
L'invention s'étend également à un dispositif de vissage d'une vis de fixation dans un panneau de construction, caractérisé en ce qu'il comprend un outil de vissage tel que précédemment décrit. The invention also extends to a device for screwing a fixing screw into a construction panel, characterized in that it comprises a screwing tool as described above.
L’invention couvre aussi un outil portatif à commande manuelle qui comprend un outil de vissage tel que décrit dans le présent document. Il peut par exemple s’agir d’une visseuse, par exemple sans fil. The invention also covers a portable tool with manual control which comprises a screwing tool as described in this document. It can for example be a screwdriver, for example cordless.
Selon un autre exemple, l’invention vise un robot de vissage qui comprend un outil de vissage tel que décrit dans le présent document. Un tel robot de vissage comporte au moins un socle configuré pour être solidaire d’un sol et est équipé d'un bras à une extrémité duquel est placé l'outil de vissage selon l'invention, les mouvements de l'outil de vissage et du bras qui le porte étant gouvernés par une unité électronique de pilotage. Un tel robot de vissage est un moyen industriel lourd utilisé dans le cadre d’opérations de vissage répétitives. According to another example, the invention relates to a screwing robot which comprises a screwing tool as described in this document. Such a screwing robot comprises at least one base configured to be fixed to a floor and is equipped with an arm at one end of which is placed the screwing tool according to the invention, the movements of the tool of screwing and of the arm which carries it being governed by an electronic control unit. Such a screwing robot is a heavy industrial means used in the context of repetitive screwing operations.
L'invention s'étend enfin à un dispositif automatisé configuré pour se déplacer en appui sur un panneau de construction, le dispositif automatisé comprenant un châssis porteur d'un dispositif de vissage tel que précédemment présenté, le dispositif automatisé étant configuré pour réaliser au moins une opération de fixation du panneau de construction sur un support de celui-ci, le dispositif automatisé comprenant au moins un organe de maintien du dispositif automatisé contre le panneau de construction et au moins un moyen de mise en mouvement du dispositif automatisé le long du panneau de construction. The invention finally extends to an automated device configured to move in abutment on a construction panel, the automated device comprising a frame carrying a screwing device as previously presented, the automated device being configured to produce at least an operation for fixing the building panel to a support thereof, the automated device comprising at least one member for holding the automated device against the building panel and at least one means for setting the automated device in motion along the panel of construction.
Il faut comprendre ici que le dispositif automatisé selon l'invention se déplace contre la face exposée du panneau de construction, et que, dans ce déplacement, le dispositif automatisé selon l'invention reste en contact permanent avec cette face, quelle que soit l'orientation spatiale du panneau de construction. Ce contact permanent est assuré par l'organe de maintien qui peut prendre la forme d’un organe d'aspiration, ce dernier comprenant au moins un dispositif d'étanchéité et un plateau constitutif du châssis, qui délimitent une chambre de dépression. Une fois le dispositif automatisé plaqué contre le panneau de construction, la chambre de dépression est fermée par la face exposée de ce panneau contre laquelle le dispositif automatisé est placé, l'organe d'aspiration comprenant, par ailleurs, un moyen de mise en dépression débouchant dans la chambre de dépression précitée. It should be understood here that the automated device according to the invention moves against the exposed face of the construction panel, and that, in this displacement, the automated device according to the invention remains in permanent contact with this face, whatever the spatial orientation of the construction panel. This permanent contact is provided by the holding member which can take the form of a suction member, the latter comprising at least one sealing device and a plate constituting the chassis, which delimit a vacuum chamber. Once the automated device is pressed against the construction panel, the vacuum chamber is closed by the exposed face of this panel against which the automated device is placed, the suction member further comprising a means of depression opening into the aforementioned vacuum chamber.
Selon un exemple de réalisation de l'invention, le moyen de mise en mouvement du dispositif automatisé comprend un moteur de mise en mouvement, par exemple un moteur électrique alimenté en courant par un réseau domestique ou par un dispositif de stockage électrique embarqué sur le châssis. Ce dernier comporte avantageusement un ou plusieurs moyens de déplacement tels que, à titre d'exemples non limitatifs, des roues, des chenilles ou des pattes. D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement à la lecture de la description donnée ci-après à titre indicatif, en relation avec les dessins suivants, dans lesquels : According to an exemplary embodiment of the invention, the means for setting in motion the automated device comprises a setting in motion motor, for example an electric motor supplied with current by a home network or by an electrical storage device on board the chassis. .

Il faut tout d’abord noter que si les figures exposent l’invention de manière détaillée pour sa mise en œuvre, ces figures peuvent bien entendu servir à mieux définir l’invention, le cas échéant. Il est également à noter que les mêmes éléments sont désignés par les mêmes repères sur l'ensemble des figures. It should first of all be noted that if the figures show the invention in detail for its implementation, these figures can of course be used to better define the invention, if necessary. It should also be noted that the same elements are designated by the same references on all of the figures.
En référence à la figure 1, un outil de vissage 100 selon l’invention comprend un embout de vissage 1 qui s'étend selon une direction principale d'allongement parallèle à un axe de révolution X de l’outil de vissage 100. With reference to FIG. 1, a screwing tool 100 according to the invention comprises a screwing tip 1 which extends in a main direction of elongation parallel to an axis of revolution X of the screwing tool 100.
A l'une de ses extrémités 15 selon sa direction longitudinale, l’embout de vissage 1 est relié à une queue 16 de l'outil de vissage, coaxiale avec l’embout de vissage 1. Une telle queue 16 est la partie de l’outil de vissage 100 qui est destinée à se loger dans un mandrin destiné à entraîner en rotation de l’outil de vissage 100. A son extrémité distalelO, opposé à la queue 16 selon sa direction longitudinale, l’embout de vissage 1 présente une portion 11 configurée pour coopérer avec une tête d'une vis de fixation, non représentée sur la figure 1. At one of its ends 15 in its longitudinal direction, the screwing tip 1 is connected to a shank 16 of the screwing tool, coaxial with the screwing tip 1. Such a shank 16 is the part of the screwing tool 100 which is intended to be housed in a mandrel intended to drive the screwing tool 100 in rotation. At its distalelO end, opposite the shank 16 in its longitudinal direction, the screwing tip 1 has a portion 11 configured to cooperate with a head of a fixing screw, not shown in FIG. 1.
Selon l'exemple illustré par la figure 1, la portion 11 agencée à l'extrémité distale 10 de l’embout de vissage 1 est une forme mâle dont une section droite, selon un plan perpendiculaire à l'axe de révolution X, présente sensiblement la forme d'une croix. En d'autres termes, l'outil de vissage 100 est un outil de vissage cruciforme. Bien entendu, la forme de cette section droite n’est donnée qu’à titre d’exemple, et il pourrait également s’agir d’une section droite plate, hexagonale, étoile, etc... According to the example illustrated in FIG. 1, the portion 11 arranged at the distal end 10 of the screwing bit 1 is a male shape of which a cross section, along a plane perpendicular to the axis of revolution X, has substantially the shape of a cross. In other words, the screwing tool 100 is a cruciform screwing tool. Of course, the shape of this cross section is given only as an example, and it could also be a flat cross section, hexagonal, star, etc.
Selon cet exemple, la portion 11 est évasée selon la direction longitudinale de l’embout de vissage 1, de l'extrémité distale 10 de l’embout de vissage 1 vers l'extrémité proximale 15 rattachée à la queue 16. Plus précisément, la portion 11 présente des dimensions, mesurées perpendiculairement à l'axe de révolution X, qui augmentent le long de la direction longitudinale à partir de l'extrémité distale 10 de l’embout de vissage 1. Mesurée le long de l’axe de révolution X, la portion 11 s’étend sur une longueur illustrée par la référence DI sur la figure 1, le bout de cette portion 11 conique étant illustrée par un arc en pointillés. According to this example, the portion 11 is flared in the longitudinal direction of the screwing tip 1, from the distal end 10 of the screwing tip 1 towards the proximal end 15 attached to the tail 16. More precisely, the portion 11 has dimensions, measured perpendicular to the axis of revolution X, which increase along the longitudinal direction from the distal end 10 of the screwdriver bit 1. Measured along the axis of revolution X , the portion 11 extends over a length illustrated by the reference DI in FIG. 1, the end of this conical portion 11 being illustrated by a dotted arc.
D'une manière plus générale, la portion 11 de l’embout de vissage 1 présente une forme et des dimensions configurées pour réaliser une coopération de l’embout de vissage 1 avec une vis de fixation. More generally, the portion 11 of the screwing bit 1 has a shape and dimensions configured to achieve cooperation of the screwing bit 1 with a fixing screw.
Selon l’invention, l’outil de vissage 100 porte un moyen d'abrasion 2, par exemple en étant agencé coaxialement avec l’embout de vissage 1, autour de ce dernier. According to the invention, the screwing tool 100 carries an abrasion means 2, for example by being arranged coaxially with the screwing tip 1, around the latter.
Selon l'exemple illustré par la figure 1, le moyen d'abrasion 2 présente une forme sensiblement cylindrique dont l'axe de révolution est confondu avec l'axe de révolution X de l’embout de vissage 1, et dont la direction principale d'allongement est parallèle à l'axe de révolution X précité. Cette direction principale d'allongement sera, dans ce qui suit, désignée comme direction longitudinale du moyen d'abrasion 2. According to the example illustrated in FIG. 1, the abrasion means 2 has a substantially cylindrical shape whose axis of revolution coincides with the axis of revolution X of the screwing bit 1, and whose main direction d elongation is parallel to the aforementioned axis of revolution X. This main direction of elongation will, in what follows, be designated as the longitudinal direction of the abrasion means 2.
Comme le montre la figure 1, le moyen d'abrasion 2 est inséré autour de l’embout de vissage 1, et il présente, notamment à son extrémité longitudinale la plus proche de l'extrémité distale 10 de l’embout de vissage 1, une surface de frottement 20, sensiblement plane, perpendiculaire à l'axe de révolution X précédemment défini. As shown in Figure 1, the abrasion means 2 is inserted around the tip screw 1, and it has, in particular at its longitudinal end closest to the distal end 10 of the screw tip 1, a friction surface 20, substantially planar, perpendicular to the axis of revolution X previously defined.
Selon l'invention, le moyen d'abrasion 2 est mécaniquement lié à l’embout de vissage 1, de telle manière que, lorsque l’embout de vissage 1 est entraîné en rotation autour de son axe de révolution X, le moyen d'abrasion 2 est simultanément entraîné en rotation autour de ce même axe. Selon différents exemples, la liaison mécanique entre le moyen d'abrasion 2 et l’embout de vissage 1 peut être réalisée par insertion en force du moyen d'abrasion 2 autour de l’embout de vissage 1, par collage d'une surface intérieure du moyen d'abrasion sur une surface extérieure de l’embout de vissage, ou par réalisation de formes complémentaires sur une surface intérieure du moyen d'abrasion 2 et sur une surface extérieure de l’embout de vissage 1, de telle formes complémentaires étant configurées, par exemple, pour s'emboîter les unes dans les autres. According to the invention, the abrasion means 2 is mechanically linked to the screwing tip 1, so that, when the screwing tip 1 is rotated around its axis of revolution X, the means of abrasion 2 is simultaneously driven in rotation about this same axis. According to various examples, the mechanical connection between the abrasion means 2 and the screwing tip 1 can be achieved by forcefully inserting the abrasion means 2 around the screwing tip 1, by bonding an inner surface of the abrading means on an external surface of the screw-in nozzle, or by making complementary shapes on an internal surface of the abrading means 2 and on an external surface of the screw-in nipple 1, such complementary forms being configured, for example, to fit into each other.
Le moyen d’abrasion 2 peut être rendu solidaire de l’embout de vissage 1 d’une manière qui le rend indémontable sans endommager le moyen d’abrasion et/ou l’embout de vissage. De manière alternative, le moyen d'abrasion 2 est lié mécaniquement à l’embout de vissage 1 de manière démontable, manuellement ou à l'aide d'un outillage approprié, pour désolidariser le moyen d’abrasion 2 de l’embout de vissage 1. Le moyen d'abrasion 2 forme ainsi une pièce d'usure pouvant être remplacée sans qu'il soit nécessaire de remplacer l'ensemble de l'outil de vissage 100. The abrasion means 2 can be made integral with the screwing bit 1 in a manner which makes it non-removable without damaging the abrasion means and / or the screwing bit. Alternatively, the abrasion means 2 is mechanically linked to the screwing tip 1 in a removable manner, manually or using an appropriate tool, to separate the abrasion means 2 from the screwing tip 1. The abrasion means 2 thus forms a wear part which can be replaced without the need to replace the entire screwing tool 100.
Comme le montre la figure 1, la forme mâle agencée à l'extrémité distale 10 de l’embout de vissage 1 émerge, selon la direction longitudinale précédemment définie, du moyen d'abrasion 2. Plus précisément, une distance D, mesurée selon la direction de l'axe de révolution X précédemment défini entre l'extrémité distale 10 de l’embout de vissage 1 et un plan dans lequel s’inscrit la surface de frottement 20 du moyen d’abrasion 2, est strictement supérieure à zéro. Cette distance D est par ailleurs inférieure à la dimension DI précédemment définie, de sorte à garantir que la surface de frottement 20 vienne en appui sur le panneau de construction. D'une manière plus générale, la distance D précitée est inférieure à une longueur, mesurée selon la direction de l'axe de révolution X, de la partie de l’embout de vissage 1 configurée pour coopérer avec une tête d'une vis de fixation. As shown in FIG. 1, the male form arranged at the distal end 10 of the screwing tip 1 emerges, in the longitudinal direction previously defined, from the abrasion means 2. More precisely, a distance D, measured according to the direction of the axis of revolution X previously defined between the distal end 10 of the screwing tip 1 and a plane in which the friction surface 20 of the abrasion means 2 is inscribed, is strictly greater than zero. This distance D is also less than the dimension DI previously defined, so as to guarantee that the friction surface 20 comes to bear on the construction panel. More generally, the aforementioned distance D is less than a length, measured in the direction of the axis of revolution X, of the part of the screwing bit 1 configured to cooperate with a head of a fixing screw.
La figure 2 est une vue schématique en coupe, selon un plan contenant l'axe de révolution X, d'un premier mode de réalisation d'un outil de vissage 100 selon l'invention et d'une vis de fixation 3 avec laquelle l'outil de vissage 100 est configuré pour coopérer afin de réaliser la fixation d'un panneau de construction 4 sur un support 5. FIG. 2 is a schematic sectional view, along a plane containing the axis of revolution X, of a first embodiment of a screwing tool 100 according to the invention and of a fixing screw 3 with which the the screwing tool 100 is configured to cooperate in order to attach a construction panel 4 to a support 5.
En référence à cette figure, un panneau de construction 4 comprend une première face principale 40 et une deuxième face principale 41 , sensiblement parallèles entre elles et séparées l’une de l’autre par une épaisseur 42, faible devant les dimensions des faces principales 40, 41. With reference to this figure, a construction panel 4 comprises a first main face 40 and a second main face 41, substantially parallel to each other and separated from each other by a thickness 42, small compared to the dimensions of the main faces 40 , 41.
La première face principale 40 est ici la face exposée du panneau de construction 4, destinée à rester visible lorsque le panneau de construction 4 est fixé sur le support 5. The first main face 40 is here the exposed face of the construction panel 4, intended to remain visible when the construction panel 4 is fixed to the support 5.
Selon différents modes de réalisation, le support 5 peut être métallique, synthétique, en bois, ou il peut être formé d'un matériau composite par exemple à base de fragments de bois et d'une résine. Quel que soit le matériau qui le constitue, le support 5 est un élément rigide soit rendu solidaire d'une paroi d'un bâtiment, par exemple par des vis, des boulons, des agrafes, des suspentes ou collé sur celle-ci, soit indépendant de cette paroi de bâtiment pour former, par exemple, une cloison séparatrice entre deux pièces. According to different embodiments, the support 5 can be metallic, synthetic, wooden, or it can be formed from a composite material, for example based on wood fragments and a resin. Whatever the material which constitutes it, the support 5 is a rigid element either made integral with a wall of a building, for example by screws, bolts, staples, hangers or glued to it, or independent of this building wall to form, for example, a separating partition between two rooms.
En référence à la figure 2, le panneau de construction 4 est fixé sur le support 5 par au moins une vis de fixation 3, préférentiellement par un ensemble de vis de fixation 3. Une vis de fixation 3 comprend une partie filetée 30, qui s'étend principalement selon la direction d'un axe principal de révolution 300, et une tête 31. A l'une de ses extrémités selon la direction de l'axe de révolution 300, la partie filetée 30 comprend une pointe conique 32, coaxiale avec l'axe de révolution 300 de la vis de fixation 3. With reference to FIG. 2, the construction panel 4 is fixed to the support 5 by at least one fixing screw 3, preferably by a set of fixing screws 3. A fixing screw 3 comprises a threaded part 30, which s 'extends mainly in the direction of a main axis of revolution 300, and a head 31. At one of its ends in the direction of the axis of revolution 300, the threaded part 30 comprises a conical tip 32, coaxial with the axis of revolution 300 of the fixing screw 3.
La tête 31 de la vis de fixation 3 présente une forme conique, dont l'axe est confondu avec l'axe de révolution 300 de la vis de fixation 3. La tête 31 de la vis de fixation 3 présente une surface sensiblement plane 33, désignée dans ce qui suit comme surface supérieure 33 de la vis de fixation 3. La partie conique de la tête 31 de la vis de fixation 3 présente une surface 35 qui joint entre elles la partie filetée 30 et la surface supérieure 33 de la tête 31 de la vis de fixation 3. The head 31 of the fixing screw 3 has a conical shape, the axis of which coincides with the axis of revolution 300 of the fixing screw 3. The head 31 of the fixing screw 3 has a substantially planar surface 33, designated in the following as the upper surface 33 of the fixing screw 3. The conical part of the head 31 of the fixing screw 3 has a surface 35 which joins together the threaded part 30 and the surface upper 33 of the head 31 of the fixing screw 3.
La surface supérieure 33 présente sensiblement la forme d'un disque dont le diamètre est supérieur au diamètre de la partie filetée 30. Avantageusement, la surface supérieure 33 comporte une empreinte femelle 34 avec laquelle l'outil de vissage 100 selon l'invention coopère. Plus précisément, la portion 1 1 de l’embout de vissage 1 coopère avec la forme 34 agencée dans la tête 31 de la vis de fixation 3, de telle manière que, lors du vissage de la vis de fixation 3, l’embout de vissage 1, entraînée en rotation autour de son axe de révolution X, entraîne à son tour la vis de fixation 3 en rotation autour de son axe de rotation 300. Grâce au filetage de la partie filetée 30, la vis de fixation 3 progresse alors en translation au sein du matériau dans lequel elle est insérée. Comme le montre la figure 2, lors du vissage de la vis de fixation 3, l'axe de rotation 300 de celle-ci et l'axe de révolution X de l’embout de vissage 1 sont sensiblement confondus. The upper surface 33 has substantially the shape of a disc the diameter of which is greater than the diameter of the threaded portion 30. Advantageously, the upper surface 33 includes a female imprint 34 with which the screwing tool 100 according to the invention cooperates. More specifically, the portion 1 1 of the screwing tip 1 cooperates with the shape 34 arranged in the head 31 of the fixing screw 3, so that, during the screwing of the fixing screw 3, the end piece screw 1, driven in rotation about its axis of revolution X, in turn drives the fixing screw 3 in rotation about its axis of rotation 300. Thanks to the threading of the threaded part 30, the fixing screw 3 then progresses translation within the material in which it is inserted. As shown in FIG. 2, during the screwing of the fixing screw 3, the axis of rotation 300 of the latter and the axis of revolution X of the screwing bit 1 are substantially combined.
Selon l'exemple de réalisation illustré par la figure 2, le moyen d'abrasion 2 comprend une pièce d'abrasion 21 réalisée dans un matériau abrasif, sensiblement cylindrique et centrée sur l'axe de révolution X de l’embout de vissage 1. Selon différents exemples de réalisation, le matériau abrasif constitutif de la pièce d'abrasion 21 peut être un matériau élastomère tel qu'une gomme, ou un matériau composite dans lequel sont insérés des grains de céramique ou de silice, ou encore un matériau sur lequel est rapportée une couche d'un matériau abrasif. Dans ce dernier cas, la couche de matériau abrasif est avantageusement rapportée sur la surface de frottement 20 sensiblement annulaire de la pièce d’abrasion 21. Selon le mode de réalisation plus particulièrement illustré par la figure 2, la pièce d'abrasion 21 précitée est avantageusement une pièce massive et monobloc. According to the exemplary embodiment illustrated by FIG. 2, the abrasion means 2 comprises an abrasion part 21 made of an abrasive material, substantially cylindrical and centered on the axis of revolution X of the screwing bit 1. According to different exemplary embodiments, the abrasive material constituting the abrasion piece 21 can be an elastomeric material such as a rubber, or a composite material in which grains of ceramic or silica are inserted, or else a material on which a layer of abrasive material is added. In the latter case, the layer of abrasive material is advantageously attached to the substantially annular friction surface 20 of the abrasion piece 21. According to the embodiment more particularly illustrated in FIG. 2, the abraded piece 21 is advantageously a massive and monobloc piece.
Le moyen d’abrasion 2 peut également comprend une pluralité de pièces d’abrasion qui prennent par exemple la forme de secteurs angulaires distincts réparties autour de l’embout de vissage 1. Comme le montre la figure 2, la pièce d'abrasion 21 est agencée de telle manière que sa surface de frottement 20 se trouve en contact avec la face exposée 40 du panneau de construction 4, lorsque la surface supérieure 33 de la tête de la vis de fixation 3 est coplanaire avec la face exposée 40 du panneau de construction 4. Plus précisément, la distance D représentée sur la figure 1 , mesurée entre la surface de frottement 20 de la pièce d'abrasion 21 et l'extrémité distale 10 de l’embout de vissage 1, est définie de telle manière que la surface de frottement 20 se trouve au contact de la face exposée 40 du panneau de construction 4 quand la surface supérieure 33 de la vis de fixation 3 est sensiblement coplanaire avec la face exposée 40 du panneau de construction 4. The abrasion means 2 can also comprise a plurality of abrasion pieces which take, for example, the form of distinct angular sectors distributed around the screwing bit 1. As shown in FIG. 2, the abrasion piece 21 is arranged in such a way that its friction surface 20 comes into contact with the exposed face 40 of the construction panel 4, when the upper surface 33 of the head of the screw fixing 3 is coplanar with the exposed face 40 of the construction panel 4. More specifically, the distance D shown in FIG. 1, measured between the friction surface 20 of the abrasion piece 21 and the distal end 10 of l screwing bit 1, is defined such that the friction surface 20 is in contact with the exposed face 40 of the construction panel 4 when the upper surface 33 of the fixing screw 3 is substantially coplanar with the exposed face 40 of the construction panel 4.
De manière avantageuse, la pièce d’abrasion 21 peut être souple, de manière à se comprimer quand la surface de frottement 20 prend appui sur la face exposée 40, alors que la vis de fixation 3 progresse dans le support 5. On garantit ainsi le maintien d’une bonne prise entre l’embout de vissage 1 et la tête 31 de la vis de fixation 3, sans que le moyen d’abrasion 2 ne nuise à cette prise. Advantageously, the abrasion part 21 can be flexible, so as to compress when the friction surface 20 bears on the exposed face 40, while the fixing screw 3 progresses in the support 5. This guarantees the maintaining a good grip between the screwing tip 1 and the head 31 of the fixing screw 3, without the abrasion means 2 adversely affecting this grip.
La pièce d'abrasion 21 étant simultanément entraînée en rotation par la rotation de l’embout de vissage 1 , il résulte de ce qui précède que la surface de frottement 20 frotte alors contre la face exposée 40 du panneau de construction 4, réalisant ainsi l'abrasion de la face exposée 40 autour de la tête 31 de la vis de fixation 3. La surface de frottement 20 précédemment définie constitue ainsi une surface active, notamment de section annulaire, de la pièce d'abrasion 21 et, plus généralement, du moyen d'abrasion 2. The abrasion part 21 being simultaneously driven in rotation by the rotation of the screwing tip 1, it follows from the above that the friction surface 20 then rubs against the exposed face 40 of the construction panel 4, thus realizing the abrasion of the exposed face 40 around the head 31 of the fixing screw 3. The friction surface 20 previously defined thus constitutes an active surface, in particular of annular section, of the abrasion part 21 and, more generally, of the abrasion medium 2.
Il résulte de ce qui précède qu’une zone annulaire 410 entre la surface de frottement 20 de la pièce d'abrasion 21 et la face exposée 40 du panneau de construction 4 a la forme d'un anneau centré sur l'axe de rotation X de l'outil de vissage 100, autour de la surface supérieure 33 de la tête 31 de la vis de fixation 3. It follows from the above that an annular zone 410 between the friction surface 20 of the abrasion piece 21 and the exposed face 40 of the construction panel 4 has the shape of a ring centered on the axis of rotation X of the screwing tool 100, around the upper surface 33 of the head 31 of the fixing screw 3.
L'abrasion réalisée par la surface de frottement 20 sur la face exposée 40 du panneau de construction 4 a pour résultat l'obtention de la zone annulaire 410 sensiblement plane et lisse, exempte de toutes particules provenant du matériau du panneau de construction 4, par exemple du carton, provenant de la face exposée 40 de ce panneau de construction 4. The abrasion produced by the friction surface 20 on the exposed face 40 of the construction panel 4 results in the obtaining of the annular zone 410 which is substantially flat and smooth, free of any particles originating from the material of the construction panel 4, by example of the cardboard, coming from the exposed face 40 of this construction panel 4.
Selon l'exemple illustré par la figure 2, les dimensions de la pièce d'abrasion 21 sont définies de telle manière que la surface de frottement 20 présente au moins une dimension mesurée dans le plan de la surface de frottement 20 qui est strictement supérieure à une dimension de la surface supérieure 33 de la tête 31 de la vis de fixation 3, mesurée dans un plan parallèle au plan de la surface de frottement 20 et passant par la surface supérieure 33. Ces dimensions sont notamment des diamètres. According to the example illustrated in FIG. 2, the dimensions of the abrasion part 21 are defined in such a way that the friction surface 20 has at least one dimension measured in the plane of the friction surface 20 which is strictly greater than a dimension of the upper surface 33 of the head 31 of the fixing screw 3, measured in a plane parallel to the plane of the friction surface 20 and passing through the upper surface 33. These dimensions are in particular diameters.
Selon une variante du premier mode de réalisation plus particulièrement illustrée par la figure 3, le moyen d'abrasion 2 comporte une cloche 25 et un organe élastique 22. On retrouve sur la figure 3 l’embout de vissage 1, le moyen d’abrasion 2 et sa pièce d'abrasion 21, ainsi que la vis de fixation 3, le panneau de construction 4, le support 5. L’organe élastique 22 et/ou la cloche 25 sont également compatibles pour opérer avec une pluralité de pièces d’abrasion, que le moyen d’abrasion en comprend plusieurs. According to a variant of the first embodiment more particularly illustrated in FIG. 3, the abrasion means 2 comprises a bell 25 and an elastic member 22. We find in FIG. 3 the screwing bit 1, the abrasion means 2 and its abrasion piece 21, as well as the fixing screw 3, the construction panel 4, the support 5. The elastic member 22 and / or the bell 25 are also compatible for operating with a plurality of pieces of abrasion, that the means of abrasion includes several.
La cloche 25 est sensiblement cylindrique, d'axe confondu avec l'axe de révolution X de l’embout de vissage 1. La cloche 25 peut également présenter toute autre forme susceptible de recevoir la pièce d’abrasion 21 sans entraver son déplacement le long de l’embout de vissage. Cette cloche 25 est formée d'un fond 26 sensiblement perpendiculaire à l'axe de rotation X, à partir duquel s'étend une bague 27 sensiblement cylindrique, parallèlement à l'axe de révolution X de l’embout de vissage 1. La cloche 25 délimite ainsi une cavité 250, ouverte à son extrémité opposée au fond 26 selon la direction de l'axe de révolution X. The bell 25 is substantially cylindrical, with its axis coinciding with the axis of revolution X of the screwing tip 1. The bell 25 can also have any other shape capable of receiving the abrasion part 21 without impeding its movement along of the screwdriver bit. This bell 25 is formed by a bottom 26 substantially perpendicular to the axis of rotation X, from which extends a substantially cylindrical ring 27, parallel to the axis of revolution X of the screwing bit 1. The bell 25 thus delimits a cavity 250, open at its end opposite to the bottom 26 in the direction of the axis of revolution X.
On notera que l’invention couvre un embout de vissage 1 qui serait pourvu du fond 26 et dépourvu de la bague 27 exposée ci-dessus. It will be noted that the invention covers a screwdriver bit 1 which would be provided with the bottom 26 and devoid of the ring 27 exposed above.
Selon l'exemple de réalisation illustré par la figure 3, le fond 26 de la cloche 25 est solidaire de l’embout de vissage 1, de telle manière que la cloche 25 est entraînée en rotation, autour de l'axe de révolution X, par la rotation de l’embout de vissage 1. According to the example of embodiment illustrated by FIG. 3, the bottom 26 of the bell 25 is integral with the screwing tip 1, so that the bell 25 is rotated around the axis of revolution X, by the rotation of the screwing bit 1.
Comme le montre plus précisément la figure 3, l’organe élastique 22 est logé au sein de la cavité 250, et comprimé entre la pièce d'abrasion 21 et le fond 26 de la cloche 25. Selon l’exemple de la figure 3, l’organe élastique 22 est un ressort, mais il pourrait aussi s’agir d’une mousse ou d’un empilement de clinquants, et d’une manière générale de tout moyen capable de se comprimer et d’exercer une force de rappel. As shown more precisely in Figure 3, the elastic member 22 is housed within of the cavity 250, and compressed between the abrasion piece 21 and the bottom 26 of the bell 25. According to the example in FIG. 3, the elastic member 22 is a spring, but it could also be a foam or a stack of foils, and generally any means capable of compressing and exerting a restoring force.
L’organe élastique 22, par exemple solidaire du fond 26, sollicite la pièce d’abrasionThe elastic member 22, for example integral with the bottom 26, urges the abrasion part
21 en direction de l’extrémité distale 10 de l’embout de vissage 1. Lorsque la pièce d’abrasion 21 entre en contact avec la face exposée 40 du panneau de construction 4, l’organe élastique 22 se retrouve comprimé, et sa force de poussée maintient la pièce d’abrasion 21 contre le panneau de construction 4. On notera que la longueur totale au repos de l’organe élastique 22 et la longueur totale de la pièce d’abrasion 21, mesurées toutes deux le long de l’axe de révolution X, sont choisis de sorte que l’organe élastique ne repousse pas totalement la pièce d’abrasion 21 hors de la cloche 25. 21 in the direction of the distal end 10 of the screwing tip 1. When the abrasion part 21 comes into contact with the exposed face 40 of the construction panel 4, the elastic member 22 finds itself compressed, and its force thrust holds the abrasion piece 21 against the building panel 4. It will be noted that the total length at rest of the elastic member 22 and the total length of the abrasion piece 21, both measured along the axis of revolution X, are chosen so that the elastic member does not completely push the abrasion part 21 out of the bell 25.
La paroi formant le fond 26 de la cloche 25 constitue ainsi une butée de l’organe élastique 22. L’organe élastique 22 est comprimé entre le fond 26 de la cloche 25 et une face supérieure 23 de la pièce d'abrasion 21, opposée à la surface de frottement 20 de cette dernière, selon sa direction longitudinale. Une hauteur de la bague 27, mesurée le long de l’axe de révolution X de l’embout de vissage 1, est définie de telle manière que l’organe élastique 22 est reçu en totalité dans la cavité 250, et qu'une partie au moins de la pièce d'abrasion 21 est également reçue dans la cavité 250. En d'autres termes, et comme le montre la figure 3, la cloche 25 forme un capuchon de la pièce d'abrasion 21 et de l’organe élastique 22, capuchon dans lequel l’organe élastique 22 est comprimé entre le fond 26 de la cloche 25 et la pièce d'abrasion 21. The wall forming the bottom 26 of the bell 25 thus constitutes a stop for the elastic member 22. The elastic member 22 is compressed between the bottom 26 of the bell 25 and an upper face 23 of the abrasion piece 21, opposite to the friction surface 20 of the latter, in its longitudinal direction. A height of the ring 27, measured along the axis of revolution X of the screwing piece 1, is defined in such a way that the elastic member 22 is received entirely in the cavity 250, and that part at least the abrasion piece 21 is also received in the cavity 250. In other words, and as shown in FIG. 3, the bell 25 forms a cap for the abrasion piece 21 and the elastic member 22, cap in which the elastic member 22 is compressed between the bottom 26 of the bell 25 and the abrasion piece 21.
Sous l'effet de l'usure, l'épaisseur de la pièce d'abrasion 21, mesurée selon la direction de l'axe de révolution X de l’embout de vissage 1, diminue. L’organe élastiqueUnder the effect of wear, the thickness of the abrasion piece 21, measured along the direction of the axis of revolution X of the screwdriver bit 1, decreases. The elastic organ
22 se détend alors en exerçant sur la surface supérieure 23 de la pièce d’abrasion 21 un effort dirigé selon l'axe de révolution X de l’embout de vissage 1, en direction de l'extrémité distale 10 de l’embout de vissage 1, maintenant ainsi le plaquage de la surface de frottement 20 de la pièce d'abrasion 21 contre la face exposée 40 du panneau de construction 4. En d'autres termes, l’organe élastique 22 permet de compenser l'usure de la pièce d'abrasion 21 et de maintenir cette dernière constamment plaquée contre la face exposée 40 du panneau de construction 4. 22 then relaxes by exerting on the upper surface 23 of the abrasion piece 21 a force directed along the axis of revolution X of the screwing tip 1, towards the distal end 10 of the screwing tip 1, thus maintaining the plating of the friction surface 20 of the abrasion part 21 against the exposed face 40 of the panel construction 4. In other words, the elastic member 22 makes it possible to compensate for the wear of the abrasion part 21 and to keep the latter constantly pressed against the exposed face 40 of the construction panel 4.
La figure 4 présente un deuxième mode de réalisation du moyen d'abrasion 2 selon l’invention. Selon ce deuxième mode de réalisation, le moyen d'abrasion 2 comprend une brosse 28 coaxiale avec l'axe de révolution X de l’embout de vissage 1. Cette brosse 28 comprend une base 285 dont sont issus des poils 280 dirigés selon une direction sensiblement parallèle à l'axe de révolution X précité. FIG. 4 shows a second embodiment of the abrasion means 2 according to the invention. According to this second embodiment, the abrasion means 2 comprises a brush 28 coaxial with the axis of revolution X of the screwing tip 1. This brush 28 comprises a base 285 from which hairs 280 are directed in a direction substantially parallel to the aforementioned axis of revolution X.
Selon cet exemple de réalisation, les poils 280 de la brosse 28 se présentent sous la forme de tiges flexibles sensiblement parallèles entre elles et dont la direction principale d'extension commune est sensiblement parallèle à l'axe de révolution X de l’embout de vissage 1. Comme le montre la figure 4, les poils 280 de la brosse 28 sont solidaires de la base 285, cette dernière s’étendant dans un plan sensiblement perpendiculaire à l'axe de révolution X de l’embout de vissage 1. According to this exemplary embodiment, the bristles 280 of the brush 28 are in the form of flexible rods substantially parallel to each other and whose main direction of common extension is substantially parallel to the axis of revolution X of the screwdriver bit. 1. As shown in FIG. 4, the bristles 280 of the brush 28 are integral with the base 285, the latter extending in a plane substantially perpendicular to the axis of revolution X of the screwing bit 1.
Chaque poil 280 de la brosse 28 comporte donc ici, selon sa direction principale d'extension, une extrémité par laquelle il est rattaché à la base 285 précitée, et une extrémité libre située, selon la direction longitudinale de l'axe de révolution X de l’embout de vissage 1, la plus proche de l'extrémité distale 10 de l’embout de vissage 1. La surface de frottement 20 du moyen d'abrasion 2 est donc, dans ce cas, définie par l'ensemble des extrémités libres des poils 280 de la brosse 28. Selon ce mode de réalisation, la surface de frottement 20, ou surface active du moyen d'abrasion 2, n'est donc pas ici une surface continue mais une surface constituée par la somme des extrémités des poils 280. Il résulte de cette configuration un avantage tel qu’il permet de faciliter l'évacuation, en cours d'abrasion, des particules et poussières résultant de l'abrasion réalisée sur une face exposée 40 d'un panneau de construction 4. Each bristle 280 of the brush 28 therefore comprises here, in its main direction of extension, an end by which it is attached to the aforementioned base 285, and a free end situated, in the longitudinal direction of the axis of revolution X of the screwing tip 1, closest to the distal end 10 of the screwing tip 1. The friction surface 20 of the abrasion means 2 is therefore, in this case, defined by all of the free ends bristles 280 of the brush 28. According to this embodiment, the friction surface 20, or active surface of the abrasion means 2, is therefore not here a continuous surface but a surface formed by the sum of the ends of the bristles 280. This configuration results in an advantage such that it makes it possible to facilitate the evacuation, during abrasion, of the particles and dust resulting from the abrasion produced on an exposed face 40 of a construction panel 4.
Comme le montre la figure 4, les poils 280 de la brosse 28 sont organisés dans un volume sensiblement cylindrique coaxial avec l'axe de révolution X de l’embout de vissage 1, la surface de frottement est donc également, comme dans les exemples précédemment décrits, sensiblement annulaire et centrée sur l'axe de révolution X de l’embout de vissageAs shown in FIG. 4, the bristles 280 of the brush 28 are organized in a substantially cylindrical volume coaxial with the axis of revolution X of the screwing bit 1, the friction surface is therefore also, as in the examples above described, substantially annular and centered on the axis of revolution X of the screwdriver bit
1. 1.
De manière similaire aux exemples précédemment évoqués, la base 285 est solidaire de l’embout de vissage 1, de telle manière que la brosse 28 est simultanément entraînée en rotation par une rotation de l’embout de vissage 1 autour de son axe de révolution X. Similarly to the examples mentioned above, the base 285 is integral with the screwing tip 1, so that the brush 28 is simultaneously driven in rotation by a rotation of the screwing tip 1 about its axis of revolution X .
Par ailleurs, les poils 280 de la brosse 28 sont agencés de telle manière que l'extrémité distale 10 de l’embout de vissage 1 s'étend, selon la direction longitudinale de l'axe de révolution X, au-delà de la surface de frottement 20 du moyen d'abrasion 2, c'est- à-dire au-delà des extrémités libres des poils 280 de la brosse 28. En d'autres termes, comme illustré par la figure 4, la distance D mesurée, selon la direction longitudinale de l'axe de révolution X, entre l'extrémité distale 10 de l’embout de vissage 1 et la surface de frottement 20 définie par l'extrémité libre des poils 280 de la brosse 28, est non nulle, et elle est inférieure à la dimension, mesurée selon la même direction, de la portion 11 de l’embout de vissage 1. Furthermore, the bristles 280 of the brush 28 are arranged in such a way that the distal end 10 of the screwing tip 1 extends, in the longitudinal direction of the axis of revolution X, beyond the surface friction 20 of the abrasion means 2, that is to say beyond the free ends of the bristles 280 of the brush 28. In other words, as illustrated by FIG. 4, the distance D measured, according to the longitudinal direction of the axis of revolution X, between the distal end 10 of the screwing tip 1 and the friction surface 20 defined by the free end of the bristles 280 of the brush 28, is not zero, and it is less than the dimension, measured in the same direction, of the portion 11 of the screwing bit 1.
Selon différents exemples, les poils 280 de la brosse 28 peuvent être réalisés dans un matériau synthétique ou dans un matériau métallique. D'une manière générale, le matériau formant les poils 280 de la brosse 28 est choisi pour autoriser une certaine flexibilité des poils 280, tout en présentant une dureté suffisante pour que le frottement de l'extrémité libre de ces derniers contre une face exposée 40 d'un panneau de construction permette d'obtenir l'abrasion recherchée. According to different examples, the bristles 280 of the brush 28 can be made from a synthetic material or from a metallic material. In general, the material forming the bristles 280 of the brush 28 is chosen to allow a certain flexibility of the bristles 280, while having sufficient hardness so that the friction of the free end of the latter against an exposed face 40 of a construction panel allows to obtain the desired abrasion.
La figure 5 illustre un outil portatif 500 à commande manuelle équipé d'un outil de vissage 100 selon l’un quelconque des modes de réalisation décrits aux figures 1 à 4. Un tel outil portatif 500 à commande manuelle comporte une tête de serrage 550 configurée pour recevoir l’outil de vissage 100. L’outil portatif 500 à commande manuelle tel qu'illustré par la figure 5 est avantageusement formé d'un corps 510 muni d'une poignée de préhension 520. L'outil portatif 500 comprend avantageusement un moteur, par exemple un moteur électrique 530 placé dans le corps 510 de l'outil portatif 500. Selon différents exemples de réalisation, le moteur électrique 530 peut être alimenté en courant par un réseau domestique ou il peut être alimenté en courant par un dispositif de stockage d’énergie électrique non représenté sur la figure 5, par exemple emboîté sur une partie du corps 510 de l'outil portatif 500. FIG. 5 illustrates a portable tool 500 with manual control equipped with a screwing tool 100 according to any of the embodiments described in FIGS. 1 to 4. Such a portable tool 500 with manual control comprises a tightening head 550 configured to receive the screwing tool 100. The portable tool 500 with manual control as illustrated in FIG. 5 is advantageously formed of a body 510 provided with a grip handle 520. The portable tool 500 advantageously comprises a motor, for example an electric motor 530 placed in the body 510 of the portable tool 500. According to different exemplary embodiments, the electric motor 530 can be supplied with current by a domestic network or it can be supplied with current by an electrical energy storage device not shown in FIG. 5, for example fitted onto a part of the body 510 of the portable tool 500.
Le moteur électrique 530 met en rotation l'outil de vissage 100 porté par la tête de serrage 550, autour d'un axe de révolution X de l'outil de vissage 100. Pour la fixation d'un panneau de construction 4 sur un support 5, l'outil portatif 500 est positionné de telle manière que l'axe de révolution X de l’outil de vissage 100 est sensiblement confondu avec l'axe de révolution d'une vis de fixation, non représentée sur la figure 5. L’embout de vissage de l'outil de vissage 100 porté par l'outil portatif 500 est alors engagé avec une empreinte, femelle ou mâle, réalisée dans la tête de la vis de fixation, puis entraînée en rotation par le moteur électrique 530, entraînant à son tour en rotation la vis de fixation 3. The electric motor 530 rotates the screwing tool 100 carried by the clamping head 550, around an axis of revolution X of the screwing tool 100. For fixing a construction panel 4 on a support 5, the portable tool 500 is positioned in such a way that the axis of revolution X of the screwing tool 100 is substantially coincident with the axis of revolution of a fixing screw, not shown in FIG. 5. L screwing end of the screwing tool 100 carried by the portable tool 500 is then engaged with an impression, female or male, made in the head of the fixing screw, then driven in rotation by the electric motor 530, driving in turn the fixing screw 3.
La figure 6 illustre un robot de vissage 600 qui fait usage d’un outil de vissage 100 selon l’un quelconque des modes de réalisation décrits aux figures 1 à 4. FIG. 6 illustrates a screwing robot 600 which makes use of a screwing tool 100 according to any of the embodiments described in FIGS. 1 to 4.
En référence à la figure 6, le robot de vissage 600 comporte au moins un socle 610 destiné à être rendu solidaire du sol, ainsi qu'un bras 620 équipé d'une tête de serrage 650 dans laquelle est inséré l’outil de vissage 100. De manière analogue à l'exemple illustré par la figure 5, la tête de serrage 650 est avantageusement configurée pour recevoir des outils de vissage 100 de formes différentes configurés pour coopérer avec différentes formes réalisées dans une tête d'une vis de fixation, non représentée sur la figure 6. With reference to FIG. 6, the screwing robot 600 comprises at least one base 610 intended to be made integral with the ground, as well as an arm 620 equipped with a clamping head 650 in which is inserted the screwing tool 100 Similarly to the example illustrated in FIG. 5, the clamping head 650 is advantageously configured to receive screwing tools 100 of different shapes configured to cooperate with different shapes made in a head of a fixing screw, not shown in Figure 6.
Les mouvements du robot de vissage 600 sont ici gouvernés par une unité électronique de pilotage 640 configurée notamment pour commander les mouvements du bras 620, ainsi que la mise en rotation de l'outil de vissage 100 par un moteur électrique 630 que la tête de serrage 650 comporte. The movements of the screwing robot 600 are here governed by an electronic control unit 640 configured in particular to control the movements of the arm 620, as well as the rotation of the screwing tool 100 by an electric motor 630 that the clamping head 650 includes.
La figure 7 illustre un dispositif automatisé 700 auquel s'étend l'invention, configuré pour se déplacer de manière autonome contre un panneau de construction afin de fixer le panneau de configuration considéré sur un support. En référence à la figure 7, le dispositif automatisé 700 selon l'invention comprend un châssis 701 qui présente une forme générale sensiblement rectangulaire s'étendant selon une direction principale d'allongement A, autrement appelée direction longitudinale du dispositif automatisé 700. En référence à cette direction principale d'allongement A, on définit une direction transversale B du dispositif automatisé 700, perpendiculaire à la direction principale d'allongement A, et une direction verticale C perpendiculaire au plan défini par la direction principale d’allongement A et par la direction transversale B précitées, de telle manière que les directions A, B, C forment un trièdre direct. En référence à ce trièdre direct A, B, C, le châssis 701 s'étend sensiblement principalement dans un plan défini par la direction longitudinale A et par la direction transversale B. FIG. 7 illustrates an automated device 700 to which the invention extends, configured to move autonomously against a construction panel in order to fix the configuration panel considered on a support. With reference to FIG. 7, the automated device 700 according to the invention comprises a frame 701 which has a generally substantially rectangular shape extending in a main direction of elongation A, otherwise called longitudinal direction of the automated device 700. With reference to this main direction of elongation A, a transverse direction B of the automated device 700 is defined, perpendicular to the main direction of elongation A, and a vertical direction C perpendicular to the plane defined by the main direction of elongation A and by the direction transverse B above, so that the directions A, B, C form a direct trihedron. With reference to this direct trihedron A, B, C, the frame 701 extends substantially mainly in a plane defined by the longitudinal direction A and by the transverse direction B.
Tel qu’illustré sur la figure 7, le châssis 701 du dispositif automatisé 700 comprend une partie centrale 710 porteuse notamment d'un dispositif de vissage 750 configuré pour recevoir l’outil de vissage 100, et deux plateformes 711 agencées de part et d’autre de la partie centrale 710. Autrement dit, le dispositif automatisé 700 comprend, dans cet ordre et le long de sa direction principale d'allongement A, une première plateforme 711, la partie centrale 710 et une deuxième plateforme 711. As illustrated in FIG. 7, the chassis 701 of the automated device 700 comprises a central part 710 carrying in particular a screwing device 750 configured to receive the screwing tool 100, and two platforms 711 arranged on the side and other of the central part 710. In other words, the automated device 700 comprises, in this order and along its main direction of elongation A, a first platform 711, the central part 710 and a second platform 711.
Une plateforme 711 comprend un plateau 712, au moins un moyen de mise en mouvement 713 du dispositif automatisé 700 et un organe de maintien 714 du dispositif automatisé contre le panneau. Selon un exemple, l’organe de maintien 714 est un organe d’aspiration qui plaque par dépression le dispositif automatisé contre la face exposée du panneau de construction. Dans un tel cas, le plateau 712 est pourvu d’un passage par lequel l’air est aspiré en vue de générer une dépression. Le plateau 712 comprend une bande périphérique extérieure où est disposé un dispositif d’étanchéité 715. L’espace entre le plateau 712, le panneau de construction non représenté sur la figure 7, et le dispositif d’étanchéité 715 forme une chambre de dépression, cette dernière disposant d’une bouche d’aspiration destinée à être positionnée contre le panneau de construction. A platform 711 comprises a plate 712, at least one means for setting in motion 713 of the automated device 700 and a member 714 for holding the automated device against the panel. According to one example, the holding member 714 is a suction member which presses the automated device by vacuum against the exposed face of the building panel. In such a case, the plate 712 is provided with a passage through which the air is sucked in order to generate a vacuum. The plate 712 comprises an outer peripheral strip where a sealing device 715 is disposed. The space between the plate 712, the construction panel not shown in FIG. 7, and the sealing device 715 forms a vacuum chamber, the latter having a suction mouth intended to be positioned against the construction panel.
Selon l'exemple de réalisation plus particulièrement illustré par la figure 7, le dispositif automatisé 700 comprend deux organes de maintien 714 disposés de part et d’autre du dispositif de vissage 750, selon la direction principale d'allongement A du dispositif automatisé 700.
