Abstract
Description
L'invention se rapporte à un dispositif générateur d'au moins un jet de fluide gazeux orienté mais mobile dans une direction sensiblement perpendiculaire à cette orientation.The invention relates to a device generating at least one jet of gaseous fluid oriented but mobile in a direction substantially perpendicular to this orientation.
L'invention concerne plus particulièrement mais non exclusivement un dispositif en vue du dépoussierage automatique de sous-ensembles mécaniques de machines textiles afin d'y empêcher l'accumulation de particules et/ou poussières, lesquelles sont notamment susceptibles d'engendrer des disfonctionnements.The invention relates more particularly but not exclusively to a device for the automatic dedusting of mechanical subassemblies of textile machines in order to prevent the accumulation of particles and / or dust, which are in particular liable to cause malfunctions.
Par exemple, ce type de dispositif trouve une application avantageuse dans le dépoussierage des ressorts de rappel de lisses en vue d'y entraver la formation de la bourre.For example, this type of device finds an advantageous application in the dusting of heald return springs in order to impede the formation of the flock therein.
Dans ce domaine, il est connu de réaliser des dispositifs de soufflage générant une pluralité de jets d'air, chacun localisé au droit de l'organe mécanique à préserver de la poussière (FR-A-2.570.719 et 2.537.167).In this field, it is known to produce blowing devices generating a plurality of air jets, each located at the level of the mechanical member to be protected from dust (FR-A-2,570,719 and 2,537,167).
Ces dispositifs donnent de bons résultats mais on leur reproche, d'une part, d'être de construction onéreuse et, d'autre part, d'être voraces en énergie.These devices give good results but they are criticized, on the one hand, for being expensive to build and, on the other hand, for being energy-hungry.
En effet, ces dispositifs mettent en oeuvre une pluralité de buses et/ou d'orifices qu'il faut positionner de manière adéquate sur chaque machine considérée et oblige l'utilisation d'une puissante installation de soufflage compte tenu du débit de fluide requis par l'ensemble des buses et/ou orifices.Indeed, these devices use a plurality of nozzles and / or orifices which must be positioned adequately on each machine considered and obliges the use of a powerful blowing installation taking into account the fluid flow required by all the nozzles and / or orifices.
Un autre inconvénient des dispositifs du type précité est qu'ils sont bruyants.Another drawback of devices of the aforementioned type is that they are noisy.
Un résultat que l'invention vise à obtenir est justement un dispositif de soufflage dont le niveau sonore soit amoindri.A result which the invention aims to obtain is precisely a blowing device whose noise level is reduced.
Un autre résultat que l'invention vise à obtenir est un dispositif de soufflage qui, d'emblée, puisse être associé à diverses machines ou installations sans modifications de ces dernières.Another result which the invention aims to obtain is a blowing device which, from the outset, can be associated with various machines or installations without modifications of the latter.
Un autre résultat que l'invention vise à obtenir est un dispositif qui soit de construction robuste et peu onéreuse.Another result which the invention aims to obtain is a device which is of robust construction and inexpensive.
A cet effet, l'invention a pour objet un dispositif du type précité, lequel est notamment caractérisé en ce qu'il comprend :
- un caisson creux, notamment sensiblement parallélépipédique rectangle et à parois rigides, lequel caisson présente au moins une face longitudinale comportant au moins une fenêtre qui s'étend approximativement sur toute la dimension longitudinale de la dite face et qui est constituée par au moins une découpe exécutée dans toute l'épaisseur de la paroi considérée,
- fermant étanchement chaque fenetre précitée, au droit de ses bords, au moins une bande souple qui présente localement au moins une perforation de dimensions prédéterminées,
- un moyen d'entraînement de chaque bande selon l'axe longitudinal de la fenêtre au droit de laquelle elle se situe, et ce de manière à déplacer chaque perforation de la bande concernée selon la dimension longitudinale de la fenetre,
- un moyen d'injection de fluide gazeux, notamment d'air, dans le caisson au travers d'une ouverture ménagée dans l'une de ses parois.
- a hollow box, in particular a substantially rectangular parallelepiped and with rigid walls, which box has at least one longitudinal face comprising at least one window which extends approximately over the entire longitudinal dimension of said face and which consists of at least one cut made throughout the thickness of the wall considered,
- sealingly closing each aforementioned window, in line with its edges, at least one flexible strip which locally has at least one perforation of predetermined dimensions,
- means for driving each strip along the longitudinal axis of the window to the right of which it is located, so as to move each perforation of the strip concerned according to the longitudinal dimension of the window,
- a means for injecting gaseous fluid, in particular air, into the box through an opening made in one of its walls.
L'invention sera bien comprise à l'aide de la description ci-aprés faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement une vue en perspective éclatée du dispositif selon l'invention.The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents an exploded perspective view of the device according to the invention.
En se reportant au dessin, on voit un dispositif générateur 1 d'au moins un jet de fluide 2 gazeux orienté dans une direction D1 mais mobile dans une direction D2 sensiblement perpendiculaire à la direction d'orientation D1.Referring to the drawing, there is seen a device 1 for generating at least one jet of gaseous fluid 2 oriented in a direction D1 but movable in a direction D2 substantially perpendicular to the direction of orientation D1.
Tel que cela apparaît au dessin, le jet de fluide est mobile au moins entre deux positions P1, P2 dont l'écartement est approximativement déterminé par la dimension longitudinale L du dispositif de soufflage.As shown in the drawing, the fluid jet is movable at least between two positions P1, P2, the spacing of which is approximately determined by the longitudinal dimension L of the blowing device.
Conformément à l'invention, le dispositif comprend :
- un
caisson 3 creux, notamment sensiblement parallélépirédique rectangle et à parois 3a rigides, lequel caisson présente au moins une face longitudinale 4 comportant au moins unefenêtre 5 qui s'étend approximativement sur toute la dimension longitudinale de la dite face et qui est constituée par au moins une découpe exécutée dans toute l'épaisseur de la paroi considérée, - fermant étanchement chaque
fenêtre 5 précitée, au droit de sesbords 6, au moins une bande 7 souple qui présente localement au moins uneperforation 8 de dimensions prédéterminées, - un moyen 9 d'entraînement de chaque bande 7 selon l'axe longitudinal 5a de la
fenêtre 5 au droit de laquelle elle se situe, et ce de manière à déplacer chaque perforation de la bande concernée selon la dimension longitudinale de la fenetre, - un
moyen 10 d'injection de fluide gazeux, notamment d'air, dans lecaisson 3 au travers d'une ouverture 11 ménagée dans l'une de ses parois.
- a
hollow box 3, in particular substantially rectangular parallelepiredic and with rigid walls 3a, which box has at least one longitudinal face 4 comprising at least onewindow 5 which extends approximately over the entire longitudinal dimension of said face and which is constituted by at minus a cut made in the entire thickness of the wall considered, - sealingly closing each
aforementioned window 5, in line with itsedges 6, at least one flexible strip 7 which locally has at least oneperforation 8 of predetermined dimensions, - a means 9 for driving each strip 7 along the longitudinal axis 5a of the
window 5 to the right of which it is located, so as to move each perforation of the strip concerned according to the longitudinal dimension of the window, - a
means 10 for injecting gaseous fluid, in particular air, into thebox 3 through an opening 11 formed in one of its walls.
Le moyen 10 d'injection de fluide gazeux dans le caisson consiste par exemple en une soufflerie (symbolisée en traits mixtes forts) par exemple raccordée au caisson par le biais d'une conduite.The
L'expulsion de l'air injecté dans le caisson s'effectue donc par chaque perforation de la bande ce qui crée un jet d'orientation approximativement perpendiculaire au secteur de la bande contenant l'orifice considéré.The air injected into the box is therefore expelled by each perforation of the strip, which creates a jet of orientation approximately perpendicular to the sector of the strip containing the orifice considered.
Le déplacement de la bande selon l'axe longitudinal 5a de la fenêtre 5 engendre donc le déplacement de chaque jet selon une direction D2 approximativement perpendiculaire à son orientation D1 et ce dans les limites de la fenêtre.The displacement of the strip along the longitudinal axis 5a of the
Le dispositif exposé permet donc d'obtenir le résultat essentiel visé par l'invention à savoir la construction à moindre coût d'un dispositif de soufflage notamment pour le dépoussiérage de sous-ensembles de machines textiles (non représentées) qui comprennent une pluralité d'organes implantés côte à côte sur une zone allongée.The exposed device therefore makes it possible to obtain the essential result targeted by the invention, namely the construction at a lower cost of a blowing device, in particular for the dedusting of textile machine subassemblies (not shown) which comprise a plurality of organs implanted side by side on an elongated area.
Le dispositif selon l'invention permet donc avec un débit d'air limité d'assurer la protection d'un site longitudinalement étendu puisque, d'une part, l'échappement de fluide est limité à la section totale des perforations qui, s'étendant essentiellement sur la largeur de la bande dans une zone longitudinalement limitée, débouchent dans la fenêtre du caisson et, d'autre part, ces perforations décrivent toute la fenêtre dont la dimension longitudinale est choisie selon le site.The device according to the invention therefore makes it possible with a limited air flow to ensure the protection of a longitudinally extended site since, on the one hand, the escape of fluid is limited to the total section of the perforations which, extending essentially over the width of the strip in a longitudinally limited area, open into the window of the box and, on the other hand, these perforations describe the whole window, the longitudinal dimension of which is chosen according to the site.
Tel que cela sera souligné plus aprés, le dispositif de l'invention met en oeuvre un mécanisme trés simple.As will be emphasized later, the device of the invention implements a very simple mechanism.
Bien que cela n'apparaisse pas de manière évidente sur le dessin, on comprend que compte tenu du mécanisme mis en oeuvre les dimensions notamment transversales du dispositif peuvent être fixées à de faibles valeurs, sans que cela ne remette en cause le fonctionnement de ce dispositif, ce qui en permet l'intégration à des machines n'offrant qu'un volume d'accueil trés étroit.Although this does not appear in an obvious way on the drawing, it is understood that taking into account the mechanism implemented the dimensions in particular transverse of the device can be fixed at low values, without that calling into question the operation of this device , which allows its integration into machines offering only a very narrow reception volume.
Conformément à l'invention, d'une part, chaque bande souple 7 est du type sans fin c'est à dire qu'elle forme une boucle et, d'autre part, le moyen 9 d'entrainement de cette bande comprend au moins deux organes 12 de renvoi et/ou de tension sur lesquels la dite bande circule et au moins un organe moteur 13 de commande en rotation d'au moins l'un de ses organes de renvoi et/ou de tension 12.According to the invention, on the one hand, each flexible strip 7 is of the endless type, that is to say that it forms a loop and, on the other hand, the means 9 for driving this strip comprises at least two return and / or
De préférence, l'entraînement de la bande est commandé en continu dans un seul sens mais cela n'est pas limitatif.Preferably, the drive of the strip is controlled continuously in one direction but this is not limiting.
L'organe moteur 13 est par exemple un ensemble moto-réducteur de type électrique.The
Suivant l'invention, les organes 12 de renvoi consistent en des rouleaux sensiblement cylindriques de révolution et ces derniers sont chacun guidés en rotation par un moyen 14 à cet effet, lequel est quant à lui solidaire du caisson.According to the invention, the
Conformément à l'invention, chaque fenêtre 5 devant laquelle circule une bande 7 souple est constituée d'une découpe unique réalisée dans l'épaisseur de la paroi 3a du caisson 3 qui constitue la face concernée et cette fenêtre 5 est équipée d'une grille 15 à large maille et dont au moins certains des éléments constitutifs 16 longitudinaux et/ou transversaux offrent une face d'appui et de glissement contre laquelle la bande 7 vient s'appuyer notamment sous l'effet de la pression de fluide interne au caisson.According to the invention, each
Selon l'invention, au moins l'un des bords latéraux 7a de chaque bande coopère avec une glissière rectiligne 17 de guidage qui est solidaire du caisson.According to the invention, at least one of the
De préférence, chaque bande sans fin comprend au moins deux perforations qui sont espacées sur la bande de manière telle qu'au moins l'une d'entre elles soit toujours inscrite dans la fenêtre.Preferably, each endless strip comprises at least two perforations which are spaced apart on the strip so that at least one of them is always inscribed in the window.
Tel que cela est représenté mais non limitativement pour l'invention, le dispositif comprend une seule bande souple sans fin dont la largeur s'étend selon sensiblement toute la largeur de la face du caisson qu'elle équipe.As shown but not limited to the invention, the device comprises a single endless flexible strip whose width extends along substantially the entire width of the face of the box which it equips.
Egalement de manière non limitative, la bande comprend au moins une groupe de perforations disposées en quinconce, lequel groupe s'étend essentiellement selon la largeur de la bande.Also without limitation, the strip comprises at least one group of perforations arranged in staggered rows, which group extends essentially along the width of the strip.
Dans un mode préféré de réalisation, le dispositif comporte au moins une conduite 18 raccordée au caisson débouchant au droit de l'organe moteur 13.In a preferred embodiment, the device comprises at least one
Par cela, on obtient avantageusement le dépoussierage du dit organe moteur.By this, advantageously the dusting of said driving member is obtained.
