DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne un procédé de nettoyage d'une machine de tressage ou de surtressage, en particulier de câbles électriques. La tresse ou surtresse forme par exemple une protection au câble.The present invention relates to a method of cleaning a braiding or overbraiding machine, in particular electric cables. The braid or surtresse forms for example a protection cable.

ETAT DE L'ARTSTATE OF THE ART

L'état de l'art comprend notamment le document US-A1-2,237,858 .The state of the art includes the document US-A1-2,237,858 .

Une machine de tressage, telle que celle représentée aux figures 1 et 2 et désignée par la référence 10, comporte un plateau 12 de support d'une rangée annulaire d'organes 14 d'entraînement de fuseaux 16. Les organes 14 s'étendent autour d'un premier même axe A et sont mobiles en rotation autours de seconds axes B sensiblement parallèles entre eux et au premier axe A.A braiding machine, such as that shown in figures 1 and 2 and designated by the reference 10, comprises a support plate 12 of an annular row of members 14 for driving spindles 16. The members 14 extend around a first same axis A and are rotatable around second axes B substantially parallel to each other and to the first axis A.

Les organes 14, mieux visibles à la figure 3, comportent chacun d'une part un pignon 18 engrené avec des pignons 18 d'organes adjacents et d'autre part une roue 20 comportant à sa périphérie des encoches 22 configurées pour recevoir des moyens complémentaires 24 des fuseaux 16 en vue de leur entraînement autour des seconds axes B.The organs 14, better visible at the figure 3 , each comprise on the one hand a pinion 18 meshing with pinions 18 of adjacent members and secondly a wheel 20 having at its periphery notches 22 configured to receive complementary means 24 of the spindles 16 for their training around second axes B.

Comme cela est visible aux figures 6 et 7, chaque fuseau 16 comprend une base inférieure 26 et une bobine supérieure de fils 28. La base 26 comporte ici deux plaques 30 parallèles, respectivement supérieure et inférieure. Les plaques 30 sont espacées l'une de l'autre et reliées ensemble par des tiges formant lesdits moyens complémentaires 24. La roue 20 est destinée à être engagée entre les plaques 30, ses encoches 22 recevant les tiges en vue de leur entraînement en rotation (figure 3).As can be seen in Figures 6 and 7 each spindle 16 comprises a lower base 26 and an upper spool of threads 28. The base 26 here comprises two parallel plates 30, respectively upper and lower. The plates 30 are spaced from one another and connected together by rods forming said complementary means 24. The wheel 20 is intended to be engaged between the plates 30, its notches 22 receiving the rods for their rotational drive ( figure 3 ).

Le plateau 12 comporte des moyens de guidage des fuseaux 16, qui comportent, pour chacun des organes 14, un chemin ou une rainure annulaire 32 de glissement s'étendant autour du second axe B de l'organe correspondant et configuré pour recevoir au moins un élément 34 de guidage de chaque fuseau en vue de son guidage autour du second axe B. Chaque chemin de glissement 32 est relié par des moyens d'aiguillage 36 (figures 4 et 5) à des chemins de glissement 32 adjacents en vue du déplacement en rotation des fuseaux 16 autour du premier axe A par transfert des fuseaux des organes aux organes adjacents.The plate 12 comprises means for guiding the spindles 16, which comprise, for each of the members 14, an annular sliding path or groove 32 extending around the second axis B of the corresponding member and configured to receive at least one element 34 for guiding each spindle so as to guide it around the second axis B. Each sliding path 32 is connected by switch means 36 ( Figures 4 and 5 ) to adjacent sliding paths 32 for the rotational movement of the spindles 16 around the first axis A by transfer of the spindles of the organs to the adjacent members.

Les chemins de glissement 32 doivent être régulièrement nettoyés pour y retirer les résidus de graisse et les éventuels morceaux de fils. Dans la technique actuelle, cet entretien est réalisé manuellement, comme représenté en figure 8. Les chemins de glissement ont une largeur relativement faible et sont actuellement nettoyés au moyen d'un tissu de coton qui est déplacé dans les chemins de glissement au moyen par exemple d'une spatule de chimiste. Cette opération d'entretien est longue et fastidieuse. Elle représente en outre un risque non négligeable pour l'opérateur qui manipule la spatule de se blesser en déplaçant le tissu de coton dans les chemins de glissement.The sliding paths 32 must be regularly cleaned to remove grease residues and any pieces of wire. In the current technique, this interview is done manually, as shown in figure 8 . The sliding paths have a relatively small width and are currently cleaned by means of a cotton fabric which is moved in the sliding paths by means for example of a chemistry spatula. This maintenance operation is long and tedious. It also represents a significant risk for the operator who manipulates the spatula to injure itself by moving the cotton fabric in the sliding paths.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Bien que la machine de tressage 10 de la figure 1 ait été décrite dans ce qui précède, elle sera décrite plus en détail dans ce qui suit.Although the braiding machine 10 of the figure 1 has been described in the foregoing, it will be described in more detail in the following.

La machine 10 comprend une table dont le plateau supérieur forme le plateau 12 précité. Le plateau 12 est sensiblement horizontal dans l'exemple représenté. Il porte une cheminée centrale 40 d'axe vertical A et autour de laquelle s'étend la rangée d'organes 14. La cheminée 40 s'étend vers le haut depuis le plateau 12 et porte à son extrémité supérieure un premier anneau 42 d'axe A de révolution.The machine 10 comprises a table whose upper plate forms the plate 12 above. The plate 12 is substantially horizontal in the example shown. It carries a central chimney 40 of vertical axis A and around which extends the row of members 14. The chimney 40 extends upwards from the plate 12 and carries at its upper end a first ring 42 of axis A of revolution.

Un second anneau 44 d'axe A de révolution est disposé au-dessus du premier anneau 42 et à distance de celui-ci pour autoriser le passage de fils entre les anneaux 42, 44. Le second anneau 44 est relié par des barres 46 sensiblement horizontales aux extrémités supérieures de tiges verticales 48 dont les extrémités inférieures sont fixées sur le plateau 12. Les tiges 48, ici au nombre de trois, sont régulièrement réparties autour de l'axe A.A second ring 44 of axis A of revolution is disposed above the first ring 42 and at a distance therefrom to allow the passage of wires between the rings 42, 44. The second ring 44 is connected by bars 46 substantially horizontal to the upper ends of vertical rods 48 whose lower ends are fixed on the plate 12. The rods 48, here three in number, are regularly distributed around the axis A.

La roue 22 de chaque organe 14 est située au-dessus du plateau 12 et son pignon 18 est situé au-dessous du plateau 12. Les pignons 18 des organes 14 sont engrenés les uns avec les autres et avec un pignon de sortie d'un moteur 50, associé ici à un réducteur 52. Le moteur 50 entraîne un premier organe 14 en rotation dans le sens horaire (ou anti-horaire) ce qui va provoquer l'entraînement des organes adjacents dans le sens contraire. Ainsi, comme cela est schématiquement représenté par les flèches en figure 4, une moitié des organes 14 tournent dans le sens horaire et l'autre moitié des organes tournent dans le sens anti-horaire.The wheel 22 of each member 14 is located above the plate 12 and its pinion 18 is located below the plate 12. The pinions 18 of the members 14 are meshed with each other and with an output pinion of a motor 50, here associated with a gearbox 52. The motor 50 drives a first member 14 in rotation in the clockwise direction (or anti-clockwise) which will cause the driving of the adjacent members in the opposite direction. So, as is schematically represented by the arrows in figure 4 one half of the members 14 rotate clockwise and the other half of the members rotate counterclockwise.

Les moyens de guidage des fuseaux 16 comprennent une rangée annulaire de secteurs 54 fixés sur le plateau 12 et définissant chacun le chemin de glissement 32 de l'organe 14 correspondant. Chaque secteur 54 est ici formé par un bloc métallique dans lequel le chemin 32 est formé par usinage. Les secteurs 54 sont disposés circonférentiellement bout à bout les uns à côté des autres, autour de l'axe A, et comprennent à leurs extrémités circonférentielles des logements 56 de réception de moyens d'aiguillage 36.The guide means of the spindles 16 comprise an annular row of sectors 54 fixed on the plate 12 and each defining the sliding path 32 of the member 14 corresponding. Each sector 54 is here formed by a metal block in which the path 32 is formed by machining. The sectors 54 are arranged circumferentially end-to-end next to each other around the axis A, and comprise at their circumferential ends receiving means 56 for receiving switching means 36.

Dans l'exemple représenté aux figures 4 et 5, ces moyens d'aiguillage sont des disques 36. A chaque extrémité circonférentielle d'un secteur 54, le chemin de glissement est interrompu par le logement 56. Le disque d'aiguillage 36 comprend deux portions de chemin entrecroisées, en X, qui relient les extrémités circonférentielles du chemin d'un secteur aux extrémités circonférentielles du chemin du secteur adjacent (figures 4 et 5).In the example shown in Figures 4 and 5 these switching means are discs 36. At each circumferential end of a sector 54, the sliding path is interrupted by the housing 56. The switching disc 36 comprises two intersecting path portions, in X, which connect the circumferential ends of the path of one sector at the circumferential ends of the adjacent sector road ( Figures 4 and 5 ).

Chaque fuseau 16 comprend une base inférieure 26 et une bobine supérieure de fils 60. Les figures 6 et 7 montrent une base 26 qui comprend notamment deux plaques 30 superposées, respectivement inférieure et supérieure. Les plaques 30 ont un contour périphérique de forme elliptique ou oblongue. Elles sont espacées l'une de l'autre et reliées ensemble par des tiges 62 sensiblement verticales visibles à la figure 2. L'espace inter-plaques est configuré pour recevoir une portion périphérique de la roue 20 d'un organe 14, les tiges 62 étant destinées à être engagées dans les encoches 22 de la roue 20. La coopération des tiges 62 avec les encoches 22 et l'entraînement en rotation des organes 14 va se traduire par un entraînement en rotation des fuseaux 16.Each spindle 16 comprises a lower base 26 and an upper spool of threads 60. Figures 6 and 7 show a base 26 which comprises in particular two superimposed plates 30, respectively lower and upper. The plates 30 have a peripheral contour of elliptical or oblong shape. They are spaced from each other and connected together by substantially vertical rods 62 visible to the figure 2 . The inter-plate space is configured to receive a peripheral portion of the wheel 20 of a member 14, the rods 62 being intended to be engaged in the notches 22 of the wheel 20. The cooperation of the rods 62 with the notches 22 and the rotational drive of the members 14 will result in a rotation of the spindles 16.

La plaque supérieure 30 porte des moyens 64 de fixation de la bobine 60. La plaque inférieure 30 comprend des logements cylindriques 66 de réception et de guidage en rotation autour d'axes verticaux C parallèles des éléments de guidage 34. Chaque élément de guidage 34 comprend un organe cylindrique supérieur 68 engagé avec de faibles jeux dans le logement 66 correspondant, et une ogive inférieure 70 destinée à être engagée dans les chemins de glissement 32 et les disques d'aiguillage 36 et à coopérer avec eux pour guider les fuseaux 16 en rotation autour des axes A et B.The upper plate 30 carries means 64 for fixing the coil 60. The lower plate 30 comprises cylindrical housings 66 for receiving and guiding in rotation about parallel vertical axes C of the guide elements 34. Each guide element 34 comprises an upper cylindrical member 68 engaged with small gaps in the corresponding housing 66, and a lower ogive 70 intended to be engaged in the sliding paths 32 and the switch discs 36 and to cooperate with them to guide the spindles 16 in rotation around axes A and B.

Chaque ogive 70 a une forme allongée et comprend un corps central comportant deux surfaces latérales 70a parallèles, et des extrémités avant et arrière en pointe. Chacune de ces extrémités comprend deux surfaces latérales 70b inclinées. Enfin, chaque ogive 70 comprend une surface inférieure 70c sensiblement perpendiculaire à l'axe C.Each warhead 70 has an elongated shape and comprises a central body having two parallel side surfaces 70a, and front and rear ends pointed. Each of these ends comprises two inclined lateral surfaces 70b. Finally, each nose 70 comprises a lower surface 70c substantially perpendicular to the axis C.

La machine 10 comporte en outre des moyens d'entraînement ou d'enroulement d'un câble en vue de son tressage ou surtressage. Ces moyens sont portés par le plateau 12 et comprennent un bras vertical 72 (figure 1) portant une roue 74 d'entraînement autour d'un axe horizontal D d'un câble (non représenté) destiné à passer à l'intérieur de la cheminée 40 et d'un cerclage de guidage 76 disposé au-dessus des deux anneaux 42, 44. Un rouleau de câble non encore tressé peut être situé sous le plateau 12, dans des moyens de stockage 78.The machine 10 further comprises means for driving or winding a cable for braiding or overbraiding. These means are carried by the plate 12 and comprise a vertical arm 72 ( figure 1 ) carrying a drive wheel 74 about a horizontal axis D of a cable (not shown) for passing inside the chimney 40 and a guide ring 76 disposed above the two rings 42 44. A roll of cable not yet braided may be located under the tray 12 in storage means 78.

La machine de tressage 10 fonctionne de la façon suivante. Le câble qui doit être entouré par une tresse est déplacé du bas vers le haut à travers la cheminée 40 et le cerclage 76, par entraînement par la roue 74. Les fuseaux 16 sont montés sur les roues 20, les tiges 70 des bases 26 des fuseaux 16 étant engagées dans les encoches 22 des roues 20 des organes 14. Les fils des fuseaux 16 passent entre les anneaux 42, 44 et sont entrecroisés sur le câble à mesure qu'il se déplace vers le haut. Pour cela, chaque fuseau 16 est entraîné en rotation autour de l'axe B par un organe 14, par coopération avec le chemin de glissement 32 correspondant, puis est transféré à un autre organe pour tourner autour de l'axe B de cet autre organe, par coopération d'une part avec la portion de chemin du disque 36 situé entre les organes et d'autre part par le chemin de glissement de cet autre organe. Une partie des fuseaux 16 tournent dans le sens horaire autour de l'axe A et l'autre partie des fuseaux tournent dans le sens anti-horaire autour de l'axe A.The braiding machine 10 operates as follows. The cable to be surrounded by a braid is moved from bottom to top through the chimney 40 and the strapping 76, driven by the wheel 74. The spindles 16 are mounted on the wheels 20, the rods 70 of the bases 26 of the The spindles 16 being engaged in the notches 22 of the wheels 20 of the members 14. The spindle threads 16 pass between the rings 42, 44 and are intertwined on the cable as it moves upwards. For this, each spindle 16 is rotated about the axis B by a member 14, by cooperation with the corresponding sliding path 32, and is then transferred to another member to rotate about the axis B of this other member , by cooperation on the one hand with the path portion of the disc 36 located between the members and on the other hand by the sliding path of this other member. A portion of the spindles 16 rotate clockwise about the axis A and the other part of the spindles turn counterclockwise about the axis A.

Comme expliqué dans ce qui précède, le nettoyage des chemins de glissement 32 est long et fastidieux car il est réalisé manuellement au moyen d'un tissu de coton 80 et d'une spatule métallique 82 qui est utilisée pour déplacer le tissu 80 dans le chemin de chaque secteur et d'un chemin à l'autre (figure 8).As explained above, the cleaning of the sliding paths 32 is long and tedious because it is done manually by means of a cotton fabric 80 and a metal spatula 82 which is used to move the fabric 80 in the path each sector and from one path to another ( figure 8 ).

La présente invention apporte une solution simple, efficace et économique à ce problème grâce à un outil de nettoyage 84.The present invention provides a simple, effective and economical solution to this problem with a cleaning tool 84.

Les figures 9 et 10 représentent un mode de réalisation de l'outil de nettoyage 84 selon l'invention. Cet outil 84 comprend une base 86 similaire à la base 26 d'un fuseau 16, de façon à ce que l'outil puisse coopérer avec les organes et à être entraîné par ceux-ci comme expliqué dans ce qui précède.The Figures 9 and 10 represent an embodiment of the cleaning tool 84 according to the invention. This tool 84 comprises a base 86 similar to the base 26 of a spindle 16, so that the tool can cooperate with the bodies and be driven by them as explained in the foregoing.

La base 86 comprend deux plaques 88 superposées, respectivement inférieure et supérieure. Les plaques 88 ont un contour périphérique de forme elliptique ou oblongue. Elles sont espacées l'une de l'autre et reliées ensemble par des tiges 90 sensiblement verticales. L'espace inter-plaques est configuré pour recevoir une portion périphérique de la roue 20 d'un organe 14, les tiges 90 étant destinées à être engagées dans les encoches 22 de la roue 20. La coopération des tiges 90 avec les encoches 22 et l'entraînement en rotation des organes 14 va se traduire par un entraînement en rotation de l'outil 84.The base 86 comprises two superimposed plates 88, lower and upper respectively. The plates 88 have a peripheral contour of elliptical or oblong shape. They are spaced from each other and connected together by rods 90 substantially vertical. The inter-plate space is configured to receive a peripheral portion of the wheel 20 of a member 14, the rods 90 being intended to be engaged in the notches 22 of the wheel 20. The cooperation of the rods 90 with the notches 22 and the rotational drive of the members 14 will result in a rotational drive of the tool 84.

La plaque supérieure 88 peut porter des moyens 92 de préhension de l'outil. Comme pour la base 26, la plaque inférieure 88 comprend des logements cylindriques 94 de réception et de guidage en rotation autour d'axes verticaux C parallèles des éléments de guidage 96. Chaque élément de guidage 96 comprend un organe cylindrique supérieur 98 engagé avec de faibles jeux dans le logement 96 correspondant, et une ogive inférieure 100, 100' destinée à être engagée dans les chemins de glissement 32 et les disques d'aiguillage 36 et à coopérer avec eux pour guider les fuseaux 16 en rotation autour des axes A et B.The upper plate 88 may carry means 92 for gripping the tool. As for the base 26, the bottom plate 88 comprises cylindrical housings 94 for receiving and guiding in rotation about parallel vertical axes C of the guide elements 96. Each guide element 96 comprises an upper cylindrical member 98 engaged with small gaps in the corresponding housing 96, and a lower ogive 100, 100 intended to be engaged in the sliding paths 32 and the switch discs 36 and to cooperate with them to guide the spindles 16 in rotation about the axes A and B.

L'ogive arrière 100 a une forme allongée et comprend un corps central comportant deux surfaces latérales 100a parallèles, et des extrémités avant et arrière en pointe. Chacune de ces extrémités comprend deux surfaces latérales 100b inclinées. Enfin, l'ogive 100 comprend une surface inférieure 100c sensiblement perpendiculaire à l'axe C.The rear warhead 100 has an elongate shape and comprises a central body having two parallel side surfaces 100a, and front and rear ends pointed. Each of these ends comprises two inclined lateral surfaces 100b. Finally, the ogive 100 comprises a lower surface 100c substantially perpendicular to the axis C.

L'ogive avant 100' a une forme allongée et comprend un corps central comportant deux surfaces latérales 100a parallèles, et une extrémité arrière en pointe qui comprend deux surfaces latérales 100b inclinées. L'ogive 100' comprend en outre une surface inférieure 100c sensiblement perpendiculaire à l'axe C.The ogive before 100 'has an elongate shape and comprises a central body having two parallel side surfaces 100a, and a rear end pointed which comprises two inclined lateral surfaces 100b. The ogive 100 'further comprises a lower surface 100c substantially perpendicular to the axis C.

L'ogive 100' étant configurée pour entraîner ou pour être équipé d'un moyen de nettoyage, tel qu'un morceau ou tissu de coton, des chemins de glissement 32. Dans l'exemple représenté, l'extrémité avant de l'ogive avant 100' comprend une troncature qui définit une surface 100d inclinée par rapport à la surface 100c et sensiblement perpendiculaire à un plan longitudinal P de l'ogive 100' passant par son axe C. Par ailleurs, l'ogive 100' est raccourcie et donc plus courte que l'ogive 100, son extrémité avant présentant un bord avant de forme arrondie, sensiblement autour dudit axe C.The warhead 100 'being configured to drive or to be equipped with a cleaning means, such as a piece or fabric of cotton, sliding paths 32. In the example shown, the front end of the warhead before 100 'comprises a truncation which defines a surface 100d inclined relative to the surface 100c and substantially perpendicular to a longitudinal plane P of the ogive 100' passing through its axis C. Moreover, the ogive 100 'is shortened and therefore shorter than the warhead 100, its front end having a rounded front edge substantially around said axis C.

La surface 100d est une surface d'appui et d'entraînement du morceau de coton 80, qui est donc destiné à être déplacé dans les chemins de glissement 32 en vue de leur nettoyage à mesure que l'outil est déplacé par les organes 14.The surface 100d is a bearing and driving surface of the piece of cotton 80, which is therefore intended to be moved in the sliding paths 32 for cleaning as the tool is moved by the members 14.

Le nettoyage des chemins de glissement 32 de la machine de tressage 10 peut être réalisé de la façon suivante. Au moins un outil 84 est monté sur un organe 14, les tiges 90 de sa base 86 étant engagées dans les encoches 22 de la roue 20 de cet organe 14. Les ogives 100, 100' de la base sont engagées dans le chemin de glissement 32 correspondant et un morceau de coton 80 est disposé en avant de l'ogive avant, et calé entre le fond du chemin de glissement et la surface 100d de l'ogive 100'. L'outil 84 est entraîné en rotation autour de l'axe B par l'organe 14, par coopération avec le chemin de glissement 32 correspondant, puis est transféré à un autre organe pour tourner autour de l'axe B de cet autre organe, par coopération d'une part avec la portion de chemin du disque 36 situé entre les organes et d'autre part par le chemin de glissement de cet autre organe. L'outil 84 tourne dans le sens horaire (ou anti-horaire, respectivement) autour de l'axe A, ce qui permet de nettoyer une moitié des chemins de glissement 32. L'outil est retiré de l'organe et monté sur un organe directement adjacent et les étapes précitées sont répétées de façon à ce que l'outil 84 tourne dans le sens anti-horaire (ou horaire, respectivement) autour de l'axe A, ce qui permet de nettoyer l'autre moitié des chemins de glissement 32.The cleaning of the sliding paths 32 of the braiding machine 10 can be carried out as follows. At least one tool 84 is mounted on a member 14, the rods 90 of its base 86 being engaged in the notches 22 of the wheel 20 of this member 14. The warheads 100, 100 'of the base are engaged in the sliding path 32 corresponding and a piece of cotton 80 is disposed in front of the front warhead, and wedged between the bottom of the sliding path and the surface 100d of the warhead 100 '. The tool 84 is rotated about the axis B by the member 14, in cooperation with the corresponding sliding path 32, and is then transferred to another member to rotate around the axis B of this other member, by cooperation on the one hand with the path portion of the disc 36 located between the members and on the other hand by the sliding path of the other member. The tool 84 rotates clockwise (or counterclockwise, respectively) about the axis A, which makes it possible to clean half of the sliding paths 32. The tool is removed from the member and mounted on a directly adjacent member and the aforementioned steps are repeated so that the tool 84 rotates counterclockwise (or clockwise, respectively) about the axis A, which allows to clean the other half of the paths of slip 32.
