Description
La présente invention concerne le domaine du marquage de sols, en particulier de chaussées et d'aires de stationnement, au moyen de bandes de marquage et a pour objet un dispositif autonome de pose de telles bandes.The present invention relates to the field of soil marking, in pavements and parking areas, using marking and relates to an autonomous device for laying such strips.
Actuellement, le marquage horizontal des aires de stationnement, ainsi que le marquage provisoire de chaussées, notamment de voies de circulation provisoires sur des chaussées en travaux, sont généralement réalisés au moyen de bandes, éventuellement autocollantes, appliquées avec un apport de chaleur et de pression. La mise en place des bandes est généralement réalisée manuellement par découpe préalable, puis application sur le sol, éventuellement avec un apport de chaleur et d'une pression supplémentaire au moyen d'un dispositif approprié. Pour l'application de bandes autocollantes, un décollement préalable du film de protection de leur face adhésive est nécessaire, compliquant partiellement les travaux de pose et entraínant une perte de temps correspondante. En outre, la pose manuelle de ces bandes, qui sont relativement lourdes, nécessite le plus souvent au moins deux opérateurs et est relativement pénible.Currently, horizontal marking of parking areas, as well as the provisional marking of pavements, in particular of traffic lanes temporary works on roadways under construction, are generally carried out by means of strips, possibly adhesive, applied with a contribution of heat and pressure. The placing of the tapes is usually done manually by preliminary cutting, then application on the ground, possibly with a contribution of heat and additional pressure by means of a suitable device. For the application of adhesive strips, a detachment of the film of protection of their adhesive side is necessary, partially complicating the laying work and resulting in a corresponding loss of time. In addition, the pose these bands, which are relatively heavy, usually require least two operators and is relatively painful.
Il a été proposé, par FR-A-2 674 874, un dispositif autonome de pose de bandes autocollantes constitué par un châssis support d'un moyen de déroulement de bandes, par un rouleau d'application de la bande sur le sol, par un dispositif de transfert de la bande du moyen de déroulement vers le rouleau d'application, par un moyen de décollement et de récupération du film de protection de la face autocollante, par un dispositif de sectionnement de la bande et par un ensemble d'entraínement du châssis et des différents dispositifs et moyens de déroulement, de décollement, de récupération et de sectionnement de la bande à coller.It has been proposed, by FR-A-2 674 874, an autonomous laying device self-adhesive strips constituted by a support frame of a means of strip unwinding, by a roll of application of the strip on the ground, by a device for transferring the tape from the unwinding means to the roll application, by means of detachment and recovery of the film of protection of the self-adhesive side, by means of a sectioning device of the strip and by a drive unit of the chassis and the different devices and means of unwinding, detachment, recovery and sectioning of the tape to stick.
Dans ce dispositif, le rouleau d'entraínement de la bande est actionné par un ensemble d'entraínement comprenant un moyen d'embrayage commandé manuellement. Ainsi, l'opérateur doit constamment veiller et réguler la vitesse d'avancée de la bande en fonction de l'avancée de la machine, une vitesse relative trop importante de ladite bande entraínant un bourrage, une vitesse relative trop faible entraínant, en revanche, une tension élevée sur ladite bande et donc une détérioration de cette dernière pouvant aller de l'étirement jusqu'à la rupture de ladite bande à poser.In this device, the drive roller of the belt is actuated by a drive assembly comprising controlled clutch means manually. Thus, the operator must constantly watch and regulate the speed advance of the belt according to the advance of the machine, a relative speed too much of said strip causing a jam, a relative speed too much low drive, however, a high voltage on said band and therefore a deterioration of the latter, ranging from stretching to breaking said band to ask.
Dans le document FR-A-2 674 874, il est indispensable d'arrêter l'avancement du dispositif de pose lors de chaque coupe de la bande, ce qui en ralentit la pose. De plus, pour chaque phase d'arrêt et de redémarrage dudit dispositif, l'opérateur doit veiller à adapter la vitesse d'entraínement de la bande à celle de la machine, ce qui est particulièrement délicat et fastidieux pour des coupes rapprochées.In the document FR-A-2 674 874, it is essential to stop the progress of the laying device during each cut of the band, which slows down the laying. Of Moreover, for each phase of stopping and restarting the said device, the operator must take care to adapt the drive speed of the belt to that of the machine, which is particularly delicate and tedious for close cuts.
Par ailleurs, le certificat d'utilité FR-A-2 723 753 divulgue un dispositif autonome de pose de bandes autocollantes du même type que ci-dessus en particulier pour le marquage de sols, caractérisé en ce qu'il comporte un châssis roulant articulé, dont la partie avant porte le rouleau de bande à dérouler, l'ensemble de déroulement de bande, le dispositif de sectionnement et le moyen d'application de la bande sur le sol, de sorte que l'ensemble de déroulement et d'application est orientable indépendamment de la partie arrière du châssis. Si ce dispositif est particulièrement adapté à la pose en courbes à rayon trés fermé, il n'en demeure pas moins qu'il présente les mêmes inconvénients que ceux du dispositif décrit dans FR-A-2674 874.Furthermore, the utility certificate FR-A-2 723 753 discloses a self-adhesive device for laying self-adhesive strips of the same type as above, in particular for the soil marking, characterized in that it comprises an articulated rolling chassis, of which the front part carries the unwinding roll of tape, the unwinding assembly of band, the disconnecting device and the means for applying the band on the ground, so that the set of unwind and application is steerable regardless of the rear part of the chassis. Although this device is particularly suitable for laying curves with very closed radius, the fact remains that it has the same disadvantages as those of the device described in FR-A-2674 874.
Le marquage des sols en bandes préfabriquées est actuellement en pleine évolution, tant au niveau des colles que des structures même des bandes que l'on pose. Les performances sans cesse améliorées des colles font que l'on assiste actuellement à un retour aux bandes directement collées au détriment des bandes auto-adhésives qui nécessitent des machines plus complexes, donc plus chères et plus difficiles à mettre en oeuvre et à entretenir. Les exigences toujours croissantes en matière de vitesse d'application et de qualité de marquage font que les machines actuellement disponibles sur le marché ne sont plus adaptées voire complètement obsolètes.The marking of prefabricated strip flooring is currently in progress full evolution, both in the glues and the structures of the bands that we pose. The constantly improved performance of the glues make that one is currently witnessing a return to the directly glued tapes at the expense of self-adhesive tapes that require more complex machines, so more expensive and more difficult to implement and maintain. The requirements always growing in speed of application and quality of marking the machines currently available on the market are no longer adapted completely obsolete.
La présente invention a pour objet de palier les inconvénients des dispositifs précités et de fournir un dispositif autonome pour la pose de bandes préfabriquées en particulier pour le marquage des sols permettant des vitesses d'application beaucoup plus élevées et donc une réduction importante du temps pendant lequel les tronçons de route en construction ou en rénovation sont bloqués. A titre indicatif, et sans qu'il s'agisse ici d'une quelconque limitation, un dispositif d'application de bandes conforme à la présente invention peut atteindre jusqu'à 4 km/h pour des bandes continues, une vitesse encore jamais atteinte en déroulement et pose de bandes préfabriquées. De plus, une ouverture au trafic routier est possible dès que le marquage est fini et ce, que le marquage soit provisoire ou permanent. Un autre avantage du dispositif de la présente invention est qu'il procure en même temps une qualité de marquage (rectitude) et un confort d'application largement supérieurs à ceux des machines connues.The present invention aims to overcome the disadvantages of the aforementioned devices and to provide an autonomous device for laying prefabricated strips, particularly for marking floors allowing much higher application speeds and therefore a reduction significant amount of time during which sections of road under construction or renovation are blocked. As an indication, and without here being any of limitation, a strip application device according to the present invention can reach up to 4 km / h for continuous tapes, a speed never before unrolling and laying of prefabricated strips. In addition, an opening road traffic is possible as soon as the marking is finished and that the marking is provisional or permanent. Another advantage of the device of the present invention is that it provides at the same time a quality of marking (straightness) and comfort widely superior to those of known machines.
La présente invention a pour objet un dispositif autonome de pose de
bandes, en particulier pour le marquage de sols, tel que décrit à la revendication 1.
Le ou les
moyen(s) de synchronisation utilisé(s) dans la présente invention consiste(nt) en
un arrangement de courroie(s), de poulie(s) et/ou de poulie(s) double(s) ou
analogue(s).The subject of the present invention is an autonomous device for laying
strips, in particular for marking floors, as described in
L'ensemble de déroulement de la bande est constitué par un axe fixe, un rouleau d'amenée, un tambour supérieur de traction coopérant avec au moins un axe porte-galets supérieur, entraíneur et séparateur, dont les galets sont réalisés sous la forme de galets ou de rouleaux à pointes ou à parties saillantes, ces pointes ou parties saillantes étant réalisées dans la masse ou rapportées et disposées en quinconce d'un galet ou rouleau à l'autre avec intersection de leurs génératrices.The unwinding assembly of the strip is constituted by a fixed axis, a feed roller, an upper traction drum cooperating with at least one an upper roller shaft, drive and separator, whose rollers are made in the form of pebbles or rollers with points or protruding parts, these points or protruding parts being made in the mass or reported and arranged in staggered from one roller or roller to another with intersection of their generators.
Dans un mode de réalisation préférentiel, le dispositif selon l'invention comporte, en outre, un moyen de redressage de la bande, par exemple, sous la forme d'un axe redresseur muni d'un rouleau redresseur. Ce moyen de redressage est alors parallèle à l'ensemble de déroulement et pourvu d'un ou de plusieurs moyen(s) de guidage permettant de régler le redressement, la largeur et le maintien de la bande. Le réglage du moyen de redressage est, de préférence, effectué par l'intermédiaire du ou des moyen(s) de guidage précité(s), en regard du ou des moyen(s) de serrage de l'axe porte-bobine. En particulier, on peut prévoir que le réglage du ou des moyen(s) de guidage du moyen de redressage est effectué de telle manière que la bande soit légèrement tendue sur l'axe redresseur du moyen de redressage.In a preferred embodiment, the device according to the invention further includes tape straightening means, for example, in the form of a rectifier axis provided with a rectifier roll. This means of straightening is then parallel to the unwinding assembly and provided with one or a number of guiding means for adjusting the straightening, the width and maintaining the band. The adjustment of the straightening means is preferably carried out by means of the aforementioned guiding means (s), opposite the or means (s) for clamping the spool pin. In particular, one can foresee the adjustment of the means (s) for guiding the straightening means is carried out in such a way that the strip is slightly stretched on the straightening axis of the means straightening.
En ce qui concerne le sectionnement de la bande à coller, celui-ci est réalisé par un dispositif de sectionnement permettant d'effectuer des coupes dites "à la volée".With regard to the cutting of the tape to be glued, this one is made by a cutting device for performing said cuts "on the fly".
Une coupe est dite "à la volée" lorsque celle-ci ce fait instantanément sans interrompre le défilement de la bande à couper.A cup is called "on the fly" when it is done instantly without interrupting the scrolling of the tape to be cut.
Le dispositif de sectionnement de la présente invention comprend une lame transversale réalisée dans un acier trempé d'une dureté bien définie.The sectioning device of the present invention comprises a transverse blade made of hardened steel with a well defined hardness.
Ladite lame glisse, pour sa coupe, entre des porte-glissières de guidage en étant actionnée, à son extrémité opposée au tranchant, par un vérin de sectionnement. Le vérin de sectionnement peut être un vérin pneumatique commandé par une électrovanne à déclenchement manuel ou automatique. Le vérin pneumatique est calculé de façon que sa puissance soit suffisamment élevée pour couper tous les types de bandes existants ou à venir. La course aller-retour du vérin est de préférence la plus petite possible. D'autre part, pour pouvoir couper une bande large et épaisse ou une bande fine et très malléable, il est avantageux de pouvoir régler le jeu existant entre la lame et la contre-lame ainsi que les angles d'affûtage pour que la coupe soit nette et précise.Said blade slides, for its cut, between the slide rails of being actuated, at its end opposite the cutting edge, by a cylinder of sectioning. The disconnecting cylinder can be a pneumatic cylinder controlled by a manual or automatic trigger solenoid valve. The pneumatic cylinder is calculated so that its power is sufficiently high to cut all types of existing or future tapes. The round trip of the cylinder is preferably the smallest possible. On the other hand, to be able to cut a wide and thick band or a thin band and very malleable, it is advantageous to ability to adjust the existing clearance between blade and counter blade and angles sharpening so that the cut is clean and precise.
La présence d'un rouleau redresseur empêche que la bande ne dévie vers la gauche ou vers la droite au moment de la coupe. En effet, ledit rouleau garde la bande parfaitement perpendiculaire au plan de coupe, ce qui donne des coupes parfaitement d'équerre.The presence of a straightening roll prevents the band from deviating left or right when cutting. Indeed, said roll keeps the band perfectly perpendicular to the cutting plane, which gives perfectly square cuts.
Comme on le détaillera plus loin, le dispositif de sectionnement comporte, en plus de la lame précitée, une contre-lame, ladite lame étant disposée perpendiculairement au plan de la bande entre l'ensemble de déroulement et le moyen d'application et coopère, pour le sectionnement, avec ladite contre-lame s'étendant sur un support parallèlement à ladite lame entre le tambour supérieur de l'ensemble de déroulement et le rouleau applicateur, de manière à produire une coupe instantanée sans arrêt de la machine.As will be detailed below, the disconnecting device comprises, in addition to the aforementioned blade, a counterblade, said blade being arranged perpendicular to the plane of the web between the unwind assembly and the means of application and cooperates, for cutting, with said counterblade extending on a support parallel to said blade between the upper drum of the unwinding assembly and the applicator roll, so as to produce a instant cut without stopping the machine.
Ce dispositif de "coupe à la volée" permet d'obtenir des vitesses d'application de la bande beaucoup plus importantes que celles qui sont possibles sur les appareils de l'état de la technique. Comme déjà évoqué, la lame et/ou la contre-lame sont en acier trempé, afin d'assurer une résistance mécanique suffisante des instruments de coupe ainsi qu'une qualité de coupe élevée et constante.This device of "cutting on the fly" makes it possible to obtain speeds application of the band much larger than those that are possible on the apparatuses of the state of the art. As already mentioned, the blade and / or the Counterblade are hardened steel, to ensure mechanical strength sufficient cutting tools as well as a high quality of cut and constant.
Le dispositif autonome de pose de bandes comporte, en outre, un pupitre de commande et d'affichage pour le pilotage de l'appareil. Ce pupitre sera décrit de manière détaillée plus loin et possède, en plus des organes habituels permettant de faire fonctionner l'appareil, un automate programmable de gestion de la pose de la bande. Le dispositif comportant un pupitre de commande et d'affichage possédant un automate programmable de gestion de la pose de la bande est caractérisé en ce que ledit pupitre comporte un organe de commande permettant de choisir entre trois manières d'effectuer la coupe, soit de manière manuelle, soit semi-automatique, soit automatique.The autonomous banding device further comprises a control panel and display for controlling the device. This desk will be described in detail later and has, in addition to the usual organs to operate the device, a programmable logic controller laying the tape. The device comprising a control console and display having a programmable automaton for managing the installation of the strip is characterized in that said panel comprises a control member allowing to choose between three ways to make the cut, either manual, either semi-automatic or automatic.
L'invention sera mieux comprise, grâce à la description ci-après, qui
se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif,
et expliqué avec référence aux dessins schématiques annexés, dans lesquels :
Conformément à l'invention et comme le montre plus
particulièrement la figure 1 des dessins annexés, le dispositif autonome de pose 1
de bandes 2, en particulier pour le marquage de sols, est essentiellement constitué
par un châssis roulant 3, un ensemble (non représenté) d'entraínement du châssis
et d'actionnement de différents dispositifs et moyens de déroulement de la bande
2, par un axe de pivotement 4 sur un rouleau d'appui sur châssis 4', un moteur 5.
de préférence thermique, un compresseur 6 d'alimentation des circuits
pneumatiques, une réserve d'air 7, un pont hydrostatique 8, un pupitre 9 de
commande et d'affichage muni des organes de commande 10 et relié à une source
d'énergie électrique telle qu'une batterie (non représentée).According to the invention and as shown more
particularly FIG. 1 of the attached drawings, the
La partie traction du dispositif autonome de pose 1 de bandes 2 peut
être réalisée, en fonction de l'ensemble d'entraínement, selon plusieurs modes
(autoporté, autotracté), le mode décrit ci-après, à titre d'exemple non limitatif,
étant un mode autotracté.The traction part of the self-
Comme le montre la figure 2, le trajet parcouru par la bande 2 va de
la bobine 11 jusqu'à son application sur le sol au niveau du rouleau applicateur 33.
La bobine 11 de stockage de la bande 2, montée sur un axe porte-bobine 12, est
placée dans un logement spécial sur le châssis. Le déroulement de la bande 2 peut
être réglé dans sa position et dans la tension de la bande qui défile par le biais de
moyens de serrage 13 réalisés sous la forme de flasques 14 ou analogues situés sur
l'axe porte-bobine 12.As shown in Figure 2, the path traveled by
La bande 2 est tirée, partie adhésive 2' vers le haut, dans le sens de
déroulement indiqué par la flèche en direction du moyen de redressage 15
constitué par un axe redresseur 16 muni d'un rouleau redresseur 17 situés juste
avant l'ensemble de déroulement 19. Comme le montre la figure 3, cet axe
redresseur 16 est monté de manière parfaitement parallèle à l'ensemble de
déroulement 19 entre des flancs 41 et 41' reliés entre eux par une traverse 36', la
rotation de la bande 2 autour de l'axe empêchant la détérioration de cette dernière
en supprimant au maximum le frottement au moment du défilement. Le rouleau
redresseur 17 est muni d'un, de préférence, de plusieurs moyens de guidage 18 tels
que des bagues, flasques ou analogues qui règlent et maintiennent le redressement,
la largeur et la position de la bande 2. Bien entendu, le réglage des ce ou ces
moyens de guidage 18 doit être fait sur le même alignement que les flasques 14
des moyens de serrage 13 de l'axe porte-bobine 12. Les moyens de guidage 18 du
rouleau redresseur 17 peuvent être fixés par des moyens de blocage 18' habituels
tels que, par exemple, des boulons ou vis moletés ou analogues.The
Il est également possible de prévoir plusieurs bobines 11 de bande 2
sur le porte-bobine 12, par exemple, pour réaliser un marquage de chaussé réalisé
sous la forme de deux lignes parallèles. Il convient alors d'ajouter des paires de
flasques 14 supplémentaires sur l'axe porte-bobine 12 ainsi que des paires de
guides supplémentaires sur l'axe redresseur 16. On peut ainsi faire dérouler
simultanément deux ou plusieurs bobines de bande et obtenir un marquage
parfaitement parallèle.It is also possible to provide
De plus, un positionnement symétrique des bobines 11 sur l'axe
porte-bobine 12 permettra également de réaliser un marquage symétrique, par
exemple, par rapport à l'axe médian de la chaussée.In addition, a symmetrical positioning of the
Au sortir de la bobine 11 de stockage, la bande 2 se trouve guidée et
redressée par l'axe redresseur 16, juste avant d'être introduite dans l'ensemble de
déroulement 19 de la bande 2 qui est notamment composé d'un rouleau d'amenée
20 réalisé, par exemple, en caoutchouc naturel ou en polyuréthanne, d'une série
d'axes porte-galets supérieurs 21, 22, 23 et d'un axe fixe 24 (figures 2 et 3). A cet
endroit, la bande est pincée entre le premier axe porte-galet supérieur 21 et le petit
rouleau d'amenée 20 monté en contact des galets à pointes de ce premier axe. La
combinaison du rouleau redresseur 17 avec le pincement continu entre l'axe porte-galet
supérieur 21 et le rouleau d'amenée 20 garantit que la bande 2 ne puisse pas
bouger latéralement, ni à gauche, ni à droite. Ces moyens associés à l'axe porte-bobine
12, également fixe sur le châssis, et les flasques 14, qui sont réglables,
notamment en largeur, et qui viennent serrer les flancs de la bobine 11 de
stockage, permettent de tenir la bande 2 toujours légèrement tendue sur l'axe
redresseur 16, les flasques 14 sur les flancs de la bobine empêchant celle-ci de
continuer à tourner au moment de la coupe sous l'effet d'inertie.At the exit of the
Comme le montrent notamment les figures 2 et 4, les galets des axes
porte-galets supérieurs 21, 22 et 23, entraíneurs et séparateurs, sont
avantageusement réalisés sous la forme de galets à pointes ou parties saillantes 25,
ces pointes ou parties saillantes 25, réalisées dans la masse ou rapportées pouvant
être vives ou légèrement cassées. La figure 4 montre que les galets des axes porte-galets
supérieurs 21, 22, 23 sont disposés en quinconce d'un galet à l'autre et avec
intersection de leurs génératrices 21', 22', 23' et qu'ils sont solidaires en rotation
entre eux par l'intermédiaire du moyen de synchronisation réalisé ici sous la forme
des poulies 21", 22", de la poulie double 23" et de la courroie souple supérieure 26.
L'axe 23 entraíne également, par le biais de la poulie double 23", de la poulie 31"
et de la courroie souple inférieure 26', l'axe porte-galet inférieur 31 qui entraíne à
son tour l'axe porte-galet inférieur 32 par l'intermédiaire des poulies 32", 32''' et
des courroies latérales 35 et 35'. Il est ainsi possible de réaliser un entraínement
parfait de la bande 2.As shown in particular in FIGS. 2 and 4, the rollers of the axes
Afin d'éviter tout risque de bourrage de la bande 2, notamment
lorsque celle-ci est coupée, et en particulier pour des produits tels que les bandes
aluminisées, les axes porte-galets inférieurs 31, 32 se trouvant juste au-dessous de
la lame 30, et qui sont, par ailleurs, réalisés de manière similaire aux axes porte-galets
supérieurs 21, 22, 23, sont donc également synchronisés en rotation avec
l'ensemble de déroulement 19 se trouvant au-dessus de la lame 30 par des moyens
de synchronisation similaires à ceux utilisés pour la synchronisation des axes
porte-galets supérieurs 21, 22, 23, à savoir, les poulies 31", 32", 32''', les courroies
souples 26, 26', et latérales 35, 35'. Une courroie 26' synchronise notamment le ou
les axe(s) porte-galets supérieur(s) 21, 22, 23 avec le ou les axe(s) porte-galet(s)
inférieur(s) 31, 32. les galets d'un ou des axe(s) porte-galets inférieur(s) 31, 32
pouvant entraíner l'extrémité avant ou frontale de la nouvelle portion de bande à
découper ce qui évite le bourrage (figure 3).In order to avoid any risk of jamming of the
La largeur de l'aménage de la bande 2 a été optimisée de manière à
avoir une surface, et donc un nombre de pointes ou de parties saillantes 25 des
galets plus importants permettant ainsi de réduire la pression exercée sur la bande
2. Ceci augmente considérablement la souplesse du déroulement, compte tenu du
fait que tous les axes qui portent les galets sont synchronisés en rotation, à
l'exception de l'axe fixe 24 et des axes de guidage 42, 43, 44 non entraínés. Les
galets des différents axes porte-galets sont préférentiellement montés en
quinconce et sont tour à tour entraíneurs-séparateurs, lorsque la bande passe sur
les galets à pointes ou parties saillantes 25. La synchronisation permet également
de diminuer la pression appliquée sur le vérin supérieur 36. Le confort
d'avancement de ce dispositif autonome de pose 1 de bandes 2 est accru par la
présence d'un pont hydrostatique 8 supplémentaire relié à un moteur 5 en vue de
son déplacement, ledit moteur 5 pouvant également entraíner un compresseur 6
destiné à fournir de l'air sous pression pour l'alimentation de différents organes
d'actionnement, par exemple, du type vérin 36, 40. Contrairement à une boíte de
vitesse dont les rapports sont constants, le pont hydrostatique 8 permet un
avancement du dispositif autonome de pose 1 de bandes 2 avec une souplesse
d'avancement contrôlée à tout instant.The width of the layout of the
Lors de la mise en place de la bande 2 dans l'ensemble de
déroulement 19, l'extrémité de la bande 2 est introduite entre les pointes ou parties
saillantes 25 des galets du premier axe porte-galet supérieur 21 et le rouleau
d'amenée 20, ces deux éléments étant montés en pression l'un contre l'autre.
L'utilisateur de la machine actionne alors le ou les organes de commande 10 du
pupitre 9 de commande et d'affichage qui conespond(ent) à l'amenée du vérin
supérieur 36 contre le tambour supérieur 27 d'entraínement. Les axes porte-galets
supérieurs 21, 22, 23 étant en contact avec ledit tambour supérieur 27, il suffit
alors à l'utilisateur de tourner manuellement, par l'intermédiaire de la molette 37,
le tambour supérieur 27, dans le sens désiré pour faire avancer ou reculer la bande
2 et ainsi la positionner. La bande 2 se trouve alors entraínée par les galets de l'axe
porte-galet supérieur 21 et en arrivant à l'axe porte-galet supérieur suivant 22,
celui-ci répète l'opération jusqu'à ce que la bande 2 se trouve au niveau de la
contre-lame 28 du dispositif de sectionnement 29. La bande 2 se trouve ainsi mise
en place au-dessous de l'axe porte-galet supérieur 23 où se trouve l'axe fixe 24
dont les galets sont montés libres et fous entre eux, ledit axe fixe étant monté,
solidaire du dispositif de sectionnement 29. entre les porte-glissières 49 et 49' de
la lame 30 (fig. 3).When setting up
Depuis le pupitre 9, l'opérateur déclenche la pose de la bande 2 par
un bouton électrique mettant l'automatisme en route : le rouleau applicateur 33 qui
se trouve au contact du sol, et dont le mouvement en rotation est synchronisé avec
le déplacement de la machine, synchronise en rotation le tambour supérieur 27 par
le biais de la courroie 38 et des poulies 27" et 33", la courroie 38 étant libre et non
tendue au repos. L'ensemble galet de tension-vérin 39 vient tendre, au moment du
déclenchement de la pose, la courroie 38, et provoque ainsi la rotation
synchronisée du tambour supérieur 27 et du rouleau applicateur 33 et par la même,
le défilement de la bande 2.From the desk 9, the operator triggers the laying of the
L'opérateur active alors, par l'intermédiaire des organes de
commande 10 du pupitre 9 d'affichage et de commande, l'automate programmable
de gestion de la pose de la bande 2, permettant de choisir entre trois manières
d'effectuer la coupe, soit de manière manuelle, soit semi-automatique, soit
automatique. Dans le mode manuel, l'opérateur provoque la coupe depuis le
pupitre 9; dans le mode semi-manuel, la pose suivante ne se fait que sur l'ordre de
l'opérateur, la coupe étant provoquée par une gestion électronique et dans le mode
automatique la gestion électronique répète un cycle de mesure de la longueur de la
bande 2, du vide à éventuellement laisser entre deux morceaux de bande 2
consécutifs et du déclenchement de la coupe.The operator then activates, via the
Comme on le voit sur les figures 2 et 3, le dispositif de
sectionnement 29 du dispositif autonome de pose 1 de bandes 2 est constitué par
une lame 30 transversale guidée entre les porte-glissières 49 et 49' et actionnée à
son extrémité opposée au tranchant par un vérin de sectionnement 40 monté sur
une traverse 40', ladite lame 30 étant disposée perpendiculairement au plan de la
bande 2 entre l'ensemble déroulement 19 et le moyen d'application 34 et coopère,
pour le sectionnement, avec ladite contre-lame 28 s'étendant sur un support 28'
parallèlement à la lame 30 entre le tambour supérieur 27 de l'ensemble de
déroulement 19 et le rouleau applicateur 33. de manière à produire une coupe
instantanée sans arrêt de la machine. Par ailleurs, cette coupe doit être effectuée de
manière assez rapide, afin que l'effet de mâchage ne vienne pas faire glisser la
bande 2 entre la lame 30 et la contre-lame 28, ce qui aurait comme conséquence
que la bande 2 ne serait pas coupée. Une vitesse de coupe satisfaisante pendant le
défilement de la bande 2 est obtenue par le bon choix de la puissance du vérin de
sectionnement 40, en optimisant son alimentation en air comprimé issu du
compresseur 6 et grâce à la réserve d'air 7 par le biais d'électro-distributeurs
commandés depuis le pupitre 9 de commande et d'affichage. A titre indicatif, la
pression de l'air comprimé est comprise entre environ 6 et 8 bars. Bien entendu, le
vérin de sectionnement 40 ainsi que les autres vérins employés dans la présente
invention peuvent aussi être actionnés de manière hydraulique ou d'une manière
équivalente. Afin de garantir une coupe de qualité élevée et constante, la lame 30
et/ou la contre-lame 28 est/sont préférentiellement réalisée(s) en acier trempé, la
lame 30 étant déplacée par le vérin de sectionnement 40.As can be seen in FIGS. 2 and 3, the device for
sectioning 29 of the
On note également sur les figures 2 et 3 que le rouleau d'amenée 20,
l'axe fixe 24 et les axes porte-galets supérieurs 21, 22, 23 sont montés sur un
châssis pivotant, compris entre deux flancs 47, 47' reliés par une traverse 48.It is also noted in FIGS. 2 and 3 that the
Ledit châssis pivotant est articulé autour de l'axe porte-galet
supérieur 23 et positionné par un vérin supérieur 36, l'application des galets
desdits axes porte-galets supérieurs 21, 22, 23 sur la bande 2, contre le tambour
supérieur 27 de traction et la contre-lame 28, étant réglable par l'intermédiaire du
pupitre 9 de commande et d'affichage. Les flancs 47 et 47' maintiennent tous ces
organes parfaitement parallèles entre eux dans un arrangement compact encore
appelé tête de pose qui est délimité par les parois latérales 41 et 41' et qui se relie
au châssis roulant 3 par des pivots oscillants autour de l'axe 23. De cette manière,
la tête de pose peut osciller (pivoter) autour dudit axe 23, ce dernier traversant
l'ensemble de part en part et se logeant dans des roulements montés sur les parois
latérales 41, 41' en étant positionné par le vérin supérieur 36 fixé sur la traverse
36' elle-même fixée sur lesdites parois latérales 41, 41' par des moyens classiques
connus de l'homme du métier. Ce montage a pour avantage, lorsque la bande 2
passe sous le rouleau applicateur 33, de permettre à la tête de pose d'effectuer une
légère oscillation vers le haut, le reste de la machine restant parfaitement stable, ce
qui assure une rectitude de pose parfaite de la bande 2 sur le.sol.Said pivoting frame is articulated around the roller holder axis
upper 23 and positioned by an
Comme on le voit très clairement sur les figures 2 et 3, la bande 2
passe, dans son avancement, entre la lame 30 et la contre-lame 28 et sous les axes
porte-galets inférieurs 31 et 32 qui sont entraínés en rotation par la poulie 31"
montée sur l'axe porte-galet inférieur 31 et reliés entre eux par les courroies
latérales 35, 35', l'axe 31 étant entraíné à son tour par les courroies souples
supérieure et inférieure 26, 26' mues par les axes porte-galets supérieurs 21, 22,
23. Les galets (non tous représentés) des deux axes porte-galets inférieurs 31 et 32
sont aussi montés en quinconce entre eux, les axes précités étant montés sur des
roulements étanches comme le sont préférentiellement tous les axes tournants de
la présente invention. La bande 2 continue son acheminement et arrive au moyen
d'application 34 de la bande 2 sur le sol, essentiellement constitué par au moins un
axe porte-galets inférieur 31, 32, au moins un axe de guidage 42, 43, 44 et le
rouleau applicateur 33 qui peut être un deuxième tambour entraíneur. Le ou les
axe(s) de guidage 42, 43 et 44 sont monté(s) fixe(s) en avant du rouleau
applicateur 33, vu dans le sens de la marche, entre les pièces latérales de support
50 et 50' et possèdent des galets (non tous représentés) qui tournent, libres et fous,
entre des circlips (non représentés). Passée sous l'axe 44, la bande 2 touche le sol
et le dispositif autonome de pose 1, en avançant, fait que le rouleau applicateur 33
puisse happer l'extrémité de la bande 2 qu'il fait passer sous lui. Ainsi, la bande 2,
amenée par l'ensemble de déroulement 19 est parfaitement guidée et appliquée sur
le sol.As can be seen very clearly in Figures 2 and 3,
Le moyen d'application 34 de la bande 2 est en liaison d'entraínement
avec l'ensemble de déroulement 19 par l'intermédiaire d'une courroie 38 montée
entre les poulies 27" et 33" prévues respectivement sur le tambour supérieur 27 de
traction et l'arbre du rouleau applicateur 33. l'ensemble galet de tension-vérin 39
jouant le rôle d'un embrayage en tendant la courroie 38 en service. L'ensemble
galet de tension-vérin 39 peut être constitué, comme le montre la figure 2 des
