Abstract

The corrugating machine comprises a series of corrugating bars (6) fixed to a driven endless chain (5), and a series of supporting bars (13) for the material (10) being corrugated. The corrugating bars are able to move relative to the endless chain, their movements being perpendicular to the plane of the supporting bars. The supporting bars have additional bars beneath them on a second endless chain to hold them up while a pressure is applied by the corrugating bars and acting at the same time as drying elements.

Description

L'invention est relative à une machine pour l'obtention de matériaux profilés, à partir de feuilles en une matière malléable, telle que par exemple, du carton humide ou du feutre.The invention relates to a machine for obtaining profiled materials, from sheets of material malleable, such as wet cardboard or felt.

Le profil du matériau est généralement de type sinusoïdal, des zones plates pouvant éventuellement alterner avec des ondulations.The profile of the material is generally of the type sinusoidal, flat areas possibly alternate with ripples.

Ce matériau est utilisé pour réaliser des couvertures et, plus particulièrement, des sous-toitures pour des toits en tuiles canal ou plates.This material is used to make blankets and, more particularly, sub-roofs for roofs in canal or flat tiles.

On connaít déjà des machines permettant d'onduler des feuilles en matière souple, défilant de manière continue, les ondulations étant réalisées sensiblement perpendiculairement au sens de défilement des feuilles.We already know machines for waving sheets of flexible material, continuously scrolling, the undulations being produced substantially perpendicular to the direction of travel of the sheets.

Ainsi, le brevet FR-2 079 499 décrit une machine à onduler comportant deux arbres parallèles et entraínés en rotation en sens opposés. Sur ces arbres, sont fixées des bras porteurs de barres ondulatrices, les barres étant parallèles aux arbres. Par ailleurs, deux tapis sans fin sont aménagés pour pincer entre eux la feuille en matière souple et l'amener au point d'interpénétration maximale des barres ondulatrices.Thus, patent FR-2 079 499 describes a undulate comprising two parallel shafts and driven in rotation in opposite directions. On these trees, are fixed arms of corrugating bars, the bars being parallel to the trees. In addition, two endless carpets are arranged to pinch the sheet between them flexible and bring it to the point of maximum interpenetration of waving bars.

Lorsqu'elle est insérée entre les barres ondulatrices de chaque arbre, la feuille souple prend une forme ondulée, la profondeur des ondes dépendant de l'espacement des arbres.When inserted between the wavy bars of each tree, the flexible sheet takes a wavy shape, the depth of the waves depending on the spacing of trees.

On peut également citer un autre type d'ondulatrice, dans lequel les ondulatrices sont portées par des étriers, solidaires d'une chaíne sans fin. Les barres ondulatrices sont ainsi entraínées par la chaíne sans fin qui est, en partie, parallèle au plan de défilement des feuilles en matière souple. Celles-ci sont portées par les barres espacées du séchoir qui assurent leur défilement et qui sont perpendiculaires à leur direction de défilement. We can also cite another type of inverter, in which the inverters are carried by stirrups, attached to an endless chain. Waving bars are thus entrained by the endless chain which is, in part, parallel to the sheet scrolling plane in flexible material. These are carried by the bars spaced from the dryer which ensures their scrolling and which are perpendicular to their direction of travel.

La chaíne sans fin est entraínée par au moins deux arbres parallèles aux barres du séchoir.The endless chain is driven by at least two trees parallel to the dryer bars.

Lorsqu'une barre ondulatrice arrive en regard d'une feuille en matériau souple, elle s'engage dans l'espace vide ménagé entre deux barres du séchoir. La barre ondulatrice reste en contact avec la feuille souple tant qu'elle est parallèle au plan du séchoir, puis, entraínée par la chaíne sans fin, elle se dégage des barres du séchoir. La feuille souple prend ainsi une forme ondulée. La profondeur des ondes dépend de l'écart de niveau entre les arbres entraínant la chaíne sans fin et les barres du séchoir.When a wavy bar arrives next to a sheet of flexible material, it engages in space vacuum created between two bars of the dryer. Bar corrugator stays in contact with the flexible sheet as long that it is parallel to the plane of the dryer, then, driven by the endless chain, it emerges from the bars of the dryer. The flexible sheet thus takes a wavy shape. The depth of the waves depends on the level difference between the trees driving the endless chain and the bars of the dryer.

On connaít encore la demande de brevet japonais JP-60 115 332 qui décrit une machine de formage d'ailettes de radiateur. Lors de la formation de ces ailettes métalliques, des têtes, portées par une bande sans fin, viennent au contact de la bande de métal plane pour y former des ondulations. Lors de contact, les têtes sont animées d'un mouvement de rotation par rapport à la bande et plusieurs ondulations sont formées simultanément.We still know the Japanese patent application JP-60 115 332 which describes a fin forming machine radiator. During the formation of these fins metallic, heads, carried by an endless band, come into contact with the flat metal strip to form ripples. When in contact, the heads are rotated relative to the web and several undulations are formed simultaneously.

Ces ondulatrices sont utilisées depuis de nombreuses années et elles ont apporté satisfaction.These inverters have been used for many years and they have brought satisfaction.

Cependant, la conception des ondulatrices connues limite la profondeur des ondes. En effet, si les deux systèmes de barres sont trop rapprochés, ils ne peuvent pénétrer l'un dans l'autre, ni à l'engagement, ni au dégagement des barres ondulatrices. La machine ne peut pas fonctionner.However, the design of known inverters limits the depth of the waves. Indeed, if the two bar systems are too close together, they cannot penetrate one into the other, neither to the engagement nor to the release of the waving bars. The machine cannot function.

En outre, l'expérience a montré qu'en défilement continu, les ondulations doivent être réalisées les unes après les autres et non simultanément, ce qui limite les valeurs supérieures des rayons de courbure des parties de retour des chaínes. Furthermore, experience has shown that while scrolling continuous, the undulations must be made one after the others and not simultaneously, which limits the higher values of the radii of curvature of the parts of return of the chains.

Or, il est apparu nécessaire d'obtenir des matériaux profilés présentant des ondulations relativement profondes et rapprochées. La résistance au fléchissement de tels matériaux est augmentée par rapport à des matériaux profilés classiques. Ceci permet d'accroítre la solidité des toitures dans lesquelles ils sont utilisés.However, it appeared necessary to obtain materials profiles with relatively deep undulations and close together. The resistance to deflection of such materials is increased compared to materials classic profiles. This increases the solidity roofs in which they are used.

De plus, les matériaux à ondulations profondes sont mieux adaptés au calage des tuiles dans certaines applications.In addition, deep corrugated materials are better suited for setting tiles in some applications.

Une nouvelle machine ondulatrice a donc été conçue pour obtenir des matériaux présentant un profil de type sinusoïdal et, en particulier, un profil marqué avec des ondulations profondes.A new inverter machine has therefore been designed to obtain materials with a type profile sinusoidal and, in particular, a profile marked with deep ripples.

L'invention est ainsi relative à une machine ondulatrice telle que définie par la revendication 1.The invention thus relates to a machine inverter as defined by claim 1.

Ainsi, lorsqu'une barre ondulatrice arrive en regard des barres de support, elle subit un mouvement de translation perpendiculairement au plan des barres de support et vient s'enfoncer entre deux barres de support.So when a wavy bar comes next support bars, it undergoes a movement of translation perpendicular to the plane of the bars of support and is inserted between two support bars.

La profondeur des ondes dépend de l'amplitude du mouvement de translation, qui est imprimé aux barres ondulatrices. The depth of the waves depends on the amplitude of the translational movement, which is printed on the bars corrugating.

Elle n'est limitée que par la résistance du matériau à onduler qui est constitué généralement d'une feuille en matière souple. En effet, même si une barre ondulatrice pénètre profondément entre deux barres de support, elle peut facilement s'en dégager grâce à un mouvement en translation, perpendiculaire au plan des barres de support du matériau à onduler.It is only limited by the material's resistance to waving which is usually made of a sheet in flexible material. Indeed, even if a wavy bar penetrates deeply between two support bars, it can easily be released thanks to a movement in translation, perpendicular to the plane of the support bars of the material to be corrugated.

Par ailleurs, la machine permet de réaliser les ondes les unes après les autres.In addition, the machine makes it possible to carry out the waves one after the other.

En référence à la figure 1, la machine selon l'invention comprend un bâti 1 dans lequel sont montées les barres ondulatrices 6.Referring to Figure 1, the machine according to the invention comprises a frame 1 in which are mounted the wave bars 6.

Le matériau à onduler 10 provient d'un système non représenté sur la figure. Il est guidé par des moyens appropriés 11 et 12 sur les barres 13 de la chaíne 14 du séchoir.The material to be corrugated 10 comes from a non-system shown in the figure.

Il est généralement constitué par une feuille de matière malléable telle que carton humide ou feutre.It generally consists of a sheet of malleable material such as wet cardboard or felt.

En sortie de la machine à onduler, le matériau profilé est amené à l'entrée du séchoir tunnel 16. Quand il sort du séchoir, le matériau profilé est retiré des barres du séchoir. Le sens de la circulation du matériau sur la chaíne 14 du séchoir est indiqué par la flèche F.At the outlet of the corrugating machine, the profiled material is brought to the entrance of tunnel dryer 16.

This limits the risks of product deterioration and reduces the costs of Implementation.

Dans le bâti 1, sont montés deux paliers 2. Chacun des paliers est traversé par un arbre 3 entraíné en rotation par un moteur non représenté sur La figure. Les arbres 2 sont parallèles et entraínent en rotation une chaíne sans fin 5, par l'intermédiaire d'organes de transmission 45.In frame 1, two bearings are mounted 2. Each of the bearings is crossed by a shaft 3 driven in rotation by a motor not shown in the figure. Trees 2 are parallel and drive in rotation a chain without end 5, via transmission elements 45.

De préférence, l'ensemble constitué par la chaíne sans fin 5 et les barres ondulatrices 6 est fixé sur un bâti intermédiaire 8, lui-même fixé au bâti 1. Le bâti intermédiaire est monté coulissant sur des glissières. Preferably, the assembly constituted by the chain without end 5 and the waving bars 6 is fixed on a frame intermediate 8, itself fixed to the frame 1.

En référence à la figure 2, la feuille 10 de matériau à onduler est supportée par les barres 13 de la chaíne du séchoir. Elle est transformée entre les barres ondulatrices 6 et les barres 13. Le matériau 21 qui sort de la machine à onduler présente le profil correspondant à la machine et au réglage des barres ondulatrices. Il est également illustré à la figure 4.With reference to FIG. 2, the sheet 10 of material to be waving is supported by the bars 13 of the chain of dryer. It is transformed between the waving bars 6 and the bars 13. The material 21 which leaves the machine waving presents the profile corresponding to the machine and adjustment of the waving bars. It is also illustrated in Figure 4.

Dans l'exemple illustré à la figure 2, la machine à onduler comporte, en alternance, deux barres ondulatrices 6 de section ronde et une tige de maintien 22. Comme on le verra ultérieurement, les tiges de maintien permettent de former des zones plates. Le matériau 21 comporte ainsi une alternance de deux ondulations 23 et d'une zone plate 24.In the example illustrated in Figure 2, the waving comprises, alternately, two waving bars 6 of round section and a retaining rod 22. As is will see later, the holding rods allow form flat areas. The material 21 thus comprises a alternation of two undulations 23 and a flat area 24.

Lorsque le matériau profilé est utilisé en tant que sous-toiture pour une toiture en tuiles canal, les zones plates permettent de bien caler les tuiles de courant ou les tuiles de couvert si les tuiles de courant sont supprimées.When the profiled material is used as roofing for a canal tile roof, the zones plates allow the current tiles to be properly wedged or cover tiles if the current tiles are deleted.

La figure 3 illustre de façon plus précise comment les barres ondulatrices sont reliées à la chaíne sans fin. Figure 3 illustrates more precisely how waving bars are connected to the endless chain.

Pour pouvoir profiler des feuilles de taille importante, des barres ondulatrices sont relativement longues. C'est pourquoi, la chaíne sans fin est, de préférence, constituée de deux éléments 25, reliés par des barres de support 26.To be able to profile size sheets important, wavy bars are relatively long. This is why, the endless chain is, from preferably made up of two elements 25, connected by support bars 26.

Le support 7 de chaque barre ondulatrice 6 sur une barre de support 26 comporte : au moins un élément 27 traversant un organe de guidage 33 fixé à la barre 26, l'élément 27 étant mobile en translation par rapport à la barre 26 et à l'organe de guidage 33 et perpendiculairement à ceux-ci, et un système 28 de support de la barre ondulatrice 6, relié à l'élément 27 par des moyens appropriés 29.The support 7 of each corrugator bar 6 on a support bar 26 comprises: at least one element 27 passing through a guide member 33 fixed to the bar 26, the element 27 being movable in translation relative to the bar 26 and to the guide member 33 and perpendicularly to them, and a bar support system 28 inverter 6, connected to element 27 by means appropriate 29.

Le système de support est nécessaire lorsque la barre ondulatrice est relativement longue.The support system is necessary when the bar wave is relatively long.

De préférence, est également prévu dans ce cas un système 41 de reprise d'efforts. Un élément mobile 27 est alors prévu de part et d'autre du système de reprise d'efforts.Preferably, there is also provided in this case a effort recovery system 41. A movable element 27 is then provided on both sides of the recovery system effort.

Du côté opposé à la barre ondulatrice 6, est fixé sur l'élément mobile 27 une chape 30 supportant un élément 31, entre deux roulements 32. L'élément 31 est légèrement en saillie par rapport aux deux roulements.On the side opposite the corrugator bar 6, is fixed on the movable element 27 a yoke 30 supporting an element 31, between two bearings 32. The element 31 is slightly in protrusion from the two bearings.

La chape 30 est reliée à l'organe de guidage 33 par des moyens élastiques 34, tels qu'un ressort.The yoke 30 is connected to the guide member 33 by elastic means 34, such as a spring.

En référence de nouveau à la figure 2, la machine à onduler comporte également au moins deux cames 35, entraínées en rotation par un arbre 36. Chaque came 35 comporte une pluralité de saillies 40. On prévoit autant de cames que d'éléments 27 pour une barre ondulatrice. L'arbre 36 est porté par le bâti 1 et entraíné par un moteur non représenté sur les figures.Referring again to Figure 2, the machine waving also includes at least two cams 35, rotated by a shaft 36. Each cam 35 has a plurality of projections 40. There are as many cams as of elements 27 for a wave bar. The tree 36 is carried by the frame 1 and driven by a non-motor shown in the figures.

Dans le bâti 1, est fixée une glissière 37 comportant une première zone 38 parallèle au plan des barres 13 du séchoir et une deuxième zone 39 en biais, s'écartant de ce plan. On prévoit autant de glissières que de cames.In the frame 1, is fixed a slide 37 comprising a first zone 38 parallel to the plane of the bars 13 of the dryer and a second area 39 at an angle, deviating from this plan. There are as many slides as there are cams.

Le fonctionnement de la machine ondulatrice est alors le suivant :The operation of the inverter machine is then the following :

La feuille 10 de matériau à onduler est fournie en continu et vient se placer sur les barres 13 du séchoir qui défilent également en continu sur la chaíne 14 du séchoir.The sheet 10 of material to be corrugated is supplied in continuous and is placed on the bars 13 of the dryer which also run continuously on the chain 14 of the dryer.

Une barre ondulatrice 6 est amenée par la chaíne sans fin 5 dans la partie 42 de la chaíne 5 où elle est en regard du plan des barres de support. Le support 7 de la barre ondulatrice est alors perpendiculaire au plan des barres 13 du séchoir. La barre ondulatrice se trouve en position haute et n'est pas en contact avec le matériau à onduler. Elle vient alors en regard d'une saillie 40 de la came, qui vient en appui sur l'élément 31.A waving bar 6 is brought by the chain without end 5 in part 42 of chain 5 where it is in look at the support bar plan. Support 7 of the wavy bar is then perpendicular to the plane of bars 13 of the dryer. The wavy bar is in high position and is not in contact with the material to be waving. It then comes next to a projection 40 of the cam, which bears on element 31.

Dans l'exemple illustré sur les figures, cette partie 42 de la chaíne est parallèle au plan des barres de support et les barres ondulatrices sont fixées orthogonalement à la chaíne, mais cet exemple n'est pas limitatif. D'autres modes de réalisation peuvent être envisagés, dans lesquels le mouvement des barres ondulatrices s'effectue également perpendiculairement au plan des barres de support, dans la partie 42 de la chaíne.In the example illustrated in the figures, this part 42 of the chain is parallel to the plane of the support bars and the wavy bars are fixed orthogonally to the chain, but this example is not limitative. other embodiments can be envisaged, in which the movement of the waving bars is also carried out perpendicular to the plane of the support bars, in the part 42 of the chain.

Du fait de la rotation de la came 35, la saillie 40 enfonce l'élément mobile 27 du support de la barre ondulatrice. La barre ondulatrice subit alors une translation, perpendiculairement au plan de La chaíne sans fin et à celui des barres de support et se trouve en position basse.Due to the rotation of the cam 35, the projection 40 presses the movable element 27 of the bar support Corrugating. The corrugator bar then undergoes a translation, perpendicular to the plane of the chain without end and that of the support bars and is in low position.

Le déplacement de la chaíne 5 des barres ondulatrices et celui de la chaíne 14 du séchoir sont réglés l'un par rapport à l'autre, de façon à ce qu'une barre ondulatrice soit placée en position basse entre deux barres du séchoir. The displacement of the chain 5 of the waving bars and that of the chain 14 of the dryer are regulated one by relative to each other, so that a wavy bar is placed in the low position between two bars of the dryer.

Le mouvement de la chape 30 comprime les moyens élastiques 34 qui se trouvent dans la position illustrée à la figure 3.The movement of the yoke 30 compresses the means elastic bands 34 which are in the position illustrated in Figure 3.

Avant que le contact entre l'élément 31 du support de la barre ondulatrice et la saillie 40 ne prenne fin du fait du mouvement de rotation de la came 35, les roulements 32 viennent en contact avec la glissière 37, la barre ondulatrice étant entraínée par la chaíne sans fin 5 dans la direction de défilement du matériau à onduler.Before contact between element 31 of the support the wave bar and the projection 40 do not end because of the rotational movement of the cam 35, the bearings 32 come into contact with slide 37, the bar inverter being driven by the endless chain 5 in the direction of travel of the material to be corrugated.

La barre ondulatrice 6 est ainsi maintenue en position basse tant que les roulements 32 sont en contact avec la première zone 38 de la glissière, parallèle au plan des barres 13 du séchoir.The corrugator bar 6 is thus held in position low as long as the bearings 32 are in contact with the first zone 38 of the slide, parallel to the plane of the bars 13 of the dryer.

Ensuite, les roulements 22 s'engagent dans la deuxième zone 39 de la glissière. En sortie de cette deuxième zone, la barre ondulatrice 6 se trouve de nouveau en position haute.Then, the bearings 22 engage in the second zone 39 of the slide. On leaving this second zone, the corrugator bar 6 is again in position high.

La pression sur l'élément 31 se relâchant, le ressort 34, préalablement comprimé, se détend. L'élément mobile 27 subit alors un mouvement de translation qui l'éloigne du plan des barres 13 du séchoir. Le mouvement entraíne la remontée de la barre ondulatrice qui se trouve dégagée des barres du séchoir entre lesquelles elle pénétrait.The pressure on the element 31 is released, the spring 34, previously compressed, relaxes. The moving element 27 then undergoes a translational movement which moves it away from the plan of the bars 13 of the dryer. The movement is rise of the corrugator bar which is clear of bars of the dryer between which it penetrated.

La barre ondulatrice est ensuite entraínée par la chaíne sans fin.The corrugator bar is then driven by the endless chain.

Les positions de la came 35 et de la glissière 37 sont, de préférence, choisies de façon à maintenir les barres ondulatrices 6 en contact avec le matériau à onduler, tant que la chaíne 5 est parallèle au plan des barres du séchoir.The positions of the cam 35 and of the slide 37 are, preferably chosen to maintain the bars corrugators 6 in contact with the material to be corrugated, both that the chain 5 is parallel to the plane of the bars of the dryer.

Ceci permet d'escamoter facilement les barres ondulatrices dont le support est perpendiculaire au plan du séchoir, tout en maintenant suffisamment longtemps les barres ondulatrices en contact avec le matériau à onduler pour former le profil de façon stable et diminuer les contraintes.This allows the bars to be easily retracted undulators whose support is perpendicular to the plane of the dryer, while keeping the corrugating bars in contact with the material to be corrugated to form the profile stably and decrease constraints.

La machine à onduler représentée à la figure 1 comporte, en alternance, deux barres ondulatrices 6 et une tige de maintien 22.The corrugator shown in Figure 1 alternately comprises two waving bars 6 and one retaining rod 22.

La tige de maintien est fixée à la chaíne sans fin 5 par un support 43, de façon à se trouver en contact avec le matériau à onduler sans pénétrer entre les barres du séchoir.The retaining rod is fixed to the endless chain 5 by a support 43, so as to be in contact with the material to be corrugated without penetrating between the bars of the dryer.

La tige 22 permet d'éviter que le matériau à onduler ne se déforme, du fait de l'enfoncement des barres ondulatrices, de part et d'autre de la tige de maintien. Le matériau 21 obtenu présente ainsi des zones plates et non bombées.The rod 22 makes it possible to prevent the material to be corrugated from deforms, due to the depression of the bars undulating, on either side of the holding rod. The material 21 obtained thus has flat areas and not bulged.

Un matériau de profil différent peut être obtenu en modifiant la chaíne sans fin et notamment en modifiant l'alternance de barres ondulatrices et de tiges de maintien ou en supprimant les tiges de maintien.A different profile material can be obtained by modifying the endless chain and in particular by modifying alternating waving bars and holding rods or by removing the holding rods.

La profondeur des ondes est réglée en positionnant de façon appropriée la chaíne sans fin par rapport aux barres du séchoir.The depth of the waves is adjusted by positioning appropriately the endless chain in relation to the bars of the dryer.

Enfin, les ondulations obtenues ne sont pas nécessairement sinusoïdales. En modifiant la section des barres ondulatrices, on peut obtenir par exemple des ondes de type grec ou des ondes en V.Finally, the undulations obtained are not necessarily sinusoidal. By modifying the section of wave bars, you can get waves for example Greek type or V waves.

En référence à la figure 5, un mode préféré de réalisation de la machine à onduler selon l'invention va maintenant être décrit.Referring to Figure 5, a preferred mode of realization of the corrugating machine according to the invention will now be described.

Lors de la formation du matériau ondulé, les barres ondulatrices pénètrent entre les barres du séchoir et des efforts importants sont exercés sur les barres du séchoir.During the formation of the corrugated material, the bars undulators penetrate between the bars of the dryer and significant efforts are exerted on the bars of the dryer.

Pour éviter toute déformation des barres du séchoir et toute détérioration à terme de la machine, on prévoit des barres de renfort 20. To prevent deformation of the dryer bars and any deterioration over time of the machine, reinforcement bars 20.

Ces barres 20 sont fixées sur la chaíne sans fin 17, entraínée en rotation par les arbres 18, par l'intermédiaire des organes de transmission 46.These bars 20 are fixed on the endless chain 17, driven in rotation by the shafts 18, by through the transmission organs 46.

La chaíne sans fin 5 est synchronisée avec la chaíne 14 du séchoir de façon à ce qu'une barre de soutien 20 vienne au contact d'une barre 13 du séchoir, lorsque celle-ci se trouve dans la zone où le matériau est profilé. La barre de soutien reste, de préférence, en contact avec la barre du séchoir tant que la chaíne 5 des barres ondulatrices est parallèle au plan des barres du séchoir et que des barres ondulatrices sont donc présentes entre deux barres du séchoir.The endless chain 5 is synchronized with the chain 14 of the dryer so that a support bar 20 comes in contact with a bar 13 of the dryer, when the latter found in the area where the material is profiled. The bar support preferably stays in contact with the bar dryer as long as the chain 5 of the corrugator bars is parallel to the plane of the dryer bars and that bars undulators are therefore present between two bars of the dryer.
