DESCRIPTION
Etat de la technique Depuis 50 ans et l'arrivée dans le monde agricole des premières enrouleuses pour la paille, il y a eu beaucoup d'évolution dans les techniques d'enroulage et de nombreux brevets ont été déposés. Dans le monde industriel, quelques brevets ont été déposés pour résoudre les problèmes posés par l'enroulage des matières. Ainsi, l'enroulage des matières fibreuses, et notamment du lin, a donné lieu à un brevet. Les revendications de procédé exposées dans ce brevet sont sujettes à critiques en raison d'une antériorité notoire et bien connue des professionnels : le projet était déjà connu par l'ensemble de la profession dans les années 1985. DESCRIPTION
State of the art For 50 years and the arrival in the agricultural world of the first winders for straw, there have been many developments in winding techniques and many patents have been filed. In the industrial world, some patents have been filed to solve the problems posed by the winding of materials. Thus, the winding of fibrous materials, and in particular linen, gave rise to a patent. The process claims set out in this patent are subject to criticism due to a well-known and well-known prior art: the project was already known by the entire profession in the years 1985.
Les revendications de dispositif font état de bords francs et de la position d'au moins un lien continu placé sous la nappe de fibre pour permettre de séparer les spires lors du déroulage. The device claims state clear edges and the position of at least one continuous link placed under the sheet of fiber to allow the turns to be separated during unwinding.
La matière pénètre dans la machine et les bords latéraux en forme d'entonnoir du dispositif mécanique limitent progressivement la largeur des fibres qui se replient vers l'arrière. Au fond de l'entonnoir, les deux plaques métalliques latérales et parallèles limitent la largeur de la balle et constituent les bords francs de la matière ainsi conditionnée. The material enters the machine and the funnel-shaped lateral edges of the mechanical device progressively limit the width of the fibers which fold back. At the bottom of the funnel, the two lateral and parallel metal plates limit the width of the bale and constitute the clean edges of the material thus conditioned.
De cette conception, il découle plusieurs problèmes liés au dispositif ainsi qu'au procédé. Le premier est lié à la présence des flancs métalliques destinés à imposer des bords francs à la matière pressée. La matière fibreuse reste d'une manière permanente au contact de ces parties métalliques et est donc en permanence en frottement continu sur ces parties métalliques : il suit logiquement une usure réelle aux points de contact des deux matières. Le frottement est d'autant plus important que les points de contact se situent à la périphérie de la balle en formation. From this design, it follows several problems related to the device as well as to the process. The first is linked to the presence of metal sides intended to impose clear edges on the pressed material. The fibrous material remains permanently in contact with these metal parts and is therefore permanently in continuous friction on these metal parts: it logically follows real wear at the points of contact of the two materials. The friction is all the more important as the contact points are located at the periphery of the ball in formation.
Le second problème est lié à la conception du dispositif. Lors de la constitution du noyau (partie centrale de la balle), les extrémités de la matière, repliées vers l'arrière sans organisation précise, peuvent occuper plusieurs spires et être emmêlées. Au déroulage, cela impose une présence humaine pour forcer le démêlage du noyau. Dans certain cas extrême, ce déroulage est presque impossible et la partie centrale doit être éliminée. The second problem is related to the design of the device. During the constitution of the core (central part of the ball), the ends of the material, folded backwards without precise organization, can occupy several turns and be tangled. On unwinding, this requires a human presence to force the untangling of the core. In some extreme cases, this unwinding is almost impossible and the central part must be eliminated.
Un troisième problème est lié avec la position des liens continus. Placés sous la nappe fibreuse, leur enroulement entre les spires doit dépasser un point critique au début de la constitution de la balle. En effet, à la première spire, ces liens, généralement des ficelles, doivent suivre la trajectoire des matières fibreuses, mais ne sont pas tenus. Cette phase A third problem is related to the position of the continuous links. Placed under the fibrous sheet, their winding between the turns must exceed a critical point at the start of the constitution of the ball. Indeed, at the first turn, these links, generally strings, must follow the path of the fibrous materials, but are not required. This phase
<Desc/Clms Page number 2><Desc / Clms Page number 2>
aléatoire conduit ces liens à ne pas s'enrouler de manière certaine entre les spires et on constate que ces ficelles poursuivre parfois leur trajectoire en dehors de la machine ou bien s'enroule autour des rouleaux métalliques. Sans ficelle entre les spires, il est alors impossible de dérouler la nappe fibreuse. random leads these links not to be wrapped in a certain way between the turns and we note that these strings sometimes continue their trajectory outside the machine or else wraps around the metal rollers. Without string between the turns, it is then impossible to unroll the fibrous web.
La présente invention permet de remédier aux problèmes évoqués ci avant. La figure 1 présente une vue du dessus et la figure 5 une vue latérale de l'avant de la machine. Les figures 2,3 et 4 présente la partie enrouleuse proprement dite et la figure 6 présente la machine dans son ensemble en vue latérale L'enrouleuse de matières fibreuses organisées est caractérisée en ce qu'elle comporte un moyen de transport plan (1), tendu entre deux cylindres (5 & 5') et animé en rotation sur lequel la matière fibreuse (2) est disposée régulièrement et perpendiculairement et au moins deux moyens fixes (3 & 3') placés au dessus et au contact de la matière fibreuse et réglables au moyen de coulisses (6 & 6'), en porte-à-faux avec les extrémités (7 & 7') libres placées en aval selon le sens d'avancement de la matière fibreuse et placé symétriquement par rapport à l'axe d'avancement de la nappe, et en ce qu'elle comporte au moins deux moyens actifs (4 & 4') dont le mouvement rotatif permet de replier chaque extrémités des fibres (2' & 2") vers le centre de la nappe, perpendiculairement à l'axe de la nappe avec comme centre de rotation l'axe de chacun des moyens fixes (3 & 3') cités ci avant. Le dispositif décrit ici permet d'organiser la nappe de matière fibreuse sur une largeur L définie par la position des moyens fixes (3 & 3'). The present invention makes it possible to remedy the problems mentioned above. Figure 1 shows a top view and Figure 5 a side view of the front of the machine. FIGS. 2, 3 and 4 show the winding part proper and FIG. 6 shows the machine as a whole in side view. The winding machine for organized fibrous materials is characterized in that it comprises a flat means of transport (1), stretched between two cylinders (5 & 5 ') and driven in rotation on which the fibrous material (2) is arranged regularly and perpendicularly and at least two fixed means (3 & 3') placed above and in contact with the fibrous material and adjustable by means of slides (6 & 6 '), cantilevered with the free ends (7 & 7') placed downstream according to the direction of advance of the fibrous material and placed symmetrically with respect to the axis advancement of the sheet, and in that it comprises at least two active means (4 & 4 ′) whose rotary movement makes it possible to fold each end of the fibers (2 ′ & 2 ″) towards the center of the sheet, perpendicular to the axis of the sheet with the axis of rotation as the center of rotation each of the fixed means (3 & 3 ') mentioned above. The device described here makes it possible to organize the sheet of fibrous material over a width L defined by the position of the fixed means (3 & 3 ').
L'enrouleuse de matière fibreuse est composé d'un ensemble de rouleau figuré sur le dessin n 2 à titre d'exemple, et d'au moins un moyen continu (8) positionné de manière à provoquer une modification de la trajectoire de la nappe de matière fibreuse (2) et lui imposer un mouvement de rotation sur elle-même susceptible de provoquer un enroulement en spirale, selon l'un des nombreux dispositifs, dit à chambre variable, existants dans ce domaine. The fibrous material winder is composed of a roller assembly shown in drawing no. 2 by way of example, and at least one continuous means (8) positioned so as to cause a modification of the path of the web. of fibrous material (2) and impose a rotational movement on it capable of causing a spiral winding, according to one of the many devices, called variable chamber, existing in this field.
Elle est caractérisée en ce que le premier rouleau (9), portant le moyen continu (8), qui vient immédiatement après le moyen de transport plan (1), reste toujours en contact tangent avec le cylindre (5') au point de contact (10) de la matière fibreuse quittant le moyen de transport plan (1). It is characterized in that the first roller (9), carrying the continuous means (8), which comes immediately after the planar means of transport (1), always remains in tangent contact with the cylinder (5 ') at the point of contact. (10) of the fibrous material leaving the planar transport means (1).

L'enrouleuse de matières fibreuses organisées se caractérise ensuite en ce qu'elle comporte un dispositif de distribution (11) d'au moins un lien continu (12) qui sépare distinctement chaque spire et que ce dispositif de distribution est placé au-dessus de la nappe de matière fibreuse de telle sorte que le moyen continu se trouve à l'intérieur de la spirale en formation et non à l'extérieur. The reel of organized fibrous materials is then characterized in that it comprises a dispensing device (11) of at least one continuous link (12) which distinctly separates each turn and that this dispensing device is placed above the sheet of fibrous material so that the continuous means is inside the spiral in formation and not outside.
Selon une première réalisation (figure 4), le dispositif de distribution (15) d'au moins un lien continu est placé au-dessus du moyen de transport plan (1) en amont de la formation de la spirale de telle sorte que le moyen continu est simplement posé sur la matière fibreuse repliée. Selon une seconde réalisation (figure 2 et 3), le dispositif de distribution d'au moins un lien continu est placé au centre du système d'enroulage et distribue au moins un lien continu entre les brins montant (13) et le brin descendant (14) de l'ensemble au contact de la matière fibreuse, c'est-à-dire sensiblement sur la partie apicale de la balle en formation. According to a first embodiment (FIG. 4), the distribution device (15) of at least one continuous link is placed above the planar transport means (1) upstream of the formation of the spiral so that the means continuous is simply placed on the folded fibrous material. According to a second embodiment (FIGS. 2 and 3), the device for distributing at least one continuous link is placed in the center of the winding system and distributes at least one continuous link between the rising strands (13) and the descending strand ( 14) of the assembly in contact with the fibrous material, that is to say substantially on the apical part of the ball in formation.
Selon une variante, les deux moyens actifs (4 et 4') sont remplacés par des jets d'air qui permettent d'orienter les extrémités des fibres (2'et 2") de manière à les replier sur ellesmêmes.According to a variant, the two active means (4 and 4 ′) are replaced by air jets which make it possible to orient the ends of the fibers (2 ′ and 2 ″) so as to fold them back on themselves.
