Description

L'invention concerne une machine à papier à poutre mobile, plus particulièrement pour le changement de la toile sur la table de fabrication de la machine à papier.The invention relates to a mobile beam paper machine, more particularly for changing the fabric on the manufacturing table of the paper machine.

Dans une machine à papier de type classique, la pâte à papier est déposée en nappe à une extrémité de la table de fabrication, et à l'autre extrémité, on prélève la feuille continue qui est dirigée vers la presse. La table de fabrication a une longueur de plus de 15 m. Elle est recouverte d'une toile, qui est un support sans fin passant sur et sous la table, et assurant, pendant le transport de la pâte sur la table, l'élimination d'une partie de l'eau contenue dans la pâte, de sorte qu'entre une extrémité et l'autre de la table, la concentration en fibre passe de 1 % environ à 27 % environ.In a paper machine of conventional type, the paper pulp is deposited in a sheet at one end of the manufacturing table, and at the other end, the continuous sheet is taken which is directed towards the press. The manufacturing table has a length of more than 15 m. It is covered with a canvas, which is an endless support passing over and under the table, and ensuring, during the transport of the dough on the table, the elimination of part of the water contained in the dough, so that between one end and the other of the table, the fiber concentration goes from about 1% to about 27%.

Cette toile, qui travaille en continu, est soumise à une certaine usure et à un phénomène de colmatage, ce qui rend nécessaire son remplacement après une durée de vie de deux à trois mois en moyenne. Le remplacement de la toile est une opération delicate et longue.This canvas, which works continuously, is subject to a certain wear and a clogging phenomenon, which makes it necessary to replace it after a service life of two to three months on average. Replacing the canvas is a delicate and time-consuming operation.

Dans les machines à table sortante, on déplace la table transversalement hors de la machine à papier, puis on change la toile, et on remet en place la table. Une table peut peser plus de 40 T : il faut donc une infrastructure comportant des rails de support, les galets de roulement sont soumis à des contraintes mécaniques importantes, et l'opération dure environ 8 heures.In outgoing table machines, the table is moved transversely out of the paper machine, then the canvas is changed, and the table is replaced. A table can weigh more than 40 T: an infrastructure comprising support rails is therefore required, the rollers are subjected to significant mechanical stresses, and the operation lasts approximately 8 hours.

Dans d'autres machines dites en porte-à-faux, on enlève les supports de table sur l'un des côtés longitudinaux, le côté du conducteur de la machine, et toute la table est supportée par l'autre côté, le côté comportant les organes de transmission. On coupe la toile usée et on l'enlève. On met la nouvelle toile en place sur un gabarit parallèle à la machine, et on la glisse sur la table, puis on la tend au moyen des rouleaux tendeurs disposés sous la table. Enfin, on remet en place les supports.In other so-called cantilever machines, the table supports are removed on one of the longitudinal sides, the driver's side of the machine, and the entire table is supported on the other side, the side comprising the transmission members. We cut the worn canvas and remove it. We put the new canvas in place on a template parallel to the machine, and we slide it on the table, then we stretch it by means of the tension rollers placed under the table. Finally, the supports are replaced.

Pour réduire les efforts mécaniques résultant du porte-­à-faux, il est connu de rapporter de l'extérieur une poutre qui pèse de 1 à 2 T, de la fixer à la table en passant dans l'anneau constitué par la nouvelle toile, et de la verrouiller, l'extrémité de la poutre étant posée sur un support, au sol. La table étant alors tenue par cette poutre, on peut enlever les supports de table du côté du conducteur et procéder au remplacement de la toile. Cette méthode de la poutre rapportée présente certains inconvénients. Tout d'abord, il faut stocker la poutre et son support, ce qui mobilise de la place. Ensuite, il faut manutentionner la poutre, ce qui nécessite un pont roulant, par exemple. Enfin, au cours de ces manoeuvres difficiles en raison de la masse de la poutre, les risques de déchirure de la nouvelle toile sont assez élevés. Par ailleurs, pour que la machine soit stable lors de sa mise en porte-à-­faux, il est nécessaire de prévoir une structure d'encastrement du côté opposé au conducteur.To reduce the mechanical forces resulting from the overhang, it is known to bring in from the outside a beam which weighs from 1 to 2 tonnes, to fix it to the table passing through the ring formed by the new canvas, and to lock it, the end of the beam being placed on a support, on the ground. The table then being held by this beam, we can remove the table supports on the driver's side and replace the canvas. This method of the added beam has certain drawbacks. First of all, the beam and its support must be stored, which takes up space. Then you have to handle the beam, which requires an overhead crane, for example. Finally, during these difficult maneuvers due to the mass of the beam, the risks of tearing of the new fabric are quite high. Furthermore, in order for the machine to be stable when it is cantilevered, it is necessary to provide a mounting structure on the side opposite the conductor.

Il est par ailleurs connu par le document US-A-2 90̸3 0̸60̸, de prévoir une machine à papier en porte-à-faux munie de poutres télescopiques constituées de cylindres fixes dans lesquels peuvent coulisser des pistons. Les pistons sont déplaçables par application d'air comprimé au moyen de canalisations coaxiales aux poutres. Une telle réalisation, si elle est satisfaisante sur le plan conceptuel, est mécaniquement très décevante : avec les longueurs de poutre de ce type de machine, les problèmes d'étanchéité sont très difficiles à résoudre, et la commande des déplacements du piston par air comprimé pratiquement impossible à réaliser.It is also known from document US-A-2 90̸3 0̸60̸, to provide a cantilevered paper machine provided with telescopic beams made up of fixed cylinders in which pistons can slide. The pistons can be moved by applying compressed air by means of pipes coaxial with the beams. Such an achievement, if it is conceptually satisfactory, is mechanically very disappointing: with the beam lengths of this type of machine, the sealing problems are very difficult to solve, and the control of the movements of the piston by compressed air practically impossible to achieve.

L'un des buts de l'invention est d'éviter les inconvénients précédents en permettant un remplacement aisé et rapide de la toile sur les machines à papier dites en porte-à-faux.One of the aims of the invention is to avoid the above drawbacks by allowing easy and rapid replacement of the fabric on the so-called cantilevered paper machines.

La présente invention a pour objet une machine à papier, du type table de fabrication en porte-à-faux, comportant des longerons transversaux soutenus par des supports amovibles, du type dans lequel chaque longeron comporte une poutre mobile déplaçable longitudinalement par rapport au longeron, et dont l'extrémité libre, après avoir traversé l'anneau constitué par la nouvelle toile à mettre en place sur la table , est supportée par un vérin hydraulique de façon à autoriser l'enlèvement des supports amovibles et la mise en place de la nouvelle toile, caractérisée en ce que la poutre mobile est supportée par un chariot suspendu à un axe de pivotement.The subject of the present invention is a paper machine, of the cantilever manufacturing table type, comprising transverse beams supported by removable supports, of the type in which each beam has a movable beam movable longitudinally relative to the beam, and the free end of which, after having passed through the ring formed by the new fabric to be placed on the table, is supported by a hydraulic jack so as to allow the removal of the removable supports and the installation of the new canvas, characterized in that the mobile beam is supported by a carriage suspended from a pivot axis.

Selon d'autres caractéristiques de l'invention :
- le chariot constitue un berceau de supports à galets dont certains sont entraînés au moyen d'un volant de manoeuvre ,
- le chariot est supporté par une console de renfort du longeron ,
- la poutre présente une nervure transversale coopérant avec les doigts d'un verrou de sécurité pour le blocage de la poutre en position de service,
- sous la console est disposée une cale pour la reprise des efforts de support de la table.According to other characteristics of the invention:
- the carriage constitutes a cradle of roller supports, some of which are driven by means of an operating wheel,
- the carriage is supported by a reinforcement console of the beam,
the beam has a transverse rib cooperating with the fingers of a safety lock for blocking the beam in the service position,
- under the console is a shim for the recovery of the table support forces.

A titre d'exemple, on a représenté au dessin annexé :

  • Figure 1 : une vue en coupe longitudinale partielle d'une table de fabrication d'une machine à papier du type en porte-à-faux, selon l'invention ;
  • Figure 2 : une vue de gauche de la table de la figure 1 pendant l'opération de changement de toile,
  • Figure 3 : une vue en coupe selon la ligne AA de la figure 2 ;
  • Figure 4 : une vue en coupe selon la ligne BB de la figure 2.
By way of example, the accompanying drawing shows:
  • Figure 1: a partial longitudinal sectional view of a manufacturing table of a paper machine of the cantilever type, according to the invention;
  • Figure 2: a left view of the table in Figure 1 during the canvas change operation,
  • Figure 3: a sectional view along line AA of Figure 2;
  • Figure 4: a sectional view along line BB of Figure 2.

En se reportant à la figure 1, on voit une table 1 de fabrication pour machine à papier de type classique, habillée par une toile 2, plastique par exemple, sans fin, qui est entraînée dans le sens de la flèche. La pâte à papier provenant de la caisse de tête 3 est déposée sur la toile, et après passage sur la table, une feuille est prélevée en 4 et acheminée vers la presse. La toile est tendue, sous la table, par des tendeurs tels que 5. Au niveau de ses longerons transversaux 6, 7, la table est soutenue par des supports 8, 9, amovibles.Referring to Figure 1, we see a manufacturing table 1 for a conventional type paper machine, covered by a canvas 2, plastic for example, endless, which is driven in the direction of the arrow. The paper pulp from the head box 3 is placed on the canvas, and after passing over the table, a sheet is taken at 4 and conveyed to the press. The canvas is stretched under the table by tensioners such as 5. At its transverse beams 6, 7, the table is supported by removable supports 8, 9.

Sur la figure 2, on voit mieux la disposition des longerons transversaux et des supports amovibles. Dans le longeron 6 est logée une poutre mobile 10̸, profilée en I, en acier mécano-soudé par exemple. Le longeron 6 se prolonge vers la droite un peu au-delà du support amovible 8 pour bien assurer le guidage de la poutre mobile 10̸. L'extrémité de la poutre intérieure au longeron est munie d'un galet supérieur 11 et d'un galet inférieur 12. Le galet supérieur 11 est de préférence bombé, réglable en hauteur et monté sur bagues en bronze. Il reprend les efforts dus au couple provoqué par le basculement de la poutre quand son centre de gravite dépasse les points d'appui des galets du chariot 13.In Figure 2, we can better see the arrangement of the transverse beams and removable supports. In the longitudinal member 6 is housed a movable beam 10̸, I-shaped, in mechanically welded steel for example. The spar 6 extends to the right a little beyond the removable support 8 to ensure the guiding of the mobile beam 10̸. The end of the inner beam to the spar is provided with an upper roller 11 and a lower roller 12. The upper roller 11 is preferably curved, adjustable in height and mounted on bronze rings. It takes up the forces due to the torque caused by the tilting of the beam when its center of gravity exceeds the support points of the rollers of the carriage 13.

Le galet 12 est de préférence monté sur un roulement à rotule sur rouleaux. Il reprend les efforts dus au couple de bras de levier (d). L'extrémité extérieure de la poutre 10̸ est portée par un chariot 13 suspendu à une console 14 qui renforce le longeron 6. Au-delà de l'extrémité du longeron 6 est prévue une cale 15, fixée sous la console 14, pour assurer la transmission des efforts de support de la table lors du changement de la toile.The roller 12 is preferably mounted on a spherical roller bearing. It takes up the forces due to the lever arm torque (d). The outer end of the beam 10̸ is carried by a carriage 13 suspended from a console 14 which reinforces the spar 6. Beyond the end of the spar 6 is provided a wedge 15, fixed under the console 14, to ensure the transmission of table support forces when changing the fabric.

Lorsque la poutre mobile 10̸ est en position de service (figure 2) son extrémité libre repose sur un vérin hydraulique 16, par exemple, qui assure le support de la table. On peut alors enlever le support amovible 8, la stabilité de la table étant assurée par la poutre mobile 10̸, entre le vérin 16, le galet inférieur 12 et la cale 15.When the movable beam 10̸ is in the service position (Figure 2) its free end rests on a hydraulic cylinder 16, for example, which provides support for the table. The removable support 8 can then be removed, the stability of the table being ensured by the mobile beam 10̸, between the jack 16, the lower roller 12 and the wedge 15.

Sur la figure 3, on voit que le chariot 13 est suspendu à un axe d'articulation 17. Le chariot porte quatre galets tels que 18, 19, qui supportent la poutre 10̸. Les galets 18 sont susceptibles d'être entraînés en rotation dans le même sens au moyen du volant de manoeuvre 20̸, pour déplacer la poutre dans le longeron 6. La disposition des quatre galets sur le chariot qui est suspendu par un seul axe permet une meilleure répartition des efforts entre les quatre galets qui se comportent comme un berceau de support pour la poutre.In Figure 3, we see that the carriage 13 is suspended from a hinge pin 17. The carriage carries four rollers such as 18, 19, which support the beam 10̸. The rollers 18 can be rotated in the same direction by means of the handwheel 20̸, to move the beam in the beam 6. The arrangement of the four rollers on the carriage which is suspended by a single axis allows better distribution of forces between the four rollers which behave like a support cradle for the beam.

Sur la figure 4, on voit que la poutre 10̸ présente une nervure transversale 21 dans le plan de la coupe BB. Cette nervure est bloquée entre deux doigts 22 d'un verrou de sécurité assurant l'immobilisation de la poutre en position de service.In Figure 4, we see that the beam 10̸ has a transverse rib 21 in the plane of the section BB. This rib is locked between two fingers 22 of a safety lock ensuring the immobilization of the beam in the service position.

Dans la machine à papier selon l'invention, le changement de toile se déroule de la façon suivante : on présente la nouvelle toile 23, parallèlement à la table 1, sur un gabarit constitué de bâtons de toile 24 et de supports de bâtons de toile 25 (figure 2). Au moyen du volant de manoeuvre 20̸, on fait sortir la poutre 10̸ du longeron 6 de façon qu'elle traverse l'anneau constitué par la nouvelle toile. On bloque la poutre en position au moyen de verrou de sécurité.In the paper machine according to the invention, the change of fabric takes place in the following way: the new fabric 23 is presented, parallel to the table 1, on a template made of canvas sticks 24 and canvas stick supports 25 (Figure 2). By means of the handwheel 20̸, the beam 10̸ is taken out of the spar 6 so that it crosses the ring formed by the new fabric. The beam is locked in position by means of a safety lock.

On met en place le vérin hydraulique 16 sous l'extrémité libre de la poutre 0̸, et, en chargeant le vérin 16, on reprend l'effort de support de la table 1 sur ce vérin. On enlève le support amovible 8. On coupe la toile usée et on l'enlève. On met la nouvelle toile 23 en place par déplacement transversal et on la tend. On remet en place le support amovible 8, on décharge le vérin 16, on enlève le verrou de sécurité, et on remet la poutre 10̸ dans le longeron 6 au moyen du volant de manoeuvre 20̸.The hydraulic cylinder 16 is put in place under the free end of the beam 0̸, and, by loading the cylinder 16, the support force of the table 1 is taken up on this cylinder. The removable support 8 is removed. The used canvas is cut and removed. The new fabric 23 is put in place by transverse displacement and it is stretched. The removable support 8 is replaced, the jack 16 is unloaded, the safety lock is removed, and the beam 10̸ is put back in the beam 6 by means of the handwheel 20 volant.

La disposition de la poutre mobile selon l'invention présente plusieurs avantages. Tout d'abord, il s'agit d'une simple poutre mécanosoudée en acier, profilée en I. Ensuite, elle est entièrement logée dans le longeron, ce qu fait qu'elle est toujours disponible et sur place, sans avoir besoin d'être stockée dans un endroit spécifique. Etant dans le longeron, elle est toujours à l'abri, notamment de l'eau, puisque protégée, à l'avant, par la console 14. Sa mise en position s'effectue par simple manoeuvre d'un volant, sans recours à d'autres moyens de manutention. Le seul accessoire extérieur à prévoir est un vérin hydraulique de type classique. Enfin, un changement de toile ne dure qu'une heure environ, ce qui réduit considérablement la durée d'immobilisation de la machine.The arrangement of the mobile beam according to the invention has several advantages. First, it is a simple mechanically welded steel beam, I-shaped. Then, it is fully housed in the beam, which means that it is always available and on site, without the need for be stored in a specific place. Being in the spar, it is always sheltered, in particular from water, since protected, at the front, by the console 14. Its positioning is carried out by simple operation of a steering wheel, without recourse to other means of handling. The only external accessory to provide is a conventional type hydraulic cylinder. Finally, a change of fabric lasts only about an hour, which considerably reduces the machine's downtime.

L'invention a été décrite seulement dans la zone de la table de fabrication de la feuille de papier. Il va de soi qu'elle s'applique à toute partie de la chaîne de fabrication du papier qui comporte une toile à changer.The invention has been described only in the area of the paper sheet manufacturing table. It goes without saying that it applies to any part of the paper manufacturing chain which includes a canvas to be changed.
