- the embodiment according to FIG. 11 of this US Pat. No. 3,947,206 is difficult to think of in practical terms with more than three channels 45, so that a large number of longitudinal channels 61 is necessary, which reduces the rigidity of the grooved cylinder, rigidity which is essential to ensure proper formation of the grooves.

Description
La présente invention se rapporte à une machine pour la production de carton ondulé revêtu sur une seule face, communément appelée »onduleuse simple-face«, et concerne plus précisément un dispositif de retenue de la nappe de papier sur le second rouleau d'ondulation, dit »cylindre cannelé inférieur«, utilisé sur ce genre de machine. L'invention se rapporte également à un cylindre cannelé inférieur utilisable pour une tell machine.The present invention relates to a machine for the production of corrugated cardboard coated on one side, commonly called "single-sided corrugator", and more specifically relates to a device for retaining the sheet of paper on the second corrugation roller, called "lower grooved cylinder", used on this kind of machine. The invention also relates to a lower grooved cylinder usable for a tell machine.
L'ondulation du papier est généralement obtenue dans une onduleuse simple-face par thermo-formage entre deux cylindres cannelés chauffées par leur espace intérieur creux à la vapeur saturée, et mis en application en engrènement par l'intermédiaire de deux vérins. Pour empêcher la séparation de la nappe ondulée d'avec le second rouleau d'ondulation, dit cylindre cannelé inférieur, il est nécessaire de prévoir un dispositif de retenue de la nappe sur ce dernier cylindre. Les dispositifs de retenue utilisés jusqu'alors sont d'ordre mécanique et sont constitués généralement par un ensemble de doigts de guidage, ou »peignes«, en contact avec la nappe ondulée en déplacement. De tels dispositifs de retenue présentent un certain nombre d'inconvénients:
- - le montage et le démontage des peignes est long et difficile,
- - en raison de la présence des peignes, il n'est pas possible de déposer de la colle en face de chacun de ceux-ci,
- - le papier frottant en permanence sur les peignes, l'usure est rapide et les frais de maintenance sont élevés,
- - pour décoller le papier cannelure du cylindre cannelé supérieur, les peignes doivent s'engager dans ce dernier, ce qui y implique l'usinage de gorges.
- - the assembly and disassembly of the combs is long and difficult,
- - due to the presence of the combs, it is not possible to deposit glue in front of each of them,
- - paper rubbing permanently on the combs, wear is fast and maintenance costs are high,
- - to take off the fluted paper from the upper fluted cylinder, the combs must engage in the latter, which involves the machining of grooves.
Au lieu d'utiliser des moyens de retenue mécaniques, on a depuis longtemps songé à utiliser des moyens de retenue par aspiration. Le brevet U. S. 3 947 206 en particulier décrit une onduleuse simple-face dans laquelle la retenue du papier sur le cylindre cannelé inférieur s'effectue par aspiration à travers un grand nombre de petits trous radiaux. L'alimentation de ces petits trous radiaux s'effectue par l'intermédiaire de canaux longitudinaux pouvant alimenter au maximum trois rangées de trous, une rangée étant entendue selon une génératrice du cylindre.Instead of using mechanical retaining means, consideration has long been given to using suction retaining means. U.S. Patent 3,947,206 in particular describes a single-sided corrugator in which the paper is retained on the lower grooved cylinder by suction through a large number of small radial holes. These small radial holes are supplied via longitudinal channels which can supply a maximum of three rows of holes, one row being heard along a generatrix of the cylinder.
Un tel dispositif connu implique le perçage d'un très grand nombre de petit trous dont, dans le cas schématisé sur la figure 11 de ce brevet US 3947206, certains doivent être percés totalement en biais. L'usinage d'un tel cylindre est théoriquement parfaitement réalisable, mais tellement délicat qu'il entraîne un coût de réalisation élevé. Par ailleurs, la réalisation selon la figure 11 de ce brevet US 3947206 est difficilement pensable sur plan pratique avec plus de trois canaux 45, de sorte qu'un grand nombre de canaux longitudinaux 61 est nécessaire, ce qui diminue la rigidité du cylindre cannelé, rigidité qui est indispensable pour assurer la bonne formation des cannelures.Such a known device involves the drilling of a very large number of small holes, some of which, in the case shown diagrammatically in FIG. 11 of this US Pat. No. 3,947,206, must be drilled at an angle. The machining of such a cylinder is theoretically perfectly feasible, but so delicate that it involves a high cost of production. Furthermore, the embodiment according to FIG. 11 of this US Pat. No. 3,947,206 is difficult to think of in practical terms with more than three channels 45, so that a large number of longitudinal channels 61 is necessary, which reduces the rigidity of the grooved cylinder, rigidity which is essential to ensure proper formation of the grooves.
L'onduleuse simple-face de l'invention ne présente pas les inconvénients dus aux dispositifs décrits ci-dessus. Elle est du type comportant, pour la formation de la cannelure du papier, un cylindre cannelé supérieur et un cylindre cannelé inférieur mis en application en engrènement, au moins le cylindre cannelé inférieur possédant un espace intérieur creux destiné à recevoir de la vapeur saturante de chauffage, ladite onduleuse étant du type selon lequel la retenue du papier cannelé sur le cylindre cannelé inférieur s'effectue par aspiration du papier sur ledit cylindre par l'intermédiaire de canaux ou orifices, et est caractérisée en ce que ces canaux ou orifices débouchent dans des cavités plus larges se présentant sous la forme de gorges allongées réalisées sur des portions de circonférence, usinées transversalement sur la périphérie dudit cylindre cannelé inférieur, s'étendant sur plusieurs ondulations de celui-ci, et disposées en quinconce.The single-sided corrugator of the invention does not have the drawbacks due to the devices described above. It is of the type comprising, for the formation of the groove of the paper, an upper grooved cylinder and a lower grooved cylinder applied in meshing, at least the lower grooved cylinder having a hollow interior space intended to receive saturating steam for heating. , said corrugator being of the type according to which the retention of the corrugated paper on the lower corrugated cylinder is effected by suction of the paper on the said cylinder via channels or orifices, and is characterized in that these channels or orifices open into wider cavities in the form of elongated grooves formed on circumference portions, machined transversely on the periphery of said lower grooved cylinder, extending over several corrugations thereof, and arranged in staggered rows.
L'invention concerne également un cylindre cannelé pour onduleuse simple-face, ledit cylindre étant du type possédant un espace intérieur creux destiné à recevoir de la vapeur saturante de chauffage, et comportant, à l'extérieur dudit espace intérieur creux, des canaux longitudinaux séparés et percés dans la partie périphérique du corps dudit cylindre, ainsi que des canaux radiaux ou orifices reliant lesdits canaux longitudinaux à l'extérieur, et il est caractérisé en ce que lesdite canaux radiaux ou orifices y débouchent dans des cavités plus larges se présentant sous la forme de gorges allongées réalisées sur des portions de circonférence, usinées transversalement sur la périphérie dudit cylindre, s'étendant sur plusieurs ondulations de celui-ci, et disposées en quinconce.The invention also relates to a grooved cylinder for a single-sided corrugator, said cylinder being of the type having a hollow interior space intended to receive saturating heating vapor, and comprising, outside said hollow interior space, separate longitudinal channels. and drilled in the peripheral part of the body of said cylinder, as well as radial channels or orifices connecting said longitudinal channels to the outside, and it is characterized in that said radial channels or orifices open therein into larger cavities which are presented under the form of elongated grooves made on circumference portions, machined transversely on the periphery of said cylinder, extending over several corrugations thereof, and arranged in staggered rows.

En se reportant aux figures 1 à 5, le papier cannelure 2 est, de manière connue, ondulé par passage entre deux cylindres cannelés 3 et 4 placés l'un au dessus de l'autre comme représenté sur les dessins, puis collé sur un papier couverture 1 entre le cylindre cannelé inférieur 4 et un cylindre lisse 5, pour sortir finalement de la machine sous forme d'une bande de carton ondulé simple-face 9. Les cylindres 3 et 4 sont chauffés par de la vapeur à température de 200°C environ et sous pression de 16 bars environ admise, par un dispositif classique non représenté, à l'intérieur des cylindres qui sont donc creux en conséquence, ce qui permet au papier d'atteindre la température optimale pour le thermo-formage de la cannelure. Le papier cannelure reçoit la colle par un cylindre 6 qui trempe dans un bac de colle 8. L'épaisseur de colle déposée sur le papier est réglée par l'intervalle existant entre le cylindre 6 et un cylindre auxiliaire 7.Referring to Figures 1 to 5, the
Comme on le voit sur les figures, le cylindre cannelé inférieur 4 est usiné, de manière classique, sous forme d'une virole 10 permettant l'admission de la vapeur dans son espace intérieur 11. Par ailleurs, un grand nombre de canaux longitudinaux 12 sont percés dans le corps de la virole 10 de manière à être régulièrement répartis sur toute la laize du cylindre. Des trous axiaux 13 d'un plus petit diamètre sont en outre percés tous les 8 cm environ le long de chaque canal 12 et, conformément à l'invention, mettent en communication chacun de ceux-ci avec des cavités plus larges 14 usinées sur l'extérieur du cylindre cannelé 4. Les cavités 14 se présentent sous la forme de gorges allongées usinées sur des portions de circonférence de la périphérie du cylindre 4, disposées en quinconce sur ladite périphérie comme on le voit sur la figure 2, et s'étendant sur plusieurs ondulations dudit cylindre. Comme on le voit en particulier sur la figure 5, les cavités 14 ont par ailleurs une section en forme d'arc de cercle et, s'étendant sur plusieurs ondulations du cylindre, ont une profondeur P supérieure à celle h du profil de cannelure.As can be seen in the figures, the lower grooved
A chaque extrémité du cylindre 4, et sur la tranche de celuici, est installé un secteur 15 fixe, étanche, creux et en arc de cercle, qui s'appuie sur la partie de la tranche du cylindre 4 qui correspond à la zone de retenue du papier sur le cylindre 4 pendant son trajet entre les cylindres 3 et 5. Chaque secteur creux 15 est relié à une pompe à vide non représentée et fonctionnant en permanence. Par ailleurs, deux secteurs creux et étanches supplémentaires 25 sont placés immédiatement à la suite des secteurs 15, un sur chaque tranche du cylindre 4. Les secteurs 25 sont de largeur suffisante pour pouvoir englober au moins un des canaux 12 et sont alimentés par une source d'air comprimé non représentée.At each end of the
Le fonctionnement du dispositif de retenue du papier cannelure sur le cylindre 4 est le suivant: Lorsque le cylindre 4 tourne, chaque canal 12 passe alternativement dans les secteurs 15 puis à l'air libre. Le passage devant les secteurs 15 permet de transmettre la dépression due à la pompe à vide dans les cavités 14 qui correspondent aux canaux 12 se trouvant dans lesdits secteurs. Le papier est par suite maintenu par aspiration contre le cylindre 4 dans toute la zone de retenue, englobée par les secteurs 15. Ensuite, comme on le voit sur la figure 1, chaque canal 12, lorsqu'il échappe aux secteurs 15, est remis à l'air libre, puis entre dans les secteurs 25; il se produit alors un soufflage par les cavités 14, ce qui facilite le décollage de la nappe de papier ondulé du cylindre 4.The operation of the groove paper retainer on the
Sur la figure 6, on a schématisé une variante perfectionnée du dispositif précédent permettant de travailler avec des laizes de papier cannelure de différentes tailles. Selon cette variante, deux plateaux annulaires 16, sur lesquels sont soudés des tubes 17 coulissants dans les extrémités de chaque canal 12, sont rendus solidaires du cylindre cannelé 4 et tournent donc avec lui. La valeur de l'enfoncement des tubes 17 dans les canaux 12 est règlée par deux vis 23 se vissant longitudinalement dans le corps du cylindre cannelé 4.In FIG. 6, an improved variant of the previous device has been shown diagrammatically, making it possible to work with widths of corrugated paper of different sizes. According to this variant, two
Dans les tubes 17 et dans la partie supérieure de ceux-ci sont percés plusieurs trous (18, 19, 20) espacés de manière à ce que leurs bords situés vers la tranche du cylindre 4 soient distants de l'intervalle séparant deux trous 13 et à ce que leur diamètre soit égal pour le premier trou 18 au diamètre d d'un trou 13, puis à 2d pour le second trou 19 et à 3d pour le troisième et dernier trou 20.In the
En position de coulissement 0 représentée sur le dessin, chacun des trois trous 18, 19, 20 est en face d'un des orifices 13 de sorte que le vide est transmis vers les cavités 14 correspondantes, ce qui permet le travail à pleine laize L comme représenté sur le dessin.In the sliding position 0 shown in the drawing, each of the three
Si l'on veut travailler en laize A plus étroite, on provoque, par rotation de chaque vis 23 vers l'extérieur, la sortie de chaque cylindre 17 d'une quantité d, de sorte que chaque premier orifice tel que 13a se trouve bouché alors que tous les orifices suivants tels que 13b et 13c sont toujours reliés à la pompe à vide.If we want to work in narrower width A, we cause, by rotation of each
De même, pour une laize B encore plus étroite, on provoque un coulissement 2d vers l'extérieur. Le premier trou 18 n'est toujours plus en correspondance avec son orifice 13a et le second trou 19 n'est également plus en correspondance avec son orifice 13b, de sorte que l'on aspire bien sur la laize B et non pas à l'extérieur.Similarly, for an even narrower width B, a 2d sliding towards the outside is caused. The
Pour une laize C encore plus petite, on provoque de même un déplacement 3d de manière à boucher le troisième orifice 13c. On pourrait continuer ainsi de suite avec des tubes 17 plus longs.For an even smaller width C, a 3d displacement is likewise caused so as to block the
Grâce à ce dispositif additionnel, on n'aspire ainsi que dans la zone réellement couverte par le papier cannelure même pour des laizes inférieures à la pleine laize.Thanks to this additional device, it only sucks in the area actually covered by the corrugated paper even for widths less than the full width.
La figure 7 schématise une variante des deux dispositifs précédents, relative au cas où, selon la vitesse et la qualité du papier, on est amené à déplacer le point A correspondant au début du plaquage par aspiration du papier sur le cylindre 4. Une denture 21 est alors taillée dans chacun des secteurs 15, et cette denture s'engrène avec un pignon 22 monté sur l'arbre d'un moteur non représenté. En faisant tourner le moteur dans un sens ou dans l'autre, le pignon 22 fait tourner de manière correspondante le secteur 15 par l'intermédiaire de la denture 21. Par l'intermédiaire d'une génératrice tachymétrique, montée sur le moteur d'entraînement de l'ensemble de l'onduleuse simple-face et reliée au moteur d'entraînement des deux pignons 22, on peut alors aisément asservir la position des deux secteurs 15 en fonction de la vitesse de l'onduleuse.Figure 7 shows schematically a variant of the two previous devices, relating to the case where, depending on the speed and quality of the paper, it is necessary to move the point A corresponding to the start of the plating by suction of the paper on the
