Abstract
Le cylindre cannelé inférieur (4) comporte, à l'extérieur de l'espace intérieur creux (11) destiné à recevoir la vapeur saturante de chauffage, des canaux longitudinaux (12) séparés et percés dans le corps périphérique du cylindre. Chaque canal (12) est relié à l'extérieur par des canaux axiaux (13) et des cavités plus larges (14) usinées sur la périphérie du cylindre, et peut être relié à un dispositif d'aspiration par l'intermédiaire de deux secteurs (15) creux et étanches en arc de cercle, s'appuyant sur la partie de la tranche du cylindre associée à la zone de retenue sur celui-ci. Les cavités (14) se présentent sous la forme de gorges allongées, disposées en quinconce et usinées sur des portions de circonférence de la périphérie du cylindre (4) de manière à s'étendre sur plusieurs ondulations de celui-ci. Un secteur additionnel de soufflage (25) permet de faciliter le décollage de la nappe de papier ondulé.The lower grooved cylinder (4) comprises, outside the hollow interior space (11) intended to receive the saturating heating vapor, longitudinal channels (12) separated and drilled in the peripheral body of the cylinder. Each channel (12) is connected to the outside by axial channels (13) and larger cavities (14) machined on the periphery of the cylinder, and can be connected to a suction device via two sectors (15) hollow and watertight in an arc of a circle, resting on the part of the edge of the cylinder associated with the retaining zone thereon. The cavities (14) are in the form of elongated grooves, staggered and machined on circumference portions of the periphery of the cylinder (4) so as to extend over several corrugations thereof. An additional blowing sector (25) makes it easier to take off the sheet of corrugated paper.
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 précisémment 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.The present invention relates to a machine for the production of corrugated cardboard coated on one. single side, commonly called "single-sided corrugator", and relates more precisely to a device for retaining the sheet of paper on the second corrugation roller, called "lower fluted cylinder", used on this kind of machine.
L'ondulation du papier est généralement obtenue dans une onduleuse simple-face par thermo-formage entre deux cylindres cannelés chauffés 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 these,
- - paper rubbing permanently on the combs, wear is fast and costs. 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 pneumatique, soit par pression soit par aspiration. De. tels-moyens n'ont cependant pas pu donner entière satisfaction jusqu'à présent car d'une part les moyens de retenue par pression ont pour inconvénient de souffler une grande partie de la colle déposée sur le papier cannelure, et d'autre part les différents moyens d'aspiration proposés jusqu'alors soit ne permettent pas une aspiration suffisante sans mise en jeu d'une énergie considérable, soit ne permettent pas de maintenir le chauffage à vapeur saturante du cylindre cannelé inférieur.Instead of using mechanical restraint, we have long thought of using pneumatic restraint, either by pressure or by suction. Such means have however not been entirely satisfactory so far because on the one hand the pressure retaining means have the disadvantage of blowing a large part of the glue deposited on the corrugated paper, and on the other hand apart from the various suction means hitherto proposed either do not allow sufficient suction without the use of considerable energy, or do not allow the saturated steam heating of the lower grooved cylinder to be maintained.
L'onduleuse simple-face de l'invention ne présente pas les inconvénients dus. aux dispositifs de retenue de la nappe de papier sur le cylindre cannelé inférieur connus jusqu'alors.-Elle est du type selon lequel le cylindre cannelé inférieur comporte un espace intérieur creux destiné à recevoir la vapeur saturante, et selon lequel la retenue du papier cannelé sur ledit cylindre cannelé inférieur s'effectue par aspiration du papier sur celui-ci, et est caractérisée en ce que ladite aspiration s'effectue par l'intermédiaire de canaux ou orifices débouchant dans des cavités plus larges usinées sur l'extérieur dudit cylindre cannelé inférieur.The single-sided corrugator of the invention does not have the disadvantages due. to the retaining devices for the sheet of paper on the lower grooved cylinder known hitherto. on said lower grooved cylinder is effected by suction of the paper thereon, and is characterized in that said suction is effected by means of channels or orifices opening into larger cavities machined on the outside of said grooved cylinder inferior.
L'invention concerne également un cylindre cannelé pour onduleuse simple-face destiné à être utilisé comme cylindre cannelé inférieur aspirant dans une onduleuse telle que définie ci-dessus.The invention also relates to a grooved cylinder for single-sided corrugator intended to be used as a lower grooved cylinder sucking in a corrugator as defined above.

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 camme 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 corrugated paper 2 is, in known manner, corrugated by passing between two
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 we do. seen in the figures, the lower grooved
A chaque extrémité du cylindre 4, et sur la tranche de celui-ci, 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, chaquecanal 12 passe alternativement dans lessecteurs 15 puis à l'air libre Le passage devant lessecteurs 15 permet de transmettre la dépression due. à la pompe à vide dans lescavités 14 qui correspondent auxcanaux 12 se trouvant dans lesdits secteurs. Le papier est par suite maintenu par aspiration contre lecylindre 4 dans toute la zone de retenue, englobée par lessecteurs 15. Ensuite, comme on le voit sur la figure 1, chaquecanal 12, lorsqu'il échappe auxsecteurs 15, est remis à l'air libre, puis entre dans les secteurs 25 ; il se produit alors un soufflage par lescavités 14, ce qui facilite le décollage de la nappe de papier ondulé ducylindre 4.
- When the
cylinder 4 rotates, eachchannel 12 passes alternately through thesectors 15 then into the open air. The passage in front of thesectors 15 makes it possible to transmit the vacuum due. to the vacuum pump in thecavities 14 which correspond to thechannels 12 located in said sectors. The paper is consequently held by suction against thecylinder 4 throughout the retaining zone, encompassed by thesectors 15. Then, as can be seen in FIG. 1, eachchannel 12, when it escapes from thesectors 15, is returned in the open air, then enters sectors 25; a blowing then takes place through thecavities 14, which facilitates the release of the corrugated paper web from thecylinder 4.
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: tuhes 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
