Abstract

The infeed station (10) comprises an eccentric roller (13) mounted between two rotary plates around which a web material (5) travels in such a manner that its speed of advance is converted from a constant inlet speed to an outlet speed which varies under predetermined conditions during an operating cycle of the station. The station also comprises an infeed roller (15) which guides the web of material from the eccentric roller to the platen press. The infeed roller is driven by a DC motor in such a manner that its peripheral speed varies in similar manner to the outlet speed of the web material while permanently remaining at a higher value.

Description

La présente invention est relative à une station d'introduction d'une matière en bande, par exemple du carton, à une station la travaillant séquentiel- lement, telle qu'une presse à platine.The present invention relates to a station for introducing a strip material, for example cardboard, to a station working it sequentially, such as a platen press.

La presse à platine étant une machine exigeant un arrêt momentané du défilement de la matière en bande lors du travail de découpage, il se produit, en raison de l'alimentation continue, une accumulation de matière en bande avant cette platine de découpage. Les constructeurs de machine ont donc conçu une station d'introduction permettant de maîtriser cycliquement la formation d'une boucle de matière en bande de façon à réduire au maximum l'effet de claquage de cette bande à l'instant où la boucle touche l'organe de réglage de boucle, et ce en utilisant un dispositif conduisant la matière en bande autour de la circonférence d'un rouleau excentré monté entre deux plateaux rotatifs comme décrit, par exemple, dans le brevet suisse CH 602 462.The platen press being a machine requiring a temporary stop of the running of the strip material during the cutting work, it occurs, due to the continuous feeding, an accumulation of strip material before this cutting platen. The machine builders have therefore designed an introduction station making it possible to cyclically control the formation of a loop of strip material so as to minimize the breakdown effect of this strip at the instant when the loop touches the loop adjusting member, and this by using a device conducting the strip material around the circumference of an eccentric roller mounted between two rotary plates as described, for example, in Swiss patent CH 602 462.

Grâce à ce rouleau excentrique du dispositif de contrôle de boucle, la vitesse constante VO de défilement de la bande à l'entrée de la station, est transformée, à chaque cycle de travail de la machine, en une vitesse intermittente VIT tout en gardant une tension constante dans la bande. L'évolution de la vitesse VIT au cours d'un cycle de travail de la machine, ce cycle pouvant être divisé en unité de temps mais étant plus généralement divisé en unité de position angulaire du moteur principal de la station, suit une courbe prédéterminée et optimisée par rapport aux caractéristiques dynamiques de la matière en bande.Thanks to this eccentric roller of the loop control device, the constant speed VO of movement of the tape at the entrance to the station, is transformed, at each working cycle of the machine, into an intermittent speed VIT while keeping a constant tension in the belt. The evolution of the speed VIT during a working cycle of the machine, this cycle being able to be divided into unit of time but being more generally divided into unit of angular position of the main engine of the station, follows a predetermined curve and optimized with respect to the dynamic characteristics of the strip material.

La matière en bande sortant avec une vitesse modulée du rouleau excentré est conduite par un dernier rouleau, dit "rouleau d'introduction", vers la platine. Afin d'éviter un effondrement de la tension au sein de la matière en bande au niveau du rouleau d'introduction lors du maximum de vitesse de défilement VIT, la vitesse périphérique de ce rouleau d'introduction VRO est fixée à une valeur assez haute, supérieure à ce maximum. En d'autres termes, le rouleau d'introduction est entraîné en permanence par le moteur principal et un train d'engrenage de la station à une vitesse de rotation constante faisant que sa vitesse périphérique reste toujours supérieure à la vitesse de défilement momentanée de la matière en bande, ce qui se traduit par un patinage permanent de la bande sur le rouleau d'introduction. Le travail des forces de friction présentes sur la surface de contact ban- de/rouleau se dissipe en chaleur, ce qui nécessite un important dispositif de refroidissement de ce rouleau d'introduction.The strip material exiting with a modulated speed from the eccentric roller is led by a last roller, called "introduction roller", towards the plate. In order to avoid a collapse of the tension within the strip material at the level of the introduction roller during the maximum running speed VIT, the peripheral speed of this introduction roller VRO is fixed at a fairly high value, greater than this maximum. In other words, the feed roller is permanently driven by the main motor and a gear train of the station at a constant speed of rotation so that its peripheral speed always remains greater than the momentary speed of travel of the strip material, which results in permanent slippage of the strip on the feed roller. The work of the friction forces present on the bank / roller contact surface dissipates into heat, which requires a significant cooling device for this introduction roller.

Fonctionnant à satisfaction pour des cartons normaux, ce dispositif trouve toutefois rapidement sa limite dès lors que l'on envisage d'augmenter la cadence de production, donc les vitesses de défilement; et surtout dans le cas de carton revêtu d'une couche délicate côté verso, par exemple une couche de polyéthylène. Alors, l'échauffement et les forces de friction présents entre le rouleau d'introduction et le carton chauffent et arrachent partiellement cette couche délicate, et on retrouve de la matière plastique à l'état pâteux dans les refou- leurs femelles de la platine. De plus, il apparaît des traces d'accélération inadmissibles sur le carton en fonction de la position des courroies d'introduction.Operating satisfactorily for normal boxes, this device quickly finds its limit as soon as it is envisaged to increase the production rate, therefore the running speeds; and especially in the case of cardboard coated with a delicate layer on the back side, for example a layer of polyethylene. Then, the heating and the frictional forces present between the introduction roller and the cardboard heat and partially tear off this delicate layer, and plastic material is found in a pasty state in the female refusers of the plate. In addition, inadmissible acceleration marks appear on the cardboard depending on the position of the insertion belts.

Il n'est guère possible d'augmenter indéfiniment la puissance du dispositif de refroidissement à eau du cylindre d'introduction, car on arrive à générer de l'eau de condensation externe qui crée un phénomène de dérapage entre la bande et le rouleau. De plus, de telles machines peuvent être utilisées dans des environnements déjà surchauffés, notamment en été.It is hardly possible to indefinitely increase the power of the water cooling device of the introducer cylinder, since we manage to generate external condensation water which creates a slippage phenomenon between the strip and the roller. In addition, such machines can be used in already overheated environments, especially in summer.

Par ailleurs, l'accélération étant proportionnelle au carré de la vitesse, on se rend rapidement compte qu'une augmentation de 40% de la vitesse de défilement de la matière en bande implique le doublement de force d'accélération en présence se répercutant normalement sur l'ensemble de la chaîne cinématique d'entraînement général de la machine, ce qui conduit rapidement à un surdi- mensionnement irréaliste de certains organes.Furthermore, the acceleration being proportional to the square of the speed, we quickly realize that an increase of 40% in the speed of movement of the strip material implies the doubling of the acceleration force in the presence which is normally reflected in the entire kinematic chain for the general drive of the machine, which quickly leads to an unrealistic oversizing of certain components.

Le but de la présente invention est d'obvier les problèmes précités en proposant une station d'introduction autorisant une cadence de fonctionnement plus élevée, même pour des cartons délicats, tout en préservant l'intégrité du matériau de la bande ou d'une couche périphérique, et en respectant les limites mécaniques des organes d'entraînement de la machine.The object of the present invention is to obviate the aforementioned problems by proposing an introduction station allowing a higher operating rate, even for delicate cartons, while preserving the integrity of the material of the strip or of a layer. peripheral, and respecting the mechanical limits of the machine's drive members.

Ces buts sont réalisés grâce à une station d'introduction comprenant un rouleau excentré monté entre deux plateaux rotatifs autour duquel passe la matière en bande de telle sorte que sa vitesse de défilement soit transformée d'une vitesse d'entrée constante VO en une vitesse de sortie VIT évoluant selon un régime prédéterminé au cours d'un cycle de travail de la station, ainsi qu'un rouleau d'introduction guidant la bande de matière du rouleau excentré vers la platine, du fait que le rouleau d'introduction est entraîné par un dispositif indépendant de telle sorte que sa vitesse périphérique VR suive un régime similaire à la vitesse de sortie VIT de la matière en bande tout en restant en permanence à une valeur supérieure.These goals are achieved thanks to an introduction station comprising an eccentric roller mounted between two rotary plates around which the strip material passes so that its speed of movement is transformed from a constant input speed VO into a speed of VIT output evolving according to a predetermined speed during a work cycle of the station, as well as an introduction roller guiding the strip of material from the eccentric roller towards the plate, due to the fact that the introduction roller is driven by an independent device such that its peripheral speed VR follows a speed similar to the speed of exit VIT of the strip material while remaining permanently at a higher value.

Grâce à ce dispositif d'entraînement indépendant du moteur principal de la station, on applique au rouleau d'introduction une vitesse périphérique VR croissante puis décroissante simultanément avec la vitesse intermittente VIT de la matière en bande de telle sorte que l'écart entre ces deux vitesses, maintenu toujours positif, soit minimisé au mieux. Ce pilotage particulier du rouleau d'introduction se traduit par une diminution sensible de la chaleur dégagée par frottement préservant seulement alors une couche fragile de la matière en bande, ou autorisant, à dispositif de refroidissement identique, une cadence accrue de passage de bande de matière.Thanks to this drive device independent of the main motor of the station, a peripheral speed VR increases then decreases simultaneously with the intermittent speed VIT of the strip material is applied to the feed roller so that the difference between these two speeds, always kept positive, or minimized at best. This particular piloting of the intro roll duction results in a significant reduction in the heat given off by friction preserving only then a fragile layer of the strip material, or allowing, with identical cooling device, an increased rate of passage of strip of material.

Selon un mode de réalisation préféré, le dispositif d'entraînement indépendant du rouleau d'introduction est constitué d'un moteur électrique à courant continu complété d'un engrenage réducteur limité à deux paires de roues dentées.According to a preferred embodiment, the independent drive device of the introduction roller consists of a direct current electric motor supplemented with a reduction gear limited to two pairs of toothed wheels.

Le moteur électrique est relié à l'arbre du rouleau d'introduction par deux engrenages, un premier ayant un rapport de l'ordre de 20:36, le second un rapport de l'ordre de 15:38, le moment d'inertie total du cylindre, de l'engrenage et du moteur tel que rapporté au niveau de l'axe de sortie du moteur n'excédant pas 0,04 kgm2.The electric motor is connected to the shaft of the feed roller by two gears, the first having a ratio of about 20:36, the second a ratio of about 15:38, the moment of inertia total of the cylinder, gear and motor as reported at the level of the motor output axis not exceeding 0.04 kgm2.

L'invention sera mieux comprise à l'étude d'un mode de réalisation pris à titre d'exemple nullement limitatif et décrit par les figures suivantes :

  • - la figure 1 est une vue schématique de côté d'une station d'introduction,
  • - la figure 2 est un diagramme schématique de l'avance, de la vitesse et de l'accélération d'une bande en relation avec des exemples de vitesses et d'accélérations périphériques du rouleau d'introduction en fonction du cycle de la station exprimées en degrés de rotation du moteur principal d'entraînement, et
  • - la figure 3 est une vue schématique en perspective d'un entraînement indépendant du rouleau d'introduction.
The invention will be better understood from the study of an embodiment taken by way of nonlimiting example and described by the following figures:
  • FIG. 1 is a schematic side view of an introduction station,
  • - Figure 2 is a schematic diagram of the advance, speed and acceleration of a strip in relation to examples of speeds and peripheral accelerations of the feed roller as a function of the station cycle expressed in degrees of rotation of the main drive motor, and
  • - Figure 3 is a schematic perspective view of an independent drive of the introduction roller.

Sur la figure 1 est illustrée une station d'introduction 10 recevant en amont une bande de matière 5 avec une vitesse constante VO, et délivrant en aval cette bande 5 avec une vitesse intermittente VIT à une presse à platine 20. Pour induire cette variation de vitesse, la bande 5 passe autour d'un rouleau 13 à faible inertie et monté de manière excentrée sur deux plateaux rotatifs latéraux. Ainsi, à chaque tour de plateaux, la bande forme une boucle de dimensions contrôlées, la vitesse de sortie étant quasiment nulle lors de la formation de cette boucle.In FIG. 1 is illustrated an introduction station 10 receiving upstream a strip of material 5 with a constant speed VO, and delivering downstream this strip 5 with an intermittent speed VIT to a platen press 20. To induce this variation in speed, the strip 5 passes around a roller 13 with low inertia and mounted eccentrically on two lateral rotary plates. Thus, at each turn of the plates, the strip forms a loop of controlled dimensions, the exit speed being almost zero during the formation of this loop.

La paire de rouleaux 11 impose une tension de bande pour le trajet amont, alors qu'un rouleau d'introduction 15, dirigeant la bande vers la presse à platine, maintient la tension dans la boucle grâce à des forces de friction du fait que sa vitesse périphérique VR reste en tout temps supérieure à la vitesse VIT momentanée de la bande.The pair of rollers 11 imposes a belt tension for the upstream path, while an introduction roller 15, directing the band towards the platen press, maintains the tension in the loop thanks to friction forces because its Peripheral speed VR remains at all times greater than the momentary speed VIT of the tape.

Comme mieux visible sur la figure 2, la progression AVIT de la bande à la sortie de la boucle n'est plus proportionnelle à l'entraînement général de la machine, mais, après avoir été nulle pendant la descente du rouleau excentré, se fait très rapidement lors de la remontée. La vitesse intermittente VIT de la bande suit donc un régime en forme de cloche optimisé en fonction des caractéristiques du matériau de la bande, régime dont la valeur moyenne sur le cycle correspond à la vitesse d'arrivée VO qui est usuellement de l'ordre de 3,5 m/s. La courbe ACIT représente le régime d'accélération correspondant comprenant une accélération jusqu'à environ 190 m/s2 puis une décélération de l'ordre de -255 m/s2.As best seen in Figure 2, the AVIT progression of the belt at the exit of the loop is no longer proportional to the general drive of the machine, but, after being zero during the descent of the eccentric roller, is very quickly during the ascent. The intermittent speed VIT of the strip therefore follows a bell-shaped regime optimized as a function of the characteristics of the material of the strip, a regime whose average value over the cycle corresponds to the arrival speed VO which is usually of the order of 3.5 m / s. The ACIT curve represents the corresponding acceleration regime comprising an acceleration to around 190 m / s2 then a deceleration of the order of -255 m / s2.

La valeur maximum de la vitesse intermittente VIT de la bande pouvant atteindre une valeur de l'ordre de 8,5 m/s, on impose dans les machines conventionnelles, une vitesse périphérique constante VRO du rouleau d'introduction supérieur de l'ordre de 9 m/s. La surface S1 marque l'importance de la différence de vitesse instantanée qui se traduit, de manière proportionnelle, en chaleur à dissiper.Since the maximum value of the intermittent speed VIT of the strip can reach a value of the order of 8.5 m / s, a conventional peripheral speed VRO of the upper feed roller of the order of 9 m / s. The surface S1 marks the importance of the instantaneous speed difference which translates, in a proportional manner, into heat to be dissipated.

Selon l'invention, et comme illustré sur la figure 3, le cylindre 13 est entraîné par un moteur électrique indépendant 35 au travers d'un réducteur constitué d'un double engrenage 40/42 et 44/46. Grâce à ce moteur 35, on entraîne le rouleau non plus à une vitesse constante, mais selon un régime VR1 ou VR2.According to the invention, and as illustrated in FIG. 3, the cylinder 13 is driven by an independent electric motor 35 through a reducer constituted by a double gear 40/42 and 44/46. Thanks to this motor 35, the roller is no longer driven at a constant speed, but according to a speed VR1 or VR2.

Selon le premier régime, la vitesse VR1 du rouleau d'introduction croît puis décroît de manière linéaire d'une valeur de 2 m/s à une valeur de 9,2 m/s, l'accélération puis le freinage ACR1 appliqués par le moteur étant constants.According to the first regime, the speed VR1 of the feed roller increases then decreases linearly from a value of 2 m / s to a value of 9.2 m / s, the acceleration then braking ACR1 applied by the motor being constant.

Selon le second régime, la vitesse VR2 du rouleau d'introduction évolue selon un régime en cloche plus proche du régime de vitesse VIT de la bande. L'accélération ACR2 passe alors par un maximum.According to the second regime, the speed VR2 of the introduction roller evolves according to a bell-shaped regime closer to the speed regime VIT of the strip. The acceleration ACR2 then passes through a maximum.

La surface S2 représente la différence de vitesse résiduelle entre la bande et le rouleau, réduite maintenant à une valeur optimisée pour conserver une tension suffisante dans la bande et pour minimiser les pertes de chaleur.The area S2 represents the residual speed difference between the strip and the roller, now reduced to an optimized value to maintain sufficient tension in the strip and to minimize heat loss.

L'évaluation du moment d'inertie du rouleau d'introduction 13 et de son dispositif d'entraînement se fait, de manière connue, de proche en proche en tenant compte du moment d'inertie de chacun des composants, à savoir du rouleau 13 avec son arbre de rotation 47, de la roue conique menée 46, de la roue conique menante 44, de l'arbre 45, de la roue dentée menée 42, de la roue dentée menante 40, de l'axe de sortie 36 et du moteur 35, et ce en tenant compte des rapports de réduction, par exemple de 15:38 au niveau des roues 44/46 et de 20:36 au niveau des roues 40/42. Le moment d'inertie total ramené au niveau du moteur 35 peut, typiquement, être de l'ordre de 0,03 kgm2, et en tous les cas inférieur à 0,04 kgm2.The moment of inertia of the introduction roller 13 and its drive device is evaluated, in known manner, step by step, taking into account the moment of inertia of each of the components, namely of the roller 13 with its rotation shaft 47, the driven bevel gear 46, the driving bevel gear 44, the shaft 45, the driven gear 42, the driving gear 40, the output axle 36 and the motor 35, and this taking account of the reduction ratios, for example 15:38 at the level of the wheels 44/46 and 20:36 at the level of the wheels 40/42. The total moment of inertia reduced to the level of the motor 35 can typically be of the order of 0.03 kgm2, and in any case less than 0.04 kgm2.

Le couple maximum nécessaire à fournir par le moteur est égal au produit du moment d'inertie par l'accélération angulaire maximum nécessaire.The maximum torque required by the motor is equal to the product of the moment of inertia by the maximum angular acceleration required.

A l'occasion d'une adaptation sur une machine existante, le couple de charge initialement prévu pour l'entraînement en continu du rouleau d'introduction sur le différentiel et la chaîne cinématique de l'entraînement général de la machine peut être compensé par un frein moteur. La balance d'énergie se fait alors via le réseau électrique.When adapting to an existing machine, the load torque initially planned for the continuous drive of the feed roller on the differential and the kinematic chain of the general drive of the machine can be compensated by a Engine brake. The energy balance is then made via the electrical network.

La consigne de vitesse selon un profil prédéterminé appliqué au moteur électrique peut se faire de manière connue par des moyens informatiques et électrotechniques.The speed reference according to a predetermined profile applied to the electric motor can be done in a known manner by computer and electrotechnical means.
