Abstract

The printing machine has a continuous conveyor (11) with a series of holders (13) for the articles to be printed, at least one silk screen printer (14) in line with the trajectory of the holders, and incorporates at least one digital ink jet printer (15) which comes into operation on demand. The silk screen printer can be moved to a second position away from the trajectory of the holders, allowing the ink-jet printer to slide into its place on guide rails (20) mounted on a separate frame (21).

Description

La présente invention concerne d'une manière générale les machines à imprimer du genre comportant un convoyeur sans fin qui porte, de place en place, une pluralité de supports porte-objet, et au moins un poste d'impression sérigraphique, qui, disposé à l'aplomb du trajet des supports porte-objet, est apte à assurer tour à tour l'impression des objets portés par ceux-ci.The present invention relates generally to machines for print of the kind with an endless conveyor that carries, from place to place place, a plurality of object holders, and at least one printing station serigraphic, which, placed directly above the path of the object-holder, is able to ensure in turn the printing of the objects carried by them.

Les postes d'impression sérigraphique ont de nombreux avantages, qui les font apprécier pour l'impression d'articles très divers, et, par exemple, pour celle de disques compacts.Screen printing stations have many advantages, which make them appreciated for printing a wide variety of articles, and, for example, for that of compact discs.

En particulier, ils sont avantageusement susceptibles de cadences de travail relativement élevées, de l'ordre par exemple d'un disque compact par seconde, parce que, l'écran de soie qu'ils mettent en oeuvre s'appliquant par lui-même à l'ensemble de la surface à imprimer, ils concernent d'emblée la totalité de celle-ci.In particular, they are advantageously susceptible of rates of relatively high work, of the order for example of a compact disc by second, because, the silk screen that they are implementing applying by itself to the entire surface to be printed, they immediately concern the whole of it.

Ils conviennent donc tout particulièrement lorsque le nombre d'articles à imprimer en série est relativement important, en étant par exemple supérieur à mille.They are therefore particularly suitable when the number of articles to be printing in series is relatively important, for example being greater than thousand.

Les postes d'impression sérigraphique ont cependant pour inconvénient de nécessiter, avant leur mise en route, un réglage en position de leur écran de soie, pour ajuster la position de l'impression assurée par celui-ci par rapport à la surface à imprimer, et, le cas échéant, c'est-à-dire lorsque doit intervenir un changement de couleur, le nettoyage de la raclette et de la contre-raclette associées à cet écran de soie.The disadvantages of screen printing stations to require, before starting up, an adjustment in position of their screen silk, to adjust the position of the printing provided by it relative to the surface to be printed, and, if necessary, that is to say when a color change, cleaning the squeegee and counter squeegee associated with this silk screen.

Le temps de mise en route correspondant peut par exemple atteindre plusieurs minutes.The corresponding start-up time can for example reach several minutes.

Par suite, lorsque, comme cela est le cas fréquent, plusieurs postes d'impression sérigraphique sont à mettre en oeuvre pour l'impression d'un même article, à raison d'un poste d'impression sérigraphique par couleur à appliquer à celui-ci, le temps global d'utilisation de la machine à imprimer devient très largement supérieur à son temps réel d'impression, en étant par exemple trois à quatre fois supérieur à celui-ci, au détriment de la productivité. Consequently, when, as is often the case, several posts screen printing are to be implemented for the printing of a same article, at the rate of one screen printing station per color at apply to it the overall time of use of the printing machine greatly exceeds its actual printing time, by being example three to four times higher than this, at the expense of productivity.

La présente invention a d'une manière générale pour objet une disposition de nature à permettre de minimiser cet inconvénient.The present invention generally relates to a provision likely to minimize this drawback.

De manière plus précise, elle a pour objet une machine à imprimer du genre comportant un convoyeur sans fin, qui porte, de place en place, une pluralité de supports porte-objet, et au moins un poste d'impression sérigraphique disposé à l'aplomb du trajet de ces supports porte-objet, cette machine à imprimer étant d'une manière générale caractérisée en ce qu'elle comporte, également, au moins un poste d'impression numérique, qui fonctionne par jet d'encre, et qui est destiné à intervenir à la demande.More specifically, it relates to a machine for printing kind comprising an endless conveyor, which carries, from place to place, a plurality of object holders, and at least one printing station screen printing positioned directly above the path of these object holders, this printing machine being generally characterized in that it also includes at least one digital printing station, which works by inkjet, and which is intended to intervene on demand.

Les postes d'impression numérique fonctionnant par jet d'encre sont bien connus par eux-mêmes, et ils ont pour avantages, d'une part, d'opérer directement, sans faire appel à un quelconque accessoire, tel qu'écran, cliché ou autre, et en permettant donc de faire l'économie d'un tel accessoire, et, d'autre part, de pouvoir assurer, par eux-mêmes, l'impression de plusieurs couleurs, sans nécessiter de réglage spécifique pour chacune de celles-ci.The inkjet-operated digital printing stations are well known by themselves, and they have the advantages, on the one hand, of operating directly, without using any accessory, such as screen, photo or other, and thus allowing to save such an accessory, and, on the other hand, to be able to ensure, by themselves, the impression of several colors, without requiring any specific adjustment for each of these.

Il suffit, en effet, qu'ils comportent autant de buses d'impression qu'il y a de couleurs à imprimer, et que, dûment programmée à cet effet, leur commande assure de manière contrôlée l'intervention de chacune de ces buses d'impression.It suffices, in fact, that they have as many print nozzles as there are has colors to print, and that, duly programmed for this purpose, their control ensures in a controlled way the intervention of each of these nozzles printing.

Mais, opérant point par point, et ligne par ligne, les postes d'impression numérique fonctionnant par jet j'encre ont pour inconvénient de n'être susceptibles que de cadences de travail relativement faibles, très inférieures, en tout cas, à celle d'un poste d'impression sérigraphique.But, operating point by point, and line by line, the printing stations jet-operated digital ink have the disadvantage of not being likely only for relatively low, much lower work rates, in any case, that of a screen printing station.

Cependant, dès que le nombre d'articles à imprimer en série est relativement faible, en étant par exemple inférieur à mille, la productivité d'une machine à imprimer mettant en oeuvre un tel poste d'impression numérique fonctionnant par jet d'encre devient concurrentielle avec celle d'une machine à imprimer mettant en oeuvre un poste d'impression sérigraphique, et il en est ainsi a fortiori si, comme cela est le cas le plus fréquent, plusieurs couleurs sont à imprimer sur un même article. However, as soon as the number of articles to be printed in series is relatively low, for example being less than a thousand, the productivity of a printing machine using such a digital printing station inkjet becomes competitive with that of a print using a screen printing station, and so is thus a fortiori if, as is the most frequent case, several colors are to be printed on the same article.

En permettant à l'utilisateur de la machine à imprimer suivant l'invention de faire intervenir à son gré, suivant les nécessités du moment, et, plus précisément, suivant le nombre d'articles à imprimer, un poste d'impression numérique fonctionnant par jet d'encre, en le substituant par exemple à un poste d'impression sérigraphique, la disposition suivant l'invention conduit avantageusement au maintien d'une productivité acceptable pour cette machine à imprimer, même lorsque le nombre d'articles à imprimer est relativement faible.By allowing the user of the printing machine according to the invention to intervene at will, according to the needs of the moment, and, more precisely, depending on the number of articles to be printed, a printing station digital inkjet operation, substituting for example a screen printing station, the arrangement according to the invention leads advantageously to maintaining an acceptable productivity for this printing machine, even when the number of articles to be printed is relatively small.

En outre, cette disposition, qui associe un poste d'impression numérique fonctionnant par jet d'encre à un poste d'impression sérigraphique, est d'autant plus avantageuse que, l'impression par jet d'encre nécessitant la présence, sur les objets à imprimer, d'une couche de matière absorbante ou de vernis, cette couche de matière absorbante ou de vernis peut aisément être appliquée à ces objets à un poste d'impression sérigraphique.In addition, this arrangement, which combines a digital printing station operating by inkjet at a screen printing station, is all the more advantageous since inkjet printing requiring the presence on the objects to be printed of a layer of absorbent material or varnish, this layer of absorbent material or varnish can easily be applied to these objects at a screen printing station.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

  • la figure 1 est une vue en perspective d'une machine à imprimer suivant l'invention ;
  • la figure 2 est, à échelle supérieure, une vue en perspective du poste d'impression numérique fonctionnant par jet d'encre qu'elle comporte ;
  • la figure 3 est une vue partielle de dessus de ce poste numérique, suivant la flèche III de la figure 2, et avec une partie du convoyeur sans fin associé ;
  • les figures 4A, 4B sont des vues en perspective qui, analogues à celle de la figure 1, illustrent deux phases successives de mise en oeuvre de cette machine à imprimer.
    • The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:
  • Figure 1 is a perspective view of a printing machine according to the invention;
  • Figure 2 is, on a larger scale, a perspective view of the digital printing station operating by ink jet it comprises;
  • Figure 3 is a partial top view of this digital station, along arrow III of Figure 2, and with a portion of the associated endless conveyor;
  • Figures 4A, 4B are perspective views which, similar to that of Figure 1, illustrate two successive stages of implementation of this printing machine.

    • Tel qu'illustré sur ces figures, la machine à imprimer 10 suivant l'invention comporte, globalement, de manière connue en soi, un convoyeur sans fin 11, qui porte, de place en place, une pluralité de supports porte-objet 13, et au moins un poste d'impression sérigraphique 14 disposé à l'aplomb du trajet de ces supports porte-objet 13.As illustrated in these figures, the following printing machine 10 the invention comprises, overall, in a manner known per se, a conveyor endless 11, which carries, from place to place, a plurality of object holders 13, and at least one screen printing station 14 disposed directly above the path of these object holders 13.

    Cette machine à imprimer 10 ne relevant pas, par elle-même, de la présente invention, elle ne sera pas décrite dans tous ses détails ici.This printing machine 10 does not, by itself, fall under the present invention, it will not be described in all its details here.

    Il en est ainsi, en particulier, du convoyeur sans fin 11, des supports porte-objet 13, et du poste d'impression sérigraphique 14, et c'est en outre la raison pour laquelle ce convoyeur sans fin 11, ces supports porte-objet 13, et ce poste d'impression sérigraphique 14, n'ont été que schématisés, par leur contour, sur les figures.This is particularly the case with the endless conveyor 11, the supports object holder 13, and screen printing station 14, and it is also the reason why this endless conveyor 11, these object holders 13, and this screen printing station 14, were only shown schematically, by their outline, in the figures.

    S'agissant, par exemple, du convoyeur sans fin 11, il suffira d'indiquer que, dans la forme de réalisation représentée, il est formé, à titre d'exemple, par un plateau de contour circulaire monté rotatif sur un bâti 12, à la manière d'une tourelle, et que les supports porte-objet 13 qu'il porte sont répartis circulairement à un pas régulier autour de l'axe de rotation A de ce plateau.As for example, the endless conveyor 11, it will suffice to indicate that, in the embodiment shown, it is formed, by way of example, by a circular contour plate rotatably mounted on a frame 12, in the manner of a turret, and that the object-carrying supports 13 which it carries are distributed circularly at a regular pitch around the axis of rotation A of this plate.

    S'agissant du poste d'impression sérigraphique 14, il suffira, corollairement, de rappeler que, de manière connue en soi, il met en oeuvre un écran de soie formant pochoir, dont certaines des mailles sont libres et d'autres obturées, suivant l'impression à assurer, et que, à cet écran de soie, est associée une raclette, qui, montée mobile à cet effet, est apte, notamment, à forcer de l'encre à passer à travers ses mailles libres.Regarding the screen printing station 14, it will suffice, as a corollary, to recall that, in a manner known per se, it implements a silk screen forming a stencil, some of which are free and others closed, according to the impression to be made, and that, on this silk screen, is associated with a squeegee, which, mounted mobile for this purpose, is suitable, in particular, to force ink to pass through its free meshes.

    En pratique, plusieurs postes d'impression sérigraphique 14 sont répartis autour du convoyeur sans fin 11, à raison d'un poste d'impression sérigraphique 14 par couleur à appliquer aux articles à imprimer.In practice, several screen printing stations 14 are distributed around the endless conveyor 11, at a printing station serigraphic 14 by color to be applied to the articles to be printed.

    Par mesure de simplicité, seuls deux postes d'impression sérigraphique 14 ont été schématisés sur les figures.For simplicity, only two screen printing stations 14 have been shown diagrammatically in the figures.

    En pratique, également, à chacun des postes d'impression sérigraphique 14 ainsi mis en oeuvre est usuellement associé un poste de séchage, non représenté.In practice, too, at each screen printing station 14 thus implemented is usually associated with a drying station, not represented.

    D'autres postes, également non représentés, peuvent aussi être prévus le long du convoyeur sans fin 11, tels que, par exemple, un poste de chargement et/ou de déchargement, un poste de dépoussiérage, et un poste de flammage.Other positions, also not shown, can also be provided along the endless conveyor 11, such as, for example, a loading and / or unloading, a dusting station, and a station flaming.

    Suivant l'invention, la machine à imprimer 10 comporte, également, au moins un poste d'impression numérique 15, qui fonctionne par jet d'encre, et qui est destiné à intervenir à la demande.According to the invention, the printing machine 10 also comprises, at minus a digital printing station 15, which operates by inkjet, and which is intended to intervene on demand.

    Par exemple, et cela est le cas dans la forme de réalisation représentée, ce poste d'impression numérique 15 est associé à un poste d'impression sérigraphique 14, et il est apte à être substitué à celui-ci.For example, and this is the case in the embodiment shown, this digital printing station 15 is associated with a printing station serigraphic 14, and it is able to be substituted for this one.

    Dans la forme de réalisation représentée, le poste d'impression sérigraphique 14 auquel est ainsi associé un poste d'impression numérique 15 est escamotable.In the embodiment shown, the printing station screen printing 14 with which is thus associated a digital printing station 15 is retractable.

    Les postes d'impression sérigraphique 14 autres que celui auquel le poste d'impression numérique 15 peut être substitué ne sont pas, eux, nécessairement escamotables.Screen printing stations 14 other than that to which the digital printing station 15 can be substituted are not they necessarily retractable.

    Mais certains au moins d'entre eux peuvent l'être si désiré.But at least some of them can be if desired.

    Dans la forme de réalisation représentée, le poste d'impression sérigraphique 14 auquel est associé le poste d'impression numérique 15 est monté mobile entre une position de service, qui est relativement proche du convoyeur sans fin 11, et pour laquelle il est apte à intervenir, figure 1, et une position d'attente, qui est relativement éloignée du convoyeur sans fin 11, et pour laquelle il laisse entre celui-ci et lui un espace 16 suffisant pour que le poste d'impression numérique 15 puisse être implanté à sa place, figures 4A et 4B.In the embodiment shown, the printing station screen printing 14 with which the digital printing station 15 is associated mounted movable between a service position, which is relatively close to the endless conveyor 11, and for which it is capable of operating, FIG. 1, and a standby position, which is relatively far from the endless conveyor 11, and for which he leaves between him and him sufficient space 16 for the digital printing station 15 can be installed in its place, FIGS. 4A and 4B.

    En pratique, dans la forme de réalisation représentée, le poste d'impression sérigraphique 14 est monté coulissant sur au moins une colonne 18, qui s'étend sensiblement perpendiculairement au convoyeur sans fin 11.In practice, in the embodiment shown, the station 14 is slidably mounted on at least one column 18, which extends substantially perpendicular to the endless conveyor 11.

    Par exemple, et tel que représenté, deux colonnes 18 sont prévues, parallèlement l'une à l'autre, à distance l'une de l'autre.For example, and as shown, two columns 18 are provided, parallel to each other, at a distance from each other.

    Corollairement, le poste d'impression numérique 15 est globalement monté mobile entre une position d'attente, pour laquelle il est écarté du convoyeur sans fin 11, figures 1 et 4A, et une position de service, pour laquelle, en substitution au poste d'impression sérigraphique 14, il est à l'aplomb du trajet des supports porte-objet 13 portés par ce convoyeur sans fin 11, figure 4B.As a corollary, digital printing station 15 is globally mounted movable between a standby position, for which it is moved away from the endless conveyor 11, Figures 1 and 4A, and a service position, for which, in substitution for the screen printing station 14, it is vertical to the path of the object holders 13 carried by this conveyor without end 11, figure 4B.

    En pratique, dans la forme de réalisation représentée, le poste d'impression numérique 15 est monté coulissant sur au moins un rail 20, qui s'étend sensiblement parallèlement au convoyeur sans fin 11.In practice, in the embodiment shown, the station digital printing device 15 is slidably mounted on at least one rail 20, which extends substantially parallel to the endless conveyor 11.

    Par exemple, et tel que représenté sur la figure 1, deux rails 20 sont prévus, parallèlement l'un à l'autre, à distance l'un de l'autre.For example, and as shown in FIG. 1, two rails 20 are provided, parallel to each other, at a distance from each other.

    Dans la forme de réalisation représentée, le poste d'impression numérique 15 est porté par un bâti 21 indépendant, c'est-à-dire par un bâti 21 distinct du bâti 12 portant le convoyeur sans fin 11 et le poste d'impression sérigraphique 14.In the embodiment shown, the printing station digital 15 is carried by an independent frame 21, that is to say by a frame 21 separate from the frame 12 carrying the endless conveyor 11 and the printing station screen printing 14.

    Par exemple, et tel que représenté, ce bâti 21 est équipé de roulettes 22, pour son approche du bâti 12, et les rails 20, qui sont portés par ce bâti 21, permettent si nécessaire un ajustement plus fin de la position du poste d'impression numérique 15 par rapport au bâti 12, sensiblement parallèlement au convoyeur sans fin 11.For example, and as shown, this frame 21 is equipped with rollers 22, for its approach to the frame 12, and the rails 20, which are carried by this frame 21, allow if necessary a finer adjustment of the position of the station digital printing 15 relative to the frame 12, substantially parallel to the endless conveyor 11.

    Dans la forme de réalisation représentée, le poste d'impression numérique 15 est en outre monté réglable en position sensiblement perpendiculairement au convoyeur sans fin 11.In the embodiment shown, the printing station digital 15 is further mounted adjustable in position substantially perpendicular to the endless conveyor 11.

    Plus précisément, dans cette forme de réalisation, il est monté coulissant sur au moins un montant 24, qui s'étend sensiblement perpendiculairement au convoyeur sans fin 11, et qui est porté par un chariot 25 monté mobile sur les rails 20.More specifically, in this embodiment, it is mounted sliding on at least one upright 24, which extends substantially perpendicular to the endless conveyor 11, which is carried by a carriage 25 mounted mobile on the rails 20.

    Par exemple, et tel que représenté sur la figure 1, deux montants 24 sont prévus, parallèlement l'un à l'autre, à distance l'un de l'autre.For example, and as shown in FIG. 1, two uprights 24 are provided, parallel to each other, at a distance from each other.

    Dans la forme de réalisation représentée, le poste d'impression numérique 15 comporte une traverse 27, qui, à la manière d'une table X-Y, est montée mobile suivant deux directions D1, D2 orthogonales, tel que schématisé par des doubles flèches sur la figure 2, et qui porte au moins une tête d'impression 28. In the embodiment shown, the printing station digital 15 has a cross 27, which, like an X-Y table, is movable climb in two orthogonal directions D1, D2, such that shown schematically by double arrows in Figure 2, and which carries at least one print head 28.

    En pratique, l'une des directions D1, D2 de mobilité de cette traverse 27, en l'espèce la direction D1, est sensiblement tangentielle par rapport au plateau formant le convoyeur sans fin 11, et l'autre, et, donc, en l'espèce, la direction D2, est sensiblement radiale par rapport à celui-ci.In practice, one of the directions D1, D2 of mobility of this cross 27, in this case the direction D1, is substantially tangential to the plate forming the endless conveyor 11, and the other, and, therefore, in this case, the direction D2, is substantially radial with respect to the latter.

    En pratique, la traverse 27 du poste d'impression numérique 15 est montée coulissante sur au moins une coulisse 29 qui appartient à un chariot 30 monté lui-même coulissant sur au moins une coulisse 31 orthogonale à la coulisse 29 précédente.In practice, the cross 27 of the digital printing station 15 is sliding mounted on at least one slide 29 which belongs to a carriage 30 mounted itself sliding on at least one slide 31 orthogonal to the backstage 29 previous.

    Par exemple, et tel que représenté sur la figure 2, deux coulisses 29 sont prévues, parallèlement l'une à l'autre, à distance l'une de l'autre, et, de même, mais en positions croisées par rapport aux coulisses 29, et à distance de celles-ci, deux coulisses 31 sont prévues, parallèlement l'une à l'autre, à distance l'une de l'autre.For example, and as shown in FIG. 2, two slides 29 are provided, parallel to each other, at a distance from each other, and, from same, but in crossed positions relative to the slides 29, and at a distance of these, two slides 31 are provided, parallel to each other, at distance from each other.

    Par exemple, également, le chariot 30 est en quelque sorte suspendu aux coulisses 31, et la traverse 27 porte sur les coulisses 29.For example, also, the carriage 30 is somehow suspended behind the scenes 31, and the cross member 27 bears on the slides 29.

    Préférentiellement, la traverse 27 est en prise, par un écrou 32, avec une vis 33 calée sur l'arbre de sortie d'un moteur 34, et, de même, le chariot 30 est en prise, par un écrou 35, avec une vis 36 calée sur l'arbre de sortie d'un moteur 37.Preferably, the cross member 27 is engaged, by a nut 32, with a screw 33 wedged on the output shaft of a motor 34, and, similarly, the carriage 30 is engaged, by a nut 35, with a screw 36 wedged on the output shaft an engine 37.

    Dans la forme de réalisation représentée, la traverse 27 du poste d'impression numérique 15 s'étend sensiblement tangentiellement par rapport au plateau formant le convoyeur sans fin 11, suivant la direction D1.In the embodiment shown, the cross member 27 of the station digital printing 15 extends substantially tangentially relative to to the plate forming the endless conveyor 11, in the direction D1.

    Elle s'étend donc sensiblement perpendiculairement par rapport à ce convoyeur sans fin 11.It therefore extends substantially perpendicular to this endless conveyor 11.

    Préférentiellement, cette traverse 27 porte au moins deux têtes d'impression 28, qui sont échelonnées suivant sa longueur, et qui sont décalées transversalement l'une par rapport à l'autre suivant sa largeur, de manière à tenir compte du rayon de la circonférence suivant laquelle s'étendent les supports porte-objet 13.Preferably, this crosspiece 27 carries at least two heads 28, which are staggered along its length, and which are offset transversely relative to each other along its width, by so as to take into account the radius of the circumference along which the object holders 13 extend.

    Par exemple, et tel que représenté, la traverse 27 porte ainsi, à distance l'une de l'autre, quatre têtes d'impression 28, et celles-ci sont établies suivant un pas qui correspond sensiblement au pas des supports porte-objet 13 sur le convoyeur sans fin 11.For example, and as shown, the cross member 27 thus carries, at a distance one from the other, four printheads 28, and these are established according to a pitch which corresponds substantially to the pitch of the object-holder supports 13 on the endless conveyor 11.

    Dans la forme de réalisation représentée, les têtes d'impression 28 interviennent à la manière de nacelles à la surface inférieure de la traverse 27, et chacune d'elles porte, elle-même, sur sa propre surface inférieure, au moins deux buses d'impression 39.In the embodiment shown, the print heads 28 intervene in the manner of nacelles on the lower surface of the cross member 27, and each of them carries, itself, on its own lower surface, at least two print nozzles 39.

    En pratique, et tel que représenté, quatre buses d'impression 39, au moins, sont ainsi échelonnées sur chacune des têtes d'impression 28, suivant la longueur de celles-ci, pour répondre aux exigences d'une impression en quadrichromie.In practice, and as shown, four print nozzles 39, at less, are thus staggered on each of the print heads 28, according to the length of these, to meet the requirements of a printing in full color.

    Ces buses d'impression 39 sont bien connues par elles-mêmes, notamment sur les imprimantes du commerce, et, ne relevant donc pas, en propre, de la présente invention, elles ne seront pas décrites ici.These print nozzles 39 are well known in themselves, especially on commercial printers, and therefore not relevant, in clean, of the present invention, they will not be described here.

    Enfin, dans la forme de réalisation représentée, le chariot 30 du poste d'impression numérique 15 comporte, à l'une des extrémités des coulisses 29, un boítier 40, pour le logement d'un dispositif de nettoyage propre à assurer le nettoyage des buses d'impression 39.Finally, in the embodiment shown, the carriage 30 of the station digital printing 15 comprises, at one of the ends of the slides 29, a housing 40, for housing a clean cleaning device to ensure the cleaning the print nozzles 39.

    Les dispositions correspondantes sont elles aussi bien connues par elles-mêmes, notamment sur les imprimantes du commerce, et, ne relevant pas en propre de la présente invention, elles ne seront pas non plus décrites ici.The corresponding provisions are also well known in themselves, especially on commercial printers, and, not falling under specific to the present invention, they will not be described here either.

    En fonctionnement normal, le poste d'impression sérigraphique 14 est en position de service, et le poste d'impression numérique 15 est en position d'attente.In normal operation, the screen printing station 14 is in service position, and digital printing station 15 is in position waiting.

    Si nécessaire, et tel que schématisé à la figure 4A, le poste d'impression sérigraphique 14 est élevé en position d'attente, et, à sa place, est inséré, sous lui, dans l'espace 16 qu'il laisse libre entre lui et le convoyeur sans fin 11, le poste d'impression numérique 15, tel que représenté à la figure 4B.If necessary, and as shown in FIG. 4A, the printing station silkscreen 14 is raised in the waiting position, and, in its place, is inserted, under him, in the space 16 which he leaves free between him and the endless conveyor 11, the digital printing station 15, as shown in FIG. 4B.

    Ainsi qu'on le notera, lorsqu'il est ainsi en service, le poste d'impression numérique 15 prévu suivant l'invention coopère avec au moins deux supports porte-objet 13, et, en l'espèce, avec quatre, à raison d'un support porte-objet 13 par tête d'impression 28, en intervenant simultanément sur les objets à imprimer portés par ces supports porte-objet 13, tandis qu'un poste d'impression sérigraphique 14 ne coopère, lui, qu'avec un seul support porte-objet 13.As will be noted, when so in use, the printing station digital device 15 according to the invention cooperates with at least two supports object holder 13, and in this case with four, at the rate of an object holder 13 per print head 28, acting simultaneously on the objects to be print carried by these object holders 13, while a post 14 only cooperates with one support object holder 13.

    Il est ainsi avantageusement possible de rapprocher la cadence d'impression par jet d'encre de la cadence d'impression par sérigraphie.It is thus advantageously possible to bring the rate closer inkjet printing of the screen printing rate.

    Ainsi qu'on le notera, également, lorsque le poste d'impression numérique 15 est en service, il intervient, simultanément, avec au moins un autre poste d'impression sérigraphique 14, si, comme envisagé ci-dessus, la machine à imprimer 10 comporte un ou plusieurs postes d'impression sérigraphique 14 en sus de celui auquel est associé ce poste d'impression numérique 15.As will also be noted, when the printing station digital 15 is in service, it intervenes simultaneously with at least one another screen printing station 14, if, as envisaged above, the printing machine 10 has one or more printing stations screen printing 14 in addition to the one associated with this printing station digital 15.

    Or, comme déjà souligné précédemment, la cadence de travail de ces postes d'impression sérigraphique 14 est supérieure à celle du poste d'impression numérique 15, ce qui, normalement, les conduit, à chaque avance d'un pas du convoyeur sans fin 11, à s'arrêter avant le poste d'impression numérique 15.However, as already pointed out previously, the pace of work of these screen printing stations 14 is greater than that of the station digital printing 15, which normally leads them to each one step forward of the endless conveyor 11, to stop before the post digital printing 15.

    Suivant un développement de l'invention, des moyens de modulation sont prévus pour permettre, ainsi, effectivement, au poste d'impression numérique 15 d'intervenir, au moins momentanément, simultanément avec au moins un autre poste d'impression sérigraphique 14.According to a development of the invention, modulation means are provided to allow, thus, effectively, to the printing station digital 15 to intervene, at least momentarily, simultaneously with at minus another screen printing station 14.

    Par exemple, ces moyens de modulation résultent, notamment, de ce que les moyens de commande du ou des postes d'impression sérigraphique 14 sont découplés des moyens de commande du convoyeur sans fin 11.For example, these modulation means result, in particular, from this that the control means of the screen printing station (s) 14 are decoupled from the control means of the endless conveyor 11.

    En variante, ou en complément, ces moyens de modulation résultent, notamment, de ce que les moyens de commande du ou des postes d'impression sérigraphique 14 et les moyens de commande du poste d'impression numérique 15 sont distincts.As a variant, or in addition, these modulation means result, in particular, that the control means of the station (s) screen printing 14 and the station control means digital printing 15 are separate.

    Corollairement, suivant un autre développement de l'invention, les moyens de commande du convoyeur sans fin 11 sont préférentiellement à vitesse variable, pour permettre une impression en sérigraphie à cadence normale lorsque cela est possible, et une impression par jet d'encre à cadence plus lente lorsque cela est nécessaire.As a corollary, according to another development of the invention, the control means of the endless conveyor 11 are preferably to variable speed, to allow screen printing at cadence normal when possible, and inkjet printing at a rate slower when necessary.

    Les modalités de réalisation de tels moyens de modulation relevant de l'homme de l'art, elles ne seront pas décrites ici.The methods of implementing such modulation means falling under skilled in the art, they will not be described here.

    D'une manière plus générale, et ainsi qu'on l'aura compris, la machine à imprimer suivant l'invention est susceptible de relever de modalités d'exécution très diverses.More generally, and as will be understood, the printing according to the invention is likely to come under execution methods very diverse.

    Cela est d'ailleurs la raison pour laquelle le mode de réalisation plus particulièrement évoqué n'a pas été décrit dans tous ses détails ici, ceux-ci relevant simplement de l'homme de l'art.This is, moreover, the reason why the embodiment more particularly mentioned has not been described in all its details here, these simply within the skill of the art.

    La présente invention ne se limite de toute façon pas à ce mode de réalisation, mais s'étend au contraire à toute variante d'exécution.The present invention is not limited in any case to this mode of realization, but extends on the contrary to any variant of execution.

    En particulier, il peut être associé, au poste d'impression numérique fonctionnant par jet d'encre, un ou plusieurs autres postes, tels que, par exemple, au moins un poste de vernissage, par exemple un poste d'impression sérigraphique, et au moins un poste de séchage.In particular, it can be associated with the digital printing station operating by inkjet, one or more other stations, such as, for example, at least one varnishing station, for example a printing station screen printing, and at least one drying station.

    En outre, la configuration du convoyeur sans fin mis en oeuvre est indifférente.In addition, the configuration of the endless conveyor used is indifferent.

    Par exemple il pourrait tout aussi bien s'agir d'un convoyeur sans fin linéaire.For example it could just as easily be an endless conveyor linear.
