Description

La présente invention concerne un encrier pour machine d'impression ayant un fond avec un porte-lame dans lequel ledit porte-lame comporte plusieurs secteurs adjacents et déplaçables par des moyens de réglage pour varier la distance entre lesdits secteurs et la circonférence d'un cylindre d'encrier.The present invention relates to a machine ink fountain having a bottom with a blade holder in which said blade holder has several adjacent sectors and movable by adjustment means to vary the distance between those sectors and the circumference of a inkwell cylinder.

Ces lames et encriers sont utilisés principalement dans les machines d'impression taille-douce, dans lesquelles la quantité d'encre qui est appliquée sur le cylindre d'encrier est importante pour encrer convenablement les tailles des plaques d'impression.These blades and inkwells are used mainly in intaglio printing machines in which the amount of ink that is applied to the cylinder inkwell is important to properly ink sizes of printing plates.

Des lames d'encriers et des encriers de ce type sont connus dans l'état de la technique. Par exemple, le brevet DD 110 632 montre un encrier dont le fond comporte une lame qui est proche de la circonférence du cylindre d'encrier. Afin de varier la distance entre l'arête de la lame et le cylindre, c'est-à-dire l'épaisseur d'encre appliquée sur le cylindre, la lame est déformée de manière élastique par des vis qui s'appliquent contre la lame, de l'autre côté de celle-ci par rapport au cylindre d'encrier.Inkwell slides and inkwells of this type are known in the state of the art. For example, the DD 110 patent 632 shows an inkwell whose bottom has a blade which is close to the circumference of the inkwell cylinder. To to vary the distance between the edge of the blade and the cylinder, that is to say the thickness of ink applied to the cylinder, the blade is elastically deformed by screws that apply against the blade, on the other side of this one with respect to the inkwell cylinder.

L'inconvénient majeur de ce système réside dans le fait que la déformation de la lame ne permet pas l'application d'une épaisseur constante d'encre. En effet, le profil de la lame déformée, de manière schématique, a une forme arrondie puisque les vis s'appliquent à un endroit ponctuel de la lame, de sorte que le dosage de l'encre est en fait imprécis. The major drawback of this system lies in the fact that deformation of the blade does not allow the application of a constant thickness of ink. Indeed, the profile of the blade distorted, schematically, has a rounded shape since the screws apply to a specific spot of the blade, so that the dosage of the ink is actually imprecise.

Un autre système est décrit dans la demande de brevet EP 0 600 435. Dans ce système, la lame de l'encrier est formée par plusieurs lamelles adjacentes qui peuvent être déformées élastiquement afin de modifier l'épaisseur de l'encre appliquée sur le cylindre de l'encrier. Pour obtenir cette déformation, on agit dans ce cas aussi par l'intermédiaire d'un levier de l'autre côté des lamelles par rapport au cylindre d'encrier pour les rapprocher de celui-ci et ainsi modifier la distance entre l'arête de chaque lamelle et la circonférence du cylindre de l'encrier et, par conséquent, l'épaisseur de l'encre appliquée.Another system is described in patent application EP 0 600 435. In this system, the blade of the inkwell is formed by several adjacent lamellae that can be elastically deformed in order to modify the thickness of the ink applied to the cylinder of the inkwell. For to obtain this deformation, we act in this case also by via a lever on the other side of the slats compared to the inkwell cylinder to bring them closer to this one and so change the distance between the edge of each lamella and the circumference of the cylinder of the inkwell and, therefore, the thickness of the applied ink.

Ce système présente plusieurs inconvénients, notamment le fait que la déformation des lamelles se produit en direction du cylindre de l'encrier. Ainsi, en cas d'erreur de manipulation, il y a un risque que la lame entre en contact avec le cylindre et l'endommage. La déformation des lames entraíne également une fatigue du matériau qui peut créer des problèmes d'usure prématurée.This system has several disadvantages, including fact that the deformation of the lamellae occurs in direction of the cylinder of the inkwell. So, in case of error of manipulation, there is a risk that the blade will enter contact with the cylinder and damage. The deformation of blades also causes fatigue of the material that can create problems of premature wear.

Un autre système est connu de la demande de brevet EP 1 031 419. La lame de fond d'encrier décrite à la particularité d'être formée par des secteurs déplaçables dans le plan de la lame parallèlement les uns par rapport aux autres et de façon indépendante.Another system is known from patent application EP 1 031 419. The inkwell bottom blade described in the peculiarity to be formed by movable sectors in the plane of the blade parallel to each other and to independently.

D'autres systèmes sont connus dans l'état de la technique, notamment des publications DE 82 08 651.6, DE 35 03 736, DE 29 51 653, EP 0 046 206 et FR 419 472.Other systems are known in the state of the art, in particular publications DE 82 08 651.6, DE 35 03 736, DE 29 51 653, EP 0 046 206 and FR 419 472.

Le but de l'invention est d'améliorer les systèmes connus. The object of the invention is to improve the known systems.

Plus particulièrement, le but de l'invention est de proposer une lame et un encrier qui permettent un meilleur dosage de l'encre.More particularly, the object of the invention is to propose a blade and an inkwell that allow a better dosing the ink.

Un autre but de l'invention est de proposer une lame et un encrier qui produisent un encrage de qualité.Another object of the invention is to propose a blade and a inkwell that produce an inking quality.

Un autre but de l'invention est de fournir un encrier dont les éléments peuvent facilement être démontés et échangés en cas d'usure.Another object of the invention is to provide an inkwell which the elements can easily be dismantled and exchanged in case of wear.

A cet effet, l'invention est définie par les caractéristiques des revendications.For this purpose, the invention is defined by features of the claims.

La présente invention sera mieux comprise par la description de deux modes d'exécution de celle-ci et de dessins illustrant ces modes à titre d'exemples non-limitatifs.The present invention will be better understood by the description of two modes of execution of this one and drawings illustrating these modes as non-limiting examples.

La figure 1 montre une vue en perspective de dessus d'un encrier selon un premier mode d'exécution de l'invention.Figure 1 shows a perspective view from above of a inkwell according to a first embodiment of the invention.

La figure 2 montre une vue en perspective de côté d'un encrier selon un premier mode d'exécution de l'invention.Figure 2 shows a side perspective view of a inkwell according to a first embodiment of the invention.

La figure 3 montre une vue latérale en perspective d'un deuxième mode d'exécution de l'invention et état partiellement monté.Figure 3 shows a perspective side view of a second embodiment of the invention and state partially mounted.

La figure 4 montre une vue latérale en perspective d'un deuxième mode d'exécution de l'invention en état monté. Figure 4 shows a perspective side view of a second embodiment of the invention in mounted state.

Dans le premier mode d'exécution représenté à la figure 1, l'encrier comporte un porte-lame 1 ayant des secteurs 2 contigus qui permettent, par leur position relativement au cylindre d'encrage (non-représenté) de définir l'épaisseur d'encre déposée sur ledit cylindre. Le porte-lame 1 est monté sur des supports d'encrier 3 eux-mêmes montés sur un axe (non représenté) traversant l'ouverture de façon à permettre un basculement du porte-lame 1 de l'encrier. Dans ce mode d'exécution, les secteurs 2 ne se prolongent pas sur toute la largeur du porte-lame 1 et sont déplacés par déformation du porte-lame 1 d'une manière qui sera décrite plus loin dans la présente demande. L'encrier comporte également une butée de référence 5 réglable par des vis 6, des parois latérales de fermeture 7 et une bavette de protection 8. Les parois de fermeture sont connues dans l'état de la technique, par exemple de la publication EP 1 022 138 dont le contenu est incorporé par référence pour ce qui concerne ces parois latérales d'encrier. Le porte-lame 1 comporte également des trous 9 dont l'utilité sera expliquée plus loin dans la présente demande.In the first embodiment shown in FIG. the ink fountain comprises a blade holder 1 having sectors 2 which, by virtue of their position relative to the Inking cylinder (not shown) to define the thickness ink deposited on said cylinder. The blade holder 1 is mounted on inkwell supports 3 themselves mounted on a axis (not shown) passing through the opening so as to allow tilting of the blade holder 1 of the inkwell. In this mode of execution, sectors 2 do not extend across the entire width of the blade holder 1 and are moved by deformation of the blade holder 1 in a manner to be described later in this application. The inkwell features also a reference stop 5 adjustable by screws 6, closing side walls 7 and a flap of 8. The closing walls are known in the state of the art, for example EP 1 022 138 whose contents are incorporated by reference for this which concerns these side walls of inkwell. The blade holder 1 also has holes 9 whose utility will be explained later in this application.

L'encrier comporte en outre des systèmes de serrage 10 pour le maintien des parois latérales 7.The inkwell further comprises clamping systems 10 for maintaining the side walls 7.

Dans la figure 2, les éléments identiques à la figure 1 sont identifiés au moyen des même références numériques. Sur le porte-lame 1, on a fixé une lame d'encrier 11 et la butée de référence 5 est fermée par un cache 12, par exemple vissé par les vis 15.In FIG. 2, the elements identical to FIG. are identified by the same reference numbers. On the blade holder 1, an ink fountain blade 11 is attached and the reference stop 5 is closed by a cover 12, by example screwed by screws 15.

La lame d'encrier céramique 11 permet de régler l'épaisseur d'encre déposée tout en maintenant une arête continue, au contraire des secteurs individuels 2. En effet, l'on s'est aperçu que malgré des tolérances très précises entre les secteurs, de l'encre passait entre lesdits secteurs ce qui occasionne des coulures et des encrages imprécis. L'utilisation d'une lame telle que la lame 11 permet de garder une arête continue et, par conséquent, d'améliorer l'encrage. Le réglage de l'épaisseur de l'encre s'effectue manuellement par des vis 13 (il y en a une par segment) dont l'extrémité distale s'appuie directement en dessous de chaque segment 2. Ainsi, le vissage des vis 13 permet, par déformation du segment 2 respectif par rapport au porte-lame 1, de modifier la distance du bord supérieur dudit segment par rapport au cylindre d'encrage et, par conséquent l'arête de la lame céramique 11.The ceramic inkwell blade 11 makes it possible to adjust the thickness ink deposited while maintaining a continuous edge, at contrary to the individual sectors 2. Indeed, that despite very close tolerances between sectors, ink passed between these sectors which causes imprecise dripping and inking. The use of a blade such as the blade 11 makes it possible to keep a continuous edge and, therefore, improve inking. The adjustment of the ink thickness is carried out manually by screws 13 (there is one by segment) whose distal end leans directly below each segment 2. Thus, the screwing of the screws 13 allows, by deformation of the respective segment 2 with respect to the blade holder 1, to modify the distance of the upper edge of said segment relative to the inking cylinder and, by therefore the edge of the ceramic blade 11.

De préférence, pour améliorer le système, on dépose une matière plastique déformable entre les secteurs pour améliorer l'étanchéité entre ceux-ci.Preferably, to improve the system, a deformable plastic material between sectors for improve the seal between them.

La lame céramique 11 comprend des tirants à taraudages qui pénètrent dans les trous 9 du porte-lame 1 (voir figure 1) ce qui permet son rattachement au porte-lame 1 de façon fixe par vissage, les vis étant introduites par en dessous du porte-lame 1.The ceramic blade 11 comprises tapping rods which enter the holes 9 of the blade holder 1 (see Figure 1) which allows its attachment to the blade holder 1 so fixed by screwing, the screws being introduced from below of the blade holder 1.

Dans le deuxième mode d'exécution des figures 3 et 4, l'encrier est d'un type différent de celui du premier mode. Dans le premier mode, le réglage de l'épaisseur de l'encre s'effectuait de façon manuelle en agissant sur des vis 13 (voir figure 2) et en forçant le déplacement des secteurs 2. Dans le deuxième mode d'exécution, l'encrier est du type connu sous le nom "Colortronic MC" (commercialisé par la société Koenig & Bauer AG) dans lequel les secteurs qui définissent l'épaisseur de l'encre sont actionnés de façon automatique en rotation sur un axe. Ainsi, il n'y a pas de déformation de secteurs par rapport au porte-lame dans ce mode.In the second embodiment of FIGS. 3 and 4, the inkwell is of a different type from that of the first mode. In the first mode, adjusting the thickness of the ink was carried out manually by acting on screws 13 (see Figure 2) and forcing the displacement of the sectors 2. In the second embodiment, the inkwell is of the type known as "Colortronic ™" (marketed by the Koenig & Bauer AG) in which the sectors define the thickness of the ink are actuated so automatic rotation on an axis. So, there is no deformation of sectors with respect to the blade holder in this fashion.

Dans la figure 3, l'on a représenté un porte-lame 20 avec une butée de référence 25. Du côté du porte-lame 20 qui est proche du cylindre d'encrage (non représenté) se trouvent les secteurs 22 qui permettent de régler l'épaisseur de l'encrage. Comme indiqué ci-dessus, ce système fonctionne selon la machine connue sous le nom "Colortronic MC" dans laquelle les secteurs 22 sont montés sur un axe 23 et sont déplacés en rotation de façon automatique pour ajuster l'épaisseur de l'encre sur le cylindre d'encrage.In FIG. 3, there is shown a blade holder 20 with a reference stop 25. On the side of the blade holder 20 which is close to the inking cylinder (not shown) are sectors 22 that allow to adjust the thickness of inking. As stated above, this system works according to the machine known as "Colortronic MC" in which sectors 22 are mounted on an axis 23 and are moved in rotation automatically to adjust the thickness of the ink on the inking cylinder.

Par-dessus les secteurs 22, l'on a placé une lame 21 qui recouvre les secteurs 22 selon le principe de l'invention. Ainsi, c'est la tranche de cette lame 21 qui ajuste l'épaisseur de l'encre de façon continue le long de l'encrier, et non plus de secteurs 22 indépendants. Bien entendu, bien que non représenté dans les figures 3 et 4, ce mode d'exécution peut également comporter une bavette de protection 8 comme dans le premier mode d'exécution.Over sectors 22, a blade 21 has been placed which covers the sectors 22 according to the principle of the invention. So, this is the slice of this blade 21 that adjusts the thickness of the ink continuously along inkwell, and no longer independent sectors. Good understood, although not shown in Figures 3 and 4, this embodiment may also include a flap of protection 8 as in the first embodiment.

Dans la figure 4, l'on a représenté l'encrier avec le porte-lame 20 monté, dans la configuration d'utilisation. Dans cette configuration, la lame 21 est fixée au porte-lame 25 par une pièce de fixation 26 qui s'étend sur toute la largeur de l'encrier, cette pièce 26 étant attachée au porte-lame 25 par des vis 27 qui traversent la lame 21 par des trous 28 (figure 3) pour se visser dans des taraudages du porte-lame 25. In Figure 4, there is shown the inkwell with the blade holder 20 mounted in the configuration of use. In this configuration, the blade 21 is fixed to the blade holder 25 by a fastener 26 that extends over all the width of the inkwell, this piece 26 being attached to the blade holder 25 by screws 27 which pass through the blade 21 by holes 28 (Figure 3) to screw into threads of the blade holder 25.

La butée de référence 25 est attachée au porte-lame 20 par exemple par des vis ou par un autre moyen approprié.The reference stop 25 is attached to the blade holder 20 by example by screws or other suitable means.

La lame 11 ou 21 forme ainsi une pièce d'usure qui peut être facilement échangée et qui a un coût réduit. De préférence, la lame est en acier d'environ 1 à 3 mm et est recouverte par une couche de céramique de quelques microns d'épaisseur qui permet d'augmenter sensiblement sa durée de vie. En effet, les encres utilisées ont des propriétés abrasives qui usent l'arête de la lame de sorte que le dépôt de céramique permet de renforcer cette arête.The blade 11 or 21 thus forms a wear part which can to be easily exchanged and which has a reduced cost. Of preferably, the blade is made of steel of approximately 1 to 3 mm and is covered by a ceramic layer of a few microns of thickness which makes it possible to increase significantly its duration of life. Indeed, the inks used have properties abrasives that wear the edge of the blade so that the Ceramic deposition helps to strengthen this edge.

Bien entendu, les modes d'exécution décrits les sont à titre d'exemple et des variations sont possibles dans le cadre de la protection revendiquée. De mêmes, des moyens équivalents à ceux décrits sont possibles.Of course, the described embodiments are example and variations are possible in the framework of the claimed protection. Similarly, means equivalent to those described are possible.
