Definitions
- the present invention relates to a direct printing machine by projection of ink drops on a support.
- the inkjet technique is known (see eg. FR-A-2 707 919).
- piezoelectric ceramic print heads one chamber of which by deformation projects the ink at the outlet of the nozzles onto a support.
- the projection of the ink can also be obtained, for certain types of ink, by heating generating the formation of a gas bubble whose expulsion causes the ink jet.
- the relative displacements of the print head by ink jets and of the support to be printed are of small amplitude, which does not harm the quality of the print, the vacuum necessary at the output of the projection nozzles n not being affected by small displacements.
- These technologies are however only suitable for certain specific types of inks and are not suitable for the projection of inks with high corrosive power, the use of which is sought after for the quality of the impression obtained and for its unalterable adhesion on the support or for inks revealing by ultraviolet rays.
- the invention aims to produce a machine which can be used for direct printing, with corrosive inks, that is to say based on solvents or ultraviolet, on small or very large formats and on any type of support, especially rigid, flat or shaped.
- corrosive inks that is to say based on solvents or ultraviolet
- any type of support especially rigid, flat or shaped.
- Corrosive inks cannot be loaded into known dispensing cartridges of the HEWLETT PACKARD (registered trademark) or LEXMARK (registered trademark) type, it is necessary to design a specific ink supply system with devices making it possible to maintain a vacuum of 4 millibars at the level of the projection nozzles without pressure variation detrimental to a good impression, regardless of the technical data according to which the relative movements between the heads and projection nozzles must be very rapid.
- the heads and nozzles can be subjected to displacement speeds of 800 millimeters per second and to accelerations of 5000 millimeters per second squared, which generates a pressure variation at the level of the nozzles.
- the present invention aims to provide a solution to this problem in the production of a direct printing machine.
- each on-board buffer tank is divided to reduce the amplitude of the waves produced by the displacement of tanks.
- the machine comprises a rectangle table 1 comprising a flat, horizontal plate, of rectangle shape on which the support intended to receive the print is disposed.
- a transverse gantry 2 is movable in the X direction on the table.
- On the gantry 2 is mounted an on-board crew 3 mobile by any known means along the Y axis and the Z axis; the X, Y and Z axes being orthogonal in space.
- the mobile crew can therefore move in any direction on the table 1 and in height along Z relative to the latter. Its movements are controlled by a control and command unit comprising a microprocessor with associated equipment.
- the position of the moving assembly, particularly in height, with respect to the table, is adjusted by any known type of detection system
- the on-board crew 3 is shown in more detail in FIG. 2 with the system hydraulic.
- the high-speed mobile on-board crew includes one or more buffer tanks 6.
- four buffer tanks 6 are represented, each of them being dedicated to an ink color or to an ink tint used to compose a color, each of them is connected by a line of line 7 to the stationary tank 4, which includes as many chambers and lines as there are buffer tanks.
- One or two spray heads correspond to each buffer tank downstream piezoelectric or other system ink, each head feeding its projection nozzles carried by a nozzle plate.
- each buffer tank 6 supplies one projection head and only one.
- the buffer tanks 6 are independent of each other and are removably mounted on the moving element. This provision, by authorizing the individual replacement of each tank, facilitates the maintenance of the whole. In the same spirit, a similar provision will be made for projection heads and associated nozzles. Another advantage in the removability of tanks 6 and projection heads lies in the improvement of the flexibility of use of the machine printing.
- each reservoir 6 and associated projection head can now be assigned to a single color and a single ink category, this avoids the obligation of a complete cleaning of tanks and heads before replacing ink justified by chemical and / or physical incompatibility issues that may exist between inks of different categories and / or different colors.
- the mark 8 indicates the connections of each of the heads which are supplied by a servo solenoid valve 9 downstream of each of the buffer tanks 6.
- the distributors 9 are individually controlled by the control and command unit. By ordering solenoid valves is interrupted or communication between the buffer tanks and the associated projection heads and therefore the ink supply of the spray nozzles. These solenoid valves are controlled independently of each other other.
- a stationary solenoid valve 10 controlled by the stationary reservoir 4 the control and command unit. By controlling each of these solenoid valves is established or interrupted the communication between the associated tanks 4 and 6 and therefore whether or not the reservoir 6 is supplied with ink.
- tank 6 In order to detect the ink level in the tank and control the supply of ink when the level is at minimum and interrupt this supply when the level is at most, tank 6 is associated with a level detector capable of delivering two signals separate electrics, one of which is representative of a minimum level and the other of which is representative of a maximum level. This level detector is electrically connected to the unit of control and command to deliver to the latter the minimum level signals and maximum level.
- the buffer tanks 6 can be maintained in depression by a common line 11 with means of depression 12, said line being connected to a compressor 13.
- This means of depressurization is advantageously constituted by a venturi effect device.
- a venturi effect device Such a device, known per se, comprises a first channel internal provided at one of its ends with a compressed air inlet mouth and according to its other end of a compressed air outlet. In this internal channel radially the end of a second channel connected by its other end to line 11. By passage of an air flow in the first channel is created in the second a suction effect generator of depression.
- Line 11 is provided, between the compressor 13 and the venturi effect device 12, with control and adjustment means, such as filter, regulator and pressure gauge of known types and which are not described.
- control and adjustment means such as filter, regulator and pressure gauge of known types and which are not described.
- a branch 14 connected to line 11 is connected, by means of a controlled shutter 15, to a venturi effect device 16 which puts a reservoir 17 with vacuum valve 18 under vacuum.
- the vacuum tank 17 is connected by a solenoid valve 19 to the system 5 for cleaning and maintaining the ink spray nozzles.
- the venturi effect device 12 on line 11 maintains the buffer tank in depression.
- each buffer tank 6 is equipped with its own means of depression.
- This means of depression is made up advantageously by a venturi effect device 12 like that previously described.
- the suction mouth of this venturi effect device is connected directly by its mouth of suction through a through hole made in the upper wall of the buffer tank 6.
- a depression is created in the upper part of the tank 6, above the level ink.
- the buffer tanks are supplied with ink through lines 7, the ink supply pressure being of the order of 0.1 to 0.2 bar.
- each buffer tank 6 is supplied with ink by its own additional reservoir 34, the additional reservoir 34 being connected to the corresponding pipe 7 by the corresponding solenoid valve 10.
- This tank additional for example of cylindrical shape, comprises a bottom wall, an envelope wall standing vertically on the back wall and a shutter cover coming to rest on the shore horizontal top of the envelope wall to close the opening which delimits said wall at this level.
- the additional tank 34 receives the level detector device and is connected to the buffer tank 6 via a lower pipe 34a located below the minimum level ink and by an upper line 34b located above the ink level allowing respectively the ink supply to the buffer tank 6 and the balance of air pressures in both tanks.
- the pipes 34a and 34b provide a connection rigid mechanical between the buffer tank 6 and the additional tank 34.
- the lower part of the shell wall of the tank additional has a through hole to which the outlet outlet of the the solenoid valve 10.
- This additional tank is therefore supplied from below; we avoid thus during the ink supply, the formation of waves and shock waves, generating ink pressure variations in the additional tank 34 and in the buffer tank 6.
- the level detector is advantageously constituted by a float 35 and by a float position sensor 36, this sensor electrically connected to the control and control, being capable of delivering to said unit a minimum level signal and a signal maximum level.
- This detector is carried by the cover of the additional tank 34.
- the projection heads operate at slight depression. It is necessary for the regularity of impression that this depression remains constant around minus 4 millibars or undergo as few variations as possible, a variation of minus four to minus eight millibars being acceptable.
- each buffer tank 6 is divided to avoid the formation of waves.
- Figure 3 shows a sectional view of a buffer tank among the four on-board buffer tanks 6.
- Each buffer tank 6 is preferably a cylindrical volume, the top of which is closed and the base 20 of which towards the solenoid valve and the head is restricted. To this end, the bottom wall 21 of each buffer tank has a cylindrical volume of small height and of smaller diameter than that of the tank with an outlet nozzle 22. In the cylindrical volume of each of the buffer tanks 6 is introduced a dividing device 23 which breaks it down into several small tanks and fulfills a wave breaker damping function.
- the dividing device is a block of section corresponding to that of the internal volume of the buffer tank which is provided from top to bottom with parallel channels 24 defining as many small tanks.
- the divider has at its base a recess 25 facilitating the circulation of the ink. It goes without saying that any other system performing a division and partitioning of the tank can be adapted.
- Buffer tanks 6 and additional, dividers and covers are made of suitable materials, resistant to the solvents of the inks used.
- the device for cleaning the nozzle plates and for maintaining the nozzles connected to the compressor by the branch 14 (FIG. 2) and shown diagrammatically in position in FIG. 1 is shown in detail in FIGS. 6 and 7.
- It consists of a plate 26 of rectangular shape.
- On this plate are reservations of rectangular shape 27.
- In each of the reservations 27 open two channels 28 and 29 connected by pipes to the reservoir 17 in depression.
- the reservations 27 are aligned and offset at an angle relative to their alignment axis.
- the reservations 27 each receive a plate made of a flexible material, for example silicone.
- the plate has two oblong parallel oblique lights.
- a first short lumen 30 corresponds to a nozzle of the duct 28.
- the lumen 30 is provided with two lips 31 of low height.
- a second oblong opening 32 corresponds to the duct 29. This opening 32 has a scraping lip 33.
- the maintenance cycle for heads and nozzles is shown in Figure 8 in solid lines, the different stages of the cycle and the movement of the head or heads being identified by the letters A, B, C, D, E, F and G .
- A the projection head is brought to a speed V1 above the lips 31 of the light 30.
- B the head is lowered at a speed V2 onto the lips 31.
- C the depression at the head is interrupted; the suction is put into operation by action of the venturi effect device 16 for a time T1.
- D the head is raised by a value of 2 millimeters above the lips 31, the suction is stopped, the depression is restarted.
- E the head is moved at a speed V2 above the scraper lip 33.

Description
La projection de l'encre peut également être obtenue, pour certains types d'encre, par chauffage générant la formation d'une bulle gazeuse dont l'expulsion provoque le jet d'encre.
Ces technologies ne sont cependant adaptées qu'à certains types d'encres spécifiques et ne conviennent pas pour la projection d'encres à fort pouvoir corrosifs dont l'emploi est recherché pour la qualité de l'impression obtenue et pour son adhésion inaltérable sur le support ou pour les encres à révélation par rayons ultraviolets.
La réalisation d'une telle machine répondant à cette définition passe par la maítrise d'un certain nombre de problèmes.
A titre d'exemple, les têtes et buses peuvent être soumises à des vitesses de déplacement de 800 millimètres par seconde et à des accélérations de 5000 millimètres par seconde au carré, ce qui génère une variation de pression au niveau des buses.
Cela génère une dégradation de leur fonctionnement : arrêt de projection, jet dévié, etc...
La présente invention vise à apporter une solution à ce problème dans la réalisation d'une machine d'impression directe.
- la ou les têtes est ou sont portées par un équipage mobile au-dessus du support à imprimer suivant les trois axes X, Y et Z orthogonaux dans l'espace voir eg. EP-A-754 555 ;
- chacune des têtes est dotée d'un réservoir tampon porté par l'équipage mobile
- la ou les têtes et leur réservoir tampon sont maintenus en dépression et les réservoirs tampons sont alimentés en pression à partir d'un ou des réservoirs à poste fixe.
- la figure 1 est une vue schématique en plan d'une machine selon l'invention
- la figure 2 est une représentation schématique du système hydraulique de la machine selon l'invention
- la figure 3 est une vue schématique des réservoirs tampons avec têtes de projection
- les figures 4 et 5 sont des vues en plan et en coupe de l'insert diviseur introduit dans chacun des réservoirs.
- la figure 6 représente en plan le système de nettoyage et d'entretien des têtes et buses de projection qui est raccordé au circuit hydraulique
- la figure 7 est une vue en coupe du dispositif représenté à la figure 6
- la figure 8 représente schématiquement le cycle d'entretien
- la figure 9 représente en coupe un réservoir tampon et un réservoir additionnel.
Un portique 2 transversal est mobile dans le sens X sur la table.
Dans l'exemple de la figure 2 sont représentés quatre réservoirs tampons 6, chacun d'eux étant dédié à une couleur d'encre ou à une teinte d'encre servant à composer une couleur, chacun d'eux est relié par une ligne de conduite 7 au réservoir 4 à poste fixe, lequel comprend autant de chambres et de lignes qu'il y a de réservoirs tampons.
Le réservoir en dépression 17 est relié par un électrodistributeur 19 au système 5 de nettoyage et d'entretien des buses de projection d'encre.
Le dispositif à effet venturi 12 sur la ligne 11 maintient le réservoir tampon en dépression.
A cet effet, chaque réservoir tampon 6 est divisé pour éviter la formation de vagues.
La figure 3 représente vue en coupe un réservoir tampon parmi les quatre réservoirs tampons 6 embarqués.
A cet effet, la paroi du fond 21 de chaque réservoir tampon présente un volume cylindrique de faible hauteur et de plus petit diamètre que celui du réservoir avec un ajutage 22 de sortie.
Dans le volume cylindrique de chacun des réservoirs tampon 6 est introduit un dispositif diviseur 23 qui le décompose en plusieurs petits réservoirs et remplit une fonction d'amortisseur casseur de vagues.
Avantageusement, le diviseur présente à sa base un évidement 25 facilitant la circulation de l'encre.
Il va de soi que tout autre système réalisant une division et un cloisonnement du réservoir peut être adapté.
Il est constitué d'une platine 26 de forme rectangle.
Sur cette platine sont ménagées des réservations de forme rectangle 27. Dans chacune des réservations 27 débouchent deux canaux 28 et 29 raccordés par des conduites au réservoir 17 en dépression.
Les réservations 27 sont alignées et décalées en biais par rapport à leur axe d'alignement.
Les réservations 27 reçoivent chacune une plaquette en un matériau souple, par exemple en silicone.
La plaquette présente deux lumières oblongues parallèles en biais.
Une première lumière 30 courte correspond à un ajutage du conduit 28. La lumière 30 est dotée de deux lèvres 31 de faible hauteur.
Une deuxième lumière 32 oblongue correspond au conduit 29. Cette lumière 32 présente une lèvre de raclage 33.
En A la tête de projection est amenée à une vitesse V1 au-dessus des lèvres 31 de la lumière 30.
En B la tête est descendue à une vitesse V2 sur les lèvres 31.
En C la dépression à la tête est interrompue ; la succion est mise en fonctionnement par action du dispositif à effet venturi 16 pendant un temps T1.
En D la tête est remontée d'une valeur de 2 millimètres au-dessus des lèvres 31, la succion est arrêtée, la dépression est remise en marche.
En E la tête est déplacée à une vitesse V2 au-dessus de la lèvre racleuse 33.
En F la tête est remontée à une vitesse V3.
En G la tête est amenée au-dessus de la zone d'entretien et de la lumière 32, le crachage des trames, c'est-à-dire d'une quantité d'encre pendant un temps T, est déclenché.
Ce cycle d'entretien permet de nettoyer les buses et plaques à buse et d'amorcer les têtes et les buses tant en évitant un colmatage de celles ci, par exemple par évaporation des solvants.
