Abstract

The washer consists of a distributor (14) with jets (15-18), mounted between two side-pieces (9,10). The distributor is able to pivot in a stirrup (13) which can move laterally between the two side-pieces in a reciprocating motion along the inking components, with the angle of the distributor reversed at the end of each lateral movement. The reciprocating lateral movement of the distributor is produced by a linear pneumatic cylinder (21) between the two side-pieces. Its angular position is reversed at the end of each lateral movement by the jets interacting with a stop (31). <IMAGE>

Description

La présente invention concerne un dispositif de lavage des organes d'encrage d'une machine d'impression rotative, notamment pour le lavage du cylindre tramé de transfert d'encre, du bac à encre, de la chambre à racles et des diverses canalisations des organes d'encrage.The present invention relates to a device for washing the inking members of a rotary printing machine, in particular for washing the screened ink transfer cylinder, the ink tank, the doctor blade chamber and the various pipes of the inking bodies.

Actuellement, le lavage des organes d'impression des machines rotatives d'impression s'effectue, d'une manière bien connue des praticiens, en faisant circuler de l'eau dans les canalisations du circuit d'encrage et dans la chambre à racles par l'intermédiaire de la pompe à encre ou à l'aide de buses à l'intérieur de la chambre à râcles. Cette façon de faire nettoie tous les organes d'encrage ainsi que le cylindre tramé de transfert d'encre. Cependant, certains de ces organes d'encrage, en particulier la chambre à racles, reçoivent, sur leurs parties extérieures, des projections d'encre qui ne seront pas éliminées par ce mode de lavage. Il faudra alors les nettoyer indépendamment du lavage par circulation d'eau dans les canalisations du circuit d'encrage. Cette opération de nettoyage ne peut se faire que manuellement et prend un temps considérable en raison de la complexité des formes extérieures des organes d'encrage. Cet état de la technique provient de la pratique habituellement utilisée par les constructeurs de machines rotatives d'impression et apparaissant sur les catalogues ou prospectus propres à chacun de ces constructeurs.Currently, the washing of the printing members of the rotary printing machines is carried out, in a manner well known to practitioners, by circulating water in the pipes of the inking circuit and in the doctor blade chamber. through the ink pump or using nozzles inside the rake chamber. This procedure cleans all the inking elements as well as the screened ink transfer cylinder. However, some of these inking members, in particular the doctor blade chamber, receive, on their external parts, ink splashes which will not be eliminated by this washing mode. It will then be necessary to clean them independently of washing by circulation of water in the pipes of the inking circuit. This cleaning operation can only be done manually and takes considerable time due to the complexity of the external shapes of the inking members. This state of the art comes from the practice usually used by manufacturers of rotary printing machines and appearing in the catalogs or brochures specific to each of these manufacturers.

Le but de la présente invention consiste à proposer un dispositif de lavage qui simplifie les opérations de nettoyage en supprimant tout nettoyage manuel des organes d'impression de la machine rotative d'impression.The object of the present invention is to provide a washing device which simplifies the cleaning operations by eliminating any manual cleaning of the printing members of the rotary printing machine.

Ce but est atteint par un dispositif de lavage conforme à ce qu'énonce la revendication 1.This object is achieved by a washing device according to what is stated in claim 1.

L'invention est décrite ci-après de façon plus détaillée à l'aide d'un exemple d'exécution sans caractère limitatif et illustré par les dessins annexés dans lesquels :

  • La figure 1 est une vue en coupe partielle de la station d'encrage d'une machine rotative d'impression et,
  • La figure 2 est une vue selon A de la figure 1.
The invention is described below in more detail using an embodiment without limitation and illustrated by the accompanying drawings in which:
  • FIG. 1 is a partial section view of the inking station of a rotary printing machine and,
  • FIG. 2 is a view along A of FIG. 1.

La figure 1 est une vue en coupe partielle de la station d'encrage 1 d'une machine rotative d'impression flexographique comprenant un cylindre porte cliché 2 sur lequel l'encre est déposée au moyen d'un cylindre tramé de transfert d'encre 3 du type "Anilox". Une chambre à racles 4 est en contact avec le cylindre tramé de transfert d'encre 3 lorsque la machine est en phase d'impression. Dans cette figure, la chambre à racles 4, dans la phase d'impression, est représentée en traits mixtes en 4a. Dans la phase de lavage la chambre à racles 4 occupera la position représentée en 4b. Dans la phase d'impression, l'encre est amenée à la chambre à racles 4 par une conduite reliée à une pompe (non représentées) immergée dans un réservoir d'encre généralement placé à l'extérieur de la station d'encrage 1. La chambre à racles 4 est fixée sur un levier 6 pivotant autour d'un axe 7 sous l'action d'un cylindre pneumatique ou de tout autre actuateur autorisant ce pivotement entre les positions 4a et 4b. Le dispositif de lavage 8 est monté entre deux joues latérales 9 et 10 guidées dans des coulisses 11, 12. Le dispositif de lavage 8 comprend un étrier 13, entre les bras duquel est disposé un distributeur 14 équipé de quatre buses 15, 16, 17 et 18. Dans l'exécution choisie et pour des raisons d'efficacité de fonctionnement du dispositif de lavage 8, la buse centrale 16 à une longueur plus grande que les deux autres buses 15 et 17. Ce distributeur 14 est monté, de façon à pouvoir pivoter, entre les bras de l'étrier 13. La résistance au pivotement du distributeur 14 est obtenue par serrage de celui-ci entre les bras de l'étrier 13 en matière plastique. L'alimentation en fluide de nettoyage s'effectue par un raccord 19 placé à l'une des extrémités du distributeur 14, par une conduite 20. Le fluide de nettoyage peut être de l'eau sous pression prise du réseau et dont la pression est limitée dans une plage de deux à quatre bars. On peut aussi envisager d'utiliser un fluide de nettoyage pris d'un réservoir à l'aide d'une pompe. Dans ce cas, le fluide de nettoyage peut être un mélange d'eau et de détergent. L'étrier 13 est attaché à un cylindre pneumatique linéaire 21 fixé entre les deux joues latérales 9 et 10 sur une traverse 30. Le dispositif de lavage 8 peut être déplacé d'une position 22 à une position 23 sous l'effet d'un cylindre pneumatique 24 ancré dans les bâtis de la station d'encrage et dont la tige de piston 25 est reliée aux joues latérales 9 et 10. Les buses 15, 16 et 17 sont dirigées vers le bas en direction de la chambre à racles 4 lorsque celle-ci occupe la position 4b alors que la buse 18, placée à l'extrémité opposée à l'alimentation en fluide de lavage, est dirigée en direction du cylindre tramé de transfert d'encre. Le dispositif de lavage 8 est guidé, lors de son déplacement de la position 22 à la position 23, par les galets 26 et 27 s'engageant dans les coulisses 11 et 12. Lors de la phase de lavage, le fluide de nettoyage est recueilli par un bac de récupération 5 puis évacué par un tuyau 28 vers une installation d'épuration avant d'être mis à l'égout. Le dispositif de lavage 8 est fermé, sur sa partie opposée à la chambre à racles en position 4a, par une tôle de protection 29 fixée aux deux joues latérales 9 et 10.Figure 1 is a partial sectional view of the inking station 1 of a rotary flexographic printing machine comprising a plate cylinder 2 on which the ink is deposited by means of a screened ink transfer cylinder 3 of the "Anilox" type. A doctor blade chamber 4 is in contact with the screened ink transfer cylinder 3 when the machine is in the printing phase. In this figure, the doctor blade chamber 4, in the printing phase, is shown in phantom in 4a. In the washing phase, the doctor blade chamber 4 will occupy the position shown in 4b. In the printing phase, the ink is brought to the doctor blade chamber 4 by a line connected to a pump (not shown) immersed in an ink tank generally placed outside the inking station 1. The doctor blade chamber 4 is fixed to a lever 6 pivoting about an axis 7 under the action of a pneumatic cylinder or any other actuator allowing this pivoting between positions 4a and 4b. The washing device 8 is mounted between two lateral cheeks 9 and 10 guided in slides 11, 12. The washing device 8 comprises a stirrup 13, between the arms of which is arranged a dispenser 14 equipped with four nozzles 15, 16, 17 and 18. In the chosen embodiment and for reasons of operating efficiency of the washing device 8, the central nozzle 16 to a greater length than the other two nozzles 15 and 17. This distributor 14 is mounted, so as to be able to pivot, between the arms of the stirrup 13. The resistance to pivoting of the distributor 14 is obtained by clamping it between the arms of the stirrup 13 made of plastic. The cleaning fluid is supplied by a connector 19 placed at one end of the distributor 14, by a pipe 20. The cleaning fluid can be pressurized water taken from the network and whose pressure is limited in a range of two to four bars. One can also consider using a cleaning fluid taken from a tank using a pump. In this case, the cleaning fluid can be a mixture of water and detergent. The stirrup 13 is attached to a linear pneumatic cylinder 21 fixed between the two lateral cheeks 9 and 10 on a cross-member 30. The washing device 8 can be moved from a position 22 to a position 23 under the effect of a pneumatic cylinder 24 anchored in the frames of the inking station and the piston rod 25 of which is connected to the lateral cheeks 9 and 10. The nozzles 15, 16 and 17 are directed downwards towards the doctor blade chamber 4 when this occupies position 4b while the nozzle 18, placed at the end opposite to the supply of washing fluid, is directed towards the screened ink transfer cylinder. The washing device 8 is guided, when it moves from position 22 to position 23, by the rollers 26 and 27 engaging in slides 11 and 12. During the washing phase, the cleaning fluid is collected by a recovery tank 5 and then evacuated by a pipe 28 to a purification installation before being put in the sewer. The washing device 8 is closed, on its part opposite the doctor blade chamber in position 4a, by a protective plate 29 fixed to the two lateral cheeks 9 and 10.

La figure 2 est une vue selon A de la figure 1 dans laquelle on voit la disposition des divers éléments composant le dispositif de lavage 8. Sur cette figure, seule la moitié gauche du dispositif de lavage 8 a été représentée, son autre moitié étant parfaitement symétrique par rapport à l'axe X. Au voisinage de chacune des extrémités du cylindre pneumatique linéaire 21, on a monté une butée cylindrique 31 fixée sur un socle 32 vissé contre la traverse 30.Figure 2 is a view along A of Figure 1 in which we see the arrangement of the various elements making up the washing device 8. In this figure, only the left half of the washing device 8 has been shown, its other half being perfectly symmetrical with respect to the axis X. In the vicinity of each of the ends of the linear pneumatic cylinder 21, a cylindrical stop 31 has been mounted, fixed on a base 32 screwed against the cross-member 30.

L'opération de nettoyage des organes d'encrage s'effectue de la manière suivante : On procède premièrement au rinçage du circuit d'encrage, c'est à dire du circuit amenant l'encre à la chambre à racle 4, d'une façon tout à fait conventionnelle en injectant un fluide de nettoyage dans la pompe à encre. Ce fluide de nettoyage va rincer l'intérieur de la chambre à racles 4 en position 4a et également nettoyer le cylindre tramé de transfert d'encre 3. Ensuite, on interrompra l'arrivée du fluide de nettoyage dans le circuit d'encrage, on actionnera les cylindres pneumatiques 24 de façon à ce que le dispositif de lavage 8 passe de la position 22 à la position 23, on fera pivoter la chambre à racles 4 de la position 4a à la position 4b puis l'on actionnera à nouveau les cylindres pneumatiques 24 de manière à ce que le dispositif de lavage 8 vienne à nouveau occuper la position 22. A cet instant, le fluide de nettoyage sera injecté dans le distributeur 14 et le cylindre pneumatique linéaire 21 sera actionné de façon à ce que l'étrier 13 portant le distributeur 14 soit déplacé dans un mouvement de va et vient sur toute la longueur de la chambre à racle 4. Ainsi, chaque fois que les buses 15, 16 et 17 arriveront en contact avec les butées cylindriques 31 leur orientation, par rapport à la chambre à racles 4, sera modifiée. Le fluide de nettoyage sera de ce fait projeté sur l'intérieur et sur toute la surface de la chambre à racles 4 suivant deux angles différents ce qui assurera un nettoyage parfait de toutes les surfaces de la chambre à racles 4 ayant été souillées par des projections d'encre. De plus, lors du mouvement de va et vient du dispositif de lavage 8, la buse 18 giclera du fluide de nettoyage sur le cylindre tramé de transfert d'encre 3 qui, dans cette phase de nettoyage, sera entraîné en rotation. L'opération de nettoyage ayant pris fin, on pourra ensuite introduire de l'air comprimé dans les conduites d'alimentation du dispositif de lavage 8, ce qui aura pour effet de sécher les organes d'encrage et par la même occasion débarrassera les buses 15 à 18 de tout résidu de fluide de nettoyage et de ce fait évitera leur entartrage. Le séchage des organes d'encrage étant achevé, le dispositif de lavage sera relevé dans la position 23, la chambre à racles 4 sera ramenée dans sa position 4a correspondant à une nouvelle phase d'impression et ensuite, le dispositif de lavage 8 reprendra la position 22. Pour parfaire le nettoyage, on pourra encore réintroduire du fluide de nettoyage dans le circuit du dispositif de lavage 8 et le remettre en action pour finir le nettoyage du bac de récupération 5. Une nouvelle et dernière période de soufflage d'air comprimé interviendra et de l'encre d'une couleur différente pourra être introduite dans le circuit des organes d'encrage sans que l'on encourre le risque de voir cette encre souillée par des résidus provenant de l'encre, d'une autre couleur, précédemment utilisée dans la station d'impression. L'emploi de buses présente en outre l'avantage de pouvoir doser la quantité de fluide de nettoyage en réalisant ainsi une économie substantielle de ce fluide de nettoyage ce qui constituera un apport écologique appréciable lors de l'utilisation du dispositif de lavage qui vient d'être décrit.The cleaning operation of the inking members is carried out as follows: Firstly, the inking circuit is rinsed, that is to say the circuit bringing the ink to the doctor blade chamber 4, with a completely conventional way by injecting a cleaning fluid into the ink pump. This cleaning fluid will rinse the inside of the doctor blade chamber 4 in position 4a and also clean the screened ink transfer cylinder 3. Then, we will interrupt the arrival of the cleaning fluid in the inking circuit, we actuate the pneumatic cylinders 24 so that the washing device 8 passes from position 22 to position 23, the doctor blade chamber 4 will be pivoted from position 4a to position 4b and then the cylinders will be actuated again tires 24 so that the washing device 8 again occupies position 22. At this instant, the cleaning fluid will be injected into the distributor 14 and the linear pneumatic cylinder 21 will be actuated so that the stirrup 13 carrying the distributor 14 is moved in a back and forth movement over all the length of the doctor blade chamber 4. Thus, each time that the nozzles 15, 16 and 17 come into contact with the cylindrical stops 31 their orientation, relative to the doctor blade chamber 4, will be changed. The cleaning fluid will therefore be sprayed onto the interior and over the entire surface of the doctor chamber 4 at two different angles, which will ensure perfect cleaning of all surfaces of the doctor chamber 4 that have been soiled by projections. ink. In addition, during the back and forth movement of the washing device 8, the nozzle 18 will spray cleaning fluid onto the screened ink transfer cylinder 3 which, in this cleaning phase, will be driven in rotation. The cleaning operation having ended, we can then introduce compressed air into the supply lines of the washing device 8, which will have the effect of drying the inking members and at the same time clear the nozzles 15 to 18 of any cleaning fluid residue and therefore will prevent scaling. The drying of the inking members having been completed, the washing device will be raised to position 23, the doctor blade chamber 4 will be brought back to its position 4a corresponding to a new printing phase and then, the washing device 8 will resume position 22. To complete the cleaning, it is also possible to reintroduce cleaning fluid into the circuit of the washing device 8 and to put it back into action to finish cleaning the recovery tank 5. A new and final period of blowing of compressed air will occur and ink of a different color may be introduced into the circuit of the inking members without the risk of seeing this ink contaminated by residues from the ink, d another color, previously used in the printing station. The use of nozzles also has the advantage of being able to dose the quantity of cleaning fluid, thereby achieving a substantial saving in this cleaning fluid, which will constitute an appreciable ecological contribution when using the washing device which has just been used.
