Description

La présente invention concerne le marquage de produits au défilé, par jets d'encre. Plus particulièrement, l'invention concerne un procédé et un dispositif pour le marquage au défilé par jets d'encre d'une surface non parallèle au plan de défilement des produits, notamment d'une surface cylindrique telle que le roule des bobines de papier.The present invention relates to the marking of products on parade, by ink jets. More particularly, the invention relates to a method and a device for marking in the parade by ink jets of a surface not parallel to the plane of travel of the products, in particular of a cylindrical surface such as the rolls of paper reels.

Le marquage par jets d'encre consiste à projeter de l'encre selon des séquences données à partir de plusieurs buses alignées pour former des points d'encre qui définissent des caractères d'impression.Ink jet marking consists of spraying ink in given sequences from several aligned nozzles to form ink dots which define printing characters.

Le marquage des bobines de papier par jets d'encre est connu. Il s'effectue sur la tranche des bobines, en ligne droite, en faisant défiler la bobine devant le dispositif de marquage, ou encore en déplaçant celui-ci devant elle, le plan de défilement étant toujours parallèle à la surface à marquer. Le marquage peut aussi s'effectuer sur la partie cylindrique ou roule de la bobine. Il s'effectue alors toujours à un poste où la bobine, immobile en translation, peut être animée d'un mouvement de rotation sur elle-même. Il exige alors des moyens importants pour faire tourner la bobine sur elle-même, et aussi une durée d'immobilisation en translation de la bobine au moins égale à la durée du marquage.Marking of paper reels with ink jets is known. It is carried out on the edge of the reels, in a straight line, by scrolling the reel in front of the marking device, or by moving it in front of it, the running plane being always parallel to the surface to be marked. The marking can also be carried out on the cylindrical or rolled part of the reel. It is then always carried out at a station where the coil, stationary in translation, can be driven in a rotational movement on itself. It then requires significant means to rotate the coil on itself, and also a period of immobilization in translation of the coil at least equal to the duration of the marking.

L'invention propose un procédé et un dispositif pour le marquage au défilé de produits par jets d'encre sur au moins une surface desdits produits, surface disposée non parallèlement au plan de défilement de ceux-ci, procédé et dispositif particulièrement simples, faciles à mettre en oeuvre et qui ne demandent aucune immobilisation des produits à marquer. L'invention s'applique au marquage de nombreux produits de formes différentes, présentant des surfaces à marquer planes ou curvilignes, par exemple des produits de formes triangulaire, curviligne, cylindrique, etc...The invention provides a method and a device for marking products in parade by ink jets on at least one surface of said products, surface arranged not parallel to the plane of travel thereof, particularly simple method and device, easy to to implement and which do not require any immobilization of the products to be marked. The invention applies to the marking of many products of different shapes, having planar or curvilinear surfaces to be marked, for example products of triangular, curved shapes. line, cylindrical, etc ...

Conformément à l'invention, on déplace de façon rectiligne le produit à marquer, en face d'au moins une tête de marquage, la ou les surfaces à marquer étant disposées non parallèlement au plan de défilement du produit, et on marque la ou les surfaces au défilé, en maintenant élastiquement la ou les têtes de marquage perpendiculairement à la ou les surfaces à marquer, à une distance constante de celles-ci, durant toute l'opération de marquage.According to the invention, the product to be marked is moved in a rectilinear fashion, opposite at least one marking head, the surface or surfaces to be marked being arranged not parallel to the running plane of the product, and the product (s) is marked running surfaces, resiliently holding the marking head or heads perpendicular to the surface or surfaces to be marked, at a constant distance therefrom, throughout the marking operation.

Bien que l'invention s'applique au marquage de produits divers, par soucis de simplification, la description suivante se référera essentiellement au marquage du roule des bobines de papier.Although the invention applies to the marking of various products, for the sake of simplification, the following description will essentially refer to the marking of the rolls of the paper reels.

Selon l'invention, la bobine peut être disposée sur le convoyeur rectiligne, couchée sur le roule, son axe étant perpendiculaire au plan du convoyeur. Dans ce cas la tête de marquage est disposée au dessus du convoyeur et le marquage au défilé est effectué par le dessus du roule. Mais généralement, la bobine est disposée debout sur la tranche, là ou les têtes de marquage étant alors disposées sur le côté du convoyeur et le marquage au défilé étant effectué par le côté. On peut ainsi, avantageusement, marquer successivement ou simultanément deux côtés opposés du roule (ou deux faces latérales d'un produit de forme triangulaire par exemple).According to the invention, the reel can be placed on the straight conveyor, lying on the roll, its axis being perpendicular to the plane of the conveyor. In this case the marking head is arranged above the conveyor and the marking at the parade is carried out from above the roll. But generally, the reel is placed upright on the edge, there or the marking heads then being arranged on the side of the conveyor and the marking in the parade being carried out from the side. It is thus advantageously possible to successively or simultaneously mark two opposite sides of the roll (or two lateral faces of a product of triangular shape for example).

De préférence, on marque ainsi une partie du roule qui s'étend de part et d'autre du plan axial de basculement c'est-à-dire du plan axial perpendiculaire au déplacement de la bobine lorsque celle-ci est disposée sur la tranche. De préférence, l'inscription est sensiblement symétrique par rapport à ce plan axial de basculement.Preferably, this marks a part of the roll which extends on either side of the axial tilting plane, that is to say of the axial plane perpendicular to the displacement of the coil when the latter is disposed on the edge . Preferably, the inscription is substantially symmetrical with respect to this axial tilting plane.

L'invention concerne encore un dispositif pour le marquage au défilé de produits, marquage par jets d'encre sur au moins une surface desdits produits, disposée non parallèlement au plan de défilement de ceux-ci. Le dispositif, selon l'invention, comprend un convoyeur rectiligne pour les produits à marquer, au moins une tête de marquage disposée au dessus du convoyeur ou sur le côté, cette tête étant articulée autour d'un axe parallèle au plan de défilement des produits, au bout d'un système à débattement et rappel élastiques, agissant essentiellement perpendiculairement à l'axe du convoyeur tel un ressort ou un vérin, qui assure le maintien de la tête en position de marquage durant toute l'opération, un système de guidage déterminant l'orientation correcte à tout instant de la tête de marquage.The invention also relates to a device for marking products in a parade, marking by ink jets on at least one surface of said products, arranged not parallel to the plane of travel thereof. The device according to the invention comprises a rectilinear conveyor for the products to be marked, at least one marking head disposed above the conveyor or on the side, this head being articulated around an axis parallel to the plane of travel of the products , at the end of a system with elastic movement and return, acting essentially perpendicular to the axis of the conveyor such as a spring or a jack, which ensures the maintenance of the head in the marking position during the whole operation, a guidance system determining the correct orientation of the marking head at all times.

Dans une réalisation du dispositif, le système de guidage est un palpeur qui entoure la tête de marquage et qui comprend des tipes terminées par des billes de roulement servant de points de touche sur la surface à marquer, notamment le roule de la bobine pour suivre celui-ci sans pour autant frotter et éventuellement détériorer la bobine.In one embodiment of the device, the guidance system is a feeler which surrounds the marking head and which includes tipes terminated by rolling balls serving as touch points on the surface to be marked, in particular the roll of the spool to follow it without rubbing and possibly damaging the spool .

Dans une réalisation du dispositif, lorsque la bobine est disposée sur la tranche, deux têtes de marquage peuvent être associées, chacune d'elles opérant simultanément ou séparément sur des côtés opposés du roule par rapport au plan axial de la bobine, parallèle au déplacement de celle-ci.In one embodiment of the device, when the reel is placed on the edge, two marking heads can be associated, each of them operating simultaneously or separately on opposite sides of the roll relative to the axial plane of the reel, parallel to the movement of this one.

De préférence, le dispositif comprend un système donnant à la tête de marquage une orientation vers l'amont, c'est-à-dire vers le centre de la bobine, à l'approche de cette dernière. C'est par exemple un système pneumatique à course réglable.Preferably, the device comprises a system giving the marking head an upstream orientation, that is to say towards the center of the reel, when approaching the latter. It is for example a pneumatic system with adjustable stroke.

D'autres avantages et caractéristiques de l'invention apparaitront dans la description suivante d'exemples de réalisation du dispositif.

  • Les figures 1 et 2 représentent schématiquement le principe de marquage selon l'invention.
  • La figure 3 représente en vue de plan une réalisation du dispositif de marquage.
Other advantages and characteristics of the invention will appear in the following description of exemplary embodiments of the device.
  • Figures 1 and 2 schematically represent the marking principle according to the invention.
  • Figure 3 shows in plan view an embodiment of the marking device.

Sur la figure 1, une bobine de papier debout sur la tranche (ou couché sur le roule) est entraînée par un convoyeur rectiligne non représenté dans un mouvement d'avance selon la flèche F. La tête de marquage 2 est représentée dans trois positions successives de marquage.In FIG. 1, a reel of paper standing on the edge (or lying on the roll) is driven by a rectilinear conveyor not shown in a forward movement according to arrow F. The marking head 2 is represented in three successive positions marking.

La position A correspond au début du marquage. La tête de marquage, articulée autour d'un axe 3 parallèle à celui de la bobine, c'est-à-dire parallèle au plan de défilement de celle-ci (le plan de défilement passant par l'axe de la bobine), est orientée vers le centre de celle-ci, vers l'amont, par un palpeur à billes 4 qui épouse la courbure de la bobine, et qui est solidaire de la tête. L'axe 3 est monté au bout d'un système à débattement et rappel élastiques 5 agissant perpendiculairement à l'axe du convoyeur. Ce système maintient le palpeur appliqué contre le roule 6 de la bobine et donc la tête à proximité de celui-ci, grâce à la composante radiale R de la force qu'il exerce sur l'axe 3. Ainsi, les buses 7 par lesquelles l'encre pour l'impression est projetée sont disposées à une distance convenable et constante de la bobine. Au cours du déplacement de la bobine, celle-ci écarte le palpeur et la tête de marquage de l'axe du convoyeur et le système à débattement et rappel élastiques se rétracte perpendiculairement selon la flèche F1.Position A corresponds to the start of the marking. The marking head, articulated around an axis 3 parallel to that of the coil, that is to say parallel to the plane of travel of the latter (the plane of travel passing through the axis of the coil), is oriented towards the center thereof, upstream, by a ball feeler 4 which follows the curvature of the coil, and which is integral with the head. The axis 3 is mounted at the end of a system with elastic travel and return 5 acting perpendicular to the axis of the conveyor. This system keeps the probe applied against the roll 6 of the coil and therefore the head close to the latter, thanks to the radial component R of the force which it exerts on the axis 3. Thus, the nozzles 7 by which the ink for printing is projected are arranged at a suitable and constant distance from the spool. During the displacement of the reel, this moves the probe and the marking head away from the axis of the conveyor and the system with elastic travel and return retracts perpendicularly according to arrow F 1 .

La position B correspond généralement à la position médiane pour le marquage. Dans cette position, la tête est située dans le plan de basculement b. Le système élastique est rétracté au maximum.Position B generally corresponds to the middle position for marking. In this position, the head is located in the tilting plane b. The elastic system is retracted to the maximum.

La position C correspond à la fin du marquage. La tête est toujours orientée vers le centre de la bobine par le palpeur, mais vers l'aval cette fois. Le système élastique est dans sa course de sortie selon F2.Position C corresponds to the end of the marking. The head is still oriented towards the center of the coil by the probe, but downstream this time. The elastic system is in its exit stroke according to F 2 .

La figure 2 représente une variante de mise en oeuvre de l'invention, mais qui applique le même principe de marquage. Dans cette variante, l'axe 8 autour duquel est articulée la tête de marquage9, est monté au bout d'un bras oscillant 10, selon les flèches F3 et F4 autour d'un axe 11 parallèle à celui de la bobine. Le bras oscillant 10 est disposé sensiblement selon une parallèle à l'axe du convoyeur lorsque la bobine est disposée sur la tranche. Cette variante fait appel aux mêmes moyens d'orientation de la tête, c'est-à-dire un palpeur à billes 12 maintenu appliqué contre le roule de la bobine.FIG. 2 represents a variant implementation of the invention, but which applies the same principle of marking. In this variant, the axis 8 around which the marking head 9 is articulated, is mounted at the end of an oscillating arm 10, according to the arrows F 3 and F 4 around an axis 11 parallel to that of the coil. The oscillating arm 10 is disposed substantially along a parallel to the axis of the conveyor when the coil is arranged on the wafer. This variant uses the same means for orienting the head, that is to say a ball probe 12 kept applied against the roll of the reel.

La figure 3 représente en position de marquage une réalisation du dispositif selon l'invention pour la mise en oeuvre du marquage au défilé, la bobine de papier 1 étant disposée debout sur la tranche, sur un convoyeur rectiligne. La tête de marquage 20 est montée dans une structure 21 portée par un étrier 22 pivotant autour d'un axe vertical 23 porté par une bride 24. La tête de marquage est disposée dans un plan perpendiculaire à l'axe de la bobine.Figure 3 shows in the marking position an embodiment of the device according to the invention for the implementation of the marking in the parade, the paper reel 1 being disposed standing on the edge, on a straight conveyor. The marking head 20 is mounted in a structure 21 carried by a stirrup 22 pivoting about a vertical axis 23 carried by a flange 24. The marking head is arranged in a plane perpendicular to the axis of the coil.

La structure 21 comprend une plaque métallique 25 sur laquelle sont fixées quatre tiges 26 disposées autour de la tête de marquage à ses quatre coins. Chacune de ces tiges porte à son bout une bille de manutention 27 dont la position est réglable à l'aide d'un système vis-écrou 28. La position des billes est réglée de sorte que le contact de ces billes avec le roule 6 de la bobine correspond à une distance déterminée des buses de marquage 29 avec ce roule.The structure 21 comprises a metal plate 25 on which are fixed four rods 26 arranged around the marking head at its four corners. Each of these rods carries at its end a handling ball 27, the position of which is adjustable using a screw-nut system 28. The position of the balls is adjusted so that the contact of these balls with the roller 6 of the coil corresponds to a determined distance from the marking nozzles 29 with this roll.

La bride 24 est montée sur une plaque 30 porteuse d'un second étrier 31 traversé par un axe horizontal 32 sur lequèl est articulée la tige 33 d'un ressort pneumatique 34 dont le corps est monté dans une tige creuse 35 et sur un axe 36 traversant cette tige. La liaison de la tige 33 avec la plaque 30 peut se faire par une simple attache. La tige 35 est réglable selon la double flèche Y transversalement par rapport au déplacement de la bobine , en étant monté coulissante dans deux pa- llers horizontaux 37 portés par une plaque 38 montée en bout d'une autre tige solidaire d'un bâti non représenté.The flange 24 is mounted on a plate 30 carrying a second bracket 31 crossed by a horizontal axis 32 on which is articulated the rod 33 of a pneumatic spring 34 whose body is mounted in a hollow rod 35 and on an axis 36 crossing this rod. The connection of the rod 33 with the plate 30 can be done by a simple fastener. The rod 35 is adjustable according to the double arrow Y transversely with respect to the displacement of the coil, by being slidably mounted in two sides. horizontal llers 37 carried by a plate 38 mounted at the end of another rod secured to a frame not shown.

D'autres combinaisons utilisant au moins trois tiges sont bien entendu envisageables pour constituer un palpeur qui outre la fonction d'orientation de la tête peut remplir également une fonction de protection des buses.Other combinations using at least three rods can of course be envisaged to constitute a feeler which, in addition to the function of orienting the head, can also fulfill a function of protecting the nozzles.

La tige coulissante 35 porte à son extrémité 40 deux paliers horizontaux 41 disposés transversalement par rapport au déplacement de la bobine, dans lesquels coulissent deux tiges-guide 42 dont les extrémités 43 sont fixées sur la plaque 30. L'avance des tiges guides est limitée par deux butées 44. Les deux tiges-guide 42 encadrent la tige 33 du ressort pneumatique 34. La longueur de ces tiges et la course de la tige du ressort pneumatique se déterminent aisément en fonction de la longueur désirée pour le marquage et du diamètre des bobines.The sliding rod 35 carries at its end 40 two horizontal bearings 41 arranged transversely to the displacement of the coil, in which slide two guide rods 42 whose ends 43 are fixed on the plate 30. The advance of the guide rods is limited by two stops 44. The two guide rods 42 frame the rod 33 of the air spring 34. The length of these rods and the stroke of the air spring rod are easily determined according to the length desired for the marking and the diameter of the coils.

La plaque 30 porte encore un capot 45 entourant le corps d'un ressort pneumatique 46 monté sur un axe 47 traversant ledit capot 45. La tige 48 de ce ressort est fixée à un autre axe 49 porté par un palier 50, monté sur la partie aval de la plaque 25 de la structure 21, de sorte que la tête de marquage est orientée vers la bobine au moment de son approche. A l'extrémité aval 51 de la plaque 25, une cinquième tige réglable 52 porte une bille de manutention 53 réglable à l'aide d'un système vis-écrou 54, cette bille étant appliquée sur le roule de la bobine par l'action du ressort pneumatique 46. Les quatre tiges 26 et la tige 52, équipées de billes constituent un dispositif de guidage à palpeur qui donne l'orientation correcte à tout instant à la tête de marquage.The plate 30 also carries a cover 45 surrounding the body of an air spring 46 mounted on an axis 47 passing through said cover 45. The rod 48 of this spring is fixed to another axis 49 carried by a bearing 50, mounted on the part downstream of the plate 25 of the structure 21, so that the marking head is oriented towards the coil when it approaches it. At the downstream end 51 of the plate 25, a fifth adjustable rod 52 carries a handling ball 53 adjustable using a screw-nut system 54, this ball being applied to the roll of the coil by the action of the pneumatic spring 46. The four rods 26 and the rod 52, fitted with balls, constitute a sensor guide device which gives the correct orientation to the marking head at all times.

Le dispositif fonctionne de la manière suivante :

  • On détermine la position de la tête de marquage par rapport au convoyeur et aux bobines à marquer par réglage de la tige 35 qui est ensuite bloquée, par exemple à l'aide de vis. Sous l'action des deux ressorts pneumatiques qui sont en fin de course, la tête de marquage est orientée selon un angle d'attaque déterminé pour l'approche rectiligne de la bobine qui est disposée debout sur la tranche sur le convoyeur. La longueur des tiges 26 et 52 sont également réglées. La bobine arrivant au poste de marquage, la bille 53 vient en premier au contact du roule 6, la tête de marquage pivote autour de l'axe 23 jusqu'à ce que les billes 27 arrivent au contact du roule. La tête est alors correctement-orientée, selon un rayon de la bobine.
The device works as follows:
  • The position of the marking head relative to the conveyor and to the coils to be marked is determined by adjusting the rod 35 which is then locked, for example using screws. Under the action of the two pneumatic springs which are at the end of the stroke, the marking head is oriented according to a determined angle of attack for the rectilinear approach of the coil which is placed upright on the edge on the conveyor. The length of the rods 26 and 52 are also adjusted. The reel arriving at the marking station, the ball 53 comes first into contact with the wheel 6, the marking head pivots about the axis 23 until the balls 27 come into contact with the wheel. The head is then correctly oriented, according to a radius of the coil.

L'opération de marquage proprement dite commence. Le marquage par jets d'encre est programmé de façon connue à l'aide d'un microprocesseur. Les différentes buses sont alimentées en encre, par des tuyaux d'alimentation non représentés, de façon séquencée. Le marquage s'effectue sur le roule de la bobine au défilé, lors du passage de celle-ci devant la tête de marquage qui épouse à tout moment la courbure de la bobine grâce aux billes de manutention appliquées contre le roule par les ressorts pneumatiques. Au fur et à mesure de l'avance de la bobine, sous la poussée de celle-ci, la tête de marquage s'éloigne de plus en plus de l'axe du convoyeur. Les tiges de guidage 42 coulissent à l'intérieur des deux paliers 41 et les tiges des deux ressorts pneumatiques se rétractent. Lorsque les buses 29 de la tête de marquage franchissent le plan de basculement b, la tête de marquage en changeant d'inclinaison, poursuit son tracé le long du roule de la bobine sous l'action des ressorts pneumatiques et du palpeur.The actual marking operation begins. Marking by ink jets is programmed in a known manner using a microprocessor. The different nozzles are supplied with ink, by supply pipes, not shown, in a sequenced manner. The marking is carried out on the roll of the reel during the parade, during the passage of the latter in front of the marking head which marries at all times the curvature of the reel thanks to the handling balls applied against the roll by the pneumatic springs. As the reel advances, under the push of the reel, the marking head moves further and further away from the axis of the conveyor. The guide rods 42 slide inside the two bearings 41 and the rods of the two air springs retract. When the nozzles 29 of the marking head cross the tilting plane b, the marking head, by changing the inclination, continues its course along the roll of the coil under the action of the pneumatic springs and the feeler.

Après la fin'du marquage, la bobine s'échappe du dispositif de marquage et la tête reprend son inclinaison d'origine, c'est-à-dire une orientation vers l'amont et elle est alors prête pour le marquage de la bobine suivante.After the end of the marking, the reel escapes from the marking device and the head returns to its original inclination, that is to say an orientation upstream and it is then ready for the marking of the reel next.
