Description

La présente invention concerne une machine de sérigraphie comportant un cadre d'impression ou écran fixe par rapport au bàti de la machine, tout au moins pendant l'impression, un plateau d'impression monté pivotant par rapport à ce bâti de manière à s'ouvrir vers le bas, et un dispositif de raclage et de nappage.The present invention relates to a screen printing machine comprising a printing frame or screen fixed relative to the frame of the machine, at least during printing, a printing plate mounted to pivot relative to this frame so as to open down, and a scraper and topping device.

Elle a pour objet une machine de ce genre perfectionnée de manière notamment à faciliter son utilisation.It relates to a machine of this kind improved in particular so as to facilitate its use.

La machine selon l'invention est caractérisée en ce que le cadre d'impression et le plateau d'impression sont montés en porte-à-faux par rapport au bàti, l'axe de pivotement du plateau étant disposé à l'arrière du bâti.The machine according to the invention is characterized in that the printing frame and the printing plate are mounted in cantilever with respect to the frame, the pivot axis of the plate being disposed at the rear of the frame .

Gràce à cette disposition, trois côtés de la machine sont complétement dégagés, ce qui permet le montage rapide de ses éléments, notamment du cadre, de la racle et du nappeur, et procure un accès facile du dessus du plateau l'axe de pivotement étant le plus éloigné possible du plateau, celui-ci s'incline peu lorsqu'il descend. Le margeage et la mise en place de la feuille à imprimer sont facilités par l'absence totale d'obstacles; enfin, le margeage peut se faire par un opérateur étant assis. Avantageusement le dispositif de raclage et de nappage est monté en porte-à-faux sur un chariot mobile transversalement, c'est-à-dire parallèlement à l'axe d'articulation du plateau. De préférence, le cadre d'impression et le chariot supportant le dispositif de raclage et de nappage sont portés par un bâti auxiliaire qui repose sur des colonnettes ou chandelles solidaires du bàti et est maintenu sur ces chandelles par un ou plusieurs ressorts.Thanks to this arrangement, three sides of the machine are completely free, which allows rapid assembly of its elements, in particular the frame, the doctor blade and the lapper, and provides easy access from the top of the plate, the pivot axis being as far as possible from the platform, it tilts slightly when it descends. The margining and the positioning of the sheet to be printed are facilitated by the total absence of obstacles; finally, the margining can be done by an operator being seated. Advantageously, the scraping and lapping device is mounted cantilevered on a carriage movable transversely, that is to say parallel to the axis of articulation of the plate. Preferably, the printing frame and the carriage supporting the scraping and coating device are carried by an auxiliary frame which rests on small columns or candles secured to the frame and is held on these candles by one or more springs.

Dans un mode de réalisation dans lequel le plateau d'impression est constitué de manière connue par un nid d'abeilles fermé sur sa tranche avant et sur ses tranches latérales ainsi que sur ses faces supérieure et inférieure, la face supérieure étant perforée, le nid d'abeilles est percé au droit des trous de la face supérieure, de trous alignés en communication avec une chambre arrière qui est reliée à un conduit d'aspiration. Cette disposition évite de prévoir un caisson de circulation d'air sous le plateau, ce qui réduit à la fois le coût et le poids de ce dernier et permet d'augmenter sa vitesse de déplacement.In one embodiment in which the printing plate is constituted in a known manner by a closed honeycomb on its front edge and on its lateral edges as well as on its upper and lower faces, the upper face being perforated, the nest bees are drilled in line with the holes on the upper face, aligned holes in communication with a rear chamber which is connected to a suction duct. This arrangement avoids providing an air circulation box under the plate, which reduces both the cost and the weight of the latter and makes it possible to increase its speed of movement.

Le cadre d'impression est facilement démontable: il est serré par des vis sur des bras prolongeant deux de ses côtés.The printing frame is easily removable: it is tightened by screws on arms extending two of its sides.

La machine peut de la manière usuelle, être munie de cales de marge escamotables. De préférence, une cale de marge au moins est montée coulissahte dans une glissière fixée au plateau d'impression et présente, sur sa face tournée vers l'intérieur du plateau, une rainure longitudinale dans laquelle est logée avec jeu une lame longitudinale cintrée de façon que son extrémité supérieure fasse saillie horizontalement par rapport à la cale, et la lame actionne un micro-contact fixé sur la cale. Ces micro-contacts qui peuvent facilement être réglés de façon à détecter une erreur de marge de l'ordre du dixième de millimètre, sont interposés sur le circuit du contact de départ de cycle de la machine. Le cycle d'impression est ainsi empêché de se déclencher si la feuille à imprimer n'est pas correctement margée.The machine can, in the usual way, be provided with retractable margin shims. Preferably, at least one wedge wedge is slidably mounted in a slide fastened to the printing plate and has, on its face facing the inside of the plate, a longitudinal groove in which is housed with play a longitudinally curved blade that its upper end project horizontally with respect to the wedge, and the blade actuates a micro-contact fixed on the wedge. These micro-contacts which can easily be adjusted so as to detect a margin error of the order of a tenth of a millimeter, are interposed on the circuit of the start of cycle contact of the machine. The print cycle This prevents the triggering if the sheet to be printed is not properly fed.

Le dispositif de raclage et de nappage peut comprendre un support de racle et un support de nappeur montés à bascule sur un bras articulé sur le chariot, un premier vérin interposé entre le bras et le chariot, et un second vérin porté par le bras pour faire descendre l'un des supports et monter l'autre support, et inversement.The scraper and lapping device may include a doctor blade support and a lapper support rocker mounted on an arm articulated on the carriage, a first jack interposed between the arm and the carriage, and a second jack carried by the arm to make lower one of the supports and mount the other support, and vice versa.

En actionnant le second vérin, on peut ainsi baisser la racle ou lever le nappeur pour le raclage et inversement pour le nappage. Le premier vérin assure la pression de la racle ou du nappeur sur l'écran d'impression.By actuating the second cylinder, one can thus lower the doctor blade or lift the lapper for scraping and vice versa for lapping. The first cylinder ensures the pressure of the doctor blade or the layer on the printing screen.

La racle et le nappeur sont avantageusement portés chacun par un élément de liaison qui est monté oscillant avec frottement par rapport au support correspondant, autour d'un axe perpendiculaire au bras. La racle et le nappeur sont de préférence fixés par des clavettes à leur élément de liaison au support. Un changement de racle ou de nappeur peut ainsi s'effectuer en quelques secondes et ne nécessite ni outil, ni réglage.The doctor blade and the lapper are advantageously each carried by a connecting element which is mounted oscillating with friction with respect to the corresponding support, around an axis perpendicular to the arm. The doctor blade and the lapper are preferably fixed by keys to their connection element to the support. A doctor blade or lapper change can thus be carried out in a few seconds and requires no tools or adjustments.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation de la machine de sérigraphie selon l'invention, avec référence aux dessins annexés dans lesquels :

  • La Figure 1 est une vue latérale de la machine;
  • La Figure 2 en est une vue en plan, le dispositif de raclage et de nappage n'étant pas représenté;

An embodiment of the screen printing machine according to the invention has been described below, by way of non-limiting example, with reference to the appended drawings in which:
  • Figure 1 is a side view of the machine;
  • Figure 2 is a plan view, the scraper and lapping device not being shown;
  • Figure 3 is a plan view of the printing bed;
  • Figure 4 is a plan view of a margin block;
  • Figure 5 is a side view;
  • Figure 6 is an elevational view thereof;
  • Figure 7 is an end view of the device scraping and topping;
  • Figure 8 is an elevational view of part of the doctor blade.

Telle qu'elle est représentée aux Figures 1 et 2, la machine de sérigraphie selon l'invention comprend un bâti 1 portant à sa partie arrière un axe 2 qui sert de pivot à un plateau d'impression 3. Deux vérins 4 et 5 fixés l'un à l'autre par leur dos relient ce plateau au bâti, les tiges de leurs pistons étant articulées respectivement en 6 sur le plateau et en 7 sur le bâti.As shown in Figures 1 and 2, the screen printing machine according to the invention comprises a frame 1 carrying at its rear part an axis 2 which serves as a pivot to a printing plate 3. Two cylinders 4 and 5 fixed to each other by their backs connect this plate to the frame, the rods of their pistons being articulated respectively in 6 on the plate and in 7 on the frame.

Sur le bâti 1 sont fixées quatre chandelles verticales 8 portant à leur extrémité supérieure une bille de manutention 9 et, de préférence, réglables en hauteur. Sur ces billes repose un bâti auxiliaire 10 formé de deux glissières 11 de section en U, réunies l'une à l'autre par des traverses 12. Un ou plusieurs ressorts 13 dont les extrémités sont accrochées aux traverses 12 et au bâti 1 maintiennent le bâti 10 en appui sur les billes 9. Deux butées réglables 14 prévues à l'arrière du bâti 1 limitent le déplacement longitudinal du bâti 10 sous l'effet des ressorts 13. Une autre butée réglable 15 prévue sur l'un des côtés du bâti 1 détermine la position transversale du bâti 10.On the frame 1 are fixed four vertical candles 8 carrying at their upper end a handling ball 9 and, preferably, adjustable in height. On these balls rests an auxiliary frame 10 formed of two slides 11 of U-shaped section, joined to each other by crosspieces 12. One or more springs 13 whose ends are hooked to the crosspieces 12 and to the frame 1 maintain the frame 10 resting on the balls 9. Two adjustable stops 14 provided at the rear of the frame 1 limit the longitudinal movement of the frame 10 under the effect of the springs 13. Another adjustable stop 15 provided on one of the sides of the frame 1 determines the transverse position of the frame 10.

Un chariot 16 est monté coulissant sur les glissières 11 par l'intermédiaire de galets 17, d'axe horizontal, qui prennent appui sur l'aile supérieure des glissières, de part et d'autre de cette aile. Le chariot est en outre guidé transversalement par des galets 18, d'axe vertical, qui prennent appui sur un plat 19 fixé à l'une des glissières, de part et d'autre de ce plat. Un vérin de commande non représenté relie ce chariot au bâti 10.A carriage 16 is slidably mounted on the slides 11 by means of rollers 17, of horizontal axis, which bear on the upper wing of the slides, on either side of this wing. The carriage is further guided transversely by rollers 18, of vertical axis, which bear on a flat 19 fixed to one of the slides, on either side of this flat. A control jack, not shown, connects this carriage to the frame 10.

Un bras télescopique de raclage et de nappage 20 est monté pivotant en 21, en un point intermédiaire de sa longueur, sur le chariot 16 et porte un dispositif de raclage et de nappage désigné dans son ensemble par la référence 22. Un soufflet en caoutchouc 23 ou un vase en diaphragme est interposé entre l'extramité arrière du bras 20 et le chariot. Il est ainsi possible de régler les pressions de raclage et de nappage en manoeuvrant un bouton du détendeur et de les lire directement sur un manomètre.A telescopic scraper and topping arm 20 is pivotally mounted at 21, at an intermediate point of its length, on the carriage 16 and carries a scraper and topping device generally designated by the reference 22. A rubber bellows 23 or a diaphragm vessel is interposed between the rear end of the arm 20 and the carriage. It is thus possible to adjust the scraping and topping pressures by operating a button on the pressure reducer and reading them directly on a pressure gauge.

Sur l'un des côtés du bâti 10 est fixé un tube 24 dans lequel est montée pivotante une tige 25. Un cadre d'impression 26 portant une toile d'impression non représentée est fixé par des moyens de serrage 27 placés au voisinage du côté du cadre situé vers la machine à une cornière 28 solidaire de la tige 25, de façon que l'axe de cette tige se trouve dans le plan de la toile. Sur le côté opposé du bâti 10 sont prévus des moyens de serrage 29 qui permettent de maintenir en place le cadre d'impression 26. Celui-ci est donc facilement démontable, tout en étant fixe pendant l'impression.On one side of the frame 10 is fixed a tube 24 in which is pivotally mounted a rod 25. A printing frame 26 carrying a not shown printing canvas is fixed by clamping means 27 placed in the vicinity of the side from the frame located towards the machine to an angle 28 secured to the rod 25, so that the axis of this rod is in the plane of the fabric. On the opposite side of the frame 10 are provided clamping means 29 which allow the printing frame 26 to be held in place. The latter is therefore easily removable, while being fixed during printing.

On voit de la description qui précède, que le plateau d'impression et le cadre d'impression 26 sont en porte-à-faux en avant de la machine; le dispositif de raclage 22 est également en porte-à-faux. Cette disposition laisse un accès total sur les trois côtés du cadre d'impression 26, ce qui permet de marger et de retirer sans obstacles la feuille imprimée. De plus, le montage en porte-à-faux du dispositif de raclage 22 évite la présence d'une glissière devant les yeux du margeur ou au-dessus du cadre d'impression.It can be seen from the above description that the printing plate and the printing frame 26 are cantilevered in front of the machine; the scraper device 22 is also cantilevered. This arrangement leaves total access to the three sides of the printing frame 26, which allows the printed sheet to be stored and removed without obstacles. In addition, the cantilever mounting of the scraper device 22 avoids the presence of a slideway before the eyes of the feeder or above the printing frame.

Comme on le voit plus particulièrement à la Figure 3, le plateau d'impression 3 comprend une cornière 30 formant ceinture et s'étendant sur la face avant et sur les faces latérales du plateau; cette ceinture est prolongée vers l'arrière par deux bras 31 fixés à l'axe 2. Elle est fermée du côté de cet axe par un profilé 32 en U, de même hauteur qu'elle.As seen more particularly in Figure 3, the printing plate 3 comprises an angle 30 forming a belt and extending on the front face and on the lateral faces of the plate; this belt is extended rearwards by two arms 31 fixed to the axis 2. It is closed on the side of this axis by a U-shaped profile 32, of the same height as it.

L'espace délimité par la ceinture et la face avant du profilé contient un nid d'abeilles 33 sur les faces supérieure et inférieure duquel sont collées des tôles minces respectivement 34 et 35; la tôle supérieure 34 est percée de trous 36. Ce nid d'abeilles est percé de part en part par des rangées de trous 37 qui forment au droit des trous 36, des canaux débouchant dans l'espace intérieur 38 du profilé 32; cet espace forme collecteur et est relié à un conduit d'aspiration 39.The space delimited by the belt and the front face of the profile contains a honeycomb 33 on the faces upper and lower of which are bonded thin sheets 34 and 35 respectively; the upper sheet 34 is pierced with holes 36. This honeycomb is pierced right through by rows of holes 37 which form, at right angles to the holes 36, channels opening into the interior space 38 of the profile 32; this space forms a collector and is connected to a suction duct 39.

Des cales de marge sont prévues sur l'un des bords longitudinaux du plateau d'impression 3 et sur l'un de ses bords latéraux. Ces cales sont représentées schématiquement en 40 à la Figure 3.Margins are provided on one of the longitudinal edges of the printing plate 3 and on one of its lateral edges. These shims are shown schematically at 40 in Figure 3.

Dans le mode de réalisation des Figure 4 à 6, la cale de marge 41 est montée coulissante dans une glissière 42 fixée sur l'aile verticale de la ceinture 30 par des boulons 43. Sur la glissière 42 est articulé en 44 un levier 45 qui est relié par un ressort de rappel 46 et un vérin 47 à un levier 48 fixé sur la glissière. Le levier 45 porte un doigt 49 engagé dans une lumière 50 allongée transversalement de sorte que le vérin 47 permet de faire coulisser la cale 41 dans sa glissière.In the embodiment of Figures 4 to 6, the wedge wedge 41 is slidably mounted in a slide 42 fixed to the vertical wing of the belt 30 by bolts 43. On the slide 42 is articulated at 44 a lever 45 which is connected by a return spring 46 and a cylinder 47 to a lever 48 fixed on the slide. The lever 45 carries a finger 49 engaged in a slot 50 transversely elongated so that the jack 47 allows the wedge 41 to slide in its slide.

La cale 41 présente sur sa face longitudinale tournée vers la glissière, une rainure longitudinale 51 dans laquelle est logée avec jeu une lame longitudinale 52 légèrement cintrée de façon que son extrémité supérieure fasse saillie horizontalement par rapport à la cale 41 (voir Figure 5); cette lame est maintenue sur la cale, à l'une de ses extrémités, par une vis 53 qui lui laisse une légère liberté de mouvement.The wedge 41 has on its longitudinal face turned towards the slide, a longitudinal groove 51 in which is housed with play a longitudinal blade 52 slightly curved so that its upper end projects horizontally relative to the wedge 41 (see Figure 5); this blade is held on the wedge, at one of its ends, by a screw 53 which gives it a slight freedom of movement.

Une équerre 54, suffisamment mince pour présenter une certaine élasticité est fixée par les vis 55 sur la face longitudinale extérieure de la cale 41. Cette équerre comporte un micro-contact 56; des vis 57 fixent ce micro-contact sur l'équerre en même temps qu'un petit bloc 58 en une matière semi-rigide, par exemple en résine polyamide. Le bloc 58 est percé et taraudé avec un taraud ébaucheur, de façon à pouvoir recevoir une vis 59 perpendiculaire à la cale 41, en serrant légèrement sur son filet. Un doigt 60, traversant un trou 61 de la cale 41, est interposé entre la lame 52 et le bouton de commande du micro-contact 56.A bracket 54, thin enough to have a certain elasticity is fixed by the screws 55 on the outer longitudinal face of the wedge 41. This bracket comprises a micro-contact 56; screws 57 fix this micro-contact on the bracket at the same time as a small block 58 in a semi-rigid material, for example in polyamide resin. The block 58 is drilled and tapped with a roughing tap, so that it can receive a screw 59 per pendulum to wedge 41, tightening slightly on its thread. A finger 60, passing through a hole 61 in the shim 41, is interposed between the blade 52 and the microswitch control button 56.

La position du micro-contact 56 est réglée à l'aide de la vis 59 de manière qu'il établisse le contact 0,1 à 0,2mm avant que la lame 52 ne l'efface dans sa rainure 51. Le micro-contact 56 est interposé sur le circuit du contact de départ de cycle de la machine. Le cycle de départ ne se déclenchera ainsi que si la feuille à imprimer est bien margée à 0,1 ou 0,2mm près.The position of the micro-contact 56 is adjusted using the screw 59 so that it establishes the contact 0.1 to 0.2 mm before the blade 52 erases it in its groove 51. The micro-contact 56 is interposed on the circuit of the machine cycle start contact. The start cycle will only be triggered if the sheet to be printed is properly adjusted to the nearest 0.1 or 0.2mm.

Le dispositif de raclage et de nappage 22 comprend un support de racle 62 et un support de nappage 63 qui sont reliés l'un à l'autre par deux biellettes de même longueur 64 articulées respectivement en 65 et 66 sur les supports 62 et 63, chacune des biellettes étant par ailleurs articulée en son milieu sur un axe 67 qui est porté par une oreille 68 solidaire du bras 20 (voir Figure 7). Un vérin 69 est articulé sur une chape 70 solidaire du bras 20; sa tige de piston est reliée par un levier coudé 71 au support de racle 62 (Figure 1). Ce vérin permet ainsi d'amener ce support soit dans sa position active basse, soit dans sa position inactive haute, ce qui amène le support de nappeur 63 dans sa position active basse. La position basse de chacun des deux supports 62 et 63 est déterminée par des butées en caoutchouc 72 et 73 solidaires des supports et pouvant venir prendre appui sur des cornières 74 et 75 fixées sur le bras 20.The scraper and lapping device 22 comprises a doctor blade support 62 and a lapping support 63 which are connected to each other by two rods of the same length 64 articulated respectively at 65 and 66 on the supports 62 and 63, each of the links also being articulated in its middle on an axis 67 which is carried by an ear 68 secured to the arm 20 (see Figure 7). A jack 69 is articulated on a yoke 70 secured to the arm 20; its piston rod is connected by a bent lever 71 to the doctor blade support 62 (Figure 1). This jack thus makes it possible to bring this support either into its low active position or into its high inactive position, which brings the lapper support 63 into its low active position. The low position of each of the two supports 62 and 63 is determined by rubber stops 72 and 73 integral with the supports and capable of coming to bear on angles 74 and 75 fixed on the arm 20.

Le support de racle 62 est prolongé vers le bas par une plaque 76 qui est parallèle au bras 20 et sur la face arrière de laquelle un axe 77 est soudé perpendiculairement à la plaque. Sur l'axe 77 est monté oscillant un tube 78 solidaire d'une plaque 79 à la partie inférieure de laquelle est rapporté un tube 80 destiné à former palier, l'axe de ce tube étant sensiblement parallèle au bras 20. L'extrémité de l'axe 77 est filetée et reçoit un écrou 81 et un contre-écrou 82 qui maintiennent le tube 78 sur son axe 77, avec interposition de rondelles Belleville 83 qui assurent un certain freinage de l'oscillation du tube 78.The doctor blade support 62 is extended downwards by a plate 76 which is parallel to the arm 20 and on the rear face of which a pin 77 is welded perpendicular to the plate. On the axis 77 is oscillatingly mounted a tube 78 integral with a plate 79 to the lower part of which is attached a tube 80 intended to form a bearing, the axis of this tube being substantially parallel to the arm 20. The end of the axis 77 is threaded and receives a nut 81 and a lock nut 82 which hold the tube 78 on its axis 77, with the interposition of Belleville washers 83 which ensure a certain braking of the oscillation of the tube 78.

Une racle 84 peut pivoter coaxialement au tube 80. A cet effet, deux équerres 85 sont fixées à la partie inférieure de la racle, au dos de celle-ci, leur écartement étant égal à la longueur du tube 80. Ces équerres sont perforées, comme indiqué en 86, et une clavette 87 est enfilée simultanément dans les trous des équerres et dans le tube 80.A doctor blade 84 can pivot coaxially to the tube 80. For this purpose, two brackets 85 are fixed to the lower part of the doctor blade, on the back of the latter, their spacing being equal to the length of the tube 80. These brackets are perforated, as indicated in 86, and a key 87 is threaded simultaneously into the holes of the brackets and into the tube 80.

Par ailleurs, le tube 78 est solidaire d'une plaque 88 légèrement coudée et dirigée vers le haut. Une tige 89 dont l'extrémité est filetée traverse un trou de la plaque 88 et porte à son extrémité filetée un écrou moleté de réglage 90. L'autre extrémité de la tige 89 est solidaire d'un tube 91 qui est sensiblement parallèle au tube 80 et dans lequel est engagé un doigt ou clavette 92 fixé sur la face supérieure de la racle 84, parallèlement à celle-ci. Un ressort hélicoïdal 93, enfilé sur la tige 89, est interposé entre le tube 91 et la plaque 88. La manoeuvre de l'écrou 90 permet ainsi de régler l'orientation de la racle 84.Furthermore, the tube 78 is integral with a plate 88 slightly bent and directed upwards. A rod 89 the end of which is threaded passes through a hole in the plate 88 and carries at its threaded end a knurled adjusting nut 90. The other end of the rod 89 is integral with a tube 91 which is substantially parallel to the tube 80 and in which is engaged a finger or key 92 fixed on the upper face of the doctor blade 84, parallel to the latter. A helical spring 93, threaded on the rod 89, is interposed between the tube 91 and the plate 88. The operation of the nut 90 thus makes it possible to adjust the orientation of the doctor blade 84.

De son côté, le support de nappeur 63 est prolongé vers le bas par une plaque 94 sur la face arrière de laquelle est soudé un axe 95. Sur cet axe est monté oscillant un tube 96 solidaire d'une plaque 97 sur laquelle sont rapportés deux tubes 98 et 99 formant paliers. L'extrémité de l'axe 95 est filetée et reçoit un écrou 100, un contre-écrou 101 et des rondelles Belleville 102.For its part, the lapper support 63 is extended downwards by a plate 94 on the rear face of which is welded an axis 95. On this axis is mounted oscillating a tube 96 secured to a plate 97 on which are reported two tubes 98 and 99 forming bearings. The end of the axis 95 is threaded and receives a nut 100, a lock nut 101 and Belleville washers 102.

Une lame de nappage 103 est fixée à la plaque 97 par des moyens sensiblement analogues à ceux assurant la fixation de la lame de raclage 84. Une clavette 104 traverse à la fois le palier 98 et deux équerres 105 fixées à la lame. Celle-ci porte par ailleurs un doigt ou clavette 106 engagé dans le palier 99.A covering blade 103 is fixed to the plate 97 by means substantially similar to those ensuring the fixing of the scraper blade 84. A key 104 passes through both the bearing 98 and two brackets 105 fixed to the blade. It also carries a finger or key 106 engaged in the bearing 99.
