En fig. 1 à 6, la référence 1 désigne un magasin vertical monté à poste fixe sur le bâti général de la machine, bâti qu'on a représenté en 2 sur le tracé interrompu de fig. 6. Ce magasin 1 s'ouvre vers le haut afin de recevoir une pile de feuilles auto-collantes 3, celles-ci étant retenues par des rebords inférieurs 1ª prévus au niveau de l'ouverture du bas dudit magasin. Au-dessous de ce dernier, le bâti 2 supporte une table horizontale ajourée 4, qu'on peut supposer être formée par deux longe­rons parallèles espacés transversalement l'un de l'autre.In fig. 1 to 6, the reference 1 designates a vertical magazine mounted on a fixed station on the general frame of the machine, frame which has been shown at 2 on the broken line in FIG. 6. This magazine 1 opens upwards in order to receive a stack of self-adhesive sheets 3, these being retained by lower flanges 1ª provided at the opening of the bottom of said magazine. Below the latter, the frame 2 supports a perforated horizontal table 4, which can be assumed to be formed by two parallel beams spaced transversely from one another.

A l'opposé du magasin 1, le bâti 2 supporte deux tiges horizontales su­perposées 5 formant guides de coulissement pour un chariot 6. Comme mon­tré en fig. 7, contre ce chariot 6 est fixé le cylindre 7 d'un vérin à deux courses dans les deux sens, dont l'organe mobile 8 est solidaire d'une traverse horizontale 9, laquelle réunit deux colonnes 10 mobiles à l'intérieur de colliers ou brides 11 rapportés contre le chariot 6. Les colonnes 10 se prolongent vers le bas au-dessous de la table 4 pour por­ter une console 12 formant support pour une série de ventouses 13, agen­cées pour passer à travers la table 4 et reliées par une canalisation flexible (non représentée) à une source d'aspiration convenablement com­mandée.Opposite the magazine 1, the frame 2 supports two superimposed horizontal rods 5 forming sliding guides for a carriage 6. As shown in fig. 7, against this carriage 6 is fixed the cylinder 7 of a two-stroke cylinder in both directions, the movable member 8 is integral with a horizontal cross member 9, which joins two columns 10 movable inside of collars or flanges 11 attached to the carriage 6. The columns 10 extend down below the table 4 to carry a console 12 forming a support for a series of suction cups 13, arranged to pass through the table 4 and connected by a flexible pipe (not shown) to a suitably controlled suction source.

L'ensemble constitué par les ventouses 13 et le vérin 7-8 destiné à leur actionnement vertical par rapport au chariot 6 forme le mécanisme de prélèvement dont le rôle et le fonctionnement seront exposés plus loin.The assembly constituted by the suction cups 13 and the cylinder 7-8 intended for their vertical actuation relative to the carriage 6 forms the sampling mechanism whose role and operation will be explained below.

Le chariot 6 supporte également une plaque de maintien 14 équipée d'une multitude de petites ventouses pneumatiques à axe vertical, reliées par une canalisation flexible 15 à la source d'aspiration précitée. Cette plaque 14 est portée par deux colonnes 16 qui coulissent dans des col­liers 17 du chariot 6 et qui sont réunies par une traverse 18 fixée à l'organe mobile 19 d'un vérin à axe vertical dont le cylindre 20 est fixé contre le chariot 6. Comme le vérin 7-8, ce vérin 19-20 est agencé de manière à comporter deux courses différentes à la montée comme à la descente.The carriage 6 also supports a retaining plate 14 equipped with a multitude of small pneumatic suction cups with vertical axis, connected by a flexible pipe 15 to the aforementioned suction source. This plate 14 is carried by two columns 16 which slide in collars 17 of the carriage 6 and which are joined by a cross member 18 fixed to the movable member 19 of a jack with a vertical axis whose cylinder 20 is fixed against the carriage 6 Like the cylinder 7-8, this cylinder 19-20 is arranged so as to comprise two different strokes for the ascent as for the descent.

En avant de la table horizontale 4, la machine comporte le dispositif de taquage 21 représenté en fig. 8. Ce dispositif comprend une butée longi­tudinale fixe 22, susceptible d'être réglée en position parallèlement à la table 4 en fonction des dimensions des feuilles 3 à distribuer ; à cette butée longitudinale fixe 22 est associée une double butée trans­versale fixe 23. Pour le déplacement de la feuille 3 posée sur la table 4, il est prévu deux taquets mobiles longitudinaux 24 et un taquet mobi­le transversal 25 ; chacun de ces taquets mobiles est pourvu d'une queue qui coulisse dans un dé 26 et qui dépasse en arrière de ce dernier pour coopérer avec un cône d'actionnement 27 porté par une tige 28, laquelle est solidaire de l'organe mobile d'un vérin d'actionnement 29.In front of the horizontal table 4, the machine includes the jogging device 21 shown in FIG. 8. This device comprises a fixed longitudinal stop 22, capable of being adjusted in position parallel to the table 4 as a function of the dimensions of the sheets 3 to be distributed; associated with this fixed longitudinal stop 22 is a double fixed transverse stop 23. For the movement of the sheet 3 placed on the table 4, two longitudinal movable tabs 24 and a transverse movable stop 25 are provided; each of these movable tabs is provided with a tail which slides in a die 26 and which protrudes behind the latter to cooperate with an actuating cone 27 carried by a rod 28, which is integral with the movable member of an actuating cylinder 29.

On comprend que lorsque les deux vérins 29 associés aux cônes 27 sont actionnés, ces derniers repoussent la feuille 3 dans les deux sens pour amener, par portée des taquets 24 et 25, les bords de celle-ci contre les butées fixes 22 et 23, en opérant par taquage le positionnement précis de ladite feuille sur la table 4. Des ressorts de rappel associés aux dés 26 assurent le rappel des taquets mobiles à la position reculée.It will be understood that when the two jacks 29 associated with the cones 27 are actuated, the latter push the sheet 3 back and forth in order to bring the edges of the latter against the fixed stops 22 and 23 by bearing of the tabs 24 and 25, by operating by jogging the precise positioning of said sheet on the table 4. Return springs associated with the dice 26 ensure the return of the movable lugs to the retracted position.

En fait la double butée transversale fixe 23 est portée par le mors fixe 30 d'un mécanisme de pince représenté de manière plus détaillée en fig. 9 et 10. Ce mors fixe 30 est monté sur un chariot 31 qui coulisse le long de deux guides parallèles 32 rapportés obliquement contre le bâti 2 à l'aide de colliers 33. Au mors fixe 30 est associé un mors mobile 34 qui est solidaire d'un arbre de commande 35 pourvu en bout d'un levier 36 attelé à l'organe mobile d'un vérin de manoeuvre 37, tout cet ensemble étant bien entendu supporté par le chariot 31.In fact, the double fixed transverse stop 23 is carried by the fixed jaw 30 of a clamp mechanism shown in more detail in FIG. 9 and 10. This fixed jaw 30 is mounted on a carriage 31 which slides along two parallel guides 32 brought obliquely against the frame 2 using collars 33. With the fixed jaw 30 is associated a mobile jaw 34 which is integral a control shaft 35 provided at the end of a lever 36 coupled to the movable member of an actuating cylinder 37, all this assembly of course being supported by the carriage 31.

Il convient d'observer que ce chariot porte-pince 31 est réuni au cha­riot principal 6 de la machine par une chaîne 38 formée par deux brins opposés fixés audit chariot 31 par une attache 39 (fig. 9). L'un des brins est renvoyé horizontalement par une roue 40 (fig. 1) en direction du chariot 2 équipé à cet effet d'une attache 41 (fig. 7). Une attache équivalente 42 est prévue sur ce chariot 6 pour lui arrimer le brin opposé qui est renvoyé en direction de l'attache 39 du chariot 31 par deux roues 43 et 44 (fig. 1), cette dernière étant entraînée en rotation par un moto-réducteur 45, alternativement dans un sens et dans l'autre.It should be observed that this clamp holder carriage 31 is joined to the main carriage 6 of the machine by a chain 38 formed by two opposite strands fixed to said carriage 31 by a clip 39 (FIG. 9). One of the strands is returned horizontally by a wheel 40 (fig. 1) in the direction of the carriage 2 equipped for this purpose with a fastener 41 (fig. 7). An equivalent attachment 42 is provided on this carriage 6 to secure the opposite strand which is returned towards the attachment 39 of the carriage 31 by two wheels 43 and 44 (fig. 1), the latter being driven in rotation by a motorcycle. -reducer 45, alternately in one direction and in the other.

On conçoit dans ces conditions que les deux chariots 6 et 31 se dépla­cent en même temps et dans le même sens, en fonction du sens de rotation imparti à la roue inférieure 44 par le moto-réducteur 45. Il va de soi que le déplacement simultané alternatif de ces deux chariots pourrait être réalisé à l'aide d'un vérin hydraulique à double effet, agissant sur l'un des chariots soit de manière directe, soit à travers un système d'attelage à fléau ou équivalent.It is understood under these conditions that the two carriages 6 and 31 move at the same time and in the same direction, depending on the direction of rotation imparted to the lower wheel 44 by the gear motor 45. It goes without saying that the simultaneous movement alternative of these two carriages could be achieved using a double-acting hydraulic cylinder, acting on one of the carriages either directly, or through a beam coupling system or equivalent.

la machine comprend encore un dispositif 46 (fig. 9) agencé de manière à éliminer de la pince le cache de protection saisi par le mors mobile 34 de celle-ci. Ce dispositif 46 est manoeuvré à l'aide d'un vérin 47 dont l'organe mobile porte une crémaillère 48 qui est guidée par un galet 49 et qui engrène avec un pignon 50. Comme plus particulièrement visible en fig. 10, ce pignon 50 est solidaire d'un bras 51 qui est contre-coudé de façon à ce que son extrémité libre vienne se disposer parallèlement à l'arbre 35 qui porte le mors mobile 34.the machine also comprises a device 46 (fig. 9) arranged so as to eliminate from the clamp the protective cover gripped by the movable jaw 34 thereof. This device 46 is operated using a jack 47, the movable member of which carries a rack 48 which is guided by a roller 49 and which meshes with a pinion 50. As more particularly visible in FIG. 10, this pinion 50 is integral with an arm 51 which is counter-bent so that its free end comes to be arranged parallel to the shaft 35 which carries the movable jaw 34.

La machine représentée est enfin dotée d'un plateau élévateur 52 (fig. 1) fixé sur l'organe mobile d'un vérin 53 à axe vertical.The machine shown is finally provided with a lifting plate 52 (fig. 1) fixed on the movable member of a jack 53 with a vertical axis.

Pour exposer le fonctionnement de la machine, on se reportera tout d'abord au schéma suivant fig. 1 où l'on a supposé :

    - que le chariot principal 6 est à la position reculée pour laquel­le le mécanisme de prélèvement à ventouses se trouve disposé au-dessous du magasin 1 ;

    - que la console porte-ventouses 12 se trouve en position basse, les ventouses 13 étant ainsi situées au-dessous de la table ajourée 4 ;

    - que la plaque de maintien 14 est en position haute, au-dessus d'une feuille auto-collante 3 préalablement déposée sur la table 4 ;

    - et que le chariot 31 du mécanisme de pince est en position haute au niveau de l'extrémité antérieure de la table 4, avec le mors mobile 34 à la position ouverte.To explain how the machine works, first refer to the following diagram in fig. 1 where we assumed:

- That the main carriage 6 is in the retracted position for which the suction cup sampling mechanism is located below the magazine 1;

- That the suction cup console 12 is in the low position, the suction cups 13 thus being located below the perforated table 4;

- That the retaining plate 14 is in the high position, above a self-adhesive sheet 3 previously deposited on the table 4;

- And that the carriage 31 of the clamp mechanism is in the high position at the front end of the table 4, with the movable jaw 34 in the open position.

Le vérin 7-8 est alors commandé de sorte que les ventouses 13, reliées à la source d'aspiration, viennent prélever à la base du magasin 1 la feuille auto-collante 3 inférieure, comme illustré en fig. 2. La plaque 14 s'abaisse sous l'effet du vérin 19-20 et vient s'arrêter à quelques millimètres de la feuille 3 supportée par la table 4. Les vérins 29 sont alimentés, de sorte que les taquets mobiles 24 et 25 opèrent le taquage de cette feuille 3 qui de ce fait se trouve parfaitement positionnée contre les butées fixes 22 et 23.The cylinder 7-8 is then controlled so that the suction cups 13, connected to the suction source, come to take from the base of the magazine 1 the lower self-adhesive sheet 3, as illustrated in FIG. 2. The plate 14 lowers under the effect of the cylinder 19-20 and comes to stop a few millimeters from the sheet 3 supported by the table 4. The cylinders 29 are supplied, so that the movable tabs 24 and 25 operate the jogging of this sheet 3 which is therefore perfectly positioned against the fixed stops 22 and 23.

La console porte-ventouses 12 est alors actionnée vers le bas (fig. 3) jusqu'à amener la feuille prélevée 3 immédiatement au-dessus de la table 4. Simultanément, la plaque 14 effectue un second mouvement de descente en même temps que sa canalisation 15 est reliée à la source d'aspira­tion, si bien que la feuille 3 qui se trouvait sur la table 4 est ferme­ment retenue en place. Le vérin 37 du mécanisme de pince est actionné, ce qui a pour effet de refermer le mors mobile 34 contre le bord anté­rieur débordant du cache de protection 3ª de la feuille 3. Un article à revêtir 54 est disposé sur le plateau élévateur 52 alors à la position basse.The suction cup console 12 is then actuated downwards (fig. 3) until the sampled sheet 3 is brought immediately above the table 4. Simultaneously, the plate 14 performs a second downward movement at the same time as its line 15 is connected to the suction source, so that the sheet 3 which was on the table 4 is firmly held in place. The cylinder 37 of the clamp mechanism is actuated, which has the effect of closing the movable jaw 34 against the anterior edge projecting from the protective cover 3ª of the sheet 3. An article to be coated 54 is placed on the lifting plate 52 then at the low position.

Le moto-réducteur 45 est alors mis en marche et la chaîne 38 déplace en conséquence le chariot principal 6 d'arrière en avant (c'est-à-dire de gauche à droite en fig. 4), et le chariot porte-pince 31 obliquement vers le bas (de droite à gauche). Le cache de protection 3ª saisi par la pince 30-34 est en conséquence détaché de la feuille 3 proprement dite qui reste solidaire de la plaque de maintien 14. Le vérin 53 est alimenté afin que le plateau 52 et l'article 54 entament leur mouvement ascendant.The gear motor 45 is then started and the chain 38 consequently displaces the main carriage 6 from back to front (that is to say from left to right in FIG. 4), and the clamp-carrying carriage 31 obliquely down (from right to left). The protective cover 3ª gripped by the clamp 30-34 is consequently detached from the sheet 3 proper which remains integral with the retaining plate 14. The jack 53 is supplied so that the plate 52 and the article 54 begin their movement ascending.

Le déplacement du chariot 6 a bien entendu amené la console porte-­ventouses 12 à la position avancée sur la table 4 ; l'aspiration est coupée de telle sorte que les ventouses 13 déposent sur la table la feuille 3 qui se trouve ainsi à la même position que celle initialement envisagée en fig. 1. A la fin du mouvement ascendant du plateau 52, l'article 54 vient s'appliquer contre la face inférieure collante de la feuille 3 (fig. 5) qui est alors libérée par la plaque 14, la canalisa­tion 15 de celle-ci ayant été fermée. Le chariot porte-pince 51 arrive en position basse, le mors mobile 34 s'ouvre et le vérin 47 manoeuvre le bras 51 qui par tournoiement élimine le cache 3ª.The movement of the carriage 6 has of course brought the suction cup console 12 to the advanced position on the table 4; the suction is cut off so that the suction cups 13 deposit on the table the sheet 3 which is thus in the same position as that initially envisaged in FIG. 1. At the end of the upward movement of the plate 52, the article 54 is applied against the sticky underside of the sheet 3 (fig. 5) which is then released by the plate 14, the pipe 15 thereof having been closed. The clamp-carrying carriage 51 arrives in the low position, the movable jaw 34 opens and the actuator 47 operates the arm 51 which by turning eliminates the cover 3ª.

Les chariots 6 et 31 sont ramenés à leur position initiale en même temps que le vérin 53 abaisse le plateau 52 ; les vérins 7-8 et 19-20 sont actionnés pour ramener le porte-ventouses 12 et la plaque 14 à leur position initiale. L'article 54 muni de la feuille auto-collante 3 peut être dirigé vers un poste ultérieur, manuel ou automatique, qui assure la mise en place complète de la feuille 3 précitée. La machine est alors prête pour un nouveau cycle opératoire.The carriages 6 and 31 are returned to their initial position at the same time as the jack 53 lowers the plate 52; cylinders 7-8 and 19-20 are actuated to return the suction cup holder 12 and the plate 14 to their initial position. The article 54 provided with the self-adhesive sheet 3 can be directed to a subsequent station, manual or automatic, which ensures the complete positioning of the aforementioned sheet 3. The machine is then ready for a new operating cycle.

On conçoit que l'ensemble des opérations du processus est susceptible d'être commandé à l'aide d'un programmateur de façon à ce qu'elles se déroulent de manière automatique suivant la séquence ci-dessus exposée.It is understood that all of the operations of the process can be controlled using a programmer so that they take place automatically according to the sequence described above.
