Description

La présente invention se rapporte aux appareils d'impression, utilisés notamment pour imprimer des ins­criptions sur un film dans des machines d'emballage en continu.The present invention relates to printing devices, used in particular for printing inscriptions on a film in continuous packaging machines.

On connaît déjà un appareil d'impression comprenant une tête d'impression solidaire en rotation d'un premier arbre et définissant avec un contre-rouleau une emprise pour un film, un rouleau encreur solidaire en rotation d'un deuxième arbre parallèle au premier, des moyens pour entraîner le deuxième arbre en rotation lorsque le premier arbre tourne, un moteur électrique d'entraînement du pre­mier arbre et une roue montée folle sur un troisième arbre et en contact par sa périphérie avec le film. Il faut que la vitesse linéaire du film et celle des caractères por­tés par la tête d'impression soient égales. C'est pour cela que l'on prévoit la roue de prise de vitesse, distincte de l'ap­pareil lui-même, que l'on s'efforce autant que possible de placer dans le prolongement de l'emprise, afin d'y détec­ter la vitesse du film. La vitesse de cette roue est détectée par un tachymètre, lui aussi distinct et disposé en dehors du capot de l'appareil. Le tachymètre transmet un signal de vitesse à un organe de commande de la vitesse de rotation du moteur.A printing apparatus is already known comprising a print head integral in rotation with a first shaft and defining with a counter-roller a grip for a film, an ink roller integral in rotation with a second shaft parallel to the first, means for driving the second shaft in rotation when the first shaft rotates, an electric motor for driving the first shaft and a wheel mounted idly on a third shaft and in contact by its periphery with the film. The linear speed of the film and that of the characters carried by the print head must be equal. This is why we plan the speed-taking wheel, distinct from the device itself, which we try as much as possible to place in the extension of the right-of-way, in order to detect the film speed. The speed of this wheel is detected by a tachometer, which is also separate and located outside the cover of the device. The tachometer transmits a speed signal to a motor speed control unit.

La mise en fonctionnement de l'appareil nécessite donc la mise en place, le montage et le raccordement du tachymètre et de la roue au moment de l'utilisation de l'appareil, ce qui est relativement compliqué, constitue une source d'erreurs et peut se traduire par la détection d'une valeur fausse de la vitesse. Il est difficile d'obte­nir simultanément un bon positionnement de l'appareil, assurant un bon marquage du film et un bon positionnement de la roue, assurant un bon synchronisme de la rotation de la tête et de la vitesse de défilement du film. Parfois, pour un film de faible largeur, la largeur de l'emprise est égale à celle du film. Il faut prendre l'information de vitesse à l'aide de la roue en amont ou en aval de l'em­prise. Or la vitesse du film en un tel emplacement peut être différente de la vitesse du film dans l'emprise. En­fin, le stockage et le transport de l'appareil et de ses accessoires est malaisé. Il arrive que l'un des accessoi­res se perde.Putting the device into operation therefore requires the installation, mounting and connection of the tachometer and the wheel when the device is used, which is relatively complicated, constitutes a source of errors and may result in the detection of a false speed value. It is difficult to simultaneously obtain good positioning of the device, ensuring good marking of the film and good positioning of the wheel, ensuring good synchronism of the rotation of the head and of the speed of movement of the film. Sometimes, for a narrow film, the width of the grip is equal to that of the film. The speed information must be taken using the wheel upstream or downstream of the right-of-way. However, the speed of the film in such a location may be different from the speed of the film in the grip. Finally, the storage and transport of the device and its accessories is difficult. One of the accessories may get lost.

L'invention pallie ces inconvénients par un appareil plus simple à monter et à raccorder, prenant moins de pla­ce et donc susceptible de s'intégrer plus facilement à des machines, nécessitant moins de réglages et permettant de détecter la vitesse de la laize du film dans l'emprise, même si la largeur de la laize n'est pas supérieure à celle de l'appareil et prévenant tout danger de perte des éléments constitutifs.The invention overcomes these drawbacks by a device which is simpler to assemble and connect, taking up less space and therefore capable of being more easily integrated into machines, requiring fewer adjustments and making it possible to detect the speed of the web width in the right-of-way, even if the width of the width is not greater than that of the apparatus and preventing any danger of loss of the constituent elements.

L'appareil suivant l'invention est caractérisé en ce que la roue est solidaire de l'appareil en étant montée folle sur le troisième arbre qui est incorporé à l'appareil et qui s'étend dans le plan défini par le premier arbre et par le deuxième arbre.The apparatus according to the invention is characterized in that the wheel is integral with the apparatus by being mounted idly on the third shaft which is incorporated into the apparatus and which extends in the plane defined by the first shaft and by the second tree.

Il suffit alors de mettre correctement l'appareil en position pour régler d'un coup l'impression et la dé­tection de vitesse.It then suffices to put the device correctly in position to suddenly adjust printing and speed detection.

Il pouvait sembler maladroit de ne pas confondre l'arbre de sortie du moteur et le premier arbre à entraî­ner par le moteur, avec la nécessité de prévoir un accou­plement entre eux, mais ce faisant, et notamment quand l'arbre de sortie du moteur est en dehors du plan défini par le premier arbre et par le deuxième et quand l'arbre de sortie du moteur est à une distance du premier arbre supérieure à la somme du rayon de la tête d'impression et du rayon du moteur, on peut obtenir un appareil de faible hauteur et de faible profondeur, car on tient compte ain­si du fait que deux des éléments les plus encombrants sont le moteur et le premier arbre avec la tête d'impression. Il convient donc, pour obtenir un appareil prenant peu de place, de les loger côte à côte. La place dégagée derrière la tête d'impression peut alors être mise à profit avanta­geusement pour y loger la roue de prise de vitesse et/ou le tachymètre, la roue se trouvant justement sur l'emprise.It might seem awkward not to confuse the motor output shaft and the first shaft to be driven by the motor, with the need to provide a coupling between them, but in doing so, and in particular when the motor output shaft is outside the plane defined by the first shaft and by the second and when the output shaft of the motor is at a distance from the first shaft greater than the sum of the radius of the print head and the radius of the motor, it is possible to obtain a device of low height and low depth, because it takes into account that two of the most cumbersome elements are the engine and the first shaft with the print head. It is therefore appropriate, to obtain a device taking up little space, to house them side by side. The space left behind the print head can then be used to advantage to accommodate the speed-taking wheel and / or the tachometer, the wheel being precisely on the right-of-way.

Avantageusement, le troisième arbre est confondu avec le premier.Advantageously, the third tree is confused with the first.

De préférence, le tachymètre est monté sur un qua­trième arbre, parallèle au premier et interposé entre ce­lui-ci et l'arbre de sortie du moteur, et il est prévu un accouplement entre le troisième arbre et le quatrième ar­bre. On peut ainsi loger le tachymètre sans augmenter l'épaisseur de l'appareil. Toujours pour cette même raison d'encombrement, l'axe de basculement de l'appareil, qui est parallèle au premier arbre et qui est disposé latéra­lement par rapport à l'emprise, est du même côté du pre­mier arbre que l'arbre de sortie.Preferably, the tachometer is mounted on a fourth shaft, parallel to the first and interposed between the latter and the output shaft of the engine, and there is a coupling between the third shaft and the fourth shaft. It is thus possible to accommodate the tachometer without increasing the thickness of the device. Still for this same reason for space, the tilting axis of the device, which is parallel to the first shaft and which is arranged laterally relative to the right-of-way, is on the same side of the first shaft as the output shaft .

Pour protéger la roue, la plus grande partie de celle-ci peut être logée à l'intérieur du capot. De même, le tachymètre est entièrement logé à l'intérieur du capot.To protect the wheel, most of it can be housed inside the hood. Likewise, the tachometer is fully housed inside the hood.

L'appareil d'impression représenté aux dessins, comprend un bâti 1 dans lequel sont percées cinq ouvertu­res. Dans la première, un premier arbre 2 est monté par des roule­ments 3 et des paliers 4. Dans la deuxième ouverture, est monté un deuxième arbre 5 par des roulements 6 et des pa­liers 7. Dans la troisième ouverture est monté un moteur électrique 8 ayant un arbre de sortie 9. Dans une quatriè­me ouverture est monté un codeur incrémental faisant offi­ce de génératrice tachymétrique 10,dont l'arbre porte la référence 11. Dans la cinquième ouverture passe une tige de réglage 12 faisant partie du dispositif de basculement qui sera décrit ultérieurement.The printing apparatus shown in the drawings comprises a frame 1 in which five openings are drilled. In the first, a first shaft 2 is mounted by bearings 3 and bearings 4. In the second opening, a second shaft 5 is mounted by bearings 6 and bearings 7. In the third opening is mounted an electric motor 8 having an output shaft 9. In a fourth opening is mounted an incremental encoder acting as a tachometer generator 10, the shaft of which bears the reference 11. In the fifth opening passes an adjustment rod 12 forming part of the tilting device which will be described later.

Une tête d'impression, constituée d'un porte-carac­tères 13 à éléments de chauffage incorporés 14, est montée solidaire en rotation sur l'arbre 2. Sur le même premier arbre 2, est montée folle une roue 15 de prise de vitesse. Les éléments chauffant 14 sont séparés des autres éléments constitutifs se trouvant derrière eux, par une plaque iso­lante 16. Entre la plaque 16 et la roue 15, est montée sur le premier arbre 2, une poulie 17 recevant une courroie 18 venant sur une poulie 19 montée sur l'arbre de sortie 9 du moteur 8.A print head, consisting of a character carrier 13 with incorporated heating elements 14, is mounted for rotation on the shaft 2. On the same first shaft 2, is mounted idler a wheel 15 speed. The heating elements 14 are separated from the other constituent elements behind them, by an insulating plate 16. Between the plate 16 and the wheel 15, is mounted on the first shaft 2, a pulley 17 receiving a belt 18 coming on a pulley 19 mounted on the output shaft 9 of the motor 8.

La tête d'impression 13 entraîne en rotation par frottement, par l'intermédiaire d'un joint torique 20, un rou­leau d'encrage 21 monté solidaire en rotation d'un deuxiè­me arbre 22. Les arbres 2, 5, 9 et 11 sont parallèles.The print head 13 rotates by friction, by means of an O-ring 20, an inking roller 21 mounted integral in rotation with a second shaft 22. The shafts 2, 5, 9 and 11 are parallel.

Un film F en matière plastique à imprimer, passe dans l'emprise comprise entre la tête d'impression et un contre-rouleau 23.A plastic film F to be printed passes through the area between the print head and a counter roller 23.

La roue 15 en caoutchouc entraîne par frottement un pignon 24 démultiplicateur monté sur l'arbre 11. La vitesse de rotation de l'arbre 11 est transmise au codeur 10 et transmet cette vitesse par une ligne 25 à un organe de commande 26 de la vitesse de rotation de l'arbre de sortie 9 du moteur 8. L'organe de commande 26 électroni­que est logé dans une armoire en dehors de l'appareil.The rubber wheel 15 frictionally drives a reduction pinion 24 mounted on the shaft 11. The speed of rotation of the shaft 11 is transmitted to the encoder 10 and transmits this speed by a line 25 to a speed control member 26 of rotation of the output shaft 9 of the motor 8. The electronic control member 26 is housed in a cabinet outside the device.

Un bouton moleté 27 attaque par une tige filetée 28 la tige 12, de manière à régler la force d'appui de la tête d'impression 13 sur le film F. Un taraudage d'un levier 29 engrène avec la tige filetée 28 et est monté basculant sur la plaque 1 par un axe de basculement 30 parallèle à l'arbre 9. Un bouton moleté 31 à tige filetée 32 fait saillie dans une cavité 33 de réception d'une bar­re de soutien de l'appareil, cette barre n'étant pas re­présentée et étant sensiblement parallèle à l'axe 9. En vissant plus ou moins la tige filetée 28 dans le tarauda­ge correspondant, on peut faire basculer le levier 29 au­tour de l'axe de basculement 30, de manière à faire bascu­ler plus ou moins la tête d'impression 13 vers le contre-­rouleau 23.A knurled button 27 attacks with a threaded rod 28 the rod 12, so as to adjust the pressing force of the print head 13 on the film F. A tapping of a lever 29 meshes with the threaded rod 28 and is mounted tilting on the plate 1 by a tilting axis 30 parallel to the shaft 9. A knurled button 31 with threaded rod 32 protrudes into a cavity 33 for receiving a support bar for the device, this bar does not not being shown and being substantially parallel to the axis 9. By screwing more or less the threaded rod 28 in the corresponding thread, the lever 29 can be tilted around the tilting axis 30, so as to tilt more or less minus the print head 13 towards the counter-roller 23.

Pour imprimer le film F, on fait tourner le moteur 8. L'arbre de sortie 9 du moteur entraîne par la courroie 18 le premier arbre 2. La tête d'impression 13 tourne à la vitesse du film F. Dans le même temps, la roue 15 qui frotte sur le film F est entraînée en rotation à cette mê­me vitesse, et transmet cette information de vitesse au tachymètre 10 par l'intermédiaire du pignon 24. Le tachy­mètre 10 transmet ces informations de vitesse à l'organe 26, qui règle en conséquence la vitesse du moteur 8. Dans le même temps, la tête d'impression 13 entraîne en rota­tion le rouleau encreur 21 par l'intermédiaire du joint 20.To print the film F, the motor 8 is made to rotate. The output shaft 9 of the motor drives the first shaft 2 through the belt 18. The print head 13 rotates at the speed of the film F. At the same time, the wheel 15 which rubs on the film F is rotated at this same speed, and transmits this speed information to the tachometer 10 via the pinion 24. The tachometer 10 transmits this speed information to the member 26, which accordingly adjusts the speed of the motor 8. At the same time, the print head 13 rotates the ink roller 21 via the seal 20.

La plus grande partie de la roue 13 est logée à l'intérieur d'un capot 34, dans lequel le tachymètre 10 est entièrement logé et qui entoure également tout le res­te de l'appareil, à l'exception de l'organe 26, du le­vier 29 et du contre-rouleau 23.Most of the wheel 13 is housed inside a cover 34, in which the tachometer 10 is fully housed and which also surrounds all the rest of the device, except for the member 26, the lever 29 and the counter-roller 23.

L'arbre de sortie 9 du moteur 8 est à une distance du premier arbre 2, qui est supérieure à la somme du rayon de la tête d'impression 13 et du rayon du moteur 8.The output shaft 9 of the motor 8 is at a distance from the first shaft 2, which is greater than the sum of the radius of the print head 13 and the radius of the motor 8.
