Description

Domaine techniqueTechnical area

La présente invention concerne d'une manière générale les changements des éléments d'impression dans les imprimantes du type à élément d'impression unique et plus particulièrement, la réinstallation d'une cartouche de ruban et l'accouplement et le désaccouplement d'un élément d'impression et du moteur de sélection afin de faciliter le changement de l'élément d'impression.The present invention relates generally to the changes of printing elements in printers of the single printing element type and more particularly, the reinstallation of a ribbon cartridge and the coupling and uncoupling of an element. and the selection engine to facilitate changing the print element.

Etat de la technique antérieureState of the prior art

De nombreuses imprimantes à élément d'impression unique sont actuellement disponibles dans le commerce. Les plus courantes sont les machines dites à "boule d'impression" et les machines à roue d'impression en forme de marguerite. Les systèmes d'impression IBM série 72 et à cartes magnétiques utilisent des imprimantes qui comportent dans les deux systèmes, un chariot portant un élément d'impression pouvant être basculé et entraîné en rotation pour l'impression. La différence fondamentale entre les chariots des deux systèmes indiqués ci-dessus est que dans le premier cas, l'échappement est commandé par crémaillère et cliquet alors que dans le second cas, il est commandé par cliquet et vis sans fin.Many single-element printers are currently commercially available. The most common are the so-called "ball printing" machines and machines with a daisy-shaped printing wheel. The IBM 72 series and magnetic card printing systems use printers which have in both systems a carriage with a printing element that can be tilted and rotated for printing. The fundamental difference between the carriages of the two systems indicated above is that in the first case, the exhaust is controlled by rack and pinion while in the second case, it is controlled by ratchet and worm.

L'élément d'impression utilisé dans ces deux imprimantes est suffisamment éloigné du ruban lorsque le système est stoppé pour que l'on puisse changer l'élément d'impression sans grande difficulté et sans endommager le ruban. La taille de l'élément d'impression par rapport au dispositif de déverrouillage disposé sur le haut de celui-ci, fait aussi qu'il n'est pas nécessaire de déplacer ou de retirer le ruban pour changer l'élément d'impression.The printing element used in these two printers is far enough away from the ribbon when the system is stopped so that the printing element can be changed without great difficulty and without damaging the ribbon. The size of the printing element relative to the unlocking device disposed on the top of it, also makes it unnecessary to move or remove the ribbon to change the printing element.

Une imprimante à roue d'impression en forme de marguerite utilisée couramment est celle utilisée dans le système d'impression IBM 6240 à cartes magnétiques. L'imprimante de ce système présente un chariot portant un moteur de sélection et une cartouche de ruban. le moteur de sélection comporte un moyeu sur lequel est montée la roue d'impression en forme de marguerite qui est entraînée en rotation pendant l'impression pour la sélection des caractères et dont la périphérie est pratiquement adjacente au ruban dans des condition normales.A commonly used daisy-wheel print wheel printer is that used in the IBM 6240 magnetic card printing system. The printer in this system has a carriage with a selection motor and a ribbon cartridge. the selection motor comprises a hub on which is mounted the daisy-shaped print wheel which is rotated during printing for the selection of the characters and whose periphery is practically adjacent to the ribbon under normal conditions.

Dans ce type d'imprimante, la cartouche de ruban et le ruban sont souvent disposés dans des positions gênantes lorsque l'élément d'impression doit être changé. Dans ce cas, la cartouche et le ruban doivent être retirés du chariot pour pouvoir changer l'élément d'impression sans difficulté. Une fois que le ruban a été retiré, le moteur doit être basculé ou pivoté vers le haut pour changer l'élément d'impression.In this type of printer, the ribbon cartridge and the ribbon are often placed in awkward positions when the print element needs to be changed. In this case, the cartridge and the ribbon must be removed from the carriage in order to change the print element without difficulty. Once the ribbon has been removed, the motor must be tilted or swiveled up to change the print element.

On connaît dans l'art antérieur d'autres types d'imprimantes à roue d'impression qui présentent un chariot portant un élément d'impression en forme de marguerite contenue dans une cartouche, une cartouche de ruban et un moteur de sélection.Other types of print wheel printers are known in the prior art which have a carriage carrying a daisy-shaped printing element contained in a cartridge, a ribbon cartridge and a selection motor.

Aucun de ces ensembles de l'art antérieur cités ci-dessus n'utilise un dispositif permettant le pivotement d'une cartouche de ruban dans une position non gênante, provoquant en même temps le dégagement du moteur de sélection de l'élément d'impression pour permettre le changement de ce dernier.None of these sets of the prior art cited above uses a device allowing the pivoting of a ribbon cartridge in a non-annoying position, causing at the same time the release of the motor for selecting the printing element. to allow the latter to be changed.

Exposé de l'inventionStatement of the invention

On va maintenant décrire un procédé et un dispositif facilitant le changement de l'élément d'impression dans une imprimante avec une manipulation minimale des divers éléments concernés. Une imprimante à roue d'impression en forme de marguerite comporte un moteur de sélection mobile vers et depuis un élément d'impression, une cartouche de ruban pivotante, une came et un câble raccordant le moteur de sélection à la cartouche de ruban. Elle présente également des rails d'échappement parallèles à la platine le long desquels un chariot d'imprimante,portant un moteur et un chariot porte-cartouches, peut être positionné par une vis sans fin. Le chariot d'imprimante comporte des rails excentriques réglables qui sont disposés au-dessus des rails d'échappement et perpendiculairement à ces derniers. Le moteur et le chariot porte-cartouches sont montés indépendamment sur les rails excentriques, rappelés par ressort vers la platine et mobiles le long des rails excentriques vers et depuis la platine. Le chariot porte-cartouches porte à la fois la cartouche de ruban et la cartouche d'élément d'impression. L'élément d'impression est contenu dans une cartouche d'où elle peut être retirée par dessous.We will now describe a method and a device facilitating the change of the printing element in a printer with minimal manipulation of the various elements concerned. A print wheel printer in daisy-shaped comprises a selection motor movable to and from a printing element, a pivoting ribbon cartridge, a cam and a cable connecting the selection motor to the ribbon cartridge. It also has exhaust rails parallel to the plate along which a printer carriage, carrying a motor and a cartridge holder carriage, can be positioned by a worm screw. The printer carriage has adjustable eccentric rails which are arranged above and perpendicular to the exhaust rails. The motor and the cartridge holder carriage are mounted independently on the eccentric rails, spring-loaded towards the plate and movable along the eccentric rails to and from the plate. The cartridge carrier carries both the ribbon cartridge and the print element cartridge. The printing element is contained in a cartridge from where it can be removed from below.

La cartouche d'élément d'impression est disposée dans un logement à l'avant du chariot porte-cartouches. Le logement est disposé verticalement, perpendiculairement à un plan passant par les rails d'échappement, et adjacent à la platine. La cartouche de ruban est montée pivotante sur la partie supérieure arrière du chariot porte-cartouches et disposée horizontalement au-dessus du moteur pendant l'impression. Le câble raccordant le moteur et la cartouche de ruban passe autour d'une languette à l'arrière du chariot porte-cartouches et d'une came à la partie inférieure de la cartouche de ruban. Lors du pivotement de la cartouche de ruban en position verticale, le câble et la came provoquent l'éloignement du moteur de la platine. Lors du pivotement de la cartouche de ruban dans une position horizontale sur le moteur, ce dernier peut être entraîné vers la platine par son ressort de rappel.The print element cartridge is disposed in a housing at the front of the cartridge carrier. The housing is arranged vertically, perpendicular to a plane passing through the exhaust rails, and adjacent to the plate. The ribbon cartridge is pivotally mounted on the upper rear part of the cartridge carriage and arranged horizontally above the motor during printing. The cable connecting the motor and the ribbon cartridge passes around a tab at the rear of the cartridge holder carriage and a cam at the bottom of the ribbon cartridge. When the ribbon cartridge is pivoted to the vertical position, the cable and the cam cause the motor to move away from the stage. When the ribbon cartridge pivots in a horizontal position on the motor, the latter can be driven towards the plate by its return spring.

Les surfaces 39 et 40 sont séparées par un intervalle tel qu'elles sont toujours en contact avec le rail excentrique 6. Le support de montage 37 présente également un évidement à surface supérieure 41 et à surfaces angulaires 42 et 43. L'intervalle séparant les surfaces angulaires 42 et 43 du support 37 est plus important que celui séparant les surfaces angulaires 39 et 40 du support 36. Ceci permet la rotation des rails excentriques qui restent en contact avec les surfaces angulaires 39 et 40 et la surface supérieure 41. En outre, le chariot 10 présente des supports de montage similaire aux supports 36 et 37 sous son côté arrière 21. Le moteur 7 comporte un boîtier avant 44 présentant des supports de montage à évidements similaires à ceux des supports de montage 36 et 37.

The mounting support 36 has a recess with upper surface 38 and angular surfaces 39 and 40. The surfaces 39 and 40 are separated by an interval such that they are always in contact with the eccentric rail 6. The mounting support 37 also has a recess with upper surface 41 and angular surfaces 42 and 43. The interval separating the angular surfaces 42 and 43 of the support 37 is more important than that separating the angular surfaces 39 and 40 from the support 36. This allows the rotation of the eccentric rails which remain in contact with the angular surfaces 39 and 40 and the upper surface 41. Furthermore , the carriage 10 has mounting supports similar to the supports 36 and 37 under its rear side 21. The motor 7 comprises a front housing 44 having mounting supports with recesses similar to those of the mounting supports 36 and 37. The motor 7 also includes a rear housing 45 similar to the housing 44.

Lors de la rotation des rails excentriques, le moteur 7 et le chariot 10 sont orientés par rapport à la platine 5. L'orientation peut être déterminée par l'inclinaison sur le côté du chariot 10 suivant différents angles de rotation des rails excentriques. L'orientation peut également être verticale suivant les mêmes angles de rotation des rails excentriques.During the rotation of the eccentric rails, the motor 7 and the carriage 10 are oriented relative to the plate 5. The orientation can be determined by the inclination on the side of the carriage 10 according to different angles of rotation of the eccentric rails. The orientation can also be vertical according to the same angles of rotation of the eccentric rails.

On se reportera maintenant à la fois aux Figures 1 et 2. Le côté arrière 21 du chariot 10 comporte une languette 22. Un taraudage 24 est ménagé sous la languette 22 du chariot et est aligné avec le trou 23 percé dans le chariot 1. La vis 46 traversant librement le trou 23 du chariot 1 est vissée dans le taraudage 24 du chariot 10 et assure le positionnement du chariot sur les rails excentriques par rapport au chariot 1.We will now refer to both Figures 1 and 2. The rear side 21 of the carriage 10 has a tongue 22. A thread 24 is provided under the tongue 22 of the carriage and is aligned with the hole 23 drilled in the carriage 1. The screw 46 freely passing through the hole 23 of the carriage 1 is screwed into the internal thread 24 of the carriage 10 and ensures the positioning of the carriage on the eccentric rails relative to the carriage 1.

Des éléments cylindriques ou détentes sont disposés dans les évidements 18 et 19 des supports 16 et 17, tel que la détente 48 dans l'évidement 18. La détente 48 reçoit la tige 49 autour de laquelle pivote le mécanisme de cartouche de ruban 20. La cartouche 20 peut pivoter entre une position horizontale représentée en traits pleins et une position verticale 69 représentée en tirets. La cartouche 20 comporte un certain nombre de moyeux de guidage et d'entraînement tels que les moyeux 67 et 68.Cylindrical or detent elements are disposed in the recesses 18 and 19 of the supports 16 and 17, such as the trigger 48 in the recess 18. The trigger 48 receives the rod 49 around which pivots the ribbon cartridge mechanism 20. The cartridge 20 can pivot between a horizontal position shown in solid lines and a vertical position 69 shown in dashes. The cartridge 20 includes a number of guide and drive hubs such as the hubs 67 and 68.

Une vis d'ancrage 50 est vissée dans le côté arrière 51 du moteur 7 et comporte un crochet de câble 52 à son extrémité gauche. Le crochet 52 reçoit un embout de retenue 53 solidaire du câble 54. Le câble 54 est disposé autour de la languette 22, traverse la découpe 55 ménagée dans le chariot 10 et est raccordé à la partie protubérante 56 du fond du mécanisme de cartouche de ruban 20. Une came 66 est en contact avec le câble 54 et est fixée à l'extrémité inférieure gauche du mécanisme de cartouche 20. La came 66 et la cartouche 20 pivotent autour de la tige 49. La languette 22 maintient le câble 54 tendu et dégagé de la came 66 lorsque la cartouche 20 est en position horizontale. Lorsque celle-ci est pivotée en position verticale, le câble 54 est partiellement enroulé autour de la came 66.An anchor screw 50 is screwed into the rear side 51 of the motor 7 and has a cable hook 52 at its left end. The hook 52 receives a retaining tip 53 integral with the cable 54. The cable 54 is disposed around the tongue 22, passes through the cutout 55 in the carriage 10 and is connected to the protruding part 56 of the bottom of the ribbon cartridge mechanism 20. A cam 66 is in contact with the cable 54 and is fixed to the lower left end of the cartridge mechanism 20. The cam 66 and the cartridge 20 pivot around the rod 49. The tongue 22 keeps the cable 54 taut and disengaged from the cam 66 when the cartridge 20 is in the horizontal position. When the latter is pivoted in a vertical position, the cable 54 is partially wound around the cam 66.

Lorsque la cartouche 20 est en position horizontale, le ruban contenu dans celle-ci est disposé derrière l'écran presse-papier 9 et en position d'impression. Disposés ainsi, le ruban et la cartouche 20 sont dans une position gênante pour un changement de l'élément d'impression, pour l'entretien de l'imprimante, etc...When the cartridge 20 is in the horizontal position, the ribbon contained therein is disposed behind the clipboard screen 9 and in the printing position. Arranged thus, the ribbon and the cartridge 20 are in an awkward position for a change of the printing element, for the maintenance of the printer, etc.

Lorsque l'on désire pivoter la cartouche 20 de sa position horizontale à sa position verticale afin de retirer la cartouche d'élément d'impression 8 du logement 11 et/ou d'installer une autre cartouche dans ledit logement 11, on actionne un verrou 100 qui peut être une lame flexible en "L" fixée au boîtier du moteur 7. Un support de montage de marteau de frappe 59 est prévu à la droite du verrou 100 et est raccordé au boîtier avant 63 du moteur 7.When it is desired to rotate the cartridge 20 from its horizontal position to its vertical position in order to remove the print element cartridge 8 from the housing 11 and / or to install another cartridge in said housing 11, a lock is actuated 100 which can be a flexible L-shaped blade fixed to the motor housing 7. A striking hammer mounting support 59 is provided to the right of the latch 100 and is connected to the front housing 63 of the motor 7.

Comme indiqué ci-dessus, lors du pivotement de la cartouche 20 de sa position horizontale à sa position verticale, le câble 54 s'enroule autour de la came 66 qui provoque le déplacement horizontal vers la gauche du moteur 7 à la position 70 représenté en tirets. Ce déplacement du moteur 7 provoque le déplacement vers la gauche du moyeu d'entraînement 13 fixé à l'arbre du moteur de sélection 12, à la position 71 représentée en tirets. La vis d'ancrage 01 50 est réglable dans le côté arrière 51 pour ajuster la position du moteur 7, lorsque celui-ci est en position d'impression, par rapport à la platine. Lors du déplacement du moyeu 13 vers la gauche, le moyeu 13 se dégage de la roue d'impression en forme de marguerite (non représentée) logée dans la cartouche 8. Le moyeu d'entraînement 13 est fixé à l'extrémité-62 de l'arbre 12 et comporte un prolongement 60 qui présente un doigt d'entraînement décalé 61. Il est souhaitable de maintenir le moyeu d'entraînement 13 en position de repos pendant son déplacement et celui du moteur lors du pivotement de la cartouche 20 et l'élément d'arrêt 58 est prévu dans ce but.As indicated above, during the pivoting of the cartridge 20 from its horizontal position to its vertical position, the cable 54 is wound around the cam 66 which causes the horizontal displacement to the left of the motor 7 to the position 70 shown in dashes. This displacement of the motor 7 causes the displacement to the left of the drive hub 13 fixed to the shaft of the selection motor 12, at position 71 shown in dashes. The anchor screw 01 50 is adjustable in the rear side 51 to adjust the position of the motor 7, when the latter is in the printing position, relative to the plate. When the hub 13 moves to the left, the hub 13 emerges from the daisy-shaped print wheel (not shown) housed in the cartridge 8. The drive hub 13 is fixed to the end-62 of the shaft 12 and has an extension 60 which has an offset drive finger 61. It is desirable to keep the drive hub 13 in the rest position during its movement and that of the motor during the pivoting of the cartridge 20 and l 'Stop member 58 is provided for this purpose.

Le bâti moteur avant 44 est porté par le capot moteur avant 63. Le téton de positionnement 57 maintient connecté au support de montage avant du moteur 44 la cartouche 8 en position dans son logement 11 et est logé dans une ouverture 65 de la cartouche 8. A la suite d'un retrait de la cartouche 8 et/ou de l'introduction d'une autre cartouche d'élément d'impression dans le logement 11, la cartouche 20 est basculée en arrière pour la ramener dans sa position horizontale. Ceci permet le passage du moteur 7 de sa position 70 représentée en tirets à sa position représentée en traits pleins. Le mouvement du moteur 7 est assuré par les ressorts 29 et 30. Lors du mouvement du moteur 7 vers la droite, le téton 57 est introduit dans l'ouverture 65 pour positionner la cartouche 8 et la bloquer dans cette position.The front engine mount 44 is carried by the front engine cover 63. The positioning pin 57 keeps the cartridge 8 in position in its housing 11 and connected to the front mounting support of the engine 44 and is housed in an opening 65 in the cartridge 8. Following removal of the cartridge 8 and / or introduction of another print element cartridge into the housing 11, the cartridge 20 is tilted back to return it to its horizontal position. This allows the motor 7 to pass from its position 70 shown in dashes to its position shown in solid lines. The movement of the motor 7 is provided by the springs 29 and 30. During the movement of the motor 7 to the right, the stud 57 is introduced into the opening 65 to position the cartridge 8 and lock it in this position.

Bien que l'on ait décrit dans ce qui précède et représenté sur les dessins les caractéristiques essentielles de l'invention appliquées à un mode de réalisation préféré de celle-ci, il est évident que l'homme de l'art peut y apporter toutes modifications de forme ou de détail qu'il juge utiles, sans pour autant sortir du cadre de ladite invention.Although the essential characteristics of the invention applied to a preferred embodiment of the invention have been described in the foregoing and represented in the drawings, it is obvious that a person skilled in the art can provide all of them. modifications of form or detail which he judges useful, without departing from the scope of said invention.
