Dans la suite de la description, les termes relatifs à une direction ou à une position, s'entendent par rapport à une machine à relier en position de fonctionnement. En particulier, l'avant de la machine à relier est situé du côté où sont insérés les paquets de feuilles perforées.In the remainder of the description, the terms relating to a direction or a position, refer to a binding machine in the operating position. In particular, the front of the binding machine is located on the side where the packets of perforated sheets are inserted.
La
La machine à relier 100 est commandée par une unité centrale qui est programmable par l'intermédiaire d'une interface qui prend ici la forme d'un tableau de commande 108.The binding
La machine à relier 100 peut également comprendre en amont de la table d'alignement 106, un poste d'alimentation automatique 102 prévu pour alimenter automatiquement le module de reliure 104 en paquets de feuilles perforées.The binding
La machine à relier 100 est particulièrement adaptée pour être utilisée avec des éléments de reliure 206 dont un exemple est représenté sur la
La machine à relier 100 comprend de préférence un module d'alimentation en bande d'élément de reliure et un module de découpe de la bande en éléments de reliure 206. Les éléments de reliure 206 se présentent sous la forme d'une bande de grande longueur, de préférence conditionnée sous forme d'une bobine. La bande est déroulée au poste d'alimentation et pénètre dans le poste de découpe où elle est découpée en série d'éléments de reliure 206. La longueur de chaque série d'élément de reliure 206 est déterminée en fonction des dimensions du paquet de feuilles perforées à relier. En fonction du type de paquet de feuilles perforées à relier, il est possible qu'une seule série d'éléments de reliure 206 soit suffisante, mais il est également possible que plusieurs séries soient nécessaires.The binding

Le module de reliure 104 comprend un châssis constitué ici de deux plaques parallèles 202 et 203 sur lequel les différents éléments constituant le module de reliure 104 sont fixés.The
Dans le mode de réalisation de l'invention présenté sur la
Les éléments de reliure 206 sont réceptionnés en sortie du passage 222 par un ensemble de transfert comprenant une courroie de transfert 208. L'ensemble de transfert comprend des moyens de déplacement qui le rendent mobile entre une position de dégagement et une position d'engagement. Dans la position d'engagement, la courroie de transfert 208 est disposée dans une zone de fermeture pour positionner les éléments de reliure 206. Dans la position de dégagement, la courroie de transfert 208 est disposée pour recevoir les éléments de reliure 206 en sortie du passage 222 et pour être dégagée de la zone de fermeture. La courroie 208 prend la forme d'une boucle fermée qui est entraînée dans un plan horizontal par deux roues à axe vertical. La courroie de transfert 208 comprend ainsi deux sections rectilignes et deux sections courbes. La courroie de transfert 208 est prévue pour fixer magnétiquement les éléments de reliure 206 au niveau de leurs zones intermédiaires 606.The
Dans un mode de réalisation préféré, les moyens de déplacement de l'ensemble de transfert sont prévus pour déplacer ledit ensemble de transfert, et donc la courroie de transfert 208, en translation dans un plan horizontal.In a preferred embodiment, the transfer means of the transfer assembly are provided for moving said transfer assembly, and thus the
La zone de fermeture est disposée à l'avant du module de reliure et en amont de la courroie de transfert 208, au niveau de moyens de fermeture qui sont ici constitués d'une mâchoire de fermeture inférieure 218 et d'une mâchoire de fermeture supérieure 214 disposée au-dessus de la mâchoire de fermeture inférieure 218. Le rapprochement de la mâchoire de fermeture supérieure 214 de la mâchoire de fermeture inférieure 218 entraîne l'écrasement des éléments de reliure 206 qui se ferment sous une forme annulaire par rapprochement des pointes 604 au voisinage des bases 602.The closure zone is disposed at the front of the binding module and upstream of the
En amont de la zone de fermeture et donc des moyens de fermeture, est disposé un ensemble de guidage prévu pour guider le paquet de feuilles perforées 204 lorsqu'il est inséré dans le module de reliure 104. L'ensemble de guidage comprend une table de reliure 216 sur laquelle repose le paquet de feuilles perforées 204 et un guide supérieur 210 disposé au-dessus de la table de reliure 216. Le paquet de feuilles perforées 204 s'insère entre la table de reliure 216 et le guide supérieur 210.Upstream of the closure zone and thus of the closing means, there is arranged a guide assembly designed to guide the packet of
Comme cela est expliqué ci-après, la table de reliure 216 et le guide supérieur 210 présentent chacun une zone de fixation, l'une des zones de fixation étant prévue pour maintenir l'une des séries des extrémités des éléments de reliure 206 et l'autre zone de fixation étant prévue pour maintenir l'autre série d'extrémités des éléments de reliure 206.As explained below, the binding table 216 and the
Chaque zone de fixation est aimantée. A cette fin, dans le mode de réalisation de l'invention présenté ici, la table de reliure 216 et le guide supérieur 210 portent une barrette d'aimants 212.Each attachment area is magnetized. For this purpose, in the embodiment of the invention presented here, the binding table 216 and the
La mise en place d'un guide supérieur 210 et d'une table de reliure 216 aimantés permet de maintenir les éléments de reliure 206 quelque soit leur diamètre. Les éléments de reliure 206 étant ainsi maintenus, la fermeture des éléments de reliure 206 peut alors se faire de manière aisée et rapide puisqu'il n'y a pas de risque que les éléments de reliure 206 et en particulier leurs extrémités, bougent lors de la mise en place du paquet de feuilles perforées 204 et de leur fermeture. Il n'est donc pas nécessaire d'introduire les pointes 604 dans les perforations, cette introduction s'effectuant de manière automatique lors de l'écrasement des éléments de reliure 206.The establishment of a magnetic
Le maintien des bases 602 et des pointes 604 par le guide supérieur 210 et la table de reliure 216 permet également d'avoir une unique mâchoire de fermeture supérieure 214 et ceci quelque soit le diamètre des éléments de reliure 206. En effet, les mâchoires 218 et 214 ne jouent aucun rôle dans le maintien des éléments de reliure 206, il n'est donc pas nécessaire d'adapter leurs formes à celles des éléments de reliure 206.Maintaining the
Le positionnement en profondeur du paquet de feuilles perforées 204 dans le module de reliure 104, c'est-à-dire sa distance d'avancement à l'intérieur de la zone de fermeture, est réglé dans le mode de réalisation de l'invention présenté sur les Figs. par un ensemble de butée 220, chaque butée 220 étant disposée en amont de la courroie de transfert 208 et en aval de la table de reliure 216 et du guide supérieur 210. Chaque butée 220 prend ici la forme d'une aiguille verticale qui est mobile verticalement entre une position de repos et une position d'activation. Dans la position d'activation, les butées 220 pénètrent dans la zone de fermeture et servent de butée au paquet de feuilles perforées 204 lors de son introduction pour que celui-ci soit correctement positionné par rapport aux éléments de reliure 206. Dans la position de repos, les butées 220 sont escamotées et ne sont donc pas présentes dans la zone de fermeture. En fonction du type de paquets de feuilles perforées 204 à relier et des éléments de reliure 206 utilisés, il est possible que seules certaines butées 220 soient nécessaires. A cette fin, chaque butée 220 est mobile individuellement et peut donc être actionnée de manière indépendante des autres butées 220. Par exemple, chaque butée 220 est actionnée par un actionneur pneumatique indépendant, et chaque actionneur est activé par l'unité centrale qui gère les différents composants électroniques de la machine à relier 100. Par exemple, il est possible de désactiver les butées 220 centrales dans le cas où un crochet du type crochet de calendrier est prévu.The deep positioning of the packet of
Comme cela est expliqué ci-après, la mâchoire de fermeture supérieure 214 est mobile verticalement, et à cette fin, des moyens d'actionnement, ici un moteur 224, sont prévus pour monter et descendre la mâchoire de fermeture supérieure 214 à travers une cinématique appropriée.As explained below, the
De la même manière, la mâchoire de fermeture inférieure 218 est mobile verticalement, et à cette fin, la machine à relier 100 comprend des moyens de réglage prévus pour régler verticalement la position de la mâchoire de fermeture inférieure 218. Ici, les moyens de réglage sont constitués d'un moteur 226 et d'une cinématique appropriée.In the same way, the

La table de reliure 216 et le guide supérieur 210 sont de préférence réalisés en plaques métalliques à l'intérieur desquelles sont disposées des barrettes d'aimants référencées respectivement 212 et 304.The binding table 216 and the
De la même manière, la courroie de transfert 208 glisse devant une paroi métallique 306 qui est rendue magnétique par mise en place d'une barrette d'aimants 302 à l'arrière de ladite paroi métallique 306.In the same way, the
Chaque barrette d'aimants 212, 304, 302 court sur la longueur de la plaque métallique 210, 216, 306 qui la porte c'est-à-dire perpendiculairement à la direction d'introduction du paquet de feuilles perforées 204.Each

Sur la
Pour maintenir les éléments de reliure 206, la courroie de transfert 208 comporte des nervures verticales distantes les unes des autres. La distance entre les nervures est telle qu'une nervure vient s'insérer dans un espace libre entre deux pointes 604 successives. Les positions des nervures sont telles que tous types d'éléments de reliure 206 peuvent être ainsi maintenus.To maintain the
Pour que la courroie de transfert 208 puisse maintenir les éléments de reliure 206 de tous diamètres, la barrette d'aimants 302 est disposée au voisinage de la partie basse de la courroie de transfert 208. Ainsi, le positionnement des éléments de reliure 206 est réglé par la position de la barrette d'aimants 302 et par la mâchoire de fermeture inférieure 218 sur laquelle les éléments de reliure 206 reposent.In order for the
Sur la
Les butées 220 sont en position de repos, c'est-à-dire qu'elles sont escamotées pour ne pas pénétrer dans la zone de fermeture et pour ne pas gêner la progression des éléments de reliure 206 lors de leur déplacement vers la position d'engagement.The
La mâchoire de fermeture inférieure 218 est ici constituée d'une plaque horizontale et est disposée au voisinage de la courroie de transfert 208, de manière à ce que les éléments de reliure 206 qui sont maintenus par la courroie de transfert 208 reposent sur la mâchoire de fermeture inférieure 218 par l'intermédiaire des zones arrondies portant les bases 602. La mâchoire de fermeture inférieure 218 est positionnée de manière à ce que les extrémités des éléments de reliure 206 qui portent les bases 602 se positionnent légèrement en dessous du plan de la table de reliure 216, évitant ainsi lors de la mise en place du paquet de feuilles perforées 204, une interaction entre le bord du paquet 204 et lesdites extrémités.The

La position des butées 220 est adaptée de manière à ce que lors du passage en position d'activation, elles ne viennent pas heurter les éléments de reliure 206 mais les traversent dans les zones entre les doigts.The position of the

D'une manière générale, la courroie de transfert 208 comprend des premiers moyens 302 pour générer un champ magnétique, la table de reliure 216 comprend des deuxièmes moyens 304 pour générer un champ magnétique et le guide supérieur 210 comprend des troisièmes moyens 212 pour générer un champ magnétique. Dans la zone de fermeture, le champ magnétique résultant généré par les deuxièmes moyens 304 et les troisièmes moyens 212 sur les éléments de reliure 206 est supérieur au champ magnétique généré par les premiers moyens 302.In general, the
Après les retraits de la courroie de transfert 208 et des butées 220, la mâchoire de fermeture supérieure 214 est abaissée pour venir en contact avec les éléments de reliure 206, et en particulier avec les zones arrondies portant les pointes 604. L'abaissement de la mâchoire de fermeture supérieure 214 s'effectue par un déplacement vertical de haut en bas. La mâchoire de fermeture supérieure 214 poursuit alors sa descente de manière à fermer les éléments de reliure 206 en les écrasant et en leur donnant une forme annulaire par rapprochement des pointes 604 au voisinage des bases 602.After the withdrawals of the

A cette fin, la machine à relier comprend des moyens de réglage prévus pour régler verticalement la position du guide supérieur 210.To this end, the binding machine comprises adjustment means provided for vertically adjusting the position of the
La zone de fixation du guide supérieur 210 et la zone de fixation de la table de reliure 216, au niveau desquelles les extrémités des éléments de reliure 206 se fixent, présentent chacune un chanfrein 502, 504 de sensiblement 45° sur 1,5 mm. Ces chanfreins 502 et 504 permettent d'orienter les extrémités des éléments de reliure 206 lors de leur fermeture par la mâchoire de fermeture supérieure 214, ce qui permet d'obtenir une forme annulaire dont le profil est pratiquement circulaire. Les chanfreins 502 et 504 évitent que lors de la fermeture des éléments de reliure 206, les extrémités 602 et 604 de ces derniers butent contre les flancs verticaux du guide supérieur 210 et de la table de reliure 216 et se tordent sans se fermer.The attachment area of the

Lorsque des butées 220 équipent la machine à relier 100, le procédé de reliure comprend, entre l'étape de déplacement de la courroie de transfert 208 vers la position d'engagement et l'étape d'insertion du paquet de feuilles perforées 204, une étape de déplacement des butées 220 sélectionnées vers la position d'activation, et entre l'étape d'insertion du paquet de feuilles perforées 204 et l'étape de fermeture des éléments de reliure 206, une étape de déplacement des butées 220 de la position d'activation vers la position de repos.When stops 220 equip the

Dans le cas où les éléments de fermeture sont constitués de la mâchoire de fermeture inférieure 218 et de la mâchoire de fermeture supérieure 214, l'étape de fermeture des éléments de reliure 206 consiste en une étape d'écrasement des éléments de reliure 206 entre lesdites mâchoires 214 et 218 par déplacement vertical de la mâchoire de fermeture supérieure 214.In the case where the closure elements consist of the
Cette étape d'écrasement est suivie par une étape de soulèvement de la mâchoire de fermeture supérieure 214 hors de la zone de fermeture préalablement à la mise en oeuvre de l'étape de déplacement de la courroie de transfert 208 vers la position de dégagement suivante.This crushing step is followed by a step of lifting the

Le procédé de reliure comprend également une phase d'initialisation qui est effectuée préalablement à la première étape de fourniture d'éléments de reliure 206. Le technicien renseigne, par exemple, le diamètre, le nombre et la répartition des éléments de reliure 206 et l'unité centrale commande la mise en oeuvre de la phase d'initialisation au cours de laquelle les différents composants de la machine à relier 100 sont réglés en fonction de ces caractéristiques.The binding method also comprises an initialization phase which is carried out prior to the first step of supplying
La phase d'initialisation comprend entre autre:
- une étape de réglage de la position verticale de la mâchoire de fermeture inférieure 218 en fonction du diamètre des éléments de reliure 206 par actionnement du moteur 226 et ceci afin de garantir la distance verticale entre le plan de la table de reliure 216 et le plan de la mâchoire de fermeture inférieure 218,
