TÊTE PORTE-OUTIL. CHARIOT DE TRANSPORT ET PROCEDES DE MONTAGE ET DE DEMONTAGE D'OUTIL POUR GROUPE DE TRANSFORMATION D'UN  HEAD TOOL HOLDER. TRANSPORT TROLLEY AND METHODS FOR MOUNTING AND DISASSEMBLING TOOL FOR A TRANSFORMER UNIT
SUPPORT PLAN  SUPPORT PLAN
La présente invention concerne une tête porte-outil, destinée à un chariot de transport d'outils rotatifs, pour un groupe de transformation d'un support plan. L'invention concerne un chariot de transport, muni d'une tête porte-outil pour un groupe de transformation d'un support plan. L'invention se rapporte également à un procédé de montage d'outil dans un groupe de transformation d'un support plan, et un procédé de démontage d'outil dans un groupe de transformation d'un support plan. The present invention relates to a tool head, intended for a carriage for transporting rotating tools, for a processing group of a plane support. The invention relates to a transport carriage, provided with a tool head for a processing unit of a plane support. The invention also relates to a tool mounting method in a planar support processing group, and a tool dismantling method in a planar support processing group.
Une machine de transformation de support est destinée à la fabrication d'emballages. Dans cette machine, un support plan initial, tel qu'une bande continue de carton, est déroulé et imprimé par une station d'impression comprenant un ou plusieurs groupes imprimeurs. Le support plan est ensuite transféré dans un groupe d'introduction, puis dans un groupe de gaufrage, éventuellement suivi par un groupe de refoulage. Le support plan est ensuite découpé dans un groupe de découpe. Après éjection des zones de déchets, les poses obtenues sont sectionnées pour obtenir des boîtes individualisées. A support processing machine is intended for the manufacture of packaging. In this machine, an initial planar support, such as a continuous strip of cardboard, is unwound and printed by a printing station comprising one or more printing units. The planar support is then transferred to an introductory group and then to an embossing group, possibly followed by a push-up group. The flat support is then cut in a cutting group. After ejection of the waste zones, the obtained poses are cut to obtain individualized boxes.
Les groupes rotatifs de transformation, de gaufrage, refoulage, découpe, éjection des déchets, ou imprimeur, comportent respectivement un outil supérieur cylindrique de transformation, et un outil inférieur cylindrique de transformation, entre lesquels circule le support plan pour être transformé. En fonctionnement, les outils rotatifs de transformation tournent à la même vitesse, mais en sens inverse l'un de l'autre. Le support plan passe dans l'interstice situé entre les outils rotatifs, qui façonnent un relief par gaufrage, façonnent un relief par refoulage, découpent le support plan en poses en découpe rotative, éjectent les déchets, ou qui impriment un motif lors de l'impression.  The rotary groups of transformation, embossing, crushing, cutting, ejection of waste, or printer comprise respectively an upper cylindrical tool for processing, and a lower cylindrical tool for transformation, between which the plane support circulates to be transformed. In operation, the rotary transformation tools rotate at the same speed, but in opposite directions from each other. The plane support passes into the gap between the rotary tools, which shape an embossed relief, shape a raised relief, cut the plane support into poses in a rotary cut, eject the waste, or print a pattern during the process. impression.
Les opérations de changement de cylindres s'avèrent longues et fastidieuses. L'opérateur déconnecte mécaniquement le cylindre pour l'enlever de son mécanisme d'entraînement. Puis l'opérateur sort le cylindre en dehors de la machine de transformation, et replace le nouveau cylindre dans la machine de transformation en le reconnectant à son entraînement. Le poids d'un cylindre est important, de l'ordre de 50 kg à 2Ό00 kg. Pour le sortir, l'opérateur le soulève à l'aide d'un palan.  Cylinder change operations are long and tedious. The operator mechanically disconnects the cylinder to remove it from its drive mechanism. Then the operator pulls the cylinder outside the processing machine, and puts the new cylinder back into the processing machine by reconnecting it to its drive. The weight of a cylinder is important, of the order of 50 kg to 2Ό00 kg. To pull it out, the operator raises it with a hoist.
En raison de son poids assez élevé, un changement de cylindre n'est pas très rapide à effectuer. En outre, de nombreux changements d'outils peuvent être nécessaires pour obtenir de très nombreuses boîtes différentes les unes des autres. Ces outils doivent être commandés longtemps à l'avance, ce qui devient incompatible avec les changements de productions demandés actuellement. De plus, des outils sont relativement coûteux à réaliser, et ils ne deviennent rentables qu'avec une production extrêmement importante. Because of its rather high weight, a cylinder change is not very quick to perform. In addition, many tool changes can be necessary to obtain many different boxes from each other. These tools must be ordered well in advance, which becomes incompatible with the changes in production currently required. In addition, tools are relatively expensive to produce, and they only become profitable with extremely high production.
Ainsi certains groupes de transformation prévoient l'utilisation d'outils rotatifs composés d'un mandrin et d'un manchon amovible porteur de forme assurant la transformation, insérable sur le mandrin. Il suffit alors de changer le manchon, plutôt que la totalité de l'outil rotatif. Ceci facilite le changement d'outil du fait du faible poids du manchon et diminue les coûts, car le manchon est moins onéreux. Le mandrin peut également être aussi changé et est choisi en fonction de son diamètre.  Thus, some processing groups provide for the use of rotary tools consisting of a mandrel and a removable sleeve carrying shape ensuring the transformation, insertable on the mandrel. Then simply change the sleeve, rather than the entire rotary tool. This facilitates the tool change due to the low weight of the sleeve and reduces costs because the sleeve is less expensive. The mandrel can also be changed and is chosen according to its diameter.
Cependant, les opérations de chargement et d'échange des outils rotatifs dans les groupes de transformation, restent délicates pour les opérateurs, en raison notamment des précisions de montage exigées dans le groupe et du poids important de ces outils. Ainsi, les producteurs d'emballage cherchent aujourd'hui à faciliter la manipulation des outils rotatifs vers ou à l'écart des groupes de transformation, de manière que ceux-ci puissent être changés rapidement, de façon reproductible et de manière simple. Exposé de l'invention  However, the loading and exchange of rotary tools in the processing groups, remain delicate for operators, due in particular to the assembly specifications required in the group and the weight of these tools. Thus, packaging producers are now seeking to facilitate the handling of rotating tools to or away from processing groups, so that they can be changed quickly, reproducibly and in a simple manner. Presentation of the invention
Un but de la présente invention est de proposer des dispositifs et procédés qui résolvent au moins en partie les inconvénients de l'état de la technique.  An object of the present invention is to provide devices and methods which at least partly solve the disadvantages of the state of the art.
A cet effet, l'invention a pour objet une tête porte-outil pour un chariot de transport d'outils rotatifs de groupe de transformation d'un support plan. La tête porte- outil comprend un port supérieur et un port inférieur. Le port supérieur et le port inférieur sont agencés l'un au-dessus de l'autre, et sont destinés à recevoir respectivement une extrémité avant d'un outil rotatif supérieur et une extrémité avant d'un outil rotatif inférieur. For this purpose, the subject of the invention is a tool head for a carriage for rotating tools of transformation group of a plane support. The tool head includes an upper port and a lower port. The upper port and the lower port are arranged one above the other, and are intended to respectively receive a front end of an upper rotary tool and a front end of a lower rotary tool.
L'invention a également pour objet une tête porte-outil pour chariot de transport d'outils rotatifs de groupe de transformation d'un support plan. Le chariot de transport est équipé d'une base mobile. La tête porte-outil comprend au moins un port, destiné à recevoir une extrémité avant d'un outil rotatif, et positionné en porte-à faux par rapport à la base mobile, de façon à pouvoir faire pénétrer l'outil rotatif à l'intérieur du groupe de transformation. Un outil est défini comme étant un mandrin, un ensemble mandrin avec manchon, un outil d'un seul tenant, ou d'autres encore. Le groupe de transformation est défini comme étant un groupe de refoulage, un groupe de gaufrage, un groupe de découpe rotative, un groupe d'éjection des déchets, un groupe imprimeur, choisi seul ou en combinaison, ou d'autres encore. The subject of the invention is also a tool head for a transport trolley for rotating tools of a processing group of a plane support. The transport trolley is equipped with a mobile base. The tool head comprises at least one port for receiving a front end of a rotary tool and positioned cantilevered with respect to the movable base so that the rotary tool can be inserted into the tool. inside the transformation group. A tool is defined as a mandrel, a chuck assembly with a sleeve, an integral tool, or others. The transformation group is defined as a push-back group, an embossing group, a rotary cutting group, a waste ejection group, a printing unit, chosen alone or in combination, or others.
L'agencement des outils parallèles selon un écartement prédéterminé dans le chariot de transport permet leur transfert sans manipulations supplémentaires des outils rotatifs déjà pré-positionnés au niveau des paliers du groupe de transformation. La tête porte-outil permet ainsi d'agencer le ou les outils rotatifs, de façon à ce qu'il puisse être facilement monté/démonté dans le groupe de transformation. Ainsi les risques de collision entre les outils rotatifs mais aussi entre les outils rotatifs et le groupe de transformation sont diminués. Le positionnement des outils rotatifs est également facilité dans l'axe des paliers du groupe de transformation. Par ailleurs, le nombre d'opérations est réduit et la manutention des outils rotatifs, lourds, est facilitée.  The arrangement of the parallel tools at a predetermined spacing in the transport carriage allows their transfer without additional manipulations of the rotary tools already pre-positioned at the bearings of the transformation group. The tool head thus makes it possible to arrange the rotary tool or tools, so that it can be easily mounted / disassembled in the transformation unit. Thus the risk of collision between the rotary tools but also between the rotary tools and the transformation group are reduced. The positioning of the rotary tools is also facilitated in the axis of the bearings of the transformation group. In addition, the number of operations is reduced and the handling of heavy rotary tools is facilitated.
Selon un exemple de réalisation, la tête porte-outil comporte une interface de maintien, destinée à coopérer avec une tourelle du groupe de transformation, pour fixer la tête porte-outil à la tourelle. La fixation du chariot de transport au groupe de transformation permet que ce soit le groupe de transformation qui référence le positionnement précis des outils rotatifs.  According to an exemplary embodiment, the tool head comprises a holding interface, intended to cooperate with a turret of the transformation unit, for fixing the tool head to the turret. Attaching the transport trolley to the transformation unit allows the transformation group to refer to the precise positioning of the rotary tools.
L'interface de maintien est par exemple configurée pour suspendre la tête porte- outil à la tourelle du groupe de transformation. La fixation de la tête porte-outil par suspension à la tourelle est ergonomique, notamment grâce à l'utilisation d'un dispositif élévateur du chariot de transport, configuré pour monter ou descendre la tête porte- outil par rapport à la base mobile du chariot de transport.  The holding interface is for example configured to suspend the tool head to the turret of the transformation group. The fixing of the tool head by suspension to the turret is ergonomic, in particular through the use of an elevator device of the transport carriage, configured to raise or lower the tool head relative to the mobile base of the carriage transport.
Par exemple, l'interface de maintien comporte au moins un premier organe d'accroché destiné à coopérer avec au moins un premier organe d'accroché complémentaire de la tourelle. Les premiers organes d'accroché permettent le guidage et la fixation de la tête porte-outil au groupe de transformation, notamment en évitant les mouvements de la tête porte-outil dans la direction transversale, dans l'axe de rotation des outils rotatifs.  For example, the holding interface comprises at least a first hook member intended to cooperate with at least one first hook member complementary to the turret. The first hooking members allow guiding and fixing of the tool head to the transformation unit, in particular by avoiding movements of the tool head in the transverse direction, in the axis of rotation of the rotary tools.
Les premiers organes d'accroché comportent par exemple au moins un premier crochet, apte à coopérer avec un premier galet monté libre en rotation. Les galets permettent de faciliter le montage et le démontage de la tête porte-outil sur la tourelle, en limitant les risques de coincements. Par exemple, l'interface de maintien comporte au moins un premier épaulement destiné à coopérer avec une cale de soutien de la tourelle pour porter la tête porte- outil, de manière que lorsque la tête porte-outil est portée par la cale de soutien, les premiers crochets soient sensiblement disposés au-dessus des premiers galets. Cela permet que la tête porte-outil ne repose pas sur les premiers galets mais que l'essentiel du poids des outils rotatifs soit repris par les cales de soutien de la tourelle. Les cales de soutien permettent ainsi de soulager les premiers galets du poids des outils rotatifs sensiblement plus fragiles. Les butées de soutien, fixées à la tourelle, forment la référence verticale. The first hook members comprise for example at least one first hook, adapted to cooperate with a first roller mounted free to rotate. The rollers facilitate the assembly and disassembly of the tool head on the turret, limiting the risk of jamming. For example, the holding interface comprises at least a first shoulder intended to cooperate with a support wedge of the turret for carrying the tool head, so that when the tool head is carried by the support wedge, the first hooks are substantially arranged above the first rollers. This allows the tool head does not rest on the first rollers but most of the weight of the rotary tools is taken up by the support wedges of the turret. The support wedges thus make it possible to relieve the first rollers of the weight of rotary tools that are substantially more fragile. The support stops, attached to the turret, form the vertical reference.
Par exemple, l'interface de maintien comporte au moins une lumière de guidage, destinée à coopérer avec un pion de guidage complémentaire porté par la tourelle, la lumière de guidage présentant une forme en L d'épaisseur plus fine que les ouvertures des premiers crochets. La lumière et le pion de guidage permettent de guider l'accostage de la tête porte-outil sur la tourelle. Le pion de guidage plus robuste que les galets permet ainsi le guidage de la tête porte-outil dans la direction dans l'axe de rotation des outils rotatifs puis, verticalement, en suivant la trajectoire en forme de L des lumières de guidage, en évitant d'éventuelles collisions entre le ou les crochets du porte-outil et les galets de la tourelle.  For example, the holding interface comprises at least one guiding light, intended to cooperate with a complementary guiding pin carried by the turret, the guiding light having a L-shaped thickness thinner than the openings of the first hooks . The light and the guide pin guide the docking of the tool head on the turret. The guide pin is more robust than the rollers and thus allows the guide head to be guided in the direction in the axis of rotation of the rotary tools and then, vertically, along the L-shaped path of the guide lights, avoiding possible collisions between the tool holder hook (s) and the turret rollers.
Selon un exemple de réalisation, la tête porte-outil comporte une deuxième interface avant de maintien, destinée à coopérer avec une base mobile du chariot de transport, pour fixer la tête porte-outil à la base mobile. La tête porte-outil est alors amovible, de sorte que la base mobile peut être commune pour différentes têtes porte- outil.  According to an exemplary embodiment, the tool head comprises a second front holding interface, intended to cooperate with a mobile base of the transport carriage, for fixing the tool head to the mobile base. The tool head is then removable, so that the movable base can be common for different tool heads.
Par exemple, la deuxième interface de maintien est configurée pour suspendre la tête porte-outil à la base mobile.  For example, the second holding interface is configured to suspend the tool head at the mobile base.
Par exemple, la deuxième interface de maintien comporte au moins un second organe d'accroché, destiné à coopérer avec au moins un second organe d'accroché complémentaire de la base mobile, les seconds organes d'accroché comportant au moins un second crochet, apte à coopérer avec un second galet monté libre en rotation. Les galets permettent de faciliter le montage et le démontage de la tête porte- outil sur la base mobile, en limitant les risques de coincements.  For example, the second holding interface comprises at least a second hook member, intended to cooperate with at least one second hook member complementary to the mobile base, the second hook members comprising at least a second hook, suitable to cooperate with a second roller mounted free to rotate. The rollers facilitate the assembly and disassembly of the tool head on the mobile base, limiting the risk of jamming.
Par exemple, la deuxième interface de maintien comporte au moins un deuxième épaulement destiné à coopérer avec une cale de soutien de la base mobile pour porter la tête porte-outil, de manière que lorsque la tête porte-outil est portée par la cale de soutien, les seconds crochets soient sensiblement disposés au-dessus des seconds galets. Selon un exemple de réalisation, la tête porte-outil comporte un dispositif de verrouillage configuré pour prendre une position déverrouillée ou une position de verrouillage, dans laquelle le dispositif de verrouillage verrouille le maintien de l'extrémité avant de l'outil dans les ports supérieur et inférieur. For example, the second holding interface comprises at least one second shoulder intended to cooperate with a support wedge of the mobile base to carry the tool head, so that when the tool head is carried by the support wedge the second hooks are substantially disposed above the second rollers. According to an exemplary embodiment, the tool head comprises a locking device configured to take an unlocked position or a locking position, in which the locking device locks the maintenance of the front end of the tool in the upper ports. and lower.
Selon un exemple de réalisation, le dispositif de verrouillage comporte un système articulé, un pion de verrouillage supérieur, un pion de verrouillage inférieur et un levier d'actionnement raccordé aux pions de verrouillage supérieur et inférieur par le système articulé de sorte que l'actionnement du levier positionne les pions de verrouillage en position déverrouillée ou de verrouillage.  According to an exemplary embodiment, the locking device comprises an articulated system, an upper locking pin, a lower locking pin and an actuating lever connected to the upper and lower locking pins by the articulated system so that the actuation the lever positions the locking pins in the unlocked or lock position.
Selon un exemple de réalisation, les ports supérieur et inférieur comportent un dispositif élastique respectif, destiné à venir en appui contre l'extrémité avant de l'outil et pouvant être repoussé par celui-ci vers le fond du logement du port supérieur ou inférieur. Les collisions des outils sont ainsi évitées avec la tête porte-outil en position déverrouillée par manipulation des outils aux extrémités arrière par la pince des moyens d'entraînement motorisés, côté opposé conducteur. L'extrémité arrière de l'outil est au fond de la pince des moyens d'entraînement.  According to an exemplary embodiment, the upper and lower ports comprise a respective elastic device, intended to abut against the front end of the tool and can be pushed by it towards the bottom of the housing of the upper or lower port. The collisions of the tools are thus avoided with the tool head in the unlocked position by manipulation of the tools at the rear ends by the gripper motorized drive means, opposite side driver. The rear end of the tool is at the bottom of the clamp drive means.
L'invention a aussi pour objet un chariot de transport comportant un pied muni d'éléments roulants caractérisé en ce qu'il comporte une tête porte-outil telle que décrite et revendiquée ci-dessous, et un dispositif élévateur configuré pour monter ou descendre la tête porte-outil par rapport au pied. Le dispositif élévateur permet ainsi de lever et descendre des charges importantes telles que les éléments d'outils rotatifs pour suspendre la tête porte-outil sur la tourelle du groupe de transformation mais permet aussi de rendre la manutention du chariot de transport en usine plus sûre en abaissant le centre de gravité de la charge. En effet, l'abaissement des charges lors du convoyage des outils rotatifs dans l'usine permet d'éviter que le chariot de transport ne soit déséquilibré par les outils rotatifs en porte-à-faux.  The invention also relates to a transport carriage comprising a foot provided with rolling elements characterized in that it comprises a tool head as described and claimed below, and a lifting device configured to raise or lower the tool head relative to the foot. The lifting device thus makes it possible to raise and lower important loads such as the rotary tool elements for suspending the tool head on the turret of the processing unit but also makes it possible to make the handling of the transport trolley in the factory safer in operation. lowering the center of gravity of the load. Indeed, the lowering of the loads during the conveying of the rotary tools in the factory makes it possible to avoid that the transport trolley is unbalanced by the cantilever rotary tools.

Le groupe de transformation 7 comprend un outil rotatif supérieur 10 et un outil rotatif inférieur 11 , qui modifient le support plan par impression, gaufrage, refoulage, découpe, éjection des déchets, etc., en vue d'obtenir un emballage.  The transformation unit 7 comprises an upper rotary tool 10 and a lower rotary tool 11, which modify the plane support by printing, embossing, crushing, cutting, ejection of waste, etc., in order to obtain a package.
Les outils rotatifs 10 et 11 , sont montés parallèlement l'un par rapport à l'autre dans le groupe de transformation 7, l'un au-dessus de l'autre, et s'étendent selon la direction transversale T, qui est aussi la direction des axes de rotation A1 et A2 des outils rotatifs 10 et 11 (voir Fig. 2). Les extrémités arrière 10b et 11 b des outils rotatifs 10 et 11 , côté opposé conducteur, sont entraînées en rotation par des moyens d'entraînement motorisés (non représentés).  The rotary tools 10 and 11, are mounted parallel to each other in the transformation group 7, one above the other, and extend in the transverse direction T, which is also the direction of the axes of rotation A1 and A2 of the rotary tools 10 and 11 (see Fig. 2). The rear ends 10b and 11b of the rotary tools 10 and 11, the opposite side conductive, are rotated by motorized drive means (not shown).
En fonctionnement, les outils rotatifs 10 et 11 tournent dans des sens opposés autour d'un axe de rotation A1 et A2 respectif (Flèches Fs et Fi sur la Fig. 2). Le support plan passe dans l'interstice situé entre les outils rotatifs 10 et 11 , pour y être gaufré, et/ou refoulé, et/ou découpé, et/ou imprimé.  In operation, the rotary tools 10 and 11 rotate in opposite directions around a respective axis of rotation A1 and A2 (arrows Fs and Fi in Fig. 2). The plane support passes into the gap between the rotary tools 10 and 11, to be embossed, and / or discharged, and / or cut, and / or printed.
Les outils rotatifs, l'outil rotatif supérieur 10 ou l'outil rotatif inférieur 11 , comportent respectivement un mandrin 12 et un manchon amovible 13, insérable sur le mandrin 12 dans la direction transversale T (Fig. 2, Flèche G). Ainsi, lorsqu'un opérateur souhaite changer les outils rotatifs 10 et 11 , il suffit de changer les manchons 13 plutôt que la totalité de l'outil rotatif 10 et 11 . La manipulation du manchon 13 étant facilitée par son faible poids relativement à celui de l'outil rotatif 10 et 11 complet, le changement de travail peut être effectué rapidement. En outre, les manchons 13 sont peu coûteux comparés au prix de l'outil rotatif 10 et 11 complet. Il est donc avantageux d'utiliser un même mandrin 12 en combinaison avec plusieurs manchons 13, plutôt que de prévoir l'acquisition de plusieurs outils rotatifs 10 et 11 complets. The rotary tools, the upper rotary tool 10 or the lower rotary tool 11 respectively comprise a mandrel 12 and a removable sleeve 13, insertable on the mandrel 12 in the transverse direction T (FIG 2, arrow G). Thus, when an operator wishes to change the rotary tools 10 and 11, it suffices to change the sleeves 13 rather than the entire rotary tool 10 and 11. The manipulation of the sleeve 13 being facilitated by its low weight relative to that of the rotary tool 10 and 11 complete, the Job change can be done quickly. In addition, the sleeves 13 are inexpensive compared to the price of the rotary tool 10 and 11 complete. It is therefore advantageous to use the same mandrel 12 in combination with several sleeves 13, rather than to provide the acquisition of several rotary tools 10 and 11 complete.
Le manchon 13 présente une forme générale cylindrique. Le mandrin 12 et le manchon 13 sont en matériau métallique, le mandrin 12 est par exemple en acier et le manchon 13 en aluminium. Les extrémités avant et arrière 10a, 11 a, 10b, 11 b des mandrins 12 (ou tourillons), forment les extrémités des outils rotatifs 10 et 11 destinés à coopérer avec des paliers avant et arrière du groupe de transformation 7.  The sleeve 13 has a generally cylindrical shape. The mandrel 12 and the sleeve 13 are made of metallic material, the mandrel 12 is for example made of steel and the sleeve 13 is of aluminum. The front and rear ends 10a, 11a, 10b, 11b of the mandrels 12 (or pins) form the ends of the rotary tools 10 and 11 intended to cooperate with front and rear bearings of the transformation unit 7.
Les paliers avant et arrière sont respectivement portés par un montant porte-outil The front and rear bearings are respectively carried by a tool holder
16 agencé à l'avant du bâti, également appelé tourelle et un montant porte-outil agencé à l'arrière du bâti. La tourelle 16 s'étend verticalement et présente une forme de cadre avec un passage central pour les outils rotatifs 10 et 11 . 16 arranged at the front of the frame, also called turret and a tool holder arranged at the rear of the frame. The turret 16 extends vertically and has a frame shape with a central passage for the rotary tools 10 and 11.
Une fois montés dans le groupe de transformation 7, les outils rotatifs 10 et 11 , sont parallèles l'un par rapport à l'autre. Les outils rotatifs 10 et 11 sont l'un au-dessus de l'autre, et s'étendent selon la direction transversale T, qui est aussi la direction des axes de rotation A1 et A2 des outils rotatifs 10 et 11 (voir Fig. 2).  Once mounted in the transformation group 7, the rotary tools 10 and 11 are parallel to each other. The rotary tools 10 and 11 are one above the other, and extend in the transverse direction T, which is also the direction of the axes of rotation A1 and A2 of the rotary tools 10 and 11 (see FIG. 2).
Un chariot de transport 20 (Figs. 3 à 5) est prévu pour le montage, le démontage du mandrin 12 ou de l'outil rotatif 10 et 11 complets, dans ou hors du groupe de transformation 7, ainsi que pour leur transport.  A transport carriage 20 (Figs 3 to 5) is provided for mounting or dismounting the complete mandrel 12 or rotary tool 10 and 11 in or out of the processing unit 7 as well as for transporting them.
Le chariot de transport 20 comporte une tête porte-outil 21 et une base mobile 22. La base mobile 22 comporte un tronc 23 terminé par un pied 24 muni d'éléments roulants 25. Le pied 24 s'étend dans la direction d'avance du chariot de transport 20. Les éléments roulants 25 sont par exemple des roues, les roues arrière étant par exemple montées sur pivot. Le tronc 23 comporte également un moyen de préhension 28, agencé à l'arrière, pour pousser, tirer, guider manuellement le déplacement du chariot de transport 20 dans l'usine.  The transport carriage 20 comprises a tool head 21 and a mobile base 22. The mobile base 22 comprises a trunk 23 terminated by a foot 24 provided with rolling elements 25. The foot 24 extends in the direction of advance of the transport carriage 20. The rolling elements 25 are for example wheels, the rear wheels being for example pivotally mounted. The trunk 23 also comprises a gripping means 28, arranged at the rear, to push, pull, manually guide the movement of the transport carriage 20 in the factory.
La tête porte-outil 21 est munie d'un port supérieur 29 et d'un port inférieur 30 destinés à recevoir une extrémité d'outil 12 respective. L'extrémité d'outil est soit celle d'un mandrin 12 seul, soit celle d'un mandrin 12 pourvu d'un manchon 13, c'est-à-dire celle d'un outil rotatif 10 et 11 complet, soit celle d'un outil d'un seul tenant.  The tool head 21 is provided with an upper port 29 and a lower port 30 for receiving a respective tool end 12. The tool end is either that of a mandrel 12 alone, or that of a mandrel 12 provided with a sleeve 13, that is to say that of a rotary tool 10 and 11 complete, or that a tool in one piece.
Les ports supérieur et inférieur 29 et 30 de la tête porte-outil 21 sont identiques. Ils sont agencés l'un au-dessus de l'autre. Une fois montés dans la tête porte-outil 21 , les mandrins 12 ou outils rotatifs 10 et 11 s'étendent parallèlement et restant maintenus espacés d'un écartement prédéterminé. Ils font saillie de la tête porte-outil 21 dans la direction d'avance du chariot de transport 20. La tête porte-outil 21 permet ainsi d'agencer les outils rotatifs 10 et 11 de manière que ceux-ci puissent être facilement montés/démontés dans le groupe de transformation 7. Leur agencement parallèle selon un écartement prédéterminé dans le chariot de transport 20 permet leur transfert sans manipulations supplémentaires des outils rotatifs 10 et 11 déjà pré-positionnés au niveau des paliers du groupe de transformation 7. Les risques de collision entre les outils rotatifs 10 et 11 sont ainsi diminués, mais aussi entre les outils rotatifs 10 et 11 et le groupe de transformation 7. le positionnement des outils rotatifs 10 et 11 est également facilité dans l'axe des paliers du groupe de transformation 7. Par ailleurs, le nombre d'opérations est réduit et la manutention des outils rotatifs 10 et 11 , lourds, est facilitée. The upper and lower ports 29 and 30 of the tool head 21 are identical. They are arranged one above the other. Once mounted in the tool head 21, the chucks 12 or rotary tools 10 and 11 extend parallel and remain held spaced apart by a predetermined spacing. They protrude from the tool head 21 in the direction of advance of the transport carriage 20. The tool head 21 thus makes it possible to arrange the rotary tools 10 and 11 in such a way that they can be easily mounted / disassembled in the transformation unit 7. Their parallel arrangement according to a predetermined spacing in the transport carriage 20 allows their transfer without additional manipulations of the rotary tools 10 and 11 already pre-positioned at the bearings of the transformation unit 7. The risks of collision between the rotary tools 10 and 11 are thus reduced, but also between the rotary tools 10 and 11 and the transformation group 7. the positioning of the rotary tools 10 and 11 is also facilitated in the axis of the bearings of the transformation unit 7. Moreover, the number of operations is reduced and the handling of the rotary tools 10 and 11, heavy , is facilitated.
Pour l'accostage de la tête porte-outil 21 au groupe de transformation 7, la tête porte-outil 21 peut comporter une interface frontale de maintien, destinée à coopérer avec la tourelle 16 du groupe de transformation 7, pour fixer la tête porte-outil 21 à la tourelle 16. La fixation du chariot de transport 20 au groupe de transformation 7 permet que ce soit le groupe de transformation 7 qui référence le positionnement précis du mandrin 12 ou de l'outil.  For the docking of the tool head 21 to the processing unit 7, the tool-holding head 21 may comprise a front-end interface intended to cooperate with the turret 16 of the transformation unit 7, in order to fix the head-carrier Tool 21 at the turret 16. Attaching the transport carriage 20 to the transformation unit 7 allows it to be the transformation group 7 which refers to the precise positioning of the mandrel 12 or the tool.
Selon un exemple de réalisation représenté sur les Figs. 3 à 11 , l'interface frontale de maintien est configurée pour suspendre la tête porte-outil 21 à la tourelle 16 du groupe de transformation 7. La fixation de la tête porte-outil 21 par suspension à la tourelle 16 est facile à réaliser et peut en outre être entièrement rendue automatique, notamment grâce à l'utilisation d'un dispositif élévateur du chariot de transport 20, configuré pour monter (Figs. 3 et 4) ou descendre (Fig. 5) la tête porte-outil 21 par rapport au pied 24.  According to an exemplary embodiment shown in FIGS. 3 to 11, the front holding interface is configured to suspend the tool head 21 to the turret 16 of the transformation unit 7. The attachment of the tool head 21 by suspension to the turret 16 is easy to perform and It can also be made fully automatic, in particular by the use of an elevator device of the transport trolley 20, configured to mount (Figs 3 and 4) or to lower (Fig. 5) the tool head 21 relative to at the foot 24.
Selon un exemple de réalisation, le dispositif élévateur comporte un actionneur, tel qu'un vérin hydraulique 31 actionnable par un levier 32. Le dispositif élévateur peut également comporter deux rails de guidage 33, agencés verticalement dans le tronc 23 de la base mobile 22, de part et d'autre de la tête porte-outil 21 , pour guider le déplacement vertical de la tête porte-outil 21 le long du tronc 23.  According to an exemplary embodiment, the lifting device comprises an actuator, such as a hydraulic cylinder 31 actuable by a lever 32. The lifting device may also comprise two guide rails 33, arranged vertically in the trunk 23 of the mobile base 22, on both sides of the tool head 21, for guiding the vertical movement of the tool head 21 along the trunk 23.
Le dispositif élévateur permet ainsi de lever et descendre des charges importantes telles que les éléments d'outils rotatifs 10 et 11 pour suspendre la tête porte-outil 21 sur la tourelle 16 du groupe de transformation 7 mais permet aussi de rendre la manutention du chariot de transport 20 en usine plus sûre en abaissant le centre de gravité de la charge. En effet, l'abaissement des charges lors du convoyage des outils rotatifs 10 et 11 dans l'usine permet d'éviter que le chariot de transport 20 ne soit déséquilibré par les outils rotatifs 10 et 11 en porte-à-faux. Pour suspendre la tête porte-outil 21 sur la tourelle 16 du groupe de transformation 7, l'interface frontale de maintien comporte par exemple au moins un premier organe d'accroché destiné à coopérer avec au moins un premier organe d'accroché complémentaire de la tourelle 16. The lifting device thus makes it possible to raise and lower important loads such as the rotary tool elements 10 and 11 for suspending the tool-holding head 21 on the turret 16 of the transformation unit 7, but also makes it possible to make the handling of the carriage of transport at the factory safer by lowering the center of gravity of the load. Indeed, the lowering of the loads during the conveying of the rotary tools 10 and 11 in the factory makes it possible to prevent the transport trolley 20 from being unbalanced by the rotary tools 10 and 11 cantilevered. To suspend the tool head 21 on the turret 16 of the transformation unit 7, the front holding interface comprises for example at least one first hook member intended to cooperate with at least one first hook member complementary to the turret 16.
Plus précisément, les premiers organes d'accroché comportent par exemple au moins un premier crochet 34 apte à coopérer avec un premier galet 35 monté libre en rotation de la tourelle 16. Les galets 35 permettent de faciliter le montage et le démontage de la tête porte-outil 21 sur la tourelle 16, en limitant les risques de coincements.  More specifically, the first hook members comprise for example at least one first hook 34 adapted to cooperate with a first roller 35 mounted free to rotate the turret 16. The rollers 35 facilitate the assembly and disassembly of the head gate tool 21 on the turret 16, limiting the risk of jamming.
Les premiers crochets 34 sont portés par la tête porte-outil 21 et les galets 35 par la tourelle 16, ou inversement. Comme mieux visible sur les Figs. 6 et 7, la tête porte- outil 21 comporte par exemple quatre premiers crochets 34. Les premiers crochets 34 s'inscrivent dans un rectangle formé autour des ports supérieur et inférieur 29 et 30 de la tête porte-outil 21 . Les galets 35 font saillie longitudinalement.  The first hooks 34 are carried by the tool head 21 and the rollers 35 by the turret 16, or vice versa. As best seen in Figs. 6 and 7, the tool head 21 comprises for example four first hooks 34. The first hooks 34 fit into a rectangle formed around the upper and lower ports 29 and 30 of the tool head 21. The rollers 35 protrude longitudinally.
Les premiers organes d'accroché permettent le guidage et la fixation de la tête porte-outil 21 au groupe de transformation 7, notamment en évitant les mouvements de la tête porte-outil 21 dans la direction transversale, dans l'axe de rotation des outils rotatifs 10 et 11 .  The first hooking members allow guiding and fixing of the tool head 21 to the processing unit 7, in particular by avoiding the movements of the tool head 21 in the transverse direction, in the axis of rotation of the tools. rotary 10 and 11.
L'interface frontale de maintien peut également comporter au moins un premier épaulement 36, destinée à coopérer avec une cale de soutien 37 fixée à la tourelle 16 pour porter la tête porte-outil 21 (Figs. 6 et 7).  The frontal holding interface may also include at least one first shoulder 36, intended to cooperate with a support wedge 37 attached to the turret 16 to carry the tool head 21 (Figs 6 and 7).
L'interface frontale de maintien comporte par exemple deux premiers épaulements 36. Le premier épaulement 36 est par exemple formé dans un décrochement. Chaque premier épaulement 36 est par exemple agencé entre deux premiers crochets 34. Chaque premier épaulement 36 et deux premiers crochets 34 des premiers organes d'accroché sont par exemple alignés verticalement et peuvent être réalisés dans la tranche d'une même plaque de la tête porte-outil 21 , par exemple par découpe.  The front end interface comprises for example two first shoulders 36. The first shoulder 36 is for example formed in a recess. Each first shoulder 36 is for example arranged between two first hooks 34. Each first shoulder 36 and two first hooks 34 of the first hook members are for example aligned vertically and can be made in the edge of a same plate of the head gate tool 21, for example by cutting.
Lorsque la tête porte-outil 21 est portée par les cales de soutien 37 de la tourelle 16, les premiers crochets 34 sont sensiblement disposés au-dessus des premiers galets 35. Cela permet que la tête porte-outil 21 ne repose pas sur les premiers galets 35 mais que l'essentiel du poids des outils rotatifs 10 et 11 soit repris par les cales de soutien 37 de la tourelle 16. Les cales de soutien 37 permettent ainsi de soulager les premiers galets 35 du poids des outils rotatifs 10 et 11 sensiblement plus fragiles. Les cales de soutien 37, fixées à la tourelle 16, forment la référence verticale. En outre, l'interface frontale de maintien peut comporter au moins une lumière de guidage 38 destinée à coopérer avec un pion de guidage 39 complémentaire porté par la tourelle 16. Deux lumières de guidage 38 peuvent être par exemple prévues, alignés verticalement avec les premiers organes d'accroché, entre ces derniers, et de part et d'autre des ports supérieur et inférieur 29 et 30. When the tool head 21 is carried by the support blocks 37 of the turret 16, the first hooks 34 are substantially disposed above the first rollers 35. This allows the tool head 21 does not rest on the first rollers 35 but that most of the weight of the rotary tools 10 and 11 is taken up by the support wedges 37 of the turret 16. The support wedges 37 thus make it possible to relieve the first rollers 35 of the weight of the rotary tools 10 and 11 substantially more fragile. The support wedges 37 attached to the turret 16 form the vertical reference. In addition, the front holding interface may comprise at least one guide slot 38 intended to cooperate with a complementary guiding pin 39 carried by the turret 16. Two guide slots 38 may for example be provided, aligned vertically with the first ones. hanging members, between the latter, and on both sides of the upper and lower ports 29 and 30.
La lumière de guidage 38 présente une forme en L d'épaisseur plus fine que les ouvertures des premiers crochets 34 des premiers organes de guidage et que les décrochements des premiers épaulements 36, de manière à guider l'accostage de la tête porte-outil 21 sur la tourelle 16. Le pion de guidage 39 plus robuste que les galets 35 permet ainsi le guidage de la tête porte-outil 21 dans la direction dans l'axe de rotation des outils rotatifs 10 et 11 puis, verticalement, en suivant la trajectoire en forme de L des lumières de guidage 38, en évitant d'éventuelles collisions entre les crochets de la tête porte-outil et les galets 35 de la tourelle 16.  The guiding light 38 has an L shape with a thickness thinner than the openings of the first hooks 34 of the first guide members and that the recesses of the first shoulders 36, so as to guide the docking of the tool head 21 on the turret 16. The guiding pin 39 more robust than the rollers 35 thus allows the guide of the tool head 21 to be guided in the direction in the axis of rotation of the rotary tools 10 and 11 and then, vertically, along the path L-shaped guide lights 38, avoiding possible collisions between the hooks of the tool head and the rollers 35 of the turret 16.
La lumière de guidage 38 est par exemple agencée entre le premier épaulement 36 et un premier crochet 34 des premiers organes d'accroché. La lumière de guidage 38, le premier épaulement 36 et les premiers crochets 34 sont par exemple alignés verticalement et réalisés dans la tranche d'une même plaque de la tête porte-outil 21 .  The guide light 38 is for example arranged between the first shoulder 36 and a first hook 34 of the first hook members. The guide light 38, the first shoulder 36 and the first hooks 34 are for example vertically aligned and made in the edge of the same plate of the tool head 21.
La tête porte-outil 21 peut comporter en outre un dispositif de verrouillage configuré pour prendre une position déverrouillée (Fig. 9) ou une position de verrouillage (Fig. 8) dans laquelle le dispositif de verrouillage verrouille le maintien des extrémités avant des mandrins 12 ou des outils 10 et 11 dans les ports supérieur et inférieur 29 et 30.  The tool head 21 may further comprise a locking device configured to assume an unlocked position (Fig. 9) or a locking position (Fig. 8) in which the locking device locks the holding of the front ends of the mandrels 12 or tools 10 and 11 in the upper and lower ports 29 and 30.
Par exemple, le dispositif de verrouillage comporte un système articulé 40, deux pions de verrouillage 41 et un levier d'actionnement 42. Le levier d'actionnement 42 est raccordé aux pions de verrouillage 41 supérieur et inférieur, par le système articulé 40 de sorte que l'actionnement du levier 42 positionne les pions de verrouillage 41 en position déverrouillée dans laquelle les pions de verrouillage 41 sont escamotés dans les ports supérieur et inférieur 29 et 30, à l'écart des outils rotatifs 10 et 11 (Fig. 9) ou en position de verrouillage dans laquelle les pions de verrouillage 41 traversent les ports supérieur et inférieur 29 et 30 et s'insèrent dans des cavités correspondantes 43 ménagées dans les extrémités avant des outils rotatifs 10 et 11 (Fig. 10).  For example, the locking device comprises an articulated system 40, two locking pins 41 and an actuating lever 42. The actuating lever 42 is connected to the upper and lower locking pins 41, by the articulated system 40 so that that the actuation of the lever 42 positions the locking pins 41 in the unlocked position in which the locking pins 41 are retracted into the upper and lower ports 29 and 30, away from the rotary tools 10 and 11 (FIG 9) or in the locking position in which the locking pins 41 pass through the upper and lower ports 29 and 30 and fit into corresponding cavities 43 formed in the forward ends of the rotary tools 10 and 11 (Fig. 10).
Plus précisément, le système articulé 40 comporte par exemple deux bras articulés à l'extrémité du levier d'actionnement 42, opposée à une extrémité raccordée à un actionneur 44, tel qu'un vérin pneumatique du dispositif de verrouillage (Fig. 11 ). Chaque bras est articulé de sorte que par exemple, lorsque le levier 42 est en position basse (Fig. 8), les pions de verrouillage 41 sont insérés dans les cavités 43 des outils rotatifs 10 et 11 . Le pivotement du levier d'actionnement 42 vers le haut (Flèche F1 ), décale le bras supérieur vers le haut (Flèche F2), retirant le pion de verrouillage 41 de la cavité 43 de l'outil rotatif supérieur 10 et décale le bras inférieur vers le bas (Flèche F3), retirant le pion de verrouillage 41 de la cavité 43 de l'outil rotatif inférieur 11 . More specifically, the articulated system 40 comprises for example two articulated arms at the end of the actuating lever 42, opposite to an end connected to an actuator 44, such as a pneumatic jack of the locking device (FIG 11). Each arm is articulated so that, for example, when the lever 42 is in the lower position (FIG 8), the locking pins 41 are inserted into the cavities 43 of the tools rotary 10 and 11. Pivoting the operating lever 42 upward (Arrow F1), shifts the upper arm upward (Arrow F2), removing the locking pin 41 from the cavity 43 of the upper rotary tool 10 and shifts the lower arm downward (arrow F3), removing the locking pin 41 from the cavity 43 of the lower rotary tool 11.
Le dispositif de verrouillage peut également comporter des capteurs de fin de course permettant d'automatiser le verrouillage et déverrouillage du maintien de l'extrémité du mandrin 12 ou de l'outil 10 et 11 , et ainsi de mieux synchroniser la succession des opérations, réduisant les risques de collision.  The locking device may also include end-of-stroke sensors for automating the locking and unlocking of the holding of the end of the mandrel 12 or of the tool 10 and 11, and thus to better synchronize the succession of operations, reducing the risks of collision.
Les ports supérieur et inférieur 29 et 30 peuvent être prévus avec un dispositif élastique, tel qu'un ressort de poussée 45, respectif, destiné à venir en appui contre l'extrémité du mandrin 12 ou de l'outil, par exemple via une rondelle 46 en butée en fond d'alésage des ports 29 et 30. Le dispositif élastique est agencé de manière à pouvoir être repoussé par le mandrin 12 ou de l'outil dans le fond du logement du port supérieur ou inférieur 29 et 30 (Fig. 10). Les collisions du mandrin 12 ou de l'outil 10 et 11 sont ainsi évitées avec la tête porte-outil 21 en position déverrouillée par manipulation du mandrin 12 ou de l'outil 10 et 11 à l'extrémité arrière par la pince des moyens d'entraînement motorisés, côté opposé conducteur.  The upper and lower ports 29 and 30 may be provided with an elastic device, such as a respective thrust spring 45, intended to bear against the end of the mandrel 12 or of the tool, for example via a washer 46 in abutment bottom ports 29 and 30. The elastic device is arranged to be pushed by the mandrel 12 or the tool in the bottom of the housing of the upper or lower port 29 and 30 (Fig. 10). The collisions of the mandrel 12 or the tool 10 and 11 are thus avoided with the tool head 21 in the unlocked position by manipulation of the mandrel 12 or the tool 10 and 11 at the rear end by means of the clamping means. motorized drive, opposite driver side.
La tête porte-outil 21 peut être prévue amovible, c'est-à-dire détachable de la base mobile 22 du chariot de transport 20. Ainsi, la base mobile 22 peut être commune pour différentes têtes, telles que des têtes porte-manchons et/ou des têtes porte-outil de différents diamètres.  The tool head 21 may be provided removable, that is to say, detachable from the mobile base 22 of the transport carriage 20. Thus, the movable base 22 may be common for different heads, such as sleeve heads and / or tool heads of different diameters.
Pour suspendre la tête porte-outil 21 sur la base mobile 22 du chariot de transport 20, la tête porte-outil comporte par exemple une interface arrière de maintien destinée à coopérer avec la base mobile 22 et comprenant au moins un second organe d'accroché destiné à coopérer avec au moins un second organe d'accroché complémentaire de la base mobile 22.  To suspend the tool head 21 on the mobile base 22 of the transport carriage 20, the tool head comprises for example a rear holding interface intended to cooperate with the mobile base 22 and comprising at least one second hook member. intended to cooperate with at least one second hook member complementary to the mobile base 22.
Plus précisément, les seconds organes d'accroché comportent au moins un second crochet 47 apte à coopérer avec un second galet 48 monté libre en rotation de la base mobile 22. Les galets 48 permettent de faciliter le montage et le démontage de la tête porte-outil 21 sur la base mobile 22, en limitant les risques de coincements.  More specifically, the second hooking members comprise at least one second hook 47 adapted to cooperate with a second roller 48 mounted to rotate freely of the movable base 22. The rollers 48 facilitate assembly and disassembly of the carrier head. tool 21 on the mobile base 22, limiting the risk of jamming.
Les seconds crochets 47 sont portés par la tête porte-outil 21 et les galets 48 par la base mobile 22, ou inversement. Comme mieux visible sur les Figs. 4 et 6, la tête porte-outil 21 comporte par exemple quatre seconds crochets 47. Les quatre seconds crochets 47 s'inscrivent dans un rectangle formé autour des ports supérieur et inférieur 29 et 30 de la tête porte-outil 21 , par exemple à l'arrière des quatre premiers crochets 34 des premiers organes d'accroché. Les seconds galets 48 font saillie longitudinalement. Les seconds organes d'accroché permettent le guidage et la fixation de la tête porte-outil 21 à la base mobile 22. The second hooks 47 are carried by the tool head 21 and the rollers 48 by the mobile base 22, or vice versa. As best seen in Figs. 4 and 6, the tool head 21 comprises, for example, four second hooks 47. The four second hooks 47 fit into a rectangle formed around the upper and lower ports 29 and 30 of the tool head 21, for example to the back of the first four hooks 34 of the first hooked organs. The second rollers 48 protrude longitudinally. The second hooking members allow guiding and fixing of the tool head 21 to the mobile base 22.
L'interface arrière de maintien peut également comporter au moins un second épaulement 49, destinée à coopérer avec une cale de soutien 50 fixée à la base mobile 22 pour porter la tête porte-outil 21 (Figs. 4 et 6).  The rear holding interface may also include at least one second shoulder 49, intended to cooperate with a support wedge 50 fixed to the mobile base 22 to carry the tool head 21 (Figs 4 and 6).
L'interface arrière de maintien comporte par exemple deux seconds épaulements 49. Le second épaulement 49 est par exemple formé dans un décrochement. Chaque second épaulement 49 est par exemple agencé entre deux seconds crochets 47. Chaque second épaulement 49 et deux seconds crochets 47 des seconds organes d'accroché sont par exemple alignés verticalement et peuvent être réalisés dans la tranche d'une même plaque de la tête porte-outil 21 , par exemple par découpe.  The rear holding interface comprises for example two second shoulders 49. The second shoulder 49 is for example formed in a recess. Each second shoulder 49 is for example arranged between two second hooks 47. Each second shoulder 49 and two second hooks 47 of the second hook members are for example aligned vertically and can be made in the edge of a same plate of the head gate tool 21, for example by cutting.
Lorsque la tête porte-outil 21 est portée par les cales de soutien 50 de la base mobile 22, les seconds crochets 47 sont sensiblement disposés au-dessus des seconds galets 48. Cela permet que la tête porte-outil 21 ne repose pas sur les seconds galets 48 mais que l'essentiel du poids des outils rotatifs 10 et 11 soit repris par les cales de soutien 50 de la base mobile 22. Les cales de soutien 50 permettent ainsi de soulager les seconds galets 48 du poids des outils rotatifs 10 et 11 sensiblement plus fragiles.  When the tool head 21 is carried by the support blocks 50 of the mobile base 22, the second hooks 47 are substantially disposed above the second rollers 48. This allows the tool head 21 does not rest on the second rollers 48 but that most of the weight of the rotary tools 10 and 11 is taken up by the support wedges 50 of the mobile base 22. The support blocks 50 thus relieve the second rollers 48 of the weight of the rotary tools 10 and 11 significantly more fragile.
L'opérateur souhaite monter les outils rotatifs dans un groupe de transformation The operator wants to mount the rotary tools in a transformation group
7. Pour cela, l'opérateur muni une tête porte-outil 21 de mandrins 12 ou d'outils rotatifs 10 et 11 , en insérant leurs extrémités avant dans les logements des ports supérieur et inférieur 29 et 30. Puis, le maintien des extrémités avant des mandrins 12 ou des outils est verrouillé dans les ports supérieur et inférieur 29 et 30 (Fig. 8) et la tête porte-outil 21 munis de mandrins 12 ou d'outils rotatifs 10 et 11 est suspendue sur la base mobile 22 du chariot de transport 20. 7. For this, the operator has a tool head 21 of mandrels 12 or rotary tools 10 and 11, inserting their front ends in the housing of the upper and lower ports 29 and 30. Then, the maintenance of the ends Before mandrels 12 or tools are locked in the upper and lower ports 29 and 30 (Fig. 8) and the tool head 21 provided with mandrels 12 or rotary tools 10 and 11 is suspended on the movable base 22 of the machine. transport trolley 20.
Le chariot de transport 20 transporte les outils rotatifs 10 et 11 en position basse vers le groupe de transformation 7 (Fig. 5) où il lève la tête porte-outil 21 et les outils rotatifs 10 et 11 en position haute par le dispositif élévateur (Figs. 3 et 4).  The transport carriage 20 transports the rotary tools 10 and 11 in the down position to the processing unit 7 (Fig. 5) where it raises the tool head 21 and the rotary tools 10 and 11 in the up position by the lifting device ( Figs 3 and 4).
La tête porte-outil 21 est alors surélevée de sorte que le pion de guidage 39 s'insère dans la lumière de guidage 38, les cales de soutien 37 s'insèrent sous les premiers épaulements 36 et les premiers galets 35 s'insèrent dans les ouvertures des premiers crochets 34. Puis, l'opérateur avance sensiblement le chariot de transport 20 jusqu'à ce que le pion de guidage 39 soit au fond de la partie horizontale de la lumière de guidage 38. Le chariot de transport 20 abaisse alors sensiblement la tête porte-outil 21 , de sorte que la tête porte-outil 21 soit suspendue sur les cales de maintien 50 de la tourelle 16, que le pion de guidage 39 soit reçu au fond de la partie haute de la lumière de guidage 38 et que les premiers crochets 34 soient agencés sensiblement au-dessus des premiers galets 35. La tête porte-outil 21 du chariot de transport 20, munie de mandrins 12 ou d'outils 10 et 11 est alors fixée à la tourelle 16 (Figs. 6 et 7). The tool head 21 is then raised so that the guiding pin 39 fits into the guide lumen 38, the support wedges 37 fit under the first shoulders 36 and the first rollers 35 fit into the opening of the first hooks 34. Then, the operator substantially advances the transport carriage 20 until the guide pin 39 is at the bottom of the horizontal portion of the guide slot 38. The transport carriage 20 then lowers substantially the tool head 21, so that the tool head 21 is suspended on the holding wedges 50 of the turret 16, the guide pin 39 is received at the bottom of the upper portion of the guide slot 38 and that the first hooks 34 are arranged substantially above the first rollers 35. The tool head 21 of the transport carriage 20, provided with mandrels 12 or tools 10 and 11 is then attached to the turret 16 (Figs 6 and 7).
Les pinces des moyens d'entraînement motorisés côté opposé conducteur, coopèrent alors avec les extrémités arrière des mandrins 12 ou des outils 10 et 11 , verrouillant le maintien des extrémités arrière des mandrins ou des outils par le groupe de transformation 7.  The grippers of the motorized drive means on the opposite conductor side, then cooperate with the rear ends of the mandrels 12 or tools 10 and 11, locking the maintenance of the rear ends of the mandrels or tools by the transformation unit 7.
Le maintien des extrémités avant des outils est alors déverrouillé par le chariot de transport 20. Le dispositif élastique autorise alors le déplacement sensible du mandrin 12 ou de l'outil par la pince dans les ports supérieur ou inférieur 29 et 30 en évitant les collisions (Fig. 9). Le dispositif élastique garanti le contact au fond de la pince.  The maintenance of the front ends of the tools is then unlocked by the transport carriage 20. The elastic device then allows the sensitive movement of the mandrel 12 or tool by the clamp in the upper or lower ports 29 and 30 avoiding collisions ( Fig. 9). The elastic device guarantees the contact at the bottom of the clamp.
Pour démonter les outils du groupe de transformation 7, l'opérateur commence par fixer la tête porte-outil 21 du chariot de transport 20 démunie d'outil à la tourelle 16. Puis l'opérateur déverrouille.  To disassemble the tools of the transformation group 7, the operator begins by fixing the tool head 21 of the transport trolley 20 without tool to the turret 16. Then the operator unlocks.
Puis, les extrémités avant des mandrins 12 ou des outils 10 et 11 sont engagées dans les ports supérieur et inférieur 29 et 30 de la tête porte-outil 21 fixée à la tourelle 16. Puis, l'opérateur verrouille le maintien des extrémités avant des mandrins 12 ou de outils 10 et 11 par le chariot de transport 20 et l'opérateur déverrouille le maintien des extrémités arrière des mandrins 12 ou des outils 10 et 11 par le groupe de transformation 7 (Fig. 8).  Then, the front ends of the mandrels 12 or tools 10 and 11 are engaged in the upper and lower ports 29 and 30 of the tool head 21 fixed to the turret 16. Then, the operator locks the maintenance of the front ends of the chucks 12 or tools 10 and 11 by the transport trolley 20 and the operator unlocks the holding of the rear ends of the chucks 12 or tools 10 and 11 by the transformation unit 7 (Fig. 8).
La manipulation des outils rotatifs 10 et 11 vers ou à l'écart des groupes de transformation 7 est facilitée, ceux-ci pouvant être changés rapidement, de façon reproductible et de manière simple.  Manipulation of rotating tools 10 and 11 to or away from processing groups 7 is facilitated, which can be changed quickly, reproducibly and in a simple manner.
