Pour atteindre ce but elle propose un système de commande qui est caractérisé en ce qu'il comprend un poste central de commande destiné à piloter les dispositifs porte-pièce à l'aide d'un dispositif de liaison par rayons infrarouges. To achieve this goal, it offers a control system which is characterized in that it comprises a central control station intended to control the workpiece support devices using a connection device by infrared rays.
Selon une caractéristique avantageuse de l'addition , au poste central et à chaque dispositif porte-pièce est associé un ensemble émetteur-récepteur de rayons infrarouges pour pouvoir établir des liaisons bidirectionnelles entre le poste central et chaque dispositif. According to an advantageous characteristic of the addition, the central station and each workpiece device is associated with a transmitter-receiver set of infrared rays so as to be able to establish bidirectional links between the central station and each device.
Selon encore une autre caractéristique avantageuse de l' addition, le poste central est adapté pour être relié à un dispositif de commande manuel et/ou à un centre de commande numérique tel qu'un automate program-: mable ou une machine à commande numérique. According to yet another advantageous feature of the addition, the central station is adapted to be connected to a manual control device and / or to a digital control center such as a programmable automaton or a numerically controlled machine.
D'autres buts, caractéristiques et avantages de l'addition apparaîtront clairement a la lumière de la description explicative qui va suivre faite en référence à la figure unique annexe représentant sous forme d'un schéma-bloc un mode de réalisation de l'addition, donné simplement à titre d'exemple. Other objects, characteristics and advantages of the addition will appear clearly in the light of the explanatory description which will follow made with reference to the single annex figure representing in the form of a block diagram an embodiment of the addition, given simply as an example.
La figure montre un système de commande selon la présente addition, qui comprend un poste central 1 formant un poste fixe et un certain nombre de poste mobile dont seulement deux postes 2 et 3 sont représentés. The figure shows a control system according to the present addition, which comprises a central station 1 forming a fixed station and a number of mobile stations of which only two stations 2 and 3 are shown.
Chaque poste comporte l'agencement électronique de commande des vérins à fluide comprimé pour l'actionnement des moyens de fixation par serrage, bridage ou analogue des pièces à usiner, qui sont prévues dans un dispositif porte-pièces faisant objet de la demande de brevet principal NO 83 18 965.Each station includes the electronic control arrangement of the compressed fluid cylinders for actuating the means of fixing by clamping, clamping or the like of the workpieces, which are provided in a workpiece carrier device which is the subject of the main patent application. NO 83 18 965.
Le poste central 1 est adapté pour piloter les postes mobiles 2, 3. A cette fin le poste central comprend une unité centrale de traitement d'informations, avantageusement à microprocesseur ,et un dispositif de commande manuelle extérieure 4 permettant de définir le poste mobile auquel des ordres doivent être transmis et les opérations de travail à accomplir dans le dispositif porte-pièce correspondant, tel que par exemple l'effort de serrage ou de desserrage que doivent produire les vérins du dispositif. Le dispositif de commande 4 peut être réalisé de toute manière appropriée. The central station 1 is adapted to control the mobile stations 2, 3. To this end the central station comprises a central information processing unit, advantageously with a microprocessor, and an external manual control device 4 making it possible to define the mobile station to which orders must be transmitted and the work operations to be carried out in the corresponding workpiece-holding device, such as for example the tightening or loosening force which the jacks of the device must produce. The control device 4 can be made in any suitable way.
Il peut comprendre avantageusement des roues codeuses et une touche de validation de lecture de ces roues. On pourrait également prévoir une interface B C D (décimal codé binaire). Ces mesures permettent l'entrée du numéro du poste mobile à piloter et l'entrée des pressions de serrage ou de desserrage.It can advantageously include coding wheels and a button for validating the reading of these wheels. One could also provide an interface B C D (binary coded decimal). These measurements allow the entry of the number of the mobile unit to be controlled and the entry of tightening or loosening pressures.
Selon la présente addition il est avantageux d'adapter le poste central 1 pour qu'il puisse être relié à un centre de commande numérique externe 5, tel qu'un automate programmable ou une machine à commande numérique. According to the present addition, it is advantageous to adapt the central station 1 so that it can be connected to an external digital control center 5, such as a programmable controller or a machine with digital control.
Le poste central comporte en outre des moyens d'alarme formés par exemple par des diodes électroluminescentes (non représentées), qui sont agencées pour afficher toute anormalité dans le fonctionnement des dispositifs porte-pièce à usiner, pilotés par le poste central. Bien entendu ce dernier peut être équipé d'autrz moyens appropriés pour assurer le fonctionnement parfait et la sécurité du système de commande et des dispositifs porte-pièces. The central station further comprises alarm means formed for example by light-emitting diodes (not shown), which are arranged to display any abnormality in the operation of the workpiece carrier devices, controlled by the central station. Of course the latter can be equipped with other means suitable for ensuring the perfect functioning and safety of the control system and of the workpiece carrier devices.
Concernant les postes mobiles 2, 3,il est à noter qu'un tel poste comporte également avantageusement une unité centrale de traitement telle qu'un microprocesseur (non représenté)#destiné à dialoguer avec le poste central pour assurer le pilotage correcte des vérins du dispositif porte-pièce et pour signaler au poste central toute anormalité dans le fonctionnement de ce dispositif. Bien entendu on pourrait prévoir dans les postes mobiles tout moyen approprié destiné à garantir le fonctionnement correct et sûr du dispositif porte-pièce correspondant. Regarding the mobile stations 2, 3, it should be noted that such a station also advantageously includes a central processing unit such as a microprocessor (not shown) # intended to interact with the central station to ensure the correct control of the jacks of the workpiece support device and to report any abnormality in the operation of this device to the central station. Of course one could provide in mobile stations any suitable means intended to guarantee the correct and safe operation of the corresponding workpiece holding device.
Selon la présente addition les dialogues entre le poste central fixe 1 et chaque poste mobile 2, 3 se font à l'aide d'un dispositif de liaison bidirectionnelle par rayo#infrarouges6. A cette fin le poste central et les postes mobiles comportent chacun un ensemble émetteur-récepteur de rayonsinfrarouges7. Les postes peuvent donc dialoguer sans qu'il existe un lien physique entre-eux. Dans ce même but, c'est-à-dire pour éviter des liaisons physiques permanentes, le poste mobile 3 est par exemple connectable au poste central 1, plus précisément à une borne de rechargement 8, des batteries d'accumulateur électriquesprévues dans le dispositif porte-pièce , décrites dans la demande de brevet principal. According to the present addition, the dialogs between the fixed central station 1 and each mobile station 2, 3 are made using a bidirectional link device by infrared rayo # 6. To this end, the central station and the mobile stations each include an infrared ray transmitter-receiver unit7. The stations can therefore communicate without there being a physical link between them. For the same purpose, that is to say to avoid permanent physical connections, the mobile station 3 is for example connectable to the central station 1, more precisely to a recharging terminal 8, of electric accumulator batteries provided in the device workpiece holders, described in the main patent application.
