Description

       

   <EMI ID=1.1> 

  
La présente invention concerne les machines à graver

  
ou à copier pourvues d'un système pantographique mobile dans trois directions. Elle réside dans le fait que le moteur

  
 <EMI ID=2.1> 

  
le support du système pantographique pivotable sur un axe horizontal et participe aux mouvements du support autour de cet' axe. Le dispositif conforme à l'invention présente sur

  
les conceptions de machines de l'espèce connues jusqu'à ce jour l'avantage de permettre l'emploi de courroies en forme de coin pour transmettre la force motrice parce qu'il n'est pas nécessaire de faire sortir les courroies du plan des poulies. Or, l'emploi de courroies en forme de coin présente sur celui des courroies à section plate ou ronde l'avan-

  
 <EMI ID=3.1> 

  
très peu de placée, des énergies de commande beaucoup plus considérables. 

  
Un autre avantage de la nouvelle conception est que les articulations du système pantographique ne doivent pas supporter le poids du moteur. En outre, grâce au déplacement du centre de gravité du moteur dans l'axe de rotation du support

  
du pantographe, on supprime toute influence du poids du moteur sur le support du pantographe; ou bien encore, en disposant le moteur de l'autre côté de l'axe de rotation, on assure aussi un équilibre partiel du poids du pantographe.

  
Le dessin montre sohématiquement un exemple de réalisation de l'invention.

  
La fig. 1 est une vue postérieure en plan et la fig. 2 une vue en plan de dessus de la partie supérieure d'une machine à copier et la fig. 3 montre la commande par courroies

  
à l'état tendu.

  
Sur le support 1 de la machine est logé le support de pantographe 3 sur un axe horizontal 2; ce support porte sur

  
 <EMI ID=4.1> 

  
connue. Un moteur 6 logé latéralement sur le support de pantographe 3 sert à actionner la broche de l'outil 5 reposant sur l'un des bras du système pantographique. Le mouvement est transmis de la poulie à gradins 7 du moteur par une courroie conique 8 à une deuxième poulie à gradins, la poulie 9. Cette poulie est''portée par un bras 10 qui pivote <EMI ID=5.1>  <EMI ID=6.1> 



   <EMI ID = 1.1>

  
The present invention relates to engraving machines

  
or to copy provided with a pantographic system movable in three directions. It lies in the fact that the engine

  
 <EMI ID = 2.1>

  
the support of the pantographic system can be pivoted on a horizontal axis and participates in the movements of the support around this axis. The device according to the invention is present on

  
machine designs of the kind known to date have the advantage of allowing the use of wedge-shaped belts to transmit the motive force because it is not necessary to take the belts out of the plane of the pulleys. However, the use of wedge-shaped belts has the advantage over that of belts with a flat or round section.

  
 <EMI ID = 3.1>

  
very little placed, much more considerable control energies.

  
Another advantage of the new design is that the joints of the pantographic system do not have to support the weight of the engine. In addition, thanks to the displacement of the engine's center of gravity in the axis of rotation of the support

  
pantograph, any influence of the weight of the motor on the pantograph support is eliminated; or else, by placing the motor on the other side of the axis of rotation, a partial balance of the weight of the pantograph is also ensured.

  
The drawing shows schematically an exemplary embodiment of the invention.

  
Fig. 1 is a rear plan view and FIG. 2 a top plan view of the upper part of a copying machine and FIG. 3 shows the belt drive

  
in the tense state.

  
On the support 1 of the machine is housed the pantograph support 3 on a horizontal axis 2; this support relates to

  
 <EMI ID = 4.1>

  
known. A motor 6 housed laterally on the pantograph support 3 serves to actuate the spindle of the tool 5 resting on one of the arms of the pantographic system. The movement is transmitted from the stepped pulley 7 of the engine by a conical belt 8 to a second stepped pulley, the pulley 9. This pulley is '' carried by an arm 10 which pivots <EMI ID = 5.1> <EMI ID = 6.1>
