Machine for launching targets with rotating barrel

Abstract

A machine for launching targets, the machine having a chassis on which a barrel is mounted mobile in rotation, a launching arm mounted mobile in rotation according to a cycle and configured to project at least one target, the cycle including a phase of arming by stressing a spring member until an armed angular position of the launching arm, a launching phase wherein a releasing of stress of the spring member is configured to rotate the arm and a phase of returning to an angular position for rearming the launching arm. The axis of rotation of the barrel and the axis of rotation of the arm are combined.

1 . A machine for launching targets comprising:
 a chassis on which a barrel is mounted mobile in rotation along an axis of rotation, said barrel comprising a plurality of columns for storing targets in a stack,   a launching arm mounted mobile in rotation along an axis of rotation according to a cycle and configured to project at least one target extracted from the barrel, the cycle comprising a phase of arming the launching arm by stressing, by a motorisation assembly, of a spring member to an armed angular position of the launching arm, a launching phase wherein a releasing of stress of the spring member from the armed angular position is configured to rotate the arm while the at least one target is born on the launching arm, and a phase of returning to a rearming angular position of the launching arm;   a drive system for rotating the barrel, said system being configured to produce a rotation of the barrel during the arming phase;   and wherein the axis of rotation of the barrel and the axis of rotation of the arm are combined;   and wherein the drive system comprises a first part mounted on the launching arm and a second part integral with the rotation of the barrel, the first part being configured to generate a force for driving the second part during the arming phase.   
     
     
         2 . The machine according to  claim 1 , wherein the drive system comprises a conversion element between the first part and the second part, the conversion element receiving the drive force and rotating the second part. 
     
     
         3 . The machine according to  claim 1 , wherein the first part comprises a thrust member off-centre relative to the axis of rotation. 
     
     
         4 . The machine according to  claim 3 , wherein the thrust member comprises a roller rotatably mounted on the launching arm. 
     
     
         5 . The machine according to  claim 1 , wherein the second part comprises a gearwheel. 
     
     
         6 . The machine according to  claim 5 , wherein the drive system comprises a conversion element between the first part and the second part, the conversion element receiving the drive force and rotating the second part, the first part comprises a thrust member off-centre relative to the axis of rotation, the conversion element comprises a ratchet configured to drive the gearwheel and a drive member on which is mounted the ratchet, the drive member comprising a support surface of the thrust member. 
     
     
         7 . The machine according to  claim 6 , wherein the support surface has a convex curved line profile. 
     
     
         8 . The machine according to  claim 6 , wherein the drive member is rotatably mounted relative to the support. 
     
     
         9 . The machine according to  claim 6 , wherein the ratchet is rotatably mounted on the drive member. 
     
     
         10 . The machine according to  claim 9 , wherein the conversion element comprising a member for returning the ratchet configured to maintain the ratchet born on the gearwheel. 
     
     
         11 . The machine according to  claim 9 , wherein the ratchet is rotatably mounted on the drive member by way of a shaft, said shaft passing through a space configured to guide the shaft and formed in the support. 
     
     
         12 . The machine according to  claim 1 , wherein the axis of rotation of the barrel is perpendicular to a plane comprising the support and is placed in the centre of the barrel.
