- the output shaft 301 of the gearmotor 30 is integral in rotation with the launch arm 1.
- the output shaft 301 of the gearmotor 30 and the launch arm 1 are coupled, preferably directly coupled.
- the arm 1 comprises a device 10 for fixing the end of the output shaft 301. This makes it possible to make possible the rotation of the launching arm 1 around the axis A1.

- the control unit also advantageously comprises processing means, such as a microprocessor and a non-volatile memory. It is for example possible to store programs for varying the throws and / or the operating conditions.
- the electronic card can be integrated into a box and connected to a drive. The latter controls the speed of the geared motor and controls its position by means of a resolver.
- the launch cycle advantageously comprises a first angular displacement Da1, called positioning displacement Da1 of target 2, at a first speed of rotation w1, from the launch arm 1 to a starting position Pd of target 2.
- the first angular displacement Da1 is variable so as to vary the starting position of the target. It can for example cover an angular sector between 30 and 120 °.
- the first speed of rotation is low so as to minimize the centrifugal force applied to the target during this phase. If this force is small enough, it can be neglected.
- it can be fully compensated by forces acting in reaction, in particular frictional forces on the launching plate or a force applied by a contact element with the target during this phase.
- the first speed of rotation is less than 20 rpm.
- the movement of the arm includes an acceleration phase, a stabilized speed phase and a deceleration phase to the position to be reached.
- the acceleration and deceleration phases can be brief.
- the rotational speeds considered in the present description are understood to mean the maximum speed obtained during a movement of the arm, typically the stabilized speed.
- the member for controlling the rotation of the geared motor 30 is configured to control the launch arm 1 from a position called the original position Po.
- This original position Po corresponds to a position in which the arm 1 is located when the launch device 100 is at rest, that is to say when no launch cycle is in progress.
- the original position Po can be variable.
- the positioning displacement Da1 of targets 2 is followed by a second angular displacement Da2, controlled by the piloting member.
- This second angular displacement Da2 is called displacement of projection Da2 of targets 2.
- This displacement of projection Da2 is carried out at a second speed of rotation w2, of the launch arm 1 from the starting position Pd of target 2.
- the second rotational speed w2 is greater than the first rotational speed w1. This then makes it possible to accelerate the rotational movement of the launching arm 1 and consequently to give speed to the target 2 intended to be launched and ejected from the device 100.
- the second angular displacement Da2 is substantially equal to 130 °.
- the second speed of rotation can reach 450 rpm.
- This third angular displacement Da3 is called a return displacement Da3.
- This third displacement Da3 has a third speed of rotation w3, from the launch arm 1 to the original position Po.
- This third displacement Da3 corresponds to a deceleration phase of the launch arm 1. Indeed, the third speed of rotation w3 is lower than the second speed of rotation w2.
- the third angular displacement Da3 is substantially equal to 140 °.
- the pilot is configured so that the positioning movement Da1 causes a target 2 to pass from an original position Po to the starting position Pd which is desired for target 2.
- the pilot unit is configured so as to vary the starting position Pd.
- the user can configure before the start of the launch cycle, the starting position Pd according to the direction in which he wants the target 2 to be launched.
- the direction of exit of targets from the device which is along an axis A2 depends on the starting position Pd, corresponding to the position in which the projection displacement Da2 is initiated.
- the output axis A2 of the target is different depending on the position of the starting position Pd.
- the target exit axis A2 is preferably parallel to the launch arm 1 when the arm 1 is positioned in the starting position Pd.
- the target 2 is advantageously positioned halfway along the launch arm 1 against the launch arm 1 and on a launch plate 11.
- a guide rail disposed on the launch plate to serve as a guide.
- a guide rail 12 concentric with the axis A1 is located on the internal edge of the launching plate 11.
- a finger 13 movable in rotation around an axis A3 parallel to A1 is equipped.
- a return spring 14 (or any other return means).
- a strip 16 covered or made of an elastomer (or having at least an improved adhesion relatively to a direct contact of a target with the launching arm) is fixed along the arm 1.
- a retaining member is also present, for example in the form of a leaf spring 15.
- the leaf spring 15 is fixed to the upper part of the launching arm 1, preferably between the guide rail 12 and the finger 13.
- the blade 15 may be in the form of a portion of sheet metal, a lower face of which is configured to be applied on an upper face of the target. We can play on the elastic deformation capacity of the blade 15 to operate the reversible support on the target.
- other elastic return solutions are possible, in particular with a flexible connection of the holding member relative to the launch arm, or any other spring means.
- the holding member prefferably has a bearing surface on the target which is located at rest at a height level lower than that of the top of the target and which moves in a reversible manner, to a position more in height so as to rest on the top of the target while exerting its support.
- the lower face has a convex profile so that the docking of this blade 15 on the target takes place gradually and elastically raises the blade.
- the latter is preferably positioned on the arm so that the pressure on the target takes place at the level of the axis of symmetry of the latter.
- This member is configured to laterally maintain the target without preventing its movement induced by the launching arm on the plate.
- targets are used having an upper face with a planar apex and the member, such as blade 15, is configured to apply there.
- This flat part may be surrounded by a rim which can optionally serve as a wedge for the edge of the blade, which is then dimensioned so that its width corresponds at most to the width of the upper face of the target surrounded by the rim.
- the finger 13 forces the target 2 to come into contact with the rail 12, the pressure exerted by the return spring 14 being greater. to that coming from the leaf spring 15, the target 2 is positioned against the slide 16.
- the movement to Pd taking place at a first speed of rotation w1 being advantageously a slow speed, when the target 2 is no longer in contact with the finger 13, it is the pressure exerted by the leaf spring 15 which retains its relative position with respect to the guide rail 12. It is the acceleration phase during the angular displacement Da3 which will cause the movement of the target on the slide 16 until it is ejected.
- the control member adjusts the original position Po and the starting position Pd of the drive system 3, the rotation of the launching arm 1 along the axis A1 is produced by the electric geared motor 30 including the launching arm 1 is integral in rotation.
- the launching arm 1 follows the following path: it moves according to a first angular displacement Da1, called positioning displacement Da1 of target 2, at a speed of rotation w1.
- the arm 1 moves to the starting position Pd of target 2.
- the starting position Pd of target 2 is commanded by the piloting unit, it can then vary from one launch cycle to another launch cycle.
- the arm 1 is then in contact with the target 2 at the starting position Pd.
- the arm 1 then begins a so-called projection phase Da2 of target 2 by exerting a thrust on the target 2.
- This projection phase Da2 in other words displacement of projection Da2 corresponds to a second angular displacement Da2, at a second speed of rotation w2 , of the launch arm 1.
- the second speed of rotation w2 being greater than the first speed of rotation w1 makes it possible to accelerate the movement of the arm 1 and to move the target 2 with a sufficiently high speed to allow the projection of the target 2 along an axis A2 outside of the launching plate 11.
- the arm 1 initiates a third angular displacement Da3, called return displacement, at a third speed of rotation w3.
- the return movement stops when the launching arm 1 is at the original position Po, which is the same position that the arm 1 was in when initiating the first angular movement Da1.
- the piloting member is capable of moving the launching arm 1 according to a launching cycle comprising three different phases at three different speeds, each phase possibly having a different angular amplitude. This eliminates the need for the use of complex mechanism systems such as a spring, a connecting rod, a stop surface, etc.
- the device 100 is then easier to use. In addition, this makes it possible to have a less bulky device 100.
