Spring Launcher - fischertechnik PROFI Dynamic XL Begleitheft

The support surfaces for the balls tilt alternately from side to side. This
makes the balls roll from right to left - and vice versa - moving them up
step for step. This procedure is repeated until the balls have reached
the top step. From here the then shoot back down over the flex-rails.
The stopping point is an interesting obstacle in this model. Place
a ball at the stopping point. When a second ball rolls into the
stopping point, it knocks the present ball out. This means the
second ball rolling down remains at the stopping point and the
previous ball travels on to the next elevator.
Task:
You can see how your ball rolls over the stopping point when another ball is
not present in the stopping point. Why is it necessary to first place a ball at
the stopping point?
If a ball is not present at the stopping point, the incoming ball has so much force, that it cannot be stopped
by the stopping point. When a ball is in position at the stopping point, it is knocked out of the stopping
point by the rolling ball as described.
■ A pinball machine contains a spring launcher which
is almost identical to yours. In a pinball machine the
ball is brought into play by a spring launcher. The
bolt is pulled back and released, so that it hits the
ball which rolls into the playing field at high speed.

Your stage conveyor has a trap door, which functions in a
manner similar to your chain conveyor model.

Tip:
If the balls do not roll over to the
other side, adjust the drive shafts so
that are offset precisely. When the
left push rod is at the lowest point,
the right push rod should be adjusted
so that it is at the highest point.
Obstacle - trap door
Tip:
See chain conveyor.
Obstacle - stopping point
Tip:
If the balls start collecting at the
stopping point, check whether
the supports and components at
the stopping point are assembled
precisely. Moreover the balls should
not be slowed down above the
stopping point in the obstacle course.
For this reason you should also pay
attention to exact assembly here.

Spring Launcher

Tip:
A maximum of one ball can be
positioned in the spring launcher
model.
