Dynamic Simulation drop several parts parts to conveyor question

There is a moving conveyor.

The bunker is moving along with conveyor and drop a part to conveyor belt.

Part is dropped when bunker and conveyor speeds are getting equal.

Than bunker returns back to initial position and repeat the next drop.

 

As for creation the simulation I take the Spatial joint for the Parts.

Part can be tied either to bunker or to the grounded part.

 

In case of buker the special route should be created to prevent the first part “grabbing” back when bunker returns.

In case of tieup to grounded part the special route should be creates for the second part since it travels in bunker’s “zig-zag” direction until it will be dropped.

 

The question is:

Is it possible to make it more simpe as I need to drop more than two parts at simulation?

It would be good if you can post your data set here so we can understand your setting (gravity, joints and load) and better answer your question.

Here is video.

I have quite weird graph for carriage droping lists but should also make the sophisticated graph for each list too.

In this case carriage and all lists are tied to grounded surface in the DS.

If I would tied the list to carriage I would get the same (even worse for creation) graph too for each list.

The only hypothetic solution would be a tear off from joint at some point as it really happened in real life.

If I would shoot a ball from cannon and while it still flying I would turn a gun to some angle, the ball will fly in same direction.

It has nothing to do with cannon anymore...

From the video, I cannot see your joint setting. For your example of Cannon and Ball, if the initial velocity direction of the ball is not defined by the axis of the cannon, the rotation of the Cannon will not affect the trajectory of the ball.

Regarding the cannon - yes it possible but if you had just a one shot.

In my case list before has been droped travels on carriadge and its not alone, I've got twelve.

Carriage makes forth / back move and makes shift regarding the moving base.

Carirage has Slide Joint regarding the grounded surface.

Each list is Spatial Joint regarding the same grounded surface.

List makes left and down move before drop.

Before each list is dropped it has a special graph to follow the carriadge, other word to

"pretend" it is the carriadge.

If I would connect list to carriadge I would be supposed to make a special graph of

the dropped list to make it stand still.
