How can an Over Head Transporter object be simulated in a model?

I want to use an Over Head Transporter like AGV when making a model.
The Over Head Transporter is called as "Kuatran" and
it's movies is .

The target is how many vehicles is the best optimzed?

Which method is the easiest way to make the model?
1) To use conveyor object hanged the ceiling?
2) To use AGV and network? This way is some difficult to display?
3) Another good method?

Where can I find the over head vehicle?

Help me!

Hi,
I would use travelpath with networknodes and TaskExecuters for this model. They are created fast and easy, and their controlling is quite easy too. Thinks like distance between TE´s and so on, can be set in GUI.

What difficultys you think are with display this way?

Greetings

Thanks, Sebastian.

I made a test model for OHT 'Kuatran".
But it need some more features.

1) The rear AGV passes over the front AGV. Yes it does not keep the distance between them. I set the non-passing in the network. But it is not valid.

2) How can the gripper be displayed in the AGV?
The gripper is the device for gripping the item and it downed for doing it and up again for moving through the pass-line.
It can be found in the youtube movie.

Help me some more!

The OHT is stopping at the location for gripping the item and the gripper up/down action need some time about eight seconds.

How can I make the action like crane object?
Or another method like that?

Thanks.

I think for showing the gripper you could try what the Animation Creator does and set a loading time for the actual time, animation needs.
Maybe you need another shape or a cube for showing the gripper.

Further you should set the maximum number of travelers at a node to 1, this way the Taskexecuters shouldn´t overtake. Spacing rule should work furthermore.

Hi,

if you want a fast test, try a transporter traveling on a network. Each networknode has a z position value e.g. 4. Use the pick- and place-offset tasks to make the lifting independent from traveling. If the behaviour suits you, change the shape of the transporter and build some glboxes to show the lifting beam structure.

Tryed out a bit and setting all connections in travelpath to non-passing should disable overtaking. But I couldn´t find out why your Taskexecuter stops and why they drive through eachother...

Hi, Jorg. Thank you.
But the test model uses the network node object not conveyor. The conveyor over the AGV is only for visual. And Do you mean 'pick and place offset tasks' is "TASK SEQUENCE" when arriving the loading and unloading position?

And what looks like the lifting beam structure is only "rubber belt" like the chain of Crane object.

What's important is not 'beam structure' or 'rubber belt' but how to make the lifter and it up or down to grip the item.

Should I use 'visual animation creator' or 'kinematics command' in the trigger event?

I want to hear all expertised guide.

Thanks.

I made another test model again without using the vusual container to display network and AGVs.

But the model's AGVs also stopped on traveling.

And they took over though setting the non-passing and only one traveller on the network node.

What's the problem in the model?
Or it is flexsim's bug?

Hi, just found out that the point is, that both TE´s meet at one Networknode. As you can see in the first container in the attached model, overtaking on the travelpath is possible.
In the second container overtaking is not possible, because maximum number of travelers at a networknode is 1. And in the third container I use a TrafficControl to make the second operator waiting at a defined point.
