Worker to perform Services

Legend

Hi all,

 

I like to know how I can program setup/maintenance services on SingleProcs of the workcell in my model.

In normal run time the product moves through the workstations and end in a stocking store.

I attach a small example model to do the exercise.

 

Ex:

Each machine (SingelProc) is running for x hours,

It is stopped and the worker is called to do the required maintenance (Tool changes, cleanings etc...). 

Then it can restart for the next x hours.

And so it continues...

 

Kind regards

Marco

in this cases you need to deactivate availability in the failure profile. Now you can set the failure duration (e.g. 30 minutes) and the distance between end of the failure and start of the next failure (e.g. 4 hours). To call a worker for maintenance you need to activate the failure importer (Importer Tab of the station). Here you can set also a special service for maintenance

Hi Steffen,

 

referring to page 108, 109 of your manual, I setup my example to have:

Start: 4 hrs

Interval: 4 hrs

Duration: 0.3hrs

This is the first choice how to use it and basically what I need.

What you recommend blow comes next.

 

Starting the simulation, the parts do not leave the Workstation1 (SingleProc) until the operator comes to the workstation (5 sec).

 

 

Kind regards

Marco

 

PS: I need to zip the attachments, other the system does not allow me to attach the model.

it is only a matter of animation; look at the clock in the eventController. Your source has no interval, so the source will create a lot of events at the time 0, if the buffer is filled, the clock starts counting and then starts your worker (he will need some seconds). For maintenance you need also to activate the failure profile

Hi Steffen,

 

So I change the source to 2min part release time..

I change the failure (setup) times to: 4hrs Start; 4 hrs Interval; 30min Duration. This is basically a good start for what we have in our real world.

 

The worker still does not wait for the Start time to have elapsed. The failure 'Setup' is active, or do I need any other option selection. I guess by ' failure profile' you mean the 'Active' option checkbox.

 

Kind regards

Marco

the worker needs to stay at the machine also for processing or only for maintenance?

The setup technician will serve 3 workstations to do maintenance work after the machine run for ex: 4hrs.

He will sit at this spot to wait any required maintenance.

 

Now he will step to the machine, stop it and perform a number of tasks like used tool change, review calibration etc....

Once finished he starts the machine and returns to his spot.

 

An so it continues, the maintenace schedule will define to which machine he will go.

The machine usage will also determinate the setup technician work load.

 

The aim of the simulation exercise is to check the usage of this setup technician in the model running with the real times.

Is one worker enough ? or to they need to plan another worker  in the real world.

My main model is supposed to give answer to the questions on how the production need to be organized.

then you need to deactivate the importer for processing (Bearbeitung), otherwise the machine will work only togheter with the worker

OK, this work now, the parts are flowing through the line.

 

However the worker does not move out of the pool to perform any service.

 

The workstation1 (SingleProc) does not have any reference to the service anymore. The exit is cyclic which is right.

Only the workplace have the reference to the worker/service.

 

* Adding a method in the Set-up section of the control panel does not call this code.

 

* The 'Set-up' panel in the Importer only allow me to select common resources. I guess as the importer is generally non-actived, the setup does not occur.

 

So there is still something missing.....

you need to activate the failure Importer
