How to create individual alignments for each part in pallet?

[[Bl...]]

Hello all,

 

Imagine there are the 5 exact same parts on a pallet with the exception of their heights. Does anyone know how I would be able to take an alignment for each one so that the machine will know where to go without any input? I understand there is the "LOS position" feature in autorun, but I am unsure how to set it up. Any help will be appreciated.

For this we ended up with storing part alignment in all positions ( storing with name "p1", "p2", ... ) and then linking those alignments with position of pallet.

Unfortunatelly this is the only way - you can not define pallete anything other than X and Y

Martin,

 

Thank you for the answer. Is there any way you can give me a detailed account on how you stored all your part alignments?

 

The parts we run are all over the place. One part may be super short, another bent to the right. What we're trying to achieve is a manual alignment on each part in the program before we switch to autorun (so that way the probe doesn't crash performing the base alignment on the next part). Is this still achievable?

Could you please share a photo or a sketch of your setup? I suspect the solution might be very simple.

I would imagine a standard Pallet Alignment would take care of this for you, but here is the Knowledge Base article for what you are looking for.

 posted - you can focus on irregular pallet "LOS POS"

And for those alignments: i've opened measuring program -> placed a part into nest1 -> opened alignment window ( base / start ) -> renamed as "ORIGINAL NAME-p1" and run manual alignment.
Repeat for all positions.

For 3 parts

 I attached the photo below, it's very basic but that's it in photo form. Each part can be at varying heights with different bend angles in them.

 How do you get back to the original alignment after you run "ORIGINAL NAME-p1" / "ORIGINAL NAME-p2" / "ORIGINAL NAME-p3" (and execute manual run for each)? Do you just rename the base alignment in the (base / start) window?

[[Ma...]]

Yes, i just normally open definition of base/start alignment, rename it and perform manual via button.

But i doubt it will be the best option.
According to your drawing i would stick to regular pallet and used start alignment with long search distance to avoid collision. Or do such start alignment to catch those variations.

As you could see i have 3 part directly above and measuring it with long T probe.

Yes, I see the photo you posted. It makes sense what you're saying. The issue with the search distance is that the part may be leaning at a different angle for the next part. The probe will end up missing it entirely or run right into it because there's so much variation for every individual part. 

 

Will I have to do something similar with the start alignment? Create "ORIGINAL NAME-p1" / "ORIGINAL NAME-p2" / "ORIGINAL NAME-p3", but instead do the execute manual run after a start alignment?

How much variance is there?

Are those different parts or just deformed ones?

I have done it on start alignment, just add into it's name a position number or any identification and run that manually to store it's location.

There's a good bit of variation from part to part. They're the same part number, but the machine forms them differently each time. These aren't machined parts, they're formed using water.

In my understanding, 'a good bit of variation' from part to part could mean a fractions of an inch. Am I right with this assumption, or could you please be a bit more specific?
