Chain conveyor assembly

[Anonymous]

Hi,

first of, we build automation equipment. Almost every machine is custom build with an indexing Rollerchain conveyor assembly. The assembly usually consist of 4 chain sprockets. Chain size and chain link attachments vary.

With what I have seen on cbliss.com, there must be a way to create the 4 sprockets with the appropriate center points, P.D., wrap the custom chain configuration around it and constrain them.

At this point I'm not sure how to start the assembly.
We do have the sprockets drawn, chain section pattern created and location of the theoretical sprocket center points.

For the future, we would like to create an iPart assembly, where you specify location of sprocket centers, pitch diameter of sprockets, chain size and desired pattern.

Here is my question for all you Inventor users out there:

Is the above described iPart assembly realistic/feasible?
With the correct constrains, could the chain assembly be "indexed" around the sprockets?
Any hints/tricks/suggestions on how to get started?

Your help and ideas are greatly appreciated !
Please email me, if you are interested in looking at the "ACAD2k2 layout" and .ipt components we have to this point.

Thank you,

First of all, moving chain around a sprocket correctly is, for all intents and
purposes, impossible at this point. I have a method that allows harmonic motion,
but nothing like you want. (Believe me, I've tried)
Second, right now there is no such thing as Assembly iParts. You can drive all
the parameters using a spreadsheet though.
Example: Did you use this chain for Parts (not iParts):
http://www.cbliss.com/inventor/Parts/RollerChain.zip?

With this, it will automatically create the chain at the correct C.D., sprocket
diameter and pitch. You can then constrain the sprockets to the middle plane of
chain loop, C/L of one of arcs, and c/l of one of the chain rollers. If you need
a configuration where 1 chain goes around more that 2 sprockets, you will have
to just constrain the chain rollers (used from iPart) to the individual sprocket
teeth (just the ones that are completely in the teeth)

There currently is no iAssemblies. If the chain and sprockets etc can all be one part
then you may be able to make a iPart of what you want??

Not sure if you have the budget, but you may want to look into a
configurator that works along with IV to do what you want.
Checkout www.configureone.com and www.stormmaker.com

Dave,

Thanks for your help and input. I was hoping to hear: Yeah, we have done
that, here is the Macro !

No, we didn't use (your link) for parts. We created our own components.
I tried using the one you mentioned. I can't get the excel notes
to update the drawing.

I enter:

#40 chain
72 teeth
50 teeth
127" center-to-center

I get the following error: WARNING, Cell B54 MUST be 2 or Greater, adjust
above B54 =

How do get rid of the error?
And how do I get the table to update the ipt file?

Thanks,

Peter

Sean Dotson and Charles Bliss created that chain spreadsheet, so you will have
to ask them. It works for me all the time.
