I am selecting tooling for 154 planned closed-carton transfers between packing stations with a UR5e. The supplier demonstrated a smooth carton. Our lightweight packed cartons vary in seams, print and board surface. What evidence would make the tooling choice defensible for those actual cartons?
Send a small, identified selection spanning the awkward surfaces, not just the neatest box from stores. The demonstration carton has already had its audition.
I'd settle the required handling conditions before calling a selection representative. Board surface matters, but so do the packed condition and the way the carton arrives. Otherwise a successful sample demonstration can still leave the supplier and buyer describing different work.
Include loss-of-hold handling in the application review. Detection and the appropriate response need assessing; a successful lift video cannot establish those protections.
Our picture review once gave samples confident labels before anyone judged the actual objects. I would identify the physical cartons and photograph them, but keep the cartons available. The pictures will not tell the toolmaker everything about the board.
A cheap starting point is agreeing the contact regions on those physical samples. That is not a handling approval. It can stop you commissioning a larger trial around a region you cannot consistently present.
Nina, would you show the full release position as well? I worry about a tool that holds beautifully and then has nowhere to get out. There may also be neighbouring cartons by the time it withdraws.
They should, Amara. Otherwise the next quotation can quietly describe a different arrangement from the one everybody watched. Jane also needs the unsuccessful sample cases, not merely a highlights reel.
I have asked for a proposed sample selection and trial conditions, including contact regions, receiving occupancy and hold-loss response. The supplier has not yet agreed that scope. I am not accepting the smooth-carton clip as our application evidence.
Ask them to state which variations the proposed selection does not cover. You may choose to restrict the job initially, but that needs an operating restriction people can recognise, not a buried assumption that all cartons behave like the chosen samples.
