Packo Rabanne gets private tutoring
12.4.2023
Our packaging machines make mistakes too. But last year there were so many wrong deliveries that we had to intervene. Our newest packaging machine, Packo Rabanne, was sent to detention.
It was our After Sales Service who first noticed that something was wrong. The autumn before last, the team informed us that they were registering an above-average number of returns – but only for orders processed by the packaging machines. Now, you’d think robots don’t make mistakes. But they do. This could be, for example, because a product gets mixed up somewhere in the machine.
Up to this point, however, there had been only a few incorrect deliveries. Suddenly, we were confronted with a massive increase. Compared to the many packages we send out, this is a small fraction. Even so, mistakes like this cost us a lot of money.
Shortly before we noticed the flood of errors, we started up the fourth packaging machine. After Packy McPackface, Sir Packsalot and Packie Chan, Packo Rabanne joined the team in October 2021. The obvious conclusion was that our youngster Packo was out of line and responsible for the faulty parcels. After a thorough investigation, we found that Packo was indeed the culprit.
Find the fault
Thanks to our video analysis, we also noticed that the error often happened when two products passed through the scanner at the same time. There should, in fact, be a distance of 15 cm between products. We were able to quickly eliminate this source of error by monitoring this distance.
A good schooling for Packo
In addition, we trained our packing employees. Orders consisting of multiple products that go through the packaging machines are particularly prone to errors. They’ve got to be sturdily bundled so they don’t end up rolling around on the conveyor belt. We shared our findings with the manufacturer of the packaging machine, who fixed several bugs in the software. and used our feedback to revamp Packo, resulting in fewer incorrect deliveries.
Detention paid off for Packo. He’s making much fewer mistakes now. Our goal was to have him generate no more than 400 incorrect parcels per million parcels shipped. That would be an error rate of 0.04%. In November 2022, we reached this figure – right in time for the Christmas rush. And in the months since, Packo’s got even better. Bravo!
