It is the current thing for the small stuff.
I have seen fasteners, safety stuff, WD40, first aid kits, you name it.
They are tied in to the company's shop floor computer system so that when you use your ID to get something it knows what job number you are signed in for and therefor where to charge the withdrawal to.
Having had to manage one of these units if the mechanics work with it correctly and have care when removing small bits and pieces that are not bagged ie rivets and nuts and such it works fine. If they do not it is a nightmare every time a piece falls down it lands on the table supporting the rotating assembly and a lot of time jams under the wheels supporting the carousel . If the computer or one of the sensors fail it did not have a manual mode. In the case of small parts if the mechanics do not tell it how many they took out the inventory count will always be wrong.. Mind you most of the faults are user driven but in a shop full of mechanics over 40 per shift you get the idea.
we had one at work for PPE so the drivers could get new gloves/goggles /resp cartridges with no one in the shop , and it kept track of who was hording them too . cut operations costs in half , we also had it set up for light bulbs for the trucks too . saved mechanics time going into the tool room to get them . plus we did n't have a mechanic on duty to get them one .
We started keeping all of our cutting inserts in them, and have expanded to a lot of out other small tooling.
Recently added over 1,000 small electronic components that production techs used to come an get on a "self serve" basis and not check out of the inventory (or put the wrong one in a machine). Really cuts down on costs.
I've never seen one of those, but I did work in a shop with vendor managed inventory. A cutting tool vendor kept a locked cabinet stocked with tools, and we didn't pay for an item until it was taken out of the cabinet. PITA for the guy with the key, but it was better than either running to the store, or paying for a bunch of inventory. I see this as the next step.
They are vendor stocked.
They have a cell phone in them to call the vendor with their stock levels.
The shop gets charged at the end of the month with an itemized invoice showing what went was taken out by who.
These are great, we tried to switch over to Fastenal on our PPE and have them stock it in a vending machine. Especially for gloves and glasses. Fastenal said this will decrease our inventory costs by 50% in the first 6 months just because when people have to scan their badge they are less likely to take a new pair of gloves off the shelf everyday or a new pair of glasses every week.
We just got approval to get these in our shop.. one will have welding supplies, and one with mechanics supplies.. i like the idea of the automated inventory management. .
