Tool to know number of items on each line production

Tool to know number of items on each line production


I work in a dining room table manufacturing company. We have two lines in our paint shop. I would like to set up an indicator to know the number of items on each production line to allow for a balanced supply of tables to be painted. Currently there is no way to know this, so it happens that for example line 2 can be filled to its full length while there are empty spaces on line 1. I don't know what tool could count the number of panels on which the tables are placed between the first paint booth and before the last lacquer booth on the production line (I had vaguely thought of sensors). With this indicator, we would know if we need to send more painting tables on line 1 or line 2.
If you have any ideas or solutions, I'm interested.

Thanks to you

RE: Tool to know number of items on each line production

Large numeric displays above the input side, use simple sensors to count pieces in minus pieces out.
A very simple little controller to do the math and drive the display.
You could use this to signal when you need more (too few) and when you need less.

RE: Tool to know number of items on each line production

You have all sorts of options.
Ranging from simple proximity switches to using RFID tags on them.
I have even seen this done with manual switches at the load and unload stations.
Just depends how fancy you want to get.
When you have too few you could make the number green and flashing, static amber numbers when the count is fine, and flashing red when it is too high.
You don't need to display a number either.
If the count on a line drops too low you could display 'MORE' and if rises too high display 'STOP', or some such wording.
Then no one would have to ask what the right number was.
