bit shift register

[SirTrollsalot]

Hi all,

I am working with TI.

I was told to get a utilization percentage. I have wood coming from a dryer, and when there are open spots on this conveyor, a refeeder will put wood in those open spots and go down the conveyor.

I was told to get a utilization percentage. like are we using 50% of available space on the conveyor? 75%?

I have switches available on the conveyor (LS's, maybe others) that will let me count how much wood is on the conveyor. I can also find out how much wood comes from the refeeder with a certain coil that turns on for each piece of wood.

I was thinking of using a bit shift register in order to look at how much space we have available.

Anything helps. I know this isn't very specific. I'm very new to this and that's kind of why it isn't specific.

I dont know TI
however using a Shift register is the right way.

If your pieces are the same size then it will be simple math.
In the example below. I used 18" pieces over a 10' section of conveyor.
1. 3x18=54 54/120= .45
2. 4x18=72 72/120= .60
3. 5x18=90 90/120= .75

Or the Accumalation of Time your switch is Blocked Divided by Conveyor Speed. If conveyor speed is 60 ft per minute and your blocked time is
1. 27sec then 27/60= .45
2. 36sec then 36/60= .60
3. 45sec then 45/60= .75

Now to do this in a plc remember to multiply your Accumaltion by 100 to remove the decimal point. So (Accumation time x 100)/60

The benefits of a metric system.
All measurements are in factors of 10
