The robot picking them from the table averaged a 3 second pick to pick, the robot placing the parts averaged 3.2 seconds place to place.
We have a cell feeding a punch press, we run just under 5 seconds cycle time (get part from feeder, load die, pull pressed part out and place on outbound conveyor) and the press has a 800-1000 ms cycle time so we run somewhere between 5.6 to 5.8 seconds per part, 20+ hours per day.
We have a number of cells that run in the 6-11 second range per part. One of them that processes 4 parts every 42 seconds has produced parts for 23.9 hours in a single day. It generally puts in 140-150 hours a week, usually only going down when the injection mold is not running. I’m that time it picks the part up, uses a labeling machine to accurately apply a label and packages the part for shipment to the OEM.
These are just just a few examples of cells we have at customer sites.
The applications where we are having human robot cooperation the cycle times are much slower and the tasks can be complex or just long. One example is the human takes about 30 seconds to fixture 5 pieces and then the robot installs over 100 rivets, total cycle time is just under 9 minutes. Each rivet though averages less than 6 seconds taking away a mundane task from the human and performing that task faster than the human does on average by a considerable amount.
