How do you calculate the theoretical packs per minute of a machineby Mrlad1984 Tags: machine, minute, packs, theoretical

I am wanting to calculate the theoretical packs per minute of a machine. The machine pushes packs into a indexing conveyor and is transported along the conveyor and is cross pushed on to an exit conveyor.
Each pack is 144 mm long and the machine indexes every 0.65s plus a 1.4 second dwell for a cross push on an exit conveyor. The length of the conveyor is 1.4m. What is the methodology of calculating the packs per minute?

Welcome.
If it takes 0.65 sec to step one index and 1.4 sec to unload, then the cycle time is 0.65 + 1.4 = 2.05 sec. That gives 60 / 2.05 = 29.27 packs per minute. But the answer will depend on your definition of index time. To give a better answer we need a better description of the timing, overlap and probabilities of unloading. Please give more details, and ask more questions if this has not answered your question.
