How do I calculate payback on a case packer or palletizer?

Use the Case Packer ROI or Palletizer Payback calculator. Enter equipment and install cost, the labor headcount displaced, and any throughput gain in cases per minute. The tools return payback in months by dividing capital by monthly labor and rate savings. Most end-of-line projects justifying two or more operators per shift land inside 18 to 36 months; pair with End-of-Line System ROI for the full line view.

How do I find the bottleneck on a packaging line?

Run each station through Labeler Throughput, Carton Sealer Throughput, Case Erector Capacity, and Palletizing Cycle Time, then feed the rates into Packaging Line Balance and End-of-Line Bottleneck. The slowest sustainable station sets line speed, and the bottleneck calculator flags it plus the starve-and-block losses on faster stations upstream and down. This tells you which station to upgrade first for real throughput gain.

What OEE should I expect from an automated end-of-line system?

Use the Packaging Automation OEE calculator, which multiplies availability, performance, and quality. Well-run end-of-line systems typically run 75% to 85% OEE; below 65% usually points to changeover or minor-stop losses. Break the number down with Packaging Changeover Time and Label Applicator Uptime to see whether availability or performance is the constraint, then target the larger loss bucket.

How much labor can end-of-line automation actually save?

Quantify it with End-of-Line Labor Savings and Case Packing Labor Cost. Enter current operators per shift, shifts per day, and fully loaded labor rate, then the automated staffing level. The output gives annual labor savings and the headcount delta that drives your ROI. Manual case packing and palletizing lines often carry two to four operators per shift, which is the largest single lever in most justifications.

How do I size a palletizer to keep up with my line?

Start with your upstream case rate in cases per minute, then run Palletizing Cycle Time and Robotic Palletizing Utilization to confirm the palletizer clears that rate with margin. Use Pallet Pattern Efficiency to check that the layer pattern fits the cases without wasted footprint. Aim to leave 10 to 20% headroom so the palletizer never becomes the bottleneck during peak or catch-up running.

How do changeovers affect end-of-line throughput?

Changeovers cut directly into availability and therefore OEE. Use Packaging Changeover Time with Line Clearance Workload to total the minutes lost per SKU switch, then see the effect in Packaging Automation OEE. Lines running many short runs lose far more to changeover than to slow cycle rates, so on high-mix operations reducing changeover often beats buying faster equipment for improving daily case output.

Packaging Automation & End-of-Line Systems calculators

This category covers the throughput, staffing, and payback math for end-of-line packaging automation: case packing, palletizing, labeling, coding, and stretch wrap. It is built for packaging engineers, plant managers, and integrators who need to size a line and justify capital before the equipment order is placed.

Best calculators in this category

Case Packer ROI: Estimate the payback period for an automated case packer by comparing the installed project cost against the labor, rework, and throughput savings it delivers each year.
Palletizer Payback: Estimate the payback period for a robotic or conventional palletizer by weighing the installed cost against the labor and damage savings from automated palletizing.
Labeler Throughput: Estimate the good labeled output of a labeling line per shift from application rate, available run time, uptime, and first-pass label quality.
Case Erector Capacity: Estimate how many erected and sealed cases a case erector can supply per shift from its forming rate, run time, uptime, and clean-erect quality.
Shrink Wrapper Cost: Estimate the total film and operating cost to shrink wrap a production run from packs wrapped, film cost per pack, applicable share, and fixed setup cost.
End-of-Line Labor Time: Estimate the manual labor time a run takes at end of line from the units to handle, the manual handling rate, and an allowance for setup and breaks.
Packaging Line Balance: Compare a packaging station rate against the line target rate to see how well balanced the line is and where it is starved or backed up.
Palletizing Cycle Time: Estimate how long it takes to palletize a run from the cases to stack, the palletizing rate, and an allowance for pallet changes and setup.
Robotic Palletizing Utilization: Calculate how much of the available production time a palletizing robot is actually stacking, and the gap to your utilization target.
Carton Sealer Throughput: Estimate the good sealed cartons a carton sealer can deliver per shift from its sealing rate, run time, uptime, and seal quality.
Checkweigher Reject Cost: Estimate the cost of packs rejected at the checkweigher from reject count, value per rejected pack, scrap share, and fixed recheck cost.
Label Applicator Run Time: Estimate the run time a labeling job needs from the units to label, the application rate, and an allowance for reel changes and setup.
