Arizona Palletizer: How Arizona Manufacturers Automate End-of-Line Case Stacking

From Phoenix metro food and beverage plants to packaging operations in Tucson and across the Valley, many small and mid-size Arizona manufacturers share the same line-end picture: cases come off the packer steadily, and a person stacks every one of them by hand, all shift. The work is repetitive, the top layers are placed high, and when that person is out, the whole line feels it. Here is the local fit check Arizona plant and operations managers can run before automating that job.

Check 1: Start with the five sizing numbers, not a brochure rate

Every good palletizer decision starts with the same five numbers we set out in Pallet Patterns and Case Sizing: case length × width × height, heaviest sealed-case weight, sustained cases per minute, cases per pallet, and pallet size. Collect them for every SKU that will run on the cell, not just the best seller. Arizona plants often run a mix — a light retail case most of the week and a heavier club or bulk case on other days — and the cell must be sized to the heaviest case in scope.

Our base rental cell handles cases up to 20 kg (44 lb), with robot reach up to 1,880 mm. If your heaviest case is above that, or your stacking height is above the standard setup, say so at the first walkthrough. Dorna’s cobot cells can be customized for cases up to 50 kg and for stacking heights above 8 ft, and custom systems are priced after a free walkthrough, an initial estimate and a custom design — that is a different path from the base cell, and it is better settled before anyone promises a fit.

Check 2: Size to the sustained rate your line actually holds

Do not size to a short peak rate from a good ten minutes. Size to the sustained cases per minute your line holds over a full run, including pallet exchanges, stretch-wrapper stops, label checks and SKU changeovers. That sustained number, matched against cases per pallet, tells you how often a pallet fills, how often someone must exchange it, and how much hand lifting the cell will actually remove.

For the cycle-time thinking behind that, see How Many Cases Per Minute Can a Cobot Palletizer Handle? — and bring your sustained number, not your peak, to the walkthrough.

Check 3: Confirm footprint, power and air at your actual line end

Many Arizona plants grew line by line, so the end of the line is rarely a large empty area. A cobot cell helps here because it is compact: a typical footprint is about 3,000 × 3,000 mm, with two pallet stations of 1,100 × 1,100 mm, a conveyor infeed at the top centre, and a safety light curtain on the open side. Each cell needs 110 V power, max 15 A, plus a compressed-air connection — utilities most plants can provide at the line end without a major project.

Place the cell where sealed cases already travel, after the case packer or sealer, without blocking forklift routes, access ways or emergency exits. Remember the layout rule too: a single fixed cobot places to its left and right only, so two pallet stations are the standard layout; serving four pallet positions takes a linear rail or a second robot. A clear photo of your line end, with rough dimensions, is the fastest way to confirm all of this before a site visit. Our Phoenix palletizer rental page and Tucson page cover the local rental offer in more detail.

Check 4: Settle safety and patterns before install day

Collaborative does not mean “no assessment needed.” Work through the risk assessment for your plant: who works near the cell, how pallets are exchanged, and whether safety guides or a cage are needed for your layout or plant rules. Guides and a cage are options fitted when needed; the base offer is pitched without them, and the typical layout includes a safety light curtain on the open side. Our guide Are Cobot Palletizers Safe? walks through that assessment step by step.

Patterns matter just as much. Each case format gets a stored pallet pattern — a recipe — so layers are square, stable and repeatable for stretch-wrapping, and a changeover becomes selecting the right recipe and confirming the first case. Decide in advance who selects recipes, how a part-finished pallet from the previous SKU is handled, and where finished pallets for different products are staged so loads do not get mixed.

Check 5: Plan the Arizona install as a short, personal project

Dorna is based in Arizona, and delivery is typically 3–4 weeks. The robot ships on a wooden pallet; receiving delivery and providing a pallet jack on site, at a delivery time coordinated in advance, are the customer’s responsibility. Siamak personally attends installation, start-up, training and pallet-pattern recipe creation, so the cell is tuned to your cases and patterns on your floor, not left as a crate and a manual.

Palletizer Installation: What to Expect covers the sequence in full: sizing confirmation, site readiness, delivery, on-site install and start-up, recipes and operator training, and the common delays to avoid. Billing and the rental term start at installation and start-up — not at order, and not while the robot is in transit.

Why Arizona plants often rent the first cell

For a first automation step, the question is rarely only “does it work?” It is also “what happens if our mix, rate or layout changes?” A palletizer rental at $1,999/month with zero upfront, installation and maintenance included, lets an Arizona plant prove the cell on its heaviest case, its real sustained rate and its real changeovers, without a large upfront purchase. That $1,999/month is the base cobot palletizer cell price; quarterly, semi-annual and annual prepay options are also available at the start of each period, as set out on the rental page.

Industry-specific checks are also available for food plants, beverage and bottling plants and pharma and nutraceutical plants — all common Arizona manufacturing types.

The bottom line

For an Arizona manufacturer, the fit check is five questions: Have you listed every case format and weighed the heaviest sealed case? Do you know your sustained cases per minute, not just your peak? Is about 3,000 × 3,000 mm, 110 V power and compressed air available at the line end without blocking forklift routes? Have you settled the safety assessment, patterns and recipe changeover rule? And are you ready to receive the robot on a pallet, with a pallet jack, in 3–4 weeks? Answer those, and an Arizona palletizer stops being a big capital gamble and becomes a practical, local next step: consistent pallets, without hand-stacking every case.
