For a multi-client third-party logistics provider, robotic container unloading needs a record of which carton profiles have been assessed and what changes require another review. One client’s successful unload does not establish eligibility for another client’s packaging, even when both describe the goods as cardboard boxes.
The 3PL project qualification guide covers whether unloading is a suitable first investment. This guide covers the operational decision that follows: how to keep different client freight profiles, changes and exceptions traceable once shared equipment is being planned or used.
Download the profile-change log to connect each change to its evidence, decision owner and affected loads. It is a blank planning tool, not a record of verified KRONA customer freight.
Register the handling profile as well as the product
A stock-keeping unit (SKU) identifies a product variant. It may not describe the filled carton, contact face, tape pattern or load-wall arrangement the unloading system encounters. Keep those handling details in a versioned profile linked to the client and SKU.
Record:
- client and product identifiers, plus the carton-profile version;
- filled dimensions, mass range and contents distribution;
- board, sealing, labels and the faces normally accessible in the container;
- transported condition and known damage patterns;
- loading pattern, intended extraction and receiving destination;
- assessment evidence, its conditions and the person owning the decision.
Use status names with a clear meaning: not assessed, assessment pending, verified within recorded conditions and outside the agreed envelope. Do not label a profile verified because it resembles one that passed elsewhere. The carton-gripper guide explains why contact and filled-package condition matter.
Decide which changes need reassessment
| Observed change | Evidence to collect | Decision to record |
|---|---|---|
| New board, tape or label placement | Transported sample and accessible-face photographs | Whether the previous contact assessment still applies |
| Changed contents or filled mass | Weighed samples and distribution of contents | Whether load and retention evidence covers the change |
| Different loading pattern | Images from relevant stages of the container | Whether access and extraction conditions remain covered |
| Different receiver or destination | Revised handoff drawing and required presentation | Whether transfer, routing and receiving checks need repeating |
| Recurring damage or more assistance | Load references, observations and event times | Whether the issue affects one batch or the profile definition |
The table is a review process, not a universal approval rule. The supplier and responsible site team need to decide the assessment required for the actual system. Retain the previous result with its version instead of silently rewriting it to cover new freight.
Work through a two-client change example
The following is a hypothetical planning example. Counts and schedules illustrate record keeping; they are not measured KRONA results or proof that the named packaging is suitable.
Client A expects 600 cartons on a Monday delivery using profile A-03. A recorded assessment exists for its earlier packaging, but the client has now changed the tape position. The warehouse records change A-04 as pending assessment and keeps that load outside the previously verified volume until the responsible team decides what evidence is needed.
Client B expects 400 cartons using profile B-02, with an existing assessment covering the stated freight conditions. The receiving team separately confirms that B’s scanning destination is available during its slot. That receiver confirmation is not part of A’s packaging assessment.
The two loads contain 1,000 expected cartons. Only the 400 associated with B-02 are included in provisionally covered volume for this scheduling exercise; A’s 600 remain pending. That is 40% of expected cartons, not a forecast of how many cartons a robot will successfully unload.
After reviewing A-04, the decision owner records the result, its conditions and the affected delivery references. If the change is accepted, future coverage calculations can use the new version. The warehouse retains the pending period and any alternative unloading arrangement in the history.
Schedule assessed loads against the actual shared resources
Eligible freight still needs an available dock, receiving destination and assigned exception team. Reserve those resources together; the existence of an idle robot elsewhere does not establish an available receiving route.
Hypothetical shared-dock schedule: Client B reserves 08:00–10:00. Allow a separately estimated 20-minute changeover before Client A’s reviewed load starts at 10:20. If A’s slot lasts 90 minutes, it ends at 11:50. These are planning assumptions for complete dock use, not box-rate calculations.
A request for Client A to start at 09:30 overlaps B’s slot by 30 minutes before changeover is considered. Resolve the resource conflict through the site’s scheduling process; do not allocate the same dock and receiving capacity to both clients at once.
Use the line-capacity worksheet to test receiving interruptions and reserve capacity for pallet removal, scanning and other clients. Record the practical fallback if the confirmed slot becomes unavailable.
Keep carton, pallet and transport changes traceable
A carton-profile approval does not approve every finished pallet or movement route. Give the receiving record separate references for the carton profile, intended pallet contents and destination, and the equipment configuration used for pallet transport.
A client can retain the same cartons while changing pallet size, maximum stack height, wrapping, collection point or put-away destination. Record the changed requirement and assign a review owner before applying it to the next shift. Link the finished-pallet identity to the client so a common staging lane does not lose stock ownership.
For an integrated KRONA flow, agree when the palletizing process releases the load and when the KRONA forklift or AGV system confirms collection and delivery. Preserve a hold for missing inspection or stock data even if the vehicle is ready. The mixed-case software requirements explain how confirmed contents and pending moves remain distinct.
Assign the client, warehouse and supplier decisions
The client can notify the warehouse of packaging changes and provide samples. The warehouse can identify the affected arrivals, receiving requirements and operational owners. The supplier can assess whether the revised handling conditions remain within the proposed equipment’s envelope. Record the actual responsibilities in the project agreement.
Give each pending change an owner and a due date. If the warehouse receives changed freight before a decision exists, use the agreed alternative handling or review process. A product purchase order does not authorise an undocumented robot configuration change.
Track coverage and assistance by client
Keep the denominator beside every percentage. “Eligible coverage” might mean assessed carton count divided by expected carton count; a trial result might mean completed accepted cartons divided by attempted cartons. These answer different questions.
For each client, retain expected cartons, assessed-profile cartons, attempted handling, completed accepted cartons, exceptions and operator minutes. Record repeat attempts without counting the same carton twice in receiving totals. Split elapsed dock occupancy from active robot operation.
Compare successive periods only when the profile definitions and measurement boundaries are consistent. A rise in assistance following a packaging change is a reason to investigate the associated evidence; the log alone does not establish the cause.
Keep a change log that the next shift can use
The CSV change log includes client, profile version, observed change, affected delivery, status, evidence, decision owner and receiving implications. Keep private client records in your warehouse systems; send only information you are authorised to share in a supplier assessment.
For each load, use the recurring container-unloading checklist to connect the current approved profile with the actual receiving record.
