What are case conveyor systems, and how are they different from buying conveyor sections?
Case conveyor systems, like other industrial conveyor systems, are engineered networks of conveyors, transfers, accumulation zones, routing devices and controls that move packaged goods between automated processes in one specific plant. In TRFIntraflow, custom conveyor systems means custom layout, flow logic and interfaces, not one-off hardware: it uses standard, repeatable modules, and the engineering goes into arranging and controlling them around your production flow.
This is intralogistics at the end of the line: once a product is packed, the case has to be transported, accumulated, merged, diverted, sorted, elevated and delivered to a palletizer or a warehouse interface, at the rate of the lines. A case conveyor bought section by section tends to leave gaps: cases pushed by hand at transfers, lines that stop when the palletizer pauses, and controls that do not talk to each other.
| Decision factor | Engineered system (TRFIntraflow) | Sections from several suppliers |
|---|---|---|
| Responsibility | One partner is accountable for the agreed project scope, from system design through startup | Each supplier answers for its own section |
| Flow logic | Accumulation, merges and routing designed together for the real line rates | Buffers and merges sized section by section |
| Controls | One control concept with sensors, PLC, HMI and machine communication | Several control concepts that must be made to work together |
| Machine interfaces | Defined in the same engineering as the conveyors | Defined separately by each supplier |
| Startup | One commissioning team for the conveyors and their interfaces | Several teams, coordinated by the plant |
A turnkey system does not mean giving up standard hardware. TRFIntraflow keeps repeatable engineering and consistent parts, and adds one partner accountable for the agreed project scope.
Powered Roller Conveying, Engineered Into the System
Powered roller conveyors are one of the standard TRFIntraflow modules, alongside belt and modular belt conveying, transfers, accumulation, routing and elevation. Accumulating conveyor systems, with zero-pressure accumulation, hold cases in a buffer so the packer and the palletizer do not have to run at the same instant. TRF engineers them into a complete material-flow system with controls and palletizer interfaces, from layout to startup, rather than supplying individual conveyor sections.
What does an industrial conveyor system do on a production line?
An industrial conveyor system does four jobs at once: transport, flow management, routing and integration with the machines at both ends. Transport carries product between machines, across levels and through work areas. Flow management accumulates product when a downstream machine pauses, meters it so a robot picks at a steady rhythm and creates the gaps a scanner or diverter needs. Routing merges lines, diverts to a second lane, sorts by SKU or destination and rejects product that fails inspection. Integration links the conveyor to the machines through sensors, PLC and HMI, and barcode and vision interfaces.
A conveyor that only transports leaves the line exposed. If a palletizer pauses for a pallet change and there is no accumulation, the case packer upstream has to stop. Those are design questions, not catalog questions, which is why TRF engineers conveyor systems as part of the line. Each function solves a different flow problem:
- Accumulation builds a buffer so upstream equipment keeps running while a downstream machine pauses. Zero-pressure accumulation does the same in zones that stop and release individually, so units do not push against each other.
- Metering and gapping release units at a controlled rate and create space between them, which matters wherever a scanner, a diverter or a robot works.
- Merging brings two or more flows into one lane and depends on metering to avoid collisions.
- Diverting and sorting move units out of the main lane or route them by destination, usually from barcode or vision data, and a reject station removes flagged units without stopping the flow.
Which applications fit case conveyor systems?
TRFIntraflow fits plants where cases are bottlenecked or still moved by hand between automated processes. Typical applications:
- Case packer to palletizer, with accumulation that decouples the two machines, on a case conveyor or carton conveyor line.
- Multi-line consolidation, merging several packaging lines into one palletizing area or a centralized system such as TRFSpeed.
- Line balancing, with metering and buffers that help keep upstream equipment running during short downstream stops.
- Case routing and sorting, sending each SKU to the right palletizing position or warehouse interface.
- Reject handling, removing cases that fail code reading or inspection before palletizing.
- Level changes, with inclines, elevators, lowerators and vertical transfers where floor space is limited.
- Warehouse conveyor systems at the plant-to-warehouse boundary, exchanging data with the warehouse management system where the project requires it.
The platform serves mid-sized and large manufacturers in food processing, beverage, meat processing, frozen food, pet food, personal care, consumer packaged goods and industrial manufacturing, wherever several packaging or end-of-line processes need reliable case movement.
Is your line ready for case conveyor systems?
Your plant is a strong candidate for TRFIntraflow when most of these statements are true:
- Operators push, lift or straighten cases between machines.
- A short palletizer stop also stops the case packer upstream.
- Several packaging lines need to reach one palletizing area.
- Cases must be routed by SKU, code or destination.
- Aisles, forklift paths or existing equipment block the shortest route.
- Conveyors, case packers and palletizers run on controls that do not communicate.
Before quoting, TRF reviews five inputs with your team: the units conveyed (dimensions, weight range and bottom construction for each SKU), the line rates and number of lines, layout drawings with levels, columns, aisles and utilities, the points where the flow breaks today, and the case packers, palletizers, scanners and warehouse systems the conveyors must connect to.
How do you choose between TRFIntraflow, TRFCleanflow dry and TRFCleanflow washdown?
Choose by what is conveyed and how each zone is cleaned. Use TRFIntraflow when the item is a case, carton, tray, tote or other packaged unit moving between automation processes. Use TRFCleanflow when the item is exposed food or the conveyor sits in a hygienic or washdown zone: Dry fits industrialized foods with moderate, infrequent cleaning by vacuum, brushing and wipe-down, and Washdown fits animal protein and similar products with daily sanitation using chemicals, high pressure and high temperature. If a zone is mostly dry but sometimes cleaned wet, or sits next to a wet zone, TRF engineering reviews the sanitation procedure with your team before specifying the line.
| Criterion | TRFIntraflow | TRFCleanflow Dry | TRFCleanflow Washdown |
|---|---|---|---|
| What it moves | Packaged goods: cases, cartons, trays, totes | Exposed food in dry, low-moisture areas | Exposed food in wet, food-contact zones |
| Production zone | Secondary packaging and palletizing | Processing and primary packaging | Processing and primary packaging |
| Typical functions | Transport, accumulate, merge, divert, sort, elevate | Convey, incline, transfer, distribute, merge | Convey, incline, transfer, distribute, merge |
| Cleaning routine | Outside the exposed-food zone | Moderate, infrequent: vacuum, brushing, wipe-down | Daily sanitation with chemicals, high pressure, high temperature |
| Construction (design targets) | Heavy-duty industrial design for demanding production environments | 304 stainless steel, IP65 electrical baseline, optional enclosed or covered product path | 304 stainless steel with 316 optional, continuous welds, IP66 and IP69K electrical, NEMA 4X enclosure |
| Typical fit | Cases bottlenecked or moved by hand | Industrialized foods with moderate, infrequent cleaning | Animal protein and similar products with daily washdown |
| Main priority | Flow and scalability | Hygiene and uptime | Hygiene and uptime |
When a project crosses both environments, TRF combines the platforms as one coordinated material-flow system. With case packing and robotic palletizing, including TRFSubzero for areas below 32°F, from the same partner, the whole line is scoped as one end-of-line project, with the interfaces to stretch wrapping, labeling and warehouse systems defined in the same engineering. The Avon case study covers conveying, case handling and vertical transport.

Questions
Frequently asked questions
What Is Case Intralogistics?
Case intralogistics, the part of intralogistics that follows packaging, is the movement of packed cases, cartons, trays and totes inside a plant after packaging: transporting, accumulating, merging, diverting, sorting, elevating and delivering them to a palletizer or a warehouse interface at the rate of the lines. TRFIntraflow is the TRF platform for this job, from a single conveyor section to complete multi-line systems.
Is a Custom-Engineered Conveyor System More Reliable Than a Modular Off-the-Shelf One?
A custom-engineered conveyor system is usually more reliable in operation than off-the-shelf sections because accumulation, merges, routing and controls are designed together for the real line rates. Custom does not mean one-off hardware: TRFIntraflow uses standard, repeatable modules, and the engineering goes into arranging and controlling them around your flow, with heavy-duty industrial design for demanding production environments.
Can a Single Supplier Engineer, Build and Install My Entire Conveyor System?
A single supplier can engineer, build and install your entire conveyor system: TRF takes ownership of TRFIntraflow projects from system design and engineering to manufacturing, controls, assembly, installation and commissioning. One partner is accountable for the agreed project scope, which helps reduce the integration risk of combining sections and controls from several suppliers. The same team can integrate the case packers and palletizers at both ends.
How Much Do Custom Conveyor Systems Cost?
Custom conveyor systems cost what their scope requires: number of lines served, line rates, case size and weight, layout and floor space, the number of accumulation, routing and elevation points, and the interfaces with case packers, palletizers and warehouse systems. TRFIntraflow is always quoted as a complete engineered system, never as loose sections, after a flow review with your data.
Can Roller, Belt and Modular Belt Conveyors Be Combined in One System?
Roller, belt and modular belt conveyors can be combined in one system: TRFIntraflow uses all three with transfers, curves, turntables, accumulation, merges, diverts and elevation modules. TRF selects each module for the unit conveyed, the path it follows and the function of that segment, then connects them with sensors, PLC, HMI and machine communication under one control logic.
How Does Case Handling Automation Work in a Protein Plant?
Case handling automation in a protein plant moves sealed cases from packaging to palletizing on conveyors that accumulate, merge, route and elevate them without manual pushing or lifting. In the United States, protein plants buy TRF mainly for this conveying and end-of-line work: TRFIntraflow for packaged cases and TRFCleanflow for exposed product between processing and packaging.
How Is Conveyor Capacity Calculated for a Packaging Line?
Conveyor capacity for a packaging line is calculated from product size, spacing between units, accumulation strategy, transfer design and the rates of the machines at both ends, with average and peak rates considered separately. TRF calculates capacity for each layout from your line data instead of quoting a catalog number, and sizes buffers so a short stop downstream does not have to stop the line upstream.
Can a Conveyor System Grow When I Add Lines?
A conveyor system can grow when you add lines if it is built from modules and the layout leaves room for the next merge, divert or accumulation zone. TRFIntraflow scales from a single conveyor section to complete multi-line systems, and TRF plans for future additions with you during the layout study.
Can a Conveyor System Exchange Data With My Warehouse Management System?
A conveyor system can exchange data with your warehouse management system when the project requires it: WMS and warehouse interfaces are part of the TRFIntraflow system integration modules, together with barcode and vision interfaces and machine communication. TRF defines which data each case carries, where it is read and how the routing logic uses it during project engineering.
