Which packaging conveyor type should you choose?
Choose the conveyor family from the support, control and interface duty required by the actual pack. The product trial and line sequence should decide the final route, not the equipment name alone.
Select the conveyor by what it must control.
A belt conveyor is a strong starting point when a pack needs continuous base support. Slat or tabletop chain is often used for guided bottles and jars. Modular belt can provide a broader linked support surface. Side-grip conveying supports a suitable container from the sides, while incline, curved and accumulation equipment solve specific route or buffering duties. One packaging line can use several types where each performs a distinct task.
Packaging conveyor types compared
| Conveyor family | What it controls | Useful starting point | Critical proof |
|---|---|---|---|
| Continuous belt | Full-base support and straightforward transfer. | Cartons, trays, tubs and stable packs. | Grip, tracking, transfer gap, cleaning and loaded duty. |
| Slat or tabletop chain | Guided container flow, including suitable curves. | Bottles, jars and rigid containers. | Base support, guide contact, back pressure and restart. |
| Modular belt | Linked support surface in configurable widths and routes. | Rigid or semi-rigid packs needing broad support. | Hinge/open-area effect, transfers, cleaning and product base. |
| Side-grip | Controlled side support with the base exposed or during a level change. | Suitable rigid bottles and containers. | Wall stiffness, contact area, marking and entry/exit stability. |
| Incline or cleated route | Movement between working heights. | Packs that remain controlled on the selected surface and angle. | Rollback, sliding, cleat fit and both transitions. |
| Curved route | Change of direction within the available footprint. | Stable packs that can remain guided through the radius. | Orientation, guide load, access and entry/discharge behaviour. |
| Accumulation or rotary buffer | Temporary storage and controlled recovery. | Lines that need to absorb a defined interruption. | Usable capacity, contact limit, full response and release sequence. |
Questions that turn a conveyor name into a defensible choice
Use the answers below to decide what the product trial and supplier proposal must demonstrate.
Can one packaging line use several conveyor types?
Yes. A line may use slat chain for guided bottle transport, a short side-grip section for base coding, a controlled belt zone before inspection and a rotary or inline buffer after processing. The key is to define the product state and control duty at every transition so each conveyor type solves a clear problem rather than adding an unnecessary interface.
When is a continuous belt a poor starting point?
A continuous belt may be a poor starting point when the product must negotiate a tight chain curve, expose its base, tolerate sustained accumulation without surface contact, or remain positioned by a container-specific guide geometry that the belt route cannot provide. It can still be part of the line; the decision should follow the limiting product and transfer test.
Why is a conveyor name not a complete specification?
The name does not define usable width, working height, support surface, transfer geometry, speed range, drive position, guides, controls, environment, guarding or acceptance conditions. Two “belt conveyors” can therefore suit completely different duties. A usable specification links the equipment family to the actual pack, machine interfaces and operating sequence.
What evidence should decide the final conveyor family?
Use representative product samples, a measured layout, machine interface drawings, the required good output, normal and abnormal line states, cleaning method and a witnessed product trial. The final choice should show stable transfer, controlled restart, acceptable product contact and practical access under the agreed conditions.
Reduce the options in five controlled steps.
- List every format and identify the limiting base, height, weight, stiffness, surface and closure.
- Map every transfer, change of direction, change of height and machine datum.
- State the required pitch, orientation, accumulation and stop/restart behaviour.
- Compare conveyor families against the same evidence and acceptance criteria.
- Trial the limiting products before the design is released.
