Kanban Replenishment Racks

Gravity flow racks purpose-configured for two-bin and multi-bin kanban pull systems — per-lane kanban card holders, color-coded signal flags, and lane depths sized to your exact kanban container quantity. Ready for electronic signal upgrade at any time.

Why Choose Kanban Replenishment Racks

Kanban replenishment racks combine the precision of gravity-flow FIFO lanes with the visual pull infrastructure that makes two-bin kanban work on the production floor.

Per-Lane Kanban Card Holders

Each lane has a dedicated T-slot clip-on card holder at the front rail. The card is visible the moment the front container is consumed — no searching, no counting, no system query needed to trigger replenishment.

Two-Bin Lane Depth

Lane depth is set to hold exactly two containers. When the front container is removed, the rear container slides to the pick face and the kanban card is visible — the line never stocks out while replenishment is in transit.

Color-Coded Visual Management

Lane tags, zone headers, and signal flag brackets come color-coded by part family or delivery route. Supervisors read the replenishment status of the entire rack from across the aisle without approaching the pick face.

Signal Flag Mounts

Red/yellow/green flag signal brackets attach to the T-slot uprights. A flag is raised when a kanban card is triggered and lowered when replenishment is confirmed — a visual closed-loop signal that requires no electricity.

Electronic Signal Ready

Lane-empty sensors, andon light towers, and wireless kanban transmitters mount on the rack frame at any time. The T-slot structure supports electronic upgrade without any structural modification or downtime.

Product Changeover in Minutes

Lane assignments change by swapping the kanban card and label insert in each holder. No structural modification, no new hardware, no rack re-ordering — the same rack supports every product mix change.

Applications

Kanban replenishment racks support pull-based material flow wherever a physical two-bin or card-based kanban system replaces MRP-driven push replenishment.

Assembly Line Kanban

Line-side two-bin kanban stations where the empty container is the replenishment signal to the warehouse supermarket.

Supermarket Kanban Lanes

Supermarket bays where each lane holds one kanban quantity and card-triggered replenishment fills the rear of the lane on the milk-run cycle.

MRO Kanban Cribs

Maintenance, repair, and operations supply cribs where two-bin kanban manages consumable and fastener replenishment without purchase order overhead.

Supplier Kanban Programs

Inbound supplier kanban programs where the empty container returned to the supplier is the replenishment order for the next delivery cycle.

Frequently Asked Questions

How does a kanban replenishment rack differ from a standard supermarket rack?

A kanban replenishment rack is configured specifically to support a two-bin or multi-bin kanban system. Lane depth is sized to hold exactly the kanban quantity, kanban card holders are installed at each lane front, and visual signal devices are mounted on the frame. The rack structure itself is identical to a standard flow rack — the kanban function is added through accessories and lane sizing.

What is a two-bin kanban system and how does the rack support it?

In a two-bin kanban system, each lane holds exactly two containers. A kanban card is attached to the rear container. When the front container is consumed and removed, the rear container slides forward to the pick position and the kanban card becomes visible, triggering replenishment of a new container into the rear loading position. The rack lane depth is set to hold exactly two containers side by side.

Can kanban card holders accommodate different card sizes?

Yes. Standard kanban card holders accommodate A5 (148x210mm) and A6 (105x148mm) cards. Custom holder widths are available for non-standard cards. Holders are available in clear polycarbonate for card visibility or colored plastic for lane color-coding. All holders are T-slot clip-on style — no drilling required.

How many kanban cards can one replenishment rack manage?

A three-tier kanban replenishment rack with a 1200mm working width manages eight to twenty-four kanban cards simultaneously, one per lane. Each card holder is labeled with the part number, kanban quantity, and replenishment destination. Modular Solutions configures the card holder layout to match the customer's existing kanban card design.

Can kanban replenishment racks be upgraded to electronic signals?

Yes. Lane-empty sensors can be added to any T-slot kanban rack without structural modification. The sensor mounts to the front lane rail and wires to an andon light tower or wireless transmitter mounted on the rack frame. Electronic upgrades can be added after initial installation as the pull system matures.
