KND-6040 Large Tunnel Conveyor Needle Detector for Cartons
The KND-6040 inspects sealed carton boxes rather than individual garments, which removes the step where a carton has to be opened and repacked to be checked. A wide detection area covers the whole box, sensitivity is adjustable to the product, and the conveyor keeps cartons moving through the check rather than stopping the line.

Key benefits
- Wide detection area covers the whole carton in one pass
- Cartons are checked sealed, with no opening and repacking
- Adjustable sensitivity levels for different packed products
- Conveyor integration keeps boxes moving through the check
- Detects small metallic contaminants including broken needles
Problems it solves
- Cartons have to be opened and repacked to be inspected
- Narrow detectors cannot scan the full width of a large box
- One fixed sensitivity does not suit every packed product

- Manufacturers shipping in bulk cartons
- Warehouses verifying incoming or outgoing boxed goods
Application scenarios
- Manufacturing plants checking finished cartons before distribution
- Logistics and warehousing checks on boxed goods
- Packed food items in carton format

Compared with other models in the range
A garment-level needle detector checks pieces before packing. The KND-6040 checks after packing, at carton level, which is the last point at which a stray needle can still be caught before the goods leave the building.
Use guide
- Position after carton sealing, before palletising
- Set the sensitivity for the product packed inside the carton
- Feed cartons at a consistent spacing on the conveyor
- Verify with a test needle card at commissioning and at set intervals
- Confirm aperture and belt speed against your carton size before ordering
