Dimensioning, weighing and scanning (DWS)
Parcels never stop: dimensions, weight and barcode captured in one pass, straight into your system.
Parcels never stop: dimensions, weight and barcode captured in one pass, straight into your system.
A DWS system sits on a conveyor and measures volume, weighs dynamically and reads barcodes as parcels pass, sending the data to the WMS or carrier system in real time for freight calculation, load planning and sorting decisions. Scanning can be configured from top only up to six sides. Rejecting exceptions needs an additional reject divert. The weighing module can be certified to local metrology rules.
Typical uses
- Inbound and outbound billing in parcel hubs
- Outbound verification in e-commerce
- Volume-based billing for 3PLs
- Data capture ahead of a sorter
Key figures
| Throughput | 3,000–6,000 items/h |
|---|---|
| Belt speed | ≤ 2.5 m/s |
| Size range | 50×50×20 mm to 1,200×800×800 mm |
| Dimension accuracy | ±5 mm (certified versions per regulation) |
| Weighing | Standard ≤ 30 kg; dynamic accuracy about ±10–20 g at lower speeds, about ±20–50 g near 2.5 m/s. 100 kg heavy-duty uses a different scale, with accuracy redefined for speed and capacity |
| Scanning | Top only to six sides, 1D / 2D, read rate ≥ 99.5% |
| Interface | TCP/IP, API, links to WMS / carrier systems |
Figures are typical configuration ranges; exact specifications are set per project.
Options
- Photo record and OCR address reading
- Metrology certification (OIML)
- Print-and-apply labelling
- Reject lane for exceptions
- Liquid-lens readers with a large depth of field: no refocusing for cartons of different heights
- Label inspection: misprinted characters, incomplete logos and similar defects classified automatically, with rejects diverted
Scope of supply
- Machine, drives and control cabinet, assembled and dry-run tested before shipping
- The equipment's own control and fleet software; interfaces to your existing WMS / ERP as the project requires
- Drawings: general arrangement, foundation and anchor plan, electrical schematics
- Conformity documents for the equipment and the whole line, the split of responsibilities and the acceptance criteria are set out in the contract according to the project scope
- Spare-parts list and wear-part recommendation; a first batch can ship with the equipment
- Factory acceptance (FAT): attend in person or follow by live video
- Installation, commissioning and operator training can be included in the offer
What we need for an offer
- Parcel sizes, weights and peak-hour volume; whether parcels are already singulated, and the minimum gap
- Width and speed of the existing line
- Whether metrology certification is needed
- Systems to connect
