Used in automated package sorting, scanning tunnels conveniently integrate multiple features to capture detailed package-related data, enabling companies to reduce costs, increase efficiency, and improve customer satisfaction.
Packages flow into the tunnel of a carrier or sorter, where different devices automatically identify, measure and mark them. Users can achieve high automation levels, reducing the need for manual handling. Scanning tunnels are practical, cost effective and increasingly popular in mail, mail order and distribution companies. Available in modular form, they are flexible and users can choose features specific to their operational requirements.
In a scan tunnel it is important to identify addresses and codes correctly. This ensures fast, accurate routing of packages and allows individual items to be tracked. This leads to fast and efficient service and allows customers to check the status of their orders at any time. Traditionally, scanning tunnels relate to laser barcode scanners to identify packages, but recently introduced camera technology proves to be very beneficial.
Camera-based identification system
Camera-based systems work up to thirty times faster than laser scanners and provide excellent read speed. High resolution, line scanning cameras take photographic images of package labels. The system interprets these images using powerful digital imaging technology, computer algorithms and optical character recognition (OCR) software.
Unlike laser scanners, camera-based systems identify labels that are dirty, damaged, or even hand-written. Cameras also identify customer-specific codes and signs behind dirty, uneven or reflective plastics. In scanning tunnels, multiple cameras can be set with LED lighting to read all six pages of a package.
Video coding is a facility that allows manual entry of non-readable labels. When used in conjunction with a camera-based recognition system, identification rates approaching 100% can be achieved. The system sends images of incomplete or unidentifiable addresses or sorting codes to video coding stations through a fast and intelligent network. Here the operators indicate the information.
Scan tuner supports two types of video encoding. Online video encoding means that the information is promptly entered. When the image arrives at the terminal of less than 300ms after it is taken, address details can be specified in time for the sorter to process the package and send it to its correct destination. Offline video coding is where the images are stored and data input later.
Automatic volume measurement
Scanning tunnels often contain volume measurement devices that use lasers to determine package dimensions. Used to automate billing, this data reduces labor costs and speeds up deliveries. Volume measurement allows the system to calculate the smallest possible cube that will attach an item, ensuring effective use of transit space when loading vehicles.
Weighing in motion
Used in scanning tunnels to weigh packages, in-motion scales provide data that helps automate billing. The process does not interrupt the flow of material or limits the flow rate. Two-scale arrangements combining two weighing surfaces allow processing of a broader set of package lengths while maintaining a high throughput.
Data Storage Units
Scanning tuner equipment with data storage devices enables quick and easy resolution of demanding customer requests. Accumulated data such as volume, weight and address information are available for immediate recall and stored images show delivery times and product terms. The information is secure, safe and can not be manipulated, which gives customers and their customers security.
Clear spot detection
Another advantage of using cameras in scanning tunnels is clear point detection. The system controls the captured image for clear areas of the package and sends the coordinates to an auto-tagging device. This ensures that new labels do not hide existing information. Clear point detection is useful in applications where users want to enter a new label for their packages before they are sent.
Interface with sorting control system
Scanning tunnels easily with a wide range of sorting control systems. This makes them versatile and suitable for integration into existing applications. Built-in Modem enables remote diagnostics for troubleshooting and software downloads if updates are required.
Over the last few years, we have seen hundreds of scanning tunnels sold to warehouses, packages and postprocessors worldwide. They reduce costs, increase efficiency, and improve service levels. scanning
