How does a mail sorting machine work
A mail sorting machine, also known as an Optical Character Reader (OCR) or Intelligent Mail Processing (IMP) machine, is a high-tech device used by postal services to sort and process mail quickly and efficiently. Here's a step-by-step explanation of how it works:
Input: Mail is fed into the machine through a conveyor belt or a hopper. The machine can process a wide range of mail items, including letters, flats, and packages.
Image Capture: The machine uses a high-resolution camera to capture an image of each mail piece. The camera takes a photo of the front and back of the mail piece, which is then processed by the machine's software.
Barcode Scanning: The machine reads the barcodes on the mail piece, including the Intelligent Mail Barcode (IMb) and the Postal Service's unique barcode (PSBC). This information helps the machine identify the mail piece and its destination.
Optical Character Recognition (OCR): The machine uses OCR technology to read the address printed on the mail piece. The OCR software converts the printed text into a digital format, allowing the machine to extract the recipient's address and other relevant information.
Data Processing: The machine's software processes the extracted data, including the recipient's address, zip code, and other relevant information. The software uses this data to determine the correct sorting destination for each mail piece.
Sorting: The machine uses a combination of mechanical and pneumatic systems to sort the mail pieces into different bins or trays. The machine can sort mail by zip code, city, state, or other criteria.
Verification: Before the mail pieces are sorted, the machine verifies the accuracy of the data and the correct sorting destination. This ensures that each mail piece is delivered to the correct address.
Output: The sorted mail pieces are then collected from the bins or trays and prepared for transportation to their final destination.
Benefits: Mail sorting machines have several benefits, including:
- Increased efficiency: Machines can process mail much faster than human sorters.
- Improved accuracy: Machines are less prone to errors and can verify the accuracy of the data.
- Reduced labor costs: Machines can automate many tasks, reducing the need for human labor.
- Enhanced tracking: Machines can track the movement of mail pieces and provide real-time updates on their status.
Overall, mail sorting machines play a critical role in the efficient and accurate processing of mail, enabling postal services to deliver mail quickly and reliably to their customers.
