Missing Item Inspection Sensors
Fast production lines need reliable systems to confirm that cartons, pallets and crates contain the right number of items. They must also ensure that primary packaging (like a bottle or jar) is correctly filled to meet consumer satisfaction and regulatory requirements.
KEYENCE provides a wide variety of measurement sensors for 1D, 2D, and 3D inspection and measurement efforts. Many of these sensors are perfect for highly accurate missing item inspections.
What is Missing Item Inspection?
During final assembly, crates, cartons, and other types of secondary packaging materials are inspected to ensure that they are completely or correctly filled. If the number or quantity of product is wrong, then missing item inspection sensors will alert the inspection point or software. Depending on the inspection system, the bad parts could then be separated for additional inspection or processing.
Key Features of Missing Item Inspection Sensors
Missing item inspection sensors must meet certain requirements to successfully identify missing bottles, bottle caps, and other secondary packaging items.
High Accuracy
A missing item sensor should not be limited to simply inspecting large objects. In many use cases, small objects must be found in large image areas. Therefore, an inspection solution must provide precise detection capabilities even in complex packaging scenarios.
Non-Contact Measurement
Inspection must occur without physical contact with the packaging material or with the content within. This is to prevent contamination, physical damage, or packaging process disruption.
High-Speed Measurement
Production lines typically move at high speeds. A food product inspection system must be able to inspect a lot of items in a short time. In some industries, this could mean 1,000 packages per minute or more. Consistency in the delivery of speedy inspection performance in a demanding production environment is another feature an inspection sensor system must have.
Advanced Algorithms
Advanced sensor and algorithm systems help analyze packaging content and accurately detect missing items while minimizing false negatives and false positives. Some systems are designed to check for completeness by inspecting the presence of bottle caps. This lets the system not only check for completeness but also if a cap is properly attached to a bottle. This type of design requires advanced sensor algorithms.
Benefits of Using Missing Item Inspection Solutions
Inspection and measurement sensors for the food and beverage industry provide numerous benefits to manufacturing and production lines—key among them are revenue and customer satisfaction. Retailers and consumers who do not receive the right quantity of products may simply opt for returns and demand refunds.
Costly chargebacks can hurt a company’s bottom line and may also damage its brand reputation. Using a missing item inspection sensor system lets companies ensure accuracy in fill levels and completeness of packaged product quantities.
Automated inspection systems greatly reduce the limitations of manual inspection. Machine sensor measurement and inspection solutions provide far fewer errors than humans. They can also inspect items at high speeds, making them perfect for high-volume production and manufacturing lines.
