On the journey from manufacturer to consumer, packaging protects all types of product, including foods, pharmaceuticals, white goods and cosmetics. Although packaging helps bring competitive products to target markets in the best possible condition, costs are often significant, and automation helps minimize the impact.
Plastic containers, filled with liquid food products, are hermetically sealed at a Portuguese food-processing plant. Prior to containers being capped and packed in bulk, in-line testing confirms that each one has been correctly sealed. A long-distance inductive sensor, positioned directly over the packaging line, senses the presence of an aluminum-foil seal over the top of each container.
In a bottling plant, filled bottles are capped and then shrink-wrapped together to produce rigid packs of bottles. A missing cap or bottle is a serious quality fault that must be eliminated reliably.
An American beverage producer conducts a final, pre-shipment check on all cases of bottles after the corrugated cardboard case has been sealed. Product integrity is verified by detecting bottle caps through layers of cardboard at the top of each sealed case.
Modern packaging machines for the food industry rely on fast product changes and smooth-running processes. RFID data modules for format tool identification give the users of food packaging machines the flexibility and safety they need when they have to change format tools quickly.
A consumer packaging company supplies toothbrushes in individual blister packs to stores. Production quality checks include final verification that the intended product is present in each blister pack prior to shipment to the store shelf. A fiber-optic solution meets both the technical challenges and space constraints of this application.
A Japanese manufacturer of canned products uses inductive sensors with analog outputs in the packaging department to check that closed cartons have the required number of cans inside. The sensor’s analog output enables it to process different can sizes and materials in a final pre-shipment quality check for a range of product types.
A US manufacturer of aerosol cans needs to ensure that, for each can, only one bottom is inserted into the press that applies and crimps the bottom to the can body. This checking must be accomplished without physical contact while the product is moving.
