Labeling machinery is used to place labels on to various types of finished products. They are commonly used to label products in various environments such as textiles, pesticides, electronics, publishing, pharmaceuticals, chemicals, pallets, bottles, vials, and food items, etc. This type of machinery can be run in extremely clean conditions as well as on an open shop floor. Labeling machines form an essential part of the packaging line.
Labeling machinery can be fully automatic or semi-automatic. Some of the processes include: tamp (press down), wipe on and blow on. Labeling machinery and labeling systems can also be made to fit on tabletops.
Automatic labeling systems are typically made up of three main components: a labeling head or label applicator, a conveyor system or some other type of product transport method, and an integrated control system which stores the set-ups in its memory. Each component in the system houses many sub components. When you have your labeling machinery and components in position your automatic labeling system is ready to use. Many labeling systems have stainless steel base frames, conveyor tracks and powder coated, cast aluminum labeling heads.
Labeling machines can use either blank or pre-printed labels. They can also print other information such as barcodes and packaged dates, use before dates, and prices, etc. Pharmaceutical products such as syringes, tablets, and vials, etc, are done with high speed rotary labeling machines. The labels being applied are usually mounted as a roll and are self-adhesive. Sensors can be used to know if the label has been placed on the item.
Labels can be applied on a variety of surfaces such as: metal, glass, ceramic, shrink wrap, wood, pallet, plastic, etc. They can be applied on one or multiple faces of the product using rotary or fixed position indexing. There are various types of labeling available depending on the type of system and machinery that is used. Some of the labeling styles are vertical wraparound, horizontal wrap around, combo, top, top/bottom and front/back. Vertical wrap is used for square, rectangular, and slightly tapered shapes. Horizontal wrap is used on round bottomed vials and unstable round products. Top labeling is usually used on round jars, soft goods, and cassettes. Top/bottom is used for flat products where top/bottom labels are needed. Front/back labeling can put the labels on one, two or three sides of a product.
