Identification using bar code/2D code Blister control Presence monitoring Tube orientation Identification using color rings Inspection of print quality Presence and color inspection Print inspection of plain text Fill level control

Identification using bar code/2D code 1D and 2D codes are utilized in virtually all industrial sectors to identify products and to record data. The coding enables each individual product to be identified. In order to do this, the codes need to be read and inspected: 1D / 2D code A reference code is programmed in and read. All codes being inspected are compared with this reference. If the code is not exact, the system reports an error message, such as: ■ No read (code not readable) ■ Mismatch (error in code contents) The position and orientation can also be evaluated. Pharmacode reading To identify...

Presence of ampules in the tray Print control on the base of the bottle For example, when illuminated from behind, the silhouettes of the ampules appear. A green frame shows presence, a red frame indicates absence. The checks are carried out as pattern matching against a learned reference. The print control is carried out using a rotation tracker. The view from above into the carton shows whether the bottle (center), the information leaflet (above center) and the pipette (below right) are present.

Identification using color rings Color rings provide clear identification of glass ampules. In this example, ampules and vials are inspected in the same tray. Inspection criteria of ampules: ■ Number of color rings ■ Color of ring ■ Order of rings ■ Width of rings ■ Ring intervals ■ Interruptions ■ Length of total color ring code Tubes must be oriented in the filling line before closure so that the seam can always be placed precisely. This allows the orientation to take place based on the print marks or the pharmacode. The examples show a black tube with a white print mark and a tube which is...

Inspection of print quality Presence and color inspection Color evaluation can check whether, for example, a dosing spoon is present but also whether the correct color has been enclosed. This application is also suitable for caps, information leaflets and canulas. Inspecting the print quality is an essential part of quality assurance for product packaging, regardless of whether it is for design elements or printed codes. Based on given standards (e.g., ISO/IEC 15415 (2D code) or ISO/IEC 15416 (1D code), evaluations are made of criteria such as: ■ Contrast ■ Defects ■ Readability (codes) ■ Modularity...

Print inspection of plain text In addition to codes, packaging also includes numerous additional information in plain text, such as product or company information or logos, pictograms, and other symbols. Print inspection of this information is carried out using OCR/OCV reading. Inkjet printing on a PET bottle n Base of a plastic cosmetic container. b The print inspection is carried out using a rotation tracker. The print can therefore be inspected in any desired position, and even upside down. n OCV = A string reader checks the presence and c reference of the plain text characters according to...

Position Controlling the right position of packaging components and labels is an important part of quality control. Numerous criteria can be inspected such as: 3 Correct positioning of the sealing ring This checks whether the seal is in place and the lid has been put on straight. On the right-hand edge of the sealing ring, there is a tracker field which provides a reference for finding the control field. ¥1 Quality control for nasal spray Checks the position of the tip and the presence of the canula in the bottle. ^ Label on the adhesion tape roll: In this example, checks are made of the presence...

ft i t i 5_ Blister control Increasing quality and safety requirements mean it is necessary to check for further criteria in addition to simply the presence inspection. Irregularities can occur when filling pharmaceuticals in blisters, which can have relevant impacts on the quality: 3 Presence Lack of contents are unacceptable from a quality point of view and are immediately identified. b Orientation This, for example, checks for products for which the orientation are a quality characteristic (e.g., bicolored capsules). 3 Damage/position error Damaged products are ejected after clear identification....

10 Fill level control Controlling the correct fill level is an import quality criterion. In the pharmaceutical and food industries in particular, the fill level control provides reliable packaging processes. In the example, the distance between the upper edge of the lid and the fill level is measured in order to check the fill level. Background illumination is used to find the edges.
