Blister Handling and Cartoning Line for Pharmaceutical Tablets
A 70 cartons-per-minute cartoner fed by a 250 ppm blister flow, covering 16 pack formats with a 30-minute changeover.
Client Background
Challenges
A very wide carton size range
The sixteen formats span a large range of carton sizes. A machine that covers that range with dedicated change parts per format would be expensive to run, so the cartoner was specified to cover the range with one set of adjustable references.
Different content arrangements per format
Formats differ not only in size but in how the blisters are counted, stacked and oriented inside the carton. The infeed side therefore has to be reconfigurable rather than fixed.
Singulating blisters at 250 ppm
Blister strips are thin and easily interleaved as they leave the blister machine. Feeding and separating them reliably is a prerequisite for the cartoner holding 70 cartons per minute — a double feed stops the line, an escaped strip is a quality event.
Pharmaceutical documentation and change control
Every format recipe has to be documented and controlled. Factory acceptance testing, material certificates and a change-control trail are part of the project scope, and they have to be maintained when formats are added later.
How ZRAY Solves It
Project Results
Project Timeline
-
01
Format and blister survey
All sixteen formats catalogued for carton size and blister arrangement; reference strategy defined to avoid per-format change parts.
-
02
Design, build and documentation
Blister handling and cartoning stages built; recipe documentation and material certificates prepared alongside the machine.
-
03
Factory acceptance testing across formats
Line run at the ZRAY plant through the format range, with the customer witnessing acceptance.
-
04
Installation, commissioning and handover
Line integrated behind the blister machine; operators trained on the sixteen recipes and on the change-control procedure.
