Methods and systems for laser marking pharmaceutical capsules during manufacturing

A method of forming a capsule comprising:

• applying a laser marking to a sheet of material of a pair of sheets of material;
• and
• forming a capsule from portions of the pair of sheets of material using a pair of die rollers or another pair of die rollers;
• wherein
• each die roller of the pair of die rollers or the another pair of die rollers comprises a cavity allowing the capsule to be formed from the portions of the pair of sheets of material and a filler;
• the formation of the capsule from the portions of the pair of sheets of material using the pair of die rollers or the another pair of die rollers employs a capsule filling system;
• the capsule filling system comprises:
• a first capsule filler comprising a first set of dispensers for the first capsule filler and a first heated wedge;
• a first roller pair comprising the pair of die rollers for use with the first capsule filler;
• a second capsule filler comprising a second heated wedge;
• a second roller pair comprising the another pair of die rollers for use with the second capsule filler;
• wherein
• the capsule filling system employs the first capsule filler that can be swapped for the second capsule filler;
• the first capsule filler employs a filler in the form of at least one of a liquid, a gel and a powder;
• the second capsule filler employs another filler in the form of at least one of a liquid, a gel and a powder;
• and
• a laser marking system configured for marking the sheet of material of the pair of sheets of material prior to the formation of the capsules of different sizes.

• the capsule filling system employs the first capsule filler that can be swapped for the second capsule filler;
• applying another laser marking to another sheet of material of the pair of sheets of material;
• wherein
• the location of the laser marking on the sheet of material of the pair of sheets of material is established such that the laser marking is in a predetermined location upon the capsule relative to at least one of a seal or a joint between the pair of sheets of material formed during the formation of the capsule;
• the location of the another laser marking on the another sheet of material of the pair of sheets of material is established such that the another laser marking is in a predetermined location upon the capsule relative to at least one of a seal or a joint between the pair of sheets of material formed during the formation of the capsule;
• applying an extra laser marking to the another sheet of material of the pair of sheets of material;
• applying a further laser marking to the another sheet of material of the pair of sheets of material, wherein
• the location of the further laser marking on the another sheet of material of the pair of sheets of material is established such that the further laser marking is in a predetermined location upon the capsule relative to at least one of a seal or a joint between the pair of sheets of material formed during the formation of the capsule;
• the location of the extra laser marking on the another sheet of material of the pair of sheets of material is established such that the extra laser marking is in a predetermined location upon the capsule relative to at least one of a seal or a joint between the pair of sheets of material formed during the formation of the capsule;
• the further laser marking is on a side of the another sheet of material of the pair of sheets of material such that the further laser marking is on an inner surface of the formed capsule;
• and
• the extra laser marking is on another side of the another sheet of material of the pair of sheets of material such that the extra laser marking is on an outer surface of the formed capsule.
