Description of operation:

• The packaging machine SB 51-1/T (SB 53-2/T) s a vertically operating, fully automatic forming-, filling- and sealing machine for the production of very small tubular bags, the so called “Stickpacks”.
• The machine processes flexible, composite films (foils) from the flat foil reel.
• In a sequence of single operations, the film is drawn off from the reel, formed to a tube during transportation and sealed lengthwise, filled then, sealed transversally and cut off.
• The SB 51-1/T is a 1 lane machine.
• The SB 53-2/T is a machine with 2 lanes in one housing.

High-precision dosing into Stickpacks

APPLICATION AREA:
• Pharmaceutical industry
• Chemicals industry

RANGE OF PRODUCTS:
• LIQUIDS
  e.g. vaccines, reagents, analysing liquids…
• POWDERS
  e.g. pharmaceutical powders…
• GRANULES; SMALL PIECE GOODS
  e.g. pharmaceutical products, micro tablets

DESCRIPTION OF OPERATION:

This system is mainly developed to control the net weight of a Stickpack by leaving out the influence of the weight of the wrapping material.
To this end, empty bags are put into carriers - manually or supplied by a MERZ packaging machine.
The filling and weighing of the bags is performed in several steps. The filled Stickpack carriers are being conveyed step by step via a transport system.

1. Step: The empty bag is weighed together with the carrier (tara)
2. Step: Dosing or rather filling of product 1
3. Step: Weighing of product 1
4. Step: Horizontal sealing product 1 (Option for separation of product 1 and product 2)
5. Step: Dosing or rather filling of product 2
6. Step: Weighing of product 2
7. Step: Horizontal sealing (closing of Stickpack)
8. Step: Waiting position (reserve position e.g. for control by camera)
9. Step: Sachet sorting into good and bad bags with reject verification
10. Step The empty carrier moves on, back to the starting position
