Task: Transport and buffering of medical items in freezer cells

Vaccines that are packaged in small blisters in a Class ISO 5 cleanroom are to be transported out of the packaging machine and through a wall into a freezer at -20°C

The wall opening should be as small as possible

In the freezer, the blisters should then be evenly distributed among 4 large containers

The containers should be filled in layers and avoiding cones to ensure that the vaccine freezes through as quickly as possible.

The parts must not be damaged during transport or fall off the conveyor line

In the cleanroom, QA removal of the parts must be possible before the parts are transported to the freezer cell

The rooms are regularly cleaned and fumigated with special cleaning agents. The materials used must be appropriately durable.

Solution: Small conveyor belts in special design with distribution switch

MTF I-Tech small conveyor belts in special design for transporting blisters

All components in stainless steel or aluminum, anodized

Special belts on the conveyor belts with a temperature resistance down to -30°C and a roughened surface to prevent parts from sticking to the belt

Conveyor belt mounted so that it can be moved along the longitudinal axis as a transfer route through the wall between the cleanroom and the freezer cell. This conveyor belt can be completely pulled out when the cleanroom is fumigated in order to seal the room airtight.

Pneumatic distribution switch at the outlet of the transfer belt through the wall to distribute the flow to two longitudinally movable conveyor belts for filling the large containers

Electric linear axis with 12 stop positions in combination with distribution switches at the outlets of the movable conveyor belts enable 24 delivery positions of the parts into the containers for optimal cooling and distribution
