Highly efficient & fully automatic: how to achieve perfect material ejection

Challenge: Contamination-free cleanroom production

In cleanroom production, every detail counts. Incorrect ejection can cause contamination and jeopardize the entire process. This was precisely the challenge faced by our pharmaceutical packaging customer:

How can produced packaging parts be removed fully automatically from the cleanroom be discharged fully automatically without jeopardizing cleanliness?

Conventional material pass-trhoughs often require manual handling, which is time-consuming and increases the risk of contamination. The customer needed a solution that:

• Fully automatic operation – without manual intervention
• Highest purity standards fulfilled – without particle entry
• Efficiency and safety combined – for trouble-free processes

Solution: Customized conveyor belt system with clean air filtration

Our engineers developed a special solution that meets all the requirements:

• Three separate conveyor belts with automatic control of lifting doors as airlock function
• Enclosed conveyor belt that automatically passes through the material pass-trhough
• Seamless integration into the cleanroom process

This is how the system works:

1. Production: The packaging parts are shrink-wrapped in bags directly after production and transferred to the conveyor belt.
2. Enclosure: The entire conveyor section is closed to prevent particle emissions.
3. Protection through passive air flow: Two automatically controlled lifting doors enable airlock control per bag and prevent air short circuits. The chambers are passively purged by the clean room pressure.
4. Automated ejection: An intelligent control system guarantees that the gates remain alternately closed so that no particles enter from outside.

Advantages of automated ejection

• Increased efficiency: Fully automated process reduces manual intervention and speeds up production.
• Ensuring the cleanroom class: Controlled air flow prevents contamination and keeps the cleanroom pressure constant.
• Flexibility: The system adapts to different packaging sizes and quantities.
• Safety: Manually selectable modes allow regular cleaning of the conveyor belts. Light barriers detect bags and airlock them reliably.

Why our system is ideal for cleanrooms

Our cleanroom conveyor belt system for automatic ejection combines maximum process reliability with efficiency. It protects sensitive production environments from particle emissions, reduces manual effort and increases production quality.
