The trend in packaging continues to be innovative approaches that simplify complex processes. One example is Bag Grippers, which are specifically designed robot grippers that handle unstable, bag-type containers and shrink-wrapped packages.

Each gripper has high suction power from its integrated ejectors. Even in the case of low suction power due to handling extremely porous goods, a side channel blower is available to generate a vacuum.

The design of the device resists contamination: The diameter of the suction channels is large enough to allow dust particles to pass through unhindered. This design eliminates downtime due to clogging of the suction channels. The seal collar adapts to the surface of the product and offers absolute gripping reliability with the lowest possible suction air requirement, while the simple exchange mechanism ensures that maintenance can be carried out quickly and cost-effectively. Compared to bag gripper units with mechanical fingers, less time is spent on adjustment and maintenance. Time-consuming lubrication of the mechanical gripper components is no longer necessary and adapting to different handling goods requirements is simple.

Since each gripping job is unique, the Bag Gripper is available in a range of custom options. Suction chambers can be split up for multi-positioning tasks or different handling requirements. In the case of a multi-positioning job, the robot-mounted gripper takes two packages from the conveyor and sets them down in different positions. At the same time, a vacuum is generated in each suction chamber individually by using valves. While one of the suction chambers is still holding the first package, the vacuum in the second suction chamber is switched off and the product is released.

To optimally adjust the gripper to specific product requirements, the depth of the vacuum chamber can be customized as well. This function allows for a secure grip while keeping air consumption at a minimum. Other functions include:

• Flexible Vacuum Generation: Integrated high-performance ejectors ensure optimal suction power. Side channel blowers are available to handle highly porous products.
• High Reliability: Contamination-resistant design reduces downtime due to dusty products.
• Low Maintenance Costs: Suction mat can be replaced quickly and easily.
• Unique Customization Options: Many different handling solutions can be created by splitting the vacuum chambers and adjusting chamber depths.
