Polimak's Latest Advancement in Bulk Material Handling: The Robotic Bag Dump Station

28 Mar 2025  |
Handling small-volume bags of bulk solids efficiently and safely is essential in dry bulk material handling facilities. Manual handling of these bags can be labor-intensive, time-consuming, and inefficient, leading to increased operational costs and potential safety risks for workers. To overcome these common problems, Polimak has introduced a groundbreaking solution for bag dump units — the Robotic Bag Dump Station. Designed for sustainability, efficiency, and cost-effectiveness, this advanced system automates bagged material unloading, cutting manual labor, reducing operational costs and environmental impact while maintaining a more sustainable workplace. Our versatile, advanced system can be applied across industries such as food processing, chemical manufacturing, pharmaceuticals, agriculture, and plastics.

Robotic Bag Dump Working Stages

The Robotic Bag Dump Station, integrated into the industrial plant, operates through the following steps:

  1. Material Transfer: The bags filled with dry bulk material are picked up from pallets and transported to the bag dump unit with the help of an articulated robot arm.
  2. Cutting Process: The bag is torn open by the bag cutting knife in the unit to release its contents.
  3. Material Discharge: The material from the cut bag is directed into the hopper for discharge.
  4. Waste Collection: Once the bags are fully emptied, they are gathered and moved to the waste disposal system.

Key Benefits and Advantages of the Robotic Bag Dump Station

The Robotic Bag Dump Station, developed by Polimak engineers, offers a wide range of advantages, ensuring efficient and automated material handling. Some of its key benefits include:

  • Robotic Operation: Equipped with an articulated robot arm, it ensures reliable and automated bag dumping with minimal human intervention while reducing processing time.
  • Sustainability: Reduces extra energy consumption, promoting eco-friendly industrial solutions.
  • Workplace Safety: Eliminates the need for manual lifting and cutting of bulk material bags, reducing the risk of worker injuries.
  • Cost-Effectiveness: Minimizes reliance on manual labor and material loss, reduces time consumption, and improves profitability.
  • Efficiency: Designed for continuous, automated operation, ensuring uninterrupted material processing.
  • Versatility: Capable of handling different types of bulk materials, making it ideal for various industries.

Key Design Parameters of the Robotic Bag Dump Station

In designing the Robotic Bag Dump Station, several parameters are taken into consideration to ensure optimal performance and efficiency:

Robot Repeatability: The ability of a robot to return to the same position and perform the same task consistently with minimal deviation.

Arm Reach: The maximum distance the robotic arm can extend to pick up and position bags accurately within the dump station.

Payload: The maximum weight the robotic arm can handle safely, ensuring smooth and reliable operation.

Cycle Time: The total time required to complete one full bag dumping process, directly affecting operational speed and productivity.
