  • Gripper weight: 11 kg

APPLICATION EXAMPLE: SHOE BOXES

  • The boxes can be placed with the top side down or upright in the container.
  • The vision system is able to detect the number of boxes, the alignment, the XYZ coordinates and the cover. As a result, it can determine a grip point.
  • Various gripping strategies are possible:
  • Direct mechanical gripping with gripper jaws
  • Vacuum suction cup in the first step to pull the box between the gripper jaws and mechanical gripping in the second step
  • Moving the box within the container with the gripper jaws to reposition it
  • The vacuum suction cup can be placed on the cover to prevent the cover from opening while the robot is moving.
  • With the intelligent vision, collisions can be detected and thus prevented
  • Shoe box detection and determining the pick order

Technical data of the gripper

  • Flexible gripper system for handling boxes
  • Stroke per gripper jaw: 140 mm
  • Integrated Z-axis with vacuum suction cup for removing boxes on the edge or nearby
  • With the low interference contours of the gripper, the design makes it possible to dip into a trolley
  • The gripper can be adjusted to the specific application
