Container switching


Container switching prior to their introduction into automated warehouses requires tremendous amount of labor. Nevertheless, the difficulty of alignment as well as the difficulty of automating picking have impeded automation of the process by robots over many years.
In a world first, the Teachless technology of the MUJIN Controller was successful in automating container switching, making it possible for the robots to align the items while taking into account the continually changing conditions within the container.

Conventional methods - Problems


  • For storage in automated warehouses etc., transfer to collapsible or plastic containers is necessary, and this is all processed by humans.
  • As this is human work, mistakes by the workers lead to stock misalignments etc.
  • This was a difficult process to automate due to the very wide variety of boxes handled.

MUJIN system - Solutions


  • With MUJIN's 3D vision system, this process, so difficult to automate until the present time, is now automated even for a very wide variety of products.
  • Since products are placed tidily, without collisions, on the placement side, container switching is safe and efficient.

Feature 1 MUJIN 3D Vision handles ultra-wide ranges of products

Conventional methods - Problems


  • With no registration system just for box-type objects, vision recognition settings are required for each product type.
  • Design pattern registration is also impossible, so recognition mistakes occur.

MUJIN system - Solutions


  • Various products can be registered, from boxes to bottles.
  • With MUJIN’s proprietary registration system, anyone can easily register product types.
  • Speeds and suction areas can be customized for each registered product to achieve more stable picking.

Feature 2 Automatic picking to handle various load conditions (disordered loads)

Conventional methods - Problems


  • Picking from a disordered loading condition is extremely difficult, as it requires extensive teaching for each type of product.
  • Since neat packing cannot be performed well, space efficiency is poor.
  • Ultimately, it is necessary to produce a flat loading state, which requires extra man hours.

MUJIN system - Solutions


  • With MUJIN's Teachless technology, picking can be automatically started whatever the loading condition and product are.
  • With the advanced interference avoidance function, deep boxes can be used as well.
  • Because it is “Teachless”, a very large variety of products can be handled.

Feature 3 Sensitive autonomous placement function that won’t damage customers' products

Conventional methods - Problems


  • With a teaching-based robot, it is not possible for the robot to be controlled in real time so that it can adapt to the continually changing conditions within a box.
  • Products can only be dropped from a fixed point over the box, which can damage them.
  • Since neat packing cannot be performed well, space efficiency is poor.

MUJIN system - Solutions


  • Products can be placed in the container with no gaps.
  • Since products are placed aligned into gaps, as they would be by a human being, they are not damaged through collisions.
  • Since the container on the placement side is also constantly monitored, when loads collapse, approaches will be made only after checking the situation.

Feature 4 Intelligent hand control tailored to products - Handling many products is possible with a single hand -

Conventional methods - Problems


  • Two products may be accidentally taken because product-specific suction control cannot be performed.
  • Heavy items may be thrown clear because the speed cannot be adjusted according to the product.

MUJIN system - Solutions


  • Product-specific suction control is performed so that two products will not be taken in error.
  • The speed can be adjusted according to the product so, for example, speed is suppressed for heavier products, and a fine level of control can be performed.
