Reliable, cost efficient and simple to operate
The new intelligent bin picking solution: SHAPESCAN3D
Revolutionary application for bin picking offers highest production efficiency
The feature referred to as random bin picking is one of the most demanding of robotic applications. Up until now there have been very few robot installations with this function, because high demands were placed on rugged design and cycle time. With the new SHAPESCAN3D, ISRA VISION is now offering a highly flexible and cost efficient solution for " bin picking", which has now been developed even further. This application makes any complicated mechanical solutions that individually pick through components or alternatively any manual sorting solutions entirely obsolete. In addition, the "Plug & Automate" concept even allows users to quickly install and put this solution into operation without requiring expert knowledge - an advantage unmatched by anything else on the market.
Even in the most modern production operations, lattice boxes and EURO palettes are loaded unsorted. Oftentimes, this makes it easier to make full use of the available volume. Moreover, having to sort the loads onto palettes and boxes would take too much time and be too costly.
Unloading manually, mechanically or by robot
The challenge now is to consistently unload unsorted parts from transport packaging and to feed them to an assembly or processing system. In the past, one solution has been to remove parts by hand; however the disadvantage here is the need to staff these positions for a very monotonous job that has no tolerance for errors. In addition, this work must be performed in part in very difficult conditions in terms of safety. A flexible, automated application would provide the help needed here.
The automated removal of work pieces from a bin or lattice box takes the classic form of separation systems such as vibratory tumblers or spiral conveyors. However, these solutions are loud, take up a lot of space, are not flexible and extremely costly. Robot systems designed for bin picking offer a much more elegant and price effective method.
Machine vision systems make it possible to use robots in an application of this kind. Direct bin picking ensures a high level of flexibility despite the many different varieties of components that need to be taken up, because no sorting solution based on each different work piece is required. Overall costs are reduced due to the fact that fewer mechanical components are necessary. The SHAPESCAN3D sensor offered by ISRA VISION utilizes two standard cameras and special illumination options that make it possible to exactly define the position of each part in the box in 3D. Geometric primitives are determined in the dot cloud in a first step using the 3D shape sampling evaluation method. The software then compiles more complex objects based on these primitives. This way, even objects of different forms and sizes can be reliably identified at any height and their position can be accurately determined. This guarantees that the geometry of parts can be reliably detected, even if the objects are unsorted.
"Plug & Automate" for non-experts
All of the experience and expert knowledge required for bin picking is made directly available to users with the "Plug & Automate" solution. They can easily install these solutions with the SHAPESCAN3D sensor on their own and put it right into operation themselves. It is easy to start working with 3D robot guidance, because instead of complicated programming, all you will need to do is to set a few simple parameters. The days when users had to rely on experts to efficiently automate their systems are now a thing of the past.
The sensor can be mounted stationary above the bin. No complicated kinematics technology is needed for the sensor to work. Once installed, the user has a complete overview of standard-sized bins up to a size of 1200 x 1000 x 800 mm³. The working distance is 2000 mm. The highly flexible GigE based system works extremely fast: The scan time of the overall volume takes less than a second. The structured light ensures pictures are recorded at rapid speeds without requiring the sensor, robot or container to be moved. The sensor is not sensitive to ambient light. Moreover, measurements do not depend on the color of the components.
The system offers a high degree of accuracy and is even designed to remove an array of different components with a single scan, which significantly shortens the cycle time. The compact design, well-suited for industrial purposes, makes it easy to integrate and assemble the system quickly. A return on the investment is realized in record time. The sensors thus demonstrably reduce costs and increase flexibility in production.
