Securing Germany as a production location through automation - this could be the headline of the innovative, fully autonomous production line of Schuster Maschinenbau.
It is a promising joint project of 3 innovative partners from the southern German automation sector. The company Schuster Maschinenbau from Denklingen in Bavaria, the robot cell specialist HandlingTech from Steinenbronn in Swabia and the vision and control experts from Optonic in Freiburg in Baden have joined forces for a customer project to realize a fully automated line for the production of adapter shafts.
With our bin picking solution Mikado, we are the first in the process and responsible for supplying the line with parts. Challenge: chaotically lying, shiny parts - 2 bays above which the camera moves on a linear axis - empty the box! Together with our integration partner HandlingTech, who realized the loading cell, a process-safe solution for continuous operation had to be developed here.
Details of Bin Picking Application
There are many details to work out on the way to continuous operation. For example, after the camera has moved over the bays, an automatic recalibration was installed so that any inaccuracies of the linear axis do not affect the hand-eye calibration between the camera and the robot.
Post-grip check: Since saw sections can be hidden at the ends, the Ensenso camera is used to check the grip position once again after the grip. This means that we can check the grip point once again without any major impact on the cycle time and adjust the deposit position if necessary.
OPC-UA on board: while communication with the Kuka robot runs via our standard Mikado interface, we have worked with HandlingTech to develop a new standard OPC interface for communication with the system.
Empty crate: The goal was to empty the shepherd crates with several hundred cylinders as completely as possible every time. Thanks to the simple and fast handle setup in Mikado, up to 1,000 handle positions were defined per part. In addition, thanks to the completely collision-tested path planning in Mikado, even the last part can be safely retrieved from the corners.
All in all, it was a very demanding project that we were able to successfully put into operation thanks to the good cooperation with our partners. The result is a bin picking cell concept that is already planned for the next automation projects. Many thanks to the company Schuster and HandlingTech and we are looking forward to the next joint projects.
