Bosch Rexroth simplifies BFR’s new bottle unscrambler

Its brand new robotic unscrambling unit for bottles allows to pick up tipped bottles in bulk and then deposits them on a conveyor one by one in order to feed a filling machine. The focus of development for food, cosmetics, hygiene and household products are optimized standard solutions that can be easily adapted to individual customer requirements.

Traditionally, unscrambling units rely on mechanical solutions for picking up, guiding and positioning plastic vials and bottles. Here a delta robot retrieves the packages in the loading area one by one and moves them to the conveyor belt.

"We have chosen to create a robotic unscrambling unit because this agile solution provides two advantages in comparison with 100% mechanical solutions: versatility and ease of use. This machine is designed to adapt to different types and shapes of bottles or vials, without the need for format parts," explains Thierry Fouré, Business Development Leader at BFR Systems.

Control system simplifies integration
"BFR Systems has chosen to integrate the automation and the Bosch Rexroth motion control on delta robot mechanics which were supplied blank. Here, we provided the motors, the servo drives and the control system for the complete implementation of the application," summarizes Nathanael Briand, application engineer at Bosch Rexroth in France. This architecture not only allows shorter development times, but also works in combination with any robot kinematics.

"Managing the automation and the robotic functions in one unique control system simplifies the architecture of the machine. In this way, we save development and commissioning time," explains Olivier Lecorre, Head of Automation Services at BFR Systems.

"The Bosch Rexroth control system is what allowed us to obtain the best trajectories. It’s a key element of this machine: we need optimized and fluid movements, and they need to be as smooth as possible. This is what will prevent bottle or vial losses," he adds.

BFR Systems uses controls from the ctrlX AUTOMATION portfolio for this purpose, which enable operation based on a real-time Linux kernel using apps and the provision of secure IoT functions. Programming can be carried out in various languages, from conventional PLC programming languages to high-level languages such as Python, C++ or C#.

"Using our platform ctrlX AUTOMATION, the machine manufacturers can easily record the user’s production data, perform diagnostics and remote maintenance, or even connect the machines to a MES tool," explains Nathanael Briand.

"It’s important for us to be able to connect our machines, create custom control panels, and offer remote maintenance without additional materials. ctrlX AUTOMATION works in the sense that we want to develop: complete, modular and dynamic lines which are adapted to suit the needs of our clients. This is also exactly why we chose Bosch Rexroth," concludes Olivier Lecorre.
