Vetter is a leading global Contract Development and Manufacturing Organization (CDMO) with headquarters in Ravensburg, Germany, and production facilities in Germany and the USA. With many years of experience and the dedication of its approximately 5,000 employees worldwide, the company provides support from early process development through clinical and commercial filling to a wide range of packaging solutions for vials, syringes and cartridges. Vetter’s customers represent the full range from small to large companies in the pharmaceutical and biotechnology industries. With its many years of experience in the filling of sensitive active ingredients, the pharmaceutical service provider has made it its business to develop injection systems together with its clients for the continuous improvement of patient safety, comfort and compliance.
In order to make internal automation more flexible, among other things to meet the trend towards smaller batches in the pharmaceutical industry, the company was looking for an innovative, flexible and above all reproducible automation solution. The goal is to automate previously manual processes, such as the separation of transparent glass bodies (syringes) by “reaching into the box” and depositing them in trays provided for this purpose.
Three integrated robotic workstations take over the material separation, as well as the provision of empty trays and the restacking of full trays, with the aid of the latest 3D vision technology and ESSERT’s speed bin picking process.
The use of the flexible bin-picking system not only has a positive effect on process quality, but also significantly reduces human intervention and thus the risk of possible product contamination. This enables employees to perform more efficient and complex tasks.
The ARW Bin Picking Edition of the Advanced Robotic Workstation platform meets all necessary criteria for 100% compliant operation in the pharmaceutical industry. Another robotic solution in the field of syringe assembly (assembly of plunger rods and backstops) is currently being finalized together with ESSERT.
Monotonous, manual tasks, such as separating transparent glass jars and supplying empty trays and stacking full trays back, were to be automated. One of the goals was not only to entrust qualified employees with more demanding tasks, but also to positively influence process and product quality. In order to familiarize the entire workforce with this topic at an early stage, a preliminary robot cell was presented in advance at the company’s works meeting.
“One of the big challenges for us was reproducibility and cooperative/collaborative collaboration between man and machine. Performance is an equally important factor,” explains Markus Behrendt, project manager responsible for the plant and site expansion at Vetter.
“We have been familiar with classic robot cells in our everyday production since the early 1990s. The declared goal is to include innovative, open and powerful systems in our production.
To advance this goal, we considered purchasing components or working with integrators during the evaluation phase,” Behrendt continued.
“We talked to many people in the industry and to various robot manufacturers, for example at the Hannover Messe. In the process, the name ESSERT in Ubstadt-Weiher came up again and again.”
The current status
The robot platform convinces with its flexibility, reproducibility, the integration of state-of-the-art vision technologies as well as with the speed bin picking process.
“ESSERT has succeeded in developing a platform that can be used in the highest degree of flexibility and modularity, regardless of the industry,” says Arno Schroff, department manager for plant and site development at Vetter.
“The functional design with the built-in mode illumination is well thought-out and of high quality. The advantages of the platform are clear: Whether something has to be gripped, assembled or inspected, the robotic platform offers numerous fields of application. Another system has therefore already been ordered.”
With the automation solution, Vetter is able to further advance its strategic goals, make the jobs of its employees more attractive, and positively influence process and product quality.
