Matrix cell

Petra Born,

The line was yesterday

Stecher Automation realizes the Smart Factory with the Matrix cell. Various manufacturing processes can be integrated. The cell links the processes in such a way that several products can be manufactured simultaneously and flexibly. An example of intelligent automation for SMEs.

Generated orders make their own, flexible way through production. Work equipment, such as the robot, sets itself up. Autonomous transport systems supply and link the production stations. This is no longer a vision - but it requires a new segmentation of production to ensure smooth interaction between robot cells, vehicle solutions and leading ERP systems. It is de facto the implementation of the Industry 4.0 concept - and the end of line production. With a modular system for robot cells, Stecher Automation enables the flexible automation of various process steps in industrial production. The modular system comprises the parameterizable control system, the modular cell structure, the modular cell equipment, the automated and flexible component feed and the system and process networking using automated guided vehicles (AGVs).

The cell equipment can be individually designed and combined for process steps such as turning, milling, cleaning, measuring or marking. The modular system also includes various test procedures and component deburring. The system is freely scalable and can cover almost any component size and type in different design variants. The robot sets itself up for the products commonly used in medium-sized companies: It can change its own tool via an automatic gripper change and change part-specific components, for example clamping devices, fully automatically. For maximum flexibility, all components are equipped with standardized interfaces for software, cable management and mechanical attachment of the cell equipment; each matrix cell can be expanded, redesigned and adapted for future changes.

The control system records both the robot's program changes and the sequence controls and component specifications of the products. It is therefore not necessary to retrofit the software. Even operators without programming experience can change the sequence program. The program is automatically adapted via an interface to the merchandise management system and quality assurance when the operating order is created; all necessary changes are transferred to the respective matrix cell via the parameter transfer. By automating the flow of goods between matrix production and the warehouse, the user can manage complex logistics. Blanks, components, tools and set-up materials are fed to the cells according to requirements and production planning. All feed modules can be loaded via an AGV. In this way, production flexibility is realized as a whole.

"Nothing is rigid or fixed anymore," confirms Simon Stecher, grandson of company founder Adolf Stecher, project engineer and member of the company administration. "The merchandise management system is directly connected to production, components find their own way through the manufacturing process, autonomous transport systems link all stations. With our matrix cells, we are putting Industry 4.0 into practice." When it comes to robotics, Stecher works with different robot manufacturers - depending on the requirements of the customer application. Stecher is also flexible in its choice of autonomous transport systems - for example, the Leo Locative from Bito, a pallet truck from Jungheinrich or shuttles from Mobile Industrial Robots. Stecher Automation has entered the Matrix cell for this year's Baden-Württemberg Innovation Award - the Dr. Rudolf Eberle Prize.
