Human-robot collaboration (HRC) is considered one of the most important trends in industrial manufacturing. Today, collaborative robots are already being used in large numbers to support humans in monotonous or strenuous tasks. The special feature: Humans and robots share their workspace. Human safety is a particular challenge in this context and its assurance is regulated by guidelines and standards such as the DIN ISO/TS 15066.

Haake Technik has specialized in the protection of collaborating robots with the help of contact-sensitive sensors such as safety edges, switching buffers and step mats. These specially developed tactile sensors detect contact with a person or part of a person's body and ensure that the automatic drive of the robot is switched off immediately in case of contact.

Development of a customized safety bumper - an application example

With our standardised cross-sections and materials we are able to cover a large number of potential applications. For particularly challenging applications we develop customised safety solutions that are tailored to your individual requirements and wishes in terms of dimensions, shapes, colouring and the materials used.

Together with our customer FlexLink AB, we have developed such a special version of our HSB safety bumper for the safeguarding of a collaborative palletising robot. This custom-made safety bumper meets both the individual and application-specific requirements as well as the normative specifications. The following video illustrates how the safe interaction with the collaborative palletising robot is realized in practice.
