A tool changer set out having a master unit and a tool unit. The master unit comprises a safety controller with two separate processing circuitries, a coupler and at least two coupling sensors. The tool unit comprises at least one tool unit sensor, the at least one tool unit sensor provides two output signals sent to the safety controller. The at least two coupling sensors individually detect if the tool unit is coupled to the master unit and the output signals are sent to the safety controller. The two separate processing circuitries are arranged to receive a request to decouple the tool unit, determine whether the tool unit is coupled to the master unit and whether the tool unit is in the tool stand, send the result of the determinations to other processing circuitry, receive a result of determinations and send a decouple signal.

Safe tool changer

A system and a method for controlling movements of an industrial robot during a work cycle including visiting and performing work on a plurality of workstations in a work cell. The system includes a set of predefined workstations. Each workstation includes preprogrammed robot code adapted to the workstation, an entry point defining the entrance position to the workstation, and one or more predefined paths to be followed by the robot at the workstation. A user interface is adapted to provide information about the predefined workstations and allows an operator to select one or more of the predefined workstations and to specify a desired part flow between the workstations. A scheduling unit is adapted during execution of the work cycle to schedule the execution order for the workstations based on the workstations selected from the predefined workstations and the desired part flow, and to control the movements of the robot based on the scheduled execution order and the predefined paths.
