Forming or separating device, and method for operating same

An arrangement comprising an evaluation unit (24) and at least one image-capturing sensor (20) for capturing at least one image (B), the arrangement to be used in a forming and/or separating device (10),

• wherein the forming and/or separating device (10) is configured to operate cyclically and comprises:
• a first tool part (14) and a second tool part (15),
• a drive (17) that is configured to move the two tool parts (14, 15) relative to one another in order to process an initial workpiece (12) arranged in a working area (19) between the two tool parts (14, 15), in order to obtain a processed workpiece (13),
• wherein the evaluation unit (24) is configured to be communicatively connected with the at least one image-capturing sensor (20), wherein the evaluation unit (24) is configured to determine during operation of the forming and/or separating device (10) whether a defined operating condition of the forming and/or separating device (10) has been reached and to compare the at least one image (B) captured in the defined operating condition by the at least one image-capturing sensor (20) with an assigned stored reference image (R) and/or reference model and to check based on the comparison whether a disturbance exists, wherein in case of an existing disturbance the evaluation unit (24) is configured to create an indication to a control unit (18) of the forming and/or separating device (10) in order to stop the forming and/or separating device (10),
• wherein the evaluation unit (24) is configured to evaluate the at least one image (B) as well as to create of an indication to the control unit (18) of the forming and/or separating device (10) and/or a user, whether a disturbance exists, within a predefined maximum duration, and
• wherein the maximum duration is the duration that is the most available in order to stop the forming and/or separating device (10) before endangering a person and/or a damage of the forming and/or separating device and/or a tool of the forming and/or separating device and/or a workpiece and/or a transfer device occurs.
