Abstract
The invention describes a safety device (45), in particular a beam-emitting and beam-receiving system for a production machine (1), e.g. an edging press, with a retaining mechanism (51) for the safety device (45) on a press beam (16) to which bending and/or pressing tools can be attached. The retaining mechanism (51) has at least one retaining means (52) designed to be received in a tool holder device (35). A detection system (66) wired to the machine control system of the production machine (1) is provided between the tool holding device (35) and the retaining means (52).
Claims14
A safety device for a press device having a press beam supporting a tool holder that is structured and arranged to releasably hold bending or pressing tools, the press device further comprising a control system operable to control operation of the press device, the safety device comprising:
- a pair of cooperative beam devices comprising a beam emitter and a beam receiver operable to receive a beam emitted by the beam receiver;
- a first retaining mechanism supporting one of the beam devices;
- a second retaining mechanism supporting the other beam device;
- wherein at least one of the retaining mechanisms comprises a retaining member structured and arranged to be releasably installed in a tool-receiving slot of the tool holder of the press device so as to secure the retaining mechanism to the tool holder;
- and
- a detection system operable to detect, and to provide to the control system of the press device an indication of, whether or not the retaining member is installed in the tool holder, whereby the control system is able to restrict operation of the press device in the event that the detection system indicates the retaining member is not installed in the tool holder.
