Definitions
- the invention relates to a safety device for a Printing machine according to the preamble of claim 1.
- the lamps are mostly around light bulbs or LEDs.
- the light indicators are the controls directly or within control panels with Controls arranged. This will display permitted / possible operating states or which function an operating element (button) based on the current machine status assigned. So it is possible with one Control element to trigger several machine running functions.
- One or more lamps in the form of incandescent lamps or LED's comprehensive display device is a display control upstream.
- the display control stands with the Machine control in signal connection, so the corresponding Machine status visualized by the light indicator can be.
- the through the controls and the machine control triggerable functions of the machine are connected by a signal connection of the controls the machine control.
- the illuminants used in current printing machines have a long service life and are insensitive to vibrations on. This is one over a long period of time available ad guaranteed.
- the sudden failure of a lamp of a display device causes that a certain machine condition or one that is present
- the corresponding operating option does not correspond to the machine status can be visualized more. So it cannot be ruled out that since an operator fails the corresponding Illuminant does not recognize an intended operation several times, which leads to malfunctions in the machine operation or can even lead to personal injury.
- DE 43 27 848 C2 describes a control device for a Printing machine known in which the control of the main drive the printing press is done redundantly. From the controls and signalers of the machine is both by the control as well as redundant to it by a monitoring device from the respective operating state highest possible engine running speed determined. The actual speed the main drive is on the part of the monitoring device with the most educated possible Compare speed and if possible exceed it permitted speed, the main drive is switched off.
- EP 0 685 338 A1 describes a safety device for a printing press is known in which the operating state is monitored by sound generators (acoustic signal generators). This ensures that the printing machine starts up only takes place if an acoustic signal has been received beforehand Warning signal has been given.
- Sound generators acoustic signal generators assigned monitoring circuit stands directly with the Main drive of the printing press in signal connection, so that if the warning signal is not given, the machine starts up is interruptible.
- the object of the present invention is therefore a monitoring device for a printing press according to the preamble of claim 1 in such a way that the Availability of visual display devices at all times can be determined.
- the at least one Illuminant display device a monitoring circuit is assigned by which the operating state the display device or the illuminant of the display device can be determined.
- the monitoring circuit stands with the display control of the display device in Signal connection so that an immediate comparison of the Display control signals as well as signals according to the operating status the signals of the monitoring circuit formed by the illuminant is feasible. Is done by the display control controlling a light source in a display device, so a corresponding signal from the monitoring circuit fed to the display device.
- the monitoring circuit can determine whether the illuminant also the respective state in the intended Way (steady or flashing).
- the elements be monitored over the entire service life. Failure
- a lamp can be placed on the control station of the printing press displayable error messages as well as acoustic Warning signals signaled immediately after detection of a failure become.
- One, for example, located on a printing unit The operator receives an acoustic warning signal directly knowledge that the one assigned to a control element Lamp has failed. So it is avoidable that the operator in faith, the appropriate command entry not have correctly executed the corresponding entries repeated and possibly triggering unwanted actions.
- the monitoring of the illuminants by the monitoring circuit is in a simple embodiment of the invention possible because the voltage drop that can be determined on the illuminant is recorded.
- the lamp is formed as a light bulb is one during proper lighting certain voltage can be tapped. With a blown Light bulb as a bulb, this is not the case, so an undetectable voltage drop is a clear indication for the failure of the corresponding lamp.
- an undetectable voltage drop is a clear indication for the failure of the corresponding lamp.
- At Formation of the lamps as LEDs result in analog Possibilities for the detection of the correct operating condition.
- a controller 2 is assigned to a printing press 1. By the controller 2 are the controls not shown triggered run commands and other functions activated.
- the controller 2 has several display devices 3 in signal connection, with a display device in the figure 3 is shown.
- the display devices 3 are the individual printing units, the feeder, delivery and assigned to other components.
- the display device 3 comprises one or more illuminants 4, which is designed, for example, as an incandescent lamp or LED are.
- the illuminant 4 is a display control 5 assigned, which in turn with the controller 2 of the printing press 1 is in signal connection.
- controller 2 sends one corresponding signal to the display control 5.
- the display controller 5 is a monitoring circuit 6 assigned, which with the display control 5 in signal or
- the monitoring circuit taps the Illuminant 4 falling voltage. So within the Monitoring circuit 6 a signal can be generated if that Illuminant 4 works properly or if despite activation on the part of the display controller 5, the lamp 4 does not light up.
- the monitoring circuit 6 with the display control 5 in There is a signal connection the failure of a lamp 4 detectable, so that on the part of the monitoring circuit 6 corresponding error signal to the controller 2 of the printing press 1 can be forwarded.
- a corresponding error message can at a control station, not shown, of the printing press 1 are displayed. Is the illuminant 4 a safety-relevant one Function assigned to the printing press 1, can the controller 2 also stops the printing press 1 (Switching off the main drive) or releasing only restricted Machine functions are effected.
