Definitions
- the invention relates to a Printing machine according to the preamble of claim 1.
- In sheetfed offset presses are a variety of Switching and operating conditions of the printing press by means of lighting displayed.
- the bulbs are usually around light bulbs or LEDs.
- the LEDs are the controls directly or within control panels with Operating elements arranged. This will cause a display of allowed / possible operating states or which function a control element (push button) based on the current machine state assigned. So it is possible with one Operating 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 illuminated display can be.
- the through the controls and the machine control triggerable functions of the machine e.g., running commands) be by signal connection of the controls with the machine control causes.
- the bulbs used in current printing machines have a long life and shock resistance on. This is one over a long period of time guaranteed display.
- the sudden failure a lighting means of a display device causes, however, that a particular machine state or one of the present Machine state corresponding operating option not can be visualized more. So then can not be ruled out that, as an operator the failure of the corresponding Illuminant does not recognize an intended operator action several times, resulting in disruption of the machine running or even lead to personal injury.
- From DE 43 27 848 C2 is a control device for a Printing press known in which the control of the main drive the printing press is redundant. From the controls and signalers of the machine is both through the controller as well as redundant thereto by a monitoring device from the respective operating state one highest possible running speed of the engine determined. The actual speed the main drive is the part of the monitoring device with the respective highest possible allowed Speed compared and when exceeding this highest possible permissible speed, the main drive is switched off.
- DE 197 42 316 A1 discloses a monitoring circuit for the display of the operating status of a protective device known. To increase the reliability recorded a Measuring device the recorded by warning lamps power.
- the object of the present invention is therefore to a printing press according to the preamble from claim 1 to extend so that the Availability of optical display devices at any time can be determined.
- the at least one Bulb comprehensive display device a monitoring circuit is assigned, by which the operating state the display device or the lighting means of the display device can be determined.
- the monitoring circuit stands with the display control of the display device in Signal connection, so that a direct comparison of the Signals of the display control and the according to the operating state the lamps formed signals of the monitoring circuit is feasible. Is done by the display control driving a luminous means in a display device, so will a corresponding signal of the monitoring circuit the display device supplied.
- tapping a voltage at the bulb or by evaluating a by the operating state of the lamp generated signal is determined by the monitoring circuit, whether the bulb also the respective state in the intended Way (steady light or flashing). Does that happen?
- Illuminant off or is the operating state to be displayed not signaled in the intended way so is by the monitoring circuit generates an error signal and over the machine control at the control station of the printing press a Error message shown. It can be provided that in case of failure of safety-relevant bulbs Starting or continuing the machine is only possible when the error message has been acknowledged and the light source the display device back to an operable state has been added.
- the monitoring circuit according to the invention for the Illuminants of display devices may be the elements be monitored over the entire lifetime. Failure a light source can both over at the control station of the printing press displayable error messages as well as on acoustic Alerts are signaled immediately after detecting a failure become.
- An example located on a printing unit Operator receives by an audible warning signal directly aware that this is assigned to a control element Bulb has failed. So is that preventable the operator in the faith, the appropriate command input not to have executed correctly, the appropriate inputs repeated and possibly unwanted actions triggers.
- the monitoring of the bulbs on the part of the monitoring circuit is in a simple embodiment of the invention thereby possible, that the voltage drop ascertainable at the light source is detected.
- the bulb as a light bulb In training of the bulb as a light bulb is during proper lighting a certain voltage tapped. In a blown Light bulb as a bulb, this is not the case, so that an unidentifiable voltage drop is a clear indication for the failure of the corresponding bulb.
- at Training the bulbs as LED's give analog Possibilities for the detection of the proper operating condition.
- the forward current in one To detect supply line of the bulb is Presence / absence or the size of the forward current during the bulb operation a direct Indications of whether the bulbs in the intended manner works or not.
- a direct Indications of whether the bulbs in the intended manner works or not.
- tolerance values of the current given so that a demarcation of the state bulbs works properly - bulbs failed possible is.
- a printing machine 1 is associated with a controller 2.
- the controller 2 are the controls not shown triggered running commands and other functions activated.
- the controller 2 is provided with a plurality of display devices 3 in signal connection, wherein in the figure, a display device 3 is shown.
- the display devices 3 are the individual printing units, the feeder, jib as well assigned to further components.
- the display device 3 comprises one or more lighting means 4, which, for example, designed as a light bulb or LED are.
- the illuminant 4 is a display controller 5 assigned, which in turn with the controller 2 of the printing press 1 is in signal connection. On via the display device 3 to be visualized state is so through corresponding energizing of the lighting means 4 by the display control 5 causes. For this purpose, the controller 2 sends a corresponding signal to the display controller 5.
- the display controller 5 is a monitoring circuit 6 associated with the display controller 5 in signal or
- the monitoring circuit 6 with the display controller 5 in Signal connection is the failure of a light source. 4 detectable, so that on the part of the monitoring circuit 6 a corresponding error signal to the controller 2 of the printing press 1 is forwarded. A corresponding error message can at a control station, not shown, of the printing press 1 will be displayed. Is the light source 4 a safety-relevant Function assigned to the printing press 1, can over the controller 2 also stops the printing press. 1 (Switching off the main drive) or releasing only limited Machine functions are effected.
