Abstract

A method for preventing disturbances during the start up or operation of a printing press includes the steps of (a) detecting current measurement values for selected parameters of the printing press automatically and continuously during at least one of production start up and operation; (b) automatically comparing the current measurement values with at least one defined limit value for each parameter for the purpose of determining whether the measurement value exceeds and/or falls below a defined limit value and/or lies outside a value range defined by limit values; (c) for each current measurement value, automatically generating an alarm message and/or an operational status message based on the determination; and (d) automatically transmitting the alarm message and/or the operational status message to service devices of the printing press operator and/or the manufacturer of the printing press and/or and the supplier of the operator or manufacturer.

Claims

1. A method for preventing disturbances during start up and operation of a printing press, said method comprising:

detecting current measurement values for selected parameters of the printing press automatically and continuously during at least one of start up and operation;

automatically comparing the current measurement values with at least one defined limit value for each said parameter;

for each said current measurement value, automatically generating at least one of an alarm message and an operational status message based on said comparing; and

automatically transmitting said at least one of an alarm message and an operational status message to at least one of service devices of the printing press operator, the manufacturer of the printing press, and the supplier of the operator or manufacturer.

2. The method of claim 1 further comprising, for each said current measure value, determining at least one of whether said measurement value exceeds a defined limit value, falls below a defined limit value, and lies outside a value range defined by limit values.

3. The method of claim 2 wherein, when it is determined that one of said measurement values exceeds a defined limit value, falls below a defined limit value, or lies outside a value range defined by limit values, thereby indicating that a disturbance during start up or operation is to be expected with a defined degree of probability, an alarm message for the corresponding parameter is generated in an event-controlled manner.

4. The method of claim 2 wherein, when it is determined that one of said measurement values does not exceed a defined limit value, fall below a defined limit value, or lie outside a value range defined by limit values, thereby indicating that a disturbance during startup or operation is unlikely, an operational status message for the corresponding parameter is generated periodically.

5. The method of claim 1 further comprising automatically storing said current measurement values and at least one of at least one said alarm message and at least one said operational status message.

6. The method of claim 3 wherein said alarm message is generated on the basis of at least one of manufacturer-specific limit values and operator-specific limit values.

7. The method of claim 1 further comprising automatically generating an alarm message after a disturbance in production start up or production operation occurs.

8. The method of claim 1 further comprising, when a disturbance in start up or operation occurs, automatically analyzing said measurement values for the purpose of diagnosing the disturbance.

9. The method of claim 1 wherein said transmitting comprises sending said at least one of an alarm message and an operational status message as e-mail over at least one of the Internet and an intranet.

10. The method of claim 1 further comprising, when an alarm message is generated, generating at least one of service instructions and maintenance instructions for correcting the corresponding disturbance.
