Abstract

The invention relates to a printing press with at least one positioning drive, wherein at least one device of the printing press can be adjusted by means of the or each positioning drive for adapting the printing press to at least one changing printing parameter, in particular to a changing printing format and / or changing substrate thickness is. According to the invention, the or each positioning drive determines an actual torque required for adjusting the respective device and transmits the same to an evaluation device, wherein the evaluation device compares the actual torque with a desired torque preset for the adjustment and wherein if the actual torque in deviates impermissibly from the target torque, a maintenance message can be generated and output.

Description

The The invention relates to a printing press according to the preamble of the claim 1 and a method of operating a printing press according to the preamble of claim 3.

Out The practice known printing presses have positioning drives to z. B. in a Einrichtbetrieb the printing press facilities the same to adjust and so the printing press to changing printing parameters, such as z. B. a changing Print format and / or a changing substrate thickness, adapt. The positioning drives are used exclusively for Adjustment of the or each device of the printing press.

Of these, Based on the present invention, the problem is based a novel printing machine and a method for operating a To create a printing machine.

This Problem is solved by a printing machine according to claim 1.

Determined according to the invention the or each positioning drive for adjusting the respective device needed Actual moment and transmit the same to an evaluation device, wherein the evaluation device, the actual moment with one for the Adjustment predetermined target moment compares, and then where, if the actual moment is inadmissible Deviates from the target moment, a maintenance message for the respective to be adjusted device can be generated and output.

in the For the purposes of the present invention, it is proposed to use positioning drives a printing machine not only for the adjustment of facilities to use the printing press, but rather the adjustment needed To capture actual moment and with a for compare the adjustment preset target moment, and so on from this comparison to a proper functionality of the closing device of the printing press.

Then, if the actual moment in an inadmissible way deviates from the target torque, a maintenance message for the adjusting device generated and output. This is it possible to need repair facilities to identify a press in good time and for the same maintenance or service work, in good time before the corresponding institutions fail. This can affect the availability a printing press increased and downtimes thereof are reduced.

The inventive method for operating a printing press is defined in claim 3.

preferred Further developments of the invention will become apparent from the dependent claims and the following description. Embodiments of the invention without being limited to this to be closer to the drawing explained. Showing:

1 : A signal flow diagram to illustrate the method according to the invention for operating a printing press.

The The present invention relates to a printing machine, in particular a sheet-fed press, and a method of operating the same. Next Printing units and / or coating units, the printing of a substrate serve in the printing press, the press has at least a positioning drive.

Of the or each positioning drive is used to adjust at least one Setup of the printing press, so the press z. In the Setup operation to changing Print parameters, in particular to a changing printing format and / or to a changing one Substrate thickness, adjust.

in the The sense of the present invention is that of a positioning drive to adjust a device of the printing press required actual moment can be determined or detected and transmitted to an evaluation device. The evaluation device compares the actual torque with one for the adjustment predetermined target moment, in which case if the actual moment in an inadmissible manner deviates from the predetermined target torque, a maintenance registration is generated and output, the maintenance or service work for the initiated by means of the positioning drive to be adjusted device. In this case, the maintenance message is preferably from the evaluation device can be generated and output on a control station of the printing press.

The inventive method for operating a printing press is schematized in 1 shown. An adjustment of a device of the printing press by means of a positioning drive for adapting the device to at least one changing pressure parameter is in 1 through a step 10 visualized.

In one step 11 During the adjustment, the actual moment of a positioning drive, which is required for adjusting the device of the printing press, is detected or determined and transmitted to an evaluation device.

In one step 12 is checked whether the determined actual torque coincides with a predetermined torque for the adjustment or deviates in an inadmissible manner from the predetermined target torque.

Then, if in step 12 it is determined that the actual torque deviates in an impermissible manner from the specified target torque, is at step 13 branches and generates and issues a maintenance message for the respective device to be adjusted.

Will, however, in step 12 determined that the actual torque of the predetermined target torque does not branch off in an inadmissible manner, so goes to step 12 branches back and carried out this review until the adjustment process of each institution is completed.

With Help of the present invention may malfunction in facilities of printing presses adjusted by means of positioning drives be, early be recognized. Maintenance or service work on such can be adjusted to facilities be initiated in time, leaving a downtime the press due to an unforeseen failure of the respective device can be avoided.
