Embodiment Construction

[0030] figure 1 A schematic configuration of the printing plate exposure machine 1 is shown. The printing plate 3 is tensioned on the plate cylinder 2 for exposure. For this purpose, the plate cylinder 2 is drivably rotatable about an axis of rotation 14 .

[0031] A laser module 4 is provided on a movable carriage 5 for imaging the printing plate 3 . Carriage 5 is movable along feed direction 6 parallel to axis of rotation 14 of plate cylinder 2 . To this end, the car 5 cooperates with the drive screw 7 .

[0032] The drive screw 7 is rotationally driven by a stepping motor 8 . The rotational movement of the driving screw 7 is converted into the translational movement of the car 5 through the cooperation.

[0033]The threaded spindle 7 has a region 10 which is frictionally engaged with the damping disk 9 , for example by means of a felt block. Due to the frictional engagement of the damping disk 9 , it is likewise driven in rotation by the rotational movement of the thr...

Abstract

The invention relates to a driving system for a scanning or recording mechanism of a copy machine. Mechanical damping is required when the printing plate exposure machine (1) uses a stepping motor (8) as a screw driver; and mechanical damping is realized by a rotationally supported mass (9), wherein the mass is rotationally coupled with a rotating part of a driving device. Interference in the driver can be sufficiently damped through the rotating mass (9) so as to prevent resonance from being increased. The damping plate (9) has a problem of long time rolling and stopping on the end part of respective moving road section. In order to reduce dead time delta t caused by rolling and stopping, a driving system (16) is provided with a bracket device (11) at four sides of the rotationally supported mass (9).

Description

technical field [0001] The invention relates to a drive system for a vehicle, a method for operating the drive system and a printing plate exposure machine with the drive system, wherein the vehicle carries a device for imaging a stamp in an imaging device a recording mechanism, wherein the recording mechanism images the stamp along a recording line and the carriage linearly follows the stamp substantially perpendicular to the recording line by means of drive means preferably comprising a drive screw and a stepper motor movement, wherein the rotary motion of the drive is converted into a linear feed motion of the recording mechanism, wherein there is also a rotatably supported mass whose moment of inertia is significantly greater than the rest of the drive The moment of inertia of the rotating part and the mass are rotationally coupled to the remaining rotating part of the drive via a flexible coupling element, preferably a friction clutch. Background technique [0002] An ...
