Abstract
A registration system for a rotary press including circumferential and sidelay registers designed to interface to the press unit using more direct motion translation. In particular, to go from rotational motion of a motor to linear motion of the adjustment with fewer transitions. Also discussed are measurement systems which measure the adjustments made to the plate cylinder more directly by measuring the linear movement of components acting on the cylinder as opposed to the movement of the motor or power source of the registration system. These systems can provide for more accurate movement to the various elements.
Claims20
A circumferential register for a plate cylinder of a rotary press comprising:
- a motor for providing rotational motion;
- a worm shaft mechanically interconnected with said motor, said worm shaft exhibiting linear translation from the rotational motion of said motor;
- a bearing, said bearing connected between said worm shaft and a drive gear of said plate cylinder such that said bearing can transfer linear, but not rotational, translation;
- a position emitter rigidly connected to said worm shaft;
- and
- a linear transducer for detecting the linear motion of said magnet.
The register of claim 6 wherein said control panel instructs said motor based on said output from said linear transducer.
A sidelay register for a plate cylinder of a rotary press comprising:
- a motor;
- a worm screw jack driven by said motor, said worm jack being mechanically connected to a hub supporting said plate cylinder by a drive shaft, said worm screw jack providing linear translation to said drive shaft;
- a position emitter attached to said drive shaft;
- and
- a linear transducer for detecting linear motion of said magnet.
A register of a rotary press comprising:
- means for providing linear translation, wherein said means operates to linearly translate at least one of one of a plate gear or a plate hub;
- and
- means for measuring said linear translation;
- wherein said means for measuring directly measures said linear translation of said means for providing linear translation.
