Systems and methods for implementing unique offsetting stacker registration using omni-directional wheels for set compiling in image forming devices

摘要

A system and method are provided for improving stack integrity for a set of image receiving media substrates at an output of a compiler in an image forming device by positioning a particularly configured substrate handling device downstream of the output of the compiler in a process direction. The substrate handling device is configured of a plurality of omni-directional wheeled devices that provide drive (traction) normal to a motor axis under control of one of a respective plurality of independent motors while allowing sliding in the motor axis direction. The omni-directional wheeled devices, in one embodiment, are configured with small roller wheels along the periphery of the wheel. When using three or more omni-directional wheeled devices, translational movement can be combined with rotation to deliver sheets of image receiving media exiting the compiler at a correct angle and lateral position for further processing.

1. A method for handling image receiving media substrates in an image forming system, comprising:
providing a substrate handling device as a transport mechanism for collecting and registering a set of processed image receiving media substrates exiting an output of an image receiving media substrate processing device, the substrate handling device comprising:
a plurality of omni-directional wheeled devices that collectively form a substrate collection and handling surface for processed image receiving media substrates exiting the output of the image receiving media substrate processing device, anda plurality of independent motors respectively and independently controlling a rotation each of the plurality of omni-directional wheeled devices, receiving, with the substrate handling device, a plurality of processed image receiving media substrates exiting the output of the image receiving media substrate processing device; and operating the substrate handling device to translate the plurality of processed image receiving media substrates in at least one of the process direction, a cross process direction and angular skew based on individual speeds of the plurality of independent motors.
