Patent ID: 7770719

Claim:
A self-correcting conveyor facility, comprising: a conveyor belt extending along a belt axis and embodied as an elastic conveyor belt; a correction roller having a lateral surface; a support for said correction roller, said support having a roller support and a fixed support, said correction roller supported in a rotatable manner in said roller support, said roller support connected to said fixed support such that said roller support can be rotated relative to said fixed support about a support rotation axis, and said fixed support disposed such that an angle results between said belt axis and said support rotation axis, which is greater than 0 degrees and smaller than 90 degrees; a displacement of said conveyor belt perpendicular to said belt axis and relative to said correction roller causes said roller support to be rotated about said support rotation axis with said correction roller and said rotation exerting a restoring force on said conveyor belt, which displaces said conveyor belt back; said elastic conveyor belt being guided around said correction roller such that said conveyor belt rests on part of said lateral surface of said correction roller; and said rotation of said roller support about said support rotation axis with said correction roller causes stretching of said elastic conveyor belt and the stretching produces said restoring force.
