SYSTEM AND METHOD FOR MULTIPLE SWEEP PROXIMITY SENSING AND CONTROL

摘要

A bin sweep system for a bin which may comprise at least two sweeps independently rotatable about a center of the bin, an alignment detecting apparatus for monitoring a relative position of a first one of the sweeps with respect to a second one of the sweeps, and an operational control device configured to selectively discontinue and resume operation of at least one of the sweeps to move the sweeps toward a maximum separation condition.

主权项

1. A bin sweep system for a bin having a floor surface and a substantially central well, the system comprising:
a center post located at approximately a center of the bin; at least two sweeps configured to rotate generally independently about the center post, the at least two sweeps including a first sweep with a first longitudinal axis and a second sweep with a second longitudinal axis, at least the second sweep having an operational zone with respect to the first sweep, the operational zone being bounded by a first outer position of the second sweep with respect to the first sweep and a second outer position of the second sweep with respect to the first sweep; an alignment detecting apparatus configured to monitor a relative position of the second sweep with respect to the operational zone; and an operational control device in communication with the alignment detecting apparatus and being configured to discontinue movement of at least one of the sweeps when the second sweep is located outside of the operational zone.
