Abstract
A mechanism is set forth that prevents packages from tipping as the packages are moved along a conveyor line. The mechanism employs a at least one gate, a detecting means for detecting when a tipping package has been righted and holding means for holding the gate in a closed position until the detecting means detects a righted package. In one embodiment, the mechanism comprises an upper gate and a lower gate mounted in the path of a moving conveyor belt. The upper gate and lower gate are operatively connected by a camming mechanism which prevents the upper gate from opening under the influence of the upper portion of a package until the lower gate is engaged by the lower portion of the package.
