A conveying system includes a photoelectric sensor and a gate where the sensor senses objects having triangular cross sections that are conveyed past the sensor by the conveyor system and the gate is configured to close across the conveyor path and hold back the objects having triangular shaped cross sections.
Claims26
An apparatus for sensing conveyed objects, the apparatus comprising:
- a conveyor for conveying objects in a first direction along a conveyed path;
- and,
- a photosensor positioned adjacent the conveyor to emit a beam of light from the photosensor in a second direction across the conveyed path, the second direction being oriented at an oblique angle relative to the first direction.
A method of sensing conveyed objects having a triangular cross section, the method comprising:
- conveying the objects in a single file line in a first direction with at least some of the objects abutting each other;
- positioning a photosensor adjacent the conveyed line of objects to emit a beam of light from the photosensor in a second direction that is oriented at an oblique angle relative to the first direction.
