Abstract
Abstract A sensing device for sensing individual articles such as newspapers, magazines and the like in a stream of such articles flowing along a predetermined work path. The device and method utilize a rotatably mounted polygonal sensing member having an outer peripheral surface comprised of a plurality of distinct alternating sides and corners. The sensing member is disposed at a sensing station and mounted so that the leading edge of each consecutive article in the stream engages consecutive corner and side areas of the sensing member thereby causing incremental rotation thereof. An activating vane is disposed in operative engagement with the sensing member so that during such incremental rotation, the vane is moved between non-activating and activating positions. A transducer is disposed in operative association with the activating vane such that movement of the vane between the activating and non-activating position brings the vane toward and away from a close spaced relationship therewith to cause cyclical energization and de-energization thereof. The pulses obtained from the transducer may then be employed to operate attendant equipment including, for example, a counter for maintaining an accurate count of the articles passing along the work path.
