Control of an object conveyor system, and the removal of the object being transferred by the conveyor, requires only one signal to be daisy chained between the multiple conveyor stations shown in Fig. 1. This signal tells each station if any downstream station has an empty object buffer. This description assumes that the objects being transferred by conveyor 10 can be serviced by any one of the stations (N-1, N, N+1, N+2) which are distributed along the conveyor. It is also assumed that each station has an object buffer to hold a number of the objects being conveyed. This buffer capacity may be as small as one. As an object approaches a conveyor-to-station transfer point (11, 12, 13, 14), that station must "decide" if it will accept the object, or allow the object to pass on to a succeeding station.
