An accumuiator conveyor (10) is equipped with sensors (40) which respond to article movement by pivoting about a vertical axis as the result of having a pair of laterally spaced wheels (41, 42) on opposite ends of a shaft (43) with one wheel (41) driven by the propelling member (17) and the other by an article supporting roller (13a). The first wheel (41) is larger than the second wheel (42) and is attached to the shaft (43) while the second wheel (42) is connected to the shaft (43) by a one-way clutch (47). Pivotal movement of the sensor results from differentiation between the relative speeds of the wheels to shift the accumulator conveyor between accumulation and transport modes.
