Abstract A vibrator (16) for the tray (10) of a vibratory conveyor (slip conveyor). The conveyor (16) includes bases (19) and (22) that include carriages (20) and (23), respectively, which are supported by resilient mountings (17, 18) on a stationary structure (37). Elongated resilient couplings (24) extend between carriages (20) and (23), with the tray (10) supported on the carriage (23). Operatively associated with the carriages (20) and (23) is a motor (25). In one embodiment, the motor (25) is an electromagnetic motor including an electro-magnet (26) and an armature (27). When the electro-magnet (26) is cyclically energised, the bases (19) and (22) are caused to move, relative to each other and relative to the stationary structure (37), so that the centres of gravity (28) and (29) are moved longitudinally along the predetermined path (30) that is substantially linear. |
