A horizontal motorized dynamic system for pallet-carrier racks, which allows the formation of a motorized dynamic system as a specific, stand-alone electromechanical structure based on a horizontal conveyor track with motorized pulleys or motorized conveyor rollers controlled by electronic boards for each pallet position. The system is intended for dynamic pallet level racking on selective pallet-carrier racks in order to provide, in an extremely practical, safe and economical manner, complete optimization and excellent performance in the manufacturing, assembly and operating procedures of pallet-carrier racks. This is combined with extraordinary structural performance and high level economy of materials and space, and is based on a motorized dynamic system of high strength, safety and versatility.

There is provided a roller conveyor that has a function capable of specifying a failure part or a defective part. When a signal for executing a failure detection operation is transmitted from a host controller (50) to each zone controller (10), each zone controller (10) immediately activates the corresponding motor-incorporating roller (5a). Then, after a certain time, the motor-incorporating roller (5a) is stopped. A pulse interval thereafter is detected by a pulse interval monitoring program (36) to determine whether a delay phenomenon has occurred. The delay phenomenon is a phenomenon in which the pulse signal generation interval is temporarily extended.

A motorized drum having a drum shell with a motor therein, the motor having a stationary shaft, stator windings, and a stator support structure that is affixed to the stationary shaft. A rotor rotates coaxially around the stator, and a cycloidal reducer has an output that rotates at a reduced rate. The reducer output is rotationally fixed to, and is disposed within, the drum shell. An input gear of the reducer received a hollow eccentric input shaft, and is urged into eccentric motion as the input shaft rotates. The output gear urges the drum shell into rotation at same rate of rotation as the output gear. An harmonic drive speed reducer that has an input shaft provides rotatory motion to a wave generator that is disposed against a flexible splined member. The flexible splined member engages a rigid circular spline member at two radially opposed zones. Induction and permanent magnet forms of operation are used.

Disclosed is a friction conveying system, comprising a friction driving unit, a clamping unit and a friction driving component, wherein the friction driving unit comprises a rotation driving component, a first connecting rod, a second connecting rod, at least one first rollers arranged on the first connecting rod, and at least one second rollers arranged on the second connecting rod, the clamping unit comprises a clamping driving component by which the first connecting rod and the second connecting rod are moved towards each other to cause the first rollers and the second rollers to clamp the friction driving component, the first rollers and/or the second rollers are drivable by the rotation driving component to rotate, causing the friction driving component clamped between the first rollers and the second rollers to move by means of frictional force.
