A secure roller controller of a roller conveyor system for logistics services includes a monitoring circuit, a controller module and a driving circuit and is electrically connected to a motor. The monitoring circuit is electrically connected to the controller module and the driving circuit to receive a power signal from the driving circuit. The controller module is electrically connected to the driving circuit to receive the power signal and instruct the driving circuit to drive the motor for speed adjustment according to the power signal. When instantly detecting that the power signal is irregular, the monitoring circuit transmits an irregularity signal to the controller module for the controller module to instantly decelerate a rotation speed of the motor to a safe rotation speed through the driving circuit. Accordingly, burn-down of the motor and the secure roller controller can be avoided to enhance operational stability and safety.

The present invention relates to a robotic device for inspection of components of a belt conveyor comprising a mobile platform and a robotic arm having a first end coupled to the mobile platform and a second end, in which the robotic arm comprises an articulated structure configured to guide the second end to contact at least one of the components of the belt conveyor and where the robotic device comprises a vibration sensor, a camera, a microphone and a laser scanner coupled to the second end of the arm. The present invention also discloses a method for inspecting components of a belt conveyor using a robotic device, comprising the step of: obtaining temperature and/or noise data of at least one of the components of the belt conveyor; and, if the temperature and/or noise data of at least one of the components are outside a predetermined range of values, the method further comprises the steps of: driving a second end a robotic arm of the robotic device for contacting at least one of the components of the belt conveyor, in which the robotic arm comprises an articulated structure; and obtaining vibration data from at least one of the components through the vibration sensor.

A skate wheel conveyor system includes a pair of frame sides of a frame assembly. A plurality of preassembled rollers is received between the pair of frame members. Each of the rollers includes a plurality of wheels interposed between a plurality of spacers and a shaft receiving the plurality of wheels and the plurality of spacers. A quick assembly system retains the rollers between the pair of frame members and minimizing deflections of the preassembled rollers.
