Conveyor system

A conveyor system, comprising:

• a motorized conveyor roller;
• and
• a switching device, wherein
• the motorized conveyor roller includes:
• a communication part:
• a roller tube:
• a pair of support shafts located opposite to each other for rotatably supporting the roller tube;
• a motor located in the roller tube for generating a drive force to rotate the roller tube;
• a control part located in the roller tube for controlling the motor in accordance with a control content carried by a control signal received by the communication part;
• and
• a first processing part located in the roller tube for outputting the control content carried by the control signal received by the communication part to the switching device,
• the switching device includes:
• a storage part;
• and
• a second processing part that stores the control content in the storage part when receiving an input of the control content from the motorized conveyor roller,
• the first processing part further determines whether a communication irregularity exists, and outputs the communication irregularity to the switching device when the communication irregularity is determined to exist, and
• the second processing part further causes the control part to control the motor in accordance with the stored control content when receiving an input of the communication irregularity from the motorized conveyor roller.
