Definitions

  • the invention refers to a conveyor arrangement.
  • a typical conveyor arrangement is described in WO 2019/110841 A1, also published as US 2020/387142 A1.
  • a typical conveyor arrangement comprises a plurality of motorized rollers. The conveyor arrangement is divided into several conveyor zones. Based on the determined presence of an object to be conveyed a zone controller controls operation of one of more conveyor zones. Each motorized roller has an integrated motor controller, which controls operation of the motor within the motorized roller.
  • the motor including the motor controller is powered by a first power supply.
  • the zone controls are provided by a second power supply which is different to the first power supply in order to provide the zone controls with power even if the first power supply is shut down in an emergency stop mode.
  • US 2020/387142 A1 discloses a control device for a conveyor, comprising: a control unit adapted to generate control signals for a conveyor device; a data interface adapted for signal transmission of control signals to the control unit; a first energy interface adapted for an energy supply to the control unit; a connection interface adapted to establish a signal control connection and a power supply connection between the control unit and a conveyor unit located outside the control device; a second energy interface adapted for supplying energy to the control unit.
  • the first interface is adapted to receive a power supply in the form of a power supply with a first voltage and the second interface is adapted to receive a power supply in the form of a power supply with a second voltage or, instead of the second voltage, with a third voltage having a level that is different from a level of the second voltage.
  • the power supply can be interrupted via the power supply line, so that no drive voltage is applied to the power supply line.
  • the motor-driven conveyor rollers are immediately not supplied with drive voltage, so that they come to an immediate standstill.
  • the separate logic voltage line continues to supply voltage so that the control units are continuously provided with power and data loss is avoided.
  • US 2012/0046784 A1 discloses a conveyor system, comprising a number of conveyor motors and at least one control unit that is connected to each conveyor motor for sending data for regulating and/or controlling the conveyor motors.
