Abstract
The invention relates to a conveyor system for conveying individual piece goods, comprising: a number of conveyor motors and at least one control unit for sending data connected to each conveyor motor for regulating and/or controlling the conveyor motors. According to the invention, the control unit is connected with a bus line, a conveyor motor, and preferably each conveyor motor by means of the bus line, preferably without electrical contact. According to the invention, it is also provided that the modem(s) is/are designed in order to take energy for driving the conveyor motor and at least one data signal for control/regulation of the conveyor motor from the bus line and send them to the conveyor motor.
Claims25
Conveyor system for conveying individual piece goods, comprising:
- a number of conveyor motors;
- at least one control unit that is connected to each conveyor motor for sending data for regulating and/or controlling the conveyor motors;
- wherein at least one control unit is connected via a bus line to at least one conveyor motor, the bus line being connected without direct conductive electrical contact to at least one modem, and wherein the at least one modem is designed to take energy for driving the conveyor motors and at least one data signal for control or regulation of the conveyor motor from the bus line and supply it to the conveyor motor,
- further wherein the conveyor motors, the at least one control unit, the bus line, and the at least one modem are mounted stationary within the conveyor system,
- wherein a configurable modem that has a coupling part that is designed to read energy and signals out from the bus line and to feed signals into the bus line and has a configurable connecting part that is configurable, in order to bring the energy and/or the signals for a consumer or sensor into the form required by the consumer or sensor,
- wherein the configurable modem is connected inductively to the bus line for transfer of the drive energy of the conveyor motor and the effective coupling length of the coupling is changeable to adjust the voltage of the drive energy transferred inductively from the bus line, and
- wherein the modems are inductively connected to the bus line for the transfer of the drive energy of the conveyor motor and the inductive coupling of a first modem for transfer of an electrical drive energy with a first voltage and the inductive coupling of a second modem for transfer of an electrical drive energy with a second voltage that is different from the first.
Method for the conveyance of piece goods, comprising:
- applying an electrical alternating voltage to a primary conductor in a bus line;
- modulating a data signal to the electrical alternating voltage;
- transferring by induction of the electrical alternating voltage to a first secondary winding in a first modem and conducting the current generated in the secondary winding to a first conveyor motor for driving the first conveyor motor at a first voltage;
- reading the data signal out of the primary conductor in the first modem and conducting the data signal read to the first conveyor motor for controlling and/or regulating the first conveyor motor;
- transferring by induction of the electrical alternating voltage to a second secondary winding in a second, configurable modem and conducting the current generated in the second secondary winding to a second conveyor motor for driving the second conveyor motor at a second voltage;
- reading the data signal out of the primary conductor in the second, configurable modem and conducting the data signal read to the second conveyor motor for controlling and/or regulating the second conveyor motor;
- and
- conveying the items with the conveyor motor, wherein the conveyor motors, the bus line and the first and the second, configurable modem are mounted stationary within the conveyor system,
- wherein said second, configurable modem reads energy and signals out from the bus line and to feed signals into the bus line using a coupling part that is configured to bring the energy and the signals for the second conveyor motor into the form required by the second conveyor motor,
- wherein the first and the second, configurable modem are inductively connected to the bus line for the transfer of the drive energy of the conveyor motor and an inductive effective coupling length of said first modem for transfer of an electrical drive energy is different from an inductive effective coupling length of said second, configurable modem for transfer of an electrical drive energy such that said second voltage is different from said first voltage.
