Abstract
In a shelf storage system (1) comprising at least two shelf units (1a-1d), wherein each shelf unit has a separate moveable shelf feeder device (5) with electric drive motors (6, 7, 8), and comprising an electric energy supply circuit (P, S1, S2, S3) which supplies the shelf units (1a-1d) with electric energy, the shelf feeder devices (5) are designed for recycling electric energy produced in their drive motors (6, 7, 8) by operating them as generators back into the electric energy supply circuit, with the electric energy supply circuit distributing electric energy recycled by the shelf feeder devices among the shelf units according to requirements (arrow ES1, arrow EP).
Claims25
A shelf storage system comprising at least two shelf units, wherein each shelf unit has a separate moveable shelf feeder device with electric drive motors, and comprising an electric energy supply circuit for supplying the shelf units with electric energy, wherein the shelf feeder devices are designed for recycling electric energy produced in their drive motors by being operated as generators back into the electric energy supply circuit and the electric energy supply circuit is designed for distributing electric energy recycled by the shelf feeder devices among the shelf units according to requirements.
A process for the energy-saving operation of shelf feeder devices in a shelf storage system which has an electric energy supply circuit for supplying the shelf feeder devices with electric energy, wherein the shelf feeder devices have electric drive motors for performing motion sequences and the drive motors are designed for recycling electric energy produced by them by being operated as generators back into the electric energy supply circuit, wherein the motion sequences are controlled such that electric energy fed back into the energy supply circuit by at least one drive motor is used for at least one of activating and accelerating other drive motors.
