Abstract
The present disclosure relates to a method for vibration feeding of bulk material and a vibration feeder device provided for such purposes, comprising a material feed, a charging hopper including a hopper discharge, a feeder tray, a height adjustment means for adjusting a level height between the hopper discharge and the feeder tray, and a vibration driver for driving the feeder tray at an oscillation amplitude and an oscillation frequency, where a target material throughput and material specific parameters of the bulk material are input, initial parameters for the level height, oscillation amplitude and oscillation frequency are determined from these inputs, and subsequently the level height is adjusted by controlling the height adjustment means.

A method for vibration feeding of bulk material, the method comprising the steps:
- providing a vibration feeder device including a material feed, a charging hopper with a hopper discharge, a feeder tray, a height adjustment means for adjusting a level height between the hopper discharge and the feeder tray, and a vibration driver for driving the feeder tray at an oscillation amplitude and an oscillation frequency (step ST1),
- receiving or inputting a target material throughput and material specific parameters of the bulk material (step ST2),
- determining initial parameters as operating parameters, the operating parameters including a level height, oscillation amplitude and oscillation frequency (step ST3),
- setting the level height by controlling the height adjustment means (step ST4),
- operating the vibration feeder device (step ST5) by filling the charging hopper in filling phases and controlling the vibration driver at the oscillation amplitude and oscillation frequency, discharging the bulk material at the material discharge of the feeder tray,
- weight measuring a total mass as a function of time and determining a current material throughput (step ST6),
- evaluating the determined material throughput by comparing it to the target material throughput (step ST7), and
- depending on the evaluation, changing the operating parameters (step ST8) and resetting to a point before the step of setting the level height.
A vibration feeder device for vibration feeding of bulk material, the vibration feeder device comprising
- a charging hopper for receiving bulk material including a bottom hopper discharge,
- a feeder tray arranged below the charging hopper and comprising a material discharge for putting out the bulk material,
- the hopper discharge being arranged at a level height above the feeder tray,
- a vibration driver for riving the feeder tray at an oscillation frequency and an oscillation amplitude,
- a height adjustment device for adjusting the level height,
- a scales for measuring a total mass,
- a controller means which is adapted to receive a target material throughput and material specific parameters, putting out control signals to the vibration driver for adjusting an oscillation amplitude and oscillation frequency, putting out control signals to the height adjustment device for adjusting the level height, receiving a measured mass value from the scales, determining a material throughput from the measured mass values depending on time, evaluating the material throughput by comparing it to a target material throughput, and subsequently putting our control signals to the vibration driver and/or the height adjustment device depending on the evaluation.
