Abstract

A method for tipping out a cargo load from a reception unit includes providing the reception unit on a lifting device of a work machine, performing a tipping out process of a mass of cargo load from the reception unit, detecting a predetermined residual mass of the cargo load remaining in the reception unit, detecting a predetermined loading mass tipped out during the tipping step, and completing the tipping out process as a function of the predetermined residual mass or the predetermined loading mass.

First claim

The invention claimed is:

1. A method for tipping a cargo load from a reception unit, comprising:
determining via a weighing device connected to a sensor system and a control unit an initial mass of the cargo load in the reception unit;
registering via the control unit a total target quantity representing a total cargo load to be tipped out at a loading station;
registering via the control unit a current total quantity representing the cargo load already tipped out at the loading station;
determining via the control unit to partially tip out the cargo load if the initial mass is greater than a first difference between the total target quantity and the current total quantity;
determining via the control unit a residual mass of the cargo load to remain in the reception unit based on a second difference between the initial mass and the first difference;
determining via the control unit a setpoint value of a tipping angle of the reception unit corresponding to the residual mass based on stored calibration data including specific nature, particle geometries, temperature, and moisture content of the cargo load and a holding time of the tipping angle;
tipping via the control unit the reception unit to the setpoint value of the tipping angle for a defined holding time so that the residual mass remains in the reception unit;
determining via the weighing device a current mass of the cargo load in the reception unit;
shaking via the control unit the reception unit for a defined shaking duration when the current mass is greater than a sum of the residual mass and a tolerance mass;
modifying via the control unit at least one of the defined shaking duration and the tipping angle based on a third difference between the shaking mass and a defined mass limit value when the shaking mass is less than the defined mass limit value; and
determining via the control unit whether the current mass is less than or equal to the sum of the residual mass and the tolerance mass when the tipping angle is less than a defined maximum tipping angle, which is less than a mechanical end-stop of the reception unit.

2. The method of claim 1 , wherein the control unit modifies the defined shaking duration and increases the tipping angle based on the third difference between the shaking mass and the defined mass limit value when the shaking mass is less than the defined mass limit value.

3. The method of claim 1 , further comprising:
reducing the tipping angle to a defined initial angle when tipping angle is greater than or equal to the defined maximum tipping angle.

4. The method of claim 1 , further comprising:
reducing the tipping angle to a defined initial angle when the current mass is less than or equal to the sum of the residual mass and the tolerance mass.

5. A method for tipping a cargo load from a reception unit, comprising:
determining via a weighing device connected to a sensor system and a control unit an initial mass of the cargo load in the reception unit;
registering via the control unit a total target quantity representing a total cargo load to be tipped out at a loading station;
registering via the control unit a current total quantity representing the cargo load already tipped out at the loading station;
determining via the control unit to partially tip out the cargo load if the initial mass is greater than a first difference between the total target quantity and the current total quantity;
determining via the control unit a residual mass of the cargo load to remain in the reception unit based on a second difference between the initial mass and the first difference;
adjusting via the control unit a tipping angle of the reception unit to a defined initial angle;
determining via the weighing device a current mass of the cargo load in the reception unit when the tipping angle is less than a defined maximum tipping angle, which is less than a mechanical end-stop of the reception unit;
shaking via the control unit the reception unit for a defined shaking duration when the current mass is greater than a sum of the residual mass and a tolerance mass;
modifying via the control unit at least one of the defined shaking duration and the tipping angle based on a third difference between the shaking mass and a defined mass limit value when the shaking mass is less than the defined mass limit value; and
determining via the control unit whether the current mass is less than or equal to the sum of the residual mass and the tolerance mass when the tipping angle is less than the defined maximum tipping angle.

6. The method of claim 5 , wherein the control unit modifies the defined shaking duration and increases the tipping angle based on the third difference between the shaking mass and the defined mass limit value when the shaking mass is less than the defined mass limit value.

7. The method of claim 5 , further comprising:
reducing the tipping angle to the defined initial angle when tipping angle is greater than or equal to the defined maximum tipping angle.

8. The method of claim 5 , further comprising:
reducing the tipping angle to the defined initial angle when the current mass is less than or equal to the sum of the residual mass and the tolerance mass.
