Abstract

The present disclosure relates to a method for operating a pharmacy order-picking device. The present method reduces the susceptibility of the pharmacy order-picking device to disruption. To detect a positioning deviation of the control appliance in the horizontal direction, at least one desired value of at least one reference position is made available, the control appliance is brought to a position corresponding to the desired value in the horizontal direction and, when a signal characteristic of a reference position is detected, an actual value of this reference position is determined. A desired value is compared with a corresponding actual value, or two actual values are compared with each other, and a deviation is determined. If a deviation is determined that exceeds a limit value, a signal pointing to the need for a correction is output. Depending on the deviation, automatic correction of the position deviation can be performed.

Dependent claims

A method for operating a pharmacy order-picking system, the method comprising:

providing the pharmacy order-picking system comprising:
at least one shelf unit each having a plurality of shelves extending in a horizontal direction (X axis) and a plurality of shelf walls extending in a vertical direction (Z axis),
at least one operating unit that can be moved horizontally and vertically in front of the shelf unit, having a gripping device for placing drug packages on the shelves and retrieving the drug packages from the shelves, whereby the operating unit comprises:
at least one sensor and
a control unit that is connected to the operating unit,
detecting a positioning deviation of the operating unit in the horizontal direction (X axis), the detecting comprising:
a) providing at least one setpoint value of at least one reference position,
b) approaching, with the operating unit, in the horizontal direction, a reference position of the at least one reference position corresponding to a setpoint value of the at least one setpoint value,
c) determining, on detection of a signal that is characteristic of the reference position, an actual value of the reference position,
d) comparing the setpoint value with the corresponding actual value or comparing two actual values with one another and determining a horizontal deviation, and
e) if the horizontal deviation exceeds a limit value, outputting a signal indicating a need for a correction.

A machine-implemented method for detecting a positioning deviation of an operating unit in a pharmacy order-picking system, the method comprising:

accessing a setpoint value corresponding to a reference position, the reference position comprising a physical location in the pharmacy order-picking system;
approaching, using the operating unit, in a horizontal direction, the reference position;
detecting a signal that is characteristic of the reference position;
ascertaining an actual value of the reference position;
comparing the setpoint value with the actual value;
determining a horizontal deviation based on the comparison of the setpoint value and the actual value;
and
if the horizontal deviation exceeds a threshold value, outputting a signal indicating a need for a correction.
