15 Claims

1. A mould system for moulding a blade shell of a wind turbine blade, the mould system comprising a first mould for manufacturing a first blade shell part of the wind turbine blade and a second mould for moulding a second blade shell part of the wind turbine blade,

wherein the first mould has a first moulding side with a first moulding surface that defines an outer shape of the first blade shell part,

wherein the second mould has a second moulding side with a second moulding surface that defines an outer shape of the second blade shell part,

wherein the mould system is configured to rotate and position the first mould such that the first moulding side is facing the second moulding side and such that the first blade shell part may be joined with the second blade shell part so as to form the blade shell of the wind turbine blade,

wherein the first mould comprises a first mould flange along at least a part of the periphery of the first moulding surface, the first mould flange being configured to provide a first shell part flange along at least a part of the periphery of the outer shape on the first blade shell part,

wherein the mould system further comprises one or more fastening elements attachable to the first mould and being configured to secure the first blade shell part to the first mould during rotation and positioning of the first mould, the one or more fastening elements including a first fastening element being configured to secure the first blade shell part to the first mould at a first fastening position along the first mould flange,

wherein the mould system further comprises a measurement arrangement comprising one or more measurement units including a first measurement unit, wherein the measurement arrangement is configured to measure displacement of the first shell part flange relative to the first mould flange, wherein the first measurement unit is configured to measure displacement of the first shell part flange relative to the first mould flange at a first measurement position along the first mould flange, and

wherein the mould system further comprises a processing unit configured to receive data from the one or more measurement units, the data received from the one or more measurement units comprising data received from the first measurement unit comprising a first displacement value indicative of the displacement of the first shell part flange relative to the first mould flange at the first measurement position, and wherein the processing unit is configured to:

determine whether the first displacement value is above or equal to a first displacement limit; and

in accordance with the first displacement value being above or equal to the first displacement limit, outputting a first notification by an output unit.
