System and method for carrying out a changeover process in a beverage production plant

A method for carrying out a changeover process in a system for producing beverage containers, wherein this system in operation produces plastic containers from plastic parisons by a transforming device and these produced containers are transported to a filling device and the containers are filled with a liquid, wherein at least the transforming device and the filling device are at least intermittently in data communication, comprising the steps of:

• outputting a time value based on a time-dependent changeover status of the transforming device or the filling device;
• and
• carrying out the changeover process of at least the transforming device or the filling device according to a predetermined time sequence based on the time value, wherein the time value comprises at least one of a group selected from a length of time necessary for heating a plurality of blow moulds, a time period over which heating of the transforming device or filling device has already taken place, a countdown for heating of the transforming device or filling device, and a running time period during which the at least the transforming device or the filling device will remain heated;
• carrying out a conversion process at least on the transforming device and/or the filling device, wherein at least one element of this transforming device and/or the filling device is changed;
• upon receiving a first input indicating an end of the conversion process, heating to a first operating temperature:
• the plurality of blow moulds from time T1 to a time T4, heating to a second operating temperature a flash heater from time T2 to a time T4, and heating to a third operating temperature the filling device from time T3 to a time T4, wherein the first, second and third operating temperatures are temperatures at which the plastic parisons are producible or fillable, wherein T1<T2<T3<T4, wherein at time T4 the plurality of blow moulds, the filling device and the flash heater are ready for production of the beverage containers, wherein T4−T1 is a minimum amount of time necessary to heat the plurality of blow moulds to the first operating temperature, wherein T4−T2 is a minimum amount of time necessary to heat the flash heater to the second operating temperature, wherein T4−T3 is a minimum amount of time necessary to heat the filling device to the third operating temperature.
