Method and apparatus for producing plastic preforms and plastic containers with thermal preform storage

An apparatus for producing plastic preforms and plastic containers, comprising at least one injection moulding machine for injection moulding the plastic preforms and a blow moulding machine for forming the plastic preforms into plastic containers, wherein the injection moulding machine and the blow moulding machine can be coupled to one another and with a transport device for transporting the plastic preforms from the injection moulding machine to the blow moulding machine, wherein the apparatus further comprises a heating device arranged downstream of the injection moulding machine, within which the plastic preforms can be heated to a temperature necessary for the blow moulding, characterised in that

• the plastic preforms produced in the injection moulding machine are transferred directly after production to a thermal preform storage which keeps the plastic preforms at a predetermined constant temperature and wherein a sensor device is provided between the thermal preform storage and a heating device for heating the plastic preforms, which measures a value of a preform which is characteristic of the energy content, wherein this value being transferred to a control device with which a speed and/or at least one parameter of at least one subsequent treatment device is regulated, wherein the preforms are not actively heated within the thermal preform storage by means, but are kept at the temperature at which they are fed into the thermal preform storage, so that an inlet temperature of the preforms into the thermal preform storage corresponds to an outlet temperature of the preforms from the thermal preform storage.
