Abstract
A device for manufacturing plastic containers, including a clocked preform manufacturing means, a temperature control means for thermal conditioning preforms manufactured in the preform manufacturing means, and a continuously working blow molding machine, where the temperature control means is designed and/or configured such that preforms that have been manufactured in one cycle of the preform manufacturing means can be differently temperature controlled.
Claims11
Device for manufacturing plastic containers, comprising a clocked preform manufacturing means, a temperature control means for thermal conditioning of preforms manufactured in the preform manufacturing means, and a continuously working blow molding machine, wherein the temperature control means is designed and/or configured such that preforms that have been manufactured in one cycle of the preform manufacturing means can be differently temperature controlled,
- the device further comprising a buffer storage for preforms, wherein the buffer storage is arranged between the preform manufacturing means and the temperature control means, wherein the buffer storage is heat-insulated.
Method of manufacturing plastic containers in a device for manufacturing plastic containers, having a clocked preform manufacturing means, a temperature control means for thermal conditioning preforms manufactured in the preform manufacturing means, and a blow molding machine, comprising:
- manufacturing a predetermined number of preforms in the clocked preform manufacturing means;
- and
- introducing the predetermined number of preforms into the temperature control means for thermal conditioning the preforms, wherein the preforms are differently temperature controlled in the temperature control means;
- and
- stretch blow molding of the preforms in the blow molding machine to obtain plastic containers,
- wherein in case of a malfunction of the blow molding machine, the preforms manufactured by the clocked preform manufacturing means are introduced into a heat-insulated buffer storage.
Method of manufacturing plastic containers in a device for manufacturing plastic containers, having a clocked preform manufacturing means, a temperature control means for thermal conditioning preforms manufactured in the preform manufacturing means, and a blow molding machine, comprising:
- manufacturing a predetermined number of preforms in the clocked preform manufacturing means;
- and
- introducing the predetermined number of preforms into the temperature control means for thermal conditioning the preforms, wherein the preforms are differently temperature controlled in the temperature contorl means;
- and
- stretch blow molding of the preforms in the blow molding machine to obtain plastic containers;
- wherein in the case of a malfunction of the blow molding machine, the preforms manufactured by the clocked preform manufacturing means are introduced into a buffer storage;
- wherein after a malfunction of the blow molding machine has been removed, operating the blow molding machine at reduced power until all preforms stored in the buffer storage have been processed.
