Embodiment Construction

[0063] The technical solutions of the present invention will be further described below in conjunction with the examples, but the present invention is not limited thereto.

[0064] figure 1 A device 1 for producing plastic containers according to the invention is schematically shown. The device has a conveyor device 2 (shown only schematically) in the form of a blow molding wheel, wherein a plurality of blow molding stations 4 for expanding the preforms are distributed over the blow molding wheel. Reference numeral 20 designates a control device or servo converter respectively assigned to the individual blow molding stations. The individual control devices 20 are thus distributed (rotatably) over the blow molding wheel 2 . The power supply of the control device takes place via a slip ring designated with reference numeral 6 and a connecting line 11 .

[0065] Each blow molding station 4 has a drive 16 for a crossbar (not shown) and valves 12 which control the actual blow mo...

Abstract

The device (1) has a blow mold (3) within a plastic preform expanded to plastic containers by using gaseous medium. A drawing bar is provided for extending the plastic preform along a longitudinal direction. The blow mold has an information carrier e.g. radio frequency identification chip, and information reading unit (7) for reading the information carrier. The information carrier is designed such that characteristic features for geometric parameter of the containers are determined by interaction between the information carrier and the information reading unit. The characteristic features are container volume, extension, conversion process, container geometry, color of plastic preform, diameter of plastic preforms, weight of the blow mold, cross-sectional area of the mold, an indication of hours of operation. An INDEPENDENT CLAIM is also included for a method for molding a plastic preform to a plastic container.

Description

technical field [0001] The invention relates to a plant for processing plastic preforms into plastic containers. Background technique [0002] Devices have long been known from the prior art in which plastic pre-forms are introduced into blow molds and expanded into plastic bottles by means of supplied compressed air. Furthermore, the process parameters for forming the plastic pre-forms are selected in different ways depending on the individual pre-form and the plastic container to be produced. Therefore, different pressures are usually applied to the plastic pre-forms in a certain sequence. This sequence is not only relevant to the preform itself, but also to the individual blow molds. [0003] On the part of the user, it is sometimes desired to perform an exchange of the device, ie to switch from one bottle type to another. This makes it possible, for example, to exchange the blow mold or to provide another preform. However, if the process parameters are not suitable f...
