HANDLING PLANT AND HANDLING METHOD FOR PRODUCT CONTAINERS

The invention relates to a handling system for product containers, having a transporter for transporting the product containers and having at least one container handling machine which comprises a handling assembly for handling the product containers, wherein the container handling machine comprises a plurality of interchangeable fitting parts for processing different product types and receptacle locations provided therefor, and wherein the interchangeable fitting parts comprise first data transponders having first identification data for identification, wherein the handling system comprises a line management system which, for processing the different product types, is designed to provide to the at least one container handling machine a production order having a configuration list in each case, wherein the configuration list comprises a selection of the interchangeable fitting parts provided for the processing of the particular product types, and wherein the handling system comprises a reader.

PRODUCTION SYSTEM

In a production system 100, containers have hollow main bodies 1a having openings at their top parts and caps 1b for closing the openings. The production system 100 includes a conveyor line L for conveying the containers 1, a capper 5 for attaching the caps 1b to the main bodies 1a of the containers 1 on the conveyor line L, a reading apparatus 18 configured to read first information attached to top surfaces of the caps 1b of the containers 1 for identifying the containers 1 on the conveyor line L at one or more predetermined points after the capper 5, and a memory apparatus 52 configured to store linked together the first information of the containers 1, second information attached to the main bodies 1a of the containers 1 for identifying the main bodies 1a, and times at which the containers 1 passed the one or more predetermined points.

PREFORM LAYERED BODY AND LAYERED CONTAINER

The disclosure provides a preform layered body and a layered container produced by biaxial stretch-blow forming of the layered body. In this preform layered body, an RFID tag has been inserted between an inner-layer-use mouth part and an outer-layer-use mouth part that are to remain unaltered, with no biaxial stretch-blow forming performed thereon, as a container mouth part for a layered container. Since the container mouth part does not become exposed to the high temperature and high pressure for stretch-blow forming purposes, abuses to the RFID tag, such as damage, breakage, and deformation, which arise from the heating, pressurization, and stretching during the stretch-blow forming, can be avoided reliably. In addition, labor-saving and counterfeit prevention effect can be anticipated by causing the RFID tag to hold product information.

Method and apparatus for forming plastic preforms for plastic containers with curve evaluation

Method for forming plastic preforms into plastic containers, wherein a plastic preform is introduced into a blow mould and is expanded into a plastic container by being applied by a flowable medium, wherein the plastic preform is applied by at least two different pressure levels and wherein furthermore preferably a rod-like body is introduced into the plastic preform, in order to expand the plastic preform in its longitudinal direction, wherein a pressure curve and/or a movement curve of the rod-like body being determined by a measuring device during the expansion process, wherein least one of the curves is evaluated by means of a processor device and at least one point or region of this curve which is characteristic of the course is determined.
