Embodiment Construction

[0046] Other advantages, features and characteristics of the present invention will become apparent in the following detailed description of embodiments with reference to the accompanying drawings. However, the present invention is not limited to these Examples.

[0047] The principle structure of a device for forming a preform (1) into a container (2) is in figure 1 neutralize figure 2 shown in . The arrangement here can be realized as shown or rotated by 180° in the vertical plane.

[0048] The plant for the shaping of the containers (2) essentially consists of a blow molding station (3) provided with blow molds (4) into which the preforms (1) can be placed . The preform (1) can be an injection molded part from polyethylene terephthalate. To enable the preform (1) to be placed into the blow mold (4) and to enable the removal of the finished container (2), the blow mold (4) comprises mold halves (5, 6) and a bottom part (7) , said bottom part can be positioned by a lif...

Abstract

The invention relates to a transport system for transporting preforms in a device for the blow-moulding production of finished containers, wherein the transport system comprises a transport chain, thechain elements of which have a support element for transporting the preforms, wherein the support element comprises a shaft part and a head part, and the head part has a head end region that can be introduced into the opening section of the preform, characterised in that the head part is retained on the shaft part and can be detached from the shaft part via actuation of a first actuation element,wherein the first actuation element is arranged in the end region of the shaft part facing away from the head part. The invention also relates to a device for the blow-moulding production of finishedcontainers from preforms, a use, as well as a method for exchanging at least one head part, each making use of the transport system according to the invention.

Description

technical field [0001] The invention relates to a conveying system for conveying preforms in a plant for blow molding finished containers, wherein the conveying system comprises a conveying chain whose links comprise load-bearing Components and Shipping Components. Furthermore, the invention relates to a device for blow-molding finished containers from preforms, as well as a use of the conveyor system and a method for exchanging at least one carrier element of the conveyor system. Background technique [0002] For the packaging of liquid food and beverages, containers, for example bottles made of glass or plastic, are generally used, which are made at different plants during the manufacturing process and are subsequently filled in other plants. For example, the production of containers from plastic in blow molding plants is mentioned here. When forming containers by means of blow molding pressure, preforms made of thermoplastic material, for example PET (polyethylene terep...
