Embodiment Construction

[0076] figure 1 and figure 2 The schematic structure of a device for forming a parison 1 into a container 2 is shown in . This arrangement can be realized here as shown or in a vertical plane rotated by 180°.

[0077] The molding plant for the container 2 basically comprises a blow molding station 3 provided with a blow mold 4 into which the parison 1 can be inserted. The parison 1 can be an injection molded part made of polyethylene terephthalate. In order to be able to insert the parison 1 into the blow mold 4 and to be able to remove the finished container 2, the blow mold 4 comprises mold halves 5, 6 and a base part 7 which can be positioned by a travel device 8 . The parison 1 can be held by holding elements 9 in the region of the blow molding station 3 . The retaining element 9 can be designed, for example, according to the invention or as known from the prior art. For example, it is possible to insert the parison 1 directly into the blow mold 4 by means of clamps...

Abstract

The invention relates to a heating device (H) having at least one heating section (24) for thermally adjusting a parison (1) made of thermoplastic material to a temperature profile suitable for blow molding, wherein the heating device (H) has a conveying device for conveying the parisons (1) along the conveying path (T) of the heating device (H), wherein the conveying device has handling means for holding and manipulating the individual parisons (1) (39), wherein the conveying device is constructed and set up such that the parisons (1) are guided in a unique arrangement in at least one first section of the conveying path (T), and in at least one first section of the conveying path (T) It is guided in two adjacent arrangements in a second section.

Description

technical field [0001] The invention relates to a heating device for thermally regulating parisons intended for blow molding, a blow molding machine, and a method for conveying parisons made of thermoplastic material. Background technique [0002] In container molding by means of blow molding pressure, parisons made of thermoplastic material, for example PET (polyethylene terephthalate), are molding and manufacturing of finished containers made from parisons) to the different processing stations. Typically, such a blow molding machine (or blow molding machine) has a heating device and a blow molding device in the region of which the preforms previously tempered in the heating device are expanded into containers by biaxial orientation. This expansion takes place, for example, by means of compressed air which is introduced into the parison to be expanded. The technical sequence of the method for such an expansion of the parison is explained, for example, in document DE 43 40...
