Embodiment Construction

[0067] The principle structure of the equipment for forming the preform 1 into the container 2 is in figure 1 neutralize figure 2 Shown in. Here, the assembly can be realized as shown or realized in a manner rotated by 180° in a vertical plane.

[0068] The equipment for forming the container 2 basically includes a blow molding station 3 provided with a blow molding mold 4 into which the preform 1 can be placed. The preform 1 may be an injection molded part made of polyethylene terephthalate alcohol. In order to enable the preform 1 to be inserted into the blow mold 4 and to enable the completed container 2 to be taken out, the blow mold 4 includes mold halves 5, 6 and a bottom part 7, which can be positioned by a lifting device 8. . The preform 1 can be fixed in the area of ​​the blow molding station 3 by holding elements 9. For example, it is possible to insert the preform 1 directly into the blow mold 4 by means of pliers or other operating devices. In order to supply com...

Abstract

A heating device having at least one heating section for thermally conditioning preforms made of thermoplastic material to a temperature profile suitable for blow molding, having a conveyance for conveying the preforms along a conveying path of the heating device The conveying device comprises a revolving conveyor chain having a plurality of hingedly interconnected links, the conveying device has handling means for holding and holding each individual preform, and the conveying device is configured such that the preform is in the conveying path Guided in a single row in the first section and in an adjacent double row in the second section, each chain link has a suspension on which the first and second operating means are arranged , the suspension has a main arm and a pivot arm pivotably connected to the main arm, and the conversion between single-row and double-row conveyance of preforms can be realized through the pivoting of the pivot arm.

Description

Technical field [0001] The present invention relates to a heating device and a blow molding machine. The heating device is used for thermally modulating a preform set for blow molding. Background technique [0002] When the container is formed by blow molding pressure, a preform made of a thermoplastic material, such as a preform made of PET (polyethylene terephthalate alcohol), is used in the blow molding machine. In the equipment that manufactures finished containers by blow molding the preforms, they are led to different processing stations. Typically, this type of blow molding machine or blow molding machine has a heating device and a blow molding device, in the area of ​​the blow molding device, the preforms that have been previously temperature-controlled in the heating device are biaxially oriented. Expand into a container. The expansion is carried out, for example, by means of compressed air introduced into the preform to be expanded. The technical sequence of the meth...
