Embodiment Construction

[0079] figure 1 A schematic diagram of an apparatus for heating plastic parisons is shown. The plastic parisons 10 are individually fed into the device 1 via a feed rail 52 and a single clock turntable 54 . exist figure 1 The unit for generating the pitch delay is not shown in the view shown in , however, the single clock turntable can not directly transfer the plastic parisons to the first conveying device 2 (eg figure 1 shown), instead the plastic parisons are transferred to another conveying device 4, which is shown in the following figures.

[0080] The plastic parisons are conveyed through the apparatus 1 by means of the conveying device 2 and during this process the plastic parisons are conveyed past and heated by a plurality of heating assemblies 14 . At the same time, the plastic parison is rotated about its longitudinal direction. Reference numeral 16 designates a cooling assembly, which cools the plastic parison 10 or its outer surface by means of cooling air. R...

Abstract

A device (1) for processing plastic parisons (10), having a first conveying device (2) for conveying plastic parisons (10) along a predetermined conveying path (T) at a first predetermined pitch (Te1), in plastic At least one heating assembly for at least sometimes heating the plastic parisons (10) during conveyance of the parisons (10) and a second heating element arranged downstream relative to the first conveying device (2) in the direction of conveyance of the plastic The conveying device (6), the second conveying device comprises a plurality of holding assemblies (62) for holding plastic parisons (10) and is adapted and designed to vary the pitch between successive plastic parisons. According to the invention, the device (1) comprises a further conveying device arranged at least partially in the conveying direction of the plastic parisons between the first conveying device (2) and the second conveying device (6), wherein between the plastic parisons The pitch between is changed.

Description

technical field [0001] The invention relates to a device and a method for processing plastic parisons. Background technique [0002] It is known in the prior art to manufacture plastic containers by first heating plastic parisons in an oven and then converting the plastic parisons in their heated state by means of a transformation device, such as a stretch blow molding machine. In this furnace, the plastic parisons are normally transported through very small gaps between the plastic parisons or at very small pitches. This pitch may be, for example, 38 mm. In contrast, a subsequent conversion device requires a larger pitch of eg 445 mm, because the individual conversion tables are rather large in size. [0003] It is therefore known in the prior art to use so-called pitch delay turrets between the furnace and the conversion table, which increase the pitch between successive plastic parisons. This technique works well for smaller conveying and working speeds, but has its li...
