Embodiment Construction

[0032] Hereinafter, elements having the same structure or similar functions will be denoted by the same reference numerals.

[0033] In the following, the longitudinal direction oriented in the direction of movement of the preforms along its transport path, the vertical direction oriented in the direction of gravity, and the transverse direction represented by the coordinate system L, V, T in the figure are used in a non-limiting manner.

[0034] In the following, the terms "upstream" and "downstream" will be used with reference to the direction of movement of the preforms along their production flow, in particular along their transport path.

[0035] figure 1 A heating station 10 for heating preforms 12 made of thermoplastic material is shown in . The heating station 10 belongs to a manufacturing facility (not shown) for manufacturing containers of thermoplastic material by shaping preforms 12 , notably by stretch blow moulding.

[0036] The heating station 10 comprises a c...

Abstract

The invention relates to a method for managing captive preforms (12) immobilised in a heating station (10) during an interruption in production, the heating station (10) comprising: a device (14) for conveying preforms (12), comprising individual supports (16) circulating in a closed circuit;and a heating cavity (30) with at least one row of monochromatic electromagnetic radiation emitters (32) around the edge thereof; characterised in that the method comprises a step (E3) of heating, by the emitters (32) of the heating cavity (30), so-called "cold" captive preforms that have been immobilised before having been exposed to the electromagnetic radiation emitted by the emitters (32).

Description

technical field [0001] The invention relates to a management method for managing stagnant preforms immobile in a heating station during production interruptions. Background technique [0002] The invention is intended to be practiced in container manufacturing facilities for the manufacture of preforms made of thermoplastic material, especially polyethylene terephthalate (PET), especially by blow molding or stretch blow moulding. container. This facility allows for very high volume production of containers at very high rates. [0003] It is known to manufacture containers of thermoplastic material such as polyethylene terephthalate (PET) by preform forming methods. [0004] According to known techniques, such containers are produced in two main steps. [0005] In a first step, a PET preform is molded by injection. The preform comprises a generally tubular body closed at one of its axial ends, the opposite end being open by a neck. From this injection molding operation, ...
