Problems solved by technology

In this case, the problem is the control of the nominal flow rate of the cooling air flow, which must be very precise
In particular, blowers may lose efficiency over time and blower operation
Likewise, filters can clog
As a result, the rated flow rate of the air flow produced by each blower does not meet the requirements, defects of the container after blow molding are regularly observed at the outlet of the device

Embodiment Construction

[0049] The present invention relates to thermal conditioning of preforms 1 in the context of the manufacture of plastics material containers obtained by transforming preforms 1 by a stretch blow molding operation.

[0050] Preferably, but not limitatively, the plastic material may be of any type, preferably PET (polyethylene terephthalate).

[0051] The container takes the form of an ampoule or flask and is made of rigid or semi-rigid plastic material. The container is intended to be used in a non-exhaustive manner as a container for fluids, liquids, powders or granules, especially for agri-food, cosmetic type fluids, liquids, powders or granules dedicated to maintenance or personal hygiene.

[0052] Such containers can be subjected to several different sequential processes: from the manufacture of containers by means of preforms 1 by blow or stretch blow moulding operations, in particular through filling, capping, labelling of products in units, up to batches Pack groups of ...

Abstract

The invention relates to a device (2) for thermally conditioning preforms (1), comprising a heating module (3) provided with: a housing (4) having a transport space (40) for transporting the preforms (1); a heating member (5) and a cooling member (6) both oriented towards the space (40); a control means (9) for controlling the heating and cooling means (5, 6); the cooling means comprise: a circulation means (7) for circulating an air flow at a rated flow rate determined by the control means (9); a channel (8) between the circulation member (7) and the housing (4) and opening into the space (40); the invention is characterized in that the thermal regulation device comprises an actual flow rate measuring means (10) along the channel (7) and a regulating means (11) for regulating the target flow rate relative to the actual flow rate by controlling an actuating means (9). The invention also relates to a corresponding thermal conditioning method.

Description

technical field [0001] The invention belongs to the field of the manufacture of plastics material containers obtained by converting preforms by means of a blow-molding operation. [0002] Preferably, but not limitatively, the plastic material may be PET ("polytéréphtalate d'éthylèhe (abbreviation for polyethylene terephthalate)"). Background technique [0003] The container takes the form of an ampoule or flask and is made of rigid or semi-rigid plastic material. The container is intended to be used in a non-exhaustive manner as a container for fluids, liquids, powders or granules, especially for agri-food, cosmetic type fluids, liquids, powders or granules dedicated to maintenance or personal hygiene. [0004] It is well known that in industrial production lines, containers can be subjected to several different sequential processes: from the manufacture of containers by blow or stretch blow molding operations, in particular through filling, capping, labelling of products b...
