Problems solved by technology

[0014] However, the models directly adjacent to the transfer point are out of reach: the conveyor must be pivoted to release the models
However, this rotation is dangerous since the gripping member risks breaking due to the above reasons

Embodiment Construction

[0042] In particular, the drawing shows a container production plant 1 for producing containers 2 from plastic blanks 3 . According to an embodiment shown in the figures, the blank 3 is a preform directly from injection moulding. In other embodiments, however, the blank 3 may be an intermediate container that has undergone one or several prefabrication operations, such as preblowing. An example of a plastic is polyethylene terephthalate (PET).

[0043] The plant 1 firstly comprises a blow molding machine 4 equipped with a rotating conveyor 5 and a plurality of molding stations 6, each molding station comprising a mold M mounted on the conveyor 5, which can be in:

[0044] - an open position for allowing the blank 3 to enter and exit the formed container 2; and

[0045] - A closed position for allowing the container 2 to be formed from the blank 3 .

[0046] According to an embodiment shown in the accompanying drawings, in particular image 3 , each model M comprising two m...

Abstract

Disclosed is a maintenance method for an installation for production of containers from blanks made of plastic material, which includes: a blow-molding machine including a rotating carousel and a plurality of forming stations, each including a mold; a primary power unit connected to the carousel; a transfer device suitable for inserting a blank into a mold or for withdrawing a container therefrom;and a secondary power unit connected to the transfer device. The method includes the detection of a misalignment of the transfer device with the carousel, and, therefore, operations for desynchronization of the power units, for realigning and then for resynchronization of the transfer device and of the carousel.

Description

technical field [0001] The invention relates to the production of containers from blanks made of plastic, such as PET. More precisely, the invention relates to the overhaul of container production equipment. Background technique [0002] Container production plants traditionally consist of a blow molding machine equipped with a rotating conveyor and a plurality of molding stations, each forming station comprising a mold mounted on the conveyor. [0003] Each model can be in an open position that allows (preheated to a temperature above the glass transition temperature of the material, which in the case of PET is about 80°C) the blank to enter, and a closed position that allows The container is formed from the blank by injecting a pressurized fluid, typically air, into the blank. The opening and closing of each model is generally ensured by a cam-controlled linkage. [0004] The conveyor is driven in periodic rotational motion by a first motorisation; for example a coupled...
