Method and apparatus for blow molding and for filling containers

摘要

The method and the apparatus are used for blow molding and for filling containers. To this end, after a thermal conditioning step, a preform is shaped into a container using blowing pressure inside a blow molding tool. The blow molded containers are positioned at least along part of the transport path thereof by a carrying element, which is held by a rotating transfer wheel. The transfer wheel provides at least part of a coupling between a blow molding module for producing the containers and a filling module for filling the containers. An outfeed wheel of the blow molding module can be arranged in a transport direction of the containers upstream of the transfer wheel, and an infeed wheel of the filling module can be arranged in said transport direction downstream of the transfer wheel, wherein each wheel can be equipped with carrying elements for the containers. The number of carrying elements (42) in the region of the transfer wheel (41) is varied in accordance with a production speed.

主权项

1. A method for blow molding and for filling containers, comprising the steps of: initially thermally conditioning a preform; subsequently shaping the preform within a blow mold by influence of compressed air in the preform; positioning blow molded containers at least along a portion of a transport path by a support element that is held by a rotating transfer wheel, the transfer wheel making available at least a section of a coupling between a rotating blow molding module for manufacturing containers and a rotating filling module for filling containers; and changing a number of support elements on the transfer wheel by removing support elements from or adding support elements to the transfer wheel in dependence on a production speed when a relative rotational speed of the blow molding module and the filling module is changed.
