Abstract:
In an apparatus for shaping plastics material pre-forms into plastics material containers, the blow mould comprises a first mould part and a second mould part, the blow mould comprises a base part which is movable with respect to the mould parts along a lifting direction extending parallel to the longitudinal axis of the mould parts, in order to close off a cavity, in the closed setting, in the lifting direction, and wherein a plastics material pre-form is capable of being directly acted upon with pressure by a gaseous medium inside the cavity, wherein at least one second drive device which is designed in the form of an electric linear drive is set up and provided to move the base part relative to the mould parts in the lifting direction.
Abstract:
Described is a container treatment device for the expansion of pre-forms into containers, having at least one blow moulding device for the introduction of a flowable medium under pressure into an inner space of the pre-form, and at least one stretching device for stretching the pre-form during an expansion procedure. The blow molding device has at least one blow molding nozzle piston and the stretching device has at least one stretch rod which is movable at least locally and at least for a time through a through opening of the blow molding nozzle piston in a translational manner and which is operatively connected to at least one portion of a stretch rod drive device, wherein at least one bearing element is arranged in the region of the through opening in order to guide the stretch rod.
Abstract:
A blowing mould array includes a blowing mould unit forming a cavity, inside of which plastic preforms are expanded to plastic containers. The blow mould unit includes a blowing mould retainer having at least two mould retainer elements for accommodating parts of the blowing mould unit, and a locking mechanism to arrest at least one part of the blowing mould unit against at least one mould retainer element. The locking mechanism includes an engagement element that can be pivoted and/or shifted relative to a default axis, which in an arrested state abuts a segment of a part of the blowing mould unit. The locking mechanism has an actuating element to loosen the arrest between the mould retaining element and the blowing mould unit. Actuation of the actuating element is coupled with actuation of the engagement element.
Abstract:
The invention relates to a device (100) for sterilizing plastic parisons (1), with a sterilization chamber (3) and a transport device (2) disposed at least partially inside the sterilization chamber (3) for moving the plastic parisons (1) within the sterilization chamber (3), wherein the transport device (2) has at least one gripping system (4) for engaging round and supporting the plastic parisons (1) by means of a gripping clamp (41), wherein the gripping system (4) has a displacement means (5) for displacement during sterilization within the sterilization chamber of contact surfaces (1A) of the plastic parisons (1) which are shielded by the gripping system (4) from a sterilizing medium and/or sterilizing radiation.
Abstract:
A container treatment plant and a method for the treatment of containers are described. The container treatment plant includes a plurality of treatment elements, wherein each treatment element is used for a pre-determined treatment of the containers and each treatment element has associated therewith a container nominal value which indicates which type of container the treatment element can treat, a detection device for detecting properties of one of the containers to be treated, and a comparator device for comparing a detection result of the detection device with the container nominal value for at least one treatment element.
