A blow molding apparatus for expanding plastic preforms into plastic containers may include a blow piston extending in a longitudinal direction and a blow nozzle extending from the blow piston in the longitudinal direction. The blow nozzle may be configured to apply a gaseous medium to a preform for the expansion thereof. A connection device may be structured and arranged to supply the gaseous medium to the blow molding apparatus via at least two connection lines, and a control block may be arranged between the connection device and the blow piston. The control block may be configured to control the supply of the gaseous medium during the expansion process using at least partially varying pressure levels and may have a plurality of channels for guiding the gaseous medium. The plurality of channels may be separated from each other at least in sections and may be distributed in a circumferential direction of the control block. At least two valves may be on an outer circumference of the control block. The valves may be distributed in a circumferential direction around the control block, and may be controlled independent of one another for controlling the supply of the gaseous medium to the blow nozzle. A distribution member may be configured to guide the gaseous medium into said channels. The distribution member may be arranged between the connection device and the control block if viewed in the flow direction of the gaseous medium. The channels may extend within the control block at least in sections substantially parallel to the longitudinal direction of the blow piston.

In a quick-change system for exchangeable machine elements, particularly in a container processing machine in which the machine element (E) can be brought into a target position and can be localized in a target position by a securing unit comprising at least one securing element, at least a second securing unit (P2) is provided with which a machine element that either has not been brought into the target position or that has moved out of the target position (X) can be localized in a securing position. The securing position is detected and evaluated as grounds for a corrective action before commencing an operation or during the operating sequence before a corrective action is initiated and executed.
摘要:
A device for moulding plastic preforms into plastic containers may include at least one blow station having a first mould part and a second mould part. The first mould part and the second mould part surround a cavity within which the plastic preforms may be expanded into plastic containers. The first mould part may be movable relative to the second mould part. The device includes a first cantilever which is disposed on the first mould part, a second cantilever which is disposed on the second mould part, a first hinge lever which is hingedly connected to the first cantilever, and a second hinge lever which is hingedly connected to the second cantilever. The first cantilever and the second cantilever may be arranged to be pivotable with regard to at least one geometrical pivot axis and may be coupled to an actuating device which causes a movement of the first cantilever and of the second cantilever for moving the mould parts. The blow station may be mounted on a transport via a carrier. The carrier may extend through a geometrical plane which is delimited by the cantilevers and the hinge levers and/or the geometrical arrangement of the cantilevers and the hinge levers may be arranged to be asymmetrical with regard to a geometrical centre line of the blow station.
