Abstract:
The invention relates to a system for transforming plastics material preforms into plastics material containers having a plurality of blow molding stations which are arranged on a carrier and in each case comprise a blow mold for expanding plastics material preforms into plastics material containers inside this blow mold by means of a pressurized pneumatic medium which is supplied to the respective blow molding station via a pressure supply device and which is at least partially extracted again from the respective blow molding station after the expansion operation via a pressure extraction device. According to the invention it has an energy conversion device, with the aid of which at least part of the potential energy stored in an energy store can be turned into an increase in the potential energy of a pneumatic medium associated with at least one blow mold, wherein the energy conversion device has an intermediate energy storage device, and at least part of the potential energy extracted from the energy store, and the energy transmitted by the energy conversion device, can be stored in the form of kinetic energy in the intermediate energy storage device.
Abstract:
Provided is a method for calibrating at least one processing element, in a processing station for processing plastic preforms, includes providing: a first measurement preform establishing at least one first measurement value of the measurement preform before processing by the processing station, and a second measurement value of the measurement preform is measured by the measuring element or a further measuring element before or after processing by the processing station, and using at least these two measurement values, a mathematical temperature curve, is recorded by the measuring element, wherein at least one calibration device determines a deviation of the measured temperature curve from a mathematical standard temperature curve, and eliminates this deviation at least partially by adaptation of processing parameters of the processing station.

The container treatment device is arranged to treat the containers transported by the transport device and the holding element is rotatable such that the container held by the holding element is rotatable with respect to its longitudinal direction and the container treatment apparatus includes a monitoring device for monitoring the rotational movement of the containers.
Abstract:
A method and a device for buffering containers in a container treatment plant. According thereto, containers are put into storage in a grouped manner in single file on at least one input conveyor belt, are moved in single file on a transversely adjoining buffering surface of shuttles, guided and driven individually on rails, having row pushers, in a buffering direction extending transversely to the input direction, and are taken out of storage on at least one output conveyor belt. Since, furthermore, containers are taken out of storage from the buffering surface by branching conveyor belts integrated in the buffering surface, transversely to the buffering direction and independently of the input conveyor belt and output conveyor belt, and/or are put into storage on the buffering surface, it is possible for container flows to be distributed flexibly and combined on the buffering surface.
