Embodiment Construction

[0032] figure 1 A plant 1 for the production and further processing of plastics material pre-forms or plastics material containers is shown. In this case, the plant has a conveying device which is broadly and schematically denoted 2 as a whole and which conveys the plastics material pre-forms and subsequently the plastics material containers. In this case, the conveying device 2 inside the heating device 4 can be, for example, an endless chain which forms part of the entire length of the conveying device and on which a plurality of plastics material pre-forms are conveyed. Reference numeral 4 relates to a heating device. However, the conveying device can also have other elements, such as conveying star wheels or the like.

Abstract

The method involves operating and temporarily synchronizing a heating unit (4) and a treatment device (6). A supply of plastic containers is disrupted to the heating unit during predetermined synchronization period in synchronization with the heating unit in time after occurrence of the fault condition when a fault condition occurs in one of the heating units arranged downstream of the treatment devices by a locking device (12). The supply of the plastic containers is re-admitted to the heating unit during the synchronization period or at the start of synchronization. An independent claim is also included for a device for treating plastic containers with time reduction when synchronizing system components.

Description

technical field [0001] The invention relates to a method for processing containers of plastics material and a machine suitable for the method. Various methods are known from the prior art for processing containers of plastic material. In this case, it is also known in particular first to heat the plastics material pre-forms correspondingly in a heating device or an oven and then to shape them in this heated state in a forming device such as a stretch blow molding machine into beverage container. Background technique [0002] Stretch blow molding machines of this type usually also have a filling device attached to them for filling containers with a liquid, for example a beverage. In this case, it is known in the prior art to have buffer paths between the individual parts of the machine which can receive different numbers of plastics material pre-forms. However, the cost of this type of buffer path is relatively high. Furthermore, machines in which the individual units are...
