Problems solved by technology

[0004] The machines and equipment used to sterilize containers are usually of complex structure, which inevitably makes these machines not flexible enough for the containers produced
Therefore, although it is easy for container production machines such as stretch blow molding machines to be properly adjusted according to different specifications of the produced containers, it is difficult for the processing unit to be flexibly adjusted according to different container requirements
One of the disadvantages of the prior art is that different devices are required for different food containers, for example, bottles for carbonated beverages and bottles for non-carbonated beverages, with the ensuing cost and complexity significant increase in sex

Embodiment Construction

[0027]FIG. 1 shows a container production plant 1 comprising a preform sorting and feeding device 23 , a heating furnace 22 and a stretch blow molding machine 24 . The preforms are fed from a storage device (not shown) into a preform sorting device 23 and conveyed through a supply system to a heating furnace 22 where they are heated to a certain temperature. The heating furnace 22 may be an infrared heating furnace or a microwave oven. After exiting the furnace 22 the heated preforms are transferred via the inlet star wheel 25 to the blowing wheel 27 . The blow molding wheel is provided with a plurality of blow molds (not shown in the figure), and the preform is blown by compressed air in these blow molds. The blow-molded bottles are then picked up by the outlet starwheel 26 and transferred to the transfer starwheel 10a, which serves as the outlet starwheel 26 and the first transfer starwheel in the container processing station 2 10 transmission connection devices between. ...

Abstract

The invention relates to a device and a method for the production of containers, such as bottles, wherein different types of bottles are produced. Depending on the type of bottle to be produced, alternative treatment methods are used. If bottles for carbonated drinks are to be produced, a cooling treatment is used. If bottles for non-carbonated drinks are to be produced, a sterilization treatmentis performed.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 16 . Background technique [0002] The machines used to produce plastic containers are usually machines used in the pharmaceutical and food sectors. These machines and methods are mainly used for the production and pretreatment of containers, such as bottles, cans, bags or vials. Containers made of plastic, especially polyester, are usually produced, processed, filled and closed. [0003] Such machines for producing, handling and filling containers are well known to those skilled in the art. For example, WO2006003304A1 discloses a machine for producing and filling polyester bottles, wherein the containers are treated between production and filling by a cooling operation at their bottom. EP1572540B1 discloses a device and method for sterilizing containers, wherein the sterilizing operation depends on specific environmental conditions...
