Embodiment Construction
[0032] exist Figures 1 to 2b A perspective view of a first embodiment of the device for controlling the blowing medium in a stretch blower according to the invention is shown in . As can be seen, the device has a housing block 10 with a first through-opening 11 designed to accommodate a blowing nozzle 100 . In particular, the through-hole 11 is designed cylindrically and extends from the housing block 10 at figure 1 The upper side shown in extends to the lower side not shown.
[0033] Also in the housing block 10 there are control valves 20 , 30 , 40 , 50 and 60 which are connected to the first through-hole 11 and are designed to selectively switch the blower received in the through-hole 11 The air nozzle 100 is connected to a corresponding fluid interface. The fluid connection of the valves 20, 30, 40, 50 to the first through hole 11 is subsequently referred to Figures 3 to 5 The description in to clarify.
[0034] Housing block 10 has a number corresponding to the num...

The present invention relates to a device for controlling blowing mediums in a stretch blow moulding machine for producing hollow bodies of heated preforms, wherein the device comprises a housing block with a first through-bore for accommodating at least one blow nozzle. In addition, a first and a second valve are provided, wherein these valves are in fluid communication with the first through-bore and configured for selectively connecting a blow nozzle accommodated in the through-bore to a fluid connection. In order to simplify the construction of the device and to prevent leakages, the housing block furthermore comprises first and second valve channels for accommodating the first and the second valve within the housing block, wherein the first and second valve channels are in fluid communication with the first through-bore.
Description
technical field [0001] The invention relates to a device according to the preamble of independent claim 1 for controlling the blowing medium in a stretch blowing machine for producing hollow bodies made of heated preforms. Background technique [0002] Blowers are sufficiently known from the prior art. The hollow body on the blower typically consists of thermoplastic with a volume of between 0.05 and 20 liters. Typical blown parts are bottles as well as transport, packaging and storage containers. For bottles and containers up to 20 liter capacity polyethylene terephthalate (PET) is preferred today. [0003] For example, blowers designed for PET bottles are known in different variants (with and without mechanical cross bars). In this case, a tubular or bell-shaped blowing nozzle is placed, for example, directly on the mouth of the preform in a gas-tight manner or on a transport carrying the preform, in order to blow the preform with low-pressure blowing air. , high press...
