example 1

[0049] The mixed fluid is conveyed by means of gas pressure through purified nitrogen into the storage container 5 of the filling device, which substantially corresponds to figure 2 Filling device shown in . The nitrogen used for delivery had previously been filtered through a gas filter. according to figure 1 , the storage vessel 5 was connected to a pump 6 (Levitronix), a membrane degassing unit 9 and two PTFE filters 8, 18 (Entegris) with pore sizes of 0.1 μm and 0.05 μm, respectively. The purification process according to the invention is carried out in such a way that the fluid is initially circulated in the optical particle counter through the pump 6, the filter device 7 and the pollution measurement device 15, the measured key pollution indicators are respectively compared with the desired or pre-defined target parameters for comparison. The fluid (respectively ink or just solvent) returns to the storage container 5 after passing through the contamination measuring ...

example 2

[0058] The filling process begins as soon as the corresponding fluid according to example 1 is present in the purge circuit in a purge manner. Here, the transport container 12 is integrated into the purification circuit 1 . The fluid quantity taken from the transport container 12 thus flows back into the cleaning circuit via the valve 16 and the connection 14 . A throughflow and contamination measuring device 15 is located in the return line to the storage container 5 , via which the overall dissolved gas content, in particular the oxygen content, can be detected. The shipping container 12 is flushed with the already cleaned fluid until the target parameters are achieved in the return flow from the shipping container 12 . As an example, a number of 150 ml bottles (Merck decontaminated glass bottles, decontaminated) were used as shipping containers 12 and filled with "Reserver Cleaning Solvent" fluid. Here, the bottles are incorporated into the purification circuit 1 until th...

example 3

[0062] The filling process begins as soon as the desired fluid according to example 1 is present in the purge circuit in a purge manner. In this example, the filling of the transport container 12 configured as an ink cartridge 30 is described. To this end, the filling device includes the additional function of flushing the transport container 12 , ie flushing the transport container 12 by alternately filling and emptying it with already purified fluid. This alternating operation is repeated a number of times until the desired pollution concentration is achieved and is below a predefined threshold for key pollution indicators. To this end, during emptying of the transport container 12, the container return line 13 is connected to the fluid line portion 3 and subsequently to the contamination measuring device 15 in order to establish key contamination indicators. After passing through the contamination measuring device 15 the fluid returns to the storage container 5 and is agai...

Abstract

In the method of filling the transport container (12) with fluid, the fluid is repeatedly conveyed through the purification device (7) in the purification circuit (1) and a sample of the fluid in the purification circuit (1) is determined using a contamination measuring device (15) A pollution indicator of the quantity, wherein only when the pollution indicator falls below a first threshold value, the filling process of filling the transport container (12) with fluid is ended. A sample volume of fluid provided for determining a pollution indicator can be drawn from the purification circuit (1), fed to a pollution measurement device (15) and fed back into the purification circuit (1) after the pollution indicator has been determined. In a container decontamination step, the volume of container fluid previously introduced into the transport container (12) from the decontamination circuit (1) can be removed from the transport container (12) again and fed back into the decontamination circuit (1). A contamination indicator of the volume of fluid sample removed from the transport container (12) can be determined using the contamination measurement device (15) and filling of the transport container (12) with fluid is terminated only when the contamination indicator falls below a third threshold process.

Description

technical field [0001] The invention relates to a method of filling a transport container with a fluid, wherein the fluid is passed through a purification device before filling the transport container. [0002] technical background [0003] In recent years, various organic semiconductor materials have been developed which are suitable, for example, for the production of organic semiconductor components, in particular for the production of organic light-emitting diodes and corresponding displays. Various printing techniques are especially suitable for the processing of organic semiconducting materials, by means of which organic semiconducting materials, already dissolved in suitable solvents, can be applied to predefined surfaces. In this way, for example, large-area displays assembled from a large number of organic light-emitting diodes (OLEDs) that can be actuated independently of each other can be printed using inkjet printing devices known in practice . [0004] Currentl...
