Description

The invention relates to a device for treatment of rope-shaped textile goods, as they are, for example, as so-called JET dyeing machine in various embodiments in the Practice is known.

Such JET machines or plants work with transport nozzle means for the tranpsort of the textile goods. Both based on the so-called aerodynamic principle JET machines, as described, for example, in Melliland textile reports 69 (1988), pages 748 to 754, in textile technology 38 (1988), pages 31-35 and International Textile Bulletin Refinement 31 (1985), 3, pages 27 to 41, a endless strand of goods in a closed container by means of a transport nozzle system, often in the form of a JET nozzle, circulated, which as a transport medium with a Gas flow is applied, which the goods strand his advancing movement issued in the specified direction of rotation. there it is e.g. known from EP 0014919, for transporting the Goods strand as a transport medium heated gas or a To use vapor stream. About the JET nozzle is outside the container preheated dye liquor pressed on the continuous strand of goods comes to act. It are also working on the aerodynamic principle working textile treatment machines, as they are e.g. in EP 0665319 A3 and 0640710 A2. This is an endless Web loop during its through one of a gaseous Transport medium flowed through JET nozzle within the treatment device taking place transport subjected to mechanical and / or thermal treatment, around the volume, the handle, the surface image or the To change the water content of the web loop targeted.

In these JET plants it is also known in one single container multiple web loops or strands to treat at the same time, for which a corresponding number Axially juxtaposed transport nozzles available are those in the container also own storage facilities assigned to each of the delineated product strands are. In these multi-storage machines, each of the transport nozzles in the area of its slit-shaped gas inlet of surrounded by a nozzle housing, which has its own gas supply line to a connected to a common fan Pipe is connected. The blower itself is in usually arranged outside the treatment tank and suction side connected to the interior.

The formation of the transport nozzles with their own nozzle housings and their connection to the transport medium source over own stubs are expensive; also is the Transport medium distribution and loading of the transport nozzles occasionally not even enough.

The object of the invention is therefore the aforementioned Device for the treatment of rope-shaped textile goods educate so that remedied these disadvantages becomes.

To solve this problem, the inventive Device on the features of claim 1.

In the new device, the transport nozzle means at least two separate, axially juxtaposed Transport nozzles for each one strand of goods. The transport nozzles are in a common Transport medium distribution device used with the transport medium circulating device is connected and one the transport medium inlet of the transport nozzles Having room with transport medium acting. The Transport medium distributor device realized thereby the so-called common rail principle. Because the transport nozzles directly into this transport medium distribution device are used, accounts own nozzle housing and stubs to the transport nozzles. At the same time in very much easier efficient way of even distribution ensures the transport medium to the individual transport nozzles.

In a preferred embodiment, the Transport medium distribution device a Transport medium distribution box, which with the pressure side the circulating device is connected and in the Transport nozzles are used. This distribution box extends expediently at least over a part the axial length of the container, being within or can be arranged outside the container. An advantage This distribution box is u.a. in that one very even distribution of the gaseous transport medium can be achieved because the transport media speeds by correspondingly large dimensioning of the cross-sectional dimensions keep the box low. If necessary, additional measures can be taken be to the uniformity of the transport medium distribution to increase the individual transport nozzles. Thus, e.g. in the distribution box Transportmediumsleitelemente be arranged, the u.a. Have baffles can, which the transport nozzles, at least partially, enclose. Such baffles provide a concentric Influence of the gaseous transport medium from the Distribution box in the annular gap-shaped transport medium inlet the transport nozzle.

Overall, the arrangement of the Nozzles directly in the transport medium distribution device an efficient and effective transport medium inflow in the transport nozzles and thus a flawless Transport of the goods strand.

When arranged in the container distribution box is that of the arranged in the distribution box transport nozzles outgoing noise emission automatically reduced. At the same time, the heat radiation from the distribution box largely suppressed to the outside, bringing the thermal Efficiency of the whole machine is increased. Finally, the distribution box located in the container brings with the transport nozzles arranged in it yet the advantage that the respective strand of goods of the memory during transport through the transport nozzle only to one opposite conventional machines reduced height raised must be, which results in a gentle transport.

Regardless of whether the distribution box within or placed outside the container can him optionally actuatable control means for the Transportmediumbeaufschlagung be associated with the transport nozzles. These Control means may in one embodiment, the transport medium supply to the distribution box controlling means and / or the arrangement can be made in such a way that the transport nozzles Wahlwiese operable control means are assigned by the Transportmediumsbeaufschlagung individual transport nozzles is controllable. Otherwise required the transport medium distribution in the distribution box, except from the possibly useful, above-mentioned guiding elements, no complicated diversions or the like, so that the transport medium supply the transport nozzles with high efficiency. Because of this high efficiency may increase the performance of the transport medium circulation device be reduced accordingly.

Further developments of the subject of the invention are Subject of dependent claims.

The invention shown in Figures 1, 2 Device is a JET piece dyeing machine with several here four - Save on the aerodynamic principle. Of the basic structure of such JET Stückfärbemaschinen is are known per se (cf., for example, EP 0945538 B1), are therefore in the Below only the essential features of the invention described. The device has one in Fig. 1 only schematically illustrated, closed container 1, acting as a substantially cylindrical pressure vessel is trained. Lead into the container 1, as shown in FIG. 2 to see, four control ports 2, each of which one Memory 3 associated with an endless strand of goods 4 and closed by a control closure 5 pressure-tight is. The memory 3 are through partitions. 6 bounded laterally in the axial direction of the container 1. The in strand 4 of them, as illustrated at 7, plaited.

In the container 1 is a by a not shown frequency controlled electric motor driven reel 8 rotatably mounted, which is accommodated in the container 1 Connect transport nozzle means, which for each memory 3 has its own Venturi transport nozzle 9, which only schematically illustrated in Fig. 2 is. Each transport nozzle 9 has one as an inlet for the gaseous transport medium, for example. Air, gas, steam or a Air-steam mixture, forming annular gap 10 on the between a nozzle cone 11 and a coaxial with it diffuser 12 is formed. The diffuser 12 goes into a curved piece 13 on, which is followed by a Abtafler 14.

In operation, the rope-shaped textile is through the respective operating opening 2 is introduced into the container 1 and thereby placed on the reel 8 and through the transport nozzle 9 performed, whereupon the strand of goods to his Ends to an endless loop of goods is connected. To the loading of the container 1 with that of the four memories 3 associated four strands 4 are the operating openings 2 closed and the transport nozzles 9 are with the gaseous transport medium is applied, whereby each endless strand of goods 4 in the clockwise direction, with reference to FIG. 2, is circulated, as illustrated by an arrow 15 is. During this orbital movement of the goods strand 4, its treatment is carried out in the container contained treatment liquor, which is circulated and in the areas of the transport nozzles 9 on the respective strand of goods 4 is abandoned. The necessary piping, Pumps and the like are not further illustrated. For this purpose, for example, on the already mentioned EP 0 945 538 B1 or EP 0 078 0722 A1.

In the container 1 is in the areas above the Memory 3 is in the axial direction substantially over the storage 3 extending transport medium distribution box 16 arranged, which is a substantially rectangular Cross-sectional shape with an approximately roof-shaped top wall 17th having, as seen in Fig. 2, the curvature of the Mantels de cylindrical container 1 is adjusted. By this design of the distribution box 16 results in a space-saving storage in the container 1. The distribution box 16 is closed on an end face at 18 and on its opposite end face 19 via a at 20 indicated screw with the pressure channel 21st a blower 22 connected to that part of a Transport medium circulating device forms.

The fan 22 is, as shown in Fig. 1, in the container 1 in the areas of its adjacent body bottom 23 arranged. It is driven by an electric motor 24, the sealed in a respect to the container interior Housing lying frontally protrudes from the container 1. The blower 22 has an over the axial length of the Memory 3 extending, to the container 1 coaxial perforated Intake manifold 25 on that it allows a vapor-air mixture sucked out of the container interior and over the Pressure channel 21 in the transport medium distribution box 16 to promote.

As can be seen in particular from FIG. 2, the Transport nozzles 9 directly into the transport distribution box 16 used, such that they are axially parallel arranged to each other, the opposite side walls Traverse 26 of the distribution box, on the one hand the nozzle cone 11 and on the other hand, the diffuser 12th above the respective distribution box side wall 16 above sealed connected to this. The transport nozzles 9 therefore lie with their transport medium inlet forming Annular columns 10 in the distribution box 16, the extent encloses all transport nozzles.

In operation, the interior of the distribution box 16 with the gaseous transport medium conveyed by the fan 22 acted upon, via the annular gap 10 in the respective transport nozzle 9 flows concentrically and thus a uniform, gentle transport of the goods strand 4 causes. As can be seen from Fig. 2, the Distribution box 16 has a relatively large cross-section has, the transport speed is in the Distribution box 16 relatively low, with the result that is a very even transport medium distribution on the four transport nozzles 9 results.

The accommodation of the transport medium distribution box 16 in the container 1 has the consequence that the distribution box 16 hardly radiate heat to the outside of the container can, so that hardly any heat loss in the distribution box 16 and the transport nozzles 9 flowing through, temporarily hot transport medium occur. It also works the distribution box 16 sound-absorbing for those of the Transport nozzles 9 outgoing noise. The walls 17, 18, 19, 26 of the distribution box 16 need in their Wall thickness only on the total pressure increase of the blower 22 and not for the maximum operating pressure in the Container 1 to be designed because of the distribution box 16th is housed in the container 1. Finally, FIG. 2 that by the arrangement of the junction box 16 with the inserted in him transport nozzles 9 in the upper region of the set up in horizontal axis operation Container 1, the transport nozzles 9 relatively close to the central axis 27 of the container 1 can zoom, with the result that the deduction height of the strand of goods 4 from the Memory 3 is reduced during transport, which is a gentle on the goods Transport results.

The embodiment according to FIGS. 3, 4 differs from that according to FIGS. 1, 2 merely by that the transport medium distribution box 16 outside the Container 1 is arranged. With the figures 1, 2 same Parts are therefore provided with the same reference numerals and not explained again. For the sake of simplicity, is in Fig. 4 omitted the representation of the product strand 4.

In the rectangular cross-section distribution box 16, the paraxial to the cylindrical container 1 directly On top of these are the four transport nozzles 9 in a corresponding manner, as shown in Fig. 2, used directly, such that you make the transport medium inlet more Annular gap 10 enclosed by the distribution box 16 is. In each of the transport nozzles 9 of the pipe bend 13 is on Diffuser outlet via a vertical pipe section 28 in the areas the respective memory 3 is returned to the container 1, while the nozzle cone 11 via a pipe 29th above the reel 8, not shown in Fig. 4 to the Container 1 is connected.

The fan 22 is outside in this embodiment of the container 1 arranged coaxially thereto. Be Pressure channel 21 is connected via a screw 20 and a corresponding pipe piece back to the front side 19 of the distribution box 16 connected.

The distribution box 16 can, if necessary, with a special heat-insulating or noise-damping Envelope or lining provided in Fig. 4 indicated by dashed lines at 30.

The transport means distribution box 16 is in the described embodiments as a substantially over the length of the container 1 extending, in cross section rectangular tube shown on at least two sides is bounded by parallel side walls 26. Basically, the distribution box 16 naturally each have appropriate cross-sectional shape, in particular also one which, when installed in the container 1 adapted to the inner contour or the components contained therein is. Especially with more memory versions The device may be useful on the distribution box 16 over its axial length additional measures to provide a uniform Transportmediumsbeaufschlagung the individual transport nozzles 9, regardless of the distance from the mouth of the blower pressure passage 21st to ensure. For this purpose, for example, air distribution elements in the form of baffles, baffles or be provided in the distribution box. Possibly It is expedient also annular around the transport nozzles 9 arranged baffles to provide for a concentric entry of the transport medium from the Distribution box 26 in the annular gap 10 of the respective Ensure transport nozzle. Another to even out the Transportmediumsbeaufschlagung the transport nozzles serving Measure could also consist in the cross section of the Distributor box 16 to change over its axial length, such that in the distribution box 16 everywhere a uniform flow velocity results.

The distribution box based on the common rail principle 16 also allows the Transportmediumsbeaufschlagung in a simple manner the transport nozzles 9 as needed to Taxes. This can be in one shown in Figures 5, 6 Embodiment by control means in the form of a Slider 31 happen that via an actuator 32nd is controlled, which from the shut-off position shown in Fig. 5, according to the arrow 33, into an ineffective one Position can be withdrawn. The slider 31 is between the connected to the pressure channel 21 of the blower 22 End wall 19 of the distribution box 16 and this arranged adjacent to the first transport nozzle 9 and can thus the transport medium inflow to the distribution box 16 overall. In this way, the Transportmediumsbeaufschlagung the four transport nozzles 9 for all transport nozzles evenly regulated.

Additionally or alternatively, the distribution box 16 associated control means but also designed be that they have an individual regulation of Transportmediumsbeaufschlagung the individual transport nozzles 9 enable. Such an embodiment is shown in the figures 7, 8 illustrates. The housed in the container 1 Transport medium distribution box 16a is basically similar as the distribution box 16 of FIG. 1, 2 constructed. However, it contains, as can be seen in particular from Fig. 8, one parallel to the bottom wall and spaced therefrom Intermediate wall 34, which is the actual distribution box space 35 limited, in the pressure channel 21 of the container in the first arranged blower 22 opens. The partition 34 extends below the transport nozzles 9, wherein the above Partition 34 and below the top wall 17 lying room in the distribution box 16a is divided by transverse walls 36, each containing a transport nozzle 9 Transportmediumsspeiseräume or chambers 37 limit. These transport media dining rooms 37 are connected to the distribution box space 35 connected through passage openings 38, the passage cross-section for the transport medium in each case by a shut-off device 39 can be influenced by an associated Adjusting device 40 are adjusted individually can.

While in the embodiment of Figures 7, 8 the individual control of the Transportmediumsbeaufschlagung the individual transport nozzles 9 by measures in the Distributor box 16a are achieved, are also embodiments possible, where directly on the transport nozzles 9 is taken for this purpose. Such Embodiment show the figures 9 and 10th

In this embodiment is on the annular gap 10 delimiting nozzle cone 11 and / or the catching nozzle forming extended part of the diffuser 12 a sliding sleeve 41 attached, which as in particular from Fig. 10 to see, in the direction of a double arrow 42 axially and is adjustable, such that they the annular gap 10 more or less. In this way, the transport medium flow individually in the respective transport nozzle 9 be adjusted, as with a view to a gentle on the goods Transportation at maximum speed required is. The possibility of closing the annular gap 10 completely, eliminates the need for a butterfly valve that otherwise required if a transport nozzle 9 is not is used. The elimination of the butterfly valve is eliminated their flow resistance, bringing the efficiency of the in turn increased whole device.

In Figures 5 to 10 are the same for the same parts Reference numeral as used in Figures 1, 2, wherein on a repeated explanation of these parts is omitted.

In the foregoing, the invention has been described with reference to a JET treatment machine explained according to the aerodynamic principle. In principle, however, it is possible the common rail concept of the transport medium distribution box 16, 16a with the also directly used transport nozzles 9 for JET treatment machines that use a liquid Transport medium, i. according to the hydraulic principle work.

In the described embodiment, the container 1 pressure-resistant. But the invention is also applicable to so-called atmospheric machines which the container is not pressure-resistant.
