Description

  The present invention relates to a string-like textile product comprising a closed container and a venturi conveyance nozzle system to which a conveyance medium flow is supplied to drive an endless string product circulating in the container in a predetermined circulation direction. The present invention relates to a wet processing machine.

  In fact, such wet processing machines, which are known in some embodiments as jet dyeing equipment, etc., are based on hydrodynamic principles or depending on whether the transport medium stream is liquid or gaseous. Operates on aerodynamic principles. When the endless string product sent out by the transfer nozzle system goes out of the transfer nozzle system, the endless string product is folded by the cutting device and then accumulated in the accumulating unit. Supplied to. A take-up means, usually having a winder for each transfer nozzle of the transfer nozzle system, is attached to the transfer nozzle system in order to pull the string from the accumulator and insert it into the string product inlet of the transfer nozzle system. . The winder driven by the electric motor is positioned in the path of the string product in front of the string product inlet of the transport nozzle attached to each, and the string product pulled out from the accumulation unit is the string product inlet of the transport nozzle. Before entering, it is turned at least 90 ° in a substantially vertical direction. In the substantially vertical area of the string product travel path from the winder to the accumulator, a part of the processing dye liquid carried together by the string product dripped, which means that the string product is wound by its own weight. It is promoted by being placed on the surface of the machine and thereby being more or less compressed.

  In order to apply the processing dye liquid as evenly as possible to the circulating string product, the processing dye liquid is circulated by the dye liquid circulation pump and is applied to the string product in cooperation with the transport medium flow. In this type of wet processing machine known from US Pat. No. 6,057,017, a treatment agent in the form of a spray is added to a gas stream that serves as a transport medium stream for a circulating string product. In another post-dyeing machine as described in US Pat. No. 6,053,099 operating on the principle of aerodynamics, the treatment agent is introduced into the nozzle housing of the conveying nozzle, and the particles of the treating agent are brought into the annular shape of the nozzle by a gaseous conveying medium flow It is evenly applied to the string product that is passing through the gap, and the processing agent is kneaded into the string product when it further passes through the concentrated section of the transport nozzle.

  In practice, it has been found that there is a limited amount of liquid processing dye liquor that can be injected into a gaseous carrier stream on a jet wet processing machine operating on the principle of aerodynamics. . That is, the droplets of the processing dye brought into the transport medium stream are accelerated in the direction of travel of the string product, which requires a considerable amount of energy of the transport medium stream, and this energy is absorbed by the blower that sends the transport medium stream. Must be applied. However, particularly when the string product is washed, it is desirable to obtain a high dye solution flow rate by the transport nozzle in order to shorten the washing time and realize an excellent washing action.

European Patent Application No. 00078022 European Patent Application Publication No. 09455381

  The object of the present invention is therefore to open the way for making it possible to improve the application of processing dye liquor to string products in a simple manner.

  In order to solve this problem, the wet processing machine according to the invention has the features of claim 1.

  This new wet processing machine comprises means for applying a processing dye solution to the string product in the area of the string product travel path between the area of the winding means and the nozzle annular gap of the conveying nozzle system. The means acts on the lace product in addition to or as an alternative to the means in the area of the transport nozzle system to apply the process dye liquid to the lace product, so that already in the area of the nozzle annular gap of the transport nozzle system Then, the processing dye is applied to the string product. The application of the processing dye liquid to the string product is performed between the area of the winding means and the nozzle annular gap, so that the string product is particularly effective before being processed with the processing dye liquid in the conveying nozzle system. Wetting of the string product is realized. This is because the string product traveling path between the winding means and the conveying nozzle system, which usually extends slightly inclined with respect to the horizontal direction or the horizontal line, is relatively short, so that the string product conveys most of the applied processing dye liquid. This is because it is brought into the nozzle system. Accordingly, the proportion of processing dye applied to the string product in the area of the transport nozzle system itself can be reduced.

  The means for applying the processing dye solution to the string product is suitable for the purpose if the processing dye solution coming out of the application means is arranged so as to have at least one moving component in the traveling direction of the string product. Thereby, since the process dye liquid to be applied has already been accelerated in the direction of the string product, the energy cost required to accelerate the droplets in the direction of the string product is reduced. This results in a reduction in the burden of circulating the gaseous conveying means and a faster string product circulation. In addition, the product in transit is treated with care, which is due to the fact that the droplets of the processing dye do not impinge on the surface of the string product at right angles to the direction of string product travel.

  In an actual embodiment, the treatment dye application means may be provided with spray means having a spray nozzle in the area of the winding means. This spray nozzle has a communication shaft that forms an angle smaller than 90 ° with the string product traveling direction in the region of the nozzle communication portion.

  The winding means has at least one winding machine that can rotate about the rotation axis, and the processing dye application means communicates, for example, in the area above the winding machine, so that When the processing dye liquor flowing out flows downward and hits the string product passing through the front, a simple design can be obtained. Alternatively and / or additionally, the processing dye liquor in the region located between the rotary shaft of the winder and the nozzle taper of the conveying nozzle system, if this is possible given the design requirements Application means may communicate.

  The novel wet processing machine may additionally or alternatively be provided with means for injecting the processing dye liquor into the passage passage of the nozzle taper that communicates to surround the passage wall separating the passage passage. . Via this injection means, the processing dye liquor, that is, the processing agent is applied to the string product passing through the transport nozzle in a state separated from the transport medium stream. Again, the action of the processing dye liquor on the string product is independent of the velocity of the transport medium stream flowing into the annular gap that causes the product to be delivered. Since the injection means are arranged in the region of the nozzle taper, the string product has already been pretreated with the processing dye solution coming out of the injection means when the carrier medium acts in the annular gap. Since the injection means is arranged in a state of being distributed so as to surround the passage passage wall, when the string product passes through the passage passage of the nozzle taper portion, the treatment dye solution disposed concentrically around the nozzle opening portion is arranged. Go through the curtain. Thereby, the processing dye liquor acts very gently on the product.

  As already mentioned, in one advantageous embodiment, the infusion means has a moving component in the direction of product travel, with respect to the longitudinal central axis of the passage passage. To communicate. For this purpose, the injection means are preferably arranged such that the apex communicates with the longitudinal central axis at an angle in which the apex faces the product travel direction. By this measure, the above-mentioned treated dye curtain has a component oriented in the product traveling direction, which can be sized to approximately have the speed of the string product passing therethrough. As a result, the processing dye introduced into the passage through the injection means need not be accelerated for the first time by the passing string product carrying the processing dye together. Such an acceleration method leads to a braking action on the string product.

  In one advantageous embodiment, the injection means have injection passages communicating with the passages in a distributed manner surrounding the passage walls, the communication parts of these injection passages extending over the circumference of the passage passages. Particularly evenly distributed. Alternatively and / or additionally, however, the injection means may have at least one annular gap that extends through and surrounds the wall of the passageway, which annular gap surrounds the passing string product. Then, apply the processing dye solution evenly to the string product. In any case, however, as already mentioned, the action on the string product by the treatment dye liquor is very gentle. Necessary kneading or rubbing of the processing dye liquid into the product is performed by the conveying medium flow when the string product continues to pass through the concentrated area of the conveying nozzle extending from the annular gap in the product traveling direction. By injecting the processing dye liquid at the nozzle taper portion, there is no need to change the direction of the processing dye liquid. Since the liquid particles are not scattered or separated, which is unavoidable when the processing dye liquid is added to the transport medium stream, the processing dye liquid reaches the passing product stream directly and 100%.

  It is possible to enclose the transfer nozzle in the usual way with a unique nozzle housing in the region of the annular gap connected to the source of the transfer medium via corresponding piping. In particular, in the case of a so-called multiple storage machine that is attached to a single container so that a plurality of transfer nozzles are arranged side by side, all the transfer nozzles of the nozzle system are supplied with a gaseous transfer medium in the annular gap. It is possible to employ a configuration that is arranged so as to be located in a common transport medium distribution chamber. This distribution chamber is suitable for the purpose of being configured in a long-sized conveyance medium distribution box connected to a conveyance medium source and into which a conveyance nozzle is directly inserted.

  Developments of the invention are the subject of the dependent claims. In the drawing, an embodiment of the object of the invention is shown.

  The high-temperature (HT) post-dyeing machine schematically shown in FIG. 1 has a pressure-resistant cylindrical container 1, and an operation opening 3 that can be closed by a lid 2 leads to the inside thereof. The string product 4 can be put in through the opening. The string product 4 is introduced into the venturi transport nozzle 6 via a winder 5 driven externally, and a cutting device 7 follows the venturi transport nozzle. The cutting device 7 temporarily stores the cord product 4 coming out of the transport nozzle 6 in the storage unit 8 in a folded state, from which the endless cord product is drawn out again by the winder 5. At this time, as can be seen from FIG. 1, the string product 4 follows the string product traveling path in a substantially vertical direction between the storage unit 8 and the winder 5. The winder 5 and the transport nozzle 6 are stored in a housing part 9 that is liquid-tightly coupled to the container 1. The string product 4 is inserted into the operation opening 3 and then tied to an endless product loop at its end.

  The container 1 includes a dye liquor strainer 15, and a dye liquor discharge unit 14 connected to the suction pipe 16 of the dye liquor circulation pump 17 is disposed on the lower side. The pressure pipe 18 of the dye liquor circulation pump is heated. An exchanger 19 is included and communicates with the transfer nozzle 6 via a control valve 20 and a pipe 21. The dye liquor circulation pump 17 allows the processing dye liquor sucked from the container 1 to be circulated through the transport nozzle 6 and the container 1. The circulation path is shown in black in FIG. In parallel with the heat exchanger 19 and the dye circulation pump 17, a bypass pipe 22 including a stop valve 23 and connecting the dye discharge part 14 to the pressure pipe 21 passes.

  Finally, a preparation container containing a chemical processing agent in an aqueous solution, emulsion, or dispersion that can be sent to the suction pipe 16 of the dye circulation pump 17 via the processing agent pump 25 and the communication pipe 26. 24 is further provided. As can be seen from FIG. 2, the post-dyeing machine described above is configured as a multiple accumulation machine including four accumulation units 8 which are positioned side by side in the axial direction of the cylindrical container 1. Yes. A transport nozzle 6 is attached to each storage unit 8. These four transport nozzles 6 form a transport nozzle system. In this nozzle system, a winder 5 to be driven is attached to each conveying nozzle 6 in a manner apparent from FIG. 1, and the drive devices for these winders are not shown in detail. The winder 5 forms the winding means together with the drive device and the housing part 9.

  Post-dyeing machines which operate on the aerodynamic principle described above are known per se.

  According to the invention, additional means are provided in this post-dyeing machine in order to apply the treatment dye liquor to the string product 4 in the area of the winding means. For this purpose, it is located in front of each conveying nozzle 6 as viewed in the direction of travel of the string product, and is arranged on the connecting pipe 30 of the housing 9 in the winder 5 that can rotate around the rotating shaft 28 of the housing 9. A treatment dye nozzle 29 (FIG. 3) is attached. The processing dye nozzle 29 configured as a spray nozzle or an injection nozzle in some cases is connected to the processing dye pressure pipe 21 via a pipe 31 (FIG. 1) and a control valve 32. As can be seen from FIG. 2, in this example, the pipes 31 leading to the four transfer nozzles 6 are respectively connected in parallel to the collective pipes 33 connected to the pressure pipes 21.

  As shown in FIG. 3, the processing dye nozzle 29 is bent from the vertical direction to a direction approximating the string product traveling direction 10 in the area of the communication portion, whereby the nozzle communication shaft 34 conveys the string product. An acute angle is formed between the direction 10 and the apex when viewed from the product traveling direction. Thereby, it is realized that the processing dye liquid coming out of the nozzle 29 has a motion component in the traveling direction 10 of the string product 4.

  As shown in FIG. 3, the transport nozzle 6 has a nozzle taper portion 35 having a coaxial passage 36 for the string product 4, and then annularly with the nozzle taper portion 35 when viewed in the string product traveling direction. A diffuser 37 is formed which forms a gap 38. The annular gap 38 is disposed in a tubular nozzle housing 39 that surrounds the annular gap 38, and the processing dye pressure pipe 21 and the blower pressure pipe 13 (not shown in FIG. 3) communicate with the nozzle housing. .

  The processing dye solution pressure pipe 21 communicates with the nozzle housing 39 through a communication portion not shown in detail in FIG. 3, and this communication portion is also oriented in the circulation direction 10 of the string product 4. The droplets of the injected processing dye liquid are brought into the annular gap 38 from the communication portion by the transport medium flow.

  As an alternative or addition to the injection pipe or pressure pipe 21 communicating with the nozzle housing 39, as shown in FIG. 3, an injection passage 40 communicating with the passage passage in a state of being evenly distributed so as to surround the passage passage 36 is provided with a nozzle taper. A configuration as arranged in the portion 35 may be adopted. As can be seen from FIG. 3, these injection passages 40 are arranged such that their respective central axes are inclined with respect to the product traveling direction 10. It has a motion component in the string traveling direction 10. It can be seen from the drawing that each axis of the injection passage 40 (only one of which is shown) forms an angle of less than 90 ° with the axis of the passage passage 36.

  The injection passage 40 is branched from an annular passage 410 attached to the nozzle taper portion 35 connected to the pressure pipe 21 of the dye circulation pump 17 via the pipe 21a.

  In operation, a special processing agent such as a colorant is optionally added from the regulator container 24 and brought to the required processing temperature in the heat exchanger, and the processing dye liquor circulated in the circulation path shown in black in FIG. Is injected from the dye circulation pump 17 into the nozzle housing 39 of each transfer nozzle through the pressure pipe 21 and is applied to the passing string product 4 together with the transfer medium flow. At the same time, the processing dye solution is applied to the string product 4 through the pipe 21 and the nozzle 29 before entering the nozzle taper portion 35 in the area of each winder 5. The distribution of the processing dye liquid between the nozzle housing 39 and the processing dye nozzle 29 can be adjusted by both control valves 20 and 32 (FIG. 1). As already mentioned, the treatment dyeing liquid can also be applied to the string product 4 via the pipe 21a and the injection passage 40 of FIG.

  In the embodiment described above, the processing dye nozzle 29 communicates above the winder 5, whereas the communicating portion of the process dye nozzle 29 is connected to the rotary shaft 28 and the nozzle taper 35 of the winder 5. The structure which is located in the area | region between the string product entrance to may be employ | adopted. This is possible by the piping 31a including the control valve 32a schematically shown by the broken line in FIG. The treatment dyeing liquid is applied to the string product in a state where the string product is dispersed in a plane in the area between the rotary shaft 28 and the nozzle taper part 35 before entering the nozzle taper part 35 or at a plurality of sites. Is also possible.

  FIGS. 4 to 6 show another example of a wet processing machine according to the present invention, a high temperature (HT) post-dyeing machine based on aerodynamic principles, of which FIG. Only the container 1 configured as a pressure tank is basically shown. This machine is a so-called multiple storage machine and also includes four venturi transfer nozzles 6 arranged in the container 1 so as to be positioned side by side in the axial direction. At this time, the winder 5 attached to each conveyance nozzle is arranged so that a substantially horizontal traveling path of the string product 4 is generated between the winder 5 and the conveyance nozzle 6.

  The same parts as in FIGS. 1 to 3 are given the same reference numerals and will not be described again. The drawings do not show mechanical parts that are not important to the present invention. For details, see, for example, European Patent Application No. 0945538A1.

  The string products 4 are driven by the respective transport nozzles 9 by supplying a gaseous transport medium, usually air, steam, or a mixture of air and steam, to the transport nozzles. For this purpose, the container 1 has a pressure passage 13 in the region of the container end face, which is driven by the electric motor 11a and communicates with the transport medium distribution box 41 extending substantially over the axial length of the four accumulation sections 3. 11 is arranged. On the suction side, the blower 11 is connected to a suction pipe 42 coaxial with the cylindrical container 1 that extends over the axial length of the container 1 and has a corresponding perforation on the wall.

  The transport medium distribution box 41 is closed by an end face 150, and is connected to the pressure passage 13 of the blower 11 at the end face facing this. The carrier medium distribution box has a substantially rectangular shape (see FIG. 2), and the upper covering wall 43 is formed in a roof shape so as to match the curvature of the outer surface of the container 1.

  In the transport medium distribution box 41, four transport nozzles 6 are inserted side by side in parallel with each other in an especially clear manner from FIGS. Each transport nozzle 6 has a nozzle taper portion 35 that delimits the coaxial annular gap together with a portion that extends toward the collection nozzle 37 a of the coaxial diffuser 37, and the transport medium is evenly distributed through the annular gap 38. It flows into the diffuser 37 while being distributed. The nozzle taper 35 includes a coaxial passage 36 for the lace product 4, which is composed of a cylindrical portion 45 and a coaxial portion 46 that expands into a funnel that forms the lace product inlet. This coaxial part is followed by a cylindrical part 45.

  As can be seen from FIG. 5, the transport nozzle 6 has a transport medium distribution box 41 with a nozzle long axis oriented in the horizontal direction so that the nozzle taper portion 35 and the diffuser 37 pass through the box side walls 46 facing each other. Has been inserted.

  During operation, the transport medium is supplied by the blower 11 to the space surrounded by the transport medium distribution box 41 in which the annular gap 38 of the transport nozzle 6 is located. As a result, the four transport nozzles 6 are all connected to their respective strings. Product 4 is sent out evenly. The transport medium distribution box 41 in which the transport nozzle 6 is inserted operates on the so-called common rail principle and makes it possible to guarantee a very uniform transport medium supply to all the transport nozzles.

  As can be seen in particular from FIG. 6, the nozzle taper 35 of each transport nozzle 6 is provided with means for injecting the processing dye liquid into the passage passage 36, as shown by the arrows 240. The wall portion of the passage passage 36 is communicated in a state of being evenly distributed while surrounding the wall portion in the circumferential direction. These injection means have an injection passage 40 which is formed in the nozzle taper portion 35 and communicates with a funnel-shaped area of the passage passage 36. As described above, the communication portion of the injection passage 40 is evenly distributed in the circumferential direction over the passage passage wall. As shown in FIG. 6, the injection passage is inclined with respect to the nozzle longitudinal central axis so that the axis is at an angle with the longitudinal central axis 47 and the apex is at an angle toward the string product traveling direction 10. Is arranged in. The injection passage is connected to the inner space of the annular passage 410 that is attached to and surrounds the nozzle taper portion 35 on the side facing the communication portion. This annular passage is connected to the pipe 21a of FIG. 3 not shown in detail. It is connected.

  The processing dye liquid that has entered the passage passage of the nozzle taper portion 35 from the injection passage 40 comes into close contact with the string product 4 that is passing when it exits the injection passage 40. Since the injection passage 40 is arranged so as to be inclined in the product traveling direction with respect to the nozzle long axis, the processing dye solution coming out of the injection passage also moves in the product traveling direction to promote the conveyance of the string product in this case as well. Has ingredients. The supply of the processing dye liquid to the annular passage 410 is a pressure selected so that the speed of the component of the processing dye liquid entering the passage passage 36 in the product traveling direction 10 is approximately equal to the traveling speed of the string product 4. Performed under However, depending on the method conditions, the speed of the motion component may be higher or lower.

  Alternatively, the injection nozzle 40 may be replaced by an annular gap connected to and surrounding the annular passage 410. Embodiments are also conceivable in which a plurality of rows of injection passages 40 located side by side in the axial direction of the passage passages 36 and / or a plurality of annular gaps arranged in the same way are provided.

  It should be pointed out that in principle it is also possible to arrange the injection channel or the annular gap in the cylindrical section 45 of the passage channel 36.

  Even in this embodiment, as in the case of FIG. 1, another means for applying the processing dye solution to the string product that communicates with the area of the string product traveling path between the winder 5 and the nozzle taper 35 is provided. Can be provided. In this case, the winder 5 is disposed directly in the region of the operation opening 2 of the container 1, and the state is shown in FIG.

  Finally, it should be noted that the present invention is not limited to application in wet processing machines based on aerodynamic principles. The present invention can also be applied to a jet-type wet processing machine operating with a liquid carrier medium.
