The invention relates to a method and apparatus for uniform application of the manufacturing environment on the cable material in the dyeing machine.

Jet dyeing machines have a closed container in the transport nozzles, supported by an external mechanical actuator; an endless strip of textile material placed in the container and rotates in a certain direction. To move the cable material transport nozzle produces a jet transport medium consisting of the dyeing liquid, or use the mechanisms of how this model system consisting of a gas, air, steam or a steam-air mixture.

An example of such system is shown in U.S. patent 4483032 and, respectively, DE 3142200.

In this type of dyeing machines in the field of transport nozzle liquid dye is applied on a moving endless rope material. Excess liquid dye collects in the container and returns to the process using a recirculating pump dye bath. An example of such a system are described in the patent DE 19813593 A1. Thus, the steam treatment is carried out rope material before wet processing.

In all the above-mentioned dyeing machines processing agents used for the coating material (chemicals and/or dyes), original Bay is carried out in the preparatory container, outside dyeing machine, in the preparatory container they are mixed, if applicable, and, if required, heated to a certain temperature, and then entered in the duty cycle of dye bath using an additional pump. Typically, processing agents, therefore, are dosed, which means that at certain times during the operation of wet processing a certain number of the manufacturing environment contained in the preparatory container, sprayed by an inkjet method on the cable material, preferably about transport jets. From the document DE 19813477 A1 it is also known that when the preparatory operation of the liquid processing medium is circulated in the container without affecting the cable material.

If we consider the processing operation more carefully, we can see that the concentration of the processing environment is increasing from one turn of the cable material to another, but at the same time, the concentration of the processing environment at the beginning of the cable material is lower than at the end of the cable material. If the manufacturing environment, for example, dosed five turns of the cable material, on the fifth turnover of the cable material at the end of this material may be a higher concentration of the manufacturing environment than it needs to be provided for the I uniform concentration. Uniform concentration is achieved after a few more turns of the rope material.

When handling the cable material manufacturing environment is essential that the entire length of the cable material is necessary to ensure uniform distribution of the processing environment, i.e. the distribution of the dye. Only in this case it will be consistent even coloring material.

Therefore, the objective of the invention is to provide a method and device which will provide a completely uniform distribution of the processing environment of cable material, which rotates in the car wet processing.

To solve this problem created a processing method according to the invention in accordance with paragraph 1 of the claims.

In the new method, endless rope material rotates in a closed container through the Venturi nozzle, which moves gaseous transport medium. The rotational motion of the material is provided by the jet of gaseous transport medium, not the dye bath. First, the manufacturing environment is stored in the chamber, separated from the cable material without contact with the cable material, for example, such a camera may be under the vault of the cable material, which is located in the sump of the manufacturing environment in the container. All n the necessary chemicals, dyes, etc. are in this tank into the container. Liquid manufacturing environment is in the chamber, and the environment or dyeing liquid can be, for example, heated to a certain temperature and then mixed in an appropriate agent release cycle manufacturing environment, without entering into contact with the material. The camera can also be designed for its location outside the container, for example, in the form of a separate container.

In the next stage of the operation of an existing manufacturing environment in the form of fresh dyeing liquid is applied in the regulated time the number on the moving cable material, providing, thus, largely uniform distribution of the processing environment of cable material.

The application of the manufacturing environment on the cable material can be performed in one or several turns of the cable material. Using the appropriate intellectual control flow of the processing environment through the transport nozzle in the direction of movement of the material prior to transport nozzle and/or nozzle, within a few turns of the cable material (approximately 2-3 turnover cable material) or even during a single turnover of the cable material can be achieved uniform deposition manufacturing environment along the entire length of the cable material.

D is I this adjustable time operation of applying the manufacturing environment during their respective turns of the rope material is pre-calculated mathematical model, which controls the application of the manufacturing environment on the cable material. Preliminary calculation procedure of applying the manufacturing environment on the cable material in this mathematical model is based on a specific data item, structure and operation of the cable material and/or nozzles to deliver transport environment. These data can be entered by the operator into the computer with mathematical models, or it can be automatically recorded in a machine with appropriate sensors. A computer program calculates on the basis of relevant parameters of the mathematical model, a timed uniform application of the manufacturing environment on a moving rope material, providing a perfect distribution of the manufacturing environment along the length of the cable material.

The advantage of this method is that it provides rapid and uniform distribution of the processing environment around the rope, creating the necessary prerequisites for painting. In addition to saving the time required for such processing, coating manufacturing environment requires a much smaller number of cycles compared with the above-described known method.

Further advantages of the invention are the object of claims and can be better understood smokebush description of the method of the present invention with reference to the attached drawings, on which:

5 is a diagram, as shown in figure 4, illustrating the colorful coating on the cable material, using the already known method.

High temperature dyeing machine, piece dyeing, schematically shown in Fig.1-3, has a solid cylindrical container 1, which has a hole 3 provided for technical purposes, which may be closed by a cover 2, and through this hole can be entered rope-material 4. Rope-material 4 is injected into the Venturi nozzle 6 with a roller 5 having independent drive. Nozzles of the Venturi is connected with a device for coating 7. Device for coating 7 puts rope-material 4 into the chamber 8, from which the rope is again drawn through the roller 5. The roller 5 and the transport nozzle 6 is located in the housing 9, which is sealed to the container 1. The ends of the rope-material 4 are connected to each other to create a closed loop, after the rope is inserted through the hole 3 to be processed.

A jet of gas which acts as a transport environment that impinges on the nozzle 6, and this jet of gas gives the cable material 4 rotational movement in the direction shown by the arrow 10. In the case discussed here, the transport medium is either a gas or a mixture of steam and air. She sucked in by the vacuum pump 11 and the suction pipe 12 of the container 1 and is fed into the nozzle 6 through a pressure pipe high pressure.

At the bottom of the container 1 has a reservoir or sump, and it has a sieve for 15 baths. Pallet tubs 14 connected to the suction inlet 16 of the main pump 17, the outlet of which contains a heat exchanger 19, and the exhaust pipe connected to the nozzle 6 through the reverse (control) valve 20. The main pump 17 circulates the bath, sucked away from the container 1 and is filed through his pallet in the nozzle 6 and the container 1. Parallel to the heat exchanger 19 and the main pump 17 passes air pipe 22, which has a shut-klapa is 23 and connects the pallet 14 from the outlet 21, which again is connected with the heat exchanger.

Finally, there is another metering device 24, which contains a manufacturing environment - chemicals in the form of a solution, emulsion or dispersion (chemicals, dye and so on)that can be fed into the suction pipe 16 of the main pump 17 through the dosing pump 25 to the manufacturing environment and through the connecting pipe 26.

The dyeing apparatus of piece dyeing, described above, works on aerodynamic principle, which is itself well known. To ensure uniform coating of the manufacturing environment on a rope-material 4, which is in rotational motion, use the following method according to the invention.

Liquid manufacturing environment, which contains all the additives required for wet processing (like chemicals, dyes, etc.), served in a tank-hopper 24. The container 1 is empty. The cable material can be either fixed or live in the rotational motion under the influence of the flow of the transport medium flowing by the fan 11. In the first processing stage shown in figure 1, the manufacturing environment located in the tank dispenser 24, is fed to the tank or sump 14 of the container 1 with all the necessary additives by means of a dosing pump 25, an employee for filing a manufacturing environment. The main pump 17 nah what is in the off position, and shut-off valve is open. It is obvious that the flow of the processing environment in the tank/sump 14 is carried out without any contact with the rope-material 4, since the manufacturing environment is stored in the tank (pan) 14 (shaded in figure 1) and is located below the storage chambers 8; therefore, it does not come in contact with the rope-material 4.

After processing environment was filed in the tank/sump 14, it circulates through the circulation path shown with a darker color in figure 2. It circulates through the circulation pump 17 and, thus, completely miscible. At the same time it is heated to the desired temperature in the heat exchanger 19. As can be seen from the drawing, the circulation through the loop pipe 22 and the tank/sump 14 by pump circulating the bath 17 and the heat exchanger 19. Valves switch 23 and 28 are open. Dosing pump 25 that is designed to pump manufacturing environment, is in the off position and locked on the high pressure side stop valve 27. Manufacturing environment, which now circulates along a fixed path until it comes in contact with the rope-material 4.

At the third stage of processing shutoff valve 23 is now closed, the main pump 15 sucks the manufacturing environment, which by this time is fully mixed in the tank/sump 4, and pumps it through the outlet 21 into the nozzle 14, where it is put on the cable material. The excess coating material flows into the tank/sump 14 and again climbs the main pump 15.

The process of coating the cable material 4 manufacturing environment is controlled by computer 29, which determines the parameters of the medium flowing through the circulation pump 15, and/or check valve 20 in the exhaust pipe 21, and/or the fan 11 and the throttle valve 30 in the exhaust pipe 13. The computer 29 is programmed according to the mathematical model, which is calculated based on parameters or data specifically on this material and/or calculated to determine the options and/or other factors that affect the processing of rope-material 4 or the nozzle 6. Among other data or parameters relating to the material, it is possible to mention the weight of the substrate and finish rope-material 4. From these data it calculates the maximum amount of liquid in litres that can be absorbed cable material per meter square. The amount of fluid that is actually absorbed, is defined as the ratio of the weight of the cable material to the so-called magnitude of the absorption And which is regarded as characteristic data. Among the other parameters are considered such as the size of the nozzle length of the nozzle, the size of the annular gap is so, which are data defined by the project. The speed of the rotational movement of the rope-material 4, the temperature of the processing environment and the distance between him and the manufacturing environment, humidity cable material at the time of entrance to the nozzle 6, etc. is all you need to know to determine the processing parameters. Volume manufacturing environment on a moving rope-material 4 in the nozzle per unit of time is regulated by the computer 29 so that, first of all, to achieve uniform distribution of the material, i.e. the desired layer in the manufacturing environment on a rope-material 4. Depending on the computer program and the data applied to the input by the user, an optimum distribution of the coating on the rope-material 4. The coating material, i.e. the manufacturing environment, can be applied during one or more cycles of rotational motion of the cable material.

Figure 4 shows an example of the method of the invention or view a clear picture of the way that is done in this invention. The manufacturing environment (i.e., the dye is applied to the rope material in a quantity, measured in grams per liter, shown here, the length of the cable material. The example used in figure 4, based on the road surface during one cycle of the rotational motion of the cable material for fresh the first material, taken from the tank/sump 14. However, note that in the first cycle of the rotational motion of the cable material difference in concentration between the beginning of the war and its end is relatively large. However, the difference in concentration between the beginning and the end of the cycle in the second cycle is much smaller. Therefore, a very good coating uniformity is achieved over the entire length of the rope already in this cycle. In the third cycle of the rotational motion of the cable material (shown by the dotted line) is almost uniform distribution of the coating material is achieved along the entire length of the rope. In the second and third cycles of rotational motion of the cable material manufacturing environment, marked on the cable material 4, contains material which is a mixture of material that was collected during the previous loop of the rope 4 and collected in the tank/sump 14 and, in turn, mixed with material that was still in the tank/sump 14.

Experiments have shown that basically you can make a program of computer 29 so that it will adjust the dosage of the coating on the average per unit of time so that the desired uniform distribution of the processing environment can be achieved even during one cycle of rotation of the cable material. However, in the scheme shown in figure 4, it is achieved that is are in the third cycle, i.e. in the third period of the rotational motion.

To compare the new method with the known technology, figure 5 shows a graph, which corresponds to figure 4. This graph represents the floor of the manufacturing environment (i.e. dye) cable material 4, which is in motion, when used this way. In this way the medium (material)located in the tank dispenser 24, dosed in the suction pipe 16 of the main pump 17 through the metering orifice 30. This is done so that the number of working material in the tank dispenser 24, served in circulation injector tube dyeing apparatus within a predetermined time. However, from figure 5 we can see that the concentration of the manufacturing environment on a rope-material 4 is increased from one loop of the rope to the next, and the concentration of the coating at the beginning of the rope is also less than the concentration of the coating at the end of the rope. In the fifth cycle of the rotational motion of the cable material at the end of the rope creates a higher level of concentration in the manufacturing environment, which exceeds the average equilibrium concentration that must be achieved. Only after seven cycles of rotational motion of the cable material in this example is achieved equilibrium concentration (cycle 7).

In the proposed method, the MSE of the awn rotational motion of the rope-material 4 can be changed using the computer in the method of applying the manufacturing environment on a rope-material 4. This can also be done at a constant speed. As shown by practical experiments, only a few cycles of rotational motion sufficient to cover rope manufacturing environment. Typically, this number is significantly less than five cycles. As mentioned above, the processing environment may be printed on the cable material even during one cycle, if the computer 29 is programmed accordingly.

In the case discussed here, the device manufacturing environment is introduced into the nozzle 6 (Fig 3) and thus is applied to the cable material 4.

Alternative or additionally, a new method can be designed so that the manufacturing environment can be applied on the cable material before and/or after the nozzle 6 to the path along which moves the cable material. This is schematically shown in figure 1. The pipe 31 is designed to supply the manufacturing environment, which is taken from the exhaust pipe 21, connected to the housing 9 above the roller 5, which has a check valve (control valve), which can be adjusted by the computer 29.

Thus, the cable material entering the nozzle 6 has applied thereto the manufacturing environment. On this site pipe 31 does not necessarily have to be connected with this section through the roller 5. Depending on the given conditions, the pipe 31 can b is to be introduced somewhere between the roller 5 and the opening of the Venturi nozzle 6. Besides, there are other constructions in which the pipe connection 31 is in the vertical trajectory of the rope-material 4, which lies between the storage 8 and the roller 5, and the manufacturing environment has already been done before rope-material 4 reaches the roller 5.

In figure 1 such modification is shown by the dotted line. This design has a discharge port 31, provided with a control valve 32A, which may be controlled by computer 29.

In addition, the nozzle 33 may be provided in the discharge port 33, which, for example, departs from the exhaust pipe 21 and which also has a control valve 34 controlled by computer 29. This way you can apply the coating from the manufacturing environment on a rope-material 4 after the nozzle 6 or, alternatively, additional coverage.

The coating process of the manufacturing environment of the cable material 4 is controlled by computer 29. But this method can also be regulated on the basis of data that are typical for coatings applied to a moving rope-material 4, and these data can be obtained in the way of coverage. These data are processed by computer 29 in his home or a special control program that uses a mathematical model, based on the control program. For this purpose, provided is relevant to the respective sensors, marked on figure 3 positions 35 and 36. The sensor 35 monitors directly rope-material 4, and the sensor 36 monitors the manufacturing environment. The parameters controlled in this way can be pH, concentration of dye (diluted) in the treated environment, etc. but they can also be factors related to the cable material, which can be scanned optically or otherwise.
