Definitions
- the present invention relates to a method for
- latent tensions arise in the yarn, which cause the yarn to have a tendency to untwist in the tension-free state and to form loops and loops.
- This behavior of the yarn is commonly referred to as curling tendency.
- the tension arises primarily during spinning itself, but can also be caused by further processing, e.g. caused by winding operations and the like.
- the curling tendency leads to a substantial impairment of the further processing of the textile yarn and must therefore be eliminated.
- the yarns are usually steamed to remove the curling tendency, steaming taking place at temperatures between approximately 50 and approximately 150 ° C.
- the lower temperature range up to approx. 90 ° C e.g. rather for
- Woolen yarns and the upper temperature range are more used for synthetic yarns.
- the quality requirements for the steaming process are very high because of uneven Vapors, for example, create tension threads in the fabric or the absorption of colorants in a dyeing process becomes uneven.
- the steaming methods known in the prior art usually work with saturated steam. Wet steam can stain the yarn due to its condensate content, while superheated steam has poor heat transfer values.
- the devices used for steaming In order to have saturated steam available at temperatures below and above 100 ° C., the devices used for steaming must be designed in such a way that the pressure prevailing in them can deviate upwards or downwards from the ambient pressure. Usually used for steaming
- Vacuum steaming has the advantage that there is less air in the system, which makes steaming more uniform.
- the DE-Z provides an overview of vacuum steaming.
- these spinning bobbins are now fed to a continuously operating winding machine, they have to be collected in appropriate yarn trolleys and inserted into the autoclave. Then they have to be transported to the winding machine. The material flow required thereby not only requires
- the present invention has for its object to provide a method for steaming yarn, by means of which a uniform steaming of the yarn is achieved with little expenditure of time and with little expenditure of energy. Furthermore, it is the object of the present invention to provide a device for steaming yarn, through which a uniform steaming of the yarn can be achieved with a low expenditure of energy and time and which requires only a small amount of space and construction.
- the method according to the invention and the device according to the invention should work in such short cycles that they can be included in a continuous process of yarn processing.
- This object is achieved by the method according to claim 1.
- An apparatus for performing the method is the subject of claim 11.
- Number of yarn packages is subjected to the damping and by using a vacuum bell that can be evacuated very quickly in a very short time.
- Vacuum bell is connected to a steam generator, in which water and saturated steam are enclosed at steam temperature and a pressure which essentially corresponds to the steam pressure of the water at the selected steam temperature, and the thermodynamic state variables in the vacuum bell are practically abruptly adapted to the state variables in Steam generator instead. It is in
- the steam generator and preferably also the vacuum bell are largely kept exactly at the steam temperature, the amount of energy required for the evaporation does not lead to a significant drop in the temperature level. Keeping the temperature level constant is made considerably easier in that the vacuum bell is kept correspondingly small. Compensation is particularly easy if, according to a preferred embodiment, the vacuum bell only receives a single yarn package. Furthermore, the temperature drops due to the
- the sleeve and the yarn can, according to a preferred development of the invention, preferably be preheated via hot air before the vacuum bell is evacuated .
- the vacuum bell is preferably also ventilated after preheating with preheated hot air. This prevents an uneven temperature drop in the yarn.
- the yarn is dried immediately after steaming. This can be done in the same bell in which the yarn was steamed. It is also possible to have a second one Provide a vacuum bell that is used only for drying.
- Drying is preferably carried out by evacuating the vacuum bell used for drying. Due to the then decreasing pressure in the bell, the pressure exceeds
- Vapor pressure of the hater steam on the yarn is the ambient pressure, so that most of the steam as superheated steam directly through the vacuum pump
- An evacuable condensation container is preferably provided, which is connected upstream of the vacuum pump. Cooling in the condensation container can ensure that the temperature prevailing there is lower than that in the
- Vacuum bell prevailing temperature Due to the thermodynamic laws, the steam from the vacuum bell then flows very quickly into the condensation container.
- the colder container thus acts like a powerful pump, through which the water vapor is drawn out of the vacuum bell.
- the temperature of the condensation container can be adapted to the desired final vacuum pressure.
- a vacuum end pressure of 20 mbar roughly corresponds to a saturated steam temperature of 17oC.
- the device according to the invention is characterized by a structure whose external dimensions are only a fraction of the dimensions of a conventional autoclave.
- the device has a steam generator and at least one vacuum bell, which can be evacuated via a vacuum pump.
- Vacuum bells are adapted to the space required by one or more yarn packages.
- an ent speaking control device is provided, which can preferably be combined with a control device which controls the entire sequence of the device.
- This control device is connected to a large number of temperature and pressure sensors, which detect the state variables in the individual system parts.
- the control device which preferably has a computing processor, operates according to a predetermined program and outputs control signals in order to control a number of control valves which are required to connect the vacuum bell, the vacuum pump and the steam generator to one another in the predetermined cycle sequence.
- Another very significant advantage of the device according to the invention is the extremely low energy consumption. Due to the small dimensions and the short cycle times, the energy consumption, based on one yarn unit, is e.g. on a spinning cop, only a fraction of the effort required for autoclave damping.
- the steam temperature is kept essentially constant during the operation of the system.
- it is desirable that at least the vacuum bell used for steaming is heated in such a way that the temperature of its inner wall essentially corresponds to the desired steaming temperature.
- this is brought about by electrical heating wires which are integrated in the vacuum bell and to which so much electrical energy is supplied that the desired temperature is reached.
- the heating of the vacuum bells is brought about by integrating heating tubes through which a liquid, preferably water, flows, integrated in the vacuum bells.
- the heating pipes are in a flow connection with the water in the
- This version has the advantage that a control device for temperature control of the vacuum bell can be omitted.
- the same vacuum bell that is used for steaming is also used for drying. Drying takes place by connecting the vacuum bell to an evacuated vacuum container via a corresponding valve device, as a result of which the pressure in the vacuum bell drops rapidly.
- the residual moisture required by the yarn package for further processing in some applications can be determined beforehand within narrow limits by choosing the negative pressure in the vacuum bell used for drying.
- a different vacuum bell is used for drying the yarn package than for steaming.
- the device has at least two vacuum bells that are operated in cycles, the The bobbin is first steamed in the first vacuum bell and then dried in the second vacuum bell.
- the system further preferably has a hot air generator in which air is preheated to a predetermined temperature, which is preferably equal to the steaming temperature, in order to use it for preheating and venting the vacuum bell.
- a predetermined temperature which is preferably equal to the steaming temperature
- the individual yarn packages are therefore placed on the transport plate.
- This attachment can be carried out using handling devices known in the prior art, which are therefore not described in detail.
- the transport plates slide in a slide rail which has a holding profile which corresponds to an inverted T, into which correspondingly designed parts of the plates engage.
- the plates have pins provided with one or more through holes, onto which the yarn packages can be placed directly, and are arranged in the slide rail during continuous processing so that they are immediately adjacent. When the rearmost plate is pushed further, all other plates are therefore automatically moved forward by the corresponding displacement path.
- a damping bell and a drying bell are then located above the slide rail and can be raised and lowered by a pneumatic device. Also newly developed sealing measures ensure that the
- Vacuum bells automatically when pressed onto the plate are sealed against this. Furthermore, holes are provided in the slide rail at this point, which are also automatically sealed when the vacuum bells are pressed on.
- the vacuum bell or vacuum bells are connected to the steam generator etc. through the holes in the slide rail.
- the plates with the yarn packages located thereon slowly move through the steaming and drying system, the cycle time in one exemplary embodiment for steaming or drying being approximately 2 minutes.
- Processing capacity is thus 30 yarn packages per hour. If a larger processing capacity is required, several steaming and drying bells can be arranged in parallel.
- the slide rail then has a corresponding branching, and the incoming stream of plates with yarn packages is divided, for example, into four individual slide rails. With ten bells arranged parallel to one another, a processing capacity of 300 yarn packages per hour can then be achieved, which should be sufficient for most applications, but can be increased without problems by further parallel arrangements.
- the bells arranged in parallel are raised and lowered by a common device.
- the device according to the invention can be designed so that it is suitable for any type of yarn package.
- These textile containers are usually produced by winding a textile yarn on sleeves, which consist, for example, of metal or plastic or the like.
- sleeves which consist, for example, of metal or plastic or the like.
- other container shapes are also conceivable.
- the method according to the invention also works without any problems if yarn packages are used which have a high
- the package is used and only one package is processed per vacuum bell, the inside of the
- Vacuum bell preferably also cylindrical.
- the device can e.g. be arranged directly between a ring spinning machine and a subsequent winding machine.

- the embodiment is designed for steaming yarn that comes from ring spinning machines and is wound on cylindrical metal sleeves or plastic sleeves.
- the yarn 1 schematically indicated in the drawing is on a cylindrical sleeve 2 made of plastic wound up, whereby a spinning cop 3 is formed.
- the spinning cop 3 is transported with a plate 5 through the device, wherein it remains on this plate 5 even during the damping and drying process.
- Plate 5 is essentially rotationally symmetrical about an axis 6 and has a conical section 7 which is delimited at the top (i.e. towards the spinning cop) and at the bottom by a flat circular ring surface 8 or 9. Below this conical section there is a first cylindrical section 10 with a smaller diameter and then a second cylindrical section 11 with a larger diameter.
- a cylindrical pin 12 is arranged on the upper circular ring surface 8 and has a bevel 12a at its upper end (facing the spinning cop).
- the outer diameter of the cylindrical pin 12 is slightly smaller than the inner diameter of the sleeve 2, so that the sleeve 2 can be pushed onto the pin 12 and is held by the latter.
- a cylindrical bore 13 arranged coaxially to the axis 6 runs through the plate 5, the purpose of which will be explained in detail below.
- the lower annular surface 9 also has a cylindrical extension 14.
- the plate is made of metal, preferably aluminum.
- the plate 5 is displaceably arranged in a slide rail 20, which is only shown in part in FIG. 1.
- the slide rail 20 has a guide groove 21 which extends essentially perpendicular to the plane of the drawing in FIG. 1.
- the guide groove 21 consists of an upper, narrower region 22 and a lower, further region 23.
- the guide groove 21 thus has the shape of an upside-down T in cross section.
- a cylindrical Bore 24 arranged, the function of which will be explained later.
- In the upper area of the slide rail 20 is one
- Indentation 25 is provided, the width of which is slightly larger than the diameter of the cylindrical extension 14 of the plate 5.
- spring bodies 26 are embedded in the slide rail, essentially rotationally symmetrically to the axis of the cylindrical bore 24.
- the spring body 26 consist of a cylindrical hollow body 27, in the interior of which a spiral compression spring is arranged.
- the hollow body 27 is at its upper end with a flange
- annular sealing groove 32 is also provided.
- a commercially available O-ring 33 is embedded in this sealing groove 32.
- the bell 35 has a substantially cylindrical
- Metal body 36 which is closed at the bottom by a flange 37.
- a flange 37 On the flange 37, an upward-pointing cylindrical web 38 is arranged concentrically to the longitudinal axis 39 of the bell.
- the cylindrical metal body 36 of the bell is formed in one piece with the bell
- domed lid 41 completed. There are two in the cover 41, offset with respect to the longitudinal axis 39 of the bell
- Threaded socket 42 and 43 arranged.
- a pressure sensor 44 is in the first, shorter threaded connector 42 screwed and a temperature sensor 45 in the second, longer threaded connector 43.
- the cylindrical metal body 36 of the bell is surrounded by a heating wire 55.
- the bell also has a
- Insulation 56 which is to largely prevent heat transfer from the cylindrical metal body 36 to the ambient air.
- annular recess 57 On the underside of the flange 37, on the surface facing the plate 5, concentrically to the longitudinal axis 39 of the bell, there is an annular recess 57 in which a second O-ring 58 is arranged.
- the function of this bell is now as follows: the bell can be raised and lowered along its longitudinal axis 39 by a pneumatic cylinder. The bell is located
- the spring body 26 causes the plate 5 to be pushed onto the O-ring 33 at a vertical distance from the latter. This prevents damage to the O-ring 33 when the plate 5 is pushed. If the plate 5 is not in the position shown in FIG. 1, the cylindrical extension 14 of the plate lies directly on the Slide on. As a result, any wear when the plate 5 slides is limited exclusively to the area between the cylindrical extension and the slide rail.
- the lower circular ring surface 9 itself and the upper circular ring surface 8, which should keep their original state as far as possible with regard to the sealing or the contact with the spring bodies, are not changed by wear.
- 2 shows a functional diagram of the device for steaming yarn according to the invention. In this device, a bell 36 is used as the first bell 71 for damping

- Withstand negative pressure up to 20 mbar absolute pressure
- a higher excess pressure up to approx. 5 bar absolute pressure
- the upper design value of the system is essentially determined by the maximum treatment temperature of the yarn. If, for example, only a temperature of 120 ° C is to be achieved, a maximum pressure of 2 bar absolute (corresponding to the steam pressure of the water at 120 ° C) is sufficient, only temperatures below 100 ° C used, the system only has to be dimensioned in relation to the necessary negative pressure.

- the condenser 73 is connected to a vacuum pump 92 via a line 91.
- a cooling device 93 which cools a cooling medium which flows through supply lines 94, 95 into a schematically indicated cooling spiral 96 within the
- Capacitor 74 flows.
- a drain line 97 with a valve 98 is provided on the underside of the condenser 74.
- the condenser is connected via a line 100 both to the steam supply device for the damping bell 71 and to the steam generator 73, one of which
- the hot air generator 75 is also designed for pressure testing and is insulated from the environment
- a heating coil 106 is provided to heat the air in the hot air generator.
- Devices of the damping system essentially have three main lines, namely a first main line 111, a second main line 112 and a third main line 113.
- the main lines 111 and 113 are connected to the line 87 of the steam generator 74.
- the main line 111 is also connected to the hot air generator 75 via corresponding valves, as explained below.
- the second main line 112 is open at one end to the environment and is connected at its other end to the main line 111 in front of the hot air generator 75.
- the third main line 113 is also connected to line 87, which comes from the steam generator 73, and on the other hand is connected to line 100, which leads to the condenser 74.
- the first main line 111 and the second main line 112 are connected to one another via a connecting piece 115, which continues to lead to the bore 24 of the slide rail in the region of the damping bell 71.
- the main line 111 is also connected via a line 117 to the bore 24 'of the slide rail in the area of the drying bell 72, this line on the the other side is open to the environment via a valve 118.
- control unit 130 The operation of the device is controlled and regulated by a control unit 130.
- the control unit 130 a control unit 130, a
- Process computer which e.g. can be constructed on the basis of one of the known microprocessors, receives the signals from all sensors and gives the control signals with which the heating of the bells 71, 72, the steam generator 73 and the hot air generator 75 and the cooling of the condenser 74 is controlled - or control signals for all valves and the control signals for the movement control of the plate 5.
- the entire control and regulation takes place via a program stored in the control unit 130. An operator can make the desired
- Control variables i.e. above all, the temperature at which steaming is to be carried out using a suitable data medium, e.g. insert a floppy disk, a tape, a punched tape or a keyboard into the control unit.
- a suitable data medium e.g. insert a floppy disk, a tape, a punched tape or a keyboard into the control unit.
- control device 130 the entire function of the system is controlled by the control device 130.
- the data required for steaming i.e. essentially the steam temperature and the steaming times are either predefined in the control unit or, as described, are entered into the control unit before starting
- a valve 141 in the main line 113 is opened briefly so that the steam generator (still under normal pressure) and the condenser (with 20 mbar absolute pressure) are connected to one another.
- the absolute pressure of the system drops to a value that is initially far below 473 mbar. Since the steam pressure of the water at 80 ° C is above this pressure value now prevailing in the steam generator, practically suddenly enough water is converted into steam that the saturated steam pressure of 473 mbar is established.
- the prerequisite for this is that the temperature level in the entire system is kept at 80 ° C. As already stated above, this is achieved in that all essential parts of the system are constantly kept at this temperature.
- the steam generator 73 now contains water at 80 ° C. and steam at 80 ° C. at a pressure of 473 mbar. After this preparatory measure, the first spinning cop 3 can on the plate 5 on the slide 20 under the
- Steaming bell 71 are conveyed.
- the pneumatic actuation devices of the steaming bell lower the steaming bell and press it onto the plate 5
- a valve 142 in the first main line 111 is then opened, as a result of which the interior of the steam bell is connected to the condenser 74 via the bore 24.
- the initial vacuum of 20 mbar absolute pressure has been restored in the condenser 74 by the vacuum pump 92. It is thereby achieved that in the steaming bell and in the yarn package in a very short time, which is generally less than 20 seconds, a corresponding vacuum of likewise approx.
- the valve 142 is then closed again and the valves 144 and 145 are opened.
- the valve 145 is designed as a needle valve and can therefore be regulated in a particularly metered manner.
- the bell 71 is now connected via the main line 111 and the line 87 to the steam generator 73, in which a temperature of 80 ° C. and a saturated steam pressure of 473 mbar prevail. It should be pointed out that the damping bell 71 is constantly kept at this temperature by the heating systems and by the temperature sensors.
- the saturated steam enters the bell 71 through the bore 24 and the hollow sleeve 2. It should be noted that the sleeve 2 of the spinning cop 3, which is shown in the figure, is not perforated. Rather, the steam enters the bell bell 71 on the upper open side of the sleeve.
- the steam can reach all layers of the yarn unhindered.
- the inner wall of the damping bell and the other parts of the system have a temperature that corresponds to the saturated steam temperature, steam condensation on these surfaces is avoided. If in some applications the temperature difference between the sleeve of the yarn is still too high after the yarn has been introduced into the damping bell and after the evacuation, the sleeve can be preheated by using a
- Valve 146 to the hot air generator shortly before
- Evacuating the bell 71 is opened.
- hot air flows into the damping bell via the main line 112 and heats the sleeve and the yarn. Since the supplied hot air is kept at the temperature level of the saturated steam temperature, i.e. in the example at 80 ° C, the hot air supply does not cause overheating. This effectively prevents the condensation of the steam in a sleeve that is too cold.
- Valve 146 can be opened again and the steaming bell is thereby ventilated with hot air. Since the
- Hot air has the same temperature as the steaming temperature, there is no re-steaming. Then the bell 71 is raised and the spinning head is conveyed further with the transport plate 5 and comes into a position under the drying bell 72. The drying bell 72 is moved up and down simultaneously with the damping bell and is sealed off from the slide rail in the same way as in the case of the Damping bell 71 is the case.
- the drying time is approximately 2 minutes in order to achieve a desired, uniform and reproducible residual moisture in the yarn, which enables immediate further processing of the yarn.
- dried amount of yarn for further processing e.g. can be fed to a winding machine.
- FIG. 3 schematically shows a conveyor belt 200, as is known in the prior art, for conveying spinning bobbins or similar yarn packages.
- the conveyor belt 200 which is deflected via a roller 201, has pins 202 on which the spinning heads 3 are placed.
- Rows 207, 208 are bells used for steaming, while rows 210, 211 contain bells used for drying.
- a total of five damping bells 209 and a total of five drying bells 212 are arranged in each row.
- a second conveyor belt 205 is provided, which is designed in the same way as the conveyor belt 200.
- a slide rail system 220 is arranged in the central region of the device, which in the exemplary embodiment shown consists of five
- the slide rails are all designed in the manner explained with reference to FIG. 1. Plates move on the slide rails, as were also explained with reference number 5 in relation to FIG. 1.
- Handling device (not shown), which is known in the prior art, converts the spinning heads conveyed by the conveyor belt 200 onto the plates 5.
- the sliding device 240 consists of a transversely arranged rod 241 which can be moved towards and away from the slide rails by means of a double-acting cylinder 242 (pneumatically or electrically operated). As soon as the cycle time for steaming or drying the previously processed cops is finished, the
- Control device a signal, and the steam bells and the drying bells are lifted.
- the slide device 240 pushes all the plates on the slide rails 221, 222, 223, 224 and 225 by two plate divisions to the left. As a result, these ten plates are pushed under the vacuum bells 207, 208 used for damping. At the same time, those previously located under the steam bells
- FIG. 5 shows a detail of the device according to FIGS. 3 and 4, namely the mechanism for raising and lowering the bells.
- the slide rails 231 etc. are arranged at a distance above a floor surface.
- two cylinders 250, 251 which have extendable piston rods 252, 253.
- Parallel to the arrangement of the slide rails is a support device 254 which is fixedly connected to the piston rods 252, 253 and is arranged essentially horizontally.
- the twenty vacuum bells are attached to this support device 254, as can be seen in the top view of FIG. 4.
- Fig. 6 shows a further detail of the device, namely the mechanism for moving the plates.
- the plates have, as has been explained with reference to FIG. 1, a bore 13 through which, for example, during the damping of the Steam is supplied. This hole is also used to move the plates.
- a longitudinal cylinder 260 is provided, which is arranged horizontally and parallel to the slide rail 234.
- a short stroke cylinder 261 is perpendicular to the direction of displacement of the piston rod 262
- Fig. 7 shows a top view of the transport device according to Fig. 6. It can be seen that e.g. the slide rail 234 has a longitudinal slot 270 in the drive area, into which the piston rod 262 of the short-stroke cylinder 261 engages. The longitudinal slot allows the piston rod to move in the slide rail in the desired manner.
- the vacuum bell 280 is substantially eight-shaped, i.e. it has two mutually merging inner wall surfaces, each with a circular cylindrical diameter.
- the axes of two spinning heads 3 are arranged coaxially to each of these circular cylinder cross sections. In this embodiment, two spinning heads can therefore be accommodated per vacuum bell, the total volume of the nonetheless
- Spinning heads is very small and there is still an exact alignment of the position of the spinning heads with respect to one another and the spinning heads with respect to the inner wall of the vacuum bell.
