Abstract

The heatsetting container according to the invention is suitable for treating a bundle of threads from an adjustable plurality of threads by means of a heatsetting process in a continuous operation and in a vertical position of the heatsetting container.

Description

Heat Setting container

The technical field of the invention relates to the heat setting of a thread or of a bundle of a plurality of threads, in particular of yarns of natural materials and / or synthetic materials. Heatsetting is used in particular to improve yarn quality after spinning or twisting textile yarns.

Heatsetting refers to the thermal process, which usually takes place in a steam atmosphere or dry heat, to provide the fibers, yarns, or fabrics produced with dimensional stability or other desirable properties, e.g. to give greater volume, resistance to wrinkles and increased temperature resistance.

Furthermore, all processes with which a textile material, such as a thread or a bundle of filaments, at least one of the aforementioned properties is imparted by means of temperature and / or moisture, are referred to as heatsetting, heat set or set processes ,

At the filing date of the present application, a description of the heatsetting is available at the web site http://en.wikipedia.org/wiki/Heatsetting. Furthermore, such Heatsetting processes or Heatsetting systems from DE 9 018 165 Ul or DE 4 022 924 Al known. In these a modular construction of the Heatsetting systems is described, which consist of several chambers for the pretreatment and treatment of the textile threads. The textile threads pass through the treatment sections on a conveyor belt. The yarn or threads are in several layers Laying layers are each different with the treatment medium, such as steam, penetrated. Thus, the yarn is disadvantageously treated inhomogeneous.

A similar problem arises when instead of the conveyor belt, a rope or a transport belt for transport through the horizontal Heatsetting plant is used. The Applicant has found that the net weight of the thread or the bundle of fibers during the horizontal operation of Heatsetting plant has a negative effect that the contact points of the thread on the rope or the conveyor belt in the finished carpet are visible. Such support points visible on the finished carpet disadvantageously reduce the quality of the produced carpet.

The document DE 10258262 Al describes a heating device and a method for heating a thread, in particular for a shrinkage treatment of a textuierten thread. The heating device has an elongated heating channel, which has a thread inlet and an opposite thread outlet at the front. The heating channel is uniformly heated by a heating medium surrounding the heating channel by means of a mantle-shaped heating medium. In the interior of the heating channel, a free flow cross section is formed for the passage of the thread, wherein the heating channel has a layer in which forms a natural air flow due to a chimney effect between the thread inlet and the thread outlet within the heating channel. Further, the heating channel is assigned a control means by which the air flow caused by the chimney effect between the yarn inlet and the Fadanauslass is variable.

The document DE 16 10 940 describes a method and egg Circular transport arranged by a circulating around one end of Tranεportmittelgruppe yarn guide, while simultaneously shifts the stored on said end yarn turns along the transport, thereby subjecting treatment and unwinds at the other end of the transport group again, the transport group rotatably and stationary is held.

Further, WO 02/06575 A1 discloses a method and apparatus for the continuous treatment of synthetic threads in a heat exchange chamber in which the thread to be treated comes into direct contact with the heat exchange medium. At the thread outlet opening and at the thread inlet opening in each case acted upon with a sealing medium sealing device is provided with a arranged in the vicinity of the thread outlet or the thread inlet feed line for the sealing medium. The sealing medium is kept away from the thread passing through the heat exchange chamber. This is done by discharging the sealing medium in front of the heat exchange chamber or by discharging the heat exchange medium together with the sealing medium. In the vicinity of the heat exchange chamber, a discharge for the sealing medium is arranged. The heat exchanger is also designed to be split, so that the thread can be inserted by the removal of one part.

Accordingly, it is an object of the present invention to provide a Heatsetting container, with the threads can be treated as homogeneously as possible.

Furthermore, it is an object to provide a Heatsetting container, with the threads as homogeneous as possible and can be treated in the most cost-effective and particularly simple way. It is also an object to provide a Heatsetting container with improved usability.

According to the invention, at least one of these objects is achieved by a Heatsetting container with the features of claim 1.

Accordingly, a heatsetting container is proposed which is adapted to treat a filament bundle of an adjustable plurality of filaments by means of a heatsetting process in a continuous operation and in a vertical position of the heat setting container.

An advantage of the present invention is that due to the vertical operation of Heatsetting container uniform support of the thread bundle on a transport device in the Heatsetting container can be made possible, so that the weight of the thread bundle on the homogeneity of the treated bundle of fibers or to be treated threads is minimal.

Another advantage of the present invention over known heatsetting equipment is that the heatsetting container of the present invention requires much less installation space, particularly because of its vertical operating position.

In addition, the present invention has the advantage that not only a thread, but a bundle of filaments with an adjustable plurality of threads is treated simultaneously. Thus, a separate treatment unit is not necessary for each individual thread. Thus, the costs are reduced according to the invention. Moreover, according to the invention, Advantageous embodiments and modifications of the invention will become apparent from the dependent claims and the description with reference to the drawings.

According to one embodiment of a Heatsetting container, the Heatsetting container on a head part, a central part, a bottom part and a traversing and tilting device. The traversing and tilting device is adapted to move the heatsetting container to the vertical position with the headboard closed and the bottom closed, and / or the heatsetting container to the vertical position or a horizontal position or an angular position of adjustable angle between the vertical position and the horizontal position with open headboard and / or with open bottom part and / or swung-middle part to drive. The traversing and tilting device advantageously allows an automatic dismantling of the Heatsetting container. Furthermore, they can be approached by the various positions of the Heatsetting container.

According to a preferred embodiment of the invention, the Heatsetting container is operable in the vertical position with swung-middle part in a continuous test operation.

According to a further preferred embodiment, the Heatsetting container comprises: an insertion device, which introduces the bundle of fibers along a longitudinal axis of the Heatsetting container in a main shaft of the Heatsetting container, and / or a transmission device with a fixing gear and a to hold the transport gear such that it is independent of a rotational movement of the main shaft, wherein the transport gear is adapted to suppress a speed of the main shaft with a predetermined ratio to a reduced speed and to drive at least one roller chain for transporting the thread bundle at the reduced speed ,

According to a further preferred embodiment, the fixing gear has: a first hollow shaft which can be coupled against rotation on the main shaft; a first gear, which is arranged around the first hollow shaft, is fixed to a frame of Heatsetting container and is rotatably supported outwardly and inwardly, a housing which is coupled to the first hollow shaft and in particular hermetically encapsulated, a second gear, which is coupled to the housing and is adapted to run as a mating gear about the first gear, a third gear, which is coupled to the second gear via an axis, wherein the second gear and the third gear are mutually supported against rotation, a fourth gear which is disposed about the first hollow shaft and rotatably supported outwardly and inwardly, wherein the third gear is adapted to run as a counter-wheel to the fourth gear, and a channel which the bundle of filaments up to a branching point between the first gear and the fourth gear axially leads and leads out radially from the branch point.

According to a further preferred embodiment, the transport gearbox has: a worm gear with a screw arranged on the second hollow shaft and two worm wheels arranged radially to the worm, and at least one deflection gear with two bevel wheels, wherein in each case a bevel gear drives a roller chain via an angle drive of 45 °.

According to a further embodiment of a Heatsetting container, a predetermined number of roller chains for transporting the thread bundle through a Dämpfbereich the Heatsetting- container is provided, each roller chain having a predetermined number N of chain links and in at least a predetermined number M of vertical planes, the respective chain links the roller chains of a common vertical plane each have a driver.

According to a further preferred embodiment of the driver is designed as a coupled to the chain link bow member which provides one or two support points for the wound around the roller chains thread bundle. The design of the transport device for the thread bundle through the Dämpfbereich the Heatsetting container as roller chains, which carriers with defined support points for the thread bundle, has the advantage that the yarn bundle rests homogeneously and evenly on the transport device by providing the defined support points and further that the thread bundle does not catch during the withdrawal process.

In accordance with a further embodiment of a heatsetting container, there is provided a winding-wing extraction device which is suitable for transporting the material, which has been transported by means of the roller chains through the damping region, onto the roller chains adjust chanische tension of the withdrawn thread bundle. The winding-wing take-off device allows a radial withdrawal at the radially offset to the main shaft withdrawal point and thus advantageously an improved withdrawal behavior as a result of the defined deduction of exactly one thread bundle. This advantage becomes particularly clear when compared to a head-on or flying-shaft extraction. Furthermore, it is advantageously not necessary for the winding-wing take-off device to be driven, since the winding-wing take-off device always rotates with the tensile load on the thread bundle. For this purpose, therefore, advantageously no additional supply of energy is necessary.

According to a further preferred embodiment, the winding-wing take-off device comprises a take-off device with a hub arranged on the main shaft, a radial feed-through device coupled to the hub and a connecting piece coupled to the feed-through device, which pulls the bundle of fibers from the withdrawal point offset radially to the main shaft and into the feed device leads, and / or an eddy current brake coupled to the draw-off device, by means of which the tension of the withdrawn bundle of filaments can be adjusted.

According to a further embodiment of a Heatsetting container, the Heatsetting container has an inlet region for insertion and winding of the thread bundle, a Dämpfbereich in which the bundle of threads is treated by the Heatεetting Prozesεes, a cooling area in which the treated bundle of fibers is cooled, and a Control device on. The control device regulates an actual steam temperature of the steaming area as a function of the actual steam temperature of the steam bath Temperature of a second air-vapor mixture of the cooling region to a predetermined target steam temperature for the damping region, in particular by means of a supply of compressed air in the inlet region.

According to another embodiment of a Heatsetting container chain guide means for guiding the roller chain between an upper sprocket and a lower sprocket and adjusting means for adjusting the distance of the chain guide means and the lower sprocket from the winding core with fixed upper sprocket are provided for each roller chain.

The use of a mast transport system with the roller chains and the chain guide devices allows the wound bundles of fibers to be treated from two sides. The wound bundle of threads divides the damping region into two treatment chambers, an inner treatment space between the winding core and the wound bundle of filaments, and an outer treatment space between the wound bundle of filaments and the housing of the heatsetting container. By steaming from both sides results in an improved moisture transport and thus a better penetrability of the yarn. Due to the improved moisture transport the glass point temperature decreases and consequently the necessary energy supply decreases.

After the thread bundle is wound on the roller chains in the area of the fixed upper sprocket, the shrinkage of the threads of the wound thread bundle can be adjusted by adjusting the distance between the chain guide device and the lower sprocket and the winding core. This is especially possible because the me Standes in contrast to the mechanical tension of the wound-up thread bundle in the region of the upper sprocket, so the winding area is adjustable. Thus, at a set operating temperature of the Heatsetting container threads can be made with different shrinkage depending on the set distance between the chain guide devices and the winding core.

In accordance with a further embodiment of a heatsetting container, a texturing device, which precedes the damping region, is provided, which textures the threads of the introduced bundle of fibers. The texturizer texturises the threads or yarn to produce textured yarns or textured yarns, examples of texturing means are given in the textbook "Complete Textbook Glossary", published in Celanese ACETATE, page 160 ff. ,

Furthermore, a system is proposed with a heatsetting container as explained above and a texturing device which precedes the heatsetting container and which textures the threads of the bundle of filaments to provide textured threads.

By means of the eddy current brake 16, the tension of the withdrawn bundle of fibers 2 is adjustable. Preferably, the winding-wing take-off device 14 has a force sensor (not shown), which measures the mechanical tension of the withdrawn bundle of fibers 2, by means of which the eddy current brake 16 can be regulated to set a desired thread tension. For this purpose, for example, a control device (not shown) is provided. The winding-wing removal device 14 transfers the withdrawn bundle of fibers 2 of the thread deflection device 17 in the direction of the longitudinal axis of the heatsetting container 1.

Without limiting the generality, only two chain guide means 47a and 47b for two roller chains 25a and 25b (not shown) are shown in FIG. The chain guide 47a, 47b is suitable for guiding the respective roller chain 25a, 25b between an upper sprocket 24 and a lower sprocket 48.

The adjusting device 49-53b is suitable for adjusting the distance of the chain guide device 47a, 47b and the lower sprocket 48 from the winding core 12. In this case, the upper sprocket 24 is fixed.

After the thread bundle 2 in the region of the fixed upper sprocket 24 on the roller chains 25; 25a-25d, the shrinkage of the filaments of the wound-up filament bundle 2 can be adjusted by adjusting the distance between the chain guide means 47a, 47b and the lower sprocket 48 and the winding core 12, respectively. This is possible in particular because the mechanical tension of the wound-up bundle of filaments 2 in the region of the chain guide devices 47a, 47b can be adjusted by adjusting the distance in contrast to the mechanical tension of the wound-up bundle of fibers in the region of the upper sprocket 24, that is to say the take-up area. Thus, at a set operating temperature of the heatsetting container 1 threads with different shrinkage depending on the set distance between the chain guide means 47a, 47b and the winding core 12 can be made. In order to enable the setting of the distance between the Kettenführungεeinrichtung 47a, 47b and the winding core 12, the respective Kettenfüh For example, according to the embodiment of Fig. 14, the chain guide 47a has two joints 54a, 54b.

Preferably, the adjusting device 49-53b has an upwardly and downwardly rotatable adjusting nut 49, at least one thrust ring 50a, 50b with rollers 51a, 51b, at least one push rod 52 and at least one ramp surface 53a, 53b. For example, an upper thrust ring 50a and a lower thrust ring 50b are provided. Via the adjusting nut 49 and at least one push rod 52 disposed between the adjusting nut 49 and the thrust rings 50a, 50b, the thrust rings 50a, 50b can be moved up or down in a vertical direction. Between the thrust rings 50a, 50b and the chain guide means 47a, 47b, a ramp 53a, 53b is arranged in each case.

When the respective thrust ring 50a, 50b is moved upwards, the rollers 51a, 51b pass over the respective ramps 53a, 53b and push them outward against the chain guiding devices 47a, 47b. Thus, the Kettenführungs- devices 47 a, 47 b pressed outward and the distance between these of the winding core 12 is increased. On the other hand, if the adjusting nut 49 is moved downwards, the rollers 51a, 51b can roll back on the ramp surface 53a, 53b. To reset the chain guide device 47a, 47b, a return device (not shown) is provided, which is designed, for example, as a tension spring and is arranged between the respective chain guide device 47a, 47b and the winding core 12.

Although the present invention has been described above with reference to the preferred embodiments, it is not limited thereto but modi? Ed in a variety of manners is also another position, such as a horizontal position of the Heatsetting container conceivable.
