Method and apparatus for making knitted fabric

The present invention relates to a method for manufacturing a knitted fabric according to the preamble of claim 1. The invention also relates to a device for carrying out the method according to the invention.

In the past, there have been a number of proposals for making knitted fabrics directly from staple fibers or rovings. Thus, the traditional intermediate stage of spinning is the formation of yarn, which is wound onto a bobbin and possibly rewinded. The knitted fabric can be produced with significantly greater economic value.

For example, the document US-A-3,877,254 teaches the delivery of staple fibers to the needle of a knitting machine. The device takes a circular knitting machine as an example for the description. The short fibers are arranged in a circle by a brush, extracted by a wheel having a hook, and then transferred to a circular knitting machine which is formed into a knitted fabric of short fibers. The interlacing points in the grid give the knitted fabric the necessary strength. It also shows that the auxiliary line of the yarn can also be woven into it.

Document WO 2004-079068 describes a circular knitting machine in which the woven area is replaced by a roving of short fibers for the yarn. In the draw frame system, the roving is extended to the desired number of yarns and transferred to a needle such as an unreinforced fiber tampon. The draw frame as described in WO 2004-079068 has three or more rollers with a double apron and a pair of transporting pressure rollers, ie a ring spinning machine for spinning as in the prior art . For large circular knitting machines with larger cylinder sizes, for example, can be set 48 Or 96 weaving zones, which propose to provide a swirling nozzle between the draw frame and the weaving zone, wherein a false twist is provided to the drawn fiber sliver. This type of temporary reinforcing yarn has sufficient strength to be conveyed for a longer distance. On the other hand, the false twist should be loosened during the process of reaching the weaving zone so that the fibers are substantially parallel to each other when the needles are combined into a knitted fabric, so that the flawlessness of the yarn makes the knitted fabric feel soft.

Since the processed roving is significantly less expensive than the full spun yarn, direct processing of the fiber tampon made from the drawn roving has a high commercial profit. However, this temporary reinforcement has the disadvantage that the fiber slivers that are brought together by false twisting are not always reliably transferred from the exit of the extension system to the needle without interruption. Short pauses in fiber slivers may occur repeatedly. These usually do not cause the knitting process to stop, due to the high conveying speed of the fiber tampon - up to 200 m / s or more - the thread monitoring will not even be touched; in addition, other fiber tampon immediately found its arrival weaving The thread of the needle. The momentary break in the supply of the fiber tampon results in radial or axial holes in the knitted fabric. However, these holes mean that the knitted fabric is completely unacceptable.

Accordingly, it is an object of the present invention to provide a method of overcoming the disadvantages of the method and apparatus for making a knitted fabric from roving. Forming a method and an associated device allows for the manufacture of a trouble free knitted fabric from the roving. It has the cost advantage of using roving directly. The knitted fabric has a comfortable feel.

This task is based on a feature described in item 1 of the scope of the patent application. The feature of the sign portion is shown for the method of manufacturing a knitted fabric from roving. This task is also achieved by a related device which is characterized by the features of the characterizing portion of the patent application scope of the stand-alone device. Further refinements and/or other advantageous embodiments of the invention are the subject matter of the patentable scope of the various related methods and apparatus.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for making a knitted fabric in which a fiber tampon is drawn to a desired fineness in an extension system of the aforementioned knitting needle provided for each knitting machine. Each fiber tampon is permanently reinforced in the path from the extension system to the needle. The continuously reinforced fiber tampon can be found at the needle.

Since the fiber tampon is continuously reinforced in the path from the extension system to the needle, the problem of a momentary break in the supply of the fiber to the needle is completely overcome. This false tampon can also be transported for longer distances in view of the fact that the false twist that would result in the interruption being observed can be quickly resolved. This reinforcement is stable and can be verified in the fiber tampon at the needle. This continuous reinforcement can also be verified in the manufactured knitted fabric. This continuous reinforcement is different from the effective yarn defect, but is sufficient to give the fiber tampon sufficient strength. Thus, the soft feeling of the manufactured knitted fabric is not greatly affected.

In still another preferred embodiment of the invention, the continuously reinforced fiber tampon is achieved by winding a fiber around the center of the fiber tampon, wherein the fibers are substantially flawless and are arranged parallel to each other. The cross-sectional area of the center of the fiber tampon shows that the fiber accounts for a large proportion. The surrounding fibers are wound around the circumference of the center and overlap and interconnect with each other. In this way, the transmitted fiber tampon achieves a moderate stability without the need to simultaneously form an effective yarn (for example in a ring ingot) The same as that formed in the worsted machine).

For reinforcement, the fiber tampon is efficiently transported from an extension system to a needle path by a pneumatically operated spinning nozzle (air spinning nozzle). It forms a stable state but can be transported. The fiber tampon includes a center around the fiber. By adjusting the relevant operating parameters of the spinning nozzle (such as the capacity, speed and extent of the vortex flow), the tampon can be made It is roughly parallel. This operating parameter depends on the type of fiber used and the degree of reinforcement desired, and may be determined by a technical expert based on experience supplemented by a simple series of experiments.

For reasons of space, such as when a circular knitting machine is used, this space is advantageous if a plurality of rovings are stretched to a desired fineness in an extension system and are substantially parallel to each other. Fiber slivers from the extension system are fed to the spinning nozzles next to each other, each spinning nozzle being assigned to an associated extension system.

In a preferred embodiment, for servicing, the spinning nozzle is disposed in an extension system that is supplied by a common source of compressed air. For example, if a spinning nozzle is attached to a particular extension system for repair or replacement, the spinning nozzle on the other extension system will not be affected, as if compressed air would be supplied to each extension system independently of each other. The spinning nozzle is not affected. It is true that all spinning nozzles may also be supplied by a central compressed air system; each spinning nozzle or group of spinning nozzles may still be individually disconnected, but does not impair the supply of compressed air to other spinning nozzles. .

It is advantageous if air from the outlet of the spinning nozzle is introduced into a conduit between the spinning nozzle and the knitting needle. At the same time, the catheter is used for introduction The continuously reinforced fiber tampon is applied to the needle. The gas stream supports the transfer of the fiber tampon through the conduit.

An apparatus for manufacturing a knitted fabric according to the present invention comprises a knitting machine having a knitting needle having at least one woven region for processing a supplied fiber tampon into a knitted fabric, and an extension system before the woven region It pulls a roving into a fiber tampon with the desired fineness. The device is located between the extension system and the needle and will continue to reinforce the fiber tampon from the extension system.

In yet another preferred embodiment of the invention, the means for continuous reinforcement of the fiber tampon is a pneumatically operated spinning nozzle (air spinning nozzle). Pneumatic spinning nozzles or air spinning nozzles of this type are well known and available from the prior art.

For reasons of space, two or more rovings can be stretched in parallel in an extension system. In an embodiment of the invention, the center distance of the respective two or more spinning nozzles of each extension system is between 8 mm and 30 mm. At this intermediate interval, the tampon is transferred to the spinning nozzle through an extension system without changing their orientation.

The spinning nozzle and an extension system are advantageously connected to a common source of compressed air. Thus, the separate spinning nozzle or set of spinning nozzles can be operated independently. The dependence of a spinning nozzle or a group of spinning nozzles on the compressed air system does not affect the supply of compressed air to other extension systems.

In a further embodiment of the invention, a conduit for the continuously reinforced fiber tampon is positioned between the spinning nozzle and the needle while being adapted to receive air from the outlet of the spinning nozzle. Especially when the transmission distance is long, The catheter ensures that the continuously reinforced fiber tampon can be safely and continuously delivered to the needle. They are also suitable for carrying away compressed air from the spinning nozzle. In this way, the fibers contained in the air and the consequent contamination of the knitting machine can be avoided.

In a further particularly advantageous embodiment of the invention, the extension system before the spinning nozzle has a tensile element and an associated drive engine, the shaft of the system being at 90° to a chassis and the longitudinal ends thereof being Connected to the chassis. For example, the extension system can be operated as a multi-cylinder draw frame with inlet and outlet roller pairs. The shaft of the pair of drive rollers connects the chassis to a longitudinal end and is at about 90 to the chassis. The tensile element and the floating configuration of the associated drive engine have design advantages and allow for a very compact and easy to maintain structure. A significant benefit of the extension system is that it is provided as a stand-alone device that can be installed and moved without causing difficulties for adjacent extension systems. Therefore, the downtime of the knitting machine will be short.

A further advantageous variant of the invention combines a wire magazine and a transport device between the extension system having the spinning device and the needle of the knitting machine. The line library and conveyor operate as a positive feeder and operate in synchrony with the knitting machine and always provide a constant amount of continuous reinforcing fiber tampon. In another embodiment, the line library and conveyor system operate as a stock feeder, typically supplying the required amount of material in accordance with the needs of the knitting machine. The storage feeder is typically operated in synchronism with the drive of the extension system. It can also be a hybrid feeder that can be selectively operated as an active feeder or a storage feeder. In this way, the yarn can be supplied in a continuous (active) or intermittent manner, for example in order to smooth the knitted fabric (single Face) or jacquard knitted cloth change between. The knitting machine and the drive of the extension system can be completely disconnected from each other for the knitting/threading connection process. Thus, when the knitting machine is stationary, the continuously reinforced fiber tampon can be first rotated through the extension system or the spinning nozzle. They may be supplied manually to the wire guide of the knitting machine through the yarn feeder. The knitting machine is then activated.

The device according to the invention can be a knitting machine of any type and size. Spinning nozzles and independent extension systems for use in a circular knitting machine as described herein will be more justified. The yarn feeder combination is particularly advantageous for a circular knitting machine such that the extension system is located at a great distance from the cylinder and can therefore be correspondingly disposed around a large circumference. This is advantageous for spatial relationships.

Figure 1 shows the basic principle of the apparatus for producing a knitted fabric directly from drawn rovings of the present invention. According to a preferred embodiment, the device comprises a circular knitting machine 1 having a syringe 3, for example with 48 or 96 needles 4, in particular a latch needle type, movably mounted thereon. Of course, it is also possible for the device 1 to replace the circular knitting machine with a flat knitting machine. For example, the needle 4 feeds a roving Y directly into the weaving zone, which may for example be from a draw tampon of a drum or a roving from a flyer 5 of the flyer. The woven area 2 is fitted to the roving Y to enter the position of the knitting needle 4 at the barrel 3. The circular knitting machine 1 is drawn after a stretching system 6 at a tampon in which the roving Y is drawn into a desired fineness. For the sake of clarity, only one extension system 6 is shown in FIG. Some embodiments of the present invention have separate weaving zones for each individual extension system. However, it can also be done by one A common extension system provides stretched fiber tampon for two or more woven areas. In that way, the two rovings Y parallel to each other are simultaneously pulled to an expected fineness in the extension system.

A device 11 is provided between the extension system 6 and the knitting needle 4 for the purpose of continuously reinforcing the fiber tampon Y pulled out by the extension system 6. The means 11 for stabilizing the fiber tampon Y is preferably a pneumatic spinning nozzle. A spinning nozzle of this type is also known as an air-spinning nozzle, as is known from the document EP-A-1 518 949 or EP-A-1 826 299. A spinning nozzle 11 is provided to each of the fiber slivers Y from an extension system 6. Two or more spinning nozzles 11 can be used in the same extension system 6.

The spinning nozzle 11 is coupled to an upper extension system 6, preferably connected to a common source of compressed air. Thus, the single spinning nozzle 11 or a group of spinning nozzles can be operated independently. The dependence of a spinning nozzle or a group of spinning nozzles on the compressed air system does not affect the supply of compressed air to other extension systems.

The continuously reinforced fiber tampon Y from the spinning nozzle 11 can be fed directly to a woven zone 2, where it is processed into a knitted fabric by the knitting needle 3. The continuous reinforcement of the fiber tampon Y can be visualized at the knitting needle 4 and the processed textile. In another embodiment, there may be a conduit 12 between the spinning nozzle 11 and the knitting needle 4 for permanently reinforcing the fiber sliver Y, which simultaneously receives air from the outlet of the spinning nozzle 11. . Especially when the conveying distance is long, the duct ensures that the continuously reinforcing fiber tampon can reach the knitting needle 4 safely and without interruption. In addition, it can take away compressed air from the spinning nozzle 11. In this way, the fibers contained in the air and The resulting contamination of the knitting machine can be avoided.

Figure 2 shows a schematic representation of a continuously reinforced fiber tampon Y within the spinning nozzle. The fiber tampon has a center C in which the fibers are set to be substantially flawless and parallel to each other. Due to the flow of air within the spinning nozzle, the outwardly facing fibers are wound around the center of the fiber tampon. These wound fibers T surround the center C of the fiber tampon Y. The size of the center accounts for a large proportion of the fiber. The surrounding fibers T surround the circumference of the center C and overlap and interlace with each other. In this way, the transmitted fiber tampon Y achieves a moderate degree of stability, and it is not necessary to simultaneously form a spinning which is effective as in a ring-type spinning machine.

The extension system 6 shown in Figure 3 is a three-cylinder draw frame for stretching slubbing. The roving is a roving Y that already has a certain twist. Thus, the spun yarn can be wound onto a roving bobbin which can be easily mounted on a bobbin of a knitting machine, in particular a circular knitting machine. The sufficient strength of the spun yarn makes it possible to transport a relatively long distance without problems. In order to stretch the spun yarn Y to a predetermined degree of the spun yarn as much as possible, the twist contained therein must be stretched to a sufficiently fine degree before entering the main stretch zone, and is preliminary in the draw frame. The stretch zone is released. In the three-cylinder draw frame 6, the preliminary stretch zone extends from the pair of inlet pinch rolls 7 to the apron roll for the double apron 8. This preliminary stretching is produced by different circumferential speeds of each pair of rolls, preferably in the range of 1.2 to 1.4. The main stretch zone extends from the double apron 8 to the pair of exit pinch rolls 9. The roving yarn is drawn in the main stretch zone by a factor of between 25 and 50.

As can be seen in Figure 3, the entire extension 6 is constructed in a complete set and placed on a base 60, each having a top roller 71, 81 or 91 and a lower syringe 72, 82 or 92. a lower needle cylinder 72, 82 or 92 of the pinch roller pair 7, the apron roller of the double apron 8 and the pair of outlet pinch rollers 9 are mounted on the shaft, and the shaft is fixed to the base 60 One end, and the outward extension is not fixed. The upper inlet roller 71 and the upper apron roller 81 are mounted with bearings on the mounting plate 78, which are attached to the base 60 by a force spring 75. The tension spring 75 extends in a support bearing from the base 60 to a thrust point 77 provided on the mounting plate and is loaded by a clamping cam 76 having a pivot disposed on the base 60. The spring forces the upper inlet roller 71 and the upper apron roller 81 against the lower inlet needle 72 or the lower apron needle 81, respectively. This initial clamping force can thus be adjusted by the clamping cam. The upper exit roller 91 has a bearing on the bracket 96 that is free to move the base 60. The bracket 96 is biased by a plate spring 93 which is fixed at one end to a projection 95 of the base 60. The upper exit roller 91 is provided only on the bracket 96, and the upper exit roller 91 can be easily pulled out from the lower exit roller 92 against the tension of the leaf spring 93.

As shown, a roving guide 10 is provided at the entrance of the extension device 6 and before the inlet pinch roller pair 7. The upper rollers 71, 81 of the inlet pinch roller pair 7 and their apron rolls having double aprons 8 are spring loaded by the stretching means 75, 76, 77, 79 against each associated lower needle Cartridges 72, 82. The upper exit roller 91 is stretched by a plate spring 93 fixed to the chassis 60 and abuts against the lower outlet cylinder 92. The lower syringes 72, 82, 92 are driven by drive motors 62, 63; these are also attached to the base 60 and extend come out. The motors 62, 63 are preferably synchronous motors that are controlled by frequency conversion. The drive mechanism (transmission gear, drive wheel, toothed belt) of the lower syringe is located at the rear of the base 60 and is protected from contamination by a cover 64.

The apparatus of Figure 3 is substantially different from the three- or multi-cylinder draw frame of the conventional ring-type spinning machine. In these cases, however, the pinch roller and the lower needle barrel of the draw frame of two adjacent weaving zones are disposed on the same shaft, they are usually clamped at least at their ends and are also always at the center of the shaft. Support, the present invention proposes a completely independent extension device 6, the tensile element of which is only fixed at one end and is provided on the base 60 by means of a cantilever beam. Unlike conventional draw frames, the upper exit roll is pressed against a continuous lower needle barrel by a spring, each of which has its respective output pinch roll pair. The configuration of the adjacent extension system is therefore no longer located around the lower barrel of the same line. Instead, each extension device operates as an individual that does not rely on the adjacent extension device.

The pinch roller pairs 7, 8, 9 and the mating drive motors 62, 63 have an axis at an angle of about 90 to the base and are attached to the vertical side of the base 60. The floating arrangement of the tensile element and the associated drive motor has design advantages that make it a very compact and easy to maintain structure. A significant benefit of the extension system is that it is provided as a stand-alone device that can be installed and moved without causing difficulties to nearby extension systems. Therefore, the downtime of the knitting machine will be short. Such stand-alone devices are particularly advantageous for circular knitting machines when they can be mounted at an angle to adjacent components. This allows all the knitting zones of the circular knitting machine to be supplied with the drawn roving.

The numeral 1 in Fig. 4 is the whole circular knitting machine, which has a line library and transmission. The device 100 is delivered. This type of line library and transfer device 100 is a yarn feeder as is known in the prior art, and the two terms may be synonymous in the following. In Fig. 4, the same elements have the same reference numerals as in Fig. 1. The circular knitting machine 1 is in turn connected to a cylinder 3, for example in which 48 or 96 knitting needles 4, in particular tongues, are arranged. The knitting needles 4 are continuously supplied to the continuously stretched rovings Y, which may be, for example, draw frame rovings from a cylinder placed on the creel of the circular knitting machine 1 or rovings from the roving bobbin 5. . In the extension system 6, the roving Y is stretched to a predetermined fineness of the fiber tampon and is continuously reinforced in the spinning nozzle 11.

The line library and conveyor 100 are stored intermediately as the drawn and continuously reinforced transfer tampon Y. During the weaving/threading process, the wire library and conveyor 100, the circular knitting machine 1 and the drive of the extension system 6 can be completely or partially disconnected from each other. This allows a fiber tampon Y in transit to be first produced by the extension system, followed by the spinning nozzle 11, without the need to start the operation of the circular knitting machine 1 and/or the yarn feeder. The formed transportable fiber tampon is conveyed to the yarn feeder 100, from which it is conveyed to the circular knitting machine 1. Only when the continuously reinforced fiber tampon Y is placed in the wire guide 13 of the circular knitting machine 1, the machine starts to start. This involves combining the circular knitting machine and the drive of the extension system 6 with the drive of the yarn feeder. The inlet cutting device 101 or the outlet cutting device 102 is located before and after the yarn feeder 100, monitors the interruption of the fiber tampon Y, and cuts the circular knitting machine 1 and the extension system 6 when the wire is broken.

The yarn feeder 100 can be operated as a storage feeder. For example, a rotating wire drum has a first circumferential portion and a second circumferential portion, the first A circumferential portion is coupled to a belt in the form of a belt that is detached from the belt. If the fiber tampon is located between the first circumferential portion and the conveyor belt, it will be forcibly and continuously fed to the needle of the knitting machine to correspond to the wire drum or the conveyor belt (active feeder) The speed of the peripheral speed. On the other hand, if the fiber tampon is located in the second circumferential portion, it is conveyed only when it is required and supplied to it by the knitting machine (intermittent yarn feeder). A storage feeder of this type, including the improved one, is known from DE 41 16 497 A1. The configuration of the storage feeder 100 between the extension system 6 and the subsequent spinning nozzle 11 produces the transferable strong fiber tampon Y, so that the knitting machine 1 is optionally permanently (positively Or intermittently supplied, for example, to change between a smooth knitted fabric product (single-sided) or a jacquard knitted fabric.
