Definitions
- the invention is in the field of spinning technology and relates to a Spinning machine according to the first independent claim. Furthermore, the Invention a spinning arrangement with such a spinning machine.
- Fiber material in the form of a longitudinal structure e.g. fiber ribbon, sliver or roving
- a suitable container jug
- a coil fed a suitable fiber material educated.
- the actual yarn formation takes place for example by ring spinning, pot spinning, Bell spiders, friction spiders, open rotor spiders, air spiders etc, each Spinning station for the yarn formation and winding of the formed yarn necessary parts of the device.
- These device parts of all spinning stations are usually via a common drive or a small number of common drives and are for individual spinning positions (thread break, Can change) can be disconnected from this drive.
- the spinning machine has refinement means, ie means for refinement Stretching such longitudinal structures or means for dissolving such longitudinal structures.
- the Refiners are typically for all spinning positions or for a number of Spinning stations provided jointly, but can also, like the means for yarn formation be provided per spinning station.
- Means for refinement before yarn formation by stretching the supplied Longitudinal fiber structures have, for example, three cylinder pairs arranged in series, which are driven in the conveying direction with increasing peripheral speed. Such pairs of cylinders extend, for example, along a series of Spinning stations and are, for example, by appropriate gears from one single drive or there is one for each pair of cylinders (drive function) separate drive provided.
- drive function drive function
- Means for refinement before yarn formation by dissolving the supplied Longitudinal fiber structures have, for example, one feed roller for each spinning station Opening roller and the fibers in the dissolved state from the opening roller to Yarn formation leading fiber guide channel.
- the whole the feed rollers and the entirety of the opening rollers each by a common Drive driven.
- the yarns formed in the individual spinning positions are, for example, online or periodically monitored by sensors and spinning positions that fail, are decoupled from common drives.
- the decoupling can only do that Yarn formation or additionally the refinement preceding the yarn formation affect.
- a plurality of so-called regulating drafting systems are used, in which one A plurality of incoming longitudinal fiber structures (for example from a card or from upstream regulating drafting system) and the fiber mixture is stretched.
- Mass measurements at the entrance and / or exit of the drafting device Stretch ratio controlled or regulated, in that the speed at least of a pair of cylinders in the drafting system is changed.
- Such drafting devices obtain the longitudinal fiber structures from storage containers (cans) and lay the produced ones Longitudinal fiber structures also in storage containers from which the Longitudinal fiber structures finally a spinning machine or a spinning station are fed.
- the management of these storage containers is very complex, especially if it is to be carried out fully automatically. Without automation or with only partial automation is the management of the storage containers labor intensive and prone to errors.
- the object of the invention is to create a spinning machine, the yarns can produce high regularity with regard to fiber mass per unit length, even if the fiber material fed to the spinning positions is less high Has regularity than for known spinning machines for the same Yarn quality would have to be required.
- the spinning positions of the spinning machine according to the invention in the sense of a continuous spinning process and if between upstream devices providing the longitudinal fiber structures and Spinning positions, for example, areas with free sag of the fiber longitudinal structures as Buffers are provided, it is also possible to operate within limits set by the Spinning processes and by the formation of the spinning station are predetermined, the performance of the individual spinning positions to the filling level of the buffer or to the performance of the adapt upstream device. To do this, a spinning station as a whole for driven an increase or decrease in their performance.
- a buffer for one direct connection of a device providing a longitudinal fiber structure and one Spinning station of the buffer machine to be provided according to the spinning machine according to the invention can, for example, connect a card and a draw frame Buffer memory, which is known from the publication WO-99/11847, correspondingly be adjusted.
- Another advantage of the spinning machine according to the invention is that for the Piecing (after thread break or can change) refining agents and if necessary, yarn forming agents can also go through a piecing cycle is completely independent of other spinning positions and in which the speeds of moving parts, for example, increase continuously. This is the piecing significantly easier than with state-of-the-art machines in which moving parts only when spinning onto one with constant speed running drive can be coupled, resulting in a stepped or leads to at least a very steep increase in the corresponding speeds.
- sensor means of the spinning machine according to the invention detect each spinning position the mass of fibers in the area of the entrance of the refining agent and the infeed speed becomes the refinement agent by appropriate Control of the refining agent varies accordingly.
- Applicable control methods are known from regulating drafting systems or cards are usually used as regulation (closed loop control) from the actuator downstream measuring element and / or as a control (open loop control) with realized by the actuator upstream measuring element. Thereby with the Regulation usually compensates for relatively long-wave fluctuations and with that Control of relatively short-wave fluctuations.
- Fluctuations in the fiber mass are essentially the delay in the spinning station Fiber mass varies, in that the speed of entry of the fiber mass into the Spinning station and / or the speed at which the yarn runs out of the spinning station is controlled or regulated accordingly.
- the fiber longitudinal structures become the spinning positions advantageously supplied from cans or from coils, so that devices that the Longitudinal fiber structures deliver from fluctuations in the entry speed into the Spinning positions are not affected.
- Ring spinning, open end and friction spinning processes are less suitable for the above outflow regulation described, since for these processes the yarn properties in only narrow areas are independent of the spinning speed. A wider one Area in which the yarn properties are independent of the spinning speed, still has the pot spinning process. However, this procedure is because of relatively large, rotating masses not very much for a discharge regulation suitable.
- FIG. 1 shows very schematically a spinning station of an exemplary embodiment of the spinning machine according to the invention.
- the spinning station has its own drafting device 1 (refining agent 1) with, for example, three cylinder pairs (inlet cylinder 2, middle cylinder 3 with straps 4 and outlet cylinder 5) as internal spinning unit refining means 1.
- the spinning station has a yarn-forming means 6, which for example consists essentially of a nozzle arrangement 7 and a pair of take-off cylinders 8 for an air spinning process, as well as a yarn winding device 9.
- a first mass sensor 10 is provided upstream of the inlet cylinders 2 of the drafting device 1, which detects the fiber mass of the longitudinal fiber structure supplied to the drafting device 1.
- a second mass sensor (so-called yarn cleaner) is provided between the draw-off cylinder pair 8 and the yarn package 9, which detects the fiber mass of the yarn produced.
- the measurement data generated by the sensors 10 and 11 are fed to a control and monitoring unit 12.
- Inlet cylinder 2 and middle cylinder 3 of the drafting system 1 are from a first Motor M.1 driven in such a way that the longitudinal fiber structure between them Cylinder pairs experiences a constant advance.
- the speed of the engine M.1 is variable and is detected by a speed sensor Z.1.
- the engine M.1 is by means of Control data from the control and monitoring unit 12 based on the measurement data of Sensors 10 and 11 are generated, controlled.
- Outlet cylinder 5 of the drafting device 1 and take-off cylinder 8 of the yarn forming means 6 are operated by a further motor M.2 driven such that their peripheral speeds are one for the present Have a suitable yarn formation ratio (spinning delay).
- the speed of this other motor M.2 is detected by the speed sensor Z.2 and with suitable means kept constant.
- the stretching arrangement according to FIG. 1 essentially corresponds to an arrangement such as it is known per se from regulating drafting systems.
- the control and monitoring unit 12 processes the measurement data of the in a manner known per se from regulating drafting systems Sensors 10 and 11 to control signals based on the speed of the first motor M.1 is regulated. This will result in a suitable delay due to the Sensor 10 detected irregularities in the fiber mass compensated by Variation of the inlet speed (inlet cylinder) and variation of the warpage between central cylinders 3 and outlet cylinders 5 (variable draft 20).
- This control can be used to correct short-wave irregularities in particular be evened out. Irregularities in fiber mass from downstream sensor 11 on the finished yarn are detected in processed in the same way, this being a regulation that can not even out short-wave irregularities.
- the spinning station shown in FIG. 1 thus has a controlled in a known manner or regulated drafting system, the infeed speed being varied and the The outlet speed is constant, that is, the yarn formation with constant Delivery speed can be operated.
- the outlet speed is constant, that is, the yarn formation with constant Delivery speed can be operated.
- a spinning machine therefore has a large number (for example two hundred) spinning stations, all of which are equipped, such as those in the Figure 1 shown spinning station.
- the M.2 can be connected to the other motor All or a plurality of the spinning stations can be coupled and also the Control and monitoring unit 12 can be the entirety of the spinning stations or one Serve majority of them. At least those are assigned to each spinning station individually Pairs of inlet cylinders 2 and middle cylinders 3 of the drafting system, the sensors 10 and 11 and the first motor M.1 or a stepless replacement for this motor controllable gear between a central drive and each spinning station.
- the fiber longitudinal structures from the spinning positions Supply containers fed.
- a direct and continuous feed for example from a card or from a draw frame is only possible if between the Spinning station and the upstream device a buffer with a sufficiently large Buffer capacity is arranged with which buffer variations in the Infeed speed can be bridged into the drafting system without that the upstream device must be controlled accordingly.
- a Buffer can simply be designed as a free sag of the longitudinal fiber structure, which sag is monitored by sensors.
- the spinning station When exceeding a lower or upper limit of the buffer capacity, the spinning station is stopped or a Upstream device (card, drafting system) controlled accordingly, so that Delivery speed to the fill level of the buffer and / or to the Infeed speed in the spinning station internal drafting system is adjusted.
- a Upstream device card, drafting system
- a stretching controlled internally according to FIG. 1 and constant Yarn formation is particularly applicable for spinning processes for which a change the delivery speed of the yarn formation a change in the yarn properties would require or for which a relatively rapid change in delivery speed yarn formation is not possible for mechanical reasons.
- Such spinning processes are for various reasons, as already mentioned above, for example Ring spinning process, friction spinning process, pot spinning process, Bell spinning process and open-end rotor spinning process.
- FIG. 2 again shows a spinning station with a drafting unit 1 internal to the spinning station and yarn-forming means 6 for a spinning machine according to the invention, as shown in FIG.
- the same parts are labeled with the same reference numbers.
- the first motor M.1 is operated at a constant speed and the further motor M.2 is controlled accordingly.
- irregularities with regard to fiber mass which are detected by sensors 10 and 11, are compensated for by varying the outlet speed (outlet cylinder 5) from the drafting system, which requires corresponding variations in the delivery speeds of the yarn-forming agent 6.
- a control / regulation of the spinning positions of an inventive Spinning machine with spinning stations according to Figure 2 is particularly suitable for one direct and continuous feeding of fiber longitudinal structures to the spinning stations and for Spinning process, the delivery speed without influencing the Yarn properties are variable over a relatively wide range.
- Such spinning processes are, as already mentioned above, in particular air spinning processes. Since the Infeed speed to the spinning unit-internal drafting system can be constant buffering before this entry or at least to a large buffer capacity to be dispensed with.
- FIG. 3 shows a spinning station for a spinning machine according to the invention, in which spinning station the control / regulation according to FIGS. 1 and 2 are essentially combined. While the motors M.1 and M.2 have variable speeds and are controlled by the control and monitoring unit 12, only the middle cylinder pair 3 is operated by a third motor M.3 at a constant speed. This results in two places of variable delay 20 and 20 '. For such control / regulation of the spinning stations, limit values must be specified for the first variable warping, the second variable warping, the spinning speed, further spinning parameters and, if appropriate, for buffer capacities upstream of the drafting unit 1. The operation of each spinning station must be kept or set within the specified limits, if it is not possible to operate without crossing borders.
- the control unit can also control the delivery speed of a device (card or drafting device) upstream of the spinning machine, which supplies several spinning stations directly and continuously with fiber material, in such a way that the capacity is optimally utilized, i.e. the upstream device and the spinning stations are operated in this way ( or not operated for spinning positions) that the output of yarn is maximum.
- a device card or drafting device
- the control unit can also control the delivery speed of a device (card or drafting device) upstream of the spinning machine, which supplies several spinning stations directly and continuously with fiber material, in such a way that the capacity is optimally utilized, i.e. the upstream device and the spinning stations are operated in this way ( or not operated for spinning positions) that the output of yarn is maximum.
- the spinning station instead of the preliminary delay (position variable Delay 20 ') or in addition also the spinning delay (variable delay 20 ") be included in the control.
- the spinning station according to FIG. 3 is also suitable for a performance variation of the Spinning station as a whole to adapt this performance to the delivery performance of a upstream device or device providing the longitudinal fiber structure to be spun to spin on.
- FIG. 4 again shows a spinning station with a spreader-internal drafting system 1 for a spinning machine according to the invention, as is already shown in FIGS. 1 to 3.
- the sensors 10 for a control and 11 for a long-wave control there are further possible sensor positions 10.1 (between the inlet cylinder 2 and the center cylinder 3 for a control), 11.1 (between the center cylinder 2 and the outlet cylinder 5, immediately after the variable draft 20, for a relatively short-wave control) and 11.2 and 11.3 (between outlet cylinder 5 and nozzle arrangement 7 and between nozzle arrangement 7 and discharge cylinder 8, both for regulation).
- the measurement data from sensor positions 10 and 10.1 upstream of the variable draft 20
- the measurement data from sensor positions 11, 11.1, 11.2 and 11.3 are used for draft regulation.
- each spinning position of the spinning machine according to the invention Arrange mass sensor, as already mentioned in connection with Figure 1 advantageously two, one upstream and one downstream of the Variable delay 20 is to be arranged.
