Abstract

A textile spinning rotor incorporates interchangeable components which, when exposed to ultra-violet light of a first pre-defined wavelength and visible or infra-red light in a second wavelength range, emit light of a pre-determined wavelength. The rotor is installed within a spinning machine in close proximity to two types of light source. Second wavelength light emission from the spinning rotor identifies the rotor and the presence or absence of the rotor surface finish or coating. Also claimed is a selective light detection assembly which registers the color codes. Further claimed is a spinning assembly incorporating the color-detection system and a commensurate indicator display.

Description

The invention relates to an interchangeable component of a textile machine a surface coating or coating and an optical marking and a detection device.

EP 0 922 797 A2 describes a spinning rotor for an open-end spinning machine known, in which on the outer circumference of the rotor plate Identification mark is arranged. The identification mark will Non-contact read by a sensor on a control unit is arranged. The one with the sensor device based on the identification mark detected signals are compared with data in a control device and the control unit refuses to re-spin the open-end spinning machine, if the signals of the identification mark are not agree with specified data. This ensures that only safety-related spinning rotors are used. As A barcode or a transponder are proposed for identification marking. The sensor device detects the identification mark optically or inductively. The identification mark is attached here complex and requires separate steps in the manufacture of the Spinning rotor.

A spinning rotor is also known from EP 1 035 241 A1, in which on A label is arranged on the outer circumference of the rotor plate Standstill of the spinning rotor is visually recognizable by an operator. In order to however, automatic control of the spinning rotor cannot be implemented.

It is therefore an object of the invention to provide an interchangeable component of a textile machine, especially a spinning rotor, with a surface coating or remuneration and an optical marking, in which the marking is inexpensive to manufacture and securely detectable, and a Provide detection device for reliably detecting such a component.

This object is achieved with the features of claims 1, 18 and 26, respectively.

According to claim 1, an interchangeable component of a textile machine a surface coating or coating provided in the special Color elements are stored. When the color elements are irradiated with light do the color elements or the surrounding area emit light of a special, predetermined wavelength or a specific predetermined Wavelength range. Because of the emission of this second wavelength or the second wavelength range, the component itself can be identified and / or the presence of the surface coating or - Compensation or the component is recognized. With the targeted storage of A desired light emission is reproducibly brought about by color elements, so that random effects are excluded or suppressed. A surface coating is any coating that is based on the pre-processed component is applied, for example around a special Surface quality with regard to roughness, friction and / or a Achieve improved durability by increasing wear resistance. The surface of the component blank is used for surface finishing modified near the surface. For example, through storage of elements or phase change in the near-surface area. Of course, a coating can be used in addition to the surface coating be provided or the coating is close to the surface Material modification of the component.

At least the coating or coating is particularly advantageous Provided in an area of the component that is subject to heavy wear and / or heavy pollution is subject to wear and / or pollution of the component.

Becomes a type of interchangeable component with these in the coating or remuneration stored color elements provided, for example be recognized that this component has special quality requirements enough. For example, heavy-duty spinning rotors become uniform with a first Color marking (for example red emission) if this for Suitable speeds of up to 120,000 revolutions per minute are. Other types, for example, only for speeds up to 100,000 revolutions per minute can be used with yellow-emitting color elements to be provided as a second color marking while spinning rotors which are suitable for speeds of up to 80,000 revolutions per minute, Coatings or coatings with green-emitting color elements have as third color marking. A corresponding color-graded Wavelength emission can of course be interchangeable with all others Components of a textile machine are provided if different Types are available for different purposes. Thus, the application or the allowable operating parameter range indicated by different color emissions.

Depending on the type of storage of the color elements in the coating or Remuneration and depending on the color elements themselves, the emitted Light by reflection, luminescence or phosphorescence or a combination generated from this. Luminescence or phosphorescence effects are preferred used, where a wavelength shift between Excitation light and emission light occurs.

The exciting first wavelength or the first wavelength range and the emitted second wavelength or the Wavelength range different. This avoids that Detection of the emission light only by the exciting wavelength Multiple reflection or scatter gets into the detection detector and so incorrectly due to the presence of the coating or coating is closed with the color elements. Usually there is a wavelength shift due to the color elements of a shorter, stimulating Wavelength to a lower, emitted wavelength or wavelength ranges occur. It is advantageous to excite with UV light and the emitted wavelength or the wavelength range is in the visible range, so that a user can view the component by looking at it with radiation Can identify UV light. In contrast, is the emitted wavelength or Wavelength range in the infrared, there is a larger selection of potential Color elements on the one hand and on the other hand are inexpensive Sources for stimulating the color elements are available. For example LEDs that emit in the visible or infrared range.

The surface coating or coating is a particularly advantageous one, a wear-reducing coating or coating, so that it can be checked by emission of the second wavelength or the second wavelength range whether it is still present in sufficient quantity or at the desired location during the service life of the component is. In the case of a friction-reducing layer or coating, sulfide (MoS ₂ ), Teflon and / or graphite particles are incorporated.

Depending on the necessary coating or coating, depending on the excitation or emission wavelength and the technical possibility to Evidence of the color elements at certain points or locations of the The component can have different types of color elements or types of embedding of the color elements chosen in the coating or coating become. With a homogeneous coating or coating (without storage of particles) can be the color elements as chemical elements or Molecules or as particles (e.g. nanocrystallites). For coatings, that of a mixture of matrix and this embedded Particles can exist, the color elements as chemical substances in the Matrix or the embedded particles can be integrated or even particles be stored in the matrix. Finally, before the actual Coating a coating or coating with the color elements take place so that they emit as long as the overlying coating is still there. In the latter case, for example The intensity of the emitted light increases as the coating decreases, until finally the emission stops when the layer with the color elements is worn.

If the color elements themselves are specially embedded particles in the nanometer or micrometer range, a wavelength of the emission is reproducibly achieved since the emission itself is not further influenced by the environment, for example by the matrix. The same applies if the color elements are embedded, for example, as impurity atoms in the particles of the original coating, for example in the diamond particles or ceramic particles. For example, ruby particles are Al ₂ O ₃ particles in which chromium or chromium oxide (Cr ₂ O ₃ ) is embedded, and which then glow in the familiar ruby red. Furthermore, laser-active solid materials are known which, when excited with (flash) light, emit on a desired (laser) wavelength. An example is YAG (yttrium aluminum garnet), which is doped with rare earths (such as neodymium (Nd - 1.064 µm), erbium (Er - 2.94 µm) or holmium (Ho - 2.1 µm)) and each emit at different wavelengths after rare earths. Porous semiconductors (Si, SiC) down to the nanocrystalline range also fluoresce when excited with UV light.

The components can be marked particularly easily if the color elements are printed on the component.

The color elements can be invisible to the human eye without tools be, if appropriate detection devices are provided are.

A particularly reliable detection of the dye elements of a coating or compensation of an exchangeable component takes place with the detection device according to claim 20. By a lighting device Light of a first predetermined wavelength or a predetermined one Wavelength range emitted and the light emitted by the component with a light detection device specifically at a second predetermined Wavelength or a second predetermined wavelength range is detected. This stimulates the remuneration or coating and the Detection of the detected wavelength in a defined, fixed manner, so that Interference effects such as scattered light can largely be excluded.

The lighting device advantageously comprises a light-emitting diode or laser diode, that emit on a narrowband wavelength range. at the laser diode is additionally obtained a directed light beam, so that the Alignment with the coating or coating is simplified. Become In addition, light guides are used, so that the light guides can be Jobs. With a color or ribbon edge filter the light detection device filters out stray light and a setting to the desired second wavelength to be detected or second wavelength range reached.

When using the detection device on a rotor spinning machine points this advantageously a data storage device with which the presence or absence of the detection signal registered by the detection device becomes. This can be used, for example, to identify when a wear layer is present worn out, or if not suitable in the case of quality problems Components could be the cause. The detection device is particularly advantageous provided on the maintenance device, so that only a detection device for monitoring the components on the individual Machining points is necessary.

The detection device or when using optical fibers is advantageous the sensor head of the detection device by an extension device the maintenance device of the processing point or the one to be recorded Part delivered. When registering a spinning rotor as replaceable Component is advantageously the detection device or the corresponding Detection head on the extension unit with a cleaning module provided so that only one extension unit is necessary for both.

To control the equipping of a spinning station with at least one replaceable one Component according to claim 32 is a display and / or interrogation device intended. For example, this is an LCD display with a or multiple lines or a monitor that is used for the interrogator equipped with an appropriate input keyboard or a computer keyboard is. It is therefore possible for an operator to have the current configuration to call and control at the spinning station. The ad or Depending on requirements, polling can be advantageous either at each spinning position, centrally on the spinning machine, on a decentralized control for the Spinning machine, on a maintenance device, a central control for the spinning factory or externally in a service center.

The configuration can be particularly advantageous with the interrogation device call up every spinning position of a spinning machine and then use the Interrogator or an evaluation unit with others, from the spinning station correlate the data obtained. For example, the measured Quality values of the yarn produced correlated with the placement or the total life of a replaceable component is monitored, in order to carry out statistical quality analyzes from this data. Lie For example, the yarn values at a spinning station are more often outside of one Tolerance range, on the one hand it can be determined whether the configuration on interchangeable components at the spinning station for the desired Quality is suitable, or whether based on other experience gained the quality of the yarn is attributed to a special component can be.

In a control system according to claim 35, the so determined and evaluated data used by the spinning station to control parameters to optimize for the spinning machine or the spinning station and accordingly set optimized parameters on the spinning machine or spinning station. Based on the results obtained from quality assurance measures are actively taken to ensure the quality of the spun material Increase yarn further.

The display and / or interrogation device and the control system are not only usable for a spinning station of a spinning machine, but accordingly to record, control and control another spinning machine suitable in a spinning mill. Examples of such spinning machines with at least one interchangeable component are a card, one Draw frame or a ring spinning machine.

FIGS. 1A-E show partial cross sections through coatings on base bodies 100 of an interchangeable component. In the embodiment of 1A is the base body 100 in the desired area with a hard material layer 105 coated. Dyes 101 are embedded in the hard material layer 105. The dyes are either chemical elements or molecules, which lead to the emission of a certain wavelength of light. The Dyes 101 serve as impurities, so that the surrounding hard material layer areas Emit light or the dyes 101 emit themselves Irradiation with light. The irradiation with light is exemplified by the straight line Arrows shown as excitation light 102. The emission after the excitation is represented by the waved arrows as emission light 103.

In the embodiment of FIG. 1B, the base body 100 is first a luminous layer 104 is applied, on which a hard material layer 105 is then formed follows. The luminescent layer 104 contains the dyes 101 and emits light Excitation by the excitation light 102 Luminous layer 104 other functions, such as an adhesion promoter between the base body 100 and the hard material layer 105. Is the hard material layer 105 for the excitation light 102 or emission light 103 not or is not sufficiently transparent, the emission light 103 only then becomes detects when the hard material layer 105 is sufficiently thin or has already been removed has been. Consequently, when the emission light 103 is detected thereon can be concluded that the hard material layer 105 has been worn out.

1C shows an embodiment in which the coating is a combination of a matrix layer 106 and hard material particles 107 embedded therein. The hard material particles 107 contain dyes, so that when the hard material particles 107 are excited, light of the desired wavelength is emitted. As shown in Fig. 1A, the dyes can be incorporated as impurities into the hard material particles 108 so that these lights, or the dyes illuminate in the hard material particles 107 themselves. The former case is, for example incorporation of chromium or chromium oxide in Al ₂ O ₃ (sapphire) so that the known ruby red can be observed. FIG. 1D is a modification of FIG. 1C, in which the hard material particles 108 themselves do not shine, but instead the dyes 109 built into the matrix 106 or the matrix itself shines, as is described, for example, in relation to FIG. 1A.

In the embodiment of FIG. 1E, non-luminous hard material particles 108 and, in addition, luminous luminous particles 110 are installed in the matrix 106 of the coating. The luminous particles 110 are, for example, chromium or chromium oxide-doped Al ₂ O ₃ particles or porous silicon or another porous ceramic, which fluoresce when excited by UV light. 1A-1E, different luminous dyes 101, 109 or dyes in different constituents 105, 104, 106, 107, 108, 110 or in different forms are incorporated, so that at least two emission wavelengths are available. A coating of this type is thus color-coded, so that, for example, in addition to component or wear recognition, component type recognition is also made possible. Instead of or in addition to the hard material particles, friction-reducing particles can be provided, such as Teflon, graphite or MoS ₂ deposits in the matrix.

2A and 2B schematically show two embodiments of sensor units 115, 116. The sensor unit 115 of Fig. 2A is for immediate Arrangement provided on the surface to be detected 123, while the sensor unit 115 of FIG. 2B into a basic unit and a measuring head is divided, with the measuring head via optical fibers 125, 127 with the base unit connected is. In the sensor unit 115, the excitation light 102 generated by a laser diode or a light emitting diode 120. The light will focused by a lens 122 and as an excitation light 102 on the surface 123 directed. The emission light 103 also partially falls on an optical system 124, which is followed by a photodiode 125 for detecting the emission light is. The optics 124 comprise a combination of lens and color filter, so that on the one hand only the one illuminated by the excitation light 102 if possible Detected and selectively the emission wavelength by means of color filtering 103 is proven. The diode laser 120 is on a line 121 supplies and the photodiode 125 sends the signal over a line 126 to a downstream evaluation circuit. The line continues to see 126 a power supply for the photodiode, so that the emission light can prove even more sensitive.

FIG. 3 shows a partial cross-sectional view of a spinning station 1 of a rotor spinning machine and a partial side view of one of the spinning station 1 can be provided Robot 2. In the spinning box of the spinning station 1 is known per se Way a spinning rotor 3 rotatably supported and driven. At the front end a shaft 4 of the spinning rotor 3, a rotor plate 5 is attached. The open one The opposite side of the rotor plate 5 is in a cover 6 a thread take-off nozzle 7 is arranged in the spin box. On the outside of the Cover 6 connects to the thread take-off nozzle 7, a thread take-off tube 8 on.

During the thread production, the spun, dash-dotted in Figure 3 illustrated thread 9 from the groove 18a of the rotor plate 5 through the thread draw-off nozzle 7 and the thread withdrawal tube 8 is withdrawn. The piecing of the thread 9 is carried out in a manner known per se by means of the robot 2 and the thread 9 is after piecing over a pair of draw rollers wound on a continuously driven spool in a manner known per se (not shown).

In the thread take-off tube 8 is a disk-like from the top Twist stop insert 10 used, the wear with regard to abrasion by the pulled thread and which is a surface structuring has a desired number of turns per thread length. The passage of the thread take-off tube 8 is designed like a slot, the inlet slot adjacent to the thread take-off nozzle 7 Cross section of the bore in the thread take-off nozzle 7 corresponds and to the thread exit side increases upwards like a funnel. The free cross section the bore of the thread take-off nozzle 7 is therefore through the thread take-off tube 8 continued coaxially and expanded upwards. When pulling off of the thread 9, the thread lies on an arc segment of the swirl stop insert 10 on.

A movably mounted detector unit is arranged on the robot 2, that on request in a thread withdrawal tube 8 opposite Position is moved. An extendable is in the detector unit 11 Detector tube 12 mounted with a sensor head 12a, which is used to detect Markings can be extended from the housing of the detector unit 11. At the The tube 12 extends through the thread take-off tube 8 and Thread take-off nozzle 7 up to the vicinity of the rotor plate base 18.

Optical fibers run in the detector tube 12, which extend as far as the sensor head 12a of the tube 12 and there connected to the imaging system 13 are. An illumination source is arranged in the detector unit 11 Light through the optical fibers in the tube 12 to the imaging system 13 is guided and there from the imaging system, for example a lens element, exit. The light reflected from the object to be measured is in turn collected by the imaging system 13 and via the Optical fibers are coupled back into the detector unit 11, where it is from a optoelectronic sensor is detected. Contains the object to be measured Color marking, the detector unit 11 closes depending on the Illumination source, stray light and the spectral range of the object still a frequency band filter and spectrally resolving elements, for example as explained above for FIGS. 2A and 2B.

There is an optical marking on the inner surface of the swirl stop insert 10 15 in the form of a surface coating or coating with color elements (see e.g. Fig. 1A-1E) arranged (only shown symbolically in Fig. 3), by the imaging system 13 when passing through the thread take-off tube 8 is detected. Corresponding to the marking 15 is on the inside an optical marking 14 in the bore of the thread take-off nozzle 7 arranged, which is detected when entering the tube 12 in the spin box. As soon as the detector tube 12 is in its end position, an optical one Marking in the form of a coating or coating (e.g. Fig. 1A to 1E) specifically detected in the rotor groove 18a. The imaging system 13 focuses the excitation light 102 is directed into the groove 18a and also detects that Emission light 103 locally from there.

4A and 4B show two embodiments of arrangements for detection of optical markings in the form of a coating with color elements in or on a spinning rotor pot 5. The spinning station is similar to FIG the robot 2 is delivered for maintenance. In this case, the rotor cover folded down the spinning station and has an extension unit 104 inside the rotor plate 5 provided a cleaning head 141. The cleaning head 141 is motor-driven to clean the inside of the rotor. On the extension unit 140 there is a sensor unit 142 with an optical one Head 143 arranged. The head end of the optical head 143 is arranged and has near the cleaning brushes of the cleaning head 141 an optical element for focusing the excitation light in the direction Rotor groove 18a. The light emitted is also from the optical head 143 specifically received by the rotor groove 18a and evaluated in the sensor unit 142. The brushes are not evenly on the cleaning head 141 its outer circumference is distributed, but there are gaps between the bristles, so that there are gaps in the circumferential direction through which the Light from the optical head 143 to the rotor groove can be sent and received can.

In addition to the detection of wear and the identification of the rotor 3 can check the result of cleaning the rotor groove at the same time become. A missing emission signal indicates that either the Rotor with the special rotor groove coating is not installed, the wear layer in the rotor groove is worn or there is still contamination are in the rotor groove. The latter can be verified by the fact that the cleaning cycle with the cleaning head 141 is extended by the to achieve the desired cleaning effect. Should after long cleaning the emission light cannot be detected, so either is a stubborn one Contamination present, so that the rotor 3 must be serviced. Or the wear layer is worn, which also requires maintenance. Or the component is actually not provided with this special coating. For example, the rotor speed is reduced in the latter case, if special rotors are required for extremely high rotor speeds, or the spinning station is not spun on again for safety reasons.

FIG. 4B shows the arrangement of FIG. 4A with a modified sensor unit 142 'and a modified optical head 143'. In this case recorded the optical head 143 'is an optical marking in the form of the coating or surface coating on the outer circumference of the rotor pot 5 in the wall area 18b. Opposite wall 18b is an optical window on optical head 143 'is provided, through which the wall 18b is illuminated and through which the emitted light returns to the optical head 143 '. The sensor unit 142 'and the head 143' are advantageously mechanically stable trained so that in addition to the optical detection also by planting the optical head 143 'on the outer wall a rotation of the rotor 4 during cleaning with the cleaning head 141 is prevented.

FIG. 5 shows an optoelectronic detection system for optical detection of interchangeable components at a spinning position of a rotor spinning machine. For better clarity of the structure of the system are the reproduce individual elements only schematically. Arrangement and operation the elements of the rotor spinning machine is carried out in a manner known per se. 20 denotes a shaft of the spinning rotor, 21 an optical marking on the shaft 20, 22 an optical sensor head and 23 a signal line. 30 denotes a rotor plate, 31 an optical marking on the Rotor plate, 32 an optical sensor head for reading out the marking 31 and 33 a signal line. 40 denotes a support disc for storing the Rotor shafts 20, 41 have an optical marking on the support disk 40, 42 an optical sensor head and 43 a signal line. 50 denotes a Side part of an opening roller, 51 an optical marking on the side part, 52 an optical sensor head and 53 a signal line. All or at least Part of the markings 21, 31, 41, 51 are coatings here (e.g. Fig. 1A-1E) or coatings with specially embedded color elements to achieve this a desired, reproducible emission wavelength or - band. For example, 21 is a hard material layer on the rotor shaft in the Contact area of a driving tangential belt (not shown) or in the contact area of the support disk 40.

The sensor heads 22, 32, 42 and 52 and the signal lines 23, 33, 34, 53 are constructed identically. The sensor heads are either passive pickups for emitting and receiving light, which in this case is via optical fibers is transmitted as signal lines (such as in Fig. 2B). Or the sensor heads are active, optoelectronic components that themselves mark illuminate, absorb the reflected light and convert it into electrical signals (such as in Fig. 2A). The signal lines are electrical lines to transmit the measurement signals from the sensor heads and to provide them the power supply for the sensor heads.

A first embodiment of the signal processing is shown in FIG. 5 with "A" designated. In this case, the signal lines 23, 33, 43, 53 are in one optoelectronic or electronic multiplexer 60 merged and from this a signal is sent to a receiving and evaluation unit 61 forwarded. From there, the evaluated signals are sent via a Data channel 62 to a control unit 63 of the spinning station or the rotor spinning machine forwarded. The unit 61 can be in a section controller be integrated, so that data of a group of spinning stations section by section be recorded in one unit.

In a second embodiment ("B" in Figure 5) the signal lines 23, 33, 43, 53 in an optoelectronic or electronic multiplexer 70 merged and sequentially via a line to a transmitter unit 71 transferred. The transmission unit 71 transmits the multiplexed signal an optical path to the robot 2, which is provided with the spinning station 1. The robot 2 has a receiving unit 72 for receiving the optical one Signals from the transmitting unit 71 and transmits the received signals to Control unit 73 of the robot 2.

This is the configuration and / or status data can be called up on a display device of the control unit 87. Of the central controller 87 can also transmit the data via a communication bus 84 are transferred to the robot 85.

From the control unit 87 of the spinning machine, the data is about one Communication bus 90 transferable to a factory control system 91, where it can also be called up on a display device 92. Are dash-dotted further control units for spinning machines 87a, 87b and communication buses 90a, 90b, which are also connected to the factory control system 91 are.

The control unit of the spinning machine 87 or the factory control system 91 are via communication lines 97, 98 with a data transmission unit 93 connected. The data from the data transfer unit 93 are received by an external data transmission unit 94 and sent to a Service unit 95 transmitted. The data is there via a display device 96 available.

Based on the configuration and / or status data available, the operating and quality parameters can then be in one of the Control units 85, 87, 91, 95 optimized operating parameters for operation at the spinning station 80 and calculate these optimization parameters via the Communication channels 84, 88, 90, 97, 98, 93, 94 back to the spinning station control 80 transferred. For example, the optimization parameters transmitted from the service unit 95 to the external data transmission unit 94. Or the data becomes from the service unit 95 to the data transmission unit 93 transmitted and either entered into the factory control system 91 or passed on directly to the control unit 87 of the spinning machine.

The control and maintenance work is simplified, if the respective for the configuration and / or status data Spinning station number is recorded, so that an assignment and localization is possible. If the time of recording continues to be recorded, so can for example be an assembly and / or wear chronology create.

It can be used to implement a remote diagnosis system in which, due to the an available external evaluation in order to determine the cause of the error in the service center to be able to. If there are problems at the spinning position, it is therefore not necessary in any case that a service technician immediately Record the system configuration and perform analyzes on site.
