Definitions
- the invention relates to a yarn feeding device for textile machines, in particular knitting machines, such as circular knitting machines, flat knitting machines or others.
- Such yarn feeding devices are usually used to control the individual knitting a knitting machine, such as a circular knitting machine to supply a thread.
- Such yarn feeding devices are for example in the DE 199 32 481 A1 and the US 5,323,625 described.
- the DE 199 32 481 A1 relates to a yarn feeding device with a housing, which itself has a fastening device.
- the housing is provided with a parting line, wherein the housing parts are each provided with a bearing seat for a ball bearing for supporting a shaft.
- alignment means are provided for the correct arrangement of the two housing parts.
- the US 5,323,625 relates to a yarn feeding device provided with a yarn tension control.
- the yarn feeding device has a carrier designed as a housing on, which is provided at one end with a mounting clamp for attachment of the yarn feeding device to the knitting machine. This is for this purpose provided with an annular support - a so-called machine ring - on which sit many mutually substantially identical yarn feeding devices extending radially away from him.
- the carrier of the yarn feeding device has a lower arm and an upper arm, which define a gap between each other.
- the lower and the upper arm each carry a ball bearing for supporting a vertical shaft which carries at its lower end below the lower arm a yarn feed wheel.
- Pulleys for driving the shaft are provided both in the space between the two bearings and above the upper bearing. They can be coupled to the shaft via clutch discs. Circulating belts drive the pulleys, which ultimately causes the yarn feed wheel to rotate.
- the housing switching elements On the support or housing yarn feeler lever are pivotally mounted, operate the arranged inside the housing switching elements. These serve to signal a yarn breakage by means of a signal lamp which is attached to the housing.
- the signal lamp is arranged between the mounting clamp and the yarn feed wheel. If a viewer looks in the direction of the housing longitudinal direction on the yarn feeding device, he does not see the signal lamp. This line of sight is the natural line of vision, radial to the circular knitting machine for a viewer standing next to the knitting machine.
- the yarn feeding device is subject to contamination.
- filaments that are loosened from the entangled thread or the fabric are released to accumulate the air in knitwear with dust, which settles on all up-facing surfaces.
- dust deposits lead in the long term to unpleasant phenomena to functional impairments or loss of function. It is to be remedied.
- the DD-PS 207 940 discloses a yarn feeding device in the form of a belt conveyor. This has a cylindrical housing with a storage for a arranged below the housing Fadenunterrad. This is designed in the manner of a toothed disk over which the drive belt provided on the knitting machine runs to drive all yarn feeding devices. The thread is passed through thread guide elements between the drive belt and the toothed pulley, whereby it is conveyed.
- yarn feeding wheels can be used, which are set up, for example, for slippage-promoting the thread.
- Such yarn feed wheels are DE 10 219 537 A1 refer to.
- the yarn speed of the speed of the yarn feed wheel is no longer proportional.
- yarn feed wheels with active thread feed for example, according to DE 31 05 990 A1 come into use.
- the drive of the yarn feed wheel is preferably carried out at a given speed, which is constant in stationary operation, for example.
- the speed can be adjusted to the working speed of the knitting machine (speed of the circular knitting machine) be set proportionally.
- the serving for driving the yarn feed wheel at least one pulley is disposed in the space between the two legs. These carry the shaft bearings, which are preferably designed as ball bearings or otherwise rolling bearings.
- a housing which defines an interior space. This serves to receive one or more electrical or electronic components, e.g. can serve to monitor the operation of the yarn feeding device.
- the limited between the pulley and the yarn feed space is largely protected from dust. Due to its shielding effect, the pulley already prevents the pulley from stalling on the upper side and even more so when it is turning.
- the housing prevents; by occupying the space between the lower pulley and the yarn feed wheel, a deposit of Flus on the top of the yarn feed wheel or in the yarn feed wheel. The latter would be particularly annoying if the yarn feed wheel, as is preferred, is designed as a closed deep-drawn part without ventilation openings, which surrounds an interior like a pot.
- the support may, if necessary, be made relatively narrow so as to minimize the dust deposits that are thereon due to their distance from the moving parts and the thread still to minimize.
- the housing and the carrier are not necessarily but preferably formed as separate parts which are connected by suitable connecting means during assembly of the yarn feeding device. They can be made of different materials. While the carrier may be formed, for example, as a mechanically stable plastic or metal part, the housing does not have to take over a holding or carrying function and can be designed correspondingly thin-walled. It may have a different color than the carrier. This not only has an aesthetic effect but also structures the visual appearance of the machine ring with the yarn feeding devices.
- a different choice of material between the housing and the carrier also makes it possible to form the housing in whole or in part from a translucent, such as translucent or transparent material. In this way, on the one hand housed in the housing electronics is visible. This can serve to check the function, for example if there are securing elements or other optically controllable elements in the housing.
- optical signal elements for example light-emitting diodes or other communication elements, can be arranged directly on a printed circuit board arranged in the housing, which are visible on all sides through the housing, for example on all sides.
- the housing may also have photoconductive properties to aid in the overall visibility of the signal elements.
- a signal lamp arranged between the clamp and the yarn feeding wheel can thereby be replaced. Visibility is improved.
- one or more antennas for transmitting and / or receiving RF signals can be arranged.
- the cross section of the housing is somewhat smaller than the maximum cross section of the belt pulley and optionally slightly larger than the upper edge of the yarn feed wheel.
- the diameter of the pulley, housing and yarn delivery wheel then decrease in the order from top to bottom.
- the yarn feeler (inlet stop and outlet stop) are arranged completely below the device or carrier body.
- the yarn feelers thus do not project laterally under the carrier body. They also do not stand off to the side. By eliminating laterally projecting to the Abstellern belonging bracket the deposition of river is difficult.
- the devices are very narrow. If they are mounted close to each other on a machine ring, good access to the equipment is nevertheless granted. During maintenance and cleaning work, there are no disturbing wires or other parts standing sideways out of the devices.
- FIG. 1 is a yarn feeding device 1 illustrated, which is used for yarn delivery on a knitting machine, such as a circular knitting machine.
- a knitting machine such as a circular knitting machine.
- the yarn feeding device 1 has a carrier 3, which is provided for attachment to the machine ring 2 with a clamp 4.
- the support 4 is, for example, a metal part, for example an aluminum die-cast part, a zinc die-cast part or else a plastic injection-molded part or die-cast part.
- the clamp 4 has a downwardly open opening for receiving the machine ring and a clamping screw 5 to tighten the machine ring 4 in the opening.
- the carrier 3 extends to a first upper bearing device 6 and a second lower bearing device 7.
- the carrier as in FIG. 1 illustrated, for example, two straight or arcuate legs 8, 9 have, between which a gap 10 is limited.
- bearings 11, 12 are provided in the form of ball bearings coaxial with a common axis of rotation 13 on the bearing means 6 and 7 respectively. They serve to rotatably support a shaft 14, which carries a yarn feed wheel 15 at its lower end below the lower leg 9.
- a shaft 14 which carries a yarn feed wheel 15 at its lower end below the lower leg 9.
- the intermediate space 10 at least one, preferably a plurality of pulleys 16, 17 are arranged, which sit on the shaft 14 in order to drive them.
- an axially displaceable clutch disc 18 or other coupling means is provided for the rotationally fixed coupling of the pulley 16 or 17 to the shaft 14 .
- the yarn feed wheel 15 is at the lower end of the shaft 14 secured by a clamping screw 19 which is screwed into an axial end-side threaded bore of the shaft end.
- the clamping screw 19 is identical to the clamping screw 5 in order to support a simple and clear handling of the yarn feeding device 1.
- the bearing device 7 is part of the lower leg 9, which may extend into the interior of the pulley 16 in.
- the pulley 16 is still arranged in a distance between the space formed between the bearing device 7 and the bearing device 6, although it, at least partially, also overlaps the lower bearing means 7.
- the bearing device 7 is preferably part of the lower leg 9 of the carrier 3.
- This leg 9 extends from the terminal 4 to an end 20 on which a yarn brake 21 may be arranged.
- This can be designed according to any known type. For example, it may have magnetically adhering rings between which a thread 22 must pass.
- an inlet eye 23 serve, which is arranged at the free end of the upper leg 8. This extends, for example, from the terminal 4 first to the bearing device 6 and from this to its free end 24.
- a node catcher 25 may be arranged in the form of a slotted sheet, through the slot of the thread 22 runs. Between the account catcher 25 and the thread brake 21, a distance is formed, which grants free access to the pulley 16.
- the lower leg 9 preferably carries in the presented embodiment, a housing 26 which is arranged in the gap formed between the lower pulley 16 and the yarn feed wheel 15. If the diameters of the yarn feed wheel 15 and the pulley 16 coincide with each other, this gap is cylindrical. If the diameter of the yarn feed wheel 15 is smaller than that of the pulley 16, the gap is slightly conically tapered downwards. Regardless, the shape of the housing 26 is preferably set so that the gap is substantially filled. As can be seen, the diameter to be measured transversely to the leg 9 (measuring direction in FIG FIG. 1 perpendicular to the drawing plane) of pulley 16, housing 26 and yarn feed wheel 15 stepped from top to bottom.
- the pulley 16 has at its lower edge a largest diameter which is slightly larger than the diameter of the housing 26. This in turn preferably has a diameter which is at least slightly larger than the diameter of the upper edge of the yarn feed wheel 15 to this to take something over.
- the housing 26 is cylindrical made of a translucent or transparent plastic. At its top it is closed and it is supported by the carrier 3, in particular its leg 9. It also has a bottom 27 made of FIG. 2 can be seen. Approximately in the middle of a tubular extension 28 may be provided in the housing. This may be part of the holder 3 or part of the housing 26 or a separate part. Between the tube extension 28 and the housing 26, an annular interior 29 is defined, which surrounds the tube extension 28 and thus also the shaft 14.
- the housing 26 is not necessarily - but advantageously formed dense, so that it closes the interior 29 dust-tight against the environment.
- the bottom 27 may be slightly offset upwardly against the lower edge 30 of the outer shell of the housing 26 and thus, as seen from below, define a shallow recess into which the yarn feed wheel 15 protrudes somewhat into it.
- the latter is preferably formed as a sheet deep-drawn part in one piece. It has, for example, starting from an upper edge a conically steeply downwardly tapering inlet region 31 with circular cross-section, a ribbed storage area 32 with non-circular cross-section, which tapers slightly towards the bottom, and a flared lower edge region 33, over which the thread 22nd grazing runs off.
- the storage section 32 serves to receive a yarn winding 34, which is continuously moved slightly axially forward by the yarn running over the inlet region 31.
- the yarn delivery wheel 15 is preferably formed substantially hollow. Down it is completed with a closed end wall. The enclosed by the yarn feed wheel 15 interior is effectively protected by the bottom 27 and the cross over him edge 30 against flow entry.
- the components 35 to 40 include, for example, magnetically actuatable protective tube relays 35, 37 electronic circuits 36, light-emitting diodes 39 or other optical display means, one or more Antennas 40 and passive components, such as the resistor 38. Other components, such as fuses, capacitors, transistors, diodes and the like may occur.
- the circuit board 41 is provided for mounting in the annular interior 29 and has a corresponding cutout for the tube extension 28. It may also have an extension 42 which may extend out of the cylindrical portion of the housing 26 into another protected portion 43. This may be part of the housing 26 or may be formed by a suitable other cover.
- the protective tube contact relays 35, 37 are provided, for example, for detecting the tightness or slack or absence of the thread 22.
- an inlet sensor 44 and an outlet sensor 45 serve, which carry at their ends eyelets through which the thread 22 runs. If the thread is missing or hanging, it suspends the thread sensors 44, 45 from the positions shown in the figures in a suitable direction, thereby moving magnets, such as a permanent magnet 46, away from the respective protective tube contact relay. This can be brought to the display immediately or after a reasonable delay time selected by means of the LEDs 39.
- the thread brake (preferably without any eyelet) is preferably the only element touching the thread.
- the carrier 3 also, for example, in the immediate vicinity of the outlet sensor 45 thread guide eyes 47, 48 which determine the angle at which the thread 22 leaves the yarn feed wheel 15.
- the yarn feeding device 1 described so far operates on the principle of a positive guide. If a not further illustrated belt on the pulley 16 or 17, the yarn feed wheel 15 is rotated, this winds the thread 22 constantly. This runs over the inlet region 31 on the storage section 32.
- the yarn feed wheel 15 are the thread with a defined yarn speed on the outlet eyelets 47, 48 from.
- the inlet sensor 44 and the outlet sensor 45 are in their working positions.
- the electronic circuit on the circuit board 41 detects this and the LEDs 39 do not light up.
- Flus may possibly deposit on the carrier 3, but not on the housing 26 arranged between the pulley 16 and the yarn feed wheel 15. Despite its relatively large volume and spacious interior, it remains clean on the outside. Its in the case of an example transparent outsides remain clean. The interior lighting elements remain visible from all sides.
- the holder like FIG. 4 illustrated, between its legs 8, 9 have a stiffener in the form of a web 49. Between the web 49 and the terminal 4, a recess 50 may be provided. This can be formed as a passage opening or closed by a thin wall. The latter is especially useful in the production of the carrier 3 from a low-cost plastic.
- the housing 26 deviate from the cylindrical shape. It may, for example, be prismatic, ie have a polygonal cross-section.
- FIG. 4 shows corresponding edges 51, 52, 53, 54 of the hexagonal in the example housing 26. It may also have an octagonal or otherwise shaped cross-section.
- the division may relate, for example, to the lower leg 9, one part of which extends from the clamp 4 to the bearing device 7.
- Another part 55 may extend on the one hand to the end 20 and on the other hand be formed as a housing to receive the extension 42 of the circuit board 41 and the outlet sensor 45 and the outlet eyelet 47, 48 to wear.
- the part 55 is connected to the leg with respect to the rotation axis 13 non-rotatably.
- it may have a lower conically flared edge 56 which engages over the upper edge of the yarn feed wheel 15 somewhat and protects it and its interior against flow.
- FIG. 5 shows the shaft 14 extend beyond the upper bearing means 6 to one or more other pulleys or even a motor to wear.
- the Auslaufstellsteller formed from the outlet sensor 45 and the outlet eyelets 47, 48 together with other elements is an assembly that can be removed from the yarn feeding device without releasing it from the machine ring.
- the new yarn feeding device 1 is therefore particularly easy to maintain.
- FIG. 6 illustrates a modified embodiment of the inlet sensor 44 schematically.
- the inlet sensor 44 is arranged pivotable about a horizontal axis of rotation 57.
- the protective tube contact switch 37 is arranged as a magnetic sensor.
- a permanent magnet 58 is fixedly installed in the vicinity thereof.
- the inlet sensor 44 is connected to a shield plate 59, which stands at taut thread 22 in the space between the permanent magnet 58 and the Schutzrohrkomschalter 37. It shields the magnetic field of the permanent magnet from the protective tube contact switch 37. He is open, ie does not conduct electricity.
- the run-in sensor pivots to a different position, whereby the shielding plate 59 is moved out of the gap between the permanent magnet 58 and the protective tube contact switch 37.
- the magnetic field of the permanent magnet 58 now reaches the protective tube contact switch 37. Its contacts close, a current can flow.
- the same principle can be applied to the spout sensor 45.
- the yarn feeding device has a carrier 3, which connects its storage facilities 6, 7 with a terminal 4. Between the bearing devices 6, 7, at least one pulley 16 is provided for driving a vertical shaft 14 supported by the bearing devices 6, 7, which carries a yarn feed wheel at its lower end. Between the lower pulley 16 and the yarn feed wheel 15, a housing 26 is provided, which is held by the carrier 3 and serves to accommodate an electrical or electronic circuit. The housing is housed in a river protected area and can be made relatively large and voluminous.

Description
Die Erfindung betrifft ein Fadenliefergerät für Textilmaschinen, insbesondere Strickmaschinen, wie beispielsweise Rundstrickmaschinen, Flachstrickmaschinen oder sonstige.The invention relates to a yarn feeding device for textile machines, in particular knitting machines, such as circular knitting machines, flat knitting machines or others.
Solche Fadenliefergeräte werden in der Regel dazu verwendet, den einzelnen Strickstellen einer Strickmaschine, beispielsweise einer Rundstrickmaschine, einen Faden kontrolliert zuzuführen.Such yarn feeding devices are usually used to control the individual knitting a knitting machine, such as a circular knitting machine to supply a thread.

An dem Träger bzw. Gehäuse sind Fadenfühlhebel schwenkbar gelagert, die im Inneren des Gehäuses angeordnete Schaltelemente betätigen. Diese dienen zur Signalisierung eines Fadenbruchs mittels einer Signallampe, die an dem Gehäuse angebracht ist. Die Signallampe ist dabei zwischen der Befestigungsklemme und dem Fadenlieferrad angeordnet. Schaut ein Betrachter mit Blickrichtung in Gehäuselängsrichtung auf das Fadenliefergerät sieht er die Signallampe nicht. Diese Blickrichtung ist die natürliche Blickrichtung, radial zur Rundstrickmaschine für einen neben der Strickmaschine stehenden Betrachter.On the support or housing yarn feeler lever are pivotally mounted, operate the arranged inside the housing switching elements. These serve to signal a yarn breakage by means of a signal lamp which is attached to the housing. The signal lamp is arranged between the mounting clamp and the yarn feed wheel. If a viewer looks in the direction of the housing longitudinal direction on the yarn feeding device, he does not see the signal lamp. This line of sight is the natural line of vision, radial to the circular knitting machine for a viewer standing next to the knitting machine.
Im praktischen Einsatz unterliegt das Fadenliefergerät der Verschmutzung. Während des Strickvorgangs lösen sich aus dem verstrickten Faden bzw. dem Gestrick Filamente, die die Luft in Strickereien mit Staub anreichern, der sich auf allen nach oben weisenden Flächen ablagert. Solche Staubablagerungen führen auf Dauer zu unangenehmen Erscheinungen bis hin zu Funktionsbeeinträchtigungen oder Funktionsverlust. Dem gilt es abzuhelfen.In practical use, the yarn feeding device is subject to contamination. During the knitting process, filaments that are loosened from the entangled thread or the fabric are released to accumulate the air in knitwear with dust, which settles on all up-facing surfaces. Such dust deposits lead in the long term to unpleasant phenomena to functional impairments or loss of function. It is to be remedied.
Die
An der Oberseite des zylindrischen Gehäuses kann sich Flus ablagern.At the top of the cylindrical housing flow can settle.
Es ist Aufgabe der Erfindung, Fadenliefergeräte hinsichtlich einer oder mehrerer der oben genannten Eigenarten weiter zu entwickeln bzw. Nachteilen abzuhelfen.It is an object of the invention to further develop yarn feeding devices with respect to one or more of the above peculiarities or to remedy disadvantages.
Diese Aufgabe wird mit dem Fadenliefergerät nach Anspruch 1 gelöst:
- Das erfindungsgemäße Fadenliefergerät weist einen Träger auf, der an einem Ende eine Klemme zur Befestigung des Fadenliefergeräts an der Textilmaschine aufweist. Der Träger hält zwei Kugellager vertikal übereinander fluchtend auf Abstand. Die Kugellager lagern eine vertikal angeordnete Welle drehbar, die an ihrem unteren Ende mit einem Fadenlieferrad versehen ist. Das Fadenlieferrad ist vorzugsweise zur Positiv-Fadenlieferung eingerichtet. Diese liegt vor, wenn ein Faden schlupffrei gefördert wird. Dazu umschlingt der Faden das Fadenlieferrad mehrmals, um einen Wickel zu bilden. Der Faden läuft streifend über den oberen vorzugsweise konischen Rand des Fadenlieferrads, wenn sich dieses dreht. Er bildet dann auf dem Speicherbereich einen Wickel und läuft dann vorzugsweise über den unteren Rand des Fadenlieferrads streifend ab. Die Drehzahl des Fadenlieferrads ist der Fadenlaufgeschwindigkeit proportional. Solche Fadenlieferräder können als einstückige Blech-Tiefziehteile, als Keramikkörper, als Drehteile, als Stabkäfige oder auf sonstige, aus dem Stand der Technik bekannte Weise ausgebildet sein. Sie können aus einem oder mehreren Teilen bestehen. Vorzugsweise sind sie an dem unteren Wellenende auswechselbar gehalten. Die Befestigung erfolgt vorzugsweise mittels einer axialen Befestigungsschraube, die zu der Klemmschraube, der an dem Halter vorgesehenen Klemme identisch ist. Die Schrauben sind dadurch austauschbar.
- The yarn feeding device according to the invention has a carrier which has at one end a clamp for fastening the yarn feeding device to the textile machine. The carrier holds two ball bearings vertically one above the other at a distance. The ball bearings rotatably support a vertically arranged shaft, which is provided at its lower end with a yarn feed wheel. The yarn feed wheel is preferably set up for positive thread delivery. This occurs when a thread is conveyed slip-free. For this purpose, the thread wraps around the thread delivery wheel several times to form a roll. The thread runs grazing over the upper, preferably conical edge of the Fadenlieferrads when it rotates. He then forms a winding on the storage area and then preferably runs over the lower edge of the Fadenlieferrads grazing. The speed of the yarn feed wheel is proportional to the yarn running speed. Such yarn feed wheels may be formed as one-piece sheet-deep-drawn parts, as a ceramic body, as turned parts, as rod cages or other, known from the prior art manner. They can consist of one or more parts. Preferably, they are kept interchangeable at the lower end of the shaft. The fastening preferably takes place by means of an axial fastening screw, which is identical to the clamping screw, the clamp provided on the holder. The screws are therefore interchangeable.
Alternativ können andere Fadenlieferräder Anwendung finden, die beispielsweise zur schlupfbehafteten Förderung des Fadens eingerichtet sind. Solche Fadenlieferräder sind der
Der Antrieb des Fadenlieferrads erfolgt vorzugsweise mit gegebener Drehzahl, die im stationären Betrieb beispielsweise konstant ist. Die Drehzahl kann zu der Arbeitsgeschwindigkeit der Strickmaschine (Drehzahl der Rund-Strickmaschine) proportional festgelegt sein. Die zum Antrieb des Fadenlieferrads dienende, zumindest eine Riemenscheibe ist in dem Zwischenraum zwischen den beiden Schenkeln angeordnet. Diese tragen die Wellenlager, die vorzugsweise als Kugellager oder auch anderweitige Wälzlager ausgebildet sind.The drive of the yarn feed wheel is preferably carried out at a given speed, which is constant in stationary operation, for example. The speed can be adjusted to the working speed of the knitting machine (speed of the circular knitting machine) be set proportionally. The serving for driving the yarn feed wheel, at least one pulley is disposed in the space between the two legs. These carry the shaft bearings, which are preferably designed as ball bearings or otherwise rolling bearings.
In dem Raum zwischen der zu unterst angeordneten Riemenscheibe und dem Fadenlieferrad und vorzugsweise unterhalb des unteren Lagers ist ein Gehäuse vorgesehen, das einen Innenraum umgrenzt. Dieser dient der Aufnahme einer oder mehrerer elektrischer oder auch elektronischer Bauelemente, die z.B. dazu dienen können, den Betrieb des Fadenliefergeräts zu überwachen. Der zwischen der Riemenscheibe und dem Fadenlieferrad begrenzte Raum ist vor Staubfall weitgehend geschützt. Oberseitig verhindert die Riemenscheibe aufgrund ihrer Schirmwirkung schon im Stillstand und erst recht, wenn sie sich dreht, eine Flusablagerung. Andererseits verhindert das Gehäuse; indem es den Raum zwischen der unteren Riemenscheibe und dem Fadenlieferrad einnimmt, eine Ablagerung von Flus auf der Oberseite des Fadenlieferrads bzw. in dem Fadenlieferrad. Letzteres wäre insbesondere lästig, wenn das Fadenlieferrad, wie es bevorzugt wird, als geschlossenes Tiefziehteil ohne Lüftungsöffnungen ausgebildet ist, das wie ein Topf einen Innenraum umschließt.In the space between the bottom pulley arranged and the yarn feed wheel and preferably below the lower bearing, a housing is provided which defines an interior space. This serves to receive one or more electrical or electronic components, e.g. can serve to monitor the operation of the yarn feeding device. The limited between the pulley and the yarn feed space is largely protected from dust. Due to its shielding effect, the pulley already prevents the pulley from stalling on the upper side and even more so when it is turning. On the other hand, the housing prevents; by occupying the space between the lower pulley and the yarn feed wheel, a deposit of Flus on the top of the yarn feed wheel or in the yarn feed wheel. The latter would be particularly annoying if the yarn feed wheel, as is preferred, is designed as a closed deep-drawn part without ventilation openings, which surrounds an interior like a pot.
Andererseits wird reichlich Aufnahmeraum für einfache oder auch umfangreichere Schaltungen geboten. Dies ohne das Gehäuse der Gefahr von Staubablagerungen auszusetzen. Der Träger kann bedarfsweise relativ schmal ausgeführt werden, um die darauf vorzufindenden, aufgrund ihrer Ferne zu den bewegten Teilen und zum Faden eher harmlosen Staubablagerungen noch zu minimieren.On the other hand, ample recording space for simple or more extensive circuits is offered. This without exposing the housing to the risk of dust deposits. The support may, if necessary, be made relatively narrow so as to minimize the dust deposits that are thereon due to their distance from the moving parts and the thread still to minimize.
Das Gehäuse und der Träger sind nicht zwingend aber vorzugsweise als gesonderte Teile ausgebildet, die durch geeignete Verbindungsmittel beim Zusammenbau des Fadenliefergeräts miteinander verbunden werden. Sie können aus unterschiedlichen Materialien ausgebildet sein. Während der Träger beispielsweise als mechanisch stabiles Kunststoff- oder Metallteil ausgebildet sein kann, muss das Gehäuse keine Halte- oder Tragefunktion übernehmen und kann entsprechend dünnwandig ausgebildet sein. Es kann eine andere Farbe aufweisen wie der Träger. Dies hat nicht nur ästhetische Wirkung sondern strukturiert das optische Erscheinungsbild des Maschinenrings mit den Fadenliefergeräten.The housing and the carrier are not necessarily but preferably formed as separate parts which are connected by suitable connecting means during assembly of the yarn feeding device. They can be made of different materials. While the carrier may be formed, for example, as a mechanically stable plastic or metal part, the housing does not have to take over a holding or carrying function and can be designed correspondingly thin-walled. It may have a different color than the carrier. This not only has an aesthetic effect but also structures the visual appearance of the machine ring with the yarn feeding devices.
Eine unterschiedliche Materialwahl zwischen Gehäuse und Träger gestattet es auch, das Gehäuse ganz oder teilweise aus einem lichtdurchlässigen, beispielsweise durchscheinenden oder durchsichtigen Material auszubilden. Auf diese Weise ist einerseits die in dem Gehäuse untergebrachte Elektronik sichtbar. Dies kann der Funktionskontrolle dienen, beispielsweise wenn sich in dem Gehäuse Sicherungselemente oder sonstige optisch auf Funktion kontrollierbare Elemente befinden. Des Weiteren können unmittelbar auf einer in dem Gehäuse angeordneten Leiterplatte optische Signalelemente, beispielsweise Leuchtdioden oder sonstige Kommunikationselemente angeordnet sein, die durch das Gehäuse hindurch nach mehreren Seiten z.B. allseitig sichtbar sind. Das Gehäuse kann außerdem lichtleitende Eigenschaften aufweisen, um die allseitige Sichtbarkeit der Signalelemente zu unterstützen. Eine zwischen der Klemme und dem Fadenlieferrad angeordnete Signallampe kann dadurch ersetzt werden. Die Sichtbarkeit wird verbessert. In dem Gehäuse können auch ein oder mehrere Antennen zum Senden und/oder empfangen von HF-Signalen angeordnet sein.A different choice of material between the housing and the carrier also makes it possible to form the housing in whole or in part from a translucent, such as translucent or transparent material. In this way, on the one hand housed in the housing electronics is visible. This can serve to check the function, for example if there are securing elements or other optically controllable elements in the housing. Furthermore, optical signal elements, for example light-emitting diodes or other communication elements, can be arranged directly on a printed circuit board arranged in the housing, which are visible on all sides through the housing, for example on all sides. The housing may also have photoconductive properties to aid in the overall visibility of the signal elements. A signal lamp arranged between the clamp and the yarn feeding wheel can thereby be replaced. Visibility is improved. In the case can also one or more antennas for transmitting and / or receiving RF signals can be arranged.
Die gesonderte Ausbildung von Gehäuse und Träger und die Entkleidung des Gehäuses von jeglicher Tragfunktion ermöglicht es, dieses besonders dünnwandig auszulegen. Somit können Schaltelemente, wie beispielsweise magnetisch zu schaltende Schutzrohrschalter oder ähnliches, in dem Gehäuse untergebracht und problemlos durch außen angeordnete Magnete betätigt werden.The separate design of housing and carrier and the lining of the housing of any support function makes it possible to design this particularly thin-walled. Thus, switching elements, such as magnetically switched protective tube switch or the like, housed in the housing and easily operated by externally arranged magnets.
Hinsichtlich der eingangs besprochenen Staubablagerungen ist es vorteilhaft, wenn der Querschnitt des Gehäuses etwas geringer als der Maximalquerschnitt der Riemenscheibe und gegebenenfalls etwas größer als der obere Rand des Fadenlieferrads ist. Die Durchmesser von Riemenscheibe, Gehäuse und Fadenlieferrad nehmen dann in der genannten Reihenfolge von oben nach unten ab.With regard to the dust deposits discussed at the outset, it is advantageous if the cross section of the housing is somewhat smaller than the maximum cross section of the belt pulley and optionally slightly larger than the upper edge of the yarn feed wheel. The diameter of the pulley, housing and yarn delivery wheel then decrease in the order from top to bottom.
Vorzugsweise sind die Fadenfühler (Einlaufabsteller und Auslaufabsteller) vollständig unterhalb des Geräte- bzw. Trägerkörpers angeordnet. Die Fadenfühler ragen somit nicht seitlich unter dem Trägerkörper hervor. Sie stehen auch nicht seitlich ab. Durch den Wegfall seitlich abstehender zu den Abstellern gehöriger Bügel wird die Ablagerung von Flus erschwert. Außerdem bauen die Geräte sehr schmal. Sind sie auf einem Maschinenring dicht nebeneinander montiert, wird dennoch guter Zugang zu den Geräten gewährt. Bei Wartung- und Reinigungsarbeiten stören keine seitlich aus den Geräten stehenden Drähte oder sonstigen Teile.Preferably, the yarn feeler (inlet stop and outlet stop) are arranged completely below the device or carrier body. The yarn feelers thus do not project laterally under the carrier body. They also do not stand off to the side. By eliminating laterally projecting to the Abstellern belonging bracket the deposition of river is difficult. In addition, the devices are very narrow. If they are mounted close to each other on a machine ring, good access to the equipment is nevertheless granted. During maintenance and cleaning work, there are no disturbing wires or other parts standing sideways out of the devices.

Das Fadenlieferrad 15 ist an dem unteren Ende der Welle 14 mittels einer Klemmschraube 19 befestigt, die in eine axiale stirnseitige Gewindebohrung des Wellenendes eingeschraubt ist. Vorzugsweise ist die Klemmschraube 19 mit der Klemmschraube 5 identisch, um eine einfache und einleuchtende Handhabung des Fadenliefergeräts 1 zu unterstützen.The
Die Lagereinrichtung 7 ist Teil des unteren Schenkels 9, die sich in den Innenraum der Riemenscheibe 16 hinein erstrecken kann. Die Riemenscheibe 16 ist dennoch insoweit in einem zwischen der Lagereinrichtung 7 und der Lagereinrichtung 6 gebildeten Abstand oder Zwischenraum angeordnet, obwohl sie, zumindest teilweise, auch die untere Lagereinrichtung 7 übergreift.The
Die Lagereinrichtung 7 ist vorzugsweise Teil des unteren Schenkels 9 des Trägers 3. Dieser Schenkel 9 erstreckt sich von der Klemme 4 zu einem Ende 20, an dem eine Fadenbremse 21 angeordnet sein kann. Diese kann nach jeder bekannten Bauart ausgebildet sein. Beispielsweise kann sie magnetisch aneinander haftende Ringe aufweisen, zwischen denen ein Faden 22 hindurch laufen muss.The
Zur Führung des Fadens 22 auf seinem Weg zu der Fadenbremse 21 kann eine Einlauföse 23 dienen, die an dem freien Ende des oberen Schenkels 8 angeordnet ist. Dieser erstreckt sich z.B. von der Klemme 4 zunächst zu der Lagereinrichtung 6 und von dieser zu seinem freien Ende 24. Unterhalb der Einlauföse 23 kann ein Knotenfänger 25 in Form eines geschlitzten Blechs angeordnet sein, durch dessen Schlitz der Faden 22 läuft. Zwischen dem Kontenfänger 25 und der Fadenbremse 21 ist ein Abstand ausgebildet, der freien Zugang zu der Riemenscheibe 16 gewährt.To guide the
Der untere Schenkel 9 trägt bei der vorgestellten Ausführungsform vorzugsweise ein Gehäuse 26, das in dem zwischen der unteren Riemenscheibe 16 und dem Fadenlieferrad 15 ausgebildeten Zwischenraum angeordnet ist. Stimmen die Durchmesser von dem Fadenlieferrad 15 und der Riemenscheibe 16 miteinander überein, ist dieser Zwischenraum zylindrisch. Ist der Durchmesser des Fadenlieferrads 15 kleiner als derjenige der Riemenscheibe 16 ist der Zwischenraum sich nach unten verjüngend leicht konisch. Unabhängig davon ist die Form des Gehäuses 26 vorzugsweise so festgelegt, dass der Zwischenraum im Wesentlichen ausgefüllt wird. Wie ersichtlich, ist dabei insbesondere der quer zu dem Schenkel 9 zu messende Durchmesser (Messrichtung in
Das Gehäuse 26 ist nicht unbedingt - aber doch vorteilhafterweise dicht ausgebildet, so dass es den Innenraum 29 gegen die Umgebung staubdicht abschließt.The
Der Boden 27 kann gegen den unteren Rand 30 des äußeren Mantels des Gehäuses 26 etwas nach oben versetzt sein und somit von unten gesehen eine flache Ausnehmung begrenzen, in die das Fadenlieferrad 15 etwas hinein ragt.The bottom 27 may be slightly offset upwardly against the
Letzteres ist vorzugsweise als Blechtiefziehteil einstückig ausgebildet. Es weist beispielsweise ausgehend von einer oberen Kante einen sich konisch steil nach unten verjüngenden Einlaufbereich 31 mit Kreisquerschnitt, einen gerippten Speicherbereich 32 mit unrundem Querschnitt, der sich nach unten hin nur wenig verjüngt, und einen ausgestellten unteren Randbereich 33 auf, über den der Faden 22 streifend abläuft. Der Speicherabschnitt 32 dient zur Aufnahme eines Fadenwickels 34, der durch den über den Einlaufbereich 31 zulaufenden Faden fortwährend geringfügig axial vorwärts bewegt wird. Das Fadenlieferrad 15 ist vorzugsweise im Wesentlichen hohl ausgebildet. Nach unten ist es mit einer geschlossenen Stirnwand abgeschlossen. Der von dem Fadenlieferrad 15 umschlossene Innenraum wird durch den Boden 27 und den ihn nach unten übergreifenden Rand 30 wirksam vor Fluseintrag geschützt.The latter is preferably formed as a sheet deep-drawn part in one piece. It has, for example, starting from an upper edge a conically steeply downwardly tapering
In dem Innenraum 29 sind ein oder mehrere elektrische und/oder elektronische Bauelemente 35, 36, 37, 38, 39, 40 angeordnet, die, wie
Die Schutzrohrkontaktrelais 35, 37 sind beispielsweise zur Erfassung der Straffheit bzw. des Durchhangs oder Fehlens des Fadens 22 vorgesehen. Dazu können ein Einlauffühler 44 und ein Auslauffühler 45 dienen, die an ihren Enden Ösen tragen, durch die der Faden 22 läuft. Fehlt der Faden oder hängt er durch schwenken die Fadenfühler 44, 45 aus den in den Figuren gezeigten Positionen in geeigneter Richtung aus und bewegen dabei Magnete, wie beispielsweise einen Permanentmagneten 46 von dem jeweiligen Schutzrohrkontaktrelais weg. Dies kann sofort oder nach einer sinnvoll gewählten Verzögerungszeit mittels der Leuchtdioden 39 zur Anzeige gebracht werden. Zwischen dem Einlauffühler 44 und dem Knotenfänger 25 ist die Fadenbremse (vorzugsweise ohne jegliche Fadenöse) vorzugsweise das einzige den Faden berührende Element.The protective tube contact relays 35, 37 are provided, for example, for detecting the tightness or slack or absence of the
Wie
Das insoweit beschriebene Fadenliefergerät 1 arbeitet nach dem Prinzip eines Positivfournisseurs. Wenn ein nicht weiter veranschaulichter Riemen über die Riemenscheibe 16 oder 17 das Fadenlieferrad 15 in Drehung versetzt, wickelt dieses den Faden 22 ständig auf. Dieser läuft über den Einlaufbereich 31 auf den Speicherabschnitt 32. Das Fadenlieferrad 15 gibt den Faden mit definierter Fadengeschwindigkeit über die Auslaufösen 47, 48 ab. Der Einlauffühler 44 und der Auslauffühler 45 befinden sich in ihren Arbeitspositionen. Die elektronische Schaltung auf der Leiterplatte 41 erkennt dies und die Leuchtdioden 39 leuchten nicht.The
Während des Betriebs kann sich Flus eventuell auf dem Träger 3, nicht aber auf dem zwischen der Riemenscheibe 16 und dem Fadenlieferrad 15 angeordneten Gehäuse 26 ablagern. Trotz seines relativ großen Volumens und geräumigen Innenraums bleibt es somit außen sauber. Seine im Beispielsfalle durchsichtigen Außenseiten bleiben sauber. Die im Innenraum angeordneten Leuchtelemente bleiben von allen Seiten sichtbar.During operation, Flus may possibly deposit on the
Aufgrund der verbesserten Sauberkeit des Geräts und der verbesserten Sichtbarkeit der Leuchtelemente wird davon ausgegangen, dass die Akzeptanz des Geräts beim Endnutzer verbessert ist.Due to the improved cleanliness of the device and the improved visibility of the light elements, the acceptance of the device by the end user is expected to be improved.

Von besonderem Vorteil ist bei dem erfindungsgemäßen Konzept, dass es eine Modulbauweise des Fadenliefergeräts 1 ermöglicht. Der aus dem Auslauffühler 45 und den Auslaufösen 47, 48 nebst sonstigen Elementen gebildete Auslaufabsteller ist eine Baugruppe, die von dem Fadenliefergerät abgenommen werden kann, ohne es von dem Maschinenring zu lösen. Gleiches gilt für das Fadenlieferrad 15 und das Gehäuse 26 mit der in ihm angeordneten Elektronik. Das neue Fadenliefergerät 1 ist deshalb besonders wartungsfreundlich.Of particular advantage in the inventive concept is that it allows a modular construction of the
Das erfindungsgemäße Fadenliefergerät weist einen Träger 3 auf, der seine Lagereinrichtungen 6, 7 mit einer Klemme 4 verbindet. Zwischen den Lagereinrichtungen 6, 7 ist zumindest eine Riemenscheibe 16 zum Antrieb einer vertikalen, von den Lagereinrichtungen 6, 7 gelagerten Welle 14 versehen, die an ihrem unteren Ende ein Fadenlieferrad trägt. Zwischen der unteren Riemenscheibe 16 und dem Fadenlieferrad 15 ist ein Gehäuse 26 vorgesehen, das von dem Träger 3 gehalten wird und zur Unterbringung einer elektrischen oder elektronischen Schaltung dient. Das Gehäuse ist in einem flusgeschützten Bereich untergebracht und kann dabei relativ groß und voluminös ausgebildet sein.The yarn feeding device according to the invention has a
