Definitions
- the invention relates to a method for cooling a rapier drive and a weaving machine with a coolable rapier drive.
- Various types of training are known for the grippers and their support members, as well as for their drive.
- a known type uses long, rigid rods, at one end of which the gripper is arranged for gripping and transferring the weft thread.
- the known rod-like support members are relatively stiff and low in mass.
- Such support members are made of fiber-reinforced plastic and have a U-shaped profile cross-section with an integrated rack-like toothing, with which at least one drive pinion is meshingly engaged with an alternating direction of rotation.
- All carrier elements connected to drive wheels and corresponding guides are subject to certain limits with regard to the weft insertion rate, in particular because of the frictional heat generated in the drive and guide area of the carrier elements.
- the friction leads to rapid wear of the elements involved in the drive and in guiding the carrier members.
- the operating time of the drive and guide elements is permanently impaired by the fiber fly which arises in the weaving process and which reaches the area of the rapier drive and the area of the guide elements.
- the invention is therefore based on the object, first in the field of Dissipating frictional heat generated by the drive and the guidance of the carrier organs and to achieve a targeted cooling of these organs and secondly the fiber fly occurring during the weaving process from the drive, To keep supporting and management bodies largely away.
- the task is characterized by the characteristic features of Claims resolved.
- the gripper drive which is formed from a rack-like support member and from at least one pinion driven with an alternating direction of rotation, and the drive being surrounded by a housing shielding the fiber flight, is supplied with or removed from an air-conditioned medium under pressure.
- the housing is connected to a pressure line, via which the conditioned medium is supplied or withdrawn from the housing under pressure. If the medium is supplied, it flows around the area of the gripper drive and reaches the guide rollers, which are also cooled, via slot-like openings which exist between the housing wall surrounding the carrier element on the one hand and the guide rollers or the bearing plate and the housing wall on the other hand.
- the pressure line is connected to a vacuum source, which creates a negative pressure in the housing.
- air is drawn into the housing, for example from the atmosphere, via the slot-like openings.
- Such a solution can be used, for example, in the production of technical fabrics, from monofilaments in warp and weft.
- the compressed air leads to a significant drop in temperature on the gripper drive and on the guides of the carrier member.
- the air flow exiting the slot-like openings with overpressure ensures that fiber fly cannot settle in the area of the gripper drive and, on the other hand, during vacuum operation, the fiber fly is removed from the suction air flow.
- the solution according to the invention increases the wear resistance of the organs involved in the weft insertion, in particular the carrier organs, the drive pinion and the guide rollers. Due to the cooling of the drive, support and guiding elements from the air-conditioned medium, a performance increase of the weaving machine of about 10% is achieved and finally the medium emerging from the outflow openings at a certain speed ensures that an accumulation of fiber fly on the gripper drive elements and is avoided in their environment and thus it is excluded that fiber fly mixed with oil or fat-containing abrasion particles can get from the gripper drive into the tissue to be produced.
- the invention is explained below using an exemplary embodiment.
- the drawing shows the gripper drive and the surrounding housing in perspective.
- the exemplary embodiment is based on the carrier element 1 for the weft thread, a gripper bar which carries at its front end a gripper 2 which has devices for gripping, holding and releasing the weft thread.
- the design of the gripper 2 is not important for the invention. It is therefore not discussed in any more detail.
- the carrier member 1 here consists of a U-shaped profile cross section with an integrated rack or rack-like toothing, with which at least one drive pinion 7 is meshingly engaged.
- the drive pinion 7 is non-rotatably connected to a drive shaft 7a, which drives the drive pinion 7 with an alternating direction of rotation according to double arrow 11.
- the direction of rotation of the drive pinion 7 and the direction of movement of the carrier member 1 with the gripper 2 is indicated by a double arrow 11, 12.

Description
Die Erfindung betrifft ein Verfahren zum Kühlen eines Greiferantriebes und eine
Webmaschine mit kühlbarem Greiferantrieb.
Für die Greifer und ihre Trägerorgane, sowie für ihren Antrieb sind verschiedenartige
Ausbildungen bekannt. Eine bekannte Art verwendet lange, steife Stangen,
an deren einem Ende der Greifer zur Erfassung und Übergabe des Schußfadens
angeordnet ist.
Die bekannten stangenartigen Trägerorgane sind verhältnismäßig steif und zugleich
massearm ausgebildet. Derartige Trägerorgane bestehen aus faserverstärktem
Kunststoff und besitzen einen U-förmigen Profilquerschnitt mit einer
integrierten zahnstangenartigen Verzahnung, mit der wenigstens ein Antriebsritzel
mit wechselndem Drehsinn kämmend in Eingriff steht.The invention relates to a method for cooling a rapier drive and a weaving machine with a coolable rapier drive.
Various types of training are known for the grippers and their support members, as well as for their drive. A known type uses long, rigid rods, at one end of which the gripper is arranged for gripping and transferring the weft thread.
The known rod-like support members are relatively stiff and low in mass. Such support members are made of fiber-reinforced plastic and have a U-shaped profile cross-section with an integrated rack-like toothing, with which at least one drive pinion is meshingly engaged with an alternating direction of rotation.
Andere Trägerorgane bestehen aus flexiblen Bändern, an deren einem Ende ein Greifer sitzt, während das andere Ende mit einem Antriebsrad in Verbindung steht (BE-A-1 000 506). Die Bänder müssen eine gewisse Steifigkeit aufweisen und zugleich flexibel genug sein, um auf das Antriebsrat, das mit wechselndem Drehsinn angetrieben wird, auf- und abgewickelt zu werden.Other support organs consist of flexible bands, one end of which The gripper sits while the other end is connected to a drive wheel (BE-A-1 000 506). The tapes must have a certain stiffness and at the same time be flexible enough be on the drive council, which is driven with alternating sense of rotation, to be wound up and wound up.
Allen mit Antriebsrädern und entsprechenden Führungen in Verbindung stehenden
Trägerorganen sind im Hinblick auf die Schußeintragsleistung, insbesondere
wegen der im Antriebs- und Führungsbereich der Trägerorgane entstehenden
Friktionswärme, gewisse Grenzen gesetzt.
Insbesondere dann, wenn die Materialpaarung zwischen Trägerorgan und Antriebsritzel
auf einer Kunststoffbasis beruht, führt die Friktion zu einem schnellen
Verschleiß der am Antrieb und an der Führung der Trägerorgane beteiligten
Elemente.
Ferner wird die Betriebsdauer der Antriebs- und Führungsorgane nachhaltig durch
den im Webprozeß entstehenden und in den Bereich des Greiferantriebs sowie in
den Bereich der Führungsorgane gelangenden Faserflug beeinträchtigt.All carrier elements connected to drive wheels and corresponding guides are subject to certain limits with regard to the weft insertion rate, in particular because of the frictional heat generated in the drive and guide area of the carrier elements.
Particularly when the material pairing between the carrier member and the drive pinion is based on a plastic, the friction leads to rapid wear of the elements involved in the drive and in guiding the carrier members.
Furthermore, the operating time of the drive and guide elements is permanently impaired by the fiber fly which arises in the weaving process and which reaches the area of the rapier drive and the area of the guide elements.
Der Erfindung liegt daher die Aufgabe zugrunde, erstens die im Bereich des Antriebs und der Führung der Trägerorgane entstehende Friktionswärme abzuführen und eine gezielte Kühlung dieser Organe zu erreichen und zweitens den während des Webprozesses entstehenden Faserflug von den Antriebs-, Träger- und Führungsorgane weitgehend fernzuhalten.The invention is therefore based on the object, first in the field of Dissipating frictional heat generated by the drive and the guidance of the carrier organs and to achieve a targeted cooling of these organs and secondly the fiber fly occurring during the weaving process from the drive, To keep supporting and management bodies largely away.
Erfindungsgemäß wird die Aufgabe durch die kennzeichnenden Merkmale der Patentansprüche gelöst.According to the invention the task is characterized by the characteristic features of Claims resolved.
Danach ist erfindungswesentlich, daß dem Greiferantrieb, welcher aus einem
zahnstangenartig ausgebildeten Trägerorgan und aus wenigstens einem mit
wechselndem Drehsinn angetriebenen Ritzel gebildet ist und wobei der Antrieb
von einem den Faserflug abschirmenden Gehäuse umgeben ist, unter Druck ein
klimatisiertes Medium zugeführt oder entzogen wird.
Dabei ist das Gehäuse an eine Druckleitung angeschlossen, über die das klimatisierte
Medium unter Druck dem Gehäuse zugeführt oder entzogen wird.
Wird das Medium zugeführt, umspült es den Bereich des Greiferantriebes und
gelangt über schlitzartige Öffnungen, die zwischen der das Trägerorgan umgebenden
Gehäusewandung einerseits und den Führungsrollen bzw. der Lagerplatte
und der Gehäusewandung andererseits bestehen, zu den Führungsrollen, die
ebenfalls gekühlt werden.
Wird das Medium dem Gehäuse entzogen, dann ist die Druckleitung an eine
Vakuumquelle angeschlossen, die im Gehäuse einen Unterdruck entstehen läßt.
Hierbei wird über die schlitzartigen Öffnungen Luft, z.B. aus der Atmosphäre in
das Gehäuse gesogen. Eine solche Lösung kann z.B. Anwendung finden bei der
Herstellung von technischen Geweben, aus Monofilen in Kette und Schuß.
In beiden Fällen führt die Druckluft zu einer deutlichen Temperaturabsenkung am
Greiferantrieb und an den Führungen des Trägerorgans.
In beiden Fällen besteht auch nicht mehr die Gefahr, daß Faserflug in den Bereich
des Greiferantriebs und der Rollenführungen gelangt.
Zum einen sorgt die mit Überdruck aus den schlitzartigen Öffnungen austretende
Luftströmung dafür, daß sich Faserflug nicht im Bereich des Greiferantriebes
absetzen kann und zum anderen wird bei Vakuumbetrieb der Faserflug von dem
Saugluftstrom abgeführt.Thereafter, it is essential to the invention that the gripper drive, which is formed from a rack-like support member and from at least one pinion driven with an alternating direction of rotation, and the drive being surrounded by a housing shielding the fiber flight, is supplied with or removed from an air-conditioned medium under pressure.
The housing is connected to a pressure line, via which the conditioned medium is supplied or withdrawn from the housing under pressure.
If the medium is supplied, it flows around the area of the gripper drive and reaches the guide rollers, which are also cooled, via slot-like openings which exist between the housing wall surrounding the carrier element on the one hand and the guide rollers or the bearing plate and the housing wall on the other hand.
If the medium is removed from the housing, the pressure line is connected to a vacuum source, which creates a negative pressure in the housing.
Here, air is drawn into the housing, for example from the atmosphere, via the slot-like openings. Such a solution can be used, for example, in the production of technical fabrics, from monofilaments in warp and weft.
In both cases, the compressed air leads to a significant drop in temperature on the gripper drive and on the guides of the carrier member.
In both cases there is no longer any danger that fiber fly will get into the area of the gripper drive and the roller guides.
On the one hand, the air flow exiting the slot-like openings with overpressure ensures that fiber fly cannot settle in the area of the gripper drive and, on the other hand, during vacuum operation, the fiber fly is removed from the suction air flow.
Mit der erfindungsgemäßen Lösung wird eine Erhöhung der Verschleißbeständigkeit
der am Schußeintrag beteiligten Organe, insbesondere der Trägerorgane,
des Antriebritzels und der Führungsrollen erzielt.
Durch die von dem klimatisierten Medium ausgehende Kühlung der Antriebs-,
Träger- und Führungsorgane wird eine Leistungssteigerung der Webmaschine von
etwa 10 % erreicht und schließlich sorgt das mit einer bestimmten Geschwindigkeit
aus den Ausströmöffnungen tretende Medium dafür, daß eine Ansammlung von
Faserflug an den Greiferantriebsorganen und in deren Umgebung vermieden wird
und damit ausgeschlossen ist, daß mit öl- oder fetthaltigen Abriebpartikeln versetzter
Faserflug aus dem Greiferantrieb in das herzustellende Gewebe gelangt.The solution according to the invention increases the wear resistance of the organs involved in the weft insertion, in particular the carrier organs, the drive pinion and the guide rollers.
Due to the cooling of the drive, support and guiding elements from the air-conditioned medium, a performance increase of the weaving machine of about 10% is achieved and finally the medium emerging from the outflow openings at a certain speed ensures that an accumulation of fiber fly on the gripper drive elements and is avoided in their environment and thus it is excluded that fiber fly mixed with oil or fat-containing abrasion particles can get from the gripper drive into the tissue to be produced.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles erläutert.
Die Zeichnung zeigt den Greiferantrieb und das umschließende Gehäuse in
perspektivischer Darstellung.The invention is explained below using an exemplary embodiment.
The drawing shows the gripper drive and the surrounding housing in perspective.
Dem Ausführungsbeispiel liegt als Trägerorgan 1 für den Schußfaden eine Greiferstange
zugrunde, die an ihrem vorderen Ende einen Greifer 2 trägt, der Einrichtungen
zum Erfassen, Festhalten und Freigeben des Schußfadens besitzt.
Die Ausbildung des Greifers 2 ist für die Erfindung nicht von Bedeutung. Es wird
daher darauf nicht näher eingegangen.
Das Trägerorgan 1 besteht hier aus einem U-förmigen Profilquerschnitt mit integrierter
Zahnstange bzw. integrierter zahnstangenartiger Verzahnung, mit der
wenigstens ein Antriebsritzel 7 kämmend in Eingriff steht.
Das Antriebsritzel 7 ist mit einer Antriebswelle 7a drehfest verbunden, welche das
Antriebsritzel 7 mit wechselndem Drehsinn gemäß Doppelpfeil 11 antreibt.
Die Drehrichtung des Antriebsritzels 7 und die Bewegungsrichtung des Trägerorgans
1 mit dem Greifer 2 ist durch jeweils einen Doppelpfeil 11,12 angedeutet.
Die Lagerung und Führung des Trägerorgans 1 erfolgt hier im Beispiel durch
Rollen 4, 5, 6.
Eine Lagerplatte 3, die in nicht näher beschriebener Weise maschinenfest angeordnet
ist, trägt um horizontal liegende Achsen drehend gelagerte Führungsrollen
4,5. Die Rollen 4,5 dienen der Vertikalführung des Trägerorgans 1.
Die seitliche Führung des Trägerorgans 1 erfolgt durch wenigstens eine Führungsrolle

Zwischen dem Trägerorgan 1 und der das Trägerorgan 1 umschließenden
Schnittfläche der Wand 8a des nach oben hin offenen Gehäuses 8 und zwischen
der Unterseite der die Führungsrollen 4,5,6 tragenden Lagerplatte 3 und der
Schnittfläche der Wand 8a sind schlitzartige Öffnungen 9 vorhanden, welche einen
Durchgang für Luftströmungen bilden.
Zum Beispiel auf der Frontseite ist das Gehäuse 8 an eine Druckleitung 10 anschließbar,

so erfolgt die Kühlung des Greiferantriebs durch die über die Öffnungen 9 von
außen in das Gehäuseinnere gesogene und über die Druckleitung 10 abgeführte
