Abstract
Description
Die Erfindung betrifft ein Verfahren zum Kühlen einer Webmaschine, die ein Webmaschinengestell, sowie Antriebe und Hilfseinrichtungen aufweist und eine Webmaschine zum Durchführen des Verfahrens.The invention relates to a method for cooling a weaving machine, which has a weaving machine frame, as well as drives and auxiliary devices, and to a weaving machine for carrying out the method.
Es ist bekannt, Websäle, in denen mehrere Webmaschinen aufgestellt sind, zu klimatisieren, um die zu verwebenden Produkte, insbesondere Kett- und Schussfäden, unter möglichst günstigen Verhältnissen weben zu können. Zu diesem Zweck wird klimatisierte Luft mit einer vorgegebenen Temperatur und Feuchtigkeit in den Websaal eingebracht. Da die Webmaschinen selbst relativ viel Wärme erzeugen, muß die Luft des Websaals regelmäßig erneuert werden. Um dies zu ermöglichen, ist eine relativ große Klimaanlage notwendig, die relativ viel Energie verbraucht, um die große Menge an klimatisierter Luft zur Verfügung zu stellen.It is known to air-condition weaving halls in which several weaving machines are set up in order to be able to weave the products to be woven, in particular warp and weft threads, under the most favorable conditions possible. For this purpose, conditioned air with a specified temperature and humidity is brought into the weaving room. Since the weaving machines themselves generate a lot of heat, the air in the weaving room has to be renewed regularly. To make this possible, a relatively large air conditioning system is required, which consumes a relatively large amount of energy in order to provide the large amount of conditioned air.
Es ist auch bekannt (EP-A 0 286 162), einen von außerhalb des Websaals kommenden Luftstrom entlang den wärmeerzeugenden Teilen der Webmaschine strömen zu lassen und diesen Luftstrom unmittelbar aus dem Websaal herauszuführen, so daß der Websaal weniger stark aufgeheizt wird. Dadurch ist es möglich, einen Teil der von den Webmaschinen erzeugten Wärme unmittelbar abzuführen und dadurch die Menge der benötigten klimatisierten Luft zu beschränken.It is also known (EP-A 0 286 162) to allow an air flow coming from outside the weaving room to flow along the heat-generating parts of the weaving machine and to lead this air flow directly out of the weaving room so that the weaving room is heated less strongly. This makes it possible to dissipate part of the heat generated by the looms directly and thereby limit the amount of conditioned air needed.
Schnellaufende Webmaschinen, insbesondere Greifer-Webmaschinen, enthalten Webmaschinenteile, welche relativ viel Wärme erzeugen. Dadurch entsteht das Problem, daß die Kettfäden, die sich in der Nähe der Seitenrahmen des Maschinengestells der Webmaschine befinden, verstärkt austrocknen. Diese Gefahr besteht auch, wenn der Webmaschinensaal gut klimatisiert ist. Das Austrocknen dieser Kettfäden hat eine erhöhte Anzahl von Fadenbrüchen in dem seitlichen Bereich zur Folge.High-speed weaving machines, in particular rapier weaving machines, contain weaving machine parts which generate a relatively large amount of heat. This creates the problem that the warp threads, which are located near the side frames of the machine frame of the weaving machine, dry out more. This danger also exists if the weaving machine room is well air-conditioned. The drying of these warp threads results in an increased number of thread breaks in the side area.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum verbesserten Kühlen einer Webmaschine der eingangs genannten Art zu schaffen.The invention has for its object to provide a method for improved cooling of a weaving machine of the type mentioned.
Diese Aufgabe wird dadurch gelöst, daß wenigstens ein Teil des Maschinengestells und/oder einer oder mehrere der Antriebe oder der Hilfseinrichtungen mittels eines Kühlflüssigkeitskreislaufs auf etwa Umgebungstemperatur gekühlt werden.This object is achieved in that at least some of the machine frame and / or one or more of the drives or the auxiliary devices are cooled to approximately ambient temperature by means of a coolant circuit.
Aufgrund der Erfindung ist es möglich, die in der Webmaschine entstehende Wärme gezielt abzuführen und die Webmaschinenteile auf einer vorgegebenen Temperatur zu halten. Damit wird erreicht, daß alle Kettfäden über die Breite der Webmaschine eine gleichmäßige Temperatur und Feuchtigkeit aufweisen. Darüber hinaus wird auch erreicht, daß bei einem erneuten Start einer Webmaschine nach einem Stillstand weniger Schäden an der Webmaschine auftreten können.Because of the invention, it is possible to remove the heat generated in the weaving machine in a targeted manner and to keep the weaving machine parts at a predetermined temperature. This ensures that all warp threads have a uniform temperature and humidity across the width of the weaving machine. In addition, it is also achieved that less damage to the weaving machine can occur when a weaving machine is restarted after a standstill.
Bei einer erfindungsgemäßen Webmaschine zum Durchführen des Verfahrens wird vorgesehen, daß die Seitenrahmen und/oder einer oder mehrere der Antriebe oder der Hilfseinrichtungen mit Wärmetauschmitteln versehen sind, die an einen Kühlflüssigkeitskreislauf angeschlossen sind. Diese Wärmetauschelemente werden vorzugsweise in unmittelbarer Nähe der wärmeerzeugenden Elemente der Webmaschine angeordnet, so daß eine gezielte Kühlung erhalten wird.In a weaving machine according to the invention for carrying out the method, it is provided that the side frames and / or one or more of the drives or the auxiliary devices are provided with heat exchange means which are connected to a coolant circuit. These heat exchange elements are preferably arranged in the immediate vicinity of the heat-generating elements of the weaving machine, so that targeted cooling is obtained.

Den Webmaschinen (2) sind Vorlaufleitungen (7) für die kalte Kühlflüssigkeit zugeordnet, die beispielsweise auf der Kettbaumseite der Webmaschinen (2) verlaufen. Auf der gegenüberliegenden Seite, der Warenbaumseite, sind gestrichelt dargestellte Rücklaufleitungen (8) angeordnet, die die erwärmte Kühlflüssigkeit zu der Kühleinrichtung (6) zurückführen. Die Rücklaufleitungen (8) sind vorzugsweise isoliert, um die von ihnen transportierte Wärme nicht in den Websaal (1) gelangen zu lassen.In Fig. 1 a weaving room (1) is shown, in which several weaving machines (2) are set up. An air conditioning system (3) is assigned to the weaving room (1), which supplies conditioned air to the weaving room (1) via several supply lines (4). The weaving room (1) is provided with outflow openings (5), which may contain dust filters in order to discharge the heated air from the weaving room (1). In addition, the weaving machines (2) are connected to a central coolant circuit. This coolant circuit contains a cooling device (6) arranged outside the weaving room (1) for cooling and pumping around a coolant. Flow lines (7) for the cold cooling liquid are assigned to the weaving machines (2) and run, for example, on the warp beam side of the weaving machines (2).

In Fig. 2 und 3 ist schematisch eine einzelne Webmaschine (2) dargestellt, von welcher im wesentlichen nur die Kettfäden (11), ein Warenbaum (17) und die beiden Seitenrahmen (18) eines Maschinengestells dargestellt sind. In den Seitenrahmen (18) der Webmaschine (2) befinden sich wärmeerzeugende Webmaschinenteile, die mit den Bezugszeichen 14 und 15 schematisch dargestellt sind. Diese wärmeerzeugenden Webmaschinenteile können z.B. ein Webladenantrieb, ein Greiferantrieb, ein Schaftantrieb, ein Ölbehälter für Schmieröl, ein Hauptantriebsmotor, ein Motor für die Tuchaufwicklung, ein Steuerschrank oder einer große Kräfte unterliegende Lagerung oder auch andere Maschinenteile sein. Diesen wärmeerzeugenden Webmaschinenteilen (14, 15) sowie den innenliegenden Bereichen der Seitenteile (18) ist eine Kühlflüssigkeitskühleinrichtung (9) zugeordnet, die von dem Kühlmittel des zentralen Kühlflüssigkeitskreislaufes durchströmt wird. Diese Kühleinrichtung (9) enthält bei dem dargestellten Ausführungsbeispiel ein flaches Wärmetauschelement (10), das mit der Vorlaufleitung (7) verbunden ist und das im Bereich der Kettfäden (11) an den Seitenrahmen (18) angeordnet ist. Ferner sind Wärmetauschelemente (12) und (13) vorgesehen, die den wärmeerzeugenden Webmaschinenteilen (14, 15) derart zugeordnet sind, daß sie lokal von diesen Webmaschinenteilen (14, 15) die Wärme abführen. Die einzelnen Wärmetauschelemente (10, 12, 13) sind durch Verbindungsleitungen (16) miteinander und mit der Rücklaufleitung (8) verbunden. Die Wärmetauschelemente (10, 12, 13) bestehen aus von der Kühlflüssigkeit durchströmten Wärmetauschern, die eine große Kontaktfläche bezüglich der zugeordneten Elemente aufweisen.2 and 3 a single weaving machine (2) is shown schematically, of which essentially only the warp threads (11), a fabric tree (17) and the two side frames (18) of a machine frame are shown. In the side frame (18) of the loom (2) there are heat-generating loom parts, which are shown schematically with the
Bei dem Ausführungsbeispiel nach Fig. 2 und 3 sind die Seitenrahmen (18) und die darin enthaltenen Webmaschinenteile jeweils mit einer eigenen Kühleinrichtung (9) versehen. Diese Kühleinrichtungen (9) enthalten in der Verbindung zur Vorlaufleitung jeweils eine Umwälzpumpe (19), die von einer Steuereinheit (22) gesteuert wird und die zugeführte Kühlflüssigkeitsmenge bestimmt. An die Steuereinheit (22), die in die Steuereinheit der Webmaschine integriert sein kann, sind innerhalb der Seitenrahmen (18) angeordnete Temperaturfühler (21) und der Verbindung zu der Rücklaufleitung (8) zugeordnete Temperaturfühler (20) angeschlossen. Mittels der Temperaturfühler (20, 21) steuert die Steuereinheit (22) über die Pumpen (19) die zugeführte Kühlflüssigkeitsmenge temperaturabhängig. Es wird eine Kühlflüssigkeit mit einem möglichst großen Wärmeübergangskoeffizienten benutzt, beispielsweise Wasser, das gegebenenfalls mit Additiven versehen ist. Wasser ist billig, umweltsicher und auch unbrennbar.In the embodiment according to FIGS. 2 and 3, the side frames (18) and the weaving machine parts contained therein are each provided with their own cooling device (9). These cooling devices (9) each contain a circulation pump (19) in the connection to the flow line, which is controlled by a control unit (22) and determines the amount of cooling liquid supplied. To the control unit (22) which is in the control unit of the Weaving machine can be integrated, temperature sensors (21) arranged within the side frame (18) and temperature sensors (20) associated with the connection to the return line (8) are connected. By means of the temperature sensors (20, 21), the control unit (22) controls the quantity of coolant supplied via the pumps (19) as a function of the temperature. A cooling liquid with a heat transfer coefficient that is as large as possible is used, for example water, which is optionally provided with additives. Water is cheap, environmentally safe and also non-flammable.
Um unter möglichst idealen Verhältnissen weben zu können, wird von der Klimaanlage (3) dem Websaal klimatisierte Luft mit einer vorgegebenen Temperatur und Feuchtigkeit zugeführt, beispielsweise mit einer Temperatur von 22°C und einer relativen Luftfeuchtigkeit von 65%. Dadurch wird erreicht, daß die Temperatur in dem Websaal (1) beispielsweise 24°C beträgt. Um die wärmeerzeugenden Webmaschinenteile zusätzlich zu kühlen, wird von dem zentralen Kühlflüssigkeitskreislauf mit der Kühleinrichtung (6) eine Kühlflüssigkeit umgewälzt, die den Webmaschinen (2) zugeführt wird, um die dort erzeugte Wärme lokal aufzunehmen und aus dem Websaal abzutransportieren. Dabei wird angestrebt, daß die Temperatur dieser Webmaschinenteile in etwa der Temperatur der Luft in dem Websaal (1) entspricht. Die mit dem zentralen Kühlflüssigkeitskreislauf zugeführte Kühlflüssigkeit hat in etwa die Temperatur der dem Websaal (1) zugeführten, klimatisierten Luft, d.h. beispielsweise 22°C. Die Kühlflüssigkeit wird mit einer solchen Kühlflüssigkeitsmenge den einzelnen Webmaschinen (2) zugeführt, daß die in dem Bereich der Seitenrahmen (18) der Webmaschinen (2) befindlichen Webmaschinenteile, insbesondere die wärmeerzeugenden Webmaschinenteile (14, 15), bis auf eine Temperatur heruntergekühlt werden, die nur wenig höher liegt als die Temperatur der Luft in dem Websaal (1). Hierzu wird der Kühlflüssigkeitsdurchsatz mit Hilfe der von der Steuereinheit (22) gesteuerten Pumpen (19) geregelt, so daß die Temperatur der erwähnten Webmaschinenteile bei dem erläuterten Beispiel unter 32°C bleibt. Durch die Flüssigkeitskühlung der Webmaschine (2) wird erreicht, daß die Temperatur der erwähnten Webmaschinenteile in etwa der Temperatur der Luft in dem Websaal entspricht, so daß diese webmaschinenteile nur wenig Wärme in den Websaal abgeben und nur wenig Einfluß auf die in ihrer Nähe befindlichen Kettfäden (11) haben. Dadurch wird erreicht, daß die in der Nähe der Seitenrahmen (18) befindlichen Kettfäden (11) nicht verstärkt austrocknen, so daß alle Kettfäden (11) gleichmäßig klimatisiert werden. Dies hat den Vorteil, daß die Gefahr von Kettfadenbrüchen in den in der Nähe der Seitenrahmen (18) liegenden Kettfäden (11) verringert wird. Außerdem wird der Vorteil erreicht, daß dem Websaal (1) eine geringere Menge an klimatisierter Luft zugeführt werden muß,so daß der Energieverbrauch zum Erzeugen der klimatisierten Luft reduziert wird. Das Kühlen der Kühlflüssigkeit des Kühlflüssigkeitskreislaufes kann mittels einer relativ kleinen Kühleinrichtung (6) erfolgen, die außerhalb des Websaals angeordnet ist und die relativ wenig Energie verbraucht. Darüber hinaus ist es möglich, die Energie der erwärmten Kühlflüssigkeit zu benutzen, um andere Anlagen aufzuwärmen.In order to be able to weave under ideal conditions, the air conditioning system (3) supplies conditioned air to the weaving room with a predetermined temperature and humidity, for example with a temperature of 22 ° C. and a relative humidity of 65%. It is thereby achieved that the temperature in the weaving room (1) is, for example, 24 ° C. In order to additionally cool the heat-producing loom parts, the central coolant circuit with the cooling device (6) circulates a coolant which is fed to the looms (2) in order to absorb the heat generated there and to remove it from the weaving room. The aim is that the temperature of these weaving machine parts corresponds approximately to the temperature of the air in the weaving room (1). The coolant supplied with the central coolant circuit has approximately the temperature of the conditioned air supplied to the weaving room (1), ie for example 22 ° C. The cooling liquid is supplied to the individual weaving machines (2) with a quantity of cooling liquid such that the weaving machine parts located in the area of the side frames (18) of the weaving machines (2), in particular the heat-generating weaving machine parts (14, 15), are cooled down to a temperature. which is only slightly higher than the temperature of the air in the weaving room (1). For this purpose, the coolant throughput is regulated with the aid of the pumps (19) controlled by the control unit (22), so that the temperature of the above-mentioned weaving machine parts is explained Example remains below 32 ° C. The liquid cooling of the weaving machine (2) ensures that the temperature of the above-mentioned weaving machine parts corresponds approximately to the temperature of the air in the weaving room, so that these weaving machine parts only emit little heat into the weaving room and have little influence on the warp threads in their vicinity (11) have. This ensures that the warp threads (11) located in the vicinity of the side frames (18) do not dry out to a greater extent, so that all the warp threads (11) are air-conditioned uniformly. This has the advantage that the risk of warp thread breaks in the warp threads (11) lying near the side frames (18) is reduced. In addition, the advantage is achieved that a smaller amount of conditioned air has to be supplied to the weaving room (1), so that the energy consumption for generating the conditioned air is reduced. The cooling liquid of the cooling liquid circuit can be cooled by means of a relatively small cooling device (6) which is arranged outside the weaving room and which consumes relatively little energy. It is also possible to use the energy of the heated coolant to warm up other systems.
Durch die Kühlung der Webmaschinen (2) wird zusätzlich der Vorteil erhalten, daß die Temperatur der Webmaschinen (2) relativ konstant bleibt, so daß weniger thermische Spannungen in den mechanischen Maschinenteilen entstehen, die sich im Bereich der Seitenrahmen (18) befinden. Beim erneuten Start einer Webmaschine (2) nach längerem Stillstand ergeben sich somit weniger Schäden an diesen Webmaschinenteilen. Dadurch ist es auch möglich, kleinere Toleranzen für diese Webmaschinenteile vorzusehen, wodurch ein geringerer Verschleiß und geringere Schwingungen auftreten, was zur einer Reduzierung des Lärms in dem Websaal (1) führt. Außerdem ergibt sich die Möglichkeit, Schmieröl zu benutzen, das innerhalb eines relativ niedrigen Temperaturbereiches eine gute Schmierwirkung besitzt.The cooling of the weaving machines (2) additionally has the advantage that the temperature of the weaving machines (2) remains relatively constant, so that less thermal stresses arise in the mechanical machine parts which are located in the region of the side frames (18). When a weaving machine (2) is restarted after a long standstill there is less damage to these weaving machine parts. As a result, it is also possible to provide smaller tolerances for these weaving machine parts, as a result of which less wear and lower vibrations occur, which leads to a reduction in the noise in the weaving room (1). In addition, there is the possibility of using lubricating oil which has a good lubricating effect within a relatively low temperature range.
Die Tatsache, daß die Temperatur der Webmaschine (2) relativ konstant bleibt, führt zu dem weiteren Vorteil, daß weniger Webfehler auftreten, die auf einen unterschiedlichen Betrieb einer kalten oder einer etwas wärmeren Webmaschine (2) zurückzuführen sind. Wenn eine Webmaschine (2) nicht in Betrieb ist, betreibt die Steuereinheit (22) die Umweltspumpe (19) derart, daß die Webmaschinenteile nicht weiter gekühlt werden. Gegebenenfalls ist es möglich, den Kühlmittelfluß in der Webmaschine umzukehren, so daß warme Kühlflüssigkeit aus der Rücklaufleitung (8) den Webmaschinenteilen zugeführt wird, so daß die Webmaschinenteile von Webmaschinen, die außer Betrieb sind, dennoch auf Betriebstemperatur gehalten werden.The fact that the temperature of the weaving machine (2) remains relatively constant leads to the further advantage that fewer weaving errors occur which are due to different operation of a cold or a somewhat warmer weaving machine (2). If a weaving machine (2) is not in operation, the control unit (22) operates the environmental pump (19) in such a way that the weaving machine parts are no longer cooled. If necessary, it is possible to reverse the coolant flow in the weaving machine, so that warm coolant is fed from the return line (8) to the weaving machine parts, so that the weaving machine parts of weaving machines that are out of operation are nevertheless kept at operating temperature.
Das Messen der Temperatur der abgeführten Kühlflüssigkeit mittels des Temperaturfühlers (20) bietet weiter die Möglichkeit, eine außergewöhnliche Wärmeerzeugung festzustellen, die Anlaß zu einer Steigerung der Temperatur der Kühlflüssigkeit ist. Eine solche Wärmeerzeugung kann beispielsweise von einem gebrochenen Lager verursacht werden. Bei Feststellen einer gesteigerten Temperatur kann dann die Webmaschine (2) stillgesetzt werden.Measuring the temperature of the discharged coolant by means of the temperature sensor (20) also offers the possibility of detecting an unusual generation of heat, which is the reason for an increase in the temperature of the coolant. Such heat generation can be caused, for example, by a broken bearing. If an elevated temperature is detected, the weaving machine (2) can then be stopped.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß der Kühleinrichtung (6) Mittel zugeordnet werden, um die Temperatur der Kühlflüssigkeit und/oder die Temperatur in dem Websaal (1) zu messen. Diese Mittel können in einer Steuereinheit verarbeitet werden, um den Durchsatz und die Kühlung der Kühlflüssigkeit in der Kühleinrichtung (6) in Funktion von den gemessenen Temperaturen zu regeln.In a further embodiment of the invention, the cooling device (6) is assigned means to measure the temperature of the cooling liquid and / or the temperature in the weaving room (1). These means can be processed in a control unit in order to regulate the throughput and the cooling of the cooling liquid in the cooling device (6) as a function of the measured temperatures.
In weiterer Ausgestaltung können die Kühleinrichtungen (9) der einzelnen Webmaschinen (2) noch weitere Elemente enthalten, beispielsweise Ventile oder Temperaturfühler zum Erfassen der Temperatur des Websaals (1).In a further embodiment, the cooling devices (9) of the individual weaving machines (2) can also contain further elements, for example valves or temperature sensors for detecting the temperature of the weaving room (1).
