Definitions
- the invention relates to a heating device according to the preamble of claim 1, as known from CH-A 377 037.
- the guide surface for the material to be treated has thick-walled heating plates made of aluminum or magnesium which run at right angles to the movement path and into which cylindrical resistance heating elements are fitted. These heating elements directly heat up the heating plates, over the guide surface of which the material to be treated is drawn away.
- DE-C 893 108 and 930 888 electrically heated rollers are described, in which heating rods are inserted in axially extending grooves that are open to the outside on the circumference of the roller core.
- a heating device is created which has a uniform temperature over the entire width of the guideway, even if, for example, more heat is removed from the edge regions than the central region.
- So-called heat pipes partly filled with a liquid and partly filled with their vapor are known per se and are characterized by the fact that the steam is always deposited on the coolest wall parts and releases its heat of condensation there. This ensures an extremely even heat distribution over the entire length of the heat pipes and thus over the entire width of the guide surface without any delay and without any control intervention from the outside using the simplest constructional means.
- DE-B 22 11 658 shows an upright, elongated vessel, one wall of which is slightly curved as a guideway for the thread to be treated and electrical heating cartridges protrude into its lower part, which serves as a liquid collecting space.
- DE-C 18 04 777 and 19 53 692 heating godets with a cross-sectionally annular heat pipe in the godet jacket.
- US-A 36 19 539 a godet is shown, the entire slightly conical interior of which works as a heat pipe.
- the invention Compared to heating devices with a single, correspondingly large-volume steam vessel, the invention, with its large number of small heat pipes, offers significantly increased security. Even if one of the pipes leaks, only a very small amount of liquid escapes and cannot endanger the environment.
- the tubular shape of the heating elements and their small volume mean improved strength, especially since these small heat pipes are embedded in the surrounding metal support body. The failure of one of the heat pipes hardly affects the function of the entire heating device.
- the manufacture of such small heat pipes is very simple. For example, they can be cut from oxygen-free copper tubes and, after filling with a predetermined small amount of water, squeezed off at their ends and soldered or welded tightly.
- a plurality of threads 4 are pulled in the direction of arrows 3 over the heating plate 2 shown in FIG. 1, which is slightly curved on its surface 1.
- the heat pipes 6 are embedded in the support body 5, for example made of aluminum or brass, e.g. poured or thrown. These are copper or aluminum pipes of suitable wall thickness, e.g. with an outer diameter of 9mm and a wall thickness of 2mm.
- cylindrical heating rods 7 are also embedded in the support body 5 parallel to the heat pipes but offset relative to these, preferably cast or pressed in with the heat pipes 6 in one operation.
- the heat pipes 6 are tightly closed. They contain a small amount of a liquid, preferably water, which evaporates at the desired treatment temperature. They can be used up to temperatures of 360 ° C. When using aluminum tubes you can go up to 15o ° C. A steel support ring for the heat pipes would allow temperatures up to 250 ° C.
- the heating plate 2 is divided into several segments 2a to 2c, which can be heated to different temperatures if necessary. 2 shows a particularly advantageous structure of such segments.
- the heating plate here consists of an aluminum base body 8 tempered on its surface 1, which is provided on its side facing away from the thread running surface with semi-cylindrical grooves 9.
- the heat pipes 6 are inserted into these grooves and are held therein by a two-part supporting body 5a, 5b which has corresponding semi-cylindrical grooves 10 on its side facing the base body 8.
- a two-part supporting body 5a, 5b which has corresponding semi-cylindrical grooves 10 on its side facing the base body 8.
- each part 5a and 5b of the support body also has semi-cylindrical grooves 11, which together accommodate the heating rods 7.
- Both support body parts 5a and 5b are of the same shape and are produced, for example, as an aluminum drawing profile.
- the webs 12 provided on the base body 8 and widened at the end in a T-shape serve to fix the position of the support body 5a, 5b and the heat pipes 6 and the heating rods 7.
- flat springs 13 made of prestressed steel sheet are inserted between the T-shaped widenings 14 and the base body 8 supporting body part 5b facing away indented. If necessary, several such segments 2a to 2c of the base body can be lined up and braced in a suitable manner to form a large-area heating plate.
- the support body 5a, 5b can also be made of another good heat-conducting material, for example copper or brass.
- a resistance heating device is provided as the heating device for the heat pipes, in which heating rods embedded in the roller, roller or godet jacket and extending parallel to the godet shaft are supplied with current via slip rings.
- the resistance heating device can also be arranged in a stationary manner and the heat can be transmitted to the godet jacket and the heat pipes embedded therein by radiation or a transmission medium.

Description
Die Erfindung bezieht sich auf eine Heizeinrichtung gemäß Oberbegriff des Anspruchs 1, wie sie aus CH-A 377 037 bekannt ist. Dort weisen die Führungsfläche für das Behandlungsgut bildende dickwandige Heizplatten aus Aluminium oder Magnesium rechtwinklig zur Bewegungsbahn verlaufende Bohrungen auf, in welche zylindrische Widerstandsheizelemente eingepaßt sind. Diese Heizelemente heizen unmittelbar die Heizplatten auf, über deren Führungsfläche das Behandlungsgut hinweggezogen wird. In den DE-C 893 108 und 930 888 sind elektrisch beheizte Walzen beschrieben, bei denen Heizstäbe in axial verlaufende nach außen hin offenene Nuten am Umfang des Walzenkerns eingelegt sind.The invention relates to a heating device according to the preamble of
Mit der im Anspruch 1 gekennzeichneten Erfindung wird eine Heizeinrichtung geschaffen, welche über die gesamte Breite der Führungsbahn eine gleichmäßige Temperatur hat, auch wenn beispielsweise den Randbereichen mehr Wärme entzogen wird als dem mittleren Bereich.With the invention characterized in
Teils mit einer Flüssigkeit und teils mit deren Dampf gefüllte sogenannte Wärmerohre sind an sich bekannt und zeichnen sich dadurch aus, daß sich der Dampf stets an den kühlsten Wandteilen niederschlägt und dort seine Kondensationswärme abgibt. Damit wird verzögerungsfrei und ohne irgendwelchen Regeleingriff von außen mit einfachsten konstruktiven Mittteln eine äußerst gleichmäßige Wärmeverteilung über die gesamte Länge der Wärmerohre und damit über die gesamte Breite der Führungsfläche gewährleistet.So-called heat pipes partly filled with a liquid and partly filled with their vapor are known per se and are characterized by the fact that the steam is always deposited on the coolest wall parts and releases its heat of condensation there. This ensures an extremely even heat distribution over the entire length of the heat pipes and thus over the entire width of the guide surface without any delay and without any control intervention from the outside using the simplest constructional means.
Die Verwendung von auf dem Prinzip des Wärmerohrs beruhenden Heizvorrichtungen zur Wärmebehandlung von Fäden, Garnen, Bändern oder dergleichen ist an sich bekannt. So zeigt die DE-B 22 11 658 ein senkrecht stehendes, langgestrecktes Gefäß, dessen eine Wand als Führungsbahn für den zu behandelnden Faden leicht gekrümmt ist und in dessen unteren als Flüssigkeitssammelraum dienenden Teil elektrische Heizpatronen hineinragen. Weiterhin beschreiben die DE-C 18 04 777 und 19 53 692 Heizgaletten mit einem im Querschnitt ringförmigen Wärmerohr im Galettenmantel. In der US-A 36 19 539 ist eine Galette dargestellt, deren gesamter leicht konisch gestalteter Innenraum als Wärmerohr arbeitet.The use of heating devices based on the principle of the heat pipe for the heat treatment of threads, yarns, tapes or the like is known per se. For example, DE-B 22 11 658 shows an upright, elongated vessel, one wall of which is slightly curved as a guideway for the thread to be treated and electrical heating cartridges protrude into its lower part, which serves as a liquid collecting space. Farther describe DE-C 18 04 777 and 19 53 692 heating godets with a cross-sectionally annular heat pipe in the godet jacket. In US-A 36 19 539 a godet is shown, the entire slightly conical interior of which works as a heat pipe.
Aus DE-C 22 61 459 ist eine induktiv beheizte Galette mit einer innerhalb des Galettenmantels stationär angeordneten Induktionswicklung sowie einer zwischen der Induktionswicklung und dem aus magnetischem Material bestehenden Galettenmantel angeordneten, mit diesem hermetisch abgedichtet verbundenen Hülse bekannt. Der Ringraum zwischen der unmagnetischen Hülse und dem Galettenmantel ist mit einer dicken Schicht aus elektrisch hochleitfähigem Material ausgefüllt, welche über den Umfang verteilt eine Vielzahl axialer Durchgangsbohrungen aufweist. In diesen Bohrungen befindet sich ein Wärmeübetragungsmedium teils im flüssigen Zustand und teils als Sattdampf.From DE-C 22 61 459 an inductively heated godet with an induction winding arranged stationary within the godet casing and a sleeve arranged between the induction winding and the godet casing made of magnetic material and connected to this hermetically sealed is known. The annular space between the non-magnetic sleeve and the godet casing is filled with a thick layer of highly electrically conductive material, which has a large number of axial through holes distributed over the circumference. A heat transfer medium is partly in the liquid state and partly as saturated steam in these bores.
Gegenüber Heizvorrichtungen mit einem einzigen, entsprechend großvolumigen Dampfgefäß bietet die Erfindung mit ihrer Vielzahl kleiner Wärmerohre eine wesentlich erhöhte Sicherheit. Selbst beim Undichtwerden eines der Rohre tritt nur eine sehr geringe Flüssigkeitsmenge aus und kann die Umgebung nicht gefährden. Die Rohrform der Heizelemente und ihr geringes Volumen bedeuten eine verbesserte Festigkeit, zumal diese kleinen Wärmerohre in den sie umgebenden metallischen Tragkörper eingebettet sind. Der Ausfall eines der Wärmerohre beeinträchtigt die Funktion der gesamten Heizeinrichtung kaum. Außerdem ist die Herstellung solcher kleiner Wärmerohre denkbar einfach. Sie können beispielsweise aus sauerstoffreien Kupferrohren zugeschnitten und nach dem Füllen mit einer vorgegebenen geringen Menge Wasser an ihren Enden abgequetscht und dicht verlötet oder verschweißt werden. Sie werden in zylindrische Bohrung oder im Falle eines geteilten Tragkörpers in halbzylindrische Nuten eingesetzt. Sie können auch durch zylindrische oder anderweit geformte Hohlräume in einem metallischen Grundkörper gebildet sein. Die Beheizung der Wärmerohre erfolgt durch parallel zu ihnen im Tragkörper angeordnete Widerstandsheizstäbe. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Compared to heating devices with a single, correspondingly large-volume steam vessel, the invention, with its large number of small heat pipes, offers significantly increased security. Even if one of the pipes leaks, only a very small amount of liquid escapes and cannot endanger the environment. The tubular shape of the heating elements and their small volume mean improved strength, especially since these small heat pipes are embedded in the surrounding metal support body. The failure of one of the heat pipes hardly affects the function of the entire heating device. In addition, the manufacture of such small heat pipes is very simple. For example, they can be cut from oxygen-free copper tubes and, after filling with a predetermined small amount of water, squeezed off at their ends and soldered or welded tightly. They are used in cylindrical bores or, in the case of a split support, in semi-cylindrical grooves. They can also be formed by cylindrical or otherwise shaped cavities in a metallic base body. The heat pipes are heated by resistance heating rods arranged parallel to them in the supporting body. Further advantageous embodiments of the invention result from the subclaims.

- in perspektivischer Ansicht eine großflächige Heizplatte, wie sie beispielsweise zur Wärmebehandlung einer einem Schärbaum zugeführten Fadenschar dient; und
- Fig.2
- einen Schnitt parallel zur Fadenlaufrichtung durch einen Teil der Heizplatte.

- a perspective view of a large-area heating plate, such as that used for heat treatment of a thread group fed to a warp beam; and
- Fig. 2
- a section parallel to the direction of thread through a part of the heating plate.
über die in Fig.1 gezeigte, an ihrer Oberfläche 1 leicht gekrümmte Heizplatte 2 wird in Richtung der Pfeile 3 eine Vielzahl von Fäden 4 hinweggezogen. Rechtwinklig zur Fadenlaufrichtung 3 sind in den beispielsweise aus Aluminium oder Messing bestehenden Tragkörper 5 die Wärmerohre 6 eingebettet, z.B. eingegossen oder eingeschleudert. Es handelt sich um Kupfer- oder Aluminiumrohre geeigneter Wandstärke, z.B. mit einem Außendurchmesser von 9mm und einer Wandstärke von 2mm. Unterhalb der Reihe von Wärmerohren 6 sind zylindrische Heizstäbe 7 parallel zu den Wärmerohren aber gegenüber diesen auf Lücke versetzt ebenfalls in den Tragkörper 5 eingebettet, vorzugsweise in einem Arbeitsgang mit den Wärmerohren 6 eingegossen oder eingepreßt. Die Wärmerohre 6 sind dicht verschlossen. In ihnen befindet sich eine geringe Menge einer bei der gewünschten Behandlungstemperatur verdampfenden Flüssigkeit, vorzugsweise Wasser. Sie lassen sich bis zu Temperaturen von 360°C einsetzen. Bei Verwendung von Aluminiumrohren kann man bis 15o°C gehen. Ein Stahlstützring für die Wärmerohre würde Temperaturen bis zu 250°C gestatten.A plurality of
Die Heizplatte 2 ist in mehrere Segmente 2a bis 2c unterteilt, die im Bedarfsfall auf unterschiedliche Temperaturen aufgeheizt werden können. Fig.2 zeigt einen besonders vorteilhaften Aufbau solcher Segmente. Die Heizplatte besteht hier aus einem an seiner Oberfläche 1 vergüteten Aluminiumgrundkörper 8, der auf seiner der Fadenlauffläche abgewandten Seite mit halbzylindrischen Nuten 9 versehen ist. In diese Nuten sind die WÄrmerohre 6 eingelegt und werden darin durch einen zweigeteilten Tragkörper 5a,5b gehalten, der auf seiner dem Grundkörper 8 zugewandten Seite entsprechende halbzylindrische Nuten 10 aufweist. Diesen Nuten 10 gegenüberliegend hat jeder Teil 5a ud 5b des Tragkörpers ebenfalls halbzylindrische Nuten 11, welche zusammen die Heizstäbe 7 aufnehmen. Beide Tragkörperteile 5a und 5b sind von gleicher Gestalt und beispielsweise als Aluminiumziehprofil hergestellt. Die am Grundkörper 8 vorgesehenen, am Ende T-förmig verbreiterten Stege 12 dienen der Lagefixierung des Tragkörpers 5a,5b sowie der Wärmerohre 6 und der Heizstäbe 7. Hierzu werden Flachfedern 13 aus vorgespanntem Stahlblech zwischen die T-förmigen Verbreiterungen 14 und den dem Grundkörper 8 abgewandten Tragkörperteil 5b eingedrückt. Gegebenenfalls kann man mehrere solcher Segmente 2a bis 2c des Grundkörpers aneinanderreihen und in geigneter Weise zu einer großflächigen Heizplatte verspannen. Ein solcher Aufbau aus untereinander gleichen Baugruppen ist fertigungsmäßig und auch hinsichtlich der Lagerhaltung von Rohmaterialien und Halbzeugen besonders günstig. Anstatt aus Aluminium kann der Tragkörper 5a,5b auch aus einem anderen gut wärmeleitenden Werkstoff, z.B. Kupfer oder Messing bestehen.The heating plate 2 is divided into
Im Falle einer Heizrolle, Walze oder Galette ist als Heizvorrichtung für die Wärmerohre eine Widerstandsheizvorrichtung vorgesehen, bei der in den Rollen-, Walzen- bzw. Galettenmantel eingebettete und sich parallel zur Galettenwelle erstreckende Heizstäbe über Schleifringe mit Strom versargt werden. Die Widerstandsheizvorrichtung kann auch stationär angeordnet und die Wärme durch Strahlung oder ein übertragungsmedium auf den Galettenmantel und die darin eingebetteten Wärmerohre übertragen werden.In the case of a heating roller, roller or godet, a resistance heating device is provided as the heating device for the heat pipes, in which heating rods embedded in the roller, roller or godet jacket and extending parallel to the godet shaft are supplied with current via slip rings. The resistance heating device can also be arranged in a stationary manner and the heat can be transmitted to the godet jacket and the heat pipes embedded therein by radiation or a transmission medium.
