Description

Die Erfindung bezieht sich auf eine Trockenanlage für Färbespulen in der Textilindustrie, die zum Färben gleichzeitig auf ein perforiertes Rohr aufgesteckt sind, über welches das flüssige Färbemittel durch die Spulen gepreßt wird.The invention relates to a drying system for dyeing bobbins in the textile industry, which are simultaneously attached to a perforated tube for dyeing, via which the liquid colorant is pressed through the bobbins.

Zum Trocknen werden die Spulen von Rohr abgenommen, in einer mechanischen Vorrichtung, z.B. durch eine Zentrifuge vorgetrocknet und anschließend in einem Hochfrequenzofen fertig getrocknet. In diesen Ofen wird zur Vergleichmäßigung der Erwärmung und zur Abführung von entstehenden Dampfschwaden noch zusätzlich Heißluft eingeblasen und wieder abgesaugt.For drying, the coils are removed from the tube in a mechanical device, e.g. predried by a centrifuge and then dried in a high-frequency oven. Hot air is also blown into this oven to even out the heating and to remove steam that is formed and is then extracted again.

Trockenvorrichtungen dieser Art haben sich gegenüber rein mechanischen Trockenvorrichtungen gut bewährt, die erforderliche Vereinzelung der Spulen steht jedoch einer weitgehenden Automatisierung des Materialflusses beim Trocknungsvorgang störend im Wege.Drying devices of this type have proven themselves well over purely mechanical drying devices, but the required separation of the coils hinders extensive automation of the material flow during the drying process.

Die Aufgabe der vorliegenden Erfindung besteht darin, bei einer Trocknungsanlage der eingangs genannten Art den Trocknungsvorgang weitgehend zu automatisieren und zu beschleunigen.The object of the present invention is to largely automate and accelerate the drying process in a drying system of the type mentioned at the outset.

Die Lösung dieser Aufgabe ist durch folgende Merkmale gekennzeichnet;

  • eine Vortrockenstation, in der Mittel zum Einblasen von Druckluft in das Rohr mit aufgesteckten Spulen vorgesehen sind,
  • eine folgende Zwischentrockenstation zum Abtrocknen der
The solution to this problem is characterized by the following features;
  • a pre-drying station, in which means for blowing compressed air into the tube with attached coils are provided,
  • a subsequent intermediate drying station to dry the

Oberflächen der auf dem Rohr aufgesteckten Färbespulen, eine nachgeschaltete Fertigtrockenstation mit einem Hochfrequenzofen zur kapazitiven Endtrocknung der Färbespulen auf dem Rohr undSurfaces of the dye spools attached to the tube, a downstream finished drying station with a high-frequency oven for the capacitive final drying of the dye spools on the tube and

eine Transportvorrichtung zum selbsttätigen Fördern der auf dem Rohr aufgesteckten Färbespulen durch die einzelnen Stationen, die zumindest im Bereich des Hochfrequenzofens mit Mitteln zur. Drehung des Rohres mit Färbespulen um seine Längsachse versehen ist.a transport device for automatically conveying the dye bobbins attached to the tube through the individual stations, which at least in the area of the high-frequency furnace with means for. Rotation of the tube is provided with dye spools around its longitudinal axis.

Durch eine derartige Behandlungsstraße läßt sich der Durchlauf und die Wärmebehandlungsdauer verkürzen und manuelle Arbeitszeit zum Vereinzeln der Werkstücke für den Trocknungsvorgang einsparen.Through such a treatment line, the throughput and the heat treatment time can be shortened and manual working time for separating the workpieces for the drying process can be saved.

Physikalisch gesehen, wird in der Vortrockenstation durch das Einblasen von Druckluft - z.B. mit 5 Atmosphären - ein großer Teil der Feuchtigkeit von Innen heraus durch die Färbespulen an die Oberfläche transportiert und von dort abgeführt. Eine auf diese Weise vorgetrocknete und aufgeschlossene Spule ist abernicht für eine anschließende Hochfrequenzbehandlung ohne weiteres geeignet, da durch die vorgenannte Trocknung besonders an der Oberfläche noch relativ viel Feuchtigkeit verbleibt, die zu Überschlägen im Hochfrequenzfeld Anlaß geben würde. Als Zwischenstation ist daher in der Straße zwischen mechanischer Vortrockenstation und Hochfrequenztrockner eine Oberflächentrocknung z.B. mit Infrarotstrahlern vorzusehen.From a physical point of view, in the pre-drying station, compressed air is blown in - e.g. with 5 atmospheres - a large part of the moisture is transported from the inside through the dyeing coils to the surface and removed from there. However, a coil that has been pre-dried and disrupted in this way is not readily suitable for subsequent high-frequency treatment, since due to the aforementioned drying, a relatively large amount of moisture remains on the surface, which would give rise to arcing in the high-frequency field. As an intermediate station, a surface drying is therefore in the street between the mechanical pre-drying station and the high-frequency dryer, e.g. to be provided with infrared radiators.

Zur Vereinfachung des mechanischen Aufbaus wird die Förderanlage im Bereich der mechanischen Vortrocknung vorzugsweise taktweise betrieben, d.h. während des Einblasens der Druckluft in die Rohre steht der betreffende Förderabschnitt still, dagegen kann in den übrigen Behandlungsstationen ein kontinuierlicher Fördervorgang laufen. Damit die Luft frei entweichen kann und die Spulen gleichmäßig getrocknet werden, ist die Transportvorrichtung, z.B. in Form eines Schleppkettenförderers mit Abstandshaltern versehen, in denen die Rohre mit Spulen eingelegt werden.To simplify the mechanical structure, the conveyor system in the area of the mechanical predrying is preferably operated intermittently, ie the conveying section in question stands still while the compressed air is being blown into the pipes, whereas a continuous conveying process can run in the other treatment stations. So that the air can escape freely and the spu len are evenly dried, the transport device, for example in the form of a drag chain conveyor, is provided with spacers in which the tubes are inserted with coils.

Anhand einer Zeichnung sei die Erfindung näher erläutert;
es zeigen:

  • Figur 1 einen schematischen Längsschnitt durch die Trockenanlage und
  • Figur 2 einen Schnitt längs der Linie II-II in Figur 1.
The invention will be explained in more detail with reference to a drawing;
show it:
  • 1 shows a schematic longitudinal section through the drying plant and
  • FIG. 2 shows a section along the line II-II in FIG. 1.

Die Trockenanlage für die auf einem perforierten Rohr 52 aufgesteckten einzelnen Färbespulen 51 besteht aus einer mechanischen Vortrockenstation 1, einer Zwischentrockenstation 2 zur Oberflächentrocknung und einer nachgeschalteten Fertigtrockenstation 3. Die aus Rohr 52 und Färbespulen 51 bestehende Einheit 5 wird mittels einer Transportvorrichtung 4 durch die einzelnen Stationen in Richtung des Pfeiles 45 transportiert. Hierzu sind die Schleppketten 41 der Transportvorrichtung 4 mit Abstandshaltern 45 versehen, in die die Rohre samt den Spulen 51 eingelegt sind.The drying system for the individual dyeing bobbins 51 which are attached to a perforated tube 52 consists of a mechanical pre-drying station 1, an intermediate drying station 2 for surface drying and a downstream finished drying station 3. The unit 5 consisting of tube 52 and dyeing bobbins 51 is transported through the individual stations by means of a transport device 4 transported in the direction of arrow 45. For this purpose, the drag chains 41 of the transport device 4 are provided with spacers 45, into which the tubes together with the coils 51 are inserted.

Die Vortrockenstation 1 ist mit Anschlußvorrichtungen 12 für Druckluft 11 versehen, wobei gleichzeitig mehrere Rohre anzuschließen sind. Damit der Anschlußvorgang und die Trocknung mechanisch keine allzugroßen Schwierigkeiten bereiten, wird während dieses Vorganges die Fördereinrichtung 4 in dem Teil 43, der sich in der Vortrockenstation 1 befindet, gestoppt. Sind die Färbespulen durch das Einblasen von Druckluft von z.B. 5 Atmosphären Druck ausreichend mechanisch vorgetrocknet und aufgeschlossen, so gelangen die Einheiten 5 in eine Zwischentrockenstation 2, die mit Infrarotstrahlern 21 versehen ist. Hier wird die Oberfläche der Färbespulen 51 von Feuchtigkeit befreit. Von hier aus gelangen dann die Färbespulen 51 auf dem Rohr 52 als komplette Einheit 5 zur Fertigtrocknung in die Station 3, die aus einem bekannten Hochfrequenzofen mit Elektroden 31 besteht. In diesen Ofen wird zusätzlich Heißluft 32 eingeblasen und wieder abgesaugt. Zur gleichmäßigen Trocknung der Färbespulen sind in diesem Bereich und gegebenenfalls auch noch im Bereich der Zwischentrockenstation 2 Mittel vorgesehen, mit denen das Rohr 58 um seine Längsachse in Richtung des Pfeiles 42 gedreht wird. Eine derartige Drehung ist erforderlich, wenn das Rohr mit den Spulen senkrecht zum Feldlinienverlauf im Hochfrequenzfofen liegt, da ansonsten ungleichmäßige Trocknungszonen entstehen würden. Eine derartige räumliche Anordnung hat den Vorteil, daß metallische Hülsen zum Wickeln der Färbespulen verwendet werden können, ohne daß das Feld kurzgeschlossen wird. Will man das Rohr in Richtung der elektrischen Feldlinien anordnen, so muß man Spulenkerne und Rohre aus Isoliermaterial vorsehen.The predrying station 1 is provided with connecting devices 12 for compressed air 11, several pipes being connected at the same time. So that the connection process and the drying are not mechanically very difficult, the conveying device 4 is stopped in the part 43, which is located in the predrying station 1, during this process. If the dyeing bobbins are sufficiently mechanically pre-dried and blown open by blowing in compressed air of, for example, 5 atmospheric pressure, the units 5 reach an intermediate drying station 2 which is provided with infrared radiators 21. Here the surface of the dyeing bobbins 51 is freed from moisture. This is where the dye comes from coil 51 on the tube 52 as a complete unit 5 for finished drying in the station 3, which consists of a known high-frequency oven with electrodes 31. Hot air 32 is additionally blown into this furnace and extracted again. For uniform drying of the dyeing bobbins 2 means are provided in this area and possibly also in the area of the intermediate drying station, with which the tube 58 is rotated about its longitudinal axis in the direction of arrow 42. Such a rotation is necessary if the tube with the coils lies perpendicular to the field line in the high-frequency oven, since otherwise uneven drying zones would result. Such a spatial arrangement has the advantage that metallic sleeves can be used to wind the dye spools without the field being short-circuited. If you want to arrange the pipe in the direction of the electrical field lines, you must provide coil cores and pipes made of insulating material.

Die Elektroden 31 - und damit auch die Transportvorrichtung - können auch vertikal - statt wie gezeigt horizontal - angeordnet sein.The electrodes 31 - and thus also the transport device - can also be arranged vertically instead of horizontally as shown.
