Description

Die Erfindung betrifft eine Muldenmangel nach dem Oberbegriff des Anspruches 1 bzw. des Anspruches 10.The invention relates to a trough defect according to the preamble of claim 1 and claim 10.

Bei allen derzeit in Gebrauch befindlichen Mehrmuldenmangeln ist eine Vielzahl paralleler, endloser Bänder um die Walzen und Brücken herumgeschlungen. Diese Bänder werden in entsprechenden Rollen, von denen mindestens eine gleichzeitig als Spannvorrichtung ausgebildet ist, seitlich geführt. Sie sorgen dafür, daß die aus dem Spalt zwischen der in Förderrichtung vorneliegenden Walze und der zugehörigen Mulde austretenden Wäschestücke glatt auf die dahinter angeordnete Brücke überführt und dann ebenso glatt und stoßfrei in den Spalt zwischen der in Förderrichtung hintenliegenden Walze und zugehörigen Mulde eingeleitet werden. Diese bekannten, im allgemeinen Gebrauch befindlichen Mangelbänder haben jedoch den entscheidenden Nachteil, daß sie verhältnismäßig leicht reißen. Angesichts der Vielzahl verwendeter Mangelbänder kommt es daher in relativ kurzen Abständen zu einem Stillstand der gesamten Maschine ; es muß dann das jeweils gebrochene Mangelband neu eingefädelt und verknotet werden. Ein weiterer Nachteil der bekannten Mangelbänder besteht darin, daß sie sich auf den Wäschestücken abdrücken.In the case of all multi-well ironers currently in use, a large number of parallel, endless belts are wrapped around the rollers and bridges. These bands are laterally guided in corresponding roles, at least one of which is simultaneously designed as a tensioning device. They ensure that the items of laundry emerging from the gap between the roller lying in the conveying direction and the associated trough are transferred smoothly to the bridge arranged behind them and are then introduced into the gap between the roller lying in the conveying direction and the associated trough just as smoothly and smoothly. However, these known deficiency bands in common use have the decisive disadvantage that they tear relatively easily. In view of the large number of shortage belts used, the entire machine comes to a standstill at relatively short intervals; the broken band of shortages must then be re-threaded and knotted. Another disadvantage of the known lack bands is that they are printed on the laundry.

Eine bei der Bildung des Oberbegriffes des Anspruches 1 bzw. des Anspruches 10 berücksichtigte Muldenmangel ist durch die US-A 2 643 473 bekanntgeworden. Bei dieser ist statt der Vielzahl paralleler, endloser Bänder ein sich über die gesamte Mangelbreite erstreckendes Endlostuch vorgesehen, das von verschiedenartigen Geradlaufeinrichtungen (von Hand in der Neigung verstellbare Spannrolle entsprechend Figur 1, seitliche Zwangsführung der Tuchränder nach den Figuren 3 bis 6, gewölbte Führungsrollen nach Figur 7) in der Betriebslage gehalten wird. Mit diesen Geradlaufeinrichtungen können jedoch die sehr großen, zeitlich stark variierenden Auslenkkräfte, wie sie bei derzeit in Gebrauch befindlichen, bis zu 4 m breiten Mehrmuldenmangeln auftreten, nicht beherrscht werden, da sie entweder überhaupt nicht oder zu langsam den sich zeitlich verändernden Betriebszuständen der Mehrmuldenmangel angepaßt werden können. Die DE-C 101 932 zeigt bei einer nicht gattungsgemäßen Plättmaschine, daß das erwähnte Problem des Geradlaufes flächiger Führungstücher schon vor dem Beginn dieses Jahrhunderts bekannt war und Lösungsmöglichkeiten vorgeschlagen wurden. Gleichwohl haben weder Führungstücher noch Geradlaufeinrichtungen bis zum Anmeldetag der vorliegenden Erfindung Eingang in die Praxis bei Hochleistungs-Mehrmuldenmangeln gefunden. Hier wurde es vielmehr trotz der eklatanten, ins Auge springenden Nachteile vorgezogen, weiterhin mit den bruchgefährdeten, schmalen Mangelbändern als Führungseinrichtung zu arbeiten.A trough lack considered in the formation of the preamble of claim 1 or claim 10 has become known from US-A 2 643 473. In this case, instead of the large number of parallel, endless belts, an endless cloth extending over the entire width of the mangle is provided, which is curved by different types of straight-running devices (tension roller adjustable by hand according to FIG. 1, lateral guidance of the cloth edges according to FIGS. 3 to 6) Figure 7) is held in the operating position. With these straight-running devices, however, the very large, time-varying deflection forces, such as those which are currently in use, up to 4 m wide multi-well deficiencies, cannot be mastered, since they either do not adapt at all or too slowly to the changing operating conditions of the multi-well lack can be. DE-C 101 932 shows in a non-generic flattening machine that the problem of straight running flat guiding cloths was known before the beginning of this century and possible solutions were proposed. Nonetheless, until the filing date of the present invention, neither guiding cloths nor straight-line devices have found their way into practice in the case of high-performance multi-well ironers. Rather, despite the blatant, obvious disadvantages, it was preferred to continue working with the narrow, vulnerable bands as a guiding device.

Diese Verhältnisse werden auch durch die GB-A 718 436 bestätigt, wo zwar ein endloses, mit einer Geradlaufeinrichtung versehenes Förderband vorgesehen ist, dieses aber offensichtlich aus den oben erwähnten Gründen nicht durch den Spalt zwischen den verdrehbaren Walzen und der zugehörigen Mulde hindurchgeführt ist. Die Geradlaufeinrichtung spricht zudem erst an, wenn das Förderband bereits weit aus seiner Solllage herausgewandert ist.These conditions are also confirmed by GB-A 718 436, where an endless conveyor belt provided with a straight running device is provided, but for the reasons mentioned above it is obviously not passed through the gap between the rotatable rollers and the associated trough. The straight running device also only responds when the conveyor belt has already moved far out of its desired position.

Aufgabe der vorliegenden Erfindung ist es, bei einer Muldenmangel nach dem Oberbegriff des Anspruches 1 bzw. des Anspruches 10 die Betriebslage des Endlostuches dauerhaft sicherzustellen.The object of the present invention is to permanently ensure the operating position of the endless cloth in the case of a trough defect according to the preamble of claim 1 or claim 10.

Diese Aufgabe wird durch die im Kennzeichen des Anspruches 1 bzw. des Anspruches 10 beschriebene Erfindung gelöst ; vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 9 angegeben.This object is achieved by the invention described in the characterizing part of claim 1 and claim 10; Advantageous developments of the invention are specified in claims 2 to 9.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert ; die einzige Figur zeigt schematisch die Seitenansicht einer Zweimuldenmangel (vordere Seitenwand-abgenommen).An embodiment of the invention is explained below with reference to the drawing; the only figure shows schematically the side view of a two-cavity ironer (front side wall removed).

Die dargestellte Zweimuldenmangel enthält in einem Gestell 1 in bekannter Weise zwei beheizte Mulden 2, 3, zwischen denen eine ebenfalls beheizte Brücke 4 angeordnet ist. In die Mulden 2, 3 taucht jeweils etwa mit der Hälfte ihres Umfanges eine hohle Walze 5, 6 ein, die mit einer nicht dargestellten Wrasen-Absaugvorrichtung versehen ist. Die Walzen 5, 6 sind an ihren Mantelflächen mit einer federnden Auflage versehen, die aber anders als bei bekannten Walzen nicht durch ein Walzentuch abgedeckt ist.The two-well lack shown contains in a frame 1 in a known manner two heated troughs 2, 3, between which a likewise heated bridge 4 is arranged. A hollow roller 5, 6, which is provided with a vapor extraction device (not shown), is immersed in each of the troughs 2, 3 with approximately half of its circumference. The rollers 5, 6 are provided on their outer surfaces with a resilient support which, however, unlike known rollers, is not covered by a roller cloth.

Ein Endlostuch aus Polyester oder einem ähnlichen wärme- und feuchtigkeitsbeständigen Kunststoff umschlingt die Walzen 5, 6, wozu es durch den Spalt zwischen der Mulde 2 und der Walze 5 über die Brücke 4 durch den Spalt zwischen der Mulde 3 und der Walze 6 und unter einem Pendelbalken 8 hindurch zurück zur Walze 5 geführt wird.An endless cloth made of polyester or a similar heat and moisture-resistant plastic wraps around the rollers 5, 6, for which it is through the gap between the trough 2 and the roller 5 over the bridge 4 through the gap between the trough 3 and the roller 6 and under one Pendulum beam 8 is guided back to the roller 5.

Das Endlostuch ist aus einer Tuchbahn hergestellt, die durch den beschriebenen Weg innerhalb der Muldenmangel eingefädelt und dann an den Stirnseiten mit einem Reißverschluß verbunden wird. Der Reißverschluß ist an der Seite, welche im Einbauzustand den Mulden 3, 2 zugewandt ist, durch ein überstehendes Stoffstück abgedeckt. Selbstverständlich kann das Tuch 7 auch stirnseitig zusammengenäht werden. Sofern dies die Konstruktion der Muldenmangel im übrigen zuläßt, kann das Endlostuch 7 auch von der Seite her eingeführt werden.The Endlostuch is made of a sheet of fabric, which is threaded through the described path within the trough lack and then connected to the front with a zipper. The zipper is covered on the side which faces the troughs 3, 2 in the installed state by a protruding piece of fabric. Of course, the cloth 7 can also be sewn together at the end. If this allows the construction of the trough lack for the rest, the endless cloth 7 can also be inserted from the side.

Der Pendelbalken 8 umfaßt eine freilaufende Walze oder Rolle 9, die im Bereich ihrer gegenüberliegenden Enden an zwei unabhängig voneinander betätigbaren ausfahrbaren Stellmotoren, z. B. Hydraulik- oder Pneumatikzylindern 10, (nur einer in der Zeichnung erkennbar) aufgehängt ist. Im Bereich einer Kante des Tuches 7 befindet sich mindestens eine die Position dieser Kante überwachende Fotozelle (nicht dargestellt).The pendulum beam 8 comprises a free-running roller or roller 9, which in the region of its opposite ends on two independently operable extendable servomotors, for. B. hydraulic or pneumatic cylinders 10, (only one recognizable in the drawing) is suspended. In the area of an edge of the cloth 7 there is at least one photo cell (not shown) monitoring the position of this edge.

Am in der Zeichnung rechten Ende ist schematisch eine Aufgabestation 12 für die Wäschestücke, am in der Zeichnung linken Ende ein pneumatischer Abstreifer 13 für die auslaufenden Wäschestücke dargestellt. Die Förderrichtung der dargestellten Muldenmangel ist also von rechts nach links.At the right end in the drawing, a feed station 12 for the laundry items is shown schematically, and at the left end in the drawing, a pneumatic scraper 13 for the outgoing laundry items is shown. The conveying direction of the trough lack shown is therefore from right to left.

In den vom Tuch 7 umschlossenen Raum mündet eine Absaugleitung 11, über die hier entstehende Dämpfe und dergleichen abgesaugt werden.A suction line 11 opens out into the space enclosed by the cloth 7, through which the vapors and the like which are produced here are sucked off.

Die beschriebene Muldenmangel funktioniert wie folgt :

  • Die Wäschestücke werden an der Aufgabestation in die Maschine eingeführt und gelangen dann in den Spalt zwischen dem Tuch 7 und der ersten Mulde 2. In diesem Spalt übernimmt das Tuch 7 offensichtlich die Funktion des bekannten Walzentuches mit.
The described lack of troughs works as follows:
  • The items of laundry are introduced into the machine at the loading station and then reach the gap between the cloth 7 and the first trough 2. In this gap, the cloth 7 obviously takes on the function of the known roller cloth.

Die Wäschestücke werden dann vom Tuch 7 über die beheizte Brücke 4 und dann in die zweite Mulde 3 eingeführt, wo das Tuch 7 wiederum die Funktion eines Walzentuches übernimmt.The items of laundry are then introduced from the cloth 7 over the heated bridge 4 and then into the second trough 3, where the cloth 7 in turn takes on the function of a roller cloth.

Am Ausgang der zweiten Mulde 3 richtet der pneumatische Abstreifer 13, der von einer die Vorderkante des Wäschestückes überwachenden Fotozelle angesteuert wird, einen Luftstrahl gegen die auslaufenden Wäschestücke und verhindert so, daß diese vom Tuch 7 mit nach oben genommen werden.At the exit of the second trough 3, the pneumatic scraper 13, which is controlled by a photo cell monitoring the front edge of the item of laundry, directs an air jet against the items of laundry which are running out and thus prevents them from being carried upwards by the cloth 7.

Die Position der Ränder (Kanten) des Tuches 7 wird, wie erwähnt, von mindestens einer Fotozelle überwacht, die an irgendeiner geeigneten Stelle am Wege des Tuches angeordnet sein kann. Solange das Tuch auf der Walze 5, 6 geradeaus läuft, also sich seitlich nicht versetzt, sind die Kolben der Zylinder 10 gleich weit ausgefahren ; die Achse der Rolle 9 steht waagerecht und die Rolle 9 übt auf das Tuch 7 einen gleichmäßigen, nach unten gerichteten Druck aus. Der Pendelbalken 8 arbeitet so ausschließlich als Spanneinrichtung für das Tuch 7.As mentioned, the position of the edges (edges) of the cloth 7 is monitored by at least one photocell, which can be arranged at any suitable location along the path of the cloth. As long as the cloth on the roller 5, 6 runs straight, ie not laterally offset, the pistons of the cylinders 10 are extended to the same extent; the axis of the roller 9 is horizontal and the roller 9 exerts a uniform, downward pressure on the cloth 7. The pendulum beam 8 thus works exclusively as a tensioning device for the cloth 7.

Wenn die Fotozelle feststellt, daß das Tuch 7 auf den Walzen 5, 6 in der einen oder anderen Richtung seitlich auswandert, gibt sie ein entsprechendes Signal ab. Dieses wird von einer entsprechenden, einfachen Steuerelektronik so verarbeitet, daß einer der beiden Zylinder 10 seinen Kolben weiter ausfährt als der andere. Die Rolle 9, deren Achse nunmehr gegen die Horizontale verkippt ist, übt jetzt einen über die Querrichtung des Tuches 7 ungleichmäßigen Druck aus, spannt dieses also ungleichmäßig. Hierdurch wird das Tuch 7 wieder in seine korrekte Position zurückgeführt.If the photocell detects that the cloth 7 migrates laterally on the rollers 5, 6 in one direction or the other, it emits a corresponding signal. This is processed by a corresponding, simple control electronics so that one of the two cylinders 10 extends its piston further than the other. The roller 9, the axis of which is now tilted against the horizontal, now exerts an uneven pressure across the transverse direction of the cloth 7, that is, it tensions it unevenly. As a result, the cloth 7 is returned to its correct position.

Bei einem zweiten, nicht dargestellten Ausführungsbeispiel wird eine Geradlaufeinrichtung verwendet, wie sie aus der Textilindustrie bekannt ist. Diese umfaßt ein Walzenpaar, durch welches das Tuch 7 (nicht notwendig auf der gesamten Breite) hindurchgeführt wird. Dieses Walzenpaar (oder mindestens eine Walze des Paares) läßt sich nun, wiederum durch eine Fotozelle gesteuert, in der Ebene des Tuches so verschwenken, daß es aus der neutralen Stellung, in welcher die Walzenachse(n) einen Winkel von 90° mit der Bewegungsrichtung des Tuches einschließt, in eine Stellung gelangt, in der die Walzenachse(n) einen stumpfen oder spitzen Winkel mit der Bewegungsrichtung des Tuches 7 einschließt. Auf diese Weise wird auf das Tuch ein Zug senkrecht zur Bewegungsrichtung ausgeübt, der das Tuch 7 wieder in die richtige Position zurückführt.In a second embodiment, not shown, a straight-running device is used, as is known from the textile industry. This comprises a pair of rollers through which the cloth 7 (not necessarily over the entire width) is passed. This pair of rollers (or at least one roller of the pair) can now, again controlled by a photocell, be pivoted in the plane of the cloth so that it is from the neutral position in which the roller axis (s) forms an angle of 90 ° with the direction of movement of the cloth, comes into a position in which the roller axis (s) encloses an obtuse or acute angle with the direction of movement of the cloth 7. In this way, a pull is exerted on the cloth perpendicular to the direction of movement, which pulls the cloth 7 back into the correct position.
