Description

Die vorliegende Erfindung betrifft eine Bügelmangel mit wenigstens einer Anordnung, bestehend aus beheizter, gestellfester Mulde und rotierend angetriebener, in Ruhestellung abhebbarer Anpresswalze, welche Mulde als konkave kreiszylindrische Wölbung in einem zylindrischen Hohlkörper mit in sich geschlossener Leitlinie ausgebildet ist und die übrige Aussenwand des Hohlkörpers mit Ausnahme von Partien zu dessen Befestigung und zur Zu- und Wegführung von Leitungen für ein Wärmemedium als beheizte Kontaktfläche für die Mangelware ausgebildet ist.The present invention relates to a ironing ironer with at least one arrangement consisting of a heated, frame-fixed trough and a rotationally driven pressure roller which can be raised in the rest position, which trough is designed as a concave circular-cylindrical curvature in a cylindrical hollow body with a self-contained guideline and the rest of the outer wall of the hollow body Exception of parts for its attachment and for the supply and removal of lines for a heating medium is designed as a heated contact surface for the scarce goods.

In der Zeitschrift «Wäscherei-technik und -chemie», Heft 9, 19. Jahrgang, 1966, Seiten 532-540, wurden Untersuchungen an einer Muldenmangel veröffentlicht. Darin werden als Aufgaben für eine Mangel die Verdampfung der Restfeuchtigkeit nach dem Entwässern der Wäsche und das Glätten und Fixieren der Gewebeoberfläche angeführt. Es wurde als Resultat gefunden, dass

  • 1. die Wäschefeuchtigkeit nicht linear mit der Durchgabezahl abnimmt;
  • 2. die Durchlaufgeschwindigkeit bei festgelegter Muldengrösse und Wäschefeuchtigkeit die Kontaktzeit des Wäschestückes und damit die Verdampfungsrate bestimmt;
  • 3. die Temperatur am Gewebe in erster Linie vom Feuchtigkeitsgehalt der Wäsche abhängt, und
  • 4. die abgesaugte Luftmenge die Verdampfungsleistung verhältnismässig wenig beeinflusst, dass jedoch zur Vermeidung von Kondenswasseransammlung in der Bewicklung auf eine Absaugung, deren Stärke auf die Verdampfungsleistung abgestimmt sein sollte, nicht verzichtet werden kann.
In the magazine "Laundry technology and chemistry", Issue 9, 19th year, 1966, pages 532-540, studies on a lack of troughs were published. It lists the evaporation of the residual moisture after dewatering the laundry and the smoothing and fixing of the fabric surface as tasks for a defect. As a result, it was found that
  • 1. the laundry moisture does not decrease linearly with the throughput number;
  • 2. the throughput speed with a defined trough size and laundry moisture determines the contact time of the item of laundry and thus the evaporation rate;
  • 3. The temperature on the fabric depends primarily on the moisture content of the laundry, and
  • 4. The amount of air sucked out influences the evaporation performance relatively little, but that in order to avoid the accumulation of condensate in the winding, suction, the strength of which should be matched to the evaporation performance, cannot be dispensed with.

Diese Veröffentlichung zeigt auf, dass bei jeder Mangel ein Kompromiss zwischen sich widersprechenden Bedingungen anzustreben ist. Während die Trocknung der Wäsche eine Folge der Kontaktzeit ist, sollte die Kontaktlänge zwischen Walze und Mulde möglichst lang sein. Da jedoch die Bewicklung der Walze die Feuchtigkeit aufnimmt, muss sie von genügend Luft durchströmt sein, um Kondenswasser zu vermeiden. Dazu kommt noch, dass die Kontaktlänge nur gerade so lange sein darf, dass die Wäsche am Ende trocken ist, weil ein längerer Kontakt die Wäsche überhitzt und damit das Gewebe übertrocknet würde.This publication shows that a compromise between contradicting conditions should be sought for every defect. While the drying of the laundry is a consequence of the contact time, the contact length between the roller and the trough should be as long as possible. However, since the winding of the roller absorbs the moisture, enough air must flow through it to avoid condensation. In addition, the contact length may only be so long that the laundry is dry at the end, because prolonged contact overheats the laundry and thus the fabric would be over-dried.

Anderseits gehen die Bestrebungen darauf hinaus, möglichst keine Wärme der Mulde zu verlieren und die Flächen des Heizkörpers neben der Mulde zum Trocknen der Wäsche zu benützen.On the other hand, efforts are aimed at not losing any heat from the trough and using the surfaces of the radiator next to the trough to dry the laundry.

In der US-A-2488020 ist ein Ausführungsbeispiel einer Bügelmangel beschrieben. Der beheizte Muldenkörper hat die Form eines Kleeblattes mit drei konkaven Mulden und gerundeten Übergangspartien zwischen den Mulden. In jeder Mulde ist eine gegen die Mulde gepresste Walze vorhanden, und bis auf eine gerundete Übergangspartie ist der Muldenkörper von Transportbändern umwickelt. Ein Trockentuch ist anderseits zwischen die Walzen und die Transportbänder gelegt. Die Wäsche wird somit zwischen diesem Trockentuch und den Transportbändern um den Muldenkörper herum geführt. Damit wird die grösste mögliche Wärmemenge vom Muldenkörper auf die Wäsche übertragen. Das Trockentuch wird ebenfalls erwärmt und kann die Feuchtigkeit aus der Wäsche aufnehmen; es besteht jedoch keine Möglichkeit, dass das Trockentuch selbst getrocknet werden kann, ausser auf dem Rücktransportweg von der Wäscheausgabe zur Wäscheeingabe und damit muss um diese Bügelmangel herum ein starker Luftzug herrschen, der dieses Tuch trocknen kann, wodurch die Umweltbedingungen für Bedienungspersonal denkbar schlecht sind.In US-A-2488020 an embodiment of a ironing iron is described. The heated bowl body has the shape of a cloverleaf with three concave bowls and rounded transition parts between the bowls. In each trough there is a roller pressed against the trough and, apart from a rounded transition section, the trough body is wrapped in conveyor belts. On the other hand, a drying cloth is placed between the rollers and the conveyor belts. The laundry is thus guided around this body between this drying cloth and the conveyor belts. This transfers the largest possible amount of heat from the body of the body to the laundry. The drying cloth is also heated and can absorb the moisture from the laundry; However, there is no possibility that the drying cloth can be dried itself, except on the return route from the laundry dispenser to the laundry input and therefore there must be a strong draft around this lack of hangers, which can dry this cloth, making the environmental conditions for operating personnel extremely bad.

Üblicherweise wird der zur Trocknung der Bewicklung der Walzen benötigte Luftstrom durch die Walze abgesaugt, wie dies auch schon in der BE-A-431 595 beschrieben wurde, nur wird dort in fälschlicher Betrachtungsweise der Luftstrom verringert, um wenig Wärme abzuleiten. Die abgesaugte Luftmenge muss jedoch gemäss der o.a. Zeitschrift in der Grössenordnung von 100-200 m3/h je m2 freie Walzenfläche betragen, obwohl dieser Luftstrom auf die Verdampfungsleistung der Mangel keinen Einfluss hat und nur zurTrocknung der Walzenbeschichtung dient.Usually, the air flow required to dry the winding of the rolls is sucked off by the roll, as has already been described in BE-A-431 595, only the air flow is incorrectly reduced there in order to dissipate little heat. According to the above-mentioned magazine, however, the amount of air extracted must be in the order of 100-200 m 3 / h per m 2 of free roll area, although this air flow has no influence on the evaporation performance of the defect and only serves to dry the roll coating.

Gemäss dem Vorschlag in der GB-A-962486 sind zwei Mulden horizontal hintereinander angeordnet. Bei der ersten Mulde wird die Walze noch mit einem Heizelement in Form einer weiteren, oben liegenden Mulde umfasst, um die nach unten abgestrahlte Wärme zu kompensieren, und die Mangelware wird vor deren Zuführung zur zweiten Mulde noch um dieses zusätzliche Element herumgeführt. Durch dieses Element wird aber gerade der Luftdurchtritt bei der ersten und daher nassen Walze verringert und trotz guter Wärmeausnützung kann die Bespannung der Walze nicht mit der nötigen Luft durchsetzt werden, um die Feuchtigkeit aus der Wäsche aufzunehmen.According to the proposal in GB-A-962486, two troughs are arranged horizontally one behind the other. In the first trough, the roller is also covered with a heating element in the form of a further trough lying at the top in order to compensate for the heat radiated downwards, and the scarce goods are guided around this additional element before being fed to the second trough. With this element, however, the passage of air in the first and therefore wet roller is reduced and, despite good heat utilization, the covering of the roller cannot be permeated with the necessary air to absorb the moisture from the laundry.

Es ist eine Aufgabe der Erfindung, bei einer Bügelmangel die Wärmeabgabe durch den Muldenkörper auf die Mangelware zu optimieren und für die Trockenhaltung der Walzen genügend freie Oberfläche zu schaffen, um den notwendigen Luftdurchsatz zu ermöglichen. Zudem soll die Anordnung von Mulde und Walze derart sein, dass bei Energieausfall die Walze von der Mulde abgehoben werden kann, um die Mangelware nicht zu übertrocknen.It is an object of the invention to optimize the heat dissipation through the trough body onto the scarce goods when there is a lack of a stirrup and to provide enough free surface for keeping the rollers dry in order to enable the necessary air throughput. In addition, the arrangement of trough and roller should be such that the roller can be lifted off the trough in the event of a power failure in order not to overdry the scarce goods.

Erfindungsgemäss wird dies dadurch erreicht, dass bei einer eingangs beschriebenen Bügelmangel die Wölbung wenigstens angenähert einen axial geschnittenen Halbzylinder darstellt, von dem die die Zylinderfläche begrenzenden Mantellinien eine mit einer Vertikalebene einen Winkel zwischen 0° und 30° einschliessende Muldenebene bestimmen und die Walzenachse im Abstand von der Muldenebene und auf deren von der Mulde abgewandten Seite angeordnet ist.This is achieved according to the invention in that, in the case of a shortage of brackets described at the outset, the curvature at least approximately represents an axially cut half-cylinder, of which the surface lines delimiting the cylinder surface are one with a vertical plane Determine the trough plane including the angle between 0 ° and 30 ° and the roller axis is arranged at a distance from the trough plane and on its side facing away from the trough.

Eine Bügelmangel mit dem Merkmal, dass die die Mulde begrenzenden Mantellinien eine mit der Vertikalebene einen Winkel zwischen 0° und 30° einschliessende Muldenebene bestimmen, ist an sich aus der GB-A-689639 bekannt. Nachfolgend wird die Erfindung anhand einiger Ausführungsbeispiele, die durch Fig. 1 bis 3 schematisch im Aufriss dargestellt sind, erläutert. Dabei zeigt:

  • Fig. 1 eine Einwalzenmangel,
  • Fig. eine Zweiwalzenmangel und
  • Fig. eine Vierwalzenmangel.
A shortage of stirrups with the feature that the shell lines delimiting the trough determine a trough plane including an angle with the vertical plane of between 0 ° and 30 ° is known per se from GB-A-689639. The invention is explained below on the basis of a few exemplary embodiments, which are schematically represented in elevation by FIGS. 1 to 3. It shows:
  • 1 is a shortage of rollers,
  • Fig. A two-roll mangle and
  • Fig. A four-roll mangle.

Jede dieser Anordnungen zeigt andeutungsweise ein Maschinenbett 10 mit den benötigten und jedem Fachmann bekannten Bedienungsgeräten, wie Antrieb für die Walzen, Steuermittel für die Steuerung der Anpressung der Walzen in die Mulden, die hier mit einem Druckerzeuger 20 angedeutet ist und den zugehörigen Druckleitungen 21 und Zylinder-Kolbenanordnungen 23, die auf Lagerungshebel 24-27 wirken, sowie die Wärmequellen zum Erwärmen der Mulden. Bei allen drei Varianten sind zudem noch Transportbänder 28, 29 für die Zuführung der Wäsche zu den Mangeln und die Wegführung von den Mangeln angedeutet. Das Gehäuse 11 ist beispielsweise die hinten liegende Wandung des Aufbaus für die Antriebsmittel, Über- oder Untersetzergetriebe und ähnlichem, wie sie für den Antrieb der Walzen selbst, die Führung für die Wäschestücke auf dem Weg von einer Mulde in die andere mittels Förderbänder, Abstreifer und ähnlichem, wie auch jedem Fachmann bekannt ist, benötigt werden.Each of these arrangements shows a hint of a machine bed 10 with the necessary operating devices known to a person skilled in the art, such as drive for the rolls, control means for controlling the pressing of the rolls into the troughs, which is indicated here with a pressure generator 20 and the associated pressure lines 21 and cylinders Piston assemblies 23, which act on bearing levers 24-27, and the heat sources for heating the troughs. In all three variants, conveyor belts 28, 29 for feeding the laundry to the ironers and guiding them away from the ironers are also indicated. The housing 11 is, for example, the rear wall of the structure for the drive means, step-up or step-down gear and the like, as it is for the drive of the rollers themselves, the guide for the laundry items on the way from one trough to the other by means of conveyor belts, wipers and Similar, as is known to any person skilled in the art.

Der Weg der Wäschestücke ist in allen drei Beispielen durch eine strichpunktierte oder Phantomlinie W dargestellt.The path of the laundry items is shown in all three examples by a dash-dotted or phantom line W.

Gemäss dem erfindungsgemässen Vorschlag bildet die Mulde eine kreiszylindrische Vertiefung in einem Zylinderkörper, dessen Leitlinie bei einer Einwalzenmangel gemäss Fig. 1 aus einem Halbkreisbogen 30 und einem Viertelkreisbogen 31, mit verschobenen Zentren, einem Verbindungshalbkreisbogen 32 sowie zwei rechtwinklig aufeinanderstehenden Geraden 33, 34 zusammengesetzt ist. Die Ebene, in der die Endkanten der Mulde liegen, schliesst mit einer senkrechten Ebene einen Winkel zwischen 0° und 30°, vorzugsweise 15° ein. Damit wird erreicht, dass die Walze durch die Mulde nicht unterstützt ist und somit durch entsprechende Halterung mit dem Hebel 24 bei wegfallendem Anpressdruck selbsttätig aus der Mulde herausfallen kann.According to the proposal according to the invention, the trough forms a circular-cylindrical depression in a cylinder body, the guideline of which, in the case of a single-roll shortage according to FIG. 1, is composed of a semicircular arc 30 and a quarter-circular arc 31, with shifted centers, a connecting semicircular arc 32 and two straight lines 33, 34 which are perpendicular to one another. The plane in which the end edges of the trough lie includes an angle between 0 ° and 30 °, preferably 15 °, with a vertical plane. This ensures that the roller is not supported by the trough and can therefore automatically fall out of the trough by means of a corresponding holder with the lever 24 when the contact pressure is eliminated.

Die Auflage bzw. der Weg W für die Wäschestücke führt somit über die gesamte Oberfläche des zylindrischen Hohlkörpers 12 mit Ausnahme der einen Fläche mit dem Leitlinienteil 34 hinweg, so dass die Wärmeabgabe von dieser ganzen, überstrichenen Oberfläche ausgenützt werden kann.The support or the path W for the laundry items thus leads over the entire surface of the cylindrical hollow body 12 with the exception of one surface with the guideline part 34, so that the heat emission from this entire, swept surface can be used.

In Fig. 2 sind zwei Walzen 14 und 15 vorhanden, die eine Verdoppelung der Anordnung nach Fig. 1 durch symmetrische Abbildung bezüglich einer vertikalen Ebene darstellen. Auch hier sind die Mulden 30a, b je ein Halbzylindermantel und die Verbindung der beiden Halbkreise in der Leitlinie ist ein Kreisbogen 16 beim Wäscheweg W und eine Gerade 17 für die Standfläche des Zylinders 13.In Fig. 2 there are two rollers 14 and 15, which represent a doubling of the arrangement of Fig. 1 by symmetrical imaging with respect to a vertical plane. Here, too, the troughs 30a, b are each a half-cylinder jacket and the connection of the two semicircles in the guideline is an arc 16 at the laundry path W and a straight line 17 for the footprint of the cylinder 13.

Die Anordnung nach Fig. 3 mit vier Walzen 14, 14a, 15,15a und vier Mulden 30a, 30b, 30c und 30d stellt wiederum eine Verdoppelung der Anordnung gemäss Fig. 2 dar, wobei die Anordnung gemäss Fig. 2 um eine horizontale Ebene als Symmetrieebene gespiegelt ist. Auch hier sind die obere links liegende Mulde 30c und die obere rechts liegende Mulde 30d mit einer gewölbten Fläche, die in der Leitlinie des zylindrischen Hohlkörpers 18 ein Kreisbogen 16 ist und die untere links liegende Mulde 30a und die untere rechts liegende Mulde 30b durch eine ebene Fläche, die sich auch wieder durch eine gerade Linie 17 darstellt, verbunden.The arrangement according to FIG. 3 with four rollers 14, 14a, 15, 15a and four troughs 30a, 30b, 30c and 30d in turn represents a doubling of the arrangement according to FIG. 2, the arrangement according to FIG. 2 being about a horizontal plane Plane of symmetry is mirrored. Here, too, are the upper left-hand trough 30c and the upper right-hand trough 30d with a curved surface, which is a circular arc 16 in the guideline of the cylindrical hollow body 18 and the lower left-hand trough 30a and the lower right-hand trough 30b through a flat surface Area, which is again represented by a straight line 17.

Allen diesen Ausführungsbeispielen ist gemeinsam, dass der Weg W für die Wäschestücke um den Heizkörper, d.h. den zylindrischen Hohlkörper, herumgeführt ist, so dass ausser bei der Standfläche, entsprechend dem geradlinigen Leitlinienteil 34, Fig. 1, bzw. 17, Fig. 2 und 3, keine Wärme verloren geht und praktisch die gesamte zugeführte Wärme zum Trocknen der Wäsche verwendet ist. Dadurch, dass die Mulden nicht «liegend», sondern «stehend», d.h. die Endgeraden der Mulden liegen wenigstens angenähert übereinander, angeordnet sind, kann der Raum bei Mehrwalzentrommeln stark verkleinert werden, so dass eine Luftabsaughaube für die Klimatisierung des Raumes auch etwa auf die Hälfte der sonst benötigten Fläche verkleinert werden kann.It is common to all these exemplary embodiments that the path W for the laundry items around the radiator, i.e. the cylindrical hollow body is guided around, so that no heat is lost except for the standing surface, corresponding to the straight-line guideline part 34, FIGS. 1 and 17, FIGS. 2 and 3, and practically all the heat supplied is used to dry the laundry . Because the troughs are not "lying" but "standing", i.e. the end straight lines of the troughs are at least approximately one above the other; if they are arranged, the space in multi-drum drums can be greatly reduced, so that an air extraction hood for the air conditioning of the space can also be reduced to about half the area otherwise required.

Ein weiterer Vorteil einer derartigen Anordnung zur Ausnützung der gesamten Wärme des Hohlkörpers mit der eingeformten Mulde zeigt sich bei der Einwalzenanordnung nach Fig. 1. Bisher war bei einer derart «stehend» angeordneten Mulde die Zuführung der Wäsche von vorne und oben; sie konnte dann vorn und unten wieder abgenommen werden. Bei einer «liegenden» Mulde ist die Zuführung vorn und die Abgabe hinten. Somit musste bisher je nachdem, ob der Käufer die Abgabe der Wäsche von der Mulde hinten oder vorn wünschte, eine besondere Konstruktion angeboten werden. Durch die vorgeschlagene Anordnung kann die Wäsche in beiden Fällen vorn zugeführt und je nachdem hinten weitergeführt oder durch eine einfache Führungsanordnung nach vorn, unterhalb der Zuführstelle, umgeleitet werden. Der Hersteller muss damit nicht mehr zwei verschiedene Einwalzenmangeln vorrätig haben, um alle Kundenwünsche zu befriedigen.A further advantage of such an arrangement for utilizing the entire heat of the hollow body with the molded-in trough can be seen in the single-roller arrangement according to FIG. 1. Up to now, the trough was arranged in such a "standing" manner that the laundry was fed from the front and from above; it could then be removed from the front and bottom. In the case of a “lying” trough, the feed is at the front and the discharge at the rear. Thus, depending on whether the buyer wanted the laundry to be returned from the trough at the rear or at the front, a special design had to be offered. In both cases, the proposed arrangement allows the laundry to be fed in at the front and, depending on the rear, to be carried forward or redirected to the front, below the feed point, by a simple guide arrangement. The manufacturer no longer has to have two different single-roll mangles in order to satisfy all customer requests.
