Definitions
- the invention relates to a defect for drying and / or flattening textiles, consisting of a heated cylinder to which the textiles are brought into contact by means of a belt, the belt and cylinder surface moving at different speeds.
- a conventional flatwork ironer with a roller diameter of 1000 mm which consists of two units in a row and has a flat path of around three meters, has a running speed of approx. 20 m / min. an installed drive power of approx. 7.5 KW.
- US Pat. No. 3,634,956 also describes a defect in which the circumferential speed from cylinder to belt should preferably be the same, but a relative speed between the two is indicated as possible. This is a defect with a single cylinder and a belt that wraps around this cylinder almost completely. In any case, the throughput speed of the laundry should be determined by the speed of the belt, i.e. it is not thought of making the cylinder run faster than the belt.
- the invention is based on the object, by means of a heated cylinder surface over which the textiles are guided, to flatten them with the lowest possible drive energy with good running-in behavior and to dry them to the required extent.
- An endless vapor-permeable belt 2 is guided over the heated cylinder 1 by means of the various guide rollers 3 in such a way that the largest possible wrap angle of the cylinder 1 takes place.
- the laundry is placed on the central horizontal part 4 of the belt and passed through the belt into the gap between the belt and the cylinder.
- the lower tip 5 of the laundry stripper 6 serves to introduce the laundry into the entry point.
- the laundry is moved away from the belt 2 at the speed Cg, while the cylinder surface moves at the speed Cz.
- the desired speed difference can be done by appropriate selection of the gear ratio of the drive roller 3 'for the belt on the cylinder, for. B. by appropriate choice of the number of teeth of the gears 7 and 8th
- the pressure of the belt against the cylinder is not the same over the entire wrap distance.
- the entry arrest should be brought about by the faster-running cylinder.
- the drive roller 3 ' is therefore expediently designed as a manual transmission.
- a circulation speed of the cylinder surface of the cylinder time is sufficient for the contact time required for drying about 25 m / min. Because of the relative speed between the belt and Cg and the cylinder surface Cz, which is only about 10%, ie Cg - 0.9 Cz, the ironing according to the invention with the same output of laundry items per unit of time is only about a tenth of the drive energy compared to that previously used Trough defects required, namely at 25 m / min. only about 0.75 KW.
- the large wrap angle compared to conventional trough ironers makes it possible to manage with half the number of ironer units - it is generally sufficient to have one unit - which has an advantageous effect in terms of space and manufacturing costs.
Description
Die Erfindung betrifft eine Mangel zum Trocknen und/oder Plätten von Textilien, bestehend aus einem beheizten Zylinder, an welchen die Textilien mittels eines Gurtes zur Anlage gebracht werden, wobei Gurt und Zylinderoberfläche sich mit unterschiedlicher Geschwindigkeit bewegen.The invention relates to a defect for drying and / or flattening textiles, consisting of a heated cylinder to which the textiles are brought into contact by means of a belt, the belt and cylinder surface moving at different speeds.
Es ist heute allgemein üblich, die Wäsche in einer Muldenmangel zu glätten, indem eine sich drehende textilbewickelte Walze das Wäschestück, über die feststehende geschliffene, und beheizte Plättfläche einer Mulde unter dem erforderlichen Anpreßdruck über den ganzen Plättweg bewegt. Wegen der langen Reibfläche bedingt eine solche Muldenmangel einen hohen Leistungsbedarf für den Antrieb. Eine herkömmliche Muldenmangel mit 1000 mm Walzendurchmesser, die aus zwei hintereinanderliegenden Einheiten besteht und einen Plättweg von rund drei Metern aufweist, hat bei einer Laufgeschwindigkeit von ca. 20 m/min. eine installierte Antriebsleistung von ca. 7,5 KW.It is now common practice to smooth the laundry in a trough defect by a rotating textile-wound roller moving the item of laundry over the fixed, ground and heated flat surface of a trough under the required contact pressure over the entire path of the board. Because of the long friction surface, such a lack of troughs requires a high amount of power for the drive. A conventional flatwork ironer with a roller diameter of 1000 mm, which consists of two units in a row and has a flat path of around three meters, has a running speed of approx. 20 m / min. an installed drive power of approx. 7.5 KW.
Es ist auch bekannt (DE-A-3 209 404) zum Vortrocknen der Textilien, diese mittels eines endlosen umlaufenden Bandes über die Mantelfläche eines beheizten und drehbar gelagerten Vortrockenzylinders zu führen.It is also known (DE-A-3 209 404) for predrying the textiles to guide them by means of an endless circulating belt over the outer surface of a heated and rotatably mounted predrying cylinder.
Gurt und Zylinder laufen mit gleicher Geschwindigkeit, so daß lediglich eine Trocknung der Textilien nicht aber ein Plätten erfolgen kann. Der Plättvorgang findet in den nachgeschalteteten Mangelmulden statt.Belt and cylinder run at the same speed, so that only drying of the textiles but not flattening can take place. The flattening process takes place in the downstream troughs.
Um ein vollkommen glattes Anlegen des Mangelgurtes zu gewährleisten, ist es durch die DE-OS-1 812 655 bekannt, den Gurt mit einer Geschwindigkeit umlaufen zu lassen, die größer als die Drehgeschwindigkeit der Mangelwalze ist. Hierdurch soll das Mangelgut einer Zug- und Spannwirkung unterzogen werden, welche das glatte Anlegen sicherstellt. Diese Maßnahme ist einleuchtend, hat aber den Nachteil, daß beim Einführen des Mangelgutes wegen des langsamer als der Gurt laufenden Zylinders die Wäsche anstößt und die deshalb nicht glatt liegenden Wäsche zwischen Zylinder und Gurt gelangt. Die relative Geschwindigkeit zwischen Gurt und Zylinder hat den Vorteil, daß zwecks Glättung der Wäsche diese nicht über die volle zum Trocknen notwendige Plättfläche unter Druck gezogen werden muß. Zum Trocknen ist nur Kontaktzeit erforderlich und diese steht auf dem Transportweg ausreichend zur Verfügung.In order to ensure a completely smooth application of the ironing belt, it is known from DE-OS-1 812 655 to let the belt rotate at a speed which is greater than the rotational speed of the ironing roller. This is intended to subject the deficient goods to tensile and tension effects, which ensure smooth application. This measure is obvious, but has the disadvantage that when the defective goods are introduced, the laundry bumps due to the cylinder running slower than the belt and the laundry, which is therefore not lying flat, gets between the cylinder and the belt. The relative speed between the belt and the cylinder has the advantage that, in order to smooth the laundry, it does not have to be pulled under pressure over the full flat surface necessary for drying. Only contact time is required for drying and this is sufficiently available on the transport route.
Auch die US-PS-3 634 956 beschreibt eine Mangel, bei welcher zwar vorzugsweise die Umfangsgeschwindigkeit von Zylinder zu Gurt gleich sein soll, aber eine Relativgeschwindigkeit zwischen beiden als möglich angedeutet wird. Dabei handelt es sich um eine Mangel mit einem einzigen Zylinder und einem diesen Zylinder fast vollständig umschlingenden Gurt. In jedem Fall soll aber die Durchlaufgeschwindigkeit der Wäsche von der Geschwindigkeit des Gurtes bestimmt werden, d.h. es wird nicht daran gedacht den Zylinder schneller als den Gurt laufen zu lassen.US Pat. No. 3,634,956 also describes a defect in which the circumferential speed from cylinder to belt should preferably be the same, but a relative speed between the two is indicated as possible. This is a defect with a single cylinder and a belt that wraps around this cylinder almost completely. In any case, the throughput speed of the laundry should be determined by the speed of the belt, i.e. it is not thought of making the cylinder run faster than the belt.
Der Erfindung liegt die Aufgabe zugrunde, mittels einer beheizten Zylinderfläche, über welche die Textilien geführt werden, diese mit möglichst geringer Antriebsenergie bei gutem Einlaufverhalten einwandfrei zu Plätten und auf das erforderliche Maß zu Trocknen.The invention is based on the object, by means of a heated cylinder surface over which the textiles are guided, to flatten them with the lowest possible drive energy with good running-in behavior and to dry them to the required extent.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, die Geschwindigkeit der Zylinderoberfläche größer als die Gurtgeschwindigkeit zu wählen.To achieve this object, it is proposed according to the invention to choose the speed of the cylinder surface greater than the belt speed.
Hierdurch tritt der überraschende Effekt auf, daß ein optimales Einlaufverhalten erzielt wird, denn das sich dem rotierenden Zylinder nähernde Wäschestück wird an seiner Kante vom Zylinder erfaßt und durch die schnellere Umfangsgeschwindigkeit des Zylinders glatt gestrichen bevor der Gurtdruck wirksam wird.This results in the surprising effect that an optimal running-in behavior is achieved, because the laundry item approaching the rotating cylinder is gripped by the cylinder at its edge and smoothed out by the faster peripheral speed of the cylinder before the belt pressure takes effect.
Ein merklicher negativer Einfluß auf das Gesamtergebnis trotz verändertem Druckverlauf über die gesamte Länge konnte nicht festgestellt werden.A noticeable negative influence on the overall result despite the change in pressure over the entire length could not be determined.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt.In the drawing, the invention is illustrated using an exemplary embodiment.
Über den beheizten Zylinder 1 wird ein endloser dampfdurchlässigen Gurt 2 mittels der verschiedenen Führungsrollen 3 so geführt, daß ein möglichst großer Umschlingungswinkel des Zylinders 1 erfolgt. Die Wäsche wird auf dem mittleren horizontalen Teil 4 des Gurtes aufgelegt und durch den Gurt in den Spalt zwischen Gurt und Zylinder geführt. Die untere Spitze 5 des Wäscheabstreifers 6 dient der Einführung der Wäsche in die Einlaufstelle.An endless vapor-
Mit der Geschwindigkeit Cg wird die Wäsche vom Gurt 2 fortbewegt, während die Zylinderoberfläche sich mit der Geschwindigkeit Cz bewegt. Die jeweils gewünschte Geschwindigkeitsdifferenz kann durch entsprechende Wahl des Übersetzungsverhältnisses von der Antriebsrolle 3' für den Gurt auf den Zylinder erfolgen, z. B. durch entsprechende Wahl der Zähnezahlen der Zahnräder 7 und 8.The laundry is moved away from the
Die Andrückkraft des Gurtes an den Zylinder ist nicht über den ganzen Umschlingungsweg gleich.The pressure of the belt against the cylinder is not the same over the entire wrap distance.
Ob die Andrückkraft des Gurtes am Auslaufende oder an der Einführungsstelle der Wäsche am größten ist oder umgekehrt, hängt davon ab, welche der beiden sich relativ zueinander bewegenden Teile (Gurt bzw. Zylinder) schneller läuft. Der höhere Andruck am Ende, d.h., zur Auslaufstelle hin, ist zwar für den Plättvorgang günstig, aber für das Einlaufverhaften ungünstig. Gemäß der Erfindung soll aber das Einlaufverhaften durch den schneller laufenden Zylinder bewirkt werden. Je nach Wäscheart kann es aber zweckmäßig sein, auch einmal den Gurt am schnellsten laufen zu lassen. Die Antriebsrolle 3' ist deshalb zweckmäßig als Schaltgetriebe ausgebildet.Whether the pressure of the belt is greatest at the outlet end or at the point of insertion of the laundry or vice versa depends on which of the two parts moving relative to each other (belt or cylinder) runs faster. The higher pressure at the end, i.e. towards the outlet, is good for the plating process, but unfavorable for arresting the inlet. According to the invention, however, the entry arrest should be brought about by the faster-running cylinder. Depending on the type of laundry, it may be advisable to run the belt as quickly as possible. The drive roller 3 'is therefore expediently designed as a manual transmission.
Bei einem gesamten Plättweg von etwa drei Metern, was bei einem günstigen Umschlingungswinkel von etwa 290° etwa einen Zylinderdurchmesser von 1,20 m entspricht reicht für die zum Trocknen notwendige Kontaktzeit eine Umlaufgeschwindigkeit der Zyiinderoberfiäche von etwa 25 m/min aus. Wegen der relativen Geschwindigkeit zwischen Gurt und Cg und Zylinderoberfläche Cz, welche etwa nur 10 % beträgt, d.h. Cg - 0,9 Cz, wird für die erfindungsgemäße Mangel bei gleichem Ausstoß an Wäscheteilen pro Zeiteinheit auch nur etwa ein Zehntel der Antriebsenergie gegenüber den bisher üblichen Muldenmangeln benötigt, nämlich bei 25 m/min. nur noch ca. 0,75 KW.With an entire flat path of about three meters, which corresponds to a cylinder diameter of 1.20 m with a favorable wrap angle of about 290 °, a circulation speed of the cylinder surface of the cylinder time is sufficient for the contact time required for drying about 25 m / min. Because of the relative speed between the belt and Cg and the cylinder surface Cz, which is only about 10%, ie Cg - 0.9 Cz, the ironing according to the invention with the same output of laundry items per unit of time is only about a tenth of the drive energy compared to that previously used Trough defects required, namely at 25 m / min. only about 0.75 KW.
Der große Umschlingungswinkel gegenüber den herkömmlichen Muldenmangeln macht es möglich, daß man mit der halben Anzahl an Mangeleinheiten auskommt - es reicht im allgemeinen eine einzige Einheit aus - was sich im Platzbedarf und den Herstellkosten vorteilhaft auswirkt.The large wrap angle compared to conventional trough ironers makes it possible to manage with half the number of ironer units - it is generally sufficient to have one unit - which has an advantageous effect in terms of space and manufacturing costs.
