Abstract

The press container of a wash press sits on a porous press plate. Because of the high press pressure of the press piston head the fabrics of the wash are partially forced into the holes of the press plate. In order to remove the pressed wash safely from the press plate, the pressed wash is raised somewhat from the press plate when the press container and press piston are simultaneously raised, first into a middle position in which the press piston head remains, while the press container is raised further. The wash loosened in this way can be safely slid laterally from the press plate.

Description

Die Erfindung betrifft ein Verfahren zum Entfernen eines entwässerten Wäschepostens aus dem Preßbehälter einer Kolbenpresse.The invention relates to a method for removing a dewatered laundry item from the press container of a piston press.

Zum Entwässern von Wäscheposten ist es bekannt, über den Wäscheposten einen glockenförmigen Membranträger zu stülpen und die Membran mittels eines Druckmittels zu beaufschlagen. In der DE-PS 2 852 923 wird eine solche Presse mit einem in den Preßboden absenkbaren Einfüllrahmen beschrieben. Nach dem Anheben des Membranträgers und des Einfüllrahmens liegt der ausgepreßte Wäscheposten frei auf dem gelochten Preßboden und kann von diesem abgeschoben werden. Bei dem hohen Preßdruck ist nicht zu vermeiden, daß sich Gewebeteile fest in den Lochungen des Preßbodens halten und deshalb beim Wegschieben des Wäschepostens Wäscheschäden auftreten können. Ähnliche Probleme treten auf, wenn eine Kolbenpresse verwendet wird, wie sie beispielsweise in der DE-OS 2 602 845 beschrieben ist. Auch hier bleibt der ausgepreßte Wäscheposten aus der Preßlage auf dem Preßboden liegen, indem zunächst der Preßbehälter und anschließend das Preßhaupt angehoben wird.For dewatering laundry items, it is known to place a bell-shaped membrane support over the laundry items and to apply pressure to the membrane. In DE-PS 2 852 923, such a press is described with a filling frame that can be lowered into the press floor. After lifting the membrane support and the filling frame, the pressed laundry item is free on the perforated press base and can be pushed off it. With the high pressing pressure, it cannot be avoided that fabric parts are held firmly in the perforations of the pressing base and therefore laundry damage can occur when the laundry item is pushed away. Similar problems occur when a piston press is used, as described for example in DE-OS 2 602 845. Here, too, the pressed laundry item remains from the press layer on the press base by first lifting the press container and then the press head.

Aufgabe der Erfindung ist es, den ausgepreßten Wäscheposten möglichst schonend aus der Kolbenpresse zu entleeren und in die nachfolgende Station, z. B. einen Trommeltrockner zu befördern. Zur Lösung dieser Aufgabe werden die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen. Der ausgepreßte Wäscheposten wird auf diese Weise zunächst aus den Bohrungen der unteren Preßplatte angehoben, so daß ein schonendes lockern und anschließend ein gefahrloses seitliches Wegschieben des aufgelockerten Wäschekuchens möglich ist. In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt. Es zeigen:

  • Fig. 1 Stellung von Preßbehälter und Preßkolben am Ende der Preßzeit
  • Fig. 2 Stellung zum Zeitpunkt des Anstoßens des Wäschepostens
  • Fig. 3 Ausgangsstellung.
The object of the invention is to empty the pressed laundry items as gently as possible from the piston press and into the subsequent station, e.g. B. to convey a tumble dryer. To achieve this object, the features specified in claim 1 are proposed. In this way, the pressed laundry item is first lifted out of the holes in the lower press plate, so that gentle loosening and then safe lateral pushing of the loosened laundry cake is possible. In the drawing, the invention is illustrated using an exemplary embodiment. Show it:
  • Fig. 1 position of the press container and plunger at the end of the pressing time
  • Fig. 2 position at the time of initiation of the laundry item
  • Fig. 3 starting position.

Auf die untere Preßplatte 1 mit den Lochungen 2 zum Ablaufen des Preßwassers ist der Preßbehälter 3 aufgesetzt. Nachdem die Wäsche 4 aus der vorgeschalteten Waschmaschine in den Preßbehälter 3 gefüllt worden ist, wird von oben das hydraulisch angetriebene Preßhaupt 5 mit der elastischen Auflage 6 z. B. einem wassergefüllten Kissen eingefahren und die Wäsche bei einem Druck von etwa 30 bar ausgepreßt. Die Fig. 1 zeigt die Stellung am Ende eines solchen Preßvorganges. Nun kommt es darauf an, den Wäschekuchen von der Preßplatte 1 ohne Beschädigung des Gewebes der Wäsche zu entfernen. Hierzu werden der Preßbehälter 3 und das Preßhaupt 5 gleichsinnig hochgefahren, wie die beiden Pfeile in Fig. 1 andeuten sollen. Der Wäschekuchen wird somit entgegen der Preßrichtung schonend von der Preßplatte 1 abgehoben. Sobald das Preßhaupt bei der Aufwärtsbewegung eine Mittelstellung erreicht, bleibt es durch eine entsprechende Auslegung der Steuerung stehen, während der Preßbehälter weiter bis in Endstellung hochfährt. Der den Preßbehälter betätigende Antrieb 7 ist lediglich symbolisch angedeutet. Die Folge ist, daß der Wäschekuchen aus dem Preßbehälter 3 ausgestoßen wird, locker auf die Preßplatte 1 herunterfällt und von dort gefahrlos durch einen Schieber seitlich ausgestoßen werden kann. Anschließend werden das Preßhaupt 5 und der Preßbehälter 3 wieder in Ausgangsstellung (Fig. 3) gefahren und eine neue Füllung kann erfolgen.The press container 3 is placed on the lower press plate 1 with the perforations 2 for draining the press water. After the laundry 4 has been filled from the upstream washing machine into the press container 3, the hydraulically driven press head 5 with the elastic pad 6 is z. B. retracted a water-filled pillow and pressed the laundry at a pressure of about 30 bar. Fig. 1 shows the position at the end of such a pressing process. Now it is important to remove the laundry cake from the press plate 1 without damaging the fabric of the laundry. For this purpose, the press container 3 and the press head 5 are raised in the same direction, as the two arrows in Fig. 1 are intended to indicate. The laundry cake is thus carefully lifted from the press plate 1 against the pressing direction. As soon as the press head reaches a central position during the upward movement, it is stopped by an appropriate design of the control, while the press container continues to move up to the end position. The drive 7 actuating the press container is only indicated symbolically. The result is that the laundry cake is ejected from the press container 3, falls loosely onto the press plate 1 and can be safely ejected laterally from there by a slide. Then the press head 5 and the press container 3 are moved back to the starting position (FIG. 3) and a new filling can take place.
