Description

Die Erfindung betrifft eine Vorrichtung zum Wechseln von Distanzelementen an einer Mehretagenpresse, die eine vertikal angeordnete Tragsäule mit den einzelnen Etagen der Presse zugeordneten Tragfingern für die Distanzelemente aufweist.The invention relates to a device for changing spacer elements on a multi-daylight press, which has a vertically arranged support column with support fingers for the spacer elements assigned to the individual levels of the press.

In Mehretagenpressen werden gleichzeitig mehrere Platten, z.B. Spanplatten oder dergleichen, gepreßt. Damit die Platten eine gleichmäßige und vorbestimmte Wandstärke erhalten, weden zwischen den einzelnen Etagen Distanzelemente angeordnet. Die Distanzelemente können plattenförmig, leistenförmig oder dergleichen ausgebildet sein. Sie werden in der Regel auf dafür vorbestimmte Bereiche der einzelnen Etagen aufgelegt und sind auswechselbar, damit Platten unterschiedlicher Stärke mit der Mehretagenpresse hergestellt werden können.Multiple plates, e.g. Chipboard or the like, pressed. So that the panels have a uniform and predetermined wall thickness, spacer elements are arranged between the individual floors. The spacer elements can be plate-shaped, strip-shaped or the like. They are usually placed on areas of the individual floors predetermined for this purpose and are interchangeable so that panels of different thicknesses can be produced with the multi-daylight press.

Das Auswechseln der Distanzelemente ist mühsam und zeitraubend, weil die Distanzelemente jeder Etage herausgenommen und durch neue ersetzt werden müssen. Dabei müssen die gegebenenfalls massiven und deshalb schweren Distanzelemente insbesondere der oberen Etagen bis in beträchtliche Höhen angehoben und in dieser Höhe ausgewechselt werden.Replacing the spacer elements is tedious and time-consuming because the spacer elements on each floor have to be removed and replaced with new ones. The possibly massive and therefore heavy spacer elements, in particular on the upper floors, must be raised to considerable heights and replaced at this height.

Bekannt ist eine Vorrichtung der eingangs beschriebenen Gattung (DE-OS 16 53 304), mit der Distanzleisten von einer Seite der Presse in diese eingeschoben werden, wodurch die in der Presse befindlichen Distanzleisten auf der anderen Seite der Presse wieder herausgeschoben und entnommen werden können. Damit können zwar die Distanzelemente aller Etagen gleichzeitig ausgewechselt werden, jedoch nur auf Kosten eines verhältnismäßig großen konstruktiven Aufwandes auf beiden Seiten der Presse.A device of the type described at the beginning (DE-OS 16 53 304) is known, with which spacer strips are inserted into the press from one side thereof, whereby the spacer strips located in the press can be pushed out and removed on the other side of the press. This means that the spacer elements on all floors can be replaced at the same time, but only at the expense of a relatively large amount of construction work on both sides of the press.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs beschriebenen Gattung konstruktiv und funktionell zu vereinfachen.The object of the invention is to simplify the construction and function of a device of the type described in the introduction.

Diese Aufgabe wird dadurch gelöst, daß die betreffende Tragsäule in horizontaler Richtung beweglich und um ihre Achse drehbar ist, daß jeder Etage zwei Tragfinger zugeordnet sind, deren gegenseitiger Abstand kleiner ist als die zugeordnete Abmessung der Distanzelemente und die sich beidseits über die Tragsäule hinauserstrecken, daß die betreffende Tragsäule auch in vertikaler Richtung verschiebbar ist, daß ferner die Tragfinger zueinander parallel verlaufen und die einzelnen Distanzelemente in einer Lage quer zu den Tragfingern abstützen, und daß schließlich beim Verfahren der Tragsäule zur Presse hin die Tragfinger von der betreffenden Etage vorstehende Pratzen zwischen sich aufnehmen, derart, daß beim Absenken der Tragsäule und damit der Tragfinger die Distanzelemente auf die Pratzen abgelegt werden.This object is achieved in that the support column in question is movable in the horizontal direction and rotatable about its axis, that two support fingers are assigned to each floor, the mutual spacing of which is smaller than the assigned dimension of the spacer elements and which extend beyond the support column on both sides in that the support column in question can also be displaced in the vertical direction, that the support fingers also run parallel to one another and support the individual spacer elements in a position transverse to the support fingers, and that when the support column moves towards the press, the support fingers protruding from the respective floor between them record, such that when lowering the support column and thus the support finger, the spacer elements are placed on the claws.

Beim Arbeiten mit der erfindungsgemäßen Vorrichtung werden die neuen Distanzelemente auf die Tragfinger auf der einen Seite der Tragsäule aufgelegt und wird dann die Tragsäule bis in den Bereich der Mehretagenpresse bewegt. Die Tragsäule wird so an die Mehretagenpresse herangefahren, daß die leeren Tragfinger auf der anderen Tragsäulenseite alle übereinander befindlichen Distanzelemente der verschiedenen Etagen gleichzeitig unterfassen und aufnehmen. Gegebenenfalls wird die Tragsäule dann ein Stück von der Mehretagenpresse weggefahren und um 180° gedreht, so daß die Tragfinger mit den daraufliegenden neuen Distanzelementen der Mehretagenpresse zugewandt sind. Dann wird die Tragsäule wieder an die Mehretagenpresse herangefahren, bis die Distanzelemente auf ihren zugeordneten Auflagern liegen. Nunmehr kann die Tragsäule wieder aus dem Bereich der Mehretagenpresse wegbewegt werden, und die Mehretagenpresse ist betriebsbereit. Dadurch ist es möglich, das Auswechseln und wegführen der Distanzelemente auf ein und derselben Seite der Presse durchzuführen.When working with the device according to the invention, the new spacer elements are placed on the supporting fingers on one side of the support column and the support column is then moved into the area of the multi-daylight press. The support column is moved to the multi-daylight press in such a way that the empty support fingers on the other side of the support column simultaneously grasp and accommodate all the spacer elements on the different floors, one above the other. If necessary, the support column is then moved away a little from the multi-daylight press and rotated through 180 °, so that the supporting fingers with the new spacer elements lying thereon face the multi-daylight press. Then the support column is moved back to the multi-daylight press until the spacer elements lie on their assigned supports. The support column can now be moved away from the area of the multi-daylight press and the multi-daylight press is ready for operation. This makes it possible to carry out the replacement and removal of the spacer elements on one and the same side of the press.

Zweckmäßig wird die Tragsäule mit im Bereich ihres oberen bzw. unteren Endes angeordneten Wagen in horizontaler Richtung bewegt. Die Wagen können auf Schienen laufen und mit Hubzylindern angetrieben sein. Das stellt sicher, daß die Tragsäule keine unerwünschten Eigenbewegungen ausführen kann, denn sie ist an ihren beiden Enden in den zugeordneten Wagen geführt, die gleichzeitig gleichsinnig bewegt werden.The support column is expediently moved in the horizontal direction with carriages arranged in the region of its upper or lower end. The carriages can run on rails and can be driven with lifting cylinders. This ensures that the support column can not perform any unwanted self-movements, because it is guided at both ends in the assigned car, which are simultaneously moved in the same direction.

Um das Aufnehmen bzw. Ablegen der Distanzelemente zu erleichtern, kann der obere Wagen eine angetriebene Seilwinde aufweisen, an deren Seil die Tragsäule aufgehängt ist, wobei der untere Wagen eine vertikale Führung für die Tragsäule aufweist. Damit ist die Tragsäule auch in vertikaler Richtung, also in Richtung ihrer Längsachse beweglich und kann zur Aufnahme bzw. zum Ablegen der Distanzelemente um ein kurzes Stück angehoben bzw. abgesenkt werden. Darüber hinaus besteht aber auch die Möglichkeit, die Tragsäule insgesamt so weit abzusenken, daß die Tragfinger zum Auflegen anderweitig gelagerter Distanzelemente oder zum Abnehmen von aus der Presse entnommenen Distanzelemente in eine normale Arbeitshöhe gebracht werden können.In order to make it easier to pick up or put down the spacer elements, the upper carriage can have a driven cable winch, on the rope of which the support column is suspended, the lower carriage having a vertical guide for the support column. The support column can thus also be moved in the vertical direction, that is to say in the direction of its longitudinal axis, and can be raised or lowered by a short distance in order to receive or deposit the spacer elements. In addition, there is also the possibility of lowering the support column as a whole so that the supporting fingers can be brought to a normal working height for placing spacer elements mounted elsewhere or for removing spacer elements removed from the press.

Die vertikale Führung der unteren Wagen kann aus U-förmigen Profilen bestehen, in die leistenförmige vertikale Führungsfahnen der Tragsäule eingreifen. Zweckmäßig werden die Führungsfahnen der Tragsäule so angeordnet, daß sie sich orthogonal zu den Tragfingern erstrecken und diese überragen.The vertical guidance of the lower carriages can consist of U-shaped profiles, in which the strip-shaped vertical guide lugs of the support column engage. The guide lugs of the support column are expediently arranged such that they extend orthogonally to the support fingers and protrude above them.

Damit die mit der Seilwinde abgelassene Tragsäule nach dem Anheben bis in den Bereich des oberen Wagens relativ zu diesem wieder eine definierte Position einnimmt, ist es zweckmäßig, wenn der obere Wagen eine Zentrierhülse für einen am oberen Ende der Tragsäule angeordneten Zentrierzapfen aufweist. Insbesondere kann der Zentrierzapfen ein teilweise verjüngter Endabschnitt der Tragsäule sein.So that the support column lowered with the winch after lifting up to the area of the upper carriage relative to this again assumes a defined position, it is expedient if the upper carriage has a centering sleeve for a centering pin arranged at the upper end of the support column. In particular, the centering pin can be a partially tapered end section of the support column.

Am oberen Wagen kann auch ein Drehantrieb für die Tragsäule angeordnet sein, die ein mit einem Ritzel des Drehantriebes in Eingriff bringbares Zahnrad aufweist. Um nichtsdestoweniger die Führung der Tragsäule am unteren Wagen zu erhalten, wird dazu am unteren Ende der Tragsäule eine gegenüber dieser drehbare Büchse mit gesonderten Führungsfahnen angeordnet, so daß die am oberen Wagen mit der Seilwinde gehaltene und am unteren Wagen geführte Tragsäule mit dem Drehantrieb um ihre Längsachse verdreht werden kann.A rotary drive for the support column can also be arranged on the upper carriage and has a gearwheel which can be brought into engagement with a pinion of the rotary drive. In order to nonetheless maintain the guidance of the support column on the lower carriage, a bushing which can be rotated with respect to this with separate guide tabs is arranged at the lower end of the support column, so that the support column held on the upper carriage with the cable winch and guided on the lower carriage with the rotary drive around it Longitudinal axis can be rotated.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß die Tragfinger, ausgehend von einer Mittellängsebene der Tragsäule, sich schräg nach unten erstrecken oder an den vorderen Enden abgeschrägt sind. Dann kann nämlich das Aufbringen der Distanzelemente auch durch horizontale und anschließend vertikale Bewegung erfolgen, wobei auf der Ablagefläche liegende Schmutzteile abgeschoben werden. Da die Distanzelemente wenigstens teilweise unter Materialberührung über die Auflager geschoben werden, empfiehlt es sich, die Auflager mit einer Verschleißplatte zu versehen.A preferred embodiment of the invention is characterized in that the support fingers, starting from a central longitudinal plane of the support column, extend obliquely downwards or are chamfered at the front ends. Then the spacer elements can then also be applied by horizontal and then vertical movement, with dirt particles lying on the storage surface being pushed off. Since the spacer elements are at least partially pushed over the supports while touching the material, it is advisable to provide the supports with a wear plate.

Im übrigen können die Tragfinger Anschläge zur Begrenzung einer relativen Horizontalbewegung zwischen Tragfingern und Distanzelementen aufweisen.In addition, the support fingers can have stops to limit a relative horizontal movement between support fingers and spacer elements.

Schließlich kann unterhalb des unteren Wagens eine Grube mit vertikalen Führungen angeordnet sein, wobei diese Führungen den Führungen am unteren Wagen entsprechen und so angeordnet sind, daß die Tragsäule in einer von der Etagenpresse entfernten Position in die Grube absenkbar ist. Durch schrittweises Absenken können dann die den einzelnen Etagen zugeordneten Tragfinger in eine normale Arbeitshöhe gebracht werden, damit Distanzelemente von diesen Tragfingern abgenommen oder auf sie aufgelegt werden.Finally, a pit with vertical guides can be arranged below the lower carriage, which guides correspond to the guides on the lower carriage and are arranged such that the support column can be lowered into the pit in a position remote from the deck press. By gradually lowering the support fingers assigned to the individual floors can be brought to a normal working height so that spacer elements can be removed from these support fingers or placed on them.

In Fig. 1 ist eine Mehretagenpresse 1 üblicher Bauart dargestellt, die mehrere, gegebenenfalls als Heizplatten ausgebildete Etagen 2 aufweist. Die Etagen 2 besitzen stirnseitig vorstehende Pratzen 3 als Auflager für plattenförmige Distanzelemente 4. Die Distanzelemente 4 besitzen Zentrierstifte 5, die in zugeordnete Zentrierbohrungen 42 der Pratzen 3 eingreifen (Fig. 4 und 5).In Fig. 1, a multi-daylight press 1 of conventional design is shown, which has a plurality of levels 2, optionally designed as heating plates. The levels 2 have protruding claws 3 on the end face as supports for plate-shaped spacer elements 4. The spacer elements 4 have centering pins 5 which engage in the associated centering holes 42 in the claws 3 (FIGS. 4 and 5).

Neben der Mehretagenpresse 1 befindet sich eine Vorrichtung zum Wechseln der Distanzelemente 4.In addition to the multi-daylight press 1 there is a device for changing the spacer elements 4.

Diese Vorrichtung besteht zunächst aus einem oberhalb der obersten Etage 2 angeordneten Traggerüst 6 für horizontale Schienen 7, auf denen mit Rollen 8 ein Wagen 9 verfahrbar ist. Wie man insbesondere aus Fig. 2 entnimmt, besteht der Wagen 9 im wesentlichen nur aus einem rahmenartigen Gerüst, an das eine Kolbenstange 10 eines Hubzylinders 11 angeschlossen ist, der seinerseits am Traggerüst 6 abgestützt ist. Durch Betätigen des Hubzylinders 11 kann der Wagen 9 in horizontaler Richtung auf die Mehretagenpresse 1 zu und von dieser wegbewegt werden.This device initially consists of a support structure 6 for horizontal rails 7 arranged above the top floor 2, on which rollers 8 a carriage 9 can be moved. As can be seen in particular from FIG. 2, the carriage 9 essentially consists only of a frame-like frame, to which a piston rod 10 of a lifting cylinder 11 is connected, which in turn is supported on the supporting frame 6. By actuating the lifting cylinder 11, the carriage 9 can be moved towards and away from the multi-daylight press 1 in the horizontal direction.

Auf dem Wagen 9 ist ein Motor 12 mit einem Getriebe 13 als Antrieb für eine Seilwinde 14 angeordnet. Das Ende des auf die Seilwinde 14 aufgewickelten Seils ist am Wagen 9 oder an einem damit verbundenen Teil so befestigt, daß eine Seilschlaufe gebildet ist, in der eine Umlenkrolle 15 geführt ist, die in einem gabelförmigen Lager 16 gehalten ist. Das Lager 16 ist am Ende einer vertikalen Tragsäule 17 um die Längsachse 18 dieser Tragsäule 17 drehbar angeordnet. Die Tragsäule 17 weist an ihrem oberen, das Lager 16 tragende Ende einen konischen Abschnitt 19 auf, der als Zentrierabschnitt zum Einführen der Tragsäule in eine am Wagen 9 befestigte Zentrierbuchse 20 dient (Fig. 1 c).A motor 12 with a gear 13 as a drive for a cable winch 14 is arranged on the carriage 9. The end of the cable wound on the cable winch 14 is attached to the carriage 9 or to a part connected thereto in such a way that a cable loop is formed in which a deflection roller 15 is guided, which is held in a fork-shaped bearing 16. The bearing 16 is arranged rotatably at the end of a vertical support column 17 about the longitudinal axis 18 of this support column 17. The support column 17 has at its upper end, which supports the bearing 16, a conical section 19 which serves as a centering section for inserting the support column into a centering bush 20 fastened to the carriage 9 (FIG. 1 c).

Außerdem ist auf dem Wagen 9 ein weiterer Motor 21 mit vertikaler Drehachse angeordnet, dem ein Getriebe 22 zugeordnet ist, das ein Ritzel 23 aufweist, welches in der in Fig. 1 c dargestellten Position mit einem auf der Tragsäule 17 befestigten Zahnrad 24 kämmt. Bei Betätigung des Motors 21 wird die Tragsäule 17 um ihre Längsachse 18 verdreht.In addition, a further motor 21 with a vertical axis of rotation is arranged on the carriage 9, to which a gear 22 is assigned which has a pinion 23 which meshes with a gearwheel 24 fastened to the support column 17 in the position shown in FIG. 1c. When the motor 21 is actuated, the support column 17 is rotated about its longitudinal axis 18.

Die Tragsäule 17 weist über ihre Länge verteilt eine der Anzahl der Etagen 2 entsprechende Zahl von Tragfingern 25, 26 auf. Die Tragfinger 25, 26 jeder Ebene erstrecken sich parallel zueinander und weisen einen Abstand auf, der etwas geringer ist als die entsprechende Abmessung der Distanzelemente 4.The support column 17 has, over its length, a number of support fingers 25, 26 corresponding to the number of levels 2. The support fingers 25, 26 of each level extend parallel to one another and are at a distance which is slightly less than the corresponding dimension of the spacer elements 4.

Am unteren Ende der Tragsäule 17 sind wiederum horizontale Schienen 43 für einen darauf mit Rollen 27 verfahrbaren Wagen 28 angeordnet, der mit einem Hubzylinder 29 zusammen und gleichsinnig mit dem Wagen 9 in horizontaler Richtung verfahrbar ist.At the lower end of the support column 17, horizontal rails 43 are in turn arranged for a carriage 28 movable thereon with rollers 27, which together with a lifting cylinder 29 and in the same direction as the carriage 9 in horizontal direction is movable.

Das untere Ende der Tragsäule 17 geht in einen Zapfen 30 über, auf dem mit Wälzlagern 31 eine Büchse 32 drehbar gelagert ist, die zwei Führungsfahnen 33 trägt, welche sich, einander diametral gegenüberliegend, radial und vertikal erstrecken (Fig. 1 c). Die Führungsfahnen 33 greifen in zugeordnete U-förmige Führungsprofile 34 an den Innenseiten des Wagen 28 ein. Dadurch ist die Tragsäule am unteren Wagen 28 zwar gegen eine Relativbewegung in horizontaler Richtung gesichert, in vertikaler Richtung jedoch frei verschieblich und außerdem gegenüber dem unteren Wagen 28 um ihre Längsachse 18 verdrehbar (Fig. 1 c).The lower end of the support column 17 merges into a pin 30 on which a bushing 32 is rotatably mounted with roller bearings 31 and carries two guide tabs 33 which extend diametrically opposite one another radially and vertically (FIG. 1 c). The guide lugs 33 engage in associated U-shaped guide profiles 34 on the inside of the carriage 28. As a result, the support column on the lower carriage 28 is secured against relative movement in the horizontal direction, but is freely displaceable in the vertical direction and can also be rotated about its longitudinal axis 18 with respect to the lower carriage 28 (FIG. 1 c).

Wie man insbesondere aus Fig. 1 entnimmt, besitzt die Tragsäule 17 über ihre gesamte Länge gegebenenfalls unterbrochene Führungsfahnen 35, deren Anordnung und Funktion den Führungsfahnen 33 an der Buchse 32 entspricht. Infolgedessen kann die Tragsäule 17 durch Nachlassen der Seilwinde 14 bei vertikaler Führung abgesenkt werden. Das ist in Fig. 1 c mit strichpunktierten Linien angedeutet. Unterhalb des unteren Wagens 28 befindet sich eine Grube 36, die hinreichend tief ist, so daß die Tragsäule 17 bis etwa in die dargestellte Position abgesenkt werden kann. Dabei hängt die Tragsäule 17 am Seil 37. An den Seitenwänden der Grube 36 befinden sich vertikale U-förmige Führungsprofile 38, in die die Führungsfahnen 33 bzw. 35 der Tragsäule 17 eingreifen, wenn der obere Wagen 9 und der untere wagen 28 durch Betätigen der Hubzylinder 11 bzw. 29 in die äußere dargestellte Position verfahren sind, bei der die U-förmigen Führungen 34 des unteren Wagens 28 mit den U-förmigen Führungen 38 der Grube 36 fluchten (Fig. 1 b, 1 c).As can be seen in particular from FIG. 1, the support column 17 has possibly interrupted guide lugs 35 along their entire length, the arrangement and function of which corresponds to the guide lugs 33 on the bush 32. As a result, the support column 17 can be lowered by releasing the cable winch 14 with vertical guidance. This is indicated in Fig. 1 c with dash-dotted lines. Below the lower carriage 28 there is a pit 36 which is sufficiently deep that the support column 17 can be lowered to approximately the position shown. The support column 17 hangs on the rope 37. On the side walls of the pit 36 there are vertical U-shaped guide profiles 38, into which the guide lugs 33 and 35 of the support column 17 engage when the upper carriage 9 and the lower carriage 28 by actuating the Lift cylinders 11 and 29 are moved into the outer position shown, in which the U-shaped guides 34 of the lower carriage 28 are aligned with the U-shaped guides 38 of the pit 36 (Fig. 1 b, 1 c).

Die dargestellte Vorrichtung arbeitet wie folgt: In der in Fig. 1b dargestellten abgesenkten Position werden auf die Tragfinger 25, 26 der Tragsäule 17 Distanzelemente 4 aufgelegt, wobei gegebenenfalls die Tragsäule durch Betätigen des Antriebs 12 schrittweise angehoben wird. Um ein Verrutschen der Distanzelemente auf den Tragfingern 25, 26 zu verhindern, weisen die Tragfinger 25, 26 vorstehende Stifte 39 auf, die in zugeordnete Öffnungen der Distanzplatten eingreifen. Wenn sämtliche auf einer Seite der Tragsäule 17 befindliche Tragfinger 25, 26 mit Distanzelementen 4 beladen sind, wird die Tragsäule mit ihrem oberen konischen Abschnitt 19 in die Zentrierbuchse 20 am oberen Wagen 9 eingezogen, wobei gleichzeitig die Führungsfahnen 33 der drehbaren Buchse 32 am unteren Ende der Tragsäule in das U-förmige Führungsprofil 34 des Wagens 28 eingreifen (Fig. 1 c).The device shown works as follows: In the lowered position shown in FIG. 1b, spacer elements 4 are placed on the supporting fingers 25, 26 of the support column 17, the support column being optionally raised step by step by actuating the drive 12. In order to prevent the spacer elements from slipping on the supporting fingers 25, 26, the supporting fingers 25, 26 have protruding pins 39 which engage in assigned openings in the spacer plates. When all of the support fingers 25, 26 on one side of the support column 17 are loaded with spacer elements 4, the support column is drawn with its upper conical section 19 into the centering bushing 20 on the upper carriage 9, with the guide tabs 33 of the rotatable bushing 32 at the lower end at the same time engage the support column in the U-shaped guide profile 34 of the carriage 28 (Fig. 1 c).

In der Mehretagenpresse 1 befinden sich Distanzelemente 4, die ausgewechselt werden sollen. Dazu wird die Tragsäule 17 durch Betätigen der Hubzylinder 11 bzw. 29 so weit in Richtung auf die Pratzen 3 der Mehretagenpresse 1 verfahren, bis die freien Enden der Tragfinger 25, 26 die zugeordneten, auf den Pratzen 3 aufliegenden Distanzelemente 4 unterfassen. Die Tragsäule 17 wird dann durch Betätigen des Motors 12 ein kurzes Stück angehoben und durch Betätigen der Hubzylinder 11 bzw. 29 aus dem Bereich der Presse gefahren. Nunmehr kann die Tragsäule 17 durch Betätigen des Motors 21 um 180° gedreht werden, so daß die nicht mehr benötigten Distanzelemente aus dem Bereich der Mehretagenpresse herausgeschwenkt und die neuen Distanzelemente zu den zugeordneten Auflagern der Pratzen 3 geschwenkt werden. Nach erneutem Verfahren in Richtung auf die Pratzen 3 wird die Tragsäule 17 wieder abgesenkt, so daß die neuen Distanzelemente 4 auf ihren Auflagern abgesetzt oder auf diese geschoben werden, wobei ihre Zentrierstifte 5 in die zugeordneten Zentrieröffnungen der Auflager einfassen. Die Tragsäule 17 wird dann durch Betätigen der Hubzylinder 11 bzw. 26 aus dem Bereich der Mehretagenpresse 1 weggefahren. Die Mehretagenpresse ist damit wieder betriebsbereit.Spacer elements 4 which are to be replaced are located in the multi-daylight press 1. For this purpose, the support column 17 is moved by actuating the lifting cylinders 11 and 29 in the direction of the claws 3 of the multi-daylight press 1 until the free ends of the support fingers 25, 26 underlie the associated spacer elements 4 resting on the claws 3. The support column 17 is then raised a short distance by actuating the motor 12 and moved out of the press area by actuating the lifting cylinders 11 and 29. The support column 17 can now be rotated by 180 ° by actuating the motor 21, so that the spacer elements no longer required are pivoted out of the area of the multi-daylight press and the new spacer elements are pivoted to the associated supports of the claws 3. After another procedure in the direction of the claws 3, the support column 17 is lowered again, so that the new spacer elements 4 are placed on their supports or pushed onto them, their centering pins 5 engaging in the associated centering openings of the supports. The support column 17 is then moved away from the area of the multi-daylight press 1 by actuating the lifting cylinders 11 and 26. The multi-daylight press is now ready for use again.

Bei dem in den Fig. 4a, 4b und 5 dargestellten Ausführungsbeispiel sind die Tragfinger 25 bzw. 26 gegenüber der Horizontalen abgeschrägt ausgeführt. Dementsprechend werden auch die Distanzelemente 4 in geneigter Lage transportiert und auf die Pratzen 3, die mit einer Verschleißauflage 40 versehen sind, aufgeschoben. Das geschieht beim dargestellten Ausführungsbeispiel ausschließlich durch horizontale Bewegung der Tragsäule 17 mit den daran angeschlossenen abgeschrägten Tragfindern 25 bzw. 26. Man erkennt, daß bei der in Fig. 4 dargestellten Anordnung während des Einfahrens der Tragfinger 25, 26 in den Bereich der Pratzen 3 das Distanzelement 4 zunächst einseitig auf der Verschleißauflage 40 aufliegt und von den Tragfingern 25, 26 gegebenenfalls mit einem Anschlag 41 in Richtung auf die Etage verschoben wird, wobei die Distanzplatte mit einer Kante über die Verschleißplatte 40 gleitet. Wenn das Distanzelement 4 ungefähr seine richtige Position erreicht hat, wird die Tragsäule 17 mit den Tragfingern 25, 26 abgesenkt und das Distanzelement 4 auf einer als Auflager dienenden Verschleißplatte 40 abgelegt, wobei die Zentrierstifte 5 in zugeordnete Zentrieröffnungen 42 einfassen und das Distanzelement 4 ausrichten.In the embodiment shown in FIGS. 4a, 4b and 5, the supporting fingers 25 and 26 are slanted relative to the horizontal. Correspondingly, the spacer elements 4 are also transported in an inclined position and pushed onto the claws 3, which are provided with a wear pad 40. This is done in the illustrated embodiment exclusively by horizontal movement of the support column 17 with the beveled support finders 25 and 26 connected to it. It can be seen that in the arrangement shown in FIG Spacer 4 initially rests on one side on the wear support 40 and is displaced by the support fingers 25, 26, if necessary with a stop 41, in the direction of the floor, the spacer plate sliding over the wear plate 40 with one edge. When the spacer 4 has approximately reached its correct position, the support column 17 is lowered with the support fingers 25, 26 and the spacer 4 is placed on a wear plate 40 serving as a support, the centering pins 5 engaging in assigned centering openings 42 and aligning the spacer 4.
