  • the function of the device e.g. in the area of an unloading station for the fired ceramic parts, the following is:
  • the documents loaded with ceramic parts are placed in rows arranged transversely to the longitudinal direction of the orbit on the first conveyor by means of the stacking and unstacking device and conveyed to the emptying device, where the cassettes are emptied.
  • the empty cassettes are conveyed again by the second conveyor under the stacking and unstacking device, which they stack again on the or a kiln car.
  • the ends of the conveyors facing the filling or emptying device are connected to one another by a third conveyor which conveys the cassettes from the first conveyor to a middle position between the latter and the second conveyor, in which the cassettes are emptied and then to the second conveyor.
  • the known design is very complex. This is due to the fact that the conveyor has two conveyors, which leads to high manufacturing costs. In addition, there is a significant space requirement not only for the first and second conveyor, but also for the third conveyor.
  • the first and the second conveyor are supported on a table which extends above the kiln car and is referred to as a work table. This designation is misleading because the table does not participate in the stacking or unstacking or in the conveyance of the cassettes to the filling or emptying device and back.
  • the table thus only serves to support the first and second and apparently also the third conveyor.
  • the invention has for its object to design a device of the type mentioned in such a way that, while ensuring simultaneous stacking or unstacking and filling or emptying of the documents, the conveyor can be manufactured more simply and in a smaller design.

  • FR-PS 2120 335 It is already known from FR-PS 2120 335 to use a conveyor device with only one conveyor in a device for loading or unloading kiln cars passing through a kiln for ceramic parts in an orbit, but in this known embodiment the filling or emptying device is not arranged to the side of the orbit, but integrated into the stacking and unstacking device. Simultaneous stacking or unstacking and filling or emptying is therefore not possible.
  • the conveyor serving for the removal or supply of only the ceramic parts is set up only for the conveyance into a conveying device.

Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Eine Vorrichtung dieser Art ist in der DE-AS 27 05 074 beschrieben und dargestellt.A device of this type is described and shown in DE-AS 27 05 074.

Bei der bekannten Ausgestaltung besteht die Fördereinrichtung aus zwei, in Fahrtrichtung der Ofenwagen hintereinanderliegenden und einen Abstand zwischen sich aufweisenden Förderern, von denen der in Fahrtrichtung erste für die Förderung der Unterlagen von der Stapel- oder Entstapelvorrichtung zur Befüll- oder Entleerungsvorrichtung und der zweite für die Förderung von der Befüll-oder Entleerungsvorrichtung zur Stapel- oder Entstapelvorrichtung eingerichtet ist. Die Funktion der Vorrichtung, z.B. im Bereich einer Entladestation für die gebrannten Keramikteile, ist folgende:In the known embodiment, the conveyor consists of two, one behind the other in the direction of travel of the kiln cars and having a distance between them, the first in the direction of travel for conveying the documents from the stacking or unstacking device to the filling or emptying device and the second for Conveying is set up from the filling or emptying device to the stacking or unstacking device. The function of the device, e.g. in the area of an unloading station for the fired ceramic parts, the following is:

Die mit Keramikteilen beladenen Unterlagen, in diesem Falle Kassetten, werden in quer zur Längsrichtung der Umlaufbahn angeordneten Reihen mittels der Stapel- und Entstapelvorrichtung auf den ersten Förderer gesetzt und zur Entleerungsvorrichtung gefördert, wo die Kassetten entleert werden. Die leeren Kassetten werden durch den zweiten Förderer wieder unter die Stapel- und Entstapelvorrichtung gefördert, die sie wieder auf den oder einen Ofenwagen stapelt.The documents loaded with ceramic parts, in this case cassettes, are placed in rows arranged transversely to the longitudinal direction of the orbit on the first conveyor by means of the stacking and unstacking device and conveyed to the emptying device, where the cassettes are emptied. The empty cassettes are conveyed again by the second conveyor under the stacking and unstacking device, which they stack again on the or a kiln car.

Die der Befüll- oder Entleerungsvorrichtung zugewandten Enden der Förderer sind durch einen dritten Förderer miteinander verbunden, der die Kassetten vom ersten Förderer zu einer Mittelstellung zwischen letzterem und dem zweiten Förderer, in der die Kassetten entleert werden und dann zum zweiten Förderer fördert.The ends of the conveyors facing the filling or emptying device are connected to one another by a third conveyor which conveys the cassettes from the first conveyor to a middle position between the latter and the second conveyor, in which the cassettes are emptied and then to the second conveyor.

Die bekannte Ausgestaltung ist sehr aufwendig. Dies ist dadurch bedingt, daß die Fördereinrichtung zwei Förderer aufweist, was zu hohen Herstellungskosten führt. Außerdem ergibt sich nicht nur für den ersten und zweiten Förderer, sondern zusätzlich auch durch den dritten Förderer ein bedeutender Raumbedarf.The known design is very complex. This is due to the fact that the conveyor has two conveyors, which leads to high manufacturing costs. In addition, there is a significant space requirement not only for the first and second conveyor, but also for the third conveyor.

Bei der bekannten Ausgestaltung sind der erste und der zweite Förderer auf einem Tisch abgestützt, der sich oberhalb der Ofenwagen erstreckt und mit Arbeitstisch bezeichnet ist. Diese Bezeichnung ist insofern irreführend, weil der Tisch weder an der Stapelung bzw. Entstapelung noch an der Förderung der Kassetten zur Befüll- oder Entleerungsvorrichtung und zurück teilnimmt. Der Tisch dient somit lediglich der Abstützung des ersten und des zweiten sowie offenbar auch des dritten Förderers.In the known embodiment, the first and the second conveyor are supported on a table which extends above the kiln car and is referred to as a work table. This designation is misleading because the table does not participate in the stacking or unstacking or in the conveyance of the cassettes to the filling or emptying device and back. The table thus only serves to support the first and second and apparently also the third conveyor.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs bezeichneten Art so auszugestalten, daß bei Gewährleistung eines gleichzeitigen Stapelns bzw. Entstapelns und Befüllens bzw. Entleerens der Unterlagen die Fördereinrichtung einfacher und in kleinerer Bauweise hergestellt werden kann.The invention has for its object to design a device of the type mentioned in such a way that, while ensuring simultaneous stacking or unstacking and filling or emptying of the documents, the conveyor can be manufactured more simply and in a smaller design.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 enthaltenen Merkmale gelöst.This object is achieved by the features contained in the characterizing part of claim 1.

Bei der erfindungsgemäßen Vorrichtung umfaßt die Fördereinrichtung nur einen Förderer, wodurch die angestrebte Vereinfachung und kleine Bauweise erreicht wird. Mit diesem Förderer werden die Unterlagen sowohl von der Stapel- und Entstapelvorrichtung zur Befüll- oder Entleerungsvorrichtung als auch umgekehrt gefördert. Dies ist durch einen bezüglich seiner Förderichtung umkehrbaren oder reversiblen Förderer erreichbar. Da kein zweiter Förderer gemäß der bekannten Ausgestaltung vorhanden ist, bedarf es auch keines dritten Förderers, wie es bei der bekannten Ausgestaltung ebenfalls der Fall ist.In the device according to the invention, the conveyor device comprises only one conveyor, whereby the desired simplification and small construction is achieved. With this conveyor, the documents are conveyed from the stacking and unstacking device to the filling or emptying device and vice versa. This can be achieved by means of a reversible or reversible conveyor with regard to its conveying direction. Since there is no second conveyor according to the known configuration, there is also no need for a third conveyor, as is also the case with the known configuration.

Ein gleichzeitiges Stapeln bzw. Entstapeln und Befüllen bzw. Entleeren der Unterlagen ist bei der erfindungsgemäßen Ausgestaltung durch den in Längsrichtung der Umlaufbahn verschiebbaren Träger mit wenigstens zwei Stellplätzen bzw. Stellplatzreihen für die Unterlagen gewährleistet. Während der Förderung der Unterlagen von der Stapel-und Entstapelvorrichtung zur Befüll- oder Entlleerungsvorrichtung und zurüci steht somit wenigstens ein weiterer Stellplatz bzw. eine weitere Stellplatzreihe zur Verfügung, auf die eine Unterlage bzw. eine Reihe Unterlagen abgesetzt oder entnommen werden kann; das heißt, die Stapel- und Entstapelvorrichtung und die Befüll- oder Entleerungsvorrichtung können gleichzeitig arbeiten.Simultaneous stacking or unstacking and filling or emptying of the documents is ensured in the embodiment according to the invention by the carrier which can be displaced in the longitudinal direction of the orbit and has at least two parking spaces or rows of parking spaces for the documents. During the conveyance of the documents from the stacking and unstacking device to the filling or emptying device and back, at least one further parking space or a further row of parking spaces is thus available, onto which a document or a series of documents can be placed or removed; that is, the stacking and unstacking device and the filling or emptying device can work simultaneously.

Es ist aus der FR-PS 2120 335 zwar bereits bekannt, bei einer Vorrichtung zum Be- oder Entladen von einen Brennofen für Keramikteile auf einer Umlaufbahn durchlaufenden Ofenwagen eine Fördereinrichtung mit nur einem Förderer einzusetzen, jedoch ist bei dieser bekannten Ausgestaltung die Befüll- oder Entleerungsvorrichtung nicht seitlich neben der Umlaufbahn angeordnet, sondern in die Stapel- und Entstapelvorrichtung integriert. Ein gleichzeitiges Stapeln bzw. Entstapeln und Befüllen bzw. Entleeren ist somit nicht möglich. Außerdem ist der der Abführung bzw. Zuführung lediglich der Keramikteile dienende Förderer nur für die Förderung in eine Fördereinrichtung eingerichtet. Ein Träger gemäß der erfindungsgemäßen Lösung ist bei dieser bekannten Ausgestaltung nicht vorgesehen.It is already known from FR-PS 2120 335 to use a conveyor device with only one conveyor in a device for loading or unloading kiln cars passing through a kiln for ceramic parts in an orbit, but in this known embodiment the filling or emptying device is not arranged to the side of the orbit, but integrated into the stacking and unstacking device. Simultaneous stacking or unstacking and filling or emptying is therefore not possible. In addition, the conveyor serving for the removal or supply of only the ceramic parts is set up only for the conveyance into a conveying device. A carrier according to the solution according to the invention is not provided in this known embodiment.

Im Rahmen der Erfindung ist es möglich, nach Anspruch 2 die Fördereinrichtung des Trägers durch jeweils im Bereich der Stellplätze angeordnete Einzelförderer oder durch einen einzigen Förderer zu bilden, dessen Breite sich über die Stellplätze erstreckt.Within the scope of the invention, it is possible, according to claim 2, to form the conveying device of the carrier by individual conveyors arranged in the area of the parking spaces or by a single conveyor, the width of which extends over the parking spaces.

Im Anspruch 3 sind einfache Aggregate enthalten, die einen kontinuierlichen Betrieb gewährleisten.In claim 3 simple units are included, which ensure continuous operation.

In den meisten Fällen wird angestrebt, die Beladestation möglichst in der Nähe des Ofeneingangs und die Entladestation möglichst in der Nähe des Ofenausgangs anzuordnen, um eine unnütze Förderung der Keramikteile auf Umlaufbahn und eine hierdurch bedingte Fertigungsverzögerung zu vermeiden. Dies ist durch eine Ausbildung gemäß Anspruch 4 möglich, bei der zwei Vorrichtungen vorhanden sind, von denen die eine zum Beladen und die andere zum Entladen eingerichtet ist.In most cases, the aim is to arrange the loading station as close as possible to the furnace entrance and the unloading station as close as possible to the furnace outlet in order to avoid unnecessary conveyance of the ceramic parts into orbit and a consequent production delay. This is possible by an embodiment according to claim 4, in which there are two devices, one of which is set up for loading and the other for unloading.

Die Ansprüche 5 bis 7 geben im Rahmen der Erfindung lediglich eine andere Anordnung der verschiebbaren Träger wieder.Within the scope of the invention, claims 5 to 7 only show another arrangement of the displaceable carriers.

Nachfolgend wird die Erfindung anhand von in Zeichnungen dargestellten bevorzugten Ausführungsbeispielen näher erläutert. Es zeigen:

  • Fig. 1 in vereinfachter Darstellung und in Draufsicht einen rückführenden Abschnitt einer Umlaufbahn für einen Brennofen mit zwei erfindungsgemäß ausgestalteten Vorrichtungen zum Beladen bzw. Entladen der Ofenwagen;
  • Fig. 2 einen der Linie 11-11 entsprechenden Schnitt durch eine Vorrichtung als zweites Ausführungsbeispiel;
  • Fig. 3 eine Variante der Vorrichtungen in Draufsicht mit in die Befüll- oder Entleerungsvorrichtung integriertem verschiebbaren Träger.
The invention is explained in more detail below on the basis of preferred exemplary embodiments illustrated in the drawings. Show it:
  • 1 shows a simplified representation and a top view of a returning section of an orbit for a kiln with two devices designed according to the invention for loading or unloading the kiln cars;
  • 2 shows a section corresponding to line 11-11 through a device as a second exemplary embodiment;
  • Fig. 3 shows a variant of the devices in plan view with a movable carrier integrated in the filling or emptying device.

Auf der allgemein mit 1 bezeichneten Umlaufbahn werden hintereinander angeordnete, nur in Fig. 2 im einzelnen angedeutete Ofenwagen 2 in Fahrtrichtung (Pfeil 3) vorbewegt. Auf den Ofenwagen 2 sind in quer zur Fahrtrichtung 3 angeordneten Reihen 4 in Kassetten aufgenommene Keramikteile, wie beispielsweise Dachpfannen, gestapelt. Die Kassetten und die Keramikteile sind im einzelnen nicht dargestellt. Die Darstellung der Kassetten als Reihen 4 reicht deshalb aus, weil die Kassetten reihenweise (Reihen 4) gehandhabt werden.On the orbit generally designated 1, kiln cars 2 arranged one behind the other and only indicated in detail in FIG. 2 are advanced in the direction of travel (arrow 3). Ceramic parts, such as roof tiles, are stacked on the kiln car 2 in rows 4 arranged transversely to the direction of travel 3. The cassettes and the ceramic parts are not shown in detail. The representation of the cartridges as rows 4 is sufficient because the cartridges are handled in rows (rows 4).

Die Vorrichtungen 5 und 6 sind einander gleich ausgebildet; sie werden jedoch nach unterschiedlichen Arbeitsverfahren betrieben, wobei die Vorrichtung 5 im Bereich einer Entladestation 7 angeordnet ist zum Entladen der Dachziegel und die Vorrichtung 6 im Bereich einer Beladestation 8 angeordnet ist und zum Beladen der Ofenwagen 2 mit Dachziegeln betrieben wird.The devices 5 and 6 are identical to one another; however, they are operated according to different working methods, the device 5 being arranged in the area of an unloading station 7 for unloading the roof tiles and the device 6 being arranged in the area of a loading station 8 and being operated for loading the kiln cars 2 with roof tiles.

Jede Vorrichtung 5,6 weist eine Stapel- und Entstapelvorrichtung in Form eines Greifers auf, der sich über die gesamte Breite (b) der Umlaufbahn 1 erstreckt und somit jeweils eine Reihe 4 der Kassetten gleichzeitig zu ergreifen vermag. Der Greifer ist der Höhe nach sowie in Längsrichtung der Umlaufbahn 1 verfahrbar und ist durch aufeinander zu und voneinander weg bewegliche Greifbacken 9 angedeutet.Each device 5, 6 has a stacking and unstacking device in the form of a gripper which extends over the entire width (b) of the orbit 1 and is thus able to grip a row 4 of the cassettes at the same time. The gripper can be moved in height and in the longitudinal direction of the orbit 1 and is indicated by gripping jaws 9 which can move towards and away from one another.

Jede Vorrichtung 5,6 umfaßt weiterhin einen quer zur Umlaufbahn 1 angeordneten Förderer 10, der oberhalb der Umlaufbahn 1 das heißt oberhalb der Ofenwagen 2, angeordnet ist und sich quer zur Umlaufbahn 1 bis zu einer Befüll- oder Entleerungsvorrichtung 11, 12 erstreckt. Der Befüll- und Entleerungsvorrichtung 11, 12 ist ein ebenfalls der Höhe nach und längs der Umlaufbahn 1 verfahrbarer Greifer zugeordnet, mit dem eine gestrichelt angedeutete Reihe 13 in noch zu beschreibender Weise gehandhabt werden kann.Each device 5, 6 further comprises a conveyor 10 arranged transversely to the orbit 1, which is arranged above the orbit 1, ie above the kiln car 2, and extends transversely to the orbit 1 up to a filling or emptying device 11, 12. The filling and emptying device 11, 12 is assigned a gripper which can also be moved vertically and along the orbit 1, with which a row 13 indicated by a broken line can be handled in a manner to be described.

An die Vorrichtung 12 schließt im Falle der Vorrichtung 5 ein Abführungsförderer 14 an, der, in Längsrichtung der Umlaufbahn 1 gesehen, vor, hinter oder seitlich neben dem freien Ende der Vorrichtung 12 angeordnet sein kann. Im Falle der Vorrichtung 6 ist kein Abführungsförderer, sondern ein Zuführungsförderer 15 vorgesehen, der sich vom Abführungsförderer 14 lediglich durch seine Förderrichtung unterscheidet, die entgegengerichtet ist.In the case of the device 5, the device 12 is followed by a discharge conveyor 14 which, viewed in the longitudinal direction of the orbit 1, can be arranged in front of, behind or to the side of the free end of the device 12. In the case of the device 6, there is no discharge conveyor, but rather a feed conveyor 15 which differs from the discharge conveyor 14 only in its conveying direction, which is opposite.

Jede Vorrichtung 5,6 weist auch einen Träger 16 mit zwei Stellplätzen 17, 18 für Kassetten auf, dessen Oberseite an die Förderfläche des Förderers 10 angepaßt ist, und der zwischen einer mit durchgezogenen Vollinien dargestellten Position und einer strichpunktiert angedeuteten Position hin und her, das heißt längs der Umlaufbahn 1, verschiebbar ist. Der Antrieb für den Träger 16 ist aus Vereinfachungsgründen nicht dargestellt. Es kann sich zum Beispiel um einen hydraulischen Kolben-Zylinder-Antrieb handeln. Die Führungen für den Träger 16 sind in Fig. 2 angedeutet und mit 19 bezeichnet, in denen der Träger 16 mit Rollen 21 geführt ist. In den Verschiebe-Endstellungen des Trägers 16 fluchtet entweder der Stellplatz 17 oder der Stellplatz 18 mit dem Förderer 10, das heißt die Länge des Verschiebeweges entspricht dem Mittelabstand zwischen den Stellplätzen 17, 18.Each device 5,6 also has a carrier 16 with two parking spaces 17, 18 for cassettes, the top of which is adapted to the conveying surface of the conveyor 10, and between a position shown by solid lines and a position indicated by dash-dotted lines back and forth, that means along the orbit 1, is displaceable. The drive for the carrier 16 is not shown for reasons of simplification. For example, it can be a hydraulic piston-cylinder drive. The guides for the carrier 16 are indicated in FIG. 2 and designated 19, in which the carrier 16 is guided with rollers 21. In the displacement end positions of the carrier 16, either the parking space 17 or the parking space 18 is aligned with the conveyor 10, that is to say the length of the displacement path corresponds to the center distance between the parking spaces 17, 18.

Im folgenden wird die Arbeitsweise zunächst der Vorrichtung 5 beschrieben, nämlich das Entladen der Dachziegel.In the following, the mode of operation of the device 5 is described, namely the unloading of the roof tiles.

Mit dem ersten Arbeitsschritt wird eine Reihe 4 mit Dachziegeln gefüllter Kassetten mittels der Greifbacken 9 von der mit A) bezeichneten Position auf den Ofenwagen 2 auf den Stellplatz 18, das heißt in die Position C), übergesetzt. Anschließend fördert der Förderer 10 diese Reihe Kassetten vom Stellplatz 18 zur Entleerungsvorrichtung 12, wo die mit 13 bezeichnete und punktiert angedeutete Reihe der Dachziegel mittels des durch Greifbacken 22 angedeuteten Greifers auf den Abführungsförderer 14 übergesetzt und abgeführt wird. Daraufhin wird die sich in der Entleerungsvorrichtung befindliche Reihe leerer Kassetten mittels des Förderers 10 zum Stellplatz 18 zurückgefördert. Während dieser Arbeitsschritte wird eine nächste Reihe 4 vom Ofenwagen 2 auf den Stellplatz 17 des Trägers 16 übergesetzt. Dann wird der Träger 16 in der Zeichnung nach rechts verschoben, so daß der Stellplatz 17 mit der darauf befindlichen Reihe gefüllter Kassetten in Flucht mit dem Förderer 10 gelangt, und der Stellplatz 18 die strichpunktiert angedeutete Position, das heißt die mit D) bezeichnete Position, einnimmt.In the first step, a row 4 of cassettes filled with roof tiles is transferred from the position designated A) to the kiln car 2 to the parking space 18, that is to the position C), by means of the gripping jaws 9. The conveyor 10 then conveys this row of cassettes from the parking space 18 to the emptying device 12, where the row of roof tiles, indicated and indicated by a dotted line, is transferred to the discharge conveyor 14 and discharged by means of the gripper indicated by gripping jaws 22. The row of empty cassettes located in the emptying device is then conveyed back to the parking space 18 by means of the conveyor 10. During these steps, a next row 4 is transferred from the kiln car 2 to the parking space 17 of the carrier 16. Then the carrier 16 is shifted to the right in the drawing, so that the parking space 17 with the row of filled cassettes located thereon is in alignment with the conveyor 10, and the parking space 18 the position indicated by dash-dotted lines, that is to say the position denoted by D), occupies.

Die nächsten Arbeitsschritte bestehen darin, die sich nunmehr in Flucht mit dem Förderer 10 befindliche Reihe gefüllter Kassetten zur Entleerungsvorrichtung 12 zu fördern, zu entleeren und wieder auf den Träger 16 zurückzufördern. Während dieser Arbeitsschritte wird die sich in der Position D) befindliche Reihe leerer Kassetten mittels der Greifbacken 9 zu einer mit E) bezeichneten Position auf den Ofenwagen 2 übergesetzt und ggf. gestapelt. Wenn der Träger 16 abschließend in die mit Vollinien dargestellte Position zurückfährt, ist der Stellplatz 18 - Position C) - frei und auf dem Stellplatz 17 - Position B) - befindet die sich zuletzt entleerte Reihe Kassetten.The next steps are to convey the row of filled cassettes, which are now in alignment with the conveyor 10, to the emptying device 12, to empty them and to convey them back to the carrier 16. During these work steps, the row of empty cassettes located in position D) is transferred by means of the gripping jaws 9 to a position labeled E) on the kiln car 2 and, if necessary, stacked. When the carrier 16 finally moves back into the position shown with solid lines, the parking space 18 - position C) - free and on the parking space 17 - position B) - the last emptied row of cassettes is located.

Der nächste Arbeitsschritt besteht darin, eine nächste Reihe gefüllter Kassetten von der Position A) auf den Stellplatz 18 - Position C - überzusetzen. Während der Entleerung dieser Reihe 4 Kassetten wird die leere Reihe Kassetten vom Stellplatz 17 - Position B) - zur Position E) auf den Ofenwagen 2 übergesetzt und eine weitere Reihe 4 gefüllter Kassetten von der Position A) auf den Stellplatz 17 - Position B) - übergesetzt, was jeweils durch die Greifbacken 9 erfolgt. Es ist auch möglich, diese Reihe 4 immer von A) nach C) zu übertragen, wobei im Falle des Stellplatzes 17 dieser jedoch erst in Flucht mit dem Förderer 10 geschoben werden muß.The next step is to move a next row of filled cassettes from position A) to position 18 - position C. During the emptying of this row of 4 cassettes, the empty row of cassettes is transferred from parking space 17 - position B) - to position E) onto the kiln car 2 and another row 4 of filled casings set from position A) to parking space 17 - position B) - transferred, which is done by the gripping jaws 9. It is also possible to always transfer this row 4 from A) to C), but in the case of the parking space 17, this must first be pushed in line with the conveyor 10.

Bei der erfindungsgemäßen Ausgestaltung kann das Entleeren der Reihen Kassetten auch das Übersetzen der Reihen gefüllter Kassetten auf den Träger 16 bzw. das Übersetzen der Reihen leerer Kassetten vom Träger 16 auf den Ofenwagen 2 - Position E) - gleichzeitig erfolgen. Während des Förderns und Entleerens einer Reihe Kassetten vom Stellplatz 18 wird der Stellplatz 18 - Position B) - entleert sowie neu besetzt und während des Förderns und Entleerens einer Reihe Kassetten vom Stellplatz 17 wird der Stellplatz 18 - Position D) - frei gemacht.In the embodiment according to the invention, the rows of cassettes can also be emptied, the rows of filled cassettes can be translated onto the carrier 16 or the rows of empty cassettes can be translated from the carrier 16 onto the kiln car 2 - position E) - simultaneously. During the conveying and emptying of a row of cassettes from the slot 18, the slot 18 - position B) - is emptied as well as occupied and during the conveying and emptying of a row of cassettes from the slot 17, the slot 18 - position D) - is cleared.

Die Arbeitsweise der Vorrichtung 6 zum Beladen der Ofenwagen 2 mit gefüllten Kassetten ist entsprechend; vergleiche Greifbacken 9, Positionen A) bis E) und Stellplätze 17 sowie 18. Es besteht lediglich der Unterschied, daß nicht Reihen 4 mit gefüllten Kassetten, sondern Reihen 4 mit leeren Kassetten von dem sich zwischen den Vorrichtungen 5, 6 befindlichen Speicherabschnitt auf den Träger 16 übertragen und Reihen 4 gefüllter Kassetten auf den Ofenwagen 2 - Position E) - übergesetzt werden. Das Befüllen der jeweiligen Reihe 4 Kassetten erfolgt durch Übersetzen der Dachziegel vom Zuführungsförderer 15 in die Reihe 4 Kassetten mittels der Greifbacken 22.The operation of the device 6 for loading the kiln car 2 with filled cassettes is corresponding; compare gripper jaws 9, positions A) to E) and parking spaces 17 and 18. There is only the difference that rows 4 with filled cassettes, rather than rows 4 with empty cassettes, are transferred from the storage section between the devices 5, 6 to the carrier 16 transferred and rows 4 filled cassettes on the kiln car 2 - position E) - are transferred. The respective row 4 cassettes are filled by translating the roof tiles from the feed conveyor 15 into the row 4 cassettes by means of the gripping jaws 22.

Die Arbeitsschritte zum Entladen oder Beladen können von Hand oder durch ein Programm automatisch gesteuert werden.The work steps for unloading or loading can be controlled automatically or by a program.

Im Rahmen der Erfindung ist es möglich, einen Träger 16 mit mehr als zwei Stellplätzen 17, 18 anzuordnen und somit den Träger im größeren Umfang als Speicher für Reihen 4 mit gefüllten oder entleerten Kassetten auszunutzen.In the context of the invention it is possible to arrange a carrier 16 with more than two parking spaces 17, 18 and thus to utilize the carrier to a larger extent as a memory for rows 4 with filled or emptied cassettes.

Bei dem Ausführungsbeispiel gemäß Fig. 2 besteht der Förderer 10 aus einem einzigen Fördererabschnitt 25, der sich bis zum Träger 16 erstreckt. Der Fördererabschnitt 26 ist Teil des Trägers 16 und mit letzterem hin- und herverschiebbar. Es ist deshalb erforderlich, den Fördererabschnitt 26 so breit auszulegen, daß er sich über beide Stellplätze 17, 18 erstreckt, oder zwei - in Längsrichtung der Umlaufbahn 1 gesehen - hintereinander liegende einzelne Fördererabschnitte 26 im Bereich der Stellplätze 17, 18 anzuordnen.In the exemplary embodiment according to FIG. 2, the conveyor 10 consists of a single conveyor section 25 which extends up to the carrier 16. The conveyor section 26 is part of the carrier 16 and can be pushed back and forth with the latter. It is therefore necessary to design the conveyor section 26 so wide that it extends over both parking spaces 17, 18, or to arrange two individual conveyor sections 26 one behind the other in the region of the parking spaces 17, 18, as seen in the longitudinal direction of the orbit 1.

Aus. Fig. 2 ist deutlich zu entnehmen, daß die Kassetten in übereinander gestapelten Reihen 4, also in Stapeln, angeordnet sind. Die Höhenverstellung der Greifbacken 9 ist entsprechend ausgelegt.Out. 2 clearly shows that the cassettes are arranged in rows 4 stacked one above the other, that is to say in stacks. The height adjustment of the gripping jaws 9 is designed accordingly.

Bei der in Fig. 3 dargestellten Variante der Erfindung ist der verschiebbare Träger 16 nicht mehr über der Umlaufbahn 1 angebracht, sondern in die Befüll- oder Entleerungsvorrichtung 11, 12 verlegt. Darüber hinaus ist die Ausführung der Vorrichtung zum Be- und Entladen identisch mit in Fig. 1 dargestellten, vorstehend beschriebenen Ausführung, so daß sich diesbezüglich eine nochmalige Erläuterung erübrigt.In the variant of the invention shown in FIG. 3, the displaceable carrier 16 is no longer attached above the orbit 1, but is instead moved into the filling or emptying device 11, 12. In addition, the design of the device for loading and unloading is identical to the design described above in FIG. 1, so that a further explanation is unnecessary in this regard.

Aus der Verlegung des Trägers 16 in die Befüll-oder Entleerungsvorrichtung ergibt sich folgende Arbeitsweise:The following procedure results from the laying of the carrier 16 in the filling or emptying device:

Bei der Vorrichtung 5 zum Entladen wird eine mit Dachziegeln gefüllte Kassettenreihe mittels der Greifbacken 9 vom Ofenwagen 2 auf den Förderer 10 umgesetzt. Anschliessend fördert dieser die Kassettenreihe zur Entleerungsvorrichtung 12, in der z.B. der Stellplatz 18 des Trägers 16 sich in Position C) befindet, fluchtend mit dem Förderer 9, um die angeförderte Kassettenreihe aufzunehmen. Während dieser Arbeitsschritte wird eine auf dem Stellplatz 17 (Pos. B) befindliche Reihe gefüllter Kassetten mittels der Greifbacken 22 entleert und die entnommene Ziegelreihe 13 auf den Abführungsförderer 14 übergesetzt. Daraufhin wird der Träger 16 in die gestrichelt angedeutete Lage verschoben, in der der Stellplatz 17 in Position C) mit dem Förderer 10 fluchtet, und der Stellplatz 18, der mit einer Reihe gefüllter Kassetten belegt ist, die Position D) einnimmt.In the device 5 for unloading, a row of cassettes filled with roof tiles is transferred from the kiln car 2 to the conveyor 10 by means of the gripping jaws 9. The latter then conveys the row of cassettes to the emptying device 12, in which e.g. the parking space 18 of the carrier 16 is in position C), aligned with the conveyor 9, in order to receive the row of cassettes being conveyed. During these work steps, a row of filled cassettes located on the parking space 17 (item B) is emptied by means of the gripping jaws 22 and the row of bricks 13 removed is transferred to the discharge conveyor 14. Thereupon, the carrier 16 is moved into the position indicated by dashed lines, in which the parking space 17 in position C) is aligned with the conveyor 10, and the parking space 18, which is occupied by a row of filled cassettes, occupies position D).

Als nächstes wird die auf dem Stellplatz 17 befindliche entleerte Kassettenreihe über den Förderer 10 zur Umlaufbahn 1 zurückbefördert und auf den Ofenwagen übergesetzt, worauf eine weitere Reihe gefüllter Kassetten vom Ofenwagen 2 auf den Förderer 10 übergesetzt und zur Entleerungsvorrichtung 12 befördert wird und auf den Stellplatz 17 des Trägers gelangt. Während dieser Arbeitsschritte wird die auf dem Stellplatz 18 in Position D) befindliche Kassettenreihe entleert. Daraufhin wird der Träger 16 wieder in die mit Vollinien dargestellt Lage verschoben, in der der Stellplatz 18 in Position C) mit dem Förderer 10 fluchtet, und der Stellplatz 17 die Position B) einnimmt.Next, the emptied row of cassettes located on the parking space 17 is conveyed back to the orbit 1 via the conveyor 10 and transferred to the kiln car, whereupon a further row of filled cassettes is transferred from the kiln car 2 to the conveyor 10 and conveyed to the emptying device 12 and to the parking space 17 of the wearer. During these work steps, the row of cassettes located in the parking space 18 in position D) is emptied. The carrier 16 is then moved back into the position shown with solid lines, in which the parking space 18 in position C) is aligned with the conveyor 10, and the parking space 17 assumes the position B).

Nachdem die entleerte Kassettenreihe vom Stellplatz 18 über den Förderer 10 zur Umlaufbahn zurückgeleitet und auf den Ofenwagen 2 übergesetzt ist, wird der Stellplatz 18 in der vorgeschilderten Weise wieder mit einer Reihe gefüllter Kassetten belegt und gleichzeitig die gefüllte Kassettenreihe auf dem Stellplatz 17 entleert.After the emptied row of cassettes is returned from the parking space 18 via the conveyor 10 to the orbit and transferred to the kiln car 2, the parking space 18 is again filled with a row of filled cassettes in the manner described and the filled cassette row at the parking space 17 is emptied at the same time.

Die Arbeitsweise der Vorrichtung 6 zum Beladen der Ofenwagen mit gefüllten Kassettenreihen ist entsprechend, wobei in der Befüllvorrichtung 11 Reihen leerer Kassetten auf die Stellplätze 17, 18 des Trägers 16 übertragen werden und das Befüllen der Kassettenreihen durch Übersetzen der Dachziegel vom Zuführungsförderer 15 mittels der Greifbacken 22 erfolgt.The operation of the device 6 for loading the kiln cars with filled rows of cassettes is corresponding, with 11 rows of empty cassettes being transferred to the parking spaces 17, 18 of the carrier 16 in the filling device, and the filling of the rows of cassettes by translating the roof tiles from the feed conveyor 15 by means of the gripping jaws 22 he follows.

Die Stellplätze 17,18 des in die Befüll- oder Entleerungsvorrichtung 11, 12 integrierten verschiebbaren Trägers 16 können analog dem Ausführungsbeispiel gemäß Fig. 2 in Fortsetzung des Förderers 10 jeweils als Förderer ausgebildet sein.The parking spaces 17, 18 of the displaceable carrier 16 integrated into the filling or emptying device 11, 12 can be designed as a conveyor in a continuation of the conveyor 10, analogously to the exemplary embodiment according to FIG. 2.

Ferner kann der Transport der Kassettenreihen auf dem Förderer 10 auf einer Palette erfolgen.Furthermore, the rows of cassettes can be transported on the conveyor 10 on a pallet.
