Description

Hohlgeschirr-Giessvorrichtung mit einer eine oder mehrere in Reihe angeordnete Einzelformen aufweisenden Formeneinheit, die längs der Reihe der Einzelformen in zwei Hälften geteilt ist, und mit einer Greifeinrichtung mit zwei gegeneinander drückbaren Greiforganen, die die Formeneinheit auf zwei zueinander entgegengesetzten Seiten in einer die beiden Hälften der Formeneinheit gegeneinander drückenden Weise erfassen.Hollow tableware casting device with a mold unit having one or more individual molds arranged in a row, which is divided into two halves along the row of individual molds, and with a gripping device with two gripping members that can be pressed against one another, which holds the mold unit on two opposite sides in one of the two halves the mold unit against each other.

Bei einer bekannten Hohlgeschirr-Giessvorrichtung für Keramik, insbesondere Steingut, verläuft die Trennungslinie zwischen den von den Greiforganen erfassten entgegengesetzten Seiten der Formeneinheit, also quer zur Druckrichtung der Greiforgane. Auf diese Weise wird beim Greifen der Formeneinheit auch dem Druckeiner mit Schlicker gefüllten Formeneinheit entgegengewirkt, der die beiden Formhälften auseinanderzudrücken versucht.In a known hollow tableware casting device for ceramics, in particular earthenware, the dividing line runs between the opposite sides of the mold unit which are gripped by the gripping members, that is to say transversely to the direction of pressure of the gripping members. In this way, when the mold unit is gripped, the pressure of a mold unit filled with slip is also counteracted, which attempts to push the two mold halves apart.

Das bekannte Vorgehen hat jedoch den Nachteil, dass entweder mehrere dicht an dicht anliegende Formeneinheiten gleichzeitig mit einer einzigen Greifeinrichtung erfasst werden müssen oder aber der Absand zwischen den einzelnen Formeneinheiten, die auf einem Transportband sich quer zur Transportrichtung erstreckend an die Greifeinrichtung herangeführt werden, mindestens entsprechend dem Raumbedarf eines Greiforgans einschliesslich seiner linearen Verschiebung gewählt werden muss.However, the known procedure has the disadvantage that either several closely-fitting mold units must be gripped at the same time with a single gripping device, or the sand between the individual mold units, which are brought to the gripping device on a conveyor belt extending transversely to the transport direction, at least accordingly the space required for a gripping element, including its linear displacement, must be selected.

Ein Zusammenschluss von mehreren Formeneinheiten zu einer Gesamtform mit einer Vielzahl von Reihen von Einzelformen erlaubt nicht die Verwendung unterschiedlicher Einzelformen. Ausserdem müssten die gegebenenfalls auf einem Förderband herantransportierten zu einer Gesamtform zusammengeschlossenen Formeneinheiten ebenfalls entsprechend der Grösse der Greiforgane und derenVerschiebungsstrecke beabstandet sein.A concentration of more mold units to a G esamtform with a plurality of rows of individual forms does not permit the use of different individual molds. In addition, the mold units possibly brought together on a conveyor belt to form an overall shape would also have to be spaced according to the size of the gripping members and their displacement distance.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Weg aufzuzeigen, wie möglichst viele Formeneinheiten, die gegebenenfalls jeweils unterschiedliche Einzelformen enthalten, pro Zeiteinheit in einer als Fertigungsstrasse ausgebildeten Hohlgeschirr-Giessanlage bearbeitet werden können.The invention is based on the object of demonstrating a way in which as many mold units, which may contain different individual molds in each case, can be processed per unit time in a hollow tableware casting system designed as a production line.

Diese Aufgabe wird bei einer eingangs als bekannt vorausgesetzten Hohlgeschirr-Giessvorrichtung erfindungsgemäss dadurch gelöst, dass die Trennungslinie der Formeneinheit von der einen zu der entgegengesetzten anderen,jew eils von einem Greiforgan erfassten Seite der Formeneinheit verläuft, dass an jeder von einem Greiforgan erfasstenSeite beidseits der Trennungslinie zu ihr schräg verlaufende Angriffsflächen mit entgegengesetzter Neigung vorgesehen sind und dass die Greiforgane jeweils ein Paar vorzugsweise V-förmig in Richtung auf das andere Greiforgan voneinander sich wegerstreckende Greifelemente für eine Anlage an die Angriffsflächen der Formeneinheit aufweisen.This object is achieved according to the invention in a hollow tableware casting device initially assumed to be known in that the dividing line of the mold unit runs from one to the opposite other side of the mold unit, each gripped by a gripping member, on both sides of the dividing line on each side gripped by a gripping member to it obliquely extending engagement surfaces are provided with opposite inclinations and that the gripping members each have a pair of preferably V-shaped gripping elements extending away from each other in the direction of the other gripping member for contact with the engagement surfaces of the mold unit.

Gemäss der Erfindung sind also die Greiforgane in Richtung der Trennungslinie wirksam. Sie pressen aber trotzdem beim Ergreifen einer Formeneinheit deren Hälften zusammen, da sieeilartig an gegenüber der Trennungslinie geneigten Flächen angreifen, so dass ein Teil der von den Greiforganen ausgeübten Kraft quer zur Trennungslinie umgelenkt wird. Das Ergreifen einer Formeneinheit entlang der Trennungslinie erlaubt aber auch ein Anordnen der Formeneinheiten dicht an dicht quer zu den Trennungslinien, also beispielsweise in Förderrichtung eines Bandes. Trotz der dichten Anordnung der Formeneinheiten lässt sich aber jede Formeneinheit dann einzeln entnehmen, so dass es möglich ist, unterschiedliche Formeneinheiten, die unterscheidlich hinsichtlich ihrer Einzelformen sind, in einem derartigen Gesamtsystem zu verwenden. Die dichte Anordnung der Formeneinheiten erlaubt eine maximale Ausnutzung der Fördereinrichtung einer Hohlgeschirr-Giessvorrichtung.According to the invention, the gripping members are effective in the direction of the dividing line. However, when a mold unit is gripped, they still press their halves together, since they act like ropes on surfaces inclined with respect to the dividing line, so that part of the force exerted by the gripping members is deflected transversely to the dividing line becomes. Grasping a mold unit along the dividing line also allows the mold units to be arranged close to one another, transversely to the dividing lines, for example in the conveying direction of a belt. Despite the dense arrangement of the mold units, however, each mold unit can then be removed individually, so that it is possible to use different mold units that differ in their individual molds in such an overall system. The dense arrangement of the mold units allows maximum utilization of the conveying device of a hollow tableware casting device.

Die erfindungsgemässe Greifeinrichtung lässt sich beispielsweise in Umsetz- und Übersetzstationen von Hohlgeschirr-Giessanlagen verwenden, wo die Form von einem Förderband auf ein anderes Förderband gesetzt werden soll, oder in der Ausgiesstation, in der die Formeneinheit erfasst und um 180° zum Ausgiessen des Restschlickers nach der Scherbenausbildung gedreht wird.The gripping device according to the invention can be used, for example, in transfer and transfer stations of hollow crockery casting systems, where the mold is to be placed on a conveyor belt on another conveyor belt, or in the pouring station, in which the mold unit is gripped and rotated through 180 ° to pour out the remaining slip the cullet formation is rotated.

Vorzugsweise sind die schrägen Angriffsflächen für die Greifelemente an den Ecken der ansonsten im wesentlichen rechteckigen Formeneinheit vorgesehen.The oblique engagement surfaces for the gripping elements are preferably provided at the corners of the otherwise essentially rectangular mold unit.

Der Winkel, den die schrägen Angriffsflächen einer Formeneinheit mit der Trennungslinie einschliessen, beträgt vorteilhafterweise 45°.The angle which the oblique contact surfaces of a mold unit form with the dividing line is advantageously 45 °.

Die schrägen Angriffsflächen können prinzipiell auch gekrümmt sein, jedoch wird eine ebene Form der Angriffsflächen bevorzugt.In principle, the oblique engagement surfaces can also be curved, but a flat shape of the engagement surfaces is preferred.

Wird die Greifeinrichtung in einer Ausgeisstation verwendet, so ist in weiterer Ausbildung der Erfindung vorgesehen, dass die Greifeinrichtung um eine senkrecht zu der Linie, entlang welcher die Greiforgane gegeneinander drücken, verlaufende Achse drehbar gelagert ist.If the gripping device is used in a Ausgeisstation, it is provided in a further embodiment of the invention that the gripping device ent by a perpendicular to the line long which press the gripping members against each other, the rotating axis is rotatably mounted.

Further advantages, details and features of the invention emerge from the following description of a preferred exemplary embodiment which is given with reference to the accompanying drawing. In the drawing, steeply represent:

Die Formeneinheit 10, die im Nachfolgenden kurz als Blockform bezeichnet wird, besteht aus Gips. Sie enthält in dem dargestellten Ausführungsbeispiel drei Einzelformen 10a, 10b und 10c, die in einer geradlinigen Reihe angeordnet sind. Die Blockform 10 ist entlang einer Trennungslinie 12, die mittig durch die Einzelformen 10a, 10b und 10c hindurchläuft, in zwei Hälften 10' und 10" teilbar. Zu bemerken ist, dass die Aussenseiten der Blockform 10 im wesentlichen glatt und geradlinig verlaufen. Mit 14 ist ein Überlauftrichter bezeichnet, der den Einzelformen 10a, 10b und 10c zugeordnet ist, die auch über ihn miteinander in Verbindung stehen.Dieser Überlauftrichter, der beim Eingiessen des Schlickers gefüllt wird, hat die Aufgabe, für einen Ausgleich der beim Antrocknen des Schlickers stattfindenden Schrumpfung zu sorgen.The mold unit 10, which will be referred to as a block mold in the following, consists of plaster. In the exemplary embodiment shown, it contains three individual shapes 10a, 10b and 10c, which are arranged in a straight line. The block mold 10 can be divided into two halves 10 ′ and 10 ″ along a dividing line 12 which runs centrally through the individual molds 10a, 10b and 10c. It should be noted that the outer sides of the block mold 10 run essentially smoothly and in a straight line An overflow funnel is designated, which is assigned to the individual molds 10a, 10b and 10c, which are also connected to one another via it. This overflow funnel, which is filled when the slip is poured in, has the task of compensating for the shrinkage occurring when the slip dries on to care.

Ferner sind die Blockformen 10 jeweils mit einem (nicht gezeigten) umlaufenden Spannband versehen, um die beiden Hälften 10', 10" zusammenzuhalten, wenn sie auf einem (nicht gezeigten) Transportband quer zur Trennungslinie 12 herangefördert werden.Furthermore, the block molds 10 are each provided with a circumferential tensioning belt (not shown) in order to hold the two halves 10 ′, 10 ″ together when they are conveyed on a conveyor belt (not shown) transversely to the dividing line 12.

Die Greifeinrichtung weist gegeneinander in Richtung der Trennungslinie 12 einer herangeführten Blockform 10 verschiebbare Greiforgane 16', 16" mit V-förmig voneinander weg sich erstreckenden Greifelementen 18', 18', 18", 18" auf. Diese Greifelemente 18',18' und 18", 18" greifen an schräg zur Trennungslinie 12 der Blockform 10 verlaufende Angriffsflächen 20', 20' und 20", 20" an, wie dies in Fig. 1 dargestellt ist. Die schrägen Angriffsflächen 20', 20' und 20", 20" entstehen durch Abschrägen der Ecken der ansonsten rechteckförmigen Blockform 10. Greifen nun die Greifelemente 18', 18' an den schrägen Angriffsflächen 20', 20' und die Greifelemente 18", 18" an den schrägen Angriffsflächen 20", 20" der Blockform 10 an, so wird die Blockform 10 in optimaler Weise ergriffen und zusammengehalten. Es treten dabei nämlich Kräfte aus allen Richtungen von aussen nach innen auf.The gripping device has gripping members 16 ′, 16 ″ which can be displaced relative to one another in the direction of the dividing line 12 of an approached block mold 10, with gripping elements 18 ′, 18 ′, 18 ″, 18 ″ extending away from one another in a V-shape. These gripping elements 18 ′, 18 ′ and 18 ", 18" act on attack surfaces 20 ', 20' and 20 ", 20" which run obliquely to the dividing line 12 of the block shape 10, as shown in FIG. 1. The oblique attack surfaces 20 ', 20' and 20 ", 20 "are created by chamfering the corners of the otherwise rectangular block shape 10. Now grip the gripping elements 18 ', 18' on the oblique engagement surfaces 20 ', 20' and the gripping elements 18", 18 "on the oblique engagement surfaces 20", 20 "of the block shape 10, the block shape 10 is gripped and held together in an optimal manner, namely, forces arise from all directions from the outside inwards.

Wie man leicht aus Fig. 1 entnimmt, können die Blockformen 10 auf Stoss quer zur Trennungslinie 12 hintereinander angeordnet werden, ohne dass sie sich gegenseitig stören, wenn sie einzeln ergriffen werden sollen. Dies liegt daran, dass aufgrund des schrägen Verlaufs der Angriffsflächen 20', 20' und 20", 20" trotz der Anlage der Blockformen 10 auf Stoss ein gewisser Spielraum für die Greifelemente 18', 18' und 18", 18" quer zur Trennungslinie geschaffen worden ist.As can easily be seen in FIG. 1, the block molds 10 can be arranged in a butt joint transversely to the dividing line 12 without them interfering with one another if they are to be gripped individually. This is due to the fact that due to the oblique course of the attack surfaces 20 ', 20' and 20 ", 20" in spite of the block molds 10 abutting, there is a certain scope for the gripping elements 18 ', 18' and 18 ", 18" across the dividing line has been created.

Ferner ist ohne weiteres aus Fig. 1 ersichtlich, dass die Blockformen 10 auch in ihren Aussenabmessungen sich innerhalb eines gewissen Toleranzbereiches unterscheiden können, vornehmlich in ihrer Breite und in ihrer Länge. Der die Gleitelemente 18', 18' bzw. 18", 18" verbindende Abschnitt der Greiforgane 18', 16" muss nämlich nicht in Anlage an die senkrecht zur Trennungslinie 12 verlaufenden Endflächen der Blockform 10 kommen.Furthermore, it is readily apparent from FIG. 1 that the block shapes 10 can also differ in their outer dimensions within a certain tolerance range, primarily in their width and length. The section of the gripping members 18 ', 16 "connecting the sliding elements 18', 18 'or 18", 18 "does not have to come into contact with the end faces of the block mold 10 which are perpendicular to the dividing line 12.

In diesem Zusammenhang sei auch bemerkt, dass es auch möglich ist, ohne sich vom Prinzip der Erfindung zu entfernen, anstelle der trapezartigen Endabschnitte der Blockform 10 eine gekrümmte, bogenförmige Ausbildung der Endabschnitte vorzusehen. Entsprechend würden dann die Greifelemente 18', 18' und 18", 18" verlaufen. Auch hier wird die in Richtugn der Trennungslinie 12 wirkende Kraft zum Teil quer zur Trennungslinie umgelenkt.In this context, it should also be noted that it is also possible, without departing from the principle of the invention, to provide a curved, arcuate configuration of the end sections instead of the trapezoidal end sections of the block mold 10. The gripping elements 18 ', 18' and 18 ", 18" would then run accordingly. Here, too, the force acting in the direction of the dividing line 12 is partly diverted transversely to the dividing line.

Die Greiforgane 16', 16" sind auf eine r Führungsstange 22 verschiebbar, die quer zu einer Welle 24 befestigt ist, die ihrerseits in einem Lager 26 drehbar gelagert ist. Das Lager 26 ist an einer zur Führungsstange 22 parallelen Tragstange befestigt, die in vertikalen Führungsstangen 30 verschiebbar ist. Die vertikalen Führungsstangen 30 sind über Rollen 31 an Schienen 32 verschiebbar gelagert (s. auch Fig. 2). Auf diese Weise kann die Greifeinrichtung eine Blockform erfassen, anheben, seitlich verschieben, sich um 1800 drehen, weiter verschieben und sie absetzen. Ein solcher Bewegungsablauf, der mit der erfindungsgemässen Greifeinrichtung erzielt werdenkann, ist in der Ausgiesstation einerHohlgeschirr-Giessanlage von grossem Vorteil, wo die auf einem Transportband ankommenden Blockformen erfasst, angehoben und seitlich vom Transportband weggeführt werden,dann um 1800 zum Ausgiessen des Schlickers gedreht werden und dann weiter seitlich verschoben und auf dem Kopf stehend zum Abtropfen des Restschlickers auf ein zum ersten Förderband paralleles Förderband abgesetzt werden. Das zweite Förderband verläuft dabei in der entgegengesetzten Richtung wie das erste Förderband. Auf diese Weise wird das Ausgiessen der Blockformen geschickt mit einem Umsetzen der Blockformen von einem Förderband auf ein anderes Förderband verbunden.The gripping members 16 ′, 16 ″ can be displaced onto an r guide rod 22 which is fastened transversely to a shaft 24, which in turn is rotatably mounted in a bearing 26. The bearing 26 is fastened to a support rod parallel to the guide rod 22, which in vertical guide rods 30 is slidable. the vertical guide rods 30 are slidably mounted on rollers 31 on rails 32 (s. also FIG. 2). in this way, the gripping means detect a block form, lifting, moving laterally, rotate by 180 0, move further and they settle. such a sequence of movements can be achieved with the inventive gripping means are in the Ausgiesstation a hollow crockery-casting machine of great advantage where the arriving on a conveyor belt block shapes detected, is raised and carried away laterally from the conveyor belt, then to 180 0 for pouring of the slip are rotated and then shifted further sideways and upside down to the drainer of the remaining slip are placed on a conveyor belt parallel to the first conveyor belt. The second conveyor belt runs in the opposite direction to the first conveyor belt. In this way, the pouring of the block molds is skillfully combined with a transfer of the block molds from one conveyor belt to another conveyor belt.
