Description

Die Erfindung betrifft eine Abhebevorrichtung zum Ablegen eines auf einer Presse geformten Formlings aus einem bildsamen Material, wie Ton, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a lifting device for depositing a molded article made of an imaginable material, such as clay, on a press, with the features of the preamble of claim 1.

Bei einer Abhebevorrichtung dieser Art (DE-AS 15 84 671) wird zum Zwecke des Ablegens des Formlings auf einer Unterlage die Saugplatte mittels der ersten Hubvorrichtung beschleunigt, was zur Beschädigung des noch weichen Formlings aufgrund "unsanften" Ablegens auf der Unterlage, wie einem Rähmchen eines Trockenträgers, führen kann.In a lifting device of this type (DE-AS 15 84 671), the suction plate is accelerated by means of the first lifting device for the purpose of depositing the molding on a base, which damages the still soft molding due to "rough" placement on the surface, such as a frame of a dry carrier.

Eine ähnliche Abhebevorrichtung zum Abheben und Ablegen von Ziegelformlingen ist aus der DE 42 25 915 C1 bekannt.A similar lifting device for lifting and depositing bricks is known from DE 42 25 915 C1.

Der Erfindung liegt die Aufgabe zugrunde, eine Abhebevorrichtung der im Oberbegriff des Anspruchs 1 beschriebenen Art so auszubilden, daß ein sanftes Ablegen der Formlinge ohne die Gefahr von deren Beschädigung beim Ablegen gewährleistet wird.The invention has for its object to provide a lifting device of the type described in the preamble of claim 1 so that a gentle placement of the moldings is ensured without the risk of their damage when being placed.

Zur Lösung dieser Aufgabe dient Patentanspruch 1.Claim 1 serves to achieve this object.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Die Erfindung ist im folgenden anhand schematischer Zeichnungen an einem Ausführungsbeispiel mit weiteren Einzelheiten näher erläutert.The invention is explained below with reference to schematic drawings of an embodiment with further details.

a lifting device according to the invention in a second position after depositing the molding.

In den beiden Figuren, welche die Presse in zwei unterschiedlichen Betriebsstellungen der Abhebevorrichtung zeigt, ist die Presse insgesamt mit dem Bezugszeichen 2 bezeichnet. Die Abhebevorrichtung hat ein Querjoch 4, an dem mittig ein Zylinder 6 einer doppelt wirkenden pneumatischen oder hydraulischen Kolben-Zylindervorrichtung 9 vertikal hängend befestigt ist. An der Kolbenstange 8 des zugehörigen Kolbens 10 ist unten eine Platte 12 in einer Führung 14 an der Abhebevorrichtung vertikal auf- und abbewegbar angeordnet.In the two figures, which shows the press in two different operating positions of the lifting device, the press is generally designated with the reference number 2. The lifting device has a transverse yoke 4, on the center of which is a cylinder 6 of a double-acting pneumatic or hydraulic piston-cylinder device 9 vertically hanging attached. On the piston rod 8 of the associated piston 10, a plate 12 is arranged vertically up and down in a guide 14 on the lifting device.

Die Platte 12 trägt ihrerseits einen Aufnahmekörper 16 mit einem Luftanschluß 22 für Saug- bzw. Druckluft eines insgesamt mit dem Bezugszeichen 18 bezeichneten Saugkopfes. Zu diesem Saugkopf 18 gehört ein unter der Platte 12 auswechselbar befestigter Messerrahmen 20, eine Saug- oder Ausstoßplatte 24, welche von Bohrungen 26 zum Durchlassen von Saug- bzw. Druckluft durchsetzt ist, und ein Zylinder 28 einer weiteren Kolben-Zylindervorrichtung 30, die einen Kolben 32 mit Kolbenstange 34 hat. Die Kolbenstange 34 ist an der Oberseite der Saugplatte 24 befestigt.The plate 12 in turn carries a receiving body 16 with an air connection 22 for suction or compressed air of a suction head, generally designated by the reference numeral 18. This suction head 18 includes a knife frame 20 which is interchangeably fastened under the plate 12, a suction or ejection plate 24, which is penetrated by bores 26 for the passage of suction or compressed air, and a cylinder 28 of a further piston-cylinder device 30, which one Has piston 32 with piston rod 34. The piston rod 34 is attached to the top of the suction plate 24.

Die Kolben-Zylindervorrichtungen 9, 30 sind vertikal miteinander fluchtend angeordnet.The piston-cylinder devices 9, 30 are vertically aligned with one another.

Mit 36 ist ein vorher in der Presse geformter Formling bezeichnet, der in Rähmchen 38 auf einer in Pfeilrichtung A getaktet bewegbaren Rahmenbahn 40 abzulegen ist.With 36 a previously formed in the press is designated, which is to be placed in a frame 38 on a movable in the direction of arrow A frame web 40.

Mit der beschriebenen Vorrichtung wird wie folgt gearbeitet:
In der Betriebsstellung gemäß Fig. 1 befindet sich der Saugkopf 18, dessen Raum 25 unter Unterdruck steht, mit unter der Saugplatte 24 gehaltenen Formling 36 in der gezeigten Stellung, in welcher der Formling einen geringfügigen Spalt s zur Oberseite der Rahmenbahn 40 hat. In dieser Stellung ist der Kolben 32 in den Zylinder 28 ganz eingefahren, während der Kolben 10 im Zylinder 6 fast ganz ausgefahren ist. Die Platte 12 befindet sich somit nahe ihrer untersten Stellung, während sich die Saugplatte 24 in ihrer bezüglich des Aufnahmekörpers 16 obersten Stellung befindet.The device described works as follows:
In the operating position according to FIG. 1, the suction head 18, the space 25 of which is under negative pressure, is with the molding 36 held under the suction plate 24 in the position shown, in which the molding has a slight gap s to the top of the frame web 40. In this position, the piston 32 is fully retracted into the cylinder 28, while the piston 10 in the cylinder 6 is almost fully extended. The plate 12 is thus close to its lowest position, while the suction plate 24 is in its is in the uppermost position with respect to the receiving body 16.

Die Fig. 2 zeigt die Stellung, in welcher der Formling 36 auf der Rahmenbahn 40 in einem Rähmchen 38 gerade abgelegt ist. Zum Ablegen muß der Formling von dem Messerrahmen 20 ganz freikommen. Zu diesem Zweck hat unmittelbar vor dem Ablegen der Kolben 32 im Zylinder 28 seinen Ausstoßhub nach unten um die Strecke X durchgeführt. Gleichzeitig ist durch Betätigung des Kolbens 10 des Zylinders 6 dieser Kolben 10 zusammen mit der Platte 12 und dem daran hängenden Saugkopf 18 um den gleichen Hub X nach oben gefahren. Dabei hat die Platte 12 den Aufnahmekörper 16 wiederum um den gleichen Hub X nach oben mitgenommen, wodurch auch der Messerrahmen 20 relativ zur Saugplatte 24 um den Hubweg X nach oben gefahren ist, um den Formling 36 zur Ablage freizugeben. Diese Ablage erfolgt dann durch Erhöhen des Druckes der Druckluft von Unterdruck auf Überdruck in dem Raum 25, damit die Haftung des Formlings 7 an der Saugplatte 24 überwunden wird und somit der Formling 7 aufgrund seiner Schwerkraft um den kleinen Weg s herabfällt. Dieser Weg s kann beliebig klein (bis zu Null) gemacht werden.FIG. 2 shows the position in which the molding 36 has just been placed on the frame track 40 in a frame 38. The mold must be completely released from the knife frame 20 for depositing. For this purpose, immediately before the pistons 32 were placed in the cylinder 28, they carried out their downward stroke by the distance X. At the same time, by actuating the piston 10 of the cylinder 6, this piston 10, together with the plate 12 and the suction head 18 attached to it, has moved upwards by the same stroke X. The plate 12 has in turn taken the receiving body 16 upwards by the same stroke X, as a result of which the knife frame 20 has also moved upwards by the stroke X relative to the suction plate 24 in order to release the molding 36 for storage. This storage is then carried out by increasing the pressure of the compressed air from negative pressure to positive pressure in the space 25, so that the adhesion of the molded article 7 to the suction plate 24 is overcome and thus the molded article 7 falls by the small distance s due to its gravity. This path s can be made arbitrarily small (up to zero).

Auf diese Weise ist ein sanftes Ablegen des noch weichen Formlings auf der Rahmenbahn 40 unter Ausschließen jeglicher Beschädigungsgefahr gewährleistet.In this way, a gentle placement of the still soft molding on the frame web 40 is guaranteed, excluding any risk of damage.

Beide Kolben-Zylindervorrichtungen 9, 30 haben getrennte Druckmittelzufuhren zu ihren beiden Zylinderräumen, die hier nicht dargestellt sind, sowie eine gemeinsame, ebenfalls nicht dargestellte Steuervorrichtung, welche den Betrieb des Anhebens des Kolbens 10 und des gleichzeitigen Absenkens des Kolbens 32 um den gleichen Hub X synchronisiert.Both piston-cylinder devices 9, 30 have separate pressure medium supplies to their two cylinder spaces, which are not shown here, and a common control device, also not shown, which controls the operation of lifting the piston 10 and simultaneously lowering the piston 32 by the same stroke X synchronized.

Aufgrund der Abnehmbarkeit des gesamten Saugkopfes von dem Aufnahmekörper 16 läßt sich die Saugkopf-Wechselzeit auf ein Minimum reduzieren. An dem Aufnahmekörper 16 können unterschiedliche Saugköpfe entsprechend den unterschiedlichen zu formenden Ziegeln (Flächenziegel, Lüfterziegel, Firstanschlußziegel, Ortgangziegel) ohne weiteres mit einer hier nicht dargestellten Schnellspannvorrichtung angebracht werden.Because the entire suction head can be removed from the receiving body 16, the suction head change time can be reduced to a minimum. Different suction heads corresponding to the different bricks to be shaped (flat tiles, ventilating tiles, ridge connecting tiles, verge tiles) can easily be attached to the receiving body 16 with a quick release device, not shown here.
