The transporting path in this case comprises rolling plates (4) arranged in series in the longitudinal direction of the firing channel and forming two rows (2) and (3) next to each other at a distance apart. The rolling plates (4) are provided with channels (5), which receive balls (6) for carrying and advancing the carriages (7), the channels (5) being arranged in an oval-shaped circuit in the rolling plates (4) for the balls (6). Each row of rolling plates is inclined from the horizontal towards the inside of the transporting path (1), the carriages (7) being given a trapezoidal shape, the flanks of which form a flat angle with the inclination of the rolling plates (4). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Transportbahn in einem Tunnelofen zum Brennen von keramischem Gut, mit welcher Schlitten zum Transport des keramischen Gutes durch den Brennkanal des Tunnelofens geführt werden, wobei die Transportbahn aus in Längsrichtung des Brennkanlas aneinandergereihten Abrollplatten besteht, die mit Rinnen versehen sind und die Kugeln zum Tragen und Weiterbefördern der Schlitten aufnehmen.The invention relates to a transport path in a tunnel furnace for firing ceramic material, with which sled for transporting the ceramic material are guided through the firing channel of the tunnel furnace, the transport path consisting of rolling plates arranged in the longitudinal direction of the firing channel, which are provided with channels and pick up the balls for carrying and transporting the sled.

In der DE-OS 22 20 392 ist eine derartige Transportbahn beschrieben, bei der die die Schlitten tragenden Kugeln mit den Schlitten durch den Brennkanal geführt werden. Die Kugeln werden am Eingang des Brennkanals auf die Abrollplatten gelegt und am Ausgang des Brennkanals von den Abrollplatten abgenommen und wieder zum Eingang des Brennkanals zur erneuten Verwendung zurücktransportiert.DE-OS 22 20 392 describes such a transport path in which the balls carrying the slides are guided through the combustion channel with the sled. The balls are placed on the unwinding plates at the entrance of the firing channel and removed from the unwinding plates at the exit of the firing channel and transported back to the entrance of the firing channel for reuse.

Dieser Rücktransport der Kugeln setzt einen erheblichen baulichen Aufwand für die Erstellung von entsprechenden Maschinen und Transportvorrichtungen voraus.This return transport of the balls requires considerable construction effort for the creation of appropriate machines and transport devices.

Auch sind die Kugeln einem starken Temperaturwechsel ausgesetzt, welches sich nachteilig auf die Lebensdauer der Kugeln auswirkt.The balls are also exposed to a strong temperature change, which has a negative effect on the life of the balls.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Transportbahn in einem Tunnelofen zum Brennen von keramischem Gut zu schaffen, bei der die zum Tragen und Weiterbefördern der Schlitten dienenden Kugeln je nach Standort im Brennkanal annähernd einer gleichbleibenden Temperatur ausgesetzt sind.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a transport path in a tunnel kiln for firing ceramic material, in which the balls used for carrying and conveying the sled are subjected to approximately a constant temperature depending on the location in the firing channel .

Die durch die Erfindung erreichten Vorteile sind darin zu sehen, daß das Auflegen und das Abnehmen der Kugeln von den Abrollplatten und der Rücktransport der Kugeln entfällt; dies wirkt sich Vorteilhaft bei den Investitionskosten aus.The advantages achieved by the invention can be seen in the fact that there is no need to place and remove the balls from the rolling plates and to transport the balls back; this has an advantageous effect on the investment costs.

Da die Kugeln in den ovalförmig angeordneten Rinnen umlaufen und an dem einmal vorgesehen Standort im Bereich einer Abrollplatte verbleiben, werden die Kugeln einer gleichbleibenden Temperatureinwirkung unterworfen,'so daß die Lebensdauer der Kugeln einen höheren Wert erreicht.Since the balls run in the oval-shaped channels and remain at the intended location in the area of a rolling plate, the balls are subjected to a constant temperature effect, so that the life of the balls reaches a higher value.

Ein weiterer Vorteil besteht darin, daß mit einer geringeren Anzahl Kugeln ausgekommen werden kann. Dadurch ergibt sich, daß teures, auf hohe Temperaturen ausgerichtetes und durch Rundschleifen behandeltes Material eingespart werden kann. Die Investitionskosten werden also geringer.Another advantage is that a smaller number of balls can be used. This means that expensive, high-temperature material and cylindrical grinding can be saved. The investment costs are therefore lower.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt

  • Figur 1 eine Teildraufsicht auf die Transportbahn wobei zum besseren Verständnis die Schlitten fortgelassen sind und
  • Figur 2 einen Schnitt durch die Transportbahn mit den zu befördernden Schlitten nach Linie II-II in Figur 1.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. It shows
  • Figure 1 is a partial plan view of the conveyor track with the sled omitted for better understanding and
  • FIG. 2 shows a section through the transport path with the sled to be transported according to line II-II in FIG. 1.

In den Figuren ist eine Transportbahn 1 dargestellt, die in einem Tunnelofen zum Brennen von keramischem Gut angeordnet sein kann. Die Transportbahn 1 besteht aus zwei Reihen 2 und 3 nebeneinanderliegender Abrollplatten 4, die in einem Abstand A voneinander angeordnet sind.A transport path 1 is shown in the figures, which can be arranged in a tunnel furnace for firing ceramic material. The conveyor track 1 consists of two rows 2 and 3 of adjacent rolling plates 4, which are arranged at a distance A from each other.

Die Abrollplatten 4 sind gegenüber der waagerechten zum inneren der Transportbahn 1 hin in einem Winkel B schräggeneigt angeordnet. Die Abrollplatten 4 liegen auf Stützen 9 auf, die entsprechend des Winkels B geneigt ausgebildete Lagerstellen 10 besitzen, die die Abrollplatten 4 aufnehmen. Die Stützen 9 befinden sich auf dem Boden bzw. Sohlzug des Brennkanals. Die Stützen 9 und auch die Abrollplatten 4 können je nach Beanspruchung ohne weiteres ausgewechselt werden.The rolling plates 4 are arranged inclined at an angle B with respect to the horizontal towards the inside of the transport path 1. The rolling plates 4 rest on supports 9 which have bearing points 10 which are inclined according to the angle B and which accommodate the rolling plates 4. The supports 9 are located on the floor or bottom channel of the combustion channel. The supports 9 and the rolling plates 4 can be easily replaced, depending on the load.

Jede Abrollplatte 4 besitzt oberseitig eine Rinne 5, die in Form eines Ovals verläuft. Die Rinnen 5 nehmen Kugeln 6 auf, die in den Rinnen 5 im Rundlauf abrollen.Each rolling plate 4 has a groove 5 on the top, which runs in the form of an oval. The channels 5 take up balls 6 which roll in the channels 5 in a concentric manner.

Die im inneren Bereich 4b der Transportbahn 1 bzw. der Rinnen 5 befindlichen Kugeln 6a tragen Schlitten 7, die ungefähr eine entsprechend der Neigung der Abrollplatten 5 ausgebildete Trapezform aufweisen. Die Flanken 7a des Schlittens 7 bilden mit der Neigung der Abrollplatten 4 einen flachen Winkel C, so daß nur die im inneren Bereich 4b der Transportbahn 1 befindlichen Kugeln 6a mit dem Schlitten 7 in Berührung kommen, während die andereren Kugeln 6 ohne Traglast frei in den Rinnen 5 umlaufen. Auf dem Schlitten 7 ist eine Tragplatte 7b aufgelegt, die das keramische Gut trägt.The balls 6a located in the inner region 4b of the transport path 1 or the channels 5 carry slides 7 which have approximately a trapezoidal shape which corresponds to the inclination of the rolling plates 5. The flanks 7a of the carriage 7 form a flat angle C with the inclination of the rolling plates 4, so that only the balls 6a located in the inner region 4b of the transport path 1 come into contact with the carriage 7, while the other balls 6 freely load into the Run around channels 5. A support plate 7b, which carries the ceramic material, is placed on the carriage 7.

Durch die Bewegung der Schlitten 7 in Richtung des Pfeiles D werden die Kugeln 6 bzw. 6a laufend aus dem inneren Bereich 4b der Transportbahn 1 in den Randbereich 4a und von dort wieder in den Innenbereich 4b der Transportbahn 1 in ständigem Umlauf in den Rinnen 5 gehalten. Sobald die Kugeln 6 aus dem Innenbereich 4b in den Außenbereich 4a gelangt sind, rollen die Kugeln 6, da sie durch den Schlitten 7 nicht belastet sind, von selbst in den Innenbereich 4b zurück, da die Rinnenführung im Randbereich 4a zur Rinnenführung im Innenbereich 4b eine kleine Neigung besitzt.Due to the movement of the carriage 7 in the direction of arrow D, the balls 6 and 6a are kept in constant circulation in the channels 5 from the inner region 4b of the transport path 1 into the edge region 4a and from there again into the inner region 4b of the transport path 1 . Once the balls 6 out of the interior 4b have reached the outer region 4a, the balls 6 automatically roll back into the inner region 4b, since they are not loaded by the carriage 7, since the channel guide in the edge region 4a has a slight inclination to the channel guide in the inner region 4b.

Die einzelnen Abrollplatten 4 können in den Reihen 2 und 3 mit, Lücken hintereinander angeordnet sein, um die infolge der Temperatureinwirkung erfolgende Ausdehnung aufzufangen.The individual rolling plates 4 can be arranged in rows 2 and 3 with gaps one behind the other in order to absorb the expansion that occurs as a result of the temperature effect.
