Description
KAISERLICHESIMPERIAL
PATENTAMT/PATENT OFFICE /
Bei den bisher ausgeführten, stoßfrei arbeitenden Förderrinnen ist vielfach die nachteilige Wirkung vorhanden, daß das Fördergut während des letzten Teiles des Rückganges der Förderrinne mit der Rinne zurückgeht. In the case of the hitherto executed, smoothly working conveyor troughs, the disadvantage is often the one There is an effect that the conveyed material goes back with the trough during the last part of the decline in the conveyor trough.
Dies läßt sich auch bei den bekannten Antrieben nie vermeiden, weil das Gut in der Rinne relativ zur Rinne in Ruhe sein muß,This can never be avoided even with the known drives, because the good in the The gutter must be at rest relative to the gutter,
ίο ehe der neue Vorwärtsgang beginnt. Da es aber praktisch unmöglich ist, das Fördergut genau im Augenblick des neuen Hubbeginnes zur Ruhe zu bringen, so muß das Gut stets zur Ruhe kommen vor Hubbeginn, d. h. also, während sich die Rinne selbst nach rückwärts bewegt. Das Fördergut und die Rinne gehen dann gleichmäßig zurück. Dies bedingt natürlich einen Verlust an Fördervorschub und einen größeren Kraftverbrauch.ίο before the new forward gear begins. Because it but it is practically impossible to get the conveyed goods exactly at the moment of the new start of lifting To bring it to rest, the goods must always come to rest before the start of lifting, d. H. so, while the gutter itself moves backwards. The conveyed goods and the channel go then evenly back. This of course causes a loss of feed rate and greater power consumption.
Diese nachteilige Wirkung läßt sich bei Förderrinnen, welche durch einen Daumen oder eine unrunde Scheibe angetrieben werden , leicht gemäß der Erfindung dadurch vermeiden, .daß man das Stück α b des Daumens (Fig. 1) als Kreisbogen um den Mittelpunkt c der Antriebswelle ausbildet. Wenn der Punkt α der Daumenscheibe an der Rolle d anliegt, welche durch einen Hebel f und die Schubstange g die Rinne antreibt, so beginnt der Vorwärtsgang der Rinne, bis der Punkt h an der Rolle d anliegt. Alsdann wird die Rinne entsprechend der Scheibenkurve /; b durch die bei dem Vorwärtsgange gespannte Feder k zurückgezogen und hat, sobald die Rolle d an den Punkt b des Daumens oder der Scheibe gekommen ist, ihre Anfangslage wieder erreicht. Während der Drehung der Antriebswelle um den Winkel b c α steht die Rinne still, und während dieser Zeit kann das Gut in der Rinne zur Ruhe kommen, ohne daß es mit der Rinne irgendwelche Rückwärtsbewegung ausführt.This disadvantageous effect can easily be avoided according to the invention in conveying troughs which are driven by a thumb or a non-circular disc by forming the piece α b of the thumb (Fig. 1) as a circular arc around the center c of the drive shaft. When the point α of the thumb disk rests against the roller d , which drives the channel through a lever f and the push rod g , the forward movement of the channel begins until the point h rests against the roller d. Then the channel is according to the disc curve /; b is retracted by the spring k tensioned during the forward movement and has reached its starting position again as soon as the roller d has come to point b of the thumb or the disk. During the rotation of the drive shaft through the angle bc α , the channel stands still, and during this time the material can come to rest in the channel without it executing any backward movement with the channel.
Die Bewegung der Rinne entsprechend der Daumenkurve kann natürlich auch auf andere Weise als durch Federkraft erfolgen, z. B. durch Gewicht, durch Gegendaumen oder dadurch, daß man die Rolle d oder dergl. in einer vertieften Rinne der unrunden Scheibe zwangläufig führt.The movement of the groove according to the thumb curve can of course also take place in other ways than by spring force, e.g. B. by weight, by counter-thumb or by the fact that the role d or the like. In a recessed groove of the non-circular disc inevitably leads.
