Abstract
The invention provides an improved accumulating conveyor having a frame with a plurality of roller carriages mounted transversely. Each of the roller carriages comprises a pair of spaced end portions and a connecting portion connecting a lower part of these end portions. A pressure roller is rotatably mounted in a lower portion of each roller carriage, and a conveyor roller is rotatably mounted in an upper portion, parallel to and spaced from the pressure roller. An endless belt is mounted on the frame, and is positioned to pass between the pressure rollers and the conveyor rollers, the belt having a thickness less than the distance between the conveyor and pressure rollers. The belt has a thickened portion which has a thickness at least equal to the distance between the pressure and conveyor rollers, so that passage of the thickened portion causes rotation of these rollers. An intermittent drive force is thereby delivered to the conveyor rollers, and the presence of an article on the conveyor, or the movement of an article along the conveyor, causes the roller carriages to tilt into engagement with the drive belt. Stoppage of articles on the conveyor causes the carriages to tilt i…
