Abstract: A roller conveyor having side wings spaced apart from each other for accommodating rollers that are arranged between these side wings successively in the direction of conveyance. These rollers are rotatably supported at both ends by trunnions extending into these rollers on their face sides, and are driven by a motor. In addition, at least one roller is in driving connection via a gearing with a driving motor arranged on a side wing on the driving side. In this case, the driving motor may be designed in the form of a bow-like section which is open on the side facing away from the rollers. In this case, the driving motor and the gearing, may be combined in a geared motor, and are accommodated within the box-like section.

Abstract: The sorting system comprises a sorting line with ejection stations successively arranged along the line. There is a conveying system guided along the sorting line and having a sorting device successively arranged as well. Each sorting device has a conveyor belt drivable transversely to the sorting line for receiving a parceled article chargeable in a loading station, and for the controlled ejection of the article in an ejection station. The drive of the conveyor belts of the sorting devices takes place purely by mechanical driving means. First driving means are arranged in the region of each ejection station, and are selectively engageable with second driving means of a sorting device. The first driving means cooperates with the second driving means when the respective sorting device passes the first driving means. The first and the second driving means are preferably cooperate by friction grip.

Abstract: Sorting devices are successively guided along a sorting line and driven by means of a conveyor system. Each sorting device has a running carriage with running rollers guided in the sorting line's guide rails. In addition, the sorting device contains a means for receiving and ejecting individual parceled articles sent from a loading station. The conveyor system comprises a chain having chain links with flat undersides which are movably connected to each other. The chain links are rigidly connected to each running carriage of the sorting devices and project beyond these sorting devices in a transport direction. The joints between successive chain links are each bridged on their underside by a pre-tensioned leaf spring. The driving means is a friction wheel drive with a friction wheel engaging the chain links on their undersides. In an alternative embodiment of the invention, one chain link is rigidly connected to each of the running carriages of the sorting devices.

Abstract: Randomly delivered parcels are singled and/or sorted with a central separator which receives a random stream of parcels from a first conveyor. The parcels are removed in single file from the central separator with a second conveyor. The central separator has a semicircular belt curve with a conveyor belt incoming at an incoming-side curve radius and outgoing at a diametrically opposite, outgoing-side curve radius. The first conveyor discharges the parcels randomly into the semicircular belt curve. The second conveyor for removing singled parcels adjoins the belt curve at the outgoing-side curve radius and at a periphery of the belt curve. A return device returns to the belt curve any parcels not directly removed from the belt curve in singled condition. The return device is disposed adjacent the diametrically opposite curve radii and adjacent the second conveyor.
