Problems solved by technology

The disadvantage of the system described above is that when the tires are placed opposite each other across the main conveyor, it is very difficult to transfer them to the exit conveyor

Embodiment Construction

[0017] Figure 1 illustrates a conveyor system embodying features of the present invention. The main conveyor 10 defining the main conveying path 12 is interrupted by gaps 14 . The upstream conveyor 16 is separated by the gap from a downstream conveyor 18 which receives conveyed items, such as tires 20 , from the upstream conveyor. The articles are conveyed along the main conveying path on the top article conveying surface 24 of the conveyor in the direction of arrow 22 . The main conveyor is preferably realized as a belt conveyor. In this embodiment, the upstream conveyor includes a conveyor belt 26 that loops around a drum or sprocket set 28 mounted on a drive shaft 30 . A drive motor 32 connected to the drive shaft turns the sprocket set and drives the upstream conveyor belt in the direction of arrow 22 . The other end of the upstream conveyor belt loops around an idler shaft and sprocket set (not shown, but similar to the shaft and sprocket set now discussed for the down...

Abstract

The present invention provides a sorting conveyor system in which a main conveyor (10) is intersected by one or more cross conveyors (34) forming sorting stations at one or more gaps (14) along a main conveying path (12). The cross conveyor (34) includes a roller-top belt (36) having rollers (50) extending outward of a top article-supporting side (52) and arranged to rotate about axes (54) perpendicular to the main conveying path (12). The cross conveyor (34) includes a bidirectional drive (38) to selectively advance the roller-top belt in one of two opposite directions to discharge articles (20) transferred onto the cross conveyor in the gap off the side of the main conveying path. The cross conveyor also serves as a low-friction roller-top bridge when the roller-top belt (36) is stopped. The bridge allows articles to cross the gap from an upstream portion (16) of the main conveyor to a downstream portion (18).

Description

technical field [0001] The present invention relates generally to power driven conveyors, and more particularly to sorting systems that use roller-top conveyor belts to divert items from one side or the other of a main conveyor. Background technique [0002] In the tire industry, finished tires leave the inspection area in a mishmash of types and sizes. Usually the tires are sorted automatically, marking the type or size using bar codes or colored bar codes. After being transported onto a sorting conveyor, the tires are identified by barcode or color line code readers, or sometimes even by a human operator who recognizes the tire type and presses the appropriate identification button. Once an identified tire has passed the appropriate exit of the sorting conveyor for that type of tire, the tire is moved laterally 90° to an exit conveyor which transfers the tire to the appropriate palletizing or storage station. A typical sorting system uses a complex set of narrow conveyor...
