The invention proposes a suspension-type conveying arrangement in the case of which conveyable-article carriers (1) are supported, by way of running rollers (9) on guide rails (3) for movement along a conveying route. Arranged on a drag chain/drive chain (15) guided along the conveying route are driver elements (17), preferably brush elements (17), which can be moved between a driving position and a non-driving position. The invention proposes various concepts in order, in the case of a build-up of conveyable-article carriers (1), to transfer the driver elements (17) into the non-driving position, with the result that they act on the built-up conveyable-article carriers (1) at most to a slight extent, if at all. In the driving position, it is possible for driver elements (17) to act on the conveyable-article carriers (1) in order to drive them along the conveying route.
A conveying arrangement, in particular suspension-type conveying arrangement, having rails (3) for guiding conveyable-article carriers (1), equipped with running rollers (9), along a conveying route, having a drive belt (15) which is driven in circulation about diverting means, is guided along the conveying route, at least in certain regions, by means of a guide arrangement (19) and has driver elements (17) which are arranged on it and, in a driving position, are suitable, and envisaged, for driving rail-guided conveyable-article carriers (1) along the conveying route, and having means (29) for stopping conveyable-article carriers in a build-up region of the conveying route as the drive belt (15) continues running, characterized in that the conveying arrangement has position-changing means (32) which can be activated in a controlled manner and are intended for transferring driver elements (17) of the drive belt (15) from their driving position into a non-driving position in the build-up region, it being possible for the driver elements (17) located in the non-driving position, if appropriate, only to engage to a slight extent, if at all, and with easily yielding action with built-up conveyable-article carriers (1).
A conveying arrangement, in particular suspension-type conveying arrangement, having rails (3) for guiding conveyable-article carriers (1), equipped with running rollers (9), along a conveying route, having a drive belt (15) which is guided, at least in certain regions, along the conveying route and has driver elements (17) which are arranged on it and, in a driving position, are suitable, and envisaged, for driving rail-guided conveyable-article carriers (1), characterized in that the driver elements (17) on the drive belt (15) can be transferred in each case from the driving position into a non-driving position, and in that each driver element (17) is assigned a respective build-up sensor (60) which is carried along on the drive belt (15) and is intended for detecting built-up conveyable-article carriers (1), the build-up sensors (60) being designed for transferring the driver elements (17) assigned to them into the non-driving position when a build-up of conveyable-article carriers is detected.
The conveying arrangement as claimed in one of the preceding claims, characterized in that the drive belt (15) is a drive chain, in particular plate link chain with driver elements arranged thereon.
The conveying arrangement as claimed in one of the preceding claims, characterized in that the driver elements (17) have driver fingers which can be deflected with elastic yielding action.
The conveying arrangement as claimed in one of the preceding claims, characterized in that the driver elements (17) comprise brush elements with driver bristles.
The conveyable-article carrier as claimed in one of the preceding claims, characterized in that individual driver elements always remain in the driving position.
