19 Claims

1. Device for conveying media, by which conveyed media may optionally be fed to various conveying routes, various delivery stacks being provided in particular at the end of the conveying routes, comprising:

at least one suction belt conveying module comprising

multiple continuously revolving suction belts separated at a distance,

wherein each suction belt is configured to exert a negative pressure on the underside of a medium to be conveyed and to convey the medium from the start to the end of the suction belt conveying module,

and wherein the suction belts are guided by means of mutually spaced deflection rollers at an ingress or egress ends of the suction belt conveying module all being positioned on a rotational axis,

and wherein the deflection rollers at an ingress or egress end of one suction belt conveying module are situated at least partially between deflection rollers at an egress or ingress end of an adjacent suction belt conveying module;

at least one switch point conveying module being designed as a mechanical switch point in order to reroute a conveyed medium in its conveying route;

wherein a conveying path is composed, at least in some places, of at least two conveying modules, between which a medium may be transferred;

wherein at least two guide devices are provided between the at least two conveying modules to support transfer of a medium between the conveying modules, and

wherein the guide device is configurable to modify a conveying speed of a medium between the conveying modules, for which purpose a conveying speed of the guide device is matchable to the speeds of the adjacent conveying modules during a sheet transfer.
