Abstract:
An apparatus for handling sheet-like articles, in particular enclosures in an envelope-filling station for mail-processing machines, having a conveying path (2), over which the sheet-like articles are conveyed in a state in which they rest on the conveying-path surface, having an actuating arrangement (12, 13, 14, 15, 16, 21, 26, 28, 29, 31, 32), which has a carrier (9) which, by means of a drive mechanism (21, 26, 28, 29, 31, 32) of the actuating arrangement, can be moved back and forth, parallel to the conveying direction, over the conveying-path surface such that at least part of the carrier (9) is guided approximately rectilinearly over the conveying-path surface, and having push-in fingers (11), which are articulated on the carrier and, in a guide-controlled manner, are lowered onto the conveying-path surface in the operating stroke and are raised from the conveying-path surface in the return stroke, wherein the drive mechanism has a crankshaft (28), a crank (27) and a connecting rod (26) which, on the one hand, is mounted on the crank and, on the other hand, is in coupling connection with a drive lever (12, 13) of the actuating arrangement for the purpose of moving the carrier (9), and in that fastened on the crankshaft (28) is an elliptical toothed-belt pulley (29) which is coupled, via a toothed belt (31), to a continuously driven, round toothed-belt drive pulley (32).
