Embodiment Construction

[0023] As shown in Figure 1, the alignment device consists of a horizontally oriented endless base belt 1 with a driven, guided by a turn roller 6 and two vertically oriented endless belts driven at the same speed. Side guide belt 2,3 is formed. In this case, a guide belt 2 as a reference side web is guided by stationary guide rollers 8 , 9 , wherein the guide rollers 8 , 9 are oriented such that the reference side web 2 is inclined in the conveying direction. The other guide strip 3 has a defined minimum distance from the reference side strip 2 when the conveying path is empty, which ensures that thin, curled loose mail items 5 are not jammed or folded. The other guide belt 3 is arranged at the infeed and outfeed by a specific oscillating combination (Schwingenkombination) 7, 10, 11 and 15, 16, 17 in such a way that the thick The mail piece 4 is deflected passively and thus orientated on the second guide belt 2 . The length of the alignment device and the selected gap betwe...

Abstract

The invention relates to a device for orienting flat items of mail towards a narrow edge. Said device comprises a U-shaped conveying channel (3), including a base belt (1) and two vertically oriented, lateral guiding belts (2, 3), a lateral guiding belt (2) being inclined towards the direction of transport as a lateral reference belt. Said lateral reference belt (2) on which the items of mail (4, 5) are transported into the conveying channel in an oriented manner is guided via locally stationary deflection rollers (8, 9). The other guiding belt (3) is guided by means of resiliently received pression deflection rollers (7, 17) in such a manner that the conveying channel has a defined minimum channel width and that, when items of mail (4) are present in the conveying channel that are thicker than the minimum channel width, the other guiding belt (3) deviates outwards against the spring force of the deflection roller bearing to a degree corresponding to the respective thickness of the item, the other guiding belt (3) having a smaller coefficient of friction than the lateral reference belt (2).

Description

technical field [0001] The invention relates to a device for aligning a narrow side of a flat mail piece according to the preamble of claim 1 . Background technique [0002] In the input section of the mail sorting machine, the mail piles are automatically sorted (vereinzelt) by pulling out the standing mail that is at the forefront at that time. The individual mail pieces are then conveyed one after another in a vertical state into processing equipment such as address readers and printers. Here, the mailpieces can neither be rotated nor moved up and down on the processing device. In this case, however, the mail usually travels through an alignment section (Ausrichtstrecke) after separation. [0003] Alignment sections are described in GB921679 and DE19528829C2, in which the mail is forced to be guided in an upright position, wherein the alignment is achieved by obliquely set rollers pressed by the mail. [0004] In DE1116602A, DE3709659C2 and FR2692565A1 the alignment se...
