Problems solved by technology

The measure proposed in EP 0 185 395 B1 prevents wedging of the sheet in the selection gap, but does not ensure that the leading edge of the uppermost banknote to be selected is closest to the selection gap

Embodiment Construction

[0027] figure 1 The apparatus for picking out sheets according to the first embodiment is schematically shown. In the sheet stock 1 , a stack 2 of banknotes, here comprising only seven banknotes by way of example, rests against a support plate 3 . The support plate 3 has a feed wheel 4 with a friction lining 5 extending through it, by rotation in the direction of the arrow, the sheet stack 2 (in particular the lowermost sheet 6 which rests directly on the feed wheel 4) Transfer to the feed gap 7 opposite the stop surface 8 of the stack magazine 1 . The pick-off roller 9 grips the leading edge of the banknote lying flat against the feed gap 7, the friction section 10 having a much greater coefficient of friction than the remaining circumference of the pick-off roller. The banknotes thus caught are guided to the downstream transport system 11 by the rotation of the pick-off roller 9 in the direction of the arrow, figure 1 The first transport nip of the transport system 11 is ...

Abstract

The invention relates to a method for separating sheet-type products in which multiple withdrawals are avoided. To this end, a retaining device (15, 17), not only on one side but also on the other side of the sheet (14) to be separated, ensures that sheet-type product torn together with the sheet to be separated is retained. While the first retaining device (12) is located opposite the separating device with a separating gap (13) therebetween and is constantly active, the second retaining device (15, 17), in front of or in the separating gap, works from the other side of the separating gap (13) and is activated once the sheet to be separated is reliably seized by the separating device and is deactivated when it leaves the separating gap (13).

Description

technical field [0001] The invention relates to a method for avoiding multiple selections during singling of sheet material, and a corresponding device for singling of sheet material, in particular a banknote processing machine, in which banknotes to be processed are in stacks ground to the banknote processing machine. Background technique [0002] For this purpose, such banknote processing machines usually have a pocket for receiving stacks of banknotes. The banknotes are gradually selected from the upper side or the lower side of the stack of banknotes by means of a singler. The selection machine generally has a selection gap with a selection roller on one side and a holding device (generally also a roller) on the other side. The feeding system in the receiving port ensures that the banknotes to be sorted are fed successively to the sorting gap. The pick-out roller grabs by friction fit one of the most protruding banknotes fed in this way. This is usually the bottom or...
