Method and device for processing sheet-like articles
View Patent ↗The present invention relates to a method and apparatus for processing sheet material, in particular bank notes, papers of value and the like. When sheet material is checked for adherence to criteria, at least a group of sheet material fulfilling the criteria and a group of sheet material not fulfilling the criteria are formed. The group of sheet material not fulfilling the criteria is divided into at least two subgroups. This makes it possible to treat the subgroups separately during reworking and pay special attention to the presence of certain problems or errors, e.g. forgeries. This altogether obtains a facilitation of reworking, thereby reducing the effort.
1. A method for processing sheet material, comprising the following method steps:
singling a stack of sheet material,
checking the singled sheet material for adherence to predetermined criteria permitting processing of the sheet material, and forming at least a group of sheet material fulfilling the processing criteria and a group of sheet material not fulfilling the processing criteria and requiring manual reworking for evaluation or checking of the sheet material; and
depositing the sheet material as a function of the result of the checking, wherein, the group of sheet material not fulfilling the criteria is divided into at least two subgroups, a first subgroup containing sheet material that is unrecognizable and/or was recognized as faulty, and a second or further subgroup containing sheet material not fulfilling the processing criteria but recognized during the check;
wherein the subgroups are deposited separately.
2. The method according to claim 1 , wherein the number of sheets allotted to the second or further subgroups is determined.
3. The method according to claim 2 , wherein a total number is determined from the number of sheets in the second or further subgroups together with a number determined for the group of sheet material fulfilling the processing criteria.
4. The method according to claim 1 , wherein features of the sheet material allotted to the second subgroup that uniquely identify the individual pieces of sheet material of the second subgroup are detected and stored.
5. The method according to claim 4 , wherein the detected and stored features are a serial number or data from the check of a particular piece of sheet material.
6. The method according to claim 1 , wherein the sheet material of the first subgroup is resingled and rechecked.
7. The method according to claim 1 , wherein the stack of sheet material to be singled is the result of a prior check and is formed from the group of sheet material not fulfilling the processing criteria in that it consists of first and second subgroups.
8. An apparatus for processing sheet material, comprising
a singling device for singling a stack of sheet material,
a transport system for transporting the singled sheet material,
a checking device disposed along the transport system for checking the singled sheet material for adherence to predetermined criteria permitting processing of sheet material, the checking device dividing sheet material into at least a group of sheet material fulfilling the processing criteria and a group of sheet material not fulfilling the processing criteria and requiring manual reworking for evaluation or checking of the sheet material; and
at least two deposit devices for depositing the groups of sheet material, wherein the checking device is arranged to divide the group of sheet material not fulfilling the processing criteria into at least two different subgroups, two different deposit devices are arranged to receive the at least two different subgroups, and said first deposit device is arranged to receive sheet material that is unrecognizable and/or was recognized as faulty, and said second deposit device is arranged to receive sheet material not fulfilling the processing criteria but recognized during the check by the checking device.
9. Apparatus according to claim 8 , wherein the number of sheets placed in the second deposit device is determined.
10. Apparatus according to claim 9 , including a device for determining the number of sheets placed in further deposit devices, and for determining a total number from said number together with the number of sheets in the second deposit device.
11. Apparatus according to claim 8 , including a detector for detecting features of the sheet material placed in the first deposit device that uniquely identify the individual pieces of sheet material placed in the first deposit device and the checking device is arranged to store said features.
12. Apparatus according to claim 11 , wherein the detected and stored features are a serial number or data of the particular piece of sheet material that are obtained during checking by the checking device.
