A sorting system for mail items includes sorting registers, a storage module operating on a last-in/first-out principle, a sorting circuit to convey a stream of mail items. The sorting registers and the storage module are connected via switch points to the sorting circuit, wherein the storage module comprises a storage area and an insertion function. An extraction function extracts mail items from the storage area, and a process controller controls the mail item stream and the switch points. The process controller sets, if there is a conveyance fault, part of the switch points so mail items intended for the faulty sorting registers are introduced into the storage area. When the fault is rectified and/or a predefined occupancy level is reached, mail items stored in the storage area are extracted by adjusting a remaining feeding of mail items into the mail item stream, and fed to the sorting registers.

1. A sorting system for flat mail items, comprising: a number of sorting registers;at least one storage module configured to operate on a last-in/first-out principle;a sorting circuit configured to convey a stream of mail items in a stream direction, wherein said sorting registers and said at least
1. A sorting system for flat mail items, comprising: a number of sorting registers;at least one storage module configured to operate on a last-in/first-out principle;a sorting circuit configured to convey a stream of mail items in a stream direction, wherein said sorting registers and said at least one storage module are connected via switch points to said sorting circuit, wherein said at least one storage module has an outlet connected to said sorting circuit downstream of said switch point connections of said sorting registers in said stream direction and said at least one storage module has an inlet connected to said sorting circuit upstream said switch point connections of said sorting registers in said stream direction, andwherein said at least one storage module includes a storage area, an insertion function configured to transfer mail items from the stream of mail items into said storage area and an extraction function configured to extract the mail items from said storage area for a feedback into the mail item stream; anda process controller configured to control the mail item stream and said switch points, wherein said process controller is configured to set, if there is a conveyance fault in a sorting register, at least a part of said switch points so that the mail items intended for the faulty sorting registers are introduced into said storage area of said at least one storage module instead while memorizing a sorting definition of these mail items, andwherein, when the fault is rectified and/or a predefined occupancy level is reached in said storage area, these mail items stored in said storage area instead are extracted by adjusting a remaining feeding of mail items into the mail item stream and fed to said sorting registers corresponding to their initially assigned sorting definition. 2. The sorting system of claim 1, wherein, if the fault lasts longer in a sorting register, the process controller is configured to replace the faulty sorting register at least temporarily by a non-faulty sorting register. 3. The sorting system of claim 1, wherein when the predefined occupancy level is reached a predetermined reserve storage capacity is available, and wherein the process controller is configured to undertake an assignment of the faulty sorting register to a non-faulty sorting register while filling up the reserve storage capacity. 4. The sorting system of claim 3, wherein when the fault is rectified the assignment of the previously faulty sorting register to the non-faulty sorting register is canceled. 5. The sorting system of claim 1, wherein the insertion and extraction functions include a common roller belt unit and a feed stop, wherein the insertion function and the extraction function are selectively operable, in that in the insertion function the mail items in the direction of conveyance of the roller belt unit are transferable from the roller belt unit against the feed stop and thus into the storage area, andin that in the extraction function the last stacked mail item is extractable in the direction of conveyance of the roller belt unit through an extraction opening from the storage area. 6. The sorting system of claim 5, wherein the feed stop is configured to move in a stacking direction to create the extraction opening. 7. The sorting system of claim 5, wherein the storage area includes a separation blade configured to exert, if the insertion function is in place, a first pressure antiparallel to a stack direction on at least one part of the mail items stored in the storage area, and, if the extraction function is in place, a second pressure antiparallel to the stack direction on at least one part of the mail items stored in the storage area. 8. The sorting system of claim 7, wherein the separating blade is configured to be driven by means of an underfloor belt. 9. The sorting system of claim 7, wherein the first pressure is set as a function of at least one characteristic of the mail item currently to be stored, and the second pressure is set as a function of at least one characteristic of the mail item last stored. 10. The sorting system of claim 5, wherein a section of the roller belt unit facing the storage area is shorter than a defined shortest length of a mail item. 11. The sorting system of claim 5, wherein when the extraction function is in operation at least one pivotable support roller for supporting the last mail item stored in the stack is provided, with the at least one support roller being pivoted away from the last mail item stored when the insertion function is in operation. 12. The sorting system of claim 5, wherein one feed direction of the mail items runs in the stream of mail items at an angle to an orientation of the mail items in the storage area. 13. The sorting system of claim 5, wherein the storage area includes an underfloor belt configured to move in the stacking direction of the mail items or antiparallel to the stacking direction of the mail items.
