Test and control circuit for a document sorting machine

In the machine processing of receipts in postal checks or banking, in particular when processing checks, transfers and the like, the need often arises to sort the receipts, for example, according to their account numbers or according to their invoice amount. With such documents, all the data required for machine processing is often printed in a special line at the bottom edge of the document in machine-readable font, whereby this line is divided into several meaningful fields separated by special characters Position of a grief, for example the Eonton number, can be sorted decadically · That is, documents with the number 1 at the relevant sorting point of the sorting field are placed in a sorting compartment Wr. 1, receipts with the number 6 go to a Fmem Sr «6 * IJm ζ.Β», data of the receipts in the storage system © läse »kontenfüta * emdem Bechners - a & mfig ilagisetbänäer is used for this - with a short access time asm relevant harvest & © atö © imlesem on Mm & ma ^ are the documents

Sorting machines are already known, soft devices that check whether a document sequence is monotonous. Such a test can, for example, proceed in such a way that During the decadic sorting at a point η of a Hummer of a document, it is checked whether it is at the point n-1 of the same Document that is known to have already been sorted, this document - in ascending order - has a number b, which is greater than or equal to number..a of the previous document. If this test turns out negative, then lies a monotony error. Such a monotony error can arise when the operator removes the Stack formed from the individual sorting compartments during the previous sorting process, this stack is not in the correct one Has merged the order (multiple errors). A monotony error can also arise from the fact that a document was read incorrectly at the previous sorting point, or that a double print was made during the previous sorting process, So two documents at once, delivered into the conveying channel leading to the reading head and one of the documents was not read, or that finally, due to some mechanical failure, a document was dumped into the wrong sorting compartment (more sporadically Failure).

In len known machines it is now the case that the whole machine is shut down when a monotonous error occurs. This _r && t means that the machine is not only created in the case of monotonicity errors, wl * they are created by the false collapsing of stacks, " do away;

(sporadic errors) is shut down. But that becomes hers effective performance is significantly reduced.

The invention aims to remedy this disadvantage by for it ensures that the sorting process is only interrupted if there is no sporadic monotonous error.

For this purpose, the invention provides a test and control circuit cooperating with a device for monotony testing for a document sorting machine with the characteristic that it contains a countable circuit that with the monotony checking device is connected via message lines and can assume at least two switching states in succession, and that this circuit via control lines with the device for controlling the actuation device for the sorting compartment switches and is connected to the control for the document feeder, such that in the first state of the circuit on this causing document is directed into a special compartment and in the second state the document feed is switched off and all documents that are still in the conveying path of the sorting machine are transferred to a special compartment.

It is preferably provided that the countable circuit is connected to the monotony testing device via two lines which carry the signals "monotony not disturbed" and ^w monotony disturbed ", and that it can assume a total of three switching states in succession (" monotony not disturbed "," Monotony sporadically disturbed "," Monotony constantly disturbed ") and output?

If it is now found in the evaluation circuit A- that a document disturbs the monotony, a signal (1) is emitted from there on the line 6.

At the same time will the document feed is switched off by the controller 15, and to the display device 16 a signal is given "monotony disturbed"; the machine is stopped

The device according to the invention thus ensures that, in the event of sporadic monotony errors, the relevant document is directed to the reject area or another special compartment without the machine interrupting its sorting process the machine is shut down in order to eliminate the error before further sorting.
