Definitions

  • the invention relates to an automated teller machine with an output point at which banknotes are issued in accordance with a predetermined amount of money, at least one storage location for storing the banknotes, a withdrawal device provided at the storage location, which in each case removes a banknote from the storage location, and a control unit controlling the withdrawal device , which determines the required number of withdrawal steps in accordance with the predetermined amount of money, a transport device which connects the storage location to the issuing point, and a test device arranged between the storage location and the issuing point along the transport path for detecting an inadvertent withdrawal of several banknotes in one withdrawal step .
  • a cash dispenser of the type mentioned above is used, for example, by banks and credit institutions to pay out amounts of money to customers.
  • a dispensing point for example a flap or a dispensing slot, is provided on the automated teller machine from which bank notes are issued to the customer.
  • the customer has the option of using a control panel such as a keyboard or a touch screen to enter the desired amount of money to be dispensed by the cash dispenser.
  • At least one storage location for storing the banknotes is provided within the automated teller machine.
  • An interchangeable storage cassette for example, is used as the storage location and is inserted into a holder.
  • a withdrawal device which is controlled by a control unit and is intended to remove only one bank note from the storage location in a withdrawal step.
  • the bank account taken from the storage location note is then conveyed to the issuing point via a transport device, for example a conveyor belt or several pairs of rollers.
  • a transport device for example a conveyor belt or several pairs of rollers.
  • the problem with this known automated teller machine is that, with decreasing banknote quality, the withdrawal device removes several banknotes from the storage location in a withdrawal step. As a result, the dispensing process must be interrupted and carried out again, and the banknotes already stored in the buffer store must be conveyed into the reject container. Since the storage locations in automated teller machines can also contain only a limited amount of banknotes for security reasons, the storage locations are quickly empty in the event of frequent withdrawals, so that the automated teller machine is no longer ready for operation.
  • the invention has for its object to develop a cash dispenser of the type mentioned so that it has high availability even with frequent deductions.
  • the checking device detects the number of banknotes which have been withdrawn too much in one withdrawal step and that the control unit reduces the remaining number of subsequent withdrawal steps in accordance with the number of excess banknotes withdrawn by the checking device.
  • the number of banknotes which are withdrawn too much in one withdrawal step is recorded and offset against the remaining amount of the total amount of money by the control unit reducing the remaining number of the following withdrawal steps.
  • the remaining amount to be paid out is reduced in accordance with the excess amount of money paid out, without the payment process having to be interrupted and carried out again.
  • the cash dispenser has a consistently high level of availability, even in the case of frequent multiple withdrawals.
  • a reject container is additionally provided, which holds the banknotes of the last withdrawal step if the test device cannot properly record the number of banknotes of the last withdrawal step.
  • the last deduction step is repeated by the trigger device. In this way it is ensured that the bank customer is neither paid out an amount of money that is too low nor higher than desired.
  • the withdrawal steps are first carried out in the closest possible chronological sequence. Then the at least one withdrawal device is stopped before a predefinable withdrawal step is carried out until all withdrawn banknotes have passed through the checking device (36). Only then are the deduction steps still required to be carried out.
  • Several banknotes can be located on the transport route from one of the storage locations to the test device without it being known whether and how many multiple prints are underneath. However, if the number of deduction steps still to be carried out is only determined when the check for multiple withdrawals has been carried out, the number of banknote transports from the intermediate storage to the reject container can be reduced even further.
  • the number of deduction steps before the last required deduction step is advantageously specified as a function of the statistical frequency of the multiple deductions, with multiple deduction statistics being kept in the control unit or permanently stored therein as a table.
  • the result of this is that on the one hand the probability of too much banknotes collected in the buffer is minimal, on the other hand the time for processing a customer order is kept as short as possible.
  • a mechanical measuring device with a probe is proposed, which is based on the Measuring device passes banknotes under pre-tension and its proportional displacement indicates the thickness of the banknotes passed.
  • Suitable as a measuring probe is, for example, a firmly clamped leaf spring with a strain gauge attached to it, or a pivoting rocker arm, the displacement of which is detected, for example, by an induction sensor.

  • This weakening of the light intensity is detected by the light-sensitive sensor 60 and passed on to the control unit 50.
  • the control unit 50 compares the measured light intensity with a predetermined light intensity range for banknotes with a certain thickness. If the measured light intensity lies within this range, this means that the test device 36 has detected a single bank note 70.
  • the probe 58 Seen in the transport direction after the light source 56, the probe 58 is arranged, which is pivoted by the bank note 70 passed in the direction of the upper housing part 52.
  • a motion sensor (not shown) detects the swiveling movement of the probe 58 and generates a signal indicating the thickness of the bank note 70 being passed, which signal is forwarded to the control unit 50, which compares the signal with a predetermined range of thickness values. If the signal lies within the specified range of thickness values, this means that only a single bank note 70 has been passed.

This information is forwarded to the control unit 50, which calculates the required number of withdrawal steps for each withdrawal device 26 from the predetermined amount of money. Each withdrawal device 26 then removes banknotes 24 from the storage cassette 24 assigned to it in accordance with the calculated withdrawal steps. The banknotes are fed via the transport device 28 and the conveyor device 42 to the stacking wheel 44 until the desired amount of money is reached.

The series is particularly long when removing banknotes from the bottom storage cassette 24.
  • the sequence of deductions is therefore discontinuous, ie the banknotes are first withdrawn in the closest possible chronological order. Depending on the number of statistically expected multiple deductions - such statistics are kept in the control unit 50, for example, but can be permanently stored there as a table of values - the sequence of deduction processes is stopped before the last, penultimate or an earlier deduction process until all withdrawn banknotes pass through the checking device 36 have run.

Abstract

L'invention concerne un distributeur automtique d'argent (10) comportant un emplacement de distribution (18), au moins un emplacement de stockage (24), au niveau duquel est prévu un dispositif de prélèvement (26), ainsi qu'un système de transport reliant l'emplacement de stockage (24) avec l'emplacement de distribution (18). Ce distributeur automatique d'argent (10) comprend également une unité de commande déterminant le nombre nécessaire d'étapes de prélèvement en fonction d'une somme d'argent prédéfinie, ainsi qu'un système de contrôle (36) permettant de détecter le nombre des billets de banque prélevés lors d'une étape de prélèvement. Si trop de billets de banque sont prélevés par le dispositif de prélèvement (26) de l'emplacement de stockage (24) lors d'une étape de prélèvement, le système de contrôle (36) détecte le nombre des billets de banque prélevés en surplus et l'unité de commande (50) réduit en conséquence le nombre des autres étapes de prélèvement.
