Abstract

The states of various sensors and actuators of a bill identifying/counting machine are stored at regular time intervals in a ring memory. If the identifying/counting machine makes an error, among the stored data, the data concerning the error is associated with the error event and the data and the error event are stored together in a nonvolatile memory or a hard disk. Later, the data is extracted and the error is analyzed. Specifically, after the power is turned on or counting is started, digital port input/output information (the states of the sensors and actuators), the analog sensor voltages, and the motor current values are stored at regular time intervals in a memory. If an abnormality occurs, the stored port information and voltages together with the abnormality content are stored in a nonvolatile memory.

Description

Banknote Identification Counter {BILL IDENTIFYING / COUNTING MACHINE}

The present invention relates to a banknote identification counter that accepts banknotes in a hopper, identifies and counts the types of banknotes inserted, and calculates the number of sheets by the total amount or type of banknotes inserted, in particular, the possibility of engaging in the error when an error occurs. The present invention relates to a banknote identification counter that has a function of logging all data in association with an error phenomenon.

Banknote identification that accepts various types of banknotes in a hopper collectively, sends out and sends them back one by one, identifies the types and authenticity, counts them at the same time, calculates and displays the number by the total amount or types of normal banknotes put in The counter is conventionally known (for example, see Japanese Patent Laid-Open No. 2003-296801).

The general structure and operation thereof will be described with reference to FIG. 1 is a longitudinal sectional view showing the internal structure of a general banknote identification counter.

Banknotes mounted on the hopper 1 are sent out, transported by the roller 5 to the conveyance path of the banknote identification counter, and conveyed by a plurality of conveying rollers 6.

It passes through detection sensors 7a and 7b during banknote conveyance, and the kind and authenticity are determined in a banknote identification sensor. Then, it passes through the detection sensor 7c, and is taken in between the blades of the impeller 9 which rotates if it is a normal banknote, and is aligned and integrated with the stacker part 2. On the other hand, in the case where it is determined as the counterfeit bill by the bill identification sensor, the solenoid 10 is operated to move the branch click 11 downward, and the bill is sent to the reject unit 3. The branch position detection sensor 12 detects whether the branch click is actually moving even if the solenoid is "ON". Reference numeral 4 is an operation display unit, which is used to set various settings when performing banknote identification coefficient processing, and to display a count amount of money and the like.

In the banknote identification counter, any of the detection sensors 7a to 7c when the banknote sent out from the hopper unit 1 is jammed, for example, clogged on the conveying path, for some reason. If the output of the sensor becomes abnormal, the banknote identification counter becomes inoperable after that, and the machine stops. In addition, even if a banknote is not actually blocked, the machine may stop by judging it as a jam by abnormality of the detection sensor itself (this is called "fake jam").

In addition, unlike jams, a problem in which the first recognized two sheets are sometimes narrowed at a certain point of time and overlaps with each other may cause a problem of being recognized as one sheet. Such a problem is referred to as a "number mismatch". This is a misjudgement because the number of bills passing through the detection sensors 7a to 7c does not match.

In such a case, there is no problem if the blocked banknote is removed or if the reset button is pressed again to start from the beginning, but in order to prevent recurrence, it is necessary to identify the cause and perform necessary maintenance. In this case, the maintenance is not performed by an operator using a bill counter, but by a professional maintenance checker. However, it is almost impossible to ask the operator in detail about the internal situation of the machine at the time of a problem.

In order to solve such a problem, the cash processing apparatus provided with the status information logging apparatus which records the operation state of each part of a machine in order is proposed (refer Unexamined-Japanese-Patent No. 63-269270). In order to track the blocked portion of the banknote, the apparatus stores the output data as a log in response to a change in the output state of the sensor so that the jam portion can be specified.

However, in the examples of Japanese Patent Laid-Open No. 63-269270, no phenomenon other than jam is disclosed. In reality, however, in addition to the jam, it is necessary to specify later the cause of the error such as the above-described mismatch.

Therefore, an object of the present invention is to provide a banknote identification counter having a logging function so that the cause can be traced to an error phenomenon such as an inconsistency in number of copies, not just a jam.

The present invention relates to a banknote identification counter, and an object of the present invention is a hopper for accepting banknotes to be processed, a delivery transporter for sending and transporting banknotes put into the hopper one by one in the transport path, and the delivery transporter An identification counting unit provided on the downstream side and identifying and counting the types of bills to be conveyed, a stacker provided on the downstream side of the identification counting unit and accumulating the banknotes judged as normal by the identification counting unit; In the banknote identification counter provided with the several various sensor provided in the said conveyance path, and various actuators,

A memory area for storing the output signal information of the various sensors and various actuators generated in the process of conveying the banknotes and counting the banknotes, and the elements involved in a specific error phenomenon among the output signal information are registered in advance. A registration memory area, and when a specific error phenomenon occurs, the registration memory area is searched to specify output signal information related to the error, and data immediately before occurrence of the error phenomenon with respect to the specific output signal information. And a nonvolatile memory loaded from the memory area and stored in association with the error phenomenon.

Further, the above object of the present invention is effectively achieved by configuring the memory area by a ring memory that traverses the memory area.

The present invention stores the state of each sensor or actuator of a banknote identification counter in a ring memory at regular time intervals, and, among the data stored in the event of an error in the machine, an element related to the error is associated with an error phenomenon. The data is stored in a nonvolatile memory or a hard disk, and the data can be retrieved later to analyze the error. Specifically, the digital port input / output information (sensor or actuator status), analog sensor voltage, and motor current values are stored in the memory at predetermined time intervals from the start of the power supply "ON" or counting, and when the abnormality occurs, it is stored until then. The port information and voltage are stored together with the abnormal contents and stored in a nonvolatile memory or the like.

As an example of the said various sensors, banknote detection sensor (hopper part, a conveyance conveyance part, a conveyance path, a reject part, a stacker part), a line sensor LS (for class identification), an authenticity identification sensor (magnetic sensor, an ultraviolet sensor, etc.), Branch position detection sensors; The banknote detection sensor corresponds to the detection sensors 7a, 7b and 7c in FIG. In addition, the line sensor LS and the authenticity identification sensor correspond to the banknote identification sensor 8 of FIG.

Examples of the various actuators include a main motor (shown in FIG. 1), a clutch (not shown), a brake (not shown), a distribution solenoid (corresponding to the solenoid 10 of FIG. 1), and a pin motor (not shown). And the like).

Hereinafter, with reference to the drawings will be described in detail.

2 is a perspective view showing an appearance of a banknote identification counter according to the present invention. Banknotes injected from the hopper portion 1 are identified and counted inside the machine and are aligned and stacked on the stacker portion 2. In addition, banknotes that have become impossible to process due to counterfeit banknotes or contamination or damage are sent to the reject unit 3. The operation display part 4 has various operation buttons, and performs necessary instruction by button operation.

3 shows an example of a block diagram of a circuit for data logging of the present invention. In the figure, 21a to 21c are bill detection sensors and correspond to the detection sensors 7a to 7c in FIG. The banknote detection sensors 21a-21c are comprised by an optical sensor, and are provided in pairs to the left and right across a conveyance path. The drive signals of the banknote detection sensors 21a to 21c are supplied from the CPU 22 through the input / output port, and the output signals of the banknote detection sensors 21a to 21c are transmitted from the input / output port to the ring memory (CPU 22). 23) is stored at regular time intervals. In addition, the output voltage (analog voltage) of the motor, which is a kind of actuator, is converted into digital data by the A / D converter, and stored in the ring memory 23 at predetermined time intervals. In addition, the output signals of the actuators 25 (distribution solenoids, etc.) other than the motor are also stored in the ring memory 23 via the CPU 22 from the input / output port at predetermined time intervals.

Fig. 4 shows an example of the format of data stored in the ring memory 23 at regular time intervals. In digital data, data (upper and lower) at the time of data collection and 11 types of port data (seven types of sensor outputs, A total of 11 types of four actuator outputs) are stored in the ring memory 23 as one set. In the present embodiment, up to 200 sets can be stored, and the 201st sampling data can be overwritten on the sampling data 1. On the other hand, in the case of analog data, the data converted by the A / D converter is stored in the ring memory 23 as a voltage value.

5 is a diagram showing an output signal state of the banknote detection sensors 21a to 21c. FIG. 5A is an example of the case where the processing of the banknote is normally completed, and indicates that the banknote detected by the banknote detecting sensor 21a is also normally detected in the sensors 21b and 21c. On the other hand, in the case of FIG. 5B, since the residence time exceeding the predetermined time t (predetermined to be determined as a jam when this time t is exceeded) in the sensor 21b, the machine is detected. The jam is determined to have occurred and the processing is stopped. However, since it is normally detected in the sensor 21c, it does not generate | occur | produce in the sensor 21b actually, and it turns out in later error analysis that it was a fake jam. This is considered to have occurred because the sensor 21b did not react normally due to contamination or the like.

6 is a diagram illustrating the relationship between an error phenomenon and data to be collected when the error occurs. Such related matters are registered in a registration memory area (not shown).

For example, when a jam occurs, the output information considered to be involved in the jam is the output of the bill detection sensor, the output of the branch solenoid, the branch position detection sensor output, and the motor current value, so that these outputs are connected. Register the port information in association with the jam error code (for example, 05-01).

In the case of a number mismatch, only the output of the bill detection sensor may be involved in this error phenomenon, so only the port information to which the output is connected is an error code of the number mismatch (for example, 03-01). Related to.

In this connection, for example, when a jam is detected as an error phenomenon, the control unit (CPU 22) searches the registration memory area, specifies an output signal related to the jam, and immediately before an error occurs. The associated output signal of the time point is written in the nonvolatile memory 26 together with the error code (code 05-0l of the jam).

FIG. 7 shows the data group and error codes picked up in accordance with the correspondence table of FIG. 6 from among the data described in FIG. 4 stored in the memory area immediately before an error occurs. An example of the data format when writing to the nonvolatile memory or the hard disk 26 is shown.

The data written in the nonvolatile memory or the hard disk in such a format may be transferred to a hard disk or a memory card of a PC connected to a banknote identification counter, and then carried and carried out for error analysis elsewhere.

The error analysis is performed by reading data recorded in the nonvolatile memory or the hard disk 26 and analyzing the data.

First, when the corresponding error phenomenon is "jam", the data of one group to which an error code (05-01) of jam is given in the nonvolatile memory 26 is read, and each port data and motor voltage value are checked. do. As a result, there is no abnormality in the motor voltage value, no abnormality in the branch solenoid output timing (port 11) and the output of the branch position detecting sensor 12 (port 7), and each output (port of the banknote detecting sensor) If abnormality is found only in 1 to port 6), it can be seen that this jam is a fake jam. This is because, if the banknote is actually stuck in the conveying path, the motor is loaded with an abnormal load, and the motor voltage value becomes abnormal.

When the error phenomenon is " number mismatch ", one group of data to which an error code 03-01 of mismatch number is assigned is read from the nonvolatile memory 26, and each port data 1 to data is read. Check port 6. Since only the outputs of the banknote detection sensors are likely to be involved in the error phenomenon, by checking the port data 1 to 6, it is possible to know which sensor has an abnormality. This allows you to specify the sensor to be repaired.

According to the present invention, a banknote identification counter having a logging function can be provided so that the cause can be traced not only to the measurement of the bill but also to an error phenomenon such as a mismatch of the number of sheets.
