JPH031292A - Containing control method for paper money discriminating device - Google Patents

Abstract

PURPOSE:To shorten time interval for discriminating paper money by constituting a device so that a discriminating means and a containing means can be operated by keeping pace with each other. CONSTITUTION:When a containing command is received from a main control part 02 after a papermoney is reserved temporarily, a control part 01 returns to a state of waiting for throw-in the next paper money as long as there is a receiving permission of the next paper money by the main control part 02 by only starting an extruding mechanism 5 after carrying a paper money to a containing stop position in a main routine (without waiting until the extruding mechanism 5 returns to the holding position). Also, since a stop of the extruding mechanism 5 is executed by an interruption routine repeated at every 2.5mS, a discriminating operation and a containing operation of the paper money can be executed by keeping pace with each other substantially. In such a way, the time until the next paper money is discriminated after the paper money is discriminated once can be shortened.

The present invention relates to a control method for storing banknotes in a banknote recognition device that has functions such as identifying inserted banknotes and storing genuine banknotes in a storage, and particularly relates to a banknote storage control method that can reduce the waiting time for banknote insertion as much as possible. The present invention relates to a storage control method for an identification device. Note that in the following figures, the same reference numerals indicate the same or equivalent parts.

[Conventional technology]

FIG. 1 is a block diagram showing the configuration of a control circuit as an embodiment of the present invention, and this diagram will be used hereinafter.
The conventional technology will be explained using FIGS. 3 and 4. Note that, in the prior art, the extrusion mechanism/parallel control means 03 shown in FIG. 1 is not provided. Furthermore, FIG. 3 is a flowchart for explaining the conventional operation of FIG. 1, and FIG. 4 is an explanation of the main different states in the banknote identification device until a banknote determined to be a genuine banknote is stored in the storage. It is a diagram. That is, Figure 4 (A) shows the state in which the genuine bill is temporarily held, Figure 4 (B) shows the state in which the genuine bill has reached the storage stop position, and Figure 4 (C) shows the state in which the genuine bill is pushed into storage 1. are shown respectively. Now, in FIGS. 4(A) to 4(C), reference numeral 8 (8A. 88) is a conveying mechanism for conveying the inserted banknotes, which is composed of a belt conveyor or the like. 9 (9A, 9B) is a transport motor,
The transport motor 9A drives the transport mechanism 8A, and the transport motor 9A drives the transport mechanism 8A.
B drives the transport mechanism 8B. 1 is a banknote identification unit provided on the conveyance path of the conveyance mechanism 8A;
Further, 4 (4A, 4B) is a banknote storage provided on the transport path of the transport mechanism 8B, and in this example, 4A is a storage for 1,000 yen bills, and 4B is a storage for 5,000 yen bills. . 5 (5
A and 5B) are push-out mechanisms provided corresponding to the storages 4A and 4B, respectively, and have the role of pushing banknotes conveyed to the front of the mechanisms into the corresponding storages. In FIG. 4, the conveyance mechanism 8A conveys the banknotes inputted from the left end side to the right and passes the recognition unit 1. If the banknotes are determined to be genuine here, the banknotes (genuine banknotes) are ) 3 is further conveyed to the mechanism 8B side together with the conveyance mechanism 8B, and brought into a -time hold state as shown in (8) of the same figure. Reference numeral 2 designates a withdrawal prevention mechanism provided between the two transport mechanisms 88 and 813, which has the role of preventing genuine bills 3 on hold from being pulled out toward the slot (to the left). However, if it is necessary to return the genuine bill 3 that has been temporarily held in this manner, the pull-out prevention mechanism 2 is pulled downward via a solenoid (not shown), and at the same time, the transfer mechanism 8A, 8
Rotate B in the opposite direction and return genuine bill 3 to the slot side. Next, when a banknote storage command is issued from the main control unit, which will be described later, the delivery mechanism 8B transfers the genuine banknotes 3 that have been held for a while as shown in FIG. It is transported to a predetermined position (referred to as a storage stop position) on the front surface of the storage 4A or 4B corresponding to the storage area 4A or 4B. The genuine bill 3 shown in FIG. 4(B) is further pushed into the storage 4B by the pushing operation of the pushing mechanism 5B upward in the drawing as shown in FIG. 4(C). However, the extrusion mechanism 5B then returns to the standby position shown in FIG. 4 (8) or (B), thereby completing the storage (pushing) operation of the extrusion mechanism 5B. Next, in FIG. 1, reference numeral 01 denotes a control unit that controls the entire bill validating device, and is composed of a microcomputer and the like. 02 is a main control unit that controls a vending machine, etc., and the control unit 01
After receiving information such as the denomination, etc. from the banknote and selling the product, the banknote is returned to the control unit O1. Give instructions for storage, etc. Reference numeral 6 denotes a hole position sensor, which is provided at a predetermined position of the seed on the banknote conveyance path, and detects the conveyance position of the banknote, etc. 7 (7A, 7B) are storage position detection switches that are opened and closed in conjunction with the extrusion mechanisms 5A and 5B, respectively;
, 5B push the genuine bill 3 into the storage 4 as shown in FIG. 4(C), and then move it to the standby position (as shown in FIG.
In other words, this switch is turned on only when the banknote storage is returned to the position where it is determined that banknote storage is complete. Next, the conventional operation of the control section 01 shown in FIG. 1 will be explained using FIG. 3 while referring to FIG. 4. In addition, the following 101-12
Reference numeral 4 indicates a step in FIG. Also, Figure 3 (^) shows the main routine, and Figure 3 (B) shows the 2.5

As a result of this identification, if the banknote is determined to be a genuine banknote (103, branch Y), the denomination information is sent to the main control unit 02, and the banknote is put on hold as shown in FIG. 4 (8). It waits for a command to collect or refund money from the control unit 02 (104, branch N→104...). Next, when a collection command is received from the main control unit 02 (104, branch Y→105, branch Y), the banknote is conveyed to the corresponding storage stop position via the conveyance motor 9B and the conveyance mechanism 8B (106 ). In this way, when it is detected via the hole position sensor 6 that the banknote has reached the correct storage stop position (in this example, the front of the storage compartment 4B) as shown in FIG. 4(B) (107

).

[Problem to be solved by the invention]

However, in the conventional banknote identification device that operates as described above, when the operation of accepting and storing banknotes is repeated continuously, the banknote 3 held at - time is first conveyed to the storage stop position at the front of the storage 4. Since the next inserted banknote is identified after being stored in the storage 4 by the extrusion mechanism 5, there is a problem in that it takes time to identify the next banknote after one banknote is identified. Further, in order to solve this problem, methods such as increasing the conveying speed, shortening the conveying distance, or increasing the number of control units in the banknote recognition device can be considered, but there is a problem that the cost increases. Therefore, the present invention provides a storage control method for a banknote identification device that can perform the operation of storing banknotes determined to be genuine in a storage box and the operation of identifying the next inserted banknote in parallel. The objective is to solve the above problem.

[Means to solve the problem]

In order to solve the above-mentioned problems, the method of the present invention includes an identification means (identification unit 1, conveyance mechanism 88, etc.) for identifying the inserted banknote, and a method for identifying a genuine bill (such as 3) by the identification means. In a banknote identification device comprising a storage means (conveying mechanism 8B, extrusion mechanism 5, etc.) for storing banknotes stored in a storage (4, etc.), the identification means (via extrusion mechanism/parallel control means 03, etc.) 1 so that the storage means can operate in parallel.

[For use]

In the present invention, when a storage command is received from the main control unit 02 after temporarily storing banknotes, the control unit 01 simply transports the banknotes to the storage stop position in the main routine and then starts the extrusion mechanism 5 (the extrusion mechanism 5 (returns to the standby position), and returns to the state of waiting for the next banknote to be inserted as long as there is permission from the main control unit 02 to accept the next banknote. Since the extrusion mechanism 5 is stopped by an interrupt routine that is repeated every 2.5 mS, it is possible to substantially perform the banknote identification operation and the storage operation in parallel.

【Example】

Next, the present invention will be explained in detail based on FIGS. 1 and 2. In the present invention, as described above, the extrusion mechanism/parallel control means 03 is included in the control section 01 in FIG.
is provided. Further, FIG. 2 is a flowchart for explaining the operation of FIG. 1 and corresponds to FIG. 3. Note that the following reference numbers 101 to 124 and 201 to 225 indicate the steps in FIG. 2, and among these, each step 101 to 124 corresponds to the step with the same reference number in FIG. 3. That is, in FIG. 2, compared to FIG. 3, steps 201 and 202 are newly added in the main routine of FIG. 2(A), and step 221 is newly added in the interrupt routine of FIG. 2(B).
~225 have been newly established. To explain FIG. 2(A), the control unit 01 identifies the inserted banknote as a genuine banknote, temporarily holds this banknote, and then the main control unit 01
When a collection command is received from 2 (101 to 105° branch Y
), after conveying this banknote to the storage stop position, the extrusion mechanism 5 is started (106→1071 branch Y→201). Then, unless there is permission to accept the next banknote received from the main control unit 02 and the storage NG flag described later is set, the state returns to the state of waiting for the next banknote to be inserted (11 branch Y → 2021
Branch N → 101). In addition, in the interrupt routine of FIG. 2 (Il1), the same processing operations (1
21 to 124), the following processing operations are performed. That is, in step 201, a flag indicating that the extrusion mechanism 4 should be started (
(not shown) is set up (221, branch Y), and the storage position detection switch 7, which has been turned F, turns ON again.
When this is detected (222, branch Y), the push-out mechanism assumes that the push-out mechanism 5 has returned to the standby position after pushing the bill into the storage 4 (that is, the bill has been normally stored). 5 is stopped (223). On the other hand, if the storage position detection switch 7 is not turned ON in step 222 (branch Y) and the time has not exceeded (that is, the elapsed time since the detection switch 7 was turned OFF has not exceeded the predetermined time) ( 224, branch N
), the extrusion mechanism 5 is left in operation. However, if the time has expired in step 224 (branch Y),
Assuming that a failure such as bill jamming has occurred, a storage NG flag is set, and the extrusion mechanism 5 is stopped (225). Note that steps 201 to 225 in FIG. 2 correspond to the functions of the extrusion mechanism/parallel control means 03 in FIG. 1.

【Effect of the invention】

According to the present invention, it is possible to store a banknote determined to be a genuine banknote and to identify the next banknote in parallel, thereby reducing the time interval between banknote recognition during continuous operation of the banknote recognition device at low cost. This has the effect of reducing customer frustration.
