Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for controlling a paper sheet storage device that stores paper sheets such as banknotes in two storage sections, sorting them according to their types. Regarding.

[Conventional technology]

As a device for sorting paper sheets into two types and storing them in alignment, there is a stacker device described in Japanese Patent Publication No. 57-29751, which has a common entrance and is designed to hold paper sheets. It is equipped with two opposing storage sections partitioned by guides and a selection piece that moves back and forth between these two storage sections, and when storing paper sheets, the selection piece is moved to one of the storage sections in advance. An apparatus is known in which paper sheets are kept on standby and conveyed between two storage sections, and are sorted and stored in the other opposing storage section by moving the selection piece. In this type of device, which side of the two storage sections the paper sheets are stored in is determined by the waiting position of the selection piece when sorting the paper sheets, and before the paper sheets are conveyed. It is necessary to make the selected piece stand by in advance on the other side of the opposing storage section. That is, for example, when sorting to the first storage section, the selection piece is positioned on the second storage section side, and the conveyed paper sheets are pushed and stored in the first storage section by a series of reciprocating movements.

Each storage section is equipped with a detector that detects the full state of paper sheets, and if either storage section is detected to be full, the storage device will prohibit the acceptance of paper sheets from now on. , the operation of the paper sheet processing device is stopped.

[Problem to be solved by the invention]

By the way, when the storage device as described above is used in a vending machine in combination with a bill validator, the number of bills to be inserted into the bill validator and stored in the storage device is determined by the number of bills inserted into the bill validator and stored in the storage device. Since this varies depending on the type of banknote, depending on the price, sales volume, etc. of the product being sold, the time when the storage section becomes full usually differs depending on the type of banknote. At this time, if the banknotes were refused to be accepted as described above, there would be a problem that the sales of the vending machine would decrease.

Therefore, the present invention includes first and second storage sections for storing paper sheets, and first and second fullness detectors that detect whether the first and second storage sections are full, respectively. and a method for controlling a paper sheet storage device, in which a plurality of types of paper sheets to be stored are stored in each storage section according to the type when none of the second fullness detectors detects fullness, 1st
The present invention focuses on the fact that even if one of the second storage sections is full, the other is not full, and an object of the present invention is to provide a control method for a paper sheet storage device that enables effective use of this storage section.

[Means to solve the problem]

In order to achieve the above-mentioned object, when the first fullness detector detects fullness and the second fullness detector does not detect fullness, paper sheets to be stored are stored regardless of their types. It is characterized by being stored in the second storage section.

[Effect]

In the present invention, when the first storage section is full, the paper sheets are stored in the second storage section regardless of the type of paper sheets, so that the paper sheets that should be stored in the first storage section are also stored in the second storage section. It is possible to effectively utilize a storage section that is not full. Moreover, the basic function of storing paper sheets according to their types is maintained until it is detected that the first storage section is full, so there are few problems in use.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings. Figures 1a, b and c are side sectional views and rear sectional views showing the configuration of the paper sheet storage device according to the present invention;
and a top sectional view. In the figure, 1 is the first
A first storage section defined in the upper part of the storage chamber R1 by two guides 11, 11 facing each other at an interval narrower than the width of the paper sheets, and a receiving plate 12 located above these guides 11, 11. , 2 are two guides 21, 2 facing each other at an interval narrower than the width of the second paper sheet.
1 and a receiving plate 23 biased upward by a spring 22, a second storage section is defined at the bottom of the storage chamber R2, and a second storage section 3 is interposed between these two storage sections in the vertical direction. A pushing mechanism unit that can sort and push paper sheets into the first storage section 1 or the second storage section 2 by a push plate 31 that moves reciprocatingly (in a straight line), and the push plate 31 has one end protruding into the storage chamber R1. It is held at the tip of an L-shaped support plate 32. The support plate 32 is loosely penetrated by two parallel slide shafts 33, 33 installed in the machine room R2,
This support plate 3 can be slid vertically.
2, the push plate 31 moves between the first storage section 1 and the second storage section 1.
It moves between the storage section 2 and the storage section 2. On the other hand, a disk 36 is connected to a motor 35 capable of forward and reverse rotation via a reducer 34, and one end is pivotally attached to the circumference of the disk 36, and the other end slides in the vertical direction. A crank mechanism is constituted by a connecting rod 37 connected to a movable support plate 32, and in conjunction with the rotation of a motor 35, the support plate 32 reciprocates (linearly) moves up and down along slide shafts 33, 33. Do this. The stroke has a sufficient distance so that the push plate 31 held at the tip of the support plate 32 can reliably push the paper sheet into the storage section by reciprocating the push plate 31 . 4 is the four guides 11, 11, 21, 2
1 is a passageway formed between a first storage part 1 and a second storage part 2; 4, 52 is a conveyance section that leads to the identification device and the passage section 4;
This is a feed roller that clamps paper sheets onto a conveyance path 51 that communicates with the conveyance path 51 and sends them out to the passage section 4. Also, 61,
Reference numerals 62 indicate a first full detector and a second full detector, which are arranged at the upper and lower parts of the storage chamber R1, and which detect whether the first storage section 1 and the second storage section 2 are full, for example, and which include a limit switch and a storage circuit for its output signal. It is a full detector.

Further, FIG. 2 is a flowchart showing the control operation in the storage device, and the storage operation of paper sheets will be explained below with reference to FIG. In the flowchart of FIG. 2, the storage frequencies of the two types of paper sheets are clearly different, and it is predefined that the paper sheets that are stored more frequently are stored in the first storage section.

In the storage device in the standby state, the pressing mechanism section 3 is stopped at a position where the push plate 31 is placed on the second storage section 2 side as shown in FIG. It is waiting for a selection signal (signal instructing which storage unit to store the paper sheet) corresponding to the type of paper sheet to be output from the identification device (not shown). In step 101, it is checked whether the second storage section 2 is full or not based on the ON/OFF state of the second fullness detector 62, and if it is confirmed that it is full, the process moves to step 104 and an abnormality signal is output. When the identification device outputs a second selection signal instructing to store paper sheets in the second storage section 2, for example, the process proceeds from step 103 to step 1.
05, the pressing mechanism section 3 is driven to move the pressing plate 31 located on the second storage section 2 side upward. A first position detector (not shown) made of, for example, a photoelectric element is disposed in the machine room R2 at a position near the top dead center of the support plate 32, and when the support plate 32 rises to the position, this Detects and outputs a position signal. When this position signal is confirmed in step 106, the process proceeds to step 107, where the pressing mechanism section 3 temporarily stops driving. At this time, the push plate 31
It moves vertically to the first storage section 1 side. After the movement of the push plate 31 is completed, the paper sheets are sent from the identification device to the passage plate 4 via the conveyance path 51. A detector (not shown) made of, for example, a photoelectric element is disposed at the exit of the conveyance path 51.
When it is confirmed that the paper sheet has been reliably fed into the passage section 4 based on the output signal of the detector, the process proceeds from step 108 to step 109, and the pressing mechanism section 3 resumes driving. The push plate 31 moves downward from the first storage section 1 following the support plate 32, and pushes the paper sheets fed into the passage section 4 into the second storage section 2 through the opening formed by the guides 21, 21. A second position detector similar to the above position detector is disposed in the machine room R2 at a position near the bottom dead center of the support plate 32, and when the support plate 32 descends to the position,
It detects this and outputs a position signal. Step 1
When this position signal is confirmed in step 10, the process proceeds to step 111, where the pressing mechanism 3 stops, and the paper sheet storage apparatus returns to the standby state shown in FIG.

In addition, in the standby state, the first storage section 1 is
When the first selection signal instructing to store paper sheets is output, steps 102 to 11 are performed.
Moving on to step 3, first, turn on the first full detector 61.
It is checked whether the first storage section 1 is full or not based on the OFF signal, and when it is confirmed that the first storage section 1 is full, the process jumps to step 105 and goes to the second storage section 2 as described above even though the first selection signal is output. Execute the storage operation of
If it is not full, the process advances to step 114 and the storage operation in the first storage section 1 is carried out. When it is confirmed in step 114 that the paper sheet has been reliably fed into the passage section 4, the process proceeds to step 115, where the pressing mechanism section 3 is driven and the pressing plate 31 is moved upward. The push plate 31 places the paper sheets sent into the passage section 4 on its upper surface, pushes the paper sheets up into the first storage section 1 through the opening formed by the guides 11, 11, and then pushes the paper sheets into the first storage section 1. 32, the first
The user moves from the storage section 1 to the second storage section 2 again. Then, when the support plate 32 descends to the position of the position detector located near the bottom dead center, a position signal is output from the detector, the process proceeds from step 117 to step 118, and the drive of the pressing mechanism section 3 is stopped. Then, the paper sheet storage device returns to the standby state.

Next, a storage operation will be described in which the identification device distinguishes the authenticity of one type of paper sheet and conveys only the paper sheet determined to be "true" to the storage device. At this time, the identification device is specified to output a first selection signal (genuine bill signal) when determining that the paper sheet is "genuine".

When a genuine bill signal, that is, a first selection signal is received from the identification device in the standby state, the process moves from step 102 to step 113, and checks whether the first storage section 1 is full based on the output of the first fullness detector 61. If it is not full, the process proceeds to step 114 and the storage operation in the first storage section 1 is started. The details of the storage operation have been described above, so they are omitted here.

In this way, the paper sheet storage device sequentially distributes and stores the paper sheets conveyed from the identification device into the first storage section 1 when the first storage section 1 is not full. Then, when the first storage section 1 becomes full, the first storage section 1 becomes full.
Since the full detector 61 is in the ON state, upon receiving a genuine bill signal from the identification device, the process moves from step 102 to step 113 to step 105, and the storing operation in the second storage section 2 is started. Therefore, after the first storage section 1 is full, all paper sheets conveyed from the identification device are sorted and stored in the second storage section 2 side. The storage operation has been described above, so it will be discussed here.

Then, when the second storage section 2 is also full, the second fullness detector 62 is turned on and the process proceeds to step 101.
Then, the process moves to step 10, and an abnormality signal is output to the identification device. In response to this signal, the identification device prohibits the acceptance of paper sheets, displays an indication that the paper sheet is unusable on a display, etc., and notifies the user of this fact.

In addition, when the first storage section 1 becomes full while paper sheets are sorted and stored in two storage sections based on the selection signal output from the identification device, the paper sheets that should be stored in the first storage section 1 are The type is sorted to the second storage section 2 regardless of its type, and the second storage section 2
Various types of paper sheets will be stored. However, since this condition is temporary and the amount of overlap between the two types of paper sheets is small, it is less risky than stopping the paper processing equipment. small.

FIG. 3 is another flowchart showing the control operation in the present invention, and represents the execution of the storage operation in the second storage section shown in steps 114 to 119, and "" also indicates the execution of the storage operation in the second storage section.
This represents the execution of storage operations in the second storage section indicated by 112.

When neither of the two storage sections is full, the storage device cycles through steps 201 to 204 and waits for a selection signal to be output from the identification device. When, for example, the first selection signal is output from the identification device, the process moves from step 203 to ``'', where the storage operation in the first storage section 1 is started, and the second selection signal is outputted from the identification device.
When the selection signal is output, the process moves from step 204 to [ ] to start the storing operation in the second storage section 2, and each paper sheet is stored in a predetermined storage section.

For example, when the second storage section 2 of the two storage sections is full, steps 201, 202, 205,
206 and waits for a selection signal to be output from the identification device. In this case, regardless of whether the first or second selection signal is output, ""
Then, the storage operation into the first storage section 1 is executed.

For example, when the first storage section 1 of the two storage sections is full, steps 201, 207, 208,
209 and waits for a selection signal to be output from the identification device. In this case, regardless of whether the first or second selection signal is output, ""
Then, the storage operation into the second storage section 2 is executed.

Further, when both storage sections are full, steps 201 and 207 to step 210 are performed.
Then, it outputs an abnormal signal to the identification device and prohibits the acceptance of paper sheets.

In the paper sheet storage device controlled according to the flowchart shown in FIG. 3, if one type of paper sheets is to be stored one after another, storage may be started from any storage section, and the storage can be started from any storage section. This is even more convenient because the order of distribution to the storage units (first allocation to the first storage unit) is not limited as in a storage device that operates according to a flowchart.

〔Effect of the invention〕

As explained above, according to the present invention, in a paper sheet storage device that stores paper sheets by sorting them into two storage sections according to their types, when one storage section is full, the paper sheets are stored in that storage section. Since the paper sheets of the desired type are stored in the paper sheet storage section, the two storage sections can be effectively used even when storing a large number of one type of paper sheet. can do. Therefore, after one storage section becomes full, it is possible to continue accepting paper sheets without providing a special storage section just for storing the paper sheets that should be stored in this storage section. I can,
To improve the operating rate of a vending machine, etc., which has a paper sheet storage device to which the present invention is applied, compared to conventional ones, without increasing the size of the device by having only two storage sections for each denomination, as in the conventional one. be able to.
