Description

[Detailed Description of the Invention] [Summary] A storage box containing paper sheets is rotatably supported,
At the time of feeding, the storage box is rotated (tilted) so that a conveyance belt comes into contact with the paper sheets in the storage box through the window on the bottom plate of the storage box, and the paper sheets are conveyed out by rotation of this conveyance belt. This eliminates the need for a dedicated feeding motor, etc., thereby achieving compactness.

[Industrial Application Field] The present invention is a paper sheet suitable for use in a dummy banknote dispensing mechanism part, etc., which sends dummy banknotes to a conveyance path to check for remaining banknotes when a banknote deposit/disbursement device of a financial institution is in trouble. Regarding the feeding mechanism.

A recycling-type bill depositing and dispensing device has a configuration as shown in FIG. 7, for example. In the figure, reference numeral 1 indicates an input/output port for inserting and dispensing banknotes, and the banknotes deposited here enter the discrimination device 2, where the denomination, authenticity, and front and back are determined.Based on the information on the front and back, ,
Banknotes are sorted into a reversing conveyance path 3 and a non-reversing conveyance path 4. After the front and back sides are aligned, abnormal banknotes enter a pool chamber 5 where they are pooled, and normal banknotes enter a pool chamber 6 where they are pooled. Thereafter, the abnormal banknotes are carried out to the input/output port 1 in order to be returned to the customer. Normal banknotes are sorted into stackers 7, 8, and 9 of 10,000 yen, 1,000 yen, and 5,000 yen bills via the input/output port 1 and the discrimination device 2.
On the contrary, when dispensing money, the bills dispensed from each stacker 7 to 9 are temporarily pooled in the pool room 5 (or 6) via the discriminating device 2, and then taken out to the input/output port 1. In addition, 12 is an attendant's cassette.

In such a bill depositing and dispensing device, if a trouble occurs in the device, it is necessary to check whether there are any bills remaining on the conveyance path within the device.
At this time, it has been conventional practice to send the banknote itself into the conveyance path and check whether there is any remaining paper money, but with this method, the jammed banknotes cannot be fed out due to the low rigidity of the banknotes, resulting in double jams. . Therefore, as shown in FIG. 7, a feeding mechanism 10 for feeding out dummy banknotes with increased rigidity is provided, from which the dummy banknotes are fed out onto a conveying path, and after being conveyed along a predetermined route, they are fed into the collecting section 11, or It is preferable to configure the device so that it is discharged outside the device.

The feeding mechanism 10 that stores the dummy banknotes and sends them out to the conveyance path as necessary is naturally arranged within the banknote depositing and dispensing device. On the other hand, there is a demand for miniaturization of bill depositing and dispensing devices.

[Prior Art] A conventional sheet feeding mechanism is shown in FIGS. 5 and 6. In the figure, reference numeral 15 denotes paper sheets pooled in a storage box 16, which is pushed upward by a lift mechanism (not shown). 17 is a feed roller, 18 is a pick crawler, both rollers 17, 18
are connected by a belt 19, and the feeding roller 2
It is designed so that it can be rotated even when it is 0.
Further, 21 is a separate roller, 22 is an acceleration roller, and the acceleration roller 22 is rotationally driven by a conveyance motor 23. 24 is a passage sensor that detects passage of the paper sheet 15.

The feeding of paper sheets 15 in this conventional mechanism begins with first rotating the feed roller 17 and pick roller 18 with the feeding motor 20, and rotating the separate roller 21 in the opposite direction to the conveying direction. As a result, only one paper sheet 15 is separated and reaches the acceleration roller 22, and the conveyance motor 2
The accelerating roller 22 rotationally driven by 0 is sent out to the conveyance route. The above-mentioned passage sensor 24 is located downstream of the acceleration roller 22, and when the paper sheet 15 is detected here, the feed motor 2
0 is stopped. Then, the paper sheets 15 that were fed out
When the conveyance by the acceleration roller 22 has finished passing there, the feeding motor 20 is started and the next feeding is started.

[Problems to be Solved by the Invention] In the case of the conventional feeding mechanism, in addition to the transport motor 23, a dedicated feeding motor 22 (a fast-response motor such as a pulse motor) is required. Further, it is necessary to provide a one-way clutch in the feed roller 17 and the separate roller 21 portion, and also to provide the pick roller 18 and its pressurizing means, making the mechanism complicated. In addition, when feeding out a long paper sheet 15, even after the leading edge of the paper sheet 15 is detected by the passage sensor 24, the rear end portion of the paper sheet 15 is in contact with the pick roller 18. Therefore, the paper sheet 15 is moved after the detection time while the paper sheet 15 rolls on the pick roller 18 while the feed motor 20 is in a stopped state. Therefore, an excessive load (tensile force) is applied to the paper sheets 15 in this state, which may cause the paper sheets 15 to travel diagonally or wrinkle the paper sheets 15, making it difficult to feed them properly. You may not be able to do it.

The present invention was made in view of these problems, and its purpose is to provide a paper sheet feeder that does not require an expensive feeder motor, is compact, and can stably feed even long sheets. The goal is to provide a mechanism.

[Means for Solving the Problems] FIG. 1 is a diagram showing the basic configuration of the paper sheet feeding mechanism of the present invention, and FIG. 2 is a diagram showing another operating state of the mechanism shown in FIG. 1. In the figure, numeral 31 is a storage box in which paper sheets 32 are stored, and is rotatably supported.
A window 31b is bored near the pivoting end of the bottom plate 31a of the storage box 31, and the paper sheets 32 are exposed.
Note that the upper surface of the paper sheet 32 is pressed downward by a leaf spring 33 installed inside the storage box 31. 34
35 is a conveyor belt disposed opposite to the window 31b of the storage box 31; 35 is a spring that rotates the storage box 31 in the opposite direction (counterclockwise) to the conveyor belt 34;
Reference numeral 36 denotes a drive means that rotates the storage box 31 toward the conveyor belt 34 against the biasing force of the spring 35 when the paper sheet 32 is fed out. This driving means 36
does not have to be something expensive like a motor;
For example, a solenoid etc. will suffice. This driving means 36
During operation, the paper sheets 32 in the storage box 31 come into contact with the conveyor belt 34. 37 is a tension roller which cooperates with the conveyance belt 34 to nip the paper sheet 32, and 41 is a passage sensor. This passing sensor 4
1 is provided in front of the tension roller 37 and outputs a signal that detects the arrival of paper sheets 32 and releases the operation of the drive means 36 to separate the paper sheets 32 in the storage box 31 from the conveyor belt 34. It is something to do.

[Operation] When the paper sheets 32 are not being fed out, the driving means 36 is not operating, and the storage box 31 is in the state shown in FIG. 1 due to the force of the spring 35. Therefore, although the upper surface of the paper sheet 32 is pressed by the leaf spring 33 from above, the lower surface of the paper sheet 32 does not come into contact with the carry-out belt 34 and is not fed out. At the time of feeding, the driving means 36 is operated, and the storage box 31 is rotationally displaced as shown in FIG. As a result, the conveyor belt 34 that entered through the window 31b comes into contact with the sheet 31 at the lowest position, and the sheet 31 is fed out by the rotation of the conveyor belt 34. And paper leaves 32
The paper sheets 3 are conveyed by the tension roller 37 and the conveyor belt 34, and the paper sheets 3 are conveyed by the passage sensor 41.
2 is detected, the actuation of the drive means 36 is released, and the force of the spring 35 moves the storage box 31
rotates and becomes the state shown in Figure 1. If further feeding is required, the drive means 36 is operated again to start the next feeding.

[Example] FIG. 3 is a configuration diagram showing an example of the present invention, and FIG.
The figure is a planar configuration diagram showing only the main parts. In these figures, the same parts as in FIGS. 1 and 2 are given the same reference numerals, and their explanations will be omitted. In the figure, reference numeral 38 denotes a rubber feather made of a rubber material and disposed so that one end thereof protrudes from the feeding opening of the storage box 31. This rubber feather 38 prevents a plurality of sheets 32 from being fed out at the same time. 40 is a stopper for regulating the return position of the storage box 31. The paper sheet 3 is detected by the passage sensor 41.
2 is detected, the drive means 36 is deactivated, and the storage box 31 rotates until it comes into contact with this stopper 40. After the paper sheet 32 passes through this, if there is a need for further feeding, the drive means 36 is operated again to start the next feeding. Here, since one end of the rubber feather 38 protrudes from the feeding opening, the paper sheet 32 pushes aside the rubber feather 38 and comes out of the storage box 31. Therefore, only the lowest paper sheet 32 (one sheet) to which the conveying force is directly applied from the conveyor belt 34 is fed out. In this embodiment, three pulleys 42 are provided as shown in FIG. 4, and a conveyor belt 34 is wound around each pulley 42. However, the rubber feathers 38 are provided only on both sides of the two outer conveyor belts 34. Further, a solenoid is used as the driving means 35, and a pin 36a installed at the tip of the plunger is fitted into a vertical groove at the rotating end of an arm 43 that rotatably supports the storage box 31 ( (locked). The functions and effects of this embodiment are exactly the same as those of FIGS. 1 and 2, and have the following advantages.

Not only does it require an expensive motor for feeding, but it also eliminates the need for a one-way clutch, separate rollers, etc., resulting in a compact configuration.

When feeding out a long paper sheet 32, when the leading edge of the paper sheet 32 is detected by the passage sensor 41,
The actuation of the drive means 36 is released and the spring 3
The storage box 31 rotates due to the force of 5, and the storage box 31
Since the paper sheet 32 and the conveyor belt 34 are separated from each other, the paper sheet 32 after the detection time will not be subjected to excessive load (tensile force) during movement, and the paper sheet 32 will not be skewed. Favorable feeding can be performed without wrinkles occurring on the paper sheets 32.

The stacked paper sheets 32 in the storage box 31 are placed in the window 3.
The leaf spring 33 that presses toward the side 1b also functions to absorb the shock when the storage box 31 rotates and the paper sheets 32 come into contact with the conveyor belt 34, so that the leaf spring 33 that presses the paper sheets and absorbs the shock absorbs the paper sheets 32. becomes extremely simple,
From this point of view as well, the configuration becomes compact.

Furthermore, this embodiment has the advantage that the return position is stabilized due to the provision of the stopper 40, and that feeding is stabilized due to the large number of conveyor belts 34.

[Effects of the Invention] As described above, according to the present invention, not only an expensive motor for feeding out, but also a one-way clutch, a separate roller, etc., are no longer necessary, and the sheet pressing mechanism, etc., is extremely simple, and the overall In addition to having a compact structure, when the leading edge of paper sheets is detected by the passing sensor, the operation of the drive means is canceled and the paper sheets in the storage box and the conveyor belt are separated, so that there is no possibility that the paper sheets are too large. It is possible to realize a paper sheet feeding mechanism that can perform good feeding without being subjected to any load.
