Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a coin dispensing device for separating and discharging a large number of coins that are not stacked and aligned one by one.

(Prior Art) As a conventional coin processing machine, for example, in a coin side machine, a coin wrapping machine, etc., ff1Ji5 placed in a coin storage section is used.
A rotating disk is used as a device for feeding a large number of unaligned coins one by one to a sorting passage. This uses centrifugal force to pick up coins on the surrounding wall due to the rotation of a rotating disk.
Coins are sent out one by one from a delivery section cut out in a part of the peripheral wall to the sorting passage.

Recently, coin depositing machines and circulating coin depositing and dispensing machines have been developed. The machine also uses a rotating disk as a device to send out coins.

(Problems to be Solved by the Invention) Processing machines as described above are usually available for tellers, which are handled by the teller inside the bank counter, and for ATMs, which can be operated by the customer himself at the automatic machine corner of the bank. There is a demand for miniaturization and N-shape for both machines (the machine is integrated with a banknote deposit/dispensing machine), but as long as a rotating disk is used, there is a limit to miniaturization and thinning.

Therefore, separating rollers are provided oppositely on the conveying surface of the conveying belt with an interval that allows one coin to pass through, so that when the conveying belt rotates forward in the coin conveying direction, the opposing circumferential surface rotates in the opposite direction. We considered a coin feeding device that separates coins that are conveyed in an overlapping state into one coin by rotating the separating roller in the opposite direction.In particular, by rotating the conveying belt and the separating roller in conjunction with one motor, it is possible to separate coins into small coins. Consideration has been given to making it smaller and thinner.

With its hard L1 delivery device, the primary purpose is miniaturization and bookkeeping 8! However, coins may become jammed between the conveyor belt and the separation roller, and it becomes necessary to remove the jammed coins. Therefore, an attempt was made to remove the jammed coins by reversing the conveyor belt by reversing the motor, but since the reverse rotation of the motor caused the minute 1io-ra to rotate forward, the reverse rotation of the conveyor belt caused the jammed coins to be removed. This may prevent the clearing action or cause another coin to be caught between the separating roller and the conveyor belt, thereby hindering removal of the jammed coin.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a coin feeding device that can easily and reliably eliminate coin jams that occur between the conveyor belt and the separation roller. be.

(Structure of the Invention) (Means for Solving the Problems) In the present invention, separation rows 521 are provided oppositely to each other by forming an I!ll interval on the conveying surface of the conveying belt 24 through which one coin can pass. A coin feeding device that rotates a separation roller 27 in a reverse direction so that the opposite surface rotates in the opposite direction to the normal U rotation of the conveyor belt 24 in the coin conveying direction, and separates coins C conveyed in an overlapped state into one piece. , one motor M for interlockingly rotating the conveyor belt 24 and the minute 11 + cola 27;
In the power transmission system from the motor M2 to the separation row 527, there is provided a one-way clutch 27a that does not transmit power from the motor M2 to the separation row 527 when the conveyor belt 24 rotates in reverse due to the reverse rotation of the motor M2. It is an intervention.

(Function) The present invention separates and sends out the coins C one by one by normal rotation of the conveyor belt 24 and reverse rotation of the separation roller 21. On the other hand, when a coin jams, only the conveyor belt 24 is reversely rotated by the reverse rotation of the motor M2. , the separation row 527 is prevented from rotating through the intervention of the one-way clutch 27a, thereby eliminating the coin jam.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

A coin dispensing device is shown in FIGS. 1 and 2, and this coin dispensing device has a machine frame 1, and the machine frame 1 has an opening on the top surface and a hard disk. A receiving section 2 for receiving coins C is provided, and a processing section 3 for processing coins C is provided inside. The length of the other coin (in the horizontal direction in Figure 1) is long, and the length of the other coin in the width direction (in the front and back direction of the paper in Figure 1) is larger than the diameter of the denomination that can be processed. The diameter is approximately the maximum diameter of the denominations that can be processed.

A first holding section 5 is provided in the receiving section 2 of the machine frame 1,
The first holding section 5 has a bottom surface made up of a first conveyor belt 6, and a side surface facing in the coin processing direction made up of a side plate 7 and a regulating member 8. Then, the first conveyor belt 6 is connected to the drive pulley 11 and the driven pulley 12 with i! The rack is rotated along the cargo processing direction, and is driven in forward rotation in the clockwise direction in FIG. The hard rAC received on the belt 6 is led out in the direction of the regulating member 8 and released from the end of the belt.

Further, the regulating member 8 is rotatably mounted around a support shaft 15 at the upper end, and is rotatable in the counterclockwise direction 81 in FIG. The lower end 18b (lower end) is rotated at a vertical position facing the upper surface of the first conveyor belt 6, and is constantly biased clockwise by a tension spring 16 connected to the rear end 18b (upper end). And this rule! When the coin C is sent out in the direction of the standard Il1 member 8 by the forward rotation of the first conveyor belt 6, the IJ member 8 is configured such that even if a plurality of hard 15C coins are sent in an overlapping manner, the tip portion 8a carries out the passage υ1. This prevents the number of coins C from being ejected from the end of the first conveyor belt 6 all at once.

Further, a detection plate 18 having a detection piece 17 bent at its tip is protruded from the upper part of the regulation member 8, and when the regulation member 8 is in a vertical state, the detection plate 18
Intervene in between to block light. This photosensor PS1 is turned on when the detection piece 17 is interposed in the light-blocking state, and turned off when the detection piece 17 is moved and the light is transmitted. Many meters hard in the direction! When the IC is sent and the regulating member 8 is rotated counterclockwise against the tension spring 16, the detection piece 17 is also rotated together, and the photo sensor PS1 is rotated. By turning off, the first conveyor belt 6
is driven in reverse rotation to prevent the coin C from getting stuck between the first conveyor belt 6 and the regulating member 8.

Further, in the machine frame 1 in the coin width direction facing the upper surface of the first conveyor belt 6, a photosensor PS2 is disposed at a position where the hard aC received from the receiving section 2 falls, and this photosensor PS2 is turned off in a transparent state, and turns on when the coin C falls onto this first conveyor belt 6 and blocks light, and this turns on the second conveyor belt 2, which will be described later.
4 is driven.

The coins C discharged from the first conveyor belt 6 pass through an introduction chute 21 whose width becomes narrower along the lower side and a side plate 22.
It is accepted into the second holding section 23 via. The second holding section 23 has a width direction slightly wider than the diameter of the maximum diameter coin of the denomination to be processed, and has a bottom surface formed by a second conveyor belt 24. This second conveyor belt 24 is rotated by a drive pulley 25 and a driven pulley 26 along the coin processing direction below the first conveyor belt 6, and this second conveyor belt 24 is rotated in forward and reverse directions. The coin C discharged onto the second conveyor belt 24 by forward rotation is sent out to the left in FIG. 1.

Further, a separation roller 27 is provided above the end of the second conveyance belt 24 in the sending direction at a predetermined interval from the upper surface of the second conveyance belt 24, and this separation 0-527 The outer circumferential surface of the upper surface of the second
Of the two or more coins C that are sent in an overlapped manner by the conveyor belt 24 of The hardness v1c is 1 from the end of the conveyor belt 24.
Release one by one. In addition, a guide plate 28 is provided at an upper position facing the outer circumferential surface of the 1110-ra 27, and this guide plate 28 allows the separation 0-527 to rise upward and jump over the separation roller 27 as the separation 0-527 rotates. Coin C trying to do so
is returned to the second holding section 23.

Coins C released from the end of the second conveyor belt 24
are received by the receiving plate 31, and the received coins C are delivered onto a delivery belt 33 by a discharge roller 32 that protrudes from the receiving surface of the receiving plate 31.

This lead-out belt 33 transports the led-out Ta coins C, for example, to 1a of a coin processing machine to which this coin feeding device is installed.
The cargo is conveyed onto a discrimination path where the cargo is discriminated.

Further, the separation roller 27 and the discharge row 532 are driven by a motor M2 that drives the second conveyor belt 24, and one-way clutches 27a and 32a are used, respectively.
Since the motor M2 is connected through the motor M2, it does not rotate when the motor M2 rotates in reverse.

Further, a photosensor PSa and a photosensor PS4 are arranged at the upper and lower parts of the second holding section 23 facing the copper plate 22, a photosensor PS5 is arranged facing the upper surface of the second conveyor belt 24, and further, Said second conveyor belt 2
A photosensor PSB is arranged between the surface of 4 and the outer periphery of the discharge row 532, and each of these 7 photosensors P33 to PS
6 is turned off when the coin C is not introduced and is turned on when the light is blocked by the coin 11C.

Next, control 7! The configuration of the JS 40 will be explained based on the control block diagram shown in FIG.

The control unit 40 includes a central control unit (hereinafter referred to as CPU) 41, a read-only memory (hereinafter referred to as ROM) 42 that stores coin processing programs, etc., and a random read-only memory (hereinafter referred to as ROM) 42 that stores programs for coin processing, etc. Access memory (hereinafter referred to as R
AM) 43.

The CPU 41 includes a drive control circuit 44 for the motor M1 that rotates the first conveyor belt 6 in forward and reverse directions, and a motor that rotates the second conveyor belt 24. The drive side ti101 path 45 for the motor M2 that performs 1IIllIl of M2 is connected, and each of the photosensors PS1 to PS
s is connected, and the detection signals from each of the 71 sensors PS1 to PS6 are input to the CP IJ 41.

Next, the coin feeding operation will be explained based on the flowchart of FIG.

When the coin C is put onto the first conveyor belt 6 of the first storage section 5, the photo sensor PS2 is detected and turned on (Step 2). M2 is driven in forward rotation (step ■). This converts the detection signal of photosensor ps2 to c p
The program is received by U41 and executed based on the program in ROM42. Subsequently, the motor M1 is driven to rotate normally, and the coins C on the first conveyor belt 6 are sent to the second holding section 23 (step ■), and all the first to fifth timers (
ff+11111) is reset by CPtJ41 (step ■).

When the regulating member 8 rotates counterclockwise and the photo sensor PS1 is turned off (step ■) due to the large amount of input coins C being sent by the first conveyor belt 6, the first timer is activated. (Step ■). It is determined whether or not this first timer has elapsed for a predetermined time, for example, 3 seconds or more (step ■), and if 3 seconds or more has not elapsed, the photosensor PS2 is on and the photosensor PS2 is turned on.

Determine whether PS4 is turned off (step ■)
.

As the regulation member 8 rotates, the coin C is falling from the end of the first conveyor belt 6, so the photosensor PS3 or PS4 is turned on, and the second timer is reset ( Step ■) (In this case, the second timer is not started yet but is reset). Next, it is determined whether the photosensor PS3 is on or not (step 0), and if the coin C is detected at this point and it is on, the third timer is activated (step 2). and,
It is determined whether this third timer is longer than a predetermined time, for example, 0.5 seconds or more (step 0).

If the time on the third timer has not yet elapsed, then
It is determined whether the photosensors PSa and PSs are on and the photosensor PSs is off (step ◎), and if the coin C has not reached the photosensor PS5 and the photosensor PSs is in the off state, the fourth The timer is reset (step [phase]).

Next, 7 filter sensors PS2~ other than photosensor PSI
It is determined whether all PS6s are off (step fD
), now the hard 11C is flowing, so 7 Otosensor PS
Since any of PS2 to PS4 is on, the fifth timer is reset (step ■), and the process returns to step ■, where it is determined whether or not the photosensor Ph is off. Then, in step (2), if the rotation of the regulating member 8 is instantaneous, the first timer is reset (step (2)) because the photosensor Ph is on at the time of this determination. In other words, each timer continues to turn on or off only when its state is continuously detected during the repeated determination operation.

Next, the operation when the flow of coins C is caught will be explained.

A large amount of coins C are sent by the first conveyor belt 6 and the coins C are stuck in a state where the regulating member 8 is kept pressed, the photo sensor PS1 is turned off and the first timer is set for a predetermined period of time or more, for example, 3 seconds or more.''-4 If the time has elapsed (step ■■■), or if the photo sensor PS2 is on and the photo sensor PS3
, PS4 are both turned off and the second timer starts operating (Step 2), and when this second timer exceeds a predetermined vI period, for example, 3 seconds or more (Step 0), the motor M1 is stopped (Step 2). ), this motor M1
By reversing for a predetermined rt, for example 1 m per second (
Step 0), the coin C stuck between the regulating member 8 and the first conveyor belt 6 is returned to the first holding section 5 to clear the coin jam, and after one second, the motor M1 is stopped (step ), then return to step (3), rotate the motor M1 in the normal direction, reset all timers, and continue coin conveyance. Note that, after the motor M1 is stopped, the regulating member 8 returns to its original position more rapidly than the tension spring 16, thereby pushing back the coin C and eliminating the coin jam.

Further, if the coin C is stuck in the introduction chute 21 and the photo sensor PS3 is turned on, and the third timer has elapsed, for example, for 0.5 seconds or more, step
Step o) to temporarily stop the photo sensor PS3, and when the photo sensor PS3 is turned off again (step [phase]), return to step ■ to rotate the motor M1 in the forward direction to continue coin conveyance, and in step ■, start the third timer. Reset.

In addition, the coins C are stagnated in the second storage section 23, that is, the coins C1fi'

Currency C is removed. After that, stop the reverse rotation of motor M2 (step ■), return to step ■ again, and turn motor Mz
, Ml are rotated in the normal direction to continue coin conveyance.

Next, the operation when all the coins C are gone will be explained.

When all of the photosensors P32 to PSs are turned off, the fifth timer is activated (step ■■), and this fifth timer is set to the predetermined DI! If it continues for more than 3 seconds (step ■), it is determined whether the photosensor Ph is on (step Φ), and if the photosensor PSi is on, the motor M1. Stop M2 (step [phase]),
This operation of sending [i ends. If the photo sensor PS1 is off, the fifth timer is reset (step ■), and then the process returns to step ■. If the photo sensor PS1 remains off for 3 seconds or more, the motor M1 is reversed again as described above to clear the coin jam. do.

Note that the feeding operation started when the photosensor PS2 detected that the coin C was inserted into the first holding section 5, but instead of this, when a separate receiving command was obtained, or when a separate When the bottom of the provided reservoir is heard, motor M1. Mz may start.

In addition, in the above-mentioned embodiment, there is provided a coin feeder V which is composed of h1, which is a feature of the present invention, that is, a conveyor belt 24, a separation roller 27, a one-way clutch 27a, a motor M2, etc.
