Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin sorting device used in a vending machine etc., and more specifically, the present invention relates to a coin sorting device used in a vending machine etc. [Prior Art] In vending machines, coins are sorted to determine whether the coins are genuine or not, and to dispense change. It has a built-in coin sorting device that can store coins by denomination. In such a coin sorting device, a coin passage is configured within the device so that the inserted coin moves due to its own weight. Therefore, the coin input port is necessarily located at the highest position of the device, whereas the coin return port from the coin storage section is located at the lowest position.

Fig. 41 shows the overall structure of such a conventional coin sorting device. As shown in the figure, the coin sorting device 2l has a coin input port 22 arranged on the top surface of its main body, and a coin return port 23 arranged on the bottom surface. Inside the device, a coin passage is formed by a coin guide plate, as shown by the broken line, and coins inserted from the coin slot are moved downward by their own weight along this coin passage. It has become. A coin verification mechanism 24 and a coin sorting mechanism 25 are arranged in the middle of this coin passage, and the authenticity and denomination of the inserted coins are determined by the coin verification mechanism 24, and then, based on the results of this determination, the coin distribution mechanism 25 is disposed. 25, the coins are sorted by denomination and stored in the coin storage section 6 located below. The coins stored in this coin storage section 26 are selectively ejected by a coin dispensing mechanism 27 attached to the lower side of this storage section and sent to the coin return slot located at the lowest position. There is. FIG. 42 shows another conventional coin sorting device. The basic structure of this device 120 is the same as that of the conventional example shown in FIG. 41, and corresponding elements are given the same reference numerals. [Problems to be Solved by the Invention] As described above, in the conventional coin sorting device, the coins inserted from the coin slot located at the top of the device body are swept along the coin path inside the device by their own weight. The coins are dropped and stored in a coin storage section formed at the bottom of the device, and the coins are dispensed from a coin return position formed at the bottom of the coin storage section. Therefore, even in a vending machine that incorporates this coin sorting device, the coin input and coin return ports arranged on the front side are at the height positions corresponding to the positions of the coin input and return ports of these coin sorting devices. Therefore, between these,
There is a height difference corresponding to the height of the coin sorting device itself.

For this reason, in conventional vending machines and the like, there has been a problem in that both the coin insertion slot and the coin return slot cannot be set at a height that is convenient for the customer purchasing the product. In other words, if the coin slot side is set at a height that is appropriate for the product purchaser, the coin return slot side will be placed at a height that is difficult for the product purchaser to directly see the returned coins, and is also difficult to take out. It ends up in a side position. On the contrary, if the coin return slot is set at a desired position, the coin input slot will be located too high for the product purchaser.

In view of these conventional problems, it is an object of the present invention to realize a coin sorting device that can freely set the height difference between the coin input port and the coin return port, and thereby and a coin return opening can both be set at desired positions.

[Means for Solving the Problems] In order to solve the above problems, in the coin sorting device of the present invention, a coin transport means for forcibly transporting coins upward is arranged, and this coin transport means Lift the coins inserted from the coin slot to a certain height, or lift the coins ejected from the coin storage section of the device.
From this position, lift it up to a certain height,
This makes it possible to freely change the height positional relationship between the coin input port and the coin return port.

That is, as shown in FIG. 1(A), in the coin sorting device according to the first invention of the present application, there are a thousand coin conveying stages B for conveying the coins inserted from the coin input port A upward; A coin passage C guides the inserted coins conveyed to the upper position by the 1,000-stage coin conveying stage B downward by the coin's own weight, and the input coins that move along the coin passage C are separated by denomination. A sorting means D for sorting, a coin storage means E arranged below the coin passage and storing the input coins sorted by the sorting means D for each denomination, and a coin return means arranged below the coin storage means E. It is characterized by having a mouth F.

Moreover, as shown in FIG. 1(B), in the second invention of the present application, a coin passage C guides a coin inserted from the coin slot A downward by the coin's own weight;
A sorting means D that sorts the inserted coins moving along the coin path C based on the denomination, and a coin storage means that is arranged below the sorting means D and stores the sorted inserted coins for each denomination. E, a coin return port F located above the 1,000-coin storage stage E, and a coin transport means for transporting coins discharged from the 1,000-coin storage stage E to the coin return port F located above. G.

In a third invention of the present application, as the coin conveying means in the second invention, a horizontal belt portion extending substantially horizontally at a position substantially directly below the coin storage means;
This coin conveying belt is characterized by employing an L-shaped coin conveying belt arranged in an I7 shape as a whole so that a vertical belt portion extending in a substantially vertical direction is formed at the conveying downstream end of this horizontal belt portion.

In addition, when adopting such an L-shaped coin conveying belt, a coin conveying roll is arranged at the part where the horizontal belt portion transitions to the vertical belt portion, and the coin conveying roll allows the coin to be conveyed in the horizontal direction by the horizontal belt portion. It is possible to adopt a configuration in which the coins that have been carried are fed toward the vertical belt portion, and in the fourth invention of the present application, the outer circumferential surface for coin conveyance is formed such that both ends thereof are It is characterized by the fact that it is made of a hard material and the central part is made of a soft material.

In the fifth invention of the present application, an auxiliary coin conveyance belt is further arranged in contact with the coin conveyance surface of the vertical belt portion of the L-shaped coin conveyance belt, and the coins are transferred between the coin conveyance surface of the vertical conveyance belt portion and the coin conveyance surface of the vertical belt portion. It is characterized by being conveyed vertically while being sandwiched between auxiliary coin conveying belts.

Further, in the sixth invention of the present application, the L-shaped coin conveying belt is horizontally connected to two conveying belts, a horizontal coin conveying belt constituting a horizontal belt portion and a vertical coin conveying helt constituting a vertical helt portion. It is characterized by a split-type coin conveying belt.

On the other hand, as shown in FIG. 1(C), in the coin sorting device according to the seventh invention of the present application, both coin conveying means in the coin sorting devices according to the first and second inventions are provided. It is characterized by its composition.

[Effect]

In the coin sorting device according to each of the inventions of the present application, the coins inserted from the coin input port A are forcibly moved upward by a certain distance by the coin depositing means B or G5 or both. will be transported towards. Therefore, unlike Yokoi's device in which the coin passage is dropped by its own weight, the height positions of the coin input port and the coin return port can be freely adjusted by changing the amount of coin lift by these coin transport means.

Further, in the coin sorting device according to the third invention of the present application,
An L-shaped conveyor belt is used as the coin conveyor,
The coins ejected from the coin storage means fall onto a horizontal belt section placed directly below the coin storage means, are conveyed by this horizontal belt section toward the vertical belt section, and then,
The vertical bell 1 section transports the coins vertically towards the coin return opening. Therefore, compared to a structure in which the coins ejected from the coin storage means are rolled onto the vertical belt portion by their own weight, the vertical dimension of the device is shortened.

Furthermore, in the fourth invention of the present application, a coin transport roll is arranged at the bending part from the horizontal belt part to the vertical belt part of the L-shaped coin transport belt, and both ends of the outer peripheral surface of this roll are formed of a hard material, Since the central portion is made of a soft material, the conveyor belt is always maintained in an appropriate tension state by both end portions of the roll made of a hard material. In addition, the coins being conveyed from the horizontal belt part to the vertical belt part are transported smoothly to the horizontal belt belt without any problems such as jams because the central part of the roll made of soft material deforms according to the coin's attitude. section to the vertical belt section.

Furthermore, in the fifth invention of the present application, since the auxiliary coin conveying belt is disposed in contact with the coin conveying surface of the vertical belt portion of the L-shaped coin conveying belt, the coin is vertically held between the auxiliary coin conveying belts. conveyed in the direction. Therefore, problems such as coins falling from the coin conveying surface of the vertical belt portion are avoided, and the coins are reliably conveyed vertically.

On the other hand, in the sixth invention of the present application, a split type is adopted as the L-shaped coin conveyance belt, and the coins discharged from the coin storage means fall onto the horizontal coin conveyance belt. is conveyed to the side of the vertical coin conveying belt, and then conveyed in the vertical direction by this vertical coin conveying belt. This split-type coin conveying belt does not require a bend from the horizontal belt section to the vertical belt section unlike in the integrated type, and there is no risk of coins getting stuck in such a section. This means that the coin conveyance direction can be smoothly switched from vertical to vertical.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

First, a first embodiment of the coin sorting device according to the present invention will be described.

(Overall Structure) Figures 2 and 3 show the overall structure of the coin sorting device of this example. As shown in these figures, the coin sorting device 1 of this example is comprised of a vertically elongated rectangular parallelepiped main body 2 and a coin transport mechanism 3 attached to the side surface of the main body. The lower part of the coin transport mechanism 3 protrudes toward the front side, and a coin slot 4 is formed in the vertical direction on the front surface 3a of this protruding portion. The coin transport mechanism 3 also includes a coin verification unit 5 for determining the authenticity and denomination of coins inserted from the coin input slot 4, and a coin verification unit 5 for determining the authenticity and denomination of coins inserted from the coin input slot 4. A counterfeit coin discharge section 6 for discharging the inserted coins is built-in. On the other hand, the device main body 2
From the top side, there is a coin sorting section 7 and a coin storage section 8.
and a coin return section 9 are arranged in this order, and a coin return opening 10 is arranged at the lower end surface of this coin return section 9.

(Coin Conveyance Mechanism Section 3) The structure of the coin conveyance mechanism section 3 is shown in FIGS. 4 to 7. First, as shown in FIGS. 4 and 5, a coin CN inserted into the coin retrieval mechanism 3 from the coin input port 4 formed on the front surface is guided toward the rear surface 3b. A coin passage 11 is arranged. This coin passage 1
A coin lift mechanism 12 is disposed at the rear end portion 11a of the coin lift mechanism 12 adjacent to the device main body 2 side. The coin lift mechanism 12 includes a drive roll 13 horizontally arranged below the rear end of the coin passage 1l, and a coin transport mechanism 3.
A driven roll 14 arranged parallel to the roll 13 at the upper end position, a guide roll 15 arranged parallel to the driven roll l4 slightly below the driven roll 14, and an endless belt 16 stretched across these rolls under constant tension. It consists of

This endless bell}16 is located close to the side of the rear end 11a of the coin passage at its lower end position, and at its upper position it is held close to the side of the device main body 2 by the guide roll 14. The roll is slightly inclined toward the lower end, and then reversed by the driven roll 15 so as to reach the drive roll l3 located at the lower end again. A pair of coin engaging protrusions 16a, 16a are formed on the surface of the endless belt l6 at regular intervals in the conveying direction of the belt. The mutual spacing between these pair of engaging protrusions is
The coins scheduled to be inserted are set so that they can be secured as shown in the figure.

(Counterfeit Coin Discharge Unit 6) Next, referring to FIGS. The configuration of the cargo delivery section 6 will be explained. This counterfeit coin discharging section 6 is for discharging υ1 coins determined to be counterfeit coins by the coin verification section 5 from the coin passage 11. This counterfeit coin discharge section 6 has a movable passage 61 that dominates a part of the coin passage l1, and this movable passage 61 is connected to vertically opposing plates 11 that define both side walls of the coin passage 11.
It is fixed to the tip of the actuating rod 62a of the solenoid 62 so that it can extend and retract in the horizontal direction by penetrating through the solenoid 62. In the normal state in which genuine coins are conveyed, the solenoid 62 is deenergized, and therefore, as shown in FIG. It is located at a protruding position penetrating through the coin passageway 11, and forms a continuous coin passageway 11. However, when a counterfeit coin passes, the solenoid 62 is energized based on the counterfeit coin detection signal from the coin verification section 5, and the solenoid 62 is activated.
2a is attracted. As a result, the movable passage 61 fixed to the tip of the operating iron also retracts, and as a result, the coin passage 11 becomes discontinuous at this position, and counterfeit coins fall downward through the slit portion 63 opened here. (
(See Figure 6(C)).

(Coin Rolling Mechanism 17) Next, the structure of the upper end side of the coin lift mechanism 12 will be described with reference to FIGS. 7(A) and 7(B).

As shown in the figure, a coin rolling mechanism 17 is disposed in this portion, which rotates the coin CN conveyed by the belt 16 by 90 degrees and conveys it toward the apparatus main body 2 side. This mechanism 17 has a ■-shaped groove 171 extending from the reverse side of the bell 16 in a direction substantially perpendicular thereto, and this V-shaped groove 171 has a guide member 172 disposed oppositely. , 173, and an inclined plate 174 disposed at the lower end side of these. The member 172 on one side of the guide member has an upper end surface 172a on which a part of the coin CN fed horizontally from the belt 16 can ride, and forms a V-shaped groove with this upper end surface. It has a curved surface 172c that continues with the slope 172b. Therefore, as shown in the figure, the coin CN sent out in a horizontal state from the bell I-16 first rides on the upper end surface 172a of the guide member 172, and then, due to the coin's own weight, the coin CN is pushed out from the other side into a V-shape. It falls into the groove 171. Then, it falls onto the inclined plate 174 forming the lower end of the V-shaped groove 171, moves on this inclined plate 173, and moves toward the apparatus main body 2. In this way, the coin CN sent out from the belt 16 is guided toward the device main body 2 with its direction rotated by 90 degrees. A coin port 2a communicating with the inside of the device main body 2 is formed at the end of the inclined plate 174, and coins are guided into the device main body 2 through this.

(Structure of Apparatus Main Body 2) Next, the structure of the apparatus main body 2 will be described with reference to FIGS. 8 to 11.

(Coin Sorting Section 7) First, as shown in FIGS. 8 and 9, the device main body 2
In the coin sorting section 7 located at the upper side of the coin distribution section 7, a coin passage 71 is configured to transfer the coins by their own weight from the coin population 2a toward the coin storage section 8 located at the lower side. A plurality of gates for sorting coins are arranged in the middle of the passage 71. Coin aisle 7
1 branches into paths for each denomination on the downstream side. In this example, the input coins are 500 yen and 100 yen depending on the gate group.
Sorted by denominations of yen, 50 yen, and 10 yen, 500 yen aisle 71 (500) and 100 yen aisle 71 (
100), 50 yen aisle 7l (50) and 10 yen aisle 7
1 (10). In addition, in this example, in addition to these passages, the collection passage 71 (collection of money) is blocked, and when coins are continuously inserted, two
The coins after the first coin, and the coins inserted after the coin storage section (to be described later) is full of stored coins, are distributed to this collection passage 71 (collection) side, and this collection passage 7l (collection) is used. The device is stored in a safe (not shown) provided externally below the device main body 2 via the device.

Figure 10 and Figure 10! The structure of the above-mentioned coin passage and gate group will be explained with reference to FIG. It consists of 75. The first gate 72 is disposed at the most upstream side of the coin passage 71, and distributes the input coins to the money collection road 71 (collection) side, or to the other denomination passage 71 (500),
71 (IOOL 71 (50), 71 (10)). This first gate 72 is driven by an actuator (not shown), and under normal conditions, the actuator is deenergized. In this state, the gate 72 is set at the position shown by the solid line in FIG. 10, so that the inserted coins are distributed to the denomination path side.

Next, the second gate 73 passes the input coins to the denomination passage 71.
(10), 71 (100) side, or to the denomination path 7 1 (500), 7 1 (50). As shown in Figure 10, this second
The gate 73 is driven by a solenoid 76 and is set in its protruding position by a spring 77 when the solenoid 76 is in a de-energized state, so that the input coin can be passed through the denomination passage 71 (5
00), 71 (50) side. When the solenoid 76 is energized, it is installed in its retracted position and
Insert coins into denomination passage 71 (100), 71 (10)
Allocate to the side of Next, the third gate 74 controls which of the denomination paths 71 (100) and 71 (10) the coins sent through the second gate 73 are distributed to. When the gate actuator (not shown) is deenergized, the gate 74 is in the position shown in phantom lines in FIG. 10, and when the actuator is energized, it is set in the position shown in solid lines in this figure. Ru. On the other hand, the fourth gate 75 controls which of the denomination paths 71 (500) and 71 (50) the coins sent through the second gate 73 are distributed to. When the gate actuator (not shown) is deenergized, the gate 75 is in the position shown in phantom lines in FIG. 11, and when the actuator is energized, it is set in the position shown in solid lines in this figure. Ru.

Coin sensors 31 and 32 are arranged in the coin passage 71 at a position near the coin population 2a and at a position on the downstream side of the l-th gate 72, respectively, for detecting the passage of coins and the presence or absence of coins. ing.

(Coin storage section 8 and coin return section 9) Next, the coin storage section 8 arranged below the coin sorting section 6 has a number of coin storage tubes (not shown) corresponding to each of the above denominations. ) is built-in.

Each of these storage cylinders is connected to each of the above-mentioned passages 71 (500), 7.
1 (100), 7 1 (50) and 71 (10
), and the coins sent through each passage are stored in a stacked state in the thickness direction, and the coins in passage 71 (acceptance) are
The 00 yen coin storage tube is stored in the above-mentioned safe via a collection passage (not shown) provided in front of the storage cylinder.

In addition, the coin return unit 9 for discharging the coins stored in each storage cylinder of the coin storage unit 8 toward the return port 10 includes:
For example, the mechanism may be the same as that disclosed in Japanese Patent Application Laid-Open No. 54-161995, and is comprised of an opening/closing mechanism that can selectively open and close the opening at the lower end of each storage cylinder.

(Coin Conveyance and Sorting Operation) Next, the operation of the coin sorting device having the above structure will be explained. First, as shown in FIG. 4, when a coin CN is inserted through the coin slot 4, the coin is transferred by its own weight through the coin passage 11 and moves toward the coin lift mechanism 12. . During this movement, the coin verification section 5 installed along the coin path 11 determines the authenticity and denomination of the coin CN. If the coin is determined to be a counterfeit coin, the gate 6 is driven to drop the counterfeit coin from the passage l1 toward the coin return slot lO.

When the coin CN is a genuine coin, the coin moves to the tip of the passage 11 and is stopped there by a stopper or the like (not shown). When the coin reaches this position, or at a desired time earlier, the coin lifting mechanism 1
The driving of the bell l-16 is started, and the drive roll l3 is rotated by a drive motor (not shown), thereby causing the bell l-16 to rotate.
starts moving in the direction of the arrow in FIG. belt 1
6 starts conveying, the coin engaging protrusion 1 on the belt surface
When the coin 6a moves from the lower side of the stopped coin CN toward the upper side, the lower end of the coin CN is caught and conveyed upward.

The coin CN conveyed by the bell l-16 to the vicinity of its upper end position passes through the guide roll 15 and then moves along the inclination of the bell 16 to the side of the device main body 2 in a slightly inclined state. conveyed to the top of the At the position where the belt 16 is reversed along the driven belt 14 at the uppermost end, the transported coin CN comes off the coin engaging protrusion 16a of the belt and falls toward the coin rolling mechanism 17. As described above, the coin rolling machine groove 17 rotates the conveyed coin CN by 90 degrees so that the coin is oriented in the width direction of the main body of the apparatus (see FIG. 7).

After this, the conveyed coins CN are transferred to the coin population 2a of the device main body 2.
The coin enters the coin distribution section 7 of the device main body section 2 through the coin distribution section 2, and rolls through the coin passage 71 due to its own weight. Here, the denomination of the conveyed coin CN has already been determined by the coin verification section 5, and the positions of the coin sorting gates 72, 73, 74, and 75 are set based on the determination result of the coin verification section. .

Therefore, the conveyed coin CN is guided by these gates to the denomination path corresponding to the denomination of the coin, and is stored in the coin storage cylinder of the corresponding denomination in the coin storage section 8 through this path. . In addition, if coins are inserted continuously, 2
Coins after the first one are stored in the storage passage 71 (
storage), and is then stored in a safe outside the device. Similarly, when the storage cylinder for each denomination is full,
The coins you put in are placed in the safe.

Next, the operation of dispensing the coins stored in the coin storage section 8 is as follows.
A coin return unit 9 is driven to drop coins from a coin storage tube in which coins to be dispensed are stored toward a return opening 10.

In this way, in the coin sorting device of this example, the coin input port 4 is set at approximately the same height as the coin return port 1O, and the coins inserted therefrom are transferred to the coin lift machine 12
The coins are lifted up to the top position of the device, and then the coins are moved through the coin passage by their own weight, during which time they are sorted by denomination and stored in the corresponding coin storage cylinders. Therefore, according to the structure of the example, the height position of the coin slot 4 can be set freely by adjusting the lift amount of coins by the coin lift mechanism. Therefore,
It becomes possible to set the coin input port and the coin return port at substantially the same height position.

Further, in this example, coin holding protrusions are formed at equal intervals on the belt that guides the coin lifting mechanism. Therefore,
The coins conveyed through the coin lift are fed into the coin sorting section at intervals of a predetermined time or longer, which is preferable because the coin sorting operation is always performed properly. Furthermore, since the coin verification section and the counterfeit coin discharge port are installed near the coin input port, the counterfeit coins are preferably discharged to the return port immediately without moving within the device.

In addition, in this example, the coins transported by the coin lift mechanism are rotated by the rolling mechanism to adjust the direction of the coins, so the direction of coin insertion at the coin input slot is adjusted to the direction of the coin passage in the main body of the device. There is no need to adjust the coin direction, and the coin slot has the advantage that the direction of the coin slot can be set freely by adjusting the amount of rotation of the coin by this rolling mechanism. In the above example, a description of the control system for driving and controlling each part was omitted, but such a control system is well known and can be constructed from, for example, a one-chip microcomputer; in this case, According to the control program stored in advance in the ROM, signals from the coin verification section and each sensor are input, and control signals corresponding to these human forces are output to control the drive of the coin lift mechanism and the drive of various gates. Just do it like this.

In addition, although the money collection passage 71 (money collection) and the money collection passage (not shown) below it are provided on the front side of the device, it is better to provide them on the back side to supply coins to the coin storage cylinder from the front side. This is preferable because it does not become an obstacle.

Further, in the above example, the coin validation section is installed in front of the coin lift mechanism, but it can also be installed on the coin conveyance path by the lift mechanism or in the coin passage downstream of the lift I structure.

Next, FIG. 12 shows a modification of the first embodiment described above. The basic configuration of the coin sorting device 3I of this example is the same as that of the first example, and therefore, the same reference numerals are given to corresponding components, and detailed explanation thereof will be omitted.

A different feature of the device 31 of this example is that the coin verification section 5 and the counterfeit coin ejection section 6 are not arranged in the coin passage 1l that guides the coins inserted from the coin slot 4 to the lower end of the coin lift mechanism 12. That's true. Therefore, insert coins from the coin slot 4.
The lifted coins are transported as they are by the coin lift mechanism 12. Further, in this example, a cylindrical coin engaging protrusion 16a' is formed on the belt l6. The device of this example can also provide the same effects as the first example described above.

Next, FIGS. 13 and 14 show an outline of yet another embodiment of the first embodiment. In the device 32 of this example, the coin transport path is arranged so that the coin CN inserted from the coin input port 4 is transported to the device main body 2 via the coin transport mechanism 3 while maintaining its posture. The coin rolling mechanism 17 (see FIG. 7) as in the above example is not arranged. The device of this example is characterized by a coin holding protrusion 16A formed on the belt l6 of the coin lift mechanism 12. That is, in this example, the coin path l
1, coin engaging protrusions 16A are formed at equal intervals over the entire width of the belt. In other words, it has a certain slope with respect to the horizontal direction. In this construction device 32, the coin CN inputted from the coin input port 4 is transferred through the inclined coin passage l1 and sent to the bell.
16 and stops there. After that,
It is locked by the retaining protrusion 16A and transported upward. During transportation, the coin is pushed by its own weight against the vertical guide wall 3 disposed on the inclined lower end side of the protrusion 16A.
I was transferred to the 3rd side. It is conveyed in a state in which it is in contact with the guide wall 33 of. At the upper end of this guide wall 33, a coin pocket 2a of the device main body portion 2 is opened. Therefore, the coin conveyed to the upper end by the bell }16 is
The coin is transferred by its own weight on A and enters the device main body 2 through this coin population 2a.

As described above, in the device 32 of this example, the inclined coin holding protrusion 16A is formed on the surface of the belt 16. Therefore, compared to the case where the Hoaikawa protrusions are formed in the horizontal direction, there is an advantage that there is a lower risk of coins riding on the Hoaikawa protrusions falling from the Hoaikawa protrusions. Furthermore, even at the upper end of the belt, the coins that have been transported to the upper end are quickly transferred to the device main body part 2 due to their own weight, making it possible to transport the coins by the belt more efficiently as a whole. This has the advantage that the conveyance speed of the belt can be increased.

FIG. 15 shows another example of the above-mentioned slanted coin-engaging protrusion. In this example, on the surface of the belt 16, a wedge-shaped protrusion 16 having an inclined surface is provided at the center portion thereof.
B is formed. This shaped protrusion 16
Even when B is provided, the above-mentioned coin holding Aigawa protrusion 16
The same effect as in case A can be obtained.

Here, such inclined coin-engaging protrusions 16A, 1
The effect of 6B can also be obtained by the coin sorting device 34 equipped with the coin transport mechanism section shown in FIG. 16. In this device 34, the drive roll 13 and the driven roll 14 are arranged in an inclined state with respect to the horizontal line,
A belt 16 is spanned between these, thereby forming an inclined coin conveyance path. On the surface of the belt, coin holding protrusions 16C are formed at equal intervals in a direction perpendicular to the conveyance direction of the belt. Therefore, these protrusions 16C are inclined with respect to the horizontal line, and thereby the same effect as the above-mentioned protrusions I6A and 16B can be obtained.

Next, FIG. 17 shows a coin sorting device 35 that is equipped with a mechanism for vertically conveying coins without using the above-mentioned coin holding protrusions. As shown in the figure, in the device of this example, semicylindrical protrusions 162, 162 are formed on the surface of the vertically arranged belt 16 to support the pivot shaft 16 in a horizontal state. . A rectangular parallelepiped-shaped packet l63 is suspended from the pivot axis l61. This bucket 163 has an opening 163a on the side of the shaft 16l. Further, a coin stop portion 164 is arranged at the lower end of the belt 1G to hold the coins transferred through the coin passage 1l in a state facing the surface of the belt 16 moving upward. This coin stop part 164 is
It has a pair of stop pieces 164a and 164b arranged facing each other at the same height position, and these stop pieces are supported by pressing springs 165a and 165b, respectively, and are movable in directions away from each other. It has become. And the bottom surfaces of these stop pieces are each
Slanted surfaces 166a and 166b are sloped toward the belt from the lower end located outside both ends of the belt. Incidentally, the buckets 1-163 having this configuration are attached to a plurality of locations on the bell 16 at equal intervals.

The coin conveyance operation by this bell 16 will be explained with reference to FIG. 18. First, as shown in FIG. 18(A), the coin CN that has been transferred through the coin passage 11 is stopped on the coin stop section 164. After this, the packet 163 suspended from the belt l6 rises to the position of the stopped coin CN. At this time, as shown in FIG. 18(B), the protrusions 162, 162 on the belt first hit the inclined surfaces 166a, 166b of the pair of stop pieces, and while pushing them apart against the spring force, Rise. When the pair of stop pieces are pushed apart in this way, the coin CN supported by them falls and enters the packet through the opening 163a, and then, as shown in FIG.
), the coin is conveyed upward in this state.

After the bucket 163 passes through the roll l5 at the upper end, the opening 163a of the packet faces downward, and the coins in the packet naturally fall from this opening into the main body of the device, as shown in FIG. 18(D). He will be transferred to the Division 2 side. In this way, coins can also be conveyed by attaching the packets to the belt l6.

In each of the examples described above, a belt conveying mechanism is used as a coin lifting mechanism, but other known lifting mechanisms may be used instead. Further, in each of the above examples, a coin holding protrusion is formed on the belt surface, or a packet is attached to the belt surface, whereby the coins are held on the belt and conveyed upward. However, the structure of the coin-engaging river may be other than this. Further, in each of the above examples, no mention was made of the drive timing and stop timing of the belt constituting the coin lift mechanism, but this drive control can be individually set according to each application example.

Next, FIGS. 19 to 21 show a second embodiment of the coin sorting device of the present invention.

First, as shown in FIG. 19, the coin sorting device 4 of this example!
is separated from a vertically elongated rectangular parallelepiped-shaped device main body 42 and a coin rift mechanism 43 attached to one side of the main body. Upper surface 421 of device main body 42
A coin slot 422 is open, and a chute 44 for coins is disposed directly above the coin slot 422. At the upper end of this chute 44, there is a coin slot 4 for horizontally loading coins CN.
5 is installed. The device main body part 42 has a coin sorting part 46, a coin storage part 47, and a coin return part 48 built in in this order from the top. This coin return section 4
A chute 49 for return coins having a shape that narrows downward is installed continuously from the lower end of the coin lifting mechanism 8 , and the lower end of this chute 49 communicates with the lower end side of the coin lift mechanism section 43 .

On the other hand, a coin return port 50 is installed on the upper end side of the coin lift mechanism section 43 and is set at approximately the same height as the coin input port 45 described above. 20 and 21 show the internal structure of the coin lift mechanism section 43 described above. As shown in this figure, inside a vertically arranged elongated cylindrical case 431 that guards the coin lift mechanism section 43, there is a driving roll 4 on the lower end side.
32 is arranged, and a driven roll 433 is rotatably arranged on the upper end side, and a conveyor belt 434 is stretched around these. The drive roll 432 is driven by a motor 436 obtained via a speed reduction device 435 consisting of a belt and a pulley.
It is designed to be driven by the decelerated rotation of the On the surface of the conveyor belt 434, pairs of horizontally arranged protrusions 437 for engaging coins are formed at equal intervals in the belt conveyance direction, and the interval between each pair of protrusions is determined by the distance between the coins to be conveyed. The width is set to be narrower than the diameter.

A coin stop part 438 is installed on the lower end side of the conveyor belt 434 so as to face the surface of the belt moving upward, and the coins are discharged from the lower end opening 49a of the return coin chute 49.
Coins that enter the case through an opening 431a formed in the case 431 are transferred onto this coin stop portion 438. On the other hand, at the folded portion on the roll 433 which is the upper end of the conveyor belt 434, the coins that have been conveyed to the upper end by the conveyor belt 434 are separated from the belt surface and guided to the coin return port 50 side. A separation plate 439 is arranged for this purpose.

The coin conveying operation in the coin sorting device 41 of this example, which is arranged in this way, will be explained. First, when a coin CN is inserted from the coin input port 45, the coin falls by its own weight inside the input coin chute 44, reaches the coin pocket 422 of the device main body 42 through the lower end opening, and is passed through there. The coins then pass through the coin sorting section 46 in the main body section 42 of the device. The coin sorting section 46 determines the authenticity and denomination of the inserted coin. The coin whose denomination has been determined is stored in the coin storage section 47.
The coins are stored in the corresponding coin storage cylinder.

If the coin is determined to be a counterfeit coin, it falls directly into the return coin chute 49 via the slag chute.

Next, the coins dispensed from the coin storage section 47 or the coins that are determined to be counterfeit coins and fall down the slug chute fall through the return coin chute 49 and are passed through the lower end opening 49a into the coin lift. Ja side case opening 43
Pass through 1a and enter the case. The coins that have entered the case are transferred on the coin stop part 438 and are transferred to the case inner circumferential wall 43.
It stops when it hits lb. Here, conveyor belt 4
34 is driven at predetermined timing. - The protrusion 437 formed on the surface of the conveyor belt moving in the opposite direction
After hitting the lower end of the coin stopped on 38, the coin is conveyed upward together with the conveyor belt by this protrusion. Coins that have reached the upper end of the conveyor belt 434 are guided from the surface of the conveyor belt to the coin return port 50 side by a dividing plate 439 set there.
It is paid out from o.

As described above, according to the coin sorting device of the wooden example, the coins dispensed from the main body 42 of the device are lifted by the coin lift mechanism 43 to almost the same height as the coin input slot, and then the coins are It is designed to be paid out from the return slot 50. Therefore, by adjusting the amount of coin lift by the coin lift mechanism, the position of the coin return opening can be freely set. Therefore, the coin return port and the coin input port can be set at substantially the same height position.

Next, a third embodiment of the present invention will be described with reference to FIGS. 22 to 24. As you can see from these figures,
Since the coin sorting device 51 of this example is basically the same as that of the above-mentioned second example, corresponding components are given the same reference numerals and their explanations will be omitted. The feature of the device 51 of this example is that the chute 49 for return coins in the second example described above is
Instead, a method was taken to transport the coins horizontally. That is, the coin lift mechanism section 43 in this example
is L-shaped having an upright portion extending vertically along the side surface of the device main body 42 and a horizontal portion extending horizontally from the lower end of the upright portion along the lower surface of the device main body 2,
Inside the L-shaped case 52, one endless conveyor belt 53 is arranged in an L-shape. On the surface of this conveyor belt 53, a pair of coin holding protrusions 437 are formed at equal intervals, similar to the above-described example.

To explain with reference to FIG. 23, the conveyor belt 53 spans over a driven roll 433 at the upper end position, and spans over first and second guide rollers 54 and 55 which are rotatably installed at the lower end position. It is bent almost horizontally toward the bottom side of the device main body 2, and is further spanned over the drive roll 432 at the end in the horizontal direction. The drive roll 432 is driven by the decelerated rotation of a motor 436 obtained through a deceleration device 435 consisting of a belt and a pulley, thereby moving the conveyor belt 53 in the direction indicated by the arrow in the figure. In this way, in this example, a horizontal helt portion 53H is provided between the drive roll 432 and the first guide roll 54, which horizontally transports the coins returned via the coin return unit 48 of the main body of the device. The first guide roller 54 and the driven roll 43
3, a vertical belt portion 53V is provided between the horizontal belt portion 53I and the vertical belt portion 53V to convey the coins conveyed in the horizontal direction toward the coin return port 50 at the upper end.

Here, the first guide roller 54 has large-diameter flanges 54a at both ends of its rotational axis, and a small-diameter cylindrical portion 54b between the two ends.
The conveyor belt 53 is guided by the conveyor belt 53, and the protrusion 437 on the conveyor belt can be passed through at a position therebetween.

In the device 51 of this example configured in this way, coins that fall from the coin return section 48 at the lower end of the device main body section 42 are
The coins fall onto the horizontal belt portion 53H of the conveyor belt 53 and are held by the coin retaining protrusions 437 formed on the belt.
First, it is transported horizontally. It then reaches a vertical belt section 53H of the conveyor belt via the first guide roll 54 and is conveyed upward by this vertical belt section 53H. After reaching the upper end, the separating plate 43
9, the coin is delivered from the belt to the coin return port 5o, and is returned from the coin return port 5o at ζ. Therefore, the device of this example can also provide the same effects as the second example. In addition, in the device of this example, unlike the second embodiment described above, in order to guide the coins ejected from the device main body 42 to the coin lift mechanism 43 side by their own weight, There is no need for an extended return coin chute. That is, since the horizontal belt portion 53l1 is formed so that coins can be conveyed horizontally, there is no need for a vertically long chute for returning coins, which has the advantage that the device size can be reduced accordingly. .

Further embodiments of the present invention are shown in FIGS. 25 to 27. The coin sorting device 81 of this example is basically the same as that of the third example described above, and accordingly, corresponding components are given the same reference numerals and their explanations will be omitted. The feature of the wooden example lies in the configuration of guide rolls 82 arranged to move the conveyor belt 53 from its horizontal belt portion 53H to its vertical belt portion 53V. That is, the second
6 and 27, the guide roll 82 has disk portions 82 at both ends of its rotation axis 82a.
1 is made of a hard material, and the cylindrical portion 822 sandwiched therebetween is made of a softer material. Various modifications of this guide roll 82 are shown in FIGS. 28 to 32. Roll 82 shown in FIG.
3 is a construction in which a bobbin case-like hard part is formed with large-diameter flanges 824 formed at both ends, and a cylindrical soft part 825 is attached between the flanges 824. The roll 826 shown in FIG. 29 has a configuration in which brushes 828 are closely planted in the radial direction on the outer periphery of a small diameter portion of a hard portion 827 shaped like a bobbin case. The roll 831 shown in FIG. 30 has a rod-shaped projection 8 made of the same material as the hard part 832 on the outer periphery of the small diameter part of the hard part 832 shaped like a bobbin case.
33 is shaped to protrude in the radial direction. Third
The roll 834 shown in FIG. 1 is a roll having a large number of disc-shaped protrusions 836 made of the same material formed on the outer periphery of the small diameter part of a fixed part 835 shaped like a bobbin case. Further, the roll 837 shown in FIG. 32 has a large number of blades 839 made of a soft material arranged in the direction of the rotational axis of the roll at equal angular intervals on the outer periphery of the small diameter part of the hard part 838 shaped like a bobbin case. It's a good idea. Note that as the hard material, a metal or a hard resin material can be used, and as the soft material, a resin material such as rubber or sponge can be used.

When using the guide roll 82 configured in this way, the coin CN is moved from the horizontal belt portion 53H to the vertical belt portion 5 in the state shown in FIG. 33 or 34.
It is transported along the bending portion 53R to 3V. That is, as shown in FIG. 33, the coin CN conveyed to this guide roll 82 by the horizontal belt portion 53H is sandwiched between the belt and the cylindrical portion 822 made of a soft material at the center of the roll 82. The vehicle passes through the bend 53R. At this time, the coin CN is not deformed, and therefore, as shown in the figure, the coin CN is conveyed with its leading and trailing ends hitting the belt and its central portion floating. Here, since the coin CN in this state is hitting the cylindrical portion 822 of the soft material, the coin CN in this state is in contact with the cylindrical portion 822 of the soft material.
22 deforms to follow the conveyance posture of the coin.

Therefore, the coins are smoothly conveyed along the bent portion 53R of the belt. Further, although the soft cylindrical portion deforms in this manner, the disk portions 821 at both ends of the roll are made of a hard material and are therefore always maintained in contact with the surface of the bent portion 53R of the conveyor belt. Therefore, the conveyor belt is always maintained under appropriate tension. Similarly, when a plurality of coins are simultaneously conveyed along this belt bent portion 53R, as shown in FIG. 34, the central portion of the roll 82 is greatly deformed, making it difficult to carry out smooth coin conveyance. In this case, both end portions of the roll are always in contact with the surface of the conveyor belt, and the conveyor belt can be maintained under appropriate tension.

On the other hand, for example, as shown in FIG. 35, when a roll 84 made of a hard material is used instead of the roll 82 described above, the outer circumferential surface of the roll 84 hardly deforms. For this reason, the coin is pushed toward the belt 53 by this hard roll outer circumferential surface, and this pressing force may deform the belt 53. If the belt 53 side is deformed in this way, the belt 53 separates from the outer circumferential surface of the roll 84, so that the belt is no longer maintained in an appropriate tension state. Furthermore, the belt may vibrate and become a source of noise. In order to avoid this situation, the bent portion 53 of the belt should be
It becomes necessary to further add a tension adjustment mechanism to R. FIG. 36 shows a situation in which a plurality of coins are simultaneously conveyed along this belt bent portion 53. Even in this case, smooth coin conveyance cannot be expected, and the belt cannot be properly conveyed. Nor can it be held in tension. On the other hand, it is possible to form the entire roll 84 from a soft material, but in this case, it may become impossible to apply sufficient tension to the conveyor belt, which is not preferable.

In this way, in this example, the guide roll 82 whose center portion is made of a soft material and whose end portions are made of a hard material is arranged at the bent portion 53R of the conveyor belt, so that the belt can be properly adjusted. It becomes possible to smoothly transport coins while maintaining a certain tension state.

This is particularly suitable for conveying coins at high speed.

Hoshiko Zao Arashiaki FIG. 37 shows yet another embodiment of the invention.

The coin sorting device 9l of this embodiment is basically the same as that of the fourth embodiment described above (see FIG. 25), and accordingly, corresponding components are given the same reference numerals and their explanations will be omitted. Omitted. The feature of the device 9l of this example is that a driven belt 92 is added facing the surface of the vertical belt portion 53V of the conveyor belt 53, and the coins are conveyed in the vertical direction with the coins sandwiched between these belts. At the point. That is, as shown in FIG. 37, the driven belt 92 is stretched between the rolls 93 and 94, and the driven belt 92 is held against the surface of the vertical belt portion 53V of the above-mentioned conveyor belt by the pressing spring 95. It is configured to be pressed with a constant force by a pressing plate 96 supported by. A holding plate 97 is disposed on the back side of the vertical belt portion 53V of the conveyor belt so that the belt portion 53V does not bulge due to this pressing force. Note that in this example, the conveyor belt 53
The surface of the coin is not formed with the coin-shaped protrusions as in each of the above examples. Further, a guide plate 98 is arranged between the guide roll 82 and the roll 94 of the driven belt, and a guide plate 98 is arranged at the upper end position of both belts 53 and 92 to separate coins from the surface side of the conveyor belt 53. A minute M plate 99 is arranged to guide the coin return port 50 side.

In the device 9l of this example, which has been exploited in this way, the coins conveyed from the horizontal belt portion 53H of the conveyor belt to the vertical belt portion 53V side via the guide roll 82 are transferred to the vertical belt portion 53V of the conveyor belt. , driven belt 9
2 and is conveyed upward in this state. The coins conveyed to the upper ends of these belts are separated from the transport belt by the separating plate 99, fall to the coin return port 50, and are returned from the coin return port 50. As described above, according to the device of this example, when the coins are conveyed vertically using the coin holding protrusions as in each of the above-mentioned examples, it is possible that the coins will fall off the protrusions during vertical conveyance. This avoids danger and makes it possible to reliably transport coins vertically. FIG. 38 shows a modification of the above example.

This coin sorting device 100 has a configuration in which a single roller 101 is used as the guide roll 82 of the conveyor belt and the roller 94 on the lower end side of the driven belt, and the manufacturing cost can be reduced accordingly. It also has the advantage of simplifying the structure.

1st Toyomi Benefits Officer Next, FIG. 39 shows yet another embodiment of the present invention. The coin sorting device 111 of this example is basically the same as the device according to the third example (see FIG. 22), so corresponding parts are given the same reference numerals and Detailed explanation will be omitted. The features of the device 111 of this example are as follows:
The L-shaped conveyor belt 53 has a divided structure consisting of a first conveyor belt 112 forming its horizontal belt portion 53I1 and a second conveyor belt 113 forming its vertical belt portion 53V. As shown in the figure, the first
The conveyor belt 112 is horizontally spanned between the drive roll 432 and the driven roll 114, and the second conveyor belt 113 is connected to the drive roll 115 and the driven roll 4.
It spans vertically between 33 and 33. Coin holding protrusions 437 are formed at equal intervals on the surface of the second conveyor belt. Driven roll 11 on the side of the first conveyor belt
4 and the drive side roll 115 on the second conveyor belt side are:
Through a power transmission mechanism 116 consisting of a belt and a pulley,
They are connected so that they rotate in the same direction. Also, the first
In order to smoothly guide the coins from the second conveyor belt 112 to the second conveyor belt 113, a guide plate l17 is arranged between them, and with respect to the guide surface of this guide plate, The coin transport roll 11 is moved by the pressing force of the roller spring.
8 are in contact with each other. This coin transport roll 118 is made of a soft material.

In the device N111 having this configuration, the bent portion 53R of the conveyor belt as in the third to fifth embodiments described above is not formed. Therefore, the transition from horizontal conveyance to vertical conveyance of coins can be smoothly performed. For example, unlike the guide rolls in the example described above, the conveyor roll 118 does not need to have the function of holding the conveyor belt in an L-shape with a constant tension, but merely has the function of conveying coins. It can be formed using a soft material suitable for transporting coins. In summary, the device of this example has the advantage that coins are smoothly transported without becoming jammed at the transition portion from horizontal transport to vertical transport.

FIG. 40 shows a modification of the apparatus using such a split conveyor belt. The device 121 in this example is
As can be seen from the figure, the drive side roll 115 at the lower end of the second conveyor belt 113 has the function of the coin conveyor roller 11B, thereby omitting the coin conveyor roller ll8. For this purpose, in this example, the rotation of the driven roll 114 on the side of the first conveyor belt is reversed via the gear train 122 and transmitted to the drive side roll 115 of the second conveyor belt, thereby: The second conveyor belt is moved in the direction indicated by the arrow in the figure. The device having this configuration has the advantage that the manufacturing cost can be reduced by not requiring a coin conveying roll, and the structure is also simple.

〔Effect of the invention〕

As explained above, in the coin sorting device according to each invention of the present application, a coin transporting means for forcibly transporting coins upward is arranged, and the coins inserted from the coin slot are handled by this coin transporting means. Lift it to a certain height,
Alternatively, the coins discharged from the coin storage section of the device are lifted up to a certain height from this position.

Therefore, according to the present invention, it is possible to freely set the height positional relationship between the coin input port and the coin return port. Therefore, if the device of the present invention is applied to a vending machine or the like, it is preferable because both the coin input slot and the coin return slot can be placed at a height position that is desirable for the product purchaser.

Further, in the coin sorting device according to the third invention of the present application, an L-shaped conveying belt is adopted as the coin conveying means, and the coins discharged from the coin storage means of the device are transferred to the horizontal belt portion arranged directly below the L-shaped conveying belt. The coins fall on the horizontal belt, are conveyed by the horizontal belt toward the vertical belt, and are then conveyed vertically by the vertical belt toward the coin return slot. Therefore, compared to a structure in which the coins ejected from the coin storage means are transferred to the vertical belt portion by their own weight, the vertical dimension of the device can be shortened and the device can be made compact.

Furthermore, in the fourth invention of the present application, a coin conveying roll is arranged at the bending part of the L-shaped coin conveying belt from the horizontal belt part to the vertical belt part, and both ends of the outer peripheral surface of this roll are formed of a hard material, The central part is made of a soft material. Therefore, the conveyor belt can be maintained at an appropriate tension state at all times by the hard end portions of the roll made of a hard material, and the coins conveyed from the horizontal belt portion to the vertical belt portion can be transported by the roll made of a soft material. Since the central portion deforms according to the attitude of the coin, it is possible to convey the coin without any problems such as clogging.

Furthermore, in the fifth invention of the present application, an auxiliary coin conveyance belt is disposed in contact with the coin conveyance surface of the vertical belt portion of the L-shaped coin conveyance belt, and the coins are conveyed in the vertical direction with the coins sandwiched between them. It looks like this. Therefore, problems such as coins falling from the coin conveying surface of the vertical belt portion are avoided, and it is possible to reliably convey the coins vertically.

On the other hand, in the sixth invention of the present application, a split type is used as the L-shaped coin conveying belt, and there is no need to form a bending portion from the horizontal belt portion to the vertical helt portion as in the integrated type. Therefore, there is no risk of coins getting stuck in such a portion, and the coin conveying direction can be smoothly switched from horizontal to vertical.
