[0002]

2. Description of the Related Art A conventional coin delivery apparatus is disclosed, for example, in Japanese Utility Model Publication No. 63-49793 (Japanese Utility Model Application No. 60-14899).
There is one described in 3). As shown in FIG. 8A, the apparatus according to this conventional example is provided with a substantially pan-shaped hopper 101 in which a large number of coins (not shown) are stored in a bulk state. The apparatus is further provided with a large rotating plate 102 for sending out coins which is rotated substantially upright in the hopper 101. The rotating plate 102 has a circular base 103 at the center of its surface, and a plurality of coin sending pins 104 protruding from the outer periphery of the surface. The device further includes a knife 105 for sending coins.
Is provided, and the tip of the knife 105 is
3 and is arranged so that the handle of the knife 105 crosses the outer periphery of the rotary plate 102. Thus, when the apparatus is operated, the rotation of the rotating plate 102 in the counterclockwise direction causes the pins 104 to catch and pick up coins in the hopper 101. The coin picked up by the pin 104 is inserted into a pocket 106 formed by the nearby pin 104 and the edge of the base 103, and is carried upward. Thus, the rotating plate 102
The coins carried upward by this are guided by the upper edge of the knife 105, guided to an outlet (not shown), and sent out of the hopper 101.

[0003] Further, as shown in FIG. 8B, the conventional example is provided with a stirring member 107 having a substantially equilateral triangle as a means for stirring coins in the hopper 101. The stirring member 107 is preferably an elastic member such as an elastomer, and has a shape having three claws 108 as shown in the drawing. And a gentle arc 1 between the claws 108
09 is formed. This stirring member 107 is attached to the base 10
When it is attached to the center of the surface of No. 3, the mass of a large number of coins formed in the hopper 101 is broken by the three claw portions 108 extending radially. As a result, the sending efficiency of the coin sending device is improved.

[0004]

However, even in the conventional apparatus as described above, there is a problem that if the coins or medals are large, it is difficult to pick up the coins with the pins. Specifically, the conventional apparatus has a drawback that a large disc such as a one dollar coin is hardly picked up by a pin. In other words, there has been a problem that when the coins or medals of the conventional device become large, the sending efficiency of the coin sending device is significantly reduced. SUMMARY OF THE INVENTION It is an object of the present invention to provide a coin sending device capable of reliably picking up coins or tokens having a large diameter.

FIG. 3 is a cross-sectional view of FIG. 2 taken along line II. FIG. 4 is a perspective view showing a main part of FIG. 5A is a front view of FIG. 4, and FIG. 5B is a cross-sectional end view of FIG. FIG. 6 is a perspective view schematically showing a main part of a second embodiment according to the present invention. FIG. 7 is a front view schematically showing a main part of a third embodiment according to the present invention. FIG. 1 schematically shows a coin delivery device 1 according to an embodiment of the present invention. Reference numeral 1A denotes a large rectangular base plate on which substantially cylindrical stands 1B are fixed upright. A circular support plate 2 is fixed to the front of the stand 1B so as to be inclined substantially upright. Reference numeral 3 denotes a substantially pan-shaped hopper, which is attached to the support plate 2 by screws 4 with a C-shaped ring 2A interposed therebetween. Therefore, the hopper 3 and the support plate 2 stack coins in bulk. A tank 5 for containing is formed. A circular rotary plate 6 is rotatably disposed on the upper surface of the support plate 2 in the tank 5. The rotating plate 6 is provided with a driving device 8 (FIG. 3) for an electric motor provided on the back side of the supporting plate 2.
).

As shown in FIG. 2, a plurality of coin feeding pins 9 are provided upright on the outer peripheral portion 7 of the rotating plate 6 at equal intervals in the circumferential direction. These pins 9 have a height corresponding to the thickness of the coin to be sent out with respect to the upper surface of the rotating plate 6. A circular base 10 is provided at the center of the rotating plate 6. Therefore, the two nearby pins 9, 9 and the base 1
A coin receiving portion 12 is formed by the outer edge 11 of the coin. In other words, the first receiving unit 1 in the present embodiment
2 is the outer edge 1 of the two coin feed pins 9 and 9 and the circular base 10
1.

The first receiving portion 12 picks up coins in the tank 5 one by one and guides them to a coin outlet 13 established above the tank 5. The upper outlet 13 is provided with a knife 14 as shown in FIG. The knife 14 is provided so as to extend across the outer peripheral portion 7 of the rotating plate 6 and has its tip at an upper position in the base portion 1.
0 is disposed so as to be in contact with the outer edge 11. In other words, the upper edge 16 of the knife 14 is provided to extend substantially tangentially to the outer edge 11 at a position above the base 10. Thus, the coin is sent upward through the pin 9 and the outer edge 11 by the rotation of the rotary plate 6. The coins sent upward are further guided from the outer edge 11 of the base 10 to the upper edge 16 of the knife 14 and sent out of the apparatus.

A roller 19 is provided above the exit knife 14.
Are arranged. The rollers 19 are for counting the number of coins passing through the outlet 13. A lower end of a spring-biased operating arm attached to a coin counting switch (not shown) is rotatably provided. As a result of the coin passing through the knife 14 pushing the roller 19 against the spring, the coin counting switch is operated and counting is performed.

Reference numeral 24 shown at the center of FIGS. 1 and 2 is a coin pick-up plate. This pick-up plate 24 is the base 1
0 is attached to almost the entire surface. The coin pick-up plate 24 is for sending coins stored in the tank 5 in a bulk state into the first receiving portion 12 as the rotating plate 6 rotates. The base 10 and the pick-up plate 24 can of course be formed integrally. Also pick plate 24
Are fixed to the base 10 with screws via four screw holes 25. Thus, the coin P located below the tank 5 is picked up by the first receiving portion 12 by the pin 9 and carried upward by the rotation of the rotating plate 6 as shown in FIG. On the other hand, the coin Q somewhat above the tank 5 is picked up by the second receiving portion 28 formed on the pick-up plate 24 and carried upward. Thereafter, the coin P is guided by the upper edge 16 of the knife 14 and sent out of the apparatus, and the coin Q continues to move and falls while making surface contact with the surface of the rotating plate 6 as shown by the chain line in FIG. It is put in the first receiving part 12. First
The coin P put in the receiving portion 12 is sent out of the device as described above.

Here, a specific structure of the pick-up plate 24 will be described with reference to FIGS. In the present embodiment, the pick-up plate 24 is formed by integrally molding a polyacetal resin. It is a matter of course that an elastic body such as another synthetic resin, metal, or elastomer may be used. As shown in detail in FIGS. 4 and 5, the pick-up plate 24 is formed of a slightly thick disk and has a shallow "shi" which constitutes the second receiving portions 26 at substantially equal intervals in the circumferential direction over substantially the entire surface. The four U-shaped depressions are formed. The number of the second receiving portions 26 depends on the size of the pick-up plate 26. The width W of the second receiving portion 26 is formed to be larger than the diameter of one coin Q and smaller than twice the diameter of the coin Q so as to receive one coin Q to be sent out.

In other words, the second receiving portion 26 has a picking edge 27 for picking up the coin Q in the tank 5 by rotation.
Further, a discharging edge 28 for dropping and discharging the coin Q picked up in the second receiving portion 26 to the first receiving portion 12 is formed. Further, an edge 29 is formed which acts to receive the coin Q in the tank 5 into the second receiving portion 26 during rotation.

That is, as shown in FIG. 5A, when the center M of the coin Q is on the second receiving portion 26 side of the vertical line L passing through the lower point of the edge 29, the second receiving portion 26 Can be picked up. The edge 29 during rotation also has a function of preventing the coin Q in the second receiving portion 26 from spilling out.

Further, as shown in FIG.
As the coin Q2 rotates, the coin Q2 falls under its own weight along the ejection edge 28 and enters the first receiving portion 12.
Of course, the angle is adjusted. At this time, the coin Q2 slides down along the discharge edge 28 while making surface contact with the bottom surface of the second receiving portion 26 and the surface of the rotating plate 6.

As shown in FIG. 5B, the depth t of the second receiving portion 26 is adjusted so that at least one coin Q is carried. Further, when the depth t is adjusted so that, for example, two coins Q are carried, the first t
It goes without saying that the number of coins Q supplied to the receiving section 12 increases. When the bottom of the second receiving portion 26 is removed, the accepted coin Q comes into direct surface contact with the surface of the base portion 10.

Since the picking plate 24 is detachably provided on the base 10 with screws, if a plurality of picking plates 24 having different opening widths W and depths t are prepared, they are discarded in accordance with the size of the coin. You will be able to choose.

An inclined surface 31 for coin sliding is formed on the entire outer peripheral edge of the pick-up plate 24. The inclined surface 31 causes coins in the tank 5 to run up when the rotating plate 6 rotates, and stirs these coins. In addition, the inclined surface 31 allows the coin Q in the second receiving portion 26 to slide down smoothly. Although the inclination θ of the inclined surface 31 is set to about 45 degrees as shown in FIG. 5B, it is needless to say that the inclination θ is preferably between 20 degrees and 60 degrees.

A second embodiment according to the present invention is shown in FIG. The pick-up plate 24 in the second embodiment has a protrusion 3 for stirring coins in the tank 5 in addition to the above-described structure.
5 are provided. The projection 35 is for guiding the coins in the tank 5 to the second receiving portion 26 efficiently while stirring them. Although four are formed in the embodiment, it is needless to say that the number is not limited to four. Protrusion 3 for coin stirring
Reference numeral 5 in this embodiment is a substantially inverted T-shape as shown in the lower part of FIG. The protrusion 35 is provided on the picking edge 2 of the picking plate 24.
7 and the discharge edge 28, it is penetrated and attached in the thickness direction of the pick-up plate 24. Specifically, the main body 35 </ b> A of the projection 35 is fitted into the mounting hole 36 of the pick-up plate 24 from below so as to be retained, and is attached so as to protrude from the surface of the pick-up plate 24. In this case, it goes without saying that the rib 35B of the projection 35 is prevented from coming off.

When the projections 35 are formed of urethane rubber or the like, the impact caused by the contact with the coin is absorbed, and the elastic deformation thereof promotes the stirring of the coin. Further, it goes without saying that the entire pickup plate 24 may be formed of an elastic body such as an elastomer. Further, it is a matter of course that part or all of the pick-up plate 24 may be formed of an elastic body such as an elastomer, for example, urethane rubber.

Here, a third embodiment according to the present invention will be further described. FIG. 7 is a schematic view of the third embodiment. The pick-up plate 24 of this embodiment includes a plurality of pins 32 and 33, and these pins 32 and 33 form a second receiving portion 28. . The pins 32 and 33 are provided, for example, directly upright on the pedestal portion 10, and have the same height as the thickness of the two coins to be delivered. It is needless to say that the height of the pins 32 and 33 does not need to be limited to the thickness of two coins, and it is sufficient that at least the height is at least the thickness of one coin. Further, the pins 32 and 33 do not need to be limited to the shape of the pins, and may be deformed, for example, by using protrusions protruding from the surface.

The pin 33 has a contact point A that contacts the outer edge QE of the coin Q, and the pin 32 also has a contact point B that contacts the outer edge QE of the coin Q. In other words, the distance between the contact point A and the contact point B is within a range not exceeding the diameter of the coin Q, so that the coin Q is received during rotation so as not to slip through between the contact points A and B. Conversely, both contacts A and B
Are too close to each other, the coin Q cannot be stably picked up. Accordingly, a straight line L passing through the contact point B and the center point M of the coin Q as shown in FIG.
2 is located on the straight line L1 passing through the contact points B and A. In other words, considering the rotation direction of the pick-up plate 24, the straight line L2 is located at the position where it advances.

As a modification of the third embodiment, pins 32, 33
In addition, if a pin 34 having a contact point C that comes into contact with the outer edge QE of the coin Q is provided, it is of course that more efficient coin picking can be realized. Pin 3 when a new pin 34 is provided
The straight line passing through the contact point C of No. 4 and the center point M1 of the coin Q1 is shown in FIG.
When the coin Q is located on the left side of the vertical line L1 passing through the contact point C of the pin C, that is, on the second receiving portion 28 side as shown in FIG.
You can pick up one. Therefore, by forming the pins 34, the range in which the second receiving portion 28 picks up coins is extended. In addition, the pins 34 prevent the coins contained in the second receiving portion 28 from falling outside.

[0025]

As described above, according to the present invention, it is possible to obtain a large effect that coins having a large diameter in a bulk state in a hopper tank can be reliably and efficiently picked up and sent out. In other words, according to the present invention, there is obtained a great advantage that the sending efficiency of the coin sending device is greatly improved even when the coin or the medal becomes large.
