Description

Coin dispensing device

[0001] The present disclosure relates to a coin dispensing device.

[0002] There is a coin dispensing device incorporated in a vending machine, a coin counting device, etc., which aligns the inserted or stored coins and dispenses them one by one.

[0003] For example, Patent Document 1 discloses a carrying disk type coin discharging device that stores coins in a hopper case above a rotating disk (carrying disk).

[0004] Also, Patent Document 2 discloses a space-saving coin dispensing device. This coin dispensing device includes a hopper case for storing coins, a spiral member rotatably disposed in the hopper case with its rotation axis inclined, and a cylindrical member disposed obliquely below the spiral member such that its center line coincides with the rotation axis of the spiral member.

[0005] Japanese Patent Application Laid-Open No. 11-195155, Patent No. 4741820

[0006] However, in the coin discharging device (coin dispensing device) described in Patent Document 1, since a carrying disk is provided below the hopper case, the outer shape is relatively large in structure and it is difficult to save space.

[0007] Also, in the coin dispensing device described in Patent Document 2, a phenomenon occurs in which coins stand up along the rotation axis of the spiral member in a state where a plurality of coins overlap inside the cylindrical member (hereinafter referred to as "coin standing phenomenon"), and there is a possibility that the coins cannot be dispensed. In the coin dispensing device described in Patent Document 2, it is difficult to eliminate the coin standing phenomenon only by the rotation of the spiral member, and it is difficult to recover from the coin standing phenomenon by itself.

[0008] Therefore, an object of the present disclosure is to provide a coin dispensing device that saves space and can recover from the coin standing phenomenon by itself.

[0009] To solve the above problems, a coin dispensing device according to a first aspect of the present invention comprises: a coin storage section having a lower opening from which coins can be discharged and capable of storing coins; a rotating member formed in a cylindrical shape having an upper end opening and a lower end opening, positioned below the lower end opening of the coin storage section, and internally partitioning a space that allows the circulation of coins discharged from the lower end opening of the coin storage section, and capable of rotating about a rotation axis; a driving means for rotating the rotating member about the rotation axis; and a fixed cylindrical member formed in a cylindrical shape that partitions a space communicating with the lower end opening of the rotating member, and is fixedly provided at a position adjacent to the lower end opening of the rotating member, wherein the central axis of the fixed cylindrical member is inclined with respect to the rotation axis of the rotating member.

[0010] A second aspect of the present invention is a coin dispensing device according to the first aspect, wherein the lower end opening of the rotating member has a smaller diameter than the upper end opening, and the inner circumferential surface of the rotating member is tapered.

[0011] A third aspect of the present invention is a coin dispensing device according to the first or second aspect, wherein the center of the lower end opening of the rotating member is located on the rotation axis of the rotating member, and the center of the upper end opening of the rotating member is eccentric from the rotation axis of the rotating member.

[0012] A fourth aspect of the present invention is a coin dispensing device according to the first or second aspect, wherein the rotating member has ribs extending spirally along the inner circumferential surface, projecting radially inward from the inner circumferential surface, and the ribs extend along the rotational direction of the rotating member from the upper end opening to the lower end opening.

[0013] According to this disclosure, it is possible to provide a coin dispensing device that is space-saving and capable of recovering on its own from the coin-standing phenomenon.

[0017] <Coin Dispensing Device> Figure 1 is an external perspective view of a coin dispensing device according to one embodiment of the present invention. Figure 2 is a top view of the coin dispensing device. Figure 3 is a cross-sectional view taken along the line III-III in Figure 1. Figure 4 is an enlarged view of the main part of Figure 3. Figure 5 is a perspective view of the rotating member and the fixed cylindrical member. Figure 6 is a cross-sectional view taken along the line VI-VI in Figure 5. Figure 7 is a perspective view of the coin dispensing plate.

[0018] As shown in Figures 1 and 2, the coin dispensing device 10 according to one embodiment of the present invention is a thin device with a length of about 50 mm in the width direction (Z direction), and is built into a vending machine or coin counting device, etc., and aligns the inserted or stored coins and dispenses them one by one. The coin dispensing device 10 of this embodiment dispenses coins of the same size (for example, of the same type). Note that "coins" may also be referred to as "coins" or "medals". Also, "alignment" means stacking the coins (see Figure 8(A)).

[0019] As shown in Figures 1 to 4, the coin dispensing device 10 comprises a coin storage section 11 capable of storing coins, a rotating member 12 positioned below the coin storage section 11, a motor (driving means) 13 for rotating the rotating member 12, and a fixed cylindrical member 14 positioned below the rotating member 12. In addition to the above, the coin dispensing device 10 of this embodiment also comprises a coin dispensing plate 15 positioned below the fixed cylindrical member 14. Furthermore, the coin dispensing device 10 comprises a support 16 that supports the coin storage section 11, the rotating member 12, the motor 13, the fixed cylindrical member 14, and the coin dispensing plate 15. The coin dispensing device 10 aligns the coins inserted into or stored in the coin storage section 11 within the fixed cylindrical member 14 using the rotating member 12, and then dispenses them one by one using the coin dispensing plate 15.

[0020] (Coin Storage Section) As shown in Figures 1 to 3, the coin storage section 11 partitions a storage space 17 capable of storing coins inside and is fixedly supported by a support 16. The coin storage section 11 has a lower opening 18 at its lower end from which coins can be discharged. The coin storage section 11 has an upper opening 19 at its upper end from which coins can be inserted. It is preferable that the coin storage section 11 has a shape in which the area (cross-sectional area) in a cross-section perpendicular to the vertical direction decreases from top to bottom. In this embodiment, the coin storage section 11 from the middle part in the height direction to the lower end has a hopper shape (funnel shape) that decreases from top to bottom when viewed from the width direction (Z direction) (hereinafter referred to as "side view"). In this embodiment, the upper opening 19 opens upward, but it is not limited to this, and any opening that allows coins to be inserted into the storage space 17 is acceptable.

[0021] As shown in Figure 3, the coin storage section 11 has front and rear inclined walls 11a and 11b that are closer to each other as you move from top to bottom in a side view. A lower opening 18 is formed at the lower end of the front inclined wall 11a. In this embodiment, the lower opening 18 is formed in a circular shape and opens in a direction inclined with respect to the vertical (in this embodiment, downward and forward). The lower end of the rear inclined wall 11b is continuous with the lower opening 18 at the bottom of the front inclined wall 11a and is shaped to guide coins moving downward along the inner wall surface of the inclined wall 11b to the lower opening 18.

[0022] (Rotating Member) As shown in Figures 4 to 6, the rotating member 12 is a member for agitating the coins discharged from the lower opening 18 of the coin storage section 11 and aligning the coins, and is positioned below the lower opening 18. The rotating member 12 is formed in a cylindrical shape having an upper end opening 20 and a lower end opening 21, and internally partitions a space (rotating member space) 22 that allows the circulation of coins discharged from the lower opening 18 of the coin storage section 11. In the following description, in order to distinguish it from the opening and space of the fixed cylindrical member 14 which will be described later, the "upper end opening 20" of the rotating member 12 will be referred to as the "first upper end opening 20", the "lower end opening 21" as the "first lower end opening 21", and the "space 22" as the "first space 22".

[0023] As shown in Figures 5 and 6, the first upper opening 20 and the first lower opening 21 are formed in a circular shape. The rotating member 12 is positioned below the lower opening 18 such that the first space 22 communicates with the lower opening 18 of the coin storage section 11. The rotating member 12 is positioned so that its rotation axis CL1 is perpendicular to the surface constituting the lower opening 18 of the coin storage section 11, and is rotatably supported by the support 16. That is, the rotation axis CL1 of the rotating member 12 is inclined with respect to the vertical direction (in this embodiment, inclined from rear-upper to front-down). The rotating member 12 is rotatable about a predetermined rotation axis CL1 by receiving power from the motor 13.

[0024] In this embodiment, the first lower end opening 21 of the rotating member 12 has a smaller diameter than the first upper end opening 20. The diameter of the first lower end opening 21 is slightly larger than the diameter of a coin. The inner circumferential surface 12a of the rotating member 12 is formed in a tapered shape, becoming smaller from the first upper end opening 20 towards the first lower end opening 21. In this embodiment, the upper end surface (the surface on which the first upper end opening 20 is formed) and the lower end surface (the surface on which the first lower end opening 21 is formed) of the rotating member 12 are parallel to each other and perpendicular to the rotation axis CL1. That is, the height of the rotating member 12 in the axial direction (the direction in which the rotation axis CL1 extends) is constant. The tapered inner circumferential surface 12a may include a region of a certain diameter between the first upper end opening 20 and the first lower end opening 21. Furthermore, in this embodiment, the first lower end opening 21 of the rotating member 12 is formed to have a smaller diameter than the first upper end opening 20, but it is not limited to this, and for example, it may be cylindrical with the same diameter.

[0025] In this embodiment, the center O1 of the first lower end opening 21 of the rotating member 12 is located on the rotation axis CL1 of the rotating member 12. The center O2 of the first upper end opening 20 of the rotating member 12 is eccentric from the rotation axis CL1 of the rotating member 12. In this embodiment, the center O2 of the first upper end opening 20 of the rotating member 12 is eccentric from the rotation axis CL1, but this is not the only way to do so, and the center O2 of the first upper end opening 20 may be located on the rotation axis CL1.

[0026] The rotating member 12 of this embodiment has a rib 23 that extends spirally along the inner circumferential surface 12a, projecting radially inward from the inner circumferential surface 12a. The rib 23 extends along the rotational direction of the rotating member 12, from the first upper end opening 20 side toward the first lower end opening 21 side. Specifically, in this embodiment, as shown by the white arrow A in Figure 5, when the rotational direction of the rotating member 12 is clockwise in a top view, the rib 23 extends spirally clockwise from the first upper end opening 20 side toward the first lower end opening 21 side. In this embodiment, the rotating member 12 is provided with a rib 23, but it is not necessary to provide a rib 23.

[0027] (Driving means) As shown in Figure 3, the motor (driving means) 13 is a driving means for rotating the rotating member 12 and is fixedly supported on the support body 16. The motor 13 rotates the rotating member 12 around the rotation axis CL1. In this embodiment, a gear 24 (see Figure 5) is provided on the outer circumferential surface of the rotating member 12. The gear 25 fixed to the shaft of the motor 13 is capable of transmitting power (rotation) to the gear 24 of the rotating member 12 via multiple gears. In addition, in this embodiment, the power of the motor 13 is used not only for the rotation of the rotating member 12 but also for the sliding movement of the coin dispensing plate 15, which will be described later. Note that the method of transmitting power from the motor 13 to the rotating member 12 is not particularly limited and may be transmitted via a belt, for example.

[0028] (Fixed cylindrical member) As shown in Figures 4 to 6, the fixed cylindrical member 14 is a member positioned in the part that stores coins aligned by the rotating member 12. The fixed cylindrical member 14 is formed in a cylindrical shape having a circular lower end opening 27 and an upper end opening 28, and internally partitions a space (space of the fixed cylindrical member) 26 that communicates downward from the first lower end opening 21 of the rotating member 12. This space 26 allows the circulation of coins discharged from the first lower end opening 21 of the rotating member 12. The fixed cylindrical member 14 is positioned adjacent to the lower part of the first lower end opening 21 of the rotating member 12 and is fixedly supported (fixedly provided) by the support 16. In the following explanation, in order to distinguish it from the opening and space of the rotating member 12, the "upper end opening 28" of the fixed cylindrical member 14 will be referred to as the "second upper end opening 28," the "lower end opening 27" as the "second lower end opening 27," and the "space 26" as the "second space 26."

[0029] The inner circumferential surface 14a of the fixed cylindrical member 14 extends continuously from the second lower end opening 27 and perpendicular to the second lower end opening 27. That is, the central axis CL2 of the fixed cylindrical member 14 extends perpendicular to the lower end surface of the fixed cylindrical member 14 (the surface on which the second lower end opening 27 is formed). The upper end surface of the fixed cylindrical member 14 (the surface on which the second upper end opening 28 is formed) is not perpendicular to the central axis CL2 of the fixed cylindrical member 14, but is inclined.

[0030] The fixed cylindrical member 14 is positioned such that its second upper end opening 28 is adjacent to and facing the first lower end opening 21 of the rotating member 12. That is, the central axis CL2 of the fixed cylindrical member 14 is inclined with respect to the rotation axis CL1 of the rotating member 12. In this embodiment, as shown in Figure 6, in a side view, the central axis CL2 of the fixed cylindrical member 14 is inclined at an obtuse angle with respect to the rotation axis CL1 of the rotating member 12, and extends diagonally downward and forward of the rotation axis CL1. The central axis CL2 of the fixed cylindrical member 14 is also inclined with respect to the vertical direction (in this embodiment, inclined from rear-upper to front-down).

[0031] The height of the fixed cylindrical member 14 along its axial direction (the direction in which the central axis CL2 extends) is set such that when the coin stands upright within the second space 26 of the fixed cylindrical member 14, points P1 and P2 (see Figure 8(B)) located at the center height along the axial direction of the central axis CL2 on the peripheral edge of the coin are close to or in contact with both the fixed cylindrical member 14 and the rotating member 12.

[0032] As shown in Figure 6, a groove 29 is formed on the lower end surface of the fixed cylindrical member 14 in this embodiment, which allows the movement of coins forward (in the direction of coin delivery) from the second space 26. The groove 29 extends from the second space 26 to the front surface of the fixed cylindrical member 14. In this embodiment, a groove 29 is provided on the fixed cylindrical member 14, but this is not the only way to go, and the groove 29 may be omitted.

[0033] (Coin Dispensing Plate) As shown in Figures 4 and 7, the coin dispensing plate 15 is positioned below the fixed cylindrical member 14 and is supported by a support 16 so as to be slidable back and forth (in the direction indicated by the white arrow B in Figure 4) along the extending direction of the lower end surface of the fixed cylindrical member 14 in a side view. The coin dispensing plate 15 slides back and forth in response to power from a drive source (motor 13 in this embodiment). The shape of the coin dispensing plate 15 is not particularly limited and should be a shape that can dispense the coin located at the bottom of the coins aligned (stacked) inside the fixed cylindrical member 14 forward (in the direction indicated by the white arrow C in Figure 4).

[0034] For example, the coin dispensing plate 15 of this embodiment is formed in a plate shape, as shown in Figure 7. One surface 15a of the coin dispensing plate 15 has a groove 30 that is recessed and extends from the central portion 15b toward one side (direction A shown in Figure 7). The groove 30 is open to the aforementioned one side of the coin dispensing plate 15. The width of the groove 30 (length in direction B) is slightly larger than the diameter of the coin 1 (shown by a dashed line in Figure 7). That is, the groove 30 is formed to a size that allows the coin 1 to move from the central portion 15b toward the aforementioned one side.

[0035] As shown in Figure 4, the coin dispensing plate 15 is positioned below the fixed cylindrical member 14, perpendicular to the axial direction of the fixed cylindrical member 14 (the axial direction of the central axis CL2), such that one side (direction A shown in Figure 7) coincides with the coin dispensing direction (direction indicated by the white arrow C in Figure 4). The coin dispensing plate 15 is supported by the support 16 so as to be able to slide back and forth (in the direction indicated by the white arrow B in Figure 4) between a rear position (the position of the coin dispensing plate 15 shown in Figure 4) and a front position (not shown).

[0036] In the rear position, the central portion 15b of the coin dispensing plate 15 faces the second lower end opening 27 of the fixed cylindrical member 14. That is, in the rear position, the innermost region of the groove 30 of the coin dispensing plate 15 faces the second lower end opening 27 of the fixed cylindrical member 14. In the rear position, the coin dispensing plate 15 allows the lowest coin among the coins aligned inside the fixed cylindrical member 14 to be received into the groove 30. In the front position, at least a portion of the central portion 15b of the coin dispensing plate 15 is exposed to the front of the second lower end opening 27 of the fixed cylindrical member 14.

[0037] Next, we will explain the movement of the coin dispensing device 10 and the coins until they are dispensed from the coin storage section 11.

[0038] Figure 8 is an explanatory diagram of a coin dispensing device, where (A) shows the state in which coins are stacked and aligned, and (B) shows the coin standing phenomenon.

[0039] First, let's explain the case where coins are dispensed without the coin-standing phenomenon occurring.

[0040] Coins stored in the coin storage section 11 move along the front and rear inclined walls 11a and 11b of the coin storage section 11 to the lower opening 18. Coins that have moved from the lower opening 18 to the first space 22 of the rotating member 12 are agitated by the rotating member 12 and aligned in the second space 26 of the lower fixed cylindrical member 14 (see Figure 8(A)). Of the coins 1 stacked in the second space 26 of the fixed cylindrical member 14, the single coin 1a located at the bottom is positioned in the groove 30 of the central part 15b of the coin delivery plate 15 at the back. When the coin delivery plate 15 slides to the front position in this state, the single coin 1a in the groove 30 moves forward from the central part 15b of the coin delivery plate 15 due to inertia and is delivered forward.

[0041] Next, we will explain how to recover on your own if the coin-standing phenomenon occurs. Note that the process is the same as described above until the coins are agitated by the rotating member 12, so we will omit that explanation.

[0042] As shown in Figure 8(B), the coins 1 agitated by the rotating member 12 may stand upright on the coin dispensing plate 15. In other words, the coin standing phenomenon may occur. In this state, the coins 1 receive a rotational force from the rotating member 12 and rotate around the central axis CL2 of the fixed cylindrical member 14, with the part in contact with the coin dispensing plate 15 as the contact point. Since the central axis CL2 of the fixed cylindrical member 14 is inclined with respect to the rotation axis CL1 of the rotating member 12, points P1 and P2 (the positions furthest from the central axis CL2) located at the central height along the axial direction of the central axis CL2 on the peripheral edge of the coin 1 have one point P1 approaching or in contact with the rotating member 12, and the other point P2 approaching or in contact with the fixed cylindrical member 14. For this reason, one side of the coin 1 on the P1 side receives a rotational force from the rotating member 12, but the other side on the P2 side does not receive a rotational force from the rotating member 12 and tries to stay in place by contacting the fixed cylindrical member 14. As a result, coin 1, which was exhibiting the coin-standing phenomenon, becomes unbalanced and falls over, thus resolving the coin-standing phenomenon.

[0043] In the coin delivery device 10 configured as described above, since the central axis CL2 of the fixed cylindrical member 14 is inclined with respect to the rotation axis CL1 of the rotating member 12, when a coin standing phenomenon occurs, it is possible to prevent the coin from rotating about the rotation axis CL1 of the rotating member 12. If the coin rotates about the rotation axis CL1 of the rotating member 12, it is difficult to eliminate the coin standing phenomenon. However, in the coin delivery device 10 according to the present disclosure, the coin can be rotated about an axis (central axis CL2) inclined with respect to the rotation axis CL1 of the rotating member 12. Therefore, the coin 1 in the coin standing phenomenon becomes unbalanced and falls, and the coin standing phenomenon is eliminated.

[0044] In addition, since the coin delivery device 10 stirs and aligns the coins with the rotating member 12 formed in a cylindrical shape, it is possible to significantly save space, unlike the case of using a carrying disk. For example, as in the present embodiment, the length in the width direction (Z direction) of the coin delivery device 10 can be suppressed to about 50 mm.

[0045] Therefore, according to the present embodiment, it is possible to provide a coin delivery device 10 that saves space and can recover from the coin standing phenomenon by itself.

[0046] In addition, the first lower end opening 21 of the rotating member 12 has a smaller diameter than the first upper end opening 20, and the inner peripheral surface 12a of the rotating member 12 is formed in a tapered shape. Therefore, unlike the case where the rotating member 12 has a substantially constant diameter cylindrical shape, a space can be secured in the first space 22 of the rotating member 12 to allow the coins to be stirred to escape to the outer side in the radial direction. As a result, the coins standing vertically (not intersecting with the axial direction of the rotation axis CL1) in the first space 22 of the rotating member 12 are likely to fall.

[0047] Further, the center O1 of the first lower end opening 21 of the rotating member 12 is located on the rotation axis CL1 of the rotating member 12, and the center O2 of the first upper end opening 20 is eccentric from the rotation axis CL1 of the rotating member 12. Therefore, in the cross section of the rotating member 12 (see FIG. 6) passing through the center O2 of the first upper end opening 20 and along the rotation axis CL1, the inner peripheral surface 12a of the rotating member 12 is asymmetric with respect to the rotation axis CL1. Thus, when the rotating member 12 is rotated about the rotation axis CL1, its inner peripheral surface 12a rotates in a biased state, so that the coins can be efficiently agitated within the first space 22 of the rotating member 12.

[0048] Further, the rotating member 12 has ribs 23 extending in a spiral shape, and the ribs 23 extend along the rotation direction of the rotating member 12 from the first upper end opening 20 side toward the first lower end opening 21 side. Therefore, when the rotating member 12 is rotated, the coins contacting the ribs 23 within the first space 22 of the rotating member 12 are guided upward along the ribs 23. Thereby, the coins can be efficiently agitated within the first space 22 of the rotating member 12.

[0049] As described above, the present invention has been described based on the above-described embodiment, but the present invention is not limited to the content of the above-described embodiment, and can be appropriately changed without departing from the scope of the present invention. That is, other embodiments, examples, operation techniques, etc. made by those skilled in the art based on this embodiment are of course all included in the scope of the present invention.
