FIG. 3 is a perspective view showing the coin transport device 100 in a state where coins C are inserted. 1 to 3, the lid 30 is in an open state.

As shown in FIG. 1, the coin transport device 100 feeds out coins C inserted from the upper part to the lower part, and separates and feeds out a plurality of coins C fed in one by one. . And by rotation of the rotor 20 arrange | positioned inside the cylindrical part 10, the coin C is conveyed along the side wall 11 which is an inner peripheral wall of the cylindrical part 10, and falls one by one in the fall hole H (refer FIG. 10). It is something that you pay out. The rotor 20 usually rotates in the normal rotation direction a (see FIG. 10).

Specifically, the coin transport device 100 includes a cylindrical portion 10 having a side wall 11 and a bottom wall 12, and a rotor 20 that is disposed inside the cylindrical portion 10 and has the center of the cylindrical portion 10 as a rotation center.
Further, the coin transport device 100 has a coin slot 30h at the center, covers a part of the upper opening of the cylindrical portion 10 in the closed state, and is cylindrical in the open state as shown in FIGS. An openable / closable lid 30 that completely opens the upper opening of the unit 10 is provided.

Normally, the user uses the coin transport device 100 in which the lid 30 is in a closed state (not shown), and throws the coin C into the slot 30 h of the lid 30.
Further, for maintenance or the like, the user opens the lid 30 and removes the rotor 20 from the cylindrical portion 10 to the state shown in FIG. 2 or attaches the rotor 20 to the cylindrical portion 10 to the state shown in FIG. You can.

A passage P through which coins C pass is formed between the side wall 11 of the cylindrical portion 10, the bottom wall 12 of the cylindrical portion 10, and the rotor 20. That is, the passage P is arranged in an annular shape around the rotor 20.

In addition, the coin C after dropping from the drop hole H is appropriately passed through a coin identifying means (not shown) for identifying the type of the coin C and a coin sorting device (not shown) for sorting the coins C by type. It reaches a coin storage device (not shown) that stores C for each type.

Next, each part which comprises the coin conveying apparatus 100 is demonstrated in detail.

(Cylindrical part 10)
As shown in FIGS. 1 to 3, the cylindrical portion 10 secures a space in which a plurality of coins C can be retained upward in a state where the rotor 20 is housed inside.
The cylindrical portion 10 has a side wall 11 and a bottom wall 12. The bottom wall 12 has a drop hole H at a position between the outer periphery of the rotor 20 and the side wall 11 of the cylindrical portion 10 in plan view. Thereby, the coin C in the passage P moves along the side wall 11 of the cylindrical portion 10 and falls from the dropping hole H when reaching the position of the dropping hole H.
The cylindrical portion 10 has a passage inclined surface 12 a (see FIGS. 11 to 14) that transitions to the side wall 11 on the bottom wall 12. Thereby, the coin C (the coins C1, C2, and C3 in FIG. 3) in the vertical posture in the passage P is dropped into the side wall 11 side of the bottom wall 12, that is, the drop hole H provided below the passage inclined surface 12a. Can guide towards Therefore, the coin C can be reliably dropped from the drop hole H provided in the bottom wall 12.
The cylindrical portion 10 includes a motor (not shown), and has a motor shaft M that protrudes upward from the center of the bottom wall 12 and transmits rotation to the rotor 20. The side wall 11 of the cylindrical portion 10 has a cylindrical shape centered on the axis of the motor shaft M.

(Rotor 20)
FIG. 4 is a perspective view of the rotor 20 as viewed from above. FIG. 5 is a perspective view of the rotor 20 as viewed from below. FIG. 6 is an exploded perspective view of the rotor 20. FIG. 7 is a plan view of the rotor 20. FIG. 8 is a side view of the rotor 20. 9 is a cross-sectional view taken along arrow A in FIG. FIG. 10 is a plan view of the coin transport device 100 in a state where coins C are inserted. 11 is a cross-sectional view taken along arrow B in FIG. 12 is a cross-sectional view taken along arrow F in FIG. 13 is a cross-sectional view taken along arrow D in FIG. 14 is a cross-sectional view taken along arrow E in FIG.

The rotor 20 has a function of maintaining the state in which the coin C inserted from the insertion port 30h is placed on the upper part having a flat surface that is nearly horizontal, and the rotation of the rotor 20 on the coin C placed on the upper part of the rotor 20. The function of guiding the coin C to the passage P by applying centrifugal force, the function of changing the posture of the coin C in contact with the rotor 20, the function of lifting the coin C moving in the passage P, and the coin C in the passage P And a function of guiding to the drop hole H.
Further, as shown in FIG. 10, the rotor 20 rotates in the normal rotation direction a (clockwise in a plan view) at normal time or triggered by the insertion of the coin C from the insertion port 30 h. By this rotation, the rotor 20 can apply a centrifugal force to the coin C or change the posture of the coin C in contact with the rotor 20 through friction at the contact portion with the coin C.

The rotor 20 rotates according to the rotation of a motor shaft M (see FIG. 2) that is an output shaft of a motor (not shown).
As shown in FIG. 6, the rotor 20 includes a rotor main body 21, a cover 22, a knob 23, and a guide portion 24, which are assembled as shown in FIGS. 4 and 5. .
Moreover, the rotor 20 has an engaging portion K (see FIG. 9) that engages with the motor shaft M (see FIG. 2). The rotor 20 may incorporate a transmission device such as a gear that transmits the rotation of the motor shaft M (see FIG. 2) to the rotor 20.

As shown in FIGS. 4 and 9, the rotor 20 has a disk shape whose outer shape gradually increases from the top to the bottom. Since the rotor 20 has a disk shape, the coin C can be held on the upper portion of the rotor 20 for a while, and the centrifugal force acting on the coin C is transferred from the center to the outer periphery even when the rotation speed (rotational speed) of the rotor 20 is the same. It can be enlarged as it becomes.
In addition, since the outer shape of the rotor 20 gradually decreases from the top to the bottom, the posture of the coin C placed on the top of the rotor 20 can be gradually changed from the horizontal posture to the vertical posture. Therefore, the coins C in the passage P can be made relatively sparse without the plurality of coins C flowing into the passage P all at once, and the coins C are competing with each other in the passage P so that they are clogged. Can be suppressed.

Moreover, the rotor 20 has a lifting slope G for lifting the coin C staying in the passage P to the upper part of the rotor 20 on the outer peripheral portion. As shown in FIG. 7, the lifting slope G is formed so as to cut out a part of the outer peripheral portion of the disk-shaped rotating body (three portions equally in the circumferential direction in the present embodiment). As a result, the coin C staying in the passage P is lifted to the upper portion of the rotor 20 again while its posture is changed by the lifting slope G as the rotor 20 rotates. In particular, the coin C sandwiched between the other coins C and the rotor 20 without contacting the bottom wall 12 of the cylindrical portion 10 in the passage P is changed in posture by the lifting slope G as the rotor 20 rotates. Then, the rotor 20 is lifted up. On the other hand, the coin C that is in contact with the bottom wall 12 (the passage inclined surface 12a) of the cylindrical portion 10 in the passage P is lifted by the slope G because the other coins C in the competing relation are lifted. If it reaches the drop hole H provided in, it can fall without being disturbed by other coins C.
Therefore, it can suppress that the coin C competes mutually in the channel | path P, and is jammed. Therefore, even if there is a large amount of coins C to be input in a lump, the coins C can be fed out smoothly, so that the feeding efficiency of the coins C can be improved.

As shown in FIGS. 4, 7 and 8, the rotor body 21 constituting the rotor 20 has a first inclined surface 21 a, a second inclined surface 21 b, a third inclined surface 21 c and a vertical surface on the surface in order from the top. It has a surface 21d.

The first inclined surface 21a is around a hole for engaging the knob 23 at the center of the upper portion of the rotor 20, and is inclined so as to be connected to the inclined surface 23a on the extension of the inclined surface 23a of the knob 23. That is, the inclination angle of the first inclined surface 21a (the angle with respect to the horizontal plane) is substantially the same as the inclination angle of the inclined surface 23a of the knob 23. Thereby, the coin C dropped on the knob 23 from the insertion port 30h above the knob 23 can be smoothly moved to the first inclined surface 21a through the inclined surface 23a.

The second inclined surface 21b is a portion that is located at the upper portion of the rotor 20 and maintains the state where the coin C is placed.
The second inclined surface 21b has a gentle inclination (for example, about 0 ° or more and 10 ° or less) with respect to the horizontal plane, or is a substantially horizontal and flat surface. Thereby, while being able to maintain the coin C on the 2nd inclined surface 21b for a while, the force (the component force of the radial direction of the rotor 20) which pushes the other coin C in the channel | path P side (the outer peripheral side of the rotor 20). ) Is weakened. Therefore, since the coins C in the passage P can be made relatively sparse without the plurality of coins C flowing into the passage P all at once, it is possible to suppress the coins C from competing with each other in the passage P and being jammed.

The second inclined surface 21b may have a flat surface with a small curvature. That is, the second inclined surface 21b may be slightly curved so as to protrude upward.
In other words, the second inclined surface 21b may have a gentle inclination with respect to the horizontal plane, or may be a substantially horizontal flat surface having a small curvature.
As a result, the coins C (the coins C4 and C5 in FIG. 3) placed on the upper portion of the rotor 20 do not come into full contact with the second inclined surface 21b. When the coin C has run out, the coin C staying on the second inclined surface 21b can be smoothly fed into the passage P, and the staying amount of the coin C on the passage P side (the outer periphery side of the rotor 20) can be suppressed.

The third inclined surface 21c is an annular surface between the second inclined surface 21b and the vertical surface 21d, and the posture of the coin C is changed from the horizontal posture on the second inclined surface 21b to the vertical posture on the vertical surface 21d. This is a transition part.
The third inclined surface 21c has a larger inclination angle than the second inclined surface 21b. As a result, the posture of the coin C sliding on the second inclined surface 21b from the center toward the passage P is gradually changed from the horizontal posture on the second inclined surface 21b to the vertical posture on the vertical surface 21d. be able to.

21 d of vertical surfaces comprise the path P (refer FIG. 11) for moving the coin C around the rotor 20, with the side wall 11 and the bottom wall 12 of the cylindrical part 10. As shown in FIG. Since the rotor 20 has the vertical surface 21d on the outer peripheral portion, the posture of the coin C reaching the passage P can be made vertical along the vertical surface 21d. Therefore, the coin C can be smoothly dropped from the drop hole H.

The rotor main body 21 has a recess 21G whose width (dimension in the circumferential direction) increases from the first inclined surface 21a to the second inclined surface 21b as it goes downward. Thereby, the attitude | position of the coin C mounted on the upper part of the rotor 20 can be changed and disturbed, and the clogging of the coin C can be suppressed.

The lifting slope G is a slope formed on the outer peripheral portion of the rotor 20 in order to lift the coin C staying in the passage P to the upper part of the rotor 20.

The lifting slope G is formed to lift the coin C in the state where the upper end is not in contact with the side wall 11 as shown in FIG. Thereby, the coin C (refer FIG. 12) which prevents the coin C (refer FIG. 11) moving toward the fall hole H in the state where the upper end is in contact with the side wall 11 from falling from the drop hole H is prevented. 12, 13, and 14 can be lifted up to the upper portion of the rotor 20 in order, so that the coin C (see FIG. 11) that is not blocked by other coins C can be smoothly dropped. Can be dropped from H.

The lifting slope G is formed from the vertical surface 21d of the rotor 20 to the third inclined surface 21c as shown in FIG. The lifting slope G is formed along a spiral curve centering on the rotation axis of the rotor 20 in plan view. That is, the lifting slope G is formed along a curve that approaches the rotation center of the rotor 20 as the rotor 20 rotates forward. Moreover, the lifting slope G is formed in a three-dimensional manner along a curve that changes spirally from the bottom to the top as the rotor 20 rotates forward. As a result, the coin C placed on the slope G in the passage P passes through the state of the coin C in FIG. 12, the coin C in FIG. 13, and the coin C in FIG. The posture can be gradually changed from the posture to the horizontal posture. Therefore, the coin C (see FIG. 12 to FIG. 14) that prevents the coin C (see FIG. 11) moving toward the drop hole H from dropping from the drop hole H can be lifted to the top of the rotor 20. it can.

The cover 22 constituting the rotor 20 has an annular plate shape in which a hole through which the motor shaft M passes is formed at the center, and is disposed so as to cover the lower portion of the rotor body 21.
The rotor body 21 has a plurality of locking portions 22k that lock the ring-shaped guide portion 24 in the circumferential direction (three in the present embodiment).
As shown in FIGS. 4 to 6, the outer shape of the locking portion 22 k of the rotor body 21 complements the outer shape of the ring-shaped guide portion 24 and has an annular shape. The annular outer diameter is slightly larger than the outer diameter of the vertical surface 21d.

Moreover, the latching | locking part 22k has the protrusion 22p which protrudes outward from the vertical surface 21d. That is, the rotor 20 has a protrusion 22p that protrudes outward from the vertical surface 21d of the rotor 20. With such a configuration, since the posture of the coin C in the passage P changes when it touches the protrusion 22p that rotates as the rotor 20 rotates, the clogging of the coin C in the passage P can be eliminated.

The knob 23 that constitutes the rotor 20 has a disk shape that fits into a hole formed in the center of the rotor body 21, has a knob 23 t that protrudes upward in the center, and the rotor body 21 in the lower part. There is provided a locking means that enables the attachment and detachment. Thus, since the knob 23 has the knob 23t, the user can remove the rotor 20 from the cylindrical portion 10 by picking up and lifting the knob 23t, and maintenance of the cylindrical portion 10 including the motor becomes possible. Further, since the knob 23 has a locking means that enables the knob 23 to be attached to and detached from the rotor body 21 below, the knob 23 can be removed from the rotor body 21 and maintenance inside the rotor 20 becomes possible.

As shown in FIG. 6, the guide portion 24 constituting the rotor 20 has a portion (three portions in the present embodiment) that is locked to the locking portion 22 k of the cover 22 recessed inward, and the whole is approximately It is ring-shaped. The guide portion 24 is formed of an elastic body made of a material having a higher friction coefficient than that of the rotor body 21, for example, rubber. Thereby, the coin C reaching the passage P receives the frictional force from the guide portion 24 as the rotor 20 rotates, moves in the passage P, and falls from the drop hole H.
As described above, the rotor 20 includes the ring-shaped guide portion 24 that guides the coin C to the drop hole H at the lower portion. Therefore, the coin C in the passage P can be moved to the drop hole H and dropped.

Here, the vertical distance from the upper surface of the bottom wall 12 of the cylindrical portion 10 to the position of the guide portion 24 is smaller than the radius of the coin C. Thereby, since the position of the center of gravity of the coin C is higher than the position of the guide portion 24 from the upper surface of the bottom wall 12, the posture of the coin C in the passage P can be easily changed. Therefore, it is possible to easily eliminate clogging of coins C.

As mentioned above, although preferable embodiment of this invention was explained in full detail, the coin conveying apparatus 100 which concerns on this invention is not limited to embodiment mentioned above, In the range of the summary of this invention described in the claim Various modifications and changes are possible.

According to the present invention, a coin transport device 100 that feeds out coins C inserted from the upper part to the lower part, the cylindrical part 10 having the side wall 11 and the bottom wall 12, disposed inside the cylindrical part 10, and the cylindrical part And a rotor 20 having a center of rotation 10 as a rotation center, and a passage P through which a coin C passes is formed between the side wall 11, the bottom wall 12, and the rotor 20, and the rotor 20 is formed on the outer periphery of the passage P. Since there is a lifting slope G for lifting the accumulated coin C to the upper part of the rotor 20, even if a large number of coins C having a combination of sizes, weights and shapes are put together in a large amount, the passage P The coins C are sequentially guided to the drop holes H without being clogged, and the accumulated coins C that cause clogging in the passage P are again lifted and returned to the upper portion of the rotor 20. Therefore, it is possible to provide the coin transport device 100 having excellent feeding efficiency.
