  As shown in FIGS. 1 and 2, the coin sorting device 100 according to the present embodiment is, for example, a coin receiving device (not shown) that sequentially arranges a plurality of types of coins C randomly placed in a line and carries them out. The coin C carried out from the wall is guided from the upstream to the downstream by gravity through the passage portion 10 having the outer wall 11 and the slope surface 12, and the coin C is sorted according to the type, and the different falling positions on the opposite side to the outer wall 11. P is dropped.

  The coin C is used in Japan, and in order from the larger outer diameter, a 500 yen coin C500, a 10 yen coin C10, a 100 yen coin C100, a 5 yen coin C5, a 50 yen coin C50, and 1 yen. There are six types of balls C1. The coins C are, in order from the heaviest, a 500 yen coin C500, a 100 yen coin C100, a 10 yen coin C10, a 50 yen coin C50, a 5 yen coin C5, and a 1 yen coin C1. The coin sorting apparatus 100 according to the present embodiment sorts and sorts the coins C by type mainly using the difference in the outer diameter and weight of the coins C.

(Passage)
The passage portion 10 includes an outer wall 11, a slope surface 12, an inner wall 13, and a protruding portion 14.
The outer wall 11 is provided in an inclined state from the inside toward the outside. Thereby, the coin C which rolls the channel | path part 10 can be guide | induced toward the downstream from the upstream side along the channel | path part 10 in the state inclined toward the outer side from the inner side.

As shown in FIGS. 1 and 12 and the like, the passage portion 10 has an introduction portion 50 into which a coin C is introduced on the upstream side.
The introduction part 50 has a biasing part 51 for stabilizing the behavior of the coin C by biasing the introduced coin C from the upper part toward the lower part.
The inner wall 13 in the introduction part 50 may be set higher than the outer diameter of the coin C so that the coin C whose behavior is unstable does not move inward and fall.

The biasing portion 51 is a seesaw-shaped lever as shown in FIGS. 1, 2, 4 and the like, and the central portion of the lever is freely rotatable about a horizontal rotating shaft attached to the upper portion of the passage portion 10. One end disposed on the upstream side is gently pulled by the tension spring 52, and the other end disposed on the downstream side is biased toward the lower part.
Therefore, even if the coin C introduced into the introduction part 50 hits the outer wall 11, the slope surface 12, or the inner wall 13 of the passage part 10 and flies or jumps and becomes unstable, the urging part 51 causes the lower part to move downward. Therefore, the urging unit 51 absorbs the kinetic energy of the coin C and stabilizes the behavior.
Therefore, speed components other than the speed component along the passage portion 10 in the coin C can be quickly reduced, and the coin C can be guided along the passage portion 10 in a state where the behavior is stable.

  The passage portion 10 has a plurality of protrusions provided on the upper portion at positions where the height from the slope surface 12 gradually decreases along the passage portion 10 according to the outer diameter of the coin C that is different for each type. The unit 14 is provided.

  As shown in FIG. 3, the passage portion 10 has a curved portion 40 that is curved in a curved shape in a plan view on the upstream side from the position where the protruding portion 14 is provided. Since the passage portion 10 has the curved portion 40 in a plan view, the passage portion 10 is disposed so as to surround the drop position P in the plan view, the planar space can be made compact, and the coin sorting device 100 is related. It can be easily incorporated into the device.

Further, as shown in FIG. 3, the curve portion 40 may include a portion bent in a clothoid curve shape that gradually decreases in curvature from the upstream side to the downstream side in plan view.
In this way, by setting the curved portion 40 to be a portion bent into a clothoid curve, the preceding coin C on the downstream side can be accelerated, and the succeeding coin C on the upstream side and the preceding coin C on the downstream side can be accelerated. An interval (pitch) with the coin C can be secured.
Thereby, it can suppress that the coins C before and after colliding or overlapping are originated in that speeds differ for every kind of coin C.
Therefore, even if the coins C flow along the passage portion 10 so as to collapse one after another, the rolling speed of each coin C can be secured high, and the coins C are surely dropped one by one. Since it can be dropped to the position P, the sorting accuracy can be ensured.

Further, the curve portion 40 includes a clearance groove g having a corner portion e formed on the outer wall 11 so that the coin C is in point contact along the curve portion 40.
The corner portion e is continuous along the passage portion 10 at a position where the height from the slope surface 12 is lower than the outer diameter of the one-yen coin C1 having the smallest outer diameter among the plurality of types of coins C. Provided. The escape groove g is formed with a width W.
Thereby, when the coin C rolls while changing the direction along the curved portion 40, the upper part or the lower part of the coin C escapes in the outer wall 11 without the central part in the vertical direction of the coin C contacting the outer wall 11. Since rolling occurs while making point contact with the corner portion e of the groove g, the frictional resistance is reduced. Therefore, the coin C can roll smoothly along the curve portion 40.

Further, the slope surface 12 may include a portion where the gradient gradually changes as it goes from the upstream side to the downstream side.
Thus, the preceding coin C on the downstream side can also be accelerated by changing the slope of the slope surface 12 so that it gradually becomes steeper as it goes from the upstream side to the downstream side. The interval (pitch) between the coin C and the preceding coin C on the downstream side can be secured.
Thereby, it can suppress that the coins C before and after colliding or overlapping are originated in that speeds differ for every kind of coin C.
Therefore, even if the coins C flow along the passage portion 10 so as to collapse one after another, the rolling speed of each coin C can be secured high, and the coins C are surely dropped one by one. Since it can be dropped to the position P, the sorting accuracy can be ensured.

  The slope surface 12 may be inclined so as to descend from the inside toward the outside. Accordingly, the posture of the coin C rolling on the slope surface 12 is inclined from the inside to the outside, and the coin C is urged toward the outer wall 11 from the inside by the gravity acting on the coin C. Since it can, it can suppress that the coin C falls inside.

As shown in FIGS. 1, 2, 3, 5, and 8, the protruding portion 14 is provided on the upper portion of the outer wall 11 so as to protrude inward.
Specifically, as shown in FIG. 4, the passage portion 10 includes a first protrusion 141, a second protrusion 142, a third protrusion 143, and a fourth protrusion 144 in order from upstream to downstream. .
A height h1 from the slope surface 12 to the first protrusion 141, a height h2 from the slope surface 12 to the second protrusion 142, a height h3 from the slope surface 12 to the third protrusion 143, The relationship with the height h4 from the slope surface 12 to the fourth protrusion 144 is h1>h2>h3> h4.

  The height h1 is smaller than the outer diameter of the 500-yen coin C500 and larger than the outer diameter of the 10-yen coin C10, and the height h2 is smaller than the outer diameter of the 10-yen coin C10, The dimension is larger than the outer diameter, the height h3 is smaller than the outer diameter of the 100-yen coin C100, and is larger than the outer diameter of the 5-yen coin C5, and the height h4 is smaller than the outer diameter of the 5-yen coin C5. The size is larger than the outer diameter of the 50-yen coin C50.

Thereby, as shown in FIG. 1, when the coin C guided by the passage portion 10 is a 500-yen coin C500 having the largest outer diameter, the 500-yen coin C500 rolls toward the downstream side of the passage portion 10. As a result, the upper end portion of the 500-yen coin C500 is hooked on the first projecting portion 141 located on the most upstream side, the direction of motion is deflected inward, and it falls toward the drop position P1.
Similarly, in the case of the 10-yen coin C10, the upper end of the 10-yen coin C10 is hooked on the second protrusion 142 on the second upstream side, the movement direction is deflected inward, and it falls toward the drop position P2. To do.
Similarly, in the case of a 100-yen coin C100, the upper end portion of the 100-yen coin C100 is hooked on the third protrusion 143 that is third on the upstream side, the direction of motion is deflected inward, and it falls toward the drop position P3. To do.
Similarly, in the case of the 5-yen coin C5, the upper end of the 5-yen coin C5 is hooked on the fourth protrusion 144 on the most downstream side, the direction of motion is deflected inward, and it falls toward the drop position P4.
Then, in the case of the 50-yen coin C50, it does not hit any of the protrusions 14 of the first protrusion 141 to the fourth protrusion 144, travels straight along the passage portion 10, and falls toward the drop position P5.

  Moreover, the protrusion part 14 has the curved surface which faces an inner side, and as shown in FIG. 3, it arrange | positions so that it may protrude as it goes downstream from the upstream of the channel | path part 10 in planar view. Thereby, when the edge part of the coin C rolling along the channel | path part 10 contacts the curved surface of the protrusion part 14, the direction of the coin C goes to the fall position P from the direction along the channel | path part 10. As shown in FIG. It can be smoothly deflected in the direction and can be quickly and surely dropped to the drop position P.

  As shown in FIG. 8, the passage portion 10 is formed at a height v that is continuous with the passage portion 10 in the lower portion and is provided inside the passage portion 10 so that the coin C can get over and fall to the dropping position P. The inner wall 13 is provided.

  Specifically, the height v of the inner wall 13 is set to be smaller than the radius of the 5-yen coin C5. Thereby, the 5-yen coin C5, which is the smallest type of coin C among the coins C excluding the 1-yen coin C1 and the 50-yen coin C50, can get over the inner wall 13 and fall to the drop position P4.

  In this way, the passage portion 10 is continuous along the passage portion 10 and is provided at the inside of the passage portion 10, and is formed with a height v (see FIG. 8) at which the coin C can get over and fall to the dropping position P. Since the inner wall 13 is provided, when the upper end portion of the coin C is hooked on the protruding portion 14, the upper end portion of the coin C is moved inward by the protruding portion 14 while the lower end portion is restricted from moving inward by the inner wall 13. Moved. In other words, the rotational moment acts reliably on the coin C due to the action of the protrusion 14 and the inner wall 13, and the coin C does not fall in various postures and directions, but uniformly changes the flow direction of the passage portion 10. It falls toward the drop position P while changing its posture so as to rotate to the center. For this reason, the coin C can be dropped to the intended drop position P, and the sorting accuracy is increased.

  And since the inner wall 13 is continuing along the channel | path part 10, even if the edge part of the coin C touches the inner wall 13 when the coin C rolls the channel | path part 10, it does not decelerate greatly. The coin C can be rolled along the passage portion 10 at high speed and smoothly while guiding the rolling direction and path.

(First outlet)
By the way, as shown in FIG. 1, the channel | path part 10 has the 1st blowing part 20 which blows off air toward the inner side from the outer side of the channel | path part 10 in the upstream from the position in which the protrusion part 14 was provided.
Specifically, the first blowing unit 20 is a sirocco fan 21, a duct 22 that guides an airflow generated by the sirocco fan 21, and a blower that is an opening for flowing the airflow from the duct 22 toward the passage unit 10. The outer wall 11 has a gap t (see FIG. 9) through which the outlet 23 and the largest type of coin C (500 yen coin C500) pass, and the outer diameter of the smallest type of coin C (1 yen coin C1). A shield 24 that covers the inside of the upper part from a slightly higher position is provided.

  The blower outlet 23 is comprised from several opening provided so that it might open to the wall surface of the outer wall 11, as shown in FIG.1, FIG5 and FIG.6.

  Moreover, the 1st blowing part 20 controls the blowing output of air so that only the lightest kind of coin C (one-yen coin C1) is dropped inside the passage part 10. That is, the outer diameter of the 50-yen coin C50 is only about 1 mm larger than the outer diameter of the 1-yen coin C1, and the inner side is not covered by the shield 24, but the blowing power blows away the 5-gram 50-yen C50. Rather, it is adjusted and controlled to be sufficient to blow 1 gram of 1-yen coin C1. Then, as shown in FIG. 11, only the 1-yen coin C1 that has rolled can be blown away toward the inside and dropped toward the drop position P0.

  The one-yen coin C1 has the lowest rolling speed and comes into contact with the succeeding coin C having a relatively high rolling speed, causing the following coin C to be decelerated and reducing the high-speed processing of sorting. However, since the 1-yen coin C1 can be removed and sorted by the first blowing unit 20 on the upstream side of the passage unit 10, a large number of coins C including a plurality of types of coins C including the 1-yen coin C1 are interrupted. Even if it rolls along the passage part 10 without, the selection of the coins C can be performed at high speed.

  Since the dust, moisture, etc. adhering to the coin C are peeled off by the first blow-out portion 20, the rolling resistance between the passage portion 10 and the coin C can be reduced, and the deceleration of the coin C when it rolls can be suppressed. The coin C can be sorted at high speed.

(Second outlet)
As shown in FIG. 1 and FIG. 2 and the like, the passage portion 10 uniformly distributes air along the passage portion 10 from the outside to the inside of the passage portion 10 at a position corresponding to the position where the protruding portion 14 is provided. It has the 2nd blowing part 30 which blows off.
Specifically, the second blowing unit 30 guides the sirocco fan 31 and the airflow generated by the sirocco fan 31, and the direction of the airflow from the direction along the passage unit 10 toward the inside from the outside of the passage unit 10. And a duct 32 that is an opening for allowing the air flow from the duct 32 to flow out toward the passage portion 10.
The duct 32 has an opening communicating with the sirocco fan 31 and a portion other than the air outlet 33 provided so as to be substantially orthogonal to the opening so that the flow path of the airflow has substantially the same cross-sectional area along the passage portion 10. It covers something. As described above, the air flow path is formed by the duct 32 and the opening communicating with the sirocco fan 31 and the air outlet 33 are substantially orthogonal to each other. Thus, the pressure is increased uniformly, deflected from the direction along the passage portion 10 toward the inside from the outside of the passage portion 10, and flows out from the outlet 33. Therefore, air can be blown out uniformly along the passage portion 10 from the outside to the inside of the passage portion 10.

The blower outlet 33 is comprised from several opening provided so that it might open to the wall surface of the outer wall 11, as shown in FIG.1 and FIG.8 etc. FIG. The opening of the blower outlet 33 is provided with two or more so that a uniform wind pressure may be obtained along the channel | path part 10. FIG. This wind pressure acts equally on the coins C rolling on the passage portion 10.
As a result, the coin C is allowed to float from the outer wall 11 as if it were an air hockey pack, and is prevented from coming into contact with the outer wall 11, and the frictional resistance with the outer wall 11 is reduced. Can be made. Moreover, if it does in this way, even if it is the coin C from which a kind differs, it will come to roll by the almost same behavior. Therefore, it is possible to reduce the gap between the preceding and following coins C due to the difference in the speed of the coins C, and to collide with each other, and to secure the spacing between the preceding and following coins C. It can be dropped to position P.

  The preferred embodiment of the present invention has been described in detail above. However, the coin sorting device 100 according to the present invention is not limited to the above-described embodiment, and is within the scope of the gist of the present invention described in the claims. Various modifications and changes are possible.

  According to the coin sorting device 100 of the present invention, the height of the passage portion 10 from the slope surface 12 is lowered stepwise in accordance with the outer diameter of the coin C that is different for each type along the passage portion 10. A plurality of projecting portions 14 provided at the positions to be formed, the lower portion being continuous along the passage portion 10, provided on the inner side of the passage portion 10, so that the coin C can get over and fall to the dropping position P Since the inner wall 13 formed with the length v is provided, a plurality of types of coins C can be accurately selected at high speed.
