  However, in the overflow chute employed in the conventional medal throwing device disclosed in Patent Document 1, the guiding portion 108 positioned from the side end to the upstream end is indicated by an oval circle in FIG. 3 is a side view of the overflow chute 106 seen from the inside of the receiving pan 100 in FIG. 3, and FIG. 4 is a cross-sectional view at the upstream end as shown with some medals. Since the upstream end (the same for the side ends) of the portion 108 comes into line contact when the face of the medal C comes into contact, the medals C tend to overlap (bridge).

  Therefore, medals are easy to accumulate, and the medals overlap with the lower flow 110, which is the inclined bottom of the overflow chute 106, making it difficult for the medals to flow into the medal collection box. As shown in the image of FIG. There was a problem that.

  In view of such problems, in Patent Document 2, as shown in a perspective view of the entire medal throwing device in FIG. 6, a V-shaped cut portion 143 is provided at the leading end of the leading portion of the overflow chute 142, and a tray When the inside becomes full with accumulated medals, the medals near the cut-out portion 143 among the accumulated medals are impacted by the medals thrown toward the cut-out portion to prevent the medals from overlapping (bridge). ing.

  However, this overflow chute can be used only for an apparatus having an insertion path that allows a medal to be inserted into the V-shaped cut portion 143 at a pinpoint, and is not versatile. That is, in the medal throwing device in which the inserted medal collides with the overflow chute when the medal inserting position is slightly deviated from the V-shaped cut portion 143, even though the tray is not full, the medal There was a problem that the medal flowed down to the collection box.

  The present invention has been made to solve the above-described conventional problems, and it is an object of the present invention to provide a medal throwing apparatus having an overflow chute that can smoothly and reliably flow down medals exceeding a standard. .

According to the present invention, a medal stored in a storage space surrounded by a wall is supplied to a rotating disk rotatably supported on a base plate disposed below, and a receiving tray stores the medal in excess of a reference in the storage space. In the medal throwing device comprising an overflow chute having an inclined bottom part for guiding the medals to a discharge port formed in the wall part of the storage space and discharging the medal to the outside, the side of the inclined bottom part of the overflow chute has At the end, and the medal holding wall extending upward on the downstream side adjacent to the discharge port, and a guiding portion of the continuous arc-shape to the upstream end portion is formed on the upstream side of the medal retainer wall, the circular arc The medal that comes into contact with the guiding portion of the shape is in a point contact state with the guiding portion of the circular arc shape, thereby solving the above problem.

  In the present invention, the inclined bottom portion may be formed in a V shape in which one side of the cross section is shorter than the medal diameter.

According to the present invention, at the side end of the inclined bottom portion of the overflow chute, the medal pressing wall extending upward on the downstream side close to the discharge port, and the circular arc continuous from the medal pressing wall to the upstream end portion on the upstream side. The medal that is in contact with the arc-shaped guide portion is in a point contact state with the arc-shaped guide portion, so that the medal flows into the inclined bottom portion by the medal presser wall. Since the medal storage amount can be increased and the medal can be prevented from making a line contact with the upstream guiding portion, it is possible to smoothly and surely flow the medal above the reference to the discharge port. I can do it now.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 7 is an external perspective view showing the entirety of the medal throwing apparatus according to one embodiment of the present invention, and FIG. 8 is an exploded perspective view thereof.

  The medal throwing device of the present embodiment is roughly composed of a tray part 10, a base unit part 20 positioned below the tray part 10, and a frame part 30 that supports the whole from below.

  The tray unit 10 includes a tray 11 in which a medal is stored and a supply hole or the like for supplying the medal is formed. In the tray 11, a storage space 12 for storing medals is formed by wall portions 13 surrounding the four sides.

  The base unit portion 20 is disposed below the tray 11 and forms a bottom plate 21 and a rotating disk that is supported on the base plate 21 and that throws out medals taken in the receiving holes as it rotates. 22, a medal guide 23 that guides the circumferential sliding of medals taken in the rotating disk 22 and regulates the interval of the medal payout slot, and a base plate as a driving device that rotationally drives the rotating disk 22 21 is provided with a drive motor 24 attached to the rear surface of 21, a counting device 25 for counting medals thrown out as the rotary disk 22 rotates, a discharge plate 26 for regulating the width in the vicinity of the medal discharge port, and the like.

  Furthermore, the frame unit 30 includes a base frame 31 that holds the base unit unit 20, a tray fixing lever 32 that engages and fixes the tray unit 10, and the like.

  In the medal throwing device of the present embodiment, as shown in FIG. 7, the overflow chute 40 included in the tray part 10 is disposed at a predetermined position of the storage space 12 in the tray 11, and the storage space 12 Is configured to discharge the medal C stored above the reference to the medal recovery box through the discharge port 14.

  Hereinafter, the overflow chute 40 will be described in detail.

  FIG. 9 is a plan view of the tray 10 viewed from above, and FIG. 10 is a cross-sectional view taken along the line A-A of FIG. 10, in order to supply the medal C to the rotating disk 22 on the base plate 21. Further, an inclined surface 15 is formed that is guided from the upstream side on the left side of FIG. 9 (right side of FIG. 10).

  The overflow chute 40 has a flow lower portion (inclined bottom portion) 41 that guides the medal C to the discharge port 14 formed in the downstream side wall portion 13A of the tray 11 and discharges the medal C to the outside. The upstream end portion 41A is disposed above the inclined surface 15 along the side wall portion 13B on the inclined downward side.

  As shown in the enlarged perspective view of the overflow chute 40 as viewed from the downstream side attached to the discharge port 14 in FIG. A medal presser wall 42 is provided to prevent more than necessary medals from flowing into the flow lower portion 41, and extends upward. An arcuate guiding portion 44 that protrudes from the side end (straight portion 43) toward the storage space 12 via a straight portion 43 is provided at the side end of the flow lower portion 41 upstream of the medal presser wall 42. It is continuously formed up to the upstream end 41A.

  Further, the flow lower part 41 which is the inclined bottom part is formed in a substantially V shape in which the length L1 and L2 of each side is shorter than the diameter of the medal C, as shown in FIG.

  In addition, as shown in FIG. 13, the relationship between the tray 11 and the separated overflow chute 40 before engagement is provided such that the overflow chute 40 is spaced from the mounting surface on the mounting surface to be attached to the side wall portion 13B. And two claw-shaped holding parts 47 extending vertically downward (only one is shown in FIG. 11) and in the horizontal direction in the vicinity of each holding part 47 as shown in FIG. An engaging claw portion 48 to be engaged is formed.

  On the other hand, the holding part slide hole 16 is formed through the attachment surface of the corresponding side wall part 13B on the tray 11 side, and the holding part 47 of the overflow chute 40 is inserted there as shown by the arrow in FIG. As shown in FIG. 15, after inserting the clamping part 47 downward, the engaging claw part 48 is engaged with the tray 11 and is prevented from coming off by sliding horizontally as shown in FIG. 7. As shown in FIG. 9, it is fixed in a state of being in close contact with the side wall 13B of the tray 11.

  As described above, the overflow chute 40 in the present embodiment can be easily attached to and removed from the tray 11.

  Further, the flow lower part 41 is inclined at, for example, 20 to 30 ° so that the medal C flows smoothly from the guiding part 44 toward the discharge port 14 where the medal recovery box is placed outside. Further, the continuous arc-shaped curved portion formed in the guiding portion 44 has a tangent to the medal presser wall 42, that is, the side end of the flow lower portion 41, as shown in FIG. 9. The maximum inclination angle intersects at 45 ° or less, for example.

  Further, the straight line portion 43 between the guide portion 44 and the medal presser wall 42 is formed with a length equal to or less than the medal diameter, thereby preventing line contact. However, the straight line portion 43 is not necessarily required.

  The operation of the medal throwing device of the present embodiment having the above configuration will be described.

  A medal C is inserted into a tray through a medal sorter and a medal insertion path from a medal slot installed in a housing (not shown), and the number of inserted coins exceeds the maximum number of trays held by the height of the guide portion 44, that is, When the storage height corresponding to the number is exceeded, the medal C is guided by the guiding portion 44 formed in the continuous arc shape of the overflow chute 40 as shown in FIG. To the collection box.

  At this time, since the guide portion 44 is formed in a continuous arc shape, as shown in FIG. 17 on the side surface portion of the overflow chute 40 and FIG. Since it is in a contact state, the balance is easily lost as shown in FIG.

  Accordingly, as shown in the image of FIG. 19, the unbalanced medal falls in the direction of the storage space 12 of the tray 11 or smoothly flows to the collection box through the flow lower part 41 of the overflow chute 40. .

  Further, since the continuous arc-shaped tangent line is formed so as to intersect with the medal presser wall 42 at 45 ° or less, the medal C is easily guided into the overflow chute 40 as shown in FIG. Accumulation can be prevented.

  Further, since the cross-sectional shape of the flow lower part 41 is formed in a V shape whose one side length is equal to or less than the diameter of the medal, the medal C flowing down cannot make surface contact with the flow lower part 41 as shown in FIG. Therefore, the frictional resistance is hardly received, so that the medal can smoothly flow down to the discharge port 14.

  Further, the overflow chute 40 does not need to be pinpointed as in the case of Patent Document 2, and can prevent the medal from dropping onto the chassis at any position near the guiding portion 44. Therefore, since it can be applied to any medal throwing apparatus, it is excellent in versatility.

  As described above in detail, according to the present embodiment, the following effects can be obtained.

  By forming the medal guiding portion 44 in a continuous arc shape, the medal is point-contacted at this ridgeline, so the balance is lost and it falls in the direction of the tray (storage space 12) or passes through the overflow chute 40 smoothly. To flow into the collection box.

  Further, the medal flows along the guiding portion formed in a continuous arc shape, and its tangent intersects the medal presser wall at approximately 45 ° or less, so the medal invites to the overflow chute 40. In addition, since the lower part 41 has a V-shaped cross-sectional shape whose one side is smaller than the diameter of the medal, the medal does not come into surface contact with the lower part 41, so that it can hardly receive frictional resistance. The medals smoothly flow into the medal collection box, and the medal drop to the housing is improved.

  Due to the effects described above, the invitation of medals is improved, and the medal insertion position is not limited, so that the insertion range can be widened.
