This will be described using a top view.

  As shown in the figure, the sorting opening / closing gate 7 that opens as shown by the arrow F in FIG. 4 based on the discrimination result of the discrimination unit 13 is substantially parallel to the coin storage unit bottom surface 8b as shown by the arrow D. An upper wall guide 11 having a shape in which the interval between the inclined guide 10 for dropping the coins 16 in a state where the coin 16 is dropped and the inclined guide 10 becomes narrower in the downstream direction of conveyance is disposed to face the inclined guide 10.

  And the conveyance downstream side of the inclination guide 10 becomes the shape divided into two forks, in order to suppress the flutter of the coin 16, as will be described in detail later. Further, the coin storage portion wall 12 has an R shape that guides the inertial force of the coin 16 that is pushed and conveyed as indicated by the arrow A by the protruding conveyor belt 5 in the falling direction D of the inclined guide 10 as indicated by the arrow G. The side guide 15 is provided.

  By the way, when paying a coin as a change to a customer, as shown in FIG. 3, the coin 16 stored in the coin storage unit 8 for each denomination is rotationally driven by a drive unit (not shown) as indicated by an arrow E. The sheet is separated one by one by the separation roller 18 and conveyed while counting the number of sheets by a counting unit (not shown), and a desired number of coins are paid out to the coin dispensing port 9.

(Operation)
With the above configuration, the coin depositing and dispensing machine 1 according to the first embodiment operates as follows. This operation will be described in detail with reference to the operation explanatory diagrams of FIGS. 1 to 5 and FIG. First, when the coins 16 received from the customer are inserted into the coin deposit slot 2, the coins 16 are fed one by one by the delivery cam 4 which is fed by the deposit feeding belt 3 as shown by the arrow A in FIG. Carry out to Road 6.

  The coins 16 that are further pushed and conveyed by the protruding conveying belt 5 in the deposit conveying path 6 as indicated by the arrow A are denominated by the discrimination unit 13, and the coins 16 are conveyed to the front of the sorting opening / closing gate 7. Then, the sorting opening / closing gate 7 corresponding to the identified denomination is opened by an actuator or the like (not shown).

  Then, as shown in FIG. 4, the coin 16 is guided by the lower surface of the opened sorting opening / closing gate 7 and starts to fall, and thereafter, the coin 16 is directed toward the coin storage unit wall 12 by the inertial force due to the push conveyance. The movement direction of the coin 16 is changed to the falling direction of the inclined guide 10 by the guide 15 as indicated by an arrow G, and the inclined guide 10 drops in a direction substantially parallel to the coin storage unit bottom surface 8b.

  At this time, in the case of high-speed conveyance with a small amount of friction to shorten the processing time, as shown in FIG. 6, the inertia force Nj is greater than the gravity Wg immediately after leaving the deposit conveyance road surface 14, as shown in FIG. After the contact with the side guide 15, the reaction force Fr from the coin storage wall 12 is received around the contact point, and a rotational force as indicated by an arrow H acts on the coin 16.

  Since the coin 16 that has fallen in such a state is bifurcated on the end side of the inclined guide 10, the coin 16 is supported at two points as shown in the a1 and a2 parts of FIG. Rotation is suppressed.

  Further, since the upper wall guide 11 provided to face the inclined guide 10 has a shape in which the interval with the inclined guide 10 becomes narrower toward the conveyance downstream direction, the rotation range of the coin 16 is gradually narrowed. The coin 16 can be dropped in a state where there is no fluttering of the coin 16 and it is substantially parallel to the inclined guide 10, that is, substantially parallel to the coin storage portion bottom surface 8 b.

(Effect of Example 1)
As described above, according to the coin depositing / dispensing machine of the first embodiment, in the coin depositing / dispensing machine that sorts coins according to money type, guides them with the tilt guide, and stores them in the coin storage unit, the tilt guide is on the downstream side of conveyance. Since the upper wall guide has a shape in which the gap between the inclined guide and the inclined guide becomes narrower toward the conveyance downstream direction facing the inclined guide, the flickering of the coin is suppressed, and the inclined guide is suppressed. It is possible to prevent the coins from staying in the vicinity, reliably store the coins by guiding them substantially in parallel with the bottom surface of the coin storage portion, and improve the storage efficiency.

<< Other modifications >>
