Description

  The present invention relates to a coin feeding device.

  Electronic devices that handle money, such as POS (Point Of Sales) terminal devices, vending machines, ATMs (Automated Teller Machines), etc., may incorporate a coin feeding device.

  A coin feeding device is a device that separates and feeds one or more coins that are input in a lump in a state where denominations are mixed. The coins fed out from the coin feeding device are subjected to processing such as being stored for each denomination after the authenticity and denomination are determined in an electronic device such as a POS terminal device.

  As means for feeding coins of the coin feeding device one by one, there are means using centrifugal force generated by a disk-shaped turntable in addition to means having a hopper and means having a belt. For example, Patent Documents 1 to 4 disclose coin feeding devices that use centrifugal force generated by a disk-shaped turntable. In addition, as for the coin feeding apparatus disclosed by patent document 1, the feeding direction of each coin is a vertical direction. Therefore, the surface of the turntable is a conical surface so that the coins can stand upright in accordance with the feeding direction.

  By the way, in the coin feeding device using the centrifugal force generated by the turntable, these coins stay on the turntable temporarily or in the long term when the amount of coins to be charged in a lump is large. The coin feeding operation may stagnate. This is because a large amount of coins that have been inserted and stacked on the turntable have a large frictional force between the coins and a frictional force between the stacked lump of coins and the turntable. When these frictional forces are larger than the coin feeding output based on the centrifugal force generated by the turntable, the coins stay on the turntable, and the coin feeding operation stagnates. Further, among the coins staying on the turntable, there can be a coin standing upright. The standing coin is supported by a coin feeding port that is formed so that it can pass through the coins that are lying down one by one, or the coin feeding port is blocked.

  As a measure for preventing such a stagnation of the feeding operation due to the stay of coins, for example, there is a measure for providing a label in the vicinity of the coin slot to alert the thrower of the maximum number of coins that can be thrown together. However, it is not always possible to expect the input person to keep the limit number according to the alert and to count the number of coins inserted.

  Moreover, in order to increase the coin output based on the centrifugal force, it is conceivable to increase the rotational speed of the turntable. However, in order to realize this countermeasure, it is necessary to use a higher-performance electric motor as a drive source for the turntable, resulting in an increase in cost of the coin feeding device and an increase in power consumption. In addition, noise may increase.

  Therefore, an object of the present invention is to provide a coin feeding device that can prevent a stagnation of a feeding operation due to the stay of coins at a low cost.

  Another object of the present invention is to provide an electronic apparatus having the above coin feeding device.

  According to the present invention, there is provided a coin feeding device that separates and feeds one or more coins that are input at a time one by one, and has a cylindrical shape including a bottom portion, an upper portion, and a cylindrical wall portion. A cylindrical container provided with a slot and temporarily storing one or more coins to be collectively fed from the coin slot; and a disk-like shape having an upper plate surface, concentric with the central axis of the cylindrical container A rotating table provided in the cylindrical wall portion and on the bottom portion so as to be rotatable around the rotation axis of the rotating plate, and urging the coins on the upper plate surface toward the cylindrical wall portion by a centrifugal force generated by the rotation; A coin delivery port provided at one location on the cylindrical wall so that coins in a down state coming from the turntable can be passed one by one, and the upper plate surface of the turntable is It is inclined so as to descend from the rotation axis of the turntable toward the outside in the radial direction. Coin feeding device can be obtained.

  According to this invention, the electronic device which has the said coin feeding apparatus is obtained.

  The coin feeding device according to the present invention can prevent the stagnation of the feeding operation due to the stagnation of coins at a low cost.

It is sectional drawing of the principal part of the coin feeding apparatus by embodiment of this invention. It is sectional drawing of the principal part of the coin feeding apparatus by the comparative example of this invention.

  Hereinafter, an embodiment of a coin feeding device according to the present invention will be described with reference to the drawings.

  In the embodiment, the coin feeding device is exemplified by a POS terminal device, in particular, a device built in a settlement device. In the figure, the illustration of the components other than the coin feeding device of the POS terminal device (settlement device) is omitted. Also, all the components of the coin feeding device are not shown, only the parts related to the present invention are shown, and the other parts are not shown.

  In each figure, the code | symbol W shows the width direction of the coin feeding apparatus, the code | symbol H shows the height direction of the coin feeding apparatus, and the code | symbol D has shown the depth direction of the coin feeding apparatus. The extending direction of the central axis of the cylindrical container and the extending direction of the rotating shaft of the turntable, which will be described later, are parallel to the height direction H of the coin feeding device.

  First, as an aid to understanding the present invention, a coin feeding device according to a comparative example will be described.

  Referring to FIG. 2, the coin feeding device according to the comparative example has a cylindrical shape including a bottom portion 11, an upper portion 12, and a cylindrical wall portion 13, a coin insertion port is provided in the upper portion 12, and is charged all at once from the coin insertion port. A cylindrical container 10 that temporarily stores one or more coins and a disk-like shape having an upper plate surface 71, and a cylindrical wall portion that is rotatable around a rotation axis X70 that is concentric with the central axis X10 of the cylindrical container 10 10, provided on the bottom 11, and urged from the turntable 70 by a turntable 70 that urges the coin M on the upper plate surface 71 toward the tube wall portion 13 by centrifugal force generated by rotation. Among the plurality of coins M, the coin wall outlet 13 is provided with a coin outlet 131 provided at one location so that the coins in a face-down state can be passed one by one.

  In the coin feeding device according to the comparative example, when the amount of coins M to be input at a time is large, these coins M stay on the turntable 70 temporarily or in a long term, and the coin feeding operation is performed. There is a possibility of stagnation. This is because a large amount of coins M that have been inserted and stacked on the turntable 70 have a large frictional force between the coins and a frictional force between the stacked lump of coins and the turntable 70. When these frictional forces are larger than the coin feeding force based on the centrifugal force generated by the turntable 70, the coin M stays on the turntable, and the feeding operation of the coin M is stagnated. Further, among the coins M retained on the turntable 70, there can be a coin in a standing state (not shown). The standing coins are supported by the coin feeding port 131 formed so as to be able to pass the coins lying down one by one, or the coin feeding port 131 is blocked.

  Next, a coin feeding device according to an embodiment of the present invention will be described.

  Referring to FIG. 1, the coin feeding device according to the embodiment of the present invention includes a cylindrical container 10, a turntable 20, a coin feeding port 131, and a foreign matter discharge port 136, similarly to the coin feeding device according to the comparative example. is doing.

  The cylindrical container 10 has a cylindrical shape including a bottom part 11, an upper part 12, and a cylindrical wall part 13. Accommodate.

  The turntable 20 has a disk shape including a cylindrical container 10 and an upper plate surface 21. The turntable 20 is provided in the cylindrical wall part 10 and on the bottom part 11 so as to be rotatable around a rotation axis X20 concentric with the central axis X10 of the cylindrical container 10. The turntable 20 is driven by an electric motor (not shown) as a drive source. The rotational speed, generated torque, power consumption, and the like of the electric motor may be the same as those of the electric motor for driving the turntable 70 (FIG. 1) of the comparative example. The coin M on the upper plate surface 21 is urged toward the inner surface of the cylindrical wall portion 13 by centrifugal force generated by the rotation of the turntable 20.

  In the present embodiment, the upper plate surface 21 of the turntable is inclined so as to descend from the rotation axis X20 of the turntable toward the outside in the radial direction.

  By comprising in this way, the force of the feeding direction based on the dead weight of the coin M will be added with respect to the feeding output of the coin based on the centrifugal force of the turntable 20. In other words, the coin output is increased. The increased output of coins has a smaller probability than the frictional force between the coins on the upper plate surface 21 and the frictional force between the stacked lump of coins and the turntable 70 as compared with the comparative example. The possibility of staying on the upper plate surface 21 is reduced.

  In the present embodiment, the inclination angle of the upper plate surface 21 with respect to a horizontal plane parallel to the width direction W and the depth direction D is 10 degrees. In the present invention, the inclination angle of the upper plate surface 21 is not limited to 10 degrees, preferably in the range of 5 to 30 degrees, and more preferably in the range of 8 to 20 degrees. In addition, when the inclination | tilt angle of the upper-plate surface 21 is smaller than 5 degree | times, it is thought that the force based on the dead weight of the coin added to the coin output is insufficient. On the other hand, when the inclination angle of the upper plate surface 21 is larger than 30 degrees, it is considered that there is a high possibility that the coin urged by the turntable 20 will stand up.

  The coin delivery port 131 is provided at one location on the cylindrical wall portion 13 so that the coins in a face-down state can be passed one by one among the plurality of coins M urged from the turntable 20. The coin payout opening 131 is inclined so as to descend from the central axis of the cylindrical container toward the outer side in the radial direction. The inclination angle of the coin dispensing opening 131 is the same as the inclination angle of the upper plate surface of the turntable.

  A plurality of foreign matter discharge ports 136 are provided in the cylindrical wall portion 13 so as to allow passage of foreign matters smaller than one coin urged from the turntable 20 (only one location is shown in FIG. 1). The foreign matter discharge port 136 is also inclined so as to descend from the central axis X10 of the cylindrical container 10 toward the outer side in the radial direction. The inclination angle of the foreign matter discharge port 136 is also the same as the inclination angle of the upper plate surface 21 of the turntable 20.

  The foreign matter has entered from the coin slot at the top 12 of the cylindrical container 10. Although not shown in the figure, the plurality of foreign matter discharge ports are configured to join at one place inside the POS terminal device and outside the cylindrical container 10 and to be accumulated at the joining place. The accumulated foreign matter is periodically discarded by a person who maintains the POS terminal device.

  The coin feeding device according to the present invention is not limited to a POS terminal device, but can be applied to electronic devices that handle money such as vending machines and ATMs.
