Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

<A> Coin Supply Unit FIG. 1 is a plan view of a coin sorting and accumulating apparatus according to the present invention.
FIG. 2 shows a central sectional view thereof. In the figure, reference numeral 10 denotes a rotating plate on which coin groups of different denominations are placed, and reference numeral 11 denotes a fixed wall erected around the rotating plate 10. A part of the fixed wall 11 is notched to form a discharge port 12. The coin group is a rotary table 10
Is moved toward the fixed wall 11 by the centrifugal force of
Through the rotating disk 10 in the tangential direction.

<B> Coin Transfer Means A carry-out path 13 is formed outside the turntable 10 in a straight line facing the discharge port 12. A pair of guide walls 14 are provided on both sides of the carry-out path 13 so as to face each other. Guide wall 1
The opposing distance of No. 4 is set to a distance that allows the passage of coins having the maximum diameter. In the center of the carry-out path 13, there is an upper feed conveyor 20 for carrying coins horizontally from the turntable 1 and carrying them out.
And a lower feed belt 21 for transferring coins from the end point of the upper feed belt 20. Both of the feed belts 20 and 21 can adopt a narrow endless belt conveyor. The upper feed belt 20 contacts the upper surface of the coin in a horizontal state and transports the coin. The lower feed belt 21 forms a groove in the floor surface constituting the carry-out path 13 and is buried in the groove at the same height as the floor surface. The lower feed belt 21 is set to have a higher feed speed relative to the upper feed belt 20. This is to provide a transfer interval between coins as described later.

<C> Centering mechanism On both sides of the lower feed belt 21 on the starting end side, a correction platen 3 rotating at the same level as the feed belt 21 (or the floor surface).
0 and 30 are provided. The correction plates 30, 30 are constantly rotating toward the center of the carry-out path 13 at the same speed.

<D> Identification means An identification sensor 40 is provided above the lower feed belt 21 in front of the correction boards 30, 30. Identification sensor 40
Is a known sensor for sensing the material and diameter of the coin, and the coin information obtained by the identification sensor 40 is used in coin collection control described later.

<E> Collection means In the present invention, a designated denomination is picked up by a pair of rotating bodies 50, 50, and coins are accumulated above the two rotating bodies 50, 50.
That is, the rotating bodies 50 are arranged on both sides of the lower feed belt 21 in front of the identification sensor 40 with their rotation axes directed in the direction of penetration of the floor surface. One or more spiral blades 51 are formed on the peripheral surface of each rotating body 50. In addition to functioning as a coin accumulator, the spiral blade 51 functions as a part of the carry-out path 13 that allows the passage of coins of all denominations when the rotating body 50 is not rotating. 5
During rotation of 0 serves as a pickup member (sorter) to bring have picking a specific denomination of coins from a plurality of denominations. Therefore, the spiral blade 51 is not limited to a continuous spiral surface, but may be a linear shape in which a rod is spirally wound around a rotation axis. The rotation control of both rotating bodies 50 is performed based on the detection signal of the identification sensor 40 described above. The amount of rotation of the rotating body 50 for collecting one coin is determined by the number of spiral blades 51. For example, when the spiral blade 51 is one, the rotating body 50 rotates in units of 360 degrees, and when the spiral blade 51 is in two, it rotates in units of 180 degrees. More preferably, it is desirable to incline the rotation axis of the rotating body 50 so that the surface of the spiral blade 51 is parallel to the belt surface (floor surface) of the lower feed belt 21.

<F> Stoppers Bifurcated stoppers 60 are provided on both sides of the lower feed belt 21 in front of the rotating bodies 50, 50 so as to be able to move up and down. The raising and lowering of the stopper 60 is controlled based on the detection signal of the identification sensor 40. The stopper 60 will be described in detail with reference to FIG. 3. The lower part of the stopper 60 is connected to a motor 62 via a disk 61. Then, only when the designated coin is detected by the identification sensor 40, the motor 62 makes one rotation in conjunction with this detection signal, thereby causing the stopper 60 to protrude above the surface of the lower feed belt 21 to prevent the designated coin from passing therethrough. Is controlled as follows. The elevating mechanism of the stopper 60 shown in FIG. 3 is an example, and it goes without saying that a known elevating mechanism can be applied. Reference numeral 63 shown in FIG. 3 denotes an auxiliary link mechanism that changes the projecting position of the stopper 60 according to the type of designated coin. In this link mechanism, the middle of the auxiliary link 63 is pivotally supported.
Are connected by a connecting member 64, and an engagement roller 65 below the auxiliary link 60 is in contact with a cam 66. The movement range of the stopper 60 is obtained by the swing amount of the auxiliary link 63 which swings and changes in response to the rotation of the cam 66. The rotation amount of the cam 66 is controlled based on a detection signal of the identification sensor 40.

<G> Means for stacking coins The designated coins are stacked on a pair of rotating bodies 50, 50. A front guide 70 for changing the locking position of coins in accordance with the diameter of the designated coin is disposed in front of each rotating body 50, and a coin guide according to the diameter of the designated coin is provided in the center of the rear of both rotating bodies 50. A rear guide 71 for changing the stop position is provided. The coins are accumulated on the rotating body 50 to a certain height while rising on the peripheral surface of the rotating body 50 while being supported by a total of three points of the guides 70, 70, 71. Therefore, of the entire length of each of the guides 70 and 71, the range extending over the entire length of the rotating body 50 functions as a fall prevention member for the designated coin, and the range extending above the rotating body 50 functions as a stacking member for the designated coins. . Also, as shown in FIG.
The upper and lower portions of the guides 0 and 71 are swingably supported by using a known link mechanism or cam mechanism, and the swing amounts of the guides 70 and 71 are controlled based on a detection signal of the identification sensor 40. You. FIG. 5 shows a case where the guides 70 and 71 change according to the size of the designated coin. A1 and A2 indicated by two-dot chain lines are designated coins having different diameters.

<H> Control Unit The control unit inputs a detection signal of the identification sensor 40 to identify the denomination, and controls the rotation of the rotating body 50 and the elevation of the stopper 60 based on the identification signal. The unit can be a commercially available general-purpose computer.

[0017]

Next, the operation will be described.

<B> Unloading of coins As shown in FIG. 1, a group of coins of different denominations is placed on the turntable 10, and when the turn of the turntable 10 is started, the coins are centrifugally moved to the periphery of the turntable 10. Sent to Each coin is continuously taken off the center of the carry-out path 13 by the upper feed belt 20 arranged in the tangential direction of the discharge port 12. Coins are transferred from the upper feed belt 20 to the lower feed belt 21. Since the transfer speed of the lower belt 21 is set to be higher than that of the upper belt 20, coins placed and transferred on the lower belt 21 are transferred at intervals corresponding to the speed difference between the belts 20 and 21. Further, when the coin passes over the rotating correction plates 30, 30, the mounting position is automatically corrected at the center of the carry-out path 13.

<B> Coin Identification When the coin passing through the correction board 30 passes through the identification sensor 40, the denomination is identified by the identification sensor 40.

<C> In the case of non-designated coins If the coins passing through the identification sensor 40 are other than the designated coins,
No control signal is transmitted from the control unit to the rotating body 50 or the stopper 60. Therefore, the unspecified coin passes through the position of the rotating body 50 and the stopper 60. Unspecified coins are transported to the end of the lower feed belt 21 and collected.

<D> Designated coins If the coins that have passed the identification sensor 40 are designated coins, a pair of rotating coins is prevented while the stopper 60 projects to the carry-out path 13 and momentarily blocks the passage of the designated coins. The bodies 50, 50 rotate to collect the designated coin from the carry-out path 13. Rotating body 5
The rotation start timing of 0 is set at a fixed time after the identification sensor 40 detects the designated coin. This time difference is selected in consideration of the feed speed of the lower feed belt 21 and the distance from the identification sensor 40 to the collection point, and the designated coin is placed on a virtual center line connecting the rotation axes of the two rotating bodies 50, 50 at the collection point. It is set so that the rotators 50, 50 start rotating when they arrive. The lower surface of the collected designated coin is supported by the upper surface of the spiral blade 51, and the peripheral surfaces before and after it are supported by both guides 70 and 71. The coins collected by the spiral spring 51 are transported upward with the rotation of the rotating bodies 50, 50, and are sequentially pushed up above the two rotating bodies 50, 50 to be stacked in a bar shape.

<E> Collection of designated coins When a predetermined number of designated coins have been accumulated in the guides 70, 71 on the rotating bodies 50, 50, the operation of the apparatus is temporarily stopped.
The designated coins in the guides 70 and 71 are collected. The designated coin can be collected by hand or collected by holding the upper and lower sides of a coin bundle with a pair of arms (not shown).
