Description

Detailed Description of the Invention "Industrial Application Field" This invention relates to a coin feeding device that conveys coins from the bottom to the top of the machine in a coin packaging machine that collects and packages coins of the same denomination. It is.

``Prior art and its problems'' As this type of coin feeding device, there is a conventional coin feeding device shown in Japanese Utility Model Publication No. 11824/1983, which conveys coins received in a lower hopper toward an upper rotating disk by a conveyor. known from.

However, the conveyor installed in this coin supply device is
- Since the coins are conveyed by an endless belt, if a large number of coins are fed onto the endless belt at one time, the load on the endless belt becomes large, resulting in malfunction. Sometimes it happened.

In order to solve this problem, the present applicant proposed a coin feeding device disclosed in Japanese Patent Application Laid-Open No. 63-226024.

This coin feeding device is provided by dividing the above-mentioned endless belt into a horizontal belt and an inclined belt according to the conveyance section, and the load placed on each belt is reduced by these horizontal belts and inclined belts. This prevents these belts from malfunctioning.

However, by dividing the belt into two in this way, a new problem has arisen in which coins remain at the joints of these belts due to coin transfer errors.

The cause of such coin residue is shown in Figure 3 (A
) to FIG. 3(D), the following will be explained in the order shown in (1) to (4). In these figures, numeral 1 is a horizontal belt, numeral 2 is an inclined belt, and numerals 3A and 3B are:
The upper surface of the inclined belt 2 has a fixed mutual interval (usually 50 mm).
The protrusions 4 are disposed at a distance from each other to receive and lock coins conveyed by the horizontal belt 1, and reference numeral 4 is a delivery plate for receiving coins that have fallen into the gap 5 between the horizontal belt 1 and the inclined belt 2. . Also, these Figures 3 (A) to (D)
Here, a state in which a large number of protrusions are successively provided at regular intervals is shown by dashed lines.

(1) As shown in FIG. 3(A), when the coin C conveyed by the horizontal belt l is transferred to the inclined belt 2, the coin C is not stopped by the protrusion 3A, and the coin C
The surface portion C8 of the coin C may come into contact with the protrusion 3A, whereby the coin C may be gradually raised up by the protrusion 3A.

(2) In this state, when the inclined belt 2 and the horizontal belt 1 further move in the direction of the arrow, the lower end C2 of the coin C moves into the horizontal belt 1 as shown in FIG. 3(B). The coin C reaches the left end, and after this, the coin C
It attempts to fall through the gap 5 between the inclined belt 2 and the horizontal belt 1 with the lower end side indicated by 3 facing down.

(3) However, at this time, since the next upper protrusion 3B provided on the inclined belt 2 moves up between the a-oblique belt 2 and the horizontal belt 1 at high speed, the coin C is placed on the delivery plate 4. Before being passed, the receiver collides with the protrusion 3B (see FIG. 3(C)), and the coin C comes into contact with the two belt surfaces of the inclined belt 2 (the surface Cl of the coin C touches the inclined belt 2). Before the coin C contacts the inclined belt 2, the coin C is gradually raised up by the protrusion 3B (see FIG. 3(D)).

In other words, when the -degree coin C is raised up by the protrusions 3A and 3B, the operations shown in FIGS.
and the inclined belt 2.

By the way, in order to solve the above-mentioned problem and ensure that the coin C that stands up is aligned with the belt surface 2A of the inclined belt 2, it is sufficient to reduce the speeds of the horizontal belt 1 and the inclined belt 2, respectively. On the one hand, such a solution leads to the problem of slow coin processing time.

In addition, in the above conventional example, the horizontal belt 11 and the inclined belt 2
, which has a structure in which a gap 5 is formed by a transfer plate 4, but the structure is not limited to such a structure. Even in the case of a coin feeding device having a delivery plate 6 that is tilted to the top, the surface of the coin C will not come into contact with the belt surface 2A of the tilted belt 2, and the coins will stand up and remain as described above.

The present invention has been made in view of the above circumstances, and by considering the relationship between the driving speed of the coin feeding device and the mutual spacing of the protrusions to prevent coins from standing up, it is possible to prevent the coin from standing up while the coin feeding device is being driven at high speed. To provide a coin feeding device capable of efficiently processing coins by maintaining the coins and preventing the coins from standing up.

"Means for Solving the Problem" In order to achieve the above object, the present invention includes a lower hopper provided at the lower part of the machine body into which coins to be processed are input, and a lower hopper in which the coins in the lower hopper are loaded onto the upper surface. and a coin feeding device for transporting coins to a rotating disk provided at the top of the machine,
In a coin packaging machine, the coins put into a rotating disk by the coin feeding device are sent out one by one by the centrifugal force of the rotating disk to be sorted, stacked, and packaged. The top surface is smooth,
A horizontal belt that horizontally conveys coins thrown into the lower hopper; and a horizontal belt that is provided near the horizontal belt on the forward side in the direction of movement of the horizontal belt and that locks the coins that are horizontally conveyed by the horizontal belt. and an inclined belt having a plurality of protrusions that are conveyed upward by the inclined belt; With a locking belt,
They are arranged sequentially along the length of the inclined belt.

"Operation" According to the present invention, coins input from the lower hopper and placed on the horizontal belt are horizontally conveyed to the inclined belt, passed through the receiver, and then stopped by the protrusions of the inclined belt. At the top, it is transported upward toward a rotating disk.

Further, the inclined belt includes a locking band in which a plurality of protrusions are provided at constant intervals, and a non-locking band in which the protrusions are not provided, which are sequentially arranged along the length direction. Because of this, if a mistake is made in passing the coin in the locking belt and the coin becomes unstable, and furthermore, if the coin starts to fall between the horizontal belt and the inclined belt, the non-locking belt will The coin can be received and placed on the non-latching belt of the inclined belt while being in contact with the inclined belt surface.

In other words, after correcting the posture of the coin with the unattached and regular belts, the coin can be locked with the subsequent locking band and transported upward.

"Embodiment" Hereinafter, the configuration of a coin wrapping machine which is an embodiment of the present invention will be described with reference to FIG. 1 and FIGS. 2(A) to 2(D).

First, the overall schematic structure of the coin feeding device will be explained with reference to FIG.
There are an upper hopper and a lower hopper in which coins inputted from the OA/IIA are stored, and the coins in these upper hoppers 10 and 11 are sent to the rotating disk 12 by the coin supply device M (coin supply value [for M (Explained in detail later)
.

The rotating disk 12 rotates in a horizontal plane around a vertical rotation axis, applies centrifugal force to the coins stored in the rotating disk 12, and sends out the coins one by one toward the sorting section 13. It looks like this.

The sorting section 13 includes a primary sorting path 14, which slides the coins discharged from the rotary disk 12 by bringing them into contact with conveyor belts 14A-15A disposed above.
It has a secondary sorting passage 15, and these sorting passages 14 and 15 are equipped with sensors (
line sensor, magnetic sensor, etc.), a coin removal section (as shown) that removes coins other than the set denomination due to the difference in diameter and sends them to the sorting chute 16, a different denomination detection sensor/stopper for removing different denominations (both shown) are sequentially provided along the direction of movement of the coin.

The coins (set denomination coins) that have passed through the coin removal section without being removed are collected in a stacking section 17 in front of the sorting section 13.
It is sent into the bureau and accumulated in a rod shape.

Further, the coins rejected by the coin rejecting section due to the difference in diameter from the set denomination are sent through the sorting chute 16 and sent into the sorting box 18 below. In addition, when distributing coins of different denominations from the sorting chute 16 to the sorting box 18, at the time when the rejected coins are received, a shaker is installed at the bottom of the sorting chute 16 so as to be rotatable about a shaft 19A. The minute gate 19 is rotated clockwise A from the standby position shown in the figure.

In addition, if a different denomination (counterfeit coin, foreign coin, etc.) that has the same outer diameter as the set denomination passes through the coin removal section without being rejected, a foreign coin located downstream of the coin removal section will be removed. The denomination detection sensor detects this and immediately operates the stopper and at the same time stops the driving of the conveyor belts 14A and 15A, thereby preventing the coins of different denominations from falling into the stacking section 17. There is. Furthermore, after the movement of the different denomination coins is stopped by the stopper, the different denomination coins are fed into the different denomination box 20 adjacent to the sorting box 18 through the sorting chute 16. In addition, when discharging coins of different denominations from the sorting chute 16 to the different denomination box 19, the sorting gate 19 is moved to the waiting state shown in FIG. Rotate counterclockwise from position B.

On the other hand, the coins pass through the coin removal section of the foki sorting section 13 and the coins are collected at the stacking section 1.
A predetermined number of coins of the set denomination are placed on the shelves 21A and 2LA of the stacking drums 21 and 21 between which the stacking section 17 is formed. After 50 sheets are stacked, they are placed on a shutter (path shown in the figure) provided directly below the stacking drums 21. The accumulated coins placed on this shutter are passed to a supporting line 22 which is movable up and down below the shutter with the shutter open, and then guided to a packaging section 23 located further below. It is now possible to do so.

This packaging section 23 positions the accumulated coins guided by the support line 22 between the three packaging rollers 23A, 23A, and rotates the packaging rollers 23A. - By feeding the wrapping paper between 23A and the accumulated coins, the wrapping paper is wound around the accumulated coins.

Further, a roll chute 24 is provided below the packaging section 23, and a lift mechanism 25 including a basket 25A is provided at the end of the roll chute 24.

The accumulated coins packaged in the packaging section 23 are transported by a roll chute 24 and a basket 25A, and then transported to a roll box 25 provided at the top of the machine N.
It is designed to be inserted inside.

On the other hand, a guide chute 27 is provided in front of the stacking drums 21 and 21 of the stacking section 17 so as to be freely insertable and removable between the stacking drums 21 and 21.

When the mode is changed from the coin wrapping mode to the bag counting mode, the guide unit 27 is installed between the accumulating drums 2 and 2, whose intervals have been widened to the maximum in advance.
1 and 21, and the sorting section 13
The coins sorted in are guided to a counting chute 28 without being accumulated in the accumulating part 17, and are further bagged into a bag (not shown) attached to the tip of the counting chute 28.

Next, the coin supply device M for conveying coins in the lower hopper 11 or the upper hopper IO to the rotating disk 12 will be explained with reference to FIGS. 1 and 2(A) to 2(D). .

As shown in FIG. 1, this coin feeding device M includes, as shown in FIG. A large number of protrusions 32, 32, etc., which are provided in close proximity to the horizontal belt 30 with a small gap U on the front side in the direction of movement of the horizontal belt 30, and which lock coins transported by the horizontal belt 30 and transport them upward, are arranged at regular intervals. (Usually 50 m
m), and a rotating disk 12 provided below the terminal end 31B of the inclined belt 31 to receive the coins conveyed by the inclined belt 31.
and a delivery belt 33 for transporting the horizontal belt 30 and the inclined belt 31.
A transfer plate 34 is arranged to prevent coins passed between the belts 30 and 31 from falling through the gap U to the bottom surface of the machine body N.

Actually, the inclined belt 31 has the plurality of protrusions 32 and
A locking band 35 in which the projections 32, . . . , . They are arranged sequentially along the length. The non-locking band 36 is constituted by a smooth surface having a length approximately four times (SO mm x 4) the distance between the protrusions 32, 32, . . . .

Further, the inclined bell 1-31 is arranged so as to face an opening 10B formed at the lower part of the upper hopper 10, and is arranged in close proximity to this opening 10B, A coin m inserted into the IO through the input port 10A is received from below, and when the inclined belt 31 and the delivery belt 33 are driven, the coin m is scooped up by the protrusions 32, 32, etc. of the inclined belt 31, They are sequentially conveyed toward the rotating disk 12. In addition, in the coin supply device having the structure in which the bottom surface of the upper hopper 10 is formed by the inclined belt 31, when coins are stored in the upper hopper 10, coins are not stored in the lower hopper 11; When coins are stored in the lower hopper 11, no coins are stored in the upper hopper 10.

Hereinafter, regarding the functions of the locking belt 35 and the non-locking belt 36,
This will be explained with reference to FIGS. 2(A) to 2(D) in correspondence with the explanation of "prior art".
