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. 11824/1982, which conveys coins received in a lower hopper by a conveyor toward a rotating disk above. known from.

However, since the conveyor installed in this coin feeding device is configured to transport coins using a single endless belt, if a large number of coins are sent onto the endless belt at once, In some cases, the load applied to the endless belt increases, resulting in malfunction.

In order to solve this problem, the present applicant has filed Japanese Patent Application No. 63-226024 (Unexamined Japanese Patent Application No.
We proposed a coin feeding device shown in Publication No. 73489).

This coin feeding device uses the aforementioned endless belt,
The belt is divided into a horizontal belt and an inclined belt depending on the conveyance section, and these horizontal belts and inclined belts reduce the load on each belt and prevent malfunction of these belts. There is.

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

The causes of such coin remaining will be explained below in the order shown in (1) to (4) with reference to FIGS. 3A to 3D. In addition, in these figures, numeral 1 is a horizontal belt, numeral 2 is an inclined belt, and numeral 3 is a horizontal belt.
Reference numerals A and 3B denote protrusions arranged at a certain interval (usually 50 mm intervals) on the upper surface of the inclined belt 2 to receive and lock coins conveyed by the horizontal belt 1, and numeral 4 denotes a horizontal belt. 1 and inclined belt 2
This is the delivery board that receives the coins that have fallen between 〓5. Moreover, in these FIGS. 3A to 3D, the state in which a large number of protrusions are successively provided at regular intervals is shown by dashed lines.

(1) As shown in FIG. 3A, when the coin C conveyed by the horizontal belt 1 is delivered to the inclined belt 2, the coin C is not caught by the protrusion 3A, and the coin C is The surface portion _c1 comes into contact with the protrusion 3A, and as a result, the coin C may be gradually raised up by the protrusion 3A.

(2) Then, in this state, the inclined belt 2
As the horizontal belt 1 further advances in the direction of the arrow, the lower end _c2 of the coin C reaches the left end of the horizontal belt 1 in the figure, as shown in FIG. It attempts to fall through the space 5 between the inclined belt 2 and the horizontal belt 1 with its lower end side indicated by c ₂ facing down.

(3) However, at this time, since the next upper protrusion 3B provided on the inclined belt 2 rises between the inclined belt 2 and the horizontal belt 1 at high speed,
Before the coin C is delivered onto the delivery plate 4,
The coin C collides with the protrusion 3B (see FIG. 3C), and the coin C hits the belt surface 2 of the inclined belt 2.
A (the surface part c ₁ of the coin C is on the inclined belt 2
Before the coin C contacts the inclined belt 2, etc.), the coin C is gradually raised up by the protrusion 3B (see FIG. 3D).

That is, once the coin C is erected by the protrusions 3A and 3B, the operations shown in FIGS. It will remain between.

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 has the problem of slowing down the coin processing time.

Although the above conventional example has a structure in which the gap 5 is formed by the horizontal belt 1, the inclined belt 2, and the transfer plate 4, the structure is not limited to this, and there are two points in FIG. 3A. As shown by the chain line, even if the coin feeding device is of the type in which an inclined delivery plate 6 is provided between the horizontal belt 1 and the inclined belt 2, the surface of the coin C is in contact with the belt surface 2A of the inclined belt 2. This will not happen, and the coin 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, the present invention is capable of achieving high-speed driving conditions of the coin feeding device. 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 coins in the lower hopper are placed on the upper surface. and a coin feeding device for transporting coins to a rotating disk provided at the top of the machine, and sending out the coins put into the rotating disk one by one by the centrifugal force of the rotating disk by the coin feeding device, In a coin packaging machine that performs sorting, accumulation, and packaging processing, the coin feeding device is comprised of a horizontal belt whose top surface is smooth and which horizontally conveys coins put into the lower hopper; and the horizontal belt. provided in front of the horizontal belt in the moving direction and in close proximity to the horizontal belt;
A tilted belt having a plurality of protrusions that locks and transports coins horizontally by the horizontal belt and conveys them upward, and a transfer device provided between the horizontal belt and the tilted belt to prevent coins from falling. a locking band in which the plurality of protrusions are provided at regular intervals on the inclined belt, and a non-locking band in which the protrusions are not provided, the length of the inclined belt being They are arranged sequentially along the direction, and further, a protrusion passage portion is formed on the transfer member, through which the protrusion of the inclined belt passes.

"Function" According to the present invention, after the coins inputted from the lower hopper and placed on the horizontal belt are horizontally conveyed and delivered to the inclined belt, the coins are held on the protrusions of the inclined belt. is transported upward toward the 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. Therefore, if a delivery error occurs 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 tilt in the non-locking belt The coin can be received and placed on the non-latching belt of the inclined belt while in contact with the belt surface. In this case, the coins that have fallen between the horizontal belt and the inclined belt are received by the transfer member provided between the horizontal belt and the inclined belt, and as described above, Then, while the surface of the coin is in contact with the non-locking band, it is scraped up by the protrusion of the locking band that passes through the lower part of the transfer member between the protrusions, and is conveyed upward. In other words, after correcting the coin's posture with the non-locking belt,
The coin can be conveyed upward while being locked by a subsequent locking band.

The coins (coins of set denominations) that have passed through the coin removal section without being removed are fed into a stacking section 17 in front of the sorting section 13 and are stacked in a bar shape.

The coins rejected by the coin rejecting unit due to the difference in diameter from the set denomination are sent to the sorting chute 16.
and is fed into the sorting box 18 below. In addition, when sorting coins of different denominations from the sorting chute 16 to the sorting box 18, when the rejected coins are received, a sorting gate is installed at the bottom of the sorting chute 16 so as to be rotatable about a shaft 19A. 19 in the clockwise direction 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 simultaneously stops the driving of the conveyor belts 14A and 15A, thereby preventing the coins of different denominations from falling into the stacking section 17. are doing. Furthermore, after the movement of the different denomination coins is stopped by the stopper,
The coins of different denominations are sent through a sorting chute 16 to a different denomination box 20 adjacent to a sorting box 18. When discharging different denomination coins from the sorting chute 16 to the different denomination box 19, the sorting gate 19 is moved from the standby position shown in FIG. 1 at the time when the different denomination coins are received. counterclockwise B
so that it rotates.

On the other hand, the set denomination coins passed through the coin removal section of the sorting section 13 and sent into the accumulation section 17 are spaced apart from each other according to the denomination, and the accumulation section 17 is formed between them. After a predetermined number of 50 sheets are stacked on the shelves 21A, 21A of the stacking drums 21, 21, they are placed on a shutter (not shown) provided directly below the stacking drums 21, 21. The accumulated coins placed on this shutter are transferred to a supporting rod 22 that 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 becoming more and more like this.

This packaging section 23 includes three packaging rollers 23A,
23A, the accumulated coins guided by the support rod 22 are positioned between the wrapping rollers 23A, 23A, and the accumulated coins are placed between the wrapping rollers 23A, 23A and the accumulated coins. By feeding, 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 bucket 25A is provided at the end of the roll chute 24.

The accumulated coins packaged in the packaging section 23 are transferred to a roll chute 24 and a bucket 25A.
The roll box 26 is placed at the top of the machine body N.

On the other hand, the stacking drums 21, 21 of the stacking section 17
A guide chute 27 is provided in front of the space between the stacking drums 21 and 21 so as to be freely inserted and removed.
This guide chute 27 is arranged between the stacking drums 21, 21 whose interval has been widened to the maximum in advance, when the mode is changed from the coin wrapping mode to the bag picking and counting mode. The coins sorted in the sorting section 13 are guided to the counting chute 28 without being accumulated in the accumulating section 17, and the coins are guided to the counting chute 28.
The bag can be removed from a bag (not shown) attached to the tip of the bag.
