Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sorting apparatus for a coin processing machine for sorting only coins of a specific denomination from a large number of coins in which a plurality of denominations are mixed.

[0002]

2. Description of the Related Art As a coin sorting apparatus in a coin processor for sorting only coins of a specific denomination from a large number of coins in which a plurality of denominations to be handled are mixed, for example, Japanese Patent Laid-Open Publication No. Hei 3-5818.
No. 8 is known.

The coin sorting apparatus disclosed in the above publication discloses a coin path (coin transport) for transporting coins fed one by one from a rotating disk of a coin supply device on the upstream side by sandwiching the coins with an upper transport belt. Road). The coin sorting device includes a large-diameter coin removing unit that removes a coin (large coin) having a larger outer diameter than a coin (designated coin) of a denomination to be sorted, and a coin having a smaller outer diameter than the set coin. (Small-diameter coins) are excluded.

The large-diameter coin removing means uses a fixed guide rail provided on one side of a coin passage as a reference for sorting, and conveys coins while abutting the fixed guide rail. When the coin is a large-diameter coin, the large-diameter coin is inclined by riding on a slope of a coin guide block provided on a guide rail opposite to the fixed guide rail in the coin passage. While the large coin is transported in the inclined state and sent to a large coin rejection slot provided in the extension of the transport direction, while the coin is a designated coin or a small coin, it is in the transport path. The designated coins and the like are distributed to a coin path different in direction by 90 degrees from the large-diameter coin outlet by making the coin guide block provided along the curve of the inner wall of the coin guide block, and move to the side where the small-diameter coin removing means exists. It is configured to guide. The small-diameter coin elimination means has a pair of left and right coin guides arranged according to the outer diameter of the set coin, and a small-diameter coin smaller than the designated coin from a hollow portion formed between the coin guides. Only drop it down.

[0005]

The coin sorter in the coin processor disclosed in the above publication has the following problems. That is, the large-diameter coin elimination means is configured to sort the transport direction depending on whether or not the distance from the fixed guide rail forming the coin passage is larger than the outer diameter of the designated coin. Is presupposed to be always conveyed along this fixed guide rail. However, the large-diameter coin elimination means has a configuration in which the coins fed out one by one using the rotation of the rotating disk of the coin supply means on the upstream side are transported while being brought into contact with the fixed guide rail by inertia force. In a plurality of denominations to be handled, that is, a coin passage having a passage width capable of carrying coins having different outer diameters, it is not possible to convey all coins conveyed in the coin passage along the fixed guide rail only by inertial force. If a designated coin or a small-diameter coin is transported away from this fixed guide rail, part of the coin is lifted by the coin guide block of the large-diameter coin elimination means and transported to the large-diameter coin outlet as it is. There was a problem that they were incorrectly sorted.

When the large-diameter coin is removed by the large-diameter coin removing means and conveyed along the fixed guide rail in an inclined state, one of the large-diameter coins is stretched over the coin passage along with the inclination of the large-diameter coin. As a result, the transport belt is also moved upward, and as a result, a state occurs in which the transport belt does not come into contact with coins following the large-diameter coin. In other words, subsequent coins that the transport belt does not contact may be separated from the reference fixed guide rail whose transport direction is not determined, and if the subsequent coin leaving the fixed guide rail is a designated coin or a small-diameter coin, Is lifted on one side by the coin guide block of the large-diameter coin elimination means, and is conveyed to the large-diameter coin discharge port. As a result, there is also a problem that misselection is performed as described above.

Further, when the coin guide block 100 of the large-diameter coin removing means rides one side of the large-diameter coin, the large-diameter coin Cb riding on one side is conveyed as shown by an arrow in FIG. In this case, the coin guide block 10 moves laterally by the distance m due to the inclination.
The corner portion 100a of the coin Cb may bite into the uneven portion 101 formed on the front and back surfaces of the coin Cb. At this time, the fixed guide rail 102 and the corner portion 10 of the coin guide block 100
0a is inserted between the large coin Cb and
As a result, there is also a problem that the conveyance is stopped.

The present invention has been made in view of the above circumstances, and does not allow designated coins or small coins to be conveyed to a large coin removal slot due to erroneous sorting, and does not follow a large coin. Specified coins or small-diameter coins can be prevented from being conveyed away from the fixed guide rails without coming into contact with the conveyor belt.Furthermore, lateral movement of large-diameter coins in the conveyance direction near the coin guide block can be prevented. An object of the present invention is to provide a coin sorting device in a coin processing machine which can be smoothly performed and large-diameter coins are not pinched between a corner of a coin guide block and a fixed guide rail.

[0009]

In order to achieve the above object, according to the present invention, both sides of a coin conveying path having a predetermined inclination angle along a horizontal plane with respect to a coin conveying direction by a conveying belt. The part is constituted by left and right guide rails, and a coin guide block that lifts only one side of a large-diameter coin having a larger diameter than the designated coin is provided on a guide rail of the left and right guide rails that is away from the transport belt. The location of the coin transport path where the coin guide block is provided and the left and right widths thereof are set to be substantially the same as the diameter of the designated currency. According to the invention, since the coin transport path is arranged inclined with respect to the transport belt, coins transported by the transport belt are always guided on the opposite side of the coin transport path on the side where the coin guide block is provided. It is transported while abutting on the rail. In other words, at the upstream position of the coin guide block,
Even if the coin to be conveyed is at any position on the coin conveyance path, the coin is finally conveyed while always abutting on the guide rail opposite to the side where the coin guide block is arranged. Therefore, the width of the coin transport path in which the coin guide block is arranged is set to be substantially the same as the width of the designated coin, and the coin to be transported is any one of the designated coin, the large-diameter coin, and the small-diameter coin. However, among these coins, only large coins run on the coin guide block, and other designated coins and small coins do not run on the coin guide block. As a result, large coins, designated coins, and small coins can be reliably sorted.

[0010] In the invention according to claim 2, the downstream side of the coin conveying path where the coin guide block is provided is formed to be bent in a direction opposite to the inclined direction of the coin conveying path, and
An overhang that has a coin drop hole in the center at the bottom of the coin transport path downstream of the location where the coin guide block exists, and supports left and right side edges of only the designated coin on both sides in an engaged state, respectively. A part is provided.
According to the invention, after the large-diameter coins are sorted by the coin guide block, the width of the coin transport furnace is set to be substantially the same as the diameter of the designated coin, so that the coin transport path in which only the designated coin is bent and formed. Are transported while being bent to the opposite side of the coin guide block along the path, but large-diameter coins and small-diameter coins are directly transported along the transport belt without bending. At this time, one side of the large-diameter coin and the small-diameter coin (specifically, the side opposite to the coin guide block) is not engaged with the projecting portion at the bottom of the coin transport path, and as a result, the coin drops on the coin transport path. Dropped from the hole.

In the invention according to a third aspect, the coin guide block for lifting one side of the large-diameter coin is formed with an inclined surface which descends to a guide rail side opposite to the coin guide block. I have. According to the invention,
Since the coin guide block has an inclined surface in the middle,
The angle between the upper surface and the inclined surface of the coin guide block and the angle between the inclined surface and the inner surface are all obtuse. For this reason, the corners of the coin guide block can be prevented from engaging with the irregularities of the large-diameter coin.

According to a fourth aspect of the present invention, at least an upper part of an inner surface of the guide rail opposite to the coin guide block is formed with an inclined surface which is inclined outward. According to the invention, even when the large-diameter coin is lifted on one side by the coin guide block, the other side surface of the large-diameter coin only leans outward along the inclined portion, and the large-diameter coin has a large diameter. It is possible to eliminate or minimize the movement of the coin in the transverse direction with respect to the transport direction.

According to the fifth aspect of the present invention, the transport belt is divided into a plurality of pieces along the transport direction, and the divided transport belts are provided in the vicinity of the coin transport path near the location where the coin guide block is provided. It is characterized by being arranged in an overlapping state. According to the invention, as one side of the large-diameter coin is lifted by the coin guide block, one of the transport belts is also lifted, but at this time, the other transport belt is moved relative to the one transport belt. Since the edge is cut, it is not lifted following the one conveyor belt. Therefore, the other transport belt keeps transporting the coin while being in contact with the coin following the large-diameter coin.

According to the present invention, a double feed prevention plate is provided on an upper portion of the guide rail opposite to the coin guide block to prevent a subsequent coin from riding on a preceding coin. It is characterized by having. According to the invention, when one side of the large-diameter coin is lifted by the coin guide block, it tends to ride on the preceding designated coin or small-diameter coin, but the subsequent large coin is prevented by the double feed prevention plate. Riding is surely prevented. In this sense, misselection can be prevented.

The sorting section 7 is provided on the downstream side of the coin sorting section 6. For example, in the case of a "packing process" in which designated coins are collected and packed in a predetermined number of sheets, In the case of “counting processing” in which the designated coins are transported to the stacking unit 91 provided at the most downstream position of the transport path 2 and the specified coins are counted and discharged out of the machine after counting, the designated coins are transferred to the coin transport path 2. The distributing unit 7 is driven by a driving mechanism (not shown).

The most downstream position of the coin transport path 2 is set to a passage width capable of transporting all denomination coins to be handled, and is located on both sides of the coin transport path 2 in order to reliably detect the passage of coins fed out of the coin transport path 2. A magnetic sensor 92 for magnetically detecting the passage of a coin is provided.

When coins are accumulated, the accumulated coins are conveyed to a wrapping unit (not shown) and wrapped.

Next, the operation of the coin sorting device in the coin processing machine having the above configuration will be described. When the rotating disk 10 of the coin supply device 1 is rotated in the normal rotation direction, the coins on the rotating disk 10 are fed out to the coin transport path 2 one by one. The coin fed out to the coin transport path 2 moves along the linear transport section 24a, the first bent section 24b, and the inclined section 2 on the coin transport path 2 while the upper surface thereof is pressed by the transport belts 31,.
4c, the second bent portion 24d,...

First, the coin discriminating section 4 judges whether or not the coin conveyed on the linear portion 14a is a coin, its denomination, and counting. That is, the coin conveyed on the linear portion 14a is detected by its magnetic properties by the magnetic sensor 41, the diameter of the coin by the line sensor 42, and the unevenness of the peripheral surface of the coin by the indentation detection sensor 43. Based on these detection results, the authenticity, denomination, and counting of coins are determined. If the coin discriminating unit 4 determines that the coin is not a legitimate coin, the coin is stopped by the coin transport stop unit 5 provided in the first bent portion 24b of the coin transport path 2. That is, when a coin determined to be not a legitimate coin is conveyed on the stopper timing sensor 55, the stopper timing sensor 55 detects that fact, and a stopper driving mechanism (not shown) is activated based on a detection signal at that time. The coins are operated, and the stoppers 53 and 54 are rotated to make a part of the stoppers 53 and 54 project into the coin transport path 2. This makes it possible to forcibly stop a coin determined to be not the regular coin. The stopped coins determined to be non-genuine coins are rotated again by the stoppers 53 and 54 so that only the coins determined to be non-genuine coins are conveyed downstream and the denomination setting drive mechanism is operated. By driving the 67, the sorting hole 65a is set to a size that allows all the coins C to fall, and the coins judged to be non-genuine coins conveyed are dropped from the sorting hole 65a and collected. I have to.

The coin discriminated by the coin discriminating unit 4 as a legitimate coin is conveyed to the coin sorting unit 6 along the coin conveying path 2 as it is. And in this coin sorting section 6,
The designated coins are sorted into large coins Cb having a larger diameter than the designated coins and small coins having a smaller diameter than the designated coins. The sorting method will be described in detail.
4c is inclined with respect to the conveyor belts 31 and 32, the coins conveyed by the conveyor belts 31 and 32 always hit the guide inner wall 61 of the third guide rail 22c at the inclined portion 24c. It is transported while touching. That is, no matter which coin is conveyed at any position in the width direction of the coin conveyance path 2 at the upstream position of the first coin guide block 62, the coin is finally formed on the guide inner wall 61 of the third guide rail 22c. It is always transported while abutting.

Here, the first coin guide block 62
The width dimension of the coin transport path 2 at the portion where the second coin guide block 64 is provided is approximately the same as the diameter of the designated coin in advance by the denomination setting drive mechanism 67 (more precisely, the diameter of the designated coin is smaller than the diameter of the designated coin). Is set to be a slightly larger value). Therefore, even if the coin to be conveyed is any of the designated coin, the large coin Cb, and the small coin, only the large coin out of the coins is the third guide rail. The first coin guide block 62 is placed on the first coin guide block 62 disposed at a position facing the guide inner wall 61 of the second coin 22c (see FIG. 3), and other designated coins and small-diameter coins are placed on the first coin guide block 62. I do not get on.

The denomination setting drive mechanism 67 is driven as follows. That is, when the motor 78 is driven, the rotational force of the motor 78 is applied to the first and second gears 7.
The rotation of the cam 77 is transmitted to the cam 77 via 9, 80. With the rotation of the cam, the second movable member 69 is pressed and moved rightward in FIG. 1 via a roller 76 against a spring material (not shown). Alternatively, conversely, the second movable member 69 is moved leftward in FIG. 1 to a position where the roller 76 contacts the cam 77 by the urging force of the spring. This allows
The width dimension of the coin transport path 2 at the portion where the first coin guide block 62 and the second coin guide block 64 are provided can be set to substantially the same as the diameter of the designated coin. Whether or not the rotational position of the cam 77 at this time is correct is detected by the cam positioning sensor 82.

Thereafter, the coins continue to be transported by the transport belts 31 and 32. At this time, due to the presence of the second bent portion 24d, the coin transport path 2 is swung in a direction opposite to the transport direction by the guide inner wall 61 (rightward in FIGS. 1 and 5) after passing the guide inner wall 61. Therefore, only the designated coins abutting on the guide inner wall 62a of the first coin guide block 62 are swung to the opposite side along the coin transport path 2 while being guided by the guide inner wall 62a. On the other hand, the large-diameter coin Cb and the small-diameter coin are not in contact with the guide inner wall 62a, and are conveyed straight along the conveying belt 32 without being swung to the opposite side.

The designated coin swung to the opposite side is supported on the left and right side edges thereof by the transport bottom 21 and the projecting portions 21a, 65b of the transport bottom member 65, and is placed on the straight portion 24e of the coin transport path 2. Is transported to the downstream side, but the large-diameter coin Cb and the small-diameter coin which are linearly transported without being swung to the opposite side have one side edge deviated from one overhang portion 21a and are no longer supported. As a result, as shown in FIG. 5, it is dropped from the sorting hole 65a.

As described above, in the coin sorting section 6, the inclined portion 24 c of the coin transport path 2 is inclined with respect to the transport belts 31 and 32.
After passing through, since it has swung in the opposite direction to the transport direction by the guide inner wall 61, as a result, the designated coin,
The large-diameter coin Cb and the small-diameter coin can be sorted reliably.

The large-diameter coin Cb and the small-diameter coin dropped into the sorting hole 65a pass through a chute 84 provided below the sorting hole 65a, and are further distributed by a sorting unit (not shown) provided below the sorting hole 65a. It is stored in a collection box for collecting large-diameter coins Cb and small-diameter coins. When a reject coin other than a denomination to be handled falls, the reject coin is stored in a reject box for collecting the reject coin by the distribution unit (not shown). The magnetic properties of the coins passing through the coin sorting unit 6 are detected by the magnetic sensor 83, and it is finally determined whether the coins passing through the coin sorting unit 6 are acceptable coins.

In the coin sorting section 6, the transport belts 31 and 32 are divided into a plurality of pieces along the transport direction, and the divided transport belts 31 and 32 are connected to the first coin guide in the coin transport path 2. Since one of the large-diameter coins Cb is lifted by the first coin guide block 62 because the first coin guide block 62 lifts one side (downstream side) of the conveyor belt, the block is arranged in an overlapping state near the position where the block 62 is provided. 3
2 is lifted, but at this time, the other (upstream) conveyor belt 31 is not lifted following the one conveyor belt 32 because the edge is cut off with respect to the one conveyor belt 32. . For this reason, the other conveyor belt 31 continues to convey the subsequent coin while contacting the coin following the large-diameter coin Cb. By transporting the subsequent coin in the pressed state by the other transport belt 31 in this manner, the subsequent coin is transported to the third guide rail 22 opposite to the side where the first coin guide block 62 is provided.
c can be reliably transported while being in contact with the guide inner wall 61, thereby preventing the coin following the inclined large-diameter coin Cb from being erroneously sorted.

The first coin guide block 62 which lifts one side of the large-diameter coin Cb has an inclined surface 62 which is lowered toward the third guide rail 22c on the opposite side.
c, the angle between the inclined surface 62c and the inclined surface 62b, which is the upper surface of the first coin guide block 62, and the angle between the inclined surface 62c and the guide inner wall 62a are all obtuse. Therefore, as shown in FIG. 6, the corners of the first coin guide block 62 have uneven portions 1 of the large-diameter coin Cb.
01, and prevents the large-diameter coin Cb from being sandwiched between the third guide rail 22c and the guide inner wall 61.

As shown in FIG. 3, an inclined portion 61a which is inclined outward is formed on the upper part of the guide inner wall 61 of the third guide rail 22c opposite to the first coin guide block 62. Therefore, even if the large-diameter coin Cb can be lifted on one side by the first coin guide block 62, the other side surface of the large-diameter coin Cb only leans outward along the inclined portion 61a, The movement of the large-diameter coin Cb in the lateral direction with respect to the transport direction can be completely eliminated or minimized. As described above, the lateral movement of the large-diameter coin can be suppressed, and from this point, the corner of the first coin guide block 62 and the third guide rail 22c are also considered.
Of the large-diameter coin Cb with the guide inner wall 61 can be prevented.

When one of the large-diameter coins Cb is lifted by the first coin guide block 62 and the second transport belt 32 is lifted, the second transport belt 32 is moved to the large-diameter coin Cb. There is a concern that the specified coin to be conveyed cannot be brought into contact with the previously conveyed coin and loses the conveying force, and the preceding specified coin is pushed and conveyed by the subsequent large-diameter coin Cb. However, in the coin sorting device having the above-described configuration, the double feed prevention plate 70 for preventing coins from climbing over coins preceding the coins above the third guide rail 22c opposite to the first coin guide block 62. Is provided, it is possible to reliably prevent the large-diameter coin Cb whose one side has been lifted from riding on the preceding designated coin or small-diameter coin.

Further, since the feed roller 71 is provided on the third guide rail 22c, the large-diameter coin Cb or the small-diameter coin is slightly engaged with the overhang portion 21a of the transport bottom 21 and is erroneously transported as it is. In addition, coins other than those designated can be reliably dropped into the selection hole 65a by the feed roller 71.

The designated coin after passing through the magnetic sensor 83 is sorted by the sorting unit 7. That is, in the case of “packing processing” in which designated coins are accumulated and wrapped in a predetermined number of sheets, the accumulation unit 9 provided at the most downstream position of the coin conveyance path 2
Transport to one side. On the other hand, in the case of “counting processing” in which the designated coins are counted and discharged outside the machine after counting, the designated coins are dropped below the coin transport path 2.

After the coins conveyed to the stacking section 91 are magnetically detected by the magnetic sensor 92 to pass, the coins are transferred to the stacking section 9.
Sent to 1. When a predetermined number of coins are accumulated in the accumulation section 91, the accumulated coins are conveyed to a wrapping section (not shown) and wrapped there.

In the above-described embodiment of the present invention, the coin sorting device is disposed immediately downstream of the coin supply device 1. However, the present invention is not limited to this. The coin sorting device may be arranged, and a plurality of coin sorting devices may be arranged.

[0048]

As is apparent from the above description, according to the first aspect of the present invention, the coin transported by the transport belt is inclined with respect to the transport belt, so that the coin transported by the transport belt is The coin is always transported while abutting the guide rail on the opposite side of the coin transport path from the side on which the coin guide block is provided.Therefore, the width of the coin transport path on which the coin guide block is disposed is substantially equal to the width of the designated coin. Because the coins are set to the same degree, regardless of whether the coins to be conveyed are designated coins, large-diameter coins, or small-diameter coins, only large coins out of those coins run on the coin guide block. As a result, large coins, designated coins, and small coins can be reliably sorted.

According to the second aspect of the present invention, after a large-diameter coin is sorted by the coin guide block, only the designated coin is bent to the opposite side of the coin guide block along the bent coin transport path. However, large-diameter coins and small-diameter coins are conveyed straight along the conveyor belt without being bent, so that one side of the large-diameter coin and small-diameter coin is The coin is no longer engaged with the overhanging portion at the bottom, and is dropped from the coin drop hole of the coin transport path. Sorting of coins larger in diameter and smaller in diameter than the designated coin can be performed in the same place.

According to the third aspect of the present invention, since the inclined surface is formed in the middle of the coin guide block, the angle formed between the upper surface and the inclined surface of the coin guide block and the angle between the inclined surface and the inner surface may be changed. Is also obtuse, so that the corners of the coin guide block can be prevented from engaging with the irregularities of the large-diameter coin.

According to the fourth aspect of the present invention, since at least the upper part of the inner surface of the guide rail on the opposite side facing the coin guide block is formed with an inclined part inclined outward, the large-diameter coin can be used. Even if one side is lifted by the coin guide block, the other side surface of the large-diameter coin only inclines outward along the inclined portion, and the lateral movement of the large-diameter coin in the transport direction is opposite. Can be completely eliminated or minimized.

According to the fifth aspect of the present invention, as one side of the large-diameter coin is lifted by the coin guide block, one of the transport belts is also lifted.
At this time, the other conveyor belt is not lifted following the one conveyor belt because the edge of the other conveyor belt is cut with respect to the one conveyor belt. The coin continues to be conveyed while being in contact with the coin following the diameter coin. Therefore, the coin following the inclined large-diameter coin can be reliably transported by the transport belt while abutting against the guide rail on the side opposite to the side where the coin guide block is provided. Sorting can be prevented beforehand.

According to the sixth aspect of the invention, when one side of the large-diameter coin is lifted by the coin guide block, it tends to ride on the preceding designated coin or the small-diameter coin. This makes it possible to reliably prevent large coins from getting on, and in this sense, misselection can be prevented.
