Description

  The present invention accepts a large amount of coins (including coin-shaped medals and similar items, collectively referred to as coins) on a rotating disk and feeds the coins one by one to the coin transport path by centrifugal force. The present invention relates to a coin feeding device.

  As shown in Japanese Patent Laid-Open No. 08-263716, a conventional coin feeding device using a rotating disk includes a hopper 1 that can hold a large amount of coins c, and a rotating disk 2 is disposed below the hopper 1. A circumferential guide portion 3 is disposed on the periphery of the rotating disk 2, and a coin receiving portion 4 is formed by cutting out a part of the circumferential guide portion 3. A coin is received from the coin receiving portion 4. A passage 5 is extended outward. The coin receiving unit 4 is provided with a thickness restricting member 6 and a coin guiding member 7 for restricting the coin c fed from the rotating disk 2 to a further state.

  Between the lower edge of the hopper portion 1 and the upper surface of the rotating disk 2, an interval through which a plurality of coins c can pass is formed, and as the rotating disk 2 rotates, the coins c in the hopper portion 1. Are gradually discharged onto the rotating disk 2.

  The discharged coin c is rotated along the circumferential guide portion 3 by centrifugal force, and is sent to the coin passage 5 when reaching the entrance of the coin passage 5. The coin c that has not been fed into the coin passage 5 makes another round on the rotating disk 2 and is then fed into the coin passage 5 when it reaches the entrance of the coin passage 5.

Of the coins c discharged from the hopper unit 1 onto the rotating disk 2, the coins c discharged at a position far away from the coin receiving unit 4 on the upstream side in the rotation direction reach the coin receiving unit 4. Since there is a distance, they are aligned along the circumferential guide portion 3 and are easily fed out quickly. On the other hand, the coins c discharged at a position immediately upstream of the coin receiving portion 4 are not aligned along the circumferential guide portion 3 until reaching the coin receiving portion 4, but are fed out after at least one more turn.
Japanese Patent Laid-Open No. 08-263716

  However, in the above-described conventional device, the distance between the lower opening periphery of the hopper 1 and the circumferential guide 3 is narrow in the vicinity of the entrance of the coin passage 5. On the other hand, since the distance between the lower edge of the hopper 1 and the upper surface of the rotating disk 2 is constant, coins are discharged from the hopper 1 onto the rotating disk 2 from the entire area around the lower open part of the hopper 1. Done uniformly.

  As a result, in the vicinity of the entrance of the coin passage 5 on the rotating disk 2, the coin c tends to stay, and the rotating disk 2 is inclined due to the weight of the staying coin, and the rotating disk 2 and the rotating disk 2. A gap with the thickness regulating member 6 that regulates the coin c fed out from the top to a further state is widened, so that two sheets are fed out or clogged, and the rotating disk 2 may be locked. The coin c in the vicinity of the entrance is not normally fed out. In addition, when a load is applied and this is released, a loud sound or vibration may be generated, which causes discomfort to surrounding people.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a coin feeding device that suppresses occurrence of stagnation of coins at the entrance of a coin passage, enables smooth feeding, and prevents generation of noise. And

  In order to solve the above problem, a hopper part that is disposed above the rotating disk and holds coins and discharges the coins from the lower opening onto the rotating disk, and a rotating disk that moves the coins outward, A disc guide portion provided along the circumference of the rotating disc, a feeding portion provided by cutting out a part of the disc guide portion and projecting inward (center side) from the circumference; A feeding gate provided in the feeding portion and forming a gate gap; and a coin passage extending outward from the feeding portion, and the rotating disk is supported by a plurality of support members and includes At least one is characterized in that it supports a position facing the feeding gate of the feeding section.

  According to the present invention, the rotating disk is supported by the plurality of support members, and at least one of them supports the position facing the feeding gate of the feeding part. Is inclined, and the gate gap 12 between the feeding gate and the rotating disc that restricts the coins fed out from the rotating disc to a further state does not change. Therefore, smooth feeding at the entrance of the coin passage can be made and generation of noise can be prevented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory view of a coin feeding device using a rotating disk according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA in FIG.
In addition, the same code | symbol is attached | subjected about the element common to each drawing.

  1 and 2, a coin feeding device 100 according to the present embodiment includes a hopper portion 1 that can hold a large amount of coins 2, and the hopper portion 1 is attached to a hopper bracket 6. A rotating disk 4 is disposed below the hopper 1 via an annular restricting member 9, and a disk guide 5 is provided on the periphery of the rotating disk 4. Further, a feeding portion 7 is provided by cutting out a part of the disc guide 5, and a feeding gate 3 for restricting coins to a further state is provided at the entrance of the feeding portion 7 to form a predetermined gate gap 12. Has been. Further, a coin conveyance path 8 is extended in the tangential direction.

  The hopper portion 1 is widely formed at the top, receives and stores a large amount of coins 2 and is gradually squeezed downward, and the coins 2 are moved downward from a lower opening portion 1a formed at the lowermost end. 4. Drain on top. An annular restricting member 9 made of an elastic material (for example, rubber) is attached to the lower opening 1 a of the hopper 1 so that a predetermined gap 10 is formed between the lower edge of the annular restricting member 9 and the upper surface of the rotating disc 4. Yes.

  The rotating disk 4 is formed in a substantially smooth disk shape, the rotation center shaft is connected to a motor of a rotation driving source (not shown), and the lower surface is a support member 14 which is three rotating bearings disposed on the feeding base 11. Is supported by. The periphery is surrounded by a disk guide 5.

  A feeding portion 7 is formed in a part of the disk guide 5, and a coin conveyance path 8 is extended outside the feeding portion 7. A feeding gate 3 is attached to the feeding portion 7 to restrict the coins 2 fed from the rotating disk 4 to a further state. Picker rollers 13 are disposed on the coin carrying path 8, and the coins 2 arranged in a single layer are conveyed in the direction of arrow C. Further, the coin conveyance path 8 is disposed at substantially the same height as the upper surface of the rotating disk 4. Further, at least one of the supporting members 14 that support the rotating disk 4 (three rotating bearings) is disposed at a position facing the feeding gate 3.

  Next, the operation of the coin feeding device 100 having the above configuration will be described.

  A large number of coins 2 are inserted into the hopper 1 from above, and the rotating disk 4 is rotated in the direction of arrow B in FIG. As a result, the coin 2 located in the vicinity of the lower opening 1 a in the hopper 1 is discharged onto the rotating disk 4 from the gap 10 between the lower edge of the annular regulating member 9 and the upper surface of the rotating disk 4.

  And the coin 2 discharged | emitted by the upper surface of the rotation disc 4 rotates along the disc guide 5 with a centrifugal force. When the coins 2 along the disk guide 5 reach the feeding unit 7, the coins 2 are fed from the feeding unit 7 to the coin conveyance path 8 by centrifugal force. Further, the coins 2 that are not along the disk guide 5 when reaching the feeding portion 7 travel on the rotating disk 4 again and are along the disk guide 5 in the meantime. Further, when a plurality of coins 2 that have reached the feeding section 7 along the disc guide 5 are overlapped, only the lowest one is fed out by the feeding gate 3, and the rest remains on the rotating disc 4. It is. The coin 2 sent out to the transport path 8 is transported in the direction of arrow C by the picker roller 13.

  Next, the relationship between the position where the coin 2 is discharged from the annular regulating member 9 onto the rotating disk 4 and the behavior of the coin 2 will be described.

  The coin 2 discharged to the position immediately upstream of the feeding portion 7 has a short distance to reach the feeding portion 7 (distance that travels along the rotation of the rotating disc 4). It is not along the guide 5, and it is rotated at least one more turn.

  On the other hand, the coin 2 discharged at a position away from the feeding unit 7 upstream reaches a feeding unit 7 because the distance to reach the feeding unit 7 (the distance traveled along the rotation of the rotating disc 4) is long. At the time point, it is already along the disc guide 5, and is aligned to one sheet through the feeding gate 3 and sent out to the conveyance path 8.

  Further, even when a plurality of coins 2 are arranged on the rotating disk 4 so that the upper-layer coin 2 is about to strike between the disk guide 5 and the annular regulating member 9, Since the restricting member 9 is made of an elastic material, the annular restricting member 9 is elastically deformed, and the tension is released as the rotating disk 4 rotates.

  Further, the width of the rotating disk is narrowed by the feeding part protruding inward (center side) from the arc of the disk guide 5, and the coin 2 tends to stay in the vicinity of the entrance of the coin carrying path 8. Become. The rotating disk 4 is inclined by the weight of the staying coins, the gate gap 12 between the rotating disk 4 and the feeding gate 3 is widened, two sheets are fed out or clogged, and the rotating disk 4 is likely to be locked.

  In order to prevent this, at least one of the supporting members 14 (three rotating bearings) for supporting the rotating disk 4 is disposed at a position facing the feeding gate 3, so that the rotating disk 4 and the feeding gate 3 are arranged. Thus, the gate gap 12 does not become wider due to the weight of the accumulated coin, and the rotating disk 4 and the coin 2 fed out from the rotating disk 4 can be further restricted. When the gate gap 12 between the rotating disk 4 and the feeding gate 3 is stabilized, the feeding of the coins 2 in the vicinity of the entrance of the coin passage 8 is further aligned and performed normally. Picker rollers 13 are disposed on the coin carrying path 8 to convey the coins 2 arranged in a single layer state in the direction of arrow A.

  According to the coin feeding device of the present invention, the coin 2 stays in the vicinity of the entrance of the coin carrying path 8 projecting inward (center side) from the arc of the disc guide 5, coin heavy running, coin feeding. It is possible to prevent clogging at the gate 3 part, rotation disk lock due to clogging, and loud noise and vibration generated when a load is applied and released.

 As described above, the present invention shows an embodiment in which at least one of the supporting members 14 (three rotating bearings) for supporting the rotating disk 4 is disposed at a position corresponding to the feeding gate 3. Without limitation, if the gate gap 12 between the rotating disk 4 and the feeding gate 3 is stable, the rotating disk 4 may be supported by a plurality of support members in the vicinity of the entrance of the coin carrying path 8.

It is explanatory drawing of the coin feeding apparatus using the rotating disc of embodiment of this invention. It is AA arrow sectional drawing of FIG.
