Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a coin processing machine for depositing coins in financial institutions such as banks, and particularly relates to a coin processing machine having a rotating disk. The present invention relates to a device for removing thick coins, deformed coins, or foreign objects other than coins (collectively referred to as residual foreign objects) that are not sent out from a rotating disk into a coin path in a machine.

(Prior Art) Conventionally, a coin processing machine for depositing coins, etc. supplies coins onto a rotating disk surrounded by a peripheral wall.
It is moved to the periphery by the centrifugal force caused by the rotation of the rotating disk,
A thickness regulating member provided at one location on the peripheral wall at an interval slightly larger than the thickness of one coin sends the coins in a single layer in the thickness direction from the rotating disk to the coin passage, where the coins are identified. Based on the identification results, coins were classified into abnormal and normal coins. Abnormal coins are then rejected as reject coins, and normal coins are sorted by denomination, taken in all denominations at once, or returned.

In addition, if there are coins that are too thick to fit under the thickness regulating member, deformed coins, or foreign objects other than coins among the coins fed onto the rotating disk, such objects will not be accepted as coins. Since it remains on the rotating disk without being sent out to the passage, stop the machine and remove the cover etc. that covers the rotating disk.
It was removed manually.

(Problem that the invention aims to solve) In conventional coin processing machines, in order to remove the residue that remains on the rotating disk without being sent to the coin passage, the machine must be stopped and a cover covering the rotating disk etc. The problem was that the work efficiency was very poor because the parts had to be removed manually.

In particular, if a residual foreign object occurs when a general customer is using an automatic coin deposit machine installed in the unmanned machine corner of a financial institution such as a bank,
Since the customer cannot remove the remaining foreign matter himself, he must call a staff member to remove it.
The work efficiency was very poor and it caused congestion. In addition, since the customer inserts the coins themselves, there is no check to see if the coins are deformed or have foreign objects mixed in. This increases the number of times that foreign objects remain, and each time the coins are This was a fatal flaw for an automatic machine, as it had to be called in to have it removed.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a residual foreign matter removal device for a coin processing machine that automatically detects and eliminates residual matter on a rotating disk.

[Structure of the idea]

(Means for Solving the Problems) The residual foreign matter removing device in the coin processing machine of the present invention uses centrifugal force due to the rotation of the rotating disk 11 to remove coins fed onto the rotating disk 11 surrounded by the peripheral wall 12.

Next, the operation of this embodiment will be explained.

Coins inserted from the coin input port 2 are replenished from the coin discharge section 7 onto the rotating disk 11 by the centrifugal force caused by the rotation of the supply disk 5, and then
The peripheral wall 1 is moved to the peripheral edge by centrifugal force due to the rotation of
Move along 2.

Then, the coins moving along the peripheral wall 12 are made into one layer in the thickness direction by the thickness regulating member 15 at the coin delivery port 13, and sent out from the coin delivery port 14 to the outside. The coins are scraped out into the coin passage 18 by the round belt 24 and conveyed through the coin passage 18.

While being conveyed through the coin passage 18, the coins that are identified by the identification sensor 20 and determined to be normal are conveyed as they are by the round belt 24 and ejected into the normal coin drop port 27 of the coin guide plate 21, and are then When the coin is identified, the passage switching member 29 is rotated and advances onto the coin conveyance path, and the passage switching member 29
The abnormal coin is discharged into the abnormal coin removal port 28 and guided to the reject port 49 through the reject chute 48b, 48a. At this time, the conveyance of the coin following the abnormal coin conveyed through the coin path 18 is temporarily stopped by the stopper 26, and after a predetermined time, the stopper 26 is opened and conveyance and identification are resumed.

In addition, during the identification process of this inserted coin, the blower 5
2, air was supplied from the air outlet 54 toward the top of the rotating disk 11 to form an air curtain, and light foreign objects such as paper scraps were found in the coins supplied onto the rotating disk 11. In such a case, the foreign matter is prevented from entering under the thickness regulating member 15.

Furthermore, the magnet 55 attached to the inner surface of the top lid body 50 is used to prevent metal foreign objects such as paper clips and staples from being mixed into the coins fed onto the rotating disk 11 due to the attraction force of the magnet 55. Foreign matter is absorbed and removed to prevent clogging in the coin passage 18 and misidentification at the time of identification.

When the signal from the identification sensor 20 disappears for a predetermined period of time or more, it is assumed that all the inserted coins have been identified, and the remaining foreign object detection operation is automatically started next.

The rotating disk 11 is rotated forward and backward, and the light emitter/receiver 58 detects any residual foreign matter on the rotating disk 11. If the light emitter/receiver 58 does not detect anything here, residual foreign matter is generated on the rotating disk 11. Since this has not been done, the detection operation is ended. In addition, when a coin with a large thickness, a deformed coin, or a foreign object other than a coin that cannot enter under the thickness regulating member 15 is thrown and remains on the rotating disk 11 without being sent out to the coin passage 18,
When the light emitter/receiver 58 detects a residual foreign substance on the rotating disk 11, the moving means 32 moves the movable wall member 31.
is slid upward to open the opening 30, and at the same time, the rotating disk 11 is reversely rotated, and the remaining foreign matter on the rotating disk 11 is removed from the opening 30 by the centrifugal force caused by the reverse rotation.
It is discharged from the residual foreign matter removal port 47 and guided to the reject port 49 through the reject chute 48a. Then, after a predetermined time or the light emitter/receiver 58
When the remaining foreign matter is no longer detected, the movable wall member 31 is slid downward by the moving means 32 to close the opening 30.
is closed and the rotation of the rotary disk 11 is stopped, thereby ending the detection operation.

Note that the movable wall member 31 that closes and opens the opening 30 may be configured to swing, for example, using the upper end as a fulcrum, and in that case, the moving means 32 drives the movable wall member 31 to swing.

Further, the residual foreign matter removal operation may be automatically started after a predetermined time from the start of the input coin identification processing operation.

[Effect of idea]

According to the present invention, on the rotating disk of the coin processing machine,
Even if a coin with a large thickness, a deformed coin, or a foreign object other than a coin that cannot enter under the thickness regulating member is thrown and remains on the rotating disk without being sent to the coin passage, the remaining foreign object will be automatically detected. Since a part of the peripheral wall of the rotating disk can be opened and residual foreign matter can be removed, it is possible to eliminate the troublesome work of stopping the machine, removing the cover, and having people remove it. In automatic deposit machines, there is no need to call an attendant to remove residual foreign matter, and the machine can fully function as an automatic deposit machine.
