Since the large-diameter coins are gradually dropped into the sorting holes as the coins are conveyed in the conveying direction by the conveying belt by disposing the coins, it has a problem that the coin passage becomes longer.

Further, in the above-mentioned conventional coin wrapping machine, coins are identified by the coin identification section, but non-wrapped coins of normal coins to be wrapped and non-wrapped normal coins are sent to a coin sorting section having a sorting hole, and coin identification is performed. Since the coins are mechanically sorted only by the diameter of the coins regardless of the discrimination results of the coins, coins having similar diameters, such as coins of 5 yen and 100 yen, are slightly worn or dirty. There is a problem that coins to which coins are attached may be erroneously sorted, and accurate sorting based on the identification result cannot be performed.

[0057] Then, the control unit 95 after the distributing means 26 is actuated by driving the electric motor 35 passes only appropriate coin C ₄ while the non-operating instantly solenoid 56 of the coin blocking means 52, following the coin C When ₅ is identified as normal coins packaged in denomination identification section 48 to stop the passage of the coin C ₅ at the stopper 53, the coin C ₄ guides the coins to the inside than the selection reference position The sorting guide roller 63 located at the second position is guided inward toward the other side of the coin passage 8, the edge of the coin C ₄ falls off the sorting hole 21, and the sorting plate 27 is moved to one side. coin C ₄ so to close the branched chute 23a is open the other branch chute 23b is accommodated in the second housing portion.

When the coin blocking timing sensor 88 detects the normal coin C ₅ to be packed, the control unit 95 operates the coin blocking means 67 to stop the coin C ₅ , and the denomination identifying unit 48 identifies the coin _{5 in the process} of being discriminated. The next coin C _{6 is} also stopped. Electric motor
35 is stopped to stop the transport belts 32 and 38, and the drive stop means 67 is driven to return the sorting guide roller 63 to the first position located on substantially the same plane as the sorting reference position, and the sorting means 26 is also arranged. Perform return operation. Then, the control unit 95 reverses drive the electric motor 35, the coin C ₅ is retracted transferring the coin passage 8 through the denomination identification section 48, the coin C _6, C ₅
Is erased, and the control unit 95 stops the motor 35.

[0059] Then, the control unit 95 is driven to rotate normally electric motor 35, sequentially transferring the coin C _5, C _6, the denomination identification section 48 identifies as a normal coin packaging, coins C _5, as described above, C ₆ is sequentially transferred to the coin accumulation unit 10.

[0060] Further, the denomination identification section 48 is recognized as normal coins of the non-wrapping the next coin C _7, the controller 95 stops driving means
By driving the 67 stepping motor 69, the sorting guide roller 63
From the sorting reference position at the first position to the sorting hole 21 at the second position.
The coin C ₇ is removed from the sorting hole 21 and the denomination identifying unit 48 identifies the next coin C ₈ as a non-wrapped normal coin, and the control unit 95 sets the sorting guide roller 63 to the second coin. Hold it in the state of protruding toward the sorting hole 21 at the position, and move to the next coin C ₈
Is also continuously removed from the sorting hole 21. When the next coin is identified as a normal coin to be wrapped, the control unit 95 drives the stepping motor 69 of the drive stopping means 67 to position the sorting guide roller 63 at the sorting reference position at the second position.

When removing coins from the sorting hole 21,
Since the sorting guide roller 63 protruding into the coin passage 8 is constituted by a rotatable roller member, even if the sorting guide roller 63 is located at each of the first position and the second position, the coin can be smoothly moved. Is not transferred to the coin passage 8 and stays in the coin passage 8.

If the coin removed from the sorting hole 21 is a coin smaller in diameter than the normal coin to be wrapped, the sorting guide roller 63 positioned at the second position for guiding the coin inward from the sorting reference position. The coin is guided inward toward the other side of the coin passage 8, and the coin edge falls off the sorting hole 21.

Further, if the coin removed from the sorting hole 21 is a coin larger in diameter than the normal coin to be wrapped, the sorting guide roller 63 located at the second position for guiding the coin inward from the sorting reference position. The coin is guided inward toward the other side of the coin passage 8, and the coin is guided by the sorting guide roller 63 to transfer the coin from a position lower than the coin passage 8 located at the upstream start end of the movable guide 75. The first that gradually increases in the direction
And the coin is opposite to the coin passage 8 from a position where the height of the vertical portion which is continuous with the first inclined surface portion 80 and contacts the periphery of the downstream coin is equal to or less than the thickness of the coin. Riding on the second inclined surface portion 81 gradually rising toward the outside of the side. Then, the large-diameter coin not to be wrapped is guided by the guiding edge 83a formed in the concave portion 83 on the inner surface of the coin guide cover 82, and the coin is guided to the sorting hole 21 and the edge of the coin is separated from the sorting hole 21 from the sorting hole 21. To be eliminated.

Then, a predetermined number of coins, for example,
When 50 coins are stacked, the packaging mechanism is activated and the coins are wrapped.

[0065]

According to the first aspect of the present invention, as a result of discrimination by the coin discriminating means, a rotatable sorting guide portion for removing normal coins to be wrapped and unwrapped coins not to be wrapped from the sorting holes.
Even if the material is located at each of the first position for passing coins or the second position for removing coins, the coins are smoothly transported and do not stay in the coin passage, so that coin packaging efficiency can be improved .

Even if the coin removed from the sorting hole is a coin larger in diameter than a normal coin to be wrapped, the large-diameter coin is lower than the coin passage surface located at the upstream start end of the movable guide. From the position, the vehicle rides on the first inclined surface that gradually increases in the direction of coin transport, and the coin continues to the first inclined surface and the height of the vertical portion that contacts the peripheral edge of the downstream coin has the height of the coin. From the height position equal to or less than the thickness, the coin rides on the second inclined surface gradually rising outward on the side opposite to the coin passage, and the edge of the coin comes off from the sorting hole and is more reliably dropped and eliminated.
