Description

  The present invention relates to a coin processing apparatus that feeds and conveys a plurality of coins that are input in a batch.

  A conventional coin processing device includes a coin shooter that is provided so as to be parallel to a coin guide path and communicates a coin to a denominated coin storage unit, and an extrusion pin that pushes the coin from the coin guide path to the coin shooter. It corresponds to the coin shooter when it is transported to the vicinity of the coin shooter communicating with the coin storage part of the corresponding denomination by transporting the coins identified with the denomination by the coin guide path. The coins are stored in the coin storage unit by being pushed down onto the coin shooter by the push pin (see, for example, Patent Document 1).

JP 2006-252357 A (paragraph “0013”, FIG. 1)

  However, in the above-described conventional technique, the coin guide path that extends linearly can be used to stably push the coin into the coin shooter with the extrusion pin. When the present invention is applied to a coin processor that moves coins along the line, there is a problem that it is difficult to position the coin shooter and the coins cannot be dropped stably.

  An object of the present invention is to provide means for solving the above problems.

  In order to solve the above-mentioned problem, the present invention includes a transport mechanism that separates and transports inserted coins one by one and a discrimination unit that discriminates the transported coins, and transports the coins transported by the transport mechanism. A reject coin transport port is formed in the middle of the path, and a normal coin transport port is formed downstream of the reject coin transport port along the coin transport direction, and perpendicular to the coin transport direction above the reject coin transport port. By arranging a guide surface configured to be slidable, and when a coin identified as a reject coin is conveyed by the discrimination means, the guide surface is moved in a direction to retract from the reject coin conveyance port. The reject coin that has been transported is dropped into the reject coin transport port.

  As a result, the present invention provides a reject coin transport port and a normal coin transport port in the middle of the coin transport path even when a coin rotating is applied as a transport mechanism, and the reject coin is transported. When it comes, the guide surface is retracted from above the reject coin transport port, so that the reject coin is dropped to the reject coin transport port, so that the coin can be reliably dropped to a predetermined transport port according to the discrimination result. The effect is obtained.

Here, FIG. 3 is explanatory drawing which shows a reject coin conveyance opening, (a) has shown the mode seen from upper direction, (b) has shown the mode seen from the side.
In FIG. 3, reference numerals 30 a and 30 b denote guide surfaces, which are plate surfaces that cover the reject coin conveyance port 26, and each upper surface is formed to have a height position substantially the same as the conveyance guide bottom surface 16.

Reference numerals 31a and 31b denote support members, which are formed in an L shape, and are rotatably supported by inserting the rotation support shafts 32a and 32b into portions bent to the L shape. One end of the support member 31a Is attached to the guide surface 30a, and one end of the support member 31b is attached to the guide surface 30b.
In addition, a hole through which the shaft 34 is inserted opens at the other end of the support members 31a and 31b.

  Reference numeral 34 denotes a shaft, which is inserted into the hole at the other end of each of the support members 31a and 31b, and attached to the reject coin conveyance port 26 side by a biasing member 35 such as a spring from the side where the guide surfaces 30a and 30b are located. I am receiving power.

  When the shaft 34 is moved toward the reject coin conveyance port 26 by the urging force of the urging member 35, the support members 31a and 31b rotate around the rotation support shafts 32a and 32b in a direction in which the guide surfaces 30a and 30b are separated from each other. As a result, the guide surfaces 30a and 30b are positioned at the open position where the upper portion of the reject coin conveyance port 26 is opened.

Therefore, the conveyance guide bottom surface 16 is partially cut away so as not to come into contact with the guide surfaces 30a and 30b in the range in which the guide surfaces 30a and 30b move.
The support members 31a and 31b have different portions inserted through the shaft 34 in order to prevent them from interfering with each other when they rotate about the rotation fulcrum shafts 32a and 32b. It has become.

  A solenoid 36 includes a plunger 37 whose tip is connected to the shaft 34. The plunger 37 connected to the shaft 34 is drawn into the interior when energized, and is indicated by an arrow in FIG. Thus, the shaft 34 is pulled in the reverse direction of the reject coin conveyance port 26, and the plunger 37 protrudes by the urging member 35 when not energized.

  When the solenoid 36 is energized and the shaft 34 is pulled toward the solenoid 36, the support members 31a and 31b rotate about the rotation support shafts 32a and 32b in the direction in which the guide surfaces 30a and 30b approach each other, and the guide The surfaces 30a and 30b are located at a closed position that covers the upper side of the reject coin conveyance port 26.

  The guide surfaces 30a and 30b, the support members 31a and 31b, the shaft 34, the urging member 35, and the solenoid 36 constitute a lid opening / closing mechanism for the reject coin conveying port 26 of the present invention.

The operation of the above configuration will be described.
When coins are input into the input port 2 a in a lump, they are slid down from the slope of the deposit hopper 2 and accumulated on the rotating disk 3.
When the rotary disk 3 is rotated by driving the feeding motor 6, the coins are moved toward the disk guide member 7 side by the centrifugal force of the rotation and separated one by one by passing through the discharge portion 8 and pushed out to the coin passage 9. To go.

The coin pushed out to the coin passage 9 is nipped between the transport rollers 10 and transported to the transport disk unit 15.
At this time, the position detection sensor 23 is in an OFF state, that is, a state where the coin receiving portion 18 can receive the coins that are transported by directing the transport rotating disk 17 to a place where the shielding member 22 does not block the light of the position detection sensor 23. Keep it.

  As a result, the coins transported from the coin passage 9 to the transport disk unit 15 enter the coin receiving portion 18. When the coin detection sensor 24 detects that the coin has been transported to the transport disk unit 15, the disk rotation motor 20 is driven to rotate the transport rotation disk 17.

  While the transport rotary disk 17 is rotating, when the transported coin is detected by the pre-feed sensor 12, the drive of the disk rotary motor 20 is temporarily stopped at the timing when the position detection sensor 23 is turned off. Drive again after a predetermined time.

  By controlling the rotation of the conveying rotating disk 17 by driving the disk rotating motor 20 as described above, the conveying rotating disk 17 stops at a position where the coin conveyed from the coin passage 9 enters the coin receiving portion 18, After the coin enters, the transport rotating disk 17 rotates and moves the coin until the next coin is transported.

  Coins that move due to the rotation of the transport rotating disk 17 pass through the coin discrimination sensors 25a, 25b, and 25c, acquire various characteristic values of the coins by the coin discrimination sensors 25a, 25b, and 25c, and are illustrated based on the characteristic values. The control unit that does not discriminates the authenticity and denomination of coins.

  When a control unit (not shown) determines that the coin is normal, the solenoid 36 is operated when the coin reaches the reject coin transport port 26 to move the shaft 34 connected to the plunger 37 to the solenoid 36 side. The guide surfaces 30a and 30b are positioned at the closed position, and the coins being conveyed are passed over the guide surfaces 30a and 30b and conveyed to the normal coin conveyance port 27, and dropped from the normal coin conveyance port 27. Not transported to the denomination storage.

  On the other hand, when a control unit (not shown) determines that the coin is a reject coin, the guide surfaces 30a and 30b are positioned in the open position by leaving the solenoid 36 de-energized, and the reject coin that has been conveyed is rejected. It is dropped at the transport port 26, transported to a coin return port (not shown) and returned.

  As described above, in the present embodiment, in the coin processing machine having a mechanism for forcibly transporting coins with the transport rotating disk, a reject coin transport port and a normal coin on the moving path in a state of entering the coin receiving unit. Since the transfer port is provided, the coin can be reliably dropped to either one of the two transfer ports.

  In addition, since the two guide surfaces that serve as the lid of the reject coin transport port are provided and the guide surface is moved in a direction orthogonal to the coin transport direction, the reject coin transport port is opened and closed. It is possible to prevent coins from dropping into the reject coin transport port without applying a load or impact to the transport rotating disk by preventing contact with the transport rotating disk during the opening / closing operation.

  In the first embodiment, the case where the reject coin transport port and the normal coin transport port are provided on the transport guide bottom surface 16 of the transport disk unit 15 has been described as an example, but not limited thereto, instead of the transport disk unit 15. The same effect can be obtained even if a later-described coin path 40 is provided as a transport mechanism, and a reject coin transport port and a normal coin transport port are arranged on the coin transport path by the coin path 40.

Here, it is explanatory drawing which shows the coin processor of the other form of FIG. 4, (a) is a side view, (b) is a top view.
In FIG. 4A, reference numeral 40 denotes a coin passage, which is a part that conveys the coin separated from the discharge unit 8, and is driven by the drive motor 42 shown in FIG. 4B in contact with the upper surface of the coin. A conveyor belt 41 that is transmitted and rotated via a gear train 43, a conveyor surface (conveying path bottom surface) 44 that supports coins from below, and the like.

Therefore, the coins discharged from the discharge unit 8 are sandwiched between the transport belt 41 and the transport surface 44 and are transported by the rotation of the transport belt 41.
Reference numeral 45 denotes a discrimination unit, which has a function of discriminating the authenticity, denomination, etc. of coins arranged and passed through the coin passage 40.

Reference numeral 46 denotes a reject coin conveyance port, which is a hole formed in the conveyance surface 44 downstream of the discrimination unit 45 in the coin conveyance direction, and is attached with a lid opening / closing mechanism having a configuration similar to that of the first embodiment (not shown). The reject coin is dropped by positioning the guide surface of the lid opening / closing mechanism at the open position.
The reject coin that has dropped from the reject coin transport port 46 is transported to a coin return port (not shown) and returned.

  As described above, the same effects as those of the first embodiment can be obtained also in the coin processing machine configured to transport the coins separated one by one by the transport belt.
