2. Description of the Related Art Generally, when coins are inserted into a hopper provided with a feeder section, the inserted coins are arranged in an inclined state with a coin feeding surface on a peripheral side. The coins are sent out of the hopper one by one through the feeder disk. In this case, at the time of coin delivery processing, coins and foreign matter may remain at the bottom of the feeder disc between the disc and the hopper covering the same, so that the coin is prevented from remaining at the bottom of the hopper. An apparatus provided with a processing mechanism is known (for example, Japanese Utility Model Application Laid-Open No. 61-155980). In particular, when handling foreign matter, the foreign matter is dropped and collected into a foreign matter collection box below and removed from the hopper by opening and closing a collection gate provided at the bottom of the hopper.

[0003]

However, when collecting large foreign matter, the large foreign matter is brought into contact with the bottom surface of the lower foreign matter collection box, and the upper part of the large foreign matter is located at the opening / closing position of the collection gate. In some cases, incomplete collection may occur due to obstruction of the closing operation of the collection gate, so that the height direction of the foreign substance collection box needs to be set to be large in accordance with the assumed maximum height of large foreign substances. For this reason, there has been a problem that the size of the foreign substance collection box is increased and the size of the entire apparatus is increased. Therefore, the present invention provides a coin processing apparatus with a foreign substance collection function that can efficiently collect a foreign substance in a foreign substance collection box having a sufficiently small collection space in the height direction by changing the foreign substance collection posture when the foreign substance is dropped and collected. Aim.

[0004]

According to the present invention, coins fed into a hopper are sent out one by one via a feeder disk provided in the hopper, and the coins are sent out. When the foreign matter detection sensor detects foreign matter remaining in the hopper at the time, a coin processing device with a foreign matter collection function that opens and closes a collection gate provided at the bottom of the hopper and drops and collects foreign matter in a foreign matter collection box below the hopper, when the foreign substance collecting a foreign matter collecting acceleration control means for a plurality of times opening and closing the recovered gates, of the foreign matter the feeder disk by forward and reverse rotation operation
Lateral attitude control that converts the recovery attitude from vertical to horizontal
Means .

[0005]

According to the present invention, when the foreign matter is collected, the lateral posture control is performed.
The control means rotates the feeder disk in the normal and reverse directions to apply a lateral force to the foreign matter that is about to fall directly below, thereby changing the collecting posture of the foreign matter from the vertical direction to the horizontal direction, and moving the foreign object downward while lying down In a foreign substance collection box. In addition, the foreign matter collection promotion control means opens and closes the collection gate a plurality of times to promote a lateral collection posture suitable for collecting large foreign matter, and ensures that foreign matter collected below is collected in the foreign matter collection box. To be collected.

[0006]

For this reason, even when collecting large foreign matter, the large foreign matter can be laid horizontally in the foreign matter collection box, and the collection processing can be performed without taking up a long space in the box. Can be. As a result, it is not necessary to provide a large height direction of the foreign substance collection box in correspondence with the assumed maximum height of a large foreign substance. The size of the entire apparatus can be reliably reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawings show a coin processing device with a foreign matter collection function internally provided in the coin processing device. In FIGS.
Various coins of ¥ 10, ¥ 50, ¥ 100, and ¥ 500 1
A feeder unit 12 is provided for transporting the coins 11 one by one in a subsequent stage. The feeder unit 12 drops and supplies coins 11 from an upper coin insertion slot 13 and is inclined at a lower portion communicating with the coins. A feeder disk 14 and a hopper 15 surrounding and covering the inclined outer surface side are provided, and a feeder space 16 for accommodating a large number of coins 11 put in a lump is formed between the two facing portions. . Feeder disk 1 described above
Reference numeral 4 denotes a circumferential groove 17 serving as a feed surface for sinking the coin 11 at a peripheral edge in the upper surface circumferential direction, and is provided at a pitch of a maximum coin diameter in a circumferential direction of the upper surface of the circumferential groove 17 for inclined conveyance. A positioning dog 18 for positioning the coin 11 is formed between the peripheral groove 17 and the two dogs 18, 18 to form a feeder processing unit for scraping up the coin 11 one by one and sending it to the subsequent stage. doing. In this case, the rotation output from the feeder motor M1 is transmitted to the feeder disk 14 via the power transmission mechanism 19, whereby the disk 14 rotates at a reduced speed to a predetermined feed speed. The coins 11 are sent out to the subsequent check section while being sequentially rotated and transferred one by one. In addition, the bottom of the feeder unit 12 has a direct coin tilting mechanism 20 that directly pushes a coin and unlocks the coin in order to eliminate generation of a residual coin due to the catch of the coin, and an indirect mechanism that unlocks the coin in a non-contact manner. Hopper vibration applying mechanism 21 is provided. The coin tilting mechanism 20 that acts directly has a rotation shaft 26 installed at the bottom position of the feeder unit 12 on the side facing the opening window 22 opened at the bottom of the hopper 15, and is linked to one end of the rotation shaft 26. ON / OFF of solenoid 25 connected via piece 27
The turning shaft 26 is turned based on the OFF operation, and the elastic projection 24 fixed to the lower end of the coin defeating piece 23 having the upper end fixed to the turning shaft 26 is allowed to protrude into the above-mentioned opening window 22 to face. ing. When the solenoid 25 is turned on in a state where the elastic projection 24 faces the outside of the hopper, the coin defeating piece 23 tilts. Projecting further inward, the bottom of the hopper 15 and the feeder disk 14
Coin 11 remaining in an upright state along the wall surface between the narrow portions of
To the feeder disk 14 side. Thereby, even if the last one coin remains in the hooked state at the bottom of the feeder unit 12, the coin 11 is properly knocked down and operated to release the jamming phenomenon of the coin. Also,
The indirectly acting hopper vibration imparting mechanism 21 includes a vibration imparting piece 28 having a base end fixed to the above-described rotating shaft 26, and a free end allowed to approach and separate from the bottom outer wall surface of the hopper 15 to face the hopper 15. Is arranged. The vibration applying piece 28 is connected to the solenoid 25
Is turned integrally with a turning shaft 26 which turns based on the ON operation of the hopper 15.
Vigorously abuts the outer surface of the hopper 15 to apply shocking vibration to the hopper 15. Thereby, the hopper 15 and the feeder disk 14
Thus, the locking phenomenon of the coin 11 caught between them is surely avoided. Further, at the bottom of the hopper 15, a collection gate 30 for opening and closing a foreign substance discharge port 29 opened at the bottom of the hopper, and a foreign substance collection box 31 for collecting foreign substances falling from the hopper 15 by opening the gate. And is equipped with. The recovery gate 30 has an upper end pivotally connected to a gate support shaft 32, and the gate support shaft 32 is provided with a lower end portion allowed to tilt about a tilting fulcrum. A link mechanism 33 connected to the lower end portion is driven by a gate motor M2. By doing so, the gate 30
The foreign matter discharge port 29 is provided so as to be openable and closable by moving the lower end portion thereof forward and backward. In the closed position, the urging action of the urging spring 34 attached to the collection gate 30 works to reliably urge and close the foreign matter discharge port 29. A foreign substance collection box 31 is provided below the collection gate 30.
Reference numeral 1 denotes a horizontally elongated box shape having an open upper surface, and is set to be allowed to be pulled out directly below the foreign matter discharge port 29. In this installation space, the height direction of the foreign matter collection box 31 is set as small as possible. I have. For example, as shown in FIG.
The height of the collection box is set to be shorter than the opening width of the foreign matter discharge port 29 opened in a square shape at the center of the bottom surface of the container. The direction corresponds to the forward / reverse rotation direction of the feeder disk 14. This applies a lateral force due to the forward / reverse rotation operation of the feeder disk 14 to the foreign matter which is about to fall directly below the hopper 15 to change the attitude of collecting the foreign matter from the vertical direction to the horizontal direction, thereby causing the foreign matter to lie down. In this state, the foreign matter is collected in the lower foreign matter collection box 31 so that the collection space in the height direction in the box is shortened so that the collection is possible. Further, in this case, if the collection gate 30 is opened and closed a plurality of times, even if the large foreign matter is temporarily sandwiched between the gate portions, the large foreign matter can be reliably tilted, and the horizontal collection posture for the large foreign matter can be efficiently set. It is more effective if the coin tilting mechanism 20 and the hopper vibration imparting mechanism 21 are operated in conjunction with this collection operation. In the figure, S is a residue detection sensor, 35
Is a magnetic magnet, and 36 is a collection box slide rail.

FIG. 4 is a block diagram showing a control circuit of the coin processing apparatus with a foreign matter collecting function. The CPU 41 controls each circuit apparatus according to a program stored in the ROM 42 and stores the control data in the RAM 43 in a readable manner. . CP
As shown in FIG. 5, the feeder motor M1 moves the feeder disk 14 forward and reverse to apply a lateral force to the foreign matter which is going to fall directly below when the foreign matter is collected.
The gate motor M2 is repeatedly output in a forward / reverse direction so as to promote a horizontal collecting posture suitable for collecting large foreign matters by opening / closing the collection gate 30 a plurality of times to output a forward / reverse rotation. Hopper vibration imparting mechanism 21
The solenoid 25 is turned ON repeatedly to output
Turn off. In addition, by taking these output timings efficiently, even if the foreign matter dropped and collected downward is a large foreign matter, the foreign matter can be reliably collected by laying it in the foreign matter collection box 31. The collection processing operation of the coin processing apparatus having the foreign matter collection function configured as described above will be described with reference to the flowchart of FIG. Normally, during the coin processing operation, the feeder disk 14 is driven to rotate based on the processing signal of the coins, and the large number of coins 1 supplied to the feeder unit 12 are supplied.
.. Are sent to the subsequent stage one by one by the sending action of the feeder disk 14 for processing. If the residue detection sensor S does not detect any residue at the time when the coin delivery process is completed, it is determined that a normal coin delivery process has been executed and the coin transaction process is completed (steps n1 to n1). n2).
However, if the residue detection sensor S detects the remaining foreign matter in the hopper 15, the CPU 41 outputs to the feeder motor M1 to continuously rotate the feeder disk 14 forward and reverse to drop the foreign matter falling directly below. Is applied in the horizontal direction to change the attitude of collecting foreign matter from the vertical direction to the horizontal direction. In this state, the foreign matter is output to the gate motor M2, the collection gate 30 is opened for a certain time, and the foreign matter is moved downward. The foreign matter is collected in the foreign matter collection box 31 (steps n3 to n4). At this time,
The CPU 41 outputs to the solenoid 25 to operate the coin tilting mechanism 20 and the hopper vibration applying mechanism 21 continuously,
An external force or vibration is forcibly applied to the foreign matter discharged from the foreign matter discharge port 29 to promote the action of the foreign matter falling by its own weight (step n5). In addition to this, the CPU 41 again operates the gate motor M2 so that large foreign matter can be collected.
And the collection gate 30 is repeatedly opened and closed.
For example, by performing the opening and closing operation twice, even if a large foreign substance is temporarily caught in the gate portion, the opening / closing action can be repeatedly received and the tilt can be surely caused. The collecting posture is promoted, and the collected foreign matter is reliably collected in the foreign matter collection box 31 in a state of being laid down (step n6). After this foreign matter collecting operation is performed, both the forward / reverse rotation operation of the continuously operating feeder disk 14 and the output operation of the coin tilting mechanism 20 and the hopper vibration applying mechanism 21 are stopped, and the collecting process is completed. At this time (steps n7 to n8), at this time, if the residue detection sensor S detects and confirms that the foreign matter in the hopper has been completely recovered, the recovery processing is terminated. If remains, the above-described collection processing operation is repeatedly executed. If the collection is not performed even after executing three times, some abnormality has occurred. (Steps n9 to n10).

As described above, even when collecting large foreign matter, it is possible to lay the large foreign matter horizontally in the foreign matter collection box to shorten the height of the collection space in the box and perform the collection processing. Therefore, it is not necessary to provide a large height direction of the foreign substance collection box in correspondence with the assumed maximum height of the large foreign substance. The size of the entire apparatus can be reliably reduced.

In the correspondence between the present invention and the configuration of the above-described embodiment, the foreign matter detection sensor of the present invention corresponds to the residue detection sensor S of the embodiment. Although corresponding to the CPU 41, the present invention is not limited to only the configuration of the above-described embodiment.
