[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill feeding device in a bill validator unit and a driving method thereof.

[0002]

2. Description of the Related Art Banknotes to be inserted into a banknote dispenser of a coin lending machine or a medal lending machine, which are installed in a plurality of rows in a playground such as a pachinko hall, are disclosed in JP-A-60-106744. As described above, the bills are passed to the bill transporting device that runs through the back of the bill.

Generally, a ball lending machine has a depth of 150 m.
m, the depth of the medal lending machine is about 80 compared to the ball lending machine
~ 100 mm long. However, in the present situation, the bill validator is the same as the ball lending machine and the medal lending machine.
However, since each island has a different island width (usually the distance between the glass surfaces of the pachinko machine and slot machine machine), it merges with the coupling guide as shown in Japanese Patent Application No. 1-146017 proposed by the present applicant. The length will be adjusted by the comb-like connection of the guides. The length of the bill is 15 with a 1000 yen bill
Since the length is 0 mm, there is a limit to the length adjustment by comb-shaped joining of the joining guide and the merging guide from this length, and in the case of a medal lending machine, a bill feeding device with a drive unit having a length of 80 to 100 mm is separately provided. I need. When the bill validator determines that it is a true bill, this bill feeding device continues to rotate normally,
Send the bill to the bill transport device. On the other hand, when the bill validator determines that the bill is a counterfeit bill, the bill validator reverses the roller of the bill validator to return the counterfeit bill. When it is judged as a counterfeit bill,
The tip of the bill has already reached the feeder roller.
Further, the inverted signal cannot be taken out from the bill validator. Goodbye, even if we try to control the forward / reverse rotation of the drive unit of the sending device by providing a bill passage sensor in the sending device, it is difficult to synchronize with the forward / reverse rotation of the bill validator, and the cause of bill damage and jamming. become. Furthermore, when the bill is passing through the bill transport device, particularly when it is passing between the bill prefetch sensor and the merging guide, and when the bill is inserted into the facing bill validator unit, when the sending device sends the bill. , The banknotes are piled up at the merge guide. It is not a problem that the banknotes are conveyed by being piled up in the banknote conveying device, but when they are stored in the stacker at the island edge, the counting of each sheet is hindered. Therefore, when there are banknotes that have passed the banknote pre-reading sensor or banknotes that have been inserted into the facing identification unit, these banknotes must be held by the delivery device until they pass the merge guide.

Some bill validators have a function of holding bills by stopping their rollers.
When the distance to the banknote transport device is long, that is, when the island width is wide, the banknote prefetch sensor must be provided at a position from the merging point to a position corresponding to it. As a result, there are cases in which the bill cannot be accommodated within the length of one bill transporting device, or the next bill cannot be easily inserted into the bill validator. In addition, various lengths of coupling guides are prepared to accommodate narrow islands to wide islands, and continuous variation up to each length is adjusted by comb teeth with the confluence guide. Further, as for the bill feeding device, a plurality of bill feeding devices having different lengths are prepared to cope with a wider island width. It is extremely difficult to set the position of the banknote read-ahead sensor for each case where the island width is continuously changed, from the standpoint of standardization of mounting space parts and inventory control. Therefore, when the bill validator determines that the bill is a counterfeit bill, the present invention can easily return the bill, and when it is determined that the bill is a true bill, a bill feeding device and a driving method thereof in the bill validator unit that can control the timing of sending out. It is intended for the purpose of hearing.

[0005]

In order to achieve the above-mentioned object, the present invention provides a bill feeding device and its driving method in a bill identifying unit as follows. That is, the feeding / conveying roller of the bill feeding device in the bill discriminating device unit for delivering bills interposed between the bill discriminating machine and the bill conveying device is loosely fitted to the drive shaft, and is interlocked with the drive shaft. It is connected to the rotating drive roller by a ratchet mesh, and is usually driven by the drive shaft, and the drive shaft stops when there is a banknote passage signal from the banknote prefetch sensor or a banknote insertion signal from the facing banknote validator unit. When it does, the delivery conveyor roller stops together with the drive roller so that the banknote can be held in a state in which it is not defeated by the conveyance force of the banknote conveyor, and the banknote validator determines that the banknote is a counterfeit note and returns it to the drive roller. The drive roller is urged toward the send-out and transport roller so that the send-out and transport roller can idle by the bill-returning transport force, A bill feeding device in a bill validator unit that is slidably fitted, and transports the bills thrown into the bill validator to a bill transport device installed at a place apart from the exit of the bill validator. In the bill sending device, when the bill is passing through the conveying device, especially when passing between the bill prefetch sensor and the merging guide and when the bill is inserted into the facing bill validator unit, when the bill validator passes the bill. From the above, the drive time of the delivery / conveyance roller is preset according to the length of the coupling guide etc., which is installed according to the island width, and after the elapse of the set time, the delivery / conveyance roller is stopped and the leading edge of the banknote Conveying device A bill feeding in a bill validator unit, which is set and controlled so that bills can be held at a position immediately before entering a conveying belt. A driving method of the device.

[0006]

Operation: At the same time when a bill is inserted into the bill validator, the bill feeding device starts to operate. Then, when the bill validator determines that it is a true bill, when there is neither a bill passing signal from the bill leading edge reading sensor of the bill transport device or a bill insertion signal from the facing bill validator unit, the bill sending device is , Continues to operate and sends out the bills to the merging guide of the bill transporting device. When there is a bill passage signal from the bill pre-reading sensor or a bill insertion signal from the facing bill validator unit, the bill delivery device is stopped and the bill is delivered to the O-ring (19) (1) attached to the transport roller.
9) and the pressing roller (13) are held in a sandwiched state,
Should the tip of the bill be the transport roller of the bill transport device (2)
Even if it reaches (3), it is not drawn in. When the bill validator determines that the bill is a counterfeit bill, the bill validator reverses and tries to return the bill. However, the bill dispenser
Since no signal can be obtained from the bill validator, the normal rotation continues. However, since the feeding / conveying roller (12) and the driving roller (23) are connected to each other by the ratchet teeth, when the bill is pulled back in the returning direction by the reverse rotation of the rollers (9) and (10) of the bill validator, the feeding conveyance is performed. The roller (12) easily reverses while sliding the ratchet teeth to return the bill. And the banknote is an O-ring (19) (1
9) and the pressing roller (13), the drive roller (23) biased by the spring (26) slides on the drive shaft (18), and the ratchet teeth (22) are sent out to convey rollers (12). The feeding and conveying roller (12) rotates in the forward direction by meshing with the ratchet wet tooth (21). As described above, the bills that are inserted into the bill validator and are determined to be genuine bills pass through the rollers (9) and (10), and either the bill passing signal from the look-ahead sensor or the bill deposit signal from the facing bill identifying unit. Roller (12) (13) when there is no slump
Forwards to the merging guide of the banknote conveyor,
When either or both of the bill passage signal and the bill insertion signal are present, the bill is held by the rollers (12) and (13).
In addition, by controlling the drive time of the delivery / conveyance roller of the bill delivery device from the time when the bill passes the rollers (9) and (10) (in this case, a drive stop signal of the bill validator is obtained), the width of the island can be varied. Regardless of the above, the leading edge of the bill can be aligned with the position before entering the transport belt of the bill transport device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below.
The bills inserted by the bill validator (8) of the bill validating unit (7) are identified as shown in FIG. 2, and the rollers () of the bill transporting device (1) are passed through the joining guide (14) and the merging guide (15). 2) (2) and the rollers (3) and (3) are stretched between the conveyor belts (4) and (5), and the bills are conveyed to the stacker (6) and stored, while being sandwiched. In FIG. 2, (1
6) is a bill pre-reading sensor. Further, in FIG. 2, if the length from the rollers (9) (10) of the bill validator (8) to the rollers (2) (3) of the bill transport device (1) is longer than the length of the bill, the bill is not sent. Banknote sending device (1
1) Sending out and conveying roller (12) and pressing roller (1)
There is 3). Further, the delivery / conveyance roller (12) and the pressing roller (13) are required to have the following functions. That is, regarding the case where the bill validator judges true bills, the number of bills in the stacker (6) is counted for each bill, so when the bill enters the stacker (6), the bills must be counted one by one. I have to. Therefore, it is desirable that the banknotes are transported in the banknote transport device (1) without overlapping. Therefore, when receiving a signal of bill insertion into the bill validator unit (7) facing the bill pre-reading sensor (16), the feed-out conveying roller (12) and the pressing roller (1).
The bill is held in 3). In this case, the leading edge of the bill should not be conveyed even if it reaches the rollers (2) and (3). That is, the feeding roller (12) and the pressing roller (13) are fed out with a force that does not lose the conveying force of the rollers (2) and (3).
Must hold banknotes. This allows
The banknotes are placed in the banknote transport device (1) one by one.

Next, when the bill validator is a counterfeit bill, the leading end of the bill protrudes to a position where it is sandwiched between the sending-out conveying roller (12) and the pressing roller (13) and is returned, so that the sending-out conveying roller (12) and the pressing roller. The holding force of (13) must be weaker than the return conveyance force of the rollers (9) and (10). In addition, the feeding / conveying roller (12) and the pressing roller (1
The forward and reverse of the rollers (9) and (10) cannot be linked to 3) because a signal is not sent from the bill validator (8), and the bill validator continues to rotate normally during operation. However, when the rollers (9) and (10) are reversed in the counterfeit bill determination, the bill is pulled in the return direction, and the O-rings (19) and (19) are rubbed by friction as shown in FIG. 1 due to the movement of the bill in the return direction. It rotates in the same direction as bills. The feeding / conveying roller (12) equipped with the O-rings (19, 19) is a driving roller (23).
Since it is connected with the ratchet teeth, when the feeding and conveying roller (12) rotates in the reverse direction, it does not engage with each other and idles. Therefore, when the rollers (9) and (10) are reversely rotated in the counterfeit bill determination, even if the drive roller (23) is normally rotated, the feeding / conveying roller (12) is idle without meshing the ratchet teeth, and the bill is easily returned. It

In this embodiment, the pin is used as the interlocking mechanism between the drive roller (23) and the drive shaft (18), but the pin is not limited to this. For example, the outer surface of the drive shaft (18) and the drive roller (23).
The inner surface of each may be formed in a hexagonal shape or the like and fitted and interlocked. Further, the interlocking mechanism of the coupling (27) may be interlocked with another mechanism. As shown in FIG. 3, the bill sending device (11) as described above is arranged on the bill exit side of the bill validator (8) with respect to the bill validator mounting bracket (30) via the roller mount (17). Install. The bill validating unit (7) can be attached to and detached from the mounting seat (31) by sliding it as shown in FIG. 4, and can be pulled out from the mounting seat (31) when a trouble occurs in the bill feeding device (11). Maintenance can be performed.

The mounting seat (31) is shaped like a case, and is slidably mounted by fitting the guides (31a) (31b) on the upper wall (30a) and the lower wall (30b) of the bill identifying fitting (30). To be And a bill identification attachment (30)
The stopper (33) of the case is engaged with the engaging claw (32) formed at the end of the case.

Now, the operation of the above-mentioned device will be described. By driving the motor (M), the power is transmitted to the speed reducer (34) through the joint (20), and the speed reducer (34) is coupled to the coupling. Drive shaft (1 through (27)
8) is driven. Drive roller (23) notch (24)
Engaging with the pin (25) of the drive shaft (18) causes the drive roller (23) to rotate with the drive shaft (18) and the ratchet teeth (21) due to the biasing of the spring (26).
By the meshing of (22), the feeding roller (1
2) rotates. Then, the O-rings (19) (19) and the pressing rollers (13) (1) of the feeding and conveying roller (12)
3) and the bill is sent out.

When the rollers (9) and (10) are normally rotated, the banknotes are sent out to the banknote transport device (1) after the above-described progress. Next, in the case of returning the bill by the counterfeit bill determination, the drive roller (23) is normally rotated by the drive shaft (18) by the engagement of the notch (24) and the pin (25). However, when the bill roller is pulled in the return direction by the reverse rotation of (9) and (10), the O-rings (19) and (19) that are in contact with the bill
Is pulled in the reverse direction by friction, and the delivery and conveyance roller (12) is reversed. That is, the delivery / conveyance roller (12) idles due to the ratchet teeth between itself and the drive roller (23). Therefore, the counterfeit bills are returned by the reversed rollers (9), (10).

Next, the bill pre-reading sensor (16) is turned on.
When a bill is inserted into the N or face-to-face bill validator unit (7), the motor (M) is stopped via the control device and put into a standby state. At this time, the ratchet teeth (21) and (22) of the feeding / conveying roller (12) and the driving roller (23) are connected to the spring (2).
6) is pushed by the drive shaft 6 and meshes therewith, so that the feeding and conveying roller 12 and the O-rings 19 and 19 are connected to the drive shaft 1
8) Does not rotate with the bill, and the tip of the bill is the roller (2) (3)
And the banknotes are reached by the conveyance belts (4) and (5), the banknotes are not conveyed. That is, the bills are held by the feeding and feeding roller (12) and the pressing roller (13) with a force comparable to that of the rollers (2) and (3) of the bill feeding device.

Next, a bill sending-out device (11) is provided for an island with a wide island, but bills that have been inserted into the bill validator (8) and determined to be genuine bills are read in advance as described above. When the sensor (16) is ON or a bill is inserted into the bill validator unit (7), it passes through the rollers (9) and (10) and is held by the rollers (12) and (13). By controlling the drive time of the delivery / conveyance roller (12) of the bill delivery device (11) from the time when the bill passes the rollers (9) and (10) (the drive stop signal of the bill validator is generated), the island width can be controlled. Regardless of whether the bills are wide or narrow, the tips of the bills are aligned with the positions of the rollers (2a) and (3a) shown in FIG. The drive time of the bill feeding device can be set by a combination of ON and OFF of DIPSW, for example.

When setting the drive time of the motor (M) of this bill feeding device, first, when it is necessary to install the bill feeding device together with the bill validator, the switch S _{1 of} FIG. 6 is set, and then FIG. The code is switched to the switch S ₂ S based on the bill feeding device driving time setting table in which the island width, the feeding device, and the length of the coupling guide as shown in FIG.
_3, ON of S _4, and set a combination of OFF, converts the code to the counter value by setting the drive timer time in each format, controls the driving time of the motor (M) of the bill delivery device (11) To do. FIG. 9 shows a flowchart of the control function of the drive time of the bill feeding device.

When the bill feeding device is driven and controlled from the switch portion (37) of the control portion (35) shown in FIG. 5 through the wiring (36), D is set according to the driving time code.
Various values can be set by setting ON / OFF of the IPSW, but as shown in FIG. 9, first, the “DIPSW code reading” (39) is performed at the start (38) of the switch unit (37) of the control unit (35). After that, the process proceeds to step (40) of "Determining counter set value by code", and the counter value corresponding to the code set here is converted and set in the timer counter. In the judgment of "trigger present" (41), the reference level, that is, the presence or absence of a signal at the time of passing the sensor of the bill validator is monitored. When the condition of "with trigger" is satisfied, "counter value subtraction starts" (42), the counter value is subtracted in the cycle of the accurate transmitter, and at the same time, the motor (M) of the bill sending device starts driving. (43) Then, the motor (M) continues to be driven until the counter value becomes zero, and when the counter value becomes zero (44), the driving of the motor (M) is stopped (45). This completes the setting of the drive time of the motor (M).

For example, FIG. 7 shows a combination state of ON and OFF of the setting switch when the set time of the motor drive of the bill feeding device in the case of the M5 of the type shown in FIG. 8 is 0.36 seconds. In the case of the format M ₁ M _{2 in} FIG. 8, the setting time is set to 0 seconds by combining the setting switches. The switch S ₁
If only is ON, the drive timer is set to 0.3 seconds (standard). The control unit (35) of the drive unit that drives the feeding and conveying roller (12) of the feeding device (11),
As shown in FIG. 5, for example, it is provided in the main body of the medal lending machine (46). A switch section (3) having a plurality of switches that can be operated from the outside of the control section (35).
7) is provided. The switch unit is composed of four switches as shown in FIG. 6, and a plurality of various values can be set by combining ON and OFF of the switches.
The switch S ₁ is a switch used for the presence / absence of a bill feeding device in the bill validator, and when the bill feeding device is provided,
Set to ON, or OFF if none. Switches S ₂ , S ₃ and S ₄ are drive time setting switches of the motor of the bill feeding device, and various values are set by combining the ON and OFF of each switch with the code of the set time according to the type in the drive time setting table. , Convert to the counter value corresponding to this code.

As described above, the drive time of the delivery device is set to a plurality of various values by combining a plurality of switches that are turned on and off, the bills are held by the feeding and conveying rollers, and the leading end position of the bills is freely set. be able to. When a bill is held with the tip of the bill reaching the inside of the transport device, if the holding force is equal to or smaller than the transport force of the transport device, the bill is carried in the transport device in an overlapping manner. However, the stacker may cause an error in counting or the stacking and storage may not be possible. However, if the switch value is set so as to stop the leading edge of the bill before reaching the transport device, these obstacles will be eliminated. In any case, even if the lengths of the bill feeding device and the coupling guide are different from each other, by setting various values for the driving time of the bill feeding device by switching ON and OFF, the leading end of the bill is moved to the front of the conveying device. Since the banknote read-ahead sensor can be mounted at the same position regardless of the width of the island.

Further, from the standpoint of product inventory management, the combination guide is a single unit to cope with various island widths, and the bill sending device is integrated with the bill validator, and a plurality of types of stocks are respectively stocked and assembled on site. Often constructed.
In this case, the combination of switches can be set to various values in the field by referring to the bill sending device drive time setting table, etc., of the control unit, so it is sufficient if the control unit is kept in stock. . The initial specifications often change due to site construction circumstances, and the island width is often changed.However, even in this case, refer to the bill sending device drive time setting table and adjust the bill feeding device drive time. Can be dealt with.

[0021]

As described above, according to the present invention, when the bill is recognized by the bill validator and returned, the feeding / conveying roller of the bill feeding device idles to reduce the carrying force, while the bill pre-reading sensor is turned on or face-to-face. During the standby time when the bill is inserted into the bill validator unit, the feeding of the bill can be stopped by stopping the feeding and conveying roller of the bill feeding device. As described above, the return of counterfeit bills is reliable and easy, and the timing of sending out the bills can be adjusted by the bill feeding device, so that the bills are conveyed in the bill conveying device without being overlapped. There is no gap, and the bills are aligned smoothly. In addition, even if the lengths of the bill feeding device and the combination guide used differ depending on the width of the island, the tip position of the bill can be freely set by variously controlling the drive time of the bill feeding device. Therefore, the mounting position of the bill pre-reading sensor can be made constant regardless of the width of the island, and good results can be obtained in the mounting space, standardization of parts and inventory control.
