Where banknotes for storing the bill cassette 10 is stored, there is provided a bill separator 12 for separating the bills stored therein for delivery to the feed module 20 one by one. The banknote separator 12 is driven by a DC motor 25 provided on the feed module 20 side.

That is, the driving force of the DC motor 25 is transmitted through the worm gear 14 extending into the bill cassette 10 to drive various components for separation of bills. For example, in order to discharge the bills one by one, the pickup roller 16 installed inside the bill cassette 10 is driven to guide the bills to the guider 18 side. Reference numeral 17 is a guide roller.

Banknotes discharged from the banknote cassette 10 are transferred to the banknote detection unit 30 by the feed module 20. At this time, in the feed module 20, banknotes are conveyed by a belt v and a roller 20r driven by a plurality of pulleys p.

In the thickness detection unit 30, the thickness is detected while the banknote is transferred by the roller 30r. In the thickness detection unit 30 as described above, two bills are sensed to be transferred at a time.

Banknotes passing through the thickness detection unit 30 is transferred from the delivery module (40). In the delivery module 40, the bill is delivered to the discharge unit 42 for delivering the bill to the customer, and the bill is recovered by the separate path by collecting the bad banknote and the two bills transferred at once. Will be transferred.

In the delivery module 40 as well, banknotes are transferred by a plurality of pulleys 40p, belts 40v, and rollers 40r. In addition, a driving motor 45 for driving pulleys, belts, and rollers of the feed module 20, the thickness detection unit 30, and the delivery module 40 is provided at one side of the delivery module 40. The power of the drive motor 45 is transmitted to the driven pulley 48 by the belt 47 wound on the drive pulley 46, and the pulley and the roller from the driven pulley 48 to the belt and gear, etc. Is passed using.

In the conventional banknote automatic dispenser having such a configuration, the banknotes contained in the banknote cassette 10 are separated one by one by the banknote separator 12 driven by the DC motor 25 and the feed module 20. Is delivered to, and detects that the two sheets are simultaneously delivered from the thickness detection unit 30 via the feed module 20 is delivered to the delivery module 40. In the delivery module 40, the banknotes are delivered to the discharge unit 42 accessible to the customer. And, the bad banknotes or banknotes delivered at the same time two sheets are recovered to the collection box (50).

First, the transfer system for transferring bills is composed of pulleys, belts and rollers, etc., which is very complicated. In particular, the bill dispenser is composed of a plurality of modules, so many unnecessary configurations are used for the transfer between these modules. In addition, due to the complicated transfer system, a lot of jams are generated during bill transfer.

In addition, since the banknote transfer system is made by assembling a plurality of modules, the banknote transfer system is not precisely formed due to the assembly tolerance between the respective modules, and many problems occur during banknote transfer at the connection portion between these modules.

And since the conventional configuration uses a plurality of belts and modules connected to each other, when the entire mechanism constituting the banknote dispenser is installed upside down, it cannot be properly operated, and the conventional structure can only do the top discharge. There was also a problem that could not be made into a form of product.

Therefore, an object of the present invention is to solve the problems of the prior art as described above, to simplify the bill transfer system and to perform the separation and transfer of bills using one drive motor.

Another object of the present invention is to provide an automatic banknote dispenser composed of one whole bill transfer system rather than a separate module.

On the other hand, the bill separating unit 140 is provided with a pickup roller 142 for taking out the bills of the bill cassette 130 one by one. In such a pickup roller 142, a rubber part (not shown) is formed in a predetermined section in order to take out the bill from the bill cassette 130 using friction with the bill, and the remaining sections are formed in a smooth surface. A guide 143 for guiding the bills picked up by the pickup roller 142 extends from the pickup roller 142 toward the transfer roller 144 to be described below.

And, as shown in Figure 5, a feed roller 144 for transporting the bill picked up in the pickup roller 142 is installed coaxially to the drive shaft (197). Such a transfer roller 144 rotates integrally with the drive shaft 197, and a rubber section 144 ′ for transferring the transfer roller 144 using friction with banknotes is formed at a predetermined interval, and the rest of the transfer roller 144 is formed. The sections are formed with smooth sides.

Separation roller 146 is installed in close contact with the feed roller 144. The separation roller 146 is rotated in the same direction as the feed roller 144 to separate the overlapped conveyed from the bills conveyed by the feed roller 144.

A driving pulley 145 is coaxially installed on the feed roller 144 for rotation in the same direction of the feed roller 144 and the separation roller 146, and the driven pulley 147 is also coaxial to the separation roller 146. ) Is installed, and the pulleys 145 and 147 are connected to the belt 145v.

The transfer guide 149 having a predetermined curvature guides the banknotes passed between the transfer roller 144 and the separation roller 146 to the banknote transfer path described below.

A plurality of pairs of feed rollers are installed to transfer the bills guided by the feed guide 149.

First, the first feed roller pairs 150 and 150 'are installed side by side so as to be driven by the third driving gear 126. In this case, the first feed roller 150 is driven by the third drive gear 126 and the first feed roller 150 ′ corresponding thereto is rotated by friction with the first feed roller 150.

The second feed roller pairs 152 and 152 'are arranged side by side on the upper portions of the first feed roller pairs 150 and 150' to be driven by the second driving gear 122. In addition, the third feed roller pairs 154 and 154 'are installed side by side so as to be driven by the first driving gear 121. Here too, power transfer is achieved by friction between the feed roller pairs 152, 152 ', 154, 154'.

The feed roller pairs 150, 150 ', 152, 152', 154, 154 'are installed to form a straight path. In this case, along the straight paths formed by the transfer roller pairs 150 and 150 ', 152 and 152' and 154 and 154 ', the transfer guide plates 155 are installed at both sides to guide the transfer of bills.

Here, the rotation detecting sensor 151 for detecting the rotation state of the drive motor 110 is installed adjacent to the first feed roller 150. The rotation sensor 151 detects the rotation of the rotation wheel 150w coaxially installed in the first transfer roller 150 to detect the rotation state of the drive motor 110.

As described above, a configuration for transferring the banknotes transferred along the straight path to the customer payout port 170 or the collection box 180 is transmitted. The driving force for switching the conveying path of the banknote conveyed along the straight path is provided by the solenoid 160. The diverter 162 is connected to the drive plate 161 of the solenoid 160. The diverter 162 has a front end portion installed at the end of the straight path to switch the path in which the bill is moved by the driving of the solenoid 160. To this end, first and second guide surfaces 162a and 162b are formed at both ends of the diverter 162 in both directions. Reference numeral 163 denotes a detection sensor for detecting an initial operation of the solenoid 160.

Meanwhile, the discharge roller 164 and the recovery roller (164) and the recovery roller (164) correspond to the third pair of transport rollers 154 and 154 'for transporting the banknotes whose transport path is determined by the diverter 162 after being transported along the straight path. 166 is installed. The release roller 164 cooperates with the third moving roller 154 to deliver the bill to the customer payout 170. In addition, the recovery roller 166 cooperates with the third moving roller 154 ′ to transfer the paper money to the collection box 180. Here, the discharge roller 164 and the recovery roller 166 are driven by friction with the third pair of transport rollers 154 and 154 ', respectively.

Next, the ejector sensor for detecting the bill is discharged from the customer payout 170 to count the number of bills released, and provides a signal for driving the bill separating unit 140 for the next bill release operation ( 172 is installed at the customer payout 170 side.

The recovery path is provided with a recovery sensor 182 that detects the collection of the bill and provides a signal for driving the bill separation unit 140 for the next bill release operation.

Next, in the straight path, the thickness of the transfer sensor 180 is detected by detecting the thickness of the preparation sensor 190 for providing various signals necessary for driving the paper money and transferring the paper money to be transferred in duplicate. The detection sensor 192 is provided. The preparation sensor 190 detects that the bill is transferred by the first feed roller pairs (150, 150 ') to prepare for the operation of the thickness detection sensor 192, and accordingly driving and driving the solenoid 160 It provides a signal for driving stop of the banknote separator 140.

Hereinafter, an embodiment of the present invention having the configuration as described above will be described with reference to the flowchart shown in FIG. 6. When the discharge command of the banknote is given, the drive motor 110 is rotated to provide power. At this time, the solenoid 160 is in an off state and the rotation sensor 151 operates to detect the rotational speed of the drive motor 110 so that the bills can be transported at a constant speed.

And the pick-up roller 142 of the bill separating unit 140 received the driving force of the drive motor 110 is rotated to pick up the bills inside the bill box 130 one by one. Then, the bill picked up by the pickup roller 142 is guided along the guide 143 is transferred to the transfer roller 144.

At this time, the power of the drive motor 110 is transmitted to the driven gear 198 through the clutch drive gear 128 to the driven gear 198 through the intermittent drive unit 196 from the driven gear 198. As such, the feed roller 144 rotates by the driving force transmitted to the drive shaft 197. The drive of the pickup roller 142 is transmitted to the pickup roller 142 through the pickup driving gear 199 and the idle gear 129 installed on the driving shaft 197.

Then, the bills are transported by the rotation of the transport roller 144, and the bills overlapped and transported by the separation roller 146 rotating in the same direction as the transport roller 144 are separated. At this time, the separated bill is guided to the guide 143 by a mechanism (not shown). Here, the mechanism for guiding the separated banknote in the guide 143 is already known, and thus the configuration and operation description thereof are omitted. In this way, the paper money remaining in the guide 143 is transported and discharged by the feed roller 144 at the next bill release command. At this time, the feed roller pairs 150, 150 ', 152, 152', 154, 154 'continue to rotate.

Meanwhile, the banknotes normally transferred are guided by the transfer guide 149 through the transfer roller 144 and the separation roller 146 by the continuous rotation of the transfer roller 144, and the front end portion thereof is guided by the first transfer roller pair. Is passed between 150 and 150 '. And bills are guided to the transfer guide plate 155 by the first pair of transport rollers 150 and 150 'and start to be transferred along a straight path.

At this time. When the tip portion of the bill passing through the first feed roller pair 150, 150 ′ is detected by the preparation sensor 190, the preparation sensor 190 issues an operation preparation command of the thickness detection sensor 192, and the bill The power transmitted to the separation unit 140 is blocked. That is, the intermittent driving unit 196 is separated from the driven gear 198 so that the banknote separating unit 140 is no longer operated so that no banknotes can be ejected from the banknote cassette 130.

Then, when the bill is continuously transferred, the thickness detection sensor 192 detects the thickness of the bill and detects that two sheets are overlapped and transferred. That is, by detecting the thickness difference between the case where one sheet is transferred and the two sheets are overlapped, only one sheet is normally transferred.

Next, after passing through the thickness detecting sensor 192, the banknotes are transferred by the second feed roller pairs 152 and 152 'and the third feed roller pairs 154 and 154'. And when the bill is transferred by the transfer roller pair as described above, the transfer guide plate 155 is a linear movement of the bill.

In addition, when it is determined that one bill is conveyed by the thickness sensor 192, the bill conveyed by the third feed roller pairs 154 and 154 'is left in an initial state without operating the solenoid 160. Guided to the first guide surface 163a of the diverter 162 is delivered to the customer outlet 170 by the discharge roller 164 and the third transfer roller 154.

At this time, the eject sensor 172 detects the release of the bill, counts the number of bills released, and provides a signal for detecting the completion of the bill to allow the bill separator 140 to be operated again. That is, the intermittent drive unit 196 is connected to the driven gear 198 to receive the driving force of the drive motor 110 transmitted through the clutch drive gear 128.

On the other hand, when it is determined in the thickness sensor 192 that the multiple bills are overlapped and transmitted or is determined to be a bad bill, the solenoid 160 is operated by the detection signal so that the diverter 162 shows FIG. 2. The paper money is guided to the second guide surface 162b by being rotated in the clockwise direction, and the paper money is collected by the third conveying roller 154 'and the collecting roller 166 into the collecting box 180.

At this time, the collection sensor 182 detects the number of bills to provide a signal so that the bill separating unit 140 can perform the following operation. Then, after collecting the bills in the collection box 180, the bill separating unit 140 is operated again according to the signal of the collection sensor 182 to separate and transfer the next bill.

After the bills are released or recovered in this manner, the above operation is repeated again, and after the number of bills desired by the eject sensor 172 is counted, the driving motor 110 is turned off to complete the operation.

Although the present invention having the configuration as described above has been described with an automatic banknote dispenser as an example, the present invention is not limited thereto and may be applied to a ticket vending machine for the release of various tickets.

The automatic banknote dispenser according to the present invention as described in detail above can selectively reduce the size of the automatic banknote dispenser as a whole by selectively driving the power transmitted to the banknote separating unit so as to integrate the components and drive it with one driving motor. do.

And the whole structure is installed inside one case, and the path for the transfer of banknotes is straightened as a whole, and rollers are used for the transfer. When the mechanism is installed upside down, the release position of banknotes can be freely selected. It can meet the needs.

And the path for the transfer of bills is straightened, so that the occurrence of jams during bill transfer is greatly reduced, and since only one driving motor is used as a whole, the structure is simplified and thus manufacturing cost can be lowered.
