Description

The present invention relates to a paper sheet feeding device that feeds paper sheets as an object to be conveyed to a conveyance path in a conveyance pipe that conveys an object to be conveyed by a conveying fluid that flows from upstream to downstream.

In the past, when conveying thin plastic or paper cards and bills such as paper money, a paper sheet conveying device that sandwiches the paper sheet with a belt or a roller and sends it out has been known, and it has become popular in the market. ing. For example, in a game hall where gaming machines such as pachinko and slot machines are installed, a gaming medium lending device or the like is provided adjacent to the gaming machine, and without banknotes being stocked in this gaming medium lending device, A paper sheet transporting device is used when the bills are transported to and managed by a bank safe. In the paper sheet transporting device of the amusement hall, the bills discriminated by the bill discriminating unit such as the game medium lending device are taken in and attached to the island end of the gaming island where the gaming machine is installed by the transport mechanism including belts and rollers. Carry to the bank safe.

In such a paper sheet transporting device, since a mechanism for sandwiching a banknote by a belt or a roller is used to transport the banknote, there is a problem that the banknote is often jammed at a connecting portion of the belt and the roller. In order to clear a banknote jam, the player playing the game on the gaming machine must interrupt the game, identify the defective part on the game island, and remove the jammed banknotes, causing trouble to the customers. At the same time, the burden on the game shop staff was not small.

In recent years, there has been proposed a paper sheet transporting device that transports a banknote by generating a transporting air stream in a transport tube and placing the air stream on the air stream. If the banknotes are transported by airflow, there is no risk that the banknotes will be jammed in the mechanical parts, because no mechanism such as belts or rollers is used. There has been proposed a paper sheet taking-in device that feeds paper sheets into the conveying pipe of such a paper sheet conveying device (takes in the conveying pipe side) (for example, refer to Patent Document 1). In the paper sheet taking-in device described in Patent Document 1, a shutter is provided on the receiving side of the waiting portion where the bills to be taken in stand by so that the air in the conveying pipe does not leak to the waiting portion at all times. It is a structure that opens the shutter when taking in.

Japanese Patent No. 594221 1

However, the bill capturing device described in Patent Document 1 has a problem that the airtightness is not high although the structure is complicated. In the bill taking device described in Patent Document 1, the shutter is biased to the closed position by the spring, and when the bill is pushed out by the discharging roller, the shutter is displaced to the open position. It is necessary to provide a shutter in the middle of the road. In the first place, the shutter is a technique for opening and closing a hard substance that is not easily deformed by rotating or moving, and it is difficult to realize the hermeticity enough to prevent leakage of a transport fluid such as gas or liquid. Even if the leak from each banknote take-in device is very small, if the leaks from many banknote take-in devices provided in the game island accumulate, the internal pressure on the downstream side of the transport pipe will become extremely low, It may interfere with the bill transportation.

Moreover, in the bill taking device described in Patent Document 1, when the airtightness of the shutter is increased, the pressure difference between the bill waiting portion and the bill waiting portion is increased accordingly, and the high pressure on the side of the conveying pipe serves as a force for holding the shutter in the closed position. This makes it difficult to move the shutter to the open position only by the force of feeding the bill. If the shutter does not open properly due to the momentum of the bills being sent out, there is a risk that the bills will become jammed depending on the state of the bills, so a separate structure for avoiding jams is required, which is generally inefficient.

Therefore, an object of the present invention is to provide a paper sheet feeding device capable of stably feeding paper sheets into the conveying tube while improving the sealing property with the conveying tube.

A paper sheet feeding device for solving the above-mentioned problem is a paper sheet for feeding a paper sheet as an object to be conveyed to a conveying path in a conveying pipe for conveying an object to be conveyed by a conveying fluid flowing from upstream to downstream. A paper feeding device, which includes a main roller that is driven by a driving force and an auxiliary roller that is driven by slidingly contacting the outer periphery of the main roller, and the main roller that is driven and the auxiliary roller that is driven A paper feeding mechanism for feeding, a feeding position for feeding the paper to a paper feeding opening formed at an appropriate position of the conveying pipe, and an auxiliary roller of the paper feeding mechanism for the paper feeding opening. And a displacement mechanism section for displacing the paper sheet feeding mechanism section at a closing position for closing the sheet feeding mechanism.

Further, in the above configuration, a power transmission mechanism unit configured to transmit a displacement driving force for displacing the paper sheet feeding mechanism unit by the displacement mechanism unit as a feeding driving force for driving a main roller of the paper sheet feeding mechanism unit. You may prepare.

Further, in the above-mentioned configuration, the displacement mechanism section causes the auxiliary roller to perform a curving movement to move away from the sheet feeding port so as to move away from the transport path and move to an upstream side or a downstream side of the transport path. As a result, the paper sheet delivery mechanism portion may be displaced from the closed position to the feeding position.

According to the present invention, the auxiliary feed roller of the paper sheet feeding mechanism section normally closes the paper sheet feeding port, so that high sealing performance can be realized. Further, if the displacement mechanism section displaces the sheet delivery mechanism section to the delivery position, the sheet delivery port opens, and the main roller and the auxiliary roller deliver the sheet, so that the sheet delivery port opens. The leaves can be stably fed to the transport path.

Next, an embodiment of a paper sheet feeding device according to the present invention will be described with reference to the accompanying drawings. In addition, the paper sheets that are the transported objects are papers having a shape-retaining property such as banknotes and documents (excluding those that do not have a shape-retaining property with respect to the transport flow such as tissue paper), and are made of resin. Films (including plastic banknotes) and thin cards can be applied. In the banknote transporting device to which the paper sheet feeding device of the present embodiment is applied, a paper currency bill will be described as a banknote transporting device. Further, as the transfer fluid, not only gas but also liquid can be used, but in the banknote transfer device to which the banknote feeding device of the present embodiment is applied, air is used as the transfer fluid.

The banknote feeding device 1 shown in FIG. 1 is used for, for example, a banknote transport device installed in each game island of a game shop. The bill transporting device can be used to collect bills inserted into a game medium lending device, a card selling device, etc. and collect them in one place. The banknotes 3 to be conveyed by passing through the conveying path 2a in the conveying pipe 2 are introduced into the conveying pipe 2 from the bill feeding device 1. A blower 4 is provided at one end of the transport tube 2, and a bill collecting unit 5 is provided at the other end. That is, the air as the carrier fluid flows in the carrier pipe 2 from the upstream side where the blower 4 is provided to the downstream side where the bill collecting unit 5 is provided. It should be noted that by providing a suction device on the downstream banknote collecting unit 5 side, it is possible to cause air as a transport fluid to flow from the upstream side to the downstream side in the transport pipe 2. Further, if the transport pipe is folded back at the end to have a substantially U-shape, the blower 4 and the bill collecting unit 5 can be provided on the same side.

The transport pipe 2 can be connected to a required length and adjusted to a flow path according to the installation location and situation. The bill feeding device 1 that feeds bills to the conveying pipe 2 receives, for example, the bills 3 fed from the gaming machine device 7 provided corresponding to each gaming machine 6 from the bill introducing path 8 and is in the conveying pipe 2. It is sent to the transport path 2a. The game machine 6 is a ball-type game machine, a spinning-type game machine, or the like, and the game machine device 7 rents out a game medium according to the type of the connected game machine 6 according to the inserted amount, or a game. It is a device that issues a game information recording medium that can be used for lending a medium.

As shown in FIG. 2, the bill feeding device 1A of the first embodiment includes a bill feeding mechanism unit 10A and a displacement mechanism unit 20A. Note that the bill feeding device 1A may have a structure that is attached to correspond to the bill feeding port 2b opened at a proper position of the conveying pipe 2, or may have a structure that integrally includes a connecting conveying pipe that includes the bill feeding port 2b. ..

The banknote payout mechanism unit 10A includes a pair of upper and lower main rollers 12 and 12 mounted so that the main shaft 11 is the center of rotation, and a vertically long cylindrical auxiliary roller 14 that is mounted so that the auxiliary shaft 13 is the center of rotation. Have. The peripheral surface of the auxiliary roller 14 is in sliding contact with the peripheral surfaces of the main rollers 12 and 12, and when the main rollers 12 and 12 rotate with the rotation of the main shaft 11 that is directly or indirectly rotated by the feeding drive source 15, The auxiliary roller 14 is driven. When the main shaft 11 rotates in a fixed direction, the side where the peripheral surfaces of the main rollers 12 and 12 and the auxiliary roller 14 come close to each other is the bill receiving side, and the peripheral surfaces of the main rollers 12 and 12 that are in contact with each other are auxiliary. The side where the peripheral surface of the roller 14 goes away is referred to as a bill feeding side.

When the bill 3 is supplied from the bill receiving side to the sliding contact portion between the rotating main rollers 12 and 12 and the auxiliary roller 14, the bill 3 is nipped between the main rollers 12 and 12 and the auxiliary roller 14 and is fed to the bill feeding side. Go. That is, if the banknote receiving side of the banknote payout mechanism section 10A faces the banknote introduction path 8 and the banknote payout side of the banknote payout mechanism section 10A faces the banknote feed-in port 2b, the banknotes from the gaming machine device 7 are transferred. It can be sent to the transport path 2a of the transport tube 2. Further, the main shaft 11 and the auxiliary shaft 13 are rotatably held by, for example, a pair of upper and lower shaft supporting plates 16 and 16, and the sliding contact state between the main rollers 12 and 12 and the auxiliary roller 14 is kept constant.

The displacement mechanism unit 20A includes a rack 21, a worm wheel 22 that is screwed into the gear cutting portion 21a of the rack 21, and a displacement drive source 23 that includes a drive shaft 23a attached to the rotation center of the worm wheel 22. The rack 21 is arranged so as to move the entire bill feeding mechanism unit 10A in the downstream direction (direction of the carrying direction WD) or in the upstream direction (direction opposite to the carrying direction WD) according to the rotation direction of the worm wheel 22. In addition, the rack 21 of the displacement mechanism unit 20A shown in FIG. 2 is configured to move the entire bill feeding mechanism unit 10A by being attached to the main shaft 11, but the present invention is not limited to this, and is attached to the shaft support plates 16 and 16. The entire bill feeding mechanism unit 10A may be moved.

The bill feeding device 1A normally causes the bill feeding mechanism unit 10A to stand by at a position where the bill feeding port 2b is closed by the peripheral surface of the auxiliary roller 14 (closed position shown in FIGS. 2A1 and 2A2). That is, when the banknote payout mechanism section 10A is in the closed position, all four side walls (upstream side vertical wall section 2b1, downstream side vertical wall section 2b2, upper wall section 2b3, lower wall section 2b4) of the banknote feeding port 2b are auxiliary rollers. By closely contacting the peripheral surface of 14, it is possible to efficiently suppress air leakage from the bill feeding port 2b. The material of the auxiliary roller 14 may be chloroprene rubber which is generally used as a sealing material for gas, but since it is used for feeding bills, it is preferable to use fluororubber having higher performance and higher wear resistance. desirable.

The drive source 23 for displacement is driven to drive the worm wheel 22 so that the rack 21 moves the banknote payout mechanism 10A at the closed position in the upstream direction (the direction indicated by the arrow in FIGS. 2A1 and 2A2). Is rotated in a fixed direction (for example, the forward rotation direction). As the rack 21 moves, the peripheral surface of the auxiliary roller 14 is disengaged from the bill feeding port 2b, and the conveyance path 2a and the inside of the bill feeding device 1A communicate with each other via the bill feeding port 2b. Then, at the position where the sliding contact portion between the main rollers 12 and 12 and the auxiliary roller 14 has reached the substantial center of the bill introduction path 8 (the feeding position shown in FIGS. 2B1 and 2B2), the displacement drive source 23 To stop. When the displacement drive source 23 is stopped, the worm wheel 22 is locked in a state of being screwed into the gear cutting portion 21a of the rack 21, so that the bill feeding mechanism 10A is prevented from moving and the bill feeding mechanism 10A is stable. Stop at the feeding position.

When the bill feeding mechanism unit 10A is in the feeding position, the feeding drive source 15 is driven so that the bill receiving side faces the bill introduction path 8 (in FIG. 2(B1), the main roller 12 rotates clockwise and the auxiliary roller 14 so that it is counterclockwise). When the bill 3 is introduced from the bill introduction path 8 to the sliding contact portion between the main rollers 12 and 12 and the auxiliary roller 14, the bill 3 is nipped between the main rollers 12 and 12 and the auxiliary roller 14 and is fed to the bill feeding side. , And is fed into the conveyance path 2a from the bill feeding port 2b. Note that the banknote feed-in port 2b has the downstream side vertical wall portion 2b2 arranged in a tapered shape so that the opening becomes wider toward the downstream side, and the banknotes 3 fed into the conveyance path 2a are warped to the downstream side and conveyed. It has a structure that makes it easy to ride the flow.

For the displacement at the timing when the bill 3 is fed into the conveyance path 2a from the bill feed opening 2b (for example, when the bill sensor that detects the bill 3 fed into the conveyance path 2a from the bill feed opening 2b is turned off). The drive source 23 is driven to rotate the worm wheel 22 in the opposite direction. As a result, the rack 21 moves in the downstream direction, and the bill feeding mechanism 10A is displaced from the feeding position to the closing position. Then, the displacement driving source 23 is stopped at the timing when the bill feeding mechanism unit 10A returns to the closed position where the bill feeding port 2b is closed by the peripheral surface of the auxiliary roller 14. When the displacement drive source 23 is stopped, the worm wheel 22 is locked in a state of being screwed into the gear cutting portion 21a of the rack 21, so that the bill feeding mechanism 10A is prevented from moving and the bill feeding mechanism 10A is stable. Stop in the closed position.

As described above, in the bill feeding device 1A of the first embodiment, the paper sheet feeding mechanism unit 10A that feeds the bills 3 by the driven main roller 12 and the auxiliary roller 14 that is driven is moved to the feeding position by the displacement mechanism unit 20A. Can be displaced to the closed position. That is, since the bill feeding port 2b is normally closed by the auxiliary roller 14 of the bill feeding mechanism unit 10A, high sealing performance can be realized. When the bill 3 is conveyed, the displacement mechanism 20A displaces the bill feeding mechanism 10A to the feeding position. Therefore, the bill feeding port 2b is opened, and the bill 3 is stabilized by driving the main roller 12 and the auxiliary roller 14. Can be sent to the transport path 2a.

The operation control of the feeding drive source 15 and the displacement drive source 23 is performed by a controller (not shown). For example, at the timing of receiving the sensor information for detecting the supply of the bill 3 from the bill introduction path 8 or the timing of receiving the bill transfer start signal from the gaming machine device 7, the control unit causes the displacement drive source 23 to rotate normally. If it is started, the displacement from the closed position to the feeding position is started. The control for stopping the bill feeding mechanism unit 10A at the feeding position may be performed by the rotation amount of the worm wheel 22 which is calculated back from the movement amount of the rack 21, or the movement position of the rack 21 or the bill feeding mechanism unit 10A is detected. You may go by sensor information. When the bill feeding mechanism unit 10A is displaced to the feeding position, the control unit operates the feeding drive source 15 to feed the bill 3 into the conveyance path 2a from the bill feeding port 2b by the bill feeding mechanism unit 10A. Although the stop timing of the feeding drive source 15 may be a time sufficient for feeding the bill 3 into the conveyance path 2a from the bill feeding port 2b, a bill detection sensor provided on the bill feeding side of the bill feeding mechanism unit 10A. It may be a bill currency timing based on the sensor information of. When the bill 3 is fed into the conveyance path 2a from the bill feed port 2b, the control unit promptly starts the reverse rotation of the displacement drive source 23 to perform the displacement from the feed position to the closed position. The control for stopping the bill feeding mechanism unit 10A at the closed position may be performed by the rotation amount of the worm wheel 22 which is calculated back from the movement amount of the rack 21, or the movement position of the rack 21 or the bill feeding mechanism unit 10A is detected. You may go by sensor information.

The banknote feeding device 1A of the first embodiment described above requires the payout drive source 15 for operating the banknote payout mechanism section 10A and the displacement drive source 23 for operating the displacement mechanism section 20A. However, the displacement drive source 23 is not used when the feed drive source 15 is operated, and conversely, the feed drive source 15 is not used when the displacement drive source 23 is operated.

Therefore, the bill feeding device 1B according to the second embodiment is provided with the power transmission mechanism unit 30 that drives both the bill feeding mechanism unit 10B and the displacement mechanism unit 20B by a single drive source. Hereinafter, the bill feeding device 1B according to the second embodiment will be described with reference to FIG. The same components as those of the bill feeding device 1A of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In the bill feeding mechanism unit 10B of the bill feeding device 1B, a belt winding driven pulley 17 is provided on the main shaft 11. That is, the drive source for rotating the main shaft 11 is not provided, and the rotational force of the driven pulley 17 rotated by the power transmission from the power transmission mechanism unit 30 described later becomes the rotational force of the main shaft 11 and the drive force for rotating the main roller 12. Become. Note that the bill feeding mechanism unit 10B is also integrated with a shaft support plate or the like so as to be movable while maintaining the sliding contact state between the main roller 12 and the auxiliary roller 14.

The displacement mechanism unit 20B slides the rack 21, which is once attached to the bill feeding mechanism unit 10B, in the upstream direction or the downstream direction by the rotation of the worm wheel 22 screwed into the gear cutting unit 21a. However, there is no drive source that directly drives the worm wheel 22, and the interlocking shaft 24 is attached to the rotation center of the worm wheel 22. The interlocking shaft 24 is rotated by power transmission from a power transmission mechanism unit 30 to be described later, whereby the worm wheel 22 is normally or reversely rotated, and the rack 21 is slidably moved in parallel with the transport pipe 2 in an upstream direction or a downstream direction. Let

The power transmission mechanism unit 30 transmits the rotational force of the drive roller 32 rotatably attached to the drive shaft 31 that is rotated by an interlocking drive source (not shown) such as a motor, as the displacement drive force of the displacement mechanism unit 20B. After the displacement mechanism unit 20B displaces the bill feeding mechanism unit 10B from the closed position to the feeding position, the rotational force of the drive roller 32 in the power transmission mechanism unit 30 is transmitted as the feeding power of the bill feeding mechanism unit 10B.

First, a structure in which the power transmission mechanism unit 30 transmits the rotational force of the drive roller 32 as the displacement driving force of the displacement mechanism unit 20B will be described. For example, a gear cutting portion 33 a is provided on the lower surface (or upper surface) of the interlocking rack 33 which is arranged so as to be slidable in the direction orthogonal to the transport tube 2, and is engaged with the pinion 34. The rotation center of the pinion 34 is attached to the interlocking shaft 24 of the displacement mechanism section 20B, and the forward/reverse rotation of the pinion 34 associated with the sliding movement of the interlocking rack 33 becomes the forward/reverse rotation of the worm wheel 22 to transfer the rack 21 to the transport pipe 2 It acts as a force that slides in the upstream or downstream direction almost in parallel with. That is, when one end of the interlocking rack 33 (the end near the transport pipe 2) is moved closer to or farther from the transport pipe 2, the main roller 12 and the auxiliary roller 14 are moved in the upstream or downstream direction substantially parallel to the transport pipe 2. Slide to.

A roller contact surface 33b is provided on one side surface (for example, an upstream surface) of the interlocking rack 33, and the interlocking rack 33 is arranged so that the peripheral surface of the drive roller 32 contacts the roller contact surface 33b. Adjust the position. The surface of the roller contact surface 33b is a rough surface that produces appropriate friction. In this way, when the drive roller 32 rotates forward and backward, the peripheral surface of the drive roller 32 does not slip on the roller contact surface 33b of the interlocking rack 33, and works well as a force for sliding the interlocking rack 33.

For example, the bill feeding mechanism unit 10B is set to the closed position in a state where one end of the interlocking rack 33 (the end portion close to the transport pipe 2) is away from the transport pipe 2 (see FIG. 3A). The reference position is detected by, for example, the position detector 41. Alternatively, the reference position of the interlocking rack 33 may be determined by detecting one end (downstream end) of the rack 21 by the position detector 42. The position detectors 41 and 42 may use non-contact type sensors such as optical sensors, or contact type sensors such as limit switches that perform position detection when an object to be detected contacts an action piece or the like. May be.

The drive roller 32 moves in one direction (counterclockwise in FIG. 3B) when the interlocking rack 33 of the power transmission mechanism unit 30 is in the reference position (the bill feeding mechanism unit 10B is in the closed position). When it rotates, one end of the interlocking rack 33 approaches the transport tube 2. With the movement of the interlocking rack 33, the rack 42 moves to the upstream side, so that the bill feeding mechanism 10B is displaced from the closed position to the feeding position. Further, as one end of the interlocking rack 33 approaches the transport tube 2, the other end of the interlocking rack 33 (the end portion far from the transport tube 2) approaches the contact portion of the drive roller 32.

Then, when the other end of the interlocking rack 33 exceeds the contact portion of the drive roller 32 (see FIG. 3C), the driving force of the drive roller 32 does not act on the interlocking rack 33 and the rack of the displacement mechanism section 20B. 21 also does not move. That is, if the bill feeding mechanism unit 10B is set to the feeding position in this state, the rotational force of the drive roller 32 in the power transmission mechanism unit 30 can be transmitted as the displacement driving force of the displacement mechanism unit 20B. It should be noted that when the bill feeding mechanism unit 10B is displaced to the feeding position, if the one end of the drive roller 32 is brought into contact with the outer wall surface of the conveying tube 2, the other end of the rack 33 is driven with a slight error. Even when the roller 32 is not removed from the peripheral surface, the roller 32 can be stopped at the appropriate feeding position. Of course, a contact member for stopping the feeding position is provided separately from the outer wall surface of the transport tube 2, and when one end of the drive roller 32 just hits the contact member for stopping the feeding position, the bill feeding mechanism unit 10B It may be a structure in which is displaced to the feeding position.

Next, a structure in which the power transmission mechanism unit 30 transmits the rotational force of the drive roller 32 as the feeding drive force of the bill feeding mechanism unit 10B will be described. For example, the interlocking shaft 35 is provided with the interlocking roller 36 and the drive pulley 37, and the shaft support plate of the interlocking shaft 35 is integrally attached to the interlocking rack 33. In this way, the interlocking shaft 35, to which the interlocking roller 36 and the drive pulley 37 are attached, also slides in conjunction with the sliding movement of the interlocking rack 33. Further, an interlocking belt 38 is wound around the drive pulley 37 and the driven pulley 17 of the bill feeding mechanism unit 10B, and the driven pulley 17 and the main roller 12 rotate integrally with the rotation of the drive pulley 37. ..

Further, the diameter of the interlocking roller 36 is set to be substantially equal to or slightly protruded from the roller contact surface 33b of the interlocking rack 33, and at the timing when the other end of the interlocking rack 33 deviates from the peripheral surface of the drive roller 32, The peripheral surface of the interlocking roller 36 is brought into contact with the peripheral surface of the drive roller 32. In this way, the interlocking roller 36 receives the rotational force of the drive roller 32 and rotates at the timing when the bill feeding mechanism unit 10B is displaced to the feeding position. For example, as shown in FIG. 3C, when the drive roller 32 rotates counterclockwise, the interlocking roller 36 and the drive pulley 37 rotate clockwise.

The rotation of the drive pulley 37 is transmitted to the driven pulley 17 via the interlocking belt 38, the driven pulley 17 and the main roller 12 rotate clockwise, and the auxiliary roller 14 rotates counterclockwise, as shown in FIG. Rotate around. Therefore, when the bill 3 is supplied from the bill receiving side to the sliding contact portion between the rotating main roller 12 and the auxiliary roller 14, the bill 3 is nipped between the main roller 12 and the auxiliary roller 14 and is fed to the bill feeding side. ..

If the interlocking belt 38 is wound around the drive pulley 37 and the driven pulley 17 with an appropriate tension when the bill feeding mechanism unit 10B is displaced to the feeding position, the rotational force of the driving roller 32 is applied to the bill feeding mechanism unit 10B. Can be transmitted as a drive force for feeding. For example, if the interlocking shaft 35 that moves with the interlocking rack 33 and the main shaft 11 that moves with the rack 21 are designed to move while maintaining an equal distance, the drive pulley 37 and the driven pulley 17 also have an equal distance. Is held, the tension of the interlocking belt 38 is kept constant. However, in the structure in which the rack 21 and the interlocking rack 33 move at a constant speed in the directions orthogonal to each other as in the bill feeding device 1B of the present embodiment, the main shaft 11 and the interlocking shaft 35 move while maintaining an equal distance. Design is impossible. Therefore, if a tension pulley or the like is provided to keep the tension of the interlocking belt 38 constant, even if the separation distance between the main shaft 11 and the interlocking shaft 35 changes, the power from the drive pulley 37 to the driven pulley 17 is reduced. Can be transmitted well.

Further, when returning the bill feeding mechanism unit 10B from the feeding position to the closed position, the interlocking drive source (not shown) is reversed, and the rotation direction of the drive roller 32 attached to the drive shaft 31 is reversed. As a result, the interlocking shaft 35 receives a force in the direction of moving away from the transport tube 2, the peripheral surface of the interlocking roller 36 deviates from the peripheral surface of the drive roller 32, and the feeding power of the bill feeding mechanism unit 10B disappears, and the interlocking rack 33 moves. The roller contact surface 33b comes into contact with the peripheral surface of the drive roller 32. That is, when the drive roller 32 rotates in the reverse direction, the interlocking rack 33 moves in a direction away from the transport tube 2, and the movement of the interlocking rack 33 moves the rack 21 to the downstream side, and closes the bill feeding mechanism unit 10B from the feeding position. Displace to position. When the interlocking drive source is stopped at the position detection timing of the position detector 41 (or the position detector 42) and the drive roller 32 is stopped, the power transmission mechanism unit 30 is returned to the reference position where the bill feeding mechanism unit 10B becomes the closed position. be able to.

As described above, in the bill feeding device 1B of the second embodiment, the power transmission mechanism unit 30 applies the displacement driving force by which the displacement mechanism unit 20B displaces the bill feeding mechanism unit 10B to the main roller 12 of the bill feeding mechanism unit 10B. Can be transmitted as a feeding drive force for driving the. Therefore, both the bill feeding mechanism unit 10B and the displacement mechanism unit 20B can be driven by a single drive source, and cost reduction and weight reduction can be achieved by not requiring a plurality of drive sources.

The banknote feeding devices 1A and 1B according to the above-described first and second embodiments use the rack 21 that slides substantially parallel to the flow path of the transport tube 2 in order to operate the banknote payout mechanism units 10A and 10B. Therefore, when the bill feeding mechanism units 10A and 10B are displaced from the closed position to the feeding position, the peripheral surface of the auxiliary roller 14 that closes the bill feeding port 2b is elastically pressed against the wall portion of the bill feeding port 2b strongly. It will be deformed and come off from the bill feeding port 2b. On the contrary, even when the bill feeding mechanism units 10A and 10B are displaced from the feeding position to the closed position, the peripheral surface of the auxiliary roller 14 is elastically deformed while being strongly pressed against the wall portion of the bill feeding port 2b. It will return to the position where it fits into 2b. When such a force is applied each time the bill feeding mechanism units 10A and 10B are displaced, there is a risk that the auxiliary roller 14 will be quickly worn.

Therefore, the bill feeding device 1C according to the third embodiment is provided with the bill feeding mechanism unit 10C and the displacement mechanism unit 20C capable of suppressing the wear of the auxiliary roller 14. Hereinafter, the bill feeding device 1C according to the third embodiment will be described with reference to FIGS. 4 and 5. The same components as those of the bill feeding devices 1A and 1B according to the first and second embodiments are designated by the same reference numerals and the description thereof will be omitted.

The bill feeding mechanism unit 10C includes a main roller 12 attached to the main shaft 11 and an auxiliary roller 14 attached to the auxiliary shaft 13. It should be noted that the main shaft 11 and the auxiliary shaft 13 do not operate integrally but are curvedly moved by a displacement mechanism section 20C described later. Further, when the banknote payout mechanism unit 10C is in the closed position, the peripheral surface of the main roller 12 does not need to be in contact with the peripheral surface of the auxiliary roller 14 that closes the banknote feeding port 2b. However, when the bill feeding mechanism unit 10C is displaced to the feeding position, the peripheral surface of the main roller 12 always comes into contact with the peripheral surface of the auxiliary roller 14, and the operation of the feeding drive source (not shown) causes the main roller 12 and the auxiliary roller 14 to operate. Allow the roller 14 to rotate.

The displacement mechanism unit 10C includes an interlocking mechanism that causes the main shaft 11 and the auxiliary shaft 13 to curve by a slide shaft 25 attached to the rack 21 that slides in the flow path direction when the displacement drive source 23 operates. The upper and lower ends of the slide shaft 25 are loosely fitted in slide guide holes 26a provided in the pair of upper and lower fixed plates 26, 26, and the slide shaft 25 also moves along the slide guide holes 26a in conjunction with the movement of the rack 21. To do. The slide guide hole 26a is a linear hole that is parallel to the flow path direction, has a width slightly larger than the diameter of the slide shaft 25, and does not obstruct at least the moving range of the slide shaft 25 within the moving range of the rack 21. It is set to the length.

In order to interlock the sliding movement of the slide shaft 25 and the auxiliary shaft 13, the slide shaft 25 is fitted to one end of the pair of upper and lower auxiliary shaft interlocking arms 27, 27, and the auxiliary shaft 13 is fitted to the other end. Further, in order to interlock the slide movement of the slide shaft 25 and the main shaft 11, the slide shaft 25 is inserted into one end of the pair of upper and lower main shaft interlocking arms 28, 28, and the main shaft 11 is inserted into the other end. The auxiliary shaft interlocking arm 27 and the main shaft interlocking arm 28 do not hinder the free rotation of the main shaft 11, the auxiliary shaft 13, and the slide shaft 25, and also prevent excessive rattling from each shaft diameter. It is desirable to provide a shaft insertion hole having a slightly larger diameter.

The fixed plate 26 is provided with a main shaft curved guide hole 26b and an auxiliary shaft curved guide hole 26c. The main shaft 11 inserted in the main shaft interlocking arm 28 is loosely fitted in the main shaft bending guide hole 26b, and the auxiliary shaft 13 inserted in the auxiliary shaft interlocking arm 27 is loosely fitted in the auxiliary shaft bending guide hole 26c. The main shaft bending guide hole 26b and the auxiliary shaft bending guide hole 26c are both arc-shaped equal-width holes that are convex toward the bill receiving side, and the main shaft 11 and the auxiliary shaft bending that are loosely fitted in the main shaft bending guide hole 26b. The auxiliary shaft 13 loosely fitted in the guide hole 26c smoothly curves and moves. In addition, it is necessary to directly or indirectly transmit the driving force of a feeding drive source (not shown) to the main shaft 11 to rotate the main roller 12 in a fixed direction. Therefore, it is desirable to have a feeding drive source mounting structure that does not apply an excessive weight load to the main shaft 11 so that the main shaft 11 can be moved without difficulty by the main shaft interlocking arm 28.

In the bill feeding device 1C configured as described above, the slide shaft 25 is located at the downstream end of the slide guide hole 26a at the closed position where the bill feeding port 2b is closed by the peripheral surface of the auxiliary roller 14. Similarly, the main shaft 11 is located at the downstream end of the main shaft bending guide hole 26b, and the auxiliary shaft 13 is located at the downstream end of the auxiliary shaft bending guide hole 26c (FIGS. 4A and 4B). And FIG. 5(A)).

When the displacement driving source 23 operates while the bill feeding mechanism unit 10C is in the closed position, the rack 21 slides to the upstream side, and the slide shaft 25 pushed by the rack 21 moves along the slide guide hole 26a. Slide to the upstream side. The main shaft 11 inserted into the main shaft interlocking arm 28 is along the main shaft curved guide hole 26b, and the auxiliary shaft 13 inserted into the auxiliary shaft interlocking arm 27 is along the auxiliary shaft curved guide hole 26c. Curve to move. That is, the main roller 12 and the auxiliary roller 14 do not move linearly in the rack 21, but move in the same curved trajectory as the shapes of the main shaft curved guide hole 26b and the auxiliary shaft curved guide hole 26c (see FIG. ), (C)), and is displaced to the bill feeding position. Therefore, when the bill feeding mechanism unit 10C is displaced from the closed position to the bill feeding position, it is possible to prevent the peripheral surface of the auxiliary roller 14 from being rubbed while being strongly pressed against the wall portion of the bill feeding port 2b.

Further, when the displacement driving source 23 is reversely rotated in the state where the bill feeding unit 10C is at the bill feeding position, the rack 21 slides to the downstream side and is pulled by the rack 21 and the slide shaft 25 slides the slide guide hole 26a. Slides to the downstream side. The main shaft 11 inserted into the main shaft interlocking arm 28 is along the main shaft curved guide hole 26b, and the auxiliary shaft 13 inserted into the auxiliary shaft interlocking arm 27 is along the auxiliary shaft curved guide hole 26c. Curve to move. That is, the main roller 12 and the auxiliary roller 14 move not in a linear movement of the rack 21 but in a curved locus having the same shape as the main shaft curved guide hole 26b and the auxiliary shaft curved guide hole 26c, and are displaced to the closed position. To do. Therefore, even when the bill feeding mechanism unit 10C is displaced from the bill feeding position to the closed position, it is possible to prevent the peripheral surface of the auxiliary roller 14 from being rubbed while being strongly pressed against the wall portion of the bill feeding port 2b.

As described above, in the bill feeding device 1C of the third embodiment, when the displacement mechanism unit 20C displaces the bill feeding mechanism unit 10C from the closed position to the bill feeding position, the auxiliary roller 14 moves away from the conveyance path 2a. The curved movement moves away from the feeding port 2b and moves to the upstream side of the transport path 2a. Therefore, it is possible to effectively suppress the problem that the auxiliary roller 14 is pressed against the wall portion of the bill feeding port 2b and is worn out every time the bill feeding mechanism unit 10C is displaced.

In the structure of the bill feeding mechanism unit 10C in the bill feeding device 1C of the third embodiment, since the main roller 12 is arranged on the downstream side of the auxiliary roller 14, when the main roller 12 is displaced from the closed position to the bill feeding position. Then, the auxiliary roller 14 was curvedly moved to the upstream side. However, in the case of the bill feeding mechanism unit 10C in which the main roller 12 is arranged on the upstream side of the auxiliary roller 14, when the main roller 12 and the auxiliary roller 14 are curvedly moved to the downstream side when being displaced from the closed position to the bill feeding position. Just go. Further, the structure of the displacement mechanism section 20C in the bill feeding device 1C of the third embodiment is for moving the main roller 12 and the auxiliary roller 14 in a curved manner along a curved guide hole, but is not limited to this. Instead, the curved movement may be realized by a known existing link mechanism.

In the above-described bill feeding devices 1A to 1C of the first to third embodiments, only the auxiliary roller 14 of the bill feeding mechanism units 10A to 10C has the function of the leak prevention valve that closes the bill feeding port 2b. However, in the bill feeding device 1D according to the fourth embodiment shown in FIG. 6, the main roller 18 having the same shape as the auxiliary roller 14 is used, and the bill feeding port 2b is closed by the main roller 18 and the auxiliary roller 14. .. Hereinafter, the bill feeding device 1D according to the fourth embodiment will be described with reference to FIG. The same components as those of the bill feeding devices 1A to 1C according to the first to third embodiments are designated by the same reference numerals and the description thereof will be omitted.

The bill feeding mechanism unit 10D of the bill feeding device 1D according to the fourth embodiment is configured such that a main roller 18 and an auxiliary roller 14 are attached to a main shaft 11 and an auxiliary shaft 13 which are pivotally supported by a pivot support plate 16, respectively. Although the main roller 18 and the auxiliary roller 14 are made of the same material and have the same structure, the main roller 18 is, for convenience, attached to the main shaft 11 which is directly or indirectly rotated by a feeding drive source. The main roller 18 and the auxiliary roller 14 both have a function of a leak prevention valve that closes the bill feeding port 2b. The auxiliary roller 14 arranged on the upstream side closes the entire area of the upstream vertical wall portion 2b1 and the upstream portions of the upper wall portion 2b3 and the lower wall portion 2b4. The main roller 18 arranged on the downstream side blocks the entire area of the downstream side vertical wall portion 2b2 and the downstream side portions of the upper wall portion 2b3 and the lower wall portion 2b4. Of course, the sliding contact portion between the main roller 18 and the auxiliary roller 14 is also in a close contact state so that air does not leak. Further, the sliding contact portion between the main roller 18 and the auxiliary roller 14 is arranged so as to face the banknote introduction path 8, and the banknote 3 supplied from the banknote introduction path 8 is directly connected to the main roller 18 and the auxiliary roller 14. Reach the sliding contact part of. Therefore, the bill feeding mechanism unit 10D does not need to move to the upstream side or the downstream side when receiving the bill to be sent to the transport path 2a.

The displacement mechanism unit 20D of the bill feeding device 1D according to the fourth embodiment is provided with a rack 21 so as to slide in a direction orthogonal to the transport path 2a, and a worm wheel 22 that meshes with a gear cutting portion 21a of the rack 21. The drive source 23 for displacement rotates forward and backward. For example, by rotating the worm wheel 22 forward, the rack 21 slides in a direction away from the transport tube 2 (hereinafter referred to as “front”), and by rotating the worm wheel 22 in the reverse direction, the rack 21 approaches the transport tube 2. It slides (hereinafter referred to as "backward"). Since the rack 21 is connected to the shaft support plate 16 and the like of the bill payout mechanism unit 10D, the entire bill payout mechanism unit 10D slides back and forth according to the back and forth movement of the rack 21.

In the bill feeding device 1D configured as described above, if the main roller 18 is rotated at the closed position (see FIG. 6A) where the main roller 18 and the auxiliary roller 14 close the bill feeding port 2b, the bill is introduced. It is also possible to pay out the bills 3 supplied from the path 8. However, when the main roller 18 and the auxiliary roller 14 in a state where the bill feeding port 2b is closed are rotated, strong friction is generated between the bill feeding port 2b and the wall portion of the bill feeding port 2b, and the feeding drive source is overloaded. There is a concern that the peripheral surfaces of the main roller 18 and the auxiliary roller 14 may be worn.

Therefore, in the bill feeding apparatus 1D of the present embodiment, the displacement mechanism 20D moves the bill feeding mechanism 10D forward to displace the bill feeding position (see FIG. 6B). That is, when the bill feeding mechanism unit 10D is displaced to the bill feeding position, the main roller 18 and the auxiliary roller 14 are separated from the bill feeding port 2b, and the main roller 18 and the auxiliary roller 14 contact the wall portion of the bill feeding port 2b. Disappear. Therefore, if the bill feeding mechanism unit 10D is displaced to the bill feeding position, friction does not occur between the main roller 18 and the auxiliary roller 14 and the wall portion of the bill feeding port 2b.

Moreover, when the bill feeding mechanism 10D is displaced from the closed position to the bill feeding position, the moving distance by the displacement mechanism 20D is a short distance in which the main roller 18 and the auxiliary roller 14 do not come into contact with the wall portion of the bill feeding port 2b. good. If the displacement distance from the closed position to the bill feeding position can be shortened, the time required for the displacement can be shortened and the power consumption of the displacement mechanism section 20D can be suppressed. Furthermore, if the displacement distance from the closed position to the bill feeding position can be shortened, the gap between the main roller 18 and the auxiliary roller 14 and the wall portion of the bill feeding port 2b also becomes narrow, so that the bill feeding mechanism unit 10D is set to the bill feeding position. There is also an advantage that air leakage when displaced can be suppressed.

Although the paper sheet feeding apparatus according to the present invention has been described above based on the embodiments, the present invention is not limited to these embodiments and is realized unless the configuration described in the claims is changed. It covers all possible sheet conveying devices as a scope of right.
