JP 2003-20152 A Japanese Patent Laid-Open No. 2003-22465

In capturing and transporting with a pair of belt conveyors, the tip of the bill to be sent may be in the correct insertion position. However, if the tip of the bill conveys obliquely with respect to the conveyor surface of the belt conveyor, the tip of the bill hits the conveyor surface and the bill is fed. If the speed is higher, the bill is bent or broken. If the conveyor surface is frictional and difficult to slip, it will be easier to bend and bend. In addition, the leading edge of the bill tends to be damaged when it hits the surface of a rigid belt conveyor or roller.
Also, if the bill feeding speed is slow and the conveyor feed is faster, the bill and the conveyor surface will only hit the bill tip and the bill feeding force (bank bill catching force) will be insufficient, and the belt conveyor will feed idle. The certainty of bill feeding is lost. In addition, the leading edge of the bill is worn by being rubbed by the conveyor belt.

  The problem to be solved by the present invention is to solve these conventional problems, and to capture the banknotes reliably and without wear even if the insertion direction and the insertion speed in which the banknotes are fed are somewhat inappropriate. It is providing the banknote taking-in apparatus which can be sent.

The configuration of the present invention that solves this problem is
1) A bill take-in device that captures and forcibly feeds a bill being sent, and the belt feed direction is parallel to the bill feed direction at the bill destination, and the belt feed surface is slightly smaller than the bill feed trajectory. A bill conveyor belt conveyor is provided at a distant position, and an elastic sheet that can be elastically deformed to a position opposed to the feeding surface of the belt conveyor and that has a sheet facing surface that is slippery is gradually approached according to the feeding direction of the belt conveyor. Are arranged in such a way that the banknote feeding track is in the middle between the front end of the elastic sheet and the belt conveyor belt and the sheet rear surface of the elastic sheet is in contact with the belt feeding surface. The leading edge of the banknotes that come in contact with the elastic sheet and are guided so as to approach the belt conveyor along the opposite surface of the sheet, the feeding surface of the belt conveyor The banknote taking-in apparatus 2) is characterized in that the banknotes can be surely forcibly fed by the conveyor by guiding the banknotes until they come into contact with the elastic sheet and pressing the banknotes against the feeding surface of the belt conveyor. An opening is provided in the center, a bill feeding roller is provided at the position of the opening, and one end of the bill feeding roller is arranged so as to slightly protrude toward the belt conveyor side from the same surface as the opposite surface of the rear surface of the elastic sheet, The banknote taking-in apparatus 3) described in 1) 3) The banknote taking-in apparatus 4) described in 1) or 2), wherein the distance between the front edge of the elastic sheet and the feeding surface of the belt is 10 mm or more, and the front edge of the elastic sheet is curved. The bill taking-in device 5) according to any one of 1) to 3), wherein the elastic sheet is made of polytetrafluoroethylene resin, and the dynamic friction of the opposing surface of the elastic sheet It exists in the banknote taking-in apparatus in any one of said 1) -4) whose friction coefficient is 0.10 or less.

  According to the present invention, the bills to be sent are directed to the frontage between the opposite belt conveyor and the front edge of the elastic sheet (the space between the front edge of the elastic sheet and the belt feed surface), The leading edge of the bill hits an elastic sheet that is attached to close the frontage. Since the bill has a certain degree of rigidity and inertia, when the tip of the bill comes into contact with the opposing surface of the elastic sheet, it slides along the elastic sheet, and the elastic sheet is deformed and displaced so as to expand and the bill is elastic. Gradually approach the belt feeding surface of the conveyor facing the sheet while sliding on the sheet facing surface. And since the rear surface of the elastic sheet comes into contact with the belt feed surface of the conveyor, it finally comes into contact with the belt feed surface while being fed so as to slide along the opposite surface of the elastic sheet. By urging the elastic force of the sheet so that the banknote is pressed lightly from above, the banknote comes into full contact with the feeding surface of the conveyor belt, and the frictional force increases to ensure that the banknote is forcibly fed along with the feeding of the conveyor. It is what is done.

In particular, the elastic sheet is made of polytetrafluoroethylene resin, the coefficient of dynamic friction is about 0.1 or less, and it is easy to slip, and the leading edge of the banknote slides smoothly along the lower surface of the elastic sheet with little resistance. It will be sent down.
In addition, if the distance between the front edge of the elastic sheet and the feeding surface of the conveyor is 10 mm or more, the front edge of the banknote reliably hits the elastic sheet even if the banknote feeding direction and feeding position are slightly varied. The front end of the belt is guided so as to approach the feeding surface of the conveyor, and is brought into contact with the feeding surface of the belt of the conveyor in parallel. Thereby, bills are also sent together with the belt conveyor. In addition, on the rear surface of the elastic sheet, the upper surface of the banknote is pressed downward by the elastic sheet, the banknote is lightly pressed on the conveyor surface, the adhesion force and the frictional force with the conveyor surface are increased, and the banknote is sent together with the conveyor. . Even if the tip of the banknote hits the elastic sheet, the elastic sheet is softly deformed / displaced and the opposing surface of the elastic sheet is slippery, so even if it hits the tip of the banknote, the tip is worn or the banknote is deformed / bent. Never do.

  In particular, if the elastic sheet is polytetrafluoroethylene resin, the lower surface of the sheet is quite slippery, and when the banknote hits the elastic sheet, it slides along the lower surface and is gradually fed downward, guided onto the conveyor surface, The rear surface of the elastic sheet acts so as to cover the upper side, so that the banknote is brought into close contact with the entire surface of the conveyor and reliably sent.

In particular, polytetrafluoroethylene resin in which the sheet surface is slippery is preferable. The dynamic friction coefficient of this polytetrafluoroethylene resin is about 0.05 to 0.10.
In addition, the thickness of the elastic sheet is preferably about 0.4 mm in the use example of polytetrafluoroethylene resin, and it is good that the elastic sheet can be slightly displaced and deformed by the inertial force acting on the front end of the bill. It is preferable that the banknote be smoothly guided in the direction of the conveyor surface by slipping of the elastic sheet surface and deformation / displacement of the elastic sheet itself.

It is preferable that there is a roller that contacts the banknote and forcibly feeds the banknote behind the elastic sheet. The embodiment shown in FIGS. 1 to 12 is opened on the rear surface of the elastic sheet, and a bill feeding roller is provided at the opening position so that the roller is in direct contact with the bill via the opening. 13 and 14 is an example in which a pair of banknote feed rollers is provided at a position separated rearward from the rear end of the elastic sheet. The former is preferable because banknotes can be forcibly fed at an early stage and the feeding is reliable.
Further, the elastic sheet may be provided in a plurality of rows.

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, a banknote is captured by a groove in the center of a V-shaped blade portion behind a vertically long plastic carriage having an X-shaped cross section, and the carriage is moved along the banknote feeding path by an air flow. It is the example which makes it run, and sends it to the banknote taking-in apparatus of a present Example.

In addition, an opening is provided in the center of the rear surface of the elastic sheet, and a bill feeding roller is provided at the opening position. The distance between the belt feed surface of the belt conveyor and the curved leading edge of the elastic sheet is about 12 mm. Further, the distance between the guide inner end 5cu of the carriage guide 5c seen on the lower side in FIG. 4 and the belt feed surface (upper surface) of the belt conveyors 1a and 1b is set to 5 mm.

(Explanation of symbols)
The code | symbol of the banknote taking-in apparatus G of the Example shown to FIGS. 1-12 is demonstrated. This embodiment is used to capture and store banknotes in front of the banknote storage chamber 4b of the banknote transporting apparatus that captures and transports banknotes inserted into a large number of lending machines at a game hall one by one in the carriage. This is an example. Reference numerals 1a and 1b denote belt conveyors of the embodiment, which are a pair of elongated upper and lower belt conveyors that receive only a part of the upper and lower sides of the banknote M. 1c is the banknote taking-in port. Reference numeral 2 denotes an elastic sheet made of polytetrafluoroethylene resin having a thickness of 0.4 mm. The distance between the front edge 2b attached to the attaching member 2a of the elastic sheet, the belt conveyors 1a and 1b, and the belt feeding surface is set to 12 mm. 2c is an opening provided on the rear surface of the elastic sheet 2, 2d is a short banknote feeding roller provided in the opening 2c, 3 is a casing of the banknote taking device G, 4a is a banknote feeding roller behind the belt conveyors 1a and 1b, 4b Is a bill storage chamber having a mechanism (not shown) for storing bills to be fed in piles, 5 is a casing of a bill transport device for running the carriage 5b by air flow, 5a is a carriage feed path, 5b is made of plastic Carriage having V-shaped blade portions 5b ₁ and 5b ₂ , 5c is a carriage guide guide, 5cu is a guide inner end of the carriage guide guide, 5d is a return portion of the carriage 5b, and 5e is a bill discharge of the carriage feed path 5a. It is possible to stop and start the carriage 5b by allowing it to freely move in and out with an electric stopper (not shown).
In addition, the banknote conveyance apparatus is provided with the air blower (not shown), and can send an air flow into the casing 5 of the return part 5d. The air is released by the return portion 5d which is also the end point of the carriage feeding path 5a, and the bill M is slowly fed out by reducing the carriage feeding speed.

In this embodiment, the empty carriage 5b waits below the return portion 5d, and when a bill is inserted into a lending machine (not shown), an electric stopper (not shown) is activated to feed the carriage 5b. Travel with a strong air flow. On the other hand, (not shown) Allowance machine having been put the bill M is sending the bill to the carriage feeding path 5a, a bill M fed to the carriage feeding path 5a carriage 5b is at its V-shaped blade portions 5b ₁ At the entrance of the curved return part 5d which is captured and conveyed by the carriage 5b and is curved at the end of the carriage feed path 5a, the carriage 5b is temporarily stopped or decelerated, and the captured banknote M is discharged by the banknote discharge part 5e. It sends out to the banknote intake 1c in the extension of the carriage feed path 5a. On the other hand, the carriage 5b is rotated by the carriage guide 5c of the curved return portion 5d, and is temporarily stopped by the electric stopper (not shown) at the starting end position (lower position in the figure) of the carriage feed path 5a, and the next rental is performed. When a bill inserted from the machine is sent out to the carriage feed path, it is controlled so as to travel from the starting position by the air flow and to move to the capture and conveyance of the next bill.

  Here, in the banknote taking-in device G of the present embodiment, the carriage 5b is sent from the banknote inlet 1c by the carriage 5b, and the carriage 5b is temporarily stopped, decelerated, or circularly moved at the end of the carriage feeding path 5a (starting end of the return portion 5d). Is started, and the captured banknote M moves to the banknote inlet 1c at a speed sent in the direction in which it is sent, hits the curved opposing surface 2s of the elastic sheet 2, and opposes the elastic sheet 2. It slides along the surface 2s and is sent so as to approach the direction of the belt conveyors 1a and 1b. Since the material of the elastic sheet 2 of the embodiment is polytetrafluoroethylene resin, the facing surface 2s is slippery, and the front end of the banknote M is slid along the curved facing surface 2s of the elastic sheet so that the belt conveyor 1a, Send it closer to 1b. As described above, the bill M moves so as to slide even when it hits the opposite surface of the elastic sheet 2, and the elastic sheet 2 hits the bill M and is deformed / displaced by its inertial force to escape. The tip is less worn and smoothly approaches the belt conveyor.

When the banknote M is guided by the elastic sheet 2 and comes into contact with the belt conveyors 1a and 1b, the elastic sheet 2 presses the banknote M against the belt surface of the belt conveyor with elasticity, and the banknote M presses against the belt surface of the belt conveyors 1a and 1b. Then, the banknote M is sent to the belt conveyors 1a and 1b with certainty and sent to the banknote storage chamber 4b.
Here, since there is a small bill feeding roller 2d in the opening 2c on the rear surface of the elastic sheet 2, the bill M is fed with the feeding force by the roller of the bill feeding roller 2d in addition to the feeding force of the belt conveyors 1a and 1b. M is reliably sent out and sent to the bill storage chamber 4b by a pair of subsequent bill feed rollers 4a.

  Thereafter, the banknote M sent to the banknote storage chamber 4b is stored in a stacked manner by a storage mechanism (not shown) of the banknote storage chamber 4b, and stored and stored so that the next banknote M can be stored. It is.

  In this embodiment, the distance (frontage) between the leading edge of the elastic sheet 2 and the belt conveyors 1a and 1b is about 12 mm, and even if the feeding direction and feeding position of the banknote M are slightly changed, the elastic sheet 2 is curvedly opposed. The leading edge of the banknote M is guided downward along the opposing surface 2s of the lower surface of the elastic sheet 2, and finally the banknote M is parallel to the belt surface and is lightly pressed by the elastic sheet 2 to be sure. Can be fed to the belt conveyors 1a and 1b, and the bills M can be taken in reliably.

The process of taking in banknotes in the embodiment is shown in FIG. 6, FIG. 8, FIG. 9, and FIG.
The process is shown in FIGS. 11 (a), (b), (c) and FIGS. 12 (d), (e), (f).

The apparatus shown in FIGS. 13 and 14 is an example of another banknote taking-in apparatus G2 of the present invention, and the banknote feeding apparatus uses the carriage 5b of the previous embodiment G to send the carriage 5b by air flow, and the same carriage. The bill transport device 5 that captures the bill with the V-shaped front blade portion 5b ₁ is used.
The feature of this other example is that there is no opening on the rear surface of the elastic sheet 2, a long banknote feed roller 2e is provided at a position slightly away from the rear end of the elastic sheet 2, and the belt conveyor 1d also covers the banknote. A flat belt of width and length is used.
Also in this other example, the banknote M hits the elastic sheet 2 and slides on the opposite surface of the elastic sheet 2 to contact the wide belt conveyor 1d. The banknote M is fed by the wide belt conveyor 1d while being pressed by the elastic sheet 2, and is forcibly fed by the long banknote feeding roller 2e when passing through the elastic sheet 2, and then a pair of banknote feeding rollers. It is sandwiched between 4a and sent to the banknote storage chamber 4b, where banknotes are stacked and stored.
Others have the same structure and function as the previous embodiment.

  The example shown in FIG. 15 is another embodiment in which a guide elastic sheet 2x is added in front of the elastic sheet 2 in the embodiment shown in FIGS. The sheet thickness is 0.4 mm for the elastic sheet 2 and 0.3 mm for the elastic sheet 2x, which is thinned. In this other embodiment, the direction and position of the banknote is first largely guided by the elastic sheet 2x and then sent to the feeding surface of the belt by the subsequent elastic sheet 2. Others are the same as that of the Example of FIGS.

Another embodiment of the present invention shown in FIG. 16 is an example in which the carriage 5b is moved so as to reciprocate along a straight path, and the carriage 5b is stopped by a stopper mechanism (not shown) slightly before the banknote inlet 1c. The bill M captured by the blade portion 5b ₁ of the carriage 5b is released and restrained by the guide inner end 5cu of the carriage guide 5c that extends linearly long to the vicinity of the bill intake port 1c. This is an example in which the tip of M surely hits the middle of the curved portion of the tip of the elastic sheet 2. Also in this example, the distance between the guide inner end 5cu at the inner front end of the guide guide 5c and the belt feed surface (upper surface) of the belt conveyors 1a, 1b, 1d is set to 5 mm.

  INDUSTRIAL APPLICABILITY The present invention can be widely used not only for taking bills into a storage room such as a safe for bills to be conveyed at a game hall, but also for bill taking devices for vending machines and bill throwing devices for ticket sales.
