Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a paper sheet feeding device for a paper sheet recognition machine.

(b) Conventional technology Conventionally, this type of paper sheet identification machine conveys the inserted paper sheet to the identification device, and when the identification device determines the suitability of the paper sheet, it rotates in the forward direction and transfers the paper sheet to the storage. A configuration is generally known that is equipped with a conveying device that conveys the article to a foreign country, and when it determines that it is fraudulent, turns it around and returns it, as shown in, for example, Japanese Utility Model Application Publication No. 56-60162.

(c) Problems to be solved by the invention A paper sheet identification machine with such a configuration stores paper sheets in a storage, and when the storage is almost full, the paper sheet identification machine Since the leaf is interposed near the entrance of the storage, if the conveyance device of the paper sheet identification machine is reversed due to the return operation due to fraudulent paper, the paper in the storage will be rolled into the identification machine and returned. There was a risk that it would get stuck inside the identification machine.

In view of the above points, the present invention provides a device that prevents paper sheets from becoming entangled in a storage compartment and prevents paper sheets from jamming within an identification machine.

(d) Measures to solve the problem The inserted paper sheet is transported to the identification device, and when the identification device determines whether the paper sheet is appropriate, it rotates in the normal direction and transports the paper sheet to the storage to prevent unauthorized use. In a paper sheet discriminator equipped with a paper sheet conveying device that reverses and returns the paper sheet when it is discriminated, a pair of rollers facing each other across the entrance is provided at the entrance of the storage, and one of the rollers has a one-way rotating clutch on the shaft. The other roller is pivotally supported so as to be movable between a position in which it is in pressure contact with one roller and a position in which it is separated from the other roller. The leaves are carried into the storage by holding them, and when the rollers are reversed, the rotation of the rollers is stopped by the one-way rotating clutch, and the other roller is separated from one roller by a control member operated by the reversal of the conveying device. It is configured to move the camera to the desired position.

(e) Function: A pair of rollers are placed opposite each other at the entrance of the storage compartment, and when the conveying device rotates in the forward direction, the paper sheets are held between them and taken into the storage compartment, and when the conveyance device rotates in the forward direction, they are rotated by a one-way rotating clutch. By stopping, paper sheets are prevented from being caught in the storage, and the pair of rollers are separated from each other by a control member,
Since the paper sheet returned by the conveyance device is not pinched by the pair of rollers and no extra load is applied to the paper sheet, jamming of the paper sheet inside the discriminator during reversal is prevented.

(F) Embodiment The drawings show an embodiment of the present invention, in which 1 is a paper sheet recognition machine that determines the suitability of paper sheets. 2 is a conveyance device provided in the identification device 1, and pulleys 3A, 3B, 3
A belt 4 is stretched between C, and rollers 5A, 5B, 5C, and 5D are provided in contact with the belt 4, and paper sheets are held between each of the rollers 5A, 5B, 5C, and 5D and the belt 4. It is designed to be transported by hand.
That is, when a sheet of paper is inserted into the insertion slot 6, the detector 7 detects the insertion of the sheet of paper and causes a motor (not shown) to rotate in the normal direction, and the sheet of paper is held between the belt 4 and the roller 5A and taken in. During transportation, identification device 8
Paper sheets are now identified by this method. When the inserted paper sheet is determined to be appropriate by the identification device 8, it is further rotated in the normal direction and the paper sheet is placed in the storage compartment 9.
transport in the direction. Further, if it is determined that the paper is fraudulent, a motor (not shown) is reversed to return the paper to the insertion slot 6.

10 and 11 are at the entrance 9A of the storage 9;
These are a pair of rollers for taking in that face each other with A in between. This roller 10 is provided with a pulley 14 having a one-way rotation clutch 13 installed therein on a shaft 12, and a belt 15 between this pulley 14 and the pulley 3C.
is constructed so that when the conveying device 2 rotates forward, it rotates in conjunction with the direction in which the sheet is taken in. When the conveying device 2 rotates in the reverse direction, only the pulley 14 is rotated by the action of the one-way rotation clutch 13. is reversed so that the roller 10 is not rotated. On the other hand, the roller 11 is rotatably supported on a shaft 16 and positioned corresponding to the roller 10, and
The shaft 1 is movable back and forth between a position in pressure contact with the roller 10 and a position away from the roller 10.
6 is movably supported on the wall surface of the entrance 9A. The shaft 16 is biased by the elasticity of a spring 17 so as to press the roller 11 against the roller 10.

Reference numeral 18 denotes a movable shaft connected to the shaft 16 via a connecting member 19, and the other end is movably provided with one end as a fulcrum, and a control member 20 is provided on the movable end side. This control member 20 has one end connected to the movable shaft 18.
The control section 20A at the other end is in contact with a control shaft 21 that pivotally supports the shaft 12,
Moreover, it is adapted to be operated by an operating rod 22 provided on the pulley 14. That is, as shown in FIG. 3, when the pulley 14 rotates in the direction of the arrow indicating normal rotation, the control member 20 positions the control portion 20A below the control shaft 21 by the operating rod 22, as shown in FIG. As shown in FIG.
As shown in FIG. 5, when the pulley 14 rotates in the reverse direction of the arrow, the operating rod 22 positions the control unit 20A above the control shaft 21. As shown in FIG. 4, the roller 11 is configured to be in a spaced apart position from the roller 10. 23 is a spring that supports the control member 20, and 24 is a stopper that comes into contact with the control portion 20A of the control member 20.

Therefore, the forward rotation of the conveying device 2 causes the pulley 1 to
4 rotates normally, the control member 20 positions the roller 11 in pressure contact with the roller 10, and the conveying device 2
The paper sheets conveyed by the rollers 10 and 11
It can be taken into the storage 9 by being held between them.

Further, when the conveyance device 2 is reversed, only the pulley 14 is reversed by the action of the one-way rotation clutch 13, and the driving force is not transmitted to the rollers 10 and 11, so that the sheets in the storage 9 are not rolled up.

Further, when the pulley 14 is reversed, the control member 20 positions the roller 11 away from the roller 10, so that the sheet conveyed by the conveyance device 2 is no longer pinched between the rollers 10 and 11. That is, when the rollers 10 and 11 are holding the banknotes,
When attempting to return a sheet of paper located across both the belt 4 and rollers 10 and 11 of the conveyance device 2 by reversing the conveyance device 2, the sheet of paper is pulled by the belt 4, but the rollers that are stopped are pulled. 10,11
If the rollers 10 and 11 are holding a banknote between them, it will act as a resistance to conveyance and cause the banknote to slip or jam, but by separating the rollers 10 and 11, the resistance of the banknote to be returned is reduced, preventing the banknote from slipping or jamming. can do.

(g) Effects of the invention As described above, the present invention has a pair of rollers installed oppositely at the entrance of the storage with the entrance in between, and when the conveying device rotates forward, the paper sheets are held between them and taken into the storage. Since they are designed to stop rotating and to separate from each other during reverse rotation, it is possible to reliably prevent paper sheets from jamming during reverse rotation.
