The feeding device 16 of the present invention is applied to feeding out banknotes from the banknote stacking sections 12D to 12F.

The details of the feeding device 16 will be explained below with reference to FIGS. 3 to 5.

The bill stacking section 1A is formed inside a placing plate 17 on which the banknotes 2 are placed and a vertical plate 18 that forms an opening 4 between the placing plate 17 and through which the banknotes 2 pass. This vertical plate 18 has the function of bringing the banknotes 2 stacked in the vertical direction into contact with each other and aligning their end faces. Further, a kicking roller 3A is provided below the placement plate 17,
By rotating around the shaft 19, the kicking roller 3A has protrusions 20 protruding in the radial direction.
The stacked banknotes 2 are intermittently projected onto the mounting plate 17.
is moved up and down to promote movement of the bill 2 in the surface direction.

A feed-out roller 21 is provided in front of the kick-out roller 3A in the kicking direction, and this feed-out roller 21 rotates together with a shaft 22 parallel to the axis 19 of the kick-out roller 3A. . Further, a frictional feeding portion 23 is provided on a part of the outer periphery of the feeding roller 21 so as to contact the lower surface of the banknote 2 and draw it forward. It is composed of a large number of friction protrusions 24 protruding from the circumferential surface of the feed roller 21. Note that the circumferential length of the friction feeding section 23 is set to be smaller than the size of the smallest banknote (for example, 1,000 notes) stored in the banknote stacking section 1A.

Further, the shaft 22 of the feeding roller 21 has a first
A belt roller 25 is rotatably supported, and the radius R ₁ of this belt roller 25 is equal to the radius of the friction feeding portion 23 of the feeding roller 21.
It is set smaller than R ₂ by at least the thickness of one banknote. Furthermore, the first belt roller 25
A second belt roller 26 is provided near the shaft 22, and this belt roller 26 is fixed to a shaft 27 parallel to the shaft 22. A belt 29 is wound around these first and second belt rollers 25, 26 and idle rollers 28A to 28C, and this belt 29
The paper money 2 is conveyed while being held between the paper money 2 and the paper money 5. Further, guide plates 30 and 31 are provided outside the second belt roller 26 in the radial direction, and these guide plates 30 and 31 are fed out from between the first belt roller 25 and the belt 29. The bill 2 is curved along the outer periphery of the second belt roller 26 and transferred to the belt 29 and the distribution conveyance mechanism 14.
It acts as a guide between the belt 32 and the belt 32.

Next, the drive mechanism of the feed roller 21, belt rollers 25, 26, etc. will be explained with reference to FIG.

That is, reference numeral 33 in FIG. 5 is a drive shaft, and this drive shaft 33 drives the drive shaft 36 of the belt 32 through gears 34 and 35, and drives the intermediate shaft 38 through gears 34 and 37. There is. This intermediate shaft 38
A pulley 40 is supported via an electromagnetic clutch 39, and this pulley 40 is connected to a drive belt 4.
1, a pulley 42 integral with the shaft 22 is driven. Further, a pulley 43 is fixed to the shaft 22, and this pulley 43 drives the shaft 19 of the kicking roller 3A via a drive belt 44 and a pulley 45. Further, the pulley 42 is provided with a sensor operating plate 46, and on condition that the sensor operating plate 46 operates the photo sensor 47, the electromagnetic clutch 39 is opened and the shaft 22 is braked. By setting an electromagnetic brake (not shown) in a braking state, the feeding roller 21 is stopped at a certain position, that is, at a position where the friction feeding portion 23 can immediately come into contact with the lower surface of the banknote, as shown in FIG.

Furthermore, a gear 48 that drives the shaft 27 of the belt roller 26 is configured to mesh with the gear 37 of the shaft 38 .

Next, the operation of the feeding device configured as described above will be explained.

First, when a withdrawal command is given to the device, the electromagnetic brake is released and the electromagnetic clutch 39 is turned on, causing the rotation of the drive shaft 33 to stop at the shaft 1.
9 and 22, the kicking roller 3A rotates and sends out the bill 2 on the placement plate 17 in the direction of the page while moving it up and down. Then, the feeding roller 2
The friction feeding unit 23 of the banknote 2 that is fed out
When the banknote 2 is brought into contact with the lower surface of the banknote 2 and pulled out by the frictional force, the banknote 2 curves along the outer periphery of the feedout roller 21 while passing between the friction member 8 and the feedout roller 21 .

When the feeding roller 21 rotates approximately 1/4 turn,
The leading edge of the bill 2 is bitten between the first belt roller 25 and the belt 29 and is conveyed along the belt roller 25 while being curved. Since the radius R ₁ of the belt roller 25 is smaller than the radius R ₂ of the feeding roller 21 , the bill 2 being conveyed between the belt roller 25 and the belt 29 is not pressed toward the friction feeding portion 23 . Therefore, the frictional force with the frictional feeding portion 23 is maintained in the same manner as in the initial state of feeding.

When the feeding roller 21 further rotates, the banknote 2 is fed out from between the belt roller 25 and the belt 29, and is conveyed downward through between the belt 29 and the guide plates 30 and 31. sent between.

Note that the friction feeding portion 23 is connected to the feeding roller 2.
1, the next bill will not be dispensed until the friction dispensing unit 23 that dispensed one bill 2 returns to the position shown in FIG. A gap is created between the banknotes conveyed through the banknotes 14.

After feeding out a predetermined number of banknotes 2, the electromagnetic clutch 39 is turned OFF and the shaft 22 is moved to the shaft 3.
Further, when the sensor actuating plate 46 activates the photo sensor 47, the shaft 22 is braked by an electromagnetic brake (not shown) to stop the feeding roller 21 in the posture shown in FIG. , the preparation for the next banknote feeding is completed.

[Other embodiments of the invention]

(b) The section in which banknotes are held between the belt roller and the belt is not limited to the one described in the above embodiment. The winding angle of the belt may be increased.

(b) In the embodiment described above, the feeding device of the present invention is provided in the 1,000-note box, the 5,000-note box, and the 10,000-note box, but it may also be applied to paying out banknotes in a transaction outlet mechanism or the like.

(c) Due to the relative relationship between the banknote stacking section and the conveyance mechanism,
The second belt roller may be omitted, or the position of the idle roller may be changed to change the running path of the belt.

[Effect of idea]

As is clear from the above description, the present invention has the following effects.

The banknotes are held in the curved conveyance path between the belt roller whose outer diameter is small by the thickness of the banknote and the belt wound around the belt roller. Even when the banknote is in position, a certain contact pressure can be applied between the banknote and the banknote, and as a result, a predetermined frictional resistance is generated between the two, and the feeding force applied to the banknote is maintained. It is possible to prevent transportation troubles such as sagging and skewed feeding.

Furthermore, since the belt roller is rotatable relative to the feeding roller, it is not restricted by the rotation of the feeding roller and can rotate at high speed, for example, in synchronization with the belt conveyance system inside the machine.
Separation can be promoted by applying a force to the banknote in the direction of the paper surface.

Furthermore, the first belt not only functions to promote separation of banknotes by the feeding mechanism, but also functions to promote separation of banknotes by the feeding mechanism.
Since it forms part of the banknote conveyance means in the machine together with the belt, separation of accumulated banknotes ~ promotion of separation ~
It also has the effect of simplifying and downsizing the function that performs a series of transport functions, thereby contributing to securing space inside the aircraft.
