DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paper feeder that feeds out the foremost paper sheets one by one in a group of paper sheets that are arranged and stored one by one by a selective touch.

[Technical background of the invention and PR 4 points] Conventionally, in order to perform argumentation, identification, dispensing, and other types of processing of paper sheets such as banknotes, one sheet from a group of paper sheets that are arranged and stored in a row is used. 11 As a device, generally a P' rubbing roller is brought into contact with the surface of the sheet in front of R,
This F! (f) The scraping roller is fed out one by one by each rotation (j).

However, if the paper is fed out using a friction roller as described above, the paper 'I? The contact area with ii is a line contact, so if it is a new banknote, it will have a certain surface texture and will not cause much trouble. If the thread is uneven, it will easily slip and the feeding will become unstable. ) If it is necessary to feed the paper at regular intervals, the intervals will be uneven, which will cause problems in post-processing.

For this reason, conventionally, in order to provide a feeding device that needs to perform reliable feeding, a suction head is used to attract and separate paper sheets one by one, and after separation, the paper sheets are fed out by a feeding means.

However, in the DL using the above-mentioned suction head, it is necessary to make the suction and gutter oscillate in order to separate the paper sheets after adsorbing them to the suction surface of the suction head. Part 4. Not only does the i14 construction become significantly more complex, but also the vacuum pump and the 1lj related to the vacuum pump.
i1. There are many auxiliary equipment for piping and switching.

The problem is that it becomes expensive. In addition, with the suction head described above, the vinegar swinging movement of the gutter and the switching operation of the switching 4F to create a vacuum state inevitably intervene in suction, so there is a disadvantage that there is a limit to the speed at which paper sheets can be taken out >Xh. There is.

A posture holding means 8 for holding the belt 7 in a predetermined posture is provided below the endless belt 7, and in the illustrated embodiment, this posture holding device f9g is attached to the endless belt l-7 in the direction of the arrow. This figure shows a case in which it also serves as a vibration imparting means for imparting vibration.

That is, the posture holding means 8 includes a pulley 10 located between the rotary body 5 and an intermediate rotary body 9 mounted on an axis at a distance from the rotary body 5 and bringing the endless belt 7 into contact with the intermediate rotary body 9.
It consists of a drive pulley 11 which is pivoted on the lower part near the rear end of the free deformation portion 7A of the endless belt 7, and a belt 12 which is wrapped around these pulleys 10 and 11. The lower surface of the belt 7 is brought into pressure contact with the upper surface of the belt 12, and this pressure contact causes the free deformation portion 7A to move as shown by the chain line in FIG. It is designed to maintain the position where it should bulge upwards from the top surface of the bottom plate 2, as shown in the figure.
By driving the drive pulley 11 in the direction of the arrow, the endless belt 7 is moved in the direction of the arrow.

At the upper part of the feed opening 3, there is a gate forming part 14 that forms a gate part 13 that allows one sheet of paper P to pass between it and the outer surface of the endless belt 7 wound around the rotating body 5. is provided.

This gate member 14 may have a normal perfect circular roller structure, but in the illustrated embodiment p: (91
As shown enlarged in FIG. The concave arcuate surface 140 coincides with the 2 beams, and this concave arcuate surface 1
．． The entrance of the gate gap G is 1lJi between the circumferential end portion 14D of the large diameter portion 14B connected to the 40 and the outer circumferential surface of the endless belt 7.
A gate gap G is formed between the concave arc shape J4C and the belt 7 shown in ^1f.

When the peripheral end portion 14D of the large diameter portion 1413 is worn out and the entrance rl of the gate gap G is enlarged, the gate forming portion 14 is rotated a few thousand turns in the direction of the arrow to create a new one. The terminal end portion 14D faces the outer surface 1i1 of the endless belt 7, and a gate entrance gap of 1.5 mm is formed.

As a means for rotating this gate forming member J4, as shown in FIG.
Attach the worm foil 16 to 5, and attach the worm 17 to this.
A knob 19 is provided on the shaft 8 of the worm 17, and by rotating this knob 19, the gate forming member 14 is slightly rotated, and the gate forming member 14 is fixed with a screw or the like. A means to obtain t2 is provided.

On the downstream side of the gate section 13, at a predetermined position where the PIji is lowered, there are a pair of upper and lower rollers 20, 20, which are axially mounted at symmetrical positions on the left and right sides, and which grip and convey the fed-out paper 'gP.
, 21, 21 is provided.

In the figure, 23 is the lower end of the front #lA of the paper storage section 1.
a) Guide plate formed in a long shape and guiding the top surface of the paper IP;
A guide plate 24 is provided following the front end of the bottom plate 2 and guides the lower surface of the paper sheets P, and a guide plate 25 is placed on the upper surface of the two groups of paper sheets stacked in the paper sheet storage section 1. the end belt 7
Illustrated Fi! This is a suppressing member that applies pressure to keep it in the illustrated state.

In the above embodiment, when the paper sheets P are fed out intermittently at regular intervals D1, the rollers 2 (1, 20, 21, 21 constituting the conveyance means 22) are driven. The endless belt 7 is configured to be driven at a faster speed than the belting speed of the endless belt 7.

The effect will be explained below with reference to m51YI(A1-(force).

2115 As shown in FIG. 2115 (A), a large number of paper sheets P are arranged and stored in a stacked state in the paper sheet storage section 1, and a suppressing member 25 is placed on the top surface.
The sheet is placed (r) and pressurized. As a result, the free deformation portion 7A, which bulges upwards of the endless belt 7 and protrudes upward from within the notch 4 of the bottom plate 2, is pushed by the lower surface of the foremost paper sheet P. It is placed in close contact with the lower surface of the paper sheet P.

When the driving pjb pulley 11 is rotated in the direction of the arrow based on the ejection command, the pulley 10 and the belt I2 are both rotated in the direction of the arrow (111), and this pulley 10 portion is rotated between the intermediate rotating body 9 and the belt I2. Since the endless belt 7 is sandwiched, the rotating body 5 and the intermediate rotating body 9 are rotated 1D and 1 in the direction of the arrow via the endless belt 7, and the rear end of the part of the endless belt wound around the rotating body 5 is Since the side (Fig. 5 (Al position 71) is pulled, the free deformation region 7A is as shown in Fig. 5 (A
The robot is placed in the direction of the arrow v) in the posture shown in l.

When the endless belt 7 moves in the direction of the arrow as in the case of Toki, the foremost paper sheet P that is in surface contact with the top surface of the free deformation section (ff7A) is pushed out to the left in the door 1 due to the contact friction. The gate portion 13 stops the sheets P of 2A+, 1 to F;

When the tip of this fed-out paper sheet P is caught between the rollers 20 and 2 of the conveying means 22 as shown in FIG. 5,
Since the driving speed of this conveying means 22 is faster than the belting speed of the endless belt 7, the paper sheet P is pulled from the moment it is gripped, and the rear lower surface of the fed paper sheet P touches the endless belt 7. Because they are pressed together, the friction between them causes the endless belt 7 to be pulled together, as shown in Figure 5 (01).
A slack 7B is formed on the front side of the rotating body 5 as shown in )4
(It follows the progress of the empty paper sheet P. At this time, the rotating body 5 is also rotating at the same speed as the endless belt 7.

As a result, when the last 17 sheets of paper P finish passing through the gate part 13, when the paper sheet P is pulled out from under the heavily operated sheet, or when the last sheet is the last sheet, the sheet is pulled out from under the suppressing member 25. When exiting, the free deformation portion 7B approaches the intermediate rotating body 9 as shown in FIG. 5fD), and the slack 7B reaches its maximum.

At this time, the trailing end of the sheet P is pulled out from the gate section 13 and sent to the downstream side by the IB loading means 22, while the trailing end of the sheet P is sent to the downstream side by the IB loading means 22, while the t-tension holding means as shown in FIG. 5(E) 8σ] Due to the drive of the drive pulley, the lower half of the non-glued 1 pal door is divided by Y
i! I building, as shown in the diagram to eliminate sagging 7'f3.
The upper half part, that is, the lower part of the frontmost sheet P in the storage section 1, does not move and is placed stationary in the folded position. In other words, the rotating body 5 is in the state of Al.
The 101 rotation is stopped between the figure (F8) and (F).

At this time, at 4t+, l, the previously fed paper sheet P is ready to be sent to the downstream side by the 0 feeder ■length 22, and the next feeding paper 1'hi paper 'JJP is in the grip position. becomes.

When the state shown in Fig. ε105 (I"l) is restored, the upper half of the non-contact belt 7 starts moving in the direction of the arrow again due to the rotation of the attitude holding means 8, and the next sheet is placed on the upper surface thereof. The leaves P are bound and put out, and the same action is repeated thereafter to carry out the 11th turn.

+J-J+', -I;≠By appropriately selecting the station square 1 supplement of 壬IW99, the feeding interval of paper sheets P can be arbitrarily selected, and after feeding one sheet of paper P, Since the upper half of the endless belt 7 remains stationary until the next sheet P is fed, intermittent feeding is ensured.

In the illustrated embodiment, the paper sheets P are stacked and stored, and the paper sheets P are fed out sequentially starting from the lowest one. For example, the paper sheet P at the forefront is fed out downward or upward.
The feeding direction is not restricted and can be selected as appropriate depending on the application. In the illustrated embodiment,
Although the case is shown in which the posture holding means 8 also serves as the belt motion imparting means for the endless belt 7, the posture holding means 8 has a suppressing function of simply displacing the free deformation portion 7A of the endless belt 7 toward the sheet P side. Alternatively, a driving TJd) roller may be pressed against a portion corresponding to the rotating body 50 fV1 or the intermediate rotating body 9, so that the endless belt 7 can be kept in motion. Further, the suppressing member 25 is not limited to a plate shape, and may be a suppressing roller, and may be configured to press as It1' of the stacked Jtt leaves decreases. Furthermore, the configuration of the gate part J3, the conveyance means 22, etc. is also shown in the diagram lK11.
The present invention is not limited to this example, and design changes may be made at will without departing from the technical idea of the present invention.
