Abstract

PURPOSE:To certainly separate a paper sheet even if there are differences in size of paper sheets thrown into a hopper or the lower ends of paper sheets are not registered properly by quickening drive of a pickup roller which sends out paper sheets and amending improper registration of said ends. CONSTITUTION:The position of the tip Q1 of a friction member 4c of a feed roller 4 is set behind the engagement point of a gate roller 7 with the feed roller 4 by a distance corresponding to the dimcusion (m) of a paper sheet thrown in. When a tip part P1 of a convex part 5a of a roller 5 fitted on a shaft 4a of the feed roller 4 comes in contact with a roller 3, a pickup roller 2 starts to move and a group of paper sheets is sent out downward, then the friction member 4c of the feed roller 4 is sent out to its engagement part with the gate roller 7 with a phase lag (m). Accordingly, the lower ends of papers can be properly registered through quickly driving a friction member 2a of the pickup roller 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to, for example, self-help cash dispensing machines, automatic teller machines,
From the group of banknotes deposited in the hopper, such as the banknote banknote/spinning currency exchanger, -A money payer dispensing machine, etc., remove the first one.
This relates to a low-discharge minato-kei, which is separated into pieces and put out.

Figures 1 and 2 show the configuration of a conventional paper feeder. In the figures, 1 is a hopper in which the banknotes M that have been inserted are stored in a three-dimensional dogfighter. Front plate 1a, @i! The push plate 1b1.゛Plate IC
. 4Vk is provided for sending out the signal.

Further, a long hole 1d is bored slightly below the center of the front plate 1a of the hopper 1, extending in the hawk direction.
Paper f in hopper 1 is shown in d! Banknote M at the front of f-detail
All the above, pink up mouth that must be sent to htn - LA 2
is facing, and if the cylindrical surface of this pickup roller 2 is surrounded, it will be made of rubber or the like: I! A rubbing member 2a is attached to the east over the entire width, and is attached to the banknote M at the front end of @Fuyo. 4 is the lower part 1 of the hopper 1 (a) (close to the gap provided, and is rotatably supported on the machine frame so as to be horizontally oriented to the left and right, regardless of the bending line of one banknote). @4
Each feed roller 4 has a concave groove 4b over the entire length, and friction members 4C such as rubber of a required length are attached to the large diameter portions on both sides of the register 4b. The friction member 40 scrapes out the banknotes M. The shaft 4a of this feed roller 4 is driven by an electric fIJJ machine via a clutch and brake. The rotation of this feed roller 4 [11] 4a is
It is transmitted to the pickup roller 2 via the rubber roller 3 from the row 25 where the convex @sa integrated with the a-shaped part is visible. Reference numeral 7 denotes gate rollers disposed facing the corridor 4b of the feed roller 4. These gate rollers 7 are made of a material with a large friction coefficient and are supported by L14tI7a. Only the banknotes M in the trowel section pulled out by the pickup roller 2 are transferred to the feed roller 4 and the gate roller 7! / feed it to the conveyor belt 11. 8 is almost an enclosure with respect to the center box 1 extending in the transverse direction of the paper stack, and these pair of feed rollers 4
The valley stopper lawn 8 has a concave groove 8a over the entire 1ff, and the large diameter portions on both sides of this concave groove 8a are formed with grooves with small moorings. has been done. Reference numeral 12 denotes a gate roller disposed opposite to the recess tlsa of the stopper roller 8, and this gate roller 12 is molded from the same material as the gate roller 7. These pair of stopper rollers 8 and gate rollers 12 act as blades to block the force on the paper 1 to correct the skew of one banknote.

Due to the rotation of the pickup roller 2, there is a gap between the feed roller 4 and the gate roller 7! When M is pressed, if there is only one bill, it will be fed out by the feed roller 4, but if two banknotes are fed in, the feed roller 411! I's banknotes are transported, but gate row 2
The low pay of 711111 is because the shaft 7a of the gate row 27 is stationary, so no conveying force is generated and shearing force is generated between each banknote to separate the banknotes.

Reference numeral 9 represents a spring that provides a force for pressing the bill M against the pickup row 22, and 10 represents a guide shaft of the push plate 1b that is moved by this spring.

Next, the friction member 2 of the pickup roller 2 that pushes out the low feed
A, and the drive of the friction member 4C of the feed roller 4, which feeds one sheet of banknotes, are driven by the first
Matches as shown in the figure. In other words, at the 1II4a end! At the same time, when the tip P1 of the convex portion 5a tries to rotate the pickup roller 2 via the rubber roller 3,
The tip Q1 of the friction member 4C of the feed roller 4, which is attached to the convex portion 5a and the same axis 4, has reached a line connecting the centers of the gate roller 7 and the feed roller 4 with a straight line.

Regarding the relationship between the friction members of each of the pickup roller 2 and the feed roller 4 as described above.

As shown in FIG. 3, when several banknotes of different sizes are input with their bottoms and ends aligned, the friction member 2a of the pickup roller 2 (not shown) feeds the banknotes to the friction member of the feed roller 4. As shown by M+, Mt 1Ms 9Ma in FIG. 4, only the banknotes that come in contact with the friction member 4C of the feed roller 4 are fed into the separation part between the gate row 27 and the gate row 27, and stable general feeding is carried out at a constant cycle. It is possible. However, for example, as shown in FIG. 5, if several gold single-layer bills with different paper leaf sizes are thrown in without being drained.

Compared to when the bottom and bottom sides are aligned and the banknote cycle is checked one by one, the banknote cycle becomes unstable due to the uneven dimensions, as shown in Figure 6, or becomes L2. It's easy to become something.

If such unstable synchronization occurs, it becomes a factor that the recognition rate for each denomination deteriorates in the banknote storage section provided after the banknote separation.

Also, in wiping the bottom edge of such banknotes unevenly.

When the pick-up row 22 rotates as shown in FIG. 1 paper Nf M
o Because the friction force between the banknote Mlo and the banknote Mlo is large, there may be cases where no gap is generated between the first paper layer M and the banknote Mlo, or despite the feeding operation of the pickup roller 2, the banknote
The movement of the paper money M is accelerated, and as shown in the dog state shown in FIG. When it reaches the L separation section, this Gion Mo 9M+o cannot be separated one by one and multiple transfers occur.The latter type of - hand is often the face-down type.In other words, in this case, Banknote MI0 is M,
Since the feed roller 4 contacts the feed roller 4 and passes through the separation section earlier than the feed roller 4, only the conveyance force from the pickup roller and the feed roller acts on the low feed M on the front upper surface of the feed roller 4, and the separation by the gate roller 7 is performed. Force no longer acts. This bundling and multiple feeding will occur frequently.

In view of the above-mentioned points, the present invention has been developed by blowing out the frontmost paper sheet from among several mixed paper sheets of various sizes stored in the hopper in an upright position. The object of the present invention is to provide a delivery device which corrects the lower dimension even if the paper size difference is only one difference in size, and even in a feeding state where it is easy to tear, the lower dimension is corrected and the paper is delivered in increments of Ic1i. .

The special feature of the present invention is that in the paper sheet delivery device in the hopper that separates and conveys the paper sheets one by one, the timing for sending the paper sheets to the separation means by the rotation of the pickup roller is set by one separation means. The timing is set to be approximately seven paper sheets earlier than the timing at which the conveying force is applied to the paper sheets by the rubbing member disposed on the feed roller.

Hereinafter, the paper sheet feeding device of the present invention will be explained in detail with reference to cash self-help payments.

Items shown in Figure 8 that are fake and have the same numerals as those in Figure 1 indicate the same parts. The low feed at the forefront is reduced by pressing the standing position of the hopper directly behind the hopper 1 onto the front rack 1a using the push plate 1b.
strongly pressed against.

Feed roller 4 that pivots due to the stable movement 1 $ 34
The rotation of a is transmitted to the pickup roller 2 via the rubber roller 3 from a roller 5 having a convex portion 5a integrally attached to the front 4a4. This rotation of the pickup row 22 is carried out while the convex portion 5a of the roller 5 is in contact with the rubber roller 3.
Pull away from.

Pull out the pickup roller 2 downward. A friction member 2a made of, for example, rubber is disposed on the circumferential surface of the pickup roller 2, avoiding the four-fold and three-fold squares of the banknote. Even if the banknotes are sharpened, the scraping member 2a is attached to the straight part without the first loaf, so it is possible to feed out the banknotes without any crooked edges, just like in the case of feeding out banknotes with no edges.

Subsequently, the frontmost banknote pulled out downward by the rotation of the pickup row 22 is generally fed downward by the friction member 4C of the feed row 24 and is caught between the feed roller 4 and the gate row 27. It will be done. Here, the u-support timing of the friction member 2a of the pickup row 22 that feeds the banknotes and the friction member 4C of the feed roller 4 (9) are set as shown in Fig. *49. That is, when the tip P1 of the convex portion 5a of the row 25, which has been given the "faf-" function of 1114, comes into contact with the row 23, the pickup roller 2 starts to move.

At this time, the tip of the friction member 4C of the feed roller 4, M
The position of tQl is set to be delayed from the joining point of the gate roller 7 and the feed roller 4 by a distance corresponding to the dimensional difference m of the stacks of paper to be fed. As a result.

The group of banknotes is first sent downward by the pick-up roller 2, and at a position m d from n, the friction member 4C of the feed roller 4 moves the banknote to the engagement portion with the gate roller 7 (((is sent out. Therefore, even if banknotes of different sizes are thrown into the hopper IK with irregularities, the friction member 2a of the pickup roller 2 quickly disturbs the lower part of the banknotes.

The bill is connected to the friction member 4a of the feed roller 4 and the gate row 2.
When the number 7 goes down, it can be used as a sign that the bottom end of one banknote has fallen. As a result, even if banknotes of different sizes are inserted irregularly, it is possible to send out one banknote at a constant cycle (10), even if the banknotes are irregularly inserted.

At this time, for example, if the banknotes stored in the hopper 1 are obliquely oblique or have been obliquely pulled out by the pickup roller 2.

Around that time, the edge of the banknote that has been compacted is caught between the stopper roller 8 and the gate roller 12, but the stopper roller 8 and the gate roller 12
Because the coefficient of friction is larger.

The tilted banknotes are temporarily blocked from general transportation. That wheat 1
When the oblique angle of the paper is corrected and straightened, the banknote is caught between the feed roller 4 and the gate roller 7 as described above, and a conveying force is generated until the bond between the feed roller 4 and the conveyor belt 11 is reached. When it arrives, it is grabbed by a conveyor belt and conveyed backwards.

In addition, if the bills pulled downward by the pickup roller 2 are two stacked bills, the second bill is stopped and conveyed by the o-rough; Only the banknotes are caught between the feed roller 4 and the gate row 27 and are generally fed.

(11) When the frontmost banknote feeding operation is finished, the shaft 4a of the feed roller 4, the convex portion 5a on the D roller 5, and the rubber roller 3 start coming into contact with each other, and the pickup roller 20 times=
The next banknote is then pulled out downward, and then the feed roller 4 and gate roller 7 are used to pull out the next banknote.

In the above, we have described the configuration of the feed roller and gate mechanism in sequence, including the roller having a groove in the circle and the alignment of the roller arranged so as to overlap with the roller. It is also possible to use a type in which the rollers press against each other, or a type in which the gate roller is a fixed rubbing member. In addition, in the case of a feed roller having a constricting member locally disposed on its circumference, the entire circumference of the feed roller is ≠ the vibrating portion.

By controlling the drive in a drowsy manner, it is possible to maintain a constant spacing between the sheets to be sent out, so essentially, as in the above-mentioned deer row, the front member can be locally moved. The result is the same as when using the provided rollers. It is clear that the present invention can be applied to a separation mechanism that utilizes the frictional force of rollers (12), but it is also possible to replace the part corresponding to the feed roller with a vacuum rotating drum having suction pieces. Needless to say, it is possible to exercise the functions of consciousness.

On the other hand, in the above-mentioned penance procession, although each part was targeted at banknotes, the target is not only banknotes but also a device that inputs a mixture of forms of different sizes and separates and conveys them. Needless to say, it can also be applied.

According to the present invention, even if the sizes of sheets input into the hopper are different and the lower edges of each sheet are uneven in the conveyance direction, the pickup roller that feeds one sheet can be driven quickly. By doing so, you will be able to correct these imperfections.

With conventional separation mechanisms, the synchronization between each sheet was unstable9
However, it was not possible to achieve highly reliable paper sheet separation due to the occurrence of multiple feeds, but it is now possible to solve these problems in the conventional method and achieve highly reliable sheet separation. .
