The present invention relates to a paper sheet separating and feeding device which is assembled into an automatic teller machine or an optical reader, and includes a plurality of rollers that rotate paper sheets such as bills or papers stored in the storage unit so that the feeding directions are different from each other. It relates to a paper sheet separating and feeding device for dispensing, feeding and feeding one by one by cooperation.

FIG. 4 is a perspective view showing a conventional paper sheet separating and feeding device of this type, FIG. 5 is a side view of FIG. The stage 3 is possible.

4 is a paper sheet accommodated in the accommodating part 1 in the shape accumulated on this stage 3.

5 has a high friction member 6 on a part of the outer circumference as a pickup roller, and two pickup rollers 5 are fixed to the shaft 7 at predetermined intervals and are arranged on the paper leaf 4.

8 is a feed roller, which has a high friction member 9 at the outer peripheral part like the pickup roller 5, and two ring-shaped grooves 10 are provided along the entire circumferential direction.

This feed roller 8 is fixed to the shaft 11 provided in parallel with the shaft 7 at two predetermined intervals and is located on the guide plate portion 2.

12 is a separation roller and has one ring-shaped groove 13 throughout the circumferential direction.

The separation roller 12 is attached to the shaft 15 held in a rotatable manner to the retaining block 14 positioned below the guide plate portion 2 so as to have the same distance as the feed roller 8, and thus the guide plate portion. In the drilled hole provided in (2), a part of the outer periphery protrudes on the upper surface side and is slightly engaged with each other by the feed roller 8 and the grooves 10 and 13 of each other.

16 and 17 are pulleys attached to one end of the shafts 7 and 11 respectively, 18 is a motor, 19 is a drive pulley attached to the rotating shaft of the corresponding motor 18, 20 is the pulley 16 and 17 and the drive pulley 19 When the motor 18 is rotated in a predetermined direction as a locked belt, the rotational force is transmitted to the pulleys 16 and 17 via the driving pulley 19 and the belt 20, thereby respectively providing a shaft 7. The same speed as the pickup roller 5 and the feed roller 8 in the same direction as indicated by the arrow a. It rotates as a figure.

Further, the stage 3 of the housing portion 1 has a force applied upward by a spring or a driving mechanism (not shown), whereby the stage 3 is raised so that the uppermost leaf 4 is picked up by the pickup roller 5. It is pressed and is folded.

In addition, the high friction members 6 and 9 provided in the pickup roller 5 and the feed roller are repeatedly fed to the sheet 4 and have sufficient frictional force for feeding.

Again, a one-way clutch (not shown) is installed between the feed roller 8 and the separation roller 12 and the shaft 15 engaged with each other, as shown by arrow (b) by a motor (not shown). (4) is rotated only in the direction of pushing back to the receiving part 1 side, and the frictional force against the leaf 4 of the separation roller 12 is the frictional force against the leaf 4 of the feed roller 8. It is set smaller than.

The operation of the above-described configuration is as follows.

As shown in FIG. 4, the motor 18 is driven by a signal from a controller (not shown) in the state where the uppermost leaf 4 on the stage 3 is pressed against the pickup roller 5 and is in contact with it. Is rotated, the rotational force is transmitted to the pulleys 16 and 17 via the driving pulley 19 and the belt 20, respectively, as described above, whereby the pick-up roller 5 is integral with the shafts 7 and 11. ) And the feed roller 8 are circulated in the direction of the arrow a.

At this time, the separation roller 12 also rotates in the direction of the arrow b by a motor or the like (not shown).

Wherein the upper leaf (4) is rotated forward by the frictional force with the high friction member 6 is installed on the outer circumference when the pickup roller (5) is rotated so that the front end of the feed roller and the separation roller (12) The direction of the arrow c is applied by the frictional force with the high friction member 9 which is fitted between the high roller and the outer peripheral part by rotation of the feed roller 8 again.

At this time, the paper leaf 4 is applied to the paper sheet 4 of the separating roller 12 by a force that is pushed back to the receiving part 1 side by the separating roller 12 rotating in the direction of the arrow b. Since the frictional force is smaller than the frictional force against the sheet 4 of the high friction member 9, the sheet 4 is sent in the direction of the arrow c along the guide plate 2 with the rotation of the feed roller 8. Goes.

By the way, the paper leaf 4 repeatedly disbursed by the rotation of the pickup roller 5 is not limited to only the top one, but the paper leaves 4 are in close contact with each other by various factors. A plurality of sheets may be sent out in a state where 4) is overlapped.

In this case, the separation roller 12 is slightly engaged with the feed roller 8, and the separation roller 12 is always rotated in the direction of the arrow b, that is, the paper roll 4 is pushed back to the housing 1, The paper sheets 4 other than the topmost ones are stopped by the separating rollers 12, and only the topmost papers 4 which are in direct contact with the topmost feed roller 8 are sent in the direction of the arrow c.

Accordingly, the paper sheets 4 are separated and fed one by one from the storage unit 1, and the fed paper sheets 4 are conveyed again to a predetermined load by a conveying path made of a roller, a belt, or the like (not shown).

However, according to the conventional technique described above, if the bent or bent jaw is attached to the paper lodged stored in the storage unit, or if the stage on which the paper lodges 4 are stacked is inclined, the top of the paper folded to the pickup roller is inclined. Due to the difference in the vertical drag between the ground rollers and the pickup rollers, the frictional force between the ground rollers and the pickup rollers causes the grounds to meander, resulting in the repetitive expenditure of such grounds. In other words, there has been a problem that a problem such as a jam due to the meander occurs due to a problem in the subsequent processing of the sheet or during feeding to the processing site.

The present invention has been made to solve the above problems, and even if the top surface of the paper sheet is inclined, the paper feed is separated and fed without causing a difference in friction force between the paper sheet and the pickup roller without feeding the paper sheet. The purpose is to realize the device.

In order to achieve the elevated purpose, the present invention attaches one end of the bracket to the predetermined position of the shaft of the feed roller so as to be rotatable, and at the other end of the pickup roller to be inclined in the vertical direction with respect to the shaft of the feed roller. The shaft is attached through the bearing and the pulleys are attached to each of the shafts of the feed rollers and the pickup rollers, respectively, so that the rotational force of the motor is transmitted from the shafts of the feed rollers to the shafts of the pickup rollers. It is.

According to the above-described configuration, if the top surface of the paper sheet is inclined due to various factors such as a trace of a bent curve in the paper sheet or the stage on which the paper sheets are stacked, when the paper sheet is repeatedly fed and fed, the bracket and The shaft of the pickup roller is inclined so as to be parallel with the top surface of the inclined lobe by means of the bearing installed at the other end of the bracket, whereby the pick up roller can always be pressed vertically against the lobe, so as to pick up the lobe. The vertical force of the roller acts uniformly.

Because of this, the pick-up roller is pressed against the paper leaf with uniform frictional force, so that even if the top surface of the paper leaf is inclined, it is not meandered and repeated spending by various factors, thereby eliminating jams after repeated feeding and feeding. It will not interfere with the processing of subsequent sheets.

The simple structure of the bracket and the bearings which can be inclined in the vertical direction can provide a cheap and reliable paper sheet feeding and feeding device.

EXAMPLE

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 is a perspective view showing an embodiment of the paper sheet separating feeding device of the present invention, FIG. 2 is a front view of the main part of FIG. 1, and FIG. 3 is a side view of the main part of FIG. 1, in which 1 is an accommodating part and 2 is a guide. Plate part, 3 is stage, 4 is lobe, 5 is pickup roller, 6 is high friction member, 7 is shaft, 8 is feed roller, 9 is high friction member, 10 is groove, 11 is shaft, 12 is separation roller, 13 Silver groove, 14 is a retaining block, 15 is a shaft, 17 is a pulley, 18 is a motor, 19 is a driving pulley and 20 is a belt. These are equivalent to those of Figs. In this case, only the pulley 17 of one end of the shaft 11 is wound around the drive pulley 19 and the belt 20 of the motor 18 so as to obtain rotational force from the motor 18. have.

21 is a pulley attached to one end of the shaft 7, 22 is a pulley same as the corresponding pulley 21 attached to the shaft 11 so as to correspond to the pulley 21, 23 is both pulleys 21 and 22. When the motor 18 is rotated as a belt wound in a predetermined direction, the rotational force is transmitted to the pulley 17 via the driving pulley 19 and the belt 20, thereby integrating with the shaft 11. The low feed roller 8 and the pulley 21 rotate, and the rotational force is transmitted to the pulley 22 via the belt 23 from the rotating pulley 21, whereby the pick-up roller is integral with the shaft 7. (5) is made to rotate.

At this time, the pulleys 21 and 22 are each rotated at the same rotational speed, whereby the pickup roller 5 and the feed roller 8 are in the same direction as the arrow (a). 4) is rotated at the same speed in the direction of feeding in the storage section (1).

24 is a pair of brackets for supporting the shaft 7 and the bracket 24 has a protruding edge 24a protruding from the rear side, and through the bearing 25 so that the shaft 11 can be freely rotated. One end of the shaft 11 is rotatably attached so as to face the outer side of the feed roller 8 of the shaft 11 and the shaft 7 rotates the shaft 7 via the automatic center adjustment bearing 26 at the other end. This material is also attached to both outer sides of the pickup roller 5 so as to be able to move upward and downward with respect to the shaft 11 and incline a predetermined amount.

27 is a post, and the post 27 is formed by protruding inward from a flame or the like provided on both outer sides of the accommodating part 1, so that the protruding edge 24a is the post 27 when the bracket 24 is inclined. The angle of inclination of the bracket 24 is regulated by the contact with.

When the paper sheets 4 stacked on the storage unit 1 are to be fed by the above-described configuration, as shown in FIGS. 2 and 3, a bent or the like of the traces bent on the paper sheets 4 remains or leaves. According to the stage (3) for stacking (4) is inclined, if the uppermost surface of the paper sheets (4) stacked on the accommodating part 1 is inclined, the shaft (7) has both ends of the automatic center adjustment shaft support ( 26, the pickup roller 5 follows the uppermost surface of the leaflet 4 by tilting the shaft 7 at the same time as the top surface of the leaflet 4. Since the pick-up roller 5 is always vertically in contact with the paper leaf 4 by tilting it in parallel, the vertical drag force on the paper leaf 4 of the pick-up roller 5 acts uniformly. .

In this way, when the motor 18 is rotated by a signal from a controller (not shown) to repeatedly feed and feed the paper sheets 4 accumulated in the storage unit 1, the driving force of the driving pulley 19 is as described above. And the feed roller 8 and the pulley 21 are rotated integrally with the shaft 11 through the belt 20 and thereby the rotational force of the pulley 21 causes the belt 23 to rotate. It is transmitted to the pulley 17 through which the feed roller 8 and the pulley 21 are rotated integrally with the shaft 11, and the rotational force of the pulley 21 is transmitted to the pulley 22 via the belt 23. And thereby the pickup roller 5 rotates in the direction of the arrow a integrally with the shaft 7.

At this time, since the vertical drag on the lobe 4 of the pickup roller 5 is made uniform by the automatic center adjustment bearing 26 as described above, the lobe 4 has the uniform frictional force of the feed roller 8. It becomes possible to feed one by one accurately without generating meandering lights in the direction.

Then, the paper sheet 4 is fed in the same manner as in the conventional art.

As described above, according to the present invention, one end of the bracket is rotatably attached to the shaft of the feed roller, and the other end of the pick-up roller is attached to the shaft through the bearing so as to be inclined upward and downward with respect to the shaft of the feed roller. In addition, the pulleys are attached to both shafts, respectively, so that the belts are wound to the shafts of the pickup rollers of the motors.

For this reason, even if the top surface of the paper sheets 4 stacked on the stage of the storage unit is inclined due to various factors, the pick-up rollers are inclined at the same time as the pick-up rollers by the brackets and bearings, and the shafts are also inclined at the same time. As a result of uniform friction, the paper leaf can be repeatedly disbursed in the direction of the feed roller. Therefore, it is possible to feed the paper sheet to the part to be precisely processed one by one without meandering and repeatedly spending. It is possible to obtain the effect that the subsequent processing of the lobe is not disturbed without generating the odor.

In addition, since the simple structure is provided by simply mounting the bracket and the bearing which can be inclined in the vertical direction, it is possible to realize a paper sheet feeding and feeding device with low cost and high reliability.
