Abstract

PURPOSE:To prevent paper sheets from being overlappedly fed, by constituting a secondary gate for separating paper sheets from each other, with a pay-out belt and pressing rollers. CONSTITUTION:When shafts 1, 2 are rotated in response to a drive instruction, a kicker roller 30, a pay-out belt 16 and a roller 17 pay out paper sheets in an overlapped condition, but a secondary gate constituted by the pay-out belt 16 and pressing rollers 25 limits the number of overlapped sheets within a range of 10 to 15. These paper sheets are fed by the kicker roller 30 and the pay-out belt 16 in such a condition that they are pressed at both surfaces by the pressing roller 25, and therefore reach the gate gap formed by a feed roller 12 and a gate roller 20. At this time the lowermost paper sheet alone is paid out by the feed roller 12. Thus, paper sheets are separated and fed one by one without using a conventional pressing plate.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet feeding device that separates and feeds paper sheets that are arranged and stored one by one.

[Prior art and its problems]

Conventionally, various types of dispensing devices have been put into practical use that separate paper sheets stored in an aligned state one by one using a friction dispensing means, but in this type of friction dispensing means,
It is indispensable to provide a pressing plate as a pressing means for generating a predetermined frictional force toward the frictionally feeding means to direct the aligned and stored paper sheets toward the frictional feeding means. The pressing force from this pressing plate subtly influences the feeding of the frictional feeding means and influences the feeding situation.

In other words, in the friction feeding means, a gate gap is usually formed between a feed roller and a gate member, and a kicker roller kicks out the paper sheets and feeds them toward the gate gap, and only one sheet of paper sheets is fed in the gate gap. However, depending on the strength of the pressing force of the suppression play 1, two sheets of paper may be fed out at the same time, or so-called empty feeding may occur in which no leaves are fed out.

In this way, in the conventional feeding device, pressure play 1 to
This is an indispensable component, and because it has this pressure plate, the feeding of paper sheets becomes uncertain depending on the strength of the pressure force, which is contradictory.

In addition, since the conventional feeding device has the pressing brake 1~, each time when loading paper sheets into the storage section, the pressing brake 1~ is held in the returned state against the bias. The paper sheets had to be stored and arranged in an orderly manner, and the loading work was not easy.

[Purpose of the invention]

The present invention has been made with the aim of improving the above-mentioned problems of the prior art, and eliminates the suppression plays 1 to 1 to facilitate the loading work of paper sheets. It is an object of the present invention to provide a sheet feeding device which is capable of feeding a single sheet of paper more reliably compared to the prior art, even though it does not use .

[Summary of the invention]

In order to achieve the above object, the paper sheet feeding device according to the present invention separates the paper sheets stored in an aligned state one by one and feeds out the paper sheets by contacting the paper sheets in the feeding device. a feed roller that feeds the feed roller; a gate member that faces the feed roller and forms a gap between its peripheral surfaces to the goo 1;
a kicker roller for feeding paper sheets toward the gate gap; a first pulley provided on the support shaft of the feed roller; and a second pulley provided on the support shaft of the kicker roller. pulleys and the hook between these pulleys ('lI
A presser roller is provided at the end of a guide plate for regulating the front edge of the aligned and stored paper sheets in the feeding direction, and is brought into pressure contact with the feeding belt, and The bell 1~ and the presser roller constitute a secondary gate part for separating paper sheets, and the paper sheets passing through the secondary gate part are placed in the gap between the gates by one sheet. It is characterized by being able to be played out by

A shaft 6'', which is non-rotatably mounted on a shaft support arm (not shown), has a circular surface facing the feed roller 12. The protrusions 2OA and 2OA that fit into the grooves 12Δ and 12Δ are on the right, and there is a gap between the circumferential surfaces! - The rollers 1 to 20 are removed via a one-way latch (not shown) that forms a gap and can freely rotate in the opposite direction to the feeding direction of the paper sheet P, and the central part A pulley 21 is rotatably attached to the shaft 6.

A pulley 22.22 is fixed to the shaft end of @7, 7, and this pulley 22.22 and the pulley 19.1 on the shaft 5
Belt 23.23 is hung on 9 and 1, and this bell 1
~23.23 is the above bell h1 at the pulley 10° 10 position
A portion is brought into close contact with 4 and 14 and is pressed. Therefore, the belt 23.23 is driven to rotate through the belt 14°1/I.

A bell 1-24 is hung between the pulley 21 and the central pulley 18 on the shaft 5, and the belt 24 is brought into contact with the belt 14 at the central speed increasing pulley 10 position. As a result, the belt 24 is also driven to rotate through the belt 14. In this way, the belts 23, 23, 24 are driven to rotate at the same circumferential speed as the belt 14.

On the shaft 8, a presser roller 25.
25 is supported by its shaft 8 and support arms 25.DELTA., 25.DELTA. so as to be able to move up and down, and is urged downward by the weight of the presser roller 25.25 and pressed against the feeding belt 16.16.

On the other hand, at the upper part of the shafts 1, 2.3, the feeding belts 16, 16
, the bottom plate 26 is disposed below the upper surface of the belt 14, 14.1/l, and is located above the upper surface of the feed belt 16, 16, belt 14.14. A guide plate 27 extending toward the rear end is provided,
The presser roller 25.25 portion of the guide plate 27 rises at a vertical angle, and a part of the circumferential surface of the presser roller 25.25 protrudes from the cut holes 27A, 27A in the bent portion.

The feed roller 12.12 on the shaft 2 is made of urethane rubber or the like and has a friction surface on its entire circumference, and its outer circumferential surface is attached to the belt 1/'1. ．．
14. ．． 14 parts have the same diameter as the outer peripheral surface, and pulley 1
The outer peripheral surfaces of the belt 16 and 16, which are hung on the belt 1.11, have the same diameter.

Further, the hard roller 30.30 on the shaft 3'' is made of urethane rubber or the like and has a friction surface on its entire circumference, and its outer circumferential surface is attached to the feed belt 1 which is hung on the pulley 15.15.
6.16 The diameter is the same as the outer peripheral surface. Furthermore, axis 4”
The second roller 17.17 is also made of urethane rubber or the like and has a friction surface on its entire circumference.

Then, the shaft 2 is rotated by a stepping motor (not shown), so that the feed roller 12. roller 1
7 and 17 are rotated at the same peripheral speed v1. Note that the peripheral speed of the feed roller 12.degree. 12 is the peripheral speed 1 only when the feed roller 12.degree. 12 is not accelerated by the paper sheets P. The press rollers 25, 25, which are pressed against the above-mentioned feed belt 16.16 by their own weight, are also driven to rotate at a circumferential speed of 1. If the paper sheet is entering, the circumferential speed of the presser rollers 25, 25 follows the speed of the paper sheet that comes into contact with it)'? I-ru.

On the other hand, by rotating the shaft 1 with a reaction synchronous motor (not shown), the belts 14, 14.1
/1, belts 23, 23, bells 1 to 24 have circumferential speed ■1
It is rotated at a higher circumferential speed ■2.

The button head from the point of contact between the feeding belt 16, 16 and the presser roller 25, 25 to the rollers 17, 17 is set to a dimension one larger than the length of the sheet to be processed in the feeding direction. 12.12 gate roller 20
, 20 from the gate gap position formed by rollers 17, 1
The distance up to 7 is smaller than the length of the paper sheet to be processed in the feeding direction, and is a dimensional relationship in which the leading edge of the paper sheet enters the gate gap after the rear end of the paper sheet leaves the rollers 17, 17. is set to

Then, the stacked paper sheets are placed on the hard rollers 30 and 3 with their leading ends aligned with the rising portion of the guide plate 27.
0, put on the feed-out bell l 16.16 and on the roller 17.17. When shafts 1 and 2 are rotated by a drive command,
Hard roller 30°30, feeding belt 16, 16,
A large number of overlapping sheets are fed out by the roller 17°17, but the feeding bell 1-16, 16 and the presser roller 25
A secondary gate is formed by ゜25, and the paper sheets that have passed through the secondary gate 1 to 1 are limited to 10 to 15 sheets. The press rollers 25, 25 perform a suppressing action on the upper surface of the paper sheets (corresponding to the suppressing action of a conventional suppressing plate). After the leading edge of those paper sheets has passed through the secondary goo part 1~, the paper sheets are removed from the rollers 17, 17, and the paper sheets are held down from two sides by the press roller 25. 25, the kick roller 30, 301 and feed belt 16, 16 reach the gate gap formed by the feed roller 12, 12 and the gate rollers 20, 20. At that time, among the paper sheets Only the lowest paper sheet is fed out by the feed roller 12.12, and the leading edge of the paper sheet begins to pass through the gate gap, and is delivered to Bell 1 between 14.14.! and 23.23° to Bell 1. The tip of the paper sheet is held in the mouth.The M of the sheet is held between the belt 14.14..1/I and the belt 23°23.24.
The feeding speed of W type is feeding belt 16.16, hard roller 30.30. The speed V1 is equal to the circumferential speed ■1 of the rollers 17, 17, but the tip of the sheet is 1/1 of the belt.
．． ．． 14.14 and bell l-14, when held between bells 1-23°23.24.

14. The transport speed is increased to a conveying speed of ■2 equal to the circumferential speed of 14, ■2, and sent to the downstream side. At this time, the feed roller 12° 12 that contacts the paper sheet at the conveyance speed V2 is rotated at a circumferential speed v2 while in contact with the paper sheet, thereby assisting the conveyance of the conveyance sheet at the speed v2. . Note that the subsequent parts of the paper sheets conveyed at a circumferential speed of 2 are a feed belt 16, 16 and a hard roller 30, which are rotated at a circumferential speed of v1. , 30, but only a part of the weight of the stacked paper sheets (rollers 17, 17 and the rising portion of the guide plate 27 share and support a part of the weight of the stacked paper sheets) is the hard roller 30° 30 part. Presser roller 2 that also joins the feed-out bell 1-16.16
The pressing force of 5 and 25 is not so large because it is due to their own weight, so there is no large frictional contact, no friction damage to the paper sheets, and no influence on the feeding and conveyance.

Note that even if the amount of accumulated paper sheets decreases, the presser opening-ra 25
．． 25 also has a suppressing effect on the last sheet of paper, so that the next V also ensures that the leaf is fed into the gate gap. That is, since there is no suppressing means in the storage section, when the space between paper sheet storages decreases, there is no possibility that paper sheets will be fed out diagonally or that mistakes will occur frequently.

In addition, Bell l-14, 14, 14, Bell l-23.

23.2/l circumferential speed ■2 is fed out belt 16° 1G,
The reason why the circumferential speed of the hard rollers 30, 30, etc. is set higher than 1 is to ensure that there is a sufficient gap between the sheets being delivered and conveyed.

In addition to the hard rollers 30 and 30, rollers 17 and 17 are installed (the purpose of this is to have the role of free sharing of paper sheets, etc.).
This is to continuously send the accumulated paper sheets to the secondary group 1.

Next, the effect will be explained.

When the paper sheets P are stacked horizontally on the upper surface of the roller 17.17 from the hard roller 30.30 by an appropriate means and the start command button (not shown) is operated, the reaction synchronous motor is driven. The stepping motor is rotated to rotate the shaft 1, and the stepping motor is rotated to rotate the shaft 2. As a result, feed rollers 12, 12, feeding bells 1 to 16, 16, hard rollers 30, 30, roller 1
7.17 is the peripheral speed V1, and the belt 14-. 14°14.
23, 23, and 24 are driven at a circumferential speed of 2. Therefore, the lowest paper sheets and the paper sheets P in the upper layer are the hard rollers 30, 30. And due to the rotation of the feeding belts 1 to 16.16, they are shifted to the left in the figure in a large number of overlapping states, and a secondary gate section consisting of a presser roller 25° 25 and a feeding belt 16.16 10~ paper leaves
The stack of 150 to 15 sheets enters under the presser rollers 25, 25, and is fed out by the belt movement of the feeding bell 1-16.16. Thereafter, the presser rollers 25.degree. 25 act as pressing means for the 155 overlapping sheets that have passed through the secondary gate section.

The leading ends of these paper sheets enter the gate gap formed between the feed roller 12° 12 and the goo 1 to rollers 20, 20, and only one paper sheet is allowed to pass through this gate gap, Passage of two sheets stacked on top of each other is prevented.

A sheet of paper P is passed through the gate gap moving at a speed of V1.14. ．． 14 and bell 1~23.23
．． 24 and is conveyed at an increased speed of v2, and is discharged from between pulleys 9.9.9 and 19.degree. 19.19.

In this embodiment, the gate member is a roller that freely rotates only in the opposite direction, but it may be a roller that is forcibly driven in the reverse direction, or it may be a member that does not move, such as a fixed plate. .
