Description

[Detailed description of the invention] [Industrial field of application] The present invention is applicable to a paper sheet processing device such as an automatic teller machine or automatic teller machine, in which paper sheets stored in a storage section are sequentially processed one by one. This invention relates to a device for taking out paper sheets one by one.

[Conventional technology]

Conventionally, in this type of paper sheet take-out device, a group of paper sheets stored in a storage section is pressed against a take-out roller by a backup plate (back-up member), and the paper sheets are removed as the take-out roller rotates. The sheet is taken out from the accommodating portion and fed between a feed roller and a friction member for preventing multiple sheets from being taken, and as the feed roller rotates, the sheet is sequentially sent out one sheet at a time to a subsequent conveyance path.

However, the feed roller and the friction member are each fixed at a predetermined position. Therefore, for example, folded paper sheets, wrinkled paper sheets, etc. may become stuck between the feed roller and the friction member and become impossible to take out. If such a situation occurs, the paper sheets that cannot be removed should be removed by a person who has stored them in the storage unit, such as a customer, and the folds and wrinkles should be removed and the paper sheets placed in the storage unit again. The current situation is that they are being accommodated at However, if paper sheets become stuck between the fixed feed roller and the friction member, the contact pressure between the feed roller and the friction member against the paper sheets increases, making it difficult to remove the paper sheets, and furthermore, If the end side is pressed against the take-out roller by the backup plate, it becomes even more difficult to take out. For this reason, it is necessary to rely on the processing by an attendant, which has the problem of being troublesome.

Japanese Patent Application Laid-Open No. 53-91739 and Japanese Patent Application Laid-open No. 159967-1987 disclose methods that make it easier to remove this type of clogging.

[Problem that the invention attempts to solve]

However, the method disclosed in the former publication has the disadvantage that when the separation belt 7 separates from the feed roller 4, the trailing end of the sheet is pressed down by the protrusion 26, making it difficult to remove the jammed sheet.

Furthermore, the method disclosed in the latter publication requires a button operation to once separate the separation member 6 from the separation rotating body 5, and then a button operation again to lower the paper feed tray 1, which is a disadvantage that it is time-consuming. There is.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to have a relatively simple structure, but in the unlikely event that paper sheets become jammed between the feed roller and the friction member and cannot be taken out. When a paper sheet occurs, a feed roller can be retracted from the paper sheet, and a back-up member can also be retracted in conjunction with this, so that the paper sheet can be easily extracted. An object of the present invention is to provide a leaf extracting device.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention takes out paper sheets from a storage unit that stores multiple sheets at once as a take-out roller rotates, and connects a feed roller and a mechanism to prevent multiple sheets from being taken. In the device for taking out paper sheets, the paper sheet is fed between the paper sheet and the friction member, and is separated and sent out one by one as the feed roller rotates, in which the feed roller is driven in a direction to separate from the friction member. In addition, when the feed roller separates from the friction member, the backup member is driven in a direction away from the take-out roller in conjunction with the feed roller.

[Effect]

When paper sheets are jammed between the feed roller and the friction member and cannot be taken out, the feed roller is separated from the friction member, and in conjunction with this, the backup member is separated from the take-out roller.

Further, an opening window 16 is formed in the front part of the receiving box 12, and the pressing surface of a backup plate 18 as a backup member of the backup drive mechanism 17 faces inside the receiving box 12. This makes it possible to press the rear surface side with an appropriate pressure so that the holding state of the banknotes P stored and held in the receiving box 12 is not disturbed. A lever 19 whose base end is attached to the input guide 11 faces inside the receiving box 12, and an excessive input amount detection mechanism 21 is arranged to detect the movement of this lever 19 with a micro switch (not shown). ing. The excessive input amount detection mechanism 21 prevents the loading mechanism 5 from starting loading through its detection operation, and also instructs the customer to reduce the input amount of banknotes P through a display section (not shown). It's becoming like that. In addition, 22
is a first optical detector consisting of a first light source 23 and a first light-receiving element 24, which detects the insertion state of banknotes by detecting the height of the banknotes P inserted from the input slot 3. It's summery.

The backup drive mechanism 17 is constructed as follows. That is, the upper and lower guide frames 2 are attached to the mounting board 25 via the supports 26...
A movable plate 29, which is integral with the backup plate 18, is slidably guided between 7 and 28. First springs 30, 30 are connected to the movable plate 29, and the back-up plate 18 is always urged to protrude into the receiving box 12, and a cam 31 for returning the plate is used to push the back-up plate 18 toward the front of the receiving box 12. It can be moved to a position where it is flush with the wall surface. Note that 32 is a micro switch, which is adapted to detect the operating state of the backup plate 18.

On the other hand, the taking-in mechanism 5 for taking out the banknotes P received by the receiving mechanism 4 configured as described above one by one and sending them to the post-processing mechanism is configured as follows.

That is, a take-out roller 33 is disposed in the banknote pressing direction of the back-up plate 18, that is, at one end of the rear surface of the receiving box 12 so as to be able to protrude and retract into the receiving box 12. The paper is taken out from the take-out port 15 and sent to a multiple-sheet take-in prevention mechanism 36 consisting of a feed roller 34 and a friction member 35. This multiple-sheet taking prevention mechanism 36 separates the banknotes P taken out from the receiving box 12 by the take-out roller 33 one by one while pressing them against the friction member 35 by the feed roller 34 and sends them to the post-processing mechanism. It is designed to be fed into a conveyance path 37. The conveyance path 37 includes a first conveyance belt 39 stretched around a first conveyance roller 38 and a first conveyance belt 3
The pinch roller 4 is biased against the first conveying roller 38 by the second spring 40 via the pinch roller 9 .
It is formed between surfaces facing each other and a second conveyor belt 43 that is stretched around the first and second conveyor rollers 42 .

The friction member 35 is made of a band-shaped rubber member and is provided on the base block 44, as shown in detail in FIG. This base block 44 includes first and second fixing blocks 45, 46 and a locking shaft 47.
is fixedly installed, and the pinch roller 4 is fixedly installed.
1 rotation shaft 48 is pivoted. The friction member 35 is fixed to the first fixing block 45 at one end with its middle part hooked to the locking shaft 47, and fixed to the second fixing block 46 at the other end.
The tension adjuster 49 is attached to the tension adjuster 49, and the tension can be changed by operating an adjustment knob 50 of the tension adjuster 49.

In addition, as shown in Fig. 4, the base block 4
Guide belts 83, 83 are stretched between the pulleys 51, 51 provided on the locking shaft 47 of the pinch roller 41 and the rotating shaft 48 of the pinch roller 41.
The banknotes P are guided to the conveyance path 37 while rotating as the banknotes P rotate. Further, the base block 44 is rotatably supported via a support shaft 82, and the second spring 40 moves the pinch roller 41 in the direction in which it comes into contact with the first conveyance roller 38, that is, the friction member 35 is It is biased in the direction of pressing contact with the roller 34, and thus constitutes a friction member retraction mechanism 52.

As shown in FIG. 5, a cam drive mechanism 53 and a roller drive mechanism 54 are arranged on the lower surface side of the mounting board 25, and are driven by a motor 55 as a common drive source. ing.

First, the cam drive mechanism 53 will be explained.
A timing pulley 56 is fitted on the shaft of the motor 55, and a timing pulley 59 on the input side of the half-rotation clutch 58 is connected via a timing belt 57.
The driving force is transmitted to the When the half-rotation clutch 58 receives a pulse signal, it makes a half-rotation operation and then stops.
It is designed to rotate half a rotation around 0. A take-out roller cam 61, a feed roller cam 62, and the plate return cam 31 are fixed to the output shaft 60, respectively, and these cams 61, 62,
31 rotates half a turn.

The take-out roller cam 61 is connected via a connecting rod 63.
An arm 65, which has a take-out roller 33 attached to its free end and whose proximal end is pivoted to a shaft 64, is connected to a shaft 6.
4, so that a part of the take-out roller 33 is exposed inside the receiving box 12.

Further, the feed roller cam 62 has the feed roller 34 attached to the midway part of the substantially U-shape via a connecting rod 66, and a swing base 67 whose base end side is pivoted to the shaft 64. The feed roller 34 can be retracted in a direction away from the friction member 35 by rotating around the friction member 35. In this way, a retraction mechanism 68 for the feed roller is configured.

Further, as described above, the plate return cam 31 is moved to the receiving box 1 by the first springs 30, 30.
The backup plate 18, which has been urged to protrude into the receiving box 12, is returned to a position flush with the front wall surface of the receiving box 12.

Next, the roller drive mechanism 54 will be explained. A V-pulley 69 is fitted on the shaft of the motor 55, and drives a V-pulley 72 on the input side of the clutch 71 via a V-belt 70. . A gear 74 that is fitted and meshes with the gear 74,
75 to rotate the take-out roller 33 and feed roller 34, which are integrated with gears 74 and 75.

Note that 76 is a second optical detector consisting of a second light source 77 and a second light receiving element 78, and is located in the receiving box 1.
It is designed to detect the presence or absence of banknotes within 2. A third optical detector 79 includes a third light source 80 and a third light receiving element 81, and is adapted to detect the passage of banknotes P from the feed roller 34 to the conveyor 37.

According to such a configuration, when a customer inserts a banknote bundle P into the receiving box 12 and closes the lid 8 at the signal of completion of insertion, a detector (not shown) detects that the lid 8 is closed. At the same time, the first optical detector 22 detects the upright position and the second position of the banknote P.
The optical detector 76 detects banknotes P in the receiving box 12.
The presence of is detected. This detection signal causes the motor 55 to rotate, and at the same time the half-rotation clutch 58
As the output shaft 60 of the clutch 71 rotates half a rotation,
is connected. When the output shaft 60 of the half-rotation clutch 58 makes a half turn, a part of the take-out roller 33 faces into the receiving box 12, the feed roller 34 contacts the friction member 35 with a predetermined pressure, and the back-up plate 1
8 presses the banknotes P against the take-out roller 33 with a predetermined pressure. Also, when the clutch 71 is operated to connect,
The take-out roller 33 and the feed roller 34 rotate. When the take-out roller 33 rotates, the banknotes P are taken out from the receiving box 12 as the take-out roller 33 rotates.
and the friction member 35. Then, when the take-out roller 33 takes out the banknotes P one by one from the receiving box 12, the feed roller 34 leaves the banknotes P as they are when they are taken out one by one from the receiving box 12, and when a plurality of banknotes are taken out at once, the feed roller 34 separates the banknotes one by one and sends them to the conveyance path. Send it to 37. Therefore,
The plurality of banknotes P... are not sent out to the conveyance path 37 in an overlapping manner by this plurality of banknotes taking in prevention mechanism 36. When the banknote P is sent to the conveyance path 37 and its leading edge is detected by the third optical detector 79, the clutch 71 is operated to isolate and the drive of the take-out roller 33 and the feed roller 34 by the motor 55 is released. , banknotes P are conveyor belts 39, 43
transported by. When the rear end of the banknote P is detected by the third optical detector 79, the clutch 7
1 is connected again, and the take-out roller 33 and the feed roller 34 are driven to rotate. In this way, when all the banknotes P in the receiving box 12 are taken out, this is detected by the second optical detector 76, the motor 55 is stopped, and at the same time the output shaft 60 of the half-rotation clutch 58 is further rotated. As the clutch 71 rotates half a turn, the clutch 71 is isolated. Then, the feed roller 34 moves away from the friction member 35, the take-out roller 33 and the backup plate 18 retreat from the receiving box 12, and the feed roller 34 and the take-out roller 33 stop.

In the unlikely event that the multiple-sheet taking-in prevention mechanism 36 is jammed with bent banknotes P, wrinkled banknotes P, etc., and cannot be fed out, the evacuation mechanism 6 for the feed roller
8 and the backup drive mechanism 17, the banknote P
can be easily removed. That is, the output shaft 60 of the half-rotation clutch 58 is rotated half a rotation, and the feed roller 34 is moved from the friction member 35 to the take-out roller 3.
By retracting the backup plates 18 from the banknotes 3 and reducing the contact pressure of the feed roller 34 and the friction member 35 against the banknotes P and the contact pressure of the backup plate 18 and the take-out roller 33 against the banknotes P, the banknotes P can be easily removed. can be extracted. After removing the banknote P,
The half-turn clutch 58 is further turned half a turn to bring the feed roller 34 into contact with the friction member 35.

[Effect of idea]

As explained above, according to the present invention, paper sheets are also taken out from the storage section that accommodates a plurality of sheets at once as the take-out roller rotates, and the paper sheets are connected to the feed roller and the friction member for preventing multiple sheet taking. A retraction mechanism for the feed roller that drives the feed roller in a direction toward and away from a friction member in a paper sheet take-out device that feeds paper sheets between the two and separates and takes out the sheets one by one as the feed roller rotates. a back-up member that presses paper sheets in the storage section against the take-out roller with a predetermined pressure; and a retraction mechanism for the feed roller that drives the back-up member in a direction away from the take-out roller when the feed roller separates from the friction member. Although it has a relatively simple structure because it is equipped with a back-up drive mechanism, in the unlikely event that paper sheets become jammed between the feed roller and the friction member and cannot be taken out, the feed roller At the same time, the back-up member can also be retracted in conjunction with the retraction of the back-up member, thereby producing excellent effects such as being able to easily take out the paper sheets.
