Abstract

PURPOSE:To separate and carry bank notes at constant intervals and in a good condition almost free from a posture change by applying coincidence to both of leading ends of friction members in pickup and feed rollers. CONSTITUTION:Bank notes (a) are dislocated lower than a group of of other notes for being fed to the neighborhood of a separation point 'R' comprising a feed roller 12a and a gate roller 14a via the carriage force of a high friction member 46b, with the turn of a pickup roller 13a. Then, when only one of the bank notes (a) is passing the separation point 'R', the leading end thereof is at the position Q1 and the trailing end at the position P1. When the note (a) has further advanced, the trailing end thereof comes to the position P2 and the leading end to the position Q2, thereby being completely free from the carriage force of the high friction member 46 of the pickup roller 13a. When the trailing end of the note (a) is moving from the positions P1 to P2, however, the next note (b) is given a carriage force from the trailing end part of said high friction member 46a and moves lower than a group of other notes, finally reaching the neighborhood of the separation point 'R'.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet separating device that separates and conveys banknotes stored in a hopper one by one, such as in an automatic teller machine. It is something.

[Conventional technology]

In conventional devices, for example, as described in Japanese Unexamined Patent Publication No. 56-65733, the friction member of the pickup roller is brought into contact with the banknote earlier than the friction member of the feed roller to feed the banknote in order to align the leading edge of the banknote. Ta.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, since the friction member of the pickup roller feeds the banknote in advance to the engagement point between the feed roller and the gate roller, the banknote may be fed out by a portion of the feed roller other than the friction member 7a. Also,
In the case of crooked banknotes, only one pickup roller may come into contact with the banknote, which may result in poor posture of the banknote.

711. As described above, in the above-mentioned conventional technology, when the banknotes are thrown into the hopper in a skewed, unevenly folded state, it may not be possible to stably separate and transport the banknotes one by one from a group of banknotes.

An object of the present invention is to provide a paper sheet separation device that can solve the above-mentioned problems.

[Means for solving problems]

The above purpose is to provide a pickup roller with a friction member on a part of the roller that feeds out a group of banknotes that are thrown in at once, and a friction member on a part of the roller that separates the banknotes fed by the pickup roller one by one. A separation point is established by a feed roller that rotates in the conveyance direction, and a gate roller that is offset in the axial direction, faces the feed roller, is arranged so as to overlap the feed roller, and that does not rotate in the conveyance direction and is provided with a friction member around the entire circumference. The front end of the friction member of the pickup roller is aligned with the front end of the friction member of the feed roller, and the length of the friction member of the pickup roller is adjusted so that the length of the friction member of the pickup roller is set so that the front end of the friction member of the pickup roller matches the front end of the friction member of the feed roller. This is achieved by applying a conveying force to the conveyor.

[Operation] The bills that have been thrown in irregularly are sufficiently conveyed to the vicinity of the separation point by the conveyance force of the pickup roller, so that they are separated and conveyed at regular intervals and in a good condition with little change in posture.

receives a pressing force from the spring 38 to press the bill against the pickup roller 13a.

Next, an example of the operation of this embodiment will be explained using FIGS. 3, 5, 6, and 7. First, in FIG. 3, when trying to separate the banknotes in sequence starting from the top A of the banknotes being thrown in,
The bill is pressed against the pickup roller 1.3a by the spring 38 and the push plate 16, and the pickup roller 13
Due to the rotation of a and the conveying force of the high friction member 46a,
Bill A has a feed roller 12a and a gate roller 1.4.
In order to be fed into the vicinity of the separation point R formed by a, the banknotes are shifted downward from other banknote groups. Next, when only one banknote A is about to pass through the separation position R as shown in FIG. It is transported by the force to the position Ql, while the rear end side is at the position Pl where the transporting force from the high friction member 46a of the pick-up roller 3a is lost. As the bill advances further, as shown in FIG.
This results in a situation where the conveying force of a is not applied. However, while the rear end of the banknote A moves from the position Pl to the position P2, the next banknote opening of the banknote A is given a conveying force from the rear end of the high friction member 46a of the pickup roller 13a. It moves downward from other banknote groups and reaches the vicinity of separation point R. Since the bill slot is sent to the separation point R by the conveying force of the high friction member 46a of the pickup roller i 3 a, there is a concern that the bill may be sent out overlapping with the bill A, but the difference between the bill A and the bill slot at the separation point R is The resistance force exerted by the gate roller 14a to stop the banknote opening is greater than the conveying force that causes the banknotes to overlap (the coefficient of friction of the gate roller 14a is greater than the coefficient of friction of the banknote), so one sheet is reliably delivered. Can be separated. ”
The operations described in item 1 are performed sequentially.

Further, in FIG. 7, the required length LF of the high friction member 45a of the feed roller 12a is set larger than the distance Q1 from the 1-separation position R to the gate roller guide 39, and the high friction member 4.6a of the pickup roller 13a is The required length Lp
This indicates that it is desirable to set the value to be larger than the value obtained by subtracting the distance Q2 from the gate roller guide 39 to the center of the pickup roller 13a from the banknote width.

According to the present invention, it is possible to constantly feed the front ends of banknotes that have been thrown in irregularly into the vicinity of the separation position 1iR during the separation operation, and the banknote face distance is constant and the banknotes can be separated and transported with little change in posture. It becomes possible.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to adjust the postures of banknotes to be separated and conveyed by the correction effect of the conveyance force of the pickup roller.
