Abstract

PURPOSE:To stabilize the conveying cycle of a bill by checking conveying force in a low friction factor member of a pickup roller through a guide, and performing the delivery of the bill with only a high friction factor member of the pickup roller. CONSTITUTION:When a high friction factor member 46 of a pickup roller 13a comes into contact with a bill at time of delivering this bill, a guide 60 is not related to the contact state, whereby the bill is fed into a separating point at the downstream so properly. However, when a paper friction member of the roller 13a is rotated to a position where it contacts with the bill, conveying force to the bill is not produced in the paper friction factor member because the guide 60 comes into contact with the bill. With this constitution, the bill in a bill group comes to be delivered piece by piece at timing by only the high friction factor member of the roller 13a so that the bill is fed into the separating point at a stable cycle all the time.

Description

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

[Conventional technology]

In a conventional device, for example, as described in Japanese Patent Application Laid-Open No. 56-65733, paper sheets stored in a hopper are sent downstream by a friction member provided on a pickup roller, and then sent to the next The sheet of paper came into contact with a roller surface other than the friction member of the pickup roller and was sent downstream.

[Problem to be solved by the invention]

In the above-mentioned prior art, the conveying force of the outer circumferential surface of the pickup roller other than the rubber portion is significantly smaller than the resistance force of the separation resistor that separates banknotes one by one. Otherwise, the 5 banknotes are not taken into consideration so that they do not disappear, and the 5 banknotes are sent out by the conveying force of the outer circumferential surface of the roller other than the rubber part of the pickup roller (e.g., aluminum surface, stainless steel surface, plastic surface). The cycle with the banknotes that will be sold will be significantly shortened,
There was a problem with duplicate sending.

An object of the present invention is to provide a paper sheet handling device that solves the above-mentioned problems and enables a constant feeding cycle.

[Means to solve the problem]

In order to achieve the above object, - a plurality of high friction coefficient members (for example, rubber) are provided in the axial direction of a part of the roller that feeds out the group of banknotes to be thrown in, avoiding the folding position of the banknote; a pickup roller; a feed roller that rotates in the conveying direction and is provided with a high friction coefficient member (for example, rubber) as a part of the roller for separating the bills fed by the pickup roller into individual bills; A separation point is provided by a gate roller, which is arranged so as to overlap the feed roller and oppose to the feed roller, and which does not rotate in the conveying direction and has a high friction coefficient member on the entire circumference. When a banknote comes into contact with the high friction coefficient member of the pickup roller on both sides of each roller, the banknote does not come into contact with the banknote, and in the case of a roller surface other than the high friction coefficient member of the pickup roller, 1
A pickup roller guide with a thin width and dimensioned so as to come into contact with banknotes is provided.

[Effect]

A plurality of pickup rollers are arranged in the axial direction, and a part of each roller has a high friction coefficient member and the other part has a low friction coefficient member. When feeding out banknotes, the high friction coefficient member of the pickup roller When making contact with a banknote, the pickup roller guide does not take part in the contact state, so the banknote is reliably sent to the downstream separation point, but the low JI of the pickup roller! When the friction member rotates to a position where it comes into contact with the banknote, the pickup roller guide comes into contact with the banknote, so no conveying force is generated on the low friction coefficient member of the pickup roller to convey the banknote. The banknotes are fed out one by one at the timing of only the high friction coefficient member portion of the pickup roller, and the banknotes are always fed to the downstream separation point at a stable cycle, resulting in a good banknote conveyance state.

(The configuration of the rollers is the same for all three, and here the deposit port is taken as a representative example.) The feed roller shaft 50 includes a feed roller 12a having a high friction coefficient member 45a on a part of the roller circumference. Gate roller 14 which is attached to
The feed rollers 48 are disposed so as to be axially offset from each other and overlap with each other, and only the outer feed roller 48 has a high friction coefficient member on the entire circumference thereof. Further, a guide roller 47 is provided on the outside thereof, and a timing pulley 43 is provided to transmit rotation to the timing pulley 43 of the pickup roller shaft 49 via the timing belt 44. On the pickup roller shaft 49, a pickup roller 13a made of a low friction coefficient member (for example, aluminum or plastic) is provided to avoid the creases of the banknotes, and a high friction coefficient member 46 is provided on this roller.
In a, the high friction coefficient member and the front end portion of the feed roller are provided in the same phase in the conveyance direction. Furthermore, on both sides of each of the pickup rollers 13a, pickup roller guides 60 are disposed on the front plate 37, as shown in FIG. The pickup roller guide 6° protrudes from the high friction coefficient member 46a of the pickup roller 13a as shown in FIG.

As shown in FIGS. 7, 8, and 9, the pickup roller guide 60 similarly interferes with the folds of one banknote because the pickup roller 13a is located at a position that avoids the folds of the banknote. The pinch roller 42 does not
The entire circumference of the feed roller is located at a position facing the high friction member 48, and is brought into pressure contact with the feed roller 48 by the tensile force of the spring at the other end of the support member 41. Front plate 37° Gate roller guide 3
9 serves as a banknote guide, and the pushing plate 16 receives the pushing force from the spring 38.

It is pressed against the bill pickup roller 13a.

Next, FIG. 3 shows an example of the separation operation in this embodiment.

This will be explained using FIGS. 10 and 11. In FIG. 3, when trying to separate the first banknote A of the group of banknotes in sequence, one banknote is pressed against the pickup roller 13a by the spring 38 and the push plate 16, and as the pickup roller 13a rotates, the pickup roller 13a
By the conveying force of the high friction coefficient member 46a, the banknote I is sent to a separation point formed by the feed roller 12a and the gate roller 14a, and is further conveyed downstream as shown in FIG. During this operation, the bill slot comes into contact with the pickup roller guide 60 provided on the front plate 37 and stops, and the one bill slot does not come into contact with the low friction coefficient member 13a of the pickup roller. The conveyance force generated by the rotation of the high friction coefficient part @46a causes the banknote to be fed to the separation point in the same way as banknote A, and the banknote transport cycle is maintained at a substantially stable distance #IL as shown in FIG. FIG. 12 shows another example of the present invention, and shows an example of an eccentric pickup roller in which the rotation center of the pickup roller 13a is shifted. In this embodiment as well, after one banknote is sent out by the high friction coefficient member 46a of the pickup roller, the pickup roller guide 60 can prevent the low friction coefficient member 13a of the pickup roller from coming into contact with the banknote opening. A longer conveyance period can be obtained.

(Effects of the Invention) According to the present invention, the conveying force of the low friction coefficient member 13a of the pickup roller is blocked by the pickup roller guide 60, and one banknote is fed out only by the high friction coefficient member 46a of the pickup roller. The transport cycle becomes stable, the rejection rate is reduced, and the occurrence of failures is reduced, making it possible to realize a highly reliable device.
