Abstract

PURPOSE:To prevent such trouble as jam by furnishing a rotation control part to provide rotation of a payoff roller in a certain amount in payoff direction, and thereby paying off sheets with eventual folding at corners without risk of skewing. CONSTITUTION:When set between a payoff roller 5 and a pressure member 3, sheets are primary pressed by said pressure member 3, and when sheets are pressed, a rotation control part 11 will start to rotate the payoff roller 5 for a certain amount. Even though the foremost sheet has folding at any corner, the bottom of the sheets is dropped forcedly in a payoff groove with the whole surface of the bottom. If the pressure member 3 retracts and paying- off is made by secondary pressure, the sheets are paid off without skew to ensure that even sheets with eventual folding at corners are paid off smoothly.

Description

[Detailed Description of the Invention] [Summary] This is a control method when a banknote inserted into a banknote slot of an automatic teller machine or the like is pressed and pressed once by a press plate, then retreated, and then pressed again to start feeding. When first pressed with the pressure plate, the feed roller slightly moves.

By rotating in the feeding direction, it is possible to prevent banknotes having folds at the corners from skewing during feeding.

C. Industrial Application Field] The present invention relates to a cash handling device used in financial institutions, etc., and in particular can prevent skewing when feeding out banknotes with folds at the corners. It relates to a feeding device. .

Recently, as part of the computer banking system, automatic cash/deposit payment machines (
＾automatic Teller Machine
:Hereinafter referred to as A.

Automated transaction devices that handle cash, such as TM), are widely used.

It is desired that these devices be able to feed out banknotes inserted into the banknote slot without skew even if the corners of the banknotes are bent.

[Conventional technology]

FIG. 5 is a side view illustrating the main parts of the bill dispensing device.

In the figure, l is a banknote, 2 is a banknote slot, 3a is a pressure plate, 4 is a pink roller, 5a is a feed roller, 6 is a separation roller, 7 is a holding plate, 8.9 is a feed roller,
S represents a sensor, Ml represents a pulse motor, and M2 represents a motor. Pick roller 4. and feed roller 5a are connected to pulse motor L, and feed rollers 8 and 9 are connected to motor M2.
is connected to.

In the figure, a gap g is provided between the right end of the holding plate 7 and the feed roller 5a, through which the banknote 1 is fed out. Further, the separate roller 6 faces the feed roller 5a with a slight gap therebetween, has a one-way clutch 6a built therein, and does not rotate in the direction in which the banknotes 1 are fed out. Each roller is molded from a resin material 9, such as rubber.

With such a configuration, when banknotes 1 are inserted into the banknote slot 2 for deposits, etc., the pressure plate 3a and the pick roller 4. When the press plate 3a is inserted between the feed rollers 5a and the holding plate 7 and a press button (not shown) is pressed, the sensor S detects this and the press plate 3a is moved in the direction of the arrow A under the control of a control unit (not shown). Moving forward, at point a shown in the timing chart of FIG. 6, the pressing plate 3a pushes the banknote 1 onto the pick roller 4. And after the primary pressure is applied to the feed roller 5a, at the point where the arrow B
retreat in the direction.

Then pick roller 4. The banknote 1 once pressed against the feed roller 5a is released from the pressure, and the lower end of the frontmost banknote 1 falls into the gap a between the feed roller 5a and the holding plate 7.

Next, the pressing plate 7 moves forward again and pushes the banknote 1 onto the pink roller 4 at point C in FIG. When the banknote 1 is secondly pressed against the feed roller 5a and the motor M2 is driven, and then the pulse motor gate is intermittently driven from point d in FIG. The friction of 6 prevents double feeding and feeds out one sheet at a time. The sent banknote 1 is conveyed by a feed roller 7.8.

The transported banknotes 1 are checked for authenticity, denomination, etc. in a checking section, counted, and displayed on a display. When the customer presses the confirmation button, the item is stored in the storage safe.

The identification section, display, confirmation button, and storage safe are all not shown.

[Problem that the invention seeks to solve]

According to the above-mentioned conventional method, if the frontmost banknote 1 inserted into the banknote input slot 2 has a crease at one corner as shown in FIG. When the banknote 1 moves backward, only the unbent side of the banknote 1 is drawn into the gap g between the feed roller 5a and the holding plate 7 at the lower end of the banknote 1, making the banknote 1 oblique. Therefore, if the paper is fed out as it is, it will run diagonally, causing problems such as paper jams, and the operation of the apparatus will be stopped. If the first banknote 1 is fed out without being skewed, the banknote 1 will be fed out relatively smoothly even if subsequent banknotes 1 are folded, so it is important to prevent the first banknote 1 from being skewed.

Measures to solve problem C] FIG. 1 is a block diagram of the principle of the present invention.

In the figure, 5 is a feed-out roller whose rotation is controlled intermittently; 3 is a pressing member that is arranged opposite to the feed-out roller 5 and moves forward/backwards; and 11 is a pressure member that moves the feed-out roller in the feeding direction when the pressing member primarily presses the sheet. This is a rotation control unit that rotates the rotation by a predetermined amount. The predetermined amount is the amount of rotation that allows the lower end of the paper sheet to fall into the feeding groove below the front surface of the feeding roller 5.

Therefore, during the primary pressing by the pressing member 3, the feeding roller is rotated by a predetermined amount in the feeding direction under the control of the rotation control section 11, and then the pressing member 3 is moved back.

[Effect]

When a sheet of paper is inserted between the feeding roller 5 and the pressing member 3, it is first pressed by the pressing member 3, and when the sheet is pressed, the rotation control unit 11 is activated to move the feeding roller 5 by a predetermined amount. Rotate. Then, even if the corner of the frontmost sheet is folded, the lower end of the sheet is forced to fall into the feeding groove over the entire surface. Therefore, when the pressing member 3 is moved back and feeding is performed by secondary pressing, the paper sheets are fed out without skew, so that even if paper sheets with folds at the corners are inserted, the sheets can be fed out smoothly. can.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. 2 is a block diagram showing an embodiment according to the present invention, FIG. 3 is a process diagram explaining the operation of FIG. 2, and FIG. 4 is a timing chart of FIG. 2. The same reference numerals indicate the same objects throughout the figures.

In FIG. 2, parts corresponding to those in FIG. 1 are shown surrounded by a chain line. In addition, the main control section 10 has many of the functions of the control section explained in the conventional example.
It also has a function of starting the primary pressing rotation control section 11a when the primary pressing by the pressing plate 3a is performed.

The primary pressing concave rotation control section 11a has a function of controlling the rotation of the delivery roller 5 by a predetermined amount based on a command from the main control section 1o, and also notifying the main control section 1o of the end of rotation. Also 12
1 is a sensor amplifier, 13 and 14 are motor drivers, and M3 is a motor.

Since it has such a configuration and function, the operation will be explained with reference to the process diagram in FIG. 3 and the timing chart in FIG. 4. First, as shown in FIG. When inserted, the banknote 1 is detected by the sensor S.

Next, as shown in FIG. 3(b), a command is issued from the main control unit 10, the motor M3 is driven, and the pressing plate 3a moves forward in the direction of arrow A. At point a in FIG. Pino crawler 4. by pressing plate 3a. and is primarily pressed by the feed roller 5a. Here, a command is issued from the main control section 1o to start the primary pressure rotation control section 11a, and the pick roller 4. is moved from point e to point f in FIG. 4 by driving the pulse motor M1. and feed roller 5a by a predetermined amount.

For example, it is rotated by 70 m5. Then, the banknote 1 is slightly fed out, and the lower end of the banknote 1 falls over the entire surface into the gap g between the holding plate 9 and the feed roller 5a.

Next, as shown in FIG. 3(C), the pressing plate 3a moves in the direction of arrow B by the reverse rotation of the pulse motor h at the point in FIG.
Then, as shown in FIG. 3(d), the pressing plate 3a is driven forward again by the motor 6, and the bill 1 is moved back to the pick roller 4. at point C in FIG. When the feed roller 5a is secondarily pressed, the motor h is driven, and the pulse motor h is intermittently driven, the banknote 1 that has already fallen into the gap g
is the pick roller 4. The feed roller 5a feeds out without skew, and is conveyed by the feed rollers 7 and 8, followed by the pick roller 4. Subsequent banknotes 1 are also smoothly fed out one by one by the intermittent rotation of the feed roller 5a.

In this way, by rotating the pink roller 4° and the feed roller 5a by a predetermined amount during the primary pressing, the entire lower end of the frontmost banknote l can be placed into the gap g between the holding plate 9 and the feed roller 5a. Even if the corner of the paper is bent, it can be fed out without skewing, reducing jamming of banknotes caused by skewing, and preventing the device from stopping.

Although the above example describes a case where banknotes are handled, the present invention can be generally applied to paper sheet feeding devices.
