Abstract

PURPOSE:To improve reliability on drawing out action by arranging sending rollers on both sides in width direction of paper leaves, separately adjusting pressing forces of both rollers independently with an adjusting means, detecting sending speeds of both sides of the paper leaves, and controlling the adjusting means with the data. CONSTITUTION:When paper moneys 13 are drawn out, initial drawing out rollers R1, R2 both right and left sides in width direction of paper moneys 13 are driven in rotation, and one sheet of money is drawn out from the uppermost of the paper moneys 13 in a housing box 12. At this time, an initial drawing out condition is detected by right and left detecting rollers S1, S2, right and left sensors S3, S4, and a timing detecting sensor S6, and a present skew degree of the paper money and a degree of drawing timing are detected herewith. Most suitable pressing forces for right and left pressing force adjusting mechanisms 15, 16 are separately adjusted independently. Therefore, the paper moneys 13 are always corrected in a normal drawing out condition, balance between an initial sending force and separation restraining force by a feed roller R3 and a gate roller R5 is maintained, so that the paper moneys can be sent out in stable condition.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field of application The present invention relates to a paper sheet dispensing device that is internally configured in an automatic teller machine that handles paper sheets such as banknotes, and more specifically, The present invention relates to a paper sheet feeding device capable of feeding out leaves while adjusting the initial feeding state of the sheets.

(B) Prior art In general, this type of paper sheet feeding device, as shown in FIG. 7 and FIG. paper sheets 7
The paper sheets 73 are fed out one by one by an overlap type feed roller 74 and a gate roller 75, which control the feeding of the fed paper sheets 73 one by one.

In this case, the feeding gap in the overlap part is always set to an optimal value to ensure stable feeding without any feeding defects. However, for example, when handling circulating banknotes,
If the product is bent, bent, weak, or has foreign matter such as tape or glue attached, the gate roller's restraining force may not be able to follow it sufficiently, resulting in skew or slight fluctuations in the feeding pitch at the initial stage of feeding. In addition, due to various fluctuations in the feeding conditions, the balance between the initial feeding force of the feed roller inside the bill storage section and the separation restraining force of the feed roller and gate roller outside the bill storage section is disrupted. Moreover, it is easy to cause feeding defects such as skew, jam, continuous feeding, and blank feeding, and has the problem that perfect feeding cannot be expected.

(C) Problems to be Solved by the Invention This invention provides a method for feeding out paper sheets in which the feeding posture of the paper sheets is adjusted to a perfect feeding posture at the initial feeding stage of the paper sheets, and then the paper sheets are fed out. The purpose is to provide equipment.

A paper sheet feeding device comprising a separation unit that controls feeding of the fed paper sheets one by one using a feed roller and a gate roller, the feeding rollers being arranged at positions on both sides of the paper sheet width direction. and a pressing force adjusting means for individually and independently adjusting the pressing force of both rollers, and a pressing force adjusting means located at both sides in the width direction of the paper sheet,
a feed speed detection means for detecting the feed speed of both sides of the paper sheets that are sent out in contact with the stored paper sheets; and a control means that controls the pressing force adjustment means based on the detection data of the feed speed detection means. This is a paper sheet feeding device equipped with the following.

(E) Effect of the Invention According to this invention, when paper sheets are fed out one by one from the storage section, in the initial feeding stage, the feeding speed detection means is fed out to determine the speed of the filtered paper sheets, and from this speed. The current feeding timing degree, gap level, etc. of paper sheets are detected, and based on this detection data, the control means controls the feed rollers on both sides via the pressing force adjustment means according to the speed of each sheet. The optimal pressing force for proper feeding such as pressurization and depressurization is individually adjusted.

(f) Effect of the invention As a result, the pressing force adjusting means outputs the optimum correction value corresponding to the current initial feeding detection data for each sheet, and adjusts the initial feeding force of the feed roller inside the storage section and the storage section. To always maintain a normal balance between the separation restraining force of an outer feed roller and a gate roller.

Therefore, even if various feeding conditions fluctuate and paper sheets tend to be fed out unstably, the initial feeding position of the feed roller absorbs and eliminates the skew and fluctuations in the feeding pitch, and corrects the paper to the perfect feeding position. To perform a reliable feeding operation that can be fed out.

The banknote 13 described above is pressed and urged to be received here, and the received banknote 13 on the uppermost surface can be fed out by these rollers R1 and R2. Waiting status.

When driving these left and right initial feed rollers R1, R2, the rotation transmission force from the initial feed motor M2 with a built-in clutch is transferred via the horizontal shaft 18 installed in the feed width direction and both transmission belts Bl, B2. Both rollers R1, R
By transmitting the drive to the banknote 2 and rotationally driving both rollers R1 and R2, the banknotes 1 on the top surface are sequentially removed from the banknote storage box 12.
3 is initially fed out.

Further, for these left and right initial feeding rollers R1 and R2, the pressing force adjustment mechanisms 15.16 are provided so that the pressing contact force of both the rollers R1 and R2 can be individually and independently adjusted. .

The above-mentioned pressing force adjustment mechanism 1.5.16 includes left and right pressing motors M3. The rotation transmission force from M4 is transferred to the left and right pressing force transmission bells)B3. The rotational force is transmitted to the left and right pressing arms 19.20 which are pivotally supported on the horizontal shaft 18'2 through B4, and the suppression arms 19.20 that receive this rotational force use the horizontal shaft 18 as a rotation fulcrum.
The left and right initial feed rollers R1 and R2 pivotally mounted at the tips of the arms 9 and 20 can be individually and independently adjusted downward.

Further, a left detection roller S1 is independently disposed near the left initial feed roller R1, and a right detection roller S2 is independently provided near the right initial feed roller R2, and these detection rollers Sl and S2 are as described above. Similar to the initial feeding rollers R1 and R2, they rotate with the feeding operation of the banknotes while facing the upper surface of the stacked banknotes 13, and during this initial feeding, the rotation speeds of the left and right detection rollers Sl, 82 are compared. It is designed to detect the gap level of the initially fed banknote ↑3.

At the feeding position of the feeding path 14, there are left and right feed rollers R3 and R4 equipped with high friction members 21 such as rubber materials on a part of the circumferential surface for feeding one sheet in one rotation, and left and right feed rollers R3 and R4 in the feeding direction. Left and right gate rollers R5 and R6 for single sheet output control which regulate the rotation of the feed rollers R5 and R6 are arranged in a so-called overlap type with unevenness to promote separation, and one feed roller R3 is equipped with a timing detection sensor S6. is arranged to detect one rotation of the feed roller and control the timing for feeding out each bill 3, so that the bills are fed out at a fixed pitch.

Further, at the downstream position of these rollers R3 to R6, left and right feed-out detection sensors S3. By arranging S4,
As shown in FIG. 4, the timing and skew state of the bills 13 being dispensed are detected.

At the initial feeding stage when the banknotes 13 are fed out from the banknote storage box 12, the degree of gap is detected by the left and right detection rollers 81°S2, and in addition to this, the degree of gap is detected by the left and right feedout detection sensors 83 and 84. is detected, and based on these detection data, the pressing forces of the left and right initial feeding rollers R1, R2 are independently adjusted individually to control feeding while adjusting to the optimum feeding state. As a result, the banknotes 13 to be fed out are corrected to an appropriate feeding state in which deviations in the timing of feeding and the degree of gap are eliminated, and the banknotes 13 are fed out.

FIG. 5 shows a control circuit block diagram of the banknote feeding device,
The CPU 51 detects both the left and right detection rollers Sl.

The output degree of each motor M1-M4 is controlled according to the detection data detected and inputted from S2 and each detection sensor S3-S6 and the program stored in ROM 52, and the necessary control data is stored in R, A M2S.

The processing operation of the bill dispensing device configured as described above will be explained with reference to the flowchart of FIG. 6.

= 9- Now, when feeding out the banknotes 13 one by one, first, the initial feeding motor M2 is operated to drive the left and right initial feeding rollers R.
1 and R2 are rotationally driven (first step nl).

As a result, the banknote j3 waiting on the top surface of the banknote storage box 12 receives the feeding rotational force, and one sheet is taken out from the banknote storage box 12 (second step n2).

At this time, the initial feeding state of the banknotes 13 to be fed is determined by the left and right detection rollers Sl, S2, and the left and right feeding detection sensors S.
3. S4 and the timing detection sensor S6, thereby detecting the degree of gap, the timing of feeding, etc. of the current banknote (third to fourth steps n).
3-n4).

Based on this detection data, the CPU 71 or the left and right pressing force adjustment mechanisms 15.16 independently adjust the optimal pressing force such as pressurization and depressurization. For example, if the - side is a little behind the standard feeding timing and tends to cause skew, the pressing force on that side is increased in accordance with the amount of detected data, and the feeding force on that side is accelerated. On the other hand, if the detected data precedes the standard feeding timing, the pressing force on that side is reduced according to the amount of detected data,
Slow down the feeding force on that side (5th to 6th steps n5~
n, 6).

In this way, the banknote 13 that has been suppressed and adjusted is always corrected and fed out to a normal feeding state, and each time a banknote 13 is fed out, the pressing force adjustment mechanism], 5.16 is returned to the initial state, When such a feeding operation is repeated and a predetermined number of sheets have been fed out, feeding ends (seventh to ninth steps n7 to n9).

As mentioned above, the pressing force adjustment mechanism outputs the optimal correction value corresponding to the current initial feeding detection data for each sheet, and the initial feeding force of the initial feeding roller and separation prevention by the feed roller and gate roller are controlled. In order to always maintain a normal balance with the force, even if the various feeding conditions fluctuate and the banknotes are unstably fed out, the initial feeding position absorbs and eliminates the fluctuations such as skew and feed piston, allowing the banknotes to be completely dispensed. To perform a highly reliable feeding operation that can be corrected to a proper feeding posture and fed out.
