Abstract

PURPOSE:To perform stabilized supplying of paper sheets by detecting the conditions in which the paper sheets are being supplied, and controlling the pressing force of a roller by an optimum amount of operation by means of a fuzzy inference control means based on fuzzy rules. CONSTITUTION:When bills 13 are supplied from a stacker 12 one at a time by driving a pair of the right and left pressing motors M3, M4, the bill supplying conditions such as the degree of skew, the degree of supply timing, the degree of feed pitch, the degree of bill length, etc., are detected through detecting sensors S1-S4. Based on the respective detected elements, the amounts of operations of the respective pressing motors M3, M4 of the right and left pressing force adjusting mechanisms 15, 16 are fuzzy inference-controlled so that a fuzzy controller may have an optimum pressing force on the basis of a fuzzy rule table. Thus, the pressing motors M3, M4 of the pressing force adjusting mechanisms 15, 16 output the most adequate amount of pressing operation in response to the detected elements, and thus, even when the tendency of defective bill supplying operation occurs, the fuzzy control device can respond to the tendency and constantly cope with the defective bill supply operations by proper supplying pressing force so as to supply the bills stably.

When driving, the rotation transmission force from the initial feed motor M2 with a built-in clutch is transmitted to the rollers R1 and R2 via the horizontal shaft 18 installed in the width direction of the feed and both transmission belts B1 and B2. By rotationally driving both rollers R1 and R2, the banknotes 13 on the upper surface are sequentially fed out from the stacker 12 in an initial stage. Furthermore, the left and right initial feeding rollers R1 and R2 are provided with pressure force adjustment mechanisms 15 and 16 on the left and right so that the pressure contact force of both the rollers R1 and R2 can be adjusted independently. . The above-mentioned pressing force adjustment mechanisms 15 and 16 transfer the rotational transmission force from the left and right pressing motors M3 and M4 to the left and right pressing force transmission belts B3 and B4.
Left and right pressing arms 19 are pivotally supported on the horizontal shaft 18 via
, 20, and the pressing arm 1 receives this rotational transmission force.
9 and 20 are the arms 19 and 2 with the horizontal shaft 18 as a pivot point.
Each of the left and right initial feeding rollers R1 is pivotally connected to the tip of 0.

} If it is detected that the banknote is not skewed (Z) during the initial feeding and is fed out with only the feeding timing being greatly delayed (PL), the initial feeding roller R for the banknote
Since the pressing force of R1, R2 is insufficient, both the left and right rollers R1,
The pressing force of R2 is increased (PL) (PL) to forcefully contact the banknotes 13 to be fed out to apply a strong feeding force, and the output is set so that appropriate feeding timing is achieved. if Skew degree = Z Feeding timing degree = PL then M3 = PL M4
=PL {Rule 2} If it is detected that the banknote does not skew during initial feeding (Z), the feeding timing is quite early (NL), and the feeding pitch is appropriate (Z). At that time, the pressing force of the initial feeding rollers R1 and R2 is weakened on both the left and right sides (PS) (P
S): A relatively gentle and weak feeding force is applied to the banknotes to be fed out by applying low-pressure contact, and the output is set to achieve an appropriate feeding timing. if Skew degree = Z Feed timing degree = NL Feed pitch degree = Z then M3 = PS M
4 =PS {Rule 3} If it is detected that the banknotes are not skewed (Z) and the banknotes are fed out at an appropriate timing (Z) during initial feeding, the banknotes are fed out stably. At that time, in order to maintain the current feeding conditions, the pressing force of the left and right initial feeding rollers R1 and R2 is kept constant (PM) (PM), and a constant and stable feeding force is applied to the banknotes being fed. give. if Skew degree = Z Feeding timing degree = Z then M3 = PM M4
=PM {Rule 4} If during initial feeding, if it is detected that the banknote is skewed to the right with a considerable lead to the right (PL), then the pressing force of the left initial feeding roller R1 is increased (PL), and the right initial feeding is performed. The skew is corrected by weakening the pressing force of the roller R2 (PS) and applying an appropriate feeding difference to the left and right sides in the width direction of the banknote to be fed. if skew degree = PL then M3 = PL M
4 = PS {Rule 5} If it is detected that the banknote is skewed to the left in the initial feeding stage (NL), then the pressing force of the left initial feeding roller R1 is weakened (PS), and the pressing force of the left initial feeding roller R1 is weakened (PS). The pressing force of the feeding roller R2 is increased (PL) to correct the skew by applying a feeding difference to the left and right sides of the banknote to achieve an appropriate feeding state. if skew degree=NL then M3=PS M
4 = PL {Rule 6} If it is detected that the length of the banknote is quite long (PL) at the time of initial feeding, the left and right initial feeding rollers R1,
Both the pressing forces of R2 are weakened (PS) (PS), and a relatively gentle and weak feeding force is applied to the banknotes being fed out by applying low-pressure contact to the banknotes, thereby promoting separation of the banknotes and reliably feeding them one by one. Set it as follows. if banknote length = PLthen M
3 =PS M4 =PS {Rule 7} If it is detected that the feeding pitch of the banknote is a fairly long pitch (PL) at the time of initial feeding, since there is a tendency to empty the banknote at that time, the initial feeding of the left and right banknotes is Roller R1
, R2 are both strengthened (PL) (PL) so as to make strong contact with the bills to be dispensed and to ensure that they are dispensed one by one. if feed pitch degree = PLthen

As mentioned above, since the left and right pressing motors of the pressing force adjustment mechanism output the most appropriate amount of pressing operation corresponding to the detection element, there is no tendency for sudden or gradual feeding failures to occur. Even when the occurrence of multiple feeding failure trends is detected, it is possible to always respond to these trends with an appropriate feeding pressure force, and to maintain highly reliable and stable feeding control operation. can be executed.
