Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a payout control device for a bill depositing and dispensing machine that can prevent jams in the lower opening of a stacker.

"Prior Art" Conventionally, there has been known a bill dispensing device that dispenses bills one by one from a cassette in a bill processing machine such as a bill counting machine or a bill dispensing machine. As an example of this type of banknote dispensing device, as seen in Japanese Patent Application Laid-Open No. 111246/1983, it performs a normal dispensing operation and, when the dispensing operation is completed,
A device that reverses the kick-out roller and feed-out roller, etc. to return the banknotes protruding from the stacker into the feed-out mechanism into the stacker, thereby preventing banknotes from remaining in the feed-out mechanism when the stacker is pulled out. Are known.

In addition, as another example, as seen in Japanese Patent Application Laid-open No. 1-303267, banknotes sent as deposited banknotes are
When the banknotes are sent out as withdrawal banknotes, the direction of movement is changed and the banknotes are sent out with either the rear end of the deposited banknotes or the front end of the withdrawal banknotes, which causes the front end of the deposited banknotes to be bent. Even if the bill is dispensed as a dispensing bill, it will be dispensed from the rear end side, so the bending of the front edge will not affect the dispensing of the bill, and the bill will be There are known devices that allow for smooth feeding.

``Problems to be Solved by the Invention'' By the way, the device disclosed in Japanese Patent Application Laid-Open No. 111246/1983, when the banknotes in the stacker are stacked and stored in an upright position, moves the stacked banknotes from the rear toward the dispensing mechanism. Since the pressure of the suppression plate pressing the banknotes was adjusted appropriately, it was possible to easily return the protruding banknotes into the stacker by reversing the kick-out roller and feed-out roller.
In the case of a bill depositing and dispensing machine as shown in Publication No. 303267,
Bills are stored in the stacker from the top of the stacker and fed out from the bottom of the stacker, and the bills are stacked and stored horizontally, so if there are a large number of bills stored in the stacker, Heavy pressure is applied to the banknotes on the lower stack side, and even if the kicking and dispensing rollers are reversed as described above, the protruding bills cannot be returned to the stacker, and in the worst case, the protruding bills may jam at the stacker's dispensing port. There was a problem that it could cause problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide a payout control device for a bill depositing and dispensing machine that solves the above-mentioned problems of conventional devices.

``Means for Solving the Problems J'' In order to achieve the above object, the present invention has the following configuration. Namely, the lower opening of a stacker has a mounting plate on the upper surface on which banknotes are placed in a horizontal state. installed near the
A feeding roller that generates a bill conveying force by friction with the bill when the roller surface comes into contact with the edge of the bill,
In the bill depositing and dispensing machine that dispenses bills placed on the placing plate one by one from the lower opening, the stop position of the dispensing roller that stops when dispensing from the stacker is completed is within a specified range. If the roller stop position detection mechanism detects that the stop position of the feeding roller is outside the specified range, the bill protrudes from the lower opening. The present invention includes a pay-out mechanism that rotationally drives the pay-out roller to forcibly pay out banknotes protruding from the lower opening from the stacker by recognition.

"Function" According to the above configuration, after the dispensing operation is completed, in a state where the stop position of the dispensing roller is detected to be outside the specified range by the roller stop position detection mechanism, the bill protruding from the lower opening is not dispensed. The rollers are driven to rotate to forcibly feed out the material from the stacker. This prevents jamming at the stacker outlet.

Further, the conveyance path 6 is composed of a plurality of endless conveyance belts (shown in the figure) wound around rollers shown in the figure, but since the structure itself is the same as that of a conventional conveyance path, a description thereof will be omitted.

The placing plate 2 is raised and lowered by an elevator motor (not shown), and after receiving and taking deposited banknotes from above the stacker l, the banknotes 3 on the placing plate 2 are fed out to the dispensing route by the feeding roller 4. In this case, it is arranged to stand by at the lowest position shown in FIG.

Further, a fan-shaped detection plate 8 is provided on the shaft 4a that fixedly supports the feeding roller 4 so as to rotate coaxially with the feeding roller 4. A timing sensor 9 is provided to detect. The radius of the outer circumference of this timing sensor 9 is the same as the radius of the feed roller 4, and the outer circumference length is the same as the outer circumference length of the high friction portion 4b on the outer periphery of the feed roller 4.

The terminal end of the high friction portion 4b on the outer periphery of the feeding roller 4 is made to correspond to the other end of the outer periphery of the detection plate 8, and the high friction portion 4b and the outer periphery of the detection plate 8 correspond to each other. It is set in. This allows the timing sensor 9 to detect the position of the high friction portion 4b of the delivery roller 4.

Further, a counting sensor 10 is provided near a position slightly below the outlet 54 of the conveying path 6.

This counting sensor 0 is a sensor that detects the passage of banknotes 3 fed out from the feeding port 1a and conveyed along the conveyance path, and emits a signal for counting the number of banknotes. The rotation of the kicking roller 5 and the feeding roller 4 is stopped when the rear end of the last fed banknote 3 passes the counting sensor 10 position.

Then, the feeding roller 4. Detection plate 8. timing sensor 9

Reference numeral 24 indicates a normal pasted banknote 3 and a banknote 3 that has protruded too much from the stacker 1 during the feeding of the banknote 3 from the stacker 1.
The reject sensor detects whether or not the reject box is stored in the reject box.

Next, the operation of the payout control device in the bill depositing and dispensing machine configured as described above will be explained with reference to the flowchart shown in FIG. 3. Note that a normal feeding state is defined as a state in which the front end of the high friction portion 4b of the feeding roller 4 in the feeding direction (point B shown in FIG. 1) and the front end of the banknote 3 in the feeding direction are substantially aligned. do.

Spl: When the bill depositing and dispensing machine is activated and the normal dispensing operation is completed, dispensing control is started.

SF2: The presence or absence of the detection plate 8 is detected by the timing sensor 9, and it is determined whether the feeding roller 4 has stopped within a specified range. If the detection plate 8 is detected by the timing sensor 9, it is determined that the feeding roller 4 has stopped at a position within the specified range, and the process proceeds to SF3, and if the detection plate 8 is not detected by the timing sensor 9, the process proceeds to SF3. , it is determined that the feed roller 4 has stopped at a position outside the specified range, and the SF
Proceed to step 3.

Here, the stop position of the feed roller 4 is such that the front end in the rotational direction of the high friction portion 4b of the feed roller 4 (point B shown in FIG. 1) contacts the tip of the banknote 3 to be fed next from the stacker 1. The ideal stopping position is when you stop just before the
The position of the timing sensor 9 is set in advance so that the timing sensor 9 is installed at a position corresponding to an intermediate position of the circumference of the high friction portion 4b at that time.

SF3: Recognizing that the banknote 3 has protruded from the payout port 1a of the stacker (stacker) to such an extent that it cannot be returned to the stacker 1, the kicking roller 5 and the payout roller 4 are rotated in the forward direction, and the conveyor belt drive unit is further driven. , the protruding banknotes 3 are fed out from the feeding opening 1a in the same manner as in the normal dispensing operation, and the process proceeds to SF3.

SF3: Determine whether or not the rear end of the fed banknote 3 has passed the counting sensor 10. If it has passed, proceed to SF3, and the banknote 3
If the rear end has not passed, the state continues and waits until it passes.

SF3: Immediately stop the kicking roller 5 and the feeding roller 4 and proceed to SF3. In addition, the conveyance belt drive section continues to be driven until the banknote 3 is stored in a withdrawal reject section (not shown) as will be described later.

SF3: It is determined whether or not the dispensed banknote 3 has been rejected by the payout reject section based on the banknote detection signal of the reject sensor (shown in FIG. 2) 24. If it is determined that the banknote has been rejected, the process advances to SF3.

SF3: Assuming that the rejection of the protruding bill 3 to the dispensing reject unit is completed, the conveyor belt drive unit is stopped, and the process returns to SF3, where it is again determined whether the stop position of the feeding roller 4 is within the specified range. Ru.

spB: If it is determined in SF2 that the stop position of the feeding roller 4 is within the specified range, the kicking roller 5 and the feeding roller 4 are reversed for a predetermined period of time, and a normal bill return operation to the stacker 1 is performed.

SF3: Based on the bill detection signal of the residual sensor 11, it is determined whether or not the bill 3 remains in the outlet 13 of the stacker l, and if the bill 3 is not detected at the outlet 1a,
If the control operation ends with the assumption that the banknote 3 has been returned normally to the stacker 1, and the banknote 3 is detected at the feeding port 1a, it is recognized that the banknote 3 has protruded to the extent that it cannot be returned to the stacker 1. Then, the process returns to SF3, the kicking roller 5 and the feeding roller 4 are rotated in the normal direction, and a withdrawal reject operation is performed.

According to this embodiment, after the dispensing operation is completed, it is detected that the banknotes 3 protrude from the outlet 1a, and the banknotes are removed from the kick-out roller 5, for example.
If the bill 3 protrudes from the outlet 1a to such an extent that it cannot be returned into the stacker 1 even if the feed roller 4 is reversed, the bill 3 that has protruded out is conveyed by rotating the kick roller 5 and the feed roller 4 in the normal direction. The banknotes can be forcibly fed out to the banknote path 6, conveyed, and stored in a pasting box/box for rejecting paid banknotes, thereby preventing the occurrence of jams at the outflow port 1a of the stacker 1. In the example, even if the roller stop position detection mechanism detects that the stop position of the payout roller 4 is within the specified range, if the residual banknote 3 is detected by the residual sensor 11 at the payout port 1a of the stacker 1, , the remaining banknotes 3 are forcibly fed out from the stacker 1 by rotating the feeding roller 4. This reliably prevents jamming at the outlet 1a of the stacker 1.

"Effects of the Invention" According to the present invention, after the dispensing operation is completed, when the roller stop detection mechanism detects that the stop position of the dispensing roller is outside the specified range, the bills protruding from the lower opening are withdrawn. The rollers can be driven to rotate to forcibly feed out the paper from the stacker, thereby reliably preventing jamming from occurring at the stacker outlet.
