Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides paper sheets that are arranged in stacks such as banknotes, cards, and other paper sheets that are taken out one by one by a take-out mechanism and conveyed to a receiving section by a conveyance device. The present invention relates to a dispensing machine, and particularly to a paper sheet receiving device that can receive transported paper sheets in a receiving section in an orderly manner.

Conventionally, in this type of conveyance device, even if there is one or two conveyance means for the ejected paper sheets, the conveyance means are continuously driven at the same speed while the paper sheets are being ejected. The collected paper sheets are discharged at high speed to the stacking and holding section.

As a result, the paper sheets become uneven in the stacking storage section, and the leading edge of the paper sheets being conveyed comes into contact with the trailing edge of the previously stacked paper sheets. It can also cause jams. Therefore, when there are two conveyance means, the first conveyance means is set at high speed, the second conveyance means is set at low speed, and the second conveyance means is set at high speed.
By overlapping the front end of the following paper sheet with the rear end of the paper sheet traveling on the conveyance means, the speed of the paper sheet thrown into the stacking storage section is reduced, and the paper sheet is Dispensing machines have also been proposed that solve the above-mentioned problem by preventing the dispensing of individual coins one by one. That is, the outline of a conventional bill dispensing machine that takes out and dispenses two different types of bills in required numbers is described in the first part.
To explain with reference to the figure, there is a suction device that swings in the direction of the arrow around a fulcrum P and is connected to a suction source (vacuum pump) on the outlet side of the storage boxes 2, 2 which are arranged vertically and store a large number of banknotes 1. A head 3, a kick-out roller 4 having a kick-out portion 4a for kicking out one banknote 1 separated from a group of banknotes in the storage boxes 2, 2 by the suction head 3, and this kick-out roller 4! It consists of a pair of upper and lower delivery rollers 5 and 6 that pinch and send out the leading edge of the bill 1 pushed up from the above, and a locking member 7 that engages with the upper end of the paper group to hold down the bill when it is not taken out. A take-out mechanism 8 is provided. A conveying device 9 provided subsequent to the ejecting mechanism 8 is configured to convey the banknotes 1 ejected by the ejecting mechanism 8 above the dispensing machine, and is arranged in an endless manner between pulleys 10 and 11. It consists of a wound conveyor belt 12 and conveyor rollers 13, 13, 14, 14 that rotate in contact with the conveyor belt 12,
The bill 1 is sandwiched between the conveyor belt 12 and the conveyor rollers 13, 13, 14, and 14 and conveyed.

A curved guide member 15 for guiding banknotes 1 is provided in the upper half of the upper pulley 10, and a position close to the entrance of this guide member 15 detects two banknotes taken out in a pile. A two-bill check mechanism 16 is provided, and a removal mechanism 17 for removing two stacked banknotes is also provided downstream from the check mechanism 16.

The double-sheet checking mechanism 16 is a means for detecting double-sheet stacking based on the amount of transmitted light using a phototube or a light-receiving element, or as shown in the figure, a detection roller 16a is brought into contact with one of the conveying rollers, and the double-sheet stacking passes through. Appropriate means may be employed, such as detecting the overlapping of two sheets based on a change in the amount of movement of the detection roller 16a at that time.

The removal mechanism 17 also includes a solenoid 18 that is operated by a two-sheet check signal from the two-sheet check mechanism 16, a switching member 19 that switches the banknote feeding path of the conveyance device 9 when the solenoid 18 is operated, and this switching member. The receiving section 20 faces the feeding path converted by 19 and receives two stacked banknotes. The receiving device 21 is provided with a slow conveyance device 22 which is a conveyor belt arranged horizontally near the upper pulley 10 and has a slower feed speed than the conveyor device 9. 22
A driven roller 25 is brought into contact with a belt 24 on a pulley 23 on the front end side, and bills 1 are fed into a receiving section 26 from between this belt 24 and driven roller 25.

In the figure, reference numeral 27 denotes a flying-out prevention member for preventing the bill 1 from flying out, and the conveying devices 9 and 22 are each driven separately. Next, its operation and effect will be explained.

When a predetermined number of banknotes 1 are taken out from each storage box 2, 2 by the take-out mechanism 8 based on a delivery command, the delivery rollers 5, 6
The belt 12 of the conveying device 9 and the conveying rollers 13, 13
The belt 12 and conveyance rollers 13, 13 move the paper upward.

If there is only one bill 1, it passes through the two-bill check mechanism 16, enters between the pulley 10 and the guide member 15, changes direction, and is transferred from the end of the guide member 15 to the slow conveyance device 2.
2. The ejected banknote 1 is transferred to the driven roller 25
or the belt 24 of the slow conveyance device 22, the inertia is lost and the sheet lands softly on the belt 24 of the slow conveyance device 22. Subsequent banknotes 1 also land softly on top of the banknotes in the same manner, so that they overlap each other by a certain amount as shown in FIG. entered. Therefore, the banknotes 1 are not cluttered in the receiving section 26 and are quietly stacked one after another. When two bills 1 are sent out, the two-bill check mechanism 16 detects this, and the solenoid 1 is activated.
8 and energizes the solenoid 18 to switch the switching member 1.
9 to the position shown by the chain line, and the belt 12 of the conveying device 9
The path of the two stacked banknotes sent between the banknotes and the conveyance rollers 14, 14 is changed to the receiving section 20 side, and taken into the receiving section 20.

At the time when the taking-in is completed, the solenoid 18 is de-energized, the switching member 19 returns to the position shown by the solid line, and sends the subsequent properly taken-out bill 1 to the receiving device 21. by the way,
In the above-mentioned dispensing machine, if the bills are dispensed so that some of the bills overlap, stacking is performed normally, but in reality, there is a risk of idling during dispensing of the bills and checking means installed on the conveyance path to detect defective bills. Due to phenomena such as rejection, there is no guarantee that the banknotes will be transported on the transport device 9 at the required constant intervals.

As a result, the preceding banknotes may be ejected to the stacking holding section 26 without any subsequent banknotes on the conveying device 22, and the preceding banknotes and the following banknotes are ejected to the stacking holding section in a state where they are partially overlapped. There is a drawback that it cannot achieve the purpose of
SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a paper sheet receiving device that does not have the above-mentioned drawbacks. This invention will be explained below. The present invention relates to a paper sheet dispensing machine that takes out paper sheets stored in a paper sheet storage section one by one and ejects them to a separately provided paper sheet stacking and holding section. a first conveyance means for conveying the paper sheets taken out; and a second conveyance means for conveying the paper sheets conveyed by the first conveyance means to the paper sheet stacking and holding section and discharging them. means, a two-sheet checking mechanism for detecting that two sheets of paper taken out from the sheet storage section are stacked, and a two-sheet stack of paper sheets detected by the two-sheet checking mechanism. a removal mechanism for removing paper sheets from the first conveying means; and a sheet detection means provided in the conveyance path of the first conveying means to detect the presence or absence of conveyed sheets in the first conveying means. The conveying speed of the second conveying means is made slower than the conveying speed of the first conveying means, and when the sheet sensing means detects the conveyed sheet, the second conveying means The conveying means is driven only for a predetermined period of time.

That is, in this invention, the speed of the second conveyance means is made slower than the speed of the first conveyance means, and the banknote detection means is provided near the end of the first conveyance means on the second conveyance means side.
By configuring the second conveyance means to be driven for a predetermined period of time when the banknote detection means detects the banknote, for example, until a subsequent banknote passes through the banknote detection means in a normal conveyance state. , if the banknotes are being conveyed normally and continuously, the second conveying means is continuously driven. In addition, when the conveyance of banknotes on the first conveyance means is interrupted, the second conveyance means is stopped in response to this, and by waiting for the next banknote, two sheets of paper are taken out one on top of the other. Even when leaves are removed from the first conveyance means, the trailing end of the preceding banknote and the leading edge of the following banknote are necessarily overlapped with each other and the banknote is discharged to the stacking and holding section. In an embodiment of the invention shown in FIG. 3 corresponding to FIG.
is a banknote detection device, for example, a photoelectric device, which is provided near the end of the conveyance path of the conveyance device 9, and the detection signal DS of this banknote detection device 100 is a monostable multivibrator type timer as shown in FIG. It is input to the circuit 101.

Further, the output of the timer circuit 101 is input to the drive circuit 102 of the conveyance device 22, which is the second conveyance means, and the dispensing start command SD is input to this drive circuit 102.
It is designed to be input to a drive circuit 103 of a conveying device 9 which is a conveying means. Thus, the drive circuit 102 drives the conveying device 22 only when the dispensing start command SD is input and the output of the timer circuit 101 is input. In such a configuration, when the dispensing start command SD is input at time t1 as shown in FIG. 5A, the conveying device 9 is first driven as shown in FIG. 5B (time t1).

In this way, the banknote driven by the transport device 9 is transported, and is finally detected by the banknote detection device 100 (time T2).
At the same time, the transport device 22 is also driven via the drive circuit 102. Although the detection of the banknote is interrupted between time points T3 and T4, the drive of the conveyance device 22 is not stopped because the banknote is detected again within the set time of the time limit circuit 101 (time point T4). By the way, if the detection of banknotes is interrupted for a relatively long period of time, such as from time T6 to T8, time ζ
Since the elapsed time since then is longer than the set time of the time limit circuit 101, the drive of the transport device 22 is stopped at time T7, for example. Thus, the point in time! If a banknote is detected, the same conveying operation as described above is repeated. As described above, the paper sheet receiving device of the present invention is configured to drive and stop the conveyance in accordance with the flow of paper sheets, so that when paper sheets are discharged to the pile holding section, It is possible to reliably prevent the paper sheets from floating up, colliding, etc., and it is possible to reliably align the ejected paper sheets in the pile holding section.

In addition, in a dispensing machine that uses a counter, if the drive of the second conveying means is not stopped after the number of conveyed paper sheets reaches (set number of sheets - 1), the last sheet It is also possible to reliably hold leaves in piles.
