Abstract

PURPOSE:To enable it to accurately count the number of paper sheets even if stacking is continued in succession after jam handling by installing a conveying means which conveys the paper sheets entered in a conveying passage at the side where a paper jam occurred, to a stack part against the resistance force of the jammed paper sheets. CONSTITUTION:When a jam occurred, a jam detecting sensor 20 detects this jam occurrence, and a selector means 13 selects a conveying passage. With this changeover, such a possibility that paper sheets might be conveyed to the conveying passage at the side where the jam occurred is prevented. The paper sheets fed to the conveying passage at the side the jam occurred before this selector means 13 is selected are conveyed to a target spot by conveying means 15, 16 strong in conveying force against resistance of the jamed paper sheets. Consequently, the number of paper sheets being counted by a sheet count sensor 19 comes to show the number of the paper sheets fed to the conveying passage at the side where the jam occurred accurately.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet handling mechanism, and in particular, when a jam occurs during conveyance of paper sheets, the paper sheets conveyed to the jam occurrence part are This invention relates to a paper sheet handling mechanism that can accurately count the number of sheets.

[Conventional technology]

There are two methods for stacking paper sheets in conventional paper handling mechanisms:

The first method is to create a temporary separation between already stacked paper sheets and newly stacked filter paper sheets, as described in Japanese Utility Model Application Publication No. 61-164579. A bottom plate is provided, the paper sheets are stacked on the bottom plate, and after the stacking operation is completed, the bottom plate is released to merge the already stacked paper sheets with the currently stacked paper sheets.

The second method is to stack new paper sheets directly on top of the already stacked paper sheets without providing the bottom plate in the first method.

The first method is useful for devices that need to accurately determine the number of paper sheets stored in the storage section from the paper sheet feeding section. In particular, in devices where the number of paper sheets must be accurately determined, even if a jam occurs in the stack section, the operator must check the stack of paper sheets on the bottom plate, the jammed paper sheets, and the paper in the conveyance path. It is only necessary to remove the paper sheets from the stack and feed the paper sheets again from the feeding mechanism section.Therefore, there is an advantage that there is no need to re-count the paper sheets that were previously stacked.

In addition, according to the second method described above, when stacking paper sheets, there is no need to separate and stack paper sheets for each stacking operation, so a large amount of paper sheets can be stacked in a short time by the feeding unit. It has the advantage that it can be sent to the stack section from there.

[Problem to be solved by the invention]

In the first method described above, the problem is that it takes a lot of time, especially when sending a large amount of paper sheets, because it is necessary to perform a storage operation every certain number of sheets, and it is also necessary to stop the feeding operation each time. was there.

In addition, in the second method described above, the paper sheets to be stacked this time are placed directly on top of the previously stacked paper sheets, so it is not possible to separate them. For devices that require accurate identification of the number of sheets in a stack, if a jam occurs in the stack,
There was a problem in that the operator had to take out all the paper sheets including those that had been stacked before, transport them again from the feeding section, and re-count them. In particular, no consideration was given to the fact that if a jam occurs when a large amount of paper sheets are stacked, it will take a long time to recover.

The present invention is capable of stacking a large amount of paper sheets continuously, and even if a jam occurs in the stacking section or the conveyance path leading to the stacking section, the sheets will not be conveyed to the stacking section or the conveyance path leading to the stacking section. By providing a paper sheet handling mechanism that can accurately count the number of paper sheets that have been loaded, even if a jam occurs while feeding a large amount of paper sheets, the operator's effort to recover from the jam can be reduced. Furthermore, the present invention aims to shorten the time required to feed a large amount of paper sheets from a feeding section to a stacking section.

[Hth way to solve the problem]

The paper sheet handling mechanism of the present invention includes a jam detection sensor that detects the occurrence of a jam in a stack of paper sheets, and a conveyance path on the side where the jam occurs when the jam detection sensor detects the occurrence of a jam. a switching means for switching the conveyance path so as not to convey the paper sheets, a sensor for counting the number of paper sheets provided between the switching means and the jam detection sensor, and a sheet count sensor provided between the switching means and the jam detection sensor; When the conveyance path is switched so that the paper sheets are not conveyed to the paper path, the paper sheets that have already entered the conveyance path on the side where the jam has occurred are conveyed to the stacking section against the resistance of the jammed sheets. It is characterized by having the means.

Here, the jam detection sensor may be provided between the sheet stacking section and the number counting sensor, or may be provided on the general conveyance path.

[Effect]

According to this invention, when a jam occurs, the jam detection sensor detects the occurrence of the jam, and the switching means switches the conveyance path. This prevents paper sheets from being conveyed to the conveyance path on the side where the jam occurred. The paper sheets sent to the conveyance path on the side where the jam occurred before the switching means is switched are conveyed to the destination by the conveyance means with a strong conveying force against the resistance of the jammed sheets. Therefore, the number of paper sheets counted by the sheet number counting sensor accurately indicates the number of paper sheets sent to the conveyance path on the side where the jam occurred.

FIG. 1 is an explanatory diagram showing the structure of a bill payout stack mechanism 4 provided at the top of the ten thousand yen box shown in FIG. 2. FIG. 1st
In the figure, reference numerals 10, 11, and 12 are conveyor belts arranged at opposite positions, and the banknotes 27 are held between conveyor belts 0 and 12 and conveyor belts 10 and 11 and conveyed to the right in the figure. . Reference numeral 13 denotes a shutter that swings around a shaft 14 by a drive mechanism (not shown), and is used to transport banknotes 27, which are conveyed from the left side of the figure, to the side held between conveyor bells (10 and 12) or to the side of the ten thousand yen box (1). This is to guide you to the side. Reference numerals 15 and 16 denote rubber rollers that are driven by the same power source as the conveyor belt 12 and are in contact with each other at a certain pressure, and feed the banknotes guided toward the 10,000 yen box 1 by the shutter 13 into the 10,000 yen box 1. It is for. Furthermore, 17 is a guide that guides the banknotes sent by rubber rollers 15 and 16 so that they are stacked. Reference numeral 18 designates a plate as a receiver for receiving banknotes in order to stack incoming banknotes. This support plate 18 is configured to be movable in the vertical direction in the figure by a drive source (not shown). 19 optically detects the passage of banknotes, and
This is a number counting sensor for counting the number of banknotes sent to the bank.

This sheet number counting sensor 19 is provided between the branch point of the conveyance path by the shutter 13 and the nipping point of the rubber rollers 15 and 16. Further, 20 is a jam detection sensor, which is installed near the gripping point of the rubber rollers 15 and 16 of the ten thousand yen box 1, and if the optical path of the jam detection sensor 20 is blocked for a certain period of time or more, the jam detection sensor 20 will be stuck in the ten thousand yen box 1. It is determined that a jam has occurred. Reference numeral 2■ is an upper end detection sensor for detecting the upper end of a large number of stacked banknotes 2B. Also, 2

These roller guides are used to feed out the sheets one by one to the left in the figure.

Next, the operation when loading banknotes into the 10,000 yen box 1 and the 1,000 yen box 2 will be described using FIG. Bills of 10,000 yen and 1,000 yen placed in the cassette 3 are fed out one by one by a bill feeding stack mechanism 6 provided at the top of the cassette 3, passed through a conveyance path 9, and sent to the discrimination section 7 for discrimination. Part 7
The denomination is determined at . As a result of denomination determination, 10,000 yen banknotes and 1,000 yen banknotes were determined by the banknote feeding and stacking mechanism 4.5.
As a result, the 1000 yen box I and the 1000 yen box 2 are stacked. As a result of the denomination determination, those that cannot be determined to be 1,000 yen banknotes or 10,000 yen banknotes are transported to the reject box 8. If a jam occurs in the bill dispensing and stacking mechanism 4 of the 1,000 yen box 1 or the bill dispensing and stacking mechanism 5 of the 1,000 yen box 2 during this conveyance operation, the number of bills in the jammed box will be accurately counted as described later. Therefore, the operator can arrange the jammed banknotes, return them to the original box, set the banknotes remaining in the conveyance path 9 in the cassette 3, and then perform the loading operation.

Next, an outline of the operation of the feeding stack mechanism 4 will be explained using FIG. 2.

The banknotes 27 clamped by the conveyor bells l-10 and II are guided by the shutter 13 and proceed to the clamping point side of the rubber rollers 15.16, and then proceed along the guide 17 by the conveyance force of the rubber rollers 15.16, and the banknotes 27 that have already been stacked are Banknotes 2
Stacked on top of 8. As stacking is performed continuously, the upper end position of the banknotes 28 rises, and the upper end detection sensor 21
When detects the upper end of the banknotes 28, the plate 18 lands on the receiver and is controlled so that the upper end of the stacked banknotes 28 is always at a constant position. In this way, the space necessary for stacking new banknotes 28 is secured. Further, when the banknotes 28 are fed out, the plate 18 of the receiver rises, and the stacked banknotes 28 rise and come into contact with the rollers 22, and after stopping, the roller guide! 22.23° 24, 25.26, and are fed out one by one and conveyed to the right in the figure by a conveyor belt 10.11. At this time, the shutter 13
It is switched to the conveyance path side consisting of 0.12, and the banknote 2
8 is transported to the next stage by this transport path.

Next, the operation of counting the number of banknotes will be explained using FIG. 2 and FIG. 3, which is an explanatory diagram at the time of a jam.

In FIG. 2, the front end of the banknote 27 that is sent to the 10,000 yen box 1 side by the carrying force of the carrying bell) 10. , - The trailing edge passes the number counting sensor 19 and is counted. Thereafter, the banknotes 27 are fed into the ten thousand yen box 1. At this time,
The jam detection sensor 20 detects the presence of banknotes. but,
The jam detection sensor 20 is arranged at a position where the presence of the banknote 27 is not detected when the transported banknote is stacked on top of the banknote 27.

Therefore, the jam detection sensor 20 is configured not to detect the presence of banknotes continuously for a certain period of time or more when the banknotes are inserted normally.

Next, when a jam occurs, the space for stacking is blocked as shown in FIG. 3, and eventually the rear end 29 of the jammed bill blocks the jam detection sensor 20 for a certain period of time or more. This allows the occurrence of a jam to be detected. When the occurrence of a jam is detected, a control unit (not shown) switches the shutter 13 so that the subsequent banknotes 27 are moved to the conveyor belt 10.1.
The material is transported along a transport path consisting of two parts.

Here, the problem is as shown in Figure 3, the shutter 1
This is a case where the front end of the banknote 30 enters the conveyance path on the side of the 10,000 yen box l before the banknote 3 is switched. In this case, if the banknote 30 cannot pass the detection position of the number counting sensor 19 due to the resistance of the jammed banknote, when the operator feeds the banknote 30 into the ten thousand yen box 1 when removing the jam, the banknote count value and the ten thousand yen box 1 The number of banknotes in the banknotes does not match. In this embodiment, in order to prevent this, by the time the shutter 13 is switched due to jam detection, the number of bills that have entered the conveyance path on the 10000 yen box L side will overcome this resistance regardless of the state of the jam, and will definitely Since the rubber rollers 15, 16 are configured to have enough conveying force to send out the bills beyond the nipping point of the rubber rollers 15, 16, the count value by the number counting sensor 19 and the number of bills in the 10,000 yen box 1 are made to match. be able to.

Note that the above embodiment has been explained on the assumption that the distance from the shack 13 to the rubber rollers 15 and 16, which are the final conveyance means for sending banknotes to the ten thousand yen box 1, is short; however, if this distance is long, The distance from the sensor 19 to the final conveyance means can be increased. In such a case, there is no need to feed the banknotes 30 into the ten thousand yen box 1, which have entered the conveyance path on the ten thousand yen box 1 side due to a delay in switching the shutter 13 during a jam. In this case, banknote 3
It is sufficient to provide the conveying means with a conveying force sufficient to allow the number 0 to pass through the sheet count sensor 19. In this case, in order to prevent the operator from making a mistake when removing the jam, it is ensured by clearly indicating that all banknotes present in the conveyance path on the 10,000 yen box 1 side after the conveyance path switching point by the shutter 13 are already counted banknotes. Become.

In addition, when the distance to the bill dispensing and stacking mechanism 4 is long, by providing a jam detection sensor in the conveyance path leading to the bill dispensing and stacking mechanism, not only jams in the bill dispensing and stacking mechanism but also jams in the conveyance path can be detected. Even if this occurs, it is possible to accurately count banknotes.

〔Effect of the invention〕

According to the present invention, even if a jam occurs in the stacking mechanism, the stacked banknotes can be accurately counted after the jam is removed. Therefore, in a mechanism that needs to convey and stack a large amount of paper sheets and accurately count the number of sheets, the following effects are achieved.

(1) Paper sheets can be counted accurately even if stacking is continued after jam processing. In other words, including paper sheets that have been stacked for a long time,
There is no need to re-stack paper sheets from the beginning, and compared to conventional technology, the operator's effort can be significantly reduced.

(2) A partition is provided between the already stacked paper sheets and the newly stacked paper sheets, and when a certain number of paper sheets are stacked without jamming, these sheets are placed in the storage box. Compared to a method in which the number of counts is determined by storing and repeating this process, the present invention enables continuous stacking, which has the effect of significantly shortening the processing time.
