Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper sheet stacking device that is internally configured in an automatic transaction machine, and more particularly to a paper sheet stacking device that stably captures and stacks paper sheets such as banknotes one by one at high speed.
[0002]
[Prior art]
In general, in this type of paper sheet stacking apparatus, as shown in FIG. 8, a stacking roller 84 in which a paper sheet 82 guided from a front-side nipping and transporting roller 81 is disposed at a take-up position on the upper side of the storage box 83. And impeller 85 forcibly scraping them one by one and collecting them in the lower storage box 83.
[0003]
When the paper sheets 82 are guided to the storage box 83 in this accumulation process, the paper sheets 82 are carried in a substantially horizontal direction from the upper side of the storage box 83, and move straight forward as they are, so that the vertical position behind the storage box 83 is reached. The leading edge of the paper sheet hits the wall surface 86, and the paper sheet 82 is stopped from being carried in, and the rear end portion of the paper sheet 82 is scraped off by the impeller 85 and accumulated downward.
[0004]
[Problems to be solved by the invention]
However, as shown in FIG. 9, when paper sheets of different lengths are mixed and accumulated, the short paper sheets 82a move to the back of the storage box 83 and leave the rotational contact area of the impeller 85, Since it falls gently without being subjected to the forced accumulation action of the impeller 85, it collides with the next incoming paper sheet and induces the occurrence of jam.
[0005]
Furthermore, as shown in FIG. 10, since the paper sheets 82 are continuously accumulated on the upper surface of the already accumulated paper sheets in the storage box 83, the paper box 82 has folds or is deformed and fluffy. As a result, the storage space in the storage box 83 is narrowed, so that a specified number of sheets cannot be stored, and the storage efficiency of paper sheets is reduced.
[0006]
For this reason, as shown in FIG. 11, the paper sheets 113 are reliably stacked and guided one by one between the rotary blades 112 in the front stage of the stacking unit 111, and the paper sheets 113 are pressed by the tips of the rotary blades 112. 2. Description of the Related Art There is known a paper sheet stacking apparatus in which a stacking wheel 114 that secures a stacking space is provided and jamming is suppressed by the stacking action of the stacking wheel 114. However, in this case, it is necessary to control the rotation of the stacking wheel for guiding the paper sheets between the rotating blades, and there is a problem that the apparatus becomes large and expensive because of the large stacking wheel.
[0007]
In view of this, the present invention pays attention to the carry-in input of the paper sheets guided to the stacking unit, and the paper-sheet carry-in input can be used for the stacking operation to stably stack the paper sheets one by one. An object of the present invention is to provide a paper sheet stacking apparatus with improved paper sheet stacking performance.
[0008]
[Means for Solving the Problems]
The invention according to claim 1 is a paper sheet stacking apparatus that takes in paper sheets one by one into the stacking section and stacks them, and holds a pair of paper sheets and conveys them to the entrance of the stacking section. A conveying roller, an impeller disposed at the entrance of the stacking unit, and picking up the trailing edge of the sheets transported by the transporting roller, and pressing the sheets of the stacking unit in the stacking direction And a pressing lever that is temporarily retracted from the pressing position in conjunction with the carry-in input of the paper sheets to the stacking unit , and a contact surface with the paper sheets provided in the pressing lever is provided from the impeller. It is characterized in that it is disposed in the vicinity of the conveying roller provided upstream of the conveying .
[0009]
The invention according to claim 2 is characterized in that the pressing lever presses the leading end side of the paper sheets of the stacking portion .
[0010]
[Action and effect of the invention]
According to the present invention, when paper sheets are loaded one by one into the stacking unit and stacked, the paper sheets in the stacking unit are pressed in the stacking direction by the pressing lever before the paper sheets are loaded into a compressed state. In order to accumulate and hold, a large number of sheets can be accumulated while securing an accumulation space. In addition, when the paper sheets are carried into the stacking unit, the pressing lever is temporarily retracted from the pressing position in conjunction with the carry-in input of a single paper sheet. It is possible to obtain an integrated space without any problem. After the paper sheets are stacked, the pressing lever again presses the paper sheets of the stacking portion in the stacking direction and stacks and holds them in a compressed state to prepare for the stacking of the next paper sheet.
[0011]
As described above, since the pressing lever is configured to be pressed and retracted in the stacking unit every time the paper sheet is carried in, even when the paper sheets having different lengths are mixed and stacked, the pressing lever presses all of them. In order to avoid a collision with the next incoming paper sheet, it is possible to prevent the occurrence of a jam. Further, even if folded paper sheets and deformed paper sheets are continuously accumulated, they are not bulky because they are pressed by the pressing lever , and many paper sheets can be accumulated in this accumulation portion.
[0012]
Also , a pressing lever that is temporarily retracted from the pressing position in conjunction with the paper sheet carrying input is used, and the contact surface with the paper sheet provided in the pressing lever is disposed near the transport roller, so one sheet An interlocking pressing and evacuation structure that efficiently utilizes the paper sheet's carry-in input is obtained, and in particular, the stacking function that enhances the stacking performance of the sheet is maintained at the existing size, and the configuration is low in cost. Can be achieved.
[0013]
In addition, since it has an impeller that knocks in paper sheets in the stacking direction, the paper sheets that have been carried in by the forced stacking action of this impeller are quickly and forcibly stacked in the stacking direction so that they collide with the next loaded paper sheet. Make sure to avoid it.
[0014]
Moreover, if it sets so that the front end side of the paper sheets to collect | stack can be pressed, all the paper sheets carried in to the back of a stacking part can be pressed reliably.
[0015]
【Example】
An embodiment of the present invention will be described below in detail with reference to the drawings.
FIGS. 1 and 2 show a banknote stacking device 11, which has a stacking case 12 for stacking and stacking banknotes A one by one in the vertical direction, and a carry-in opening on the upper side of the stacking case 12. It is comprised from the banknote taking-in mechanism 14 arrange | positioned at the opening | mouth 13, and the press lever 15 which moves up and down according to the carrying-in operation | movement of the banknote A. FIG.
[0016]
The above-described bill taking-in mechanism 14 is provided with a pair of upper and lower sandwiching transport rollers 16 for horizontally sandwiching and transporting the bill A in the preceding stage, and the bill A guided here is sandwiched and transported to the carry-in port 13 of the stacking case 12. A stacking roller 17 and an impeller 18 are provided in a vertical position across the carry-in port 13. The banknotes A guided from the preceding stage are sandwiched between the stacking roller 17 and the impeller 18 and taken in one by one, and when the banknotes A are taken in, the impeller 18 forcibly knocks them down one by one. The stacking case 12 is quickly lowered and collected.
In addition, one end of the pressing lever 15 for securing an accumulation space is exposed in the accumulation case 12. The pressing lever 15 has a long plate shape extending from the outer position to the inner position of the stacking case 12, and the lever base end portion 15 a at the outer position is attached to be freely tilted via an external fulcrum pin 19. The lever tip 15b is moved up and down with the fulcrum pin 19 as a tilting fulcrum so that the fulcrum pin 19 is exposed from above in the stacking case 12.
[0017]
In addition, a pressing spring 20 is provided on the upper surface of the lever base end portion 15a, and the pressing lever 15 is constantly pressed downward by the pressing action of the pressing spring 20. The lever tip 15b that is pressed and biased presses and biases the stacked bills A in the compressed state in the stacking case 12 downwardly from the upper space. By this compression and accumulation, an accumulation space is secured in the accumulation case 12 and a large number of banknotes are accumulated.
[0018]
In this case, the lever tip 15b is set at a position slightly behind the center in the stacking case 12 and pressed, and all banknotes such as short banknotes and long banknotes that are carried into the stacking case 12 vigorously. Since A is carried in vigorously deep inside the case 12, the lever tip 15b is in a position where it can be pressed against all the banknotes, and presses the stacked banknotes reliably.
[0019]
Furthermore, the lower surface side of the lever intermediate portion has an inclined contact surface 15c that is inclined obliquely downward, and the tip of the bill A that has been carried in is in contact with the inclined contact surface 15c. By carrying in, the pressing lever 15 receiving this contact force is pushed upward with the fulcrum pin 19 as a tilting fulcrum, and the pressing lever 15 resists the pressing force of the pressing spring 20 in conjunction with the carrying input of the bill A. Then, the banknotes are temporarily retracted to a position that does not hinder the delivery of banknotes, and by securing this stacking space, it is possible to avoid the occurrence of jamming by avoiding the collision between the stacked banknotes and the loaded banknotes in the stacking case 12. Stable accumulation.
[0020]
In addition, the press lever 15 that has been pushed up in response to the carry-in input of the banknotes presses and holds the stacked banknotes in a compressed state by pressing and urging again downward from the stacking direction when the banknotes are stacked.
[0021]
As described above, the interlocking simple structure in which the pressing lever 15 efficiently presses and retracts by using the carry-in input of a single bill does not increase the size of the entire apparatus, and a bill-taking space can be obtained at low cost. It is done. Further, in the stacking case 12, even if the folded bill banknotes and deformed banknotes which are easily bulky are continuously stacked, they are not bulky because they are pressed uniformly by a plurality of pressing levers 15 arranged in parallel. Regardless, many bills can be accumulated.
[0022]
In addition, since the impeller 18 is provided at the position of the carry-in port 13 to push in the banknotes loaded in the stacking direction, the banknotes A loaded by the forced stacking action of the impeller 18 are quickly moved in the stacking direction. Forcibly stack and reliably avoid collision with the next banknote.
[0023]
The banknote stacking device 11 configured as described above will be described with reference to the banknote stacking processing operation of FIGS.
When the banknote stacking apparatus 11 is waiting to be stacked, as shown in FIGS. 1 and 2, the pressing lever 15 presses the already stacked banknotes in the stacking case 12 in the stacking direction from above and stacks and holds them in a compressed state. . For this reason, a sufficient stacking space is secured above the stacking case 12 to allow stacking of a large number of banknotes.
[0024]
In this standby state, when the banknote A is now guided to the carry-in port 13, the guided banknote A is sandwiched by the sandwiching conveyance roller 16 of the banknote taking-in mechanism 14 as shown in FIGS. At the time of horizontal loading, the tip of the bill A gently tilts against the inclined contact surface 15c on the lower surface of the pressing lever, and the pressing lever 15 tilts the fulcrum pin 19 in conjunction with the loading of the bill at this time. It is pushed upward by the fulcrum and temporarily retracts to an upper position where there is no hindrance to the incoming bill.
[0025]
As a result, a stacking space suitable for stacking is secured above the stacking case 12, and the bill A is carried in from the carry-in port 13 in a substantially horizontal direction and advances straight ahead, and the leading edge of the bill is placed on the vertical wall surface behind the stacking case 12. Will be stopped.
[0026]
At this time, as shown in FIG. 5, the banknote A that has been loaded is scraped off at the impeller 18 at the rear end side, pressed at the front end portion by the lever front end portion 15 b, and pushed downward in a plane. Forced accumulation.
[0027]
In addition, when continuously accumulating, as shown in FIG. 6, the pressing lever 15 moves up and down in conjunction with the bill A being carried in, and the pressing / retracting action accompanying the vertical movement of the pressing lever 15. Thus, the stacking operation is surely performed one by one. In particular, even when banknotes of different sizes, such as foreign banknotes, are mixed and stacked, the stacking operation can be performed reliably in the stacking case 12.
[0028]
FIG. 7 shows an electric banknote stacking device 71. The electric banknote stacking device 71 mechanically moves the pressing lever 72 up and down, and includes a solenoid 73 for driving the pressing lever 72, A carry-in detection sensor 76 disposed at the carry-in entrance 75 of the stacking case 74 and driving the solenoid 73 in synchronism with the detection signal from the carry-in detection sensor 76 allows the pressing / retracting operation synchronized with the carry-in bill A to be performed. In this case, it is possible to obtain a stacking operation that is not affected by the deformation of the banknotes that are brought in or the poor paper quality.
As described above, the bills accumulated in the stacking case are pressed in the stacking direction in the stacking direction by the pressing lever before the banknotes are loaded into the stacking case, so that the stacking is sufficient in the upper part of the stacking case. A large number of sheets can be collected while securing a space. In addition, when the banknotes are loaded into the stacking case, the pressing lever is temporarily retracted from the pressing position in conjunction with the loading of the banknotes, so that a stacking space suitable for stacking is accurately placed in front of the banknotes to be loaded. Is obtained. After the banknotes are stacked, the pressing action by the pressing lever is again performed as the banknotes are carried in, and the banknotes are stacked and held in a compressed state, and the banknotes are stacked one by one by repeating this pressing and evacuation.
[0029]
In this way, because the pressing lever is configured to be pressed and retracted in the stacking case every time a banknote is loaded, it is possible to avoid a collision between an already-stacked banknote and the next banknote, thereby preventing jamming in the case. can do. Further, even if folded bills and deformed bills are continuously accumulated, the bills are surely pressed one by one with each other, so that many bills can be accumulated without being bulky in the case.
[0030]
In addition, because of the interlocking pressing and retracting structure that efficiently uses the carry-in input of a single banknote, the cost can be reduced with a simple configuration, and the stacking performance of banknotes can be improved while maintaining the existing size. Moreover, all the banknotes carried into the back of the stacking case in order to forcibly stack the banknotes quickly by the forced stacking action of the impeller that knocks the banknotes in the stacking direction, and to press the leading end side of the stacked banknotes It can be surely pressed correspondingly. Furthermore, if a stacking operation that mechanically presses and retracts in conjunction with the banknote stacking operation is performed, a stacking operation that is not affected by the deformation of the banknotes or the paper quality can be obtained.
