Description

TECHNICAL FIELD The present invention relates to a stacking device for stacking a predetermined number of paper sheets such as banknotes, securities, etc., and particularly, a stacking apparatus capable of stacking paper sheets with their edges aligned. Regarding the device.

"Prior Art" As a stacking device having means for aligning the ends of paper sheets to be stacked, there is known one shown in Japanese Patent Laid-Open No. 59-78066.

The paper sheet stacking device described in this publication collects the paper sheets sent to the stacking unit one by one by a conveyor belt or the like.
It is beaten with a beat-off fork and accumulated on the backing plate. A vibration plate is provided on a side portion of the stacking portion located in the width direction of the paper sheet, and the vibration plate is vibrated by an eccentric cam of a vibration plate driving motor to generate a side portion of the paper sheet. By repeatedly striking the paper, the side parts of the paper sheets that were knocked off were aligned.

[Problems to be Solved by the Invention] In such a conventional paper sheet stacking apparatus, since the diaphragm is vibrated by the dedicated drive mechanism, the frontage becomes wider when the paper sheets are fed, It is difficult to control the vibration of the vibrating plate such as hitting the end of the paper sheet when the paper sheet falls on the receiving plate, and there is a complaint that the timing must be adjusted by complicated control. In addition, there is a complaint that the mechanism for vibrating the diaphragm is complicated.

The present invention has been made in view of the above circumstances, and an object thereof is to simplify the structure and control of the alignment mechanism.

"Means for Solving the Problem" In the paper sheet stacking apparatus of the first invention, an aligning plate that can be swung substantially along a horizontal plane so as to hit an end portion of the stacked paper sheets is provided on the stacking unit side. In order to solve the above problems, the aligning plate is provided on the stacking unit side by swinging the aligning plate by a transmission mechanism that is connected to a drive mechanism that swings the knock-off fork. A biasing member for biasing is attached, and a pressing member that pushes the aligning plate in a direction away from the accumulating portion against the biasing force of the biasing member is brought into contact with the aligning plate, and the pressing member reciprocates by the transmission mechanism. By moving, the aligning plate is swung so as to hit the end of the paper sheet.

In the paper sheet stacking device of the second invention, a cutout window communicating with the outside is provided outside the aligning plate, a transparent lid is provided so as to be openable and closable so as to cover the cutout window, and the aligning plate is provided on the transparent lid. The plate was swingably attached.

[Operation] In the paper sheet stacking apparatus of the first invention, the aligning plate provided on the side of the stacking unit is slung by using the motion of the drive mechanism of the unit, so that the bill is fed. At this time, the alignment plate swings in synchronization with the movement of the fork that knocks it off. Therefore, in this paper sheet stacking device, the aligning plate swings at a cycle that coincides with the timing at which banknotes are fed in, without providing a means for controlling the timing of swinging the aligning plate. Further, since the aligning plate is biased toward the stacking portion side by the biasing member, wide sheets are stacked while the operating angle of the aligning plate is set to match the narrow width of the sheets. However, because the width is wider, the aligning plate operated by the urging force of the urging member escapes, so that it is possible to prevent the paper sheets from being overstruck.

Further, in the paper sheet stacking apparatus of the second invention, the notch window provided on the side of the stacking section is closed by the transparent lid, so that the inside of the stacking section can be visually recognized from the outside. Further, in the paper sheet stacking apparatus of the third invention, since the aligning plate is attached to the transparent lid, when the transparent lid is rotated when the cutout window is opened, the aligning plate is separated from the cutout window together with the transparent lid. .

The sorting forks 9 and 10 also have a function of pressing the bills on the receiving plate 8 which are displaced downward with the pressing edges 9a and 10a to prevent the disorder of the stacking state.

The hit-off unit 3 is composed of a hit-off fork 11 arranged above the stacking unit 2 and a drive mechanism 12 for swinging the hit-off fork 11. The strike-off fork 11 swings as shown by an arrow a in FIG. 1 and strikes the bill fed from the conveying path 1 onto the receiving plate 8 of the stacking unit 2. The knock-off fork 11 has a thin rod shape, and a link portion 14 is formed at the rear end thereof so as to bulge in a substantially right angle direction. Further, the rear end of the knock-off fork 11 is rotatably mounted on a horizontal rotary shaft 13. The drive mechanism 12 is connected to the link portion 14 of the hit-off fork 11. The drive mechanism 12 includes a drive shaft 15 provided behind the rotary shaft 13, a link 16 connected to the drive shaft 15, the link 16 and a link portion 14 of the knock-off fork 11.
And a connecting arm 17 for connecting the drive shaft 15 with a stepping motor (not shown).
The fork 11 is swung by swinging forward and backward.

As shown in FIG. 3, a cutout window 19 is formed in the frame 18 surrounding the paper sheet stacking device 53 so as to be located on one side of the stacking unit 2. And this notch window 19 part,
Covered by a transparent lid 20. The transparent lid 20 is rotatably supported by support fittings 21 and 22 attached near the cutout window 19, and the cutout window 19 can be opened and closed as needed. A stopper 23 for restricting the opening angle of the transparent lid 20 is provided at a position near the support fitting 21 of the frame body 18.

Further, in the vicinity of the stopper 23, a pin that, when the transparent lid 20 is displaced to the open position, enters from the notch 25 of the transparent lid 20 and pushes the aligning plate 30 described later to bring it into a state along the transparent lid 20.
26 are projected.

An alignment plate 30 forming the alignment mechanism 4 is provided on the inner surface side of the transparent lid 20. The alignment mechanism 4 is shown in FIGS.
As shown in the figure, the aligning plate 30 and the transmission mechanism 31 are roughly configured, and the aligning plate 30 is arranged so as to be located on a side portion of the stacking unit 2. The aligning plate 30 has a thin plate shape, and the entire shape is a substantially T shape. This alignment plate 30
Is a support metal fitting 32, 32 attached to the transparent lid 20,
It is supported so as to be swingable in a substantially horizontal direction as indicated by an arrow b in FIG. Then, it is biased by a spring (not shown) in a direction away from the transparent lid 20.

As shown in FIG. 1, the transmission mechanism 31 includes a first parallel link 35 attached to the drive shaft 15 of the knock-off unit 3 and a second parallel link 36 rotatably attached to the rotary shaft 13. An arm 37 connecting the parallel links 35 and 36
And is constituted by. A pressing roller 33 is attached to the end of the arm 37 on the second parallel link 36 side. The pressing roller 33 regulates the position of the aligning plate 30 in the swing direction b, and is in contact with the inner surface side of the rear end of the aligning plate 30. The pressing roller 33 reciprocates in a direction substantially orthogonal to the swing axis C of the aligning plate 30 according to the operation of the arm 37. Further, the pressing roller 33 is attached so as to be rotatable in its movement direction.

 Next, the operation of the paper sheet stacking device 53 will be described.

The banknotes sent from the transport path 1 are detected by a timing sensor (not shown) provided in the transport path 1 and then jump into the stacking unit 2. Then, the drive shaft 15 of the hit-off unit 3 is rotated forward by the output from the timing sensor, whereby the hit-off fork 11 is swung downward. Then, the banknotes are dropped onto the receiving plate 8 by the fork 11. On the other hand, due to the rotation of the drive shaft 15, the transmission mechanism 31 of the alignment mechanism 4 is also swung, and the pressing roller 33 moves to the rear end side of the aligning plate 30 as shown by the alternate long and short dash line in FIG. Then, the aligning plate 30 is gathered by the urging force of a spring (not shown).
Rock to the side. Then, the banknotes that have entered the stacking unit 2 are brought closer to the side guide surface 38 side of the stacking unit 2 by the aligning plate 30.

When the banknotes that have entered the stacking unit 2 fall into a predetermined position on the receiving plate 8 in this way, the drive shaft of the knocking-off unit 3 is driven.
15 is rotated in the reverse direction, and the knock-off fork 11 is swung upward. Then, as the drive shaft 15 rotates, the transmission mechanism 31 of the alignment mechanism 4 also swings, and the position of the pressing roller 33 is displaced to the front side of the aligning plate 30 as shown by the solid line in FIG. Then, the aligning plate 30 is returned to the transparent lid 20 side against the biasing force of the spring.

When a predetermined number of banknotes are stacked on the receiving plate 8 in this manner, the receiving plate 8 is lowered and the stacked banknotes are sent to the bundling unit 55 for winding a band. When the receiving plate 8 is lowered, the sorting forks 9 and 10 rotate to the upper side of the receiving plate 8 to temporarily hold the bills sent thereto. Further, the bills on the receiving plate 8 are pressed by the pressing edges 9a, 10a of the sorting forks 9, 10 to prevent the banknotes from being disturbed.

In this way, during the banknote stacking operation, if it becomes necessary to remove fractional banknotes that have not reached the predetermined number, or jam banknotes that have occurred in the stacking device, open the transparent lid 20 and through the cutout window 19. These bills can be removed. When the transparent lid 20 is opened, the aligning plate 30 attached to the inside of the transparent lid 20 is pushed by the pin 26 to be along the transparent lid 20 as shown in FIG. 2, and the cutout window 19 becomes large. be opened.

As described above, the banknote stacking device 53 is provided with the aligning plate 30 that horizontally swings on the side of the stacking unit 2.
Since the aligning plate 30 is swung by the transmission mechanism 31 attached to the drive shaft 15 of the knocking-down unit 3, the aligning plate 30 swings in synchronization with the movement of the fork 11 that knocks down the fed bills. Thus, the cycle in which the banknotes are sent and the cycle in which the aligning plate 30 swings match. Therefore, in the banknote stacking device 53, the aligning plate 30 moves outward when the banknotes are thrown in without any special control to widen the frontage of the stacking unit 2 and after the banknotes enter the stacking unit 2. The operation of hitting the ends of the banknotes with the aligning plate 30 to align them can be performed without providing a special control mechanism, and the control of the aligning mechanism 4 can be simplified. Further, in this stacking device 53, the driving mechanism 12 of the knocking-down mechanism 3 is used to make the aligning plate 30 of the aligning mechanism 4.
Since the device is swung, a new drive device is not required, and the device structure can be simplified.

Further, in this paper sheet stacking apparatus 53, a spring for urging the stacking plate 30 toward the stacking unit 2 is attached to the stacking plate 30, and the stacking plate 30 is pushed in a direction away from the stacking unit 2 against the biasing force of the spring. Since the pressing roller 33 is brought into contact with the inner surface of the aligning plate 30, and the pressing roller 33 is reciprocated by the transmission mechanism 31 continuously provided to the drive shaft 15 of the unit 33,
Even if a wide banknote (for example, 5,000 or 10,000) is accumulated while the operation angle of the alignment plate 30 is set to correspond to a narrow banknote (for example, 1,000 banknotes), the width of the banknote A large amount of
The aligning plate 30 operating only by the spring force escapes. Therefore, according to this paper sheet stacking device 53, if the operation angle of the aligning plate 30 is set to correspond to the narrow width of the thousands of notes, the banknotes will not be damaged even when the operation of collecting the wide notes of 5,000 or 10,000 is wide. Since it can be performed without giving, there is an advantage that no adjustment is required at the time of denomination exchange and setup work is reduced.

Further, in this paper sheet stacking device 53, the cutout window 19 provided on the side of the stacking unit 2 is closed by the transparent lid 20, so that the situation of the stacking unit 2 can be visually recognized from the outside.

In addition, in this paper sheet stacking device 53, the aligning plate 30 has a transparent lid.
Since it is attached to the cutout window 19, the aligning plate 30 also separates from the cutout window 19 when the transparent lid 20 is rotated when the cutout window 19 is opened. Therefore, the paper sheet stacking device 53 has an advantage that operations such as removing jammed bills performed through the cutout window 19 are easy.

Moreover, in this paper sheet stacking device 53, a pin 26 that pushes the rear end of the aligning plate 30 attached to the inner surface of the transparent lid 20 when the transparent lid 20 is opened is erected on the outer surface of the frame body 18, so that it is transparent. lid
When the opening 20 is opened, the aligning plate 30 is in contact with the inner surface of the transparent lid 20. Therefore, the paper sheet stacking device 53 has an advantage that the aligning plate 30 does not get in the way during the work performed through the cutout window 19 such as the work for removing jammed paper money.

"Effects of the Invention" As described above, the paper sheet stacking device of the first invention is
An aligning plate that swings substantially in the horizontal plane is provided on the side of the stacking unit, and this aligning plate is a device that is swung by a transmission mechanism that is connected to a drive mechanism that swings the knock-off fork. The aligning plate swings in synchronism with the movement of the knock-off fork that is controlled to knock down the banknotes that have been dropped. Therefore, in the paper sheet stacking apparatus of the present invention, the cycle of feeding the paper sheets and the cycle of swinging the aligning plate can be matched with each other without providing a special control mechanism, and the control is simplified. be able to. Further, in the integrated device of the present invention, since the aligning plate is swung by utilizing the drive mechanism of the knocking-down mechanism, it is not necessary to provide a new drive device, and the device structure can be simplified. A biasing member that biases the aligning plate toward the stacking unit is attached to the aligning plate, and a pressing member that pushes the aligning plate away from the stacking unit against the biasing force of the biasing member contacts the aligning plate. Since this pressing member is a device which can be reciprocated by the transmission mechanism, even if the stacking work of wide paper sheets is performed with the operating angle of the aligning plate set corresponding to the narrow paper sheets. The wider the bill, the more the aligning plate that is operated only by the spring force escapes. Therefore, according to the paper sheet stacking apparatus of the present invention, it is not necessary to adjust the operation angle of the aligning plate even when the stacking work of paper sheets having different widths is sequentially performed, and the load of the setup work can be reduced.

In the paper sheet stacking device of the second invention, a cutout window communicating with the outside is provided on the outside of the aligning plate, and a transparent lid is provided so as to be openable and closable so as to cover the cutout window portion. Since the aligning plate is a swingably mounted device, there is an advantage that the condition inside the stacking unit can be visually recognized from the outside.

In addition, in the paper sheet stacking device of the present invention, since the aligning plate is attached to the transparent lid, when opening the cutout window,
When the transparent lid is rotated, the alignment plate also separates from the cutout window. Therefore, the paper sheet stacking apparatus of the present invention has an advantage that it is easy to remove jammed paper money from the cutout window.
