Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention sequentially receives and holds paper sheets, such as banknotes, that are successively carried out from a transport path between the blades of a rotating impeller and sequentially stores them in a stacking chamber. The present invention relates to improvement of a paper sheet stacking device for stacking discharged sheets.

[Technical background of the invention and its problems]

For example, in a banknote sorter or the like, the banknotes that are collectively supplied are taken out one by one and discriminated, and the reusable banknotes (genuine banknotes) and the reusable banknotes (unbanked banknotes) are separately accumulated. A predetermined number of sheets, for example, 100 sheets, are stored separately.

Recently, in this type of device, a stacking device is being developed in which the front and back of banknotes are automatically stacked in a stacked state so that a sealing operation, which is a post-processing step, can be easily performed.

In this type of device, the 10,000-yen ticket P ₁ , the 5,000-yen ticket P ₂ ,
Since it is necessary to handle bills P of different sizes, such as a 1,000-yen bill P ₃ , and to convey the bills in a state where the conveyance pitch is shortened in order to improve the processing capacity, the bill conveyance path 1 is usually the fifth
As shown in the figure, the maximum size of the handled banknotes, that is, the size width W set to be slightly larger than the size of the 10,000-yen note P _{1 in} the longitudinal direction, and the banknotes P ... It is configured to be taken out and conveyed in the direction.

Then, the banknotes P which have been conveyed back to the stacking direction in the stacking chamber 2 via the front and back reversing means (not shown) ...
In the drawing, the case of a 5000 yen bill P ₂ is shown), and the front and back are arranged at the time of stacking by reversing by 180 degrees around the central portion in the width direction of the bill transport path 1.

However, in the case of such a configuration, there is no problem if the largest size bill, that is, the 10,000-yen bill P ₁ is inverted, but a bill of a smaller size, that is, the 5,000-yen bill P ₂ , When the 1,000-yen bill P ₃ or the like is reversed, the bill P is flipped around a position displaced from the central portion in the longitudinal direction, so that the longitudinal end face is separated from the reference guide portion 1 a of the bill conveying path 1. As a result, the longitudinal direction becomes uneven, and the stacking state is disturbed. As it is, as shown in FIG. 6, it is not possible to perform the banding with the band 3 in the state where the banknotes P ₂ ... It was a big obstacle to get them to do it.

[Object of the Invention]

The present invention has been made based on the above circumstances, and its object is to arrange the paper sheets in a state in which one end surfaces along the direction orthogonal to the conveying direction are arranged in a neat manner while having a relatively simple configuration. An object of the present invention is to provide a stacking device for paper sheets that can be stacked.

[Outline of Invention]

In order to achieve the above-mentioned object, the present invention provides a stacking unit that receives and sequentially stacks paper sheets sequentially discharged from a transport path, and a stacking unit when a predetermined number of paper sheets are stacked in the stacking unit. A separator that temporarily collects the paper sheets that have entered and accumulated in the accumulating unit and that is subsequent to the paper sheets that are accumulated in the accumulating unit, and transfers the temporarily accumulated paper sheets into the accumulating unit; The end faces of the sheets stacked on the separator and the end faces of the sheets stacked on the separator are intermittently biased and stacked in the stacking unit and on the separator. An aligning member for simultaneously arranging the paper sheets accumulated in the stack and on the separator, and when the paper sheets accumulated on the separator are transferred to the accumulating portion by retracting the separator from the accumulating portion.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, 1 is a banknote transport path for transporting banknotes P as paper sheets, and 4 and 4 receive and hold the banknotes P sequentially carried out from the transport path 1 between the blades 4a, 4a, and a stacking chamber 2
This is an impeller for sequentially discharging and accumulating paper in the accumulating chamber 2 by rotating in the direction. These impellers 4 and 4 are separator rotating shafts 5.
As shown in FIG. 1, the engaging wheel portion 7 is rotatably supported on the outside of the bearing via bearings 6 and 6, and is spirally curved in a rotational direction protruding from the outer periphery of the coupling wheel portion 7 in the radial direction. , Which is composed of a large number of blades 4a, and is meshed with a gear 8 provided on the coupling wheel portion 7 and a gear 9 driven to rotate by the electric motor 10 so that the gear 8 is rotated at a constant speed in the direction of the arrow in FIG. It has become.

Reference numerals 11 and 11 denote a pair of left and right separators arranged on both left and right sides of the impellers 4 and 4 as shown in FIG. 1. These separators 11 and 11 are pivotally attached at one end to the separator support bodies 12 and 12 of the separator rotation shaft 5. The lever portion 1 having the rotation fulcrum and extending in the direction orthogonal to the separator rotation shaft 5.
4 is a cam engagement portion 15 composed of a rotatable roller rotator.
And a receiving portion 16 for dividing the designated number of blades, which is located inward of the blade outer shape of the impellers 4 and 4 at the separator standby position and extends in the protruding direction of the blades 4a and 4a. Of the rotary lever, and the separators 11 and 11 composed of the rotary lever are separator support members 12 and 12.
The spring force of a coil spring (not shown) whose one end is fixed and the other end is adjusted and fixed to a position from the lever fulcrum is urged in a direction to engage with the cutout portion 5a of the separator rotation shaft 5.

The separator receiving portion 16 is the blade 4 of the impellers 4 and 4.
The curved shape is substantially the same as the shapes of a and 4a.

Further, the rotary shaft 5 of the separators 11 and 11 is composed of a hollow shaft as shown in FIG. 1 in which the impellers 4 and 4 are rotatably supported, and is inserted and supported in the hollow shaft to support the impeller drive unit (shaft). It is connected via a clutch mechanism 21 to a drive shaft 20 that rotates by receiving power from the meshing gears 18, 19) on the end side. The clutch mechanism 21 uses a two-position spring clutch that can stop the separators 11 and 11 at two positions, that is, a standby position and a discharge receiving and accumulating position.

Further, the bottom of the stacking chamber 2 is composed of a stacking moving carrier 22 as a receiving member that is displaced by a carrier transferring means (not shown), and transfers the specified number of stacked banknotes P ... To the next step. ing. The carrier 22 is composed of a plurality of L-shaped members 23 having a horizontal receiving portion 23a and a supporting portion 23b for backing up one short side of the banknote stack P ... It is in a nested state with the separators 11, 11.
The banknotes P ... Guided into the stacking chamber 2 are the supporting portions 2
By bringing one end face in the lateral direction into contact with 3b ..., they are stacked in a state in which they are aligned in this direction.

On the other hand, as described above with reference to FIG. 5, the transport path 1 has the largest size bill among the handled bills P, that is, the 10,000-yen bill P.
_The width W is set to be slightly larger than the dimension of the banknote _{1 in} the longitudinal direction, and the banknotes P are taken out and conveyed in the lateral direction with one end surface in the longitudinal direction as the reference of the reference guide portion 1a. Then, the accumulating chamber 2 through the front and back reversing means (not shown).
Banknotes P conveyed back to the stacking direction in ...
(In FIG. 5, the case of a 5000-yen note P ₂ is shown) is inverted by 180 degrees about the widthwise central portion of the conveying path 1 so that the front and back of the sheet can be aligned during stacking.

Therefore, when the 10,000-yen bill P ₁ is inverted, there is not much problem, but when the smaller-sized bills, that is, the 5,000-yen bill P ₂ , the 1,000-yen bill P _3, etc. are reversed, the length is longer. Although the end faces in the direction are separated from the reference guide portion 1a of the bill transport path 1 and the end faces in the longitudinal direction are not aligned, the aligning means 24 provided corresponding to the stacking chamber 2 automatically causes the bills P ... Arrangement is performed in this direction.

That is, the fixed guide 26 having the alignment reference surface 26a is attached to the side frame 25 located on the reference guide portion 1a side of the transport path 1, and the fixed guide 26 having the alignment reference surface 26a is separated from the side frame 25 and the bill P advances. An arranging lever 27 is provided as a movable arranging member that is swingable in a direction orthogonal to the direction, and strikes an end surface of the bill P to urge it toward the arranging reference surface 26a.

The arranging lever 27 is rotatably supported by a supporting pin 29 protrudingly provided on a fixed plate 28, and is constantly rotated by a coil spring 30 in the clockwise direction in the state shown in FIG. One end face in the direction is attached in the direction of pressing the alignment reference face 26a side.
Further, an extension portion 27a extending into the rotation path of the cam 32 driven by the motor 31 is provided on the pivotal end side of the arranging lever 27, and the arranging lever 27 is moved along with the rotation operation of the cam 32. It is configured to be largely displaced away from the end face of the bill P against the biasing force of the coil spring 30, and is opened to the outside via a link mechanism 34 by the excitation of the solenoid 33 installed on the fixed plate 28. The banknotes P that can be maintained and are separated from the end surface of the banknotes P only when the banknotes P stacked on the separators 11 and 11 are dropped into the stacking chamber 2 and discharged.
When attempting to drop the banknotes P stacked on 11 into the stacking chamber 2, the sorting lever 27 sandwiches a part of the banknotes P into the fixed guide 26 so that the banknotes stacked at the bottom are the separators 11, It prevents the occurrence of misalignment due to breaking without rotating together with 11.

Also, the arranging lever 27 is shown in FIGS.
As shown in the figure, the upper end side corresponding to the separators 11, 11 on which the banknotes P from the impellers 4, 4 are stacked is divided and formed by an elastic piece 271 made of a leaf spring or the like, and stacked on the separators 11, 11. An unreasonable force that tries to act on the moved bills is released by the elastic force, so that the stacking irregularity of the bills P in the separator portion can be prevented.

Reference numeral 35 in the figure is a guide member for guiding the banknotes carried into the stacking chamber 2 so that the banknotes are reliably stacked on the carrier 22, and is in a nested state with the carrier 22.

Then, the banknotes P ... which are sequentially carried out from the transport path 1, that is, the banknotes P ... in which the front and back have been completely aligned are held in the blades 4a, 4a of the impellers 4, 4 and accompany the rotation thereof. 2 will be guided into and integrated on the carrier 22. At this time, that is, the designated number (for example, 100
When the banknotes P ... In (sheet) are transported, the receiving portions 16 of the separators 11 and 11 are at the standby position near the exit of the transport path 1.

When the last banknote P of the designated number of sheets passes the predetermined detection position, the separator 11 is rotated at the same speed in the same direction as the rotation direction of the impellers 4 and 4, and is rotated at the discharge receiving and stacking position in the stacking chamber 2. Stop. Then, the succeeding banknotes P ... After the designated number are temporarily accumulated on the receiving portion 16.

On the other hand, during such a bill stacking operation, the arranging lever 27 of the arranging means 24 strikes the end faces of the banknotes P ... On the carrier 22 and on the receiving portions 16 of the separators 11 and 11 and presses them against the fixed arranging reference face 26a. , The direction orthogonal to the traveling direction, that is, the longitudinal ends of the banknote P are aligned.

In this way, the succeeding banknotes P ... In the banknote group P ...
While being held by Nos. 1 and 11, the carrier 22 is moved to be sent to a sealing device (not shown) or the like which is a post-process. Then, after that, the carrier 22 is returned to the original position, and the temporarily held banknotes P on the separators 11 and 11 are transferred onto the carrier 22 as the separators 11 and 11 rotate. The operation described above is repeated.

Since the arrangement by the arrangement means 24 is prepared in advance in the state of a small number of sheets on the separator 11 which are easy to be arranged, the arrangement on the carrier 22 can be performed more reliably.

Incidentally, in the above-mentioned one embodiment, the drive source of the arranging means 24 is explained by using the dedicated motor 31.
Not limited to this, for example, the rotation of the impellers 4 and 4 may be interlocked via a power transmission system such as a gear mechanism.

In addition, it goes without saying that the present invention can be modified in various ways within the scope of the present invention.

〔The invention's effect〕

As described above, according to the present invention, the aligning member is provided corresponding to the end surface of the paper sheets accumulated in the accumulating portion and the end surface side of the paper sheets accumulated on the separator, and in the accumulating portion and on the separator. Since the end faces of the paper sheets accumulated in the stack are intermittently urged to arrange the paper sheets accumulated in the accumulating section and on the separator at the same time, it is possible to arrange them from the time when the number of sheets on the separator is small. A positioning effect can be obtained. Further, when the paper sheets stacked on the separator are transferred into the stacking unit by retracting the separator from the stacking unit, the aligning member is retracted to a position outside the end surface of the transferred paper sheets. Since this is done, it is possible to prevent the deviation of the paper sheets due to the paper sheets coming into contact with the arranging member.

As a result, the paper sheets can be collected in an orderly manner with one end surface along the conveying direction aligned, and when stacking the stacked paper sheets, they are artificially arranged as in the conventional case. There is no need, and the sealing work can be performed extremely easily, and there is an effect that it is useful when, for example, consistently performing stacking of paper sheets to paper sealing.
