Abstract

PURPOSE:To have stacking of sheets in the aligned condition in which their edges facing aside the transport direction are put in a plane by furnishing a side edge aligning means for the sheets to be stacked in a stacking chamber. CONSTITUTION:When bank notes are to be stacked, a lever 27 of an aligning means 24 beats the end face of each bank note P on a carrier and on the receptacle part 16 of separators 11, 11 so as to press them to a fixed reference surface for alignment. Thus the side edges of the bank notes are put in plane, i.e. they are put in alignment in the respect of sides across the transport direction. A certain number bank notes P thus aligned on the above-mentioned carrier 22 are sent thereby to a packing device as subsequent stage while the following bank notes P are held by the separators 11, 11. Then the carrier 22 returns to its original position to receive said following bank notes temporarily held on the separators 11, 11 in the course of rotation of them. This procedure is repeated to ensure that all bank notes fed are stacked neatly.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] 'The present invention involves receiving and holding paper sheets, such as banknotes, which are sequentially carried out from a conveyance path, between the blades of a rotating impeller.
This invention relates to an improvement in a stacking device for good paper sheets, which allows the discharged sheets to be stacked one after another in a stacking chamber.

[Technical background of the invention and its problems]

For example, in a banknote sorting machine, banknotes supplied in bulk are taken out one by one, distinguished, and separated into reusable banknotes (good banknotes) and reusable banknotes (damaged banknotes). Each sheet is stored in a predetermined number of sheets, for example, 100 sheets.

Recently, in this type of device, a stacking device is being developed that automatically stacks banknotes with their front and back sides aligned and facilitates the post-processing step of wrapping.

In this type of device, - 10,000 yen note P1% 5000 yen note Psu,
We handle banknotes P... of different sizes, such as 1,000 yen note P3,
Moreover, in order to increase the processing capacity, it is necessary to convey the banknotes at a short conveyance pitch, so the banknote conveyance path 1 is normally used for the largest size banknotes among the handled banknotes, i.e. -10,000 yen note Pl, as shown in FIG. The size width W is set to be slightly larger than the longitudinal dimension, and the banknotes P are taken out and conveyed in the lateral direction with one end surface in the longitudinal direction as a reference.

Then, the banknotes P...(
Figure 5 shows the case of 5,000 yen red P2).
The sheets are reversed 180 degrees around the center in the width direction to align the front and back sides during stacking.

However, with such a configuration, there is no problem if the largest size banknote, i.e. -10,000 yen note P, is reversed, but when the banknote is υ smaller than this, i.e., 5,000 yen note P2, When a 1,000 yen note P3 or the like is reversed, it is reversed around a position shifted from the longitudinal center of the banknote P, so that the end face in the longitudinal direction is separated from the reference guide part 1& of the banknote transport path l. As a result, the longitudinal direction of the banknotes becomes uneven, and the stacking condition becomes disordered. If this continues, it will not be possible to seal the banknotes P2... with the band 3 in a state shown in FIG. This was a major hindrance to getting people to do it.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and its purpose is to provide paper sheets with one end surface aligned in a direction perpendicular to the conveyance direction, while having a relatively simple structure. It is an object of the present invention to provide a paper sheet stacking device that can stack paper sheets in an orderly manner.

[Summary of the Invention] In order to achieve the above object, the present invention receives and holds paper sheets sequentially carried out from a conveyance path between the blades of an impeller, and sequentially discharges them into a collection chamber as they rotate. A rotary separator is provided in such a manner that it can be stacked and rotated at the same speed in the same direction as the rotation direction of the impeller, so that subsequent paper sheets after the designated number guided by the impeller are stacked in the stacking chamber. In a stacking device for paper sheets that is temporarily stacked on a receiving part, an arrangement means is provided for arranging the filter paper sheets stacked in the stacking chamber in a direction perpendicular to the direction of travel of the filter paper sheets,
The structure is such that the paper sheets stacked in the stacking chamber can be stacked in an orderly manner while removing any misalignment of the end faces in the direction along the conveyance direction.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 19 to 4. In the figure, 1 is a banknote conveyance path for conveying banknotes P as paper sheets, '>D, ', ' are blades 4 &, which receive and hold banknotes P sequentially carried out from this conveyance path 1 during 4h.
This is an impeller that sequentially discharges and accumulates sheets in the collecting chamber M 2 by rotating in the 2 directions of the f chamber. These impellers 4.4 are connected to a retaining wheel portion 7 which is rotatably supported on the outside of the four rotor rotating shaft 5 via a bearing 6.6 as shown in FIG. A large number of blades 4a protruding radially from the outer periphery and spirally curved in the direction of rotation, a gear 8 provided on the coupling wheel portion 2, and a gear 9 rotationally driven by the electric motor 10. Due to the meshing, it is rotated at a constant speed in the direction of the arrow in Fig. 2.

Reference numeral 11.11 denotes a pair of left and right separators arranged on the left and right sides of the impeller 4.4 as shown in FIG. A cam retaining portion 1 consisting of a freely rotatable roller trochanter is attached to a lever portion 14 which is pivotally mounted and has nine rotational fulcrums and extends in a direction perpendicular to the separator rotating shaft 5.
5, and a receiving part 16 for dividing the specified number of sheets, which is located inward from the rotary outline of the blades of the impeller 4.4 in the separator standby position and extends in the protruding direction of the blades 4m+1m. The senoforator 11, 11, which consists of a rotating lever, has one end fixed to the separator support 12. It is urged in the direction of engagement with the notch 5a of the separator rotating shaft 5 by a spring force (not shown).

The center and blade receiving portions 16 are curved to have substantially the same shape as the blades 4a*4a of the impeller 4.4.

Further, the rotating shaft 5 of the separator 11.11 is constituted by a hollow shaft as shown in FIG. 1 on which the impellers 4, 4 are rotatably supported, and the impeller drive unit (shaft) is inserted into and supported within this hollow shaft. It is connected via a clutch mechanism 21 to a drive shaft 20 which rotates by receiving a shearing force from the meshing gears 18, 19) on the end side. This 7-latch machine #21 uses a two-position spring clutch that can stop separators ii and i in two positions: a standby position and a discharged paper receiving and collecting position.

Further, the bottom of #recording chamber 2 is constituted by an accumulation moving carrier 22 as a member, which is displaced by a carrier transfer means (not shown), and transfers the specified number of accumulated banknotes P... to the next process. It is designed to be transported. This carrier 22 has a horizontal receiving portion 23h and a stacked banknote group P...
It is composed of a plurality of L-shaped members 23... each having a support portion 23b that backs up one end surface in the lateral direction of the L-shaped member 23, and is nested with the impellers 4, 4 and the center and armrests 11 and 11. . Then, the banknotes P guided into the accumulation chamber 2
By bringing one end surface in the transverse direction into contact with this support portion 23b, the sheets are stacked in a state in which they are aligned in this direction.

On the other hand, as described above with reference to FIG.
The dimensional width W is set to be slightly larger than the longitudinal dimension of PIO, and the banknotes P are taken out and conveyed from one end surface in the longitudinal direction in the lateral direction with reference to the reference guide part 11.

Then, the banknotes P... (
Fig. 5 shows the case of 5,000 yen coins P2] is reversed 180 degrees around the center in the width direction of the conveyance path 10 to arrange the front and back sides when stacking.

For this reason, there is not much of a problem when reversing a -10,000 yen note p, but when reversing a much smaller banknote, such as a 5,000 yen note p2 or a 1,000 yen red note P3, the longitudinal direction Although the end faces of the banknotes P are separated from the reference I-id portion 1m of the banknote transport path 1, and the longitudinal end faces become uneven, the banknotes P ...is being arranged in this direction.

That is, a fixed side frame 25 located on the reference guide portion la side of the conveyance path l is attached with a fixed side frame 26 having a collection reference surface 26h, and is spaced apart from this collection reference surface 26&, and the banknote P is A collection lever 27 is provided as a movable collection member that is swingable in a direction perpendicular to the direction of travel, and strikes the end face of the banknote P. ;1
．． It is designed to bias toward the alignment reference surface 26h.

This collection lever 27 is rotatably supported via a support pin 29 protruding from a fixed plate z8, and is always rotated clockwise in the state shown in FIG. It is attached in a direction in which one end surface is aligned and pressed toward the reference surface 26&.

Further, an extending portion 271L is provided on the pivot end side of the stocking lever 27, and extends into the rotation path of the cam 32 driven by the motor 31K. It is configured to be largely displaced away from the end face of the banknote P against the biasing force of the spring 30, and can be maintained open to the outside via the link mechanism 34 by excitation of the solenoid 33 installed on the fixed plate 28. Nishi, Se, Paleta 11.
Only when the banknotes P accumulated in llK are dropped and discharged into the accumulation chamber 2, the banknotes P are separated from the end face of the banknotes P, thereby removing the banknotes P accumulated on the separator l1*11 into the accumulation chamber 2.
When attempting to drop the banknotes P, the collection lever 27 pinches a part of the banknotes P against the fixed guide 26, and the banknotes stacked at the lowest position do not rotate together with the separators 1 and 1 and break. This prevents irregularities from occurring.

Furthermore, the above-mentioned collection lever 27 is shown in FIGS.
As shown in the figure, the upper end side corresponding to the separator 11.11 where the banknotes P from the impeller 4.4 are accumulated is divided by an elastic piece 271 made of a plate spring or the like, and the banknotes P from the impeller 4.4 are accumulated on the separator 11.11. The elastic force allows the unreasonable force exerted against the movement of the banknotes to be released, thereby preventing the banknotes P from being stacked unevenly in the separator portion.

Note that 35 in the figure is a guide member that guides the banknotes carried into the stacking chamber 2 so that they are reliably stacked on the carrier 22, and is nested with the carrier 22.

Thus, the banknotes P are sequentially carried out from the conveyance path 1...
In other words, the banknotes P, whose front and back sides have been completely arranged, are held in the blades 4m and 4a of the impeller 4.4, guided into the accumulation chamber 2 as they rotate, and accumulated on the carrier 22. It turns out.

At this time, that is, when a specified number of banknotes P (for example, 100) are being transported, the receiving portion 16 of the security rack 11 is at a standby position near the exit of the transport path 1.

When the last specified number of banknotes P passes a predetermined detection position, the separator 1 is rotated at the same speed in the same direction as the rotation direction of the impeller 4. Rotation stops. Then, subsequent banknotes P after the specified number are temporarily accumulated on the receiving section 16.

On the other hand, during such banknote stacking operation, the collection lever 27 of the collection means 24 is moved on the carrier 22 and on the item 4.
The ends of the banknotes P... on the receiving portion 16 of the tray 11.11 are struck and pressed against the fixed collection reference surface 261, and the banknotes P are collected in a direction perpendicular to the direction of movement, that is, both longitudinal ends of the banknotes P. .

In this way, the predetermined number of banknotes P... on the carrier 22, which have been assembled, are transferred to the post-process by the movement of the carrier 22 while the subsequent banknotes P... are held by the separators 11, 11. It is fed into a sealing device (not shown) or the like. After this, the carrier 22 returns to its original position, and the temporarily held Nanano 4 Lator 11
11 is transferred onto this carrier 22 as the security rackers 11, 11 rotate, and the above-described operation is repeated.

In addition, the stocking by the stocking means 24 is carried out by the stocker 11.
Since the sheets are arranged in advance in a small number that is easy to arrange on the carrier 22, the arrangement on the carrier 22 can be carried out more reliably.

Incidentally, in the above-mentioned embodiment, a case was explained in which a dedicated motor 31 was used as the drive source of the arrangement means 24.
The present invention is not limited to this, and for example, the rotation of the impeller 4.4 may be linked 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 without departing from the gist of the invention.

〔Effect of the invention〕

As explained above, according to the present invention, an arrangement means is provided for arranging the filter paper sheets accumulated in the accumulation chamber in a direction perpendicular to the traveling direction thereof, and Since the configuration is such that the end faces in the direction are aligned, it is possible to stack paper sheets in an orderly manner with one end face along the conveyance direction aligned, although it is a relatively simple configuration, and the stacked paper # When sealing type L, there is no need to manually arrange the items as in the past, making the sealing process extremely easy, and is useful when performing the entire process from stacking paper sheets to sealing them. It has the effect of
