Abstract

PURPOSE:To enable to accumulate bills systematically in a simple structure, by composing a bill accumulating portion with a vaned belt, at the periphery of which plural flexible vanes are furnished, in a bill counting machine or the like. CONSTITUTION:When bills are carried from a pair of carrier belts 11a and 11b in a random timing, their tips are hit by vanes 14 of a rotating vaned belt 13 and they drop to a stop 16a along a support 16a of a tentative pool 16. By repeating this motion, newly carried bills are put into a space between the already accumulated bills 12a and the vaned belt 13, and accumulated systematically in the pool 16. In this case, even through tips of some bills are folded, they are stored in a space 17 between the flexible vanes 14, and their tips neither strike the bill bandle 12a nor disturb to accumulate smoothly. Therefore, bills can be accumulated systematically in a simple structure with an improved reliability.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a stacking mechanism for stacking and storing paper sheets such as banknotes that are separated and conveyed one by one.

(Prior Art) Bill counting in a bill counting machine or automatic teller machine used in a financial institution such as a bank is performed as follows. For example, when banknotes are loaded into the input slot of a device by a bank employee, the banknotes are separated one by one by a banknote separation and feeding mechanism and fed to a counting unit or a banknote validating unit. . The banknotes that have undergone this discrimination are then fed to the banknote stacking section for stacking again, undergo necessary post-processing, and are configured to return the stacked banknotes to a bank employee or the like.

Conventionally, an impeller having a plurality of blades on the outer circumferential surface of a cylinder called a stacking wheel has been used as a banknote stacking section for stacking the above-mentioned banknotes, for example, as described in Japanese Utility Model Publication No. 57-48840. ing.

Figure 2 is a diagram showing a cross section of an accumulation vehicle, and 1 is an accumulation vehicle;
A plurality of blades 3 are provided on the outer periphery of the cylinder 2 at equal pitches. 4 is a belt for conveying banknotes, and 5 is a partial pool portion for accumulating banknotes 6.

Further, the length of the blade 3 is formed to be approximately the same as the length of the banknotes to be handled.

In the above configuration, when the banknotes 6 are conveyed via the belt 4, the banknotes 6 are stored between the blades 30 provided on the outer periphery of the stacking vehicle 1, and are sequentially stacked in the temporary pool section 6. At this time, in order to ensure complete stacking, the rotation timing of the 30 blades of the 10 stacking wheels is synchronized with the separation and conveyance mechanism (not shown), which is a previous process.

(Problem to be Solved by the Invention) However, when the synchronization is out of sync, the conveyed banknotes collide with the blades 3 of the stacking vehicle 10 and are blown out of the stacking vehicle 1 as shown by the broken arrow. Since the intended accumulation could no longer be performed, a mechanism was provided to ensure synchronized interlocking between the separation conveyance section and the accumulation vehicle. In addition, in order to carry out this synchronization t-11 verification, it is necessary to separate and convey the inserted banknotes at the correct timing in the separation and conveyance section, but it is necessary to separate and convey the inserted banknotes at the correct timing, but it is not possible to carry out paper sheets that are in various states of exhaustion, such as circulating banknotes, at once. Separating and conveying banknotes at different timings requires a complicated mechanism, and even if such a mechanism existed, it would not be possible to reliably store and accumulate banknotes between the blades of the accumulator. Therefore, there is a problem in that banknotes that have been conveyed at an untimely timing are thrown out of the stacking vehicle, resulting in a banknote jam.

Furthermore, when feeding the stacked banknote bundles to the next process, it is necessary to provide a conveying means such as rollers and belts separately from the stacking car, which may lead to an increase in the number of parts and a complicated structure.

(Means for Solving the Problems) In consideration of the above-mentioned problems, the present invention uses an elastic body in a paper sheet stacking mechanism that stacks paper sheets that are conveyed one by one. A vane belt having a plurality of vanes is disposed at the end of a conveyance path along the conveyance direction of paper sheets, and the vane belt rotates so that its blades touch at least a part of the surface of the accumulated paper sheets. It is a consideration.

By these means, the present invention achieves the object of providing a paper sheet stacking mechanism that does not require synchronization with the timing of the paper sheet separation and feeding section, has a simple structure, and can be miniaturized. be.

(Function) Since the present invention is constructed as described above, the plurality of blades that are integral with the impeller rotate and strike one end of the surface of paper sheets, such as banknotes, when they are conveyed. It guides and holds the banknotes to the stacking section for the next process, and by repeating this operation for the transported banknotes, the banknotes are neatly stacked in the stacking section.

(Embodiment) FIG. 1 is a perspective view of the main parts of an embodiment of the paper sheet stacking mechanism according to the present invention, in which reference numerals 11a and 11b denote a pair of conveyor belts connected to a bill separating and conveying mechanism (not shown). So, 1
The paper money 12 separated one by one is held and conveyed. This conveyor belt pair 11a.

In this embodiment, three sets of banknotes 11b are arranged in consideration of holding a rectangular banknote over a wide range in the longitudinal direction. 13 is a blade belt having a plurality of blades 14 (10 blades in this embodiment) on its outer periphery, and is stretched between pulleys 15a and 15b, and is integrally molded from an elastic material such as urethane rubber. ing. In this embodiment, the blade belts 13 are the three conveyor belt pairs 11a.

Two sets of banknotes 12 are placed at positions where they are sandwiched between the belts 11b, and the banknotes 12 conveyed by the pair of conveyor belts 11a and 11b are accumulated in a partial pool portion to be described later.

Reference numeral 16 denotes a partial pool portion that includes a stop portion 16a that abuts and stops the tip of the banknote 12 being conveyed, and a support portion 16b that clamps the stopped banknote 12 between it and the feather belt 13. Moreover, the stop part 16a of the temporary pool part 16 has a notch so as to scoop up the transported banknotes 12, and enters into the space between the two sets of feather belts 130 in a comb shape to be fixed and held. .

FIG. 3 is a cross-sectional view of the mechanism described above, and as is clear from the figure, the blade belt 13 is connected to the conveyor belt pair 11.
a, llb, in other words, the center is shifted to the right with respect to the bill conveyance surface. That is,
Part of the blade belt 13 on the side of the pool portion 16 on the belt outer peripheral surface 1
3a is arranged at a position that substantially coincides with the banknote conveying surface,
In addition, at - time, the support portion 16b of the pool portion 15 has a thickness corresponding to the number of banknotes to be stored, which is predicted in advance.
are placed at a distance equal to the expected amount of distortion. With this arrangement, the blade belt 13 rotates so that its blades 14 come into contact with at least a portion of the surface of the banknotes 12a temporarily accumulated in the boule portion 16.

Further, the rotation speed of the belt outer peripheral surface 13a in the direction indicated by the arrow a is controlled by a control means (not shown) of the feather belt 13.
The rotation is controlled to almost match the paper sheet conveying speed in the direction, and the rotation is stopped when the stacking operation of a predetermined number of sheets is completed. Below, the operation of the paper sheet stacking mechanism with the above-mentioned configuration will be explained. do.

In FIGS. 1 and 3, conveyor belt pairs 11a, 1
When the banknote 12 is conveyed at an arbitrary timing after 1bf, the tip of the banknote 12 is hit by the blade 14 of the blade belt 13 which is rotating by a control means (not shown), and the banknote 12 is struck by the support part of the temporary pool part 16. It falls along the side 16b until it stops at the stop 16a. Thereafter, the above operation will be repeated for the banknotes 12 that are being conveyed.
The newly conveyed banknotes are placed in the banknote bundle 12 that has already been stacked.
& and the blade belt 130 and are accumulated, and are neatly accumulated in the temporary pool section 16.

During this stacking operation, as the number of stacked banknotes increases, the blades 14 of the feather belt 13 move the stacked banknote bundle 12g.
This increases the contact area with the surface and moves in the direction of the arrow.

Here, if the leading edge of the banknote 12 being conveyed is bent, there is a concern that the leading edge will collide with or receive high resistance from the banknote bundle 12& that has already been stacked, making it impossible to stack the banknotes in an orderly manner. To explain this point, as is clear from FIG.
will be bent when the banknotes 12 are conveyed sequentially, and at that time a space 17 is formed. That is, this space 17 is a space that can accommodate the tips of the banknotes 12 that are sequentially conveyed, and even if the tips are bent, there is enough room to accommodate them as they are, and the above-mentioned concerns can therefore be resolved. be.

Next, using FIG. 4, a comparison will be made between the stacking mechanism according to the present invention and the conventional mechanism using stacking cars shown in FIG. 2, and their operation, size, etc. will be discussed.

First, in the collecting vehicle shown in FIG. 2, since the blades are formed on the outer periphery of the cylinder as described above, the outer diameter thereof is inevitably large. Furthermore, this means that it is not possible to construct a structure in which components that regulate the banknotes, such as conveyance paths and guides, are placed close to the trajectory drawn by the trailing edge of the banknotes shown in A, and there is a long space in which the banknotes are not held between the time when the banknotes are discharged and the banknotes are stacked. It is causing a cause.

That is, if the free space t of banknotes becomes longer, for example, banknotes that are transported out of synchronization will be repelled by the blades of the impeller and ejected to the outside as shown by arrow B, which may cause equipment failure. & Inviting [Second seven days.

On the other hand, in the present invention, the outer diameter D' and the space t' are
It is clear from the explanation using FIGS. 1 and 3 that it can be set much smaller than that shown in the figure, and that the overall size of the stacking mechanism can also be configured to be smaller. In other words, since a mechanism for regulating the freedom of banknotes can be constructed using a feather belt, a support part of the temporary pool, etc. very close to the banknote discharge port, the space t' in which the banknotes are free becomes extremely small. .

In addition, in FIGS. 1 and 3 showing the embodiment of the present invention, the blades of the blade belt are made so that they do not overlap each other, but it is possible to increase the length of each blade so that the blades overlap each other. In this case, the banknotes are held between the blades and a portion of the banknotes are sent to the ghoul section, and the same effect is obtained.

Further, as the blades of the impeller in the above embodiment, the blades may have a small coefficient of friction on the side that contacts the accumulated paper sheets, and a large coefficient of friction on the opposite side. In this case, no large feeding force is applied to the already stacked paper sheets, so the stacked paper sheets are not bent or damaged, and the driving force of the blade belt is also small. It will be done.

Furthermore, the large frictional force makes it possible to reliably cause some of the newly fed paper sheets to accumulate in the pool, and this effect becomes more pronounced when the blades are made longer.

FIG. 5 is a sectional view showing an application example of the paper sheet stacking mechanism according to the present invention, and shows an example in which the paper sheets temporarily stacked in FIGS. 1 and 3 are connected to a mechanism for separating and conveying them. . below,
explain.

When the accumulation operation is completed according to the procedure explained in FIGS. 1 and 3, the temporary pool section 16 moves in the direction of arrow C, and the temporary pool section 16 moves to the position of the partial pool section 16-1 indicated by the broken line, that is, the accumulation operation is completed according to the procedure explained in FIGS. The tip of the banknote is stopped at a position facing the suction drum 18. At this time, the blade belt 13 partially moves in the direction indicated by the arrow at approximately the same speed as the moving speed of the pool portion 16. After this,
A part of the banknote pushing plate 19 passes through a not-shown through hole in the support part 16b of the pool part 16 and draws the accumulated banknotes to the suction drum 18.
to press. As a result, the suction drum 18 sucks the banknotes and rotates in the direction of the arrow d to separate and convey the banknotes t'' one by one.In other words, in this example, the structure of the present invention is effectively utilized.

To be more specific, when feeding the stacked banknotes to the next step, the separation conveyance mechanism, the temporary pool section 16 is moved in the direction of arrow C, and the feather belt 13 is also moved, thereby causing the feather belt to function as a conveying means. This is what I did. Therefore, no new conveyance means such as rollers or belts are required and a simple structure can be achieved.

(Effects of the Invention) As described above in detail, according to the present invention, the banknote accumulating section is constructed using a vane belt truck having a plurality of vane-like elastic bodies on the outer periphery, so that it is possible to use a banknote accumulating section using a vane belt truck having a plurality of vane-like elastic bodies on the outer periphery. It has a simpler structure and is smaller than a stacking mechanism using a banknote, and can stack banknotes in an orderly manner without any particular synchronization timing. or,
Since the feather belt is obtained by integrally molding an elastic body such as a dem, it is inexpensive, and since the feather belt itself can be used as a conveyance means, it is also possible to simplify the conveyance mechanism after banknotes are stacked. Therefore, many excellent effects can be expected, such as improved reliability of the mechanism's operation and easier maintenance and inspection.
