Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet stacking apparatus mounted on a paper sheet processing apparatus for processing paper sheets such as securities, and more particularly to a paper sheet stacking apparatus having an end surface of paper sheets and a mechanism. .

  A paper sheet processing apparatus for processing paper sheets such as securities takes out the paper sheets one by one from the bundle of paper sheets input in a batch according to the processing unit, and conveys them one by one. The paper classifier is discriminated by a class discriminating device, and a normal ticket (a reusable genuine note is called a genuine note), a non-reusable ticket (a non-reusable genuine note is called a non-revenue note), and a fake They are classified as indeterminate tickets such as badly transported tickets.

  The correct bills or the damaged bills sorted in this way are transported to the stacking device and bundled with a paper strip every 100 sheets to form a bundle H.

  In the stacking apparatus, a method for stacking the transported paper sheets without damaging the transported paper sheets while absorbing the transport energy of the transported paper sheets at a delivery portion with the stacker for stacking the transported paper sheets. An accumulation device using an impeller is used.

  In this stacking device, a plurality of blades are arranged around the rotation shaft, and the paper sheets are taken in between the blades. The taken paper sheets are rotated with the rotation of the impeller to absorb the kinetic energy, scraped out by the paper sheet scraping plate, and accumulated in the stacker (for example, see Patent Document 1). ).

  At the time of stacking in the stacker, the rear end of the paper sheet in the transport direction is prepared by an end face arranging device.

  Hereinafter, an end face assembling mechanism relating to a conventional stacking apparatus will be described with reference to FIGS. The end face arranging device 730 includes a diaphragm 730a, an eccentric cam 730c that transmits vibration to the diaphragm 730a, a vibration motor (not shown) that rotationally drives the eccentric cam, and the vibration motor that moves in parallel to the left and right. A link mechanism (not shown) and a sensor (not shown) for detecting this parallel movement are included.

The diaphragm 730a is arranged so as to be rotatable about a fulcrum 730b, and the paper sheets P are arranged by giving vibration to the rear end thereof when the paper sheets P are dropped.
JP 2006-213506 A (Page 5, FIG. 2)

  However, in the illustrated integrated device, two problems have been pointed out.

  The first problem is that when the length of the paper sheet P in the conveyance direction (hereinafter referred to as the length) changes, the sorting performance of the paper sheet P may be poor. The reason is that the diaphragm 730a has a structure corresponding to the length of the paper sheet P by rotating around the fulcrum. Further, the deflection angle of the diaphragm 730a is set to be symmetrical with respect to the center of the entire stroke. Therefore, for paper sheets P having a long length, they are arranged by the diaphragm 730a in the middle of dropping, and are collected in the stacker. In some cases, the sorting function by the diaphragm 730a may not work in the middle, and the accumulated paper sheet P may be bent, or the right end of the paper sheet P may ride on the diaphragm 730a. (See FIG. 9).

  The second problem is that the length variation of the paper sheet P itself cannot be absorbed. That is, when all the lengths of the paper sheets P are unified, the accumulation is good, but the length of the paper sheets P varies in the range of the dimensional tolerance. At this time, as shown in FIG. 9, when matched to the paper sheet P having the maximum tolerance, the diaphragm 730 a cannot contact the paper sheet P smaller than that, and the arrangement becomes poor. On the other hand, as shown in FIG. 10, when matched to the paper sheet P having the minimum tolerance, the vibration plate 730 a comes into contact with any paper sheet, but the paper sheet P having the maximum tolerance is deflected. As a result, there is a problem that the range becomes worse. In particular, it is an important issue when it is required that the finished product is stable, such as a new ticket in which the paper sheet P is a new paper sheet.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an accumulator that improves the sorting performance of the accumulator regardless of the length of paper sheets to be processed.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a paper sheet processing apparatus 100 equipped with a stacking apparatus according to a first embodiment of the present invention. The paper sheet processing apparatus 100 determines whether the paper sheet P such as securities is genuine (true or fake) or correct (whether it can be recirculated or non-recyclable). The correct bills are collected by the accumulating device 70, and the lost tickets are accumulated by the accumulating device 80. The paper sheet processing apparatus 100 is provided with a supply unit (not shown) that collectively feeds the stacked paper sheets P. The paper sheets P stacked on the supply unit are taken out one by one at regular intervals by the take-out device 4 and supplied to the transport path 5. The transport path 5 is composed of a transport roller (not shown) and a transport belt (not shown), and transports the paper sheet P from the upstream in the transport direction as indicated by the arrow A1 in the transport direction to the downstream in the transport direction.

  The paper sheet P conveyed in this way is discriminated by a paper sheet discriminating device (paper sheet discriminating means) 6. The paper sheet discriminating device 6 detects and discriminates the physical characteristics of the paper sheet P, and is composed of a plurality of devices, and is provided in the transport path 5 toward the downstream in the transport direction.

  As a result of the discrimination by the paper sheet discriminating device 6, the correct bill is conveyed to the stacking device 70, and the damaged bill is transported to the stacking device 80. Since the integrated device 70 and the integrated device 80 are configured in the same manner, the integrated device 70 will be described below.

  The paper sheet P determined to be a genuine note is conveyed to the stacking device 70 side by the sorting gate 51. A stacking device 70 using an impeller is disposed at the end of the transport path, and the paper sheets P are taken in by the stacking device 70. When the taken paper sheets P are counted and reach 100 sheets, they are transferred to a sealing device 75 disposed at the lower portion and bound by a paper strip by the sealing device 75 (hereinafter referred to as sealing). ). In this way, the small bundle H is formed. The formed small bundle H is changed in direction by the small bundle discharge device 76 and transferred to the small bundle conveying device 9.

  The small bundle conveying device 9 receives the small bundle H discharged from the small bundle discharging device 76 and conveys it to the post-processing device 10 side.

  In the post-processing device 10, 10 bundles of the bundles H discharged from the bundle discharge device 76 are stacked and further bundled (bundled together), and attributes such as the type of the sheet P are printed on the bundled band. Since it is out of the scope of the gist of the invention, detailed description is omitted.

  FIG. 2 is a block diagram of the integrated device 70 shown in FIG. FIG. 3 is a perspective view of the stacking device 70 shown in FIG. Hereinafter, the configuration and operation of the integrated device 70 according to the present invention will be described with reference to FIGS.

  The stacking device 70 includes a rotating impeller 71, an end face arranging device 73, a paper sheet scraping plate (scraping means) 72, and the like.

  The impeller 71 is configured by incorporating a plurality of blades 71a around the rotation shaft 71b. The impeller 71 takes in the paper sheet P conveyed in the direction indicated by the arrow B between the blades 71a and 71a and absorbs the transport energy of the paper sheet P while rotating, thereby damaging the paper sheet P. Can be taken in without giving.

  The end face arranging device 73 includes a diaphragm 73a and a diaphragm driving device 74 that applies vibration to the diaphragm 73a.

  The diaphragm 73a is composed of a plate-like body that surrounds the outer periphery of the impeller 71, the upper part is pivotally supported by a fulcrum (rotating shaft) 73b, and a drive for transmitting a driving force to the diaphragm 73a at a substantially central part. A force transmission part 73c is provided.

  The vibration plate 73a configured as described above prevents the paper sheets P taken into the impeller 71 from jumping out from the stacking box 70a, and the paper sheets scraped from the paper sheet scraping plate 72. It has a function of arranging the end faces of the paper sheets P while applying vibration to the rear end of P.

  The paper sheet scraping plate 72 is configured in a plate state that is inclined toward the center of the impeller 71 and upstream in the transport direction, and the paper sheet P scraped to the paper sheet scraping plate 72. Are accumulated in the accumulation box 70a.

  In the stacking device 70 configured as described above, the main part of the present invention is a part related to the end face arranging device 73, and will be described in detail below.

  The driving force transmitting portion 73c is provided with an elliptical donut-shaped hole, and the rotating roller 74a of the diaphragm driving device 74 is disposed in the hole.

  The rotating shaft of the rotating roller 74a is connected to an eccentric cam 74b whose center axis is shifted, and the rotating shaft of the eccentric cam 74b is connected to a vibration motor 74c.

  When the vibration motor 74c rotates in this state, the rotation shaft of the rotation roller 74a rotates while fluctuating by a predetermined amount in the horizontal direction. This fluctuation is transmitted to the driving force transmitting portion 73c, and the diaphragm 73a configured integrally with the driving force transmitting portion 73c vibrates.

  Further, a drive motor 74g that moves the vibration motor 74c in parallel from side to side, a link mechanism 74e that transmits the driving force of the drive motor, a sensor 74f that detects the parallel movement, and the like are arranged.

  The diaphragm 73a is disposed so as to be rotatable about the fulcrum 73b. Since the arrangement position of the end face arranging portion 73p of the diaphragm is set according to the length of the paper sheet P to be processed, it is rotated accordingly (details will be described later).

  The eccentric cam applies vibration to the diaphragm 73a as the rotation shaft moves up and down and left and right.

  FIG. 4 is a diagram illustrating an arrangement position of the diaphragm 73a when the length L in the transport direction varies depending on the type (ticket type) of the paper sheet P to be handled. In the figure, when the length L of the paper sheet P changes from L1 to L3, the arrangement position of the end face arranging portion 73p of the diaphragm 73a is changed from P1 to P3 as follows. FIG. 5 is a diagram showing an angle θ between the end face arranging portion 73p and the end face of the paper sheet P when the length L of the paper sheet P changes from L1 to L3.

P1: Arrangement position of the end face arranging portion 73p in the case of the length L1 of the paper sheet P (see FIG. 5 (1))
P2: Arrangement position of the end face arranging portion 73p in the case of the length L2 of the paper sheet P (see FIG. 5 (2))
P3: Arrangement position of the end face arranging portion 73p in the case of the length L3 of the paper sheet P (see FIG. 5 (3))
As described above, since the arrangement position of the end face arranging portion 73p of the diaphragm 73a differs depending on the type of the paper sheet P to be handled, the fulcrum that pivotally supports the diaphragm 73a rotates correspondingly.

  In this case, the end face arranging portion 73p of the diaphragm 73a of the present invention is arranged to be parallel to the rear end face of the short paper sheet P to be handled. Further, the end face arranging portion 73p of the diaphragm 73a is configured so as to have such a structure (see FIG. 5 (1)).

  Accordingly, as the length of the paper sheet P becomes longer, the angle θ between the end face arranging portion 73p and the end face of the paper sheet is arranged to open counterclockwise. That is, in order to collect the accumulated paper sheets P, it is desirable to accumulate the accumulated paper sheets P so as to abut against the paper sheet scraping plate 72. As the sheets are accumulated, the paper sheets P accumulated in the height direction are pressed counterclockwise, so that the leading ends of the paper sheets P are pressed toward the paper sheet scraping plate 72 side and arranged. .

  In order to arrange the end face arranging portion 73p so as to be parallel to the rear end face of the paper sheet P regardless of the length of the paper sheet P, it is necessary to move the fulcrum 73b of the diaphragm 73 in parallel in the length direction. is there. For this parallel movement, a translation mechanism, a space, and a control device are required. In order to simplify these and obtain the same effect, the method of the embodiment described above is effective.

  FIG. 6 shows a diaphragm 73 used in the stacking apparatus 70 according to the second embodiment of the present invention. FIG. 7 is a diagram for explaining the effect of the second embodiment shown in FIG. Since parts other than the diaphragm 73 are the same as those in the first embodiment, the description thereof is omitted. The diaphragm 73 is used in the stacking apparatus 70, but the diaphragm used in the stacking apparatus 82 is also configured in the same manner, so that the description thereof is omitted.

  In the second embodiment, a backlash Δx is provided between the drive transmission unit 73c and the rotation roller 74a. This play is intended to absorb the tolerance when the length of the paper sheet P has a certain tolerance. That is, in order to solve the problem that if the position of the end face arranging portion 73p of the vibration plate 73 is matched with the paper sheet P having the maximum tolerance, the vibration plate 73 cannot contact the paper sheet P shorter than that and the assortment becomes poor. In this embodiment, when the diaphragm 73 is aligned with the minimum tolerance paper sheet P, and the long paper sheets P are accumulated within the tolerance range, the diaphragm 73 can be retracted by an amount equivalent to the tolerance Δx. FIG. 7 is a diagram illustrating the effect of this embodiment. The illustrated example shows a state in which the diaphragm 73 is retracted because the long sheet P1 is accumulated on the sheet P having the minimum tolerance and the position of the diaphragm 73 aligned.

  According to the embodiment of the present invention, it is possible to contact the rear end of the paper sheet P on which the diaphragm 73 is accumulated even when the length of the paper sheet in the conveying direction varies within a tolerance range. , Can be stocked.

(Modification)
As a modification of the present embodiment, the same effect can be obtained even if the roller surface of the rotating roller 74a is made of an elastic deformation material instead of providing the play X. In the present embodiment, the same effect can be obtained even when urethane rubber is used as the elastic deformation material.
