Description

  The present invention relates to an antistatic mechanism and a paper sheet medium processing apparatus for preventing charging of a paper sheet medium conveyed on a conveyance path.

  Examples of paper sheet processing apparatuses that handle paper sheet media such as banknotes and slip sheets include automatic transaction machines (ATM: Automated Teller Machine) equipped with a BRM (Bill Recycle Module), ticket issuing terminals, and communication printers. The automatic transaction apparatus is an apparatus for depositing and withdrawing banknotes installed in various places such as a bank, a station premises, and a convenience store. The ticket issuing terminal is an apparatus for issuing a ticket installed in a station premises or the like.

  In such a sheet medium processing apparatus, the outside of the unit is surrounded by a housing sheet metal or the like in order to maintain the strength of the apparatus, but the conveyance path for conveying the sheet medium provided inside the unit is Due to the price and weight constraints of the device, it is often made of molded products. Since the conveyance path made of a molded product is electrically resistive, static electricity is generated due to friction between the conveyed paper sheet medium and the conveyance path, thereby charging the sheet medium.

  When a plurality of sheet media charged by friction with the transport path are stored in the stacker unit, the sheet media are stuck and separated by static electricity when separated from the stacker unit in which the sheet media are stored. Since the second sheet medium is taken out to the first sheet medium, it causes a separation failure of the sheet medium device. In addition, since the charged paper sheet media stick to each other when stacked on the stacker unit, it causes a stacking failure of the paper sheet medium device. Further, the charged paper sheet medium sticks to the molded product when the customer takes out the paper sheet medium from the customer service section, which causes a defective takeout of the paper sheet medium device.

  On the other hand, for example, Patent Document 1 discloses a technique for discharging static electricity charged in a paper sheet medium in the air by providing a recess in a molded product of a conveyance path and providing a conductive film on the surface of the recess. Yes.

  Further, for example, Patent Document 2 discloses a technique for eliminating static electricity by providing a discharge needle in a stacker unit that stores a paper sheet medium so as to self-discharge a charged charge on the stacked paper sheet medium. .

  Further, for example, in Patent Document 3 and Patent Document 4, a static elimination brush is provided on a metal portion of a conveyance path, and the static electricity charged on the paper sheet medium is applied to the metal portion by bringing the conveyed paper sheet medium and the static elimination brush into contact with each other. A technique for discharging is disclosed.

  However, the technique disclosed in Patent Document 1 gradually eliminates static electricity charged on a paper sheet medium by air discharge, but does not actively discharge metal parts having high conductivity. For this reason, in an apparatus that transports a large amount of paper sheet media such as an automatic transaction apparatus at high speed, the discharge speed cannot be followed because the discharge speed is slower than the transport speed, and the paper sheet medium cannot be sufficiently discharged.

  Further, in the technique disclosed in Patent Document 2, since the charge is eliminated only at the start point and the final point of the conveyance path, the charge is not eliminated on the conveyance path, and sufficient discharge cannot be performed.

  Furthermore, in the techniques disclosed in Patent Document 3 and Patent Document 4, since the neutralizing brush that is not originally required for conveyance is brought into contact with the paper sheet medium being conveyed, the conveyance behavior is affected by the load on the paper sheet medium. give.

  In addition to the paper sheet medium, it is conceivable that static electricity is charged in the molded product in the conveyance path. In this case, the charged static electricity is gradually discharged from the molded product by air discharge. However, when the amount of charged static electricity is large, a screw or a metal part mounted near the charging part due to apparatus vibration or the like approaches the charging part, and discharge to the screw or the metal part occurs. Due to this discharge, electrostatic noise is applied to the electric signal from the sensor cable or the connector, and a device failure occurs. Furthermore, when a discharge from a charged part to a metal part or the like occurs with a large amount of charged electric charge, the amount of discharge increases and the FG (Frame Ground) is shaken, which causes a communication failure to a communication line such as a USB. Occur.

  Since most of the conveyance paths use molded products because of the amount of metal used and the weight when requesting equipment design, it is difficult to use other than molded products. For this reason, as a method for preventing static charge of the molded product, a method of connecting the molded product and the metal part of the housing with a sheet metal, a plate spring, an FG wire, a conductive mold, or the like is conceivable. However, even if the molded product and the metal part are connected, the electrical resistance of the molded product is large and the discharge time becomes long. A sufficient discharge effect cannot be expected.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to discharge the electric charge charged in the paper sheet medium at high speed and sufficiently without affecting the transport behavior. It is an object of the present invention to provide a new and improved antistatic mechanism and paper sheet medium processing apparatus capable of being used.

[1-3. Antistatic mechanism]
Next, this embodiment and the antistatic mechanism of the automatic transaction apparatus 1 according to this embodiment will be described. First, in describing the antistatic mechanism, the blade mechanism 18 provided with the conventional antistatic mechanism will be described in detail.

  As described with reference to FIG. 1, each transport path is switched by the rotation of the blade 180. FIG. 3 is an explanatory diagram showing the switching of the conveyance path using the conventional blade mechanism 18. The upper diagram in FIG. 3 is a plan view of the conveyance path 17 as viewed from the direction perpendicular to the conveyance surface of the bills P, and the lower diagram is a side view as viewed from the horizontal direction with respect to the conveyance surface. The example illustrated in FIG. 3 shows switching between the conveyance path in which the banknote P is conveyed from the conveyance path 17c to the conveyance path 17d in FIG. 2 and the conveyance path in which the banknote P is conveyed from the conveyance path 17c to the conveyance path 17e. .

  As illustrated in FIG. 3, the blade mechanism 18 includes a blade 180, a shaft 182, and a swing selector 184.

  The blade 180 is a plate-shaped molded product made of a synthetic resin or the like, like the transport path 17. As shown in FIG. 3, the blade 180 has a shape corresponding to a space formed between the conveyance path 17c and the conveyance path 17d or the conveyance path 17e. For example, the blade 180 has notches corresponding to the plurality of protrusions at the end of the conveyance path 17c, the conveyance path 17d, and the conveyance path 17e on the side where the blade mechanism 18 is provided. This prevents the blade 180 and the conveyance path 17 from contacting each other when the blade 180 rotates.

  The shaft 182 is made of a rod-shaped metal, and is connected to the blade 180 through the center of the width of the blade 180 in the bill P conveyance direction. A swing selector 184 is connected to one end side of the shaft 182.

  The swing selector 184 is a drive unit that is connected to one end side of the shaft 182 and rotates the shaft 182 according to the control of the control unit 10.

  In the blade mechanism 18 according to the present embodiment, the blade 180 is rotatably provided with the shaft 182 as a rotation center. That is, in the blade mechanism 18, when the swing selector 184 is driven according to the control of the control unit 10, the blade 180 rotates and switches the conveyance path. At this time, the blade 180 is substantially parallel to either the transport path 17d or the transport path 17e according to the transport path.

  The automatic transaction apparatus 1 according to the present embodiment switches the transport path by rotating the blade 180 around the shaft 182 as in the transport path in the conventional blade mechanism 18 described in FIG.

  With reference to FIGS. 4-6, the antistatic mechanism of the automatic transaction apparatus 1 which concerns on this embodiment is demonstrated. FIG. 4 is an explanatory view showing an antistatic mechanism of the automatic transaction apparatus 1 according to the present embodiment. FIG. 5 is an exploded perspective view showing the blade mechanism 18 of the automatic transaction apparatus 1 according to the present embodiment. FIG. 6 is an explanatory diagram showing the switching of the conveyance path using the blade mechanism according to the present embodiment.

  Referring to FIG. 4, the blade mechanism 18 according to the present embodiment further includes a metal plate 186, a first discharge member 188, and a second discharge member 192 in addition to the blade mechanism 18 described with reference to FIG. 3. .

  The metal plate 186 is made of a plate-like metal and has a shape that covers the surface of the blade 180 that contacts the bills P. As shown in FIG. 5, the metal plate 186 is provided on the surface 180 a of the blade 180 on which the banknotes P are conveyed, and an end thereof is connected to a shaft 182 provided through the blade 180 by a method such as screwing. And electrically connected to the shaft 182. In FIG. 5, the metal plate 186 is shown as being provided only on the surface 180 a of the blade 180, but the present invention is not limited to this, and the metal plate 186 is on the opposite side of the surface 180 a of the blade 180. It may also be provided on the surface.

  The first discharge member 188 is made of a plate-like metal, and is connected to the other end of the shaft 182 opposite to the one end where the swing selector 184 is provided by a method such as screwing, and is electrically connected to the shaft 182. Conducted.

  The second discharge member 192 is made of metal and is provided on a surface of the housing sheet metal 19 that can come into contact with the first discharge member 188. The second discharge members 192a and 192b are provided at two locations so as to correspond to the two states of the first discharge member 188 after the shaft 182 is rotated in accordance with switching of the two patterns of the conveyance paths. The second discharge members 192 a and 192 b are connected to the housing sheet metal 19 by a method such as screwing, and are electrically connected to the housing sheet metal 19.

  In the example illustrated in FIG. 4, the second discharge members 192 a and 192 b have a shape in which a plate-like metal is bent at a substantially right angle, and one end side is connected to the housing sheet metal 19 by a method such as screwing. The The other ends of the second discharge members 192a and 192b, which are opposite to the one end, protrude from the housing sheet metal 19 and come into contact with the first discharge member 188.

  In the present embodiment, the blade mechanism 18 has two patterns of conveyance paths as illustrated in FIG. 1, and switches to the conveyance path of each pattern by rotating the shaft 182. In the antistatic mechanism according to the present embodiment, the first discharge member 188 contacts one of the second discharge members 192a and 192b in a state where the shaft 182 rotates and the transport path is switched. Therefore, the first discharge member 188 is electrically connected to the second discharge member 192 in a state where the transport path is switched. That is, the metal plate 186, the shaft 182, the first discharge member 188, the second discharge member 192, and the housing sheet metal 19 are in an electrically conductive state.

  Thereby, when the bill P is transported through the transport path, the metal plate 186 and the bill P come into contact with each other, so that the static electricity charged in the bill P is transferred from the metal plate 186 to the shaft 182 and the first discharge member 188. It moves to the housing sheet metal 19 via the second discharge member 192, and the static electricity charged on the banknote P is removed.

  FIG. 6 is an explanatory diagram showing the switching of the transport route according to the present embodiment. The upper diagram in FIG. 6 is a plan view of the conveyance path 17 as seen from the vertical direction of the conveyance surface of the bills P, and the lower diagram is a side view as seen from the horizontal direction of the conveyance surface. In the example illustrated in FIG. 6, as in FIG. 3, the conveyance path in which the banknote P is conveyed from the conveyance path 17 c to the conveyance path 17 d in FIG. 2, and the conveyance in which the banknote P is conveyed from the conveyance path 17 c to the conveyance path 17 e. Indicates switching to a route.

  As described with reference to FIG. 3, the conveyance path in the present embodiment is switched by rotating the blade 180 around the shaft 182. As shown by the solid line in the lower diagram of FIG. 6, the first discharge member 188 is in contact with the second discharge member 192 a in the transport path in which the bills P are transported from the transport path 17 c to the transport path 17 d. Then, it is in an electrically conductive state. From this state, when the blade 180 is rotated and the transport path for transporting the banknotes P from the transport path 17c to the transport path 17e, indicated by the two-dot chain line in the lower diagram of FIG. 6, is switched. The discharge member 188 comes into contact with the second discharge member 192a and becomes electrically conductive.

  In the antistatic mechanism according to the present embodiment, the first discharge member 188 and the second discharge member 192 are always in contact with each other and are electrically connected in a state where the conveyance path is switched by the rotation of the blade 180. It becomes a state. Therefore, when the bill P is transported in a state where the transport path is switched, the metal plate 186 to which the bill P is in contact with the casing sheet metal 19 is always electrically connected. The bills P that pass through are effectively neutralized.

  As shown in FIG. 1, since the housing sheet metal 19 is electrically connected to the frame GND line 28 and grounded, the charge transferred from the banknote P to the housing sheet metal 19 is not transferred to the frame GND line 28. And discharged to ground 30.

  In addition, the blade 180, the shaft 182, the first discharge member 188, the second discharge member 192, and the housing sheet metal 19 that are electrically connected to the automatic transaction apparatus 1 according to the present embodiment are made of metal. For example, the metal of these members may have high electrical conductivity, such as iron, low cost, and high availability.

  The antistatic mechanism according to the present embodiment has been described above. In the antistatic mechanism according to the present embodiment, the metal plate 186 provided on the contact portion, which is the surface with which the bills of the blade 180 come into contact, and the housing sheet metal include the shaft 182, the first discharge member 188, and the second. It is electrically connected to the discharge member 192. Thereby, when the charged banknote P is conveyed, the charged static electricity is discharged to the metal plate 186 in contact with the banknote P at a high speed. For this reason, also in the apparatus which conveys the banknote P which is a paper sheet medium at high speed like the automatic transaction apparatus 1, the discharge speed can be tracked with respect to a conveyance speed, and the banknote P can be fully discharged at high speed.

  Further, the antistatic mechanism according to the present embodiment is provided in the blade mechanism 18 provided in a plurality of locations of the automatic transaction apparatus 1. Thereby, the bill P is neutralized each time it passes through the plurality of blade mechanisms 18 on the transport path. Therefore, in the stacking unit such as each stacker that is the transport destination of the banknotes P, there is no sticking between the banknotes P and no sticking between the banknotes P and the molded product, so that stacking troubles can be reduced.

  Furthermore, the antistatic mechanism according to the present embodiment is provided at a plurality of locations on the transport path, so that each time the banknote P passes through the blade mechanism 18, the banknote P is sequentially neutralized. Thereby, the peak charge amount of the banknote P can be suppressed.

  Furthermore, the antistatic mechanism according to the present embodiment is provided in the blade mechanism 18 that is a part of the transport path. For this reason, the antistatic mechanism according to the present embodiment does not affect the conveyance behavior of the banknotes P as compared with a static elimination method using a static elimination brush that is not necessary for conveyance. In addition, the antistatic mechanism according to the present embodiment includes a case in which the antistatic mechanism is provided at a location other than the blade mechanism 18 because the banknote P always comes into contact with the blade mechanism 18 while the banknote P is transporting the transport path. In comparison, it can be surely removed.

  Furthermore, the antistatic mechanism according to the present embodiment is not mounted on the inside of the unit, such as addition of a sheet metal, a leaf spring and an FG wire, or a change of the conductive mold, but is performed by a method such as screwing outside the casing sheet metal 19. For example, mounting to the outside of the unit, such as adding two discharge members 192, or changing the blade mechanism 18 to the inside of the unit is easy. For this reason, for example, the antistatic mechanism can be easily mounted on the automatic transaction apparatus 1 that does not have the antistatic mechanism according to the present embodiment.

  Furthermore, the antistatic mechanism according to the present embodiment includes a metal plate 186, a shaft 182, a first discharge member 188, a second discharge member 192, and a housing sheet metal, which are paths through which the charge charged on the bill P moves. Are all made of metal. For this reason, compared with the case where the path along which the electric charge moves is made of a material having a large electric resistance such as a conductive resin, the discharge speed is increased, and even when the bills P are conveyed at a high speed, Static elimination can be performed.

<2. Second Embodiment>
Next, the automatic transaction apparatus 1 according to the second embodiment of the present invention will be described. The automatic transaction apparatus 1 according to the present embodiment is different from the automatic transaction apparatus 1 according to the first embodiment in the shape and configuration of the first discharge member 288 and the second discharge member 292, but other configurations and operations are the same. The same.

  First, with reference to FIGS. 7-8, the antistatic mechanism of the automatic transaction apparatus 1 which concerns on this embodiment is demonstrated. The antistatic mechanism according to the present embodiment is characterized in that the contact area between the first discharge member 288 and the second discharge member 292 is larger than that of the antistatic mechanism according to the first embodiment. FIG. 7 is a perspective view showing an antistatic mechanism of the automatic transaction apparatus 1 according to the second embodiment of the present invention. FIG. 8 is a schematic side view showing an antistatic mechanism of the automatic transaction apparatus 1 according to the present embodiment.

  In the example illustrated in FIGS. 7 and 8, the first discharge member 288 is a columnar metal having an elliptical cross section. The center of the first discharge member 288 is electrically connected to the shaft 182 by being connected to the other end of the shaft 182.
