Japanese Patent Laid-Open No. 10-203739

  In the device described in the above document, the card transport path is common at the time of card issuance and collection, and since the card issuance / collection can be performed at the entrance / exit of one card, the device configuration can be simplified. Yes. However, in this apparatus, when the card is collected, the accommodation card is raised and the card is taken in and accommodated in a space below it. In such a configuration, a mechanism for raising and lowering the accommodation card is necessary, and the height of the movement of the accommodation card is necessary, and the height of the device is more than the number of cards accommodated. As a result, even if the card transport path is simplified, it cannot be said that the overall configuration of the apparatus is simplified, and there is a disadvantage in reducing the size of the apparatus.

  Therefore, the present invention provides a card stacker apparatus that can simplify the configuration of the card stacker unit and can be miniaturized in the card stacker apparatus that has a function of accommodating a large number of cards and issuing the cards. The purpose is that.

  The present invention provides a stacker unit that accommodates a plurality of cards in a stacked state, a card introduction unit that communicates with the stacker unit, and a card stacker unit that is provided in the vicinity of the card introduction unit. The card insertion / discharge roller means for discharging the card from the card and the card on the one end side in the stacking direction among the plurality of cards accommodated in the stacker unit. Card transport roller means for taking in and storing in the stacker part while sandwiching the card inserted from the card introduction part between itself and the card at one end in the stacking direction, and inserting the card The transport nip portion of the discharge roller means is a direction on one end side in the card stacking direction in the stacker portion with respect to a card on one end side in the stacking portion in the stacker portion. Are offset, the card inserted from the card insertion / discharge roller means, characterized in that it is inserted obliquely with respect to the stacking direction one end side of the card.

  According to the present invention, one card is introduced into the apparatus from the card introduction unit by the card insertion / ejection roller means, and the card is interposed between the card transport roller means and the card accommodated in the stacker unit. It is guided and sandwiched between the two, and is accommodated in the stacker portion by the driving force of the roller means. The card thus collected and stored becomes a new card on one end side in the stacking direction in which the card conveying roller means is pressed. Next, the card stored in the stacker unit is sent out toward the card introduction unit by the reverse operation of the card transport roller unit, and is ejected and issued by the card insertion / ejecting roller unit that receives the card. The card transport roller means collects and stores the card, and performs the operations of discharging and issuing the card.

  In the present invention, when collecting the card, the card is introduced between the card conveying roller means and the card on one end side in the stacking direction of the stacker unit, and the card is held in the stacker unit while being sandwiched between the two. It is not necessary to provide a mechanism for separating the storage card from the card transport roller means, introducing the card into the empty space, and then returning the storage card to the original position. Further, it is not necessary to enlarge the device by the amount of moving the card. Therefore, a simple configuration and downsizing of the apparatus are possible.

  In the present invention, the stacker unit stacks and accommodates a plurality of cards in a substantially horizontal state, and the card transport roller means is disposed below the card accommodated at the lowermost part of the stacker unit. Thus, the card conveying roller means can be pressed against the lowermost card of the upper stacker unit, and the card introduction unit is offset below the lowermost card in the stacker unit. As mentioned.

  The card conveying roller means is disposed above the uppermost card of the stacker unit in which a plurality of cards are stacked and accommodated in a substantially horizontal state. A specific example is a form in which the roller means can be pressed against the lower card, and the card introduction part is offset upward from the uppermost card in the stacker part.

  Further, as a preferred embodiment of the present invention, the card insertion / discharge roller means is configured to separate the double-feed card properly when the card fed to the card introduction section from the stacker section by the card transport roller means has been double-feeded. The form provided with the double-feed card separation means which discharges | emits only the card which should be discharged | emitted is mentioned.

  Also, when a card is issued, in order to smoothly send the card from the stacker unit to the entrance / exit part, the card sent to the card introduction unit from the stacker unit by the card transport roller means is inserted into / extracted from the card introduction unit. It is preferable to provide a guide member for guiding the roller means.

In the present invention, as means for transporting the card, card transport roller means in the vicinity of the stacker section and card insertion / discharge roller means provided in the card introduction section are provided.
These roller means have a driving roller that contacts and conveys the card. In order to convey the card, the distance between the roller means is set to be shorter than the length of the card in the conveying direction. One of them is in contact with the card, and there are times when both roller means are in contact with the card in order to take over the conveyance. At that time, if the power of the driving rollers of both roller means is transmitted to the card, one driving roller is interfered by the other driving roller due to the difference in the conveying speed, and the card is distorted in conveying. Therefore, in order to prevent this problem and smoothly convey the card, the power of only the driving roller on the leading side in the card conveying direction is supplied to the card regardless of whether the card is ejected or stored. It is preferable to provide a power adjustment mechanism for transmission.

  According to the present invention, the conveyance nip portion of the card insertion / ejection roller means is offset in the direction of one end side in the card stacking direction in the stacker portion with respect to the card on the one end side in the card stacking direction in the stacker portion. Since the card inserted from the insertion / ejection roller means is inserted obliquely with respect to the card on the one end side in the stacking direction, the accommodation card can be taken in without being moved. There is an effect that it is possible.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[1] Configuration of Card Stacker Device FIG. 1 shows a cross section of one side of a card stacker device 1 according to an embodiment. Reference numeral 10 denotes a base, and 11 denotes a rectangular parallelepiped casing supported on the base 10. The casing 11 has a top plate portion 12, a front plate portion 13 and a rear plate portion 14, and the bottom portion is open. A pressing plate 16 is supported on the inner surface of the top plate 12 via a compression spring 15 in a suspended state, and a large number of cards C are stacked in a horizontal state between the pressing plate 16 and the base 10. Thus, the stacker unit 17 is accommodated. A large number of cards C are pressed downward by the compression spring 15 and the pressing plate 16, and the lowermost card C is brought into pressure contact with a transport driving roller (card transport roller means) 20 supported by the base 10. .

  On the upper surface of the base 10, an inclined surface 10 a that is inclined downward toward the front is formed at a portion facing the front end (left side in FIG. 1) of the lowermost card C. The inclined surface 10 a Between the lowermost card C is a card introduction portion 18 that expands in the vertical direction toward the front. A card transport path 19 is formed in front of the card introduction unit 18, and a first roller unit 30 and a second roller unit (card insertion / discharge) are sequentially inserted into the card transport path 19 from the front for card insertion / discharge. Roller means) 35 is disposed.

  The conveyance drive roller 20 is supported so as to rotate integrally with the drive shaft 25 supported by the casing 11, and is rotated in the direction of arrow RF by a drive motor (not shown). The conveyance driving roller 20 conveys the card C that is in pressure contact with the outer circumferential surface along the rotation direction, and the outer circumferential surface is made of rubber so as to reliably convey the friction. According to the transport driving roller 20, when rotating in the F direction, the lowermost card C of the stacker unit 17 that is in pressure contact is sent out to the left front in FIG. 1 and discharged from the card introduction unit 18. In addition, when a card C is inserted from the card introduction unit 18 while rotating in the R direction, the card C is sandwiched between itself and the lowermost card C and taken into the stacker unit 17 for storage. To do.

  The conveyance drive roller 20 includes a play mechanism (power adjustment mechanism) that does not transmit until the power of the drive motor reaches a certain angle range. FIG. 2 shows an idle mechanism, and a pin 26 orthogonal to the drive shaft 25 is fixed to one end of the drive shaft 25 of the transport drive roller 20 by press-fitting. A gear 27 connected to the drive motor 25 is rotatably mounted at one end portion. The gear 27 has a boss portion 27a that protrudes toward the drive shaft 25, and fan-shaped notches 27b are formed in the boss portion 27a at positions 180 degrees apart from each other. The ends of the pins 26 protruding from the drive shaft 25 are inserted into the notches 27b.

  With this play mechanism, as shown in FIG. 2 (c), the range in which the pin 26 hits from one end face of the notch 27b to the other end face becomes the play angle θ, and when the pin 26 does not hit the end face of the notch 27b, No. 27 runs idle so that no power is transmitted to the transport drive roller 20, and the power of the drive motor is transmitted to the drive shaft 25 and the transport drive roller 20 via the pin 26 from when the boss portion 27 a is engaged with the pin 26. It has become.

  The second roller unit 35 includes a driving roller 36 rotatably supported by the base 10, and a separation roller (a multi-feed card separating unit) disposed above and slightly in front of the driving roller 36 and in contact with the driving roller 36. 37. The second roller unit 35 sandwiches and transports the card C in the transport nip 35A between the drive roller 36 and the separation roller 37, and stores the card when the drive roller 36 rotates in the R direction, and issues the card when the drive roller 36 rotates in the F direction. It becomes. The outer peripheral surfaces of the drive roller 36 and the separation roller 37 are made of rubber so as to reliably convey the card C by friction. The position of the transport nip portion 35A is set to a position offset downward from the lowermost card C of the stacker portion 17, and the card C accommodated through the second roller unit 35 is the lowermost card. It is inserted obliquely toward the lower surface of C.

The first roller unit 30 includes a driving roller 31 that is rotatably supported by the base 10, and a driven roller 32 that is disposed above the driving roller 31 and contacts the driving roller 31. The first roller unit 30 sandwiches and transports the card C in the transport nip portion 30A between the driving roller 31 and the driven roller 32. Like the second roller unit 35, the driving roller 31 rotates in the R direction. Then, the card is issued and when it is rotated in the F direction, the card is issued. The outer peripheral surfaces of the driving roller 31 and the driven roller 32 are made of rubber to reliably convey the card C by friction. The conveyance nip portion 30A of the first roller unit 30 is located slightly below the conveyance nip portion 35A of the second roller unit 35, and a horizontal slit-shaped card insertion / A discharge port 19A is formed.
Each of the drive rollers 31 and 36 of the roller units 30 and 35 has a play mechanism in which a play angle at which power is not transmitted is set, similar to the transport drive roller 20.

  The separation roller 37 of the second roller unit 35 is driven and rotated following the drive roller 36. The rotation direction is the R direction when collecting cards and the F direction when issuing cards as shown in FIG. is there. When issuing a card, it is required that double feeding in which two or more cards C are simultaneously sent out while the cards C are overlapped does not occur. Therefore, the separation roller 37 incorporates a slip torque mechanism 40 and a one-way clutch mechanism 50 shown in FIG. 3 is an exploded view of (a) the separation roller 37, (b) the one-way clutch mechanism 50, (c) the slip torque mechanism 40, and (d) the separation roller 37, respectively.

  As shown in FIG. 3C, the slip torque mechanism 40 includes a guide shaft 41 having a flange 41b at one end of the shaft portion 41a, a stop ring 42 fixed to the other end of the shaft portion 41a of the guide shaft 41, The inner sleeve 43 attached to the shaft portion 41a, the ring-shaped friction pad 44 sandwiched between the inner sleeve 43 and the flange 41b, and the retaining ring 42 and the inner sleeve 43 are engaged with the inner sleeve 43. A compression spring 45 that is biased in the 44 direction and integrates the inner sleeve 43 with the guide shaft 41 via the friction pad 44 is fixed to the holder 31. The outer peripheral portion of the inner sleeve 43 is formed with a large diameter portion 43a, a medium diameter portion 43b, and a small diameter portion 43c from the flange 41b side to the stop ring 42. A diameter portion 43d is formed. The compression spring 45 is fitted in a space formed between the shaft portion 41a of the guide shaft 41 and the inner peripheral large diameter portion 43d.

  As shown in FIG. 3B, the one-way clutch mechanism 50 includes an inner cylindrical portion 51a that is slidably and rotatably mounted on the outer peripheral small diameter portion 43c of the inner sleeve 43, and an outer cylindrical portion 51b on the outer peripheral side thereof. The outer sleeve 51 includes a torsion coil spring 52 wound around the outer peripheral surfaces of the inner cylindrical portion 51 a and the outer peripheral intermediate diameter portion 43 b of the inner sleeve 43. When the torsion coil spring 52 is rotated in the winding direction, one end engages with the inner sleeve 43 and the other end engages with the outer sleeve 51.

  The slip torque mechanism 40 and the one-way clutch mechanism 50 share the inner sleeve 43, and the separation roller 37 is configured by combining the mechanisms 40 and 50 as shown in FIG. Further, a rubber cylindrical friction member 60 that contacts the driving roller 36 is mounted. According to the separation roller 37, the outer sleeve 51 is rotatable with respect to the fixed inner sleeve 43 integral with the guide shaft 41, and when the outer sleeve 51 rotates in the winding direction of the torsion coil spring 52, the torsion coil spring 52 is rotated. Is wound around the inner cylindrical portion 51a of the outer sleeve 51 and the inner diameter portion 43b of the inner sleeve 43, and the outer sleeve 51 is braked by the inner sleeve 43 in a fixed state and stops rotating.

  When the outer sleeve 51 rotates in the direction opposite to the winding direction of the torsion coil spring 52, the torsion coil spring 52 continues to rotate together with the outer sleeve 51 while being loosened. Rotates freely regardless. In this way, the separation roller 37 is locked in one direction by the one-way clutch mechanism 50, and freely rotates in the other direction. When a torque larger than the frictional force of the friction pad 44 is applied to the inner sleeve 43 in the locked state, the friction pad 44 slides and the separation roller 37 rotates in the winding direction of the torsion coil spring 52.

  The winding direction of the torsion coil spring 52 of the separation roller 37, that is, the rotating direction to lock, is set so as to coincide with the F direction which is the rotating direction of card issuance. As described above, in the separation roller 37, the card issuance is locked in the rotational direction of the card issuance, so that the double feeding of the card C to be issued is prevented as will be described later.

  Above the card introduction unit 18, a guide plate (guide member) 70 is provided for smoothly guiding the card C sent out from the stacker unit 17 to the transport nip portion 35A of the second roller unit 35 at the time of issuing the card. Yes. The guide plate 70 is divided and disposed on both sides of the separation roller 37 in the axial direction, and has a guide slope 71 that abuts the front end of the issued card C and guides it downward.

  As shown in FIG. 1, the second roller unit 35 is located between the axis of the separation roller 37 (that is, the axis of the guide shaft 41) and a horizontal line passing through the conveyance nip portion 35A (indicated by an arrow G in FIG. 1). 2), the vertical position is set so that the lowermost card C of the stacker portion 17 is positioned, and the separation roller 37 is positioned in the front-rear direction at a position close to the front end of the lowermost card C. The position is set. Due to this positional relationship, when the lowermost card C is issued, the separation roller 37 smoothly guides the card C to the transport nip portion 35A. Since the guide plate 70 is provided, the issued card C is more reliably guided to the transport nip portion 35A.

[2] Operation of Card Stacker Device The above is the configuration of the card stacker device 1 according to the embodiment. Next, the operation of this device 1 will be described with reference to FIGS. 4 and 5. In these figures, the stacker unit 17 in which a plurality of cards C are stacked and accommodated, the first roller unit 30 for card conveyance, the second roller unit 35, and conveyance drive are shown as components of the card stacker device 1. Only the roller 20 is extracted and shown.

(I) Accommodating Card The operation of accommodating the card C in the stacker unit 17 will be described with reference to FIG. First, as shown in (a), when one card C is inserted from the card insertion / discharge port 19A shown in FIG. 1, the drive rollers 31, 36 of the first roller unit 30 and the second roller unit 35 are inserted. Rotates in the card insertion direction, and the card C is drawn into the roller units 30 and 35. When the card C heads from the first roller unit 30 to the second roller unit 35, the leading end in the transport direction hits the drive roller 36 of the second roller unit 35, bends upward as the drive roller 36 rotates, and is separated from the drive roller 36. It is guided between the rollers 37. When the card is received, the separation roller 37 is driven to follow the insertion of the card C. Further, the card C proceeds obliquely upward toward the lowermost card C of the stacker unit 17 while passing through the card introduction unit 18, contacts the lower surface of the lowermost card C, and is fed backward while sliding. It is.

  Subsequently, as shown in (b), when the leading end of the card C in the transport direction enters between the transport driving roller 20 and the lowermost card C of the stacker unit 17, the transport driving roller 20 rotates in the collecting direction. As a result, the card is conveyed rearward while sliding on the lower surface of the lowermost card C as shown in (c) to (e), and is stored in the lowermost part of the stacker unit 17.

(Ii) Issuance of Card Next, the operation of ejecting and issuing the card C accommodated in the stacker unit 17 from the card introduction unit 18 will be described with reference to FIG. From the accommodated state of (a), the transport drive roller 20 and the drive rollers 36 of the first roller unit 30 and the second roller unit 35 are rotated in the card issuing direction. As a result, the lowermost card C of the stacker unit 17 is fed forward by the transport drive roller 20 while sliding on the upper card C in contact with the second roller unit 35 as shown in FIG. The driving roller 36 and the separation roller 37 are guided. At this time, the front end of the card C abuts against the guide slope 71 of the guide plate 70 and proceeds to the second roller unit 35 through the card introduction part 18 while bending downward. Subsequently, the card C is fed forward, sequentially forwarded by the contacting drive rollers 20, 36, 31 and discharged from the card insertion / discharge port 19A.

  When issuing a card, the lowermost card C of the stacker unit 17 needs to be sent out one by one. However, there are cases where double feeding is performed in a state where two or more sheets overlap each other. However, in this embodiment, the separation roller 37 is locked by the one-way clutch mechanism 50 shown in FIG. 3B when the card is issued and does not rotate. Therefore, when the double feed is about to occur, the separation roller 37 is applied to the card C to be issued. The overlapping second card C hits the separation roller 37 locked by the second roller unit 35 and is separated from the issuing card C entering between the driving roller 36 and the separation roller 37, and the double feed is performed. Is prevented. At the time of card collection, the separation roller 37 rotates freely in the collection direction, so that it rotates following the contacting card C and does not hinder the card collection operation.

  The above is the card collection and issue operation. Here, the driving rollers on which the card C receives the conveying driving force are the conveying driving roller 20 and the driving rollers 31 and 36 of the first roller unit 30 and the second roller unit 35. The speed at which C is conveyed is set so that the leading end side in the conveying direction of the card C is the fastest and gradually decreases toward the rear end side. This setting is applied to both cases of card collection and card issuance. That is, the conveyance speed at the time of card collection is the conveyance drive roller 20, the drive roller 36 of the second roller unit 35, and the first roller unit 30. The rotation speed at the time of card issuance is increased in the order of the driving roller 31 of the first roller unit 30, the driving roller 36 of the second roller unit 35, and the transport driving roller 20.

  In addition to such a speed difference setting, as described above, the drive rollers 20, 31, 36 are combined with the idler mechanism shown in FIG. When the card C is transported in contact with the card C, the card C is always transported by only one driving roller on the leading end side of the contact, and the driving roller on the rear side of the transport is in contact with the card C. However, power is not transmitted to the card C by the play mechanism. That is, in the driving roller on the rear side, the pin 26 exists in the notch 27b of the boss portion 27a shown in FIG. 2, and the pin 26 is in an idle state where it does not contact the end surface of the boss portion 27a. ing. As a result, the card C is not subjected to conveyance distortion due to power transmitted from a plurality of drive rollers, and the card C is smoothly conveyed by one drive roller on the conveyance leading end side.

  The card stacker device 1 is provided with a card sensor for detecting the transport position of the card C, and the drive rollers 20, 31, and 36 are driven and controlled according to the card detection position by the card sensor. When the card C is issued and collected, only the driving roller that contacts the card C may be rotated, and the other driving rollers may be stopped, and all of the three driving rollers 24, 32, and 34b may be You may rotate until conveyance is completed. Further, the card stacker device 1 has a function of reading data such as magnetic data written on the card C or writing data to the card C. Reading and writing of such data is performed by, for example, a stacker unit. 17 is performed with a magnetic head or the like provided in FIG.

[3] Effects of Card Stacker Device According to the card stacker device 1 of the present embodiment described above, when the card C is collected, the conveyance drive roller 20 and the card C at the lowermost part of the stacker unit 17 The card C is inserted between them, and the card C is sandwiched between the two and accommodated in the stacker unit 17. For this reason, there is no need for a storage card raising / lowering mechanism in which the storage card of the stacker unit 17 is raised and separated from the transport drive roller 20 and the card C is inserted into the vacant space and then the storage card is returned to its original position. . In addition, it is not necessary to enlarge the device by moving the accommodation card up and down. Therefore, a simple configuration and downsizing of the apparatus are possible.

  Further, when the card is issued, the card C is smoothly fed toward the second roller unit 35 from the card introduction unit 18 by bending the card C downward along the guide plate 70. As described above, between the axis of the separation roller 37 of the second roller unit 35 (that is, the axis of the guide shaft 41) and the horizontal line passing through the conveyance nip portion 35A of the second roller unit 35, Since the lowermost card C is positioned, the issued card C is smoothly guided to the transport nip portion 35A by the separation roller 37, and the guide plate 70 makes the transport of the card C smoother. . For example, when the lowermost card C of the stacker unit 17 is above the axis of the separation roller 37, when the card C is fed forward, the card C advances to the upper side of the separation roller 37, and the lower card For example, it is not guided to the introduction unit 18. The guide according to the present invention (the guide plate 70 in the above embodiment) is configured to guide the issued card C so as to smoothly proceed to the card introduction unit 18 even in the case of such an arrangement relationship. It is what is done.

  Further, when a card is issued, double feeding is prevented by the action of the separation roller 37 of the second roller unit 35 as described above. As a structure that can prevent double feeding, the second roller having the above configuration is used. In addition to the unit 35, for example, the gap between the drive roller 36 and the separation roller 37 is adjusted to such an extent that one card C passes but two does not pass. May be configured to rotate freely and not to rotate in the card issuing direction. As another example, there is a configuration in which the separation roller 37 is rotationally driven in the collection direction (R direction in FIG. 1) when a card is issued, although the configuration is the same as this. C is pushed backward by the separation roller 37 and is reliably separated.

  Further, as described above, the combination of increasing the conveyance speed by the three driving rollers 20, 31, and 36 that apply the conveyance force to the card C in order from the conveyance leading end side and the idle mechanism shown in FIG. Since the card C is always transported by one driving roller on the transport head side, the card C is not transported and the card C is transported smoothly. In addition, since the driving rollers 20, 31, and 36 are not loaded from the card C, the wear of the rubber is reduced, and it is difficult for the dirt to move from the driving rollers 20, 31, 36 to the card C.

  The card stacker device 1 is provided with a transport drive roller 20 below the stacker unit 17 and sends the card C to be collected obliquely upward from the card introduction unit 18 toward the lower surface of the lowermost card C. Although the configuration is the same as that of the configuration upside down, that is, the configuration of FIG. That is, the configuration is such that the conveyance drive roller 20 is disposed above the stacker unit 17 that stores a plurality of cards C stacked in a horizontal state, and the uppermost portion is driven by the force of the compression spring 15 disposed below the stacker unit 17. The card C is brought into pressure contact with the transport driving roller 20. Then, the card C to be collected is sent obliquely downward from the card introduction unit 18 toward the upper surface of the uppermost card C of the stacker unit 17.
