Description

  The present invention relates to a paper sheet stacking and feeding device.

  Conventionally, paper sheets fed from an external paper sheet conveying means are collected by being wound around a paper sheet collecting drum together with the tape, while the paper sheets accumulated on the paper sheet collecting drum are taped. At the same time, there is a paper sheet stacking and feeding device that is separated from the feeding tape and sent to an external paper sheet conveying means.

  In such a paper sheet stacking and feeding apparatus, the paper sheets are guided by being sandwiched between the input and output area immediately before winding the tape on the paper sheet stacking drum during stacking, while the paper sheets are stacked during the feeding. In some cases, an accumulation / separation guide member that separates paper sheets from a winding area around a drum is provided so as to be able to contact an outer peripheral surface of the winding area that faces an input / output area. Then, the accumulation and separation guide member is rocked in conjunction with the winding amount of the sequentially changing tape around the sheet accumulation drum (the accumulation amount of the sheets), thereby stably collecting the sheets. There is one that attempts to enable the feeding (see, for example, Patent Document 1).

  However, when the integrated separation guide member is of a swing type as described above, the position setting and swing range of the swing center may be limited due to interference with other members. In this way, if the swinging condition of the stacking separation guide member is limited, there is a possibility that stable stacking and feeding of the paper sheets cannot be realized with respect to the tape whose diameter changes with the winding amount.

  SUMMARY An advantage of some aspects of the invention is that it provides a paper sheet stacking and feeding device capable of stably stacking and feeding paper sheets.

  In order to achieve the above object, the invention according to claim 1 accumulates paper sheets fed from outside by winding them around a drum for paper sheet accumulation together with a tape, and accumulates them on the drum for paper sheet accumulation. In a paper sheet stacking and feeding device that feeds out the paper sheets together with the tape and separates the paper sheets from the tape and feeds the paper sheets to the outside, a contact roller for contacting a winding area of the tape on the paper sheet stacking drum is provided. The rotation axis of the paper sheet stacking drum is provided so as to be movable in the direction perpendicular to the axis.

  The invention according to claim 2 is the invention according to claim 1, wherein the sheet is guided by sandwiching the paper sheet with the entry / exit area immediately before winding the tape around the paper sheet accumulation drum at the time of stacking, while at the time of feeding. An accumulation / separation guide member for separating paper sheets from the winding region is provided so as to be able to contact an outer peripheral surface of the winding region facing the entry / exit region.

  The invention according to claim 3 is characterized in that, in the invention according to claim 2, the integrated separation guide member is fixed.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein a support member that supports a rotating shaft of the drum for collecting paper sheets, and the support member along the direction orthogonal to the axis. And a guide for guiding the support member to slide, and an urging member for urging the support member in the direction of the contact roller.

  According to the first aspect of the present invention, since the rotation shaft of the paper sheet stacking drum is provided so as to be movable in the axis orthogonal direction, the rotation axis of the paper sheet stacking drum is moved in the axis orthogonal direction. Thus, sufficiently stable accumulation and feeding of paper sheets can be realized.

  According to the second aspect of the invention, the paper sheets are guided by being sandwiched between the entry and exit areas immediately before winding the tape on the paper sheet collecting drum at the time of stacking, while the paper sheets are guided from the winding area at the time of unwinding. Since the separation / separation guide member to be separated is provided so as to be able to come into contact with the outer peripheral surface facing the entry / exit region in the winding region, even if there is a restriction on the swing of the accumulation / separation guide member, By moving the rotation axis of the drum in the direction perpendicular to the axis, sufficiently stable accumulation and feeding of the paper sheets can be realized.

  According to the invention of claim 3, since the rotation shaft of the paper sheet stacking drum is movable in the direction perpendicular to the axis and the stacking separation guide member is fixed, the tape is attached to the paper sheet stacking drum. It is possible to suppress the change in the contact position of the stacking separation guide member that is in contact with the outer peripheral surface facing the entry / exit region in the winding region of the tape on the paper sheet stacking drum, which occurs when the winding amount is changed. Therefore, sufficiently stable accumulation and feeding of paper sheets can be realized. In addition, since the collection and separation guide member can guide the paper sheets at a fixed position because they are fixed, it is possible to realize sufficiently stable collection and feeding of the paper sheets from this point. In addition, it is only necessary to move the drum for collecting paper sheets, and the complexity and cost of the structure can be suppressed.

  According to the fourth aspect of the invention, the supporting member that supports the rotating shaft of the paper sheet stacking drum and is guided and slid by the guide is biased in the direction of the contact roller by the biasing means. Therefore, the sheet stacking drum can be favorably moved in the direction of the contact roller with respect to a decrease in the amount of winding of the tape. In addition, it is possible to prevent the paper sheet collecting drum from being separated from the contact roller even if a small diameter difference occurs between a portion where the paper sheet is present and a portion where the paper sheet is not present.

It moves up and down with the uppermost upper limit position (refer to FIG. 7) in which the tape T is wound around the sort accumulation drum 81 together with the banknote S to the winding end position as the upper limit.

  The contact roller 106 contacts the paper sheet stacking drum 81 or the winding region Tb of the tape T so that the paper sheet stacking drum 81 can move following the winding amount of the tape T. It is preferable that the moving direction of the sheet stacking drum 81 is always set so as to form an obtuse angle including the case of 180 degrees with respect to a line connecting the position and the center of the sheet stacking drum 81. . Further, the separate guide member 33 makes at least the front end of the contact surface portion 59 of the separation front end portion 57 contact the paper sheet stacking drum 81 while the tape T is not wound around the paper sheet stacking drum 81. When the curvature of the outermost diameter portion of the winding region Tb of the tape T is changed due to the change in the winding amount of the tape T of the leaf accumulation drum 81, it is elastically deformed accordingly, and in that case as well, the paper At least the tip of the contact surface portion 59 is always brought into contact with the outermost diameter portion of the winding region Tb of the tape T of the leaf accumulation drum 81. In addition, the separation leading end portion 57 is set so that the separation guide surface portion 60 always forms an acute angle with the portion that contacts the contact surface portion 59 of the sheet stacking drum 81 or the winding region Tb of the tape T. . Further, the relief surface portion 56 of the separate guide member 33 is configured to fully accumulate the tape T together with the banknotes S to the winding end position when the winding region Tb of the tape T is maximized, in other words, the paper sheet accumulation drum 81. Even in this state (see FIG. 7), the winding region Tb is curved so as not to contact.

  As shown in FIG. 3, the width of the lower guide member 34 is substantially equal to the axial length of the paper sheet stacking drum 81, and the back side of the lower end position of the paper sheet stacking drum 81 (conveyance). It extends to the side opposite to the road 27). As shown in FIGS. 3 and 5, a pair of auxiliary rollers 107 and 107 are rotatably provided directly below the lower guide member 34 via support shafts 108 and 108. The support shafts 108 and 108 are supported by the lower guide member 34, and the auxiliary rollers 107 and 107 pass through the lower guide member 34 and protrude into the passage 32, near the lower end of the paper sheet stacking drum 81. It is provided so that it can contact. The contact roller 106 is provided between the auxiliary rollers 107 and 107.

  These auxiliary rollers 107 and 107 are provided so as to be able to come into contact with both outer positions of the tape T in the axial direction of the paper sheet stacking drum 81, and are separated from each other as the distance from the transport path 27 increases. It is inclined with respect to the extending direction and arranged in a square shape in plan view. As a result, the auxiliary rollers 107 and 107 spread the banknotes S wound around the paper sheet stacking drum 81 together with the tape T in the left-right direction. The auxiliary rollers 107 and 107 are arranged at positions where they contact the outer peripheral surface of the paper sheet stacking drum 81 when the paper sheet stacking drum 81 is at the reference position where the outer peripheral surface contacts the contact roller 106. Has been.

  As shown in FIG. 3, the lower roller 36 is rotated by the contact tension of the tape T, that is, rotates with the traveling of the tape T, and the upper rollers 35, 35 overlap the lower roller 36 or the tape T. The banknote S that is moved as a unit is moved along with the travel. 2 for guiding the tape T is also rotated by the contact tension of the tape T, and the auxiliary rollers 107 and 107 shown in FIG. 3 and FIG. The banknote S that is superposed on the tape T and moves integrally with the tape T is rotated along with the traveling of the banknote S. In addition, the contact roller 106 rotates in contact with the paper sheet stacking drum 81 or the winding region Tb of the tape T.

  As shown in FIG. 1, a motor 111 is provided below the tape rewind drum 101 in the above-described accumulation space 20. As shown in FIG. 5, the drive shaft 112 of the motor 111 has a gear 113. Is fixed. The gear 113 is arranged on the drive system space 14 side as shown in FIG. Further, a rotating shaft 114 extending in the left-right direction is rotatably supported on the support plate 13, and a gear 115 shown in FIG. 5 that meshes with the gear 113 of the motor 111 is fixed to the accumulation space 20 side of the rotating shaft 114. Has been. Further, as shown in FIG. 1, a gear 116 with a one-way clutch is attached to a portion of the rotating shaft 114 disposed in the drive system space 14. On the entrance / exit 31 side of the gear 116, a rotating shaft 118 extending in the left-right direction is connected to the side plate 12 and the rear side plate 19 via a pair of bearings 119, 119, as shown in FIGS. 1 and 2. As shown in FIG. 1, a gear 120 and a driving pulley 121 that are engaged with the gear 116 are fixed to a portion that is rotatably supported and is disposed in the drive system space 14 of the rotating shaft 118.

  A pin 125 extending in the left-right direction for connecting the side plate 12 and the support plate 13 is provided at a position between the rotary shaft 118 and the rotary shaft 80 of the paper sheet stacking drum 81. A plate-like position adjusting member 126 is rotatably supported on the support plate 13 side of 125. The position adjustment member 126 extends downward from the pin 125, and an adjustment pulley 127 is rotatably supported in a lower portion of the position adjustment member 126 via a support shaft 128 extending in the left-right direction in the drive system space 14. Further, as shown in FIG. 5, a tension coil spring (spring member) 130 is interposed between the lower portion of the position adjustment member 126 and the support plate 13, and the position adjustment member 126 is caused by the tension coil spring 130. The adjustment pulley 127 is urged in the direction in which the adjustment pulley 127 approaches the rotating shaft 100 of the tape rewinding drum 101.

  The pulley 97 fixed to the rotating shaft 80 of the paper sheet collecting drum 81, the pulley 103 fixed to the rotating shaft 100 of the tape rewinding drum 101, the adjusting pulley 127, and the driving pulley 121 are arranged in the left-right direction. The endless drive belt 131 is hung on these. The drive belt 131 is hung on the outer side of each of the pulley 97, the pulley 103, and the drive pulley 121, and is hung on the inner side of the adjustment pulley 127.

  As a result, during the winding operation in which the motor 111 rotates forward, the drive pulley 121 is driven in a predetermined banknote stacking direction (counterclockwise direction in FIG. 5), and the pulley 97 and the pulley via the drive belt 131 are driven. 103 also rotates in the same direction. As a result, the sheet stacking drum 81 and the tape unwinding drum 101 rotate in the same direction, and the tape T is unwound by the tape unwinding drum 101 while the tape T is being wound by the sheet stacking drum 81. become. On the other hand, during the rewinding operation in which the motor 111 rotates in the reverse direction, the drive pulley 121 is driven in a predetermined bill feeding direction (clockwise direction in FIG. 5), and the pulley 97 and the pulley 103 are also connected via the drive belt 131. It will rotate in the same direction. Thus, the tape rewind drum 101 and the paper sheet stacking drum 81 are also rotated in the same direction, and the tape T is fed out by the paper sheet stacking drum 81 while the tape T is wound up by the tape rewind drum 101. become.

  As described above, since the rotation shaft 80 of the paper sheet collecting drum 81, that is, the pulley 97 is movable, the distance between the pulley 97, the pulley 103, and the driving pulley 121 changes. As the distance changes, the tension coil spring 130 constantly balances the tension of the driving belt 131 with its urging force while the position adjusting member 126 is swung around the pin 125 and the adjusting pulley 127 is moved. Yes. As a result, the position adjusting member 126, the adjusting pulley 127, and the tension coil spring 130 always generate tension on the driving belt 131 regardless of the position of the paper sheet stacking drum 81, thereby loosening the driving belt 131. A tension mechanism 132 that always generates tension is configured. In other words, the tension mechanism 132 is an adjustment pulley without changing the actual overall length of the drive belt 131 with respect to the belt length necessary for interlocking the pulley 97, the pulley 103, and the drive pulley 121 that increase or decrease gradually. This is achieved by interlocking displacement of the position 127.

  Next, the operation of the paper sheet stacking and feeding apparatus 11 according to this embodiment will be described.

  When stacking the banknotes S, as shown in FIG. 6, the paper sheet stacking drum 81 at the lowest reference position is driven in a predetermined banknote stacking direction (in FIGS. The tape T is wound up by rotating in the clockwise direction). At this time, the tape rewinding drum 101 is also rotated in the same direction, and the tape T is fed out. Then, as shown in FIG. 3, the banknotes S that have been fed one by one from the external transport path 27 pass through the passage 32 from between the inclined guide surface portion 41 and the inclined guide surface portion 52 of the entrance / exit 31. In the passage 32, the upper roller 35, 35 and the lower roller 36 overlap the tape T with the approximate center position in the short side direction and transport it together with the tape T.

  At this time, the banknote S moves in the linear entering / exiting area Ta together with the portion of the tape T overlapping with this. At that time, the lower surface of the bill S is guided by the entry / exit area Ta of the tape T and the main guide surface portion 40 of the lower guide member 34, and the upper surface of the bill S is guided mainly by the intermediate guide surface portion 61 of the separate guide member 33. Move. And the banknote S enters between the entrance / exit area Ta of the tape T and the winding area Tb already wound around the paper sheet stacking drum 81. Then, the portion on the input / output region Ta side that becomes the new winding region Tb of the tape T is wound around the winding region Tb of the tape T that is already wound around the center side of the paper sheet stacking drum 81. The banknote S is sandwiched between them. In this way, the banknotes S are sequentially collected on the paper sheet stacking drum 81 by being wound around the paper sheet stacking drum 81 together with the tape T. At this time, as described above, the separate guide member 33 has the intermediate guide surface portion 61 in the banknote S with the entry / exit area Ta and the lower guide member 34 immediately before winding the tape T around the paper sheet stacking drum 81. Guidance across the.

  When the banknotes S are sequentially wound around the paper sheet stacking drum 81 in the reference position in this manner together with the tape T, the outer diameter (drum diameter) of the winding region Tb of the tape T is set according to the winding amount. Although the outer peripheral surface of the winding region Tb is in contact with the contact roller 106, the sheet stacking drum 81 is moved upward from the contact roller 106. You will receive power. As a result, the support members 85 and 85 that support the rotating shaft 80 of the paper sheet stacking drum 81 are linked to an increase in the amount of winding of the tape T, and the front and rear guide edge portions of the guide spaces 83 and 83, respectively. Then, the rotary shaft 80 is moved upward along the lines 84 and 84 to raise the rotary shaft 80 against the urging force of the compression coil springs 96 and 96 by linear movement (see FIG. 7). At this time, since the compression coil springs 96 and 96 always urge the support members 85 and 85 downward, even if a minute diameter difference occurs between the portion with the banknote S and the portion without the banknote S, the tape T The winding region Tb is restricted from being separated from the contact roller 106 and the contact surface portion 59 of the separate guide member 33. At this time, since the separate guide member 33 is fixed, the contact point with the tape T is the holding start point of the banknote S, that is, the entry / exit region Ta, which is the entry / exit start point of the tape T, and the winding region Tb. Regardless of the winding amount of the tape T, a substantially constant positional relationship is maintained with respect to the boundary position.

  Conversely, when the banknote S is fed, the tape rewinding drum 101 rotates in a predetermined banknote feeding direction (counterclockwise direction in FIGS. 6 and 7), thereby winding only the tape T from one side. At this time, the paper sheet stacking drum 81 is also rotated in the same direction, and the tape T and the banknote S are fed out. As a result, the banknotes S accumulated on the paper sheet stacking drum 81 are separated from the paper sheet stacking drum 81 at the outermost periphery of the winding area Tb of the tape T, and the portion overlapping the banknote S is separated from the paper sheet stacking drum 81. , The pressing of the tape T against the tape T is released. Then, the banknote S is in the vicinity of the paper sheet stacking drum 81 and is in the vicinity of the separation guide surface portion of the separation leading end portion 57 of the separate guide member 33 that is in contact with the outer peripheral surface facing the entry / exit region Ta in the winding region Tb. Riding on 60 is separated from the winding region Tb and faces the intermediate guide surface 61 on the transport path 27 side of the separation guide surface 60 of the main plate portion 46 of the separate guide member 33 on the lower side. It is guided by the main guide surface portion 40 of the lower guide member 34 and the entrance / exit area Ta of the tape T, and moves together with the entrance / exit area Ta of the tape T in a direction away from the sheet stacking drum 81. That is, when the portion of the tape T holding the bill S reaches the entry / exit region Ta, the tip of the bill S held by this portion is about to move while being attached to the winding region Tb of the tape T. The separation tip 57 of the separate guide member 33 that is in contact with the winding region Tb is separated so as to be scraped from the winding region Tb of the tape T.

  And the banknote S which is guided and moved by the intermediate guide surface portion 61 of the separate guide member 33, the main guide surface portion 40 of the lower guide member 34, and the entry / exit area Ta of the tape T is finally moved to the upper rollers 35, 35 and the lower When projecting from between the rollers 36, it is separated from the tape T folded back by the lower roller 36 by being guided by the inclined guide surface portion 52 of the separate guide member 33 and the inclined guide surface portion 41 of the lower guide member 34, As it is, it is fed out to the front outside conveyance path 27.

  As described above, when the tape T is fed out from the paper sheet stacking drum 81 together with the banknote S, the outer diameter of the winding region Tb of the tape T is gradually reduced according to the feeding amount. Since the lower side of the outer peripheral surface of the region Tb is in contact with the position-fixed contact roller 106, the support members 85 and 85 that support the rotating shaft 80 of the sheet stacking drum 81 are used for winding the tape T. In conjunction with the decrease in the applied amount, the weight of the paper sheet stacking drum 81 and the urging force of the compression coil springs 96, 96 are lowered along the front and rear guide edge portions 84, 84 of the guide spaces 83, 83, respectively. To move the sheet stacking drum 81 down to the reference position by linear movement. Also at this time, since the compression coil springs 96, 96 always urge the sheet stacking drum 81 downward, even if a slight difference in diameter occurs between the part with the banknote S and the part without the banknote S. The winding region Tb of the tape T is restricted from being separated from the contact roller 106 and the contact surface portion 59 of the separate guide member 33. Also at this time, since the separate guide member 33 is fixed, the contact point with the tape T is the separation start point of the bill S, that is, the entry / exit region Ta which is the entry / exit start point of the tape T, and the winding region Tb. A substantially constant positional relationship is maintained regardless of the winding amount of the tape T.

  In the above, since the linear entry / exit area Ta of the tape T is substantially in the horizontal direction, the sheet stacking drum 81 has an intersecting direction intersecting the entry / exit area Ta above the entry / exit area Ta, specifically Is linearly moved in the vertical direction, which is a substantially orthogonal direction. As a result, the front and rear guide edge portions 84 and 84 of the pair of guide spaces 83 and 83 provided in the side plate 12 and the side plate 17 extend along the crossing direction in which the support members 85 and 85 are substantially orthogonal to the entry / exit region Ta. The compression coil springs 96 and 96 urge the support members 85 and 85 downward, that is, in the direction of the entry / exit region Ta.

  As described above, the paper sheet stacking drum 81 maintains its rotation in conjunction with the amount of winding of the tape T around the paper sheet stacking drum 81 when the banknote S is stacked and when it is fed out. In the state, the reference position and the upper limit position are set as limits respectively, and a straight line is moved between them. As a result, the distance between the pulley 97, the pulley 103, and the drive pulley 121, that is, the belt length for rotating the paper sheet stacking drum 81 and the tape rewinding drum 101 is slightly increased or decreased.

  Specifically, as described above, as the winding amount of the tape T around the paper sheet stacking drum 81 increases, the paper sheet stacking drum 81 moves in a linear manner in conjunction with this. When the amount of wrapping of the tape T around the paper sheet stacking drum 81 decreases linearly with the upper limit position being pushed so as to be pushed upward substantially orthogonal to the region Ta, the paper sheet is linked with this. The similar accumulation drum 81 linearly moves with the reference position as a limit so as to return downward substantially perpendicular to the linear entry / exit area Ta. In these cases, the shortest necessary belt length required to connect only the pulley 97, the pulley 103, and the drive pulley 121 is the displacement of the paper sheet stacking drum 81 that linearly moves from the reference position to the upper limit position. As the sheet stacking drum 81 moves linearly from the upper limit position to the reference position, the sheet stacking drum 81 increases gradually.

  Correspondingly, the position adjusting member 126 of the tension mechanism 132 is urged so as to be swingable by the tension coil spring 130 around the pin 125 pivotally supported in the vicinity of the upper portion thereof. In the process in which 81 is displaced upward with the upper limit position as the limit, the position adjustment member 126 rotates in the clockwise direction in FIG. 5 against the biasing force of the tension coil spring 130 in conjunction with the displacement. The position of the adjusting pulley 127 to be displaced is displaced, and the opening angle of the V-shaped surplus portion of the drive belt 131 is increased to cope with the reduction of the required belt length. Further, in the process in which the paper sheet stacking drum 81 is displaced downward with respect to the reference position, the position adjusting member 126 is rotated counterclockwise in FIG. 5 by the urging force of the tension coil spring 130 in conjunction with the displacement. By doing so, the position of the adjusting pulley 127 that supports the shaft is displaced, and the opening angle of the V-shaped surplus portion of the drive belt 131 is reduced to cope with an increase in the required belt length.

  According to the paper sheet stacking and feeding apparatus 11 according to the present embodiment described above, the rotation shaft 80 of the paper sheet stacking drum 81 is provided so as to be movable in the direction orthogonal to the axis, and therefore the separate guide member 33. Even if there is a restriction on the swing of the paper, by moving the rotation shaft 80 of the drum 81 for collecting paper sheets, it is possible to realize a sufficiently stable stacking and feeding of the banknote S, and banknotes with folds, curls, etc. Even if it is S, accumulation and feeding can be reliably performed.

  Specifically, since the rotation shaft 80 of the paper sheet stacking drum 81 is movable in the direction perpendicular to the axis and the separate guide member 33 is fixed, the tape T is wound around the paper sheet stacking drum 81. Holding of the bill S at the contact position of the separate guide member 33 that contacts the outer peripheral surface facing the entry / exit region Ta in the winding region Tb of the tape T around the paper sheet stacking drum 81 that occurs when the amount changes. It is possible to suppress a change with respect to the boundary position between the entry / exit area Ta and the winding area Tb, which is the start point and the separation start point. Therefore, it is possible to realize sufficiently stable banknote accumulation and feeding.

  In addition, since the separate guide member 33 is fixed, it is only necessary to move the paper sheet stacking drum 81, so that the complexity and cost of the structure can be suppressed, and the manufacturing cost can be reduced.

  Further, support members 85 and 85 which support the rotating shaft 80 of the paper sheet stacking drum 81 and which are guided and slid by the front and rear guide edge portions 84 and 84 are respectively pressed by the compression coil springs 96 and 96. Since the sheet is urged in the direction of 106, the sheet stacking drum 81 can be favorably moved in the direction of the contact roller 106 with respect to a decrease in the winding amount of the tape T.

  Further, since the support members 85 and 85 are urged in the direction of the contact roller 106 by the compression coil springs 96 and 96, a minute diameter difference is generated between the portion with the banknote S and the portion without the banknote S. In addition, the sheet collecting drum 81 can be prevented from being separated from the contact roller 106 and the separate guide member 33.

  In the present embodiment, the position adjustment member 126 of the tension mechanism 132 is urged by the tension coil spring 130 to be displaced in conjunction with the movement of the pulley 97, but other urging members can be used as a matter of course. Alternatively, the position adjustment member 126 itself may have an interlocking displacement mechanism.
