Yes.

JP 2009-271810 A

  However, when the paper is discharged in the conventional input / separation mechanism, the blade roller portion is also stopped as the second roller unit is maintained in the stopped state, and the paper discharge path is the blade roller. There is a problem in that it is obstructed by the blades of the part, leading to poor discharge of paper sheets such as misfeeds. This defect is likely to occur especially when paper sheets that are weakly stiff are transported, when the humidity is high, or when the paper sheets are folded, etc., because the discharged paper sheets must push away the blades. .

  As a configuration for reducing the discharge failure caused by the blade roller portion, it is considered as one effective means to reduce the number of blade portions formed in the circumferential direction of the blade roller portion. In order to prevent the inserted paper sheets from interfering with the succeeding paper sheets, the inserted paper sheets are moved by the blade roller unit until the succeeding paper sheets are inserted. When the number of blade portions formed on the blade roller portion is small, the loading assist function by the blade roller portion is reduced and the retraction to the retract position is in time. Therefore, there is a problem that an accumulation failure such as a jam occurs.

  Further, as another configuration for reducing the discharge failure, it can be considered as one effective means to set the rigidity of the blade portion of the blade roller portion low, but as the rigidity of the blade portion is decreased, the blade roller portion Since the force to push out the paper sheets to the accumulation space is reduced, there is a risk of hindering the appropriate insertion of the paper sheets.

  Further, as a configuration other than the above to avoid the discharge failure, a portion where the blade portion is not disposed is set in the blade roller portion, and the blade portion does not interfere with the path of the paper sheet when discharging the paper sheet. Thus, a configuration in which the blade roller unit and the second roller unit are rotated and positioned is considered as one effective means, but this configuration requires a complicated configuration using a sensor, a special drive motor, or the like. There is a problem that the apparatus becomes large and the manufacturing cost increases. In addition, in this configuration, since the blade roller unit and the second roller unit are always positioned in a constant posture, the second roller unit is locally worn, and this separation wear reduces the separation function. End up.

  The present invention has been made paying attention to such a problem, and the purpose thereof is to stably avoid paper discharge defects caused by the path of the paper sheets being obstructed by the blades of the blade roller section, and to stabilize the paper. It is to provide a paper sheet processing apparatus that realizes input and discharge of leaves.

  In order to achieve this object, the present invention takes the following measures.

That is, the paper sheet processing apparatus according to the present invention is configured to store a paper sheet and a paper sheet into and out of the storage unit, and separate and discharge the stored paper sheets one by one. a sheet processing apparatus comprising; and a charged separation mechanism, the closing separation mechanism includes a first roller unit and a pair of roller units comprising a second roller units arranged in the thickness direction both sides The first roller unit moves the paper sheets in the discharge direction while the two roller units rotate in the direction to move the paper sheets in the loading direction. The second roller unit is configured to rotate and rotate in a direction in which the second roller unit stops or moves the paper sheets in the loading direction, so that the paper sheets are separated and discharged one by one. Accumulation of leaves in the storage unit Blade roller portion having a blade portion made of an elastic member for exhalation to between is rotatable together with the first roller unit the first to the rotation axis of the roller unit, first when turning on the sheet A roll-up preventing member for restricting the roll-up of the paper sheet accompanying the rotation of the first roller unit is on the side facing the second roller unit with the paper sheet to be inserted therebetween, and the first roller unit Is positioned closer to the storage portion than the rotating shaft of the first roller unit, and is provided at a position overlapping the blade portion in a side view when the blade roller portion rotates. It is characterized by comprising adjacent portions .

According to this configuration, when the paper sheet is inserted, the roll-up preventing member restricts the winding of the paper sheet due to the rotation of the first roller unit, and the blade roller section having the blade section made of the elastic member includes the paper sheet. The paper sheets that are input by rotating about the same axis as the first roller unit that moves the paper in the input direction are ejected to the accumulation space in the storage unit, and the paper sheets are appropriately input to the storage unit, while the paper Since the blade roller unit rotates about the same axis as the first roller unit that moves the paper sheet in the discharging direction when the leaf is discharged, the blade roller unit does not interfere with the path of the paper sheet, and the paper sheet and the blade. It is possible to prevent discharge failure of paper sheets such as misfeed due to interference with the roller portion. In addition, since the blade roller part does not interfere with the path of the paper sheet, it is not necessary to reduce the number of blade parts of the blade roller part or reduce the rigidity of the blade part in order to reduce discharge failure due to the path obstruction. By reducing the number of blades, avoiding the failure to accumulate in the stacking space in time, and avoiding the occurrence of defective stacking such as jams, or reducing the force of the blade roller unit to push out the sheets into the stacking space. Thus, the paper sheets can be accurately put into the storage unit.

  In particular, when the second roller unit is stopped when the paper sheet is discharged, the blade roller portion is provided not in the second roller unit but in the first roller unit, so that the paper sheet is discharged. It is no longer necessary to provide a complicated mechanism for positioning and controlling the second roller unit in a posture in which the blade roller part does not interfere with the path of the paper sheet, and the configuration for preventing the above-described conveyance failure is reduced in size and manufacturing cost. This can be realized with a simple configuration. In this case, since the second roller unit can be stopped in an arbitrary rotation posture, the second roller unit is always worn in a constant posture, and thus the second roller unit is locally worn. And the reduction of the separation function due to uneven wear can be prevented.

  In order to reduce a new conveyance failure that occurs when the blade roller unit presses the sheets toward the second roller unit, the blade roller unit is arranged along the width direction of the sheets. It is preferable that a plurality of blade portions formed on each blade roller portion are arranged so that positions in the circumferential direction are different from each other.

  In the present invention, as described above, the blade roller unit rotates coaxially with the first roller unit when discharging the paper sheet, so that the blade roller unit does not obstruct the path of the paper sheet, and the paper sheet It becomes possible to prevent discharge failure caused by interference between the blade and the blade roller portion.

  In addition, since the blade roller part does not interfere with the path of the paper sheet, it is not necessary to reduce the number of blade parts of the blade roller part or reduce the rigidity of the blade part in order to reduce discharge defects due to the path obstruction. By reducing the number of blade parts, avoiding the accumulation failure such as jam without evacuating to the accumulation space in time, or by appropriately applying the force that the blade roller part ejects the paper sheets to the accumulation space, Paper sheets can be accurately put into the storage unit.

  Further, since the blade roller unit is provided not in the second roller unit but in the first roller unit, the second roller unit is positioned so that the blade roller unit does not obstruct the path of the paper sheet when the paper sheet is discharged. There is no need to provide a complicated mechanism for rotating and positioning control, and the configuration for preventing the above-mentioned conveyance failure can be realized with a simple configuration while reducing the size of the apparatus and reducing the manufacturing cost. In this case, since the second roller unit can be stopped in an arbitrary rotation posture, the second roller unit is always worn in a constant posture, and thus the second roller unit is locally worn. It is possible to prevent the separation function from being reduced due to uneven wear.

  In each safe A (B, C), as shown in FIG. 4, a primary storage unit a1 (b1, c1) and a storage unit a2 (b2, c2) that can store paper sheets such as banknotes in a bundled state. ) Is formed. The storage part a2 (b2, c2) is provided with a reciprocating part fo using a fork that reciprocates up and down by the power of a drive motor (not shown). The reciprocating part fo constitutes the storage part a2. A storage space sp surrounded by a wall surface wl (see FIGS. 7 to 9) is divided into two upper and lower spaces, and a secondary storage portion a3 (b3, b) for temporarily storing the upper space in the upper space c3). Then, with each of these parts a1, a2 and a3, at the time of the transaction, paper sheets such as banknotes inserted from the insertion slot 11 shown in FIG. 3 are inserted one by one into the primary holding unit a1 (b1, c1), and the transaction is confirmed. Paper sheets such as banknotes are held one by one from the storage unit a2 (b2, c2) and are bundled from the primary holding unit a1 (b1, c1) when the transaction is confirmed. The paper sheets in a state are discharged in a lump, and the discharged paper sheets are loaded into the secondary holding section a3 (b3, c3) by belt conveyance so that the paper sheets can be held until the start of the next transaction. Yes. The storage portion a2 (b2, c2) is provided with a backup plate bp that urges the stored paper sheet Pa upward (near the input / output portion) (see FIGS. 7 to 9). .

  In order to realize this operation, as shown in FIG. 4, in each of the safes A to C, paper sheets Pa such as banknotes transported from the outside via the transport path 21 are batch-loaded into the storage unit a2. In addition, a loading / separating mechanism 3 is provided for separating the sheets in the storage section a2 one by one and discharging them toward the transport path 21.

  The input / separation mechanism 3 includes a pair of input roller units 32 and 33 having a driving force disposed on both sides in the thickness direction of the paper sheet Pa, and a feed roller unit 30 that is a first roller unit that similarly forms a pair. And a gate roller unit 31 which is a second roller unit and a pickup roller unit 34, and the paper sheets Pa are inserted in or discharged from the roller units 30 to 34 while the paper sheets Pa are sandwiched between them. It is configured to be energized.

  Specifically, as shown in FIGS. 5 and 6, the feed roller unit 30 includes a rotary shaft 30s that is rotatably mounted using the safe A (B, C) as a scaffold, and a comb fixed to the rotary shaft 30s. 5 mainly includes rollers 30a to 30c and a feed gear 30g fixed to the rotation shaft 30s. The power of a drive source such as a motor (not shown) is transmitted to the feed gear 30g to rotate around the rotation axis Cn1. It rotates in the direction of arrow Y1 or arrow Y2. An arrow Y1 direction in FIG. 5 is a direction in which the paper sheet is moved in the loading direction, and a Y2 direction in FIG. 5 is a direction in which the paper sheet is moved in the discharge direction.

  As shown in FIGS. 5 and 6, the gate roller unit 31 includes a balance unit 35 that rotatably supports the rotary shaft 31s using the safe A (B, C) as a scaffold, and comb rollers 31a to 31a fixed to the rotary shaft 31s. 31b and a gate gear 31g that is fixed to the rotating shaft 31s and meshes with the feed gear 30g. The gate gear 31g is attached to the rotating shaft 31s via a one-way clutch (not shown) and the rotating shaft 31s is not shown. 5, the gate roller unit 31 is moved to the direction indicated by the arrow Y3 in FIG. 5 only when the feed roller unit 30 is rotated in the direction indicated by the arrow Y1 in FIG. 5 (the direction in which the sheets are moved in the loading direction). Direction (the direction in which the paper is moved in the loading direction) And it is configured so that the gate roller unit 31 maintains the stopped state without rotating in the case of La unit 30 is rotated in the arrow Y2 direction in FIG. 5 (a direction of moving the paper sheets in the discharge direction). The balance unit 35 is attached to the safe A (B, C) so as to be rotatable around a rotation axis Cn3 substantially parallel to the rotation axis Cn1 of the feed roller unit 30, and the feed roller unit 30 and the gate roller The unit 31 is relatively perspective. The balance portion 35 is urged by a coil spring (not shown) in the direction of arrow Y4 shown in FIGS. 7 and 8, that is, the direction in which the gate roller unit 31 is brought closer to the feed roller unit 30. As shown in FIG. 7, when the bundled paper sheets Pa (Stack) are put into the storage section a2, the urging force is pressed by the gate roller unit 31 to the bundle of paper sheets Pa (Stack). Accordingly, the strength is set such that the feed roller unit 30 and the gate roller unit 31 are separated from each other.

Then, as shown in FIG. 7, the feed roller unit 30 and the gate roller unit 31 rotate in the direction (in the direction of the arrow Y1 and the direction of the arrow Y3 in order) to move the paper sheets in the feeding direction, respectively, so that the feeding roller unit 32, A bundle of paper sheets Pa (Stack) conveyed by 33 is loaded into the storage section a2. On the other hand, as shown in FIG. 8, the feed roller unit 30 rotates in the direction in which the paper sheet Pa is moved in the discharge direction (the direction of the arrow Y1), and the gate roller unit 31 maintains the stopped state, whereby the paper sheet Pa. When two or more sheets are double-fed, the multi-fed paper sheets Pa are separated and retained in the storage portion a2, and the paper sheets Pa are discharged one by one. Of course, the gate roller unit 31 may be configured to rotate in the direction in which the paper sheet Pa is moved in the loading direction when the paper sheet Pa is discharged. As shown in FIGS. 7 and 8, a paper to which a rod-like hoisting prevention member 38 such as a shaft for preventing the paper sheet Pa from being hoisted with the rotation of the feed roller unit 30 in the Y1 direction is inserted. It is the side facing the gate roller unit 31 with the leaf Pa interposed therebetween, closer to the storage portion a2 than the feed roller unit 30, and when the blade roller portions 40 and 41, which will be described later, rotate, While providing in the position which overlaps with blade | wing part 40a, 40b, 41a, 41b which a roller part has, you may comprise so that the part close | similar to the paper sheet Pa rather than the rotating shaft Cn1 of the feed roller unit 30 may be provided. The shape of the hoisting prevention member 38 is not limited to a bar shape as long as the hoisting of the paper sheet Pa can be regulated, and for example, a plate shape can be mentioned.

  As shown in FIG. 6, the pair of feed roller unit 30 and gate roller unit 31 includes comb rollers 30 a to 30 c of the feed roller unit 30 and comb rollers 31 a to 31 b of the gate roller unit 31 in the radial direction of the rotation shaft. The paper sheet Pa is sandwiched between the paper sheets Pa, and the separation function of separating and discharging the paper sheets one by one is secured by appropriately setting the overlap amount lap.

  By the way, in this embodiment, as shown in FIG. 9A, when the transaction is confirmed, the paper sheet Pa is inserted into the secondary holding unit a3 (b3, c3), and the paper sheet Pa is reciprocated until the next transaction starts. As shown in FIGS. 9 (b) and 9 (c), the reciprocating unit fo is temporarily moved upward at the beginning of the next transaction, and both ends in the width direction are moved to the reciprocating unit fo. The supported paper sheet Pa and the upper fixing plate fp fixed to the storage part a2 are brought into contact with each other, and the paper sheet Pa is slipped downward from the gap of the reciprocating movement part fo to remove the paper sheet Pa. It is stored in the storage section a2 (b2, c2), and the reciprocating movement section fo is lowered again to perform an operation for preparing the next paper sheet Pa. In this case, as shown in FIG. 9A, the fork or the like is reciprocated in a state where the input paper sheet Pa does not completely fit in the accumulation space sp (secondary holding part a3) and protrudes from the accumulation space sp. When the moving part fo is moved as shown in FIG. 9 (a) → FIG. 9 (b) → FIG. 9 (c), the paper sheet Pa may be bent at the wall surface wl constituting the storage part a2. This may cause an accumulation failure such as a jam or a feeding failure. This problem is not limited to the storage unit a2 (b2, c2) that performs the operation as in the present embodiment, but may occur in other types of storage units.

  In order to prevent this, in order to move the input paper sheet Pa to the accumulation space sp accurately and appropriately, a plurality of rotation shafts 30s of the feed roller unit 30 are provided on the rotating shaft 30s as shown in FIGS. The blade roller portions 40 and 41 are provided (the blade roller portion 41 is schematically shown in FIG. 5). The blade roller portions 40 and 41 are made of an elastic member and a plurality of flexible blade portions 40a and 40b (41a and 41b, see FIGS. 8 to 10) are radially formed along the circumferential direction. As shown in FIG. 2, the sheet roller 30 rotates together with the feed roller unit 30 about the rotation axis Cn1 of the feed roller unit 30, and the inserted paper sheet Pa is ejected to the accumulation space sp in the storage portion a2.

  As shown in FIGS. 5 and 6, a plurality of blade roller portions 40 and 41 are arranged along the rotation shaft 30s of the feed roller unit 30, that is, along the width direction of the paper sheet Pa, and the comb roller 30a. The corresponding blade portions (40a and 41a, 40b and 41b) among the blade portions (40a, 40b, 41a, 41b) of the blade roller portions 40, 41 on both sides of ˜30c are different from each other in the circumferential direction. Is arranged. Specifically, as shown in FIG. 10, when the feed roller unit is rotated 360 degrees, the relationship between the blade portion facing directly below (the paper sheet Pa side) and the rotation angle is set to a certain rotation angle of 0 degree. Explaining, the blade portion 40a faces directly below at 0 degrees, the blade portion 41a faces directly below at 90 degrees, the blade portion 40b faces directly below at 180 degrees, and the blade portion 41b faces directly below at 270 degrees. The phase relationship (40a, 40b, 41a, 41b) is defined. That is, at the same time, the plurality of blade portions do not face directly below (the paper sheet Pa side), and the pressing force that the blade roller portions 40 and 41 push the paper sheet Pa toward the gate roller unit 31 is reduced.

  As described above, the sheet processing apparatus according to the present embodiment stores and stores the storage unit a2 that stores the sheet Pa and the storage unit a2 that stores the sheet Pa (Stack). And a feed separation mechanism 3 that separates and discharges the paper sheets Pa one by one. The feed separation mechanism 3 is a feed roller unit 30 that is a pair of first roller units disposed on both sides in the thickness direction. And a gate roller unit 31 that is a second roller unit, and both roller units 30 and 31 rotate in the direction (Y1 direction, Y3 direction) to move the paper sheet Pa in the loading direction, respectively. While feeding Pa, the feed roller unit 30 as the first roller unit rotates in the direction (Y2 direction) to move the paper sheet Pa in the discharge direction, and the gate roller as the second roller unit. The elastic unit for ejecting the inserted paper sheets Pa to the accumulation space sp in the storage part a2 is configured to separate and discharge the paper sheets Pa one by one by stopping the unit 31. The feed roller unit 30 which is a first roller unit around the rotation axis Cn3 of the feed roller unit 30 which is a first roller unit is a blade roller portion 40, 41 having blade portions (40a, 40b, 41a, 41b) made of And is rotatably provided.

  If comprised in this way, the feed roller which has the blade | wing part 40,41 which has the blade | wing part (40a, 40b, 41a, 41b) which consists of an elastic member at the time of insertion of the paper sheet Pa will move the paper sheet Pa in the insertion direction. The paper sheet Pa inserted by rotating around the coaxial Cn1 together with the unit 30 is ejected to the accumulation space sp in the storage unit a2, and the paper sheet Pa is appropriately input to the storage unit a2, while the paper sheet Pa Since the blade roller portions 40 and 41 rotate around the coaxial Cn1 together with the feed roller unit 30 that moves the paper sheet Pa in the discharge direction when the paper is discharged, the blade roller portions 40 and 41 do not obstruct the path of the paper sheet Pa. Further, it becomes possible to prevent defective discharge of the paper sheet Pa such as misfeed due to the interference between the paper sheet Pa and the blade roller portions 40 and 41. Moreover, since the blade roller portions 40 and 41 do not obstruct the path of the paper sheet Pa, the blade portions (40a, 40b, 41a, 41b) of the blade roller portions 40, 41 are used in order to reduce discharge defects caused by the path obstruction. It is no longer necessary to reduce the number of blades or reduce the rigidity of the blades (40a, etc.), and by reducing the number of blades (40a, etc.), retraction to the accumulation space sp is not in time, and jamming and other defective accumulation occurs. This prevents the blade roller sections 40 and 41 from reducing the force with which the paper sheet Pa is expelled into the accumulation space sp, and allows the paper sheet Pa to be accurately put into the storage section a2. .

  Particularly, in the present embodiment, the gate roller unit 31 is stopped when the paper sheet Pa is discharged, and the blade roller units 40 and 41 are provided in the feed roller unit 30 instead of the gate roller unit 31. There is no need to provide a complicated mechanism for positioning and controlling the gate roller unit 31 in such a posture that the blade roller sections 40 and 41 do not obstruct the path of the paper sheet Pa when the paper sheet Pa is discharged. Thus, it is possible to realize the apparatus with a simple configuration while reducing the size of the apparatus and reducing the manufacturing cost. In this case, since the gate roller unit 31 can be stopped in an arbitrary rotational posture, the comb rollers 31a to 31b of the gate roller unit 31 are locally worn by always stopping the gate roller unit 31 in a constant posture. It is possible to prevent uneven wear and to prevent a reduction in separation function due to uneven wear.

  Furthermore, in this embodiment, since the blade roller units 40 and 41 are provided not in the gate roller unit 31 but in the feed roller unit 30, when the paper sheet Pa is discharged, the blade roller units 40 and 41 use the gate roller unit. In this embodiment, the blade roller portions 40 and 41 are disposed on the paper sheet Pa, although there is a possibility that the paper sheet Pa is pressed to some extent to 31 and a new discharge failure of the paper sheet Pa may occur due to the magnitude of the pressing force. A plurality of blade portions (40a, 40b, 41a, 41b) formed on the blade roller portions 40, 41 are arranged so that their positions in the circumferential direction are different from each other. Therefore, it is possible to reduce or eliminate the simultaneous pressing of the paper sheets Pa by the plurality of blade portions 40a and 40b, and the pressing by the blade roller portions 40 and 41 is possible. It is possible to reduce the discharge failure of the sheet Pa by reducing the force.

  In addition, in this embodiment, both roller units 30 and 31 respectively have comb rollers 30a to 30c and 31a to 31b that sandwich paper sheets Pa by overlapping each other in the radial direction, and these comb rollers 30a to 30c, Since the appropriate separation function is ensured by the overlap amount lap between 31a and 31b, the proper separation function is appropriately prevented from being damaged by uneven wear.

  As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not only by the above description of the embodiments but also by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  For example, in the present embodiment, the blade portions (40a, 40b, 41a, 41b) among the plurality of blade roller portions 40, 41 are arranged so that the positions in the circumferential direction are different from each other, as shown in FIG. In addition, the corresponding blade portions (140a and 141a, 140b and 141b) among the plurality of blade roller portions 140 and 141 may be arranged so that the positions in the circumferential direction coincide with each other. If comprised in this way, since several blade | wing parts (140a and 141a, 140b and 141b) face directly below (paper sheet Pa side), the paper sheet Pa is hold | gripped in several points of the width direction, and it certainly ejects. It becomes possible.

  In addition, the feed roller unit 30 of the present embodiment is provided with a plurality of blade roller portions 40 and 41, but the number of blade roller portions provided in the first roller unit may be single.

  Furthermore, the loading / separating mechanism 3 according to the present embodiment loads the stacked paper sheets Pa into the storage unit a2, but continuously loads the sheets one by one as shown in FIG. It can be applied to the input / separation mechanism 303. In this case, in order to prevent the input paper sheets from interfering with the subsequent paper sheets, the input paper sheets are transferred to the subsequent paper sheets by the blade roller unit until the subsequent paper sheets are input. It is necessary to move to a retreat position where interference with the leaves is avoided, and in order to realize this, it is desirable that a large number of blade portions are formed in the circumferential direction on the blade roller portion. The application of the present invention is preferable in the sense that the discharge failure of the paper sheet Pa can be reduced without reducing. Needless to say, the present invention does not impede the application to a loading / separating mechanism that batch-loads stacked sheets in a storage unit as in this embodiment.

  In addition, in the present embodiment, paper sheets are conveyed using belt conveyance, but the present invention can also be applied to those that do not use belt conveyance. For example, one in which the conveyance rollers 37 shown in FIG. In this embodiment, the gate roller system is adopted as the input separation mechanism, but the present invention is not limited to this. For example, the thing using a FRR system is mentioned.
