Description

  The present invention is configured inside an automatic transaction apparatus that handles paper sheets such as banknotes, and feeds paper sheets accumulated in a stacking unit by a payout process such as dispensing one by one from the stacking unit to a conveyance path. More particularly, the present invention relates to a paper sheet feeding device suitable for feeding various types of paper sheets having different width sizes in the transport direction.

  As a feeding mechanism of a conventional paper sheet feeding device, there is one that is configured by a pick roller, a feed roller, a gate roller, and the like and that feeds bills having different short lengths in a vertically downward direction. Since these paper sheet feeding devices are provided with a configuration in which the bottom part of the stacking unit is inclined even in banknotes having different short lengths, the paper sheet feeding apparatus utilizes the fact that the banknotes are aligned on one side by gravity. It pays out after aligning the bill edges.

  As a device for feeding from the upper side of banknotes stacked in the horizontal direction and providing a protrusion that contacts the banknote to prevent skewing during feeding, there is one disclosed in Patent Document 1. This feeding device has a guide for guiding paper sheets to be conveyed into the apparatus when stacking paper sheets, and is a single-sheet paper stacking type paper sheet that separates one sheet from the same mouth as during stacking. An apparatus for separating and accumulating the guide, and the guide that reaches when the paper sheet to be transported and the transported paper sheet are completely accumulated on the surface of the guide that contacts the paper sheet The sheet in the conveyance direction of the surface that the paper sheet of the guide contacts rather than the straight line connecting the tips of the guide is provided with a protrusion, and the paper sheet having a fold is also effectively suppressed by the fold. It is possible to stably feed out and to reduce skew during feeding.

Japanese Unexamined Patent Publication No. 2006-21860

  In the paper sheet feeding device of the above-mentioned Patent Document 1, paper sheets having different short lengths are mixed or only short paper length is fed out from the lower side of the stacking unit in the horizontal direction with respect to the stacking direction. Mechanism. In such a configuration, a short paper sheet has a large distance between the feeding opening and the paper sheet, and the paper sheet is inclined between the feeding opening due to frictional resistance due to the weight of the paper. There was a problem of going to the line.

  Furthermore, the mechanism of the banknotes piled horizontally like the structure of the said patent document 1 is a paying-out system from the upper side, and when it pays out from the lower side of a stacking part, the friction with a floor surface is not considered. For this reason, the frictional force is increased by the gravity of the accumulated paper sheets, and the paper sheets may be fed out while being skewed. Moreover, it is not assumed that banknotes of different sizes will be fed out, and there is a risk that paper sheets will be fed out skewed.

  An object of the present invention is to stably feed out paper sheets without tilting when feeding paper sheets having a shorter short length than the banknote while storing paper sheets having a shorter short length. An object of the present invention is to provide a paper sheet feeding device that can handle the above.

  In order to achieve the above object, according to the present invention, when a paper sheet is fed out from the storage unit, the pressing plate presses the paper sheet stored in the storage unit, and the pickup roller is pressed by the pressing plate. A paper sheet holder that contacts the same surface as the surface on which the pickup roller contacts the paper sheet that is fed out and picked up by the pickup roller is rearward with respect to the feeding direction of the paper sheet that is fed out. A configuration that touches the position is adopted.

  According to the present invention, it is possible to provide a feeding and accumulating device that can feed out paper sheets without skewing even when paper sheets of different sizes are fed simultaneously or individually from the same stacking unit.

  In the present embodiment, a paper sheet feeding device (also referred to as a paper sheet handling device) provided in an automatic transaction device such as an ATM (Automated Teller Machine) employed in a financial institution system such as a bank system. Then, the paper sheet handling apparatus which processes paper sheets, such as a banknote, is demonstrated as an example.

  An embodiment of the present invention will be described in detail with reference to the drawings. Here, banknotes were used as an example of paper sheets. Next, the paper sheet handling apparatus 101 that handles banknotes will be described.

  FIG. 1 is a diagram illustrating an internal configuration of the paper sheet handling apparatus 101. In FIG. 1, a bill handling apparatus 101 is a temporary storage that stores a deposited bill until a transaction is completed, and a deposit / withdrawal port 102 where a user inserts and removes a bill, a bill discriminating unit 103 that discriminates a bill. It comprises a holding box 104, a depositing / dispensing reflux box 105 for storing banknotes for which a deposit transaction has been established, a banknote transport path 107 for transporting banknotes to each unit, and a control unit 106 for monitoring and controlling each unit. The

  Deposited banknotes inserted into the deposit / withdrawal slot 102 by the user are fed one by one to the banknote transport path 107, and the withdrawal banknotes transported from the banknote transport path 107 are accumulated at the deposit / withdrawal slot 102 to be used by the user. Receive. The bill discriminating unit 103 measures the magnetic characteristics of the bills conveyed by the bill conveyance path 107, and discriminates the denomination, authenticity, and the like of the conveyed bills. The temporary storage 104 is a part for temporarily storing the conveyed banknotes, for example, temporarily storing the banknotes deposited by the user, and storing it in the return box 105 if the user approves the transaction, The banknote is conveyed to the deposit / withdrawal port 102 and returned to the customer.

  Although not shown in detail, the banknote transport path 107 includes a belt and a roller installed so as to sandwich the banknote, and a drive motor that drives the belt and the roller. In addition, a bank path switching gate driven by an electromagnetic solenoid is provided at a branch point of the banknote transport path 107, and the banknote transport direction can be switched. Therefore, by rotating the drive motor for each transaction operation and switching the switching gate, the banknote passes through the banknote identification unit 103 and is conveyed between the deposit / withdrawal port 102, the temporary storage box 104, and the reflux box 105. The

  The control unit 106 is connected to an actuator or a sensor such as a drive motor or an electromagnetic solenoid of each unit, and controls the actuator while monitoring the state of the sensor according to a transaction. Further, it is connected to a higher-level main body control unit (not shown), controls the paper sheet handling device 101 according to a command from the main body control unit, and reports the state of the paper sheet handling device 101 to the main body control unit.

  Next, the payout structure of the deposit / withdrawal port 102 will be described.

  FIG. 3 is a diagram showing a state when the deposit / withdrawal port 102 is accumulated, and FIG. 4 is a diagram showing a state when the deposit / withdrawal port 102 is fed out.

  3 and 4, the stacking and feeding mechanism of the deposit / withdrawal port 102 includes a pickup roller 303, a feed roller 301, a gate roller 302 and a lift 307, a bucket 310 serving as a storage unit for storing banknotes, and a bucket 310 rotating ( And a pressing plate 305 having a spring-type drive opposite thereto, a sheet roller 306, sensors 308, and the like.

  The pickup roller 303 is composed of a high friction member such as rubber on the entire circumference, and the feed roller 301 is composed of a high friction member such as rubber on a part of the outer periphery.The pickup roller 303 and the feed roller 301 are rotated. Driven by a forward / reverse motor (stepping motor) (not shown), the bill is fed out. After the banknote is transported from the initial position in this way, the feed roller 301 driven by a forward / reverse rotation motor (stepping motor) (not shown) transports the banknote by applying a frictional force at a constant cycle. The feed roller 301 and the gate roller 302 are installed to face each other, and have an overlap structure (hereinafter referred to as an overlap portion) in which the opposite roller is inserted between the one roller. The gate roller 302 has a structure in which it cannot rotate in the bill feeding direction, and prevents double conveyance such as a two-sheet stack.

  With the above structure, the following operations are performed during integration and during delivery.

  First, the operation during integration will be described with reference to FIG.

  As shown in FIG. 3, the pressing plate 305 is configured so as not to interfere with paper sheets discharged into the accumulation space by moving above the accumulation space of the deposit / withdrawal port 102. The banknotes to be stacked are discharged to the stacking space by the sheet roller 306. At this time, the banknotes are thrown out along the guides so that they do not easily interfere with the banknotes already deposited. The banknote thrown into the accumulation space collides with the lift 307 and stops. The trailing edge of the bill is knocked downward by the sheet roller 306 that is rotating at the same time. As described above, the bills being conveyed are accumulated in the deposit / withdrawal port 102.

  Next, the operation at the time of feeding the banknotes inserted into the deposit / withdrawal port 102 will be described with reference to FIGS.

  The deposit / withdrawal port 102 waits for a bill to be inserted by the user in the state of FIG. After the bill insertion is detected, the bucket 310 of the deposit / withdrawal port 102 rotates using the rotational force of a forward / reverse rotation motor (not shown) as a driving force. Simultaneously with the rotation, the pressing plate 305 compresses the inserted banknote with a predetermined pressure, and enters the state of the feeding mode shown in FIG. At this time, when the pickup roller 303 is rotated, the bill is fed to the overlap portion by the high friction portion of the pickup roller 303 and the frictional force of the bill. At this time, since the lowermost banknote and the subsequent banknote have a frictional force between the banknotes, the subsequent banknote may be brought to the lowermost banknote and reach the overlapped portion in an overlapping state. Moreover, since the banknote in the lowest end is paid out, the frictional force generated by the contact between the banknote and the banknote causes a skew of the banknote. In addition, by inserting a small-size banknote into a space in which a larger-size banknote can be stored, the conveyance distance of the pickup roller 303 becomes longer, and the banknote tends to be skewed.

  Next, the structure in which the banknote transport mechanism part of the deposit / withdrawal port 102 has the banknote holding member 401 will be described with reference to FIG.

  FIG. 4 is a view showing a structure in which the bill transport mechanism portion of the deposit / withdrawal port 102 has a bill holding member 401. Since the banknote transport mechanism portion of the deposit / withdrawal port 102 has the banknote holding member 401, for example, when the banknote is largely skewed, the banknote is not correctly identified in the discrimination of the banknote, or by skewing Obstacles relating to banknote conveyance such as banknote jams during conveyance can be reduced.

  The deposit / withdrawal port 102 waits for the bill insertion in the state of FIG. 2, and after the bill insertion is detected, the bucket 310 rotates and shifts to the payout mode shown in FIG. At this time, since a pressing force is applied by the spring-type pressing plate 305 having a backlash, the banknote holding member 401 serving as a protrusion comes into contact with the banknote and compresses only the rear end of the banknote. In the present embodiment, the banknote holding member 401 has been described as a protrusion provided on the bottom of the bucket 310. However, the banknote holding member 401 may be formed of a member other than the protrusion, and may be fed out by a pressing plate or the weight of the superimposed banknote itself. When pressing from the upper surface of the banknote, a member capable of applying a force to the banknote to maintain the current position of the banknote by frictional force or the like against the surface (lower surface) opposite to the side where the banknote is pressed If it is good.

  When the banknotes stored in the bucket 310 are started to be fed, the rotational force is held by the frictional force between the banknotes and the banknote holding member 401 to prevent the banknotes from skewing. When the banknote is pulled to a certain extent, the contact with the banknote holding member 401 is released, and the banknote is drawn out to the overlap portion. Further, the timing at which the pick-up roller 303 starts rotating is preliminarily fed earlier by appropriate control than the timing at which the feed roller 301 wraps on the gate roller 302, so that the banknote reaches the time when the bill reaches the overlap portion. Is skewed, the skewed banknote can be corrected by the resistance of the overlap portion and the conveying force generated by the pickup roller 303 rotating.

  Here, the correction of the skew of the bill by the control method of the pickup roller 303 and the feed roller 301 will be described with reference to FIGS. 5 and 6 are views of the deposit / withdrawal port 102 as seen from above.

  The bills preliminarily fed when the pickup roller 303 starts to move quickly by appropriate control generate time for staying at the overlap portion. In the state of FIG. 6, the pick-up roller 303 continues to rotate, and the rear end of the bill that is skewed and delayed is conveyed. Since the leading side does not move until the partial rubber of the feed roller 301 rotates, the skew of the banknote is corrected (FIG. 6 → FIG. 5).

  In the present embodiment, banknotes are used as paper sheets, and a banknote feeding apparatus has been described as a device for handling the banknotes. However, as paper sheets, gift certificates, paper, and even printed paper and weak rigidity are used. It may be made of a plastic material such as a polymer, and can be applied to any processing apparatus having a structure in which those paper sheets are stacked in a stacking portion. Further, in the present embodiment, the case where the widths of the paper sheets in the short direction are different as the sizes of the paper sheets has been described. For example, the feeding direction from the feeding unit is the longitudinal direction of the paper sheets. In this case, it is a technique that can also be applied to a case where banknotes with different widths in the longitudinal direction are mixed and accumulated.

  In addition, the stacking method is not limited to a form in which paper sheets of different sizes are mixed and stacked, but may be a case in which different sizes are separately fed from the same size feeding unit. Furthermore, the sensor which can detect a banknote with a short banknote size is provided inside the stacking unit, and the banknote bundle holding member 401 may be protruded from the bottom of the bucket 310 when a banknote with a short size is fed out. In this embodiment, the structure of the feed roller 301 has been described as an example in which a high friction member is provided on a part of the outer periphery of the roller. A structure having no friction member may be used as long as the bill is guided to the feeding side by a dynamic friction force generated when the outer periphery of the roller and the bill come into contact with each other.

  In a feeding device that feeds from the underside of the inserted bill, a pickup roller 303, a feed roller 301, a gate roller 302, a bucket 304 that rotates to become a floor 304, a pressing plate 305 opposite to the surface 304, paper Equipped with a banknote bundle holding member 401 that resists the conveying force of the paper sheet when the paper sheet is fed out, and stable without skew even if the short length of the paper sheet to be processed is different Can be paid out.
