Description

  The present invention relates to a paper sheet stacking apparatus, a paper sheet handling apparatus, and an automatic cash transaction apparatus.

  In a financial institution or the like, an automatic cash transaction apparatus is used for transactions with users such as deposits and withdrawals. This automatic teller machine includes a paper sheet handling apparatus that handles paper sheets such as banknotes and forms. And this paper sheet handling apparatus is provided with the paper sheet stacking apparatus which stacks the paper sheets conveyed from the outside. And this paper sheet handling apparatus is equipped with the accumulation | storage box for accumulating the said paper sheets.

  In such a paper sheet stacking apparatus, depending on the structure, a paper sheet already stacked in the stacking box collides with a new paper sheet subsequently carried into the stacking box, and the paper sheet stacks. In some cases, leaf breaks or paper jams occurred. Such obstacles were particularly noticeable when paper sheets with creases and curls were accumulated in the accumulation box.

  Therefore, conventionally, various techniques for suppressing the above-described failure have been proposed. For example, the following Patent Document 1 describes a paper sheet processing apparatus including a mechanism that knocks down a rear end portion of banknotes carried into a stacking unit (stacking box) with a blade plate provided around an impeller. Yes. Patent Document 2 below describes a paper sheet stacking device including a mechanism for pressing a rear end portion of paper sheets carried into a stacking unit (stacking box) with a cam. And according to these technologies, the paper sheets already loaded in the stacking box and the stacking box in the stacking box by tapping or pressing down the rear end of the paper sheets carried into the stacking box.

C2. Reject box behavior:
As described above, the recycle box 130a is controlled by the control unit 118 provided in the banknote handling apparatus 101. Hereinafter, the operation of the recycle box 130a when stacking the banknotes 10 in the stacking box 137 and the operation of the recycle box 130a when feeding the banknotes 10 from the stacking box 137 will be described.

C2.1. Operation when stacking banknotes:
FIG. 5 and FIG. 6 are explanatory diagrams showing the operation when stacking the banknotes 10 in the recycle box 130a.

  As shown in FIG. 5 (a), the banknotes 10 loaded one by one from the inlet / outlet of the banknotes 10 at the upper ends of the transport guides 131g1 and 131g2 are transported rollers 131r1, transport rollers 131r2, feed rollers 132, and pinch rollers. 133, and the feed roller 132 and the gate roller 134 are nipped, and each roller is conveyed by rotating in a direction indicated by an arrow in the drawing.

  Then, as shown in FIG. 5B, when the leading end of the banknote 10 comes into contact with the tapping member 136, the tapping member is applied by the force acting on the tapping member 136 by the rigidity of the banknote 10 and the conveying force. 136 is pushed upward. At this time, the spring 136s contracts. The state of the hitting member 136 at this time corresponds to the first state in the present invention.

  Then, the banknote 10 is continuously conveyed by the carry-in mechanism described above while pushing the hitting member 136 upward, and as shown in FIG. 6A, the banknote 10 contacts the lower surface of the stacking guide 139, Along the lower surface of the accumulation guide 139, the accumulation guide 139 is guided downward in the accumulation box 137.

  When the rear end portion of the banknote 10 is carried into the stacking box 137, the banknote 10 is stacked by the weight of the tapping member 136 and the reaction force of the spring 136s, as shown in FIG. It is knocked down in the box 137. The state of the hitting member 136 at this time corresponds to the second state in the present invention. The banknotes 10 struck by the striking member 136 are accumulated in the stacking box 137.

  In the illustrated example, there is a sufficient stacking space in the stacking box 137, and the banknote 10 already stacked in the stacking box 137 and the banknote 10 that has been subsequently carried in do not collide. Even if the banknote 10 has a relatively small stacking space, and the banknote 10 already stacked in the stacking box 137 has folds or curls, the banknote 10 is pressed downward by the tapping member 136. be able to. Therefore, it is possible to prevent a collision between the banknote 10 already accumulated in the accumulation box 137 and the banknote 10 subsequently carried in.

C2.2. Operation when bills are fed:
FIG. 7 is an explanatory diagram showing an operation when the banknote 10 is fed out in the recycle box 130a.

  As shown in the drawing, when the banknote 10 is fed out from the stacking box 137, the hitting member 136 and the stacking guide 139 are lifted above the lowermost portions of the feed roller 132 and the pickup roller 135 by an actuator (not shown). . Further, the lifting plate 137b of the stacking box 137 is lifted by the lifting mechanism described above until the banknote 10 deposited on the top of the stacking box 137 contacts the pickup roller 135 with a predetermined load. The load when the pickup roller 135 and the banknote 10 deposited at the top of the stacking box 137 come into contact with each other can be detected by providing a load sensor on the rotation shaft of the pickup roller 135, for example.

  Then, the bill 10 is rotated at the upper end of the conveyance guides 131g1 and 131g2 by rotating the pickup roller 135 in the direction of the arrow shown and rotating the feed roller 132 and the conveyance rollers 131r1 and 131r2 in the direction of the arrow shown. The banknotes 10 are unloaded one by one from the entrance / exit.

  When the uppermost banknote 10 accumulated in the stacking box 137 is unloaded, the contact load between the pickup roller 135 and the banknote 10 to be unloaded next decreases. The lifting plate 137b of the stacking box 137 is sequentially lifted by the lifting mechanism.

D. Reject box:
The configuration and operation of the reject box 140 are substantially the same as the configuration of the recycle box 130a described above and the operation when the banknotes 10 are stacked in the recycle box 130a. However, in the present embodiment, the reject box 140 does not need to pay out the reject banknotes accumulated in the accumulation box to the outside, so the pickup roller 135, the lifting plate 137b, and the lifting plate 137b in the recycling box 130a described above. Are not provided with a mechanism corresponding to the lifting mechanism (driving belt 138b, driving rollers 138a1, 138a2, rollers 138r1, 138r2, driving motors for driving the driving rollers 138a1, 138a2, etc.). The reject box 140 may have the same configuration as the recycling box 130a described above.
