Description

  The present invention relates to a banknote separator for a banknote processing machine for processing banknotes.

  In the banknote separator of the banknote processor used for ATM etc. for many unspecified persons to insert a banknote, it is necessary to be able to pay | pay out and convey a banknote stably. Generally, the banknote separator of a banknote handling machine includes a banknote insertion unit into which banknotes are inserted, and a separation transport unit that separates and transports a bundle of banknotes inserted into the banknote insertion unit. The banknote separating device is fed out from the separating mechanism section as it is even when the banknotes inserted into the banknote inserting section are disturbed. As a result, after the banknote is fed out, the banknote handling device detects the abnormal conveyance such as heavy running or skew, and then returns the taken banknote to the banknote insertion unit again. There was the trouble of setting the banknote again.

  In Patent Document 1, in a banknote depositing / dispensing machine that rotates and feeds a pool part that accumulates banknotes, a friction member is provided on a guide wall that guides the rotation of the pool part, and the pool part is rotated along the guide wall. In this case, a structure is disclosed that prevents the feeding failure caused by sticking between banknotes by separating the end face of the banknote by friction with a friction member.

  Generally, the banknote separator of a banknote processing machine is as showing in FIG.3 and FIG.4. FIG. 3 is a side view showing the structure of the banknote separator, and FIG. 4 is a plan view showing the structure of the banknote separator. The banknote separating apparatus 200 presses the movement guide 2 against the banknote 1 and rotates the feeding roller 5 disposed below the guide 4 counterclockwise in FIG. 3 (in the direction of the arrow in FIG. 3). Thus, if the banknote 1 is normal, the banknote 1 is sequentially separated from the lowermost banknote, and is fed out from the separation roller 7 and the gate roller 8 into the transport path along the transport guide 9.

  However, as shown in FIG. 3, when the bundle of inserted banknotes is set in a state where the upper banknotes are popped out from the lower banknotes, double feeding as shown in FIG. 3 occurs. That is, the banknote on the upper side of the lowermost banknote is fed out first, and the lowermost banknote is also fed out so as to be dragged by this, resulting in double feeding.

  Moreover, as shown in FIG. 4, when the banknote 1 is set in a state tilted left and right, one side of the banknote 1 as shown in FIG. 4 is quickly clamped to the separation roller 7, and the inclination of the banknote 1 is increased. When taken into the conveyance path, it is conveyed in a skewed state.

  Patent Document 1 discloses a structure that prevents a feeding failure due to sticking between bills by using a friction member to separate the end faces of the bills by friction. However, even if a bundle of banknotes in the banknote pool is disturbed immediately before the banknotes are fed out, there is no mechanism for aligning them. For this reason, the abnormal transport such as heavy running and skew shown in FIGS. 3 and 4 is likely to occur.

  Further, Patent Document 2 is not a banknote separator of a banknote processing machine, but in the paper sheet stacking mechanism, when sequentially stacking paper sheets sequentially transported from the transport path into the stacking chamber, A method of orderly collecting paper sheets in an aligned state is disclosed. That is, a collecting lever is provided in the stacking chamber, and the end surfaces of the paper sheets are hit and aligned. At this time, the assembling lever has a structure in which a flat plate for hitting paper sheets is incorporated into a spring mechanism via an arm, and the end faces of the paper sheets are hit and aligned by a reciprocating motion using a spring. That is, a special mechanism for reciprocating the lever is required. Furthermore, the method of Patent Document 2 is unstable due to the fatigue of the spring and the fatigue and deformation caused by the reciprocating motion of only one lever.

  Since Patent Document 2 is a mechanism for orderly stacking paper sheets in an aligned state, the stacked paper sheets are not subsequently transported. Therefore, when hitting and aligning the end faces of paper sheets, even if they are prone to malfunction and are unstable, it is not a problem. However, when a process such as conveyance is involved after the accumulation, an unstable mechanism that easily causes malfunction is a big problem.

  The present invention has been made in view of the circumstances as described above. The purpose of the present invention is to separate banknotes of a banknote processing machine used for ATMs and the like for an unspecified number of people to insert banknotes. In the apparatus, it is to realize a banknote separating apparatus that is unlikely to cause abnormalities such as heavy running and skewing in the conveyance of banknotes and that can stably perform the banknote conveyance operation over a long period of time.

  A banknote insertion unit that inserts banknotes from a banknote insertion port, a banknote alignment unit that aligns the banknotes that are input from the banknote insertion port to the banknote insertion unit, and a separation transport unit that feeds the banknotes aligned by the alignment unit; The banknote aligning section includes an alignment roller having a rotating body and an alignment plate arranged in an impeller shape on a peripheral surface of the rotating body, and the alignment plate is moved by rotating the alignment roller. The banknotes are aligned by pressing against an edge.

  According to the present invention, in the banknote separator of a banknote processor used for ATMs and the like for an unspecified number of people to insert banknotes, the end face of the banknotes taken into the banknote insertion part is immediately before the banknotes are fed out. Therefore, it is possible to realize a banknote separating apparatus that is unlikely to cause abnormalities such as heavy running and skewing in banknote transport and that can stably transport banknotes over a long period of time.
