Step S21: the processing controls portion 110 notice master control part 11 of depositing and withdrawing have been interrupted the situation that deposit is handled owing to returning unusual bank note.Master control part 11 utilizes display control unit 14 to show to operator's inquiry whether be ready to proceed the deposit processing on not shown read out instrument, and receives operators' (client) affirmation operation from operating portion 13.Deposit and withdraw processing controls portion 110 from the notice of master control part 11 receptions about the result of affirmation operation, if the words of YES advance to step S22.Deposit and withdraw processing controls portion 110 from the notice of master control part 11 receptions about the result of affirmation operation, if the words of NO advance to step S23.
Step S22: after the processing controls portion 110 that deposits and withdraws confirms that continuation is deposited processing to normal bank note, advance to step S12 once more.
Step S23: deposit and withdraw processing controls portion 110 after bank note is moved to the portion of depositing and withdrawing 120 from a reserve part 160, open the flashboard of the portion of depositing and withdrawing 120, return unusual bank note, finish deposit and handle.
Therefore, the deposit processing time becomes wait time for the operator.And took in deposit bank note in waiting time reserve part 160, therefore can be rapidly and take in processing reliably.
Then, the deposit reheat treatment that the processing controls portion 110 that deposits and withdraws of the handling part 100 of depositing and withdrawing is carried out describes.Fig. 5 is the diagram of circuit of deposit reheat treatment.The deposit reheat treatment begins after the operator confirms amount deposited.
Step S31: the processing controls portion 110 that deposits and withdraws will be accommodated in the bank note in the reserve part 160 and move to the portion of producing 161.
Step S32: the processing controls portion 110 that deposits and withdraws produces the bank note of a reserve part 160 one by one.
Step S33: the processing controls portion 110 that deposits and withdraws judges whether the bank note that is produced can circulate.So-called circulation is meant the bank note that will be deposited in the bank note use when withdrawing the money.Judge by the judgment standard of certificate kind, appointment such as stained whether the bank note that is produced can circulate.Then, the processing controls portion 110 that deposits and withdraws judges the bank note that is produced and can be used in on-cycle words, it is transported in the pairing Currency Type box (among collecting storage facility 170a~170f some) takes in (step S34) via transporting path 140b.On the other hand, the processing controls portion 110 that deposits and withdraws judges the bank note that produced can not the on-cycle words, it is transported among main discarded storehouse 150a or the secondary discarded storehouse 150b takes in (step S35) via transporting path 140b, 140c.
Deposit and withdraw in bank note containing that processing controls portion 110 will be deposited in some, thereby finish the deposit reheat treatment in collecting storage facility 170a to collecting storage facility 170f, among main discarded storehouse 150a and the secondary discarded storehouse 150b.Then, the processing controls portion 110 that deposits and withdraws will deposit the advisory master control part 11 that reheat treatment finishes.The notice that master control part 11 reception deposit reheat treatments finish, going forward side by side worked provides with bar with by processing such as card handling part 17 discharge cards with bar granting portion 18.
Then, withdrawn the money to handle and describe what the processing controls portion 110 that deposits and withdraws of the handling part 100 of depositing and withdrawing carried out.Fig. 6 is the diagram of circuit of withdrawing the money and handling.Withdraw the money to handle and begin based on the withdrawing the money indication of operator.
Step S41: deposit and withdraw processing controls portion 110 via transport path 140c with bank note from Currency Type box (collecting storage facility 170a~170f) be transported to the discriminating portion 180.
Step S42: the processing controls portion 110 that deposits and withdraws utilizes the true and false of discriminating portion 180 identification notes, is differentiating to being with bank note containing (step S43) in the portion of depositing and withdrawing 120 under the situation of normal bank note.On the other hand, the processing controls portion 110 that deposits and withdraws utilizes the true and false of discriminating portion 180 identification notes, do not differentiated to being that (being under the situation of unknown bank note) and is used to bank note containing (step S46) in the discarded storehouse withdraw the money with other bank note and advances to step S41 under the situation of normal bank note.
Step S44: the processing controls portion 110 that deposits and withdraws opens the flashboard of the portion of depositing and withdrawing 120.
Step S45: the processing controls portion 110 that deposits and withdraws waits for that bank note is removed.Then, the processing controls portion 110 that deposits and withdraws closes flashboard after bank note is removed detecting from the portion of depositing and withdrawing 120, finishes to withdraw the money processing.On the other hand, the processing controls portion 110 that deposits and withdraws does not detect in the given time and closes flashboard when bank note is removed and regain bank note (step S47) from the portion of depositing and withdrawing 120, finishes to withdraw the money processing.
Fig. 7 is the sectional view that the structure of the described bank note conveyer of embodiment is shown.
This bank note conveyer has the distributor gears that adopts in above-mentioned automatic trading apparatus 1.This bank note conveyer is characterised in that, employing has the swivel (for example with the flat tyre wheel with impeller 21 22 shown in the long and short dash line) of and the jut that with scraps of paper class contact outstanding from side face, and does not adopt the 3rd in the existing apparatus shown in Figure 14 to transport driven roller 232.
For other structures, be marked with the identical symbol of counterpart in the existing apparatus with Figure 14, and omit repeat specification.
On this flat tyre wheel 22, append the impeller coaxial 21 with it, and with distributing gate 201,203 to constitute distributor gears.And, can apply transport force to passing the bank note of coming by this impeller 21 from branch point, therefore need not the driven roller that is disposed at the distributor gears downstream (pinch roll 202,204,205 for example shown in Figure 14 etc.) in the past.Therefore, using belt conveyor or transfer roller to transport at high speed in the scraps of paper class conveyer of scraps of paper class such as bank note, having transporting branch point and being used to switch under the situation of distributor gears (distributing gate mechanism or valve system) of carriage direction of the destination that is used to change every bank note, transport even also can stably carry out branch for the bank note also shorter than common specification.
Fig. 8 is the figure that the planar structure of the described bank note conveyer of embodiment is shown.
Wherein, showing bank note M with birds-eye view begins along the structure of transporting the path that moves abreast with its short side direction from the right-hand side of Fig. 8.Transport in the path at this, the upstream portion of driven shaft 26 and downstream part become transports branch point.
This driven shaft 26 transports the branch point place by what its left and right sides support F1, F2 remained on guide portion.On driven shaft 26, be provided with the guiding belt wheel of flat tyre wheel 22a~22d as guiding moving belt 23a~23d.In addition, on each flat tyre wheel 22a~22d, has the impeller 21 that rotates coaxially with them.
Be equivalent to moving belt shown in Figure 7 231 with four moving belt 23a~23d shown in two long and short dash lines.In addition, on the flat tyre wheel 22a~22d of driven shaft 26, similarly set up described moving belt 23a~23d with the driven shaft 26 of existing apparatus shown in Figure 16.
Turning cylinder 20a, the 20b parallel with driven shaft 26 are kept by left and right sides support F1, F2 respectively in the front and back of driven shaft 26.On described turning cylinder 20a, 20b, similarly dispose distribution gate 203 shown in Figure 7 respectively and distribute gate 201.
Distribute gate 203 to deposit under the situation of bank note M, perhaps, switch the bank note direction of transfer taking out from the portion of depositing and withdrawing under the situation of bank note M in the graphic portion of depositing and withdrawing never.In addition, distribute gate 201 to switch in the mode of distinguishing the bank note that has deposited in that transports by the bank note that takes out in the collecting storage facility with to discriminating portion.
Fig. 9 is the front view of driven shaft that the axle bearing guiding belt wheel of the described bank note conveyer of embodiment is shown.
Central portion at flat tyre wheel 22a~22d is provided with the groove narrower than the width of moving belt (central slot part), and each impeller 21 is configured to can be received in the central slot part of flat tyre wheel 22a~22d.Thus, it is different that the axle bearing in the existing apparatus of driven shaft 26 and Figure 16 transports the axle 25 of driven roller, need not four driven roller 22a~22d.
Like this, dispose under the situation of gate mechanism bank note M that is transported and impeller 21 butts that are integrally formed on flat tyre wheel 22a~22d in the front and back of the guiding belt wheel that transports the branch point place.Thus, can shorten the distributor gears downstream no transport force transport the path part, even also can eliminate this part.Therefore, can not take place because of being transported situation about stopping than the short scraps of paper class of distance till from the branch point of bank note conveyer to transfer roller.
Figure 10 is the sectional view that is illustrated in the bank note conveyer among the Fig. 7 that has switched under the state behind the carriage direction.Wherein, distribute gate 201 to switch to the position of leaving flat tyre wheel 22.And, distribute gate 203 to switch to the position of leaving the 4th guide portion 240.
Thus, as shown in figure 10, by 220 guiding of second guide portion and be transported to flat tyre wheel 22, then distributing gate 201 to switch and be transported to the 4th guide portion 240 with impeller 21 from the taking-up bank note of collecting storage facility.At this moment, flat tyre wheel 22 and impeller 21 be together along the right-hand revolution in the shown position, therefore is sandwiched under the state between second guide portion 220 and the 3rd guide portion 230 and applies predetermined propulsive effort to transporting bank note transporting bank note.
Figure 11 shows the figure of the side view of the impeller shown in Fig. 9, the state when (A) figure is static, the state when (B) figure is rotation.
Impeller 21 with four 21a of foot is formed by rubber-like material formings such as for example poly-urethane rubbers.The mode that impeller 21 when static is accommodated in four 21a of foot in the central slot part of flat tyre wheel 22 keeps.
Impeller 21 is configured to and can rotates simultaneously around driven shaft 26 and flat tyre wheel 22.Therefore, the 21a of foot of impeller 21 shown in Figure 11 (B) around driven shaft 26 during to right-hand revolution, can because of centnifugal force to the peripheral direction expansion, and project to respectively and be subjected to the guide surface 23 that moving belt 231 and guide portion 240 etc. are limited.At this moment, a plurality of by on the outside face of each 21a of foot, forming (shown in the figure 3) groove 21b, and transport and produce boundary effect (edge effect) between the bank note, and by having thick and heavy 21c at its front end, thereby can easily utilize centnifugal force to expand to peripheral direction.
The impeller 21 of this shape constitutes each 21a of foot can be outstanding from the outer peripheral face of flat tyre wheel 22, and each 21a of foot of impeller 21 is in the state that is surrounded by flat tyre wheel 22 mostly when static.Therefore, can be reduced in bank note breakage etc. significantly and when jam took place, staff's mistake was broken the 21a of foot of impeller 21 off with the fingers and thumb disconnected risk.
In addition, for the bank note along the side face branch of flat tyre wheel 22a~22d, impeller 21 is in the in-to-in state that is folded in flat tyre wheel 22a~22d, impeller 21 easily and the bank note of branch point be close to.Therefore, eliminate no transport force interval in the front and back of distributor gears, and will transport the sound that produces in the process of scraps of paper class and also suppress lessly, realized quiet and stable impeller 21.
Figure 12 shows the figure of the swivel with jut different with impeller shape, and (A) figure is the shape of jut when being absorbed in, and (B) figure is the shape that jut expands to guide surface.
Swivel 24 is formed with four jut 24a on its outer peripheral face.In addition, be formed with four blank part 24h at jut 24a with for the centre of the chimeric fitting portion (core) of driven shaft 26.
This swivel 24 with only can be different to the impeller 21 of direction rotation, it can be to positive and negative twocouese rotation.That is, the jut 24a of swivel 24 does the time spent in the external force that is subjected to from moving belt 23a and the 4th guide portion 240 etc., is trapped in shown in Figure 12 (A) in the central slot part of flat tyre wheel 22.Under the state that is not subjected to the external force effect, the jut 24a of swivel 24 projects to the guide surface 23 that is limited by guide portion 240 grades.Therefore, swivel 24 also can transport bank note when flat tyre wheel 22 contrarotations.In addition, listed the situation that on the outer peripheral face of swivel 24, is provided with four jut 24a at this, however also can according to the elastic force of swivel 24, with the relation of the rotative speed of swivel, determine suitable number.
Figure 13 is the figure that the belt wheel with crown shape that uses as the guiding belt wheel of Fig. 9 is shown.
It is higher that the face of joint of flat tyre wheel 22 and moving belt 23a constitutes the central slot part that disposes impeller 21, and be formed with the dip plane of angle [alpha] (about 10 °) towards the left and right side.Thus, flat tyre wheel 22 contacts with the middle body of the circumferential speed maximum of moving belt 23a on the peripheral part of the flat tyre wheel 22 of this rotation.Therefore, the impeller 21 of being located at the central slot part of flat tyre wheel 22 can not hinder moving belt 23a to advance.
