Background technology
Automatic media dispenser is the device of a kind of medium that is used to handle economically valuable (such as, banknote).This automatic media dispenser is installed in bank, public office (publicoffice), school etc. to handle various media.For example banknote, check, ticket, certificate etc. represented in the term " medium " that this paper uses.Medium comprises compares the various objects with very little thickness with its width or length.
Below the internal structure of automatic media dispenser is briefly described.Automatic media dispenser is provided with and deposits in/extraction unit, and the client can deposit in through this/and extraction unit deposits or extracts medium in.And, provide the medium delivery unit to be used for transmitting to deposit in/medium of extraction unit, and in diagnosis unit to discerning through the type and size of the medium of medium delivery unit etc.To in diagnosis unit, return to the client through the medium delivery unit by detected unusual medium, and perhaps be sent to and reclaim the unit and be kept at wherein.
Simultaneously, normal medium passes through the medium delivery unit once more, is kept at temporarily then to stack in the unit temporarily.According to requirement of client, be kept at the medium that temporarily stacks the unit temporarily and discharged once more, be stored in the medium memory cell then.As stated, in automatic media dispenser, the media stacking device is responsible for stacking deposit the medium that stacks in the unit and extract from the medium memory cell in temporarily.
Yet above-mentioned correlation technique has following problem.
Medium is introduced into then and is stacked unit and medium memory cell temporarily by transmission such as input rollers.Introduce the inwall collision that stacks the front end of the medium in unit and the medium memory cell temporarily and stack unit and medium memory cell temporarily by the turning effort of above-mentioned input roller.At this moment, under the situation of the impact energy that has big medium, the front end of medium possibly be folded or be crooked and impaired.If medium is impaired as described above, then there is such problem, promptly medium can't be overlayed equably and stacked in unit and the medium memory cell temporarily.
As an example of medium, below will be to describing at the banknote of Korea S's circulation.In the banknote (old banknote) that Korea S uses at present, 10,000 circle banknotes have about 76 centimetres width.Yet, issued the new banknote of width recently less than old banknote, so new banknote just circulates with old banknote.In new banknote, 10,000 circle banknotes have about 68 centimetres width.
Because above-mentioned media stacking device is on the basis of old banknote, to make, therefore there is such problem, promptly under the situation of introducing new banknote, be difficult to stack equably banknote.That is to say that when between old banknote, inserting new banknote, new banknote maybe quilt be stacked in that vertical and horizontal are unjustified.Except the above new banknote of describing as an example, the banknote with foreign currency of relative reduced size can not be stacked equably, thereby when discharging banknote, can occur mixed and disorderly.
Particularly, if there is crooked phenomenon, promptly banknote is exceedingly unjustified and by being stacked, then when discharging banknote, possibly occur in a jumble.As stated, under the situation of the banknote of introducing different size, because banknote has different length, so banknote vertically do not stacked equably, thereby when discharging banknote, possibly occur mixed and disorderly.

The specific embodiment
Hereinafter, will describe in detail according to the medium shock absorber of automatic media dispenser of the present invention and preferred implementation with reference to accompanying drawing with media stacking apparatus of this device.
Fig. 1 shows the lateral plan according to the preferred implementation of the media stacking apparatus of automatic media dispenser of the present invention, and Fig. 2 shows the guide wire of alternative shape that stacks band of embodiment of the present invention.
With reference to accompanying drawing, framework 10 defines the outward appearance of media stacking apparatus.For the internal structure of illustrated frame 10, the part of framework 10 only shown in the drawings, other part can be separately positioned on the both sides of framework 10 shown in the drawings.Framework 10 forms and is the shape that is essentially rectangular hexahedron and defines external frame.
In framework 10, define the predetermined space 12 that stacks, thus medium
mCan be overlayed wherein.Stack space 12 and have the rectangular hexahedron shape substantially, the stay bearing plate of describing subsequently 22 is installed in and stacks in the space 12 so that can move up and down.
Input roller 14 is installed in the framework 10.Input roller 14 be installed in rotation on the input roll shaft 14 that is arranged in the framework 10 ' on.Input roller 14 is arranged on the entrance, and medium is introduced into through this inlet.Input roller 14 allows medium
mSurface and input roller 14 closed contacts, and allow medium
mBe introduced into and stack in the space 12.Power through being transmitted by from the independent drive source (not shown) that is installed in framework 10 outsides to input roller 14 supplies drives input roller 14.Obviously, propulsion source can be installed in the framework 10.
In addition, thin plate roller 16 is installed in the below of input roller 14.Similar with input roller 14, thin plate roller 16 be installed in rotation on the thin plate roll shaft 16 that is arranged in the framework 10 ' on.Thin plate roller 16 and input roller 14 combineds action are to allow medium
mBe introduced into and stack in the space 12.
A plurality of blades 18 that thin plate roll shaft 16 ' have is provided with on its outer peripheral face twist.The effect of blade 18 is to knock medium downwards
mUpper surface, thereby the medium of introducing by input roller 14
mCan be overlayed on the stay bearing plate 22 equably.
Adapter plate 20 is installed in the top of framework 10.Adapter plate 20 is installed on framework 10 regularly and plays such effect, promptly works as medium
mPrevent medium when being introduced in the framework
mUpwards leave.
In addition, stay bearing plate 22 is installed in the bottom of framework 10 so that can move up and down.Stay bearing plate 22 is the media that are introduced into
mBasically be stacked in the part on it.Stay bearing plate 22 is installed into and can moves with respect to adapter plate 22.
Particularly, if medium is introduced in indication
mSignal be issued, then stay bearing plate 22 moves so that separated by a distance with adapter plate 20.And the distance between stay bearing plate 22 and the adapter plate 20 is configured to be high enough to feasible when the medium that is introduced into
mOverlayed stay bearing plate 22 last time medium
mExceedingly rotate.Under this initial condition, according to the medium that is introduced into framework
mQuantity, stay bearing plate 22 moves down so that allow medium
mFirmly stacked.
Simultaneously, driven roller 30 be installed in rotation on the drive roller shaft 30 on the top that is positioned at framework 10 ' on.Driven roller 30 contacts with the intimate of describing subsequently that stacks with 40, and plays the effect of transferring power and be with 40 can rotate so that make to stack.Driven roller 30 provides power by the independent drive source (not shown) that is installed in framework 10 outsides, thereby and is driven.In this embodiment, only utilize a drive source to drive input roller 14 and driven roller 30.Obviously, can be respectively input roller 14 and drive source is provided separately with driven roller 30.
In the zone near driven roller 30, the part through curved frames 10 vertically forms fabricated section 32.In fabricated section 32, the first conduction band spare 34 be installed in rotation on first belt-guiding shaft 34 ' on.Stack and be with 40 to be wrapped on the first conduction band spare 34, and the first conduction band spare 34 first belt-guiding shaft 34 ' on be installed into free time (idle) state that is in, wherein only be with 40 driven rolls 30 to drive and when rotating, the first conduction band spare just rotates when stacking.
Stack and can twine (preferably, belt wheel) such as on it roller, axles with 40 and can be used as the second conduction band spare of describing subsequently 50 and distraction guide 52, and the first conduction band spare 34.
As Fig. 1 clearly shown in, driven roller 30 is installed into about the first conduction band spare 34 and is inclined upwardly.In addition, driven roller 30 to the first conduction band spares 34 are from medium
mInlet nearer relatively.Driven roller 30 arranges as described above, is with 40 so that more effectively the turning effort of driven roller 30 is passed to stack.In other words, rotate and downwards during sagging, stack band and can keep, thereby stack more effectively absorbing medium of band by the turning effort of driven roller 30 when stacking to the crooked circle in medium inlet with 40
mThe impact of transmitting.
Stack and be with 40 to be to work as medium
mBe introduced into when stacking in the space 12 and medium
mThe part of front end crash.When stacking band and medium
mFront end crash the time, stack and be with 40 to deform and absorb impact.A side that stacks with 40 is wrapped on the second conduction band spare 50 that is positioned at the first conduction band spare, 34 belows.Here, the second conduction band spare 50 is installed in than the inlet relatively farther position of the first conduction band spare 34 from medium.Therefore, also as shown in Figure 1, stack the band be wrapped under the state on the first conduction band spare 34 and the second conduction band spare 50, stack be with 40 by gravitys with circle to the medium inlet sagging.
Fig. 2 clearly show that the concrete shape that stacks with 40.With reference to accompanying drawing, a plurality of guide protrusions 42 form on stacking with 40 outside face to be protruded.A plurality of guide protrusions 42 are arranged at regular intervals and stack with on 40 the outside face.Work as medium
mBe with 40 whens collision, guide protrusions 42 boot media with stacking
mFront end, and at medium
mBe with after 40 collisions with stacking, guide protrusions 42 prevents that medium is along stacking with 40 outside face to lower slider and rotation.
Be used for working as medium
mWith stack be with 40 when collision boot media
mThe guide surface 44 of front end be formed obliquely in the both sides of guide protrusions 42.Guide surface 44 is formed obliquely and is boot media
mMake its front end and bottom surface 46 collisions.Guide protrusions forms the distance that makes between the guide protrusions 42 and is introducing medium
mThe relative broad in entrance.Be for boot media like this
mSo that collide fully itself and bottom surface 46.
In addition, because guide protrusions 42 is configured to have the interval of rule, although therefore at medium
mWith slip after the convexity collision, but medium
mGuide protrusions 42 by contiguous stumbles, thereby can prevent medium
mFront end exceedingly rotate.Area limiting between the convexity and medium
m The bottom surface 46 of front end crash.Can think that bottom surface 46 defines the outside face that stacks with 40 basically.
As stated, a part that stacks with 40 is wrapped on the second conduction band spare 50.The second conduction band spare 50 is installed in the below of the first conduction band spare 34.In addition, the second conduction band spare 50 is installed in than the inlet relatively farther position of the first conduction band spare 34 from medium.With the second conduction band spare 50 be installed in above-mentioned position so that stack be with 40 with circle to the medium inlet sagging.Stack and be with 40 can keep circle as stated, thus absorbing medium effectively
mImpact energy.
Above the second conduction band spare 50, distraction guide 52 be installed in rotation on separate belt-guiding shaft 52 ' on.Distraction guide 52 is installed at the gravity direction and the second conduction band spare 50 and vertically separates.The effect of distraction guide 52 is that the part interference that stacks with 40 that prevents to be wrapped on the first conduction band spare 34 is wrapped in the another part with 40 that stacks on the second conduction band spare 50.
Particularly, under distraction guide 52 not being set and stacking, because the distance that stacks between the relative part of band is narrow, therefore when stacking band and medium with 40 situation about only being wrapped on the first conduction band spare 34 and the second conduction band spare 50
mPossibly interfere stacking to be with in 40 during collision.Here; Because stacking between the first conduction band spare 34 and the distraction guide 52 do not have bending with 40 part but keeps tensioned state, so such problem possibly occur, promptly; If what stack band tightens part and the collision of its circular portion, stack then that be with 40 can't normal operation.In order to address this problem, distraction guide 52 to be set to stack with the distance between 40 the relative part with increase.In addition, owing to be provided with distraction guide 52, thus increased the tensioning degree that stacks with 40, stack like this and be with 40 can keep circle well.
Being similar to the first conduction band spare, 34, the second conduction band spares 50 is installed into and can under idle condition, rotates with distraction guide 52.
In this embodiment, simultaneously, thin plate roller 16 preferably is controlled so as to driven roller 30 velocity of rotation of the two is differed from one another.Particularly, driven roller 30 should doubly be controlled to and make its velocity of rotation relatively less than the velocity of rotation of thin plate roller 16.Be the medium that is overlayed on the stay bearing plate 22 in order to improve like this
mThe degree that stacks (stacking degree).
More specifically, be introduced into the medium that stacks in the space 20
mFront end with stack be with 40 the collision, medium falls then.At this moment, in order to stack medium equably
m, the power that is produced in the time of need knocking medium through the blade 18 at thin plate roller 16 is with medium
mOverlay on the stay bearing plate 22, simultaneously medium
mFront end do not rotate.
If the velocity of rotation that stacks with 40 is controlled so as to the velocity of rotation that is higher than thin plate roller 16, medium so
mFront end can be directed to protruding 42 to pressing down, thereby medium m can rotate on the clockwise direction in the drawings.If medium
mWhen rotating, overlayed stay bearing plate 22, then possibly stacked failure.Therefore, in this embodiment, the velocity of rotation Be Controlled of thin plate roller 16 gets higher, thereby medium is overlayed on the stay bearing plate 22, and the rear end of medium is by blade 18 alignment of thin plate roller 16.
Form the outlet (not shown) in the bottom of framework 10.Overlayed the medium on the stay bearing plate 22
mBe released through outlet.Logical medium
mThe unit of crossing pick-up roller (not shown) for example etc. is outwards discharged one by one.
Hereinafter, detailed description had above-mentioned structure, the medium shock absorber of automatic media dispenser of the present invention and the operation with media stacking apparatus of this device.
Fig. 3 a to 3c illustrates the view that medium is stacked by preferred implementation of the present invention.
With reference to accompanying drawing, will pass through the medium of medium delivery unit
mIntroduce and overlay and stack in unit or the medium memory cell temporarily.At medium
mA surperficial closed contact input roller 14 (introduce down medium referring to Fig. 3 state a)
mIn other words, through rotating medium on input roller 14 anticlockwise direction in the drawings
mIntroduced one by one and stacked in the space 12.
Be introduced into the medium that stacks space 12
mBe positioned at stacking of its place ahead be with 40 the collision.In case medium
mBe with 40 collisions with stacking, then shown in Fig. 3 B, stack with a part of 40 at medium
mIntroducing power (introduction force) effect down and crooked.As a reference, introduce medium
mSignal be issued, driven roller 30 is provided on power and in the drawings the clockwise direction by drive source and rotates, thereby makes stacking of contact with the intimate of driven roller 30 be with 40 rotations in the counterclockwise direction.At this moment, the velocity of rotation of driven roller 30 is controlled so as to the velocity of rotation less than thin plate roller 16.
In Fig. 2 shown in detail in figs and medium
mCollision stack a part with 40.Because the guide surface 44 of guide protrusions 42 is formed obliquely, therefore work as medium
mBe with 40 whens collision, medium with stacking
mFront end can be by guide surface 44 guiding and then and bottom surface 46 collisions.Then, although the front end of medium slides medium after colliding with bottom surface 46
mFront end stumble by the guide protrusions 42 that is formed at bottom surface below.Therefore, medium
mFront end can not rotate on the clockwise direction in the drawings, and can stably be stacked.
Once more with reference to Fig. 3 B, at medium
mUnder the state that stacks with 40 collisions, medium
mThe rear end promote medium then downwards by the blade 18 of thin plate roller 16
mOverlayed on the stay bearing plate 22.Fig. 3 c clearly show that medium
mBlade 18 by thin plate roller 16 promotes downwards.
In addition, because medium
mFront end be with 40 collisions, and medium with stacking
mThe rear end promote thereby medium downwards by the blade 18 of thin plate roller 16
mAlignment, thereby the inwall closed contact of rear end and framework 10.In other words, medium
mThe rear end about stacking left wall (in the drawings) alignment in space 12.Therefore, the no matter kind and the size of medium, medium
mCan be about one of which end alignment, thus the degree that stacks of medium m can be improved.
Overlay the medium on the stay bearing plate 22
mMove down, and borrowing the outlet of the bottom through being formed at framework 10 to be discharged into the framework outside one by one.
In the present invention, be introduced into the medium that stacks the space and collide, overlayed on the stay bearing plate then with stacking band.Because medium has obtained alleviating with stacking the impact that produces when plate collides, thereby the front end that has prevented medium is damaged.
In addition, in the present invention, form a plurality of guide protrusions stacking to be with at regular intervals, thus the front end that has prevented medium with stack after the band collision medium and slide and rotate.Therefore, because medium can be stacked equably, thereby has the advantage of the degree that stacks that improves medium.
Further, in the present invention, the front end of medium with stack the band collision after, medium is promoted downwards to be overlayed on the stay bearing plate then by the blade of thin plate roller.Therefore, because medium aligns about its rear end and quilt is stacked, thereby improved the degree of stacking.
If the degree that stacks of medium is improved as described above, so medium can normally be discharged into the outside and can not occur any mixed and disorderly, thereby improved the reliability of medium.
Scope of the present invention is not limited to above-mentioned embodiment, and is limited appended claim.Obviously, those skilled in the art can carry out various modifications and change to the present invention in the scope of the present invention that is defined by the claims.
