Fig. 2 is the birds-eye view of paper pickup disengagement gear, the amplification stereogram of Tu3Shi supply department and periphery thereof, and Fig. 4 is the block diagram of the state illustrated at supply department's configuration paper.
As shown in Figures 2 to 4, the supply department 2 of paper pickup disengagement gear 10 has smooth diapire 21a and the guiding wall 21b from substantially vertical thirty years of age of diapire 21a.Supply department 2 is keeping being positioned in multiple papers stacked on diapire 21a with upright state towards the supplier of pickup separation unit 3 on A.Guiding wall 21b by contacting to each end of multiple papers of movement on A with supplier, thus guides the movement of multiple paper.
Supply department 2 there is the master tape 22a be arranged on diapire 21a, subband 22b further and on diapire 21a to supplier to the stay bearing plate 23 of A movement.Master tape 22a and subband 22b contacts with by each end of multiple papers be positioned on diapire 21a, and drives to supplier to A independently of each other.Thus, master tape 22a makes the multiple papers be positioned on diapire 21a move to supplier to A, and subband 22b adjusts multiple paper posture separately.
Stay bearing plate 23 contacts to the paper of the rearmost end on A with the supplier that is positioned in the multiple papers be configured on diapire 21a, and pushes multiple paper to supplier to A, with the driving synchronizing moving of master tape 22a.Thus, stay bearing plate 23 makes the multiple papers be positioned on diapire 21a move to supplier to A.
As shown in Figure 4, in paper pickup disengagement gear 10, the diapire 21a of supply department 2 forms horizontal surface, and guiding wall 21b forms the vertical surface orthogonal with horizontal surface.Have in each paper on the surface of rectangular shape, the limit of Width is roughly parallel to the vertical direction.In the both ends on the limit of the Width of each paper, the end of vertical direction lower side is formed the surface maintenance of the diapire 21a of horizontal surface.
The limit of the length direction of each paper and horizontal direction parallel, in the both ends on the limit of its length direction, guiding wall 21b is pushed up in the end of the transport direction B side of pickup separation unit 3 described later.Thus, multiple paper configures as follows in supply department 2, being alignd by diapire 21a in the end on the limit of the Width of its vertical direction lower side, is alignd by guiding wall 21b in the end (that is, the leading section of transport direction B) on the limit of the length direction of its transport direction B side.
Pickup separation unit 3 has secondary pickup section 31, main pickup section 32, separation unit 33.
Secondary pickup section 31 is configured in the upstream side of main pickup section 32 on the transport direction B being parallel to horizontal direction.Secondary pickup section 31 has, and accessory air-space 31a, is connected to negative pressure generator (not shown, the suction side etc. of such as blowing engine); Absorption band 31b, such as, is driven by drive motor (not shown, stepping motor etc.).
Accessory air-space 31a has secondary directing plate 31d, this secondary guide plate 31d is formed with the multiple peristome 31c to supply department 2 opening.Secondary directing plate 31d is rectangular plate-like, and multiple peristome 31c is communicated with the inside of accessory air-space 31a.Thus, the peristome 31c of secondary directing plate 31d is applied in negative pressure (subatmospheric pressure).Secondary directing plate 31d guides absorption band 31b to the movement of transport direction B.
Absorption band 31b is the endless belt forming multiple adsorption hole 31e, and region is overlapping with a part of secondary directing plate 31d at least partially for it.In the region that absorption band 31b is overlapping with secondary directing plate 31d, absorption band multiple adsorption hole 31e of 31b is communicated with at least partially with multiple peristome 31c's of secondary directing plate 31d.Thus, multiple adsorption hole 31e of absorption band 31b apply negative pressure by multiple peristome 31c by accessory air-space 31a.
In the region of the absorption band 31b overlapping with secondary directing plate 31d, 31b is opposite on A supplier with the multiple papers remaining on supply department 2 for absorption band, and at absorption band 31b with under the state being parallel to transport direction B extension configuration, absorption band 31b moves to transport direction B.Thus, when multiple adsorption hole 31e is applied in negative pressure, absorption band 31b passes through absorption to pick up supplier to the paper foremost A from the multiple papers supplied by supply department 2.Then, the paper by absorption pickup is sent to transport direction B with specified speed by absorption band 31b.
The specified speed of absorption band 31b is set to be less than the speed of pick-up tape 43 described later.Thus, first paper by absorption pickup first paper, and is sent to while main pickup section 32 from supply department 2 by secondary pickup section 31, the rear end of first paper by after accessory air-space 31a, by absorption pickup second paper.
Then, second paper, to send the speed of the speed of first paper to transport direction B lower than main pickup section 32, is sent to main pickup section 32 by absorption band 31b.Thus, on transport direction B, between first paper and second paper, set the interval being more than or equal to predetermined distance value, to eliminate the overlapped of first paper and second paper.
Main pickup section 32 is configured in the downstream of secondary pickup section 31 on transport direction B.The pick-up tape 43 that main pickup section 32 is had valve gear 42, such as, driven by drive motor (not shown, stepping motor etc.).
Valve gear 42 has the body part 51 one side being arranged main boot plate 61.Main boot plate 61 is opposite on A supplier with the multiple papers remaining on supply department 2.Main boot plate 61 moves to transport direction B for guiding pick-up tape 43.
Body part 51 and main boot plate 61 are formed by the multiple through holes (not shown) be interconnected.These through holes are connected with the vacuum pump (not shown) being arranged on valve gear 42.Thus, the through hole of body part 51 and main boot plate 61 is applied in negative pressure.
Pick-up tape 43 is the endless belt being evenly formed with multiple adsorption hole 43a in whole region.Pick-up tape 43 is erected on multiple pulley (not shown), and this pulley is included in two pulleys 64a, 64b transport direction B being configured in valve gear 42 both sides.Pick-up tape 43 is configured to, and the region at least partially in pick-up tape 43 is overlapping with main boot plate 61.In the region of the pick-up tape 43 overlapping with main boot plate 61, the multiple adsorption hole 43a in pick-up tape 43 is communicated with the through hole be formed on main boot plate 61 (not shown).Thus, multiple adsorption hole 43a of pick-up tape 43 are applied in negative pressure.
In addition, overlap the region of the pick-up tape 43 on main boot plate 61 with under the state being parallel to transport direction B extension configuration, pick-up tape 43 moves to transport direction B.Thus, when multiple adsorption hole 43a is applied in negative pressure, pick-up tape is passed through to send the paper to transport direction B by secondary pickup section 31 while absorption pickup is supplied to supplier to A by supply department 2.Then, pick-up tape 43, with the speed faster than secondary pickup section 31 rate of delivery, sends the paper by absorption pickup to transport direction B.Now, the guiding wall 21b of supply department 2 sends paper by pick-up tape 43 to transport direction B for guiding.
As shown in Figure 2 and Figure 3, separation unit 33 is positioned at the downstream of the guiding wall 21b of supply department 2 on transport direction B, relative to the paper sent by main pickup section 32 to transport direction B, is configured in the opposition side of main pickup section 32.Separation unit 33 has two pickup peventing members 71.Two pickup peventing members 71 in the downstream of the transport direction B of pick-up tape 43, two pickups peventing member 71 and pick-up tape 43 across gap S-phase opposed configure.Gap S is set as such as approximately about 0.5mm.
Fig. 5 is the block diagram of two pickup peventing members, and Fig. 6 is the lateral plan of two pickup peventing members.
As shown in Figure 6, when picking up multiple papers by pick-up tape 43 simultaneously, two pickup peventing members 71, by the paper of absorption two pickup peventing member 71 side, make this paper stop, thus are admitted to space correction portion 7 when preventing multiple paper roughly the same.
Two pickup peventing members 71 have the body 72 formed by such as poly-urethane rubber (elastomeric material) elastomeric material.Because body 72 is formed by elastomeric material, the lightweight of body 72 can be made, and shortening causes because paper enters body 72 to be out of shape afterwards until body 72 returns to the time of original form.
In pick-up tape 43 side (front) of body 72 and the approaching side of paper (upstream side of transport direction B) is formed with arc surface 72a.
In arc surface 72a, in the position closest to pick-up tape 43, that is, be formed with multiple (such as, six) adsorption hole 73 in the front end of arc surface 72a.These adsorption holes 73 are along being orthogonal to the direction of transport direction B to configure at equal intervals.Each adsorption hole 73 such as, connects with the depression generator (not shown, vacuum pump etc.) being arranged on separation unit 33.Thus, each adsorption hole 73 is applied in negative pressure.
The base end side (opposition side of arc surface 72a) of body 72 is provided with base plate 74, and this base plate 74 is for being fixed on paper pickup disengagement gear 10 by body 72.In addition, body 72 arc surface 72a and be formed in this arc surface 72a side 72b on be provided with the back plate 75 covering these arc surfaces 72a, side 72b.
Base plate 74 and back plate 75 use various adhesivess etc. to be fixed on body 72.In addition, the base end side of back plate 75 is fixed on base plate 74 by adapter plate 76 and bolt 77.
Back plate 75 has following effect, prevents body 72 from causing being stripped from base plate 74 because of shock when paper enters, and for guiding body 72 to return to original shape after body 72 distortion.Further, be preferably corrosion-resistant steel as the material of back plate 75.Owing to using corrosion-resistant steel, the elasticity of back plate 75 and antirust can be guaranteed.In addition, the wall thickness of back plate 75 is such as set as about 0.1mm, makes back plate 75 not affect the distortion of body 72 as far as possible.
Further, in the surface of back plate 75, the position of the arc surface 72a corresponding to body 72 is provided with protective case 78.Protective case 78 is for preventing deterioration, the wearing and tearing because clashing into the body 72 that causes and back plate 75 when paper enters.
Protective case 78 is such as formed by metal sheets such as stainless steel sheets.The wall thickness of protective case 78 is set as such as approximately about 1mm.By such formation, protective case 78 can be out of shape along with the distortion of body 72.In addition, in back plate 75 and protective case 78, part corresponding with the adsorption hole 73 of body 72 is respectively formed with adsorption hole 79.Thus, negative pressure is applied by the adsorption hole 73 of body 72 to the adsorption hole 79 of protective case 78.
Here, in protective case 78, around adsorption hole 79, implement the rough surface process M for improving protective case 78 surface friction coefficient.As rough surface process M, can illustrate diamond coatings, sandblasting, thermal spraying etc.Such as, the coefficientoffrictionμ of the part of rough surface process M will not be carried out 'when being 0.1, implement rough surface process M, the coefficientoffrictionμ making the part implementing rough surface process M is about 0.3-0.5.
Here, refer to surrounding's enforcement rough surface process of adsorption hole 79, such as, as shown in Figure 7, when being d by the diameter of adsorption hole 79, at the periphery from adsorption hole 79 along in the scope of transport direction B distance d/2, effects on surface implements rough surface process M.Such as, in addition, as shown in Figure 8, relative to the diameter d of adsorption hole 79, also can coaxial with adsorption hole 79 on, implement the rough surface process M in the scope of diameter about 2d.
Get back to Fig. 2, Fig. 3, space correction portion 7 is together configured for a part for the transport mechanism 80 transporting paper with multiple various conveyor belt and roller bearing (not shown).Space correction portion 7 is configured in the downstream of separation unit 33 on transport direction B.Space correction portion 7 has sponge roller 81 and the driven roller 82 of the mutually opposing configuration of mode clamping main transport path 4.Sponge roller 81 for having elastomeric flexible roller, according in main transport path 4 conveyance paper thickness change and be out of shape.
Driven roller 82 such as, by drive motor (not shown, AC servomotor) rotary actuation, changes the conveyance speed of paper by the acceleration and deceleration rotated.Thus, when the interval (gap) of the paper clamped by sponge roller 81 and driven roller 82 and paper leading in conveyance direction is less than specified value, space correction portion 7 makes the conveyance speed reduction of paper, thus expands interval.On the other hand, when the interval of the paper clamped by sponge roller 81 and driven roller 82 and paper leading in conveyance direction is greater than specified value, space correction portion 7 makes the conveyance speed of paper accelerate, thus reduces interval.
Next, based on Fig. 2, Fig. 6, Fig. 9, Figure 10, the effect of separation unit 33 is described.
Fig. 9 illustrates the instruction diagram of paper by the movement of two pickup peventing members during separation unit.

Radius of curvature R is set as meeting following formula:
R≧(Hmax-S)×2-t···(1)
By meeting mathematical expression (1); the position of the contact point P that protective case 78 can be contacted with paper (with reference to Fig. 9) is set as, the line connecting contact point P and arc surface 72a center and the angle θ that is connected the adsorption hole 79 of protective case 78 and the line at arc surface 72a center and formed are for being less than or equal to 60 degree.In other words, can set in the front end of pick-up tape 43 side from body 72 the contact point P contacted with paper to R/2.Therefore, when body 72 is pushed by paper, can by this thrust pressure effect to the direction of the power of body 72, as the direction of reliably distilled edition body 72.
Further, preferably, the size of the length direction (above-below direction in Fig. 6) of body 72 is set as about more than 5 times of the maximum deformation quantity (Hmax-S) of this body 72.By such setting, the compressive deformation that as far as possible can reduce body 72 is crooked, can improve the durability of endurance failure when body 72 is out of shape repeatedly.
In addition; the rough surface process M implemented protective case 78 only around adsorption hole 79 (with reference to Fig. 5); if two pickup peventing member 71 compressive deformations and towards transport direction B downstream slightly to layback time, be implemented the downstream of part towards transport direction B of rough surface process M.Therefore, when the paper with thickness is contacted with protective case 78, paper contacts with the part not implementing rough surface process M in protective case 78, thus the friction force between protective case 78 and paper can not increase.Thus, paper can smoothly by between two pickup peventing members 71 and pick-up tape 43.
Next, the situation sending two overlapping papers from main pickup section 32 is described.
As shown in Figure 10 A, when the paper transported by main pickup section 32 picks up the gap S between peventing members 71 and pick-up tape 43 with two overlap conditions by two, as shown in Figure 10 B, in the paper of overlap condition, the paper of two pickup peventing member 71 sides is adsorbed by the adsorption hole 79 of two pickup peventing members 71 and stops then and there.Paper can not act on large friction force between the paper of overlap condition, and therefore, the paper of pick-up tape 43 side is directly sent to space correction portion 7.
Here, in the protective case 78 of two pickup peventing members 71, around adsorption hole 79, be implemented rough surface process M.(with reference to Fig. 5).Therefore, the friction force between the surrounding of adsorption hole 79 and the paper adsorbed by this adsorption hole 79 improves.Thus, while weakening the adsorption affinity (negative pressure) of two pickup peventing members 71, reliably can be stopped in overlap condition paper by these two pickup peventing members 71.
In addition, be formed in the multiple adsorption holes 79 on protective case 78, along being orthogonal to the direction of transport direction B to configure at equal intervals (with reference to Fig. 5).Therefore, it is possible to prevent the paper by two pickup peventing members 71 are adsorbed from rotating (crooked) centered by a point.
Next, as shown in figure l oc, if the paper of pick-up tape 43 side is completely by two pickup peventing members 71, then pick-up tape 43 side is adsorbed to by the paper that two pickup peventing members 71 stop.Then, this paper is directly sent to space correction portion 7.
Here, the adsorption affinity of valve gear 42 pairs of papers of main pickup section 32 is set as the adsorption affinity being sufficiently more than separation unit 33 pairs of papers.Therefore, when the paper of pick-up tape 43 side is completely by two pickup peventing members 71, pick-up tape 43 side is reliably adsorbed to by the paper that two pickup peventing members 71 stop.
Further, open in class at the two pieces of paper of overlap, when the thickness of at least one paper is enough thick, the paper of two pickup peventing member 71 sides can not arrive the adsorption hole 79 of protective case 78 and stop in its front.That is, the paper of two pickup peventing member 71 sides pushes two power of picking up peventing members 71 open becomes resistance, and paper is stopped, and during this, the paper of pick-up tape 43 side is sent to space correction portion 7.Therefore, with the thickness of paper independently, overlapping paper is reliably separated by separation unit 33.
In addition, as previously described, the specified speed of the absorption band 31b in secondary pickup section 31 is set smaller than the speed of the pick-up tape 43 in main pickup section 32.Therefore, be provided with the interval of more than predetermined distance between the paper (first paper) sent at first from supply department 2 and the next paper (second paper) sent, thus first paper and second paper overlap can be eliminated.Therefore, it is possible to prevent by two papers of stopping of pickup peventing members 71 be positioned on transport direction B again more overlapping than the paper of this paper upstream side.
So, in two pickup peventing members 71 of present embodiment, the protective case 78 be arranged on body 72 has been implemented rough surface process M.Therefore, when transporting paper by pick-up tape 43 with overlap condition, the friction force of the part being implemented rough surface process M can be utilized, reliably stop the paper of two pickup peventing member 71 sides.Thereby, it is possible to prevent multiple overlaps of paper from sending, thus prevent to transport obstacle.In addition, without the need to strengthening the adsorption affinity of separation unit 33, also can strengthen the stop force of paper, can prevent multiple overlaps of paper from sending, thus can miniaturization paper pickup disengagement gear 10 (being arranged on the depression generator etc. of separation unit 33).
In addition, body 72 can the elastomeric material of elastic deformation be formed by according to the thickness of paper, and, around the adsorption hole 79 of protective case 78, be implemented rough surface process M.Therefore, while effectively can stopping overlapping paper by adsorption hole 79, the paper with thickness is prevented to be implemented being partially damaged of rough surface process M.
Further, the protective case 78 of two pickup peventing members 71 is metal sheet (such as stainless steel sheets).Therefore, it is possible to while guaranteeing the rigidity of protective case 78 self, the friction coefficient not implementing the part of rough surface process M is set as lower.Thus, paper is underlapped and paper is transported one by one time, paper can be smoothly through two pickup peventing members 71 upper surface.
In addition, the adsorption hole 79 of protective case 78 is multiple to be formed at equal intervals along the direction being orthogonal to transport direction B.Therefore, adsorption hole 79 can prevent the paper by two pickup peventing members 71 are adsorbed from centered by a point, rotating (crooked).That is, when making paper stop on a point, likely crooked centered by this point.But, by making paper stop at least two points, paper can be prevented crooked.
Further, two pickup peventing members 71 are in the downstream of the transport direction B of pick-up tape 43, arranged opposite across gap S relative to pick-up tape 43.Therefore, when transporting paper by pick-up tape 43 with overlap condition, a stopping in these papers can be made by two pickup peventing members 71, and another is reliably sent to space correction portion 7 by pick-up tape 43.
Further, in the body 72 of two pickup peventing members 71, in pick-up tape 43 side (front) and the approaching side of paper (upstream side of transport direction B) is formed with arc surface 72a.Therefore, two pickup peventing members 71 successfully can receive paper.
Further, the radius of curvature R of arc surface 72a is set as meeting mathematical expression (1).Therefore, when body 72 is pushed by paper, can using the direction as reliably distilled edition body 72, the direction that is applied to the power of body 72 by this thrust pressure.
Further, in the above-described embodiment, the situation implementing rough surface process M around the adsorption hole 79 only in the protective case 78 of two pickup peventing members 71 is illustrated.But, be not limited to this, also can implement rough surface process M on the whole surface of protective case 78.In addition, in the whole surface of protective case 78, also can only to implementing rough surface process M about the half comprised around adsorption hole 79.Now, the friction coefficient caused by rough surface process M must be set as that rough surface process M does not damage paper.
In addition, in the above-described embodiment, the situation of embodiment on protective case 78 as the rough surface process M by diamond coatings, sandblasting, thermal spraying is illustrated.But rough surface process M is not limited to this, also can at the adhesive tape of the surface mount raising friction drag of protective case 78 or rubber sheet etc.Now, preferably, according to the frequency of utilization of bill handling device 1, operation is changed in the stickup carrying out adhesive tape or rubber sheet.
Further, in the above-described embodiment, the situation that protective case 78 is formed by such as stainless steel sheet is illustrated.But protective case 78 is not limited to this, as long as the material that the material surface friction coefficient of protective case 78 is lower.Such as, also can be the engineering plastics etc. considering rub resistance.
According to paper pickup disengagement gear and the bill handling device of embodiment described above; protective case 78 due to two pickup peventing members 71 implements rough surface process; therefore, it is possible to reliably prevent the phenomenon that multiple overlaps of paper are sent, thus can prevent to transport obstacle.In addition, weaken the adsorption affinity of separation unit 33 as far as possible, thus multiple overlaps of paper can be prevented and the phenomenon sent, therefore, it is possible to miniaturization paper pickup disengagement gear 10 (being arranged on the depression generator etc. of separation unit 33).
Describe several embodiment of the present invention, but these embodiments exemplarily propose, and be not intended to limit protection scope of the present invention.These embodiments can be implemented with other various ways, in the scope not departing from invention aim, can carry out various omission, replacement, change.These embodiments or its be out of shape be included in invention protection domain or aim in, be also contained in the invention recorded in claims and its equivalent protection domain.
