Apparatus for dispensing notes

Abstract: Problem: A lot of circulating notes have the problem that the contact friction is insufficient when the sending-out means is a small tire, since the notes were bent at the center thereof. That is, there is the problem that the tire of sending-out means runs idly in case of the note bent at the center. Therefore, the note is not sent out surely. Solution : An apparatus for dispensing notes comprising at least suction means having an opening (M) to absorb the notes (B), exhaust means (23, 24) which is provided with this suction means, and sending-out means provided extending over the opening of the suction means, for sending out the absorbed notes against the absorption thereof.

Description: The invention relates to an apparatus for dispensing notes according to the preamble of claim 1. Especially, this invention relates to an apparatus for dispensing or paying out notes which are pieces of a paper currency. Additionally, this invention relates to an apparatus for counting and dispensing or paying out notes. This invention concretely concerns such apparatuses suitable for machines in which the notes are used, such as vending machines, for instance a ticket vending machine, exchange machines and so on. The concept of "note" in this invention contains, of course, currency notes and bodies made of bendable paper or plastics. Further, the concept of "note" in this invention contains, of course, small card bodies such as flexible telephone cards, commutation ticket cards and so on. As a conventional note pay-out device, there is, for instance, this applicant's Japanese Patent Application 8-188006. This note pay-out device has, as shown in Figure 6, a suck means 21 with a rectangular pipe shape which has an open mouth 22 for adsorption of the note at the lower portion thereof. An exhaust means 26 is provided on the suck means and sending-off means 27 to send off the note which is adsorbed is provided within the suck means However, there was a problem that the pay-out device mentioned above lacks certainty, especially, when the note is sent off. A lot of circulating notes have the characteristic that the notes were bent at their centers causing the problem that the contact friction becomes insufficient when the sending off means is a small tire. That is, there is the problem that the tire of the sending off means runs idly in case of the note bent at the center. Therefore, the note is not sent off surely. Furthermore, from the documents DE 1267005 B, US-A-5 074 539 and FR-A-2 395 213, apparatuses for dispensing subject-matters made of bendable paper are known comprising suction means, an opening to adsorb the bendable paper and exhaust means which are provided with the suction means, and sending means for sending the bendable paper, wherein the sending means are provided extending over the opening of the suction means. This invention is developed for the purpose of providing a device capable to send out or dispense the notes one by one surely and speedy. This invention is developed for the purpose of providing the device capable to count the notes one by one surely and speedy and dispense them. This invention is developed for the purpose of providing the device capable to send out the notes surely, while miniaturizing the device and simplifying its structure. This object is achieved by the apparatus for dispensing bills according to claim 1. Further developments of the invention are given in the dependent claims. Further advantages, objects, features and developments of the invention are apparent to the skilled person from the following description of an embodiment referring to the drawings, of which: Fig. 1 is a perspective view of an outline of an apparatus according to a first embodiment of the invention showing its essential parts; Fig. 2 is a perspective view of a major part of the apparatus of Fig. 1; Fig. 3 is an elevation view of the apparatus of Fig. 1 from the front; Fig. 4 is a side view of the apparatus of Fig. 1; Fig. 5 is a top view of the apparatus of Fig. 1; Fig. 6 is a front view of a prior art device; Fig. 7A is a sectional view from one side of an outline of an apparatus according to a second embodiment of this invention; Fig. 7B is sectional view of the apparatus of Fig. 7A, in which the upper part of Fig. 7A is removed; Fig. 8 is asectional view corresponding to Fig. 7A seen from the other side; Fig. 9 is a sectional view showing a part C of the second embodiment; Fig. 10 is an outline view for explaining the operation of the apparatus of Fig. 7A; and Fig. 11 is an outline view showing the apparatus of Fig. 7 seen from the upper side. Fig. 1 shows an apparatus according to a first embodiment of this invention in a use condition posture. A slightly big T-shaped side board which is shown in the upper center of Figure 1 is a base board 11. At the central end part 12 of base board 11, a cover board 13 which is curved with a half pipe form is fixed in a hang-down state. Inside the bottom end of cover board 13, a slightly small trapezoid bottom board 14 is fixed. Near the center underside of base board 11, a rectangular installation part 15 is is fixed in a hang-down state. Also, at both sides of central end part 12, rectangular side parts 16 and 17 are fixed in a hang-down state, respectively. As a result, a big opening M is formed by the central end part 12, the pair of side parts 16 and 17, and the bottom board 14. In the upper and lower portions of installation part 15 with respect to its vertical length, two slightly big piercing holes 21 and 22 are formed. Outside these piercing holes 21 and 22, small fan apparatuses 23 and 24 are fixed at the installation part 15, respectively. A slightly big reverse L-shaped body shown in Fig. 1 is a frame body 31. In Fig. 2, the concerned frame body 31 is removed from base board 11. At the upper end part of frame body 31, a slightly big board part is formed of right-angled bent board parts 32, 33. Using a rectangle installation part 32 which is one of these bent board parts, the frame body 31 is fixed on the base board 11. On the other rectangle installation part 33, a small electric motor 25 is fixed. A pulley 26 for driving a belt 38 having a big ring form is put on the turn axis of electric motor 25. The pulley 26 is a pulley with teeth and meshes with a teeth part on the back side of belt 38. In addition, the electric motor 25 is a step motor which can rotate in both positive and reverse turns. The lower end part of frame body 31 is formed slender and is a guide part 34 of the endless belt 38. Small spacers 35 for fixation are installed on each end and center parts of this spindly guide part 34, respectively. Through these three spacers 35, a slender guide fragment 36 formed like the guide part 31 is installed to the guide part 31. Between the pair of the guide part 34 and the guide fragment 36, four small rollers 37 are provided, being free to rotate. These rollers 37 are means to guide the endless belt 38 and are preferably provided near each of the spacers 35. In addition, the guide part 34 and guide fragment 36 are formed such that they are free to be inserted into slit holes which are formed at the center of each outside edge of central end part 12 and bottom board 14, respectively. Therefore, the frame body 31 can be fixed on the base board 11 through the installation part 32 such that the belt 38 spans or crosses the opening M, and it is possible to remove the frame body 31 from the base board 11. In other words, belt 38 extends over the opening M. Next, the operation of the first embodiment which has the above-mentioned composition is described. A control device (not shown) is connected to and controls the operation of the means and devices of the apparatus. A lot of notes B, for instance 1000 yen bills, are arranged to a bunch or stack standing upright in front of the open mouth M (see Fig. 4 and 5). The bunch of notes B is slightly pressed toward the open mouth M, for instance by an appropriate pressing means (not shown) like a biased plate or the like, or is kept essentially pressure-free in front of the open mouth M. Thus, when the fan devices 23 and 24 are driven, air is sucked through the open mouth M and exhausted at the backside of fan devices 23, 24 (the right side in Fig. 4). As a result, a negative pressure is caused at the open mouth M and the first note B of the bunch in front of mouth M is adsorbed at this open mouth M. At the same time, the electric motor 25 is controlled to rotate positively, i.e. the turn axis and pulley 26 rotate in the clockwise direction in Fig. 4. The thin belt 38 made of rubber will run in the direction shown by the solid arrow in the drawings. That is, by the face friction of belt 38 made of rubber, the first note B of the bunch adsorbed at the open mouth M is drawn from the bunch in the moving direction of the portion of belt 38 contacting the note, i.e.in the direction of the solid arrow in Fig. 4. Thus, the top part of first note B is sent in the direction toward above (shown by the chain-line arrow in Fig. 4) and placed between rollers (not shown). As a result, the first note B is compulsorily drawn up in the direction toward above by the not shown rollers (the chain-line arrow in Fig. 4). At this time, the passage of the note between the rollers is detected by sensors (not shown), and the electric motor 25 is controlled to rotate reversly. As a result, the first note B moved as described above is surely sent out in the direction of the chain-line arrow. Thus, by the reverse-run of belt 38, the second note B of the bunch is prevented from being missent or moved together with the first note to the upper side. The endless belt 38 is made of natural rubber or synthetic rubber. Although, in this embodiment, the single belt 38 is provided, it is of course possible that two or more belts 38 are arranged near each other. Although, in this embodiment, the belt 38 is of a slender-shape, it is of course possible that a belt which is wide and has a lot of vents is used. Also, it is of course possible that a caterpillar type belt such as a rubber chain is used, replacing the belt 38. Although a plurality of spacers 35 are installed on the guide part 34, it is of course possible that only a pair of rollers 37 is installed. In this case the rollers 37 could, for instance, be mounted secured and rotatable on minute axes fixed on the guide part 34, respectively. As a result, the guide fragment 36 will become unnecessary and omitting the guide fragment 36 makes the installation of belt 38 extremely easy. In this embodiment, two fan devices 23 and 24 are used. However, it is of course possible that only one fan device is used. Also, since the frame body 31 can be easily detached from the base board 11, it is clear that the exchange of belt 38 and so on may become extremely easy. In addition, since all necessary parts are fixed on the base board 11, it is clear that this device can be used, whether the base board 11 is mounted inclined or upright. In other words, of course the device can be used in spite of positioning the mouth M of this device vertically or horizontally up or below the fans or slanted. According to this embodiment, a note sending or dispensing device with a small and simple structure can be offered, by the combination of a small fan, a belt made of rubber, and an electric motor. Moreover, according to this embodiment, the big advantage is obtained that notes can be surely and speedily sent out one by one by means of a device having a simple constitution. An apparatus for counting and dispensing (paying out) notes according to a second embodiment of this invention is explained in the following referring to Fig. 7A, 7B and 8 to 11. This apparatus has a shape similar to a hand hanging suitcase, i.e the whole apparatus has a box form. In the posture of Fig. 7A, the left side is the front side, the right side is the back side, the lower side is the bottom side and the upper side is the top side of the apparatus such that the side from which the sectional view is seen is the right side of the apparatus. A prominence or protruding part of the apparatus shown at the left side of the upper part of Fig. 7A is a discharge (ventage) room E in which a desired number of counted bills (as calculated before, for instance in order to pay out a specific amount of money) are prepared to be paid out. The bills to be prepared to be paid out are stored in a case C of box form which occupies almost half of the inside of this apparatus (see Fig. 7A and 9). The case C is open at the upper part thereof and the case C is adapted to be put into and taken out of this apparatus from one side thereof. Inside the case C, a lot of bills are arranged in an upright condition with respect to their larger length (see for example Fig. 1 and 9). A device D for sending the bills in the case C one by one toward above is installed at the back side of the apparatus (right side in Fig. 7A). The device D for sending the bills, i.e. for dispensing the bills stored in case C one by one toward above, is formed like the first embodiment shown in Fig. 1 to 5. On both sides of the apparatus, i.e. on the right and on the left side, a device F for bringing a part of a bill bundle in the case C in a pressure-less free condition is formed, respectively (see Fig 7B). In other words, one pair of the freeing devices F brings a plurality of bills which approach the sending device D in the free condition as described afterwards. In the upper part of the apparatus (right upper part of Fig. 7A), a device T (which includes the not shown rollers of the first embodiment drawing up the note) for taking in and forwarding farther above the note which is sent above from the sending device D is provided. At the center of the top of the apparatus (center top of Fig. 7A), a room R for temporarily storing the bill from the taking-in device T is formed. Further, when notes in the desired number (calculated before to pay out a specific amount of money) are stored in the collection room R, all these notes are sent to the ventage room E. The ventage room is formed such that the notes send to the ventage room E can be pulled out with the fingers of a hand. The box-shaped case C pulled out from the apparatus is shown in Fig. 9. A rectangular board 51 is provided upright in the case C, and the board 51 is movable horizontally. A pair of rails 52 is formed in the bottom of case C. Moreover, in each bottom corner part of upright board 51, a couple of small rollers 53 which sandwich the rails 52 are formed, respectively. In addition, a small collection room 54 is formed on the front side (the left side in Fig. 9) of case C. When a note from storage room R is collected, this collection room 54 is used (see Fig. 7A). A plate spring 59 is set in the collection room 54, and the collected notes are held. A window frame 55 is formed on the back side (the right side in Fig. 9) of case C. A belt spring device 56 of a whirl type is set at the center of the bottom part of window frame 55. The point part of belt spring 57 of belt spring device 56 is fixed to the center of the bottom part of upright board 51. Therefore, the upright board 51 will always be pulled in the direction toward window frame 55 by the belt spring 57. A lot of notes B can be stored between the upright board 51 and the window frame 55, resisting the elasticity force of belt spring 57 and being held standing upright. The sending device D can be embodied like the first embodiment shown in the use posture in Fig. 1 or as another device having a similar function. In Fig. 10 and 11, the freeing device F for bringing or putting a part of the note bunch in case C into the state of receiving no pressure is shown. The chain-dotted lines indicate another position of parts of the freeing device as explained later. In the back bottom part (lower right side in Fig. 10), an electric motor 61 which can rotate positively and reversely is set. This electric motor 61 drives a gear 62 through a gearbox. On both ends of a long axis of this gear 62, one of a pair of small rollers 63 is arranged by means of a crank, i.e. at the right and left ends thereof. A plate of a pistol-like shape shown in the center of Fig. 10 is one of a pair of operation boards 65. These operation boards 65 can be reciprocated in the horizontal direction in Fig. 10 (i.e back and forth in the apparatus) by moving the small rollers 63 inserted into a vertical long hole thereof An elongated stick shown in the center of Fig. 10 is one of a pair of operation rods 66 fixed to the center of the operation boards 65, respectively. On each operation rod 66, four long and slender claw plates 67 are mounted at almost equal intervals. Incidentally, a fingernail-shaped member 69 for enganging into the note bunch is formed at the end of each claw plate 67 near the sending device D (see Figl 1). At both ends of each claw plate 67, horizontally extending L-shaped long holes 60 are formed, respectively. At the center part thereof, a vertically extending long hole is formed for penetrating therethrough the operation rod 66. Near each of the claw plates 67 a long and slender guide body 64 is formed. These guide bodies 64 are fixed to the frame of the apparatus, respectively. A couple of screws 68 inserted in the L-shaped holes 60 of each of the claw plates 67 are fixed to the corresponding guide bodies 64. Each claw plate 67 is guided by the screws 68 inserted in the L-shaped holes 60. That is, when the pair of operation boards 65 is moved to the the front of the apparatus (to left in Fig. 10), the claw plates 67 on both sides approach mutually a little and are moved left (see as well Fig. 11). Therefore, the notes B in case C will be divided by the plurality of fingernail-shaped members 69. In other words, the notes B1 farther away from the open mouth M of sending device D are pressed by the fingernail-shaped members 69, and the notes B nearer to the open mouth M come into a free state without pressure, i.e. are not pressed by the notes B1 toward open mouth M. As in the first embodiment, a control device (not shown) is connected to and controls the operation of the means and devices of the apparatus. Two operation modes of the the second embodiment are explained in the following in an outline. In this embodiment which has the above-mentioned structure, a lot of notes B, for instance 1000 yen bills, are arranged upright in the case C (see Fig. 9). That is, opening (drawing away from the window frame) the upright board 51 resisting the elasticity force of belt spring 57, notes B are set upright and arranged in order in the resulting space between board 51 and window frame 55. After this, the case C is put into the apparatus and the distribution or dispensing of 1000 yen notes B can start. In other words, a lot of notes B are arranged vertically upright and in order in front of the open mouth M through window frame 55 (see Fig. 1). In the first operation mode, the freeing device F is not considered. Therefore, the bunch of notes B is slightly pressed toward the open mouth M. Thus, when the fan devices 23 and 24 are driven, as a result a negative pressure is caused at the open mouth M and the first note B bunch is adsorbed at this open mouth M, as described in the first embodiment. Then, the top part of first note B sent toward above, as desrcribed in the first embodiment, is placed between the rollers (see 71 in Fig. 7A). As a result, the first note B is compulsorily drawn up in the direction of the arrow. The bottom end of first note B which is drawn up passes through the lower part of open mouth M. At this time, this passage is detected by a pair of optical sensors (see S7 in Fig. 7A), and in reaction thereto the electric motor 25 is reversely rotated, sa decribed in the first embodiment. Thus, the first note B sent toward above is surely sent in the direction of the arrow. By the reverse run of belt 38, the second note B is prevented from being missent or moved in company to the upper side. In the second operation mode, the freeing device F is considered. First of all, when there is a start signal for distributing or dispensing notes B, the fan devices 23 and 24 are driven for preparation and the electric motors 61 and 70 are driven. When the electric motor 61 is positively rotated, the operation boards 65 are moved toward the front of the apparatus (left in Fig. 7A and 10) and the plurality of claw plates 67 are moved left through the operation rods 66 (see Fig. 10 and 11). As a result, the notes B farther away from the sending device D are held by the fingernail-shaped members 69, and the notes B closer to the device D get in the free state without pressure. On the other hand, when the electric motor 61 is positively rotated, a crank mechanism 91 is driven through pulleys and a long belt 60 (see the lower side of Fig. 8). When the crank mechanism 91 is driven, a long link 90 is moved and a guide piece 92 is once risen and stopped at a storing position as shown by a one-point-chain line. That is, the guide piece 92 closes the exit of storing room R (see the upper right part of Fig. 8). In other words, the rotation movement of crank mechanism 91 is converted into the vertical movement of guide piece 92 through the link 90. Further, a usual standby position of guide piece 92 is the same as the storing position shown by the one-point-chain line. The above-mentioned condition is detected by a projection 99 and a sensor pair S3 of operation board 65 (see the left part in Fig. 8). On the other hand, an electric motor 70 of direct current type is set on the upper part of this device. This electric motor 70 drives sending roller pairs 71 and 72 and long belt 73 through a gear train. The speed of driven sending rollers pair 71 and 72 and belt 73 is detected with a speed sensor S5. It is detected when the speed becomes constant. By detecting this speed with sensor S5, the preparation for the note distribution is completed. At this preparation and when the electric motor 25 of step type receives a note sending-out signal for a first note, the belt 38 is run positively and the first note B is sent up. When the first note B sent up is placed between the sending roller pair 71 and is sent further up, the note B concerned is detected by optical sensor pair S7. When the first note B is detected by the sensor pair S7, the electric motor 25 is controlled to reversely rotate in reaction to this detection signal. Thus, the belt 38 is run in the opposite direction and the second note B is prevented from being missend by the movement of the first note B. Further, the sensor S7 is detecting whether the first note B is actually only one note or whether plural notes are sent up as the first note. The note B sent up is guided and directed toward the front side of the apparatus (to the right in Fig. 8) by the second sending roller pair 72. When the passage of note B sent to the right in Fig. 8 is detected by sensor pair S6, the electric motor 25 is stopped and prepared for the following operation. When the electric motor 25 receives a second (or a further) sending signal for a note B, the belt 38 is controlled to run toward above and a second (or further) note B is sent up. In this manner, a desired number of notes B are stored in the storing room R. When the fixed number of notes are stored in the storing room R, the electric motor 61 is controlled to positively rotate further in reaction to the note distributing signal. When the electric motor 61 positively rotates, the guide piece 92 sinks and moves to position indicated by a solid line opening the exit of storing room R. This state is detected by the projection 99 and sensor pair S2 of operation board 65 (see the left part in Fig. 8). When the projection 99 is detected by the sensor pair S2, the electric motor 70 is stopped, and a solenoid for distribution (not shown) is driven at the same time. When a roller 97 is pressed by means of the solenoid to the belt 73 which is run according to inertia force, the notes B will be sent to the exit room E. When the notes B sent to the exit room E are taken out by hand, the distribution is confirmed by optical sensor pair S9. When the distribution of the notes is confirmed, the electric motor 61 is positively rotated further, and the projection 99 is detected by the optical sensor pair S1. When the sensor pair S1 confirms the projection 99, the electric motor 61 is stopped and returned to the state of standby, and the fan devices 23 and 24 are stopped in the state of standby. Therefore, the guide piece 92 will be at the position shown by the one-dot chain line, that is, the piece 92 closes the exit of storing room R. Of course, the couple of the freeing devices F will be returned to the former standby position, too. If it is detected with the optical sensor S7 that the number of notes B is, for instance, two, the electric motor 61 is reversely rotated. When the electric motor 61 is reversely rotated, the guide piece 92 moves up and comes to the position shownby the two-dots chain line. At the same time, the projection 99 is detected by the optical sensor pair S2. When the sensor pair S2 confirms the projection 99, the electric motor 61 is stopped and the solenoid (not shown) for distribution is driven and then the running belt 73 is pressed by the rollers 97. As a result, the notes B of storing room R are guided by the guide piece 92 moved up and are sent into the collection room 54. When the notes B of storing room R are sent to the collection room 54, the passage of notes B is detected by the sensor pair S9. When the passage of notes B is confirmed, the electric motor 61 is rotated positively and prepared for distribution of notes B, as mentioned above. As well in this second embodiment all modifications and so on mentioned with respect to the first embodiment can be employed. In other words, of course the apparatus can be used in spite of the positioning of the mouth M of the device D up or below or slanted. In this case, it can be of course necessary that other devices, for instance the case C and/or the freeing device F, are adapted. Of course other modifications are possible as well. For instance, it is preferable that the claw plate 67 of freeing device F is made of resin. Also, of course the number of claw plates 67 may be three. Additionally to the effects of the first embodiment already mentioned above, this embodiment provides a dispensing apparatus with a small and simple structure capable of surely and speedily counting notes one by one and then discharging (dispensing) them surely and savely.
