Description

Technical Field

[0001] The present invention relates to a media conveyance structure and a media handling device.

Background Art

[0002] Media handling devices for handling media such as banknotes are known (see Patent Document 1). Examples of media handling devices include those installed in financial institutions and those installed at the cash desks of retail stores. When installed at the cash desk of a retail store, for example, it is configured as a device (cash register coin machine) combined with a register unit or a coin processing device.

[0003] The media handling device includes a media conveyance structure for conveying media (e.g., banknotes).

Summary of the Invention

Problems to be Solved by the Invention

[0005] Let's consider a case where the transport path consists of two units. To remove jams, one unit is rotatable relative to the other. In this case, the number of parts that must pass through to position the transport guide increases, which presents a problem as the misalignment of the transport guide tends to become larger.

[0006] If the misalignment of the transport guides becomes significant, problems like those shown in Figure 16 can occur. For example, as shown in Figure 16(a), if the width of the transport path (the width between transport guides 811 and 821) widens beyond the appropriate width, the entry angle to the transport rollers 812 and 822 worsens, causing the medium B to collide with the transport roller 812 and resulting in a transport jam. Also, as shown in Figure 16(b), if the width of the transport path narrows beyond the appropriate width, a step is created between adjacent transport guides in the transport direction, causing the medium B to collide with this step and resulting in a transport jam. Furthermore, as shown in Figure 16(c), if tension is applied to the transport roller 812, if the width of the transport path widens beyond the appropriate width, variations in the tension of the transport roller 812 may occur, making it impossible to achieve the roller tension necessary for transporting the medium B.

[0007] The present invention has been made in view of the above-mentioned problems, and provides a media transport structure and media handling device that can suppress transport failures when the transport path is composed of two units. [Means for solving the problem]

[0008] To solve the aforementioned problems, a media transport structure according to one aspect of the present invention is a media transport structure provided in a device for transporting a medium, comprising: a pair of transport guides forming both sides of a transport path for transporting the medium; a pair of transport rollers arranged opposite each of the transport guides and transporting the medium in the transport path by rotating; and an elastic member connected to one of the first transport rollers, wherein one first transport guide and the other second transport guide are installed in two adjacent units, and the first transport roller is abutted against the other second transport roller by the elastic force of the elastic member. Furthermore, the system is equipped with two sets of the combination of the first conveyor roller and shaft, where the shaft of one set is fixed to the first conveyor guide, and the shaft of the other set is not fixed to the first conveyor guide, so that the first conveyor guide and the first conveyor roller of one set move together, and the first conveyor roller of the other set can move independently of the first conveyor guide.It is characterized by the following:

Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Each figure is only schematically shown to such an extent that the present invention can be sufficiently understood. Therefore, the present invention is not limited only to the illustrated examples. Also, in the drawings to be referred to, the dimensions of the members constituting the present invention may be exaggerated or otherwise expressed for the sake of clarity of explanation. In each figure, common components and similar components are denoted by the same reference numerals, and redundant explanations thereof are omitted. ​​​​​​​​​​​​As shown in Figure 1, the media handling device 1 mainly comprises a deposit unit 2 and a transport unit 3. The deposit unit 2 has a deposit / discharge slot 2a into which banknotes are inserted and discharged, and mainly performs processing related to deposits and withdrawals. The transport unit 3 is located adjacent to the rear of the deposit unit 2 and handles the exchange of banknotes between the deposit unit 2 and the transport unit 3. The transport unit 3 has, for example, a banknote storage compartment (not shown), and transports the deposited banknotes to the storage compartment for storage. The deposit unit 2 is an example of a "first unit," and the transport unit 3 is an example of a "second unit."

[0015] As shown in Figure 1, the deposit unit 2 and the transport unit 3 are covered by a cover 4. Although not shown in Figure 1, a frame 5 (see Figure 2) is located inside the cover 4, and the deposit unit 2 and the transport unit 3 are installed inside the media handling device 1 by the frame 5. The cover 4 is made of, for example, resin, and the frame 5 is made of, for example, metal. As shown in Figure 2, the frame 5 includes a frame 5a on the deposit unit 2 side, a frame 5b on the transport unit 3 side, and a frame 5c that connects the deposit unit 2 and the transport unit 3.

[0016] As shown in Figure 2, the deposit unit 2 is rotatable in the α1 and α2 directions around a pivot axis P located at the front lower part. In this embodiment, the pivot axis P is parallel to the line segment in the left-right direction (it coincides with the left-right direction). Rotation in the α1 direction moves the deposit unit 2 away from the transport unit 3, while rotation in the α2 direction moves the deposit unit 2 closer to the transport unit 3.

[0017] The media handling device 1 has an alignment structure 90 for aligning the deposit unit 2 with the transport unit 3 (see Figure 2). The alignment structure 90 consists of a protrusion 91 on the deposit unit 2 side and a protrusion 92 on the transport unit 3 side. The alignment structure 90 is provided on both the left and right sides of the media handling device 1. The protrusion 91 is a part that protrudes to the left or right (see Figure 3), and the protrusion 92 is a part that protrudes forward. When the deposit unit 2 is closed by rotating it in the α2 direction, the protrusion 91 rests on the protrusion 92. In other words, the protrusion 92 acts as a support and supports the weight of the deposit unit 2. The media handling device 1 can perform media handling processing with the deposit unit 2 closed, for example, the deposit unit 2 can be opened during maintenance.

[0018] As shown in Figure 2, the boundary between the deposit unit 2 and the transport unit 3 is sometimes referred to as the "boundary surface Q". The boundary surface Q does not need to be a flat surface; it may have irregularities. In this embodiment, the boundary surface Q is parallel to the plane composed of the top, bottom, left, and right. The pivot axis P is parallel to the boundary surface Q.

[0019] As shown in Figure 4, the media handling device 1 has a transport path K inside. The transport path K is a space for transporting banknotes and is formed between a pair of opposing transport guides. The transport path K is provided so as to connect the components of the media handling device 1 and may branch. Hereinafter, the path through which the media moves within the transport path K will be referred to as the "transport route R". In Figure 4, the transport route R in the deposit process is shown by a thick arrow. The media handling device 1 includes, for example, a transport route R1 for taking in deposited banknotes, a transport route R2 connected to transport route R1 for transporting banknotes upwards, and a transport route R3 connected to transport route R2 for transporting banknotes backwards.

[0020] In this embodiment, we will focus on the transport route R2 and describe the media transport structure 100 that realizes the transport route R2. The media transport structure 100 is a mechanism for transporting media and is provided near the interface Q (see Figure 2) between the deposit unit 2 and the transport unit 3. The media transport structure 100 transports the media in the vertical direction along the interface Q. The media transport structure 100 is separable, and the transport path K is opened by rotating the deposit unit 2 in the direction α1 away from the transport unit 3.

[0021] As shown in Figure 4, the media transport structure 100 mainly comprises a deposit unit side mechanism 10 located on the deposit unit 2 side and a transport unit side mechanism 20 located on the transport unit 3 side. The deposit unit side mechanism 10 mainly comprises a first transport guide 11, two sets of first transport rollers 12 arranged side by side in the vertical direction, and an elastic member 14. The transport unit side mechanism 20 mainly comprises a second transport guide 21 and two sets of second transport rollers 22 arranged side by side in the vertical direction.

[0022] As shown in Figure 4, the first transport guide 11 and the second transport guide 21 are positioned opposite each other, forming both sides of the transport path K that transports the banknotes. For this reason, the first transport guide 11 and the second transport guide 21 are sometimes collectively referred to as a "pair of transport guides." In addition, the first transport roller 12 and the second transport roller 22 of each pair are positioned opposite each other, making it possible to grip the banknotes from both sides. The first transport roller 12 and the second transport roller 22 transport the banknotes in the transport path K by rotating while gripping them. For this reason, the first transport roller 12 and the second transport roller 22 are sometimes collectively referred to as a "pair of transport rollers." In this embodiment, there are two pairs of transport rollers 12 and 22 arranged vertically, but the number of transport rollers 12 and 22 is not particularly limited and may consist of more than one or two pairs.

[0023] The second transport guide 21 of the transport unit side mechanism 20 is fixed to the frame 5b on the transport unit 3 side. Each set of second transport rollers 22 is fixed to a shaft 23 arranged in the left-right direction. Bearings (not shown) are pivotally supported near both ends of the shaft 23, and the bearings are supported by the frame 5b. Both the shaft 23 and the second transport rollers 22 are designed to rotate. The second transport rollers 22 are positioned opposite the first transport rollers 12 (i.e., they are arranged side by side in the left-right direction). In this embodiment, the transport unit side mechanism 20 has a total of four second transport rollers 22.

[0024] In this configuration, the positions of the second transport guide 21, second transport roller 22, and shaft 23 of the transport unit mechanism 20 are fixed and do not change when transporting banknotes, for example. On the other hand, the positions of the first transport guide 11, first transport roller 12, and shaft 13 of the deposit unit mechanism 10 according to this embodiment are not fixed but movable, and these components are configured to move together as a single unit. Therefore, when transporting banknotes, for example, the positions are changed within an acceptable range.

[0025] The configuration of the deposit unit side mechanism 10 will be explained with reference to Figures 5 to 9 (and Figures 1 to 4 as appropriate). As shown in Figure 5, the first transport guide 11 has grooves formed on the transport surface 11a side that are aligned horizontally and vertically, and the first transport roller 12 is housed in a specific groove. As shown in Figure 7, a part of the first transport roller 12 protrudes rearward from the first transport guide 11. As shown in Figure 6, a mounting frame 15 is installed on the back side (front side) relative to the transport surface 11a. The mounting frame 15 is a component for attaching the first transport guide 11 to the frame 5a on the deposit unit 2 side (see Figure 4). The first transport guide 11 is movable in the front-rear direction relative to the mounting frame 15.

[0026] As shown in Figure 6, the mounting frame 15 has holes 15a used for fixing it to the frame 5a on the deposit unit 2 side (see Figure 4). The mounting frame 15 also has three holes 15b for supporting the first transport guide 11. Three hook-shaped projections 11b are formed on the back side of the first transport guide 11, and the projections 11b are inserted into the holes 15b to prevent the first transport guide 11 from falling (detaching) from the mounting frame 15. The projections 11b also act as limiters that restrict the movement of the first transport guide 11 by the elastic member 14 when the transport path K is open (details will be described later). Therefore, the holes 15b of the mounting frame 15 and the projections 11b of the first transport guide 11 are an example of a "limiter structure".

[0027] As shown in Figure 8, each set of first conveyor rollers 12 is pivotally supported on a shaft 13 arranged in the left-right direction. The shaft 13, acting as an axis, is fixed to the first conveyor guide 11 and is prevented from rotating together with the first conveyor rollers 12. Each set of first conveyor rollers 12 is positioned far apart from both ends of the shaft 13 (i.e., they are arranged side by side in the left-right direction). As shown in Figure 8, the deposit unit side mechanism 10 has a total of four first conveyor rollers 12.

[0028] As shown in Figure 7, the elastic member 14 is installed between the first transport guide 11 and the mounting frame 15. As shown in Figure 8, the elastic member 14 in this embodiment is a double torsion spring, and has the shape of two torsion coil springs joined together (having two coil portions 14a). The elastic member 14 has its end portion 14b in contact with the lower shaft 13, and its joint portion 14c in contact with the upper shaft 13. The elastic member 14 is positioned with a load applied to the coil portion 14a (the coil portion 14a is rotating due to bending stress), and generates a force (elastic force) that pushes the shaft 13 backward (towards the transport unit 3) (that is, tension is applied in the direction of the transport unit 3).

[0029] With this configuration, as shown in Figure 4, when the deposit unit 2 is closed, the first transport roller 12 on the deposit unit 2 side abuts against the second transport roller 22 on the transport unit 3 side. In other words, the elastic force of the elastic member 14 connected to the first transport roller 12 via the shaft 13 causes the first transport roller 12 to abut against the second transport roller 22. To put it another way, the first transport roller 12 is pressed against the second transport roller 22 even further than when it was in contact with it. The contact between the first transport roller 12 and the second transport roller 22 causes the distance from the first transport guide 11 to the second transport guide 21 (i.e., the width of the transport path K) to be set to a predetermined value (a value suitable for transport).

[0030] (Limiter structure to prevent detachment) As shown in Figure 2, when the deposit unit 2 is open, there is nothing for the first conveyor roller 12 to abut against, so the force of the elastic member 14 causes the first conveyor guide 11 to move in the β1 direction more than when the deposit unit 2 is closed. When the first conveyor guide 11 has moved a predetermined amount in the β1 direction, the projection 11b shown in Figure 6 catches on the mounting frame 15, and the first conveyor guide 11 becomes locked. In other words, even when the deposit unit 2 is open, the structure prevents the first conveyor guide 11 from moving more than a certain distance away from the mounting frame 15. When the deposit unit 2 is closed, a gap is formed between the projection 11b and the mounting frame 15. In other words, the limiter structure does not hinder the first conveyor roller 12 from abutting against the second conveyor roller 22.

[0031] (Vertical positioning structure: "First directional movement restricting structure") As shown in Figure 8, the left and right ends of the first transport guide 11 have protrusions 11c that project in either the left or right direction. Also, as shown in Figure 3, the frame 5a on the deposit unit 2 side has guide grooves 5aa formed at positions corresponding to the protrusions 11c (a roughly U-shaped member in Figure 3). The front-rear dimension of the guide groove 5aa is larger than the front-rear dimension of the protrusion 11c, so the first transport guide 11 can move in the front-rear direction when the protrusion 11c is inserted into the guide groove 5aa. On the other hand, the vertical dimension of the guide groove 5aa is the same as (or slightly larger than) the vertical dimension of the protrusion 11c, so the first transport guide 11 cannot move in the vertical direction when the protrusion 11c is inserted into the guide groove 5aa. In other words, the movement of the first transport guide 11 is restricted in the vertical direction. The vertical direction is an example of a direction (first direction) that is perpendicular to the pivot axis P shown in Figure 2 and parallel to the interface surface Q. As a result, the first conveyor roller 12 on the deposit unit 2 side abuts against the second conveyor roller 22 on the conveyor unit 3 side without any vertical displacement.

[0032] (Left-right positioning structure: "Second-direction movement restricting structure") As shown in Figure 9, the inner portion of the first transport guide 11 where the protruding portion 11c is formed has a convex portion 11d that protrudes in either the left or right direction. In addition, the mounting frame 15 has a component at a position corresponding to the convex portion 11d. The shape and size of the convex portion 11d do not need to be such as to fill the gap between the first transport guide 11 and the mounting frame 15, and there is no limit to the number of convex portions. Because the gap between the first transport guide 11 and the mounting frame 15 is filled by the convex portion 11d, the first transport guide 11 cannot move in the left or right direction (or the amount of movement is extremely small). In other words, the movement of the first transport guide 11 in the left or right direction is restricted. The left or right direction is an example of a direction parallel to the rotation axis P shown in Figure 2 (second direction). As a result, the first transport roller 12 on the deposit unit 2 side abuts against the second transport roller 22 on the transport unit 3 side without any displacement in the left or right direction.

[0033] As described above, according to the media transport structure 100 and the media handling device 1 equipped with the media transport structure 100 according to the first embodiment, when the deposit unit 2 is closed, the first transport roller 12 on the deposit unit 2 side abuts against the second transport roller 22 on the transport unit 3 side, thereby determining the position of the first transport guide 11 fixed to the first transport roller 12. In other words, the position of the first transport guide 11 is determined in accordance with the position of the first transport roller 12, so that the variation in positional deviation is minimized.

[0034] [Second Embodiment] In the first embodiment, since the shafts 13 and 23 were fixed to the transport guides 11 and 21, the tilt of the shafts of the transport rollers 12 and 22 depended on the component precision of the transport guides 11 and 21. In other words, it is difficult to adjust only the tilt of the shafts of the transport rollers 12 and 22 independently of the transport guides 11 and 21. As a result, if the tilt of the shaft of the second transport roller 22 on the transport unit 3 side does not match the tilt of the shaft of the first transport roller 12 on the deposit unit 2 side, the second transport roller 22 and the first transport roller 12 may not make contact, or even if they do, they may not be able to produce sufficient roller tension. For example, as shown in Figure 10(a), if the shaft of the second transport roller 22 in the lower left is tilted, the second transport roller 22 and the first transport roller 12 may not make contact (resulting in three-point contact instead of four-point contact). As described above, when there are areas where the conveyor rollers 12 and 22 make contact with the surface and areas where they do not, a difference in the feed force of the conveyor rollers 12 and 22 occurs, and if the difference becomes large enough to be ignored, conveying defects such as skew will occur.

[0035] Therefore, as shown in Figure 10(b), the media transport structure 100A according to the second embodiment is designed so that the shaft 13 (axis) of one of the two sets of first transport rollers 12 arranged side by side in the vertical direction (in this case, the lower set of first transport rollers 12) can be tilted independently of the first transport guide 11. Specifically, the shape of the hole 11e formed in the first transport guide 11 through which the shaft 13 of the first transport roller 12 is inserted is made larger in the front-to-back direction (the direction in which the first transport roller 12 is pressed). The method for increasing the front-to-back dimension of the hole 11e is not limited and can be an elongated hole or a groove shape. For example, as shown in Figure 11, the front-to-back dimension L2 of the hole 11e through which the shaft 13 is inserted is made longer (an elongated hole) than the front-to-back dimension L1 of the shaft 13, so that the shaft 13 is tilted in the front-to-back direction. In this case, the amount of play in the elongated hole 11e should be greater than the assumed inclination of the axis, and should be such that no conveying failure occurs at the points where the media is transferred before and after the movable first conveying guide 11.

[0036] The media transport structure 100A according to the second embodiment described above can also achieve substantially the same effects as the first embodiment. Furthermore, according to the media transport structure 100A of the second embodiment, by making the hole 11e through which one shaft is inserted an elongated hole, the transport rollers 12 and 22 can make contact even if the shaft is tilted. As a result, the necessary feed force for transport can be generated, and the difference in feed force between the left and right transport rollers 12 and 22 can be minimized, thereby suppressing the occurrence of problems such as skew.

[0037] [Third Embodiment] In the first and second embodiments, the shafts 13 of both sets or one set are fixed to the first transport guide 12, so that the first transport guide 12 and at least one set of the first transport rollers 12 move together. Therefore, each time a medium passes over the first transport rollers 12 of the set to which the shafts 13 are fixed, the first transport guide 12 vibrates (moves) by the thickness of the medium. As a result, for example as shown in Figure 12, when a medium Bt that has undergone unintended deformation, such as a folded medium, passes over, a misalignment exceeding expectations occurs at the medium transfer section before and after the movable transport guide 11, and if the misalignment is large, the medium Bt may collide with a part other than the transport surface, resulting in a transport failure. Therefore, in the third embodiment, the structure is made so that the two sets of first transport rollers 12, which are arranged side by side in the vertical direction, can move in the front-rear direction independently of the first transport guide 11.

[0038] Specifically, as shown in Figure 13, the media transport structure 100B according to the third embodiment is provided with a stopper portion 11f on the first transport guide 11 on the deposit unit 2 side, and also with a corresponding stopper portion 21f on the second transport guide 21 on the transport unit 3 side. Furthermore, an elastic member 16 is installed between the first transport guide 11 and the mounting frame 15. The elastic member 16 here is, for example, a leaf spring and is positioned with a load applied. The elastic member 16 generates a force that pushes the first transport guide 11 backward (towards the transport unit 3) (i.e., tension is applied in the direction of the transport unit 3), pressing the stopper portion 11f on the deposit unit 2 side against the stopper portion 21f on the transport unit 3 side. In this case, the tension should be strong enough so that the first transport guide 11 does not move under the transport load of the media.

[0039] Furthermore, as shown in Figure 13, the portion of the first conveyor roller 12 through which the shaft 13 is inserted is a U-shaped groove 11g, allowing it to move in the direction of the opposing second conveyor roller 22 (front-to-back direction). The first conveyor roller 12 is tensioned towards the rear (towards the conveyor unit 3) by an elastic member 14. The "limiter structure" that prevents the first conveyor guide 11 from falling out is the same as in the first embodiment. With this structure, even when a medium passes through, the distance between the first conveyor guide 11 and the second conveyor guide 21 remains unchanged, and only the first conveyor roller 12 is pushed forward by the thickness of the medium.

[0040] The media transport structure 100B according to the third embodiment described above can also achieve substantially the same effects as the second embodiment. Specifically, the position of the first transport guide 11 is determined by the position of the second transport guide 21, resulting in minimal variation. Furthermore, since the axis of the first conveyor roller 12 is movable in the pressing direction (front-to-back direction), it is possible to prevent the first conveyor roller 12 from lifting off the second conveyor roller 22. Furthermore, by pressing the first transport guide 11 and the first transport roller 12 with other elastic members (elastic members 14, 16), the movement of the first transport roller 12 does not affect the first transport guide 11. As a result, when a medium Bt that has undergone unintended deformation, such as a folded medium, passes through, no misalignment occurs at the medium transfer section before and after the first transport guide 11.

[0041] Although embodiments of the present invention have been described above, the present invention is not limited thereto and can be implemented without changing the spirit of the claims. In each embodiment, the banknote processing device shown in Figure 1 was assumed to be a device equipped with the media transport structures 100, 100A, and 100B. However, the devices to which the media transport structures 100, 100A, and 100B according to each embodiment can be applied are not limited to banknote processing devices, but can be used in various devices that handle media. For example, the media transport structures 100, 100A, and 100B according to each embodiment can be used in the coin handling device 1001 shown in Figure 14. The coin handling device 1001 shown in Figure 14 includes a banknote processing unit 1002 for processing banknotes and a coin processing unit 1003 for processing coins.
