A gravity inclined wheel type vertical ticket feeding automatic deviation correction structure

Abstract

An automatic vertical ticket feeding and correction structure with gravity-driven inclined wheel includes an active correction component, a passive correction component, and a ticket feeding mechanism. The ticket feeding mechanism has a correction channel for ticket passage. Within the correction channel, between the ticket inlet and outlet, are the active and passive correction components. The active correction component includes a rubber wheel driven to rotate by a power mechanism. The passive correction component includes a driven wheel that matches the rubber wheel. The rubber wheel and driven wheel are symmetrically positioned on both sides of the correction channel, abutting against each other. An angle is formed between the rotation plane of the rubber wheel and driven wheel and the channel floor plate. This angle allows the rubber wheel and driven wheel to exert a correction force perpendicular to the channel floor plate and a paper-feeding force parallel to the channel floor plate on the ticket entering the correction channel. This invention ensures that the ticket completes the correction process within the correction channel, enabling the ticket to stably enter subsequent processes, significantly reducing the failure rate and improving customer experience.

Description

Technical Field

[0001] This invention relates to a gravity-driven inclined wheel type automatic ticket feeding correction structure. Background Technology

[0002] One function of self-service financial equipment is to receive and scan, verify, and print financial documents. Although the technologies for scanning, verifying, and printing financial documents are very mature, these functions are highly dependent on the accuracy of document feeding. If the error in document feeding exceeds a predetermined value, it will increase the error rate of subsequent scanning, verification, and printing. Therefore, when using the equipment, users should try to ensure that the document is level with the feeding slot and is inserted straight and stably along the feeding direction to prevent the document from tilting as it enters the document channel. However, on the one hand, due to the wide variety of document types, sizes, and thicknesses, and on the other hand, due to different customer feeding habits, it is impossible to control them uniformly. This often results in documents being inserted inaccurately, causing subsequent scanning, verification, and printing failures, thus reducing the customer's overall experience with the equipment. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a gravity-driven inclined wheel-type automatic correction structure for vertical ticket entry that can correct and align tickets at any entry angle.

[0004] To achieve the above objectives, this invention first proposes a gravity-driven inclined wheel type vertical ticket feeding automatic correction structure, including a correction active component, a correction passive component, and a ticket feeding mechanism. The ticket feeding mechanism is provided with a correction channel for ticket passage. The correction active component and the correction passive component are arranged within the correction channel, between the ticket inlet and the ticket outlet. The correction active component includes a rubber wheel driven to rotate by a power mechanism. The correction passive component includes a driven wheel that matches the rubber wheel. The rubber wheel and the driven wheel are symmetrically placed on both sides of the correction channel and abut against each other. The rotation plane of the rubber wheel and the driven wheel is at an angle with the bottom plate of the channel. The angle allows the rubber wheel and the driven wheel to exert a correction force perpendicular to the bottom plate and a paper feeding force parallel to the bottom plate on the ticket entering the correction channel.

[0005] With the above structure, after the bill is inserted into the correction channel, under the action of the paper feeding force, the bill moves from the inlet to the outlet. Under the action of the correction force, the bill moves towards the bottom plate of the channel. During the process of the bill moving from the inlet to the outlet in the correction channel, the correction force moves the bill towards the bottom plate of the channel, so that the bottom edge of the bill exiting the outlet is always in contact with the bottom plate of the channel. The bottom plate of the channel is used as a reference to achieve the correction of the bill. In this way, no matter what angle the bill makes with the bottom plate of the channel after entering from the inlet, under the action of the correction force, the bottom edge of the bill will always abut against the bottom plate of the channel when it exits from the outlet, thus achieving the purpose of correction and alignment at any inlet angle.

[0006] In this embodiment, the ticket feeding mechanism includes a left channel plate, a right channel plate, and a channel bottom plate. The left and right channel plates are fixed parallel to each other on the channel bottom plate, and a gap is provided between the left and right channel plates to form the correction channel. A paper detection sensor module is provided at the ticket inlet of the correction channel to detect whether the paper is inserted. A paper output device is provided at the paper outlet of the correction channel to guide the ticket to the next step. The correction active component includes a bearing seat, a second power shaft, a second bearing, a rubber wheel, a universal joint coupling, a first power shaft, and a first bearing. The bearing seat is fixed on the outer side of the left channel plate. The second bearing is installed on the bearing seat. One end of the second power shaft is installed on the second bearing, and the other end is fixed on one end of the universal joint coupling. The other end of the universal joint coupling is connected to the power mechanism through the first power shaft. The rubber wheel is coaxially fixed on the second power shaft and linked with the second power shaft. A through groove is provided on the left channel plate at the location of the rubber wheel for the rubber wheel to pass through. The first power shaft is vertically arranged and fixed to the left channel plate through the first bearing. The power mechanism transmits power to the second power shaft through the first power shaft and the universal joint coupling, thereby driving the rubber wheel to rotate. The purpose of the universal joint coupling is to facilitate the adjustment of the tilt angle of the second power shaft, thereby achieving the purpose of adjusting the angle between the rubber wheel and the horizontal plane.

[0007] In this embodiment, the bearing housing is L-shaped, with multiple first fixing holes on its vertical portion. Multiple sets of first adjusting screw holes are provided on the outer side of the left side plate of the channel. These sets are evenly distributed along the rotation path of the universal joint coupling. Each set includes multiple first adjusting screw holes that match the first fixing holes on the bearing housing. A through slot is provided on the left side plate of the channel at a position corresponding to each set of first adjusting screw holes. The bearing housing is fixed to the first adjusting screw holes on the left side plate of the channel by first screws passing through the first fixing holes, thus fixing the bearing housing to the left side plate of the channel. Simultaneously, the rubber wheel enters the correction channel through the through slot. The multiple sets of first adjusting screw holes on the left side plate of the channel are provided to facilitate adjustment of the bearing housing's installation position as needed.

[0008] In this embodiment, the passive correction component includes a fixed shaft, a spring, an adjusting plate, a driven wheel, a fixed plate, and adjusting screws. The fixed plate has multiple second fixing holes, and the outer side of the right side plate of the channel has multiple sets of second adjusting screw holes corresponding to the first adjusting screw hole sets. Each set of first adjusting screw holes includes multiple second adjusting screw holes that match the second fixing holes on the fixed plate. The fixed plate is fixed to the second adjusting screw hole sets of the right side plate of the channel by second screws passing through the second fixing holes, thus fixing the fixed plate to the right side plate of the channel. The purpose of providing multiple sets of second adjusting screw hole sets on the right side plate of the channel is to facilitate the adjustment of the fixed plate's installation position as needed, thereby achieving the driven wheel... The corresponding adjustment of the wheel and rubber wheel positions: the driven wheel is mounted on the fixed shaft through a bearing, and a spring is fixed at each end of the fixed shaft; the fixed plate has a threaded hole that matches the position of the spring, and an adjusting screw is installed in the threaded hole of the fixed plate; an adjusting groove is opened on the right side plate of the channel at the position corresponding to the adjusting screw, and the shape of the adjusting groove matches the layout path of multiple sets of second adjusting screw holes on the right side plate of the channel; the end of the adjusting screw is inserted into the adjusting groove, and the end of the adjusting screw passes through the adjusting groove and is fixed with an adjusting plate; the adjusting plate is fixedly connected to the other end of the spring, so that both ends of the fixed shaft are connected to the adjusting plate through the spring.

[0009] With the above structure, a preload is applied to the fixed shaft by a spring, so that there is an initial pressure between the driven wheel and the rubber wheel. The preload can be adjusted by rotating the adjusting screw. On the one hand, it can ensure that the clamping force between the driven wheel and the rubber wheel is sufficient to drive the paper to feed, and also ensure that the friction force between the driven wheel and the rubber wheel on the paper is within a suitable range after the paper comes into contact with the bottom plate of the channel, so that the paper will not be squeezed and deformed. On the other hand, the preload can also be adjusted to accommodate paper of different thicknesses.

[0010] In this embodiment, the inner side of the right side plate of the channel is provided with multiple sets of limiting grooves that match the fixed shaft and multiple sets of movable grooves that match the driven wheel. Each set of second adjusting screw holes is equipped with a set of limiting grooves and movable grooves. The limiting grooves are used to limit the fixed shaft and prevent it from rotating when adjusting the preload. The movable grooves are used to provide rotation space for the driven wheel. Through multiple sets of limiting grooves and movable grooves, when the driven wheel is adjusted according to the position of the rubber wheel, the fixed shaft and the driven wheel still have corresponding installation positions.

[0011] In this embodiment, the paper detection sensing module includes a transmitting sensor disposed on the left side plate of the channel and a receiving sensor disposed on the right side plate of the channel. The transmitting sensor and the receiving sensor are arranged opposite to each other. The transmitting sensor and the receiving sensor are electrically connected to the controller. The controller is electrically connected to the power mechanism and controls the opening and closing of the power mechanism.

[0012] In this embodiment, let the height of the correction channel be a, the width of the ticket be b, the shortest distance from the center of the rubber wheel to the ticket inlet be c, the angle between the bottom edge of the ticket and the bottom plate of the channel when the ticket enters be θ, and the angle between the rotation plane of the rubber wheel and the driven wheel and the bottom plate of the channel be α.

[0013] The shortest distance from the center of the rubber roller to the paper feed roller is d.

[0014] By linking the height 'a' of the correction channel, the width 'b' of the document, and the shortest distance 'd' from the center of the fixed rubber roller to the paper feed roller, the correction process of the document can be completed within the correction channel, ensuring that the document can stably enter subsequent processes, greatly reducing the failure rate and improving the customer experience.

[0015] In summary, after the bill is inserted into the correction channel, the paper feed force causes the bill to move from the inlet to the outlet. The correction force then moves the bill towards the channel floor. During this movement, the correction force propels the bill towards the channel floor, ensuring that the bottom edge of the bill exiting the outlet remains in contact with the floor. This allows for bill correction based on the floor. Thus, regardless of the angle between the bill and the floor after entry, the correction force ensures that the bottom edge of the bill always contacts the floor, achieving alignment at any entry angle.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0026] like Figures 1 to 7As shown: A gravity-driven inclined wheel type vertical ticket feeding automatic correction structure includes a correction active component 3, a correction passive component 6, a ticket feeding mechanism, and a paper detection sensor module. The ticket feeding mechanism has a correction channel 7 for ticket passage. The correction active component 3 and the correction passive component 6 are arranged within the correction channel 7, between the ticket inlet and the ticket outlet. The correction active component 3 includes a rubber wheel 34 driven to rotate by a power mechanism. The correction passive component 6 includes a driven wheel 64 that matches the rubber wheel 34. The rubber wheel 34 and the driven wheel 64 are symmetrically positioned on both sides of the correction channel 7, abutting against each other. The axles of the rubber wheel 34 and the driven wheel 64 are parallel to each other and parallel to the plane of the correction channel 7. An angle is formed between the axles of the rubber wheel 34 and the driven wheel 64 and the bottom plate 9 of the channel. This angle causes the rubber wheel 34... The driven wheel 64 provides a correction force perpendicular to the channel base plate 9 and a paper feeding force parallel to the channel base plate 9 to the ticket entering the correction channel 7. After the ticket is inserted into the correction channel 7, under the action of the paper feeding force, the ticket moves from the inlet to the outlet, and under the action of the correction force, the ticket moves towards the channel base plate 9. In this way, during the process of the ticket moving from the inlet to the outlet in the correction channel 7, the correction force drives the ticket to move towards the channel base plate 9, so that the bottom edge of the ticket exiting the outlet is always in contact with the channel base plate 9. The channel base plate 9 is used as a reference to achieve the correction of the ticket. In this way, no matter what angle the ticket makes with the channel base plate 9 after entering from the inlet, under the action of the correction force, the bottom edge of the ticket will always abut against the channel base plate 9 when it exits from the outlet, achieving the purpose of correction and alignment at any inlet angle.

[0027] Furthermore, the ticket feeding mechanism includes a left channel plate 1, a right channel plate 4, and a channel bottom plate 9. The left channel plate 1 and the right channel plate 4 are fixed parallel to each other on the channel bottom plate 9, and a gap is provided between the left channel plate 1 and the right channel plate 4 to form the correction channel 7. A paper detection sensor module for detecting whether paper is inserted is provided in the ticket feeding port of the correction channel 7, and a paper feeding roller 10 for exporting the ticket to the next process is provided in the paper output port of the correction channel 7.

[0028] like Figure 3As shown, the active correction assembly 3 includes a bearing housing 31, a second drive shaft 32, a second bearing 33, a rubber wheel 34, a universal joint coupling 35, a first drive shaft 36, and a first bearing 37. A bearing housing 31 is fixed to the outer side of the left side plate 1 of the passage. A second bearing 33 is installed on the bearing housing 31. One end of the second power shaft 32 is installed on the second bearing 33, and the other end is fixed to one end of the universal joint coupling 35. The other end of the universal joint coupling 35 is connected to the power mechanism through the first power shaft 36. The rubber wheel 34 is coaxially fixed on the second power shaft 32 and linked with the second power shaft 32. A through groove for the rubber wheel 34 to pass through is provided on the left side plate 1 of the passage at the location of the rubber wheel 34. The first power shaft 36 is vertically arranged and fixed to the left side plate 1 of the passage through the first bearing 37. The power mechanism transmits power to the second power shaft 32 through the first power shaft 36 and the universal joint coupling 35, thereby driving the rubber wheel 34 to rotate. The purpose of the universal joint coupling 35 is to facilitate the adjustment of the tilt angle of the second power shaft 32, thereby achieving the purpose of adjusting the angle between the rubber wheel 34 and the horizontal plane.

[0029] Furthermore, the bearing housing 31 is L-shaped, and the vertical part of the bearing housing 31 is provided with multiple first fixing holes. The outer side of the left side plate 1 of the channel is provided with multiple sets of first adjusting screw holes. The multiple sets of first adjusting screw holes are arranged along the rotation path of the universal joint coupling 35. Each set of first adjusting screw holes includes multiple first adjusting screw holes that match the first fixing holes on the bearing housing 31. The left side plate 1 of the channel is provided with a through groove at the position corresponding to each set of first adjusting screw holes. The bearing housing 31 is fixed in the first adjusting screw hole on the left side plate 1 of the channel by the first screw passing through the first fixing hole, thereby fixing the bearing housing 31 to the left side plate 1 of the channel. At the same time, the rubber wheel 34 enters the correction channel 7 through the through groove. With the setting of multiple sets of first adjusting screw holes, the deflection angle of the rubber wheel 34 is adjusted by the universal joint coupling 35. After the adjustment is completed, it is only necessary to fix the bearing housing 31 on the corresponding first adjusting screw hole set.

[0030] like Figure 3 As shown, the passive alignment component 6 includes a fixed shaft 61, a spring 62, an adjusting plate 63, a driven wheel 64, a fixed plate 65, and adjusting screws 66. The fixed plate 65 has multiple second fixing holes, and the outer side of the right side plate 4 of the channel has multiple sets of second adjusting screw holes corresponding to the first adjusting screw hole sets. Each set of first adjusting screw holes includes multiple second adjusting screw holes that match the second fixing holes on the fixed plate 65. The fixed plate 65 is fixed to the right side plate 4 of the channel by second screws passing through the second fixing holes, thus fixing the fixed plate 65 to the right side plate 4 of the channel. The purpose of providing multiple sets of second adjusting screw holes on the right side plate 4 of the channel is to facilitate the adjustment of the installation position of the fixed plate 65 as needed, thereby achieving the corresponding adjustment of the positions of the driven wheel 64 and the rubber wheel 34.

[0031] The driven wheel 64 is mounted on the fixed shaft 61 via bearings. A spring 62 is fixed to each end of the fixed shaft 61. A threaded hole matching the position of the spring 62 is provided on the fixed plate 65. An adjusting screw 66 is threaded into the threaded hole of the fixed plate 65. An adjusting groove is formed on the right side plate 4 of the channel, corresponding to the position of the adjusting screw 66. The shape of the adjusting groove matches the arrangement path of multiple sets of second adjusting screw holes on the right side plate 4 of the channel. The end of the adjusting screw 66 is inserted into the adjusting groove, passes through the adjusting groove, and is fixed to an adjusting plate 63. The adjusting plate 63 is fixedly connected to the other end of the spring 62, so that both ends of the fixed shaft 61 are connected to the adjusting plate 63 via the spring 62. The spring 62 provides a preload to the fixed shaft 61, creating an initial pressure between the driven wheel 64 and the rubber wheel 34. By rotating the adjusting screw 66, the preload can be adjusted according to the thickness of the document, allowing the device to adapt to documents of different thicknesses.

[0032] Furthermore, the inner side of the right side plate 4 of the channel is provided with multiple sets of limiting grooves that match the fixed shaft 61 and multiple sets of movable grooves that match the driven wheel 64. Each set of second adjusting screw holes is equipped with a set of limiting grooves and movable grooves. The limiting grooves are used to limit the fixed shaft 61 and prevent the fixed shaft 61 from rotating when adjusting the preload. The movable grooves are used to provide space for the rotation of the driven wheel 64. Through multiple sets of limiting grooves and movable grooves, when the driven wheel 64 is adjusted according to the position of the rubber wheel 34, the fixed shaft 61 and the driven wheel 64 still have corresponding installation positions.

[0033] The paper detection sensing module includes a transmitting sensor 2 set on the left side plate 1 of the channel and a receiving sensor 5 set on the right side plate 4 of the channel. The transmitting sensor 2 and the receiving sensor 5 are arranged opposite to each other. The transmitting sensor 2 and the receiving sensor 5 are electrically connected to the controller. The controller is electrically connected to the power mechanism. The controller controls the opening and closing of the power mechanism.

[0034] The specific working process of the above structure is as follows:

[0035] The ticket 8 is inserted into the ticket inlet and then into the correction channel 7. After the ticket 8 enters the ticket inlet, the transmitting sensor 2 and the receiving sensor 5 detect that the ticket 8 has entered. The controller sends a signal to the power mechanism, which starts and drives the first power shaft 36 to transmit power to the second power shaft 32, thereby driving the rubber wheel 34 to rotate and driving the driven wheel 64 to rotate. After the ticket enters the correction channel, it comes into contact with the rubber wheel 34 and the driven wheel 64 and is drawn into the correction channel by friction, thus achieving correction.

[0036] like Figure 4As shown, when the ticket 8 enters the correction channel at an upward tilt angle, the ticket 8 forms a fulcrum with the channel bottom plate 9. Under the action of the rubber wheel 34 and the driven wheel 64, the ticket 8 completes a rotational motion around the fulcrum O within the channel, forming... Figure 6 As shown, this ensures that the bottom edge of ticket 8 is in line contact with the bottom plate of the channel.

[0037] like Figure 5 As shown, when ticket 8 enters the correction channel at a downward angle, the front end of ticket 8 is clamped by the driven wheel 64 and the rubber wheel 34, while the rear end falls onto the channel floor plate 9 under the influence of gravity, thus becoming... Figure 4 The upward tilt angle of the ticket feeding method described above; here, it is necessary to ensure that the ticket 8 can be clamped by the driven wheel 64 and the rubber wheel 34, but the clamping force is not too large, so that the ticket will hit the bottom plate 9 of the channel under the action of the rubber wheel 34 and the driven wheel 64, causing the ticket to curl, bend, etc. At this time, it is necessary to adjust the preload of the spring 62 by rotating the adjusting screw 66 according to the thickness of different tickets, thereby adjusting the clamping force of the driven wheel 64 and the rubber wheel 34. In this embodiment, in order to ensure the correction effect, the pressure at the contact position between the driven wheel 64 and the rubber wheel 34 is 1.5N-2.5N for optimal results.

[0038] The specific dimensional design requirements for the correction channel 7 of this invention are as follows:

[0039] Let the height of the correction channel be *a*, the width of the ticket be *b*, the shortest distance from the center of the rubber roller to the ticket inlet be *c*, the angle between the bottom edge of the ticket and the bottom plate of the channel when the ticket enters be *θ*, the angle between the rotation plane of the rubber roller and the driven roller and the bottom plate of the channel be *α*, and the shortest distance from the center of the rubber roller 34 to the paper feed roller 10 be *d*.

[0040] When designing the correction channel 7, ensure that

[0041] By linking the height 'a' of the correction channel, the width 'b' of the document, and the shortest distance 'd' from the center of the fixed rubber roller to the paper feed roller, the correction process of the document can be completed within the correction channel, ensuring that the document can stably enter subsequent processes, greatly reducing the failure rate and improving the customer experience.

[0042] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
