Description

Technical Field

[0001] This invention relates to the field of sheet media processing, and more specifically, to a correction device, sheet media processing equipment, and a control method for the correction device. Background Technology

[0002] The related technology provides a correction device including a frame and a conveying channel, a drive mechanism, and a correction wheel disposed on the frame. A reference surface is provided in the conveying channel and is located on one side of the conveying channel along a direction perpendicular to the conveying direction of the sheet-like medium. The correction wheel is rotatably disposed on the frame and partially extends into the conveying channel. The axis of the correction wheel is set at an angle with the reference surface. Under the drive of the drive mechanism, the correction wheel can rotate around its own axis and drive the sheet-like medium in the conveying channel to move. The correction wheel exerts a first component force and a second component force on the sheet-like medium in the conveying channel. The first component force is used to push the sheet-like medium to move towards the reference surface; the second component force is used to push the sheet-like medium to move downstream of the conveying channel.

[0003] However, when the thin sheet-like medium is thin and soft, the first component force is insufficient, which may lead to the failure of the correction.

[0009] In an optional embodiment, the rotating element is a ball bearing, and the axis of the pivot shaft passes through the center of the ball bearing.

[0010] In an optional embodiment, the first drive mechanism includes a first motor and a drive gear. The first motor is mounted on the frame, and the drive gear is sleeved on the pivot shaft and drivenly connected to the output shaft of the first motor. The support frame is fixedly connected to the drive gear. The second drive mechanism includes a second motor mounted on the support frame, and the output shaft of the second motor is drivenly connected to the correction wheel for driving the correction wheel to rotate.

[0011] In an optional embodiment, the support frame includes a first plate and a second plate fixedly connected at an angle, a second motor fixedly connected to the first plate, and a drive gear fixedly connected to the second plate.

[0012] In an optional embodiment, the length direction of the conveying channel extends along the conveying direction of the sheet-like medium, and the reference plane is located on one side of the width direction of the conveying channel; the frame includes a first channel plate, a second channel plate, and a cover plate.

[0014] Secondly, embodiments of the present invention provide a sheet-like medium processing device, including a processing mechanism and a correction device according to any of the foregoing embodiments, wherein the correction device and the processing mechanism are arranged sequentially along the conveying direction of the sheet-like medium.

[0015] Thirdly, embodiments of the present invention provide a control method for a correction device as described in any of the foregoing embodiments, comprising:

[0016] Control the first drive mechanism to drive the support frame to rotate to the first position, so that the angle between the axis of the correction wheel and the reference plane is α;

[0017] The second drive mechanism is controlled to drive the correction wheel to rotate in the first direction, so that the correction wheel drives the sheet-like medium to approach the reference plane, and it is determined whether the sheet-like medium has been successfully corrected.

[0018] When it is determined that the correction of thin-film media is unsuccessful.

[0019] If the angle between the first side of the sheet-like medium and the reference plane is too large, causing the correction to fail, then the first drive mechanism is controlled to drive the support frame to rotate to the second position, so that the angle between the axis of the correction wheel and the reference plane is β, and β is less than α. Then the second drive mechanism is controlled to drive the correction wheel to rotate in the second direction opposite to the first direction, so that the correction wheel drives the sheet-like medium to deviate from the reference plane. The first drive mechanism is controlled to drive the support frame to rotate to the first position, and the second drive mechanism is controlled to drive the correction wheel to rotate in the first direction, so that the sheet-like medium is aligned with the reference plane.

[0020] If the first component force of the correction wheel driving the sheet-like medium to move closer to the reference plane is too small, the sheet-like medium cannot move to align with the reference plane, resulting in correction failure. Then, firstly, control the second drive mechanism to drive the correction wheel to rotate in the second direction to drive the sheet-like medium to deviate from the reference plane. Next, control the first drive mechanism to drive the support frame to rotate to the second position, so that the angle between the axis of the correction wheel and the reference plane is β, and β is less than α. Then, control the second drive mechanism to drive the correction wheel to rotate in the first direction, so that the correction wheel provides a larger first component force to drive the sheet-like medium to move closer to the reference plane, so that the sheet-like medium is aligned with the reference plane.

[0021] If the first component of the force driving the correction wheel to move the sheet-like medium closer to the reference surface is too large, causing the sheet-like medium to become stuck or squeezed at the reference surface, resulting in correction failure, then first control the second drive mechanism to drive the correction wheel to rotate in the second direction to drive the sheet-like medium to deviate from the reference surface; then control the first drive mechanism to drive the support frame to rotate to the second position, so that the angle between the axis of the correction wheel and the reference surface is β, and β is greater than α, and then control the second drive mechanism to drive the correction wheel to rotate in the first direction, so that the correction wheel provides a smaller first direction to drive the sheet-like medium to move closer to the reference surface, so that the sheet-like medium is aligned with the reference surface.

[0022] The beneficial effects of the correction device in this embodiment of the invention include: when the support frame of the correction device provided in this embodiment of the invention is in the first position, the angle between the axis of the correction wheel and the reference plane is the first angle. At this time, the second drive mechanism drives the correction wheel to rotate, which can drive the sheet-like medium to move downstream of the conveying channel and closer to the reference plane. If the correction fails, the support frame can be driven to rotate to the second position by the first drive mechanism, so that the angle between the axis of the correction wheel and the reference plane is changed from the first angle to the second angle, thereby changing the magnitude of the first component force of the correction wheel driving the sheet-like medium closer to the reference plane. If the first component force is insufficient, the second angle is made smaller than the first angle so that the correction wheel can provide a larger first component force. If the first component force is too large, the second angle is made larger than the first angle so that the correction wheel can provide a smaller first component force. In this way, the sheet-like medium can obtain a suitable first component force to push the sheet-like medium closer to the reference plane, thereby improving the success rate of the correction of the sheet-like medium.

[0023] The beneficial effects of the sheet-like media processing device in this embodiment of the invention include: the sheet-like media processing device provided in this embodiment of the invention includes the above-mentioned correction device, which can improve the success rate of sheet-like media correction.

[0024] The beneficial effects of the control method for the correction device in this embodiment of the invention include: the control method for the correction device provided in this embodiment of the invention can control the first driving mechanism to drive the support frame to rotate to a first position, so that the angle between the axis of the correction wheel and the reference plane is a first angle, control the second driving mechanism to drive the correction wheel to rotate in a first direction, so that the sheet-like medium is close to the reference plane, and determine whether the correction is successful; if the correction of the sheet-like medium is unsuccessful, control the first driving mechanism to drive the support frame to rotate to a second position, so that the angle between the axis of the correction wheel and the reference plane is a second angle, control the second driving mechanism to drive the correction wheel to rotate in a second direction opposite to the first direction, so that the sheet-like medium deviates from the reference plane, and changes the tilt state of the sheet-like medium toward the reference plane; control the first driving mechanism to drive the support frame to rotate to a first position, so that the angle between the axis of the correction wheel and the reference plane is a first angle, control the second driving mechanism to drive the correction wheel in a first direction The first drive mechanism rotates the plate to align it with a reference plane. If the first force is too large, the second angle is made smaller than the first angle. When the second drive mechanism drives the correction wheel to rotate in the second direction, a larger first force is used to drive the plate away from the reference plane, reducing the tilt angle of the plate towards the reference plane. This allows the second drive mechanism to drive the correction wheel to rotate in the first direction when the first drive mechanism drives the support frame to the first position, effectively aligning the plate with the reference plane. If the first force is insufficient, the second angle is made larger than the first angle. When the second drive mechanism drives the correction wheel to rotate in the second direction, a smaller first force is used to drive the plate away from the reference plane, increasing the tilt angle of the plate towards the reference plane. This allows the second drive mechanism to drive the correction wheel to rotate in the first direction when the first drive mechanism drives the support frame to the first position, effectively aligning the plate with the reference plane. This configuration improves the success rate of plate-type plate alignment. Attached Figure Description

[0040] This embodiment provides a sheet media processing device 010 for conveying and processing sheet media. The sheet media processing device 010 can be a printer, scanner, magnetic stripe reader / writer, check scanner, etc. The following will describe the check scanner in detail.

[0041] Figure 1 This is a schematic diagram of the structure of the sheet-like media processing device 010 in an embodiment of the present invention; please refer to... Figure 1The sheet media processing equipment 010 includes a processing mechanism 100 and a correction device 200. The correction device 200 is provided with a conveying channel 211 for conveying sheet media. The correction device 200 and the processing mechanism 100 are arranged in sequence along the conveying direction of the sheet media. This arrangement enables the sheet media to be conveyed from the correction device 200 to the processing mechanism 100. In the process of processing sheet media, the correction device 200 is used to correct the sheet media first, and then the processing mechanism 100 is used to process the corrected sheet media, thereby improving the reliability of sheet media processing.

[0042] The processing mechanism 100 can be selected as needed. In this embodiment, the processing mechanism 100 includes a magnetic element 110 for reading and writing information on a magnetic strip on a thin sheet medium such as a check. Specifically, it includes reading magnetic information on the thin sheet medium and writing magnetic information to the thin sheet medium. The magnetic element 110 includes a magnetic head 111 and a magnetic sensor, etc. Its specific structure and working principle are similar to those of related technologies, and will not be described in detail here.

[0043] Furthermore, along the conveying direction of the sheet-like medium, the correction device 200 and the magnetic element 110 are arranged at intervals; so that the sheet-like medium is corrected by the correction device 200, and then the magnetic element 110 is used to read and write information on the magnetic strip.

[0044] Optionally, the processing mechanism 100 also includes a scanning component 120, with the magnetic element 110 and the scanning component 120 arranged sequentially along the transport direction of the sheet-like medium; this arrangement allows the scanning component 120 to scan the check after the magnetic element 110 reads and writes information on the magnetic strip on the check.

[0045] Optionally, the sheet media processing device 010 also includes a ticket box 130, which is connected to the conveying channel 211 and located downstream of the scanning component 120, for collecting processed sheet media such as checks.

[0046] Optionally, a plurality of conveying rollers 131 are provided in the conveying channel 211 for driving the sheet-like medium to move within the conveying channel 211.

[0047] Of course, in other embodiments, the processing mechanism 100 may not include the scanning component 120, or the processing mechanism 100 may also include a printing component, a stamping component, etc., without specific limitations here.

[0048] Figure 2 This is a partial structural diagram of the correction device 200 in an embodiment of the present invention. Figure 1 ; Figure 3 This is a partial structural diagram of the correction device 200 in an embodiment of the present invention. Figure 2 .

[0049] Please refer toFigures 1 to 3 The correction device 200 of this embodiment includes a frame 210, a correction assembly 230, a first drive mechanism 240, and a second drive mechanism 250 disposed on the frame 210. The frame 210 is provided with a conveying channel 211 for conveying sheet-like media, and a reference surface 212 is provided on one side of the conveying channel 211. The correction assembly 230 includes a support frame 231 and a correction wheel 232. The support frame 231 is rotatably connected to the frame 210 and has a first position and a second position. The correction wheel 232 is rotatably disposed on the support frame 231 and extends into the conveying channel 211. Inside, a first drive mechanism 240 is driven to align a sheet-like medium along a reference plane 212; the first drive mechanism 240 is connected to the support frame 231 and is used to drive the support frame 231 to rotate between a first position and a second position; the second drive mechanism 250 is connected to the correction wheel 232 and is used to drive the correction wheel 232 to rotate; when the support frame 231 is in the first position, the axis of the correction wheel 232 is set at a first angle α with the reference plane 212; when the support frame 231 is in the second position, the axis of the correction wheel 232 is set at a second angle β with the reference plane 212, where β is not equal to α, and both β and α are less than or equal to 90°.

[0050] When the support frame 231 is in the first position, the angle between the axis of the correction wheel 232 and the reference plane 212 is α. Since α is less than or equal to 90°, the second drive mechanism 250 drives the correction wheel 232 to rotate. The correction wheel 232 can drive the sheet-like medium in the conveying channel 211 to move downstream and move the sheet-like medium towards the reference plane 212, so that the sheet-like medium is aligned with the reference plane 212, that is, the side of the sheet-like medium opposite to the reference plane 212 is completely in contact with the reference plane 212. If the correction fails, the support frame 231 can be driven to rotate by the first drive mechanism 240. Move to the second position to change the angle between the axis of the correction wheel 232 and the reference plane 212 from α to β, thereby changing the magnitude of the first component force of the correction wheel 232 driving the sheet-like medium closer to the reference plane 212. If the first component force is insufficient, make β less than α to utilize the correction wheel 232 to provide a larger first component force. If the first component force is too large, make β greater than α to utilize the correction wheel 232 to provide a smaller first component force. In this way, the sheet-like medium can obtain a suitable first component force to push the sheet-like medium closer to the reference plane 212 and align it along the reference plane 212, thereby improving the success rate of correction of the sheet-like medium.

[0051] It should be noted that if the sheet-like medium being corrected by the correction device 200 is thin and soft, when the support frame 231 is in the first position, the angle between the axis of the correction wheel 232 and the reference surface 212 is α. The first component force provided by the correction wheel 232 to the sheet-like medium to move closer to the reference surface 212 is small, making it impossible for the sheet-like medium to move to align with the reference surface 212, resulting in correction failure. Therefore, when correcting a thin and soft sheet-like medium, the support frame 231 can be rotated to the second position, so that the angle between the axis of the correction wheel 232 and the reference surface 212 is β, and β is less than α, so that the correction wheel 232 can provide a larger first component force, allowing the thin and soft sheet-like medium to move closer to the reference surface 212 under a larger first component force and align with the reference surface 212, thus successfully completing the correction operation. If the sheet-like medium being corrected by the correction device 200 is thick and hard, or if the angle between the sheet-like medium and the reference surface 212 is too large when the support frame 231 is in the first position, the angle between the axis of the correction wheel 232 and the reference surface 212 is α. The first component force provided by the correction wheel 232 to the sheet-like medium to move closer to the reference surface 212 is large, causing the sheet-like medium to be squeezed on the reference surface 212, and may cause jamming or wrinkling, resulting in correction failure. Then the support frame 231 is rotated to the second position, so that the angle between the axis of the correction wheel 232 and the reference surface 212 is β, and β is greater than α, so that the correction wheel 232 provides a smaller first component force, so that the thicker and harder sheet-like medium can move closer to the reference surface 212 under a smaller first component force and align with the reference surface 212 to successfully complete the correction.

[0052] Furthermore, the first included angle is greater than or equal to 30° and less than 45°, and the second included angle is greater than or equal to 0° and less than 10°, i.e., 30°≤α<45°, 0°≤β<10°. With this configuration, when the support frame 231 is in the first position, the second drive mechanism 250 drives the correction wheel 232 to rotate forward. The first component of the force by which the correction wheel 232 drives the sheet-like medium to move towards the reference surface 212 is greater than the second component of the force by which the correction wheel 232 drives the sheet-like medium to move downstream of the conveying channel 211. This facilitates ensuring that the sheet-like medium quickly aligns to the reference surface 212, thereby improving the efficiency of sheet-like medium correction. Preferably, the frame 210 is also provided with a correction surface 285, and the correction surface 285 and the reference surface 212 are respectively located on the conveying channel 211. On both sides of channel 211, the correction surface 285 and the reference surface 212 are parallel and spaced apart, with a distance between them not less than the maximum width of the sheet-like medium. The sheet-like medium is located between the correction surface 285 and the reference surface 212, and includes a first side adjacent to the reference surface 212 and a second side adjacent to the correction surface 285. In abnormal situations, for example, if the angle between the sheet-like medium and the reference surface 212 is too large when the sheet-like medium enters the conveying channel, causing the end of the first side of the sheet-like medium to abut against the reference surface 212, the sheet-like medium may become stuck. When the medium cannot continue to move, resulting in correction failure, the first drive mechanism 240 can drive the support frame 231 to rotate to the second position, and the second drive mechanism 250 can drive the correction wheel 232 to reverse. The reversed correction wheel 232 then drives the sheet-like medium to move away from the reference surface 212 and towards the correction surface 285. When the second side of the sheet-like medium contacts the correction surface 285, the sheet-like medium can rotate in a direction aligned with the correction surface 285, thereby reducing the angle between the sheet-like medium and the reference surface 212. In other words, during the backward movement, the correction surface 285 is used to perform initial correction on the skewed sheet-like medium. Then, the first drive mechanism 240 drives the support frame 231 to rotate to the first position, and the second drive mechanism 250 drives the correction wheel 232 to rotate forward again to continue the second correction. At this time, since the angle between the sheet-like medium and the reference surface 212 becomes smaller, the end of the first side of the sheet-like medium can move along the reference surface 212 and approach the reference surface 212 under the drive of the correction wheel 232, thereby ensuring the reliability of the correction.

[0053] In this embodiment, the length direction of the conveying channel 211 extends along the conveying direction of the sheet-like medium, and the reference plane 212 is located on one side of the width direction of the conveying channel 211; please refer to Figure 2The correction assembly 230 also includes a rotating member 260. Along the height direction of the conveying channel 211, the rotating member 260 and the correction wheel 232 are relatively engaged within the conveying channel 211, and are configured to jointly clamp and drive the sheet-like medium to move within the conveying channel 211. The support frame 231 is rotatably connected to the frame 210 via a pivot shaft 233, the axis of which extends along the height direction of the conveying channel 211. This arrangement ensures that during the switching between the first and second positions, the support frame 231 can maintain the relative positions of the correction wheel 232 and the rotating member 260 along the height direction of the conveying channel 211, thereby ensuring that the correction wheel 232 and the rotating member 260 reliably clamp and drive the sheet-like medium to move.

[0054] Optionally, the axis of the pivot shaft 233 intersects perpendicularly with the axis of the straightening wheel 232. This arrangement ensures that during the switching between the first and second positions, the support frame 231 can maintain the straightening wheel 232 in a position opposite to the rotating member 260, and ensures that the straightening wheel 232 and the rotating member 260 cooperate smoothly and reliably so that they can jointly and smoothly drive the sheet-like medium to move.

[0055] It should be understood that in other embodiments, the support frame 231 and the frame 210 can also be rotatably connected by a plug-in part (not shown) and an arc groove (not shown); optionally, the plug-in part is provided on the support frame 231, the arc groove is provided on the frame 210, and the first drive mechanism 240 is connected to the plug-in part in a transmission manner.

[0056] In this embodiment, the rotating component 260 is a ball bearing, and the axis of the pivot shaft 233 passes through the center of the ball bearing. This arrangement helps ensure that the correcting wheel 232 always reliably engages with the ball bearing during the rotation of the support frame 231, ensuring that the force exerted by the correcting wheel 232 on the rotating component 260 remains stable and consistent. Moreover, during the correction of sheet-like media, the rolling contact between the sheet-like media and the ball bearing reduces the frictional resistance experienced by the sheet-like media during transportation. Consequently, when the second drive mechanism 250 drives the correcting wheel 232 to rotate and drive the sheet-like media, it helps reduce the load on the second drive mechanism 250, thereby ensuring the reliability of the correction device 200. In other embodiments, the rotating component can also be a roller, with the correcting wheel 232 tangentially engaged with the roller, and the axis of the pivot shaft 233 passing through the axis of the roller and through the tangential position between the roller and the correcting wheel 232. This ensures that the correcting wheel 232 always tangentially engages with the roller during the rotation of the support frame 231.

[0057] Figure 4 This is a schematic diagram of the structure of the correction component 230, the first drive mechanism 240, and the second drive mechanism 250 in an embodiment of the present invention; in this embodiment, please refer to... Figure 2 andFigure 4 The first drive mechanism 240 includes a first motor 241 and a drive gear 242. The first motor 241 is mounted on the frame 210, and the drive gear 242 is sleeved on the pivot shaft 233 and is drive-connected to the output shaft of the first motor 241. The support frame 231 is fixedly connected to the drive gear 242. The second drive mechanism 250 includes a second motor 251 mounted on the support frame 231, and the output shaft of the second motor 251 is drive-connected to the correction wheel 232 to drive the correction wheel 232 to rotate. This configuration makes the structure of the first drive mechanism 240 simple and compact. The drive gear 242 rotates under the drive of the first motor 241, driving the support frame 231 to rotate around the pivot shaft 233. Compared to the method where the pivot shaft 233 is directly drive-connected to the first motor 241 and the support frame 231 is directly fixedly connected to the pivot shaft 233, the load on the first motor 241 can be reduced.

[0058] Alternatively, please refer to Figure 2 A bearing 261 is provided between the drive gear 242 and the pivot shaft 233. The inner ring of the bearing 261 is fixedly sleeved on the pivot shaft 233, and the outer ring of the bearing 261 is fixedly inserted into the inner hole of the drive gear 242. With this arrangement, the bearing 261 can be used to ensure the smooth rotation of the drive gear 242, further reducing the load on the first motor 241.

[0059] Alternatively, please refer to Figure 2 and Figure 4 The first drive mechanism 240 also includes a gear assembly 263, and the output shaft of the first motor 241 and the drive gear 242 are connected by the gear assembly 263.

[0060] Figure 5 for Figure 1 Enlarged view at point V; in this embodiment, please refer to... Figure 5The frame 210 includes a first channel plate 213, a second channel plate 214, and a cover plate 215. The first channel plate 213 and the second channel plate 214 are spaced apart along the height direction of the conveying channel 211, and the conveying channel 211 is formed between the first channel plate 213 and the second channel plate 214. The cover plate 215 is located on the side of the first channel plate 213 away from the second channel plate 214 and is detachably connected to the first channel plate 213. The first drive mechanism 240 is installed on the cover plate 215, and the second drive mechanism 250 is provided on the support frame 231. The support frame 231 is connected to the cover plate 215 through a pivot shaft 233. This configuration allows the correction component 230, the first drive mechanism 240, and the second drive mechanism 250 to be integrated and installed on the cover plate 215, which facilitates the modular installation of the correction device 200. Moreover, compared to installing the correction component 230, the first drive mechanism 240, and the second drive mechanism 250 on the first channel plate 213 or the second channel plate 214, it is beneficial to increase the maintenance space of the correction component 230, the first drive mechanism 240, and the second drive mechanism 250.

[0061] Optionally, the cover plate 215 is arranged parallel to and spaced apart from the first channel plate 213. One of the support frame 231 and the cover plate 215 is rotatably inserted into the first end of the pivot shaft 233; the other of the support frame 231 and the cover plate 215 is fixedly connected to the second end of the pivot shaft 233. With this arrangement, the support frame 231 can be effectively driven to rotate relative to the cover plate 215 about the axis of the pivot shaft 233, thereby enabling the support frame 231 to stably switch between the first position and the second position.

[0062] Figure 6 This is an exploded view of the structure of the correction component 230, the first drive mechanism 240, and the second drive mechanism 250 in an embodiment of the present invention; please refer to... Figure 6Specifically, in this embodiment, the support frame 231 includes a first plate 234 and a second plate 235 fixedly connected at an angle. The second drive mechanism 250 is mounted on the first plate 234. Specifically, the second motor 251 is fixedly connected to the first plate 234. The first end of the pivot shaft 233 is inserted into the second plate 235, and the second plate 235 can rotate around the pivot shaft 233. The first drive mechanism 240 is drivenly connected to the second plate 235, and the second end of the pivot shaft 233 is fixedly connected to the cover plate 215. Further, the drive mechanism 240 is drivenly connected to the second plate 235. The drive gear 242 and the second plate 235 can be fixedly connected through a pin connection structure between the drive gear 242 and the second plate 235. When the output shaft of the first motor 241 rotates, it drives the drive gear 242 to rotate, thereby driving the second plate 235 to rotate around the pivot shaft 233. This configuration simplifies the installation of the correction assembly 230, the first drive mechanism 240, the second drive mechanism 250, and the cover plate 215. Furthermore, the first drive mechanism drives the support frame 231 to rotate independently relative to the cover plate 215 via the drive gear 242. Compared to the first drive mechanism 240 directly driving the pivot shaft 233, this configuration helps reduce the load on the first drive mechanism 240.

[0063] It should be noted that the second end of the pivot shaft 233 is fixedly connected to the cover plate 215 by fasteners such as bolts; this setting makes it easier to reduce assembly difficulty.

[0064] It should be understood that in other embodiments, the first end of the pivot shaft 233 is fixedly connected to the second plate 235, the second end of the pivot shaft 233 is rotatably inserted into the cover plate 215, and the first drive mechanism 240 drives the pivot shaft 233 and the support frame 231 to rotate together relative to the cover plate 215.

[0065] Alternatively, please continue to refer to Figure 6 The correction device 200 also includes a plug-in assembly, which includes a plug-in post 243 and a slot 244 that are plugged in. The plug post 243 is disposed on one of the second plate 235 and the drive gear 242, and the slot 244 is disposed on the other of the second plate 235 and the drive gear 242. This arrangement fixes the circumferential relative position between the second plate 235 and the drive gear 242. It is only necessary to restrict the axial position between the drive gear 242 and the second plate 235 to ensure that the second plate 235 rotates synchronously when the drive gear 242 rotates. This also makes the structure of the first drive mechanism 240 and the second drive mechanism 250 simple and reliable, and helps to save space.

[0066] In this embodiment, the insertion post 243 is disposed on the end face of the drive gear 242, and the slot 244 is opened on the second plate 235; of course, in other embodiments, the insertion post 243 is disposed on the second plate 235, and the slot 244 is opened on the end face of the drive gear 242.

[0067] Alternatively, please continue to refer to Figure 6 The bearing 261 between the drive gear 242 and the pivot shaft 233 is a flange bearing. The flange 262 of the flange bearing abuts against the second plate 235. The second plate 235 is also provided with a round hole 264. The outer ring of the flange bearing is inserted into the round hole 264 and the inner hole of the drive gear 242 in sequence. This arrangement can improve the stability of the engagement between the drive gear 242 and the second plate 235.

[0068] In this embodiment, please refer to Figure 5 The first channel plate 213 and the cover plate 215 are fastened together to form a receiving cavity 216. The correction assembly 230, the first drive mechanism 240, and the second drive mechanism 250 are all installed in the receiving cavity 216. A slot 217 is provided on the first channel plate 213, through which the correction wheel 232 extends into the conveying channel 211. Placing the first drive mechanism 240 and the second drive mechanism 250 in the receiving cavity 216 can prevent the first drive mechanism 240 and the second drive mechanism 250 from being touched by foreign objects, thereby improving the reliability of the first drive mechanism 240 and the second drive mechanism 250.

[0069] Further, please refer to Figure 7 The slot 217 includes a first slot 218 and a second slot 219 that are interconnected. The first slot 218 and the second slot 219 are symmetrically distributed about the pivot axis 233, and both the first slot 218 and the second slot 219 are fan-shaped slots. The end of the first slot 218 near the center is connected to the end of the second slot 219 near the center. This arrangement can reduce the area of ​​the slot 217 while ensuring the rotation angle of the correction wheel 232 with the support frame 231, thus maintaining the strength of the first channel plate 213 and facilitating the smooth movement of the thin sheet-like medium for correction.

[0070] In this embodiment, please refer to Figure 5 The second channel plate 214 is provided with a receiving groove 220. Along the height direction of the conveying channel 211, the rotating member 260 is slidably disposed within the receiving groove 220. The receiving groove 220 has an opening 221 on the side near the first channel plate 213. The correction device 200 also includes an elastic member 222, which is connected between the rotating member 260 and the bottom wall of the receiving groove 220. This elastic member 222 ensures that the rotating member 260 always has a tendency to pass through the opening 221 and abut against the correction wheel 232. This arrangement helps ensure that the correction wheel 232 and the rotating member 260 reliably clamp the sheet-like medium, improving the stability of the sheet-like medium during movement and increasing the correction efficiency of the sheet-like medium.

[0071] It should be noted that the elastic element 222 can be selected as needed, such as a spring, elastic rubber block, etc., and no specific limitation is made here.

[0072] Figure 8 This is a partial structural diagram of the correction device 200 in an embodiment of the present invention. Figure 4 Alternatively, please refer to Figure 8 The correction device 200 also includes a first detection mechanism 270, and the sheet-like media processing device 010 also includes a controller (not shown in the figure). The controller is communicatively connected to the first detection mechanism 270 and is used to determine whether the correction is successful based on the signal output by the first detection mechanism 270.

[0073] Furthermore, the first detection mechanism 270 includes a first sensor 271 and a second sensor 272 sequentially arranged on the second channel plate 214 along the conveying direction of the sheet-like medium; when the first sensor 271 and the second sensor 272 simultaneously detect the sheet-like medium, the controller determines that the sheet-like medium correction is successful based on the signals output by both the first sensor 271 and the second sensor 272; when at least one of the first sensor 271 and the second sensor 272 fails to detect the sheet-like medium, the controller determines that the sheet-like medium correction fails based on the signals output by both the first sensor 271 and the second sensor 272.

[0074] It should be noted that the explanation is based on the following example: when the sensor detects a sheet-like medium, it outputs a high level, represented as 1; when it does not detect a sheet-like medium, it outputs a low level, represented as 0. When both the first sensor 271 and the second sensor 272 simultaneously detect a sheet-like medium, the controller determines that the sheet-like medium correction is successful based on the combined signal 1,1 output by the first sensor 271 and the second sensor 272. When the first sensor 271 detects a sheet-like medium but the second sensor 272 does not, the controller determines that the sheet-like medium correction has failed based on the combined signal 1,0 output by the first sensor 271 and the second sensor 272. Alternatively, when the first sensor 271 does not detect a sheet-like medium but the second sensor 272 does, the controller determines that the sheet-like medium correction has failed based on the combined signal 0,1 output by the first sensor 271 and the second sensor 272. Or, when neither the first sensor 271 nor the second sensor 272 detects a sheet-like medium, the controller determines that the sheet-like medium correction has failed based on the combined signal 0,0 output by the first sensor 271 and the second sensor 272.

[0075] Alternatively, please refer to Figure 8The correction device 200 also includes a second detection mechanism 280. When the support frame 231 is in the first position, the second detection mechanism 280 outputs a first signal; when the support frame 231 is in the second position, the second detection mechanism 280 outputs a second signal. The second detection mechanism 280 is communicatively connected to the controller. When the controller receives the first signal, it determines that the support frame 231 is in the first position; when the controller receives the second signal, it determines that the support frame 231 is in the second position. With this configuration, the position of the support frame 231 can be determined based on the different signals received by the controller.

[0076] Furthermore, the second detection mechanism 280 includes a third sensor 281, a fourth sensor 282, a first detection element, and a second detection element. The third sensor 281 and the fourth sensor 282 are both mounted on the second channel plate 214, while the first and second detection elements are mounted on the correction assembly 230. When the support frame 231 is in the first position, the first detection element cooperates with the third sensor 281, and the second detection element separates from the fourth sensor 282. The third sensor 281 and the fourth sensor 282 output a first combined signal. When the support frame 231 is in the second position, the first detection element separates from the third sensor 281, and the second detection element cooperates with the fourth sensor 282. The third sensor 281 and the fourth sensor 282 output a second combined signal.

[0077] It should be noted that when the sensor is engaged with the detection element, the sensor outputs a high level, represented by 1; when the sensor is separated from the detection element, the sensor outputs a low level, represented by 0. When the support frame 231 is in the first position, the first combined signal output by the third sensor 281 and the fourth sensor 282 is 1,0; when the support frame 231 is in the second position, the second combined signal output by the third sensor 281 and the fourth sensor 282 is 0,1. Of course, in other embodiments, when the sensor is engaged with the detection element, the sensor outputs a low level, represented by 0; when the sensor is separated from the detection element, the sensor outputs a high level, represented by 1.

[0078] Alternatively, please continue to refer to Figure 8 The correction device 200 also includes a paper feed sensor 283, which is disposed in the conveying channel 211 and is communicatively connected to the controller. When the paper feed sensor 283 detects a sheet-like medium, the controller determines that the sheet-like medium has entered the conveying channel 211 based on the signal output by the paper feed sensor 283. When the paper feed sensor 283 does not detect a sheet-like medium, the controller determines that no sheet-like medium has entered the conveying channel 211 based on the signal output by the paper feed sensor 283.

[0079] It should be noted that the condition for determining the failure of thin sheet media correction can be that after the paper feed sensor 283 detects the thin sheet media, neither the first sensor 271 nor the second sensor 272 detects the thin sheet media within a set time, or that after the first sensor 271 detects the thin sheet media, the second sensor 272 fails to detect the thin sheet media within a set time, etc., without specific limitations here.

[0080] It should be noted that the aforementioned communication connection can refer to various cable connection methods, WiFi wireless connection methods, etc. provided by relevant technologies, and is not specifically limited here.

[0081] The correction device 200 in this embodiment also includes a protective cover 284, which covers the outside of the second drive mechanism 250 and the first drive mechanism 240 to prevent the first drive mechanism 240 and the second drive mechanism 250 from interfering with the magnetic signal of the magnetic element 110.

[0082] When the sheet-like media processing device 010 of this embodiment is used to process sheet-like media, it can first use the correction device 200 to correct the deviation of the sheet-like media, and then use the processing mechanism 100 to perform magnetic stripe reading and writing and other processing on the sheet-like media.

[0083] In summary, when the sheet-like media processing equipment 010 provided by the present invention uses the correction device 200 to correct the sheet-like media, the first drive mechanism 240 controls the support member to rotate to the first position, and the angle between the axis of the correction wheel 232 and the reference plane 212 is α. At this time, the second drive mechanism 250 drives the correction wheel 232 to rotate, which can drive the sheet-like media to move downstream of the conveying channel 211 and closer to the reference plane 212. If the correction fails, the first drive mechanism 240 can drive the support frame 231 to rotate to the second position. The angle between the axis of the correction wheel 232 and the reference plane 212 is changed from α to β, thereby changing the magnitude of the first component force of the correction wheel 232 driving the sheet-like medium closer to the reference plane 212. If the first component force is insufficient, β is made smaller than α so that the correction wheel 232 can provide a larger first component force. If the first component force is too large, β is made larger than α so that the correction wheel 232 can provide a smaller first component force. In this way, the sheet-like medium can obtain a suitable first component force to push the sheet-like medium closer to the reference plane 212, thereby improving the success rate of correction of the sheet-like medium.

[0084] The present invention also provides a control method for a correction device 200. The control method includes controlling a first driving mechanism 240 to drive a support frame 231 to rotate to a first position, controlling a second driving mechanism 250 to drive a correction wheel 232 to rotate along a first direction, so that the correction wheel 232 drives the sheet-like medium closer to a reference surface 212, and determining whether the correction of the sheet-like medium is successful; when it is determined that the correction of the sheet-like medium is unsuccessful, controlling the first driving mechanism 240 to drive the support frame 231 to rotate to a second position or a first position, controlling the second driving mechanism 250 to drive the correction wheel 232 to rotate along a second direction opposite to the first direction, so that the correction wheel 232 drives the sheet-like medium to deviate from the reference surface 212; controlling the first driving mechanism 240 to drive the support frame 231 to rotate to a first position or a second position, controlling the second driving mechanism 250 to drive the correction wheel 232 to rotate along the first direction, so that the sheet-like medium is aligned with the reference surface 212.

[0085] Specifically, when the sheet-like medium enters the conveying channel 211, the first drive mechanism 240 drives the support frame 231 to rotate to the first position, making the angle between the axis of the correction wheel 232 and the reference surface 212 α. When the second drive mechanism 250 drives the correction wheel 232 to rotate in the first direction, if the angle between the first side of the sheet-like medium and the reference surface 212 is too large, the first component force of the correction wheel 232 driving the sheet-like medium to move closer to the reference surface 212 will cause the sheet-like medium, which is already tilted towards the reference surface 212, to become stuck or squeezed onto the reference surface 212, resulting in correction failure. Then, the first drive mechanism 240 will rotate the support frame 231 to the first position, making the angle between the axis of the correction wheel 232 and the reference surface 212 α, resulting in correction failure. The first drive mechanism 240 drives the support frame 231 to rotate to the second position, making the angle between the axis of the correction wheel 232 and the reference plane 212 β, and making β less than α. The second drive mechanism 250 drives the correction wheel 232 to rotate in the second direction, using a larger first component force to drive the sheet-like medium to deviate from the reference plane 212. Then, the first drive mechanism 240 drives the support frame 231 to rotate to the first position, making the angle between the axis of the correction wheel 232 and the reference plane 212 α, and when the second drive mechanism 250 drives the correction wheel 232 to rotate in the first direction, the correction wheel 232 drives the sheet-like medium closer to the reference plane. The sheet-like medium moves in direction 212, aligning it with the reference surface 212. Further, if the sheet-like medium being corrected is too thick or hard, or if the angle between the first side of the sheet-like medium and the reference surface 212 is too large when the sheet-like medium enters the conveying channel, causing correction failure, then the first drive mechanism 240 drives the support frame 231 to rotate to the second position, making the angle between the axis of the correction wheel 232 and the reference surface 212 β, and ensuring that β is less than α. The second drive mechanism 250 drives the correction wheel 232 to rotate in the second direction, using a larger first component force to drive the sheet-like medium away from the reference surface 212, and when the sheet... When the second side of the sheet-like medium contacts the correction surface 285, the correction effect of the correction surface 285 on the sheet-like medium can reduce the angle between the first side of the sheet-like medium and the reference surface 212, thereby improving the success rate of the sheet-like medium when it is corrected again. It also helps to ensure that the sheet-like medium can always keep in contact with the correction wheel 232 when the correction wheel 232 rotates in the second direction. This prevents the sheet-like medium from completely exiting the correction wheel 232 or even exiting the conveying channel 211 during the paper ejection process, thus preventing it from being automatically corrected a second time. This allows for multiple automatic corrections without human intervention.

[0086] It should be noted that the control method of the correction device 200 can also be as follows: When correcting a thin and soft sheet-like medium, the first drive mechanism 240 drives the support frame 231 to rotate to a first position, so that the angle between the axis of the correction wheel 232 and the reference plane 212 is α, and the second drive mechanism 250 drives the correction wheel 232 to rotate in the first direction. If the first component force of the correction wheel 232 driving the sheet-like medium to move closer to the reference plane 212 is too small, the sheet-like medium cannot move to align with the reference plane 212, and the correction fails. Then, the second drive mechanism 250 drives the correction wheel 232 to rotate in the second direction, causing the sheet-like medium to deviate from the reference plane 212; then, the first drive mechanism 240 drives the support frame 231 to rotate to the second position, so that the angle between the axis of the correction wheel 232 and the reference plane 212 is β, and β is less than α. The second drive mechanism 250 is controlled to drive the correction wheel 232 to rotate in the first direction, so that the correction wheel 232 provides a larger first component force to drive the sheet-like medium to move closer to the reference plane 212, so that the sheet-like medium is aligned with the reference plane 212. When correcting a thicker, harder sheet-like medium, the first drive mechanism 240 drives the support frame 231 to rotate to a first position, making the angle between the axis of the correction wheel 232 and the reference surface 212 α. When the second drive mechanism 250 drives the correction wheel 232 to rotate in the first direction, the first component force of the correction wheel 232 driving the sheet-like medium to move closer to the reference surface 212 is too large. The sheet-like medium becomes stuck or compressed at the reference surface 212, and the correction fails. Then, the second drive mechanism... The second drive mechanism 250 drives the correction wheel 232 to rotate in the second direction, causing the sheet-like medium to deviate from the reference plane 212. Then, the first drive mechanism 240 drives the support frame 231 to rotate to the second position, so that the angle between the axis of the correction wheel 232 and the reference plane 212 is β, and β is greater than α. The second drive mechanism 250 is controlled to drive the correction wheel 232 to rotate in the first direction, so that the correction wheel 232 provides a smaller first direction drive to move the sheet-like medium closer to the reference plane 212, so that the sheet-like medium is aligned with the reference plane 212.

[0087] In summary, the control method of the correction device 200 provided by the present invention can improve the success rate of correction of thin sheet media.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

If the first component force driving the sheet-like medium to move closer to the reference surface is too large, causing the sheet-like medium to become stuck or squeezed at the reference surface, resulting in correction failure, then firstly, the second driving mechanism is controlled to drive the correction wheel to rotate along the second direction to drive the sheet-like medium to deviate from the reference surface; then, the first driving mechanism is controlled to drive the support frame to rotate to the second position, so that the angle between the axis of the correction wheel and the reference surface is β, and β is greater than α; then, the second driving mechanism is controlled to drive the correction wheel to rotate along the first direction, so that the correction wheel provides a smaller first directional driving force to move the sheet-like medium closer to the reference surface, so that the sheet-like medium is aligned with the reference surface.
