Description

Technical Field

[0001] The present invention relates to the technical field of invoice scanning, in particular to an invoice scanning and inputting device. Background Art

[0002] Invoice scanning is usually used in many scenarios. When entering invoices in hospitals, they will be divided into multiple batches, such as public expenditures, personal reimbursements, medical expenses, etc. When scanning and entering invoices in hospitals, invoices are usually processed centrally. When scanning, problems such as the opposite direction of the invoice are often encountered. At this time, image editing software can be used to adjust the direction and angle of the image to reduce the time consumed by repeated scanning.

[0003] Considering that hospitals usually select fixed dates for centralized processing when entering invoices, the invoices may not be completely aligned when they are sorted. During the use of the equipment, paper jams may occur due to uneven paper positions or wrinkles at corners. When a paper jam occurs, the equipment needs to be manually dismantled to remove it. Considering that the existing technology will not be able to sort invoices that are folded in half or in the opposite direction of the sorting direction, they need to be put back into the equipment for entry after manual sorting, which will cause additional trouble for personnel. Summary of the invention

[0004] The purpose of the present invention is to provide an invoice scanning and inputting device to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an invoice scanning and inputting device, comprising a scanner housing, A feed port is provided on the top of the scanner housing, a discharge port is provided on one end surface of the scanner housing, and a collecting rack is fixedly connected to the discharge port on one side of the end surface of the scanner housing; A transfer plate and a baffle are fixedly connected to the inner wall of the scanner housing near the feed port, the baffle is vertically arranged, the transfer plate is inclined, and the end of the transfer plate near the baffle is lower than the end away from the baffle; a paper pickup motor is arranged inside the scanner housing, the output shaft of the paper pickup motor is fixedly connected to a paper pickup wheel, and the paper pickup wheel is rotatably connected to the end of the transfer plate near the baffle; A conveying unit is provided on one side of the scanner housing near the discharge port, and the conveying unit is used to deliver the invoice; a scanner is provided above the conveying unit and is fixedly connected to the scanner housing; the scanner is used to scan the invoice; The side of the pickup wheel away from the transfer plate is slidably connected with a stop plate and is fixedly connected to the scanner housing; the bottom of the inner wall of the scanner housing is fixedly connected with a reciprocating mechanism, a sorting mechanism and a collecting mechanism from left to right in sequence; the reciprocating mechanism is located below the transmission unit; a paper extraction mechanism is provided between the transmission unit, the stop plate and the reciprocating mechanism; the reciprocating mechanism is fixedly connected to the paper extraction mechanism; the reciprocating mechanism is used to adjust the position of the paper extraction mechanism; the paper extraction mechanisms are slidably connected to the transmission unit and the stop plate, and the initial state of the paper extraction mechanism is inclined toward the direction of the sorting mechanism; the sorting mechanism is located below the transfer plate; a monitor is provided on the top of the inner wall of the scanner housing, and the scanning direction of the monitor is toward the pickup wheel and the stop plate; The paper-drawing mechanism includes an adjusting motor, and the output end of the adjusting motor is fixedly connected to a paper-drawing shell; a paper clamping opening is provided on a side of the paper-drawing shell close to the stop plate; paper clamping boards are provided on both sides of the paper clamping opening and are slidably connected to the inner wall of the paper-drawing shell; a paper clamping unit is slidably connected to the inner wall of the paper-drawing mechanism; and the paper clamping unit is fixedly connected to a side away from the paper clamping board.

[0006] With the above technical solution, when entering invoices, first stack the invoices and put them in from the feed port. After the invoices are put in, they will fall on the top of the transfer plate. Since the transfer plate itself is inclined, the invoices will move toward the baffle plate spontaneously, and the invoices will be passed one by one through the pickup wheel and scanned. When the invoice is jammed due to misalignment, or the monitor finds that the invoice has corners and wrinkles, the paper pickup motor will stop driving the paper pickup wheel to rotate. At this time, the invoice will slide to the stop plate, and the paper extraction mechanism will be lifted by the reciprocating mechanism. The paper extraction shell will be rotated by adjusting the motor, and the paper clamping port will be parallel to the top surface of the stop plate to ensure that the invoice can be accurately clamped, and the paper clamping papers are brought close to each other through the paper clamping unit to clamp the invoice. The above method does not require manual operation to handle paper jams, and the paper jams can be rearranged through the sorting mechanism after being pulled out, which can minimize the time for manual handling of paper jams or paper wrinkles.

[0007] Furthermore, the paper clamping unit includes an electric telescopic rod, and the outer wall of the electric telescopic rod is symmetrically hinged with an adjusting rod; the inner walls of the paper drawing shell on both sides close to the electric telescopic rod are symmetrically fixedly connected with hinge blocks, and the opposite side of the hinge block is hinged with a traction rod; the middle part of the traction rod is hinged with the adjusting rod, and the end of the traction rod away from the hinge block is in contact with the paper clamping board; the paper clamping board and the paper drawing shell are connected by a reset spring.

[0008] By adopting the above technical solution, while the paper drawing shell is lifted by the reciprocating mechanism, the position of the paper clip can be controlled by setting the traction rod. When in use, the electric telescopic rod is started to retract the part that has been extended into the paper drawing shell, and at the same time, the traction rod can be pulled by the synchronous movement of the adjustment rod and the electric telescopic rod. Since the position of one end of the traction rod connected to the hinge block is fixed, and the other end of the traction rod is in contact with the paper clip, the paper clips will be pushed closer to each other when the traction rod is pulled, thereby achieving the effect of clamping the invoice.

[0009] Furthermore, the reciprocating mechanism includes a fixed block, the bottom of the fixed block is fixedly connected to the scanner housing, the top of the fixed block is fixedly connected to a fixed slider, and a sliding groove is provided at the top of the fixed block on a side away from the fixed slider; the inner wall of the sliding groove is slidably connected to a reciprocating motor; the output end of the reciprocating motor is fixedly connected to a reciprocating screw; the end of the reciprocating screw away from the reciprocating motor is rotatably connected to a connecting block; both ends of the connecting block away from the reciprocating screw are hinged with a first connecting rod; a transverse sliding groove is provided on the inner wall of the scanner housing; the end of the first connecting rod away from the connecting block is hinged to a second connecting rod, and the outer wall of the end at which the first connecting rod and the second connecting rod are hinged is slidably connected to the transverse sliding groove; a rotating rod is fixedly connected to the inner wall of the scanner housing on one side close to the second connecting rod, and the end of the rotating rod away from the scanner housing passes through the middle of the second connecting rod and is rotatably connected to the second connecting rod; the opposite side of the second connecting rod away from the end of the first connecting rod is fixedly connected to the adjusting motor.

[0010] By adopting the above technical solution, by starting the reciprocating motor, the reciprocating motor will drive the reciprocating screw to rotate, so the reciprocating screw will rotate while driving the connecting block to move, and the connecting block will pull one end of the first connecting rod to move, and slide through the hinge between the first connecting rod and the second connecting rod and the transverse slide groove, and the second connecting rod will be subjected to a larger deflection angle, at this time, the second connecting rod can be rotated through the rotating rod, and the position of the paper extraction mechanism can be controlled by the rotation of the second connecting rod, and the angle of the paper extraction mechanism can be controlled by adjusting the motor; therefore, when encountering a paper jam or the like, the paper extraction mechanism can be driven to a specified position, and after the paper extraction mechanism clamps the invoice, the transverse slide groove allows the second connecting rod to obtain a larger deflection angle to remove the invoice from the paper pickup wheel, and after the invoice is removed, the reciprocating mechanism can be reset by the movement of the reciprocating screw, and the paper extraction mechanism can also be reset; After the invoice is passed to the scanner through the conveying unit and scanned, it is collected by the collection rack to facilitate subsequent filing and sorting.

[0011] Furthermore, the sorting mechanism includes a sorting frame, the bottom of which is fixedly connected to the scanner housing, a transmission unit is arranged inside the sorting frame, a fixing frame is fixedly connected to the top of the sorting frame, a laser scanner is arranged on the side of the fixing frame facing the transmission unit, and rolling wheels are rotatably connected to both sides of the fixing frame; a flip motor is arranged inside the sorting frame, a flip plate is fixedly connected to the output end of the flip motor, and the bottom of the flip plate is in contact with the surface of the invoice.

[0012] By adopting the above technical solution, when the invoice leaves the paper extraction mechanism, it moves from the tail toward the sorting mechanism. When the invoice falls on the transmission unit, it will be transferred to the fixed frame, and when the invoice passes through the flip plate, the flip plate will fit with the surface of the invoice. When the flip plate encounters a folded corner, it will be blocked by the folded corner. At this time, the laser scanner on the fixed frame detects that the flip plate is blocked and starts the flip motor, and the flip motor drives the flip plate to flip, so that the folded corner is spread out at the same time as the flip plate flips, thereby avoiding force on the crease while spreading the folded corner, ensuring the integrity of the invoice, and flattening the invoice by the rolling wheel after processing the folded corner to ensure that the invoice will not have wrinkles.

[0013] Further, the collecting mechanism includes a collecting lower shell and a collecting box, the collecting lower shell is located below the collecting box, a lifting air pump is arranged at the center of the bottom of the inner wall of the collecting lower shell, air outlets are arranged on both sides of the lifting air pump, and the air outlets are fixedly connected with a pneumatic outer shell, the inner wall of the pneumatic outer shell is slidably connected with a pneumatic rod, the top of the pneumatic rod is fixedly connected with the bottom of the collecting box, the top of the pneumatic rod is communicated with the collecting box, and the bottom of the pneumatic rod is communicated with the pneumatic outer shell; a plurality of groups of first lifting shells and second lifting shells are fixedly connected with the bottom of the inner wall of the collecting box, the inner wall of the first lifting shell is slidably connected with a first lifting rod, and the inner wall of the second lifting shell is slidably connected with a second lifting rod, the length of the first lifting rod is shorter than that of the second lifting rod, the tops of the first lifting rod and the second lifting rod are fixedly connected with a collecting plate, and the first lifting shell is closer to the sorting mechanism than the second lifting shell; the outer wall of the collecting plate is slidably connected with the inner wall of the collecting box.

[0014] By adopting the above technical scheme, invoices are collected by a collection box and a collection plate. After the monitor detects that no invoices enter the paper pickup wheel, the lifting air pump is started to inflate the pneumatic shell, and the pneumatic rod moves upward through the airflow. At this time, the pneumatic rod will push the collection box to move upward; the airflow through the pneumatic rod pushes the collection plate to move. Since the first lifting rod is shorter than the second lifting rod, the second lifting rod is still moving upward when the first lifting rod rises to the top, and the collection plate can be tilted at this time. The inclination of the collection plate can make the invoice inside tilt, and the invoice can be aligned according to the tilt direction. When the collection box rises to the top, the invoice will move toward the baffle due to the tilt; through the above operation, the device can automatically operate to perform a second scan of the sorted invoices in the collection box when it detects that no invoices are transmitted from the paper pickup wheel, and a second sorting will be performed when it is detected that there is still a problem with the invoice.

[0015] Furthermore, an inclined block is provided on the top of the paper-drawing housing, and the inclined block is in contact with the stop plate.

[0016] By adopting the above technical solution, the setting of the inclined block can not only make the paper-drawing shell blocked by the stop plate after rotating to the specified angle, but also align the paper clamping mouth with the sorting mechanism by limiting the position and angle, thereby preventing excessive deflection. At the same time, the direction of the invoice can be guided by the inclination of the top of the inclined block.

[0017] Furthermore, a throttle block is arranged inside the pneumatic rod, and the throttle block is used to throttle the airflow.

[0018] By adopting the above technical solution, the air flow rate can be reduced by setting the throttling block to prevent the collection plate from rising too fast.

[0019] Furthermore, a spline shaft is fixedly connected to the bottom of the inner wall of the collecting lower shell, and one end of the spline shaft away from the collecting lower shell is fixedly connected to the collecting box.

[0020] By adopting the above technical solution, the collection box can be supported by the setting of the spline shaft, and the characteristics of the spline shaft can be used to limit the collection box during its rising process to prevent the collection box from being out of position.

[0021] Furthermore, a plurality of rotating holes are provided on the top of the transfer plate, rollers are rotatably connected in the rotating holes, the center of the rollers is lower than the top surface of the transfer plate, a first pressure block is fixedly connected to the top of the transfer plate, and a second pressure block is fixedly connected to the bottom of the baffle.

[0022] By adopting the above technical solution, when the invoice is on the transmission plate, the invoice will be slid toward the baffle through the roller and blocked by the baffle. While rubbing the paper, the first pressing block and the second pressing block can be used to unfold the folded corner at the tail of the invoice to avoid failure of entry due to the folded corner during entry. When the collection plate passes the invoice up, the invoice can be moved to the baffle through the roller. At the same time, considering that the stacked invoices will produce pressure on the bottom invoice, the bottom invoice will not be able to move above the roller, thereby causing the bottom invoice to be unable to move normally to the baffle. At this time, due to the characteristic that the center of the roller is lower than the top surface of the transmission plate, the part of the roller on the top surface of the transmission plate is lower, so that the invoice can be moved normally from the roller while avoiding being stuck by the roller.

[0023] The present invention has the following beneficial effects: 1. When an invoice encounters a paper jam or a corner wrinkle, the paper pickup motor will stop driving the paper pickup wheel to rotate, and the invoice will slide onto the stop plate. The reciprocating mechanism and the adjusting motor will make the paper clamping opening parallel to the top surface of the stop plate to ensure that the invoice can be accurately clamped. The electric telescopic rod drives the adjusting rod to adjust the position of the traction rod, and the traction rod pushes the paper clamps to approach each other to clamp the invoice. The method does not require manual operation to handle paper jams, and after the paper jams are pulled out, the paper jams can be re-arranged by the sorting mechanism, which can reduce the time for manual handling of paper jams or paper wrinkles.

[0024] 2. In the present invention, when the invoice is separated from the paper extraction mechanism, it moves from the tail to the sorting mechanism. When the invoice falls on the transmission unit, it will be transmitted to the fixed frame, and when the invoice passes through the flip plate, the flip plate will fit with the surface of the invoice. When the flip plate encounters a folded corner, it will be blocked by the folded corner. At this time, the laser scanner on the fixed frame detects that the flip plate is blocked and starts the flip motor, and the flip motor drives the flip plate to flip, so that the folded corner is spread out while the flip plate flips, thereby avoiding stress on the crease while spreading the folded corner, ensuring the integrity of the invoice, and flattening the invoice by the rolling wheel after processing the folded corner to ensure that the invoice will not have wrinkles.

[0025] 3. The present invention collects the sorted invoices through a collection box and a collection plate. After the monitor detects that no invoices enter the paper pickup wheel, the lifting air pump is started to inflate the inside of the pneumatic shells on both sides, and the airflow pushes the limit plate so that the pneumatic rod can move upward. At this time, the pneumatic rod will push the collection box to move upward; when the airflow enters the pneumatic shell, the pneumatic rod can inflate the inside of the collection box. At this time, the airflow will push the collection plate to move. Since the first lifting rod is shorter than the second lifting rod, the collection plate will be tilted, the invoices inside will be tilted, and the invoices will be aligned according to the tilt direction. When the collection box rises to the top, the invoices will move toward the baffle. BRIEF DESCRIPTION OF THE DRAWINGS

The discharge port is located at one side of the end surface of the scanner housing 1 and is fixedly connected to a collecting rack 12. A transfer plate 13 and a baffle 14 are fixedly connected to the inner wall of the scanner housing 1 near the feed port 11. The baffle 14 is vertically arranged, and the transfer plate 13 is inclined, and the end of the transfer plate 13 near the baffle 14 is lower than the end away from the baffle 14. A paper pickup motor is arranged inside the scanner housing 1, and a paper pickup wheel 15 is fixedly connected to the output shaft of the paper pickup motor. The paper pickup wheel 15 is rotatably connected to the end of the transfer plate 13 near the baffle 14. A conveying unit 16 is provided on one side of the scanner housing 1 near the discharge port, and the conveying unit 16 is used to deliver the invoice; a scanner 17 is provided above the conveying unit 16 and is fixedly connected to the scanner housing 1; the scanner 17 is used to scan the invoice; The side of the paper pickup wheel 15 away from the transmission plate 13 is slidably connected with a stop plate 151 and fixedly connected to the scanner housing 1; the bottom of the inner wall of the scanner housing 1 is fixedly connected with a reciprocating mechanism 2, a sorting mechanism 4 and a collecting mechanism 5 in sequence from left to right; the reciprocating mechanism 2 is located below the transmission unit 16; a paper extraction mechanism 3 is arranged between the transmission unit 16, the stop plate 151 and the reciprocating mechanism 2; the reciprocating mechanism 2 is fixedly connected with the paper extraction mechanism 3; the reciprocating mechanism 2 is used to adjust the position of the paper extraction mechanism 3; the paper extraction mechanism 3 is slidably connected with the transmission unit 16 and the stop plate 151, and the initial state of the paper extraction mechanism 3 is inclined in the direction of the sorting mechanism 4; the sorting mechanism 4 is located below the transmission plate 13; a monitor 18 is arranged on the top of the inner wall of the scanner housing 1, and the scanning direction of the monitor 18 is toward the paper pickup wheel 15 and the stop plate 151; The paper extraction mechanism 3 includes an adjusting motor 311, and the output end of the adjusting motor 311 is fixedly connected to the paper extraction shell 31; a paper clamping opening 32 is provided on one side of the paper extraction shell 31 close to the stop plate 151; paper clamping boards 33 are provided on both sides of the paper clamping opening 32 and are slidably connected to the inner wall of the paper extraction shell 31; a paper clamping unit 6 is slidably connected to the inner wall of the paper extraction mechanism 3; and the paper clamping unit 6 is fixedly connected to the side away from the paper clamping board 33.

[0031] In this embodiment, considering that invoices are usually entered on a fixed date for centralized processing in hospitals, the invoices may not be completely aligned when they are sorted, and paper jams may occur during the use of the device due to uneven paper positions or folded corners. When paper jams occur, the device needs to be manually dismantled to remove them; considering that the invoices need to be put back into the device for entry after sorting, this will cause additional trouble to the personnel; When entering invoices, first stack the invoices and put them in from the feed port 11. After the invoices are put in, they will fall on the top of the transfer plate 13. Since the transfer plate 13 itself is inclined, the invoices will move toward the baffle 14 spontaneously, and the invoices will be passed one by one through the pickup roller 15 and scanned by the monitor 18. When the invoice is normal, it will be transferred to the scanner 17 through the transmission unit 16, scanned, and then collected by the collection rack 12, so as to facilitate subsequent filing and sorting; when the invoice is jammed or has corner wrinkles, the position of the paper extraction mechanism 3 will be adjusted by the reciprocating mechanism 2, and the paper extraction mechanism 3 will adjust its own angle and clamp the invoice. After the invoice is extracted, it will be transferred to the sorting mechanism 4, and the invoice will be processed for corner wrinkles at the sorting mechanism 4, and collected by the collection mechanism 5 after sorting. When there is no invoice to be scanned, the invoice in the collection mechanism 5 will be re-scanned; When the invoice is not placed in the right position and causes a paper jam, or the monitor 18 finds that the invoice has a folded corner, the paper pickup motor will stop driving the paper pickup wheel 15 to rotate. At this time, the invoice will slide onto the stop plate 151, and the paper extraction mechanism 3 will be lifted by the reciprocating mechanism 2, and the paper extraction shell 31 will be rotated by adjusting the motor 311, and the paper clamping port 32 will be parallel to the top surface of the stop plate 151 to ensure that the invoice can be accurately clamped. At this time, the paper clamping unit 6 can push the paper clamping board 33 to move, and the paper clamping boards 33 are close to each other, so as to clamp the invoice. After holding the invoice, the reciprocating mechanism 2 will still pull the paper extraction mechanism 3 backwards, thereby pulling out the stuck invoice; when the invoice size reaches the maximum value, the reciprocating mechanism 2 will reset the paper extraction mechanism 3. During the resetting process, the invoice will be pulled open by the paper clamping unit 6 due to its own gravity and the action of the adjustment motor 311. At the same time, because the paper extraction mechanism 3 is inclined, the invoice will slide down and enter the sorting mechanism 4 for re-sorting, and then be collected by the collecting mechanism 5. After the invoice processing is completed, the invoice in the collecting mechanism 5 will be re-scanned; Through the above operation, the folded corners and paper jams of the invoice can be discovered autonomously, and the invoice can be taken out from the paper pickup wheel 15 through the paper extraction mechanism 3. The time of manual removal of the equipment for paper jams is saved, and the paper jams can be automatically handled. The folded corners and folds of the invoice can be automatically detected. In the initial state, the paper extraction mechanism 3 does not affect the movement of the invoice. When there is a problem with the invoice, the invoice will be clamped by the paper extraction mechanism 3, and reset after the invoice is completely taken out, so that the invoice can be passed to the sorting mechanism 4 for re-sorting.

[0032] Specifically, the paper clamping unit 6 includes an electric telescopic rod 34, and the outer wall of the electric telescopic rod 34 is symmetrically hinged with an adjusting rod 35; the inner walls of the paper drawing shell 31 on both sides close to the electric telescopic rod 34 are symmetrically fixedly connected with hinge blocks 37, and the opposite side of the hinge block 37 is hinged with a traction rod 36; the middle part of the traction rod 36 is hinged with the adjusting rod 35, and the end of the traction rod 36 away from the hinge block 37 is in contact with the clamping paper board 33; the clamping paper board 33 and the paper drawing shell 31 are connected by a reset spring 331.

[0033] In this embodiment, when the paper-drawing housing 31 is lifted by the reciprocating mechanism 2, the position of the paper clipping paper 33 can be controlled by setting the traction rod 36. When in use, the electric telescopic rod 34 is started to retract the part that has been extended into the paper-drawing housing 31, and at the same time, the traction rod 36 can be pulled by the synchronous movement of the adjustment rod 35 and the electric telescopic rod 34. Since the position of one end of the traction rod 36 connected to the hinge block 37 is fixed, and the other end of the traction rod 36 is in contact with the paper clipping paper 33, the traction rod 36 is pulled and the paper clipping paper 33 is pushed closer to each other, thereby achieving the effect of clamping the invoice; After the paper extraction mechanism 3 is moved to the maximum size of the invoice by the reciprocating mechanism 2, the electric telescopic rod 34 moves into the paper extraction housing 31 so that the traction rod 36 releases the clamping paper board 33 under the pull of the adjusting rod 35. At this time, the clamping paper board 33 can be pulled back by the reset spring 331, thereby releasing the clamping of the invoice, and the invoice will slide down to the inside of the sorting mechanism 4 through the inclined paper extraction housing 31; through the above method, no manual operation is required to handle paper jams, and the paper jams can be re-sorted through the sorting mechanism 4 after pulling out the paper jams, which can reduce the time for manual handling of paper jams or paper wrinkles.

[0034] Specifically, the reciprocating mechanism 2 includes a fixed block 21, the bottom of which is fixedly connected to the scanner housing 1, the top of which is fixedly connected to a fixed slider 23, and a sliding groove is provided on the top of the fixed block 21 on a side away from the fixed slider 23; a reciprocating motor 22 is slidably connected to the inner wall of the sliding groove; a reciprocating screw rod 24 is fixedly connected to the output end of the reciprocating motor 22; an end of the reciprocating screw rod 24 away from the reciprocating motor 22 is rotatably connected to a connecting block 25; both ends of the connecting block 25 away from the reciprocating screw rod 24 are hingedly connected to a first connecting rod 26; A transverse slide groove 19 is provided on the inner wall of the scanner housing 1; the end of the first connecting rod 26 away from the connecting block 25 is hinged with the second connecting rod 27, and the outer wall of the end where the first connecting rod 26 and the second connecting rod 27 are hinged is slidably connected to the transverse slide groove 19; a rotating rod is fixedly connected to the inner wall of the scanner housing 1 on one side close to the second connecting rod 27, and the end of the rotating rod away from the scanner housing 1 passes through the middle part of the second connecting rod 27 and is rotatably connected to the second connecting rod 27; the opposite side of the second connecting rod 27 away from the end of the first connecting rod 26 is fixedly connected to the adjustment motor 311.

[0035] In this embodiment, considering that the paper extraction mechanism 3 not only needs to contact the top of the conveying unit 16 when moving, but also needs to be reset, the reciprocating mechanism 2 needs to have the ability of reciprocating motion; the setting of the fixed block 21 can limit the position of the reciprocating motor 22 and the fixed slider 23. When encountering paper jams or wrinkles, the reciprocating motor 22 is started, and the reciprocating motor 22 drives the reciprocating screw 24 to rotate. At this time, the fixed slider 23 will slide in the thread of the reciprocating screw 24. Since the fixed slider 23 is fixed, the reciprocating screw 24 will rotate while driving the connecting block 25 to move. When the reciprocating screw 24 moves, the reciprocating motor 22 will also move with it. The connecting block 25 will pull one end of the first connecting rod 26 to move, and the second connecting rod 26 and the second connecting rod 27 will slide through the horizontal slide groove 19 at the hinged joint and the horizontal slide groove 19. The second connecting rod 27 can have a larger deflection angle and a larger lateral movement space to avoid being stuck with the conveying unit 16 during the rotation of the second connecting rod 27. The second connecting rod 27 can be rotated by the rotating rod, and the position of the paper extraction mechanism 3 can be controlled by the rotation of the second connecting rod 27, and the angle of the paper extraction mechanism 3 can be controlled by adjusting the motor 311; therefore, when encountering a paper jam, the paper extraction mechanism 3 can be driven to a specified position, and after the paper extraction mechanism 3 clamps the invoice, the second connecting rod 27 can be made to obtain a larger deflection angle through the transverse slide groove 19 to remove the invoice from the paper pickup wheel 15. After the invoice is removed, the reciprocating mechanism 2 can be reset by the movement of the reciprocating screw 24, and the paper extraction mechanism 3 can also be reset; the reciprocating screw 24 can be used to reset the paper extraction mechanism 3 after it runs to the invoice size, so that the invoice enters the sorting mechanism 4. In order to cope with the situation that the size of some special invoices is different from that of ordinary invoices, the moving distance of the push connecting block 25 can be adjusted by replacing the reciprocating screw 24, and the moving distance of the paper extraction mechanism 3 can be indirectly adjusted, thereby adapting to invoices of different sizes.

[0036] Specifically, the sorting mechanism 4 includes a sorting frame 41, the bottom of which is fixedly connected to the scanner housing 1, a transmission unit 42 is arranged inside the sorting frame 41, a fixing frame 43 is fixedly connected to the top of the sorting frame 41, a laser scanner is arranged on the side of the fixing frame 43 facing the transmission unit 42, and rolling wheels are rotatably connected to both sides of the fixing frame 43; a flip motor is arranged inside the sorting frame 41, a flip plate 44 is fixedly connected to the output end of the flip motor, and the bottom of the flip plate 44 is in contact with the surface of the invoice.

[0037] In this embodiment, it is considered that most of the prior art processes invoices by rolling them with rollers, and the rolling method can usually only flatten wrinkles. In the case of an invoice with a folded corner, the folded corner needs to be larger in angle to be spread out, and the folded invoice cannot be spread out. If the folded corner is small or close to the invoice, the folded corner may be compacted by the roller, resulting in a deeper fold at the folded corner of the invoice, which may affect the scanning recognition; it is considered that some prior art uses a sheet-like rod to fit the invoice to spread the folded corner, but if the folded corner is compacted and the fold is deep, the fold may be torn due to excessive force; and the prior art usually only sorts the invoice in one direction, and when the folded corner or the folded direction is opposite to the sorting direction, the invoice cannot be scanned; When the invoice leaves the paper extraction mechanism 3, it moves from the tail end toward the sorting mechanism 4. When the invoice falls on the transmission unit 42, it will be transferred to the fixed frame 43. When the invoice passes through the flip plate 44, the flip plate 44 will fit with the surface of the invoice. When the flip plate 44 encounters the folded corner of the invoice, it will be blocked by the folded corner. At this time, the laser scanner on the fixed frame 43 detects that the flip plate 44 is blocked and starts the flip motor, and the flip motor drives the flip plate 44 to flip, so that the folded corner is spread out while the flip plate 44 flips, thereby avoiding the crease from being stressed while spreading the folded corner, ensuring the integrity of the invoice. After the folded corner is processed, the invoice is flattened by the rolling wheel to ensure that the invoice will not have wrinkles. When the folded corner of the invoice or the folding direction is opposite to the transportation direction of the transmission unit 42, the invoice cannot be sorted normally. However, after the invoice is re-detected by the collecting mechanism 5, it will re-enter the sorting mechanism 4. At this time, the tail of the invoice will be clamped by the paper extraction mechanism 3, and the head of the invoice will move toward the sorting mechanism 4. At this time, the opposite folded corner can be spread out.

[0038] Specifically, the collecting mechanism 5 includes a collecting lower shell 51 and a collecting box 52. The collecting lower shell 51 is located below the collecting box 52. A lifting air pump 53 is provided at the center of the bottom of the inner wall of the collecting lower shell 51. Air outlets are provided on both sides of the lifting air pump 53. The air outlets are fixedly connected to a pneumatic shell 54. A pneumatic rod 55 is slidably connected to the inner wall of the pneumatic shell 54. The top of the pneumatic rod 55 is fixedly connected to the bottom of the collecting box 52. The top of the pneumatic rod 55 is connected to the collecting box 52, and the bottom of the pneumatic rod 55 is connected to the pneumatic shell 54. The bottom of the inner wall of the box 52 is fixedly connected to multiple groups of first lifting shells 57 and second lifting shells 58, the inner wall of the first lifting shell 57 is slidably connected to the first lifting rod 571, and the inner wall of the second lifting shell 58 is slidably connected to the second lifting rod 581. The length of the first lifting rod 571 is shorter than the second lifting rod 581, and the tops of the first lifting rod 571 and the second lifting rod 581 are fixedly connected to the collecting plate 59. The first lifting shell 57 is closer to the sorting mechanism 4 than the second lifting shell 58; the outer wall of the collecting plate 59 is slidably connected to the inner wall of the collection box 52.

[0039] In this embodiment, considering that the prior art usually organizes invoices while scanning invoices, subsequent invoices need to wait until the organization is completed before they can enter during invoice organization, which greatly affects the efficiency of invoice scanning; after the invoice is flattened, the invoice will be transferred to the collection mechanism 5 for collection through the transmission unit 42, and the invoice will be collected by the collection box 52 and the collection plate 59. After the monitor 18 detects that no invoices enter the paper pickup wheel 15, the lifting air pump 53 is started to inflate the inside of the pneumatic housing 54 on both sides, and the airflow pushes the limit plate so that the pneumatic rod 55 can move upward, and at this time the pneumatic rod 55 will push the collection box 52 to move upward; when the airflow enters the pneumatic housing 54, the pneumatic rod 55 can be used to inflate the inside of the collection box 52, and at this time the airflow will push the collection plate 59 to move, and the movement of the collection plate 59 can drive The first lifting rod 571 and the second lifting rod 581 move upward, but because the first lifting rod 571 is shorter than the second lifting rod 581, the second lifting rod 581 is still moving upward when the first lifting rod 571 rises to the top, and the collecting plate 59 can be tilted at this time. The invoice inside can be tilted by the inclination of the collecting plate 59, and the invoice will move toward the side of the first lifting rod 571. Since one side of the transfer plate 13 is blocked, the invoice will not fall out when it moves, and the invoice will be aligned according to the inclination direction. When the collection box 52 rises to the top, the invoice will move toward the baffle 14 due to the inclination; through the above operation, the device can automatically operate to perform a second scan on the sorted invoices in the collection box 52 when it detects that no invoices are transmitted from the paper pickup wheel 15, and will perform a second sorting when it is detected that there is still a problem with the invoice.

[0040] Specifically, an inclined block 312 is provided on the top of the paper-drawing housing 31 , and the inclined block 312 contacts the stop plate 151 .

[0041] In this embodiment, considering that the paper-drawing shell 31 needs to rely on the adjustment motor 311 to rotate when it moves, when the equipment malfunctions and causes the rotation angle to be too large, the direction of the paper clamping port 32 may not be aligned with the sorting mechanism 4, which may cause the invoice to be unable to be delivered normally; the setting of the inclined block 312 can not only make the paper-drawing shell 31 blocked by the stop plate 151 after rotating to the specified angle, but also align the paper clamping port 32 with the sorting mechanism 4 by limiting the position and angle, thereby preventing excessive deflection, and at the same time, the direction of the invoice can be guided by the inclination of the top of the inclined block 312.

[0042] Specifically, a throttle block is disposed inside the pneumatic rod 55, and the throttle block is used to throttle the airflow.

[0043] In this embodiment, it is considered that when the collecting plate 59 rises to the top in the initial stage, the invoice will not be blocked by the collecting box 52, and since the collecting plate 59 will be tilted, the invoice may fall; the airflow can be slowed down or blocked by the setting of the throttle block, thereby reducing the airflow. When the pneumatic rod 55 pushes the collecting box 52 to the top, the throttle block is completely released to prevent the collecting plate 59 from rising too fast in the initial stage.

[0044] Specifically, a spline shaft 56 is fixedly connected to the bottom of the inner wall of the collecting lower shell 51 , and one end of the spline shaft 56 away from the collecting lower shell 51 is fixedly connected to the collecting box 52 .

[0045] In this embodiment, the spline shaft 56 can be provided to support the collecting box 52. The characteristics of the spline shaft 56 can limit the collecting box 52 during its rise to prevent it from being out of position.

[0046] Specifically, a plurality of rotating holes are provided on the top of the transmission plate 13, and rollers 132 are rotatably connected in the rotating holes. The center of the rollers 132 is lower than the top surface of the transmission plate 13, and a first pressing block 131 is fixedly connected to the top of the transmission plate 13; a second pressing block 141 is fixedly connected to the bottom of the baffle 14.

[0047] In this embodiment, when the invoice is on the transmission plate 13, the roller 132 will slide the invoice toward the baffle 14 and be blocked by the baffle 14. While rubbing the paper, the first pressing block 131 and the second pressing block 141 can be set to unfold the folded corner of the tail of the invoice during rubbing the paper, so as to avoid the failure of recording due to the folded corner during recording. When the collecting plate 59 transmits the invoice, the invoice can be moved to the baffle 14 through the roller 132. At the same time, considering that the stacked invoices will produce pressure on the invoice at the bottom, the invoice at the bottom will not be able to move above the roller 132, thereby causing the invoice at the bottom to be unable to move normally to the baffle 14. At this time, due to the characteristic that the center of the roller 132 is lower than the top surface of the transmission plate 13, the part of the roller 132 on the top surface of the transmission plate 13 is lower, so that the invoice can be moved normally from the roller 132 while avoiding being stuck by the roller 132.

[0048] When using, First, when entering the invoice, the invoice is stacked and put in from the feed port 11. After the invoice is put in, it will fall on the top of the transfer plate 13. Since the transfer plate 13 itself is inclined, when the invoice is on the transfer plate 13, the roller 132 will slide the invoice toward the baffle 14 and be blocked by the baffle 14. At this time, the paper pickup motor is started to drive the paper pickup wheel 15. When the paper pickup wheel 15 rotates, it will rub the invoice at the bottom to the transmission unit 16. While rubbing the paper, the first pressing block 131 and the second pressing block 141 are set to fit the invoice when rubbing the paper and unfold the folded corner at the tail of the invoice to avoid the folded corner causing the entry failure.

[0049] Secondly, when problems such as paper jam or invoice corner folding are detected, the reciprocating motor 22 is started, and the reciprocating motor 22 drives the reciprocating screw 24 to rotate. At this time, the fixed slider 23 slides in the thread of the reciprocating screw 24. Since the fixed slider 23 is fixed, the reciprocating screw 24 rotates while driving the connecting block 25 to move. When the reciprocating screw 24 moves, the reciprocating motor 22 also moves with it, and the connecting block 25 pulls one end of the first connecting rod 26 to move, and slides through the horizontal slide groove 19 at the hinge between the first connecting rod 26 and the second connecting rod 27. The second connecting rod 27 can have a larger deflection angle and a larger lateral movement space to avoid the second connecting rod 27 from sliding. During the rotation of 27, it is stuck with the transmission unit 16, causing the device to fail to operate normally. At this time, the second connecting rod 27 can be rotated by the rotating rod. The position of the paper extraction mechanism 3 can be controlled by rotating the second connecting rod 27, and the angle of the paper extraction mechanism 3 can be controlled by adjusting the motor 311. Therefore, when encountering a paper jam, the paper extraction mechanism 3 can be driven to a specified position, and after the paper extraction mechanism 3 clamps the invoice, the second connecting rod 27 can be made to obtain a larger deflection angle through the transverse slide groove 19 to remove the invoice from the paper pickup wheel 15. After removal, the reciprocating mechanism 2 can be reset by the movement of the reciprocating screw rod 24, and the paper extraction mechanism 3 can also be reset.

[0050] At the same time, when the invoice is jammed due to misalignment, or when the monitor 18 finds that the invoice has corners and wrinkles, the paper pickup motor will stop driving the paper pickup wheel 15 to rotate. At this time, the invoice will slide onto the stop plate 151, and the paper extraction mechanism 3 will be lifted by the reciprocating mechanism 2, and the paper extraction housing 31 will be rotated by adjusting the motor 311, and the paper clamping port 32 will be parallel to the top surface of the stop plate 151 to ensure that the invoice can fall into the paper clamping port 32. The position of the paper clamping paper 33 can be controlled by the setting of the traction rod 36. When in use, the electric telescopic rod 34 is started to retract the part that has been extended into the paper extraction housing 31, and the traction rod 36 can be pulled by the synchronous movement of the adjustment rod 35 and the electric telescopic rod 34. Since the position of one end of the traction rod 36 connected to the hinge block 37 is fixed, and the other end of the traction rod 36 is in contact with the paper clamping paper 33, the traction rod 36 will be pushed to approach each other when being pulled, so as to achieve the effect of clamping the invoice. After the paper extraction mechanism 3 is moved to the maximum size of the invoice by the reciprocating mechanism 2, the electric telescopic rod 34 moves into the paper extraction housing 31 so that the traction rod 36 releases the clamping paper board 33 under the pull of the adjusting rod 35. At this time, the clamping paper board 33 can be pulled back by the reset spring 331, thereby releasing the clamping of the invoice, and the invoice will slide down to the inside of the sorting mechanism 4 through the inclined paper extraction housing 31; through the above method, no manual operation is required to handle paper jams, and the paper jams can be re-sorted through the sorting mechanism 4 after pulling out the paper jams, which can reduce the time for manual handling of paper jams or paper wrinkles.

[0051] Then, when the invoice leaves the paper extraction mechanism 3, it moves from the tail end toward the sorting mechanism 4. When the invoice falls on the transmission unit 42, it will be transferred to the fixed frame 43. When the invoice passes through the flip plate 44, the flip plate 44 will fit with the surface of the invoice. When the flip plate 44 encounters the folded corner of the invoice, it will be blocked by the folded corner. At this time, the laser scanner on the fixed frame 43 detects that the flip plate 44 is blocked and starts the flip motor, and the flip motor drives the flip plate 44 to flip, so that the folded corner is spread out while the flip plate 44 flips, thereby avoiding the crease from being stressed while spreading the folded corner, ensuring the integrity of the invoice. After the folded corner is processed, the invoice is flattened by the rolling wheel to ensure that the invoice will not have wrinkles. When the folded corner of the invoice or the folding direction is opposite to the transportation direction of the transmission unit 42, the invoice cannot be sorted normally, but the invoice will be re-detected by the collecting mechanism 5 and will re-enter the sorting mechanism 4. At this time, the tail of the invoice will be clamped by the paper extraction mechanism 3, and the head of the invoice will move toward the sorting mechanism 4. At this time, the opposite folded corner can be spread out.

[0052] Finally, after the invoice is flattened, it will be transferred to the collection mechanism 5 for collection through the transmission unit 42, and the invoice will be collected by the collection box 52 and the collection plate 59. After the monitor 18 detects that there is no invoice entering the paper pickup wheel 15, the lifting air pump 53 is started to inflate the inside of the pneumatic shells 54 on both sides, and the airflow pushes the limit plate so that the pneumatic rod 55 can move upward. At this time, the pneumatic rod 55 will push the collection box 52 to move upward; when the airflow enters the pneumatic shell 54, the airflow can be used to inflate the inside of the collection box 52 through the pneumatic rod 55. At this time, the airflow will push the collection plate 59 to move, and the movement of the collection plate 59 The movement can drive the first lifting rod 571 and the second lifting rod 581 to move upwards. However, since the first lifting rod 571 is shorter than the second lifting rod 581, the second lifting rod 581 is still moving upwards when the first lifting rod 571 rises to the top. At this time, the collecting plate 59 can be tilted. The tilt of the collecting plate 59 can make the invoice inside tilt. At this time, the invoice will move to the side of the first lifting rod 571. Since one side of the transfer plate 13 is blocked, the invoice will not fall out when it moves. At the same time, the invoice will be aligned according to the tilt direction. When the collection box 52 rises to the top, the invoice will move toward the baffle 14 due to the tilt. When the collecting plate 59 passes the invoice up, the invoice can be moved to the baffle 14 through the roller 132. At this time, due to the characteristic that the center of the roller 132 is lower than the top surface of the transmission plate 13, the part of the roller 132 on the top surface of the transmission plate 13 is lower, so that the invoice can be moved from the roller 132 normally while avoiding being stuck by the roller 132. After the invoice is transferred to the scanner 17 through the transmission unit 16 and scanned, it is collected by the collection rack 12 to facilitate subsequent filing and sorting.
