Description

Technical Field

[0001] The present invention relates to a multi-link chain paper processing mechanism, which is mainly used in the field of chain paper bill processing and is suitable for application scenarios where a large number of bills need to be processed in a short time, such as splitting, stamping, and retaining. Background Art

[0002] At present, most of the bills used (such as VAT invoices) are multi-part continuous bills with chain holes on both sides. There are paper teeth between each part to lock each other (to ensure that the paper will not loosen during printing), each part is connected to each other (with a tear line between each part), and the distance and number between the upper and lower chain holes of the chain hole paper are uniformly determined (the distance between every 2 chain holes is 0.5 inches). It is usually necessary to tear the bill at the tear line, stamp each part, and classify it (customer copy, retained copy).

[0003] At present, various bills are widely used. When people process bills, they need to put blank bills into the printer for printing first, tear them along the tear line after printing, and then separate each copy for stamping, classification, etc. Not only are the process flows complicated, but also the work is repetitive and the work efficiency is low. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a multi-link chain paper processing mechanism, which can be used independently of the printer to realize continuous separation, stamping and retention processes, greatly improving the speed of paper processing. It is not only not affected by the printing speed and complex structure, but also can reduce costs and improve work efficiency.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a multi-link chain paper processing mechanism, which comprises:

[0006] frame;

[0007] A paper conveying component adapted to convey multiple copies of paper forward;

[0008] A paper cutting component, the paper cutting component comprising a transverse cutting component adapted to cut the multi-ply paper conveyed to the transverse cutting position in the transverse direction and a vertical cutting component adapted to cut the multi-ply paper conveyed in the vertical direction;

[0009] A paper separation component suitable for separating multiple sheets of paper after cutting;

[0010] A stamping component is suitable for stamping at least part of the separated papers.

[0011] Furthermore, in order to facilitate the collection of paper scraps after the paper cutting process by the paper cutting component, the multi-link chain paper processing mechanism also includes:

[0012] A paper scrap collecting component is suitable for collecting paper scraps after the paper cutting component cuts.

[0013] Furthermore, the multi-link chain paper processing mechanism also includes:

[0014] A retention mechanism is suitable for retaining paper after the separation process.

[0015] Furthermore, in order to properly separate the multiple copies of paper, the paper separation component includes:

[0016] A paper feeding roller connected to the frame and adapted to be driven to rotate;

[0017] The paper rubbing device comprises a rubbing paper board and a rubbing roller; wherein,

[0018] A paper pickup passage through which paper passes is formed between the paper feeding roller and the paper pickup board, and the paper pickup passage is suitable for self-adjusting its gap according to the thickness of the paper entering the paper pickup passage;

[0019] The pickup roller is movably connected to the pickup paper board and is suitable for rotating with the paper feed roller and the paper or being selectively driven to rotate.

[0020] Furthermore, one end of the pickup board in the paper feeding direction is hinged to the frame, and the pickup roller is arranged at the other end of the pickup board. The pickup board is suitable for swinging around the hinge under the action of the paper entering the pickup channel to self-adjust the gap of the pickup channel.

[0021] Further, the paper separation component further includes a pickup roller rotation driving mechanism connected to the pickup roller to drive the pickup roller to rotate, and the pickup roller rotation driving mechanism includes:

[0022] A main rotating shaft coaxially arranged with the hinged central axis of the rubbing board and connected to a rotating power source;

[0023] A secondary rotating shaft coaxially connected to the pickup roller;

[0024] A timing belt pair connects the main rotating shaft and the slave rotating shaft.

[0025] Furthermore, a torque limiter is provided in the transmission between the pickup roller rotation driving mechanism and the pickup roller.

[0026] Furthermore, the paper separation component further comprises a paper lifting roller adapted to be driven to rotate, in contact with the multiple sheets of paper and arranged before the pickup roller in the paper feeding direction; wherein the paper lifting roller and the pickup paper board are adapted to self-adjust the gap between them according to the thickness of the paper entering therebetween.

[0027] Furthermore, in order to improve the accuracy of paper cutting and avoid the occurrence of invalid tickets, sensors and driving components are also included;

[0028] The paper conveying component includes a paper drag chain assembly that cooperates with the chain holes of the multi-piece paper to link and deliver the multi-piece paper; wherein,

[0029] The sensor is inductively matched with the chain hole on the multi-ply paper, and the sensor is suitable for sensing the first part between the front end of the multi-ply paper and at least one chain hole on the multi-ply paper within a preset paper feeding length from the front end, so as to collect the length of the first part in the paper feeding direction; the front end of the multi-ply paper is the actual cutting position aligned with the transverse cutting component;

[0030] The driving component is connected to the paper conveying component. When the sensor senses the first part, the driving component drives the paper conveying component to move the multi-piece paper forward to increase or decrease a compensation length based on the preset paper feeding length so that the horizontal cutting component is aligned with the preset cutting position for the next cutting of the multi-piece paper.

[0031] Furthermore, it also includes a control circuit, which is connected to the sensor, the driving component and the transverse cutting component; wherein,

[0032] The control circuit is adapted to obtain the compensation length according to the acquired length of the first portion in the paper feeding direction, the internally preset or acquired distance between adjacent chain holes, and the internally preset length between the preset cutting position and the adjacent chain hole;

[0034] The control circuit is suitable for controlling the action of the transverse cutting assembly after the driving component drives the multi-piece paper to move forward to a preset cutting position where the transverse cutting assembly is aligned with the multi-piece paper for the next cutting.

[0035] After adopting the above technical solution, the present invention has the following beneficial effects:

[0036] 1. The multi-link chain paper processing mechanism of the present invention can be used independently without the printer. The multi-link paper printed by the printer is cut horizontally by the paper horizontal cutting component, and the paper is cut vertically by the vertical cutting component. The cut paper is processed separately. The separated paper needs to be stamped by the stamping component. The multi-link chain paper processing can quickly realize continuous separation, stamping and retention processes, greatly improving the speed of paper processing, not only being unaffected by its printing speed and complex structure, but also reducing costs and improving work efficiency;

[0037] 2. The present invention also uses deadweight to adjust the gap and pressure of the paper pickup channel. The paper pickup channel has a certain gap (allowing a small amount of paper to pass through), and the pickup paper board can be turned upward and rotated through a hinge fulcrum. When paper of different thicknesses enters the channel, the pickup paper board will be lifted to different heights, but the pressure on the paper is always the same (the paper pickup channel automatically adjusts the gap according to the different thicknesses of paper);

[0038] 3. In addition, the pickup paper board of the present invention can be turned upward at any time to open the pickup passage to handle paper jams. The hinge fulcrum and the pickup roller are transmitted by a synchronous belt, and the distance is relatively large, which will not affect the turning of the pickup paper board, and will not exert excess pressure on the pickup roller during the transmission of torque;

[0039] 4. A sensor is set to sense the first part between the front end of the multi-ply paper and at least one chain hole on the multi-ply paper within a preset paper feeding length from the front end, so as to collect the length of the first part in the paper feeding direction, and obtain the compensation length through the length of the first part and the distance between the two chain holes on the multi-ply paper. Then, during the next cutting, the driving component drives the paper conveying component to move the multi-ply paper forward to increase or decrease a compensation length based on the preset paper feeding length so that the transverse cutting component is aligned with the preset cutting position of the next cutting on the multi-ply paper, so as to achieve precise cutting and avoid the phenomenon of waste tickets.

[0053] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0054] like Figures 1 to 13 As shown, a multi-link chain paper processing mechanism comprises:

[0055] Rack 1;

[0056] A paper conveying component adapted to convey multiple sheets of paper 10 forward;

[0057] A paper cutting component, the paper cutting component includes a transverse cutting component 2 suitable for cutting the multi-piece paper 10 transported to the transverse cutting position in the transverse direction and a vertical cutting component 3 suitable for cutting the multi-piece paper 10 in the vertical direction during the transport process;

[0058] A paper separation component 4 adapted to separate the cut multi-part paper 10;

[0059] A stamping component 5 is suitable for stamping at least part of the separated paper sheets.

[0060] In this embodiment, the main structure of the paper conveying component is a conveying roller set 54. The conveying roller set 54 is a device used in the printer field, and this embodiment does not make too many redundant descriptions of its structure.

[0061] The transverse cutting assembly 2 and the vertical cutting assembly 3 may specifically be in the form of a power member, a transmission member and a cutter. This structure is commonly used by those skilled in the art, and this embodiment will not go into detail on the structure.

[0062] like Figure 1 As shown, the multi-link chain paper processing mechanism may also include:

[0063] A paper scrap collecting component 6 is suitable for collecting paper scraps after the paper cutting component cuts.

[0064] The paper scrap collecting component 6 can be implemented in the form of a paper scrap collecting box, which slides into the paper scrap collecting box through a channel after being cut.

[0065] like Figure 1 As shown, the multi-link chain paper processing mechanism may also include:

[0066] A storage mechanism 7 is suitable for storing the separated paper. The storage mechanism 7 can be a storage box, and of course, the storage of the corresponding paper can be achieved by designing a slide.

[0067] Specifically, the paper separation component 4 includes:

[0068] A paper feeding roller 41 connected to the frame and adapted to be driven to rotate;

[0069] The paper picking device includes a paper picking board 42 and a paper picking roller 43; wherein,

[0070] A paper pickup passage for paper to pass through is formed between the paper feeding roller 41 and the paper pickup paper 42, and the paper pickup passage is suitable for self-adjusting its gap according to the thickness of the paper entering the paper pickup passage;

[0071] The pickup roller 43 is movably connected to the pickup paper board 42 and is adapted to rotate with or be selectively driven to rotate driven by the paper feed roller 41 and the paper.

[0072] In this embodiment, the paper guide 20 is used to guide the advancing direction of the paper.

[0073] The clearance and pressure of the paper pickup channel are adjusted by the deadweight. The paper pickup channel has a certain clearance (allowing a small amount of paper to pass through), and the pickup paper board 42 can be turned upward and rotated through a hinge fulcrum. When paper of different thicknesses enters the channel, the pickup paper board 42 will be lifted to different heights, but the pressure on the paper is always the same (the paper pickup channel automatically adjusts the clearance according to the different thicknesses of paper);

[0074] like Figure 3 As shown, in order to realize the self-adjusting gap function of the paper pickup channel, one of the structural modes is introduced, one end of the paper pickup paper 42 in the paper feeding direction is hinged to the frame 1, and the paper pickup roller 43 is arranged at the other end of the paper pickup paper 42, and the paper pickup paper 42 is suitable for swinging around the hinge under the action of the paper entering the paper pickup channel to self-adjust the gap of the paper pickup channel.

[0075] The rubbing paper board 42 can also be flipped upward at any time to open the rubbing passage to handle paper jams. The hinged fulcrum and the rubbing roller are transmitted by a synchronous belt, and the distance is large, which will not affect the flipping of the rubbing paper board, and will not apply excess pressure to the rubbing roller during the transmission of torque.

[0076] Specifically, the paper separation component 4 further includes a pickup roller rotation driving mechanism connected to the pickup roller 43 to drive the pickup roller 43 to rotate. The pickup roller rotation driving mechanism may be the following structure, including:

[0077] A main rotating shaft 44a coaxially arranged with the hinge center axis of the rubbing board 42 and connected to a rotating power source;

[0078] A secondary rotating shaft 44b coaxially connected to the pickup roller 43;

[0079] A timing belt pair connects the main rotating shaft 44a and the slave rotating shaft 44b.

[0080] In this embodiment, the rotation power source drives the main rotating shaft 44 a to rotate, and the main rotating shaft 44 a drives the slave rotating shaft 44 b to rotate through the synchronous belt pair, and the slave rotating shaft 44 b further drives the pickup roller 43 to rotate.

[0081] In this embodiment, the synchronous belt pair includes a synchronous belt 45a, a main synchronous wheel and a slave synchronous wheel. The main synchronous wheel is connected to the main rotating shaft 44a, and the slave synchronous wheel is connected to the slave rotating shaft 44b.

[0082] A torque limiter 45 is provided in the transmission between the pickup roller rotation driving mechanism and the pickup roller 43 .

[0083] In this embodiment, the paper separation component 4 further includes a paper lifting roller 100 adapted to be driven to rotate, in contact with the multi-linked paper 10 and arranged before the pickup roller 43 in the paper feeding direction; wherein the gap between the paper lifting roller 100 and the pickup paper board 42 is adapted to be self-adjustable according to the thickness of the paper entering therebetween. The paper extraction roller is before the pickup roller 43, and the paper first passes through the paper extraction roller and then the pickup roller 43. The paper feed roller 41 and the paper lifting roller 100 are used to rotate counterclockwise to convey the paper, and the paper feed roller 41 and the paper lifting roller 100 are more stable and have a stronger paper separation capability.

[0084] Specifically, taking triple-joint paper as an example: the friction coefficient between the paper and the roller is μ 1 , the friction coefficient between paper and paper μ 2 The friction coefficient between the rollers is μ 3 , the positive pressure of the pickup paper board 2 is Fn, the radius of the pickup roller 3 is r, and a torque limiter 45 is provided between the pickup roller 43 and the secondary rotating shaft 44b, and its torque is T; the torque T is constant.

[0085] Friction force between paper and paper feed roller 41: f1 = μ 1 Fn;

[0086] Friction between paper and paper: f2 = μ 2 Fn;

[0087] Friction force between rollers: f3 = μ3Fn;

[0088] Torque of pickup roller 43: f4 = T / r;

[0089] Take three-part paper as an example. When three-part paper enters together, due to μ 1 >μ 2 That is, f1>f2, the paper feed roller 41 rotates counterclockwise to drive the third sheet of paper forward; when μ 2 When Fn<T / r (i.e. f2<f4), the third copy is separated, and the second copy is the same. When Fn is too large or T is too small, μ2Fn>T / r (i.e. f2>f4), three copies of paper are sent out together. This phenomenon is called double feeding and is an abnormal phenomenon. Figure 6 shown.

[0090] When there is no paper, the paper feed roller 41 rotates counterclockwise, and the paper feed roller 41 meshes with the paper pickup roller 43. Since μ3Fn>T / r (i.e. f3>f4), the friction between the rubber rollers is greater than the torque provided by the torque limiter, and the inner ring of the torque limiter slips, so the paper pickup roller 43 is driven by the paper feed roller 41 to rotate clockwise. Figure 4 shown.

[0091] When there is only one piece of paper, when μ 1 Fn>T / r (i.e. f1>f4), the paper feed roller 41 rotates counterclockwise to drive the paper forward. At this time, the friction between the paper and the rubber roller is greater than the constant torque provided by the torque limiter, the inner ring of the torque limiter slips, and the pickup roller 43 is driven by the paper to rotate clockwise. Figure 5 shown.

[0092] In summary, the matching relationship between Fn and T determines whether the paper can be fed out. The Fn of the traditional structure changes with the entry of paper of different thicknesses, and it is difficult to adjust the size of Fn; in this embodiment, Fn uses the deadweight of the sheet metal, so when different papers enter the channel, the size of Fn remains constant. Fig.13 shown.

[0093] In this embodiment, if Figures 7 to 12 As shown, the multi-link chain paper processing mechanism also includes a sensor 51 and a driving component;

[0094] The paper conveying component includes a paper drag chain assembly 52 that cooperates with the chain hole 10a of the multi-piece paper 10 to link and deliver the multi-piece paper 10; wherein,

[0095] The sensor 51 is inductively matched with the chain hole 10a on the multi-piece paper 10, and the sensor 51 is suitable for sensing the first part between the front end of the multi-piece paper 10 and at least one chain hole 10a on the multi-piece paper 10 within a preset paper feeding length from the front end, so as to collect the length of the first part in the paper feeding direction; the front end of the multi-piece paper 10 is the actual cutting position aligned with the transverse cutting component;

[0096] The driving component is connected to the paper conveying component. When the sensor 51 senses the first part, the driving component drives the paper conveying component to move the multi-piece paper 10 forward to increase or decrease a compensation length based on the preset paper feeding length so that the horizontal cutting component 2 is aligned with the preset cutting position for the next cutting of the multi-piece paper 10.

[0097] Fig.10 In the figure, A is the actual cutting position and B is the preset cutting position.

[0098] like Figure 7 As shown, the continuous paper 10 is a prior art paper, and a plurality of chain holes 10a are arranged in parallel on both sides along its length direction, that is, along the paper feeding direction. The distance and number between the upper and lower chain holes of the chain hole paper are uniformly determined, and the current standard distance between each adjacent chain hole 10a includes but is not limited to 0.5 inches.

[0099] In this embodiment, the sensor 51 includes but is not limited to a through-beam photoelectric sensor and a reflective photoelectric sensor, which are commonly used devices by those skilled in the art, and cooperate with the front end and the chain hole 10a of the continuous paper 10. During the movement of the continuous paper 10, when passing through the front end to the first chain hole 10a and the adjacent chain hole 10a, the light of the sensor 1 is blocked, and when passing through the chain hole 10a, the light of the sensor 1 is not blocked. In this way, the length from the front end to a certain chain hole 10a is obtained. The more chain holes 10a passed, the more accurate the length measurement is.

[0100] The multi-link chain paper processing mechanism further includes a control circuit, which is connected to the sensor 51, the driving component and the transverse cutting component 2; wherein,

[0101] The control circuit is adapted to obtain the compensation length according to the acquired length of the first portion in the paper feeding direction, the internally preset or acquired distance between adjacent chain holes, and the length between the internally preset preset cutting position and the adjacent chain hole 10a;

[0102] The control circuit is suitable for controlling the action of the driving component;

[0103] The control circuit is suitable for controlling the transverse cutting assembly 2 to move after the driving component drives the multi-piece paper 10 to move forward to a preset cutting position where the transverse cutting assembly 2 is aligned with the multi-piece paper 10 for the next cutting.

[0104] The driving component includes a motor as a driving source, the motor may be a stepping motor, and the control circuit controls the action of the stepping motor.

[0105] In this embodiment, the distance between adjacent chain holes 10a is preset inside the control circuit, or the distance between the chain holes 10a is collected in real time by the sensor 51. In the control circuit, the compensation length is obtained by obtaining the length of the first part in the paper feeding direction, the number of chain holes 10a passed through, the distance between adjacent chain holes 10a, and the preset cutting position preset inside and the length between adjacent chain holes 10a.

[0106] In this embodiment, the control circuit is a conventional physical device, and no improvement is made to its internal program.

[0107] Specifically, Fig.11 , 12 As shown, it is assumed that three chain holes 10a are passed from the front end, and the distance between the first chain hole 10a and the second chain hole 10a is L1;

[0108] The distance from the actual cutting position to the front end of the third chain hole is L2;

[0109] The distance from the preset cutting position to the front end of the first chain hole is L3;

[0110] The distance from the front end of the second chain hole 10a to the front end of the next chain hole is L4;

[0111] The required compensation length is L3-(L2-L1-L4). At this time, the motor will cooperate with the detection of the sensor 51 to compensate for the cut distance, and the motor controls the paper feeding, so there will be no cumulative error and the paper will not deviate as it is cut.

[0112] Specifically, Fig.10 As shown, the paper drag chain assembly 52 includes:

[0113] Chain rack 531;

[0114] A paper dragging chain 532 is movably arranged on the chain frame 531 and connected to the driving component to be driven to cyclically rotate. The outer ring of the paper dragging chain 532 has a protrusion 532a that is engaged with the chain hole 10a.

[0115] The driving component drives the paper drag chain 532 to rotate cyclically, and the chain hole 10a is fitted with the protrusion 532a, so that the multiple sheets of paper 10 are accurately positioned.

[0116] Other components in the paper drag chain assembly 52 are not described in detail in this embodiment.

[0117] Specifically, Figure 8 As shown, the paper conveying component further includes a conveying roller set 54, and the conveying roller set 54 is connected to the driving component to be driven.

[0118] The motor is connected to the conveying roller set 54;

[0119] The conveying roller assembly 54 is connected to the paper drag chain assembly 52;

[0120] The motor drives the conveying roller set 54 to move, and the conveying roller set 54 drives the paper drag chain assembly 52 to move synchronously.

[0121] The connection between the motor and the conveying roller set 54 and the connection between the conveying roller set 54 and the paper drag chain assembly 52 may also include some necessary intermediate transmission components.

[0122] like Fig. 9 As shown, the conveying roller set 54 is connected to the power input member of the paper dragging chain assembly 52 through a paper dragging synchronous belt pair 55 .

[0123] The synchronous belt pair 55 includes a main synchronous wheel, a slave synchronous wheel and a synchronous belt connecting the main synchronous wheel and the slave synchronous wheel. The main synchronous wheel is coaxially connected to one of the conveying rollers in the conveying roller group 54, and the slave synchronous wheel is connected to the power input member of the paper drag chain assembly 52.

[0124] Specifically, Fig. 9 As shown, the sensor 51 is disposed on one of the paper drag chain components 52 .
