Description

Technical Field

[0001] This invention relates to a card sealing machine, specifically to a bagging system and a card sealing machine. Background Technology

[0002] In the bulk mailing of personalized cards (bank cards, social security cards, etc.) in the financial and telecommunications fields, card sealing machines are the core equipment to ensure card security and information integrity. They integrate information processing and sealing functions, significantly improving the efficiency and reliability of card mailing.

[0003] The existing card mailing machine operates as follows: First, the built-in card reader module reads personalized data such as the card's account and user association information; second, the control system uses this data to retrieve mailing information and drives the printing unit to print onto an A4 mailing medium (instruction manual, notification slip, etc.); third, the mailing medium is conveyed by a sorting and conveying mechanism, precisely aligned with the card, and affixed; fourth, a folding mechanism folds the affixed material, and finally, it is placed into an envelope along with the promotional leaflet to complete the sealing process.

[0004] In the combined bagging of cards, instruction manuals, and brochures, the envelopes must first be transported to the conveyor line via an envelope feeding device, and then transferred to the bagging station for material filling. Traditional bagging systems generally use conveyor belts to transport the envelopes, but this method has significant technical defects: due to the unstable surface friction characteristics of the conveyor belt and the lack of precise positioning constraints during transport, the transport accuracy of the envelopes is easily insufficient, causing deviations in their spatial position or posture when they arrive at the bagging station. These deviations directly prevent the pushing device from accurately pushing the stacked cards, instruction manuals, and brochures into the envelopes, leading to bagging failures, material jamming, and other problems, seriously affecting the efficiency and stability of the bagging operation. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a bagging system that can achieve precise bagging, thereby improving bagging efficiency.

[0006] A second objective of this invention is to provide a card mailing machine employing the above-described bagging system.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0008] A bagging system includes a frame, an envelope feeding device mounted on the frame, a first conveyor line for conveying envelopes from the envelope feeding device to a bagging station, a second conveyor line for conveying bags to be bagged to the bagging station, and a bagging device for opening the envelopes at the bagging station and feeding the bags to be bagged into the envelopes.

[0009] The first conveyor line and the second conveyor line are arranged in parallel. The first conveyor line includes a conveyor belt, clamping members disposed on the conveyor belt, and a conveying drive mechanism for driving the conveyor belt to circulate vertically.

[0012] When the clamping member reaches the loading station, the clamping drive mechanism causes the clamping member to open. After the envelope bag loading device sends the envelope bag to the loading station, the clamping push mechanism pushes the envelope bag to move so that one side of the envelope bag is located at the clamping opening of the clamping member. The clamping drive mechanism then drives the clamping member to close again to clamp the envelope bag.

[0013] Preferably, the clamping member includes a first clamping block and a second clamping block hinged to the first clamping block, wherein a compression spring is provided between the first clamping block and the second clamping block, and the elastic force of the compression spring causes the first clamping block and the second clamping block to be in a closed state.

[0014] Preferably, the clamping drive mechanism includes a bracket, a pressure block disposed on the bracket, and a clamping cylinder for driving the pressure block to move, wherein the cylinder body of the clamping cylinder is mounted on the bracket, and the piston rod of the clamping cylinder is connected to the pressure block; the pressure block is located above the clamping member.

[0015] Preferably, the clamping and pushing mechanism includes a push block and a pushing cylinder for driving the push block to move along the conveying direction of the conveyor belt, wherein the pushing cylinder is mounted on the frame and the push block is mounted on the piston rod of the pushing cylinder.

[0016] Preferably, a guiding device for guiding the opening of the sealing flap of the envelope is further provided between the envelope feeding device and the bagging device; the guiding device includes a guiding component and a pressing component, wherein the guiding component is used to guide the opening of the sealing flap of the envelope during the movement of the envelope; and the pressing component is used to guide the envelope to reach the bagging station with the sealing flap open.

[0017] Preferably, the guide is a guide plate that extends obliquely upward along the conveying direction of the first conveyor line. The side of the guide plate away from the second conveyor line gradually twists upward toward the direction of the second conveyor line during the extension process to guide the sealing flap of the envelope moving in the second conveyor line to flip outward. The gap between the guide plate and the conveying plane of the first conveyor line forms a first conveying channel.

[0018] Preferably, the pressing element is a pressing plate, which is horizontally arranged on the frame and extends along the conveying direction of the first conveyor line. There is a second conveying channel between the pressing plate and the conveying plane of the first conveyor line, through which the envelope can pass with its seal open. The second conveying channel is connected to the first conveying channel. The pressing plate is provided with an upwardly inclined guide at the inlet of the second conveying channel to guide the envelope into the second conveying channel with its seal open.

[0019] Preferably, the frame is provided with an air blowing assembly, which is located above the guide plate, and the air blowing nozzle of the air blowing assembly is tilted towards the guide plate to cause the sealing flap of the envelope bag entering the first conveying channel to open outward.

[0020] Preferably, the bagging device includes an opening mechanism for opening the envelope and a filling mechanism for pushing the items to be bagged into the envelope, wherein,

[0021] The bag-opening mechanism includes a support plate, an upper suction assembly, a lower suction assembly, and a bag-opening drive mechanism for driving the upper and lower suction assemblies to move relative to each other. The support plate is installed at the bagging station, with its upper surface flush with the conveying plane of the second conveyor line and its lower surface higher than the conveying plane of the first conveyor line. The gap between the support plate and the conveying plane of the first conveyor line forms a third conveying channel. The third conveying channel communicates with the second conveying channel, and its height is greater than or equal to the height of the second conveying channel. The upper suction assembly is located above the bagging station, and the lower suction assembly is located below the bagging station.

[0022] The filling mechanism includes a pusher plate and a filling drive mechanism for driving the pusher plate to move and push the bags to be filled on the second conveyor line into the envelopes located in the filling station. The support plate is provided with grooves for avoiding the pusher plate. The grooves extend in a straight line along the conveying direction perpendicular to the first conveyor line / second conveyor line.

[0023] Preferably, the envelope feeding device consists of two sets, which are arranged in parallel to send envelopes of different sizes. Each set of envelope feeding devices includes an envelope storage mechanism and an envelope feeding mechanism for taking out the envelopes from the envelope storage mechanism and transferring them to the feeding station.

[0024] A card mailing machine, including the bagging system described above.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] 1. The bagging system of the present invention uses a clamping component on a conveyor belt. The clamping component is opened by a clamping drive mechanism located at the loading station. Then, the envelope bag located at the loading station is pushed into the clamping opening of the clamping component by a clamping push mechanism. The clamping drive mechanism then drives the clamping component to close again, thereby clamping the envelope bag. By adopting this clamping and conveying method, not only can the conveying accuracy be improved, thus accurately delivering the envelope bag to the bagging station, but other processes can also be performed on the envelope bag during the conveying process, such as opening the sealing flap of the envelope bag.

[0040] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0041] Example 1

[0042] See Figures 1-18 The bagging system of the present invention includes a frame 1, an envelope feeding device 2 disposed on the frame 1, a first conveyor line 5 for conveying the envelopes issued by the envelope feeding device 2 to the bagging station, a second conveyor line 6 for conveying the bags to be bagged to the bagging station, and a bagging device for opening the envelopes at the bagging station and feeding the bags to be bagged into the envelopes.

[0043] The first conveyor line 5 and the second conveyor line 6 are arranged in parallel. The first conveyor line 5 includes a conveyor belt, clamping members disposed on the conveyor belt, and a conveying drive mechanism for driving the conveyor belt to circulate vertically.

[0044] The clamping components are in multiple sets, and the multiple sets of clamping components are arranged along the conveying direction of the conveyor belt;

[0045] The frame 1 is provided with a clamping drive mechanism 7 for driving the clamping member to open or close, and a clamping push mechanism for pushing the envelope into the clamping opening of the clamping member in the open state at the feeding station of the envelope feeding device 2.

[0046] When the clamping member reaches the loading station, the clamping drive mechanism 7 causes the clamping member to open. After the envelope bag loading device 2 sends the envelope bag to the loading station, the clamping push mechanism pushes the envelope bag to move so that one side of the envelope bag is located at the clamping opening of the clamping member. The clamping drive mechanism 7 then drives the clamping member to close again to clamp the envelope bag.

[0047] In this embodiment, the second conveyor line 6 can be implemented with reference to the structure of the first conveyor line 5, or it can be implemented using an existing conveyor belt conveying mechanism.

[0048] See Figures 1-18 The clamping member includes a first clamping block 501 and a second clamping block 502 hinged to the first clamping block 501, wherein the second clamping block 502 is mounted on the conveyor belt; a compression spring is provided between the first clamping block 501 and the second clamping block 502; the elastic force of the compression spring causes the first clamping block 501 and the second clamping block 502 to be in a closed state; when it is necessary to open the clamping opening of the clamping member, it is only necessary to drive the tail of the first clamping block 501 to move downward against the elastic force of the compression spring, so that the clamping parts of the first clamping block 501 and the second clamping block 502 are separated, thereby opening the clamping opening of the clamping member; when the downward force applied to the tail of the first clamping block 501 disappears, under the elastic force of the compression spring, the tail of the first clamping block 501 moves upward, so that the clamping parts of the first clamping block 501 and the second clamping block 502 are closed, thereby closing the clamping opening of the clamping member.

[0049] See Figures 1-18 The clamping drive mechanism 7 includes a bracket, a pressure block 702 mounted on the bracket, and a clamping cylinder 701 for driving the pressure block 702. The cylinder body of the clamping cylinder 701 is mounted on the bracket, and the piston rod of the clamping cylinder 701 is connected to the pressure block 702. The pressure block 702 is located above the clamping member. When the clamping member moves directly below the pressure block 702, the clamping cylinder 701 drives the pressure block 702 to move downward to open the clamping opening of the clamping member. When the clamping push mechanism pushes the envelope bag at the loading station to the clamping opening of the clamping member, the clamping cylinder 701 drives the pressure block 702 to move upward to close the clamping opening of the clamping member, thereby clamping one side of the envelope bag.

[0050] See Figures 1-18 The clamping and pushing mechanism includes a pusher block 503 and a pushing cylinder for driving the pusher block 503 to move along the conveying direction of the conveyor belt. The pushing cylinder is mounted on the frame 1, and the pusher block 503 is mounted on the piston rod of the pushing cylinder. A second clearance groove for avoiding the pusher block 503 is provided on the conveying plane of the first conveyor line 5. With the above configuration, when the envelope bag feeding device 2 sends the envelope bag to the feeding station, the pushing cylinder drives the pusher block 503 to move, thereby pushing the envelope bag into the clamping opening of the clamping member.

[0051] See Figures 1-18A guiding device 3 for guiding the opening of the sealing flap of the envelope is also provided between the envelope feeding device 2 and the bagging device; the guiding device 3 includes a guiding component and a clamping component, wherein the guiding component is used to guide the sealing flap of the envelope to open during the movement of the envelope; the clamping component is used to guide the envelope to reach the bagging station with the sealing flap open.

[0052] The guide is a guide plate 301, which extends obliquely upward along the conveying direction of the first conveyor line 5. During the extension process, the side of the guide plate 301 away from the second conveyor line 6 gradually twists upward toward the direction of the second conveyor line 6 to guide the sealing flap of the envelope moving in the second conveyor line 6 to flip outward. The gap between the guide plate 301 and the conveying plane of the first conveyor line 5 forms a first conveying channel.

[0053] The pressing component is a pressing plate 302, which is horizontally arranged on the frame 1 and extends along the conveying direction of the first conveyor line 5. There is a second conveying channel between the pressing plate 302 and the conveying plane of the first conveyor line 5, through which the envelope can pass with its seal open. The second conveying channel is connected to the first conveying channel. The pressing plate 302 is provided with an inclined upward-extending guide at the inlet of the second conveying channel to guide the envelope into the second conveying channel with its seal open.

[0054] In this embodiment, an air blowing assembly 303 is provided on the frame 1. The air blowing assembly 303 is located above the guide plate 301, and the air blowing nozzle of the air blowing assembly 303 is tilted towards the guide plate 301 to cause the sealing tongue of the envelope bag entering the first conveying channel to open outward.

[0055] With the above configuration, the conveyor belt drives the clamping member and the envelope bag held by the clamping member to move. During the movement to the bagging station, the guide plate 301 guides the sealing flap of the envelope bag to fold outward. At the same time, the air blowing component 303 blows air downward at an angle to assist in causing the sealing flap of the envelope bag to fold outward. After the envelope bag passes through the first conveying channel, the envelope bag re-enters the second conveying channel with the sealing flap open, and then re-enters the third conveying channel in the same state.

[0056] See Figures 1-18 The bagging device includes an opening mechanism 9 for opening the envelope and a filling mechanism 4 for pushing the items to be bagged into the envelope.

[0057] See Figures 1-18The bag opening mechanism 9 includes a support plate, an upper suction assembly 901, a lower suction assembly 902, and a bag opening drive mechanism for driving the upper suction assembly 901 and the lower suction assembly 902 to move relative to each other.

[0058] The support plate is installed at the bagging station. The upper surface of the support plate is flush with the conveying plane of the second conveyor line 6, and the lower surface of the support plate is higher than the conveying plane of the first conveyor line 5. The gap between the support plate and the conveying plane of the first conveyor line 5 forms a third conveying channel. The second conveying channel is connected to the third conveying channel, and the height of the third conveying channel is greater than or equal to the height of the second conveying channel, so that the envelopes located in the second conveying channel can smoothly enter the third conveying channel.

[0059] The upper suction component 901 is located above the bagging station; the lower suction component 902 is located below the bagging station. In this embodiment, both the upper suction component 901 and the lower suction component 902 are composed of suction nozzles. The upper suction component 901 is mounted above the bagging station via a support frame; the lower suction component 902 is located below the bagging station. A third clearance groove for avoiding the lower suction component 902 is provided on the conveying plane of the first conveyor line 5.

[0060] The bag opening drive mechanism is used to drive the upper suction component 901 and the lower suction component 902 to rise and fall. The bag opening drive mechanism can be driven by cylinders, for example, two sets of cylinders (e.g., cylinder 903 and cylinder 904), where one set of cylinder 903 is used to drive the upper suction component 901 to rise and fall, and the other set of cylinder 904 is used to drive the lower suction component 902 to rise and fall.

[0061] With the above configuration, when it is necessary to open the opening of the envelope bag located at the bagging station, the bag opening drive mechanism drives the upper suction component 901 and the lower suction component 902 to rise and fall synchronously, and the upper suction component 901 and the lower suction component 902 rise and fall in opposite directions, so that the upper suction component 901 sucks up the upper side of the envelope bag, while the lower suction component 902 sucks up the lower side of the envelope bag. The bag opening drive mechanism drives the upper suction component 901 and the lower suction component 902 to move in opposite directions, thereby opening the envelope bag.

[0062] See Figures 1-18 The filling mechanism 4 includes a pusher plate 405 and a filling drive mechanism for driving the pusher plate 405 to move so as to push the bags to be filled on the second conveyor line 6 into the envelopes located in the filling station.

[0063] The support plate is provided with a groove 12 for avoiding the push plate 405; the groove 12 extends in a straight line along the conveying direction perpendicular to the first conveying line 5 / second conveying line 6;

[0064] The loading drive mechanism includes a mounting frame 401, a linear drive mechanism mounted on the mounting frame 401 for driving the push plate 405 to perform linear motion, and a lifting drive mechanism for driving the push plate 405 to perform lifting motion.

[0065] The linear drive mechanism includes a movable base 403 and a power drive mechanism for driving the movable base 403 to perform linear motion; the movable base 403 is mounted on the mounting bracket 401 via a linear sliding mechanism 407; the power drive mechanism includes a linear motor 402 and a synchronous belt drive mechanism; the push plate 405 is mounted on the movable base 403 via a vertical sliding mechanism 408, the vertical sliding mechanism 408 including a slide rail vertically arranged on the movable base 403 and a slider arranged on the slide rail; the push plate 405 is mounted on the slider.

[0066] The lifting drive mechanism includes an annular groove 409 disposed on the mounting bracket 401 and a roller 411 disposed within the annular groove 409. The synchronous belt 406 has a protrusion 410 with a through hole. The roller 411 is connected to the slider via a rotating shaft. One end of the rotating shaft is connected to the roller 411, and the other end passes through the through hole in the protrusion 410 and is rotatably connected to the slider. The annular groove 409 has the same circumferential direction as the synchronous belt 406. The synchronous belt drive mechanism is located within the annular groove 409.

[0067] With the above setup, after the envelope reaches the bagging station and is opened by the bag-opening mechanism 9, the linear motor 402 drives the synchronous belt transmission mechanism to work, causing the synchronous belt 406 to rotate cyclically. This drives the rotating shaft and the roller 411 and slider connected to the rotating shaft to move, thereby driving the moving seat 403 to move. When the roller 411 passes through the arc-shaped section of the annular groove 409 from bottom to top, the height of the roller 411 increases, thus driving the push plate 405 to move upward. When the roller 411 reaches the upper straight section of the annular groove 409, with the cyclical movement of the synchronous belt 406, the... The movable seat 403 can move in a straight line in the opposite direction. When the roller 411 passes through the arc-shaped section of the annular groove 409 from top to bottom, the height of the roller 411 decreases, which can drive the push plate 405 to move downward. When the roller 411 reaches the lower straight section of the annular groove 409, the movable seat 403 can continue to move in a straight line as the synchronous belt 406 circulates. Therefore, through the above movement, a closed-loop movement of the push plate 405 can be realized, which is downward movement - straight line movement (forward) - upward movement - straight line movement (reverse), thereby pushing the bag to be filled into the envelope to complete the bagging work.

[0068] In this embodiment, there are two sets of push plates 405, both sets of push plates 405 are mounted on the mounting base 404, and the mounting base 404 is mounted on the slider. Correspondingly, there are also two sets of grooves 12.

[0069] In addition, the bagging station is also equipped with multiple sets of guide plates 11. The multiple sets of guide plates 11 extend horizontally along the conveying direction perpendicular to the first conveyor line 5 / second conveyor line 6. The guide plate 11 is composed of a first horizontal section, an inclined section and a second horizontal section. One end of the first horizontal section is slidably connected to the outside of the second conveyor line 6, and after passing over the second conveyor line 6, it connects to the upper end of the inclined section. The lower end of the inclined section is connected to the second horizontal section, which passes over the first conveyor line 5. The guide plates 11 are used to guide the bags to be packaged smoothly into the envelopes.

[0070] In addition, a clamping drive mechanism 7 is also provided at the bagging station, which is used to drive the clamping component to release the envelope. Positioning mechanisms are provided on both sides of the bagging station to position the envelope on both sides, thereby adjusting the position and posture of the envelope. Correspondingly, a detection module 13 is provided above the bagging station to detect the position and posture of the envelope at the bagging station. The positioning mechanism includes a positioning plate 905 and a positioning drive mechanism for driving the positioning plate 905. The positioning drive mechanism can be driven by a cylinder. A fourth clearance groove is provided on the conveying plane of the first conveyor line 5 to avoid the positioning plate 905, driven by the positioning drive mechanisms on both sides. The positioning plate 905 tilts upward synchronously, causing it to extend from the fourth clearance groove and correct the position of the envelope at the bagging station. The detection module 13 can use laser positioning or visual positioning. Before positioning, the clamping drive mechanism 7 needs to drive the clamping member to release the clamped envelope, and then position the envelope. During this process, since the displacement of the envelope is very small, one side of the envelope is always within the clamping range of the clamping member. Therefore, after bagging is completed, the clamping drive mechanism 7 releases the clamping member, and the clamping member can clamp one side of the envelope without the need for a separate clamping push mechanism.

[0071] See Figures 1-18 The envelope feeding device 2 consists of two sets, arranged side-by-side, for feeding envelopes of different sizes. Each set includes an envelope storage mechanism 201 and an envelope feeding mechanism 202 for removing envelopes from the storage mechanism 201 and transferring them to the feeding station. Since the two different envelopes have different sizes, multiple sets of limiting blocks 8 and a limiting drive mechanism for driving the limiting blocks 8 to move up and down are provided on the conveying plane of the first conveyor line 5. The multiple sets of limiting blocks 8 are arranged equidistantly along the conveying direction of the first conveyor line 5. A fifth clearance groove is provided on the conveying plane of the first conveyor line 5 to avoid the limiting blocks 8. The limiting drive mechanism drives the limiting blocks 8 to move upwards, thereby limiting the size of the smaller envelopes.

[0072] With the above settings, when a smaller envelope is used, the limiting drive mechanism drives the limiting block 8 to move upward, thereby forming a first conveyor line 5 with a width matching the smaller envelope, so as to convey the smaller envelope; when a larger envelope is used, the limiting drive mechanism drives the limiting block 8 to move downward, so as to convey the larger envelope.

[0073] In this embodiment, the limiting drive mechanism can be driven by a cylinder. There can be multiple sets of the limiting drive mechanism, and each set of the limiting drive mechanism is used to drive one or more sets of limiting blocks 8 to rise and fall.

After the card attaching operation is completed, the instruction manual with the card is transported to the second folding station. The second folding device F completes the second fold based on another preset fold line on the instruction manual. The instruction manual with the card after the second fold is then transported to the delivery station, where the delivery device G places paper (e.g., a brochure) onto its surface.
