Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to a layered conveying device for making and processing greeting cards and labels. Background Technology

[0002] In the field of greeting card printing and post-press processing, automated labeling production lines typically rely on sheet-separating conveyor devices to separate stacked cards one by one and feed them sequentially into the labeling station. For regular greeting cards with smooth surfaces, the most common method is suction-type sheet separation, which uses negative pressure suction cups to adhere to the top surface of the card, and then lifts or moves the card horizontally to remove it from the stack. However, with the increasing popularity of paper-cut greeting cards with three-dimensional decorative effects, their surface structure and physical properties have fundamentally changed, making traditional suction-type sheet separation methods ineffective, and the automated conveying process faces serious risks of jamming and damage.

[0003] The most distinctive feature of 3D paper-cut greeting cards is that their front or inner pages are created using cutting, folding, and pasting techniques to form three-dimensional shapes protruding from the paper surface, such as flowers, buildings, and figures. When multiple such cards are stacked for transport, the raised parts on each card's surface easily become embedded in the cutout areas, layers, or gaps between adjacent cards, resulting in severe mechanical interlocking, like interlocking components. Simultaneously, to enhance texture and durability, greeting cards are generally treated with high-gloss lamination or coating, resulting in a smooth paper surface. Friction during stacking and handling accumulates a large amount of static charge. In dry environments, the electrostatic attraction is extremely strong, causing the cards to adhere tightly, further increasing the difficulty of separating stacked cards. This combined effect of mechanical interlocking and electrostatic attraction makes the entire stack of cards firmly bound together into a difficult-to-disassemble unit.

[0004] For this type of uneven, interlocking, and electrostatically charged stacked structure, the suction cups of conventional air-suction paging devices cannot establish effective adhesion. Due to the uneven surface of the paper sculpture, the suction cup cannot form a sealed cavity with the card after descending, resulting in a large amount of air leakage from the gaps and insufficient negative pressure to grip the card. Even if the suction cup manages to hold onto a local protrusion, the card below is easily slipped due to the strong interlocking force and electrostatic adsorption, or multiple cards may be pulled up together, causing overlapping failures. Forcibly lifting the card can directly tear or deform the fragile paper sculpture structure, causing irreversible product damage. Therefore, existing air-suction paging and conveying solutions are inadequate for the automatic separation of single, non-destructive, and continuous 3D paper sculpture greeting cards, which severely restricts the efficiency and yield of labeling processing for such products. Therefore, those skilled in the art have proposed a layered conveying device for greeting card labeling and processing to solve the aforementioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a layered conveying device for making and processing greeting cards, which solves the problem that existing air-suction conveying equipment cannot continuously separate individual cards during the conveying process of three-dimensional paper sculpture greeting cards.

A bottom box is provided at the bottom center of the conveying trough seat, and multiple sets of guide rollers and exhaust seats are arranged at equal intervals on the inner bottom of the conveying trough seat.

[0012] Preferably, the guiding and conveying mechanism further includes a fan. The fan is located in the middle of the front side of the bottom box.

Multiple sets of pressure stabilizing and dispersing plates are arranged at equal intervals inside the bottom box. A flow equalization mesh plate is provided on the top inner side of the bottom box. The interior of each exhaust seat is connected to the interior of the bottom box, and the exhaust direction of the exhaust seat is inclined, all facing the end of the conveying trough seat one.

[0013] Preferably, the labeling processing mechanism includes a second conveying trough, which is provided on one side of the middle part of the top of the base. Two sets of laser positioners for positioning the label are equidistantly arranged on the inner wall of the second conveying trough, and an opening is provided at the middle of the inner end of the second conveying trough.

[0014] Preferably, the labeling processing mechanism further includes a moving groove, a moving groove is provided at one side edge of the top of the base, a linear moving module is provided in the moving groove, a hot press seat is provided on the inner top of the linear moving module, a cylinder is provided at the top center of the linear moving module, the rod of the cylinder passes through the linear moving module and is connected to the center of the hot press seat, a negative pressure suction ring seat is provided at the center of the outer wall of the hot press seat, and multiple negative pressure ports are arranged in a circular array at the bottom of the hot press seat.

[0015] Working Principle: When labeling greeting cards, the worker first takes out the cards to be processed from the temporary storage box and neatly stacks them in the stacking box. After the materials are loaded, the output adjustment mechanism is activated. At this time, the stepper driver at the bottom of the base starts to drive the drive seat to rotate. The rotation of the drive seat synchronously drives the inflatable ring belt installed on its outside to run. The inflatable ring belt then drives the fixed actuating needle bar and magnetic sheet to rotate together. During the rotation of the inflatable ring belt, the magnetic sheet on it moves in a cycle. When the magnetic sheet moves, it alternately forms a magnetic repulsion and attraction state with the magnetic seat at the bottom of the lever plate. Under the action of this alternating magnetic force, the magnetic sheet is placed on the inclined slot. The long end of the lever plate inside the stacking box swings back and forth. Simultaneously, the short end of the lever plate moves up and down within the stacking box. During this movement, the bottommost greeting card in the stacking box is gradually released and falls onto the top surface of the base. After the card detaches from the stack, its flat bottom sides fall precisely onto the actuating pins of the inflatable belt, which support it. As the inflatable belt continues to rotate, the actuating pins carry the supported greeting card outwards. At the same time, the lever plate continues its reciprocating motion, discharging the bottommost greeting card from the stacking box, thus completing the adjustment process for the greeting card output. Simultaneously, the card processing mechanism is activated, and the card is fed into the stacking box... During the output adjustment process of the greeting cards, while the cards are still stacked in the storage box, the miniature air pump and miniature humidifier on the inflatable belt are simultaneously activated. The miniature air pump supplies gas to the internal cavity of the inflatable belt to maintain its normal shape during use, while the miniature humidifier humidifies the gas inside the cavity. The humidified gas is then discharged through the exhaust port on the actuating needle, directly acting on the bottom surface of the greeting cards. This humidification effectively reduces static electricity accumulated on the card surface. Furthermore, during the discharge of greeting cards from the bottom of the storage box, the lever plate, through contact with the cards, also helps to reduce static electricity. The partial discharge of static electricity from the surface of the greeting cards can also prevent the greeting cards in the stacking box from being difficult to discharge smoothly and continuously due to static adsorption, thereby further facilitating the subsequent processing of the greeting cards. Afterwards, the greeting cards discharged by the output adjustment mechanism are guided by the rubber arc-shaped guide seat and the central inclined surface on the base and enter the space between the two conveyor rollers in the mounting base. At this time, the drive motor on the mounting base starts, and the drive motor drives the conveyor rollers in the mounting base to rotate synchronously. During the rotation of the conveyor rollers, the rubber edge rings at both ends of the conveyor rollers press and straighten the edges of the greeting cards, while the gap left in the middle of the conveyor rollers can effectively avoid the three-dimensional paper sculpture structure on the surface of the greeting cards and prevent them from being crushed. This completes the processing of the greeting cards after output and before labeling.Next, the guiding conveyor mechanism starts, and the greeting cards, after card processing, are conveyed into conveyor trough one. Inside conveyor trough one, the greeting cards are guided and conveyed by guide rollers. Simultaneously, the fan on the bottom box starts, and the airflow generated by the fan is sent into the bottom box through the connecting box. The airflow entering the bottom box first undergoes buffering, pressure stabilization, and uniform dispersion treatment through multiple sets of pressure-stabilizing and dispersing plates. After multiple buffering, pressure stabilization, and dispersion processes, the airflow is then uniformly distributed through a flow-equalizing perforated plate, and finally smoothly ejected from the exhaust seat. The inclined airflow ejected from the exhaust seat forms a uniform air cushion layer inside conveyor trough one, thereby reducing the friction of the greeting cards during conveying and preventing positional shifts due to friction. When the greeting card is smoothly conveyed to the end of conveyor trough one, it stops moving, completing its guiding and conveying process. At the same time, the labeling processing mechanism starts, and the labels to be affixed to the greeting cards are synchronously conveyed through conveyor trough two. When the labels in conveyor trough two are conveyed to the first... When the laser positioner is in position, the linear motion module in the moving slot is activated and moves to that position. Then, the cylinder rod extends, simultaneously lowering the hot press base at its bottom. Once the hot press base contacts the label in the second conveyor slot, the negative pressure suction ring on the hot press base activates. The negative pressure suction ring generates suction through the negative pressure port at the bottom of the hot press base, firmly adhering the label to its bottom. Next, the linear motion module moves along the moving slot to the position of the second laser positioner in the second conveyor slot. Then, the cylinder rod extends again, simultaneously pulling the hot press base and the label adhering to its bottom through the opening to the desired position on the greeting card in the first conveyor slot. Through heat pressing, the label is precisely affixed to the corresponding position on the greeting card in the first conveyor slot, completing the labeling process. Finally, the labeled greeting card is removed by staff and placed in a collection box for collection, thus completing the labeling process for all greeting cards.

[0016] This invention provides a layered conveying device for producing and processing greeting card labels. It has the following advantages: 1. This invention, by adding and setting an output adjustment mechanism, enables the card labeling and conveying process. On the one hand, the mechanism uses magnetic force to drive the lever plate to swing at high frequency in the inclined slot, flexibly moving the bottom of the stacked cards. This effectively breaks the locking state formed by the interlocking of the three-dimensional paper-cut cards, allowing the cards to be released one by one. On the other hand, the rotating actuating needle only supports the flat edge area of ​​the card, completely avoiding the fragile three-dimensional shape. This not only eliminates the risk of damage to the paper-cut structure, but also realizes the continuous single output of non-flat cards, fundamentally overcoming the problem that the air suction paging cannot establish effective adsorption on undulating surfaces.

[0017] 2. By adding and setting a card processing mechanism, this invention not only uses the humidified gas inside the inflatable ring belt to blow onto the bottom surface of the card through the needle rod exhaust hole during the labeling and conveying process of the greeting card, actively neutralizing and eliminating the static electricity accumulated during the stacking and separation process, but also the contact of the lever plate plays a role in charge conduction, effectively preventing poor separation and accidental re-opening caused by static adsorption. Moreover, the subsequent conveying roller adopts a structure with rubber edge ring pressing to tidy up the edges and a central gap to avoid the paper sculpture, which not only provides the necessary guidance and flatness for the card, but also keeps the three-dimensional parts suspended and free from compression throughout the process, so that the integrity of the paper sculpture shape of the card is fully guaranteed after the static interference is eliminated.

[0018] 3. By adding and setting a guiding conveyor mechanism, this invention utilizes a fan to supply air during the labeling and conveying of greeting cards. Through the fine adjustment of multi-stage pressure-stabilizing and dispersing plates and flow-equalizing perforated plates, a stable and uniform air cushion is formed in the conveying trough. Firstly, the non-contact support method significantly reduces the frictional resistance caused by the unevenness of the paper carving on the bottom surface of the greeting card, allowing it to slide smoothly. Furthermore, the uniform lifting of the air cushion can suppress random deflection and positional movement of the card caused by surface undulations, keeping its posture stable. At the same time, the non-physical contact conveying fundamentally avoids the risk of the paper carving structure being scratched, hooked, or crushed, providing a stable incoming material condition for accurate labeling.

[0019] 4. By adding and setting a labeling processing mechanism, this invention ensures the height accuracy of the material picking and placement points by using two sets of laser positioners to independently calibrate the label and card bonding positions during the labeling process of the greeting card. Furthermore, the negative pressure suction ring seat adsorbs the label from the bottom, which not only avoids the label deformation or damage that may be caused by mechanical clamping, but also conforms to the slight undulations that may exist on the surface of the greeting card, so that the label is firmly and neatly attached after heat pressing. Moreover, the entire process of picking, transferring and bonding cleverly avoids the three-dimensional paper-carved area of ​​the card, thereby completely eliminating the risk of damage to the decorative structure of the greeting card surface while ensuring the labeling quality and positioning accuracy.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 2 This invention provides a layered conveying device for making and processing greeting cards, including a base 1. A temporary storage box 19 for storing greeting cards to be processed and a collection box 20 for collecting finished greeting cards after processing are respectively provided on the rear side of the top of the base 1. A base 2 is fixedly connected to the front middle part of the top of the base 1, and a stacking box 5 for stacking greeting cards to be processed is provided on the top of the base 2. Please see the appendix Figure 3 -Appendix Figure 4 The output adjustment mechanism, which is set on the base 2, is used to continuously output single greeting cards that are stacked vertically in the stacking box 5. The output adjustment mechanism includes a drive seat 8. The drive seats 8 are provided on both the front and rear sides of the base 2. The drive seats 8 on the same side are provided with an inflatable ring belt 3 driven by it. The bottom center of the inner side of the base 2 is provided with a stepper driver 6 that drives the drive seat 8. Multiple actuating pins 4 are provided at equal intervals on the surface of the two adjacent sides of the inflatable ring belts 3.

[0024] When the output adjustment mechanism is started, the stepper driver 6 at the bottom of the base 2 starts to drive the drive seat 8 to rotate. The rotation of the drive seat 8 synchronously drives the inflatable ring belt 3 installed on its outer side to run. The inflatable ring belt 3 then drives the actuating needle rod 4 and the magnetic plate 7 fixed on it to rotate together.

[0025] The output adjustment mechanism also includes a sloping slot 11. Two sloping slots 11 are equally spaced on both sides of the bottom of the stacking box 5. A lever plate 25 is rotatably connected inside the sloping slot 11. The rotating part of the lever plate 25 is located inside the sloping slot 11. The lever plate 25 is divided into a short end and a long end through the rotating part. The short end extends into the stacking box 5 through the sloping slot 11, and the long end extends to the outside through the sloping slot 11. A magnetic seat 27 is provided at the bottom of the long end of the lever plate 25. Multiple magnetic pieces 7 are equally spaced on the outer surface of the inflatable ring belt 3.

[0026] During the rotation of the inflatable ring belt 3, the magnetic sheet 7 on it moves in a cycle. When the magnetic sheet 7 moves, it alternately forms a magnetic repulsion state with the magnetic seat 27 at the bottom of the lever plate 25 and an attraction state with the same poles. Under the action of this alternating magnetic force, the long end of the lever plate 25 placed in the inclined slot 11 swings back and forth. At the same time as the long end of the lever plate 25 swings, its short end also moves back and forth synchronously inside the stacking box 5.

[0027] During this movement, the bottommost greeting card in the stacking box 5 is gradually released and falls onto the top surface of the base 2. After the greeting card is detached from the stack, its flat bottom sides fall precisely onto the actuating pin 4 of the inflatable ring belt 3, which supports it. As the inflatable ring belt 3 continues to rotate, the actuating pin 4 carries the supported greeting card outward. At the same time, the lever plate 25 continues to perform reciprocating motion, discharging the new bottommost greeting card from the stacking box 5, and repeating the cycle for the next card output, thus completing the adjustment process during greeting card output.

[0028] Please see the appendix Figure 5 -Appendix Figure 7 The card processing mechanism, located on one side of the base 2, is used to perform surface treatment on the greeting cards during and after the output process. The card processing mechanism includes a miniature air pump 9. Each of the outer sides of the inflation ring 3 is equipped with a miniature air pump 9 to supply air to its internal cavity. Each of the other outer sides of the inflation ring 3 is equipped with a miniature humidifier 10 to humidify the gas in the internal cavity of the inflation ring 3. Each of the actuating needle rods 4 has multiple exhaust holes 26 that communicate with the internal cavity of the inflation ring 3 at equal intervals.

[0029] When the card processing mechanism is started, while the output adjustment mechanism is adjusting the output of the greeting cards, and before the greeting cards are detached from the stacked state in the stacking box 5, the micro air pump 9 and micro humidifier 10 configured on the inflatable ring belt 3 are started simultaneously. The micro air pump 9 delivers gas to the internal cavity of the inflatable ring belt 3 to maintain the normal shape of the inflatable ring belt 3 during use, while the micro humidifier 10 simultaneously humidifies the gas in the internal cavity of the inflatable ring belt 3.

[0030] The card processing mechanism also includes a mounting base 12. The mounting base 12 is located at the front middle part of the top of the base 1. Two conveying rollers 23 are rotatably connected at equal intervals on the inner middle part of the mounting base 12. Rubber side rings 28 are provided at both ends of the conveying rollers 23. Two drive motors 24 are equidistantly arranged on the front middle part of the mounting base 12, and the output ends of the two drive motors 24 are respectively connected to the middle of one end of the corresponding conveying roller 23.

[0031] Subsequently, the humidified gas inside the inflation ring 3 is discharged through the exhaust hole 26 on the actuating needle bar 4, directly acting on the surface of the bottom of the greeting card. This humidification treatment can effectively reduce the static electricity accumulated on the surface of the greeting card. In addition, during the discharge of greeting cards from the bottom of the stacking box 5, the lever plate 25 can also conduct some of the static electricity from the surface of the greeting card through contact with the greeting card. This can also prevent the greeting cards in the stacking box 5 from being difficult to discharge smoothly and continuously due to static adsorption, thereby further facilitating the subsequent processing of the greeting cards.

[0032] Afterwards, the greeting cards discharged by the output adjustment mechanism are guided by the rubber arc-shaped guide seat and the central inclined surface on the base 2 and enter the space between the two conveyor rollers 23 in the mounting base 12. At this time, the drive motor 24 on the mounting base 12 starts and drives the conveyor rollers 23 in the mounting base 12 to rotate synchronously. During the rotation of the conveyor rollers 23, the rubber edge rings 28 at both ends of the conveyor rollers 23 press and straighten the edges of the greeting cards, while the gap left in the middle of the conveyor rollers 23 can effectively avoid the three-dimensional paper sculpture structure on the surface of the greeting cards and prevent them from being crushed. This completes the processing of the greeting cards after output and before labeling.

[0033] Please see the appendix Figure 8 -Appendix Figure 9 A guiding conveying mechanism is located at the front middle part of the top of the base 1, and is used for conveying greeting cards after they have been processed by the card processing mechanism and for guiding the cards during the conveying process. The guiding and conveying mechanism includes a conveying trough seat 14, which is located on one side of the front part of the top of the base 1. A bottom box 30 is located at the center of the bottom of the conveying trough seat 14. Multiple sets of guide rollers 22 and exhaust seats 29 are arranged at equal intervals on the inner bottom of the conveying trough seat 14. The guiding and conveying mechanism also includes a fan 13, which is located at the center of the front of the bottom box 30. The exhaust port of the fan 13 is connected to the inner bottom of the bottom box 30 through a connecting box. Multiple sets of pressure stabilizing and dispersing plates 32 are arranged at equal intervals inside the bottom box 30. A flow equalization mesh plate 31 is provided on the top of the inner side of the bottom box 30. The interior of each exhaust seat 29 is connected to the interior of the bottom box 30, and the exhaust direction of the exhaust seats 29 is inclined, all facing the end of the conveying trough seat 14.

[0034] When the guiding conveyor is started, the greeting cards after card processing are conveyed into the conveying trough 14. Inside the conveying trough 14, the greeting cards are guided and conveyed by the guide roller 22. At the same time, the fan 13 on the bottom box 30 is started. The airflow generated by the fan 13 is sent into the bottom box 30 through the connecting box. The airflow entering the bottom box 30 is first buffered, stabilized and evenly dispersed by multiple sets of pressure stabilizing and dispersing plates 32. After multiple buffering, stabilizing and dispersing, the airflow is then evenly distributed by the flow equalization mesh plate 31 and finally smoothly sprayed out by the exhaust seat 29.

[0035] The inclined airflow ejected from the exhaust seat 29 forms a uniform air cushion layer inside the conveying trough seat 14, thereby reducing the friction of the greeting card during the conveying process in the conveying trough seat 14 and preventing it from shifting position due to friction. When the greeting card is smoothly conveyed to the end of the conveying trough seat 14, it stops moving, completing the guidance and conveying process.

[0036] Please see the appendix Figure 10 -Appendix Figure 11 The labeling processing mechanism is located on one side of the middle of the top of the base 1 and is used to label the greeting cards conveyed by the guide conveyor mechanism.

[0037] The labeling processing mechanism includes a second conveying trough 16. The second conveying trough 16 is provided on one side of the middle part of the top of the base 1. Two sets of laser positioners 18 for positioning the label are equidistantly arranged on the inner wall of the second conveying trough 16. An opening 34 is provided in the middle of the inner end of the second conveying trough 16.

[0038] When the labeling processing mechanism is started, the labels to be affixed to the greeting card are synchronously conveyed through the second conveyor seat 16. When the labels in the second conveyor seat 16 are conveyed to the position of the first set of laser positioners 18, the linear moving module 15 in the moving slot 21 is started and moves to that position. Then the rod of the cylinder 17 is pushed out. While the rod is pushing out, it drives the hot press seat 33 at its bottom to move down synchronously. After the hot press seat 33 contacts the labels in the second conveyor seat 16, the negative pressure suction ring seat 36 on the hot press seat 33 is started. The negative pressure suction ring seat 36 generates negative pressure suction through the negative pressure port 35 at the bottom of the hot press seat 33, firmly adhering the labels to the bottom of the hot press seat 33.

[0039] The labeling processing mechanism also includes a moving groove 21. A moving groove 21 is provided at one edge of the top of the base 1. A linear moving module 15 is provided inside the moving groove 21. A hot press seat 33 is provided on the top inner side of the linear moving module 15. A cylinder 17 is provided at the middle of the top of the linear moving module 15. The rod of the cylinder 17 passes through the linear moving module 15 and is connected to the middle of the hot press seat 33. A negative pressure suction ring seat 36 is provided in the middle of the outer wall of the hot press seat 33. Multiple negative pressure ports 35 are arranged in a circular array at the bottom of the hot press seat 33.

[0040] Then, the linear motion module 15 moves along the moving groove 21 to the position of the second set of laser positioners 18 in the second conveying trough 16. Then, the rod of the cylinder 17 is pushed out again. At the same time, the rod pushes the hot press seat 33 and the label adsorbed at its bottom through the opening 34 to the position of the greeting card to be affixed in the first conveying trough 14. By hot pressing, the label is accurately affixed to the corresponding position of the greeting card in the first conveying trough 14, completing the labeling process. Finally, the greeting card with the labeling process is taken out by the staff and placed in the collection box 20 for collection, thus completing the labeling process of the greeting card.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
