Description

Technical Field

[0001] This invention relates to the technical field of paper cross-page mounting mechanisms, specifically to a thin paper cross-page mounting mechanism and its mounting method. Background Technology

[0002] Butterfly binding laminating machines are commonly used in album production, but they only support paper weights of 180gsm and above, relying on the paper's stiffness to resist mechanical stress. Currently, most commercially available brochures use thinner paper, typically 128gsm, and employ perfect or saddle stitching, resulting in broken images across pages and the inability to lay flat at 180°, affecting visual presentation. High-end brochures and art publications urgently require butterfly binding to enhance their quality, but 128gsm paper lacks sufficient stiffness, making traditional equipment unsuitable. To meet the needs of commercially available brochures (typically 128gsm paper), this paper proposes a fully automatic butterfly binding laminating machine and its control method suitable for thin paper (128gsm). The core workflow of mainstream fully automatic butterfly binding laminating machines typically includes: paper feeding, gluing, alignment (collision alignment), bonding and pressing, collection into a booklet, and booklet output. When handling thin paper, the key technical implementation schemes and disadvantages are as follows:

[0003] (1) Alignment process: The “collision alignment” method is adopted. After the paper is coated with glue, it is sent to a fixed guide or baffle by the conveying mechanism. The paper edge is made to collide with the guide by the inertia of the paper or a slight mechanical force, and the spine edge is aligned by the collision.

[0004] Disadvantages: Insufficient rebound, unable to align properly. For thin paper such as 128g, its stiffness and resilience are severely lacking. After a collision, the paper cannot rebound effectively and adhere tightly to the guide rail like thicker paper, resulting in the spine edge being loose and skewed, making precise alignment impossible.

[0005] (2) Adhesion and smoothing stage: After the paper is aligned, it is usually adhered and initially smoothed by pressing down in the vertical direction (perpendicular to the paper surface) using a simple pressure plate or roller. Alternatively, it can be adhered by the weight of the paper itself and the pressure of subsequent collection.

[0006] Disadvantages: Insufficient smoothing, prone to bulging; vertical pressing is not effective in completely and evenly expelling air between the two thin sheets of paper, especially from the spine outwards. The thin paper itself lacks stiffness, making it more prone to wrinkles or localized bulges during pressing, forming a "bulge" defect.

[0007] (3) Bookbinding and pushing stage: Use a fixed or movable baffle (pushing plate) to push the bound book from the spine or side to push it out or transfer it to the next station.

[0008] Disadvantages: Failure to push the book; poor overall rigidity of thin books; even slight uneven force from the pusher or slight tilting of the book can easily cause the book to bend, fold, or get stuck, making it impossible to push out smoothly. The rigid contact between the pusher and the thin book can easily cause creases, indentations, or even tears on the spine or cover edges, damaging the finished product. Therefore, a thin paper flat-laying and mounting mechanism is provided to solve the above problems. Summary of the Invention

[0009] To address the problems mentioned in the background section, the technical solution adopted by this invention is: a thin paper laminating mechanism, which can be used for laminating 128g thin paper across multiple pages, comprising: a suction conveyor platform and a mechanical gripping wheel assembly disposed at the output end of the suction conveyor platform. A laminating platform is disposed on one side below the mechanical gripping wheel assembly. Both the suction conveyor platform and the mechanical gripping wheel assembly disposed at the output end of the suction conveyor platform are installed inside the machine body. The suction conveyor platform includes a suction belt, a suction pipe inlet, and a power transmission line. The machine includes a conveyor motor output drive connected to a suction belt, and a suction pipe inlet connected to the inner side of the suction belt. The mechanical gripper assembly includes a mounting and pressing mechanism and a gripper mechanism. The mounting and pressing mechanism includes a rotating rod, a synchronous pulley, and a red-adhesive synchronous belt. One end of the rotating rod is connected to the output end of the mechanical gripper motor. The synchronous pulley is connected to the outside of the rotating rod through a bearing. The red-adhesive synchronous belt is wound around the outside of the synchronous pulley. The gripper mechanism is a driven rolling mounting structure that drives the mounting and pressing mechanism to loosely and tightly adhere the paper on the mounting platform 6. The machine also includes a fixed block, a movable rod, a spring, a movable plate, a cam, a movable clamp, a fixed clamp, a lower sheet metal, and an upper sheet metal. The fixed block is keyed to the outside of the rotating rod. The movable rod slides through the inside of the fixed block. The spring is sleeved on one end of the movable rod. The movable plate is fixedly connected to the movable rod at one end of the spring. The cam is fixedly connected to one side of the movable clamp. The fixed clamp is fixedly connected to one side of the fixed block. The lower and upper sheet metal are fixedly connected inside the machine body.

[0010] As a preferred embodiment of the present invention, the movable clamp is fixedly connected to one side of the movable plate, and the movable clamp is directly opposite the fixed clamp.

[0011] As a preferred embodiment of the present invention, a rolling assembly is installed on one side of the inside of the machine body, and an adhesive application assembly is installed on the side of the output end of the rolling assembly inside the machine body.

[0012] As a preferred embodiment of the present invention, the glue application assembly includes a glue application frame, a thin cylinder, an upper glue application shaft, a water glue outlet, and a lower glue application shaft. The thin cylinder, the upper glue application shaft, the water glue outlet, and the lower glue application shaft are all mounted on the glue application frame, which is fixedly installed inside the machine body.

[0013] As a preferred technical solution of the present invention, the mounting platform includes a PU flat belt, a spine baffle, a spring, an alignment fork, a photo paper position cylinder, a fork lifting cylinder, and a layer position cylinder. A spine baffle is provided on one side of the PU flat belt, the spring is provided at the top of the spine baffle located on one side of the PU flat belt, and the alignment fork is located above the spine baffle.

[0014] As a preferred embodiment of the present invention, the photo paper position cylinder, the fork lifting cylinder, and the interlayer position cylinder are fixedly installed on one side of the mounting platform, and one side of the PU flat belt is connected to the output end of the book output motor.

[0015] As a preferred embodiment of the present invention, a mounting platform lifting motor is installed at the bottom of the mounting platform, and the output end of the lifting motor is connected to a ball screw.

[0016] As a preferred embodiment of the present invention, a suction fan is installed at the bottom of the machine body, and the suction end of the suction fan is connected to the suction pipe inlet through a pipe.

[0017] As a preferred embodiment of the present invention, a guide rail is provided inside the machine body below the mounting platform, the mounting platform is connected to the guide rail, and a reciprocating motor for the mounting table is installed inside the machine body. The reciprocating motor for the mounting table drives the mounting platform and the synchronous pulley.

[0018] A mounting method based on the above-mentioned thin paper flat mounting mechanism, characterized by comprising the following:

[0019] S1. Under the action of the suction fan, the adhesive paper is conveyed forward along the suction belt and reaches the position of the mechanical gripper wheel;

[0020] S2. When the mounting photoelectric sensor detects that the photographic paper has reached the precise position, it triggers the clamping action. The clamping mechanism of the photographic paper is driven by the synchronous belt pulley of the mechanical claw motor, and moves along the lower sheet metal curve to the upper sheet metal position in conjunction with the cam. At the same time, the cam is squeezed by the sheet metal, which causes the spring to switch from the relaxed state, driving the clamping claw to close and clamp the photographic paper.

[0021] S3. After the photographic paper is gripped, the synchronous pulley drives the entire assembly to rotate counterclockwise. During this process, the gripper mechanism remains taut.

[0022] When the cam moves to the lower sheet metal position again, it is squeezed by the sheet metal again, the spring returns to a relaxed state, and the gripper mechanism releases.

[0023] At the same time, the spring clips press down on the loosened photographic paper and prevent it from springing back through physical fixation, ensuring that the mounting is neat.

[0024] It also includes the following:

[0025] S4. After the mounting is neat, roll it using the rolling assembly to ensure the spine is pressed firmly.

[0026] S5. The gluing component involves applying glue to the top of the folded photographic paper but not to the bottom.

[0027] S6. The mounting platform achieves precise alignment and bonding of two sheets of glued photographic paper.

[0028] The present invention has the following advantages: it sets up a cooperating structure of mechanical gripping wheel assembly to realize a mechanical gripping wheel rotation mechanism that grips, precisely positions, and releases without rebound, ensuring that even 128-gram thin paper can have its spine edge precisely clamped and placed in the target alignment position, and is immediately fixed by an auxiliary mechanism (spring clip) after release to eliminate the effect of rebound;

[0029] After the glued paper is gripped by the gripping wheel claws, it moves along the curved surface of the gripping wheel. When it touches the bottom structure of the gripping wheel, the gripping wheel releases the paper under the action of the spring. At this time, the mounting platform moves upward and to the right along with the belt. Under the pressure of the belt and the mounting platform, it ensures that the two thin papers are fully compressed at the moment of bonding, and the air is effectively expelled, thus fundamentally solving the bulging problem.

[0030] Furthermore, it employs a mechanism that uses belt drive to smoothly "transmit" or "carry out" the bound books by following the movement of the mounting platform itself, thus avoiding the application of concentrated rigid thrust to the book body and ensuring that the book remains intact, flat, and undamaged during the output process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The invention will now be further described with reference to the accompanying drawings.

[0048] Please refer to the following: Figures 1-13 This invention discloses a thin paper lamination and mounting mechanism, which can be used for lamination and mounting of 128g thin paper across multiple pages. It includes: a suction conveyor platform 4 and a mechanical gripper wheel assembly 5 disposed at the output end of the suction conveyor platform 4. A mounting platform 6 is disposed on one side below the mechanical gripper wheel assembly 5. Both the suction conveyor platform 4 and the mechanical gripper wheel assembly 5 disposed at the output end of the suction conveyor platform 4 are installed inside the machine body 1. The suction conveyor platform 4 includes a suction belt 401, a suction pipe inlet 402, and a conveyor motor 403. The output drive of the conveyor motor 403 is connected to the suction belt 401. The suction pipe inlet 402 is connected to the inner side of the suction belt 401. The mechanical gripper wheel assembly 5 includes a mounting pressing mechanism and a gripper mechanism. The mounting pressing mechanism includes a rotating rod 501, a synchronous pulley 502, and a red-adhesive synchronous belt 503. One end of the rotating rod 501 is connected to the output end of the mechanical gripper motor. The synchronous pulley 502 is connected via a bearing. Connected to the outside of the rotating rod 501, a red adhesive synchronous belt 503 is wrapped around the outside of the synchronous belt pulley 502. The gripper mechanism is a drive rolling mounting structure that drives the mounting pressing mechanism to loosely and tightly adhere the paper on the mounting platform 6. As shown in the figure, it includes a fixed block 504, a movable rod 505, a spring 506, a movable plate 507, a cam 508, a movable chuck 509, a fixed chuck 510, a lower sheet metal 512, and an upper sheet metal 513. The fixed block 504 is keyed to the outside of the rotating rod 501. The movable rod 505 slides through the inside of the fixed block 504. The spring 506 is sleeved on one end of the movable rod 505. The movable plate 507 is fixedly connected to the movable rod 505 at one end of the spring 506. The cam 508 is fixedly connected to one side of the movable chuck 509. The fixed chuck 510 is fixedly connected to one side of the fixed block 504. The lower sheet metal 512 and the upper sheet metal 513 are fixedly connected to the inside of the machine body 1.

[0049] Combination Figure 2 and Figure 5As shown, the suction conveying platform 4 conveys the glued photographic paper to the mechanical gripper assembly 5. The conveying motor 403 drives the suction belt 401 to move forward. The suction fan 7 is connected to the suction pipe inlet 402 through the air duct to perform suction. The suction belt 401 is a perforated device. Under the action of the suction fan 7, the glued paper is conveyed forward along the suction belt 401 to the mechanical gripper position.

[0050] The glued photographic paper is conveyed by the suction conveyor platform 4. When the mounting photoelectric sensor detects that the photographic paper has reached the precise position, it triggers the gripping action. The gripper mechanism for gripping photographic paper is driven by the synchronous pulley 502 of the mechanical gripper motor, and moves along the curve of the sheet metal (lower sheet metal 512 and upper sheet metal 513) to the position of the upper sheet metal 513 in conjunction with the cam 508.

[0051] At this time, cam 508 is compressed by the sheet metal, causing spring 506 to switch from a relaxed state, driving the gripper to close and clamp the photographic paper. That is, the eccentric cam combined with the spring reset setting ensures that the sheet metal guide trajectory is such that when cam 508 is in contact with the upper sheet metal, the spring is compressed; when cam 508 is in contact with the lower sheet metal, the spring is relaxed. Whether cam 508 remains in contact with the sheet metal throughout its rotation is crucial. Figure 6 As shown, the lower sheet metal 512 and the upper sheet metal 513 are combined to form a semi-circle.

[0052] Photo paper feeding process: After the photo paper is gripped, the synchronous pulley 502 drives the entire assembly to rotate counterclockwise. During this process, the gripper mechanism remains taut to ensure that the grippers continuously hold the photo paper and prevent it from falling off. The gripper wheel drive is equipped with a separate motor, which is separate from the reciprocating motor of the mounting table.

[0053] Photo paper release and fixation: When the cam 508 moves to the position of the lower sheet metal 512, it is squeezed by the sheet metal again, the spring 506 returns to a relaxed state, and the gripper mechanism is released;

[0054] At the same time, the spring clip 603 presses down on the loosened photographic paper, physically fixing it to prevent it from springing back and ensuring neat mounting.

[0055] The movable clamp 509 is fixedly connected to one side of the movable plate 507, and the movable clamp 509 faces the fixed clamp 510. A rolling assembly 2 is installed on one side of the machine body 1. An adhesive applicator 3 is installed inside the machine body 1 on the output side of the rolling assembly 2. The adhesive applicator 3 includes an adhesive applicator frame 301, a thin cylinder 302, an upper adhesive applicator shaft 303, a water adhesive outlet 304, and a lower adhesive applicator shaft 305. The thin cylinder 302, upper adhesive applicator shaft 303, water adhesive outlet 304, and lower adhesive applicator shaft 305 are all mounted on the adhesive applicator frame 301, which is fixedly installed inside the machine body 1. The rolling assembly 2 uses five rollers 203 to roll and press, ensuring the spine of the book is firmly pressed.

[0056] The adhesive applicator 3 applies adhesive to the top of the folded photographic paper, leaving the bottom uncoated. Under external force, the adhesive flows from the adhesive outlet 304 to the upper adhesive shaft 303, which continuously rotates, evenly distributing the adhesive across its surface. The first photo in the album is uncoated. The thin cylinder 302 controls the up-and-down movement of the lower adhesive shaft 305. When the first photo is in the album, the thin cylinder 302 remains in a relaxed state, preventing the photographic paper from contacting the upper adhesive shaft 303 and ensuring the first photo is uncoated. When the second photo passes by, the lower adhesive shaft 305 moves upward under the action of the thin cylinder 302, causing the top surface of the photographic paper to come into contact with the upper adhesive shaft 303 and be fully coated with adhesive.

[0057] The mounting platform 6 includes a PU flat belt 601, a spine baffle 602, a spring 603, an alignment fork 604, a photo paper position cylinder 605, a fork lifting cylinder 606, and a layering position cylinder 607. The spine baffle 602 is provided on one side of the PU flat belt 601. The spring 603 is located at the top of the spine baffle 602 on one side of the PU flat belt 601. The alignment fork 604 is located above the spine baffle 602. The photo paper position cylinder 605, the fork lifting cylinder 606, and the layering position cylinder 607 are fixedly installed on one side of the mounting platform 6. One side of the PU flat belt 601 is connected to the output end of the book output motor 608. A mounting platform lifting motor is installed at the bottom of the mounting platform 6, and the output end of the lifting motor is connected to a ball screw. A suction fan 7 is installed at the bottom of the machine body 1. The suction end of the suction fan 7 is connected to the suction pipe inlet 402 through a pipe. A guide rail 8 is set inside the machine body 1 below the mounting platform 6. The mounting platform 6 is connected to the guide rail 8. A reciprocating motion motor 9 for the mounting table is installed inside the machine body 1. The reciprocating motion motor 9 drives the mounting platform 6.

[0058] The mounting platform 6 achieves precise alignment and bonding of two sheets of glued photographic paper. Its specific workflow is as follows:

[0059] When the glued photographic paper reaches the designated position under the rolling conveyor of the mechanical claw wheel, the alignment fork 604 is in a ready state (at this time, the front baffle of the alignment fork 604 is flush with the front baffle of the spine baffle 602, and the lower baffle of the alignment fork 604 is extended). Under the action of the conveying force, the photographic paper collides with the front baffle of the alignment fork 604, and then the three springs 603 generate a downward force to press the photographic paper firmly. During this process, the photographic paper position cylinder 605 retracts, causing the lower baffle of the alignment fork 604 to retract to the right. Immediately afterwards, the three springs 603 continue to maintain downward pressure, so that the photographic paper is aligned along the spine baffle 602 and placed downward. Afterward, the alignment fork 604 lifting cylinder pushes upward, and after a delay, the photographic paper position cylinder 605 extends to the left, and after a delay, the fork lifting cylinder 606 falls downward. The alignment fork 604 returns to its initial state, waiting to receive the next photographic paper.

[0060] Simultaneously, the mounting platform 6, driven by the mounting platform lifting motor, is pushed upwards using a ball screw. When the platform rises to the preset position, the upper limit photoelectric sensor of the mounting platform detects the position signal in real time and transmits it to the PLC control system, which then precisely controls the platform to stop. Subsequently, under the action of the mounting platform reciprocating motor 9, the platform presses against the photographic paper and moves to the right. At the same time, the photographic paper is held down by the red glue synchronous belt 503 above and pushed upwards by the PU flat belt 601 of the mounting platform 6 below, with both maintaining synchronous contact and movement. Through this coordinated action, the two sheets of glued photographic paper can be fully compacted and air bubbles can be squeezed outwards from the spine, effectively solving the "bulging" defect that easily occurs in the mounting process of traditional equipment.

[0061] If an additional layer is needed to increase the thickness of the photographic paper, the layer mounting cylinder 607 and the photographic paper mounting cylinder 605 will operate simultaneously (in an extended state) during the mounting process. At this time, the front baffle of the alignment fork 604 will extend a certain distance beyond the front baffle of the spine baffle 602. This extension distance can be adjusted within the range of 0-5mm according to actual needs. This setting enables precise alignment of the layers, and it can be observed that there is a certain distance between the layer and the spine. The purpose is to create a misalignment between the layer and the spine of the photographic paper, thereby leaving a gap and preventing the two layers from "touching back" when laid flat, thus achieving a 180° opening for the butterfly binding.

[0062] The above working principle is also a mounting method based on the aforementioned thin paper flat mounting mechanism, namely:

[0063] S1. Under the action of the suction fan 7, the adhesive paper is conveyed forward along the suction belt 401 and reaches the mechanical gripper.

[0064] S2. When the mounting photoelectric sensor detects that the photographic paper has reached the precise position, it triggers the clamping action. The clamping mechanism for the photographic paper is driven by the synchronous pulley 502 of the mechanical claw motor, and moves along the curve of the lower sheet metal 512 to the position of the upper sheet metal 513 with the cam 508. At the same time, the cam 508 is squeezed by the sheet metal, which causes the spring 506 to switch from the relaxed state, drive the clamping claw to close, and clamp the photographic paper.

[0065] S3. After the photographic paper is gripped, the synchronous pulley 502 drives the entire assembly to rotate counterclockwise. During this process, the gripper mechanism remains taut.

[0066] When the cam 508 moves to the lower sheet metal 512 position again, it is squeezed by the sheet metal again, the spring 506 returns to a relaxed state, and the gripper mechanism is released.

[0067] At the same time, the spring clip 603 presses down on the loosened photographic paper and prevents it from springing back through physical fixation, ensuring neat mounting;

[0068] S4. After the mounting is neat, roll it using the rolling assembly 2 to ensure the spine is pressed firmly.

[0069] S5, the glue-applying component 3 applies glue to the top of the folded photographic paper but not to the bottom;

[0070] S6, mounting platform 6 enables precise alignment and bonding of two glued photographic papers.

[0071] The above structure and principle can be fully implemented:

[0072] A mechanical gripping wheel assembly is designed to achieve an active gripping, precise positioning, and rebound-free release mechanism. This ensures that even 128g thin paper can have its spine edge precisely gripped and placed in the target alignment position, and is immediately fixed by an auxiliary mechanism (spring clip) after release, eliminating the impact of rebound.

[0073] After the glued paper is gripped by the gripping wheel claws, it moves along the curved surface of the gripping wheel. When it touches the bottom structure of the gripping wheel, the gripping wheel releases the paper under the action of the spring. At this time, the mounting platform moves upward and to the right along with the belt. Under the pressure of the belt and the mounting platform, it ensures that the two thin papers are fully compressed at the moment of bonding, and the air is effectively expelled, thus fundamentally solving the bulging problem.

[0074] Furthermore, it employs a mechanism that uses belt drive to smoothly "transmit" or "carry out" the bound books by following the movement of the mounting platform itself, thus avoiding the application of concentrated rigid thrust to the book body and ensuring that the book remains intact, flat, and undamaged during the output process.

[0075] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

[0076] Other parts of this invention that are not detailed herein are all prior art and will not be described further here.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

Under the action of the suction fan, the adhesive paper is conveyed forward along the suction belt and reaches the position of the mechanical gripper wheel; S2. When the mounting photoelectric sensor detects that the photographic paper has reached the precise position, it triggers the clamping action. The clamping mechanism of the photographic paper is driven by the synchronous belt pulley of the mechanical claw motor, and moves along the lower sheet metal curve to the upper sheet metal position in conjunction with the cam. At the same time, the cam is squeezed by the sheet metal, which causes the spring to switch from the relaxed state, driving the clamping claw to close and clamp the photographic paper. S3. After the photographic paper is gripped, the synchronous pulley drives the entire assembly to rotate counterclockwise. During this process, the gripper mechanism remains taut. When the cam moves to the lower sheet metal position again, it is squeezed by the sheet metal again, the spring returns to a relaxed state, and the gripper mechanism is released; At the same time, the spring clips press down on the loosened photographic paper and prevent it from springing back through physical fixation, ensuring that the mounting is neat.
