Description:High-Speed Sheet Attachment System with Independent Roller Control
Field of the Invention
[0001] The present disclosure generally relates to sheet attachment systems. Further, the present disclosure particularly relates to an apparatus for attaching a sheet to a substrate.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In the manufacturing sector, techniques to attach flexible sheets onto rigid or semi-rigid substrates are commonly employed across a wide range of industries, including packaging, electronics, and textiles. Attachment systems for these processes generally involve rollers or other pressing mechanisms to achieve firm and uniform bonding between the sheet and substrate. A challenge frequently encountered involves maintaining a precise alignment of the sheet while ensuring consistent pressure during the attachment. Variations in substrate thickness, surface irregularities, and changes in sheet tension can introduce complications in ensuring the sheet is attached accurately without folds, bubbles, or inconsistencies, which may affect the quality of the finished product.
[0004] Another well-known method involves utilizing fixed-position pressing assemblies that apply uniform pressure over the entire substrate surface. Such a method, however, does not accommodate variations in substrate thickness or irregularities in sheet surface. Consequently, when attachment is performed, the lack of adaptive control often leads to bonding failures or wrinkles. Moreover, in processes where different sheet and substrate combinations are used, fixed-position assemblies prove inefficient and limit operational flexibility. The lack of vertical adaptability in pressing rollers in such systems constitutes a significant drawback, especially when dealing with diverse materials.
[0005] A further method incorporates automated roller systems driven by motor assemblies to ensure continuous movement of sheets over substrates. Such systems often involve high-speed motors synchronizing multiple rollers to support the substrate and press the sheet in a consistent manner. However, commonly known systems lack mechanisms to independently control pressing rollers, which hinders the capacity to adaptively apply varied pressure across sections of the substrate. Such limitations reduce bonding accuracy, especially with substrates exhibiting uneven surfaces or variations in stiffness. Furthermore, the integration of motor-driven rollers without synchronised vertical adjustment of pressing mechanisms restricts adaptability across a range of sheet materials, potentially compromising quality.
[0006] Moreover, while various other techniques incorporate programmable control units to manage motor speeds and roller functions, most do not enable a synchronized approach that combines precise rotational control with real-time adjustment of pressing components. Consequently, challenges remain in achieving a highly controlled, uniform bond across varied material compositions. Additionally, operational inefficiencies arise from the inability to modulate pressure and movement based on substrate properties, which remains a primary limitation in conventional attachment apparatuses.
[0007] In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for attaching sheets to substrates.
[0008] All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.

[0009] Various objects, features, and advantages of the disclosed subject matter can be more fully appreciated with reference to the following detailed description of the disclosed subject matter when considered in connection with the following drawings, in which like reference numerals identify like elements.
[00010] The present disclosure generally relates to sheet attachment systems. Further, the present disclosure particularly relates to an apparatus for attaching a sheet to a substrate.
[00011] In an aspect, the present disclosure provides an apparatus for attaching a sheet to a substrate, comprising a high-speed motor unit controlling a first roller and a second roller, wherein the first roller and the second roller are arranged to support a lower surface of the substrate. A pressing assembly comprising a first pressing roller and a second pressing roller is positioned above the first roller and the second roller, wherein the first pressing roller and the second pressing roller are configured to independently move vertically relative to the substrate. A control unit is coupled to the high-speed motor unit and the pressing assembly, wherein the control unit synchronizes rotational speeds of the first roller and the second roller with vertical movements of the first pressing roller and the second pressing roller for attaching the sheet to the substrate.
[00012] The apparatus includes an alignment feature wherein the first roller aligns tangentially with the first pressing roller, forming a continuous interface that enhances uniform pressure application across the sheet and ensures adherence without displacement during high-speed operations. The apparatus further incorporates a parallel alignment of the second roller with the second pressing roller to facilitate dual-point pressure application across the sheet, providing improved surface contact integrity and preventing warping on the substrate. A staggered configuration is also established by the lateral offset of the first and second rollers, thereby reducing vibration transmission to the substrate and optimizing rolling stability.
[00013] Additionally, the first pressing roller is aligned at an oblique angle relative to the first roller, intersecting to ensure adhesive force consistency across the sheet. A lateral offset between the second pressing roller and the second roller enables precise control of pressure, allowing compensation for surface irregularities on the substrate. A feedback loop monitoring module within the control unit continuously assesses rotational speed of the first and second rollers and adjusts the vertical position of the pressing rollers, enhancing attachment accuracy based on substrate texture. A tension adjustment mechanism is incorporated in the pressing assembly, actively modifying vertical displacement of the pressing rollers to maintain optimal tension between the sheet and substrate during high-speed operation.
[00014] Further, the control unit incorporates an adaptive synchronization algorithm modulating rotational adjustments of the rollers relative to the pressing rollers' vertical positions, which prevents slippage during sheet attachment. The high-speed motor unit includes a torque adjustment feature responsive to load changes on the first and second rollers, coordinated by the control unit to ensure even force application on the sheet during attachment, thereby extending operational lifespan and reducing roller wear.

[00033] FIG. 1 illustrates an apparatus (100) for attaching a sheet 102 to a substrate 104, in accordance with the embodiments of the present disclosure. The apparatus 100 comprises a high-speed motor unit 106 configured to control the operation of a first roller 108 and a second roller 110. The first roller 108 and the second roller 110 are arranged in a manner to support a lower surface of the substrate 104. The high-speed motor unit 106 may incorporate one or more electric motors, preferably capable of providing precise and adjustable rotational speeds suitable for high-speed operations. The motor unit 106 drives both the first roller 108 and the second roller 110 in a coordinated manner, ensuring that the rollers operate at consistent speeds relative to each other to support the substrate 104 uniformly. In one embodiment, the first roller 108 and the second roller 110 may be aligned parallel to each other to create a stable rolling interface that maintains a consistent engagement with the substrate 104. This alignment is particularly useful in high-speed applications where continuous support is necessary to prevent movement or misalignment of the substrate 104 during the sheet attachment process. Additionally, the high-speed motor unit 106 may include torque adjustment features that allow the motor to adapt to load changes, enabling sustained and even force application through the rollers as the sheet 102 is attached to the substrate 104. Such torque adjustment minimizes wear on the rollers and extends the operational lifespan of the apparatus 100, particularly under high-stress conditions that occur during high-speed processing. The motor unit 106 may further include a feedback system that monitors rotational speed and adjusts the force applied by the rollers to accommodate varying thicknesses or textures of the substrate 104, thereby ensuring uniform support and precise handling of the substrate during attachment of the sheet 102.
[00034] The apparatus 100 further includes a pressing assembly 112 comprising a first pressing roller 114 and a second pressing roller 116, which are positioned above the first roller 108 and the second roller 110, respectively. The first pressing roller 114 and the second pressing roller 116 are configured to independently move in a vertical direction relative to the substrate 104, thereby enabling adaptive pressure application on the sheet 102 as it is attached to the substrate 104. This independent vertical movement provides a significant advantage in accommodating substrate surface irregularities, as each pressing roller can adjust its position individually to apply the required pressure without affecting the alignment or stability of the substrate 104. In one embodiment, the first pressing roller 114 and the second pressing roller 116 may be coupled to actuators or servo mechanisms that allow for precise control of their vertical positions. This configuration enables the apparatus 100 to apply consistent and controlled pressure along the sheet 102, even when the substrate 104 has varying thickness or surface inconsistencies. The pressing assembly 112 may further include a mechanism for adjusting the angle or orientation of the pressing rollers to achieve optimal contact with the sheet 102, enhancing the adhesive bond between the sheet 102 and the substrate 104. By allowing the pressing rollers to independently move vertically, the apparatus 100 ensures that the sheet 102 adheres evenly to the substrate 104, which is particularly beneficial for high-speed attachment processes where stability and accuracy are crucial. This arrangement minimizes the risk of wrinkles, bubbles, or other bonding imperfections that can result from inconsistent pressure application, thus ensuring a high-quality attachment of the sheet 102 to the substrate 104.
[00035] The control unit 118 is coupled to the high-speed motor unit 106 and the pressing assembly 112 and is configured to synchronize the rotational speeds of the first roller 108 and the second roller 110 with the vertical movements of the first pressing roller 114 and the second pressing roller 116. This synchronization enables precise coordination between the movement of the support rollers and the pressure applied by the pressing rollers, ensuring that the sheet 102 is accurately and consistently attached to the substrate 104. The control unit 118 may include a programmable logic controller (PLC) or a microprocessor-based control system capable of real-time monitoring and adjustment of the apparatus 100's operating parameters. In one embodiment, the control unit 118 may be equipped with a feedback loop monitoring module that continually assesses the rotational speeds of the rollers and adjusts the vertical movements of the pressing rollers based on variations in the substrate 104's surface texture or thickness. This feedback mechanism enhances the accuracy of the sheet attachment by compensating for any substrate irregularities that may otherwise disrupt the bonding process. Additionally, the control unit 118 may incorporate an adaptive synchronization algorithm that modulates the timing of the rollers' rotational adjustments in relation to the pressing rollers' vertical positioning. This feature prevents slippage of the sheet 102 during attachment, ensuring that the sheet 102 remains stable and properly aligned with the substrate 104 throughout the process. Furthermore, the control unit 118 may allow for pre-set or customizable attachment profiles to accommodate different types of sheets and substrates, providing versatility in application.
[00036] FIG. 2 depicts a flow diagram of an apparatus 100 designed for attaching a sheet 102 to a substrate 104, consistent with embodiments of the present disclosure. The apparatus 100 comprises a high-speed motor unit 106, which is responsible for controlling two rollers: a first roller 108 and a second roller 110. These rollers are arranged to support the lower surface of the

substrate 104, thereby ensuring stability during the attachment process. A pressing assembly 112, positioned above the rollers, includes a first pressing roller 114 and a second pressing roller 116, both of which are capable of independent vertical movement to adaptively apply pressure to the sheet 102. The pressing rollers 114 and 116 operate vertically, enabling precise control over pressure application to accommodate surface irregularities on the substrate 104. A control unit 118 is operatively connected to both the high-speed motor unit 106 and the pressing assembly 112. This control unit 118 synchronizes the rotational speeds of the support rollers with the vertical displacement of the pressing rollers, ensuring consistent and accurate attachment of the sheet 102 to the substrate 104. This coordinated system enhances bonding precision, especially during high-speed operations.
[00037] In an embodiment, the apparatus 100 incorporates a first roller 108 positioned to align tangentially with a first pressing roller 114, forming a continuous rolling interface that facilitates uniform application of pressure along the entire length of the sheet 102. This tangential alignment allows the first roller 108 and the first pressing roller 114 to maintain consistent contact with both the substrate 104 and the sheet 102, ensuring that pressure is applied evenly. As a result, the sheet 102 adheres uniformly to the substrate 104, which prevents issues such as wrinkling, displacement, or misalignment, particularly during high-speed operations. The continuous rolling interface created by the alignment of the first roller 108 with the first pressing roller 114 further enhances bonding consistency by minimizing any variation in pressure distribution. This feature is particularly beneficial in applications where the sheet 102 needs to be attached to the substrate 104 with high precision and consistency, even under rapid processing conditions, thereby promoting stable and high-quality bonding.
[00038] In an embodiment, the apparatus 100 features a second roller 110 positioned in parallel alignment with a second pressing roller 116, enabling a dual-point pressure application across the sheet 102 as it is attached to the substrate 104. The parallel alignment between the second roller 110 and the second pressing roller 116 ensures that the sheet 102 receives even pressure distribution on both sides, reducing the likelihood of warping or misalignment. This dual-point pressure application is essential for achieving a smooth and uniform bond between the sheet 102 and the substrate 104, especially in scenarios involving substrates with variable thickness or rigidity. By maintaining pressure evenly across the sheet 102, the apparatus 100 improves the surface contact integrity between the sheet 102 and the substrate 104, resulting in a more reliable and stable attachment. Such an arrangement is highly advantageous for high-speed applications, as it provides a balanced pressure distribution that enhances the durability and quality of the attachment process.
[00039] In an embodiment, the apparatus 100 comprises a first roller 108 positioned with a direct lateral offset from a second roller 110, creating a staggered configuration that serves to minimize vibrations transmitted to the substrate 104 during the sheet attachment process. The lateral offset arrangement between the first roller 108 and the second roller 110 ensures that any vibrations generated during high-speed roller operation are distributed more evenly, thereby preventing the substrate 104 from experiencing concentrated stress points. This configuration optimizes the stability of the rolling interface, which is essential in maintaining consistent contact between the sheet 102 and the substrate 104 throughout the attachment process. Additionally, the staggered alignment between the first and second rollers improves the apparatus 100's ability to handle substrates with varying degrees of stiffness or flexibility, as it mitigates the risk of displacement or misalignment caused by roller-induced vibrations. As a result, the staggered roller arrangement enhances the overall stability and reliability of the sheet attachment process.
[00040] In an embodiment, the apparatus 100 includes a first pressing roller 114 that is rotatably coupled above the first roller 108 at an oblique angle, forming an intersecting alignment that increases the consistency of adhesive force across the sheet 102 as it is attached to the substrate 104. The oblique angle of the first pressing roller 114 relative to the first roller 108 enables controlled variations in pressure application across different sections of the sheet 102, enhancing its adherence to the substrate 104, particularly in high-speed applications where uniform pressure is essential. This intersecting alignment helps to improve the adhesive force distribution, ensuring that the sheet 102 remains stable and properly aligned with the substrate 104 throughout the attachment process. The oblique configuration is particularly advantageous in applications where substrates have surface irregularities or varying material properties, as it provides an adaptive pressure mechanism that accommodates these variations, promoting a consistent and high-quality bond between the sheet 102 and the substrate 104.
[00041] In an embodiment, the apparatus 100 incorporates a second pressing roller 116 positioned laterally offset relative to the second roller 110, allowing for fine control over the pressing pressure applied to the sheet 102 during its attachment to the substrate 104. The lateral offset of the second pressing roller 116 in relation to the second roller 110 enables the apparatus 100 to dynamically adjust pressure in response to any surface irregularities present on the substrate 104, thereby preventing potential bonding issues such as uneven adhesion or slippage. This configuration is particularly beneficial in scenarios where substrates vary in thickness or texture, as it facilitates a more adaptive pressure application that compensates for these irregularities. The precise control provided by the lateral offset positioning of the second pressing roller 116 enhances the accuracy of the sheet attachment process, resulting in a stable and consistent bond between the sheet 102 and the substrate 104, even under high-speed operational conditions.
[00042] In an embodiment, the apparatus 100 is equipped with a control unit 118 that includes a feedback loop monitoring module configured to continually assess the rotational speeds of the first roller 108 and the second roller 110, as well as the vertical movement of the first pressing roller 114 and the second pressing roller 116. The feedback loop monitoring module enables the apparatus 100 to dynamically adjust the roller speeds and pressing roller positions based on real-time variations in the surface texture or thickness of the substrate 104. By continually monitoring and adjusting these parameters, the control unit 118 ensures that the sheet 102 is accurately and consistently attached to the substrate 104, regardless of substrate irregularities. This continuous feedback mechanism enhances the precision of the attachment process, reducing the likelihood of bonding defects such as misalignment or uneven pressure application. The feedback loop monitoring module is particularly advantageous in high-speed attachment applications, as it allows the apparatus 100 to maintain stable and uniform bonding quality even under rapid operational conditions.
[00043] In an embodiment, the pressing assembly 112 within the apparatus 100 incorporates a tension adjustment mechanism designed to actively modify the vertical displacement of the first pressing roller 114 and the second pressing roller 116 in response to feedback signals from the control unit 118. This tension adjustment mechanism allows the pressing assembly 112 to maintain optimal tension between the sheet 102 and the substrate 104 during high-speed operations, ensuring that the sheet 102 adheres securely to the substrate 104 without excess slack or tension. The active adjustment of vertical displacement provided by the tension mechanism is particularly beneficial in applications where substrate characteristics such as thickness and rigidity vary, as it enables the apparatus 100 to adapt its pressure application in real time. This tension adjustment feature helps to prevent issues such as wrinkling or displacement of the sheet 102, resulting in a stable and high-quality attachment process that meets the demands of high-speed industrial operations.
[00044] In an embodiment, the control unit 118 within the apparatus 100 includes an adaptive synchronization algorithm that modulates the timing of rotational adjustments of the first roller 108 and the second roller 110 relative to the vertical positioning of the first pressing roller 114 and the second pressing roller 116. The adaptive synchronization algorithm is designed to prevent slippage of the sheet 102 during attachment by coordinating the rollers' rotational movements with the pressing rollers' vertical adjustments. This feature is particularly advantageous in high-speed operations, where precise timing is crucial to maintaining alignment and stability of the sheet 102 as it is attached to the substrate 104. By modulating the timing of these movements, the adaptive synchronization algorithm enhances the apparatus 100's ability to securely and accurately bond the sheet 102 to the substrate 104, reducing the risk of misalignment or pressure inconsistencies that could compromise the quality of the attachment.
[00045] In an embodiment, the high-speed motor unit 106 within the apparatus 100 incorporates a torque adjustment feature that is responsive to load changes experienced by the first roller 108 and the second roller 110. This torque adjustment feature is coordinated by the control unit 118, which ensures sustained and even force application on the sheet 102 as it is attached to the substrate 104. By adapting the motor unit 106's torque in response to variations in load, the apparatus 100 maintains consistent pressure on the sheet 102, preventing issues such as roller slippage or uneven force distribution. This torque adjustment feature is particularly useful in high-speed applications where rapid load fluctuations can occur due to changes in substrate or sheet characteristics. By providing stable force application, the torque adjustment feature reduces wear on the rollers and extends the operational lifespan of the apparatus 100, enhancing the overall efficiency and durability of the sheet attachment process.
