Description

Technical Field

[0001] This invention relates to the field of paper deacidification technology, and more specifically, to an intelligent operating system and deacidification method for paper deacidification equipment. Background Technology

[0002] Paper is the primary medium for ancient books, paintings, calligraphy, archives, and other materials, possessing multiple values ​​including historical significance, collection value, and research value. Acidification of paper causes the degradation of its main components—cellulose, hemicellulose, and lignin—leading to a decrease in polymerization degree, weakened paper strength, and even flocculation. Currently, deacidification equipment produced in my country is mainly handheld and stationary types. Their working principle involves spraying deacidifying solution onto the paper surface under pressure. For handheld equipment, due to manual handling, it is often affected by human factors, making it difficult to accurately control the amount and uniformity of the deacidifying solution sprayed onto the paper, easily causing uneven deacidification; at the same time, manual operation also suffers from low efficiency. For stationary deacidification equipment, the working principle is that the paper to be treated is fixed on the deacidification operating table by manual operation, and the deacidifying solution is sprayed onto the paper surface using a spray device. After the deacidification process is completed, the paper is manually removed and either left in place or transferred to another location for drying. The problems include: In scenarios using aqueous deacidification solutions, the increased moisture content of the paper after spraying can easily cause deformation or breakage during paper removal or transfer, especially for paper with low wet strength. Secondly, during the natural drying process after aqueous deacidification, the uneven evaporation rate of moisture can cause the paper to curl after drying, making it difficult to ensure the flatness of the deacidified paper. Currently, deacidification equipment in my country is mainly single-module, with separate operations for paper preparation, deacidification, and drying. 1) In the paper preparation module, sheets of paper to be deacidified need to be manually laid flat on the deacidification panel. After deacidification, the paper is removed and transferred for drying, requiring many operators and resulting in low efficiency. 2) In the deacidification module, mist spraying devices are often used to spray the deacidification solution onto the paper surface. For handheld deacidification equipment, it is difficult to quantitatively measure the sprayed solution and control the amount of liquid sprayed onto the paper surface, leading to uneven dispersion of the deacidification solution on the paper surface. Furthermore, current deacidification panels mostly use belt conveyors, requiring the deacidified paper to be removed from the conveyor belt promptly, resulting in low efficiency. However, for deacidification equipment using aqueous deacidification solutions, the increased moisture content and decreased wet strength of the paper after deacidification easily lead to breakage and deformation during transfer, causing secondary damage. 3) In the drying module, currently, deacidified paper is mostly dried by natural air drying, vacuum drying, or forced-air drying ovens. Natural air drying, in particular, easily causes paper curling and other deformation problems. 4) Moreover, the current separate operation of paper preparation, deacidification, and drying modules requires significant manpower and is inefficient, making it difficult to achieve efficient batch operations.

[0039] According to another embodiment of the present invention, the working principle and workflow of the intelligent operating system of the paper deacidification equipment of any of the above embodiments are also disclosed:

[0040] This invention mainly includes: a paper preparation table (paper preparation unit), a paper deacidification operating table (deacidification unit), a paper drying table (drying unit), and a conveying robotic arm (conveying unit); the main function of the paper preparation table is: the robotic arm picks up one sheet of paper placed on the single-sheet paper carrier and places it on the paper tray at a time. Each paper tray can hold three sheets of paper. This module includes a pretreatment table support, paper trays, and a single-sheet paper carrier. The paper trays have three grooves that can hold three sheets of paper at the same time; the main function of the paper deacidification operating table is: the deacidification mechanism deacidifies the single sheets of paper placed on the paper trays. This module includes a paper deacidification support, paper trays, a heating and stirring tank, a quantitative constant pressure module, an XY plane motion module, a quantitative spraying device, a vacuum adsorption table, a vacuum pump, and related pipelines; the main function of the paper drying table is: to dry the deacidified paper. This module includes a drying support, a heating water tank, a water pump, a water bath heating table, and a temperature sensor, etc.

[0041] The detailed workflow includes:

[0042] I. Paper Preparation:

[0043] The paper preparation table contains paper trays and unprocessed paper. The unprocessed paper is stacked individually. The robotic arm uses suction cups on its multi-functional robotic arm at the front end to pick up individual sheets of paper and lays them flat in the grooves on the paper tray. The paper tray has three grooves. The robotic arm places the picked-up paper into the three grooves on the paper tray in sequence. This design enables efficient paper preparation.

[0044] II. Deacidification treatment:

[0045] The robotic arm uses a special gripper on the paper tray on its multi-functional robotic arm at the front end to lift and lock the paper tray on the paper pretreatment table and place it in the correct position on the paper deacidification table. Then the robotic arm releases the special gripper on the paper tray on its multi-functional robotic arm at the front end, thereby releasing the paper tray. This design enables the paper to be processed and the paper tray to be transferred to the deacidification table as a whole, avoiding or reducing damage to the paper during the transfer process.

[0046] The paper deacidification workbench is equipped with a deacidification solution mixing tank, which is also equipped with a stirrer and a heater. The stirrer can fully stir the deacidification solution, and the heater can raise the solution to an appropriate temperature to achieve the best deacidification effect.

[0047] The paper deacidification operating table is equipped with a constant pressure quantitative module. This module includes a gear pump, a motor, a pressure accumulator, and a solenoid valve. The gear pump is a quantitative pump that ensures the discharged solution volume is the required volume, thus achieving quantitative control. The module also has a pressure sensor. When the pressure of the solution pumped by the gear pump reaches the required level, the pressure sensor collects the pressure in the pipeline, and the control system controls the solenoid valve to open, ensuring the discharged solution meets the required quantitative volume and pressure. The pressure accumulator is used because fluctuations in the gear pump's speed will cause fluctuations in the pumped liquid flow and pressure. Connected in series in the pipeline, the pressure accumulator's internal compressed air quickly compensates for pressure changes, preventing large pressure fluctuations and stabilizing the pipeline pressure. The solenoid valve is used because the initial pressure of the liquid pumped by the pump is relatively low. Connecting the solenoid valve in series in the pipeline closes the pipeline, and opens it again when the required pressure is reached.

[0048] The paper deacidification workbench is equipped with a nozzle that can spray a mist of liquid to ensure that the liquid sprayed in a certain area is evenly sprayed on the paper. Since the uniformity of the spray is greatly affected by the liquid pressure in the pipeline, the pressure in the liquid pipeline is required to be stable.

[0049] The paper deacidification operating table is equipped with a planar motion module, which can realize movement in the X and Y directions in the plane. At the same time, the planar motion module is fixed with the nozzle, so that it can work with the metering device to meter and evenly spray the spray from the nozzle onto the paper tray.

[0050] The paper deacidification workbench is equipped with a paper tray vacuum base. The inside of the base is a cavity, which is connected to a vacuum pump through a pipeline to achieve a negative pressure effect inside the cavity. The paper tray vacuum base is also equipped with a sealing ring around its perimeter. The sealing ring is connected to the paper tray upwards, so that a negative pressure cavity can be formed between the paper tray, the sealing ring, and the paper tray vacuum base.

[0051] The paper tray has three grooves with multiple through holes that communicate with the negative pressure chamber. During the deacidification process, the vacuum pump starts working, and the negative pressure is used to hold the paper in place through the multiple through holes in the grooves of the paper tray, preventing the paper from moving or curling during the deacidification process and ensuring flatness and uniformity of deacidification. When the deacidification is completed, the vacuum pump stops working, the negative pressure chamber returns to normal atmospheric pressure, and the robotic arm can then smoothly transport the paper tray to the drying table.

[0052] III. Drying process:

[0053] The robotic arm uses a paper tray gripper on its multi-functional robotic arm at the front end to lift and lock the paper tray on the deacidification operating table and place it in the correct position on the paper drying table; then the robotic arm releases the paper tray by releasing the paper tray from the multi-functional robotic arm at the front end.

[0054] A heating water tank is installed on the paper drying table. The heater can raise the solution to a suitable temperature and provide hot water for drying on the paper drying table.

[0055] A water pump is installed on the paper drying table, which circulates the hot water used for drying and finally returns it to the hot water tank;

[0056] The paper drying table is equipped with a water bath heating tray. The paper tray is located above the water bath heating tray and is in contact with the water bath heating tray, so that the heat of the water bath heating tray can be transferred to the paper tray, thereby heating the paper tray and drying the deacidified paper on the paper tray.

[0057] The paper drying table is equipped with a temperature sensor to monitor the temperature of the water bath heating tray and prevent the temperature from being too high or too low during the drying process.

[0058] The paper drying table is equipped with multiple drying tables. Since the drying time is longer than the deacidification time, multiple paper trays can be dried at the same time, thus improving the efficiency of the entire system.

[0059] The multi-layer drying platform is connected by pipes at both ends. The first section of the water pipe of the entire module is connected to the water pump, and the last section of the water pipe of the entire module is connected to the water tank, thereby realizing the water circulation of the entire module.

[0060] IV. Robotic arm handling:

[0061] The robotic arm has four degrees of freedom: movement in the X, Y, and Z directions, and rotation about the Z-axis.

[0062] The robotic arm is equipped with a multi-functional robotic hand: namely, the handling of paper trays and the adsorption of single sheets of paper;

[0063] The robotic arm is equipped with a multi-functional gripper, featuring a gripper plate, electromagnetic push rods, and a vacuum suction cup. The gripper plate has circular holes of the same size and spacing as the holes on the paper tray. Electromagnetic push rods are mounted on these holes. When the robotic arm moves the gripper plate to align with the holes on the paper tray, the movement is considered complete. At this point, two electric push rods activate, with the electromagnetic push rods pushing internal push rods into the circular holes on the paper tray, thus locking the paper tray in place. The two electromagnetic push rods also limit the rotation of the paper tray, ensuring stability during transport.

[0064] The multi-functional robotic arm is equipped with six vacuum suction cups, which can be used to pick up and hold paper.

[0065] The height of the vacuum suction cup on the multi-functional robotic arm is higher than that of the paper tray clamp, so the paper tray clamp will not affect the paper adsorption process.

[0066] When moving the paper tray, the electromagnetic push rod is in front and the vacuum suction cup is behind, so the vacuum suction cup will not affect the movement of the paper tray during the process.

[0067] In summary, this invention employs a robotic arm for efficient paper laying and integrates the transfer of paper and paper tray, improving paper laying efficiency, reducing labor costs, and minimizing damage during paper transfer. A quantitative pump and planar motion module ensure precise and uniform spraying of the deacidifying solution onto the paper surface. A hydrothermal temperature-controlled drying device enables visualized and precise temperature control, while the multi-layered drying platform significantly enhances drying efficiency. The integrated robotic arm-assisted paper preparation, deacidification, and drying system ensures efficient operation, reduces manpower, and provides precise work.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
