Description

Films are used in a wide range of applications, from food packaging in daily life to electronic component protection in industry to pharmaceutical packaging. Different applications impose varying quality requirements on films, which also extend to every step of the film production process, with the winding process being particularly critical. Traditional film winding systems primarily focus on achieving basic winding functions: orderly winding the produced film for storage, transportation, and subsequent processing. These universal winding structures often fail to consider the specific requirements of films in different application scenarios. For example, in the pharmaceutical field, the use of films presents unique challenges. Pharmaceutical films must not only meet basic physical property requirements, such as flexibility and transparency, but more importantly, ensure high hygienic properties. This is because pharmaceutical products are extremely sensitive to microbial contamination, and microbial contamination of the film can compromise the quality and safety of the drug.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] Existing film winding structures have significant drawbacks when applied to pharmaceutical film. The pharmaceutical industry places extremely stringent requirements on film sterility, yet existing film winding structures lack effective aseptic processing mechanisms. During actual production and winding, films are susceptible to contamination by microorganisms in the surrounding environment. For example, airborne bacteria and fungi can adhere to the film surface, seriously threatening the quality and safety of pharmaceutical films.

[0030] like Figure 1 As shown, the present invention provides a film aseptic winding structure, including a bacteria isolation chamber 1, a temporary storage chamber 2, a conveying structure 3, a winding device 4, a transfer structure 5 and a discharge structure 6. One side of the bacteria isolation chamber 1 is connected to the temporary storage chamber 2, and the temporary storage chamber 2 is provided with an inlet 11 on the upper side and a discharge port 12 on the lower side on the side where the bacteria isolation chamber 1 is connected. The conveying structure 3 is connected to the inlet 11, and the conveying structure 3 is used to convey the unwound winding roller. The other side of the bacteria isolation chamber 1 is connected to the winding device 4, and the winding device 4 is used to roll the winding roller. The transfer structure 5 is suspended above the bacteria isolation chamber 1, and the discharge structure 6 is below the bacteria isolation chamber 1. The discharge structure 6 is used to output the finished product, and the finished product passes through the discharge structure The structure 6 is positioned at the discharge port 12, and isolation door structures 8 are respectively provided at the discharge port 12 and the feed port 11. The transfer structure 5 includes a lifting manipulator 51 and a clamping unit 52. The ends of the lifting manipulator 51 are respectively positioned above the feed port 11 and the winding device 4, and reciprocate. The clamping unit 52 is located at the output end of the lifting manipulator 51 and is used to clamp the winding roller or finished product. The conveying structure 3 includes a conveying device 31 and a processing device 32. The processing device 32 is mounted outside the conveying device 31 and is used to remove dust and static electricity from the winding roller. A sterilization device is installed in the temporary storage chamber 2, and the sterilization chamber 1 and / or the temporary storage chamber 2 are equipped with multiple isolation glove boxes 7. During operation, the unwound winding roller is first transported by the conveying device 31 of the conveying structure 3. During transportation, the processing device 32 removes dust and static electricity from the winding roller. After treatment, the winding roller enters the temporary storage chamber 2, where the sterilization device in the temporary storage chamber 2 sterilizes the winding roller. Then, the winding roller is clamped by the lifting manipulator 51 of the transfer structure 5 and transported to the winding device 4 in the sterilization chamber 1 for winding. After the winding is completed, the lifting manipulator 51 clamps the finished product again and transports it to the discharge structure 6 for discharge preparation, and finally outputs it to the discharge port 12 through the discharge structure 6. The present invention removes dust and static electricity from the winding roller through the processing device 32 in the conveying structure 3, thereby reducing the risk of impurity adsorption and improving product quality. A sterilization device is set in the temporary storage room 2 to sterilize the winding roller. Combined with the design of multiple isolation glove boxes 7, the entire winding process is completed in the temporary storage room 2 and the sterilization chamber 1. After the winding roller enters the structure, it no longer interacts with the outside world, effectively avoiding external contamination. This comprehensive aseptic protection measure ensures that the entire winding structure is in a sterile environment, greatly improving the sterility of the film winding, thereby meeting the film production requirements that require a high sterile environment.

[0031] The lifting robot 51 in the transfer mechanism has a specific motion trajectory along the X and Y axes. In the X-axis, its movement covers the horizontal range from the feed inlet 11 to above the reel 4, ensuring accurate transfer of the reel or finished product between these two locations. In the Y-axis, given its position above the sterile chamber 1, its movement is primarily vertical. Specifically, the lifting robot 51 grasps the reel from the lower position of the feed inlet 11, rises to an appropriate height, then moves horizontally above the reel 4, and finally descends to place the reel on the reel 4.

[0032] The clamping section 52 is controlled by a pneumatic cylinder and consists of two clamping blocks that can move relative to each other. The clamping blocks, which come into contact with the winding roller or finished product, are made of medical-grade silicone. This material has excellent biocompatibility and antibacterial properties, preventing contamination of the film or winding roller. Furthermore, this material offers excellent flexibility and wear resistance, maintaining good performance during prolonged clamping operations, thereby ensuring stable clamping of the winding roller or finished product while meeting the requirements of a sterile environment.

[0033] The isolation glove box, housed within the sterile chamber 1 and / or the temporary storage chamber 2, is a relatively closed structure whose walls prevent air exchange between the inside and outside. The gloves sealed within the walls are sterile, flexible, and durable (e.g., made of special rubber or synthetic materials). Operators use the gloves to operate equipment and materials within (e.g., adjusting the winder position or performing simple equipment maintenance). This prevents microorganisms from entering the sterile area and causing contamination, even in a non-sterile environment.

[0034] The winding device 4 of the present invention is already in the prior art and will not be described in detail here.

[0035] Specifically, such as Figure 2As shown, the conveying device 31 of the present invention includes a conveying frame 311, a driving motor 312, an eccentric plate 313, a feeding rack 314 and an L-shaped inclined slide 315. The driving motor 312 is fixed on the conveying frame 311, and the eccentric plates 313 are respectively arranged on one side of the conveying frame 311. The driving motor 312 drives the eccentric plates 313 to rotate. One end of the feeding rack 314 is eccentrically connected to the eccentric plate 313, and the other end is provided with a placement port 3141. The placement port 3141 is used to place the winding roller. The upper end of the conveying frame 311 is provided with a transfer port 3111 matching the placement port 3141. The output end of the feeding rack 314 is connected to one end of the L-shaped inclined slide 315. The L-shaped inclined slide 315 is inclined and the other end passes through the temporary storage chamber 2 and is connected to the feeding port 11. The processing device 32 is fixedly connected to the conveying frame 311 and is sleeved above the feeding rack 314. Due to the eccentric connection between the feed rack 314 and the eccentric plate 313, the feed rack 314 of the present invention moves up and down relative to the conveyor frame 311 in an offset manner when the eccentric plate 313 rotates. The feed rack 314 is provided with multiple placement openings 3141 for placing the winding roller. Furthermore, a matching transfer opening 3111 is provided at the upper end of the conveyor frame 311. As the feed rack 314 moves up and down, the winding roller placed in the placement opening 3141 of the feed rack 314 is placed on the next transfer opening 3111 opposite it. Through this repeated transfer action, the winding roller is gradually transported on the conveyor frame 311. After passing between the feed rack 314 and the conveyor frame 311, the winding roller reaches the output end of the feed rack 314 and then enters the L-shaped inclined slide 315. The L-shaped inclined slide 315 is set at an angle. Relying on the action of gravity, the winding roller can slide smoothly along the L-shaped inclined slide 315, enter from one end thereof, pass through the temporary storage chamber 2 and reach the feed port 11, thereby preparing for the subsequent sterilization process.

[0036] The conveyor device 31 of the present invention achieves a unique motion of the feed frame 314 through the eccentric connection of the eccentric plate 313, thereby enabling efficient and orderly transfer of the winding rollers on the conveyor frame 311. This transfer method, unlike traditional linear or single chain conveyors, enables the sequential transfer of multiple winding rollers within a limited space, thereby improving conveying efficiency.

[0037] For further information, see Figure 1 and Figure 2The processing device 32 of the present invention includes an outer cover 321, a vacuum cleaner 322 and a plasma destaticizing device 323. The outer cover 321 is located above the feed rack 314 and is fixedly connected to the conveyor rack 311. The vacuum cleaner 322 and the plasma destaticizing device 323 are respectively fixedly connected to the outer cover 321. The present invention first uses the plasma destaticizing device 323 to remove static electricity from the surface of the winding roller to prevent static electricity from adsorbing dust and affecting the dust collection effect. Then, the dust on the surface of the winding roller is removed by the vacuum cleaner 322. The coordinated work of the two ensures the high efficiency and thoroughness of the winding roller in dust removal and static electricity removal. After pretreatment, the winding roller enters the subsequent sterilization treatment process, which can more effectively ensure the sterility effect and lay a good foundation for subsequent sterilization treatment.

[0038] If the winding roller slides too fast on the L-shaped inclined plate 315, it may not only affect its residence time in the temporary storage chamber 2 to receive sufficient sterilization treatment, but also directly collide with the bottom of the L-shaped inclined plate. Such collision may cause damage to the winding roller, such as deformation of the winding roller surface. Figure 3As shown, the conveying device 31 of the present invention also includes a buffer structure, comprising a buffer plate 316, a first bracket 317, a second bracket 318, and a flexible elastic member 319. Multiple notches 3151 are evenly distributed on the L-shaped inclined slide. One end of the buffer plate 316 is rotatably connected to the notches 3151. A first bracket 317 is positioned below the notches 3151. One end of the second bracket 318 is rotatably connected to the first bracket 317 and the other end is slidably connected to the end of the buffer plate 316 facing away from the notches 3151. One end of the flexible elastic member 319 is fixedly connected to the first bracket 317 and the other end is connected to the second bracket 318. When the winding roller slides downward along the L-shaped inclined slide, due to the buffer structure provided on the L-shaped inclined slide, if the winding roller moves too fast, it may come into contact with the buffer plate 316. Under the impact of the winding roller, the buffer plate 316 rotates about its pivotal connection point with the notches 3151. At this time, due to the sliding connection between the second bracket 318 and the buffer plate 316 and the rotational connection with the first bracket 317, and the flexible elastic member 319 connecting the first bracket 317 and the second bracket 318, the rotation of the buffer plate 316 is hindered. This obstruction absorbs some of the kinetic energy of the winding roller, thereby reducing the sliding speed of the winding roller. The buffer structure of the present invention reduces the speed of the winding roller through the aforementioned speed buffering mechanism, thereby preventing it from colliding with the bottom of the L-shaped inclined slide at high speed, effectively protecting the winding roller. Furthermore, because the buffer structure prevents the winding roller from sliding too quickly within the temporary storage chamber 2, the winding roller's presence within the temporary storage chamber 2 is prolonged. This feature facilitates the winding roller's thorough sterilization by the sterilization device 32. The sufficient residence time of the sterilization device 32 in the temporary storage chamber 2 ensures a more thorough sterilization effect, thereby enhancing sterility throughout the film winding process.

[0039] The flexible elastic member 319 uses a compressible gas (such as nitrogen or air) as an elastic medium, generating elastic force through volume changes within a sealed cavity. Its elasticity stems from the compression and expansion of the gas, resulting in nonlinear mechanical behavior, adjustable properties (controlled by pressure), and a buffering function. Compared to rigid elastic members based on the elastic deformation of metal materials, the flexible elastic member 319 provides a gentler buffering force. Therefore, the buffer plate 316 does not inflict significant impact upon the reel at the moment of contact, preventing damage and deformation to the reel surface during the buffering process. The flexible elastic member 319 employed in the present invention is a hydraulic damper.

[0040] Specifically, the buffer plate 316 and the L-shaped inclined slide are arranged at an angle, and the angle α between the two is equal to 2*the angle β between the L-shaped inclined slide and the horizontal plane. When the winding roller slides down the L-shaped inclined slide, the tilt angle of the buffer plate 316 can effectively decompose the impact force of the winding roller into multiple directional components. In the direction perpendicular to the buffer plate 316, due to the angle relationship of α=2*β, the impact force of the winding roller on the buffer plate 316 is not excessively concentrated in the vertical direction. When the winding roller contacts the buffer plate 316, the reaction force of the buffer plate 316 on the winding roller has an effective component along the direction of the L-shaped inclined slide, which is opposite to the direction of movement of the winding roller. Without this angular relationship, when the winding roller impacts the buffer plate 316 at a certain speed, the vertical impact force may be too large, easily causing damage to the buffer plate 316 or the winding roller. By setting this angle, the impact force is reasonably decomposed into different directions, reducing the concentration of impact force in the direction perpendicular to the buffer plate 316, thereby greatly reducing the possibility of severe collision when the winding roller contacts the buffer plate 316.

[0041] For further information, see Figure 1 , the sterilization device includes a gas device 21, a concentration detection device 22 and an exhaust fan 23 respectively fixed on the temporary storage chamber 2. The gas device 21 is used to transport sterilizing gas to the temporary storage chamber 2, the concentration detection device 22 is used to detect the gas concentration in the temporary storage chamber 2, and the exhaust fan 23 is used to exhaust the temporary storage chamber 2. The present application combines the gas device 21, the concentration detection device 22 and the exhaust fan 23 together and fixes them on the temporary storage chamber 2 to form a complete sterilization system. The present invention realizes an efficient and accurate sterilization process by adopting hydrogen peroxide gas as the sterilization gas and combining the coordinated work of the gas device 21, the concentration detection device 22 and the exhaust fan 23. At the same time, hydrogen peroxide gas as a sterilization gas has the advantages of fast sterilization speed and no residue, which further improves the sterilization efficiency.

[0042] In addition, if Figure 4As shown, the isolation door structure 8 of the present invention includes a door panel 81, a lifting cylinder 82, a slide rail 83, and a sterile cloth 84. The lifting cylinder 82 is fixedly connected to the temporary storage room 2 or the sterilization room 1. The lifting cylinder 82 drives the door panel 81 to move up and down. The door panel 81 is connected to the slide rail 83 and is located at the feed port 11 or the discharge port 12. The sterile cloth 84 is arranged on the other side of the feed port 11 or the discharge port 12 away from the door panel 81. The lifting cylinder 82 drives the door panel 81 to move up and down. When the door panel 81 is opened, the sterile cloth 84 plays its gas barrier role to prevent excessive entry of hydrogen peroxide gas. The closing of the door panel 81 directly cuts off the spatial connection between the temporary storage room 2 and the sterilization room 1, further ensuring the sterile state of the sterilization room 1. The slide rail 83 provides a stable guide for the lifting and lowering of the door panel 81, ensuring the accuracy and smoothness of the movement of the door panel 81. The present invention adds a sterile cloth 84 at the feed port 11 or the discharge port 12, which can more effectively prevent the influence of external gas (such as hydrogen peroxide gas in the temporary storage room 2) on the sterile environment of the sterile isolation chamber 1 while ensuring the normal entry and exit of materials, thereby improving the stability and reliability of the sterile environment of the sterile isolation chamber 1.

[0043] The upper end of the sterile cloth 84 is fixedly connected to the chamber surface, and a magnetic strip can be set at the lower end to connect to the chamber surface by magnetic attraction. When the roller moves, the sterile cloth 84 can pass through it. After the roller moves, the sterile cloth 84 can be connected to the chamber surface by attraction.

[0044] like Figure 5 As shown, the discharge structure 6 of the present invention comprises a discharge lift 61, a linear motion device 62, and a heat-sealing film device 63. The heat-sealing film device 63 is located within the sterilization chamber 1 and at the discharge port 12. The linear motion device 62 drives the discharge lift 61 to reciprocate between the winding device 4 and the heat-sealing film device 63. The discharge lift 61 is used to receive finished products. The dotted line in the figure shows the changing states of the discharge lift 61. The discharge structure 6 of the present invention achieves efficient finished product discharge and packaging through the coordinated operation of the discharge lift 61, the linear motion device 62, and the heat-sealing film device 63. The present invention integrates discharge, transportation, and film sealing and packaging operations into a single structural system, reducing intermediate links and improving work efficiency. Furthermore, film sealing and packaging are performed within the sterilization chamber 1, effectively preventing recontamination of the finished product and improving product quality. The discharge lift 61 and the linear motion device 62 provide excellent protection for the finished product during discharge, preventing damage to the coiled material during removal from the winding device 4 and during transportation.

[0045] Furthermore, the discharge lifting frame 61 includes a base 611, a discharge lifting cylinder 612, a scissor support frame 613, an oblique placement seat 614, a fixed plate 615, a movable plate 616 and a movable cylinder 617. The base 611 is slidably connected to the linear moving device 62. One end of the discharge lifting cylinder 612 is fixedly connected to the base 611 and the other end is fixedly connected to the oblique placement seat 614. One end of the scissor support frame 613 is connected to the base 611 and the other end is fixedly connected to the oblique placement seat 614. 4 is connected to one side of the discharge lifting cylinder 612. The side of the inclined placement seat 614 facing away from the discharge lifting cylinder 612 is inclined, with the end near the heat-sealing film device 63 being lower and the end near the winding device 4 being higher. A fixed plate 615 is fixed to the higher end of the inclined placement seat 614, and a movable plate 616 is located at the lower end of the inclined placement seat 614. A movable cylinder 617 is fixedly connected to the inclined placement seat 614 and drives the movable plate 616 to open and close relative to the inclined placement seat 614. When the air pressure within the discharge lifting cylinder 612 changes, the piston generates linear motion, thereby driving the inclined placement seat 614, to which it is fixed, to move up and down. When receiving finished products, the discharge lifting cylinder 612 raises the inclined placement seat 614 to an appropriate height below the winding device 4 so that the finished products can roll smoothly onto the inclined placement seat 614. This precise control of the height of the inclined placement seat 614 by the discharge lifting cylinder 612 ensures that the discharge lifting frame 61 can accurately receive finished products. During the lifting process, as the oblique placement seat 614 moves up and down, the angles between the various rods of the scissor support frame 613 change. This structure can effectively distribute the weight and load of the oblique placement seat 614 to the base 611, ensuring the stability of the lifting process.

[0046] The scissor structure, linear motion device and cylinder-controlled door panel opening and closing are already existing technologies and will not be described in detail in this application.

[0047] Because the inclined placement seat 614 is lower on the end near the heat-sealing film device 63 and higher on the end near the winding device 4, the finished product tends to roll toward the lower end when it is on the inclined placement seat 614. This allows the finished product to naturally roll toward the heat-sealing film device 63 without any additional external force when the discharge lift 61 reaches the heat-sealing film device 63. When the discharge lift 61 moves to the heat-sealing film device 63, the movable cylinder 617 drives the movable plate 616 to open and close relative to the inclined placement seat 614. Before the finished product rolls to the heat-sealing film device 63, the movable plate 616 is closed to prevent the finished product from rolling off prematurely. Once the discharge lift 61 accurately reaches the heat-sealing film device 63, the movable plate 616 opens, and the finished product rolls toward the heat-sealing film device 63 under its own weight. Once inside the heat-sealing film device 63, the vacuum heat-sealing operation can be performed. The sealed finished product continues to roll due to inertia (or the output driving force of the heat-sealing film device 63), eventually rolling out of the discharge port 12.

[0048] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
