Description

Technical Field

[0002] In modern industrial production, the production and application of films are very extensive. Films are widely used in various fields, from food packaging in daily life to electronic component protection in industry, to drug packaging in the medical field, etc. Different application fields have different quality requirements for films, which also extends to various links in the film production process, among which the winding link is particularly critical. In the traditional film winding structure, the main focus is on achieving the basic winding function, that is, winding the produced film in an orderly manner for storage, transportation and subsequent processing. This general winding structure mostly does not take into account the special needs of films in different application scenarios. For example, in the field of medicine, the use of films is special. Medical films must not only meet basic physical performance requirements, such as flexibility, transparency, etc., but more importantly, they must ensure a high degree of hygiene. This is because pharmaceutical products are extremely sensitive to microbial contamination. Once the film is contaminated by microorganisms, it may affect the quality and safety of the drug.

DETAILED DESCRIPTION

[0021] 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 construed as limiting the present invention.

[0022] The existing film winding structure has significant defects when applied to medical film winding. The pharmaceutical industry has extremely strict requirements on the sterility of films, but the existing film winding structure lacks an effective aseptic processing mechanism. During actual production and winding, the film is easily contaminated by microorganisms in the surrounding environment. For example, bacteria and fungi in the air may adhere to the surface of the film, which seriously threatens the quality and safety of medical films.

[0023] like Figure 1As 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. The temporary storage chamber 2 is connected to the bacteria isolation chamber 1. A feed port 11 is provided above the side where the bacteria isolation chamber 1 is connected. A discharge port 12 is provided below the side. The conveying structure 3 is connected to the feed port 11. The conveying structure 3 is used to convey a winding roller that has not been wound. The other side of the bacteria isolation chamber 1 is connected to the winding device 4. The winding device 4 is used to roll the winding roller. The transfer structure 5 is suspended above the bacteria isolation chamber 1. The discharge structure 6 is located below the bacteria isolation chamber 1. The discharge structure 6 is used to output the finished product. The finished product passes through the discharge structure The structure 6 is placed at the discharge port 12, and the discharge port 12 and the feed port 11 are respectively provided with an isolation door structure 8; the transfer structure 5 includes a lifting manipulator 51 and a clamping part 52, the two ends of the lifting manipulator 51 are respectively located above the feed port 11 and the winding device 4 and make reciprocating motions, and the clamping part 52 is arranged at the output end of the lifting manipulator 51, and the clamping part 52 is used to clamp the winding roller or the finished product; the conveying structure 3 includes a conveying device 31 and a processing device 32, the processing device 32 is sleeved outside the conveying device 31, and the processing device 32 is used to remove dust and static electricity from the winding roller; a sterilization device is provided in the temporary storage room 2, and a plurality of isolation glove boxes 7 are provided in the sterilization room 1 and / or the temporary storage room 2. During the working process, the unwound winding roller is first conveyed by the conveying device 31 of the conveying structure 3, and during the conveying process, the processing device 32 removes dust and static electricity from the winding roller. The treated winding roller enters the temporary storage room 2, and the sterilization device in the temporary storage room 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 winding is completed, the lifting manipulator 51 clamps the finished product again and transports it to the discharging structure 6 for discharging preparation, and finally outputs it to the discharging port 12 through the discharging 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, and combined with the design that multiple isolation glove boxes 7 can be set, 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 improves the sterility of the film winding, and thus meets the film production requirements with high requirements for a sterile environment.

[0024] The lifting manipulator 51 in the transfer structure has a specific motion trajectory in the XY axis direction. In the X axis direction, its movement covers the horizontal range from the feed port 11 to the top of the winding device 4, so as to ensure the accurate transfer of the winding roller or finished product between these two positions. In the Y axis direction, since it is suspended above the sterilization chamber 1, its movement is mainly vertical up and down. Specifically, after the lifting manipulator 51 grabs the winding roller from the lower position of the feed port 11, it rises to a suitable height, then moves horizontally to the top of the winding device 4, and finally descends to place the winding roller on the winding device 4.

[0025] The clamping part 52 is controlled by a cylinder and includes two clamping blocks that can move relative to each other. The clamping block uses medical grade silicone as the material that contacts the winding roller or the finished product. Medical grade silicone has good biocompatibility and antibacterial properties and will not contaminate the film or the winding roller. At the same time, the material has excellent flexibility and wear resistance, and can maintain good performance during long-term clamping operations, thereby ensuring stable clamping of the winding roller or the finished product and meeting the requirements of a sterile environment.

[0026] The isolation glove box is placed in the sterile room 1 and / or the temporary storage room 2. It is a relatively closed structure, and the box wall can block the air exchange between the inside and the outside. The gloves sealed by the box wall are sterile, flexible and not easy to be damaged (such as special rubber or synthetic materials). Operators use gloves to operate internal equipment or materials (such as adjusting the position of the winding roller, simple maintenance of equipment), even if the external environment is non-sterile, it can prevent microorganisms from entering the sterile area and causing contamination.

[0027] The winding device 4 of the present invention is already a prior art and will not be described in detail here.

[0028] Specifically, 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 plate 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 plate 315. The L-shaped inclined slide plate 315 is inclined and the other end passes through the temporary storage chamber 2 and is connected to the feed 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 relationship between the feed rack 314 of the present invention and the eccentric plate 313, when the eccentric plate 313 rotates, the feed rack 314 will move up and down relative to the conveyor frame 311 in a dislocated manner. The feed rack 314 is provided with a plurality of placement openings 3141, and these placement openings 3141 are used to place the winding roller. At the same time, a matching transfer opening 3111 is provided at the upper end of the conveyor frame 311. When the feed rack 314 moves up and down, the winding roller placed in the placement opening 3141 of the feed rack 314 will be placed on the next transfer opening 3111 opposite to it, and through such repeated transfer actions, the winding roller is gradually transferred on the conveyor frame 311. After being transferred by 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 plate 315. The L-shaped inclined slide plate 315 is tilted, and relying on the effect of gravity, the winding roller can slide smoothly along the L-shaped inclined slide plate 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.

[0029] The conveying device 31 of the present invention realizes a special movement mode of the feeding frame 314 through the eccentric connection between the eccentric plate 313 and the feeding frame 314, thereby realizing efficient and orderly transfer of the winding roller on the conveying frame 311. This transfer mode is different from the traditional linear or single chain conveying, and can realize the sequential transfer of multiple winding rollers in a limited space, thereby improving the conveying efficiency.

[0030] 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 feeding 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 on the surface of the winding roller to avoid static electricity 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 sterilization effect and lay a good foundation for the subsequent sterilization treatment.

[0031] If the winding roller slides too fast on the L-shaped inclined plate 315, it may not only affect its stay 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 further includes a buffer structure, which includes a buffer plate 316, a first bracket 317, a second bracket 318 and a flexible elastic member 319. A plurality of notches 3151 are evenly arranged on the L-shaped inclined slide. One end of the buffer plate 316 is rotatably connected to the notch 3151. The first bracket 317 is arranged below the notch 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 away from the notch 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 will contact the buffer plate 316. Under the impact of the winding roller, the buffer plate 316 will rotate around its rotation connection point with the notch 3151. At this time, due to the sliding connection between the second bracket 318 and the buffer plate 316 and the rotational connection relationship 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 will be hindered. This hindering effect can absorb part 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 above-mentioned speed buffer mechanism, thereby avoiding the occurrence of the situation that it collides with the bottom of the L-shaped inclined slide plate at high speed, and effectively protects the winding roller. In addition, since the buffer structure can prevent the winding roller from sliding too fast in the temporary storage chamber 2, the existence time of the winding roller in the temporary storage chamber 2 can be extended. This feature provides favorable conditions for the winding roller to be fully sterilized by the sterilization treatment device 32. In the temporary storage chamber 2, when the sterilization treatment device 32 sterilizes the winding roller, sufficient residence time can ensure that the sterilization effect is more thorough, thereby improving the sterility guarantee during the entire film winding process.

[0032] The flexible elastic member 319 is a device that uses compressible gas (such as nitrogen or air) as an elastic medium and generates elastic force through the change of gas volume in a closed cavity. Its elasticity comes from the compression and expansion of the gas, and its mechanical behavior is nonlinear. It has adjustability (through pressure control) and buffering functions. Compared with rigid elastic members based on the elastic deformation of metal materials, the buffering force that the flexible elastic member 319 can provide is softer. Therefore, the buffer plate 316 will not cause too much impact force to it at the moment of contact with the winding shaft, avoiding damage and deformation of the shaft surface during the buffering process. The flexible elastic member 319 used in the present invention is a hydraulic damper.

[0033] Specifically, the buffer plate 316 and the L-shaped inclined slide plate are set at an angle, and the angle α between the two is 2*the angle β between the L-shaped inclined slide plate and the horizontal plane. When the winding roller slides down along the L-shaped inclined slide plate, the inclination angle of the buffer plate 316 can effectively decompose the impact force of the winding roller into components in multiple directions. In the direction perpendicular to the buffer plate 316, due to the angle relationship of the angle α=2*β, the impact force of the winding roller on the buffer plate 316 will not be 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 in the direction along the L-shaped inclined slide plate, and this component is opposite to the movement direction of the winding roller. If there is no such angle relationship, when the winding roller impacts the buffer plate 316 at a certain speed, the impact force in the vertical direction may be too large, which may easily cause 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 a violent collision when the winding roller contacts the buffer plate 316.

[0034] 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.

[0035] 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 sterile isolation 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 lifting and lowering of the door panel 81. When the door panel 81 is opened, the sterile cloth 84 plays its gas barrier role to prevent excessive entry of hydrogen peroxide gas; and the closing of the door panel 81 directly cuts off the spatial connection between the temporary storage room 2 and the sterile isolation room 1, further ensuring the sterile state of the sterile isolation room 1. The slide rail 83 provides a stable guide for the lifting and lowering of the door panel 81, ensuring the accuracy and stability 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 room 1 while ensuring the normal material entry and exit, thereby improving the stability and reliability of the sterile environment of the sterile isolation room 1.

[0036] 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 with 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 with the chamber surface by attraction.

[0037] like Figure 5 As shown, the discharging structure 6 of the present invention comprises a discharging lifting frame 61, a linear moving device 62 and a heat-sealing film device 63. The heat-sealing film device 63 is arranged in the bacteria isolation chamber 1 and is located at the discharging port 12. The linear moving device 62 drives the discharging lifting frame 61 to reciprocate between the bottom of the winding device 4 and the heat-sealing film device 63. The discharging lifting frame 61 is used to receive the finished product. The dotted line in the figure is the changing state of the discharging lifting frame 61. The discharging structure 6 of the present invention realizes an efficient finished product discharging and packaging process through the coordinated work of the discharging lifting frame 61, the linear moving device 62 and the heat-sealing film device 63. The present invention integrates the operations of discharging, transportation and film sealing packaging into a structural system, reduces the intermediate links and improves the work efficiency. At the same time, the film sealing packaging is carried out in the bacteria isolation chamber 1, which effectively avoids the finished product from being contaminated again and improves the quality of the product. The discharging lifting frame 61 and the linear moving device 62 play a good protective role on the finished product during the discharging process of the finished product, avoiding damage to the coiled material during the removal of the finished product from the winding device 4 and the transportation process.

[0038] Furthermore, the discharging lifting frame 61 includes a base 611, a discharging 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 discharging 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 connected to the oblique placement seat 61 4 is connected to one side of the discharging lifting cylinder 612, the side of the oblique placement seat 614 away from the discharging lifting cylinder 612 is an inclined surface, and the end close to the heat sealing film device 63 is low and the end close to the winding device 4 is high, the fixed plate 615 is fixed to the high end of the oblique placement seat 614, the movable plate 616 is at the low end of the oblique placement seat 614, and the movable cylinder 617 is fixedly connected to the oblique placement seat 614 and drives the movable plate 616 to open and close relative to the oblique placement seat 614. When the air pressure in the discharging lifting cylinder 612 changes, the piston produces a linear motion, thereby driving the oblique placement seat 614 fixedly connected to it to move up and down. When receiving the finished product, the discharging lifting cylinder 612 raises the oblique placement seat 614 to a suitable height below the winding device 4 so that the finished product can smoothly roll onto the oblique placement seat 614. This method of accurately controlling the height of the oblique placement seat 614 by the discharging lifting cylinder 612 ensures that the discharging lifting frame 61 can accurately receive the finished product. During the lifting process, as the oblique placement seat 614 moves up and down, the angles between the rods of the scissor support frame 613 change. This structure can effectively distribute the weight of the oblique placement seat 614 and the load it bears to the base 611, ensuring the stability of the lifting process.

[0039] The scissor structure, the linear moving device and the cylinder controlling the opening and closing of the door panel are already existing technologies and will not be elaborated in this application.

[0040] Since the end of the oblique placement seat 614 close to the heat-sealing film device 63 is low and the end close to the winding device 4 is high, the finished product has a tendency to roll toward the lower end when it is located on the oblique placement seat 614, so that the finished product can naturally roll toward the heat-sealing film device 63 without additional external force when the discharge lifting frame 61 reaches the heat-sealing film device 63. When the discharge lifting frame 61 moves to the heat-sealing film device 63, the moving cylinder 617 drives the moving plate 616 to open and close relative to the oblique placement seat 614. Before the finished product rolls to the heat-sealing film device 63, the moving plate 616 is in a closed state to prevent the finished product from rolling down prematurely. When the discharge lifting frame 61 accurately reaches the heat-sealing film device 63, the moving plate 616 opens, and the finished product rolls toward the heat-sealing film device 63 under the action of its own weight. After entering the heat-sealing film device 63, the vacuum heat-sealing film operation can be performed. The finished product after film sealing continues to roll with inertia (or the output driving force of the heat-sealing film device 63) and finally rolls out of the discharge port 12. What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
