Description

Technical Field

[0001] This invention relates to the field of pharmaceutical production equipment technology, and in particular to a pharmaceutical bottle filling production line. Background Technology

[0002] In the current field of small-bottle liquid filling machinery, the variety of complete production lines on the market is relatively limited, and most designs exhibit a high degree of similarity, which to some extent restricts the pace of industry innovation and technological progress. Traditional production line configurations typically include basic components, such as a bottle unscrambler responsible for the orderly supply of bottles, a filling machine that relies on ceramic plunger pumps or gear pumps for quantitative filling, followed by a capping and coring unit to complete the sealing operation. However, a significant drawback is the lack of integrated bottle washing equipment in these production lines. This means that bottle cleaning and filling are two completely separate steps, and the failure to integrate these two processes into a single production line increases operational complexity and costs. Furthermore, the filling needles cannot be sterilized during mass production without stopping the machine.

[0003] Insufficient bottle cleanliness is a common problem on the production line, which directly affects product quality and consumer acceptance. Summary of the Invention

[0128] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0129] The purpose of this invention is to provide a pharmaceutical bottle filling production line to solve the problems existing in the prior art and reduce the cost of pharmaceutical filling production.

[0130] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0131] like Figure 1 As shown, this embodiment provides a pharmaceutical bottle filling production line 10000, which includes a bottle unscrambler 1000, an airflow cleaning machine 2000, a filling machine 3000, and a stopper and capping device 4000 connected in sequence.

[0132] like Figures 2 to 7 As shown, in this embodiment, the bottle unscrambler 1000 includes:

[0133] Bottle container 1, used for storing medicine bottles 603;

[0134] The bottle feeding mechanism includes a bottle dispensing conveyor belt 2 and a bottle feeding chute 3. The bottle dispensing conveyor belt 2 is used to transport the medicine bottles 603 in the storage hopper 1 to the bottle feeding chute 3.

[0135] The dividing cone plate 10 is inclined axially;

[0136] Bottle sorting and unscrambling drive motor 21 for driving the rotation of the bottle sorting cone plate 10;

[0137] The bottle-feeding ring 6 is annular and is fitted around the bottle-separating cone plate 10. The inner edge of the bottle-feeding ring 6 is in clearance fit with the outer edge of the bottle-separating cone plate 10. The higher end of the edge of the bottle-separating cone plate 10 is higher than the top surface of the bottle-feeding ring 6, and the lower end of the edge of the bottle-separating cone plate 10 is lower than the top surface of the bottle-feeding ring 6. The top surface of the bottle-feeding ring 6 has radial through grooves 601 evenly distributed circumferentially for accommodating medicine bottles 603. There is a gap between two adjacent radial through grooves 601. When the medicine bottle 603 is located in the radial through groove 601, the axial direction of the medicine bottle 603 is the same as the radial direction of the bottle-feeding ring 6. The outer edge of the bottle-feeding ring 6 has vertical through grooves 602 evenly distributed circumferentially for accommodating medicine bottles 603. When the medicine bottle 603 is located in the vertical through groove 602, the axial direction of the medicine bottle 603 is parallel to the axial direction of the bottle-feeding ring 6.

[0138] Bottle-scraping drive mechanism for driving the bottle-scraping ring belt 6 to rotate;

[0139] The bottle pushing mechanism is used to gradually push the pharmaceutical bottles 603 on the radial through groove 601 into the vertical through groove 602; the position where the pharmaceutical bottles 603 on the bottle feeding ring 6 fall into the vertical through groove 602 is the drop point;

[0140] The discharge conveying assembly 8 includes a pallet 801, a discharge conveyor belt 802, and a discharge guide trough 803 located above the discharge conveyor belt 802. The discharge guide trough 803 and the discharge conveyor belt 802 are respectively connected to the discharge end of the bottle unscrambling ring belt 6. One end of the pallet 801 is located directly below the drop point, and the other end is connected to the feed end of the discharge conveyor belt 802.

[0141] In a preferred embodiment, the system further includes a bottle unscrambler frame 5, on which the bottle unscrambler drive motor 21, the bottle unscrambler drive mechanism, and the discharge conveyor assembly 8 are respectively mounted. The bottle unscrambler frame 5 provides stable support for the bottle unscrambler drive motor 21, the bottle unscrambler drive mechanism, and the discharge conveyor assembly 8.

[0142] In the optional embodiments of this example, a more preferred option is to include a bottle-removing mechanism. The bottle-removing mechanism includes a bottle-removing motor 16 and a plurality of bottle-pushing teeth 17 distributed circumferentially along the output shaft of the bottle-removing motor 16. Each bottle-pushing tooth 17 is fixedly connected at one end to the output shaft of the bottle-removing motor 16. The bottle-removing motor 16 is fixedly connected to the bottle-scraping frame 5 through a support frame 15 and is located directly above the bottle-scraping ring belt 6. The output shaft of the bottle-removing motor 16 is horizontal and radially tangent to the bottle-scraping ring belt 6. The gap between the bottom end of the lowest bottle-pushing tooth 17 and the top surface of the bottle-scraping ring belt 6 is smaller than the diameter of the medical bottle 603. The bottle-pushing tooth 17 is used to push the medical bottle 603 located above the bottle-scraping ring belt 6 and not completely located in the radial through groove 601 toward the bottle-separating cone plate 10.

[0143] During the bottle sorting process, the bottle-removing motor 16 drives the bottle-pushing toothed plate 17 to rotate. The bottle-pushing toothed plate 17 accurately removes those medical bottles 603 that fail to fall into the radial through groove 601 correctly and pushes them back to the bottle-separating cone plate 10, ensuring the purity and efficiency of the bottle sorting process.

[0144] In a preferred embodiment, the system further includes a first baffle plate 14 fixed to the bottle unscrambler frame 5. The first baffle plate 14 is annular, with its inner wall facing the bottle-removing mechanism, and the top of the bottle-separating cone plate 10 located between the first baffle plate 14 and the bottle-removing mechanism. The first baffle plate 14 prevents splashing or scattering that may occur during bottle unscrambling. Especially at high speeds, the first baffle plate 14 can block the pharmaceutical bottles 603 that are moved by the bottle-removing teeth 17, protecting the safety of the operator and keeping the work area clean.

[0145] In the optional scheme of this embodiment, it is more preferred that the bottom end of the bottle storage hopper 1 is provided with a discharge port, the bottom end of the bottle discharge conveyor belt 2 is provided at the discharge port of the bottle storage hopper 1, the bottle discharge conveyor belt 2 is inclined, and multiple scraper plates 9 are provided at intervals on the bottle discharge conveyor belt 2; the bottle feeding chute 3 is inclined, and the discharge port of the bottle feeding chute 3 faces the higher end of the edge of the bottle separating cone plate 10.

[0146] In an optional embodiment, a more preferred embodiment is that a flexible second baffle 7 is provided at the outlet of the bottle feeding chute 3, with only its top end connected to the top end of the bottle feeding chute 3. The second baffle 7 can block the rapidly sliding medical bottle 603 at the outlet of the bottle feeding chute 3, reduce its movement speed, and prevent the medical bottle 603 from moving too fast and moving outside the equipment.

[0147] In the optional solutions of this embodiment, it is more preferred that the material of the second baffle 7 is plastic; the plastic material has a certain degree of flexibility, which allows the second baffle 7 to provide a certain buffering effect when blocking the medical bottle 603, reducing the impact force when the bottle contacts the baffle, and avoiding damage to the bottle or unnecessary noise.

[0148] It is worth noting that in this embodiment, an annular baffle plate 4 is also provided directly above the bottle-feeding ring belt 6. The baffle plate 4 is coaxial with the bottle-feeding ring belt 6. The function of the baffle plate 4 is to enclose the columnar space directly above the bottle-feeding ring belt 6 to prevent the medical bottles 603 from splashing out of the device due to movement and collision during the bottle feeding process. At the same time, in order to facilitate the setting of the bottle-removing mechanism, the baffle plate 4 is also provided with a notch corresponding to the bottle-removing mechanism.

[0149] In a preferred embodiment, the bottle-scraping drive mechanism includes a connecting ring 20, a bottle-scraping drive motor 21, and multiple support mechanisms circumferentially spaced on the bottle-scraping frame 5. Each support mechanism includes a vertical support rod 23, a first roller 24, and a second roller 25. The first roller 24 and the second roller 25 are respectively mounted on the vertical support rod 23. The first roller 24 rolls with the bottom end of the connecting ring 20, and the second roller 25 rolls with the outer wall of the connecting ring 20. The bottle-scraping drive motor 21 is fixed to the bottle-scraping frame 5, and a friction wheel 22 is fixed to the output shaft of the bottle-scraping drive motor 21. The friction wheel 22 rolls with the inner wall of the connecting ring 20. The bottle-scraping belt 6 is coaxial with the connecting ring 20, and the bottom end of the bottle-scraping belt 6 is fixedly connected to the top end of the connecting ring 20. The combination of the bottle-scraping drive motor 21 and the friction wheel 22, along with the stable support of the connecting ring 20 and the support mechanisms, achieves smooth rotation and precise control of the bottle-scraping belt 6, ensuring the stability and efficiency of the bottle-scraping process.

[0150] In the optional solutions of this embodiment, the preferred option is that the bottle pushing mechanism includes a bottle pushing plate 11 disposed above the bottle feeding ring 6. The bottle pushing plate 11 is ring-shaped, and the distance between the first end and the second end of the bottle pushing plate 11 and the outer edge of the bottle feeding ring 6 gradually decreases, as does the distance between the first end and the second end of the bottle pushing plate 11 and the top surface of the bottle feeding ring 6.

[0151] Since the bottle pusher plate 11 is located above the bottle unscrambler belt 6, during the rotation of the bottle unscrambler belt 6, the pusher plate can gradually push the pharmaceutical bottles 603 on the radial through groove 601 into the vertical through groove 602, ensuring that the pharmaceutical bottles 603 can accurately fall into the vertical through groove 602 at the drop point. It should be noted that during the process of the pharmaceutical bottles 603 falling from the radial through groove 601 into the vertical through groove 602, under the action of their own gravity, they will fall into the vertical through groove 602 with the bottom facing down and the mouth facing up.

[0152] It should be noted that, although ideally, only one annular pusher plate 11 is needed to gradually push the medicine bottle 603 in the radial channel 601 into the radial channel 601, there are often many obstacles in real-world applications. Therefore, in practical applications, multiple pusher plates 11 can be set up to achieve this function according to actual needs. Each pusher plate 11 is usually an incomplete annulus, as shown in the figure.

[0153] In the optional embodiments of this invention, a preferred option is that the bottom end of the pusher plate 11 is covered with a scratch-resistant layer, the material of which is foam or fabric. The scratch-resistant layer can reduce friction when the pusher plate 11 is in direct contact with the surface of the pharmaceutical bottle 603, and avoid scratches or damage to the bottle body during the pusher process. This protective measure is especially important for bottles with smooth or fragile surfaces.

[0154] In the optional scheme of this embodiment, a more preferred embodiment is that a vertical arc-shaped baffle 18 and a horizontal arc-shaped baffle 19 are also provided at the discharge point of the bottle-scraping belt 6. The vertical arc-shaped baffle 18 is arranged along the outer circumference of the bottle-scraping belt 6 and is fixedly connected to the bottle-scraping frame 5. The function of the vertical arc-shaped baffle 18 is to prevent the pharmaceutical bottles 603 in the vertical channel 602 from being thrown out of the vertical channel 602 under the action of centrifugal force. The horizontal arc-shaped baffle 19 is also fixedly connected to the bottle-scraping frame 5. The function of the horizontal arc-shaped baffle 19 is to facilitate the connection of the discharge conveying assembly 8.

[0155] It should be noted that the bottle unscrambler 1000 in this embodiment is particularly suitable for unscrambling eye drop bottles, and can also be used for unscrambling other medical bottles 603 that are similar in shape to eye drop bottles.

[0156] like Figures 8 to 14 As shown, in this embodiment, the airflow cleaning machine 2000 includes:

[0157] The bottle feeding mechanism includes a bottle feeding conveyor belt, a bottle feeding screw 27, and a first screw-in turntable 28. The bottle feeding screw 27 is rotatably mounted above the bottle feeding conveyor belt. The outer edge of the first screw-in turntable 28 is provided with multiple first slots, and the bottles to be cleaned on the bottle feeding conveyor belt can be inserted into the first slots at the discharge end of the bottle feeding conveyor belt.

[0158] The cleaning mechanism includes a cleaning turntable 47, a dust collection tank 30, and multiple cleaning modules arranged circumferentially along the cleaning turntable 47. The cleaning turntable 47 is provided with multiple second slots circumferentially, and the cleaning modules correspond one-to-one with the second slots. The cleaning modules are located directly above the corresponding second slots. The bottle that is inserted into the first slot can be inserted into the second slot at the junction of the first screw-in turntable 28 and the cleaning turntable 47. The cleaning modules are used to blow compressed air into the bottle space inside the bottle in the corresponding second slot. The dust collection tank 30 is connected to a first negative pressure device and is used to collect foreign objects blown out from the bottle space.

[0159] The bottle dispensing mechanism includes a bottle dispensing conveyor belt, a bottle dispensing screw 33, and a first dispensing turntable 31. The bottle dispensing screw 33 is rotatably mounted above the bottle dispensing conveyor belt. The outer edge of the first dispensing turntable 31 is provided with multiple third slots. Bottles that are inserted into the second slots can be inserted into the third slots at the junction of the first dispensing turntable 31 and the cleaning turntable 47. Bottles inserted into the third slots can enter the bottle dispensing conveyor belt at the feed end of the bottle dispensing conveyor belt.

[0160] The second support 26 houses the bottle feeding mechanism, the cleaning mechanism, and the bottle dispensing mechanism.

[0161] In a preferred embodiment, the cleaning mechanism further includes a cleaning shaft 45, a main support plate 46, a first guide plate 49, a second guide plate 48, and a positioning sleeve 44 fixed on the second bracket 26. The cleaning shaft 45 is rotatably coupled to the second bracket 26. The main support plate 46 is fixedly sleeved on the cleaning shaft 45. The first guide plate 49, the second guide plate 48, and the cleaning turntable 47 are distributed sequentially from top to bottom and are respectively fixedly connected to the main support plate 46. The cleaning shaft 45, the first guide plate 49, the second guide plate 48, the cleaning turntable 47, the support plate, and the positioning sleeve 44 are coaxial. The first guide plate 49, the second guide plate 48, the cleaning turntable 47, and the support plate are all annular.

[0162] The top surface of the positioning sleeve 44 is divided into a rising area 66 and a falling area 67 along the circumference. The rising area 66 is higher than the falling area 67, and the rising area 66 and the falling area 67 are smoothly connected. The function of the positioning sleeve 44 is to enable each cleaning module to rise and fall regularly when rotating.

[0163] In the optional embodiments of this example, the cleaning module preferably includes a cleaning support column 50, a connecting plate 53, a fixing plate 54, a floating plate 55, a docking block 56, an air blowing needle 60, and a filter.

[0164] The cleaning support column 50 passes through the first guide plate 49 and slides with the first guide plate 49. A third roller 51 is installed at the bottom end of the cleaning support column 50. The third roller 51 is used to roll with the top surface of the positioning sleeve 44.

The bottom end of the lifting sleeve 57 is fixedly connected to the floating plate 55.

[0167] The docking block 56 is fixed on the floating plate 55. A cavity is provided inside the docking block 56. The bottom end of the docking block 56 is provided with a docking interface 62 for docking with the bottle mouth of the bottle. The side wall of the docking block 56 is provided with a dust outlet 61. The docking interface 62 and the dust outlet 61 are respectively connected to the cavity. Several guide posts are also fixed below the floating plate 55. The guide posts pass through the second guide plate 48 and slide with the second guide plate 48. The shape and size of the docking interface 62 match the shape and size of the bottle mouth of the bottle to be cleaned, so that the docking interface 62 can fit with the bottle mouth of the bottle to be cleaned, ensuring the airtightness between the docking block 56 and the bottle mouth when docking.

[0168] The air-blowing needle 60 is fixedly connected to the fixing plate 54. The top end of the air-blowing needle 60 is connected to the air source through a pipe. The air-blowing needle 60 passes through the docking block 56, and the bottom end of the air-blowing needle 60 is located directly below the docking interface 62.

[0169] It should be noted that since each cleaning module rotates with the cleaning mechanism during operation, an air slip ring is also provided on the cleaning shaft 45 to prevent the connecting pipes between the air needle 60 and the air source from getting tangled. Each air needle 60 is connected to the air slip ring through a pipe, and the air slip ring is connected to the air source. The air slip ring is a commercially available product well known in the art.

[0170] In this embodiment, a filter can also be provided at the top of the air-blowing needle 60. The top of the air-blowing needle 60 is connected to the air outlet of the filter, and the air inlet of the filter is connected to the aforementioned air slip ring through a pipeline. In addition, each floating mechanism also includes a protective sleeve 59, which is sleeved on the outside of the spring 58, and the top of the protective sleeve 59 is engaged with the fixing plate 54. The function of the protective sleeve 59 is to prevent foreign objects from entering the spring 58 and affecting the normal operation of the spring 58.

The cap-grabbing hook 129 includes a support plate 801 and a hook rod fixed on the support plate 801.

[0207] When the cap-removing bracket 128 rotates relative to the capping turntable, the top of the hook rod can move to the cap-removing opening and abut against the inner wall of the bottle cap directly above the cap-removing opening, causing the bottle cap directly above the cap-removing opening to overcome the elastic force of the torsion spring and leave the cap-dispensing groove 124, so as to hook the bottle cap directly above the cap-removing opening onto the cap-grabbing hook 129.

[0208] In this embodiment, the third drive mechanism 126 is fixed on the second guide turntable. The third drive mechanism 126 includes a linear motor, a slide groove, and a rack.

A sealing element 144 is provided inside the cap head 141. The sealing element 144 isolates the annular gap 146 from the central opening of the silicone ring. A vent hole 143 is provided on the connecting post 142, which connects the annular gap 146 to the connecting tube 140.

[0211] In the optional embodiments of this example, the second drive mechanism preferably includes a central rotating shaft, a capping turntable, a second guide turntable, and a capping positioning cylinder 130, which are coaxially arranged. The central rotating shaft is vertical and rotates with the frame of the capping assembly. The capping positioning cylinder 130 is fixedly connected to the frame of the capping assembly.

The slider 137 slides in cooperation with the vertical slide rail; the cap clamping mechanism slides in cooperation with the second guide turntable in the vertical direction.

[0214] In the optional schemes of this embodiment, it is more preferred that the second bottle clamping mechanism is evenly distributed on the capping turntable along the circumference; the cap taking bracket 128 is rotatably engaged with the second guide turntable.

[0215] In the optional solutions of this embodiment, it is more preferred that the central rotating shaft and the hollow rotating shaft are connected by a transmission.

[0216] In the optional solutions of this embodiment, it is more preferred that both the first bottle clamping mechanism 117 and the second bottle clamping mechanism adopt finger cylinders.

[0217] The working principle of the pharmaceutical bottle filling production line 10000 in this embodiment is as follows:

[0218] Step 1: Bottle handling process:

[0219] First, the medicine bottle 603 is poured into the bottle storage hopper 1. The bottle storage hopper 1 serves as the starting point of the entire bottle sorting process and is responsible for storing a large amount of bottles to be sorted. The bottle conveyor belt 2 orderly delivers the medicine bottles 603 in the bottle storage hopper 1 to the bottle feeding chute 3. The inclined bottle feeding chute 3 ensures that the medicine bottles 603 can smoothly slide to the higher end of the bottle separating cone plate 10, achieving initial orientation and conveying. The axial inclined design of the bottle separating cone plate 10, combined with the self-rotation drive of the bottle sorting and sorting drive motor 21, causes the medicine bottles 603 to roll down the inclined surface of the bottle separating cone plate 10 under the combined action of gravity and rotational force, and enter the bottle sorting ring belt 6.

[0220] Simultaneously, the bottle-scraping drive mechanism drives the bottle-scraping ring 6 to rotate; the bottle-scraping ring 6 surrounds the bottle-separating cone plate 10, with its inner edge fitting against the outer edge of the bottle-separating cone plate 10, ensuring that the pharmaceutical bottle 603 can smoothly transition to the bottle-scraping ring 6. The radial through groove 601 on the top surface of the bottle-scraping ring 6 and the vertical through groove 602 on the outer edge, in conjunction with the drive of the bottle-scraping drive mechanism, realize the transformation of the pharmaceutical bottle 603 from an inclined state to an upright state;

[0221] The design of the pallet 801 and the discharge guide trough 803 ensures that the pharmaceutical bottle 603 smoothly transitions from the bottle handling ring belt 6 to the discharge conveyor belt 802. The guide trough prevents the bottle from shifting or tipping over during the discharge process, ensuring the continuity and accuracy of the discharge.

[0222] Step 2, Airflow Cleaning Process:

[0223] Since the bottle conveyor belt in the airflow cleaning machine 2000 is connected to the discharge conveyor belt 802 in the bottle unscrambler, the pharmaceutical bottles 603 after unscrambling will be conveyed from the discharge conveyor belt 802 to the bottle conveyor belt. Under the action of the conveyor belt and the rotation of the bottle screw 27, the bottles to be cleaned move towards the discharge end of the bottle conveyor belt. It is worth noting that during this process, the screw 27 engages with the bottle to be cleaned through its threaded groove and drives the bottle forward along the bottle conveyor belt. The pitch on 7 can control the distance between two adjacent bottles on the bottle conveyor belt. When the bottle to be cleaned is conveyed to the discharge end of the bottle conveyor belt, a first slot on the first screw-in turntable 28 also rotates to the discharge end of the bottle conveyor belt, and the first slot moves towards the bottle at the discharge end, so that the bottle to be cleaned is stuck in the first slot. Then the first screw-in turntable 28 drives the bottle to rotate. When the bottle to be cleaned rotates with the first screw-in turntable 28 to the connection point with the cleaning turntable 47, it is stuck from the first slot into the second slot.

[0224] Then, driven by the cleaning shaft 45, the third roller 51 in the cleaning module above the second slot of the bottle to be cleaned will roll from the rising area 66 on the positioning sleeve 44 into the falling area 67, causing the overall height of the cleaning module to decrease. This allows the docking block 56 to dock with the bottle opening in the second slot. During docking, the spring 58 ensures that the mating interface 62 at the bottom of the docking block 56 fits tightly with the bottle opening, guaranteeing a seal between the mating interface 62 at the bottom of the docking block 56 and the bottle opening. The air needle 60 extends into the bottle, and compressed air is blown into the internal space of the bottle. Foreign objects (i.e., dust and other debris) are blown out of the bottle by compressed air and enter the dust collection tank 30 through the cavity, dust outlet 61, and dust inlet 63 in the docking block 56. Finally, they are sucked away by the first negative pressure device through the dust collection sleeve 65. The first negative pressure device is a vacuum cleaner. The dust is finally collected in the first negative pressure device. Before the bottle body rotates with the cleaning turntable 47 to the point of connection with the first rotating turntable 31, the third roller 51 in the cleaning module directly above the bottle body will roll from the landing area 67 on the positioning sleeve 44 into the lifting area 66, so that the overall height of the cleaning module rises, thereby causing the docking block 56 to separate from the bottle mouth of the bottle body on the second slot, and the blowing needle 60 also leaves the bottle body.

[0225] Then, when the bottle body rotates with the cleaning turntable 47 to the point of connection with the first rotating turntable 31, the bottle body is inserted from the second slot into the third slot. When the bottle body rotates with the first rotating turntable 31 to the feeding end of the bottle conveyor belt, the bottle body enters the bottle conveyor belt from the third slot under the action of the bottle discharge screw 33, and is sent out under the action of the bottle conveyor belt and the bottle discharge screw 33.

[0226] Step 3: Tracking the filling process:

[0227] (1) First, note that the filling machine 3000 should be turned on in advance, that is, the drive device of the first conveyor belt 70 and the first drive device for driving the screw 69 to rotate are turned on, and the medicine bottle 603 is transferred from the previous process, and the moving filling module is moved to the initial station to wait. At the initial station, the filling needle 90 is located directly above the medicine bottle 603 on the first conveyor belt 70.

[0228] (2) Formal operation:

[0229] 1) After airflow cleaning, the medicine bottle 603 is fed from the bottle conveyor belt into the first conveyor belt 70. There are six medicine bottles 603 on the first conveyor belt 70. When the medicine bottle 603 is directly below the infusion needle 90, the left and right drive mechanism drives the translation frame 72 to move the infusion needle 90 and the medicine bottle 603 synchronously. At the same time, the second front and rear drive device drives the clamping mounting frame 84 to move a set distance toward the first conveyor belt 70, and then controls the pneumatic gripper 102 to clamp the corresponding medicine bottle 603. At the same time, the lifting drive mechanism drives the lifting frame 88 to descend, so that the infusion needle 90 extends into the corresponding medicine bottle 603. Then the infusion pump 103 is turned on, and the infusion is in the infusion chamber. The filling process is completed during the synchronous movement of the injection needle 90 and the medicine bottle 603. After the filling pump 103 is turned on for a set time, the filling is completed. At this time, the filling pump 103 is turned off, and the lifting frame 88 is driven to rise by the lifting drive mechanism, so that the injection needle 90 leaves the corresponding medicine bottle 603. At the same time, the pneumatic gripper 102 is controlled to stop clamping the corresponding medicine bottle 603. The clamping device is driven by the second front and rear drive device to move the clamping device a set distance away from the first conveyor belt 70. Then, the translation frame 72 is driven by the left and right drive mechanism to move the injection needle 90 to the initial position to wait for the arrival of the next batch of medicine bottles 603. Then, the above process is repeated to fill the next batch of medicine bottles 603.

[0230] 2) After prolonged use, such as after 10,000 infusions, the infusion needle 90 needs to be disinfected. The disinfection process is as follows: First, the telescopic cylinder 96 is activated to drive the second rotating shaft 99 to rotate. The second rotating shaft 99 drives the first rotating shaft to rotate, causing the pressure plate 95 to rotate upward, providing clearance space for the infusion needle 90 to be inserted into the disinfection chamber 92. Then, the first front and rear drive device 87 drives the infusion mounting plate 89 to slide until the infusion needle 90 is directly above the corresponding disinfection chamber 92. Then, the lifting drive mechanism drives the lifting frame 88 to descend, allowing the infusion needle 90 to extend into the corresponding disinfection chamber 92. Then, the telescopic cylinder 96 is activated to drive the second rotating shaft 99 to rotate. The second rotating shaft 99 drives the first rotating shaft to rotate, causing the pressure plate 95 to rotate downward, pressing the top of the infusion needle 90.

[0231] Then, the liquid pump is turned on to inject disinfectant into the disinfection containers, i.e., each disinfection chamber 92, to disinfect the infusion needle 90. The disinfectant is then returned to the waste liquid collection tank through the return pipe. After disinfection, the telescopic cylinder 96 is turned on to drive the second rotating shaft 99 to rotate. The second rotating shaft 99 drives the first rotating shaft to rotate, causing the pressure needle plate 95 to rotate upward, providing clearance for the infusion needle 90 to exit. Then, the lifting frame 88 is driven to rise through the lifting drive mechanism, causing the infusion needle 90 to leave the corresponding disinfection chamber 92. Then, the infusion mounting plate 89 is driven to slide through the first front and rear drive device 87, causing the infusion needle 90 to return to the initial position. The residual sewage in the disinfection chamber 92 can be discharged through the drain pipe 94.

[0233] (1) Working process of the insert unit

[0234] ① Feeding and conveying:

[0235] The second conveyor belt 127 in the feeding and conveying assembly is activated. After the filled pharmaceutical bottles 603 are conveyed onto the second conveyor belt 127, the second conveyor belt 127 moves the pharmaceutical bottles 603. At the same time, the bottle conveying screw 104 and the bottle baffle 105 are arranged parallel to each other and spaced apart above the second conveyor belt 127. The pharmaceutical bottles 603 are clamped between the threaded groove of the bottle conveying screw 104 and the bottle baffle 105. The rotation of the bottle conveying screw 104 drives the pharmaceutical bottles 603 to move stably along the conveying direction of the second conveyor belt 127, conveying the pharmaceutical bottles 603 to the second screw-in turntable 106.

[0236] ②Second screw-in turntable 106-cartridge bottle:

[0237] The second rotating turntable 106 has multiple fourth slots arranged circumferentially around its edge to engage the medicine bottle 603, causing the medicine bottle 603 to rotate.

[0238] ③ Supply turntable 108 supply:

[0239] The stopper feed turntable 108 rotates the stopper 132 to be directly below the stopper take-up mechanism 111, providing the stopper 132 to the stopper take-up mechanism 111.

[0240] ④ Cutting in line:

[0241] The first bottle clamping mechanism 117 operates, clamping the medicine bottle 603 at the connection between the second screw-in turntable 106 and the stopper assembly. At this time, the stopper removal mechanism 111 is positioned above the corresponding first bottle clamping mechanism 117.

[0242] The first drive mechanism drives the stopper-removing mechanism 111 to rise and fall. Specifically, the first drive mechanism includes a hollow rotating shaft, a first guide turntable 110, a stopper-filling turntable 109, a stopper-filling positioning cylinder 125, and a second drive device. The hollow rotating shaft is vertical and rotates in conjunction with the frame of the stopper-filling assembly. The second drive device drives the hollow rotating shaft to rotate, thereby causing the first guide turntable 110 and the stopper-filling turntable 109, which are fixedly connected to the hollow rotating shaft, to rotate. The first bottle-clamping mechanism 117 is circumferentially arranged on the stopper-filling turntable 109.

[0243] The plug-removing mechanism 111 includes a plug-suction head 112, a first vertical connecting rod 113, a first horizontal connecting rod 114, and a vertical first guide rod 115. The first guide rod 115 passes through the first guide turntable 110 and slides in engagement with the first guide turntable 110. The fifth roller 116 at the bottom end of the first guide rod 115 rolls in engagement with the top end of the plug-adding positioning cylinder 125.

[0244] The suction head 112 is connected to the hollow part of the hollow rotating shaft through a pipeline. One end of the hollow part of the hollow rotating shaft is connected to the air intake of the second negative pressure device through a rotary joint. When the stopper taking mechanism 111 descends above the stopper supply turntable 108, the suction head 112 uses negative pressure to suck up the bottle stopper 132 on the stopper supply turntable 108.

[0245] The top of the stopper positioning cylinder 125 is provided with a first protruding section and a first recessed section. When the fifth roller 116 rolls on the stopper positioning cylinder 125, it drives the stopper taking mechanism 111 to rise and fall. When the stopper taking mechanism 111 descends, it inserts the sucked stopper 132 into the mouth of the medicine bottle 603 held by the corresponding first bottle clamping mechanism 117. Then, the negative pressure of the stopper taking mechanism 111 is cut off, thus completing the stoppering operation.

[0246] ⑤ Transition turntable 118 delivers the bottle:

[0247] Multiple fifth slots arranged circumferentially on the edge of the transition turntable 118 engage with the stoppered medical bottle 603, and deliver the medical bottle 603 at the junction of the stopper assembly and the transition turntable 118, ready to enter the capping unit.

[0248] (2) Working process of the capping unit

[0249] ① Bottle cap feeding:

[0250] The bottle cap feeding assembly operates. A cap storage hopper 120 stores bottle caps, and a cap dispensing conveyor belt 121 transports the bottle caps from the storage hopper 120 to the bottle cap vibrating plate 123. A cap dispensing chute 124 is inclined, with one end connected to the discharge port of the bottle cap vibrating plate 123 and the other end equipped with a cap-blocking assembly. The cap-blocking assembly includes two opposing cap-blocking rods 131, L-shaped and rotatably connected to the cap dispensing chute 124, and connected to the chute 124 via a torsion spring. Under the elastic force of the torsion spring, the cap-blocking rods 131 can abut against the end of the cap dispensing chute 124 away from the bottle cap vibrating plate 123. The bottom end of the cap dispensing chute 124 away from the bottle cap vibrating plate 123 also has a cap-retrieving notch, and the bottom opening of the bottle cap abutting against the cap-blocking rod 131 communicates with the cap-retrieving notch.

[0251] ② Removing the cap:

[0252] The cap-removing mechanism is in operation. The cap-removing mechanism includes a third drive mechanism 126, a cap-removing bracket 128, and a cap-grabbing hook 129.

The cap-grabbing hook 129 is fixedly connected to the cap-removing bracket 128, and the cap-grabbing hook 129 includes a support plate 801 and a hook rod fixed on the support plate 801.

[0253] When the second guide turntable rotates with the central shaft, the cap-retrieving bracket 128 rotates with the second guide turntable. When the top of the hook passes the cap-retrieving opening, it abuts against the inner wall of the bottle cap directly above the opening, causing the bottle cap directly above the opening to overcome the spring force of the torsion spring and leave the cap-dispensing groove 124, thus hooking the bottle cap directly above the opening onto the cap-gripping hook 129. Then, the third drive mechanism 126 drives the cap-retrieving bracket 128 to rotate relative to the second guide turntable until the cap-gripping hook 129 and the bottle cap on the hook 129 are directly below the corresponding cap-gripping mechanism. After the cap-gripping mechanism removes the bottle cap from the hook 129, the third drive mechanism 126 drives the cap-retrieving bracket 128 to rotate in the opposite direction relative to the second guide turntable, so that the cap-retrieving bracket 128 rotates back to its original position to prepare for the next cap-retrieving operation.

[0254] ③Preparation of the cap-clamping mechanism:

[0255] Each cap clamping mechanism includes a mounting bracket 135, a servo drive motor 136, a connecting shaft 139, and a cap clamping assembly. The servo drive motor 136 is fixedly connected to the mounting bracket 135, and the top end of the connecting shaft 139 is fixedly connected to the output shaft of the servo drive motor 136.

[0256] The cap assembly includes a cap head 141, a cap silicone ring 145, and a connecting tube 140. The top end of the cap head 141 is connected to the bottom end of a connecting shaft 139 via the connecting tube 140. The bottom of the connecting shaft 139 is hollow, and a connection port is provided on its side wall. The connection port is connected to a positive pressure air source via a pipeline. The bottom end of the cap head 141 is provided with a cap silicone ring 145, and an annular gap 146 is formed between the top outer wall of the cap silicone ring 145 and the inner wall of the cap head 141. The top end of the cap head 141 is provided with a connecting post 142. A sealing element 144 is provided inside the cap head 141. The sealing element 144 isolates the annular gap 146 from the central opening of the silicone ring. The connecting post 142 is provided with a vent hole 143, which connects the annular gap 146 to the connecting tube 140.

[0257] ④ The second bottle-clamping mechanism clamps the bottle:

[0258] The second bottle clamping mechanism clamps the pharmaceutical bottle 603 at the junction of the transition turntable 118 and the capping assembly. The second bottle clamping mechanism is evenly distributed on the capping turntable along the circumference.

[0259] ⑤ Capping operation:

[0260] The second drive mechanism operates. The second drive mechanism includes a central rotating shaft, a capping turntable, a second guide turntable, and a capping positioning cylinder 130, all coaxially arranged. The central rotating shaft is vertical and rotatably engages with the frame of the capping assembly. The capping positioning cylinder 130 is fixedly connected to the frame of the capping assembly. The capping turntable and the second guide turntable are respectively fixedly connected to the central rotating shaft.

[0261] The top surface of the cap-screwing positioning cylinder 130 is sequentially provided with a first protruding section, a first recessed section, a second protruding section, and a second recessed section along the circumferential direction. The sixth roller 138 on the inner side of the mounting frame 135 rolls in cooperation with the top surface of the cap-screwing positioning cylinder 130, driving the cap-clamping mechanism to rise and fall. At the same time, the slider 137 on the mounting frame 135 slides in cooperation with the vertical slide rail on the second guide turntable, so that the cap-clamping mechanism slides in cooperation with the second guide turntable in the vertical direction.

[0262] The cap-retrieving mechanism moves the hooked cap directly below the corresponding cap-clamping mechanism. Positive pressure is introduced into the cap-clamping assembly of the cap-clamping mechanism, causing the cap-clamping silicone ring 145 to deform under the positive pressure, clamping the cap on the cap-grabbing hook 129 of the cap-retrieving mechanism. After the cap-retrieving mechanism moves away, the height of the cap-clamping mechanism decreases, and the clamped cap is tightened onto the mouth of the pharmaceutical bottle 603 held by the corresponding second bottle-clamping mechanism. Specifically, the servo drive motor 136 drives the connecting shaft 139 to rotate, which in turn drives the cap-clamping head 141 to rotate, tightening the cap.

[0263] ⑥ The second rotating turntable 119 delivers the bottle:

[0264] Multiple sixth slots arranged circumferentially on the edge of the second rotating turntable 119 engage with the capped medicine bottle 603, thus delivering the medicine bottle 603 at the junction of the capping assembly and the second rotating turntable 119.
