Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically, to a scratch-resistant conveying device for bottles of oral liquid preparations of traditional Chinese medicine. Background Technology

[0002] In the production of oral liquid preparations of traditional Chinese medicine, the integrity and cleanliness of the bottle directly affect the quality and safety of the medicine. As a carrier for directly administered oral medication, scratches, abrasions, or even breakage of the bottle not only affect the consistency of the product's appearance but may also damage the structural integrity of the bottle, leading to contamination or even leakage of the liquid during subsequent storage or transportation, thus posing potential risks to patients' health. However, in the current production process of oral liquid preparations of traditional Chinese medicine, the transfer process, as the core link connecting key processes such as filling, sterilization, and packaging, has long faced numerous technical bottlenecks.

[0003] Existing conveying devices mostly rely on traditional conveyor belts for direct transport or simple mechanical clamps for fixed transport. When using conveyor belts for direct transport, the bottles lack a stable positioning structure. During high-speed transport or when the conveyor belt starts and stops, the bottles are prone to collisions and friction with the conveyor belt surface, adjacent bottles, or the side walls of the device, resulting in scratches, abrasions, and other abrasion problems. For devices using simple mechanical clamps for fixing, the hard contact between the clamps and the bottles can also easily cause scratches, especially for thin oral liquid bottles, which may even directly lead to bottle breakage, increasing production losses. At the same time, the transport stability of existing devices is generally insufficient. During transport, the bottles are prone to tipping or shifting due to factors such as conveyor belt deviation, loose clamps, or external vibrations. This not only requires frequent manual intervention and adjustment, seriously affecting production efficiency, but may also cause liquid spillage due to bottle tipping, resulting in raw material waste, while also polluting the production environment and increasing cleaning costs.

[0004] Furthermore, existing transfer devices have a low level of automation. When transferring bottles from the transfer stage to the packaging station, manual assistance is often required for positioning and transfer operations. This manual intervention not only increases labor costs but also easily leads to bottle damage or transfer delays due to operational errors, making it difficult to meet the demands of large-scale, high-efficiency production of modern Chinese medicine oral liquid preparations. With the continuous development of the Chinese medicine industry, the market's requirements for the quantity and quality of oral liquid preparations are increasing. The shortcomings of existing transfer devices in terms of scratch resistance, transfer stability, and automation have become key factors restricting the improvement of production quality and efficiency. Developing a transfer device that can achieve scratch-free, stable, and highly automated bottle transfer has become an urgent technical need to be addressed in the industry. Summary of the Invention

[0005] The purpose of this invention is to provide a scratch-resistant transport device for oral liquid preparations of traditional Chinese medicine to solve the above-mentioned problems.

[0006] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:

[0007] A scratch-resistant conveying device for traditional Chinese medicine oral liquid preparation bottles includes a conveyor belt assembly, multiple standing conveyor assemblies, a pair of triggering assemblies, a transfer assembly, and a pair of photoelectric displacement sensors. The conveyor belt assembly is used to transport traditional Chinese medicine oral liquid preparation bottles in a straight line. The multiple standing conveyor assemblies are evenly installed on the conveyor belt assembly to lock the traditional Chinese medicine oral liquid preparation bottles. The pair of triggering assemblies are symmetrically installed at the tail end of the conveyor belt assembly to unlock the traditional Chinese medicine oral liquid preparation bottles. The transfer assembly is fixedly installed at the tail end of the conveyor belt assembly to transfer the traditional Chinese medicine oral liquid preparation bottles to the next station. The pair of photoelectric displacement sensors are symmetrically installed on the conveyor belt assembly in the area adjacent to the triggering assemblies to detect the real-time position of the standing conveyor assemblies.

[0008] As a further improvement of the present invention, the conveyor belt assembly includes a frame, with a drive pulley and a driven pulley rotatably mounted at both ends of the frame, and a conveyor belt mounted on both the drive pulley and the driven pulley. A drive motor and a reducer are fixedly mounted at the first end of the frame. The output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the drive pulley. After being decelerated by the reducer, the drive motor drives the drive pulley to rotate, thereby using the conveyor belt to linearly transport the traditional Chinese medicine oral liquid preparation bottles on the standing conveyor assembly.

[0009] As a further improvement of the present invention, multiple support frames are fixedly installed on the frame along the conveying direction of the conveyor belt, and support pulleys are rotatably installed on the support frames. Baffles are symmetrically fixedly installed on the frame along the conveying direction of the conveyor belt. The support pulleys can support the conveyor belt, making long-distance transmission more stable.

[0010] As a further improvement of the present invention, the standing transmission assembly includes a transmission base fixedly installed on the outer surface of the conveyor belt. The center of the transmission base is provided with a standing hole that matches the oral liquid preparation bottle of traditional Chinese medicine. Multiple evenly distributed annular airbags are fixedly connected to the inner wall of the standing hole. A flexible anti-tilting plate is fixedly connected to the upper end of the standing hole away from the transmission direction. Repulsive magnets are embedded in both the left and right ends of the transmission base. The oral liquid preparation bottle of traditional Chinese medicine can be directly placed in the standing hole to achieve stable transmission. Compared with other transmission methods, it is more stable and reliable, less prone to scratches, and can be flexibly protected by the annular airbags. The flexible anti-tilting plate can prevent the oral liquid preparation bottle of traditional Chinese medicine from tilting to the side away from the transmission direction of the conveyor belt after it is lifted.

[0011] As a further improvement of the present invention, the left and right ends of the transmission base are provided with strip grooves, and a hydraulic actuator is installed inside the strip groove. The hydraulic actuator is used to drive the lifting action of the oral liquid preparation bottle of traditional Chinese medicine in the standing hole, so as to facilitate the transfer component to transfer it to the next packaging process.

[0012] As a further improvement of the present invention, the hydraulic actuator includes a strip-shaped pressure plate slidably mounted inside the strip-shaped groove. A pressure rod is fixedly connected to the inner end of the strip-shaped pressure plate. A return spring is fixedly connected between the strip-shaped pressure plate and the inner wall of the strip-shaped groove. A U-shaped hydraulic oil passage communicating with a pair of strip-shaped grooves is opened on the inner side of the transmission base. The U-shaped hydraulic oil passage extends upward to form an upward flow passage communicating with a standing hole. An interference-fit piston is slidably mounted at the opening of the U-shaped hydraulic oil passage, and the piston is fixedly connected to the pressure rod. A piston with an interference fit is slidably installed inside the flow channel. A push rod is fixedly connected to the upper end of the piston. A lifting platform is fixedly connected to the upper end of the push rod. When the strip pressure plate is subjected to pressure, it will move inward against the elastic force of the return spring, thereby pushing the piston to move inward through the pressure rod to squeeze the hydraulic oil in the U-shaped hydraulic oil flow channel. Under the pressure relationship, the piston in the rising flow channel will move upward, thereby pushing the traditional Chinese medicine oral liquid preparation bottle on the lifting platform to lift it, and after leaving the standing hole, it can be easily transferred by the transfer component.

[0013] As a further improvement of the present invention, the triggering component includes a mounting plate fixedly mounted on the frame. An electric push rod is fixedly mounted on the outer end of the mounting plate. A trigger rod is fixedly connected to the output end of the electric push rod, and the trigger rod corresponds to the position of the strip groove. A straightening lip is fixedly mounted on the trigger rod via a bracket, and the straightening lip is located on the upper side of the trigger rod. A drag-reducing ball is movably mounted on the end of the trigger rod away from the electric push rod. The electric push rod can extend to drive the trigger rod to move inward to squeeze the strip pressure plate, triggering the lifting action of the traditional Chinese medicine oral liquid preparation bottle. Since the conveyor belt is constantly running, the transmission base is constantly in a moving state, and the design of the strip groove... The trigger rod can easily maintain a constant moving and pressing state on the strip pressure plate. The drag-reducing ball can reduce the frictional resistance between the trigger rod and the strip pressure plate, ensuring that the lifting action of the oral liquid medicine preparation bottle can be smoothly triggered. In addition, when the trigger rod moves inward to press the strip pressure plate, the corrective lip moves synchronously with the bracket to gradually approach the oral liquid medicine preparation bottle. During the approaching process, it can actively correct the posture of the oral liquid medicine preparation bottle, preventing the oral liquid medicine preparation bottle from tilting during the transfer process. Finally, it forms a guide rail-like system to guide the movement of the oral liquid medicine preparation bottle, ensuring that it can accurately cooperate with the transfer component to complete the transfer.

[0014] As a further improvement of the present invention, the corrective lip includes a hollow lip. Multiple evenly distributed telescopic holes are provided at the end of the hollow lip away from the mounting plate. Matching flexible anti-tilting blocks are slidably installed within the telescopic holes. A return spring is fixedly connected between the flexible anti-tilting blocks and the inner wall of the hollow lip. A base plate is fixedly installed on the inner side of the hollow lip. Multiple T-shaped slide rails corresponding to the flexible anti-tilting blocks are fixedly installed at the upper end of the base plate. Matching magnetic sliders are slidably installed on the T-shaped slide rails. A connecting rod is fixedly connected between the magnetic sliders and the flexible anti-tilting blocks. When the oral liquid preparation bottle is lifted by the hydraulic actuator and is in an unstable transmission state, the flexible anti-tilting plate can prevent it from tilting away from the transfer assembly. While there is a risk of tipping over, there is still a risk of tipping over on the side closest to the transfer component. In this case, a flexible anti-tilting block is used to block it and prevent it from tipping over. When the Chinese herbal oral liquid preparation bottle needs to pass through the flexible anti-tilting block, the repulsive magnet will first use the magnetic field to repel the magnetic slider to move inward, thereby driving the flexible anti-tilting block to move inward simultaneously to avoid the bottle, so as to facilitate the passage of the Chinese herbal oral liquid preparation bottle and avoid squeezing and scratching. After the transfer base passes, it will be reset under the elastic force of the reset spring two. During the movement before contacting the transfer component, multiple flexible anti-tilting blocks will provide anti-tilting protection in sequence. The flexible anti-tilting blocks will also avoid the bottle in sequence under the indirect action of the repulsive magnet until they contact the transfer component for transfer.

[0015] As a further improvement of the present invention, the transfer assembly includes an extension frame fixedly installed at the tail end of the frame. A packaging station is fixedly installed at the upper end of the extension frame. A positioning stage is fixedly installed at one end of the packaging station near the frame. A second drive motor is fixedly installed at the lower end of the positioning stage. A rotating transfer arm is fixedly installed at the output end of the second drive motor. The traditional Chinese medicine oral liquid preparation bottle is adsorbed and fixed by the rotating transfer arm, and then driven by the second drive motor to rotate to the packaging station for the packaging process.

[0016] As a further improvement of the present invention, the rotary transfer arm includes a rotating column connected to the output end of the second drive motor. An extension arm is fixedly installed on the outer wall of the rotating column, and a hollow adsorption half-sleeve is fixedly installed at the outer end of the extension arm. A pressure sensor is embedded in the center of the hollow adsorption half-sleeve, and multiple evenly distributed adsorption holes are also opened on the outer surface of the hollow adsorption half-sleeve. A top plate is fixedly installed at the upper end of the rotating column, and a negative pressure air pump is fixedly installed at the upper end of the top plate. The negative pressure air pump is connected to the hollow adsorption half-sleeve through a pipe. After the traditional Chinese medicine oral liquid preparation bottle is lifted and guided by the trigger component, the traditional Chinese medicine oral liquid preparation bottle can smoothly contact the hollow adsorption half-sleeve. After the pressure sensor senses the pressure, the negative pressure air pump is immediately started to form a negative pressure state. Then, the traditional Chinese medicine oral liquid preparation bottle is adsorbed and fixed through the adsorption holes. Then, the second drive motor is started to drive it to rotate to one side of the packaging station.

[0017] Compared with the prior art, the advantages of this invention are:

[0018] (1) Existing traditional Chinese medicine oral liquid preparation transfer devices mostly use direct conveyor belt transfer or simple clamp fixation transfer, which easily leads to hard contact between the bottle and the conveyor belt and clamp, resulting in bottle scratches. This device uses an annular airbag in the standing transfer component to flexibly wrap the bottle, and with flexible anti-tilt plate, flexible anti-forward block and other flexible components, it avoids hard contact between the bottle and other components from multiple angles, greatly reducing the risk of bottle scratches; at the same time, the transfer component adopts hollow adsorption half-set adsorption transfer, avoiding the squeezing and scratching of the bottle during mechanical clamping transfer, further improving the anti-scratch effect.

[0019] (2) In existing conveying devices, bottles are prone to tipping and deviation during transport, affecting conveying efficiency and the normal operation of subsequent processes. This device positions the bottle through a standing hole, and the inflated annular airbag fits tightly against the bottle body to ensure that the bottle does not shake during transport. The combination of flexible anti-tilting plates and corrective lip plates effectively prevents the bottle from tipping and deviating. The synergistic effect of photoelectric displacement sensors and PLC control systems achieves precise synchronization of the actions of each component, further improving the stability of the transport. In addition, the design of the support frame and support pulleys avoids sagging and shaking of the conveyor belt during long-distance transport, providing a guarantee for the stable transport of the standing conveying components.

[0020] (3) Existing conveyor devices are mostly designed for specific sizes of oral liquid preparation bottles of traditional Chinese medicine. When the bottle size changes, it is necessary to replace components such as the conveyor belt and clamps, which has poor adaptability. The annular airbag in this device can adapt to bottles of different diameters by adjusting the inflation volume. The flexible anti-tilting plate and flexible anti-forward blocking block have a certain elastic extension range and can also adapt to the anti-tipping requirements of bottles of different sizes. At the same time, the transmission speed, trigger position and other parameters can be easily adjusted through the PLC control system, which further improves the adaptability of the device to different production needs, eliminates the need for frequent replacement of parts and reduces equipment modification costs.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Please see Figures 1-4 A scratch-resistant conveying device for oral liquid Chinese medicine preparations includes a conveyor belt assembly 1, multiple standing conveyor assemblies 2, a pair of triggering assemblies 3, a transfer assembly 4, and a pair of photoelectric displacement sensors 5. The conveyor belt assembly 1 is used to transport oral liquid Chinese medicine preparations bottles in a straight line. The multiple standing conveyor assemblies 2 are evenly installed on the conveyor belt assembly 1 to lock the oral liquid Chinese medicine preparations bottles. The pair of triggering assemblies 3 are symmetrically installed at the tail end of the conveyor belt assembly 1 to unlock the oral liquid Chinese medicine preparations bottles. The transfer assembly 4 is fixedly installed at the tail end of the conveyor belt assembly 1 to transfer the oral liquid Chinese medicine preparations bottles to the next station. The pair of photoelectric displacement sensors 5 are symmetrically installed on the conveyor belt assembly 1 in the area adjacent to the triggering assemblies 3 to detect the real-time position of the standing conveyor assemblies 2.

[0036] A pair of photoelectric displacement sensors 5 are infrared type, powered by 24V DC, and fixed near the trigger component 3 of the conveyor belt component 1. They detect the position of the standing transmission component 2 in real time and transmit the signal to the main controller to coordinate the timing of the actions of each component.

[0037] The conveyor belt assembly 1 includes a frame 101. A drive pulley 102 and a driven pulley 103 are rotatably mounted at both ends of the frame 101. A conveyor belt 104 is mounted on both the drive pulley 102 and the driven pulley 103. A drive motor 105 and a reducer 106 are fixedly mounted at the beginning of the frame 101. The output end of the drive motor 105 is connected to the input end of the reducer 106. The output end of the reducer 106 is connected to the drive pulley 102. After being reduced by the reducer 106, the drive motor 105 drives the drive pulley 102 to rotate, thereby using the conveyor belt 104 to linearly transport the traditional Chinese medicine oral liquid preparation bottles on the standing conveyor assembly 2.

[0038] Multiple support frames 107 are fixedly installed on the frame 101 along the conveying direction of the conveyor belt 104. Support pulleys 108 are rotatably installed on the support frames 107. Baffles 109 are symmetrically fixedly installed on the frame 101 along the conveying direction of the conveyor belt 104. The support pulleys 108 can support the conveyor belt 104, making long-distance transmission more stable.

[0039] It should be noted that in conveyor belt assembly 1, the frame 101 is made of high-strength aluminum alloy, which ensures structural stability and has the advantage of lightweight design, and can withstand the load of conveyor belt 104 and standing transmission assembly 2 for a long time; the drive pulley 102 and driven pulley 103 are made of wear-resistant cast iron to extend their service life; the conveyor belt 104 is made of food-grade polyurethane, which meets the hygiene standards for the production of traditional Chinese medicine preparations, and has excellent flexibility and wear resistance, avoiding scratches when in contact with the bottle. The drive motor 105 is a three-phase asynchronous motor, powered by 380V three-phase AC power. The speed is adjusted by the main controller, and together with the reducer 106, the transmission speed of the conveyor belt 104 is precisely controlled to adapt to different production rhythms. The support frame 107 is made of stainless steel and is welded and fixed to the frame 101. The support pulley 108 at its upper end is also made of wear-resistant cast iron, which can reduce the sagging deformation of the conveyor belt 104 during long-distance transmission. The side baffles 109 are made of plastic and are fixed by bolts, which play a lateral limiting role for the standing transmission component 2 and prevent transmission deviation.

[0040] The standing conveyor assembly 2 includes a conveyor base 21 fixedly installed on the outer surface of the conveyor belt 104. The center of the conveyor base 21 has a standing hole 22 that matches the traditional Chinese medicine oral liquid preparation bottle. Multiple evenly distributed annular airbags 23 are fixedly connected to the inner wall of the standing hole 22. A flexible anti-tilting plate 24 is fixedly connected to the upper end of the standing hole 22 away from the conveying direction. Repulsive magnets 25 are embedded in both the left and right ends of the conveyor base 21. The traditional Chinese medicine oral liquid preparation bottle can be directly placed in the standing hole 22 to achieve stable transmission. Compared with other transmission methods, it is more stable and reliable, less prone to scratches, and can be flexibly protected by the annular airbags 23. The flexible anti-tilting plate 24 can prevent the traditional Chinese medicine oral liquid preparation bottle from tilting to the side away from the conveying direction of the conveyor belt 104 after it is lifted.

[0041] The transmission base 21 is injection molded from engineering plastic with a smooth, burr-free surface; the annular airbag 23 inside the standing hole 22 is made of medical-grade silicone, which elastically fits the outer wall of the bottle to achieve flexible locking, avoiding hard contact and scratching, and is also compatible with bottles of different diameters within a certain range; the flexible anti-tilting plate 24 is made of rubber and is fixed to the upper end of the standing hole 22 on the side away from the transmission direction, which can prevent the bottle from tipping over when it is lifted; the repulsive magnet 25 is a neodymium iron boron permanent magnet with stable magnetism.

[0042] The left and right ends of the transmission base 21 are also provided with strip grooves 26. A hydraulic actuator 27 is installed inside the strip groove 26. The hydraulic actuator 27 is used to drive the lifting action of the oral liquid preparation bottle of traditional Chinese medicine in the standing hole 22, so that the transfer component 4 can transfer it to the next packaging process.

[0043] The trigger assembly 3 includes a mounting plate 31 fixedly mounted on the frame 101. An electric push rod 32 is fixedly mounted on the outer end of the mounting plate 31. A trigger rod 33 is fixedly connected to the output end of the electric push rod 32, and the trigger rod 33 corresponds to the position of the strip groove 26. A straightening lip 34 is fixedly mounted on the trigger rod 33 via a bracket 35, and the straightening lip 34 is located on the upper side of the trigger rod 33. A drag-reducing ball bearing 36 is movably mounted on the end of the trigger rod 33 away from the electric push rod 32. The electric push rod 32 can extend to drive the trigger rod 33 to move inward to squeeze the strip pressure plate 271, triggering the lifting action of the traditional Chinese medicine oral liquid preparation bottle. Since the conveyor belt 104 is constantly running, the transmission base 21 is constantly in a moving state, while the strip groove 26... The design allows the trigger rod 33 to maintain a constant moving and pressing state on the strip pressure plate 271. The drag-reducing ball 36 can reduce the frictional resistance between the ball and the strip pressure plate 271, ensuring that the lifting action of the oral liquid preparation bottle can be smoothly triggered. In addition, when the trigger rod 33 moves inward to press the strip pressure plate 271, the bracket 35 drives the corrective lip 34 to move synchronously and gradually approach the oral liquid preparation bottle. During the approach process, it can actively correct the posture of the oral liquid preparation bottle, preventing the oral liquid preparation bottle from tilting during the transfer process. Finally, it forms a guide rail-like structure to guide the movement of the oral liquid preparation bottle, ensuring that it can accurately cooperate with the transfer component 4 to complete the transfer.

[0044] Mounting plate 31 is made of stainless steel and is fixed to frame 101 with bolts; electric push rod 32 is DC type, powered by 24V DC power, which is obtained by the power module converting AC power, and the main controller controls its extension and retraction according to the signal of photoelectric displacement sensor 5; trigger rod 33 is made of aluminum alloy, and the end friction-reducing ball 36 is a stainless steel ball with plastic coating, which converts sliding friction into rolling friction and reduces extrusion resistance.

[0045] The transfer assembly 4 includes an extension frame 41 fixedly installed at the tail end of the frame 101. A packaging station 42 is fixedly installed on the upper end of the extension frame 41. A positioning stage 43 is fixedly installed on the end of the packaging station 42 near the frame 101. A second drive motor 44 is fixedly installed on the lower end of the positioning stage 43. A rotating transfer arm 45 is fixedly installed on the output end of the second drive motor 44. The traditional Chinese medicine oral liquid preparation bottle is adsorbed and fixed by the rotating transfer arm 45, and then driven by the second drive motor 44 to rotate to the packaging station 42 for the packaging process.

[0046] The rotary transfer arm 45 includes a rotating column 451 connected to the output end of a drive motor 44. An extension arm 452 is fixedly installed on the outer wall of the rotating column 451. A hollow adsorption half-set 453 is fixedly installed at the outer end of the extension arm 452. A pressure sensor 454 is embedded in the center of the hollow adsorption half-set 453. Multiple evenly distributed adsorption holes 455 are also opened on the outer surface of the hollow adsorption half-set 453. A top plate 456 is fixedly installed at the upper end of the rotating column 451. A negative pressure air pump is fixedly installed at the upper end of the top plate 456. 457, the negative pressure air pump 457 is connected to the hollow adsorption half set 453 through the pipeline. After the trigger component 3 lifts and guides the Chinese medicine oral liquid preparation bottle, the Chinese medicine oral liquid preparation bottle can smoothly contact the hollow adsorption half set 453. After the pressure sensor 454 senses the pressure, the negative pressure air pump 457 is immediately started to form a negative pressure state. Then, the Chinese medicine oral liquid preparation bottle is adsorbed and fixed through the adsorption hole 455. Then, the drive motor 44 is started to drive it to rotate to the side of the packaging station 42.

[0047] The extension frame 41 is made of stainless steel and welded to the frame 101; the packaging station 42 is a metal frame with a food-grade plastic sheet on the surface, providing a stable working platform; the positioning table 43 is made of cast iron to ensure the stable operation of the second drive motor 44. The second drive motor 44 is a servo motor, powered by 220V AC, and its speed and angle are precisely controlled by the main controller; the rotating column 451 of the rotary transfer arm 45 is made of stainless steel, and the extension arm 452 is made of aluminum alloy; the hollow adsorption half-set 453 is made of plastic and covered with a silicone pad on the inside to fit the shape of the bottle; the pressure sensor 454 is a thin-film type, and the signal is transmitted to the main controller; the negative pressure air pump 457 is a DC type, powered by 24V DC. After the pressure sensor 454 detects the contact signal, the main controller starts the air pump to form negative pressure, which stably adsorbs the bottle through the adsorption hole 455.

[0048] Example 2:

[0049] The hydraulic actuator 27 includes a strip-shaped pressure plate 271 slidably mounted inside the strip-shaped groove 26. A pressure rod 272 is fixedly connected to the inner end of the strip-shaped pressure plate 271. A return spring 273 is fixedly connected between the strip-shaped pressure plate 271 and the inner wall of the strip-shaped groove 26. A U-shaped hydraulic oil passage 275 communicating with a pair of strip-shaped grooves 26 is opened inside the transmission base 21. The U-shaped hydraulic oil passage 275 extends upward to a rising passage 276 communicating with the standing hole 22. An interference-fit piston 274 is slidably mounted at the opening of the U-shaped hydraulic oil passage 275, and the piston 274 is fixedly connected to the pressure rod 272. A spring 273 is slidably mounted inside the rising passage 276. The piston 277 is an interference fit piston 277. The upper end of the piston 277 is fixedly connected to the push rod 278. The upper end of the push rod 278 is fixedly connected to the lifting platform 279. When the strip pressure plate 271 is subjected to pressure, it will move inward against the elastic force of the return spring 273. Then, the pressure rod 272 pushes the piston 274 to move inward to squeeze the hydraulic oil in the U-shaped hydraulic oil channel 275. Under the pressure relationship, the piston 277 in the rising channel 276 will move upward. Then, the push rod 278 pushes the traditional Chinese medicine oral liquid preparation bottle on the lifting platform 279 to lift it. After leaving the standing hole 22, it is convenient for the transfer component 4 to transfer it.

[0050] The strip pressure plate 271 and pressure rod 272 are made of stainless steel with polished surfaces to reduce friction; the return spring 273 is a stainless steel spring that pushes the component to reset after the pressure is released; the inner walls of the U-shaped hydraulic oil channel 275 and the rising channel 276 are smooth and filled with anti-wear hydraulic oil; the piston 274 and piston 277 are made of polytetrafluoroethylene, which combines wear resistance and sealing; the push rod 278 is made of stainless steel, and the lifting platform 279 is made of plastic with a silicone pad on the surface to further prevent scratches. The hydraulic drive enables the bottle to rise and fall smoothly.

[0052] The corrective lip plate 34 includes a hollow lip plate 341. Multiple evenly distributed telescopic holes are provided at the end of the hollow lip plate 341 away from the mounting plate 31. Matching flexible anti-tilt blocks 342 are slidably installed within the telescopic holes. A return spring 343 is fixedly connected between the flexible anti-tilt blocks 342 and the inner wall of the hollow lip plate 341. A base plate 344 is fixedly installed on the inner side of the hollow lip plate 341. Multiple T-shaped slide rails 345 corresponding to the flexible anti-tilt blocks 342 are fixedly installed on the upper end of the base plate 344. Matching magnetic sliders 346 are slidably installed on the T-shaped slide rails 345. A connecting rod 347 is fixedly connected between the magnetic sliders 346 and the flexible anti-tilt blocks 342. When the oral liquid medicine preparation bottle is lifted by the hydraulic actuator 27 and is in an unstable transmission state, the flexible anti-tilt plate 24 can prevent it from tilting away from the transfer assembly 4. While the bottle may tip over, there is still a risk of tipping over on the side closest to the transfer component 4. In this case, a flexible anti-tilting block 342 is used to block it and prevent it from tipping over. When the oral liquid preparation bottle needs to pass through the flexible anti-tilting block 342, the repulsive magnet 25 uses its magnetic field to repel the magnetic slider 346 from moving inward, thereby causing the flexible anti-tilting block 342 to move inward synchronously to avoid it, so that the oral liquid preparation bottle can pass through without being squeezed or scratched. After passing through the transfer base 21, it is reset by the elastic force of the reset spring 343. During the movement before contacting the transfer component 4, multiple flexible anti-tilting blocks 342 provide anti-tilting protection in sequence. The flexible anti-tilting blocks 342 will also avoid it in sequence under the indirect action of the repulsive magnet 25 until it contacts the transfer component 4 for transfer.

[0053] The hollow lip 341 is made of plastic, and the flexible anti-tilting stop 342 is made of silicone to avoid scratching the bottle body. The distance between them is slightly greater than the width of the bottle body. The reset spring 343 is a stainless steel spring that drives the stop to reset. The base plate 344 is made of plastic, the T-shaped slide rail 345 is made of aluminum alloy, the magnetic slider 346 is made of permanent magnet, and the connecting rod 347 is made of plastic. The repulsive force between the repulsive magnet 25 and the magnetic slider 346 can push the stop to avoid it, ensuring that the bottle body passes smoothly.

[0054] It should be noted that the entire device is powered by industrial 380V three-phase AC power. Power distribution and safety protection are achieved through components such as circuit breakers and leakage current protectors in the distribution box. For high-power equipment such as drive motor 105 and drive motor 244, 380V power is used directly. For low-power components such as electric push rod 32, negative pressure air pump 457, photoelectric displacement sensor 5, and pressure sensor 454, the 380V AC power is converted to 220V or 24V DC power through transformers in the distribution box to meet the voltage requirements of different components.

[0055] The device is equipped with a PLC control system. The PLC controller, as the core control unit, receives signals from detection elements such as the photoelectric displacement sensor 5 and pressure sensor 454. After logical operations, it sends control commands to actuators such as drive motor 105, drive motor 44, electric push rod 32, and negative pressure pump 457 to achieve coordinated operation of each component. The specific control logic is as follows: When the photoelectric displacement sensor 5 detects that the standing transfer component 2 has reached the designated position, it sends a signal to the PLC. The PLC controls the electric push rod 32 to extend, driving the trigger rod 33 to press the strip pressure plate 271, activating the hydraulic actuator 27 to lift the bottle. Simultaneously, based on the signal from the pressure sensor 454, when it detects that the bottle is in contact with the hollow adsorption half-set 453 and reaches the set pressure, the PLC controls the negative pressure pump 457 to start, achieving bottle adsorption. Subsequently, the PLC controls drive motor 44 to rotate, transferring the bottle to the packaging station 42. After the transfer is complete, the PLC controls the negative pressure pump 457 to stop, and the electric push rod 32 resets, waiting for the next standing transfer component to arrive. In addition, the device is equipped with a touch screen human-machine interface. Staff can set parameters such as transmission speed and trigger delay time through the touch screen and monitor the device's operating status in real time. When a fault occurs, the PLC will trigger an alarm function and display fault information on the touch screen, which will facilitate timely troubleshooting and repair by staff.

[0056] Working principle:

[0057] The working process mainly includes five stages: bottle feeding, linear transmission, trigger lifting, posture correction, and adsorption transfer. Each stage works together to achieve stable and scratch-free bottle transmission. The specific process is as follows:

[0058] First, the staff placed the bottles of oral liquid Chinese medicine preparations one by one into the standing holes 22 of the standing conveyor assembly 2. After the annular airbags 23 on the inner wall of the standing holes 22 were inflated, they were tightly attached to the bottle body to flexibly fix the bottle body and prevent the bottle body from shaking during the conveying process. At the same time, the flexible anti-tilting plate 24 relied on its own elasticity to attach to the side of the bottle body away from the conveying direction, providing the bottle body with preliminary anti-tipping protection.

[0059] Next, the device is started, and the drive motor 105 drives the drive pulley 102 to rotate through the reducer 106. The drive pulley 102 drives the driven pulley 103 to rotate synchronously through the conveyor belt 104, thereby realizing the linear transmission of the standing transmission component 2 on the conveyor belt 104. During the transmission process, the support frame 107 and support pulley 108 on the frame 101 support the conveyor belt 104 to prevent the conveyor belt from sagging and causing unstable transmission. The baffle 109 prevents the bottle from accidentally falling off the conveyor belt.

[0060] When the standing transmission component 2 moves to the area near the trigger component 3, a pair of photoelectric displacement sensors 5 detect the real-time position of the standing transmission component 2 and transmit the position signal to the PLC control system. After receiving the signal, the PLC control system determines that the standing transmission component 2 has reached the trigger position and then sends a control command to the electric push rod 32 of the trigger component 3. The electric push rod 32 extends, driving the trigger rod 33 to move inward. The drag-reducing ball 36 on the trigger rod 33 contacts and squeezes the strip pressure plate 271 in the strip groove 26 of the transmission base 21. A strip-shaped pressure plate 271 is pressed; after being subjected to pressure, the strip-shaped pressure plate 271 moves inward, overcoming the elastic force of the return spring 273, and pushes the piston 274 to move in the U-shaped hydraulic oil channel 275 through the pressure rod 272, squeezing the hydraulic oil in the U-shaped hydraulic oil channel 275; under the pressure of the hydraulic oil, the piston 277 in the rising channel 276 moves upward, and drives the lifting platform 279 to rise through the push rod 278. The lifting platform 279 pushes the traditional Chinese medicine oral liquid preparation bottle in the standing hole 22 to rise synchronously, realizing the lifting action of the bottle.

[0061] As the trigger rod 33 presses against the strip pressure plate 271, the corrective lip 34 connected to the trigger rod 33 via the bracket 35 moves inward simultaneously. The corrective lip 34 gradually approaches the bottle body, correcting the bottle's posture and preventing it from tilting during lifting. When the oral liquid preparation bottle continues to rise under the drive of the lifting platform 279 until it leaves the standing hole 22, the flexible anti-tilting plate 24 can prevent it from tilting backward, but there is still a risk of tilting forward. Moreover, the flexible anti-tilting stop 342 on the corrective lip 34 can limit its tilting angle, thereby protecting the bottle body. As the transmission base 21 continues to move with the conveyor belt 104, the left and right sides of the transmission base 21... When the repulsive magnet 25 at one end approaches the magnetic slider 346 of the straightening lip 34, the magnetic field generated by the repulsive magnet 25 exerts a repulsive force on the magnetic slider 346, pushing the magnetic slider 346 to move inward along the T-shaped slide rail 345. The magnetic slider 346 drives the flexible anti-tilting block 342 to move into the telescopic hole inside the hollow lip 341 through the connecting rod 347, avoiding the continuously moving bottle and preventing the flexible anti-tilting block 342 from contacting the bottle and causing scratching and squeezing. When the transmission base 21 continues to move and the repulsive magnet 25 moves away from the magnetic slider 346, the flexible anti-tilting block 342 is reset under the elastic force of the reset spring 343, continuing to provide anti-tipping protection for the bottles being transmitted subsequently.

[0062] When the bottle is lifted to contact the hollow adsorption half-set 453 of the transfer assembly 4, the pressure sensor 454 at the center of the hollow adsorption half-set 453 detects the contact pressure and transmits the pressure signal to the PLC control system. The PLC control system determines that the bottle has reached the adsorption position and immediately sends a start command to the negative pressure air pump 457. The negative pressure air pump 457 draws air from the hollow adsorption half-set 453 through the pipeline, creating a negative pressure state inside the hollow adsorption half-set 453. The adsorption holes 455 on the outer surface of the hollow adsorption half-set 453 generate adsorption force, firmly adsorbing the bottle onto the hollow adsorption half-set 453. Subsequently, the PLC control system sends a rotation command to the drive motor 44, which drives the rotating column 451 of the rotating transfer arm 45 to rotate. The rotating column 451 drives the extension arm 452 and the hollow adsorption half-set 453 to rotate synchronously, transferring the adsorbed bottle to the top of the packaging station 42. When the bottle reaches the designated position of the packaging station 42, the PLC control system controls the negative pressure air pump 457 to stop working, the negative pressure state in the hollow adsorption half-set 453 is released, the adsorption force disappears, and the bottle falls into the packaging station 42 for subsequent packaging processes. At the same time, the PLC control system controls the electric push rod 32 to retract, driving the trigger rod 33 and the straightening lip 34 to reset. The strip pressure plate 271 is reset under the elastic force of the reset spring 273, pushing the piston 274, piston 277, push rod 278 and lifting platform 279 to reset, waiting for the next standing transmission component 2 to arrive, and entering the next transmission cycle.
