Abstract
Description
Technical Field
[0001] This application relates to the field of pharmaceutical handling, and in particular to an auxiliary lifting device for handling pharmaceuticals in a dosing system. Background Technology
[0002] In the field of chemical handling systems, the demand for chemical handling equipment is increasing daily due to the continuous expansion of industrial production scale and the gradual improvement of automation. Efficient, safe, and multifunctional handling equipment can significantly improve production efficiency, reduce labor costs, minimize the impact of human factors on the chemical handling process, and ensure the stability and reliability of the production process. Good chemical handling equipment can prevent leakage and damage of chemicals during handling, ensuring the quality and safety of chemicals, which is crucial for safe production in industries such as chemicals.
[0003] In the past, there were two main conventional methods for handling pharmaceuticals in dosing systems. One method involved using traditional mechanical clamps, which used the clamping force of mechanical structures to secure the pharmaceutical containers or materials. This method was suitable for pharmaceutical packaging with regular shapes and hard textures. The other method involved using simple hook devices to suspend the pharmaceutical containers or materials directly for handling. This method was relatively simple to operate, but it was not suitable for some irregularly shaped or easily damaged pharmaceutical packaging.
[0004] In addition, some suction cup lifting devices are used, but these suction cup lifting devices have a relatively fixed structure and a single adsorption function, making it difficult to meet the handling needs of drugs of different shapes and sizes.
[0005] However, existing handling methods have significant drawbacks. Traditional mechanical clamps and hooks are ill-suited for pharmaceutical packaging of different shapes and sizes, and can easily damage irregularly shaped or soft-textured packaging. Existing suction cup lifters have fixed structures and limited functionality, failing to adapt flexibly to different handling needs and unable to simultaneously meet the lifting and suction requirements for straight profiles, plates, and bagged materials. Summary of the Invention
[0006] To overcome the above-mentioned technical problems, this application provides an auxiliary lifting device for handling pharmaceuticals in a dosing system.
[0007] The auxiliary lifting device for handling pharmaceuticals in a dosing system provided in this application adopts the following technical solution: An auxiliary lifting device for handling pharmaceuticals in a dosing system includes a frame, an air source assembly mounted on the frame, and an adsorption assembly mounted on the frame and connected to the air source assembly. The adsorption assembly includes a mounting frame, a first suction frame fixed to the periphery of the mounting frame and connected to the air source assembly, several sets of second suction frames sliding on the mounting frame and connected to the air source assembly, and a third suction frame sliding on the mounting frame and connected to the air source assembly. The second suction frames are located between the first and third suction frames, and several second suction frames are sequentially nested. The third suction frame is located inside the second suction frames. The mounting frame is provided with a driving assembly for driving the second and third suction frames to slide. The mounting frame is also provided with a handheld assembly for controlling the adsorption state of the adsorption assembly.
[0008] By adopting the above technical solution, this auxiliary lifting device can flexibly meet the needs of handling pharmaceuticals of different shapes and types. When it is necessary to handle straight profiles, plates, and other objects, the second and third suction frames can be flush with the first suction frame by using the drive component. Activating the air source component causes the suction cups on each suction frame to generate suction, achieving stable lifting and adsorption of long, straight objects. When lifting material bags in chemical plants, operators can, depending on the size of the bag, drive the drive component to pull either the two second suction frames or only the third suction frame, allowing the suction cups of the entire mounting frame to form a groove, facilitating the adsorption of the material bag within the groove. Activating the air source component at this time allows the suction cups on each suction frame to perform their adsorption function. The handheld component allows operators to easily control the adsorption state of the adsorption component at any time, improving operational convenience and achieving a dual-purpose effect for multiple scenarios. Furthermore, the size of the groove can be adjusted according to the size of the pharmaceutical bag to better fit the material for adsorption.
[0009] Preferably, the first suction frame includes a plurality of first mounting shells with sealed inner cavities, a first suction cup disposed on the side of the first mounting shell facing away from the mounting frame, a first mounting opening opened on the side of the first mounting shell near the second suction frame, a first flexible plate fixed inside the first mounting opening, and a first sealing plate sliding outside the first mounting opening to prevent deformation of the first flexible plate. The plurality of first mounting shells are sequentially attached and surrounded to form a rectangular frame. The air source assembly is connected to the inner cavity of the first mounting shell, the first suction cup is connected to the inner cavity of the first mounting shell, and the first sealing plate has a first linkage groove on the side of the first mounting frame that is attached to the second mounting frame.
[0010] By adopting the above technical solution, a rectangular frame is formed by several sealed first mounting shells, which, together with a first suction cup connected to the air source component, can perform an adsorption operation on objects. A first flexible plate is provided, which, under certain conditions such as when the second suction frame moves and partially exposes the first flexible plate, can generate an adsorption force similar to that of a suction cup under the action of the air source component, enhancing the adsorption effect on objects, especially bagged objects. A sliding first sealing plate prevents unnecessary deformation of the first flexible plate, ensuring stable adsorption function. The first linkage groove on the first sealing plate can cooperate with the structure of other components, such as the second suction frame, to realize linkage and adjustment between different suction frames, so as to adapt to the adsorption needs of objects of different shapes and sizes.
[0011] Preferably, the second suction frame includes a plurality of second mounting shells with sealed inner cavities, a second suction cup disposed on the side of the second mounting shell facing away from the mounting frame, a second mounting opening opened on the side of the second mounting shell facing the third suction frame, a second flexible plate fixed inside the second mounting opening, and a second sealing plate sliding outside the second mounting opening to prevent deformation of the second flexible plate. The plurality of second mounting shells are sequentially attached and surrounded to form a rectangular frame. The air source assembly is connected to the second mounting shell, the second suction cup is connected to the inner cavity of the second mounting shell, and a plurality of first inserts are disposed on the side of the second suction frame facing the first suction frame. The first inserts are fixed on the second mounting shell, and a second linkage groove is provided on the second sealing plate.
[0012] By adopting the above technical solution, a multi-functional lifting device is achieved. For straight profiles, plates, and other objects, the second suction frame can be flush with the first suction frame to achieve the lifting and adsorption of long, straight objects. When lifting material bags in chemical plants, the second suction frame can be moved by adjustment, so that the suction cups of the entire mounting frame form a groove, achieving the lifting and adsorption of bagged items. During the sliding process of the second suction frame, through the action of the first insert and the second linkage groove, part of the flexible plate of the second mounting shell is exposed. When adsorbing bagged objects, the flexible plate deforms under the action of the vacuum pump to generate adsorption force, thereby achieving the adsorption of bagged objects.
[0013] Preferably, the third suction frame includes a plurality of third mounting shells with sealed inner cavities, a third suction cup disposed on the side of the third mounting shell facing away from the mounting frame, and a second insert block fixed on the side of the third mounting shell facing the second suction frame. The plurality of third mounting shells are sequentially attached and surrounded to form a rectangular frame. The air source assembly is connected to the third mounting shell, and the third suction cup is connected to the inner cavity of the third mounting shell.
[0014] By adopting the above technical solution, when the agent needs to be transported and adsorbed, the gas source component creates a negative pressure in the inner cavity of the third mounting shell. The third suction cup, which is connected to the inner cavity of the third mounting shell, generates an adsorption force, which can firmly adsorb the agent. At the same time, the second insert fixed to the side of the third mounting shell facing the second suction frame can be inserted into the inner cavity of the second linkage groove. During the movement of the third suction frame relative to the second suction frame, the second sealing plate is hooked and moved, thereby exposing the second flexible plate in the groove, which facilitates the adsorption of bagged materials in the groove, thus ensuring that the entire adsorption assembly can efficiently and stably complete the agent transport work.
[0015] Preferably, a first flexible cotton is fixed between the first suction cup and the outer wall of the first mounting shell, a second flexible cotton is fixed between the second suction cup and the outer wall of the second mounting shell, a third flexible cotton is fixed between the third suction cup and the outer wall of the third mounting shell, a plurality of fourth mounting shells are filled in the third suction frame, a fourth suction cup is disposed on the side of the fourth mounting shell facing away from the mounting frame, the air source assembly is connected to the fourth mounting shell, the fourth suction cup is connected to the inner cavity of the fourth mounting shell, and a fourth flexible cotton is fixed between the fourth suction cup and the outer wall of the fourth mounting shell.
[0016] By adopting the above technical solution, flexible cotton is fixed between the outer walls of the first suction cup and the first mounting shell, the second suction cup and the second mounting shell, the third suction cup and the third mounting shell, and the fourth suction cup and the fourth mounting shell, respectively. During the adsorption process, the flexible cotton is squeezed under the suction force, which can improve the sealing between the auxiliary lifting device and the drug being lifted. Since the adsorption force depends on the product of the area of the sealed suction cup and the vacuum degree, the improved sealing helps to enhance the adsorption effect, making the auxiliary lifting device more stable and reliable in transporting the drug in the dosing system.
[0017] Preferably, the driving assembly includes pull plates fixed to the first suction frame, the second suction frame, and the third suction frame on the side facing the mounting frame, an electric push cylinder fixed to the side wall of the mounting frame, a locking structure disposed between two adjacent pull plates, and an adjusting component installed on the side wall of the mounting frame to drive the locking structure to unlock. The size of the pull plates is adapted to the size of the first suction frame, the second suction frame, and the third suction frame, and the piston rod of the electric push cylinder is fixedly connected to the pull plates.
[0018] By adopting the above technical solution, the sliding of the first suction frame, the second suction frame, and the third suction frame is achieved by using an electric push cylinder to drive the pull plate. The position of the suction frame can be adjusted as needed to adapt to pharmaceutical packaging of different shapes and sizes. The locking structure can fix adjacent pull plates when they are attached, ensuring stable operation of the suction frame. The adjustment component can drive the locking structure to unlock, which facilitates flexible adjustment of the suction frame combination state and improves the versatility and flexibility of the auxiliary lifting tool.
[0019] Preferably, the locking structure includes a slot on one of the pull plates' sidewalls, a push block sliding within the slot, a first elastic element fixed to the push block, a slot on the other pull plate's sidewall that cooperates with the slot, a second elastic element on the slot, a slot on the pull plate's side facing away from the first suction frame, and an abutment block vertically sliding within the slot. The slot is connected to the slot. When two adjacent pull plates are in contact with each other, the slot is inserted into the slot under the action of the second elastic element, and the push block is pressed into the slot, causing the abutment block to be pushed up by the push block in the direction of disengaging from the slot. The end of the abutment block that abuts the push block is arc-shaped, and the end of the slot block that abuts the push block is also arc-shaped.
[0020] By adopting the above technical solution, the locking and unlocking functions between the suction frame pull plates of the auxiliary lifting device are realized. When adjacent pull plates are in contact, the locking block is inserted into the slot under the action of the second elastic element, and the push block is squeezed to push up the abutment block, thus completing the locking and ensuring that the pull plate connection is stable, thereby ensuring that the position of the suction frame is relatively fixed. Through subsequent cooperation with the adjustment component, the abutment block can be moved to separate the locking block from the slot, thus completing the unlocking. This facilitates the electric push cylinder to drive the pull plate to slide the suction frame, so as to adapt to the lifting needs of objects of different shapes.
[0021] Preferably, the adjusting component includes a pressure rod sliding on the side wall of the mounting frame, an arcuate protrusion on the side of the pressure rod extending into the inner cavity of the mounting frame, and a pull ring fixed to the end of the pressure rod extending out of the mounting frame. In the initial state, the end of the abutment block away from the push block is located between the pull ring and the arcuate protrusion and abuts against the pressure rod. A positioning ball slides on the side wall of the mounting frame, and a third elastic element for resetting the positioning ball is also provided on the side wall of the mounting frame. Positioning grooves for accommodating the positioning ball are spaced apart on the side wall of the pressure plate.
[0022] By adopting the above technical solution, the position of the suction frame of the adsorption component can be adjusted and controlled. The state of the suction frame can be adjusted according to different hoisting requirements. For example, when hoisting material bags, the suction cup of the installation frame can be made to present a groove to adapt to bags of different sizes. The positioning ball and the positioning groove can be used to achieve the adjusted positioning, which is convenient for operation. The adsorption range and shape can be flexibly changed according to the actual situation to achieve the effect of saving power consumption. At the same time, the flexible cotton is used to improve the sealing between the material being hoisted and the material being hoisted.
[0023] Preferably, the gas source assembly includes a vacuum pump fixed on the frame, a gas guide pipe disposed on the frame and connected to the vacuum pump, a pressure relief valve disposed on the gas guide pipe, and a filter. The end of the gas guide pipe away from the vacuum pump is connected to the inner cavity of the first mounting shell, the second mounting shell, the third mounting shell, and the fourth mounting shell respectively through a gas pipe.
[0024] By adopting the above technical solution, the vacuum pump provides the vacuum environment required for adsorption of the adsorption components, the pressure relief valve can adjust the pressure in the gas guide tube, the filter can filter gas impurities to ensure the cleanliness of the gas source, and the gas tube connects the vacuum pump to the inner cavity of each mounting shell to realize the adsorption function of the first suction frame, the second suction frame, the third suction frame and the fourth mounting shell, thereby completing the drug handling.
[0025] Preferably, the handheld assembly includes a handle fixed to the outer wall of the mounting frame, a first button on the handle for controlling the operation of the vacuum pump, and a second button on the handle for controlling the operation of the electric cylinder.
[0026] By adopting the above technical solution, a handle is set on the outer wall of the mounting frame to facilitate the operator to hold the auxiliary lifting tool; a first button to control the operation of the vacuum pump and a second button to control the operation of the electric push cylinder are set on the handle, which allows the operator to conveniently control the adsorption state of the adsorption component and drive the adsorption frame to slide, thereby improving the convenience and efficiency of operation.
[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. It can achieve multi-functional hoisting, making the second and third suction frames flush with the first suction frame, and can hoist and adsorb long and straight objects. It can also adjust the suction cups of the mounting frame to form a groove, so as to hoist and adsorb bag-shaped items. 2. When the first or second suction frame slides, the flexible plate is exposed through the action of the insert block and the linkage groove. Under the action of the vacuum pump, it generates an adsorption force similar to a suction cup, thereby adsorbing the bagged object and achieving a dual-purpose effect. 3. The addition of flexible cotton, which is squeezed during adsorption, improves the seal between the cotton and the material being lifted, thereby enhancing the effective sealing. The size of the adsorption groove can also be adjusted by controlling the pressure rod, saving power consumption. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.
[0030] This application discloses an auxiliary lifting device for transporting pharmaceuticals in a dosing system.
[0031] Reference Figure 1 The auxiliary lifting device for handling medicines in a dosing system provided in this application embodiment includes a frame 1, an air source component 2, an adsorption component 3, a drive component 8, and a handheld component 9. The frame 1 serves as the overall support structure for the auxiliary lifting device, used to support and fix other components, ensuring the structural stability and reliability of the lifting device during handling operations.
[0032] Reference Figure 1The gas source component 2 provides the necessary vacuum or negative pressure environment for the adsorption component 3, serving as the core power source for adsorption. The adsorption component 3 directly contacts the pharmaceutical agent to be transported and generates adsorption force, thereby enabling the grasping and transport of the agent. This component is essential for the lifting device to achieve its core functions.
[0033] Reference Figure 1 The driving component 8 provides power to enable rapid adjustment of the shape of the adsorption component 3, thereby adapting to the needs of handling pharmaceuticals of different sizes and shapes.
[0034] Reference Figure 1 The handheld component 9 provides a convenient control interface for operators to control the adsorption state of the adsorption component 3 and the operation of the drive component 8, thereby improving the ease of operation and efficiency of the auxiliary lifting device.
[0035] Reference Figure 2 and Figure 3 Specifically, the adsorption assembly 3 includes a mounting frame 4, a first suction frame 5, a second suction frame 6, and a third suction frame 7. The mounting frame 4 is the basic frame of the entire adsorption assembly 3, providing mounting positions for other components.
[0036] Reference Figure 2 and Figure 4 The first suction frame 5 includes a first mounting shell 10 with several sealed inner cavities, a first suction cup 11, a first mounting port 12, a first flexible plate 13, and a first sealing plate 14.
[0037] Reference Figure 2 and Figure 4 Specifically, the first mounting shell 10 is the basic unit constituting the first suction frame 5, and its inner cavity is a sealed structure to ensure a stable negative pressure environment during the adsorption process. The first mounting shell 10 can be made of one-piece molded plastic or metal material, and its wall surface is made smooth and seamless through precision machining. The connection is sealed by means of O-rings, sealing gaskets or sealant.
[0038] Reference Figure 4 The first suction cup 11, located on the side of the first mounting shell 10 facing away from the mounting frame 4, is the component that directly contacts the object being adsorbed. Its main function is to firmly adsorb the object by means of atmospheric pressure difference when a negative pressure is formed inside the first mounting shell 10. The first suction cup 11 can be integrally molded from elastic materials such as rubber or silicone and fixed to the outside of the first mounting shell 10 by means of bonding, snap-fit, or threaded connection; or, the first suction cup 11 can be designed with a multi-layer corrugated or pleated structure to increase its deformation capability and adaptability to irregular surfaces.
[0039] Reference Figure 2 and Figure 4 The first mounting opening 12, located on the side of the first mounting shell 10 near the second suction frame 6, is a pre-reserved opening on the first mounting shell 10. This opening provides the structural basis for the subsequent installation of the first flexible plate 13 and the first sealing plate 14. The first mounting opening 12 can be a rectangular or elongated through hole, formed on the side wall of the first mounting shell 10 through processes such as milling, stamping, or injection molding. The first flexible plate 13, fixed inside the first mounting opening 12, is a thin plate-like structure with good flexibility. Its core function is to deform when a negative pressure is generated inside the first mounting shell 10, thereby better conforming to irregular object surfaces, especially the folds of bagged objects, to enhance the sealing and stability of the adsorption.
[0040] Reference Figure 2 and Figure 4 In this embodiment, several first mounting shells 10 are sequentially attached to form a unified rectangular frame structure. The suction cups at the four corners of the rectangular frame structure are conventional suction cup structures. This combination allows the first suction frame 5 to form a large and continuous adsorption area, thus adapting to objects of different sizes and shapes, especially long or plate-shaped objects. The first mounting shells 10 can be fixedly connected by bolts, rivets, clips, or welding to ensure a tight fit. When the air source assembly 2 is working, it can extract air from the inner cavity of the first mounting shell 10, creating a negative pressure. When the second suction frame 6 is pulled, the first suction cup 11 and the first flexible plate 13 generate an adsorption force, resulting in the largest adsorption cavity size.
[0041] Reference Figure 4 The first linkage groove 15 is formed on the first sealing plate 14. When the second suction frame 6 moves, it cooperates with the first linkage groove 15, thereby driving the first sealing plate 14 to slide, and thus controlling the exposure or coverage state of the first flexible plate 13.
[0042] Reference Figure 2 and Figure 5 The second suction frame 6 includes a second mounting shell 16, a second suction cup 17, a second mounting port 18, a second flexible plate 19, and a second sealing plate 20. Specifically, the second suction frame 6 is a sliding part of the adsorption assembly 3, and its main function is to provide an adjustable adsorption area to accommodate pharmaceutical packages of different shapes and sizes. The second suction frame 6 can be made of lightweight, high-strength materials, such as aluminum alloy, engineering plastics, or composite materials. The second mounting shell 16, with several sealed cavities, is the basic unit constituting the second suction frame 6, and its interior is a sealed space.
[0043] Reference Figure 3 and Figure 5The second suction cup 17, located on the side of the second mounting housing 16 facing away from the mounting frame 4, is a component that directly contacts the transported agent and generates adsorption force. The second suction cup 17 can be made of wear-resistant and corrosion-resistant rubber or silicone material, and its shape can be circular, elliptical, or rectangular to adapt to different adsorption needs.
[0044] Reference Figure 5 The second mounting opening 18, located on the side of the second mounting housing 16 facing the third suction frame 7, is an opening for accommodating the second flexible plate 19. This mounting opening can be designed as rectangular or elongated to ensure that the second flexible plate 19 can be effectively exposed and function when needed. The second flexible plate 19, fixed within the second mounting opening 18, is a thin, elastic diaphragm or sheet. It can be made of highly elastic, fatigue-resistant materials such as silicone, polyurethane, or natural rubber, and its function is to deform under vacuum. The second sealing plate 20, sliding outside the second mounting opening 18 to prevent deformation of the second flexible plate 19, is a movable cover.
[0045] Reference Figure 2 and Figure 5 Several second mounting shells 16 are sequentially attached and surrounded to form a rectangular frame, enabling it to slide and adhere as a whole.
[0046] Reference Figure 5 The second suction cup 17 is connected to the inner cavity of the second mounting shell 16, ensuring that the vacuum can directly act on the second suction cup 17 to generate an adsorption force. Several first inserts 21 are provided on the side of the second suction frame 6 facing the first suction frame 5. These inserts can be protruding pins, buckles, or guide blocks. The first inserts 21 are fixed to the second mounting shell 16 and cooperate with the first linkage groove 15. A second linkage groove 22 is provided on the second sealing plate 20, located on the side opposite to the first inserts 21.
[0047] Reference Figures 1-6 The third suction frame 7 includes a third mounting shell 23, a third suction cup 24, and a second insert block 25. The material and structure of the third mounting shell 23 are similar to those of the first mounting shell 10 and the second mounting shell 16, and the material of the third suction cup 24 is the same as that of the first suction cup 11 and the second suction cup 17. Several third mounting shells 23 are sequentially attached and surrounded to form a rectangular frame. The air source assembly 2 is connected to the third mounting shell 23, and the third suction cup 24 is connected to the inner cavity of the third mounting shell 23.
[0048] Reference 1- Figure 6The third suction frame 7 is a sliding part of the adsorption assembly 3. Its main function is to work in conjunction with the first suction frame 5 and the second suction frame 6 to adapt to the needs of drug handling of different shapes and sizes. It can be independent or linked with other suction frames to form different adsorption configurations. The third mounting shell 23, which has several sealed cavities, is the basic unit constituting the third suction frame 7. Its cavities are designed as a sealed structure.
[0049] Reference Figure 2 , Figure 5 and Figure 6 The third suction frame 7 can be formed by connecting and fixing multiple independent third mounting shells 23 together to form an integral rectangular frame. The inner cavity of each third mounting shell 23 can be made of one-piece molded polycarbonate material to ensure its sealing. The third suction cup 24 can be a silicone suction cup with a corrugated edge design to increase the adhesion to the surface of the medicine. The third suction cup 24 communicates with the inner cavity of the third mounting shell 23 and is sealed with an O-ring. The second insert 25 is fixed to the side of the third mounting shell 23 facing the second suction frame 6, and its shape is designed as a protruding structure that matches the second linkage groove 22 on the second suction frame 6.
[0050] Reference 1- Figure 6 To achieve effective linkage with the second suction frame 6, when the drive assembly 8 drives the third suction frame 7 to slide on the mounting frame 4, the second insert 25 is located in the second linkage groove 22 on the second suction frame 6. This allows the movement of the third suction frame 7 to drive the second sealing plate 20 on the second suction frame 6 to slide accordingly, thereby exposing the second flexible plate 19. When the second flexible plate 19 is exposed, under the negative pressure generated by the air source assembly 2, the second flexible plate 19 can deform and generate additional adsorption force, which is especially suitable for adsorbing irregularly shaped bagged materials.
[0051] Reference Figures 4-6 To further enhance the adsorption effect, this application further proposes that a first flexible cotton 26 is fixed between the first suction cup 11 and the outer wall of the first mounting shell 10, a second flexible cotton 27 is fixed between the second suction cup 17 and the outer wall of the second mounting shell 16, a third flexible cotton 28 is fixed between the third suction cup 24 and the outer wall of the third mounting shell 23, a plurality of fourth mounting shells 29 are filled in the third suction frame 7, a fourth suction cup 30 is disposed on the side of the fourth mounting shell 29 facing away from the mounting frame 4, the air source component 2 is connected to the fourth mounting shell 29, the fourth suction cup 30 is connected to the inner cavity of the fourth mounting shell 29, and a fourth flexible cotton 31 is fixed between the fourth suction cup 30 and the outer wall of the fourth mounting shell 29.
[0052] Reference Figures 4-6Among them, the first flexible cotton 26, the second flexible cotton 27, the third flexible cotton 28, and the fourth flexible cotton 31 are material layers with a certain degree of elasticity and compressibility, usually made of foamed rubber, silicone, polyurethane foam, or similar elastomer materials. Their function is to fill any tiny gaps or unevenness that may exist between the edge of the suction cup and the surface of the object being adsorbed when the suction cup adsorbs an object, thereby forming a tighter seal, preventing air leakage, and improving the stability and efficiency of adsorption. For example, they can be fixed by adhesive, snap-fit, or embedding.
[0053] Reference Figure 2 , Figure 6 The fourth mounting shell 29 is an independent adsorption unit disposed within the third suction frame 7, and its inner cavity is sealed. The function of the fourth mounting shell 29 is to serve as an additional adsorption point, particularly for the central area of the material, compensating for the shortcomings of traditional suction frame edge adsorption. For example, the fourth mounting shell 29 can be designed as rectangular, circular, or elliptical, and filled in an array within the internal space of the third suction frame 7. The fourth suction cup 30 is an adsorption component disposed on the side of the fourth mounting shell 29 facing away from the mounting frame 4, and is typically made of wear-resistant, highly elastic rubber or silicone material.
[0054] Reference Figure 7 and Figure 8 The drive assembly 8 includes a pull plate 32, an electric push cylinder 33, a locking structure disposed between two adjacent pull plates 32, and an adjustment component mounted on the side wall of the mounting frame 4 to drive the locking structure to unlock.
[0055] Reference Figure 7 and Figure 8 The function of the pull plate 32 is to transmit the thrust or pull force generated by the electric push cylinder 33 to the first suction frame 5, the second suction frame 6, and the third suction frame 7, thereby realizing the sliding of the suction frames. The size of the pull plate 32 is adapted to the size of the first suction frame 5, the second suction frame 6, and the third suction frame 7, and the piston rod of the electric push cylinder 33 is fixedly connected to the pull plate 32. The electric push cylinder 33, as a power source, drives the pull plate 32 to move through the extension and retraction of the piston rod, thereby realizing the sliding of the suction frames.
[0056] Reference Figure 3 and Figure 8 The locking structure serves to lock adjacent pull plates 32 together after the suction frame moves to the predetermined position, preventing accidental displacement of the suction frame due to external vibration, impact, or gravity, thereby ensuring the stability and safety of the adsorption assembly 3. The locking structure is typically a mechanical self-locking mechanism that automatically engages when the pull plates 32 are in contact and is released by external force when unlocking is required.
[0057] Reference Figure 8 and Figure 9The specific locking structure includes a slot 34, a push block 35 sliding within the slot 34, a first elastic element 36 fixed to the push block 35, a slot 37 sliding on the side wall of another pull plate 32 and engaging with the slot 34, a second elastic element 38 disposed on the slot 37, a slot 39 formed on the side of the pull plate 32 facing away from the first suction frame 5, and an abutment block 40 sliding vertically within the slot 39. In this embodiment, the number of slots 34 is determined according to the number of movable pull plates 32. The slot 39 is connected to the slot 34. When two adjacent pull plates 32 are in contact with each other, the slot 37 is inserted into the slot 34 under the action of the second elastic element 38, and the push block 35 is pressed into the slot 34, causing the abutment block 40 to be pushed up by the push block 35 in the direction of disengaging from the slot 39. The end of the abutment block 40 that abuts the push block 35 is arc-shaped, and the end of the slot 37 that abuts the push block 35 is also arc-shaped. The first elastic element 36 and the second elastic element 38 can be springs, which serve as buffers and resets.
[0058] Reference Figure 8 and Figure 9 When the drive assembly 8 drives two adjacent pull plates 32 to approach and fit together, the locking block 37, located on the side wall of one of the pull plates 32, automatically slides and inserts into the preset slot 34 on the side wall of the other pull plate 32 under the continuous elastic force applied by the second elastic member 38. During the insertion of the locking block 37 into the slot 34, its arc-shaped abutment end smoothly contacts and presses the push block 35 sliding in the slot 34. Since the slot 34 is connected to the slot 39, the push block 35, after being pressed, moves towards the slot 39 and pushes up the abutment block 40 that slides vertically in the slot 39, causing the abutment block 40 to be lifted in the direction of disengaging from the slot 39. At this time, the locking block 37 is fully inserted into the slot 34, and the two pull plates 32 are firmly mechanically locked together, thereby fixing the position of the suction frame and preventing relative movement.
[0059] Reference Figure 8 and Figure 9 When unlocking is required, the adjusting component acts on the raised abutment block 40, pressing it downwards back into the slot 39. As the abutment block 40 moves downwards, the compressive force on the push block 35 is released, and under the elastic force of the first elastic element 36, the push block 35 automatically returns to its initial position. The reset of the push block 35 allows the locking block 37 to be unobstructed, thus smoothly exiting from the slot 34 and completing the unlocking process. Throughout the locking and unlocking process, the end of the abutment block 40 that abuts against the push block 35 and the end of the locking block 37 that abuts against the push block 35 are both arc-shaped. This design greatly reduces friction and impact between components, ensuring smooth and stable locking and unlocking actions, and effectively avoiding the jamming or wear problems common in traditional mechanical locking.
[0060] Reference Figure 7 and Figure 10The adjusting components include a pressure rod 41 that slides on the side wall of the mounting frame 4, an arcuate protrusion 42 located on the side of the pressure rod 41 that extends into the inner cavity of the mounting frame 4, and a pull ring 43 fixed to the end of the pressure rod 41 that extends out of the mounting frame 4. In the initial state, the end of the abutment block 40 away from the push block 35 is located between the pull ring 43 and the arcuate protrusion 42, and abuts against the pressure rod 41.
[0061] Reference Figure 7 and Figure 10 A positioning ball 44 slides on the side wall of the mounting frame 4, and a third elastic element 45 for resetting the positioning ball 44 is also provided on the side wall of the mounting frame 4. Positioning grooves 46 for accommodating the positioning ball 44 are spaced apart on the side wall of the pressure rod 41. By pulling the pull ring 43, the pressure rod 41 moves, causing the abutment block 40 to disengage from the restriction of the pressure rod 41, thereby unlocking the locking structure and realizing the independent movement of the suction frame.
[0062] Reference Figures 7-10 When the position of one of the suction frames in the adsorption assembly 3 needs to be adjusted, the operator pulls the pull ring 43 fixed to the end of the pressure rod 41 that extends out of the mounting frame 4, causing the pressure rod 41 to slide along the side wall of the mounting frame 4. During the sliding process of the pressure rod 41, the arc-shaped protrusion 42 on the side of the pressure rod 41 that extends into the inner cavity of the mounting frame 4 will contact the abutment block 40 in the locking structure. Due to the curved surface characteristics of the arc-shaped protrusion 42, it can smoothly push the abutment block 40, so that it overcomes the squeezing action of the push block 35, thereby causing the abutment block 40 to be pushed up in the direction of disengaging from the slot 39. The movement of the abutment block 40 then causes the locking block 37 to separate from the locking groove 34, thereby unlocking the adjacent pull plates 32. When the pressure rod 41 slides to the preset position, the positioning ball 44 sliding on the side wall of the mounting frame 4 will automatically engage in the positioning groove 46 on the side wall of the pressure plate, which is spaced apart to accommodate the positioning ball 44, under the action of the third elastic element 45 for resetting the positioning ball 44. The cooperation between the positioning ball 44 and the positioning groove 46 precisely locks the pressure rod 41 in its current position, ensuring that the position of the suction frame after adjustment of the drive assembly 8 can be stably maintained, avoiding displacement caused by vibration or external force. Through this mechanism, the adjustment component not only provides a convenient unlocking method, but also provides reliable positioning assurance for the flexible adjustment of the suction frame. This design allows the auxiliary lifting device to quickly and accurately adjust the configuration of the adsorption assembly 3 according to the shape and size of different pharmaceutical packages, greatly improving operational efficiency and adsorption adaptability.
[0063] Reference Figures 1-6The gas source assembly 2 includes a vacuum pump 47, a gas guide pipe 48, a pressure relief valve 49, and a filter 50. The end of the gas guide pipe 48 furthest from the vacuum pump 47 is connected via gas pipes to the inner cavities of the first mounting housing 10, the second mounting housing 16, the third mounting housing 23, and the fourth mounting housing 29. The vacuum pump 47 provides the negative pressure required for adsorption, the pressure relief valve 49 regulates the gas pressure, and the filter 50 prevents impurities from entering the suction frame, ensuring effective adsorption.
[0064] Reference Figures 1-6 Specifically, the vacuum pump 47 can be a rotary vane vacuum pump with a rated pumping speed of 60 cubic meters per hour, such as an industrial vacuum pump 47 of a certain brand and model SV60. This vacuum pump 47 is fixed on the frame 1, and its air inlet is connected to the filter 50 via a DN25 rigid stainless steel air guide pipe 48. The filter 50 can be a two-stage filtration device. The first stage is a particulate filter 50, used to remove solid particles with a diameter greater than 5 micrometers. The second stage is a coalescing filter 50, used to remove oil mist and moisture, ensuring the cleanliness of the air source. This filter 50 is installed on the air guide pipe 48, located at the air inlet end of the vacuum pump 47. After the filter 50, a spring-loaded pressure relief valve 49 can be installed on the air guide pipe 48, with a set opening pressure of -0.08 MPa to prevent excessive negative pressure in the system. The end of the air guide tube 48 is split via a four-way connector and connected to the inner cavities of the first mounting housing 10, the second mounting housing 16, the third mounting housing 23, and the fourth mounting housing 29 via four pressure-resistant rubber air tubes with an inner diameter of 10mm. These air tubes are connected to the mounting housings using quick-connect couplings for easy maintenance and replacement. When the vacuum pump 47 is started, it transmits the negative pressure, purified by the filter 50 and stabilized by the pressure relief valve 49, evenly to the inner cavities of all mounting housings through the stainless steel air guide tube 48 and the pressure-resistant rubber air tubes, thereby driving each suction cup to generate suction force.
[0065] Reference Figures 1-3The handheld component 9 includes a handle 51, a first button 52, and a second button 53. The operator can easily operate the lifting device using the handle 51, and control the operation of the vacuum pump 47 and the electric pusher cylinder 33 using the first button 52 and the second button 53, respectively. The handle 51 is fixed to the outside of the mounting frame 4. The first button 52 is a mechanical switch used to trigger a specific electrical signal; its main function is to control the start and stop of the vacuum pump 47, thereby directly controlling the suction state of the adsorption component 3. The first button 52 can be designed as a momentary trigger button, meaning that the vacuum pump 47 starts when pressed and stops when released, or stops when pressed again. Alternatively, the first button 52 can be a self-locking button, remaining energized when pressed and de-energized when pressed again, thus enabling continuous operation or stopping of the vacuum pump 47. The second button 53 is also a mechanical switch used to trigger a specific electrical signal; its function is to control the extension and retraction of the electric pusher cylinder 33, thereby driving the suction frame to slide and adjust the shape of the adsorption component 3. The second button 53 can be designed as a two-way button, with one direction used to control the extension of the electric push cylinder 33 and the other direction used to control the retraction of the electric push cylinder 33, thereby realizing the forward or backward sliding of the suction frame. Alternatively, two independent buttons can be used, one specifically for controlling the extension of the electric push cylinder 33 and the other for controlling the retraction of the electric push cylinder 33.
[0066] The implementation principle of this embodiment is as follows: This auxiliary lifting device, through the combination of various suction frames and its adjustable structure, can adapt to the handling of pharmaceuticals of different shapes and sizes. For straight profiles, plates, and other objects, the second suction frame 6 and the third suction frame 7 can be flush with the first suction frame 5 to achieve the lifting and adsorption of long, straight objects. For bag-shaped items, depending on the size of the bag, the pull ring 43 can be adjusted to move part of the suction frame, making the suction cup of the entire mounting frame 4 present a groove, thus achieving the lifting and adsorption of the material bag. At the same time, during the sliding of the suction frame, some flexible plates of the mounting shell are exposed, generating an adsorption force similar to that of a suction cup under the action of the vacuum pump 47. The flexible cotton setting improves the sealing of the adsorption and increases the adsorption efficiency.
[0067] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
