Description

Technical Field

[0001] This application belongs to the technical field of medicine bottle delivery, and more specifically, relates to a bottle-retrieving structure. Background Technology

[0002] Medicine bottles are containers for holding medicines, mainly used for holding liquid, powder, or granular medicines. During the production and processing of medicine bottles, empty bottles need to be removed from the feeding area and placed onto a conveyor belt for subsequent operations.

[0003] The existing bottle-retrieving structure includes a frame and a cross module mounted on the frame. The frame is located at the feeding end of the conveyor belt, and a placement frame is mounted on the moving part of the cross module. The cross module moves the placement frame to the empty bottle feeding area. A cylinder in the empty bottle feeding area pushes one or more empty bottles onto the placement frame. The cross module then moves the placement frame onto the conveyor belt, and the cylinder pushes the empty bottles in the placement frame onto the conveyor belt.

[0004] During the process of the cross module moving the placement frame and empty medicine bottles onto the conveyor belt, the empty medicine bottles in the placement frame are easily tilted or tipped over by external factors, affecting the bottle retrieval efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a bottle-retrieving structure to solve the technical problem in the prior art where, during the process of the cross module driving the placement frame and empty medicine bottles to move onto the conveyor belt, the empty medicine bottles in the placement frame are easily tilted or tipped over by external factors, affecting the bottle-retrieving efficiency.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a bottle-retrieving structure, including a frame, a cross-shaped module disposed on the frame, and a placement frame disposed on the moving part of the cross-shaped module; the bottle-retrieving structure further includes: Several sets of clamping plates are arranged within the placement frame and along the conveyor belt conveying direction, with each set of clamping plates consisting of two plates arranged opposite each other; and Two sets of drive mechanisms are respectively arranged on both sides of the placement frame. The drive mechanisms are used to simultaneously drive the entire row of clamping plates located on the same side of the placement frame to move horizontally. When the two sets of drive mechanisms drive the two rows of clamping plates to move, the two rows of clamping plates move closer to each other or further away from each other. In one possible implementation, based on the above technical solutions, the bottle-removing structure further includes: Two movable frames are slidably disposed on both sides of the placement frame, the sliding direction of the movable frames being parallel to the conveyor belt conveying direction, and clamping plates are disposed on the corresponding movable frames; and Two sets of switching components are respectively disposed on both sides of the placement frame and connected between the corresponding drive mechanism and the moving frame; The drive mechanism has a first state and a second state, and the switching component is used to switch the drive mechanism between the first state and the second state. In the first state, the drive mechanism is connected to the clamping plate and is used to drive the clamping plate to move; in the second state, the drive mechanism is connected to the moving frame and is used to drive the moving frame to move until the clamping plate moves directly above the conveyor belt.

[0007] In one possible implementation, based on the above technical solutions, the driving mechanism includes: Several screws, each corresponding to a clamping plate, are threaded onto the movable frame, and the screws are rotatably connected to the clamping plates; Several guide members, each corresponding to one of the clamping plates, are connected between the clamping plates and the movable frame. The guide members are used to restrict the clamping plates to slide only along the direction of the screw axis. A plurality of transmission gears, each corresponding to a screw, are rotatably connected to the outside of the movable frame; the transmission gears are slidably connected coaxially to the screw; and A drive assembly is located on the outside of the movable frame and is used to drive the same row of transmission gears to rotate simultaneously.

[0008] In one possible implementation, based on the above technical solutions, a keyway is provided on the outer circumferential surface of the screw along its own axial direction, and a connecting key is fixed on the inner circumferential surface of the transmission gear, with the connecting key slidably disposed in the corresponding keyway.

In the first state, the drive gear meshes with one of the transmission gears. In the second state, the drive motor drives the transmission gears in the same row to reverse through the reversing member, so that each set of clamps moves away from each other.

[0010] In one possible implementation, based on the above technical solutions, the reversing component is a reversing gear, which is rotatably disposed on the outside of the movable frame and meshes with the transmission gear furthest from the conveyor belt; in the second state, the switching component is used to drive the drive gear to mesh with the reversing gear.

[0011] In one possible implementation, based on the above technical solutions, the switching component includes: A rack, fixed to the movable frame and located outside the placement frame, is also positioned directly below the transmission gear and the drive gear; and A drive cylinder is located on the outside of the placement frame, and the piston rod of the drive cylinder is connected to the lifting frame; The drive cylinder is used to drive the lifting frame to move up and down, so that the drive gear can switch between meshing with the transmission gear, meshing with the rack, or meshing with the reversing gear.

[0012] In one possible implementation, based on the above technical solutions, an elastic element is connected between the placement frame and the two movable frames; in the first state, the elastic element is in a free state; in the second state, the elastic element is in a stretched state.

[0013] In one possible implementation, based on the above technical solutions, the opposing surfaces of the two clamps in the same group are both arc-shaped.

[0014] In one possible implementation, based on the above technical solutions, guide plates are provided on both sides of the conveyor belt.

[0015] The beneficial effects of the bottle-retrieving structure provided in this application are as follows: Compared with the prior art, this application achieves effective fixation and operation of the medicine bottles in the placement frame by setting several sets of clamping plates and two sets of driving mechanisms; during the bottle retrieval process, the clamping plates can tightly clamp the medicine bottles by approaching each other, avoiding the problem of the medicine bottles tilting or tipping due to external factors (such as air flow, equipment vibration, etc.) when the cross module drives the placement frame and medicine bottles to move onto the conveyor belt, ensuring the stability of the medicine bottles during the movement process and greatly improving the bottle retrieval efficiency.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] The bottle-removing structure provided in this application will now be described.

[0024] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a bottle-retrieving structure, including a frame 1, a cross module 11, a placement frame 12, several sets of clamping plates 3, and two sets of driving mechanisms 4. The cross module 11 is mounted on the frame 1, and the placement frame 12 is mounted on the moving part of the cross module 11.

[0025] Several sets of clamping plates 3 are arranged in the placement frame 12 and along the conveying direction of the conveyor belt 2; each set of clamping plates 3 has two plates and is arranged opposite to each other; two sets of drive mechanisms 4 are respectively arranged on both sides of the placement frame 12, and the drive mechanisms 4 are used to simultaneously drive the entire row of clamping plates 3 located on the same side of the placement frame 12 to move horizontally; when the two sets of drive mechanisms 4 drive the two rows of clamping plates 3 to move, the two rows of clamping plates 3 move closer to each other or further away from each other.

[0026] This embodiment provides a bottle-retrieving structure that, compared to existing technologies, effectively fixes and manipulates the medicine bottles within the placement frame 12 by setting several sets of clamping plates 3 and two sets of driving mechanisms 4. During the bottle-retrieving process, the clamping plates 3, when close together, can tightly clamp the medicine bottles, preventing them from tilting or tipping due to external factors (such as airflow, equipment vibration, etc.) as the cross module 11 moves the placement frame 12 and the medicine bottles onto the conveyor belt 2. This ensures the stability of the medicine bottles during movement and greatly improves the bottle-retrieving efficiency. Moreover, the mobility of the clamping plates 3 allows this bottle-retrieving structure to adapt to medicine bottles of different sizes. By adjusting the distance between the clamping plates 3, various specifications of medicine bottles can be flexibly clamped, enhancing the versatility and applicability of the bottle-retrieving structure.

[0027] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottle-retrieving structure also includes two movable frames 5 and two sets of switching components 6; the two movable frames 5 are slidably arranged on both sides of the placement frame 12, and the sliding direction of the movable frames 5 is parallel to the conveying direction of the conveyor belt 2, and the clamping plate 3 is arranged on the corresponding movable frame 5; the two sets of switching components 6 are arranged on both sides of the placement frame 12 and connected between the corresponding drive mechanism 4 and the movable frame 5. The drive mechanism 4 has a first state and a second state, and the switching component 6 is used to switch the drive mechanism 4 between the first state and the second state. In the first state, the drive mechanism 4 is connected to the clamping plate 3 and is used to drive the clamping plate 3 to move; in the second state, the drive mechanism 4 is connected to the moving frame 5 and is used to drive the moving frame 5 to move until the clamping plate 3 moves directly above the conveyor belt 2.

[0028] In the first state, the drive mechanism 4 is connected to the clamping plate 3 and drives the clamping plate 3 to move, thereby achieving the function of clamping the medicine bottle and ensuring the stability of the medicine bottle during the movement.

[0029] In the second state, the drive mechanism 4 drives the moving frame 5 to move until the clamping plate 3 moves directly above the conveyor belt 2. At this time, the drive mechanism 4 is switched to the first state by the switching component 6. The drive mechanism 4 drives each set of clamping plates 3 to move away from each other, so that the medicine bottle can fall directly onto the conveyor belt 2 for conveying, which improves the accuracy and efficiency of medicine bottle placement.

[0030] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The drive mechanism 4 includes several screws 41, several guides 42, several transmission gears 43, and a set of drive components 44; the screws 41 correspond one-to-one with the clamping plates 3 and are threadedly connected to the movable frame 5, and the screws 41 are rotatably connected to the clamping plates 3; the guides 42 correspond one-to-one with the clamping plates 3 and are connected between the clamping plates 3 and the movable frame 5, and the guides 42 are used to restrict the clamping plates 3 to slide only along the axial direction of the screws 41; The transmission gear 43 corresponds one-to-one with the screw 41 and is rotatably connected to the outside of the movable frame 5. The transmission gear 43 and the screw 41 are slidably connected coaxially. The drive assembly 44 is located on the outside of the movable frame 5 and is used to drive the same row of transmission gears 43 to rotate simultaneously.

[0031] Specifically, in this embodiment, the guide member 42 is a telescopic rod, one end of which is connected to the clamping plate 3 and the other end is connected to the movable frame 5. The telescopic direction of the telescopic rod is parallel to the axis of the screw 41.

[0032] The threaded connection of the screw 41 converts rotary motion into linear motion, enabling smooth movement of the clamping plate 3. The guide member 42 ensures that the clamping plate 3 can only slide along the axis of the screw 41, preventing deviation during movement and ensuring the accuracy of its movement. The synchronous rotation of the transmission gear 43 allows the clamping plates 3 in the same row to move simultaneously, ensuring consistent clamping of the medicine bottle. The drive assembly 44 provides power to the entire drive mechanism 4.

[0033] When adjusting the distance between clamping plates 3 in the same group, the drive assembly 44 drives the transmission gears 43 in the same row to rotate simultaneously. The rotation of the transmission gears 43 drives the screw 41 to move in a spiral motion. At the same time, the clamping plates 3 are driven by the screw 41 and guided by the guide member 42 to move in a translational manner, which improves the moving efficiency of the clamping plates 3.

[0034] like Figures 3 to 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The outer circumferential surface of the screw 41 is provided with a keyway 411 along its own axis, and the inner circumferential surface of the transmission gear 43 is fixed with a connecting key 431, which is slidably disposed in the corresponding keyway 411.

[0035] Through the cooperation of keyway 411 and connecting key 431, the transmission gear 43 can drive the screw 41 to rotate synchronously when it rotates, thereby realizing the movement of clamping plate 3 and improving the stability of the cooperation between transmission gear 43 and screw 41.

[0036] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The drive assembly 44 includes a lifting frame 441, a drive motor 442, a drive gear 443, and a reversing component; the lifting frame 441 is slidably disposed on the outside of the placement frame 12; the drive motor 442 is disposed on the lifting frame 441; the drive gear 443 is coaxially fixed to the output shaft of the drive motor 442; the reversing component is disposed on the outside of the movable frame 5 and is used to connect between the transmission gear 43 and the drive motor 442 in the second state; In this configuration, the transmission gears 43 in the same row mesh with each other, and the threads of every two adjacent screws 41 are opposite in direction. In the first state, the drive gear 443 meshes with one of the transmission gears 43. In the second state, the drive motor 442 is used to drive the transmission gears 43 in the same row to reverse through the reversing component, so that each set of clamps 3 moves away from each other.

[0037] In the first state, the drive motor 442 is started to make the drive gear 443 rotate. The drive gear 443 drives all the transmission gears 43 to rotate through one of the transmission gears 43, so that multiple sets of clamps can clamp three pairs of medicine bottles at the same time.

[0038] After the placement box 12 moves onto the conveyor belt 2, the switching component 6 drives the drive mechanism 4 to switch to the second state, and then the drive component 44 drives the moving frame 5 to move in the conveying direction of the lower conveyor belt 2 until all the medicine bottles are moved directly above the conveyor belt 2.

[0039] At this point, the switching component 6 drives the drive mechanism 4 to switch to the first state, and the drive motor 442 drives the transmission gear 43 to reverse through the reversing component, so that the medicine bottle can be released and transported; the clamping plate 3 and the moving frame 5 can cooperate according to different working states, which improves the efficiency of picking up and putting down the bottle.

[0040] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The reversing component is a reversing gear 444, which is rotatably mounted on the outside of the movable frame 5 and meshes with the transmission gear 43 that is furthest from the conveyor belt 2. In the second state, the switching component 6 is used to drive the drive gear 443 to mesh with the reversing gear 444.

[0041] After the drive assembly 44 drives the moving frame 5 to move in the direction of the downward conveyor belt 2 until all the medicine bottles are moved directly above the conveyor belt 2, the switching assembly 6 drives the drive gear 443 to mesh with the reverse gear 444. At this time, the drive motor 442 is started, which drives all the transmission gears 43 to reverse through the reverse gear 444, thereby realizing that the clamping plates 3 move away from each other, making the state switching of the drive mechanism 4 more stable and reliable, and ensuring the normal operation of the bottle picking structure in different working modes.

[0042] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The switching assembly 6 includes a rack 61 and a drive cylinder 62; the rack 61 is fixed to the moving frame 5 and located outside the placement frame 12, and the rack 61 is also located directly below the transmission gear 43 and the drive gear 443; the drive cylinder 62 is located outside the placement frame 12, and the piston rod of the drive cylinder 62 is connected to the lifting frame 441. The drive cylinder 62 is used to drive the lifting frame 441 to rise and fall, so that the drive gear 443 can switch between meshing with the transmission gear 43, meshing with the rack 61, or meshing with the reverse gear 444.

[0043] In the first state, the drive gear 443 meshes with one of the transmission gears 43. After the placement frame 12 with the medicine bottle moves onto the conveyor belt 2, the drive cylinder 62 is activated to lower the lifting frame 441 until the drive gear 443 meshes with the rack 61. At this point, the drive motor 442 can be activated to drive the drive gear 443 to move the rack 61 and the moving frame 5 onto the lower conveyor belt 2. After all the medicine bottles have moved directly above the conveyor belt 2, the reversing gear 444 is located directly above the drive gear 443. The drive cylinder 62 is then activated to raise the lifting frame 441 until the drive gear 443 meshes with the reversing gear 444. At this point, the drive motor 442 can be activated to reverse the rotation of all the transmission gears 43, releasing the empty bottles onto the conveyor belt 2.

[0044] The lifting frame 441 is raised and lowered by the drive cylinder 62, so that the drive gear 443 can accurately mesh with the transmission gear 43, rack 61 or reverse gear 444, thereby realizing different actions of the clamping plate 3. The working state of the drive mechanism 4 can be quickly and accurately switched according to actual work needs, improving the operational flexibility and efficiency of the bottle picking structure.

[0045] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: An elastic element (not shown in the figure) is connected between the placement frame 12 and the two movable frames 5; in the first state, the elastic element is in a free state; in the second state, the elastic element is in a stretched state.

[0046] Specifically, in this embodiment, the elastic element can be a coil spring or a tension spring, with one end set on the placement frame 12 and the other end connected to the movable frame 5.

[0047] In the first state, the elastic element is in a free state, which does not affect the clamping operation of the clamping plate 3 on the medicine bottle. In the second state, the elastic element is in a stretched state. When the drive mechanism 4 switches from the second state back to the first state, the elastic force of the elastic element can help the moving frame 5 and the clamping plate 3 to be stably reset, thus improving the working efficiency of the bottle retrieval structure.

[0048] Meanwhile, the elastic element can also provide a force to the rack 61 to rotate in the opposite direction to the downward drive gear 443 when the moving frame 5 moves toward the conveyor belt 2, so as to improve the meshing stability of the rack 61 and the drive gear 443.

[0049] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The opposing surfaces of the two clamping plates 3 in the same group are both arc-shaped.

[0050] The arc shape allows the clamp 3 to better conform to the shape of the medicine bottle when holding it, increasing the contact area between the clamp 3 and the medicine bottle and improving the stability of the clamping. Furthermore, the arc surface better adapts to the round or near-round shape of the medicine bottle, avoiding localized compression of the medicine bottle by the clamp 3 and reducing the risk of damage to the medicine bottle during clamping.

[0051] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Guide plates 21 are provided on both sides of the conveyor belt 2.

[0052] The guide plate 21 can guide and limit the transmission of medicine bottles on the conveyor belt 2, prevent the medicine bottles from deviating or tipping over during transmission, and ensure that the medicine bottles can be transmitted smoothly along the center line of the conveyor belt 2, which helps to improve the accuracy and stability of medicine bottle transmission.

[0053] The above are merely preferred embodiments of this application and are not intended to limit this application.
