Description

Technical Field

[0001] The present invention relates to a filling device.

Background Art

[0002] The existing filling device includes a frame and a row of filling valves mounted on the frame. The filling valves are used to fill materials into containers. In order to be able to clean the inside of the filling valves online, a cleaning return pipe and a translation cylinder are also provided on the existing frame. The cleaning return pipe is slidably mounted on the frame. The power output end of the translation cylinder is connected to the cleaning return pipe and drives the cleaning return pipe to perform a linear reciprocating motion. An inlet for docking with the filling valve is provided on the cleaning return pipe. The movement path of the cleaning return pipe intersects with the movement path of the filling valve. When it is necessary to clean the filling valve, the translation cylinder drives the cleaning return pipe to slide until the inlet is docked with the discharge port of the filling valve, so that the cleaning agent flowing through the filling valve flows into the cleaning return pipe and is discharged. When it is necessary to fill the container, the translation cylinder drives the cleaning return pipe to slide in the reverse direction and reset to avoid the container to be filled. It can be seen from this that based on the existing movement mode of the cleaning return pipe, only one row of filling valves can be provided in the existing filling device, that is, the number of filling valves provided on the frame is reduced, and the production efficiency is reduced.

[0015] Beneficial effects of the present invention:

[0016] 1. When the filling valve of the filling device of the present invention needs to be cleaned, the driving component first drives the movable rod to rotate, so that the two blocking covers rotate to align with the cleaning pipe in the vertical direction, and then the driving component drives the movable rod to drive the blocking cover to rise so that the blocking cover is in the first position. At this time, the blocking cover seals the bottom end of the cleaning pipe, and the cleaning agent for flushing the filling valve enters the guide pipe from the discharge port and flows to the cleaning channel, and flows out from the sewage channel; when the container needs to be filled, the driving component first drives the movable rod to descend, so that the two blocking covers are away from the cleaning pipe, and then the driving component drives the movable rod to drive the blocking cover to rotate in the opposite direction to reset so that the blocking cover is in the second position. At this time, the blocking cover and the cleaning pipe are staggered in the vertical direction, and the bottom end of the cleaning pipe and the bottom end of the guide pipe are open. The container to be filled is placed under the cleaning pipe, so that the guide pipe fills the container. It can be seen that the filling device of the present invention can be equipped with two rows of filling valves on the frame by changing the movement mode of the cleaning structure and its blocking cover, thereby increasing the number of filling valves and improving production efficiency.

[0017] 2. The bottom end of the cleaning pipe is lower than the bottom end of the material guide pipe. When the plugging cover is in the first position, the plugging cover is sleeved on the bottom end of the cleaning pipe. The way in which the plugging cover is sleeved on the bottom end of the cleaning pipe can improve the sealing performance of the plugging cover sealing the bottom end of the cleaning pipe to avoid leakage of the cleaning agent.

[0018] 3. The cleaning pipe includes a matching section that matches the plugging cover, and the outer diameter of the matching section gradually decreases from top to bottom. Such a design can facilitate the plugging cover to be smoothly mounted on the bottom end of the cleaning pipe.

[0019] 4. The frame also includes a second carrier plate located above the first carrier plate, the driving component includes a first cylinder, a rack slidably mounted on the second carrier plate, and a gear meshed with the rack, the movable rod is rotatably mounted on the second carrier plate, the gear is mounted on the upper end of the movable rod, the first cylinder includes a first telescopic rod connected to the rack, the first telescopic rod drives the rack to slide when it is horizontally extended, and the rack sliding drives the gear to drive the movable rod to rotate. With such a design, when the first telescopic rod is horizontally extended, it can drive the rack to slide, and the rack sliding will drive multiple gears to rotate, and each gear will drive the movable rod connected thereto to rotate, thereby driving the blocking cover and the cleaning pipe to achieve alignment or misalignment in the vertical direction. The overall structure is relatively simple and the assembly is relatively convenient, thereby reducing the equipment cost.

[0020] 5. The top surface of the second loading plate is also provided with a plurality of brackets spaced along the length direction of the rack, and a slide groove is provided on the bracket. A guide rail is convexly provided on the side of the rack away from the gear, and the guide rail and the slide groove are slidably matched. With such a design, the rack is supported by the bracket, which can effectively reduce the friction resistance encountered by the rack when sliding, thereby reducing the noise generated by friction or reducing the processing difficulty of the two contacting surfaces, and the sliding of the rack can be guided by the cooperation of the guide rail and the slide groove, so as to ensure that the rack can drive all the gears to rotate synchronously when sliding.

[0021] 6. The rack further includes a guide rod fixed on the first loading plate and a top plate installed at the top of the guide rod. The second loading plate is slidably installed on the guide rod. The driving component further includes a second air cylinder installed on the top plate. The second air cylinder includes a second telescopic rod connected to the second loading plate. When the second telescopic rod expands and contracts vertically, it drives the second loading plate to slide up and down, so as to drive the movable rod to lift and lower. With such a design, the second air cylinder can avoid various structures below the second loading plate, which is convenient for the disassembly, installation and maintenance of the second air cylinder.

[0022] 7. The cleaning structure further includes two sewage pipes. A sewage passage is formed inside the sewage pipes. Two rows of cleaning pipes are arranged between the two sewage pipes.

Detailed implementation manners

[0033] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0034] Refer to Figures 1 to 5 As shown, the filling device in this embodiment includes a frame, a cleaning structure, and two rows of filling valves arranged in parallel. Each row of filling valves includes a plurality of filling valves 100 arranged at intervals. The filling valve 100 is a diaphragm valve, so that small-dose filling of the medicament can be realized. The filling valve 100 has a feed inlet 110 and a discharge outlet 120. The frame includes a first carrier plate 200. Two rows of guide pipes 210 arranged in parallel are installed on the first carrier plate 200. The number of each row of guide pipes 210 is the same as the number of each row of filling valves 100, and the guide pipes 210 and the filling valves 100 are in one-to-one vertical correspondence. The guide pipes 210 penetrate through the first carrier plate 200. The filling valves 100 are installed on the top of the guide pipes 210, and the discharge outlet 120 is communicated with the inside of the guide pipes 210. In addition, two rows of cleaning pipes 220 are also provided on the first carrier plate 200. A cleaning pipe 220 is sleeved outside each guide pipe 210. The bottom end of the cleaning pipe 220 is lower than the bottom end of the guide pipe 210. A cleaning channel is formed between the cleaning pipe 220 and the guide pipe 210, and the cleaning channel is connected with a sewage channel.

[0035] The cleaning structure includes a driving component 300, a row of movable rods 400, and a sealing cover 500. The driving component 300 includes a first cylinder 310, a rack 320, and a row of gears 330. The rack 320 meshes with each gear 330. The machine frame further includes a second loading plate 600 disposed above the first loading plate 200. The first cylinder 310, the rack 320, and a row of gears 330 are all installed on the top surface of the second loading plate 600. The first cylinder 310 includes a first telescopic rod 311. A plurality of brackets 610 spaced along the length direction of the rack 320 are provided on the top surface of the second loading plate 600. A chute is provided on the bracket 610. One side of the rack 320 is provided with teeth that mesh with the gear 330, and a guide rail 321 protrudes from the side of the rack 320 facing away from the gear 330. The guide rail 321 is slidably engaged with the chute, thereby realizing the sliding installation of the rack 320 on the second loading plate 600. And this sliding installation method can not only effectively reduce the frictional resistance suffered by the rack 320 during sliding, thereby reducing the noise generated by friction or reducing the processing difficulty of the two contacting surfaces, but also realize the guiding of the sliding of the rack 320 through the cooperation of the guide rail 321 and the chute, so as to ensure that all the gears 330 can be driven to rotate synchronously when the rack 320 slides. One end of the first telescopic rod 311 is hinged to a connecting rod 340, and the other end of the connecting rod 340 is hinged to one end of the rack 320 close to the first cylinder 310. When the first cylinder 310 drives the first telescopic rod 311 to extend and retract along the length direction of the rack 320, the rack 320 can be driven to reciprocate through the connecting rod 340, thereby realizing the driving of the gear 330 to rotate.

[0036] A row of movable rods 400 is arranged between two rows of cleaning pipes 220. The number of movable rods 400 is the same as that of the single-row filling valves 100. The movable rods 400 penetrate through the first carrier plate 200 and the second carrier plate 600. Two of the above-mentioned plugging covers 500 which are symmetrically arranged are connected to the bottom of each movable rod 400. In order to enable the rotation of the movable rods 400, sleeves are also arranged on the outer sides of each movable rods 400. The sleeves are fixedly connected to the second carrier plate 600. The movable rods 400 can rotate relative to the sleeves and can also be axially fixed relative to the sleeves. A gear 330 is sleeved on the upper end of each movable rod 400. The part of the movable rod 400 that cooperates with the gear 330 is a non-circular shaft, so as to ensure that the gear 330 drives the movable rod 400 to rotate synchronously. In this way, when the first cylinder 310 drives the first telescopic rod 311 to extend and retract along the length direction of the rack 320, the rack 320 can be driven to reciprocate through the connecting rod 340, and then the rotation of the gear 330 is realized. The rotation of the gear 330 drives the rotation of the movable rod 400. In addition, the frame in this embodiment further includes a guide rod 700 and a top plate 800. The top of the guide rod 700 is fixedly connected to the top plate 800, and the bottom of the guide rod 700 is fixedly connected to the first carrier plate 200. Through holes for the guide rod 700 to penetrate are provided on the second carrier plate 600. The through holes are slidably matched with the guide rod 700, so that the second carrier plate 600 is slidably installed on the guide rod 700. The driving component further includes a second cylinder 350. The second cylinder 350 is installed on the top plate 800 and is located between the top plate 800 and the second carrier plate 600, so that various structures below the second carrier plate 600 can be avoided, which is convenient for the disassembly, installation and maintenance of the second cylinder 350. The second cylinder 350 includes a second telescopic rod. Four support columns 620 extending upward are further installed on the top surface of the second carrier plate 600. A connecting plate 630 is installed on the tops of the four support columns 620. The connecting plate 630 is located above the rack 320 and the gear 330. The second telescopic rod extends vertically, and the bottom end of the second telescopic rod is fixedly connected to the connecting plate 630. Thus, when the second cylinder 350 drives the second telescopic rod to extend and retract vertically, the second carrier plate 600 can be driven to slide up and down along the guide rod 700. Since the movable rod 400 is installed on the second carrier plate 600 through the sleeve, the up and down sliding of the second carrier plate 600 will drive the movable rod 400 to lift and lower synchronously.

[0037] When it is necessary to clean the filling valve 100 and the material guiding pipe 210, the first air cylinder 310 drives the first telescopic rod 311 to extend, so that the rack 320 slides in a direction away from the first air cylinder 310. The sliding of the rack 320 drives the gear 330 to drive the movable rod 400 to rotate synchronously, so that the sealing cover 500 rotates to directly below the corresponding cleaning pipe 220. Subsequently, the second air cylinder 350 drives the second telescopic rod to move upward and retract, so that the second carrier plate 600 drives the movable rod 400 to move upward, and the sealing cover 500 is in the first position. At this time, the sealing cover 500 seals the bottom end of the cleaning pipe 220. Then, a cleaning agent is added to the feeding port 110, and the cleaning agent for flushing the filling valve 100 enters the material guiding pipe 210 from the discharging port 120 and then flows to the cleaning channel and flows out through the sewage channel. When it is necessary to fill the container, the second air cylinder 350 drives the second telescopic rod to move downward and extend, so that the second carrier plate 600 drives the movable rod 400 to move downward. At this time, the sealing cover 500 is away from the bottom end of the cleaning pipe 220. Then, the first air cylinder 310 drives the first telescopic rod 311 to retract, so that the rack 320 slides in a direction close to the first air cylinder 310. The sliding of the rack 320 drives the gear 330 to drive the movable rod 400 to rotate synchronously and reverse to reset, so that the sealing cover 500 is in the second position (as Figure 2 shown), at this time, the sealing cover 500 is offset from the cleaning pipe 220 in the up and down direction, and the bottom ends of the two rows of cleaning pipes 220 and the bottom ends of the two rows of material guiding pipes 210 are all open. A container to be filled is placed below the cleaning pipe 220, and the material guiding pipe 210 can fill the container. It can be seen that in the filling device of the present invention, by changing the cleaning structure and the movement mode of the sealing cover 500, two rows of filling valves 100 can be installed on the frame, thereby increasing the number of filling valves 100 and improving the production efficiency.

[0038] In order to improve the sealing performance between the sealing cover 500 and the cleaning pipe 220 when the sealing cover 500 is in the first position to avoid leakage of the cleaning agent. In this embodiment, the sealing cover 500 is sleeved on the bottom end of the cleaning pipe 220. Preferably, the cleaning pipe 220 includes a matching section 221 that cooperates with the sealing cover 500, and the outer diameter of the matching section 221 gradually decreases from top to bottom. Such a design can facilitate the sealing cover 500 to be smoothly sleeved on the bottom end of the cleaning pipe 220.

[0039] In addition, for the convenience of separately cleaning the plugging cover 500 in the later stage, in this embodiment, an installation ring 900 is also sleeved outside the movable rod 400. A limiting shaft shoulder surface is provided on the outer peripheral side of the movable rod 400, and a threaded hole is provided at the bottom of the movable rod 400. The rod portion of the screw is locked in the threaded hole, and the installation ring 900 is clamped and fixed between the limiting shaft shoulder surface and the head of the screw, thereby realizing the detachable connection of the installation ring 900. An integral connection arm 910 is formed on the outer peripheral side of the installation ring 900, and the two plugging covers 500 are respectively installed on the two connection arms 910. In this way, when it is necessary to clean the plugging cover 500, the installation ring 900 can be detached from the movable rod 400.

[0040] Finally, in order to save the number of sewage discharge channels and the length of the corresponding pipelines, so as to simplify the structure of the filling device, the cleaning structure in this embodiment further includes two sewage pipes 1000. A sewage discharge channel is formed inside the sewage pipes 1000. Two rows of cleaning pipes 220 are arranged between the two sewage pipes 1000, and a sewage branch pipe 1100 is connected between each cleaning pipe 220 and the sewage pipe 1000 on the same side.

[0041] It can be understood that in other embodiments of the present invention, the second air cylinder may also be located below the second carrier plate, that is, the second air cylinder is installed on the first carrier plate, the top end of the second telescopic rod is connected to the second carrier plate, when the second air cylinder drives the second telescopic rod to extend, the second carrier plate drives the movable rod to rise, and when the second air cylinder drives the second telescopic rod to retract, the second carrier plate drives the movable rod to descend.

[0042] It can be understood that in other embodiments of the present invention, the end of the first telescopic rod may also be directly fixedly connected to the rack. With such a design, it can also be realized that when the first telescopic rod horizontally extends and retracts, it drives the rack to slide.

[0043] It can be understood that in other embodiments of the present invention, the plugging cover may also be an elastic flat plate structure. When the plugging cover is in the first position, the plugging cover forms a planar seal with the bottom end of the cleaning pipe.

[0044] It can be understood that in other embodiments of the present invention, one of the bottom surface of the rack and the top surface of the second carrier plate is provided with a sliding groove, and the other is provided with a guide rail that slidably cooperates with the sliding groove. With such a design, it can also be realized that the rack is slidably installed on the second carrier plate.

[0045] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
