Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, specifically to a material dispensing mechanism, filling equipment, and filling method. Background Technology

[0002] Filling machines are a subcategory of packaging machines. From the perspective of material packaging, they can be categorized into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines. In traditional production, product filling not only requires filling the product into containers but also sealing and inspecting the containers.

[0003] For feeding smaller containers, vibratory feeder is undoubtedly a very efficient feeding method. The vibratory feeder can discharge containers in an orderly manner. However, there is no gap between adjacent containers, which causes adjacent containers to stick together during vibratory feeder feeding. It can only be fed individually or in a row. Individual feeding is slow, while row feeding affects subsequent processes. The close proximity of adjacent containers will cause interference when picking up and placing adjacent containers for unqualified products, and it is also inconvenient to conduct product inspection. Although it improves the feeding efficiency, it will reduce the overall work efficiency.

[0004] Therefore, there is an urgent need for a material dispensing mechanism, filling equipment, and filling method to solve the problems existing in the current technology to a certain extent. Summary of the Invention

[0075] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application. Example

[0076] Combination Figures 1 to 22 As shown in the accompanying drawings, this embodiment provides a filling device. The connection relationship and principle of the various components of the filling device are described below with reference to the accompanying drawings. The automatic filling device includes a frame 1, a feeding vibratory plate 11 located on one side of the frame 1, and a material distribution mechanism 6, a material transfer module, a material flow structure 4, a filling module 8, a sealing and cutting module 9, and a detection module 10 located on the frame 1. The feeding vibratory plate 11 is used to provide containers 2 for holding the filling liquid. The material distribution mechanism 6 is used to arrange the containers 2 output by the feeding vibratory plate 11 in an orderly manner, so that there is a gap between adjacent containers 2. Multiple adjacent containers 2 can be arranged at equal intervals or according to other intervals. The material transfer module and the material flow structure 4 are used to sequentially transfer the liquid to the working area of ​​the filling module 8, the sealing and cutting module 9, and the detection module 10 to sequentially fill, seal, and detect leakage of the containers 2.

[0077] In this embodiment, the container 2 for holding the filling liquid is small in volume and weight. To prevent the container 2 from shifting when flowing between modules, this embodiment also includes a carrier 3 for carrying the container 2. The carrier 3 carries at least one set of containers 2, and in this embodiment, the container 2 can carry multiple sets of containers 2 simultaneously. The container 2 and the carrier 3 are involved in multiple processes of the filling equipment operation. For ease of subsequent description, the structures of the container 2 and the carrier 3 will be described separately here.

[0078] like Figure 1 As shown, container 2 is made of plastic material and includes a body portion 201 and a neck portion 202. The maximum distance between the outer walls of the body portion 201 is greater than the maximum distance between the outer walls of the neck portion 202, that is, the portion of the body portion 201 that extends beyond the neck portion 202 can form a barrier.

[0079] like Figures 2 to 6As shown, the carrier 3 includes a fixed base 301, a support plate 306, and a limiting component 307. The fixed base 301 has an opening at the bottom, through which the container 2 can pass. The support plate 306 is slidably mounted on the fixed base 301 and supports the container 2. The support plate 306 has a first clearance hole 3061 through which the container 2 can pass. The limiting component 307 is located above the support plate 306. It should be noted that the container 2 is placed above the bottom opening of the fixed base 301. The limiting component 307 prevents the container 2 from shifting horizontally relative to the carrier 3. When the support plate 306 slides until the first clearance hole 3061 coincides with the bottom opening of the fixed base 301, the container 2 can detach from the carrier 3. The limiting component 307 prevents the container 2 from being thrown off the carrier 3 during its movement. Moreover, unlike a clamping mechanism, the limiting component 307 does not cause the container 2 to deform under stress.

[0080] Specifically, the mounting base 301 includes a first mounting plate 3011 and a second mounting plate 302, with a third clearance hole 303 at a corresponding position on each. This third clearance hole 303 corresponds to the opening at the bottom of the mounting base 301. The second mounting plate 302 is located above the first mounting plate 3011. In this embodiment, the two are connected and fixed by bolts. Of course, the fixing method is not unique; it can also be bonding, integral molding welding, etc., which are not limited here. In this embodiment, the first mounting plate 3011 and the second mounting plate 302 are connected in a detachable manner to form the mounting base 301, rather than being fixed in a non-detachable manner. This way, if the mounting base 301 is partially damaged, only that part of the mounting base 301 can be replaced, which helps to save production costs.

[0081] Furthermore, the limiting component 307 includes a limiting plate 3071 and a limiting hole 3072 provided on the limiting plate 3071. The second mounting plate 302 includes a ladder 3024, and two sets of ladders 3024 are provided. The two sets of ladders 3024 are arranged parallel to each other at both ends of the second mounting plate 302, and the limiting plate 3071 and the ladder 3024 are connected by a first locking member. A sliding cavity is formed between the ladder 3024, the second mounting plate 302, and the limiting plate 3071. In order to avoid the limiting plate 3071 interfering with the bearing plate 306, the ladder 3024 is higher than the bearing plate 306. It should be emphasized that the height of the ladder 3024 is limited by the height of the container 2 to be loaded. The side of the limiting plate 3071 away from the second mounting plate 302 should be lower than the opening edge of the neck 202 of the container 2 to facilitate the clamping and sealing operation of the container 2.

[0082] Furthermore, the first locking element includes a first positioning bolt 3025 and a first positioning hole 3073. At least two sets of the first positioning bolts 3025 are provided, each located on the platform 3024. The first positioning hole 3073 is located at a corresponding position on the limiting plate 3071. After the first positioning hole 3073 and the first positioning bolt 3025 are aligned, the limiting plate 3071 is fastened onto the platform 3024. The first positioning hole 3073 and the first positioning bolt 3025 cooperate to prevent the limiting plate 3071 from shifting horizontally relative to the platform 3024. In other embodiments, the first locking element can also be a snap-fit ​​structure, or any structure capable of preventing the limiting plate 3071 from sliding relative to the platform 3024; no specific limitation is imposed.

[0083] In this embodiment, six sets of equidistant limiting holes 3072 are provided, meaning that each carrier 3 can simultaneously carry six sets of containers 2. Of course, the number of limiting holes 3072 and the distance between adjacent limiting holes 3072 can also be configured in other ways, depending on actual needs, and no additional restrictions are imposed here. Moreover, the first locking member in this embodiment has a simple structure and is relatively easy to operate, allowing the limiting plate 3071 to easily detach or engage with the ladder platform 3024. Therefore, different limiting plates 3071 can be easily replaced as needed, increasing the versatility of the carrier 3 and enabling it to be suitable for different loading requirements.

[0084] To achieve the unloading of container 2 by detaching it from the bottom of carrier 3, the following settings are made:

[0085] The second mounting plate 302 is provided with a first slide rail 304 and a first slider 305 slidably connected to the first slide rail 304. The bearing plate 306 is connected to the first slider 305. When the bearing plate 306 slides to the point where the openings at both ends of the first clearance hole 3061 coincide with the third clearance hole 303 and the limiting hole 3072 respectively, the container 2 can be detached from the bottom of the carrier 3, thereby completing the unloading of the container 2 relative to the carrier 3.

[0086] Furthermore, the second mounting plate 2302 also includes a first blocking part 3021 and a second blocking part 3022, which are disposed on both sides of the second mounting plate 302 extending along the sliding direction of the support plate 306. The first blocking part 3021 and the second blocking part 3022 can prevent the support plate 306 from sliding out of the second mounting plate 302. A third clearance opening 3023 is provided at the middle position of either the first blocking part 3021 or the second blocking part 3022. In this embodiment, the third clearance opening 3023 is opened in the second blocking part 3022. A push plate 3062 is provided on the support plate 306 at the position corresponding to the third clearance opening 3023. The push plate 3062 can pass through the third clearance opening 3023. The support plate 306 can slide relative to the second mounting plate 302 by pulling the push plate 3062, thereby realizing the position adjustment of the first clearance hole 3061 relative to the third clearance hole 303.

[0087] Furthermore, an elastic element 3027 and a positioning element 3028 are provided between the support plate 306 and either the first blocking part 3021 or the second blocking part 3022. The elastic element 3027 and the positioning element 3028 need to be located on the side away from the third clearance opening 3023. In this embodiment, the elastic element 3027 and the positioning element 3028 are located between the first blocking part 3021 and the support plate 306. When no force is applied to the support plate 306, one side of the support plate 306 abuts against the second blocking part 3022 under the elastic force of the elastic element 3027. When one side of the support plate 306 abuts against the second blocking part 3022, the first clearance hole 3061 deviates from the third clearance hole 303. When force is applied to the support plate 306, it compresses the elastic element 3027 until one side of the support plate 306 abuts against the positioning element 3028. At this time, the first clearance hole 3061 and the third clearance hole 303 can coincide. Specifically, in this embodiment, the elastic element 3027 is a compression spring, and the positioning element 3028 is a rod structure.

[0088] Preferably, the carrier 3 further includes a cover plate 308, which is fastened to a ladder 3024 above the second mounting plate 302. The cover plate 308 has a sixth clearance hole 3081 that allows the neck portion 202 to pass through. The sixth clearance hole 3081 is surrounded by a first clearance groove 3082 that is adapted to the body portion 201 of the container 2. The center distance between adjacent sixth clearance holes 3081 is equal to the center distance between adjacent limiting holes 3072. By providing the cover plate 308, the container 2 can be protected from damage. Especially during filling operations, the sixth clearance hole 3081 allows the filling operation to proceed normally, and the cover plate 308 can protect the container 2 from contamination by the filling liquid when it spills.

[0089] Specifically, the cover plate 308 is connected to the ladder platform 3024 via a second locking member. The second locking member includes a second positioning hole 3084 located diagonally on the cover plate 308 and a second positioning bolt 3026 located at a corresponding position on the ladder platform 3024. The second positioning hole 3084 and the second positioning bolt 3026 cooperate to prevent the cover plate 308 from shifting horizontally relative to the ladder platform 3024. A second clearance groove 3083 is provided on the side of the cover plate 308 near the ladder platform 3024. The shape of the second clearance groove 3083 is adapted to the shape of the limiting plate 3071, and the second clearance groove 3083 ensures that the cover plate 308 does not interfere with the limiting plate 3071 when it is fastened to the ladder platform 3024.

[0090] Furthermore, the carrier 3 also includes a locking block 3013, and the first mounting plate 3011 is provided with a locking groove 3012 that can cooperate with the locking block 3013. When installing the carrier 3, the locking block 3013 can be fixed first, and then the first mounting plate 3011 can be directly snapped onto the locking block 3013, which improves the convenience of installing the carrier 3; of course, the first mounting plate 23011 can also be connected to the installation station by welding, screwing or bonding.

[0091] like Figures 7 to 8 As shown, the material flow structure 4 includes a turntable 401 rotatably mounted on the frame 1 and a second driving component (not shown in the figure) that drives the turntable 401 to rotate. The turntable 401 is provided with an installation station for placing the carrier 3. The installation station is provided with a second clearance hole 402 that completely penetrates the turntable 401. When the carrier 3 is placed at the installation station, the third clearance hole 303 and the second clearance hole 402 coincide. The container 2 passes through the third clearance hole 303 and the second clearance hole 402 in sequence, thereby completing the unloading of the container 2 relative to the carrier 3. In this embodiment, the second driving component is a rotary motor. To improve processing efficiency, the turntable 401 in this embodiment is a four-section turntable 401, that is, four sets of carriers 3 can be set on one turntable 401 at the same time, so that the various processes of the filling equipment can be carried out simultaneously.

[0092] like Figure 9 and Figure 21 As shown, in order to ensure that the turntable 401 stops precisely at the preset work position and improve the processing accuracy, the filling equipment also includes a stop 5. The stop 5 is mounted on the frame 1. The stop 5 includes a third drive 501 and a top fixing plate 502 located at the output end of the third drive 501. The top fixing plate 502 is provided with a stop block 503. The turntable 401 is provided with a stop groove (not shown in the figure) on the side near the stop block 503. The stop block 503 can be inserted into the stop groove to stop the turntable 401.

[0093] Specifically, the stop groove can be located at any position on the turntable 401 near the side of the frame 1. The stop block 503 is positioned to accommodate the stop groove. However, when the stop groove is located on the turntable 401 below the mounting position of the carrier 3, to avoid interfering with the container 2's detachment from the carrier 3 and affecting subsequent processes of the container 2, a fourth clearance opening 504 is provided on the stop block 503 for the container 2 to pass through. After the container 2 detaches from the carrier 3, it passes through the second clearance hole 402 on the turntable 401 and then through the fourth clearance opening 504 on the stop block 503, thereby eliminating the interference of the turntable 401 and the stop block 503 on the container 2 and facilitating subsequent processing of the container 2. In this embodiment, the third driving component 501 is a cylinder, and two sets can be provided. The top fixing plate 502 is connected to the output end of the third driving component 501 respectively. The stop block 503 is positioned to avoid interference from the third driving component 501 with the container 2 passing through the fourth clearance opening 504.

[0094] like Figure 10-13 Referring to Figure 7, the material distribution mechanism 6 includes a first mounting base 601, a material storage channel 602, a material transfer component 603, a material distribution plate 604, and material distribution teeth 605. The first mounting base 601 is disposed on the frame 1, located between the feeding vibratory feeder 11 and the material flow structure 4. The material storage channel 602, the material transfer component 603, the material distribution plate 604, and the material distribution teeth 605 are respectively disposed on the first mounting base 601. The material transfer component 603 is used to transfer the containers 2 that slide out of the feeding vibratory feeder to the material storage channel 602 in sequence. The material distribution plate 604 and the material distribution teeth 605 are used to orderly distribute the containers 2 in the material storage channel 602.

[0095] Specifically, multiple sets of material separating teeth 605 are provided, all of which are mounted on a material separating plate 604. The material separating plate 604 is slidably mounted on the first mounting base 601, and both reciprocate within a preset stroke, which is a rectangular shape. The material separating mechanism 6 is used to separate and arrange the containers 2 that slide out of the feeding vibratory plate 11 at a certain interval. The distance between adjacent material separating teeth 605 determines the distance between adjacent containers 2. By creating a distance between adjacent containers 2, it is possible to prevent adjacent containers 2 from piling up together, which would affect the feeding of containers 2 and subsequent inspection. In this embodiment, the material separating teeth 605 are evenly spaced on the material separating plate 604. The material separating plate 604 and the material separating teeth 605 cooperate to arrange adjacent containers 2 at equal distances within the material storage channel 602, which facilitates subsequent processing and improves work efficiency.

[0096] The container 2 that first enters the storage channel 602 is located at the first station. As the distribution plate 604 moves, the first distribution tooth 605 near the feeding vibrating plate pushes the container 2 from the first station to the second station, which is adjacent to the first station. Then, the second container 2 that enters the storage channel 602 is initially located at the first station. The distribution tooth 605 and the distribution plate 604 push the container 2 from the first station to the second station by the first distribution tooth 605. At the same time, the container 2 that was originally located at the second station is pushed to the third station by the second distribution tooth 605 next to the first distribution tooth 605. The above operation is repeated until the storage channel 602 is filled with adjacent containers 2 at equal distances.

[0097] Preferably, the material transfer assembly 603 includes a material guide channel 6031 disposed on the first mounting base 601, a pusher block 6032 slidably disposed in the material guide channel 6031, and a first driving member 6033 disposed on the first mounting base 601 and cooperating with the pusher block 6032. The output end of the feeding vibratory plate abuts against the side wall of the material guide channel 6031. The material guide channel 6031 is provided with a first clearance opening 606 for the container 2 to pass through. One end of the material guide channel 6031 abuts against the side wall of the storage channel 602. The storage channel 602 is provided with a second clearance opening 607 for the container 2 to pass through at the abutment position of the material guide channel 6031. The working process of the material transfer component 603 is as follows: the container 2 in the feeding vibratory feeder passes through the first clearance port 606 and enters the material guide channel 6031. The first driving member 6033 drives the pusher block 6032 to slide, thereby causing the pusher block 6032 to push the container 2 through the second clearance port 607 and enter the storage channel 602. In this embodiment, the first driving member 6033 can be a telescopic cylinder, or it can be a lead screw structure, or other structures that can push the pusher block 6032 to reciprocate.

[0098] To prevent the container 2 from shifting during the pushing process of the pusher 6032, the pusher 6032 includes a limiting groove, which is located at the end of the pusher 6032 away from the first driving member 6033. Guide extension plates are provided on both sides of the limiting groove so that the container 2 enters the limiting groove during the forward movement of the pusher 6032.

[0099] Furthermore, the material distribution plate 604 is driven to move on the first mounting base 601 by the material distribution plate driving component 608. In this embodiment, the composition and connection relationship of the material distribution plate driving component 608 are as follows: The material distribution plate driving component 608 includes a first shaft plate 6081, a second shaft plate 6082, and an eighth driving component 6083. The first shaft plate 6081 is slidably connected to the first mounting base 601 through a second slide rail and a second slider. The second shaft plate 6082 is slidably connected to the first shaft plate 6081 through a third slide rail 6084 and a third slider 6085. The material distribution plate 604 and the second shaft plate 6082 are detachably connected, which facilitates the replacement of the material distribution plate 604 according to the distance requirements between different containers 2, increasing the versatility of the material distribution module. The sliding direction of the first shaft plate 6081 is perpendicular to the sliding direction of the second shaft plate 6082, and the sliding direction of the first shaft plate 6081 is perpendicular to the length extension direction of the material storage channel 602. A rotating rod 6086 is provided on the first mounting base 601. The rotating rod 6086 is slidably connected to the first mounting base 601. The sliding stroke trajectory of the rotating rod 6086 is formed as a "rounded rectangle" (a "rectangle" with rounded corners on all four sides). A bearing is provided on the rod body of the rotating rod 6086. The output end of the rotating rod 6086 is connected to the material distribution plate 604. A first elongated groove 6087 is provided on the first shaft plate 6081, through which the rotating rod 6086 passes. The lower part of the first mounting base 601 is a hollow structure, forming an installation space. The eighth driving member 6083 is located inside the installation space. The output end of the eighth driving member 6083 passes through the upper end surface of the first mounting base 601. A connecting block 6088 is provided at the output end of the eighth driving member 6083. A second elongated groove 6089 is provided on the connecting block 6088, through which the rotating rod 6086 passes. In this embodiment, the eighth driving component 6083 is a rotary motor, the output shaft of the fifth rotary motor drives the connecting plate to rotate, and the second elongated groove 6089 on the connecting block 6088 cooperates with the rotating shaft to drive the rotating shaft to slide along a preset stroke.

[0100] After the material distribution is completed, the first material transfer module 71 transfers the container 2 to the carrier 3 located on the turntable 401. Figure 14 And see Figure 7As shown, the first material transfer module 71 includes a robot 711, a gripping assembly 712, and a suction cup assembly 713 connected to each other. The robot 711 is mounted on the frame 1, and the gripping assembly 712 and suction cup assembly 713 are located at the output end of the robot 711. Multiple gripping assemblies 712 can be provided, which are used to pick up and place containers 2. The suction cup assembly 713 is based on the structure of the carrier 3 and is used to pick up and place the cover plate 308. The robot 711 can drive the gripping assembly 712 to grip the container 2 from the material flow channel 602 and transfer it to the empty carrier 3 of the turntable 401. After the container 2 is placed on the carrier 3, the robot 711 can drive the suction cup assembly 713 to remove or fasten the cover plate 308 from the second mounting plate 302. During operation, the gripping component 712 picks up the container 2 in the storage channel 602 and moves it to the position of the carrier 3. The suction cup component 713 first removes the cover plate 308. The gripping component 712 moves to the top of the carrier 3 under the drive of the robot 711, so that the container 2 corresponds to the limiting hole 3072 of the carrier 3. The gripping component 712 releases the container 2, and then the robot 711 and the suction cup component 713 fasten the cover plate 38 to the second mounting plate 302.

[0101] Furthermore, the gripping assembly 712 includes a mounting plate 7122 connected to the output end of the robot 711, a picking plate 7128 connected to the mounting plate 7122, and a first gripper mechanism disposed on the picking plate 7128. The first gripper mechanism includes a first gripper portion 7121 fixedly connected to the picking plate 7128, a second gripper portion 7123 slidably connected to the picking plate 7128 and cooperating with the first gripper portion 7121, and a gripper drive member 7124 driving the second gripper portion 7123 to slide. Multiple sets of the first gripper portion 7121 and the second gripper portion 7123 are correspondingly provided. In this embodiment, the gripper drive member 7124 is a cylinder; however, in other embodiments, it can also be an electric telescopic rod or other structures, which are not limited here.

[0102] Furthermore, the gripping assembly 712 also includes a gripper mounting plate 7125 for mounting the second gripper portion 7123. The gripper mounting plate 7125 is slidably connected to the picking plate 7128 via a fourth slide rail 7126 and a fourth slider 7127. The gripper drive member 7124 drives the gripper mounting plate 7125 to slide, thereby enabling the second gripper portion 7123 to slide towards or away from the first gripper portion 7121, thus enabling the gripping or release of the container 2.

[0103] It should be emphasized that there is a gap between the suction cup assembly 713 and the gripping assembly 712, and the carrier 3 is higher than the turntable 401. When either the suction cup assembly 713 or the gripping assembly 712 is located on the carrier 3 to pick up or put down the cover plate 308 or release the container 2, the suction cup assembly 713 and the gripping assembly 712 will not interfere with each other.

[0104] After placing container 2 onto carrier 3, the basic loading process is complete. Turntable 401 then rotates carrier 3, which carries container 2, to filling module 8 for the filling operation. Figures 8 to 9 As shown, the filling module 8 includes a support frame 801, a sixth driving component 802, and an injection needle 803. The sixth driving component 802 drives the injection needle 803 to slide along the X and Z directions (X and Z directions are...). Figure 8 (As shown in the diagram), the injection needle 803 slides to the corresponding container 2 for filling. The input end of the injection needle 803 is connected to the injection pump 804 via a connecting pipe (not shown in the diagram), and the injection pump 804 can be mounted on the frame 1. Of course, other liquid supply structures can also be used, as long as they can accurately inject liquid, without specific limitations. The fifth drive component 9072 is an existing mature technology and will not be described in detail here.

[0105] Furthermore, a detachable recycling bin 805 with an upper opening is mounted on the support frame 801 to prevent filling liquid from dripping from the injection needle 803 onto the frame 1, thus avoiding waste and pollution of the working environment. The recycling bin 805 and the support frame 801 can be detachably connected or fixedly connected. However, in the fixed connection, a valve and a discharge pipe are required to facilitate the drainage of the filling liquid from the recycling bin 805. In this embodiment, the recycling bin 805 and the support frame 801 are connected by a snap-fit ​​mechanism. The opening of the recycling bin 805 is provided with a supporting step 806, and the support frame 801 is provided with a supporting plate 807 with an opening. After the body of the recycling bin 805 passes through the opening, the upper edge of the opening blocks the supporting step 806, causing the recycling bin 805 to be snapped onto the supporting plate 807.

[0106] After the container 2 has been filled, it needs to be sealed. The turntable 401 rotates the carrier 3 carrying the filled container 2 into the working area of ​​the sealing and cutting module 9. Figures 15-18 And see Figure 7As shown, the sealing and cutting module 9 includes a feeding roll 901, a take-up roll 902, a film pressing assembly 905, a hot-melt assembly 907, and a punching assembly 906. Two parallel columns 903 are mounted on the frame 1, and a fixed platform 904 is erected between the two columns 903. The fixed platform 904 is used to house the sealing and cutting module 9. The feeding roll 901 and the take-up roll 902 are positioned above the fixed platform 904. The fixed platform 904 has an opening for the film material to pass through. The feeding roll 901 is wound with the film material to be used, and the take-up roll 902 is used to collect the used film material scraps. The feeding roll 901 and the take-up roll 902 work together to ensure the film material moves forward in an orderly manner. It is important to emphasize that the feeding speed of the feeding roll 901 and the take-up speed of the take-up roll 902 are the same, allowing the film material to be continuously conveyed under tension. The film pressing assembly 905 is used to press and fix the film material, the hot melt assembly 907 is used to heat the film material so that the film material is bonded to the neck edge of the container 2, and the film punching assembly 906 is used to separate the film material inside the neck edge of the container 2 from the film material outside the neck edge.

[0107] Specifically, such as Figure 18 As shown, the film pressing assembly 905 includes a lower pressure plate 9051, a film pressing pad 9052, a seventh driving member 9054, and an antistatic foam 9053. The seventh driving member 9054 is mounted on a mounting rib 9055 on a fixed platform 904. The lower pressure plate 9051 is located at the output end of the seventh driving member 9054. Under the drive of the seventh driving member 9054, the lower pressure plate 9051 can slide along a direction perpendicular to the upper surface of the fixed platform 904. The film pressing pad 9052 is located below the lower pressure plate 9051, and the two are fixedly connected. The antistatic foam 9053 is fixed by two side plates on the lower pressure plate 9051. The film material can pass between the film pressing pad 9052 and the antistatic foam 9053. The lower pressure plate 9051, the film pressing pad 9052, and the antistatic foam 9053 are provided with fourth clearance holes 9056 at corresponding positions, through which the output ends of the heat-melting assembly 907 and the film-punching assembly 906 pass. In this embodiment, the seventh driving component 9054 is a cylinder. In other embodiments, the seventh driving component 9054 can also be a screw structure, an electric telescopic rod, or other structures. The driving component of the lower pressure plate 9051 drives the lower pressure plate 9051 and the film pressing pad 9052 to slide towards the antistatic foam 9053, until the film material is pressed between the film pressing pad 9052 and the antistatic foam 9053. After the film material is pressed tightly, the heat-melting assembly 907 and the film-punching assembly 906 process the film material in sequence to complete the sealing of the container 2.

[0108] like Figure 17As shown, the hot melt assembly 907 includes a hot melt head 9071 and a fifth driving member 9072 that drives the hot melt head 9071 to slide in a direction parallel to the upper surface of the fixed platform 904 and in a direction perpendicular to the upper surface of the fixed platform 904, respectively. The fifth driving member 9072 is disposed on the fixed platform 904. The fifth driving member 9072 is a conventional setting in the prior art and will not be described in detail here.

[0109] Furthermore, the hot melt assembly 907 also includes a second mounting base 9073, and a hot melt head 9071 is disposed on the second mounting base 9073. The center distance between adjacent hot melt heads 9071 is the same as the center distance between adjacent containers 2 in the material storage channel 602. A heat insulation plate 9074 is provided on the side of the second mounting base 9073 connected to the output end of the fifth drive member 9072. The hot melt head 9071 is disposed on the side of the second mounting base 9073 away from the heat insulation plate 9074. The hot melt head 9071 is heated by a thermocouple 9075 disposed on the second mounting base 9073.

[0110] Furthermore, the heating end of the hot melt head 9071 is a ring structure with a central slot. The diameter of the hot melt head 9071 is the same as the outer diameter of the neck of the container 2. The slot is a cylindrical structure with the same diameter as the inner diameter of the neck of the container 2. The part of the film material in contact with the container 2 is precisely focused and heated, so that the film material adheres to the edge of the neck 202 of the container 2, protecting the non-contacting parts from being damaged by heat.

[0111] Furthermore, a protective plate 9076 is provided on the second mounting base 9073 at the end where the hot-melt head 9071 is mounted. The protective plate 9076 is connected to the second mounting base 9073 by a compression spring 9077. The protective plate 9076 can be moved closer to or away from the second mounting base 9073 by compressing the compression spring 9077. The protective plate 9076 is provided with a fifth clearance hole 9078 that allows the hot-melt head 9071 to pass through. Without applying force to the protective plate 9076, the hot-melt head 9071 will not protrude from the fifth clearance hole 9078 on the protective plate 9076. The protective plate 9076 can protect the internal structure of the automatic filling equipment. When the hot-melt head 9071 is not working, the protective plate 9076 can prevent personnel or the internal structure of the automatic filling equipment from touching the hot-melt head 9071 and being damaged. Moreover, when working, the protective plate 9076 and the compression spring 9077 can buffer the impact force of the hot-melt head 9071 on the container 2.

[0112] Furthermore, the die assembly includes a punch 9061, a punch 9061 mounting plate 7122 connecting the punch 9061, and a ninth driving member 9062 that drives the punch 9061 mounting plate 7122 to move up and down. The ninth driving member 9062 is mounted on a fixed platform 904, and its output end is connected to the punch 9061 mounting plate 7122. The punch 9061 is mounted on the punch 9061 mounting plate 7122. The center distance between adjacent punches 9061 is the same as the center distance between adjacent hot melt heads 9071, and the diameter of the punch 9061 is the same as the outer diameter of the neck of the container 2. The punch 9061 applies force to the film material, causing the film material to be cut off along the outer edge of the neck portion 202. In this embodiment, the ninth driving member 9062 is a cylinder, but it is not limited to a cylinder; in other embodiments, it can also be other power structures.

[0113] Furthermore, the sealing and cutting module 9 also includes a film adjusting assembly (not shown in the figure) and a material handling component. The film adjusting assembly is used to adjust the transmission direction and position of the film material between the unloading roll 901 and the take-up roll 902, so that it can cooperate with the sealing work of the container 2, reduce the space constraint on the film material, and change its direction or working position. In the embodiment, the film adjusting assembly is a multi-set rotating roller structure, which will not be described in detail here. The material handling component is used to smooth the flatness of the film material and avoid wrinkles in the film material. The material handling component includes parallel rotating rollers, through which the film material passes and abuts against the two rotating rollers respectively.

[0114] After filling and sealing, container 2 needs to be transferred to carrier tray 106 using the second transfer module 72 and the third transfer module 73. For example... Figure 19 and Figure 20 As shown, the second material transfer module 72 includes a transfer mechanism 721 and a flipping structure. The transfer mechanism 721 is used to transfer the container 2 on the carrier 3, and the flipping structure is used to flip the container 2 at the transfer mechanism 721 by 180 degrees so that the bottom of the container 2 faces upward.

[0115] Specifically, such as Figure 14 As shown, the transfer mechanism 721 includes a receiving plate 7211 and a fourth driving member 7213 that cooperates with the receiving plate 7211. The receiving plate 7211 has a receiving cavity 7212 for holding the container 2. The center-to-center distance between adjacent receiving cavities 7212 is the same as the center-to-center distance between adjacent containers 2 on the carrier 3, and the height of the receiving cavity 7212 is less than that of the container 2. The container body 201 of the container 2 is higher than the receiving cavity 7212. The fourth driving member 7213 is provided in the mechanism and can drive the receiving plate 7211 to slide along the X direction and the Z direction, respectively. The X direction and the Z direction are adjacent to the container body 2. Figure 19 The direction indicated in the diagram is as follows: the fourth drive unit 7213 uses a conventional drive method, which will not be described further here.

[0116] The receiving plate 7211 includes a main body 201 and a blocking part located below the main body 201. The main body 201 can pass through the third clearance hole 303, and the blocking part abuts against the turntable 401. The bearing cavity corresponds one-to-one with the limiting hole 3072.

[0117] The fourth driving component 7213 first drives the receiving plate 7211 to move to the stop 5. The container 2 on the carrier 3 has completed the filling and sealing work. The fourth driving component 7213 then drives the receiving plate 7211 to move closer to the turntable 401 until the receiving plate 7211 abuts against the first mounting plate 3011 of the carrier 3, pushing the push plate 3062 of the bearing plate 306 so that the container 2 falls into the receiving cavity 7212.

[0118] Furthermore, to improve the level of automation, such as Figure 9 As shown, the automatic filling equipment also includes a top plate mechanism 12, which is mounted on the frame 1 and is used to drive the support plate 306 to slide along the second mounting plate 302, so that the container 2 can automatically detach from the carrier 3. The top plate mechanism 12 includes an L-shaped top plate 121, a rodless cylinder 122 that drives the top plate to slide in the X direction, and a slide cylinder 123 connected to the output end of the rodless cylinder 122 that drives the top plate 121 to slide in the Y direction. The top plate 121 is located at the output end of the slide cylinder 123. The rodless cylinder 122 drives the top plate 121 to slide towards the turntable 401 to the carrier 3 where the container 2 needs to be unloaded. The push plate 3062 is on the same horizontal line as the top plate. The slide cylinder 123 extends to apply force to the push plate 3062. After the container 2 detaches from the carrier 3, the top plate mechanism 12 resets.

[0119] Specifically, such as Figure 20 As shown, the flipping mechanism 722 includes a bracket mounted on the frame 1, a flipping clamp 7221 rotatably connected to the bracket, a rotary motor 7222 driving the flipping clamp 7221 to rotate, and a second gripper mechanism 7223 connected to the flipping clamp 7221. The second gripper mechanism 7223 is the same as the first gripper mechanism, and will not be described in detail again. It should be emphasized that, in order to avoid interference between the flipping mechanism 722 and the receiving plate 7211 during operation, the driving structure of the receiving plate 7211 drives the receiving plate 7211 to move downward when the flipping mechanism 722 is working.

[0120] See Figure 7 As shown, the third transfer module 73 is mounted on the frame 1 and is used to transfer the container 2 at the flipping mechanism 722 to the carrier tray 106. The third transfer module 73 does not have the suction cup assembly 713 compared to the first transfer module 71, but the rest of the structure is the same, and will not be described in detail here.

[0121] like Figure 7As shown, the detection module 10 is used to detect whether the container 2, after filling and sealing, is leaking. The colorimetric test strip is cut and placed on the carrier tray 106. The colorimetric test strip can react with the filling liquid. The container 2 is placed upside down in the carrier tray 106, and the color change of the colorimetric test strip can be used to determine whether the container 2 is leaking.

[0122] Furthermore, the carrier tray 106 is slidably mounted on the frame 1 via the fourth slide rail 7126 and the fourth slider 7127. The carrier tray 106 and the fourth slider 7127 are detachably connected, facilitating unloading or replacement of the carrier tray 106. The carrier tray 106 is provided with a placement cavity 107, and the spacing between adjacent placement cavities 107 is the same as the spacing between adjacent containers 2 on the carrier 3.

[0123] Specifically, see Figure 7 and Figure 22 The testing module 10 includes a gantry support 101, a feeding group 102, a receiving group 103, a stamping group 104, and a transverse movement module 105 mounted on the gantry support 101. The gantry support 101 is mounted on the frame 1 and has a sliding mounting plate 7122. The feeding group 102, the receiving group 103, and the stamping group 104 are mounted on the sliding mounting plate 7122. The transverse movement module 105 can drive the sliding mounting plate to slide along the crossbeam of the gantry support 101. The feeding group 102, the receiving group 103, and the transverse movement module 105 are conventional technologies and will not be described in detail here. The stamping group includes a stamping part 104 and a pressing part 108. The pressing part 108 presses down the colorimetric test paper, and the stamping part 104 divides the colorimetric test paper into several equal parts, which fall into the placement cavity 107 of the carrier tray 106 under the action of gravity.

[0124] Further, the stamping section 104 includes a stamping cylinder 1041 disposed on the sliding mounting plate 7122, a stamping plate 1042 connected to the output end of the stamping cylinder 1041, and a stamping rod 1043 connected to the stamping plate 1042. The center distance between adjacent stamping rods 1043 is the same as the center distance between adjacent placement cavities 107, and the center distance between adjacent placement cavities 107 is the same as the center distance between adjacent containers 2 on the material storage channel 602. The pressing section 108 is disposed below the stamping section 104, and includes a first pressing plate 1081 and a second pressing plate 1082. The second pressing plate 1082 is provided with a limiting bolt that restricts the first pressing plate 1081 from moving in the horizontal direction.

The pressing part 108 is provided with a punching hole 1083 through which the punching rod 1043 passes.

[0125] Preferably, the frame 1 is provided with a cover, which is equipped with buttons, a display screen and ventilation holes. The bottom of the frame 1 is provided with casters 1012 to facilitate the movement of the filling equipment. A height-adjustable foot cup 1011 is provided close to the casters 1012. When not moving, the foot cup 1011 is lowered to contact the ground to increase the stability of the filling equipment.

[0126] This application provides a filling method using the filling equipment of one embodiment, comprising the following steps:

[0127] Step 1: Start the feeding vibratory feeder 11 to continuously output material. The feeding vibratory feeder 11 separates the containers 2 output by the feeding vibratory feeder 11 through the material distribution mechanism 6, so that there is a gap between adjacent containers 2. In this embodiment, the gap size is the same.

[0128] Step 2: The first material transfer module 71 can pick up and deliver multiple sets of containers 2, which are neatly stacked by the material distribution mechanism 6, to the carrier 3 located on the turntable 401 in one go. The turntable 401 rotates and drives the containers 2 to pass through the filling module 8 and the sealing and cutting module 9 in sequence for liquid injection and sealing. The turntable 401 drives the carrier 3 to rotate by its own rotation, so that the carrier 3 can be used in a closed loop. The feeding, filling and sealing operations can be carried out simultaneously, which helps to improve work efficiency.

[0129] Step 3: The second transfer module 72 is activated to remove the container 2 after liquid injection and sealing and rotate it 180 degrees. The third transfer module 73 then transfers the inverted container 2 to the working area of ​​the detection module 10 to check for leakage. During the process, the container 2 is placed upside down in the carrier tray 106 containing the colorimetric test paper, and the carrier tray 106 is removed together with the container 2 during the unloading process. This allows the container 2 to be in contact with the colorimetric test paper in the carrier tray 106 for a long time, which can detect containers with serious leakage as well as containers with slight leakage.

[0130] In this filling method, the containers 2 output by the feeding vibratory plate 11 are orderly divided before the feeding operation, so that there is a gap between adjacent containers 2. This allows multiple sets of containers 2 to be fed at one time, resulting in high filling efficiency and no impact on the subsequent processing of containers 2 by the workpiece. Especially when it comes to leakage detection, it ensures that there is no interference between adjacent containers 2, and the detection accuracy is high.

[0131] The above description is only a preferred embodiment of the material dispensing mechanism, filling equipment and filling method disclosed in this invention. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
