Description

Technical Field

[0001] This invention relates to the field of filling technology, and in particular to a dual-row high-speed filling machine and its filling method. Background Technology

[0002] In the field of filling technology, high-speed filling machines are the core equipment for the automated filling and sealing of containers such as stand-up pouches. The structural design of its container conveying device directly determines the production efficiency and operational stability of the entire machine.

[0003] Current filling machines connect the bag feeding mechanism with the turntable to achieve automatic conveying and intermittent transmission of stand-up pouches. The turntable is divided into a fixed plate and a rotating plate. The edge of the rotating plate is equipped with a slot to hold the mouth of the stand-up pouch. The fixed plate is used to install filling valves, capping mechanisms, etc. Existing filling machines reduce labor intensity and improve work efficiency to a certain extent.

[0004] However, existing filling machines still suffer from significant efficiency bottlenecks in their container conveying devices. On the one hand, the turntable, as the core conveying component, has only one ring of container slots evenly arranged around its perimeter. Limited by the outer diameter of the turntable and the layout of the mechanical structure, the number of slots in a single ring is limited, and the number of stand-up pouches that can be received and conveyed per unit time is strictly limited. On the other hand, the conveying system generally adopts a single guide rail design, which can only realize the sequential conveying of a single group of stand-up pouches. Containers need to queue along a single guide rail to wait for the single ring of slots on the turntable. Even if the efficiency is improved by increasing the turntable speed, it is easy to affect the continuity of production due to problems such as mechanical overload and decreased container positioning accuracy.

[0005] The aforementioned structural defects have made it difficult for existing high-speed filling machines to break through the bottleneck in filling efficiency. The combination of a single-ring slot and a single guide rail means that the container throughput per unit time cannot meet the high capacity requirements of large-scale production scenarios. In addition, existing filling machines cannot achieve parallel operation of the entire process of filling, cleaning, capping, and bag removal, which restricts the improvement of production efficiency in the filling technology industry. Therefore, there is an urgent need for a technical solution that can break through the existing structural limitations and significantly improve the efficiency of conveying and filling. Summary of the Invention

[0006] The purpose of this invention is to provide a dual-row high-speed filling machine and its filling method to overcome the problem that existing filling machines can only clamp in a single layer, resulting in low conveying and filling efficiency.

[0007] In a first aspect, the present invention also provides a high-speed filling machine, which adopts the following technical solution:

[0008] 1. A high-speed filling machine, characterized in that it includes a first bag storage mechanism, a second bag storage mechanism, a first bag feeding mechanism, a second bag feeding mechanism, a turntable mechanism, a filling mechanism, a cleaning mechanism, a capping mechanism, and a bag ejection mechanism;

[0009] The turntable mechanism includes a fixed plate, a turntable, a driving device, and a separating device; the driving device is used to drive the turntable to rotate around its own axis; the outer periphery of the turntable is uniformly provided with a plurality of elongated slots along the circumferential direction; the separating device is located above the middle of the slot, and its orthographic projection divides the slot below it into an inner ring engagement part and an outer ring engagement part.

[0010] On the same side of the turntable, the first bag feeding mechanism and the second bag feeding mechanism are arranged in parallel and opposite to each other, while the first bag storage mechanism and the second bag storage mechanism are arranged opposite to each other and are respectively connected to the feeding end of the first bag feeding mechanism and the second bag feeding mechanism.

[0011] The outlet end of the first bag feeding mechanism is located in front of the separating device and is used to feed the container into the inner ring locking part; the outlet end of the second bag feeding mechanism is located in front of the separating device and is used to feed the container into the outer ring locking part.

[0012] The starting end of the separating device is adjacent to the rear of the first bag feeding mechanism, and its end extends to the front of the bag unloading mechanism.

[0013] The filling mechanism, cleaning mechanism, capping mechanism, and bag ejection mechanism are arranged sequentially around the turntable along the rotation direction of the turntable. The filling mechanism and cleaning mechanism are located on the upper half of the fixed plate, and the capping mechanism and bag ejection mechanism are located on the lower half of the fixed plate.

[0014] The filling mechanism includes four to twelve sets of filling nozzles, each set of filling nozzles consisting of a filling nozzle facing the inner ring locking part and a filling nozzle facing the outer ring locking part;

[0015] The cleaning mechanism includes several sets of cleaning heads. Each set of cleaning heads consists of a cleaning head facing the inner ring snap-fit ​​part and a cleaning head facing the outer ring snap-fit ​​part. The number of cleaning heads is the same as the number of filling nozzles.

[0016] A cap feeding machine is provided between the cleaning mechanism and the capping mechanism. The capping mechanism includes several sets of capping heads. Each set of capping heads consists of a capping head facing the inner ring locking part and a capping head facing the outer ring locking part. The number of capping heads is the same as the number of filling nozzles.

[0017] The bag ejection mechanism includes a number of bag ejection cylinders, the number of which is equal to the number of filling nozzles.

[0018] When the filling mechanism is in operation, the cleaning mechanism, the capping mechanism, and the bag ejection mechanism operate simultaneously.

[0019] The cleaning mechanism, cap sorting machine, cap screwing mechanism and bag ejection mechanism mentioned above are existing technologies and will not be described in detail here.

[0020] Preferably, the dividing device in front of the second bag feeding mechanism is inclined towards the outer edge of the turntable to form a guide section.

[0021] Preferably, a protective part is also provided above the turntable. The protective part is located outside the separating device and is used to prevent the container contained in the outer ring locking part from accidentally falling out when the turntable rotates.

[0022] Preferably, the protective part is located behind the outlet end of the second bag feeding mechanism, and the end of the protective part corresponds to the end of the separating device.

[0023] Preferably, the first and second storage bag mechanisms include a batch-carrying component and a driving component; the batch-carrying component is used to simultaneously carry multiple containers arranged in parallel to form a container row; the driving component is connected to the batch-carrying component and is used to drive the batch-carrying component to move stepwise along a preset path.

[0024] Preferably, the first bag feeding mechanism and the second bag feeding mechanism include a clamping and transferring component and a separating and pushing component; the clamping and transferring component is used to move the batch carrying component on the first bag storage mechanism or the second bag storage mechanism to the first bag feeding mechanism or the second bag feeding mechanism; the separating and pushing component is used to separate the container from the batch carrying component onto the slide rail of the first bag feeding mechanism or the second bag feeding mechanism and transport it in the direction of the turntable.

[0025] Secondly, the present invention also provides a dual-row high-speed filling method, comprising the following steps:

[0026] S1: The first and second bag storage mechanisms, which are set opposite to each other, store containers respectively and transport the containers to the feeding ends of the first and second bag feeding mechanisms arranged in parallel, so as to complete the pre-supply of double-row containers and prepare for subsequent double-row synchronous loading.

[0027] S2: The turntable is evenly provided with several long strip-shaped slots along its circumference. The angle between the center lines of two adjacent slots is α. The angle between the lines connecting the center of the first bag feeding mechanism outlet end and the center of the second bag feeding mechanism outlet end to the center of the turntable is an integer multiple of the slot angle α, ensuring that the bag feeding station is accurately aligned with the slot.

[0028] The turntable rotates intermittently, pausing after each rotation by an angle α; within each pause cycle:

[0029] The first bag feeding mechanism pushes a first container into an empty slot. After being guided by the separating device, the first container enters the inner ring engaging part of the slot, thus completing the loading of the first container in the slot.

[0030] The slot with the first container loaded continues to rotate with the turntable. When the slot moves to the corresponding station of the second bag feeding mechanism, during the subsequent pause cycle, the second bag feeding mechanism pushes a second container into the outside of the same slot. The second container is positioned and clamped by the outer protective part of the slot, forming a set of double-layer clamped containers to be filled.

[0031] The above loading action is repeated cyclically. A transportation cycle is completed when M consecutive sets of slots on the turntable complete double-layer clamping, where M is an integer from 6 to 10.

[0032] S3: The turntable rotates by an angle Mα every interval, which means that the M groups of containers that have been loaded are transferred to the filling station as a whole; after the turntable stops, the filling mechanism fills the 2M containers located at the filling station with materials simultaneously through 2M filling nozzles.

[0033] S4: After one transportation cycle, the turntable rotates intermittently by an angle Mα to transfer the M groups of containers that have been filled to the cleaning station. After the turntable stops, the cleaning mechanism uses 2M cleaning heads to simultaneously clean the nozzles of the M groups of containers to remove residual materials from the nozzles.

[0034] S5: During one transport cycle, the turntable rotates intermittently by an angle Mα, sequentially transferring the cleaned M groups of containers through the corresponding station of the cap sorting machine; the turntable pauses once every time it rotates by an angle α, and the cap sorting machine simultaneously supplies caps to the container mouths of a group of containers;

[0035] S6: After one transportation cycle, the turntable rotates intermittently by an angle Mα to transfer the M groups of containers equipped with caps to the capping mechanism. The capping mechanism uses 2M capping heads to simultaneously cap and seal the M groups of containers located at the capping station.

[0036] S7: After one transportation cycle, the turntable rotates intermittently by an angle Mα, transferring the M groups of containers with completed capping to the bag removal station; the bag removal mechanism simultaneously removes the first and second containers from the M groups of containers from the inside and outside of the slots, respectively, to complete the collection of finished containers;

[0037] The above steps are repeated. During the pause after the turntable rotates by an angle Mα, each station simultaneously performs filling, cleaning, capping, and bag removal on the container group currently located at its station, achieving continuous and efficient filling under parallel operation throughout the entire process.

[0038] This invention has at least one of the following beneficial effects:

[0039] 1. This invention, through its innovative double-layer clamping structure and matching double bag feeding system, simultaneously clamps two containers on the inner and outer rings at the same radial position of the turntable, achieving double-layer clamping. This allows the number of containers processed per unit time to increase several times compared to the traditional single-layer structure. Combined with parallel feeding through the double bag feeding channels, it effectively avoids container queuing and ensures that the conveying cycle matches the high-speed rotation of the turntable, thereby significantly improving the overall filling speed and single-machine capacity.

[0040] 2. After each transportation cycle, the filling mechanism, cleaning mechanism, capping mechanism and bag ejection mechanism simultaneously operate on multiple sets of containers at their respective workstations, realizing parallel operation throughout the entire process and greatly improving equipment capacity.

[0041] 3. By using a dividing device located above the slot, the same slot is cleverly divided into two independent locking areas, inner and outer, achieving precise positioning and non-interfering guidance of the double-row containers. The protective part added to the outside of the dividing device effectively prevents the outer ring container from being accidentally thrown out during high-speed rotation.

[0047] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] The present application will be further described below with reference to the accompanying drawings.

[0049] This embodiment discloses a high-speed filling machine, which uses the aforementioned dual-row high-speed filling method, including a first bag storage mechanism 11, a second bag storage mechanism 12, a first bag feeding mechanism 21, a second bag feeding mechanism 22, a turntable mechanism, a filling mechanism 4, a cleaning mechanism 5, a capping mechanism, and a bag ejection mechanism 8.

[0050] The turntable mechanism includes a fixed plate, a turntable 3, a driving device, and a separating device 91. The driving device is used to drive the turntable 3 to rotate around its own axis. In this embodiment, the driving device includes a motor, a reducer, and a stepper. The outer periphery of the turntable 3 is uniformly provided with a plurality of elongated slots 31 for holding the container mouth of the stand-up pouch. The separating device 91 is located above the middle of the slot 31. Its orthographic projection divides the slot 31 below it into an inner ring clamping part 32 and an outer ring clamping part 33. The slots 31 at the same radial position of the turntable 3 can hold two containers at the same time, so that the number of containers processed per unit time can be increased several times compared with the traditional single-layer structure.

[0051] On the same side of turntable 3, the first bag feeding mechanism 21 and the second bag feeding mechanism 22 are arranged in parallel and opposite directions, while the first bag storage mechanism 11 and the second bag storage mechanism 12 are arranged opposite each other and respectively connected to the feeding end of the first bag feeding mechanism 21 and the second bag feeding mechanism 22. Arranging the two sets of bag feeding mechanisms in parallel and opposite directions on the same side of the turntable allows them to share the same space area, avoiding the waste of space caused by the two sets of mechanisms being scattered on both sides or at the front and rear ends of the turntable. The bag storage mechanism is arranged opposite each other at the feeding end, so that the feeding area is concentrated on the side or end of the equipment, and more space can be left on the other side of the turntable for operation or docking with other equipment.

[0052] The first bag feeding mechanism 21 and the second bag feeding mechanism 22 are used to transport the containers in the first bag storage mechanism 11 and the second bag storage mechanism 12 to the turntable. In this embodiment, the containers are stand-up pouches.

[0053] The outlet end of the first bag feeding mechanism 21 is located in front of the separating device 91 (the front specifically refers to the position that the turntable passes through first when rotating), and is used to feed the container into the inner ring clamping part 32; the outlet end of the second bag feeding mechanism 22 is located in front of the separating device 91, and the stand-up pouch conveyed by the second bag feeding mechanism 22 is blocked by the separating device 91 and stops in the outer ring clamping part 33 to achieve double-layer clamping;

[0054] The starting end of the separating device 91 is adjacent to the rear of the first bag feeding mechanism 21, and its end extends to the front of the bag unloading mechanism 8. The separating device 91 separates the slot behind the first bag feeding mechanism 21 to form an inner ring locking part 32 and an outer ring locking part 33 to achieve double-layer clamping and transportation. After filling, cleaning the container mouth and screwing on the cap, the inner ring locking part 32 and the outer ring locking part 33 are restored to the slot 31 in front of the bag unloading mechanism 8 so as to smoothly realize bag unloading.

[0055] The filling mechanism, cleaning mechanism, capping mechanism, and bag ejection mechanism are arranged sequentially around the turntable along its rotation direction. The filling mechanism and cleaning mechanism are located on the upper half of the fixed plate, while the capping mechanism and bag ejection mechanism are located on the lower half of the fixed plate. Dividing the functional area into upper and lower parts makes full use of the circumferential space of the fixed plate and avoids installation interference caused by all mechanisms being concentrated on one side. The filling and cleaning in the upper half involves material filling and media cleaning, which are far away from the capping and bag ejection in the lower half, effectively preventing material splashing in the filling area from contaminating the finished product area that has been capped.

[0056] The filling mechanism 4 includes eight sets of filling nozzles, each set of filling nozzles consisting of a filling nozzle facing the inner ring snap-fit ​​part and a filling nozzle facing the outer ring snap-fit ​​part;

[0057] The cleaning mechanism 5 includes eight sets of cleaning heads, each set consisting of a cleaning head facing the inner ring snap-fit ​​part and a cleaning head facing the outer ring snap-fit ​​part;

[0058] A cap feeding machine 6 is provided between the cleaning mechanism 5 and the capping mechanism 7. The capping mechanism 7 includes eight sets of capping heads. Each set of capping heads consists of a capping head facing the inner ring locking part and a capping head facing the outer ring locking part.

[0059] The bag ejection mechanism includes eight bag ejection cylinders, the number of which is equal to the number of filling nozzles.

[0060] When the filling mechanism is in operation, the cleaning mechanism, the capping mechanism, and the bag ejection mechanism operate simultaneously.

[0061] After each transportation cycle, the filling mechanism, cleaning mechanism, capping mechanism, and bag removal mechanism simultaneously perform filling, cleaning, capping, and bag removal on multiple sets of containers at their respective workstations, achieving parallel operation throughout the entire process and significantly improving equipment capacity.

[0062] The cleaning mechanism 5, the cap sorting machine 6, the cap screwing mechanism 7, and the bag unloading mechanism 8 mentioned above are existing technologies. Those skilled in the art can select them as needed, and they will not be described in detail here.

[0064] Preferably, a protective part 92 is also provided above the turntable 3. The protective part 92 is located outside the separating device 91 and is used to prevent the container contained in the outer ring locking part 33 from accidentally falling out when the turntable 3 rotates.

[0065] Preferably, the protective part 92 is located behind the outlet end of the second bag feeding mechanism 22, and the end of the protective part 92 corresponds to the end of the separating device 91 to facilitate bag unloading.

[0066] Preferably, the first storage bag mechanism 11 and the second storage bag mechanism 12 respectively include a batch carrying component 14 and a driving component; the batch carrying component 14 is used to simultaneously carry multiple containers in a parallel state, and a chute is provided below the batch carrying component 14, so that workers can place the container mouths of stand-up pouches into the chute to form a container row, and the container mouths can slide on the chute; the driving component is connected to the batch carrying component 14 and is used to drive the batch carrying component 14 to move stepwise along a preset path, and the driving component includes a drive motor and a chain 13, and the chain 13 is provided with clamps on both sides to transport the container row towards the first bag feeding mechanism 21 or the second bag feeding mechanism 22.

[0067] Preferably, the first bag feeding mechanism 21 and the second bag feeding mechanism 22 respectively include a clamping and transferring component and a separating and pushing component; the clamping and transferring component is used to move the batch carrying component 14 on the first bag storage mechanism 11 or the second bag storage mechanism 12 to the first bag feeding mechanism 21 or the second bag feeding mechanism 22, the clamping and transferring component includes a pneumatic finger 23 and a translation cylinder 25, the translation cylinder 25 drives the pneumatic finger 23 to move to both sides of the batch carrying component to clamp the batch carrying component 14, which drives the batch carrying component 14 and the container to be placed into the first bag feeding mechanism 21 or the second bag feeding mechanism 22; the separating and pushing component is used to separate the container from the batch carrying component to the slide rail 24 of the first bag feeding mechanism 21 or the second bag feeding mechanism 22, and transport it in the direction of the turntable 3, the separating and pushing device can be a bag feeding cylinder or a jet nozzle.

[0068] Preferably, the filling mechanism 4 further includes a material bucket 41 for feeding materials.

[0069] This embodiment discloses a dual-row high-speed filling method, including the following steps:

[0070] S1: The first bag storage mechanism 11 and the second bag storage mechanism 12, which are arranged opposite to each other, store containers respectively and transport the containers to the feeding ends of the first bag feeding mechanism 21 and the second bag feeding mechanism 22 arranged in parallel, to complete the pre-supply of double-row containers and prepare for subsequent double-row synchronous loading.

[0071] S2: The turntable 3 is evenly provided with several long strip-shaped slots 31 along its circumference, and the included angle between the center lines of two adjacent slots is 7.5°; the included angle between the lines connecting the center of the first bag feeding mechanism outlet end and the center of the second bag feeding mechanism outlet end to the center of the turntable is 15°, to ensure that the bag feeding station is accurately aligned with the slot 31.

[0072] Turntable 3 uses an intermittent rotation method, rotating 7.5° each time and then pausing. During each pause cycle:

[0073] The first bag feeding mechanism 21 pushes a first container into an empty slot. After being guided by the separating device, the first container enters the inner ring locking part 32 of the slot, thus completing the loading of the first container in the slot 31.

[0074] The slot 31, which has been loaded with the first container, continues to rotate with the turntable. When the slot 31 moves to the corresponding station of the second bag feeding mechanism 22, during the subsequent pause cycle, the second bag feeding mechanism 22 pushes a second container into the outside of the same slot. The second container is positioned and clamped by the outer protective part 92 of the slot 31, forming a set of double-layer clamped containers to be filled.

[0075] The above loading action is repeated cyclically. One transportation cycle is completed when eight consecutive sets of slots on the turntable complete double-layer clamping.

[0076] S3: The turntable rotates 60° every interval, which means that the eight sets of containers that have been loaded are transferred to the filling station as a whole; after the turntable stops, the filling mechanism 4 fills the sixteen containers located at the filling station with materials simultaneously through the sixteen filling nozzles.

[0077] S4: After one transportation cycle, the turntable rotates 60° intermittently to transfer the eight sets of containers that have been filled to the cleaning station as a whole; after the turntable stops, the cleaning mechanism 5 uses sixteen cleaning heads to simultaneously clean the nozzles of the eight sets of containers to remove residual materials from the nozzles.

[0078] S5: In one transport cycle, the turntable rotates intermittently by 60°, sequentially transferring the eight groups of cleaned containers through the corresponding workstations of the cap sorting machine 6; the turntable pauses once every 7.5 degrees of rotation, and the cap sorting machine 6 simultaneously supplies caps to the container mouths of a group of containers;

[0079] S6: After one transport cycle, the turntable rotates 60° intermittently, transferring eight sets of containers equipped with caps to the capping mechanism. The capping mechanism uses sixteen capping heads to simultaneously cap and seal the eight sets of containers located at the capping station.

[0080] S7: After one transportation cycle, the turntable rotates intermittently by 60° to transfer the eight sets of containers that have been capped to the unloading station; the unloading mechanism simultaneously ejects the first and second containers from the eight sets of containers from the inside and outside of the slots, respectively, to complete the collection of finished containers;

[0081] The above steps are repeated. During the pause when the turntable rotates 60°, each station simultaneously performs the corresponding operation on the container group currently located at its station, realizing continuous and efficient filling under parallel operation throughout the entire process.

During the pause after the turntable rotates by an angle Mα, each station simultaneously performs filling, cleaning, capping, and bag removal on the container group currently located at its station, achieving continuous and efficient filling under parallel operation throughout the entire process.
