Description

Technical Field

[0001] This utility model relates to the field of automation technology, specifically to a cap removal device and a filling system. Background Technology

[0002] When producing different products, filling systems require changing the cap type. Currently, changing the cap type in a filling system requires replacing the cap feeder cap type parts and cap slides, which is inconvenient and time-consuming. Furthermore, some application scenarios require the simultaneous use of both inner and outer caps. Utility Model Content

[0003] To address the above problems, this utility model provides a cap removal device that allows for more convenient cap replacement and meets the need to use both inner and outer caps simultaneously, reducing operational complexity and improving production efficiency.

[0004] The first aspect of this utility model provides a cap-removing device comprising a rotating track, a cap-hanging mechanism, multiple lower cap tracks, and multiple disengagement devices. The rotating track is configured to rotate on a horizontal plane. The inner radial end of the cap-hanging mechanism is connected to the rotating track, and the outer radial end of the cap-hanging mechanism has a cap-hanging head that protrudes upward along the height direction. The end of each lower cap track has a cap-hanging opening that holds the cap with the cap opening exposed downward. The cap-hanging head can rotate along the rotating track to a corresponding position below the cap-hanging opening. The multiple disengagement devices are configured to respectively drive the movement of the cap-hanging openings of the multiple lower cap tracks, thereby causing the cap-hanging openings to approach or move away from the rotation plane of the cap-hanging mechanism.

[0005] A rotating track allows for easy reciprocating movement of the cap-hanging mechanism between the cap-hanging and cap-retrieving positions. Multiple lower cap tracks can accommodate caps of different types. When a specific cap type is needed, a disengagement device detaches the lower cap tracks of other cap types from the rotating plane, while keeping the lower cap track of the desired cap type close to the rotating plane. This simple disengagement mechanism allows for easy and quick cap type switching, significantly improving efficiency.

[0006] Optionally, the angle between the cap inside the cap hanging opening and the horizontal plane is 1°-90°. By tilting the cap inside the cap hanging opening relative to the horizontal plane, the cap can be removed from the hanging opening as long as it abuts against the inner wall of the cap during horizontal movement, and the cap continues to move towards the removal position. This cap removal method is simple and quick, and the use of the disengagement device allows for more stable control of the cap hanging opening position, precisely completing the cap hanging action.

[0007] Optionally, the disengagement device is a pneumatic cylinder or an electric cylinder, the free end of which is connected to the lower cover track and can move along the height direction. By driving the lower cover track to move linearly in the direction of gravity through the pneumatic cylinder or electric cylinder, the position of the cover opening can be accurately positioned, ensuring the stable operation of the cover hanging action.

[0008] Optionally, the rotary track includes two parallel rotating wheels and a chain or timing belt mounted between the two wheels. The straight side of the capsule-shaped rotary track can be easily set up with multiple cap-removing or cap-filling stations, facilitating the simultaneous capping of multiple cans.

[0009] Optionally, multiple lower cover tracks are arranged on the same side of the rotating track and sequentially along a direction parallel to the chain or timing belt. This configuration of the lower cover tracks results in a more compact structure, and the multiple lower cover tracks can work together in coordination.

[0010] Optionally, it includes multiple cover-hanging mechanisms, arranged at equal intervals along the circumferential direction of the rotating track.

[0011] Optionally, the device also includes a capping mechanism, which has multiple capping heads located on the opposite side of the rotating track from the lower cap track, and arranged sequentially along a direction parallel to the chain or timing belt. The center distance between the capping heads of the multiple capping mechanisms is equal to the center distance between the cap hanging heads. Using multiple cap hanging mechanisms and multiple capping mechanisms allows for the simultaneous filling of multiple containers, improving production efficiency. The equal center distance arrangement results in a more compact structure and less interference between them.

[0012] The second aspect of this utility model provides a filling system, including the cap removal device provided in the first aspect of this utility model. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] When producing different products, the filling system may need to be flexibly adjusted according to the requirements of different products. For example, in some implementations, different products require different filling methods; for instance, low-viscosity products use gravimetric filling, while high-viscosity products use plunger filling. In other implementations, different products use different bottle shapes, and changing the bottle shape requires replacing parts such as the bottle guard plate, which is inconvenient and time-consuming. Similarly, in some implementations, different products use different cap shapes, and changing the cap shape requires replacing cap feeder cap parts and cap slides, which is also inconvenient and time-consuming.

[0026] Therefore, in order to solve the above problems, some embodiments of this utility model provide a filling system 100, which can easily adjust the target filling method, bottle type or cap type, and quickly and efficiently adapt to the production of different products.

[0027] <Bottling System 100>

[0028] Figure 1 This is a schematic diagram of the structure of a filling system 100 provided in an embodiment of this utility model. (Reference) Figure 1 In some embodiments of this utility model, the filling system 100 includes a control unit 200, a container transport unit 300, a filling unit 400, and a capping unit 500. The container transport unit 300, the filling unit 400, and the capping unit 500 are all communicatively connected to the control unit 200, and the control unit 200 uniformly controls the coordinated operation of each component.

[0029] The container transport unit 300 further includes a container inlet mechanism 310, a first pick-and-place device 320, a pusher device 330, a second pick-and-place device 340, and a container outlet mechanism 350. The container conveying mechanism 310 is used to transport containers 600 (such as bottles, cans, barrels, etc.) from upstream processing equipment to filling system 100; the first pick-and-place device 320 is used to remove a specified number of containers 600 from the container conveying mechanism 310, hold the containers 600 and place them at a specified position on the pushing device 330; the pushing device 330 pushes the containers 600 sequentially through each part of the filling system 100 while maintaining the relative positional relationship of each container 600, to complete the filling and capping operations; the second pick-and-place device 340 is used to remove the containers 600 that have completed the filling and capping operations from the pushing device 330, hold the containers 600 and place them on the container output mechanism 350; the container output mechanism 350 is used to further transport the processed containers 600 to downstream processing equipment.

[0030] The filling unit 400 is used to fill the container 600. Filling methods include, but are not limited to, weighing filling and plunger filling. Weighing filling is generally suitable for liquids or semi-fluids with good flowability or medium viscosity, such as edible oils, chemical liquids, detergents, liquid waste, honey, syrups, wine, and beverages. Plunger filling is generally suitable for medium-to-high viscosity substances, such as liquids, granules, or pastes that are not easily flowable or have poor flowability, such as sauces, cosmetics, ointments, gels, creams, and fruit drinks. In some embodiments of this invention, the filling unit 400 of the filling system 100 can be flexibly selected to efficiently adapt to the filling of different substances.

[0031] The cap loading unit 500 further includes a cap lifting and loading machine 510, a cap sorting machine 520, a cap taking device 530, and a cap loading device 540 for sorting, taking, and assembling caps 700. The cap lifting and loading machine 510 can lift the caps 700. The lifted caps 700 are further conveyed to the cap sorting machine 520, which can arrange the placement orientation of the caps 700. In some other embodiments, the cap lifting and loading machine 510 can also classify irregularly placed caps 700 based on their center of gravity position. Caps 700 that conform to the placement orientation requirements will be lifted, while caps 700 that do not conform to the placement orientation requirements cannot be lifted or will fall halfway, thereby selecting or arranging the placement orientation of the caps 700.

[0032] The cap-removing device 530 includes a rotating track 531, a cap-hanging mechanism 532, a lower cap track 533, and a release device 534. The outlet of the cap 700 from the cap sorting machine 520 is connected to the lower cap track 533. The cap 700 falls along the lower cap track 533 to a position substantially flush with the rotating track 531 and the cap-hanging mechanism 532. The cap-hanging mechanism 532 is driven by the rotating track 531 to rotate on a horizontal plane, reciprocatingly hooking the cap 700 at the bottom of the lower cap track 533 and conveying it to the cap-loading device 540. The cap-loading device 540 can be, for example, a cap-pressing device or a cap-screwing device, assembling the cap 700 onto the top of the container 600 by pressing or screwing it on, preventing leakage of the contents of the container 600, and completing the sealing. In some embodiments of this utility model, to meet the need for quick cap replacement, the cap-removing device 530 includes multiple lower cap tracks 533, each of which can be adapted to the supply of a single type of cap 700. There are also multiple release devices 534, which are respectively set to correspond to each lower cover track 533. They can make the lower cover track 533 enter or disengage from its predetermined station, thereby automatically selecting the appropriate cover type according to production needs using the release device 534.

[0033] The container 600, which has been capped by the capping device 540, will be removed from the conveying device 330 by the second pick-and-place device 340 and placed on the container conveying mechanism 350. The container conveying mechanism 350 will then transport the processed container 600 to downstream processing equipment for further processing, such as cleaning, quality inspection, or boxing.

[0034] The above is a brief introduction to the system structure and operation mode of the filling system 100 in some embodiments of this utility model. The following describes each component of the filling system 100 and its functional characteristics.

[0035] <Container Transportation Department 300>

[0036] Figure 2 This is a schematic diagram (top view) of the container transport unit 300 in some embodiments of this utility model. In this embodiment, containers 600 are filled and capped in groups of six. Each group of containers 600 advances at a predetermined step length cycle, thereby achieving more stable and regular filling and capping, and simultaneously filling and capping multiple containers 600 simultaneously also improves production efficiency. Based on the above objectives, the following... Figure 2 The container transport section 300 is shown.

[0037] refer to Figure 2 The container conveying mechanism 310 can continuously convey containers 600 from the upstream processing equipment and temporarily place them on the platform above the starting position of the conveying equipment 330. The first pick-and-place device 320 uses a clamp to remove a group of six containers 600 from the platform and place them on the conveying equipment 330 at a time.

[0038] Figure 3 This is a schematic diagram (front view) of the pushing device 330 in some embodiments of this utility model. (Reference) Figure 2 and Figure 3 The conveying device 330 includes a pair of rollers 331 and a conveyor belt 332 sleeved on the outer periphery of the rollers 331 and bridging the two rollers 331. A push plate 333 is provided on the surface of the conveyor belt 332.

[0039] Some filling systems 100 assist in the conveying of the container 600 by using clamps to hold the constricted portion of the container 600, thus preventing the container 600 from tipping over. However, this method requires frequent changes to the clamps and gripping methods depending on the type and size of the container 600, resulting in poor versatility. Without clamps, it is difficult to move the container 600 quickly, making it prone to tipping over. In some embodiments of this invention, a pusher plate 333 is provided protruding from the surface of the conveyor belt 332. The front side wall of the pusher plate 333 in the direction of movement can abut against the container 600, preventing tipping due to excessive acceleration and insufficient static friction.

[0040] Figure 4 This is a top view (structural schematic diagram) of the push plate 333 in some embodiments of this utility model. (Reference) Figure 4 The push plate 333 has a V-groove 334 on the side that abuts against the container 600, corresponding to the number of a group of containers 600 (6 in this embodiment). Each push plate 333 also has six V-grooves 334, and the six V-grooves 334 are evenly spaced.

[0041] For containers 600 with different cross-sectional sizes, for example Figure 4 The containers 600 shown have circular cross-sections with varying radii. The V-grooves 334 can limit their positions, roughly confining them to the direction of their central axis, thus preventing collisions between the containers 600. In this way, even if the size or dimensions of the containers 600 change, they can still be reliably limited and propelled without replacing the pusher plate 333, reducing the possibility of the containers 600 tipping over.

[0042] <Bottling Section 400>

[0043] Different products require different filling materials. As mentioned earlier, gravimetric filling is generally used for liquids or semi-fluids with good flowability or medium viscosity, while plunger filling is generally used for medium to high viscosity substances, such as liquids, granules, or pastes that are not easy to flow or have poor flowability.

[0044] To improve the adaptability and versatility of the filling system 100 for different material filling needs, some embodiments of this utility model have modularized the components used in filling methods such as weighing filling and plunger filling. Specifically, the filling system 100 provides independent weighing filling modules 410 and plunger filling modules 420. Technicians can select and install the corresponding weighing filling modules 410 and plunger filling modules 420 on the filling unit frame 460 of the filling unit 400 as needed. Specifically, "modularization" means that each station of the filling unit frame 460 can install both the weighing filling module 410 and the plunger filling module 420. For example, each station of the filling unit frame 460 provides both mounting brackets for the weighing filling module 410 and the plunger filling module 420, or the provided brackets are suitable for the installation of both the weighing filling module 410 and the plunger filling module 420. On the other hand, the size and shape of the weighing filling module 410 and the plunger filling module 420 are suitable for installation into the filling unit frame 460.

[0045] In some embodiments of this utility model, a filling unit frame 460 provides two workstations. The filling unit frame 460 can be equipped with a single weighing filling module 410, or a single plunger filling module 420, or a combination of weighing filling module 410 and plunger filling module 420.

[0046] Figures 5-8 This is a schematic diagram showing different combinations of filling modules optionally mounted on the filling unit frame 460 in some embodiments of this utility model. (Reference) Figure 5 The filling unit frame 460 is equipped with a weighing and filling module 410 at the second station 450. (Reference) Figure 6 The filling unit frame 460 has a plunger filling module 420 installed at the first station 440. (Reference) Figure 7 The filling unit frame 460 has a plunger filling module 420 installed at the first station 440 and a weighing filling module 410 installed at the second station 450. (Reference) Figure 8 The filling unit frame 460 is equipped with weighing and filling modules 410 at both workstations.

[0047] It should be noted that the above are only some examples of combinations in some embodiments of this utility model, and this utility model is not limited thereto. In other embodiments of this utility model, a filling unit frame 460 may provide three or more workstations, and the corresponding modular filling modules are not limited to the weighing filling module 410 and the plunger filling module 420.

[0048] Additionally, refer to Figures 5-8 In some embodiments of this invention, the weighing and filling module 410 requires the use of a weighing sensor 430, while the plunger filling module 420 does not. Correspondingly, in some embodiments of this invention, weighing sensors 430 can be installed at positions on the conveying device 330 corresponding to the filling stations. When a plunger filling module 420 is installed above the station corresponding to the weighing sensor 430, the weighing sensor 430 can be disabled via the control unit 200; conversely, when a weighing and filling module 410 is installed above the station corresponding to the weighing sensor 430, the weighing sensor 430 is re-enabled. This approach allows for flexible handling of different filling requirements, reduces the complex work caused by changes to the device itself, and improves production efficiency.

[0049] <Cap removal device 530 and cap application device 540>

[0050] Figure 9 This is a schematic diagram of the structure of the cap removal device 530 and the cap installation device 540 provided in some embodiments of this utility model. Figure 10 yes Figure 9A schematic diagram illustrating the cooperation method and process between the cap-removing device 530 and the cap-installing device 540 in the embodiment.

[0051] refer to Figure 9 The cap removal device 530 includes a rotating track 531, a cap hanging mechanism 532, and a cap lowering track 533. The cap loading head 542 of the cap loading mechanism 541 of the cap loading device 540 and the cap hanging opening 535 of the cap lowering track 533 of the cap removal device 530 are respectively located on both sides of the rotating track 531. The rotating track 531 can drive the rotation of the cap hanging mechanism 532, thereby transferring the cap 700 between the cap hanging opening 535 of the cap lowering track 533 and the cap loading head 542 of the cap loading mechanism 541.

[0052] refer to Figure 10 , Figure 10 The leftmost figure shows a situation where a cap 700 is hung on the cap hanging head 536 of the cap hanging mechanism 532 and moves to below the cap loading head 542 of the cap loading mechanism 541. Then, the cap loading head 542 of the cap loading mechanism 541 moves down and grabs the cap 700 on the cap hanging head 536. Figure 10 The second picture on the left and Figure 10 The middle diagram illustrates the process of the cap-attaching head 542 moving down to grab the cap 700. Then, the rotating track 531 drives the cap-hanging head 536 of the cap-hanging mechanism 532 to rotate below the lower cap track 533 to receive the cap 700 as it falls back into the cap-hanging opening 535. Simultaneously, the cap-attaching head 542, having grabbed the cap 700, works to complete the cap-attaching operation. Figure 10 China Library Figure 10 The second picture on the right and Figure 10 The right-hand figure illustrates the synchronous operation of the aforementioned cap-mounting head 542 and cap-hanging head 536. (The last sentence appears to be incomplete and possibly refers to a different topic.) Figure 10 After the capping and hanging operations are completed, as shown in the right figure, the capping head 542 moves upward, and the rotating track 531 drives the hanging head 536 of the hanging mechanism 532 to move back to the starting position. Figure 10 The state shown in the left image indicates the start of the next cycle. This is achieved through repeated execution. Figure 10 As shown in the process, the rotating track 531 and the cap hanging mechanism 532 reciprocate between the lower cap track 533 and the cap loading mechanism 541 to transfer the cap 700, automatically completing the cap removal and cap loading process.

[0053] In some embodiments of this invention, the rotating track 531 has multiple (six in this embodiment, corresponding to a group of six containers 600) capping mechanisms 532, and multiple caps 700 can be picked up in each cycle of rotation. Correspondingly, the capping device 540 has multiple (also six in this embodiment) capping mechanisms 541, and each capping mechanism 541 can complete the capping operation of one container 600 in each cycle. That is, the filling system 100 provided in this embodiment can simultaneously complete the pushing, filling and capping operations of multiple containers 600, improving production efficiency.

[0054] For information on how the cap-retrieving device 530 retrieves six caps 700 in one cycle, please refer to [reference needed]. Figure 11 and Figure 12 The content shown. Figure 11 yes Figure 9 A schematic diagram of the cap-removing device 530 is shown along direction A. Figure 12 It is along Figure 9 A schematic diagram of the rotating track 531 viewed from a top-down perspective.

[0055] refer to Figure 11 The cap removal device 530 includes multiple lower cap tracks 533, which are arranged on the same side of the rotating track 531. The end of the lower cap track 533 is provided with a cap hanging opening 535. The cap hanging opening 535 clamps the cap 700 so that the cap opening of the cap 700 is exposed downward. The cap hanging head 536 can rotate along the rotating track 531 to the corresponding position below the cap hanging opening 535.

[0056] Since the cover head 536 protrudes upwards along the height direction, the top height of the cover head 536 roughly corresponds to the position of the cover opening 535. Specifically, refer to... Figure 11 The cover 700 is held in a direction inclined to the horizontal plane. Preferably, the angle θ between the cover 700 and the horizontal plane within the cover opening 535 is 1° to 90°. The right side of the bottom annular outer edge of the cover 700 is lower than the left side. When the cover head 536 moves from left to right, since the top height of the cover head 536 is higher than the right side of the bottom annular outer edge of the cover 700 and lower than the left side, the cover head 536 will first abut against the inner wall of the right side of the bottom annular outer edge of the cover 700, and use the pressure to remove the cover 700 from the cover opening 535. After the cover 700 is removed from the cover opening 535, it will remain horizontally held by the cover head 536 and continue to be conveyed by the rotating track 531.

[0057] In some embodiments of this utility model, each lower cover track 533 can be configured with a cover 700 of different size or type. When a certain type of cover 700 is needed, the lower cover track 533 of the cover 700 not in use can be decoupled from the cover hanging mechanism 532 using the disengagement device 534, while the lower cover track 533 of the cover 700 of the type to be used can be coupled to the cover hanging mechanism 532. Specifically, the disengagement device 534 is a cylinder or an electric cylinder, the free end of which is connected to the lower cover track 533, and can drive the lower cover track 533, especially the cover hanging opening 535 of the lower cover track 533, to move along the height direction.

[0058] When the cover opening 535 moves downwards along the height direction to the point closest to the rotation plane of the cover mechanism 532, the lower cover track 533 couples with the cover mechanism 532. At this height position, i.e., the height of the top of the cover head 536 as described above (higher than the right side of the bottom annular outer edge of the cover 700 and lower than the left side of the bottom annular outer edge of the cover 700), the cover head 536 can efficiently remove the cover 700 from the cover opening 535. When the cover opening 535 moves upwards along the height direction to a height far from the rotation plane of the cover mechanism 532, the lower cover track 533 decouples from the cover mechanism 532. At this height position, the corresponding lower cover track 533 is not used. In this way, one of multiple lower cover tracks 533 can be selected for use, that is, the lower cover track 533 corresponding to the appropriate cover type can be put into use. Moreover, the above process can be completed simply by controlling the disengagement device 534, making the operation simpler and more convenient to complete the selection and replacement of the cover type.

[0059] Figure 12 It is along Figure 9 A schematic diagram of the rotating track 531 viewed from a top-down perspective. (Reference) Figure 12 The rotating track 531, configured to rotate on a horizontal plane, includes two wheels 537, one on the right and one on the left. The right wheel 537 is the driving wheel, and the left wheel 537 is the driven wheel. A chain 538 is strung between the driving and driven wheels, and a connector 539 is mounted on the outer surface of the chain 538. The cover-hanging mechanism 532 is detachable from the connector 539. Specifically, in this embodiment, the rotating track 531, in conjunction with the cover-hanging mechanism 532, needs to retrieve six covers 700 in one cycle. Accordingly, the six cover-hanging mechanisms 532 can be sequentially mounted on six connecting connectors 539. In this way, in one rotation cycle of the rotating track 531, the six cover-hanging heads 536 of the six cover-hanging mechanisms 532 can sequentially retrieve six covers 700 as they pass through the cover-hanging opening 535, and rotate with the covers 700 to the position below the cover-mounting head 542.

[0060] The multiple capping mechanisms 541 of the capping device 540 are equally spaced. Specifically, multiple capping heads 542 are equally spaced along a direction parallel to the chain 538 or the timing belt. Correspondingly, the cap hanging mechanisms 532 are also equally spaced, with the center distance d1 between the capping heads 542 equal to the center distance d2 between the cap hanging heads 536, thus ensuring the accuracy of the docking between the cap hanging heads 536 and the capping heads 542. The capping mechanisms 541 and the lower cap track 533 are respectively arranged on both sides of the rotating track 531 to facilitate the arrangement of the capping device 540 and the cap taking device 530 along the production line.

[0061] In some embodiments of this utility model, the two pulleys 537 can also be connected by other conveying devices such as a timing belt. The "extension direction of the chain 538 (or timing belt)" referred to herein corresponds to the direction of the line connecting the central axes of the two pulleys 537.

[0062] In some other embodiments of this invention, the projection of the extension direction of the lower cover track 533 onto the horizontal plane is parallel to the extension direction of the chain 538 or the timing belt. In this way, the lowest point of the bottom annular outer edge of the cover 700 can abut against the cover hanger 536 at a more suitable angle, facilitating the removal of the cover 700 by the cover hanger 536. In other embodiments of this invention, the projection of the extension direction of the lower cover track 533 onto the horizontal plane may also be inclined to the extension direction of the chain 538 or the timing belt; this invention does not limit this.

[0063] Through the above methods, the filling system 100 provided by the embodiments of this utility model can be applied to filling different cap types, different bottle types and different substances, greatly improving the flexibility of use, and effectively shortening the time for changing to adapt to different cap types, bottle types and substances for filling, thereby improving production efficiency.

[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
