Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically, to an automatic bagging and packaging machine for round bottles. Background Technology

[0002] With the continuous development of my country's science and technology and economy, the cost of manual labor has been increasing, leading to the emergence of automated equipment for various production stations, which has promoted the improvement of product quality and production efficiency.

[0003] For example, product bagging, a task that previously required manual labor, is gradually being replaced by automated bagging equipment. However, due to the varying shapes, sizes, and weights of products to be packaged, current automated bagging equipment cannot be directly applied to the automatic bagging of all products. For instance, there is still a lack of highly effective automated packaging equipment for bagging round bottles such as glass and plastic bottles.

[0004] For example, patent document CN202223100585.3, entitled "An Automatic Bag Filling and Sealing Device," discloses an automatic bag filling and sealing device, including a bag storage mechanism and a bag filling mechanism, as well as a frame, a bag picking mechanism, a conveying mechanism, a bag opening mechanism, and a sealing mechanism. The conveying mechanism is mounted on the frame, the bag storage mechanism is mounted at one end of the frame, the bag picking mechanism is mounted above the bag storage mechanism, the bag opening mechanism and the sealing mechanism are both mounted above the conveying mechanism, the sealing mechanism is located at the end of the frame away from the bag storage mechanism, and the bag filling mechanism is located to the side of the bag opening mechanism. This device has the advantages of bagging one bag at a time and using a suction conveyor belt to ensure that the bags do not shift. However, its conveying mechanism is designed for clothing products and cannot be used for bagging round bottles.

[0005] Patent document CN202110334589.9, entitled "A Vacuum Packaging Machine for Ink Bottle Packaging," discloses a vacuum packaging machine for ink bottle packaging. The machine includes a feeder, a feeding component on one side of which orients and transports ink bottles, and a sorting component on the side away from the feeder which sorts ink bottles in the same direction. A lifting component is located on one side of the sorting component, and the lifting component and sorting component are structurally compatible. A bag-feeding component is located on one side of the lifting component, facing downwards, which moves the packaging bag. Through the structural cooperation between the bag-feeding component and the bag-covering component, the problem of easily torn packaging bags in existing technologies can be effectively solved. Combined with a pushing component, the ink bottle and packaging bag are pushed into the transport trough. Then, a bag-supporting head releases the packaging bag, and the transport trough continues to transport the packaged ink bottle to the next process, facilitating subsequent vacuum sealing of the packaging bag. Although the aforementioned equipment has undergone structural optimization for automatic bottle bagging, when the packaging bag is opened by the bag-holding head and pushed into the bottle, the contact point between the packaging bag and the bag-holding head is prone to tearing due to stress, as the packaging bag is supported solely by the bag-holding head. Furthermore, during the pushing of the bottle into the packaging bag and the pushing of both the bottle and packaging bag into the transport chute, the significant displacement of both can easily lead to misalignment and mutual pulling, causing the packaging bag to tear.

[0006] In conclusion, if the characteristics of the two types of equipment mentioned above can be combined, and the positioning stability of packaging bags and bottles during bagging can be improved in a targeted manner, the current technical problem of lacking stable round bottle bagging packaging equipment will be effectively solved, the quality of automated bagging of round bottles will be effectively improved, and adverse phenomena such as packaging bag tearing will be avoided. Summary of the Invention

[0007] To address the issue that existing automatic bottle bagging and packaging equipment on the market suffers from significant relative displacement between the packaging bag and the bottle during operation, posing a risk of bag tearing and leaving considerable room for improvement in operational stability, an automatic bagging and packaging machine for round bottles is provided.

[0008] An automatic bagging and packaging machine for round bottles includes a bag storage mechanism, a bag retrieval mechanism, a suction conveyor belt, and a bag opening mechanism arranged sequentially. A bag filling mechanism is located on the opposite side of the suction conveyor belt from the bag opening mechanism. The bag opening mechanism includes a suction cup assembly and a circular support assembly. The suction cup assembly is located on the side of the suction conveyor belt and includes symmetrically arranged automatic suction cups. Each automatic suction cup is connected to a telescopic push rod at its rear. The circular support assembly is located on the side of the suction cup assembly away from the suction conveyor belt and includes a first arc-shaped plate and a second arc-shaped plate that can be symmetrically opened and closed. Both the first and second arc-shaped plates are connected to front and rear drives. The bag filling mechanism includes a product conveyor belt and a translation push rod. The end of the product conveyor belt is located behind the circular support assembly. The midpoint between the translation push rod and the first and second arc-shaped plates is on the same straight line. The translation push rod is located above the end of the product conveyor belt on the opposite side from the circular support assembly.

[0009] Furthermore, the first arc-shaped plate and the second arc-shaped plate are respectively installed at the left and right ends of the synchronous opening and closing cylinder, the top of the synchronous opening and closing cylinder is connected to the guide rail platform, and the guide rail platform is connected to the front and rear drives.

[0010] Furthermore, a lifting support plate is provided below the midpoint between the first arc-shaped plate and the second arc-shaped plate, and the maximum height of the lifting support plate is equal to the height of the top plane of the suction conveyor belt.

[0011] Furthermore, the front ends of the first and second arc-shaped plates are provided with forward-extending arc-shaped support pouches, and the rear ends of the first and second arc-shaped plates are connected with arc-shaped outward-expanding guide plates.

[0012] Furthermore, a bracket platform with the same moving direction as the translation push rod is provided below the product conveyor belt and above the corresponding end of the product conveyor belt. A concave conveyor seat is installed on the bracket platform.

[0013] Furthermore, limit baffles are provided on the upper left and right sides of the product conveyor belt, and telescopic baffles are provided at the ends of the limit baffles. The translation push rod is located on the side of the corresponding telescopic baffle away from the limit baffle.

[0014] Furthermore, a sealing mechanism is provided downstream of the bag opening mechanism and above the suction conveyor belt. The sealing mechanism includes a hot cutting blade and a heat insulation pad arranged symmetrically at the top and bottom. Both the hot cutting blade and the heat insulation pad are connected to a lifting linkage. A telescopic suction pipe is provided between the hot cutting blade and the heat insulation pad.

[0015] Furthermore, a translation gripper is provided above the suction conveyor belt corresponding to the stroke between the bag opening mechanism and the bag sealing mechanism. The translation gripper includes a translation base, a lifting platform and a gripping gripper. The lifting platform is installed on the translation base, and the gripping gripper is installed at the bottom of the lifting platform. An inner concave sleeve is provided on the inner side of the gripping gripper.

[0016] Furthermore, the bag storage mechanism includes a circulating conveyor belt with multiple bag storage compartments, and the bag retrieval mechanism is located above the bag storage compartments on the top of the circulating conveyor belt, near the side of the suction conveyor belt.

[0017] Furthermore, the suction conveyor belt is provided with multiple ventilation holes, and multiple vertically downward suction fans are installed horizontally inside the suction conveyor belt.

[0018] The advantages of this invention are:

[0019] 1. In addition to the upper and lower suction cups, a circular support component is also provided when the bag is opened, which extends forward after the upper and lower suction cups open and provides a circular support channel. This can effectively prevent the round bottle from not being able to be inserted into the packaging bag due to the mismatch between the opening shape of the round bottle and the packaging bag.

[0020] 2. The round support assembly is equipped with arc-shaped bag support pieces, arc-shaped outward expansion guide plates, and lifting support plates to ensure that the round bottle can be accurately inserted into the packaging bag, significantly improving the positioning accuracy of the round bottle when being inserted into the packaging bag.

[0021] 3. Round bottles are pushed into the packaging bag by being laid horizontally and moved horizontally. This method is more stable than the vertical bagging path and is less susceptible to displacement of the packaging bag or round bottle due to gravity.

[0022] 4. A bracket platform is installed to horizontally position and push over the upright round bottles, which can be directly connected to the end of the production line for round bottle products.

[0023] 5. The opening mechanism and the sealing mechanism use a translational gripper to transport the round bottle, which can prevent the round bottle from rolling and shifting when it is placed horizontally on the suction conveyor belt, thus avoiding misalignment of the sealing mechanism.

[0024] 6. The packaging bags are picked up one by one and transported forward using a bag-picking mechanism in conjunction with a suction conveyor belt, which effectively avoids the phenomenon of multiple packaging bags sticking together and packaging bag positioning deviation during transportation.

[0025] 7. The bag storage mechanism is equipped with multiple bag storage compartments. Workers can continuously add packaging bags to the bag storage compartment behind the one that is currently retrieving bags. The equipment will not stop because of the need to add packaging bags, resulting in high work efficiency. Attached Figure Description

Detailed Implementation

[0035] To address the issue that existing automatic bottle bagging and packaging equipment on the market suffers from significant relative displacement between the packaging bag and the bottle during operation, posing a risk of bag tearing and leaving considerable room for improvement in operational stability, an automatic bagging and packaging machine for round bottles is provided.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0039] like Figures 1 to 6As shown, this embodiment provides an automatic bagging and packaging machine for round bottles, including a bag storage mechanism 1, a bag retrieval mechanism 2, a suction conveyor belt 3, and a bag opening mechanism 4 arranged sequentially. A bag filling mechanism 5 is located on the opposite side of the bag opening mechanism 4 from the suction conveyor belt 3. The bag opening mechanism 4 includes a suction cup assembly and a circular support assembly. The suction cup assembly is located on the side of the suction conveyor belt 3 and includes symmetrically arranged automatic suction cups 401. A telescopic push rod 402 is connected to the rear of each automatic suction cup 401. The circular support assembly is located on the suction cup assembly away from the suction conveyor belt 3. On one side, the circular support assembly includes a first arc plate 403 and a second arc plate 404 that can be symmetrically opened and closed. Both the first arc plate 403 and the second arc plate 404 are connected to front and rear drives 407. The bagging mechanism 5 includes a product conveyor belt 501 and a translation push rod 502. The end of the product conveyor belt 501 is located behind the circular support assembly. The midpoint between the translation push rod 502 and the first arc plate 403 and the second arc plate 404 is on the same straight line. The translation push rod 502 is located above the end of the product conveyor belt 501 on the opposite side of the circular support assembly.

[0040] The key feature of this automatic round bottle bagging equipment is that after the automatic suction cups 401 open the bag opening of the packaging bag 10, the front and rear drive 407 (generally a linear cylinder) pushes the first arc plate 403 and the second arc plate 404 into the opened bag opening. The outward opening of the first arc plate 403 and the second arc plate 404 supports the bag opening and creates a stable near-circular opening. Then, the translation push rod 502 can be used to push the round bottle 11 laterally into the packaging bag 10 through the channel formed by the opening of the first arc plate 403 and the second arc plate 404, which effectively ensures that the round bottle 11 can be accurately positioned and placed in the packaging bag 10.

[0041] It should be noted that the bag-picking mechanism 2 can directly use a conventional design in the art, namely multiple downward-facing automatic suction cups 401 connected to the lifting mechanism and the translation mechanism, which will not be described in detail here. The suction conveyor belt 3 can also use a conventional design in the art.

[0042] The first arc-shaped plate 403 and the second arc-shaped plate 404 are respectively installed at the left and right ends of the synchronous opening and closing cylinder 405. The top of the synchronous opening and closing cylinder 405 is connected to the guide rail platform 406, which is connected to the front and rear drive 407. The synchronous opening and closing cylinder 405 is a commonly used pneumatic gripper mechanism, which can ensure the stable opening and closing of the first arc-shaped plate 403 and the second arc-shaped plate 404. The guide rail platform 406 ensures that the first arc-shaped plate 403 and the second arc-shaped plate 404 can move back and forth stably and synchronously.

[0043] A lifting support plate 408 is provided below the midpoint between the first arc-shaped plate 403 and the second arc-shaped plate 404. The maximum height of the lifting support plate 408 is equal to the height of the top plane of the suction conveyor belt 3. Since the first arc-shaped plate 403 and the second arc-shaped plate 404 need to open and close, there must be a gap between them. To prevent the round bottle 11 from tilting downwards through the gap between the first arc-shaped plate 403 and the second arc-shaped plate 404, the lifting support plate 408 is provided to support the bottom of the round bottle 11 when it passes through the first arc-shaped plate 403 and the second arc-shaped plate 404.

[0044] The first arc-shaped plate 403 and the second arc-shaped plate 404 are provided with forward-extending arc-shaped bag-supporting pieces 8 at their front ends, and an arc-shaped outward-expanding guide plate 9 is connected to the rear of the first arc-shaped plate 403 and the second arc-shaped plate 404. The arc-shaped outward-expanding guide plate 9 can guide the round bottle 11, which is tilted laterally, into the channel between the first arc-shaped plate 403 and the second arc-shaped plate 404 when it is pushed forward by the translation push rod 502, so as to prevent the round bottle 11 from getting stuck during the pushing process. The arc-shaped bag-supporting pieces 8 can support the packaging bag 10 and provide guidance for the round bottle 11 when it enters the packaging bag 10, so that the round bottle 11 can be stably pushed into the packaging bag 10.

[0045] Below the translation push rod 502, above the end of the product conveyor belt 501, a bracket platform 503 is provided with the same moving direction as the translation push rod 502. A concave conveyor seat 504 is installed on the bracket platform 503. After a single round bottle 11 reaches the end of the product conveyor belt 501, the bracket platform 503 moves forward, causing the round bottle 11 to tilt backward and laterally into the conveyor seat 504, ensuring that each round bottle 11 can be tilted in a specific direction.

[0046] Limiting baffles 506 are provided on the upper left and right sides of the product conveyor belt 501. Telescopic baffles 507 are provided at the ends of the limiting baffles 506, and the translation push rod 502 is located on the side of the corresponding telescopic baffle 507 away from the limiting baffles 506. The limiting baffles 506 ensure that the round bottles 11 are transported vertically on the product conveyor belt 501 to facilitate connection with upstream round bottle 11 filling equipment. The telescopic baffles 507 can block subsequent round bottles 11 after a single round bottle 11 enters the end of the product conveyor belt 501, preventing multiple round bottles 11 from colliding and hindering the lateral tilting of a single round bottle 11.

[0047] Downstream of the bag opening mechanism 4, above the suction conveyor belt 3, is a bag sealing mechanism 6. The bag sealing mechanism 6 includes a symmetrically arranged hot-cutting blade 601 and a heat-insulating pad 602. Both the hot-cutting blade 601 and the heat-insulating pad 602 are connected to a lifting linkage 603. A telescopic suction pipe 604 is provided between the hot-cutting blade 601 and the heat-insulating pad 602. To improve the sealing effect of the bagged product, the bag sealing mechanism 6 can be configured to extract and seal the air from the space outside the round bottle 11 inside the packaging bag 10.

[0048] Above the suction conveyor belt 3, corresponding to the travel between the bag opening mechanism 4 and the bag sealing mechanism 6, a translation gripper 7 is provided. The translation gripper 7 includes a translation base 701, a lifting platform 702, and a gripping gripper 703. The lifting platform 702 is mounted on the translation base 701, and the gripping gripper 703 is mounted on the bottom of the lifting platform 702. An inner recessed sleeve 704 is provided on the inner side of the gripping gripper 703. Since the bagged round bottle 11 is laid horizontally on the suction conveyor belt 3, if the suction conveyor belt 3 is used to directly transport the bagged round bottle 11 forward to the bag sealing mechanism 6, the round bottle 11 is prone to rolling and shifting when the suction conveyor belt 3 starts and stops, causing the bag sealing mechanism 6 to fail to align the bag opening. To avoid the above problem, the translation gripper 7 is set to directly grip the bagged round bottle 11 to the bag sealing mechanism 6 to ensure accurate alignment. The concave sleeve 704 can be set to correspond to the size of the round bottle 11, ensuring that when the gripper 703 clamps the round bottle 11, the round bottle 11 can be fixed between the concave sleeves 704 on both sides.

[0049] The bag storage mechanism 1 includes a circulating conveyor belt 101 with multiple bag storage compartments 102. The bag retrieval mechanism 2 is located above the bag storage compartments 102 on the top of the circulating conveyor belt 101, near the side of the suction conveyor belt 3. Because the bag storage mechanism 1 has multiple bag storage compartments 102, workers can continuously add packaging bags 10 to the bag storage compartments 102 behind the one currently being retrieved, without the equipment stopping due to the need to add packaging bags 10, resulting in high work efficiency.

[0050] The suction conveyor belt 3 has multiple ventilation holes 301, and multiple vertically downward suction fans 302 are horizontally arranged inside the suction conveyor belt 3. The evenly arranged multiple suction fans 302 can ensure that the objects placed on the suction conveyor belt 3 are subjected to uniform suction force, thereby improving the stability of the objects placed on the suction conveyor belt 3.

[0051] During operation, individual packaging bags 10 are retrieved one by one from the bag storage mechanism 1 by the bag retrieval mechanism 2, and transported by the suction conveyor belt 3 to the bag opening mechanism 4. The suction cup assembly and the round support assembly open the bag and hold the opening path. Then, a single upright round bottle 11 is transported by the bag filling mechanism 5 to the rear of the round support assembly and tilted laterally. The translation push rod 502 pushes the round bottle 11 into the packaging bag 10 along the opening path. Finally, the round support assembly closes and exits, and the suction cup assembly releases, completing the automatic bottling operation. Subsequent processes include direct product output or vacuuming and sealing the packaging bags 10 of the round bottles 11 using the translation gripper 7 in conjunction with the sealing mechanism 6.

[0052] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
