Description

Technical Field

[0001] This invention relates to the field of packaging bottle production equipment technology, and in particular to an automatic bagging machine and bagging method. Background Technology

[0002] In the complete production process of bottle packaging, packaging the produced bottles is a crucial step. After completing manufacturing processes such as molding, the bottles need to be transported to an assembly plant to be assembled with other components such as caps and labels, ultimately forming a complete product for the market. During transportation, the bottles face many risks that may damage their appearance, thus requiring packaging. Among various packaging materials, plastic bags are widely used for individual bottle packaging due to their unique performance advantages.

[0003] Currently, commonly used plastic packaging bags on the market are usually flat, and for ease of storage and transportation, these bags are stacked in a pile. While this storage method saves space to some extent, it causes great inconvenience to subsequent bagging operations. Because each plastic bag is very thin and tightly fitted together, it is difficult to quickly and accurately separate individual bags when handling them manually, let alone open the bag opening smoothly.

[0004] Therefore, operators need certain work experience and skills to improve bagging efficiency. For example, when opening the bag, it's necessary to use the appropriate force and angle to avoid tearing the bag or failing to open it completely; when placing bottles into the bag, it's crucial to ensure the bottles enter accurately and the bag opening is sealed smoothly. However, newly hired employees, lacking practical experience, often require a considerable amount of training and practice to master these skills, which undoubtedly increases the company's labor costs and training time.

[0005] Furthermore, as the scale of bottle production continues to expand, production speed is also constantly increasing. To meet this production speed and ensure timely packaging, companies need to assign multiple workers to bagging operations simultaneously. This not only increases labor costs but also, due to individual differences in manual operation, makes it difficult to maintain consistent speed and quality among workers, potentially leading to instability in the entire production process. Moreover, prolonged, repetitive bagging work can easily cause worker fatigue, reducing work efficiency and product quality, further impacting the company's production profitability. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide an automatic bagging machine and bagging method to solve the problems of difficulty in opening plastic packaging bags and low efficiency of manual bagging.

[0007] An automatic bagging machine includes a frame and a conveying device located on one side of the frame for transporting bottles. A bagging area is provided on one end of the frame near the conveying device. A limiting mechanism for restricting the packaging bags is located below the bagging area, and a bag-opening mechanism for opening the bag opening is located above the bagging area. A feeding mechanism for pushing packaged bottles out of the bagging area is located on one side of the bagging area. A feeding mechanism for feeding stacks of packaging bags into the limiting mechanism is also provided on the frame. The bagging area is connected to the conveying device, which is further equipped with a pushing mechanism for pushing bottles into the bagging area and into the packaging bags. The bag opening mechanism includes an adsorption component and an air blowing component. The adsorption component is located above the bagging area to adsorb the packaging bag, and the air blowing component is located diagonally above the opening of the packaging bag to blow air into the opening of the packaging bag. The adsorption component first adsorbs the edge near the bag opening upwards to open part of the opening. Then, the blowing component blows air into the bag opening to make the plastic bag completely open. Next, the pushing mechanism pushes the bottle into the bagging area, and the bottle slides into the open packaging bag due to inertia. The adsorption assembly includes a mounting plate connected to the frame, a telescopic device fixed to the mounting plate, a suction cup body connected to the telescopic end of the telescopic device, and a vacuum pump connected to the suction cup body via an air pipe. The adsorption surface of the suction cup body faces downward, and the telescopic device can drive the suction cup body to move up and down. The air blowing assembly includes a fixed base connected to the frame, an air nozzle mounted on the fixed base, and an air pump connected to the air nozzle via an air pipe. The air outlet of the air nozzle points to the opening of the packaging bag.

[0008] Based on the above-described automatic bagging machine, the present invention also provides a bagging method for the automatic bagging machine, comprising: S1-Feeding: Place the stack of packaging bags in the sliding channel on the support base, start the second drive, and the second drive will drive the pusher plate to push the stack of packaging bags in the sliding channel to the top of the tray; S2-Limit: Start the lifting device to raise the pallet and send the stack of packaging bags into the receiving cavity of the limiting cover for limiting. Then the lifting device controls the lifting and lowering according to the number of bottles packaged per minute, so that the upper surface of the packaging bag is always within the bagging area. S3 - Open Bag: Start the first driver and adjust the adsorption component to the appropriate position. The telescopic device moves the suction cup body downwards and closer to the packaging bag. At the same time, the vacuum pump works to make the suction cup body adsorb the edge of the packaging bag near the bag opening. Then the telescopic device retracts to open the bag opening. S4 - Air Blowing: When the telescopic device retracts, it generates an electrical signal and transmits the signal to the air pump of the air blowing assembly. This controls the air pump to release compressed air, and the nozzle blows air into the opening of the packaging bag, thus opening the bag. S5-Bottle Push: When the transmission seat transfers the bottle between the guide seat and the push rod, a push signal is generated, which triggers the push rod to make a push action, pushing the bottle on the transmission seat along the guide seat into the packaging bag in the bagging area; S6 - Unloading: The pushing end of the pusher extends and pushes the packaged bag containing the bottle out of the bagging area along the guide groove, completing the unloading process.

[0009] The beneficial effects of this invention are: The automatic bagging machine of this invention realizes the automation of bottle packaging. From the feeding, limiting, opening, and blowing of the packaging bag to the pushing of the bottle and the final unloading, the whole process does not require much manual intervention, which greatly shortens the packaging time of a single bottle, improves production efficiency, and can meet the needs of expanding the scale of bottle production and increasing production speed.

[0010] Furthermore, it solves the problem of requiring multiple workers to operate simultaneously for manual bagging, reducing the company's labor input. At the same time, new employees can quickly learn to operate the equipment without extensive training and practice, further reducing the company's labor costs and training time.

[0011] Finally, manual operation suffers from individual differences; different workers cannot maintain consistent operating speed and quality, and prolonged repetitive work can easily lead to worker fatigue, affecting product quality. This automatic bagging machine operates stably, effectively avoiding these problems, ensuring stable and consistent packaging quality, and improving the company's production efficiency.

Detailed Implementation

[0013] This invention provides an automatic bagging machine and a bagging method. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0014] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0015] Please see Figures 1 to 7 : This embodiment discloses an automatic bagging machine, including a frame 1 and a conveying device 2 disposed on one side of the frame 1 for transporting bottles. A bagging area 3 is provided on one end of the frame 1 near the conveying device 2. A limiting mechanism 4 for restricting the packaging bags is provided below the bagging area 3, and a bag-opening mechanism 5 for opening the bag opening is provided above the bagging area 3. A feeding mechanism 6 for pushing the packaged bottles out of the bagging area 3 is also provided on one side of the bagging area 3. In addition, a feeding mechanism 7 is provided on the frame 1 for feeding stacks of packaging bags into the limiting mechanism 4; the bagging area 3 is connected to... The conveying device 2 is also equipped with a pushing mechanism 8 that pushes the bottle into the bagging area 3 and into the packaging bag. The working principle is as follows: the limiting mechanism 4 appropriately presses and limits the two sides of the packaging bag, and the top of the packaging bag is located in the bagging area 3. Then, the bag opening mechanism 5 first sucks the edge near the bag opening upward to open part of the opening. Then, air is blown into the bag opening to open the plastic bag. Next, the pushing mechanism 8 pushes the bottle into the bagging area 3 and slides into the open packaging bag under the action of inertia. Finally, the unloading mechanism 6 pushes the bottle out of the bagging area 3 for unloading.

[0016] In this embodiment, as Figure 2 As shown, the bag opening mechanism 5 includes an adsorption component 51 and an air blowing component 52. The adsorption component 51 is positioned above the bagging area 3 for adsorbing the packaging bag, and the air blowing component 52 is positioned diagonally above the opening of the packaging bag for blowing air into the opening of the packaging bag. Specifically, the adsorption component 51 includes a mounting plate 511 connected to the frame 1, a telescopic device 512 fixed to the mounting plate 511, a suction cup body 513 connected to the telescopic end of the telescopic device 512, and a vacuum pump connected to the suction cup body 513 through an air pipe. The adsorption surface of the suction cup body 513 faces downward, and the telescopic device 512 can drive the suction cup body 513 to move up and down. The telescopic device 512 is preferably a telescopic cylinder. When the vacuum pump is working, it can generate air on the adsorption surface of the suction cup body 513. A negative pressure is generated, which, in conjunction with the telescopic device 512, moves the suction cup 513 downwards to approach the packaging bag for adsorption. The vacuum pump and suction cup 513 are common components on the market, and their specific structures and working principles will not be described in detail. The vacuum pump is not shown in the attached drawings. In addition, the air blowing assembly 52 includes a fixed base 521 connected to the frame 1, an air nozzle 522 installed on the fixed base 521, and an air pump connected to the air nozzle 522 through an air pipe. The air outlet of the air nozzle 522 points to the opening of the packaging bag. The air pump can store compressed gas and spray gas through the air nozzle 522 when needed. The air pump is a common component on the market, and its specific structure and working principle will not be described in detail. The air pump is not shown in the attached drawings.

[0017] Furthermore, such as Figure 3As shown, the adsorption component 51 is also equipped with a displacement sensor 515. The displacement sensor 515 is specifically set at the telescopic end of the telescopic device 512. When the telescopic device 512 drives the suction cup body 513 to adsorb the packaging bag, it will generate an electrical signal through the displacement sensor 515 and transmit the electrical signal to the air pump of the air blowing component 52. The air pump can be controlled to release compressed air once through the electrical signal. That is, the adsorption component 51 and the air blowing component 52 are controlled and linked through the displacement sensor 515. Every time the adsorption component 51 adsorbs the packaging bag, the air blowing component 52 blows air once.

[0018] In this embodiment, as Figure 4 As shown, the limiting mechanism 4 includes a limiting cover 41 disposed below the bagging area 3 and a lifter 42 disposed below the limiting cover 41. The limiting cover 41 includes a vertically connected receiving cavity 411, limiting plates 412 located on both sides of the receiving cavity 411, and two pressing edges 413 located on both sides of the top of the receiving cavity 411. The top of the receiving cavity 411 is connected to the bagging area 3, and the width of the receiving cavity 411 corresponds to the width of the packaging bag. The two pressing edges 413 are connected to the limiting plates 412. At the top, the lifting end of the lifting device 42 is also provided with a tray 421. The feeding mechanism 7 pushes the stacked packaging bags onto the tray 421. Then, the lifting device 42 drives the tray 421 to rise, thereby sending the packaging bags into the receiving cavity 411. At this time, the limiting plate 412 limits the two sides of the stacked packaging bags, while the two pressing edges 413 press against the two sides of the top of the stacked packaging bags. By setting the limiting plate 412 and the pressing edges 413, the packaging bags can be prevented from being blown apart or disordered. In addition, as the stacked packaging bags are used one by one, their thickness gradually decreases. Therefore, the lifting device 42 needs to gradually lift the packaging bags so that their upper surface is always within the bagging area 3. Specifically, after the lifting device 42 initially lifts the stacked packaging bags, the number of packaging bags consumed per minute is calculated based on the number of bottles packaged per minute, thus determining the rate at which the packaging bag thickness decreases. This rate of decrease in packaging bag thickness is the subsequent lifting speed of the lifting device 42, which is a telescopic cylinder. It should also be noted that the total number of packaging bags in each stack is the same. Therefore, the lifting device 42 resets when the corresponding number of bagging cycles is reached.

[0019] Furthermore, such as Figure 4 As shown, in order to facilitate the feeding of the packaging bag into the receiving cavity 411, guide edges 414 are provided at the bottom of the two limiting plates 412 respectively. The two guide edges 414 are respectively inclined outward to form a figure-eight flared structure. When the packaging bag placed on the tray 421 enters the receiving cavity 411 from bottom to top, it can be centered by the action of the guide edges 414.

[0020] Furthermore, such as Figure 4As shown, the feeding mechanism 6 includes a guide groove 61 disposed on one side of the bagging area 3 and a pusher 62 disposed on the other side of the bagging area 3. The top of the guide groove 61 is fixedly connected to one side of the limiting cover 41 and the groove surface is tangent to the top surface of the limiting cover 41. The bottom of the guide groove 61 is supported on the frame 1 by a support rod 611. The pusher 62 is fixedly connected to the other side of the limiting cover 41 by a support block 621, and the pushing end of the pusher 62 points to the top opening of the guide groove 61. The pusher 62 is a telescopic cylinder.

[0021] In this embodiment, as Figure 5 As shown, the frame 1 includes a support base 11 and support plates 12 respectively disposed at both ends of the support base 11. The two support plates 12 are parallel and longitudinally arranged. One of the support plates 12 is provided with a through hole 121 for the bottle to pass through. The bagging area 3 is disposed on the inner side of the support plate 12 and connected to the through hole 121. The fixing seat 521 is fixedly connected to the outer side of the support plate 12 with the through hole 121, and the limiting cover 41 is fixedly connected to the inner side of the support plate 12 with the through hole 121.

[0022] In addition, such as Figure 2 and Figure 3 As shown, the upper and lower parts of the two support plates 12 are respectively provided with two parallel sliding guide rods 13. The mounting plate 511 is slidably fitted on the two upper sliding guide rods 13 and connected to the first driver 15. The first driver 15 is fixed on the support plate 12 with through holes 121 and the driving end is connected to the mounting plate 511. The first driver 15 can drive the mounting plate 511 to slide along the two upper sliding guide rods 13 so as to adjust the relative position of the adsorption assembly 51. The feeding mechanism 7 is fitted on the two lower sliding guide rods 13. The feeding mechanism 7 specifically includes a push plate 71 slidably fitted on the two lower sliding guide rods 13 and a second driver 72 fixedly installed on the support plate 12. The second driver 72 is fixed on the support plate 12 without through holes 121 and the driving end is connected to the push plate 71. The second driver 72 drives the push plate 71 to slide along the two lower sliding guide rods 13. The first driver 15 and the second driver 72 are electric push rods or pneumatic push rods.

[0023] Furthermore, such as Figure 5As shown, the support base 11 is provided with a sliding channel 111 for stacked packaging bags to slide. The sliding channel 111 extends from the middle of the upper surface of the support base 11 towards the two end support plates 12. A lifting port 112 is also provided at one end of the support base 11 near the bagging area 3. The tray 421 is located within the lifting port 112, and its top plane is flush with the top surface of the support base 11. The upper part of the tray 421 is within the sliding channel 111. Stacked packaging bags are placed in the sliding channel 111 manually or mechanically. Then, the second drive 72 pushes the stacked packaging bags along the sliding channel 111 to above the tray 421 via the push plate 71. The lifting device 42 then lifts the tray 421. Therefore, the lifting device 42 is specifically fixed to the bottom of the support base 11 via a connecting seat 422. To keep the pallet 421 balanced, the lifter 42 and the connecting seat 422 are provided with two sets and symmetrically installed on both sides of the lifting port 112 at the bottom of the support seat 11. In addition, to improve the smoothness of the packaging bag sliding in the sliding channel 111, multiple sliding strips 113 extending along both ends are provided on the upper surface of the support seat 11 at the position corresponding to the sliding channel 111. When the packaging bag is placed in the sliding channel 111, the bottom surface of the packaging bag is supported by the multiple sliding strips 113, reducing the contact area between the packaging bag and the upper surface of the support seat 11, thereby reducing the sliding friction. In addition, the multiple sliding strips 113 can also play a certain guiding role. Furthermore, baffles 114 are provided on both sides of the conveying channel 111 to prevent the packaging bag from deviating from the conveying direction. The baffles 114 are fixed on the support seat 11.

[0024] In this embodiment, as Figure 6 As shown, the conveying device 2 includes a support 21 and a transmission mechanism 22 mounted on the support 21. The pushing mechanism 8 is located above the transmission mechanism 22. Specifically, the top of the support 21 is provided with a transmission channel 211. The transmission mechanism 22 includes a transmission wheel 221 rotatably mounted on the frame 1 and located at both ends of the transmission channel 211, a transmission bar 222 surrounding the transmission wheels 221 at both ends, a plurality of transmission seats 223 arranged on the transmission bar 222, and a drive motor 224 mounted on the frame 1 and connected to one of the transmission wheels 221. After the transmission bar 222 is mounted around the transmission wheels 221 at both ends, its upper edge is located inside the transmission channel 211. When the drive motor 224 drives the transmission wheel 221 to rotate, it drives the transmission seat 223 to move inside the transmission channel 211 through the transmission bar 222. The transmission seat 223 is provided with an arc-shaped groove 2231, and bottles can be placed on the transmission seat 223 for transmission by manual or mechanical means.

[0025] In addition, such as Figure 6As shown, the feeding mechanism 8 includes a feeding rod 81 disposed on the top of the frame 1 and located on one side of the conveying channel 211, and a guide seat 82 disposed on the frame 1 on the opposite side of the feeding rod 81. The guide seat 82, the feeding rod 81, and the filling area 3 are in the same straight line position. When the transmission seat 223 transmits the bottle between the guide seat 82 and the feeding rod 81, a feeding signal is generated, thereby triggering the feeding rod 81 to make a feeding action. The feeding rod 81 is a pneumatic push rod, so the feeding action here is the piston rod of the pneumatic push rod extending and then retracting, thereby pushing the bottle on the transmission seat 223 along the guide seat 82 into the packaging bag of the filling area 3; preferably, the feeding signal can be triggered by a displacement sensor.

[0026] Based on the above structure, this embodiment also provides a bagging method for the above-mentioned automatic bagging machine, including: S1-Feeding: Place the stack of packaging bags in the sliding channel 111 on the support base 11, start the second driver 72, the second driver 72 drives the pusher plate 71 to push the stack of packaging bags in the sliding channel 111 to the top of the tray 421 at a speed of 0.3-0.5m / s. The number of packaging bags in the stack is not less than 200 and not more than 500. In this embodiment, it is preferred to have 400. Not less than 200 is to ensure that the packaging bags have a certain toughness and weight after being stacked, so as to facilitate the pusher plate 71 to push them. Not more than 500 is to prevent the packaging bags from being stacked too high, which may cause them to collapse or interfere with the limiting cover 41 when pushed by the pusher plate 71.

[0027] S2-Limit: Start the lifting device 42 to drive the pallet 421 to rise, and send the stack of packaging bags into the receiving cavity 411 of the limiting cover 41 for limiting. Then, the lifting device 42 controls the lifting according to the number of bottles packaged per minute, thereby gradually raising the packaging bags so that the upper surface of the top layer of packaging bags is always within the bagging area 3.

[0028] S3 - Open Bag: Start the first driver 15 and adjust the adsorption component 51 to a suitable position. The telescopic device 512 drives the suction cup body 513 to move downward and close to the packaging bag. At the same time, the vacuum pump works to make the suction cup body 513 adsorb the edge of the packaging bag near the bag opening. Then the telescopic device 512 retracts to open the bag opening.

[0029] S4 - Air Blowing: When the telescopic device 512 retracts, an electrical signal is generated and transmitted to the air pump of the air blowing assembly 52, which controls the air pump to release compressed air. The air nozzle 522 blows air into the opening of the packaging bag, making the packaging bag open.

[0030] S5 - Bottle Push: When the transmission seat 223 transmits the bottle between the guide seat 82 and the push rod 81, the displacement sensor generates a push signal, triggering the push rod 81 (pneumatic push rod) to perform a push action, pushing the bottle on the transmission seat 223 along the guide seat 82 into the packaging bag in the bagging area 3.

[0031] S6 - Unloading: The pushing end of the pusher 62 (telescopic cylinder) extends, pushing the packaged bag containing the bottle out of the bagging area 3 along the guide groove 61, thus completing the unloading.

[0032] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.

10. A bagging method for an automatic bagging machine according to any one of claims 1-9, characterized in that, include: S1-Feeding: Place the stack of packaging bags in the sliding channel on the support base, start the second drive, and the second drive will drive the pusher plate to push the stack of packaging bags in the sliding channel to the top of the tray; S2-Limit: Start the lifting device to raise the pallet and send the stack of packaging bags into the receiving cavity of the limiting cover for limiting. Then the lifting device controls the lifting and lowering according to the number of bottles packaged per minute, so that the upper surface of the packaging bag is always within the bagging area. S3 - Open Bag: Start the first driver and adjust the adsorption component to the appropriate position. The telescopic device moves the suction cup body downwards and closer to the packaging bag. At the same time, the vacuum pump works to make the suction cup body adsorb the edge of the packaging bag near the bag opening. Then the telescopic device retracts to open the bag opening. S4 - Air Blowing: When the telescopic device retracts, it generates an electrical signal and transmits the signal to the air pump of the air blowing assembly. This controls the air pump to release compressed air, and the nozzle blows air into the opening of the packaging bag, thus opening the bag. S5-Bottle Push: When the transmission seat transfers the bottle between the guide seat and the push rod, a push signal is generated, which triggers the push rod to make a push action, pushing the bottle on the transmission seat along the guide seat into the packaging bag in the bagging area; S6 - Unloading: The pushing end of the pusher extends and pushes the packaged bag containing the bottle out of the bagging area along the guide groove, completing the unloading process.
