Description

Technical Field

[0001] This utility model relates to bagging machines, and in particular to a bagging device for automatically bagging packaging bags. Background Technology

[0002] It is known that during product packaging, smaller products are often placed inside larger containers for easier handling and transport. To save on packaging costs, manufacturers simply stack products inside packaging bags and then seal the edges. However, once the bags are stretched open, they lack a fixed restraining structure, requiring manual adjustment of the internal space to fit products. This not only results in low packaging efficiency but also makes products prone to scattering and damage during stacking due to the lack of restraining mechanisms. Furthermore, different packing personnel use different stacking methods, leading to inconsistent overall shapes after packaging and preventing neat stacking.

[0003] The industry has thus adopted the method of inserting packaging bags into containers, using the containers to limit the product placement and ensure neat stacking. For example, Taiwan's utility model patent No. M440262 discloses a reverse-insertion carton bagging machine. This machine first uses a bagging device to insert the bag onto the carton, then conveys it to a pressing mechanism. The pressing mechanism uses a pressure plate to fix the bag opening, and then an inserting plate presses the bottom of the packaging film bag against the bottom of the carton, achieving automated reverse bagging. However, the bagging process requires multiple mechanisms, increasing equipment configuration costs and failing to meet production cost control requirements. The bag insertion cannot be completed in one step, reducing production efficiency. Although the inserting plate of the pressing mechanism can press the bottom of the packaging film bag to the bottom of the carton, the upward airflow generated when the inserting plate rises carries the bag upwards as well, causing the bottom of the packaging film bag to fail to adhere to the carton. Furthermore, when the pressure plate is pressed, it also fixes the bag opening. If the pressure plate accidentally gets stuck on the packaging film bag, the bag opening is fixed and there is no room for adjustment or release. The bag body is easily pulled and torn by the pressure plate, affecting the packaging effect.

[0004] Therefore, how to improve the above-mentioned problems is the primary issue that this utility model aims to solve. Utility Model Content

[0005] The main purpose of this utility model is to provide a bagging device that requires fewer mechanisms, reduces equipment configuration costs, completes bagging in one step, improves production efficiency, and uses airflow to guide the packaging bag into the container in the reverse direction, thus solving the problem of packaging bags being easily torn.

[0006] To achieve the aforementioned objectives, the present invention adopts the following technical solution:

[0007] A bagging device comprising:

[0008] A conveying structure for conveying a container to a certain position, the container having an air intake hole penetrating its bottom;

[0009] A bag-feeding structure is positioned above the positioning point of the conveying structure to supply the packaging bag to be fitted onto the container;

[0010] A bag structure is provided below the bag feeding structure and above the positioning point of the conveying structure. Two base plates that can be moved up and down by power are symmetrically provided. Each base plate has a mounting plate that can be moved relative to each other by power on the opposite side. Each mounting plate has several suction cup assemblies for adsorbing and expanding the packaging bag so that the packaging bag can be placed on the opening end of the container.

[0011] The feature is that it further includes an air suction structure, which is located below the conveying structure corresponding to the positioning point. The air suction structure has an air suction pipe, which is opposite to the air suction hole at the bottom of the container located at the positioning point. The air suction pipe is connected to an air suction source, and the air suction source causes the air suction pipe to generate suction force, thereby sucking the packaging bag into the container.

[0012] Preferably, the conveying structure includes a plurality of spaced rollers that can be driven by a power source to rotate in the same direction.

[0013] Preferably, the air intake structure is further provided with a lifting component, which drives the air intake pipe to move up and down along the axial direction. When the container is transported to the positioning point, the lifting component drives the air intake pipe to move upward through the space between two adjacent rollers and abut against the air intake hole at the bottom of the container.

[0014] Preferably, the air intake is provided with a baffle plate having a plurality of air-permeable holes.

[0015] Preferably, when the container is transported to the positioning point, the air suction structure and the bagging structure are activated synchronously.

[0016] Preferably, each mounting plate of the bagging structure is provided with an air blowing pipe, and each air blowing pipe can generate airflow through an air blowing source to blow the packaging bag into the container.

[0017] The beneficial effects of this utility model, specifically, as can be seen from the above technical solution, are mainly achieved by using the suction structure in conjunction with the suction hole at the bottom of the container to generate suction force to draw the packaging bag into the container, thereby realizing one-step packaging bag insertion, improving bagging efficiency, solving the problem of packaging bags being easily torn, and achieving the effect of reducing production costs.

[0046] Locating point P Detailed Implementation

[0047] Please see Figures 1 to 7 This is a preferred embodiment of the bagging device provided by the present invention, which mainly includes a conveying structure 1, a bag feeding structure 2, a bagging structure 3, and a suction structure 4, wherein:

[0048] Please see Figure 1 and Figure 6 As shown, the conveying structure 1 is for conveying a container 5 to a fixed position P. Preferably, it is equipped with several rollers 11 arranged at intervals, which can be driven by a power source to rotate in the same direction. These rollers 11 can be arranged at intervals along the same direction to form a conveying structure 1 with a single conveying direction, or they can be arranged at intervals to form a circle to form a conveying structure 1 with cyclical transmission. In this invention, a positioning sensor 12 can sense whether the container has reached the positioning point P and trigger the bag-feeding structure 2 to convey the packaging bag 22, and the bag-covering structure 3 and the suction structure 4 are activated simultaneously. The positioning sensor 12 can be an infrared sensor or a mechanical blocking device; in this invention, an infrared sensor is preferred.

[0049] The bag feeding structure 2 is positioned above the positioning point P of the conveying structure 1 to supply the packaging bag body 22 to be fitted onto the container 5. The bag feeding structure 2 has a power-driven rotating roll 21 on which a plurality of packaging bags 22 are wound. Rotation of the roll 21 releases the packaging bags 22 downwards. The bag fitting structure 3 is positioned below the bag feeding structure 2 and above the positioning point P of the conveying structure 1. Wherein, as... Figures 2 to 4 As shown, the bagging structure 3 is symmetrically provided with two base plates 32 that can be moved up and down by a power device 31. Each base plate 32 has a mounting plate 33 on its opposite side that can be moved relative to each other by the power device 31. Each mounting plate 33 has several suction cup assemblies 34 facing each other. These suction cup assemblies 34 move closer together with the two mounting plates 33 to attract the packaging bag 22 released between the two mounting plates 33, and then move further apart with the two mounting plates 33 to open the packaging bag 22. In this utility model, each mounting plate 33 is symmetrically provided with two suction cup assemblies 34 to apply force evenly to open the packaging bag 22, avoiding the packaging bag 22 from being torn due to uneven force. The two base plates 32 can move downward to put the opened packaging bag 22 onto the opening end of the container 5.

[0050] Each mounting plate 33 of the bag-covering structure 3 is also provided with an air blowing pipe 35. Each air blowing pipe 35 can generate airflow through an air source (not shown in the figure) to blow air onto the packaging bag body 22, causing the packaging bag body 22 to sink into the container 5, ensuring that the suction structure 4 accurately and quickly adsorbs the packaging bag body 22, so that the packaging bag body 22 is completely covered in the container 5.

[0051] To further explain, such as Figure 1 , Figure 6 and Figure 7 As shown, the suction structure 4 is positioned below the conveying structure 1 at the corresponding positioning point P. The suction structure 4 has a suction pipe 41, which is opposite to the suction hole 51 at the bottom of the container 5 located at positioning point P. The suction pipe 41 is connected to a suction source 42. The suction source 42 generates suction in the suction pipe 41, thus drawing the packaging bag 22, which is fitted onto the opening of the container 5, into the container 5, completing the bagging process. The outer diameter of the suction end of the suction pipe 41 that abuts against the suction hole 51 is greater than or equal to the inner diameter of the suction hole 51, ensuring that the suction pipe 41 completely covers the suction hole 51 and generates sufficient suction to draw the packaging bag 22 downwards into the container 5. Preferably, the suction hole 51 of the container 5 is provided with a baffle 52 with multiple perforated holes to separate the packaging bag 22 from the suction pipe 41, preventing the packaging bag 22 from being drawn into the suction pipe 41 and causing bagging failure. These ventilation holes can be square, round or other shapes, and this utility model does not limit them.

[0052] The suction structure 4 preferably includes a lifting member 43, which drives the suction pipe 41 to move up and down axially. When the container 5 is transported to the positioning point P, the lifting member 43 drives the suction pipe 41 to move upward and pass between two adjacent rollers 11, and abut against the suction hole 51 at the bottom of the container 5, so as to improve the tightness between the suction pipe 41 and the suction hole 51, and ensure that there is enough suction to suck the packaging bag 22 into the container 5 to complete the bagging action.

[0053] Based on the overall structure described above, the operating principle of this utility model in practical applications will be further explained. For example... Figure 1 and Figure 6As shown, the roller 11 of the conveying structure 1 rotates to transport a container 5 to the positioning point P. After the sensing device 12 senses that the container is in place, it triggers the roll 21 of the bag-making structure 2 to rotate, releasing the packaging bag 22 downwards between the two mounting plates 33 of the bagging structure 3. At this time, the bagging structure 3 and the suction structure 4 start synchronously. As shown in Figures 2 and 3, the two mounting plates 33 of the bagging structure 3 are driven to move closer together, causing the suction cup components 34 to adhere to the packaging bag 22. The two mounting plates 33 then move away from each other, and the suction cup components 34 maintain the state of adhering to the packaging bag 22 and move with the two mounting plates 33, thereby opening the packaging bag 22. At the same time, as shown in Figure 7, the lifting component 43 of the suction structure 4 drives the suction pipe 41 to move upwards through the space between the two adjacent rollers 11 and abut against the suction hole 51 at the bottom of the container 5. The suction source 42 is activated, causing the suction pipe 41 to generate suction force on the inside of the container 5.

[0054] Then as Figure 4 As shown, the bag feeding structure 2 cuts the packaging bag body 22 with the cutting component 23, and the two base plates 32 of the bag covering structure 3 move downwards so that the packaging bag body 22 is fitted into the opening of the container 5. As shown in Figure 5, each air blowing pipe 35 blows air into the packaging bag body 22, causing the packaging bag body 22 to sink into the container 5. Simultaneously, it is attracted by the suction force generated by the suction pipe 41, so that the packaging bag body 22 is completely fitted into the container 5, thus completing the fitting of the packaging bag body 22.

[0055] The bagging structure 3 releases the packaging bag 22 from adsorption and resets. The air source 42 of the air suction structure 4 stops operating. The air suction pipe 41 is driven by the lifting component 43 to move down and separate from the container 5. The conveying structure 1 restarts and outputs the bagged container 5. The next container 5 to be bagged is then conveyed to the positioning point P, and the next round of bagging operation can be carried out.

[0056] In summary, the bagging structure provided by this utility model achieves the following improvements:

[0057] First, it simplifies the process and improves production efficiency. The positioning point of the container is provided with an air suction structure below the conveying structure, and the bottom of the container is provided with an air suction hole corresponding to the air suction structure, so that when the packaging bag is put into the opening end of the container, it is simultaneously sucked into the container, so that the packaging bag is completely put into the container.

[0058] Secondly, the airflow guides the packaging bag into place, reducing the packaging bag loss rate. This utility model utilizes an air blowing pipe to blow air from above the packaging bag and an air suction device to absorb air from below the packaging bag, so that the airflow guides the already stretched packaging bag into the container from top to bottom. This replaces the traditional bagging machine's mechanical method of pressing the bag in with an insertion plate, solving the problem that mechanical pressing easily stretches and deforms the packaging bag, thus reducing the packaging bag loss rate.

[0059] Third, the inserted packaging bag fits the container better; this utility model uses airflow guidance instead of mechanical pressing to completely suck the packaging bag into the container and further discharge the gas between the packaging bag and the container, so that the packaging bag fits the container better. This solves the problem that the up-and-down movement of the insertion plate of the traditional bagging machine causes airflow disturbance, which causes the packaging bag to be pulled out and unable to fit the container.

[0060] The above embodiments are disclosed only to illustrate the present utility model and are not intended to limit the present utility model. Any substitution of equivalent components should still fall within the scope of the present utility model.

[0061] In summary, this invention enables those skilled in the art to understand that it can indeed achieve the aforementioned objectives, and thus complies with the provisions of the Patent Law. Therefore, this application is filed in accordance with the law.
