[0013] In one embodiment, the stop structure is provided with a stop portion for stopping the product, and the height of the stop portion from the first conveyor belt is h1, where 10mm≤h1≤35mm.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0026] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 4 This application provides a bag-flipping device 100, which includes a first conveying component 10 and a second conveying component 20. The first conveying component 10 includes a first conveyor belt 11 that conveys products along a first direction; the second conveying component 20 includes a second conveyor belt 21 that conveys products along the first direction; along the second direction, the second conveyor belt 21 is spaced apart from the first conveyor belt 11, and along the height direction, the second conveyor belt 21 is lower than the first conveyor belt 11.

[0028] In related technologies, products on the first conveyor belt 11 are usually flipped over manually and placed on the second conveyor belt 21 for transport. This method is labor-intensive, inefficient, and costly. Alternatively, products on the first conveyor belt 11 can be flipped over to the second conveyor belt 21 by air blowing. However, this method is only suitable for lightweight products and cannot be used when flipping other non-lightweight products, thus limiting its applicability.

[0029] Therefore, the flipping device 100 of this application also includes a flipping component 30, which includes a pushing structure 31 and a stop structure 32. The pushing structure 31 is located above the first conveyor belt 11, thereby causing the product to flip towards the second conveyor belt 21. The stop structure 32 is located on the side of the first conveyor belt 11 along the second direction close to the second conveyor belt 21. The stop structure 32 is used to stop the lower end of the product. When the pushing structure 31 pushes the product, the stop structure 32 exerts a force on the product in the opposite direction to the pushing structure 31, causing the upper end of the product to flip towards the second conveyor belt 21 and the lower end of the product to flip towards the pushing structure 31. With the cooperation of the pushing structure 31 and the stop structure 32, the upper and lower ends of the product are simultaneously subjected to forces with opposite forces and equal values, causing the product to flip around its own center of gravity from the first conveyor belt 11 to the second conveyor belt 21, realizing 180° automated flipping of the product without manual intervention, which is beneficial to improving flipping efficiency. At the same time, it is also suitable for non-lightweight products and has a wide range of applications.

[0030] In summary, this application, through the setting of the flipping component 30 and the mutual cooperation of the pushing structure 31 and the stop structure 32, enables the product to complete a 180° automated flipping, which improves production efficiency and has a wide range of applications, making it suitable for different products.

[0031] It should be noted that the first direction, the second direction, and the height direction are set at angles to each other. In this application, the length direction of the first conveyor belt 11 is defined as the first direction, and the width direction of the first conveyor belt 11 is defined as the second direction. Next, the explanation will be based on the first direction as the x-axis, the second direction as the y-axis, and the height direction as the z-axis.

[0032] In one specific embodiment, the pushing structure 31 includes a rotating shaft 311 and blades 312 connected to the rotating shaft 311. The rotating shaft 311 can drive the blades 312 to rotate, so that the blades 312 can push the upper end of the product, causing the upper end of the product to flip towards the second conveyor belt 21. Thus, with the arrangement of the rotating shaft 311 and the blades 312, the structure is simple, and the blades 312 can regularly push the product by rotating the rotating shaft 311. Only the rotational speed of the rotating shaft 311 needs to be controlled, without the need for complex program control.

[0033] In other embodiments, the pushing structure 31 may also employ a periodically reciprocating push rod to push the upper part of the product.

[0034] like Figures 1 to 4 As shown, in a specific embodiment, multiple blades 312 are provided, and the multiple blades 312 are arranged circumferentially along the rotating shaft 311. In this way, the multiple blades 312 can sequentially and cyclically push the products continuously conveyed on the first conveyor belt 11 to ensure the product flipping efficiency.

[0035] like Figure 4 As shown, in a specific embodiment, the included angle between any two adjacent blades 312 along the circumference of the rotation axis 311 is α, where 90°≤α≤180°. This arrangement ensures a certain interval between adjacent blades 312, preventing interference with the product during its transport to the pushing structure 31, while allowing the product to be pushed and flipped by the blades 312 when it reaches its designated position. For example, α = 90°, 120°, or 180°.

[0036] In practical applications, if it is necessary to flip one of two adjacent products while leaving the other unflipped, there needs to be a sufficient gap between the two adjacent blades 312. This gap is necessary so that after one of the products is flipped by the blade 312, the circumferential gap between the blade 312 and the next blade 312 allows the next product to pass through the pushing structure 31, and the next blade 312 can then push and flip the next product, and so on.

[0037] In actual operation, the number and angle of blades 312 should be set according to the specific product, the product packaging form, the product size, the conveying speed of the first conveyor belt 11, and the rotation speed of the shaft 311.

[0038] In this application, the product is set as a three-piece milk tea cup. Taking the three-piece milk tea cup as an example, the flipping device 100 is defined. The length direction of the three-piece milk tea cup is consistent with the conveying direction of the first conveyor belt 11. One side of the three-piece milk tea cup along its own width direction is pushed by the pushing structure 31 on the upper end of the three-piece milk tea cup, and the other side is stopped by the stopping structure 32 on the lower end of the three-piece milk tea cup.

[0039] like Figure 1 As shown, in a specific embodiment, the stop structure 32 is provided with a stop portion 321, which is used to stop the three-cup milk tea container. The height of the stop portion 321 from the first conveyor belt 11 is h1, where 10mm ≤ h1 ≤ 35mm. If the height of the stop portion 321 is too low, the stopping effect may be insufficient, affecting the flipping of the lower end of the three-cup milk tea container. If the height of the stop portion 321 is too high, it may cause excessive stopping, affecting the 180° flipping effect of the three-cup milk tea container. Therefore, limiting the height of the stop portion 321 ensures the blocking effect on the three-cup milk tea container and promotes the flipping of the three-cup milk tea container. For example, h1 = 10mm, 20mm, or 35mm.

[0040] In a specific embodiment, the stop structure 32 has a support base and a stop rod. A support base is connected to each side of the stop rod along its axial direction. The support bases are installed on the first conveying assembly 10 to support the stop rod, which forms the aforementioned stop portion 321. In other embodiments, the stop portion 321 may also be a stop bar, a stop block, etc.

[0041] In a specific embodiment, the bag-flipping device 100 also includes a baffle. The baffle is vertically arranged along the height direction. Along the second direction, the baffle is located on the side of the second conveyor belt 21 away from the first conveyor belt 11, so as to prevent the milk tea triple cup from tipping over to the outside of the second conveyor belt 21 after flipping, and to have a righting effect on the milk tea triple cup.

[0042] like Figure 2 As shown, in a specific embodiment, the first conveyor belt 11 has a central axis, and along the second direction, the central axis of the first conveyor belt 11 is eccentrically arranged relative to the axis of the rotating shaft 311. Thus, since the distance between two adjacent blades 312 gradually increases radially outward along the rotating shaft 311, in order to reduce interference with the three-cup milk tea container, the ends of the blades 312 facing away from the rotating shaft 311 need to push the three-cup milk tea container. It is precisely this eccentric arrangement that allows the pushing structure 31 to push the three-cup milk tea container without requiring a high height, using the ends of the blades 312 facing away from the rotating shaft 311. This helps to shorten the height of the pushing structure 31, reduce space occupation, and facilitate the placement of more conveying devices on the upper layer of the packaging device 100.

[0043] like Figure 2 As shown, in a specific embodiment, the minimum height of the blade 312 of the pushing structure 31 from the first conveyor belt 11 is h2, and the height of the axis of the rotating shaft 311 from the first conveyor belt 11 is h3, where 0.45h3 ≤ h2 ≤ 0.7h3. This arrangement limits the contact range between the end of the blade 312 facing away from the rotating shaft 311 and the three-cup milk tea container, ensuring that the position of the blade 312 for pushing the three-cup milk tea container is not too close to the rotating shaft 311, thus avoiding interference with the three-cup milk tea container. Simultaneously, the position of the blade 312 for pushing the three-cup milk tea container is not too far off the rotating shaft 311, ensuring that the blade 312 has sufficient contact area and pushing force with the three-cup milk tea container. For example, h2 = 0.45h3, 0.56h3, or 0.7h3.

[0044] like Figure 2 and Figure 3As shown, in a specific embodiment, along the second direction, the distance between the axis of the rotating shaft 311 and the central axis of the first conveyor belt 11 is L1, and the width of the first conveyor belt 11 along the second direction is L2, where 0.25L2≤L1≤0.4L2. Specifically, L2 is the width dimension of the inner belt of the first conveyor belt 11. This ensures that the rotating shaft 311 is eccentrically positioned relative to the central axis of the first conveyor belt 11, so that the end of the blade 312 can push the three-piece milk tea cup. Simultaneously, it avoids the axis of the rotating shaft 311 being too far from the central axis of the first conveyor belt 11, which would cause the blade 312 to be too long, thus facilitating the rotation of the blade 312 and reducing power loss. For example, L1 = 0.25L2, 0.3L2, or 0.4L2.

[0045] like Figure 3 As shown, in a specific embodiment, the distance between the first conveyor belt 11 and the second conveyor belt 21 along the second direction is L3, where 40mm ≤ L3 ≤ 60mm. This creates a sufficient distance to facilitate the flipping of the three-cup milk tea container. Simultaneously, it ensures that the three-cup milk tea container falls precisely onto the second conveyor belt 21 after flipping. For example, L3 = 40mm, 50mm, or 60mm.

[0046] like Figure 1 As shown, in a specific embodiment, the height difference between the first conveyor belt 11 and the second conveyor belt 21 is h4, where 120mm ≤ h4 ≤ 160mm. Thus, by limiting the height difference between the first conveyor belt 11 and the second conveyor belt 21, a sufficient height is formed to ensure that the three-piece milk tea cup can complete a 180° rotation. Simultaneously, it also ensures that the three-piece milk tea cup lands precisely on the second conveyor belt 21 after the 180° rotation, avoiding over-rotation. For example, h4 = 120mm, 135mm, or 160mm.

[0047] In a specific embodiment, the flipping device 100 further includes a detector located upstream of the first conveyor belt 11 relative to the flipping assembly 30, along the conveying direction of the first conveyor belt 11, for detecting the three-pack of milk tea cups. Thus, the detector can detect the three-pack of milk tea cups and feed the detection signal back to the control center. The control center converts the detection signal into an action command to control the movement of the pushing structure 31, thereby achieving the flipping of the desired three-pack of milk tea cups. Specifically, a control board is set up to form the control center. Since the control procedures and methods are well known to those skilled in the art, they will not be described in detail here. For example, the detector can be a visual sensor or a weight sensor, etc.

[0048] In a specific embodiment, the first conveyor belt 11 and the second conveyor belt 21 can transport in the same direction along the first direction or in the opposite direction along the first direction.

[0049] like Figures 1 to 3As shown, in a specific embodiment, the first conveying component 10 further includes a first driving member 12, which provides power to the first conveyor belt 11. For example, the first driving member 12 can be a motor.

[0050] like Figures 1 to 3 As shown, in a specific embodiment, the second conveying assembly 20 further includes a second driving member 22, which provides power to the second conveyor belt 21. For example, the second driving member 22 can also be a motor or the like.

[0051] like Figures 1 to 4 As shown, in a specific embodiment, the flipping assembly 30 further includes a third driving member 33 and a transmission assembly 34. The transmission assembly 34 is drively connected between the third driving member 33 and the pushing structure 31 to transmit the power of the third driving member 33 to the pushing structure 31, thereby driving the rotating shaft 311 to rotate. For example, the transmission assembly 34 can be a belt assembly, and the third driving member 33 can be a motor. In other embodiments, the transmission assembly 34 can also be a gear assembly for transmission.

[0052] like Figures 1 to 4 As shown, in a specific embodiment, the flipping assembly 30 further includes a support frame 40, on which a pushing structure 31 is mounted to support the pushing structure 31.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
