Description

Technical Field

[0001] The utility model relates to the technical field of packaging reversing equipment, in particular to a packaging reversing mechanism based on vision. Background Art

[0002] In the modern packaging industry, the efficient operation of automated production lines is the key to improving production efficiency and ensuring product quality. Especially when handling flat packaging bottles, these containers are widely used in food, cosmetics, pharmaceuticals and other fields due to their unique shape design (such as lower center of gravity and larger surface area ratio), which puts higher requirements on the precise control of the packaging process. However, traditional packaging bottle reversing equipment faces a series of technical challenges and defects when handling flat packaging bottles. These problems are mainly manifested in the following aspects:

[0003] 1. Insufficient positioning accuracy: Traditional reversing devices rely on fixed paths and position control of mechanical structures. For flat packaging bottles of various shapes and sizes, it is difficult to achieve accurate positioning and stable guidance, which can easily cause the bottles to tilt, collide or even fall during the reversing process, affecting production efficiency and product appearance.

[0004] 2. Limited adaptability: Due to design limitations, traditional equipment is often difficult to flexibly adapt to flat packaging bottles of different sizes and materials. It is not able to respond adequately to the rapid switching of product lines and diversified production needs, which increases the cost of equipment modification and maintenance.

[0005] 3. Efficiency and energy consumption: When processing flat packaging bottles, traditional reversing equipment requires more physical contact and fixing devices, which not only consumes more energy, but also can only be reversed one by one, and the reversing efficiency is low.

[0006] In view of the above problems, it is particularly urgent to explore a more intelligent, flexible and efficient solution for flat packaging bottle reversing.

[0007] To this end, we propose a vision-based packaging reversing mechanism. Utility Model Content

[0041] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0042] like Figure 1-Figure 2 As shown, this embodiment describes in detail a vision-based packaging reversing mechanism, which includes a conveying mechanism 100, a turntable 200, an optical camera 400, a telescopic mechanism 500, a suction cup assembly 600 and other parts.

[0043] like Figure 1 and Figure 2 As shown, the conveying mechanism 100 in this embodiment adopts a chain conveyor belt, which has a stable conveying capacity and a precise conveying speed. The surface of the conveyor belt is provided with an anti-skid texture to ensure that the packaging bottle 800 does not slide during the conveying process. A stopper 101 is connected to the end of the conveying mechanism 100 to block the packaging bottle 800 and prevent it from sliding off the conveyor belt, and at the same time to facilitate the positioning, grabbing and reversing of the last packaging bottle 800.

[0044] like Figure 1 and Figure 2 As shown, there are two turntables 200 in this embodiment and they are symmetrically distributed on both sides of the conveying mechanism 100. The two turntables 200 can be used to center and determine the spacing of the packaging bottles 800. The spacing between the two turntables 200 is greater than and infinitely close to the width of the packaging bottles 800, ensuring that the packaging bottles 800 move one by one under the rotation of the turntables 200, and because the rotation speed of the turntables 200 is lower than the rotation speed of the conveying mechanism 100, a certain spacing can be left between the packaging bottles 800, which is convenient for the subsequent simultaneous grasping and reversing of multiple packaging bottles 800.

[0045] In another embodiment, a rotary drive device 201 is connected to the axis of the turntable 200 to drive the turntable to rotate. At the same time, the turntable 200 moves in a direction perpendicular to the conveying mechanism 100 through a slide rail 202 to accommodate packaging bottles of different widths. An adjustment handle 203 for adjusting the distance between the two turntables 200 is also provided on the slide rail 202, so that the operator can adjust the distance between the turntables according to actual conditions, thereby increasing the scope of application and being applied to different packaging bottles 800.

[0046] like Figure 1-Figure 2As shown, the optical camera 400 in this embodiment is placed above the conveying mechanism 100 on the rear side of the turntable 200, and is used to shoot the upper surface graphics of the packaging bottle 800. After the packaging bottle 800 is centered by the turntable 200, it is convenient to move the packaging bottle 800 to the bottom of the optical camera 400 to capture its graphics. The optical camera 400 has high resolution and fast imaging capabilities, and can accurately capture the graphic information of the packaging bottle 800. In order to improve the shooting effect, a fill light 300 is also provided between the optical camera 400 and the conveying mechanism 100 to illuminate the packaging bottle 800.

[0047] In this embodiment, there are two telescopic mechanisms 500, which can simultaneously position three packaging bottles 800 in cooperation with the stopper 101, and telescope toward the conveying mechanism 100. The driving shaft of the telescopic mechanism 500 is connected with a baffle 501 which is perpendicular to the side wall of the conveying mechanism 100. When the telescopic mechanism 500 is extended, the baffle 501 will block the packaging bottles 800 on the conveying mechanism 100 to prevent them from moving forward.

[0048] like Figure 1-Figure 2 As shown, the suction cup assembly 600 in this embodiment is the biggest innovation, and its structure includes a suction cup, a second rotation drive device 601, a sliding seat 603 and a second telescopic mechanism 602.

[0049] In this embodiment, there are three suction cup assemblies 600 and they cooperate with two telescopic mechanisms 1 200 and a stopper 101 to clamp and reverse three packaging bottles 800 at the same time, thereby improving work efficiency. This also relies on the turntable 200 to center the packaging bottles 800 and to space the packaging bottles 800 equidistantly, thereby facilitating subsequent grasping and reversing. The suction cup is connected to the upper surface of the packaging bottle 800 through negative pressure to achieve adsorption. The second rotation drive device 601 drives the suction cup to rotate through gear transmission, thereby changing the direction of the packaging bottle 800.

[0050] In this embodiment, the second rotary drive device 601 is electrically coordinated with the optical camera 400, and can receive the graphic signal transmitted by the optical camera 400, and adjust the direction of the packaging bottle 800 according to the signal content. The sliding seat 603 is used to support the second rotary drive device 601 to ensure its stable operation. The second telescopic mechanism 602 can drive the sliding seat 603 to move vertically, thereby adjusting the height of the suction cup to adapt to packaging bottles 800 of different heights, and can also lift the packaging bottle 800 and cooperate with the subsequent horizontal conveying mechanism 700 to transfer the packaging bottle 800 to other production lines.

[0051] The specific working principle is as follows:

[0052] The conveying mechanism 100 adopts a continuous conveyor belt design to ensure that the packaging bottle 800 moves forward at a constant speed. The turntables 200 are symmetrically distributed on both sides of the conveyor belt, and the spacing is set slightly smaller than the minimum width of the packaging bottle to ensure stable guidance of the bottle body when passing. The turntable 200 is driven by a rotary drive device 201, and its speed is lower than the conveyor belt to facilitate the smooth transition of the bottle body between the turntables. The optical camera 400 is installed above the conveyor belt behind the turntable, and cooperates with the fill light 300 to ensure that the upper surface graphics of the packaging bottle can be clearly photographed even in poor light conditions. The graphic information is stored in real time and transmitted to the control system for analyzing the orientation and position of the bottle body.

[0053] When the direction needs to be changed, the baffle 501 of the telescopic mechanism 1 500 is extended to temporarily block the bottle from moving forward. At the same time, the suction cup assembly 600 accurately adjusts the position of the suction cup through the rotation drive device 2 601 according to the image signal transmitted by the optical camera 400, absorbs the bottle and rotates it to the required direction. After this process is completed, the telescopic mechanism 1 500 is retracted, and the bottle continues to move forward on the conveyor belt.

[0054] Meanwhile, in this embodiment, the spacing adjustment and position optimization function of the turntable 200 is particularly emphasized.

[0055] The introduction of the adjustment handle 203 allows the operator to quickly adjust the turntable spacing according to the packaging bottles of different specifications, ensuring that bottles of all sizes can pass smoothly between the turntables, reducing jamming and wear. In addition, through precise measurement and calculation, the midpoints of the two turntables 200 are aligned with the center line of the conveying mechanism 100, ensuring the symmetry and stability of the bottles during the reversing process.

[0056] In this embodiment, the packaging bottles 800 can be transported to a suitable position after the change of direction, and multiple packaging bottles 800 can be simultaneously transported by multiple suction cup assemblies 600. The automated horizontal and vertical movement of this embodiment demonstrates the integrated application of the horizontal conveying mechanism 700 and the telescopic mechanism 2 602.

[0057] In another embodiment, the horizontal conveying mechanism 700 not only fixes the telescopic mechanism 2 602, but also automatically adjusts the horizontal position of the suction cup assembly 600 according to the position of other equipment on the production line, thereby achieving more flexible layout adaptability. The rotary drive device 3 701 drives the horizontal conveying mechanism to ensure that the suction cup assembly is accurately in place before the packaging bottle that needs to be reversed arrives. At the same time, the vertical movement function of the telescopic mechanism 2 602 enables the suction cup assembly 600 to adapt to packaging bottles of different heights on the conveyor belt, thereby increasing the versatility of the equipment. This design optimizes the space utilization efficiency during the reversing process and reduces the reversing failure caused by height mismatch. Summary Through the detailed description of the above embodiments, the vision-based packaging reversing mechanism of the present invention demonstrates its advantages in improving the flexibility, accuracy and adaptability of automated production lines. From optical recognition to precise reversing, and then to a flexible adjustment mechanism, each link has been carefully designed to ensure the smooth conversion of packaging bottles during high-speed production, thereby improving production efficiency and product quality. This invention is suitable for various packaging industries, especially production lines with strict requirements for reversing packaging bottles.
