Abstract
Description
Technical Field
[0001] This invention belongs to the field of packaging technology, specifically relating to an over-packaging data collection device. Background Technology
[0002] Excessive packaging refers to packaging that exceeds the normal functional requirements for product protection, display, storage, and transportation. It is mainly manifested in excessive packaging layers, excessively large packaging gaps, excessively high packaging costs, inappropriate material selection, and packaging weight ratio exceeding the standard.
[0003] In 2021, the state issued the mandatory national standard GB 23350-2021, which stipulates the technical requirements for packaging void ratio, number of packaging layers, and packaging cost of food and cosmetics, covering 31 categories of food, including pastries, wine, tea, beverages, and health food.
[0004] Compared to other food products, the problem of excessive packaging for mooncakes and zongzi (sticky rice dumplings) remains relatively prominent, with issues such as excessive packaging layers and large gaps between packages. Some even involve the use of expensive materials and the mixing of high-value goods, necessitating further refinement and tightening of packaging requirements for mooncakes and zongzi. To streamline mooncake and zongzi packaging and facilitate their marketability, the State Administration for Market Regulation (Standardization Administration), together with the Ministry of Industry and Information Technology and other departments, organized relevant packaging standardization technical committees and technical institutions to formulate and issue Amendment No. 1 to the national standard "Requirements for Restricting Excessive Packaging of Commodities: Food and Cosmetics" (GB 23350-2021). Amendment No. 2 was issued in April 2024, which included requirements for tea packaging and incorporated the weight coefficient of some commodity packaging into the scope of excessive packaging standards.
[0005] Currently, there is no complete and efficient over-packaging detection device on the market. Therefore, it is urgent to develop a detection device and program system that covers the requirements for all aspects of packaging in standard GB 23350-2021 and its first and second amendments. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an over-packaging data acquisition device.
[0007] The technical problem solved by this invention is achieved through the following technical solution: An over-packaging data acquisition device includes a weight acquisition unit, an image acquisition unit, and a data processor installed inside a box. The weight acquisition unit is installed at the center of the bottom plate of the box. The data processor is arranged around the weight acquisition unit and connected to it. The weight acquisition unit includes a worktable, a servo motor rotation mechanism, an X-shaped mounting plate, and a pressure sensor. Two layers of the X-shaped mounting plates are installed on the bottom plate, and the pressure sensor is arranged between the X-shaped mounting plates. The servo motor rotation mechanism is installed on the upper X-shaped mounting plate. The worktable is rotatably mounted on the servo motor rotation mechanism, and the packaged items are placed on the worktable. The image acquisition unit is installed on the side panel of the housing. The image acquisition unit includes two parallel slide rails, on which sliders are slidably installed. A mounting plate is connected between the sliders. A U-shaped clamp is rotatably installed on the mounting plate. A binocular camera is clamped on the U-shaped clamp. The binocular camera swings with the U-shaped clamp. The binocular camera is connected to the data processor.
[0008] Furthermore, the pressure sensor is located at the center of the X-shaped mounting plate.
[0009] Furthermore, limit blocks are provided at both the upper and lower ends of the slide rail.
[0010] Furthermore, the workbench is equipped with several positioning posts.
[0011] The advantages and beneficial effects of this invention are as follows: 1. The over-packaging data acquisition device of this invention covers more than 90% of the packaging materials to be tested in the market, replacing the shortcomings of traditional manual calculation and the long time required for 3D scanning. It can quickly collect the volume and weight of the packaging materials, and has high measurement accuracy and is easy to operate.
[0012] 2. This invention utilizes programmed statements to transform the extensive parameter information in the formulas and tables of the standard into a program that can intelligently determine whether packaging is excessive. It directly determines whether packaging is excessive with a single click, saving the manual calculation process of selecting parameters according to the standard, greatly reducing manpower and manual calculation errors.

Detailed Implementation
[0014] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not limiting, and should not be used to limit the scope of protection of the present invention.
[0015] like Figure 1 , 2 As shown, an over-packaging data acquisition device is innovative in that it includes a weight acquisition unit, an image acquisition unit, and a data processor 8 installed inside a box. The weight acquisition unit is installed at the center of the bottom plate 7 of the box. The data processor 8 is arranged around the weight acquisition unit and connected to it. The weight acquisition unit includes a worktable 1, a servo motor rotation mechanism 2, an X-shaped mounting plate 3, and a pressure sensor 4. Two layers of the X-shaped mounting plates 3 are installed on the bottom plate, and the pressure sensor 4 is arranged between the X-shaped mounting plates 3. The pressure sensor 4 is located at the center of the X-shaped mounting plate 3. The servo motor rotation mechanism 2 is installed on the upper X-shaped mounting plate 3, and the worktable 1 is rotatably mounted on the servo motor rotation mechanism 2. The worktable 1 is provided with several positioning posts 11, and the packaged items are placed on the worktable 1 through the positioning posts 11. The image acquisition unit is installed on the side panel of the housing. The image acquisition unit includes two parallel slide rails 5. A slider is slidably installed on the slide rails 5. Limit blocks 10 are provided at both the upper and lower ends of the slide rails 5. A mounting plate 9 is connected between the sliders. A U-shaped clamp 6 is rotatably installed on the mounting plate 9. A binocular camera is clamped on the U-shaped clamp 6. The binocular camera swings with the U-shaped clamp 6. The binocular camera is connected to the data processor 8.
[0016] The data collected by the above data acquisition device (two-dimensional images from the binocular camera and packaging weight from the pressure sensor) is transmitted to each data processor 8. After data processing, a three-dimensional image is generated. If a complete three-dimensional image is not generated, the relevant data acquisition device will continue to complete image acquisition. This process continues until all images of the packaging are acquired, and the volume and weight of the packaging are output.
[0017] The data processor 8 completes the two-dimensional image acquisition of the packaged item to be tested by controlling the image acquisition device (binocular camera) and the rotating platform 2. Based on the two-dimensional images under different vision, the three-dimensional coordinates and images of the item to be tested are obtained through the binocular camera algorithm. The volume data of the item to be tested can be obtained by the three-dimensional reconstruction, and the weight data of the packaged item to be tested can be directly acquired through the pressure sensor.
[0018] The over-packaging calculation program in this invention utilizes the powerful data editing capabilities of Excel. Its logical algorithm extracts and calculates the necessary space coefficients, packaging void ratio formulas, packaging costs, number of packaging layers, and packaging weight ratios for all food and cosmetic product categories in standard GB 23350-2021 and its first and second amendments. This is done through a logical language and by retrieving data from corresponding tables. The program automatically imports the volume and weight data obtained from the over-packaging data acquisition device, directly determining whether a product is over-packaged. Figure 3 , 4 As shown.
[0019] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
