Description

Technical Field

[0001] The present invention relates to the technical field of bagging machines, and particularly relates to an automatic self-adhesive bag bagging device. Background Art

[0002] With the development of technology, the production capacity of various automated production lines in factories is gradually increasing. After the products are produced, they need to be packaged and protected with sealed bags to make them waterproof and dustproof. Self-adhesive bags are commonly used packaging supplies. There is a self-adhesive strip at the bag mouth of the self-adhesive bag. Generally, after the self-adhesive bag is attached to the bag mouth, it can be torn open and used repeatedly, and it is suitable for packing some items that do not need to be sealed. Self-adhesive bags are generally prefabricated bags, and manual bagging is mostly used in the market, which is not only slow in efficiency but also inconsistent in appearance.

[0003] In the existing automatic bagging machines (such as the existing patent CN 115231055, a continuous automatic bagging machine with the function of inserting self-adhesive bags and zipper bags), the automatic bagging of products can be completed through the cooperation of the conveying and transferring mechanism of the packaged objects and the conveying mechanism of the plastic-sealed bags. However, there are two technical difficulties that need to be solved in the existing bagging machines: one is how to quickly open the bag mouth of the self-adhesive bag? The other is how to automatically tear off the adhesive strip at the bag mouth of the self-adhesive bag and smooth the bag mouth to ensure the consistency of the product appearance?

[0004] The plastic-sealed bags generally used in the existing automatic bagging machines are of an open-mouth structure, that is, one end is closed and the other end is open. The product is pushed into the plastic-sealed bag from the open side, and then the plastic-sealed bag together with the internal product is conveyed to another processing process. However, some products need to be packaged with self-adhesive bags, and the existing automatic bagging machines cannot meet the requirements. The bag-opening mechanism of the general bagging machine cannot easily open the bag mouth of the self-adhesive bag. Therefore, before the product is put into the bag, the adhesive strip at the bag mouth needs to be torn open manually, and then the existing bagging machine can be used to push the product into the self-adhesive bag. This step greatly reduces the efficiency of packaging the product into the bag.

[0005] Therefore, in view of the situation that the bag mouth needs to be opened manually when using self-adhesive bags to be applicable to the bagging machine, a new type of bagging machine is developed to realize the full-automatic plastic-sealing packaging of products with self-adhesive bags. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The utility model adopts a bag taking mechanism, a bag opening mechanism, a self-adhesive bag strip tearing mechanism, a self-adhesive bag smoothing mechanism, and a finished product conveyor line to realize the automatic process of self-adhesive bag automatic bag opening-strip tearing-sealing; the utility model also adopts a material handling belt line, a side push feeding mechanism, a feeding conveyor line, and a servo pushing mechanism to realize the functions of automatic bagging, bagging and sealing of materials, and the single-channel beat can generally reach more than 1200 bags / hour.

Then, the first scraping plate horizontal driving component drives the scraping plate vertical driving component and the scraping plate to displace outward along the Y direction to tear off the glue strip.

The control device also includes a watchdog chip connected to the STM32F103C8T6 chip. During the operation of the STM32F103C8T6 chip, it will be interfered by the outside world such as electromagnetic fields, which will cause the program to run wild and fall into an infinite loop. The purpose of using the watchdog chip is to monitor the operation status of the single-chip microcomputer in real time and enable it to work continuously in the unmanned state. The working process of the watchdog chip is as follows: the STM32F103C8T6 chip sends signals to the watchdog chip regularly through an I / O pin; if the single-chip program execution accidentally runs wild and cannot send signals to the watchdog chip regularly, at this time, the watchdog chip will send a reset signal to reset the STM32F103C8T6 chip, so that the program will execute from the beginning. In this way, the automatic reset of the control device is realized.

[0078] As a further improvement to the present utility model, the control device further includes an SX1278ZTR4-GC wireless module connected to the STM32F103C8T6 chip.

Its special LoRa debugging method can greatly increase the communication distance and can be widely used in the short-distance Internet of Things wireless communication field of various occasions. It has the characteristics of small size, low power consumption, long transmission distance, and strong anti-interference ability. The STM32F103C8T6 chip is connected to the Internet of Things management platform through the SX1278ZTR4-GC wireless module to achieve remote human-computer interaction.

The third CCD sensor is provided on the glue strip rack 91 and is oriented towards the finished product conveyor belt 81. The second CCD sensor is oriented towards the finished product conveyor belt 81 and is used to collect the bag-sealing image of the self-adhesive bag. The three CCD sensors (i.e., the first CCD sensor, the second CCD sensor, and the third CCD sensor) are respectively connected to the data acquisition module of the control device. The data acquisition module is connected to the STM32F103C8T6 chip, and the STM32F103C8T6 chip is connected to the edge computing module. The three CCD sensors transmit the digital signals of the images to the edge computing module through the data acquisition module; the edge computing module is used to analyze and process the received monitoring data. When it analyzes that the monitoring data is abnormal, the STM32F103C8T6 chip sends out an abnormal alarm message to the human-computer interaction interface and the Internet of Things management platform. The charge-coupled device image sensor CCD is made of a high-sensitivity semiconductor material. It can convert light into electric charges, convert them into digital signals through an analog-to-digital converter chip, and the digital signals are saved by the flash memory or built-in hard disk card inside the camera after compression. Therefore, it can easily transmit the data to a computer and, with the help of the computer's processing means, modify the image according to needs and imagination.

[0080] As a further improvement to the present utility model, in order to improve the accuracy of the edge computing module in analyzing and processing the received image monitoring data, it is necessary to preprocess the self-adhesive bag images captured by 3 CCD sensors. Preprocessing the obtained self-adhesive bag images includes:

[0081] V1. Scale and crop the self-adhesive bag image to obtain a self-adhesive bag image M1 with a specified size.

[0082] V2. Preprocess the obtained self-adhesive bag M1, including: adjusting the clarity of the self-adhesive bag to improve the clarity level of the self-adhesive bag, and obtaining the preprocessed self-adhesive bag M2;

[0083] V3. The image obtained by the CCD sensor camera is a color image. In order to reduce the computational complexity and complexity of image processing, it is necessary to convert the color image into a grayscale image, that is, perform grayscale processing on the preprocessed self-adhesive bag M2, specifically including:

[0084] Convert the preprocessed self-adhesive bag from the RGB color space to the grayscale space, and the grayscale feature conversion function used is:

[0085]

[0086] In the formula, f(x, y) represents the pixel brightness value of the pixel point (x, y) in the grayscale image, and r(x, y), g(x, y), and b(x, y) respectively represent the grayscale values of the pixel point (x, y) in the R, G, and B channels. The R, G, and B component values; represents the maximum value among the R, G, and B component values of the pixel point (x, y), represents the minimum value among the R, G, and B component values of the pixel point (x, y), and μ1 and μ2 represent the set weight factors, where μ1 + μ2 = 1, μ1 ∈ [0.7, 0.9], and μ2 ∈ [0.1, 0.3];

[0087] Calculate the grayscale values of each pixel point in the self-adhesive bag respectively to obtain a grayscale feature image.

[0088] V4. Enhance the pixel brightness value f(x, y) of the pixel point (x, y) to obtain g(x, y), that is, f(x, y) and g(x, y) are the grayscale values before and after the pixel contrast enhancement at the position of the pixel point (x, y), respectively. The minimum value of the original image gray level is represented by s1, and the maximum value of the gray level is represented by s2; after linear mapping, the minimum value of the enhanced image gray level is t1, and the maximum value is t2. The edge computing module analyzes and processes the obtained g(x, y).
