Description

Technical Field

[0001] The present invention relates to the technical field of production lines, and particularly relates to an automatic bag - sleeving production line for woven bags. Background Art

[0002] Woven bags are widely used in the low - end packaging industry and are commonly used packaging supplies, such as for the packaging of cartons, rice, flour, and coatings. Since the woven bag itself has a breathable structure, it cannot be fixed by vacuum suction, and the material is relatively soft. Currently, manual bagging and bag - mouth sewing are generally used, resulting in low efficiency and high labor costs.

[0003] In the existing automatic bag - sleeving machines for woven bags in the current technology (such as the existing patent CN 205395283 U, "An Automatic Bag - Sleeving Machine for Woven Bags"), through the cooperation of the conveying and transferring mechanism of the packaged object and the conveying mechanism of the woven bag, the bagging of the product can be automatically completed. However, there are two technical difficulties to be solved in the existing bag - sleeving machines: one is how to quickly open the bag mouth of the woven bag? The other is how to achieve automatic bag sealing? The woven bags generally used in the existing automatic bag - sleeving machines are of an open - mouth structure, that is, one end is closed and the other end is open. The product is pushed in from the open - mouth side of the plastic - sealed bag, and then the woven bag is manually sealed and then transported together with the internal product to another processing process. The existing automatic bag - sleeving machines cannot meet the requirements. Due to the breathability of the woven bag, it is impossible to use the general vacuum adsorption method to pick up the bag, and it is difficult to easily open the bag mouth of the woven bag with the general bag - opening mechanism of the bag - sleeving machine, which greatly reduces the efficiency of packing the product into the bag.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The present invention adopts a structure that combines a material conveyor line, a finished product conveyor line, a pusher mechanism, a woven bag bin, a bag opening mechanism, a sewing mechanism, and a bag mouth clamping and displacement mechanism to realize the automated process of automatically opening and automatically sewing the bag mouth of woven bags. It also realizes functions such as automatically loading materials onto the bag and sleeving the bag, and can be connected to high-speed production lines in the prior art to achieve seamless connection, efficient bag sleeving, and automatic sealing.

[0025] 3. The material conveyor line cooperates with the flipping mechanism to realize flipping the material on the material conveyor line by 90° around the X direction, quickly sorting the materials, ensuring the bagging speed and efficiency, and preparing for pushing the materials into the bag. The flipping mechanism can also adopt an oil pressure buffer to eliminate impacts such as vibrations and collision damages in non-mechanical movements, greatly reducing noise, accelerating the mechanical operation frequency, and extending the mechanical life of the flipping mechanism.

In this embodiment, the sewing horizontal driving member 75 can be a motor.

[0076] As a further illustration of this embodiment, this embodiment further includes a control device provided with a human-machine interaction interface; the material conveying line 1, the flipping mechanism 2, the material pushing mechanism 3, the woven bag bin 4, the bag opening mechanism 6, the sewing mechanism 7, the carton palletizing robot 8, the finished product pushing mechanism 9, and the bag mouth clamping displacement mechanism 10 are respectively connected to the control device.

This chip has powerful performance and very rich peripheral interfaces. The control device further 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 an unmanned state. The working process of the watchdog chip is as follows: The STM32F103C8T6 chip sends signals to the watchdog chip at regular intervals through an I / O pin; if the single-chip program accidentally runs wild and cannot send signals to the watchdog chip at regular intervals, at this time, the watchdog chip will send a reset signal to reset the STM32F103C8T6 chip, causing the program to execute from the beginning. In this way, the automatic reset of the control device is realized.

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

The data acquisition module is connected to the STM32F103C8T6 chip, and the STM32F103C8T6 chip is connected to the edge computing module of the control device. 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 there are abnormalities in the monitoring data, the STM32F103C8T6 chip sends out abnormal alarm information to the human-machine interaction interface and the Internet of Things management platform. The charge-coupled device image sensor CCD is made of a highly sensitive semiconductor material, which can convert light into electric charges, convert them into digital signals through an analog-to-digital converter chip, and the digital signals are stored by the flash memory or the built-in hard disk card inside the camera after compression. Therefore, it can easily transmit the data to the 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 invention, 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 woven bag images taken by the three CCD sensors. Preprocessing the obtained woven bag images includes:

[0081] V1. Scale and crop the woven bag image to obtain a woven bag image M1 of a specified size.

[0082] V2. Preprocess the obtained woven bag including: adjusting the clarity of the woven bag to improve the clarity level of the woven bag and obtaining the preprocessed woven bag M2;

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

[0084] Convert the preprocessed woven bag from the RGB color space to the grayscale space, where the grayscale feature conversion function used is:
