Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically to a double-sided labeling machine that visually identifies the label position and automatically adjusts the equipment parameters. Background Technology
[0002] In the modern packaging industry, labeling machines are widely used in the packaging process of various products to accurately affix labels to the surface of product packaging. For cardboard box packaging, the demand for double-sided labeling is increasing. Because there are many different sizes of outer cartons for products with large feet, and each carton requires two labels (symmetrically positioned), manual labeling is laborious. Using traditional labeling machines requires frequent parameter adjustments, necessitating two separate processes or even two separate machines to complete the labeling of a single carton. Furthermore, traditional labeling machines struggle to adapt to different carton sizes. When changing carton sizes, significant time and effort are required to adjust the equipment structure, leading to low production efficiency. On the other hand, the lack of effective position detection and automatic adjustment mechanisms during the labeling process easily results in labels being applied crookedly, off-center, or even incorrectly in place, affecting the aesthetics of the product packaging and the accuracy of information delivery, increasing the defect rate and production costs. Therefore, there is an urgent need for a double-sided labeling machine that can automatically adapt to different carton sizes, accurately identify label positions, and automatically adjust equipment parameters.

The industrial control computer 33 has built-in image processing algorithms and machine learning models for processing the information collected by the industrial camera 31.
[0037] The labeling component 4 includes two label feeding components 41 and 42 respectively disposed on the upper and lower sides of the conveyor belt 1. The label feeding components 41 and 42 are used to affix labels to appropriate positions on the carton.
[0038] The label feeding component 41 includes a label feeding tray 411, a tensioning device 412, a buffer roller 413, a guide roller 414, a paper receiving tray 415, a peeling plate 416, a motor 417, and a photoelectric sensor 418.

[0039] The adjustment component 5 includes a PLC controller 51 and a transmission component 52. The PLC controller is connected to the industrial computer 32 via a 232 communication interface. The transmission component 52 is connected to the upper labeling component 41 and the lower labeling component 42 and is used to adjust the labeling position of the upper labeling component 41 and the lower labeling component 42.
[0040] The transmission component 52 includes a lead screw 521 and a fixed rod 522. The fixed rod 522 is disposed on both sides of the lead screw 521. The end of the lead screw 521 is connected to a drive motor 522, which is used to drive the lead screw 521 to adjust the position of the upper feed label 41 and the lower feed label 42.
[0041] The specific working process of this utility model:
[0042] When using the double-sided labeling machine of this utility model, firstly, cartons of different sizes are placed in the feeding bin 1. Then, the moving motor 13 is started, driving the threaded rod 12 to rotate, which in turn moves the moving baffle 11. The width of the inlet of the feeding bin 1 is automatically adjusted according to the size of the cartons, ensuring the cartons are stably placed within the feeding bin. After the fiber optic sensor 33 detects the cartons in place, it triggers the industrial camera 31 to acquire image information of the cartons and labels, and transmits the image information to the industrial control computer 32. The industrial control computer 32 uses built-in image processing algorithms and machine learning models to process and analyze the images, identifying the accurate position and orientation of the cartons and labels. The position information is then transmitted to the PLC controller 51 via a 232 communication interface. Based on the received position information, the PLC controller 51 controls the drive motor 523 to rotate, causing the lead screw 521 to rotate. This, in turn, drives the transmission component 52 to move through the lead screw and nut pair, thereby adjusting the positions of the upper and lower labeling components 41 and 42, ensuring the labeling assembly 4 is in the accurate labeling position. Simultaneously, the label paper on the label feeding tray 411, driven by the motor 417, passes sequentially through the tensioning device 412, buffer roller 413, and guide roller 414. Under the detection and control of the photoelectric sensor 418, it is accurately conveyed to the peeling plate 416. After the label is peeled off, the upper label feeding component 41 and the lower label feeding component 42 affix the label to the upper and lower surfaces of the carton respectively, achieving double-sided synchronous labeling of the carton. Throughout the labeling process, the vision recognition component 3 continuously monitors the position of the carton and the label. Once a positional deviation is detected, the information is promptly fed back to the adjustment component 5, which then readjusts the position of the labeling component 4 to ensure the accuracy and stability of the labeling process.
[0043] In summary, this invention, by incorporating a movable baffle and a moving motor, can automatically adjust the width of the feeding hopper inlet to accommodate cartons of different sizes, eliminating the need for frequent manual adjustments to the equipment structure and improving its versatility and production efficiency. Utilizing the industrial camera, fiber optic sensor, and industrial computer within the vision recognition component, it can collect and process the positional information of the cartons and labels in real time. Combined with built-in image processing algorithms and machine learning models, it accurately identifies the position and orientation of the cartons and labels, providing data support for precise labeling. The adjustment component, through a PLC controller and transmission components, can automatically adjust the position of the labeling component based on feedback from the vision recognition component, achieving precise label application and avoiding problems such as misaligned or off-center labeling, thus improving labeling quality and reducing product defect rates. The double-sided labeling component enables simultaneous labeling on both sides of the cartons, further improving labeling efficiency and meeting the demands of the modern packaging industry for high-efficiency production.
