Abstract
Description
Technical Field
[0001] This utility model relates to the field of labeling machine production and design technology, specifically to an automatic correction device for labeling machines. Background Technology
[0002] Existing labeling machines achieve automatic correction mainly by relying on the coordinated work of sensor detection, control system and mechanical actuator. Its core logic is to monitor the label position deviation in real time and dynamically adjust the labeling parameters. The sensors used are usually photoelectric sensors.
[0003] During the labeling process, due to production needs, the sizes of the items to be labeled are inconsistent. To ensure the correction effect, the position of the photoelectric sensor needs to be adjusted vertically. However, the installation position of the photoelectric sensor is divided into inside and outside the machine. Adjusting inside the machine requires disassembling and assembling the machine, which is more complicated and results in long downtime of the device. Adjusting outside the machine requires opening the clamping parts, grasping the sensor to adjust it up and down, and closing the clamping parts. There are many repetitive operations, which reduces the debugging efficiency and has limitations.
[0004] The reason for this problem is that when debugging the sensor, if it is debugged inside the machine, the machine panel or protective cover must be disassembled to access the sensor. The space for tool access is limited, and adjacent modules need to be disassembled, which increases downtime. If it is debugged outside the machine, the sensor fixing clamps need to be loosened. During the adjustment process, the sensor needs to be continuously supported to prevent it from falling. After the adjustment is completed, it needs to be locked again and the tightening torque needs to be verified. The whole process needs to be repeated 4-6 steps, which reduces debugging efficiency. Therefore, we propose an automatic correction device for labeling machines to solve the above problems. Utility Model Content

[0032] A photoelectric sensor 12 is disposed on one side of the crossbar 11 and is used to scan the position of the label. A drive unit 13 is disposed inside the crossbar 11 and is connected to the photoelectric sensor 12. The drive unit 13 is used to drive the photoelectric sensor 12 to move vertically.
[0033] A labeling component is provided on one side of the crossbar 11, and an adjusting component 2 is provided on the back of the labeling component. The adjusting component 2 is used to adjust the height of the labeling component. The adjusting component 2 includes a fixed base 21, an extension column 22, and a drive motor 23.

[0034] In this embodiment, when the device is in use, the product is conveyed along the conveyor belt.

[0035] Example 2
[0036] This utility model discloses an automatic correction device for a labeling machine. More specifically, based on Embodiment 1, it is provided according to the appendix... Figure 1 , 4 As shown in Figure 5, it includes a correction unit 1, which includes a crossbar 11, a photoelectric sensor 12, and a driving component 13.
