Description

Technical Field

[0001] This utility model relates to the field of automatic labeling equipment for self-adhesive labels, and in particular to a label feeding device that can visually inspect and reject self-adhesive labels. Background Technology

[0002] Automatic self-adhesive labeling machines are widely used in the packaging industry, such as food, dairy products, and beer and beverage industries. The label feeding device is an essential component of these machines. Its main function is to unwind the self-adhesive label rolls, peel off the labels one by one, rewind the backing paper, and work with other devices to automatically label the products.

[0003] Self-adhesive label rolls are made through printing, die-cutting and other processes. During the printing process, defective products are inevitable. Currently, the only way to detect defective labels is to rely on the inspection by the printing plant when the label leaves the factory.

[0004] Companies must ensure 100% accuracy in the automatic labeling process when packaging products. Defective labels or labels with incorrect information are not permitted. Even if incorrect labels are detected in later processes, they will still result in product waste and economic losses.

[0005] Existing label supply devices lack visual inspection and rejection capabilities. Therefore, there is an urgent need to add inspection and rejection functions to label supply devices to promptly remove unqualified labels or labels with incorrect batch information before labeling. Summary of the Invention

The visual inspection rejection assembly 100 is installed at the lower left corner of the substrate. The first label-pulling roller assembly 200 is installed on the right side adjacent to the visual inspection rejection assembly 100.

[0034] like Figure 1 Figure 2 Figure 3 As shown, the visual inspection and rejection assembly 100 mainly includes: a base plate 101, a servo motor 107 with a reduction gearbox, a drive transmission pair 106, a disc cam 105, a cam roller 119, a linear guide rail 113, a vertical plate 114, a slider 117, a connector 116, a stripping plate 115, an inspection camera 102, a camera bracket 103, an extension board 104, a square plate 109, and a connecting rod 108.

The servo motor 107 of the gearbox is fixedly installed on the square plate 109, and the square plate 109 is fixedly connected to the bottom of the base plate 101 via the connecting rod 108.

[0035] like Figure 3 Figure 4 As shown, the aforementioned visual inspection and rejection assembly also includes a reject receiving shaft 126, a bearing housing 123, a bearing 122, a belt drive pair 125, and a guide roller 120. The reject receiving shaft 126 is rotatably connected to the base plate 101 via the bearing 122 and bearing housing 123.

The guide roller 120 is adjacent to the reject receiving shaft 126 and is mounted perpendicularly to the base plate 101.

[0036] like Figure 4As shown, the process of removing defective labels is as follows: The self-adhesive label LA normally travels along the trajectory shown by the dotted line. The peeling plate 115 is in a retracted state, hidden in the elongated groove E of the guide roller 120. At this time, qualified labels are not peeled off and continue to travel after passing the guide roller 120. When the detection camera 102 detects a defective label LB that needs to be removed, the servo motor 107 is started, the peeling plate 115 extends, and travels along the path shown in the figure. The labels LA form an angle α, the defective label LB is peeled off, and the defective label receiving shaft 126 rotates counterclockwise under the synchronous action of the servo motor 107, carrying the defective label LB out.

One end of the tension spring 408 is connected to the sliding plate 406, and the other end is connected to the substrate 101.

[0039] The working process of this utility model is as follows:

[0040] The self-adhesive label roll is mounted on an unwinding reel. The first label-pulling roller assembly provides unwinding power to the self-adhesive label roll. As the unwound labels travel, each label is inspected individually by a camera; labels that fail inspection are rejected by a rejection stripper. Qualified labels continue traveling, and after passing the floating roller, the self-adhesive label is peeled off at the label peeler. The peeled self-adhesive label, with the assistance of other mechanisms, is then automatically labeled onto the product. The second label-pulling roller assembly is positioned after the label peeling arm, and a second label-pulling servo provides power to move the label backing paper. The label backing paper is collected by the rewinding reel assembly.
