Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for material processing, and in particular to a label rejection device. Background Technology

[0002] In the processing of materials such as packaging boxes, labels need to be affixed to the surface of the materials to achieve the identification function. However, during the affixing process, labels may be misaligned, wrinkled, or damaged, resulting in non-conforming products. Therefore, non-conforming labels on the materials must be removed to ensure product quality.

[0003] When processing manually, operators need to identify the labels on the surface of the materials one by one, manually peel off the unqualified labels and collect them. This method is not only labor-intensive and inefficient, but also prone to missing or accidentally tearing qualified labels due to human fatigue and judgment errors. It is difficult to adapt to the cycle time requirements of large-scale production lines. Therefore, a label rejection device is now provided. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 The label rejection device includes a mounting plate 1. An electric push rod 2 and an L-shaped connecting column 9 are mounted on the lower end of the mounting plate 1. A U-shaped plate 4 is connected to the lower end of the electric push rod 2. An L-shaped lifting plate 3 is connected to the lower end of the vertical sections on both sides of the U-shaped plate 4. A first telescopic cylinder 10 is mounted on one side of the vertical section of the L-shaped lifting plate 3. A negative pressure adsorption component is connected to one end of the first telescopic cylinder 10. A second telescopic cylinder 8 is connected to the lower end of the horizontal section of the L-shaped connecting column 9. A rejection blade 6 is connected to the lower end of the second telescopic cylinder 8.

[0021] The negative pressure adsorption assembly includes a suction nozzle 12, one side of which is connected to an air suction pipe 13, and one end of the air suction pipe 13 is connected to an external suction fan.

[0022] The top of the suction nozzle 12 is fixed with a T-shaped slider 17, and the horizontal section of the L-shaped lifting plate 3 has a strip hole 11. The T-shaped slider 17 is slidably engaged with the strip hole 11.

[0023] The lower end of the vertical section of the L-shaped connecting column 9 is connected to a U-shaped mounting frame 5, and the lower ends of the vertical sections on both sides of the U-shaped mounting frame 5 are connected to waste collection grooves 7.

[0024] The upper half of the scraper 6 is vertical, while the lower half is slanted. A proximity sensor 14 (model: Lion Precision LRD6300) is installed on one side of the outer wall of the suction nozzle 12. A controller 15 (model: H3U-1616MR-XP) is installed on the top of the mounting plate 1. The proximity sensor 14 and the electric push rod 2 are both electrically connected to the controller 15. The first telescopic cylinder 10 and the second telescopic cylinder 8 form a control link with the controller 15 through solenoid valves. The controller 15 is electrically connected to the solenoid valves of the first telescopic cylinder 10 and the second telescopic cylinder 8.

[0025] When the material conveyed by the production line arrives at the label rejection station, the proximity sensor 14 installed on the outer wall of one side of the suction nozzle 12 detects the material signal and transmits the signal to the controller 15. The controller 15 issues a command to stop the material conveying of the production line and complete the material positioning. Controller 15 controls the electric push rod 2 to start, the electric push rod 2 extends and pushes the U-shaped plate 4 to move downward, the U-shaped plate 4 drives the L-shaped lifting plate 3 to descend synchronously until the suction nozzle 12 is close to the material surface; The controller 15 controls the external suction fan to start, and a negative pressure is formed at the suction nozzle 12 through the suction pipe 13. The suction nozzle 12 tightly adsorbs the unqualified label. Then the controller 15 controls the electric push rod 2 to retract, which drives the material away from the conveyor line. The controller 15 controls the first telescopic cylinder 10 to start via a solenoid valve, causing the first telescopic cylinder 10 to push the suction nozzle 12 to one side of the U-shaped mounting frame 5, the material to the bottom of the U-shaped mounting frame 5, and the material label to the bottom of the scraper 6. During this process, the T-shaped slider 17 at the top of the suction nozzle 12 maintains a sliding limit along the strip hole 11 of the horizontal section of the L-shaped lifting plate 3 to ensure that the suction nozzle 12 moves smoothly.

[0026] The controller 15 controls the second telescopic cylinder 8 to start via a solenoid valve. The second telescopic cylinder 8 extends and pushes the scraper 6 downward. Since the upper part of the scraper 6 is vertical and the lower part is inclined, the inclined blade gradually cuts into the surface of the label and the material after contacting the edge of the label. At the same time, with the suction force of the suction nozzle 12, the defective label is completely peeled off from the surface of the material, thereby pressing the label into the waste collection tank 7 below. After the label is peeled off, the controller 15 controls the first telescopic cylinder 10 and the second telescopic cylinder 8 to retract and reset, and the suction nozzle 12 and the scraper 6 return to their initial positions. At the same time, the controller 15 issues a command to resume material conveying on the production line, and the device enters the next scrap removal cycle.

[0027] Example 2 is an optimization based on Example 1, specifically: Mounting holes 16 are provided at the four corners of the mounting plate 1. Using the pre-set mounting holes 16 at the four corners of the mounting plate 1, the entire label rejection device is fixed to the designated work position on the production line by bolts and other fasteners, ensuring that the mounting surface is flat and stable, avoiding shaking when the device is working, so that the L-shaped lifting plate 3 is located above the material conveying line.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
