Description

Technical Field

[0001] The utility model relates to the technical field of intelligent manufacturing or shoemaking, in particular to an automatic shoe tongue labeling device with a shoe tongue taking and placing unit. Background Art

[0002] In the shoemaking industry, shoe tongue hot labeling is a part of the production process. The shoe tongue is the part between the bottom of the shoelace and the top of the instep, which plays a role in reducing the friction between the shoelace and the instep. Generally, the shoe tongue is a separate piece of material on the upper. Usually, the label with the brand's LOGO or QR code is printed on the shoe tongue. The shoe tongue labeling device is an automated device that can add labels to the shoe tongue. Its existence can greatly improve the mechanization and automation of shoemaking.

[0003] In the existing technology, a technical solution has been proposed, which uses visual recognition technology to automatically determine the position and orientation of the tongue, and uses a parallel robot to place the label, thereby achieving alignment between the tongue and the label. Using this technology, the position, angle and type of the tongue can be automatically identified, so there is no need to place the tongue in a standardized manner, because even if the tongue is placed at an angle, the parallel robot can be used to adjust the angle of the label so that the tongue and the label are aligned.

[0004] However, the above-mentioned automatic shoe tongue labeling device still has a bottleneck in the number of hot labels that can be applied per unit time. This is because the shoe tongue is randomly supplied to the conveyor and finally supplied to the bottom of the parallel robot at a randomly oriented angle. The parallel robot needs to perform a relatively large movement to match the angle of the shoe tongue. The parallel robot needs more time to perform the above operation, thus affecting the efficiency of the shoe tongue labeling device. In addition, the parallel robot needs to perform complex actions, resulting in a complex structure of the parallel robot, and high manufacturing and later maintenance costs. Utility Model Content
