Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent manufacturing or shoemaking technical field especially relates to a shoe tongue double -sided label device. BACKGROUND

[0002] In the shoemaking industry, shoe tongue ironing label is a link in the generation processing, and the shoe tongue is the component between the lower part of shoelace and the upper part of instep, which plays a role in reducing the friction between shoelace and instep. Generally, the shoe tongue is a separate piece of material on the upper part of the shoe, and usually, the label carrying the LOGO or two-dimensional code information of the brand of the shoe is printed on the shoe tongue. The shoe tongue label device is an automatic equipment that can add labels to the shoe tongue, which can greatly improve the mechanization and automation degree of shoemaking.

[0003] In the existing technology, a technical solution has been proposed, which automatically determines the position and orientation of the shoe tongue by using visual recognition technology, and uses a parallel robot to place the label, so as to realize the alignment of the shoe tongue and the label. Referring to Chinese patent application CN202321332776.4. By using this technology, the position and angle of the shoe tongue can be automatically recognized, so that the shoe tongue can be placed regularly, because even if the shoe tongue is placed obliquely, the angle of the label can be adjusted by using the parallel robot, so that the shoe tongue and the label are aligned. In addition, Chinese patent applications CN202421568370.0 and CN202421570440.6 respectively disclose an automatic shoe tongue label device with a shoe tongue taking and placing unit and a shoe tongue supplying unit, which can regularly place the shoe tongue on the conveyor, so that the shoe tongue is kept in the same orientation, and the shoe tongue is no longer disordered, and the shoe tongue can also be regularly stored and supplied, i.e. the shoe tongue can be stored in the same orientation.

[0004] The blanking process of the shoe tongue causes the newly produced shoe tongue to be in a state of two layers adhered together. When ironing the label of the shoe tongue, it is necessary to turn over the shoe tongue manually after completing the ironing of one side, and then iron the label on the other side. The automatic shoe tongue label device of the prior art can only realize single-sided labeling of the shoe tongue. For the above-mentioned situation of two pieces of shoe tongue adhered together, double-sided ironing of the label is required. Generally, one side of the label is ironed first, and then the other side of the label is ironed after being collected and arranged, which requires a large amount of manual labor, because the shoe tongue needs to be rearranged and then supplied to the label device again, which is a great workload for manual work and has low production efficiency.

Either of the first labeling machine 61 and the second labeling machine 62 comprises a fixed frame 11, a conveying machine 12, a visual recognition unit 13, a label picking and placing unit 14, a label supply machine 15, an adhesive machine 16, and an electric control unit 17. The fixed frame 11 is a square frame body, which is used to support most of the parts of the first labeling machine 61 or the second labeling machine 62, and is placed on the surface of the platform and fixed; the conveying machine 12 is arranged on the fixed frame 11 and passes through the fixed frame 11, and is used to convey the tongue, which can be supported by the fixed frame 11 or by an independent support assembly; the visual recognition unit 13 is configured to collect the image of the tongue and determine the position of the tongue and the position to be labeled on the tongue, and is arranged above the conveying machine 12 and has a gap between the conveying machine 12, so that the tongue placed on the conveying machine 12 can pass through the gap to be imaged. The visual recognition unit 13 comprises a square dark box, in which a light source and a camera are arranged, the camera is used to collect the image of the tongue passing below the visual recognition unit 13, and the collected image is sent to a computer for processing and recognition. The label picking and placing unit 14 is configured to obtain the label from the label supply machine 15 and place the label on the position to be labeled on the tongue. The specific structure of the visual recognition unit 13 and the label picking and placing unit 14 can refer to Chinese patent application CN202321332776.4.

[0049] The label supply machine 15 is used to supply labels, and is arranged beside the conveying machine 12. The label supply machine 15 is usually a label printer, which can print the required labels in time and quickly, and automatically supply the printed labels to the label output part for taking away. The adhesive machine 16, also known as a label ironing machine or ironing machine, is arranged downstream of the label picking and placing unit 14. The adhesive machine 16 is used to fix the label on the tongue. The tongue on the conveying machine 12 carrying the label directly enters the adhesive machine 16, and the label ironing operation is completed in the adhesive machine 16, and then the tongue is collected.

[0050] In particular, the first labeling machine 61 has a tongue taking and placing unit 18 and a tongue supplying unit 19, while the second labeling machine 62 does not have a tongue taking and placing unit 18 and a tongue supplying unit 19. The function of the tongue taking and placing unit 18 is that it can regularly place the tongue on the conveyor, so that the tongue is kept in the same orientation, and the tongue is no longer disordered, so that when the label picking and placing unit picks and places the label, it no longer needs to be moved and rotated greatly to match the position and angle of the tongue. The function of the tongue supplying unit 19 is that it can regularly store and supply the tongue, that is, the tongue can be stored in the same orientation, so that when the tongue taking and placing unit obtains the tongue from the tongue supplying unit and places the tongue on the conveyor, the tongue is kept in the same orientation, and the tongue is no longer disordered. For specific description of the tongue taking and placing unit 18 and the tongue supplying unit 19, please refer to Chinese patent applications CN202421568370.0 and CN202421570440.6.
