Pull piece sorting and feeding device

Abstract

The invention provides a pull piece sorting and feeding device. The pull piece sorting and feeding device comprises a vision recognition assembly, a straightening assembly and a face overturning assembly. The straightening assembly and the face overturning assembly are in linkage with each other. The straightening assembly comprises a work platform and a straightening mechanical arm located above the work platform. The face overturning assembly comprises a drive plate mechanism, a first discharging mechanism, a second discharging mechanism and a discharging track, wherein the first discharging mechanism and the second discharging mechanism are matched with the drive plate mechanism, and the discharging track is located below the first discharging mechanism and the second discharging mechanism. The vision recognition assembly comprises a first camera located above the work platform and a second camera located above the face overturning assembly. Through cooperation of the straightening assembly, the face overturning assembly and the vision recognition assembly, the orientation, the front face and the back face of a pull piece can be rapidly recognized, corresponding straightening or face overturning actions can be conducted, the pull piece sorting and feeding device is applicable to conventional pull piece sorting and feeding, meanwhile, sorting and feeding of special-shaped pull pieces or pull pieces with patterns can be achieved, and the application range is relatively wide.

Description

technical field [0001] The invention relates to a sorting device, in particular to a tab sorting and feeding device. Background technique [0002] Zipper is an important accessory material, which is widely used in all kinds of bags, shoes and clothing products. The slider is an important part of the zipper, which is mainly assembled from parts such as the body, the cap and the pull piece. [0003] The slider is usually assembled by the automatic slider assembly machine, which needs to put the pull tabs with the same orientation and the same front and back into the automatic slider assembly machine, that is, the pull tabs need to be sorted and sent to the automatic slider assembly machine middle. At present, most enterprises use vibrating discs to realize the sorting and feeding of pull tabs, such as the pull tab sorting transmission device and slider assembly equipment disclosed in the Chinese invention patent application with the publication number CN106583255A. The vibra...

Problems solved by technology

However, this type of sorting and feeding device can only realize the sorting and feeding of pull tabs with conventional structures. For some special-shaped pull tabs, it is easy to overlap or jam. For some front and back structures that are symmetrical to each other but the front and back Pull tabs with different patterns, it is difficult for this type of device to correctly distinguish the front and back sides, all of which need to be processed manually, and the scope of application is relatively small
