Sorting apparatus for down feather

Abstract

The invention discloses a sorting apparatus for down feather, which has high sorting efficiency and high sorting precision. The sorting apparatus comprises a down feather conveying belt, which is driven by a main conveying roller and a driven conveying roller, and the down feather for sorting are spread on the down feather conveying belt. In the conveying direction of the down feather conveying belt, an image collecting device and a down feather sorting device are successively arranged above the down feather conveying belt. The image collecting device uses a camera to continuously collect images of the down feather on the down feather conveying belt. The down feather sorting device includes a plurality of down feather sucking parts, each of which is connected to a control device. The down feather sucking parts are faced to the down feather conveying belt. Any one position on the down feather conveying belt, when moving to under the down feather sorting device, is corresponding to one down feather sucking part. According to the image information collected by the image collecting device, when down feather requiring to be sorted exists in one position on the down feather conveying belt, the down feather sucking part that is corresponding to the position on the down feather conveying belt sucks up the down feather requiring to be sorted.

Description

technical field [0001] The invention relates to a sorting device, in particular to a down sorting device, which is used for sorting and removing impurity down mixed together Background technique [0002] Down is widely used in modern home furnishing and clothing production, and the presence of impurities (such as variegated down) in down is inevitable. Even after careful picking and sorting, down cannot be free of impurities. At present, down processing enterprises basically rely on manual visual observation and use manual picking to remove impurities in down. This method is tedious, inefficient, and prone to missed inspections. [0003] In order to solve the above problems, the patent document with the application publication number CN105855189A discloses an intelligent high-speed down color sorter, the color sorter includes a down conveyor belt, and the down conveyor belt is divided into an upper down section, a detection section, and a sorting section in turn. There is ...

AI Technical Summary

Problems solved by technology

[0004] (1) With the DELTA robot, the DELTA robot needs to move to the sorting position, and its sorting speed is greatly affected. Although the efficiency is higher than that of manual sorting, it still cannot meet the actual high-speed requirements

[0005] (2) The DELTA robot uses single-point sorting down, and it needs to sort the defective down multiple times in sequence, which is inefficient

[0006] (3) The detection lens array is used, that is, multiple lenses are used, and the cost is relatively high

[0007] (4) The detection lens array adopts static interval scanning (collecting images), which is inefficient

[0008] (5) The detection lens array is used. Since each camera has a field of view per unit area, when processing a unit area, the down with good quality in the unit area is also selected, and the loss is large, resulting in the loss of good-quality down materials. waste

[0009] (6) Using the detection lens array, when the defective down is at the edge between the detection lenses, it will be captured by two or more detection lenses, causing the down in multiple fields of view to be judged as unqualified, resulting in multiple Good quality down within a unit area is also selected, and the loss is large

Similarly, with the detection lens array, when the defective down is at the edge between the current detection lens and the next detection lens, it will be captured by the current and next detection lens, causing If the down is judged as unqualified, it will result in the selection of good quality down in multiple unit areas, resulting in a large loss and waste of good quality down materials.

[0010] (7) Use a micro-frequency conversion fan to form a negative pressure on the down conveyor belt so that the down is evenly adsorbed on the down conveyor belt, and the loss is large

[0011] (8) Start and stop the conveyor belt at intervals, and the error of the conveyor belt position cannot be avoided due to the start and stop, so that the images collected by the detection lens array at intervals overlap and have intervals, increasing the error of sorting
