Novel color sorter

Abstract

The invention relates to a color sorter, in particular to a color sorter with a novel blanking system. The structural scheme shown in the drawing 2 is adopted. The blanking system of the novel color sorter comprises a vibrator (1), a vibration hopper (2), a slideway (3), a CCD (Charge Coupled Device) (4) and a spray valve (5). Materials are vibrated by the vibrator to be flatly laid on the hopper, and slide down along the slideway, and after material images acquired by the CCD are identified by the color sorter system, unqualified materials are separated by the spray valve (5). According to the novel color sorter, the materials are vibrated by the vibrator to be flatly laid on the vibration hopper, and can not roll in the sliding process, the speed of the materials at the outlet of the slidway approximates to the speed of the materials at the outlet of the hopper, and the delay control between the material pick-up of the CCD and the action of the spray valve is not needed. The better material image acquisition effect and higher color sorting precision are realized. The impact of the blanking system of the traditional color sorter on the image acquisition effect is avoided, and the color sorting precision is improved.

Description

technical field [0001] The invention relates to a color sorter, in particular to a color sorter with a novel blanking system. Background technique [0002] Traditional color sorter structure such as figure 1 As shown, it includes a vibrator (1), a vibrating hopper (2), a slideway (3), a CCD (4), a spray valve (5), and a feeding hopper (7). The material falls evenly into the vibrating hopper (2) through the feeding hopper (7), the vibrator (1) spreads the material on the vibrating hopper (2), slides down through the slideway (3), and the CCD collects the picture of the material through color sorting After identification by the machine system, unqualified materials are separated by the spray valve (5). The slideway is basically at about 60 degrees, and the length of the slideway is about 1 meter. The thin plastic plate or other soft material that needs to be covered on the slideway ensures that the material slides down in a certain direction and angle. The material slides do...

Problems solved by technology

[0003] Due to the large structure of the existing color sorter, the falling speed of the material in the material feeding system is inconsistent, and the material is tumbling, which seriously affects the image collection effect, especially for flat materials (such as watermelon seeds), and there is a gap between the spray valve and the CCD. Large gaps, processing delays and other issues have a great impact on the image acquisition effect of materials
