Sorting machine for capsules

Abstract

The invention discloses a sorting machine for capsules. The sorting machine comprises a rack and motors. The rack is provided with a shooting device and further provided with an image analysis system used for analyzing images shot by the shooting device. Feeding systems, end face shooting systems and circumferential face shooting systems are arranged on the rack. The feeding systems comprise storage wheels. A first feeding wheel and a first adsorption wheel are arranged on the other side of each storage wheel, and the end faces of the first feeding wheels are attached to the end faces of the first adsorption wheels. A plurality of first arc-shaped grooves are formed in the outer circumference of each first feeding wheel. The end face shooting systems comprise second feeding wheels, and a plurality of second arc-shaped grooves are formed in the outer circumference of each second feeding wheel. End face cameras connected with the image analysis system are further included. The circumferential face shooting systems comprise inner barrels and outer barrels, and the inner barrels and the outer barrels can move and have a speed difference. The speed difference of the linear speed of the inner barrels and the outer barrels can be controlled by controlling the rotating speed of the inner barrels and the outer barrels, namely, the rolling length of the capsules; and the rotating speed of the outer barrels can be further increased, and it can be guaranteed that the treatment efficiency of the machine is greatly improved.

Description

technical field

[0001] The invention belongs to the field of capsule machinery, in particular to a capsule sorting machine. Background technique

[0002] In the production of capsules, there will inevitably be some defective products, such as cracks, burrs, bubbles, spots, etc. These defective products need to be sorted out before leaving the factory. The basis for identifying defective products is mainly their optical properties, and these defects can be seen from their appearance. Therefore, in the early days, sorting was carried out by means of manual identification. For example, Chinese patent 200920299531X discloses a sorting table for capsules, which actually manually detects unqualified products under the illumination of a light source. With the development of image recognition technology, computer recognition and sorting has become the mainstream in recent years. For example, Chinese patent application 2014101405772 discloses a fully automatic optical capsule defect...
