Automatic selection and elimination device for hollow capsule defect

Abstract

The invention discloses an automatic selection and elimination device for a hollow capsule defect. The device comprises a rotary disc type hollow capsule feeding device and a hollow capsule selection device, wherein the rotary disc type hollow capsule feeding device comprises a feeding rotary disc; the feeding rotary disc is provided with holes for placing hollow capsules; a rotating shaft of the feeding rotary disc is provided with a trigger tooth disc; the hollow capsule selection device comprises an industrial controller, a control circuit board, a high-speed industrial camera, an optical fiber amplifier, an encoder, an elimination device and a collection box; the control circuit board is connected with the industrial controller; the high-speed industrial camera is connected with the control circuit board; the optical amplifier is arranged corresponding to the trigger tooth disc and is electrically connected with the control circuit board; the encoder, the elimination device and the collection box are electrically connected with the control circuit board; the encoder is arranged on a rotary disc of the feeding rotary disc; the high-speed industrial camera is correspondingly arranged above the feeding rotary disc and acquires image information of hollow capsules; the industrial controller is used for receiving the image information from the high-speed industrial camera and positional information from the optical amplifier and the encoder and emits a control instruction to the elimination device.

Description

technical field [0001] The invention belongs to the technical field of automatic detection of product quality of hollow capsules, and in particular relates to a device for automatically selecting and eliminating defects of hollow capsules. Background technique [0002] In recent years, with the rapid development of the pharmaceutical industry, China's pharmaceutical output value has exceeded one trillion yuan, of which my country's pharmaceutical capsules have accounted for 20% of the total pharmaceutical preparations. By the end of 2010, there were more than 3,000 approved capsule manufacturers, and the annual output of gelatin hollow capsules was more than 100 billion, accounting for 30% of the world's hollow capsule market, maintaining double-digit growth every year. The State Food and Drug Administration requires that manufacturers of medicinal gelatin, medicinal capsules and capsules must be equipped with inspection equipment and inspection personnel suitable for the pr...

Problems solved by technology

[0004] At present, the single-row hollow capsule hole chain plate automatic inspection machine that appears on the market has a maximum speed of about 7 capsules per hour, which is far from meeting the inspection speed required by a single production line. Problems such as position jitter, qualified capsules being mistakenly picked, unqualified capsules missed or failed to be picked out, etc., lead to a significant decline in the performance of the automatic evaluation machine, which cannot replace manual work
