Equipment for defect detecting and defect rejecting of hollow capsule

Abstract

The invention discloses equipment for defect detecting and defect rejecting of hollow capsules. The equipment comprises a stand and an automatic hollow capsule defect selecting device, wherein the stand is provided with a charging device and feeding device; the feeding device comprises a material storage bin, a feeding rotating disc, a capsule tray and a driving mechanism; the capsule tray is used for supporting the feeding rotating disc; the feeding rotating disc is provided with at least one circle of hole sites; the material storage bin is internally provided with a sweeping mechanism, and the material storage bin is separated into a sweeping area and a material stacking area; the material stacking area is internally provided with a baffle wall; a material storagea bin area positioned at the outer side of the baffle wall is a conveying area; the capsule tray which corresponds to the conveying area is provided with a discharge port from which the hollow capsules can drop from the hole sites; an outlet of the charging device is positioned above the material stacking area; the automatic hollow capsule defect selecting device comprises an industrial computer, a control circuit board, a high-speed industrial camera, an optical fiber amplifier, an encoder and a rejecting device used for rejecting defective capsules; a rotating shaft of the feeding rotating disc is provided with a triggering fluted disc; the encoder is arranged on the rotating shaft of the feeding rotating disc.

Description

technical field [0001] The invention relates to a hollow capsule detection device, in particular to a hollow capsule defect detection and defect elimination device with a cloth conveying function. 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, with an annual output of more than 100 billion gelatin hollow capsules, accounting for 30% of the world's hollow capsule market, and maintaining double-digit growth every year. [0003] In the prior art pharmaceutical hollow capsule production line, when the capsule body and capsule cap are closed, the capsule is sent out by a conveyor belt. The conveyor belt device has a complex structure, a large floor space, and high inve...

AI Technical Summary

Problems solved by technology

[0003] In the existing production line of medicinal hollow capsules, when the capsule body and capsule cap are closed, they are sent out by a conveyor belt. The structure of the conveyor belt device is relatively complicated, the floor area is large, and the investment cost is also high.

And because the hollow capsule production line will inevitably produce mechanical failures during the production process, the produced hollow capsules will inevitably have defects and waste products. The defects of the hollow capsules are mainly black spots and air bubbles on the surface, accounting for about 20% of the total. It varies from 1% to 3%, and the capsule waste must be separated from the genuine product before delivery to the pharmaceutical factory

If the conveyor belt device is irregular in the fabric of the hollow capsules, it will make it difficult to select the defects of the hollow capsules, and it is difficult to completely eliminate defective waste products

[0004] In addition, the existing empty capsule defect removal is done manually, but the manual detection efficiency is low and the stability is poor, which will also lead to incomplete rejection of empty capsules

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 rejected, etc., which lead to a great decline in the performance of the automatic evaluation machine, and cannot play the role of replacing manual labor
