Online detection device for oil impregnated soft capsule

Abstract

The invention discloses an online detection device for an oil impregnated soft capsule. The online detection device comprises a feeding module, a multi-waveband image acquiring and processing module, an oil impregnated capsule eliminating module and a system control module, wherein the feeding module comprises a vibration loading machine, a capsule guide pipe, a conveying chain and a capsule collection device; the multi-waveband image acquiring and processing module comprises a computer, an image acquiring camera, a light box and an illumination light source; the oil impregnated capsule eliminating module comprises a photoelectric induction sensor, a gas storage tank and a pneumatic nozzle; the system control module comprises a computer and a PLC (Programmable Logic Controller). According to the online detection device, a monochromatic camera is used for obtaining a capsule image under a light source with a plurality of wavebands through a light source design process and an image acquisition process; characteristic parameters of the image of the capsule under the light source with the plurality of wavebands are extracted and a relation model between the characteristic parameters of the image of the capsule and the oil impregnated capsule is established; whether the capsule is qualified or not is identified by the model; an online detection aim of the capsule is realized by high-speed image acquisition equipment and image processing software. The online detection device for the oil impregnated soft capsule can be applied to online rapid detection of the oil impregnated soft capsule.

Description

technical field [0001] The invention relates to an online detection device for the quality of soft capsules, in particular to a device for online detection of oil seepage soft capsules based on multi-band image technology. Background technique [0002] Soft capsules, also known as capsules, are a new dosage form developed after tablets, hard capsules, pills, injections, oral liquids, etc. The drug powder is quantitatively injected and encapsulated in the film to form sealed capsules of various sizes and shapes. Compared with other dosage forms, it has the characteristics of high bioavailability, accurate content, good uniformity, can cover the odor of the drug and other contents, beautiful appearance, and improve drug stability. It has the advantages of less impurities, more main components, high bioavailability, and fast absorption, and is very suitable for the packaging of medicines and health care products. [0003] During the production process of soft capsules, the ca...

Problems solved by technology

At the same time, the temperature of the soft capsule is too high during the production process, causing the film to be damaged during tablet compression, resulting in leakage of the contents; or the temperature is too low, resulting in poor adhesion between the two films, and holes in the joints of the soft capsule film , causing oil seepage

For the removal of oil pellets, manufacturers generally use manual inspection, which not only has high labor costs, but also is slow

There are some existing capsule detection devices, such as the related patent "Apparatus and method for on-line detection of soft capsule quality based on computer vision" (application number: CN200610096741.X) which describes the application of machine vision to detect the quality of soft capsules; Machine" (Application No.: CN201220101158.4) describes a detection device for transparent capsules, which has a limited application range, and the above two patents cannot effectively characterize the characteristics of oil-leaching capsules
