Problems solved by technology

However, due to the unreasonable structure of the illuminant in the optical imaging system of this equipment, shadows, reflections, and uneven surface light appear on the capsule, and the image data obtained by taking pictures is distorted. However, it was not fully detected. The separation device used compressed air to blow out the defective capsules. The direction and landing point were not well controlled. The capsules often fell on the conveyor belt and mixed with the intact capsules. The removal of defective capsules was not thorough.
The device also cannot be used for the detection of capsule preparations that have been filled with drugs

Embodiment Construction

[0016] An embodiment of the present invention see figure 1 , the capsule inspection machine includes a positioning arrangement device 1 , a conveying device 2 , an image detection device 3 and a rejecting device 4 .

[0017] The positioning and arranging device 1 can be used in the hollow hard capsule production equipment or the positioning and arranging device in the hard capsule preparation filling equipment in the prior art. The positioning and arranging device 1 is installed at the front end of the conveying device 2 , and the positioning and arranging device 1 positions and arranges the capsules or capsule preparations, and transports them neatly and one by one to the through hole of the detection template 21 of the conveying device 2 .

[0018] see figure 2 and image 3 , the conveying device 2 includes a conveying belt 22 linked by detection templates 21, and the conveying belt 22 circulates on transmission wheels 23 and 24. Each detection template 21 may have one o...

Abstract

The invention discloses a capsule detecting machine which comprises a capsule arranging device, a transmitting device, an image detecting device and an eliminating device, an arch-shaped lampshade and a reinforcing light source are used for providing a light source which is uniform and has no shade on the surface of a capsule and leading the capsule to roll in the detection position, thereby being capable of shooting a complete capsule image, greatly reducing the distortion rate, improving the detection precision and leading the lost or wrong judgment rate to be low; and the eliminating device adopts an electromagnet and a push rod to greatly improve the capsule elimination rate and the precision. The machine has a wide range of applications and is suitable for detecting the hollow hard capsule and detecting a capsule preparation after filling medicine.

Description

technical field [0001] The invention relates to capsule testing equipment, in particular to testing equipment for detecting capsule defects and eliminating defective capsules. Background technique [0002] At present, the products of hollow hard capsule manufacturers, as well as the capsule preparations filled with hollow hard capsules in pharmaceutical factories, are sorted by manual visual inspection for unqualified products, and the capsules are poured into the hopper and dispersed into the atomizer with backlight. On the glass table, inspectors use naked eyes to check the capsules on the backlit table by hand to pick out defective capsules. This working method has low detection efficiency, high cost, and high labor intensity. The inspectors stare at the light for a long time with their naked eyes. Eye fatigue has a great impact on the inspection results, and it is easy to cause missed inspections, and the detection rate of defective products is low. Unstable quality, di...
