JKZ400/25 vial lyophilizer automatic inspection machine

Main Use

This machine is suitable for detecting visible foreign objects and appearance defects in lyophilized injections of molded or controlled vials in pharmaceutical factories.

Working Principle

The equipment is divided into the following main parts: bottle feeding mechanism, transition wheel mechanism, turntable detection mechanism, camera light source tracking mechanism, bottle output wheel separation mechanism, servo motor control mechanism, body and protective cover mechanism, etc.

When the inspected medicine enters the conveyor belt, it is sent to the bottle feeding wheel by the horizontal conveyor belt. The bottle feeding wheel separates the medicine at equal distances and then continuously sends it to the corresponding rotating bottle seat in the turntable detection area. The pressing head corresponding to the rotating bottle seat presses the inspected medicine to ensure that the pressing head, the inspected medicine, and the rotating bottle seat form an independent detection unit. The inspected medicine, the pressing head, and the rotating bottle seat rotate uniformly with the turntable. After entering the detection area, the inspected medicine rotates more than one revolution, and the high-speed camera takes pictures of the inspected medicine. There are a total of six detection stations: cap defect detection station, bottle bottom defect and medicine visible defect detection station, and four bottle body and medicine defect detection stations. If any defect exists in the inspected item, it can be judged after comparing multiple frames of images. When the inspected medicine is sent to the bottle output wheel, the corresponding pressing head releases the inspected medicine through a cam device, and the inspected medicine enters the bottle output wheel. The qualified and unqualified products are separated by the rejection device.

Inspection Items

Includes product defect detection, container appearance defect detection, and sealing defect detection, the main inspection items are as follows:

1. Cap part: Whether the aluminum cap composite cap is complete, whether the crimping part is uniform and beautiful (such as crimping crooked, burrs, wrinkles, etc.)

2. Check the bottle neck for stoppers;

3. Whether there are lyophilized spots formed by splashing of medicine in the transparent part of the upper part of the bottle;

4. Whether the lyophilization in the lower part of the bottle body, that is, the lyophilized medicine part, is uniform, whether there are missing parts of lyophilization, and whether there are visible foreign objects on the surface of the lyophilization;

5. Whether the lyophilization at the bottom of the bottle is uniform and complete, and whether there are visible foreign objects on the surface of the lyophilization;

6. Whether there are visible foreign objects in the lyophilized medicine part in the bottle;

7. Whether there are cracks in the visible parts of the bottle body and bottom;

8. Overfilling, underfilling, empty bottles;

Main Technical Features

1. The detection accuracy is adjustable, suitable for different detection requirements of different items.

2. The patented technology (see "Patent Technology" in "Manufacturing and Quality" on the company website) designed transmission device ensures that the detected object is transmitted smoothly and smoothly.

3. Servo motors are used in multiple parts instead of traditional mechanical transmission, and the control and detection procedures are completely connected, improving the accuracy requirements of the inspected items.

4. The standard parts adopt a quick-positioning pin design, which makes the replacement and adjustment of standard parts simple and convenient.

5. Imported industrial cameras with 50x magnification and high resolution are used. Because the light is directly applied to the detected object, the visibility of the detected defects is stronger, and the detection accuracy and effect are better than manual detection.

6. Up to six work stations can detect all defects.

7. Key components of the equipment are processed by precision CNC machine tools to ensure the accuracy and quality of the components.

8. The overall appearance of the machine is beautiful and generous, and the machine body panel, bottom plate and other parts are treated with special protective spraying.
