Description

Technical field:

[0001] The utility model relates to a filling bottle detection device for preparing Chinese patent medicines. Background technology:

[0002] In the preparation process of Chinese patent medicine, a rotary negative pressure filling machine and a capping machine are usually used for filling operations. The liquid bottles are transported to the bottle feed wheel through the mesh belt conveyor mechanism, and the bottle feed wheel transfers the liquid bottles to the negative pressure filling machine for negative pressure filling; after the filling is completed, the negative pressure filling machine transfers the liquid bottles to the capping machine for capping, and finally the liquid bottles output by the capping machine are transferred by the bottle output wheel to another mesh belt conveyor mechanism for output.

[0003] However, before filling the liquid bottles with Chinese patent medicines, they need to be dried in an oven at 140 degrees. During the drying process, the bottles may explode, and some of them may drop small pieces of glass. However, due to the high production speed (up to 300 bottles / minute), it is impossible to manually detect the liquid bottles with small pieces of glass in them. Therefore, it is necessary to improve the above technical problems so as to detect the liquid bottles with small pieces of glass in them before filling, and this case is born. Utility model content:

[0004] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a filling bottle detection device for preparing Chinese patent medicine.

The bottle feeding dial wheel transfers the liquid bottle to the negative pressure filling machine, the negative pressure filling machine negatively pressure fills the Chinese patent medicine into the liquid bottle, then the capping machine caps the liquid bottle, and the capped liquid bottle is transferred to the bottle discharging dial wheel, which outputs the liquid bottle; further, an inspection station 5 is arranged at the front end of the bottle feeding dial wheel 1, and the inspection station 5 is provided with a camera 6 which is located above the bottle feeding dial wheel 1 and is electrically connected to the control unit, and the camera 6 detects the bottle feeding dial wheel from top to bottom. 1 is transported to the liquid-filling bottle 7 directly below the camera 6 for photographing, and the control unit compares the picture taken by the camera with the preset transparent liquid-filling bottle picture to determine whether the picture taken by the camera produces a bright spot. If the photographed picture produces a bright spot, it proves that there are small glass fragments in the liquid-filling bottle; the front end of the bottle-discharging dial wheel 4 is provided with a marking station 8, and the marking station 8 is provided with a marking mechanism. The marking mechanism is used to set a mark on the liquid-filling bottle with a bright spot in the picture after being photographed by the camera, so as to mark the liquid-filling bottle with small glass fragments, so as to facilitate manual inspection and rejection of the marked liquid-filling bottle after the subsequent bottle-discharging dial wheel outputs the liquid-filling bottle.

[0021] In this embodiment, the detection station 5 is provided with a light source 9 for emitting white light upwards below the bottle feeding dial wheel 1, and the light source 9 is directly opposite to the position of the camera 6. By providing a light source emitting white light, it is convenient to supplement the camera's photography.

[0022] In this embodiment, the camera 6 is a high-speed wide-angle camera.

[0023] In this embodiment, the marking mechanism includes a paint spray head 10 disposed above the bottle discharge dial wheel 4, and the paint spray head 10 is used to spray paint toward the bottle cap of the liquid bottle 7. Further, the paint spray head is connected to the paint storage tank through a pipeline, and the pipeline is provided with a delivery pump for delivering the paint in the paint storage tank to the paint spray head.

[0024] In this embodiment, the detection station 5 is also provided with a photoelectric switch 11 located in front of the bottle feed wheel.

[0026] In this embodiment, there is a transfer wheel (not shown) between the negative pressure filling machine and the capping machine, which plays a role of transfer transition. The bottle feeding wheel rotates counterclockwise, the filling wheel of the negative pressure filling machine rotates clockwise, the transfer wheel rotates counterclockwise, the capping machine rotates clockwise, and the bottle discharging wheel rotates counterclockwise, and the five rotate synchronously. In order to count, the rotating shafts of the bottle feeding wheel, the filling wheel of the negative pressure filling machine, the transfer wheel, the capping machine, and the bottle discharging wheel are all equipped with synchronous encoders 14. The specific principle is: the bottle inlet dial wheel will detect the liquid bottle with small glass fragments inside at the detection station and rotate it counterclockwise 120 degrees to reach the filling dial wheel of the negative pressure filling machine. The filling dial wheel of the negative pressure filling machine will rotate the liquid bottle clockwise 270 degrees and reach the transfer dial wheel. The transfer dial wheel will rotate the liquid bottle 270 degrees and reach the capping machine. The capping machine will rotate the liquid bottle 270 degrees and reach the bottle outlet dial wheel. The bottle outlet dial wheel will rotate the liquid bottle counterclockwise 120 degrees to reach the standard station.
