Technical Field

The invention belongs to the technical field of medicine detection, and particularly relates to a medicine powder neglected loading detection and rejection system based on visual identification.

Background

With the rapid development of the pharmaceutical industry, the dependence on automation, both in terms of product quality and production efficiency, is increasing. At present, no humanization is basically realized from the production of medicinal powder to the packaging of finished products, but in the working procedure of bottling the medicinal powder, the phenomena of more medicinal powder, less medicinal powder and neglected medicinal powder packaging exist in the medicament charging equipment produced at home or abroad.

Once defective products with more, less and neglected packages of the medicine powder appear, the defective products directly flow into hospitals or patients, and the reputation of pharmaceutical enterprises is seriously damaged. Under the circumstances that the powder charge equipment can not guarantee the hundred per cent to every bottle capacity powder charge, can only rely on the later stage to realize the zero outflow of defective products through the mode that detects the rejects.

Because the transportation speed when the medicine bottle detects is very fast, take the detection line of visual inspection as an example, the speed that the medicine bottle passes through the detection position is 10 bottles/second usually to be closely adjacent between the medicine bottle, even can discern the defective products with prior art, also be difficult to carry out effectual pursuit and rejection to the defective products.

Therefore, in the prior art, after detection is completed, defective products need to be screened for the second time, medicines with leaked medicine powder are screened out, and the method is low in efficiency, time-consuming and labor-consuming.

Disclosure of Invention

The invention provides a medicine powder neglected loading detection and removal system based on visual identification, aiming at the problems that in the prior art, defective products need to be screened for the second time and are time-consuming and labor-consuming.

The basic scheme provided by the invention is as follows:

the visual recognition-based medicine powder neglected loading detection and elimination system comprises a conveying belt for conveying medicines, wherein a photographing position and an elimination position are arranged on the conveying belt; further comprising:

the identification unit is used for collecting image data and is positioned at a photographing position of the conveyor belt;

the rejecting unit is used for rejecting the medicine bottles and is positioned at a rejecting position of the conveying belt;

the processing unit is used for analyzing and judging the acquired image data;

the positioning unit comprises N sensors which are sequentially arranged along the conveying direction of the conveying belt, the distance between any two adjacent sensors is smaller than the diameter of the cross section of the medicine bottle body, the first sensor is positioned at the photographing position, and the distance between the Nth sensor and the removing position is smaller than the diameter of the cross section of the medicine bottle body; the numerical value of N is not less than three; the N sensors are positioned on the same side of the eliminating unit;

the processing unit controls the identification unit to collect image data after receiving a detection signal of the first sensor; if the analysis and judgment result of the processing unit is abnormal and the detection signals from the first sensor to the Nth sensor are sequentially and continuously received, the processing unit sends a rejection signal to the rejection unit; the rejecting unit rejects the medicine bottle after receiving the rejecting signal.

Basic scheme theory of operation and beneficial effect:

when detecting the medicine bottle, the medicine bottle can loop through N sensilla and the position of rejecting unit when passing through the assembly line.

When the medicine bottle passed through first sensor, the medicine bottle arrived the position of shooing, and processing unit is given with detected signal transmission to processing unit control recognition unit gathers the image data of this medicine bottle to carry out analysis and judgement to image data. The vial continues to advance past the second subsequent sensor, which in turn sends a detection signal to the processing unit.

Because the distance between the adjacent sensors is smaller than the diameter of the cross section of the bottle body of the medicine bottle, when the latter sensor just detects a certain medicine bottle, the former sensor is still in the state of detecting the medicine bottle. Thus, the detection signals sequentially sent by the N sensors can be ensured to be the detection signals of the same medicine bottle, and when the defective product is detected, the position of the defective product can be continuously tracked according to the feedback signals of the sensors. Simultaneously, set up N sensor, the medicine bottle loops through the process of N sensor, can provide sufficient operating time for the processing unit and carry out the abnormal analysis of medicine bottle and detect. Because the distance from the Nth sensor to the rejecting position is smaller than the diameter of the cross section of the bottle body of the medicine bottle, the processor already starts to enter the rejecting position after receiving the detection signal sent by the Nth sensor, namely the medicine bottle leaves the Nth sensor.

If the analysis and judgment result of the processing unit indicates that the medicine bottle is abnormal (such as more medicine powder, less medicine powder, neglected medicine powder and the like) and the detection signals of the N sensors are sequentially and continuously received, the medicine bottle is indicated to be unqualified and continuously passes through the positions of the N sensors and is positioned at the position of the rejecting unit, therefore, the processing unit sends rejecting signals to the rejecting unit, and the rejecting unit rejects the defective products.

By using the system, the medicine bottles can be continuously photographed, analyzed and rejected. Compared with the prior art, can be under the condition that does not influence normal medicine bottle, accurate discern the defective products and reject out, need not carry out the secondary screening after detecting out the defective products, very big improvement the whole efficiency that the medicine bottle defective products detected, and whole process is full automatic, saves time and saves worry laborsaving.

In addition, all defective products can be eliminated by the aid of the eliminating mode, zero output of the defective products is guaranteed, and compared with manual screening, the eliminating rate of the defective products is guaranteed.

Furthermore, the rejection unit comprises a servo motor and rotating fan blades, and the centers of the rotating fan blades are fixed with a rotating shaft of the servo motor; and the processing unit controls the servo motor to rotate by a preset angle after the analysis and judgment result shows that the abnormality exists and the detection signals from the first sensor to the Nth sensor are sequentially and continuously received.
