[0002] The capsule defect detection machine mainly includes a feeding unit, a conveying unit, a rotating capsule unit, a detection unit, a rejection unit, and a discharging unit. The capsules are neatly arranged and transported to the roller of the conveying unit through the feeding unit, and then transmitted to the rotating capsule unit through the conveying unit. The rotating capsule unit rotates the capsules to ensure that the various detection devices of the detection unit perform 360-degree all-round detection on the capsules. After the detection is completed, the capsules will be transmitted to the rejection unit through the conveying unit. After the defective products are rejected by the rejection unit, the good capsules on the conveying unit will be transmitted from the conveying unit to the capsule collection area through the discharging unit. At present, the discharging unit adopts an automatic blowing device to blow air on the capsules on the conveying unit to make them leave the conveying unit. However, the use of blowing to discharge the material is likely to cause the capsules to fly around and collide during the blowing process, causing the capsules to split, resulting in secondary defects, especially for filled capsules. In addition, the capsule powder caused by secondary damage will remain on the machine, affecting the capsules. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the above-mentioned blowing method of discharging, and to provide a new discharging structure to ensure that the capsule will not cause secondary damage when discharging.

[0018] The above technical solution is now explained with reference to examples shown in the figure.

[0019] The capsule defect detection device of the present invention is shown in FIG. Figure 1 , including equipment frame A, fixed panel B, feeding unit C, conveying unit D, rotating capsule unit E, detecting unit F, rejecting unit G, discharging unit H, screening unit I, and electric control unit J. Panel B is installed on the equipment frame A. The capsule feeding mechanism is fixed on panel B. The capsules are vibrated into the cavities of two sets of rotating feeding trays by the vibration module on the feeding module, and are arranged in order on the rollers of the conveying unit. The rollers are driven to the detection unit through the main transmission chain for visual inspection. The capsules are evenly arranged by the equal division of the unloading wheel. The capsules are rotated while the capsules are translated. The capsules are inspected online, at high speed, and one by one, and unqualified products are automatically rejected. At the same time, the end scanning camera is used for imaging to perform 360° appearance inspection of the capsules and full-automatic inspection of the internal inspection of the capsules. The capsules are judged by the visual software to calculate the good and bad products. The conveying unit moves to the rejection unit and is automatically rejected to the bad product area. The good products are orderly arranged to the screening unit through the discharging unit for secondary identification. The working state is stable, the performance is reliable and durable, the detection accuracy is high, the cost is low, and the quality of the capsule rear packaging is effectively improved. It can be incorporated into the fully automatic capsule production line, which can meet the detection of capsules of different models, and is easy to clean and clean. It can discharge evenly and stably to ensure the quality of the capsules.

[0020] The discharging unit H is composed of a power transmission, a rotating axis 12, a base fixing seat 1, a negative pressure module including a negative pressure source block 4, an axis 2, a linear bearing 3, and a spring; a rotating turntable 15, an automatic telescopic module including a slider 13, a connecting shaft 14, a customized suction nozzle 7, a cam 5, a movable limit plate 9, and a turntable fixing ring 8.

[0021] The base fixing seat 1 is fixedly mounted on the mounting panel B through the bearing seat. The rotating axis 12 is fixedly connected to the rotating turntable 15 through the bearing of the bearing seat 11 to drive the rotating turntable to rotate. A circular limit plate 9 is fixedly arranged on the rotating turntable, and a circle of long limit through-hole grooves arranged at intervals are provided on the limit plate 9 along its circumference. The automatic telescopic module includes a slider 13, on which a connecting shaft 14 is fixedly arranged; the suction nozzle 7 is fixedly arranged at the end of the connecting shaft and extends out of the edge of the movable limit plate; a protrusion is arranged on the slider 13, and the protrusion on the slider is arranged in the limit through-hole groove 16, so as to ensure that the slider can make reciprocating linear displacement along the limit through-hole groove to prevent the slider from shaking left and right. The slider is connected to the rotating turntable through a spring 17. A cam 5 is fixedly arranged on the fixed mounting seat outside the slider. When the slider rotates to the cam 5 along with the rotating turntable, the cam 5 presses the fixed bearing 10 on the slider to retract along the limiting through-hole groove toward the center of the rotating turntable. The slider drives the suction nozzle to retract toward the center of the circle, so that the suction nozzle is separated from the negative pressure source of the negative pressure module. When separated from the cam, the slider slides outward away from the center of the circle under the action of the spring, driving the suction nozzle to extend outward to the position of the prepared adsorption capsule. A hollow channel is provided on the connecting shaft 14, and the suction nozzle 7 is fixedly installed at one end of the connecting shaft 14. A suction nozzle connection port is provided on the connecting shaft to communicate with the hollow channel. The suction nozzle is elastically connected to the suction nozzle connection port on the connecting shaft through the negative pressure module to provide negative pressure adsorption force for the suction nozzle.

[0022] The negative pressure module includes a negative pressure source block 4 located between the base fixing seat 1 and the rotating turntable 15. The negative pressure output end of the negative pressure source block is an elastic elastic member. The negative pressure output end of the negative pressure source block can be in sealed contact with the suction nozzle connection port on the rotating turntable to provide negative pressure suction for the suction nozzle; a plurality of linear bearings 3 are fixedly installed on the base fixing seat 1 at intervals, the axis 2 is inserted through the linear bearing 3 and fixedly connected to the negative pressure source block 4, and the spring (not shown) is fixedly connected to the axis 2. Through the action of the linear bearing 3 and the spring, the negative pressure source block 4 can be linearly extended and retracted along the linear bearing 3 to ensure that the negative pressure source block is in sealed contact with the suction nozzle connection port on the rotating turntable.

[0023] When the rotating turntable drives the suction nozzle to rotate to the negative pressure source block area, the negative pressure source block and the suction nozzle contact port are sealed to provide negative pressure suction for the suction nozzle to perform capsule adsorption. The negative pressure source block 4 is located on the inner side of the cam 5. When the suction nozzle adsorbs the capsule and moves to the cam, the slider retracts toward the center of the circle under the action of the cam, driving the suction nozzle adsorbing the capsule to retract and detach from the negative pressure source block. The suction nozzle loses negative pressure suction, and the capsule on the suction nozzle falls into the feeding channel under a certain centrifugal force and enters the capsule collection area.

[0024] The discharging unit mechanism (H) is better sealed with the rotating turntable 15 through the movable negative pressure module, so as to obtain a better vacuum degree, realize the capsule lifting action, stably discharge the material, and ensure the quality of the capsule.
