Description

Technical Field

[0001] The present invention relates to the technical field of drug testing equipment, and in particular to a full-automatic tablet testing equipment. Background Art

[0002] Currently, most oral medicines produced are in the form of tablets. The quality of tablets directly affects the quality of the entire medical product. Therefore, the production of tablets has strict requirements. Defective tablets that are broken, damaged, or have impurities on the surface during the production process need to be selected out.

[0003] There are hundreds of varieties of tablets, and their appearance, shape, and size vary greatly. If only manual selection is used, not only will the labor cost be high, but it will also be difficult to fully grasp the appearance, shape, and size of the tablets, which can easily lead to misdetection and missed detection, affecting the qualified rate of the tablets. Existing automatic inspection equipment still has certain problems in adapting to tablets of multiple sizes, keeping the inspection machine clean, and maintaining the belt. Summary of the invention

[0015] The third detection unit is used to detect the lower surface of the tablet;

[0016] The fourth detection unit is used to detect the outer surface of the tablet;

[0017] The second rejection module is used to reject unqualified tablets.

[0018] Furthermore, the belt conveyor device comprises a lifting mechanism, and the lifting mechanism is used to carry the second belt conveyor mechanism.

[0019] Furthermore, the first belt conveying mechanism and the second belt conveying mechanism include a tensioning mechanism;

[0020] The tensioning mechanism includes a tensioning cylinder and a tensioning wheel; the tensioning cylinder includes a slider, a guide rod and two end heads; the guide rod is arranged between the two end heads, the slider slides along the guide rod between the two end heads, and the tensioning wheel is fixed on the slider.

[0022] Furthermore, the first belt conveyor mechanism and the second belt conveyor mechanism each include an air suction groove and an air suction belt;

[0023] In the first belt conveyor mechanism, the suction groove is horizontally arranged at the lower side of the suction belt at the top of the first belt conveyor mechanism;

[0024] In the second belt conveyor mechanism, the suction groove is horizontally arranged on the upper side of the suction belt at the bottom of the second belt conveyor mechanism;

[0025] The air suction groove of the first belt conveyor mechanism does not extend to the tablet handover area; the air suction groove of the second belt conveyor mechanism extends to the tablet handover area.

[0030] The material sorting device functional module is arranged in the material sorting device and is communicated with the pipeline integration system, and is used for collecting tablet dust and debris in the material sorting device.

[0031] Beneficial effects of the present invention:

[0032] The present invention arranges tablets and conveys them to two groups of belt conveyor systems arranged at adjacent positions through a material sorting device. During the process of transporting the tablets to be inspected by the two groups of belt conveyor systems, the upper surface and the lower surface of the tablets are exposed respectively. One group of inspection devices performs image inspection on the upper surface and the inner side of the tablets respectively, and the other group of inspection devices performs image inspection on the lower surface and the outer side of the tablets respectively, thereby realizing comprehensive tablet image inspection.

[0033] The detection device of the present invention is also provided with two groups of reject modules, which are respectively arranged behind the two groups of detection devices, and the tablets that fail the detection are directly rejected after the tablets are detected.

[0034] In the present invention, the second belt conveyor mechanism is arranged on a height-adjustable lifting mechanism, so that the height of the gap between the first belt conveyor mechanism and the second belt conveyor mechanism in the adjacent area can be adjusted to meet the needs of conveying tablets of different heights.

[0035] The belt transport mechanism of the present invention drives the tensioning wheel through the tensioning cylinder to adjust the tension of the belt. When the belt becomes loose, deviates or slips, the tensioning force of the belt can be maintained by driving the tensioning wheel position by adjusting the cylinder, thereby solving the problems of the belt becoming loose, deviating or slipping. At the same time, when the detection system needs to disassemble the belt for maintenance, the position of the tensioning wheel is adjusted by the tensioning cylinder to facilitate the disassembly of the belt.

[0036] In the detection system of the present invention, a limiting collar is also provided on the tension cylinder guide rod. When the tension cylinder is loosened when the air is cut off, the belt will loosen, causing the belt to deviate or fall off easily when the machine is inflated and started next time if the belt is not installed in the specified position. Therefore, a collar is installed on the guide rod to limit the position. When the tension wheel position needs to be adjusted to disassemble the belt, the screws on the two collars need only be loosened.

[0037] In the present invention, the adjacent part between the first belt conveyor mechanism and the second belt conveyor mechanism is the tablet handover area. In the tablet handover area, the first belt conveyor mechanism is not provided with a suction groove, so that the tablets stay on the top of the first belt conveyor mechanism due to gravity; at the same time, the second belt conveyor mechanism is provided with a suction groove in the handover area, and the tablets to be handed over are adsorbed by the suction groove, so that the tablets smoothly enter the bottom of the second belt conveyor mechanism and expose the lower surface for image detection of the lower surface.

[0038] The suction mechanism in the present invention not only provides adsorption force for the belt conveyor mechanism, but also has a material sorting device functional module for collecting dust and debris generated by tablets in the material sorting device to ensure cleanliness in the detection machine.
