Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a rejecting device. Background Art

[0002] Whether the dosage of Chinese herbal medicine is appropriate directly affects the efficacy of the medicine. The commonly used dosage is strictly regulated in the Pharmacopoeia of the People's Republic of China. If the dosage is too small, there will be no therapeutic effect; if the dosage is too large, poisoning symptoms may occur, which is harmful to human health.

[0003] During the packaging process of the drug assembly line packaging machine, the supply density of the drug material cannot always be consistent. When the density of the drug material changes, there will be more or less deviations in the dosage of the drug packaged in each bag. If the dosage in the bag is too small or too large, it needs to be removed before it is transferred to the next process.

[0004] At present, the dosage of drug packaging is generally checked by manual weighing. This method takes a long time, has low work efficiency, and has high labor intensity for workers on the production line. In addition, manual weighing is prone to inaccurate detection, which seriously affects production efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a system for automatically rejecting unqualified products in drug packaging to solve the above technical problems.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] The system for automatically rejecting unqualified products of medicine packaging dosage comprises a medicine bag conveyor belt with a baffle plate for conveying medicine bags, the medicine bag conveyor belt has a base and a medicine outlet, and also comprises a belt scale, the belt scale has a weighing sensor and a belt transmission mechanism, and the belt scale also has a feeding end and a discharging end; the height of the feeding end of the belt scale is lower than the height of the medicine bag conveyor belt discharging end; and also comprises a guide plate, which is a plane plate inclined downward along the medicine bag conveying direction, and is called a first guide plate, which is installed on the base of the medicine bag conveyor belt, the upper end of the first guide plate is connected to the medicine bag conveyor belt discharging end, and the lower end is connected to the feeding end of the belt scale, and the medicine bag slides from the medicine bag conveyor belt discharging end to the feeding end of the belt scale along the first guide plate;

[0008] A sorting conveyor is also arranged below the discharge end of the belt scale; the sorting conveyor includes a conveyor belt and a conveyor belt electric drive system with forward and reverse functions, the conveyor belt electric drive system has a forward switch and a reverse switch, the forward switch has a forward control signal input end, and the reverse switch has a reverse control signal input end; the belt scale is provided with a standard-reaching signal output end and an over-standard signal output end, and the standard-reaching signal output end and the over-standard signal output end interlock the output signal; the standard-reaching signal output end is connected to the forward control signal input end, and the over-standard signal output end is connected to the reverse control signal input end; a second guide plate is arranged downwardly inclined along the conveying direction of the belt scale, the second guide plate is installed on the belt scale, the upper end of the second guide plate is connected to the discharge end of the belt scale, and the lower end of the second guide plate is connected to the conveyor belt of the sorting conveyor, and the medicine package slides from the discharge end of the belt scale to the conveyor belt of the sorting conveyor along the second guide plate; a qualified product receiving device is arranged in the forward rotation direction of the conveyor belt; and an unqualified product receiving device is arranged in the reverse rotation direction of the conveyor belt.

[0009] In the above design, the function of the medicine bag conveyor belt with a baffle plate for conveying medicine bags is to lift the medicine bags to a high position so that the medicine bags have a certain potential energy. The subsequent medicine bags can circulate in different functional components through the drop under the action of the potential energy. The medicine bags first pass through a belt scale that can weigh the weight of the medicine bags. During the time when the medicine bags pass through the belt scale, the weight of the medicine bags is weighed, and one of the signals of reaching the standard or exceeding the standard is issued according to the current weight of the medicine bags; the medicine bags slide onto the conveyor belt of the sorting conveyor through the second guide plate. The sorting conveyor has a conveyor belt electric drive system with forward and reverse functions. The forward and reverse rotations are controlled by the forward switch and the reverse switch, respectively. The forward switch and the reverse switch have a forward control signal input terminal and a reverse control signal input terminal, respectively. The reaching signal is connected to the forward control signal input terminal, and the exceeding signal is connected to the reverse control signal input terminal. At this point, the medicine bags that meet the standard and the medicine bags that exceed the standard are transmitted to different directions on the sorting conveyor.

[0010] Furthermore, it also includes a control system, which includes a weight signal input terminal, a forward control signal output terminal and a reverse control signal output terminal; the belt scale has a weight signal output terminal; the weight signal output terminal is connected to the weight signal input terminal; the forward control signal output terminal is connected to the forward control signal input terminal; and the reverse control signal output terminal is connected to the reverse control signal input terminal.

[0011] In the utility model, a control system is adopted to access the weight signal of the belt scale, and the weight range of products that meet the standards and products that exceed the standards can be flexibly set, so that the application can adapt to the sorting of different medicines, shorten the sorting adjustment time, and improve production efficiency.

[0012] Furthermore, the height of the baffle plate of the medicine bag conveyor belt is 6 to 10 mm.

[0013] In the utility model, the function of the material baffle is to prevent the medicine packages from sliding down when the medicine package conveyor belt conveys the medicine packages to a higher place, causing the medicine packages on the conveyor belt to pile up. Once the medicine packages are piled up, they will inevitably be judged as over-standard products when passing the belt scale. Therefore, the height of the material baffle is too low and it will inevitably fail to prevent the medicine packages from sliding down.

[0014] Furthermore, the material conveying direction of the belt scale and the conveying direction of the sorting conveyor are perpendicular to each other.

[0015] In the utility model, the material conveying direction of the belt scale and the conveying direction of the sorting conveyor are perpendicular to each other, which facilitates the subsequent disposal after the separation of qualified products and substandard products. The qualified products flow to the next process, and the substandard products are stored nearby.

[0016] Furthermore, the inclination angle of the second material guide plate is between 50° and 65°.

[0017] In the present invention, the function of the second guide plate is to guide the medicine packages flowing out of the belt scale discharge end to slide onto the sorting conveyor. The medicine packages have been weighed when flowing through the belt scale, and the judgment of whether they are qualified products or over-standard products has been obtained. The sorting conveyor has received the instruction of forward or reverse rotation. If the medicine package stops at the second guide plate, the current medicine package will meet the next medicine package at the second guide plate. If the previous medicine package is an over-standard product and the next medicine package is a qualified product, the two medicine packages will be transported by the sorting conveyor as qualified products. In this case, the over-standard products cannot be eliminated. Therefore, the inclination angle of the second guide plate needs to be set larger to ensure that the medicine package cannot be retained on the second guide plate and slides onto the conveyor belt of the sorting conveyor as soon as possible.

[0018] Furthermore, the qualified product receiving device is a material conveyor, which has a conveyor belt and a feeding end for feeding materials; the sorting conveyor is provided with a third guide plate inclined downward along the conveying direction of the qualified products, and the qualified products slide along the third guide plate to the feeding end.

[0019] In the utility model, qualified products flow to the next process through the material conveyor, the height of the material conveyor is lower than the height of the conveyor belt of the sorting conveyor, and the qualified products slide to the material conveyor through the third guide plate.

[0020] Furthermore, the unqualified product receiving device is a storage box; the sorting conveyor is provided with a fourth guide plate inclined downward along the conveying direction of the unqualified products, and the unqualified products slide into the storage box along the fourth guide plate.

[0021] In the utility model, the over-standard products slide into the storage box through the fourth material guide plate.

[0022] The utility model introduces a belt scale to complete weighing during the drug package transmission process, and classifies the drug packages into qualified products or over-standard products according to their weight. When the drug packages flow to the sorting conveyor, the belt scale also synchronously gives the sorting conveyor a forward or reverse instruction, so that the qualified products and over-standard products are respectively conveyed in opposite directions on the sorting conveyor. Its beneficial effect is that the belt scale weighs the drug package dosage in a short time with high accuracy, and the products judged to be over-standard are automatically transported to the over-standard product storage box on the sorting conveyor. This process is highly efficient, does not require manual intervention, saves labor costs, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
