Description
Technical Field
[0001] This invention belongs to the field of automated filling technology, specifically relating to an automatic mixing and filling device and method for rod-shaped and tubular drugs. Background Technology
[0002] Each cartridge case requires a large amount of propellant, and the length of the rods must meet design standards. To ensure compliance with design requirements, the rods must be screened during the loading process. Traditional loading methods require manual operation, which presents problems such as a large volume of hazardous materials at the work site, a large number of workers, high labor intensity, and the batch product's propellant quality being greatly affected by subjective factors.
[0003] To this end, the patent specification with publication number CN109723575B discloses a free-loading method and technique for tubular propellant to achieve multiple thrust schemes. This belongs to the field of solid rocket motor propellant technology and is applicable to solid rocket motors used for simulating the dynamic armor-piercing velocity of armor-piercing warheads. It is mainly used to achieve the thrust schemes required for different simulated velocities of dynamic armor-piercing warheads. This method and technique includes a baffle plate and two sets of propellant grains. The baffle plate has five mounting holes on one side, for a total of ten mounting holes on both sides. By using two tubular propellant grains of different lengths, combined with the baffle plate, and selecting different combination methods, multiple thrust schemes can be achieved with a single engine. The outstanding advantages of this invention are its simple structure, safe assembly, and convenient use. The newly designed baffle plate can realize various combinations of multiple sets / multiple propellant grains, while avoiding many disadvantages of traditional multi-tube propellant mounting or insertion. It achieves the requirement of using a single engine to realize different thrust schemes and has great potential for widespread application.

[0016] The present invention also provides an automatic mixing and filling method for rod-shaped and tubular drugs, which is based on the above-mentioned automatic mixing and filling device for rod-shaped and tubular drugs, and includes the following steps:
[0017] 1) The rod-shaped drugs are loaded into the rod-shaped drug bin of the automatic rod-shaped drug sorting and conveying mechanism, and the tubular drugs are loaded into the tubular drug bin of the automatic tubular drug sorting and conveying mechanism. The first conveyor chain in the automatic rod-shaped drug sorting and conveying mechanism only allows a single piece of material from the rod-shaped drug bin to enter, and the second conveyor chain in the automatic tubular drug sorting and conveying mechanism only allows a single piece of material from the tubular drug bin to enter. When the rod-shaped or tubular drug material reaches the inspection station, it is inspected by the vision inspection system in the non-conforming product rejection mechanism. If the current material is detected as non-conforming, the movable rod of the rejection cylinder extends and pushes the material into the non-conforming product bin.
[0018] 2) The automatic mixing and filling mechanism for rod-shaped and tubular drugs is reset. At this time, one of the six filling zones separated by the star wheel is located directly below the cap, and another filling zone is connected to the discharge port of the hopper.
[0019] 3) The filling container with the bottom bag is placed in the designated position by the second gantry robot and held by the second gripper of the second gripper cylinder, while the blocking block restricts the filling container from moving backward.
[0020] 4) Rod-shaped and tubular drugs are fed into the filling area located directly below the pressure cap through the hopper in a certain quantity. After the filling area is filled, the first motor drives the star wheel to rotate 60 degrees, so that the new filling area is located directly below the pressure cap, realizing cyclic filling.
[0021] 5) The first horizontal push rod pulls the star wheel out of the filling container cylinder. After a certain amount of rod-shaped and tubular medicines are fed into the filling container cylinder through the hopper, the vertical push rod drives the pressure cap to move down and slowly press it against the discharge port at the top of the filling container cylinder. At the same time, the second motor drives the crank rocker mechanism to start, so as to ensure that the last filling material completely enters the filling container cylinder.
[0022] 6) After all the material has entered the filling container cylinder, the second transverse push rod drives the push plate to retract, thereby sending all the material in the filling container cylinder into the filling container.
[0023] 7) Fill the first layer of material in sequence according to the above steps. After filling is completed, the second gripper cylinder of the second truss robot opens, the second truss robot grabs the filling container and rotates it 90 degrees, places it on the tray, and transports it to the bag filling station. Then the first truss robot fills the top bag. At this point, the entire filling process is completed.
[0024] The beneficial effects of this invention are:
[0025] The present invention has a reasonable structural design, which automates the entire process of automatic mixing and loading of rod-shaped and tubular drugs, achieving the purpose of human-machine isolation, effectively controlling production quality, improving production efficiency, and reducing the threat to personal safety in the event of combustion or explosion.

9. An automatic mixing and filling method for rod-shaped and tubular drugs, implemented based on the automatic mixing and filling device for rod-shaped and tubular drugs as described in claim 8, characterized in that, Includes the following steps: 1) The rod-shaped drugs are loaded into the rod-shaped drug bin of the automatic rod-shaped drug sorting and conveying mechanism, and the tubular drugs are loaded into the tubular drug bin of the automatic tubular drug sorting and conveying mechanism. The first conveyor chain in the automatic rod-shaped drug sorting and conveying mechanism only allows a single piece of material from the rod-shaped drug bin to enter, and the second conveyor chain in the automatic tubular drug sorting and conveying mechanism only allows a single piece of material from the tubular drug bin to enter. When the rod-shaped or tubular drug material reaches the inspection station, it is inspected by the vision inspection system in the non-conforming product rejection mechanism. If the current material is detected as non-conforming, the movable rod of the rejection cylinder extends and pushes the material into the non-conforming product bin. 2) The automatic mixing and filling mechanism for rod-shaped and tubular drugs is reset. At this time, one of the six filling areas at the star wheel separator is located directly below the cap, and one filling area is connected to the discharge port of the hopper. 3) The filling container with the bottom bag is placed in the designated position by the second gantry robot and held by the second gripper of the second gripper cylinder, while the blocking block restricts the filling container from moving backward. 4) Rod-shaped and tubular drugs are fed into the filling area located directly below the pressure cap through the hopper in a certain quantity. After the filling area is filled, the first motor drives the star wheel to rotate 60 degrees, so that the new filling area is located directly below the pressure cap, realizing cyclic filling. 5) The first horizontal push rod pulls the star wheel out of the filling container cylinder. Then, a certain amount of rod-shaped and tubular medicines are fed into the filling container cylinder through the hopper. The vertical push rod drives the pressure cap to move down and slowly press it against the discharge port at the top of the filling container cylinder. At the same time, the second motor drives the crank rocker mechanism to start, so as to ensure that the last filling material completely enters the filling container cylinder. 6) After all the material has entered the filling container cylinder, the second transverse push rod drives the push plate to retract, thereby sending all the material in the filling container cylinder into the filling container. 7) Fill 2 to 4 layers of material in sequence according to the above steps. After filling is completed, the second gripper cylinder of the second truss robot opens, the second truss robot grabs the filling container and rotates it 90 degrees, places it on the tray, and transports it to the bag filling station. Then the first truss robot fills the top bag. At this point, the entire filling process is completed.
