For example, the first sealing box 1 and the second sealing box 2 may be glove box structures, and in the packaging process, the first sealing box 1 and the second sealing box 2 are both in a vacuum environment or in a negative pressure environment, and the specific pipeline structure for maintaining the negative pressure environment is not limited in this embodiment, and any pipeline capable of realizing any negative pressure environment may be realized.
Further, it is specifically explained that in the present embodiment, both the first seal case 1 and the second seal case 2 are in the isolated state, that is, the first seal case 1 and the second seal case 2 can be kept in the isolated state regardless of whether the station opening 10 is in the open or closed state.
The material transferring device comprises a first material transferring device 3 positioned in the first sealed box body 1, after the sealing cover of the station opening 10 is removed and the station opening 10 is opened, the first material transferring device 3 transfers the radioactive material to the station opening 10 from a designated area in the first sealed box body 1, and the radioactive material is placed into a plastic package bag positioned in the second sealed box body 2 through the station opening 10 and hermetically sleeved on the outer edge of the station opening 10;

The remote control automatic packaging system provided by the embodiment realizes that unpacked radioactive materials are all located in the first sealed box body 1 by arranging the first sealed box body 1 and the second sealed box body 2 which are isolated from each other, and enters a plastic package bag inside the second sealed box body 2 for sealing treatment through a station port 10 communicated with the first sealed box body and the second sealed box body, and then is transported inside the second sealed box body 2. In the packaging process, each device inside the sealed box body is controlled remotely and operated automatically by a control device arranged outside the sealed box body, so that full automation of the radioactive material packaging process is ensured, and pollution to the second sealed box body 2 in the packaging process is avoided.
Example two
During nuclear facility operations and production processes, such as radioactive ore mining, processing and refining, nuclear fuel preparation, reactor operations, radioisotope production and processing, nuclear fuel chemical treatment and post-processing, and radioactive waste disposal, radioactive aerosols are generated, which contaminate the air at the nuclear facility workplace and environment with radioactive aerosols. Thus, referring to fig. 1-5, the remote control automatic packaging system for radioactive materials provided in this embodiment includes, in addition to all the devices in the first embodiment, optionally, a radiation detection device electrically connected to the control device and located inside the second sealed box 2, so as to perform radiation detection on the packaged radioactive materials and feed back the radiation detection to the control device in real time, where the radiation detection is a radioactive aerosol detection, and the staff inhales the air containing the radioactive aerosol, and part of the radioactive material particles will stay in the body, so that the internal radiation is more harmful to the human body than the external radiation, and therefore, the radioactive aerosol monitoring is of great importance to ensure the health of the staff.
The radioactive aerosol is predominantly an alpha aerosol. The radioactive aerosol detection item may include, but is not limited to: alpha aerosol concentration monitoring, particle size distribution detection, evaluation of detection results, and the like. Because there is a possibility that the plastic package is not completely packaged in the heat sealing process of the plastic package, after the heat sealing is finished, a radiation detection device is adopted to detect the radiation dose of the plastic package packaged with the radioactive material, the detection information is fed back to a control device in real time, when the control device judges that the detection result is greater than a preset value, the control device sends the information that the plastic package is an unqualified product, and controls a corresponding execution device to carry out secondary bagging operation on the plastic package, so that the bagging product coming out of the automatic packaging system is ensured not to have any radioactive substance, and the personal safety of operators is effectively protected. Optionally, the automated packaging system further comprises a plastic bag storage library 61 in communication with the second sealed box 2. The plastic package storage 61 may be disposed inside the second sealed container 2, or may be disposed in another sealed space communicating with the second sealed container 2, which is not limited thereto.
Referring to fig. 3, the plastic package bag feeding device 6 includes: a lifting mechanism 62 arranged on the plastic package storage warehouse, a translation mechanism 63 connected to the lifting mechanism 62, a forking mechanism 64 arranged on the translation mechanism 63, and an automatic bagging mechanism 65; wherein, the liquid crystal display device comprises a liquid crystal display device,
the translation mechanism 63 moves along the Z axis under the drive of the lifting mechanism 63, and the forking mechanism 64 moves along the Y axis along with the translation mechanism 63; the forking mechanism 64 moves along the X axis relative to the translation mechanism 63 to fork the plastic package from the plastic package storage library 61; the automatic bagging mechanism 65 is located inside the second sealed box 2 and is disposed near the station opening 10, and is used for hermetically sleeving the plastic package bag from the forking mechanism 64 at the outer edge of the station opening 10.
The lifting mechanism 62 may be, for example, a lifting cylinder, the translation mechanism 63 may be, for example, a screw-nut transmission, and the fork mechanism 64 may be, for example, driven by an air motor. Such a translation or lifting mechanism for linear movement is not limited in this embodiment.
Optionally, the automated packaging system provided in this embodiment may further include a cap removing device 5 electrically connected to the control device; when the plastic package bag feeding device 6 is used for sleeving the plastic package bag at the outer edge of the station opening 10, the cover taking device 5 can remove the sealing cover at the station opening 10 to open the station opening 10, and at this time, the plastic package bag is hermetically sleeved at the outer edge of the station opening 10, so that even if the sealing cover at the station opening 10 is removed, the first sealing box body 1 and the second sealing box body 2 still keep a mutually isolated state, and radiation pollutants of the first sealing box body 1 cannot enter the second sealing box body 2.
After the cover removing device removes the sealing cover, the first material transferring device 3 can put the radioactive materials in the appointed area in the first sealing box body 1 into the plastic package bag through the opened station opening 10 for packaging.
Referring to fig. 4 and 5, after the radioactive material has been put into the plastic package, the subsequent operation is performed by the heat-seal shearing device 7 under the instruction sent by the control device. In particular, the heat seal and shear device 7 may comprise a heat seal assembly and a shear assembly.
After the radioactive materials are placed in the plastic package bag by the heat sealing assembly, the plastic package bag is heat sealed below the station opening 10.
The shearing assembly is used for shearing the plastic package bag after the heat sealing assembly completes the heat sealing, so that the top of the plastic package bag filled with the radioactive material is sealed, the bottom of the plastic package bag remaining below the station is also sealed, and the isolation state of the first sealed box body 1 and the second sealed box body 2 is ensured.
It should be noted that, because the radioactive material enters the plastic package through the station 10, the inside of the plastic package is in a communication state with the first sealed box 1 and is in a contaminated area, so that the heat sealing assembly seals an area with a certain width instead of a line when performing heat sealing, and therefore, when the shearing assembly shears, the heat sealing area is sheared, so that the sheared plastic package is sealed, and meanwhile, the tail of the residual plastic package at the station is sealed after shearing, and the first sealed box 1 and the second sealed box 2 are still kept in an isolated state of non-communication.
For example, when the heat-sealing assembly performs heat sealing on the heat-sealing area of the plastic package bag, the sealing of the area with a certain width can be realized by forming a plurality of heat seals, such as three heat seals, and then the shearing assembly shears from the middle heat seal, so that the radioactive pollutant in the first sealed box body is prevented from entering the second sealed box body 2, and the radioactive pollutant is prevented from leaking.
The automatic heat sealing and shearing operation is adopted, so that the operation flow is simplified, and the automatic heat sealing and shearing device can be completely suitable for the packaging operation of radioactive materials in the sealed box body.
In particular, referring to fig. 5, a shear assembly may be provided on the heat seal assembly and move in synchronism therewith; the heat seal assembly and the shearing assembly can move along the horizontal direction and the vertical direction so as to seal the plastic package and shear after sealing.

The first and second heat sealer floors 303 and 305 simultaneously slide inward or simultaneously slide outward on the Z-axis slider 301 with the two X-axis sliders 302, respectively, to seal the plastic sealed bags.
