This allows for the rapid and efficient transport of objects to be irradiated to the irradiation area of ​​the irradiation accelerator, and the rapid and efficient transport of irradiated objects to the next station, thereby improving the efficiency of the irradiation accelerator in irradiating objects.

[0006] In some possible implementations of this application, the transmission system further includes a flipping device disposed on the circulating transmission line and located downstream of the irradiation accelerator on the circulating transmission line.

[0015] The control method for the transmission system of an irradiation accelerator provided in this application controls the conveyor line to transport the object to be irradiated to the circulating conveyor line, and controls the transfer device to transfer the object from the conveyor line to the circulating conveyor line. The method can control the pace at which the transfer device transfers the object to the circulating conveyor line based on the number of objects to be irradiated on the circulating conveyor line, thereby reducing congestion on the circulating conveyor line. Furthermore, controlling the circulating conveyor line to move the object through the irradiation zone at a preset speed allows for irradiation of the object for an appropriate duration, improving the irradiation quality. Simultaneously, controlling the transfer device to transfer the irradiated object to the conveyor line allows for rapid transport of the irradiated object to the next station.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] This application provides a transport system for an irradiation accelerator. This system can transport numerous objects to be irradiated along a preset path and at a preset speed to the irradiation zone of the accelerator, and can rapidly transfer irradiated objects that have already been irradiated, thereby improving the efficiency of the irradiation accelerator in irradiating objects. (Refer to...) Figure 1 , Figure 1 This is a schematic diagram of the structure of the transmission system for an irradiation accelerator provided in this application. The transmission system for an irradiation accelerator provided in this application can be used in irradiation accelerators for high-energy electron beam irradiation or irradiation accelerators for X-ray beam irradiation. This application does not limit the application scenarios of the transmission system. The following describes the transmission system for an irradiation accelerator provided in this application with reference to the examples in the accompanying drawings.

[0027] The transmission system for an irradiation accelerator provided in this application includes: a circulating transmission line 1, a conveying transmission line 2, and a transfer device 3; wherein, the circulating transmission line 1 is arranged along the arrangement path of the irradiation accelerator and is circular, and the circulating transmission line 1 is used to transport irradiated material to the irradiation area of ​​the irradiation accelerator; at least a portion of the conveying transmission line 2 is arranged adjacent to at least a portion of the circulating transmission line 1, and the circulating transmission line 1 is used to transport irradiated material from a temporary storage location to the circulating transmission line 1; the transfer device 3 is disposed between the conveying transmission line 2 and the circulating transmission line 1, and a portion of the transfer device 3 is capable of reciprocating between the conveying transmission line 2 and the circulating transmission line 1 to transfer irradiated material between the conveying transmission line 2 and the circulating transmission line 1.

[0028] In some embodiments, the circulating transmission line 1 can transport the object to be irradiated to the irradiation zone of the irradiation accelerator so that the object can receive irradiation from a high-energy electron beam or X-ray beam, thereby performing sterilization, material modification, environmental treatment, etc. on the object to be irradiated.

[0029] For example, the shape of the circulating conveyor line can be set according to the configuration of the irradiation accelerator, and a portion of the circulating conveyor line can be located within the irradiation zone of the irradiation accelerator. For instance, the circulating conveyor line can be configured as a loop, where the beginning and end of the loop are connected to form a complete circle. The object to be irradiated can move along the circulating conveyor line from its starting position, and after completing one loop, it can return to its starting position. The circulating conveyor line 1 can be a circular loop, or it can be a structure including straight sections and curved sections. This application embodiment does not limit the specific loop shape of the circulating conveyor line 1.

[0030] In another example, the circulating conveyor line can employ a structure including a support frame, a drive mechanism, and a transmission assembly. The support frame can be a frame structure. The drive mechanism can include an electric motor or engine, which can be fixedly mounted on the support frame. The transmission assembly can be a structure including a transmission element and a transmission component. The transmission element can be a gear set, chain and sprocket, belt and pulley, etc.; the transmission component can be a conveyor belt, conveyor roller, etc., which can be rotatably mounted on the support frame and then connected to the drive mechanism via the transmission element. Thus, the drive mechanism can drive the transmission assembly to move on the support frame, thereby moving the irradiated object placed on the transmission assembly along a predetermined path.

[0031] In some embodiments, the conveyor line 2 can transport materials to be irradiated from a temporary storage location to the vicinity of the circulating conveyor line 1. For example, materials to be irradiated that have come off or come off the production line can be transported to the vicinity of the circulating conveyor line 1 via the conveyor line 2. Materials to be irradiated stored in a storage warehouse can also be transported to the vicinity of the circulating conveyor line 1 via the conveyor line 2.

[0032] For example, the shape of the conveying line 2 can be set according to the space between the circulating conveying line and the temporary storage place of the object to be irradiated. For example, the conveying line 2 can be set as a structure including multiple straight sections and multiple turning sections, and two sections can be connected at an angle to each other through the turning sections.

[0033] In another example, the extension shape of at least a portion of the conveying line 2 can be made to match the extension shape of at least a portion of the circulating conveying line 1. For example, a section of the circulating conveying line 1 can be made straight, and a section of the conveying line 2 can also be made straight. Then the straight sections of the circulating conveying line 1 and the conveying line 2 can be arranged adjacent to each other and parallel to each other.

[0034] In another example, the conveyor line 2 can be configured with a structure similar to the circulating conveyor line 1, that is, the conveyor line 2 can also include a support, a drive mechanism, and a conveyor assembly. The drive mechanism can then drive the conveyor assembly to move on the support, thereby moving the object to be irradiated and the irradiated object placed on the conveyor assembly along the arranged path.

[0035] In some embodiments, a transfer device 3 may be provided near the adjacent portions of the circulating transmission line 1 and the conveying transmission line 2 to transfer the object to be irradiated on the conveying transmission line 2 to the circulating transmission line 1, or to transfer the irradiated object that has already been irradiated on the circulating transmission line 1 to the conveying transmission line 2. For example, the transfer device 3 may be located in the middle of the adjacent portions of the circulating transmission line 1 and the conveying transmission line 2.

[0036] For example, the transfer device 3 may include a conveying component (such as a belt, conveyor roller, etc.) and a toggle component. The conveying component may be disposed between the circulating transmission line 1 and the conveying transmission line 2. One end of the conveying component is connected to the side of the circulating transmission line 1, and the other end is connected to the side of the conveying transmission line 2. The toggle component may be disposed on the circulating transmission line 1 and the conveying transmission line 2. The toggle component may swing relative to the circulating transmission line 1 or the conveying transmission line 2 to move the object to be irradiated on the conveying transmission line 2 to the conveying component, or to move the irradiated object on the circulating transmission line 1 to the conveying component. Thus, the object to be irradiated may be transferred to the circulating transmission line 1, or the irradiated object may be transferred to the conveying transmission line 2, through the conveying component.

[0037] The transmission system for an irradiation accelerator provided in this application embodiment allows for the sequential transport of numerous objects to be irradiated to the irradiation zone of the accelerator via a circular transmission line 1, facilitating the sequential irradiation of these objects. Furthermore, the circular transmission line 1 is ring-shaped, allowing the objects to be irradiated to move at least two revolutions along it, thus enabling multiple irradiations. With at least a portion of the conveyor line 2 adjacent to at least a portion of the circular transmission line 1, the objects to be irradiated can be rapidly transported from a temporary storage location to the vicinity of the circular transmission line 1 via the conveyor line 2. Meanwhile, a transfer device 3 is provided between the circulating conveyor line 1 and the conveying conveyor line 2 to facilitate the rapid transfer of the object to be irradiated from the conveying conveyor line 2 to the circulating conveyor line 1, or the rapid transfer of the irradiated object from the circulating conveyor line 1 to the conveying conveyor line 2. This allows the object to be irradiated to be transported to the irradiation area of ​​the irradiation accelerator quickly and efficiently, and the irradiated object to be transported to the next station quickly and efficiently, thereby improving the efficiency of the irradiation accelerator in irradiating the object to be irradiated.

[0038] In some possible embodiments of this application, the transmission system further includes a flipping device 4, which is disposed on the circulating transmission line 2 and located downstream of the irradiation accelerator on the circulating transmission line 2. The flipping device 4 is used to flip the irradiated material.

[0039] In some embodiments, a flipping device 4 may be provided in the transmission system to flip the irradiated object so that the surface of the irradiated object that has not been directly irradiated faces the irradiation accelerator.

[0040] For example, the flipping device 4 can be disposed on the circulating conveyor line 1. Specifically, it can be disposed on the downstream portion of the circulating conveyor line 1, that is, on the portion of the circulating conveyor line 1 located after the irradiation accelerator. This allows the flipping device 4 to flip the irradiated material after it has been transported by the circulating conveyor line 1 past the irradiation accelerator. Alternatively, the flipping device 4 can be disposed on the portion of the circulating conveyor line 1 adjacent to the conveyor line 2.

[0041] In another example, the flipping device 4 can be configured to include a clamping assembly and a driving assembly. The driving assembly can be fixed above the circulating transport line 1, and the clamping assembly can include two grippers that can move closer or further apart. The clamping assembly is mounted on the driving assembly, which can drive the clamping assembly to rotate. Thus, after the irradiated object reaches the position of the flipping device 4, the clamping assembly can be controlled to first clamp the irradiated object, and then the driving assembly can be controlled to drive the clamping assembly to rotate, thereby rotating the irradiated object by 90°, 180°, etc. Finally, the flipped irradiated object is placed back on the circulating transport line 1. The irradiated object, having undergone one irradiation, can then be transported again to the irradiation zone of the irradiation accelerator via the circulating transport line 1 to complete a second irradiation.

[0042] The transmission system for an irradiation accelerator provided in this application embodiment has a flipping device 4 on the circulating transmission line 1. The flipping device 4 can flip the irradiated object so that the surface of the irradiated object that has not been directly irradiated faces the irradiation accelerator. This allows for secondary irradiation and sterilization of the irradiated object, which is beneficial to improving the effect and efficiency of irradiation and sterilization of the irradiated object.

[0043] In some possible embodiments of this application, such as Figure 1 As shown, the circulating transmission line 2 includes a shielded section 11 and an external section 12 connected to each other; the transmission system also includes a shield 5, which encloses a shield cavity 51. The shape of the shield cavity 51 matches the extension path of the shielded section 11. The shielded section 11 is located inside the shield cavity 51, and the external section 12 is located outside the shield cavity 51 and adjacent to the transmission line 2. The shield 5 is used to protect against radiation leakage.

[0044] In some embodiments, a shielding element 5 can be provided in the transmission system, that is, a shielding element 5 can be provided for the circulating transmission line 1 and the irradiation accelerator, so as to block and absorb high-energy rays, such as X-rays and electron beams, thereby protecting personnel and the environment from radiation hazards. For example, the shielding element 5 can be made of high-density tungsten alloy, boron-containing polyethylene composite material, or lead and concrete.

[0045] For example, the shape of the shield 5 can be set according to the extension path of the circulating transmission line 1 and the location of the irradiation accelerator, so that the shield 5 can enclose and form a shield cavity 51 that can accommodate a part of the circulating transmission line 1 and the irradiation accelerator. For example, the shield cavity 51 can be set in the form of a semi-annular shape that matches a part of the circulating transmission line 1, so that the shield cavity 51 has an outlet 14 and an inlet 13 communicating with the outside of the shield 5.

[0046] In another example, the circular transmission line 1 can be configured as a shielded section 11 and an external section 12, which are connected end-to-end to form a complete loop. The shielded section 11 is located inside the shielded cavity 51, and the external section 12 is located outside the shielded cavity 51. The shielded section 11 can be configured as a structure comprising multiple approximately "S-shaped" segments, and the external section 12 can be configured as an approximately straight line. The external section 12 can be arranged parallel to and spaced apart from the transmission line 2.

[0047] The transmission system for an irradiation accelerator provided in this application embodiment improves the safety of the transmission system by providing a shielding element 5 to the circulating transmission line 1. This shielding element 5 absorbs and blocks high-energy rays and other radioactive radiation generated by the irradiation accelerator. Furthermore, the circulating transmission line 1 is configured with a shielded section 11 and an outer section 12, facilitating the placement of the outer section 12, located outside the shielding cavity 51, adjacent to the transport transmission line 2. This allows the object to be irradiated to be transferred via the transfer device 3 to the portion where the outer section 12 and the shielded section 11 connect.

[0048] In some possible embodiments of this application, such as Figure 1 As shown, the transfer device 3 includes a first transfer member 31 and a second transfer member 32; the first transfer member 31 is disposed adjacent to the downstream end of the external section 12, and the first transfer member 31 is used to transfer the object to be irradiated on the conveying line 2 to the downstream end of the external section 12; the second transfer member 32 is disposed adjacent to the upstream end of the external section 12, and the second transfer member 32 is used to transfer the irradiated object on the upstream end of the external section 12 to the conveying line 2.

[0049] In some embodiments, the transfer device 3 can be configured to include a first transfer member 31 and a second transfer member 32. The structures of the first transfer member 31 and the second transfer member 32 can be the same or different. For example, both the first transfer member 31 and the second transfer member 32 can be configured to include a robotic arm and a suction cup. The robotic arm can be a four-axis robotic arm or a six-axis robotic arm. The robotic arm can be fixed between the external section 12 and the conveying line 2, and the suction cup can be fixed to the end of the robotic arm.

[0050] For example, the first transfer member 31 can be positioned near the downstream end of the external section 12, that is, near the upstream end of the shielding section 11, so that the first transfer member 31 is located near the entrance 13 of the shielding cavity 51. In this way, the object to be irradiated, which is conveyed from the conveyor line 2 to the location of the first transfer member 31, can be transferred to the downstream end of the external section 12 via the first transfer member 31. For example, the suction cup is controlled to adsorb and fix the object to be irradiated on the conveyor line 2, and then the robotic arm is controlled to move the suction cup and the object to be irradiated to the tray 7 at the downstream end of the external section 12, and then the suction cup is controlled to release the object to be irradiated onto the tray 7.

[0051] In another example, the second transfer member 32 can be positioned near the upstream end of the outer section 12, that is, near the downstream end of the shielding section 11, so that the second transfer member 32 is located near the outlet 14 of the shielding cavity 51. In this way, the irradiated material transported from the shielding section 11 to the outer section 12 can be transferred via the second transfer member 32 to the output section 23 of the transport line 2. For example, the irradiated material can be controlled to adhere to the tray 7 located on the outer section 12 using a suction cup, and then the robotic arm can be controlled to move the suction cup and the material to be irradiated to the output section 23 of the transport line 2. Finally, the suction cup can be controlled to release the irradiated material onto the output section 23.

[0052] The transmission system for an irradiation accelerator provided in this application embodiment includes a first transfer member 31 and a second transfer member 32. The first transfer member 31 and the second transfer member 32 can be respectively set at the upstream end and the downstream end of the external section 12. Thus, the first transfer member 31 and the second transfer member 32 can transfer the object to be irradiated or the object already irradiated on the transmission line 2 and the external section 12 at two positions, thereby improving the transfer efficiency of the object to be irradiated and the object already irradiated.

[0053] In some possible embodiments of this application, such as Figure 1As shown, the conveying line 2 includes a conveying section 21, which is arranged adjacent to the circulating conveying line 2; the conveying system also includes a stop device (not shown in the figure), which is arranged on the circulating conveying line 2 and located at a position corresponding to the transfer device 3. The stop device is used to restrict the pallet 7 located on the circulating conveying line 2 from moving with the circulating conveying line 2.

[0054] In some embodiments, the conveyor line 2 can be configured to include different segments, each of which can operate independently. That is, each segment of the conveyor line 2 can operate independently or stop operating independently.

[0055] For example, the portion of the conveyor line 2 adjacent to the circulating conveyor line 1 can be designated as a transmission segment 21, which is adjacent to and parallel to the outer segment 12 of the circulating conveyor line 1. Multiple transmission segments 21 parallel to the outer segment 12 can be arranged sequentially and connected. Each transmission segment 21 can be equipped with a separate drive mechanism to drive the belt or conveyor roller of each transmission segment 21 to rotate. For instance, two transmission segments 21 can be arranged adjacent to the outer segment 12, one adjacent to the first transfer member 31 and the other adjacent to the second transfer member 32. Alternatively, at least three transmission segments 21 can be arranged adjacent to the outer segment 12, with one of the at least three transmission segments 21 adjacent to the first transfer member 31 and the other adjacent to the second transfer member 32. That is, each independently controllable transmission segment 21 is located within the picking range of the first transfer member 31 and the second transfer member 32.

[0056] In some embodiments, a stop device may be provided on the circulating conveyor line 1 to stop the tray 7 on the circulating conveyor line 1 from moving along the conveying direction Z (indicated by the unidirectional arrow in the figure) with the circulating conveyor line 1. For example, a stop device may be provided in the area of ​​the circulating conveyor line 1 corresponding to the first transfer member 31, and another stop device may be provided in the area of ​​the circulating conveyor line 1 corresponding to the second transfer member 32.

[0057] For example, the stopping device can be configured as a structure including a stop and a drive. The drive can be a motor, and the stop can be rod-shaped or plate-shaped. The motor can be fixed next to the circulating transmission line 1, and the stop can be fixed to the output shaft of the motor, or the stop can be rotatably positioned next to the circulating transmission line 1. The motor and the stop can be connected by a transmission such as gears or chains. In this way, the drive can drive the stop to swing relative to the circulating transmission line 1 in the horizontal plane, so that the stop rotates into the movement path of the tray 7 to prevent the tray 7 from moving with the circulating transmission line 1 (at this time, the tray 7 slides relative to the circulating transmission line 1), or the stop rotates to the side of the circulating transmission line 1 to release the obstruction to the tray 7, allowing the tray 7 to move with the circulating transmission line 1.

[0058] In another example, the stopping device can be configured as a structure including a lifting member and a driving member. The lifting member can be slidably mounted on the circulating transmission line 1 in a vertical direction, and the driving member can be connected to the lifting member in a transmission manner. In this way, the lifting member can be driven by the driving member to move in a vertical direction to lift the tray 7 on the circulating transmission line 1 and detach it from the circulating transmission line 1, or to lower the lifted tray 7 onto the circulating transmission line 1.

[0059] Thus, when multiple items being transported on conveyor line 2 include items requiring irradiation, when the item reaches the conveyor section 21 adjacent to the first transfer member 31, the conveyor section 21 can be controlled to stop moving, and the stop device adjacent to the first transfer member 31 can be controlled to perform a stop action, causing a tray 7 to stop moving relative to the first transfer member 31. Then, the first transfer member 31 can be controlled to pick up the item to be irradiated from the conveyor section 21 and transfer it to the tray 7. Then, the conveyor section 21 can be controlled to continue moving, and the stop device can be controlled to perform a release action, allowing the tray 7 carrying the item to be irradiated to continue moving with the circulating conveyor line 1 until the item passes through the irradiation zone of the irradiation accelerator.

[0060] After the object to be irradiated has been irradiated in the irradiation zone of the irradiation accelerator, when the tray 7 holding the irradiated object reaches the picking range of the second transfer member 32 along the circulating conveyor line 1, the stop device corresponding to the second transfer member 32 can be controlled to perform a stop action, so that the tray 7 holding the irradiated object on the circulating conveyor line 1 stops moving relative to the second transfer member 32, and the conveyor section 21 adjacent to the second transfer member 32 stops moving. Then, the second transfer member 32 is controlled to pick up the irradiated object on the tray 7 and transfer the irradiated object to the conveyor section 21, and then the irradiated object is transported to the next station through the conveyor section 21.

[0061] The transmission system for an irradiation accelerator provided in this application embodiment includes a transmission section 21 adjacent to the circulating transmission line 1 in the conveying transmission line 2. The transmission system also includes a stop device corresponding to the transfer device 3. After the items on the transmission section 21 reach the picking range of the transfer device 3, the transmission section 21 can be controlled to stop moving, so that the transfer device 3 can pick up the object to be irradiated or place the irradiated object stably on the transmission section 21. Furthermore, the circulating transmission line 1 is provided with a stop device corresponding to the transfer device 3. The stop device can prevent the tray 7 on the circulating transmission line 1 from moving relative to the second transfer member 32, thereby facilitating the transfer device 3 to place the object to be irradiated on the tray 7 or to pick up the irradiated object from the tray 7. This allows for accurate and stable sorting and transfer of the objects to be irradiated from the items on the conveying transmission line 2, and accurate and stable transfer of the irradiated object on the circulating transmission line 1 to the transmission section 21.

[0062] In some possible embodiments of this application, such as Figure 1 As shown, the transmission line 2 also includes a buffer section 24, which is connected to the transmission section 21. The buffer section 24 is located upstream of the transmission section 21, and the transmission section 21 and the buffer section 24 are configured to operate independently.

[0063] In some embodiments, multiple buffer sections 24 can be provided in the upstream portion of the conveyor line 2, and the multiple buffer sections 24 are arranged and connected sequentially. Each buffer section 24 can be provided with a separate drive mechanism to drive the belt or conveyor roller of each buffer section 24 to rotate. Each transmission section 21, each buffer section 24, the first transfer member 31, the second transfer member 32, and the circulating transmission line 1 can be provided with a separate lower-level machine, thereby allowing individual control of the movement of each transmission section 21, each buffer section 24, the first transfer member 31, the second transfer member 32, and the circulating transmission line 1, so that the movement between the various parts is not subject to any necessary temporal sequence restrictions.

[0064] For example, buffer segment 24 can be positioned upstream of transmission segment 21, and adjacent buffer segments 24 can be connected to transmission segment 21. The arrangement of multiple buffer segments 24 can be configured according to the available space in the transmission system. For instance, multiple buffer segments 24 can be arranged in an approximately "S-shape" on one side of shield 5 to reduce the space occupied by the multiple buffer segments 24. In this way, after placing items on buffer segments 24, numerous items on multiple buffer segments 24 can be transferred step-by-step. For example, if multiple items are scattered across multiple buffer segments 24, multiple items can be first transported to the buffer segment 24 closest to transmission segment 21 until the buffer segment 24 closest to transmission segment 21 is full, and then items can be transported to an upstream buffer segment 24. Thus, it is not necessary to consider whether there are items on transmission segment 21, and items can be continuously transported to buffer segments 24 for temporary storage. Then, based on the number of objects to be irradiated and objects already irradiated on the transmission segment 21 and the circulating transmission line 1, the buffer segment 24 is controlled to transport the items to the transmission segment 21 in an orderly manner.

[0065] Another example is the leveling mechanism installed on buffer segment 24, which flattens the item to adjust its shape. For instance, the leveling mechanism could be a vibration mechanism that vibrates a suitable item to make its overall shape flatter and reduce its overall thickness. Alternatively, the leveling mechanism could be a height-limiting mechanism that restricts items exceeding a certain height from passing through, rotating them to a lower height by tipping or rolling them over, thus ensuring the item's height perpendicular to the irradiated surface meets irradiation requirements.

[0066] In another example, an access segment 22 can be set upstream of the buffer segment 24. One end of the access segment 22 is matched with the buffer segment 24, allowing the access segment 22 to be connected to the buffer segment 24. The other end of the access segment 22 is matched with the production line of the item, allowing the other end of the access segment 22 to be connected to the production line, etc. A mechanical locking structure and an electrical connection interface can be set in the access segment 22. The mechanical locking structure securely connects the access segment 22 to the production line, and the electrical connection interface electrically connects the transmission system to the production line.

[0067] In another example, an output segment 23 can be provided downstream of the transmission segment 21. One end of the output segment 23 is matched with the transmission segment 21, allowing the output segment 23 to be connected to the transmission segment 21. The other end of the output segment 23 is matched with a packaging line or similar device, allowing the other end of the output segment 23 to be connected to the packaging line or similar device. A mechanical locking structure and an electrical connection interface can be provided in the output segment 23 to securely connect the output segment 23 to the packaging line via the mechanical locking structure, and to electrically connect the transmission system to the packaging line via the electrical connection interface.

[0068] The transmission system for an irradiation accelerator provided in this application embodiment includes a buffer section 24 located upstream of the transmission section 21 in the transmission line 2. The buffer section 24 can be used to transport items step by step, and the buffer section 24 can be controlled to stop moving so that items can be temporarily stored on the buffer section 24. This facilitates the control of the movement of the buffer section 24 according to the operation of the transmission section 21, the circulating transmission line 1, etc., so as to transport items to the transmission section 21 in an orderly manner.

[0069] In some possible embodiments of this application, such as Figure 1 As shown, the transmission system also includes a marking device 6, which is correspondingly arranged with the cyclic transmission line 2 and located downstream of the portion of the cyclic transmission line 2 corresponding to the irradiation accelerator.

[0070] In some embodiments, a marking device 6 may be provided in the transmission system to identify irradiated objects. For example, the marking device 6 may be provided on the side of the circulating transmission line 1, or above the circulating transmission line 1, or on the portion of the circulating transmission line 1 downstream of the irradiation accelerator.

[0071] For example, the marking device 6 may include an inkjet printer, which can be positioned above the circulating transmission line 1, for example, upstream of the connection between the external section 12 and the shielding section 11. The marking device 6 may also be a laser marking machine, positioned upstream of the external section 12. Thus, after the irradiated object passes through the irradiation zone of the irradiation accelerator and reaches the location of the marking device 6 via the shielding section 11, the marking device 6 can be controlled to inkjet print or mark symbols on the irradiated object. Each time the irradiated object passes through the marking device 6, the marking device 6 can be controlled to inkjet print or mark symbols on the marked object once.

[0072] The transmission system for an irradiation accelerator provided in this application embodiment has a marking device 6 on the circulating transmission line 1. The marking device 6 can mark the irradiated object that has been irradiated once, which facilitates the identification of the irradiated object and makes it easy to determine the number of times the irradiated object has been irradiated based on the number of markings.

[0073] In addition, this application embodiment also provides an irradiation system, which includes: an irradiation accelerator and a transmission system for the irradiation accelerator provided in any of the above embodiments; wherein the irradiation accelerator is used to generate an electron beam or an X-ray beam; the irradiation accelerator is arranged adjacent to the circulating transmission line 2, and the irradiation area of ​​the irradiation accelerator covers a portion of the circulating transmission line 2.

[0074] In some embodiments, the core structure of an irradiation accelerator includes an electron gun, an accelerating tube, a focusing system, a beam transport system, a scanning magnet, and a scanning box. High-speed electrons can be generated by the electron gun, and then accelerated to the required energy by the accelerating tube.

[0075] For example, an X-ray conversion target can be set in an irradiation accelerator to convert the kinetic energy of an electron beam into X-ray radiation, thereby enabling the irradiation accelerator to generate an electron beam or an X-ray beam.

[0076] In another example, the irradiation accelerator can be placed next to the circulating transport line 1, with the scanning box of the irradiation accelerator facing the circulating transport line 1, such as placing the scanning box directly above the circulating transport line 1 in the vertical (gravity) direction, so that the irradiation area of ​​the irradiation accelerator covers a part of the circulating transport line 1, thereby irradiating the object to be irradiated that is transported through the circulating transport line 1.

[0077] The irradiation system provided in this application includes the transmission system for irradiation accelerators provided in any of the above embodiments. Therefore, it can quickly and efficiently transport the object to be irradiated to the irradiation area of ​​the irradiation accelerator and quickly and efficiently transport the irradiated object to the next station, thereby improving the efficiency of the irradiation accelerator in irradiating the object to be irradiated.

[0078] This application also provides a control method for a transmission system of an irradiation accelerator. This control method is used in the transmission system provided in any of the above embodiments. The transmission system includes a circulating transmission line, a conveying transmission line, and a transfer device. (Refer to...) Figure 2 , Figure 2 This is the flow chart of the control method for the transmission system of an irradiation accelerator provided in this application. Figure 1 This control method can be implemented through steps S101 to S104, as described below. Figure 2 This control method is described.

[0079] S101, Control the conveyor line to transport the object to be irradiated to the circulating conveyor line.

[0080] In some embodiments, the conveying line 2 can be controlled to start conveying the material to be irradiated to the circulating conveying line 1 based on different control signals. For example, the control signal may be that the irradiation accelerator has started, the control signal may be that the number of materials to be irradiated has reached a preset number, the control signal may be that the production line of the materials to be irradiated, which is electrically connected to the transmission system, has started production, etc. The embodiments of this application do not limit the way the control signal is generated.

[0081] For example, the controller of the transmission system can control each part of the transmission system to perform its respective actions according to a preset method to complete the irradiation of the object to be irradiated. The controller can be a host computer electrically connected to each lower-level machine in the transmission system. The host computer can include a computer host and interactive devices such as a monitor, keyboard, and mouse. The host computer can monitor, acquire data, and issue commands to the lower-level machines (such as PLCs, microcontrollers, etc.). For example, after receiving a control signal, the host computer can issue control commands to the lower-level machines of the transmission line 2. The lower-level machines of the transmission line 2 respond to the received control commands to control each part of the transmission line 2 to perform its respective actions. For example, the buffer section 24 can be controlled to transport the object to be irradiated to the transmission section 21. After the object to be irradiated arrives at the transmission section 21 corresponding to the transfer device 3, the transmission section 21 can be controlled to stop operating so that the object to be irradiated can be transported to the circulating transmission line 1 through the transmission line 2.

[0082] S102, The control transfer device transfers the object to be irradiated from the conveyor line to the circulating conveyor line.

[0083] In some embodiments, after the object to be irradiated reaches the pickup range of the transfer device 3 on the conveying line 2, a portion of the conveying segment 21 in the conveying line 2 can be controlled to stop moving, and a control command can be sent to the transfer device 3. The transfer device 3 responds to the control command and performs a transfer action. That is, the transfer device 3 first picks up the object to be irradiated on the conveying line 2, then transfers the object to be irradiated to the top of the circulating conveying line 1, and then releases the object to be irradiated to place on the circulating conveying line 1, thereby completing the transfer of the object to be irradiated from the conveying line 2 to the circulating conveying line 1.

[0084] S103. Control the circulating conveyor line to carry the object to be irradiated through the irradiation zone of the irradiation accelerator at a preset speed; the irradiation accelerator is set on the arrangement path of the circulating conveyor line.

[0085] In some embodiments, before or after the object to be irradiated is transferred to the circulating transport line 1 via the transfer device 3, the circulating transport line 1 can be controlled to move at a preset speed. For example, the preset speed of the circulating transport line 1 can be set according to the irradiation time required for the object to be irradiated. If the object requires a longer irradiation time, the preset speed of the circulating transport line 1 can be set slower; if the object requires a shorter irradiation time, the preset speed of the circulating transport line 1 can be set faster. In this way, the circulating transport line 1 can carry the object to be irradiated through the irradiation zone of the irradiation accelerator at a preset speed, thereby completing one irradiation of the object.

[0086] S104. The control transfer device transfers the irradiated material that has passed through the irradiation zone on the cyclic conveyor line to the conveyor line.

[0087] In some embodiments, after the irradiated material has passed through the irradiation zone of the irradiation accelerator, the irradiated material can be transferred from the circulating transport line 1 to the conveying transport line 2. For example, after the irradiated material reaches the outer section 12 along with the shielding section 11, the transfer device 3 can be controlled to pick up the irradiated material at the upstream end of the outer section 12, and then the transfer device 3 can be controlled to transfer the picked-up irradiated material to the downstream upper part of the conveying transport line 2. Then, the transfer device 3 can be controlled to release the irradiated material onto the conveying transport line 2 so that the irradiated material can be transported to the next station via the conveying transport line 2.

[0088] The control method for the transmission system of an irradiation accelerator provided in this application embodiment, by controlling the conveyor line 2 to transport the object to be irradiated to the circulating conveyor line 1 and controlling the transfer device 3 to transfer the object to be irradiated from the conveyor line 2 to the circulating conveyor line 1, can control the rhythm of the transfer device 3 transferring the object to be irradiated to the circulating conveyor line 1 according to the number of objects to be irradiated on the circulating conveyor line 1, thereby reducing problems such as congestion of the object to be irradiated on the circulating conveyor line 1. Furthermore, controlling the circulating conveyor line 1 to move the object to be irradiated through the irradiation zone at a preset speed allows for irradiation of the object to be irradiated for an appropriate duration, which is beneficial to improving the irradiation quality of the object. Simultaneously, controlling the transfer device 3 to transfer the irradiated object to the conveyor line 2 allows for the rapid transport of the irradiated object to the next station via the conveyor line 2. Therefore, the control method for the transmission system of an irradiation accelerator provided in this application embodiment can improve the efficiency of the irradiation accelerator in irradiating the object to be irradiated.

[0089] Reference Figure 3 , Figure 3 This is the flow chart of the control method for the transmission system of an irradiation accelerator provided in this application. Figure 2 The transmission system also includes a flipping device, which is disposed on the circulating transmission line, and the transfer device includes a first transfer component and a second transfer component. Based on Figure 2 Step S102 can be implemented through S201, and step S104 can be implemented through S203. This control method also includes step S202, which will be discussed below. Figure 3 This control method is described.

[0090] S201, Control the first transfer unit to transfer the object to be irradiated from the upstream end of the conveying line to the circulating conveying line.

[0091] In some embodiments, after numerous items on the conveyor line 2 reach the pickup range of the first transfer member 31, the movement of the transport segment 21 and the first transfer member 31 in the conveyor line 2 can be controlled according to whether each item requires irradiation. For example, if some of the items to be irradiated among the numerous items require irradiation, when the items to be irradiated reach the transport segment 21 adjacent to the first transfer member 31, the transport segment 21 can be controlled to stop moving, so that the items to be irradiated are stationary. Then, a control command is issued to the first transfer member 31, which, in response to the control command, first picks up the items to be irradiated on the transport segment 21, then transfers the items to be irradiated to the tray 7 on the upstream end of the circulating conveyor line 1, and finally releases the items to be irradiated, thereby causing the items to be irradiated to move with the circulating conveyor line 1 towards the irradiation area of ​​the irradiation accelerator.

[0092] S202, control the flipping device to flip the irradiated material that has passed through the irradiation zone for the first time on the cyclic conveyor line, and control the cyclic conveyor line to drive the irradiated material that has passed through the irradiation zone for the first time to pass through the irradiation zone again.

[0093] In some embodiments, some objects to be irradiated may not have fully achieved the desired irradiation effect after one irradiation, so the irradiated objects that have already been irradiated once can be irradiated again.

[0094] For example, when the irradiated object, after its first irradiation, reaches the pickup range of the second transfer member 32 along the circulating transport line 1, the second transfer member 32 is not controlled to pick up the irradiated object. Instead, the irradiated object continues to move downstream of the outer section 12 of the circulating transport line 1 on the tray 7. When the irradiated object reaches the position of the flipping device 4 located on the outer section 12, the flipping device 4 can be controlled to pick up the irradiated object first, and then the flipping device 4 can be controlled to rotate the irradiated object by 90°, 180°, etc., and then the irradiated object is released onto the tray 7. This allows the irradiated object to move again along the circulating transport line 1 towards the irradiation area of ​​the irradiation accelerator. At this time, the other unirradiated surface of the irradiated object faces the irradiation accelerator until the irradiated object passes through the irradiation area of ​​the irradiation accelerator again along the circulating transport line 1, thus completing the re-irradiation of the irradiated object.

[0095] S203, Control the second transfer unit to transfer the irradiated material that has passed through the irradiation zone for the second time from the circulating conveyor line to the downstream of the conveyor line.

[0096] In some embodiments, after the irradiated object, having undergone a second irradiation, moves along the circulating conveyor line 1 to the pickup range of the second transfer member 32, a stop device can be controlled to perform a stop action, causing the tray 7 supporting the irradiated object to stop moving relative to the second transfer member 32. The second transfer member 32 is then controlled to pick up the irradiated object and transfer it downstream of the conveyor line 2, that is, to the portion of the conveyor section 21 near the output section 23. In this way, the same object can be irradiated twice. If it is necessary to irradiate the same object three or more times, the object can be flipped multiple times by the flipping device 4 so that different surfaces of the object face the irradiation accelerator.

[0097] For example, if the items on the conveyor line 2 do not require irradiation, the first transfer member 31 can be controlled not to perform a transfer action, thereby allowing the items that do not require irradiation to move to the next station on the conveyor line 2.

[0098] The control method for the transport system of an irradiation accelerator provided in this application embodiment can complete the first irradiation of the object to be irradiated by controlling the first transfer member 31 to transfer the object to be irradiated onto the circulating transport line 1. Furthermore, the flipping device 4 flips the irradiated object to facilitate secondary irradiation. Thus, by controlling different parts of the transport system for an irradiation accelerator provided in this application embodiment, it is possible to achieve primary irradiation, secondary irradiation, and non-irradiated transport of items, thereby meeting the needs of different irradiation processes for various items and improving the process flexibility of the transport system for an irradiation accelerator provided in this application embodiment.

[0099] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
