Fig. 4 is a flowchart of a method for controlling sterilization of the system 10 according to another embodiment of the present invention. Referring to fig. 4, the method is applied to an irradiation system, and comprises the following steps:
s4001: the irradiation object 20 is placed on the loading section 210. The feeding section 210 may further be provided with a pretreatment device 800 for pretreating the irradiation object 20.
S4002: the controller 300 controls the feeding section 210 to transport the irradiation object 20 to the pre-beam transport section.

S4005: the controller 300 controls the first accelerator 110 and the second accelerator 120 to emit electron beams to perform radiation sterilization on a portion of the surface of the irradiated object 20 on the under-beam transport section at the irradiation zone.

s4008: the controller 300 controls the under-beam transport section to transport the irradiation object 20 to the irradiation object again, and then transports the irradiation object 20 to the post-beam transport section.
S4009: the controller 300 controls the post-beam transportation section to transport the irradiation object 20 to the discharging section 220.
S4010: the controller 300 controls the discharging section 220 to output the irradiation object 20.
In some embodiments, when the number of times the irradiation object 20 passes through the irradiation zone is less than or equal to 1, the irradiation object 20 is transported again to the irradiation zone via the under-beam transport section to perform the irradiation treatment on the remaining surface of the irradiation object 20.
That is, when the irradiation object 20 is transported to the irradiation region, it is necessary to judge the number of times it passes through the irradiation region. When the number of times that the object 20 passes through the irradiation region is less than or equal to 1, the object 20 passes through the irradiation region only once, so that three sides of the object 20 are sterilized by irradiation, and the other three sides are irradiated surfaces and need to be processed again. Since the first accelerator 110 and the second accelerator 120 of the irradiation device 100 can simultaneously perform irradiation processing on three surfaces of the irradiation object 20, if it is determined that the number of times that the irradiation object 20 passes through the irradiation region is less than or equal to 1, the irradiation object 20 may have only three surfaces irradiated through the irradiation region or each surface is not irradiated.
In some embodiments, when the number of times of passing the irradiation region by the irradiation object 20 is less than or equal to 1, the irradiation object 20 is first transported to the turnover device 900 via the under-beam transport section, and after the turnover device 900 turns the irradiation object by 180 °, the irradiation object 20 is transported to the irradiation region again via the under-beam transport section.
When the irradiation object 20 is turned over by the device 900, the non-irradiation surface of the irradiation object 20 is parallel to the running direction of the irradiation object 20.
In some embodiments, a coding device may also be provided. The code attaching device is provided on one side of the under-beam transport section and downstream of the irradiation device 100 to mark the number of times the irradiation object 20 passes through the irradiation zone.
In some embodiments, an identification device may also be provided. The identification device is arranged on one side of the under-beam transport section and is positioned downstream of the code sticking device to identify the number of times the irradiation object 20 passes through the accelerator.
In some implementations, the first accelerator 110 includes a scanning box and a scanning magnet and a deflecting magnet installed outside the scanning box to implement deflection of the electron beam toward the scanning magnet and the deflection, thereby implementing three-sided irradiation of the irradiation object 20 by the first accelerator 110 and the second accelerator 120.
In some embodiments, the packaging box is pre-treated and then transported through the feeding section 210, the packaging box is transported through the pre-bundle transport section to the under-bundle transport section, the under-bundle transport section transports the packaging box to the irradiation zone, and the irradiation zone performs irradiation sterilization on three surfaces of the packaging box. The irradiated package is then palletized to indicate that the package has undergone one irradiation. The irradiated packing box reaches the judgment area through the transportation of the under-beam transportation section, and the code attached to the packing box is identified through the identification device arranged in the judgment area so as to judge whether the times of the irradiated object 20 passing through the irradiation area is less than or equal to 1. When the times that the irradiated objects 20 pass through the irradiation area are less than or equal to 1, and in order to ensure the completeness of sterilization of the packaging box, the packaging box needs to be irradiated again; when the number of times that the irradiation thing 20 passes through irradiation zone 0 is greater than 1, it indicates that the number of times that the irradiation thing 20 passes through the irradiation zone is greater than 1, because the packing box is the hexahedron, six surfaces of the packing box of this moment all have been irradiated and sterilized, in order to avoid the waste, can transport section and ejection of compact section 220 output after the packing box passes through successively, indicate that six face of this packing box have been disinfected.
In another embodiment, the packaging boxes are stacked before entering the under-bundle transportation system 200, then are pre-processed and then are transported through the feeding section 210, the packaging boxes are transported to the under-bundle transportation section through the pre-bundle transportation section, a first bar code detection device is arranged before the under-bundle transportation section transports the packaging boxes to the irradiation area, the numerical values of the bar codes on the packaging boxes are read through the first bar code detection device, and each different packaging box has a corresponding bar code because the numerical values on each bar code are different. The packaging box passes through the first bar code detection device and then is transported to an irradiation area, and the irradiation area performs irradiation sterilization on three surfaces of the packaging box. The irradiated packing box reaches the judgment area through the transportation of the under-beam transportation section, the bar codes on the packing box are identified and one side is counted through a second bar code detection device arranged in the judgment area, and whether the times of the irradiated object 20 passing through the irradiation area is less than or equal to 1 or not is judged. When the times that the irradiated objects 20 pass through the irradiation area are less than or equal to 1, and in order to ensure the completeness of sterilization of the packaging box, the packaging box needs to be irradiated again; when the number of times that the irradiation object 20 passes through the irradiation zone is greater than 1, and the packing box is hexahedron, so six outer surfaces of the packing box at this moment all have been subjected to irradiation sterilization, and in order to avoid waste, the packing box can be output through the rear transport section and the discharge section 220 in sequence, and the packing box is shown to have finished six-surface sterilization.
